On September 24, 2026, upon the recommendation of the Nominating and Corporate Governance Committee of the Board of Directors (the “Board”) of Hemab Therapeutics Holdings, Inc.

There are no arrangements or understandings between Ms. Walbert and any other persons pursuant to which she was elected as a director. Ms. Walbert has no family relationships with any of the Company’s directors or executive officers.
