NOTICE OF 2023 ANNUAL MEETING OF STOCKHOLDERS

To Be Held on June 21, 2023

Dear Stockholders:

You are cordially invited to virtually attend the 2023 annual meeting of stockholders, or the Annual Meeting, of Werewolf Therapeutics, Inc. The Annual Meeting will be held via the Internet at a virtual web conference at www.virtualshareholdermeeting.com/HOWL2023 on Wednesday, June 21, 2023, at 9:00 a.m., Eastern time.

Only stockholders who owned shares of our common stock at the close of business on April 24, 2023, can vote at the Annual Meeting or any adjournment thereof. At the Annual Meeting, the stockholders will consider and vote on the following matters:

1.	Election of three Class II directors nominated by our board of directors, each to serve for a three-year term expiring at the 2026 annual meeting of stockholders;

2.	Ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023; and

3.	Transaction of any other business that may properly come before the Annual Meeting or any adjournment or postponement thereof.

As noted above, our Annual Meeting will be a “virtual meeting” of stockholders, which will be conducted exclusively via the Internet at a virtual web conference. There will not be a physical meeting location, and stockholders will not be able to attend the Annual Meeting in person. This means that you can attend the Annual Meeting online, vote your shares and submit questions during the online meeting. We believe that hosting a “virtual meeting” will enable greater stockholder attendance and participation from any location around the world.

You can find more information, including the nominees for director, in the attached proxy statement for the Annual Meeting. The board of directors recommends that you vote “FOR” each of the Class II directors (Proposal 1) and “FOR” the ratification of the appointment of the proposed independent registered public accounting firm (Proposal 2) as outlined in the attached proxy statement.

We are pleased to comply with the rules of the Securities and Exchange Commission that allow companies to distribute their proxy materials over the Internet under the “notice and access” approach. As a result, we are sending to our stockholders a Notice of Internet Availability of Proxy Materials, or the Notice of Availability, instead of a paper copy of this proxy statement and our annual report for the fiscal year ended December 31, 2022, or the 2022 Annual Report. We will mail the Notice of Availability on or about April 27, 2023, and the Notice of Availability contains instructions on how to access our proxy materials over the Internet. The Notice of Availability also contains instructions on how each of our stockholders can receive a paper copy of our proxy materials, including the proxy statement, our 2022 Annual Report, and a form of proxy card.

Stockholders of record at the close of business on April 24, 2023, the record date for the Annual Meeting, are entitled to notice of, and to vote at, the Annual Meeting or any adjournment or postponement thereof.

Whether or not you expect to virtually attend the Annual Meeting online, please vote your shares to ensure your representation and the presence of a quorum at the Annual Meeting.

A complete list of registered stockholders will be available at least ten days prior to the meeting for inspection at our offices at 200 Talcott Ave, 2nd Floor, Watertown, Massachusetts 02472. This list will also be available to

IMPORTANT INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

Purpose of the Annual Meeting

Our board of directors unanimously recommends that you vote:

FOR the election of the three nominees to serve as Class II directors on our board of directors, each for a three-year term expiring at the 2026 annual meeting of stockholders; and

FOR the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023.

Availability of Proxy Materials

The proxy materials, including this proxy statement, a proxy card and our 2022 Annual Report are available for viewing, printing and downloading on the Internet at www.proxyvote.com. On or about April 27, 2023, we will mail the Notice of Availability to stockholders, unless they requested a printed copy of proxy materials. If you would like to receive a paper copy of our proxy materials, you should follow the instructions for requesting paper materials in the Notice of Availability.

Who Can Vote at the Annual Meeting?

Only stockholders of record at the close of business on the record date of April 24, 2023 are entitled to receive notice of the Annual Meeting and to vote the shares of our common stock that they held on that date. As of April 24, 2023, there were 35,519,801 shares of our common stock issued and outstanding. Each share of common stock is entitled to one vote on each matter properly brought before the Annual Meeting.

Difference Between a “Stockholder of Record” and a Beneficial Owner of Shares Held in “Street Name”

Stockholder of Record. If your shares are registered directly in your name with our transfer agent, Computershare Trust Company, then you are considered the “stockholder of record” of those shares. In this case, your Notice of Availability has been sent to you directly by us. You may vote your shares by proxy prior to the Annual Meeting by following the instructions contained in the Notice of Availability and in the section titled “How to Vote” below.

Beneficial Owner of Shares Held in Street Name. If your shares are held by a bank, broker or other nominee, then you are considered the beneficial owner of those shares, which are held in “street name.” In this case, your Notice of Availability will be sent to you by that organization. The organization holding your shares is considered the stockholder of record for purposes of voting at the Annual Meeting.

As the beneficial owner, you have the right to instruct that organization as to how to vote the shares held in your account by following the instructions contained on the voting instruction card provided to you by that organization.

TABLE OF CONTENTS

Why is the Annual Meeting a Virtual, Online Meeting?

We believe that hosting a virtual meeting will facilitate stockholder attendance and participation at our Annual Meeting by enabling stockholders to safely participate from any location around the world. Our virtual meeting will be governed by our Rules of Conduct and Procedures which will be posted at www.virtualshareholdermeeting.com/HOWL2023 in advance of the meeting. We have designed the virtual annual meeting to provide the same rights and opportunities to participate as stockholders would have at an in-person meeting, including the right to vote and ask questions through the virtual meeting platform.

How to Virtually Attend the Annual Meeting

The Annual Meeting will be a virtual meeting and you may not attend in person. The Annual Meeting will start at 9:00 a.m., Eastern time, on June 21, 2023. You may log on to the virtual meeting starting at 8:45 a.m., Eastern time, on the day of the meeting. If you encounter any difficulties accessing the virtual Annual Meeting, please call the technical support number that will be posted on the log-in page at www.virtualshareholdermeeting.com/HOWL2023.

How to Vote

If you are the stockholder of record of your shares, you can vote your shares by proxy prior to the Annual Meeting or online during the Annual Meeting. If you choose to vote by proxy prior to the Annual Meeting, you may do so by telephone, via the Internet or by mail as follows:

•	By Telephone Prior to the Annual Meeting. You may transmit your proxy over the phone by calling 1-800-690- 6903 and following the instructions provided in the Notice of Availability and on the proxy card. You will need to have your Notice of Availability or proxy card in hand when you call.

•

Via the Internet Prior to the Annual Meeting. You may transmit your proxy via the Internet by following the instructions provided in the Notice of Availability and on the proxy card. You will need to have your Notice of Availability or proxy card in hand when you access the website. The website for voting is available at www.proxyvote.com.

•	By Mail Prior to the Annual Meeting. If you requested printed copies of proxy materials, you can vote by mailing your proxy card as described in the proxy materials.

•

Online during the Annual Meeting. You may vote your shares online while virtually attending the Annual Meeting by following the instructions found on your Notice of Availability, proxy card and/or voting instruction form. If you vote by proxy prior to the Annual Meeting and choose to attend the Annual Meeting online, there is no need to vote again during the Annual Meeting unless you wish to change your vote.

Telephone and Internet voting for stockholders of record will be available until 11:59 p.m., Eastern time on June 20, 2023, and mailed proxy cards must be received June 20, 2023 in order to be counted at the Annual Meeting. If the Annual Meeting is adjourned or postponed, these deadlines may be extended.

If your shares are held in street name, your bank, broker or other nominee is required to vote the shares it holds on your behalf according to your instructions. The proxy materials, as well as voting and revocation instructions, should have been forwarded to you by the bank, broker or other nominee that holds your shares. In order to vote your shares you will need to follow the instructions that your bank, broker or other nominee provides you. The voting deadlines and availability of telephone and Internet voting for beneficial owners of shares held in “street name” will depend on the voting processes of the bank, broker or other nominee that holds your shares. Therefore, we urge you to carefully review and follow the voting instruction card and any other materials that you receive from that organization. In addition, you will need your control number included on your Notice of Availability, proxy card or voting instruction form in order to demonstrate proof of beneficial ownership and to be able to vote during the Annual Meeting.

