Item 1 Comment:

This Amendment No. 1B (this "Amendment") amends and supplements the Schedule 13D filed with the United States Securities and Exchange Commission (the "SEC") on August 22, 2025 (the "Original Schedule 13D") by Cantor EP Holdings IV, LLC, a Delaware limited liability company (the "Sponsor"), Cantor Fitzgerald, L.P., a Delaware limited partnership ("Cantor"), CF Group Management, Inc., a New York corporation ("CFGM") and Howard W. Lutnick, and Amendment No. 1A to the Original Schedule 13D, dated October 6, 2025, filed by the Sponsor, Cantor, CFGM and Brandon G. Lutnick, relating to their beneficial ownership of Class A ordinary shares, par value $0.0001 per share, of the Issuer ("Class A Ordinary Shares") and Class B ordinary shares, par value $0.0001 per share, of the Issuer ("Class B Ordinary Shares" and, together with the Class A Ordinary Shares, the "Ordinary Shares"). Capitalized terms used but not defined in this Amendment have the respective meanings set forth in the Original Schedule 13D. This Amendment No. 1B is being filed solely by Howard W. Lutnick to indicate that he no longer has any voting or dispositive power of the securities of the Issuer and therefore shall cease to be a Reporting Person.

The sale of such interests was completed on October 6, 2025, and as a result, Mr. Howard W.
