Filed August 6, 2026For Securities:CEG

Summary

Constellation Energy Corporation (CEG) reported strong financial results for the six months ended June 30, 2026, driven significantly by the strategic acquisition of Calpine Corporation on January 7, 2026. This acquisition, valued at approximately $21.8 billion, has substantially increased CEG's operational scale and market diversification, creating the nation's leading competitive retail electric supplier and a dominant force in clean energy generation. The company saw a significant increase in operating revenues, up 44.5% year-over-year to $18.6 billion, and a substantial rise in Net Income Attributable to Common Shareholders to $2.1 billion, an increase of 118% from the prior year's $957 million. Operationally, CEG's fleet now boasts 55 gigawatts of capacity across a diverse range of generation assets. The integration of Calpine's primarily natural gas, geothermal, battery storage, and solar assets has bolstered its position in a transitioning energy market. Despite challenges such as increased integration costs and impacts from nuclear outages, the company is actively managing its portfolio, including planned divestitures of certain Calpine assets to satisfy regulatory commitments. With a robust liquidity position and strong access to capital markets, CEG appears well-positioned to execute its strategy, invest in new technologies, and continue to drive the transition to a sustainable energy future.
