Baltimore (Aug 6, 2026) — Constellation Energy Corporation (Nasdaq: CEG) today reported its financial results for the second quarter of 2026.

“This quarter's accomplishments reflect the momentum we're building across our business,” said Joe Dominguez, president and CEO of Constellation. “From advancing the restart of the Crane Clean Energy Center, to executing long-term agreements with our corporate customers and extending the lives of two critical New York assets, we’re strengthening the nation's energy infrastructure and helping meet growing demand for reliable power.”

Second Quarter 2026 Our GAAP Net Income for the second quarter of 2026 decreased to $1.42 per share from $2.67 per share in the second quarter of 2025. Adjusted (non-GAAP) Operating Earnings for the second quarter of 2026 increased to $2.55 per share from $1.91 per share in the second quarter of 2025. 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 2026 primarily reflects:

• The addition of Calpine and favorable market and portfolio conditions, partially offset by unfavorable nuclear outages

Recent Developments and Second Quarter Highlights

• Progress continues at Crane Clean Energy Center paving way for restart: FERC approved our waiver request to transfer CIRs from the dual fuel Eddystone Units 3 and 4 in Pennsylvania to the Crane Clean Energy Center. This decision clears a critical regulatory hurdle for the plant restart, we expect the transfer to expedite its ability to deliver reliable emissions-free power to the grid. Additionally, the NRC has approved a fuel license amendment request for the Crane Clean Energy Center — a major milestone moving us closer to restarting operations in 2027.

• Helping our customers meet their evolving energy needs: We have signed an additional 920 megawatts (MW) of long-term power purchase agreements (PPA) for clean, reliable nuclear generation with a diverse set of investment grade customers. These agreements are for 15-20 years in duration and are set to begin in 2029 through 2032. Among these PPAs, our 176 MW agreement with Walmart will enable a 30 MW capacity expansion at our Dresden Clean Energy Center in Illinois and facilitate additional investments to strengthen the local community by supporting jobs and enabling continued expansion of operations and workforce.

• Agreement to divest the Brazos Valley Energy Center: In August 2026, we entered into an agreement with LS Power to divest the Brazos Valley Energy Center (f/k/a Jack A. Fusco Energy Center), a 606 MW natural gas-fired plant in ERCOT for $860 million before closing adjustments, a key step in satisfying regulatory commitments related to our acquisition of Calpine earlier this year. This marks the last asset sale required by our regulatory commitments under the acquisition. Closing of the sale is subject to the receipt of approval by the DOJ, and other customary closing conditions. We expect the transaction to close by the end of this year.

• License renewal applications for two New York nuclear units: We have filed license renewal applications with the NRC to extend the operations of the Ginna Clean Energy Center and the Nine Mile Point Unit 1 reactor in upstate New York to 2049. If approved, the units' operating licenses would be extended 20 years, to 2049. Nine Mile Point Unit 2 is currently licensed to operate until 2046.

• Recognized for our culture: For the fourth 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, 83% of those who responded said it is a great place to work – about 26 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.

For the second year in a row we were recognized as one of the Civic 50® and as the energy sector leader by Points of Light. The Civic 50® is a well-respected standard for corporate social impact, recognizing the most community-minded companies in the U.S. for how they show up through employee volunteerism, community investment and broader social impact efforts.

We were recognized as a World’s Top Disability Inclusive Business based on our performance on the Disability Index®, the leading benchmark for disability inclusion. This recognition signifies that we’re a leading performer in disability inclusion, accessibility and workplace practices. It's also a reflection of our commitment to fostering an environment where all employees can do their best work, advance their careers and feel a true sense of belonging.

• Nuclear Operations: Our nuclear fleet, including our owned output from the Salem and South Texas Project (STP) Generating Stations, produced 44,160 gigawatt-hours (GWhs) in the second quarter of 2026, compared with 45,170 GWhs in the second quarter of 2025. Excluding Salem and STP, our nuclear plants at ownership achieved a 93.0% capacity factor for the second quarter of 2026, compared with 94.8% for the second quarter of 2025. There were 86 planned refueling outage days in the second quarter of 2026 and 41 in the second quarter of 2025 for sites we operate. There were 20 non-refueling outage days in the second quarter of 2026 and 22 in the second quarter of 2025 for sites we operate.

• Natural Gas, Oil, and Renewables Operations: As a result of our expanded fleet following the acquisition of Calpine in January 2026, we now consider Equivalent Forced Outage Factor (EFOF) to be a key operational metric beginning in 2026. EFOF represents the percentage for which a generating unit is not available due to forced outages and forced deratings in a given period. The EFOF of our natural gas, oil, and pumped-storage hydro fleet for the second quarter of 2026 is 6.2%. Renewable energy capture for our wind, solar and run-of-river hydro fleet was 96.0% in the second quarter of 2026, compared with 96.1% in the second quarter of 2025.

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 25.5% for the three months ended June 30, 2026 and 2025. The following table provides a reconciliation between GAAP Net Income (Loss) Attributable to Common Shareholders and Adjusted (non-GAAP) Operating Earnings for the three months ended June 30, 2026 compared to the same period in 2025.
