F1 Reflects a 1:12 reverse stock split effective on July 25, 2025 prior to the First Effective Time (as defined below) (the "Reverse Stock Split").
F2 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).
F3 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. Subsequent to the Merger, the name of the Issuer was changed from Ikena Oncology, Inc. ("Ikena") to ImageneBio, Inc. (continued in the next footnote).
F4 Immediately prior to the effective time of the First Merger (the "First Effective Time"), each unexpired, unexercised and unvested option to purchase Ikena common stock (each, an "Ikena option") granted under the Ikena 2021 Stock Option and Incentive Plan (each, a "2021 Ikena option") was accelerated in full and, effective as of the First Effective Time, each unexpired, unexercised and fully vested 2021 Ikena option was automatically cancelled and extinguished and, in exchange, each former holder of any such 2021 Ikena option received a number of shares of Ikena common stock equal to (A) the product of (x) the aggregate number of shares of Ikena common stock subject to or underlying such Ikena option multiplied by (y) (i) $2.3647 minus (ii) the exercise or strike price of the Ikena option, divided by (B) $2.3647 (such transaction, the "2021 Ikena option acceleration").
