PROXY STATEMENT

Annual Meeting of Stockholders

June 4, 2026

**GENERAL INFORMATION** 

**Why am I being provided with these materials?** 

Pursuant to rules adopted by the Securities and Exchange Commission (the "SEC"), we have elected to provide access to our proxy materials over the internet. Accordingly, the Notice of Internet Availability of Proxy Materials was mailed, and this Proxy Statement, annual report, and the form of proxy were first sent or made available to stockholders on or about April 23, 2026. We have provided these proxy materials to you in connection with the solicitation by the Board of Directors (the "Board" or "Board of Directors") of Definitive Healthcare Corp. ("we," "our," "us" and the "Company") of proxies to be voted at our Annual Meeting of Stockholders to be held on June 4, 2026 (the "Annual Meeting"), and at any postponements or adjournments of the Annual Meeting. You are invited to attend the Annual Meeting and vote your shares or to vote your shares in advance by proxy via the Internet, by telephone, or by mail.

**What am I voting on?** 

There are four proposals scheduled to be voted on at the Annual Meeting:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Proposal No. 1: To elect the three Class II directors of Definitive Healthcare Corp. named in this Proxy Statement, each to serve a three-year term expiring at the 2029 annual meeting of stockholders and until such director's successor is duly elected and qualified, or until such director's earlier death, resignation or removal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Proposal No. 2: To ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Proposal No. 3: To approve an amendment to the Definitive Healthcare Corp. 2021 Equity Incentive Plan (the "2021 Plan"), to increase the number of shares of Common Stock that we will have authority to grant under the 2021 Plan by 15,000,000 from 30,972,789 to 45,972,789.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Proposal No. 4: To approve, on an advisory basis, the compensation of the Company's Named Executive Officers, as disclosed in this Proxy Statement.

**Who is entitled to vote?** 

Stockholders of record as of the close of business on April 13, 2026 (the "Record Date") may vote at the Annual Meeting or any postponement or adjournment thereof. As of that date, there were 105,456,979 shares of our Class A Common Stock and 38,225,333 shares of our Class B Common Stock, par value $0.00001 (the "Class B Common Stock") outstanding. Holders of our Class A Common Stock have one vote for each share of Class A Common Stock held as of the Record Date, and holders of our Class B Common Stock have one vote for each share of Class B Common Stock held as of the Record Date, in each case including shares:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Held directly in your name as "stockholder of record" (also referred to as "registered stockholder"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Held for you in an account with a broker, bank, or other nominee (shares held in "street name"). Street name holders generally cannot vote their shares directly and instead must instruct the brokerage firm, bank, or nominee how to vote their shares.

Our Class A Common Stock and Class B Common Stock will vote together as a single class on all matters described in this Proxy Statement for which stockholder votes are being solicited.

------

**What constitutes a quorum?** 

The presence in person or by proxy of the holders of record of a majority in voting power of the shares entitled to vote at the Annual Meeting shall constitute a quorum. Abstentions, "withhold" votes, and shares represented by "broker non-votes" that are present in person or by proxy and entitled to vote at the Annual Meeting are counted for purposes of determining a quorum.

**What is a "broker non-vote"?** 

A broker non-vote occurs when shares held through a broker are not voted with respect to a proposal because (1) the broker has not received voting instructions from the stockholder who beneficially owns the shares and (2) the broker lacks the authority to vote the shares at its discretion. Proposal Nos. 1, 3, and 4 are considered non-routine matters, and a broker will lack the authority to vote uninstructed shares at their discretion on such proposal. Proposal No. 2 is considered a routine matter, and a broker will be permitted to exercise its discretion to vote uninstructed shares on this proposal.

**How many votes are required to approve each proposal?** 

For Proposal No. 1, under our Amended and Restated Certificate of Incorporation ("Charter"), directors are elected by the plurality of the votes cast by the holders of shares present in person or represented by proxy at the meeting and entitled to vote thereon. There is no cumulative voting. Director nominees who receive the greatest number of affirmative votes will be elected. In an uncontested election where the number of nominees equals the number of director seats up for election, all the nominees will be elected as long as there is a quorum and they receive at least one vote. Under our Corporate Governance Guidelines, we maintain a policy that requires a director in an uncontested election who does not receive a majority of the votes cast to tender his or her resignation from the Board and all committees thereof. Under our Corporate Governance Guidelines, a director nominee shall have failed to receive the affirmative vote of a majority of votes cast if the number of "withhold" votes in respect of such director nominee's election exceeds the number of votes "for" such director nominee's election (excluding broker non-votes). The Nominating and Corporate Governance Committee will assess the appropriateness of the nominee continuing to serve as a director and will recommend to the Board the action to be taken with respect to the resignation. The Board will act on the Nominating and Corporate Governance Committee's recommendation and publicly disclose its decision and rationale within 90 days from the publication of the election results.

For Proposal No. 2, under our Bylaws, approval of the proposal requires the affirmative vote of the holders of a majority in voting power of the shares of stock present in person or by proxy and entitled to vote thereon. It is important to note that Proposal No. 2 is advisory and therefore not binding on the Board. While the ratification of Deloitte & Touche LLP as our independent registered public accounting firm is not required by our Bylaws or otherwise, if our stockholders fail to ratify the selection, we will consider it notice to the Board and the Audit Committee to consider, in their discretion, the selection of a different firm. In addition, even if the selection is ratified, the Board and the Audit Committee may, in their discretion, direct the appointment of a different firm if at any time during the year they determine that such a change would be in the best interests of the Company and its stockholders.

For Proposal No. 3, under our Bylaws, approval of the proposal requires the affirmative vote of the holders of a majority in voting power of the shares of stock present in person or by proxy and entitled to vote thereon. Proposal No. 3 is not advisory; stockholder approval is binding and is required under applicable Nasdaq listing rules because Proposal No. 3 relates to a material amendment to our equity compensation plan.

For Proposal No. 4, under our Bylaws, approval of the proposal requires the affirmative vote of the holders of a majority in voting power of the shares of stock present in person or by proxy and entitled to vote thereon. It is important to note that Proposal No. 4 is advisory and therefore not binding on the Board. Nevertheless, the Board and the Human Capital Management and Compensation Committee (the "HCM & Compensation Committee") value the opinions of stockholders in this matter and, to the extent there is any significant vote in opposition to the compensation of the Company's named executive officers, even if less than a majority, the Board will consider the stockholders' concerns and evaluate any appropriate next steps.

**How are votes counted?** 

With respect to the election of directors (Proposal No. 1), you may vote "FOR" or "WITHHOLD" with respect to each nominee. Votes that are "withheld" will not count as a vote "FOR" or "AGAINST" a director because directors are elected by plurality voting; however, votes that are "withheld" may trigger the director resignation policy set forth in our Corporate Governance Guidelines as described elsewhere in this Proxy Statement. Broker non-votes will have no effect on the outcome of Proposal No. 1 and there will not be any abstentions on this proposal.

------

With respect to the ratification of our independent registered public accounting firm (Proposal No. 2), you may vote "FOR," "AGAINST," or "ABSTAIN." Abstentions will have the same effect as a vote "AGAINST" Proposal No. 2. Because brokers have the discretionary authority to vote on Proposal No. 2, we do not expect any broker non-votes on this proposal.

With respect to approval of an increase in shares in the 2021 Stock Plan (Proposal No. 3), you may vote "FOR," "AGAINST," or "ABSTAIN." Abstentions will have the same effect as a vote "AGAINST" Proposal No. 3. Broker non-votes will have no effect on the outcome of Proposal No. 3.

With respect to advisory approval of the compensation of our named executive officers (Proposal No. 4), you may vote "FOR," "AGAINST," or "ABSTAIN." Abstentions will have the same effect as a vote "AGAINST" Proposal No. 4. Broker non-votes will have no effect on the outcome of Proposal No. 4.

If you sign and submit your proxy card without voting instructions, your shares will be voted in accordance with the recommendation of the Board with respect to the Proposals.

We are not aware of any matters to be voted on by stockholders at the Annual Meeting other than those referenced above. If any matter is properly presented at the Annual Meeting, your executed proxy gives your proxy holder discretionary authority to vote your shares in accordance with their best judgment with respect to the matter.

**How does the Board recommend that I vote?** 

Our Board recommends that you vote your shares:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•"FOR" each of the Class II director nominees set forth in this Proxy Statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•"FOR" the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•"FOR" the Share Increase Proposal for the 2021 Plan; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•"FOR" the advisory vote on the executive compensation of our named executive officers.

**Who will count the vote?** 

Representatives of Mediant, a BetaNXT business ("Mediant") or its designee will tabulate the votes and act as inspectors of election.

**How do I vote my shares without attending the Annual Meeting?** 

If you are a stockholder of record, you may vote by authorizing a proxy to vote on your behalf at the Annual Meeting. Specifically, you may authorize a proxy:

**PROPOSAL NO. 1—ELECTION OF CLASS II DIRECTORS** 

Our Charter provides for a classified Board of Directors divided into three classes. Chris Egan, Samuel A. Hamood, and Sastry Chilukuri constitute a class with a term that expires at the Annual Meeting (the "Class II Directors"); Scott Stephenson and Kathleen A. Winters with a term that expires at the Annual Meeting of Stockholders in 2027 (the "Class III Directors") and Kevin Coop, Jason Krantz and Lauren Young constitute a class with a term that expires at the Annual Meeting of Stockholders in 2028 (the "Class I Directors"). Upon the recommendation of the Nominating and Corporate Governance Committee, the Board of Directors has considered and nominated the following slate of nominees to serve as Class II Directors for a three-year term expiring at the Annual Meeting of Stockholders in 2029: Chris Egan, Samuel A. Hamood, and Sastry Chilukuri. Action will be taken at the Annual Meeting for the election of these three Class II Director nominees.

Unless otherwise instructed, the persons named in the form of proxy card (the "proxyholders") included with this Proxy Statement intend to vote the proxies held by them "FOR" the election of the director nominees. All of the nominees have indicated that they will be willing and able to serve as directors. Each person nominated for election has agreed to be named in this Proxy Statement and to serve if elected. We have no reason to believe that any of the nominees will be unavailable or, if elected, will decline to serve. In the event that any of the nominees should be unable to serve or for good cause will not serve, proxies will be voted for a substitute as designated by the Board, or alternatively, the Board may leave a vacancy on the Board or reduce the size of the Board.

**Nominating Agreements** 

On September 17, 2021, in connection with the initial public offering of our Class A Common Stock completed September 17, 2021 (our "IPO"), we entered into nominating agreements with each of an affiliate of Advent, Jason Krantz, and Spectrum Equity, which provide that, subject to certain stock ownership thresholds, the Company will include two designees of Advent, one designee of Jason Krantz, and one designee of Spectrum Equity, respectively, in the slate of director nominees recommended to the Company's stockholders for election, and the Company will fill any vacancy of any such designated director previously nominated by Advent, Jason Krantz, and Spectrum Equity, respectively, with a new director designated by Advent, Jason Krantz, and Spectrum Equity, respectively. The nominating agreement with Spectrum Equity has been terminated. Chris Egan and Lauren Young are the designees of Advent, and Jason Krantz is the designee of Jason Krantz.

The following information describes the offices held, other business directorships, and the term of service of each director nominee, as well as the experiences, qualifications, attributes, or skills that caused the Nominating and Corporate Governance Committee and the Board to determine that the director nominee should serve as a director.

**THE BOARD OF DIRECTORS AND CERTAIN GOVERNANCE MATTERS** 

Our business and affairs are managed under the direction of our Board. Our Charter provides that our Board must consist of at least one director, or such larger number as may be fixed from time to time by a resolution of at least a majority of the directors then in office. Our Board is composed of nine directors divided into three classes, with terms staggered according to class. See "Proposal No. 1—Election of Class II Directors" for more information.

**Director Independence and Independence Determinations** 

Under our Corporate Governance Guidelines, the Board is required to have a majority of independent directors. In making independence determinations, the Board observes all applicable requirements, including the corporate governance listing standards established by the Nasdaq Stock Market ("Nasdaq"). The Board carefully considers all relevant facts and circumstances in making an independence determination.

Our Board of Directors affirmatively determined that each of Sastry Chilukuri, Chris Egan, Samuel A. Hamood, Scott Stephenson, Kathleen Winters, and Lauren Young is independent under applicable Nasdaq listing standards. Our Board also determined that each of Sastry Chilukuri, Samuel A. Hamood, and Kathleen Winters is independent under Section 10A-3 of the Securities Exchange Act of 1934, as amended (the "Exchange Act") for purposes of serving on the Audit Committee, and that each of Scott Stephenson and Lauren Young is independent for purposes of serving on the HCM & Compensation Committee. In making its independence determinations, our Board of Directors considered and reviewed all information known to it, including information identified through annual director questionnaires. In the case of Mr. Egan and Ms. Young, our Board of Directors considered their positions as Managing Partner and Managing Director, respectively, of Advent. In the case of Mr. Stephenson, our Board of Directors considered his position as an Advisory Partner at Advent.

**Director Nomination Process** 

Currently, the Board of Directors is divided into three classes. Each year, at the Annual Meeting of Stockholders, the Board proposes a slate of director nominees for a particular class to stockholders for election to a term of three years. Stockholders may also recommend candidates for election to the Board, as described below. The Board has delegated the process of screening potential director candidates to the Nominating and Corporate Governance Committee.

The Nominating and Corporate Governance Committee is responsible for periodically reviewing with the Board the appropriate criteria that directors are required to fulfill (including experience, qualifications, attributes, skills, and other characteristics) in the context of the current make-up of the Board and the needs of the Board given the circumstances of the Company. In identifying and screening director candidates, the Nominating and Corporate Governance Committee considers whether the candidates fulfill the criteria for directors approved by the Board, including integrity, objectivity, independence, sound judgment, leadership, courage, and diversity of experience (for example, in relation to finance and accounting, strategy, risk management, technical expertise, policymaking, etc.). In addition, the Company recognizes and embraces the benefits of having a diverse Board. In evaluating the Board's composition, although the Board does not have a formal policy specifying how diversity of background and personal experience should be applied in identifying or evaluating director candidates, the Nominating and Corporate Governance Committee considers diversity among other relevant considerations, including, but not limited to, diversity of gender, age, race, ethnicity, cultural and educational background, professional experience, skills, knowledge, and length of service.

The Nominating and Corporate Governance Committee values the input of stockholders in identifying director candidates. The Nominating and Corporate Governance Committee considers recommendations for Board candidates submitted by stockholders using the same criteria it applies to recommendations from the committee, directors, and members of management. Stockholders may submit recommendations by providing the person's name and appropriate background and biographical information in writing to the Nominating and Corporate Governance Committee at Definitive Healthcare Corp., Attn: Chief Legal Officer, 492 Old Connecticut Path, Suite 401, Framingham, MA 01701. Invitations to serve as a nominee are extended by the Board via the Chair of the Board and the Chair of the Nominating and Corporate Governance Committee.

