KPMG LLP is the independent registered public accounting firm.
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 Ltd. has completed a bought deal equity financing, selling 3,833,410 common shares at C$15.00 per share for gross proceeds of approximately C$57.5 million. The financing, led by a syndicate of underwriters including Stifel Canada, Canaccord Genuity Corp. and Jett Capital Advisors, LLC, included the full exercise of the over-allotment option. 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. is raising new equity through a C$50,001,000 bought deal financing, selling 3,333,400 common shares at C$15.00 each to a syndicate of underwriters. The company has also granted an over-allotment option for up to 500,010 additional shares at the same price, which would increase gross proceeds by C$7,500,150 to a total of C$57,501,150 if fully exercised.
Alongside this, IsoEnergy plans a non-brokered private placement of up to 1,666,666 common shares at C$15.00 per share with NexGen Energy Ltd. for up to C$25,000,000, allowing NexGen to maintain about a 30% ownership stake after the financing. IsoEnergy expects to use the combined proceeds to continue developing and exploring its uranium and vanadium mineral properties and for general corporate purposes, with closing targeted on or about January 27, 2026, subject to listing and regulatory approvals.
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.
The Hurricane deposit currently has a Mineral Resource of 48.6 million pounds U3O8 at 34.5% U3O8 in the Indicated category and 2.7 million pounds U3O8 at 2.2% U3O8 in the Inferred category. Drilling will target North and South trends around Hurricane and a broader target area to the east where prior holes intersected uranium mineralization, leveraging existing infrastructure and relatively shallow mineralization around 325 metres depth.
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. Over a 25‑month period, the company can issue common shares, warrants, units, unsecured debt securities (including convertible debt), and subscription receipts, either individually or in combination, with final terms set in future prospectus supplements.
IsoEnergy notes that net proceeds from future offerings may fund drilling programs, economic studies on key projects such as Larocque East and the Tony M Mine, mine equipment for Utah projects, acquisitions, and general working capital. The filing highlights that the company has had negative operating cash flow and remains dependent on external financing, and that most securities other than the common shares may not have an active trading market.
The prospectus also emphasizes significant risk factors, including dilution from future financings, uranium price volatility, extensive regulatory oversight, Indigenous and Aboriginal rights considerations, climate-related operational risks, and potential impacts from evolving international trade and nuclear policies.
