DEEP ISOLATION NUCLEAR INC

Deep Isolation (OTCQB: DBHL) is the first company to undertake development of technologies for nuclear waste disposal in deep boreholes. When commercialized, Deep Isolation’s solution will offer a unique solution to help countries identify, plan for and complete the necessary steps to dispose of their nuclear waste inventories. With over 100 patents issued to date, Deep Isolation’s technology is being designed to leverage proven drilling practices to allow safe isolation of waste deep underground in horizontal, vertical, or slanted borehole repositories. Deep Isolation’s Universal Canister System was developed through a three-year project funded by the U.S. Department of Energy’s Advanced Research Projects Agency - Energy and is engineered to support integrated management of spent fuel and high-level radioactive waste from legacy and advanced reactors across storage, transportation, and eventual disposal. In January 2026, Deep Isolation launched a full-scale, at-depth deep borehole Commercialization Pilot for its solution at Cameron, Texas, in collaboration with the Deep Borehole Demonstration Center, Halliburton (NYSE: HAL), Amentum (NYSE: AMTM), NAC International, and Occlusion Nuclear Solutions.
