Item 1.01

Entry into a Material Definitive Agreement.

Sponsor Securities Purchase Agreement

On August 12, 2025, Armada Acquisition Corp. II, a Cayman Islands exempted Company (the “Company”), entered into a Sponsor Securities Purchase Agreement (the “Agreement”) with Armada Sponsor II LLC, a Delaware limited liability company (the “Sponsor”), and Arrington XRP Capital Fund, LP, a Delaware limited partnership (the “Acquiror”), pursuant to which the Sponsor agreed to sell to the Acquiror, and the Acquiror agreed to purchase from the Sponsor, an aggregate of 7,880,000 Class B ordinary shares, par value $0.0001 per share, 400,000 Class A ordinary shares, par value $0.0001 per share, and 200,000 private placement warrants of the Company for an aggregate purchase price of $6,600,000.

The Agreement contains customary representations, warranties and covenants of the parties. The representations, warranties and covenants of each party set forth in the Agreement were made solely for the benefit of the other parties to the Agreement, and shareholders of the Company are not third-party beneficiaries of those representations, warranties and covenants. In addition, the representations, warranties and covenants (a) were subject to materiality and other qualifications contained in the Agreement, which may differ from what may be viewed as material by shareholders of the Company, (b) were made only as of the date of the Agreement or such other date as is specified in the Agreement and (c) may have been included in the Agreement for the purpose of allocating risk between the parties rather than establishing matters as facts. Accordingly, the Agreement is included with this filing only to provide shareholders of the Company with information regarding the terms of the Agreement, and not to provide shareholders of the Company with any other factual information regarding any of the parties or their respective businesses.

The closing of the transactions contemplated by this Agreement is expected to occur no later than September 15, 2025, subject to satisfaction of the conditions set forth in the Agreement. Upon closing, the Acquiror will become the Company’s sponsor.

Following the closing, Stephen P. Herbert and Douglas M. Lurio are expected to be advisors to the new Chief Executive Officer of the Company to be appointed at closing.

The above description of the Agreement is qualified in its entirety by reference to the full text of the Agreement, which is incorporated by reference herein and attached hereto as Exhibit 10.1.
