NUBURU closes public offering, raising gross proceeds of $38m
NUBURU Inc of Centennial, CO, USA (a dual-use defense & security integrated platform company) has closed its best-efforts public offering, generating gross proceeds of about $38m, before deducting placement agent fees and other offering expenses.
The offering consisted of 244,372,984 shares of common stock and/or pre-funded warrants to purchase shares of common stock, together with accompanying shares of Series B Preferred Stock. The combined public offering price was $0.1555 per share of common stock and accompanying Series B Preferred Stock, or $0.1554 per pre-funded warrant and accompanying Series B Preferred Stock, reflecting the $0.0001 exercise price of each pre-funded warrant. The $0.1555 combined public offering price represented premium of about 30% to the $0.1199 closing price of common stock on 15 July.
The offering was led by a New York-based single-family office, with participation from other well-known accredited investors and family offices.
Joseph Gunnar & Co LLC acted as the exclusive placement agent for the offering.
Because NUBURU’s stock traded below $0.10 during the trading day, it received notice indicating that it was in violation of Section 1003(f)(v) of the NYSE American Company Guide and that NYSE American would commence proceedings to delist the common stock. NUBURU intends to appeal this decision and implement a reverse stock split to regain compliance, for which it has already obtained stockholder approval.
“We are truly grateful for the support from our large investors today who closed our transaction. With their help and belief in our vision, we are now positioned to advance the proposed Tekne acquisition, substantially simplify our capital structure through the planned repayment of our outstanding debenture and continue building our integrated Defense & Security platform,” says executive chairman & co-CEO Alessandro Zamboni. “We will work quickly to implement a reverse stock split to regain compliance and build the stock value that our supportive investors deserve,” he adds.
“We look forward to continuing the Golden Power process, progressing toward the closing of the Tekne transaction and accelerating the integration of our software, photonics, electronic warfare, defense mobility and advanced manufacturing capabilities into a unified Defense & Security platform,” says Dario Barisoni, co-CEO of NUBURU and CEO of NUBURU Defense LLC.
