Item 1.01 Entry into a Material Definitive Agreement

Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing

Item 3.02 Unregistered Sales of Equity Securities

On April 29, 2025, Nuburu, Inc. (the “Company”) received a notice of noncompliance with NYSE American continued listing standards (the “2025 Notice”) indicating that the Company was not in compliance with Section 1003(a)(i) of the NYSE American LLC Company Guide (the “Company Guide”), which requires a company to maintain stockholders’ equity of $2.0 million or more if it has reported losses from continuing operations or net losses in two of its three most recent fiscal years. On July 22, 2025, NYSE American notified the Company that it had accepted the Company’s plan outlining definitive actions that the Company has taken or will take to regain compliance with NYSE American’s continued listing standards (the “Compliance Plan”) and granted a plan period through October 29, 2026.

On May 12, 2026, in light of its reported stockholders’ deficit of approximately $15.2 million as of December 31, 2025 and historical net losses, the Company received a notice of noncompliance with NYSE American continued listing standards (the “2026 Notice”) indicating that the Company was not in compliance with Section 1003(a)(ii) of the Company Guide, which requires a company to maintain stockholders’ equity of $4.0 million or more if it has reported losses from continuing operations or net losses in three of its four most recent fiscal years. In connection with the 2026 Notice, the NYSE American is not requiring that a new compliance plan be provided by the Company and the Company will continue to operate in accordance with the Compliance Plan previously accepted by NYSE American.

As part of its ongoing efforts to eliminate liabilities and return to compliance with NYSE stockholders’ equity requirements, on May 11, 2026, the Company entered into an exchange agreement (the “Exchange Agreement”) with Indigo Capital LP (“Indigo”), pursuant to which, at Indigo’s option, within 10 business days of the receipt of a notice to exchange from Indigo, the Company will issue pre-funded warrants (the “Indigo Warrants”) in exchange for the transfer to the Company in multiple closings of up to 446,946 shares of its Series A Preferred Stock held by Indigo. On May 11, 2026, in exchange for 71,430 shares of Series A Preferred Stock, the Company issued an Indigo Warrant (the “Initial Indigo Warrant”) that is exercisable for up to 4,398,399 shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”) for a nominal exercise price of $0.0001 per share. The number of shares issuable under an Indigo Warrant is determined using the lowest volume-weighted average price for the Common Stock during the five business days prior to the closing date of such transaction discounted by 30%. In accordance with the terms of the Indigo Warrants, we may not issue or sell any shares of Common Stock to Indigo under the Indigo Warrants which would result in Indigo and its affiliates beneficially owning more than 4.99% of the then outstanding shares of Common Stock. The Initial Indigo Warrant is exercisable immediately for three years until May 11, 2029.
