Terra Innovatum Srl, the developer of micro-modular nuclear reactors, and GSR III Acquisition Corp. (NASDAQ:GSRT), a publicly traded special purpose acquisition company, announced Friday that they have secured an additional $5 million in private investment in public equity (PIPE), bringing total committed equity financing for their planned business combination to $42.5 million. This figure includes approximately $37 million from PIPE investors and $5.5 million from a funded bridge facility.
“Terra Innovatum is bringing a differentiated nuclear solution that can deliver low-cost, zero-carbon and reliable energy to the world; a much-needed innovation as the demand for clean energy continues to rapidly increase,” said Alessandro Petruzzi, CEO of Terra Innovatum. “We have developed a simple path to market, which circumvents the need for government subsidies or extensive research, by designing a reactor that is small, runs on widely available components and fuel, and has a clear licensing plan. We are encouraged by the recent investor support as the investment community continues to appreciate our value proposition.”
Giordano Morichi, Partner, Chief Business Development Officer & Investor Relations at Terra Innovatum, added, “The $42.5 million in equity financing, along with net proceeds from the trust account after redemptions, will accelerate the deployment of our FOAK reactor and strengthen our position ahead of full-scale production. Backed by a diverse group of investors who share our vision, we are fast-tracking the commercialization of the SOLO™ micro-modular reactor and remain firmly on track for market deployment by 2028.”
