Replimune Group (NASDAQ: REPL) seeks approval to double authorized stock

Rhea-AI Filing Summary

Replimune Group, Inc. is asking stockholders at its fully virtual 2026 annual meeting to approve three proposals, including an amendment to its charter to increase authorized common stock from 150,000,000 to 300,000,000 shares, requiring at least 75% approval of outstanding shares present and entitled to vote.

Stockholders will also vote on ratifying PricewaterhouseCoopers LLP as independent auditor for the fiscal year ending March 31, 2027 and a non-binding advisory “Say on Pay” vote on compensation for named executives for the year ended March 31, 2026.

The meeting is set for September 15, 2026 at 8:30 a.m. Eastern Time, with a record date of July 21, 2026. Two Class II directors (Paolo Pucci and Veleka R. Peeples-Dyer) are not standing for reelection, creating vacancies under the company’s classified board structure. The proxy also details board and committee composition, independence determinations, director cash and equity compensation, and governance policies including an insider trading policy, anti-hedging and pledging restrictions, and a Dodd-Frank–compliant clawback policy. Replimune reports that it qualifies as a smaller reporting company, allowing reduced disclosure obligations.

Key Terms

broker non-votes, classified board, Say on Pay Proposal, smaller reporting company, +1 more

5 terms

broker non-votes regulatory

"Broker non-votes will not be treated as votes cast for this purpose"

Broker non-votes occur when a brokerage firm is unable to vote on a shareholder’s behalf during a company election or decision because the shareholder has not given specific voting instructions, and the broker is not allowed or chooses not to vote on certain matters. They are important because they can affect the outcome of votes, especially when the results are close, by effectively reducing the total number of votes cast.

classified board regulatory

"Our Third Amended and Restated Certificate of Incorporation provides that our Board is divided"

A classified board is a company board structure where directors are split into groups that stand for election in different years, so only a portion of directors can be replaced at any one annual meeting. This is like changing only a few players on a sports team each season rather than swapping the whole roster at once; for investors it matters because it slows down large-scale board changes, affecting how quickly shareholders can push for new leadership or respond to takeover offers and thereby influencing governance risk and valuation.

Say on Pay Proposal regulatory

"the compensation of the Company’s named executive officers as disclosed in this Proxy Statement (the “Say on Pay Proposal”)"

smaller reporting company regulatory

"We are a “smaller reporting company” as that term is defined in Regulation S-K"

A smaller reporting company is a publicly traded firm that meets regulatory size tests allowing it to provide abbreviated financial disclosures and compliance filings compared with larger companies. For investors, that means financial statements and notes may be less detailed, which can make it harder to compare performance or spot risks—think of reading a short summary instead of a full report when deciding whether to buy or hold a stock.

clawback policy regulatory

"The Clawback Policy provides for the recovery or “clawback” of certain erroneously awarded"

A clawback policy is a company rule that lets the firm take back pay, bonuses or stock awards from current or former executives if results are later found to be incorrect, misconduct occurred, or targets were missed. It matters to investors because it helps protect the value of their holdings by discouraging risky or fraudulent behavior and ensuring executive rewards reflect real, verified performance—think of it as a return policy for executive pay.

FAQ

When is Replimune (REPL) holding its 2026 annual stockholder meeting?

Replimune will hold its 2026 annual meeting on September 15, 2026 at 8:30 a.m. Eastern Time as a fully virtual meeting via live webcast. Stockholders of record at the close of business on July 21, 2026 are entitled to notice and to vote.

What key proposals will Replimune (REPL) stockholders vote on in 2026?

Stockholders will vote on three company proposals: ratifying PricewaterhouseCoopers LLP as auditor for the year ending March 31, 2027, a non-binding advisory vote on executive compensation for fiscal 2026, and amending the charter to increase authorized common stock from 150,000,000 to 300,000,000 shares.

How many authorized shares will Replimune (REPL) have if Proposal 3 is approved?

If Proposal 3 is approved, Replimune’s authorized common stock will increase from 150,000,000 shares to 300,000,000 shares. This change amends the Third Amended and Restated Certificate of Incorporation but does not by itself issue any new shares or set specific issuance terms.

What voting threshold applies to Replimune (REPL) Proposal 3 on increasing authorized shares?

Proposal 3 requires the affirmative vote of at least 75% of the outstanding shares of capital stock present in person or represented by proxy at the meeting and entitled to vote. Abstentions count as present and entitled to vote, so they have the effect of votes against the proposal.

How are Replimune (REPL) non-employee directors compensated?

For fiscal 2026, each non-employee director received an annual cash retainer of $45,000, while the Chairperson received $80,000, plus additional cash for committee roles. On April 1, 2025 each continuing non-employee director also received stock options for 32,000 shares vesting after one year.

What does it mean that Replimune (REPL) is a smaller reporting company?

Replimune states it qualifies as a smaller reporting company under SEC rules, generally based on public float and revenue thresholds. This status allows reduced disclosure compared with larger issuers, particularly around executive compensation and certain financial information, while still complying with applicable securities laws.

What board changes are highlighted in Replimune’s (REPL) 2026 proxy?

Two Class II directors, Paolo Pucci and Veleka R. Peeples-Dyer, are not being renominated, so their terms end at the 2026 meeting and two Class II vacancies will be created. Replimune is maintaining its classified board structure with staggered multi-year terms for remaining directors.

We may solicit proxies by mail, personal interview, telephone or via the Internet through its officers,

directors and other management employees, who will receive no additional compensation for their services. We may also request that brokers, nominees, custodians and other fiduciaries forward soliciting materials to the beneficial owners of shares held by the brokers, nominees, custodians and other fiduciaries. We will reimburse these persons for their reasonable expenses in connection with these activities.

Pursuant to rules and regulations adopted by the SEC, we have elected to deliver the Internet Notice to stockholders and provide Internet access to our proxy materials. Stockholders may obtain paper copies of the proxy materials free of charge by following the instructions provided in the Internet Notice.

Can I change or revoke my vote?

You may revoke your proxy at any time before it is voted by delivering written notice to our Investor Relations team at our principal executive offices, by returning a signed proxy with a later date, by transmitting a subsequent vote over the Internet or by telephone prior to the close of the Internet voting facility or the telephone voting facility, or by attending the Annual Meeting and voting electronically. If your stock is held in street name, you must contact your broker or nominee for instructions as to how to change or revoke your vote.

How is a quorum reached?

The presence of holders of at least a majority of the issued and outstanding shares entitled to vote is necessary to constitute a quorum for the transaction of business at the Annual Meeting. For purposes of determining whether a quorum exists, we count as present any shares that are voted over the Internet, by telephone or by completion and submission of a proxy or that are represented virtually at the Annual Meeting. Further, for purposes of establishing a quorum, we will count as present shares that a stockholder holds even if the stockholder votes to withhold or abstain or votes on only one of the proposals. In addition, we will count as present shares held in street name by brokers or other nominees that indicate on their proxies that they do not have authority to vote those shares on Proposal No. 2. If a quorum is not present, we expect to adjourn the Annual Meeting until we obtain a quorum.

What are broker non-votes?

“Broker non-votes” are shares represented at the Annual Meeting held by brokers, banks or other nominees (i.e., in “street name”) which do not vote on a particular proposal because the nominee does not have discretionary voting power with respect to such proposal because the matter is considered “non-routine” (or “non-discretionary”) and it has not received instructions from the beneficial owner. If you are a beneficial owner of shares held in street name and do not vote over the Internet, by phone or by mailing your proxy card, under the rules of various securities exchanges, the bank, broker or other nominee that holds your shares may generally vote your shares in their discretion on “routine” ​(or “discretionary”) matters in the absence of voting instructions from you, but they cannot vote your shares on “non-routine” matters.

Under applicable Nasdaq listing rules, we believe that the ratification of the selection of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for the fiscal year ending March 31, 2027 (Proposal No. 1) is considered a “routine” matter on which brokers are permitted to vote in their discretion even if you do not provide voting instructions with respect to such proposal.

Under applicable Nasdaq listing rules, we believe that the approval of the compensation of the Company’s named executive officers for the fiscal year ended March 31, 2026 (Proposal No. 2) is considered to be a “non-routine” item. Accordingly, if you hold your shares in street name and do not instruct your broker, bank or other nominee how to vote your shares on Proposal No. 2, your broker, bank or other nominee will not be permitted to vote your shares on such matter. This is a “broker non-vote.”