Even if you plan to attend the Annual Meeting online, we urge you to vote your shares by proxy in advance of the Annual Meeting so that if you should become unable to attend the Annual Meeting your shares will be voted as directed by you.

TABLE OF CONTENTS

Can I Vote My Shares by Filling Out and Returning the Notice of Internet Availability of Proxy Materials?

No. The Notice of Availability and proxy card contain instructions on how to vote by proxy via the Internet, by telephone, by requesting and returning a paper proxy card, or by voting online while virtually attending the Annual Meeting.

How Do I Submit a Question at the Annual Meeting?

If you wish to submit a question during the Annual Meeting, beginning at 8:45 a.m., Eastern time, on June 21, 2023, you may log into www.virtualshareholdermeeting.com/HOWL2023, type your question into the “Submit a Question” field, and click “Submit.” Our virtual meeting will be governed by our Rules of Conduct and Procedures which will be posted at www.virtualshareholdermeeting.com/HOWL2023 in advance of the Annual Meeting. The Rules of Conduct and Procedures will address the ability of stockholders to ask questions during the meeting, including rules on permissible topics, and rules for how questions and comments will be recognized and disclosed to meeting participants.

May I See a List of Stockholders Entitled to Vote as of the Record Date?

A complete list of registered stockholders as of the close of business on the record date will be available at least ten days prior to the meeting for inspection by our stockholders of record at our offices at 200 Talcott Ave, 2nd Floor, Watertown, Massachusetts 02472. If you are unable to inspect this list in person, please contact our Corporate Secretary by mail at Werewolf Therapeutics, Inc., 200 Talcott Ave, 2nd Floor, Watertown, Massachusetts 02472, Attention: Corporate Secretary, or by email at legal@werewolftx.com to request such list. When making such request, please ensure that you have your Notice of Availability or proxy card available so that you can prove that you are a registered stockholder. Such list will also be available for examination by the stockholders during the Annual Meeting at www.virtualshareholdermeeting.com/HOWL2023.

Quorum

A quorum of stockholders is necessary to hold a valid meeting. Our amended and restated bylaws provide that a quorum will exist if stockholders holding a majority of the shares of stock issued and outstanding and entitled to vote at the meeting are present at the meeting in person or by proxy. Shares present virtually during the Annual Meeting will be considered shares of common stock represented in person at the meeting. If a quorum is not present, we expect to adjourn the Annual Meeting until a quorum is obtained.

Abstentions and broker non-votes count as present for establishing a quorum but will not be counted as votes cast. Broker non-votes occur when your bank, broker or other nominee submits a proxy for your shares (because the bank, broker or other nominee has received instructions from you on one or more proposals, but not all proposals, or has not received instructions from you but is entitled to vote on a particular “discretionary” matter) but does not indicate a vote for a particular proposal because the bank, broker or other nominee either does not have the authority to vote on that proposal and has not received voting instructions from you or has discretionary authority but chooses not to exercise it.

Proposals Considered “Discretionary” and “Non-Discretionary”

We expect the election of directors (Proposal No. 1) to be a non-discretionary matter. A bank, broker or other nominee cannot vote without instructions on non-discretionary matters, and therefore there may be broker non-votes on Proposal No. 1.

We expect the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023 (Proposal No. 2) to be a discretionary matter. A bank, broker or other nominee generally may exercise discretionary authority and vote on discretionary matters. If they exercise this discretionary authority, no broker non-votes are expected in connection with Proposal No. 2.

Votes Required to Elect a Director and to Ratify Appointment of Ernst & Young LLP

A nominee will be elected as a director if the nominee receives a plurality of the votes cast by stockholders entitled to vote at the meeting (Proposal No. 1).

TABLE OF CONTENTS

The ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023 requires the affirmative vote of a majority of the shares of common stock present or represented by proxy and voted “for” or “against” such matter (Proposal No. 2).

Abstentions and broker non-votes will not be counted as votes cast or voted on either of the proposals. Accordingly, abstentions and broker non-votes will have no effect on the voting on either of the proposals.

Method of Counting Votes

Each holder of common stock is entitled to one vote at the Annual Meeting on each matter to come before the Annual Meeting, including the election of directors, for each share held by such stockholder as of the record date. Votes cast online during the Annual Meeting or by proxy by mail, via the Internet or by telephone will be tabulated by the inspector of election appointed for the Annual Meeting, who will also determine whether a quorum is present.

Revoking a Proxy; Changing Your Vote

If you are a stockholder of record, you may revoke your proxy before the vote is taken at the Annual Meeting:

•	by submitting a new proxy with a later date before the applicable deadline either signed and returned by mail or transmitted using the telephone or Internet voting procedures described in the “How to Vote” section above;

•	by voting online at the Annual Meeting using the procedures described in the “How to Vote” section above; or

•	by filing a written revocation with our Corporate Secretary.

If your shares are held in “street name,” you may submit new voting instructions by contacting your bank, broker or other nominee holding your shares. You may also vote online during the Annual Meeting, which will have the effect of revoking any previously submitted voting instructions, if you obtain a legal proxy from the organization that holds your shares and follow the procedures described in the “How to Vote” section above.

Your virtual attendance at the Annual Meeting, without voting online during the Annual Meeting, will not automatically revoke your proxy.

Costs of Proxy Solicitation

We will bear the costs of soliciting proxies. Our directors, officers and regular employees, without additional remuneration, may solicit proxies by mail, telephone, facsimile, email, personal interviews and other means.

Voting Results

We plan to announce preliminary voting results at the Annual Meeting and will publish final results in a Current Report on Form 8-K to be filed with the SEC within four business days following the Annual Meeting.

TABLE OF CONTENTS

PROPOSAL NO. 1-ELECTION OF THREE CLASS II DIRECTORS

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

•	the Class II directors are Meeta Chatterjee, Ph.D., Derek DiRocco, Ph.D., and Daniel J. Hicklin, Ph.D., and their term expires at the Annual Meeting;

•	the Class III directors are Luke Evnin, Ph.D., and Alon Lazarus, Ph.D., and their term expires at the annual meeting of stockholders to be held in 2024; and

•	the Class I directors are Briggs Morrison, M.D., and Michael Sherman, MBA, and their term expires at the annual meeting of stockholders to be held in 2025.

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

Our restated certificate of incorporation provides that the authorized number of directors may be changed only by resolution of our board of directors. Our restated certificate of incorporation also provides that our directors may be removed only for cause and only by the affirmative vote of the holders of at least 75% of the votes that all our stockholders would be entitled to cast in an election of directors, and that any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office.

Our board of directors has nominated Meeta Chatterjee, Ph.D., Derek DiRocco, Ph.D., and Daniel J. Hicklin, Ph.D., for election as Class II directors at the Annual Meeting. Drs. Chatterjee, DiRocco and Hicklin are presently directors and have indicated a willingness to continue to serve as directors, if elected. If a nominee becomes unable or unwilling to serve, however, the proxies may be voted for substitute nominees selected by our board of directors.

We have no formal policy regarding board diversity, but our Corporate Governance Guidelines provide that the value of diversity should be considered and that the background and qualifications of the members of our board of directors considered as a group should provide a significant breadth of experience, knowledge, and abilities to assist our board of directors in fulfilling its responsibilities. Our priority in selection of board members is identification of members who will further the interests of our stockholders through their established records of professional accomplishment, the ability to contribute positively to the collaborative culture among our board members, knowledge of our business, understanding of the competitive landscape in which we operate and adherence to high ethical standards. Certain individual qualifications and skills of our directors that contribute to our board of directors’ effectiveness as a whole are described in the following paragraphs.

Nominees for Election as Class II Directors

Biographical information, including principal occupation and business experience during the last five years, and age as of April 27, 2023, for our nominees for election as the Class II directors at our Annual Meeting is set forth below.

