VERTEX, INC.
Class A Common Stock



         This is Vertex, Inc.'s initial public offering. We are selling 21,150,000 shares of our Class A common stock. The public offering price is $19.00 per share. Currently, no public market exists for our Class A common stock. The shares of our Class A common stock will trade on the Nasdaq Global Market under the symbol "VERX."



         Following this offering, we will have two classes of authorized common stock, Class A common stock and Class B common stock. The rights of the holders of Class A common stock and Class B common stock will be identical, except with respect to voting, conversion and transfer rights. Each share of Class A common stock will be entitled to one vote per share. Each share of Class B common stock will be entitled to ten votes per share and will be convertible into one share of Class A common stock. Outstanding shares of Class B common stock will represent approximately 98% of the voting power of our outstanding capital stock immediately following the completion of this offering, with members of our founder's family, and their respective affiliates, holding approximately 98% of the voting power of our capital stock following this offering. As a result, we will be a "controlled company" within the meaning of the corporate governance standards of the Nasdaq Global Market.

PROSPECTUS SUMMARY

Overview

        Our vision is to accelerate global commerce, one transaction at a time.

        Vertex delivers comprehensive tax solutions that enable global businesses to transact, comply and grow with confidence. Companies with complex tax operations rely on Vertex to automate their end-to-end indirect tax processes. Indirect tax is the largest corporate tax category, encompassing sales tax, seller's use tax, consumer use tax and value-added tax ("VAT"), among others. Indirect tax accounts for more than $3.5 trillion of annual tax revenue, which is 2.5 times the amount of corporate income taxes, according to the 2019 OECD Tax Database. Our software, content and services address the increasing complexities of global commerce and compliance by reducing friction, enhancing transparency and enabling greater confidence in meeting indirect tax obligations. As a result, our software is ubiquitous within our customers' business systems, touching nearly every line item of every transaction that an enterprise can conduct. Today, we have more than 4,000 customers, including over half of the Fortune 500, and provide our customers with tax support in over 130 countries.

        Tax complexity is driven by the number of jurisdictions, products, distribution channels and systems of record within an organization. Each transaction must be tax-assessed for compliance purposes in real time and indirect taxes generally require filing each month, in every jurisdiction in which a company does business. Despite these complexities, there are still businesses that attempt to manage the tax lifecycle through a patchwork of static tax rate tables in spreadsheets, home-built systems or business applications, such as enterprise resources planning ("ERP") software, that were not designed for complex tax management. Each of these approaches relies heavily on finance personnel or outside professional services.

        The rapid changes taking place in today's global business, technology and regulatory environments are having a compounding effect on the complexity of indirect tax management. As companies expand their business models, enter new geographies and extend their distribution channels, they widen the aperture of their indirect tax obligations. Additionally, as they expand their core offerings to incorporate new digital products and services, they are increasingly impacted by new tax regulations being pursued by jurisdictions. For example, in the United States, nearly 40 states have now enacted marketplace facilitator regulations, requiring online marketplaces to collect and remit taxes for first- and third-party sales on their websites. This complexity demands intelligent solutions that enable businesses to satisfy tax obligations and support growth opportunities.

        We have pioneered tax technology for over 40 years. We first began electronic delivery of tax rules in the early 1980s and we first sold transaction tax processing software in 1982. Today, our software enables tax determination, compliance and reporting, tax data management and document management with powerful pre-built integrations to core business applications used by most companies, particularly those applications that have a significant impact on global commerce. Our software is fueled by over 300 million data-driven effective tax rules and supports indirect tax compliance in more than 19,000 jurisdictions worldwide. In order to maintain the quality of our content, our team includes many global tax and regulatory experts from industry and the public sector, who deliver monthly updates to our tax content, which are then incorporated directly into our software. Our solutions can be deployed on-premise, in the cloud, or both, with implementation services available to enable optimal customer outcomes and satisfy unique business requirements.

        Our customers include the majority of the Fortune 500, as well as a majority of the top 10 companies by revenue in multiple industries such as retail, technology and manufacturing, in addition to leading marketplaces. As these companies expand geographically and pursue omnichannel business models, their tax determination and compliance requirements increase and become more complex. Our

trusted brand and strong relationships with our customers enable us to capitalize on these sustainable organic growth opportunities.

        Our partner ecosystem is a differentiating, competitive strength in both our software development and our sales and marketing activities. We integrate with key technology partners that span ERP, customer relationship management ("CRM"), procurement, billing, point of sale ("POS") and eCommerce. These partners include Adobe/Magento, Coupa, Microsoft Dynamics, NetSuite, Oracle, Salesforce, SAP, SAP Ariba, Workday and Zuora. We also collaborate with numerous accounting firms who have built implementation practices around our software to serve their customer base.

        We believe that global commerce and compliance environment provides durable and accelerating growth opportunities for our business. We generated revenue of $272.4 million and $321.5 million in 2018 and 2019, respectively, and $74.6 million and $89.2 million for the three months ended March 31, 2019 and 2020, respectively. We had a net loss of $6.1 million and net income of $31.1 million in 2018 and 2019, respectively, and net income of $7.3 million and a net loss of $29.1 million for the three months ended March 31, 2019 and 2020, respectively. Adjusted EBITDA was $61.5 million and $67.9 million in 2018 and 2019, respectively, and $15.6 million and $15.3 million for the three months ended March 31, 2019 and 2020, respectively. Additionally, we generated net cash provided by operating activities of $80.4 million and $92.5 million in 2018 and 2019, respectively, and $9.9 million and $(6.4) million in the three months ended March 31, 2019 and 2020, respectively. Our free cash flow was $47.1 million and $54.9 million in 2018 and 2019, respectively, and $1.8 million and $(15.8) million in the three months ended March 31, 2019 and 2020, respectively. Adjusted EBITDA and free cash flow are non-GAAP financial measures. For more information about how we use these non-GAAP financial measures in our business, the limitations of these measures and reconciliations to the most directly comparable GAAP measures, see "Prospectus Summary—Summary Consolidated Financial and Operating Information." In connection with the offering, we will convert from an S Corporation to a C Corporation ("C Corporation"), which will result in net income of the Company being taxed at the corporate level. For additional information on the effect of such conversion, see "Prospectus Summary—Summary Consolidated Financial and Operating Information."


Industry Background

Indirect taxes are significant and growing revenue streams for governments around the world

        Indirect taxes are part of everyday commerce in many countries—they are levied on items such as food, clothing, business supplies and even data transmissions from mobile phones. According to the 2019 OECD Tax Database, more than $3.5 trillion of indirect taxes were collected by national, state and local governments around the world in 2018, which is 2.5 times the amount of corporate income taxes collected. Indirect taxes on goods and services represented more than 10% of GDP for OECD countries in 2018 and governments continuously seek new ways to increase this revenue stream. In the United States, sales and use taxes are the largest component of indirect taxes. According to OECD Revenue Statistics, the United States collected more than $800.0 billion in tax revenue from goods and services taxes in 2018.

Tax reporting and compliance pose tenacious challenges for all businesses

        In today's global economy, indirect taxation is highly nuanced and growing in its complexity for most businesses. In order to calculate taxes accurately, enterprises must identify every jurisdiction in which they operate, determine and maintain the applicable rates for each of those jurisdictions and map the applicable taxability to the products and services they deliver. Cross-border transactions increase the complexity of taxes. Understanding the variables surrounding transactions and how they change applicable taxes becomes difficult for tax departments to manage given the volume of purchasing, sourcing and sales activities conducted by large enterprises.

Table of Contents

        Indirect tax returns generally need to be filed on a monthly basis and noncompliance exposes companies to significant monetary liability, poor customer experiences and reputational risk. Tax audits can look back many years, creating a greater level of accountability for managing tax data than for typical business data. Additionally, it is not unusual for a large enterprise to have a substantial number of tax audits across numerous jurisdictions ongoing at any point in time. Each audit may require detailed traceability to individual transactions to defend historical tax positions taken.

Dynamic business, regulatory and technology drivers have a compounding effect on tax compliance

        We believe that trends in the digital economy are accelerating the need for adoption of sophisticated tax solutions among a broader and growing number of enterprises and global commerce platforms.

    Governments are increasingly adopting new and expanded indirect tax measures.

    Governments are mandating more frequent and more detailed tax reporting, using advanced technologies to scrutinize business tax filings.

    Businesses' geographic and channel expansion are creating new tax exposures.

    Governments are enacting new taxation on digital goods and services.

    Business-to-consumer ("B2C") and business-to-business ("B2B") marketplaces are increasingly responsible for collecting and remitting taxes for their third-party sellers.

    The expanded number of business applications being used by enterprises has increased the number of data sources necessary for indirect tax compliance.

Legacy approaches are insufficient

        Over the past several decades, many tax departments have addressed their indirect tax needs by relying on a patchwork of static tax rate tables in spreadsheets, home-built systems or business applications not designed for tax compliance. Each requires heavy reliance on finance personnel or outside professional services. As taxation becomes more complicated, we believe these approaches will begin to fracture as they are error-prone, inefficient and cannot scale, thus increasing exposure to fines, raising reserves and heightening the risk of tax audits across multiple jurisdictions.


Our Opportunity

        We believe the total addressable market for solutions that enable global commerce and compliance is robust, global and growing. We estimate our addressable market among global enterprises and other businesses with greater than $1.0 million in annual sales to be over $7.0 billion in the United States. We believe this potentially understates our total addressable market because it does not include businesses domiciled outside of the United States.


Key Benefits of Our Solutions

        We deliver comprehensive tax solutions that automate end-to-end indirect tax processes for enterprises and mid-market companies with complex tax operations. Our software includes tax determination, compliance and reporting, tax data management and document management fueled by our powerful and proprietary content database, which includes over 300 million data-driven effective tax rules supporting indirect tax compliance in more than 19,000 jurisdictions worldwide. Our solutions also include powerful pre-built integrations to core business applications, such as SAP and Oracle.

Table of Contents

        Our solutions deliver the following key benefits to our customers:

        Comprehensive, efficient and accurate indirect tax management.    Our solutions provide our customers with powerful tools to manage their end-to-end indirect tax processes and manage their indirect tax obligations accurately and efficiently, while reducing risk.

        Reduction in tax audit risk and tax audit-induced costs.    We believe that customers implement our solutions to increase accuracy and transparency in supporting the tax audit process, and to lower their overall costs of tax audit defense. This is driven by rich documentation and data support during tax audit discovery, which can mitigate tax audit-related adjustments and fines.

        Wide jurisdiction coverage to support geographic expansion.    Economic nexus for indirect taxes is often based on the geographic location of either operations or sales. We maintain expansive coverage of jurisdictions and continually update our global content database, allowing our customers to expand their operations around the world while maintaining compliance with the relevant indirect tax laws of each jurisdiction.

        Support of new business models.    As digital transformation continues to change our economy, many enterprises are adopting new business models and incorporating new technology in their products and operations to fuel growth, including diversified supply chains and omnichannel retail strategies. Many of these digital transformations result in new, complex indirect tax challenges. For example, data transmissions from internet-connected devices are subject to telecom taxes, which are often new and unfamiliar obligations to traditional manufacturers and retailers.


Our Competitive Strengths

        We have pioneered tax technology for over 40 years. We deliver comprehensive tax solutions that enable global businesses to transact, comply and grow with confidence. Companies with complex tax operations rely on us to automate their end-to-end indirect tax processes. Our key competitive strengths include:

        We provide a differentiated portfolio of end-to-end solutions for indirect tax globally.    Our solutions automate the end-to-end indirect tax processes for enterprises with complex tax operations and audit risk.

Customers can purchase these solutions individually or as part of a broader suite and can choose the delivery model that best aligns to their enterprise technology environments.

        Our software is underpinned by a comprehensive proprietary tax content database.    Our proprietary tax content database is significant and includes educational content, best practices guidance and over 300 million data-driven effective tax rules supporting indirect tax compliance in more than 19,000 jurisdictions worldwide, which are then embedded into our software. Our tax content provides meaningful insights and guidance to enterprises looking to address their tax exposure and we provide solutions by embedding these tax rules into our software.

recognition of our customer base and the mission-critical nature of our software for tax departments, provide leverage to our sales and marketing teams and enable us to successfully attract new customers.

        Powerful, robust technology with enterprise-grade scale and speed.    Our solutions are built upon a technology foundation purpose-built to meet the needs of highly discerning enterprises with complex indirect tax obligations. For example, our software is used by some of the largest companies in the world to automate indirect tax calculation in hundreds of locations, among thousands of suppliers and millions of customers, across tens of thousands of jurisdictions, and through multiple systems of record.

Our configurability allows users to create their own taxability rules that can act as an override providing more flexibility and ensuring that all individual, company-specific tax scenarios can be met. We also offer a flexible delivery model that includes on-premise, cloud or a hybrid of both delivery models, giving our customers the ability to choose how to manage their tax determination and system deployments.

        Deep and high-quality partnerships and integrations.    Our partner ecosystem is a distinct strength to support both software development and our sales and marketing activities. We integrate with key technology partners that span ERP, CRM, procurement, billing, POS and eCommerce platforms. Our teams are embedded at a deep technical level and we conduct joint roadmap development with our partners. In addition, we collaborate with over 50 tax, accounting and consulting firms, which not only complement our global tax and technology expertise, but also help us identify new growth opportunities.


Our Growth Strategies

        We believe today's global commerce environment provides durable growth opportunities for our business. Our growth strategies include:

    Expand existing customer revenues.  The breadth of our solutions allows us to continually meet our customer needs, even as their needs expand in scope. As businesses continue to evolve through acquisitions and expand products and services, enter new geographies or expand their distribution channels, we believe they will need our software, services and content. We plan to continue to invest in new offerings and enhance our solutions to support the ongoing retention and expansion of revenue from our existing customers.

    Acquire new customers.  As enterprise and mid-market companies continue to expand and their tax complexity grows, we expect demand for our solutions to increase among new customers and partners. We also expect these companies to adopt our solutions much earlier in their corporate lifecycle. This adoption is driven by advances in cloud computing and digital commerce, which enable more companies to accelerate new product delivery and scale their business through online marketplaces and emerging commerce platforms.

    Broaden and deepen our partner ecosystem.  Our partners enhance our go-to-market capacity and extend our brand leadership and reach. We leverage our partnerships to maximize the benefits of our solutions for our customers and to identify new growth opportunities. We believe expanding our strategic alliances with emerging participants who are fueling global commerce, such as payment and digital commerce platforms, will create new value for our customers and new sources of revenue.

    Extend global footprint.  We have a significant opportunity to further expand internationally, in terms of our regional operations, content depth and go-to-market coverage. By extending our global footprint, we believe we will also expand account penetration of existing customers with operations around the globe.

    Sustained investment in new product innovation.  Our approach to innovation is driven by our relationships with our customers and partners, with whom we create new solutions, align product roadmaps and embed our software within their platforms. We have also established an innovation lab where we design, test and incubate next-generation tax solutions and adjacent market opportunities like blockchain, payment platforms and machine learning technologies. Over time, we expect this will bring additional value to existing customers and help us acquire new customers.


Recent Developments

        Set forth below are certain estimated preliminary financial results and other key operating metrics for the three months ended June 30, 2020. These estimates represent the most current information available and are subject to change. We have provided ranges, rather than specific amounts, for the preliminary results described below because our financial closing procedures for the quarter ended June 30, 2020 are not yet complete. Our actual results may differ materially from these estimates due to the completion of our financial closing procedures, final adjustments and other developments that may arise between now and the time the financial results for our three months ended June 30, 2020 are finalized.

        These estimates should not be viewed as a substitute for our full interim or annual financial statements prepared in accordance with GAAP. Accordingly, you should not place undue reliance on this preliminary data. These estimated preliminary results should be read in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations" and the consolidated financial statements and related notes thereto included elsewhere in this prospectus. For additional information, please also refer to the section titled "Risk Factors."

        This data has been prepared by, and is the responsibility of, management. Our independent registered public accounting firm, Crowe LLP, has not audited, reviewed, compiled or performed any procedures with respect to the preliminary financial results. Accordingly, Crowe LLP does not express an opinion or any other form of assurance with respect thereto.

        The following are preliminary estimates for the quarter ended June 30, 2020:

        For the three months ended June 30, 2020, estimated total revenue was between $88.0 million and $91.0 million, compared to $78.4 million for the same period in 2019. This represents an increase of $11.1 million, or 14.2% year-over-year at the midpoint, compared to the same period in 2019. Annual Recurring Revenue ("ARR") was between $292.0 million and $295.0 million for the three months ended June 30, 2020, representing an increase of $40.5 million, or 16.0% year-over-year at the midpoint, compared to the same period in 2019. The growth of our revenue and ARR reflects the increase in revenue from existing customers through their expanded use of our solutions, new software subscriptions and price increases and as well as sales of our tax solutions to new customers.

        We have an expected loss from operations for the three months ended June 30, 2020, which is between $28.0 million and $32.0 million, compared to operating income of $7.7 million in the same period in 2019. The operating loss was primarily a result of higher stock-based compensation expense associated with this offering. Stock-based compensation expense was between $41.0 million and $42.0 million.

        Adjusted EBITDA for the three months ended June 30, 2020, was between $18.0 million and $21.0 million, representing a year-over-year increase of $4.0 million at the midpoint, as compared to

Table of Contents

the same period in 2019. This was primarily driven by an increase in total revenues and gross profit offset by increased operating expenses, including additional research and development and general and administrative expenses. Adjusted EBITDA margin increased for the three months ended June 30, 2020 by between approximately 200 basis points at the midpoint as compared to the same period in 2019. This is primarily due to revenue and gross margin increasing at a higher rate than our growth in operating expenses which were impacted by delays in hiring and launch of projects and decreases in travel and other operating activities due to the COVID-19 pandemic limiting such activities.

        Set forth below is a reconciliation of Adjusted EBITDA to the most directly comparable measure calculated in accordance with GAAP, net loss.

Summary Risk Factors

        Investing in our Class A common stock involves substantial risk. Our ability to execute our strategy is also subject to certain risks. The risks described under the heading "Risk Factors" in this prospectus may cause us not to realize the full benefits of our strengths or may cause us to be unable to successfully execute all or part of our strategy. Some of the most significant challenges and risks we face include the following:

    A large portion of our revenue depends on maintaining and growing our revenue from existing customers, and if we fail to retain our customers or expand their usage of our solutions, our business, results of operations, financial condition and cash flows would be harmed.

    Our business and success depend in part on our strategic relationships with third parties, including our partner ecosystem, and our business would be harmed if we fail to maintain or expand these relationships.

    If we are unable to adapt to technological change by successfully introducing new and enhanced solutions and services, our business, results of operations, financial condition and cash flows would be adversely affected.

Table of Contents

    Any failures in information technology or infrastructure could lead to disruptions of our software, loss of customer data or untimely remittance of taxes, any of which could adversely affect our reputation and financial condition.

    Incorrect or improper implementation, integration or use of our solutions could result in customer dissatisfaction and negatively affect our business, results of operations, financial condition and cash flows.

    If we fail to attract and retain qualified technical and tax-content personnel, our business could be harmed.

The Offering

Class A common stock offered by us

  21,150,000 shares (or 23,812,216 shares if the underwriters exercise in full their option to purchase additional shares).

Class A common stock to be outstanding after this offering

 

22,576,819 shares (or 25,749,319 shares if the underwriters exercise in full their option to purchase additional shares).

Class B common stock to be outstanding after this offering

 

120,417,000 shares.

Option to purchase additional shares of Class A common stock

 

The underwriters have an option to purchase up to an aggregate of 3,172,500 additional shares of Class A common stock from us and the selling stockholders at the initial public offering price, less underwriting discounts and commissions. Of these shares, 510,284 will be offered and sold by the selling stockholders upon exercise of stock options held by such selling stockholders. The underwriters can exercise this option at any time within 30 days from the date of this prospectus. We will not receive any proceeds from any sale of our shares of Class A common stock in this offering by the selling stockholders. The selling stockholders will only sell shares of Class A common stock in this offering if the underwriters exercise their option to purchase additional shares. In the event the underwriters do not exercise their option to purchase additional shares in full, the underwriters will first purchase shares from the selling stockholders, with any remaining shares being sold by us.

Use of proceeds

 

We estimate that the net proceeds to us from the sale of the shares of our Class A common stock in this offering will be approximately $369.4 million after deducting underwriting discounts and commissions and estimated offering expenses payable by us. If the underwriters exercise their option to purchase additional shares in this offering in full, we estimate that our net proceeds will be approximately $416.7 million, after deducting underwriting discounts and commissions and estimated offering expenses payable by us. We will not receive any of the proceeds from any sale of shares in this offering by the selling stockholders.

Table of Contents

 

We intend to use a portion of the net proceeds to repay all outstanding indebtedness under our existing credit agreement (the "New Credit Agreement") and to pay related fees and expenses. Prior to this offering, proceeds from the term loan entered into under the New Credit Agreement were used to repay amounts outstanding under the Company's previous credit agreement of $61.7 million, with the balance being used to fund a portion of a $123.0 million dividend to our stockholders on May 29, 2020 $122.8 million of which was paid to our directors Amanda Westphal Radcliffe, Stefanie Westphal Thompson and Jeffrey Westphal or trusts for their respective benefit or the benefit of their immediate family. In addition, we intend to use approximately $22.9 million of the proceeds from this offering to pay for costs we expect to incur in connection with the amendment of outstanding SARs as part of this offering. See "Executive Compensation." The remainder of the net proceeds will be used for working capital and other general corporate purposes, including investments in our solutions, technology and sales force. See "Use of Proceeds."

Dividend policy

 

Historically, we have been an S Corporation, and, as such, we have paid distributions to our existing stockholders, which have assisted them in paying the U.S. federal and state income taxes on our taxable income that is "passed through" to them, and we have historically made additional distributions to them for returns on capital. After this offering, our dividend policy and practice will change because we will no longer be taxed as an S Corporation. We do not currently anticipate paying dividends on our Class A or Class B common stock. Any declaration and payment of future dividends to holders of our Class A or Class B common stock may be limited by restrictive covenants in the agreements governing our indebtedness, will be at the sole discretion of our board of directors and will depend on many factors, including our financial condition, earnings, capital requirements, level of indebtedness, statutory and contractual restrictions applying to the payment of dividends and other considerations that our board of directors deems relevant. See "Dividend Policy."

Directed share program

 

At our request, the underwriters have reserved for sale, at the initial public offering price, up to 5% of the Class A common stock offered by this prospectus for sale to some of our directors, officers, employees, business associates and related persons. If these persons purchase reserved shares, it will reduce the number of shares available for sale to the general public. Any reserved shares that are not so purchased will be offered by the underwriters to the general public on the same terms as the other shares offered by this prospectus. See "Underwriting."

      stockholders of options to purchase a net amount of 510,284 shares of our Class A common stock, which such net exercise would result in 13,033,107 remaining shares of our Class A common stock, issuable upon the exercise of options to purchase shares of our Class A common stock with a weighted-average exercise price of $2.39);

    9,887 shares of Class A common stock that will be issuable upon the vesting of RSUs to be awarded under the 2020 Plan to certain non-U.S. employees in connection this offering;

    the termination of our status as an S Corporation, which occurred on July 27, 2020;

Summary Consolidated Financial and Operating Information

        The following table sets forth our summary historical consolidated financial information for the periods and dates indicated. The consolidated balance sheet data as of December 31, 2019 and 2018 and the consolidated statements of comprehensive income (loss) for the years ended December 31, 2019 and 2018 have been derived from our audited consolidated financial statements included elsewhere in this prospectus. The consolidated balance sheet data as of March 31, 2020 and the consolidated statements of comprehensive income (loss) for the three months ended March 31, 2020 and 2019 have been derived from our unaudited consolidated financial statements appearing elsewhere in this prospectus. The unaudited interim consolidated financial statements have been prepared on the same basis as the audited annual consolidated financial statements and reflect, in the opinion of management, all adjustments of a normal, recurring nature that are necessary for a fair statement of the unaudited interim consolidated financial statements.

        The financial information set forth below is not necessarily indicative of future results of operations. In particular, we have historically been taxed as an S Corporation for U.S. federal income tax purposes and for income tax purposes in most states. As a result, net income or loss has been allocated to our stockholders and included on their individual income tax returns. Effective July 27, 2020, we converted to a C Corporation, which will result in net income of the Company being taxed at the corporate level after this date. As such, our provision for taxes will change. Upon the conversion to a C Corporation, we estimate that the Company's effective tax rate will be approximately 25%, inclusive of all applicable U.S. federal, state, local and foreign income taxes. In addition, based on the deferred tax asset balances at March 31, 2020, we would anticipate recording a tax benefit of approximately $8.5 million as if such conversion occurred on such date.

        Share amounts for all periods presented, including the number of shares that common stock equivalents are convertible into, were retrospectively restated to reflect the three-for-one forward stock split, which was effective on July 28, 2020.

        This data should be read in conjunction with, and is qualified in its entirety by reference to, the "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Capitalization" sections of this prospectus and our audited consolidated financial statements and notes thereto for the periods and dates indicated included elsewhere in this prospectus. Revenue is reflected in accordance with Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers, ("ASC 606"), which we adopted on January 1, 2018.

Adjusted EBITDA and Adjusted EBITDA margin are a non-GAAP financial measure used by our management and board of directors in measuring trends and our financial performance. In addition, we believe that Adjusted EBITDA and Adjusted EBITDA margin are measures widely used by securities analysts and investors to evaluate the financial performance of our company and other companies. We consider Adjusted EBITDA and Adjusted EBITDA margin to be important measures because we believe that they provide useful information in understanding and evaluating our operating results on a period over period basis without the impact of certain expenses that do not directly correlate to our operating performance and that can vary significantly from period to period. In addition, we base certain of our forward-looking estimates and budgets on Adjusted EBITDA and Adjusted EBITDA margin. We define Adjusted EBITDA as net income or loss before interest, taxes, depreciation and amortization, asset impairments, share-based compensation expense and severance charges. We define Adjusted EBITDA margin as Adjusted EBITDA divided by total revenues for the same period.


Our definitions of Adjusted EBITDA and Adjusted EBITDA margin may differ from the definitions used by other companies and therefore comparability may be limited. In addition, other companies may not publish these or similar metrics. Thus, our Adjusted EBITDA and Adjusted EBITDA margin should be considered in addition to, not as a substitute for, or in isolation from, measures prepared in accordance with GAAP. The following table reconciles Adjusted EBITDA to the most directly comparable GAAP financial performance measure, which is net income (loss):

Our management uses free cash flow as a critical measure in the evaluation of liquidity in conjunction with related GAAP amounts. It also uses the measure when considering available cash, including for decision making purposes related to dividends and discretionary investments. We consider free cash flow to be an important measure for investors because it measures the amount of cash we generate from operating activities after our capital expenditures and capitalization of

    software development costs. In addition, we base certain of our forward-looking estimates and budgets on free cash flow and free cash flow margin. We define free cash flow as the total of net cash provided by operating activities less purchases of property and equipment and capitalized software. We define free cash flow margin as free cash flow divided by total revenues for the same period.


Our definitions of free cash flow and free cash flow margin may differ from the definitions used by other companies and therefore comparability may be limited. In addition, other companies may not publish these or similar metrics. Thus, our free cash flow and free cash flow margin should be considered in addition to, not as a substitute for, or in isolation from, measures prepared in accordance with GAAP. The following table reconciles free cash flow to the most directly comparable GAAP financial performance measure, which is net cash provided by operating activities:

RISK FACTORS

        An investment in our Class A common stock involves a high degree of risk. You should consider carefully the following risks, together with the information under the caption "Business—Competition," our financial statements and the related notes and the other information contained in this prospectus before you decide whether to buy our Class A common stock. If any of the events contemplated by the following discussion of risks should occur, our business, results of operations, financial condition and cash flows could suffer significantly. As a result, the market price of our Class A common stock could decline, and you may lose all or part of the money you paid to buy our Class A common stock. The risks described below are those that we believe are the material risks that we face but other risks may arise from time to time. See "Cautionary Note Regarding Forward-Looking Statements" elsewhere in this prospectus.

Risks Relating to Our Business and Industry

A large portion of our revenue depends on maintaining and growing our revenue from existing customers, and if we fail to retain our customers or expand their usage of our solutions, our business, results of operations, financial condition and cash flows would be harmed.

        We cannot accurately predict customer behavior. Our customers have no obligation to renew their subscriptions for our solutions after the expiration of their subscription periods and our customers may not renew subscriptions for a similar mix of solutions. Our retention rates would decline as a result of a number of factors, including customer dissatisfaction, decreased customer spending levels, decreased customer transaction volumes, increased competition, changes in tax laws or rules, pricing changes or legislative changes affecting tax compliance providers. If our customers do not renew their subscriptions, or our customers reduce the solutions purchased under their subscriptions, our revenue would decline and our business may be harmed.

        Our future success also depends in part on our ability to sell additional solutions to existing customers and on our customers' expanded use of our solutions. If our efforts to sell our additional solutions to our customers are not successful or if our customers do not expand their use of our solutions, it would decrease our revenue growth and harm our business, results of operations, financial condition and cash flows.

Our business and success depend in part on our strategic relationships with third parties, including our partner ecosystem, and our business would be harmed if we fail to maintain or expand these relationships.

        We depend in part on, and anticipate that we will continue to depend in part on, various third-party relationships to sustain and grow our business. Our relationships with third-party publishers of software business applications, including accounting, ERP, eCommerce, POS, recurring billing and CRM systems, help drive our business because the integration of our solutions with their applications allows us to reach their sizeable customer bases. Our customers' user experience is dependent on our ability to connect easily to such third-party software applications. We may fail to retain and expand these integrations or relationships for many reasons, including due to failures by third parties to maintain, support or secure their technology platforms in general and our integrations in particular, or errors, bugs or defects in such third party technology, or changes in our technology platform. Any such failure could harm our relationship with our customers, our reputation and brand and our business and results of operations.

        In addition, integrating third-party technology can be complex, costly and time-consuming. Third parties may be unwilling to build integrations, and we may be required to devote additional resources to develop integrations for business applications on our own. Providers of business applications with which we have integrations may decide to compete with us or enter into arrangements with our competitors, resulting in such providers withdrawing support for our integrations. In addition, any failure of our solutions to operate effectively with business applications could reduce the demand for

18


Table of Contents

our solutions, resulting in customer dissatisfaction and harm to our business. If we are unable to respond to these changes or failures in a cost-effective manner, our solutions may become less marketable, less competitive or obsolete and our results of operations may be negatively impacted.

If we are unable to adapt to technological change by successfully introducing new and enhanced solutions and services, our business, results of operations, financial condition and cash flows would be adversely affected.

        The market for our solutions is characterized by rapid technological change, frequent new product and service introductions and enhancements, changing customer demands and evolving industry standards. The introduction of software embodying new technologies can quickly make existing software obsolete and unmarketable. Software solutions are inherently complex, and it can take a long time and require significant research and development expenditures to develop and test new or enhanced solutions. The success of any enhancements or improvements to our software solutions or any new solutions and services depends on several factors, including timely completion, competitive pricing, adequate quality testing, integration with existing technologies and our platform and overall market acceptance. We cannot be sure that we will succeed in developing, marketing and delivering on a timely and cost-effective basis enhancements or improvements to our software or any new solutions and services that respond to technological change or new customer requirements, nor can we be sure that any enhancements or improvements to our software or any new solutions and services will be free of errors and defects or that they will achieve market acceptance. Moreover, even if we introduce new solutions, we would experience a decline in revenue of our existing solutions that is not offset by revenue from the solutions. Customers may delay making purchases of new solutions to permit them to make a more thorough evaluation of these solutions or until industry and marketplace reviews become widely available. In addition, we may lose existing customers who choose a competitor's solutions rather than migrate to our new solutions. This could result in a temporary or permanent revenue shortfall and adversely affect our business.

Any failures in information technology or infrastructure could lead to disruptions of our software, loss of customer data or untimely remittance of taxes, any of which could adversely affect our reputation and financial condition.

        Our software depends on uninterrupted, high-speed access to the internet in order to provide real-time tax determinations and processing of indirect tax data. Failures in our or our customers' and partners' information technology and infrastructure or service outages at third-party internet providers could lead to disruptions to our software. Such failures may be caused by numerous factors, including mechanical failure, power outage, human error, physical or electronic security breaches, war, terrorism, fire, earthquake, hurricane, flood and other natural disasters, sabotage and vandalism. Disruptions to our software could cause customers to lose sensitive or confidential information and could also lead to our or our customers' inability to timely remit taxes to the appropriate authorities. Any of these outcomes could lead customers to switch to our competitors or avoid using our solutions, which would negatively impact our revenue and harm our opportunities for growth.

Incorrect or improper implementation, integration or use of our solutions could result in customer dissatisfaction and negatively affect our business, results of operations, financial condition and cash flows.

        Our customers may need training or education in the proper use of, and the variety of benefits that can be derived from, our solutions to maximize their potential benefits. If our solutions are not implemented or used correctly or as intended, inadequate performance may result. Because our customers rely on our solutions to manage a wide range of tax compliance operations, the incorrect or improper implementation or use of our solutions, or our failure to provide adequate support to our customers, may result in negative publicity or legal claims against us, which could harm our business, results of operations, financial condition and cash flows. Also, as we continue to expand our customer

19


Table of Contents

base, any failure by us to properly provide training and support will likely result in lost opportunities for additional subscriptions for our solutions.

If we fail to attract and retain qualified technical and tax-content personnel, our business could be harmed.

        Our technology is complex and our success depends in large part on our ability to attract and retain highly qualified personnel, particularly tax-content specialists, software developers, technical support and research and development personnel. Competition for skilled personnel is intense and we may not be successful in attracting, motivating and retaining needed personnel. We also may be unable to attract or integrate into our operations qualified personnel on the schedule we desire. Any inability to attract, integrate, motivate and retain the necessary personnel could harm our business. Dealing with the loss of the services of our executive officers or key personnel and the process to replace any of our executive officers or key personnel may involve significant time and expense, take longer than anticipated, and significantly delay or prevent the achievement of our business objectives, which would harm our financial condition, results of operations, and business.

We face competitive pressures from other tax software and services providers, as well as the challenge of convincing businesses using manual processes and native ERP functions to switch to our software.

        We face significant competitive challenges from other tax-specific software vendors and from outsourced transaction tax compliance services offered by accounting and specialized consulting firms. There are a number of competing tax-specific software vendors, some of which have substantially greater revenue, personnel and other resources than we do. Corporate competitors, as well as the state and local tax services offered by accounting firms, have historically targeted our customer base of large enterprise companies. In addition, our competitors who currently focus their tax compliance services on small- to medium-sized businesses may be better positioned to increase their market share with small- to medium-sized businesses and may choose to enter our markets, whether competing based on price, service or otherwise. We also face a growing number of competing private transaction tax compliance businesses focused primarily on eCommerce. Increased competition may impact our ability to add new customers and to retain and expand revenues from existing customers. It is also possible that large enterprises with substantial resources that operate in adjacent compliance, finance or eCommerce verticals may decide to pursue transaction tax compliance automation and become immediate, significant competitors. Our failure to successfully and effectively compete with current or future competitors could lead to lost business and negatively affect our revenue.

        In addition, many companies continue to employ manual processes that often rely on transaction-specific research, static tax tables, non-tax specific software or rate calculator services, as well as manual filing and remittance activities. Many businesses using manual approaches believe that these processes are adequate and may be unaware that there is an alternative that is more effective, resulting in an inertia that can be difficult to overcome. In addition, the upfront costs of our solutions can limit our sales to businesses using manual processes.

Our recent success may not be indicative of our future results of operations.

        We cannot predict with certainty our customers' future usage or retention given the diversity of our customer base across industries, geographies, customer size and other factors. Accordingly, we may be unable to accurately forecast our revenues notwithstanding our substantial investments in sales and marketing, tax content infrastructure and research and development in anticipation of continued growth in our business. If we do not realize returns on these investments in our growth, our results of operations could differ materially from our prior results, which could cause our stock price to decline.

We currently derive a substantial portion of our revenue from our indirect tax software, and any failure of our software to satisfy customer requirements or to achieve increased market penetration could adversely affect our business, results of operations, financial condition and growth prospects.

        We currently derive a substantial portion of our revenue from subscriptions to our indirect tax software. We have added, and will continue to add, additional solutions to expand our offerings, but, at least in the near term, we expect to continue to derive the majority of our revenue from our indirect tax software. As such, the ability of our indirect tax software to meet our customers' requirements is critical to our success. Demand for our solutions is affected by a number of factors, many of which are beyond our control, such as continued market acceptance and continued employment of our solutions by existing and new customers, the timing of the development and release of upgraded or new solutions, the introduction or upgrading of products and services by our competitors, technological change and growth or contraction in our addressable market. If our indirect tax software does not continue to meet customer requirements, our business, results of operations, financial condition and growth prospects will suffer.

Changes to customers' and partners' software systems may impact our ability to offer a specific software deployment method to existing customers, which could cause a termination of customer contracts utilizing that deployment method, or otherwise effect our results of operations, financial condition and cash flow.

        Our solutions are integrated with the software systems and complex workflows of our customers and partners. In the event that such software systems are modified or updated in a way that is incompatible with our software, we may be unable to continue to support the operations of our customers and partners. If our customers are unable to implement our solutions successfully or in a timely manner, or if our partners are unable to integrate with our solutions through our integrations, customer perceptions of our solutions may be impaired, our reputation and brand may suffer and customers may choose not to renew or expand the use of our solutions. In addition, if we fail to anticipate technological changes that our customers and partners may look to adopt, our solutions may be perceived as being less effective or obsolete. Any of these changes could have a material adverse effect on our results of operations and financial condition.

We need to continue making significant investments in software development and equipment to improve our business.

        To improve the scalability, security and efficiency of our solutions, and to support the expansion of our software into other tax types, we will need to continue making significant capital expenditures and also invest in additional software and infrastructure development. If we experience increasing demand in subscriptions, we may not be able to augment our infrastructure quickly enough to accommodate such increasing demand. In the event of decreases in subscription sales, certain of our fixed costs, such as for capital expenditures, may make it difficult for us to quickly adjust our expenses downward. Additionally, we are continually updating our software and content, which increases expenses for us. We may also need to review or revise our software architecture as we grow, which may require significant resources and investments. As a result, although we may have significant research and development expenditures, which may be incurred and certain of which may be capitalized, there is no guarantee our solutions will be accepted by the market. This could result in increased costs or an impairment of capitalized development costs with no resulting future revenue benefit.

