 Foundation, the California Life Sciences Association and the Salk Institute. Dr. Rosen previously served on the board of directors of PACT Pharma, Inc. from December 2016 until October 2022. Dr. Rosen holds a B.S. in Chemistry from the University of Michigan and a Ph.D. in Chemistry from the University of California, Berkeley. We believe that Dr. Rosen should serve as a director based on his position as one of our founders and as our Chief Executive Officer, his extensive experience in general management and business development and his experience in the field of biosciences.

### CORPORATE GOVERNANCE

#### Independence of The Board of Directors
As required under the NYSE listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors. The Board consults with counsel to ensure that the Board’s determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of the NYSE, as in effect from time to time.

Consistent with these considerations, after a review of all relevant identified transactions or relationships between each director, or any of his or her family members, and us, including our senior management and independent auditors, the Board has affirmatively determined that the following seven directors are independent directors within the meaning of the applicable NYSE listing standards: Ms. Falberg, Dr. Kaneko, Dr. Lacey, Ms. Lambert, Mr. Machado, Dr. Perlman and Dr. Ribas. In making this determination, the Board found that none of these directors had a material or other disqualifying relationship with us. Dr. Rosen is not independent by virtue of being one of our executive officers, and Dr. Berger, Dr. Higgins and Ms. Mercier are not independent by virtue of their relationship with Gilead.

#### Board Leadership Structure
Our Bylaws and Corporate Governance Guidelines provide the Board with the flexibility to combine or separate the positions of Chairman of the Board and Chief Executive Officer. Dr. Rosen, our Chief Executive Officer, currently serves as our Chairman of the Board and Dr. Kaneko serves as our lead independent director. As lead independent director, Dr. Kaneko presides over periodic meetings of our independent directors, serves as a liaison between our Chief Executive Officer and the independent directors and performs such additional duties as the Board may otherwise determine and delegate.
