QUESTIONS AND ANSWERS ABOUT THE 2022 ANNUAL MEETING OF STOCKHOLDERS

​

WHO IS ENTITLED TO VOTE AT THE ANNUAL MEETING?

​

The Record Date for the Annual Meeting is April 18, 2022. You are entitled to vote at the Annual Meeting only if you were a stockholder of record at the close of business on that date, or if you hold a valid proxy for the Annual Meeting. You will need to obtain your own Internet access if you choose to attend the Annual Meeting and/or vote over the Internet. Each share of our Class A common stock entitles its holders to one vote per share on all matters presented to our stockholders at the Annual Meeting. Each share of our Class B common stock entitles its holders to 10 votes on all matters presented to a vote of our stockholders at the Annual Meeting.

WHAT IS THE DIFFERENCE BETWEEN BEING A "RECORD HOLDER" AND HOLDING SHARES IN "STREET NAME"?

​

A record holder holds shares in his or her name. Shares held in "street name" means shares that are held in the name of a bank or broker on a person’s behalf.

AM I ENTITLED TO VOTE IF MY SHARES ARE HELD IN "STREET NAME"?

​

Yes. If your shares are held by a bank or a broker, you are considered the "beneficial owner" of those shares held in "street name." If your shares are held in street name, our proxy materials are being provided to you by your bank or broker, along with a voting instruction card if you received printed copies of our proxy materials. As the beneficial owner, you have the right to direct your bank or broker how to vote your shares, and the bank or broker is required to vote your shares in accordance with your instructions. If you haven’t received information on how to attend the Annual Meeting, you should contact your bank or broker to obtain your control number or otherwise vote through the bank or broker.

HOW MANY SHARES MUST BE PRESENT TO HOLD THE ANNUAL MEETING?

​

A quorum must be present at the Annual Meeting for any business to be conducted. The presence at the Annual Meeting, present electronically or represented by proxy, of the holders of a majority in voting power of Common Stock issued and outstanding and entitled to vote on the Record Date will constitute a quorum.

WHO CAN ATTEND THE 2022 ANNUAL MEETING OF STOCKHOLDERS?

The Annual Meeting will be held entirely online to allow greater participation. In order to attend the Annual Meeting, you must register at www.proxydocs.com/VERX. Upon completing your registration, you will receive further instructions via email, including a unique link that will allow you access to the Annual Meeting and to vote and submit questions during the Annual Meeting. As part of the registration process, you must enter the control number located on your proxy card, voting instruction form, or Notice of Internet Availability. If you are a beneficial owner of shares registered in the name of a broker, bank or other nominee, you will also need to provide the registered name on your account and the name of your broker, bank or other nominee as part of the registration process.

WHY A VIRTUAL MEETING?

​

We are excited to embrace the latest technology to provide expanded access, improved communication and cost savings for us and our stockholders. We believe the virtual meeting will enable increased stockholder attendance and participation since stockholders can participate from any location around the world. Furthermore, as part of our effort to maintain a safe and healthy environment for our directors, members of management and stockholders who wish to attend the Annual Meeting, in light of the ongoing concerns regarding the COVID-19 pandemic, we believe that hosting a virtual meeting is in the best interests of the Company and such attendees of the Annual Meeting.

WHAT IF DURING THE CHECK-IN TIME OR DURING THE ANNUAL MEETING I HAVE TECHNICAL DIFFICULTIES OR TROUBLE ACCESSING THE VIRTUAL MEETING WEBSITE?

​

We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual meeting website.

WHAT IF A QUORUM IS NOT PRESENT AT THE ANNUAL MEETING?

​

If a quorum is not present at the scheduled time of the Annual Meeting, then either (i) the chairperson of the Annual Meeting or (ii) a majority in voting power of the stockholders entitled to vote at the Annual Meeting, present electronically or represented by proxy, may adjourn the Annual Meeting until a quorum is present or represented.

WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE INTERNET NOTICE OR MORE THAN ONE SET OF PROXY MATERIALS?

​

It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each Internet Notice or set of proxy materials, please submit your proxy by phone, via the Internet, or, if you received printed copies of the proxy materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope.

HOW DO I VOTE?

Upon completing your registration, you will receive further instructions via email, including a unique link that will allow you access to the Annual Meeting and to vote and submit questions during the Annual Meeting.