Under applicable Nasdaq listing rules, we believe that the approval of an amendment to the Third Amended and Restated Certificate of Incorporation of the Company to increase the number of authorized shares of common stock, par value $0.001 per share, from 150,000,000 shares to 300,000,000 shares (Proposal No. 3) is considered a “routine” matter on which brokers are permitted to vote in their discretion even if you do not provide voting instructions with respect to such proposal.

TABLE OF CONTENTS

What vote is required to approve each item?

Required Vote — Ratification of the Selection of Independent Registered Public Accounting Firm (Proposal No. 1).   The affirmative vote of a majority of shares of our common stock present or represented by proxy at the Annual Meeting and entitled to vote is required to ratify the selection of our independent auditors. An abstention is treated as present and entitled to vote and, therefore, has the effect of a vote “against” the ratification of the independent auditors. Because the ratification of the independent auditors is a routine matter, a nominee holding shares in street name may vote on this proposal in the absence of instructions from the beneficial owner.

Required Vote — Approval of Non-Binding Advisory Vote on the Compensation of the Company’s Named Executive Officers (Proposal No. 2).   The affirmative vote of a majority of shares of our common stock present or represented by proxy at the Annual Meeting and entitled to vote is required to approve, on a non-binding advisory basis, the compensation of the Company’s named executive officers for the fiscal year ended March 31, 2026 as disclosed in this Proxy Statement (the “Say on Pay Proposal”). An abstention is treated as present and entitled to vote and, therefore, has the effect of a vote “against” the Say on Pay Proposal. Broker non-votes will not be treated as votes cast for this purpose and, therefore, will not affect the outcome of the vote.

Required Vote — Approval of an Amendment to the Third Amended and Restated Certificate of Incorporation of the Company to Increase the Number of Authorized Shares of Common Stock, par value $0.001 per share, from 150,000,000 Shares to 300,000,000 Shares (Proposal No. 3).   The affirmative vote of at least seventy-five percent (75%) of the outstanding shares of our capital stock present in person or represented by proxy at the Annual Meeting and entitled to vote is required to approve an amendment to the Third Amended and Restated Certificate of Incorporation of the Company to increase the number of authorized shares of common stock, par value $0.001 per share, from 150,000,000 shares to 300,000,000 shares. An abstention is treated as present and entitled to vote and, therefore, has the effect of a vote “against” the proposal to amend the Third Amended and Restated Certificate of Incorporation of the Company to increase the number of authorized shares of common stock, par value $0.001 per share, from 150,000,000 shares to 300,000,000 shares. Broker non-votes will not be treated as votes cast for this purpose and, therefore, will not affect the outcome of the vote.

If the Annual Meeting is adjourned or postponed for any purpose, at any subsequent reconvening of the Annual Meeting, your proxy will be voted in the same manner as it would have been voted at the original convening of the Annual Meeting unless you withdraw or revoke your proxy.

Could other matters be decided at the Annual Meeting?

Stockholders at an annual meeting will only be able to consider proposals or nominations specified in the Notice of Annual Meeting or brought before such annual meeting by or at the direction of our Board or by a stockholder of record on the Record Date for the meeting who is entitled to vote at the meeting and who has delivered timely written notice in proper form of the stockholder’s intention to bring such business before the meeting. As of the date of this Proxy Statement, Replimune does not know of any other business that may be presented for action at the Annual Meeting. Should any other business properly come before the Annual Meeting, the persons named on the enclosed proxy will have discretionary authority to vote the shares represented by such proxies in accordance with their best judgment to the same extent as the person signing the proxy would be entitled to vote. If you hold shares through a broker, bank or other nominee, as described above, they will not be able to vote your shares on any other business that comes before the Annual Meeting unless they receive instructions from you with respect to such matter.

Why hold a virtual Annual Meeting?

We believe that hosting a virtual meeting this year is in our best interest and the best interest of our stockholders, primarily because we believe a virtual meeting enables increased stockholder attendance and participation because stockholders can participate from any location around the world. You will be able to attend the Annual Meeting online and submit your questions by visiting www.meetnow.global/MP4F5JS. You also will be able to vote your shares electronically at the Annual Meeting by following the instructions above.

TABLE OF CONTENTS

What if during the check-in time or during the Annual Meeting I have technical difficulties or trouble accessing the virtual meeting website?

We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual meeting website, and the information for assistance will be available during the meeting.

What happens if the meeting is postponed or adjourned?

Your proxy may be voted at the postponed or adjourned meeting. You will still be able to change your proxy until it is voted.

What does it mean if I receive more than one proxy card or voting instruction form?

It means that you have multiple accounts with Computershare or with brokers. Please complete and return all proxy cards or voting instruction forms to ensure that all of your shares are voted.

Where can I find the voting results of the Annual Meeting?

The preliminary voting results will be announced at the Annual Meeting. The final results will be disclosed in a Current Report on Form 8-K filed with the SEC within four business days after the date of the Annual Meeting.

What are the implications of being a “smaller reporting company”?

We are a “smaller reporting company” as that term is defined in Regulation S-K. We will remain a smaller reporting company if we have (1) less than $250 million in market value of our shares held by non-affiliates as of the last business day of our second fiscal quarter or (2) less than $100 million of annual revenues in our most recent fiscal year completed before the last business day of our second fiscal quarter and less than $700 million in market value of our shares held by non-affiliates as of the last business day of our second fiscal quarter. As a “smaller reporting company,” we are subject to reduced disclosure obligations as compared to other issuers, including with respect to disclosure obligations regarding executive compensation in our periodic reports and proxy statements and certain reduced financial information disclosure.

Who should I call if I have any additional questions?

If you hold your shares directly, please call Investor Relations at +1 (339) 970-2843. If your shares are held in street name, please contact the telephone number provided on your voting instruction form or contact your broker or nominee holder directly.

BOARD OF DIRECTORS

Board Composition and Structure

Our Third Amended and Restated Certificate of Incorporation and bylaws, each as amended and currently in effect, state that our Board will consist of a number of directors that will be fixed exclusively by the Board from time to time in accordance with the bylaws of the Company. Each director holds office until his or her successor is duly elected and qualified or until his or her death, incapacity, resignation or removal. Our Third Amended and Restated Certificate of Incorporation, as amended and currently in effect, provides that our directors may be removed only for cause by the affirmative vote of the holders of at least 75% of the voting power of the outstanding shares of our capital stock entitled to vote in the election of directors, voting together as a single class, at a meeting of the stockholders called for that purpose. Any vacancy in the Board, including a vacancy that results from an increase in the number of directors, may be filled only by the vote of a majority of the remaining directors then in office, although less than a quorum, or by the sole remaining director.

Our Third Amended and Restated Certificate of Incorporation, as amended and currently in effect, provides that our Board is divided into three classes of directors, Class I, Class II, and Class III, such classes to be as nearly equal in number of directors as possible, having staggered three-year terms of office. Paolo Pucci and Veleka R. Peeples-Dyer are the Class II directors whose terms expire at the Annual Meeting. After thoughtful consideration the Board has decided not to nominate Mr. Pucci and Ms. Peeples-Dyer for reelection as Class II directors at the Annual Meeting. Accordingly, no directors will be elected to constitute Class II of the Board at the Annual Meeting, and two Class II directorship vacancies will be created following the Annual Meeting. Each vacancy will remain unfilled unless and until our Board appoint a director to fill such vacancy in accordance with our Third Amended and Restated Certificate of Incorporation and bylaws, each as amended and currently in effect. All continuing directors will remain in office for the remainder of their respective terms and until their successors are duly elected and qualified, or until their earlier resignation, retirement or removal in accordance with the Company’s Third Amended and Restated Certificate of Incorporation and bylaws. We believe our Board and committees of the Board Committees are appropriate at this stage of the Company’s development, given the nature, structure and complexity of our operations. The Board, under the advisement of the Nominating and Corporate Governance Committee, will continue to evaluate the size, composition and structure of the Board and committees of the Board to ensure we maintain the expertise necessary to oversee the Company’s evolving strategy and key business initiatives.