------

**Director Resignation Policy** 

Directors are elected by a plurality of the votes cast in both contested elections (elections in which the number of nominees is greater than the number of Board seats open for election) and uncontested elections (elections in which the number of nominees does not exceed the number of Board seats open for election). Under our Corporate Governance Guidelines, we maintain a policy that requires a director in an uncontested election who does not receive a majority of the votes cast to tender his or her resignation from the Board and all committees thereof. Under our Corporate Governance Guidelines, a director nominee shall have failed to receive the affirmative vote of a majority of votes cast if the number of "withhold" votes in respect of such director nominee's election exceeds the number of votes "for" such director nominee's election (excluding broker non-votes). The Nominating and Corporate Governance Committee will assess the appropriateness of the nominee continuing to serve as a director and will recommend to the Board the action to be taken with respect to the resignation. The Board will act on the Nominating and Corporate Governance Committee's recommendation and publicly disclose its decision and rationale within 90 days from the publication of the election results.

**Board Leadership Structure** 

Our Board of Directors is led by Mr. Krantz, our Executive Chairman and Founder. At this time, we believe that separate Chair and Chief Executive Officer roles are appropriate for the Company and in the best interests of the Company and its stockholders. As the former Chief Executive Officer, former Interim Chief Executive Officer, and Founder, Mr. Krantz has a deep understanding of the Company and supports and advises the Chief Executive Officer, which we believe enables the Board to understand the Company and work closely with management. In addition, we believe that separating these roles creates an environment that is more conducive to objective evaluation and oversight of management's performance, increasing management accountability, and improving the ability of the Board to monitor whether management's actions are in the best interests of the Company and its stockholders, including with respect to evaluating whether steps management is taking to manage risks are appropriate for the Company. We believe Mr. Krantz offers a robust understanding of risks facing the Company as our Founder and former Chief Executive Officer. Meanwhile, the separation of roles permits our Chief Executive Officer to focus primarily on management responsibilities as we grow our Company and encourages objective oversight of management and balanced decision-making. The Board does not have a fixed policy regarding the separation of the offices of Chair of the Board and Chief Executive Officer and believes that it should maintain the flexibility to select the Chair of the Board and its leadership structure, from time to time, based on the criteria that it deems in the best interests of the Company and its stockholders. The Board believes that this flexibility is in the best interest of the Company and that a one-size-fits-all approach to corporate governance, with a mandated independent Chair, would not result in better governance or oversight.

**Oversight of Risk Management** 

The Board is involved in the oversight of risk management related to us and our business. The Board accomplishes this oversight both directly and through its committees, which assist the Board in overseeing parts of our overall risk management and regularly report to the Board. The Audit Committee periodically reviews our accounting, reporting, and financial practices, and oversees the integrity of our financial statements, the administrative and financial controls, our compliance with legal and regulatory requirements, our procedures for the treatment of complaints regarding internal accounting controls or auditing matters, and our policies with respect to risk assessment and risk management. In addition, our Audit Committee addresses the Company's cybersecurity risk management as part of its general oversight function. The audit committee is responsible for overseeing the Company's cybersecurity risk management processes, including oversight of risks from cybersecurity threats. Through its regular meetings with management, including the finance, legal, cybersecurity, and internal control functions, the Audit Committee reviews and discusses significant areas of our business and related risks and summarizes for the Board areas of risk and any mitigating factors. In addition, the HCM & Compensation Committee reviews, at least annually, whether risks arising from the Company's compensation policies and practices for all employees, including executive officers, are reasonably likely to have a material adverse effect on the Company. For more information regarding our risk oversight governance framework, see below under "Our Commitment to ESG."

**Executive Sessions** 

As described in our Corporate Governance Guidelines, the non-management directors meet regularly in executive session without members of management present. If any of the non-management directors do not qualify as an "independent director" under applicable Nasdaq rules, at least once a year an additional executive session is held, attended only by independent directors. The executive sessions have such agendas and procedures as are determined by the non-management and independent directors, as applicable. An independent presiding director convenes and presides at such sessions. Authority in such sessions to act on behalf of the Company or the Board on any matters requires an express delegation of authority by the Board.

------

**Communications with the Board** 

As described in our Corporate Governance Guidelines, stockholders are invited to communicate to the Board or its committees by writing to Definitive Healthcare Corp., Attn: Chief Legal Officer, 492 Old Connecticut Path, Suite 401, Framingham, MA 01701. In addition, interested parties may communicate with the Chair of the Board or with the non-management and independent directors of the Company as a group by writing to Definitive Healthcare Corp., Attn: Chief Legal Officer, 492 Old Connecticut Path, Suite 401, Framingham, MA 01701.

**Committee Charters and Corporate Governance Guidelines** 

Our commitment to good corporate governance is reflected in our Corporate Governance Guidelines, which describe our Board's views and policies on a wide range of governance topics. These Corporate Governance Guidelines are reviewed from time to time by our Nominating and Corporate Governance Committee and, to the extent deemed appropriate in light of emerging practices, revised accordingly, upon recommendation to and approval by our Board of Directors.

Our Corporate Governance Guidelines, committee charters, Code of Business Conduct and Ethics, and other corporate governance documents and information are available on our website at *ir.definitivehc.com* under Governance. Any stockholder may also request them in print, without charge, by contacting the Chief Legal Officer of Definitive Healthcare Corp., at 492 Old Connecticut Path, Suite 401, Framingham, MA 01701.

**Our Commitment to ESG** 

Our Board, acting directly and through its committees, reviews and oversees our strategic plans, objectives, and risks related to sustainability, environmental, social, and governance matters ("ESG"), pursuant to our Corporate Governance Guidelines. At this time, the Board believes full board oversight, with specific elements delegated to committees, rather than assigning oversight to an existing or new committee, will ensure all directors are actively engaged in overseeing ESG risks and opportunities. Each of our committees share ESG oversight responsibilities, and each committee reports regularly to the full Board on its activities. The HCM and Compensation Committee is responsible for overseeing the policies and strategies relating to talent management. The Nominating and Corporate Governance Committee oversees our broader ESG framework and general approach to ESG reporting, and reviews and makes recommendations to the Board about significant emerging corporate governance issues and practices. The Audit Committee reviews controls and risks around information security and data privacy and approves procedures and security measures undertaken to strengthen and support compliance in this area. The Audit Committee also provides specific oversight with respect to the financial reporting elements of ESG disclosures.

**PROPOSAL NO. 2—RATIFICATION OF INDEPENDENT REGISTERED** 

**PUBLIC ACCOUNTING FIRM** 

The Audit Committee has appointed Deloitte & Touche LLP to serve as our independent registered public accounting firm for the fiscal year ending December 31, 2026.

Although ratification is not required by our Bylaws or otherwise, the Board is submitting the selection of Deloitte & Touche LLP to our stockholders for ratification because we value our stockholders' views on the Company's independent registered public accounting firm. If our stockholders fail to ratify the selection, it will be considered as notice to the Board and the Audit Committee to consider the selection of a different firm. Even if the selection is ratified, the Audit Committee, in its discretion, may select a different independent registered public accounting firm at any time if it determines that such a change would be in the best interests of the Company and our stockholders.

A representative of Deloitte & Touche LLP is expected to attend the Annual Meeting. The representative will also have the opportunity to make a statement if he or she desires to do so, and the representative is expected to be available to respond to appropriate questions.

The shares represented by your proxy will be voted "FOR" the ratification of the selection of Deloitte & Touche LLP unless you specify otherwise.

**PROPOSAL NO. 3—To approve an amendment to the 2021 Plan, to increase the number of shares of Common Stock that we will have authority to grant under the 2021 Plan BY 15,000,000 from 30,972,789 to 45,972,789**

**Background of and Rationale for the 2021 Plan Increase Proposal**

On September 15, 2021, in connection with its IPO, the Company adopted the Definitive Healthcare Corp. 2021 Equity Incentive Plan (the "Plan").

The types of Awards that may be made under the 2021 Plan include Stock Options, Stock Appreciation Rights, Restricted Stock Awards, Restricted Stock Units, or Stock-Based Awards.

As of March 31, 2026 there were (i) 5,995,317 shares of Common Stock available for grant under the 2021 Plan and (ii) 18,942,446 shares of Common Stock subject to awards outstanding under the 2021 Plan. The outstanding restricted stock units ("RSUs") have time-based and/or performance-based vesting criteria. Outstanding time-based RSUs generally vest partially on the one-year anniversary of each grant and quarterly over the subsequent two- or three-year period. Outstanding performance-based RSUs generally vest after three years upon the achievement of certain performance targets and continued service.

Equity-based compensation awards are a critical element of our overall compensation program. We believe that our long-term incentive compensation program aligns the interests of management, employees and the stockholders to create long-term stockholder value. In an effort to preserve cash and to attract, retain and motivate persons who make important contributions to our business, we would like to issue securities to our officers, directors and consultants. Management believes that the number of shares of Common Stock currently available for issuance under the Plan is insufficient to ensure it can meet its needs to provide for awards to the Plan participants for the next 12 months and that it may be insufficient in order to allow us the ability to compete successfully for talented employees and consultants. The Board of Directors has approved, subject to stockholder approval, Amendment No. 1 to the Plan, which amendment increases by 15,000,000 the number of shares that may be granted under the Plan. The amendment to our Plan will increase the number of shares of Common Stock with respect to which awards are authorized and reserved under the Plan from 30,972,789 to 45,972,789. If the amendment to the Plan is approved by our stockholders, the number of shares available for future awards will increase to 20,995,317 based on the number of shares remaining available for grant under the Plan as of March 31, 2026. The proposed Amendment No. 1 to the Plan is attached hereto as <u>Appendix A</u>.

*Purpose of the Plan*

The purpose of the Definitive Healthcare Corp. 2021 Equity Incentive Plan is to further align the interests of eligible participants with those of the Company's stockholders by providing incentive compensation opportunities tied to the performance of the Company and its Common Stock. The Plan is intended to advance the interests of the Company and increase stockholder value by attracting, retaining and motivating key personnel upon whose judgment, initiative and effort the successful conduct of the Company's business is largely dependent.

The Company believes the Plan is best designed to provide the proper incentives for our employees, directors and consultants, ensures our ability to make performance-based awards, and meets the requirements of applicable law. Additional individuals may be awarded awards under the Plan as consultants.

*Limitation on Awards and Shares Available*

Initially, the aggregate number of shares of our Common Stock that was available to be issued pursuant to stock awards under the Plan was 8,989,039 shares at inception. In addition to the base share reserve, the Plan includes an evergreen feature pursuant to which on each January 1 from 2023 to 2032, the aggregate number of shares of Common Stock that may be issued under the Plan automatically increases by the least of (i) 5% of the total number of shares of our Common Stock actually issued and outstanding on the last day of the preceding fiscal year, (ii) a number of shares of Common Stock determined by the Board; and (iii) 8,989,039 shares of our Common Stock. As of March 31, 2026, we had 18,942,446 shares of Common Stock subject to awards outstanding under the Plan. As of March 31, 2026, there are 5,995,317 shares of our Common Stock available for grants that may be made under the Plan.

As of March 31, 2026, the fair market value of a share of our Common Stock was $1.23 measured on the basis of the closing sales price on that date as reported on Nasdaq.

**Summary of the 2021 Plan**

The principal provisions of the Plan are summarized below.

This summary, however, does not purport to be a complete description of all provisions of the Plan and is qualified in its entirety by reference to the Plan.

*Administration*

The Plan is administered by the HCM & Compensation Committee. To the extent deemed necessary by the Board, each HCM & Compensation Committee member shall satisfy the requirements for (i) an "independent director" under rules adopted by the NASDAQ or other principal exchange on which the Common Stock is then listed and (ii) a "nonemployee director" within the meaning of Rule 16b-3 under the Exchange Act. Notwithstanding the foregoing, the mere fact that a HCM & Compensation Committee member shall fail to qualify under any of the foregoing requirements shall not invalidate any Award made by the HCM & Compensation Committee which Award is otherwise validly made under the Plan. The Board may exercise all powers of the HCM & Compensation Committee hereunder and may directly administer the Plan. Neither the Company nor any member of the Board or HCM & Compensation Committee shall be liable for any action or determination made in good faith by the Board or HCM & Compensation Committee with respect to the Plan or any Award thereunder.

*Share Usage*

To the extent that an Award is canceled, expired, repurchased, forfeited, surrendered, exchanged for cash, settled in cash or by delivery of fewer shares of Common Stock than the number underlying the Award, or otherwise terminated without delivery of the shares of Common Stock to the Participant, the unissued shares of Common Stock will (i) not be deemed to have been delivered under the Plan, (ii) be available for future Awards under the Plan, and (iii) increase the share reserve by one share for each share that is retained by or returned to the Company. Shares of Common Stock that are withheld from any Award granted under the Plan in payment of the exercise, base or purchase price or taxes relating to such an Award shall be available for future Awards under the Plan and shall increase the share reserve by one share for each share that is retained by or returned to the Company. Shares of Common Stock repurchased by the Company on the open market with the proceeds of an Option will be deemed to have been delivered under the Plan and will not be available for future Awards under the Plan. The payment of dividend equivalents in cash in conjunction with any outstanding Award shall not count against the share reserve.

*Eligibility*

Any Eligible Person (which includes non-employee members of the Board as well as officers, employees and natural persons who

are consultants, other personal service providers of the Company or a subsidiary) may be selected by the HCM & Compensation Committee to receive an Award and become a Participant. The HCM & Compensation Committee has the authority, in its discretion, to determine and designate from time to time those Eligible Persons who are to be granted Awards, the types of Awards to be granted, the number of shares of Common Stock or units subject to Awards to be granted and the terms and conditions of such Awards consistent with the terms of the Plan. In selecting Eligible Persons to be Participants, and in determining the type and amount of Awards to be granted under the Plan, the HCM & Compensation Committee shall consider any and all factors that it deems relevant or appropriate. Designation of a Participant in any year shall not require the HCM & Compensation Committee to designate such Person to receive an Award in any other year or, once designated, to receive the same type or amount of Award as granted to such Participant in any other year. As of April 1, 2026, eligibility to participate in the Plan is expected to include: (i) four non-employee directors (excluding Mr. Egan and Ms. Young, who, as employees of Advent, receive no compensation for their service on the Board or its committees); and (ii) approximately 256 employees, including our two employee directors and our executive officers.

