IsoEnergy to lift Premier American Uranium stake to 22% as DISA Uranium completes US$5 million investment

IsoEnergy Ltd. has agreed to acquire 13,642,775 common shares of Premier American Uranium Inc. from Sachem Cove Opportunity Fund LP, a transaction that will lift IsoEnergy's ownership in the uranium explorer to approximately 22%. The consideration is 387,491 newly issued IsoEnergy common shares, priced at a deemed value of $11.763 each, for aggregate consideration of roughly $4.56 million. Closing remains subject to customary conditions, including approval from the Toronto Stock Exchange.

Simultaneously, DISA Uranium Corporation, the technology-enabled uranium company formed earlier in 2026 through a joint venture between IsoEnergy and DISA Technologies, completed a US$5 million strategic equity investment in Premier American Uranium. The two transactions together deepen the strategic ties between Premier American Uranium and its largest institutional backers and add to IsoEnergy's concentrated exposure to U.S. uranium assets at a time when domestic uranium supply is under heightened focus.
