Constellation Energy Just Raised Guidance. Here's What's Driving It.

CEG raised its full-year adjusted operating earnings guidance by $0.50 per share to a range of $11.50–$12.50, following a 33% year-over-year jump in second-quarter adjusted operating earnings. The upward revision comes as the company integrates its Calpine acquisition, which brought 22 gigawatts of power generation capacity into the fold.

Constellation has locked in major long-term power purchase agreements with MSFT and META, positioning the company to capture surging data center energy demand. The firm now operates 55 gigawatts of total capacity, anchored by the largest nuclear fleet in the United States.

The hyperscaler deals provide revenue visibility as AI infrastructure buildouts accelerate power consumption. CEG's nuclear assets offer round-the-clock baseload generation, a critical advantage as tech companies seek reliable, low-carbon energy sources for data centers.

The Calpine integration expands Constellation's geographic footprint and generation mix, adding natural gas capacity to complement its nuclear base. The combined portfolio strengthens the company's ability to serve large, credit-worthy counterparties with multi-year commitments.