Each of our directors identified below serves in the class indicated opposite such director’s name. Subject to any earlier resignation or removal in accordance with the terms of our Third Amended and Restated Certificate of Incorporation and bylaws, each as amended and currently in effect, our current Class I directors will serve until the 2028 Annual Meeting of Stockholders; and our current Class III directors will serve until the 2027 Annual Meeting of Stockholders. Any additional directorships resulting from an increase in the number of directors will be apportioned by our Board.

Our Board is currently composed of ten members. Below is a list of the names, ages as of July 21, 2026 and classification of the individuals who currently serve as our directors.

Name	​	​	Age	​	​	Position(s)	​	​	Class	​

Recent Board Composition Changes

The Board did not nominate Mr. Pucci and Ms. Peeples-Dyer for reelection at the Annual Meeting. Accordingly, no directors will be elected to constitute Class II of the Board at the Annual Meeting. As a result, two Class II directorship vacancies will be created following the Annual Meeting. Each vacancy will remain unfilled unless and until the Board appoints a director to fill such vacancy in accordance with our Third Amended and Restated Certificate of Incorporation and bylaws, each as amended and currently in effect.

Classified Board

In consultation with our Nominating and Corporate Governance Committee, the Board has determined that the classified board structure remains appropriate at this time. A classified board provides for stability, continuity and experience among our Board. Further, the Board believes that building a cohesive board is an important goal. In our industry in particular, long-term focus is critical. The time horizon required for successful development of biologics makes it vital that we have a board that understands the implications of this process and has the ability to develop and implement long-term strategies while benefiting from an in-depth knowledge of our business and operations. A classified board structure helps to ensure that there will be the continuity and stability of leadership required to navigate a challenging development environment while resisting the pressure to focus on short-term results at the expense of our long-term value and success. Our future success depends in significant part on the ability to attract and retain capable and experienced directors. In this regard, we believe that longer terms for our directors enhances director independence from both management and stockholder special interest groups.

Director Biographies

Information concerning our current directors is set forth below. The biographical description of each current director includes the specific experience, qualifications, attributes and skills that led the Board to conclude that such person should serve as a director.

From February 2007 to October 2007, Mr. Balachandran was Vice President, Site Operations, and from October 2007 to August 2012, he held the position of Senior Vice President, Manufacturing. Prior to his tenure at Amgen, Mr. Balachandran held leadership positions at Copley Pharmaceuticals, now a part of Teva Pharmaceuticals Industries Ltd., and Burroughs Wellcome Company, a predecessor before mergers of GlaxoSmithKline plc. Mr. Balachandran currently serves as a director of Incog, Inc., A2 Biotherapeutics, Inc. and ADRX, Inc., each a private company.

CORPORATE GOVERNANCE

Director Independence

Under the rules and regulations of The Nasdaq Stock Market LLC (“Nasdaq”) a majority of a listed company’s board of directors must be composed of independent directors. In addition, Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit committee and compensation committee be independent and satisfy additional independence criteria set forth in Rules 10A-3 and 10C-1, respectively, under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Under Nasdaq listing rules, a director will only qualify as an “independent director” if, in the opinion of that 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.

Based upon information requested from and provided by our directors concerning their background, employment and affiliations, including family relationships, our Board has determined, upon the recommendation of our Nominating and Corporate Governance Committee, that each of our continuing directors, other than Sushil Patel, our Chief Executive Officer, and Philip Astley-Sparke, our Executive Chairman, has no relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and is independent within the meaning of the director independence standards of Nasdaq and SEC rules and regulations. Our Board has also determined that each of the current members of our Audit Committee and our Compensation Committee as set forth in the “Board Committees” section below satisfies the independence standards for such committee. In making such determination, our Board considered the relationships that each non-employee director has with Replimune and all other facts and circumstances deemed relevant in determining their independence.

There are no family relationships among any of our directors or executive officers.

Board Meetings, Attendance and Executive Sessions

The Board held nineteen meetings and took action by written consent twice during the fiscal year ended March 31, 2026. All Board members attended at least 75% of the meetings of the Board and the committees of the Board on which they served. Executive sessions, or meetings of the outside (nonmanagement) directors without management present, are held regularly. The non-management directors met in executive session during five of the Board meetings during the fiscal year ended March 31, 2026. We encourage our directors to attend our Annual Meeting of Stockholders, which we have historically held immediately after a meeting of the Board. Philip Astley-Sparke, Sushil Patel, Dieter Weinand, Joseph Slattery, Veleka R. Peeples-Dyer, Kapil Dhingra, Christy Oliger, Paolo Pucci, Michael Goller, and Madhavan Balachandran attended our 2025 Annual Meeting of Stockholders via teleconference.

Board of Directors Leadership Structure

Our current leadership structure is comprised of an Executive Chairman, a Chief Executive Officer and a lead independent director. This structure was implemented in connection with Dr. Patel’s promotion to Chief Executive Officer on April 1, 2024. In connection with Dr. Patel’s promotion, Mr. Philip-Astley Sparke transitioned from chief executive officer to our Executive Chairman and Mr. Dieter Weinand from chairperson of our Board to our lead independent director. Our current corporate governance structure was effected to allow our Chief Executive Officer to focus on our day-to-day business, our Executive Chairman to lead our Board in its fundamental role of providing advice to, and independent oversight of, management while, at the same time, assisting our Chief Executive Officer in his day-to-day management duties, and a lead independent director of the Board to provide an additional measure of balance, to ensure the Board’s independence, and to enhance the Board’s ability to fulfill its management oversight responsibilities. Our Board believes that having these three separate positions is the appropriate leadership structure for us and demonstrates our commitment to good corporate governance.

The Board of Directors’ Role in Risk Oversight

Our management team is responsible for the day-to-day management of the risks we face, while our Board, as a whole and through committees, has responsibility for the oversight of risk management. Our

13

TABLE OF CONTENTS​​

Board performs this oversight role by using several different levels of review. In connection with its reviews of the operations and corporate functions of our company, our Board addresses the primary risks associated with those operations and corporate functions. In addition, our Board reviews the risks associated with our company’s business strategies periodically throughout the year as part of its consideration of undertaking any such business strategies.

The role of the Board in overseeing the management of our risks is conducted primarily through committees of the Board, as described in the descriptions of each of the committees below and in the charters of each such committee. The full Board (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 impacts 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 during the committee reports portion of the next Board meeting. This enables the Board and its committees to coordinate the risk oversight role, particularly with respect to risk interrelationships.

The Board of Directors’ Role in Cybersecurity Risk Oversight

Our Audit Committee has primary responsibility for management and mitigation of the cybersecurity and information technology risks facing our Company. As part of the Board’s role in overseeing our risk management program, the Audit Committee and Board devote time and attention to cybersecurity-related risks. Specifically, the Audit Committee and Board receive reports on cybersecurity and information technology matters, and related risk exposures, initiatives, and readiness programs, among others, from management. The Audit Committee also regularly updates the Board on such matters.

Board Committees

Our Board has established an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee, and a Research & Development Committee, each of which operates pursuant to a charter adopted by our Board. Each committee reviews and assesses the adequacy of its charter at least annually and recommends any proposed changes to the Board for approval. The charters for each of our Board committees are all available on our website at www.replimune.com under “Investors & Media” at “Corporate Governance.”

The current composition and responsibilities of each committee are described below. Members serve on these committees until their resignation or until otherwise determined by our Board. Following the Annual Meeting, the Board intends to assess the size and composition of one or more of the Board committees. This process will reflect the anticipated changes in Board composition, including the departures of Mr. Pucci and Ms. Peeples-Dyer.

The following table describes which directors currently serve on each of the Board committees.

In addition, the Nominating and Corporate Governance Committee develops and implements our corporate governance guidelines, reviews and assesses the adequacy of our Third Amended and Restated Certificate of Incorporation, bylaws and committee charters, oversees compliance with our code of business conduct and ethics and our insider trading policy, and contributes to succession planning.

Policies Governing Director Nominations

Director Nomination Process

Our Board is responsible for selecting its own members. The Board delegates the selection and nomination process to the Nominating and Corporate Governance Committee, with the expectation that other members of the Board and of management will be requested to take part in the process as appropriate. The Nominating and Corporate Governance Committee makes recommendations to the Board regarding the size and composition of the Board. The Nominating and Corporate Governance Committee reviews annually with the Board the composition of the Board as a whole and recommends, if necessary, measures to

16

TABLE OF CONTENTS

be taken so that the Board reflects the appropriate balance of expertise, experience, qualifications, and skills required for the Board as a whole and contains at least the minimum number of independent directors required by applicable laws, rules and regulations. Unless determined otherwise by the Board, the Nominating and Corporate Governance Committee recommends, and the Board nominates, candidates to stand for election as directors.

