**CONSTELLATION REPORTS THIRD QUARTER 2025 RESULTS**

**Earnings Release Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• GAAP Net Income of $2.97 per share and Adjusted (non-GAAP) Operating Earnings of $3.04 per share for the third quarter of 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Narrowing full-year 2025 Adjusted (non-GAAP) Operating Earnings guidance range to $9.05 – $9.45 per share

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Conowingo Dam received a water quality certification from the Maryland Department of the Environment (MDE) clearing the way for the re-licensing and continued operation of the dam's hydroelectric facility

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

"We achieved one of the highest operating quarters for our nuclear fleet and advanced major milestones like our historic settlement with Maryland for continued operations of the Conowingo dam," said Joe Dominguez, president and CEO of Constellation. "Momentum continues to build around reliable, clean nuclear energy as a cornerstone of America's energy strategy. With growing recognition of nuclear's role in powering the data economy and supporting reliability and affordability for consumers, Constellation is positioned to help our regions and nation grow, while continuing to deliver benefits for our customers, communities, and owners."

"Constellation delivered adjusted operating earnings of $3.04 per share this quarter, up from $2.74 per share in Q3 of last year," said Dan Eggers, chief financial officer, Constellation. "We continue to execute well operationally and financially, supported by strong nuclear and commercial performance. We are narrowing our full-year adjusted operating earnings guidance range to $9.05 – $9.45 per share. Nuclear energy is core to the nation's clean energy and reliability goals, and the strength of our existing fleet – including the potential for life extensions and uprates – positions us to meet growing customer demand. As we approach the close of the Calpine transaction, we are excited to bring these two great companies together and harness the capabilities of the combined company to meet the needs of America with clean, reliable power and innovative products for our customers."

**Third Quarter 2025**

Our GAAP Net Income for the third quarter of 2025 decreased to $2.97 per share from $3.82 per share in the third quarter of 2024. Adjusted (non-GAAP) Operating Earnings for the third quarter of 2025 increased to $3.04 per share from $2.74 per share in the third 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 third quarter of 2025 primarily reflects:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Favorable market and portfolio conditions and impact of nuclear outages, partially offset by lower nuclear PTC revenue due to higher anticipated gross receipts for the year

**Recent Developments and Third Quarter Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Conowingo Dam:** In September 2025, we reached a settlement agreement with MDE, Lower Susquehanna Riverkeeper Association, and Waterkeepers Chesapeake, that resolves all outstanding issues related to obtaining a water quality certification from MDE. As a result, MDE issued a water quality certification, clearing the way for the re-licensing and continued operation of our Conowingo hydroelectric facility. The terms of the agreement include operational improvements and commitments for water quality and resiliency, trash and debris removal, aquatic life passage, freshwater mussel restoration, dredging and invasive species management.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Nuclear Operations:** Our nuclear fleet, including our owned output from the Salem and South Texas Project (STP) Generating Stations, produced 46,477 gigawatt-hours (GWhs) in the third quarter of 2025, compared with 45,510 GWhs in the third quarter of 2024. Excluding Salem and STP, our nuclear plants at ownership achieved a 96.8% capacity factor for the third quarter of 2025, compared with 95.0% for the third quarter of 2024. There were 23 planned refueling outage days in the third quarter of 2025 and 37 in the third quarter of 2024 for sites we operate. There were five non-refueling outage days in the third quarter of 2025 and 20 in the third quarter of 2024 for sites we operate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Natural Gas, Oil, and Renewables Operations:** The dispatch match rate for our gas and pumped storage fleet was 95.5% in the third quarter of 2025, compared with 98.2% in the third quarter of 2024. Renewable energy capture for our wind, solar and run-of-river hydro fleet was 96.8% in the third quarter of 2025, compared with 96.0% in the third 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 25.6% and 25.5% for the three months ended September 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 54.9% and 54.6% for the three months ended September 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.

