(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, 2024 Compared to Three Months Ended March 31, 2023. Net income attributable to common shareholders decreased by $11 million and diluted earnings per average common share decreased to $0.66 in 2024 from $0.67 in 2023 primarily due to:

•Higher interest expense at PECO, PHI, and Exelon Corporate;

•Higher storm costs at PECO and BGE;

•Lower electric distribution earnings from lower ROE and the absence of a return on the pension asset at ComEd; and

•Lower carrying costs related to the CMC regulatory assets at ComEd.

The decreases were partially offset by:

•The favorable impacts of rate increases at BGE and PHI; and

•Less unfavorable weather impacts at PECO.

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 that are considered by management to be not 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.
