Exelon Corporation (NASDAQ:EXC) today reported its financial results for the second quarter of 2023.

"In the second quarter, we reported solid financial results, and our local energy companies across the country continue to prove that they are best in class – with three of our four operating companies having best-on-record performance in outage frequency and outage duration last quarter," said Exelon President and CEO, Calvin Butler. "We deliver this performance while remaining steadfast in our commitment to a sustainable energy future. We are modernizing the grid, enabling further electrification and decarbonization. I'm confident we will continue strengthening Exelon's financial position while prioritizing the health of our customers and communities."

"Exelon's performance remained strong into the second quarter of the year, reporting Adjusted (non-GAAP) Operating Earnings of $0.41 per share, which is in line with expectations," said Exelon Executive Vice President and CFO Jeanne Jones. "Through the first half of 2023, we have deployed $3.6B of investments needed to lead the energy transformation for our customers. We look forward to closing out the second half of 2023 equally strong executing on the remaining $7.2 billion of investments. We reaffirm our full year Adjusted (non-GAAP) Operating Earnings guidance range of $2.30 to $2.42 per share."

Second Quarter 2023

Exelon's GAAP Net Income from Continuing Operations for the second quarter of 2023 decreased to $0.34 per share from $0.47 GAAP Net Income from Continuing Operations per share in the second quarter of 2022. Adjusted (non-GAAP) Operating Earnings for the second quarter of 2023 decreased to $0.41 per share from $0.44 per share in the second quarter of 2022. For the reconciliations of GAAP Net Income from Continuing Operations to Adjusted (non-GAAP) Operating Earnings, refer to the tables beginning on page 4.

Adjusted (non-GAAP) Operating Earnings in the second quarter of 2023 primarily reflect:

Consistent utility earnings primarily due to higher electric distribution formula rate earnings at ComEd from higher allowed ROE due to an increase in U.S. treasury rates and the impacts of higher rate base, rate increases at PECO, BGE, and PHI, and carrying costs related to the carbon mitigation credit (CMC) regulatory asset at ComEd. This was partially offset by unfavorable weather at PECO, higher depreciation expense at PECO, and higher interest expense at BGE.
Higher costs at the Exelon holding company primarily due to higher interest expense.

Operating Company Results¹

ComEd

ComEd's second quarter of 2023 GAAP Net Income increased to $249 million from $227 million in the second quarter of 2022. ComEd's Adjusted (non-GAAP) Operating Earnings for the second quarter of 2023 increased to $251 million from $229 million in the second quarter of 2022, primarily due to increases in electric distribution formula rate earnings (reflecting higher allowed ROE due to an increase in U.S. Treasury rates and the impacts of higher rate base) and carrying costs related to the CMC regulatory asset. Due to revenue decoupling, ComEd's distribution earnings are not affected by actual weather or customer usage patterns.

PECO

PECO's second quarter of 2023 GAAP Net Income decreased to $97 million from $133 million in the second quarter of 2022. PECO's Adjusted (non-GAAP) Operating Earnings for the second quarter of 2023 decreased to $98 million from $134 million in the second quarter of 2022, primarily due to unfavorable weather and an increase in depreciation expense, partially offset by gas distribution rate increases.

BGE

BGE's second quarter of 2023 GAAP Net Income increased to $42 million from $37 million in the second quarter of 2022. BGE's Adjusted (non-GAAP) Operating Earnings for the second quarter of 2023 increased to $43 million from $38 million in the second quarter of 2022, primarily due to favorable impacts of the multi-year plans, offset by an increase in interest expense. Due to revenue decoupling, BGE's distribution earnings are not affected by actual weather or customer usage patterns.

Due to revenue decoupling, PHI's distribution earnings related to Pepco Maryland, DPL Maryland, Pepco District of Columbia, and ACE are not affected by actual weather or customer usage patterns.

Recent Developments and Second Quarter Highlights

Pepco Maryland Electric Rate Case: On May 16, 2023, Pepco filed an application for a three-year cumulative multi-year plan for April 1, 2024 through March 31, 2027, with the MDPSC. Pepco requested total electric revenue requirement increases of $74 million, $60 million, and $60 million in 2024, 2025, and 2026, respectively. The plan contains a proposed nine-month extension period with a requested revenue requirement increase of $20 million effective April 1, 2027 through December 31, 2027. The electric revenue requirement increases reflect a requested ROE of 10.5%. Requested revenue requirement increases will be used to recover capital investments designed to advance system-readiness and support Maryland's climate and clean energy goals.

Non-GAAP Financial Measures

In addition to net income as determined under generally accepted accounting principles in the United States (GAAP), Exelon evaluates its operating performance using the measure of Adjusted (non-GAAP) Operating Earnings because management believes it represents earnings directly related to the ongoing operations of the business. Adjusted (non-GAAP) Operating Earnings exclude certain costs, expenses, gains and losses, and other specified items. This measure is intended to enhance an investor's overall understanding of period over period operating results and provide an indication of Exelon's baseline operating performance excluding items that are considered by management to be not directly related to the ongoing operations of the business. In addition, this measure 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. Adjusted (non-GAAP) Operating Earnings is not a presentation defined under GAAP and may not be comparable to other companies' presentation. Exelon has 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 (non-GAAP) Operating Earnings should not be deemed more useful than, a substitute for, or an alternative to the most comparable GAAP Net Income measures provided in this earnings release and attachments. This press release and earnings release attachments provide reconciliations of Adjusted (non-GAAP) Operating Earnings to the most directly comparable financial measures calculated and presented in accordance with GAAP, are posted on Exelon's website: www.exeloncorp.com, and have been furnished to the Securities and Exchange Commission on Form 8-K on Aug. 2, 2023.
