Cameco Corporation reported an operational update for its northern Saskatchewan sites following regional flooding that has damaged transportation routes. Flooding caused the collapse of the Smoothstone River Bridge on the primary supply route to the McArthur River mine and Key Lake mill, and restrictions exist on an alternative road.
As a result, Cameco has temporarily halted production activities at the Key Lake mill and reduced activity at the McArthur River mine until normal deliveries of critical operating materials can resume, with the timing currently unknown. The Cigar Lake mine continues to operate, and the company’s consolidated annual production plan remains unchanged, although Cameco notes a risk that its 2026 production outlook for the McArthur River/Key Lake operation could be affected depending on the duration of road restrictions and delivery capabilities.
Cameco Corporation reported the results of its May 7, 2026 annual meeting.

Adjusted net earnings more than doubled to $203 million, and adjusted EBITDA climbed 44% to $509 million, reflecting higher uranium sales volumes, improved realized prices and higher equity earnings from JV Inkai and Westinghouse. Uranium production grew modestly, and annual production and financial guidance for 2026 remain unchanged, with management emphasizing strong long-term demand for nuclear energy.

Cameco Corporation has signed a major long-term uranium supply agreement with India’s Department of Atomic Energy. The contract covers nearly 22 million pounds of uranium ore concentrate (U3O8) over nine years, with an estimated total value of about $2.6 billion based on current uranium prices and exchange rates.
Deliveries are expected to run from 2027 through 2035, supporting fuel needs for India’s existing 24 nuclear reactors and its plan to expand capacity toward 100 GW by 2047. Cameco notes that these volumes were already included in its previously disclosed long-term contracting totals and five-year uranium price sensitivity analysis.
Cameco Corporation reported much stronger results for 2025, driven by all three segments: uranium, fuel services, and its 49% stake in Westinghouse. Revenue rose to $3.48 billion from $3.14 billion, while gross profit increased to $970 million from $783 million.
Net earnings attributable to equity holders jumped to $590 million from $172 million, and adjusted net earnings climbed to $627 million from $292 million. Adjusted EBITDA grew to $1.93 billion from $1.53 billion, supported by higher realized uranium and fuel services prices and stronger Westinghouse performance.
Cash provided by operations increased significantly to $1.41 billion from $905 million, leaving Cameco with $1.11 billion in cash and cash equivalents and $99.6 million in short-term investments at year-end. The company emphasizes a disciplined supply strategy, about 230 million pounds of uranium under long‑term contracts, and continued value-accretive contributions from Westinghouse, including a US$171.5 million cash distribution in 2025.
