     | Export Controls: Because we intend to market our reactors internationally, we must comply with U.S. export control laws governing nuclear technology. Specifically, 10 CFR Part 810 regulations (administered by the DOE) control the export of nuclear technical information and assistance, and the U.S. Department of Commerce’s Export Administration Regulations (EAR) cover hardware exports. We will ensure that any transfer of our technology or equipment abroad has the required government authorizations. Similarly, fuel or sensitive components may require specific export licenses and we will ensure that we meet all applicable regulatory requirements. Compliance with export control laws are built into our operating procedures in regulatory and compliance. |

| • |     | Environmental and Other Regulations: We are subject to environmental laws such as the National Environmental Policy Act (NEPA), which requires environmental reviews for major federal actions relating to our projects, such as NRC licensing or significant project involvement or funding from the DOE. We participate in the industry’s nuclear liability management under the Price-Anderson Act, which establishes a no-fault insurance framework for nuclear incidents. Additionally, the construction of our manufacturing facility, once underway, will require our compliance with state and federal environmental regulations on construction and waste. |

Government regulation permeates every aspect of our business and Hadron Energy is actively engaged with regulatory bodies to ensure efficient licensing and oversight of our Hadron Halo design, deployment, and operations. We have developed an internal compliance program to ensure we meet all applicable laws and 291

guidelines. Our compliance program includes periodic audits, staff training on nuclear regulatory compliance, and engagement with experienced regulatory counsel. With an evolving regulatory and policy framework, Hadron Energy monitors the legislative and regulatory landscape closely in order to adapt our business plans accordingly. For further discussion about regulatory requirements and oversight, please refer to the section of this proxy statement/prospectus titled “ Risk Factors—Risks Related to Our Business and Industry.” Fuel Supply A reliable and economical fuel supply chain is essential for our reactor operations. Our reactor cores utilize LEU+ fuel, enriched to between 5-10% U-235,which allows for longer core life and compact core size compared with conventional LWR fuel enriched to a maximum of 5 wt%. LEU+ fuel is much more widely available than alternative fuels such as HALEU or TRi-structuralISOtropic fuel (“ TRISO”), allowing us to take advantage of an established supply chain and achieve commercialization more efficiently with already qualified fuel. Key aspects of our fuel strategy and related considerations include:
