    Item 4.Ownership
    (a)Amount beneficially owned:

     

    As of the close of business on September 30, 2024, the Reporting Persons and a certain Partners managed account (the “Partners Managed Account”) held Pre-Funded Warrants (the “Pre-Funded Warrants”) exercisable for an aggregate of 12,060,526 Shares. The Pre-Funded Warrants are exercisable at any time at an exercise price of $0.0001 per Share and do not expire. A holder of Pre-Funded Warrants will not have the right to exercise any portion of its Pre-Funded Warrants which, upon giving effect to such exercise, would cause the aggregate number of Shares beneficially owned by the holder (together with its affiliates and other attribution parties (as defined in the Pre-Funded Warrant)) to exceed 4.99% of the Shares outstanding immediately after such exercise (the “Pre-Funded Warrants Blocker”). The 4.99% ownership limitation applicable to the Pre-Funded Warrants held by the Reporting Persons and the Partners Managed Account was increased to 9.99% in accordance with the terms of the Pre-Funded Warrants Blocker. Accordingly, as of the close of business on September 30, 2024, based on the 9.99% ownership limitation, the Pre-Funded Warrants Blocker limits the exercise of the Pre-Funded Warrants held by the Reporting Persons and the Partners Managed Account to 2,083,529 out of the 12,060,526 Shares underlying the Pre-Funded Warrants held by them.

     

    As of the close of business on September 30, 2024, (i) BVF beneficially owned 3,681,509 Shares, including 2,083,529 Shares underlying certain Pre-Funded Warrants held by it and excluding 4,289,365 Shares underlying certain Pre-Funded Warrants held by it, (ii) BVF2 beneficially owned 1,210,605 Shares, excluding 4,983,846 Shares underlying the Pre-Funded Warrants held by it, and (iii) Trading Fund OS beneficially owned 140,576 Shares, excluding 503,238 Shares underlying the Pre-Funded Warrants held by it.

     

    BVF GP, as the general partner of BVF, may be deemed to beneficially own the 3,681,509 Shares beneficially owned by BVF.

    Mr. Lampert, as a director and officer of BVF Inc., may be deemed to beneficially own the 5,073,003 Shares beneficially owned by BVF Inc.

BVF GP disclaims beneficial ownership of the Shares beneficially owned by BVF. BVF2 GP disclaims beneficial ownership of the Shares beneficially owned by BVF2. Partners OS disclaims beneficial ownership of the Shares beneficially owned by Trading Fund OS. BVF GPH disclaims beneficial ownership of the Shares beneficially owned by BVF and BVF2.