Meeta Chatterjee, Ph.D., age 68, has served on our board of directors since October 2021. Dr. Chatterjee served as the Senior Vice President of Global Business Development at Legend Biotech Corporation from March 2019 until November 2022. From November 2007 to May 2018, she served in roles of increasing seniority and responsibility at Merck Research Laboratories, a division of Merck & Co., Inc., a multinational pharmaceutical company, most recently as Head of Strategy, Transactions, and Operations within the Business Development and Licensing (BD&L) group. Dr. Chatterjee has served on the board of directors of Editas Medicine, a publicly traded clinical stage biotechnology company, since December 2020. Dr. Chatterjee received her undergraduate education at St. Xavier’s University in Ahmedabad, India, and Rutgers University (B.A., Hons Physics). Dr. Chatterjee received her Doctor of Philosophy in Physiology from Rutgers University and completed a postdoctoral fellowship in the Department of Physiology at the University of Virginia School of Medicine. We believe Dr. Chatterjee’s thirty-plus years of broad strategic and operational experience in pharmaceutical research and development, mergers and acquisition evaluation, in-licensing, and externalization activities qualifies her to serve on our board of directors.

TABLE OF CONTENTS

Derek DiRocco, Ph.D., age 42, has served on our board of directors since December 2020. Dr. DiRocco has been a partner at RA Capital Management, L.P., since December 2020 and was previously a principal from December 2017 until December 2020, an analyst from June 2015 to December 2017, and an associate from July 2013 to June 2015. Dr. DiRocco has served on the board of directors of Acrivon Therapeutics, Inc. since November 2021, Connect Biopharma Holdings Limited since March 2021, iTeos Therapeutics, Inc. since March 2020, Mineralys Therapeutics, LLC since June 2022, and 89bio, Inc. since April 2018, each of which is a publicly traded biotechnology company. Dr. DiRocco previously served on the board of directors of Achilles Therapeutics plc from September 2019 to May 2022 and Day One Bio from February 2021 to May 2021. Dr. DiRocco also serves on the board of directors of several privately held biotechnology companies. Dr. DiRocco holds a B.A. in biology from College of the Holy Cross and a Ph.D. in pharmacology from the University of Washington. He conducted his postdoctoral research at Brigham and Women’s Hospital/Harvard Medical School. We believe that Dr. DiRocco is qualified to serve as a member of our board of directors because of his experience as an investor and director in multiple biotechnology companies.

Daniel J. Hicklin, Ph.D., age 60, has served on our board of directors since October 2017. Dr. Hicklin has also served as our President and Chief Executive Officer since August 2019. Dr. Hicklin founded Werewolf Therapeutics in October 2017 and served as a consultant until his appointment as our President and Chief Executive Officer. Dr. Hicklin also served as an Executive Partner at MPM Capital from 2014 to December 2019 and an advisor from January 2020 to December 2022. Previously, Dr. Hicklin was a founder of Potenza Therapeutics, Inc., a privately held biotechnology company, and served as its President and Chief Executive Officer from April 2014 until its acquisition by Astellas Pharma Inc. in December 2018. From August 2013 until February 2014, Dr. Hicklin was President and Chief Scientific Officer of CoStim Pharmaceuticals, Inc., a privately held biotechnology company that was acquired by Novartis in February 2014. Prior to joining CoStim Pharmaceuticals, Dr. Hicklin held several positions at Merck Research Laboratories (formerly the Schering-Plough Research Institute prior to its acquisition by Merck), including leading its Biologics Strategy for Oncology and the Immuno-Modulation Discovery team. Dr. Hicklin also previously held several positions at Imclone Systems Incorporated, including Vice President, Experimental Therapeutics. Dr. Hicklin has served as a member of the board of directors of several private biotechnology companies. Dr. Hicklin also currently serves on the Industry Advisory Committee for The Mark Foundation for Cancer Research. Dr. Hicklin holds an M.S. and Ph.D. in Microbiology and Immunology from New York Medical College, where he trained with Dr. Soldano Ferrone, and a B.S. from the University of Iowa. We believe that Dr. Hicklin’s operational and historical experience with our company gained from being a founder and serving as our President and Chief Executive Officer and member of our board of directors, combined with his extensive experience in oncology drug discovery, qualifies him to serve as a member of our board of directors.

The board of directors recommends voting “FOR” the election of Meeta Chatterjee, Ph.D., Derek DiRocco, Ph.D., and Daniel J. Hicklin, Ph.D., as Class II directors for a three-year term ending at the annual meeting of stockholders to be held in 2026.

Dr. Evnin holds an A.B. in molecular biology from Princeton University and a Ph.D. in biochemistry from the University of California, San Francisco.

Dr. Lazarus holds a Ph.D. in Molecular Biology from the Hadassah Medical School of Hebrew University of Jerusalem in Israel, an M.B.A. from the School of Business Administration of Hebrew University of Jerusalem in Israel and a B.Sc. in Biology from Hebrew University of Jerusalem in Israel.

PROPOSAL NO. 2-RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2023

Our stockholders are being asked to ratify the appointment by the audit committee of the board of directors of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023. Ernst & Young LLP has served as our independent registered public accounting firm since August 2022.

On August 31, 2022, our Audit Committee appointed Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022, subject to completion of Ernst & Young LLP’s customary client acceptance procedures. The decision to change auditors was the result of a request for proposal process in which we evaluated the credentials of several firms, including Deloitte & Touche LLP (“Deloitte”). On August 31, 2022, the Audit Committee also dismissed Deloitte as our independent registered public accounting firm. The audit report of Deloitte on our consolidated financial statements as of and for each of the two years in the period ended December 31, 2021 did not contain an adverse opinion or a disclaimer of an opinion, and were not qualified or modified as to uncertainty, audit scope, or accounting principles. During the fiscal years ended December 31, 2021 and 2020 and the subsequent interim period through August 31, 2022, there were no disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) with Deloitte on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Deloitte, would have caused Deloitte to make reference to the subject matter of the disagreements in its audit reports on our consolidated financial statements for such years. During the fiscal years ended December 31, 2021 and 2020 and in the subsequent interim period through August 31, 2022, there were no reportable events (as defined in Item 304(a)(1)(v) of Regulation S-K). During the fiscal years ended December 31, 2021 and 2020 and the subsequent interim period through August 31, 2022, neither we nor anyone on our behalf consulted with Ernst & Young LLP with respect to either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on our consolidated financial statements, and neither a written report nor oral advice was provided to us that Ernst & Young LLP concluded was an important factor considered by us in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) or a reportable event (as defined in Item 304(a)(1)(v) of Regulation S-K).

In connection with the filing of a Current Report on Form 8-K on September 7, 2022, we provided Deloitte with a copy of the disclosure included in the foregoing paragraph and requested that Deloitte furnish us with a letter addressed to the SEC stating whether or not it agreed with the statements made in the foregoing paragraph. A copy of Deloitte’s letter dated September 7, 2022 is attached as Exhibit 16.1 to the Current Report on Form 8-K that we filed on September 7, 2022.

The audit committee is solely responsible for selecting our independent registered public accounting firm for the fiscal year ending December 31, 2023. Stockholder approval is not required to appoint Ernst & Young LLP as our independent registered public accounting firm. However, the board of directors believes that submitting the appointment of Ernst & Young LLP to the stockholders for ratification is good corporate governance. If the stockholders do not ratify this appointment, the audit committee will reconsider whether to retain Ernst & Young LLP. If the selection of Ernst & Young LLP is ratified, the audit committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time it decides that such a change would be in the best interest of our company and our stockholders.

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

Our audit committee has adopted policies and procedures relating to the approval of all audit and non-audit services that are to be performed by our independent registered public accounting firm. This policy provides that we will not engage our independent registered public accounting firm to render audit or non-audit services unless the service is specifically approved in advance by our audit committee or the engagement is entered into pursuant to the pre-approval procedure described below.

