⁽¹⁾Redmile Group, LLC’s (“Redmile”) beneficial ownership of the Issuer’s common stock (“Common Stock”) is comprised of 4,892,902 shares of Common Stock owned by certain private investment vehicles and/or sub-advised accounts managed by Redmile, including Redmile Biopharma Investments III, L.P. (“RBI III”). Subject to the Beneficial Ownership Blocker (as defined below), Redmile may also be deemed to beneficially own 1,324,740 shares of Common Stock issuable upon exercise of certain pre-funded warrants to purchase Common Stock (the “Warrants”). Pursuant to the terms of the Warrants, the Issuer may not effect any exercise of the Warrant, and a holder of a Warrant does not have the right to exercise the Warrant held by such holder, to the extent that after giving effect to such issuance after exercise, the holder (together with the holder’s affiliates, and any other persons acting as a group together with the holder or any of the holder’s affiliates), would beneficially own in excess of 9.99% (the “Beneficial Ownership Limitation”) of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issued upon exercise of the Warrant (the “Beneficial Ownership Blocker”). The Beneficial Ownership Limitation may be changed at a holder’s election upon 61 days’ notice to the Issuer. The 4,942,312 shares of Common Stock reported as beneficially owned by Redmile in this Schedule 13G represent 9.99% of the outstanding shares of Common Stock (calculated in accordance with footnote (2) below). The reported securities may be deemed beneficially owned by Redmile as investment manager of such private investment vehicles and/or sub-advised accounts. The reported securities may also be deemed beneficially owned by Jeremy C. Green as the principal of Redmile. Redmile and Mr. Green each disclaim beneficial ownership of these shares, except to the extent of its or his pecuniary interest in such shares, if any.

⁽²⁾Percentage based on the sum of (a) 49,423,188 shares of Common Stock outstanding as of July 25, 2024, as reported by the Issuer in its Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2024 filed with the Securities and Exchange Commission on August 1, 2024 (the “Form 10-Q”), plus (b) 49,410 shares of Common Stock issuable upon exercise of the Warrants, which due to the Beneficial Ownership Limitation is the maximum number of shares that could be issued upon exercise of the Warrants.
