Uranium Production Guidance vs Actual Output: How to Measure Delivery Risk
60-second answer: Uranium producers regularly miss their original plans, and the misses are where supply forecasts break. Measuring delivery risk takes a method, because a producer can beat its revised target while missing its original one: Cameco's 2025 output of 21.0 million pounds (its share) beat the revised "up to 20" guidance by 5%, but the year began with a larger per-mine plan that was cut in August (Cameco's results filing). The method: fix the ownership basis and unit before comparing anything, score actuals against the guided range (not the midpoint), keep the revision history, and treat withdrawn guidance as its own outcome. Our guidance tracker applies exactly these rules, with every row linked to the producer's own disclosure.
Production guidance is the supply side's forward curve, and its revision history is a measurable record of execution. Read carelessly, the same numbers can make a producer look like a chronic misser or a consistent beater. The difference is almost always in the comparison, not the pounds.
Original guidance, revised guidance and actuals
One reporting period produces up to three numbers: the plan issued before the year (original guidance), any mid-year change (revised guidance), and the reported result (actual). All three matter, because each pairing answers a different question:
- Actual vs revised measures short-horizon execution: did the company do what it most recently said?
- Actual vs original measures planning reliability: how good was the year-ahead promise?
- Revised vs original is the cut or raise itself, which for supply modeling is often the event, since the market learns about lost pounds at the revision, months before the actual prints.
A tracker that overwrites guidance on each revision destroys the second and third comparisons. Ours appends revisions instead, keeping the miss history intact.
Normalize period, unit and ownership basis first
Producer disclosures mix reporting conventions, and cross-basis comparisons produce confident nonsense. Three normalizations come before any arithmetic:
- Ownership basis. Kazatomprom reports production on both a 100% basis (everything its operations produced, including joint-venture partners' shares) and an attributable basis (its own share): 25,839 tU vs 13,519 tU for 2025. Cameco guides some figures per mine on a 100% basis and reports consolidated production as its share. A 100%-basis target must never be scored against an own-share actual; the pair must share one declared basis.
- Units. Kazakh production is stated in tU, Western producers in pounds of U₃O₈ (a tonne of uranium is about 2,600 lb of U₃O₈; our units converter handles it). Magnitudes also mix: Boss Energy guided "1.6 Mlb" and reported drummed pounds; the comparison has to normalize Klb against Mlb before dividing.
- Period. Cameco and Kazatomprom report calendar years; Paladin and Boss report June-ending fiscal years. "FY2026" and "CY2026" overlap by half.
A worked example: Cameco 2025
The 2025 sequence shows why one percentage cannot summarize a year:
- February 2025: plan of 18 million pounds (100% basis) at each of McArthur River/Key Lake and Cigar Lake.
- August 28, 2025: McArthur River/Key Lake cut to 14–15 million pounds (100% basis) on development delays in new mining areas and slower ground freezing; consolidated guidance set at up to 20 million pounds, Cameco's share.
- February 2026 actual: 21.0 million pounds (Cameco's share). On a 100% basis, Cigar Lake delivered 19.1 million pounds and McArthur River/Key Lake 15.1 million.
Scored correctly: the own-share actual of 21.0 beat the own-share ceiling of 20 by 5%. The per-mine story is mixed: Cigar Lake outperformed its plan while McArthur River finished below its original 18 and at the top of its revised range. And the original February plan was not delivered as issued. All three statements are true at once; a single "beat" or "miss" label erases two of them (source filing).
Range outcomes are not midpoint deviations
Guidance is usually a range, and a range defines the promise. An actual of 3.02 million pounds against 3.0–3.6 guidance is inside the range: the producer did what it said, even though the result sits 8% below the midpoint. Those are two separate facts, and our tracker displays them separately: an outcome badge (in range, below range, above range) plus the percentage versus the midpoint as context. Collapsing them into one number manufactures misses that never happened, or hides near-misses at the bottom of wide ranges. Ceilings need the same care: "up to 20" has no floor, so a result below 20 is indeterminate against that guidance, while a result above it is an unambiguous beat.
Withdrawn targets and ramp-up rates
Two guidance forms resist the standard scoring:
- Withdrawn guidance. Paladin withdrew its FY2025 guidance entirely in March 2025 after flooding halted Langer Heinrich; Peninsula withdrew its CY2025 guidance and later the reset CY2026 forecast as its Lance ramp-up slipped. A withdrawn target cannot be met or missed; scoring the eventual actual against it would grade the company on a promise it formally cancelled. The tracker labels these withdrawn, with the date.
- Rate targets. Ramp-up guidance often comes as a rate ("200,000 lb per month by Q2") rather than an annual quantity. A rate reached in December is not an annual volume, and annualizing a single strong month overstates the year. Rates get compared to rates, on dates.
Production is not sales, shipments or inventory
Cameco produced 21.0 million pounds (its share) in 2025 and sold 33.0 million: the difference came from purchases, inventory and long-term purchase agreements, and both figures are correct for their own question. Production measures mine execution; sales measure the marketing book; shipments can lag drummed production across period ends. Supply models want production; revenue models want sales; neither substitutes for the other, and quarterly headlines routinely swap them.
Use the tracker, inspect the sources
Our guidance tracker holds the sector's guidance-vs-actual record with the revision history intact: Kazatomprom's acid-constrained cuts and mid-range delivery, Cameco's 2024 and 2025 sequences, Paladin's FY2025 withdrawal and FY2026 above-range recovery (4.82 million pounds against a raised 4.5–4.8 range), Boss Energy's FY2026 cut and in-range landing, and Peninsula's consecutive withdrawals. Every row links the producer's own filing, and the SEC filings tracker holds the underlying documents. For what the misses mean at market level, the supply and demand guide carries the balance; guidance risk is the reason its supply lines deserve error bars.
Frequently asked questions
How often do uranium producers miss guidance? Often enough that the revision history is the interesting dataset: of the recent completed periods in our tracker, Kazatomprom cut its 2025 plan about 18% before delivering mid-range, Cameco cut and then beat its revised 2025 ceiling, Paladin withdrew FY2025 guidance entirely, and Boss landed inside a revised range after an April cut. Original plans get delivered as issued less often than headline "met guidance" labels suggest.
What is the difference between 100% basis and attributable production? 100% basis counts everything an operation produced regardless of who owns it; attributable (or own-share) counts only the reporting company's ownership slice. Kazatomprom's 2025 output was 25,839 tU on a 100% basis and 13,519 tU attributable. Comparing across bases inflates or halves results.
Can a producer beat guidance and still have missed its plan? Yes, when the beat is measured against revised guidance. Cameco's 21.0 million pounds in 2025 beat its revised up-to-20 ceiling while the original February plan had been cut in August. Always ask which guidance an outcome is being scored against.
What does withdrawn guidance mean? The company formally cancelled its target, usually amid operational disruption, and no longer stands behind any number for the period. It is a distinct outcome, worse than a cut as a signal, and an actual reported later is not a beat or miss against the cancelled target.
Why does production differ from sales? Producers sell from inventory and purchases as well as from mine output. Cameco sold 33.0 million pounds in 2025 against 21.0 million produced (its share). Supply analysis uses production; sales belong to revenue analysis.