The Annual Meeting webcast will begin promptly at 9:00 a.m. Eastern Time, on June 14, 2022.

If your shares are held in street name through a bank or broker, you will receive instructions on how to vote from the bank or broker. You must follow their instructions in order for your shares to be voted. Internet and telephone voting also may be offered to stockholders owning shares through certain banks and brokers. If your shares are not registered in your own name and you would like to vote your shares at the Annual Meeting, you may register to participate and enter the appropriate password included in the voting instruction card provided to you by your bank or broker. If you hold your shares in street name and you do not receive an appropriate password, you may need to log in to your bank or broker’s website and select the shareholder communications mailbox to access the Annual Meeting and vote. Instructions should also be provided on the voting instruction card provided by your bank or broker.

CAN I CHANGE MY VOTE AFTER I SUBMIT MY PROXY?

​

Yes.

If you are a registered stockholder, you may revoke your proxy and change your vote:

Your most recent proxy card or Internet or telephone proxy is the one that is counted. Your virtual attendance at the Annual Meeting by itself will not revoke your proxy unless you give written notice of revocation to the Secretary before your proxy is voted or you vote electronically during the Annual Meeting.

If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by your bank or broker, or you may vote electronically during the Annual Meeting.

WHO WILL COUNT THE VOTES?

​

A representative of Equiniti, our inspector of election, will tabulate and certify the votes.

WHAT IF I DO NOT SPECIFY HOW MY SHARES ARE TO BE VOTED?

​

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board. The Board’s recommendations are indicated on page 2 of this proxy statement, as well as with the description of each proposal in this proxy statement.

WILL ANY OTHER BUSINESS BE CONDUCTED AT THE ANNUAL MEETING?

​

We know of no other business that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting, however, the proxy holders named on the Company’s proxy card will vote your shares in accordance with their best judgment.

HOW MANY VOTES ARE REQUIRED FOR THE APPROVAL OF THE PROPOSALS TO BE VOTED UPON AND HOW WILL ABSTENTIONS AND BROKER NON-VOTES BE TREATED?

​

​

WHAT IS AN ABSTENTION AND HOW WILL VOTES WITHHELD AND ABSTENTIONS BE TREATED?

​

A "vote withheld," in the case of the proposal regarding the election of directors, or an "abstention," in the case of the proposal regarding the ratification of our independent registered accounting firm, represents a stockholder’s affirmative choice to decline to vote on a proposal. Votes withheld and abstentions are counted as present and entitled to vote for purposes of determining a quorum. Votes withheld have no effect on the election of directors. Abstentions have no effect on the ratification of the appointment of Crowe LLP.

WHAT ARE BROKER NON-VOTES AND DO THEY COUNT FOR DETERMINING A QUORUM?

​

Generally, broker non-votes occur when shares held by a broker in "street name" for a beneficial owner are not voted with respect to a particular proposal because the broker (i) has not received voting instructions from the beneficial owner and (ii) lacks discretionary voting power to vote those shares. A broker is entitled to vote shares held for a beneficial owner on routine matters, such as the ratification of the appointment of Crowe LLP as our independent registered public accounting firm, without instructions from the beneficial owner of those shares. On the other hand, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on non-routine matters, such as the election of directors. Broker non-votes count for purposes of determining whether a quorum is present.

WHERE CAN I FIND THE VOTING RESULTS OF THE 2022 ANNUAL MEETING OF STOCKHOLDERS?

​

We plan to announce preliminary voting results at the Annual Meeting and we will report the final results in a Current Report on Form 8-K, which we intend to file with the SEC shortly after the Annual Meeting.

PROPOSALS TO BE VOTED ON

​

PROPOSAL 1: Election of Directors

​

Our Board, after consultation with the Nominating and Corporate Governance Committees, has nominated J. Richard Stamm and Philip Saunders as Class II Director nominees to be elected to hold office until the Annual Meeting of Stockholders to be held in 2025 and until such director’s successor is elected and qualified or until such director’s earlier death, resignation or removal.

We currently have eight directors on our Board. The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the two nominees receiving the highest number of affirmative “FOR” votes will be elected as Class II Directors. Votes withheld and broker non-votes will have no effect on the outcome of the vote on this proposal.

