Terra Innovatum Secures Water-Independent Cooling Solution for SOLO™ Reactor Through Supply Agreement with SPG Dry Cooling Advances water-independent heat rejection capability and strengthens scalable balance-of-plant supply chain Supports global deployment across water-constrained and remote environments Water-independent cooling represents a key enabler of global deployment, addressing a primary siting constraint for energy infrastructure and expanding the addressable market for the SOLO™ platform. NEW YORK, May 18, 2026 (GLOBE NEWSWIRE) -- Terra Innovatum Global N.V. (NASDAQ: NKLR) (“Terra” or the “Company”), developer of the SOLO™ Micro-Modular Reactor, today announced that its wholly owned affiliate, Terra Innovatum S.r.L. has signed an agreement with SPG Dry Cooling for the supply of an Air-Cooled Condenser (ACC) to support the first-of-a-kind (FOAK) deployment of the SOLO™ microreactor. The Air-Cooled Condenser is a critical component of the power conversion system, enabling efficient heat rejection without reliance on water-based cooling. This capability significantly expands deployment flexibility across water-constrained and remote environments, while supporting the scalability of the SOLO™ platform. This agreement paves the way for potential future collaboration for the Supply of SPG Dry Cooling`s standardized BoxAir solution to enable efficient fleet scale deployment. “This agreement reflects the realities of deploying advanced energy systems at scale,” said Alessandro Petruzzi, Co-Founder, and Chief Executive Officer of Terra Innovatum. “By eliminating dependence on water-based cooling, the SOLO™ platform can be deployed across a significantly broader set of environments, unlocking global demand. At the same time, we are aligning with proven industrial partners to build a supply chain designed for standardization, and repeatable deployment.” Torsten Andersch, Executive Vice-President of SPG Dry Cooling, added, “As a global leader in air-cooled condenser systems, we leverage decades of expertise in delivering water-free heat rejection solutions across the most demanding environments. We are proud to support Terra Innovatum in the FOAK deployment of the SOLO™
