(the “Company”) and its subsidiary, Nuburu Defense, LLC (“Nuburu Defense”), entered into an Investment Agreement (the “Agreement”) with Tekne S.p.A. (“Tekne”) and Ambrogio D’Arrezzo, Carlo Ulacco, and Andrea Lodi, the shareholders of Tekne (collectively, the “Shareholders”) pursuant to which the Company agreed to contribute additional financial resources to Tekne and purchase shares of Tekne from the Shareholders in exchange for obtaining a 70% equity interest in Tekne. Pursuant to a Share Transfer and Shareholder Convertible Loan Agreement (the “Tekne Purchase Agreement”), effective as of January 13, 2026, between the Company and the Shareholders, the Company obtained a 2.9% interest in Tekne from Mr. D’Arrezzo and the Company issued to Tekne €13,000,000 of financial support (the “Tekne Convertible Receivable”). Under the Tekne Purchase Agreement, Mr. D’Arrezzo agreed to sell a 2.9% interest in Tekne to the Company or its subsidiary, in exchange for the issuance of a subordinated convertible note by the Company to Mr. D’Arrezzo. Pursuant to a letter dated March 19, 2026, among the Company, Nuburu Defense and the Shareholders, the Company contributed an additional €3,692,000 to Tekne, which increased the amount of the Tekne Convertible Receivable from €13,000,000 to €16,692,000. Under the Agreement, the Company agreed to contribute (i) an additional €1,000,000 to Tekne by May 28, 2026, which increased the amount of the Tekne Convertible Receivable to €17,692,000, and (ii) up to $12,000,000 in additional funding from time to time as agreed to by the parties, which will increase the amount of the Tekne Convertible Receivable. Subject to receiving approval from the Italian government under the Golden Power Regulations, a declaration that the proposed transaction does not fall within the scope of the Golden Power Regulations, or the expiration of the applicable statutory time limit without action by the Italian government (any of which constitutes a “GP Authorization”) by September 30, 2026 (the “Approval Deadline”), Nuburu Defense (or a different subsidiary designated by the Company) will receive a 57.1% interest in Tekne in exchange for payment of a subscription price of €29,692,000 (which consists of the amounts contributed under the Tekne Convertible Receivable to date and a cash payment of up to €12,000,000 for the remainder) (the “Subscription Price”). The closing of the transaction is scheduled to occur within 30 calendar days of the receipt of the GP Authorization (the “Closing Date”). Following its payment of the Subscription Price, on the Closing Date, Nuburu Defense will purchase 10% of Tekne’s share capital held by the Shareholders on a pro rata basis per Shareholder (the “Stock Purchase”) for total consideration of (i) €5,200,000 in cash paid on the Closing Date and (ii) an earn-out amount consisting of 5% of the annual revenues generated by Tekne from 2027 up to and including 2036, up to a maximum total amount of €29,692,000 (the “Earn-Out”). Following the Stock Purchase, Nuburu Defense will own a 70% interest in Tekne. The Earn-Out owed to each Shareholder on a pro rata basis will be determined based on the financial statements of Tekne prepared by the Company under U.S. generally accepted accounting principles. The Earn-Out per year is payable annually by June 30 of the following year in cash or in shares of the Company’s common stock (the “Common Stock”), at the option of the Company. If the Earn-Out is to be paid in shares of Common Stock, the number of shares will be determined based on the volume weighted average price of the Common Stock on the last 20 trading days prior to the date of filing of the Company’s Annual Report on Form 10-K with the Securities and Exchange Commission. If Nuburu Defense transfers a controlling stake in Tekne, subject to certain exceptions, Nuburu Defense will be required to, at its option, pay the outstanding balance in respect of the maximum amount of €29,692,000 to the Shareholders or provide that the transferee of such controlling interest in Tekne will assume the payment obligation. Under the Agreement, if the Italian government provides an authorization under the Golden Power Regulations that contains requirements or recommendations imposed on Tekne or the other parties to the transaction, the GP Authorization will be deemed to be fulfilled unless a party (other than Tekne) provides written evidence to the other parties within 5 business days that proceeding with the transaction will have a significantly detrimental effect on Tekne’s prospective valuation or that the requirements entail an additional financial commitment for the parties that is considered excessive in relation to the provisions of the Agreement (a “Justified Reason”). If the Shareholders or Nuburu Defense provide notice of a Justified Reason, the parties must follow a procedure to resolve such issue through negotiations as provided in the Agreement. If no agreement is reached within the specified time period, the condition precedent of obtaining GP Authorization will be deemed to not be fulfilled. If the GP Authorization is not received by the Approval Deadline, the Agreement will be deemed automatically terminated and Tekne will be required to repay the Tekne Convertible Receivable within 30 business days of receiving the request from Nuburu Defense; provided that, in certain circumstances, the Tekne Convertible Receivable will be permitted to be repaid in 60 equal monthly installments of principal. Under the Agreement, from the signing of the Agreement until the Closing Date (the “Interim Period”), Tekne may not undertake actions outside of ordinary business operations without receiving the prior written consent of Nuburu Defense. During the Interim Period, the parties agree to prepare and file any required documents necessary to obtain the GP Authorization and to