*Awards*

The Plan provides for the grant of Stock Options, Stock Appreciation Rights, Restricted Stock Awards, RSUs, and Stock-Based Awards to Eligible Persons. The terms of the awards will be set forth in an award agreement, consistent with the terms of the Plan. No stock option will be exercisable later than ten years after the date it is granted.

------

*Stock Options*

Stock Options may be granted to any Eligible Person selected by the HCM & Compensation Committee, except that Incentive Stock Options may be granted only to an employee of the Company or a subsidiary, as defined in tax regulations. Stock Options shall be designated on the Date of Grant, in the discretion of the HCM & Compensation Committee, as Incentive Stock Options or as Nonqualified Stock Options. All Stock Options granted under the Plan are intended to comply with or be exempt from the requirements of Section 409A of the Code, to the extent applicable.

*Stock Appreciation Rights*

Stock Appreciation Rights may be granted to any Eligible Person selected by the HCM & Compensation Committee. Stock Appreciation Rights may be granted on a basis that allows for the exercise of the right by the Participant, or that provides for the automatic exercise or payment of the right upon a specified date or event. Stock Appreciation Rights shall be non-transferable, except as provided in Section 14.3 hereof. All Stock Appreciation Rights granted under the Plan are intended to comply with or otherwise be exempt from the requirements of Section 409A of the Code, to the extent applicable.

*Restricted Stock and Stock Bonuses*

Restricted Stock Awards may be granted to any Eligible Person selected by the HCM & Compensation Committee. The HCM & Compensation Committee may require the payment by the Participant of a specified purchase price in connection with any Restricted Stock Award.

*RSUs*

RSUs may be granted to any Eligible Person selected by the HCM & Compensation Committee. The value of each RSU is equal to the Fair Market Value of a share of Common Stock on the applicable date or time period of determination, as specified by the HCM & Compensation Committee. RSUs shall be subject to such restrictions and conditions as the HCM & Compensation Committee shall determine. RSUs shall be non-transferable, except as provided in Section 14.3 of the 2021 Plan.

*Other Awards*

The HCM & Compensation Committee may grant other types of equity-based or equity-related awards not otherwise described by the terms of the Plan, in such amounts and subject to such terms and conditions, as the HCM & Compensation Committee shall determine. Such awards may be based upon attainment of performance goals established by the HCM & Compensation Committee and may involve the transfer of actual shares to participants, or payment in cash or otherwise of amounts based on the value of shares.

*Awards Granted to Non-Employee Directors*

No Non-Employee Director may be granted, during any calendar year, Awards having a fair value (determined on the date of grant) that, when added to all cash compensation paid to the Non-Employee Director in respect of the Non-Employee Director's service as a member of the Board for such calendar year, exceeds (i) $1,000,000 in the year that the director is first elected to serve as a director on the Board; and (ii) $500,000 in each subsequent year.

*Amendment and Termination*

The Board has adopted this plan and the Plan became effective September 14, 2021 (the "Effective Date"). Subject to earlier termination by the Board, the Plan shall terminate on the tenth anniversary of the Effective Date.

The Board may from time to time and in any respect, amend, modify, suspend or terminate the Plan; provided, however, that no amendment, modification, suspension or termination of the Plan shall materially and adversely affect any Award theretofore granted without the consent of the Participant or the permitted transferee of the Award. The Board may seek the approval of any amendment, modification, suspension or termination by the Company's stockholders to the extent it deems necessary in its discretion for purposes of compliance with Section 422 of the Code or for any other purpose, and shall seek such approval to the extent it deems necessary in its discretion to comply with applicable law or listing requirements of NASDAQ or other exchange or securities market. Notwithstanding the foregoing, the Board shall have broad authority to amend the Plan or any Award under the Plan without the consent of a Participant to the extent it deems necessary or desirable in its discretion to comply with, take into account changes in, or interpretations of, applicable tax laws, securities laws, employment laws, accounting rules and other applicable laws, rules and regulations.

------

*Certain Adjustments*

If there is any change with respect to the outstanding shares of Common Stock by reason of any recapitalization, reclassification, stock dividend, extraordinary cash dividend, stock split, reverse stock split or other distribution with respect to the shares of Common Stock or any merger, reorganization, consolidation, combination, spin-off or other corporate event or transaction or any other change affecting the Common Stock (other than regular cash dividends to stockholders of the Company), the HCM & Compensation Committee shall, in the manner and to the extent it considers appropriate and equitable to the Participants and consistent with the terms of the Plan, cause an adjustment to be made to the maximum number and kind of shares of Common Stock or other securities provided in in the share reserve and in the automatic annual increase the number and kind of shares of Common Stock, units or other securities or rights subject to then outstanding Awards, the exercise, base or purchase price for each share or unit or other security or right subject to then outstanding Awards, other value determinations applicable to the Plan and/or outstanding Awards, and/or (v) any other terms of an Award that are affected by the event.

*Repricing Prohibited*

Subject to the adjustment provisions described above and other than in connection with a Change in Control, without the prior approval of the Company's stockholders, neither the HCM & Compensation Committee nor the Board may cancel a Stock Option or Stock Appreciation Right when the exercise price or base price per share exceeds the Fair Market Value of one share of Common Stock in exchange for cash or another Award or cause the cancellation, substitution or amendment of a Stock Option or Stock Appreciation Right that would have the effect of reducing the exercise price or base price of such a Stock Option previously granted under the Plan or otherwise approve any modification to such a Stock Option or Stock Appreciation Right, that would be treated as a "repricing" under the then applicable rules, regulations or listing requirements adopted by the NASDAQ or other principal exchange on which the Common Stock is then listed.

*Changes in Control*

Upon the occurrence of a Change in Control, all outstanding Awards shall either be (a) continued or assumed by the Company (if it is the surviving company or corporation) or by the surviving company or corporation or its parent (with such continuation or assumption including conversion into the right to receive securities, cash or a combination of both), or (b) substituted by the surviving company or corporation or its parent for awards (with such substitution including conversion into the right to receive securities, cash or a combination of both), with substantially similar terms for outstanding Awards (with appropriate adjustments to the type of consideration payable upon settlement of the Awards or other relevant factors, and with any applicable performance conditions deemed achieved (i) for any completed performance period, based on actual performance, or (ii) for any partial or future performance period, at the greater of the target level or actual performance, in each case as determined by the HCM & Compensation Committee (with the Award remaining subject only to time vesting), unless otherwise provided in an Award Agreement).

However, the extent that outstanding Awards are not continued, assumed or substituted upon the occurrence of a Change in Control, the HCM & Compensation Committee is authorized (but not obligated) to make adjustments in the terms and conditions of outstanding Awards, including without limitation the following (or any combination thereof): (a) acceleration of exercisability, vesting and/or payment of outstanding Awards immediately prior to the occurrence of such event or upon or following such event; (b) upon written notice, providing that any outstanding Stock Options and Stock Appreciation Rights are exercisable during a period of time immediately prior to the scheduled consummation of the event or such other period as determined by the HCM & Compensation Committee (contingent upon the consummation of the event), and at the end of such period, such Stock Options and Stock Appreciation Rights shall terminate to the extent not so exercised within the relevant period; and (c) cancellation of all or any portion of outstanding Awards for fair value (in the form of cash, Common Shares, other property or any combination thereof) as determined in the sole discretion of the HCM & Compensation Committee; provided, however, that, in the case of Stock Options and Stock Appreciation Rights or similar Awards, the fair value may equal the excess, if any, of the value or amount of the consideration to be paid in the Change in Control transaction to holders of shares of Common Stock (or, if no such consideration is paid, Fair Market Value of the shares of Common Stock) over the aggregate exercise or base price, as applicable, with respect to such Awards or portion thereof being canceled, or if there is no such excess, zero; provided, further, that if any payments or other consideration are deferred and/or contingent as a result of escrows, earn outs, holdbacks or any other contingencies, payments under this provision may be made on substantially the same terms and conditions applicable to, and only to the extent actually paid to, the holders of Common Shares in connection with the Change in Control.

*Miscellaneous*

The Plan also contains provisions with respect to payment of exercise prices, vesting and expiration of awards, treatment of awards upon the sale of our company, transferability of awards, and tax withholding requirements. Various other terms, conditions, and limitations apply, as further described in the Plan.

------

**Federal Income Tax Consequences**

The following is a general summary as of this date of the federal income tax consequences to us and to U.S. Participants for Awards granted under the Plan. The federal tax laws may change and the federal, state and local tax consequences for any Participant will depend upon his or her individual circumstances. Tax consequences for any particular individual may be different. This summary does not purport to be complete, and does not discuss state, local or non-U.S. tax consequences.

*Nonqualified Stock Options*

The grant of Nonqualified Stock Options under the Plan will not result in any federal income tax consequences to the Participant or to the Company. Upon exercise of a non-qualified stock option, the Participant is subject to income taxes at the rate applicable to ordinary compensation income on the difference between the option exercise price and the fair market value of the shares at the time of exercise. This income is subject to withholding for federal income and employment tax purposes. Any gain or loss on the Participant's subsequent disposition of the shares of Common Stock will receive long- or short-term capital gain or loss treatment, depending on whether the shares are held for more than one year following exercise. The Company does not receive a tax deduction for any such gain.

Nonqualified Stock Options can be considered non-qualified deferred compensation and subject to Section 409A of the Code. Nonqualified Stock Options that do not meet the requirements of Code Section 409A can result in the acceleration of income recognition, an additional 20% tax obligation, plus penalties and interest.

*Incentive Stock Options*

The grant of an incentive stock option under the Plan will not result in any federal income tax consequences to the Participant or to the Company. A Participant recognizes no federal taxable income upon exercising an incentive stock option (subject to the alternative minimum tax rules discussed below), and the Company receives no deduction at the time of exercise. In the event of a disposition of stock acquired upon exercise of an incentive stock option, the tax consequences depend upon how long the Participant has held the shares of Common Stock. If the Participant does not dispose of the shares within two years after the incentive stock option was granted, nor within one year after the incentive stock option was exercised, the Participant will recognize a long-term capital gain (or loss) equal to the difference between the sale price of the shares and the exercise price. The Company is not entitled to any deduction under these circumstances.

If the Participant fails to satisfy either of the foregoing holding periods (referred to as a "disqualifying disposition"), he or she must recognize ordinary income in the year of the disposition. The amount of ordinary income generally is the lesser of (i) the difference between the amount realized on the disposition and the exercise price or (ii) the difference between the fair market value of the stock at the time of exercise and the exercise price. Any gain in excess of the amount taxed as ordinary income will be treated as a long- or short-term capital gain, depending on whether the stock was held for more than one year.

The "spread" under an incentive stock option — i.e., the difference between the fair market value of the shares at exercise and the exercise price — is classified as an item of adjustment in the year of exercise for purposes of the alternative minimum tax. If a Participant's alternative minimum tax liability exceeds such Participant's regular income tax liability, the Participant will owe the larger amount of taxes. In order to avoid the application of alternative minimum tax with respect to incentive stock options, the Participant must sell the shares within the calendar year in which the incentive stock options are exercised. However, such a sale of shares within the year of exercise will constitute a disqualifying disposition, as described above.

*Stock Appreciation Rights*

Recipients of stock appreciation rights ("SARs") generally should not recognize income until the SAR is exercised (assuming there is no ceiling on the value of the right). Upon exercise, the recipient will normally recognize taxable ordinary income for federal income tax purposes equal to the amount of cash and fair market value of the shares, if any, received upon such exercise. Recipients who are employees will be subject to withholding for federal income and employment tax purposes with respect to income recognized upon exercise of a SAR. Recipients will recognize gain upon the disposition of any shares received on exercise of a SAR equal to the excess of (i) the amount realized on such disposition over (ii) the ordinary income recognized with respect to such shares under the principles set forth above. That gain will be taxable as long- or short-term capital gain depending on whether the shares were held for more than one year.

A SAR can also be considered non-qualified deferred compensation and subject to Section 409A of the Code. A SAR that does not meet the requirements of Code Section 409A can result in the acceleration of income recognition, an additional 20% tax obligation, plus penalties and interest.

------

Restricted Stock Awards subject to a "substantial risk of forfeiture" within the meaning of Section 83 of the Code to the extent the award will be forfeited in the event that the Participant ceases to provide services to the Company. As a result of this substantial risk of forfeiture, the recipient will not recognize ordinary income at the time of the award, unless the Participant is retirement eligible. Instead, the recipient will recognize ordinary income on the date when the stock is no longer subject to a substantial risk of forfeiture, or when the stock becomes transferable, if earlier. The recipient's ordinary income is measured as the difference between the amount paid for the stock, if any, and the fair market value of the stock on the earlier of those two dates.

The recipient may accelerate his or her recognition of ordinary income, if any, and begin his or her capital gains holding period by timely filing (i.e., within thirty (30) days of the award) an election pursuant to Section 83(b) of the Code. In such event, the ordinary income recognized, if any, is measured as the difference between the amount paid for the stock, if any, and the fair market value of the stock on the date of award, and the capital gain holding period commences on such date. The ordinary income recognized by a recipient that is an employee or former employee will be subject to tax withholding by the Company.

*RSUs*

With respect to awards of RSUs, no taxable income is reportable when the RSUs are granted to a Participant. Upon vesting of the RSUs, the recipient will recognize ordinary income in an amount equal to the fair value of the vested shares on the vesting date. The ordinary income recognized by a recipient that is an employee or former employee will be subject to tax withholding by the Company.

RSUs also can be considered non-qualified deferred compensation and subject to Section 409A of the Code. A grant of RSUs that does not meet the requirements of Code Section 409A will result in an additional 20% tax obligation, plus penalties and interest to such recipient.

*Cash Awards*

Upon receipt of cash, the Participant will have taxable ordinary income, in the year of receipt, equal to the cash received. Any cash received will be subject to tax withholding by the Company.

*Tax Effect for the Company*

Unless limited by Section 162(m) of the Code, the Company generally will be entitled to a tax deduction in connection with an award under the Plan in an amount equal to the ordinary income realized by a recipient at the time the recipient recognizes such income (for example, when restricted stock is no longer subject to the risk of forfeiture), so long as the Company complies with applicable reporting and withholding requirements.

The Plan is not qualified under the provisions of section 401(a) of the Code and is not subject to any provisions of the Employee Retirement Income Security Act of 1974.

*Grants Under the Plan*

The future benefits or amounts that would be received under this amendment to the Plan are discretionary and are therefore not determinable at this time. Similarly, the benefits or amounts which would have been received by or allocated to executive officers and our other employees for the last completed fiscal year if this amendment to the Plan had been in effect cannot be determined. For more information about awards granted in fiscal year 2025 to the NEOs, see "*Executive Compensation Tables*." For more information about awards granted in fiscal year 2025 to our outside directors, see "*Director Compensation*."

