 gas turbines operate far lower. Based on annual data (2015-2024) from the EIA, single cycle gas turbines have an average capacity factor of 13.9% and below but combined cycle turbines have a capacity factor of 60.5% and below. In contrast, nuclear plants consistently deliver a capacity factor of approximately 90–95% according to the EIA, the highest of any large-scale energy source. Due to their lower capacity factor, natural gas operators must overbuild generation capacity and rely on redundant peaking or standby plants, typically simple-cycle gas turbines or diesel generators, to ensure grid reliability during demand surges or maintenance outages. In contrast, a single Hadron Halo is designed to provide continuous, around-the-clock baseload power without requiring such backup capacity. We expect to compete where customers want resilient, baseload power and to eliminate carbon emissions where gas delivery is constrained, such as in remote areas. We believe that the Hadron Halos, once at scale, will be able to produce power at a similar or lower cost than combined-cycle gas, and without fuel price risk or emissions. |

| • |     | Renewables Plus Storage: Large-scale solar and wind farms coupled with battery storage are the leading clean energy alternatives to nuclear energy. Costs for solar and wind power have declined significantly; industry data estimates that costs of unsubsidized utility solar can range from $38-$78/MWh and costs of onshore wind power range from $37-$86/MWh in the U.S.. However, such figures represent the intermittent power output inherent in renewable energy generation, as discussed above. When four-hour battery storage is added to provide more continuous power, the effective cost rises. Recent analyses show that utility solar power coupled with energy storage can range roughly between $50-$130 per MWh (unsubsidized), depending on storage duration and region. Even at those costs, renewables (plus storage) struggle to deliver true 24/7 reliability, especially for multi-day periods without sun or wind. The Hadron Halos will be able to provide steady baseload power and thus can complement or replace renewable energy (plus storage) solutions for customers who cannot tolerate intermittent power output. |

| • | Other Advanced Nuclear Developers: We are one of several companies developing advanced nuclear reactors, though design approaches among these companies differ greatly. Many of our competitors are focusing on larger modular reactors in the 50-300 MWe range, often targeting utility-scale electricity generation to replace conventional power plants. Examples include developers of
