 chief nuclear officer of operating power plants who guides our reactor engineering, operations and safety culture, experienced manufacturing and supply chain executives, and finance professionals (including a CFO with 30+ years of experience in investment management). This combination of nuclear industry knowledge and execution experience gives us confidence in our ability to achieve our goals.

| • |     | Strategic Fuel Supply Position: Our strategy centers on using LEU+ fuel (enriched to 5-10% U-235) to achieve long core life. Sourcing LEU+ fuel is integral to our strategy because it avoids the long lead time and approvals still required for high-assay low-enriched uranium (“HALEU”) (fuel enriched from 5-20%). As a member of the DOE HALEU Consortium, we are positioned to benefit from federal support in developing the HALEU supply chain, but we avoid the risk and uncertainty of using HALEU fuel directly. We are also exploring partnerships in fuel fabrication and potential fuel recycling to vertically integrate our fuel cycle over time. For further information on our fuel strategy, please refer to the section below entitled “Fuel Supply”. |

These key competitive strengths, including our cost-efficient modular product, our fast-track licensing plan, early engagement with potential customers, our seasoned team, and our secure fuel strategy, provide a solid foundation as we move toward commercial deployment of the Hadron Halo. Although other advanced reactor developers exist, we believe our focus on small (10 MWe) transportable MMRs and a strategy focused on engaging concurrently and early with regulators, suppliers, strategic partners, states, and customers will differentiate us in the market and enable us to achieve first mover advantage. Growth Strategy Our growth strategy is focused on scaling rapidly to meet growing electricity demand for clean energy while carefully managing key technology and regulatory milestones. The principal elements of our growth plan include:

| • |     | Licensing Milestones: Our goal is to submit our NRC 10 CFR Part 52 manufacturing license (ML) and combined license (COL) for the Hadron Halo by 2027–2028, enabling us to begin commercial deployment soon after with an anticipated review time of no longer than 18 months. We are targeting our first deployment (first-of-a-kind (“FOAK”)) unit by 2030, assuming timely regulatory approval. Meeting these licensing timelines is critical because regulatory clearance is a gating item for commercial deployment, and thus, revenue generation
