MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

Dear SCANA Shareholders:

The board of directors of SCANA Corporation, which we refer to as SCANA, has adopted an Agreement and Plan of Merger, which we refer to as the merger agreement, dated as of January 2, 2018, by and among Dominion Energy, Inc., which we refer to as Dominion Energy, Sedona Corp., a wholly owned subsidiary of Dominion Energy, which we refer to as Merger Sub, and SCANA.

Pursuant to the merger agreement, Merger Sub will merge with and into SCANA, which we refer to as the merger, with SCANA surviving the merger as a wholly owned subsidiary of Dominion Energy. In the merger, holders of SCANA common stock, whom we refer to as SCANA shareholders, will have the right to receive 0.6690 of a share of Dominion Energy common stock for each share of SCANA common stock held at the time of the merger, which we refer to as the merger consideration, with cash to be paid in lieu of the issuance of any fractional share of Dominion Energy common stock. The value of the merger consideration to be received in exchange for each share of SCANA common stock will fluctuate with the market value of Dominion Energy common stock. The transaction structure contemplates that the receipt of shares of Dominion Energy common stock will be tax deferred for SCANA shareholders.

SCANA will hold a special meeting of shareholders to consider the merger, which we refer to as the special meeting. Based on the number of shares of SCANA common stock outstanding on May 31, 2018, the record date for the special meeting, Dominion Energy expects to issue approximately 95,611,418 shares of Dominion Energy common stock to the SCANA shareholders. As a result, upon the completion of the merger, former SCANA shareholders will own approximately 12 to 13% of the issued and outstanding shares of Dominion Energy common stock. SCANA common stock is listed on the New York Stock Exchange, which we refer to as the NYSE, under the symbol “SCG” and Dominion Energy common stock is listed on the NYSE under the symbol “D.”

We cannot complete the merger unless the SCANA shareholders approve the proposal related to the merger and, therefore, your vote is very important. Whether or not you expect to attend the special meeting in person, please vote your shares as promptly as possible by (i) accessing the Internet website specified on your proxy card, (ii) calling the toll-free number specified on your proxy card or (iii) signing all proxy cards that you receive from us and returning them in the postage-paid envelopes provided, so that your shares of SCANA common stock may be represented and voted at the special meeting. You may change or revoke your proxy before the vote at the special meeting by following the procedures outlined in this proxy statement/prospectus.

We look forward to the successful completion of the merger.

Sincerely,

Jimmy E. Addison

Chief Executive Officer

SCANA Corporation

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE SPECIAL MEETING

The following questions and answers are intended to briefly address some questions that you, as a SCANA shareholder, may have regarding the merger, the merger agreement and the special meeting. Dominion Energy and SCANA urge you to read carefully the remainder of this proxy statement/prospectus because these questions and answers may not address all questions or provide all information that might be important to you with respect to the merger, the merger agreement and the matters being considered at the special meeting. Additional important information is also contained in the annexes and the documents incorporated by reference into this proxy statement/prospectus. You may obtain the information incorporated by reference into this proxy statement/prospectus without charge by following the instructions under the section entitled “Where You Can Find More Information” beginning on page 141 of this proxy statement/prospectus. For your convenience, these questions and answers have been divided into questions and answers about the merger and questions and answers about the special meeting.

Questions and Answers About the Merger

This proxy statement/prospectus includes important information about the merger, the merger agreement and the special meeting. SCANA shareholders should read this information carefully and in its entirety. The enclosed voting materials allow SCANA shareholders to vote their shares without attending the special meeting in person.

Your vote is very important. We encourage you to vote as soon as possible.

This proxy statement/prospectus constitutes both a proxy statement of SCANA and a prospectus of Dominion Energy. It is a proxy statement of SCANA because the SCANA board is soliciting proxies from the SCANA shareholders. It is a prospectus of Dominion Energy because Dominion Energy will issue shares of Dominion Energy common stock in exchange for outstanding shares of SCANA common stock in the merger.

iv

Former SCANA shareholders who hold SCANA share certificates will not be entitled to be paid dividends otherwise payable on the shares of Dominion Energy common stock into which their shares of SCANA common stock are exchangeable until they surrender their SCANA share certificates according to the instructions provided to them. Dividends will be accrued for these shareholders and they will receive the accrued dividends when they surrender their SCANA share certificates. Dominion Energy most recently paid a quarterly dividend on March 20, 2018 in an amount equal to $0.835 per share of Dominion Energy common stock. On May 9, 2018, the Dominion Energy board declared a quarterly dividend of $0.835 per share payable on June 20, 2018 to Dominion Energy shareholders of record on June 1, 2018. See the section entitled “Comparative Stock Prices and Dividends” beginning on page 15 of this proxy statement/prospectus.

All future Dominion Energy dividends will remain subject to approval by the board of directors of Dominion Energy, which we refer to as the Dominion Energy board.

At the effective time of the merger each deferred unit in respect of SCANA common stock, which we refer to as a deferred unit, credited or deemed credited to the SCANA stock ledger under SCANA’s Director Compensation and Deferral Plan or Executive Deferred Compensation Plan shall be converted automatically into a number of deferred unit(s) in respect of Dominion Energy common stock under such plans (which will be assumed by Dominion Energy) equal to the product of (x) such deferred unit multiplied by (y) the merger consideration, to be payable pursuant to the terms of the applicable plan.

For additional information regarding the SCANA equity compensation awards, see the section entitled “The Merger—Interests of SCANA’s Directors and Executive Officers in the Merger—Equity Compensation” beginning on page 75 of this proxy statement/prospectus.

v

You should read the section entitled “The Merger—U.S. Federal Income Tax Consequences of the Merger” beginning on page 66 of this proxy statement/prospectus for a more complete discussion of the U. S. federal income tax consequences of the merger. Tax matters can be complicated and the tax consequences of the merger to you will depend on your particular tax situation. You should consult your tax advisor to determine the tax consequences of the merger to you.

vi

SCANA will no longer be a public company, and its shares will be delisted from the NYSE, deregistered under the Exchange Act and cease to be publicly traded. SCANA shareholders of record at the effective time of the merger (as defined below) will be entitled to receive the merger consideration.

vii

For a more complete summary of these conditions and additional conditions that must be satisfied or waived prior to the closing of the merger, see the section entitled “The Merger Agreement—Conditions to Completion of the Merger” beginning on page 92 of this proxy statement/prospectus.

We cannot complete the merger unless the SCANA shareholders approve the merger proposal. If the merger agreement is not approved by SCANA shareholders or if the merger is not completed for any other reason, SCANA will remain an independent company, the SCANA shareholders will not receive any merger consideration for their shares of SCANA common stock in connection with the merger, and the shares of SCANA common stock will remain outstanding and will continue to be listed and traded on the NYSE.

Questions and Answers Regarding the Special Meeting and Voting

viii

SCANA will transact no other business at the special meeting or any adjournment or postponement thereof.

ix

If you hold shares of SCANA common stock through a broker, bank or other nominee, please follow the voting instructions provided by your broker, bank or other nominee to ensure that your shares are represented at the special meeting.

If your shares of SCANA common stock are held by a brokerage firm, trustee, bank, other financial intermediary or nominee, referred to as an intermediary, you are considered the beneficial owner of shares held in “street name,” and the intermediary is considered the shareholder of record with respect to those shares.

x

The deadline to provide voting directions for shares allocated to your Plan account through the Plan is 5:00 p.m., Eastern Daylight Time on July 27, 2018, which, for administrative reasons, is earlier than the deadline for voting SCANA common stock not held through the Plan. You will not be able to submit or change voting directions after this deadline. If you own SCANA common stock both through and outside of the Plan, you will be required to vote those shares separately.

Market Price and Dividend Data - Dominion Energy

The following table sets forth the high and low sales prices of Dominion Energy common stock as reported on the NYSE and the quarterly cash dividends declared per share in respect of Dominion Energy common stock for the calendar quarters indicated.

15

Dividends on Dominion Energy common stock are paid as declared by the Dominion Energy board. On May 9, 2018, the Dominion Energy board declared a quarterly dividend of $0.835 per share payable on June 20, 2018 to shareholders of record on June 1, 2018. Dividends are typically paid on the 20th of March, June, September and December of each year.

As of May 31, 2018, Dominion Energy had approximately 652.8 million shares of its common stock outstanding, and there were approximately 122,000 holders of record of Dominion Energy common stock.

Market Price and Dividend Data - SCANA

SCANA paid a dividend for the quarter ended March 31, 2018 of $0.6125 per share and has agreed in the merger agreement that it will not pay a quarterly dividend of more than that amount prior to the completion of the merger without Dominion Energy’s prior written consent. As previously publicly announced by SCANA, the SCANA board has deferred a decision on whether to pay a dividend for the quarter ending June 30, 2018. The decision to pay a dividend for the quarter ending June 30, 2018 and for any period thereafter, and the amount of any future dividend, will be made by the SCANA board based on many factors, including SCANA’s financial, regulatory and other circumstances at the time the decision is made.

SCANA paid quarterly dividends on its common stock of $0.6125 per share in 2017 and $0.575 per share in 2016. For additional information on the historic market price of SCANA common stock and dividends, see SCANA’s Annual Report on Form 10-K for the year ended December 31, 2017. See the section entitled “Where You Can Find More Information” beginning on page 141 of this proxy statement/prospectus.

