A production total or cash-cost figure alone cannot tell you which company has the stronger business—or which stock is better valued. Cameco’s 2025 results illustrate why: it produced 21.0 million pounds attributable to the company, delivered 33.0 million pounds, and ended the year with 9.7 million pounds of inventory. Those are three different measures, not interchangeable estimates of mine output.
Start by identifying what each company actually does
Uranium stocks do not all represent the same kind of exposure. One company may earn most of its money from mining; another may also buy and resell uranium, provide conversion or fuel services, or own interests in other nuclear businesses. These differences affect how revenue and earnings respond to uranium prices and customer delivery schedules.
Cameco combines uranium production with other businesses
Cameco’s business is broader than its mines. In 2025, it reported 14.0 million kgU of fuel-services production, including 11.2 million kgU of UF6. It also reported that Westinghouse net earnings increased by $276 million compared with 2024. Those activities mean Cameco should not be assessed as though every part of its results were generated by uranium mining. See the Cameco 2025 Annual Report.
Peer company names do not guarantee a like-for-like comparison
Kazatomprom reported that approximately 20% of global primary uranium production in 2025 was attributable to the company. That is a scale indicator, not a direct comparison with Cameco’s earnings mix, contract book, costs, or share valuation. For each prospective peer, establish whether its exposure comes from mining, marketing and purchases, processing, fuel services, or a combination. Kazatomprom’s 2025 full-year results provide its scale disclosure; use company filings to establish the business mix for any other stock you add.

Keep production, ownership, deliveries, and inventory separate
A company’s headline production may be stated on a 100%-project basis, on an attributable basis reflecting its ownership share, or as a blend of mined and purchased material. Read the label and reporting basis before comparing numbers.
Cameco reported 21.0 million pounds of uranium production attributable to the company in 2025, while its site-level reporting also includes production on a 100% basis. It reported 33.0 million pounds delivered and 9.7 million pounds of inventory at year-end. Because Cameco purchased uranium as well as producing it, deliveries exceeding attributable production do not mean the mines produced the difference. Production, sales or deliveries, and inventory answer different questions: operating output, customer shipments, and material held at a point in time, respectively. The figures cover the year ended December 31, 2025; Cameco published its FY2025 results on February 13, 2026. Details are in the annual report and Q4 2025 results.
For every producer, check whether a number is company-attributable or project-wide, mined or purchased, and annual or interim. Do not rank companies by delivered pounds if your question is about mine output, or by project-wide pounds if your question is how much output accrues to the listed company.

Compare sales and contract books, not just the uranium price
Production does not determine when material is sold or what price the producer realizes. Contract volumes, delivery schedules, and pricing formulas can cause reported sales and earnings to differ from current spot-market conditions.

After completing its 2025 deliveries, Cameco reported about 230 million pounds of remaining long-term uranium commitments, with an average annual delivery volume of about 28 million pounds over the following five years. These are company-reported commitments and expected average delivery volumes, not a guarantee of annual mine production or a stated realized price. Compare them with the company’s production plans, inventory, and contract pricing disclosures in the 2025 Annual Report.
Pricing formulas and delivery timing can differ by company
Kazatomprom says its sales portfolio includes spot-linked long-term contracts and some fixed-price components and ceilings. Its 1H 2025 results also caution that quarterly production and sales patterns can vary with customer delivery timing. A useful peer comparison therefore records contract volume, timing, pricing references, fixed-price elements, ceilings or floors where disclosed, and how much detail the company provides. Do not assume that two companies with similar production have the same exposure to short-term uranium prices. See Kazatomprom’s 1H 2025 results and 2026 production strategy.
Rank #3
Use cost figures only when their definitions and periods match
Cash cost and all-in sustaining cost (AISC) are not automatically standardized across issuers. Before comparing them, match the reporting period, currency, ownership basis, cost definition, treatment of royalties and taxes, and treatment of sustaining capital. Also check whether the operation is an in-situ recovery (ISR) mine or a conventional operation: different operating systems can make a single headline cost measure incomplete.
Kazatomprom reported an attributable C1 cash cost of USD 17.86 per pound and attributable AISC of USD 30.81 per pound for the six months ended June 30, 2025. These are interim figures, in U.S. dollars, on an attributable basis. They should not be set directly against a Cameco annual, site-level, or differently defined metric and presented as a clean cost ranking. The definitions and period are in Kazatomprom’s 1H 2025 results; the available disclosures do not establish an equivalent full-year peer cost table.
Low reported cost can be attractive, but it does not by itself establish durable economics. A sound comparison also asks whether output is reliable, whether sustaining or expansion capital is required, and whether taxes, royalties, input costs, or logistics could change the cost base.
Rank #4
Assess asset reliability, jurisdiction, and supply-chain exposure
A mine’s current output or unit cost is only part of its investment case. Compare capacity, reserves and resources, recovery, ramp-up plans, maintenance, disruptions, and remaining mine life using disclosures for the same assets and dates. The figures available here are not a complete, current asset-by-asset comparison for Cameco and every peer, so they do not support a ranking on those measures.
Location and operating conditions matter alongside geology. Review permitting, taxes, transport routes, key input availability, joint-venture control, currency exposure, and relevant export-policy or sanctions risks. A company’s stated capacity does not guarantee that material can be produced and delivered on schedule.
For example, Cameco described supply-chain issues including sulphuric acid delivery instability at Inkai in its 2024 annual report. It said operations resumed on January 23, 2025, after a temporary pause. Kazatomprom cited sulphuric acid costs and Kazakhstan’s mineral extraction tax as factors behind higher cash costs in its 1H 2025 results. These are dated disclosures illustrating different operating exposures; they do not establish that the Inkai issue continues or that the cited Kazakh cost factors will persist unchanged. Sources: Cameco 2024 Annual Report and Kazatomprom 1H 2025 results.
Use producer lists carefully
The U.S. Energy Information Administration’s Form EIA-858 Table 24 lists sellers to U.S. civilian reactor owners and operators for 2023–2025, including Cameco, Kazatomprom, Paladin Energy, Orano, and Energy Fuels, among others. It is useful for identifying companies in that part of the supply chain. Seller status alone does not show comparable mine production, establish how much production is attributable to a listed company, or indicate how pure-play its stock is. The table is not a global producer ranking. See the EIA Uranium Marketing Annual Report, Table 24.
A practical checklist for comparing uranium stocks
- Define the exposure. Separate earnings from mining, purchases or marketing, conversion and fuel services, and other businesses.
- Normalize the production numbers. Record the reporting period, ownership basis, and whether the figure is mined, purchased, or received from a joint venture.
- Map sales against supply. Compare delivered volumes, inventory, remaining commitments, and contract pricing terms; do not treat deliveries as mine output.
- Match cost measures. Use the same period, currency, attributable or project basis, cost definition, tax and royalty treatment, and sustaining-capital treatment.
- Test operating durability. Review asset capacity, reliability, ramp-ups, disruptions, input supply, logistics, and future capital needs.
- Check financial resilience. Compare liquidity, debt, capital commitments, and share count or dilution using current, consistently dated company disclosures.
- Only then compare valuation. Use a common market-data date and a valuation measure that reflects each company’s business mix. A miner with substantial services or other businesses may not be comparable to a concentrated producer on a single earnings multiple.
What this comparison can—and cannot—tell you
The disclosed figures show why Cameco cannot be evaluated on mine output alone and why Kazatomprom’s interim unit costs require careful matching before they are compared with another producer. They do not establish which stock is cheapest or best: no common-date share prices, enterprise values, or valuation multiples are provided here. A relative valuation conclusion requires current market data alongside the operating and contract analysis above.
