Item 1.01. Entry into a Material Definitive Agreement.

Private Placement

On February 24, 2026, T3 Defense Inc. (the “Company”) entered into a Securities Purchase Agreement with an accredited investor (the “Securities Purchase Agreement”) for a private placement (the “Private Placement”) pursuant to which the investor (the “Purchaser”) agreed to purchase from the Company 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 (each a “Share” and collectively, the “Shares”) of Series B Convertible Preferred Stock, par value $0.0001 per share (the “Series B Preferred Stock”), 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 (the “Common Stock”), of the Company, subject to adjustment as described herein (the “Common Warrants” and the shares of Common Stock issuable upon exercise or exchange of the Common Warrants, the “Warrant Shares”). The Private Placement Offering is scheduled to close on or about Thursday, February 26, 2026.

The Private Placement is structured as a two stage investment. At the initial closing, which is scheduled to occur on February 26, 2026, the Company will sell 200 units for gross proceeds of $10 million. The Purchaser agreed to purchase an additional 200 units for an additional investment of $10 million following (i) the effectiveness of the registration statement described below, (ii) stockholder approval of the issuance of the transactions contemplated by the Securities Purchase Agreement as required pursuant to Nasdaq rules, (iii) the stock price is at least $1.00 and (iv) subject to the condition that the value of the trading in the Company’s stock on Nasdaq for the 10 consecutive days preceding the second closing is at or above $900,000 (the “Second Closing Market Trading Value”), provided that if the Second Closing Market Trading Value is less than $900,000, then there will be a proportionate reduction in the number of units to be sold at the second closing. By way of illustration only, if the Second Closing Market Trading Value during the ten consecutive trading days immediately prior to the second closing date is at least $450,000, then the closing on said date shall be for $5,000,000 of units. Additional closings of units will occur when the market trading value for ten consecutive trading days is at or above $900,000.

Securities Purchase Agreement

Pursuant to the Securities Purchase Agreement, the Company is required to seek stockholder approval (the “Stockholder Approval”) related to the issuance of the units to be issued in the Private Placement. The Company is required to file a preliminary proxy statement for a special meeting of the Company’s stockholders within 75 days of the initial closing of the Private Placement. The Company’s directors and officers have agreed to execute voting agreements to vote in favor of the applicable proposals. If the Company does not obtain Stockholder Approval at the first such meeting, the Company is required to call a meeting every 4 months thereafter to seek Stockholder Approval until the earlier of the date on which Stockholder Approval is obtained or the securities are no longer outstanding.

The Company has also granted the Purchaser a right of participation in subsequent financings of the Company for a period of time following closing, subject to certain exempt issuances, and has agreed not to issue securities for a period of time following the closing of the Private Placement, subject to certain exempt issuances, including issuances pursuant to strategic transactions.

Under the terms of the Securities Purchase Agreement, the Company agreed not deliver any purchase notices under Company’s equity line of credit with the Purchaser until after the later of the date on which (i) the registration statement is declared effective and (ii) the Company obtains Stockholder Approval and even after such date, certain market conditions must be satisfied.

The Company’s chief executive officer and directors have entered into a standard lock up agreement with respect to 75% of their holdings for the period from the initial closing through the third month following the effectiveness of the registration statement.

The Securities Purchase Agreement contains customary representations, warranties and agreements of the Company and the Purchaser and customary indemnification rights and obligations of the parties thereto.

Series B Preferred Stock

The Series B Preferred Stock will be issued at closing of the Private Placement pursuant to the Certificate of Designations of Rights, Preferences and Limitations to be filed with the Secretary of State of the State of Delaware prior to closing of the Private Placement. Pursuant to the terms of said Certificate, each share of Series B Preferred Stock has a stated value of $50,000 (the “Stated Value”) and will initially be convertible into 23,474 shares of Common Stock (the “Conversion Shares”) (or pre-funded warrants in lieu thereof (the “Pre-Funded Warrants”)), calculated by dividing the Stated Value by the initial conversion price equal to $2.13 per Share (the “Initial Conversion Price”). The Initial Conversion Price is subject to adjustment upon stock splits, distributions, reorganizations, reclassifications, change of control and the like, and is also subject to price-based anti-dilution adjustments for subsequent offerings made by the Company while the Series B Preferred Stock remains outstanding (subject to certain exempt issuances). The Initial Conversion Price will also be adjusted upon receipt of Stockholder Approval (as hereinafter defined), if obtained, to the lower of (i) the then applicable conversion price and (ii) the price per share of the Common Stock on its trading market upon the earlier of (A) effectiveness of the registration statement required to be filed pursuant to the Registration Rights Agreement (as defined herein) or (B) upon applicability of Rule 144 as it relates to the sale of the Conversion Shares.

The Series B Preferred Stock is convertible at the option of the holder at any time and will be automatically converted into Common Stock or Pre-Funded Warrants in lieu thereof on the effective date of the registration statement, whether or not the Stockholder Approval has been obtained. If at any time after the one-year anniversary of the closing of the Private Placement, the Series B Preferred Stock is then outstanding and the Company has not received Stockholder Approval, the Series B Preferred Stock is redeemable at the option of the holder at a price per Share equal to 105% of the Stated Value. The conversion of the Series B Preferred Stock is subject to a 9.9% beneficial ownership limitation blocker.

