Item 3.01 Notice of Delisting or Failure

to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On May 5, 2026, T3 Defense

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

LLC ("Nasdaq") that it is not in compliance with the minimum bid requirements set forth in Nasdaq Listing Rule 5550(a)(2) for

continued listing on The Nasdaq Global Market. Nasdaq Listing Rule 5550(a)(2) requires listed securities to maintain a minimum bid

price of $1.00 per share, and Nasdaq Listing Rule 5810(c)(3)(A) provides that a failure to meet the minimum bid price requirement

exists if the deficiency continues for a period of 30 consecutive business days. Based on the closing bid price of the Company’s

common stock between March 23, 2026 to May 4, 2026, the Company no longer meets the minimum bid price requirement. The Notification

Letter has no immediate effect on the listing or trading of the Company’s common stock on The Nasdaq Global Market and, at

this time, the common stock will continue to trade on The Nasdaq Global Market under the symbol “DFNS.”

The Notification Letter

provides that the Company has 180 calendar days, or until November 2, 2026, to regain compliance with Nasdaq Listing Rule 5550(a)(2).

To regain compliance, the bid price of the Company's common stock must have a closing bid price of at least $1.00 per share for a minimum

of 10 consecutive business days. If the Company does not regain compliance by November 2, 2026, the Company may be eligible for additional

time to regain compliance. In such instance, the Company must submit an application and a non-refundable $5,000 application fee, so long

as the Company meets The Nasdaq Global Market continued listing requirements (except for the bid price requirement) and notifies Nasdaq in

writing of its intention to cure the deficiency during the second compliance period. If the Company does not qualify or fails to regain

compliance, then Nasdaq will notify the Company of its determination to delist the Company's common stock.

The Company intends to

monitor the closing bid price of its common stock and may, if appropriate, consider implementing available options, including, but not

limited to, implementing a reverse stock split of its outstanding securities, to regain compliance with the minimum bid price requirement

under the Nasdaq Listing Rules.
