**KYMERA THERAPEUTICS, INC.** 

**500 North Beacon Street, Fourth Floor, Watertown, MA 02472** 

**NOTICE OF 2026 ANNUAL MEETING OF SHAREHOLDERS** 

**To be held June 24, 2026** 

Notice is hereby given that the 2026 Annual Meeting of Shareholders, or Annual Meeting, of Kymera Therapeutics, Inc., will be held online on June 24, 2026 at 8:30 a.m. Eastern Time. The Annual Meeting will be a virtual meeting, which will be conducted via live webcast. You will be able to attend the meeting online and vote electronically at <u>www.virtualshareholdermeeting.com/KYMR2026</u>.

The purpose of the Annual Meeting is the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.To elect four class III directors to our board of directors, each to serve until the 2029 annual meeting of shareholders and until his or her successor has been duly elected and qualified, or until his or her earlier death, resignation or removal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.To approve, on a non-binding advisory basis, the compensation of our named executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.To ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.To transact any other business properly brought before the Annual Meeting or any adjournment or postponement of the Annual Meeting.

Shareholders of record at the close of business on April 27, 2026, the record date for the Annual Meeting, are entitled to notice of, and to vote at, the Annual Meeting or any adjournment or postponement of the Annual Meeting.

You can find more information on each of the matters to be voted on at the Annual Meeting, including information regarding the nominees for election to our board of directors, in the accompanying proxy statement. The board of directors recommends a vote "FOR" the election of the four nominees for class III directors; "FOR" the advisory resolution to approve the compensation of our named executive officers, as disclosed in the accompanying proxy statement; and "FOR" the ratification of the appointment of our independent registered public accounting firm for the fiscal year ending December 31, 2026, as disclosed in the accompanying proxy statement.

We are pleased to comply with the rules of the Securities and Exchange Commission that allow companies to distribute their proxy materials over the Internet under the "notice and access" approach. As a result, we are mailing to our shareholders a Notice of Internet Availability of Proxy Materials, or Notice of Availability, instead of a paper copy of our proxy materials and our Annual Report for the fiscal year ended December 31, 2025, or the 2025 Annual Report. We will mail the Notice of Availability on or about April 29, 2026, and it contains instructions on how to access those documents and to cast your vote over the Internet. This process allows us to provide our shareholders with the information they need on a more timely basis, while reducing the environmental impact and lowering the costs of printing and distributing our proxy materials. If you would like to receive a printed copy of our proxy materials, including our proxy statement, our 2025 Annual Report and a form of proxy card, free of charge, please follow the instructions on the Notice of Availability.

------

In order to attend the Annual Meeting virtually, you will be required to enter the control number provided in the Notice of Availability or the proxy card at <u>www.virtualshareholdermeeting.com/KYMR2026</u>. Beneficial owners of shares held in street name will need to follow the instructions provided in the voting instructions form by the broker, bank or other nominee that holds their shares. Please see the "General Information" section of the proxy statement that accompanies this notice for more details regarding the logistics of the virtual Annual Meeting. You will not be able to attend the Annual Meeting in person.

Your vote is important. Whether or not you are able to attend the Annual Meeting and vote your shares online, it is important that your shares be represented. To ensure that your vote is recorded promptly, please vote as soon as possible, even if you plan to attend the Annual Meeting, by submitting your proxy over the Internet or by telephone as described in the instructions included in the Notice of Availability or by signing, dating and returning the proxy card. Voting promptly will help avoid the additional expense of further solicitation to ensure a quorum at the meeting.

**KYMERA THERAPEUTICS, INC** 

**PROXY STATEMENT** 

**FOR THE 2026 ANNUAL MEETING OF SHAREHOLDERS** 

**GENERAL IN** **FORMATION** 

**When is this proxy statement and the accompanying materials scheduled to be sent to shareholders?** 

We have elected to provide access to our proxy materials to our shareholders via the Internet. Accordingly, on or about April 29, 2026, we will begin mailing the Notice of Availability. Our proxy materials, including the Notice of the 2026 Annual Meeting of Shareholders, this proxy statement and the accompanying proxy card or, for shares held in street name (i.e., held for your account by a broker, bank or other nominee), a voting instruction form, and the 2025 Annual Report to Shareholders, or the 2025 Annual Report, will be mailed or made available to shareholders on the Internet on or about the same date.

**Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials?** 

Pursuant to rules adopted by the SEC, for most shareholders, we are providing access to our proxy materials over the Internet rather than printing and mailing our proxy materials. We believe following this process will expedite the receipt of such materials and will help lower our costs and reduce the environmental impact of our proxy materials. Therefore, the Notice of Availability was mailed to holders of record and beneficial owners of our common stock starting on or about April 29, 2026. The Notice of Availability provides instructions as to how shareholders may access and review our proxy materials, including the Notice of the 2026 Annual Meeting of Shareholders, this proxy statement, the proxy card and our 2025 Annual Report, on the website referred to in the Notice of Availability or, alternatively, how to request that a printed copy of the proxy materials, including a proxy card, be sent to them by mail. The Notice of Availability also provides voting instructions. In addition, shareholders of record may request to receive the proxy materials in printed form by mail or electronically by e-mail on an ongoing basis for future shareholder meetings. Please note that, while our proxy materials are available at the website referenced in the Notice of Availability and our Notice of the 2026 Annual Meeting of Shareholders, this proxy statement and our 2025 Annual Report are available on our website, no other information contained on either website is incorporated by reference in, or considered to be a part of, this proxy statement.

**Who is soliciting my vote?** 

Our board of directors is soliciting your vote for the Annual Meeting.

**Who pays the cost for soliciting proxies?** 

We are making this solicitation and will pay the entire cost of preparing and distributing the Notice of Availability and our proxy materials and soliciting votes. If you choose to access the proxy materials or vote over the Internet, you are responsible for any Internet access charges that you may incur. Our officers and employees may, without compensation other than their regular compensation, solicit proxies through further mailings, personal conversations, facsimile transmissions, e-mails, or otherwise.

**When is the record date for the Annual Meeting?** 

The record date for determination of shareholders entitled to vote at the Annual Meeting is the close of business on April 27, 2026.

**How many votes can be cast by all shareholders?** 

There were 82,257,588 shares of our common stock, par value $0.0001 per share, outstanding on April 27, 2026, all of which are entitled to vote with respect to all matters to be acted upon at the Annual Meeting of Shareholders on June 24, 2026, or the Annual Meeting. Each shareholder of record is entitled to one vote for each share of our common stock held by such shareholder. None of our shares of undesignated preferred stock were outstanding as of April 27, 2026.

------

**How do I vote?** 

If you are a shareholder of record, there are several ways for you to vote your shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*By Internet prior to the Annual Meeting*. You may vote at <u>www.proxyvote.com</u>, 24 hours a day, seven days a week, by following the instructions at that site for submitting your proxy electronically. You will be required to enter the control number provided in the Notice of Availability or the proxy card. Votes submitted through the Internet must be received no later than 11:59 p.m. Eastern Time on June 23, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*By QR Code.* You may vote using your mobile device to scan the QR code on your proxy card. Votes submitted by scanning your QR code must be received no later than 11:59 p.m. Eastern Time on June 23, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*By Telephone*. You may vote using a touch-tone telephone by calling 1-800-690-6903, 24 hours a day, seven days a week. You will be required to provide the control number provided in the Notice of Availability or the proxy card. Votes submitted by telephone must be received no later than 11:59 p.m. Eastern Time on June 23, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*By Mail*. If you requested and received a printed copy of the proxy materials, you may vote by mail by completing, signing and dating the enclosed proxy card and returning it in the enclosed prepaid envelope. Votes submitted through the mail must be received no later than June 23, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*During the Annual Meeting*. You may vote your shares during the live webcast of the Annual Meeting by visiting <u>www.virtualshareholdermeeting.com/KYMR2026</u>. You will be required to enter the control number provided in the Notice of Availability or the proxy card. If you vote by proxy prior to the Annual Meeting and choose to attend the Annual Meeting online, there is no need to vote again during the Annual Meeting unless you wish to change your vote.

If the Annual Meeting is adjourned or postponed, the deadlines above may be extended.

If you are a beneficial owner of shares held in street name by your broker, bank or other nominee, you should have received a voting instruction form with these proxy materials from your broker, bank or other nominee rather than from us. The voting deadlines and availability of telephone and Internet voting for beneficial owners of shares will depend on the voting processes of the broker, bank or other nominee that holds your shares. Therefore, we urge you to carefully review and follow the voting instruction form and any other materials that you receive from that organization. **If you hold your shares of Kymera Therapeutics common stock in multiple accounts, you should vote your shares as described in each set of proxy materials you receive.**

If you submit a proxy without giving voting instructions, your shares will be voted in the manner recommended by the board of directors on all matters presented in this proxy statement, and as the persons named as proxies in the proxy card may determine in their discretion with respect to any other matters properly presented at the Annual Meeting. You may also authorize another person or persons to act for you as proxy in a writing, signed by you or your authorized representative, specifying the details of those proxies' authority. The original writing must be given to each of the named proxies, although it may be sent to them by electronic transmission if, from that transmission, it can be determined that the transmission was authorized by you.

If any other matters are properly presented for consideration at the Annual Meeting, including, among other things, consideration of a motion to adjourn the Annual Meeting to another time or place (including, without limitation, for the purpose of soliciting additional proxies), the persons named in your proxy and acting thereunder will have discretion to vote on those matters in accordance with their best judgment. We do not currently anticipate that any other matters will be raised at the Annual Meeting.

**How can I virtually attend the Annual Meeting?** 

To attend and participate in the Annual Meeting, shareholders will need to access the live webcast of the meeting. To do so, shareholders of record will need to visit <u>www.virtualshareholdermeeting.com/KYMR2026</u> and enter the control number provided in the Notice of Availability. Beneficial owners of shares held in street name will need to follow the instructions provided in the voting instructions form by the broker, bank or other nominee that holds their shares.

------

The live webcast of the Annual Meeting will begin promptly at 8:30 a.m. Eastern Time on June 24, 2026. We encourage shareholders to login to this website and access the webcast before the Annual Meeting's start time. Online check-in will begin at 8:15 a.m. Eastern Time, and you should allow ample time before the meeting for check-in procedures.

We will have technicians ready to assist you with any technical difficulties you may have accessing the Annual Meeting, voting at the Annual Meeting or submitting questions at the Annual Meeting. If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the virtual meeting login page.

If you wish to submit a question during the Annual Meeting, you may log into, and submit a question on, the virtual meeting platform at <u>www.virtualshareholdermeeting.com/KYMR2026</u> and following the instructions there. Only shareholders will be able to submit a question. Shareholders will be able to submit questions upon logging into the virtual platform 15 minutes prior to the start of the Annual Meeting. The question portal will close after the preliminary results of the voting are reported. In order to provide an opportunity to as many shareholders as possible who wish to ask a question, each shareholder will be limited to one question. We will endeavor to answer as many questions submitted by shareholders as time permits. We reserve the right to edit profanity or other inappropriate language and to exclude questions regarding topics that are not pertinent to meeting matters or company business. If we receive substantially similar questions, we may group such questions together and provide a single response to avoid repetition. Questions regarding topics that are not pertinent to meeting matters or company business will not be answered.

**How do I revoke my proxy?** 

If you are a shareholder of record, you may revoke your proxy by (1) following the instructions on the Notice of Availability and submitting a new vote by Internet, telephone or mail using the procedures described in the "How do I Vote?" section above before the applicable deadline, (2) attending and voting at the Annual Meeting (although attendance at the Annual Meeting will not in and of itself revoke a proxy), or (3) by filing an instrument in writing revoking the proxy or another duly executed proxy bearing a later date with our corporate secretary. Any written notice of revocation or subsequent proxy card must be received by our corporate secretary prior to the taking of the vote at the Annual Meeting. Such written notice of revocation or subsequent proxy card should be hand delivered to our corporate secretary or sent to our principal executive offices at Kymera Therapeutics, Inc., 500 North Beacon Street, Fourth Floor, Watertown, Massachusetts 02472, Attention: Corporate Secretary.

If a broker, bank, or other nominee holds your shares, you must contact such broker, bank, or nominee in order to find out how to change your vote.