Our continued growth depends in part on our ability to continue to grow our customer base.

        Increasing our customer base will depend, to a significant extent, on our ability to effectively expand our sales and marketing activities, as well as our partner ecosystem and other customer referral sources. We may not be able to recruit qualified sales and marketing personnel, train them to perform and achieve an acceptable level of sales production from them on a timely basis or at all. In the past, it

21


Table of Contents

has usually taken new members of our sales force at least six months to integrate into our operations and start converting sales leads at our expected levels. In addition, if we cannot continue to maintain or expand our relationships with our partners, we may receive fewer referrals, the set of integrations we offer may not keep up with the market and our customer expansion strategy may become less effective. If we are unable to maintain effective sales and marketing activities and maintain and expand our partner network, our ability to attract new customers could be harmed and our business, results of operations, financial condition and cash flows would suffer.

If we fail to effectively manage our growth, our business, results of operations, financial condition and cash flows will be harmed.

        We have experienced, and may continue to experience, growth in our headcount and operations, both domestically and internationally, which has placed, and may continue to place, significant demands on our management and our administrative, operational and financial reporting resources. We have also experienced significant growth in the number of customers, number of transactions and the amount of tax content that our platform and solutions support. Our growth will require us to hire additional employees and make significant expenditures, particularly in sales and marketing but also in our technology, professional services, finance and administration teams, as well as in our facilities and infrastructure. Our ability to effectively manage our growth will also require the allocation of valuable management and employee resources and improvements to our operational and financial controls and our reporting procedures and systems. In addition, as we seek to continue to expand internationally, we will likely encounter unexpected challenges and expenses due to unfamiliarity with local requirements, practices and markets. Our expenses may increase more than we plan, and we may fail to hire qualified personnel, expand our customer base, enhance our existing solutions, develop new solutions, integrate any acquisitions, satisfy the requirements of our existing customers, respond to competitive challenges or otherwise execute our strategies. If we are unable to effectively manage our growth, our business, results of operations, financial condition and cash flows would likely be harmed.

Future acquisitions of, and investments in, other businesses, software, tax content or technologies may not yield expected benefits, and our inability to successfully integrate acquisitions may negatively impact our business, results of operations, financial condition and cash flows.

        We may in the future seek to grow our operations by pursuing acquisitions of businesses, software and technologies. We may not realize the anticipated benefits, or any benefits, from future acquisitions. In addition, if we finance acquisitions by incurring debt or by issuing equity or convertible or debt securities, our existing stockholder may be diluted or we could face constraints related to covenants in the agreements governing the indebtedness, which could affect the market value of our capital stock. To the extent that the acquisition consideration is paid in the form of an earnout on future financial results, the success of such an acquisition will not be fully realized by us for a period of time as it is shared with the sellers. Further, if we fail to properly evaluate and execute acquisitions or investments, our business and prospects may be seriously harmed and the value of your investment may decline. For us to realize the benefits of future acquisitions, we must successfully integrate the acquired businesses, software or technologies with ours. This may take time and divert management's attention from our day-to-day operations, which could negatively impact our business, results of operations, financial condition and cash flows.

Our quarterly and annual results of operations will fluctuate in future periods.

        We will experience quarterly or annual fluctuations in our results of operations due to a number of factors, many of which are outside of our control. This makes our future results difficult to predict and

22


Table of Contents

could cause our results of operations to fall below expectations or our predictions. Factors that might cause quarterly or annual fluctuations in our results of operations include:

        Any one of the factors above, or the cumulative effect of some or all of the factors referred to above, may result in significant fluctuations in our quarterly and annual results of operations. This variability and unpredictability could result in our failure to meet or exceed our internal operating plan. In addition, a percentage of our operating expenses is fixed in nature and is based on forecasted financial performance. In the event of revenue shortfalls, we may not be able to mitigate the negative impact on our results of operations quickly enough to avoid short-term impacts.

        We generally recognize revenue from subscription fees paid by customers ratably over the subscription term. As a result, most of the subscription revenue we report in each quarter is the result of agreements entered into during previous quarters. Consequently, a decline in new or renewed subscriptions in any one quarter will not be fully reflected in our revenue results for that quarter. Any such decline, however, will negatively affect our revenue in future quarters. Our subscription model also makes it difficult for us to rapidly increase our revenue through additional sales in any period, as subscription revenue from new customers is generally recognized over the applicable subscription terms.

Operating globally involves challenges that may adversely affect our ability to grow.

        We plan to continue expanding our business operations globally and to enter new markets where we have limited or no experience in marketing, selling and deploying our solutions. If we fail to deploy or manage our operations in international markets successfully, our business may suffer. In the future, as our international operations increase, or more of our expenses are denominated in currencies other than the U.S. dollar, our results of operations may become more sensitive to fluctuations in the

23


Table of Contents

exchange rates of the currencies in which we do business. In addition, we are subject to a variety of risks inherent in doing business internationally, including:

        If we are unable to expand internationally and manage the complexity of our global operations successfully, our business could be seriously harmed.

We hold significant amounts of money that we remit to taxing authorities on behalf of our customers, and this may expose us to liability from errors, delays, fraud or system failures, which may not be covered by insurance.

        We handle significant amounts of our customers' money so that we can remit those amounts to various taxing jurisdictions on their behalf. If we make mistakes in the determination or remittance of tax payments to the appropriate jurisdictions, our reputation and results of operations could suffer. Moreover, if our banks' or our own internal compliance procedures regarding cash management fail, are hacked or sabotaged, or if our banks or we are the subject of fraudulent behavior by personnel or third parties, we could face significant financial losses. Our efforts to remit tax payments to applicable taxing jurisdictions after receiving the corresponding funds from our customers may fail, which would

24


Table of Contents

expose us to the financial risk of collecting from our customers after we have remitted funds on their behalf.

        Additionally, we are subject to risk from concentration of cash and cash equivalent accounts, including cash from our customers that is to be remitted to taxing jurisdictions, with financial institutions where deposits routinely exceed federal insurance limits. If the financial institutions in which we deposit our customers' cash were to experience insolvency or other financial difficulty, our access to cash deposits could be limited, any deposit insurance may not be adequate, we could lose our cash deposits entirely and we could be exposed to liability to our customers. Any of these events would negatively impact our liquidity, results of operations and our reputation.

If we are unable to successfully adapt to organizational changes and effectively implement strategic initiatives, our reputation and results of operations could be impacted.

        We have a dynamic organization and routinely implement changes to our priorities and workforce in order to keep up with the constantly evolving market in which we operate. We expect these types of changes to continue for the foreseeable future. Successfully managing these changes, including retention of key employees, is critical to our business success. In addition, we are generally a build-from-within company, and our success is dependent on identifying, developing and retaining key employees to provide uninterrupted leadership and direction for our business. This includes developing organizational capabilities in key growth markets where the depth of skilled employees is limited and competition for these resources is intense. Further, business and organizational changes may result in more reliance on third parties for various services, and that reliance may increase reputational, operational and compliance risks.

Errors in our customers' transaction tax determinations and reporting functions, or delays in the remittance of their tax payments, could harm our reputation, results of operations and growth prospects.

        The tax determinations functions that our customers have to perform are complicated from a data management standpoint, time-sensitive and dependent on the accuracy of the database of tax content underlying our solutions. Some of our processes are not fully automated, such as our process for monitoring updates to tax rates and rules, and even to the extent our processes are automated, our solutions are not proven to be without any possibility of errors. If errors are made in our customers' tax determinations and reporting functions, or delays occur in the remittance of their tax payments, our customers may be assessed interest and penalties. Although our agreements generally have disclaimers of warranties and limit our liability, a court could determine that such disclaimers and limitations are unenforceable as a matter of law and hold us liable for these errors. Additionally, erroneous tax determinations could result in overpayments to taxing authorities that are difficult to reclaim from the applicable taxing authorities or underpayments that could result in penalties. Any history of erroneous tax determinations for our customers could also harm our reputation, could result in negative publicity, loss of or delay in market acceptance of our solutions, loss of customer renewals and loss of competitive position. In addition, our insurance coverage may not cover all amounts claimed against us if such errors or failures occur. The financial and reputational costs associated with any erroneous tax determinations may be substantial and could harm our results of operations.

Changes in tax laws and regulations, or their interpretation or enforcement, may cause us to invest substantial amounts to modify our software, cause us to change our business model or draw new competitors to the market.

        Changes in tax laws or regulations or interpretations of existing taxation requirements in the United States or in other countries may require us to change the manner in which we conduct some aspects of our business and could harm our ability to attract and retain customers. For example, a material portion of our revenue is generated by performing what can be complex transaction tax

25


Table of Contents

determinations and the corresponding preparation of tax returns and remittance of taxes. Changes in tax laws or regulations that reduce complexity or decrease the frequency of tax filings could negatively impact our revenue. In addition, there is considerable uncertainty as to if, when and how tax laws and regulations might change. As a result, we may need to invest substantial funds to modify our solutions to adapt to new tax laws or regulations. If our software solutions are not flexible enough to adapt to changes in tax laws and regulations, our financial condition and results of operations may suffer.

        A number of states have considered or adopted laws that attempt to require out-of-state retailers to collect sales taxes on their behalf or to provide the jurisdiction with information enabling it to more easily collect use tax. On June 21, 2018, the U.S. Supreme Court issued its opinion in South Dakota v. Wayfair, Inc., upholding South Dakota's economic nexus law, which requires certain out-of-state retailers to collect and remit sales taxes on sales into South Dakota. Following the Supreme Court's decision, certain states with pre-existing economic nexus provisions announced that they would begin enforcing these provisions on out-of-state retailers and additional states have proceeded with similar efforts. There also has been consideration of federal legislation related to taxation of interstate sales, which, if enacted into law, would place guidelines or restrictions on states' authority to require online and other out of state merchants to collect and remit indirect tax on products and services that they may sell. Similar issues exist outside of the United States, where the application of value-added taxes or other indirect taxes on online retailers is uncertain and evolving. The effect of changes in tax laws and regulations is uncertain and dependent on a number of factors. Depending on the content of any indirect tax legislation, the role of third-party compliance vendors may change, we may need to invest substantial amounts to modify our solutions or our business model, we could see a decrease in demand, we could see new competitors enter the market, or we could be negatively impacted by such legislation in a way not yet known.

We are exposed to cybersecurity and data privacy risks that, if realized, could expose us to legal liability, damage our reputation and harm our business.

        We face risks of cyber-attacks, computer hacks, theft, viruses, malicious software, phishing, employee error, denial-of-service attacks and other security breaches that could jeopardize the performance of our software and expose us to financial and reputational harm. Any of these occurrences could create liability for us, put our reputation in jeopardy and harm our business. Such harm could be in the form of theft of our or our customers' confidential information, the inability of our customers to access our systems or the improper re-routing of customer funds through fraudulent transactions or other frauds perpetrated to obtain inappropriate payments. In some cases, we rely on the safeguards put in place by third parties to protect against security threats. These third parties, including vendors that provide products and services for our operations, could also be a source of security risk to us in the event of a failure or a security incident affecting their own security systems and infrastructure. Our network of ecosystem partners could also be a source of vulnerability to the extent their applications interface with ours, whether unintentionally or through a malicious backdoor. We do not review the software code included in third-party integrations in all instances. Because the techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized until launched against a target, we or these third parties may be unable to anticipate these techniques or to implement adequate preventative measures. We have internal controls designed to prevent cyber-related frauds related to authorizing the transfer of funds, but such internal controls may not be adequate. With the increasing frequency of cyber-related frauds to obtain inappropriate payments and other threats related to cyber-attacks, we may find it necessary to expend resources to remediate cyber-related incidents or to enhance and strengthen our cybersecurity. Our remediation efforts may not be successful and could result in interruptions, delays or cessation of service. Although we have insurance coverage for losses associated with cyber-attacks, as with all insurance policies, there are coverage exclusions and limitations, and our coverage may not be sufficient to cover all possible

26


Table of Contents

claims, and we may still suffer losses that could have a material adverse effect on our reputation and business.

        Our customers provide us with information that our solutions store, some of which may be confidential information about them or their financial transactions. In addition, we store personal information about our employees and, to a lesser extent, those who purchase products or services from our customers. We have security systems and information technology infrastructure designed to protect against unauthorized access to such information. The security systems and infrastructure we maintain may not be successful in protecting against all security breaches and cyber-attacks, social-engineering attacks, computer break-ins, theft and other improper activity. Threats to our information technology security can take various forms, including viruses, worms and other malicious software programs that attempt to attack our solutions or platform or to gain access to the data of our customers or their customers. Like other companies, we have on occasion and will continue to experience threats to our data and systems. Any significant data breach could result in the loss of business, litigation and regulatory investigations, loss of customers and fines and penalties that could damage our reputation and brand and adversely affect the growth of our business.

We may become involved in material legal proceedings and audits, the outcomes which could adversely affect our business, results of operations, financial condition and cash flows.

        From time to time, we are involved in claims, suits, investigations, audits and proceedings arising in the ordinary course of our business, and we may in the future become involved in legal proceedings and audits that could have a material adverse effect on our business, results of operations, financial condition and cash flows. Claims, suits, investigations, audits and proceedings are inherently difficult to predict and their results are subject to significant uncertainties, many of which are outside of our control. Regardless of the outcome, such legal proceedings could have a negative impact on us due to legal costs, diversion of management resources and other factors. In addition, it is possible that a resolution of one or more such proceedings could result in reputational harm, substantial settlements, judgments, fines or penalties, criminal sanctions, consent decrees or orders preventing us from offering certain features, functionalities, products or services, requiring us to change our development process or other business practices.

        There is also inherent uncertainty in determining reserves for these matters. There is significant judgment required in the analysis of these matters, including assessing the probability of potential outcomes and determining whether a potential exposure can be reasonably estimated. Further, it may take time to develop factors on which reasonable judgments and estimates can be based. If we fail to establish appropriate reserves, our business could be negatively impacted.

Undetected errors, bugs or defects in our software could harm our reputation or decrease market acceptance of our software, which would harm our business and results of operations.

        Our software may contain undetected errors, bugs or defects. We have experienced these errors, bugs or defects in the past in connection with new software and software upgrades and we expect that errors, bugs or defects may be found from time to time in the future in new or enhanced software after their commercial release. Our software is often used in connection with large-scale computing environments with different operating systems, system management software, equipment and networking configurations, which may cause or reveal errors or failures in our software or in the computing environments in which they are deployed. Despite testing by us, errors, bugs or defects may not be found in our software until they are used by our customers. In the past, we have discovered errors, bugs and defects in our software after they have been deployed to customers.

        Any errors, bugs, defects, disruptions in service or other performance problems with our software may damage our customers' businesses and could hurt our reputation, brand and business. We may also

27


Table of Contents

be required, or may choose, for customer relations or other reasons, to expend additional resources to correct actual or perceived errors, bugs or defects in our software. If errors, bugs or defects are detected or perceived to exist in our software, we may experience negative publicity, loss of competitive position or diversion of the attention of our key personnel, our customers may delay or withhold payment to us or elect not to renew their subscriptions, or other significant customer relations problems may arise. We may also be subject to liability claims for damages related to errors, bugs or defects in our software. A material liability claim or other occurrence that harms our reputation or decreases market acceptance of our software may harm our business and results of operations.

Our software utilizes open-source software, and any defects or security vulnerabilities in the open-source software could negatively affect our business.

        Certain of our software employs open-source software and we expect to use open-source software in the future. To the extent that our software depends upon the successful operation of open-source software, any undetected errors or defects in this open-source software could prevent the deployment or impair the functionality of our software, delay the introduction of new solutions, result in a failure of our software, and injure our reputation. For example, undetected errors or defects in open source software could render it vulnerable to breaches or security attacks, and, in conjunction, make our systems more vulnerable to data breaches.

        In addition, the terms of various open-source licenses have not been interpreted by United States courts, and there is a risk that such licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to market certain of our software solutions. Some open-source licenses might require us to make our source code available for no cost, to make publicly available source code for modifications or derivative works that we create based upon, incorporating or using the open source software, and/or to license such modifications or derivative works under the terms of the particular open source license. While we try to insulate our proprietary code from the effects of such open-source license provisions, we cannot guarantee we will be successful. In addition to risks related to open-source license requirements, usage of open-source software can lead to greater risks than use of third-party commercial software, as open-source licensors generally do not provide warranties or controls on the origin of the software. Many of the risks associated with usage of open-source software cannot be eliminated and could negatively affect our business, financial condition and results of operations.

We rely on third-party data centers, systems and technologies to operate our business, and interruptions or performance problems with these third-party providers may adversely affect our business and results of operations.

        We rely on data centers and other technologies and services provided by third parties in order to operate our business. If any of these services becomes unavailable or otherwise is unable to serve our requirements, there could be interruptions to our software and provision of services to our customers. Our business depends on our ability to protect the growing amount of information stored in data centers and related systems, offices and hosting facilities against damage from earthquakes, floods, fires, other extreme weather conditions, power loss, telecommunications failures, hardware failures, viruses, terrorist attacks, acts of war, unauthorized electronic or physical intrusion, overload conditions and other events. If our data centers or related systems fail to operate properly or become disabled even for a brief period of time, we could suffer financial loss, a disruption of our business, liability to customers or damage to our reputation. Our response to any type of disaster may not be successful in preventing the loss of customer data, service interruptions, disruptions to our operations or damage to our important facilities. Our data center providers have no obligations to renew their agreements with us on commercially reasonable terms, or at all, and it is possible that we will not be able to switch our operations to another provider in a timely and cost-effective manner should the need arise. If we are unable to renew our agreements with these providers on commercially reasonable terms, or if in the future we add additional data center facility providers, we may face additional costs or expenses or downtime, which could harm our business.

        We also rely on computer hardware purchased or leased from, software licensed from, content licensed from and services provided by a variety of third parties, which include database, operating system, virtualization software, tax requirement content and geolocation content and services. Any errors, bugs or defects in such third-party hardware, software, content or services could result in errors or a failure of our solutions, which could harm our business. In the future, we might need to license other hardware, software, content or services to enhance our solutions and meet evolving customer requirements. Any inability to license or otherwise obtain such hardware or software could result in a reduction in functionality, or errors or failures of our products, until equivalent technology is either developed by us or, if available, is identified, obtained through purchase or license, and integrated into our solutions, any of which may reduce demand for our solutions and increase our expenses. In addition, third-party licenses may expose us to increased risks, including risks associated with the integration of new technology, the diversion of resources from the development of our own proprietary technology, and our inability to generate revenue from new technology sufficient to offset associated acquisition and maintenance costs, all of which may increase our expenses and harm our results of operations.

If we fail to effectively protect, maintain and enhance our brand, our business may suffer.

        As a leader in our industry for over 40 years, our brand is one of our most valuable assets, and any failure to protect our brand could cause our business to suffer. In addition, the promotion of our brand requires us to make substantial expenditures, and we anticipate that the expenditures will increase as our market becomes more competitive and as we expand into new regions. The demand for and cost of online and traditional advertising have been increasing and may continue to increase. Our brand promotion efforts will require investment not just in our indirect tax solutions, but also in our full suite of software and services. To the extent that these activities yield increased revenue, this revenue may not offset the increased expenses we incur. If we do not successfully maintain and enhance our brand, our business may not grow, we may have reduced pricing power relative to competitors and we could lose customers or fail to attract potential new customers, all of which would adversely affect our business, results of operations, financial condition and cash flows.

Changes in the application, scope, interpretation or enforcement of laws and regulations pertaining to our operations may harm our business or results of operations, subject us to liabilities and require us to implement new compliance programs or business methods.

        We perform a number of critical business functions for our customers, including remittance of the taxes our customers owe to taxing authorities. Our electronic payment of customers' taxes may be subject to federal or state laws or regulations relating to money transmission. The Federal Bank Secrecy Act requires that financial institutions, of which money transmitters are a subset, register with the U.S. Department of Treasury's Financial Crimes Enforcement Network and maintain policies and procedures reasonably designed to monitor, identify, report and, where possible, avoid money laundering and criminal or terrorist financing by customers. Most U.S. states also have laws that apply to money transmitters, and impose various licensure, examination and bonding requirements on them. We believe these federal and state laws and regulations were not intended to cover the business activity of remitting transaction taxes that taxpayers owe to the various states and localities. However, if federal or state regulators were to apply these laws and regulations to this business activity, whether through expansion of enforcement activities, new interpretations of the scope of certain of these laws or regulations or of available exemptions, or if our activities are held by a court to be covered by such laws or regulations, we could be required to expend time, money and other resources to deal with enforcement actions and any penalties that might be asserted, to institute and maintain a compliance program specific to money transmission laws, and possibly to change aspects of how we conduct our business to achieve compliance or minimize regulation. Application of these laws to our business could also make it more difficult or costly for us to maintain our banking relationships. Financial institutions may also be unwilling to provide banking services to us due to concerns about the large dollar volume

moving in and out of our accounts on behalf of our customers in the ordinary course of our business. As we continue to expand the solutions we offer and the jurisdictions in which we offer them, we could become subject to other licensing, examination or regulatory requirements relating to financial services.

        Determining the taxes owed by our customers involves providing solutions tailored to the types and prices of products our customers sell, as well as information regarding addresses that products are shipped from and delivered to. Numerous federal, state and local laws and regulations govern the collection, dissemination, use and safeguarding of personal information and other data, the scope of which is changing, subject to differing interpretations, and which may be costly to comply with, inconsistent between jurisdictions or conflicting with other rules. We may be subject to these laws in certain circumstances. Most states have also adopted laws that require notice be given to affected consumers in the event of a security breach. In the event of a security breach, our compliance with these laws may subject us to costs associated with notice and remediation, as well as potential investigations from federal regulatory agencies and state attorneys general. A failure on our part to safeguard consumer data adequately or to destroy data securely may subject us, depending on the personal information in question, to costs associated with notice and remediation, as well as to potential regulatory investigations or enforcement actions, and possibly to civil liability, under federal or state data security or unfair practices or consumer protection laws. If federal or state regulators were to expand their enforcement activities, or change their interpretation of the applicability of these laws, or if new laws regarding privacy and protection of consumer data were to be adopted, the burdens and costs of complying with them could increase significantly, negatively affecting our results of operations and possibly the manner in which we conduct our business. For example, the European Union's General Data Protection Regulation requires certain operational changes for companies that receive or process personal data of residents of the EU and includes significant penalties for noncompliance. In addition, other governmental authorities around the world are considering implementing similar types of legislative and regulatory proposals concerning data protection. We may incur significant costs to comply with these mandatory privacy and security standards.

If economic conditions worsen, it may negatively affect our business and financial performance.

        Our financial performance depends, in part, on the state of the economy, both in the United States and globally. Declining levels of economic activity may lead to declines in spending and customer revenue, which may result in decreased revenue for us. Concern about the strength of the economy may slow the rate at which businesses of all sizes are willing to hire an outside vendor to perform the determination and remittance of their transaction taxes and filing of related returns. If our customers and potential customers experience financial hardship as a result of a weak economy, industry consolidation or other factors, the overall demand for our solutions could decrease. If economic conditions worsen, our business, results of operations, financial condition and cash flows could be harmed.

Natural disasters, epidemic outbreaks, terrorist acts and political events could disrupt business and result in lower sales and otherwise have a material adverse effect on our business, financial performance and results of operations.

        The occurrence of one or more major natural disasters, unusual weather conditions, epidemic outbreaks, terrorist attacks or disruptive political events, each of which is out of our control, may result in reduced consumer and supplier spending and transactions, which in turn could cause our revenues to decline and our business to suffer. Natural disasters including tornados, hurricanes, floods and earthquakes may damage the facilities of our customers or those of their suppliers or retailers or their other operations, which could lead to reduced revenue for our customers and thus less transaction tax due. In addition, a global epidemic outbreak may have a material adverse effect on global economic conditions, consumer spending and the stability of global financial markets. For example, in December 2019, a novel strain of coronavirus ("COVID-19") appeared. The COVID-19 pandemic is having

30


Table of Contents

widespread, rapidly evolving and unpredictable impacts on global society, economies, financial markets and business practices. Federal and state governments have implemented measures in an effort to contain the virus, including social distancing, travel restrictions, border closures, limitations on public gatherings, work-from-home, supply chain logistical changes and closure of non-essential businesses. To protect the health and well-being of our employees and customers, we have made substantial modifications to employee travel policies, closed our offices as employees are advised to work-from-home and cancelled or shifted our conferences and other marketing events to virtual-only. The COVID-19 pandemic has impacted and may continue to adversely impact our business operations, including our employees, customers and partners, and there is substantial uncertainty in the nature and degree of its continued effects over time. The extent to which the COVID-19 pandemic impacts our business going forward will depend on numerous evolving factors that we cannot reliably predict, including (i) the duration and scope of the pandemic; (ii) actions of governments, businesses and individuals in response to the pandemic and (iii) the impact on economic activity including the possibility of recession or financial market instability. These factors may adversely impact consumer and business spending as well as customers' ability to pay for our software and solutions on an ongoing basis. Similarly, terrorist attacks or disruptive political events, such as the imposition of retaliatory tariffs or governmental trade or price manipulation, could cause our customers, or their customers, to defer spending plans or otherwise reduce their economic activity. If any of the foregoing risks were to be realized, it could have a material adverse effect on or business, financial performance and results of operations.

We are subject to anti-corruption, anti-bribery and similar laws and noncompliance with such laws can subject us to criminal penalties or significant fines and harm our business and reputation.

        We are subject to requirements under the U.S. Treasury Department's Office of Foreign Assets Control, anti-corruption, anti-bribery and similar laws, such as the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, the U.K. Bribery Act 2010, and other anti-corruption, anti-bribery and anti-money laundering laws in countries in which we conduct activities. Anti-corruption and anti-bribery laws have been enforced aggressively in recent years and are interpreted broadly and prohibit companies and their employees and agents from promising, authorizing, making, offering or providing anything of value to a "foreign official" for the purposes of influencing official decisions or obtaining or retaining business, or otherwise obtaining favorable treatment. As we increase our international operations, our risks under these laws may increase. Non-compliance with these laws could subject us to investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, adverse media coverage and other consequences. Any investigations, actions or sanctions could harm our business, results of operations, financial condition and cash flows.

        In addition, in the future we may use third parties to sell access to our software and conduct business on our behalf abroad. We or such future third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities, and we can be held liable for the corrupt or other illegal activities of such future third-party intermediaries, and our employees, representatives, contractors, partners and agents, even if we do not explicitly authorize such activities. We cannot provide assurance that our internal controls and compliance systems will always protect us from liability for acts committed by employees, agents or business partners of ours (or of businesses we acquire or partner with) that would violate U.S. and/or non-U.S. laws, including the laws governing payments to government officials, bribery, fraud, kickbacks, false claims, pricing, sales and marketing practices, conflicts of interest, competition, employment practices and workplace behavior, export and import compliance, economic and trade sanctions, money laundering, data privacy and other related laws. Any such improper actions or allegations of such acts could subject us to significant sanctions, including civil or criminal fines and penalties, disgorgement of

31


Table of Contents

profits, injunctions and debarment from government contracts, as well as related stockholder lawsuits and other remedial measures, all of which could adversely affect our reputation, business, results of operations and financial condition.

        Any violation of economic and trade sanction laws, export and import laws, the FCPA or other applicable anti-corruption laws or anti-money laundering laws could also result in whistleblower complaints, adverse media coverage, investigations and severe criminal or civil sanctions, any of which could have a materially adverse effect on our reputation, business, results of operations and prospects.

Our ability to protect our intellectual property is limited, and we may be subject to claims of infringement by third parties.

        Our success depends, in part, upon our proprietary technology, processes, trade secrets, and other proprietary information and our ability to protect this information from unauthorized disclosure and use. We primarily rely upon a combination of copyright, trademark and trade secret laws, as well as confidentiality procedures, contractual provisions and other similar measures to protect our proprietary or confidential information and intellectual property. Our trademarks and service marks include VERTEX™ and O Series™, which is our flagship indirect tax solution. Despite our efforts to protect our proprietary rights and intellectual property, unauthorized parties may attempt to copy aspects of our solutions or to obtain and use information that we regard as proprietary, and third parties may attempt to independently develop similar technology, and policing unauthorized use of our technology and intellectual property rights may be difficult and may not be effective.

        In addition, third parties may claim infringement by us with respect to current or future solutions or other intellectual property rights. The software and technology industries are characterized by the existence of a large number of patents, trademarks and copyrights and by frequent litigation based on allegations of infringement or other violations of intellectual property rights. The outcome of any claims or litigation, regardless of the merits, is inherently uncertain. Any claims and lawsuits to enforce our intellectual property rights or to defend ourselves against claims of infringement of third-party intellectual property rights, and the disposition of such claims and lawsuits, whether through settlement or licensing discussions, or litigation, could be time-consuming and expensive to resolve, divert management attention from executing our strategies, result in efforts to enjoin our activities, lead to attempts on the part of other parties to pursue similar claims, and, in the case of intellectual property claims, require us to change our technology, change our business practices, pay monetary damages, or enter into short- or long-term royalty or licensing agreements. Any adverse determination related to intellectual property claims or other litigation could prevent us from offering our solutions to others, could be material to our financial condition or cash flows, or both, or could otherwise harm our results of operations.

Our ability to obtain additional capital on commercially reasonable terms may be limited.

        We intend to continue to make investments to support our business growth and may require additional funds, beyond those generated by this offering, to respond to business challenges, including to better support and serve our customers, develop new software or enhance our existing solutions, improve our operating and technology infrastructure or acquire complementary businesses and technologies. Accordingly, we may need to engage in public or private equity, equity-linked or debt financings to secure additional funds. If we raise additional funds through future issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our Class A common stock. Any debt financing that we secure in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, including the ability to pay dividends. This may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. We may not be able to obtain additional financing on terms favorable to us, if at all. If we are unable to obtain adequate financing on terms

32


Table of Contents

satisfactory to us when we require it, our ability to continue to support our business growth and respond to business challenges could be significantly impaired, and our business and prospects could be adversely affected.

Risks Related to Being a Public Company

If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired.

        Ensuring that we have adequate internal financial and accounting controls and procedures in place to produce accurate financial statements on a timely basis is a costly and time-consuming effort that needs to be re-evaluated frequently. The rapid growth of our operations and the planned initial public offering has created a need for additional resources within the accounting and finance functions due to the increasing need to produce timely financial information and to ensure the level of segregation of duties customary for a U.S. public company. We continue to reassess the sufficiency of finance personnel in response to these increasing demands and expectations.

        Our management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our management does not expect that our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within our company will have been detected.

We have identified material weaknesses in our internal control over financial reporting and may experience additional material weaknesses in the future. Our failure to remediate these material weaknesses and maintain effective internal control over financial reporting could result in material misstatements in our financial statements, the inability to timely report our financial condition or results of operations, investors losing confidence in our reported financial information and our stock price being adversely affected.

        Management and our independent registered public accounting firm have identified material weaknesses in our internal control over financial reporting that affected our financial statements for each of the years in the two year period ended December 31, 2019. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Internal Control Over Financial Reporting."

        The material weaknesses in our internal control over financial reporting during each of the years ended December 31, 2018 and 2019 related to the implementation of ASC 606, application of software capitalization guidance and recording of impairments, and our procedures for segregating user access to financially significant systems, which resulted in a lack of segregation of incompatible duties.

        We cannot assure you that additional material weaknesses in our internal control over financial reporting will not be identified in the future. The failure to maintain effective internal control over financial reporting could result in errors in our financial statements that could result in a restatement of financial statements, cause us to fail to meet our periodic reporting obligations and cause investors to lose confidence in our reported financial information, which could lead to a decline in our stock price.

We are an "emerging growth company" and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our Class A common stock less attractive to investors.

        We are an "emerging growth company" as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates. We have elected to use this extended transition period and we intend to utilize this related to the FASB issued ASU No. 2016-02, Leases. This standard amends several aspects of lease accounting, including requiring lesees to recognize operating leases with a term greater than one year on their balance sheet as a right-of-use asset, and a corresponding lease liability, measured at the present value of the future minimum lease payments. The standard is effective for public companies for fiscal years beginning after December 15, 2018, and after December 15, 2020 for all other companies, with early adoption permitted. We intend to adopt this standard effective January 1, 2021 using the modified retrospective transition method and therefore will not restate comparative periods. While we have not yet quantified the impact, resulting adjustments are expected to materially increase total assets and total liabilities relative to such amounts reported prior to adoption, but not have a material impact on the consolidated statements of comprehensive income (loss) or consolidated statements of cash flows.

        For as long as we continue to be an emerging growth company, we also intend to take advantage of certain other exemptions from various reporting requirements that are applicable to other public companies including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our Class A common stock less attractive because we will rely on these exemptions. If some investors find our Class A common stock less attractive as a result, there may be a less active trading market for our Class A common stock and our stock price may be more volatile.

        We will remain an emerging growth company until the earliest of (i) the last day of the year in which we have total annual gross revenue of $1.07 billion or more; (ii) the last day of the year following the fifth anniversary of the date of the closing of this offering; (iii) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the SEC.

The requirements of being a public company may strain our resources, divert management's attention and affect our ability to attract and retain qualified board members.

        As a public company, we will be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, (the "Exchange Act"), the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act"), the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of the Nasdaq Global Market on which our Class A common stock will be traded and other applicable securities rules and regulations. The SEC and other regulators have continued to adopt new rules and regulations and make additional changes to existing regulations that require our compliance. Stockholder activism, the current political environment and the current high level of government intervention and regulatory reform may lead to substantial new regulations and disclosure obligations, which may lead to additional compliance costs and impact, in ways we cannot currently anticipate, the manner in which we operate our business. We will need to institute a comprehensive compliance function and establish internal policies to ensure we have the ability to prepare financial statements that are fully compliant with all SEC reporting requirements on a timely basis and establish an investor

Table of Contents

relations function. Compliance with these rules and regulations may cause us to incur additional accounting, legal and other expenses that we did not incur as a private company. We also anticipate that we will incur costs associated with corporate governance requirements, including requirements under securities laws, as well as rules and regulations implemented by the SEC and the Nasdaq Global Market, particularly after we are no longer an "emerging growth company." We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly, while also diverting some of management's time and attention from revenue-generating activities. Furthermore, these rules and regulations could make it more difficult or more costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers. We are currently evaluating and monitoring developments with respect to these rules and regulations, and we cannot predict or estimate the amount of additional costs we may incur or the timing of such costs.

Our management team has limited experience managing a public company.

        Most members of our management team have limited experience managing a publicly traded company, interacting with public company investors and complying with the increasingly complex laws pertaining to public companies. Our management team may not successfully or efficiently manage our transition to being a public company that is subject to significant regulatory oversight and reporting obligations under the federal securities laws and the continuous scrutiny of securities analysts and investors. These new obligations and constituents will require significant attention from our senior management and could divert their attention away from the day-to-day management of our business, which could harm our business, results of operations, and financial condition.

Risks Related to This Offering and Ownership of Our Class A Common Stock

There is no existing market for our Class A common stock, and we do not know if one will develop to provide you with adequate liquidity to sell our Class A common stock at prices equal to or greater than the price you paid in this offering.

        Prior to this offering, there has been no public market for our Class A common stock. We cannot predict the extent to which investor interest in our company will lead to the development of an active trading market or how liquid that market may become. If an active trading market does not develop, you may have difficulty selling any of our shares that you purchase. The initial public offering price of our Class A common stock was determined by negotiation between the underwriters, us and the selling stockholders, and may not be indicative of prices that will prevail after the completion of this offering. The market price of our Class A common stock may decline below the initial public offering price, and you may not be able to resell your shares at, or above, the initial public offering price.

Substantial future sales of shares of our Class A common stock could cause the market price of our Class A common stock to decline.

        Sales of a substantial number of shares of our Class A common stock following the closing of this offering, particularly sales by our directors, executive officers and significant stockholders, or the perception that these sales might occur, could depress the market price of our Class A common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that such sales may have on the prevailing market price of our common stock.

        All of our executive officers, directors and the holders of substantially all of our capital stock are subject to lock-up agreements that restrict their ability to transfer shares of our capital stock for 180 days from the date of this prospectus. Subject to certain exceptions, the lock-up agreements limit

35


Table of Contents

the number of shares of capital stock that may be sold immediately following this offering. Goldman Sachs & Co. LLC and Morgan Stanley & Co. LLC may, in their sole discretion, permit our stockholders who are subject to these lock-up agreements to sell shares prior to the expiration of the lock-up agreements. Upon the closing of this offering, we will have 120,417,000 outstanding shares of our Class B common stock (all of which are convertible into Class A common stock on a one-for-one basis) and 22,576,819 outstanding shares of our Class A common stock, based on the number of shares outstanding as of June 30, 2020. This includes the shares included in this offering, which may be sold in the public market immediately without restriction or further registration under the Securities Act of 1933, as amended (the "Securities Act"), except for any shares held by our affiliates as defined in Rule 144 under the Securities Act.

The dual class structure of our common stock will have the effect of concentrating voting control with those stockholders who held our capital stock prior to the completion of this offering, including our existing stockholders, who will hold in the aggregate 98% of the voting power of our capital stock following the completion of this offering. This will limit or preclude your ability to influence corporate matters, including the election of directors, amendments to our organizational documents and any merger, consolidation, sale of all or substantially all of our assets, or other major corporate transaction requiring stockholder approval.

        Our Class B common stock has ten votes per share and our Class A common stock, which is the stock we are offering in this initial public offering, has one vote per share. The dual class structure of our common stock has the effect of concentrating voting control with those stockholders who held our capital stock prior to the completion of this offering, including our current principal stockholders and their affiliates, which will limit your ability to influence the outcome of matters submitted to our stockholders for approval, including the election of our directors and the approval of any change in control transaction. Future transfers by holders of Class B common stock will generally result in those shares converting to Class A common stock, which will have the effect, over time, of increasing the relative voting power of those holders of Class B common stock who retain their shares in the long term.