RISK FACTORS

In addition to the other information included or incorporated by reference into this proxy statement/prospectus, including the matters addressed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 26 of this proxy statement/prospectus, you should carefully consider the following risks before deciding how to vote on the proposals set forth in this document. In addition, you should read and consider the risks associated with each of the businesses of Dominion Energy and SCANA because these risks may also affect the combined company. A description of the material risks can be found in the Annual Report on Form 10-K for the fiscal year ended December 31, 2017 for Dominion Energy and in the Quarterly Report on Form 10-Q for the quarter ended March 31, 2018 for SCANA, each of which are filed with the SEC and incorporated by reference into this proxy statement/prospectus. You should also read and consider the other information in this proxy statement/prospectus and the other documents incorporated by reference into this proxy statement/prospectus. See the section entitled “Where You Can Find More Information” beginning on page 141 of this proxy statement/prospectus.

Risk Factors Relating to the Merger

Because the market price of Dominion Energy common stock will fluctuate, SCANA shareholders cannot be certain of the market value of the merger consideration they will receive.

Upon completion of the merger, each outstanding share of SCANA common stock (other than cancelled shares) will be converted into the right to receive 0.6690 of a share of Dominion Energy common stock. The market value of Dominion Energy common stock received in the merger may vary significantly from the closing price of Dominion Energy common stock on the date Dominion Energy and SCANA announced the merger, on the date that this proxy statement/prospectus is mailed to SCANA shareholders, or on the date of the special meeting. Any change in the market price of Dominion Energy common stock prior to the completion of the merger will affect the market value of the merger consideration that SCANA shareholders will receive upon completion of the merger, which may not occur until a significant period of time has passed since the date of the special meeting, and there will be no adjustment to the merger consideration for changes in the market price of either shares of Dominion Energy common stock or shares of SCANA common stock. Neither Dominion Energy nor SCANA is permitted to terminate the merger agreement because of changes in the market price of SCANA common stock or Dominion Energy common stock. On June 7, 2018, the closing price of the Dominion Energy common stock on the NYSE was $62.39 per share.

Stock price changes may result from a variety of factors that are beyond the control of Dominion Energy and SCANA, including, but not limited to, general market and economic conditions, changes in the companies’ respective businesses, operations and prospects, regulatory considerations, litigation and speculation regarding the likelihood that the merger will be completed and the timing of completion. Therefore, at the time of the special meeting you will not know the precise market value of the consideration you will receive upon completion of the merger. As of June 7, 2018, the equivalent per share value of the merger consideration for each share of SCANA common stock based on the product of (i) the Dominion Energy per share value and (ii) 0.6690 was $41.74. You should obtain current market quotations for shares of Dominion Energy common stock and for shares of SCANA common stock.

The completion of the merger is subject to the receipt of consents, approvals and/or findings from governmental entities, which may impose conditions that could have an adverse effect on Dominion Energy or SCANA or could cause either Dominion Energy or SCANA to abandon the merger. The completion of the merger is also subject to there not having been substantive changes in certain South Carolina laws that have or would reasonably be expected to have an adverse effect on SCANA or its subsidiaries or orders of governmental entities or changes in law that impose any condition that would reasonably be expected to result in specified changes to the SCPSC petition.

Dominion Energy and SCANA are not required to complete the merger until after the applicable waiting period under the HSR Act expires or terminates and the requisite authorizations, approvals, consents and/or permits are received from the FERC, NRC, SCPSC, NCUC and GPSC. Any of the relevant governmental entities

17

may oppose the merger, fail to approve the merger, fail to make required findings in favor of the merger, or impose certain requirements or obligations as conditions for their consent, approval or findings or in connection with their review. Regulatory approvals of the merger or findings with respect to the merger may not be obtained on a timely basis or at all, and such approvals or findings may include conditions that could have an adverse effect on Dominion Energy and/or SCANA, and/or result in the abandonment of the merger. The terms of any conditions imposed in order to obtain the requisite regulatory approvals or findings may not be known by the date of the special meeting. Neither Dominion Energy nor SCANA can provide any assurance that they will obtain the necessary approvals or findings or that any required conditions will not have an adverse effect on Dominion Energy following the merger. If SCANA shareholders vote in favor of the merger proposal at the special meeting, Dominion Energy or SCANA may make decisions after the special meeting to waive a condition or approve certain actions required to obtain regulatory approvals or findings without seeking further approval of the SCANA shareholders.

Subject to the terms and conditions set forth in the merger agreement, the merger agreement may require Dominion Energy to accept conditions from regulators that could adversely impact Dominion Energy after the merger without either of Dominion Energy or SCANA having the right to refuse to close the merger on the basis of those regulatory conditions, except that Dominion Energy is generally not required, and SCANA is generally not permitted without Dominion Energy’s prior approval, to take any action or accept any condition that results in a burdensome condition, as described in the section entitled “The Merger Agreement—Reasonable Best Efforts to Obtain Regulatory Approvals” beginning on page 96 of this proxy statement/prospectus.

In addition, the merger agreement provides that Dominion Energy (but not SCANA) will have the right to refuse to complete the merger if, since the date of the merger agreement, any governmental entity shall have enacted any order, or there shall have been any change in law (including the BLRA and the other laws governing South Carolina public utilities), which imposes any material change to the terms, conditions or undertakings set forth in the SCPSC petition, or any significant changes to the economic value of the proposed terms set forth in the SCPSC petition, in each case as determined by Dominion Energy in good faith.

The merger agreement further provides that Dominion Energy (but not SCANA) will have the right to refuse to complete the merger if there shall have occurred any substantive change in the BLRA or other laws governing South Carolina public utilities which has or would reasonably be expected to have an adverse effect on SCANA or any of its subsidiaries. There are currently pending three bills that would make substantive changes to the BLRA. The bills are H. 4375, S. 954, and H. 4950, the latter of which is the South Carolina 2017-2018 Budget Bill amended to include provisos related to the SCPSC petition. These bills reside in conference committees to finalize differences between the versions of the legislation as passed. If any of these bills becomes law, Dominion Energy would not be obligated to complete the merger if it is determined that the bill has or would reasonably be expected to have an adverse effect on SCANA or any of its subsidiaries. In addition, the adjournment resolution adopted by the South Carolina General Assembly allows the leadership of the House of Representatives or Senate to reconvene those bodies to consider matters related to the NND project which could include new or additional legislation.

Certain lawsuits and regulatory actions have been filed against SCANA and SCE&G in connection with the abandonment of the NND project. If the relief requested in these matters (including a request for declaratory judgment that the BLRA is unconstitutional) is granted, Dominion Energy might not be obligated to complete the merger.

Dominion Energy and SCANA can provide no assurance that these risks will not materialize and either adversely impact SCANA prior to or Dominion Energy after the completion of the merger or result in the abandonment of the merger and adversely impact the results of operations, cash flows and financial condition of SCANA, if (i) the required authorizations, approvals, consents and/or permits are not obtained or received, or (ii) such conditions rise to the thresholds discussed above, some of which are in the subjective determination of Dominion Energy, acting in good faith (as discussed above). See the sections entitled “The Merger—Regulatory Approvals Required for the Merger” beginning on page 68 of this proxy statement/prospectus and “The Merger Agreement—Conditions to Completion of the Merger” beginning on page 92 of this proxy statement/prospectus.

Failure to complete the merger could negatively impact the stock price and the future business and financial results of SCANA.

If the merger is not completed, the ongoing business of SCANA may be adversely affected and SCANA could be subject to several risks, including the following:

In addition to the above risks, SCANA may be required, under certain circumstances, to pay to Dominion Energy a termination fee of $240 million.

If the merger is not completed, SCANA cannot assure SCANA shareholders that these risks will not materialize and will not materially affect its business, financial results and stock price.

The merger agreement contains provisions that limit SCANA’s ability to pursue alternatives to the merger, which could discourage a potential competing acquirer of SCANA or could result in any competing proposal being at a lower price than it might otherwise be.

The merger agreement contains provisions that, subject to certain exceptions, restrict SCANA’s ability to initiate, solicit, knowingly encourage, facilitate or discuss competing third-party proposals to acquire all or a significant part of SCANA, or provide information to a third party that could reasonably be expected to lead to such a proposal. See the section entitled “The Merger Agreement—Non-Solicitation of Alternative Proposals” beginning on page 99 of this proxy statement/prospectus. In addition, Dominion Energy generally has an opportunity to offer to modify the terms of the merger in response to any superior acquisition proposal that may be made before the SCANA board is permitted to withdraw or qualify its recommendation. In some circumstances on termination of the merger agreement, SCANA may be required to pay to Dominion Energy a termination fee of $240 million. See the sections entitled “The Merger Agreement—Non-Solicitation of Alternative Proposals” beginning on page 99 of this proxy statement/prospectus, “The Merger Agreement—Termination of the Merger Agreement” beginning on page 103 of this proxy statement/prospectus and “The Merger Agreement—Termination Fees” beginning on page 104 of this proxy statement/prospectus.

These provisions, which the SCANA board regards as customary for transactions for this type, could discourage a potential competing acquirer that might have an interest in acquiring all or a significant part of SCANA from considering or proposing that acquisition, even if it were prepared to pay consideration with a higher per share cash or market value than the merger consideration, or might result in a potential competing acquirer proposing to pay a lower price than it might otherwise have proposed to pay because of the added expense of the termination fee that may become payable by SCANA in certain circumstances.

19

The pendency of the merger could adversely affect the business and operations of SCANA.

