HCM IV Acquisition Corp.

HCM IV Acquisition Corp. is a blank check company incorporated as a Cayman Islands exempted corporation on September 5, 2025. The company was formed to complete a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization, or similar business combination with one or more businesses. On October 29, 2025, the company changed its name from Mercator I Acquisition Corp. It has not yet selected a specific business combination target and has not initiated any substantive discussions with potential targets. While the company may pursue a target in any business, industry, or stage of corporate evolution, its primary focus is on established businesses of scale that are positioned for continued growth and led by highly regarded management teams. On September 5, 2025, the Sponsor contributed $25,000, or approximately $0.003 per share, and received 8,433,333 founder shares. Through a share recapitalization on November 3, 2025, the company issued an additional 191,667 Class B ordinary shares to the Sponsor, resulting in the Sponsor holding 8,625,000 founder shares at approximately $0.003 per share. Initially, up to 1,125,000 of these founder shares were subject to forfeiture based on the underwriters' over-allotment exercise. However, on February 13, 2026, the underwriters exercised their over-allotment option in full as part of the closing of the Initial Public Offering, meaning these 1,125,000 founder shares are no longer subject to forfeiture.
