Terra Innovatum To Go Public Through Business Combination with GSR III Acquisition Corp

NEW YORK, NY and AUSTIN, TX, April 22, 2025 (Newswire.com) - Terra Innovatum Srl ("Terra Innovatum," or the "Company"), a developer of micro-modular nuclear reactors, and GSR III Acquisition Corp. ("GSRT") (NASDAQ:GSRT), a publicly traded special purpose acquisition company ("SPAC"), today announced that they have entered into a definitive Business Combination Agreement dated April 21, 2025 (the "BCA"), which will position Terra Innovatum to become a publicly listed company on the Nasdaq under the ticker symbol "NKLR." The transaction is expected to close in the second half of 2025.

ANNOUNCEMENT HIGHLIGHTS

• Micro-Modular Reactor for Scalable, Off-Grid Deployment: Terra Innovatum designs and will develop advanced micro-modular reactors for flexible, off-grid deployment-addressing the rapidly growing global demand for low-carbon, cost-efficient, and reliable electricity and heat generation.

• Capitalizing on Global Energy Megatrends: Terra Innovatum's SOLO™ micro-modular reactor will be engineered to meet the rapidly evolving electricity and heat needs of diverse high-demand sectors-including industrial manufacturing, mining, rural and remote communities, defense installations, desalination, healthcare (including isotope production), and AI/data centers.

• Predictable Electricity and Heat Costs for Up to 45 Years: With estimated ultra-long refueling intervals of 15-45 years, depending on configuration, and an exceptionally low $0.07/kWh anticipated levelized cost of electricity, SOLO™ will offer a transformative energy solution for the future.

• Assembled with Proven, Standard Components and Fuel: SOLO™ reactors will be factory-assembled using proven, existing, standard off-the-shelf components and approved, widely available LEU 4.95% fuel-minimizing supply chain risks and accelerating deployment. The use of standard parts will enable a de-risked business model, while embedded safeguards and redundant systems ensure an inherently safe and resilient design.

• Founded and Led by Nuclear Industry Veterans: Terra Innovatum's leadership team brings together over 180 years of collective expertise across nuclear engineering, reactor design, safety, operations, and regulatory affairs-anchoring the company in deep technical knowledge and proven execution in the nuclear sector.

• Regulatory Engagement Plan (REP) and Anticipated Commercialization: Terra Innovatum submitted its regulatory engagement plan to the NRC in January 2025, marking a critical milestone on its path to anticipated commercial deployment in 2028.

• Public Investor-Aligned Transaction Terms and Structure: The transaction values Terra Innovatum at a pre-money equity valuation of $475 million, offering an attractive entry point relative to publicly traded nuclear reactor developers.

• Financing: The development and commercialization efforts will be supported by up to approximately $230 million in gross proceeds before accounting for redemptions and any committed financing.

Alessandro Petruzzi, Co-Founder & CEO of Terra Innovatum, said: "We are excited to take Terra Innovatum public, which will mark a major milestone in our mission to make nuclear power simple, safe, and scalable. Our reactor, SOLO™, aims to bring low cost, off-grid, zero-carbon power to industrial, remote, and high-demand sectors. With 1 MWe at a time for a single SOLO unit, we can leverage our modularity to power up to one GWe with a lower footprint of a similar GWe plant. Backed by strong leadership and GSRT's support, we're ready to accelerate deployment and reshape the future of clean energy."

Gus Garcia, Co-CEO of GSRT commented: "This is a game-changing partnership. Terra Innovatum gives our shareholders access to a company at the forefront of nuclear innovation. With proven leadership and a next-gen micro-reactor design, Terra Innovatum is built for the future-delivering safe, cost-efficient energy at global scale. We believe this is the right team, the right technology, and the right time."