In connection with the pending merger, some current or prospective customers or vendors of SCANA’s utilities may delay or defer decisions regarding their existing or proposed relationships with those utilities, which could negatively impact the operations, revenues, earnings, cash flows and expenses of SCANA, regardless of whether the merger is completed. Similarly, current and prospective employees of SCANA and its utilities may experience uncertainty about their future roles following the merger, which may materially adversely affect the ability of SCANA and its utilities to attract and retain key personnel during the pendency of the merger. In addition, due to operating covenants in the merger agreement, during the pendency of the merger, SCANA and its utilities may be unable to pursue strategic transactions, undertake significant capital projects, undertake certain significant financing or other specified transactions or pursue actions that are not in the ordinary course of business, even if such actions would prove beneficial.

Certain directors and executive officers of SCANA may have interests in the merger that may differ from, or be in addition to, the interests of SCANA shareholders.

Executive officers of SCANA negotiated the terms of the merger agreement with their counterparts at Dominion Energy, and the SCANA board approved the transactions contemplated by the merger agreement. In considering these facts and the other information contained in this proxy statement/prospectus, you should be aware that SCANA’s executive officers and directors may have interests in the merger that may be different from, or in addition to, the interests of SCANA shareholders. These interests include the accelerated vesting of equity awards, arrangements that provide for severance benefits if the employment of a SCANA executive officer is terminated under specified circumstances following the completion of the merger and rights to indemnification and director’s and officer’s liability insurance that will be available after the completion of the merger. For a detailed discussion of the interests that SCANA’s directors and executive officers may have in the merger, please see the section entitled “The Merger—Interests of SCANA’s Directors and Executive Officers in the Merger” beginning on page 75 of this proxy statement/prospectus.

SCANA shareholders will have a reduced ownership and voting interest in the combined company.

SCANA shareholders currently have the right to vote in the election of directors of SCANA and on certain other matters affecting SCANA. Following the merger, each SCANA shareholder will become a shareholder of Dominion Energy with a percentage ownership of the combined company that is much smaller than the shareholder’s percentage ownership of SCANA. It is expected that the former SCANA shareholders as a group will own approximately 12 to 13% of the outstanding shares of Dominion Energy common stock immediately after the completion of the merger. Because of this, the SCANA shareholders, as a group, will have substantially less influence on the management and policies of Dominion Energy than they now have, as a group, with respect to the management and policies of SCANA.

Dominion Energy expects to incur substantial expenses related to the merger.

Dominion Energy expects to incur relatively significant expenses in connection with completing the merger. While Dominion Energy has assumed that a certain level of transaction and integration expenses would be incurred, there are a number of factors beyond its control that could affect the total amount or the timing of its integration expenses. Many of the expenses that will be incurred, by their nature, are difficult to estimate accurately at the present time.

Following the merger, Dominion Energy may be unable to successfully integrate SCANA’s businesses.

Dominion Energy and SCANA currently operate as independent public companies. After the merger, Dominion Energy will be required to devote significant management attention and resources to integrating

20

SCANA’s business. Potential difficulties Dominion Energy may encounter in the integration process include the following:

For these reasons, you should be aware that it is possible that the integration process following the merger could result in the distraction of Dominion Energy’s management, the disruption of Dominion Energy’s ongoing business or inconsistencies in its services, standards, controls, procedures and policies, any of which could adversely affect the ability of Dominion Energy to maintain or establish relationships with current and prospective customers, vendors and employees or could otherwise adversely affect the business and financial results of Dominion Energy.

Dominion Energy and SCANA may be materially adversely affected by negative publicity related to the merger and in connection with other related matters, including the abandonment of the NND project.

From time to time, political and public sentiment in connection with the merger and in connection with other matters, including the abandonment of the NND project, has resulted and may continue to result in a significant amount of adverse press coverage and other adverse public statements affecting Dominion Energy and SCANA. Adverse press coverage and other adverse statements, whether or not driven by political or public sentiment, have resulted and may continue to result in investigations by regulators, legislators and law enforcement officials or in legal claims. Responding to these investigations and lawsuits, regardless of the ultimate outcome of the proceedings, as well as responding to and addressing adverse press coverage and other adverse public statements, can divert the time and effort of senior management from the management of Dominion Energy’s and SCANA’s respective businesses.

Addressing any adverse publicity, governmental scrutiny or enforcement or other legal proceedings is time consuming and expensive and, regardless of the factual basis for the assertions being made, can have a negative impact on the reputation of Dominion Energy and SCANA, on the morale and performance of their employees and on their relationships with their respective regulators, customers and commercial counterparties. It may also have a negative impact on their ability to take timely advantage of various business and market opportunities. The direct and indirect effects of negative publicity, and the demands of responding to and addressing it, may have a material adverse effect on Dominion Energy’s and SCANA’s respective business, financial condition, results of operations and prospects.

The market price of Dominion Energy common stock after the merger may be affected by factors different from those affecting the market price of SCANA common stock currently.

Upon completion of the merger, holders of SCANA common stock will become holders of Dominion Energy common stock. Dominion Energy’s business differs in important respects from that of SCANA, and,

21

accordingly, the results of operations of the combined company and the market price of Dominion Energy common stock after the completion of the merger may be affected by factors different from those currently affecting the independent results of operations of each of Dominion Energy and SCANA. For a discussion of the businesses of Dominion Energy and SCANA and of some important factors to consider in connection with those businesses, see the documents incorporated by reference in this proxy statement/prospectus and referred to under the section entitled “Where You Can Find More Information” beginning on page 141 of this proxy statement/prospectus.

The market value of Dominion Energy common stock could decline if large amounts of its common stock are sold following the merger; the market value of Dominion Energy’s common stock could also decline as a result of issuances and sales of Dominion Energy common stock other than in connection with the merger.

Following the merger, shareholders of Dominion Energy and former SCANA shareholders will own interests in a combined company operating an expanded business with more assets and a different mix of liabilities. Current shareholders of Dominion Energy and SCANA may not wish to continue to invest in the combined company, or may wish to reduce their investment in the combined company, in order to comply with institutional investing guidelines, to increase diversification or to track any rebalancing of stock indices in which Dominion Energy common stock or SCANA common stock is or was included. If, following the merger, large amounts of Dominion Energy common stock are sold, the price of its common stock could decline.

Furthermore, Dominion Energy cannot predict the effect that issuances and sales of its common stock, whether taking place before the merger (subject to the limitations of the merger agreement) or after the merger, including issuances and sales in connection with capital markets transactions, such as the forward sale of Dominion Energy common stock entered into in March 2018, or acquisition transactions, such as this offering, or other transactions, may have on the market value of its common stock. The issuance and sale of substantial amounts of its common stock could adversely affect the market value of such common stock.

The merger may not be accretive to operating earnings and may cause dilution to Dominion Energy’s earnings per share, which may negatively affect the market price of Dominion Energy common stock.

Dominion Energy currently anticipates that the merger will be immediately accretive to Dominion Energy’s forecasted operating earnings per share on a standalone basis. This expectation is based on preliminary estimates, which may materially change. Dominion Energy may encounter additional transaction and integration-related costs, may fail to realize all of the benefits anticipated in the merger or be subject to other factors that affect preliminary estimates or its ability to realize operational efficiencies. Any of these factors could cause a decrease in Dominion Energy’s operating earnings per share or decrease or delay the expected accretive effect of the merger and contribute to a decrease in the price of Dominion Energy’s common stock. Dominion Energy expects that the initial effect of the merger on its GAAP earnings will be a decrease in such earnings due to anticipated charges for refunds to SCE&G electric customers, write-offs of regulatory assets and transaction costs.

Pending litigation against SCANA and Dominion Energy could result in an injunction preventing the completion of the merger or may adversely affect the combined company’s business, financial condition or results of operations following the merger.

Following the announcement of the merger, four lawsuits have been filed asserting claims relating to the merger. First, an existing derivative lawsuit was amended to assert direct claims on behalf of a putative class of SCANA shareholders in the Court of Common Pleas of the County of Richland, South Carolina against the members of the SCANA board, Dominion Energy and Merger Sub, alleging breaches of various fiduciary duties by the members of the SCANA board in connection with the merger and alleging that Dominion Energy and Merger Sub aided and abetted such alleged breaches. Second, two putative class actions on behalf of SCANA shareholders have been filed in the Court of Common Pleas of the Counties of Lexington and Richland, South Carolina, respectively. The first of these lawsuits alleges that an officer of SCANA and certain members of the SCANA board breached various fiduciary duties in connection with the merger, and that SCANA, Dominion

22

Energy and Merger Sub aided and abetted such alleged breaches. The second of these lawsuits alleges that certain members of the SCANA board breached various fiduciary duties in connection with the merger, and that Dominion Energy and Merger Sub aided and abetted the alleged breaches. Among other remedies, the plaintiffs in each case seek to enjoin the merger and rescind the merger agreement. In addition, the second and third lawsuits seek in the alternative, should the merger be completed, an award of unspecified monetary damages. The fourth lawsuit is a complaint for violations of federal securities laws filed in the United States District Court for the District of South Carolina. This lawsuit asserts a claim for securities laws violations against SCANA and members of the SCANA board, and a claim for aiding and abetting against Dominion Energy and Merger Sub, in each case arising out of alleged misstatements and omissions in the Form S-4 containing a preliminary proxy statement of SCANA filed on February 14, 2018. Plaintiff seeks an order requiring defendants to disclose the alleged omitted or misrepresented information and/or an injunction to prevent consummation of the merger unless and until the alleged omitted or misrepresented information is disclosed.

