Investing in a Sustainable Clean Energy Future with 10 Optioned Uranium Properties From Our Strategic Partner Denison Mines CORPORATE PRESENTATION January 2026 NASDAQ: FMST CSE: FAT Who Are We? Foremost Clean Energy is a rapidly growing North American uranium and lithium exploration company dedicated to advancing the clean energy economy. Our projects consist of 10 prospective uranium properties strategically located within the world-renowned Athabasca Basin, totaling over 330,000 acres. With drill-ready targets on identified conductors on important structural trends and proximal discoveries, our portfolio is well-positioned to capitalize on the growing demand for uranium as a crucial component of a sustainable energy future. We also maintain upside potential through a secondary portfolio of lithium projects with significant past drilling spanning 50,000+ acres primed for long-term development NASDAQ: FMST | CSE: FAT 3 Corporate Overview Corporate Overview Extensive Uranium Asset Portfolio: Highly attractive diversified uranium exploration portfolio with a total of 10 properties spanning over 330,000 acres on 45 claims, with years of completed historic exploration and inherited data Proven Mining Jurisdiction and Prolific Uranium Region : Premier assets located in the Athabasca Basin in northern Saskatchewan, Canada, with robust infrastructure and known to host some of the world's richest uranium deposits producing ~15% of world's primary uranium supply Strong Macro Tailwinds: Positioned to benefit from powerful uranium demand drivers including 30+ nations tripling nuclear capacity by 2050 and new U.S. nuclear energy directives, amid a projected period of sustained structural uranium supply shortage Denison Mines Corp : Denison isn't just Foremost largest shareholder, they have built a best-in-class team providing technical, operating and corporate support, with two board seats providing guidance, including Denison's own President and CEO Key Advantage: Once Foremost establishes a deposit and with Denison advancing Canada's first ISR uranium mine (2028 projected construction), could uniquely positions to bypass traditional delays and accelerate into supply constraint uranium market Tight Float and Aligned Incentives : Foremost Management and Board holds 4.65% of the company's shares outstanding, with Denison Mines holding 17.06% for a combined 21.71% ownership working towards building shareholder value Secondary Lithium Upside : Five Canadian lithium projects spanning 55,000+ acres with long-term development potential NASDAQ: FMST | CSE: FAT 4 Foremost and Denison Where Vision Meets Value Advantageous Position A highly sough-out position provided by Denison to advance underdeveloped properties and maximize untapped potential Significant Endorsement A groundbreaking collaboration with a significant and esteemed producer and developer within the uranium industry Access Denison is projected to have first ISR mine producing by 2028.
