Item 8.01 Other Events.

On February 19, 2026 Armada Acquisition Corp. III (the “Company”) consummated its initial public offering (the “IPO”) of 24,850,000 units (the “Units”), including 2,350,000 units issued pursuant to the partial exercise of the underwriters’ over-allotment option. Each Unit consists of one Class A ordinary share of the Company, par value $0.0001 per share (each, an “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 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 $248,500,000.

On February 19, 2026 simultaneously with the consummation of the IPO, the Company completed the private sale (the “Private Placement”) of an aggregate of 672,000 private placement units (the “Private Placement Units”) to Armada Sponsor III LLC, the Company’s sponsor (the “Sponsor”), Cohen & Company Capital Markets, a division of Cohen & Company Securities, LLC, and Northland Securities, Inc. at a purchase price of $10.00 per Private Placement Unit, generating gross proceeds to the Company of $6,720,000.

A total of $248,500,000 out of the proceeds from the IPO and the sales of the Private Placement Units was placed in a U. S.-based trust account maintained by Continental Stock Transfer & Trust Company, acting as trustee.

An audited balance sheet as of February 19, 2026 reflecting the receipt of the proceeds upon the consummation of the IPO and the Private Placement has been issued by the Company and is included as Exhibit 99.1 to this Current Report on Form 8-K.

As a result of the underwriters’ partial exercise and forfeiture of the unexercised portion of the over-allotment option, the Sponsor forfeited 345,083 Class B ordinary shares of the Company, par value $0.0001 per share (the “Class B Ordinary Shares”), resulting in the Sponsor holding an aggregate of 8,252,834 Class B Ordinary Shares.
