        <footnote id="F1">Each share of Class C Common Stock is convertible into one share of Class A Common Stock at the holder's option upon written notice, subject to Article 4, Sections 4 and 11 of the Issuer's Amended and Restated Articles of Incorporation. Those provisions include the restriction on the SBI Group Ownership Percentage, as defined in the Articles, exceeding 39.9%. Class C Common Stock also converts automatically upon a Transfer, as defined in the Articles, unless the conversion would cause either applicable ownership limit in Article 4, Section 4(b) to be exceeded. The underlying Class A shares reported in Table II are not included in Table I.</footnote>
        <footnote id="F2">The Reporting Person directly holds 1,633,180 shares of Class C Common Stock. No additional consideration is payable upon conversion, and the Class C Common Stock has no expiration date. Reporting the underlying shares does not imply that conversion is presently permitted without regard to the restrictions described in note (1).</footnote>

The holdings reported herein reflect the Reporting Person's holdings as of October 9, 2026, the date of completion of the Issuer's business combination.