**How is a quorum reached?** 

Our Second Amended and Restated Bylaws, or bylaws, provide that a majority of the shares entitled to vote, present in person or represented by proxy, will constitute a quorum for the transaction of business at the Annual Meeting. There are 82,257,588 shares of our common stock outstanding and entitled to vote on the record date. Therefore, a quorum will be present if 41,128,795 shares of our common stock are present in person or represented by executed proxies timely received by us at the Annual Meeting. Shares present virtually during the Annual Meeting will be considered shares of common stock represented in person at the meeting.

Under the General Corporation Law of the State of Delaware, shares that are voted "abstain" or "withheld" and broker "non-votes" are counted as present for purposes of determining whether a quorum is present at the Annual Meeting. If a quorum is not present, the meeting may be adjourned until a quorum is obtained.

**How is the vote counted?** 

Under our bylaws, any proposal other than an election of directors is decided by a majority of the votes properly cast for and against such proposal, except where a larger vote is required by law or by our Fourth Amended and Restated Certificate of Incorporation, or certificate of incorporation, or bylaws.

------

Each holder of common stock is entitled to one vote for each share held by such shareholder as of the record date on each matter to come before the Annual Meeting, including the election of a director. Votes cast during the Annual Meeting or by proxy by mail, via the Internet or by telephone will be tabulated by the inspector of election appointed for the Annual Meeting, who will also determine whether a quorum is present. Abstentions and broker "non-votes" are not included in the tabulation of the voting results on any such proposal and, therefore, do not have an impact on such proposals. A broker "non-vote" occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner.

If your shares are held in street name by a broker, bank or other nominee, your broker, bank or other nominee is required to vote your shares according to your instructions. If you do not give instructions to your broker, bank or other nominee, the broker, bank or other nominee will still be able to vote your shares with respect to certain "discretionary" items, but will not be allowed to vote your shares with respect to "non-discretionary" items. Each of Proposal No. 1 and Proposal No. 2 is a "non-discretionary" item. If you do not instruct your broker how to vote with respect to these proposals, your broker, bank or other nominee may not vote for this proposal, and those votes will be counted as broker "non-votes." Proposal No. 3 is considered to be a discretionary item, and your broker, bank or other nominee will be able to vote on this proposal even if it does not receive instructions from you.

To be elected, the directors nominated via Proposal No. 1 must receive a plurality of the votes properly cast on the proposal, meaning that the four director nominees receiving the most votes "FOR" will be elected. If nominees are unopposed, election requires only a single "FOR" vote. Shares voting "withheld" have no effect on the election of directors.

**What votes are required for each proposal?** 

The vote required, and the method of calculation, for each proposal at the Annual Meeting is described below.

---

| | | |
|:---|:---|:---|
| **Proposal** | **Vote**<br>**Required** | **Discretionary**<br>**Voting**<br>**Permitted?** |
| Election of Directors | Plurality | No |
| Approval, on a Non-Binding, Advisory Basis, of the Compensation of our<br> Named Executive Officers | Majority of<br>votes cast | No |
| Approval of the Ratification of the Appointment of Ernst & Young LLP as<br> our Independent Registered Public Accounting Firm | Majority of<br>votes cast | Yes |

---

***Proposal One - Election of Directors*** 

The four class III director nominees receiving the highest number of votes, in person or by proxy, will be elected. You may vote "FOR" all nominees, "WITHHOLD" for all nominees, or you may vote "FOR" all nominees except for any nominee you "WITHHOLD" by specifying the name of the nominee on your proxy card. This proposal is not considered to be a discretionary item, so if you do not instruct your broker how to vote with respect to this proposal, your broker may not vote on this proposal, and those votes will be counted as broker "non**-**votes." Withheld votes and broker non**-**votes will have no effect on the outcome of the election of the directors.

------

***Proposal Two - Approval, on a Non-Binding, Advisory Basis, of the Compensation of our Named Executive Officers*** 

Approval of this proposal requires the affirmative vote of a majority of the votes properly cast for and against this proposal. You may vote "FOR," "AGAINST," or "ABSTAIN" from voting on this proposal. If you abstain from voting on this proposal, your shares will not be counted as "votes cast" with respect to this proposal, and the abstention will have no effect on this proposal. This proposal is not considered to be a discretionary item, so if you do not instruct your broker how to vote with respect to this proposal, your broker may not vote on this proposal, and those votes will be counted as broker "non**-**votes." Broker non**-**votes will have no effect on the outcome of this proposal.

***Proposal Three - Approval of the Ratification of Ernst & Young LLP as our Independent Registered Public Accounting Firm*** 

Approval of this proposal requires the affirmative vote of a majority of the votes properly cast for and against this proposal. You may vote "FOR," "AGAINST," or "ABSTAIN" from voting on this proposal. If you abstain from voting on this proposal, your shares will not be counted as "votes cast" with respect to this proposal, and the abstention will have no effect on the proposal. This proposal is considered to be a discretionary item, and your broker will be able to vote on this proposal even if it does not receive instructions from you. Accordingly, we do not anticipate that there will be any broker non**-**votes on this proposal; however, any broker non**-**votes will not be counted as "votes cast" and will therefore have no effect on this proposal.

**How may shareholders submit matters for consideration at an annual meeting?** 

The required notice must be in writing and received by our corporate secretary at our principal executive offices not later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the first anniversary of the preceding year's annual meeting. However, in the event that the date of the annual meeting is convened more than 30 days before or more than 60 days after the first anniversary of the preceding year's annual meeting, or if no annual meeting were held in the preceding year, a shareholder's notice must be so received not later than the close of business on the later of (A) the ninetieth (90<sup>th</sup>) day prior to the scheduled date of such annual meeting or (B) the tenth (10<sup>th</sup>) day following the day on which public announcement of the date of such annual meeting was first made.

In addition, any shareholder proposal intended to be included in the proxy statement for the next annual meeting of our shareholders in 2027 must also satisfy the requirements of SEC Rule 14a-8 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and be received not later than December 30, 2026. If the date of the annual meeting is moved by more than 30 days from the date contemplated at the time of the previous year's proxy statement, then notice must be received within a reasonable time before we begin to print and send proxy materials. If that happens, we will publicly announce the deadline for submitting a proposal in a press release or in a document filed with the SEC.

In addition to satisfying the foregoing requirements, to comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees other than the company's nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than April 26, 2027. Shareholder proposals and the required notice should be addressed to our Secretary at our principal executive offices at the address set forth above.

**How can I know the voting results?**

**PROPOSAL NO. 1 - ELECTION OF CLASS III DIRECTORS**

Our board of directors currently consists of nine members. In accordance with the terms of our certificate of incorporation and bylaws, our board of directors is divided into three classes, class I, class II and class III, with members of each class serving staggered three-year terms. The members of the classes are divided as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the class I directors are Pamela Esposito, Ph.D., Gorjan Hrustanovic, Ph.D. and Victor Sandor, M.D.C.M., and their terms will expire at the annual meeting of shareholders to be held in 2027;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the class II directors are Jeffrey Albers, J.D., MBA and Felix J. Baker, Ph.D., and their terms will expire at the annual meeting of shareholders to be held in 2028; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the class III directors are Bruce Booth, D.Phil., Nello Mainolfi, Ph.D., John Maraganore, Ph.D. and Elena Ridloff, CFA, and their terms will expire at the Annual Meeting.

Upon the expiration of the term of a class of directors, directors in that class will be eligible to be elected for a new three-year term at the annual meeting of shareholders in the year in which their term expires.

Our certificate of incorporation and bylaws provide that the authorized number of directors may be changed only by resolution of our board of directors. Our certificate of incorporation also provides that our directors may be removed only for cause by the affirmative vote of the holders of at least two-thirds (2/3) of the outstanding shares then entitled to vote at an annual election of directors, and that any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office.

Our board of directors has nominated Bruce Booth, D.Phil., Nello Mainolfi, Ph.D., John Maraganore, Ph.D. and Elena Ridloff, CFA, for election as the class III directors at the Annual Meeting. All of the nominees are currently directors, and each has indicated a willingness to continue to serve as a director, if elected.

Our Nominating and Corporate Governance Committee Policies and Procedures for Director Candidates, or the Director Guidelines, provide that factors such as a candidate's character, judgment, diversity, independence, skills, education, expertise and absence of conflicts of interest should be considered in determining director candidates. Our priority in selection of board members is identification of members who will further the interests of our shareholders through their established records of professional accomplishment, their ability to contribute positively to the collaborative culture among board members, and their knowledge of our business and understanding of the competitive landscape in which we operate and adherence to high ethical standards.

**Vote Required and Board of Directors' Recommendation** 

The four nominees for class III director who receive the most "FOR" votes (also known as a plurality) will be elected. Shares that are voted "withheld" and broker non-votes will have no effect on the election of directors.

However, if the nominees are unable to serve or for good cause will not serve as directors, the proxies will be voted for the election of such substitute nominee as our board of directors may designate.

The proposal for the election of directors relates solely to the election of class III directors nominated by our board of directors.

**PROPOSAL NO. 2 - NON-BINDING, ADVISORY VOTE ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS** 

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, and Section 14A of the Exchange Act, our shareholders are entitled to vote to approve, on a non-binding advisory basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with SEC rules. This is commonly known as a "Say-on-Pay" proposal. At our 2022 Annual Meeting of Shareholders, our shareholders approved one year as the preferred frequency for holding non-binding advisory votes to approve the compensation of our named executive officers. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this proxy statement. The compensation of our named executive officers subject to the vote is disclosed in the Compensation Discussion and Analysis, the compensation tables, and the related narrative disclosure contained in this proxy statement. As discussed in those disclosures, we believe that our compensation policies and decisions are strongly aligned with our shareholders' interests and are consistent with current market practices. Compensation of our named executive officers is designed to enable us to attract and retain talented and experienced executives to lead us successfully in a competitive environment. Accordingly, we are asking our shareholders to vote for the following resolution:

RESOLVED, that the company's shareholders approve, on a non-binding, advisory basis, the compensation of the company's named executive officers, as disclosed in the proxy statement for the 2026 Annual Meeting of Shareholders, including the Compensation Discussion and Analysis, compensation tables and narrative discussion.

This vote is advisory, and therefore not binding on us, the board of directors, or our Compensation and Talent Committee, or "Compensation Committee." However, our board of directors and Compensation Committee value your opinion and intend to consider the outcome of the vote when making compensation decisions in the future.

**Vote Required and Board of Directors' Recommendation** 

A majority of the votes properly cast FOR this proposal is required to approve, on an advisory basis, the compensation of our named executive officers. Shares that are voted "abstain" and broker non-votes will have no effect on the outcome of this proposal.

**The board of directors recommends voting "FOR" Proposal No. 2 to approve, on a non-binding, advisory basis, the compensation of our named executive officers.**

**PROPOSAL NO. 3 - RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS KYMERA THERAPEUTICS' INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2026** 

Kymera Therapeutics' shareholders are being asked to ratify the appointment by the Audit Committee of the board of directors of Ernst & Young LLP as Kymera Therapeutics' independent registered public accounting firm for the fiscal year ending December 31, 2026.

The Audit Committee is solely responsible for selecting Kymera Therapeutics' independent registered public accounting firm for the fiscal year ending December 31, 2026. Shareholder approval is not required to appoint Ernst & Young LLP as Kymera Therapeutics' independent registered public accounting firm.

If the shareholders do not ratify this appointment, the Audit Committee will reconsider whether to retain Ernst & Young LLP. If the selection of Ernst & Young LLP is ratified, the Audit Committee, at its discretion, may direct the appointment of a different independent registered public accounting firm at any time it decides that such a change would be in the best interest of Kymera Therapeutics and its shareholders.

A representative of Ernst & Young LLP is expected to be present at the Annual Meeting and will have an opportunity to make a statement if he or she desires to do so and to respond to appropriate questions from our shareholders.

Our Nominating and Corporate Governance Committee is responsible for identifying individuals qualified to serve as directors, consistent with criteria approved by our board of directors, and recommending such persons to be nominated for election as directors, except where we are legally required by contract, law or otherwise to provide third parties with the right to nominate.