        Upon the completion of this offering, our current principal stockholders and their respective affiliates will hold, in aggregate 98% of the voting power of our outstanding capital stock. For more information, see "Principal Stockholders." As a result, these stockholders, acting together, will have control over most matters that require approval by our stockholders, including the election of directors and approval of significant corporate transactions. They may also have interests that differ from yours and may vote in a way with which you disagree and which may be adverse to your interests. Corporate action might be taken even if other stockholders, including those who purchase shares in this offering, oppose them. This concentration of ownership may have the effect of delaying, preventing or deterring a change of control or other liquidity event of our company, could deprive our stockholders of an opportunity to receive a premium for their shares of common stock as part of a sale or other liquidity event and might ultimately affect the market price of our common stock.

We cannot predict the impact our capital structure may have on our stock price.

        We cannot predict whether our dual class structure will result in a lower or more volatile market price of our Class A common stock, in adverse publicity or other adverse consequences. For example, certain index providers have announced restrictions on including companies with multiple-class share structures in certain of their indices. In July 2017, the FTSE Russell announced that it plans to require new constituents of its indices to have greater than 5% of the company's voting rights in the hands of public stockholders, and S&P Dow Jones announced that it will no longer admit companies with multiple-class share structures to certain of its indices. Affected indices include the Russell 2000 and the S&P 500, S&P MidCap 400 and S&P SmallCap 600, which together make up the S&P Composite 1500. Also in 2017, Morgan Stanley Capital International ("MSCI"), a leading stock index provider, opened public consultations on their treatment of no-vote and multi-class structures and temporarily

36


Table of Contents

barred new multi-class listings from certain of its indices; however, in October 2018, MSCI announced its decision to include equity securities "with unequal voting structures" in its indices and to launch a new index that specifically includes voting rights in its eligibility criteria. Under such announced policies, the dual class structure of our common stock would make us ineligible for inclusion in certain indices and, as a result, mutual funds, exchange-traded funds and other investment vehicles that attempt to passively track those indices would not invest in our Class A common stock. It is unclear what effect, if any, these policies will have on the valuations of publicly traded companies excluded from such indices, but it is possible that they may depress valuations, as compared to similar companies that are included. As a result, the market price of our Class A common stock could be adversely affected.

The price of our Class A common stock may fluctuate significantly, and you could lose all or part of your investment.

        The market price of our Class A common stock is likely to be volatile and could be subject to wide fluctuations in response to many risk factors listed in this section, and others beyond our control, including:

        Recently, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry fluctuations, as well as general economic, political, regulatory and market conditions, may negatively impact the market price of our Class A common stock. If the market price of our Class A common stock after this offering does not exceed the public offering price, you may lose some or all of your investment. In the past, companies that have experienced volatility in the market price of their securities have been subject to securities class action litigation. We may be the target of this type of litigation in the future, which could result in substantial costs and divert our management's attention.

We have entered into a tax sharing agreement with our existing stockholders and could become obligated to make payments to our existing stockholders for any additional federal, state or local income taxes assessed against them for tax periods prior to the completion of this offering.

        Prior to this offering, we have elected to be treated as an S Corporation for U.S. federal income tax purposes, as a result of which, our existing stockholders have been required to pay income taxes attributable to our earnings. We have historically paid distributions to our existing stockholders, which have assisted them in paying such income taxes. In connection with this offering, our S Corporation

status will terminate and we will thereafter be subject to federal and increased state income taxes. Our existing stockholders may be required to pay additional income taxes for periods prior to the termination of our S Corporation status as a result of an adjustment to our taxable income for periods beginning after our S corporation status terminates. Accordingly, we intend to enter into an agreement with our existing stockholders in connection with this offering pursuant to which we may be required to make payments in material amounts to our existing stockholders with respect to any incremental income taxes resulting from an adjustment to our taxable income for any period beginning after our S Corporation status terminates. Furthermore, this agreement requires us to indemnify our existing stockholders with respect to unpaid income tax liabilities attributable to our taxable income for any period after the termination of our S Corporation status. We will also indemnify our existing stockholders for any interest, penalties, losses, costs or expenses arising out of any claim under the agreement. However, our existing stockholders will indemnify us with respect to our unpaid tax liabilities (including interest and penalties) to the extent that such unpaid tax liabilities are attributable to a decrease in our existing stockholders' taxable income for any period and a corresponding increase in our taxable income for any period. See "Certain Relationships and Related Party Transactions—Tax Sharing Agreement."

Prior to this offering, we were treated as an S Corporation, and claims of taxing authorities related to our prior status as an S Corporation could harm us.

        In connection with this offering, our status as an S Corporation will terminate and we will be taxed as a C Corporation, which is subject to entity-level federal income taxes under the Code. If one or more tax years for which we filed a tax return as an S Corporation are audited by the IRS, and we are determined not to have qualified for, or not to have properly maintained, our S Corporation status, we may be obligated to pay entity-level income tax, plus interest and possible penalties. The amounts that we could be obligated to pay could include taxes with respect to all of our taxable income for periods when we believed we properly were treated as an S Corporation. Any such claims could result in additional costs to us and could have a material adverse effect on our financial results.

We do not intend to pay dividends on our Class A common stock for the foreseeable future and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our Class A common stock.

        We currently intend to retain all available funds and any future earnings for use in the operation of our business and do not anticipate paying any dividends on our Class A common stock in the foreseeable future. Any determination to pay dividends in the future will be at the discretion of our board of directors. Consequently, your only opportunity to achieve a return on your investment in our company will be if the market price of our Class A common stock appreciates and you sell your shares at a profit. There is no guarantee that the price of our Class A common stock that will prevail in the market will ever exceed the price that you paid.

If securities or industry analysts do not publish or cease publishing research or reports about us, our business or our market, or if they change their recommendations regarding our Class A common stock adversely, the trading price of our Class A common stock and trading volume could decline.

        The trading market for our Class A common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. We do not control these analysts. If any of the analysts who cover us downgrade our Class A common stock or our industry, or the stock of any of our competitors, or publish inaccurate or unfavorable research about our business, the price of our Class A common stock may decline. If analysts cease coverage of us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the price or trading volume of our Class A common stock to decline and our Class A common stock to be less liquid.

Purchasers in this offering will experience immediate and substantial dilution in the net tangible book value of their investment.

        The offering price of our Class A common stock is substantially higher than the net tangible book value per share of our Class A common stock, which after giving effect to this offering was $(0.19) per share of our Class A common stock as of June 30, 2020. As a result, you will incur immediate and substantial dilution in net tangible book value when you buy our Class A common stock in this offering. This means that you will pay a higher price per share than the amount of our total tangible assets, less our total liabilities, divided by the number of shares of all of our common stock outstanding. In addition, you may also experience additional dilution if rights to purchase our common stock that are outstanding or that we may issue in the future are exercised or converted or we issue additional shares of our common stock at prices lower than our net tangible book value at such time. See "Dilution."

Anti-takeover provisions contained in our charter documents and Delaware law could prevent a takeover that stockholders consider favorable and could also reduce the market price of our stock.

        Our amended and restated certificate of incorporation contains provisions that could delay or prevent a change in control of our company. These provisions could also make it more difficult for stockholders to elect directors and take other corporate actions. These provisions include:

        These and other provisions in our amended and restated certificate of incorporation and under Delaware law could discourage potential takeover attempts, reduce the price investors might be willing to pay in the future for shares of our Class A common stock and result in the market price of our Class A common stock being lower than it would be without these provisions. For more information, see the section of this prospectus captioned "Description of Capital Stock—Anti-Takeover Provisions."

Our amended and restated certificate of incorporation provides, subject to certain exceptions, that the Court of Chancery of the State of Delaware is the sole and exclusive forum for certain stockholder litigation matters, and that the federal district courts will be the exclusive forum for claims under the Securities Act of 1933, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or stockholders.

        Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for:

Table of Contents

        In addition, our amended and restated certificate of incorporation provides that the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended (the "Securities Act").

        By becoming a stockholder in our Company, you will be deemed to have notice of and have consented to the provisions of our amended and restated certificate of incorporation related to choice of forum. This exclusive forum provision may limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage lawsuits against us and our directors, officers and other employees. This provision will not apply to claims arising under the Exchange Act. The enforceability of similar exclusive forum provisions (including exclusive federal forum provisions for actions, suits or proceedings asserting a cause of action arising under the Securities Act) in other companies' organizational documents has been challenged in legal proceedings, and there is uncertainty as to whether courts would enforce the exclusive forum provisions in our certificate of incorporation. Additionally, our stockholders cannot waive compliance with the federal securities laws and the rules and regulations thereunder. If a court were to find the exclusive forum provision in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the dispute in other jurisdictions, which could seriously harm our business.

We are a "controlled company" within the meaning of the Nasdaq Rules and, as a result, expect to qualify for, and intend to rely on, exemptions from certain corporate governance requirements. You will not have the same protections afforded to stockholders of companies that are subject to such requirements.

        After this offering, our current principal stockholders will continue to beneficially own a majority of the combined voting power of all classes of our outstanding voting stock. As a result, we will continue to be a controlled company within the meaning of the applicable stock exchange corporate governance standards. Under the Nasdaq Rules, a company of which more than 50% of the voting power is held by another person or group of persons acting together is a controlled company and may elect not to comply with certain corporate governance requirements, including the requirements that:

        These requirements will not apply to us as long as we remain a controlled company. We have elected to take advantage of the exemption from the requirement that a majority of our board of directors consist of independent directors and that our nominating and corporate governance committee consist entirely of independent directors. Accordingly, you may not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of the Nasdaq Global Market.

USE OF PROCEEDS

        We estimate that the net proceeds to us from the sale of the shares of our Class A common stock in this offering will be approximately $369.4 million, after deducting underwriting discounts and commissions and estimated offering expenses payable by us. If the underwriters exercise their over-allotment option to purchase additional shares in this offering in full, we estimate that our net proceeds will be approximately $416.7 million, after deducting underwriting discounts and commissions and estimated offering expenses payable by us. We will not receive any of the proceeds from any sale of shares in this offering by the selling stockholders.

        We intend to use a portion of the net proceeds to repay all outstanding indebtedness under our existing New Credit Agreement and to pay related fees and expenses. As of March 31, 2020, our indebtedness includes $175.0 million outstanding under the term loan entered into under the New Credit Agreement. Proceeds from the term loan were used to repay amounts outstanding under the Company's previous credit agreement of $61.7 million, with the balance being used to fund a portion of a $123.0 million dividend to our stockholders on May 29, 2020, $122.8 million of which was paid to our directors Amanda Westphal Radcliffe, Stefanie Westphal Thompson and Jeffrey Westphal and, in each case, related trusts held for his or her benefit or the benefit of his or her immediate family. The term loan bears interest at a rate of 2.50% and will become due in March 2023. In addition, we intend to use approximately $22.9 million of the proceeds from this offering to pay for costs we expect to incur in connection with the payment of withholding taxes of approximately $13.8 million and the repurchase by us of approximately 476,530 shares of Class A common stock for approximately $9.1 million as a result of the amendment of outstanding SARs as part of this offering. See "Executive Compensation." The remainder of the net proceeds will be used for working capital and other general corporate purposes, including investments in our products, technology and sales force. Under the terms of the New Credit Agreement, this offering will constitute a triggering event, which will require the immediate repayment of the New Term Loan.

DIVIDEND POLICY

        Historically, we have been an S Corporation, and as such, we have paid distributions to our existing stockholders, which have assisted them in paying the U.S. federal and state income taxes on our taxable income that is "passed through" to them, and we have historically made additional distributions to them for returns on capital.

        We do not currently anticipate paying dividends on our Class A or Class B common stock. Any declaration and payment of future dividends to holders of our Class A and Class B common stock will be at the discretion of our board of directors and will depend on many factors, including our financial condition, earnings, capital requirements, level of indebtedness, statutory and contractual restrictions applying to the payment of dividends and other considerations that our board of directors deems relevant. In addition, the terms of the agreements governing our indebtedness may limit our ability to pay dividends.

DILUTION

        If you invest in our Class A common stock in this offering, your ownership interest will be immediately diluted to the extent of the difference between the initial public offering price per share of our Class A common stock and the pro forma as adjusted net tangible book value per share of our Class A common stock after this offering. Dilution results from the fact that the per share public offering price of the Class A common stock is substantially in excess of the book value per share of our Class A common stock after this offering. Our pro forma net tangible book value as of March 31, 2020 was $(315.8) million, or $(2.62) per share of our Class A common stock, after giving effect to (i) the termination of our status as an S Corporation in connection with and prior to the closing of this offering (which was effective on July 28, 2020), (ii) the reclassification of our existing voting and non-voting common stock on July 28, 2020, pursuant to which each share of our common stock outstanding immediately prior to the reclassification became one share of Class B common stock, except for 172,500 shares of our non-voting stock that were held by individuals other than members of our founder's family, which were reclassified as Class A common stock and (iii) the payment of a dividend in the amount of $123.0 million to our existing stockholders (which was completed on May 29, 2020). Net tangible book value per share is determined as stockholders' deficit reduced by goodwill (which was $20.2 million as of March 31, 2020), and not adjusted for deferred commissions, divided by the total number of shares of our common stock outstanding.

        After giving effect to (a) the sale of 21,150,000 shares of Class A common stock that we are offering, (b) the issuance of (i) 562,199 shares of Class A common stock in connection with the amendment and exercise of certain fully vested SARs and (ii) 692,120 shares of Class A common stock and restricted stock in connection with awards under the 2020 Plan and (c) the application of the proceeds from this offering as described in "Use of Proceeds," after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, as if each had occurred on March 31, 2020, our pro forma as adjusted net tangible book value as of March 31, 2020 would have been $51.7 million, or $0.36 per share of common stock. This amount represents an immediate increase in net tangible book value of $2.98 per share of common stock to our existing stockholders before this offering and an immediate and substantial dilution in net tangible book value of $18.64 per share of common stock to new investors purchasing shares of common stock in this offering. We determine dilution by subtracting the pro forma as adjusted net tangible book value per share of common stock after this offering from the amount of cash that a new investor paid for a share of common stock in this offering. The following table illustrates this dilution, assuming the underwriters do not exercise their option to purchase additional shares of common stock:

Assumed initial public offering price per share of Class A common stock

        $ 19.00  

Pro forma net tangible book value per share of common stock as of March 31, 2020

  $ (2.62 )      

Increase in pro forma net tangible book value per share of common stock attributable to new investors in this offering

    2.98        

Pro forma as adjusted net tangible book value per share of common stock immediately after this offering

          0.36  

Dilution in pro forma net tangible book value per share of common stock to new investors in this offering

        $ 18.64  

        If the underwriters' option to purchase additional shares of Class A common stock is exercised in full, the as pro forma adjusted net tangible book value per share of Class A common stock would be $0.68 per share, and the dilution in pro forma as adjusted net tangible book value per share of Class A common stock to new investors in this offering would be $18.32 per share.

        During the past five years, none of our officers, directors or affiliates acquired any shares of our common stock or have had the right to acquire any shares of our common stock, other than the equity awards being granted to certain of our directors, officers and employees in connection with this offering and the amendment of our outstanding SARs, in each case as described under "Executive and Director Compensation."

SELECTED CONSOLIDATED FINANCIAL INFORMATION

        The following table sets forth our selected historical consolidated financial information for the periods and dates indicated. The consolidated balance sheet data as of December 31, 2019 and 2018 and the consolidated statements of comprehensive income (loss) for the years ended December 31, 2019 and 2018 have been derived from our audited consolidated financial statements included elsewhere in this prospectus. The consolidated balance sheet data as of March 31, 2020 and the consolidated statements of comprehensive income (loss) for the three months ended March 31, 2020 and 2019 have been derived from our unaudited consolidated financial statements appearing elsewhere in this prospectus. The unaudited interim consolidated financial statements have been prepared on the same basis as the audited annual consolidated financial statements and reflect, in the opinion of management, all adjustments of a normal, recurring nature that are necessary for a fair statement of the unaudited interim consolidated financial statements.

        The financial information set forth below is not necessarily indicative of future results of operations. In particular, we have historically been taxed as an S Corporation for U.S. federal income tax purposes and for income tax purposes in most states. As a result, net income or loss has been allocated to our stockholders and included on their individual income tax returns. Effective July 27, 2020 we converted to a C Corporation, which will result in our net income being taxed at the corporate level. As such, our provision for taxes will change. Upon the conversion to a C Corporation, we estimate that our effective tax rate will be approximately 25%, inclusive of all applicable U.S. federal, state, local and foreign income taxes. In addition, based on the deferred tax asset balances at March 31, 2020, we would anticipate recording a tax benefit of approximately $8.5 million as if the conversion had occurred on such date.

        Share amounts for all periods presented, including the number of shares that common stock equivalents are convertible into, were retrospectively restated to reflect the three-for-one forward stock split which was effective on July 28, 2020.

        This data should be read in conjunction with, and is qualified in its entirety by reference to, the "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Capitalization" sections of this prospectus and our audited consolidated financial statements and notes thereto for the periods and dates indicated included elsewhere in this prospectus. Revenue is reflected in accordance with ASC 606, which we adopted on January 1, 2018.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

        You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the consolidated financial statements and the notes thereto included elsewhere in this prospectus. In addition to historical financial information, the following discussion contains forward-looking statements that reflect our plans, estimates, beliefs and expectations that involve risks and uncertainties. Our actual results and the timing of events could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this prospectus, particularly in the sections of this prospectus titled "Risk Factors" and "Special Note Regarding Forward-Looking Statements."

Overview

        Vertex delivers comprehensive tax solutions that enable global businesses to transact, comply and grow with confidence. Companies with complex tax operations rely on Vertex to automate their end-to-end indirect tax processes. Indirect tax is the largest corporate tax category, encompassing sales tax, seller's use tax, consumer use tax and VAT, among others. Indirect tax accounts for more than $3.5 trillion of annual tax revenue, which is 2.5 times the amount of corporate income taxes, according to the 2019 OECD Tax Database. Our software, content and services address the increasing complexities of global commerce and compliance by reducing friction, enhancing transparency and enabling greater confidence in meeting indirect tax obligations. As a result, our software is ubiquitous within our customers' business systems, touching nearly every line item of every transaction that an enterprise can conduct.

        We have pioneered tax technology for over 40 years. We first began electronic delivery of tax rules in the early 1980s and we first sold transaction tax processing software in 1982. Today, our software enables tax determination, compliance and reporting, tax data management and document management with powerful pre-built integrations to core business applications used by most companies, particularly those applications that have a significant impact on global commerce. Our software is fueled by over 300 million data-driven effective tax rules and supports indirect tax compliance in more than 19,000 jurisdictions worldwide. In order to maintain the quality of our content, our team includes many global tax and regulatory experts from industry and the public sector, who deliver monthly updates to our tax content, which are then incorporated directly into our software. Our solutions can be deployed on-premise, in the cloud, or both, with implementation services available to enable optimal customer outcomes and satisfy their unique business requirements.

        We have accumulated industry-specific tax knowledge for over four decades and our customers leverage our in-depth content through their use of our software. This allows our customers to comply with the dynamic regulatory landscape in real time and mitigates our customers' risk exposure. As our customers expand their global footprint and business models, we are actively supporting their expansion by continuously strengthening our content offering and allowing for additional jurisdiction-specific tax compliance.

        We derive the majority of our revenue from software subscriptions. These subscriptions include use of our software and ongoing monthly content updates. Our software is offered on a subscription basis to our customers, regardless of their deployment preferences. On-premise subscriptions are typically sold through one-year contracts and cloud-based subscriptions are typically sold through one- to three-year contracts. We bill almost all of our customers annually in advance of the subscription period.

        We have over 4,000 customers, including the majority of the Fortune 500, as well as a majority of the top 10 companies by revenue in multiple industries such as retail, technology and manufacturing, in addition to leading marketplaces. At March 31, 2020, we had over 4,000 customers and our ARR per customer was over $70,000, while at March 31, 2019, we had over 4,000 customers and our ARR per customer was over $59,000. As our customers expand geographically and pursue omnichannel business models, their tax determination and compliance requirements increase and become more complex, providing sustainable organic growth opportunities for our business. Our pricing model is aligned with our customers' objectives by adjusting with their growth over time. We principally price our solutions based on a customer's revenue base, in addition to a number of other factors.

        We employ a hybrid deployment model to align to our customers' technology preferences for their core financial management software across on-premise, cloud deployments or any combination of these models. Over time, we expect both existing and newly acquired customers to continue to shift towards cloud deployment models. Cloud-based subscription sales to new customers have grown at a significantly faster rate than on-premise software subscription sales, which is a trend that we expect to continue over time. We generated 12.9% and 19.1% of software subscription revenue from cloud-based subscriptions in 2018 and 2019, respectively, and 16.6% and 24.1% for the three months ended March 31, 2019 and 2020, respectively. While our on-premise software subscription revenue comprises 80.9% of our 2019 software subscription revenue, we anticipate that it will decrease as a percentage of total software subscription revenue as cloud-based subscriptions accelerate.

        We sell our solutions primarily through our direct sales force, which focuses on selling to qualified leads provided by our marketing efforts, and through our network of referral partners. We also utilize indirect sales to a lesser extent to efficiently grow and scale our enterprise and mid-market revenues.

        Our partner ecosystem is a differentiating, competitive strength in both our software development and our sales and marketing activities. We integrate with key technology partners that span ERP, CRM, procurement, billing, POS and eCommerce. These partners include Adobe/Magento, Coupa, Microsoft Dynamics, NetSuite, Oracle, Salesforce, SAP, SAP Ariba, Workday and Zuora. We also collaborate with numerous accounting firms who have built implementation practices around our software to serve their customer base.

        We believe that global commerce and compliance environment provides durable and accelerating growth opportunities for our business. We generated revenue of $272.4 million and $321.5 million in 2018 and 2019, respectively, and $74.6 million and $89.2 million for the three months ended March 31,

53


Table of Contents

2019 and 2020, respectively. We had a net loss of $6.1 million and net income of $31.1 million in 2018 and 2019, respectively, and net income of $7.3 million and a net loss of $29.1 million for the three months ended March 31, 2019 and 2020, respectively. Adjusted EBITDA was $61.5 million and $67.9 million in 2018 and 2019, respectively, and $15.6 million and $15.3 million for the three months ended March 31, 2019 and 2020, respectively. Additionally, we generated net cash provided by operating activities of $80.4 million and $92.5 million in 2018 and 2019, respectively, and $9.9 million and $(6.4) million in the three months ended March 31, 2019 and 2020, respectively. Our free cash flow was $47.1 million and $54.9 million in 2018 and 2019, respectively, and $1.8 million and $(15.8) million in the three months ended March 31, 2019 and 2020, respectively. Adjusted EBITDA and free cash flow are non-GAAP financial measures. For more information about how we use these non-GAAP financial measures in our business, the limitations of these measures and reconciliations to the most directly comparable GAAP measures, see "Prospectus Summary—Summary Consolidated Financial and Operating Information." In connection with the offering, we will convert from an S Corporation to a C Corporation, which will result in net income of the Company being taxed at the corporate level. For additional information on the effect of such conversion, see "Prospectus Summary—Summary Consolidated Financial and Operating Information."

Key Factors Affecting Performance

        The growth of our business and our future success depends on many factors, including our ability to retain and expand our revenue from existing customers, acquire new customers, deepen our partner ecosystem, continually innovate our software and invest in growth and scale our business. While these areas represent significant opportunities for us, we also face significant risks and challenges that we must successfully address in order to sustain the growth of our business and improve our operating results. We anticipate that we will continue to expand our operations and headcount. The expected addition of new personnel and the investments that we anticipate will be necessary to manage our anticipated growth may make it more difficult for us to achieve or maintain profitability. Many of these investments will occur in advance of experiencing any direct benefit and will make it difficult to determine if we are allocating our resources efficiently.

        Retention and expansion of revenue from existing customers.    Given the breadth of our customer base and their own internal growth, the majority of our revenue and revenue growth comes from existing customers. This revenue growth is comprised of the acquisition of new licenses for additional products, increases in subscription fees due to expanded usage of currently licensed software and price increases. We plan to continue to invest in new innovations and offerings and in our sales and marketing teams in order to support the ongoing strong retention and expansion of revenue with our existing customers. We track net revenue retention rate ("NRR") in order to understand our ability to retain and grow revenue from our customers. Our NRR was 109% as of December 31, 2019 and March 31, 2020.

        Acquire new customers.    Our solutions address the complexity of aligning commerce and compliance and we believe the market for our solutions is large and underpenetrated, both in the United States and globally. As enterprise and mid-market companies continue to expand their business operations—both through their product and service offerings and their global footprint—we expect demand for our tax solutions to increase due to the fact that legacy solutions such as spreadsheets, manual processes, native ERP functionality or home-built solutions are error prone, inefficient and cannot scale. We plan to continue to invest in our sales and marketing teams and our solution development in order to address this increased demand from new customers. This increased investment will result in increases in expenses in advance of revenues attributable to these investments.

        Broaden and deepen our partner ecosystem.    We have an extensive network of partners that spans ERP, CRM, procurement, billing, POS and eCommerce platforms. Our partners enhance the coverage and adoption of our solutions and promote our thought leadership. We leverage our partnerships to

54


Table of Contents

maximize the benefits of our solutions for our customers and to identify new customer opportunities. By forming additional strategic alliances with participants in the global digital transformation, such as payments and eCommerce platforms, we can continue to expand our exposure to all transactions, both B2C and B2B. Future partnerships with large-scale digital payments companies will allow us to develop additional customer-centric solutions and further expand our customer base.

        Continued innovation of our software.    With the pace of change in commerce and compliance, we believe it is important to continue innovating and extending the functionality and breadth of our software. We plan on investing to further enhance our content and the speed and usability of our software. We believe continuing to enhance our existing software will increase our ability to generate revenue by broadening the appeal of our software to new customers as well as increasing our engagement with existing customers.

        Investing in growth and scaling our business.    We believe that our market opportunity is large, and we will continue to invest significantly in scaling across organizational functions in order to support the anticipated growth in our operations both domestically and internationally. Any investments we make in our research and development and our sales and marketing organization will occur in advance of experiencing the benefits from such investments, so it may be difficult for us to determine if we are efficiently allocating resources in those areas.

        Customer migration to cloud solutions.    Over time, we expect a continued shift to our cloud solutions from existing and newly acquired customers. Over the past two years, cloud sales to new customers have grown at a significantly faster rate than sales of on-premise solutions, which is a trend that we expect to continue over time. We generated 12.9% and 19.1% of software subscription revenue from cloud-based subscriptions in 2018 and 2019, respectively. For the three months ended March 31, 2020, we generated 24.1% of software subscription revenue from cloud-based subscriptions, an increase from 16.6% for the three months ended March 31, 2019. We recognize revenue from the sale of cloud-based subscriptions ratably over the life of the contract, whereas for on-premise subscriptions, the first year pricing includes a premium that is not included in future renewal pricing. The premium is recognized ratably over the estimated period of benefit to the customer, which is generally three years. Therefore, as more of our sales shift to cloud-based subscriptions, our revenue growth rate may increase. We provide hosting for our cloud-based subscriptions. To the extent that revenue from our cloud offerings increase as a percentage of total revenue, our gross margin may decrease due to the associated hosting costs of those offerings.

Recent Developments—Impact of COVID-19

        In March 2020, the World Health Organization declared the outbreak of COVID-19 to be a pandemic. The COVID-19 pandemic is having widespread, rapidly evolving and unpredictable impacts on global society, economies, financial markets and business practices. Federal and state governments have implemented measures in an effort to contain the virus, including social distancing, travel restrictions, border closures, limitations on public gatherings, work from home, supply chain logistical changes and closure of non-essential businesses. To protect the health and well-being of our employees and customers, we have made substantial modifications to employee travel policies, closed our offices as employees are advised to work from home and cancelled or shifted our conferences and other marketing events to virtual-only. The COVID-19 pandemic has impacted and may continue to impact our business operations, including our employees, customers and partners, and there is substantial uncertainty in the nature and degree of its continued effects over time.

        During the first quarter of 2020, the COVID-19 pandemic had minimal impact on our revenue or results of operations, as we continue to derive the significant majority of our revenue from our existing software subscriptions. As we principally price our solutions based on our customers' revenues within certain revenue bands, elongated declines in our existing customers' revenues may impact our ability to

55


Table of Contents

grow our existing customer revenues. We did not experience an abnormal number of non-renewals in the first or second quarter of 2020, nor any declines in revenue associated with declines in our customers' revenues, and we currently expect our existing customer base to remain largely stable, as it did through the recession in 2008 and 2009. However, significant decreases in non-renewals or concessions to renewal customers would have a material impact on our revenues and cash flows. We did see a decline in new software subscription billings at the end of the first quarter of 2020. It is important to note that our sales metrics are assessed quarterly, and given the size and complexity of our sales process we often see variances from month to month due to legal or procurement processes. In the case of the first quarter of 2020 we achieved our new software billings targets as several deals were completed earlier in the quarter. The Company also experienced a negative variance in new software billings in the early part of the second quarter of 2020, but these billings picked up as the quarter progressed. For the second quarter of 2020, new software billings were in excess of our original second quarter of 2020 expectations. We have seen some delay due to prospects shifting to working remotely, and some due to economic uncertainty. We expect that the uncertainty caused by the COVID-19 pandemic could continue to impact our billings to new customers for the remainder of 2020, and it may also negatively impact our efforts to expand revenues from our existing customers as they continue to evaluate certain long-term projects and budget constraints. However, we do not anticipate that overall demand for our software and solutions, our ability to deliver such software and solutions, or that our growth strategies will be materially impacted by the COVID-19 pandemic, as companies continue to rely on the Company for their indirect tax solutions. There is potential for an increase in demand for our products over the long-term considering the amount of state debt being accumulated during the pandemic, which may result in increases in taxes and revenue department audits which our products are positioned to address customer needs.

        In addition to the impacts on our sales, our cash collections from existing customers were lower than expected at the end of the first quarter of 2020. During the second quarter of 2020, our collections exceeded our expectation as some of the procedural disruptions that customers experienced as they shifted to remote work in March had stabilized. We believe that we may see delays in collections over the coming months. However, we do not believe that these delays will materially impact our business; we continue to expect that we will be able to collect amounts due under subscription contracts from customer experiencing issues as a result of COVID-19, and we have not recorded an additional allowance for doubtful accounts in connection with any delays. Given that customers cannot forgo our monthly content updates, which are necessary to remain compliant with the most current regulations, we believe customers will continue to pay our renewal invoices in a timely, even if slightly elongated manner. We believe that we currently have ample liquidity and capital resources to continue to meet our operating needs, and our ability to continue to service our debt or other financial obligations is not currently impaired. For a further description of our liquidity, including the New Credit Agreement entered into on March 31, 2020, see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources."

        The extent to which the COVID-19 pandemic impacts our business going forward will depend on numerous evolving factors we cannot reliably predict, including the duration and scope of the pandemic; governmental, business, and individuals' actions in response to the pandemic; and the impact on economic activity, including the possibility of recession or financial market instability. These factors may adversely impact consumer, business and government spending on technology as well as customers' ability to pay for our products and services on an ongoing basis. This uncertainty also affects management's accounting estimates and assumptions, which could result in greater variability in a variety of areas that depend on these estimates and assumptions, including estimated allowance for subscription cancellations, product life cycles and estimated lives of long lived assets.

Key Business Metrics

        We regularly review several metrics identified below to evaluate growth trends, measure our performance, formulate financial projections and make strategic decisions.

        Annual Recurring Revenue.    We derive the vast majority of our revenue from recurring software subscriptions. We believe ARR provides us with visibility to our projected software subscription revenue in order to evaluate the health of our business. Because we recognize subscription revenue ratably, we believe investors can use ARR to measure our expansion of existing customer revenues, new customer activity, and as an indicator of future software subscription revenues. ARR is based on monthly recurring revenue ("MRR") from software subscriptions for the most recent month at period end, multiplied by twelve. MRR is calculated by dividing the software subscription price, inclusive of discounts, by the number of subscription covered months. MRR only includes customers with MRR at the end of the last month of the measurement period.

        ARR increased by $45.0 million or 19.2% from 2018 to 2019. The increase was primarily driven by $21.6 million of growth in revenues from existing customers through their expanded use of our solutions as well as price increases and $23.4 million of on-premise and cloud-based subscription sales of our tax solutions to new customers.

        ARR increased by $41.9 million or 17.3% during the three months ended March 31, 2020, as compared to the same period in 2019. The increase was primarily driven by $20.6 million of growth in revenues from existing customers through their expanded use of our solutions as well as price increases and $21.3 million of on-premise and cloud-based subscription sales of our tax solutions to new customers.

        Net Revenue Retention Rate.    We believe that our NRR provides insight into our ability to retain and grow revenue from our customers, as well as their potential long-term value to us. We also believe it demonstrates to investors our ability to expand existing customer revenues, which is one of our key growth strategies. Our NRR refers to the ARR expansion during the 12 months of a reporting period for all customers who were part of our customer base at the beginning of the reporting period. Our NRR calculation takes into account any revenue lost from departing customers or customers who have downgraded as well as any revenue expansion from upgrades, cross-sells or upsells of our software.

        The 500 basis point increase in NRR from 2018 to 2019 was primarily driven by growth of $21.6 million in recurring subscription revenues from existing customers through their expanded use of our solutions.

        The 300 basis point increase in NRR during the three months ended March 31, 2020, as compared to the same period in 2019, was primarily driven by growth of $20.6 million in recurring subscription revenues from existing customers through their expanded use of our solutions as well as price increases.

        Adjusted EBITDA and Adjusted EBITDA Margin.    We believe that Adjusted EBITDA is a measure widely used by securities analysts and investors to evaluate the financial performance of our company

57


Table of Contents

and other companies. We believe that Adjusted EBITDA and Adjusted EBITDA margin are useful as supplemental measures to evaluate our overall operating performance as they measure business performance focusing on cash related charges and because they are important metrics to lenders under our New Credit Agreement. We define Adjusted EBITDA as net income or loss before interest, taxes, depreciation, and amortization, as adjusted to exclude charges for asset impairments, gains or losses on assets and liabilities denominated in a foreign currency, share-based compensation expense, severance charges and transaction costs. Adjusted EBITDA margin represents Adjusted EBITDA divided by total revenues for the same period. For purposes of comparison, our net income (loss) in 2019 was $31.1 million and $(6.1) million in 2018, while our net income (loss) margin was 9.7% and (2.2)% over the same periods, respectively. Additionally, our net income (loss) was $(29.1) million and $7.3 million for the three months ended March 31, 2020 and 2019, respectively, while our net income margin was (32.7)% and 9.9% over the same periods, respectively.

        The increase in Adjusted EBITDA of $6.4 million in 2019 is primarily driven by an increase in gross profit, offset by an increase in operating expenses including additional sales and marketing and research and development investments. Adjusted EBITDA margin decreased in 2019, primarily because operating expenses increased at a higher rate than our increase in revenue. This growth in operating expenses is driven primarily by our ongoing investment in our research and development, sales and marketing organization and technology infrastructure to support our future growth.

        The decrease in Adjusted EBITDA for the three months ended March 31, 2020 of $0.3 million is primarily driven by an increase in operating expenses, including additional research and development and internal infrastructure investments, partially offset by an increase in gross profit. Adjusted EBITDA margin decreased for the three months ended March 31, 2020, primarily because operating expenses increased at a higher rate than our increase in revenue. This growth in operating expenses is driven primarily by our ongoing investment in our research and development, sales and marketing organization and technology infrastructure to support our future growth.

        Free Cash Flow and Free Cash Flow Margin.    Our management uses free cash flow as a critical measure in the evaluation of liquidity in conjunction with related GAAP amounts. We also use the measure when considering available cash, including for decision making purposes related to dividends and discretionary investments. We consider free cash flow to be an important measure for investors because it measures the amount of cash we generate from our operations after our capital expenditures and capitalization of software development costs. In addition, we base certain of our forward-looking estimates and budgets on free cash flow and free cash flow margin. We define free cash flow as the total of net cash provided by operating activities less purchases of property and equipment and capitalized software. We define free cash flow margin as free cash flow divided by total revenues for the same period. For purposes of comparison, our net cash provided by operating activities was $92.5 million and $80.4 million for the years ended December 31, 2019 and 2018, respectively, while our operating cash flow margin was 29% and 30% over the same periods, respectively. Our net cash used in operating activities was $(6.4) million and our net cash provided by operating activities was $9.9 million for the three months ended March 31, 2020 and 2019, respectively, while our operating cash flow margin was (7)% and 13% over the same periods, respectively. Net cash used in investing activities was $37.6 million and $33.3 million for the years ended December 31, 2019 and 2018, respectively, and $21.7 and $8.1 for the three months ended March 31, 2020 and 2019, respectively. Net cash used in financing activities was $30.6 million and $30.7 million for the years ended

        Free cash flow increased by $7.8 million in 2019 over 2018, driven primarily by an increase in cash from operating activities of $12.0 million, due to a $4.5 million increase in net income after excluding the impact of the asset impairment in 2018 and an increase in cash provided by changes in operating assets and liabilities. This amount is offset by an increase of $5.0 million in investments in capitalized software costs to support the growth of our customers. Free cash flow margin remained consistent with the prior year at 17%.

        Free cash flow decreased by $17.5 million for the three months ended March 31, 2020, driven primarily by a decrease in cash from operating activities of $16.3 million due to a reduction in cash provided by changes in operating assets and liabilities of $16.0 million. This reduction was primarily due to decreases in accrued and deferred compensation of $4.8 million, a reduction in deferred revenue of $7.6 million and a reduction in accounts receivable of $2.3 million. Accrued and deferred compensation decreased by $4.8 million due to payments for variable compensation for the first quarter of 2020 increasing over the prior year comparable quarter by $2.7 million due to increases in headcount, and due to payments of $2.8 million for stock appreciation right redemptions in the first quarter of 2020 as compared to the same quarter of 2019. Deferred revenue decreased $7.6 million due to a $4.8 million decrease in non-recurring extended product support fees billed in the first quarter of 2019 related to older versions of software subscription solutions retired during 2019. The balance of the deferred revenue reduction of $2.8 million, and the reduction in accounts receivable of $2.3 million are due primarily to modifications to billing frequencies requested by customers, primarily to align all the annual subscription billings for their subscription licenses to the same period. This results in a short-term reduction in deferred revenue, but no impact to revenue.

