FirstEnergy’s Press Release and 3Q 2023 Strategic and Financial Highlights, which are attached as Exhibits 99.1 and 99.2, respectively, hereto and incorporated herein by reference, contain non-GAAP financial measures. Pursuant to the requirements of Regulation G and Item 10(e)(i) of Regulation S-K, FirstEnergy has provided quantitative reconciliations within the Press Release and 3Q 2023 Strategic and Financial Highlights of certain non-GAAP financial measures to the most directly comparable financial measures calculated and presented in accordance with accounting principles generally accepted in the United States (GAAP).

Item 2.02 Results of Operations and Financial Condition

On July 22, 2021, FirstEnergy Corp. (FirstEnergy or Company) issued two public documents which, among other things: provide results for the three months and six months ended June 30, 2021; update its full year 2021 GAAP earnings forecast; affirm its operating (non-GAAP) earnings guidance for the full year 2021; and provide its third quarter 2021 GAAP and operating (non-GAAP) earnings forecast. FirstEnergy’s Press Release and 2Q 2021 Strategic and Financial Highlights, which are attached as Exhibits 99.1 and 99.2, respectively, hereto and incorporated herein by reference, contain non-GAAP financial measures. Pursuant to the requirements of Regulation G and Item 10(e)(i) of Regulation S-K, FirstEnergy has provided quantitative reconciliations within the Press Release and 2Q 2021 Strategic and Financial Highlights of the non-GAAP financial measures to the most directly comparable financial measures calculated and presented in accordance with accounting principles generally accepted in the United States (GAAP). The information set forth in and incorporated into this Item 2.02 of this Current Report on Form 8-K is being furnished pursuant to Item 2.02 of Form 8-K and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference into any of the Company’s filings under the Securities Act of 1933 or the Securities Exchange Act of 1934, whether made before or after the date hereof and regardless of any general incorporation language in such filings, except to the extent expressly set forth by specific reference in such a filing. The attached Press Release and 2Q 2021 Strategic and Financial Highlights contain references to non-GAAP financial measures including, among others, Operating earnings (loss); Operating earnings (loss) per share; Operating earnings (loss) per share on a segment basis 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 GAAP. Operating earnings (loss), Operating earnings (loss) per share, Operating earnings (loss) per share by segment 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. The Company’s management cannot estimate on a forward-looking basis the impact of these items in the context of Operating earnings (loss) per share because these items, which could be significant, are difficult to predic