The process followed by our Nominating and Corporate Governance Committee to identify and evaluate director candidates includes requests to board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates, and interviews of selected candidates by management, recruiters, members of the committee and our board. The qualifications, qualities and skills that our Nominating and Corporate Governance Committee believes must be met by a committee recommended nominee for a position on our board of directors are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Nominees should demonstrate high standards of personal and professional ethics and integrity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Nominees should have proven achievement and competence in the nominee's field and the ability to exercise sound business judgment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Nominees should have skills that are complementary to those of the existing board.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Nominees should have the ability to assist and support management and make significant contributions to the company's success.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Nominees should have an understanding of the fiduciary responsibilities that is required of a member of the board of directors and the commitment of time and energy necessary to diligently carry out those responsibilities.

Shareholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration as potential director candidates. Any such proposals should be submitted to our corporate secretary at our principal executive offices no later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the one-year anniversary of the date of the preceding year's annual meeting and should include appropriate biographical and background material to allow the Nominating and Corporate Governance Committee to properly evaluate the potential director candidate and the number of shares of our stock beneficially owned by the shareholder proposing the candidate. Shareholder proposals should be addressed to Kymera Therapeutics, Inc., 500 North Beacon Street, Fourth Floor, Watertown, Massachusetts 02472, Attention: Corporate Secretary. Assuming that biographical and background material have been provided on a timely basis in accordance with our bylaws, any recommendations received from shareholders will be evaluated in the same manner as potential nominees proposed by the Nominating and Corporate Governance Committee. If our board of directors determines to nominate a shareholder recommended candidate and recommends his or her election, then his or her name will be included on our proxy card for the next annual meeting of shareholders. See "Shareholder Proposals" for a discussion of submitting shareholder proposals.

**Director Independence** 

Applicable Nasdaq Global Market, or Nasdaq, rules require a majority of a listed company's board of directors to be comprised of independent directors within one year of listing. In addition, the Nasdaq rules require that, subject to specified exceptions, each member of a listed company's Audit, Compensation and Nominating and Corporate Governance Committees be independent and that Audit Committee members also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act and that Compensation Committee members satisfy independence criteria set forth in Rule 10C-1 under the Exchange Act. Under applicable Nasdaq rules, a director will only qualify as an "independent director" if, in the opinion of the listed company's board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3 under the Exchange Act, a member of an Audit Committee of a listed company may not, other than in his or her capacity as a member of the Audit Committee, the board of directors, or any other board committee: (i) accept, directly or indirectly, any consulting, advisory, or other

------

compensatory fee from the listed company or any of its subsidiaries, other than compensation for board service; or (ii) be an affiliated person of the listed company or any of its subsidiaries. In addition, in affirmatively determining the independence of any director who will serve on a company's Compensation Committee, Rule 10C-1 under the Exchange Act requires that a company's board of directors must consider all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director's ability to be independent from management in connection with the duties of a Compensation Committee member, including, but not limited to: the source of compensation of the director, including any consulting, advisory or other compensatory fee paid by such company to the director, and whether the director is affiliated with the company or any of its subsidiaries or affiliates.

Our board of directors has determined that all members of the board of directors, except Nello Mainolfi, Ph.D., are independent directors, including for purposes of the rules of Nasdaq and the SEC. In making such independence determination, our board of directors considered the relationships that each director has with us and all other facts and circumstances that our board of directors deemed relevant in determining their independence, including the potential deemed beneficial ownership of our capital stock by each director, including non-employee directors that are affiliated with certain of our major shareholders. In considering the independence of the directors listed above, our board of directors considered the association of our directors with the holders of more than 5% of our common stock. There are no family relationships among any of our directors or executive officers. Dr. Mainolfi is not an independent director under these rules because he is currently employed as the Chief Executive Officer of the company.

**Board Committees** 

Our board of directors has established an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. Each of the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee operates under a charter that satisfies the applicable standards of the SEC and Nasdaq. Each such committee reviews its respective charter at least annually. A current copy of the charter for each of the Audit Committee, Compensation Committee, Nominating and Corporate Governance Committee is posted on the corporate governance section of our website, <u>https://investors.kymeratx.com/corporate-governance/documents-charters</u>.

The table below shows current membership for each of the standing committees of our board of directors.

**Compensation Committee** 

Jeffrey Albers, J.D., MBA, Felix J. Baker, Ph.D., and John Maraganore, Ph.D. serve on the Compensation Committee, which is chaired by Jeffrey Albers, J.D., MBA. Our board of directors has determined that each member of the Compensation Committee is "independent" as defined in the applicable Nasdaq rules. During the fiscal year ended December 31, 2025, the Compensation Committee met five times and acted via written consent twice. The Compensation Committee's responsibilities include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•annually reviewing and recommending to the board of directors the corporate goals and objectives relevant to the compensation of our Chief Executive Officer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•evaluating the performance of our Chief Executive Officer in light of such corporate goals and objectives and, based on such evaluation, (i) recommending to the board of directors the cash compensation of our Chief Executive Officer and (ii) reviewing and recommending to the board of directors any grants and awards to our Chief Executive Officer under equity-based plans;

**Nominating and Corporate Governance Committee** 

Pamela Esposito, Ph.D. and Gorjan Hrustanovic, Ph.D. serve on the Nominating and Corporate Governance Committee, which is chaired by Pamela Esposito. Our board of directors has determined that each member of the Nominating and Corporate Governance Committee is "independent" as defined in the applicable Nasdaq rules. During the fiscal year ended December 31, 2025, the Nominating and Corporate Governance Committee met two times and acted via written consent once. The Nominating and Corporate Governance Committee's responsibilities include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•developing and recommending to the board of directors criteria for board and committee membership;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•establishing procedures for identifying and evaluating board of director candidates, including nominees recommended by shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•reviewing the composition of the board of directors to ensure that it is composed of members containing the appropriate skills and expertise to advise us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•identifying individuals qualified to become members of the board of directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•recommending to the board of directors the persons to be nominated for election as directors and to each of the board's committees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•developing and recommending to the board of directors a code of business conduct and ethics and a set of corporate governance guidelines; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•overseeing the evaluation of our board of directors.

In 2023, the Nominating and Corporate Governance Committee led a self-assessment of our board of directors and board committees with interviews conducted by the Corporate Secretary. The feedback was discussed by the Nominating and Corporate Governance Committee and the entire board of directors. Such assessments are done periodically and help to inform our practices and to identify potential improvements to our practices and policies.

The Nominating and Corporate Governance Committee considers candidates for board of director membership suggested by its members and our Chief Executive Officer. Additionally, in selecting nominees for directors, the Nominating and Corporate Governance Committee will review candidates recommended by shareholders in the same manner and using the same general criteria as candidates recruited by the committee and/or recommended by our board of directors. Any shareholder who wishes to recommend a candidate for consideration by the committee as a nominee for director should follow the procedures described later in this proxy statement under the heading "Shareholder Proposals." The Nominating and Corporate Governance Committee will also consider whether to nominate any person proposed by a shareholder in accordance with the provisions of our bylaws relating to shareholder nominations as described later in this proxy statement under the heading "Shareholder Proposals."

**Identifying and Evaluating Director Nominees** 

Our board of directors is responsible for filling vacancies on our board of directors and for nominating candidates for election by our shareholders each year in the class of directors whose term expires at the relevant annual meeting. The board of directors delegates the selection and nomination process to the Nominating and Corporate Governance Committee, with the expectation that other members of the board of directors, and of management, will be requested to take part in the process as appropriate.

Generally, the Nominating and Corporate Governance Committee identifies candidates for director nominees in consultation with management, through the use of search firms or other advisors, through the recommendations submitted by shareholders or through such other methods as the Nominating and Corporate Governance Committee deems to be helpful to identify candidates. Once candidates have been identified, the Nominating and Corporate

------

Governance Committee confirms that the candidates meet all of the minimum qualifications for director nominees established by the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee may gather information about the candidates through interviews, detailed questionnaires, comprehensive background checks or any other means that the Nominating and Corporate Governance Committee deems to be appropriate in the evaluation process. The Nominating and Corporate Governance Committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of our board of directors. Based on the results of the evaluation process, the Nominating and Corporate Governance Committee recommends candidates for the board of directors' approval to fill a vacancy or as director nominees for election to the board of directors by our shareholders each year in the class of directors whose term expires at the relevant annual meeting.

**Board and Committee Meetings Attendance** 

The full board of directors met five times and acted via written consent four times during 2025. During 2025, each member of the board of directors attended in person or participated in 75% or more of the aggregate of (i) the total number of meetings of the board of directors (held during the period for which such person has been a director), and (ii) the total number of meetings held by all committees of the board of directors on which such person served (during the periods that such person served).

**Director Attendance at Annual Meeting of Shareholders** 

Directors are responsible for attending the annual meeting of shareholders to the extent practicable. Present at our annual meeting of shareholders in 2025 were seven out of our nine directors.

**Policy on Trading, Pledging and Hedging of Company Stock** 

It is our policy to comply with applicable insider trading laws, rules and regulations, and any exchange listing standards when engaging in transactions in company securities. Certain transactions in our securities (such as purchases and sales of publicly traded put and call options, and short sales) create a heightened compliance risk or could create the appearance of misalignment between management and shareholders. In addition, securities held in a margin account or pledged as collateral may be sold without consent if the owner fails to meet a margin call or defaults on the loan, thus creating the risk that a sale may occur at a time when an officer or director is aware of material, nonpublic information or otherwise is not permitted to trade in Kymera Therapeutics securities.

Our insider trading policy expressly prohibits derivative transactions of our stock by our executive officers, directors and employees. Our insider trading policy expressly prohibits purchases of any derivative securities that provide the economic equivalent of ownership.

**Compensation Recovery Policy** 

Our board of directors adopted a compensation recovery policy effective as of November 1, 2023, in compliance with the Nasdaq listing rules, which requires recovery from executive officers of incentive-based compensation that is earned, granted or vested based on the achievement of a financial reporting measure in the event of a required accounting restatement of previously issued financial statements. The recoverable compensation includes any compensation received after the effective date of the compensation recovery policy and in the three-year fiscal period preceding the date we were required to prepare the accounting restatement that is in excess of the amount that would have been earned, paid or vested had it been calculated based on the restated financial statements. Recovery is required regardless of fault or a covered officer's role in the financial reporting process. The compensation recovery policy has been filed as Exhibit 97 to our Annual Report on Form 10-K for the year ended December 31, 2025. At no time during or after the year ended December 31, 2025, were we required to prepare an accounting restatement that required recovery of erroneously awarded compensation pursuant to the compensation recovery policy, nor was there, on December 31, 2025, an outstanding balance of erroneously awarded compensation to be recovered from the application of the policy to a prior restatement.

------

**Code of Business Conduct and Ethics** 

We have adopted a written Code of Business Conduct and Ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A current copy of the code is posted on the corporate governance section of our website, which is located at <u>https://investors.kymeratx.com/corporate-governance/documents-charters</u>. If we make any substantive amendments to, or grant any waivers from, the code of business conduct and ethics for any officer or director, we will disclose the nature of such amendment or waiver on our website or in a current report on Form 8-K.

**Board Leadership Structure and Board's Role in Risk Oversight** 

Currently, the role of chairperson of the board is separated from the role of Chief Executive Officer, and we plan to keep these roles separate. We believe that separating these positions allows our Chief Executive Officer to focus on our day-to-day business, while allowing the chairperson of the board to lead the board of directors in its fundamental role of providing advice to and independent oversight of management. Our board of directors recognizes the time, effort, and energy that the Chief Executive Officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our chairperson, particularly as the board of directors' oversight responsibilities continue to grow. While our bylaws and our corporate governance guidelines do not require that our chairperson and Chief Executive Officer positions be separate, our board of directors believes that having separate positions is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance. In March 2024, our board of directors appointed Felix J. Baker as the Lead Independent Director of the board of directors. The Lead Independent Director's responsibilities may include, but are not limited to, calling and presiding over meetings of the independent directors, working with the chairperson of the board to establish the board of directors' meeting schedules and agendas, periodically meeting with independent directors, and meeting with the Chief Executive Officer regarding science and technology, development and strategy.

In March 2026, our Nominating and Corporate Governance Committee recommended that Dr. Baker be appointed as Chairman of our board of directors in place of Bruce Booth. The Board intends to appoint Dr. Baker as Chairman of our board of directors following the annual meeting on June 24, 2026. Dr. Baker is an independent director and therefore our board of directors has decided that, if Dr. Baker is appointed as Chairman, there will no longer be a separate Lead Independent Director. Dr. Booth plans to remain on the board of directors.

