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

"Our team of 19,000 plus employees have entered this first full year of operations after the separation excited to lead the energy transformation, and it shows in our results," said Exelon President and CEO Calvin Butler. "In addition to strong financial performance, all four of our utilities achieved best-on-record reliability. These results are a testament to our team's hard work, smart investment, and commitment to financial and operational excellence. As we continue to execute on our financial, operational and regulatory objectives in 2023, we continue to keep our customers at the forefront of everything we do."

"2023 is off to a strong start, delivering Adjusted (non-GAAP) Operating Earnings of $0.70 per share, $0.06 ahead of results in the first quarter of 2022, driven by increased revenues associated with the investments we are making on behalf of customers," said Exelon Executive Vice President and CFO Jeanne Jones. "With most of our planned debt financing activity complete for the year and all but one of our planned rate cases now filed, we are well on our way to executing on the plan laid out at the beginning of the year. We reaffirm our full-year Adjusted (non-GAAP) Operating Earnings guidance range of $2.30 to $2.42 per share."

First Quarter 2023

Exelon's GAAP Net Income from Continuing Operations for the first quarter of 2023 increased to $0.67 per share from $0.49 GAAP Net Income from Continuing Operations per share in the first quarter of 2022. Adjusted (non-GAAP) Operating Earnings for the first quarter of 2023 increased to $0.70 per share from $0.64 per share in the first 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 5.

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

Higher 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 impacts of higher rate base, rate increases at PECO, BGE, and PHI, and carrying costs related to the carbon mitigation credit (CMC) regulatory assets at ComEd. This was partially offset by unfavorable weather at PECO and PHI, higher depreciation expense at PECO, higher credit loss expense at PECO, and higher interest expense at BGE.
Lower costs at the Exelon holding company due to certain BSC costs that were historically allocated to Constellation Energy Generation, LLC (Generation) but are presented as part of continuing operations in Exelon's results in the first quarter of 2022 as these costs do not qualify as expenses of the discontinued operations per the accounting rules. This was partially offset by higher interest expense.

Operating Company Results¹

ComEd

ComEd's first quarter of 2023 GAAP Net Income increased to $241 million from $188 million in the first quarter of 2022. ComEd's Adjusted (non-GAAP) Operating Earnings for the first quarter of 2023 increased to $251 million from $193 million in the first 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 assets. Due to revenue decoupling, ComEd's distribution earnings are not affected by actual weather or customer usage patterns.

___________

¹Exelon's four business units include ComEd, which consists of electricity transmission and distribution operations in northern Illinois; PECO, which consists of electricity transmission and distribution operations and retail natural gas distribution operations in southeastern Pennsylvania; BGE, which consists of electricity transmission and distribution operations and retail natural gas distribution operations in central Maryland; and PHI, which consists of electricity transmission and distribution operations in the District of Columbia and portions of Maryland, Delaware, and New Jersey and retail natural gas distribution operations in northern Delaware.

PECO

PECO's first quarter of 2023 GAAP Net Income decreased to $166 million from $206 million in the first quarter of 2022. PECO's Adjusted (non-GAAP) Operating Earnings for the first quarter of 2023 decreased to $166 million from $208 million in the first quarter of 2022, primarily due to unfavorable weather, an increase in credit loss expense and depreciation expense, partially offset by gas distribution rate increases.

BGE

BGE's first quarter of 2023 GAAP Net Income increased to $200 million from $198 million in the first quarter of 2022. BGE's Adjusted (non-GAAP) Operating Earnings for the first quarter of 2023 decreased to $199 million from $200 million in the first quarter of 2022, primarily due to an increase in interest expense, offset by favorable impacts of the multi-year plans. Due to revenue decoupling, BGE's distribution earnings are not affected by actual weather or customer usage patterns.

PHI

PHI's first quarter of 2023 GAAP Net Income increased to $155 million from $130 million in the first quarter of 2022. PHI's Adjusted (non-GAAP) Operating Earnings for the first quarter of 2023 increased to $173 million from $136 million in the first quarter of 2022, primarily due to distribution and transmission rate increases, partially offset by unfavorable weather. 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 First Quarter Highlights

