As energy demand continues to grow, we remain focused on advancing solutions through The Exelon Promise that strengthen reliability, protect customers, keep bills as low as possible, and create long-term value for the communities we serve. From grid modernization to practical solutions such as storage and virtual power plants, we are helping meet growing energy demand and enabling a more affordable and reliable grid.” “Exelon delivered second quarter 2026 adjusted operating earnings of $0.43 per share, in line with the expectations we discussed on our first quarter call,” said Exelon Chief Financial Officer Jeanne Jones. “Through the first half of the year, we remain on track to deliver full-year operating earnings of $2.81 to $2.91 per share and annualized earnings growth near the top end of 5% to 7% from 2025 through 2029. With substantial progress on our financing plan, we are well positioned to fund customer-focused 1 investments across our utilities and advance additional solutions, such as storage, that support affordability, reliability and resource adequacy.” Second Quarter 2026 Exelon's GAAP net income for the second quarter of 2026 remained relatively consistent with the prior period at $0.39 per share. Adjusted (non-GAAP) operating earnings for the second quarter of 2026 increased to $0.43 per share from $0.39 per share in the second quarter of 2025. 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 second quarter of 2026 primarily reflect: • Higher utility earnings primarily due to distribution and transmission rates at ComEd and PHI, distribution rates at BGE, absence of customer surcharge credits at PECO, higher allowance for funds used during construction (AFUDC) at ComEd, and favorable weather at PECO. This was partially offset by higher depreciation at PECO and PHI, higher credit loss expense at BGE, and higher interest expense and income taxes at PECO. Note that rate increases are associated with updated recovery rates for costs and investments to serve customers. • Lower costs at the Exelon holding company due to the lack of Customer Relief Fund contribution and lower income taxes were offset by higher interest expense. Operating Company Results 1 ComEd ComEd's second quarter of 2026 GAAP net income increased to $249 million from $228 million in the second quarter of 2025. ComEd's Adjusted (non-GAAP) operating earnings for the second quarter of 2026 increased to $249 million from $228 million in the second quarter of 2025, primarily due to an increase in higher distribution and transmission rate base driven by incremental investments to serve customers, driving top quartile reliability and avoiding outage costs, and higher AFUDC. Due to revenue decoupling, ComEd's distribution earnings are not intended to be affected by actual weather or customer usage patterns. PECO PECO’s second quarter of 2026 GAAP net income decreased to $119 million from $136 million in the second quarter of 2025. PECO's Adjusted (non-GAAP) operating earnings for the second quarter of 2026 decreased to $130 million from $136 million in the second quarter of 2025, primarily due to an increase in depreciation and interest expense, and higher income taxes due to tax repairs, a portion of which is timing, partially offset by absence of surcharge credits to customers and favorable weather. ___________ 1 Exelon’s four business units include ComEd, which consists of electricity transmission and distribution operations in northern Illinois (and transmission in a small portion of northwestern Indiana); 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 BGE BGE’s second quarter of 2026 GAAP net income remained relatively consistent with the prior period at $55 million in the second quarter of 2025. BGE's Adjusted (non-GAAP) operating earnings for the second quarter of 2026 increased to $70 million from $55 million in the second quarter of 2025, primarily due to approved distribution rates associated with updated recovery of investments to serve customers, driving top quartile reliability and avoiding outage costs, partially offset by an increase in credit loss expense. Due to revenue decoupling, BGE's distribution earnings are not intended to be affected by actual weather or customer usage patterns. PHI PHI’s second quarter of 2026 GAAP net income decreased to $109 million from $143 million in the second quarter of 2025. PHI’s Adjusted (non-GAAP) operating earnings for the second quarter of 2026 decreased to $126 million from $144 million in the second quarter of 2025, primarily due to an increase in depreciation, partially offset by approved distribution and transmission rates driven by updated recovery of investments to serve customers, driving top quartile reliability and avoiding outage costs. 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 operations of the business. Adjusted (non-GAAP) operating earnings exclude certain costs, expenses, 4 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: investors.exeloncorp.com , and have been furnished to the Securities and Exchange Commission on Form 8-K on July 30, 2026.
