Constellation Energy Q3 Earnings Top Estimates

Constellation Energy’s third-quarter earnings topped estimates, and on Nov. 9, 2026, the company raised and narrowed its full-year adjusted operating-earnings guidance, citing stronger commercial and capacity conditions as key drivers.

Quarter Results and Guidance

The company reported adjusted operating earnings of $5.06 per share for the quarter ended Sept. 30, 2026, up from $3.04 a year earlier and above the consensus estimate of $3.89, according to its Nov. 9 press release. The Form 8-K filing showed operating revenue of $9.55 billion, a 45.4% increase year over year that exceeded the $9.35 billion estimate. GAAP net income was $1.835 billion, or $5.19 per diluted share. The investor presentation listed third-quarter operating income at $2.492 billion.

For the first nine months of 2026, operating revenue reached $28.2 billion, compared with $19.5 billion in the same period in 2025. Operating income rose to $5.4 billion from $2.5 billion, and cash flow from operating activities increased to $5.0 billion from $3.4 billion.

The company raised and narrowed its full-year 2026 adjusted operating-earnings guidance to $12.50–$12.80 per share, up from the prior range of $11.50–$12.50.

Drivers and Growth Outlook

Investor materials attributed the year-over-year revenue increase to the January Calpine acquisition, favorable commercial conditions, and capacity revenue. Offsets included lower production-tax-credit revenue, higher operations and maintenance costs, increased interest expense, and factors affecting the nuclear production-tax-credit portfolio.

Nuclear generation in the third quarter totaled 46,677 gigawatt-hours, slightly above 46,477 gigawatt-hours a year earlier. Excluding the Salem and South Texas Project plants, the fleet’s capacity factor was 97.2%, compared with 96.8% previously.

On Oct. 27, 2026, Constellation and the Department of Energy announced a conditional loan agreement of up to $5 billion to support uprates at eight reactors in Illinois, Maryland, and Pennsylvania. The agreement includes a 20-year commercial package adding 890 megawatts of uprated capacity and 15 years of supply linked to a Google-related power arrangement.

The company set a longer-term target for base earnings per share growth of more than 20% from 2026 through 2029 and a rolling three-year base-EPS growth target of at least 10%. Project timing includes a 190-megawatt Calvert Cliffs expansion expected online between 2030 and 2032, the first Google-supported uprate in 2028, and a 270-megawatt Peak+ agreement starting in 2028.

The outlook excludes potential upside from additional long-term contracts, higher gas utilization, expanded commercial margins, and higher-return growth investments. Factors that could affect results include higher interest expense, lower production-tax-credit revenue, operations and maintenance costs, market conditions, project execution, and regulatory or financing developments.