From time to time, our audit committee may pre-approve specified types of services that are expected to be provided to us by our independent registered public accounting firm during the next fiscal quarter. Any such pre-approval is detailed as to the particular service or type of services to be provided and is also generally subject to a maximum dollar amount.

During our 2022 and 2021 fiscal years, no services were provided to us by Ernst & Young LLP or Deloitte & Touche LLP other than in accordance with the pre-approval policies and procedures described above.

The board of directors recommends voting “FOR” Proposal No. 2 to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023.

CORPORATE GOVERNANCE

Director Nomination Process

Our nominating and corporate governance committee is responsible for identifying individuals qualified to serve as directors, consistent with criteria approved by our board, and recommending the persons to be nominated for election as directors, except where we are legally required by contract, law or otherwise to provide third parties with the right to nominate director candidates.

The process followed by our nominating and corporate governance committee to identify and evaluate director candidates includes requests to board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by members of the committee and our board. While there are no specific minimum qualifications for a committee-recommended nominee to our board of directors, the qualifications, qualities and skills that our nominating and corporate governance committee believes must be met by a committee-recommended nominee for a position on our board of directors are as follows:

•	Nominees should have a reputation for integrity, honesty and adherence to high ethical standards.

•	Nominees should have demonstrated business acumen, experience and ability to exercise sound judgments in matters that relate to our current and long-term objectives and should be willing and able to contribute positively to our decision-making process.

•	Nominees should have a commitment to understand our company and our industry and to regularly attend and participate in meetings of our board of directors and its committees.

•	Nominees should have the interest and ability to understand the sometimes conflicting interests of our various constituencies, which include stockholders, employees, customers, governmental units, creditors and the general public, and to act in the interests of all stockholders.

•	Nominees should not have, nor appear to have, a conflict of interest that would impair the nominee’s ability to represent the interests of all of our stockholders and to fulfill the responsibilities of a director.

•	Nominees shall not be discriminated against on the basis of race, religion, national origin, sex, sexual orientation, disability or any other basis proscribed by law. The value of diversity on our board of directors should be considered.

The nominating and corporate governance committee may use a third-party search firm in those situations where particular qualifications are required or where existing contacts are not sufficient to identify an appropriate candidate.

Stockholders may recommend individuals to the nominating and corporate governance committee for consideration as potential director candidates. Any such proposals should be submitted to our Corporate Secretary at our principal executive offices and should include appropriate biographical and background material to allow the nominating and corporate governance committee to properly evaluate the potential director candidate and the number of shares of our stock beneficially owned by the stockholder proposing the candidate. The specific requirements for the information that is required to be provided for such recommendations to be considered are specified in our amended and restated bylaws and must be received by us no later than the date referenced below under the heading “Stockholder Proposals for our 2024 Annual Meeting.”

TABLE OF CONTENTS

Assuming that biographical and background material has been provided on a timely basis, any recommendations received from stockholders will be evaluated in the same manner as potential nominees proposed by the nominating and corporate governance committee. If our board of directors decides to nominate a stockholder-recommended candidate and recommends his or her election, then his or her name will be included on our proxy card for the next annual meeting.

Director Independence

The rules of the Nasdaq Stock Market, or Nasdaq, require a majority of a listed company’s board of directors to be comprised of independent directors within one year of listing. In addition, Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and compensation committee members must also satisfy the independence criteria set forth in Rule 10C-1 under the Exchange Act. Under applicable Nasdaq rules, a director will only qualify as an “independent director” if, in the opinion of the listed company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee, accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries or otherwise be an affiliated person of the listed company or any of its subsidiaries. In order to be considered independent for purposes of Rule 10C-1, the board must consider, for each member of a compensation committee of a listed company, all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: (1) the source of compensation of the director, including any consulting advisory or other compensatory fee paid by such company to the director; and (2) whether the director is affiliated with the company or any of its subsidiaries or affiliates.

In April 2023, our board of directors undertook a review of the composition of our board of directors and its committees and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our board of directors has determined that each of our current directors and director nominees, with the exception of Daniel J. Hicklin and Briggs W. Morrison, is an “independent director” as defined under applicable Nasdaq rules, including, in the case of all the members of our audit committee, the independence criteria set forth in Rule 10A-3 under the Exchange Act, and in the case of all the members of our compensation committee, the independence criteria set forth in Rule 10C-1 under the Exchange Act.

In making such determination, our board of directors considered the relationships that each such non-employee director has with our company and all other facts and circumstances that our board of directors deemed relevant

TABLE OF CONTENTS

in determining his or her independence, including the beneficial ownership of our capital stock by each non-employee director. Daniel J. Hicklin is not an independent director under these rules because he is our President and Chief Executive Officer. Briggs W. Morrison is not an independent as a result of certain payments made by Crossbow Therapeutics, Inc., or Crossbow, to us pursuant to the terms of a sublease agreement we entered into with Crossbow in May 2022 For further discussions about the sublease, please see “Certain Relationships and Related Person Transactions — Sublease Agreement.”

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

Board Committees

Our board of directors has established an audit committee, a compensation committee and a nominating and corporate governance committee, each of which operates under a charter approved by our board of directors. A current copy of the charter for each of the audit committee, compensation committee and the nominating and corporate governance committee is posted on the “Corporate Governance” section of the “Investors” section of our website, which is located at www.werewolftx.com. Our board of directors also appoints from time to time ad hoc committees to address specific matters.

Audit Committee

The members of our audit committee are Derek DiRocco, Ph.D., Alon Lazarus, Ph.D., and Michael Sherman, MBA, and Mr. Sherman is the chair of the audit committee. Our audit committee met eight times during 2022. Our audit committee’s responsibilities include:

•	appointing, approving the compensation of, and assessing the independence of our registered public accounting firm;

•	overseeing the work of our independent registered public accounting firm, including through the receipt and consideration of reports from such firm;

•	reviewing and discussing with management and our independent registered public accounting firm our annual and quarterly financial statements and related disclosures;

•	monitoring our internal control over financial reporting, disclosure controls and procedures and code of business conduct and ethics;

•	overseeing our risk assessment and risk management policies;

•	establishing policies regarding hiring employees from our independent registered public accounting firm and procedures for the receipt and retention of accounting-related complaints and concerns;

•	meeting independently with our internal auditing staff, if any, our independent registered public accounting firm and management; and

•	reviewing and approving or ratifying any related person transactions; and preparing the audit committee report required by SEC rules.

All audit and non-audit services, other than de minimis non-audit services, to be provided to us by our independent registered public accounting firm must be approved in advance by our audit committee.

Our board of directors has determined that Michael Sherman is an “audit committee financial expert” as defined by applicable SEC rules and that each of the members of our audit committee possesses the financial sophistication required for audit committee members under Nasdaq rules. We believe that the composition of our audit committee meets the requirements for independence under current Nasdaq and SEC rules and regulations.

TABLE OF CONTENTS

Compensation Committee

Throughout 2022, the members of our compensation committee were Luke Evnin, Ph.D., Alon Lazarus, Ph.D. and Briggs Morrison, M.D. In April 2023, the compensation committee was reconstituted and the current members of our compensation committee are Luke Evnin, Ph.D., and Alon Lazarus, Ph.D., and Dr. Lazarus is the chair of the compensation committee. Our compensation committee met five times during 2022. Our compensation committee’s responsibilities include:

•	reviewing and approving, or making recommendations to our board of directors with respect to, the compensation of our Chief Executive Officer and our other executive officers;

•	overseeing an evaluation of our senior executives;

•	overseeing and administering our cash and equity incentive plans;

•	reviewing and making recommendations to our board of directors with respect to director compensation;

•	reviewing and discussing annually with management our “Compensation Discussion and Analysis” disclosure if and to the extent required by SEC rules; and

•	preparing the compensation committee report if and to the extent then required by SEC rules.

We believe that the composition of our compensation committee meets the requirements for independence under current Nasdaq and SEC rules and regulations.