Components of Our Results of Operations

Revenue

        We generate revenue from software subscriptions and services.

        Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration expected to be received in exchange for those products or services. We enter into contracts that include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. Revenue is recognized net of allowance for subscription and non-renewal cancellations and any taxes collected from customers that are subsequently remitted to governmental authorities.

Software Subscriptions

        Licenses for on-premise software subscriptions, which are generally one year, provide the customer with a right to use the software as it exists when made available to the customer. Customers purchase a subscription to these licenses, which includes the related software and tax content updates and product support. The updates and support, which are part of the subscription agreement, are essential to the continued utility of the software; therefore, we have determined the software and the related updates and support to be a single performance obligation. Accordingly, when on-premise software is licensed,

59


Table of Contents

the revenue associated with this combined performance obligation is recognized ratably over the license term as these subscriptions are provided for the duration of the license term. Revenue recognition begins on the later of the beginning of the subscription period or the date the software is made available to the customer to download. Our on-premise software subscription prices in the initial subscription year are higher than standard renewal prices. The excess initial year price over the renewal price is a material right that provides customers with the right to this reduced renewal price. We recognize revenue associated with this material right over the estimated period of benefit to the customer, which is generally three years.

        Our cloud-based subscriptions allow customers to use Company-hosted software over the contract period without taking possession of the software. The contracts are generally for one to three years and are generally billed annually in advance of the subscription period. Our cloud-based offerings also include related updates and support. All services within the cloud-based contracts consistently provide a benefit to the customer during the subscription period, thus the associated revenue is recognized ratably over the subscription period. Revenue recognition begins on the later of the beginning of the subscription period or the date the customer is provided access to the cloud-based solutions.

        Revenue is impacted by the timing of sales and our customers' growth or contractions resulting in their need to expand or contract their subscription usage, the purchase of new solutions or the non-renewal of existing solutions. In addition, revenue will fluctuate with the cessation of extended product support fees charged for older versions of our software subscription solutions when they are retired and these fees are no longer charged. Contracts for on-premise licenses permit cancellations at the end of the license term, which is generally one year. Legacy cloud-based subscription contracts for multi-year periods previously provided customers the right to terminate their contract for services prior to the end of the subscription period at a significant penalty. This penalty requires the payment of a percentage of the remaining months of the then current contract term. Current cloud-based contracts do not contain such termination rights. Terminations of cloud-based subscriptions prior to the end of the subscription term have occurred infrequently and the impact has been immaterial. The allowance for subscription and non-renewal cancellations reflects an estimate of the amount of such cancellations and non-renewals based upon our historical experience.

Services Revenue

        We generate services revenue primarily in support of our customers' needs associated with our software and to enable them to realize the full benefit of our solutions. These software subscription-related services include configuration, data migration and implementation, and premium support and training. In addition, we generate services revenue through our managed services offering which allows customers to outsource all or a portion of their indirect tax operations to us. These services include indirect tax return preparation, filing and tax payment and notice management. We generally bill for services on a per-transaction or time and materials basis, and we recognize revenue from deliverable-based professional services as services are performed.

        Fluctuations in services revenue are directly correlated to fluctuations in our subscription revenues with respect to implementation and training services as we have historically experienced an attachment rate to subscription sales for these services in excess of 60%. Our managed services offering has recently experienced increased revenue associated with returns processing volume increases attributable to regulatory changes, as customers expanded their tax filings into more jurisdictions.

Cost of Revenue

Software Subscriptions

        Cost of software subscriptions revenue consists of costs related to providing and supporting our software subscriptions and includes personnel and related expenses, including salaries, benefits, bonuses

and stock-based compensation. In addition, cost of revenue includes direct costs associated with information technology, such as data center and software hosting costs, and tax content maintenance. Cost of revenue also includes amortization associated with direct labor and related expenses for capitalized internal-use software and developed software for new products and enhancements to existing products and cloud-based subscription solutions. We plan to continue to significantly expand our infrastructure and personnel to support our future growth and increases in transaction volumes of our cloud-based solutions, including through acquisitions. We expect growth in our business will result in an increase in cost of revenue in absolute dollars.

Services

        Cost of services revenue consists of direct costs of software subscription-related services and our managed services offering. These costs include personnel and related expenses, including salaries, benefits, bonuses, stock-based compensation and the cost of third-party contractors and other direct expenses. We plan to continue to expand our infrastructure and personnel as necessary to support our future growth and related increases in our service revenue. We expect growth in our business will result in an increase in the cost of services revenue in absolute dollars, but may decrease as a percentage of revenues as we scale our operations.

Research and Development

        Research and development expenses consist primarily of personnel and related expenses for our research and development activities, including salaries, benefits, bonuses and stock-based compensation, and the cost of third-party developers and other contractors. Research and development costs, other than software development expenses qualifying for capitalization, are expensed as incurred. For the years ended December 31, 2019 and 2018, $17.2 million and $12.3 million of software development costs were capitalized, respectively. For the three months ended March 31, 2020 and 2019, $3.7 million and $3.9 million of software development costs were capitalized, respectively. Capitalized software development costs consist primarily of employee-related and third-party labor costs.

        We devote substantial resources to developing new products and enhancing existing products, conducting quality assurance testing and improving our core technology. We believe continued investments in research and development are critical to attain our strategic objectives and expect research and development costs to increase in absolute dollars. These investments include enhancing our solution offerings to address changing customer needs to support their growth, as well as implementing changes required to keep pace with our partners' technology to ensure the continued ability of our solutions to work together and deliver value to our customers. The market for our solutions is characterized by rapid technological change, frequent new product and service introductions and enhancements, changing customer demands and evolving industry standards. As a result, although we are making significant research and development expenditures, which may be incurred and certain of which may be capitalized, there is no guarantee these solutions will be accepted by the market. This could result in increased costs or an impairment of capitalized development costs with no resulting future revenue benefit.

Selling and Marketing Expenses

        Selling expenses consist primarily of personnel and related expenses in support of sales and marketing efforts. These costs include salaries, benefits, bonuses and stock-based compensation. In addition, selling expense includes costs related to advertising and promotion efforts, branding costs, partner-based commissions and costs associated with our annual customer conferences. We intend to continue to invest in our sales and marketing capabilities in the future to continue to increase our brand awareness and expect these costs to increase on an absolute dollar basis as we grow our business and continue to expand our market and partner ecosystem penetration. Sales and marketing expense in

Table of Contents

absolute dollars and as a percentage of total revenue may fluctuate from period-to-period based on total revenue levels and the timing of our investments in our sales and marketing functions as these investments may vary in scope and scale over future periods.

General and Administrative

        General and administrative expenses consist primarily of personnel and related expenses for administrative, finance, information technology, legal, risk management, facilities and human resources staffing, including salaries, benefits, bonuses, stock-based compensation, professional fees, insurance premiums, facility costs and other internal support costs.

        We expect our general and administrative expenses to increase in absolute dollars as we continue to expand our operations, hire additional personnel, integrate future acquisitions and incur additional costs associated with becoming a publicly listed company. As a public company, we expect to incur increased expenses related to accounting, tax and auditing activities, legal, insurance, SEC compliance and internal control compliance.

Depreciation and Amortization

        Depreciation and amortization expense consists of the allocation of purchased and developed asset costs over the future periods benefitted by the use of these assets. These assets include leasehold improvements for our facilities, computers and equipment needed to support our customers and our internal infrastructure and capitalized internal-use software associated with our internal infrastructure and tools. Depreciation and amortization will fluctuate in correlation with our ongoing investment in internal infrastructure costs to support our growth.

Interest Income

        Interest income reflects earnings on investments of our cash on hand and on funds held for customers related to our managed outsourcing services. Interest income will vary as a result of fluctuations in the future level of funds available for investment and the rate of return available in the market on such funds.

Interest Expense

        Interest expense consists primarily of interest payments and other financing costs on our debt facility. Interest expense will vary as a result of fluctuations in the level of debt outstanding as well as interest rates on such debt.

Provision for Taxes

        We have been taxed as an S Corporation for U.S. federal income tax purposes and for income tax purposes in most states. As a result, net income or loss has been allocated to our stockholders and included on their individual income tax returns. In certain states, we have been taxed at the corporate level. Accordingly, the income tax provision or benefit is based on taxable income allocated to these states. In certain foreign jurisdictions, our subsidiaries were taxed at the corporate level. Similar to states, the income tax provision or benefit is based on taxable income sourced to these foreign jurisdictions.

        Effective July 27, 2020, we converted to a C Corporation, which will result in net income of the Company being taxed at the corporate level. As such, our provision for taxes will increase. Assuming the conversion to a C Corporation, we expect a pro forma entity level estimated effective tax rate of approximately 25%, inclusive of all applicable U.S. federal, state, local and foreign income taxes. In

addition, based on the deferred tax asset balances at March 31, 2020, we would anticipate recording a tax benefit of approximately $8.5 million if the conversion has occurred on such date.

Results of Operations

        You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the audited consolidated financial statements and the notes thereto included elsewhere in this prospectus. The period-to-period comparison of financial results is not necessarily indicative of financial results to be achieved in future periods. In particular, in connection with this offering, we will convert to a C Corporation, which will result in taxation at the corporate level.

        The following table sets forth our consolidated statements of comprehensive income (loss) for the periods indicated. Revenue is reflected in accordance with ASC 606, which we adopted on January 1, 2018.

Total revenue

  $ 89,245   $ 74,614   $ 14,631     19.6 %

        Revenue increased $14.6 million, or 19.6%, to $89.2 million for the three months ended March 31, 2020 compared to $74.6 million for the three months ended March 31, 2019. The increase in software subscriptions revenue of $11.4 million, or 17.7%, was primarily driven by $10.5 million in revenue growth derived from our existing customers and $0.9 million of revenue from new customers.

        The $3.3 million increase in services revenue is primarily driven by an increase of $2.5 million in software subscription-related services associated with the growth in subscription revenues, which includes new customers implementing our solutions and upgrading existing customers to newer versions of our solutions. In addition, our managed services offering experienced a $0.8 million increase in recurring services revenue over the prior year due to returns processing volume increases related to regulatory changes as customers expanded their tax filings into more jurisdictions.

Of this increase, 53.7% is due to an increase in stock-based compensation of $3.4 million for the three months ended March 31, 2020 over the same period in 2019. The balance of the increase of $2.9 million is due primarily to increased costs of personnel supporting year-over-year growth of sales and customers and ongoing infrastructure investments to support expansion of customer transaction volumes for our cloud-based subscription customers. As a percentage of total revenue, the cost of software subscriptions revenue increased to 27.7% for the three months ended March 31, 2020 compared to 24.7% in March 31, 2019. Adjusting for the increase in stock-based compensation in 2020, cost of software subscriptions as a percentage of total revenue would have been 23.9% for the three months ended March 31, 2020.

The balance of the increase of $2.1 million is primarily due to costs associated with increased development activity associated with nascent technologies and new solutions to address end-to-end data analysis and compliance needs of our customers. As a percentage of total revenue, research and development expenses increased to 14.7% for the three months ended March 31, 2020 compared to 10.1% for the three months ended March 31, 2019, driven in part by our expanded investment in developing our global compliance reporting solution.

As a percentage of total revenue, selling and marketing expenses increased to 27.3% for the three months ended March 31, 2020 compared to 21.5% for the same period in 2019.

Of this increase, 68.2% is due to an increase in stock-based compensation of $15.1 million for the three months ended March 31, 2020 over the same period in 2019. The balance of the increase of $7.1 million is primarily due to planned strategic investments in information technology infrastructure, business process reengineering and other initiatives to drive future operating leverage, as well as investments in employees and other systems and resources in support of our growth. Due to these factors, as a percentage of total revenue, general and administrative expenses increased to 42.2% for the three months ended March 31, 2020 compared to 20.7% for the same period in 2019.

Interest expense

  $ 924   $ 537   $ 387     72.1 %

        Interest expense increased $0.4 million, or 72.1%, to $0.9 million for the three months ended March 31, 2020 compared to $0.5 million for the same period in 2019. The increase is primarily due to interest of $0.2 million related to borrowings under the line of credit of $12.3 million in January 2020 to fund the initial purchase of a controlling interest in a tax software and content subscription provider in Brazil and general interest rate increases during the quarter, and due to the write-off of $0.2 million in deferred financing fees for extinguished debt in connection with the New Credit Agreement entered into on March 31, 2020.

Total revenue

  $ 321,500   $ 272,403   $ 49,097     18.0 %

        Revenue increased $49.1 million, or 18.0%, to $321.5 million in 2019 compared to $272.4 million in 2018. The increase in software subscriptions revenue of $40.0 million, or 17.0%, was primarily driven by $29.0 million in revenue growth derived from our existing customers and $11.0 million of revenue from new customers.

        The $9.1 million increase in services revenue is primarily driven by an increase of $5.3 million in software subscription-related services associated with the growth in subscription revenues, which includes new customers implementing our solutions and upgrading existing customers to newer versions of our solutions. In addition, our managed services offering experienced a $2.5 million increase in recurring services revenue over the prior year due to returns processing volume increases related to regulatory changes as customers expanded their tax filings into more jurisdictions.

        General and administrative expenses increased $12.1 million, or 20.5%, to $71.0 million in 2019 compared to $59.0 million in 2018. The increase was primarily due to planned strategic investments of $6.8 million in information technology infrastructure, business process reengineering and other initiatives to drive future operating leverage, as well as investments aggregating $3.7 million in employees and other systems and resources in support of our growth. Due to these factors, as a percentage of total revenue, general and administrative expenses increased to 22.1% in 2019 compared to 21.6% in 2018.

        For the year ended December 31, 2018, we recorded an impairment of $32.7 million for capitalized internal-use software previously utilized to provide cloud-based services to customers, net of accumulated amortization of $11.9 million. This impairment was related to a product strategy shift that resulted in this cloud offering no longer being made available for sale to customers after 2018. The capitalized development costs were deemed to be fully impaired due to the net book value of the asset exceeding its future expected cash flows.

        Provision for taxes decreased $1.8 million, or 109.2%, to an income tax benefit of $0.2 million in 2019 compared to $1.7 million in 2018. The decrease was primarily due to a $1.0 million charge in 2018 to establish deferred taxes for assets that were transferred to the United States from a taxing jurisdiction that had a 0% tax rate.

Seasonality and Quarterly Trends

        We have historically signed a higher percentage of software subscription agreements with new and existing customers in the fourth quarter of each year. This can be attributed to buying patterns typical in the software industry. Since most of our customer agreement terms are annual, agreements initially entered into in the fourth quarter will generally come up for renewal at that same time in subsequent years. As a result, customer agreement cancellations may have a higher concentration during the end of the year. In addition, typically the first and last quarters of the year tend to be higher volume sales periods. This seasonality is reflected in our revenues, though the impact to overall annual or quarterly revenues is minimal since we recognize subscription revenue ratably over the term of the customer contract. Additionally, this seasonality is reflected in commission expenses to our sales personnel and our partners.

        Our quarterly revenue has generally increased over the last two years primarily due to new sales to existing customers and sales to new customers. However, the pace of our revenue growth has not been consistent. Many of our customers are enterprise and large corporations and their purchase patterns can be sensitive to timing of budget decisions. Depending on such timing, these decisions can create volatility in the amount of business transacted by our salesforce and the amount of revenues recorded in each quarter. As such, certain periods may be less comparable due to the timing of our customers purchase patterns.

        Our operating expenses generally have increased over the two-year period due to increases in headcount and related expenses to support our growth. Quarterly fluctuations in our costs and expenses overall primarily reflect changes in our headcount, and other costs related to certain technology development projects and the development and scaling of our cloud solution. In particular, research and development expenses have fluctuated based on the timing of personnel additions, capitalized costs and related spending on product development. Increases in our sales and marketing expenses primarily reflect personnel additions and various sales and marketing initiatives, the timing of which may fluctuate from quarter to quarter. We anticipate our operating expenses will continue to increase in future periods as we invest in the long-term growth of our business.

        The Company has used stock-based compensation programs as a component of overall compensation expense for certain of its employees. Certain of these programs require the appreciation in value of our common stock to be recorded as compensation expense for services rendered by participants over the requisite service period for such awards at each measurement date. Beginning in the fourth quarter 2019 and continuing into 2020, intrinsic value has risen significantly as our proximity to an initial public offering has become more likely and as such, the amount of expenses recorded related to stock-based compensation have significantly increased our operating expenses over the past two quarters making period-over-period comparisons difficult. In particular, we estimate that we will record additional stock-based compensation expense of approximately $41.5 million during the quarter ended June 30, 2020 as well as an additional approximately $56.5 million for the period from July 1, 2020 to the date of this prospectus related to the conversion of our outstanding SARs to stock options in connection with this offering. We also expect to recognize approximately $44.0 million of stock-based compensation expense over the requisite service period of four years related to outstanding SAR awards. In addition, in connection with this offering, we expect to grant equity awards to certain of our employees, consultants and directors with a fair value of approximately $13.3 million as of the date of this prospectus, of which amount $8.3 million is expected to be recognized as stock-based compensation expense over the next twelve months. We expect that our stock-based compensation expense will be significantly higher relative to historical periods for the foreseeable future, and as a result, historical financial information is not necessarily indicative of our future results.

        During the fourth quarter of 2018, we recorded an impairment of $32.7 million for capitalized internal-use software previously utilized to provide cloud-based services to customers, net of accumulated amortization of $11.9 million. This impairment was related to a product strategy shift that

74

resulted in this cloud offering no longer being made available for sale to customers after 2018. The capitalized development costs were deemed to be fully impaired due to the net book value of the asset exceeding its future expected cash flows.

        Historical patterns should not be considered a reliable indicator of our future sales activity or performance.

Liquidity and Capital Resources

        As of December 31, 2019, we had cash and cash equivalents of $75.9 million and an accumulated deficit of $90.7 million. Our primary sources of capital to date have been from sales of our solutions and proceeds from bank lending facilities. We believe that our existing cash resources will be sufficient to meet our capital requirements and fund our operations for at least the next 12 months. Our existing credit facility, which was due to mature in November 2020, was refinanced on March 31, 2020 through borrowings pursuant to the New Credit Agreement, which involved a $175.0 million three-year term loan and a $100.0 million five-year line of credit. The term loan is required to be repaid upon consummation of this offering. No amounts are outstanding under the line of credit at May 31, 2020. In the event this offering is not consummated, we believe that cash flows from operations are sufficient to repay the outstanding borrowings. Further, we believe we have the ability to refinance our credit facility pursuant to the New Credit Agreement in the future should the need arise. However, if these sources are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity or debt securities. If we raise additional funds by issuing equity securities, our stockholders would experience dilution. Debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders. Additional financing may not be available at all, or in amounts or on terms unacceptable to us.

        The following table presents a summary of our cash flows for the periods indicated:

  $ 24,321   $ 16,036   $ 75,332   $ (10,587 )

        Operating Activities.    Cash provided by operating activities was $92.5 million for the year ended December 31, 2019 compared to $80.4 million for the same period in 2018, an increase of $12.1 million. This increase was primarily due to increased net income of $4.5 million, after adding back the 2018 impairment, increases in stock-based compensation of $4.1 million and a net increase in cash from operating assets and liabilities of $3.8 million. Cash used in operating activities was $6.4 million for the three months ended March 31, 2020 compared to cash provided by operating activities of $9.9 million for the same period in 2019, a decrease of $16.3 million. This change was primarily due to a net reduction in cash from operating assets and liabilities of $16.0 million. This reduction was primarily due to decreases in accrued and deferred compensation of $4.8 million, a reduction in deferred revenue of $7.6 million and a reduction in accounts receivable of $2.3 million. Accrued and deferred compensation decreased by $4.8 million due to payments for variable compensation for the three months ended March 31, 2020, increasing over the prior year comparable quarter by $2.7 million due to increases in headcount, and due to payments of $2.8 million for stock appreciation right redemptions in the first quarter of 2020 as compared to the same quarter of 2019.

75


Table of Contents

Deferred revenue decreased $7.6 million due to a $4.8 million decrease in non-recurring extended product support fees billed in the first quarter 2019 related to software subscription solutions retired during 2019. The balance of the deferred revenue reduction of $2.8 million, and the reduction in accounts receivable of $2.3 million are due primarily to modifications to billing frequencies requested by customers, primarily to align all the annual subscription billings for their subscription licenses to the same period. This results in a short-term reduction in deferred revenue, but no impact to revenue.

        Investing Activities.    Cash used in investing activities was $37.6 million for the year ended December 31, 2019 compared to $33.3 million for the same period in 2018, an increase of $4.3 million. This increase is due to investments focused on productivity enhancement associated with process automation and implementation of new tools. Cash used in investing activities was $21.7 million for the three months ended March 31, 2020 compared to $8.1 million for the same period in 2019, an increase of $13.5 million. This increase was primarily related to the acquisition of a controlling interest in Systax Sistema Fiscais LTD ("Systax"), a Brazilian transaction tax software and content subscription provider, for cash paid of $12.3 million during the quarter. For additional information on investing activities, see "Note 2 to Consolidated Financial Statements—Acquisition (unaudited)."

        Financing Activities.    Cash used in financing activities was $30.6 million for the year ended December 31, 2019 compared to $30.7 million for the same period in 2018, a decrease of $0.1 million. This decrease was primarily due to an increase in principal repayments of bank debt of $2.3 million, offset by an increase in cash collected with respect to customer funds obligations of $2.6 million. Cash provided by financing activities was $103.7 million for the three months ended March 31, 2020 compared to $12.4 million used for the same period in 2019, a change of $116.1 million. This change was due primarily to borrowings under the term loan of $175.0 million in connection with the New Credit Agreement entered into on March 31, 2020. The proceeds of the term loan were used to repay amounts outstanding under the Company's previous credit agreement of $61.7 million and pay related financing fees of $2.9 million, with the balance being used to fund a portion of a $123.0 million dividend to our stockholders on May 29, 2020.

        Debt.    As of December 31, 2019, we had a credit agreement consisting of a $65.0 million term loan, with $50.4 million outstanding, and a $40.0 million line of credit. Interest on outstanding borrowings accrued at a Base Rate plus an applicable margin (4.75% as of December 31, 2019) or London Interbank Offered Rate ("LIBOR") plus an applicable margin (2.69% as of December 31, 2019). On March 31, 2020, we entered into the $275.0 million New Credit Agreement consisting of a three-year $175.0 million term loan and a $100.0 million line of credit with a term of five years. Proceeds from the term loan were used to repay amounts outstanding under the Company's previous credit agreement of $61.7 million and pay related financing fees of $2.9 million, with the balance being used to fund a portion of a $123.0 million dividend to our stockholders on May 29, 2020. The term loan is required to be repaid with proceeds from this offering. Absent the occurrence of this offering, the term loan requires quarterly principal payments of $4.4 million beginning October 2020 with a balloon payment in March 2023. There were no amounts borrowed under the line of credit through May 31, 2020. As of May 31, 2020, the interest rate on the term loan was 2.50%.

Funds Held for Customers and Customer Funds Obligations

        We maintain trust accounts with financial institutions, which allows our customers to outsource their tax remittance functions to us. We have legal ownership over the accounts utilized for this purpose. Funds held for customers represents cash and cash equivalents that, based upon our intent, are restricted solely for satisfying the obligations to remit funds relating to our tax remittance services. Funds held for customers are not commingled with our operating funds.

        Customer funds obligations represent our contractual obligations to remit collected funds to satisfy customer tax payments. Customer funds obligations are reported as a current liability on our consolidated balance sheets as the obligations are expected to be settled within one year. Cash flows

related to changes in customer funds obligations liability are presented as cash flows from financing activities.

Off-Balance Sheet Arrangements

        We do not have any off-balance sheet arrangements, as defined by applicable regulations of the SEC, that are reasonably likely to have a current or future material effect on our financial condition, results of operations, liquidity, capital expenditures or capital resources.

Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

        We had cash and cash equivalents of $55.8 million and $75.9 million as of December 31, 2018 and 2019, respectively, and $40.4 million as of March 31, 2020. We maintain our cash and cash equivalents in deposit accounts and money market funds with financial institutions. Due to the short-term nature of these instruments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. Declines in interest rates, however, would reduce future interest income.

        We are exposed to risk related to changes in interest rates. Borrowings under the New Credit Agreement bear interest at rates that are variable. Increases in the bank prime or LIBOR rates would increase the interest rate on these borrowings.

        On March 31, 2020, we entered into the $275.0 million New Credit Agreement consisting of a three-year $175.0 million term loan and a $100.0 million line of credit with a term of five years. A portion of the proceeds from the term loan were used to repay amounts outstanding under the Company's previous credit agreement of $61.7 million. There were no amounts borrowed under the line of credit through May 31, 2020. Each change of one percentage point in interest rates would result in an approximate $1.75 million increase in our annual interest expense. Any debt we incur in the future may also bear interest at variable rates.

Foreign Currency Exchange Risk

        Our revenue and expenses are primarily denominated in U.S. dollars. For our foreign operations, the majority of our revenues and expenses are denominated in other currencies, such as the Canadian Dollar, Euro, British Pound, Swedish Krona and Brazilian Real. Decreases in the relative value of the U.S. dollar as compared to these currencies may negatively affect our revenue and other operating results as expressed in U.S. dollars. For the years ended December 31, 2018 and 2019 and the three months ended March 31, 2019 and 2020, approximately 1% of our revenues were generated in currencies other than U.S. dollars in each respective period.

77


Table of Contents

        We have experienced and will continue to experience fluctuations in our net income (loss) as a result of transaction gains or losses related to revaluing certain current asset and current liability balances that are denominated in currencies other than the functional currency of the entities in which they are recorded. We have historically recognized immaterial amounts of foreign currency gains and losses in each of the periods presented. We may in the future hedge selected significant transactions denominated in currencies other than the U.S. dollar as we expand our international operation and our risk grows. The acquisition of the controlling interest in Systax in January 2020 and the future purchase commitments associated with this acquisition are expected to increase our exposure to fluctuations of the Brazilian Real over time.

Inflation

        In the past two years, we do not believe that inflation had a material effect on our business, financial condition or results of operations. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm our business, financial condition and results of operations.

Internal Control Over Financial Reporting

        In connection with the audit of our consolidated financial statements, we identified three material weaknesses in our internal control over financial reporting during the two-year period ended December 31, 2019. These material weaknesses were due to (i) the lack of an effective review control over the completeness and accuracy of significant conclusions regarding the impact of the new revenue recognition guidance prescribed by ASC 606, (ii) incorrect applications of software capitalization models and untimely identification of impairments of capitalized software development costs and (iii) an insufficient process for the provision and governance of user access to financially significant systems that resulted in a lack of segregation of duties related to journal entries and cash disbursements. The material weaknesses resulted in several control deficiencies that could have the following effects:

        The material weaknesses relating to revenue recognition and capitalized software development costs resulted in errors that were not identified timely in conjunction with the issuance of our financial statements as of and for the years ended December 31, 2018 and 2019. These errors led to adjustments reflected in the 2019 and 2018 audited consolidated financial statements contained herein. We evaluated these errors under both quantitative and qualitative standards. No errors were identified with respect to the lack of segregation of user access to financially significant systems.

        A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis by a company's internal controls.

        Beginning in February 2020, we started specific efforts to remediate the material weaknesses described above, including the following:

78


Table of Contents

        We continue to implement new technology systems to automate certain processes, particularly with respect to revenue recognition. We expect these efforts to continue throughout 2020 and, in the interim, we will continue to employ enhanced review controls. We also plan to increase the education and training available to our management regarding new and revised accounting standards to aid in our efforts to remediate the material weakness regarding our implementation of ASC 606 and future accounting pronouncements. Our executive team in charge of reviewing potential impairments of capitalized software development costs will continue to meet quarterly in 2020 and thereafter. Finally, we are in the process of performing an overall review of user access for our core financial systems, which we expect may result in further segregation of duties. We also plan to periodically update our review of user access going forward.

        As we continue to implement these practices and prepare to meet the financial reporting requirements of a public company, we may make additional changes to our internal control over financial reporting. Additionally, in 2020, we expect to enhance our financial reporting risk assessment as part of evaluating our current control environment against a formal control framework consistent with applicable requirements for a public company.

Critical Accounting Policies and Estimates

        Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements. The preparation of these financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported amounts of revenue and expenses during the reporting periods. These estimates, assumptions and judgments are necessary because future events and their effects on our consolidated financial statements cannot be determined with certainty, and are made based on our historical experience and on other assumptions that we believe to be reasonable under the circumstances. These estimates may change as new events occur or additional information is obtained, and we may periodically be faced with uncertainties, the outcomes of which are not within our control and may not be known for a prolonged period of time. Because the use of estimates is inherent in the financial reporting process, actual results could materially differ from those estimates.

        We believe the following critical accounting policies affect our most significant judgments and estimates used in preparation of our consolidated financial statements:

79


Table of Contents

Revenue Recognition

        On January 1, 2018, we adopted ASC 606. Thus, the consolidated financial statements reflect ASC 606 for the years ended December 31, 2019 and 2018.

        Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration expected to be received in exchange for those products or services. We enter into contracts that can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. Revenue is recognized net of allowance for subscription and non-renewal cancellations and any taxes collected from customers, which are subsequently remitted to governmental authorities.

        Licenses for on-premise software subscriptions provide the customer with a right to use the software as it exists when made available to the customer. Customers purchase a subscription to these licenses, which includes the related software and tax content updates and product support. The updates and support, which are part of the subscription agreement, are essential to the continued utility of the software. Therefore, we have determined the software and the related updates and support to be a single performance obligation. Accordingly, when on-premise software is licensed, the revenue associated with this combined performance obligation is recognized ratably over the license term as these subscription services are provided for the duration of the license term. Revenue recognition begins on the later of the beginning of the subscription period or the date the software is made available to the customer to download. Our on-premise software subscription prices in the initial subscription year are higher than standard renewal prices. The excess initial year price over the renewal price ("new sale premium") is considered to be a material right. We recognize revenue associated with the material right over the estimated period of benefit to the customer, generally three years.

        Cloud-based subscriptions allow customers to use Company-hosted software over the contract period without taking possession of the software. The cloud-based offerings also include related updates and support. All services within the cloud-based contracts would consistently provide a benefit to the customer during the subscription period, thus the associated revenue is recognized ratably over the subscription period. Revenue recognition begins on the later of the beginning of the subscription period or the date the customer is provided access to the cloud-based services.

        Revenue from deliverable-based services is recognized as services are delivered. Revenue from fixed fee services is recognized as services are performed using the percentage of completion input method.

        We have elected the "right to invoice" practical expedient for revenue related to services that are billed on an hourly basis, which enables revenue to be recognized as the services are performed.

        We have determined that the methods applied to measuring our progress toward complete satisfaction of performance obligations recognized over time are a faithful depiction of our transfer of control of software and services to customers.

Significant Judgments

        Contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. Identification of the amortization periods of material rights and contract costs requires significant judgement by management.

Contract Balances

        Timing of revenue recognition may differ from the timing of invoicing customers. A receivable, or contract asset, is recorded in the consolidated balance sheet when customers are billed related to revenue to be collected and recognized for subscription agreements as there is an unconditional right to

80


Table of Contents

invoice and receive payment in the future related to these subscriptions. A receivable and related revenue may also be recorded in advance of billings to the extent services have been performed and we have a right under the contract to bill and collect for such performance. Subscription-based customers are generally invoiced at the beginning of each annual subscription period. A contract liability is recorded as deferred revenue on the consolidated balance sheet when subscription-based customers are billed in advance of performance obligations being satisfied, and revenue is recognized subsequent to invoicing ratably over the subscription period or over the amortization period of material rights.

        Deferred sales commissions earned by our sales force and certain sales incentive programs and vendor referral agreements are considered incremental and recoverable costs of obtaining a contract with a customer. An asset is recognized for these incremental contract costs and reflected as deferred commissions in the consolidated balance sheet. These contract costs are amortized on a straight-line basis over a period consistent with the transfer of the associated product and services to the customer, which is generally three years. Amortization of these costs are included in selling and marketing expense in the consolidated statements of comprehensive income (loss). We periodically review these contract assets to determine whether events or changes in circumstances have occurred that could impact the period of benefit of these assets. There were no impairment losses recorded for the periods presented.

Payment Terms

        Payment terms and conditions vary by contract, although our terms generally include a requirement of payment within 30 days. In instances where the timing of revenue recognition differs from the timing of payment, we have determined that our contracts do not include a significant financing component. The primary purpose of invoicing terms is to provide customers with simplified and predictable ways of purchasing products and services, not to receive financing from customers or to provide customers with financing.

Stock-Based Compensation

        We apply the provisions of ASC 718, Compensation—Stock Compensation, for the award of equity-based instruments. The provisions of ASC 718 require a company to measure the fair value of stock-based compensation as of the grant date of the award. We have stock options and SARs (collectively, the "awards") outstanding that are subject to guidance set forth in ASC 718. Our board of directors intends all awards granted to be exercisable at a price per share not less than the per share fair value of the Company's common stock underlying such awards on the date of grant. Stock-based compensation expense reflects the cost of employee services received in exchange for the awards.

        SARs are accounted for as liabilities under ASC 718 and, as such, we recognize stock-based compensation expense by remeasuring the SARs at the end of each reporting period and accruing the portion of the requisite service rendered at that date. As a nonpublic entity, we have elected to measure SARs based on their intrinsic values. Management measures the intrinsic value of a SAR as the difference between the fair value of the Company's non-voting common stock less the grant date fair value of the underlying shares as this is the value the SAR participant can derive from exercise of the SAR award. The fair value of the Company's common stock is determined periodically by the board of directors with the assistance of management and a third-party valuation firm. Management continues to record changes in the intrinsic value of the SARs in 2020 up to the date on which we are considered to have become a public entity. Management will record the change in accounting policy based on the application of ASC 718. We will record any incremental increase in fair value of the Converted SARs (as defined below) resulting from the modification as compensation expense at the time of the exchange, which is contingent upon the occurrence of this offering. Upon modification, the Converted SARs will no longer be recorded as a liability under ASC 718 and the accumulated liability balance will be reclassified to stockholders equity. The unvested portion of the Converted SAR liability at the offering date will be amortized over the remaining service period of the Converted SARs as

81


Table of Contents

compensation expense. Management estimates the fair value of the Converted SARs at the offering date to be approximately $197.0 million, of which approximately $153.0 million will be vested. At this value, management would record an estimated additional compensation expense of approximately $98.0 million for vested Converted SARs from April 1, 2020 to the offering date, including the impact of the change in accounting. The remaining approximate $44.0 million of unvested Converted SAR liability will be recognized as compensation expense over the remaining service period through 2025, including the impact of the change in accounting. Outstanding SARs are included in deferred compensation, current and deferred compensation, net of current portion in the consolidated balance sheets.

        SAR participants were offered the option to either redeem their SARs upon the occurrence of the offering or amend their SARs pursuant to which, upon effectiveness of our 2020 Plan to occur on the effective date of this registration statement, such SARs will become options to purchase shares of Class A common stock under the 2020 Plan. Effective July 13, 2020, this offer period ended and all SAR participants eligible to receive the offer accepted and will have their outstanding SARs converted to stock options with equivalent terms under the 2020 Plan (the "Converted SARs") effective upon this offering. This is considered a modification of these SAR awards.

        Converted SARs with either no expiration date or that expire during calendar year 2020 will convert to options and be automatically exercised into shares (the "Auto Exercise New Options"). Shares issued in connection with the Auto Exercise New Options will be net of the number of shares of common stock necessary to satisfy the aggregate exercise price and the tax withholding obligation of such options. The Auto Exercise New Option participants also had the ability to require us to repurchase all or a portion of the shares remaining after this reduction on the offering date for cash based on the offering price.

        Due to the option holders having the right to require us to repurchase shares issued in connection with option exercises after six months of issuance, the options are classified as temporary equity and reflected in options for redeemable shares on the consolidated balance sheets at their redemption value as of the end of each balance sheet measurement period. Changes as a result of remeasurement of the redemption value of options for redeemable shares are recorded as adjustments to accumulated deficit.

        As of December 31, 2019, we had approximately $3.9 million of total unrecognized stock-based compensation expense, which we expect to recognize over a period of approximately three to five years. As of March 31, 2020, we had approximately $16.8 million of total unrecognized stock-based compensation.

Common Stock Valuations

        Following the closing of this initial public offering, the fair value per share of our common stock for purposes of determining stock-based compensation will be the closing price of our common stock as reported on the applicable grant date.

        The fair value of the common stock underlying the awards is determined by the board of directors with assistance from management and an independent third-party valuation firm. The determination of value uses the market and income approaches, with an adjustment for marketability discount in arriving at the per share fair value (the "valuation methodology"). Under the market approach, the guideline public company method is used, which estimates the fair value of our Company based on market prices of stock of guideline public companies. The income approach involves projecting the future benefits of owning an asset and estimating the present value of those future benefits by discounting them based upon the time value of money and the investment risks associated with ownership.

        At the end of 2019, due to the consideration by our board of directors of pursuing an initial public offering of the Company's common stock during 2020, the valuation methodology began to consider the impact of such an event on the value of the Company's common stock underlying the awards. As we approach the offering, we expect this will result in an increase in the intrinsic value of the awards that

82


Table of Contents

will correspondingly result in increases to compensation expense in the consolidated comprehensive statements of income during 2020 that exceed historical results. For additional information, see "Seasonality and Quarterly Trends."

