- Cameco’s Toronto-listed shares closed Friday at C$154.91, up about 7.1% for the week.
- The stock’s late-week move followed the restart of McArthur River/Key Lake and unchanged 2026 production guidance.
- The week ahead turns on logistics risk, uranium sentiment and whether analyst support holds after a sharp run.
Cameco shares head into the new week with fresh momentum after the uranium producer restarted full production at its McArthur River mine and Key Lake mill in northern Saskatchewan and kept its 2026 output outlook intact.
With markets closed for the weekend, the story is last week’s repair trade. Cameco’s TSX shares ended Friday at C$154.91, up from C$144.63 a week earlier, while its NYSE line closed at $112.70, up from $104.75 on May 22, company market data showed.
The move mattered because the disruption had hit one of Cameco’s key Canadian uranium hubs. Cameco said on May 27 that Key Lake and McArthur River had returned to full production after flooding damaged the Smoothstone River Bridge, part of the primary route used to move supplies, and forced the company to rely on a secondary road.
Cameco said its 2026 consolidated production outlook stayed at 19.5 million to 21.5 million pounds of U3O8, a uranium concentrate used as nuclear fuel feedstock. That reassured investors that the flood issue was, for now, a logistics problem rather than a production reset.
The shares rose 3.4% on Thursday after the restart news, MarketScreener reported, and CIBC maintained an “Outperformer” rating with a C$200 price target on Friday. National Bank of Canada kept an “Outperform” rating and C$180 target a day earlier, according to the same feed. MarketScreener
The broader tape helped. Canada’s S&P/TSX Composite rose 0.7% on Friday and posted a 2.4% gain for May, led by technology and metal-mining shares, Reuters reported.
Peers also firmed in Friday trading, though the read-through is not clean. NexGen Energy rose to $11.56 and Denison Mines closed at $3.48, with both stocks up on the day; both are uranium names, but they do not have Cameco’s same mix of operating mines, fuel services and Westinghouse exposure.
Cameco’s own background remains important. The company reported first-quarter net earnings of C$131 million earlier in May, and adjusted EBITDA — earnings before interest, tax, depreciation and amortization, stripped of some items — of C$509 million. Chief Executive Tim Gitzel said results were “consistent with our annual expectations” and cited “on-track production.” Cameco
Derren Nathan, head of equity research at Hargreaves Lansdown, called the quarter an “encouraging start” and wrote that improving uranium volumes and prices, along with Westinghouse, drove a strong first quarter. HL
Cameco is not just a miner. Reuters’ company profile describes it as a uranium fuel provider with uranium, fuel services and Westinghouse segments, giving the stock exposure to mining, conversion and reactor services rather than only spot uranium prices.
The risk is still the road. Cameco said the timing to restore the primary supply route is not confirmed and warned that spring thawing or more precipitation could again restrict roads and delay deliveries of critical operating materials. That is the downside case for the week ahead: not weaker demand, but another supply-chain snag in northern Saskatchewan.
Investors will also watch whether the rally has run ahead of the news. Cameco’s TSX shares are up more than 23% since Jan. 1, according to MarketScreener, leaving less room for small operating disappointments, even as sell-side targets remain above Friday’s close.
