⁽¹⁾ The beneficial ownership of RedCo II Master Fund, L.P. (“RedCo II”) is comprised solely of 8,197,331 shares of Common Stock issuable upon exercise of certain Pre-Funded Warrants to Purchase Common Stock (the “Warrants” and the shares issuable thereunder, the “Warrant Shares”) under the Beneficial Ownership Blocker (as defined below). The reported securities may be deemed beneficially owned by Redmile Group, LLC as investment manager of RedCo II, and also may be deemed beneficially owned by Jeremy C. Green as the principal of Redmile Group, LLC. Redmile Group, LLC 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. Pursuant to the terms of the Warrants, a holder of a Warrant does not have the right to exercise any portion of the Warrant held by such holder, and any such exercise shall be void ab initio, to the extent (but only 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 Warrant Shares 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 8,197,331 Warrant Shares reported as beneficially owned by RedCo II in this Schedule 13G represent the maximum amount of Common Stock issuable to RedCo II under the Beneficial Ownership Blocker (calculated in accordance with footnote (2) below).

 

⁽²⁾ Percentage based on 131,306,404 shares of Common Stock deemed outstanding, based on the outstanding shares of Common Stock reported by the Issuer in its quarterly report on Form 10-Q for the quarterly period ended June 30, 2024 filed with the SEC on August 13, 2024 (the “Form 10-Q”), the Warrant Shares issued upon exercise of certain Warrants since the filing of the Form 10-Q, and the reported Warrant Shares, which, due to the Beneficial Ownership Limitation, is the maximum number of shares that could be issued to RedCo II upon exercise of the Warrants.
