On May 10, 2026, Cameco reported that flooding in northern Saskatchewan has disrupted road access to its McArthur River and Key Lake operations, following the collapse of the Smoothstone River Bridge on its primary supply route. While the company’s sites are not directly affected by flood waters, it has halted production at the Key Lake mill and reduced activity at the McArthur River mine until normal delivery of critical operating materials can resume. Cigar Lake mine continues to operate and Cameco’s consolidated annual production plan remains unchanged for now, but the company warned that prolonged road restrictions could affect its 2026 output from the McArthur River/Key Lake operation. Management is working with the Saskatchewan Ministry of Highways and site teams to manage logistics, underscoring both the vulnerability of uranium supply chains to infrastructure disruptions and Cameco’s efforts to limit operational and production impacts. The most recent analyst rating on (TSE:CCO) stock is a Buy with a C$185.00 price target. To see the full list of analyst forecasts on Cameco stock, see the TSE:CCO Stock Forecast page. Spark’s Take on CCO Stock According to Spark, TipRanks’ AI Analyst, CCO is a Outperform. The score is driven by strong financial performance (improving profitability, healthy cash generation, and a conservatively levered balance sheet) and a constructive earnings-call outlook with sizable contracted visibility and strategic positioning. The main offsets are expensive valuation (very high P/E with a low yield) and only mixed near-term technical momentum. To see Spark’s full report on CCO stock, click here.
