On April 24, 2026, Senti Biosciences, Inc. ("Senti") implemented a holding company reorganization in accordance with Section 251(g) of the General Corporation Law of the State of Delaware (the "Holding Company Reorganization") pursuant to the Agreement and Plan of Merger, dated as of April 24, 2026 (the "Merger Agreement"), by and among Senti, Senti Biosciences Holdings, Inc., a newly formed Delaware corporation ("Senti Biosciences Holdings"), and Senti Biosciences Merger Sub, Inc., a newly-formed Delaware corporation ("Merger Sub"). Pursuant to the Holding Company Reorganization, Senti merged with and into Merger Sub, a direct wholly owned subsidiary of Senti Holdings, Inc. ("Senti Holdings") and an indirect wholly owned subsidiary of Senti Biosciences Holdings and Senti, with Senti surviving as a direct wholly owned subsidiary of Senti Holdings, which is a direct wholly owned subsidiary of Senti Biosciences Holdings. At the Effective Time (as defined in the Merger Agreement), (i) the separate existence of Merger Sub ceased and (ii) each share of Senti common stock, par value $0.0001 per share ("Senti Common Stock"), issued and outstanding immediately prior to the Effective Time, was automatically converted into one share of Senti Biosciences Holdings common stock, par value $0.0001 per share, having the same designation, rights, powers, and preferences, and qualifications, limitations, and restrictions as a share of Senti Common Stock immediately prior to consummation of the Holding Company Reorganization. The Holding Company Reorganization constitutes a succession for purposes of Rule 12g-3(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). This Form 15 relates solely to the reporting obligations of Senti under the Exchange Act and does not affect the reporting obligations of Senti Biosciences Holdings, which is the successor to Senti under the Exchange Act.

Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has caused this certification/notice to be signed on its behalf by the undersigned duly authorized person.