Risk is inherent to every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our financial condition, development and commercialization activities, operations, strategic direction and intellectual property. Management is responsible for the day-to-day management of risks we face, while our board of directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

The role of the board of directors in overseeing the management of our risks is conducted primarily through committees of the board of directors, as disclosed in the descriptions of each of the committees above and in the charters of each of the committees. The full board of directors (or the appropriate board committee in the case of risks that are under the purview of a particular committee) discusses with management our major risk exposures, their potential impact on us, and the steps we take to manage them. When a board committee is responsible for evaluating and overseeing the management of a particular risk or risks, the chairperson of the relevant committee reports on the discussion to the full board of directors during the committee reports portion of the next board meeting. This enables the board of directors and its committees to coordinate the risk oversight role, particularly with respect to risk interrelationships.

**Communication with the Directors of Kymera Therapeutics** 

Any interested party with concerns about our company may report such concerns to the board of directors or the chairperson of our board of directors, by submitting a written communication to the attention of such director at the following address:

c/o Kymera Therapeutics, Inc.

500 North Beacon Street, Fourth Floor

Watertown, Massachusetts 02472

United States

You may submit your concern anonymously or confidentially by postal mail. You may also indicate whether you are a shareholder, customer, supplier or other interested party.

A copy of any such written communication may also be forwarded to Kymera Therapeutics' Chief Legal Officer and a copy of such communication may be retained for a reasonable period of time. The director may discuss the matter with Kymera Therapeutics' legal counsel, with independent advisors, with non-management directors, or with Kymera Therapeutics' management, or may take other action or no action as the director determines in good faith, using reasonable judgment and applying his or her own discretion.

Communications may be forwarded to other directors if they relate to important substantive matters and include suggestions or comments that may be important for other directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications.

The Audit Committee oversees the procedures for the receipt, retention, and treatment of complaints received by Kymera Therapeutics regarding accounting, internal accounting controls, or audit matters, and the confidential, anonymous submission by employees of concerns regarding questionable accounting, internal accounting controls or auditing matters. Kymera Therapeutics has also established a third-party website, <u>https://www.whistleblowerservices.com/kymeratx</u>, and toll-free telephone number, (877) 306-2141, for the reporting of such activity.

**COMPENSATION DISCUSSION AND ANALYSIS** 

Our Compensation Committee is responsible for reviewing and approving, or recommending for approval by the board of directors, the compensation of our named executive officers, including base salary, cash and equity incentive compensation levels, severance arrangements, change-in-control benefits and other forms of executive compensation. This committee is also responsible for evaluating our company's performance against its goals and making related recommendations to our board of directors, assessing the performance of our named executive officers, and ensuring our compensation program is aligned with the objectives described below and competitive with those of other companies in our industry that compete with us for talent. Additionally, the Compensation Committee will engage on strategic, holistic talent topics beyond compensation including equity strategy and management, leadership development, succession planning and organizational engagement. This section discusses the principles underlying our Compensation Committee's policies and decisions with respect to the compensation of our named executive officers.

For 2025, our named executive officers were as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Nello Mainolfi, Ph.D., our Founder, President and Chief Executive Officer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Bruce Jacobs, CFA, MBA, our Chief Financial Officer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Jared Gollob, M.D., our Chief Medical Officer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Noah Goodman, MBA, our Chief Business Officer; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Brian Adams, J.D., our Chief Legal Officer

The following discussion should be read together with the compensation tables and related disclosures set forth below.

**Fiscal Year 2025 Performance Highlights and Achievement of 2025 Corporate Goals** 

**Business Overview**<br>

We are a clinical-stage biopharmaceutical company dedicated to reinventing the treatment of human disease through the development of innovative, highly differentiated oral medicines that address significant health problems and meaningfully improve patients' lives. We are committed to advancing novel technologies to address targets that have known disease-causing biology, but which have not been drugged, or have been inadequately drugged, often based on limitations of existing technologies. Our approach is intended to discover and develop a new generation of medicines in a disease-agnostic manner.

We are a leader in targeted protein degradation, or TPD, a next-generation small molecule therapeutic modality that engages the body's natural cellular recycling system to selectively eliminate disease-causing proteins.

Our current discovery and development efforts are primarily directed at high-value targets in immunology. We believe there are more than 160 million patients in the United States, Europe and Japan that are diagnosed with some of the most prevalent immune-inflammatory diseases that our programs have the potential to address, nearly half of whom remain untreated. We believe we have the potential to deliver a compelling value proposition to a significant underserved patient population: small molecule medicines with biologics-like activity through the convenience of a daily, oral pill.

Our publicly disclosed, wholly-owned immunology programs target STAT6 and IRF5, both of which are targets within validated pathways, providing the opportunity to treat a broad range of diseases. We have partnerships around two other disclosed targets, IRAK4 with Sanofi and CDK2 with Gilead. Our additional early undisclosed pipeline programs focus on addressing high impact targets that have been elusive to conventional modalities and that drive the pathogenesis of multiple serious diseases with significant unmet medical needs.

In addition to our immunology focus, we also have research initiatives in other therapeutic areas. Additionally, we believe many of our key discovery and development capabilities have broad applicability, creating an opportunity for us to develop impactful therapies leveraging small-molecule modalities in addition to TPD.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪We ended 2025 with cash, cash equivalents and marketable securities of approximately $1.6 billion.

**Corporate Goals and Achievements**<br>

Annually, we establish corporate goals, a subset of which are publicly announced, that are intended for the upcoming calendar year. Collectively, the publicly disclosed goals, and those maintained internally, form the company's overall corporate goals. The company often realizes achievements that were not specifically stated in the corporate goals, but which are nonetheless important accomplishments, and those are also considered in evaluating management's performance. Our 2025 corporate goals were considered by our management and our Compensation Committee in their respective assessment of the company's performance for 2025. As described in more detail below in "Primary Elements of Executive Compensation" and "Annual Cash Incentive Compensation," based on an evaluation of our performance in 2025 and input from our Compensation Committee, our board of directors established a bonus payout ratio of 125% of target due to achievement of our corporate goals for 2025 and in recognition of our additional successes beyond our stated corporate goals.

Our goals were centered around those that supported the development and advancement of our pipeline (65% weighting) and those that supported our company growth (35% weighting). A summary of some of our key goals in each category is shown below:

------

**<u>Development and Advancement of Pipeline (65% weighting)</u>**

**Consideration of Say-On-Pay Advisory Vote** 

Based on shareholder and board approvals, we have adopted an annual "Say-on-Pay" vote. During the 2024 and 2025 annual meetings, 94% and 88% of our shareholders' votes expressed support for our named executive officer compensation, respectively. Although this is a non-binding advisory vote, because we value the opinion of our shareholders, our board of directors and our Compensation Committee will consider the outcome of the "Say-on-Pay" vote as well as feedback received throughout the year, when making compensation determinations for our executive officers in the future.

**Total Rewards and Talent Philosophy** 

Our shared values and deep commitment to improving patients' lives are the guiding principles that drive our work and connect our diverse and experienced teams to the company's mission. We strive to create an environment that empowers and inspires our employees and believe that our total rewards strategy should align strongly with our organizational strategy, vision, and values. We aim to recognize results and capabilities, designing compensation programs that reflect market-based, performance driven pay and appropriately reward our people for their contributions. Our broader talent strategy and approach strives to fully engage our people by creating experiences and incentives that demonstrate how much we value our employees on an individual level. All our investments reflect a holistic view of rewards, inspiring people to do more for patients and creating commitment to achieving our goals, thereby helping our company succeed in its objective to become a fully integrated biopharmaceutical company. Beyond total rewards we prioritize values-based talent initiatives that reinforce our culture, maximize employee engagement and create opportunities for people to learn and grow in a fast-paced, results-oriented environment. These efforts include leadership development, manager training, succession planning and cultural programs.

To achieve these objectives, our Compensation Committee evaluates our strategic total rewards programs and engages in talent discussions annually. They provide input and make changes periodically as business and market circumstances are warranted, with the goal of aligning our total rewards and strategic talent initiatives with our philosophy outlined above. Our Compensation Committee also engaged Alpine Rewards, or Alpine, an independent compensation advisor, to evaluate size, development stage, and compensation practices of peer biopharmaceutical companies and the talent market, including the availability of, and demand for, particular skills and expertise when making recommendations.

**Executive Compensation Program Overview** 

Our Compensation Committee believes that the most effective compensation program is one that promotes company performance, rewards value creation for shareholders and progress towards achieving our mission. Our committee targets key elements of our executive compensation program as follows, which are described in more detail below in "Primary Elements of Executive Compensation:"

| | | | |
|:---|:---|:---|:---|

As seen above, our Compensation Committee includes "at-risk" incentives as the majority of executive compensation. By doing this, our named executive officers, or NEOs, have a significant stake in Kymera's success which creates direct alignment with shareholder interest. The below chart outlines at a high level such alignment in action as 92% of CEO pay and, on average, 86% of NEOs pay in 2025 was "at-risk."

![img50301753_1.jpg](img50301753_1.jpg)

In addition to our direct compensation elements, the following features of our executive compensation program are designed to align with shareholder interests and market best practices:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;**What We Do** | **What We Don't Do** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;✓ Maintain an industry-specific and size-appropriate peer group for benchmarking compensation<br>✓ Annually assess competitiveness of compensation opportunities and design against the market<br>✓ Deliver executive compensation primarily through variable, performance-based, and at-risk pay<br>✓ Set challenging corporate goals and revisit those goals periodically based on year-to-date progress, to ensure they remain challenging<br>✓ Offer market-competitive benefits to executives that are consistent with the rest of our employees<br>✓ Consult with an independent compensation consultant on compensation levels and practices<br>✓ Maintain annual say-on-pay vote for shareholders to comment on executive compensation<br>✓ Use double trigger change-in-control protection for our executive officers with limited exceptions<br>✓ Maintain thorough governance features including anti-pledging and anti-hedging policies<br>✓ Maintain an independent Compensation Committee<br>✓ Adopted a compensation recovery (or "clawback") policy, which requires recovery from current and former executive officers of certain incentive-based compensation in the event of a required restatement of previously issued financial restatements | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;✗ No automatic or guaranteed annual salary increases, annual cash incentive payments or long-term equity incentive awards<br>✗ No hedging, pledging, short selling or margin calls of equity<br>✗ No backdating of equity incentive awards<br>✗ No excessive perquisites to our executive officers<br>✗ No supplemental executive retirement plans or special health and welfare benefits are provided to our executive officers<br>✗ No tax gross-ups in executive agreements<br>✗ No stock option repricing absent shareholder approval |

---

We believe that targeting overall compensation in this manner is necessary and appropriate in order to align our executive pay practices to individual and corporate performance, attract and retain the quality of talent we need to successfully grow our business, achieve our challenging goals, and ensure that compensation levels are competitive with those of other companies against which we compete for talent. In addition, we believe this approach to overall compensation creates a strong alignment with shareholder value and encourages long-term value creation.

While we stay committed to these guidelines, any given individual employee's compensation may vary from the targeted pay framework, based on the unique responsibilities and requirements of his or her position, his or her experience and other qualifications, internal parity relative to similar positions within our company, and individual or

------

company performance relative to performance goals and the peer group to ensure appropriate pay-for-performance alignment.

**Primary Elements of Executive Compensation** 

***Base Salary*** 

Each named executive officer's base salary is a fixed component of annual compensation for performing specific duties and functions and has been established by our Compensation Committee or board of directors, as applicable, and reviewed annually typically in connection with our annual performance review process and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience.

None of our named executive officers is currently party to an employment agreement or other agreement or arrangement that provides for automatic or scheduled increases in base salary. However, on an annual basis, our Compensation Committee reviews and evaluates, taking into account recommendations from our Chief Executive Officer (with respect to executive officers other than himself), the need for adjustment of the base salaries of our executive officers. Our Compensation Committee also reviews and evaluates, without input from our Chief Executive Officer, the need for adjustment of the base salary of our Chief Executive Officer. In each case, changes and expected changes in the scope of an executive officer's responsibilities, including promotions, the individual contributions made by and performance of the executive officer during the prior year, our overall growth and development as a company and general salary or other market trends in our industry are taken into account.

