TABLE OF CONTENTS

LEGAL MATTERS

Reorganization. Apogee Therapeutics, LLC was formed as a limited liability company under the laws of the State of Delaware in February 2022. Apogee Therapeutics, Inc. was incorporated in June 2023, in connection with our initial public offering (“IPO”) to serve as a holding company that would wholly own the assets of Apogee Therapeutics, LLC. Prior to July 13, 2023, our business was conducted by Apogee Therapeutics, LLC and its subsidiary, Apogee Biologics, Inc. In July 2023, in connection with our IPO, we completed a series of transactions which are referred to, collectively, as the “Reorganization,” and pursuant to which Apogee Therapeutics, Inc., became the parent and holding company that wholly owns the assets of Apogee Therapeutics, LLC, including stock of its subsidiary, Apogee Biologics, Inc. Effective December 31, 2024, Apogee Biologics, Inc. merged with and into Apogee Therapeutics, Inc. with Apogee Therapeutics, Inc. surviving the merger. As used in this Proxy Statement, unless the context otherwise requires, references to “we,” “us,” “our,” the “Company,” “Apogee” and similar references refer: (1) following the consummation of our Reorganization, to Apogee Therapeutics, Inc. and our subsidiary, and (2) prior to the completion of our Reorganization, to Apogee Therapeutics, LLC and its subsidiary.

PROXY STATEMENT

FOR THE 2026 ANNUAL MEETING OF STOCKHOLDERS

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND VOTING

What Is the Purpose of These Proxy Materials?

We are making these proxy materials available to you in connection with the solicitation of proxies by the Board of Directors (the “Board”) of Apogee Therapeutics, Inc. (“we,” “us,” “our” or the “Company”) for use at the 2026 Annual Meeting of Stockholders (the “Annual Meeting”) to be held virtually on June 9, 2026 at 11:00 a.m. Eastern Time, or at any other time following adjournment or postponement thereof.

You are invited to participate in the Annual Meeting and to vote on the proposals described in this proxy statement (the “Proxy Statement”). The proxy materials are first being made available to our stockholders on or about April 24, 2026.

Why Did I Receive a Notice of Internet Availability?

Pursuant to SEC rules, we are furnishing the proxy materials to our stockholders primarily via the Internet instead of mailing printed copies. This process allows us to expedite our stockholders’ receipt of proxy materials, lower the costs of printing and mailing the proxy materials and reduce the environmental impact of our Annual Meeting. If you received a Notice of Internet Availability of Proxy Materials (the “Notice”), you will not receive a printed copy of the proxy materials unless you request one. The Notice provides instructions on how to access the proxy materials for the Annual Meeting via the Internet, how to request a printed set of proxy materials and how to vote your shares.

Why Are We Holding a Virtual Annual Meeting?

We have adopted a virtual meeting format for the Annual Meeting to provide a consistent experience to all stockholders regardless of geographic location. We believe this expands stockholder access, improves communications and lowers our costs while reducing the environmental impact of the meeting. In structuring our virtual Annual Meeting, our goal is to enhance rather than constrain stockholder participation in the meeting, and we have designed the meeting to provide stockholders with the same rights and opportunities to participate as they would have at an in-person meeting.

Who Can Vote?

Only stockholders of record at the close of business on April 15, 2026 (the “Record Date”) are entitled to notice of the Annual Meeting and to vote on the proposals described in this Proxy Statement. At the close of business on the Record Date, 61,853,254 shares of our voting common stock were issued and outstanding. Shares of our non-voting common stock generally do not have voting rights and holders of our non-voting common stock are therefore not entitled to vote at the Annual Meeting. Unless otherwise noted, all references to our “common stock” herein refers to our voting common stock.

Why Does the Company have Non-Voting Common Stock?

We created a class of non-voting common stock solely to facilitate certain of our pre-IPO holders of Series A preferred units and Series B preferred units of Apogee Therapeutics, LLC being able to beneficially own our common stock without exceeding certain beneficial ownership thresholds. Specifically, as part of the Reorganization, pursuant to a contribution and exchange agreement, effective July 13, 2023, holders of Series A preferred units and Series B preferred units of Apogee Therapeutics, LLC contributed their Series A preferred units and Series B preferred stock units to Apogee Therapeutics, Inc. in exchange for shares of non-voting common stock of Apogee Therapeutics, Inc. Holders of our non-voting common stock shall have the right to convert each share of our non-voting common stock into one share of common stock at such holder’s election, provided that as a result of such conversion, such holder, together with its affiliates and any members of a Schedule 13(d) group with such holder, would not beneficially own in excess of 9.99% of our common stock immediately prior to and following such conversion (the “Beneficial Ownership Limitation”), unless otherwise as expressly provided for in our amended and restated certificate of incorporation (“Certificate of Incorporation”). However, the Beneficial Ownership Limitation may be increased or decreased to any other percentage (not to exceed 19.99%) designated by such holder of non-voting common stock upon 61 days’ notice to us.

What Is the Difference between Holding Shares as a Registered Stockholder and as a Beneficial Owner?

Registered Stockholder: Shares Registered in Your Name

If your shares of common stock are registered directly in your name with our transfer agent, Computershare Trust Company, N.A., you are considered to be, with respect to those shares of common stock, the registered stockholder, and these proxy materials are being sent directly to you by us.

Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary or Custodian

If your shares of common stock are held by a broker, fiduciary or custodian, you are considered the beneficial owner of shares of common stock held in “street name,” and these proxy materials are being forwarded to you from that broker, fiduciary or custodian.

How Can I Participate in the Virtual Annual Meeting?

Stockholders of record as of the close of business on the Record Date are entitled to participate in and vote at the Annual Meeting. To participate in the Annual Meeting, including to vote and ask questions, stockholders of record should go to the meeting website at www.virtualshareholdermeeting.com/APGE2026, enter the 16-digit control number found on your proxy card or Notice, and follow the instructions on the website. If your shares are held in street name and your voting instruction form or Notice indicates that you may vote those shares through www.proxyvote.com, then you may access, participate in and vote at the Annual Meeting with the 16-digit access code indicated on that voting instruction form or Notice. Otherwise, stockholders who hold their shares in street name should contact their bank, broker or other nominee (preferably at least five days before the Annual Meeting) and obtain a “legal proxy” in order to be able to attend, participate in or vote at the Annual Meeting.

We will endeavor to answer as many stockholder-submitted questions as time permits that comply with the Annual Meeting rules of conduct. 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.

The meeting webcast will begin promptly at 11:00 a.m. Eastern Time. Online check-in will begin approximately 15 minutes before then, and we encourage you to allow ample time for check-in procedures. If you experience technical difficulties during the check-in process or during the meeting, please call the number listed on the meeting website for technical support. Additional information regarding the rules and procedures for participating in the Annual Meeting will be set forth in our meeting rules of conduct, which stockholders can view during the meeting at the meeting website.

