**EXPLANATORY NOTE**

On February 25, 2026, T3 Defense Inc. (the "Company") filed a Current Report on Form 8-K (the "Original Form 8-K") disclosing the execution and delivery of a Securities Purchase Agreement in connection with a private placement consisting of 400 units for an aggregate purchase price of $20,000,000, or a per unit price of $50,000. Each unit consists of (i) one share of Series B Convertible Preferred Stock, par value $0.0001 per share, and (ii) one and a half common stock purchase warrants to initially purchase up to one and a half shares of common stock, par value $0.0001 per share, of the Company, subject to adjustment as described herein (the "Common Warrants").

**Item 1.01 Entry into a Material Definitive Agreement.**

The Original Form 8-K contained a typographical error with respect to the exercise price of the Common Warrants. Each Common Warrant will be initially exercisable for one share of Common Stock at an initial exercise price of $2.13 per share, subject to adjustment for stock splits, distributions and the like. The Original Form 8-K inadvertently disclosed an incorrect exercise price.

Except as described above, no other changes have been made to the Original Form 8-K, and this amendment does not modify or update any other information contained in the Original Form 8-K. This amendment should be read in conjunction with the Original Form 8-K.

**SIGNATURE**

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
