Energy Fuels Acquires RadTran LLC as A Further Step Toward Addressing the Global Industry Need For Medical Radioisotopes in Emerging Cancer Treatments

Acquisition intended to enhance Energy Fuels' current capabilities and support announced plans for medical isotope development.

LAKEWOOD, Aug. 19, 2024 - Energy Fuels Inc. (NYSE American: UUUU) (TSX: EFR) ("Energy Fuels"), an industry leader in uranium and rare earth elements ("REE") production for the energy transition, today announces the August 16, 2024 acquisition (the "Acquisition") of RadTran LLC ("RadTran"), a private company specializing in the separation of critical radioisotopes, to further Energy Fuels' plans for development and production of medical isotopes used in cancer treatments. RadTran's expertise includes separation of radium-226 ("Ra-226") and radium-228 ("Ra-228") from uranium and thorium process streams. This strategic acquisition is expected to significantly enhance Energy Fuels' planned capabilities to address the global shortage of these essential isotopes used in emerging targeted alpha therapies ("TAT") for cancer treatment.

Mark Chalmers, President and CEO of Energy Fuels said, "With this Acquisition, we will be combining our unique processing capabilities at the White Mesa Mill, the only permitted and operating uranium mill in the United States, with over 40 years of chemical and metal separations experience, with RadTran's intellectual property and medical isotope experience in radionuclide separation and concentration, which we believe will position Energy Fuels to be a leader in this developing industry.

"Additionally, what I find exciting about this initiative is that Energy Fuels has the potential to recover valuable isotopes from its existing process streams, thereby recycling back into the market material that would otherwise be lost to disposal and repurposing it for use in producing life-saving cancer treatments.

"And our current R&D activities are being conducted using existing Mill facilities without the need for capital improvements of any significance. Capital development for future commercial production capabilities, upon successful production at the R&D level, would be expected to be supported by future offtake agreements for radium production."

Since July 2021, Energy Fuels and RadTran have been working under a Strategic Alliance Agreement to evaluate the feasibility of recovering Ra-226 and Ra-228 from existing uranium process streams at Energy Fuels' White Mesa Mill in Utah (the "Mill"). Recovered Ra-226 and Ra-228 would be made available to the pharmaceutical industry and others to enable the production of actinium-225 ("Ac-225"), lead-212 ("Pb-212") and potentially other leading medically attractive TAT isotopes. These isotopes are critical components in the development of targeted alpha therapies, which offer promising new treatments for various cancers. The global shortage of Ra-226 and Ra-228 currently presents itself as a significant barrier to the advancement and commercialization of these therapies.

Energy Fuels received regulatory approval and licensing in 2023 for the concentration of R&D quantities of Ra-226 at the Mill and is currently completing engineering on its research and development ("R&D") pilot facility for Ra-226 production. During 2024, Energy Fuels plans to set up the first stages of the pilot facility and expects to produce R&D quantities of Ra-226 for testing by end-users of the product. Upon successful production of R&D quantities of Ra-226, Energy Fuels plans to develop capabilities at the Mill for the commercial-scale production of Ra-226 and potentially Ra-228 in 2026-2028, conditional on completion of engineering design, securing sufficient offtake agreements for final radium production, and receipt of all required regulatory approvals.

Under the Acquisition, the purchase price payable by Energy Fuels to the owners of RadTran consists of (all dollar amounts in US$): (i) on closing, $1.5 million in cash, $1.5 million in Energy Fuels common shares ("Common Shares") and the grant of a 2% royalty on future revenues from the sale of produced radium, as well as certain other contractual commitments; and up to an additional $14 million in cash and Common Shares based on the satisfaction of a number of performance-based milestones, including achieving initial production, securing suitable offtake agreements to justify commercial production and reaching commercial production.

In addition, as part of the Acquisition, Saleem Drera PhD, President and CEO of RadTran, will join Energy Fuels as Vice President of Radioisotopes, Radiological Systems, and Intellectual Property. In this role, Dr. Drera will lead Energy Fuels' efforts to integrate RadTran's proprietary technology, which includes a number of patents, pending patents, trade secrets and know-how relating to efficient separation of Ra-226 and Ra-228 from process streams, and drive innovation in the production of medical radioisotopes.

The demand for Ra-226 and Ra-228 is underscored by the extensive clinical research currently underway. More than 30 clinical trials are evaluating Ac-225, a product of Ra-226 and a crucial component of targeted alpha therapies, highlighting the urgent need for reliable isotope supply. Notably, several of these trials have reached final pre-approval stage (phase 3) targeting neuroendocrine tumors and leukemia, with many more earlier stage trials already initiated to address common cancers including prostate cancer.

Critically, a shortfall in Ac-225 production (for which Ra-226 is the limiting raw material), is now delaying trials and challenging the transition to full commercial and clinical availability of these drugs. Energy Fuels intends to step in to alleviate this supply bottleneck and support development of this important new class of life-saving cancer therapies.

Saleem Drera, President and CEO of RadTran, and now Vice President Radioisotopes, Radiological Systems and Intellectual Property of Energy Fuels, said, "At RadTran, we are proud to be a part of the Energy Fuels team. The White Mesa Mill's facilities, permits and licenses, and Energy Fuels' years of experience are Ideally suited to employ RadTran's Technology. Furthermore, we have been impressed with their successful endeavors to separate and concentrate uranium, vanadium and rare earth elements in a manner that adheres to the strictest standards of protection of human health, safety and the environment."

ABOUT ENERGY FUELS

Energy Fuels is a leading US-based critical minerals company. The Company, as the leading producer of uranium in the United States, mines uranium and produces natural uranium concentrates that are sold to major nuclear utilities for the production of carbon-free nuclear energy. Energy Fuels recently began production of advanced rare earth element ("REE") materials, including mixed REE carbonate in 2021, and commenced production of commercial quantities of separated REEs in 2024.
