Operational Update:

On September 2, 2025, the Company announced that its Dewey-Burdock Project, located in South Dakota, was approved for inclusion in the Fast-41 Program by the U.S. Federal Permitting Improvement Steering Council (“Permitting Council”) for expedited permitting review. This is a component of the implementation of President Trump’s Executive Order on Immediate Measures to Increase American Mineral Production. The Company’s Dewey-Burdock Project received its Source and Byproduct Materials License in 2014, from the Nuclear Regulatory Commission (“NRC”), now under timely renewal, and will work with the NRC as the lead agency for federal permitting. The Company’s objective is to advance the Dewey Burdock Project into development and operation utilizing the ISR uranium extraction process. Under the Executive Order, the Permitting Council identifies priority infrastructure and critical mineral projects to receive accelerated permitting review. The addition of the first South Dakota ISR project to the Fast-41 Program supports the domestic uranium production focus of the United States. This focus enables the development of essential clean energy, extracted through environmentally responsible ISR technology, to provide affordable, reliable domestic energy.

Non-GAAP Financial Measures

This press release contains non-GAAP financial measures. A “non-GAAP financial measure” is defined as a numerical measure of a company’s financial performance that excludes or includes amounts so as to be different than the most directly comparable measure calculated and presented in accordance with GAAP in the statements of income, balance sheets or statements of cash flows of the Company. The non-GAAP financial measures used within this press release are total cost of extracted pounds, uranium cost per extracted pound, total cost of extracted inventory and

uranium cost per extracted pound in inventory. Total cost of extracted pounds is the cost of sales less the cost of sales of purchased goods, which includes the aggregate purchase price of uranium sourced from purchased uranium. Uranium cost per extracted pound is the total cost of extracted pounds divided by the pounds of uranium extracted during the period. Total cost of extracted inventory is inventory less purchased uranium inventories. Uranium cost per pound of extracted inventory is the total cost of extracted inventory divided by pounds of extracted inventory. We consider the total cost of extracted pounds, uranium cost per extracted pound total cost of extracted inventory and uranium cost per pound of extracted inventory, including allocations of cash and non-cash costs, in evaluating the efficiency and cost-effectiveness of the Company’s extraction operations and overall cost structure. The presentation of non-GAAP financial measures should not be considered in isolation or as a substitute for reported results under U.S. GAAP, and may not be comparable to similarly titled measures used by other companies.
