Key Transactional and Operational Developments

The recent movements at Nuburu occur alongside several operational shifts within its defense and security segments. As of March 31, 2026, the company disclosed billings of approximately $660,000 and executed orders totaling $500,000 in these sectors. A specific highlight includes the directed-energy division, which reported $280,000 in billings and secured a $250,000 deployment order for a portable laser dazzler system. This order was placed by a government-owned defense electronics organization located in the Asia-Pacific region.

Furthermore, Nuburu is advancing its joint venture with Maddox Defense Incorporated. This partnership has entered the production phase for the Mobile Additive Manufacturing Container platform, aimed at producing components for drones and defense applications. This initiative is backed by structured funding and initial capital, with a target deployment window of 6 to 9 months. Phase I of this manufacturing joint venture is currently active, with integration and manufacturing tasks being performed at the Maddox Defense facility in Houston.

As of December 31, 2025, cash reserves were reported at approximately $24.7 million, a significant increase from the $0.2 million held during the previous year. Total assets reached roughly $49.8 million during this period, and the stockholders' deficit saw a significant narrowing.