**Cautionary Statements Regarding Forward-Looking Information**

This press release contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that are subject to risks and uncertainties. Words such as "could," "may," "expects," "anticipates," "will," "targets," "goals," "projects," "intends," "plans," "believes," "seeks," "estimates," "predicts," and variations on such words, and similar expressions that reflect our current views with respect to future events and operational, economic, and financial performance, are intended to identify such forward-looking statements. These forward-looking statements include, but are not limited to, statements regarding the proposed transaction between Constellation and Calpine Corporation, the expected closing of the proposed transaction and the timing thereof. This includes statements regarding the financing of the proposed transaction and the pro forma combined company and its operations, strategies and plans, enhancements to investment-grade credit profile, synergies, opportunities and anticipated future performance and capital structure, and expected accretion to earnings per share and free cash flow. Information adjusted for the proposed transaction should not be considered a forecast of future results.

Forward-looking statements are based on current expectations, estimates and assumptions that involve a number of risks and uncertainties that could cause actual results to differ materially from those projected. The factors that could cause actual results to differ materially from the forward-looking statements made by Constellation Energy Corporation and Constellation Energy Generation, LLC, (the Registrants) include those factors discussed herein, as well as the items discussed in (1) the Registrants' 2024 Annual Report

The Registrants report their financial results in accordance with accounting principles generally accepted in the United States (GAAP). Constellation supplements the reporting of financial information determined in accordance with GAAP with certain non-GAAP financial measures, including: • Adjusted Operating Earnings (and/or its per share equivalent) exclude certain costs, expenses, gains and losses and other specified items, including mark-to-market adjustments from economic hedging activities, interest rate swaps, and fair value adjustments related to gas imbalances and equity investments, decommissioning related activity, asset impairments, certain amounts associated with plant retirements and divestitures, pension and other post-employment benefits (OPEB) non-service credits, and other items as set forth in the Appendix • Free cash flows before growth (FCFbG) is cash flows from operations less capital expenditures under GAAP for maintenance and nuclear fuel, equity investments, and adjusted for changes in collateral and non-recurring costs-to-achieve (CTA) • Adjusted gross margin is defined as adjusted operating revenues less adjusted purchased power and fuel expense, excluding revenue related to decommissioning, gross receipts tax, variable interest entities, and net of direct cost of sales for certain end-user businesses – Adjusted operating revenues excludes the mark-to-market impact of economic hedging activities due to the volatility and unpredictability of the future changes in commodity prices – Adjusted purchased power and fuel excludes the mark-to-market impact of economic hedging activities and fair value adjustments related to gas imbalances due to the volatility and unpredictability of the future changes in commodity prices • Adjusted operating and maintenance (O&M) excludes direct cost of sales for certain end-user businesses, Asset Retirement Obligation (ARO) accretion expense from unregulated units and decommissioning costs that do not affect profit and loss, the impact from operating and maintenance expense related to variable interest entities at Constellation, and other items as set forth in the reconciliation in the Appendix Due to the forward-looking nature of our Adjusted Operating Earnings guidance, Projected Adjusted Gross Margin, and Projected Free Cash Flow Before Growth, we are unable to reconcile these non-GAAP financial measures to the comparable GAAP measures 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. Non-GAAP Financial Measures 3

Since it is above the $44.75/MWh PTC phase out units would not receive PTC value • When revenues fall below the $44.75/MWh phase out, the PTC will provide revenue support for the units, bringing effective realized revenues back to $44.75 • Assuming revenues of $35.00/MWh, the orange line, we would expect units to receive $7.80/MWh PTC, bringing the total value the unit would receive to $42.80/MWh and $45.40/MWh (2) on a tax adjusted basis Competitive Unit Payoff $35/MWh $47/MWh PTC provides support from $26/MWh - $44.75/MWh (1) See H.R. 5376 for additional details; all numbers assume that prevailing wage requirements are satisfied (2) Grossed up assuming 25% tax rate
