GAAP Results of Operations. The following table sets forth Exelon's GAAP consolidated Net income attributable to common shareholders by Registrant for the three months ended March 31, 2025 compared to the same period in 2024. For additional information regarding the financial results for the three months ended March 31, 2025 and 2024, see the discussions of Results of Operations by Registrant.

(a)Other primarily includes eliminating and consolidating adjustments, Exelon’s corporate operations, shared service entities, and other financing and investment activities.

Three Months Ended March 31, 2025 Compared to Three Months Ended March 31, 2024. Net income attributable to common shareholders increased by $250 million and diluted earnings per average common share increased to $0.90 in 2025 from 0.66 in 2024 primarily due to:

•Timing of distribution earnings at ComEd;

•Favorable impacts of rate increases at ComEd, PECO, BGE and PHI;

•Normal weather at PECO compared to unfavorable weather in the prior period;

•Timing of income tax expense at PECO; and

•Higher return on regulatory assets at ComEd.

The increases were partially offset by:

•Higher interest expense at PECO, BGE and PHI; and

•Lower transmission peak load due to lower energy demand at ComEd.

Adjusted (non-GAAP) operating earnings. In addition to Net income, 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 information is intended to enhance an investor’s overall understanding of year-over-year operating results and provide an indication of Exelon’s baseline operating performance excluding items not considered by management to be directly related to the ongoing operations of the business. In addition, this information 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’ presentations or deemed more useful than the GAAP information provided elsewhere in this report.

The following table provides a reconciliation between GAAP Net income attributable to common shareholders and Adjusted (non-GAAP) operating earnings for the three months ended March 31, 2025 compared to the same period in 2024:
