IsoEnergy Ltd. Announces
$50 Million Bought Deal Financing
All monetary amounts are expressed in Canadian
Dollars, unless otherwise indicated.
Toronto, January 20, 2026 – IsoEnergy
Ltd. (TSX:ISO, NYSE American:ISOU) (the “Company” or “IsoEnergy”) is pleased to announce it has
entered into an agreement with a syndicate of underwriters (the “Underwriters”), pursuant to which the Underwriters
have agreed to purchase, on a bought deal basis, 3,333,400 common shares of the Company (“Common Shares”) at a price
of C$15.00 per Common Share (the “Offering Price”) for gross proceeds of C$50,001,000 (the “Offering”).
The Company has agreed
to grant the Underwriters an over-allotment option to purchase up to an additional 500,010 Common Shares at the Offering Price, exercisable
in whole or in part, at any time and from time to time on or prior to the date that is 30 days following the closing of the Offering to
cover over-allotments, if any, and for market stabilization purposes. If this option is exercised in full, an additional C$7,500,150 in
gross proceeds will be raised pursuant to the Offering and the aggregate gross proceeds of the Offering will be C$57,501,150.
The Common Shares will
be offered by way of a prospectus supplement to be filed in all of the provinces and territories of Canada, except Quebec and in the United
States on a private placement basis, and other jurisdictions outside of Canada and the United States provided that no prospectus filing
or comparable obligation arises. Access to the prospectus supplement and the corresponding base shelf prospectus and any amendment thereto
will be accessible within two business days under the Company’s profile on SEDAR+ at www.sedarplus.ca in accordance with securities
legislation relating to procedures for providing access to a base shelf prospectus, a prospectus supplement and any amendment thereto.
Concurrently with the
Offering, the Company intends to complete a non-brokered private placement (the “Concurrent Private Placement”) of
up to 1,666,666 Common Shares at a price of C$15.00 per Share with NexGen Energy Ltd. (“NexGen”) for aggregate gross
proceeds of up to approximately C$25,000,000. The Concurrent Private Placement is being completed to enable NexGen to maintain its pro
rata ownership interest in the Company at approximately 30% after giving effect to the Offering. The Common Shares to be issued pursuant
to the Concurrent Private Placement will be subject to a restricted hold period of four months and one day following the closing of the
Concurrent Private Placement. No commission or other fee is payable to the Underwriters in connection with the sale of Common Shares pursuant
to the Concurrent Private Placement.
The proceeds from the
Offering and the Concurrent Private Placement are expected to be used to fund the continued development and further exploration of the
Company's mineral properties, and for general corporate purposes.
The Offering is scheduled
to close on or about January 27, 2026 and is subject to certain conditions including, but not limited to, the receipt of all necessary
approvals to list the Common Shares on the required exchanges, which listings shall be conditionally approved prior to closing of the
Offering.
This press release
shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in any state
in which such offer, solicitation or sale would be unlawful. The securities being offered have not been, nor will they be, registered
under the United States Securities Act of 1933, as amended (the “U.S. Securities Act”) and may not be offered or sold in the
United States absent registration or an applicable exemption from the registration requirements of the U.S. Securities Act and applicable
state securities laws.

This press release contains “forward-looking
statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995 and “forward-looking
information” within the meaning of applicable Canadian securities legislation (collectively, referred to as “forward-looking
information”). Generally, forward-looking information can be identified by the use of forward-looking terminology such as “plans”,
“expects” or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”,
“forecasts”, “intends”, “anticipates” or “does not anticipate”, or “believes”,
or variations of such words and phrases or state that certain actions, events or results “may”, “could”, “would”,
“might” or “will be taken”, “occur” or “be achieved”. This forward-looking information
may relate to the Offering and the Concurrent Private Placement, including statements with respect to the completion of the Offering and
the Concurrent Private Placement and the anticipated closing dates thereof; the expected receipt of regulatory and other approvals relating
to the Offering and the Concurrent Private Placement; the expected proceeds of the Offering and the Concurrent Private Placement and the
anticipated use of the net proceeds therefrom; and any other activities, events or developments that the companies expect or anticipate
will or may occur in the future.
Forward-looking statements are necessarily
based upon a number of assumptions that, while considered reasonable by management at the time, are inherently subject to business, market
and economic risks, uncertainties and contingencies that may cause actual results, performance or achievements to be materially different
from those expressed or implied by forward-looking statements. Such assumptions include, but are not limited to, the assumptions that
IsoEnergy will complete the Offering and the Concurrent Private Placement in accordance with terms and conditions of the relevant agreements;
that the Company will receive the required regulatory and other approvals related to the Offering and the Concurrent Private Placement;
that the Company will satisfy, in a timely manner, any conditions precedent to completion of the Offering and the Concurrent Private Placement;
the price of uranium; and that general business and economic conditions will not change in a materially adverse manner. Although IsoEnergy
has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking
information, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance
that such information will prove to be accurate, as actual results and future events could differ materially from those anticipated in
such statements. Accordingly, readers should not place undue reliance on forward-looking information.
Such statements represent the current views
of IsoEnergy with respect to future events and are necessarily based upon a number of assumptions and estimates that, while considered
reasonable by IsoEnergy, are inherently subject to significant business, economic, competitive, political and social risks, contingencies
and uncertainties. Risks and uncertainties include, but are not limited to the following: a material adverse change in the timing of and
the terms and conditions upon which the Offering and the Concurrent Private Placement are completed; the inability to satisfy or waive
all conditions to completion of the Offering or the Concurrent Private Placement; the failure to obtain regulatory approvals in connection
with the Offering or the Concurrent Private Placement; regulatory determinations and delays; stock market conditions generally; demand,
supply and pricing for uranium; and general economic and political conditions in Canada, the United States and other jurisdictions where
the applicable party conducts business. Other factors which could materially affect such forward-looking information are described in
the risk factors in IsoEnergy’s most recent annual management’s discussion and analysis or annual information form and IsoEnergy’s
other filings with the Canadian securities regulators which are available under the Company’s profile on SEDAR+ at www.sedarplus.ca.
