The Company and Description of Business	THE COMPANY AND DESCRIPTION OF BUSINESS Energy Fuels Inc. and its subsidiary companies (collectively, the “Company”, “Energy Fuels” or “our”) produce several of the critical materials essential to United States (“U.S.”) energy security and other advanced technologies, including uranium, vanadium, Rare Earth Elements (“REEs”) and heavy mineral sands (“HMS”), in an effort to strengthen domestic supply chains and reduce reliance on foreign‑controlled sources. The White Mesa Mill (the “White Mesa Mill” or the “Mill”), located in Utah, is a key asset strengthen domestic supply chains due to its ability to process uranium, vanadium, REE products, and, potentially, radioisotopes. Uranium is used as fuel for nuclear power generation. The Company is engaged in conventional and in situ recovery (“ISR”) uranium exploration, evaluation, permitting (as applicable), extraction, recovery and sale of uranium from its mineral properties primarily located in the U.S. The Company’s Pinyon Plain, Whirlwind, La Sal, Bullfrog, Arizona Strip and Roca Honda projects are U.S.-based conventional uranium mining projects located on the Colorado Plateau and within trucking distance of the Mill. The Sheep Mountain Project is a uranium project located in Wyoming, U.S. As of March 31, 2026, the Company is producing mineralized material at its Pinyon Plain, La Sal and Pandora projects, as well as exploration drilling and analysis activities at its Pinyon Plain and Nichols Ranch projects. Other conventional uranium mining projects were on standby, under evaluation for future mining and related activities and/or in various stages of permitting. The Company’s Nichols Ranch Project (inclusive of the Jane Dough and Hank satellite deposits) is an ISR uranium project located in Wyoming, U.S. The Company also produces vanadium pentoxide (“V₂O₅”) as a co‑product of uranium recovery at the Mill from certain of its Colorado Plateau properties and, at times, from solutions recovered from the Mill’s tailings impoundment system, each as market conditions warrant. The Company conducts a uranium recycling program, which includes the processing of uranium from uranium‑bearing materials not derived from natural or native ores (“Alternate Feed Materials”), the recycling of tailings solutions, and other activities associated with the recovery of uranium, vanadium and potentially other metals and radionuclides. In addition, the Company is evaluating the potential to recover radioisotopes from its existing uranium processing streams at the Mill for use in targeted alpha therapy (“TAT”) medical treatments. REEs are used to manufacture permanent magnets for electric vehicles (“EVs”), defense systems, wind turbines, robotics and other clean energy and advanced technologies. The Company has advanced REE separation capabilities at the Mill to produce both ‘light’ and ‘heavy’ separated REE oxides. Additionally, the Mill has produced separated neodymium/praseodymium (“NdPr”) at commercial scale. Additionally, the Mill has produced on-spec dysprosium (“Dy”) oxide and terbium (“Tb”) oxide at the Mill at pilot scale. The Company is piloting samarium (“Sm”) oxide successfully at the Mill. NdPr, Dy, Tb and Sm are REEs that are classified as critical minerals in the U.S. The Company’s HMS projects contain titanium, zirconium and monazite. Titanium, which is produced from ilmenite and rutile, is used for aircraft engines and frames, spacecraft components, medical devices, pigments and other industrial and consumer goods uses. Zirconium is used for fuel rod cladding and reactor components for nuclear power plants, high-temperature parts in jet engines and spacecraft, metal alloys, ceramics, and abrasives and other uses in the medical field and chemical industry. The monazite is expected to provide feed for the Mill for the recovery of REEs and uranium. The Company’s REE/HMS projects include the Vara Mada REE and HMS project in Toliara, Madagascar (the “Vara Mada Project,” formerly known as the Toliara Project), which is a permitting/development stage property for the potential production of HMS products that would be sold into the commercial HMS product market while the associated monazite would be used as a feedstock ore for production of REEs and uranium at the Mill. The Company also owns the Bahia REE and HMS project in Brazil (the “Bahia Project”), which is an exploration/permitting stage property for the potential production of heavy mineral concentrate (“HMC”) that would be sold into the commercial HMC market while the associated monazite is expected to be used as a feedstock ore for the recovery of REEs and uranium at the Mill. The Company has a joint venture (the “Donald Project JV”) with Astron Corporation Limited (“Astron”) to jointly develop and operate the Donald REE and HMS Project in Australia (the “Donald Project”), which is a fully permitted development stage property also for the potential production of HMC that would be sold into the commercial HMC market while the associated monazite is expected to be used as feedstock ore for the recovery of REEs and uranium at the Mill. As of March 31, 2026, the Company is a “production stage issuer,” as defined by Subpart 1300 of Regulation S‑K, because it is engaged in the material extraction of Mineral Reserves on at least one material property. Proposed Acquisition of Australian Strategic Materials Limited The Company entered into a definitive agreement on January 20, 2026, as amended on March 12, 2026, to acquire 100% of the issued share capital of Australian Strategic Materials Limited (“ASM”) by way of a scheme of arrangement under Australian law. ASM is an Australian-based critical materials company with REE mining, processing, and metallization assets, including the Dubbo Project in New South Wales, a metallization and alloying facility in South Korea and plans to potentially construct a metallization and alloying facility in the U.S. Under the terms of the transaction, ASM shareholders will be entitled to receive 0.053 Common Shares (or CHESS Depositary Interests) for each ASM ordinary share held, and up to AUD$0.13 per ASM share in cash, subject to customary conditions. ASM option holders are expected to receive cash consideration of AUD$0.50 per option under a concurrent option scheme of arrangement. The transaction remains subject to court, regulatory and shareholder approval under the Australian scheme of arrangement process. Australian foreign investment approval has been obtained. The Company expects the transaction to close as early as July 2026.
