Constellation Energy Corporation (Nasdaq: CEG) today reported its financial results for the fourth quarter and full year 2025.

“Constellation enters 2026 well positioned to meet the nation’s growing demand for reliable, clean electricity. This past year, we welcomed Calpine to our company – expanding our generation portfolio, strengthening our commercial platform and enhancing our ability to serve customers nationwide,” said Joe Dominguez, president and CEO of Constellation. “With the nation’s largest nuclear fleet at the core of our strategy, we’re pairing the grid’s most reliable power with flexible resources to meet accelerating demand driven by electrification and the data economy. Our long-term agreements with Microsoft, Meta and most recently CyrusOne demonstrate how we’re putting that expanded portfolio to work while maintaining reliability for customers and keeping costs stable. And none of this happens without our people, who deliver outstanding performance every day. We’re at a pivotal moment for American competitiveness, and Constellation is ready to meet it.”

“For the fourth consecutive year, Constellation delivered full-year earnings that exceeded the midpoint of our guidance range, reflecting strong commercial execution and industry-leading performance from our nuclear fleet,” said Shane Smith, executive vice president and chief financial officer. “After closing the Calpine transaction, we enter 2026 with the financial strength and flexibility to continue investing in growth and extending the life of our portfolio while delivering long-term value for shareholders. We look forward to sharing our financial outlook and strategy for 2026 and beyond with you on our March 31st conference call.”

Fourth Quarter 2025

Our GAAP Net Income (Loss) for the fourth quarter of 2025 decreased to $1.38 per share from $2.71 per share in the fourth quarter of 2024. Adjusted (non-GAAP) Operating Earnings for the fourth quarter of 2025 decreased to $2.30 per share from $2.44 per share in the fourth quarter of 2024. For the reconciliations of GAAP Net Income 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 fourth quarter of 2025 primarily reflects:

Unfavorable nuclear PTC portfolio results partially offset by favorable market and portfolio conditions

Full Year 2025

Our GAAP Net Income for 2025 decreased to $7.40 per share compared to $11.89 per share in 2024. Adjusted (non-GAAP) Operating Earnings for 2025 increased to $9.39 per share from $8.67 per share in 2024.

Recent Developments and Highlights

Calpine acquisition: On January 7, 2026, we completed our acquisition of Calpine Corporation, creating the nation's largest producer of electricity. Serving millions of customers each day, the combined organization will deliver reliable, clean power that keeps America moving forward. By uniting our zero-emission nuclear fleet with Calpine's industry-leading natural gas and geothermal generation, we are building the foundation for America's next great era of innovation – powering the data centers, advanced manufacturing facilities and critical infrastructure that are expected to play an important role in the AI age and the nation's economic leadership.

Freestone Energy Center to support new data center: Our subsidiary Calpine LLC signed a new 380-megawatt (MW) agreement with Dallas-based CyrusOne, a leading global data center developer and operator, to connect and serve a new data center adjacent to the Freestone Energy Center, in Freestone County, Texas. The agreement provides CyrusOne with access to power, grid connectivity and site infrastructure needed to support development of the new facility, while ensuring electricity continues to flow to the regional grid and ensuring reliability for all customers and communities. Calpine has also entered into an exclusive agreement to provide power, grid connectivity and site infrastructure for Phase 2, which will be an additional 380 MW. These agreements are in addition to the 400 MW agreements announced in the second half of last year between Calpine and CyrusOne for the Thad Hill Energy Center in Bosque County, Texas.

Clinton and Dresden license renewal: The Nuclear Regulatory Commission (NRC) has approved a 20-year initial license renewal for our Clinton Clean Energy Center and a 20-year subsequent license renewal for our Dresden Clean Energy Center, following a rigorous review of maintenance activities, plant equipment and safety systems at the two Illinois facilities. The approvals allow Clinton to operate through 2047 and the Dresden reactors to operate through 2049 and 2051. We are the nation’s largest operator of clean, reliable nuclear power, and we are investing more than $370 million to relicense the plants, installing state-of-the-art upgrades to increase efficiency and ensure safety and reliability for decades to come.

Crane DOE loan: In November 2025, the Department of Energy (DOE) Office of Energy Dominance Financing issued a guarantee for up to $1 billion for an unsecured loan from the Federal Financing Bank to support the financing of the restart of the Crane Clean Energy Center. The loan will mature in October 2055. Interest rates on the loan will be fixed upon each advance at a spread of 37.5 basis points above U.S. Treasuries of comparable maturity. Cash from operations will fund the remaining capital expenditures. The restart is supported by a 20-year Power Purchase Agreement (PPA) with Microsoft to purchase the output generated from the renewed plant. The restart of the plant and delivery of electricity under the PPA is subject to certain regulatory approvals, including the NRC comprehensive safety and environmental review, as well as permits from relevant state and local agencies.

Dividend Declaration: Our Board of Directors has declared a quarterly dividend of $0.4265 per share on our common stock. The dividend is payable on Friday, March 20, 2026, to shareholders of record as of 5 p.m. Eastern time on Monday, March 9, 2026.

Nuclear Operations: Our nuclear fleet, including our owned output from the Salem and South Texas Project (STP) Generating Stations, produced 45,459 gigawatt-hours (GWhs) in the fourth quarter of 2025, compared with 45,494 GWhs in the fourth quarter of 2024. Excluding Salem and STP, our nuclear plants at ownership achieved a capacity factor of 93.1% and 94.8% for the fourth quarter of 2025 and 2024, respectively, and 94.7% and 94.6% for the twelve months ended December 31, 2025 and 2024, respectively. There were 63 planned refueling outage days in the fourth quarter of 2025 and 66 in the fourth quarter of 2024. There were 30 non-refueling outage days in the fourth quarter of 2025 and three in the fourth quarter of 2024.

Natural Gas, Oil, and Renewables Operations: The dispatch match rate for our gas and pumped storage hydro fleet was 99.4% and 93.2% in the fourth quarter of 2025 and 2024, respectively, and 97.9% and 97.4% for the twelve months ended December 31, 2025 and 2024, respectively. Energy capture for the wind, solar and run-of-river hydro fleet was 97.2% and 95.7% in the fourth quarter of 2025 and 2024, respectively, and 96.6% and 96.1% for the twelve months ended December 31, 2025 and 2024, respectively.

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, which may result in an effective tax rate that differs from the marginal rate. The marginal statutory income tax rate was 25.6% and 25.5% for the three and twelve months ended December 31, 2025 and 2024, respectively. The following table provides a reconciliation between GAAP Net Income (Loss) Attributable to Common Shareholders and Adjusted (non-GAAP) Operating Earnings for the three and twelve months ended December 31, 2025 compared to the same period in 2024.

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 (Loss).

The tables above provide a reconciliation of GAAP Net Income (Loss) 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 (Loss) 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.
