The facts
GAAP net income attributable to common shareholders was $1.835 billion, or $5.19 per diluted share, for the quarter ended 30 September 2026, compared with $930 million, or $2.97 per share, a year earlier. [1]
Adjusted non-GAAP operating earnings were $1.792 billion, or $5.06 per share, compared with $952 million, or $3.04 per share, in the third quarter of 2025. The measure is not standardized and is not a substitute for GAAP results. [1]
Constellation raised the midpoint and narrowed its full-year 2026 adjusted operating earnings guidance to $12.50–$12.80 per share; the company said this was the second midpoint increase this year. [1]
The company said third-quarter adjusted operating earnings primarily reflected favorable market and portfolio conditions and the addition of Calpine. [1]
AP reported that Constellation’s quarterly profit and revenue topped analysts’ expectations; its market report recorded a 6.3% share-price increase at 10:30 a.m. Eastern time, an intraday snapshot rather than a closing price. [2]
Constellation agreed to acquire Rhode Island State Energy Center, a 609-megawatt natural-gas plant, from Shell for $715 million subject to customary price adjustments and regulatory approval. [1]
Relevant context
Constellation said the Calpine addition expanded its generation fleet in January 2026, so the year-on-year comparison reflects a larger business as well as market conditions. [1]
Still unconfirmed
- The $12.50–$12.80 adjusted operating-earnings range is management guidance; actual full-year results remain unknown.
- The company release does not quantify the separate contributions of market conditions and the Calpine addition to the year-on-year earnings increase.
