Appointment of Director

On July 18, 2025, the Board of Directors (the “Board”) of Senti Biosciences, Inc. (the “Company”) approved the appointment of Bryan Baum to the Board. Mr. Baum’s appointment was made pursuant to the terms of a letter agreement dated as of December 2, 2024, by and between the Company and Celadon Partners SPV 24. In connection with Mr. Baum’s appointment, the Board approved an increase in the authorized number of members of the Board from seven to eight members. Mr. Baum was appointed to fill the vacancy created by the foregoing increase in the size of the Board, as a Class II director of the Company, to serve in such capacity until the annual meeting of the Company’s stockholders in 2027 or until his earlier resignation, death or removal. Mr. Baum is not currently expected to serve on any of the standing committees of the Board.

Mr. Baum, age 36, is a serial entrepreneur who has founded and sold multiple companies including Blue Vision Labs, a localization and mapping software company for self-driving cars (sold to Lyft in 2018); Operam, a data analytics and marketing insights company; and Represent.com, an e-commerce platform (sold to CustomInk in 2016). Mr. Baum has been an angel investor for over a decade and has personally made over 200 investments in companies such as Uber, Airbnb, Slack, Flexport, Carta, PillPack, and Sweetgreen. He is currently a Managing Partner of K5 Global, a venture capital firm he co-founded in January 2020. Mr. Baum studied Game Theory at Swarthmore College and Oxford University. The Company believes Mr. Baum is qualified to serve on the Board because of his financial and investment management expertise.

Mr. Baum will be compensated for his service as a non-employee director in accordance with the Company’s Amended and Restated Non-Employee Director Compensation Policy, as more fully described in the Company’s Proxy Statement on Schedule 14A filed with the Securities and Exchange Commission on April 30, 2025. In accordance with those arrangements, Mr. Baum was granted an initial option award to purchase 43,900 shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), pursuant to the Company’s Amended and Restated 2022 Equity Incentive Plan (the “A&R Plan”), which will vest in equal monthly installments over three years from its grant date, subject to Mr. Baum’s continued service on the Board; provided, that upon a Change of Control (as defined in the A&R Plan), all shares of Common Stock subject to the option shall become fully vested and exercisable, provided, further, however, that all vesting shall cease if Mr. Baum resigns from the Board or otherwise ceases to serve as a director of the Company, unless the Company and Mr. Baum have entered into a written agreement for Mr. Baum to provide uninterrupted services to the Company in a capacity other than as a director at such time or prior to such time Mr. Baum resigns from or ceases to serve as a director, and such written agreement expressly states that such services constitute Continuous Service (as defined in the A&R Plan), in which case, all vesting shall cease upon termination of the Continuous Service. As a non-employee director, Mr. Baum will also be eligible to receive an annual stock option grant to purchase 21,950 shares of Common Stock, as well as annual cash retainers of $35,000 for serving as a member of the Board.

Mr. Baum has no family relationship with any of the executive officers or directors of the Company. Mr. Baum is not a party to any transaction with the Company that would require disclosure under Item 404(a) of Regulation S-K, and, except as described above, there are no arrangements or understandings between Mr. Baum and any other persons pursuant to which he was selected as director.

In connection with Mr. Baum’s election to the Board, Mr. Baum will enter into the Company’s standard form of indemnification agreement, a copy of which was filed as Exhibit 10.5 to the Company’s Registration Statement on Form S-4, as amended (File No. 333- 262707) filed with the Securities and Exchange Commission on May 10, 2022. Pursuant to the terms of the indemnification agreement, the Company may be required, among other things, to indemnify Mr. Baum for certain expenses, including attorneys’ fees, judgments, fines, penalties, excise taxes and settlement amounts actually and reasonably incurred by him in any action or proceeding arising out of his service as one of the Company’s directors.

Item 7.01 Regulation FD Disclosure.

On July 18, 2025, the Company issued a press release announcing the appointment of Mr. Baum to the Board. A copy of the press release is being furnished as Exhibit 99.1 to this Current Report on Form 8-K.