**Vote Required**

The affirmative vote of a majority of the shares present in person or represented by proxy and entitled to vote on this proposal at the 2026 Annual Meeting is required to approve the 2021 Plan Increase Proposal. Abstentions will have the same effect as a vote AGAINST the proposal. Broker non-votes will have no effect on this proposal

**THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" THE APPROVAL OF THE PLAN INCREASE PROPOSAL.**

**PROPOSAL NO. 4—ADVISORY VOTE ON EXECUTIVE COMPENSATION**

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, and Section 14A of the Exchange Act, the Company's shareholders are entitled to vote to approve, on an advisory basis, the compensation of the Company's named executive officers as disclosed in this proxy statement in accordance with SEC rules (commonly referred to as a "say-on-pay" resolution).

This vote is not intended to address any specific item of compensation, but rather the overall compensation of the Company's named executive officers and the philosophy, policies and practices described in this proxy statement. The compensation of the Company's named executive officers subject to the vote is disclosed in the compensation tables, and the related narrative disclosure contained in this proxy statement. As discussed in those disclosures, the Company believes that its compensation policies and decisions are focused on pay-for-performance principles, strongly aligned with our shareholders' interests, and consistent with current market practices, as evidenced by the strong support (82% of votes cast) for our 2025 say-on-pay proposal. Compensation of the Company's named executive officers is designed to enable the Company to attract and retain talented and experienced executives to lead the Company successfully in a competitive environment.

Accordingly, the Board is asking the shareholders to indicate their support for the compensation of the Company's named executive officers as described in this proxy statement by casting a non-binding advisory vote "FOR" the following resolution:

*"RESOLVED, that the compensation paid to the Company's named executive officers as disclosed pursuant to Item 402 of Regulation S-K, including the compensation tables and the narrative discussion that accompanies the compensation tables, is hereby approved, on an advisory basis."* 

Because the vote is advisory, it is not binding on the Board of Directors or the Company. Nevertheless, the views expressed by the shareholders, whether through this vote or otherwise, are important to management and the Board and, accordingly, the Board and the HCM & Compensation Committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements.

Advisory approval of this proposal requires the vote of the holders of a majority in voting power of the shares of stock present in person or by proxy and entitled to vote thereon at the annual meeting. Unless the Board decides to modify its policy regarding the frequency of soliciting advisory votes on the compensation of the Company's named executives, the next scheduled say-on-pay vote will be at the 2026 Annual Meeting of Stockholders.

**THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Represents a sign-on bonus for Mr. Graboske of $20,000.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Amounts represent the aggregate grant date fair value of RSU and PSU awards granted to our NEOs, computed in accordance with ASC Topic 718. The valuation assumptions associated with such awards are discussed in Note 18 to the Company's consolidated financial statements included in the Company's Annual Report on Form 10-K for the fiscal year ending December 31, 2025. Amounts exclude 1,283,096 and 261,628 PSU shares granted in 2025 to Mr. Coop and Ms. Heller, respectively, which did not meet the grant date criteria under ASC Topic 718. Furthermore, because Mr. Coop's 2024 Value Creation PSU is subject to market conditions, the grant date fair value reported above for such awards is determined using a Monte-Carlo simulation model, and therefore there is no separate maximum value to report for those awards. These amounts do not necessarily correspond to the actual value recognized or that may be recognized by the named executive officers upon the vesting of the RSUs or PSUs or the sale of any Common Stock acquired under such RSUs or PSUs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)Payments to our NEOs included in the "All Other Compensation" column for 2025 include the following: (i) for Mr. Coop, 401(k) matching contributions and health insurance premiums of $22,522 (ii) for Ms. Heller, 401(k) matching contributions and health insurance premiums of $14,228, and (iii) for Mr. Graboske, health insurance premiums of $11,775.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)Ms. Heller assumed the role of Chief Financial Officer in June 2025, prior to which Ms. Heller served as Senior Vice President, Finance from October 2024 to June 2025 and as Vice President of FP&A from January 2024 to October 2024. Mr. Graboske joined the Company as Chief Data Officer effective March 3, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5)Mr. Graboske's RSUs were modified and fully vested on December 22, 2025 pursuant to the Retention Compensation Arrangement entered into on December 14, 2025 between the Company and Mr. Graboske (the "Graboske Retention Agreement") that accelerates and fully vests Mr. Graboske's 2025 Inducement Equity Grant of 1,018,330 shares subject to the terms of the applicable equity plan and award agreement.

**Narrative Discussion of the Summary Compensation Table**

Definitive Healthcare's executive compensation philosophy is based on total direct compensation—base salary, annual cash incentives, and long-term equity incentives—designed to attract and retain executive talent, reward achievement of financial and strategic objectives, and align executives' interests with stockholders. The HCM & Compensation Committee oversees this program using its judgment, considers peer/market data and CEO recommendations (other than for the CEO), and generally seeks a mix in which long-term equity represents a substantial majority of target compensation.

------

**Base Salary**

The HCM & Compensation Committee reviews base salaries for our NEOs and considers the CEO's recommendations (for NEOs other than the CEO), each executive's role and responsibilities, and other factors such as competitive market data and individual performance.

The table below sets forth the base salaries for our NEOs in 2024 and 2025.

**Long-Term Equity Incentives**

The Company provides long-term equity incentives under the Definitive Healthcare Corp. 2021 Equity Incentive Plan to align the interests of eligible participants with stockholders by providing incentive compensation tied to Company performance. In determining long-term equity incentives for named executive officers, the HCM & Compensation Committee and Board have historically considered factors including corporate and individual performance, outstanding equity holdings and retention value, internal equity among executives, and market data provided by the independent compensation consultant.

For 2024 and 2025, the HCM & Compensation Committee granted equity awards to our NEOs in a mix of time-vesting RSUs and performance-vesting RSUs:

During the year ended December 31, 2025, Mr. Coop was granted 2,382,892 time-vesting RSUs and 1,283,096 performance-vesting RSUs, Ms. Heller was granted 984,220 time-vesting RSUs and 261,628 performance-vesting RSUs, and Mr. Graboske was granted 1,018,330 time-vesting RSUs. During the year ended December 31, 2024, Mr. Coop was granted 1,356,239 time-vesting RSUs and 1,137,038 performance-vesting RSUs and Ms. Heller was granted 115,513 time-vesting RSUs.

**Other Benefits/Perquisites**

Our NEOs participate in our employee benefit plans on the same basis as other employees, except that we pay the employee portion of medical, dental and vision premiums for our NEOs, and we generally do not provide other perquisites. Our NEOs are also eligible to participate in our 401(k) plan; for 2025, we provided matching contributions and did not make discretionary profit-sharing contributions. In connection with his appointment as EVP, Technology, Engineering and Chief Data Officer, we entered into an employment agreement with Mr. Benjamin Graboske (the "Offer Letter"). The Offer Letter provides for an initial base salary, annual performance bonus eligibility, an Inducement Award, participation in the Company's benefit plans, and a one-time signing bonus in cash, equal to $20,000 (the "Signing Bonus").

**Agreements with NEOs**

The vesting conditions and other terms and conditions applicable to, and the form of, the 2025 Annual Grant shall be determined by the Board and/or the HCM & Compensation Committee in its sole discretion and shall have an aggregate grant value (calculated in accordance with Parent's then-standard method of converting intended grant value into a number of shares) of at least $5,500,000. After 2025, the Executive shall be eligible to receive annual awards under the Equity Plan.

***Casey Heller***

As disclosed in our current report on Form 8-K, filed with the SEC on February 27, 2025, the Board of Directors appointed Casey Heller to the position of Chief Financial Officer ("CFO") effective June 2, 2025. On February 24, 2025, in connection with Ms. Heller's appointment as CFO, the Company entered into a promotion letter with Ms. Heller, dated as of February 24, 2025 (the "Heller Offer Letter"), which provided for, among other things, effective June 2, 2025, (i) an initial annual base salary of $375,000, (ii) a target bonus opportunity of 60% of her base salary, subject to the Company's Cash Incentive Plan for Executives (the "Cash Incentive Plan for Executives"), to be pro-rated to account for base salary and bonus opportunity applicable during 2025, (iii) certain severance benefits as set forth in the Heller Offer Letter, (iv) an award of time-vesting RSUs (the "Initial Promotion RSUs") with respect to the Company's Class A Common Stock, par value $0.001 per share (the "Class A Common Stock"), and (v) an award of RSUs (the "Annual RSUs") and performance-based restricted stock units ("PSUs") (the "Annual PSUs") consistent with annual equity awards issued to similarly-situated executives of the Company (together, the "Initial Annual Awards"). The Initial Promotion RSUs and the Initial Annual Awards will all be issued pursuant to the 2021 Plan.

The Initial Promotion RSUs will have a target value at grant of $1,500,000, and the number of RSUs subject to the Initial Promotion RSUs will be determined by dividing such grant value by the average closing price of a share of Common Stock for the thirty (30) trading days preceding (but not including) June 2, 2025, rounded up to the nearest whole share. The RSUs subject to the Initial Promotion RSUs will vest over two years with the first vest of 50% occurring on the first of the month on which the 1-year anniversary of the CFO start date falls (i.e., June 1, 2026), with the remaining shares vesting quarterly in approximately equal installments thereafter.

The Annual RSUs will have a target value at grant of $1,462,500 and the Annual PSUs will have a target value at grant of $787,500. The actual number of RSUs or PSUs (at target), as applicable, subject to the Initial Annual Awards, will be determined by dividing such estimated value by the average closing price of a share of Common Stock for the thirty (30) trading days preceding (but not including) the date of grant, rounded up to the nearest whole share. The Initial Annual Awards will be granted to Ms. Heller on the later of (a) the date on which 2025 annual equity awards are granted to other similarly situated executives; and (b) a date that is on or promptly following June 2, 2025. The Annual RSUs will vest over a four-year period with 25% vesting after 1 year and then quarterly vesting thereafter over the remaining 3 years. The Annual PSUs will be subject to, and will vest in accordance with, the terms of 2025 annual performance-based equity awards established by the Board or the HCM & Compensation Committee of the Board for issuance to other similarly-situated executive officers of the Company.

Pursuant to the Heller Offer Letter, she is entitled to certain severance benefits, as provided by the Company's Severance Plan for Executives, as modified by the terms of the Heller Offer Letter, and the Company's Change in Control Severance Plan for Executives.

If we terminate Ms. Heller's employment without cause (as defined in the Heller Offer Letter) and other than as a result of death or disability, or Ms. Heller terminates her employment for good reason (as defined in the Heller Offer Letter) then we must provide Ms. Heller with (i) continuation of regular payments of salary at the rate in effect on the date of termination for a period of twelve months from the date of termination of employment, payable in accordance with our regular payroll schedule; (ii) payment of any unpaid amount of the annual bonus for the immediately preceding calendar year that Ms. Heller would have earned in accordance with the Bonus Plan had the termination not occurred, plus an amount equal to the target annual bonus to be earned by Ms. Heller during the year in which the termination occurs, payable in a lump sum; (iii) acceleration of the vesting of all forms of time-based equity awarded to Ms. Heller by the Company at any time, that would otherwise have vested during the twelve-month period following the termination date, and (iv) payment for twelve months of COBRA coverage, if applicable.

Ms. Heller is eligible for reimbursement of certain expenses and will be entitled to participate in the Company's benefit plans that are generally available to the Company's executive employees. The Heller Offer Letter also entitles her to payment of up to $10,000 in legal fees in connection with the negotiation of the Heller Offer Letter.

Ms. Heller is eligible for reimbursement of certain expenses and is entitled to participate in the Company's benefit plans that are generally available to the Company's executive employees.

For a portion of 2025, the Company paid 100% of the health insurance premiums for Ms. Heller under the Company's sponsored health plans. Beginning in 2026, Ms. Heller is responsible for paying the employee portion of such health insurance premiums on the same basis as other employees of the Company.

**Benjamin Graboske** 

The Company entered into an employment arrangement with Mr. Graboske pursuant to an offer letter dated December 23, 2024, by and between the Company and Mr. Graboske (the "Graboske Offer Letter"), which became effective on March 3, 2025, at which time Mr. Graboske was appointed Executive Vice President, Technology and Engineering and Chief Data Officer. The Graboske Offer Letter provided for (i) an initial annual base salary of $385,000, (ii) a target bonus opportunity of 75% of his base salary, subject to the Cash Incentive Plan for Executives, to be pro-rated to account for base salary and bonus opportunity applicable during 2025, (iii) certain severance benefits as set forth in the Graboske Offer Letter, (iv) an Inducement Award (the "Award") RSUs valued at $5,000,000 with the actual number of RSUs to be determined by dividing such estimated grant value by the average closing price of a share of Common Stock for thirty (30) days preceding (but not including) the start date rounded up to the nearest whole share (iv) a $30,000 temporary housing allowance whereby the Company will reimburse for reasonable, documented, out of pocket relocation and temporary lodging expenses (the "Relocation Amount") and (v) a one-time Signing Bonus in cash, equal to $20,000 . Pursuant to the Graboske Offer Letter, he was entitled to certain severance benefits, as provided by the Company's Severance Plan for Executives, as modified by the terms of the Graboske Offer Letter, and the Company's Change in Control Severance Plan for Executives.

Mr. Graboske's RSU's were modified and fully vested on December 22, 2025 pursuant to the Graboske Retention Agreement.

Mr. Graboske was eligible for reimbursement of certain expenses and is entitled to participate in the Company's benefit plans that are generally available to the Company's executive employees.

For a portion of 2025, the Company paid 100% of the health insurance premiums for Mr. Graboske and his eligible dependents under the Company's sponsored health plans. Beginning in 2026, Mr. Graboske was responsible for paying the employee portion of such health insurance premiums on the same basis as other employees of the Company.

Mr. Graboske resigned as our EVP, Technology, Engineering and Chief Data Officer effective April 17, 2026.

**Equity Compensation** 

In connection with our IPO, we adopted the 2021 Plan, effective as of September 14, 2021. Additionally, our HCM & Compensation Committee approved the 2023 Inducement Plan on September 5, 2023 pursuant to Rule 5635(c)(4) of the Nasdaq Listing Rules. The terms of the 2023 Inducement Plan substantially mirror those of the 2021 Plan. The purpose of each of the 2021 Plan and 2023 Inducement Plan is to align the interests of eligible participants with our stockholders by providing incentive compensation tied to the Company's performance.

