The price everyone quotes is not the price anyone earns

Cameco, the Saskatoon miner that also owns 49% of the reactor builder Westinghouse, sold its uranium last quarter at an average of US$67.79 a pound. The published spot price at the end of July was $86.36, and the price utilities pay under new long-term contracts has sat at $94 since June, the highest in 18 years. Cameco's realized price was up 18% from a year earlier and still 28% below that contract number, because deliveries come off a book signed when uranium was cheap.

That gap is the story of the whole nuclear fuel chain right now. The headline prices are at decade highs; the profit-and-loss statements are not. Over the past month shares in the fuel names rose together — Cameco 11.5%, the enricher Centrus 14.3%, the developers NexGen 21.5% and Uranium Energy Corp 26.8% — while the metal did nothing at all. Strip each name's two best sessions, clustered on a handful of shared news dates in late July and early August, and the month's gain becomes a loss. This was an event, not a re-rating.

What actually re-contracted

The events were real. Centrus, a Bethesda, Maryland company that sells separative work units — the measure of enrichment effort, or SWU — and no mined ore, disclosed a backlog of $4.5bn extending through 2040, against $2.3bn of commercial backlog three months earlier. Of that, $2.4bn of enrichment work is now under definitive agreements rather than contingent ones. It signed a firm high-assay low-enriched uranium off-take with the reactor developer X-energy and a letter of intent with Oklo to fuel up to five units from 2029, both carrying prepayments. Separately, the Department of Energy conditionally committed $17.5bn of loans on 23 June for long-lead equipment for up to ten Westinghouse AP1000 reactors, and Cameco disclosed that Westinghouse had confidentially filed for an initial public offering.

The mechanism underneath is a deadline. US reactor operators bought about 3.28 million SWU of Russian enrichment in 2025, nearly 26% of their purchases, and the waiver authority that permits it expires no later than January 2028. Urenco is adding roughly 700,000 SWU a year in New Mexico by early 2027, only a partial replacement. That shortfall is why enrichment quotes are elevated — SWU prices rose about 11% last year to $108.70 a unit.

Two income statements going the wrong way

Centrus is not capturing it yet. Enrichment-segment revenue rose 22% to $153.4m, but volumes fell 23% and realized SWU pricing rose 3% while unit costs rose 13%. Gross margin compressed to 28.3% from 34.9%, and operating income fell 69% to $10.4m. Consensus has 2026 earnings per share at $2.50, down 44% from last year. Management itself says utilities remain in wait-and-see mode until it demonstrates centrifuge installation. The balance sheet is improving — $1.9bn of cash, commercial Piketon production pulled forward to 2029 — while the earnings line deteriorates.

Cameco's quarter was worse on the surface and better underneath. Revenue of $814.1m fell 7.2%, gross margin dropped to 21.1% from 29.3%, and net income fell 92% to $25.2m, largely because its share of Westinghouse EBITDA halved to $163m against a prior year containing a one-off payment on the Czech Dukovany project. Production guidance of 19.5–21.5 million pounds held through weather disruptions at Key Lake and McArthur River and a Cigar Lake suspension after quarter-end. Its fuel-services realized price rose 13% to C$41.67 per kilogram of uranium. New contracts now carry floors in the high-$70s and ceilings near $160.

The valuation is the uncomfortable part. Cameco has fallen 17.9% in six months and become more expensive doing it: price per dollar of trailing gross profit has gone from roughly 33x a year ago to about 45x, because gross profit fell faster than the shares. Forward earnings multiple is 64.6x, up from roughly 56x in May, resting on a projected jump to $2.64 of 2027 earnings per share from $1.54 this year.

The controls

NexGen, a pre-revenue developer whose Rook I project sits in Saskatchewan's Athabasca Basin, trades at 5.27x book on a $7.02bn market value with first pounds around 2030 and financing for a C$2.2bn build not yet closed. It has 11.3 million pounds contracted, all spot-indexed, and deliberately leaves 96% of reserves uncommitted — the mirror image of Cameco's floors-and-ceilings book. Uranium Energy Corp, a Texas-based in-situ recovery producer, is guided to fiscal 2026 revenue of $26.9m, down 59%, with an $85.5m loss. Their outsized monthly gains are leverage to a metal that did not move.

One name went the other way: BWX Technologies, which builds naval reactors, fell 10.2% over the same month. Whatever lifted the fuel names, it was not indiscriminate enthusiasm for nuclear.

The setup

Where it stands — Backlogs and policy are re-contracting the Western fuel chain; realized prices and margins at both revenue-generating companies are still falling. Would confirm — Cameco's realized uranium price closing on spot in coming quarters, or Centrus posting SWU pricing gains above 10%. Would invalidate — Centrus funding Piketon through further equity sales without new priced volume, or Cameco cutting its 19.5–21.5m lb guidance. Watch next — Westinghouse's public IPO filing, and the January 2028 expiry of Russian enrichment import waivers. Valuation — Cameco 168.1x trailing and 64.6x forward earnings versus about 56x forward in May; Centrus 71.6x trailing against 72.0x forward.
