        <footnote id="F2">The reported securities may also be deemed to be beneficially owned by R01 Fund LP (&quot;R01 LP&quot;), R01 Capital LLC (&quot;R01 Capital&quot;) and R01 Capital Manager LLC (&quot;R01 Capital Manager&quot; and together with R01 LP, R01 Capital and the Reporting Person, the &quot;R01 Entities&quot;), each of which or whom disclaim beneficial ownership of these shares, except to the extent of its or his pecuniary interest in such shares, if any.

        <footnote id="F3">This amendment updates the beneficial ownership of the Reporting Persons to reflect anti-dilution adjustments under the pre-funded warrants issued by the Issuer to R01 LP and other investors on October 16, 2025 (the &quot;Pre-Funded Warrants&quot;). As a result of dilutive issuances of the Issuer's Common Stock during the fourth quarter of 2025, the anti-dilution adjustments of the Pre-Funded Warrants increased the Reporting Person's aggregate number of shares of Common Stock issuable upon exercise of the Pre-Funded Warrants to 56,660,098 on a pre-Reverse Stock Split basis, which was adjusted to 11,332,020 on a post-Reverse Stock Split basis..</footnote>
        <footnote id="F4">The Pre-Funded Warrants have no expiration date and are exercisable for shares of Common Stock at any time.</footnote>
