"The first quarter has put us firmly on the path to deliver within our full-year earnings guidance, through our unwavering commitment to safety, reliability and efficient execution of investments for our customers," said Exelon President and Chief Executive Officer Calvin Butler. “As Exelon celebrates our 25th year, our 20,000 employees continue to work hard to deliver value to our customers and positively impact the communities we serve.” “I’m pleased to announce first quarter 2025 adjusted operating earnings of $0.92 per share, keeping us on track to deliver within our full-year earnings guidance range of $2.64 - $2.74 per share,” said Exelon Chief Financial Officer Jeanne Jones. “In the first quarter of 2025, we also made substantial progress on our financing plan, executing half of our debt financing needs and over 60 percent of our annualized 2025 equity needs. Our balanced funding strategy enables us to invest in our local communities driving top quartile reliability while maintaining a sharp focus on cost efficiency." 1 First Quarter 2025 Exelon's GAAP net income for the first quarter of 2025 increased to $0.90 per share from $0.66 per share in the first quarter of 2024. Adjusted (non-GAAP) operating earnings for the first quarter of 2025 increased to $0.92 per share from $0.68 per share in the first quarter of 2024. For the reconciliations of GAAP net income to Adjusted (non-GAAP) operating earnings, refer to the tables beginning on page 4. The GAAP net income and Adjusted (non-GAAP) operating earnings in the first quarter of 2025 primarily reflect: • Higher utility earnings primarily due to distribution and transmission rate increases at ComEd and PHI, distribution rate increases at PECO and BGE, timing of distribution earnings at ComEd, less unfavorable weather and tax timing at PECO, and a higher return on regulatory assets primarily due to an increase in asset balances at ComEd. This was partially offset by lower transmission peak load at ComEd, and higher interest expense at PECO, BGE, and PHI. Utility rate increases are associated with updated recovery of incremental costs and investments to serve customers. Operating Company Results 1 ComEd ComEd's first quarter of 2025 GAAP net income increased to $302 million from $193 million in the first quarter of 2024. ComEd's Adjusted (non-GAAP) operating earnings for the first quarter of 2025 increased to $325 million from $219 million in the first quarter of 2024, primarily due to timing of distribution earnings, higher distribution and transmission rate base driven by incremental investments to serve customers, and higher return on regulatory assets primarily due to an increase in asset balances, partially offset by lower transmission peak load. Due to revenue decoupling, ComEd's distribution earnings are not intended to be affected by actual weather or customer usage patterns. PECO PECO’s first quarter of 2025 GAAP net income increased to $266 million from $149 million in the first quarter of 2024. PECO's Adjusted (non-GAAP) operating earnings for the first quarter of 2025 increased to $265 million from $149 million in the first quarter of 2024, primarily due to higher electric and gas distribution rates associated with updated recovery of investments to serve customers, normal weather compared to unfavorable weather in the prior period, and the timing of tax repairs deductions, partially offset by an increase in interest and credit loss expense. BGE BGE’s first quarter of 2025 GAAP net income decreased to $260 million from $264 million in the first quarter of 2024. BGE's Adjusted (non-GAAP) operating earnings for the first quarter of 2025 decreased to $260 million from $264 million in the first quarter of 2024, primarily due to an increase in interest expense offset by distribution rates. Due to revenue decoupling, BGE's distribution earnings are not intended to be affected by actual weather or customer usage patterns. ___________ 1 Exelon’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. 2 PHI PHI’s first quarter of 2025 GAAP net income increased to $194 million from $168 million in the first quarter of 2024. PHI’s Adjusted (non-GAAP) operating earnings for the first quarter of 2025 increased to $194 million from $168 million in the first quarter of 2024, primarily due to favorable distribution and transmission rates at Pepco and DPL driven by updated recovery of investments to serve customers, and favorable weather at DPL, partially offset by an increase in interest. Due to revenue decoupling, PHI's distribution earnings related to Pepco Maryland, DPL Maryland, Pepco District of Columbia, and ACE are not intended to be affected by actual weather or customer usage patterns.

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 4 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: https://investors.exeloncorp.com , and have been furnished to the Securities and Exchange Commission on Form 8-K on May 1, 2025.

Unless otherwise noted, the income tax impact of each reconciling item between GAAP net income 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 2025 and 2024 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) ComEd's distribution rate revenues increase or decrease as fully recoverable costs fluctuate. For other regulatory recovery mechanisms, including transmission formula rates and riders across the 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) For ComEd, reflects higher distribution and transmission rate base. For PECO, reflects increased distribution revenue primarily due to higher electric and gas rates. For BGE, reflects increased distribution revenue due to higher rates. For PHI, reflects increased distribution and transmission revenue primarily due to higher rates. (2) For ComEd, reflects increased electric distribution, transmission, and energy efficiency revenues due to higher fully recoverable costs and higher return on regulatory assets, partially offset by lower transmission peak load. For PECO, reflects increased energy efficiency revenues due to regulatory required programs, offset in Operating and maintenance expense. For PHI, reflects higher distribution and transmission revenues due to higher fully recoverable costs. (3) Represents Operating and maintenance expense, excluding pension and non-pension postretirement benefits. For ComEd, reflects a decrease in contracting costs. For PECO, primarily reflects increased credit loss expense and program costs related to regulatory required programs, offset in Other energy delivery. For BGE, reflects increased contracting costs. For PHI, reflects an increase in contracting costs and credit loss expense. For Corporate, primarily reflects a decrease in Operating and maintenance expense with an offsetting decrease in other income for an absence of costs billed to Constellation for services provided by Exelon through the TSA. (4) Reflects ongoing capital expenditures across all utilities. (5) For PECO, primarily reflects lower income tax expense due to timing of tax repairs deduction partially offset by an increase in interest expense. For BGE, primarily reflects an increase in interest expense. For PHI, primarily reflects an increase in interest expense and an increase in taxes other than income.
