        <footnote id="F1">Mr. Bradley, as an officer and member of the board of directors of EOS Technology Holdings Inc. (&quot;EOS&quot;), may be deemed to share voting and investment power over shares of common stock beneficially owned by EOS. Pursuant to a Letter Agreement dated July 29, 2026, EOS may elect to receive shares of Common Stock in lieu of cash in satisfaction of a quarterly earnout payment obligation owed by the issuer to EOS. If EOS subsequently distributes any such shares to its shareholders, the number of shares reported herein as indirectly beneficially owned by Mr. Bradley through EOS would decrease to reflect the reduction in EOS's holdings. Such a decrease would result from the distribution by EOS and would not necessarily indicate that Mr. Bradley sold shares in an open market transaction.</footnote>
        <footnote id="F2">Mr. Bradley disclaims beneficial ownership of these securities except to the extent of his pecuniary interest therein, and the inclusion of these securities in this report shall not be deemed an admission of beneficial ownership for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or otherwise.</footnote>
