IsoEnergy Ltd. (NYSE American: ISOU; TSX: ISO) reported on August 19, 2026 that it has closed its previously announced transaction with DISA Technologies, Inc. to form DISA Uranium Corporation, a new, privately held U.S. uranium company. IsoEnergy contributed its Utah portfolio of permitted, past-producing conventional uranium mines, the Tony M, Daneros, and Rim mines, along with the Sage Plain and Flatiron projects, to DISA Uranium in exchange for 1,677,350 shares of the new company’s common stock. The deal was first announced on August 4, 2026; this release confirms the transaction has now formally closed.
A Related but Separate Company
DISA Uranium is not publicly traded and has no stock ticker. Concurrent with closing, DISA Uranium also closed a US$105 million private placement financing, with IsoEnergy itself investing $33 million of that total. Combined with its Utah mine contribution, IsoEnergy now owns approximately 33% of DISA Uranium on a fully diluted basis and is its largest shareholder. Other investors in the financing include Tembo Capital, BHP Ventures, Galvanize Climate Solutions, Valor Equity Partners, Evok Innovations, Halliburton Labs, and Veriten. The two companies remain closely linked beyond ownership: DISA Uranium’s seven-member board includes IsoEnergy’s board chairman, Richard Patricio, and IsoEnergy’s CEO, Philip Williams, alongside DISA Technologies executives Greyson Buckingham and Scott Saxberg, Tembo Capital partner George Pyper, Marty Reed, and former U.S. Nuclear Regulatory Commission Commissioner Jeffrey Merrifield. Readers should understand IsoEnergy retains a significant ongoing financial and governance interest in DISA Uranium rather than having made a clean, arm’s-length divestment of these assets.
What DISA Uranium Plans to Do
DISA Uranium is combining IsoEnergy’s Utah mines with DISA’s proprietary HPSA technology, along with an existing mine remediation and recovery business. The company holds what it describes as the only U.S. Nuclear Regulatory Commission license to treat and recover uranium from abandoned uranium mine waste across multiple sites, meaning it can process leftover material from old, previously mined sites rather than only mining new ore. DISA Uranium’s stated strategy has three parts: applying that waste-recovery technology, restarting conventional uranium production at its now-acquired Utah mines, with the Tony M Mine flagged as a near-term priority, and building domestic uranium processing capacity. None of these are guaranteed outcomes; recovering uranium economically from mine waste and restarting previously idled conventional mines both depend on technical, regulatory, and market factors that remain to be proven out.
What This Means for IsoEnergy
For IsoEnergy, the transaction converts a portfolio of past-producing but currently non-operating mines into an equity stake in a newly capitalized company focused specifically on developing them, alongside a broader portfolio IsoEnergy continues to hold directly, including its Larocque East project in Canada’s Athabasca Basin. CEO Philip Williams described the move as unlocking value from the Utah assets while giving IsoEnergy exposure to what the company calls a differentiated U.S. uranium platform, though as a minority shareholder, IsoEnergy’s future returns from these assets now depend on DISA Uranium’s execution rather than being under IsoEnergy’s direct operational control.
