Item 8.01

Other Events

Separate Trading of Units, Ordinary Shares and Warrants

As previously reported on May 22, 2025, Armada Acquisition Corp. II, a Cayman Islands exempted company (the “Company”), consummated its initial public offering of 23,000,000 units (the “Units”). Each Unit consists of one Class A ordinary share of the Company, par value $0.0001 per share (“Ordinary Shares”), and one-half of one redeemable warrant of the Company (“Warrant”), with each whole Warrant entitling the holder thereof to purchase one Ordinary Share for $11.50 per share. The Units were sold at a price of $10.00 per Unit, generating gross proceeds to the Company of $230,000,000.

On June 17, 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 Ordinary Shares and the Warrants comprising the Units separately commencing on June 24, 2025. Those Units not separated will continue to trade on the Nasdaq Stock Market LLC (“Nasdaq”) under the symbol “AACIU,” and the Ordinary Shares and Warrants that are separated will trade on the Nasdaq under the symbols “AACI” and “AACIW,” 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 Ordinary Shares and Warrants.