Our Board currently consists of eight members, which includes one employee director, our President and Chief Executive Officer, David DeStefano. Our Amended and Restated Certificate of Incorporation (“Charter”) and Amended and Restated Bylaws (“Bylaws”) provide that the authorized number of directors shall be fixed from time to time by a resolution of the majority of our Board. Our current non-employee directors are:

​

Terrence Kyle will be retiring from the Board in June 2022 and Philip Saunders is standing for election at the Annual Meeting described below in this Proposal 1.

Our Board are 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 2022 for the Class II Directors, 2023 for the Class III Directors and 2024 for the Class I 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 into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control.

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote the shares of Common Stock represented by the proxy for the election as Class II Directors the persons whose names and biographies appear below. All of the persons whose names and biographies appear below are currently serving as our directors. In the event any of the nominees should become unable to serve or for good cause will not serve as a director, it is intended that votes will be cast for a substitute nominee designated by the Board or the Board may elect to reduce its size. The Board has no reason to believe that the nominees named below will be unable to serve if elected. Each of the nominees has consented to being named in this proxy statement and to serve if elected.

On April 19, 2022, our Audit Committee approved the engagement of Crowe LLP as the Company’s Independent Auditor to serve as our Independent Auditor for the fiscal year ended December 31, 2022. Neither Crowe LLP nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit related services. A representative of Crowe LLP is expected to attend the Annual Meeting, have an opportunity to make a statement if he or she desires to do so, and be available to respond to appropriate questions from stockholders.

In the event that the appointment of Crowe LLP is not ratified by the stockholders, the Audit Committee will consider this fact when it appoints the Independent Auditors for the fiscal year ending December 31, 2023. Even if the appointment of Crowe LLP is ratified, the Audit Committee retains the discretion to appoint a different Independent Auditor at any time if it determines that such a change is in the interests of Vertex.

VOTE REQUIRED

​

This proposal requires the approval of the affirmative vote of the holders of a majority in voting power of the votes cast. Abstentions will have no effect on the proposal. Because brokers have discretionary authority to vote on the ratification of the appointment of Crowe LLP, we do not expect any broker non-votes in connection with this proposal.

RECOMMENDATION OF THE BOARD

​

​

Report of the Audit Committee of the Board of Directors

​

The Audit Committee has evaluated Vertex’s audited financial statements for the fiscal year ended December 31, 2021 and has discussed these financial statements with management and Vertex’s Independent Auditor. The Audit Committee also discussed with the independent registered public accountants the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The Audit Committee also received written disclosures and the letter from the independent registered public accountants required by applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee concerning independence, and the Audit Committee discussed with the Independent Auditor the accountant’s independence.

Based on its discussions with management and the Independent Auditor, and its review of the representations and information provided by management and the Independent Auditor, the Audit Committee recommended to the Board that the audited financial statements be included in Vertex’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

Board of Directors

​

CORPORATE GOVERNANCE

​

GENERAL

​

Our Board has adopted Corporate Governance Guidelines, a Code of Ethics and Conduct and charters for our Nominating and Corporate Governance Committee, Audit Committee and Human Capital Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of Vertex. You can access our current committee charters, our Corporate Governance Guidelines and our Code of Ethics and Conduct via our website at http://ir.vertexinc.com or by writing to our Secretary at our offices at 2301 Renaissance Blvd., King of Prussia, PA 19406.

FAMILY RELATIONSHIPS

Ms. Radcliffe and Ms. Thompson are siblings. There are no other family relationships among any of our executive officers or directors.

Table of Contents

STOCKHOLDERS’ AGREEMENT

In connection with our IPO in July 2020, we entered into the Stockholders’ Agreement with Amanda Westphal Radcliffe, Stefanie Westphal Thompson and Jeffrey Westphal, with Ms. Radcliffe and Ms. Thompson each serving as a member of our Board, and their affiliated trust entities and family members.  For so long as Ms. Radcliffe, Ms. Thompson or Mr. 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, 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. 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 Common 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.

DIRECTOR INDEPENDENCE

Our Board has undertaken a review of its composition, the composition of its committees and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board has determined that Eric Andersen, Bradley Gayton, Terrence Kyle, Kevin Robert, and J. Richard Stamm, representing five 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 (“Nasdaq”). In addition, the director candidate, Philip Saunders, does not have any relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that he 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. In making this determination, our Board considered the current and prior relationships that each non-employee director has with our Company and all other facts and circumstances our Board deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director.

