NUBURU completes public offering, raising $12m
NUBURU Inc of Centennial, CO, USA — which was founded in 2015 and developed and previously manufactured high-power industrial blue lasers — has completed its previously announced $12m public offering.
The public offering involved the issuance and sale of $12m in common stock and pre-funded warrants in lieu of shares (at a subscription price of $0.1428 per share, and $0.1427 per pre-funded warrant), representing 32,373,536 common shares and 51,660,075 pre-funded warrants. Additionally, the firm issued 126,050,417 common warrants to purchase up to 150% of the aggregate number of shares and pre-funded warrants (with an exercise price of $0.1714 per warrant share), which common warrants are immediately exercisable and expire five years from their date of issuance. The pre-funded warrants have an exercise price of $0.0001 per pre-funded warrant share, are immediately exercisable, and expire when exercised in full.
NUBURU received total gross proceeds of $12m, before placement agent fees and other expenses. Net proceeds are expected to fuel the firm’s phased acquisition plan and growth initiatives, positioning it to deliver solutions in defense and operational resilience. Key initiatives include:
- Delivery capital support to Tekne, underpinning the phased acquisition: NUBURU has recently secured a first-stage 3% equity interest, with the remaining 67% interest in Tekne anticipated in a second stage by the end of 2025. The capital support provided to Tekne, also by leveraging Supply@ME’s Inventory Monetization platform (in which NUBURU holds a strategic investment), is expected to be converted to equity ownership of Tekne, once the investment is approved by the Italian government and NUBURU can then exercise its option right to complete the second stage. Tekne has an existing portfolio valued at about $500m, comprising 152 orders. The target addressable market in the electronic warfare sector alone is projected to reach $19.4bn by 2028, indicating significant growth potential in this space.
- Fund the working & growth capital of Tekne US Joint Venture, unlocking $7.5m of Tekne’s existing APAC orders: The newly formed US-based joint venture (Tekne US JV), owned 80% by Nuburu Defense LLC and 20% by Tekne, is expected to drive innovation and growth in the Americas’ defense market. The joint venture will focus on developing advanced defense products tailored for the Americas, manufacturing and selling existing Tekne products in the region, and managing direct sales to non-Italian clients. The capital raised is expected to unlock $7.5m of Tekne’s existing orders, potentially generating up to 15% in net profit for the Tekne US JV. Additionally, the funds will support a supply chain financing strategy to strengthen the partnership between Tekne and Flyer Defense, a US company collaborating with Tekne to produce the Flyer 72-Heavy Duty (Flyer 72-HD) vehicle. This collaboration will focus on developing products that enhance mobility and defense capabilities for NATO allies.
- Strengthen defense & security market positioning by incorporating scalable Software as a Service (SaaS) businesses: In line with the vision to establish a defense & security hub announced on 21 February, NUBURU will pursue a controlling interest in Orbit S.r.l., a SaaS startup that specializes in operational resilience. Orbit already has an existing portfolio made of 18 clients and 2000 daily users. SaaS business models are highly scalable, with an anticipated EBITDA exceeding 40% and a projected target addressable market of $1.1bn in 2033. As NUBURU’s executive chairperson holds a controlling interest in Orbit, this transaction has been negotiated and approved by independent board members.
- Explore opportunistic blue laser partnerships: NUBURU’s team has been working to target potential M&A transactions in the blue laser sector to enhance synergies and solidify its leadership in defense technology innovation.
