Item 5.02

Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On April 13, 2023, upon the recommendation of the Nominating and Corporate Governance Committee of the Board of Directors (the “Board”) of Poseida Therapeutics, Inc. (the “Company”), the Board appointed Rafael Amado, M.D., as a director of the Company. Dr. Amado will serve as a Class III director with an initial term expiring at the Company’s 2023 annual meeting of stockholders (the “2023 Annual Meeting”), or until his earlier death, resignation, or removal.

There are no arrangements or understandings between Dr. Amado and any other persons pursuant to which he was selected as a director of the Company. There is no transaction involving Dr. Amado that requires disclosure under Item 404(a) of Regulation S-K.

Dr. Amado will be entitled to receive cash and equity compensation for his service as a director of the Company pursuant to the Company’s amended and restated non-employee director compensation policy, a copy of which is filed as Exhibit 10.1 to the Company’s Quarterly Report on Form 10-Q (File No. 333-239321), filed with the Securities and Exchange Commission on August 11, 2022. Pursuant to the director compensation policy, Dr. Amado will receive (i) an initial option grant to purchase 55,200 shares of the Company’s common stock, and (ii) an initial restricted stock unit award covering 39,300 shares of the Company’s common stock, in each case vesting monthly or annually, respectively, over a three-year period. In addition, Dr. Amado will be paid a $40,000 annual cash retainer for his service on the Board, payable in arrears on a quarterly basis and pro-rated for any partial months of service. The Board has determined that Dr. Amado will not receive an “Annual Grant” as defined in the director compensation policy at the Company’s 2023 Annual Meeting given the proximity of Dr. Amado’s appointment and the anticipated date of the 2023 Annual Meeting.

The Company also entered into its standard form of indemnity agreement with Dr. Amado, a copy of which is filed as Exhibit 10.1 to the Company’s Registration Statement on Form S-1 (File No. 333-239321), filed with the Securities and Exchange Commission on June 19, 2020.
