NUBURU Announces Proposed Premium-Priced Public Offering Expected to Provide Sufficient Funding to Consummate the Acquisition of a Controlling Interest in Tekne and Extinguish Outstanding Indebtedness and Related Stock-Based Amortizations

Offering expected to be priced above the current market price of the Company’s common stock, with proceeds intended to satisfy Golden Power requirements for the announced proposed Tekne acquisition, extinguish $16.75 million in principal amount of outstanding indebtedness in full - ending related equity-line share issuances - and halt equity-line use for at least 90 days.

NUBURU, Inc. (NYSE:BURU), a next-generation dual-use Defense & Security integrated platform company, today announced the commencement of a proposed best-efforts public offering of up to $38.0 million of securities of the Company, as described in the preliminary prospectus included in the Company’s registration statement on Form S-1 filed with the U.S. Securities and Exchange Commission (the "SEC").

Under the proposed terms, the offering is expected to be priced above the current market price of the Company’s common stock, with a proposed public offering price of $0.1555 per share (or equivalent security), representing a 5% premium to the closing price of the Company’s common stock on July 10, 2026. The offering is subject to market and other conditions, including final pricing negotiations, and there can be no assurance as to whether or when the offering may be completed, the actual size of the offering, or the final terms of the offering.

If completed and fully subscribed, the Company intends to use the net proceeds to deliver significant key strategic and balance-sheet advantages directly aligned with NUBURU's Defense & Security transformation plan:

• satisfy the financial assurances requirements associated with the Italian Government Golden Power review and position NUBURU to complete its previously announced proposed acquisition of a 70% controlling interest in Tekne S.p.A. ("Tekne"), subject to Golden Power clearance and other closing conditions;
• redeem in full principal outstanding indebtedness of approximately $15.5 million (the "Debenture") and $1.25 million of convertible notes issued in connection with the previously announced Lyocon acquisition;
• end the cycle of satisfying monthly installments under the Debenture through recurring stock issuances at prevailing market prices under the Company’s standby equity purchase agreement;
• add primary equity capital and materially strengthen the Company’s stockholders’ equity and pro forma tangible book value in support of its NYSE American continued-listing compliance efforts; and
• support near-term acquisition, working-capital and platform-execution requirements, enabling NUBURU to halt use of its equity line for at least 90 days, subject to completion of the offering and receipt of sufficient net proceeds.