​

CONTROLLED COMPANY EXEMPTION

​

The parties to the Stockholders’ Agreement have more than 50% of the voting power for the election of directors, and, as a result, we are considered a "controlled company" for the purposes of the Nasdaq listing requirements. As such, we qualify for, and rely on, exemptions from certain corporate governance requirements. As a result, we are not subject to certain corporate governance requirements, including that a majority of our Board consists of "independent directors”, as defined under the Nasdaq rules. In addition, we are not required to have a Nominating and Corporate Governance Committee or Human Capital Committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities or to conduct annual performance evaluations of the Nominating and Corporate Governance and Human Capital Committees. We currently rely on the exemption from the requirement to have a Nominating and Corporate Governance Committee composed entirely of independent directors, and in the future we may elect to continue to rely on such exemption and/or other available exemptions. Accordingly, our stockholders may not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of the Nasdaq.

​

If at any time we cease to be a "controlled company" under the rules of Nasdaq, our Board intends to take all action necessary to comply with the Nasdaq corporate governance rules.

​

DIRECTOR CANDIDATES

​

The Nominating and Corporate Governance Committee is responsible for identifying and reviewing the qualifications of potential director candidates and recommending to the Board those candidates to be nominated for election to the Board, subject to any obligations and procedures governing the nomination of directors to the Board that may be included in the Stockholders’ Agreement and any other stockholders’ agreement to which we are a party.

13

Table of Contents

​

To facilitate the search process for director candidates, the Nominating and Corporate Governance Committee may solicit our current directors and executives for the names of potentially qualified candidates or may ask directors and executives to pursue their own business contacts for the names of potentially qualified candidates. The Nominating and Corporate Governance Committee may also consult with outside advisors or retain search firms to assist in the search for qualified candidates or consider director candidates recommended by our stockholders. Once potential candidates are identified, the Nominating and Corporate Governance Committee reviews the backgrounds of those candidates, evaluates candidates’ independence from us and potential conflicts of interest, and determines if candidates meet the qualifications desired by the Nominating and Corporate Governance Committee of candidates for election as director.

​

In accordance with our Corporate Governance Guidelines, in evaluating the suitability of individual candidates, the Nominating and Corporate Governance Committee will consider (i) minimum individual qualifications, including a high level of personal and professional integrity, strong ethics and values and the ability to make mature business judgments and all other factors it considers appropriate, which may include experience in corporate management, experience as a board member of other public companies, relevant professional or academic experience, leadership skills, financial and accounting background, executive compensation background and whether the candidate has the time required to fully participate as a director of the Company. Our Corporate Governance Guidelines provide that the Board should monitor the mix of specific experience, qualifications and skills of its directors in order to assure that the Board, as a whole, has the necessary tools to perform its oversight function effectively in light of the Company’s business and structure. Our Nominating and Corporate Governance Committee has a formal policy with respect to diversity and believes that our Board, taken as a whole, should embody diverse skills, experiences, backgrounds, races and genders.

​

​

Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration as potential director candidates by submitting the names of the recommended individuals, together with appropriate biographical information and background materials, to the Nominating and Corporate Governance Committee, c/o Secretary, Vertex, Inc., 2301 Renaissance Blvd., King of Prussia, PA 19406. In the event there is a vacancy, and assuming that appropriate biographical and background material has been provided on a timely basis, the Nominating and Corporate Governance Committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others.

​

COMMUNICATIONS FROM INTERESTED PARTIES

​

Anyone who would like to communicate with, or otherwise make his or her concerns known directly to the Board, the chairperson of any of the Audit, Nominating and Corporate Governance, and Human Capital Committees, or to the

independent directors as a group, may do so by addressing such communications or concerns to the Secretary of the Company, 2301 Renaissance Blvd., King of Prussia, PA 19406, who will forward such communications to the appropriate party. Such communications may be done confidentially or anonymously.

BOARD LEADERSHIP STRUCTURE AND ROLE IN RISK OVERSIGHT

​

Our Board exercises its discretion in combining or separating the roles of Chairman of the Board and Chief Executive Officer as it deems appropriate in light of prevailing circumstances. We believe that we, like many U.S. companies, are well-served by a flexible leadership structure. Currently, the roles are combined, with Mr. DeStefano serving as Chairman of the Board and Chief Executive Officer. Our Board has determined that combining the roles of Chairman of the Board and Chief Executive Officer is best for our Company and its stockholders at this time because it promotes unified leadership by Mr. DeStefano and allows for a single, clear focus for management to execute the Company’s strategy and business plans. Our Board is comprised of individuals with extensive experience in finance, the technology industry and public company management. For these reasons and because of the strong leadership of Mr. DeStefano as Chairman of the Board and Chief Executive Officer, our Board has concluded that our current leadership structure is appropriate at this time. However, our Board will continue to consider whether the positions of Chairman of the Board and Chief Executive Officer should be separated or combined at any given time as part of our succession planning process.

