MTNE · CH4 Natural Solutions Corporation

CH4 Natural Solutions Corporation, a Cayman Islands blank check company sponsored by affiliates of Riverstone Earth LLC, successfully closed its upsized IPO on May 4, 2026, raising $200 million in gross proceeds from 20 million units at $10 per unit underwritten by Santander US Capital Markets LLC. Concurrently, the company sold 200,000 private placement units to CH4 Natural Solutions Acquisition Security Holdings, LLC at the same price, generating $2 million. Of the net proceeds, $200 million—including $6 million in deferred underwriting discounts—has been deposited into a U.S. trust account managed by Continental Stock Transfer & Trust Company, to be released only upon initial business combination, shareholder redemption related to amendments, or liquidation after 24 months. Key agreements executed include the underwriting agreement, public and private warrant agreements (warrants exercisable at $11.50 per Class A share post-business combination), letter agreement imposing transfer restrictions and voting commitments on insiders, trust agreement, registration rights, and administrative support with a sponsor affiliate at $10,000 monthly. The Amended and Restated Memorandum and Articles, filed as Exhibit 3.1, govern share classes, redemption rights, and business combination requirements targeting real-asset businesses for methane mitigation. Board appointments of five directors, three independent (Nate Zwald, Ben Veres, Jeffrey Tepper), establish NYSE-compliant committees with indemnification agreements. Underwriters hold a 45-day over-allotment option for 3 million additional units. This structure positions the SPAC with significant dry powder for a business combination within 24 months, listed on NYSE under MTNE.U.