Generally, our Nominating and Corporate Governance Committee identifies candidates for director nominees in consultation with management, through the use of search firms or other advisors, through recommendations submitted by stockholders or through such other methods as the Nominating and Corporate Governance Committee deems to be helpful to identify candidates. Once candidates have been identified, our 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, 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 qualifications and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of the Board. Based on the results of the evaluation process, the Nominating and Corporate Governance Committee recommends to the Board for approval candidates as director nominees for election to the Board.

Stockholders may also nominate persons to be elected as directors. The Nominating and Corporate Governance Committee will consider director candidates recommended by our stockholders in accordance with our bylaws. If a stockholder wishes to nominate a person for election as director, such stockholder must follow the procedures contained in our bylaws. In evaluating candidates recommended by our stockholders, the Nominating and Corporate Governance Committee applies the same criteria set forth below under “Minimum Qualifications.” To nominate a person to stand for election as a director, a stockholder must provide our Secretary with timely notice of the nomination and the notice must include the information required by Section 2.12(b) of our bylaws. In addition, stockholders who intend to solicit proxies in support of director nominees other than the company’s nominees must also comply with the additional requirements of Rule 14a-19(b) under the Exchange Act.

Additional information regarding requirements for stockholder nominations for next year’s annual meeting is described in this Proxy Statement under “General Matters — Stockholder Proposals and Nominations.”

Minimum Qualifications

In considering whether to recommend any particular candidate for inclusion in the slate of recommended director nominees for the Board, our Nominating and Corporate Governance Committee may consider certain criteria set forth in the Nominating and Corporate Governance Committee Charter. These criteria include the Board’s size and current composition; corporate governance policies; applicable Nasdaq listing standards and SEC rules and regulations; a candidate’s individual director performance, and willingness to serve actively; the number of other public and private boards on which a candidate sits; and the absence of potential conflicts with our interests. The Board does not assign specific weights to particular criteria and no particular criterion is a prerequisite for any prospective nominee.

In evaluating proposed director candidates (both proposed director candidates and current Board members), the Nominating and Corporate Governance Committee may consider, in addition to the minimum qualifications and other criteria for board membership approved by the Board from time to time, all facts and circumstances that it deems appropriate or advisable, including, among other things, the background and characteristics of the proposed nominee and his or her independence and the needs of the Board. Furthermore, our Nominating and Corporate Governance Committee’s priority in selecting Board members is the identification of persons who will further the interests of the Company through an established record of professional accomplishment, the ability to contribute positively to the collaborative culture among Board members, knowledge of our business, understanding the competitive landscape, and professional and personal experiences and expertise relevant to our growth strategy.

17

TABLE OF CONTENTS​

Additionally, the Nominating and Corporate Governance Committee considers numerous other qualities, skills and characteristics when evaluating director nominees, including whether the nominee has specific strengths that would augment existing skills and experience of the Board, such as expertise and experience in science & technology, healthcare provision & payment, regulatory, commercialization, pricing & reimbursement, public policy, finance & capital markets, talent management, biopharma manufacturing, compliance or international life science, and whether the nominee brings leadership experience as a chief executive officer/chief operating officer or board director within public companies or other complex organizations. The following matrix highlights each continuing director’s and nominee’s primary skills or knowledge in these areas as identified by the Nominating and Corporate Governance Committee. As the matrix focuses solely on primary skills and knowledge, the absence of a mark does not necessarily indicate that the director or nominee does not possess such skill or knowledge.

TABLE OF CONTENTS​​​​

Code of Business Conduct and Ethics and Corporate Governance Guidelines

We have adopted a code of business conduct and ethics that applies to all of our employees, including our executive officers and those employees responsible for financial reporting, and directors. The code of business conduct and ethics is available on our website at www.replimune.com under “Investors & Media” at “Corporate Governance”; or by requesting a copy, free of charge, in writing from Investor Relations at Replimune Group, Inc., 500 Unicorn Park Drive, Suite 303, Woburn, MA 01801. We intend to post on our website any amendment to, or waiver under, a provision of the code of business conduct and ethics that applies to certain of our executive officers within four business days following the date of such amendment or waiver.

A copy of our corporate governance guidelines may also be accessed free of charge by visiting our website at www.replimune.com under “Investors & Media” at “Corporate Governance” or by requesting a copy from Investor Relations at our principal executive offices above.

Insider Trading Policy

We have adopted an insider trading policy and procedures governing the purchase, sale, and/or other dispositions of our securities (the “Insider Trading Policy”) that applies to all directors, officers, and employees of the Company and its subsidiaries. With regard to the Company’s trading in its own securities, it is the Company’s policy to comply with the federal securities laws and the applicable exchange listing requirements. We believe that the Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations with respect to the purchase, sale and/or other dispositions of the Company’s securities, as well as any listing standards, rules and regulations applicable to us. A copy of the Insider Trading Policy was filed as Exhibit 19.1 to our Annual Report on Form 10-K for the year ended March 31, 2026.

Clawback Policy

Effective November 20, 2023, our Board approved and adopted our Replimune Group, Inc. Compensation Recoupment Policy (the “Clawback Policy”) in accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act and applicable Nasdaq listing rules, a copy of which was filed as an exhibit to the annual report on Form 10-K for the fiscal year ended March 31, 2026. The Clawback Policy provides for the recovery or “clawback” of certain erroneously awarded incentive-based compensation in the event that the Company is required to prepare an accounting restatement resulting from material noncompliance with financial reporting requirements under federal securities laws.

Policies and Practices Related to the Grant of Certain Equity Awards Close in Time to the Release of Material Non-Public Information

The Compensation Committee reviews and approves individual equity grants for the named executive officers and directors, as well as the total number of shares underlying grants made to all employees. The annual equity grants typically are reviewed and approved at the Compensation Committee’s regular meeting during the third quarter of the fiscal year, although sign-on equity awards are generally approved by the Compensation Committee at the time an executive officer commences employment with the Company. The grant date for the annual equity grants is typically the first day of the Company’s fiscal year (April 1st).

We do not grant equity awards in anticipation of the release of material nonpublic information that is likely to result in changes to the price of our common stock, and do not time the public release of such information based on award grant dates. The timing of any equity grants to executive officers or directors in connection with new hires, promotions, or other non-routine grants is tied to the event giving rise to the award (such as an executive officer’s commencement of employment or promotion effective date).

During the year ended March 31, 2026, there were no equity grants made to our executive officers during any period beginning four business days before the filing of a periodic report or current report disclosing material non-public information and ending one business day after the filing or furnishing of such report with the SEC.

Anti-Hedging and Pledging Policy

Pursuant to our Insider Trading Policy, we prohibit our employees, our executive officers, members of the Board, and certain consultants and contractors from engaging in any hedging or monetization transactions relating to our securities, including through the use of financial instruments such as prepaid variable forwards contracts, equity swaps, collars and exchange funds. We also prohibit our employees, our executive officers, members of the Board, and certain consultants and contractors from holding our securities in a margin account or otherwise pledging our securities as collateral for a loan.

DIRECTOR COMPENSATION

We pay our non-employee directors retainers in cash. We do not pay any compensation to our employee directors in connection with their service on our Board. The compensation that we pay to our employee directors is discussed in the “Executive Compensation” section of this Proxy Statement. For the fiscal year ended March 31, 2026, each non-employee director other than the Chairperson of the Board received an annual retainer fee of $45,000 paid in quarterly installments. The Chairperson of the Board received an annual retainer fee of $80,000 paid in quarterly installments. In addition, non-employee directors received the following, as applicable:

Non-Employee Director	​	​	Annual Fee				​
Chairperson of the Audit Committee	​	​	​	$	20,000	​	​
Member of the Audit Committee (other than chairperson)	​	​	​	$	10,000	​	​

Chairperson of the Research & Development Committee	​	​	​	$	15,000	​	​

We also reimburse our non-employee directors for reasonable travel and out-of-pocket expenses incurred in connection with attending Board and committee meetings.

