CONSTELLATION REPORTS THIRD QUARTER 2023 RESULTS
Earnings Release Highlights
GAAP Net Income of $731 million and Adjusted EBITDA (non-GAAP) of nearly $1.2 billion for the third quarter of 2023
Raising guidance range for full year 2023 Adjusted EBITDA (non-GAAP) to $3,800 million to $4,000 million
Delivering on our commitment to shareholders:
Expanded the nation's largest, highly reliable carbon-free nuclear fleet by acquiring a 44% stake in South Texas Project Electric Generating Station
Repurchased $250 million of shares, returning value to shareholders and completing three quarters of our $1.0 billion share repurchase program
Achieved major milestone in bid to build world's largest nuclear-powered hydrogen production facility with U.S. Department of Energy grant of up to $1.0 billion for MachH2 hydrogen hub
Reached agreement with ComEd, one of the nation's largest utilities, to power its 54 metered facilities with locally produced, carbon-free nuclear energy, every hour of every day
Earned 2023 Great Place to Work® certification based on positive ratings from our employees on their experience working at Constellation

Baltimore (Nov. 6, 2023) — Constellation Energy Corporation (Nasdaq: CEG) today reported its financial results for the third quarter of 2023.

1


“Our continued strong performance this quarter is the result of pairing the nation’s largest clean energy fleet with an unmatched commercial business, allowing us to produce affordable and reliable carbon-free energy when and where American families and businesses need it,” said Joe Dominguez, president and CEO of Constellation. “This combination of businesses is the fundamental strength of our strategy. It allows us to help customers like Microsoft and ComEd manage their energy costs in a volatile market, while also lowering their carbon emissions with clean energy matched to their use in every hour of every day. We continue to execute our growth strategy, closing on the South Texas Project transaction ahead of schedule and moving forward with $1.5 billion in growth spending on equipment to increase the output of our nuclear plants, wind repowering and pursuit of a nuclear-powered clean hydrogen facility as part of a multi-state hub.”

“Our generation fleet performed at peak levels during a summer of record heat, while our commercial business continued to win new business and realize higher margins,” said Dan Eggers, executive vice president and chief financial officer. “Our gross margin outlook for 2023 is now $850 million higher than our expectations at the start of the year and our outlook for 2024 has increased. Based on current market conditions and the continued strength of our operations, we are raising 2023 adjusted EBITDA guidance to a $3.9 billion mid-point and narrowing the range to $3.8 billion to $4 billion.”
Third Quarter 2023
Our GAAP Net Income for the third quarter of 2023 increased to $731 million from ($188) million GAAP Net Loss in the third quarter of 2022. Adjusted EBITDA (non-GAAP) for the third quarter of 2023 increased to $1,199 million from $592 million in the third quarter of 2022. For the reconciliations of GAAP Net Income (Loss) to Adjusted EBITDA (non-GAAP), refer to the tables beginning on page 3.
Adjusted EBITDA (non-GAAP) in the third quarter of 2023 primarily reflects:
Favorable market and portfolio conditions; partially offset by unfavorable labor, contracting, and materials, and decreased ZEC revenue.
Recent Developments and Third Quarter Highlights
Delivering on Our Capital Allocation Promises: In alignment with our capital and strategic plan, on November 1, 2023 we completed our acquisition of a 44% undivided ownership interest in the South Texas Project Nuclear Generating Station, a 2,645-megawatt, dual-unit nuclear plant located about 90 miles southwest of Houston, for $1.75 billion. We issued senior notes with net proceeds of approximately $1.4 billion which was in part used to fund the acquisition. This acquisition is complementary to and aligned strategically with our existing clean energy business operations.

We’ve also continued our share repurchase program, repurchasing over 2.3 million shares for a total of $250 million in the third quarter 2023. To date, we have successfully repurchased approximately 8.5 million shares, utilizing $756 million, inclusive of taxes and transaction costs, of the $1 billion authorization.

