(1) Dominion Energy’s Consolidated Balance Sheets include a liability associated with its investment in Atlantic Coast Pipeline of $7 million and $4 million at December 31, 2024 and 2023, respectively, presented in other current liabilities. See discussion below for additional information. (2) Dominion Energy’s Consolidated Balance Sheets includes balances presented in assets held for sale of $43 million for December 31, 2023. Dominion Energy recorded equity earnings (losses) on its investments of $3 million, $(26) million and $21 million for the years ended December 31, 2024, 2023 and 2022, respectively, in other income (expense) in its Consolidated Statements of Income. In addition, Dominion Energy recorded equity earnings (losses) of $(12) million, $235 million and $271 million for the years ended December 31, 2024, 2023 and 2022, respectively, in discontinued operations including amounts related to its investments in Cove Point (through September 2023) and Atlantic Coast Pipeline discussed below. Dominion Energy received distributions from these investments of $140 million, $245 million and $355 million for the years ended December 31, 2024, 2023 and 2022, respectively. As of December 31, 2024 and 2023, the net difference between the carrying amount of Dominion Energy’s investments and its share of underlying equity in net assets was $5 million and $18 million, respectively. At December 31, 2024, this difference is 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 Prior to the completion of the sale to BHE in September 2023, Dominion held a 50% noncontrolling limited partnership interest in Cove Point which was accounted for as an equity method investment as Dominion Energy had the ability to exercise significant influence over, but not control, Cove Point. Dominion Energy recorded distributions from Cove Point of $227 million and $344 million for the years ended December 31, 2023 and 2022, respectively. Dominion Energy made no contributions to Cove Point for the years ended December 31, 2023 or 2022. In June 2023, Dominion Energy entered into an agreement with Cove Point for transportation and storage services at market rates for a 20-year period commencing August 2023. In July 2023, Dominion Energy entered into an agreement to sell its 50% noncontrolling limited partnership interest in Cove Point to BHE for cash consideration of $3.3 billion which closed in September 2023 after all customary closing and regulatory conditions were satisfied, including clearance under the Hart-Scott-Rodino Act and approval from the DOE. The sale is treated as an asset sale for tax purposes. In addition, Dominion Energy received proceeds of $199 million from the settlement of related interest rate derivatives. In connection with closing, Dominion Energy utilized proceeds, as required, to repay DECP Holding’s term loan secured by its noncontrolling interest in Cove Point, which had an outstanding balance of $2.2 billion, and $750 million of outstanding borrowings under Dominion Energy’s two $600 million 364-day term loan facilities entered in July 2023. See Note 17 for additional information on these facilities. Dominion Energy recorded a gain on the sale of its noncontrolling interest in Cove Point of $626 million ($348 million after-tax) within discontinued operations in its Consolidated Statements of Income for the year ended December 31, 2023. In September 2023, as a result of Dominion Energy entering agreements for the East Ohio, PSNC and Questar Gas Transactions, Dominion Energy’s 50% noncontrolling limited partnership interest in Cove Point also met the requirements to be presented as discontinued operations and held for sale (through the date of disposal) as both disposition activities were executed in connection with Dominion Energy’s comprehensive business review announced in November 2022. In addition, interest expense associated with DECP Holding’s term loan secured by its noncontrolling interest in Cove Point and related interest rate derivatives have been classified as discontinued operations. Amounts presented in discontinued operations within Dominion Energy's Consolidated Statements of Income for the year ended December 31, 2023 include $218 million for earnings on equity method investees, $120 million of interest expense and $31 million of income tax expense, in addition to the gain on sale and associated tax expense disclosed above. Such amounts for the years ended December 31, 2022 were $277 million for earnings on equity method investees, $(160) million for interest expense (benefit) and $92 million of income tax expense. All activity relating to Dominion Energy’s noncontrolling interest in Cove Point is recorded within the Corporate and Other segment. Atlantic Coast Pipeline In September 2014, Dominion Energy, along with Duke Energy and Southern, announced the formation of the Atlantic Coast Pipeline for the purpose of constructing an approximately 600-mile natural gas pipeline running from West Virginia through Virginia to North Carolina. Following Dominion Energy’s acquisition from Southern of its 5% interest in Atlantic Coast