QUESTIONS AND ANSWERS ABOUT THE 2021 ANNUAL MEETING OF STOCKHOLDERS

​

WHO IS ENTITLED TO VOTE AT THE ANNUAL MEETING?

​

The Record Date for the Annual Meeting is March 23, 2021. 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 generally. 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, electronically or 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.

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.

​

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 (1) has not received voting instructions from the beneficial owner and (2) 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. Broker non-votes count for purposes of determining whether a quorum is present.

WHERE CAN I FIND THE VOTING RESULTS OF THE 2021 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

​

At the Annual Meeting, four Class I Directors, Amanda Radcliffe, Stefanie Thompson, Kevin Robert, and Bradley Gayton, are to be elected to hold office until the Annual Meeting of Stockholders to be held in 2024 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 of directors. The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the four nominees receiving the highest number of affirmative “FOR” votes will be elected as Class I Directors. Votes withheld and broker non-votes will have no effect on the outcome of the vote on this proposal.

Our board of directors currently consists of eight members, which includes on employee director, our President and Chief Executive Officer, David DeStefano whose detailed information can be found in the Executive Officer section of this Proxy Statement. Our amended and restated certificate of incorporation and amended and restated bylaws 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. Our current non-employee directors are:

​

Jeffrey Westphal will be leaving the board of directors in May 2021 and Bradley Gayton is standing for election at the Annual Meeting described below in this Proposal 1.

Our board of directors 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 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.

In connection with the initial public offering (“IPO”) of our Class A common stock in July 2021, we entered into a Stockholders’ Agreement with Amanda Westphal Radcliffe, Stefanie Westphal Thompson and Jeffrey Westphal, each of whom serves as a member of our board of directors, and their affiliated trust entities and family members (the “Stockholders’ Agreement”). Under the Stockholders’ Agreement, Mr. Westphal has nominated Bradley Gayton and Ms. Radcliffe and Ms. Thompson have nominated themselves, to be their respective nominees for the applicable elections to our Board. As a result of the Stockholders ‘Agreement and the aggregate voting power of the parties to the agreement, we expect that the parties to the agreement acting in conjunction will control the election of directors at the Company. For more information, see “Corporate Governance—Stockholders’ Agreement.”

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.

VOTE REQUIRED

​

The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the four nominees receiving the highest number of affirmative "FOR" votes will be elected as Directors. Votes withheld and broker non-votes will have no effect on the outcome of the vote on this proposal.

Prior to joining the Company, Mr. DeStefano was Principal and Vice President at The Mid Atlantic Companies Ltd. Mr. DeStefano is also on the Advisory Board for Corporate Social Responsibility at the Satell Institute and is on the Board of Trustees of the Joseph Fund in Camden, New Jersey. Mr. DeStefano received a BS in Finance from Lehigh University. We believe that Mr. DeStefano is qualified to serve on our board of directors because of the perspective and experience he brings as our Chief Executive Officer and his knowledge of our Company and our business.

PROPOSAL 2: Ratification of Appointment of Independent Registered Public Accounting Firm

​

Our Audit Committee has appointed Crowe LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021. Our Board has directed that this appointment be submitted to our stockholders for ratification. Although ratification of our appointment of Crowe LLP is not required, we value the opinions of our stockholders and believe that stockholder ratification of our appointment is a good corporate governance practice.

On March 4, 2021, our Audit Committee approved the engagement of Crowe LLP as the Company’s independent registered public accounting firm to serve as our independent registered public accounting firm for the fiscal year ended December 31, 2021. 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, 2022. 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 OF DIRECTORS

​

​

Report of the Audit Committee of the Board of Directors

​

The Audit Committee has reviewed Vertex’s audited financial statements for the fiscal year ended December 31, 2020 and has discussed these financial statements with management and Vertex’s independent registered public accounting firm. 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 Securities and Exchange Commission (“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 registered public accountants their independence.

Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, 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, 2020.

Board of Directors

Please see the biographies and term information for each director set forth in Proposal 1 of this Proxy Statement.

​

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 by writing to our Secretary at our offices at 2301 Renaissance Blvd., King of Prussia, PA 19406.

FAMILY RELATIONSHIPS

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

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, each of whom serves as a member of our board of directors, and their affiliated trust entities and family members.

12

Table of Contents

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 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. 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 of directors 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 of directors has determined that Eric Andersen, Terrence Kyle, Kevin Robert, and J. Richard 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 (“NASDAQ”). In addition, the director candidate, Bradley Gayton, 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 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.

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. In the future, we may elect to continue to rely on such 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.

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’

13

Table of Contents

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 (ii) 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

Table of Contents

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 of directors 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 (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 OF DIRECTORS AT MEETINGS

​

There were six meetings of the Board during the fiscal year ended December 31, 2020. During the fiscal year ended December 31, 2020, 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 is 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.

EXECUTIVE SESSIONS

​

Our non-employee directors meet in regularly scheduled executive sessions. Such meetings are presided over by a director selected on a meeting-by-meeting basis by a majority of the independent directors present.

2020 Summary Compensation Table

The following table sets forth information concerning the compensation of our named executive officers for the years ended December 31, 2020 and 2019.

