 small modular reactors (“SMRs”) using LWR designs and companies pursuing advanced concepts like sodium-cooled fast reactors, high-temperature gas reactors, or molten salt reactors. These projects typically require significant capital expenditures in the multi-billions of dollars to commercialize and build first plants and face lengthy licensing and construction timelines. By focusing on nuclear reactors at a micro scale (the DOE defines MMRs as single modules that produce less than 20 MWe per unit) and a simpler technology (light-water cooling, use of familiar fuels and design components), the Hadron Halo can reach the market faster and with less capital than our competitors. We also believe that Hadron Halos will be more easily deployable than those of our competitors and will be easier to transport and install than larger SMRs that, while modular in fabrication, still involve substantial on-site construction. Nonetheless, as the advanced nuclear field matures |

| in the coming decade, we expect to face competition for projects, funding, and talent from these companies. However, we believe that the Hadron Halo may fill a different market need than larger SMRs, and we may explore partnerships where our product can supplement larger-scale clean energy solutions. |

Overall, Hadron Energy’s differentiator is our focus on small, factory-fabricated MMRs that can be rapidly deployed with low upfront cost per unit. We are not aware of any competitor that combines all these attributes at the 10 MWe scale. By targeting niche and currently underserved markets (like off-gridindustrial power, data center campus power, or remote applications) rather than immediately competing head-to-headwith large power plants, we aim to carve out a unique space in the energy landscape. Our goal is to make the Hadron Halos a go-tosolution for reliable, carbon-free power where traditional power options fall short. Research and Development Continuous research, development, and testing (collectively, “ R&D”) are core to our company as we advance our reactor design toward commercialization. We currently have several active R&D programs and technical milestones, including:

| • | Reactor Core Design and Simulation: We will extensively test our design by using robust modeling and simulation to refine the reactor core and fuel system. This will leverage state-of-the-art neutronics codes, which model the nuclear properties of the core, and thermal-hydraulic codes, which model fluid mechanical and heat transfer effects during normal and accident conditions. These simulations will support our economic case by verifying the core’s ability to operate at the design power
