Exhibit 99.1 News Release Contact: James Gherardi Corporate Communications 312-394-7417 Andrew Plenge Investor Relations 779-231-0017 EXELON REPORTS SECOND QUARTER 2025 RESULTS Earnings Release Highlights • GAAP net income of $0.39 per share and Adjusted (non-GAAP) operating earnings of $0.39 per share for the second quarter of 2025 • Affirming full year 2025 Adjusted (non-GAAP) operating earnings guidance range of $2.64-$2.74 per share • Reaffirming operating EPS compounded annual growth of 5-7% from 2024 to 2028 • All utilities sustained top quartile or better performance in reliability and BGE, PECO, and PHI sustained top quartile or better performance in gas odor response • Executed ~80% of planned debt financings and continued strong progress on equity financing, having now priced 100% of $700 million annualized equity financing need for 2025 and ~22% for 2026 CHICAGO (Jul 31, 2025) — Exelon Corporation (Nasdaq: EXC) today reported its financial results for the second quarter of 2025. "Exelon’s second-quarter performance reflects our disciplined execution across all fronts," said Exelon President and Chief Executive Officer Calvin Butler. "We remain focused on delivering long-term value through operational excellence, customer affordability solutions and a balanced investment strategy that supports grid modernization and energy security. As we reaffirm our financial guidance, we are confident in our ability to meet the evolving needs of our customers and communities while advancing a cleaner, more resilient energy future." “I’m pleased to announce we delivered second quarter 2025 adjusted operating earnings of $0.39 per share, overcoming an active start to the summer storm season, including one of the largest in recent history at PECO with peak outages over 325,000 customers," said Exelon Chief Financial Officer Jeanne Jones. "We remain on track to deliver within our full-year earnings guidance range of $2.64 - $2.74 per share, and our performance underscores our ability to deliver strong financial and operational results while keeping our customers front and center.” 1 Second Quarter 2025 Exelon's GAAP net income for the second quarter of 2025 decreased to $0.39 per share from $0.45 per share in the second quarter of 2024. Adjusted (non-GAAP) operating earnings for the second quarter of 2025 decreased to $0.39 per share from $0.47 per share in the second 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 second quarter of 2025 primarily reflect: • Lower utility earnings primarily due to timing of distribution earnings at ComEd, increased storm costs at PECO, lower impacts of the Maryland multi-year plan reconciliations at PHI, lower transmission peak load at ComEd, and higher credit loss and interest expense at PHI. This was partially offset by distribution rate increases at PECO and BGE, distribution and transmission rate increases at ComEd and PHI, and a higher return on regulatory assets at ComEd. • Higher costs at Exelon holding company due to the Customer Relief Fund contribution and higher interest expense. The Customer Relief Fund is a one-time charitable contribution to trusted local nonprofits to assist low and middle-income customers with higher energy costs. Operating Company Results 1 ComEd ComEd's second quarter of 2025 GAAP net income decreased to $228 million from $270 million in the second quarter of 2024. ComEd's Adjusted (non-GAAP) operating earnings for the second quarter of 2025 decreased to $228 million from $285 million in the second quarter of 2024, primarily due to the timing of distribution earnings and lower transmission peak load, partially offset by 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. 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 2025 GAAP net income increased to $136 million from $90 million in the second quarter of 2024. PECO's Adjusted (non-GAAP) operating earnings for the second quarter of 2025 increased to $136 million from $93 million in the second quarter of 2024, primarily due to higher electric and gas distribution rates associated with updated recovery of investments to serve customers, partially offset by an increase in storm costs. ___________ 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 BGE BGE’s second quarter of 2025 GAAP net income increased to $55 million from $45 million in the second quarter of 2024. BGE's Adjusted (non-GAAP) operating earnings for the second quarter of 2025 increased to $55 million from $45 million in the second quarter of 2024, primarily due to distribution rates associated with updated recovery of investments to serve customers, partially offset by the derecognition of regulatory assets and liabilities as a result of the Next Generation Energy Act. 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 2025 GAAP net income decreased to $143 million from $158 million in the second quarter of 2024. PHI’s Adjusted (non-GAAP) operating earnings for the second quarter of 2025 decreased to $144 million from $162 million in the second quarter of 2024, primarily due to lower impacts of the Maryland multi-year plans reconciliations, increases in credit loss and interest expense, and storm costs at Pepco, partially offset by favorable distribution and transmission rates driven by updated recovery of investments to serve customers. 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.

The dividend is payable on September 15, 2025, to Exelon's shareholders of record as of the close of business on August 11, 2025. • Rate Case Developments: ◦ There were no rate case developments in the second quarter. • Financing Activities: ◦ On May 16, 2025, BGE issued $650 million of its 5.45% Notes due June 1, 2035.

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) 4 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: https://investors.exeloncorp.com , and have been furnished to the Securities and Exchange Commission on Form 8-K on July 31, 2025.
