Dominion Energy announces 2024 financial results

RICHMOND, Va. – Dominion Energy, Inc. (NYSE: D), today announced unaudited net income determined in accordance with Generally Accepted Accounting Principles (GAAP, or reported earnings) for the three months ended Dec. 31, 2024, of $145 million ($0.15 per share) compared with net income of $331 million ($0.37 per share) for the same period in 2023, with net income of $2.1 billion ($2.44 per share) for the 12 months ended Dec. 31, 2024, compared with net income of $2.0 billion ($2.33 per share) for the same period in 2023.

“We delivered 2024 operating earnings per share in the top half of our guidance range despite worse-than-normal weather in our regulated service areas. In addition, we continued to successfully provide the reliable, affordable, and increasingly clean energy that powers our customers every day while achieving near-record employee safety performance,” said Bob Blue, chair, president and chief executive officer of Dominion Energy.

Operating earnings (non-GAAP) for the three months ended Dec. 31, 2024, were $504 million ($0.58 per share), compared to operating earnings of $260 million ($0.29 per share) for the same period in 2023. Operating earnings for the 12 months ended Dec. 31, 2024, were $2.4 billion ($2.77 per share) compared with operating earnings of $1.7 billion ($1.95 per share) for the same period in 2023.

Differences between GAAP and operating earnings for the period include gains and losses on nuclear decommissioning trust funds, mark-to-market impact of economic hedging activities, a net benefit from discontinued operations primarily associated with the sale of gas distribution operations, and other adjustments. Details of operating earnings as compared to prior periods, business segment results and detailed descriptions of items included in reported earnings but excluded from operating earnings can be found on Schedules 1, 2, 3 and 4 of this release.

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.