Clean Hydrogen Hub Awarded: We are excited to be a major participant in the MachH2 hydrogen hub recently selected for up to $1 billion by the Department of Energy. A portion of the hub funding will be used to build the world's largest nuclear-powered clean hydrogen production facility at our LaSalle Clean Energy Center in Illinois. The project will produce an estimated 33,450 tons of clean hydrogen each year and create thousands of good-paying jobs. We estimate the facility will cost approximately $900 million, with a portion of the MachH2 award offsetting the project’s cost.

Major Utility Carbon-Free Energy Matching Deal: We signed a historic agreement with Commonwealth Edison (ComEd) to power its 54 metered facilities with locally produced carbon-free nuclear energy, every hour of every day. ComEd’s hourly carbon-free energy purchase will match its anticipated electricity use of approximately 65,000 megawatt-hours annually. This agreement follows a similar deal between Constellation and Microsoft announced in the second quarter of 2023 to power one of its Virginia data centers with nearly 100 percent carbon-free nuclear energy. Together, the two transactions are setting a new standard for how companies across the U.S. can achieve real emissions reductions.

2023 Great Place to Work Certification: In the third quarter 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, 81% of those who responded said it is a great place to work – about 24 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.

Nuclear Operations: Our nuclear fleet, including our owned output from the Salem Generating Station, produced 44,125 gigawatt-hours (GWhs) in the third quarter of 2023, compared with 43,794 GWhs in the third quarter of 2022. Excluding Salem, our nuclear plants at ownership achieved a 97.2% capacity factor for the third quarter of 2023, compared with 96.4% for the third quarter of 2022. There were 20 planned refueling outage days in the third quarter of 2023 and five in the third quarter of 2022. There were 10 non-refueling outage days in the third quarter of 2023 and 26 in the third quarter of 2022.

Natural Gas, Oil, and Renewables Operations: The dispatch match rate for our fleet was 98.5% in the third quarter of 2023, compared with 98.7%1 in the third quarter of 2022. Renewable energy capture for our fleet was 96.6% in the third quarter of 2023, compared with 96.4%1 in the third quarter of 2022.















________
1Prior year dispatch match and energy capture was previously reported as 98.8% and 95.7%, respectively. The update reflects a change to include the Conowingo run-of-river hydroelectric operational performance within renewable energy capture, and remove the performance from dispatch match.

Non-GAAP Financial Measures
In analyzing and planning for our business, we supplement our use of net income as determined under generally accepted accounting principles in the United States (GAAP), with Adjusted EBITDA (non-GAAP) as a performance measure. Adjusted EBITDA (non-GAAP) reflects an additional way of viewing our business that, when viewed with our GAAP results and the accompanying reconciliation to GAAP net income included above, may provide a more complete understanding of factors and trends affecting our business. Adjusted EBITDA (non-GAAP) should not be relied upon to the exclusion of GAAP financial measures and is, by definition, an incomplete understanding of our business, and must be considered in

conjunction with GAAP measures. In addition, Adjusted EBITDA (non-GAAP) is neither a standardized financial measure, nor a presentation defined under GAAP and may not be comparable to other companies’ presentations or deemed more useful than the GAAP information provided elsewhere in this press release and earnings release attachments. We have provided the non-GAAP financial measure as supplemental information and in addition to the financial measures that are calculated and presented in accordance with GAAP. Adjusted EBITDA (non-GAAP) should not be deemed more useful than, a substitute for, or an alternative to the most comparable GAAP Net Income measure provided in this earnings release and attachments. A reconciliation of projected Adjusted EBITDA, which is a forward-looking non-GAAP financial measure, to the most directly comparable GAAP financial measure, is not provided because we are unable to provide such reconciliation without unreasonable effort. The inability to provide each reconciliation is due to the unpredictability of the amounts and timing of events affecting the items we exclude from the non-GAAP measure. This press release and earnings release attachments provide reconciliations of Adjusted EBITDA (non-GAAP) to the most directly comparable financial measures calculated and presented in accordance with GAAP, are posted on our website: www.ConstellationEnergy.com, and have been furnished to the Securities and Exchange Commission on Form 8-K on November 6, 2023.