What Am I Voting on?

The proposals to be voted on at the Annual Meeting are as follows:

How Does the Board Recommend That I Vote?

The Board recommends that you vote your shares “FOR” each director nominee in Proposal 1, “FOR” Proposal 2 and “FOR” for Proposal 3.

What If Another Matter Is Properly Brought before the Annual Meeting?

As of the date of filing this Proxy Statement, the Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, it is the intention of the persons named as proxies in the proxy card to vote on such matters in accordance with their best judgment.

How Many Votes Do I Have?

Each share of voting common stock is entitled to one vote on each proposal to be voted on at the Annual Meeting.

What Does It Mean If I Receive More Than One Set of Proxy Materials?

If you receive more than one set of proxy materials, your shares may be registered in more than one name or held in different accounts. Please cast your vote with respect to each set of proxy materials that you receive to ensure that all of your shares are voted.

How Do I Vote?

Even if you plan to attend the Annual Meeting, we recommend that you also submit your vote as early as possible in advance so that your vote will be counted if you later decide not to, or are unable to, virtually attend the Annual Meeting.

Registered Stockholder: Shares Registered in Your Name

If you are the registered stockholder, you may vote your shares online during the virtual Annual Meeting (see “How Can I Participate in the Virtual Annual Meeting?” above) or by proxy in advance of the Annual Meeting by Internet (at www.proxyvote.com) or, if you requested paper copies of the proxy materials, by completing and mailing a proxy card or by telephone (at 800-690-6903).

Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary or Custodian

If you are the beneficial owner, you may vote your shares online during the virtual Annual Meeting (see “How Can I Participate in the Virtual Annual Meeting?” above) or you may direct your broker, fiduciary or custodian how to vote in advance of the Annual Meeting by following the instructions they provide.

What Happens If I Do Not Vote?

Registered Stockholder: Shares Registered in Your Name

If you are the registered stockholder and do not vote in one of the ways described above, your shares will not be voted at the Annual Meeting and will not be counted toward the quorum requirement.

Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary or Custodian

If you are the beneficial owner and do not direct your broker, fiduciary or custodian on how to vote your shares, your broker, fiduciary or custodian will only be able to vote your shares with respect to proposals considered to be “routine.” Your broker, fiduciary or custodian is not entitled to vote your shares with respect to “non-routine” proposals, which we refer to as a “broker non-vote.” Whether a proposal is considered routine or non-routine is subject to stock exchange rules and final determination by the stock exchange. Even with respect to routine matters, some brokers are choosing not to exercise discretionary voting authority. As a result, we urge you to direct your broker, fiduciary or custodian on how to vote your shares on all proposals to ensure that your vote is counted.

What If I Sign and Return a Proxy Card or Otherwise Vote but Do Not Indicate Specific Choices?

Registered Stockholder: Shares Registered in Your Name

The shares represented by each signed and returned proxy will be voted at the Annual Meeting by the persons named as proxies in the proxy card in accordance with the instructions indicated on the proxy card. However, if you are the registered stockholder and sign and return your proxy card without giving specific instructions, the persons named as proxies in the proxy card will vote your shares in accordance with the recommendations of the Board. Your shares will be counted toward the quorum requirement.

Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary or Custodian

If you are the beneficial owner and do not direct your broker, fiduciary or custodian on how to vote your shares, your broker, fiduciary or custodian will only be able to vote your shares with respect to proposals considered to be “routine.” Your broker, fiduciary or custodian is not entitled to vote your shares with respect to “non-routine” proposals, resulting in a broker non-vote with respect to such proposals.

Can I Change My Vote after I Submit My Proxy?

Registered Stockholder: Shares Registered in Your Name

If you are the registered stockholder, you may revoke your proxy at any time before the final vote at the Annual Meeting in any one of the following ways:

Your last submitted vote is the one that will be counted.

Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary or Custodian

If you are the beneficial owner, you must follow the instructions you receive from your broker, fiduciary or custodian with respect to changing your vote.

What Is the Quorum Requirement?

The holders of a majority of the shares of common stock outstanding and entitled to vote at the Annual Meeting, either virtually or represented by proxy, must be present at the Annual Meeting to constitute a quorum. A quorum is required to transact business at the Annual Meeting.

Your shares will be counted toward the quorum only if you submit a valid proxy (or a valid proxy is submitted on your behalf by your broker, fiduciary or custodian) or if you attend the Annual Meeting virtually and vote. Abstentions and broker non-votes, if any, will be counted toward the quorum requirement. If there is no quorum, the chair of the Annual Meeting or the holders of a majority of shares of common stock present at the Annual Meeting, either virtually or represented by proxy, may adjourn the Annual Meeting to another time or date.

How Many Votes Are Required to Approve Each Proposal and How Are Votes Counted?

Votes will be counted by Broadridge Financial Solutions, the Inspector of Elections appointed for the Annual Meeting.

Proposal 1: Election of Directors

A nominee will be elected as a director at the Annual Meeting if the nominee receives a plurality of the votes cast “FOR” his or her election. “Plurality” means that the individuals who receive the highest number of votes cast “FOR” are elected as directors. Broker non-votes, if any, and votes that are withheld will not be counted as votes cast on the matter and will have no effect on the outcome of the election. Stockholders do not have cumulative voting rights for the election of directors.

Proposal 2: Ratification of Independent Auditor Appointment

The affirmative vote of the holders of at least a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote on the matter is required to approve this proposal. Abstentions will have the same effect as a vote “AGAINST” the matter. Broker non-votes, if any, will have no effect on the outcome of the matter.

Proposal 3: Advisory Vote on our NEOs’ Compensation

The advisory vote on the compensation of our NEOs requires the affirmative vote of the holders of at least a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote on the matter. Abstentions will have the same effect as a vote “AGAINST” the matter. Broker non-votes, if any, will have no effect on the outcome of the matter.

Who Is Paying for This Proxy Solicitation?

We will pay the costs associated with the solicitation of proxies, including the preparation, assembly, printing and mailing of the proxy materials. We may also reimburse brokers, fiduciaries or custodians for the cost of forwarding proxy materials to beneficial owners of shares of common stock held in “street name.”

Our employees, officers and directors may solicit proxies in person or via telephone or the Internet. We will not pay additional compensation for any of these services.

How Can I Find out the Voting Results?

We expect to announce preliminary voting results at the Annual Meeting. Final voting results will be published in a Current Report on Form 8-K to be filed with the SEC within four business days after the Annual Meeting.

