Item 1.01 Entry into a Material Definitive Agreement

Heckler & Koch AG Investment

As part of ongoing efforts of Nuburu, Inc. (the “Company,” “we,” “us,” or “our”) to invest in assets to build out its Defense & Security Platform, on February 6, 2026, we entered into a Securities Purchase Agreement (the “H&K Acquisition Agreement”) with Brick Lane Capital Management Limited (“Brick Lane”) pursuant to which we acquired from Brick Lane 295,000 shares (or approximately 0.8% of the outstanding common shares) of Heckler & Koch AG (“H&K”), a leading manufacturer of small firearms for NATO and EU countries whose shares are listed on Euronext Paris under the ticker MLHK, for an aggregate purchase price of $15,000,000, which was paid by Subordinated Convertible Note (the “H&K Acquisition Note”). The H&K Acquisition Note bears no interest except in the event of a default, has a March 19, 2027 maturity date, and is convertible for $0.1515 per share, which was the closing volume-weighted average price on the day prior to the execution date of the H&K Acquisition Agreement. Conversion of the note is limited in the event stockholder approval or an increase in authorized shares is required, or when conversion would result in Brick Lane and its affiliates beneficially owning more than 9.9% of our then outstanding shares of Common Stock. The H&K Acquisition Note is subordinate to (i) the currently outstanding Series A Preferred Stock, solely with respect to dividend rights and rights on the distribution of assets on any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, and (ii) the outstanding debenture issued to YA II PN, LTD in December of 2025. We are also required to file a registration statement for the resale of shares of common stock issuable upon conversion of the H&K Acquisition Note, which we anticipate will occur in April.

Transfer of Outstanding Preferred Stock

As part of our ongoing efforts to eliminate liabilities and return to compliance with NYSE stockholder equity requirements, on February 6, 2026, we entered into an exchange agreement with Indigo Capital LP (“Indigo”), pursuant to which we agreed to issue a pre-funded warrant (the “Indigo Warrant”) in exchange for the transfer of 844,938 shares of our Series A Preferred Stock held by Indigo into our treasury (the “Exchange Agreement”). The number of shares of Common Stock issuable under the Indigo Warrant (55,771,485) for a nominal exercise price of $0.0001 per share was determined using the closing volume-weighted average price on the day prior to the execution date of the Exchange Agreement. In accordance with the terms of the Indigo Warrant, we may not issue or sell any shares of common stock to Indigo under the Indigo Warrant which would result in Indigo and its affiliates beneficially owning more than 4.99% of the then outstanding shares of common stock. The Indigo Warrant is exercisable immediately for three years until February 6, 2029.

Orbit Amendment

As previously disclosed, on October 31, 2025, we, our subsidiary Nuburu Defense, LLC, Alessandro Zamboni, and Vanguard Holdings S.r.l. (“Vanguard”), a newly-formed Italian limited liability company wholly owned by Alessandro Zamboni, entered into a Sale, Purchase and Investment Agreement (the “Orbit Agreement”) for the sale of all of the ownership interests in Orbit S.r.l. (“Orbit”) to Nuburu Defense (the “Orbit Acquisition”). Nuburu Defense will acquire all outstanding capital stock of Orbit from Vanguard for an aggregate purchase price of $12.5 million, consisting of $3.75 million in cash (which has already been paid) and $8.75 million in securities (the “Orbit Consideration”).

Subject to obtaining stockholder approval as required by NYSE American rules and the terms of the Orbit Agreement, we agreed to pay the non-cash portion of the Orbit Consideration in the amount of $8.75 million, by December 31, 2026, in the form of convertible preferred shares. On February 9, 2026, the parties to the Orbit Agreement entered into an amendment to issue 50,000,000 shares of Common Stock in lieu of the obligation to issue preferred shares (the “Amendment”).

Since Orbit is wholly owned by Alessandro Zamboni, our Executive Chairman and Co-Chief Executive Officer, indirectly through Vanguard, the Orbit Acquisition constitutes a related party transaction under U.S. securities laws and, as a result, the Orbit Acquisition, Orbit Agreement, and Amendment have been reviewed and approved by our independent directors and our Audit Committee.
