As of the close of business on August 20, 2026, the record date for the Extraordinary General Meeting (the “Record Date”), there were 23,710,000 Class A ordinary shares, par value $0.0001 per share (the “SPAC Class A Shares”), and 7,880,000 Class B ordinary shares, par value $0.0001 per share (the “SPAC Class B Shares” and, together with the SPAC Class A Shares, the “SPAC Common Shares”), of the Company issued and outstanding and entitled to vote. A total of 21,877,045 SPAC Common Shares, representing approximately 69% of the SPAC Common Shares entitled to vote and constituting a quorum, were represented in person (including virtually) or by proxy at the Extraordinary General Meeting.

Each of the proposals is described in more detail in the Company’s definitive proxy statement/prospectus filed with the U.S. Securities and Exchange Commission on August 27, 2026 (the “Proxy Statement/Prospectus”).
