Cameco posts lower Q3 2026 earnings amid Key Lake maintenance outage and reduced Westinghouse equity income
Cameco (TSX: CCO; NYSE: CCJ) reported net earnings of $43 million for the third quarter of 2026 and $199 million for the first nine months of the year — both below the comparable 2025 periods. The uranium producer dropped its Q3 results on October 30, 2026, pointing to a planned extended maintenance outage at its Key Lake mill, lower equity earnings from its Westinghouse investment, and reduced sales volumes as the main drivers of the year-over-year decline.
Q3 2026 financial results at a glance
The headline number doesn’t tell the whole story. Cameco posted an adjusted net loss of $2 million for Q3 2026 and adjusted EBITDA of $267 million for the quarter. Zoom out to the first nine months, though, and the picture looks more comfortable: adjusted net earnings of $279 million and adjusted EBITDA of $1.2 billion.
The balance sheet stayed solid heading into Q4. As of September 30, 2026, Cameco held $860 million in cash and equivalents, carried $1.0 billion in total debt, and kept a $1.0 billion revolving credit facility completely undrawn. The board also declared a 2026 annual dividend of $0.24 per common share, payable December 15, 2026, to shareholders of record on November 30 — a figure reviewed each year against cash flow, financial position, and the cyclical nature of the business.
Fuel Services posted Q3 earnings before taxes of $13 million and adjusted EBITDA of $24 million — modestly below Q3 2025 figures of $17 million and $25 million.
Key Lake outage and Westinghouse comparison drove year-over-year decline
Two specific factors explain most of the gap between 2026 and 2025 results. Cameco deliberately planned a longer-than-usual maintenance shutdown at Key Lake mill, starting in Q3, to install new infrastructure and repair major existing infrastructure — projects designed to support long-term operational flexibility. That extended outage cut production volumes and pushed unit costs higher for the quarter.
A one-time item also inflated Westinghouse’s 2025 equity earnings in a way that has no 2026 equivalent. Last year, Westinghouse received an approximately US$170 million payment tied to the Dukovany nuclear power plant construction project in the Czech Republic, significantly boosting Cameco’s share of Q2 2025 revenue. Nothing comparable happened in 2026, so the year-over-year comparison looks unfavorable by design. Lower planned uranium sales delivery volumes and inflationary pressure on unit costs added to the drag.
Segment-level performance: uranium, fuel services, and Westinghouse
In the uranium segment, Q3 2026 earnings before taxes came in at $175 million, slightly ahead of $172 million in Q3 2025. Adjusted EBITDA fell to $179 million from $220 million, reflecting lower planned sales delivery volumes and higher costs. For the first nine months, uranium earnings before taxes reached $703 million and adjusted EBITDA was $855 million, compared to $681 million and $862 million in the same 2025 period.
Fuel Services posted Q3 earnings before taxes of $13 million and adjusted EBITDA of $24 million — modestly below Q3 2025 figures of $17 million and $25 million. Year-to-date, the segment earned $87 million before taxes and $120 million in adjusted EBITDA, down from $129 million and $158 million in 2025, driven by normal variations in product mix.
Westinghouse reported a net loss of $24 million (Cameco’s share) in Q3 2026, which was actually an improvement from a $32 million net loss in Q3 2025. Cameco’s share of Westinghouse’s adjusted EBITDA rose to $143 million from $124 million in the prior-year quarter — a meaningful operational gain the net loss figure alone doesn’t capture. At JV Inkai, the Kazakhstan joint venture remains on track to produce 10.4 million pounds of U3O8 (100% basis) in 2026, with Cameco’s 4.2 million pound purchase allocation currently in transit and expected at Blind River before year-end.
Outlook narrowed for 2026 production and deliveries
With better visibility into year-end timing, Cameco tightened its 2026 production guidance. The company now expects its share of uranium output to fall between 19.5 million and 20.5 million pounds of U3O8, narrowed from a prior range of 19.5 million to 21.5 million pounds.
Sales and delivery volume guidance moved similarly, to 29.5–30.5 million pounds from the previous 29–32 million pound range. The tighter band reflects improved confidence in delivery scheduling as the year wraps up. Looking further out, Cameco’s contracting portfolio covers average annual deliveries of over 28 million pounds of U3O8 per year over the next five years, weighted more heavily toward 2026 through 2028. CEO Tim Gitzel was direct: Cameco won’t accelerate production or deploy capital simply in response to short-term price movements or market enthusiasm.
Westinghouse activity and executive succession round out the quarter
Westinghouse had an active quarter on the project development front. In October, it issued conditional purchase orders with four Polish suppliers for the Lubiatowo-Kopalino AP1000 project and received authorization to procure long-lead nuclear components — steps aimed at securing supply chain capacity and reducing execution risk. That same month, Westinghouse launched a US State Department-funded FEED study for an AP1000 reactor at Slovakia’s Jaslovské Bohunice site.
In September, the US and South Korea announced a non-binding framework anticipating up to US$120 billion in Korean investment to help finance up to eight new large-scale US reactors, including six Westinghouse AP1000 units.
What the quarter adds up to
Cameco’s Q3 2026 results reflect a company managing planned disruptions rather than unexpected setbacks. The Key Lake outage was deliberate, designed to extend long-term mill flexibility, and the Westinghouse earnings shortfall versus 2025 traces directly to a one-time prior-year payment with no 2026 counterpart. Underlying operational trends — rising Westinghouse adjusted EBITDA, stable uranium segment earnings, a strong balance sheet — point to a business executing broadly in line with its own expectations. On the leadership front, Leah Hipperson will step into the CFO role on January 1, 2027, with Heidi Shockey remaining as executive director, finance through March 31, 2027, before her planned retirement.