On April 1 of each year, upon recommendation of the Compensation Committee and approved by the Board, each continuing non-employee director is eligible to receive an option grant to purchase shares of our common stock under our 2018 Omnibus Incentive Compensation Plan. On April 1, 2025, we awarded each continuing non-employee director options to purchase up to 32,000 shares of our common stock. All options held by our current Board members have vested or will vest in full upon the one-year anniversary of the date of grant.

The amounts reported in this column reflect the full grant date fair value for awards granted during each of the fiscal years ended March 31, 2025 and 2026. The grant date fair value was computed in accordance with Accounting Standards Codification Topic 718, Compensation — Stock Compensation. The assumptions we used in valuing these awards are described in Note 10 to our audited consolidated financial statements in our Annual Report on Form 10-K for the year ended March 31, 2026.

​

For awards that are subject to performance conditions, we report the grant date fair values based upon the probable outcome of such conditions consistent with our estimate of aggregate compensation cost to be recognized over the service period as determined under ASC 718, excluding the effect of estimated forfeitures. Accordingly, the performance-based RSUs granted in the fiscal year end March 31, 2026 are shown at target level attainment. The grant date fair value of the performance-based RSUs granted in the fiscal year ended March 31, 2026 assuming a 100% level of attainment are as follows: Mr. Patel, $644,180; Ms. Hill, $206,120; and Mr. Xynos, $206,120.

(2)

The amounts reported in this column represent bonuses based upon the achievement of company and individual performance objectives for each of the fiscal years ended March 31, 2026 and 2025, which were paid in April 2026 and April 2025, respectively.

​

Dr. Patel joined the Company as its full-time Chief Executive Officer on April 1, 2024. The reported compensation for the fiscal year ending March 31, 2026 reflects compensation actually received during such fiscal year. During the fiscal years ended March 31, 2025 and March 31, 2026, Dr. Patel received $13,402 and $6,654, respectively, in additional compensation in connection with the Company’s contribution to his 401(k) plan.

​

(4)

Ms. Hill joined the Company as its full-time Chief Financial Officer on September 18, 2023. The reported compensation for the fiscal years ending March 31, 2025 and March 31, 2026 reflects compensation actually received during such fiscal year.

​

Our executive compensation philosophy is to generally provide compensation and benefit levels that will attract, retain, motivate and reward a highly talented executive team within the context of responsible cost management; establish a direct link between our individual/team performance and results and our executives’ compensation; and align the interests and objectives of our executives with those of our stockholders by linking executive equity awards to stockholder value creation. The compensation philosophy for our executive officers is composed primarily of the following three main components: base salary, annual cash incentives and long-term equity incentives. As part of our annual evaluation of executive compensation, we have engaged Pearl Meyer, an independent executive compensation consultant, to provide advice and recommendations relating to our executive officer compensation arrangements. Pearl Meyer

assisted the Compensation Committee in evaluating our executive officer compensation for alignment with governance and market best practices, and to provide recommendations on the appropriate compensation philosophy to guide the Compensation Committee in determining executive officer compensation.

Base Salary

The base salaries for the fiscal year ended March 31, 2026 were determined for each named executive officer by the Board or the Compensation Committee, each of which gave consideration to each officer’s experience, expertise and performance, as well as market compensation levels for similar positions.

Name	​	​	Base Salary ($)(1)				​
Sushil Patel, Chief Executive Officer	​	​	​	​	700,000	​	​

​

The reported base salaries reflect payments actually received during our fiscal year ended March 31, 2026.

​

Annual Performance-Based Incentive Opportunity

In addition to base salaries, our named executive officers are eligible to receive annual performance-based cash incentives, which are designed to motivate our executives to achieve defined annual corporate goals and to reward our executives for their contributions towards the achievement of these goals. The annual performance-based incentive that each named executive officer was eligible to receive in respect of services performed during the fiscal year ended March 31, 2026 was determined at the discretion of the Board and Compensation Committee based in part on the extent to which the named executive officer achieved the corporate goals and individual objectives that our Board established at the beginning of the fiscal year. After the end of the fiscal year ended March 31, 2026, our Board reviewed performance against each goal and objective and determined the extent to which each goal and objective was achieved.

For our fiscal year ended March 31, 2026, Dr. Patel, Ms. Hill and Dr. Xynos were eligible to receive a target bonus of up to 60%, 40% and 40% of their base salary, respectively. Our Board reviewed the corporate goals for the fiscal year ended March 31, 2026 and the individual objectives of each named executive officer and determined that on an overall basis, significant progress had been made towards achieving many of the target goals. In recognition of these achievements and the efforts of each of our named executive officers, the Compensation Committee awarded Dr. Patel, Ms. Hill and Dr. Xynos 75%, 92.5% and 92.5% of their target bonus opportunity, respectively, for the fiscal year ended March 31, 2026. Accordingly, for the fiscal year ended March 31, 2026, Dr. Patel, Ms. Hill and Dr. Xynos were paid bonuses of $315,000, $196,320, $198,320, respectively.

before June 30, 2026. On June 30, 2026, the Compensation Committee discussed the series of complete response letters (CRLs) issued by the Food and Drug Administration (FDA) in connection with the Company’s Biologics License Application (BLA) for RP1 (vusolimogene oderparepvec) in combination with nivolumab for the treatment of advanced melanoma, the Company’s on-going communications with the FDA and the FDA’s acceptance of the Company’s Class 1 BLA resubmission on June 2, 2026. Following such discussion, on June 30, 2026 the Compensation Committee agreed to extend the performance period with respect to the “Target” performance level set forth in the PSU Award Agreement to end on December 24, 2026. Accordingly, if approval is received by December 24, 2026, the PSUs will vest at 100%.

Pension Benefits

Our named executive officers did not participate in, or otherwise receive any benefits under, any pension or retirement plan during the fiscal year ended March 31, 2026, other than pursuant to the plans described under “401(k) Plan.”

Nonqualified Deferred Compensation

Our named executive officers did not participate in, or earn any benefits under, a nonqualified defined contribution or other nonqualified deferred compensation plan during the fiscal year ended March 31, 2026.

401(k) Plan

We offer a tax-qualified retirement plan that provides eligible U.S. employees with an opportunity to save for retirement on a tax advantaged basis. Eligible employees are able to defer eligible compensation up to certain statutory limits, which are updated annually. We provide matching contributions up to 50% of actual dollars contributed, not to exceed a maximum of 8% of gross salary. Employee contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participant’s directions. Employees are immediately and fully vested in their own and in our matching contributions. The 401(k) plan is intended to be qualified under Section 40 1(a) of the Internal Revenue Code, or the Code, with the related trust intended to be tax exempt under Section 50 1(a) of the Code. As a tax-qualified retirement plan, contributions to the 401(k) plan are deductible by us when made, and contributions and earnings on those amounts are not taxable to the employees until withdrawn or distributed from the 401(k) plan.

U.K. Pension Contribution Plan

We provide a “stakeholder” pension contribution plan for our employees in the United Kingdom, pursuant to which we match our employees’ contributions each year in amounts up to 8% of their annual base salary.

Employment Agreements

Set forth below are descriptions of the employment agreements that we have entered into with each of our named executive officers, including descriptions of our named executive officers’ base salary, target annual bonus opportunity and standard benefit plan participation.

Sushil Patel

In connection with Dr. Patel’s transition to the role of Chief Executive Officer, on April 1, 2024, Dr. Patel entered into a second amended and restated employment agreement (the “Patel Second A&R Agreement”) with Replimune, which amended and restated the previous amended and restated employment agreement, dated, May 3, 2021, between Replimune and Dr. Patel, as amended further as of December 30, 2022. Under the Patel Second A&R Agreement, Dr. Patel is entitled to an initial annual base salary of $600,000 and is eligible to receive an annual discretionary performance bonus based on a target percentage of annual base salary, which target percentage is initially 60%. Each of Dr. Patel’s annual base salary and discretionary bonus may be adjusted by the Compensation Committee. The Patel Second A&R Agreement also provides for customary terms of benefits afforded to Dr. Patel, including eligibility to participate in

28

TABLE OF CONTENTS

various group insurance plans (subject to the terms thereof), reimbursement for necessary and reasonable travel and other business expenses, and paid time off. Furthermore, Dr. Patel is eligible for grants under the Replimune Group, Inc. 2018 Omnibus Incentive Compensation Plan, as it may be amended from time to time, or any successor plan (the “2018 Plan”), but will have terms and conditions consistent with those set forth in the Plan, as determined by the Compensation Committee.

