NEW YORK, NY / GLOBE NEWSWIRE / November 17, 2025 / – Terra Innovatum Global N.V. ("Terra Innovatum" or the “Company”) (NASDAQ: NKLR), a developer of micro-modular nuclear reactors, today reported its third quarter fiscal year 2025 financial and operating results.

Alessandro Petruzzi, Co-Founder & CEO of Terra Innovatum, said, “Terra Innovatum and the broader nuclear industry are undergoing a critical inflection point where massive clean energy demand and regulatory and geopolitical tailwinds are converging. As the first public microreactor developer to use non-proliferant commercially available LEU and off-the-shelf components, we have an incredible opportunity to capture this moment and become a major player in the new era of nuclear energy production by delivering safe, reliable and low-cost power to the world.”

“We have a clear path to deploy our micro-modular solution by 2027 and commercialize by 2028. Our design is complete, our licensing process with the U.S. NRC is well defined, the supply chain is fully in place and we have the funds to get us to FOAK deployment. Our primary focus in the next 12 months is to 1) progress the U.S. NRC process with submittal of the Safety Analysis Report by mid-2026 and Operating License activities expected to commence in early 2026, 2) start the manufacturing activities at third-party supplier factories and 3) build a book of committed orders for our SOLOTM solution. We are confident in our ability to execute on these priorities and are excited for the future.”
