Shares of Cameco Corporation (CCJ) jumped 5.08% in pre-market trading on Thursday, following the release of the company's impressive second-quarter 2025 financial results. The uranium producer's strong performance, driven by increased uranium sales and its Westinghouse investment, has sparked investor enthusiasm.

Cameco reported net earnings of $321 million for Q2 2025, with adjusted net earnings reaching $308 million, marking a significant improvement from the same period in 2024. The company's adjusted EBITDA hit $673 million for the quarter, while the first half of 2025 saw net earnings of $391 million and adjusted EBITDA of $1.0 billion, demonstrating substantial growth compared to the previous year.

The robust financial results were attributed to several factors, including higher equity earnings from Cameco's investment in Westinghouse and strong performance in both uranium and fuel services segments. In the uranium segment, earnings before income taxes and adjusted EBITDA rose by 46% and 43% respectively in Q2 compared to 2024, driven by increased sales volumes and improved average realized prices. Despite higher costs associated with increased sales volumes and the annual maintenance shutdown at the Key Lake mill, Cameco's strategic positioning in the nuclear energy sector continues to yield positive results, setting a strong foundation for future growth.