Prior to our IPO, we granted equity awards in the form of Class B Units ("Class B Units") under the AIDH Topco, LLC 2019 Equity Incentive Plan (the "2019 Plan"). In connection with the Reorganization Transactions (as defined below), unvested Class B Units held directly by employees of the Company or indirectly through AIDH Management Holdings, LLC were exchanged for (i) unvested LLC Units of AIDH Management Holdings, LLC (which correspond on a one-for-one basis to LLC Units in AIDH TopCo, LLC) or (ii) in the case of Mr. Krantz, unvested LLC Units in AIDH TopCo, LLC, in each such case based on their respective participation thresholds and the IPO price of $27.00 per share. All such unvested LLC Units are subject to time-based vesting. The Company no longer grants any awards under the 2019 Plan, though previously granted awards under the 2019 Plan remain outstanding and governed by the 2019 Plan. Until redeemed or exchanged, each LLC Unit is paired with one share of the Company's Class B Common Stock. Unless otherwise indicated or the context so requires, awards of "LLC Units" refer to LLC Units of AIDH TopCo held directly, in the case of Mr. Krantz, or indirectly through AIDH Management Holdings, LLC, in the case of our other directors and executive officers. For additional information with respect to the LLC Units, see "Certain Relationships and Related Person Transactions—Amended Definitive OpCo LLC Agreement" below.

(2)Calculated using the closing price of our Class A Common Stock on December 31, 2025 ($2.87).

(3)RSUs vested 25% on July 1, 2025, followed by quarterly vesting of 6.25% per quarter until fully vested, over the subsequent three years.

The PSUs will also be subject to a modifier (1.2x (at 75th percentile or greater), 1.0x (between 25th and 75th percentile) or 0.8x (below 25th percentile)), depending on the Company's TSR performance relative to the TSR performance of Nasdaq-listed companies classified under the Health Care Technology GICS Industry code during the performance period. Total payout, accounting for the TSR modifier, will not exceed 200% of target and, if our absolute TSR is negative over the performance period, the TSR modifier will be capped at 1.0x regardless of our relative TSR performance.

**Non-Employee Director Compensation Policy** 

Our non-employee directors receive cash and equity compensation for their service on the Board pursuant to our non-employee director compensation policy. Each non-employee director receives a $50,000 annual retainer for Board services. Our Audit Committee Chair and HCM & Compensation Committee Chair receive an additional chair retainer of $20,000, and our Nominating and Governance Committee Chair receives an additional chair retainer of $10,000, in each case to the extent such chair positions are held by eligible non-employee directors. All annual cash compensation is payable on a quarterly basis in arrears, and retainers are pro-rated for partial quarters of service. Each non-employee director also receives (i) an initial equity award of RSUs with a value of $300,000 upon joining our Board, and (ii) an annual equity award of RSUs, granted on the date of the annual meeting of stockholders, with a value of $175,000 (in the case of directors who join the Board following such date, granted upon appointment and pro-rated for the period from appointment through the one year anniversary of such annual meeting of stockholders), which vests upon the earlier to occur of the one-year anniversary of such annual meeting of stockholders and the date of the next year's annual meeting of stockholders, subject to such director's continued service.

Any director who is an employee of the Company and directors who are employees of Advent or Spectrum Equity do not receive compensation for services as a director or as a member of a committee of our Board.

**Director Stock Ownership Guidelines** 

Effective May 24, 2022, our HCM & Compensation Committee adopted stock ownership guidelines applicable to our non-employee directors (other than those directors who do not receive compensation for Board service because their principal employment is with an investment fund where such investment fund is an investor in the Company), which the HCM & Compensation Committee believes will help align the interests of our non-employee directors with those of our stockholders and may act as a risk mitigation device. Under these guidelines, our non-employee directors are each required to directly or indirectly own shares of our Common Stock (including shares owned outright, vested and unvested LLC Units, unvested shares of restricted stock or RSUs, and other shares that are considered beneficially owned by the director) with a value equal to at least three times their annual base cash retainer. Directors have five years from the later of the effective date of the guidelines or the date of commencement of their service on the Board to comply, and until the guidelines are satisfied, they must hold 25% of the shares received from their equity grants. As of our latest measurement date (December 31, 2025), all of our non-employee directors subject to the ownership guidelines had met or are on track to meet the required ownership guideline level for their tenure of service.

**SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT** 

The following table and accompanying footnotes set forth information regarding the beneficial ownership of our Common Stock as of April 1, 2026 by: (1) each person or group whom we know to beneficially own more than 5% of either class of our Common Stock; (2) each of the directors, director nominees, and NEOs individually; and (3) all of our directors and executive officers as a group.

The numbers of shares of our Class A Common Stock and Class B Common Stock beneficially owned, percentages of beneficial ownership of each such class and percentages of combined voting power as of April 1, 2026 that are set forth below are based on 105,456,979 shares of Class A Common Stock and 38,225,333 shares of Class B Common Stock issued and outstanding as of April 1, 2026. Our shares of Class B Common Stock have no economic rights, but each share entitles its holder to one vote on all matters on which our stockholders are entitled to vote generally.

In accordance with the rules of the SEC, beneficial ownership includes voting or investment power with respect to securities, and includes shares as to which there is a right to acquire ownership within 60 days following April 1, 2026. With respect to shares included due to ownership of restricted stock units or LLC Units scheduled to vest within such 60 day period, the underlying shares for which such restricted stock units would settle or for which such LLC Units would be exchangeable are deemed to be outstanding for the purpose of computing the percentage ownership of the person holding those restricted stock units or unvested LLC Units, but are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the address for each listed stockholder is: c/o Definitive Healthcare Corp., 492 Old Connecticut Path, Suite 401, Framingham, Massachusetts 01701. To our knowledge, except as indicated in the footnotes to this table and pursuant to applicable community property laws, the persons named in the table have sole voting and investment power with respect to all shares of Common Stock.

Generally, the pro rata amount to be distributed to each Unitholder is calculated based on the distribution to the Unitholder that would have the highest tax distribution on a per unit basis, with such calculated based on estimated net taxable income of Definitive OpCo allocable to the Unitholders and assumed tax rates equal to the highest effective marginal combined U.S. federal, state, and local income tax rate prescribed for an individual or corporate resident of New York, NY (whichever is higher) for the applicable year (taking into account the deductibility of state and local taxes to the extent applicable and the character of Definitive OpCo's income). As a result of (i) potential differences in the amount of taxable income allocable to us and the other Unitholders, (ii) the lower tax rate applicable to corporations than individuals, and (iii) the use of an assumed tax rate in calculating Definitive OpCo's distribution obligations, we may receive tax distributions significantly in excess of our tax liabilities and obligations to make payments under the Tax Receivable Agreement (as described below).

------

Except as otherwise determined by us and subject to certain exceptions, if at any time we issue a share of our Class A Common Stock, the net proceeds received by us with respect to such share, if any (less any amounts used to fund expenses or other obligations as to which we would be entitled to a distribution or reimbursement from Definitive OpCo), shall be concurrently contributed to Definitive OpCo and Definitive OpCo shall issue to us one LLC Unit, unless such share was issued by us solely to fund the purchase of an LLC Unit from a holder of LLC Units, in which case such net proceeds shall instead be transferred to the selling holder of LLC Units as consideration for such purchase and Definitive OpCo will not issue an additional LLC Unit to us. Similarly, except as otherwise determined by us, (i) Definitive OpCo will not issue any additional LLC Units to us unless we issue or sell an equal number of shares of our Class A Common Stock and (ii) should Definitive OpCo issue any additional LLC Units to any person other than us, we will issue an equal number of shares of our Class B Common Stock to such person (or, in the case of LLC Units corresponding to units of AIDH Management Holdings, LLC, to the holder of such units of AIDH Management Holdings, LLC). Conversely, if at any time any shares of our Class A Common Stock are purchased or otherwise acquired by us, Definitive OpCo will purchase or otherwise acquire an equal number of LLC Units held by us, upon the same terms and for the same price per security as the shares of our Class A Common Stock are purchased or otherwise acquired. In addition, except as otherwise determined by us, Definitive OpCo will not effect any subdivision (by any unit split, unit distribution, reclassification, reorganization, recapitalization, or otherwise) or combination (by reverse unit split, reclassification, reorganization, recapitalization, or otherwise) of the LLC Units unless it is accompanied by a substantively identical subdivision or combination, as applicable, of each class of our Common Stock (with corresponding changes made with respect to any other exchangeable or convertible securities), and conversely, we will not effect any subdivision or combination of any class of our Common Stock unless it is accompanied by a substantively identical subdivision or combination, as applicable, of the LLC Units.

Under our Amended LLC Agreement, Unitholders (other than us) have the right to require Definitive OpCo to redeem or exchange all or a portion of their vested LLC Units for newly-issued shares of Class A Common Stock, which may consist of unregistered shares, on a one-for-one basis (subject to customary adjustments, including for stock splits, stock dividends, and reclassifications), subject to certain exceptions. Upon the exercise of the redemption right, the exchanging member will surrender its LLC Units to Definitive OpCo for cancellation. The Amended LLC Agreement requires that we contribute shares of our Class A Common Stock to Definitive OpCo in exchange for an amount of newly-issued LLC Units in Definitive OpCo equal to the number of LLC Units exchanged from the surrendering holder of LLC Units. Definitive OpCo will then distribute the shares of our Class A Common Stock to such holder to complete the exchange. Alternatively, we may at our option effect the exchange in the form of a direct exchange of Class A Common Stock for LLC Units. Furthermore, in the event of an exchange request, we are obligated to ensure that at all times the number of LLC Units that we own equals the number of shares of Class A Common Stock issued by us (subject to certain exceptions for treasury shares and shares underlying certain convertible or exchangeable securities). Upon such an exchange, shares of Class B Common Stock held by the exchanging holder of LLC Units will be canceled on a one-for-one basis. Similarly, the holders of vested equity in AIDH Management Holdings, LLC have the right, pursuant to the terms of the amended and restated limited liability company agreement of AIDH Management Holdings, LLC, to cause Definitive OpCo or us to redeem or exchange (at our election) their vested equity for newly issued shares of Class A Common Stock on a one-for-one basis as though such holder were the direct member of Definitive OpCo pursuant to the terms of the Amended LLC Agreement. Upon such an exchange, shares of Class B Common Stock held by the exchanging holder of units of AIDH Management Holdings, LLC will be canceled on a one-for-one basis.

The Amended LLC Agreement provides that, in the event that a tender offer, share exchange offer, issuer bid, take-over bid, recapitalization, or similar transaction with respect to our Class A Common Stock is proposed by us or to us or our stockholders and approved by our Board of Directors or is otherwise effected or consented to or approved by our Board of Directors, holders of vested LLC Units other than us will be permitted to participate in such offer by delivery of a notice of exchange that is effective immediately prior to the consummation of such offer. In the case of any such offer proposed by us, we are obligated to use our reasonable best efforts to enable and permit such Unitholders to participate in such offer to the same extent or on an economically equivalent basis as the holders of shares of our Class A Common Stock without discrimination. In addition, we are obligated to use our reasonable best efforts to ensure that such Unitholders may participate in each such offer without being required to exchange LLC Units to the extent practicable.

The Amended LLC Agreement provides that, subject to certain exceptions, including transfers to us as provided above or to certain permitted transferees, the LLC Units and shares of Class B Common Stock may not be sold, transferred, or otherwise disposed of.

Subject to certain exceptions, Definitive OpCo will indemnify all of its members and their officers and certain other related parties against all losses or expenses arising from claims or other legal proceedings in which such person (in its capacity as such) may be involved or become subject to in connection with Definitive OpCo's business or affairs, the Amended LLC Agreement or any related document.

------

Definitive OpCo may be dissolved upon the earliest to occur of (i) 45 days after the sale or other disposition of all or substantially all of its assets, (ii) our approval of such a dissolution, (iii) the entry of a decree of dissolution, or (iv) such time as there are no remaining members, unless Definitive OpCo is continued in accordance with the Delaware Limited Liability Company Act. Upon dissolution, Definitive OpCo will be liquidated and the proceeds from any liquidation will be applied and distributed in the following manner: (a) first, to creditors (including creditors who are members or their respective affiliates that are creditors) in satisfaction of all of Definitive OpCo's liabilities (whether by payment or by making reasonable provision for payment of such liabilities, including the setting up of any reasonably necessary reserves) and (b) second, to the members in proportion to their vested LLC Units.

**Tax Receivable Agreement** 

In connection with the IPO, we entered into a Tax Receivable Agreement, or TRA, with the TRA Parties. Under the TRA, the Company generally will be required to pay to the TRA Parties 85% of the amount of cash savings, if any, in U.S. federal, state, or local tax that the Company actually realizes, or in certain circumstances is deemed to realize, directly or indirectly as a result of (i) certain tax attributes that the Company acquired from the Blocker Companies, (ii) certain tax basis adjustments resulting from (a) acquisitions by the Company of LLC Units from pre-IPO holders in connection with the IPO and (b) subsequent redemptions or exchanges of LLC Units by Unitholders of LLC Units for Class A Common Stock or other consideration, and (iii) certain payments made under the TRA. The Company expects to benefit from the remaining 15% of any tax benefits that it may actually realize. To the extent that the Company is unable to timely make payments under the TRA for any reason, such payments generally will be deferred and will accrue interest until paid.

We have recorded a tax receivable agreement liability of $27.2 million related to these benefits as of December 31, 2025. To the extent that the Company determines that it is able to realize the tax benefits associated with the basis adjustments and net operating losses, the Company would record an additional liability of $227.6 million, for a total liability of $254.8 million. The company made TRA payments during the year ended December 31, 2025 of $13.8 million.

**Nominating Agreements** 

We entered into nominating agreements, pursuant to which (a) Advent and its affiliates have the right, at any time until Advent no longer beneficially owns at least 21.5% of our outstanding Common Stock, to nominate two designees to our Board; and (b) so long as each of Spectrum Equity and Jason Krantz together with each of their respective affiliates, owns at least 5% of our outstanding Common Stock, respectively, Spectrum Equity and Jason Krantz, and their respective affiliates, each have the right to nominate one designee to our Board. After such time as Advent and its affiliates no longer beneficially own at least 21.5% of our outstanding Common Stock but so long as Advent and its affiliates are the beneficial owners of at least 5% of our Common Stock, Advent and its affiliates have the right to nominate one designee to our Board. So long as Advent, Spectrum Equity, and Jason Krantz together with their respective affiliates beneficially own at least 5% of our outstanding Common Stock, Advent, Spectrum Equity and Jason Krantz each have the right to nominate a designee to our Board to fill any vacancy of a director nominated by Advent, Spectrum Equity, or Jason Krantz, respectively, due to death, resignation, or removal. The nominating agreement with Spectrum Equity was terminated on April 6, 2026.

**Registration Rights Agreement** 

In connection with the IPO, we entered into a registration rights agreement with certain of the Unitholders and affiliates of Advent, affiliates of Spectrum Equity, Jason Krantz, and AIDH Management Holdings, LLC.

