 emphasizing simulation to reduce expensive late-stage design changes, will allow us to innovate efficiently. Protecting our intellectual property arising from R&D is also a priority, as further discussed below under the section entitled “ Intellectual Property.” Government Regulations Nuclear energy is a heavily regulated industry, and our business is subject to extensive government oversight at multiple levels. Key regulatory and legal considerations include:

| • |     | NRC Licensing: Commercial deployment of our reactors in the U.S. and U.S. Territories require licensing by the NRC under 10 CFR Part 52, the framework for new reactor design certifications and combined construction/operating licenses. These licensing regulations cover reactor design and construction, with a core goal of ensuring adequate protection for the public and the environment. Historically, NRC approvals for new reactor designs have taken 8-10 years. However, recent initiatives and legislative support such as Executive Orders, the Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy Act of 2024 (ADVANCE Act), and more aim to streamline licensing processes for MMRs. We are planning for approximately a 3-4 year review timeline for the Hadron Halo ML, leveraging new NRC guidance tailored to microreactors. Accelerated licensing initiatives apply specifically to MMRs with each licensing action taking no longer than 18 months. Licensing larger SMR designs and traditional large-scale reactors involves substantially longer overall review periods compared to the accelerated licensing track anticipated for MMRs. We maintain consistent and active dialogue with the NRC to ensure our licensing approach meets all regulatory requirements. Hadron Energy began early engagements with the NRC in July 2024, with formal engagement starting in April 2025 through the submission of our letter of intent. In addition, Hadron Energy’s Regulatory Engagement Plan (REP) was submitted to the NRC on May 9, 2025. |

| • |     | Operational Regulation: Once deployed, our reactors will be subject to ongoing NRC operational oversight and inspection, similar to other nuclear facilities. This includes adherence to regulations governing reactor operations, operator training and certification, physical security, and emergency preparedness. For MMRs, we anticipate that the NRC may allow a reduced EPZ designation, relative to an SMR or larger plant, given the smaller source term of radionuclides (some MMR concepts propose that the EPZ be limited to the site boundary). We will work within the evolving regulatory framework to establish appropriate emergency plans and security measures for our units. |
