Exhibit 99.1

Unaudited Proforma Financial Information

In July 2020, Dominion Energy, Inc. and Dominion Energy Questar Corporation (collectively, Dominion Energy) entered into an agreement to sell substantially all of their gas transmission and storage operations assets, including Eastern Energy Gas Holdings, LLC f/k/a Dominion Energy Gas Holdings, LLC (Eastern Energy), to Berkshire Hathaway Energy Company (BHE). The agreement provided, among other items, that Dominion Energy would retain a 50% noncontrolling interest in Dominion Energy Cove Point LNG, LP (Cove Point). In October 2020, since approval of the transaction under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (HSR Approval), was not obtained within 75 days following the date of the agreement, Dominion Energy delivered notice to BHE of their election to terminate the transaction with respect to Dominion Energy Questar Pipeline, LLC (Questar Pipeline) and related entities (the Questar Pipeline Group). A separate agreement was entered into between Dominion Energy and BHE in October 2020 for the Questar Pipeline Group, which is currently anticipated to close in early 2021 after receipt of HSR Approval. On November 1, 2020, Eastern Energy finalized a restructuring whereby Eastern Energy contributed Questar Pipeline and a 50% noncontrolling interest in Cove Point to Dominion Energy. This restructuring was accounted for by Eastern Energy as a reorganization of entities under common control. After such restructuring, Dominion Energy closed the transaction exclusive of the Questar Pipeline Group with BHE on November 1, 2020.

The following unaudited pro forma consolidated statements of income (loss) for the year ended December 31, 2019 and the six months ended June 30, 2020 have been prepared to give effect to the distributions of Questar Pipeline and a 50% noncontrolling interest in Cove Point as if they had occurred on January 1, 2019. The following unaudited pro forma consolidated balance sheet as of June 30, 2020, has been prepared to give effect to the distributions as if they had occurred on June 30, 2020.

The unaudited pro forma financial information was prepared utilizing our historical financial data derived from the interim consolidated financial statements included in our Quarterly Report on Form 10-Q filed with the SEC on August 5, 2020 and from the audited consolidated financial statements for the period ended December 31, 2019 included in our Annual Report on Form 10-K filed with the SEC on February 28, 2020. The pro forma adjustments are described in the notes to the unaudited pro forma information and are based upon available information and assumptions that we believe are reasonable.

The unaudited pro forma financial information is for informational purposes only and is not necessarily indicative of what our financial performance and financial position would have been had the transaction been completed on the dates assumed nor is such unaudited pro forma financial information necessarily indicative of the results to be expected in any future period.

NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. BASIS OF PRESENTATION

The unaudited pro forma consolidated financial statements included herein have been derived from the following historical financial statements:

•

the audited historical financial statements of Eastern Energy for the year ended December 31, 2019; and

•

the unaudited interim financial statements of Eastern Energy as of and for the six months ended June 30, 2020.

On November 1, 2020, Eastern Energy distributed all of the issued and outstanding membership interests of Questar Pipeline and a 50% noncontrolling interest in Cove Point. The pro forma adjustments have been prepared as if the dispositions of Questar Pipeline and a 50% noncontrolling interest in Cove Point occurred on January 1, 2019 in the case of the unaudited pro forma consolidated statements of income for the year ended December 31, 2019 and for the six months ended June 30, 2020, and on June 30, 2020 in the case of the unaudited pro forma consolidated balance sheet. The adjustments are based on currently available information and certain estimates and assumptions, and therefore the actual effects of these transactions will differ from the pro forma adjustments. However, management believes that the assumptions used provide a reasonable basis for presenting the significant effects of the transactions, and that the pro forma adjustments in the unaudited pro forma consolidated financial statements give appropriate effect to the assumptions. The effects on the unaudited pro forma consolidated financial statements of the transactions described above are more fully described in Note 3.
