Nuburu stock jumped 11% in premarket Friday, ending a four-day slump, after its unit acquired a 10.7% stake in Italian software firm Orbit S.r.l. The $5 million deal is expected to be completed by 2026. Orbit projects strong revenue growth, while Nuburu’s defense JV with Maddox aims to generate $100 million annually by 2028 through advanced drone manufacturing.
