This Amendment No. 1 (the “Amendment”) amends the Registration Statement on Form 8-A originally filed by Tempest Therapeutics. Inc. (the “Company”) with the Securities and Exchange Commission (the “SEC”) on October 11, 2023. The Amendment is being filed to amend the description of preferred stock purchase rights (the “Rights”) of the Company. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Rights Agreement (as defined below).

Item 1. Description of Securities to be Registered.

On October 9, 2024, the Company entered into Amendment No. 1 (the “Amendment”) to the Rights Agreement, dated as of October 10, 2023, by and between the Company and Computershare Trust Company, N.A., as rights agent (as amended, the “Rights Agreement”). Capitalized terms used but not otherwise defined in this Item 1 shall have the meanings ascribed to such terms in the Rights Agreement.

The Amendment extends the Final Expiration Date of the Rights Agreement until immediately following the Company’s 2025 Annual Meeting of Stockholders or, if Tempest’s stockholders approve the Rights Plan at or prior to such meeting, to October 10, 2026, unless the Rights are earlier redeemed or exchanged by the Company. The Company does not have any obligation under the Rights Agreement to seek stockholder approval for the Rights Agreement. The Rights Agreement otherwise remains unmodified and in full force and effect in accordance with its terms.

The foregoing description does not purport to be complete and is qualified in its entirety by reference to the complete text of the Rights Agreement, a copy of which is filed as Exhibit 4.1 to the Current Report on Form 8-K filed by the Company with the SEC on October 11, 2023, and the Amendment, a copy of which is filed as Exhibit 4.2 to the Current Report on Form 8-K filed by the Company with the SEC on the date hereof, each of which is incorporated by reference into this Item 1.