Nominating and Corporate Governance Committee

The members of our nominating and corporate governance committee are Meeta Chatterjee, Ph.D., Derek DiRocco, Ph.D., and Luke Evnin, Ph.D., and Dr. Evnin is the chair of the nominating and corporate governance committee. Our nominating and corporate governance committee met four times during 2022. Our nominating and corporate governance committee’s responsibilities include:

•	recommending to our board of directors the persons to be nominated for election as directors and to each of our board’s committees;

•	reviewing and making recommendations to our board of directors with respect to our board leadership structure;

•	reviewing and making recommendations to our board with respect to management succession planning;

•	developing and recommending to our board of directors corporate governance principles; and

•	overseeing an annual evaluation of our board of directors.

We believe that the composition of our nominating and corporate governance committee meets the requirements for independence under current Nasdaq and SEC rules and regulations.

Board of Director Meetings and Attendance

Our board of directors recognizes the importance of director attendance at board and committee meetings. The full board of directors met seven times during 2022. During 2022, each member of the board of directors attended in person or participated in 75% or more of the aggregate of (i) the total number of meetings held by the board of directors (during the period that such person served as a director) and (ii) the total number of meetings held by all committees of the board of directors on which such person served (during the periods that such person served).

Director Attendance at Annual Meeting of Stockholders

Our corporate governance guidelines provide that directors are responsible for attending the annual meeting of stockholders. All of our directors attended our annual meeting in 2022.

Code of Business Conduct and Ethics

We have adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer, or persons performing similar functions. A current copy of the code is posted on the “Corporate Governance”

TABLE OF CONTENTS

section of the “Investors” section of our website, which is located at http://www.werewolftx.com. If we make any substantive amendments to, or grant any waivers from, the code of business conduct and ethics for any officer or director, we will disclose the nature of such amendment or waiver on our website. We have included our website in this proxy statement solely as an inactive textual reference.

Corporate Governance Guidelines

Our board of directors has adopted corporate governance guidelines to assist the board of directors in the exercise of its duties and responsibilities and to serve the best interests of our company and our stockholders. These guidelines provide that:

•	the principal responsibility of our board of directors is to oversee our management;

•	a majority of the members of the board of directors must be independent directors, unless otherwise permitted by Nasdaq rules;

•	the independent directors meet in executive session at least twice a year;

•	directors have full and free access to management and, as necessary, independent advisors;

•	new directors participate in an orientation program and all directors are expected to participate in continuing director education on an ongoing basis; and

•	our nominating and corporate governance committee will oversee a periodic self-evaluation of the board to determine whether it and its committees are functioning effectively.

A copy of the corporate governance guidelines is available on the “Corporate Governance” section of the “Investors” section of our website, which is located at www.werewolftx.com.

Board Leadership Structure and Oversight of Risk

Our corporate governance guidelines provide that the nominating and corporate governance committee shall periodically assess the board of directors’ leadership structure, including whether the offices of chief executive officer and chair of the board of directors should be separate. Our guidelines provide the board of directors with flexibility to determine whether the two roles should be combined or separated based upon our needs and the board of directors’ assessment of its leadership from time to time. We do not currently have a lead independent director because the chair of our board of directors is independent within the meaning of the Nasdaq listing rules.

We currently separate the roles of chief executive officer and chair of the board of directors. Our president and chief executive officer is responsible for setting the strategic direction for our company and the day-to-day leadership and performance of our company, while the chair of our board of directors presides over meetings of the board of directors, including executive sessions of the board of directors, and performs oversight responsibilities. Separating the duties of the chair from the duties of the chief executive officer allows our chief executive officer to focus on our day-to-day business, while allowing the chair to lead the board of directors in its fundamental role of providing advice to and independent oversight of management.

Specifically, our chair runs meetings of our independent directors, facilitates communications between management and the board of directors and assists with other corporate governance matters. Our board of directors believes that this structure ensures a greater role for the independent directors in the oversight of our company and active participation of the independent directors in setting agendas and establishing priorities and procedures for the work of our board of directors. Our board of directors believes its administration of its risk oversight function has not affected its leadership structure. Our board of directors believes that we have an appropriate leadership structure for us at this time which demonstrates our commitment to good corporate governance. Although the roles of chair and chief executive officer are currently separate, our nominating and corporate governance committee and board of directors believe it is appropriate for our chief executive officer to serve as a member of our board of directors.

Risk is inherent with every business and how well a business manages risk can ultimately determine its success. We face a number of risks, including those described under “Risk Factors” in our Annual Report on Form 10-K. Our board of directors is actively involved in oversight of risks that could affect us. Our board of directors oversees our risk management processes directly and through its committees. Our management is responsible for risk management on a day-to-day basis and our board of directors and its committees oversee the risk

TABLE OF CONTENTS

management activities of management. Our board of directors satisfies this responsibility through full reports by each committee chair regarding the committee’s considerations and actions, as well as through regular reports directly from officers responsible for oversight of particular risks within our company. Our audit committee oversees risk management activities related to financial controls and legal and compliance risks. Our compensation committee oversees risk management activities relating to our compensation policies and practices and management succession planning. Our nominating and corporate governance committee oversees risk management activities relating to board composition. In addition, members of our senior management team attend our quarterly board meetings and are available to address any questions or concerns raised by the board on risk management and any other matters. Our board of directors believes that full and open communication between management and the board of directors is essential for effective risk management and oversight.

Communication with Our Directors

Any interested party with concerns about our company may report such concerns to the board of directors, or the chair of our board of directors, or otherwise the chair of the nominating and corporate governance committee, by submitting a written communication to the attention of such director at the following address:

Werewolf Therapeutics, Inc.

200 Talcott Ave, 2nd Floor, Watertown, Massachusetts 02472

Attention: Corporate Secretary

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

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

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

The audit committee oversees the procedures for the receipt, retention, and treatment of complaints received by us regarding accounting, internal accounting controls, or audit matters, and the confidential, anonymous submission by employees of concerns regarding questionable accounting, internal accounting controls or auditing matters. Concerns regarding questionable accounting or auditing matters or complaints regarding accounting, internal accounting controls or auditing matters may be submitted in writing to our senior legal officer, Chief Executive Officer or Chief Financial Officer at 200 Talcott Ave, 2nd Floor, Watertown, MA 02472 or via the toll-free telephone number 833-412-2334.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires our directors and executive officers, and persons who own more than ten percent of a registered class of our equity securities, to file with the SEC initial reports of ownership and reports of certain changes in ownership of common stock and other equity securities of our company. Such executive officers, directors and greater than ten percent stockholders are required by SEC regulation to furnish our company with copies of all Section 16(a) forms they file.

To our knowledge, based solely on our review of the reports provided to us and on representations received from our directors and executive officers, we believe that all of our directors, executive officers and persons who beneficially own more than 10 percent of our common stock complied with all Section 16(a) filing requirements applicable to them with respect to transactions during fiscal year 2022, with the following exceptions: a late Form 4 filing was made on behalf of each of Daniel Hicklin, Cynthia Seidel-Dugan, Reid Leonard, Ellen Lubman, Randi Isaacs, Tim Trost and Chulani Karunatilake, in each instance to report a single transaction which occurred on January 6, 2022.

(1)

Amounts shown for 2022 and 2021 represent the annual bonus earned by each of Drs. Hicklin, Isaacs and Seidel-Dugan based on our attainment of the corporate goals in the respective years as determined by the board of directors in its sole discretion, upon the recommendation of the compensation committee, or by the compensation committee in its sole discretion. Amounts shown for Dr. Isaacs in 2021 also include a $100,000 bonus earned by Dr. Isaacs in connection with our initial public offering that was completed in May 2021.