​

​

17

Table of Contents

2020 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. Schwab’s 2020 salary was originally based on the negotiated salary set forth in his employment agreement as described below. The 2020 annual base salaries for Mr. DeStefano and Ms. Butler were increased in early 2020 in connection with our annual performance review process and the base salaries of all of our named executive officers were increased in connection with our IPO. The 2020 base salaries for our named executive officers following such increases are as set forth in the table below.

​

​

Cash-Based Incentive Compensation

2020 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 2020, financial performance accounted for 90% 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 2020 were based on our progress against critical business objectives and accounted for 10% 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 2020, the target bonuses for our named executive officers were 90% for Mr. DeStefano, 40% for Ms. Butler and 60% for Mr. Schwab. In February 2021, our Human Capital Committee assessed achievement against the financial and non-financial metrics described above and the board of directors approved funding the bonus pool at 100.7% of the targeted Organizational Bonus Plan opportunity for 2020. The Human Capital Committee also considered individual performance of our named executive officers for the year when determining awards under the Organization Bonus Plan and determined to award Mr. DeStefano an additional 10% of his target opportunity based on his exceptional performance during the year.

The actual annual cash bonuses awarded to each named executive officer for 2020 performance are set forth above in the Summary Compensation Table in the column entitled "Non-Equity Incentive Plan Compensation."

18

Table of Contents

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% Ms. Butler.

In early 2018, 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, 2018 to December 31, 2020. 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 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 2020 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 2020, the named executive officers were granted awards under the 2018 Long-Term Rewards Plan for a three-year performance period from January 1, 2020 to December 31, 2022. 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

Treatment of Equity Awards in Connection with our IPO

Prior to our IPO, we granted stock appreciation rights (“SARs”) as the long-term incentive component of our compensation program. The SARs generally vested 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. Certain current and former service providers had also been granted options to purchase our Class B common stock.

In connection with our IPO, the outstanding SARs and options to purchase Class B common stock held by our named executive officers were amended so that they became options to purchase shares of our Class A common stock. The options cover an equal number of shares as the amended awards and have an exercise price per share equal to the base or exercise price of the amended award. Certain options that resulted from the amendment of outstanding SARs were automatically exercised in connection with the IPO. Those options that remain outstanding following our IPO continue to vest pursuant to the same vesting schedule that applied to the amended award.

2020 Equity Awards

Mr. Schwab was granted 496,473 SARs in connection with his commencement of employment with us in January 2020. Mr. DeStefano and Ms. Butler were not granted any SARs during 2020.

In connection with our IPO, we began granting restricted stock as the long-term incentive component of our compensation program and Mr. DeStefano was granted 210,527 shares of restricted stock. The shares of restricted stock granted to Mr. DeStefano vest in substantially equal installments on each of the first, second and third anniversaries of the grant date, subject to continued service to the Company through each applicable vesting date. In addition, we granted each of Ms. Butler and Mr. Schwab 2,632 fully vested shares of stock in connection with our IPO. In addition, each employee, including each named executive officer, was granted 53 shares of restricted stock, which vest on the one year anniversary of the date of grant.

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 2020, 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 2020 are set forth above in the Summary Compensation Table in the column entitled "All Other Compensation."

Supplemental Executive Benefits. Prior to our IPO, certain of 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 pre-disability base salary. For 2020, Mr. DeStefano was reimbursed for the premiums paid for such supplemental life and disability insurance and such amounts are set forth in the “All Other Compensation” column of the Summary Compensation Table above.

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.

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.

Each of our named executive officers 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. 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; or (ix) refusal to follow any reasonable and lawful direction of the board of directors or any person to whom the executive reports, if applicable.

For purposes of the employment agreement, "good reason" is generally defined to mean, subject to certain notice and cure rights, (i) the Company’s material breach of the employment agreement, (ii) the material diminution of the executive’s duties, (iii) a material decrease in the executive’s annual base salary, or (iv) any relocation of the executive’s principal office by more than fifty (50) miles.

Restrictive Covenants

Pursuant to their employment agreements, the executives have agreed to refrain from competing with us or soliciting our employees, customers, clients or prospects, in each case, while employed and following termination of employment for a period of 24 months for Mr. DeStefano or 12 months for Ms. Butler and Mr. Schwab. During the applicable restricted period, the executives are also obligated to disclose to us certain business opportunities that relate to the business of the Company, its subsidiaries or affiliates. The executives are also bound by certain confidentiality and assignment of inventions obligations.

Under this program our non-employee directors receive the following amounts for their services on our board of directors:

​

Director fees under the program are 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. 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.

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 27,525,471 shares of Class A common stock and 120,117,000 shares of Class B common stock outstanding as of March 23, 2021. 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 March 23, 2021, are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person. Unless otherwise indicated, the address of all listed stockholders is 2301 Renaissance Blvd., King of Prussia, PA 19406. Each of the stockholders listed has sole voting and investment power with respect to the shares beneficially owned by the stockholder unless noted otherwise, subject to community property laws where applicable.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

​

POLICIES AND PROCEDURES FOR RELATED PERSON TRANSACTIONS

​

Our board of directors 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, Stefanie Westphal Thompson and Jeffrey Westphal, each of whom serves as a member of our board of directors are our principal stockholders and together with their affiliated trust entities and family members, are parties to 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.

27

Table of Contents

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.

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 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

28

Table of Contents

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 amended and restated certificate of incorporation 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, 2020, with the exception of: Lisa Butler, John Schwab, Amanda Radcliffe, Kevin Robert.

HUMAN CAPITAL COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

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.