While the defendants believe that dismissal is warranted, the outcome of any such litigation is inherently uncertain. The defense or settlement of any lawsuit or claim that remains unresolved at the time the merger closes may adversely affect the combined company’s business, financial condition or results of operation. See the section entitled “The Merger—Litigation Relating to the Merger” beginning on page 73 of this proxy statement/prospectus for more detail.

Derivative actions are pending against certain current and former SCANA directors and officers, the outcomes of which are uncertain; the actions are not likely to be resolved before the effective time of the merger, and the cost and recovery, if any, following the merger will burden or benefit, as applicable, all Dominion Energy shareholders and not only those Dominion Energy shareholders who had been SCANA shareholders; and it will not be known at the time of the SCANA special meeting whether the underlying claims in the derivative actions will be pursued against current and former SCANA directors and officers following the effective time of the merger.

Derivative actions have been filed in South Carolina state and federal court by putative shareholders of SCANA, asserting breach of fiduciary duty and other state law claims on behalf of SCANA against certain of SCANA’s current and former directors and officers, as described in the sections entitled “The Merger—Litigation Relating to the Merger” and “The Merger—Other Legal Proceedings” beginning on pages 73 and 74, respectively, of this proxy statement/prospectus. Although the underlying claims of SCANA asserted in the derivative actions would survive the closing of the merger, those claims would become controlled by Dominion Energy after the merger. Consequently, for purposes of voting on the merger, SCANA shareholders should assume that if the merger becomes effective, the plaintiffs in the pending derivative actions would lose their standing as SCANA shareholders to continue pursuing the derivative claims in those suits. If the claims asserted in the derivative actions have not been resolved prior to the effective time of the merger, the Dominion Energy board may have the opportunity to determine whether it is in the best interest of Dominion Energy shareholders to pursue those claims. Additionally, Dominion Energy shareholders, including current SCANA shareholders who become Dominion Energy shareholders through the merger, may make a demand on the Dominion Energy board to pursue those claims. Whether any such demand will result in Dominion Energy pursuing such claims, or if not, whether Dominion Energy shareholders would thereafter choose to pursue such claims as so-called double derivative claims, is not known. Thus, if the claims are not resolved prior to the effective time of the merger, it is possible that the derivative claims will not be pursued, despite the allegation by the plaintiffs in the derivative actions that such claims have substantial value to SCANA.

Moreover, while recovery, if any, on the derivative claims in the derivative actions obtained in the absence of the merger would benefit only SCANA and, indirectly as a result, SCANA shareholders, if the derivative claims are successfully pursued by Dominion Energy or its shareholders following the effective time of the merger, any recovery by them will benefit Dominion Energy, and current SCANA shareholders are only expected to own approximately 12 to 13% of the issued and outstanding Dominion Energy common stock as a result of the merger. At the same time, if such claims are unsuccessfully pursued by Dominion Energy the costs

23

related thereto will burden Dominion Energy. In addition, any recovery by Dominion Energy after the effective time of the merger may be substantially or completely offset by the obligation of Dominion Energy under the merger agreement to indemnify, and to cause SCANA to honor its obligations to indemnify, directors and officers of SCANA for liabilities relating to their service prior to the effective time of the merger. See the section entitled “The Merger—Interests of SCANA’s Directors and Executive Officers in the Merger—Director and Officer Indemnification” beginning on page 79 of this proxy statement/prospectus.

The unaudited pro forma combined financial information and prospective financial information included in this proxy statement/prospectus are presented for illustrative purposes only and do not represent the actual financial position or results of operations of the combined company following the merger.

The unaudited pro forma combined financial information and prospective financial information contained in this proxy statement/prospectus are presented for illustrative purposes only, contain a variety of adjustments, assumptions and preliminary estimates and do not represent the actual financial position or results of operations of Dominion Energy and SCANA prior to the merger or that of the combined company following the merger for several reasons. See the sections entitled “Equivalent and Comparative Per Share Information” beginning on page 14 of this proxy statement/prospectus and “Unaudited Pro Forma Consolidated Financial Statements” beginning on page 116 of this proxy statement/prospectus.

The actual financial positions and results of operations of Dominion Energy and SCANA prior to the merger and those of the combined company following the merger may not be consistent with, or evident from, the unaudited pro forma combined financial information and prospective financial information included in this proxy statement/prospectus. In addition, the assumptions used in preparing the unaudited pro forma combined financial information and prospective financial information included in this proxy statement/prospectus may not prove to be accurate and may be affected by other factors. Any significant changes in the share price of Dominion Energy may cause a significant change in the purchase price and the pro forma financial information.

Dominion Energy has goodwill and other intangible assets on its balance sheet, and these amounts will increase as a result of the merger. If its goodwill or other intangible assets become impaired in the future, Dominion Energy may be required to record a significant, non-cash charge to earnings and reduce its shareholders’ equity.

Upon the completion of the merger, Dominion Energy will record as goodwill the excess of the purchase price paid by Dominion Energy over the fair value of SCANA’s assets and liabilities as determined for financial accounting purposes. Under GAAP, intangible assets are reviewed for impairment on an annual basis or more frequently whenever events or circumstances indicate that its carrying value may not be recoverable. If Dominion Energy’s intangible assets, including goodwill as a result of the merger, are determined to be impaired in the future, Dominion Energy may be required to record a significant, non-cash charge to earnings during the period in which the impairment is determined.

The shares of Dominion Energy common stock to be received by SCANA shareholders as a result of the merger will have different rights from the shares of SCANA common stock.

Upon completion of the merger, SCANA shareholders will become Dominion Energy shareholders and their rights as shareholders will be governed by the Virginia Stock Corporation Act, which we refer to as the VSCA, and Dominion Energy’s amended and restated articles of incorporation, which we refer to as the Dominion Energy charter, and amended and restated bylaws, which we refer to as the Dominion Energy bylaws. The rights associated with SCANA common stock are different from the rights associated with Dominion Energy common stock. See the section entitled “Comparison of Shareholder Rights” beginning on page 126 of this proxy statement/prospectus for a summary of the material differences between the rights of holders of Dominion Energy common stock and the rights of holders of SCANA common stock.

24

The merger may fail to qualify as a tax-deferred reorganization for federal tax purposes, resulting in the SCANA shareholders’ recognition of taxable gain or loss in respect of their SCANA common stock.

Dominion Energy and SCANA intend the merger to qualify as a reorganization within the meaning of Section 368(a) of the Code. At the time of effectiveness of the registration statement relating to this proxy statement/prospectus, Dominion Energy and SCANA have obtained written tax opinions from Morgan, Lewis & Bockius, LLP, special tax counsel to Dominion Energy, and from Mayer Brown LLP, legal counsel to SCANA, respectively, that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. In addition, Dominion Energy and SCANA expect to receive written tax opinions from Morgan, Lewis & Bockius LLP and Mayer Brown LLP, respectively, dated the closing date of the merger, to the effect that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Such tax opinions were and will be based on customary assumptions and representations made by Dominion Energy and SCANA, as well as certain covenants and undertakings by Dominion Energy and SCANA. Such opinions will not bind the Internal Revenue Service, which we refer to as the IRS, or any court, or prevent the IRS from adopting a contrary position. In addition, neither Dominion Energy nor SCANA intends to request a ruling from the IRS regarding the U. S. federal income tax consequences of the merger. Accordingly, even with the tax opinions that conclude that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code, no assurance can be given that the IRS, will not challenge the conclusions reflected in the opinion or that a court would not sustain such a challenge. If the merger fails to qualify as a reorganization, a SCANA shareholder generally would recognize gain or loss for U. S. federal income tax purposes on each share of SCANA common stock surrendered in an amount equal to the difference between such shareholder’s adjusted tax basis in that share and the fair market value of the merger consideration received in exchange for that share upon completion of the merger. SCANA shareholders should read the section entitled “The Merger—U.S. Federal Income Tax Consequences of the Merger” beginning on page 66 of this proxy statement/prospectus and consult their own tax advisors regarding the U.S. federal income tax consequences of the merger to SCANA shareholders in their particular circumstances.

THE SPECIAL MEETING

Date, Time and Place

The special meeting will be held at 9:00 a.m., Eastern Daylight Time on July 31, 2018 at the Columbia Conference Center, 169 Laurelhurst Avenue, Columbia, South Carolina 29210. Registration will begin at 8:30 a.m.

Purpose of the Special Meeting

The special meeting is being held for the SCANA shareholders to consider and vote on the following proposals:

Recommendations of the SCANA Board

The SCANA board unanimously (i) determined that it is in the best interests of SCANA and the SCANA shareholders that SCANA enter into the merger agreement and complete the merger and the other transactions contemplated by the merger agreement on the terms and subject to the conditions set forth in the merger agreement, (ii) adopted the merger agreement and approved the transactions contemplated by the merger agreement, including the merger, (iii) directed that the approval of the merger agreement be submitted to a vote at a meeting of the SCANA shareholders and (iv) resolved to recommend that the SCANA shareholders approve the merger agreement, which we refer to as the SCANA board recommendation. For a description of factors considered by the SCANA board in making the above recommendation, see the section entitled “The Merger—SCANA’s Reasons for the Merger; Recommendation of the SCANA Board” beginning on page 43 of this proxy statement/prospectus.

The SCANA board recommends that you vote (i) “FOR” the merger proposal, (ii) “FOR” the merger-related compensation proposal and (iii) “FOR” the adjournment proposal.

