Separate Trading of Class A Ordinary Shares and Warrants

On March 25, 2026, Colombier Acquisition Corp. III (the “Company”) announced that, commencing on March 27, 2026, the holders of the units issued in its initial public offering (the “Units”), each Unit consisting of one Class A ordinary share of the Company, par value $0.0001 per share (the “Class A Ordinary Share”), and one-eighth of one warrant of the Company (the “Warrant”), with each whole Warrant entitling the holder thereof to purchase one Class A Ordinary Share for $11.50 per share, may elect to separately trade the Class A Ordinary Shares and the Warrants included in the Units. No fractional Warrants will be issued upon separation of the Units and only whole Warrants will trade. The Class A Ordinary Shares and the Warrants are expected to trade on the New York Stock Exchange under the symbols “CLBR” and “CLBR WS,” respectively. Holders of Units will need to have their brokers contact Continental Stock Transfer & Trust Company, the Company’s transfer agent, in order to separate the Units into Class A Ordinary Shares and Warrants.
