On November 24, 2025, AI Infrastructure Acquisition Corp. (the “Company”) announced that, commencing on November 24, 2025, the holders of the units issued in its initial public offering (the “Units”), each Unit consisting of one Class A ordinary share, par value $0.0001 per share (the “Class A Ordinary Shares”), and one right to receive one-fifth (1/5) of one Class A Ordinary Share upon the consummation of the Company’s initial business combination (the “Rights”), may elect to separately trade the Class A Ordinary Shares and the Rights included in the Units.

The Class A Ordinary Shares and the Rights now trade on the New York Stock Exchange under the symbols “AIIA” and “AIIA R”, respectively. Any Units not separated will continue to trade on the New York Stock Exchange under the symbol “AIIA U”. Holders of Units will need to have their brokers contact the Company’s transfer agent, Odyssey Transfer and Trust Company, in order to separate the Units into Class A Ordinary Shares and Rights.

On November 24, 2025, the Company issued a press release announcing the separate trading of the Class A Ordinary Shares and Rights underlying the Units, a copy of which is attached as Exhibit 99.1 to this Current Report on Form 8-K.