Record Date; Stock Entitled to Vote

Only holders of record of shares of SCANA common stock at the close of business on May 31, 2018 are entitled to notice of, and to vote at, the special meeting and at any adjournment or postponement of the special meeting. We refer to this date as the record date for the special meeting. Upon written request by a SCANA shareholder, a list of SCANA shareholders entitled to vote at the special meeting will be available for inspection at SCANA’s Corporate Headquarters, 100 SCANA Parkway, Cayce, South Carolina 29033, during business hours from June 8, 2018 through the date of the special meeting. The list will also be available at the special meeting for examination by any shareholder of record of SCANA present at the special meeting.

As of the record date for the special meeting, the directors and executive officers of SCANA as a group owned and were entitled to vote 475,107 shares of SCANA common stock, or approximately 0.3324% of the outstanding shares of SCANA common stock on that date. SCANA currently expects that its directors and executive officers will vote their shares in favor of approval of the merger proposal, but none of SCANA’s directors or executive officers have entered into any agreement obligating them to do so.

30

Quorum

A quorum requires the presence, in person or by proxy, of the holders of a majority of the shares of SCANA common stock outstanding and entitled to vote. A quorum is needed to conduct the votes on the merger proposal and the merger-related compensation proposal. Abstentions, if any, will be counted as present and entitled to vote for purposes of determining the presence or absence of a quorum.

Required Vote

Approval of the merger proposal requires the affirmative vote of the holders of at least two-thirds of the outstanding shares of SCANA common stock.

The merger-related compensation proposal will be approved if more votes are cast in favor of the proposal than against the proposal. Because the vote on the merger-related compensation proposal is non-binding, if the merger agreement is approved by the SCANA shareholders and the merger is completed, the compensation that is the subject of the merger-related compensation proposal, which includes amounts SCANA is contractually obligated to pay, would still be paid regardless of the outcome of the non-binding advisory vote.

The adjournment proposal will be approved if more votes are cast in favor of the proposal than against the proposal.

Abstentions and Broker Non-Votes

Your failure to vote, or failure to instruct your broker, bank or other nominee to vote, or your abstention from voting, will have the same effect as a vote against the merger proposal (unless your shares are held through the Plan, as described on page xi of this proxy statement/prospectus), but will not be counted as a vote “for” or “against” the merger-related compensation proposal or the adjournment proposal. If you own shares of SCANA common stock as a participant in the Plan, and you do not instruct the Plan’s trustee how your Plan shares are to be voted, the Plan trustee will instruct the proxy agents to vote your shares in the same proportion as the Plan shares for which the Plan’s trustee received instructions were voted.

Voting at the Special Meeting

Whether or not you plan to attend the special meeting, please promptly vote your shares of SCANA common stock by submitting a proxy to ensure your shares are represented at the meeting. You may also vote in person at the special meeting.

Voting in Person

An admission ticket or proof of share ownership as of the record date is required to attend the special meeting in person. If you plan to use the admission ticket, please remember to detach the admission ticket from your proxy card before mailing your proxy card. If you forget to bring the admission ticket, you will be admitted to the special meeting only if you are listed as a shareholder of record as of the record date and you bring proof of identification. If you hold your shares through a broker, bank or other nominee, you must provide proof of ownership by bringing either a copy of the voting instruction card provided by your broker, bank or other nominee or a brokerage statement showing your share ownership as of the record date. If you are a shareholder of record and your shares are owned jointly and you need an additional admission ticket, you should contact the SCANA Corporate Secretary, SCANA Corporation, 220 Operation Way, Mail Code D133, Cayce, South Carolina 29033, or call 803-217-7568.

You may vote in person at the special meeting by submitting your signed proxy card or requesting a ballot at the special meeting. Please note, however, that if your shares of SCANA common stock are held in “street name,” which means your shares of SCANA common stock are held of record by a broker, bank or other nominee, and you wish to vote at the special meeting, you must bring to the special meeting a “legal proxy” from the record holder (your broker, bank or other nominee) of the shares of SCANA common stock authorizing you to vote at the special meeting.

31

Voting by Proxy

You should vote your proxy even if you plan to attend the special meeting. You can always change your vote at the special meeting or revoke your proxy before the special meeting.

Your enclosed proxy card includes specific instructions for voting your shares of SCANA common stock. SCANA’s electronic voting procedures are designed to authenticate your identity and to ensure that your votes are accurately recorded. When the accompanying proxy is returned properly executed, the shares of SCANA common stock represented by it will be voted at the special meeting or any adjournment or postponement thereof in accordance with the instructions contained in the proxy.

If you return your signed proxy card without indicating how you want your shares of SCANA common stock to be voted with regard to a particular proposal, your shares of SCANA common stock will be voted in favor of each such proposal. Proxy cards that are returned without a signature will not be counted as present at the special meeting and cannot be voted.

If your shares of SCANA common stock are held in an account with a broker, bank or other nominee, you have received a separate voting instruction card in lieu of a proxy card and you must follow those instructions in order to vote.

Changing or Revoking Your Proxy or Voting Instructions

You have the power to change your vote (i.e., revoke your proxy) at any time before your proxy is voted at the special meeting. If you are a shareholder of record (i.e., you hold your shares directly in your name), you may accomplish this by granting a new proxy (by telephone, Internet or mail) bearing a later date or by attending the special meeting and voting in person (each of which automatically revokes the earlier proxy). However, your attendance at the special meeting alone will not revoke any proxy that you have previously given. If you hold your shares in “street name,” you must follow the instructions on the voting instruction card you received from your broker, bank or other nominee in order to change or revoke your instructions. If you own shares of SCANA common stock as a participant in the Plan, you must follow the directions you receive from the Plan’s trustee in order to change or revoke your vote. As described on page xi of this proxy statement/prospectus, there is a deadline for providing directions for voting shares allocated to a Plan account that is earlier than the deadline for voting shares not held through the Plan.

Solicitation of Proxies

SCANA has engaged Georgeson LLC to assist in the solicitation of proxies for the special meeting and has agreed to pay them a fee of approximately $20,000 for their services plus associated costs and expenses. In addition to the use of the mail, proxies may be solicited by officers and directors and regular employees of SCANA, without additional remuneration, by personal interview, telephone, electronic communication or otherwise. SCANA will also request brokers, banks and nominees to forward proxy materials to the beneficial owners of shares of SCANA common stock held of record on the record date and will provide customary reimbursement to such firms for the cost of forwarding these materials.

THE MERGER

Effects of the Merger

Upon completion of the merger, Merger Sub will be merged with and into SCANA. SCANA will be the surviving corporation.

At the effective time of the merger, each share of SCANA common stock issued and outstanding immediately prior to the effective time of the merger (other than cancelled shares), whether represented by a SCANA stock certificate or in non-certificated form and represented by book-entry, will be automatically converted into the right to receive the merger consideration.

Dominion Energy will not issue fractional shares of Dominion Energy common stock in the merger. Instead, each SCANA shareholder who would otherwise be entitled to receive fractional shares of Dominion Energy common stock in the merger (after aggregating all fractional shares of Dominion Energy common stock issuable to such holder) will be entitled to an amount of cash, without interest, rounded to the nearest cent, equal to the product of (i) the amount of such fractional shares of Dominion Energy common stock issuable to such holder and (ii) the volume-weighted average price, rounded to four decimal places, of Dominion Energy common stock for the ten consecutive trading days ending on and including the second trading day prior to the effective time of the merger, which we refer to as the average price.

Background of the Merger

In 2007, lawmakers in South Carolina passed the BLRA which was intended to encourage investment in nuclear construction by enabling electric utilities to finance that investment by commencing to recover financing costs incurred during construction rather than having to wait until the units were placed into service. In 2008, SCE&G and Santee Cooper announced plans to construct the two Westinghouse AP1000 Advanced Passive Safety nuclear units in Jenkinsville, South Carolina which would serve as the centerpiece of the NND project. In 2009, the SCPSC approved SCE&G’s combined application pursuant to the BLRA and other laws seeking a certificate of environmental compatibility and public convenience and necessity and for a base load review order relating to the proposed construction and operation by SCE&G and Santee Cooper of the two nuclear units contemplated by the NND project. In 2012, SCE&G and Santee Cooper received a Combined Operating License from the NRC with respect to the NND project, and in 2013, SCE&G and Santee Cooper officially commenced nuclear construction on the two nuclear units that were the centerpiece of the NND project.

Senior management of SCANA and the SCANA board regularly review and discuss SCANA’s business strategies and prospects.

In late 2016, in light of then-current facts and circumstances related to the electric and gas utility industries in general and SCANA in particular, senior management of SCANA and the SCANA board began preliminary preparations with respect to a process to proactively explore the possibility of a potential strategic transaction. These preliminary preparations included high-level discussions with Mayer Brown LLP, SCANA’s outside legal counsel which we refer to as Mayer Brown, and with Morgan Stanley and RBC Capital Markets, although neither Morgan Stanley nor RBC Capital Markets was formally engaged by SCANA as a financial advisor in connection with exploring the possibility of a potential strategic transaction at this time. These discussions included consulting with Morgan Stanley and RBC Capital Markets regarding certain third parties that Morgan Stanley and RBC Capital Markets would suggest contacting regarding their interest in a potential strategic transaction involving SCANA if the SCANA board elected to commence a process to explore the possibility of a potential strategic transaction. In mid-December 2016, the SCANA board, having completed these preliminary preparations, elected to defer a formal decision about whether or not to commence a process to explore the possibility of a potential strategic transaction until early January 2017. However, in late December 2016 there

33

were developments that raised questions about the financial well-being of Westinghouse Electric Company LLC, which we refer to as Westinghouse, the primary contractor on the NND project with which SCE&G had a fixed price contract for Westinghouse’s services in connection with the construction of the NND project. In light of these developments, the SCANA board elected in early January 2017 not to commence a process to explore the possibility of a potential strategic transaction.

