        <footnote id="F1">This amendment is being filed to correct an inadvertent typographical error in Table I of the original Form 4, filed August 25, 2026, in which the ownership form codes were incorrectly listed as &quot;Disposed Of (D),&quot; rather than &quot;Securities Acquired (A).&quot; This amendment corrects such detail in Table I to reflect the acquisition of securities.</footnote>
        <footnote id="F2">This amendment is also being filed to correct the Amount of Securities Beneficially owned by the Reporting Person previously reported on the Form 4 filed on August 25, 2026. Due to an administrative error, the original filing incorrectly reported that 13,442 shares were beneficially owned following the transaction being reported. The correct number of shares beneficially owned, as reported in this amendment, was 65,942 shares.</footnote>
