Cameco Corporation
Combined average of Moat (AI Resilience), Growth, and Valuation scores.
Moat Score
Cameco's moat rests on the world's two largest high-grade uranium mines (McArthur River and Cigar Lake), a 49% stake in Westinghouse Electric creating the only Western vertically integrated nuclear fuel cycle, and ~230 million pounds of contracted uranium supply locking in 39 utilities globally through 2035. The June 2026 DOE conditional loan of up to $17.5B — financing long-lead items for as many as 10 AP1000 reactors — hard-wires Westinghouse into U.S. energy policy. Q2 closed the Cigar Lake ownership increase with Orano (TEPCO stake), deepening the geological moat.
Cameco has built the only vertically integrated Western nuclear fuel chain — from Athabasca Basin ore in the ground to Westinghouse reactor fuel assemblies — at a time when energy security has made Western uranium supply a matter of national policy:
- Irreplaceable High-Grade Mine Assets: McArthur River is the world's largest high-grade uranium mine at ~16.5% U3O8 grade — 100x the global average — while Cigar Lake is the world's second-largest producer. Together with Cameco's 469+ million pounds of proven reserves, these assets represent a geological moat that cannot be replicated. In July 2026 Cameco closed the purchase, with Orano, of TEPCO's Cigar Lake stake — increasing ownership of a tier-one asset rather than adding a new one. At combined licensed capacity of 30+ million pounds per year (Cameco's share), this is a permanent cost and quality advantage.
- Westinghouse: Nuclear Services Oligopoly: Cameco's 49% stake in Westinghouse Electric transforms the company from a commodity miner into a nuclear fuel cycle company with recurring service revenue. Westinghouse services approximately 50% of the world's operating nuclear reactors and is the sole or preferred supplier for AP1000 reactor builds. The June 2026 DOE conditional loan of up to $17.5B finances long-lead items for as many as 10 U.S. AP1000s. Q2 2026 Westinghouse adj. EBITDA (Cameco share) was $163M versus $352M a year ago — the drop is the 2025 Dukovany milestone (≈US$170M) rolling off, not a demand hole.
- Long-Term Contract Structure: Commodity Cycle Insurance: Cameco's ~230 million pounds of committed uranium supply contracts — spanning 39 utilities in 16 countries and delivering ~28 million pounds per year through 2030 — feature market-linked floor/ceiling pricing that captures upside when uranium appreciates while protecting against downside. Q2 realized US$67.79/lb (+18% YoY) as older contracts roll into market-related pricing. The March 2026 India deal (9 years, 22 million pounds, ~$2.6B) extends committed revenue to 2035.
Moat Verdict
Cameco is a net beneficiary of AI adoption through the data center nuclear power demand tailwind — AI-driven electricity demand is accelerating utility investment in nuclear capacity, directly expanding demand for Cameco's uranium and Westinghouse's reactor services. The company's core moats (mine geology, regulatory approvals, long-term contract relationships) are physical and regulatory advantages entirely immune to AI-driven disruption. Of those, the high-grade orebodies and the licence stack rate strong; the contract book and the geological dataset are real but intact, because utilities diversify suppliers and the data's value is the orebody itself. Q2 2026 was a comparison-period print, not a thesis change.

Open a moat to read its note.
Cameco is a uranium mining and nuclear services company; there is no user-trained interface creating switching costs; this moat category does not apply to its business model.
Not a software business-logic moat. The deep-mining engineering that previously scored here is what makes Cameco's high-grade orebodies producible at low cost, and is now rated under scaleEconomics.
Cameco does not control access to any unique public data source; this moat category does not apply to a mining and nuclear services business.
Uranium mine engineers, radiation safety specialists, nuclear fuel cycle scientists, and NRC-qualified reactor technicians are scarce disciplines; Westinghouse's 9,000 engineers servicing 50% of the world's reactors represent a talent moat that takes decades to build, though broader competition for nuclear talent from utility operators and SMR developers creates retention pressure.
Cameco's mine-to-fuel-assembly integration (Athabasca Basin mines → Key Lake mill → Port Hope conversion → Westinghouse fuel fabrication) provides an end-to-end nuclear fuel supply offering that utilities increasingly value for energy security — though technically sophisticated buyers can source each component separately, energy security concerns make bundled Western supply the preferred option.
30+ years of Athabasca geological and mine-performance data is valuable for exploration and operations, but it is data about Cameco's own orebodies — its value is the orebody, rated under scaleEconomics — not a dataset rivals need or that compounds with customers. Re-rated from strong to intact.
Uranium mining requires CNSC licenses (Canada) that take 10-15 years to obtain for a new mine; Westinghouse holds NRC design certification for the AP1000 (only reactor with this U.S. certification); uranium is a controlled nuclear substance requiring government-to-government export agreements — the regulatory stack across mining, conversion, and reactor services creates durable, multi-decade barriers to entry and customer switching.
No meaningful network effects exist in uranium mining or nuclear services; uranium is a commodity and reactor servicing is a bilateral relationship — the value of Cameco's offering does not increase as more utilities use it; the sole network-adjacent dynamic is Westinghouse's installed base knowledge, which improves with each additional reactor serviced.
Multi-year supply contracts (230M lbs committed) make Cameco a default Western supplier, but utilities deliberately diversify across Cameco, Kazatomprom, Orano and others and re-contract on term cycles; long-term contracting is how the uranium market works, not a payment-layer lock. Re-rated from strong to intact.
Cameco is not a system of record for any information function; this moat category does not apply to a mining and nuclear services business.
McArthur River and Cigar Lake are the world's highest-grade uranium orebodies, with reserve grades around 7% and 15% U3O8 respectively against a world average well under 1%. Grade plus the freeze-wall and ground-control engineering to mine them at depth puts Cameco low on the cost curve with tier-one Western supply.