Pipeline in 2020, Dominion Energy owns a 53% noncontrolling membership interest in Atlantic Coast Pipeline with Duke Energy owning the remaining interest. Atlantic Coast Pipeline continues to be accounted for as an equity method investment as the power to direct the activities most significant to Atlantic Coast Pipeline is shared with Duke Energy. As a result, Dominion Energy has the ability to exercise significant influence, but not control, over the investee. In July 2020, as a result of ongoing permitting delays, growing legal uncertainties and the need to incur significant capital expenditures to maintain project timing before such uncertainties could be resolved, Dominion Energy and Duke Energy announced the cancellation of the Atlantic Coast Pipeline Project. Dominion Energy recorded earnings (losses) on equity method investees of $(13) million ($(10) million after-tax), $15 million ($11 million after-tax), and $(7) million ($(5) million after-tax) for the years ended December 31, 2024, 2023 and 2022, respectively. In connection with Dominion Energy’s decision to sell substantially all of its gas transmission and storage operations, Dominion Energy has reflected the results of its equity method investment in Atlantic Coast Pipeline as discontinued operations in its Consolidated Statements of Income. As a result of its share of equity losses exceeding its investment, Dominion Energy’s Consolidated Balance Sheets at December 31, 2024 and 2023 include a liability of $7 million and $4 million, respectively, presented in other current liabilities and reflecting Dominion Energy’s obligations to Atlantic Coast Pipeline related to AROs. Dominion Energy recorded contributions of $12 million, $95 million and $3 million during the years ended December 31, 2024, 2023 and 2022, respectively, to Atlantic Coast Pipeline. 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. All activity relating to Atlantic Coast Pipeline is recorded within the Corporate and Other segment. Align RNG In the fourth quarter of 2023, Dominion Energy reflected its share of an impairment of certain property, plant and equipment at Align RNG totaling $35 million ($26 million after-tax) in other income (expense) in its Consolidated Statements of Income. All activity related to Align RNG is reflected within Contracted Energy. Dominion Privatization In February 2022, Dominion Energy entered into an agreement to form Dominion Privatization, a partnership with Patriot. Dominion Privatization, through its wholly-owned subsidiaries, maintains and operates electric and gas distribution infrastructure under service concession arrangements with certain U.S. military installations. Under the agreement, Dominion Energy contributed its existing privatization operations, excluding contracts held by DESC, and Patriot contributed cash. The initial contribution, consisting of privatization operations in South Carolina, Texas and Pennsylvania, closed in March 2022 for which Dominion Energy received total consideration of $120 million, subject to customary closing adjustments, comprised of $60 million in cash proceeds and a 50% noncontrolling ownership interest in Dominion Privatization with an initial fair value of $60 million, estimated using the market approach. This is considered a Level 2 fair value measurement given that it is based on the agreed-upon sales price. In the first quarter of 2022, Dominion Energy recorded a gain of $23 million ($16 million after-tax), presented in losses (gains) on sales of assets in its Consolidated Statements of Income. Dominion Energy’s 50% noncontrolling ownership interest in Dominion Privatization is accounted for as an equity method investment as Dominion Energy has the ability to exercise significant influence, but not control, over the investee. The second contribution, consisting of privatization operations in Virginia, closed in December 2022 for which Dominion Energy received total consideration of $215 million, subject to customary closing adjustments, comprised of $108 million in cash proceeds and retention of its 50% noncontrolling ownership interest valued at $107 million using the market approach. This is considered a Level 2 fair value measurement given that it is based on the agreed-upon sales price. In the fourth quarter of 2022, Dominion Energy recorded a gain of $133 million ($99 million after-tax), presented in losses (gains) on sales of assets in its Consolidated Statements of Income. In February 2024, Dominion Energy received a distribution of $126 million from Dominion Privatization, which was accounted for as a return of an investment. All activity related to Dominion Privatization is reflected within the Corporate and Other segment. Wrangler In March 2022, Dominion Energy sold its 15% noncontrolling partnership interest in Wrangler to Interstate Gas Supply, Inc. for cash consideration of $85 million. Dominion Energy recognized a gain of $11 million ($8 million after-tax), included in other income (expense) in its Consolidated Statements of Income reflected within the Corporate and Other segment for the year ended December 31, 2022.
