Important note to investors regarding operating, reported earnings Dominion Energy uses operating earnings (non-GAAP) as the primary performance measurement of its results for public communications with analysts and investors. Operating earnings are defined as reported earnings adjusted for certain items. Dominion Energy also uses operating earnings internally for budgeting, for reporting to the Board of Directors, for the company’s incentive compensation plans, and for its targeted dividend payouts and other purposes. Dominion Energy management believes operating earnings provide a more meaningful representation of the company’s fundamental earnings power. In providing its operating earnings guidance, the company notes that there could be differences between expected reported earnings and estimated operating earnings for matters such as, but not limited to, the mark-to-market impact of economic hedging activities, gains and losses on nuclear decommissioning trust funds, market-related impacts on pension and other postretirement benefit plans, acquisitions, divestitures, or extreme weather events and other natural disasters. At this time, Dominion Energy management is not able to estimate the aggregate impact of these items on future period reported earnings. Accordingly, Dominion Energy is not able to provide a corresponding GAAP equivalent for its operating earnings guidance.