Consistent with Dr. Patel’s existing agreement, the Patel Second A&R Agreement further provides that in the event Dr. Patel’s employment is terminated by Replimune without “cause,” or by Dr. Patel for “good reason,” each, as defined in the Patel Second A&R Agreement, and subject to customary conditions, including Dr. Patel’s delivery of an effective separation agreement and general release, (a) Dr. Patel is entitled to receive an amount equal to Dr. Patel’s annual base salary, with payment made in installments over a 12-month period following the termination date in accordance with Replimune’s normal payroll practices, and (b) Replimune will pay on Dr. Patel’s behalf the COBRA premiums for continued health care coverage under its group health plans for Dr. Patel and Dr. Patel’s eligible dependents (“COBRA Payments”) for the period from the termination date until the earlier of (i) the end of the 12-month period following the termination date, (ii) the date Dr. Patel becomes eligible for group health insurance coverage through a subsequent employer, or (iii) the date Dr. Patel ceases to be eligible for COBRA coverage for any reason.

Additionally, consistent with Dr. Patel’s existing agreement, in the event that Dr. Patel’s employment is terminated by Replimune without “cause” or by Dr. Patel for “good reason” on or within 12 months following a “change of control,” as defined in the Patel Second A&R Agreement, provided that Dr. Patel delivers an effective separation agreement and general release, in lieu of the payments described in the preceding paragraph, (a) Dr. Patel is entitled to receive an amount equal to two times the sum of Dr. Patel’s annual base salary, plus Dr. Patel’s target annual discretionary bonus for the year of termination, with payment made in installments over the 24-month period following the termination date in accordance with the Replimune’s normal payroll practices, and (b) Replimune will pay on Dr. Patel’s behalf the COBRA Payments for the period from the termination date until the earlier of (i) the end of the 24-month period following the termination date, (ii) the date Dr. Patel becomes eligible for group health insurance coverage through a subsequent employer, or (iii) the date Dr. Patel ceases to be eligible for COBRA coverage for any reason.

Further, the Patel Second A&R Agreement provides that, in the event that Dr. Patel becomes entitled to receive payments that constitute “excess parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended, the aggregate present value of such payments will be reduced only if such reduction will provide Dr. Patel with a greater net after-tax benefit than would no reduction.

Pursuant to the Patel Second A&R Agreement, Dr. Patel is subject to customary non-competition and non-solicitation covenants during the term of Dr. Patel’s employment and for a period of one year thereafter. Dr. Patel is also subject to customary confidentiality restrictions.

Emily Hill

On August 31, 2023, Ms. Hill entered into an employment agreement with Replimune, Inc., with an effective date of September 18, 2023. Under Ms. Hill’s employment agreement, she is entitled to an initial base salary of $495,000 and is eligible to receive an annual discretionary target bonus based on a percentage of her base salary, which such percentage is initially 40%. Each of her salary and her discretionary bonus may be adjusted by the Compensation Committee. Ms. Hill’s employment agreement also provides for customary terms of benefits afforded to Ms. Hill, including the ability to participate in various group insurance plans, reimbursement for necessary and reasonable business expenses and paid time off. Furthermore, Ms. Hill may be eligible for grants that are outside of the Plan but will have terms and conditions consistent with those set forth in the Plan, as determined by the Compensation Committee.

Ms. Hill’s employment agreement further provides that in the event her employment is terminated without “cause,” or she terminates her employment for “good reason,” each, as defined in her employment agreement, and subject to customary conditions, including her execution of an acceptable release, Ms. Hill is entitled to receive (i) an amount equal to her annual base salary, with payment made in installments over a 12-month period following termination in accordance with the Company’s normal payroll practices, and (ii) a reimbursement on a monthly basis following the termination date for the COBRA premiums that she pays for continued health coverage under the Company’s health plan for herself and her dependents for the earlier

Under Dr. Xynos’ employment agreement, he is entitled to an initial base salary of $480,000 and is eligible to receive an annual discretionary target performance bonus based on a percentage of his base salary, which such percentage is initially 40%.

Compensation Consultant

In connection with our executive compensation review during the fiscal year ended March 31, 2026, our Compensation Committee continued to rely on Pearl Meyer to provide guidance with respect to the development and implementation of our compensation arrangements with our executive officers and other employees.

30

TABLE OF CONTENTS

Our Compensation Committee charter requires that the compensation consultant be independent of our management. During the fiscal year ended March 31, 2026, Pearl Meyer did not provide services to us other than the services described in this Proxy Statement. Our Compensation Committee has determined that Pearl Meyer is independent and that its work does not raise any conflict of interest.

TABLE OF CONTENTS​​

PAY VERSUS PERFORMANCE

The Company is a smaller reporting company, and its most recent fiscal year ended March 31, 2026. As required by Item 402(v) of Regulation S-K, we are providing the following information regarding the relationship between executive compensation and our financial performance for each of the last two completed fiscal years. In determining the “compensation actually paid” ​(“CAP”) to our NEOs, we are required to make various adjustments to amounts that have been previously reported in the Summary Compensation Table in previous years, as the SEC’s valuation methods for this section differ from those required in the Summary Compensation Table. The “Executive Compensation” section of this proxy filing describes the compensation setting process for our executive officers, which is done independently from the disclosure requirements.

Pay Versus Performance Table

The following table provides the information required for our NEOs for each of the fiscal years ended March 31, 2026, March 31, 2025 and March 31, 2024, along with the financial information required for each fiscal year. As a pre-commercial biotechnology company, we do not use Net Income (Loss) performance in determining our executive compensation, and as a Smaller Reporting Company, we are not required to choose a “Company Selected Measure.”

The following summarizes the valuation assumptions used for stock option awards included as part of Compensation Actually Paid:

​

•

Expected life of each stock option is based on the “simplified method” using an average of the remaining vest and remaining term, as of the vest/FYE date.

​

•

Strike price is based on each grant date closing price and asset price is based on each vest/FYE closing price.

​

•

Risk free rate is based on the Treasury Constant Maturity rate closest to the remaining expected life as of the vest/FYE date.

​

•

Historical volatility is based on daily price history for each expected life (years) prior to each vest/​FYE date. Closing prices provided by S&P Capital IQ are adjusted for dividends and splits.

​

•

Represents annual dividend yield on each vest/FYE date.

AUDIT COMMITTEE REPORT

The report of the Audit Committee is not “soliciting material,” is not deemed “filed” with the SEC and is not to be incorporated by reference into any filing of the Company under the Securities Act of 1933 or the Securities Exchange Act of 1934, both as amended.

The Audit Committee has reviewed Replimune’s audited consolidated financial statements for the fiscal year ended March 31, 2026, and has discussed these statements with management and PricewaterhouseCoopers LLP, or PwC, Replimune’s independent registered public accounting firm. Replimune’s management team is responsible for the preparation of Replimune’s financial statements and for maintaining an adequate system of disclosure controls and procedures and internal control over financial reporting for that purpose. The independent registered public accounting firm audits the annual consolidated financial statements prepared by management, expresses an opinion as to whether those consolidated financial statements present fairly the consolidated financial position, results of operations and cash flows of Replimune in conformity with U.S. generally accepted accounting principles and discusses any issues they believe should be raised with the Audit Committee. The Audit Committee is responsible for providing independent, objective oversight of Replimune’s accounting functions and internal controls.

The Audit Committee also received from, and discussed with, PwC the written disclosures and other communications that Replimune’s independent registered public accounting firm is required to provide to the Audit Committee, including the matters required to be discussed by Statement on Auditing Standards No. 1301, as amended (Communications with Audit Committees), as adopted by the Public Company Accounting Oversight Board, or PCAOB, in Rule 3200T.

PwC also provided the Audit Committee with the written disclosures and the letter required by the PCAOB requiring independent registered public accounting firms to annually disclose in writing all relationships that, in their professional opinion, may reasonably be thought to bear on independence, to confirm their perceived independence and to engage in a discussion of independence. The Audit Committee has reviewed this disclosure and has discussed with PwC their independence from Replimune.

