ISOENERGY COMPLETES C$23 MILLION BOUGHT DEAL PRIVATE PLACEMENT

IsoEnergy Ltd. has closed its previously announced bought deal brokered private placement announced on Jan. 18, 2024, pursuant to which the company sold 3.68 million federal flow-through common shares of the company (the premium FT shares) at an offer price of $6.25 per premium FT share, for aggregate gross proceeds of $23-million, which includes the full exercise of the underwriters' overallotment option. The offering was conducted by a syndicate of underwriters, co-led by Eight Capital and Haywood Securities Inc., as joint bookrunners, and including Canaccord Genuity Corp., PI Financial Corp., Red Cloud Securities Inc. and TD Securities Inc.

The proceeds from the issuance of the premium FT shares are expected to be used to incur eligible Canadian exploration expenses (CEE) as defined in the Income Tax Act (Canada) (the ITA) that will qualify as flow-through critical mineral mining expenditures as defined in the ITA, after the closing date and on or prior to Dec. 31, 2025, in the aggregate amount of not less than the total amount of the gross proceeds raised from the issuance of premium FT shares. IsoEnergy will renounce the CEE (on a pro rata basis) to the applicable subscriber of premium FT shares with an effective date of no later than Dec. 31, 2024, in accordance with the ITA. The proceeds from the offering are expected to be used for exploration of the company's Athabasca basin portfolio, including the Larocque East project and Hawk project, and for exploration of the company's Quebec properties.

The premium FT shares issued pursuant to the offering are subject to a hold period of four months and one day under applicable Canadian securities laws.

In connection with the offering, the underwriters received a cash fee in an amount representing 6 per cent of the gross proceeds of the offering.