On March 29, 2017, Westinghouse filed voluntary petitions under Chapter 11 of the U.S. Bankruptcy Code and, in doing so, indicated an intention to reject the fixed price contract with SCE&G for Westinghouse’s services in connection with the construction of the NND project. In connection therewith, SCE&G and Santee Cooper entered into an Interim Assessment Agreement with Westinghouse concerning the NND project. This agreement was designed to allow for a transition and evaluation period during which SCE&G and Santee Cooper could continue to make progress on the NND project.

Westinghouse’s circumstances led SCANA to undertake an extensive analysis of possible alternatives then available for the NND project. In the months following the Westinghouse bankruptcy filing, in addition to extensively analyzing possible alternatives available for the NND project, senior management of SCANA and the SCANA board also considered various strategic alternatives available to SCANA under the circumstances.

In late March 2017, the chief executive officer of another utility company, which we refer to as Party A, approached Kevin B. Marsh, who was at that time the Chairman of the Board, President and Chief Executive Officer of SCANA, at an industry event they were both attending and told Mr. Marsh that Party A would be interested in talking to SCANA if SCANA decided at some point that it was interested in potentially pursuing a strategic transaction. Mr. Marsh informed D. Maybank Hagood, who was at that time the lead independent director of the SCANA board, of this conversation shortly after it occurred and then informed the SCANA board of this conversation at the next regularly scheduled board meeting on April 27, 2017.

On May 5, 2017, Mr. Marsh and Thomas F. Farrell, II, Dominion Energy’s Chairman, President and Chief Executive Officer, met in Columbia, South Carolina. The meeting was arranged at the request of Mr. Farrell. At this meeting, Mr. Farrell conveyed to Mr. Marsh various concepts and potential terms related to a potential strategic transaction between SCANA and Dominion Energy. These concepts and terms, which Mr. Farrell indicated did not constitute an offer with respect to a potential transaction, included, among other things, preliminary indications regarding the potential consideration (consisting of up to 50% cash and the remainder Dominion Energy common stock and reflecting in total a premium of approximately 15% over the recent price of SCANA common stock) that would be received by SCANA’s shareholders in connection with the transaction. Mr. Marsh told Mr. Farrell that SCANA was still in the process of evaluating the NND project and that he would get back to him when the evaluation process was substantially complete.

Later on May 5, 2017, a telephonic meeting of the SCANA board was held. Members of SCANA’s senior management and representatives of Mayer Brown attended the meeting. At this meeting Mr. Marsh described for the SCANA board the meeting he had with Mr. Farrell earlier that day. The SCANA board discussed whether, in light of the preliminary interest in a potential strategic transaction expressed by Dominion Energy, it was prudent to commence a process to explore the possibility of a potential strategic transaction. In light of the considerable uncertainty surrounding the NND project and the challenges that third parties would have in valuing SCANA in light of those uncertainties, the SCANA board elected not to do so at that time.

On May 12, 2017, in a meeting arranged by Mr. Marsh, Mr. Marsh had a conversation with the chief executive officer of another utility company, which we refer to as Party B, and asked whether Party B might be interested in acquiring an ownership interest in the NND project. The chief executive officer responded that Party B would consider the matter. On May 22, 2017, the chief executive officer of Party B informed Mr. Marsh that Party B was not interested in acquiring an ownership interest in the NND project.

In mid-June 2017, Mr. Marsh called Mr. Farrell, telling him that SCANA’s evaluation of the NND project was taking longer than expected and that he still planned to get back to him with respect to the conceptual

34

proposal made by Mr. Farrell at their meeting on May 5, 2017 after more progress was made in the evaluation of the NND project.

On June 26, 2017, SCANA and Santee Cooper announced that the Interim Assessment Agreement with Westinghouse concerning the NND project had been amended to extend the term of the agreement through August 10, 2017. The agreement extension allowed SCANA and Santee Cooper additional time to maintain their options by continuing construction on the NND project, while examining relevant information for a thorough and careful assessment to determine the most prudent path forward.

On July 12, 2017, Mr. Marsh and Jimmy E. Addison, who was at that time the Executive Vice President and Chief Financial Officer of SCANA, met with Mr. Farrell and Mark F. McGettrick, Dominion Energy’s Executive Vice President and Chief Financial Officer, in Columbia, South Carolina. The meeting was arranged at the request of Mr. Marsh. At the meeting, Mr. Marsh stated that he was not going to respond to the conceptual proposal communicated by Mr. Farrell at their meeting on May 5, 2017, but rather wanted to provide Dominion Energy with an update regarding SCANA’s evaluation of the NND project and to convey to Dominion Energy certain additional information about SCANA’s situation and circumstances and about Santee Cooper and its generation needs for the future. Mr. Marsh asked Mr. Farrell if Dominion Energy had any interest in acquiring all or a portion of Santee Cooper’s interest in the NND project. Mr. Farrell said that Dominion Energy had no such interest. Rather, Mr. Farrell stated that Dominion Energy was interested in proceeding with a due diligence review for a strategic transaction with SCANA. Mr. Marsh responded that SCANA was not prepared to proceed with that step at that time. The participants in the meeting then discussed certain of the terms that would need to be considered if the parties were to proceed to evaluate a strategic transaction. At the end of this meeting, the representatives of SCANA and Dominion Energy agreed to keep in touch as developments warranted.

On July 17, 2017, an in-person meeting of the SCANA board was held. Members of SCANA’s senior management and representatives of Mayer Brown, Morgan Stanley and RBC Capital Markets attended this meeting. At this meeting, the SCANA board engaged in an extensive evaluation and discussion of various alternatives available for the NND project: complete both units, complete one unit and abandon (or postpone further construction of) the other unit or abandon both units. The SCANA board noted that its decision with respect to these three alternatives was heavily dependent on Santee Cooper’s decision regarding its interest in the NND project. Also at that meeting, Mr. Marsh described to the SCANA board the meeting with the representatives of Dominion Energy on July 12, 2017 and further discussions ensued among the directors, management and the advisors regarding the NND project, the meeting with Dominion Energy and other related matters. After discussion, the SCANA board concluded not to pursue further discussions with Dominion Energy or others regarding a strategic transaction at that time.

On July 27, 2017, SCANA and Santee Cooper issued a joint press release that stated, among other things, that there were significant challenges to completing construction of one or both units of the NND project.

On July 31, 2017, Santee Cooper announced its decision to suspend construction of the NND project. Later on July 31, 2017, following a telephonic meeting of the SCANA board, SCE&G announced that, in light of its analysis and evaluation of the NND project and Santee Cooper’s decision to suspend construction, it would cease construction on the NND project. This announcement led various stakeholders, including rate payers, shareholders, legislative committees, regulators, and other government officials, to commence inquiries into, and in some cases legal challenges with respect to, SCANA’s decision to cease construction on the NND project, many of which inquiries and legal challenges remain ongoing.

On August 1, 2017, SCE&G presented the results of its evaluation of the costs necessary to complete the NND project and the basis of its decision to abandon the project in an Allowable Ex Parte Communication Briefing to the SCPSC and filed a petition with the SCPSC under the BLRA seeking, among other things, recovery of certain costs related to the construction of the NND project in light of the decision to abandon construction.

35

In early August 2017, Mr. Marsh received a call from an executive of another utility company, which we refer to as Party C. During this call, the executive of Party C indicated to Mr. Marsh that Party C would be interested in talking to SCANA if SCANA was interested in pursuing a strategic transaction. At about that time, the chief executive officer of Party A also contacted Mr. Marsh and re-expressed Party A’s interest in discussing a strategic transaction with SCANA if SCANA was interested in such a transaction. Also at about that time, Mr. Marsh had a conversation with the chief executive officer of Party B in which Party B did not raise the topic of a possible strategic transaction with SCANA. Mr. Marsh informed the SCANA board of these conversations shortly after they took place.

On August 15, 2017, SCE&G voluntarily withdrew the petition it had filed with the SCPSC on August 1, 2017 under the BLRA in response to concerns raised by various stakeholders with respect to the petition, and to allow adequate time for governmental officials to conduct their reviews.

On September 26, 2017, the office of Alan Wilson, the Attorney General for the State of South Carolina, issued an opinion of Robert D. Cook, the Solicitor General for the State of South Carolina, contending, among other things, that the BLRA was “suspect” under the Constitution of the United States and the Constitution of the State of South Carolina.

Following up on a telephone call from Mr. Farrell on September 29, 2017, on October 1, 2017, Mr. Marsh and Mr. Addison met with Mr. Farrell and Mr. McGettrick in Columbia, South Carolina at Mr. Farrell’s request. At this meeting, Mr. Farrell conveyed to Mr. Marsh and Mr. Addison various concepts and potential terms related to a potential strategic transaction between SCANA and Dominion Energy. These concepts and terms, which Mr. Farrell indicated did not constitute an offer with respect to a potential transaction, were intended to address the various issues that had arisen since SCE&G announced it was abandoning the NND project. These concepts and terms included consideration to SCANA’s shareholders in the form of 70% Dominion Energy common stock and 30% cash, reflecting in total a premium of approximately 20% over the recent price of SCANA common stock, and an immediate rate credit for SCE&G’s customers, maintenance of rates related to the NND project at or below current levels, a reduced amortization period for SCANA’s investment in the NND project and a write-off of a portion of that investment. The transaction would involve expedited due diligence and would be subject to regulatory approval of the terms. At the end of the meeting, Mr. Marsh told Mr. Farrell and Mr. McGettrick that SCANA’s situation was very complex and involved a number of variables and considerations; however, Mr. Marsh also said that SCANA’s board and management would consider what Mr. Farrell and Mr. McGettrick had conveyed and get back to them.