Based on its discussions with management and Replimune’s independent registered public accounting firm as outlined above, and its review of the representations and information provided by management and Replimune’s independent registered public accounting firm, the Audit Committee recommended to the Board that the audited consolidated financial statements be included in Replimune’s Annual Report on Form 10-K for the year ended March 31, 2026, for filing with the Securities and Exchange Commission.

PROPOSAL NO. 1 — RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

We are asking our stockholders to ratify the Audit Committee’s selection of PricewaterhouseCoopers LLP, or PwC, as our independent registered public accounting firm for the fiscal year ending March 31, 2027. PwC has served as our independent registered public accounting firm since 2018.

The Audit Committee annually reviews the independent registered public accounting firm’s independence, including reviewing all relationships between the independent registered public accounting firm and us and any disclosed relationships or services that may impact the objectivity and independence of the independent registered public accounting firm, and the independent registered public accounting firm’s performance.

Although stockholder ratification is not required by our bylaws or otherwise, the Board believes it is advisable to provide stockholders an opportunity to ratify this selection and is submitting the selection of PwC as our independent registered public accounting firm to our stockholders for ratification as a matter of good corporate practice. If the selection is not ratified, the Audit Committee will consider whether it is appropriate to select another independent registered public accounting firm, but is not required to do so. Even if the selection is ratified, the Audit Committee in its discretion may select a different registered public accounting firm at any time during the year if the Audit Committee determines that such a change would be in the best interests of Replimune and its stockholders.

We expect that a representative of PwC will virtually attend the Annual Meeting and will have an opportunity to make a statement if he or she so chooses and will be available to respond to appropriate questions from stockholders in accordance with the Annual Meeting’s Rules of Conduct.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm

The Audit Committee pre-approves all auditing services, and permitted non-audit services (including the fees and terms thereof) to be performed by PwC, subject to the de minimis exception for non-audit services that are approved by the Audit Committee prior to the completion of an audit. The Audit Committee may delegate pre-approval authority to one or more members of the Audit Committee consistent with applicable law, Nasdaq listing standards and SEC rules and regulations, provided that the decisions of such Audit Committee member or members must be presented to the full Audit Committee at its next scheduled meeting.

Principal Accountant Fees and Services

We regularly review the services and fees of our independent accountants. These services and fees are also reviewed by the Audit Committee on an annual basis. The approximate aggregate fees billed for the fiscal years ended March 31, 2025 and 2026 for each of the following categories of services are as follows:

The Audit Committee has pre-approved all services performed since the pre-approval policy was adopted.

The affirmative vote of a majority of shares of our common stock present or represented by proxy at the Annual Meeting and entitled to vote is required to ratify the selection of our independent registered public accounting firm. An abstention is treated as present and entitled to vote and, therefore, has the effect of a vote “against” the ratification of the selection of our independent registered public accounting firm. Because the ratification of the selection of our independent registered public accounting firm is a routine matter, a nominee holding shares in street name may vote on this proposal in the absence of instructions from the beneficial owner.

PROPOSAL NO. 2 — APPROVAL, ON A NON-BINDING ADVISORY BASIS, OF THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS

In accordance with the rules of the SEC, we are providing stockholders with an opportunity to make a non-binding advisory vote on the compensation of the Company’s named executive officers for the fiscal year ended March 31, 2026. This non-binding advisory vote is commonly referred to as a “say on pay” vote and gives our stockholders the opportunity to express their views on our named executive officers’ compensation as a whole. This vote is not intended to address any specific item of compensation or any specific named executive officer, but rather the overall compensation of all of our named executive officers and the philosophy, policies, and practices described in this Proxy Statement. We currently hold say on pay votes annually, and we will hold our next say on pay vote at the 2027 Annual Meeting of Stockholders.

Stockholders are urged to read the section titled “Executive Compensation,” which discusses how our executive compensation policies and procedures implement our compensation philosophy and contains tabular information and narrative discussion about the compensation of our named executive officers. We believe that our compensation policies and decisions are focused on pay-for-performance principles and strongly aligned with our stockholders’ interests. Compensation of our named executive officers is designed to enable us to attract and retain talented and experienced executives, whose knowledge, skills and performance are critical to our success, and motivate these executive officers to achieve our business objectives and to lead us in a competitive environment. We are asking our stockholders to indicate their support for the compensation of our named executive officers as described in this Proxy Statement by casting a non-binding advisory vote “FOR” the following resolution:

“RESOLVED, that the stockholders hereby approve, on a non-binding advisory basis, the compensation of the “named executive officers” of Replimune Group, Inc. for the fiscal year ended March 31, 2026, as disclosed in the section titled “Executive Compensation” in the proxy statement for the Replimune Group, Inc. 2026 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the SEC, including the compensation tables and narrative discussion.”

As an advisory vote, this Say on Pay Proposal is not binding. Neither the outcome of this advisory vote nor of the advisory vote included in this Say on Pay Proposal overrules any decision by the Company or our Board (or any committee thereof), creates or implies any change to the fiduciary duties of the Company or our Board (or any committee thereof), or creates or implies any additional fiduciary duties for the Company or our Board (or any committee thereof). 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 Say on Pay Proposal and will consider the outcome of the vote when making future compensation decisions for our named executive officers.

The affirmative vote of a majority of shares of our common stock present or represented by proxy at the Annual Meeting and entitled to vote is required to approve, on a non-binding advisory basis, the compensation of the Company’s named executive officers for the fiscal year ended March 31, 2026. An abstention is treated as present and entitled to vote and, therefore, has the effect of a vote “against” this proposal. Broker non-votes will not be treated as votes cast for this purpose and, therefore, will not affect the outcome of the vote.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE NON-BINDING ADVISORY APPROVAL OF THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS.

PROPOSAL NO. 3 — APPROVAL OF AN AMENDMENT TO THE THIRD AMENDED AND RESTATED CERTIFICATE OF INCORPORATION OF THE COMPANY TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK, PAR VALUE $0.001 PER SHARE, FROM 150,000,000 SHARES TO 300,000,000 SHARES

Summary

We are asking our stockholders to approve an amendment to Article Four, Section 1(a) of our Third Amended and Restated Certificate of Incorporation to increase the total number of authorized shares of common stock, par value $0.001 per share, from 150,000,000 shares to 300,000,000 shares (the “Charter Amendment”). The Charter Amendment will not change the number of authorized shares of preferred stock, which will remain at 10,000,000 shares. If approved, the total number of shares of all classes of capital stock that the Company is authorized to issue will increase from 160,000,000 shares to 310,000,000 shares.

Current Utilization of Authorized Shares

The following table sets forth, as of March 31, 2026, information regarding our authorized, issued and outstanding, reserved, and available shares of common stock:

​	​	​	Shares				​
Authorized shares of common stock	​	​	​	​	150,000,000	​	​
Shares of common stock issued and outstanding	​	​	​	​	82,716,923	​	​
Shares issuable upon exercise of outstanding stock options, having a weighted average exercise price of $14.12 per share	​	​	​	​	11,785,458	​	​
Shares issuable upon vesting and settlement of outstanding restricted stock units and performance stock units	​	​	​	​	5,508,882	​	​
Shares reserved for future issuance under our 2018 Omnibus Incentive Compensation Plan	​	​	​	​	1,569,457	​	​
Shares reserved for future issuance under our Employee Stock Purchase Plan	​	​	​	​	4,102,399	​	​
Pre-IPO warrants to purchase common stock	​	​	​	​	—	​	​
Shares issuable upon exercise of pre-funded warrants	​	​	​	​	14,058,153	​	​
Total shares issued, outstanding, and reserved	​	​	​	​	119,741,272	​	​
Authorized shares of common stock available for future issuance	​	​	​	​	30,258,728	​	​

As of March 31, 2026, 30,258,728 shares of authorized common stock remained available for future issuance. The Charter Amendment will not change the number of authorized shares of preferred stock. As of March 31, 2026, 10,000,000 shares of undesignated preferred stock, par value $0.001 per share, were authorized, and no undesignated shares of preferred stock were issued and outstanding.

Reasons for the Charter Amendment

In July 2026, the Board determined that the Charter Amendment was advisable and in the best interests of the Company and its stockholders and unanimously approved the Charter Amendment, subject to stockholder approval.