PROPOSAL 1: ELECTION OF DIRECTORS

In accordance with our Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) and Amended and Restated Bylaws (the “Bylaws”), the Board has fixed the number of directors constituting the Board at seven, effective as of May 11, 2026. At the Annual Meeting, the stockholders will vote to elect the three Class III director nominees named in this Proxy Statement to serve until the 2029 Annual Meeting of Stockholders and until their successors are duly elected and qualified or until their earlier resignation or removal. Our Board has nominated Mark C. McKenna, Jennifer Fox and William (BJ) Jones, Jr. for election to our Board. Mr. McKenna was appointed to our Board in August 2023, and Ms. Fox and Mr. Jones have served on our Board since prior to our IPO in July 2023. Mr. McKenna was recommended to the Nominating and Corporate Governance Committee (the “Nominating Committee”) by a third-party search firm.

Our director nominees have indicated that they are willing and able to serve as directors. However, if any of them becomes unable or, for good cause, unwilling to serve, proxies may be voted for the election of such other person as shall be designated by our Board, or the Board may decrease the size of the Board.

Information Regarding Director Nominees and Continuing Directors

Our Board is divided into three classes, with members of each class holding office for staggered three-year terms. On April 21, 2026, Class I directors, Andrew Gottesdiener, M.D. and Peter Harwin, each notified the Board of his intention to resign from the Board effective May 11, 2026. The resignations of Dr. Gottesdiener and Mr. Harwin are not the result of any disagreement with the Company on any matter relating to the Company’s operations, policies or practices. The size of the Board will be reduced from nine directors to seven directors effective May 11, 2026.

There are currently three Class III directors, who are up for election at this meeting for a term expiring at the 2029 Annual Meeting of Stockholders; effective as of May 11, 2026, one Class I director, whose term expires at the 2027 Annual Meeting of Stockholders; and currently three Class II directors, whose terms expire at the 2028 Annual Meeting of Stockholders.

Biographical and other information regarding our director nominees and directors continuing in office, including the primary skills and experiences considered by our Nominating Committee in determining to recommend them as nominees, is set forth below. The Board committee composition set forth below reflects updated committee membership effective as of May 11, 2026.

Board Recommendation

The Board recommends a vote “FOR” the election of each of the Class III director nominees set forth above.

PROPOSAL 2: RATIFICATION OF INDEPENDENT AUDITOR APPOINTMENT

Our Audit Committee has appointed EY as the Company’s independent registered public accounting firm for the year ending December 31, 2026. In this Proposal 2, we are asking stockholders to vote to ratify this appointment. Representatives of EY are expected to be present at the Annual Meeting. They will have the opportunity to make a statement, if they desire to do so, and are expected to be available to respond to appropriate questions from stockholders.

Stockholder ratification of the appointment of EY as the Company’s independent auditor is not required by law or our Bylaws. However, we are seeking stockholder ratification as a matter of good corporate governance. If our stockholders fail to ratify the appointment, the committee will reconsider its appointment. Even if the appointment is ratified, the committee, in its discretion, may direct the appointment of a different independent auditor at any time during the year if it determines that such a change would be in the best interests of the Company and our stockholders.

EY has served as our independent auditor since 2023. The following table summarizes the audit fees billed and expected to be billed by EY for the indicated fiscal years and the fees billed by EY for all other services rendered during the indicated fiscal years. All services associated with such fees and provided in 2025 were pre-approved by our Audit Committee in accordance with the “Pre-Approval Policies and Procedures” described below.

Pre-Approval Policies and Procedures

Our Audit Committee has adopted procedures requiring the pre-approval of all audit and non-audit services performed by our independent auditor in order to assure that these services do not impair the auditor’s independence. These procedures generally approve the performance of specific services subject to a cost limit for all such services. This general approval is reviewed, and if necessary modified, at least annually. Management must obtain the specific prior approval of the committee for each engagement of our auditor to perform other audit-related or non-audit services. The committee does not delegate its responsibility to pre-approve services performed by our auditor to any member of management. The committee has delegated authority to the committee chair to pre-approve audit and non-audit services to be provided to us by our auditor provided that the fees for such services do not exceed $200,000. Any pre-approval of services by the committee chair pursuant to this delegated authority must be reported to the committee at its next regularly scheduled meeting.

Report of the Audit Committee

The Audit Committee has reviewed and discussed the audited financial statements for the year ended December 31, 2025 with the Company’s management and with EY, the Company’s independent registered public accounting firm. The Audit Committee has discussed with EY the matters required to be discussed by the applicable standards of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The Audit Committee has also received the written disclosures and the letter from EY pursuant to applicable PCAOB requirements regarding its communications with the Audit Committee concerning independence, and the Audit Committee has discussed with EY its independence. Based on the foregoing, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 for filing with the SEC.

This report is provided by the following directors, who serve on the Audit Committee:

Jennifer Fox (Chair)

Andrew Gottesdiener, M.D.

Peter Harwin

Board Recommendation

The Board recommends a vote “FOR” this proposal.

PROPOSAL 3: ADVISORY VOTE ON THE EXECUTIVE COMPENSATION OF

OUR NEOS

In accordance with the rules of the SEC and pursuant to the Dodd-Frank Act, we are asking stockholders to cast a non-binding, advisory vote on the compensation of our NEOs (as disclosed under the section titled “Executive Compensation,” including the compensation tables included therein and the accompanying narrative disclosure) (the “Say-on-Pay Vote”).

As an advisory vote, this proposal is not binding. However, our Board and Compensation Committee, which is responsible for designing and administering our executive compensation program, value the opinions expressed by stockholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for our NEOs.

We are required to hold a Say-on-Pay Vote at least once every three years, and we have determined to hold this vote every year. Unless the Board modifies its policy on the frequency of holding Say-on-Pay Votes, the next such vote is expected to occur in 2027.

The vote on this resolution is not intended to address any specific element of compensation but rather relates to the overall compensation of our NEOs, as described in this Proxy Statement. As discussed under the section titled “Compensation Discussion and Analysis,” our Board believes that its compensation philosophy and decisions support our key business objectives of creating value for, and promoting the interests of, our stockholders. Compensation of our NEOs is designed to enable us to attract and retain talented and experienced executives to lead us successfully in a competitive environment.

Board Recommendation

The Board recommends a vote “FOR” the compensation of our NEOs.

CORPORATE GOVERNANCE

Our business affairs are managed under the direction of our Board. Our Board has adopted the Principles of Corporate Governance (the “Corporate Governance Guidelines”) as a framework for the governance of the Company, which is posted on our website located at https://investors.apogeetherapeutics.com under “Corporate Governance.”

Our Governance Structure and Philosophy

Our governance practices reflect the environment in which we operate and are designed to support our mission to reshape the current standard of care for inflammatory and immune diseases. We are a clinical stage biotechnology company in an evolving industry, with a focus on developing our candidate pipeline through both business development and internal research efforts, and, like other companies in the biotechnology industry, face extreme stock price and volume fluctuations that are often unrelated or disproportionate to our operating performance. With these business environment considerations in mind, the Board believes our current governance structure enables the management team to act with deliberation and to focus on delivering long-term value to stockholders and protect minority investors from the interests of potentially short-sighted investors who may seek to act opportunistically and not in the best interests of the Company or stockholders generally. This structure includes the following elements:

Recognizing that the Company’s operating environment continues to evolve and that governance practices should not be static as a matter of course, the Board annually evaluates our governance structure to confirm it remains in the best interests of the Company and stockholders and values input from our stockholders on this topic.

