NOTICE OF 2025 ANNUAL MEETING OF STOCKHOLDERS

To Be Held on June 12, 2025

Dear Stockholders:

You are cordially invited to virtually attend the 2025 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/HOWL2025 on Thursday, June 12, 2025, at 9:00 a.m., Eastern time.

Only stockholders who owned shares of our common stock at the close of business on April 14, 2025, 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 I directors nominated by our board of directors, each to serve for a three-year term expiring at the 2028 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, 2025; 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 I 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, 2024, or the 2024 Annual Report. We will mail the Notice of Availability on or about April 28, 2025, 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 2024 Annual Report, and a form of proxy card.

Stockholders of record at the close of business on April 14, 2025, 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 stockholders of record during the Annual Meeting for examination at www.virtualshareholdermeeting.com/HOWL2025. Further information about how to attend the Annual Meeting online, vote your shares and submit questions during the meeting is included in the accompanying proxy statement.

Whether or not you plan to attend the Annual Meeting online, we urge you to take the time to vote your shares.

By Order of the Board of Directors,

Daniel J. Hicklin, President and Chief Executive Officer

Watertown, MA