Software Development Costs

Internal-Use Software

        We follow ASC 350-40, Goodwill and Other, Internal-Use Software, to account for development costs incurred for the costs of computer software developed or obtained for internal use. ASC 350-40 requires such costs to be capitalized once certain criteria are met. Capitalized internal-use software costs are primarily comprised of direct labor, related expenses and initial software licenses. ASC 350-40 includes specific guidance on costs not to be capitalized, such as overhead, general and administrative and training costs. Internal-use software includes software utilized for cloud-based services as well as software for internal systems and tools. Costs are capitalized once the project is defined, funding is committed and it is confirmed the software will be used for its intended purpose. Capitalization of these costs concludes once the project is substantially complete and the software is ready for its intended purpose. Post-configuration training and maintenance costs are expensed as incurred. Internal-use software available for its intended use is included in internal-use software developed in property and equipment in the consolidated balance sheets and is depreciated over periods between three to five years. Depreciation expense for internal-use software utilized for cloud-based services and for software for internal systems and tools is included in cost of software subscription revenues, and depreciation expense, respectively, in the consolidated statements of comprehensive income (loss).

        We review the carrying value of internal-use software, for impairment whenever events or changes in circumstances indicate that the carrying amount of such software may not be fully recoverable. Whenever such events or circumstances are present, an impairment loss equal to the excess of the asset carrying value over its fair value, if any, is recorded.

Software Developed for Sale

        The costs incurred for the development of computer software to be sold, leased or otherwise marketed are capitalized in accordance with ASC 985-20, Costs of Software to be Sold, Leased or Marketed, when technological feasibility has been established. Technological feasibility generally occurs after completion of all planning, design, coding and testing activities that are necessary to establish that the product can be produced to meet its design specifications, including functions, features and technical performance requirements. The establishment of technological feasibility is an ongoing assessment of judgment by management with respect to certain external factors, including, but not limited to, anticipated future revenues, estimated economic life and changes in technology. Capitalized software includes direct labor and related expenses for software development for new products and enhancements to existing products and acquired software.

        Amortization of capitalized software development costs begins when the product is available for general release. Amortization is provided on a product-by-product basis using the straight-line method over periods between three to five years. Unamortized capitalized software development costs determined to be in excess of the net realizable value of the product are expensed immediately.

        Capitalized software costs are subject to an ongoing assessment of recoverability based on anticipated future revenues and changes in software technologies. At each balance sheet date, unamortized capitalized software costs are compared to the net realizable value of the related product. The carrying value of the related assets are written down to the net realizable value to the extent the unamortized capitalized costs exceed such value. The net realizable value is the estimated future gross revenues from the related product reduced by the estimated future costs of completing and disposing of such product, including the costs of providing related maintenance and customer support.

Goodwill

        Goodwill represents the excess of the purchase price over the fair value of net tangible and intangible assets acquired in a business combination. We evaluate goodwill for impairment annually at December 31 and whenever events or circumstances make it more likely than not that impairment may have occurred. We have determined that our business comprises one reporting unit. We have the option to first assess qualitative factors to determine whether events or circumstances indicate it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, in which case a quantitative impairment test is not required.

        The quantitative goodwill impairment test is performed by comparing the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not impaired. An impairment loss is recognized for any excess of the carrying amount of the reporting unit's goodwill over the fair value up to the amount of goodwill allocated to the reporting unit. Income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit are considered when measuring the goodwill impairment loss, if applicable.

Recent Accounting Pronouncements

        A discussion of recent accounting pronouncements is included in note 1 to our audited consolidated financial statements included elsewhere in this prospectus.

JOBS Act

        As a company with less than $1.07 billion in revenue during our last fiscal year, we qualify as an "emerging growth company," as defined in the JOBS Act. An emerging growth company may take advantage of reduced reporting requirements that are otherwise applicable to public companies. These provisions include:

        We may take advantage of these provisions until the last day of our fiscal year following the fifth anniversary of the completion of this offering. However, if certain events occur prior to the end of such five-year period, including if we become a "large accelerated filer," our annual gross revenue exceeds $1.07 billion or we issue more than $1.0 billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company prior to the end of such five-year period.

        We have elected to take advantage of certain of the reduced disclosure obligations in this registration statement and may elect to take advantage of other reduced reporting requirements in future filings. As a result, the information that we provide to our stockholders may be different from what you might receive from other public reporting companies in which you hold equity interests.

        In addition, under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies.

BUSINESS

Overview

        Our vision is to accelerate global commerce, one transaction at a time.

        Vertex delivers comprehensive tax solutions that enable global businesses to transact, comply and grow with confidence. Companies with complex tax operations rely on Vertex to automate their end-to-end indirect tax processes. Indirect tax is the largest corporate tax category, encompassing sales tax, seller's use tax, consumer use tax and VAT, among others. Indirect tax accounts for more than $3.5 trillion of annual tax revenue, which is 2.5 times the amount of corporate income taxes, according to the 2019 OECD Tax Database. Our software, content and services address the increasing complexities of global commerce and compliance by reducing friction, enhancing transparency and enabling greater confidence in meeting indirect tax obligations. As a result, our software is ubiquitous within our customers' business systems, touching nearly every line item of every transaction that an enterprise can conduct. Today, we have more than 4,000 customers, including over half of the Fortune 500, and provide our customers with tax support in over 130 countries.

        Tax complexity is driven by the number of jurisdictions, products, distribution channels and systems of record within an organization. Each transaction must be tax-assessed for compliance purposes in real time and indirect taxes generally require filing each month, in every jurisdiction in which a company does business. Despite these complexities, there are still businesses that attempt to manage the tax lifecycle through a patchwork of static tax rate tables in spreadsheets, home-built systems or business applications, such as ERP software, that were not designed for complex tax management. Each of these approaches relies heavily on finance personnel or outside professional services.

        The rapid changes taking place in today's global business, technology and regulatory environments are having a compounding effect on the complexity of indirect tax management. As companies expand their business models, enter new geographies and extend their distribution channels, they widen the aperture of their indirect tax obligations. Additionally, as they expand their core offerings to incorporate new digital products and services, they are increasingly impacted by new tax regulations being pursued by jurisdictions. For example, in the United States, nearly 40 states have now enacted marketplace facilitator regulations, requiring online marketplaces to collect and remit taxes for first- and third-party sales on their websites. This complexity demands intelligent solutions that enable businesses to satisfy tax obligations and support growth opportunities.

        We have pioneered tax technology for over 40 years. We first began electronic delivery of tax rules in the early 1980s and we first sold transaction tax processing software in 1982. Today, our software enables tax determination, compliance and reporting, tax data management and document management with powerful pre-built integrations to core business applications used by most companies, particularly those applications that have a significant impact on global commerce. Our software is fueled by over 300 million data-driven effective tax rules and supports indirect tax compliance in more than 19,000 jurisdictions worldwide. In order to maintain the quality of our content, our team includes many global tax and regulatory experts from industry and the public sector, who deliver monthly updates to our tax content, which are then incorporated directly into our software. Our solutions can be deployed on-premise, in the cloud, or both, with implementation services available to enable optimal customer outcomes and satisfy unique business requirements.

        Our customers include the majority of the Fortune 500, as well as a majority of the top 10 companies by revenue in multiple industries such as retail, technology and manufacturing, in addition to leading marketplaces. As these companies expand geographically and pursue omnichannel business models, their tax determination and compliance requirements increase and become more complex. Our trusted brand and strong relationships with our customers enable us to capitalize on these sustainable organic growth opportunities.

        Our partner ecosystem is a differentiating, competitive strength in both our software development and our sales and marketing activities. We integrate with key technology partners that span ERP, CRM, procurement, billing, POS and eCommerce. These partners include Adobe/Magento, Coupa, Microsoft Dynamics, NetSuite, Oracle, Salesforce, SAP, SAP Ariba, Workday and Zuora. We also collaborate with numerous accounting firms who have built implementation practices around our software to serve their customer base.

        We believe that global commerce and compliance environment provides durable and accelerating growth opportunities for our business. We generated revenue of $272.4 million and $321.5 million in 2018 and 2019, respectively, and $74.6 million and $89.2 million for the three months ended March 31, 2019 and 2020, respectively. We had a net loss of $6.1 million and net income of $31.1 million in 2018 and 2019, respectively, and net income of $7.3 million and a net loss of $29.1 million for the three months ended March 31, 2019 and 2020, respectively. Adjusted EBITDA was $61.5 million and $67.9 million in 2018 and 2019, respectively, and $15.6 million and $15.3 million for the three months ended March 31, 2019 and 2020, respectively. Additionally, we generated net cash provided by operating activities of $80.4 million and $92.5 million in 2018 and 2019, respectively, and $9.9 million and $(6.4) million in the three months ended March 31, 2019 and 2020, respectively. Our free cash flow was $47.1 million and $54.9 million in 2018 and 2019, respectively, and $1.8 million and $(15.8) million in the three months ended March 31, 2019 and 2020, respectively. Adjusted EBITDA and free cash flow are non-GAAP financial measures. For more information about how we use these non-GAAP financial measures in our business, the limitations of these measures and reconciliations to the most directly comparable GAAP measures, see "Prospectus Summary—Summary Consolidated Financial and Operating Information." In connection with the offering, we will convert from an S Corporation to a C Corporation, which will result in net income of the Company being taxed at the corporate level. For additional information on the effect of such conversion, see "Prospectus Summary—Summary Consolidated Financial and Operating Information."

Industry Background

Indirect taxes are significant and growing revenue streams for governments around the world

        Indirect taxes are part of everyday commerce in many countries—they are levied on items such as food, clothing, business supplies and even data transmissions from mobile phones. According to the 2019 OECD Tax Database, more than $3.5 trillion of indirect taxes were collected by national, state and local governments around the world in 2018, which is 2.5 times the amount of corporate income taxes collected. Indirect taxes on goods and services represented more than 10% of GDP for OECD countries in 2018 and governments continuously seek new ways to increase this revenue stream. In the United States, sales and use taxes are the largest component of indirect taxes. According to OECD Revenue Statistics, the United States collected more than $800.0 billion in tax revenue from goods and services taxes in 2018.

Tax reporting and compliance pose tenacious challenges for all businesses

        In today's global economy, indirect taxation is highly nuanced and growing in its complexity for most businesses. In order to calculate taxes accurately, enterprises must identify every jurisdiction in which they operate, determine and maintain the applicable rates for each of those jurisdictions and map the applicable taxability to the products and services they deliver. Cross-border transactions increase the complexity of taxes. Understanding the variables surrounding transactions and how they change applicable taxes becomes difficult for tax departments to manage given the volume of purchasing, sourcing and sales activities conducted by large enterprises.

        Indirect tax returns generally need to be filed on a monthly basis and noncompliance exposes companies to significant monetary liability, poor customer experiences and reputational risk. Tax audits can look back many years, creating a greater level of accountability for managing tax data than for

typical business data. Additionally, it is not unusual for a large enterprise to have a substantial number of tax audits across numerous jurisdictions ongoing at any point in time. Each audit may require detailed traceability to individual transactions to defend historical tax positions taken.

Dynamic business, regulatory and technology drivers have a compounding effect on tax compliance

        We believe that trends in the digital economy are accelerating the need for adoption of sophisticated tax solutions among a broader and growing number of enterprises and global commerce platforms.

Legacy approaches are insufficient

        Over the past several decades, many tax departments have addressed their indirect tax needs by relying on a patchwork of static tax rate tables in spreadsheets, home-built systems or business applications not designed for tax compliance. Each requires heavy reliance on finance personnel or outside professional services. As taxation becomes more complicated, we believe these approaches will begin to fracture as they are error-prone, inefficient and cannot scale, thus increasing exposure to fines, raising reserves and heightening the risk of tax audits across multiple jurisdictions.

Our Opportunity

        We believe the total addressable market for solutions that enable global commerce and compliance is robust, global and growing. We estimate our addressable market among global enterprises and other businesses with greater than $1.0 million in annual sales to be over $7.0 billion in the United States. We believe this potentially understates our total addressable market because it does not include businesses domiciled outside of the United States.

        We calculate our addressable market size by segmenting all companies domiciled in the United States across all industries by annual U.S. sales revenues. For each of the companies with greater than $1.0 million in annual sales, we then apply an estimate of total potential annual spend per company for indirect tax technologies, including tax determination, compliance, tax data management and document management, based on our average selling price estimates.

Key Benefits of Our Solutions

        We deliver comprehensive tax solutions that automate end-to-end indirect tax processes for enterprises and mid-market companies with complex tax operations. Our software includes tax determination, compliance and reporting, tax data management and document management fueled by our powerful and proprietary content database, which includes over 300 million data-driven effective tax rules supporting indirect tax compliance in more than 19,000 jurisdictions worldwide. Our solutions also include powerful pre-built integrations to core business applications, such as SAP and Oracle.

        Our solutions deliver the following key benefits to our customers:

        Comprehensive, efficient and accurate indirect tax management.    Our solutions provide our customers with powerful tools to manage their end-to-end indirect tax obligations across determination, documentation, reporting and remittance. Our solutions move customers away from manual and inconsistent processes, spreadsheets and home-built solutions and enable them to manage their indirect tax obligations accurately and efficiently, while reducing risk with richer documentation and support for ongoing compliance and reporting requirements.

        Reduction in tax audit risk and tax audit-induced costs.    We believe that customers implement our solutions to increase accuracy and transparency in supporting the tax audit process, and to lower their overall costs of tax audit defense. This is driven by rich documentation and data support during tax audit discovery, which can mitigate tax audit-related adjustments and fines. The accuracy and ease of using our software also allows finance and tax teams to redistribute their time and effort towards higher return on investment initiatives such as strategic planning and tax audit defense, creating meaningful expansion in productivity.

        Wide jurisdiction coverage to support geographic expansion.    Economic nexus for indirect taxes is often based on the geographic location of either operations or sales. We maintain expansive coverage of jurisdictions and continually update our global content database, allowing our customers to expand their operations around the world while maintaining compliance with the relevant indirect tax laws of each jurisdiction.

        Support of new business models.    As digital transformation continues to change our economy, many enterprises are adopting new business models and incorporating new technology in their products and operations to fuel growth, including diversified supply chains and omnichannel retail strategies. Many of these digital transformations result in new, complex indirect tax challenges. For example, data transmissions from internet-connected devices are subject to telecom taxes, which are often new and unfamiliar obligations to traditional manufacturers and retailers.

Our Tax Content

        All of our software and solutions are underpinned by our proprietary content database, which currently supports over 300 million effective tax rules. We employ over 70 tax-content professionals residing in the United States, United Kingdom, Amsterdam, Brazil and Belgium who continually update and maintain this extensive database of content. Our content is a key component of our software subscriptions. Its quality and accuracy are critical to the longevity of our customer subscriptions. On a monthly basis, our content team combines legislative research, analysis, technical logic and automation to embed updated rules into our software. Unlike many enterprise software solutions where maintenance and support is focused solely on periodic technology upgrades, our monthly updates are a critical element of allowing our customers to ensure that they are utilizing the latest tax changes to accurately calculate their indirect taxes.

Our Technology

        Our software and solutions are built upon a robust set of technology capabilities designed for the flexibility, configurability, speed and scale to handle the most complex tax scenarios and processing volumes and interoperability to core business applications.

        Real-Time Engine.    Our real-time engine determines the appropriate tax rules to apply to a line item in a transaction through a sequence of real-time processes that combine tax algorithms and tax content with transaction line item level detail. Combining tax content stored as structured data with sequencing and decision tree logic results in one or more individual tax rules that are applied to each line item in a transaction. This is built within memory and cached for performance. The in-memory processes of the core calculation engine are tuned to accommodate high volume and complex transactions at speed and scale.

        Configuration.    Our solutions are built to be highly configurable. Through our graphical user interfaces, users can configure and map their taxability to ensure the correct tax rules are executed. Our flexibility in configuration also extends to users who can create their own taxability rules, as appropriate. These user-defined taxability rules act as an override providing flexibility, to ensure that non-standard tax scenarios and processes can be addressed. Additionally, users can augment transactions entering and exiting the engine by building their own logic through our drag and drop experience. This logic is saved to then execute within the engine.

        Tax Geography.    Tax accuracy depends on detailed location information for where a transaction is occurring. We designed and created a proprietary solution for tax jurisdiction identification that leverages industry geographic information system tools and geospatial data. With our proprietary technology we are able to create and map multiple tax jurisdictions for a particular location and assign a unique identifier to each location so that it can be used by the engine to allow for higher accuracy. This technology is highly relevant to emerging economic shifts, such as the sharing economy, where the physical nexus of transactions is unclear, such as ride-sharing services.

        Security.    Our application security framework allows our customers to define how users can interact with sensitive enterprise data and how they are authorized to use certain aspects of our software. Users are mapped to a set of predefined roles and we provide our customers with the ability to create user-defined roles. User-defined role-based access can be defined on a screen-by-screen level and further refined with read and/or write privileges.

We also support service providers such as outsourcing and accounting firms who use our technology to calculate tax and file tax returns for their end-customers. While we include these marketplaces and service providers in our customer counts, the tens of thousands of their end-customers are not included in our customer counts.

        As of March 31, 2020, we had over 4,000 customers and our ARR per customer was over $70,000. While most of our revenue is currently generated by customers domiciled in the United States, many of our customers are multinational organizations with global business operations. We also provide tax software solutions outside the United States, primarily in Europe. No single customer represented more than 10% of our total revenue for the year ended December 31, 2019 or the three months ended March 31, 2020.

        Our success has resulted in part from our proprietary methodologies, software, reusable knowledge capital and other intellectual property rights. We rely on a combination of copyright, trademark and trade secret law, as well as contractual restrictions such as confidentiality and non-compete provisions to protect our intellectual property rights, including our brand, technology and confidential information. We have policies related to confidentiality, ownership, and the use and protection of our intellectual property. We also enter into confidentiality and invention assignment/proprietary rights agreements with our consultants, employees and other third parties as appropriate that protect and control access to our intellectual property, and we enforce these agreements if necessary. We recognize the value of our intellectual property in the marketplace and vigorously identify, create and protect it. We believe the innovation of our employees and our continued enhancement of the features and functionality of our solutions is the keystone of our success.

        Despite our efforts to protect our proprietary technology, confidential information and our intellectual property rights, unauthorized parties may attempt to copy or obtain and use our technology to develop applications with the same functionality as our applications, and policing unauthorized use of our technology and intellectual property rights may be difficult and may not be effective.

        We expect that software and other applications in our industry may be subject to third-party infringement claims as the number of competitors grows and the functionality of applications in different industry segments overlaps, and we may face such claims.

Regulation

        Our software and solutions rely on a range of complex laws and regulations relating to our customers' sales and use transactions and business operations. We aggregate information regarding tax rates, rules and regulations obtained from taxing jurisdictions and use that data within our software and solutions to calculate transaction taxes, prepare and file tax returns, and remit taxes on behalf of our customers. Our long term success is based on our monitoring and understanding this legal and regulatory landscape.

        We have an established an information security program that includes annual security training to help ensure that consultants and employees are aware of our legal and contractual obligations to protect us and our customer data. We also use privacy statements to provide notice to customers of our privacy practices, as well as provide them with the opportunity to furnish instructions with respect to the use of their personal information.

        We use security controls to help protect customer and employee data from loss, misuse and unauthorized alteration. We use technical, logical and procedural measures, such as multi-factor authentication, which are designed to help detect and prevent fraud and misuse of customer data. Whenever customers transmit their data to us, we follow current industry standards to encrypt the data as it is transmitted to us and when we store it. We work to protect our systems from unauthorized internal or external access using numerous commercially available computer security products as well as internally developed security procedures and practices.

Employees & Culture

        Our culture is the foundation of everything we do, guided by a common purpose to build trusted relationships at work, in business and in our communities. We strive to be a values-driven employer of choice who attracts, retains and inspires talented professionals to achieve their full potential. We have been recognized as one of the best places to work in Philadelphia for the past five years according to The Philadelphia Inquirer. We create and nurture an engaging work environment that embodies our core values of collaboration, performance, integrity, innovation and fun, and we actively support our employees' participation in community service and philanthropy.

        As of December 31, 2019, we had approximately 1,100 full-time employees. Of these employees, 95% were based in the United States, 4% based in Europe and 1% in Latin America. We believe we have a strong relationship with our employees and we have not experienced any work stoppages.

Facilities

        Our corporate headquarters, which includes our operations and innovation lab, is located in King of Prussia, Pennsylvania, and consists of approximately 189,502 square feet of space under a lease that expires on September 30, 2028.

        We also lease offices in Sarasota, Florida; Naperville, Illinois; London, United Kingdom; Amsterdam and Maastricht City, The Netherlands; Frankfurt, Germany; Sao Paulo, Brazil; Chennai, India; and Cork, Ireland.

Legal Proceedings

        From time to time, we may be involved in various legal proceedings arising from the normal course of business activities. We are not presently a party to any litigation the outcome of which we believe, if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, cash flows or financial condition.

Director Independence and Controlled Company Exemption

        Our board of directors has undertaken a review of its composition, the composition of its committees and the independence of each director.

103


Table of Contents

Robert and Rick Stamm, representing four of our eight directors, do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is "independent" as that term is defined under the applicable rules and regulations of the SEC and the listing requirements and rules of the Nasdaq Global Market. In making this determination, our board of directors considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director.

        Because the parties to the Stockholders' Agreement will own more than 50% of the voting power of our common stock after this offering, we are considered to be a "controlled company" for purposes of the Nasdaq Global Market listing requirements. As such, we are permitted, and have elected, to opt out of the Nasdaq Global Market listing requirements that would otherwise require our board of directors to be comprised of a majority of independent directors and require our nominating and corporate governance committee to be comprised entirely of independent directors. Accordingly, you may not have the same protections afforded to stockholders of companies that are subject to all of the Nasdaq Global Market corporate governance requirements. See "Risk Factors—Risks Related to this Offering and Ownership of our Class A Common Stock—We are a "controlled company" within the meaning of the rules of the Nasdaq Global Market and, as a result, expect to qualify for, and intend to rely on, exemptions from certain corporate governance requirements. You will not have the same protections afforded to stockholders of companies that are subject to such requirements."

Board of Directors, Committees and Executive Officers

Composition of Board of Directors

        Our board of directors currently consists of eight members. Our amended and restated certificate of incorporation and amended and restated bylaws will provide that the authorized number of directors shall be fixed from time to time by a resolution of the majority of our board of directors.

Term and Class of Directors

        Upon the effectiveness of the registration statement of which this prospectus forms a part, our board of directors will be divided into three staggered classes of directors of the same or nearly the same number. At each annual meeting of stockholders, a class of directors will be elected for a three-year term to succeed the directors of the same class whose terms are then expiring. The terms of the directors will expire upon election and qualification of successor directors at the annual meeting of stockholders to be held during the years 2021 for the Class I directors, 2022 for the Class II directors and 2023 for the Class III directors.

        Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class shall consist of one-third of the directors. The division of our board of directors into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control.

Term of Executive Officers

        Each executive officer is appointed and serves at the discretion of the board of directors and holds office until his or her successor is elected and qualified, or until his or her earlier resignation or removal.

2019 Salaries

        The named executive officers receive a base salary to compensate them for services rendered to the company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive's skill set, experience, role and responsibilities. In early 2019, the board of directors approved increases to the annual base salaries of our named executive officers as set forth in the table below. Mr. DeStefano's base salary was determined following review of a market analysis prepared by Aon, our independent compensation consultant, of chief executive officer compensation for comparable companies in our industry. The 2019 base salaries for Ms. Butler and Mr. Rowland were determined in connection with our annual performance review process for all employees.

Cash-Based Incentive Compensation

        2019 Annual Bonus.    We maintain an annual bonus plan (the "Organizational Bonus Plan"), which is designed to motivate and reward our employees, including our executives and named executive officers, for achievements relative to financial, non-financial and individual performance goals. For 2019, financial performance accounted for 80% of the bonus opportunity and was based on achievements relative to our three most important financial metrics (revenue, pre-tax net income and adjusted cash from operations ("ACFO")). The non-financial metrics for 2019 were based on our progress against critical business objectives and accounted for 20% of the bonus opportunity. Individual performance ratings for the year are also considered when determining awards under the Organizational Bonus Plan.

        Each named executive officer has a target bonus opportunity under the Organizational Bonus Plan, defined as a percentage of annual base salary. For 2019, the target bonuses for our named executive officers were 80% for Mr. DeStefano, 40% for Ms. Butler and 40% for Mr. Rowland. In February 2020, our compensation committee assessed achievement against the financial and non-financial metrics described above and the board of directors approved funding the bonus pool at 117.4% of the targeted Organizational Bonus Plan opportunity for 2019.

        The actual annual cash bonuses awarded to each named executive officer for 2019 performance are set forth above in the Summary Compensation Table in the column entitled "Non-Equity Incentive Plan Compensation".

        Multi-Year Bonus Plans.    In addition to the annual Organizational Bonus Plan, we maintain multi-year cash bonus plans for our most senior executives, including our named executive officers, and other key employees. The target bonuses, expressed as a percentage of annual base salary, for our named executive officers under the multi-year cash bonus plans are 50% for Mr. DeStefano and 30% for each of Ms. Butler and Mr. Rowland.

        In early 2017, Mr. DeStefano and Ms. Butler were granted awards under our 2010 Long-Term Rewards Plan with performance measured over the three-year period from January 1, 2017 to December 31, 2019. These awards were eligible to be earned based on revenue, pre-tax net income and ACFO growth over the performance period. Following the end of the performance period, the compensation committee assessed growth with respect to these financial metrics over the performance

period and approved bonuses for all participants in the 2010 Long-Term Rewards Plan, including the named executive officers. The actual cash bonuses earned by Mr. DeStefano and Ms. Butler under the 2010 Long-Term Rewards Plan for the performance period ending in 2019 are set forth above in the Summary Compensation Table in the column entitled "Non-Equity Incentive Plan Compensation."

        Effective January 2018, we adopted the 2018 Long-Term Rewards Plan for performance periods beginning on and after January 1, 2018. In early 2019, the named executive officers were granted awards under the 2018 Long-Term Rewards Plan for a three-year performance period from January 1, 2019 to December 31, 2021. These awards are scheduled to be earned based on the company's achievements against key financial metrics, including revenue, pre-tax net income, and ACFO at the end of the performance period. Amounts earned by the named executive officers with respect to these awards will be reported in the Summary Compensation Table in the year earned.

Equity Compensation

        Our named executive officers have been granted stock appreciation rights ("SARs"). SARs generally entitle their holder, upon exercise, to receive from us an amount in cash equal to the appreciation of the shares subject to the award between the grant date and the exercise date. The SARs generally vest with respect to 50% of the award on the second anniversary of the applicable grant date and as to 50% of the award on the fifth anniversary of the applicable grant date, subject to the holder's continuous service to the company through each vesting date. SARs are exercisable upon 50% vesting or upon the occurrence of certain triggering events; provided that SAR holders are limited to exercising no more than 25% of their vested SARs in any given year and provided further that SAR exercises are limited each year to the proportion of vested SARs to the total units outstanding multiplied by adjusted net cash from operating activities.

        The following table sets forth the SARs granted to our named executive officers during 2019 as the long-term equity incentive component of our compensation program. These SARs were granted under our Third Amended and Restated 2007 Stock Appreciation Rights Plan (the "2007 Plan") with exercise prices equal to the fair market value of our common stock on the date of grant, as determined by the board of directors, and subject to our standard vesting schedule described above.

        Treatment of Equity Awards in Connection with this Offering.    In connection with this offering, holders of outstanding SARs were offered the opportunity to amend outstanding SARs, whether vested or unvested, so that they become options to purchase shares of our Class A common stock. These options will cover an equal number of shares as the amended SARs and have an exercise price per share equal to the base price of an amended SAR, subject to the 3-for-1 forward stock split that will occur in connection with this offering. For additional information regarding the amendment of outstanding SARs, please see the section titled "Incentive Compensation Plans—2007 Stock Appreciation Rights Plan" below. We expect that all of the eligible SARs held by our named executive officers will become options in connection with this offering.

        Prior to 2006, certain current and former service providers were granted options to purchase Class B common stock. In connection with this offering, holders of vested options were offered the opportunity to amend these options so that they become options to purchase our Class A common stock governed by our 2020 Plan. The amended options will cover the same number of shares as the existing options and will have the same exercise price per share as the existing options, subject to the

109


Table of Contents

3-for-1 forward stock split that will occur in connection with this offering. Mr. DeStefano is our only named executive officer that holds a vested option to purchase Class B common stock and we expect that this option will be amended in connection with this offering.

        Shares issued to Mr. DeStefano upon the exercise of options to purchase Class A common stock may be sold by him in the event the underwriters exercise their option to purchase additional shares in this offering. For additional information, including the maximum number of shares that may be sold by Mr. DeStefano if the underwriters exercise the over-allotment option in full, see the sections titled "Principal and Selling Stockholders" and "Underwriting."

        Future Equity Compensation Programs.    We adopted the 2020 Plan in order to facilitate the grant of cash and equity incentives to directors, employees (including our named executive officers) and consultants of the company and certain of its affiliates and to enable the company and certain of its affiliates to obtain and retain services of these individuals, which we believe is essential to our long-term success. The 2020 Plan will be effective on the effective date of the registration statement of which this prospectus forms a part. For additional information about the 2020 Plan, please see the section titled "Incentive Compensation Plans" below.

Other Elements of Compensation

Retirement Plans

        We currently maintain a 401(k) retirement savings plan for our employees, including our named executive officers, who satisfy certain eligibility requirements. Our named executive officers are eligible to participate in the 401(k) plan on the same terms as other full-time employees. The Internal Revenue Code allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) plan. Currently, we match 50% of contributions made by participants in the 401(k) plan up to 6% of a participant's eligible compensation. During 2019, we also made discretionary profit sharing contributions under the 401(k) plan. These matching and profit sharing contributions are subject to vesting at the rate of 20% each year over the first five years of employment. We believe that providing a vehicle for tax-deferred retirement savings though our 401(k) plan, and making matching contributions, adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our named executive officers, in accordance with our compensation policies.

Health/Welfare Plans

        All of our full-time employees, including our named executive officers, are eligible to participate in our health and welfare plans, including, medical and dental benefits; medical and dependent care flexible spending accounts; short-term and long-term disability insurance; and life insurance.

Perquisites and Other Personal Benefits

        We provide our named executive officers with perquisites that we believe to be necessary and appropriate to provide a competitive compensation package, certain of which are described below. The actual amount of all perquisites and other personal benefits provided to our named executive officers during 2019 are set forth above in the Summary Compensation Table in the column entitled "All Other Compensation."

        Supplemental Executive Benefits.    During 2019, our named executive officers were eligible for certain benefits in addition to the standard employee benefits offered to all employees generally, including, (i) supplemental term life insurance in a face amount of $750,000, subject to certain conditions regarding insurability; and (ii) supplemental disability pay and insurance, which when combined with the disability coverage provided under our long-term disability insurance plan, provided the named executive officer with disability income equal to 80% of the named executive officer's

110


Table of Contents

pre-disability base salary. The named executive officers were reimbursed for the premiums paid for such supplemental life and disability insurance, including an associated tax gross-up. The named executive officers will no longer be entitled to these supplemental executive benefits following this offering. See "Recent Changes in Executive Compensation—Executive Employment Agreements" for additional information.

        Supplemental Perquisites.    Prior to this offering, we provided Ms. Butler and Mr. Rowland with an annual reimbursement of $3,300 (which represents an allowance of $2,000 plus an approximate gross up for income taxes) for the purchase of additional perquisites, including, health club membership, personal financial planning/investment advice, estate planning, certain legal advice, personal physical examination, a home office and vacation travel. Any amounts not used in one year could be "rolled-over" to the next year, but the executives could not receive reimbursement of more than $16,500 for such perquisites in any five-year period.

        Pursuant to the terms of his employment agreement, Mr. DeStefano was entitled to reimbursement of up $15,000 per year (plus a tax gross-up on any such reimbursement) for certain expenses related to financial and estate planning services, legal advice related to employment with the company, investment advice, health club memberships, physical examinations, a home office and vacation travel. Additionally, we pay approximately $10,000 per year for Mr. DeStefano's membership in the Union League Club, which he primarily uses for business purposes.

        The named executive officers will no longer be entitled to certain of these annual expense reimbursements following this offering. See "Recent Changes in Executive Compensation—Executive Employment Agreements" for additional information.

        Ms. Butler is entitled to reimbursement of up to $75,000 (plus a tax gross-up on any such reimbursement) for tuition and tuition-related expenses incurred in connection with her pursuing a master's degree in business administration; provided that, Ms. Butler must repay any such reimbursements in the event she terminates her employment within one year of completing the degree. No amounts have been paid pursuant to this arrangement as of the date of this prospectus.

        Strategic Bonus.    Pursuant to her employment agreement, Ms. Butler is entitled to a $75,000 cash bonus payment upon the first to occur of (i) filing of the company's first Form 10-Q during 2020; (ii) the date the board of directors determines to terminate pursuit of filing a Form S-1 during 2020; and (iii) December 31, 2020. Additionally, if within 6 months of the occurrence of any of the foregoing, the company and Ms. Butler agree to terminate her employment agreement, Ms. Butler would be entitled to the severance payments and benefits provided under her employment agreement.

Executive Compensation Arrangements

        We have entered into employment agreements with each of our named executive officers that sets forth the terms and conditions of each executive's employment with us. In addition, we entered into an employment agreement with John Schwab, our Chief Financial Officer, in connection with his commencement of employment with us in January 2020.

        In connection with this offering, we entered into new employment agreements with Mr. DeStefano, Ms. Butler, Mr. Rowland and Mr. Schwab. See "Recent Changes in Executive Compensation—Executive Employment Agreements" below for additional information.

Salary; Bonus

        The employment agreements entitle the executives to annual base salaries and eligibility to earn discretionary bonuses under our annual and long-term cash bonus plans. See "2019 Salaries" and "Cash-Based Incentive Compensation" above for additional information regarding the base salaries and bonus opportunities of our named executive officers for 2019.

        Mr. Schwab's employment agreement entitles him to an annual base salary of $420,000 and provides for an annual bonus target under the Organizational Bonus Plan of 60% of his base salary and a bonus target under the Company's Long-Term Rewards Plan of 50% of his base salary. Pursuant to his employment agreement, Mr. Schwab received a one-time bonus of $240,000 and was granted 496,473 stock appreciation rights in connection with his commencement of employment. The sign-on bonus is subject to full or partial repayment in the event Mr. Schwab voluntarily resigns or is

112


Table of Contents

terminated for cause within the first 18 months of employment. The stock appreciation rights vest pursuant to our standard vesting schedule described above. In addition, Mr. Schwab may be entitled to additional cash bonuses of up to $420,000 and stock appreciation rights equivalent to 5% of the company's Class B common stock if this offering does not occur by April 1, 2022.

Term

        The initial term of Mr. DeStefano's employment agreement expired in November 2019 and automatically renews for successive two year periods unless 60 days' prior notice of non-renewal is given by either party. The employment agreements for Ms. Butler, Mr. Rowland and Mr. Schwab are for indefinite terms.

Severance

        If we terminate Mr. DeStefano, Ms. Butler, Mr. Rowland or Mr. Schwab without cause, or with respect to Mr. Rowland and Mr. Schwab only, the executive resigns for good reason, subject to the executive timely executing a release of claims, the executive is entitled to receive (i) base salary continuation for 12 months (or 24 months for Mr. DeStefano); and (ii) direct payment of, or additional cash payments equal to, the premiums for continued health coverage for up to 18 months. Mr. DeStefano is also entitled to an additional lump sum payment equal to 12 months of health coverage premiums in the event he has not become eligible for health insurance coverage from a subsequent employer by the date that is 15 months following such termination of employment.

        Notwithstanding the foregoing, any continued base salary payments for Mr. DeStefano, Mr. Rowland and Mr. Schwab will be reduced by any salary or bonus paid to the executive by a subsequent employer during the applicable severance period.

        The receipt of severance payments and benefits for Mr. DeStefano, Mr. Rowland and Mr. Schwab is also subject to the executive's continued compliance with certain restrictive covenants and confidentiality obligations as described below under "Restrictive Covenants." In the event of a material breach of such covenants by Mr. DeStefano, Mr. Rowland or Mr. Schwab, subject to certain cure rights, the executive's right to receive any of the severance payments or benefits described above will cease and the executive will be obligated to repay to the company any such payments or benefits previously paid.

        Each of Mr. DeStefano, Ms. Butler, Mr. Rowland and Mr. Schwab is entitled to 30 days' notice, or pay in lieu of notice, in the event we terminate the executive for any reason other than cause.

        For purposes of the employment agreements, "cause" generally means, subject to certain notice and cure rights, the executive's (i) material breach of the employment agreement; (ii) repeated failure to perform duties to the company or any subsidiary; (iii) willful misconduct that is materially injurious to the company or any subsidiary (or for Mr. Rowland and Mr. Schwab, willful misconduct or gross negligence with regard to the company, any subsidiary or their business, assets or employees); (iv) dishonesty, unethical, fraudulent or similar misconduct in connection with the executive's employment or service; (v) use of non-prescription controlled substances, misuse of prescription drugs, or habitual intoxication during work hours; (vi) other than for Ms. Butler, indictment for any felony that has or is reasonably likely to cause material adverse consequences to the company, its businesses or prospects; (vii) conviction, guilty plea or plea of nolo contendere to a felony or any crime involving fraud, dishonesty or moral turpitude; (viii) material violation of any company policy; (ix) refusal to follow any reasonable and lawful direction of the board of directors or any person to whom the executive reports, if applicable; or (x) for Mr. Rowland only, breach of a fiduciary duty owed to the company in good faith.

Director Compensation

        The non-employee members of our board of directors are eligible to receive compensation for their service on our board of directors. The 2019 compensation for the non-employee members of our board of directors consisted of (i) an annual director fee of $112,910 (or $80,000 for directors who commenced service on the board of directors in 2018 or 2019); (ii) additional annual fees for committee service of $6,300 for service on a board committee (other than the chair) or $12,600 for service as chair of a board committee; and (iii) consulting fees in the amount of $500 per hour for additional board services beyond the scope of a director's customary service as a member of the board of directors. In addition, during 2019 the non-employee directors were eligible to receive a discretionary annual bonus targeted at $120,000 and payable as to seventy-five percent (75%) in cash and twenty-five percent (25%) in stock appreciation rights. The amount of the annual bonus was determined based on the company's performance against the financial and non-financial goals under the Organizational Bonus Plan for the given year, although the company's stockholders retained discretion to increase or decrease the actual bonuses awarded to the directors. The stockholders did not exercise this discretion with respect to the 2019 bonuses and the actual annual bonuses awarded to each non-employee director for 2019 are set forth in the Director Compensation Table below in the column entitled "Non-Equity Incentive Plan Compensation." See the section of this prospectus titled "—Cash-Based Incentive Compensation" above for a description of company performance under the Organization Bonus Plan for 2019.