(2)

The amounts reported in the “Option Awards” column reflect the aggregate fair value of stock-based compensation awarded during the year computed in accordance with the provisions of the Financial Accounting Standard Board Accounting Standards Codification Topic 718, or ASC 718. See Note 10 to our consolidated financial statements appearing in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which was filed with the SEC on March 23, 2023, regarding assumptions underlying the valuation of equity awards. These amounts reflect the accounting cost for these stock options and do not reflect the actual economic value that may be realized by the named executive officer upon the vesting of the stock options, the exercise of the stock options, or the sale of the common stock underlying such stock options. On July 1, 2022, we granted stock option awards to each of the named executive officers, the vesting of which is subject to performance conditions. As of the grant date, the performance conditions were deemed not probable and, therefore, no value is included in the Option Awards or Total columns. Assuming the highest level of performance conditions will be achieved, the grant date fair values of these stock options are $922,891, $340,862 and $340,862 for Drs. Hicklin, Isaacs and Seidel-Dugan, respectively, calculated in accordance with ASC 718.

(3)

The amounts reported include life insurance premiums of $891 for each of Drs. Hicklin, Isaacs and Seidel-Dugan for 2022, and $612 for each of Drs. Hicklin, Isaacs and Seidel-Dugan for 2021. Further, the amounts reported include the payment of $1,589 for tax gross ups for long-term disability insurance for each of Drs. Hicklin, Isaacs and Seidel-Dugan for 2022, and $794 for tax gross ups for long-term disability insurance for each of Drs. Hicklin, Isaacs and Seidel-Dugan for 2021. Additionally, for 2022, the amounts reported include 401(k) contributions matched by the company for each of Drs. Hicklin, Isaacs and Seidel-Dugan in the amount of $9,150.

(4)	Dr. Hicklin is also a member of our board of directors but did not receive any additional compensation in his capacity as a director.

Narrative to Summary Compensation Table

Our executive compensation program is administered by the compensation committee of our board of directors, subject to the oversight and approval of our board of directors. Our compensation committee reviews our executive compensation practices on an annual basis and based on this review approves, or, as appropriate, makes recommendations to our board of directors for approval of, our executive compensation program. In designing our executive compensation program, our compensation committee considers compensation data for national and regional companies in the biotechnology/pharmaceutical industry provided by our independent compensation consultant to help guide its executive compensation decisions at the time of hiring and for subsequent adjustments in compensation. During the past fiscal year, the compensation committee retained Pearl Meyer & Partners, LLC, or Pearl Meyer, a compensation consulting firm, to advise the compensation committee on our compensation program for executive officers, which includes base salaries, annual performance-based cash incentives and equity incentive awards and Pearl Meyer made recommendations with respect to the amount and form of executive and director compensation. Although our compensation committee considers the advice and

TABLE OF CONTENTS

guidance of Pearl Meyer as to our executive compensation programs, our compensation committee ultimately makes its own decision about these matters. In the future, we expect that our compensation committee will continue to engage independent compensation consultants to provide additional guidance on our executive compensation programs and to conduct further competitive benchmarking against a peer group of publicly traded companies.

Base Salary

We use base salaries to recognize the experience, skills, knowledge and responsibilities required of all our employees, including our named executive officers. None of our named executive officers is currently party to an employment agreement or other agreement or arrangement that provides for automatic or scheduled increases in base salary.

In January 2022, we set the base salaries for 2022 for Drs. Hicklin, Isaacs and Seidel-Dugan of $530,400, $442,000 and $416,000, respectively.

Annual Bonus

The employment agreements for Drs. Hicklin, Isaacs and Seidel-Dugan provide that they will be eligible for annual bonuses up to a specified percentage of their salary, based upon the assessment of the board of directors (or a committee thereof), in its sole discretion, of the officer’s performance and our Company’s performance during the applicable fiscal year. These annual bonuses are calculated as a percentage of base salary and are designed to motivate our employees to achieve annual goals based on our strategic, financial and operating performance objectives. From time to time, our board of directors or our compensation committee may approve discretionary annual cash bonuses to our named executive officers.

The target annual bonus percentage for the 2022 bonuses was 50% for Dr. Hicklin, and 40% for each of Drs. Isaacs and Seidel-Dugan. With respect to 2022, we awarded bonuses of $275,278, $183,519 and $172,724 to Drs. Hicklin, Isaacs and Seidel-Dugan, respectively, based on our achievement of certain company goals and individual performance objectives as determined by the Compensation Committee, in the case of Drs. Hicklin, Isaacs and Seidel-Dugan.

Equity Incentives

Although we do not have a formal policy with respect to the grant of equity incentive awards to our executive officers, or any formal equity ownership guidelines applicable to them, we believe that equity grants provide our executive officers with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executive officers and our stockholders. In addition, we believe that equity grants with a time-based vesting feature promote executive retention because this feature incentivizes our executive officers to remain in our employment during the vesting period. Accordingly, our board of directors periodically reviews the equity incentive compensation of our executive officers, including our named executive officers, and from time to time may grant equity incentive awards to them in the form of stock options.

On January 6, 2022, we granted stock options to purchase 215,888 shares, 79,516 shares and 79,516 shares of our common stock to Drs. Hicklin, Isaacs and Seidel-Dugan, respectively. The options have a vesting commencement date of January 1, 2022 and vest over four years at a rate of 2.0833% of the shares vesting each month thereafter through January 1, 2026. On July 1, 2022, we granted performance-based stock options to purchase 274,670 shares, 101,447 shares and 101,447 shares of our common stock to Drs. Hicklin, Isaacs and Seidel-Dugan, respectively. These stock options vest only upon achievement of specified performance targets related to certain business objectives, with 60% of the shares vesting upon the achievement of one performance target and 40% of the shares vesting upon the achievement of a second performance target.

The vesting of the stock options granted to our named executive officers is subject to acceleration upon certain terminations of the officer’s employment with us, as described below under “-Employment Agreements with our Named Executive Officers.”

We use stock options to compensate our executive officers in the form of initial grants in connection with the commencement of employment and also at various times, often but not necessarily annually, if the board of directors or the compensation committee determines such awards are advisable. We have granted option awards to our executive officers with time-based vesting and performance-based vesting. The time-based vesting option

TABLE OF CONTENTS

awards that we have granted to our executive officers generally vest over four years following the vesting commencement date. Vesting rights cease upon termination of employment and exercise rights for stock options cease shortly after termination of employment. Prior to the exercise of a stock option, the holder has no rights as a stockholder with respect to the shares subject to such stock option, including no voting rights and no right to receive dividends or dividend equivalents. In addition, we may grant restricted stock units from time to time under the 2021 Stock Incentive Plan, or the 2021 Plan, but we have not done so to date.

The exercise price of all stock options granted since the closing of our initial public offering is equal to the fair market value of shares of our common stock on the date of grant, which we determine by reference to the closing market price of our common stock on the date of grant.

Employment Agreements with our Named Executive Officers

We entered into employment agreements with each of Drs. Hicklin, Isaacs and Seidel-Dugan that became effective on April 29, 2021. These employment agreements set forth the terms and conditions of each executive’s continued employment with us, including base salary, target annual bonus opportunity, standard employee benefit plan participation and certain benefits upon termination of the executive’s employment under specified conditions. The employment of all of our named executive officers is at will.

Under the employment agreements, Dr. Hicklin’s base salary was initially set at $510,000 and his annual target bonus amount was set at 50%, Dr. Isaacs’s base salary was initially set at $425,000 and her annual target bonus amount was set at 40%, and Dr. Seidel-Dugan’s base salary was set at $400,000 and her annual target bonus amount was set at 40%. The employment agreements provide that, in the event that the executive’s employment is terminated by us without “cause” or by the executive for “good reason,” then subject to the execution and effectiveness of a separation and release agreement, the executive will be entitled to receive (i) an amount equal to (x) 12 months of base salary in the case of Dr. Hicklin if such termination occurs more than three months prior to or more than 12 months following a “change in control,” and nine months of base salary in the case of Drs. Isaacs and Seidel-Dugan if such termination occurs prior to or more than 12 months following a change in control, in each case, payable on our regular payroll practices, or (y) 18 months of base salary in the case of Dr. Hicklin if such termination occurs within three months prior to or 12 months following a change in control, and 12 months base salary in the case of Drs.

