Cameco Provides Preliminary Third Quarter Operating Update

Saskatoon, Saskatchewan, Canada, October 11, 2022

Cameco (TSX: CCO; NYSE: CCJ) today is providing preliminary operating results for its third quarter ended September 30, 2022.

On October 27, 2022, we plan to announce our 2022 third quarter results before markets open. We expect to announce deliveries in the uranium segment for the quarter ended September 30, 2022, to be between 5 million and 5.5 million pounds, in line with the pattern of deliveries for the third quarter of 2022 disclosed in our annual MD&A. In our fuel services segment, we expect to announce deliveries for the same period of between 2.1 million and 2.4 million kilograms of uranium (“kgU”).

Production in our uranium segment for the quarter ended September 30, 2022, is expected to be 2 million pounds (our share) from Cigar Lake. Production in our fuel services segment is expected to be 1.5 million kgU for the same period.

The restart activities at McArthur River and Key Lake continue to progress with first production coming from the mill expected later in the fourth quarter of 2022.

Our Inkai joint venture has continued to experience delays in shipping material via the Trans-Caspian route. Depending on when we receive the shipment of our share of Inkai’s 2022 production, our 2022 share of earnings from this equity-accounted investee and the timing of the receipt of our share of dividends from the joint venture may be impacted.

Interest by third parties in contracting with us for the supply of our uranium and fuel services remains strong. Utilities continue to be focused on ensuring they have the conversion and enrichment services they require secured under long-term contracts. As a result, we are seeing prices for conversion at historic highs and have been focused on agreeing to long-term supply terms with customers to meet their increased demand. Year-to-date, we have added to our long-term contract portfolio more than 50 million pounds in our uranium segment and more than 7 million kgU UF6 conversion in our fuel services segment.
