Nexgen Energy (NXE) Corporate presentation summary

Strategic project overview

• Advancing the world's highest-grade, large-scale uranium project, Rook I, in Saskatchewan, Canada, with potential to supply ~20% of global uranium from a single mine based on the 2021 Feasibility Study.

• Project is fully permitted for construction, with major construction set to begin in summer 2026 following final federal approval in March 2026.

• Arrow deposit features reserves of 239.6 million lbs at 2.37% U3O8, with over 65% of measured & indicated resource at 15.9% U3O8, making it one of the most robust and economically resilient uranium deposits globally.

• Conventional hard-rock mining method in stable crystalline basement rock enables low operating costs, underground tailings storage, and minimal environmental impact.

• Project is positioned to deliver strong after-tax cash flow and is resilient across a range of uranium price scenarios.

Market dynamics and uranium demand

• Global nuclear capacity is set to increase by 18% by 2030, with over 30 countries pledging to triple nuclear capacity by 2050, driven by electrification and AI-related power demand.

• Uranium supply is projected to fall short, with a 335 million lbs annual deficit by 2040, requiring mine supply to more than triple from current levels.

• Supply response is slow due to long mine development timelines; price increases alone cannot close the gap, necessitating higher, sustained prices for decades.

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

Competitive and operational advantages

• High-grade deposit allows for minimal material movement: only 3 trucks per day feed the mill, reducing infrastructure and environmental impact.

• Underground tailings management eliminates surface tailings risk, setting a new global standard for environmental mine management.

• Flexible, market-related contracting strategy leverages rising uranium prices, with 10 million lbs in sales commitments to major utilities.

• Efficient capital allocation with industry-leading ratios of exploration/development spend to G&A, and low G&A as a percentage of market cap.