In addition, the employment agreements provide that in the event of a termination of the executive’s employment by us without cause or by the executive for good reason then, subject to the timely execution of the separation and release agreement, the vesting of all unvested equity awards that vest solely on the passage of time held by the executive will be accelerated (i) as to six additional months of vesting if such termination occurs more than three months prior to or more than 12 months following a change in control in the case of Dr. Hicklin, or prior to or more than 12 months following a change in control in the case of Drs. Isaacs and Seidel-Dugan and (ii) in full if such termination occurs within three months prior to or 12 months following a change in control in the case of Dr. Hicklin, or within 12 months following a change in control in the case of Drs. Isaacs and Seidel-Dugan.

Pursuant to the terms of their employment agreements, each of our named executive officers has entered into standard form agreements with respect to non-competition, non-solicitation, confidential information and assignment of inventions.

401(k) Plan

We maintain a defined contribution employee retirement plan for our employees, including our named executive officers. The plan is intended to qualify as a tax-qualified 401(k) plan so that contributions to the 401(k) plan, and income earned on such contributions, are not taxable to participants until withdrawn or distributed from the 401(k) plan (except in the case of contributions under the 401(k) plan designated as Roth contributions). Under the 401(k) plan, each employee is fully vested in his or her deferred salary contributions and any qualified nonelective contributions made by us. Employee contributions are held and invested by the plan’s trustee as directed by participants. The 401(k) plan provides us with the discretion to match employee contributions. Beginning in 2022, the Company matches 50% of each participant’s contribution up to a maximum of 6% of the participant’s eligible compensation paid during the period.

Other Policies, Procedures, or Considerations

Anti-Hedging and Pledging Policy. Our insider trading policy expressly prohibits all of our employees, including our named executive officers, as well as our directors, family members and controlled entities from engaging in speculative transactions in our securities, including short sales, puts/calls, purchases of financial instruments that are designed to hedge or offset any decrease in the market value of our securities, and margin accounts or pledges.

TABLE OF CONTENTS

Rule 10b5-1 Sales Plans. Our directors and executive officers may adopt written plans, known as Rule 10b5-1 plans, in which they will contract with a broker to buy or sell shares of our common stock on a periodic basis. Under a Rule 10b5-1 plan, a broker executes trades pursuant to parameters established by the director or officer when entering into the plan, without further direction from the director or officer. It also is possible that the director or officer could amend the plan in certain circumstances when not in possession of material nonpublic information or terminate the plan. In addition, our directors and executive officers may buy or sell additional shares outside of a Rule 10b5-1 plan when they are not in possession of material nonpublic information.

The amounts reported in the “Option Awards” column reflect the aggregate grant-date fair value of stock-based compensation awarded during the year computed in accordance with the provisions of ASC 718. See Note 10 to our consolidated financial statements appearing in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which was filed on March 23, 2023 with the SEC, regarding assumptions underlying the valuation of equity awards. These amounts reflect the accounting cost for these stock options and do not reflect the actual economic value that may be realized by the directors upon the vesting of the stock options, the exercise of the stock options, or the sale of the common stock underlying such stock options.

As of December 31, 2022, the aggregate number of shares of our common stock subject to outstanding option awards for each non-employee director serving during 2022 was as follows: Dr. Evnin, 34,800 shares; Dr. Chatterjee, 30,933 shares; Dr. DiRocco, 34,800 shares; Dr. Lazarus, 34,800 shares; Dr. Morrison, 65,847 shares; and Mr. Sherman, 34,800 shares. Mr. Asanuma was not granted stock options.

(3)	Mr. Asanuma resigned from our board of directors effective April 15, 2022.

Dr. Hicklin, one of our directors who also serves as our president and chief executive officer, does not receive any additional compensation for his service as a director. Dr. Hicklin is one of our named executive officers and, accordingly, the compensation that we pay to Dr. Hicklin is discussed above under “Summary Compensation Table” and “Narrative to Summary Compensation Table.”

Our board of directors has approved a non-employee director compensation program that is designed to enable us to attract and retain, on a long-term basis, highly qualified non-employee directors. Under this director compensation program, we pay our non-employee directors a cash retainer for service on the board of directors and for service on each committee on which the director is a member. The chair of the board and of each committee receive higher retainers for such service. These fees are payable in arrears in four equal quarterly installments on the last day of each quarter, provided that the amount of such payment is prorated for any portion of such quarter that the director is not serving on our board of directors. The fees paid to non-employee directors for service on the board of directors and for service on each committee of the board of directors on which the director is a member are as follows:

	MEMBER ANNUAL FEE	CHAIR ADDITIONAL ANNUAL FEE
Board of Directors	$35,000	$30,000
Audit Committee	$7,500	$7,500
Compensation Committee	$5,000	$5,000
Nominating and Corporate Governance Committee	$4,000	$4,000

We also reimburse our non-employee directors for reasonable travel and other expenses incurred in connection with attending meetings of our board of directors and any committee of our board of directors on which they serve.

TABLE OF CONTENTS

In addition, under our director compensation program, each non-employee director, upon his or her election or appointment to our board of directors, receives an option to purchase 23,200 shares of our common stock under the 2021 Plan. In 2022, the number of shares subject to this new director grant was 23,200; in January 2023, our Compensation Committee amended the director compensation program to increase this number to 26,400. Each of these options vests with respect to one-third of such shares on the first anniversary of the grant date and thereafter in equal monthly installments until all shares are vested on the third anniversary of the grant date, subject to the non-employee director’s continued service as a director. Further, on the date of each annual meeting of stockholders, each non-employee director receives, under the 2021 Plan, an option to purchase 11,600 shares of our common stock under the 2021 Plan provided that if any director is initially elected to the board of directors in the twelve months preceding the annual meeting, the number of shares subject to the option will be pro-rated on a monthly basis for time in service (including partial months). In 2022, the number of shares subject to this annual grant was 11,600; in January 2023, our Compensation Committee amended the director compensation program to increase this number to 13,200. Each of these options vests in full on the earlier of the first anniversary of the grant date and the next annual meeting of stockholders following the grant date, subject to the non-employee director’s continued service as a director. All options issued to our non-employee directors under our director compensation program will be issued at exercise prices equal to the fair market value of our common stock on the date of grant and will have a term of ten years. Upon a change of control of our company any unvested options held by our non-employee directors will automatically vest.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

Since January 1, 2021, we have engaged in the following transactions in which the amounts involved exceeded $120,000 and any of our directors, executive officers or holders of more than 5% of our voting securities, or any member of the immediate family of, or person sharing the household with, the foregoing persons, had or will have a direct or indirect material interest. We believe that all of the transactions described below were made on terms no less favorable to us than could have been obtained from unrelated third parties.

Participation in Initial Public Offering

Amended and Restated Royalty Transfer Agreement

In December 2017, we entered into a royalty transfer agreement with MPM Oncology Impact Fund Charitable Foundation, Inc., or MPM Charitable Foundation, and UBS Optimus Foundation, or the Royalty Transfer Agreement. MPM Charitable Foundation is affiliated with MPM Capital, a holder of more than 5% of our capital stock. UBS Optimus Foundation is affiliated with UBS Oncology Impact Fund L.P., a holder of more than 5% of our capital stock. Under the Royalty Transfer Agreement, we are obligated to pay a royalty of 0.5% of net sales of our products to each of MPM Charitable Foundation and UBS Optimus Foundation. In August 2019, we amended the Royalty Transfer Agreement by entering into an amended and restated royalty transfer agreement, or the Amended Royalty Transfer Agreement, which provided that only products in our product pipeline at the time of our initial public offering or a change in control would be subject to the royalty on net sales. Under the Amended Royalty Transfer Agreement, our obligation to pay a royalty expires on a product-by-product and country-by-country basis upon the later of the 12th anniversary of the first commercial sale of such product in such country and expiration of the last valid claim in such country covering such product. The royalty rate is subject to a specified reduction for lack of any valid claim covering such product in a country. The obligation to pay royalties under the Amended Royalty Transfer Agreement shall not apply to any product that would only infringe our intellectual property rights that are discovered or developed after our initial public offering or to any product of an acquirer, assignee of the agreement or merger partner of ours so long as such product does not incorporate any of our pre-acquisition intellectual property.

