The information in this presentation was prepared as of November 4, 2024. Dominion Energy undertakes no obligation to update any forward-looking information statement to reflect developments after the statement is made. Projections or forecasts shown in this document are based on the assumptions listed in this document and are subject to change at any time. This presentation shall not constitute an offer to sell or the solicitation of an offer to buy securities. Any offers to sell or solicitations of offers to buy securities will be made in accordance with the requirements of the Securities Act of 1933, as amended. This presentation has been prepared primarily for security analysts and investors in the hope that it will serve as a convenient and useful reference document. The format of this document may change in the future as we continue to try to meet the needs of security analysts and investors. This document is not intended for use in connection with any sale, offer to sell or solicitation of any offer to buy securities. This presentation includes certain financial measures that have not been prepared in accordance with U.S. generally accepted accounting principles (GAAP). In providing projections, estimates or guidance of operating earnings per share guidance (non-GAAP) and FFO to debt (non-GAAP), the company notes that there could be differences between such non-GAAP financial measures and the GAAP equivalents of reported net income per share and reported net cash provided by operating activities to reported long-term debt, short-term debt, supplement credit facility borrowings and securities due within one year, respectively. Reconciliations of such non-GAAP measures to their GAAP equivalents are not provided, because the company cannot, without unreasonable effort, estimate or predict with certainty various components of net income, net cash provided by operating activities, long-term debt, short-term debt, supplemental credit facility borrowings or securities due within one year.
