Nexgen Energy (NXE) Corporate presentation summary

Strategic project overview

• Rook I is under construction and set to become the world's largest uranium source under development, with the capacity to supply about 20% of global and over 50% of western primary uranium supply upon completion.

• The Arrow deposit features ultra-high grades, robust after-tax cash flow potential, and expansion opportunities, positioning it as a world-class asset.

• The project uses conventional hard-rock mining, with a unique geology that enables efficient, low-cost, and environmentally responsible operations.

• All processed waste will be stored underground, eliminating surface tailings and setting a new global standard for environmental mine management.

• Rook I is supported by formal Indigenous community agreements and strong local partnerships, with significant local hiring and procurement.

Market dynamics and uranium demand

• Global nuclear capacity is set to triple by 2050, with 80 reactors under construction and AI-driven power demand accelerating uranium requirements.

• Uranium supply is structurally constrained, with a projected 335 Mlbs annual deficit by 2040 and supply unable to respond quickly due to long mine development timelines.

• 85% of all uranium mined since 1945 will be consumed again in the next 25 years, requiring new supply on an unprecedented scale.

• OECD countries rely on foreign sources for 70% of uranium demand, with less than 1% produced domestically in the US, UK, and Europe.

• Higher, sustained uranium prices are necessary to incentivize new production, as price increases alone have not triggered sufficient supply response.

Project execution and financials

• Construction began in June 2026 after receiving final federal approval, with major infrastructure and site works progressing on schedule.

• Rook I's high-grade ore allows for minimal material movement, reducing environmental impact and operational costs.

• The project is fully funded with C$970M in cash and multiple financing options, supporting a clear path to production.

• Projected after-tax free cash flow positions the company among the top global mining companies, with significant leverage to rising uranium prices.

• Sales commitments total 11.7 million lbs at market-related pricing, with a strategy designed to maximize profitability as uranium prices rise.
