Section 8 - Other Events
Item 8.01. Other Events

As previously disclosed in the Form 10-K filed on February 24, 2021, extreme cold weather conditions in February 2021 resulted in outages at the Texas-based generating assets of Exelon Generation Company, LLC (Generation) within the Electric Reliability Council of Texas (ERCOT).

On April 28, 2021, Exelon Corporation (Exelon) affirmed the range for full year 2021 Adjusted (non-GAAP) Operating Earnings guidance of $2.60 - $3.00 per share. For the first quarter of 2021, Exelon estimates a GAAP Net Loss of $(0.30) per share and an Adjusted (non-GAAP) Operating Loss of $(0.06) per share.

Exelon and Generation are increasing the full year estimated loss from the February market and weather event by $150 million pre-tax or $110 million after-tax, compared to the February 24, 2021 disclosure. The estimated loss for the full year 2021 is approximately $900 million to $1.1 billion pre-tax or $670 million to $820 million after-tax. The estimated full year impact includes updated load meter data and ERCOT default payments that differed from our February 24th estimate. The ultimate impact to Exelon’s and Generation’s earnings may be affected by a number of factors, including final settlement data, the impacts of customer and counterparty credit losses, any state or federal solutions to address the financial challenges caused by the event, and related litigation and contract disputes.
Exelon expects to offset between $550 million and $650 million pre-tax or $410 million and $490 million after-tax of this loss impact for the full year 2021, primarily at Generation through a combination of enhanced revenue opportunities, deferral of selected non-essential maintenance, and primarily one-time cost savings.

Exelon and Generation estimate the first quarter 2021 impact from the weather event to be a loss of approximately $1.2 billion pre-tax or $880 million after-tax. The first quarter estimated impact includes certain charges associated with the natural gas business that may be reduced through waivers and/or recoveries from customers. Therefore, such charges are not included in the estimated full year earnings impact.

Non-GAAP Financial Measures

Reconciliation of the GAAP Net Loss to Adjusted (non-GAAP) Operating Loss will be included in the Form 8-K to be filed on May 5, 2021 when Exelon announces its results for the quarter ended March 31, 2021. The outlook for 2021 Adjusted (non-GAAP) Operating Earnings for Exelon excludes the following items that would be included in a GAAP calculation:

•    Mark-to-market adjustments from economic hedging activities;
•    Unrealized gains and losses from nuclear decommissioning trust funds to the extent not offset by contractual accounting as described in the notes to the consolidated financial statements;
•    Certain costs related to plant retirements and divestitures;
•    Certain costs incurred to achieve cost management program savings;
•    Direct costs related to the novel coronavirus (COVID-19) pandemic;
•    Certain acquisition-related costs;
•    Costs related to a multi-year Enterprise Resource Program (ERP) system implementation;
•    Costs related to the planned separation;
•    Other items not directly related to the ongoing operations of the business; and
•    Generation's noncontrolling interest related to exclusion items.

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, 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.
