Innovation in our reactor design and systems is a critical asset, and we actively protect our intellectual property (“ IP”). We pursue a strategy of patenting key inventions, securing trademarks, and maintaining trade secrets. As of the date of this filing, Hadron Energy has filed for or secured patent protection on several aspects of our technology, including:

| • |     | Patents on Technological Inventions: We have two pending utility patent applications covering the Hadron Halo. The first covers the invention of our Hadron Halo design, describing a compact design that |

| integrates the steam generator within the reactor pressure vessel and is coupled with a passive suppression pool for heat removal and shielding. The second patent covers the novel nuclear reactor core design itself, which is engineered to improve neutron economy and fuel efficiency in a small reactor, enabling a long operational life and high fuel burnup from a compact-sized core. |

| • |     | Patents on Aesthetic Designs: We have filed two U.S. design patent applications which cover the ornamental appearance of claimed nuclear microreactors, including the Hadron Halo module and enclosure. If granted, these patents would prevent others from making, using, selling, or importing products that create a substantially similar overall visual impression as the claimed designs. |

| • |     | Patents on Digital Twin and Automated Control Systems: Our use of advanced sensors, digital twin simulation
