FOREMOST CLEAN ENERGY TO ISSUE SHARES TO DENISON MINES CORP. UNDER INVESTOR RIGHTS AGREEMENT AND STRENGTHEN ITS TREASURY BY OVER $1 MILLION

Further to Foremost Clean Energy Ltd.'s amended and restated investor rights agreement dated July 23, 2025 (the Denison IRA), between the company and Denison Mines Corp., Denison notified the company of its intention to subscribe for common shares pursuant to its equity participation right relating to certain share issuances completed by the company (see press release June 14, 2025). The share issuances were related to warrant exercises and for property payments including the company's final property payment for its Jean Lake lithium/gold property (see press release dated July 16, 2025).

In connection with the exercise of the equity participation right, the company will issue 485,000 common shares to Denison at a price of $2.20 per share for aggregate consideration of $1,067,000. The issuance is in accordance with the Denison IRA and has been approved by the Canadian Securities Exchange (CSE). Following completion of the private placement, Denison will own approximately 19.17 per cent of Foremost's common shares outstanding. The common shares that will be issued pursuant to the private placement are subject to a hold period of four months and one day from the date of issuance in accordance with applicable securities laws. A copy of the Denison IRA is available on the company's SEDAR+ profile.

"We are very pleased with Denison's continued financial and operational support, which underscores its commitment to our unique collaboration," said Jason Barnard, president and chief executive officer of Foremost. "Having a strategic ally of Denison's calibre exercise its participation rights is a strong validation of our shared vision and the prospective nature of our assets. This additional capital strengthens our treasury at an ideal time, enabling us to continue executing our planned exploration. Our primary focus remains on advancing our Athabasca basin portfolio and delivering on our operational objectives for the year."

The proceeds from the private placement will be used to advance exploration for the company's 330,000 acres/133,500-plus-hectare Athabasca basin uranium portfolio and for general corporate purposes.

About Foremost Clean Energy Ltd.

Foremost Clean Energy is a rapidly growing North American uranium and lithium exploration company. The company holds an option from Denison to earn up to a 70-per-cent interest in 10 prospective uranium properties (with the exception of the Hatchet Lake, where Foremost is able to earn up to 51 per cent), spanning over 330,000 acres in the prolific, uranium-rich Athabasca basin region of Northern Saskatchewan. As the demand for carbon-free energy continues to accelerate, domestically mined uranium and lithium are poised for dynamic growth, playing an important role in the future of clean energy. Foremost's uranium projects are at different stages of exploration, from grassroots to those with significant historical exploration and drill-ready targets. The company's mission is to make significant discoveries alongside and in collaboration with Denison through systematic and disciplined exploration programs. Foremost also has a portfolio of lithium projects at varying stages of development, which are located across 55,000-plus acres in Manitoba and Quebec.
