NexGen Energy is advancing the Rook I uranium project, now fully permitted and entering construction, with the potential to supply 20% of global uranium demand. NXE's valuation (~$8 billion) reflects optimism about Rook I's high-grade reserves, low costs, and leverage to rising uranium prices, but the project remains years from production. The company's flexible contract strategy maximizes exposure to future uranium price upside but introduces market risk and amplifies sensitivity to commodity cycles.