Non-Employee Director Compensation Program

        In connection with this offering, our board of directors adopted and stockholders approved a new compensation program for our non-employee directors. Under this program our non-employee directors receive the following amounts for their services on our board of directors:

        Director fees under the program will be earned and paid monthly. Restricted stock units represent the right to receive one share (or an equal amount in cash) following vesting of the award as described in further detail below in the section entitled "Incentive Compensation Plans—2020 Incentive Award Plan—Awards—Restricted Stock and RSUs." Restricted stock units granted to our non-employee directors under the program will vest in a single installment on the earlier of the day before the next annual meeting of stockholders occurring after the date of grant or the first anniversary of the date of grant, subject to continued service as a non-employee member of our board through the applicable vesting date and accelerated vesting upon a change in control of the company.

IPO Grants to Non-Employee Directors

        In connection with this offering, we intend to grant our non-employee directors awards of restricted stock under the 2020 Plan in the amounts set forth in the table below under the heading "Value of Annual Award for 2020" as part of their annual compensation for service on the board during 2020. In addition, in recognition of their significant contributions to the Company in connection with this offering, Mr. Andersen, Mr. Kyle and Mr. Stamm will be granted one-time awards in the amounts set forth in the table below under the heading "Value of One-Time IPO Award". The number of shares subject to each award will be determined by dividing the amounts shown in the table below for such director by the initial public offering price per share of the Class A common stock in this offering, with any partial shares that result being rounded up to the nearest whole share. The shares of restricted stock will vest on the earlier of the day before the next annual meeting of the Company's stockholders occurring after the date of grant or the first anniversary of the date of grant, subject to

        The following summarizes the material terms of the 2020 Plan and the 2020 Employee Stock Purchase Plan, which will be the long-term incentive compensation plans in which our directors and named executive officers will be eligible to participate following the consummation of this offering, subject to the terms and conditions of such plans, and the Third Amended and Restated 2007 Stock Appreciation Rights Plan, under which we have previously made periodic grants of stock appreciation rights to our directors and named executive officers.

2020 Incentive Award Plan

        Effective on the effective date of the registration statement of which this prospectus forms a part, we adopted and our stockholders approved the 2020 Plan under which we may grant cash and equity-based incentive awards to eligible service providers in order to attract, retain and motivate the persons who make important contributions to the company. The material terms of the 2020 Plan are summarized below.

        Eligibility and Administration.    Our employees, consultants and directors, and employees and consultants of our subsidiaries will be eligible to receive awards under the 2020 Plan. The 2020 Plan will be administered by our board of directors with respect to awards to non-employee directors and by our compensation committee with respect to other participants, each of which may delegate its duties and responsibilities to committees of our directors and/or officers (referred to collectively as the plan administrator below), subject to the limitations that may be imposed under the 2020 Plan, Section 16 of the Exchange Act, stock exchange rules and other applicable laws. The plan administrator will have the authority to take all actions and make all determinations under the 2020 Plan, to interpret the 2020 Plan and award agreements and to adopt, amend and repeal rules for the administration of the 2020 Plan as it deems advisable. The plan administrator will also have the authority to determine which eligible service providers receive awards, grant awards and set the terms and conditions of all awards under the 2020 Plan, including any vesting and vesting acceleration provisions, subject to the conditions and limitations in the 2020 Plan.

        Shares Available.    An aggregate of 16,500,000 shares of our Class A common stock will initially be available for issuance under the 2020 Plan. The number of shares initially available for issuance will be increased by an annual increase on January 1 of each calendar year beginning in 2021 and ending in and including 2030, equal to the lesser of (A) 4% of the shares of Class A and Class B common stock outstanding on the final day of the immediately preceding calendar year and (B) a smaller number of shares as determined by our board of directors. No more than 3,000,000 shares of Class A common stock may be issued under the 2020 Plan upon the exercise of incentive stock options. Shares available under the 2020 Plan may be authorized but unissued shares, shares purchased on the open market or treasury shares.

Table of Contents

        If an award under the 2020 Plan expires, lapses or is terminated, exchanged for cash, surrendered, repurchased, or canceled without having been fully exercised or forfeited, any unused shares subject to the award will again be available for new grants under the 2020 Plan. Awards granted under the 2020 Plan in substitution for any options or other stock or stock-based awards granted by an entity before the entity's merger or consolidation with us or our acquisition of the entity's property or stock will not reduce the shares available for grant under the 2020 Plan, but will count against the maximum number of shares that may be issued upon the exercise of incentive stock options.

        Awards.    The 2020 Plan provides for the grant of stock options, including incentive stock options ("ISOs") and nonqualified stock options ("NSOs"), SARs, restricted stock, dividend equivalents, RSUs, and other stock or cash based awards. Certain awards under the 2020 Plan may constitute or provide for payment of "nonqualified deferred compensation" under Section 409A of the Code. All awards under the 2020 Plan will be set forth in award agreements, which will detail the terms and conditions of awards, including any applicable vesting and payment terms and post-termination exercise limitations. A brief description of each award type follows.

Table of Contents

        Performance Criteria.    The plan administrator may select performance criteria for an award to establish performance goals for a performance period. Performance criteria under the 2020 Plan may include, but are not limited to, the following: net earnings or losses (either before or after one or more of interest, taxes, depreciation, amortization, and non-cash equity-based compensation expense); gross or net sales or revenue or sales or revenue growth; net income (either before or after taxes) or adjusted net income; profits (including but not limited to gross profits, net profits, profit growth, net operation profit or economic profit), profit return ratios or operating margin; budget or operating earnings (either before or after taxes or before or after allocation of corporate overhead and bonus); cash flow (including operating cash flow and free cash flow or cash flow return on capital); return on assets; return on capital or invested capital; cost of capital; return on stockholders' equity; total stockholder return; return on sales; costs, reductions in costs and cost control measures; expenses; working capital; earnings or loss per share; adjusted earnings or loss per share; price per share or dividends per share (or appreciation in or maintenance of such price or dividends); regulatory achievements or compliance; implementation, completion or attainment of objectives relating to research, development, regulatory, commercial, or strategic milestones or developments; market share; economic value or economic value added models; division, group or corporate financial goals; customer satisfaction/growth; customer service; employee satisfaction; recruitment and maintenance of personnel; human resources management; supervision of litigation and other legal matters; strategic partnerships and transactions; financial ratios (including those measuring liquidity, activity, profitability or leverage); debt levels or reductions; sales-related goals; financing and other capital raising transactions; cash on hand; acquisition activity; investment sourcing activity; and marketing initiatives, any of which may be measured in absolute terms or as compared to any incremental increase or decrease. Such performance goals also may be based solely by reference to the company's performance or the performance of a subsidiary, division, business segment or business unit of the company or a subsidiary, or based upon performance relative to performance of other companies or upon comparisons of any of the indicators of performance relative to performance of other companies. When determining performance goals, the plan administrator may provide for exclusion of the impact of an event or occurrence which the plan administrator determines should appropriately be excluded, including, without limitation, non-recurring charges or events, acquisitions or divestitures, changes in the corporate or capital structure, events unrelated to the business or outside of the control of management, foreign exchange considerations, and legal, regulatory, tax or accounting changes.

        Certain Transactions.    In connection with certain corporate transactions and events affecting our Class A common stock, including a change in control, or change in any applicable laws or accounting principles, the plan administrator has broad discretion to take action under the 2020 Plan to prevent the dilution or enlargement of intended benefits, facilitate the transaction or event or give effect to the change in applicable laws or accounting principles. This includes canceling awards for cash or property, accelerating the vesting of awards, providing for the assumption or substitution of awards by a successor entity, adjusting the number and type of shares subject to outstanding awards and/or with respect to which awards may be granted under the 2020 Plan and replacing or terminating awards under the 2020 Plan. In addition, in the event of certain non-reciprocal transactions with our stockholders, the plan administrator will make equitable adjustments to the 2020 Plan and outstanding awards as it deems appropriate to reflect the transaction. In the event of a change in control of the company (as defined in the 2020 Plan), to the extent that the surviving entity declines to continue, convert, assume or replace outstanding awards, then all such awards may become fully vested and exercisable in connection with the transaction. Individual award agreements may provide for additional accelerated vesting and payment provisions.

        Provisions of the 2020 Plan Relating to Director Compensation.    The 2020 Plan provides that the plan administrator may establish compensation for non-employee directors from time to time subject to the 2020 Plan's limitations. In connection with this offering, our board of directors adopted and stockholders approved a compensation program for our non-employee directors. Our board of directors

120


Table of Contents

or its authorized committee may modify the non-employee director compensation program from time to time in the exercise of its business judgment, taking into account such factors, circumstances and considerations as it shall deem relevant from time to time, provided that the sum of any cash compensation or other compensation and the grant date fair value of any equity awards granted under the 2020 Plan as compensation for services as a non-employee director during any fiscal year may not exceed $750,000, excluding cash and other compensation awarded prior to the effective date of the 2020 Plan, compensation awarded in connection with this offering and compensation granted to a non-employee director who serves in a capacity in addition to that of non-employee director for which he or she receives additional compensation. The plan administrator may make exceptions to this limit for individual non-employee directors in extraordinary circumstances, as the plan administrator may determine in its discretion, subject to the limitations in the 2020 Plan.

        Foreign Participants, Claw-Back Provisions, Transferability, and Participant Payments.    The plan administrator may modify awards granted to participants who are foreign nationals or employed outside the United States or establish subplans or procedures to address differences in laws, rules, regulations or customs of such foreign jurisdictions. All awards will be subject to any company claw-back policy as set forth in such claw-back policy or the applicable award agreement. Except as the plan administrator may determine or provide in an award agreement, awards under the 2020 Plan are generally non-transferrable, except by will or the laws of descent and distribution, or, subject to the plan administrator's consent, pursuant to a domestic relations order and are generally exercisable only by the participant. With regard to tax withholding obligations arising in connection with awards under the 2020 Plan and exercise price obligations arising in connection with the exercise of stock options under the 2020 Plan, the plan administrator may, in its discretion, accept cash, wire transfer or check, shares of our common stock that meet specified conditions, a promissory note, a "market sell order," such other consideration as the plan administrator deems suitable or any combination of the foregoing.

        Plan Amendment and Termination.    Our board of directors may amend or terminate the 2020 Plan at any time; however, no amendment, other than an amendment that increases the number of shares available under the 2020 Plan, may materially and adversely affect an award outstanding under the 2020 Plan without the consent of the affected participant and stockholder approval will be obtained for any amendment to the extent necessary to comply with applicable laws. Further, the plan administrator may not, without the approval of our stockholders, amend any outstanding stock option or SAR to reduce its price per share, other than in the context of corporate transactions or equity restructurings, as described above. The 2020 Plan will remain in effect until the tenth anniversary of the earlier of the date the board of directors adopted the 2020 Plan and the date the Company's stockholders approved the 2020 Plan, unless earlier terminated by our board of directors. No awards may be granted under the 2020 Plan after its termination.

2020 Employee Stock Purchase Plan

        Effective on the effective date of the registration statement of which this prospectus forms a part, we adopted and our stockholders approved the 2020 Employee Stock Purchase Plan (the "2020 ESPP"), the material terms of which are summarized below.

        The 2020 ESPP is comprised of two distinct components in order to provide increased flexibility to grant options to purchase shares under the 2020 ESPP to U.S. and to non-U.S. employees. Specifically, the 2020 ESPP authorizes (1) the grant of options to U.S. employees that are intended to qualify for favorable U.S. federal tax treatment under Section 423 of the Code (the "Section 423 Component"), and (2) the grant of options that are not intended to be tax-qualified under Section 423 of the Code to facilitate participation for employees located outside of the U.S. who do not benefit from favorable U.S. federal tax treatment and to provide flexibility to comply with non-U.S. law and other considerations (the "Non-Section 423 Component"). Where permitted under local law and custom, we

121


Table of Contents

expect that the Non-Section 423 Component will generally be operated and administered on terms and conditions similar to the Section 423 Component.

        Shares Available for Awards; Administration.    A total of 1,000,000 shares of our Class A common stock will initially be reserved for issuance under the 2020 ESPP. In addition, the number of shares available for issuance under the 2020 ESPP will be annually increased on January 1 of each calendar year beginning in 2021 and ending in and including 2030, by an amount equal to the lesser of (A) 1% of the shares of Class A and Class B common stock outstanding on the final day of the immediately preceding calendar year and (B) such smaller number of shares as is determined by our board of directors, provided that no more than 16,000,000 shares of our Class A common stock may be issued under the Section 423 Component. Our board of directors or a committee of our board of directors will administer and will have authority to interpret the terms of the 2020 ESPP and determine eligibility of participants. We expect that the compensation committee will be the initial administrator of the 2020 ESPP.

        Eligibility.    We expect that all of our employees will be eligible to participate in the 2020 ESPP. However, an employee may not be granted rights to purchase stock under our 2020 ESPP if the employee, immediately after the grant, would own (directly or through attribution) stock possessing 5% or more of the total combined voting power or value of all classes of our stock.

        Grant of Rights.    Stock will be offered under the 2020 ESPP during offering periods. The length of the offering periods under the 2020 ESPP will be determined by the plan administrator and may be up to twenty-seven months long. Employee payroll deductions will be used to purchase shares on each purchase date during an offering period. The purchase dates for each offering period will be the final trading day in the offering period. Offering periods under the 2020 ESPP will commence when determined by the plan administrator. We expect the initial offering period under the 2020 ESPP to commence on the pricing date of our Class A common stock in this offering. The plan administrator may, in its discretion, modify the terms of future offering periods. In non-U.S. jurisdictions where participation in the 2020 ESPP through payroll deductions is prohibited, the plan administrator may provide that an eligible employee may elect to participate through contributions to the participant's account under the 2020 ESPP in a form acceptable to the 2020 ESPP administrator in lieu of or in addition to payroll deductions.

        The 2020 ESPP permits participants to purchase Class A common stock through payroll deductions of up to a specified percentage of their eligible compensation, provided that participants will be permitted to make lump sum contributions to the 2020 ESPP during the initial offering period. The plan administrator will establish a maximum number of shares that may be purchased by a participant during any offering period. In addition, no employee will be permitted to accrue the right to purchase stock under the Section 423 Component at a rate in excess of $25,000 worth of shares during any calendar year during which such a purchase right is outstanding (based on the fair market value per share of our Class A common stock as of the first day of the offering period).

        On the first trading day of each offering period, each participant will automatically be granted an option to purchase shares of our Class A common stock. The option will expire at the end of the applicable offering period, and will be exercised at that time to the extent of the payroll deductions (or contributions) accumulated during the offering period. The purchase price of the shares, in the absence of a contrary designation, will be 85% of the lower of the fair market value of our Class A common stock on the first trading day of the offering period (in the case of the initial offering period, the initial public offering price) or on the purchase date. Participants may voluntarily end their participation in the 2020 ESPP at any time during a specified period prior to the end of the applicable offering period, and will be paid their accrued payroll deductions (and contributions, if applicable) that have not yet been used to purchase shares of Class A common stock. If a participant withdraws from the 2020 ESPP

122


Table of Contents

during an offering period, the participant cannot rejoin until the next offering period. Participation ends automatically upon a participant's termination of employment.

        A participant may not transfer rights granted under the 2020 ESPP other than by will or the laws of descent and distribution, and are generally exercisable only by the participant.

        Certain Transactions.    In the event of certain non-reciprocal transactions or events affecting our Class A common stock, the plan administrator will make equitable adjustments to the 2020 ESPP and outstanding rights. In the event of certain unusual or non-recurring events or transactions, including a change in control, the plan administrator may provide for (1) either the replacement of outstanding rights with other rights or property or termination of outstanding rights in exchange for cash, (2) the assumption or substitution of outstanding rights by the successor or survivor corporation or parent or subsidiary thereof, if any, (3) the adjustment in the number and type of shares of stock subject to outstanding rights, (4) the use of participants' accumulated payroll deductions to purchase stock on a new purchase date prior to the next scheduled purchase date and termination of any rights under ongoing offering periods or (5) the termination of all outstanding rights.

        Plan Amendment.    The plan administrator may amend, suspend or terminate the 2020 ESPP at any time. However, stockholder approval will be obtained for any amendment that increases the aggregate number or changes the type of shares that may be sold pursuant to rights under the 2020 ESPP or changes the corporations or classes of corporations whose employees are eligible to participate in the 2020 ESPP.

2007 Stock Appreciation Rights Plan

        Our board of directors has approved our Third Amended and Restated 2007 Stock Appreciation Rights Plan (the "2007 Plan"), under which we have granted SARs to employees of the company or its subsidiaries and our directors.

        In connection with this offering, holders of outstanding SARs were offered the opportunity to amend outstanding SARs, whether vested or unvested, so that, upon effectiveness of the 2020 Plan, they become options to purchase shares of our Class A common stock under the 2020 Plan. These options will cover an equal number of shares as the amended SARs and have an exercise price per share equal to the base price of an amended SAR, subject to the 3-for-1 forward stock split that was effective on July 28, 2020. Options resulting from the amendment of SARs that do not have an expiration date or SARs that expire during calendar year 2020 will automatically be exercised in connection with this offering for shares of our Class A common stock (the "Auto Exercise New Options"). Shares issued in connection with the Auto Exercise New Options will be net of the number of shares of common stock necessary to satisfy the aggregate exercise price and the tax withholding obligation of such options. The Auto Exercise New Option participants also had the ability to require us to repurchase all or a portion of the shares remaining on the offering date after this reduction for cash based on the offering price. As of June 30, 2020, and giving effect to the 3-for-1 forward stock split effective on July 28, 2020, there were 1,900,419 SARs outstanding with no expiration date or that expire during calendar year 2020. Of these, we expect that 1,338,220 shares will be sold to us in connection with this offering. For the period from April 1, 2020 through the date of this prospectus, the Company will have additional compensation expense of $19.7 million related to the Auto Exercise New Options (at a fair value of $19.00 per share), and also expects to use approximately $22.9 million of the proceeds from this offering to pay tax withholding of approximately $13.8 million and to repurchase the shares sold by Auto Exercise New Option participants to the Company for approximately $9.1 million. The recognition of stock-based compensation would affect our cost of revenue and our research and development, sales and marketing, and general and administrative operating expense line items. Options resulting from the amendment of SARs that have an expiration date after calendar year 2020 will not be automatically exercised in connection with this offering. Such

123


Table of Contents

options will be governed by the 2020 Plan and the applicable award agreement and, to the extent unvested, will vest pursuant to the same vesting schedule that applied to the amended SARs.

        Our board of directors, or a committee of the board, administers the 2007 Plan. Subject to the express terms and conditions of the 2007 Plan, the plan administrator has the authority to make all determinations and interpretations under the 2007 Plan and determine the terms and conditions of all awards under the 2007 Plan.

        In the event of the issuance of additional shares by the company, which has the effect of diluting the value of the common stock, the plan administrator has broad discretion to adjust the terms and conditions of existing awards under the 2007 Plan as it deems appropriate and equitable to ameliorate the effect of such dilution. Additionally, the plan administrator may make adjustments to existing awards in recognition of unusual or non-recurring events affecting the company or any subsidiary to prevent dilution or enlargement of the rights of participants under the 2007 Plan.

        Following the consummation of this offering, we will not make any further grants under the 2007 Plan, no SARs will remain outstanding under the 2007 Plan and the board of directors may terminate the 2007 Plan at any time.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Stockholders' Agreement

        Upon the completion of this offering, our principal stockholders, Amanda Westphal Radcliffe, Stefanie Westphal Thompson and Jeffrey Westphal, each of whom serves as a member of our board of directors, together with their affiliated trust entities and family members, intend to enter into an Amended and Restated Stockholders' Agreement (the "Stockholders' Agreement") with these terms:

Transfer Restrictions

        The parties to the Stockholders' Agreement will not transfer shares of our Class B common stock except: (i) to another holder of our Class B common stock; (ii) to Amanda Westphal Radcliffe, Stefanie Westphal Thompson or Jeffrey Westphal or their family members or affiliates, as described in the Stockholders' Agreement; (iii) to the Company; (iv) or in an underwritten public offering or other transaction approved by a majority of the disinterested members of our board of directors or a committee of our board of directors authorized to take such action ("Permitted Transfers"). Each party to whom Class B common stock is transferred will be required to become a party to the Stockholders' Agreement, if they are not a party already. Each share of our Class B common stock will convert automatically into one share of our Class A common stock upon any transfer, whether or not for value, except for certain permitted transfers described in our amended and restated certificate of incorporation, including transfers to Amanda Westphal Radcliffe, Stefanie Westphal Thompson and Jeffrey Westphal or their family members or affiliates.

Right of First Offer / Refusal

        Before transferring any shares of our Class B common stock, other than through a Permitted Transfer, the party transferring the shares must offer them, first, to the other stockholder parties and, next, to the Company. If neither of those offers is accepted, the selling stockholder may then transfer the shares to someone else. If any party receives an offer from someone who is not a party to the Stockholders' Agreement to purchase some or all of their Class B common stock, that person must give the other parties notice of the offer and an opportunity to purchase the shares on the same terms.

Subscription Rights

        The parties to the Stockholders' Agreement will have the right, but not the obligation, to purchase a number of shares of Class A common stock up to their proportionate interest of any new shares of Class A common stock, or any securities convertible into, exercisable for, or exchangeable for Class A common stock issued in a private offering, other than securities (including either shares of Class A common stock or Class B common stock) issued to any director, employee or consultant of the Company or any of its subsidiaries pursuant to an equity-incentive plan approved by the Board or in connection with stock splits, stock dividends, in-kind equity distributions, recapitalizations and stockholders' rights plans, or a greater amount if any of the other parties to the Stockholders' Agreement do not elect to purchase their proportionate share of the newly issued securities.

Registration Rights

        After our initial public offering and the expiration of any related lock-up period, any stockholder party to the Stockholders' Agreement can require us to register under the Securities Act shares of our common stock held by them if the anticipated aggregated offering amount exceeds $50.0 million subject to certain limitations. They will also have shelf registration rights requiring us, when we are eligible for short-form registration, to file a shelf registration statement and to keep it effective to allow sales from time to time. They will also be entitled to participate as selling stockholders on a pro rata basis in any registration of our common stock under the Securities Act that we may undertake. We will pay expenses relating to these registrations and will indemnify the parties participating in these offerings against liabilities that may arise from the offering process.

125


Table of Contents

Standstill

        For so long as any stockholder party to the Stockholders' Agreement owns any shares of Class B common stock, the party will not engage or participate in: (i) acquiring the Company's securities (other than through market-based purchases of up to 2% of outstanding equity in any 12-month period, the exercise or conversion of outstanding securities or equity awards); (ii) any tender or exchange offer, merger or other business combination involving the Company, any of our subsidiaries or affiliates or our assets constituting a significant portion of the consolidated assets of the Company and its subsidiaries or affiliates; (iii) any recapitalization, restructuring, liquidation, dilution or other extraordinary transaction involving the Company; or (iv) the solicitation of any proxies or written consents involving the Company. The parties must promptly inform the board of directors about any approaches by a third party regarding any of these matters. The board of directors and holders of a majority of the Class B common stock may agree to waive the standstill prohibition.

Director Designation Rights

        For so long as Amanda Westphal Radcliffe, Stefanie Westphal Thompson or Jeffrey Westphal, in each case together with his or her children and related trusts, owns at least five percent of our outstanding common stock, he or she each shall be entitled to designate one individual, including themselves, to serve as a member of our board of directors, and we will be required to use our best efforts to include the designee in the slate of nominees recommended to our stockholders for election as a director at the next annual or special meeting of stockholders.

Director Voting

        At any general or special meeting of the stockholders involving the election of directors, each stockholder party to the Stockholders' Agreement must vote all of his or her shares of stock in favor of each individual nominated by the parties to the Stockholders' Agreement. For all matters other than the election of directors, voting shall be discretionary at the option of each stockholder.

Tax Sharing Agreement

        Prior to this offering, we have elected to be treated as an S Corporation for U.S. federal income tax purposes, as a result of which our existing stockholders have been required to pay income taxes attributable to our earnings. We have historically paid distributions to our existing stockholders, which have assisted them in paying such income taxes. As of July 27, 2020, our S Corporation status will terminate and we will thereafter be subject to federal and increased U.S. state income taxes. Our existing stockholders may be required to pay additional income taxes for periods prior to the termination of our S Corporation status as a result of an adjustment to our taxable income for periods beginning after our S Corporation status terminates. Accordingly, we entered into an agreement with our existing stockholders in connection with this offering. Under this agreement, we may be required to make payments in material amounts to our existing stockholders with respect to any incremental income taxes resulting from an adjustment to our taxable income for any period beginning after our S Corporation status terminates. Furthermore, this agreement requires us to indemnify our existing stockholders with respect to unpaid income tax liabilities attributable to our taxable income for any period after the termination of our S Corporation status. We will also indemnify our existing stockholders for any interest, penalties, losses, costs or expenses arising out of any claim under the agreement. However, our existing stockholders will indemnify us with respect to our unpaid tax liabilities (including interest and penalties) to the extent that such unpaid tax liabilities are attributable to a decrease in our existing stockholders' taxable income for any period and a corresponding increase in our taxable income for any period.

Indemnification Agreements

        Our amended and restated certificate of incorporation will provide that we will indemnify our directors and officers to the fullest extent permitted by law. In addition, we expect to enter into

126


Table of Contents

indemnification agreements with all of our directors and executive officers prior to the completion of this offering. See "Description of Capital Stock—Limitation on Liability of Directors and Indemnification."

Compensation Arrangements

        For a description of the compensation arrangements we have with our executive officers, see "Executive Compensation."

        In connection with their service as employees of the Company, each of Stefanie Westphal Thompson, Amanda Westphal Radcliffe and Jeffrey Westphal received annual salaries of $120,191 in 2019, 2018 and 2017 and were also entitled to participate in the Company's standard health, insurance and retirement benefits plans. Effective June 1, 2020, Ms. Radcliffe, Ms. Thompson and Mr. Westphal no longer serve as our employee.

Distributions

        During the years ended December 31, 2019, December 31, 2018 and December 31, 2017, we paid distributions of $28.6 million, $28.0 million and $17.6 million, respectively, to our stockholders.

Class B Share Purchase

        Jeffrey Westphal, Amanda Westphal Radcliffe, Stefanie Westphal Thompson and Vertex have agreed that Amanda Westphal Radcliffe and Stefanie Westphal Thompson will immediately before this offering purchase from Jeffrey Westphal shares of his Class B common stock equal to a total of $30.0 million, at the public offering price per share, net of underwriting discounts and commissions.

Directed Share Program

        At our request, the underwriters have reserved for sale, at the initial public offering price, up to 5% of the Class A common stock offered by this prospectus for sale to some of our directors, officers, employees, business associates and related persons. We do not currently know the extent to which these related persons will participate in our directed share program, if at all.

Our Policy Regarding Related Party Transactions

        Upon consummation of this offering, our board of directors will have adopted written policies and procedures for transactions with related persons. As a general matter, the policy will require the audit committee to review and approve or disapprove of the entry by us into certain transactions with related persons. The policy will only apply to transactions, arrangements and relationships where the aggregate amount involved could reasonably be expected to exceed $120,000 in any calendar year and in which a related person has a direct or indirect interest. A related person is: (a) any director, nominee for director or executive officer of our company; (b) any immediate family member of a director, nominee for director or executive officer; and (c) any person, and his or her immediate family members, or entity, including affiliates, that was a beneficial owner of 5% or more of any of our outstanding equity securities at the time the transaction occurred or existed.

        The policy will provide that if advance approval of a transaction subject to the policy is not obtained, it must be promptly submitted to the committee for possible ratification, approval, amendment, termination or rescission. In reviewing any transaction, the committee will take into account, among other factors the committee deems appropriate, recommendations from senior management, whether the transaction is on terms no less favorable than terms generally available to a third party in similar circumstances and the extent of the related person's interest in the transaction. Any related person transaction must be conducted at arm's length. Any member of the audit committee who is a related person with respect to a transaction under review may not participate in the deliberations or vote on the approval or ratification of the transaction. However, such a director may be counted in determining the presence of a quorum at a meeting of the audit committee that considers the transaction.

Table of Contents


PRINCIPAL AND SELLING STOCKHOLDERS

        The following table sets forth information with respect to the beneficial ownership of our common stock as of June 30, 2020, both before and after giving effect to the closing of the offering, by:

        The amounts and percentages of our Class A and Class B common stock beneficially owned are reported on the basis of SEC regulations governing the determination of beneficial ownership of securities. Under SEC rules, a person is deemed to be a "beneficial" owner of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are not deemed to be outstanding for purposes of computing any other person's percentage. Under these rules, more than one person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

        Our determination of the percentage of beneficial ownership prior to this offering gives effect to the reclassification and the 3-for-1 forward split of our common stock and is based on 1,426,819 shares of our Class A common stock and 120,417,000 shares of our Class B common stock outstanding as of June 30, 2020. Our determination of beneficial ownership after this offering is based on 25,749,319 shares of our Class A common stock and 120,417,000 shares of our Class B common stock outstanding after closing of the offering and assumes the underwriters exercise their option to purchase up to 3,172,500 shares of Class A common stock from the selling stockholders.

DESCRIPTION OF CAPITAL STOCK

General

        As of the closing of this offering, after giving effect to the reclassification, our authorized capital stock will consist of 450,000,000 shares of common stock, par value $0.001 per share, and 30,000,000 shares of preferred stock, par value $0.001 per share. Our common stock will be divided into two classes, Class A common stock and Class B common stock. Following this offering, our authorized Class A common stock will consist of 300,000,000 shares and our authorized Class B common stock will consist of 150,000,000 shares.

        We are selling 21,150,000 shares of Class A common stock in this offering (23,812,216 shares if the underwriters exercise their over-allotment option in full). All shares of our Class A common stock outstanding upon consummation of this offering will be fully paid and non-assessable.

        After giving affect to the reclassification and the issuance of shares of Class A common stock in connection with the amendment of outstanding SARs and as restricted stock awards, as of June 30, 2020, there were 1,426,819 shares of our Class A common stock outstanding, held by 1,112 stockholders of record, 120,417,000 shares of our Class B common stock outstanding held by 20 stockholders of record and no shares of our preferred stock outstanding.

        We expect to adopt an amended and restated certificate of incorporation and amended and restated bylaws in connection with the completion of this offering. The following description of our capital stock and provisions of our amended and restated certificate of incorporation and amended and restated bylaws are summaries and are qualified by reference to the amended and restated certificate of incorporation and amended and restated bylaws that will become effective prior to the pricing of this offering. Copies of these documents will be filed with the SEC as exhibits to our registration statement, of which this prospectus forms a part. The description of our capital stock reflects changes to our capital structure that will occur upon the closing of this offering.

Common Stock

        We have two classes of authorized common stock: Class A common stock and Class B common stock. The rights of the holders of Class A common stock and Class B common stock are identical, except with respect to voting, conversion and transfer rights.

Voting Rights

        Holders of shares of our Class A common stock are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders. Holders of shares of our Class B common stock are entitled to ten votes for each share held of record on all matters submitted to a vote of stockholders. The holders of our common stock do not have cumulative voting rights in the election of directors.

        Our amended and restated certificate of incorporation will provide that so long as any shares of Class B common stock remain outstanding, the Company shall not, without the prior affirmative vote of the holders of a majority of the outstanding shares of Class B common stock, voting as a separate class, in addition to any other vote required by applicable law or our amended and restated certificate of incorporation, whether by amendment, or through merger, consolidation or otherwise, amend, alter, change, repeal or adopt any provision of our amended and restated certificate of incorporation inconsistent with, or otherwise alter or change, any of the voting, conversion, dividend or liquidation provision of the shares of Class B common stock or other rights, powers, preferences or privileges of the shares of Class B common stock.

130


Table of Contents

        Our amended and restated certificate of incorporation will also require, so long as any shares of Class B common stock remain outstanding, the prior approval of a majority of the outstanding shares of Class B common stock for any change of control transaction.

        In addition, Delaware law would require either holders of our Class A common stock or our Class B common stock to vote separately as a class in the following circumstances:

Economic Rights

        Except as otherwise expressly provided in our amended and restated certificate of incorporation or required by applicable law, shares of Class A common stock and Class B common stock will have the same rights and privileges and rank equally, share ratably and be identical in all respects as to all matters, including, without limitation, those described below.

        Dividends.    Any dividend or distributions paid or payable to the holders of shares of Class A common stock and Class B common stock shall be paid pro rata, on an equal priority, pari passu basis, unless different treatment of the shares of each such class is approved by the affirmative vote of the holders of a majority of the outstanding shares of Class A common stock and Class B common stock, each voting separately as a class; provided, however, that if a dividend or distribution is paid in the form of Class A common stock or Class B common stock (or rights to acquire shares of Class A common stock or Class B common stock), then the holders of the Class A common stock shall receive Class A common stock (or rights to acquire shares of Class A common stock) and holders of Class B common stock shall receive Class B common stock (or rights to acquire shares of Class B common stock).

        Liquidation.    In the event of our liquidation, dissolution or winding-up, upon the completion of the distributions required with respect to any series of preferred stock that may then be outstanding, our remaining assets legally available for distribution to stockholders shall be distributed on an equal priority, pro rata basis to the holders of Class A common stock and Class B common stock unless disparate treatment is approved by the affirmative move of the holders of a majority of the outstanding shares of Class A common stock and Class B common stock, each voting separately as a class.

        Subdivisions and Combinations.    If we subdivide or combine in any manner outstanding shares of Class A common stock or Class B common stock, then the outstanding shares of the other class will be subdivided or combined in the same proportion and manner, unless different treatment of the shares of each class is approved by the affirmative vote of the holders of a majority of the outstanding shares of Class A common stock and by the affirmative vote of the holders of a majority of the outstanding shares of Class B common stock, each voting separately as a class.

No Preemptive or Similar Rights

        Holders of shares of our common stock do not have preemptive, subscription or redemption rights, except as otherwise provided in the Stockholders' Agreement. There will be no redemption or sinking fund provisions applicable to our common stock.

131


Table of Contents

Conversion

        Each outstanding share of our Class B common stock is convertible at any time at the option of the holder into one share of our Class A common stock. Each share of our Class B common stock will convert automatically into one share of our Class A common stock upon any transfer, whether or not for value, except for certain permitted transfers described in our amended and restated certificate of incorporation, including transfers to other Class B stockholders, members of our founder's family, trusts and foundations primarily for the benefit of members of our founder's family, and partnerships, corporations, and other entities exclusively owned by members of our founder's family; provided that, in each case, voting control with respect to the transferred shares of Class B common stock is retained by the transferring holder, members of our founder's family, a trustee of a trust primarily for the benefit of members of our founder's family or another fiduciary who is selected and may be replaced by the transferring holder. Each share of our Class B common stock will also convert automatically into one share of our Class A common stock if the voting power of all then-outstanding shares of our Class B common stock comes to represent less than ten percent of the combined voting power of all shares of our then-outstanding common stock. Once converted or transferred and converted into Class A common stock, the Class B common stock may not be reissued.

Preferred Stock

        Under the terms of our amended and restated certificate of incorporation that will become effective prior to the pricing of this offering, our board of directors is authorized to direct us to issue shares of preferred stock in one or more series without stockholder approval. Our board of directors has the discretion to determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock.

        The purpose of authorizing our board of directors to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock could adversely affect the voting power of holders of our common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions, future financings and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from seeking to acquire, a majority of our outstanding voting stock. Upon the closing of this offering, there will be no shares of preferred stock outstanding.

Registration Rights

        There will be no registration rights, except as otherwise provided in the Stockholders' Agreement. For more information, see "Certain Relationships and Related Party Transactions—Stockholders' Agreement."

Exclusive Jurisdiction

        Our amended and restated certificate of incorporation provides that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees to us or to our stockholders, any action asserting a claim governed by the internal affairs doctrine or any action asserting a claim arising pursuant to the General Corporation Law of the State of Delaware. Our amended and restated certificate of incorporation also provides that the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of

132


Table of Contents

action arising under the Securities Act. However, the enforceability of similar exclusive forum provisions (including exclusive federal forum provisions for actions, suits or proceedings asserting a cause of action arising under the Securities Act) in other companies' organizational documents has been challenged in legal proceedings, and there is uncertainty as to whether other courts would enforce the exclusive forum provisions in our certificate of incorporation. Additionally, our stockholders cannot waive compliance with the federal securities laws and the rules and regulations thereunder.

Anti-Takeover Provisions

        Our amended and restated certificate of incorporation, as it will be in effect immediately prior to the consummation of this offering, will contain provisions that may delay, defer or discourage another party from acquiring control of us. We expect that these provisions, which are summarized below, will discourage coercive takeover practices or inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors, which we believe may result in an improvement of the terms of any such acquisition in favor of our stockholders. However, they also give our board of directors the power to discourage acquisitions that some stockholders may favor. See "Risk Factors—Risks Related to This Offering and Ownership of Our Class A Common Stock—Anti-takeover provisions contained in our charter documents and Delaware law could prevent a takeover that stockholders consider favorable and could also reduce the market price of our stock."

Authorized but Unissued Shares

        The authorized but unissued shares of our common stock and our preferred stock are available for future issuance without stockholder approval, subject to any limitations imposed by the listing standards of the Nasdaq Global Market. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could make more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Classified Board of Directors

        Our amended and restated certificate of incorporation will provide that our board of directors will be divided into three classes, with the classes as nearly equal in number as possible and each class serving three-year staggered terms. So long as the holders of shares of our Class B common stock hold at least a majority of the voting power of the outstanding shares of our common stock, directors may be removed from our board of directors with or without cause by the affirmative vote of the holders of a majority in voting power of the shares entitled to vote. If the holders of shares of our Class B common stock no longer hold at least a majority of the voting power of the outstanding shares of our common stock, directors may only be removed from our board of directors for cause by the affirmative vote of the holders of a majority in voting power of the shares entitled to vote. See "Management—Board of Directors, Committees and Executive Officers." These provisions may have the effect of deferring, delaying or discouraging hostile takeovers or changes in control of us or our management.

