On August 17, 2026, T3

Defense Inc., a Delaware corporation (the “Company”) received a written notice (the “Notice”) from The Nasdaq

Stock Market, LLC ("Nasdaq") that it regained compliance with the minimum bid price as required by Listing Rule 5450(a)(1).

As previously disclosed

on a Current Report on Form 8-K filed by the Company with the Securities and Exchange Commission on May 8, 2026, Nasdaq had notified the

Company that its Common Stock failed to maintain a minimum bid price of $1.00 over the previous 30 consecutive business days as required

by the Listing Rules of The Nasdaq Stock Market. Since then, Nasdaq determined that for the last 10 consecutive business days, from August

3, 2026 to August 14, 2026, the closing bid price of the Company’s Common Stock has been at $1.00 per share or greater.

As a result, the Company believes that it is in compliance with all

applicable listing requirements.

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.
