3 Non-GAAP Financial Measures Exelon reports its financial results in accordance with accounting principles generally accepted in the United States (GAAP). Exelon supplements the reporting of financial information determined in accordance with GAAP with certain non-GAAP financial measures, including: • Adjusted operating earnings (operating EPS) excludes certain costs, expenses, gains, and losses and other specified items that are considered by management to be not directly related to the ongoing operations of the business as described in Reconciliation of Non-GAAP Measures. • Adjusted operating and maintenance (O&M) expense excludes regulatory operating and maintenance costs for the utility businesses and certain excluded items. • Operating ROE is calculated using operating net income divided by average equity for the period. The operating income reflects all lines of business for the utility business (gas distribution, electric transmission, and electric distribution). • Adjusted cash from operations primarily includes cash flows from operating activities adjusted for common dividends and change in cash on hand. • S&P FFO/Debt and Moody’s CFO (Pre-WC)/Debt are calculated using the respective S&P and Moody’s methodologies described in Reconciliation of Non-GAAP Measures. Due to the forward-looking nature of some forecasted non-GAAP measures, information to reconcile the forecasted adjusted (non-GAAP) measures to the most directly comparable GAAP measure may not be currently available, therefore, management is unable to reconcile these measures. This information is intended to enhance an investor’s overall understanding of period over period financial results and provide an indication of Exelon’s baseline operating performance by 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. These non-GAAP financial measures are not a presentation defined under GAAP and may not be comparable to other companies’ presentations. Exelon has provided these non- GAAP financial measures as supplemental information and in addition to the financial measures that are calculated and presented in accordance with GAAP. These non-GAAP measures should not be deemed more useful than, a substitute for, or an alternative to the most comparable GAAP measures provided in the materials presented. Non-GAAP financial measures are identified by the phrase “non-GAAP” or an asterisk (*). Reconciliations of these non-GAAP measures to the most comparable GAAP measures are provided in this presentation in Reconciliation of Non-GAAP Measures.