Board Composition

Director Nomination Process

The Nominating Committee is responsible for, among other things, engaging in succession planning for directors and identifying qualified individuals to become members of the Board to oversee management’s execution of the Company’s strategy and safeguard the long-term interests of stockholders. In this regard, the committee is charged with developing and recommending Board membership criteria to the Board for approval, evaluating the composition of the Board annually to assess the skills and experience that are currently represented on the Board and to assess the criteria that may be needed in the future, and identifying and reviewing the qualifications of and recommending potential director candidates.

In identifying potential candidates for Board membership, the Nominating Committee considers recommendations from directors, stockholders, management and others, including, from time to time, third-party search firms to assist it in locating qualified candidates. Once potential director candidates are identified, the committee, with the assistance of management, undertakes a vetting process that considers each candidate’s background, independence and fit with the Board’s priorities. As part of this vetting process, the committee, as well as other members of the Board and our CEO, may conduct interviews with the candidates. If the committee determines that a potential candidate meets the needs of the Board and has the desired qualifications, it recommends the candidate to the full Board for appointment or nomination and to the stockholders for election at the annual meeting.

Criteria for Board Membership

In assessing potential candidates for Board membership and in assessing Board composition, the Nominating Committee considers a wide range of factors, including directors’ experience, knowledge, understanding of our business environment and specific skills they may possess that are helpful to the Company (including leadership experience, financial expertise and industry knowledge). The committee generally seeks to balance the experiences, skills and characteristics represented on the Board and does not assign specific weight to any of these factors. In addition, the Nominating Committee generally believes it is important for all Board members to possess the highest personal and professional ethics, integrity and values, an inquisitive and objective perspective, a sense for priorities and balance, the ability and willingness to devote sufficient time and attention to Board matters, and a willingness to represent the long-term interests of all our stockholders.

Board Diversity

In addition to the factors discussed above, the Board and the Nominating Committee actively seek to achieve a diversity of perspectives, skills and occupational and personal backgrounds on the Board. The Nominating Committee considers a potential director candidate’s ability to contribute to the diversity of personal backgrounds on the Board, including with respect to gender, race, ethnic and national background, geography, age and sexual orientation. As part of the search process for new directors, the Nominating Committee endeavors to include, and instructs any search firm it engages to endeavor to include women and minority candidates in the broader pool of candidates from which the Committee considers director candidates, with the ultimate selection of nominees determined based on merit.

The Nominating Committee assesses its effectiveness in balancing these considerations in connection with its annual evaluation of the composition of the Board. In this regard, our Board of seven directors, as of May 11, 2026, will include two directors (29%) who self-identify as female and three directors (43%) who self-identify as racially/ethnically diverse.

Stockholder Recommendations for Directors

It is the Nominating Committee’s policy to consider written recommendations from stockholders for director candidates. The committee considers candidates recommended by our stockholders in the same manner as a candidate recommended by other sources. Any such recommendations should be submitted to the committee as described under “Stockholder Communications” and should include the same information required under our Bylaws for nominating a director, as described under “Stockholder Proposals and Director Nominations for Next Year’s Annual Meeting.”

Director Time Commitments

While Board members benefit from service on the boards of other companies and such service is encouraged, pursuant to the Corporate Governance Guidelines, directors are expected to limit the number of other boards on which they serve so as not to interfere with their service as a director of the Company. As part of the annual director nomination process, the Nominating Committee considers directors’ adherence to these expectations.

Board Leadership Structure

Currently, the roles of Chair of the Board and the CEO are separate, and the Chair is an independent director - Mr. McKenna serves as our independent Chair of the Board while Dr. Henderson serves as our CEO. The Board believes that this structure is appropriate for the Company as the independent Chair’s leadership of the Board and oversight of corporate governance matters enables our CEO to focus on leading the Company’s business and developing our drug candidate pipeline.

We do not have a policy regarding whether the roles of the Chair and the CEO should be separate or combined, and our Board believes that we should maintain our flexibility to select the Chair and CEO and determine the appropriate leadership structure, from time to time, based on criteria that are in our best interests and the best interests of our stockholders. Our Board periodically reviews its leadership structure to evaluate whether the structure remains appropriate for the Company. At any time when the Chair is not independent or there is not a Chair, the independent directors of the Board will designate an independent director to serve as lead independent director for a period of at least one year.

The independent directors have the opportunity to meet in executive sessions without management present at every regular Board meeting. The purpose of these executive sessions is to encourage and enhance communication among the independent directors.

The Board believes that its programs for overseeing risk, as described under “Board Risk Oversight,” would be effective under a variety of leadership frameworks. Accordingly, the Board’s risk oversight function did not significantly impact its selection of the current leadership structure.

Director Independence

Nasdaq listing rules require a majority of a listed company’s board of directors to be comprised of independent directors who, in the opinion of the board of directors, do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Subject to specified exceptions, each member of a listed company’s audit, compensation and nominating committees must be independent, and audit and compensation committee members must satisfy additional independence criteria under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Our Board undertook a review of its composition and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, our Board has determined that Lisa Bollinger, M.D., Jennifer Fox, Andrew Gottesdiener, M.D., Peter Harwin, William (BJ) Jones, Jr., Tomas Kiselak, Mark C. McKenna and Nimish Shah qualify as “independent directors” as defined by the Nasdaq listing rules. Michael Henderson, M.D., is not an independent director because he is our CEO. In making such determinations, our Board considered the relationships that each such non-employee director has with our Company and all other facts and circumstances our Board deemed relevant in determining independence, including any business, consulting or employment relationships with our significant investors, and the transactions described under “Certain Relationships and Transactions” in this Proxy Statement. Our Board also determined that each of the directors currently serving on the Audit Committee and the Compensation Committee satisfy the additional independence criteria applicable to directors on such committees under Nasdaq listing rules and the rules and regulations established by the SEC.

Board Committees

Our Board has a separately designated Audit Committee, Compensation Committee and Nominating Committee, each of which has the composition and responsibilities described below. Members serve on these committees until their resignation or until otherwise determined by our Board. Each of these committees is empowered to retain outside advisors as it deems appropriate, regularly reports its activities to the full Board and has a written charter, which is posted on our website located at https://investors.apogeetherapeutics.com under “Corporate Governance.” The following table provides membership information for each of the Board committees as of the date of this Proxy Statement.

