The Class B Ordinary Shares are convertible into shares of the Issuer's Class A Ordinary Shares on a one-for-one basis, subject to adjustment pursuant to certain anti-dilution rights, and have no expiration date.

The Class B Ordinary Shares owned by CH4 Natural Solutions Acquisition Sponsor LLC (the "Sponsor") included up to 1,000,000 shares that were subject to forfeiture in the event the underwriters of the initial public offering of the Issuer's securities did not exercise their over-allotment option in full as described in the Issuer's Registration Statement on Form S-1 (File No. 333-284199). Because the underwriters exercised their over-allotment option in part and the remainder of the option expired, the Sponsor automatically forfeited 333,333 Class B Ordinary Shares on June 15, 2026 for cancellation by the Issuer.
