        <footnote id="F1">On October 21, 2026, the reporting person was awarded 12,000 RSUs under the Issuer's 2026 Stock Incentive Plan. The RSUs vest in full on January 9, 2027 (the &quot;Vesting Date&quot;), subject to the reporting person's continued service through such date. Upon vesting and settlement, the reporting person will receive a number of shares of common stock equal to the number of RSUs that have vested.</footnote>
        <footnote id="F2">An aggregate of 6,681 of the 7,100 previously reported RSUs awarded under the Issuer's 2024 Stock Incentive Plan will vest on the Vesting Date, subject to the Reporting Person's continued service through such date, and settle for shares of common stock equal to the number of RSUs that have vested. The remaining 419 previously reported RSUs will not vest and will be forfeited. Accordingly, the amount of securities beneficially owned directly in column 5 of Table 1 reflects the forfeiture.</footnote>
        <footnote id="F3">On April 28, 2026, the Issuer effected a one-for-20 reverse stock split of its issued and outstanding common stock and made proportionate retroactive adjustments to its outstanding equity awards to the extent required including with respect to then-outstanding RSUs (the &quot;Reverse Split&quot;). No fractional shares were issued in connection with the Reverse Split, and each holder who otherwise would have been entitled to receive a fractional share received one whole share of common stock in lieu of such fractional share. Accordingly, the amount of securities beneficially owned directly and indirectly in column 5 of Table 1 has been adjusted to reflect the impact of the Reverse Split.</footnote>