Audit Committee. The primary responsibilities of our Audit Committee are to oversee the accounting and financial reporting processes of the Company, including the audits of the Company’s financial statements, the integrity of the financial statements and the annual review of the performance, qualifications and independence of the outside auditor. This includes reviewing the financial information provided to stockholders and others and the adequacy and effectiveness of the Company’s internal controls. The committee also makes recommendations to the Board as to whether financial statements should be included in the Company’s Annual Report on Form 10-K.

Ms. Fox qualifies as an “audit committee financial expert,” as that term is defined in the rules and regulations established by the SEC, and all members of the Audit Committee are “financially literate” under Nasdaq listing rules.

Compensation Committee. The primary responsibilities of our Compensation Committee are to periodically review and approve the compensation and other benefits for our senior officers and directors. This includes reviewing and approving corporate goals and objectives relevant to the compensation of our CEO, evaluating the performance of our CEO in light of the goals and objectives and setting or recommending to the Board the CEO’s compensation based on the committee’s evaluation. The committee also oversees the evaluation of other senior officers and sets or recommends to the Board the compensation of such senior officers based upon the recommendation of the CEO. The committee also administers and makes recommendations to the Board regarding equity incentive plans that are subject to the Board’s approval and approves the grant of equity awards under the plans.

The Compensation Committee may delegate its duties and responsibilities to one or more subcommittees. The committee may also delegate authority to review and approve the compensation of our employees to certain of our executive officers. Even where the committee does not delegate authority, our executive officers will typically make recommendations to the committee regarding compensation to be paid to our employees and the size of equity awards under our equity incentive plans but will not be present during voting or deliberations on their own compensation. The committee has the authority to engage outside advisors, such as compensation consultants, to assist it in carrying out its responsibilities. The committee has engaged Alpine Rewards, LLC (“Alpine”) since 2023 to provide advice regarding the amount and form of executive and director compensation. The committee assessed Alpine’s independence and has determined that (1) Alpine satisfies applicable independence criteria, and (2) Alpine’s work with the Company does not raise any conflicts of interest, in each case under applicable Nasdaq listing rules and the rules and regulations established by the SEC.

Nominating Committee. The primary responsibilities of our Nominating Committee are to identify individuals qualified to become members of the Board, recommend director candidates to the Board, including for election or reelection to the Board at each annual stockholders’ meeting, and perform a leadership role in shaping the Company’s corporate governance. In addition, the committee is responsible for developing and recommending to the Board criteria for identifying and evaluating qualified director candidates and developing and recommending to the Board a set of corporate governance principles. The committee is also responsible for making recommendations to the Board concerning the size, structure, composition and functioning of the Board and its committees, engaging in succession planning for the Board and key leadership roles on the Board and its committees and overseeing succession planning for positions held by executive officers and other critical leadership roles.

Board Risk Oversight

We believe that risk management is an important part of establishing and executing on the Company’s business strategy. Our Board, as a whole and at the committee level, focuses its oversight on the most significant risks facing the Company and on the Company’s processes to identify, prioritize, assess, manage and mitigate those risks. The committees oversee specific risks within their purview, as follows:

Our Board and its committees receive regular reports from members of the Company’s senior management on areas of material risk to the Company, including strategic, operational, financial, legal and regulatory risks. While our Board has an oversight role, management is principally tasked with direct responsibility for assessing and managing risks, including implementing processes and controls to mitigate their effects on the Company.

Other Corporate Governance Practices and Policies

Director Attendance

The Board met six times during the year ended December 31, 2025. During 2025, each member of the Board attended at least 75% of the aggregate number of meetings of the Board and the committees on which he or she served during the period in which he or she was on the Board or committee.

Directors are encouraged to attend the annual meeting of stockholders. All of our directors attended the 2025 annual meeting of stockholders.

Stockholder Communications

Stockholders and other interested parties may communicate with our Board or a particular director by sending a letter addressed to the Board or a particular director to our Corporate Secretary at the address set forth on the first page of this Proxy Statement. These communications will be compiled and reviewed by our Corporate Secretary, who will determine whether the communication is appropriate for presentation to the Board or the particular director. The purpose of this screening is to allow the Board to avoid having to consider irrelevant or inappropriate communications (such as advertisements, solicitations and hostile communications).

To enable the Company to speak with a single voice, as a general matter, senior management serves as the primary spokesperson for the Company and is responsible for communicating with various constituencies, including stockholders, on behalf of the Company. Directors may participate in discussions with stockholders and other constituencies on issues where Board-level involvement is appropriate. In addition, the Board oversees the Company’s stockholder engagement efforts.

Code of Business Conduct and Ethics

Our Board has adopted a Code of Business Conduct and Ethics (“the Code of Conduct”) that establishes the standards of ethical conduct applicable to all our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. The full text of our Code of Conduct is posted on our website at https://investors.apogeetherapeutics.com/corporate-governance/governance-overview. It addresses, among other matters, compliance with laws and policies, conflicts of interest, corporate opportunities, regulatory reporting, external communications, confidentiality requirements, insider trading, proper use of assets and how to report compliance concerns. We intend to disclose future amendments to certain provisions of the Code of Conduct and waivers of the Code of Conduct granted to executive officers and directors on the website within four business days following the date of the amendment or waiver. The Audit Committee is responsible for applying and interpreting our Code of Conduct in situations where questions are presented to it.

Insider Trading Policy and Anti-Hedging Policy

We have adopted insider trading policies and procedures governing the purchase, sale and other transactions in Company securities by our directors, officers and employees, and other covered persons, as well as the Company itself, that we believe are reasonably designed to promote compliance with insider trading laws, rules and regulations, and Nasdaq listing rules, as applicable. As part of these policies and procedures, we prohibit our directors, officers, employees and consultants from engaging in (a) short sales; (b) transactions involving publicly traded options or other derivatives, such as trading in puts or calls with respect to Company securities; and (c) hedging or monetization transactions.

Director Compensation

The following table presents all of the compensation awarded to, earned by, or paid to our non-employee directors during the year ended December 31, 2025. We have reimbursed and will continue to reimburse all of our non-employee directors for their reasonable out-of-pocket expenses incurred in attending Board and committee meetings. Dr. Henderson, our CEO, does not receive any additional compensation for his service on the Board. The compensation received by Dr. Henderson for his service as our CEO is presented in the 2025 Summary Compensation Table below.

Director Compensation Policy

Our Board approved our amended director compensation policy for our non-employee directors which went into effect in February 2024 and which consisted of the following:

In March 2025, the Board approved, upon the recommendation of the Compensation Committee, an amended and restated director compensation policy, which became effective as of the date of the 2025 Annual Meeting of Stockholders and which consists of the following:

EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION & ANALYSIS

In this Compensation Discussion and Analysis (“CD&A”) we provide an overview of our compensation philosophy and each element of our executive compensation program with regard to the compensation awarded to, earned by, or paid to our NEOs during our fiscal year ended December 31, 2025.

