Baltimore (Nov. 8, 2022) — Constellation Energy Corporation (Nasdaq: CEG) today reported its financial results for the third quarter of 2022.

“We reported solid quarterly financial and operational results, and our long-term outlook has strengthened significantly with passage of the landmark Inflation Reduction Act, which will allow us to create value and drive America’s clean energy transition,” said Joe Dominguez, president and CEO of Constellation. “Support for carbon-free energy in the legislation creates opportunities for us to extend the life of our nuclear fleet past mid-century and pursue hydrogen production to slash emissions from difficult-to-decarbonize sectors of the economy. Now there are both state and federal policies that recognize the essential role our zero-carbon nuclear assets must play in achieving our nation’s climate goals, preserving jobs and ensuring a secure energy supply.”

“The commercial business continues to post better-than-expected results, and our nuclear fleet remains the most reliable and cost-efficient in the business despite unplanned outages during the quarter,” said Dan Eggers, chief financial officer of Constellation.

“S&P upgraded our credit rating to BBB due to our strong balance sheet and the clear support for carbon-free energy in the IRA. Adjusted third-quarter EBITDA of $592 million was in line with our expectations, and we are narrowing our full-year EBITDA range to $2.45 billion to $2.65 billion.”

Our GAAP Net Loss for the third quarter of 2022 was ($188) million, down from $607 million GAAP Net Income in the third quarter of 2021. Adjusted EBITDA (non-GAAP) for the third quarter of 2022 decreased to $592 million from $967 million in the third quarter of 2021. For the reconciliations of GAAP Net (Loss) Income to Adjusted EBITDA (non-GAAP), refer to the tables beginning on page 3.

Adjusted EBITDA (non-GAAP) in the third quarter of 2022 primarily reflects:

•Decreased capacity revenues, increased labor, contracting and material costs and the absence of gains on CTV investments realized in the prior year.

•Inflation Reduction Act Signed into Law: On Aug. 16, 2022, Congress passed and President Biden signed into law the Inflation Reduction Act of 2022, which, among other things, includes federal tax credits, certain of which are transferable or fully refundable, for clean energy technologies including existing nuclear plants and hydrogen production facilities. The Nuclear Production Tax Credit (PTC) recognizes the contributions of carbon-free nuclear power by providing a federal tax credit of up to $15/MWh, subject to phase-out, beginning in 2024 and continuing through 2032. The Hydrogen PTC provides a 10-year federal tax credit of up to $3/kilogram for clean hydrogen produced after 2022 from facilities that begin construction prior to 2033. Both the Nuclear and Hydrogen PTCs include adjustments for inflation. The Hydrogen PTC creates additional opportunities for our nuclear fleet to enable decarbonization of other industries through the production of clean hydrogen. With this policy support, we expect that many of our nuclear assets will operate through the end of the Nuclear PTC period.

•Our issuer credit rating upgraded to BBB with positive outlook: On Oct. 13, 2022, S&P rating services raised our issuer credit rating (ICR) to ‘BBB’ from ‘BBB-’, reflecting S&P’s view of a material improvement in our business risk profile. S&P cited the passage of the Inflation Reduction Act of 2022 as a material credit positive for us. In S&P’s view, the nuclear production tax credits in the legislation provide long-term visibility into the cash flows for our nuclear fleet and benefit potential future hydrogen production.

•Seeking license renewals for Clinton and Dresden Nuclear Power Plants: On Oct. 31, 2022, we announced our intent to seek renewal of the operating licenses for our Clinton and Dresden nuclear power plants. These renewals, if granted, would allow the plants to operate for an additional 20 years. Clinton could operate until 2047 and Dresden could operate until 2049 (Unit 2) and 2051 (Unit 3). The continued operation of the two zero-carbon plants is enabled by state and federal legislation that recognizes the unique environmental and economic value of nuclear energy.