**Voting Agreement**

On November 7, 2024, the Company and Advent entered into a voting agreement, pursuant to which Advent agreed, on each matter brought to a vote at any annual or special meeting of the Company's stockholders and in connection with any action proposed to be taken by consent of the Company's stockholders in lieu of a meeting, to vote all shares of voting stock of the Company, or other voting or equity securities of the Company which could be issued (collectively, "Voting Securities") beneficially owned by Advent that exceed 40.3% of the outstanding Voting Securities of the Company as a result of the Company's stock repurchase program approved by the Board in November 2024 (the "Excess Voting Securities"), in the same proportion as all votes cast by stockholders other than Advent. Any Voting Securities that are not Excess Voting Securities may be voted at the discretion of Advent.

------

**Encora Agreement**

In November 2024, we entered into a master services agreement with Encora Digital, LLC ("Encora"), pursuant to which Encora provides staff augmentation to the Company's product and engineering departments, inclusive of design, development, and technical project management services and support. As of December 31, 2025, Advent, a holder of more than 5% of our voting securities, owns a majority voting interest in Encora Holdings, Inc., the parent company of Encora. Pursuant to the Encora master services agreement, we spent approximately $1.1 million in 2025 and expect to spend $1.3 million in 2026.

**Limitation of Directors' Liability and Indemnification Matters** 

Our Charter and Bylaws provide that we will indemnify our directors and officers, in each case, to the fullest extent permitted by Delaware law. Pursuant to our Charter, our directors will not be liable to us or any stockholders for monetary damages for any breach of fiduciary duty, except (i) for acts that breach his or her duty of loyalty to us or our stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, (iii) pursuant to Section 174 of the Delaware General Corporate Law (the "DGCL"), which provides for liability of directors for unlawful payments of dividends of unlawful stock purchase, or (iv) for any transaction from which the director derived an improper personal benefit. The Bylaws also require us, if so requested, to advance expenses that such director or officer incurred in defending or investigating a threatened or pending action, suit, or proceeding, provided that such person will return any such advance if it is ultimately determined that such person is not entitled to indemnification by us. We have entered into, and intend to continue to enter into, indemnification agreements with our directors and officers. We also maintain insurance on behalf of any person who is or was a director or officer of the Company against any loss arising from any claim asserted against him or her and incurred by him or her in any such capacity, subject to certain exclusions.

**Related Party Transactions Policies and Procedures** 

We have a Related Person Transaction Policy (the "Policy"), which sets forth our policy with respect to the review, approval, ratification, and disclosure of all related person transactions by our Audit Committee. In accordance with the policy, our Audit Committee has overall responsibility for implementation of and compliance with the policy.

For purposes of the Policy, subject to certain exceptions, a "related person transaction" is any transaction, arrangement, or relationship (or any series of similar transactions, arrangements, or relationships) in which the Company was, is or will be a participant, and in which any Related Person had, has or will have a direct or indirect material interest, and the amount involved exceeds the lesser of $120,000 or 1% of the average of our total assets at year-end for the last two completed fiscal years.

The Policy requires that notice of a proposed transaction or arrangement that could be a related person transaction be provided to our Chief Legal Officer, or his or her designee, the chair of the Board, or the chair of the Audit Committee prior to entry into such transaction. If it is determined that such transaction could be a related person transaction, the proposed transaction will be submitted to our Audit Committee for consideration at its next meeting or sooner if determined to be necessary by the Chief Legal Officer. Under the Policy, our Audit Committee may, in its discretion based upon a determination that such transactions are in the best interests of the Company and such other determinations as the Audit Committee deems appropriate, (i) approve or ratify such transactions, as applicable, (ii) request that the transaction be modified as a condition to the Audit Committee's approval or ratification, or (iii) reject and direct management to terminate or rescind the transaction.

**HOUSEHOLDING OF PROXY MATERIALS** 

Under rules adopted by the SEC, we are permitted to deliver a single Notice of Internet Availability of Proxy Materials and, if you requested printed versions by mail, this Proxy Statement and the Annual Report on Form 10-K for the year ended December 31, 2025, to any household in which two or more stockholders reside if we believe the stockholders are members of the same family. This process, called householding, allows us to reduce the number of copies of these materials we must print and mail. Even if householding is used, each stockholder will continue to be entitled to submit a separate proxy or voting instructions.

This year, we, or some brokers and nominees who hold Company shares on behalf of stockholders, may participate in the practice of householding proxy statements and annual reports for those stockholders. If your household receives a single Notice of Internet Availability of Proxy Materials for this year and, if you requested printed versions by mail, this Proxy Statement and the Annual Report on Form 10-K for the year ended December 31, 2025, but you would like to receive your own copy, please contact our Chief Legal Officer and Secretary, at Definitive Healthcare Corp., Chief Legal Officer, 492 Old Connecticut Path, Suite 401, Framingham, MA 01701, and we will promptly send you a copy. If a broker or nominee holds Company shares on your behalf and you share the same last name and address with another stockholder for whom a broker or nominee holds Company shares, and together both of you would like to receive only a single set of the Company's disclosure documents, please contact your broker or nominee as described in the voter instruction card or other information you received from your broker or nominee.

If you consent to householding, your election will remain in effect until you revoke it. Should you later revoke your consent, you will be sent separate copies of those documents that are mailed at least 30 days or more after receipt of your revocation.

**STOCKHOLDER PROPOSALS FOR THE 2027 ANNUAL MEETING** 

If any stockholder wishes to propose a matter for consideration at our 2027 Annual Meeting of Stockholders (the "2027 Annual Meeting"), the proposal should be mailed by certified mail return receipt requested, to our Chief Legal Officer and Secretary, Definitive Healthcare Corp., Chief Legal Officer, 492 Old Connecticut Path, Suite 401, Framingham, MA 01701. To be eligible under the SEC's stockholder proposal rule (Rule 14a-8(e) of the Exchange Act) for inclusion in our proxy statement for the 2027 Annual Meeting, a proposal must be received by our Secretary on or before December 24, 2027. Failure to deliver a proposal in accordance with this procedure may result in it not being deemed timely received.

In addition, our Bylaws permit stockholders to nominate candidates for director and present other business for consideration at our annual meeting of stockholders. To make a director nomination or present other business for consideration at the 2027 Annual Meeting, you must submit a timely notice in accordance with the procedures described in our Bylaws. To be timely, a stockholder's notice must be delivered to the Chief Legal Officer and Secretary at the principal executive offices of the Company not less than 90 days nor more than 120 days prior to the date of the first anniversary of the preceding year's annual meeting. Therefore, to be presented at our 2027 Annual Meeting, such a proposal must be received on or after February 5, 2027, but not later than March 7, 2027. In the event that the date of the 2027 Annual Meeting is more than 30 days before or more than 60 days after such anniversary date of this year's Annual Meeting, notice by the stockholder to be timely must be so delivered not earlier than the open of business on the 120th day prior to the 2027 Annual Meeting and not later than the close of business on the later of the 90th day prior to the 2027 Annual Meeting, or, if the first public announcement by the Company of the date of the 2027 Annual Meeting is less than 100 days prior to the 2027 Annual Meeting, the tenth day following the day on which public announcement of the date of the 2027 Annual Meeting is first made by the Company. Any such proposal will be considered timely only if it is otherwise in compliance with the requirements set forth in our Bylaws. In addition to satisfying the foregoing requirements under our Bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our Board of Director's Nominees must provide in their notice the additional information required by Rule 14a-19 under the Exchange Act.

------

**OTHER BUSINESS** 

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 will vote your shares in accordance with their best judgment. This discretionary authority is granted by the execution of the form of proxy.

The Committee shall, in its discretion, consider such factors as it deems relevant in making its interpretations, determinations and actions under the Plan including, without limitation, the recommendations or advice of any officer or employee of the Company or board of directors of a Subsidiary or such attorneys, consultants, accountants or other advisors as it may select. All interpretations, determinations, and actions by the Committee shall be final, conclusive, and binding upon all parties.

*Delegation of Authority*.

The Committee shall also be permitted to delegate, to any appropriate officer or employee of the Company, responsibility for performing certain ministerial functions under the Plan. In the event that the Committee's authority is delegated to officers or employees in accordance with the foregoing, all provisions of the Plan relating to the Committee shall be interpreted in a manner consistent with the foregoing by treating any such reference as a reference to such officer or employee for such purpose. Any action undertaken in accordance with the Committee's delegation of authority hereunder shall have the same force and effect as if such action was undertaken directly by the Committee and shall be deemed for all purposes of the Plan to have been taken by the Committee.

<u>Shares Subject to the Plan</u>.

*Number of Shares Reserved*. Subject to adjustment as provided in Section 4.3 and Section 4.5 hereof, the total number of shares of Common Stock that are available for issuance under the Plan (the "Share Reserve") shall equal 33,989,039. Within the Share Reserve, the total number of shares of Common Stock available for issuance as Incentive Stock Options shall equal the maximum number of shares available for issuance under the Plan. Each share of Common Stock subject to an Award shall reduce the Share Reserve by one share. Any shares of Common Stock delivered under the Plan shall consist of authorized and unissued shares or treasury shares.

*Annual Increase in Shares Reserved*. On the first day of each fiscal year of the Company during the term of the Plan, commencing on January 1, 2023 and ending on (and including) January 1, 2032, the aggregate number of shares of Common Stock that may be issued under the Plan shall automatically increase by a number equal to the least of (i) 5% of the total number of shares

------

of Common Stock actually issued and outstanding on the last day of the preceding fiscal year, (ii) a number of shares of Common Stock determined by the Board; and (iii) 8,989,039 shares of Common Stock.

*Share Replenishment*. Following the Effective Date, to the extent that an Award granted under this Plan is canceled, expired, repurchased, forfeited, surrendered, exchanged for cash, settled in cash or by delivery of fewer shares of Common Stock than the number underlying the Award, or otherwise terminated without delivery of the shares of Common Stock to the Participant under the Plan, the unissued shares of Common Stock will (i) not be deemed to have been delivered under the Plan, (ii) be available for future Awards under the Plan, and (iii) increase the Share Reserve by one share for each share that is retained by or returned to the Company. Shares of Common Stock that are withheld from any Award granted under this Plan in payment of the exercise, base or purchase price or taxes relating to such an Award shall be available for future Awards under the Plan, and shall increase the Share Reserve by one share for each share that is retained by or returned to the Company. Shares of Common Stock repurchased by the Company on the open market with the proceeds of an Option, will be deemed to have been delivered under the Plan and will not be available for future Awards under the Plan.

If the vesting requirements of a Stock Option are not satisfied. the Award shall be forfeited.

*Term of Stock Options*. The Committee shall in its discretion prescribe in an Award Agreement the period during which a vested Stock Option may be exercised; <u>provided</u>, <u>however</u>, that the maximum term of a Stock Option shall be ten (10) years from the Date of Grant. If the Fair Market Value of a share of Common Stock exceeds the Exercise Price on the last day that the Stock Option may be exercised under an Award Agreement. the affected Participant shall be deemed to have exercised the vested portion of such Option in a net exercise under Section 6.5(ii)(C) below and net share withholding for taxes (unless otherwise agreed) without the requirement of any further action.

------

*Annual Limits*. No Incentive Stock Option shall be granted to a Participant as a result of which the aggregate Fair Market Value (determined as of the Date of Grant) of the Common Stock with respect to which incentive stock options under Section 422 of the Code are exercisable for the first time in any calendar year under the Plan and any other stock option plans of the Company or any Subsidiary or parent corporation, would exceed $100,000, determined in accordance with Section 422(d) of the Code. This limitation shall be applied by taking Stock Options into account in the order in which granted. Any Stock Option grant that exceeds such limit shall be treated as a Non9ualified Stock Option.

*Additional Limitations*. In the case of any Incentive Stock Option granted to an Eligible Person who owns, either directly or indirectly (taking into account the attribution rules contained in Section 424(d) of the Code), stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Subsidiary, the exercise price shall not be less than one hundred ten percent (110%) of the Fair Market Value of a share of Common Stock on the Date of Grant and the maximum term shall be five (5) years.

A Stock Option that is granted as an Incentive Stock Option shall, to the extent it fails to 9ualify as an "incentive stock option" under the Code, be treated as a Non9ualified Stock Option. An Incentive Stock Option shall by its terms be nontransferable other than by will or by the laws of descent and distribution, and shall be exercisable during the lifetime of a Participant only by such Participant.

*Disqualifying Dispositions*. If shares of Common Stock ac9uired by exercise of an Incentive Stock Option are disposed of within two years following the Date of Grant or one year following the transfer of such shares to the Participant upon exercise, the Participant shall, promptly following such disposition, notify the Company in writing of the date and terms of such disposition and provide such other information regarding the disposition as the Company may reasonably re9uire.

Subject to the adjustment provisions contained in Section 4.5 hereof and other than in connection with a Change in Control, without the prior approval of the Company's stockholders, neither the Committee nor the Board shall cancel a Stock Option when the exercise price per share exceeds the Fair Market Value of one share of Common Stock in exchange for cash or another Award or cause the cancellation, substitution or amendment of a Stock Option that would have the effect of reducing the exercise price of such a Stock Option previously granted under the Plan or otherwise approve any modification to such a Stock Option, that would be treated as a "repricing" under the then applicable rules, regulations or listing requirements adopted by the NASDAQ or other principal exchange on which the Common Stock is then listed.

*No Rights as Stockholder*. The Participant shall not have any rights as a stockholder with respect to the shares underlying a Stock Option until such time as shares or Common Stock are delivered to the Participant pursuant to the terms of the Award Agreement.

<u>Stock Appreciation Rights</u>.

All Stock Appreciation Rights granted under the Plan are intended to comply with or otherwise be exempt from the requirements of Section 409A of the Code, to the extent applicable.

*Terms of Stock Appreciation Rights*. The Committee shall in its discretion provide in an Award Agreement the time or times at which or the conditions upon which, a Stock Appreciation Right or portion thereof shall become vested and/or exercisable. If the Fair Market Value of a share of Common Stock exceeds the base price on the last day that the Stock Appreciation Right may be exercised under an Award Agreement, the affected Participant shall be deemed to have exercised the vested portion of such Stock Appreciation Right and net share withholding for taxes (unless otherwise agreed) without the requirement of any further action. The requirements for vesting and exercisability of a Stock Appreciation Right may be based on the continued Service of a

------

Participant with the Company or a Subsidiary for a specified time period (or periods), on the attainment of a specified performance goal(s) and/or on such other terms and conditions as approved by the Committee in its discretion. If the vesting requirements of a Stock Appreciation Right are not satisfied, the Award shall be forfeited. A Stock Appreciation Right will be exercisable or payable at such time or times as determined by the Committee; <u>provided</u>, <u>however</u>, that the maximum term of a Stock Appreciation Right shall be ten (10) years from the Date of Grant.