For the fiscal year ended December 31, 2025, our NEOs were:

Our Compensation Committee believes that executive compensation should be directly linked to short-term and long-term performance. The following compensation features are designed to align our NEOs’ interests with stockholder interests and market best practices:

Compensation Components:

*Equity awards based upon grant date value.

Responsible Executive Compensation Policies and Practices

The following table summarizes our executive compensation policies and practices, including responsible policies and practices we have implemented and the policies and practices we have avoided to better serve our stockholders’ long-term interests.

Consideration of Stockholder Advisory Vote on Executive Compensation

At the 2025 Annual Meeting of Stockholders, consistent with the recommendation of our Board, our stockholders voted to hold non-binding, advisory votes on the compensation of our NEOs (each, a “Say-on-Pay Vote”) every year. Beginning at our 2026 Annual Meeting of Stockholders, and each year thereafter until our next vote on the frequency of Say-on-Pay Votes, which will occur at the 2031 Annual Meeting of Stockholders, our stockholders will be provided the opportunity to cast a Say-on-Pay Vote. Because we value the opinions of our stockholders, the Board and the Compensation Committee will consider the outcome of the Say-on-Pay Vote, as well as any feedback received throughout the year, when making compensation decisions for our NEOs and our executive compensation program in the future.

Compensation Philosophy and Objectives

Our current executive compensation program is intended to align executive compensation with our business objectives and to enable us to attract, retain and reward executive officers who contribute to our long-term success. In furtherance of these goals, the Compensation Committee adheres to the following guidelines when making determinations regarding compensation:

The compensation paid or awarded to our executive officers is generally based on a qualitative assessment of each individual’s performance compared against the business objectives established for the fiscal year as well as market peer group data and our historical compensation practices. In the case of new hire executive officers, their compensation is primarily determined based on the negotiations of the parties, as well as our historical compensation practices and market peer group data. For 2025, 2024, and 2023, the material elements of our executive compensation program were base salary, annual cash bonus awards and long-term equity incentives in the form of incentive units prior to the IPO and stock options following the IPO. The Compensation Committee believes that cash compensation in the form of base salary and an annual bonus opportunity provides our executive officers with short-term rewards for success in achieving annual goals and objectives, and that long-term compensation through the award of stock options aligns the objectives of management with those of our stockholders with respect to long-term performance and success of the Company.

In setting compensation levels for our executive officers, the Compensation Committee considers a variety of factors, including peer group survey data, experience, tenure, role, responsibilities, performance, the relative importance of the executive’s role within the organization and competitive market practices. Compensation paid to our NEOs is delivered primarily through at-risk pay, based on both short-term and long-term incentives.

In addition to our compensation elements, the following compensation program features are designed to align our executive officers’ interests with stockholder interests and market best practices.

Process for Setting Executive Compensation

Our Compensation Committee reviews compensation practices and philosophy annually for all employees, including our executives. In setting executive officer base salaries and bonuses and granting executive officer equity incentive awards, they 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 executive officers to achieve short-and long-term results that are in the best interests of our stockholders and our desire to incentivize a long-term commitment to our Company. While we do not establish compensation levels based solely on benchmarking, pay practices at other companies are an important factor that the Compensation Committee considers in assessing the reasonableness of compensation and ensuring that our compensation practices are competitive in the marketplace.

Our Compensation Committee is responsible for approving all executive compensation matters, and in the case of our CEO, makes recommendations to the Board for approval, as appropriate. Our Compensation Committee typically reviews and discusses management’s proposed compensation with the CEO for all NEOs other than the CEO. Based on those discussions and its discretion, taking into account the factors noted above, the Compensation Committee then determines the compensation for each NEO, and in the case of the CEO, makes recommendations to the Board for approval, as appropriate. While the CEO discusses his recommendations for the other NEOs with the Compensation Committee, he does not participate in the deliberations concerning, or the determination of, his own compensation. Since 2023, our Compensation Committee has engaged Alpine Rewards (“Alpine”) as its independent executive compensation consultant and the Board and the Compensation Committee considered Alpine’s input on certain compensation matters as they deemed appropriate. Pursuant to the factors set forth in Item 407 of Regulation S-K of the Exchange Act, the Compensation Committee has reviewed the independence of Alpine and conducted a conflicts of interest assessment (taking into consideration factors specified in the Nasdaq listing standards) and has concluded that Alpine is independent and its work for the Compensation Committee has not raised any conflicts of interest. No other consulting services were provided by Alpine or its affiliates to the Company in 2025.

Peer Group and the Use of Market Data

While we do not establish compensation levels based solely on benchmarking, pay practices at other companies are an important factor that the Compensation Committee considers in assessing the reasonableness of compensation and ensuring that our compensation practices are competitive in the marketplace. The Compensation Committee reviews all market percentiles of relevant market data as one frame of reference in making its executive compensation decisions.

In order to evaluate the level of compensation for our NEOs for 2025, our Compensation Committee, using information provided by Alpine, established a peer group of publicly traded companies in the biopharmaceutical space (“Peer Group”) based on a balance of the following criteria:

Key Elements of Compensation

Base Salary

Each NEO’s base salary is a fixed component of annual compensation for performing specific duties and functions, and has been established by our Board taking into account each individual’s experience, skills, knowledge and responsibilities, as well as market peer group data. Base salaries for our NEOs are reviewed annually by our Compensation Committee, typically in connection with our annual performance review process, and adjusted from time to time, based on the recommendation of the Compensation Committee, to realign salaries with market levels after taking into account individual responsibilities, performance and experiences. For 2025, base salary increases for the NEOs ranged from 3% to 6% after consideration of the foregoing factors. The 2025 base salaries of our NEOs are set forth in the table below:

Annual Cash Bonus

Our Compensation Committee approves annual cash bonuses for our NEOs (other than our CEO, whose annual cash bonus is determined by the Board) based on Company performance as compared to the corporate performance goals and objectives established by the Board at the beginning of each year or as otherwise determined appropriate. This annual cash incentive plan was established to motivate our executive officers to achieve short-term financial and business objectives, supporting our “pay-for-performance” culture and tying a significant portion of NEO compensation directly to Company achievements.

All NEOs are assigned annual bonus targets, expressed as a percentage of base salary, based on each NEO’s accountability, scope of responsibilities, and potential impact on performance, as well as peer group competitive data for similarly situated positions. Based on this review process, the Compensation Committee increased the annual bonus target for Dr. Henderson from 55% to 65% for the 2025 fiscal year. The target bonus percentage for Dr. Dambkowski and Ms. Henderson did not change between 2024 and 2025. The table below sets forth the target bonus for each NEO:

The overall amount of the annual cash incentive plan pool each performance year is determined by the Compensation Committee and is generally based on (i) the individual’s target bonus, as a percentage of base salary and (ii) the percentage attainment of our corporate goals as established by the Compensation Committee, subject to the Compensation Committee’s discretion. Payouts under the annual cash incentive plan are not guaranteed, and the Compensation Committee may decide that payouts are as low as zero for a year of poor Company performance or may decide that payouts exceed target performance for a year of exceptional Company performance. For 2026, we have shifted the bonus weighting from 100% corporate to 80% corporate and 20% individual for the NEOs other than the CEO.