Our Corporate Governance Guidelines provide that, if the Chairman of the Board is also our Chief Executive Officer or is a director that does not otherwise qualify as an independent director, the independent directors may elect a lead director whose responsibilities include presiding over all meetings of the Board at which the Chairman is not present, including any executive sessions of the non-management directors; approving meeting schedules and agendas; and acting as the liaison between the independent directors and the Chairman of the Board, as appropriate. The full list of responsibilities of our lead director may be found in our Corporate Governance Guidelines. Our current lead director is Eric Andersen.

Risk assessment and oversight are an integral part of our governance and management processes. Our management is responsible for our day-to-day risk management activities. Our Board oversees the implementation of risk mitigation strategies by management and encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks we face, including cybersecurity risks. Throughout the year, senior management reviews these risks with the Board at regular board meetings as part of management presentations that focus on particular business functions, operations or strategies, and presents the steps taken by management to mitigate or eliminate such risks. Our Board is apprised of particular risk management matters in connection with its general oversight and approval of corporate matters and significant transactions. Our Board administers this oversight function, including the oversight of cybersecurity risks, directly through the Board as a whole, as well as through various standing committees of the Board that address risks inherent in their respective areas of oversight. The Board does not believe that its role in the oversight of our risks affects the Board’s leadership structure.

ANTI-HEDGING POLICY

​

Our Board has adopted an Insider Trading Compliance Policy, which applies to all of our directors, officers and employees. The policy prohibits our directors, officers and employees and any entities they control from engaging in any hedging or monetization transactions, such as zero-cost collars and forward sale contracts, involving the Company’s equity securities.

CODE OF ETHICS AND CONDUCT

​

Our Board has adopted a Code of Ethics and Conduct that contain the ethical principles by which our chief executive officer and chief financial officer, among others, are expected to conduct themselves when carrying out their duties and responsibilities. A copy of our Code of Ethics and Conduct is available on our website at http://ir.vertexinc.com. We will provide a copy of our Code of Ethics and Conduct to any person, without charge, upon request, by writing to, Vertex, Inc., 2301 Renaissance Blvd., King of Prussia, PA 19406 Attn: Legal (telephone number (800) 355-3500). We intend to satisfy the disclosure requirement under Item 5.05 of Form 8-K regarding an amendment to, or waiver from, a provision of our Code of Ethics and Conduct by posting such information on our website at www.vertexinc.com.

ATTENDANCE BY MEMBERS OF THE BOARD AT MEETINGS

​

There were six meetings of the Board during the fiscal year ended December 31, 2021. During the fiscal year ended December 31, 2021, each director attended at least 80% of the aggregate of (i) all meetings of the Board and (ii) all meetings of the committees on which the director served during the period in which he or she served as a director.

Under our Corporate Governance Guidelines, which are available on our website at http://ir.vertexinc.com, a director is expected to spend the time and effort necessary to properly discharge his or her responsibilities. Accordingly, a director is expected to regularly prepare for and attend meetings of the Board and all committees on which the director sits (including separate meetings of the independent directors), with the understanding that, on occasion, a director may be unable to attend a meeting. A director who is unable to attend a meeting of the Board or a committee of the Board is expected to notify the Chairman of the Board or the Chairman of the appropriate committee in advance of such meeting, and, whenever possible, participate in such meeting via teleconference in the case of an in-person meeting. We do not maintain a formal policy regarding director attendance at the Annual Meeting; however, it is expected that, absent compelling circumstances, directors will attend. All of our directors except one attended last year’s annual meeting.

2021 Summary Compensation Table

The following table sets forth information concerning the compensation of our named executive officers for the years ended December 31, 2021 and 2020.

​

​

​

Table of Contents

2021 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. Mr. DeStefano’s and Ms. Butler’s base salaries did not change between 2020 and 2021. The 2021 base salaries set forth in the Summary Compensation Table above are lower than the 2020 reported base salary amounts because 2020 had 27 pay periods and 2021 had 26 pay periods. The 2021 base salaries for our named executive officers following such increases are as set forth in the table below.