•Published our first Sustainability Report detailing our strategy to lead the clean energy transition and fight the climate crisis: On Sept. 7, 2022, we released our first sustainability report, highlighting our efforts to accelerate the transition to a carbon-free future, mitigate the climate crisis and support energy equity and environmental justice. The report details our innovative clean energy center model, powered by always-on, carbon-free nuclear plants, that will bring together new and emerging technologies to help decarbonize other polluting sectors of the economy. Additionally, the report outlines the need to begin transitioning toward a more accurate carbon accounting approach, along with the tools we are helping to pioneer, such as the hourly carbon-free energy matching platform to help our customers achieve true-zero emissions.

•Executed long-term agreement with the City of Chicago supporting 300 MW of renewables development through our Constellation Offsite Renewables (CORe) product: On Aug. 8, 2022, we announced an agreement with the City of Chicago to help meet the City’s commitment to purchase renewable energy for all its facilities and operations by 2025. In addition to enabling the development of Swift Current Energy’s 590 MW Double Black Diamond solar project, the agreement makes the City of Chicago one of the largest U.S. cities to commit to clean energy and will help reduce the City’s carbon footprint by more than 290,000 metric tons per year.

•Our leaders joined State and Federal officials to celebrate progress on nation’s first nuclear-powered clean hydrogen facility: On Sept. 28, 2022, leaders from the U.S. Department of Energy (DOE), the New York State Energy Research and Development Authority (NYSERDA), and the New York State Public Service Commission (PSC) joined our leaders and employees at Nine Mile Point Nuclear Generating Station (NMP) to celebrate progress on the nation’s first nuclear-powered clean hydrogen production facility, which will begin production by the end of the year. Last year, as part of a $5.8 million award, DOE approved moving forward with construction and installation of an electrolyzer system at NMP that will separate hydrogen and oxygen molecules in water to produce carbon-free hydrogen. In addition, NYSERDA recently announced $12.5 million in funding to help demonstrate hydrogen fuel cell technology at the plant to provide long-duration energy storage for the electric grid. The hydrogen fuel cell project at NMP is currently being designed and is expected to be operational in 2025. These projects will demonstrate the viability of hydrogen electrolyzer and fuel cell technologies, setting the stage for possible deployment at other clean energy centers in our nuclear fleet. As part of our broader decarbonization strategy, we are currently working with public and private entities representing every phase in the hydrogen value chain to pursue development of regional hydrogen production and distribution hubs, including participation in the Midwest Alliance for Clean Hydrogen or "MachH2" hydrogen hub.

•Nuclear Operations: Our nuclear fleet, including our owned output from the Salem Generating Station, produced 43,794 gigawatt-hours (GWhs) in the third quarter of 2022, compared with 44,350 GWhs in the third quarter of 2021. Excluding Salem, our nuclear plants at ownership achieved a 96.4% capacity factor for the third quarter of 2022, compared with 97.7%1 for the third quarter of 2021. There were five planned refueling outage days in the third quarter of 2022 and 22 in the third quarter of 2021. There were 26 non-refueling outage days in the third quarter of 2022 and none in the third quarter of 2021.

•Natural Gas, Oil, and Renewables Operations: The dispatch match rate for our gas and hydro fleet was 98.8% in the third quarter of 2022, compared with 99.4% in the third quarter of 2021. Energy capture for the wind and solar fleet was 95.7% in the third quarter of 2022, compared with 95.8% in the third quarter of 2021.

________

1Prior year capacity factor was previously reported as 96.0%. The update reflects a change to the ratio from using the full average annual mean capacity to the net monthly mean capacity when calculating capacity factor. There is no change to actual output and the full year capacity factor would be the same under both methodologies.

Adjusted EBITDA (non-GAAP) for the third quarter of 2022 and 2021, respectively, does not include the following items that were included in our reported GAAP Net (Loss) Income:

We will discuss third quarter 2022 earnings in a conference call scheduled for today at 10 a.m. Eastern Time. The webcast and associated materials can be accessed at https://investors.constellationenergy.com.