Additionally, in December 2017, we entered into a royalty direction letter, which was amended and restated in August 2019, with MPM Charitable Foundation, UBS Optimus Foundation and UBS Oncology Impact Fund L.P., pursuant to which we agreed that a portion of the consideration received from UBS Oncology Impact Fund L.P. for the purchase of shares of Series A preferred stock in connection with our Series A preferred stock financing was to be treated as consideration for the royalty on net sales under the Amended Royalty Transfer Agreement. Affiliates of MPM Capital and UBS Oncology Impact Fund L.P. that own shares of our common stock hold interests in MPM Charitable Foundation and UBS Optimus Foundation.

Registration Rights

We are a party to an amended and restated investor rights agreement with certain holders of our common stock, including some of our 5% stockholders and their affiliates. This investor rights agreement provides these stockholders the right, subject to certain conditions, to demand that we file a registration statement or to request that their shares be covered by a registration statement that we are otherwise filing.

Indemnification Agreements

Our restated certificate of incorporation provides that we will indemnify our directors and officers to the fullest extent permitted by Delaware law. In addition, we have entered into indemnification agreements with all of our directors and executive officers. These indemnification agreements may require us, among other things, to indemnify each such director or executive officer for some expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by him or her in any action or proceeding arising out of his or her service as one of our directors or executive officers.

Sublease Agreement

In May 2022, we entered into a sublease agreement with Crossbow, to sublease to Crossbow the entirety of our office and laboratory space in Cambridge, Massachusetts. The term of the sublease agreement commenced in June 2022 and ends in March 2024, with no option to extend. We received cash payments under this sublease of approximately $0.8 million during the year ended December 31, 2022. In addition, we received $0.2 million from Crossbow in June 2022 as a security deposit.

Dr. Morrison serves as the Chief Executive Officer of Crossbow and holds 5% of Crossbow’s outstanding common stock. Additionally, certain entities affiliated with MPM Capital are beneficial owners of Crossbow. Dr. Evnin co-founded MPM Capital and currently serves as Managing Director, and Dr. Morrison currently serves as Executive Partner.

Policies and Procedures for Related Person Transactions

Our board of directors has adopted written policies and procedures for the review of any transaction, arrangement or relationship in which our company is a participant, the amount involved exceeds $120,000, and one of our executive officers, directors, director nominees or holders of more than 5% of our capital stock (or their immediate family members), each of whom we refer to as a “related person,” has a direct or indirect material interest.

A related person transaction reviewed under the policy will be considered approved or ratified if it is authorized by the audit committee after full disclosure of the related person’s interest in the transaction. As appropriate for the circumstances, the audit committee will review and consider:

•	the related person’s interest in the related person transaction;

•	the approximate dollar value of the amount involved in the related person transaction;

•	the approximate dollar value of the amount of the related person’s interest in the transaction without regard to the amount of any profit or loss;

•	whether the transaction was undertaken in the ordinary course of our business;

•	whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unrelated third party;

•	the purpose of, and the potential benefits to us of, the transaction; and

•	any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.

Our audit committee may approve or ratify the transaction only if it determines that, under all of the circumstances, the transaction is in, or is not inconsistent with, our best interests. Our audit committee may impose any conditions on the related person transaction that it deems appropriate.

TABLE OF CONTENTS

In addition to the transactions that are excluded by the instructions to the SEC’s related person transaction disclosure rule, our board of directors has determined that the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not related person transactions for purposes of this policy:

•

interests arising solely from the related person’s position as an executive officer of another entity, whether or not the person is also a director of the entity, that is a participant in the transaction where the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity, the related person, and his or her immediate family members are not involved in the negotiation of the terms of the transaction and do not receive any special benefits as a result of the transaction and the amount involved in the transaction is less than the greater of $200,000 or 5% of the annual gross revenues of the company receiving payment under the transaction; and

•	a transaction that is specifically contemplated by provisions of our certificate of incorporation or bylaws.

The policy provides that transactions involving compensation of executive officers shall be reviewed and approved by our compensation committee in the manner specified in the compensation committee’s charter.

TABLE OF CONTENTS

HOUSEHOLDING

Some banks, brokers, and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of our documents, including the Notice of Internet Availability of Proxy Materials or, if requested, the 2022 Annual Report and proxy statement, may have been sent to multiple stockholders in your household unless you have requested otherwise. We will promptly deliver a separate copy of any of the above documents to you if you write or call us at Werewolf Therapeutics, Inc., 200 Talcott Ave, 2nd Floor, Watertown, Massachusetts 02472, Attention: Corporate Secretary, telephone: 617-952-0555. If you want to receive separate copies of the Notice of Internet Availability of Proxy Materials, proxy statement or annual report to stockholders in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker or other nominee record holder, or you may contact us at the above address and phone number.

STOCKHOLDER PROPOSALS FOR OUR 2024 ANNUAL MEETING

A stockholder who would like to have a proposal considered for inclusion in our 2024 proxy statement must submit the proposal in accordance with the procedures outlined in Rule 14a-8 of the Exchange Act so that it is received by us no later than December 29, 2023. However, if the date of the 2023 annual meeting of stockholders is changed by more than 30 days from the date of the previous year’s meeting, then the deadline is a reasonable time before we begin to print and send our proxy statement for the 2023 annual meeting of stockholders. SEC rules set standards for eligibility and specify the types of stockholder proposals that may be excluded from a proxy statement. Stockholder proposals should be addressed to Werewolf Therapeutics, Inc., 200 Talcott Ave, 2nd Floor, Watertown, Massachusetts 02472, Attention: Corporate Secretary.

If a stockholder wishes to propose a nomination of persons for election to our board of directors or present a proposal at an annual meeting but does not wish to have the proposal considered for inclusion in our proxy statement and proxy card, our amended and restated bylaws establish an advance notice procedure for such nominations and proposals. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the board of directors 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 notice in proper form to our Corporate Secretary of the stockholder’s intention to bring such business before the meeting.

The required notice must be in writing and received by our Corporate Secretary at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary of the preceding year’s annual meeting. However, in the event that the date of the annual meeting is advanced by more than 30 days, or delayed by more than 60 days, from the first anniversary of the preceding year’s annual meeting, a stockholder’s notice must be so received no earlier than the 120th day prior to such annual meeting and not later than the close of business on the later of (A) the 90th day prior to such annual meeting and (B) the tenth day following the day on which notice of the date of such annual meeting was mailed or public disclosure of the date of such annual meeting was made, whichever first occurs. For stockholder proposals to be brought before the 2024 annual meeting of stockholders, the required notice must be received by our Corporate Secretary at our principal executive offices no earlier than February 22, 2024 and no later than March 23, 2024.

In addition to satisfying the provisions in our bylaws relating to nominations of director candidates, including the deadline for written notices, to comply with the SEC’s universal proxy rule, shareholders who intend to solicit proxies in support of director nominees other than the Company’s nominees in compliance with Rule 14a-19 under the Exchange Act must provide notice that sets forth the information required by Rule 14a-19 no later than April 21, 2024. If the date of the 2024 annual meeting changes by more than 30 calendar days from the first anniversary of the Annual Meeting, such notice must instead be provided by the later of 60 calendar days prior to the date of the 2024 Annual Meeting or the 10th calendar day following public announcement by us of the date of the 2024 Annual Meeting.
