"We are thrilled to partner with Paragon, a leading nuclear component manufacturer who has the nuclear engineering know-how, capabilities, and capacity to support the global manufacturing and deployment of our SOLO™ units once commercialized. We are working closely with their world-class team to implement NRC-approved I&C systems into our advanced nuclear reactors to ensure SOLO™ maintains industry-leading performance, safety and reliability," announced Alessandro Petruzzi, Co-founder & CEO of Terra Innovatum. "This partnership reflects the agility of our model as we aim to leverage the existing nuclear supply chain and licensed components for our reactor design and production, which accelerates our regulatory and commercial pathway."

Tighe Smith, Chief Nuclear Officer of Paragon commented: "We're proud to collaborate with Terra Innovatum and help push the frontier of advanced nuclear forward to address worldwide energy demand. We are well positioned to support their innovative and unique design elements as well as deployment plans as an established partner-of-choice for the advanced reactor industry. We share in Terra Innovatum's long-term commitment to both innovation and safety profile and are excited to build the future of nuclear together."

Giordano Morichi, Partner, Chief Business Development Officer & Investor Relations of Terra Innovatum continued: "We engineered SOLO™ for modular scalability and rapid commercialization, and this partnership with Paragon marks a critical first step toward our 2028 deployment timeline. By aligning with established industry leaders like Paragon, we are not only integrating proven I&C and safety systems into our technology-we are also laying the foundation for a resilient, responsive supply chain across the U.S. and globally. Together, we're accelerating our mission to deliver low-cost, zero-carbon, and highly reliable energy to the places that need it most."

"We deeply recognize the urgency of bringing advanced nuclear technologies like SOLO™ to market. Our expertise in delivering high-integrity safety systems aligns perfectly with Terra Innovatum's ambitious roadmap. We are committed to supporting their deployment goals by ensuring that all instrumentation and control components are engineered, tested, and delivered with the highest standards of nuclear-grade reliability," concluded John Portillo, Vice President of Paragon.

The MOU formalizes a strategic collaboration to initiate the design integration and validation of advanced I&C systems for Terra Innovatum's SOLO™ reactor, as well as related manufacturing support for global deployment. Work has already begun between the engineering teams, and initial planning milestones are underway. The agreement lays the foundation for purchase orders, long-term service contracts, and commercial engagements, signaling a strong mutual commitment to accelerate deployment and scale.

**Recent Highlights**

Terra Innovatum recently announced a proposed business combination with GSR III Acquisition Corp., positioning the Company to accelerate its mission of delivering zero-carbon, cost-efficient, and reliable power. SOLO™ is the first micro-modular reactor designed to operate on widely available Low-Enriched Uranium (LEU) and is built using commercial off-the-shelf components, streamlining regulatory review and shortening construction timelines. In May, the Company submitted an advanced nuclear proposal to the New York State Energy Research and Development Authority's Advanced Nuclear Request for Information, outlining plans for a potential reactor site, production facility, and deployment opportunities to address New York's 2040 zero-carbon goal. Earlier this year, Terra Innovatum submitted its regulatory engagement plan to the U.S. Nuclear Regulatory Commission (NRC), a critical step toward its targeted first commercial deployment in 2028.