On October 4, 2017, Mr. Marsh called Mr. Farrell and told him that he would be presenting what Dominion Energy had conveyed at the October 1, 2017 meeting to the SCANA board. Mr. Marsh reiterated to Mr. Farrell that SCANA’s present circumstances that had arisen out of the abandonment of the NND project were very complex and involved a number of variables and considerations.

Also on October 4, 2017, Mr. Marsh received a telephone call from the chief executive officer of Party A. The chief executive officer told Mr. Marsh that Party A had been separately approached about a potential purchase of Santee Cooper and wanted to discuss the potential for SCANA and Party A to also engage in a strategic transaction. The chief executive officer of Party A also asked that SCANA agree to exclusivity obligations to restrict SCANA from seeking or negotiating with other parties regarding a strategic transaction and indicated that Party A would be unwilling to make a proposal to SCANA at that time without such exclusivity terms. Mr. Marsh asked if there were any concepts or terms related to such a potential transaction involving SCANA that Party A was able to provide and the chief executive officer of Party A responded that Party A had no such concepts or terms to provide at that time, but that they were working on several ideas.

On October 6, 2017, a representative of Party C again indicated to Mr. Marsh in a meeting requested by the representative that Party C would be interested in talking to SCANA about a potential strategic transaction if

36

SCANA was interested in considering such a transaction, but the representative did not propose any concepts or terms that would apply to such a possible transaction or any process that would apply to the consideration of such a transaction.

An in-person meeting of the SCANA board was held on October 6, 2017. Members of SCANA’s senior management and representatives of Mayer Brown, Morgan Stanley and RBC Capital Markets attended this meeting. At this meeting, Mr. Marsh described for the SCANA board the recent discussions with each of Dominion Energy, Party A and Party C. The SCANA board, together with SCANA’s management, Morgan Stanley, RBC Capital Markets and Mayer Brown, then discussed whether it was prudent to commence a limited process to identify potential acquirors of SCANA at that time. After weighing the considerations involved and the consequences of commencing such a process, the SCANA board determined to move forward with exploring the possibility of a strategic transaction with Dominion Energy and with Party A, including providing due diligence information to each of Dominion Energy and Party A, and authorized SCANA’s management and advisors to proceed accordingly. After the representatives of Morgan Stanley and RBC Capital Markets were excused from the meeting, representatives of Mayer Brown summarized for the SCANA board the material terms proposed by Morgan Stanley and RBC Capital Markets regarding their respective engagements as a financial advisor to SCANA in connection with a possible strategic transaction.

After the conclusion of the meeting of the SCANA board on October 6, 2017, Mr. Marsh called Mr. Farrell to inform him of the SCANA board’s decision to proceed to explore a potential transaction with Dominion Energy (without any exclusivity obligations on SCANA) and called the chief executive officer of Party A to inform the chief executive officer of the SCANA board’s decision to proceed to explore a potential transaction with Party A (without any exclusivity obligations on SCANA).

On October 8, 2017, SCANA entered into a confidentiality agreement with Dominion Energy and a confidentiality agreement with Party A. Each of such confidentiality agreements contained standstill provisions which, among other things, restricted the ability of Dominion Energy and Party A to acquire or offer to acquire any SCANA securities and to submit any proposal or offer relating to a business combination with SCANA without the SCANA board’s prior written consent, except that the standstill restrictions would terminate (other than those relating to acquisitions of SCANA securities) in the event that SCANA announced it had entered into a definitive agreement relating to a strategic transaction. In connection with or prior to entering into such confidentiality agreements, each of Dominion Energy and Party A sought restrictions on SCANA’s ability to seek or negotiate with other parties regarding a possible strategic transaction, but SCANA did not agree to any such restrictions. Shortly thereafter, Dominion Energy and Party A were granted access to a data room and a due diligence process was commenced with Dominion Energy and with Party A.

On October 10, 2017, the chief executive officer of Party B called Mr. Marsh and indicated that Party B did not have any interest in acquiring an interest in the NND project but that Party B was willing to talk with SCANA about a potential strategic transaction if SCANA was considering strategic options. The chief executive officer of Party B did not propose any concepts or terms that would apply to such possible transaction or any process that would apply to the consideration of such a transaction.

Also, on October 10, 2017, Mr. Marsh, Mr. Addison and Jim O. Stuckey, SCANA’s Senior Vice President and General Counsel, met with the chief executive officer and other representatives of Party A in Columbia, South Carolina. At this meeting, the representatives of Party A conveyed some of the benefits and opportunities that might result from a potential strategic transaction between SCANA and Party A and indicated that a combination of Party A and SCANA would involve SCANA’s shareholders receiving solely the common stock of Party A in the transaction. The chief executive officer of Party A stated that Party A was not in the position at that time to indicate the amount of consideration SCANA’s shareholders would receive. The chief executive officer again requested that SCANA agree to exclusivity obligations restricting SCANA’s ability to seek or negotiate with other parties regarding a potential strategic transaction.

37

A telephonic meeting of the SCANA board was held on October 12, 2017. Members of SCANA’s senior management and representatives of Mayer Brown attended this meeting. At this meeting, Mr. Marsh described for the SCANA board the recent telephone call with Party B, recent meeting with Party A and recent communications from Dominion Energy indicating its desire to move forward with discussions expeditiously. Also, representatives of Mayer Brown summarized for the SCANA board certain matters related to the proposed engagements of Morgan Stanley and RBC Capital Markets as SCANA’s financial advisors, including the material proposed terms for such engagements and the disclosures made by Morgan Stanley and RBC Capital Markets with respect to their respective material relationships with Dominion Energy, Party A, Party B and Party C. In consultation with Mayer Brown, the SCANA board determined that none of such relationships of SCANA’s financial advisors were sufficiently material to adversely affect the ability of Morgan Stanley or RBC Capital Markets to act as financial advisors to SCANA in connection with a potential strategic transaction.

On October 13, 2017, the SCANA board, acting by written consent, approved the engagements of Morgan Stanley and RBC Capital Markets to serve as financial advisors to SCANA in connection with a possible strategic transaction and SCANA subsequently engaged each of Morgan Stanley and RBC Capital Markets.

Throughout October and November 2017, Dominion Energy conducted due diligence on SCANA and SCANA conducted reverse due diligence on Dominion Energy. However, no significant negotiation of terms of a potential strategic transaction between SCANA and Dominion Energy occurred during this time.

In mid-October 2017, Party A’s chief executive officer told Mr. Marsh that, in light of the considerable uncertainty resulting from SCE&G’s decision to abandon the NND project, including uncertainty regarding future electric rates, Party A was not able to narrow a valuation range for SCANA. Subsequent to this, Party A did not continue participation in the due diligence process and ceased to communicate interest in a potential strategic transaction with SCANA.

An in-person meeting of the SCANA board was held on October 24, 2017. Members of SCANA’s senior management and representatives of Mayer Brown attended this meeting. Among other things discussed at this meeting, the SCANA board discussed the status of discussions with Dominion Energy and Party A as well as the status of SCANA’s analysis of a potential strategic transaction more generally.

A telephonic meeting of the SCANA board was held on October 26, 2017. Members of SCANA’s senior management and representatives of Mayer Brown, Morgan Stanley and RBC Capital Markets attended this meeting. Mr. Marsh informed the SCANA board of developments with respect to SCANA’s consideration of a potential strategic transaction. Mr. Marsh explained that SCANA had primarily been focused on trying to reach a settlement on rates and other regulatory matters resulting from the decision to abandon the NND project and participating in legislative hearings related to the same and further discussions ensued among the directors, management and the advisors regarding the potential for a strategic transaction with Dominion Energy and regulatory and related matters. After discussion, the SCANA board concluded that it was prudent to continue to seek a rate settlement and also to continue discussions with Dominion Energy on a parallel path.

On October 31, 2017, SCANA announced that Mr. Marsh would retire as the chief executive officer of SCANA and SCE&G and that on January 1, 2018 Mr. Addison would become chief executive officer of SCANA and SCE&G, among other leadership changes.

On November 16, 2017, SCE&G publicly proposed a $4.8 billion comprehensive solution to outstanding rate and regulatory issues relating to the abandoned NND project. Based on the reaction from legislators and other stakeholders to the proposal, it quickly became clear that this proposal was not a viable solution to the rate and regulatory issues relating to the abandoned NND project.

During the week of November 20, 2017, Mr. McGettrick and Mr. Addison spoke on multiple occasions by telephone. Among other things discussed between Mr. McGettrick and Mr. Addison, Mr. McGettrick told

38

Mr. Addison that Dominion Energy was considering providing an updated proposal to SCANA regarding a potential strategic transaction.