In January 2025, our Compensation Committee approved the following 2025 salary increases for each of our named executive officers based on a review of our 2025 peer group market data provided by Alpine, macroeconomic factors such as inflation, the current compensation levels of our named executive officers, and an assessment of 2024 performance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)All fiscal year 2025 base salaries first became effective on January 1, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Mr. Goodman joined the company as our Chief Business Officer on April 8, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)Mr. Adams joined the company as our Chief Legal Officer on September 3, 2025.

***Annual Cash Incentive Compensation*** 

Our board of directors has adopted a senior executive cash incentive bonus plan, or the executive bonus plan, which is an annual bonus program intended to reward our named executive officers for meeting objective or subjective performance goals for a fiscal year. The executive bonus plan provides for cash payments based upon the attainment of performance targets established by the Compensation Committee, which may relate to financial and operational measures or objectives, as well as individual performance objectives. Each executive officer who is selected to participate in the executive bonus plan will have a target bonus opportunity set for each performance period. We believe this executive bonus plan provides incentive that motivates and rewards achievement of performance goals that directly correlates to enhancement of shareholder value, consistent with our total rewards philosophy. Subject to the rights contained in any agreement between the executive officer and the company, an executive officer must be employed by the company on the bonus payment date to be eligible to receive a bonus payment. Each of our named executive officers is eligible to participate in the executive bonus plan.

------

In December 2025, the Compensation Committee reviewed the performance of the annual goals set at the beginning of 2025. In light of the company's significant achievements in 2025, the Compensation Committee recommended a bonus payout of 125% of target. Our Compensation Committee also evaluates the individual performance of our named executive officers, with the input of our Chief Executive Officer in the case of the evaluation of our other named executive officers and makes recommendations to our board of directors with regard to the evaluation of our Chief Executive Officer's individual performance. Individual performance is considered for purposes of determining any positive or negative adjustments to an officer's bonus for the applicable year. Consistent with this process, our Compensation Committee assessed the performance of Dr. Mainolfi in 2025 based on our relative achievement of our corporate goals as well as his leadership in driving the execution of our strategic plans. The Compensation Committee determined each of the other named executive officer's performance in 2025 by considering each officer's individual contributions to the completion of our corporate goals and the officer's individual achievements in executing our strategy and respective functional objectives.

Based on its assessment of corporate and individual performance, our board of directors approved, upon the recommendation of the Compensation Committee, a bonus multiplier of 125% of target award opportunity for the 2025 cash incentive payment for our Chief Executive Officer and each of our other named executive officers.

(1) Target bonus opportunities and actual annual incentive payments for Messrs. Goodman and Adams were prorated to reflect their respective start dates in 2025.

***Long-Term Equity Incentive Awards*** 

Equity compensation represents the largest at-risk component of our named executive officers' compensation arrangements. We believe that it is appropriate to align the interests of our named executive officers with those of our shareholders to achieve and sustain long-term value creation and stock price appreciation. We use stock options, or an equity mix of stock options and restricted stock units to compensate our executive officers in the form of initial grants in connection with the commencement of employment. In addition to initial grants, named executive officers are also eligible for annual grants in the form of stock options, restricted stock units, and performance stock units . Initial equity awards are typically granted to our executive officers upon the commencement of their employment, and any annual equity awards granted to executive officers are typically granted effective in the first quarter of the year following the applicable performance period. Any stock options granted to our executive officers will have an exercise price equal to the closing price of our common stock as reported on the Nasdaq Global Market on the date of grant, and have time-based vesting over multiple years and will expire ten years after the date of grant. Restricted stock units will have time-based vesting over multiple years starting from the date of grant.

For annual grants, our Chief Executive Officer receives a combination of time-based and performance-based stock options, and performance stock units, and the remainder of our named executive officers receive a blend of stock options, restricted stock units, and performance stock units, to better align with shareholder interests. When determining equity incentive compensation for our named executive officers for 2025, our Compensation Committee, with assistance from Alpine, considers a variety of factors in comparison to our named peers, including the following: annual long-term incentive target values, annual equity awards expressed as a percentage of total shares outstanding, total annual and cumulative dilution, the retentive value of outstanding awards and total equity ownership and the equity compensation practices of other companies in our industry that compete with us for talent. Given the dynamic biopharmaceutical market, the Compensation Committee does not overemphasize any one perspective. Rather, the committee takes a holistic perspective, further considering the factors enumerated above, the achievement of our

------

company goals and how that impacts total shareholder return, as well as executive performance, when determining actual award levels for the named executive officers, which the committee generally targets up to the 55<sup>th</sup> percentile of our peer group for time-based equity with performance-based equity enabling higher market positioning based on future long-term goal achievement. Accordingly, our Compensation Committee and board of directors periodically review the equity incentive compensation of our named executive officers and from time to time may grant equity incentive awards to them in the form of stock options and restricted stock units.

The initial stock option awards granted to executive officers upon commencement of their employment vest as to 25% of the shares underlying the award on the first anniversary of the grant date and as to an additional 1/48<sup>th</sup> of the shares underlying the award monthly thereafter, subject to the executive officer's continued employment. Restricted stock units granted upon commencement of employment vest at a rate of 25% on the first anniversary of the grant date and an additional 25% annually thereafter. The annual stock option awards granted to executive officers vest in equal monthly installments over a three-year vesting period, subject to the executive officer's continued employment. Annual restricted stock unit awards granted vest in equal annual installments over a three-year vesting period, starting on the first anniversary of the date of grant, subject to the executive officer's continued employment.

Upon termination of employment, vesting for any equity awards granted to executive officers will cease and option exercise rights will generally cease three months thereafter. In specified termination and change-in-control circumstances, equity awards held by our named executive officers are subject to accelerated vesting. See "Employment, Severance and Change-in-Control Arrangements" below for further information.

In March 2025, our Compensation Committee granted time-based and performance-based stock options, and performance stock units to our Chief Executive Officer and a mix of stock options, restricted stock units, and performance stock units to our other named executive officers in the amounts set forth in the table below, generally aligning competitive equity award time-based grants up to the 55<sup>th</sup> percentile of our peer group, with additional opportunity to achieve higher market positioning provided in the form of performance options or performance stock units. With all grants, variation is applied based on individual and company performance, in recognition of achievements and performance during 2024 and for expected continued contributions over the equity vesting period.

***Go-Forward Changes to 2026 Compensation Programs*** 

Starting in 2026, all named executive officers, including our Chief Executive Officer, will have their time-based stock option and restricted stock units vest over a four-year period, an increase from the prior three-year vesting schedule. This change is intended to support long-term retention and further align executive interest with those of our shareholders. In addition, in 2025, our Chief Executive Officer received the performance-based portion of his equity grants in the form of both performance-based stock options and performance stock units. Finally, in 2026, all of our performance-based equity awards will include a component of rTSR to further strengthen alignment with shareholder interests.

------

***Other Benefits*** 

Other compensation to our executives consists primarily of competitive and broad-based benefits we offer to all regular full-time employees. Named executive officers are eligible to participate in all our employee benefit plans, in each case on the same basis as other employees. We do not offer any defined benefit pension plans or nonqualified deferred compensation arrangements for our employees, including our named executive officers. We may offer cash retention awards to our employees, including our named executive officers, for long-term retention, and consider various factors, including the availability of, and demand for, particular knowledge, skills and expertise.

*401(k) Plan.* We participate in a retirement savings plan, or 401(k) plan, that is intended to qualify for favorable tax treatment under Section 401(a) of the Internal Revenue Code, or Code, and contains a cash or deferred feature that is intended to meet the requirements of Section 401(k) of the U.S. Internal Revenue Code of 1986, as amended, or the Code. U.S. employees who are at least 21 years of age are generally eligible to participate in the 401(k) plan, subject to certain criteria. We have implemented a safe harbor match under our 401(k) plan of 100% of the first 3% and 50% of the next 2%, for a total match of 4% of the first 5%. Participants may make pre-tax and certain after-tax (Roth) salary deferral contributions to the plan from their eligible earnings up to the statutorily prescribed annual limit under the Code. Participants who are 50 years of age or older may contribute additional amounts based on the statutory limits for catch-up contributions. Participant contributions are held in trust as required by law. An employee's interest in his or her salary deferral contributions is 100% vested when contributed. We have the ability to make discretionary contributions under the plan but did not make any contributions in 2025.

*Health and Welfare Benefits.* All of our named executive officers, are eligible to participate in all of our employee benefit plans, including our medical, dental and vision insurance, health savings and dependent care flexible spending accounts, group life, voluntary life and disability insurance, on the same basis as other employees. We also offer wellness incentives, commuting benefits, paid time-off benefits and holidays.

*Employee Stock Purchase Plan.* Pursuant to our employee stock purchase plan, employees, including our named executive officers, have an opportunity to purchase our common stock at a discount on a tax-qualified basis through payroll deductions. The employee stock purchase plan is designed to qualify as an "employee stock purchase plan" under Section 423 of the Code. The purpose of the employee stock purchase plan is to encourage our employees, including our named executive officers, to become our shareholders and better align their interests with those of our other shareholders.

*Perquisites*. We do not provide perquisites or personal benefits to our named executive officers.

*Severance Benefits.* We offer our executives severance benefits upon an involuntary or constructive termination based in part on market practice for similarly situated companies, as we believe such post-employment compensation protections are appropriate in light of similar benefits available to executive officers at companies in our peer group. We also offer our executives additional severance benefits in connection with change-in-control situations. We believe that reasonable and competitive change-in-control payments and benefits are an important part of an executive compensation program to attract and retain senior executives. We also believe such payments and benefits are in the best interests of our shareholders because they incentivize senior executives to continue to strive to achieve shareholder value in connection with change-in-control situations, particularly where the possibility of a change-in-control and the related uncertainty may lead to the departure or distraction of senior executives to the detriment of our company and our shareholders. A description of these arrangements is set forth under the subsection titled "Employment, Severance and Change-in-Control Arrangements" below, and information on the estimated payments and benefits that our named executive officers would have been eligible to receive as of December 31, 2025, is set forth in the subsection titled "Potential Payments Upon Termination or Change in Control" below.

------

**Governance of Executive Compensation Program** 

***Role of Our Compensation Committee and Board of Directors*** 

Our board of directors and Compensation Committee annually review compensation for our executive officers. In determining executive base salaries, annual cash incentive compensation and long-term equity incentive compensation, the Compensation Committee and our board of directors consider compensation for comparable positions in the market, the historical compensation levels of our executives, individual performance as compared to our expectations and objectives, our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our shareholders, and a long-term commitment to our company. We target a general competitive position, considering market data as well as internal factors and market conditions to inform the magnitude and mix of compensation of base salary, annual cash incentive compensation and/or equity incentive grants.

Our Compensation Committee is responsible for determining the compensation for all executive officers other than our Chief Executive Officer. Our board of directors, with the recommendation of the Compensation Committee, is responsible for determining the compensation of our Chief Executive Officer. Our Compensation Committee typically reviews and discusses management's proposed compensation with the Chief Executive Officer for all executive officers other than the Chief Executive Officer. Based on those discussions and its discretion, taking into account the factors noted above, the Compensation Committee then sets the compensation for each executive officer other than the Chief Executive Officer and recommends the compensation for the Chief Executive Officer to our board of directors for approval. Our board of directors discusses the Compensation Committee's recommendation and ultimately approves the compensation of our Chief Executive Officer.

***Role of the Compensation Consultant*** 

In fiscal year 2025, our Compensation Committee continued to retain the services of Alpine Rewards as its external compensation consultant and considered Alpine's input on certain compensation matters as they deemed appropriate. Our Compensation Committee requires that its compensation consultants be independent of management and performs an annual assessment of the compensation consultants' independence to determine whether the consultants are independent. Our Compensation Committee performed this assessment in 2025 and determined that Alpine is independent pursuant to the listing standards of the relevant Nasdaq and SEC rules and has concluded that the engagement of Alpine did not raise any conflict of interest.

***Role of Management*** 

Our Compensation Committee works with our management, including our Chief Executive Officer, in making compensation determinations. Our management assists our Compensation Committee by providing information on corporate and individual performance, market compensation data and management's perspective on compensation matters.

In addition, our Chief Executive Officer reviews the performance of our other named executive officers multiple times throughout the year, including at the end of each year, based on our achievement of our corporate goals and each executive officer's achievement of his or her functional and individual goals established for the year and his or her overall performance during that year. Our Compensation Committee reviews our Chief Executive Officer's recommendations for base salary increases, annual cash incentive compensation, long-term equity incentive grants and any other compensation opportunities for our other named executive officers and considers our Chief Executive Officer's recommendations in determining such compensation.

