On November 1, 2023, Aaron Royston, M.D. resigned from the Board of Directors (the “Board”) of RayzeBio, Inc. (the “Company”). Dr. Royston’s decision to resign from the Board was voluntary and not as a result of any disagreement with the Company concerning any matter relating to its operations, policies or practices.

On November 1, 2023, upon the recommendation of the Nominating and Corporate Governance Committee of the Board, the Board appointed Tim Van Hauwermeiren, M.Sc. EMBA to fill the vacancy created by Dr. Royston’s resignation. Mr. Van Hauwermeiren will serve as a Class I director, with an initial term expiring at the Company’s 2024 annual meeting of stockholders.
Mr. Van Hauwermeiren is the co-founder and has served as Chief Executive Officer of argenx SE, a biopharmaceutical company, since 2008, and has served as a member of the Board of Directors of argenx SE since 2017. Mr. Van Hauwermeiren also serves on the board of iTeos Therapeutics, a public clinical-stage biopharmaceutical company. Mr. Van Hauwermeiren holds a B.Sc. and M.Sc. in bioengineering from Ghent University (Belgium) and an Executive MBA from The Vlerick School of Management.
Pursuant to the Company’s non-employee director compensation policy, Mr. Van Hauwermeiren was granted on the date of his appointment an option to purchase 48,628 shares of the Company’s common stock, which vest in substantially equal monthly installments over the three years following his appointment to the Board, subject to Mr. Van Hauwermeiren’s Continuous Service (as defined in the Company’s 2023 Equity Incentive Plan (the “Plan”)) through each such vesting date, and will vest in full upon a Change in Control (as defined in the Plan), subject to Mr. Van Hauwermeiren’s Continuous Service through such date. Mr. Van Hauwermeiren will receive cash compensation for his service on the Board in accordance with the Company’s non-employee director compensation policy, as such policy may be amended from time to time.

There is no arrangement or understanding between Mr. Van Hauwermeiren and any other person pursuant to which Mr. Van Hauwermeiren was appointed as a director, and there is no family relationship between Mr. Van Hauwermeiren and any of the Company’s other directors or executive officers. Mr. Van Hauwermeiren is not a party to any transaction that would require disclosure under Item 404(a) of Regulation S-K promulgated under the Securities Act of 1933, as amended.
