Cameco shares on the Toronto Stock Exchange closed at C$154.91 on Friday, marking a 7.1% weekly gain, as the uranium producer resumed full operations at its McArthur River mine and Key Lake mill in northern Saskatchewan. The company confirmed on May 27 that both facilities had returned to normal production following disruptions caused by flooding that damaged the Smoothstone River Bridge, a key supply route.
The restart news reassured investors that the issue was primarily logistical rather than a production setback. Cameco reiterated its 2026 consolidated production guidance of 19.5 million to 21.5 million pounds of U3O8, a uranium concentrate used as nuclear fuel feedstock. This stability in output expectations helped drive the stock higher, with shares climbing 3.4% on Thursday alone following the announcement.
Analyst Support Remains Strong
CIBC maintained an “Outperformer” rating on Cameco with a C$200 price target, while National Bank of Canada kept an “Outperform” rating and C$180 target. Both ratings reflect confidence in the company’s ability to navigate supply chain challenges and maintain production momentum.
The broader market also provided tailwinds. Canada’s S&P/TSX Composite Index rose 0.7% on Friday and posted a 2.4% gain for May, led by technology and metal-mining shares. Peer uranium stocks also firmed, with NexGen Energy rising to $11.56 and Denison Mines closing at $3.48, though their business models differ from Cameco’s integrated operations.
Financial Performance and Diversification
Cameco reported first-quarter net earnings of C$131 million earlier in May, with adjusted EBITDA of C$509 million. CEO Tim Gitzel described the results as “consistent with our annual expectations” and noted “on-track production.” Derren Nathan, head of equity research at Hargreaves Lansdown, called the quarter an “encouraging start,” citing improving uranium volumes and prices, along with contributions from Westinghouse.
Cameco’s business extends beyond mining. The company operates through uranium, fuel services, and Westinghouse segments, providing exposure to mining, conversion, and reactor services. This diversification reduces reliance on spot uranium prices and adds resilience to its earnings profile.
Risks and Outlook
Despite the positive momentum, risks remain. Cameco noted that the timing to restore the primary supply route is not yet confirmed, and spring thaw or additional precipitation could again restrict road access and delay deliveries of critical materials. Investors will be watching for any signs of renewed supply chain disruptions.
The stock’s recent rally also raises valuation concerns. Cameco’s TSX shares have gained over 23% year-to-date, leaving less room for operational disappointments, even as analyst targets remain above current levels. The coming week will likely focus on logistics updates, uranium market sentiment, and whether analyst support holds after the sharp run.
