[1] On September 30, 2025, the Sponsor forfeited 825,000 Founder Shares, and Maxim and certain third-party investors purchased an aggregate of 825,000 Founder Shares for approximately $0.013 per share. The foregoing transactions did not result in a change in the number of Class B ordinary shares outstanding. All share and per share information has been retrospectively presented (see Note 5).
[2] Weighted average shares for the 2025 periods exclude an aggregate of up to 250,000 Class B ordinary shares subject to forfeiture if the over-allotment option was not exercised in full or in part by the underwriters (Note 6). On October 1, 2025, the underwriters fully exercised their over-allotment option in connection with the Company's Initial Public Offering. As such, no Class B ordinary shares were forfeited, and the full 1,916,667 Class B ordinary shares are reflected in the 2026 periods.