The Series B Preferred Stock are not entitled to receive dividends, other than on an as-converted basis if dividends are paid to holders of Common Stock.

The holders of Series B Preferred Stock are entitled to 10,000 votes per each share of Series B Preferred Stock. The holders of Series BPreferred Stock have voting rights with respect to certain corporate actions that affect the rights of the Series B Preferred Stockholders and also have certain consent rights in connection with certain proposed Fundamental Transactions (as defined in the Certificate of Designations).

The Series B Preferred Stock is (i) senior to the Common Stock of the Company and any other equity securities that the Company may issue in the future, the terms of which specifically provide that such equity securities rank junior to the Series B Preferred Stock, (ii) equal with any class or series of capital stock established after the closing date of the Private Placement, the terms of which specifically provide that such equity securities rank on par with such Series B Preferred Stock, in each case with respect to payment of amounts upon liquidation, dissolution or winding up and (iii) junior to all of the Company’s existing and future indebtedness. The Company has agreed not to issue any parity stock or senior securities without the written consent of a majority in interest of the Series B Preferred Stock. Upon a change of control, liquidation or winding up of the Company the holders of the Series B Preferred Stock are entitled to a liquidation preference of $50,000 per Share.

Common Warrants

The Common Warrants are exercisable on a cash or cashless basis at the earlier of (i) 180 days following their issuance and (ii) the date the stockholder approval is obtained, and expire 5 years from the date of issuance. Each Common Warrant will be initially exercisable for one share of Common Stock at an initial exercise price of $0.0125 per share, subject to adjustment for stock splits, distributions and the like (the “Initial Exercise Price”). The Initial Exercise Price is also subject to price-based anti-dilution adjustments for subsequent offerings made by the Company while the Common Warrants remain outstanding (subject to certain exempt issuances). At any time after the closing of the Private Placement, the holder of the Common Warrants may exchange the Common Warrants on a cashless basis for a number of shares of Common Stock determined by multiplying the total number of Warrant Shares with respect to which the Common Warrant is then being exercised by the Black Scholes Value (as defined in the Common Warrant) divided by the lower of the two closing bid prices of the Common Stock in the two days prior the time of such exercise, but in any event not less than $0.01 (as may be adjusted for stock dividends, subdivisions, or combinations and the like). The exercise of the Common Warrants is subject to a 9.9% beneficial ownership limitation blocker.

In the event of a Fundamental Transaction (as defined in the Common Warrants), the holders of the Common Warrants will be entitled to receive upon exercise of the Common Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Common Warrants immediately prior to such Fundamental Transaction. Additionally, as more fully described in the Common Warrants, the holders of the Common Warrants will be entitled to receive consideration in an amount equal to the Black Scholes value of the Common Warrant in connection with a Fundamental Transaction.

If the Company fails to timely deliver the Warrant Shares issuable upon exercise of the Common Warrants, the Company will be subject to liquidated damages, payable in the Company’s discretion in cash or shares on the Registration Date (as defined therein) or buy-in. If the Company elects to pay in shares, the number of shares due will be based on the LD Share Formula (as defined below).

Registration Rights Agreement

In connection with the Private Placement, on February 24, 2026, the Company and the Purchaser entered into a Registration Rights Agreement (the “Registration Rights Agreement”). Pursuant to the terms of the Registration Rights Agreement, the Company is required to register the resale of the Conversion Shares (and any shares underlying the Pre-Funded Warrants, if any) and the Warrant Shares. The Company is required to prepare and file an initial registration statement (the “Initial Registration Statement”) with the Securities and Exchange Commission within 45 days of the date of the Securities Purchase Agreement (the “Filing Deadline”) and to use commercially reasonable efforts to have the Initial Registration Statement declared effective within 75 days of the date of the Securities Purchase Agreement (the “Effectiveness Deadline”). In certain circumstances including, but not limited to, if the Company misses the Filing Deadline or the Effectiveness Deadline, then the Company will be required to pay to the Purchasers an amount in shares or cash, at the Company’s discretion, as partial liquidated damages and not as a penalty, equal to the product of 1.5% multiplied by the aggregate purchase price paid by such Purchaser. Liquidated damages, if any, will accrue and be paid on the earlier of the effective date of a resale registration statement registering the sale of the shares that may be issued in lieu of cash or the date on which such shares can be sold pursuant to Rule 144 (the “Registration Date”). If the Company elects to pay liquidated damages in shares of Common Stock, the number of shares of Common Stock issuable to the Purchaser will be determined by dividing the aggregate amount of accrued liquidated damages by the closing price of the Company’s Common Stock on the trading market of the Common Stock on the day immediately prior to the Registration Date (the “LD Share Formula”).

Placement Agency Agreement

In connection with the Private Placement, the Company entered into a Placement Agency Agreement, dated February 24, 2026, with Dawson James Securities Inc. (the “Placement Agent”), pursuant to which the Placement Agent acted as the sole placement agent for the Private Placement. In consideration for the foregoing, the Company has agreed to pay customary placement fees to the Placement Agent, including a cash fee equal to 3.5% of the gross proceeds raised in the Private Placement and issue warrants equal to 7.5% of the securities placed in the Offering. Pursuant to the Placement Agency Agreement, the Company has also agreed to reimburse certain expenses of the Placement Agent incurred in connection with the Private Placement.
