Item 4.

Purpose of Transaction.

The information previously provided in response to Item 4 is hereby amended and supplemented by adding the following:

On November 26, 2018, Dominion Energy, Inc. (“Dominion Energy”) and its indirect, wholly owned subsidiary, Tredegar Street Merger Sub, LLC (“Merger Sub,” and together with Dominion Energy, the “Parent Parties”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Dominion Energy Midstream Partners, LP (“DM”) and Dominion Energy Midstream GP, LLC (“DM General Partner” and, together with DM, the “DM Parties”). Pursuant to the Merger Agreement, Merger Sub will be merged with and into DM, with DM being the surviving entity (the “Merger”).

Under the terms of the Merger Agreement, each outstanding common unit representing limited partner interests in DM (the “DM Common Units”) that is held immediately before the closing of the Merger by a unitholder other than Dominion Energy and any entities that are partially or wholly owned, directly or indirectly, by Dominion Energy (such units, the “DM Public Common Units”) will be converted into the right to receive 0.2492 shares of validly issued, fully paid and non-assessable Dominion Energy common stock, without par value (the “Dominion Energy Common Stock”). Cash will be paid in lieu of any issuance of fractional shares of Dominion Energy Common Stock. Furthermore, if the record date for the regular quarterly cash dividend on the Dominion Energy Common Stock that is paid or payable during the calendar quarter ending March 31, 2019 occurs prior to the closing of the Merger, then each holder of DM Public Common Units outstanding immediately before the closing of the Merger will also be entitled to receive an amount of cash, without interest, equal to the Dominion Energy 2019 first quarter dividend that they would have been entitled to receive if (i) the closing of the Merger had occurred before the record date for the Dominion Energy 2019 first quarter dividend and (ii) on such record date, the holder of the DM Public Common Units held the number of whole shares of Dominion Energy Common Stock that such holder is entitled to receive under the conversion formula described in the preceding sentence.

In addition, under the terms of the DM partnership agreement, each outstanding Series A preferred unit representing limited partner interests in DM (the “DM Series A Preferred Units”) that is held immediately before the closing of the Merger by a unitholder other than Dominion Energy and any entities that are partially or wholly owned, directly or indirectly, by Dominion Energy (such units, the “DM Public Series A Preferred Units”), shall, immediately before the closing of the Merger, at the election of the holders of such units, either (i) convert into DM Public Common Units, (ii) be redeemed for cash or DM Public Common Units, in the sole discretion of DM or (iii) remain outstanding. Each holder of DM Public Common Units following such elections shall receive the merger consideration described above for their DM Public Common Units.

All DM Common Units, other than the DM Public Common Units, and all DM Series A Preferred Units that remain outstanding at the closing of the Merger, will remain outstanding following the Merger. Under the terms of the Merger Agreement, the closing of the Merger will occur no earlier than the day following the record date for the regular quarterly cash distribution on the DM Common Units that is paid or payable during the calendar quarter ending March 31, 2019.

The Board of Directors of Dominion Energy has approved the Merger Agreement and the transactions contemplated by the Merger Agreement, including the Merger and the issuance of Dominion Energy Common Stock in connection with the Merger. The approval of the shareholders of Dominion Energy is not required in order to complete the transactions contemplated by the Merger Agreement.

The conflicts committee (the “DM Conflicts Committee”) of the board of directors of DM General Partner (the “DM Board”) has, by unanimous vote, in good faith, approved the Merger Agreement and the transactions contemplated thereby, including the Merger, determined that they are in the best interests of DM and the holders of DM Public Common Units, and resolved to approve and recommend the approval of the Merger Agreement and the consummation of the transactions contemplated thereby, including the Merger, to the DM Board. Based upon such approval, the DM Board has unanimously approved the Merger Agreement and the transactions contemplated thereby, including the Merger, directed that the Merger Agreement be submitted to a vote of holders of DM Common Units and DM Series A Preferred Units and authorized the holders of such units to act by written consent.

The Merger Agreement contains customary representations, warranties, covenants and termination provisions. Consummation of the Merger is subject to the satisfaction or waiver of certain specified closing conditions, including, among other things: (i) the approval of the Merger Agreement and the Merger by DM’s unit holders; (ii) the effectiveness of a registration statement on Form S-4 with respect to the Dominion Energy Common Stock issuance in connection with the Merger and (iii) other customary closing conditions.

The foregoing description of the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which is attached hereto as Exhibit 1, and the terms of which are incorporated herein by reference.

The Merger Agreement is incorporated herein by reference to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual or financial information about Dominion Energy, DM, the other parties to the Merger Agreement or any of their respective subsidiaries and affiliates. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of that agreement and as of specific dates; were solely for the benefit of the parties to the Merger Agreement; may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of Dominion Energy, DM, the other parties to the Merger Agreement or any of their respective subsidiaries and affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in public disclosures by Dominion Energy and DM. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the companies and the Merger that will be contained in, or incorporated by reference into, the consent statement/prospectus that the parties will be filing in connection with the Merger, as well as in the other filings that each of Dominion Energy and DM make with the Securities and Exchange Commission (SEC).
