Cameco's Bet on Westinghouse Pays Off: Can It Keep Delivering?

Cameco Corporation (CCJ) reported a robust Q2 2025, with net earnings surging 792% to CAD 321 million, largely attributable to significantly improved equity earnings from its 49% investment in Westinghouse Electric Company. Cameco's share of Westinghouse's adjusted EBITDA rose to CAD 352 million from CAD 121 million year-over-year, primarily due to Westinghouse's participation in the Dukovany nuclear reactor construction project. This strong performance led Cameco to raise its 2025 guidance for Westinghouse adjusted EBITDA share to $525-$580 million, signaling continued positive contributions from its nuclear sector investment.

Analysis

Cameco Corporation's (CCJ) strategic acquisition of a 49% stake in Westinghouse is yielding substantial returns, as evidenced by a 792% year-over-year surge in Q2 2025 net earnings to CAD 321 million. The primary driver was Westinghouse's involvement in the Dukovany nuclear power plant project, which contributed to a sharp reversal in Cameco's share of earnings from a CAD 47 million loss to a CAD 126 million gain. This performance prompted a significant upgrade to full-year 2025 guidance, with the company's expected share of Westinghouse's adjusted EBITDA now projected at $525-$580 million, up from a prior $355-$405 million. While the company projects a 6-10% compound annual growth rate in its share of adjusted EBITDA over the next five years, this forecast notably excludes the one-time $170 million revenue boost from the Dukovany project. The market has rewarded this performance, with CCJ's stock gaining 45.2% year-to-date, but this has created a stretched valuation, with its forward price-to-sales ratio at 12.45 versus the industry average of 1.24. Conflicting analyst sentiment, where 2025 earnings estimates have risen but 2026 estimates have declined, suggests potential concerns about the sustainability of this growth trajectory beyond the initial acquisition impact.

Key Decisions for Investors

• Acknowledge the strong near-term outlook driven by the Westinghouse acquisition's immediate and significant contribution to earnings, which has materially improved the company's 2025 guidance.
• Exercise caution regarding the stock's elevated valuation, as its 45.2% year-to-date appreciation and a forward price-to-sales ratio of 12.45 suggest that high expectations are already priced in.
• Monitor the sustainability of growth beyond 2025, paying particular attention to the decline in 2026 earnings estimates and the company's ability to deliver on its long-term EBITDA CAGR, which excludes the recent one-time project boost.
