Non-GAAP Financial Matters EEI Financial Conference – Published November 8, 202111 This presentation contains references to non-GAAP financial measures including, among others, Operating earnings (loss), Operating earnings (loss) per share (EPS), Operating earnings (loss) per share (EPS) by segment, Free Cash Flow (FCF), Funds from Operations (FFO) and Adjusted Cash from Operations. Generally, a non-GAAP financial measure is a numerical measure of a company’s historical or future financial performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with accounting principles generally accepted in the United States (GAAP). Operating earnings (loss), Operating earnings (loss) per share, Operating earnings (loss) per share by segment, FCF and Adjusted Cash from Operations are not calculated in accordance with GAAP to the extent they exclude the impact of “special items.” Special items represent charges incurred or benefits realized that management believes are not indicative of, or may obscure trends useful in evaluating the company’s ongoing core activities and results of operations or otherwise warrant separate classification. Special items are not necessarily non-recurring. FE Management cannot estimate on a forward-looking basis the impact of these items in the context of Operating earnings per share guidance for 2022 and future annual projected earnings growth because these items, which could be significant are difficult to predict and may be highly variable. Consequently, the Company is unable to reconcile Operating earnings per share guidance for 2022 and future annual projected earnings growth to a GAAP measure without unreasonable effort. Basic (GAAP) EPS and Operating EPS and Basic (GAAP) EPS and Operating EPS for each segment are calculated by dividing Operating earnings (loss), which excludes special items as discussed above, by 545 million shares for 2021 and 573 million shares for 2022. Management uses non-GAAP financial measures such as Operating earnings (loss), Operating earnings (loss) per share, FCF, and Adjusted Cash from Operations to evaluate the Company’s performance and manage its operations and frequently references these non-GAAP financial measures in its decision-making, using them to facilitate historical and ongoing performance comparisons. Additionally, management uses Operating earnings (loss) per share by segment to further evaluate the Company’s performance by segment and references this non-GAAP financial measure in its decision-making. Management believes that the non-GAAP financial measures of Operating earnings (loss), Operating earnings (loss) per share and Operating earnings (loss) per share by segment, Free Cash Flow, and Adjusted Cash from Operations provide consistent and comparable measures of performance of its businesses on an ongoing basis. Management also believes that such measures are useful to shareholders and other interested parties to understand performance trends and evaluate the Company against its peer group by presenting period-over-period operating results without the effect of certain charges or benefits that may not be consistent or comparable across periods or across the Company’s peer group. All of these non-GAAP financial measures are intended to complement, and are not considered as alternatives to, the most directly comparable GAAP financial measures. Also, the non-GAAP financial measures may not be comparable to similarly titled measures used by other entities. Pursuant to the requirements of Regulation G, FE has provided, where possible without unreasonable effort, quantitative reconciliations within this presentation of the non-GAAP financial measures to the most directly comparable GAAP financial measures.
