Cayson Acquisition Corp (CAPN) is a special purpose acquisition company that filed an amended Form F-4/A registration statement with the U.S. Securities and Exchange Commission on July 31, 2026, signaling active progress toward a business combination. The use of Form F-4, typically reserved for transactions in which a foreign private issuer is a party, indicates the proposed merger target or resulting entity is incorporated or domiciled outside the United States. The amendment filing places CAPN in the de-SPAC execution phase, as the company continues working through regulatory review ahead of a shareholder vote and anticipated close.