The Board believes that additional authorized shares of common stock are necessary to provide the Company with the flexibility to respond to future opportunities and needs. In particular, the Board considered the following factors in recommending the Charter Amendment:

•

Future capital-raising or financing transactions.   The Company’s product candidates are in various stages of clinical and preclinical development, and the Company may need to raise additional capital in the future through public or private offerings of common stock or securities convertible into or exchangeable for common stock. Maintaining a sufficient reserve of authorized shares allows the Company to pursue such transactions on a timely basis and potentially on favorable terms.

​

•

Strategic transactions.   The additional authorized shares of common stock would provide the Company with the flexibility to pursue potential strategic transactions, including mergers, acquisitions,

​

39

TABLE OF CONTENTS

collaborations, licensing arrangements, and other business combinations, potentially using shares of common stock as consideration.

•

Pipeline development.   The Company’s long-term growth strategy is driven by the continued development, commercialization, and advancement of its pipeline of product candidates, which may require significant capital investment. The proceeds of future equity offerings are expected to support the Company’s development of its product candidates and execution of its long-term growth strategy.

​

•

Equity compensation.   The Company operates in a highly competitive market for talent in the biotechnology industry. The ability to grant equity awards under the Company’s equity compensation plans is critical to attracting and retaining qualified employees, officers, and directors.

​

The Board currently has no specific plans, arrangements, or agreements to issue any of the proposed additional authorized shares of common stock, other than (i) shares that may be issued under the Company’s existing equity compensation plans in the ordinary course, (ii) potential issuances pursuant to a sales Agreement the Company entered into on August 3, 2023, as amended, with Leerink Partners LLC, through which the Company may offer and sell shares of its common stock from time to time in “at-the-market” offerings, and (iii) future issuances of additional shares or other equity or debt securities exercisable for, or convertible into, shares of the Company’s common stock. As a general matter, the Board would be able to issue the additional authorized shares at its discretion from time to time without further action or approval of the Company’s stockholders, except as may be required by applicable law or the rules and listing requirements of Nasdaq or any other applicable securities exchange. For example, Nasdaq listing rules generally require stockholder approval for issuances of common stock in connection with certain acquisitions, private placements, or equity compensation arrangements that exceed specified thresholds.

Effects of the Charter Amendment

If the Charter Amendment is approved, the additional 150,000,000 authorized shares of common stock will be identical in all respects to the shares of common stock currently authorized and outstanding. Holders of our common stock do not currently have, and will not have as a result of the Charter Amendment, preemptive, subscription, redemption, or conversion rights. The Charter Amendment will not change the number of shares of common stock or preferred stock currently outstanding, nor will it have any immediate dilutive effect or change the rights of current holders of our common stock.

However, to the extent that the additional authorized shares of common stock are issued in the future, such issuance may decrease existing stockholders’ respective percentage of equity ownership in the Company and could be dilutive to the voting power of existing stockholders, and depending on the price at which they are issued, such shares may dilute earnings and book value on a per share basis. Because our stockholders do not have preemptive rights, current stockholders would not have a prior right to purchase any new issuance of capital stock in order to maintain their proportionate ownership of our common stock.

Anti-Takeover Considerations

The availability of additional shares of common stock for issuance could, under certain circumstances, discourage or make any efforts to obtain control of the Company more difficult. For example, the Board could, without further stockholder approval, issue shares of common stock in a public or private offering, including to persons allied with the Board, which could dilute the stock ownership or voting power of parties seeking to obtain control of the Company. The increase in authorized shares of common stock could also have the effect of rendering more difficult or discouraging a merger, tender offer, or proxy contest, the assumption of control by a holder of a large block of our stock, or the removal of incumbent management. The Board is not aware of any actual or contemplated attempt to acquire control of the Company, and the Charter Amendment is not being presented with the intent that it be used to prevent or discourage any acquisition attempt. Notwithstanding the foregoing, the Board remains committed to taking any actions that it deems consistent with its fiduciary duties.

No Appraisal Rights

Stockholders will not have any appraisal or dissenters’ rights under the Delaware General Corporation Law in connection with the Charter Amendment.

40

TABLE OF CONTENTS

Text of the Charter Amendment

If the Charter Amendment is approved by our stockholders, Article Four, Section 1(a) of our Third Amended and Restated Certificate of Incorporation would be amended and restated in its entirety to read as follows:

Section 1.   Authorized Shares.   The total number of shares of all classes of capital stock which the Corporation shall have authority to issue is 310,000,000 shares, consisting of:

(a)

Three Hundred Million (300,000,000) shares of common stock, par value $0.001 per share (“Common Stock”); and

​

(b)

Ten Million (10,000,000) shares of undesignated preferred stock, par value $0.001 per share (the “Preferred Stock”)

​

The full text of the proposed Certificate of Amendment is attached to this Proxy Statement as Appendix A.

Timing of the Charter Amendment; Right to Abandon

If the Charter Amendment is approved by our stockholders, the amendment will become effective immediately upon the filing of a Certificate of Amendment to our Third Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, which we expect to file promptly after the Annual Meeting. Notwithstanding stockholder approval of the Charter Amendment, at any time prior to the effectiveness of the filing of the Certificate of Amendment with the Secretary of State of the State of Delaware, the Board may abandon the Charter Amendment without further action by the stockholders. If the Charter Amendment is not approved by our stockholders, the number of authorized shares of common stock will remain unchanged at 150,000,000.

Risks of Non-Approval

If our stockholders do not approve the Charter Amendment, our authorized shares of common stock will remain at 150,000,000 shares, of which only 30,258,728 shares remained available for future issuance as of March 31, 2026. The Company’s long-term growth strategy may require the issuance of additional shares beyond those currently available. Without sufficient authorized shares, the Company could face the following risks:

•

The Board may be unable to pursue capital-raising transactions, strategic acquisitions, or other corporate opportunities on a timely basis, potentially causing the Company to miss time-sensitive opportunities that could be in the best interests of the Company and its stockholders.

​

•

The Company may face substantial challenges in hiring and retaining employees at all levels, including members of its executive leadership team, if sufficient shares are not available for equity compensation awards.

​

•

The Company may be required to seek stockholder approval on a transaction-by-transaction basis before issuing shares, which could result in significant delays and additional costs.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE CHARTER AMENDMENT.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Related Party Transactions Policy

Our Board has adopted a formal written policy that our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of any class of our common stock and any members of the immediate family of any of the foregoing persons are not permitted to enter into a related person transaction with us without the prior review and ratification of the Audit Committee. Any request for us to enter into a transaction with an executive officer, director, nominee for election as a director, beneficial owner of more than 5% of any class of our common stock or any member of the immediate family of any of the foregoing persons in which the amount involved exceeds $120,000 and such person would have a direct or indirect material interest must first be presented to the Audit Committee for review, consideration and approval. In approving or rejecting any such proposal, the Audit Committee is to consider the material facts of the transaction, including, but not limited to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction.

Other than as disclosed below, during the fiscal year ended March 31, 2026, we were not a party to any transactions or series of similar transactions, in which:

•

the amounts involved exceeded or will exceed $120,000; and

​

•

any of the directors, executive officers or holders of more than 5% of our voting equity, or any member of the immediate family of the foregoing persons, had or will have a direct or indirect material interest.

​

Compensation arrangements for our directors and named executive officers are described elsewhere in this Proxy Statement.

Stockholders Sharing an Address / Householding

The SEC has adopted rules that permit companies and intermediaries (such as banks and brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

Only one copy of our Annual Report on Form 10-K for the fiscal year ended March 31, 2026 and this Proxy Statement is being delivered to multiple stockholders sharing an address, unless we have received contrary instructions from one or more of the stockholders.

We will undertake to deliver promptly, upon written or oral request, a separate copy to a stockholder at a shared address to which a single copy of the Annual Report on Form 10-K for the fiscal year ended March 31, 2026 and this Proxy Statement was delivered. To receive a separate copy of our Annual Report on Form 10-K for the fiscal year ended March 31, 2026 or this Proxy Statement, or to receive separate copies in the future, or if two stockholders sharing an address have received two copies of any of these documents and desire to only receive one, you may write to Investor Relations at Replimune Group, Inc. at our principal executive offices at 500 Unicorn Park Drive, Suite 303, Woburn, MA 01801 or call Investor Relations at +1 (339) 970-2843.
