Nuburu, Inc. filings document material agreements, capital-structure actions, governance matters and shareholder approvals for a public defense and directed-energy technology company. Recent 8-K disclosures cover bond subscription and inventory-financing arrangements, international cooperation agreements for defense vehicle deployment, contractual joint venture terms for mobile additive manufacturing, and subsidiary activity involving Nuburu Defense.

Nuburu, Inc. filed a resale registration for up to 60,000,000 shares of Common Stock to permit YA II PN, LTD. (the Selling Stockholder) to resell shares issued under a Standby Equity Purchase Agreement (SEPA). The Company will not receive proceeds from resales by the Selling Stockholder; however, under the SEPA the Company may elect to sell shares to the Selling Stockholder and may receive up to $11.6 million based on the $0.20 closing price on April 20, 2026. The SEPA provides a $100 million Commitment Amount in the aggregate, is subject to an Exchange Cap and a 4.99% beneficial ownership limit for the Selling Stockholder, and requires that proceeds received under the SEPA be applied to repayment of a $25,000,000 Debenture until indefeasibly paid.
Nuburu, Inc. director and Co‑Chief Executive Officer Alessandro Zamboni reported two acquisitions of common stock. On December 31, 2025, Vanguard Holdings S.r.l., an entity owned by him, recorded an open‑market purchase of 4,332,525 shares at $0.3453 per share, held indirectly. A footnote explains this reflects the conversion of two Company convertible promissory notes of $545,000 and $900,000, plus interest, into 21,619,298 shares before adjustment for a 1‑for‑4.99 reverse stock split.
Separately, on October 1, 2025, Zamboni was granted 1,774,000 restricted stock units, which vested on October 31, 2025. After the 2026 reverse stock split, this grant is shown in the table as 355,511 shares of common stock held directly.
Nuburu, Inc. director Alessandro Zamboni filed an initial ownership report on Form 3. The filing establishes his status as a director of Nuburu but does not list any stock transactions, derivative positions, or current share holdings. It serves as a baseline disclosure of his insider status with the company.
Nuburu, Inc. reports a major strategic shift from industrial blue lasers to a dual-use defense, security, and critical‑infrastructure platform, while facing significant financial pressure. The company recorded a $79.1 million net loss in 2025 and an accumulated deficit of $200.5 million, and its auditors raised substantial doubt about its ability to continue as a going concern.
Management’s 2025 Transformation Plan centers on software‑orchestrated defense and resilience solutions, supported by acquisitions and investments including Lyocon (laser engineering), Orbit (operational resilience software), Tekne (defense vehicles and networks), SYME (inventory monetization fintech), Maddox (mobile additive manufacturing JV) and an H&K firearms stake. These deals are largely funded with convertible notes and receivables, increasing leverage and execution risk at a time when Nuburu has limited cash, a very small employee base, discontinued U.S. manufacturing, and must still regain NYSE American listing compliance and secure additional capital.
Nuburu, Inc. filed an amended report describing a bond investment with an affiliate of its executive chairman. On March 12, 2026, the company agreed to subscribe to initial bonds issued by Supply@ME Stock Company 3 S. (“SYME 3”) with a nominal value of EUR 5.25 million, maturing in March 2029.
The subscription price of EUR 5.25 million will be settled by offsetting EUR 4,824,294 of prior inventory advances Nuburu paid to SYME 3. The bonds fund inventory for Tekne S.p.A., are secured by Tekne inventory and related receivables, and accrue interest at three‑month Euribor plus 7.5% per annum, capped at 12%, with quarterly payments and various early redemption options.
Nuburu Inc: Amendment No. 1 to a Schedule 13G/A states that The Vanguard Group reports beneficial ownership of 0 shares of Common Stock as of 03/13/2026. The filing explains an internal realignment effective January 12, 2026 and cites SEC Release No. 34-39538 for disaggregated reporting by Vanguard subsidiaries. The form is signed by Ashley Grim on 03/26/2026.
Nuburu, Inc. entered into a letter of intent with the shareholders of Italian company Tekne S.p.A. to move toward acquiring a 70% equity stake. Nuburu first obtained a 2.9% interest and issued Tekne a January Convertible Receivable of EUR 13,000,000, later increased by EUR 3,692,000 to a total of EUR 16,692,000, which is intended to convert into a 32.1% interest.
After Italian Golden Power authorization and a planned EUR 13,000,000 capital increase for another 25% interest, Nuburu would buy an additional 10% from existing shareholders for EUR 6,000,000 in cash, reaching 70%. The parties also contemplate a restructuring of Tekne, potential purchase or lease of an industrial complex in Ortona, and development of new dual-use drone-related manufacturing lines, along with a spin-off of certain non-core assets.

Nuburu, Inc. entered into a Bond Subscription Agreement to subscribe for initial bonds of Supply@ME Stock Company 3 S. in a nominal amount of EUR 5.25 million, maturing in March 2029. The price will be settled mainly by offsetting EUR 4,824,294 of advance payments previously made under a prior USD 5.15 million convertible facility with Supply@ME Capital plc. The bonds pay interest at 3‑month Euribor plus 7.5% per year, capped at 12%, with quarterly payments starting July 8, 2026.

SYME 3 is an affiliate of SYME, whose founder and CEO, Alessandro Zamboni, also serves as Nuburu’s Executive Chairman and Co‑Chief Executive Officer.
