Explanation of Responses:

1. As described in the Issuer's registration statement on Form S-1 (File No. 333-254513) under the heading "Description of Securities--Founder Shares", the Class B ordinary shares will automatically convert into shares of Class A ordinary shares at the time of the issuer's initial business combination, on a one-for-one basis, subject to certain adjustments described therein and have no expiration date.

2. These Class B ordinary shares are held by Coliseum Acquisition Sponsor LLC (the "Sponsor") acquired pursuant to a subscription agreement by and between the Sponsor and the Issuer. The Class B ordinary shares owned by the Sponsor includes up to 562,500 shares that are subject to forfeiture in the event the underwriters of the Issuer's initial public offering do not exercise in full their over-allotment option as described in the issuer's registration statement.

3. Reporting Person is the Co-Chief Executive Officer and Director of the Issuer, and is a managing member of the Sponsor. Reporting Person has voting and investment discretion with respect to the securities held by the Sponsor. As such, Reporting Person may be deemed to share beneficial ownership of the shares of Class B ordinary shares held directly by the Sponsor. Reporting Person disclaims any beneficial ownership of the reported shares other than to the extent of any pecuniary interest he may have therein, directly or indirectly.
