Baltimore (Aug 7, 2025) — Constellation Energy Corporation (Nasdaq: CEG) today reported its financial results for the second quarter of 2025.

“With increasing demand for electricity to power American families and businesses, AI, electric vehicles and industrial growth, we’re doing our part to ensure reliability and affordability,” said Joe Dominguez, president and CEO of Constellation. “We are adding megawatts to the grid through extending the lives of our existing fleet, expediting the Crane Clean Energy Center restart, expanding nuclear plant capacity through uprates, and launching a new, AI-powered demand response tool that helps businesses reduce energy use during periods of peak demand. These efforts reduce costs for everyone while strengthening grid reliability and reflect the kind of leadership our customers, our communities and our economy need right now.”

“Backed by continued strong performance from our Generation and Commercial businesses, Constellation delivered adjusted operating earnings of $1.91 per share this quarter, up from $1.68 per share in Q2 last year,” said Dan Eggers, chief financial officer, Constellation. “We’re reaffirming our full-year adjusted operating earnings guidance range of $8.90-$9.60 per share. Following recent approval from FERC, our transaction with Calpine remains on track to close by year-end as we look to combine two leading generation fleets and two exceptional teams to enhance our ability to serve our customers and communities coast-to-coast.”

Second Quarter 2025

Our GAAP Net Income for the second quarter of 2025 increased to $2.67 per share from $2.58 per share in the second quarter of 2024. Adjusted (non-GAAP) Operating Earnings for the second quarter of 2025 increased to $1.91 per share from $1.68 per share in the second quarter of 2024. For the reconciliations of GAAP Net Income (Loss) to Adjusted (non-GAAP) Operating Earnings, refer to the GAAP/Adjusted (non-GAAP) Operating Earnings Reconciliation section below.

Adjusted (non-GAAP) Operating Earnings in the second quarter of 2025 primarily reflects:

Higher IL banked ZEC revenues and favorable market and portfolio conditions, partially offset by lower nuclear PTCs due to higher anticipated gross receipts for the year

Recent Developments and Second Quarter Highlights

20-Year Deal with Meta for clean, reliable nuclear energy: We have signed a 20-year Power Purchase Agreement with Meta for the full output of the Clinton Clean Energy Center to support their clean energy goals and operations. The agreement, beginning in June of 2027, supports the relicensing and continued operations of the Clinton nuclear facility for another two decades and will allow us to expand Clinton’s clean energy output by 30 megawatts through plant uprates. The Clinton Clean Energy Center will continue to flow power onto the local grid, providing grid reliability and low-cost power to the region for decades to come.
Legislative support for nuclear energy: Bipartisan support for nuclear energy continues at both the federal and state levels. Passage of the One Big Beautiful Bill Act preserves and expands the nuclear provisions enacted in the Inflation Reduction Act. These are the only tax credits that have received overwhelming support from both the Republican and Democratic congressional delegations. Federal initiatives are also underway to expand the existing fleet with fast-track licensing, increase domestic conversion and enrichment of nuclear fuel, and accelerate deployment of new reactors, all while maintaining the NRC’s track record of being a responsible regulator to what is considered the safest nuclear fleet in the world. At the State level, just last week policymakers in New York called for extension of the ZEC program to ensure that the existing nuclear fleet continues to operate while NY also pursues 1 GW of new nuclear generation in the state. In Maryland and Texas, policymakers are proceeding with implementation to procure and provide financial support for new nuclear reactors in those states.
Calpine Acquisition: We received regulatory approval from the New York State Public Service Commission, the Public Utility Commission of Texas, and the Federal Energy Regulatory Commission for our acquisition of Calpine. We continue to expect this transaction to close in the 4th quarter of this year.
Crane Clean Energy Center will return to service in 2027: Exceptional project execution will allow the Crane Clean Energy Center to return to service in 2027, ahead of our original schedule. The project was selected by PJM for expedited grid connection as part of its Reliability Resource Initiative and we are ahead of schedule for other long lead time items. Restarting Crane’s Unit 1 reactor will bring new clean, firm, reliable energy to the grid at a time when it is needed to support growing demand.
Delivering on Our Capital Allocation Promises: In the second quarter we continued our share repurchase program, entering into an Accelerated Share Repurchase agreement with a financial institution to initiate the repurchase of approximately $400 million of our common stock. In addition we continued to deliver on our commitment to increase dividends by 10% in 2025.
2025 Great Place to Work Certification: For the third year in a row we were Certified™ by Great Place To Work®. The designation is based on how our employees rate their experience working at Constellation. In a survey of about 5,000 of our employees, 86% of those who responded said it is a great place to work – about 29 points higher than the average U.S. company. Great Place To Work® is acknowledged worldwide as a global benchmark for workplace culture, employee experience and the leadership behaviors proven to deliver strong market performance, employee retention and increased innovation.
Nuclear Operations: Our nuclear fleet, including our owned output from the Salem and South Texas Project (STP) Generating Stations, produced 45,170 gigawatt-hours (GWhs) in the second quarter of 2025, compared with 45,314 GWhs in the second quarter of 2024. Excluding Salem and STP, our nuclear plants at ownership achieved a 94.8% capacity factor for the second quarter of 2025, compared with 95.4% for the second quarter of 2024. There were 41 planned refueling outage days in the second quarter of 2025 and 49 in the second quarter of 2024 for sites we operate. There were 22 non-refueling outage days in the second quarter of 2025 and three in the second quarter of 2024 for sites we operate.
Natural Gas, Oil, and Renewables Operations: The dispatch match rate for our gas and pumped storage fleet was 98.3% in the second quarter of 2025, compared with 98.0% in the second quarter of 2024. Renewable energy capture for our wind, solar and run-of-river hydro fleet was 96.1% in the second quarter of 2025, compared with 96.6% in the second quarter of 2024.

