Constellation Energy Stock Rises 10.5% on Day of Third Quarter Results, With Heavier Volume

1What the company reported

On November 9, 2026, Constellation Energy reported third quarter adjusted operating earnings of $5.06 per share, compared with $3.04 a year earlier. Per share means the profit divided across each share the company has, and adjusted operating earnings is the company's own profit measure that leaves out some items. The company filed its results release with the U.S. Securities and Exchange Commission (SEC) at 6:53 a.m. ET, before the market opened.

• Sales: Operating revenues were $9,550 million for the quarter ended September 30, 2026, against $6,570 million a year earlier.
• Net profit: Net income attributable to common shareholders, measured under the standard U.S. accounting rules known as GAAP, was $1,835 million, or $5.19 per share. A year earlier it was $930 million, or $2.97 per share.
• Adjusted operating earnings: These totaled $1,792 million, against $952 million a year earlier. The release says the quarter mainly reflects favorable market and portfolio conditions and the addition of Calpine, a company Constellation acquired in January 2026.
• Items set aside: Two items sit between net profit and the adjusted figure. The release takes out a $127 million after tax gain from changes in the value of price protection contracts and similar holdings, against a $94 million loss added back a year earlier. It adds back $73 million of Calpine merger and integration costs, against $28 million a year earlier.
• Guidance: Guidance is the range a company gives for its own results in a later period. Constellation raised the midpoint (the middle of the range) and narrowed its full-year adjusted operating earnings range to $12.50 to $12.80 per share, and said this was the second time this year it raised the midpoint.
• Deals and agreements: The release says the company agreed to buy the Rhode Island State Energy Center for $715 million, subject to regulatory approvals. It also signed a conditional loan commitment with the U.S. Department of Energy for up to $5 billion to support work at nuclear plants, and lists long term agreements with Amazon and Google.