At the time the 2025 corporate objectives were determined, the Compensation Committee believed that payout at the target performance level was challenging but achievable and that payout above target represented true “stretch” performance goals. All awards are reviewed and approved by the Compensation Committee.

The pre-established corporate objectives for 2025 and their bonus payout are described in the table below. This table does not include the target levels with respect to the specific quantitative and qualitative objectives, as we believe disclosure of such information would result in competitive harm to the Company.

In reviewing the Company’s performance against the pre-established 2025 corporate objectives, in December 2025, the Compensation Committee approved a corporate goal achievement of 130%, which was based on: the Zumilokibart Program Achievements, the APG279 Program Achievements, the APG273 Program Achievement, the APG808 Program Achievement and the Finance Achievements.

The Board approved Dr. Henderson’s payout under the annual cash incentive plan at 130% of target. As a result, the annual cash incentive plan payouts approved by the Compensation Committee and the Board for 2025 were as follows:

Long-Term Incentive Compensation

Our equity grant program is intended to recognize the contributions of our NEOs to the achievement of corporate objectives, to create a greater sense of employee ownership, to align their interests with those of our stockholders by creating value tied to the performance of our stock price, and for retention purposes. In determining the form and value of an annual grant, the Compensation Committee considers the contributions and responsibilities of each NEO, appropriate incentives for the achievement of our long-term growth, the size and value of grants made to other executives at peer companies holding comparable positions, individual achievement of designated performance goals, and our overall performance relative to corporate objectives. The Compensation Committee also may grant equity awards to new executive officer hires or special awards upon promotion or for retention. We generally approve annual equity awards in the final month of each calendar year. In December 2024, we approved annual equity awards, which grants became effective at the time of grant in December 2024. In December 2025, we approved annual equity awards, which grants became effective in January 2026, which we expect to be the new grant schedule going forward.

Stock Options

For 2025, the Compensation Committee further determined that, after evaluating current compensation trends, reviewing the intended purpose of long-term equity incentive compensation, and considering the Company’s stage of development as a growing biopharmaceutical company and related market practice, the long-term equity incentive awards for NEOs should continue to consist solely of stock options. Stock options are inherently performance based, as they only provide value to the participant when the stock price appreciates over time, and typically have a four-year vesting schedule, which provides a retention component. The Compensation Committee continues to evaluate the appropriate mix of equity awards in light of the Company’s stage of development, business strategy, operational and

clinical development results, competitive market conditions in the industry, and Peer Group practices. In 2024, in consideration of the foregoing factors, and in recognition of 2024 performance, the Compensation Committee granted options to the NEOs in December 2024. And, in January 2026, the Compensation Committee granted options to the NEOs based on 2025 performance. As a result, the Company did not grant any stock options to the NEOs, and the Summary Compensation Table does not reflect stock option grants for 2025. The Company anticipates granting NEO equity awards at the beginning of 2027, in recognition of prior year 2026 performance and to incentivize future performance.

The table below sets forth the options granted to NEOs in 2024.

The table below sets forth the options granted to NEOs in 2026.

Each stock option represents the right to purchase one share of Common Stock at the option exercise price (once the option is vested). The stock options granted to the NEOs in 2024 based on 2024 performance and in 2026 based on 2025 performance vest over four years on a monthly basis, until fully vested on the fourth anniversary. The stock options expire 10 years after the date of the grant. This provides a reasonable timeframe during which the NEOs can benefit from the appreciation of the Company’s shares. The exercise price of the stock options was equal to the fair market value of the underlying stock on the date of grant.

Other Elements of Compensation

Benefits and perquisites

We offer participation in broad-based retirement, health and welfare plans to all of our employees. We pay the premiums for basic life and disability insurance for all of our employees, including our NEOs. All employees, including NEOs, are eligible to participate in a variety of ancillary benefits, including dental, vision, flexible spending accounts, health savings accounts, paid time off benefits, and an employee stock purchase plan. We currently maintain a retirement plan intended to provide benefits under section 401(k) of the Internal Revenue Code in which employees, including the NEOs, are allowed to contribute portions of their eligible compensation to a tax-qualified retirement account. Effective January 1, 2024, we established a 401(k) matching program which enables our employees, including the NEOs, to receive a dollar-for-dollar Company match of up to 4% of his or her compensation to the 401(k) fund, subject to limitations under applicable law. All of our employees are eligible to participate in the 401(k) plan on the same terms as our NEOs. We do not sponsor any qualified or non-qualified defined benefit plans for any of our employees or NEOs.

Employment Agreements

Each of the Company’s NEOs is covered by an employment agreement providing for a minimum annual level of salary, target incentives, and benefit eligibility. The agreements also provide for a severance benefit upon certain terminations of employment pursuant to the terms of the Executive Severance Policy, as described below under the subsection titled “Potential Payments Upon Termination or Change in Control.” It is the Compensation Committee’s belief that the employment agreements are necessary from a competitive perspective and contribute to the stability of the management team.

Other Policies

Clawback Policy

In July 2023, we adopted a clawback policy intended to comply with the requirements of Nasdaq Listing Standard 5608 implementing Rule 10D-1 under the Exchange Act. In the event the Company is required to prepare an accounting restatement of the Company’s financial statements due to material non-compliance with any financial reporting requirement under the federal securities laws, the Company will seek to recover, on a reasonably prompt basis, the excess incentive-based compensation received by any covered executive, including our NEOs, during the prior three fiscal years that exceeds the amount that the executive otherwise would have received had the incentive-based compensation been determined based on the restated financial statements.

In addition, in any instance in which, in the view of the Compensation Committee, a covered executive engaged in an act of fraud or misconduct that contributed to the need for a financial restatement, the Compensation Committee may, in its discretion, recover and the covered executive shall forfeit or repay, all of the covered executive’s incentive-based compensation for the relevant period, plus a reasonable rate of interest.

Insider Trading, Anti-Hedging, and Anti-Pledging Policy

We have adopted an insider trading policy governing the purchase, sale and other dispositions of our securities that applies our executive officers, directors, employees and certain designated consultants and contractors, as well as to the Company. We believe that our insider trading policy and repurchase procedures are reasonably designed to promote compliance with insider trading laws, rules and regulations, and listing standards applicable to us.

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 stockholders. 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, non-public information or otherwise is not permitted to trade in Company securities. Our insider trading policy expressly prohibits covered persons from engaging in any short sales of our stock, any transactions involving publicly traded options or other derivatives and any hedging transactions. Our insider trading policy also expressly prohibits our officers and directors from pledging Company securities as collateral for a loan.

