**CONSTELLATION REPORTS FIRST QUARTER 2026 RESULTS**

**Earnings Release Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• GAAP Net Income of $4.49 per share and Adjusted (non-GAAP) Operating Earnings of $2.74 per share for the first quarter of 2026

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Affirming full year 2026 Adjusted Operating Earnings guidance of $11.00 - $12.00 per share

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Commissioning of 105 megawatt (MW) Pastoria Solar Project

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 460 MW Pin Oak Creek Energy Center achieves commercial operation

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net metering application for co-location of a data center at our Freestone site approved

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ranked #1 on Barron's Most Sustainable U.S. Companies for 2026

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our employees demonstrated their commitment to our communities by volunteering at over 150 events across 15 states and Washington, D.C. during April 2026, in honor of National Volunteer Month

**Baltimore (May 11, 2026)** — Constellation Energy Corporation (Nasdaq: CEG) today reported its financial results for the first quarter of 2026.

"America needs reliable, clean power and Constellation is built to meet this demand with the strength of our fleet and the solutions we're delivering for customers," said Joe Dominguez, president and CEO of Constellation. "Right now, our focus is on execution – operating at a high level, integrating two great companies, bringing new resources to market, and navigating a changing regulatory environment – led by the women and men who power our business every day."

"Our first-quarter results reflect continued operational excellence from our entire organization," said Shane Smith, executive vice president and chief financial officer of Constellation. "We are affirming our full-year guidance and the expectation of strong, visible cash flow that supports our strategic capital allocation framework."

------

**First Quarter 2026**

Our GAAP Net Income for the first quarter of 2026 increased to $4.49 per share from $0.38 per share in the first quarter of 2025. Adjusted (non-GAAP) Operating Earnings for the first quarter of 2026 increased to $2.74 per share from $2.14 per share in the first 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 first quarter of 2026 primarily reflects:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The addition of Calpine, favorable stock-based compensation, nuclear PTC portfolio and market and portfolio conditions, partially offset by unfavorable nuclear outages

**Recent Developments and First Quarter Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Pastoria Solar Project Comes Online:** On April 16, 2026 we celebrated the commissioning of the 105 MW Pastoria Solar Project, the largest renewable energy project contracted by the California Department of Water Resources (DWR) to date in its mission to fully decarbonize its operations by 2035. The Pastoria Solar Project connects to the grid through the interconnection facilities at the highly efficient 750 MW natural gas-fired combined-cycle generating facility. Also, co-located with the Pastoria Solar Project is the 80 MW/320 MWh Battery Energy Storage System, which will be coming online during the spring/summer of 2026. The Pastoria Power Bank is contracted and supported by a 15-year power purchase agreement with Pacific Gas and Electric Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Pin Oak Creek Energy Center Reaches Commercial Operation:** On April 30, 2026, our Pin Oak Creek Energy Center achieved commercial operation. Pin Oak is a 460 MW, state-of-the-art natural gas facility designed to provide reliable, dispatchable power to the ERCOT grid. As a peaking facility, it is built to operate when demand is highest and reliability matters most, while also maintaining the flexibility to run longer if system conditions require it. The project is a direct response to Texas' continued growth and increasing electricity demand across homes, businesses, and industry. Pin Oak Creek will play a critical role in strengthening grid reliability and supporting the state's economic momentum.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Freestone Net Metering Application Approved:** The PUCT has approved the net metering application for the co-location of a Cyrus One data center at our Freestone site, subject to conditions. In February we signed a 380 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. We also entered into an exclusive agreement to provide power, grid connectivity and site infrastructure for Phase 2, which will be an additional 380 MW.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Ranked #1 on Barron's Most Sustainable U.S. Companies for 2026:** We earned the No. 1 spot on Barron's annual "Most Sustainable U.S. Companies" rankings, which evaluate the country's 1,000 largest publicly traded companies on 230 performance indicators including environmental impact, workforce development and community support.

------

&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 44,666 gigawatt-hours (GWhs) in the first quarter of 2026, compared with 45,582 GWhs in the first quarter of 2025. Excluding Salem and STP, our nuclear plants at ownership achieved a 92.3% capacity factor for the first quarter of 2026, compared with 94.1% for the first quarter of 2025. There were 99 planned refueling outage days in the first quarter of 2026 and 88 in the first quarter of 2025 for sites we operate. There were no non-refueling outage days in the first quarter of 2026 and 2025 for sites we operate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **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 first quarter of 2026 is 4.5%. Renewable energy capture for our wind, solar and run-of-river hydro fleet was 96.7% in the first quarter of 2026, compared with 96.2% in the first 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 March 31, 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 March 31, 2026 compared to the same period in 2025.

_______

(a)Amounts may not sum due to rounding. Earnings per share amount is based on average diluted common shares outstanding of 354 million and 314 million for the three months ended March 31, 2026 and 2025, respectively.

(b)Includes unrealized gains and losses on economic hedges, interest rate swaps, and fair value adjustments related to gas imbalances and equity investments.

(c)Reflects all gains and losses associated with NDTs, ARO accretion, ARC depreciation, ARO remeasurement, and impacts of contractual offset for Regulatory Agreement Units. The tax effects of Regulatory Agreement Units result in a 100% effective tax rate under contractual offset accounting. Additionally, the tax effects of NDT investment returns result in different effective tax rates depending on whether the underlying funds are held within qualified or non-qualified trusts.

(d)In 2026, reflects the non-cash impacts of the amortization of certain commodity contracts recorded at fair value associated with the Calpine acquisition.

(e)Reflects costs associated with the completion of the Calpine merger and subsequent integration of its operations. Certain of these transaction-related expenses are not tax deductible.

(f)Represents elimination of the noncontrolling interest portion of certain adjustments included above.

**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.

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 adjustments for unrealized gains or losses on economic hedges, 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 unrealized gains or losses on economic hedging activities due to the volatility and unpredictability of the future changes in commodity prices – Adjusted purchased power and fuel excludes the unrealized gains or losses on 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.

This information is intended to enhance an investor's overall understanding of period over period financial results and provide an indication of Constellation's operating performance by excluding items that are considered by management to be not directly related to the ongoing operations of the business. In addition, this information is among the primary indicators management uses as a basis for evaluating performance, allocating resources, setting incentive compensation targets and planning and forecasting of future periods. These non-GAAP financial measures are not a presentation defined under GAAP and may not be comparable to other companies' presentations of similarly titled financial measures. Constellation has provided these non-GAAP financial measures as supplemental information and in addition to the financial measures that are calculated and presented in accordance with GAAP. These non-GAAP measures should not be deemed more useful than, a substitute for, or an alternative to the most comparable GAAP measures provided in the materials presented. Non-GAAP financial measures are identified by the phrase "non-GAAP" or an asterisk (\*). Reconciliations of these non-GAAP measures to the most comparable GAAP measures are provided in the appendices and attachments to this presentation. Non-GAAP Financial Measures Continued 4

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/MWh • 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
