Equity Method Investments Dominion Energy recorded equity earnings on its investments of less than $1 million and $2 million for the three months ended March 31, 2024 and 2023, respectively, in other income (expense) in its Consolidated Statements of Income. In addition, Dominion Energy recorded equity earnings (losses) of $(10) million and $76 million for the three months ended March 31, 2024 and 2023, respectively, in discontinued operations, including amounts related to its investments in Cove Point and Atlantic Coast Pipeline discussed below. Dominion Energy received distributions of $131 million and $85 million for the three months ended March 31, 2024 and 2023, respectively. Dominion Energy made contributions of $3 million and $10 million for the three months ended March 31, 2024 and 2023, respectively. At March 31, 2024 and December 31, 2023, the net difference between the carrying amount of Dominion Energy’s investments and its share of underlying equity in net assets was $13 million and $18 million, respectively. At March 31, 2024, these differences are primarily comprised of $9 million of equity method goodwill that is not being amortized and $2 million attributable to capitalized interest. At December 31, 2023, these differences are primarily comprised of $9 million of equity method goodwill that is not being amortized and $3 million attributable to capitalized interest. Cove Point See Note 9 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2023 for a discussion of the sale of Dominion Energy’s remaining interest in Cove Point to BHE, which closed in September 2023. Dominion Energy recorded distributions from Cove Point of $83 million for the three months ended March 31, 2023. Amounts presented within discontinued operations within Dominion Energy’s Consolidated Statements of Income related to Cove Point for the three months ended March 31, 2023 were $76 million for earnings on equity method investees, $62 million of interest expense and $3 million of income tax expense. Atlantic Coast Pipeline A description of Dominion Energy’s investment in Atlantic Coast Pipeline, including events that led to the cancellation of the Atlantic Coast Pipeline Project in July 2020, is included in Note 9 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2023. Dominion Energy recorded equity losses related to Atlantic Coast Pipeline of $11 million and $1 million for the three months ended March 31, 2024 and 2023, respectively, in discontinued operations. At March 31, 2024 and December 31, 2023, Dominion Energy has recorded a liability of $14 million and $4 million, respectively, in other current liabilities in its Consolidated Balance Sheets as a result of its share of equity losses exceeding its investment which reflects Dominion Energy’s obligations on behalf of Atlantic Coast Pipeline related to its AROs. Dominion Energy expects it could incur additional losses from Atlantic Coast Pipeline as it completes wind-down activities. While Dominion Energy is unable to precisely estimate the amounts to be incurred by Atlantic Coast Pipeline, the portion of such amounts attributable to Dominion Energy is not expected to be material to Dominion Energy’s results of operations, financial position or statement of cash flows. Dominion Privatization In February 2024, Dominion Energy received a distribution of $126 million from Dominion Privatization, which was accounted for as a return of an investment.