Equity Grant Policies and Practices

Risk Management

During fiscal year 2025, our Compensation Committee reviewed our compensation policies in order to determine whether any such programs were likely to present a material risk to the Company. As part of its assessment, the Compensation Committee considered, among other things, our general compensation design philosophy, the total compensation levels and market data benchmarking, allocation of compensation among base salary and short- and long-term compensation, our approach to establishing Company-wide and individual performance targets, our equity plan design, including the emphasis on stock options as a significant compensation delivery vehicle, and our risk mitigation strategies. As a result of this review and analysis, the Compensation Committee determined that our policies and programs do not encourage excessive or inappropriate risk taking, and that they do not create risks that are reasonably likely to have a material adverse effect on the Company.

Compensation Committee Interlocks

None of the members of our Compensation Committee has at any time since our inception been one of our officers or employees. 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 of any entity that has one or more executive officers serving on our Board or Compensation Committee.

Compensation Committee Report

The Compensation Committee has reviewed and discussed with management the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K. Based on this review and discussion, the Compensation Committee recommended to the Board of Directors that the foregoing Compensation Discussion and Analysis be included in this Proxy Statement and incorporated by reference in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

EXECUTIVE COMPENSATION TABLES

2025 Summary Compensation Table

The following table sets forth the total compensation that was awarded to, earned by or paid to our NEOs for services rendered during the years ended December 31, 2023, 2024 and 2025 (respectively, the “2023 Fiscal Year”, “2024 Fiscal Year” and the “2025 Fiscal Year”).

2025 Grants of Plan-Based Awards Table

The following table sets forth certain information with respect to 2025 plan-based awards granted to the NEOs during the year ended December 31, 2025. Due to the timing of our long-term incentive grants, no options were granted to our NEOs in 2025.

Outstanding Equity Awards at 2025 Fiscal Year-End Table

The following table summarizes equity awards held by our NEOs as of the end of the 2025 Fiscal Year. Prior to the IPO, our NEOs each held incentive units pursuant to the LLC Agreement, which were exchanged for shares of common stock (with respect to vested incentive units) or restricted common stock awards (with respect to unvested incentive units) in connection with our IPO. Each of the equity awards in the table below may be subject to accelerated vesting, as described below under the subsection titled “Additional Narrative Disclosure - Potential Payments Upon Termination or Change in Control.”

Option Exercises and Stock Vested Table

The following table sets forth information regarding the option awards exercised and stock awards that vested for our NEOs during fiscal 2025.

Potential Payments Upon Termination or Change in Control

The table below reflects the amount of compensation that would become payable to each of the NEOs under existing plans and arrangements if that NEO’s employment had terminated on December 31, 2025 (pursuant to the executive’s employment agreement then in effect) and/or a change of control had occurred on such date, given the NEO’s compensation levels as of such date and, if applicable, based on the Company’s closing stock price on that date of $75.48. These benefits are in addition to benefits available prior to the occurrence of any termination of employment, including benefits generally available to salaried employees, such as distributions under the Company’s 401(k) plan. The actual amounts that would be paid upon an NEO’s termination of employment can be determined only at the time of such NEO’s separation from the Company. Due to the number of factors that affect the nature and amount of any benefits provided upon the events discussed below, any actual amounts paid or distributed may be higher or lower than reported below.

Executive Severance Policy

We maintain an executive severance policy that covers Dr. Henderson, Dr. Dambkowski, and Ms. Henderson (as amended, the “Executive Severance Policy”). Potential payments in connection with a change in control to each of Dr. Henderson, Dr. Dambkowski, and Ms. Henderson are governed by the Executive Severance Policy.

Under the Executive Severance Policy, Dr. Henderson is eligible to receive upon a termination by us without cause (as defined below) or a resignation for good reason (as defined below) that is not within the change in control period (as defined below): (i) 1.5 times his annual base salary, (ii) payment of any bonus amount earned but unpaid for the year prior to the year of termination, (iii) payment of a pro-rata portion of the target bonus that he would have earned for the year in which the termination occurs, (iv) subsidized continued health coverage for up to 18 months, and (v) the immediate acceleration of 30% of his equity-based awards. In addition, upon a termination by us without cause or a resignation for good reason, occurring within the change in control period, Dr. Henderson will be eligible to receive: (i) 1.5 times his annual base salary, (ii) payment of any bonus amount earned but unpaid for the year prior to the year of termination, (iii) payment of the full target bonus he would have earned for the year in which the termination occurs, (iv) subsidized continued health coverage for up to 18 months, and (v) the immediate acceleration of 100% of his equity-based awards.

Under the Executive Severance Policy, Dr. Dambkowski and Ms. Henderson are eligible to receive upon a termination by us without cause or a resignation for good reason (as defined below) that is not within the change in control period: (i) 1.0 times annual base salary, (ii) payment of any bonus amount earned but unpaid for the year prior to the year of termination, (iii) payment of a pro-rata portion of the target bonus that he or she would have earned for the year in which the termination occurs, and (iv) subsidized continued health coverage for up to 12 months. In addition, upon a termination by us without cause or a resignation for good reason, occurring within the change in control period, Dr. Dambkowski and Ms. Henderson will be eligible to receive the benefits listed in items (i), (ii), and (iv) and the payment of the full target bonus he or she would have earned for the year in which the termination occurs and the immediate acceleration of 100% of his or her equity-based awards.

For purposes of the Executive Severance Policy, the following definitions apply:

CEO PAY RATIO

Pursuant to Item 402(u) of Regulation S-K, we are required to calculate and disclose the annual total compensation of our median employee (excluding our CEO, Dr. Henderson), the annual total compensation of Dr. Henderson, and the ratio of these two amounts.

Our median employee was identified using the entire population of our employees as of December 31, 2025 based on a consistently applied compensation measure (“CACM”), that reasonably reflects the annual compensation of our employees. The CACM selected by us for our disclosure included the total cash compensation and the grant-date fair value for equity awards granted in fiscal 2025.

Based on the CACM methodology described above, we identified the median employee and calculated the fiscal 2025 compensation for this selected employee in the same manner we determine the annual total compensation of our NEOs for purposes of the Summary Compensation Table. The median employee’s fiscal 2025 annual total compensation was $283,326. Dr. Henderson’s fiscal 2025 annual total compensation as disclosed in the 2025 Summary Compensation Table was $1,291,500. As a result, our CEO to median employee pay ratio for fiscal 2025 is 5:1.

This pay ratio is a reasonable estimate calculated in a manner consistent with the SEC requirements, described above, and based on our payroll and employment records. As a result of a variety of factors, including employee populations, potential differences in the components used for the CACM, compensation philosophies and certain assumptions, pay ratios reported by other companies may not be comparable to our pay ratio. The pay ratio is not utilized by our management or our Compensation Committee for compensation-related decisions.