​

Cash-Based Incentive Compensation

2021 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 and individual performance goals. For 2021, financial performance accounted for 100% 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 individual performance goals account for an additional factor in the calculation of the amount of the bonus payment.  Individuals are rated on their achievement of individual performance goals.  The “Distinguished Performer” rating results in a factor of 1.1X the bonus amount being paid and the “Successful Performer” results in a factor of 1.0X the bonus amount being paid.  Mr. DeStefano and Ms. Butler each received a rating of Successful Performer.  Mr. Schwab received a rating of Distinguished Performer.

Each named executive officer has a target bonus opportunity under the Organizational Bonus Plan, defined as a percentage of annual base salary. For 2021, the target bonuses for our named executive officers were 90% for Mr. DeStefano, 60% for Mr. Schwab, and 40% for Ms. Butler. In February 2022, our Human Capital Committee assessed achievement against the financial metrics described above and the Board approved funding the bonus pool at 116.1% of the targeted Organizational Bonus Plan opportunity for 2021.

The actual annual cash bonuses awarded to each named executive officer for 2021 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 were 50% for Mr. DeStefano and 30% for Ms. Butler.

In 2019, Mr. DeStefano and Ms. Butler were granted awards under our 2018 Long-Term Rewards Plan with performance measured over the three-year period from January 1, 2019 to December 31, 2021. 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 Human Capital Committee assessed growth with respect to these financial metrics over the performance period and approved bonuses for all participants in the 2018 Long-Term Rewards Plan, including the named executive officers. The actual cash bonuses earned by Mr. DeStefano and Ms. Butler under the 2018 Long-Term Rewards Plan for the performance period ending in 2021 are set forth above in the Summary Compensation Table in the column entitled “Non-Equity Incentive Plan Compensation.”

​

Table of Contents

Equity Compensation

During 2021, we awarded stock options and restricted stock units (“RSUs”) to our named executive officers as the long-term incentive component of our compensation program. Our named executive officers were granted the following options and RSUs on March 1, 2021:

​

The options vest in substantially equal installments on each of the first four anniversaries of the grant date. The RSUs vest as to 50% of the shares on the second anniversary of the grant date, and as to 25% of the shares on each of the third and fourth anniversaries of the grant date.

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 2021, 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 2021 are set forth above in the Summary Compensation Table in the column entitled "All Other Compensation."

Supplemental Executive Benefits. Our executive officers are 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, provides the named executive officer with disability income equal to 80% of the named executive officer’s pre-disability base salary.

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 Proxy Statement.

Employment Agreements and Severance Arrangements

In connection with our IPO we entered into amended and restated employment agreements with each of our named executive officers that set forth the terms and conditions of each executive’s employment with us.

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 "2021 Salaries" and "Cash-Based Incentive Compensation" above for additional information regarding the base salaries and bonus opportunities of our named executive officers for 2021.

Table of Contents

Term

The initial term of Mr. DeStefano’s employment agreement expires in 2023 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 and Mr. Schwab are for indefinite terms.

Severance

If we terminate a named executive officer without cause, or 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.

The receipt of severance payments and benefits for the named executive officers 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, 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.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

​

The following table sets forth information with respect to the beneficial ownership of our Class A common stock and Class B common stock:

The number of shares beneficially owned by each stockholder as described in this proxy statement is determined under rules issued by the SEC. Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power. Applicable percentage ownership is based on 42,908,610 shares of Class A common stock and 106,807,000 shares of Class B common stock outstanding as of April 18, 2022. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of Common Stock subject to options, or other rights, held by such person that are currently exercisable or will become exercisable within 60 days of April 18, 2022, are considered outstanding, although these shares are not considered

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

​

POLICIES AND PROCEDURES FOR RELATED PERSON TRANSACTIONS

​

Our Board 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 provides 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 Audit 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.

Stockholders’ Agreement

As mentioned in the Corporate Governance Section of this Proxy Statement, Amanda Westphal Radcliffe and Stefanie Westphal Thompson, each of whom serves as a member of our Board and Jeffrey Westphal are our principal stockholders and together with their affiliated trust entities and family members, are parties to the Stockholders’ Agreement with the below 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 or a committee of our Board 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 Charter, 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 IPO 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.