Stockholder Action; Special Meeting of Stockholders

        Our amended and restated certificate of incorporation will provide that for so long as the holders of shares of Class B common stock hold at least a majority of the voting power of the outstanding shares of our common stock, our stockholders will be able to take actions by consent in lieu of a meeting, and, if the holders of shares of Class B common stock no longer hold at least a majority of the voting power of the outstanding shares of our common stock, our stockholders will not be able to take action by consent for any matter and may only take action at annual or special meetings. As a result, if the holders of shares of Class B common stock no longer hold at least a majority of the voting

133


Table of Contents

power of the outstanding shares or our common stock, a holder controlling a majority of our capital stock would not be able to amend our amended and restated bylaws or remove directors without holding a meeting of our stockholders called in accordance with our amended and restated bylaws, unless previously approved by our board of directors. Our amended and restated certificate of incorporation will further provide that special meetings of our stockholders may be called only by our board of directors, the chairperson of our board of directors, our chief executive officer or, for so long as any shares of Class B common stock remain outstanding, the holders of at least one third of the outstanding shares of our Class B common stock, thus limiting the ability of a stockholder to call a special meeting. These provisions might delay the ability of our stockholders to force consideration of a proposal or for stockholders controlling a majority of our capital stock to take any action, including the removal of directors.

Advance Notice Requirements for Stockholder Proposals and Director Nominations

        In addition, our amended and restated bylaws will establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of stockholders, including proposed nominations of candidates for election to our board of directors. In order for any matter to be "properly brought" before a meeting, a stockholder will have to comply with advance notice and duration of ownership requirements and provide us with certain information. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of our board of directors or by a qualified stockholder of record on the record date for the meeting who is entitled to vote at the meeting and who has delivered timely written notice in proper form to our secretary of the stockholder's intention to bring such business before the meeting. These provisions could have the effect of delaying stockholder actions that are favored by the holders of a majority of our outstanding voting securities until the next stockholder meeting.

Amendment of Certificate of Incorporation or Bylaws

        The DGCL provides generally that the affirmative vote of the holders of a majority in voting power of the shares entitled to vote is required to amend a corporation's certificate of incorporation, unless a corporation's certificate of incorporation requires a greater percentage. Upon consummation of this offering, our bylaws may be amended or repealed by a majority vote of our board of directors or by the affirmative vote of the holders a majority of the votes which all our stockholders would be eligible to cast in an election of directors.

Delaware Anti-Takeover Statute

        In general, Section 203 of the DGCL prohibits a public Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the time of the transaction in which the person became an interested stockholder, unless:

134


Table of Contents

        In general, Section 203 defines a "business combination" to include mergers, asset sales and other transactions resulting in financial benefit to a stockholder and an "interested stockholder" as a person who, together with affiliates and associates, owns, or, if such person is an affiliate or associate of the corporation within three years did own, 15% or more of the corporation's outstanding voting stock. These provisions may have the effect of delaying, deferring or preventing changes in control of our company.

        Under our amended and restated certificate of incorporation, we have opt out of Section 203 of the DGCL and will therefore not be subject to Section 203, unless and until (i) Section 203 by its terms would, but for the relevant provisions in our amended and restated certificate of incorporation, apply to the Company and (ii) no holder of shares of Class B common stock owns (as defined in Section 203) shares of the Company's capital stock representing as least 15% of the voting power of all the then-outstanding shares of capital stock of the Company; if at any time those criteria are met, the Company would thereafter be subject to Section 203.

Corporate Opportunity Doctrine

        Delaware law permits corporations to adopt provisions renouncing any interest or expectancy in certain opportunities that are presented to the corporation or its officers, directors or stockholders. Our amended and restated certificate of incorporation will, to the extent permitted by Delaware law, renounce any interest or expectancy that we have in, or right to be offered an opportunity to participate in, specified business opportunities that are from time to time presented to our officers, directors or stockholders or their respective affiliates, other than those officers, directors, stockholders or affiliates who are employees of the Company or its subsidiaries. Notwithstanding the foregoing, our amended and restated certificate of incorporation will not renounce our interest in any business opportunity that is expressly offered to an officer, director, stockholder or affiliate solely in their capacity as an officer, director or stockholder (or affiliate thereof).

Limitation on Liability of Directors and Indemnification

        Our amended and restated certificate of incorporation and amended and restated bylaws will limit our directors' and officers' liability to the fullest extent permitted under the General Corporation Law of the State of Delaware. Specifically, our directors and officers will not be liable to us or our stockholders for monetary damages for any breach of fiduciary duty by a director or officer, except for liability:

        If the General Corporation Law of the State of Delaware is amended to authorize corporate action further eliminating or limiting the personal liability of directors or officers, then the liability of our directors and officers shall be eliminated or limited to the fullest extent permitted by the General Corporation Law of the State of Delaware, as so amended.

135


Table of Contents

        The provision regarding indemnification of our directors and officers in our amended and restated certificate of incorporation will generally not limit liability under state or federal securities laws.

        Delaware law and our amended and restated certificate of incorporation and amended and restated bylaws will provide that we will, in certain situations, indemnify any person made or threatened to be made a party to a proceeding by reason of that person's former or present official capacity with our company against judgments, penalties, fines, settlements and reasonable expenses, including reasonable attorney's fees. Any person is also entitled, subject to certain limitations, to payment or reimbursement of reasonable expenses in advance of the final disposition of the proceeding. In addition, we are party to certain indemnification agreements pursuant to which we have agreed to indemnify the employees who are party thereto.

        The limitation of liability and indemnification provisions in our amended and restated certificate of incorporation may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. In addition, your investment may be adversely affected to the extent that, in a class action or direct suit, we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

Transfer Agent and Registrar

        The transfer agent and registrar for our Class A common stock will be Equiniti Trust Company.

Listing

        We have applied to list our Class A common stock on Nasdaq Global Market under the symbol "VERX."

SHARES ELIGIBLE FOR FUTURE SALE

        Prior to this offering, there has been no public market for our Class A common stock, and we cannot predict the effect, if any, that market sales of shares of our Class A common stock or the availability of shares of our Class A common stock for sale will have on the market price of our Class A common stock prevailing from time to time. Future sales of our Class A common stock in the public market, or the availability of such shares for sale in the public market, could adversely affect market prices prevailing from time to time. As described below, only a limited number of shares of Class A common stock will be available for sale shortly after this offering due to contractual and legal restrictions on resale. Nevertheless, sales of our Class A common stock in the public market after such restrictions lapse, or the perception that those sales may occur, could adversely affect the prevailing market price at such time and our ability to raise equity capital in the future.

        After giving effect to the reclassification, based on the number of shares outstanding as of June 30, 2020, upon the completion of this offering, 22,576,819 shares of Class A common stock (25,749,319 shares of Class A common stock if the underwriters exercise their option to purchase additional shares of Class A common stock in full) and 120,417,000 shares of Class B common stock will be outstanding. Of the outstanding shares, all the shares of Class A common stock sold in this offering, including both the shares sold by us and any shares sold by the selling stockholders as a result of the underwriters' exercise of their option to purchase additional shares, will be freely transferrable without restriction or registration under the Securities Act, except that any shares purchased by one of our "affiliates," as that term is defined in Rule 144 under the Securities Act may be sold only in compliance with the limitations described below, and any shares purchased by our directors or officers pursuant to our directed share program shall be subject to the lock-up agreements described below.

        The shares of Class B common stock outstanding upon completion of this offering will be restricted securities, as that term is defined in Rule 144 under the Securities Act. These shares of Class B common stock may be sold in the public market only if registered or pursuant to an exemption from registration, such as Rule 144 or Rule 701 under the Securities Act, which are summarized below.

Lock-Up Agreements

        All of our directors and executive officers, the selling stockholders and the holders of substantially all of our capital stock have entered into lock-up agreements under which they agree, subject to certain exceptions, not to sell, transfer or dispose of, directly or indirectly, any shares of our Class A common stock or any securities convertible into or exercisable or exchangeable for shares of our Class A common stock for a period of 180 days after the date of this prospectus. The restrictions described above do not apply to the sales of shares of Class A common stock by us and, to the extent the underwriters exercise their option to purchase additional shares, the selling stockholders, to the underwriters in this offering. Goldman Sachs & Co. LLC and Morgan Stanley & Co. LLC may, in their sole discretion, permit our stockholders who are subject to these lock-up agreements to sell shares prior to the expiration of the lock-up agreements. See "Underwriting" for a description of these agreements.

Rule 144

        In general, under Rule 144 as currently in effect, once we have been subject to the public company reporting requirements of Section 13 or Section 15(d) of the Exchange Act for at least 90 days, a person who is not deemed to have been one of our affiliates for purposes of the Securities Act at any time during the 90 days preceding a sale and who has beneficially owned the shares of our Class A common stock proposed to be sold for at least six months is entitled to sell those shares without complying with the manner of sale, volume limitation or notice provisions of Rule 144, subject to compliance with the public information requirements of Rule 144. If such a person has beneficially owned the shares of Class A common stock proposed to be sold for at least one year, including the

137


Table of Contents

holding period of any prior owner other than our affiliates, then that person would be entitled to sell those shares of Class A common stock without complying with any of the requirements of Rule 144.

        In general, under Rule 144, as currently in effect, our affiliates or persons selling shares of our Class A common stock on behalf of our affiliates are entitled to sell upon expiration of the lock-up agreements described above, within any three-month period, a number of shares of Class A common stock that does not exceed the greater of:

        Sales under Rule 144 by our affiliates or persons selling shares of our Class A common stock on behalf of our affiliates are also subject to certain manner-of-sale provisions and notice requirements and to the availability of current public information about us.

Rule 701

        Rule 701 generally allows a stockholder who purchased shares of our capital stock pursuant to a written compensatory plan or contract and who is not deemed to have been an affiliate of our company during the immediately preceding 90 days to sell these shares in reliance upon Rule 144, but without being required to comply with the public information, holding period, volume limitation or notice provisions of Rule 144. Rule 701 also permits affiliates of our company to sell their Rule 701 shares under Rule 144 without complying with the holding period requirements of Rule 144. All holders of Rule 701 shares, however, are required to wait until 90 days after the date of this prospectus before selling those shares pursuant to Rule 701. Moreover, all Rule 701 shares are subject to lock-up agreements with the underwriters as described above and in the section titled "Underwriting" and will not become eligible for sale until the expiration of those agreements.

Registration Rights

        The parties to the Stockholders Agreement, who collectively own all of the shares of our Class B common stock, are entitled to certain rights with respect to the registration of those shares under the Securities Act. For a description of these registration rights, see "Certain Relationships and Related Party Transactions—Stockholders' Agreement." If these shares are registered, in most cases they will be freely tradable without restriction under the Securities Act, and a large number of shares may be sold into the public market.

Registration Statement on Form S-8

        We have filed a registration statement on Form S-8 under the Securities Act to register shares of our Class A common stock subject to awards outstanding, as well as reserved for future issuance, under our equity compensation plans. The registration statement on Form S-8 became effective immediately upon filing, and shares of our Class A common stock covered by the registration statement will then become eligible for sale in the public market, subject to the Rule 144 limitations applicable to affiliates, vesting restrictions and any applicable lock-up agreements.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS

        The following discussion is a summary of the material U.S. federal income tax consequences to Non-U.S. Holders (as defined below) of the purchase, ownership and disposition of our Class A common stock issued pursuant to this offering, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the Code, Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the "IRS"), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a Non-U.S. Holder of our Class A common stock. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance that the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership and disposition of our common stock.

        This discussion is limited to Non-U.S. Holders that hold our Class A common stock as a "capital asset" within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a Non-U.S. Holder's particular circumstances, including the impact of the Medicare contribution tax on net investment income. In addition, it does not address consequences relevant to Non-U.S. Holders subject to special rules, including, without limitation:

        If an entity treated as a partnership for U.S. federal income tax purposes holds our Class A common stock, the tax treatment of a partner in the partnership will depend on the status of the

139


Table of Contents

partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding our Class A common stock and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

        THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR CLASS A COMMON STOCK ARISING UNDER U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Definition of a Non-U.S. Holder

        For purposes of this discussion, a "Non-U.S. Holder" is any beneficial owner of our Class A common stock that is neither a "U.S. person" nor an entity treated as a partnership for U.S. federal income tax purposes. A U.S. person is any person that, for U.S. federal income tax purposes, is or is treated as any of the following:

Distributions

        As described in the section entitled "Dividend Policy," we do not anticipate declaring or paying dividends to holders of our Class A common stock in the foreseeable future. However, if we do make distributions of cash or property on Class A our common stock, such distributions will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a Non-U.S. Holder's adjusted tax basis in its Class A common stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below under "—Sale or Other Taxable Disposition."

        Subject to the discussion below on effectively connected income, dividends paid to a Non-U.S. Holder of our Class A common stock will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the Non-U.S. Holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). If the Non-U.S. Holder holds the stock through a financial institution or other agent acting on the holder's behalf, the holder will be required to provide appropriate documentation to the agent. The holder's agent will then be required to provide certification to us or our paying agent, either directly or through other intermediaries. A Non-U.S. Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

140


Table of Contents

        If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States.

        Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular graduated rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected dividends, as adjusted for certain items. Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Sale or Other Taxable Disposition

        A Non-U.S. Holder will not be subject to U.S. federal income tax on any gain realized upon the sale or other taxable disposition of our Class A common stock unless:

        Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular graduated rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

        Gain described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

        With respect to the third bullet point above, we believe we currently are not, and do not anticipate becoming, a USRPHC. Because the determination of whether we are a USRPHC depends, however, on the fair market value of our USRPIs relative to the fair market value of our non-U.S. real property interests and our other business assets, there can be no assurance we currently are not a USRPHC or will not become one in the future. Even if we are or were to become a USRPHC, gain arising from the sale or other taxable disposition by a Non-U.S. Holder of our Class A common stock will not be subject to U.S. federal income tax if our Class A common stock is "regularly traded," as defined by applicable Treasury Regulations, on an established securities market, and such Non-U.S. Holder owned, actually and constructively, 5% or less of our Class A common stock throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition or the Non-U.S. Holder's holding period.

141


Table of Contents

        Non-U.S. Holders should consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

        Payments of dividends on our Class A common stock will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person and the holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any dividends on our Class A common stock paid to the Non-U.S. Holder, regardless of whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of our Class A common stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting, if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a United States person, or the holder otherwise establishes an exemption. Proceeds of a disposition of our Class A common stock conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

        Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

        Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder's U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Additional Withholding Tax on Payments Made to Foreign Accounts

        Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act, or "FATCA") on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on, or (subject to the proposed Treasury Regulations discussed below) gross proceeds from the sale or other disposition of, our Class A common stock paid to a "foreign financial institution" or a "non-financial foreign entity" (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any "substantial United States owners" (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain "specified United States persons" or "United States owned foreign entities" (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

        Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our Class A common stock. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of stock on or after January 1, 2019, recently proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued.

        Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our Class A common stock.

        Subject to the terms and conditions set forth in the Underwriting Agreement, the underwriters have agreed, severally and not jointly, to purchase all of the shares sold under the Underwriting Agreement if any of these shares are purchased, other than the shares covered by the option described below unless and until this option is exercised. If an underwriter defaults, the Underwriting Agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the Underwriting Agreement may be terminated.

        We and the selling stockholders have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

        The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officers' certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Option to Purchase Additional Shares

        We and the selling stockholders have granted an option to the underwriters, exercisable for 30 days after the date of this prospectus, to purchase up to 3,172,500 additional shares at the public offering price, less underwriting discounts and commissions. Of these shares, 510,284 will be sold by selling stockholders. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the Underwriting Agreement, to purchase a number of additional shares proportionate to that underwriter's initial amount reflected in the above table.

Commissions and Discounts

        The representatives have advised us that the underwriters propose initially to offer the shares to the public at the public offering price set forth on the cover page of this prospectus and to dealers at that price less a concession not in excess of $0.684 per share. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

        The expenses of the offering, not including underwriting discounts and commissions, are estimated at $6,345,000 and are payable by us. The Company has agreed to reimburse the underwriters for certain out-of-pocket expenses in connection with this offering in an amount not to exceed $50,000.

No Sales of Similar Securities

        We, our executive officers and directors, the selling stockholders and the holders of substantially all of our outstanding capital stock have agreed, that, without the consent of the representatives on behalf of the underwriters, we and they will not, during the period ending 180 days after the date of this prospectus, or the restricted period:

        The restrictions described above do not apply to (i) the sale of shares of Class A common stock to the underwriters in this offering, (ii) open market transactions after completion of this offering, and (iii) transfers of the Company's Class A common stock:

144


Table of Contents

        This lock-up provision applies to Class A common stock and to securities convertible into or exchangeable or exercisable for or repayable with Class A common stock. It also applies to Class A common stock owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition.

Exchange Listing

        Our Class A common stock has been approved for listing on the Nasdaq Global Market under the symbol "VERX." In order to meet the requirements for listing on that exchange, the underwriters have undertaken to sell a minimum number of shares to a minimum number of beneficial owners as required by that exchange.

        Before this offering, there has been no public market for our Class A common stock. The initial public offering price was determined through negotiations between us and the representatives. In addition to prevailing market conditions, the factors to be considered in determining the initial public offering price are:

145


Table of Contents

        An active trading market for the shares may not develop. It is also possible that after the offering the shares will not trade in the public market at or above the initial public offering price.

        The underwriters do not expect to sell more than 5% of the shares in the aggregate to accounts over which they exercise discretionary authority.

Price Stabilization, Short Positions and Penalty Bids

        Until the distribution of the shares is complete, SEC rules may limit underwriters and selling group members from bidding for and purchasing our Class A common stock. However, the representatives may engage in transactions that stabilize the price of the Class A common stock, such as bids or purchases to peg, fix or maintain that price.

        In connection with the offering, the underwriters may purchase and sell our Class A common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering. "Covered" short sales are sales made in an amount not greater than the underwriters' option to purchase additional shares described above. The underwriters may close out any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the option granted to them. "Naked" short sales are sales in excess of such option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our Class A common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares of Class A common stock made by the underwriters in the open market prior to the completion of the offering.

        The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discounts and commissions received by it because the representatives have repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.

        Similar to other purchase transactions, the underwriters' purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our Class A common stock or preventing or retarding a decline in the market price of our Class A common stock. As a result, the price of our Class A common stock may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on the Nasdaq Global Market, in the over-the-counter market or otherwise.

        Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our Class A common stock. In addition, none of us or any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Electronic Distribution

        In connection with the offering, certain of the underwriters or securities dealers may distribute prospectuses by electronic means, such as e-mail. In addition, the underwriters may facilitate internet distribution for this offering to certain of their respective internet subscription customers. The underwriters may allocate a limited number of shares of common stock for sale to their respective online brokerage customers. An electronic prospectus is available on internet websites maintained by

146


Table of Contents

the underwriters. Other than the prospectus in electronic format, the information on the website of the underwriters is not part of this prospectus.

Other Relationships

        Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates for which they have received, or may in the future receive, customary fees and commissions for these transactions.

        In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Directed Share Program

        At our request, the underwriters have reserved for sale, at the initial public offering price, up to 5% of the Class A common stock offered by this prospectus for sale to some of our directors, officers, employees, business associates and related persons. If these persons purchase reserved shares, it will reduce the number of shares available for sale to the general public. Any reserved shares that are not so purchased will be offered by the underwriters to the general public on the same terms as the other shares offered by this prospectus.

LEGAL MATTERS

        The validity of the shares of Class A common stock offered hereby will be passed upon for us by Latham & Watkins LLP, Washington, D.C. The underwriters are being represented by Skadden, Arps, Slate, Meagher & Flom LLP in connection with this offering.


EXPERTS

        The consolidated financial statements of the Company at December 31, 2019 and 2018 and for each of the two years in the period ended December 31, 2019 have been audited by Crowe LLP, independent registered public accounting firm, as set forth in its report thereon appearing elsewhere herein, and are included in reliance upon such report given on the authority of such firm as experts in accounting and auditing.


CHANGE IN INDEPENDENT ACCOUNTANT

        On October 8, 2019, our board of directors determined to dismiss Baker Tilly Virchow Krause, LLP ("Baker Tilly"). Our board of directors retained Crowe LLP as our independent public accounting firm on December 4, 2019.

        The reports of Baker Tilly on our consolidated financial statements for each of the two fiscal years prior to its dismissal did not contain any adverse opinion or disclaimer of opinion, nor were such reports qualified or modified as to uncertainty, audit scope or accounting principles. We had no disagreements with Baker Tilly on any matter of accounting principles or practices, consolidated financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to its satisfaction, would have caused Baker Tilly to make reference in connection with its opinion to the subject matter of the disagreement during its audits for each of the two fiscal years prior to its dismissal or the subsequent interim period through October 8, 2019. During the two most recent fiscal years preceding Baker Tilly's dismissal, and the subsequent interim period through October 8, 2019, there were no "reportable events" as such term is defined in Item 304(a)(1)(v) of Regulation S-K.

        During the two years ended December 31, 2018 and the subsequent interim period through December 4, 2019, neither we, nor anyone acting on our behalf, consulted with Crowe LLP on matters that involved the application of accounting principles to a specified transaction, either completed or proposed, the type of audit opinion that might be rendered on our consolidated financial statements, and neither a written report nor oral advice was provided to us by Crowe LLP.

        We have provided Baker Tilly with a copy of the foregoing disclosure and have requested that Baker Tilly furnish us with a letter addressed to the SEC stating whether or not Baker Tilly agrees with the above statements and, if not, stating the respects in which it does not agree. A copy of the letter from Baker Tilly has been filed as an exhibit to the registration statement of which this prospectus is a part.

Opinion on the Financial Statements

        We have audited the accompanying consolidated balance sheets of Vertex, Inc. (the "Company") as of December 31, 2019 and 2018, the related consolidated statements of comprehensive income (loss), changes in equity, and cash flows for the years then ended, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

        These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

        We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

        Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

    /s/ Crowe LLP

We have served as the Company's auditor since 2019.

Notes to Consolidated Financial Statements

December 31, 2019 and 2018 and
March 31, 2020 and 2019 (unaudited)

(Amounts in thousands, except per share data)

1. Summary of significant accounting policies

        Vertex, Inc. ("Vertex") and its direct and indirect wholly-owned subsidiaries (collectively, the "Company") operate as solutions providers of state, local and value added tax calculation, compliance and analytics, offering software products which are sold through software license and software as a service ("cloud") subscriptions. The Company also provides implementation and training services in connection with its software license and cloud subscriptions, transaction tax returns outsourcing, and other tax-related services. The Company sells to customers located throughout the United States of America ("U.S.") and internationally.

        The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and include the accounts of the Company. All intercompany transactions have been eliminated in consolidation.

        Effective January 7, 2020, the Company acquired a 60% controlling interest in Systax Sistemas Fiscais LTDA ("Systax"), a provider of Brazilian transaction tax content and software. Systax is considered a Variable Interest Entity ("VIE") and its accounts have been included in the consolidated financial statements from the acquisition date. Systax was determined to be a VIE as Vertex is the primary beneficiary of the equity interests in Systax and participates significantly in the variability in the fair value of Systax's net assets. Although Vertex does not have full decision-making authority as it is shared with the minority interest owners, as the minority interest owners are considered a related party, Vertex is considered the most closely associated party to Systax and is required to consolidate. Systax's assets may only be used to settle its own obligations and this will continue until such time as Vertex owns 100% of the VIE. As of March 31, 2020, the net assets of Systax were $20,550 (unaudited). Vertex is at risk to the extent of its current 60% ownership of Systax, which risk will increase over time in proportion to increases in percentage ownership as Vertex exercises its future share purchase commitment through 2023. See Note 2.

        The accompanying interim consolidated balance sheet as of March 31, 2020 and the consolidated interim statements of comprehensive income (loss), cash flows, and changes in equity during the three months ended March 31, 2020 and 2019 are unaudited. The unaudited interim consolidated financial statements have been prepared on a basis consistent with the annual audited financial statements consolidated and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company's financial position as of March 31, 2020 and its results of operations, comprehensive income (loss) and cash flows for the three months ended March 31, 2020 and 2019. The interim results of operations for the three months ended March 31, 2020 and 2019 are not necessarily indicative of the results to be expected for the full fiscal year or for any other future annual or interim periods.

1. Summary of significant accounting policies (Continued)

        The Company operates its business as one operating segment. Operating segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the chief operating decision maker ("CODM"), the Company's Chief Executive Officer, in deciding how to allocate resources and assess performance. The Company's CODM allocates resources and assesses performance based upon discrete financial information at the consolidated level. For the years ended December 31, 2019 and 2018 approximately 4% and 3% of the Company's revenue were generated outside of the United States, respectively. For the three months ended March 31, 2020 and 2019 approximately 3% and 3% of the Company's revenue was generated outside of the United States, respectively (unaudited). As of December 31, 2019 and 2018, none of the Company's long-lived assets were held outside of the U.S. As of March 31, 2020, 19%, or $20,518, of the Company's long-lived assets were held outside of the U.S. (unaudited) and consists primarily of goodwill of $20,231 (unaudited) at March 31, 2020 related to the acquisition of the controlling interest in Systax, which is located in Brazil. See Note 2.

        Financial instruments that potentially subject the Company to credit risk consist principally of cash and cash equivalents, funds held for customers, accounts receivable and investment securities.

        The Company maintains the majority of its cash and cash equivalent balances and funds held for customers in four banks. These amounts exceed federally-insured ("FDIC") limits. The Company periodically evaluates the creditworthiness of the banks. The Company has not experienced any losses in these accounts and believes they are not exposed to significant credit risk on such accounts.

        The Company does not require collateral from its customers. Allowances are maintained for subscription cancellations. Credit risk related to accounts receivable is limited due to the industry and geographic diversity within the Company's customer base. No single customer accounted for more than 10% of revenues for the years ended December 31, 2019 and 2018 or for the three months ended March 31, 2020 and 2019 (unaudited).

        The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, funds held for customers, accounts receivable, accounts payable, accrued expenses and debt approximate their related fair values.

        The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, equity, revenues and expenses during the reporting period. Significant estimates used in preparing these consolidated financial statements include: (i) the estimated allowance for subscription cancellations, (ii) the reserve for self-insurance, (iii) assumptions related to achievement of technological feasibility for software developed for sale, (iv) product life cycles, (v) estimated useful lives and potential impairment of long-lived assets,

intangible assets and goodwill, (vi) determination of the fair value of tangible and intangible assets acquired, liabilities assumed and consideration transferred in an acquisition, (vii) amortization period of material rights and deferred commissions (viii) valuation for the Company's stock used for stock-based compensation, and (ix) the potential outcome of future tax consequences of events that have been recognized in the consolidated financial statements or tax returns. Actual results may differ from these estimates.

        The Company considers all highly liquid investments purchased with an initial maturity date of three months or less to be cash equivalents.

        Funds held for stockholder distributions of $110,000 at March 31, 2020 is reserved for distribution to stockholders to be paid within 90 days of March 31, 2020, the closing date of the new credit agreement, and is reflected in noncurrent assets in the consolidated balance sheet. If a distribution is not made within this time frame, such amount must be repaid to the bank.

        Funds held for customers in the consolidated balance sheets represents customer funds advanced for transaction tax returns outsourcing. Funds held for customers are restricted for the sole purpose of remitting such funds to satisfy obligations on behalf of such customers and are deposited at FDIC-insured institutions. Customer obligations are included in current liabilities in the consolidated balance sheets, as the obligations are expected to be settled within one year.

        Property and equipment are stated at cost or fair value when acquired and presented net of accumulated depreciation. Normal maintenance and repairs are charged to expense, while major renewals and betterments are capitalized. Assets under capital leases are recorded at the lower of the present value of the minimum lease payments or the fair value of the assets and are depreciated over the shorter of the asset's useful life or lease term. Depreciation and amortization are computed straight-line over the estimated useful lives of the assets, as follows:

Leasehold improvements

  1 - 12 years

Equipment

  3 - 10 years

Computer software

  3 - 7 years

Software Development Costs

        The Company follows Accounting Standard Codification ("ASC") 350-40, Goodwill and Other, Internal-Use Software, to account for development costs incurred for the costs of computer software developed or obtained for internal use. ASC 350-40 requires such costs to be capitalized once certain criteria are met. Capitalized internal-use software costs are primarily comprised of direct labor, related expenses and initial software licenses. ASC 350-40 includes specific guidance on costs not to be capitalized, such as overhead, general and administrative and training costs. Internal-use software includes software utilized for cloud-based solutions as well as software for internal systems and tools. Costs are capitalized once the project is defined, funding is committed and it is confirmed the software will be used for its intended purpose. Capitalization of these costs concludes once the project is substantially complete and the software is ready for its intended purpose. Post-configuration training and maintenance costs are expensed as incurred. Internal-use software is included in internal-use software developed in property and equipment in the consolidated balance sheets once available for its intended use and is depreciated over periods between 3 to 5 years. Depreciation expense for internal-use software utilized for cloud-based solutions and for software for internal systems and tools is included in cost of revenues, software subscriptions and depreciation expense, respectively, in the consolidated statements of comprehensive income (loss).

        The costs incurred for the development of computer software to be sold, leased, or otherwise marketed are capitalized in accordance with ASC 985-20, Costs of Software to be Sold, Leased or Marketed, when technological feasibility has been established. Technological feasibility generally occurs when all planning, design, coding and testing activities are completed that are necessary to establish that the product can be produced to meet its design specifications, including functions, features and technical performance requirements. The establishment of technological feasibility is an ongoing assessment of judgment by management with respect to certain external factors, including, but not limited to, anticipated future revenues, estimated economic life and changes in technology. Capitalized software includes direct labor and related expenses for software development for new products and enhancements to existing products and acquired software.

        Amortization of capitalized software development costs begins when the product is available for general release. Amortization is provided on a product-by-product basis using the straight-line method over periods between 3 to 5 years. Unamortized capitalized software development costs determined to be in excess of the net realizable value of the product are expensed immediately.

        Capitalized software costs are subject to an ongoing assessment of recoverability based on anticipated future revenues and changes in software technologies. At each balance sheet date, unamortized capitalized software costs are compared to the net realizable value of the related product. The carrying value of the related assets are written down to the net realizable value to the extent the unamortized capitalized costs exceed such value. The net realizable value is the estimated future gross

revenues from the related product reduced by the estimated future costs of completing and disposing of such product, including the costs of providing related maintenance and customer support.

        The Company reviews the carrying value of long-lived assets, including internal-use software, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. Whenever such events or circumstances are present, an impairment loss equal to the excess of the asset carrying value over its fair value, if any, is recorded.

        Upon acquisition of a company, the Company determines if the transaction is a business combination, which is accounted for using the acquisition method of accounting. Under the acquisition method, once control is obtained of a business, the assets acquired, liabilities assumed, consideration transferred and amounts attributed to noncontrolling interests, are recorded at fair value. The Company uses its best estimates and assumptions to assign fair value to the tangible and intangible assets acquired, liabilities assumed, consideration transferred and amounts attributed to noncontrolling interests at the acquisition date. One of the most significant estimates relates to the determination of the fair value of these assets and liabilities. The determination of the fair values is based on estimates and judgments made by Management. The Company's estimates of fair value are based upon assumptions it believes to be reasonable, but which are inherently uncertain and unpredictable. Measurement period adjustments to these values as of the acquisition date are reflected at the time identified, up through the conclusion of the measurement period, which is the time at which all information for determination of the values of assets acquired, liabilities assumed, consideration transferred and noncontrolling interests is received, and is not to exceed one year from the acquisition date (the "Measurement Period"). The Company may record adjustments to the fair value of these tangible and intangible assets acquired, liabilities assumed, consideration transferred and noncontrolling interests, with the corresponding offset to goodwill. Additionally, uncertain tax positions and tax-related valuation allowances are initially recorded in connection with a business combination as of the acquisition date. The Company continues to collect information and reevaluate these estimates and assumptions periodically and record any adjustments to preliminary estimates to goodwill, provided the Company is within the Measurement Period with any adjustments to amortization of new or previously recorded identifiable intangibles being recorded to the consolidated statements of comprehensive income (loss) in the period in which they arise. In addition, if outside of the Measurement Period, any subsequent adjustments to the acquisition date fair values are recorded to the consolidated statements of comprehensive income (loss) in the period in which they arise.

        Goodwill represents the excess of the purchase price over the fair value of net tangible and intangible assets acquired in a business combination. The Company evaluates goodwill for impairment annually at December 31 and whenever events or circumstances make it more likely than not that impairment may have occurred. The Company has determined that its business comprises one reporting

unit. The Company has the option to first assess qualitative factors to determine whether events or circumstances indicate it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, in which case a quantitative impairment test is not required.

        The quantitative goodwill impairment test is performed by comparing the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not impaired. An impairment loss is recognized for any excess of the carrying amount of the reporting unit's goodwill over the fair value up to the amount of goodwill allocated to the reporting unit. Income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit are considered when measuring the goodwill impairment loss, if applicable.

        The changes in goodwill for the three months ended March 31, 2020 are as follows:

Balance, January 1, 2020

Acquisition of Systax

    26,124

        The Company capitalizes costs related to obtaining, renewing or extending loan agreements and amortizes these costs on a straight-line basis, which approximates the interest method, over the life of the loan. Deferred financing costs related to outstanding borrowings under bank debt are reflected as a reduction of current portion of long-term debt and long-term debt, net of current portion. Deferred financing costs related to undrawn debt are reflected in deposits and other assets in the consolidated balance sheets in accordance with ASC 835-30, Interest—Imputation of Interest.

        The Company applies the provisions of ASC 718, Compensation—Stock Compensation, for the award of equity-based instruments. The provisions of ASC 718 require a company to measure the fair value of stock-based compensation as of the grant date of the award. The Company has stock options and stock appreciation rights ("SAR(s)") (collectively, the "awards") outstanding that are subject to guidance set forth in ASC 718. The Company's Board of Directors (the "Board") intends all awards granted to be exercisable at a price per share not less than the per share fair value of the Company's common stock underlying such awards on the date of grant. Stock-based compensation expense reflects the cost of employee services received in exchange for the awards.

        SARs are accounted for as liabilities under ASC 718 and, as such, the Company recognizes stock-based compensation expense by remeasuring the SARs at the end of each reporting period and accruing the portion of the requisite service rendered at that date. As a nonpublic entity, the Company has elected to measure SARs based on their intrinsic values. Management measures the intrinsic value of the SARs as the difference between the fair value of the Company's Class B common stock less the

1. Summary of significant accounting policies (Continued)

grant date fair value of the underlying shares as this is the value the SAR participant can derive from exercise of the SAR award. The fair value of the Company's common stock is determined periodically by the Board with the assistance of management and a third-party valuation firm. Management plans to continue to record changes in the intrinsic value of the SARs in 2020 up to the date on which the Company becomes a public entity. Upon becoming a public entity and thereafter, Management will remeasure SARs using the fair value-based method under ASC 718. Any impact from such change in measurement on the date on which the Company becomes a public entity will be accounted for as a change in accounting policy in that period. To the extent the fair value-based measure of the SARs differs materially from the intrinsic value of the SARs, this effect could be material. As the fair value-based measure of the SARs is not determinable at this time, such amount cannot be reasonably estimated with any degree of certainty. Outstanding SARs are included in deferred compensation, current and deferred compensation, net of current portion in the consolidated balance sheets.

        Due to the option holders having the right to require the Company to repurchase shares issued in connection with option exercises after six months of share issuance, the options are classified as temporary equity and reflected in options for redeemable shares on the consolidated balance sheets at their redemption value, which equals the options' intrinsic value, as of the end of each balance sheet measurement period. Changes as a result of remeasurement of the redemption value of options for redeemable shares are recorded as adjustments to accumulated deficit.

        The fair value of the common stock underlying the awards is determined by the Board with assistance from management and an independent third-party valuation firm. The determination of value uses the market and income approaches, with an adjustment for marketability discount in arriving at the per share fair value (the "valuation methodology"). Under the market approach, the guideline public company method is used, which estimates the fair value of the Company based on market prices of stock of guideline public companies. The income approach involves projecting the future benefits of owning an asset and estimating the present value of those future benefits by discounting them based upon the time value of money and the investment risks associated with ownership. At the end of 2019, due to the consideration by the Board of pursuing an initial public offering of the Company's common stock during 2020 (the "Offering"), the valuation methodology began to consider the impact of such an event on the value of the Company's common stock underlying the awards. As the Company approaches the Offering, Management expects this will result in an increase in the intrinsic value of the awards that will correspondingly result in increases to compensation expense in the consolidated comprehensive statements of income during 2020 that exceed historical results.

        Rent expense for operating leases is recognized on a straight-line basis over the period of the related lease. For lease agreements that include future specific rent increases, rent concessions and/or tenant improvement allowances, the difference between the rent payments and the straight-line rent expense is included in deferred rent liability in the consolidated balance sheets.

        The Company is self-insured for the majority of its health insurance costs, including medical claims subject to certain stop-loss provisions. Management periodically reviews the adequacy of the Company's stop-loss insurance coverage. The Company records an estimate of claims incurred but not reported, based on management's judgment and historical experience. Self-insurance accruals are $1,473 and $1,408 at December 31, 2019 and 2018, respectively, and $1,663 at March 31, 2020 (unaudited), and are reflected in accrued salaries and benefits in the consolidated balance sheets. Material differences may result in the amount and timing of insurance expense if actual experience differs significantly from management's estimates.

Revenue Recognition

        On January 1, 2018, the Company adopted Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers, ("ASC 606"). Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration expected to be received in exchange for those products or services. The Company enters into contracts that can include various combinations of products and services, which are generally capable of being distinct, and accounted for as separate performance obligations. Revenue is recognized net of allowance for subscription and non-renewal cancellations and any taxes collected from customers, which are subsequently remitted to governmental authorities.

