EXPLANATORY NOTE

On February 17, 2026, T3 Defense Inc., a Delaware corporation (the “Company”), filed a Current Report on Form 8-K (the “Initial 8-K”) with the Securities and Exchange Commission (the “SEC”) to disclose that it had completed its acquisition of 51% of the outstanding equity capital of I.T.S. Industrial Tecno-logic Solutions Ltd. (“ITS”) on a fully diluted basis, pursuant to the previously disclosed Agreement, dated June 8, 2025, among Star Twenty Six Ltd., ITS and its controlling shareholder Gera Eron. This amendment to the Initial 8-K (this “Amendment”) amends the Initial 8-K to include the historical audited financial statements of ITS and the pro forma combined financial information required by Items 9.01(a) and 9.01(b) of Form 8-K that were excluded from the Initial 8-K in reliance on the instructions to such items.

This Amendment No. 1 should be read in conjunction with the Initial 8-K. Except as set forth herein, no modifications have been made to information contained in the Initial 8-K, and the Company has not updated any information contained therein to reflect events that have occurred since the date of the Initial 8-K. The pro forma financial information included as Exhibit 99.2 to this Amendment No. 1 has been presented for informational purposes only, as required by Form 8-K, and is not necessarily indicative of the financial position or results of operations that would have been realized if the Acquisition had been completed on the dates set forth therein, nor is it indicative of the future results or financial position of the combined company.

Forward-Looking Statements

This Amendment No. 1 may include forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and the provisions of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and other related laws, which relate to future events and are subject to risks and uncertainties. The forward-looking statements, which address the Company’s expected business and financial performance and financial condition, among other matters, may contain words and terms such as: “believe,” “could,” “estimate,” “expect,” “may,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “will,” or “would” and other words and terms of similar meaning. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about expected earnings, revenues, growth, liquidity, and other matters. A further description of these uncertainties and other risks can be found in the Company’s filings with the Securities and Exchange Commission. These or other uncertainties could cause the Company’s actual future results to be materially different from those expressed in any forward-looking statements. The Company undertakes no obligation to update or revise any forward-looking statements except as required by law.

Item 9.01. Financial Statements and Exhibits.
