| sunlight, the capacity factor of wind and solar farms are heavily influenced by season and geographic location, with average capacity factors often in the 25%-35% range. In comparison, U.S. nuclear power plants are designed to run at or near full output with an average capacity factor of approximately 93%, the highest capacity factor of any major energy source according to the U.S. Energy Information Administration (the “EIA”). This reliable around-the-clock output makes nuclear energy well suited to provide baseload power, which represents the minimum, steady level of electricity demand on a grid that must be met to ensure a reliable and consistent power supply. Power generation from renewables, on the other hand, requires either overbuilding capacity (such as gas turbines) or adding energy storage to achieve similar reliability due to intermittency, with solar having a 23.4% capacity factor and wind having a 34.3% capacity factor. |

| • |     | Energy Storage Costs: As noted above, in order to supply 24/7 power using intermittent renewables like wind and solar energy, large-scale energy storage must be added to these sites. Battery energy storage systems enable energy from renewables to be stored and released when power is needed most. Current battery storage systems are expensive. Grid-scale battery systems today cost approximately $200–$400 per kWh of storage capacity. Incorporating sufficient battery capacity to provide energy during low-output times, such as nights and multi-day lulls in wind speed, can substantially raise the levelized cost of renewable energy. Other energy storage solutions (such as pumped hydropower) are geographically limited to regions with significant elevation differences between two reservoirs. These factors make it challenging for renewable energy sites (including their energy storage requirements) to fully replace firm power plants without significant cost or overbuild. |

We believe MMRs like ours are uniquely positioned to address these limitations. The Hadron Halo will offer the high capacity factor and reliability of conventional nuclear energy packaged in a modular, small-scale design. By operating continuously at full power and requiring minimal land, MMRs can complement renewable energy production by providing carbon-free baseload power in locations or applications where large plants or vast solar/wind farms are impractical. We expect growing demand for “always-on”clean power that nuclear energy can provide. We believe that the Hadron Halo can meet this demand and will support critical and growing energy needs,
