Jae Hyun (James) Park, 59, is an investment professional and executive with extensive experience in cross-border capital markets, SPAC transactions, and natural resources investments. Mr. Park currently serves as Executive Chairman of Keystone Acquisition Corp., a special purpose acquisition company established in the Cayman Islands in November 2025, where he leads sponsor activities, capital formation, and strategic execution of the company’s business combination objectives. He is also the Managing Member of Keystone International Acquisition Management LLC, a Delaware-based entity formed in November 2025 that manages and operates the sponsor activities of Keystone Acquisition Corp.

On April 24, 2026, the Company entered into a letter agreement with Mr. Park (the “Letter Agreement”) on substantially the same terms as the form of letter agreement previously entered into by and between the Company and each of its other directors in connection with the Company’s initial public offering.
