Under the terms of the Agreement and Plan of Merger, dated as of December 23, 2024, by and among, the Issuer, Merger Sub I, a wholly-owned subsidiary of the Issuer ("Merger Sub I"), Merger Sub II, a wholly-owned subsidiary of the Issuer ("Merger Sub II") and Inmagene Biopharmaceuticals ("Legacy Inmagene") (the "Merger Agreement"), on July 25, 2025, Merger Sub I merged with and into Legacy Inmagene (the "First Merger"), with Legacy Inmagene surviving the First Merger as a wholly-owned subsidiary of the Issuer, and immediately after the First Merger, Legacy Inmagene merged with and into Merger Sub II, with Merger Sub II surviving the Merger as a wholly-owned subsidiary of the Issuer (the "Second Merger" and together with the First Merger, the "Merger"). (continued in the next footnote).
Upon the closing of the First Merger, each Legacy Inmagene ordinary and preferred share was converted into the right to receive 0.003051 of shares of the Issuer common stock.
