NUBURU prices $12m public offering
NUBURU Inc of Centennial, CO, USA — which was founded in 2015 and developed and previously manufactured high-power industrial blue lasers — has announced the pricing of a $12m public offering, raising capital to advance its transformation strategy. The firm says that the offering marks a pivotal step in strengthening its position as an emerging leader in the defense and security technology sector.
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 prefunded warrant), representing 32,373,536 common shares and 51,660,075 pre-funded warrants. Additionally, the firm issued common warrants to purchase up to 150% of the aggregate number of common shares (or pre-funded warrants in lieu of common shares), or 126,050,417 shares, 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 prefunded warrants have an exercise price of $0.0001 per prefunded warrant share, are immediately exercisable, and expire when exercised in full. The subscription of the offering was led with a $10m investment by Esousa Group Holdings LLC, a New York-based family office, that also included participation from other well-known institutional and accredited investors.
Joseph Gunnar & Co LLC is serving as the exclusive placement agent in connection with the offering.
Strategic use of proceeds
NUBURU anticipates 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’ 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.
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 and 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 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 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.
“This transformative capital raise empowers NUBURU to execute our strategic vision with precision and confidence,” says executive chairman Alessandro Zamboni. “By securing the path for the controlling interests in Tekne and Orbit, and launching the Tekne US JV, we are building a robust defense & security hub that drives innovation, strengthens global partnerships, and delivers unparalleled value to our stakeholders.”
