Terra Innovatum Srl, a company developing micro-modular nuclear reactors, announced it has secured $37.5 million in financing as it moves closer to merging with GSR III Acquisition Corp. (NASDAQ:GSRT).
The funding package consists of roughly $32 million from a private investment in public equity (PIPE) led by Segra Capital Management, alongside about $5.5 million from a bridge facility that will convert into common shares once the deal closes.
The capital will advance licensing and construction of Terra Innovatum’s SOLO™ micro-modular reactor, a system designed to generate 1 MWe of power.
“The PIPE proceeds will strengthen our balance sheet at close and help us execute on the licensing and commercialization of our first-of-a-kind SOLO™ micro-modular reactor,” said Alessandro Petruzzi, CEO of Terra Innovatum, in Thursday’s release.
GSR III has called a shareholder meeting for October 7, 2025, to vote on the proposed merger. Investors on record as of September 15, 2025, will be entitled to cast their ballots. If approved, the combined company will adopt the Terra Innovatum name and begin trading on Nasdaq under the ticker NKLR.
The SOLO™ platform is being marketed as a flexible energy solution for sectors such as data centers, industrial operations, and remote community power grids, with the ability to scale output up to 1 GW.
The Benchmark Company acted as lead placement agent for the financing round.
