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 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 an established business of scale poised for continued growth, led by a highly regarded management team. On September 5, 2025, the Sponsor made a capital contribution of $25,000, or approximately $0.003 per share, and received 8,433,333 founder shares. On November 3, 2025, the company issued an additional 191,667 Class B ordinary shares to the Sponsor through a share recapitalization, resulting in the Sponsor holding 8,625,000 founder shares at approximately $0.003 per share. Up to 1,125,000 of these founder shares were initially 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.