        Licenses for on-premise software subscriptions provide the customer with a right to use the software as it exists when made available to the customer. Customers purchase a subscription to these licenses, which includes the related software and tax content updates (collectively "updates") and product support. The updates and support, which are part of the subscription agreement, are essential to the continued utility of the software; therefore, the Company has determined the software and the related updates and support to be a single performance obligation. Accordingly, when on-premise software is licensed, the revenue associated with this combined performance obligation is recognized ratably over the license term as these subscriptions are provided for the duration of the license term. Revenue recognition begins on the later of the beginning of the subscription period or the date the software is made available to the customer to download. The Company's on-premise software subscription prices in the initial subscription year are higher than standard renewal prices. The excess initial year price over the renewal price ("new sale premium") is a material right that provides customers with the right to this reduced renewal price. The Company recognizes revenue associated with this material right over the estimated period of benefit to the customer, which is generally three years.

        Cloud-based subscriptions allow customers to use Company-hosted software over the contract period without taking possession of the software. The cloud-based offerings also include related updates and support. Cloud-based contracts consistently provide a benefit to the customer during the

subscription period, thus the associated revenue is recognized ratably over the related subscription period. Revenue recognition begins on the later of the beginning of the subscription period or the date the customer is provided access to the cloud-based solutions.

        Revenue from deliverable-based services is recognized as services are delivered. Revenue from fixed fee services is recognized as services are performed using the percentage of completion input method.

        The Company has elected the "right to invoice" practical expedient for revenue related to services that are billed on an hourly basis, which enables revenue to be recognized as the services are performed.

        The Company has determined that the methods applied to measuring its progress toward complete satisfaction of performance obligations recognized over time are a faithful depiction of the transfer of control of software subscriptions and services to customers.

        Contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. Identification of the amortization periods of material rights and contract costs requires significant judgement by management.

        The table reflects revenue by major source for the following periods:

        Timing of revenue recognition may differ from the timing of invoicing customers. A receivable is recorded in the consolidated balance sheets when customers are billed related to revenue to be collected and recognized for subscription agreements as there is an unconditional right to invoice and receive payment in the future related to these subscriptions. A receivable and related revenue may also be recorded in advance of billings to the extent services have been performed and the Company has a right under the contract to bill and collect for such performance. Subscription-based customers are

generally invoiced annually at the beginning of each annual subscription period. Accounts receivable is presented net of an allowance for potentially uncollectible accounts and estimated cancellations of software license and cloud-based subscriptions (the "allowance") of $7,515 and $5,527 at December 31, 2019 and 2018, respectively, and $7,476 at March 31, 2020 (unaudited).

        A contract liability is recorded as deferred revenue on the consolidated balance sheets when customers are billed in advance of performance obligations being satisfied, and revenue is recognized after invoicing ratably over the subscription period or over the amortization period of material rights. Deferred revenue is reflected net of a related deferred allowance for subscription cancellations (the "deferred allowance") of $5,614 and $4,858 at December 31, 2019 and 2018, respectively, and $5,118 at March 31, 2020 (unaudited).

        Deferred sales commissions earned by the Company's sales force and certain sales incentive programs and vendor referral agreements are considered incremental and recoverable costs of obtaining a contract with a customer. An asset is recognized for these incremental contract costs and reflected as deferred commissions in the consolidated balance sheets. These contract costs are amortized on a straight-line basis over a period consistent with the transfer of the associated product and services to the customer, which is generally three years. Amortization of these costs are included in selling and marketing expense in the consolidated statements of comprehensive income (loss). The Company periodically reviews these contract assets to determine whether events or changes in circumstances have occurred that could impact the period of benefit of these assets. There were no impairment losses recorded for the periods presented.

        Payment terms and conditions vary by contract, although the Company's terms generally include a requirement of payment within 30 days. In instances where the timing of revenue recognition differs from the timing of payment, the Company has determined that its contracts do not include a significant financing component. The primary purpose of invoicing terms is to provide customers with simplified and predictable ways of purchasing products and services, not to receive financing from customers or to provide customers with financing.

        Cost of revenues, software subscriptions includes the direct cost to develop, host and distribute software products, the direct cost to provide customer support, and amortization of costs capitalized for software developed for sale and for internal-use software utilized for cloud-based subscriptions. Cost of revenues, services includes the direct costs of implementation, training, transaction tax returns outsourcing and other tax-related services.

        Reimbursable costs passed through and invoiced to customers of the Company are recorded as services revenues with the associated expenses recorded as cost of revenues, services in the consolidated statements of comprehensive income (loss). These amounts were $1,107 and $902 for the years ended December 31, 2019 and 2018, respectively, and $185 and $220 for the three months ended March 31, 2020 and 2019, respectively (unaudited).

        Research and development costs consist primarily of personnel and related expenses for research and development activities including salaries, benefits and other compensation. Research and development costs are expensed as incurred in accordance with ASC 730, Research and Development, and are included in the consolidated statements of comprehensive income (loss).

        Advertising expense is recorded as incurred and is reflected in selling and marketing expense in the consolidated statements of comprehensive income (loss). Total advertising expense was $11,921 and $8,956 for the years ended December 31, 2019 and 2018, respectively, and $1,523 and $1,787 for the three months ended March 31, 2020 and 2019, respectively (unaudited).

        The Company transacts business in various foreign currencies. Management has concluded that the local country's currency is the functional currency of its foreign operations. Consequently, operating activities outside the U.S. are translated into U.S. Dollars using average exchange rates, while assets and liabilities of operations outside the U.S. are translated into U.S. Dollars using exchange rates at the balance sheet date. The effects of foreign currency translation adjustments are included in stockholders' deficit as a component of accumulated other comprehensive loss in the consolidated balance sheets. Related periodic movements in exchange rates are included in other comprehensive income (loss) in the consolidated statements of comprehensive income (loss). Other expense (income), net in the consolidated statements of comprehensive income (loss) includes net foreign exchange transaction losses of $84 and $121 for the years ended December 31, 2019 and 2018, respectively, and $107 and $41 for the three months ended March 31, 2020 and 2019, respectively (unaudited).

        Vertex is taxed as an S-corporation for U.S. federal income tax purposes and for most states. As a result, net income or loss is allocated to the stockholders and is included on their individual income tax returns. In certain states, Vertex is taxed at the corporate level. Accordingly, the income tax provision or benefit is based on taxable income allocated to these states. In certain foreign jurisdictions, Vertex subsidiaries are taxed at the corporate level. Similar to states, the income tax provision or benefit is based on taxable income sourced to these foreign jurisdictions.

        Certain direct and indirect wholly-owned subsidiaries are treated as disregarded entities for U.S. federal income tax purposes and most states under the Internal Revenue Service ("IRS") "check-the-box" regulations. The income and loss from these disregarded entities are reported on the Company's U.S. federal and most state income tax returns in addition to being reported on a foreign jurisdiction tax return if a foreign subsidiary. Other foreign subsidiaries in which we own greater than 50% of the equity by measure of vote or value are treated as controlled foreign companies ("CFCs") for U.S. federal income tax purposes and most states under the IRS foreign tax regulations. The income and loss from these entities is reported on the Company's U.S. federal and some state income tax returns when the foreign earnings are repatriated or deemed to be repatriated to the U.S.

        The Company records deferred income taxes using the liability method. The Company recognizes deferred tax assets and liabilities for future tax consequences of events that have been previously recognized in the Company's consolidated financial statements and tax returns. The measurement of deferred tax assets and liabilities is based on provisions of the enacted tax law. The effects of future changes in tax laws or rates are not anticipated.

        On July 27, 2020, the S corporation election was terminated by the Company's stockholders in connection with the Offering. See Note 12.

        The Company records uncertain tax positions in accordance with ASC 740, Income Taxes, on the basis of a two step process whereby: (i) management determines whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position, and (ii) for those tax positions that meet the more likely than not recognition threshold, management recognizes the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the related tax authority. The impact as a result of the application of ASC 740 is reflected in the consolidated financial statements.

        Total comprehensive income (loss) consists of net income and other comprehensive income (loss). Other comprehensive income (loss) refers to revenues, expenses, gains and losses that under U.S. GAAP are recorded as elements of stockholders' deficit but are excluded from net income. Other comprehensive income (loss) is comprised of foreign currency translation adjustments and revaluations.

        The Company calculates basic and diluted net income per share attributable to common stockholders using the treasury stock method. The Company has Class A voting common stock ("Class A common stock") and Class B non-voting common stock ("Class B common stock") outstanding. Neither class of stock has any liquidity or dividend preferences and are both considered to be participating securities. The diluted net income per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, options to purchase common stock are considered common stock equivalents. Share amounts for all periods presented in these financial statements, including the number of shares that common stock equivalents are convertible into, were retrospectively restated to reflect the three-for-one forward stock split (the "Stock Split") which was effective on July 28, 2020.

1. Summary of significant accounting policies (Continued)

        These financial statements have been prepared in anticipation of the Offering. Effective July 27, the Company converted to and will be taxed as a C corporation for U.S. income tax purposes (see Note 12). Accordingly, a pro forma income tax provision has been disclosed as if the Company was a taxable Corporation for the periods ended December 31, 2019 and March 31, 2020. The Company has computed pro forma entity level income tax expense using an estimated effective tax rate of approximately 25% for the periods ended December 31, 2019 and March 31, 2020, inclusive of all applicable U.S. federal, state, local and foreign income taxes.

        The Company has presented pro forma earnings per share for the year ended December 31, 2019 and the three months ended March 31, 2020. Pro forma basic and diluted income per share for the year ended December 31, 2019 was computed to give effect to the number of shares whose proceeds would be necessary to repay the $50,375 term loan outstanding at December 31, 2019 which was refinanced by the $175,000 term loan entered into by the Company at March 31, 2020 and which is required to be repaid in the event the Offering occurs. Pro forma basic and diluted loss per share for March 31, 2020 was computed to give effect to the number of shares whose proceeds would be necessary to repay the $175,000 term loan that was entered into by the Company at March 31, 2020 and which is required to be repaid in the event the Offering occurs. The pro forma shares for both periods have been computed, assuming the initial public offering price of $19.00 per share, to give effect to the number of shares whose proceeds would be necessary to repay the term loan. The Company has assumed an Offering price of $19.00.

        In addition to the above share adjustments, the determination of pro forma shares outstanding gives effect to the reclassification pursuant to which each share of our common stock outstanding at December 31, 2019 and March 31, 2020 became one share of the new series of Class B common stock. In addition, common stock equivalents that were previously eligible to be exercised for shares of our Class B common stock are now eligible as a result of this reclassification to be exercised for shares of our new series of Class A common stock. This reclassification became effective July 28, 2020. See Note 12.

        Pro forma net income (loss) used to calculate pro forma earnings per share is determined by adjusting net income (loss) for the following: (i) a reduction to interest expense, net of tax effect, assuming repayment of the $50,375 and $175,000 term loans at December 31, 2019 and March 31, 2020, respectively, in connection with the use of the Offering proceeds, and (ii) the pro forma adjustment to income taxes for both periods resulting from the conversion to a C-Corporation effective July 27, 2020. See Note 12.

        As an "emerging growth company," the Jumpstart Our Business Startups Act (the "JOBS Act") allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The Company has elected to delay adoption of certain new or revised accounting standards. As a result, the Company's financial statements may not be comparable to the financial statements of issuers who are required to comply with the effective date for new or revised accounting standards that are applicable to public companies.

        In November 2016, ASU No. 2016-18, Restricted Cash, related to the classification of restricted cash in the cash flow statement was issued. This adds and clarifies guidance on the classification and presentation of changes in restricted cash on the statement of cash flows and to eliminate the diversity in practice related to such classifications. The guidance in ASU No. 2016-18 is required for annual reporting periods beginning after December 15, 2017, for business entities that are public, and after December 15, 2018 for all other entities. The Company adopted this guidance effective January 1, 2019 on a retrospective basis.

        In February 2016, the FASB issued ASU No. 2016-02, Leases. This standard amends several of aspects of lease accounting, including requiring lessees to recognize operating leases with a term greater than one year on their balance sheet as a right-of-use asset, and a corresponding lease liability, measured at the present value of the future minimum lease payments. The standard is effective for

1. Summary of significant accounting policies (Continued)

public entities for fiscal years beginning after December 15, 2018, and after December 15, 2020 for all other companies, with early adoption permitted. The Company intends to adopt this standard effective January 1, 2021 using the modified retrospective transition method and therefore will not restate comparative periods. The Company expects to elect the "package of three" practical expedients permitted under the transition guidance, which allows (i) a carry forward of the historical lease classification conclusions, (ii) management's assessment on whether a contract is or contains a lease, and (iii) the initial direct costs for any leases that exist prior to adoption of the new standard. The Company is currently evaluating the impact this guidance will have on the Company's consolidated financial statements. While the Company has not yet quantified the impact, resulting adjustments are expected to materially increase total assets and total liabilities relative to such amounts reported prior to adoption, but not have a material impact on the consolidated statements of comprehensive income (loss) or consolidated statements of cash flows.

        In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, ("ASU 2016-13") which replaces the existing incurred loss impairment model with an expected credit loss model and requires financial assets, including trade receivables, to be measured at amortized cost to be presented at the net amount expected to be collected. ASU 2016-13 is effective for annual periods, and interim periods within those years, beginning after December 15, 2019, for business entities that are public and meet the definition of an SEC filer (excluding smaller reporting companies), and after December 15, 2022 for all other entities. The Company has elected to delay adoption of this guidance until January 1, 2021. The implementation of ASC 2016-13 is not expected to have a material impact on the Company's financial position.

        In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, ("ASU 2017-04") to eliminate step two of the goodwill impairment test requiring a hypothetical purchase price allocation. Goodwill impairment, if any, is determined by comparing the reporting unit's fair value to its carrying value. An impairment loss is recognized in an amount equal to the excess of the reporting unit's carrying value over its fair value, up to the amount of goodwill allocated to the reporting unit. In addition, income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. ASU 2017-04 is effective for annual periods, and interim periods within those years, beginning after December 15, 2019, for business entities that are public and meet the definition of an SEC filer (excluding smaller reporting companies), and after December 15, 2022 for all other entities. The Company has adopted this guidance effective as of January 1, 2020.

        In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, ("ASU 2017-01") which clarifies when transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation. This new guidance is effective for annual reporting periods beginning after December 15, 2017, for business entities that are public, and after December 15, 2018 for all other entities, with early adoption permitted. The Company adopted this guidance as of January 1, 2019.

1. Summary of significant accounting policies (Continued)

        In December 2019, the FASB issued ASU Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, ("ASU 2019-12") which simplifies the accounting for income taxes. The guidance in ASU 2019-12 is required for annual reporting periods, including interim periods within those annual periods, beginning after December 15, 2020, for business entities that are public, and after December 15, 2021, including interim periods within those annual periods for all other entities, with early adoption permitted. The Company will adopt this guidance on January 1, 2021. The Company is currently evaluating the impact this guidance will have on the Company's consolidated financial statements.

        In December 2019, a novel strain of coronavirus, COVID-19, appeared. The spread of COVID-19 has negatively impacted the global economy and may continue to result in reduced economic activity. This could lead to declines in our customers' revenue, spending and fewer transactions for which transaction tax is due, any of which may result in decreased revenue. However, the extent to which COVID-19 may impact our business will depend on future developments, which are highly uncertain and cannot be predicted.

2. Acquisition (unaudited)

        On January 7, 2020, the Company acquired a 60% controlling interest in Systax, a provider of Brazilian transaction tax content and software. Cash consideration for the purchase was $12,374 and was funded through borrowings under the revolving line of credit (the "Line of Credit"). This acquisition provides the Company with full access to a sizeable database of Brazilian tax content that is critical to supporting its global multi-national customers' business expansion into Brazil. The Company has a contractual purchase commitment to acquire the remaining 40% equity interest from the original Systax Quotaholders incrementally between 2021 through 2024. Future purchase commitment payments for these incremental acquisition amounts are based on a multiple of Systax revenue and earnings before interest, depreciation, amortization and income taxes ("EBITDA") performance at the end of 2020, 2022 and 2023, whereby the Company will have full ownership after the final transaction in 2024. Management has determined these future purchase commitments to be a forward contract, resulting in the Company being required to estimate and record an estimated future purchase commitment amount (the "Purchase Commitment Liability") in connection with recording the initial purchase. The Purchase Commitment Liability is estimated to be $14,344 at the acquisition date based on information currently available. This amount is reflected in future acquisition commitment in the consolidated balance sheet at March 31, 2020, and any adjustments to the acquisition date fair value of this commitment will be adjusted to goodwill during the Measurement Period. Adjustments to the settlement date value that arise as a result of remeasurement at future balance sheet dates will be recorded as interest expense in the consolidated statements of comprehensive income (loss) in the period the change is identified.

        The acquisition was accounted for as a business combination and the total preliminary purchase price was allocated to the net tangible assets acquired and liabilities assumed based on their estimated fair values on the acquisition date, with the excess being recorded as goodwill. The net tangible assets acquired and liabilities assumed were valued at their respective carrying amounts as of the acquisition date pending the receipt of additional information during the Measurement Period. The contractual

value of accounts receivable was $867 at acquisition date. The excess of the purchase consideration over the net tangible assets is recorded as goodwill and primarily reflects the value of the tax content database, the assembled workforce and expected future synergies. Goodwill is deductible for tax purposes. The preliminary values recorded will be adjusted during the Measurement Period as more detailed analyses are performed and further information becomes available regarding the fair values of these amounts as of the acquisition date. Any such adjustments may be material. Subsequent adjustments to these values not associated with determination of their fair values on the acquisition date would be recorded in the consolidated statements of comprehensive income (loss) in the period the change is identified. The following table presents the preliminary purchase price allocation recorded in the Company's consolidated balance sheet as of the acquisition date (unaudited):

        The Company has included the financial results of Systax in the consolidated statement of comprehensive income (loss) from the date of acquisition in accordance with ASC 810 due to the Company having a controlling financial interest in Systax. Systax revenue and net loss for the three months ended March 31, 2020 reflected in the consolidated statement of comprehensive income (loss) were $1,143 and $(256), respectively. As the Systax acquisition did not have a material impact on the Company's reported revenue or net loss for the three months ended March 31, 2020. Accordingly, pro forma financial information has not been presented. The transaction costs associated with the acquisition were approximately $504 and were recorded in general and administrative expense in the year ending December 31, 2019.

        During the year ended December 31, 2018, the Company recorded an impairment of capitalized internal-use software previously utilized to provide cloud-based solutions to customers of $32,692, net of accumulated amortization of $11,907, due to a product strategy shift that resulted in this service no longer being offered to customers after 2018. The software was deemed to be fully impaired due to the net book value of the software exceeding expected future cash flows. This amount is included in impairment of assets in the 2018 consolidated statement of comprehensive income (loss).

        In November 2015, the Company entered into a $105,000 credit agreement (the "Credit Agreement") consisting of a $65,000 term loan (the "Term Loan") and a $40,000 committed Line of Credit. The Company has the option to select an applicable interest rate at either the bank base rate plus an applicable margin (the "Base Rate Option") or the London Interbank Offered Rate ("LIBOR") plus an applicable margin (the "LIBOR Option"). The applicable margins are determined by certain financial covenant performance as defined in the Credit Agreement. At December 31, 2019 and 2018, the Base Rate Option resulted in rates of 4.75% and 5.50%, respectively. At December 31, 2019 and 2018, the LIBOR Option resulted in rates of 2.69% and 3.60%, respectively. The Credit Agreement is collateralized by certain assets of the Company. The Credit Agreement contains financial and operating covenants, which include limitations on the amount of dividends payable in a given period. The Company was in compliance with these covenants at December 31, 2019.

        The Term Loan requires quarterly principal payments over five years, with a balloon payment in November 2020. The interest rate on the Term Loan was 2.69% at December 31, 2019 as the Company selected the LIBOR Option. Term Loan outstanding amounts are reported in current portion of long-term debt and long-term debt, net of current portion, in the consolidated balance sheets. As a result of the Term Loan becoming due in November 2020, the balance outstanding of $50,375 is included in current portion of long-term debt on the consolidated balance sheet at December 31, 2019.

        The Line of Credit expires on November 1, 2020. The Company is required to pay a quarterly fee on the difference between the $40,000 maximum borrowings allowed under the Line of Credit and the unpaid principal balance outstanding under the line at an applicable rate. The applicable rate, determined by certain financial covenant performance as defined in the Credit Agreement, was 0.200%

        On March 31, 2020, the Company entered into a new credit agreement with a bank, which was subsequently amended on April 3, 2020 to permit another bank to be a party to the agreement, consisting of a $175,000 term loan (the "New Term Loan") and a $100,000 committed line of credit (the "New Line of Credit") (collectively, the "New Credit Agreement"). Absent the occurrence of a triggering event, such as an initial public offering which requires immediate repayment of the New Term Loan, the New Term Loan matures in March 2023 and requires quarterly principal payments of $4,375 starting October 1, 2020, with a balloon payment on the payoff date. The Company is required to distribute not less than $110,000 and not more than $125,000 to stockholders within 90 days of the closing date of the New Credit Facility or such amount must be repaid to the lender. The Company has reflected the $110,000 as funds held for distribution to stockholders in the consolidated balance sheet at March 31, 2020. Net proceeds from the New Term Loan after payment of financing fees of $2,904

and repayment of the amounts outstanding under the previous credit agreement of $61,656, were used to fund a portion of the $123,000 distribution made to the stockholders on May 29, 2020. The New Line of Credit matures in March 2025 and had no outstanding borrowings at closing. The Company has the option to select an applicable interest rate at either the bank base rate plus an applicable margin (the "New Base Rate Option") or the LIBOR plus an applicable margin (the "New LIBOR Option"). The applicable margins are determined by certain financial covenant performance as defined in the New Credit Agreement. At March 31, 2020 and May 31, 2020, the New Base Rate Option and New LIBOR Option were 3.75% and 2.50%, respectively. The New Credit Agreement is collateralized by certain assets of the Company. The New Credit Agreement contains financial and operating covenants.

6. Options for redeemable shares

        Prior to 2006, Vertex issued stock options under separate option agreements, not subject to an option plan, permitting certain key members of management and the Board to purchase shares of Class B common stock. At December 31, 2019, 3,849 shares of Class B common stock were reserved for issuance under these option agreements. The exercise price of the shares under these option agreements is equal to the fair value of the shares as of the grant date, as determined by the Board with assistance from management and an independent third-party valuation provider. All options are fully vested at December 31, 2019.

        The options are exercisable upon: (i) any time after the option holder is no longer an employee of the Company or a member of the Board; (ii) the Grantee's death or disability; (iii) the occurrence of a Partial Triggering Event (as defined below); or (iv) the occurrence of a Triggering Event (as defined below). In addition, the option agreements provide employee option holders with the ability to exercise a portion of their options between April 15 and April 30 of each year based upon the fair value of the Class B common stock as of December 31 of the prior calendar year, provided that certain Company performance is achieved. At the election of the Company, the option agreements allow option holders to satisfy tax withholding obligations incurred in connection with the exercise by exchanging exercised options in lieu of payment of income taxes paid by the Company on their behalf. The fair value of exchanged exercised options is recorded as a reduction to stockholders' deficit as part of the exercise of the related options, net of cash received.

        Since these option agreements permit the option holders to put their exercised shares back to the Company for a price per share based upon the fair value of the Class B common stock determined six months after the holder exercised the options, they are classified as temporary equity and included in options for redeemable shares on the consolidated balance sheets. In addition, these option agreements permit the Company to call the shares based upon the fair value of the Class B common stock determined six months after the options were exercised. The Company has never exercised its right to call any shares issued from option exercises. In the event of the sale of at least 50% of the Company's stock or all the assets of the Company ("Triggering Event") in a single or multiple transactions, the option holders have the right to exercise their options and sell their related shares in connection with the transactions. Unexercised options expire after a Triggering Event. In the event of a sale of at least 25% of the Company's assets to an unrelated third-party in a single or multiple transactions ("Partial

Triggering Event"), the option holders have the right to exercise a portion of their options pro rata based on the sales price and sell their related shares in connection with the transaction. Unexercised options remaining after a Partial Triggering Event remain outstanding. In addition, in the event stockholders owning at least 51% of the outstanding stock of the Company (the "selling stockholders") sell a portion of their stock to an unrelated third-party, the option holders have the right to exercise and sell an amount of options in the same proportion as the selling stockholders (a "tag-along right"). The option holders may also be required to exercise all their outstanding options and sell all related shares in the event the selling stockholders sell at least 51% of their ownership to an unrelated third-party (a "drag-along right").

7. Stockholders' deficit

        There are no dividend or liquidation preference differences between the Class A or Class B common stock.

        In April 2019, Vertex issued 225 shares of Class B common stock in connection with the exercise of stock options by option holders for cash of $68, net of 51 shares that were immediately returned to Vertex upon exercise in lieu of payment of income taxes payable by the option holders of $184. Vertex repurchased the 225 shares of Class B common stock in October 2019 at the request of the option holders for cash of $841.

        In April 2018, Vertex issued 402 shares of Class B common stock in connection with the exercise of stock options by option holders for cash of $177, net of 66 shares that were immediately returned to Vertex upon exercise in lieu of payment of income taxes payable by the option holders of $209. Vertex repurchased the 402 shares of Class B common stock in October 2018 at the request of the option holders for cash of $1,277.

7. Stockholders' deficit (Continued)

        At December 31, 2019 and 2018, repurchased shares ("Treasury Stock") aggregating 41,910 and 41,685, respectively, are carried at cost and included in Treasury Stock in the consolidated balance sheets. Treasury Stock includes 41,757 and 41,532 shares of Class B common stock at December 31, 2019 and 2018, respectively, and 153 shares of Class A common stock for both years.

        The Board declared aggregate distributions to stockholders of the Class A and Class B common stock of $13,183 and $10,892 in December 2019 and 2018, respectively, to be paid pro rata to stockholders in January 2020 and 2019, respectively. Such amounts are reflected in distributions payable on the consolidated balance sheets. Payment of distributions to stockholders is limited by certain debt covenants.

        The Board declared and paid aggregate distributions pro rata to stockholders of the Class A and Class B common stock of $4,010 during the three months ended March 31, 2020 (unaudited). In May 2020 the Board declared and paid aggregate distributions pro rata to stockholders of the Class A and Class B common stock of $123,000 (unaudited).

8. Employee benefit and deferred compensation plans

        The Company maintains a 401(k) plan that covers eligible employees subject to certain age and length of service requirements. The Company matches up to 3% of eligible compensation during the period in which an eligible participant contributes to the plan. Matching contributions were $3,419 and $2,893 for the years ended December 31, 2019 and 2018, respectively, and $1,125 and $1,150 for the three months ended March 31, 2020 and 2019, respectively (unaudited). In addition, a discretionary profit-sharing contribution of 3% of eligible compensation for eligible employees was approved and aggregated $3,363 and $2,886 for the years ended December 31, 2019 and 2018, respectively, and is reflected in accrued salaries and benefits in the consolidated balance sheets.

        The Company has a long-term rewards ("LTR") plan for certain key employees which provides for compensation related to growth in certain financial measures over a three-year period (the "Reward Performance Period"), subject to achieving an annual minimum net income target (the "Net Income Target") during each year of the Reward Performance Period. Each year, eligible LTR plan participants receive an individual target award opportunity ("Award Opportunity") for a new three-year Reward Performance Period (i.e. target award grant made in 2018 is for years 2018 through 2020). For Reward Performance Periods prior to 2018, compensation earned for growth in the financial measures over each Reward Performance Period is paid in cash in the year following the end of the respective Reward Performance Period, assuming the Net Income Target was achieved for each year of the respective Reward Performance Period. Starting in 2018, the Net Income Target is only required to be achieved in the final year of the Reward Performance Period. Estimated compensation is recorded during each year of a Reward Performance Period ("accrued LTR Award Opportunities").

8. Employee benefit and deferred compensation plans (Continued)

        Compensation expense of $2,462 and $2,012 was recorded in the consolidated statements of comprehensive income (loss) for accrued LTR Award Opportunities for the years ended December 31, 2019 and 2018, respectively, and $798 and $492 for the three months ended March 31, 2020 and 2019, respectively (unaudited), for open Reward Performance Periods. The Net Income Target was not achieved in 2018, which would have resulted in the LTR Award Opportunities being zero for the three-year Reward Performance Periods that started in 2016 and 2017. The Board waived the 2018 Net Income Target requirement for these Reward Performance Periods. Amounts to be paid to participants in 2020 for the Reward Performance Period starting in 2017 of $2,717, and amounts paid in 2019 for the Reward Performance Period that started in 2017 are reflected in deferred compensation, current in the consolidated balance sheets as of December 31, 2019 and 2018, respectively. The remaining balances of accrued LTR Award Opportunities for open Reward Performance Periods of $1,812 and $2,085 at December 31, 2019 and 2018, respectively, and $2,610 as of March 31, 2020 (unaudited) are reflected in deferred compensation, net of current portion, in the consolidated balance sheets.

        The Company has a SAR plan for the purpose of providing incentives to key members of management to contribute to the growth and financial success of the Company. SAR plan awards ("SAR Awards") are represented as a fixed number of shares of Class B common stock ("SAR Units"). SAR Units outstanding aggregated 12,276 and 10,671 at December 31, 2019 and 2018, respectively, and 12,153 at March 31, 2020 (unaudited). SAR Units are issued at the equivalent of the fair value of the equivalent number of shares of the Company's Class B common stock on the grant date ("Base Value"), as determined by the Board with assistance from management and an independent third-party valuation provider, and compensation is based upon the appreciation of the SAR Units in excess of the Base Value over the service vesting period. SAR Awards are exercisable upon 50% vesting or upon the occurrence of a triggering event.

        Vested SAR units are redeemed upon the occurrence of a triggering event. Triggering events include: (i) expiration of the term of the SAR; (ii) a change of control of the Company whereby stockholders holding at least 50% of the voting stock of the company sell their shares; (iii) a merger of the Company with an unrelated third-party; (iv) an initial public offering; and (v) death, disability or retirement of a SAR participant.

        SAR participants are limited to exercising no more than 25% of their vested SAR Units in any given year. SAR Awards generally vest 50% and 100% after two years and five years, respectively, from the grant date, or as determined by the Board. Maximum contractual terms range from ten years to term of employment of the participant. SAR Awards are settled in cash only, not through the issuance of shares. SAR Award exercises are limited each year to the proportion of the vested SAR units to the total units outstanding multiplied by adjusted net cash from operating activities (the "Liquidity Pool"), which is defined as cash from operating activities less cash paid for property and equipment and capitalized software for a given period.

        The weighted average grant date intrinsic value of the SARs on grant date is zero as the Company's Board grants all awards at a price per share not less than the per share fair value of the Company's Class B common stock underlying such awards on the date of grant.

        During the years ended December 31, 2019 and 2018, $9,460 and $5,108, respectively, and the three months ended March 31, 2020 and 2019, $34,920 and $1,310, respectively (unaudited), was recorded as compensation expense in the consolidated statements of comprehensive income (loss) to reflect the appreciation in value of the vested portion of outstanding SAR Awards over the Base Value from the grant date. SAR Awards totaling $1,229 and $1,825 were exercised during 2019 and 2018, respectively, and $2,391 during the three months ended March 31, 2020 (unaudited). Accrued SAR Awards of $5,790 and $3,979 at December 31, 2019 and 2018, respectively, and $5,790 at March 31, 2020 (unaudited), representing SAR Units scheduled for redemption and 25% of the vested SAR Units eligible for exercise in 2020 and 2019, respectively, are reflected in deferred compensation in the consolidated balance sheets. The remaining balances of accrued SAR Awards of $16,506 and $10,086 at December 31, 2019 and 2018, respectively, and $49,035 at March 31, 2020 (unaudited) are reflected as deferred compensation, net of current portion, in the consolidated balance sheets. We had approximately $3,900 and $16,772 of total unrecognized compensation expense for unvested SAR Awards at December 31, 2019 and March 31, 2020 (unaudited), respectively, which we expect to recognize over a period of approximately one to five years.

        The SAR Awards were amended in connection with the Offering. See Note 12.

        At December 31, 2019, the Company has available foreign operating losses of approximately $1,169, some of which expire as early as 2025, and others which carry forward indefinitely. In addition, the Company has $54 of foreign non-operating losses, which carryforward indefinitely. A valuation allowance for a portion of the foreign operating and all of the foreign non-operating losses are recorded at December 31, 2019 and 2018.

        At December 31, 2019, the Company has available U.S. state operating loss carry forwards of $1,255 which expire through 2026. Management expects to fully utilize these state operating loss carry forwards.

        The Company files tax returns as prescribed by the tax laws of the jurisdictions in which the Company operates. Under applicable U.S. federal statutes, tax years ended December 31, 2016 through December 31, 2019 remain subject to examination. Under applicable statutes, state and foreign corporate tax returns filed for the Company and its respective foreign subsidiaries for years ended December 31, 2014 through December 31, 2019 remain subject to examination by the respective authorities.

        The Company used an annual effective tax rate approach to calculate income taxes for the three months ended March 31, 2020 and 2019. The annual effective tax rate differs from the U.S. federal statutory rate due primarily to state tax expense in states that do not recognize the federal S corporation election but instead tax the Company at the corporate level. Income taxes for international operations are not material for the three months ended March 31, 2020 and 2019 (unaudited).

11. Income taxes (Continued)

        The effective income tax rate was an expense of (0.9%) and 2.7% for the three months ended March 31, 2020 and 2019, respectively (unaudited). The difference is due primarily to a pretax loss for the three months ended March 31, 2020 from an increase in deferred compensation costs during the quarter.

        Effective July 27, 2020, the Company converted to and will be taxed as a C Corporation for U.S. income tax purposes (see Note 12).

12. Subsequent Events

        On July 27, 2020, the Company and its shareholders entered into an S corporation and Tax Sharing Agreement, pursuant to which the Company's S corporation status for U.S. federal income tax purposes was terminated on July 27, 2020 and the Company will thereafter be taxed as C Corporation. As a result, the Company's effective tax rate is projected to increase from approximately 2.5% to 25%. Management anticipates recording a deferred tax benefit at the effective date of the conversion of approximately $34,000 (unaudited) due to the increased tax rate.

        On July 28, 2020, the Company filed its amended and restated certificate of incorporation with the Delaware Secretary of State to effect the Stock Split, a share exchange and to establish a new capital structure for the Company. The Stock Split resulted in each one share owned by a stockholder being exchanged for three shares of common stock, and the number of shares of the Company's common stock issued and outstanding was increased proportionately based on the Stock Split. In addition, in connection with the Stock Split, stockholders of record exchanged their existing Class A voting and Class B non-voting common stock for newly created shares of Class A common stock ("Class A") and Class B common stock ("Class B") issued in connection with the new capital structure. The effect of the Stock Split was recognized retrospectively in the Consolidated Financial Statements.

        In connection with the new capital structure, the Company authorized 450,000 shares of common stock, par value $0.001 per share, and 30,000 shares of preferred stock, par value $0.001 per share. Common stock is divided into two classes, Class A with one vote per share, and Class B with ten votes per share. The rights of the holders of Class A and Class B are identical, except with respect to voting, conversion and transfer rights. Following the Offering, authorized Class A will consist of 300,000 shares and authorized Class B will consist of 150,000 shares.

        Each outstanding share of Class B is convertible at any time at the option of the holder into one share of Class A. Each share of Class B will convert automatically into one share of Class A upon any transfer, except for certain permitted transfers to other Class B stockholders or other members of the control group. Each share of Class B will convert automatically into one share of Class A if the voting power of all then-outstanding shares of Class B comes to represent less than ten percent of the combined voting power of all shares of the then-outstanding common stock. Once converted or transferred and converted into Class A, the Class B may not be reissued.

        The Board is authorized to issue up to 30,000 shares of preferred stock in one or more series without stockholder approval. The Board of directors has the discretion to determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock. Upon closing of the Offering, there will be no shares of preferred stock outstanding.

        SAR participants were offered the option to either redeem their SARs upon the occurrence of the Offering or amend their SARs pursuant to which, upon effectiveness of the Company's 2020 Incentive Award Plan (the "2020 Plan") to occur concurrent or shortly after the effective date of the Offering, such SARs will become options to purchase shares of new Class A common stock under the 2020 Plan. Effective July 13, 2020, this offer period ended and all SAR participants eligible to receive the offer accepted and will have their outstanding SARs converted to stock options with equivalent terms under the 2020 Plan (the "Converted SARs"). This is considered a modification of these SAR awards.

        Converted SARs with either no expiration date or that expire during calendar year 2020 will convert to options and be automatically exercised into shares (the "Auto Exercise New Options"). Shares issued in connection with the Auto Exercise New Options will be net of the number of shares of common stock necessary to satisfy the aggregate exercise price and the tax withholding obligation of such options. The Auto Exercise New Option participants also had the ability to require the Company to repurchase all or a portion of the shares remaining after this reduction on the Offering date for cash based on the Offering price.

        Management continues to record changes in the intrinsic value of the SARs in 2020 up to the date on which the Company is considered to have become a public entity. Management will record the change in accounting policy based on the application of ASC 718. The Company will record any incremental increase in fair value of the Converted SARs resulting from the modification as compensation expense at the time of the exchange, which is contingent upon the occurrence of the Offering. Upon modification, the Converted SARs will no longer be recorded as a liability under ASC 718 and the accumulated liability balance will be reclassified to stockholders equity. The unvested portion of the Converted SAR liability at the Offering date will be amortized over the remaining service period of the Converted SARs as compensation expense. At the Offering price of $19.00 management estimates the fair value of the Converted SARs at the Offering date to be approximately $197,000 (unaudited), of which approximately $153,000 (unaudited) will be vested. At this value, management would record estimated additional compensation expense of approximately $98,000 (unaudited) for vested Converted SARs from April 1 to the Offering date, including the impact of the change in accounting. The remaining approximate $44,000 (unaudited) of unvested Converted SAR liability will be recognized as compensation expense over the remaining service period through 2025, including the impact of the change in accounting.
