Item 3.03.

Material Modification to Rights of Security Holders.

On March 5, 2024, Sensei Biotherapeutics, Inc. (the “Company”) and Equiniti Trust Company, LLC (formerly known as American Stock Transfer & Trust Company, LLC) (the “Rights Agent”) entered into the Second Amendment to Stockholder Rights Agreement (the “Second Amendment”), amending the Stockholder Rights Agreement, dated as of March 7, 2023, as previously amended by the Amendment to Stockholder Rights Agreement, dated as of June 23, 2023, between the Company and the Rights Agent (the “Rights Agreement”).

The Second Amendment changes the final expiration date of the Rights (as defined in the Rights Agreement) from 5:00 p.m., New York City time on March 7, 2024 to 5:00 p.m., New York City time on March 7, 2025. The Rights may still be earlier redeemed, exchanged or terminated in accordance with the terms of the Rights Agreement. The Second Amendment also eliminates terms providing that, for purposes of the Rights Agreement, a person is deemed to beneficially own shares of the Company held by any other person with which such person is “acting in concert” (as previously defined in the Rights Agreement).

This description of the Second Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Second Amendment, which is filed as Exhibit 4.3 hereto and is incorporated herein by reference.