The Committee may provide that a Stock Appreciation Right will cease to be exercisable upon or at the end of a period following a termination of Service for any reason. The base price of a Stock Appreciation Right shall be determined by the Committee in its discretion; <u>provided</u>, <u>however</u>, that the base price per share shall not be less than one hundred percent (100%) of the Fair Market Value of a share of Common Stock on the Date of Grant (other than with respect to a Stock Appreciation Right substituted or assumed under Section 14.10).

A Stock Appreciation Right will entitle the holder, upon exercise or other payment of the Stock Appreciation Right, as applicable, to receive an amount determined by multiplying: (i) the excess of the Fair Market Value of a share of Common Stock on the date of exercise or payment of the Stock Appreciation Right over the base price of such Stock Appreciation Right, by (ii) the number of shares as to which such Stock Appreciation Right is exercised or paid. Payment of the amount determined under the foregoing may be made, as approved by the Committee and set forth in the Award Agreement, in shares of Common Stock valued at their Fair Market Value on the date of exercise or payment, in cash or in a combination of shares of Common Stock and cash, subject to applicable tax withholding requirements.

The requirements for vesting of a Restricted Stock Award may be based on the continued Service of the Participant with the Company or a Subsidiary for a specified time period (or periods), on the attainment of a specified performance goal(s) and/or on such other terms and conditions as approved by the Committee in its discretion.

*Transfer Restrictions*. Shares granted under any Restricted Stock Award may not be transferred, assigned or subject to any encumbrance, pledge or charge until all applicable restrictions are removed or have expired, except as provided in Section 14.3 hereof. Failure to satisfy any applicable restrictions shall result in the subject shares of the Restricted Stock being forfeited and returned to the Company. The Committee may require in an Award Agreement that certificates (if any) representing the shares granted under a Restricted Stock Award bear a legend making appropriate reference to the restrictions imposed, and that certificates (if any) representing the shares granted or sold under a Restricted Stock Award will remain in the physical custody of an escrow holder until all restrictions are removed or have expired.

<u>Change in Control</u>.

*Effect on Awards*. Upon the occurrence of a Change in Control, all outstanding Awards shall either be (a) continued or assumed by the Company (if it is the surviving company or corporation) or by the surviving company or corporation or its parent (with such continuation or assumption including conversion into the right to receive securities, cash or a combination of both), or (b) substituted by the surviving company or corporation or its parent for awards (with such substitution including conversion into the right to receive securities, cash or a combination of both), with substantially similar terms for outstanding Awards (with appropriate adjustments to the type of consideration payable upon settlement of the Awards or other relevant factors, and with any applicable performance conditions deemed achieved (i) for any completed performance period, based on actual performance, or (ii) for any partial or future performance period, at the greater of the target level or actual performance, in each case as determined by the Committee (with the Award remaining subject only to time vesting), unless otherwise provided in an Award Agreement).

*Certain Adjustments*. Notwithstanding Section 11.1, to the extent that outstanding Awards are not continued, assumed or substituted pursuant to Section 11.1 upon the occurrence of a Change in Control, the Committee is authorized (but not obligated) to make adjustments in the terms and conditions of outstanding Awards, including without limitation the following (or any combination thereof):

acceleration of exercisability, vesting and/or payment of outstanding Awards immediately prior to the occurrence of such event or upon or following such event;

upon written notice, providing that any outstanding Stock Options and Stock Appreciation Rights are exercisable during a period of time immediately prior to the scheduled consummation of the event or such other period as determined by the Committee (contingent upon the consummation of the event), and at the end of such period, such Stock Options and Stock Appreciation Rights shall terminate to the extent not so exercised within the relevant period; and

cancellation of all or any portion of outstanding Awards for fair value (in the form of cash, Common Shares, other property or any combination thereof) as determined in the sole discretion of the Committee; provided, however, that, in the case of Stock Options and Stock Appreciation Rights or similar Awards, the fair value may equal the excess, if any, of the value or amount of the consideration to be paid in the Change in Control transaction to holders of shares of Common Stock (or, if no such consideration is paid, Fair Market Value of the shares of Common Stock) over the aggregate exercise or base price, as applicable, with respect to such Awards or portion thereof being canceled, or if there is no such excess, zero; provided, <u>further</u>, that if any payments or other consideration are deferred and/or contingent as a result of escrows, earn outs, holdbacks or any other contingencies, payments under this provision may be made on substantially the same terms and conditions applicable to, and only to the extent actually paid to, the holders of Common Shares in connection with the Change in Control.

*Certain Terminations of Service*. Notwithstanding the provisions of Section 11.1, if a Participant's Service with the Company and its Subsidiaries is terminated upon or within twenty four (24) months following a Change in Control by the Company without Cause or upon such other circumstances as determined by the Committee, the unvested portion (if any) of all outstanding Awards held by the Participant shall immediately vest (and, to the extent applicable, become exercisable) and be paid in full upon such termination, with any applicable performance conditions deemed achieved (i) for any completed performance period, based on actual performance, or (ii) for any partial or future performance period, at the greater of the target level or actual performance, in each case as determined by the Committee, unless otherwise provided in an Award Agreement.

*Definition of Change in Control*. Unless otherwise defined in an Award Agreement or other written agreement approved by the Committee "Change in Control" means and shall occur if:

any Person (other than the Company, any trustee or other fiduciary holding securities under any employee benefit plan of the Company, or any company owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of shares of Common Stock), is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing more than 50% of the combined voting power of the Company's then outstanding securities;

during any period of two consecutive years (the "Board Measurement Period") individuals who at the beginning of such period constitute the Board and any new director (other than a director designated by a Person who has entered into an agreement with the Company to effect a transaction described in paragraph (a), (c), or (d) of this section, or a director initially elected or nominated as a result of an actual or threatened election contest with respect to directors or as a result of any other actual or threatened solicitation of pro7ies by or on behalf of any Person other than the Board) whose election by the Board or nomination for election by the Company's stockholders was approved by a vote of at least two-thirds of the directors then still in office who

------

either were directors at the beginning of the Board Measurement Period or whose election or nomination for election was previously so approved, cease for any reason to constitute at least a majority of the Board;

a merger or consolidation of the Company with any other corporation, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than 50% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; provided, however, that a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no Person (other than those covered by the exceptions in (i) above) acquires more than 50% of the combined voting power of the Company's then outstanding securities shall not constitute a Change in Control of the Company; or

the stockholders of the Company approve the consummation of the sale or disposition by the Company of all or substantially all of the Company's assets other than (i) the sale or disposition of all or substantially all of the assets of the Company to a Person or Persons who beneficially own, directly or indirectly, more than 50% of the combined voting power of the outstanding voting securities of the Company at the time of the sale or disposition or (ii) pursuant to a spinoff type transaction, directly or indirectly, of such assets to the stockholders of the Company.

Notwithstanding the foregoing, to the extent necessary to comply with Section 409A of the Code with respect to the payment of "nonqualified deferred compensation," "Change in Control" shall be limited to a "change in control event" as defined under Section 409A of the Code.

<u>Forfeiture Events</u>.

*General.* The Committee may specify in an Award Agreement that the Participant's rights, payments and benefits with respect to an Award are subject to reduction, cancellation, forfeiture or recoupment upon the occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. Such events may include, without limitation, termination of Service for Cause, violation of laws, regulations or material Company policies, breach of noncompetition, non-solicitation, confidentiality or other restrictive covenants that may app(y to the Participant, application of a Company clawback policy relating to financial restatement, or other conduct by the Participant that is detrimental to the business or reputation of the Company.

*Termination for Cause*.

*Treatment of Awards*. Unless otherwise provided by the Committee and set forth in an Award Agreement, if (i) a Participant's Service with the Company or any Subsidiary shall be terminated for Cause or (ii) after termination of Service for any other reason, the Committee determines in its discretion either that, (1) during the Participant's period of Service, the Participant engaged in an act or omission which would have warranted termination of Service for Cause or (2) after termination, the Participant engages in conduct that violates any continuing obligation or duty of the Participant in respect of the Company or any Subsidiary, such Participant's rights, payments and benefits with respect to an Award shall be subject to cancellation, forfeiture and/or recoupment, as provided in Section 12.3 below. The Company shall have the power to determine whether the Participant has been terminated for Cause, the date upon which such termination for Cause occurs, whether the Participant engaged in an act or omission which would have warranted termination of Service for Cause or engaged in conduct that violated any continuing obligation or duty of the Participant in respect of the Company or any Subsidiary. Any such determination shall be final, conclusive and binding upon all Persons. In addition, if the Company shall reasonably determine that a Participant has committed or may have committed any act which could constitute the basis for a termination of such Participant's Service for Cause or violates any continuing obligation or duty of the Participant in respect of the Company or any Subsidiary, the Company may suspend the Participant's rights to exercise any Stock Option or Stock Appreciation Right, receive any payment or vest in any right with respect to any Award pending a determination by the Company of whether an act or omission could constitute the basis for a termination for Cause as provided in this Section 12.2.

*Definition of Cause*. "Cause" means with respect to a Participant's termination of Service, the following: (a) in the case where there is no employment agreement, consulting agreement, change in control agreement or similar agreement in effect between the Company or an Affiliate and the Participant (or where there is such an agreement but it does not define "cause" (or words of like import, which shall include but not be limited to "gross misconduct")), termination due to a Participant's (1) failure to substantially perform Participant's duties or obey lawful directives that continues after receipt of written notice from the Company and a 10-day opportunity to cure; (2) gross misconduct or gross negligence in the performance of Participant's duties; (3) fraud, embezzlement, theft, or any other act of material dishonesty or misconduct; (4) conviction of, indictment for, or plea of guilty or nolo contendere to, a felony or any crime involving moral turpitude; (5) material breach or violation of any agreement with the Company or its Affiliates, any restrictive covenant applicable to Participant, or any Company policy (including, without

------

limitation, with respect to harassment); or (6) other conduct, acts or omissions that, in the good faith judgment of the Company, are likely to materially injure the reputation, business or a business relationship of the Company or any of its Affiliates; or (b) in the case where there is an employment agreement, consulting agreement, change in control agreement or similar agreement in effect between the Company or an Affiliate and the Participant that defines "cause" (or words of like import, which shall include but not be limited to "gross misconduct"), "cause" as defined under such agreement. With respect to a termination of Service for a non-employee director, Cause means an act or failure to act that constitutes cause for removal of a director under applicable law. Any voluntary termination of Service by the Participant in anticipation of an involuntary termination of the Participant's Service for Cause shall be deemed to be a termination for Cause.

*Right of Recapture*.

*General*. If at any time within one year (or such longer time specified in an Award Agreement or other agreement with a Participant or policy applicable to the Participant) after the date on which a Participant exercises a Stock Option or Stock Appreciation Right or on which a Stock-Based Award, Restricted Stock Award or Restricted Stock Unit vests, is settled in shares or otherwise becomes payable, or on which income otherwise is realized or property is received by a Participant in connection with an Award, (i) a Participant's Service is terminated for Cause, (ii) the Committee determines in its discretion that the Participant is subject to any recoupment of benefits pursuant to the Company's compensation recovery, "clawback" or similar policy, as may be in effect from time to time, or (iii) after a Participant's Service terminates for any other reason, the Committee determines in its discretion either that, (1) during the Participant's period of Service, the Participant engaged in an act or omission which would have warranted termination of the Participant's Service for Cause or (2) after a Participant's termination of Service, the Participant engaged in conduct that violated any continuing obligation or duty of the Participant in respect of the Company or any Subsidiary, then, at the sole discretion of the Committee, any gain realized by the Participant from the exercise, vesting, payment, settlement or other realization of income or receipt of property by the Participant in connection with an Award, shall be repaid by the Participant to the Company upon notice from the Company, subject to applicable law. Such gain shall be determined as of the date or dates on which the gain is realized by the Participant, without regard to any subsequent change in the Fair Market Value of a share of Common Stock. To the extent not otherwise prohibited by law, the Company shall have the right to offset the amount of such repayment obligation against any amounts otherwise owed to the Participant by the Company (whether as wages, vacation pay or pursuant to any benefit plan or other compensatory arrangement).

*Accounting Restatement*. If a Participant receives compensation pursuant to an Award under the Plan based on financial statements that are subsequently restated in a way that would decrease the value of such compensation, the Participant will, to the extent not otherwise prohibited by law, upon the written request of the Company, forfeit and repay to the Company the difference between what the Participant received and what the Participant should have received based on the accounting restatement, in accordance with (i) any compensation recovery, "clawback" or similar policy, as may be in effect from time to time to which such Participant is subject and (ii) any compensation recovery, "clawback" or similar policy made applicable by law including the provisions of Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the rules, regulations and requirements adopted thereunder by the Securities and Exchange Commission and/or any national securities exchange on which the Company's equity securities may be listed (the "Policy"). By accepting an Award hereunder, the Participant acknowledges and agrees that the Policy, whenever adopted, shall apply to such Award, and all incentive-based compensation payable pursuant to such Award shall be subject to forfeiture and repayment pursuant to the terms of the Policy.

<u>Transfer, Leave of Absence, Etc</u>. For purposes of the Plan, except as otherwise determined by the Committee, the following events shall not be deemed a termination of Service: (a) a transfer to the service of the Company from a Subsidiary or from the Company to a Subsidiary, or from one Subsidiary to another; or (b) an approved leave of absence for military service or sickness, a leave of absence where the employees right to re-employment is protected either by a statute or by contract or under the policy pursuant to which the leave of absence was granted, a leave of absence for any other purpose approved by the Company or if the Committee otherwise so provides in writing.

*General Provisions*.

*Status of Plan*. The Committee may authorize the creation of trusts or other arrangements to meet the Company's obligations to deliver shares of Common Stock or make payments with respect to Awards.

*Award Agreement*. An Award under the Plan shall be evidenced by an Award Agreement in a written or electronic form approved by the Committee setting forth the number of shares of Common Stock or other amounts or securities subject to the Award, the exercise price, base price or purchase price of the Award, the time or times at which an Award will become vested, exercisable or payable and the term of the Award. The Award Agreement also may set forth the effect on an Award of a Change in Control and/or a termination of Service under certain circumstances. The Award Agreement shall be subject to and incorporate, by reference or otherwise, all of the applicable terms and conditions of the Plan, and also may set forth other terms and conditions

------

applicable to the Award as determined by the Committee consistent with the limitations of the Plan. The grant of an Award under the Plan shall not confer any rights upon the Participant holding such Award other than such terms, and subject to such conditions, as are specified in the Plan as being applicable to such type of Award (or to all Awards) or as are expressly set forth in the Award Agreement. The Committee need not require the execution of an Award Agreement by a Participant, in which case, acceptance of the Award by the Participant shall constitute agreement by the Participant to the terms, conditions, restrictions and limitations set forth in the Plan and the Award Agreement as well as the administrative guidelines of the Company in effect from time to time. In the event of any conflict between the provisions of the Plan and any Award Agreement, the provisions of the Plan shall prevail.