Lewis Silberman, Co-CEO of GSRT continued: "The nuclear renaissance is real-and we believe Terra Innovatum's SOLO™ reactor will lead it. With a massive addressable market and a fast track to commercialization, Terra Innovatum stood out from day one. When it enters the public markets, we believe Terra Innovatum is poised to become one of the most exciting clean energy success stories of the decade."

TERRA INNOVATUM'S MICRO-MODULAR NUCLEAR BREAKTHROUGH: SOLO™

SOLO™ is a compact, cube-shaped micro-reactor designed to deliver 1 MWe of clean, reliable power. With the reactor design finalized in October 2024, Terra Innovatum began formal engagement with the NRC in January 2025. Each unit uses standard LEU fuel and helium gas cooling-eliminating meltdown risk, explosion potential, and proliferation concerns. Housed in a 2.5-meter-thick concrete Monolith, SOLO™ requires no Emergency Planning Zone (EPZ) and radiation exposure to the public is well below legal safety limits.

• Commercialization-Ready and Scalable by Design: Engineered over six years by a seasoned team, SOLO™ is designed for mass deployment using off-the-shelf components. Its proven licensing path, low-cost structure, and compatibility with both LEU and future High-Assay Low-Enriched Uranium ("HALEU") fuels position it for global rollout in 2028.

• Built for Versatility, Designed for Impact: From powering off-grid communities and data centers to decarbonizing heavy industry, SOLO™ will adapt to diverse energy needs. It will also support high-grade heat applications like desalination and isotope production for cancer treatment-delivering zero-carbon energy at scale.

• Built on Experience, Engineered for Safety: Backed by 180+ years of nuclear expertise, SOLO™ was designed with safety as a non-negotiable. The reactor core has been designed to enable safe decommissioning as it fits in existing licensed commercially available casks. Even 10 years of continuous exposure results in less radiation than a single chest X-ray. With a core built for safe decommissioning and passive safety features built in, SOLO™ will set the standards for micro modular nuclear technology.

Dr. Cesare Frepoli - Co-Founder, Chief Operating Officer & Director of Licensing and Regulatory Affairs: "Our approach to licensing is rooted in decades of industry expertise and a deep respect for safety and compliance. We've engineered SOLO™ from day one to align with rigorous regulatory frameworks while introducing innovation that simplifies approval pathways. We're not just building a reactor-we're building trust with regulators and the public."

Dr. Marco Cherubini - Co-Founder, Chief Technology Officer & Product Director: "SOLO™ is the result of relentless engineering, innovation, and precision. Every component-from its core physics to its modular architecture-has been designed to deliver unmatched safety, efficiency, and scalability. We're not adapting yesterday's technology; we're redefining what nuclear can be for the 21st century."

Dr. Massimo Morichi - Partner, Chief Strategy Officer & Safeguards Director: "Our strategic focus is grounded in building a nuclear solution that meets the world's growing energy needs without compromising on non-proliferation and international safeguards. SOLO™ has been designed not only to power industries and communities, but to set a new global benchmark for secure and responsible deployment."

Mr. Guillaume Moyen - Partner, Chief Financial Officer: "We've engineered financial transparency and discipline into the core of Terra Innovatum's business model. From predictable CAPEX to low OPEX, SOLO™ offers a compelling value proposition that de-risks infrastructure investment in next-gen nuclear for our investors and our customers."

Mr. Giordano Morichi - Partner, Chief Business Development Officer & Investor Relations: "With trillions in capital seeking clean, scalable solutions, nuclear energy is finally receiving the recognition it deserves. Our decision to go public reflects the maturity of our technology, enabling a rapid go-to-market response to the growing demand for low-carbon energy. SOLO™ is a category-defining platform designed for global scalability and impact. This transaction marks the beginning of Terra Innovatum's global deployment journey, offering the world a unique opportunity to invest in the future of nuclear energy."

PUBLIC LISTING & TRANSACTION OVERVIEW

The proposed business combination is expected to generate up to approximately $230 million in gross proceeds before accounting for redemptions and any committed financing.
