Constellation Energy Beats Q3 Estimates by Wide Margin and Raises Full-Year Guidance on Wave of Nuclear Deals

Constellation Energy reported blowout third-quarter 2026 results on November 9, posting adjusted EPS of $5.06, a 66% year-over-year jump that beat the consensus estimate of $3.85 by $1.21. Revenue rose 45% year-over-year to $9.55 billion, topping the $9.37 billion estimate, while GAAP EPS came in at $5.19, up 75% from the same period in 2025. Nuclear capacity factor held at 97.2%, up 40 basis points year-over-year. Management credited favorable market and portfolio conditions and the January acquisition of Calpine, partially offset by interest costs and nuclear production tax credit impacts.

The company raised its full-year 2026 adjusted EPS guidance to $12.50 to $12.80, up from a prior range of $11.50 to $12.50 and above the $12.15 consensus estimate, marking the second midpoint increase this year. The stock climbed roughly 7% to nearly 10% on the day, with the Dow Jones index also gaining more than 600 points. The guidance raise came despite Wall Street concerns that midterm election results could slow the data-center buildout that underpins power demand growth.

Constellation announced several major long-term commercial deals tied to AI infrastructure demand. Amazon signed a 20-year, 690 MW power purchase agreement supporting more than $3 billion of investment at Calvert Cliffs, including a 190 MW capacity expansion expected between 2030 and 2032. Google signed a 20-year PPA for approximately 890 MW backed by more than $4.3 billion in upgrades across 11 nuclear units beginning in 2028, plus a separate 15-year load-following agreement for 2,700 MW in the PJM grid. Energy firm Peak+ also signed a 20-year, 270 MW agreement commencing in 2028. Together, the company said these agreements add more than 1,000 megawatts of new emissions-free generation.

On the asset side, Constellation is acquiring the Rhode Island State Energy Center, a 609 MW natural gas facility, for $715 million, and received a conditional loan guarantee from the U.S. Department of Energy of up to $5 billion over a 30-year term to finance uprates at eight nuclear reactors. Management emphasized that the new capacity additions are structured so costs are not passed to existing customers, positioning Constellation as a central supplier as rising electricity demand becomes a binding constraint on the digital economy.
