Tekne Acquisition Closed at 70%
Nuburu Defense bought 745,759 Tekne shares (67.1%) for €5.2M on October 15, 2026, taking its total stake to 70%; the three existing shareholders retain 30%.
-
€4M Deferred Plus €20M Earn-Out
Only €1.2M was paid at closing; €4.0M is due in four €1.0M installments through March 31, 2027. The earn-out is €20M cash with a €2M guaranteed annual minimum for FY2027-2036, and Nuburu is jointly and severally liable.
-
€29.7M Receivables Written Off
Nuburu waived €29,694,958.28 owed by Tekne — including the €27,693,000 shareholder loan — as a non-dilutive capital contribution, which is what bought down the earn-out from €29.7M to €20M.

NYSE American Delisting Warning
An October 19, 2026 letter found Nuburu violated Section 401(a) by not promptly disclosing the September 30, 2026 Esousa side letter and Brick Lane note cancellation. Citing prior violations, NYSE said any future violation will trigger immediate suspension and delisting proceedings.
Analysis · BURU · Manufacturing
Nuburu now controls 70% of Italy's Tekne S.p.A., paying €5.2M (€1.2M cash at closing, €4.0M deferred through March 2027) plus a €20M cash earn-out carrying a €2M annual guaranteed minimum through 2036 — a real, recurring cash obligation for a company with a ~$13M market cap. In exchange it wrote off €29.7M of Tekne receivables, including a €27.7M shareholder loan, as a capital contribution, cleaning up Tekne's balance sheet without diluting the minority holders. The bigger near-term risk is the NYSE American warning letter: regulators cited Nuburu's history of late disclosure and said any future violation will mean immediate suspension and delisting proceedings rather than another warning. That converts an already-thin listing into a probationary one.
