NexGen Energy: Leading Uranium Asset With Strategic Importance - Initiate at Overweight

We initiate coverage on NexGen Energy (NXE US, NXE CN) with an Overweight recommendation and Dec-27 $14 (C$19) price target, reflecting ~50% upside. The portfolio screens favorably in terms of grade (>2% U3O8), scale (>10% market) and jurisdiction (Canada). Equally important, the 100%-owned Rook I project is fully permitted, is well supported by funding providers and we see a path to a multi-decade mine life as adjacent prospects (e.g., Patterson Corridor East) are integrated into the mine plan. We model a 4.5-year construction period with first production 1Q CY31 (~6-month delay) and assume C$3.3B capex (+50% vs scope) to reflect industry-wide inflation and potential cost pressures through shaft development, which is the critical path. Steady-state EBITDA is C$2.5B (FCF ~C$1.8B). A full funding package is expected in the next 6-12 months, with our base case assuming a mix of prepayments (C$1.4bn) and equity (C$1B). Key risks are schedule/cost pressure in shaft development and the nove