***Defining and Comparing Compensation to Market Benchmarks*** 

In evaluating the total compensation of our named executive officers, our Compensation Committee, using information provided by Alpine in 2024 for fiscal year 2025, establishes a peer group of publicly traded companies in the biopharmaceutical and biotechnology industries that is selected based on a balance of the following criteria:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•companies whose number of employees, development stage, therapeutic focus, market capitalization, and tenure as a public company are similar, though not necessarily identical to ours;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•companies with similar executive positions to ours;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•companies against which we believe we compete for executive and employee talent; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•public companies generally based in the United States whose compensation and financial data are available in proxy statements or through widely available compensation surveys.

Based on these criteria, our 2025 peer group, as approved by our Compensation Committee was comprised of the following 18 companies:

---

| | | |
|:---|:---|:---|
| ApogeeTherapeutics | Denali Therapeutics | Protagonist Therapeutics |
| Arcellx | Dyne Therapeutics | Revolution Medicines |
| Arvinas | IDEAYA Biosciences | Scholar Rock |
| Avidity Biosciences | ImmunityBio | Vaxcyte |
| Beam Therapeutics | Immunovant | Vera Therapeutics |
| Biohaven | Nuvalent | Viking Therapeutics |

---

The Compensation Committee believes the compensation practices of our 2025 peer group provided us with appropriate compensation data for evaluating the compensation of our named executive officers. Any changes or removals for the 2025 peer group were driven by peer companies falling outside the desired criteria for market cap, headcount and/or stage of development. Notwithstanding any potential similarities we may have with our 2025 peer group, due to the nature of our business, we compete for executive talent with many public companies that are larger and more established than we are or that possess greater resources than we do, and with smaller private companies that may be able to offer greater equity compensation potential, as well as with prestigious academic and non-profit institutions.

For purposes of compensation for fiscal year 2026, our Compensation Committee, with the advice of Alpine, examined our 2025 peer group. In addition, with reference to number of employees, development stage, therapeutic area, market capitalization and other key business metrics, as well as whether the companies in our 2025 peer group experienced reduced growth or change in market capitalization, our Compensation Committee approved the following 18 companies as our 2026 peer group:

---

| | | |
|:---|:---|:---|
| ApogeeTherapeutics | Denali Therapeutics | Protagonist Therapeutics |
| Arcellx | Dyne Therapeutics | Revolution Medicines |
| Avidity Biosciences | IDEAYA Biosciences | Scholar Rock |
| Beam Therapeutics | ImmunityBio | Vaxcyte |
| Biohaven | Immunovant | Vera Therapeutics |
| CRISPR Therapeutics\* | Nuvalent | Viking Therapeutics |

\* New addition to our 2026 peer group

***Compensation Policies and Practices*** 

*Anti-Hedging and Pledging Policy.* Our insider trading policy expressly prohibits all of our employees, including our named executive officers, as well as our directors, from engaging in speculative transactions in our stock, including buying our securities on margin, borrowing against our securities held in a margin account, engaging in short sales of our securities, and buying or selling derivatives on our securities. Our insider trading policy generally prohibits all of our employees, including our named executive officers, as well as our directors, from pledging our securities as collateral for a loan. To date, no requests for any waivers of these policies have been made or approved.

*Compensation Recovery Policy.* Our board of directors adopted a compensation recovery policy. The compensation recovery policy generally provides, subject to certain exceptions, that if the company is required to prepare a restatement of its financial statements, the company will recover from its executive officers any incentive-based compensation that was erroneously awarded in excess of the amount that otherwise would have been awarded based on restated amounts in the restated financial statements. The recovery period is the three completed fiscal years immediately preceding the date that our board of directors concludes that the company is required to restate its financial statements. Incentive-based compensation includes any compensation that is granted, earned, or vested based on the attainment of a financial reporting measure of the company.

------

The preceding description of our compensation recovery policy is qualified by the policy itself, which was filed as Exhibit 97 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

*No Tax Gross-ups.* We do not provide for any tax gross-up payments in the employment agreements of our named executive officers.

*Accounting Considerations.* We account for equity compensation paid to our employees under the rules of the Financial Accounting Standards Board Accounting Standards Codification Topic 718, or FASB ASC Topic 718, which rules require us to estimate and record an expense over the service period of any such award. Accounting rules also require us to record cash compensation as an expense at the time the obligation is accrued. To date, these accounting requirements have not impacted our executive compensation programs and practices.

*Tax Considerations for Deductibility of Executive Compensation.* Section 162(m) of the Code, or Section 162(m), generally limits to $1 million the deduction that a public company could claim in any tax year with respect to compensation paid to anyone serving as the Chief Executive Officer, the Chief Financial Officer, and the top three other most highly compensated officers, and once an executive becomes a "covered employee" under Section 162(m), the individual will continue to be a "covered employee" as long as he or she remains employed by the company. In designing our executive compensation program and determining the compensation of our executive officers, including our named executive officers, our Compensation Committee considers a variety of factors, including the potential impact of the Section 162(m) deduction limit. However, to maintain flexibility to compensate our executive officers in a manner designed to promote our short-term and long-term corporate goals, our Compensation Committee has not adopted a policy that all compensation must be deductible. Our Compensation Committee believes that our shareholders' interests are best served if its discretion and flexibility in awarding compensation is not restricted, even though some compensation awards may result in non-deductible compensation expense.

*Taxation of "Parachute" Payments and Deferred Compensation.* Sections 280G and 4999 of the Code provide that executive officers and directors who hold significant equity interests and certain other service providers may be subject to significant additional taxes if they receive payments or benefits in connection with a change in control of the company that exceeds certain prescribed limits, and that the company (or a successor) may forfeit a deduction on the amounts subject to this additional tax. Section 409A of the Code imposes additional significant taxes in the event that an executive officer, director or service provider receives "deferred compensation" that does not satisfy the requirements of Section 409A of the Code. We have not agreed to provide any executive officer, including any named executive officers, with a "gross-up" or other reimbursement payment for any tax liability that the executive officer might owe as a result of the application of Sections 280G, 4999 or 409A of the Code.

**Compensation Risk Assessment** 

We believe that although a portion of the compensation provided to our named executive officers and other employees is performance-based, our executive compensation program does not encourage excessive or unnecessary risk taking. Our compensation programs are designed to encourage our named executive officers and other employees to remain focused on both short-term and long-term strategic goals, in particular in connection with our pay-for-performance compensation philosophy. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us.

(1) The amounts reported in the Stock Awards column represent the aggregate grant date fair value for the fiscal years ended December 31, 2025, 2024, and 2023 of grants of time based and performance based restricted stock units awards to each of the NEOs, calculated in accordance with FASB ASC Topic 718. For each performance based restricted stock units awards, the grant date fair value, based on probable achievement of the applicable performance metrics, was $0. Assuming maximum achievement of the applicable performance conditions, the grant date fair value of such awards would have been $1,327,480 for Dr. Mainolfi, $980,525 for Mr. Jacobs and $980,525 for Dr. Gollob. See Note 2 to the financial statements in our Annual Report on Form 10-K for the year ended December 31, 2025 regarding assumptions we made in determining the fair value of restricted stock units awards.

(2) The amounts reported in the Option Awards column represent the aggregate grant date fair value for grants of time based and performance based stock options awards, calculated in accordance with FASB ASC Topic 718. For performance based stock options, the grant date fair value, based on probable achievement of the applicable performance metrics, was $0. Assuming maximum achievement of the applicable performance conditions, the grant date fair value of such awards would have been $1,791,747 for Dr. Mainolfi. See Note 2 to the financial statements in our Annual Report on Form 10-K for the year ended December 31, 2025 regarding assumptions we made in determining the fair value of option awards.

(3) The amounts reflect the 401(k) employer matching contribution made on account of the respective years.

**Narrative to Summary Compensation Table** 

***Salary*** 

Amounts represent the actual amount of base salary paid for each NEO during each applicable year. NEOs and other employees are generally assessed for potential salary increases to be made effective at the beginning of each year. Percentage salary increases for each of our NEOs were approved in January 2025 as follows: Dr. Mainolfi (3.4% to $693,000), Mr. Jacobs (4% to $500,000), and Dr. Gollob (3.5% to $507,100). For more information, see the discussion for each NEO under "Primary Elements of Executive Compensation" above.

------

***Option Awards*** 

The amounts reported represent the aggregate grant date fair value of the stock options awarded to the NEOs during each applicable year, calculated in accordance with FASB ASC Topic 718. Such grant date fair values do not take into account any estimated forfeitures. The assumptions used in calculating the grant date fair value of the stock options reported in this column are set forth in Note 2 to the financial statements in our Annual Report on Form 10-K for the year ended December 31, 2025. The amounts reported in this column reflect the accounting cost for these stock options and do not correspond to the actual economic value that may be received by the NEOs upon the exercise of the stock options or any sale of the underlying shares of common stock. The amounts shown reflect annual equity awards to the NEOs and, in the case of Mr. Adams and Mr. Goodman, the 2025 amounts reflect initial equity (or new hire) grants.

***Stock Awards*** 

The amount reported represents the aggregate grant date fair value of restricted stock units awarded to the NEOs, calculated in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 718. Such grant date fair value does not take into account any estimated forfeitures. The assumptions used in calculating the grant date fair value of the restricted stock units reported in this column are set forth in Note 2 to the financial statements in our Annual Report on Form 10-K for the year ended December 31, 2025. The amount reported in this column reflects the accounting cost for these equity awards and does not correspond to the actual economic value that may be received by the applicable NEO upon the vesting/settlement of the restricted stock units or any sale of the underlying shares of common stock. The award amounts reflect annual equity awards for all NEOs and, in the case of Mr. Adams and Mr. Goodman, the 2025 amounts reflect initial equity (or new hire) grants.

***Non-Equity Incentive Plan Compensation*** 

The amounts reported represent annual bonuses earned by our NEOs for services performed during the fiscal years indicated, as applicable, based on the achievement of company and individual performance objectives. Target bonuses for our NEOs are set as a percentage of annual salary, and for 2025 were 60% of salary for Dr. Mainolfi (CEO), and 45% of salary for our other NEOs. Mr. Adams and Mr. Goodman were both hired in 2025 and, as a result, their respective annual bonuses for 2025 were prorated.

(1) The value realized when the stock options were exercised represents (i) the excess of the closing price of a share of our common stock as reported on the Nasdaq Global Market on the date of exercise over the per share exercise price of the stock option, multiplied by (ii) the number of option shares exercised.

(2) The value realized upon vesting of restricted stock awards or restricted stock units is calculated by multiplying the number of restricted stock units vested by the closing price market price of a share of our common stock as reported on the Nasdaq Global Market on the vest date.

**Employment, Severance and Change-in-Control Arrangements** 

We entered into employment agreements with each of Dr. Mainolfi, Mr. Jacobs, Dr. Gollob, Mr. Goodman and Mr. Adams that provide for specified payments and benefits in connection with a termination of employment in certain circumstances. Our goal in providing this severance and change in control payments and benefits is to offer sufficient cash continuity protection such that the named executive officers will focus their full time and attention on the requirements of the business rather than the potential implications for their respective positions. We prefer to have certainty regarding the potential severance amounts payable to the named executive officers, rather than negotiating severance at the time that a named executive officer's employment terminates. We have also determined that accelerated vesting provisions with respect to outstanding equity awards in connection with a qualifying termination of employment in certain circumstances are appropriate because they encourage our named executive officers to stay focused on the business in those circumstances, rather than focusing on the potential implications for them personally. The employment agreements with our named executive officers will require the named executive officers to execute a separation agreement containing a general release of claims in favor of us to receive any severance payments and benefits. The material terms of our employment agreements with our named executive officers are summarized below.

***Nello Mainolfi, Ph.D.*** 

Under the employment agreement we entered into with Dr. Mainolfi in August 2020, or the Mainolfi Employment Agreement, Dr. Mainolfi serves as our Founder, President and Chief Executive Officer on an at-will basis. Dr. Mainolfi's 2025 annual base salary was $693,000 which was subject to periodic review and adjustment, and he was eligible to earn an annual bonus with a target amount equal to 60% of his base salary. Dr. Mainolfi was also eligible to participate in the employee benefit plans available to our employees, subject to the terms of those plans.

