NOTICE OF 2024 ANNUAL MEETING OF STOCKHOLDERS

To Be Held on Wednesday, May 22, 2024

Dear Stockholder:

You are cordially invited to the 2024 Annual Meeting of Stockholders (the “2024 Annual Meeting”) of Dyne Therapeutics, Inc. The 2024 Annual Meeting will be held exclusively via the Internet in a virtual meeting format at www.proxydocs.com/DYN on Wednesday, May 22, 2024 at 8:00 a.m. Eastern Time. At the meeting, the stockholders will consider and vote on the following matters:

  1. The election of three Class I directors, Carlo Incerti, M.D., Catherine Stehman-Breen, M.D. and John G. Cox, each to serve for a three-year term expiring at the 2027 annual meeting of stockholders and until his or her respective successor has been duly elected and qualified;

  2. The ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024; and

  3. The transaction of any other business that may properly come before the 2024 Annual Meeting or any adjournment or postponement thereof.

You may attend the 2024 Annual Meeting online atwww.proxydocs.com/DYN, where you will be able to vote your shares electronically during the meeting and submit questions during the meeting. Stockholders will not be able to attend the annual meeting in person. In order to attend the 2024 Annual Meeting online, you must register in advance at www.proxydocs.com/DYNprior to the commencement of the Annual Meeting. Upon completing your registration, you will receive further instructions via email, including a unique link that will allow you access to the 2024 Annual Meeting and to vote and submit questions during the 2024 Annual Meeting. Please follow the instructions found on your Notice Regarding the Availability of Proxy Materials, Proxy Card and/or Voting Instruction Card and subsequent instructions that will be delivered to you via email.

Stockholders of record at the close of business on March 28, 2024 will be entitled to notice of and to vote electronically during the 2024 Annual Meeting or any adjournment or postponement thereof. A list of registered stockholders as of the close of business on the record date will be available for examination by any stockholder for any purpose germane to the 2024 Annual Meeting during normal business hours at our principal executive offices at 1560 Trapelo Road, Waltham, Massachusetts 02451 during the 10-day period ending on the day before the 2024 Annual Meeting. We have elected to provide access to our proxy materials over the Internet under the Securities and Exchange Commission’s “notice and access” rules. We believe that providing our proxy materials over the Internet expedites stockholders’ receipt of proxy materials, lowers costs and reduces the environmental impact of our annual meeting.

We encourage all stockholders to attend the 2024 Annual Meeting online. However, whether or not you plan to attend the 2024 Annual Meeting, we encourage you to read the proxy statement and submit your proxy or voting instructions as soon as possible.
