(1)	On April 21, 2023, the Issuer announced that its board of directors had determined to redeem all of its outstanding shares of Class A common stock sold in the Issuer’s initial public offering (the “Public Shares”), effective as of May 4, 2023, because the Issuer will not be able to consummate an initial business combination within the time period required by its amended and restated certificate of incorporation. As of the close of business on May 4, 2023, the Public Shares were deemed cancelled and represented only the rights to receive the per-share redemption price. In connection with the redemption of the Public Shares and anticipated dissolution of the Issuer, on May 4, 2023, B. Riley Principal 250 Sponsor Co., LLC (the “Sponsor”) forfeited to the Issuer for no consideration 4,312,499 shares of Class B common stock and 600,000 shares of Class A common stock. By their terms, the 200,000 private placement warrants held by the Sponsor expired worthless. In connection with the dissolution of the Issuer, on June 2, 2023, the Sponsor surrendered to the Issuer one share of Class B common stock.

(2)	Prior to their surrender and expiration, the securities were held directly by the Sponsor. B. Riley Principal Investments, LLC (“BRPI”) is the sole member of the Sponsor and is a wholly-owned subsidiary of B. Riley Financial, Inc. (“BRF”). BRPI and BRF have voting and dispositive power over securities held by the Sponsor. Bryant R. Riley is the Co-Chief Executive Officer and Chairman of the Board of Directors of BRF. As a result, each of BRPI, BRF and Bryant R. Riley may be deemed to have indirectly beneficially owned the securities directly held by the Sponsor. Each of BRPI, BRF and Bryant R. Riley disclaimed beneficial ownership over the securities directly held by the Sponsor other than to the extent of its/his respective pecuniary interest therein, directly or indirectly.

On April 21, 2023, the Issuer announced that its board of directors had determined to redeem all of its outstanding Public Shares, effective as of May 4, 2023, because the Issuer will not be able to consummate an initial business combination within the time period required by its amended and restated certificate of incorporation.

By their terms, the 200,000 warrants held by the Sponsor expired worthless. In connection with the dissolution of the Issuer, on June 2, 2023, the Sponsor surrendered to the Issuer one share of Class B common stock.