Pursuant to the Mainolfi Employment Agreement, in the event that his employment is terminated by us without "cause" or Dr. Mainolfi resigns for "good reason" (as each term is defined in the Mainolfi Employment Agreement), subject to the execution and effectiveness of a separation agreement, including a general release of claims in our favor,

------

(i) he will be entitled to receive base salary continuation for twelve (12) months following termination, (ii) subject to Dr. Mainolfi's copayment of premium amounts at the applicable active employees' rate and proper election to continue COBRA health coverage, we will cover the portion of the premium amount equal to the amount that we would have paid to provide health insurance to Dr. Mainolfi had he remained employed with us until the earliest of (A) twelve (12) months following termination, (B) Dr. Mainolfi's eligibility for group medical plan benefits under any other employer's group medical plan or (C) the end of Dr. Mainolfi's COBRA health continuation period, and (iii) acceleration of 25% of the unvested portion of all stock options and other stock-based awards subject solely to time-based vesting held by Dr. Mainolfi as of immediately prior to our initial public offering in August 2020.

In lieu of the payments and benefits described in the preceding sentence, in the event that Dr. Mainolfi's employment is terminated by us without cause or Dr. Mainolfi resigns for good reason, in either case within three (3) months prior to, on or within twelve (12) months following a "change in control" (as defined in the Mainolfi Employment Agreement), subject to the execution and effectiveness of a separation agreement, including a general release of claims in our favor, (i) he will be entitled to receive a lump sum in cash equal to 1.5 times the sum of (A) Dr. Mainolfi's then-current annual base salary (or Dr. Mainolfi's annual base salary in effect immediately prior to the change in control, if higher) plus (B) Dr. Mainolfi's target annual cash incentive compensation for the year of termination (or Dr. Mainolfi's target annual cash incentive compensation in effect immediately prior to the change in control, if higher), (ii) subject to Dr. Mainolfi's copayment of premium amounts at the applicable active employees' rate and proper election to continue COBRA health coverage, we will cover the portion of the premium amount equal to the amount that we would have paid to provide health insurance to Dr. Mainolfi had he remained employed with us until the earliest of (A) eighteen (18) months following termination, (B) Dr. Mainolfi's eligibility for group medical plan benefits under any other employer's group medical plan or (C) the end of Dr. Mainolfi's COBRA health continuation period, and (iii) 100% of all stock options and other stock-based awards subject solely to time-based vesting held by Dr. Mainolfi shall be accelerated.

The payments and benefits provided to Dr. Mainolfi in connection with a change in control may not be eligible for a federal income tax deduction for the company pursuant to Section 280G of the Code, and may subject Dr. Mainolfi to an excise tax under Section 4999 of the Code. If the payments or benefits payable to Dr. Mainolfi in connection with a change in control would be subject to the excise tax on golden parachutes imposed under Section 4999 of the Code, then those payments or benefits will be reduced if such reduction would result in a higher net after-tax benefit to Dr. Mainolfi.

***Other Named Executive Officers' Compensation*** 

***Bruce Jacobs, CFA, MBA***

Under the employment agreement we entered into with Mr. Jacobs in August 2020, Mr. Jacobs serves as our Chief Financial Officer on an at-will basis. Mr. Jacobs' 2025 annual base salary was $500,000 which was subject to periodic review and adjustment, and he was eligible to earn an annual bonus with a target amount equal to 45% of his base salary.

Mr. Goodman was also eligible to participate in the employee benefit plans available to our employees, subject to the terms of those plans.

------

Mr. Adams was also eligible to participate in the employee benefit plans available to our employees, subject to the terms of those plans.

***Other Named Executive Officers' Employment Agreements***

Pursuant to Mr. Jacobs', Dr. Gollob's, Mr. Goodman's and Mr. Adams' employment agreements, in the event that the named executive officer's employment is terminated by us without "cause" or the named executive officer resigns for "good reason" (as each term is defined in the named executive officer's employment agreement), subject to the execution and effectiveness of a separation agreement, including a general release of claims in our favor, the named executive officer will be entitled to receive (i) base salary continuation for nine (9) months following termination, and (ii) subject to the named executive officer's copayment of premium amounts at the applicable active employees' rate and proper election to continue COBRA health coverage, we will cover the portion of the premium amount equal to the amount that we would have paid to provide health insurance to the named executive officer had the named executive officer remained employed with us until the earliest of (A) nine (9) months following termination, (B) the named executive officer's eligibility for group medical plan benefits under any other employer's group medical plan or (C) the end of the named executive officer's COBRA health continuation period.

In lieu of the payments and benefits described in the preceding sentence, in the event that the named executive officer's employment is terminated by us without cause or the named executive officer resigns for good reason, in either case on or within twelve (12) months following a "change in control" (as defined in the named executive officer's employment agreement), subject to the execution and effectiveness of a separation agreement, including a general release of claims in our favor, (i) the named executive officer will be entitled to receive a lump sum in cash equal to one (1) times the sum of (A) the named executive officer's then-current annual base salary (or the named executive officer's annual base salary in effect immediately prior to the change in control, if higher) plus (B) the named executive officer's target annual cash incentive compensation for the year of termination (or the named executive officer's target annual cash incentive compensation in effect immediately prior to the change in control, if higher), (ii) subject to the named executive officer's copayment of premium amounts at the applicable active employees' rate and proper election to continue COBRA health coverage, we will cover the portion of the premium amount equal to the amount that we would have paid to provide health insurance to the named executive officer had the named executive officer remained employed with us until the earliest of (A) twelve (12) months following termination, (B) the named executive officer's eligibility for group medical plan benefits under any other employer's group medical plan or (C) the end of the named executive officer's COBRA health continuation period, and (iii) 100% of all stock options and other stock-based awards subject solely to time-based vesting held by the named executive officer shall be accelerated.

The payments and benefits provided to the named executive officer in connection with a change in control may not be eligible for a federal income tax deduction for the company pursuant to Section 280G of the Code and may subject the named executive officer to an excise tax under Section 4999 of the Code. If the payments or benefits payable to the named executive officer in connection with a change in control would be subject to the excise tax on golden parachutes imposed under Section 4999 of the Code, then those payments or benefits will be reduced if such reduction would result in a higher net after-tax benefit to the named executive officer.

***Potential Payments Upon Termination or Change-in-Control***

The amount of compensation and benefits payable to each named executive officer employed as of December 31, 2025 under our current employment agreements in various termination and/or change-in-control situations has been estimated in the table below, which assumes that such termination and/or change-in-control occurred on December 31, 2025 and that no non-competition provisions will be enforced following any such termination. The value of the equity vesting acceleration was calculated based on the assumption that the change-in-control and/or executive's employment termination occurred on December 31, 2025. For purposes of the following table, we have used $77.81 per share, which was the closing price of our common stock as reported on the Nasdaq Global Market on December 31, 2025, the last trading day of the year 2025, to estimate the value of our common stock upon acceleration. The value of the option

------

vesting acceleration was calculated by multiplying the number of unvested shares underlying stock options subject to vesting acceleration as of December 31, 2025 by the difference between the closing price of our common stock as reported on the Nasdaq Global Market on December 31, 2025 and the exercise price for such unvested stock options.

**Limitation of Liability and Indemnification Agreements** 

Section 145 of the Delaware General Corporation Law, or DGCL, authorizes a corporation to indemnify its directors and officers against liabilities arising out of actions, suits and proceedings to which they are made or threatened to be made a party by reason of the fact that they have served or are currently serving as a director or officer to a corporation. The indemnity may cover expenses (including attorneys' fees) judgments, fines and amounts paid in settlement actually and reasonably incurred by the director or officer in connection with any such action, suit or proceeding. Section 145 permits corporations to pay expenses (including attorneys' fees) incurred by directors and officers in advance of the final disposition of such action, suit or proceeding. In addition, Section 145 provides that a corporation has the power to purchase and maintain insurance on behalf of its directors and officers against any liability asserted against them and incurred by them in their capacity as a director or officer, or arising out of their status as such,

------

whether or not the corporation would have the power to indemnify the director or officer against such liability under Section 145.

We have adopted provisions in our certificate of incorporation and bylaws that limit or eliminate the personal liability of our directors to the fullest extent permitted by the DGCL, as it now exists or may in the future be amended. Consequently, a director will not be personally liable to us or our shareholders for monetary damages or breach of fiduciary duty as a director, except for liability for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•any breach of the director's duty of loyalty to us or our shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•any unlawful payments related to dividends or unlawful stock purchases, redemptions or other distributions; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•any transaction from which the director derived an improper personal benefit.

These limitations of liability do not alter director liability under the federal securities laws and do not affect the availability of equitable remedies such as an injunction or rescission.

In addition, the bylaws provide that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•we will indemnify our directors, officers and, in the discretion of our board of directors, certain employees to the fullest extent permitted by the DGCL, as it now exists or may in the future be amended; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•we will advance reasonable expenses, including attorneys' fees, to our directors and, in the discretion of our board of directors, to our officers and certain employees, in connection with legal proceedings relating to their service for or on behalf of us, subject to limited exceptions.

We have entered into indemnification agreements with each of our directors and our executive officers. These agreements provide that we will indemnify each of our directors, our executive officers and, at times, their affiliates to the fullest extent permitted by Delaware law. We will advance expenses, including attorneys' fees (but excluding judgments, fines and settlement amounts), to each indemnified director, executive officer or affiliate in connection with any proceeding in which indemnification is available; and we will indemnify our directors and officers for any action or proceeding arising out of that person's services as a director or officer brought on behalf of us or in furtherance of our rights. Additionally, certain of our directors or officers may have certain rights to indemnification, advancement of expenses or insurance provided by their affiliates or other third parties, which indemnification relates to and might apply to the same proceedings arising out of such director's or officer's services as a director referenced herein. Nonetheless, we have agreed in the indemnification agreements that our obligations to those same directors or officers are primary and any obligation of such affiliates or other third parties to advance expenses or to provide indemnification for the expenses or liabilities incurred by those directors are secondary.

We also maintain general liability insurance which covers certain liabilities of our directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers, including liabilities under the Securities Act of 1933, as amended, or the Securities Act.

**Compensation Committee Interlocks and Insider Participation** 

Jeffrey Albers, Felix J. Baker and John Maraganore served on our Compensation Committee in 2025. None of our executive officers currently serves, or in the past fiscal year has served, as a member of the board of directors or Compensation Committee, or other committee serving an equivalent function, of any entity that has one or more executive officers who serve as members of our board of directors or our Compensation Committee. None of the members of our Compensation Committee is an officer or employee of our company, and none of the members of our Compensation Committee was an officer or employee of our company in the past fiscal year.

(1) The weighted average exercise price is calculated based solely on outstanding stock options. This weighted-average exercise price does not reflect shares subject to restricted stock units.

(2) Consists of our 2018 Stock Option and Grant Plan, or 2018 Plan, our 2020 Stock Option and Incentive Plan, as amended, or 2020 Plan, and our Amended and Restated 2020 Employee Stock Purchase Plan, or 2020 ESPP. Following August 2020, we did not grant any awards under our 2018 Plan, but all outstanding awards under such plan continue to be governed by their existing terms. The shares of common stock underlying any awards granted under the 2018 Plan or 2020 Plan that are forfeited, canceled, or otherwise terminated (other than by exercise) and the shares of common stock that are withheld upon exercise of a stock option or settlement of such award to cover the exercise price or tax withholding will be added to the shares of common stock available for issuance under the 2020 Plan.

(3) Does not include purchase rights accruing under the 2020 ESPP as of December 31, 2025, because the purchase rights (and, therefore, the number of shares to be purchased) will not be determined until the end of the purchase period on May 31, 2026. Subject to the number of shares remaining in the share reserve, the maximum number of shares purchasable by any participant in the 2020 ESPP plan during the purchase period beginning December 1, 2025 and ending on May 31, 2026 is 373.

(4) Consists of shares available for future issuance under the 2020 ESPP and the 2020 Plan. As of December 31, 2025, 2,303,412 shares of common stock were available for issuance under the 2020 ESPP and 4,182,654 shares of common stock were available for issuance under the 2020 Plan.

