Reasons Behind the Success
A key factor driving Cameco’s performance was its investment in Westinghouse, where it holds a 49% stake. This investment produced $780 million CAD in adjusted EBITDA, reflecting a 61% increase from the previous year. Additionally, uranium prices rose by 9%, reaching $91.44 CAD per pound, contributing to a full-year net earnings of $590 million CAD, up from $172 million in 2024.
CEO Tim Gitzel emphasized the importance of nuclear energy in addressing long-term global energy challenges, highlighting a trend of growth supported by electrification and energy security priorities.
Constellation Energy’s Upcoming Earnings Report
Constellation Energy’s shares increased by 1.65% this week, climbing to $293.20. The boost comes amid discussions on direct power agreements between nuclear generators and data centers, with a notable deal involving Constellation and CyrusOne. Major financial institutions like Wells Fargo and Barclays continue to endorse the stock, maintaining buy ratings with price targets of $460.
Market Context and The Future
Utilities are increasing capital spending due to rising demand from data centers. Southern Company has raised its spending plans by 7%, while Evergy boosted its capital investments by 24% to $21.6 billion after securing contracts with major tech companies.
Despite the recent uptick, Constellation is facing challenges, down 17% year-to-date. The upcoming earnings report, expected tomorrow morning, is anticipated to reveal adjusted earnings of $2.25 per share, which could influence investor sentiment further.
