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.”

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:

•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

•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.

•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.

•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.

•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