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); 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 about any approaches by a third party regarding any of these matters. The Board 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, 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 becoming a public company, we elected to be treated as an S Corporation for U.S. federal income tax purposes, as a result of which our existing stockholders were required to pay income taxes attributable to our earnings. We have historically paid distributions to our former S-Corp. stockholders, which assisted them in paying such income taxes. As of July 27, 2020, our S Corporation status terminated and became subject to federal and increased U.S. state income taxes, thereafter. Our former S-corp. 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 terminated. Accordingly, we entered into an agreement with our existing stockholders in connection with our IPO. Under this agreement, we may be required to make payments in material amounts to our former S-corp. 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 such 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 also indemnify such stockholders for any interest, penalties, losses, costs or expenses arising out of any claim under the agreement. However, such 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 such stockholders’ taxable income for any period and a corresponding increase in our taxable income for any period.

Indemnification Agreements

Our Charter provides that we will indemnify our directors and officers to the fullest extent permitted by law and we have entered into indemnification agreements with all of our directors and executive officers.

OTHER MATTERS

​

DELINQUENT SECTION 16(A) REPORTS

​

Section 16(a) of the Exchange Act requires our directors, executive officers and stockholders who beneficially own more than 10% of any class of our equity securities registered pursuant to Section 12 of the Exchange Act (collectively, the "Reporting Persons") to file initial statements of beneficial ownership of securities and statements of changes in beneficial ownership of securities with respect to our equity securities with the SEC. Based solely on our review of the copies of such forms received by us and upon written representations of the Reporting Persons received by us, we believe that there has been compliance with all Section 16(a) filing requirements applicable to such Reporting Persons with respect to the fiscal year ended December 31, 2021, with the exception of: Lisa Butler (one report), David DeStefano (one report), Bradley Gayton (one report), Bryan Rowland (one report), John Schwab (two reports), and J. Richard Stamm (one report).

HUMAN CAPITAL COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

​

During the fiscal year ended December 31, 2021, the members of our Human Capital Committee were Eric Andersen, Terrence Kyle, Bradley Gayton, and J. Richard Stamm. None of the members of our Human Capital Committee are a current employee. During the fiscal year ended December 31, 2021, no relationship required to be disclosed by the rules of the SEC existed aside from those identified herein.

STOCKHOLDERS’ PROPOSALS

​

Stockholders who intend to have a proposal considered for inclusion in our proxy materials for presentation at our 2023 Annual Meeting of Stockholders pursuant to Rule 14a-8 under the Exchange Act must submit the proposal to our Secretary at our offices at 2301 Renaissance Blvd., King of Prussia, PA 19406 in writing not later than December 26, 2022.

Stockholders intending to present a proposal at the 2023 Annual Meeting of Stockholders, but not to include the proposal in our proxy statement, or to nominate a person for election as a director, must comply with the requirements set forth in our Bylaws. Our Bylaws require, among other things, that our Secretary receive written notice from the stockholder of record of their intent to present such proposal or nomination not earlier than the close of business on the 120th day and not later than the close of business on the 90th day prior to the first anniversary of the preceding year’s annual meeting. Therefore, we must receive notice of such a proposal or nomination for the 2023 Annual Meeting of Stockholders no earlier than the close of business on February 14, 2023 and no later than the close of business on March 16, 2023. The notice must contain the information required by the Bylaws, a copy of which is available upon request to our Secretary. In the event that the date of the 2023 Annual Meeting of Stockholders is more than 30 days before or more than 70 days after June 14, 2022, then our Secretary must receive such written notice not earlier than the close of business on the 120th day prior to the 2023 Annual Meeting and not later than the close of business on the 90th day prior to the 2023 Annual Meeting or, if later, the 10th day following the day on which public disclosure of the date of such meeting is first made by us. SEC rules permit management to vote proxies in its discretion in certain cases if the stockholder does not comply with this deadline and, in certain other cases notwithstanding the stockholder’s compliance with this deadline.

We reserve the right to reject, rule out of order, or take other appropriate action with respect to any proposal that does not comply with these or other applicable requirements.

OTHER MATTERS AT THE ANNUAL MEETING

​

Our Board is not aware of any matter to be presented for action at the Annual Meeting other than the matters referred to above and does not intend to bring any other matters before the Annual Meeting. However, if other matters should come before the Annual Meeting, it is intended that holders of the proxies will vote thereon in their discretion.
