 Executive NRC is equally beneﬁcial for LEU+ designs Orders • Encourages “recycling” of validated DOE/DOD tests • Ability to negotiate pilot sitings on federal sites earlier (Trump 2025) • Eases siting on federal land for demonstration and validation • Streamlines the nuclear licensing and environmental • Hadron qualiﬁes under MMR guidance, accelerating ADVANCE Act review process the review process (2024) • Reduces ﬁnancial barriers and incentivizes new • Lowers licensing uncertainty and reduces technical advanced reactors and ﬁnancial risk • Quicker regulatory process for small, factory-built • Signiﬁcantly lower regulatory burden on Hadron’s Nuclear reactors like Hadron’s Regulatory application Commission • May potentially avoid lengthy environmental impact • Use of LEU+ fuel aligns safety and materials evaluations (NRC) with precedents reviews and other regulatory hurdles • Allocates HALEU, planning fuel supply base, backing • Eﬀorts signal a favorable policy orientation toward pilot deployments reactor projects Department of Energy (DOE) • DOE supply-chain and industrial base investments • Building out the fuel ecosystem, so reactor projects aren’t starved for fuel reduce risk for components, and infrastructure P. 9/23 FEDERAL SUPPORT FOR NUCLEAR

CONFIDENTIAL One Platform. Endless Energy Applications. Hadron’s micro modular reactors redeﬁne versatility—serving as both power plants and heat sources for a variety of sectors. By integrating electricity and process heat in one deployable system, Hadron will unlock new economic value, shorten project timelines, and accelerate the transition to sustainable energy infrastructure worldwide P. 10/23
