Comment for Type of Reporting Person: This total excludes 2,900,662 shares of Common Stock issuable upon the conversion of shares of Series C non-voting convertible preferred stock (the Series C Preferred Stock), which are not convertible within 60 days of this Statement because the Series C Preferred Stock may not be converted into Common Stock to the extent that doing so would result in the holder of the Series C Preferred Stock beneficially owning more than 4.99 percent of the shares of Common Stock then outstanding immediately after giving effect to such conversion (the Beneficial Ownership Limitation). These securities are held of record by TCG Crossover II (as defined in Item 2(a) below). TCG Crossover GP II (as defined in Item 2(a) below) is the general partner of TCG Crossover II and may be deemed to have voting, investment, and dispositive power with respect to these securities. Chen Yu is the sole managing member of TCG Crossover GP II and may be deemed to share voting, investment and dispositive power with respect to these securities.
Based on 38,242,757 outstanding as of May 5, 2026, following the underwritten offering that closed on May 5, 2026 (the Offering), as reported by the Issuer (as defined in Item 1(a) below) in its final prospectus filed with the United States Securities and Exchange Commission (the Commission) on May 7, 2026 (the Prospectus), assuming that the underwriters do not exercise their option to purchase an additional 3,169,500 shares (the Option).
