Each Unit consists of one Class A ordinary share, $0.0001 par value (“Class A Ordinary Share”) and one-half of one redeemable warrant of the Company (each, a “Warrant”), with each whole Warrant entitling the holder thereof to purchase one Class A Ordinary Share at a price of $11.50 per share (subject to adjustment).

On September 16, 2025, the Company issued a press release, a copy of which is attached as Exhibit 99.1 to this Current Report on Form 8-K, announcing that the holders of the Units may elect to trade Class A Ordinary Shares and the Warrants comprising the Units separately commencing on September 19, 2025. Those Units not separated will continue to trade on the Nasdaq Global Market (“Nasdaq”) under the symbol “KOYNU,” and the Class A Ordinary Shares and Warrants that are separated will trade on the Nasdaq under the symbols “KOYN” and “KOYNW,” respectively. No fractional Warrants will be issued upon separation of the Units and only whole Warrants will trade. Holders of the Units will need to instruct their brokers to contact Continental Stock Transfer & Trust Company, the Company’s transfer agent, to separate their Units into Class A Ordinary Shares and Warrants.
