Isoenergy SEC Filings

IsoEnergy Ltd. completed a non-brokered concurrent private placement with NexGen Energy Ltd. for C$25,000,005. The company issued 1,666,667 common shares at C$15.00 per share. Proceeds are expected to fund continued development and exploration of its mineral properties and for general corporate purposes.

The financing was structured so NexGen can maintain its pro rata ownership at approximately 30% after a separate bought deal offering. The NexGen investment is treated as a related party transaction under MI 61-101, with IsoEnergy relying on exemptions because the deal value is below 25% of its market capitalization.

IsoEnergy plans to use the proceeds to continue developing and further exploring its uranium and vanadium mineral properties and for general corporate purposes. The company also expects to close a previously announced non-brokered concurrent private placement with NexGen Energy Ltd. on or about the same date.

IsoEnergy Ltd. has started its 2026 winter diamond drilling program at the Larocque East project in Canada’s Athabasca Basin, which hosts the high-grade Hurricane uranium deposit. The campaign includes approximately 5,200 metres of drilling in up to 13 holes aimed at expanding the Hurricane resource and testing new greenfield targets up to three kilometres east along trend.

IsoEnergy Ltd. has filed a Form F-10 base shelf prospectus to register up to $250,000,000 of mixed securities that may be sold from time to time.