GAAP/Adjusted (non-GAAP) Operating Earnings Reconciliation

The table below provides a reconciliation of GAAP Net Income to Adjusted (non-GAAP) Operating Earnings. Adjusted (non-GAAP) Operating Earnings is not a standardized financial measure and may not be comparable to other companies’ presentations of similarly titled measures.

Unless otherwise noted, the income tax impact of each reconciling adjustment between GAAP Net Income (Loss) Attributable to Common Shareholders and Adjusted (non-GAAP) Operating Earnings is based on the marginal statutory federal and state income tax rates, taking into account whether the income or expense item is taxable or deductible, respectively, in whole or in part. For all adjustments except the NDT fund investment returns, which are included in decommissioning-related activities, the marginal statutory income tax rate was 25.5% and 25.1% for the three months ended June 30, 2025 and 2024, respectively. Under IRS regulations, NDT fund investment returns are taxed at different rates for investments if they are in qualified or non-qualified funds. The effective tax rates for the unrealized and realized gains and losses related to NDT funds were 54.6% and 66.9% for the three months ended June 30, 2025 and 2024, respectively.

Non-GAAP Financial Measures

We utilize Adjusted (non-GAAP) Operating Earnings (and/or its per share equivalent) in our internal analysis, and in communications with investors and analysts, as a consistent measure for comparing our financial performance and discussing the factors and trends affecting our business. The presentation of Adjusted (non-GAAP) Operating Earnings is intended to complement and should not be considered an alternative to, nor more useful than, the presentation of GAAP Net Income.

The tables above provide a reconciliation of GAAP Net Income to Adjusted (non-GAAP) Operating Earnings. Adjusted (non-GAAP) Operating Earnings is not a standardized financial measure and may not be comparable to other companies’ presentations of similarly titled measures.

Due to the forward-looking nature of our Adjusted (non-GAAP) Operating Earnings guidance, we are unable to reconcile this non-GAAP financial measure to GAAP Net Income given the inherent uncertainty required in projecting gains and losses associated with the various fair value adjustments required by GAAP. These adjustments include future changes in fair value impacting the derivative instruments utilized in our current business operations, as well as the debt and equity securities held within our nuclear decommissioning trusts, which may have a material impact on our future GAAP results.