ACE New Jersey Electric Base Rate Case: On February 15, 2023, ACE filed an application with the NJBPU to increase its annual electric distribution rates by $105 million, reflecting a requested ROE of 10.50%. ACE currently expects a decision in the first quarter of 2024, but cannot predict if the NJBPU will approve the application as filed. ACE intends to put rates into effect on November 17, 2023, subject to refund.
BGE Maryland Electric and Natural Gas Base Rate Case: On February 17, 2023, BGE filed an application for a three-year cumulative multi-year plan for 2024 through 2026 with the MDPSC. Inclusive of the proposed acceleration of remaining electric tax benefits in 2024 and 2025, and remaining gas tax benefits in 2024, BGE requested total electric revenue requirement increases of $85 million, $103 million, and $125 million in 2024, 2025, and 2026, respectively, and natural gas revenue requirement increases of $158 million, $77 million, and $54 million in 2024, 2025, and 2026, respectively. The electric and gas revenue requirement increases reflect a requested ROE of 10.4%. Requested revenue requirement increases will be used to recover capital investments designed to increase the resilience of the electric and gas distribution systems and support Maryland's climate and regulatory initiatives. BGE currently expects a decision in the fourth quarter of 2023, but cannot predict if the MDPSC will approve the application as filed. The 2021 and 2022 reconciliation amounts are not included in the requested revenue requirement increase, as BGE is proposing that these amounts be recovered through the separate electric and gas riders in 2024. The 2021 reconciliation amounts are $11 million and $7 million for electric and gas, respectively, and the 2022 reconciliation amounts are $44 million and $15 million for electric and gas, respectively.
Pepco District of Columbia Electric Base Rate Case: On April 13, 2023, Pepco filed an application for a three-year cumulative multi-year plan for 2024 through 2026 with the DCPSC. Pepco requested total electric revenue requirement increases of $117 million, $37 million, and $37 million in 2024, 2025, and 2026, respectively. The electric revenue requirement increases reflect a requested ROE of 10.50%. Requested revenue requirement increases will be used to recover capital investments designed to advance system-readiness and support the District of Columbia's climate and clean energy goals. Pepco currently expects a decision in the first quarter of 2024, but cannot predict if the DCPSC will approve the application as filed.
ComEd Distribution Formula Rate Reconciliation: On April 21, 2023, ComEd filed its proposed Delivery Reconciliation Amount of $247 million under Rider Delivery Service Pricing Reconciliation which allows for the reconciliation of the revenue requirement in effect in the final years in which formula rates are determined and until such time as new rates are established under ComEd's approved MRP. The 2023 filing reconciles the delivery service rates in effect in 2022 with the actual delivery service costs incurred in 2022. Final order is expected by December 2023, and the reconciliation amount will be in customer rates beginning January 1, 2024.

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 May 3, 2023.

Note:
Amounts may not sum due to rounding.
Unless otherwise noted, the income tax impact of each reconciling item between GAAP Net Income from Continuing Operations and Adjusted (non-GAAP) Operating Earnings is based on the marginal statutory federal and state income tax rates for each Registrant, taking into account whether the income or expense item is taxable or deductible, respectively, in whole or in part. For all items, the marginal statutory income tax rates for 2023 and 2022 ranged from 24.0% to 29.0%.

(a)		Other primarily includes eliminating and consolidating adjustments, Exelon's corporate operations, shared service entities, and other financing and investment activities.
(b)		For ComEd, BGE, Pepco, DPL Maryland, and ACE, customer rates are adjusted to eliminate the impacts of weather and customer usage on distribution volumes.
(c)		For regulatory recovery mechanisms, including ComEd's distribution formula rate and energy efficiency formula, ComEd, PECO, BGE, and PHI utilities transmission formula rates, and riders across all utilities, revenues increase and decrease i) as fully recoverable costs fluctuate (with no impact on net earnings), and ii) pursuant to changes in rate base, capital structure and ROE (which impact net earnings).
(1)		Reflects costs related to a multi-year ERP system implementation, which are recorded in Operating and maintenance expense.
(2)		Represents costs related to the separation primarily comprised of system-related costs, third-party costs paid to advisors, consultants, lawyers, and other experts assisting in the separation, and employee-related severance costs, which are recorded in Operating and maintenance expense.
(3)		In connection with the separation, Exelon recorded an income tax expense primarily due to the long-term marginal state income tax rate change, the recognition of valuation allowances against the net deferred tax assets positions for certain standalone state filing jurisdictions, and nondeductible transaction costs.
(4)		For ComEd, reflects increased electric distribution revenues due to higher allowed electric distribution ROE driven by an increase in treasury rates and higher rate base. For PECO, reflects increased revenue primarily due to distribution rate increases. For BGE, reflects increased revenue due to distribution rate increases. For PHI, reflects increased revenue primarily due to distribution and transmission rate increases.
(5)		For ComEd, reflects increased electric distribution, transmission, and energy efficiency revenues due to higher fully recoverable costs and also reflects carrying costs related to the CMC regulatory assets. For PHI, includes the regulatory asset amortization of the ACE Purchase Power Agreement termination obligation recorded in the first quarter of 2022, which is fully recoverable.
(6)		Represents Operating and maintenance expense, excluding pension and non-pension postretirement benefits. For PECO, reflects increased credit loss expense. For PHI, includes decreased storm costs. For Corporate, primarily reflects two offsetting items: 1) lower BSC costs that were historically allocated to Generation but are presented as part of continuing operations in Exelon's results as these costs do not qualify as expenses of the discontinued operations per the accounting rules (YTD Q1 2023 includes no costs compared to one month of costs for the period prior to the separation for YTD Q1 2022) and 2) a decrease in Operating and maintenance expense with an offsetting decrease in other income for costs billed to Constellation for services provided by Exelon through the Transition Services Agreement (TSA).
(7)		Reflects ongoing capital expenditures across all utilities and higher depreciation rates effective January 2023 for ComEd. For BGE, also reflects decreased amortization for regulatory required programs. For PHI, includes the regulatory asset amortization of the ACE Purchase Power Agreement termination obligation recorded in the first quarter of 2022, which is fully recoverable in Other Energy Delivery.
(8)		For Corporate, Other primarily reflects a decrease in other income for costs billed to Constellation for services provided by Exelon through the TSA with an offsetting decrease in Operating and maintenance expense.
(9)		Reflects the impact on earnings per share due to the increase in Exelon's average diluted common shares outstanding as a result of the August 2022 common stock issuance.