*No Assignment or Transfer; Beneficiaries*. Except as provided in Section 6.6 hereof or as otherwise provided by the Committee to the extent not prohibited under Section A.1.(5) of the general instructions of Form S-8, as may be amended from time to time, Awards under the Plan shall not be assignable or transferable by the Participant, and shall not be subject in any manner to assignment, alienation, pledge, encumbrance or charge. Notwithstanding the foregoing, in the event of the death of a Participant, except as otherwise provided by the Committee, an outstanding Award may be exercised by or shall become payable to the Participant's beneficiary as determined under the Company 401(k) retirement plan or other applicable retirement or pension plan. In lieu of such determination, a Participant may, from time to time, name any beneficiary or beneficiaries to receive any benefit in case of the Participant's death before the Participant receives any or all of such benefit. Each such designation shall revoke all prior designations by the same Participant and will be effective only when filed by the Participant in writing (in such form or manner as may be prescribed by the Committee) with the Company during the Participant's lifetime. In the absence of a valid designation as provided above, if no validly designated beneficiary survives the Participant or if each surviving validly designated beneficiary is legally impaired or prohibited from receiving the benefits under an Award, the Participant's beneficiary shall be the legatee or legatees of such Award designated under the Participant's last will or by such Participant's executors, personal representatives or distributees of such Award in accordance with the Participant's will or the laws of descent and distribution. The Committee may provide in the terms of an Award Agreement or in any other manner prescribed by the Committee that the Participant shall have the right to designate a beneficiary or beneficiaries who shall be entitled to any rights, payments or other benefits specified under an Award following the Participant's death. Any transfer permitted under this Section 14.3 shall be for no consideration.

*No Right to Employment or Continued Service*. Nothing in the Plan, in the grant of any Award or in any Award Agreement shall confer upon any Eligible Person or any Participant any right to continue in the Service of the Company or any of its Subsidiaries or interfere in any way with the right of the Company or any of its Subsidiaries to terminate the employment or other service relationship of an Eligible Person or a Participant for any reason or no reason at any time.

*Rights as Stockholder*. A Participant shall have no rights as a holder of shares of Common Stock with respect to any unissued securities covered by an Award until the date the Participant becomes the holder of record of such securities. Except as provided in Section 4.5 hereof, no adjustment or other provision shall be made for dividends or other stockholder rights, except to the extent that the Award Agreement provides for dividend payments or dividend equivalent rights. The Committee may determine in its discretion the manner of delivery of Common Stock to be issued under the Plan, which may be by delivery of stock certificates, electronic account entry into new or existing accounts or any other means as the Committee, in its discretion, deems appropriate. The Committee may require that the stock certificates (if any) be held in escrow by the Company for any shares of Common Stock or cause the shares to be legended in order to comply with the securities laws or other applicable restrictions. Should the shares of Common Stock be represented by book or electronic account entry rather than a certificate, the Committee may take such steps to restrict transfer of the shares of Common Stock as the Committee considers necessary or advisable.

*Trading Policy and Other Restrictions*. Transactions involving Awards under the Plan shall be subject to the Company's insider trading and other restrictions, terms, conditions and policies, established by the Committee from time to time or by applicable law.

*Section 409A Compliance*. To the extent applicable, it is intended that the Plan and all Awards hereunder comply with, or be exempt from, the requirements of Section 409A of the Code and the Treasury Regulations and other guidance issued thereunder, and that the Plan and all Award Agreements shall be interpreted and applied by the Committee in a manner consistent with this intent in order to avoid the imposition of any additional tax under Section 409A of the Code. In the event that any (i) provision of the Plan or an Award Agreement, (ii) Award, payment, transaction or (iii) other action or arrangement contemplated by the provisions of the Plan is determined by the Committee to not comply with the applicable requirements of Section 409A of the Code and the Treasury Regulations and other guidance issued thereunder, the Committee shall have the authority to take such actions and to make such changes to the Plan or an Award Agreement as the Committee deems necessary to comply with such requirements. No payment that constitutes deferred compensation under Section 409A of the Code that would otherwise be made under the Plan or an Award Agreement upon a termination of Service will be made or provided unless and until such termination is also a "separation from service," as determined in accordance with Section 409A of the Code. Notwithstanding the foregoing or anything elsewhere in the Plan or an Award Agreement to the contrary, if a Participant is a "specified employee" as defined in Section 409A of the Code at the time of termination of Service with respect to an Award, then solely to the extent necessary to avoid the imposition

------

of any additional tax under Section 409A of the Code, the commencement of any payments or benefits under the Award shall be deferred until the date that is six (6) months plus one (1) day following the date of the Participant's termination of Service or, if earlier, the Participant's death (or such other period as required to comply with Section 409A). For purposes of Section 409A of the Code, a Participant's right to receive any installment payments pursuant to this Plan or any Award granted hereunder shall be treated as a right to receive a series of separate and distinct payments. For the avoidance of doubt, each applicable tranche of Common Shares subject to vesting under any Award shall be considered a right to receive a series of separate and distinct payments. In no event whatsoever shall the Company be liable for any additional tax, interest or penalties that may be imposed on a Participant by Section 409A of the Code or any damages for failing to comply with Section 409A of the Code.

*Section 457A Compliance*. In the event any Award is subject to Section 457A of the Code ("Section 457A"), the Committee may, in its sole discretion and without a Participant's prior consent, amend the Plan and/or Awards, adopt policies and procedures, or take any other actions (including amendments, policies, procedures and actions with retroactive effect) as are necessary or appropriate to (i) exempt the Plan and/or any Award from the application of Section 457A, (ii) preserve the intended tax treatment of any such Award, or (iii) comply with the requirements of Section 457A, including without limitation any such regulations, guidance, compliance programs and other interpretative authority that may be issued after the date of the grant. To the extent that an Award constitutes deferred compensation subject to Section 457A, such Award will be subject to taxation in accordance with Section 457A. In no event whatsoever shall the Company be liable for any additional tax, interest or penalties that may be imposed on a Participant by Section 457A of the Code or any damages for failing to comply with Section 457A of the Code.

*Securities Law Compliance*. No shares of Common Stock will be issued or transferred pursuant to an Award unless and until all then applicable requirements imposed by Federal and state securities and other laws, rules and regulations and by any regulatory agencies having jurisdiction, and by any exchanges upon which the shares of Common Stock may be listed, have been fully met. As a condition precedent to the issuance of shares of Common Stock pursuant to the grant or exercise of an Award, the Company may require the Participant to take any action that the Company determines is necessary or advisable to meet such requirements. The Committee may impose such conditions on any shares of Common Stock issuable under the Plan as it may deem advisable, including, without limitation, restrictions under the Securities Act, under the requirements of any exchange upon which such shares of the same class are then listed, and under any blue sky or other securities laws applicable to such shares. The Committee may also require the Participant to represent and warrant at the time of issuance or transfer that the shares of Common Stock are being acquired solely for investment purposes and without any current intention to sell or distribute such shares.

*Substitution or Assumption of Awards in Corporate Transactions*. The Committee may grant Awards under the Plan in connection with the acquisition, whether by purchase, merger, consolidation or other corporate transaction, of the business or assets of any corporation or other entity, in substitution for awards previously granted by such corporation or other entity or otherwise. The Committee may also assume any previously granted awards of a former employee or a current employee, director, consultant or other service provider of another corporation or entity that becomes an Eligible Person by reason of such corporation transaction. The terms and conditions of the substituted or assumed awards may vary from the terms and conditions that would otherwise be required by the Plan solely to the extent the Committee deems necessary for such purpose. To the extent permitted by applicable law and the listing requirements of the NASDAQ or other exchange or securities market on which the Common Shares are listed, any such substituted or assumed awards shall not reduce the Share Reserve.

*Tax Withholding*. The Participant shall be responsible for payment of any taxes or similar charges required by law to be paid or withheld from an Award or an amount paid in satisfaction of an Award. Any required withholdings shall be paid by the Participant on or prior to the payment or other event that results in taxable income in respect of an Award. The Award Agreement may specify the manner in which the withholding obligation shall be satisfied with respect to the particular type of Award, which may include permitting the Participant to elect to satisfy the withholding obligation by tendering shares of Common Stock to the Company or having the Company withhold a number of shares of Common Stock having a value in each case up to the maximum statutory tax rates in the applicable jurisdiction or as the Committee may approve in its discretion (provided that such withholding does not result in adverse tax or accounting consequences to the Company), or similar charge required to be paid or withheld. In addition, to the extent permitted by the Committee in its sole discretion in an Award Agreement or otherwise, and subject to Section 16 of the Securities Act, withholding may be satisfied through an open-market, broker-assisted sales transaction pursuant to which the Company is promptly delivered the amount of proceeds necessary to satisfy the withholding amount, which shall be subject to any terms and conditions imposed by the Committee. The Company shall have the power and the right to require a Participant to remit to the Company the amount necessary to satisfy federal, state, provincial and local taxes, domestic or foreign, required by law or regulation to be withheld, and to deduct or withhold from any shares of Common Stock deliverable under an Award to satisfy such withholding obligation.

*Unfunded Plan*. The adoption of the Plan and any reservation of shares of Common Stock or cash amounts by the Company to discharge its obligations hereunder shall not be deemed to create a trust or other funded arrangement. Except upon the issuance of shares of Common Stock pursuant to an Award, any rights of a Participant under the Plan shall be those of a general unsecured

------

creditor of the Company, and neither a Participant nor the Participant's permitted transferees or estate shall have any other interest in any assets of the Company by virtue of the Plan. Notwithstanding the foregoing, the Company shall have the right to implement or set aside funds in a grantor trust, subject to the claims of the Company's creditors or otherwise, to discharge its obligations under the Plan.

*Other Compensation and Benefit Plans*. The adoption of the Plan shall not affect any other share incentive or other compensation plans in effect for the Company or any Subsidiary, nor shall the Plan preclude the Company from establishing any other forms of share incentive or other compensation or benefit program for employees of the Company or any Subsidiary. The amount of any compensation deemed to be received by a Participant pursuant to an Award shall not constitute includable compensation for purposes of determining the amount of benefits to which a Participant is entitled under any other compensation or benefit plan or program of the Company or a Subsidiary, including, without limitation, under any pension or severance benefits plan, except to the extent specifically provided by the terms of any such plan.

*Plan Binding on Transferees*. The Plan shall be binding upon the Company, its transferees and assigns, and the Participant, the Participant's executor, administrator and permitted transferees and beneficiaries.

*Severability*. If any provision of the Plan or any Award Agreement shall be determined to be illegal or unenforceable by any court of law in any jurisdiction, the remaining provisions hereof and thereof shall be severable and enforceable in accordance with their terms, and all provisions shall remain enforceable in any other jurisdiction.

*Governing Law*. The Plan, all Awards and all Award Agreements, and all claims or causes of action (whether in contract, tort or statute) that may be based upon, arise out of or relate to the Plan, any Award or Award Agreement, or the negotiation, execution or performance of any such documents or matter related thereto (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with the Plan, any Award or Award Agreement, or as an inducement to enter into any Award Agreement), shall be governed by, and enforced in accordance with, the internal laws of the State of Delaware, including its statutes of limitations and repose, but without regard to any borrowing statute that would result in the application of the statute of limitations or repose of any other jurisdiction.

*No Fractional Shares*. No fractional shares of Common Stock shall be issued or delivered pursuant to the Plan or any Award, and the Committee shall determine whether cash, other securities or other property shall be paid or transferred in lieu of any fractional shares of Common Stock or whether such fractional shares or any rights thereto shall be canceled, terminated or otherwise eliminated.

*No Guarantees Regarding Tax Treatment*. Neither the Company nor the Committee make any guarantees to any Person regarding the tax treatment of Awards or payments made under the Plan. Neither the Company nor the Committee has any obligation to take any action to prevent the assessment of any tax on any Person with respect to any Award under Section 409A of the Code, Section 4999 of the Code or otherwise and neither the Company nor the Committee shall have any liability to a Person with respect thereto.

*Data Protection*. By participating in the Plan, each Participant consents to the collection, processing, transmission and storage by the Company, its Subsidiaries and any third party administrators of any data of a professional or personal nature for the purposes of administering the Plan and in connection with a Participant's status as a stockholder of the Company upon the issuance of any shares of Common Stock pursuant to an Award.

*Awards to Non-U.S. Participants*. To comply with the laws in countries other than the United States in which the Company or any of its Subsidiaries or Affiliates operates or has employees, Non-Employee Directors or consultants, the Committee, in its sole discretion, shall have the power and authority to (i) modify the terms and conditions of any Award granted to Participants outside the United States to comply with applicable foreign laws, (ii) take any action, before or after an Award is made, that it deems advisable to obtain approval or comply with any necessary local government regulatory exemptions or approvals and (iii) establish subplans and modify exercise procedures and other terms and procedures, to the extent such actions may be necessary or advisable. Any subplans and modifications to Plan terms and procedures established under this Section 14.20 by the Committee shall be attached to this Plan document as appendices.

<u>Term; Amendment and Termination; Stockholder Approval</u>.

*Term*. The Board has adopted this plan and the Plan shall be effective as of the day immediately prior to the date on which the Company's registration statement on Form S-1 in connection with its initial public offering of Common Stock is declared effective by the Securities and Exchange Commission under the Securities Act, subject to approval of the Plan by the stockholders

------

of the Company within 12 months of the adoption (the "Effective Date"). Subject to Section 15.2 hereof, the Plan shall terminate on the tenth anniversary of the Effective Date.

*Amendment and Termination*. The Board may from time to time and in any respect, amend, modify, suspend or terminate the Plan; <u>provided</u>, <u>however</u>, that no amendment, modification, suspension or termination of the Plan shall materially and adversely affect any Award theretofore granted without the consent of the Participant or the permitted transferee of the Award. The Board may seek the approval of any amendment, modification, suspension or termination by the Company's stockholders to the extent it deems necessary in its discretion for purposes of compliance with Section 422 of the Code or for any other purpose, and shall seek such approval to the extent it deems necessary in its discretion to comply with applicable law or listing requirements of NASDAQ or other exchange or securities market. Notwithstanding the foregoing, the Board shall have broad authority to amend the Plan or any Award under the Plan without the consent of a Participant to the extent it deems necessary or desirable in its discretion to comply with, take into account changes in, or interpretations of, applicable tax laws, securities laws, employment laws, accounting rules and other applicable laws, rules and regulations.