(5) The 2020 Plan provides that the number of shares reserved and available for issuance under the plan will automatically increase each January 1, beginning on January 1, 2021, by 4% of the outstanding number of shares of common stock, inclusive of outstanding pre-funded warrants, on the immediately preceding December 31, or such lesser number of shares as determined by our Compensation Committee. The 2020 ESPP provides that the number of shares reserved and available for issuance will automatically increase each January 1, beginning on January 1, 2021, by the least of 438,898 shares of our common stock, 1% of the outstanding number of shares of our common stock on the immediately preceding December 31, or such lesser number of shares as determined by our administrator of the 2020 ESPP. The number in the table does not include the increases from January 1, 2026.

Amounts paid to Dr. Mainolfi, our Founder, President and Chief Executive Officer and a director are presented above in the "Summary Compensation Table."

**Non-Employee Director Compensation Policy** 

Our non-employee director compensation policy is described below. On June 25, 2025, we amended and restated our non-employee director compensation policy, cash retainers and the annual option grant policy for 2025 remained unchanged from 2024. Our non-employee directors are eligible to receive the following cash retainer:

Our non-employee director compensation policy provides that, upon initial election to our board of directors, each non-employee director will be granted an option to purchase shares of our common stock, or the Initial Grant. The number of shares subject to the Initial Grant is periodically reviewed by the Compensation Committee, and on June 25, 2025, our non-employee director compensation policy was revised to decrease the Initial Grant from 32,000 shares to 28,000 shares. The Initial Grant will vest in 36 equal monthly installments over three years from the grant date, subject to continued service as a director through the applicable vesting date. Furthermore, on the date of each annual meeting of shareholders, each non-employee director who continues as a non-employee director, other than a director who has received an Initial Grant in the same calendar year of the annual meeting of shareholders for a particular year, following such meeting will be granted an option to purchase shares of our common stock, or the Annual Grant. The number of shares subject to the Annual Grant is periodically reviewed by the Compensation Committee, and on March 27, 2024, our non-employee director compensation policy was revised to increase the Annual Grant from 12,000 shares to 16,000 shares. The Annual Grant will vest in full on the earlier of (i) the first anniversary of the grant date or (ii) our next annual meeting of shareholders, subject to continued service as a director through the applicable vesting date. Such awards are subject to full accelerated vesting upon the sale of the company.

The grant date fair value of all equity awards and all other cash compensation paid by us to any non-employee director in any calendar year for services as a non-employee director shall not exceed $750,000; provided, however, that such amount shall be $1,000,000 for the calendar year in which the applicable non-employee director is initially elected or appointed to the board of directors.

We will reimburse all reasonable out-of-pocket expenses incurred by non-employee directors in attending meetings of the board of directors and committees thereof.

**CEO Pay Ratio Disclosure** 

Under rules adopted pursuant to the Dodd-Frank Act, we are required to calculate and disclose the total compensation paid to our median paid employee, as well as the ratio of the total compensation paid to the median employee as compared to the total compensation paid to our Chief Executive Officer, or the CEO Pay Ratio. The paragraphs that follow describe our methodology and the resulting CEO Pay Ratio.

------

**Measurement Date** 

We identified the median employee using our employee population on December 1, 2025 (including all employees, whether employed on a full-time, part-time, seasonal or temporary basis).

**Consistently Applied Compensation Measure** 

Under the relevant rules, we are required to identify the median employee by use of a "consistently applied compensation measure", or CACM. We chose a CACM that closely approximates the annual target total direct compensation of our employees. Specifically, we identified the median employee by aggregating, for each employee: (1) annual base pay, (2) annual target cash incentive opportunity, and (3) the grant date fair value for equity awards granted in 2025. In identifying the median employee, we annualized the compensation values of individuals that joined our company during 2025. After applying our CACM methodology, we identified the median employee. Once the median employee was identified, we calculated the median employee's annual target total direct compensation in accordance with the requirements of the Summary Compensation Table.

**Pay Ratio** 

Under rules adopted pursuant to the Dodd-Frank Act, we are required to calculate and disclose the total compensation paid to our median paid employee, as well as the ratio of the total compensation paid to the median employee as compared to the total compensation paid to our Chief Executive Officer. The paragraphs that follow describe our methodology and the resulting CEO Pay Ratio.

In 2025, we identified the median employee by aggregating, for each employee: (1) annual base pay, (2) annual target cash incentive opportunity, and (3) the grant date fair value for equity awards granted in 2025. In identifying the median employee, we annualized the compensation values of individuals that joined our company during 2025. After applying our CACM methodology, we identified the median employee as of December 1, 2025.

Once the median employee was identified, we calculated the median employee's annual target total direct compensation in accordance with the requirements of the Summary Compensation Table.

Our median employee compensation in 2025 as calculated using Summary Compensation Table requirements was $409,607. Our Chief Executive Officer's compensation in 2025 as reported in the Summary Compensation Table was $8,545,609. Therefore, our CEO Pay Ratio for 2025 is approximately 21:1.

This information is being provided for compliance purposes and is a reasonable estimate calculated in a manner consistent with the SEC rules, based on our internal records and the methodology described above. The SEC rules for identifying the median compensated employee allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may use different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios. Neither our Compensation Committee nor our management used the CEO Pay Ratio measure in making compensation decisions.

**Pay Versus Performance** 

The following table reports the compensation for Dr. Mainolfi (our Principal Executive Officer, or PEO) and the average compensation of the other Named Executive Officers (Other NEOs) as reported in the Summary Compensation Table in our proxy statements for the past five fiscal years, as well as their "compensation actually paid" (CAP), as calculated pursuant to recently adopted SEC rules and certain performance measures required by the rules. The grant date fair values included in the Summary Compensation Table (SCT) have been replaced with fair values reflecting the change in value of equity awards during the fiscal year. The calculations do not reflect the actual sale of stock underlying equity awards or the exercise of stock options by the executive. For the year ended December 31, 2025, we did not use any financial performance measures to link company performance to compensation actually paid and, as such, we have omitted the "Company Selected Measure" from the Pay Versus Performance Table and are also omitting the Tabular List of Financial Performance Measures from this Pay versus Performance Disclosure. Nonetheless we have presented information in the Pay Versus Performance table below regarding certain financial performance measures as required by Item 402(v) of Regulation S-K.

(6) The dollar amounts reported represent the amount of net loss reflected in the company's audited financial statements for the applicable fiscal year.

**Financial Performance Measures** 

As described in greater detail in "Compensation Discussion and Analysis," the company's compensation programs are designed to enable us to attract and retain the leadership talent that is necessary to successfully manage our strong earnings growth and return on invested capital objectives, while balancing necessary investment in the businesses in order to achieve attractive, long-term shareholder returns. As required by Item 402(v) of Regulation S-K, the following is a list of performance measures, which in our assessment represents the most important performance measures used by the company to link compensation actually paid to the company's NEOs for 2025:

**Description of the Relationship Between Compensation Actually Paid and Selected Performance Metrics** 

As described above in the section titled "Compensation Discussion and Analysis," our compensation program is designed to attract and retain high-performing talent in our industry, motivate our executive officers to create long-term, enhanced shareholder value, and provide a fair reward for executive effort and stimulate professional and personal growth. The company uses several performance measures to align executive compensation with company performance, not all of which are presented in the Pay versus Performance table above. Moreover, the company calculates compensation to the PEO and other NEOs on a basis different than the amount reported in the Summary Compensation Table and, compensation actually paid, as calculated in accordance with Item 402(v) of Regulation S-K, is not considered by our board of directors or the Compensation Committee in evaluating or determining executive compensation. In accordance with Item 402(v) of Regulation S-K, the company is providing the following descriptions of the relationships between compensation actually paid and the financial performance metrics presented in the Pay versus Performance table.

**Compensation Actually Paid and Net Loss** 

Because we are not a commercial-stage company, we did not have any revenue during the periods presented, other than the recognition of non-cash deferred revenue associated with our collaboration agreements. Consequently, our company has not historically looked to net income (loss) as a performance measure for our executive compensation program. From 2021 through 2022, our net loss increased year over year, while our net loss slightly decreased in 2023 before increasing again in 2024 and 2025. The Compensation Actually Paid to our PEO and Other NEOs does not correlate to the net loss reported year to year.

------

**PEO and Other NEO Compensation Actually Paid and Company Total Shareholder Return ("TSR")** 

Equity awards are the largest component of our executive compensation program, representing no less than 80% of the target total compensation for each of our executives. Therefore, TSR has a significant impact on our CAP, particularly for executives who have been with us for several years and who have multiple years of outstanding equity awards. The impact is more pronounced for our CEO/PEO, given he has historically received equity in the form of stock options only whereas the Other NEOs receive a blend of stock options and restricted stock units. The CEO/PEO also receives a larger magnitude of equity relative to the other NEOs, consistent with market practice. Due to the significant weighting of equity in our total compensation, the decline in our stock price between the end of 2021 and 2022 resulted in negative CAP for our PEO and Other NEOs.

TSR for our peer group is based on the Nasdaq Biotechnology Index (XNBI), which reflects the company's industry sector and is also the peer group used in our Annual Report on Form 10-K. We outperformed our peers during 2021, reflecting the substantial progress towards our stated goals and the achievement of significant milestones including encouraging clinical data for our lead candidate KT-474 and progression of our other clinical and preclinical stage programs. However, due to the decline in our stock price at the end of 2022 and into 2023, our TSR closed lower than our peers. In 2024 and 2025, the achievement of our corporate goals, including significant progress across our clinical and pipeline programs, led to our TSR closing higher than our peers again, and we expect the level of achievement of these goals to meaningfully impact our TSR in 2026 and beyond.

**Policies and Practices Regarding Grants of Equity Awards** 

Our Compensation Committee and board of directors generally make equity grants on regularly scheduled dates, which includes grants in March for executive officers and other employees and following our annual meetings of shareholders in June for non-employee directors. The board of directors or Compensation Committee may change any regularly scheduled grant date if the board of directors or Compensation Committee determines that making grants on such date would not be in the company's best interest. Equity grants may also be made on other dates in connection with new hires, promotions or similar events. During 2025, our Compensation Committee did not take into account any material nonpublic information when determining the timing and terms of equity incentive awards, and we did not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation.

**Indemnification Agreements** 

In connection with our initial public offering in August 2020, the election of new directors, and entrance into employment agreements with certain other executive officers, we entered into new agreements to indemnify our directors and executive officers. These agreements, among other things, require us to indemnify these individuals for certain expenses (including attorneys' fees), judgments, fines and settlement amounts reasonably incurred by such person in any action or proceeding, including any action by or in our right, on account of any services undertaken by such person on behalf of our company or that person's status as a member of our board of directors to the maximum extent allowed under Delaware law.

**Policies for Approval of Related Party Transactions** 

Our board of directors reviews and approves transactions with directors, officers and holders of five percent or more of our voting securities and their affiliates, each a related party. Prior to our initial public offering in August 2020, the material facts as to the related party's relationship or interest in the transaction were disclosed to our board of directors prior to their consideration of such transaction, and the transaction was not considered approved by our board of directors unless a majority of the directors who are not interested in the transaction approved the transaction. Further, when shareholders are entitled to vote on a transaction with a related party, the material facts of the related party's relationship or interest in the transaction were disclosed to the shareholders, who must approve the transaction in good faith.

In connection with our initial public offering in August 2020, we adopted a written related party transactions policy that provides that such transactions must be approved by our Audit Committee. This policy became effective on August 20, 2020. Pursuant to this policy, the Audit Committee has the primary responsibility for reviewing and approving or disapproving "related party transactions," which are transactions between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. For purposes of this policy, a related person will be defined as a director, executive officer, nominee for director, or greater than 5% beneficial owner of our common stock, in each case since the beginning of the most recently completed year, and their immediate family members.

**PRINCIPAL SHAREHOLDERS** 

The following table sets forth information, to the extent known by us or ascertainable from public filings, with respect to the beneficial ownership of our common stock as of March 31, 2026 by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•each person or group of affiliated persons known by us to be the beneficial owner of more than five percent of our capital stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•each of our named executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•each of our directors; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all of our directors and executive officers as a group.

The column entitled "Shares Beneficially Owned" is based on a total of 82,182,101 shares of our common stock outstanding as of March 31, 2026. We have determined beneficial ownership in accordance with the rules of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities as well as any shares of common stock that the person has the right to acquire within 60 days of March 31, 2026 through the exercise of stock options or other rights. These shares are deemed to be outstanding and beneficially owned by the person holding those options for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them.