Cautionary Statements Regarding Forward-Looking Information 2


 
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 EBITDA represents earnings before interest, income taxes, depreciation and amortization, and excludes certain costs, expenses, gains and losses and other specified items, including mark-to-market adjustments from economic hedging activities 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, separation related costs and other items as set forth in the Appendix. Includes nuclear fuel amortization expense. • Adjusted cash flows from operations primarily includes net cash flows from operating activities and Collection of Deferred Purchase Price (DPP) related to the revolving accounts receivable arrangement, which is presented in cash flows from investing activities under GAAP • Free cash flows before growth (FCFbg) is adjusted cash flows from operations less capital expenditures under GAAP for maintenance and nuclear fuel, non- recurring capital expenditures related to separation and Enterprise Resource Program (ERP) system implementation, changes in collateral, net merger and acquisitions, and equity investments and other items as set forth in the Appendix • 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 • Total gross margin is defined as adjusted operating revenues less adjusted purchased power and fuel expense, excluding revenue related to decommissioning, gross receipts tax, production tax credits (PTCs), variable interest entities, and net of direct cost of sales for certain end-user businesses • 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 some projected non-GAAP financial measures, reconciliations of projected non-GAAP financial measures to the most directly comparable GAAP financial measure is not provided because we are unable to provide such reconciliation without unreasonable effort. The inability to provide each reconciliation is due to the unpredictability of the amounts and timing of events affecting the items we exclude from the non-GAAP measures. Non-GAAP Financial Measures 3


 
This information is intended to enhance an investor’s overall understanding of period over period financial results and provide an indication of Constellation’s baseline 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, except for the reconciliation for total gross margin*, which appears on slide 28 of this presentation.

• The Zero Emission Standard, passed in December 2016, requires the Illinois Power Agency (IPA) to procure contracts with zero emission facilities for zero emission credits (ZECs) • The program has a 10-year duration that commenced with the 2017/2018 planning year and runs through May 2027 • The IPA calculates the ZEC price for each planning year based on the social cost of carbon and a market price index relative to a baseline market price index – The social cost of carbon was set at $16.50/MWh for the first six years of the program and then increases at $1/MWh per year beginning in the 2023/2024 planning period – The market price index resets each year (1), while the baseline market price index was set at $31.40/MWh • Total compensation is limited by an annual cap designed to limit the cost of ZECs to each utility’s customers – There is a “banking” mechanism, where, for ZECs delivered that exceed the annual cap each year they may be paid in subsequent years if the payments would not exceed the annual cap in the year paid – In each planning year since the program commenced on June 1, 2017, we have delivered ZECs to the utilities in excess of the annual compensation cap • For the June 1, 2023 to May 31, 2024 planning year the ZEC price has been established at $0.30 per ZEC, subject to an annual cap of $224 million. ZECs generated and delivered during this planning year will not exceed the annual cap, providing available funds to compensate for ZECs delivered but not paid in prior planning years.

Expected generation assumes 14 refueling outages in 2023 and 13 in 2024 at Constellation-operated nuclear plants and Salem. Expected generation assumes capacity factors of 94.1% and 94.2% in 2023 and 2024, respectively at Constellation-operated nuclear plants, at ownership. These estimates of expected generation in 2023 and 2024 do not represent guidance or a forecast of future results as we have not completed its planning or optimization processes for those years. (2) Midwest (Total) expected generation includes generation from CMC plants of 54,600 GWh in 2023 and 53,800 GWh in 2024 (3) Percent of expected generation hedged is the amount of equivalent sales divided by expected generation. It includes all hedging products, such as wholesale and retail sales of power, options and swaps. The Midwest values in the table reflect IL plants receiving CMC payments as 100% hedged. To align with the Midwest EREP, however, one should exclude plant and hedge volumes associated with CMC payments. New York values include the effect of the New York ZEC. (4) Effective realized energy price is representative of an all-in hedged price, on a per MWh basis, at which expected generation has been hedged. It is developed by considering the energy revenues and costs associated with our hedges and by considering the natural gas that has been purchased to lock in margin. It excludes uranium costs, RPM capacity, ZEC and CMC revenues, but includes the mark-to-market value of capacity contracted at prices other than RPM clearing prices including our load obligations. It can be compared with the reference prices used to calculate open gross margin* in order to determine the mark-to-market value of Constellation’s energy hedges.