Q2 closed the Cigar Lake ownership increase with Orano (TEPCO stake), deepening the geological moat.
Growth Score
Q2 2026 net earnings $25M and adj. EBITDA $391M were down YoY because 2025 included a ~US$170M Dukovany contribution at Westinghouse — not because the uranium franchise weakened. Realized uranium rose to US$67.79/lb (+18% YoY); 2026 consolidated revenue and realized-price guidance were raised (C$3.32–3.57B; C$91–96/lb) while production of 19.5–21.5M lb (share) was held. Cigar Lake ownership increased. The DOE $17.5B AP1000 loan remains the multi-year Westinghouse ramp on top of contract repricing.
Valuation Score
Re-marked at the $88.07 close on September 25, 2026 (the last IM25 mark before the rebalance): 82 on the unchanged $70 / $130 / $200 ladder, from 78 at the $98 reference the text below was written at. Only the price moved; the ladder and the thesis are not re-underwritten here. At ~$98 — little changed from the July review as uranium spot cooled and the Dukovany comp hit the P&L — CCJ still trades ~25% below the $130 base and 47% of the way from the $70 bear toward base. Q2 raised 2026 revenue and realized-price guidance even as reported earnings fell; the DOE $17.5B AP1000 loan is unchanged. Long-term uranium price trajectory and Westinghouse execution remain the key levers.

Growth Analysis
Growth Drivers
Key Risk
Uranium spot reverses if Kazakh/Russian export restrictions resolve and 10-15M lbs/yr re-enter spot market over 2026-2027 — could compress realized prices toward contract floors and de-rate the equity.
Score Derivation
80.7 base + 4.0 trajectory + 4 margin − 10 risk = 79
Base 81 (14–18% CAGR midpoint 16%) + 4 (all three drivers accelerating) + 4 expanding margins − 10 high commodity-cycle risk = 79. The Dukovany roll-off is a comparison, not a trend; it is not charged in severity.

| 2026 revenue guide | C$3.32–3.57B |
| Net cash | ~C$0.1B |
| Price / FCF | high / lumpy |
On headline multiples CCJ looks expensive — the price embeds nuclear-renaissance option value rather than near-term earnings. GAAP EPS is distorted by Westinghouse purchase-accounting amortization and by the Dukovany 2025 spike rolling off. The multiple only rationalizes if uranium long-term prices hold and the AP1000 pipeline converts — a scarcity/optionality asset, not a P/E-anchored compounder.
Approximate figures as of August 19, 2026.
Where We Are vs Targets
Loading live price…
Uranium spot collapses back toward $50-55/lb as Kazakh and Russian supply resolves geopolitical constraints, AI data center power growth disappoints, and Westinghouse faces reactor construction delays — ROIC fails to recover above WACC.
- Kazakhstan and Russia resolve export restrictions, flooding the spot market with 10-15 million additional pounds per year; uranium spot falls to $50-55/lb, breaching Cameco's contract floor mechanisms on newer agreements and compressing realized prices toward production cost
- AI data center electricity demand growth proves slower than projected due to efficiency improvements; nuclear PPAs from hyperscalers are deferred; the nuclear renaissance narrative loses momentum and uranium-related equities de-rate sharply across the sector
- Westinghouse encounters cost overruns on the Dukovany project and AP1000 construction delays in Poland and Bulgaria; 2027-2028 EBITDA contribution falls to $400M (Cameco's share) vs. consensus $750M, and ROIC remains below WACC — impairing the strategic rationale for the $8.2B acquisition
Uranium long-term prices stabilize at $85-95/lb, Westinghouse delivers 6-10% EBITDA CAGR off a post-Dukovany base, the India deal commences delivery in 2027, and Cameco's contract book rolls forward — adj. EPS reaches $1.60-1.80 USD by FY2027.
- Uranium long-term price holds at $85-95/lb through 2026-2027, with Cameco's 28M lb/year delivery commitment repricing as below-market legacy agreements expire — Q2's US$67.79/lb realized is the path, not the peak
- Westinghouse converts the June 2026 DOE $17.5B conditional loan into firm long-lead orders and secures 3-5 new AP1000 reactor contracts in Europe and Southeast Asia; Cameco's 49% EBITDA share grows toward $800M+ by FY2027
- India uranium deliveries commence in 2027 (22M lbs across 9 years at market-related prices); additional government-to-government contracts follow from Japan, South Korea, and Eastern Europe
Uranium spot surges past $120/lb as reactor restarts and AI-driven demand outpace supply growth, Westinghouse AP1000 orders accelerate under the $80B U.S. Government mandate, and SMR optionality begins to be priced into the stock.
- Uranium spot exceeds $120/lb by late 2026 as global reactor capacity additions outpace mine restarts; Cameco's realized price hits $105-115/lb on market-related contracts; uranium segment FCF more than doubles
- The DOE $17.5B loan de-risks financing for 10 U.S. AP1000 reactors and Westinghouse receives binding construction contracts for 10+ reactors globally; Cameco's 49% EBITDA share exceeds $1B by FY2027-2028
- SMR technology matures: Westinghouse eVinci and adjacent reactor programs receive first commercial orders; the nuclear fuel cycle extends into SMR markets where Cameco's vertically integrated supply chain is the natural vendor
