Terra Innovatum Global announced it has secured all key components for its SOLO reactor unit, marking a major execution milestone in the advanced reactor sector.

Terra Innovatum Global N.V. ("Terra Innovatum" or the "Company") (NASDAQ: NKLR), a developer of micro-modular nuclear reactors today announced that it has secured all key components of its SOLOTM reactor unit, representing a major execution milestone and a key point of differentiation within the advanced-reactor sector.

The Company has completed supply-chain alignment for both critical nuclear-grade and non-nuclear-grade components and systems, derisking manufacturing, construction timelines while ensuring future deployment readiness. All components have been aligned with vendors qualified to meet the strictest nuclear and industrial performance requirements.

"In advanced nuclear, supply-chain readiness is where serious programs separate themselves from concepts," said Alessandro Petruzzi, Co-Founder & Chief Executive Officer of Terra Innovatum. "By securing both nuclear-grade and non-nuclear components and systems at this stage, we are demonstrating that SOLO™ is engineered, industrialized and ready to be built."

KEY NUCLEAR GRADE COMPONENTS SECURED

Terra Innovatum has secured supply pathways for the following safety-critical, nuclear-grade components, which represent the highest barriers to entry in reactor construction:

Fuel

Control and Shutdown Mechanisms

Graphite

Pressure Vessel

Isolation Valves

Reactor Cooling Tubes

Core Support Structure

Instrumentation and Controls

Engineering, Procurement and Construction (EPC) Contractor

Early alignment across these elements reflects Terra Innovatum's emphasis on manufacturability, long-lead planning and regulatory-aware design from the outset of SOLO™'s construction and deployment.

NON-NUCLEAR GRADE COMPONENTS SECURED

In parallel, the Company has secured supply arrangements for non-nuclear-grade but mission-critical primary and secondary systems, ensuring full plant-level integration and execution continuity:

Helium Circulator

Turbine

Steam Generator

Primary and Secondary Piping

Condenser

Pumps

Instrumentation and Controls

Together, these systems underpin SOLO™'s power-conversion and thermal-management architecture and are essential to delivering reliable, dispatchable energy at commercial scale.

"Our progress across both the nuclear and non-nuclear supply chain reflects disciplined engineering and a design philosophy centered on execution and on exploiting consolidated R&D and past experience", said Marco Cherubini, Co-Founder, Chief Technology Officer & Product Director. "This momentum strengthens our path toward commercialization and reinforces Terra Innovatum's role in producing and delivering the next generation of scalable, reliable energy solutions."

NUCLEAR INDUSTRY STRUCTURAL ADVANTAGES

As global demand accelerates for clean, firm power (particularly for data centers, industrial facilities, and remote or energy-constrained regions), project sponsors, regulators, and capital providers are increasingly focused on execution risk rather than theoretical performance. Terra Innovatum's supply-chain readiness positions the Company ahead of much of the advanced-reactor field, where unresolved component sourcing remains a key development bottleneck.

This milestone supports continued progress across manufacturing planning, regulatory engagement and commercial discussions, as Terra Innovatum advances SOLO™ toward deployment.

ABOUT TERRA INNOVATUM & SOLO™

Terra Innovatum's mission is to make nuclear power accessible. We deliver simple and safe micro-reactor solutions that are scalable, affordable and deployable anywhere 1 MWe at a time.

Terra Innovatum is a pioneering force in the energy sector, dedicated to delivering innovative and sustainable power solutions. Terra Innovatum plans to leverage cutting-edge nuclear technology through the SOLO™ Micro-Modular Reactor (SMR™) to provide efficient, safe, and environmentally conscious energy. With a mission to address global energy shortages, Terra Innovatum combines extensive expertise in nuclear industry design, manufacturing, and installation licensing to offer disruptive energy solutions. Committed to propelling technological advancements, Terra Innovatum and SOLO™ are dedicated to fostering prosperity and sustainability for humankind.

It is anticipated that SOLO™ will be available globally by 2028. Conceptualized in 2018 and engineered over six years by experts in nuclear safety, licensing, innovation, and R&D, SOLO™ addresses pressing global energy demands with a market-ready solution. Built from readily available commercial off-the-shelf components, the proven licensing path for SOLO™ enables rapid deployment and minimizes supply chain risks, ensuring final cost predictability. Designed to adapt with evolving fuel options, SOLO™ supports both LEU+ and HALEU, offering a platform ready to transition to future fuel supplies.

SOLO™ will offer a wide range of versatile applications, providing CO2-free, behind-the-meter, and off-grid power solutions for data centers, mini-grids serving remote towns and villages, and large-scale industrial operations in hard-to-abate sectors like cement production, oil and gas, steel manufacturing, and mining. It also has the ability to supply heat for industrial applications and other specialized processes, including water treatment, desalination and co-generation. Thanks to its modular design, SOLO™ can easily scale to deliver up to 1GW or more of CO2-free power with a minimal footprint, making it an ideal solution for rapidly replacing fossil fuel-based thermal plants. Beyond electricity and heat generation, SOLO™ can also contribute to critical applications in the medical sector by producing radioisotopes essential for oncology research and cancer treatment.