On November 27, 2017, at the request of Mr. Farrell, Mr. Marsh, Mr. Addison and Mr. Hagood met with Mr. Farrell and Mr. McGettrick in Columbia, South Carolina. At this meeting, Mr. Farrell conveyed a proposal with respect to a potential strategic transaction between SCANA and Dominion Energy, which Mr. Farrell stated did not constitute an offer for a potential transaction. Key terms of this proposal included consideration to SCANA’s shareholders in the form of 75% to 80% Dominion Energy common stock and 20% to 25% cash, reflecting in total a premium of approximately 30% over the recent price of SCANA common stock, the retention of SCE&G’s headquarters in South Carolina and an updated plan for the regulatory resolution of the NND project which continued to include immediate cash refunds to SCE&G customers, prospective customer bill reductions for the NND project, a reduced amortization period for investments in the NND project, and a partial write-off of capital spent on the NND project. The representatives of SCANA told Mr. Farrell and Mr. McGettrick that the proposal would be shared with the SCANA board.

A telephonic meeting of the SCANA board was held on November 29, 2017. Members of SCANA’s senior management and representatives of Mayer Brown, Morgan Stanley and RBC Capital Markets attended this meeting. Mr. Addison summarized the terms of the proposal conveyed by Dominion Energy on November 27, 2017. Mr. Addison expressed his view that in light of the current issues, risks and challenges facing SCANA, the Dominion Energy proposal merited further consideration. Mr. Marsh agreed with that assessment. The SCANA board then unanimously concluded that the Dominion Energy proposal warranted further consideration and authorized SCANA’s management and advisors to pursue discussions with Dominion Energy accordingly.

On December 1, 2017, Mayer Brown provided to Dominion Energy an initial draft of a merger agreement with respect to a potential strategic transaction between SCANA and Dominion Energy. From this time until January 2, 2018, SCANA, Dominion Energy and their respective advisors, including McGuireWoods LLP, Dominion Energy’s outside legal counsel which we refer to as McGuireWoods, had extensive negotiations with respect to the terms of the proposed merger agreement.

On December 5, 2017, an in-person due diligence session was held in Richmond, Virginia between representatives of SCANA and representatives of Dominion Energy. Also on December 5, 2017, representatives of SCANA and Dominion Energy met to discuss the timeline for a potential transaction and the terms of Dominion’s proposal.

A telephonic meeting of the SCANA board was held on December 8, 2017. Members of SCANA’s senior management and representatives of Mayer Brown, Morgan Stanley and RBC Capital Markets attended this meeting, as did a representative of McNair Law Firm, P.A., SCANA’s South Carolina corporate counsel which we refer to as McNair. At this meeting, SCANA’s management discussed the due diligence Dominion Energy was conducting on SCANA, the status of Dominion Energy’s review of the proposed merger agreement, the proposed timeline for a potential transaction with Dominion Energy and the terms of Dominion Energy’s anticipated updated proposal. After that discussion, at the request of the SCANA board, the representatives of Morgan Stanley and RBC Capital Markets indicated that they were unaware of any material change in their respective institution’s material relationships disclosure previously provided to the SCANA board and that an updated material relationships disclosure would be provided before the next meeting of the SCANA board. Then, at the request of the SCANA board, each of Mayer Brown and McNair confirmed that their respective firms did not have a conflict of interest in representing SCANA in a transaction with Dominion Energy. SCANA’s financial advisors then provided an overview of, among other things, (a) Dominion Energy’s historical share price performance for the last three years, (b) Dominion Energy’s capital expenditures plan, key earnings drivers and master limited partnership structure as provided by Dominion Energy’s management, (c) certain financial projections provided by Dominion Energy’s management relating to Dominion Energy for fiscal years 2017 through 2022, and (d) based on publicly available information and the projections provided by Dominion Energy, Dominion Energy’s credit profile. Next, Iris N. Griffin, who was at that time the Vice President of Finance and

39

Treasurer of SCANA, made a presentation of SCANA’s forecasted earnings per share growth rates, which had been prepared by SCANA management, using various rate and regulatory settlement scenarios. Such scenarios did not take into account potential federal tax reform given the uncertainty with respect to such reform at that time. Following Ms. Griffin’s presentation, representatives of Mayer Brown provided the SCANA board an overview of the terms of the proposed merger agreement, including, among other things, a description of the structure of the transaction, the closing conditions of the parties, the obligations of the parties with respect to pursuing regulatory approvals and the terms restricting SCANA’s ability to solicit alternative transactions. At the end of the meeting, representatives of Mayer Brown reviewed with the members of the SCANA board their fiduciary duties under applicable law and asked the members of the SCANA board to provide updated information regarding past or current business or personal relationships with Dominion Energy or individuals associated with Dominion Energy in order to determine whether any potential conflicts of interest existed.

Also on December 8, 2017, McGuireWoods sent Mayer Brown a revised draft of the merger agreement that included, among other changes, a closing condition providing that the key terms related to the rate settlement would receive SCPSC approval with no deviation in terms from those proposed by Dominion Energy in connection with the merger.

On December 15, 2017, Dominion Energy provided SCANA with an updated proposal with respect to a potential strategic transaction between SCANA and Dominion Energy. This updated proposal reflected the due diligence that Dominion Energy had conducted on SCANA as well as the various discussions among the parties and their respective advisors to that point. Key terms of this updated proposal included: an all-stock, tax deferred transaction with a value of $54.50 per share of SCANA common stock (based on recent market prices of Dominion Energy common stock) reflecting an implied premium of approximately 27.9% over the closing price of SCANA common stock prior to a November 27, 2017 media report that SCANA had retained Morgan Stanley to explore strategic alternatives, various commitments by Dominion Energy to SCANA’s community including a commitment to maintain SCE&G’s headquarters in South Carolina, immediate cash refunds to customers totaling approximately $1.3 billion, which Dominion Energy estimated would result in an average refund of approximately $1,000 for residential customers, a 3.5% bill reduction related to the NND project going forward, a substantial write down of the investment in the NND project and exclusion from rate base of a gas-fired generation facility being acquired to help replace the NND project. The updated proposal also included certain requirements of Dominion Energy in order to proceed with the transaction, including that the key terms related to the rate settlement would receive SCPSC approval with no material changes in the terms of the rate settlement proposal and no change to the economic value of the rate settlement proposal and that, prior to the closing of the merger, there would be no changes in laws that impact SCANA, the BLRA or other utility laws.

An in-person meeting of the SCANA board was held on December 18, 2017. Members of SCANA’s senior management and representatives of Mayer Brown, Morgan Stanley, RBC Capital Markets and McNair attended this meeting. Also attending a portion of the meeting were representatives from SCANA’s various regulatory counsel in connection with the proposed transaction. After some introductory matters, the meeting commenced with regulatory counsel providing the SCANA board with an overview of the various regulatory clearances that would be needed in connection with the proposed transaction, including the likely timing for seeking and obtaining such clearances and the possibility of issues arising in obtaining such clearances. After regulatory counsel was excused from the meeting, representatives of Mayer Brown discussed with the SCANA board, as it had done in prior board meetings, information that the directors had provided regarding past or current business or personal relationships with Dominion Energy or individuals associated with Dominion Energy. After considering such relationships and in consultation with Mayer Brown, the SCANA board reaffirmed its prior determination that each director was independent and disinterested in connection with a potential strategic transaction with Dominion Energy. Mayer Brown also discussed with the SCANA board, as it had done in prior board meetings, the disclosures made by Morgan Stanley and RBC Capital Markets, which had been updated by Morgan Stanley and RBC Capital Markets prior to the meeting, with respect to their respective material relationships with Dominion Energy. After considering such relationships and in consultation with Mayer Brown, the SCANA board reaffirmed its prior determination that none of such relationships of SCANA’s financial

40

advisors were sufficiently material to adversely affect the ability of Morgan Stanley or RBC Capital Markets to act as financial advisors to SCANA in connection with a potential strategic transaction with Dominion Energy.

Next, Ms. Griffin made a presentation of SCANA’s financial projections, which had been prepared by SCANA’s management, using various rate and regulatory settlement scenarios. Such scenarios took into account the potential consequences of federal tax reform given the additional certainty with respect to such reform at that time. Then, each of Morgan Stanley and RBC Capital Markets discussed certain preliminary financial information relating to SCANA and the proposed transaction. Next, representatives of Mayer Brown, Morgan Stanley and RBC Capital Markets provided an update on the reverse due diligence that had been conducted on Dominion Energy and representatives of Mayer Brown summarized for the SCANA board certain key open issues in the merger agreement. The meeting concluded with Mr. Stuckey explaining to the SCANA board the terms of the change of control plans covering SCANA officers in the event a transaction was consummated.

On December 19, 2017, Mr. Addison had a meeting with an executive of Party C that had been arranged at the request of that executive. At that meeting, the executive indicated that Party C had a long-term interest in acquiring SCANA. The executive did not however propose any concepts or terms that would apply to a transaction between SCANA and Party C or any process that would apply to consideration of such a transaction. The executive also indicated that Party C would be interested in acquiring Public Service Company of North Carolina, a subsidiary of SCANA, for $2.2 billion. Mr. Addison informed the executive that he would present these matters to the SCANA board and would respond to the executive if and as directed by the SCANA board.

A telephonic meeting of the SCANA board was held on December 19, 2017. Members of SCANA’s senior management and representatives of Mayer Brown, Morgan Stanley, RBC Capital Markets and McNair attended this meeting. At this meeting, Mr. Addison reported on his recent meeting with an executive of Party C. Mr. Addison explained that, in his view, Party C’s proposal to acquire SCANA’s subsidiary, Public Service Company of North Carolina, was not particularly attractive given the valuation proposed by Party C and the fact that Public Service Company of North Carolina was a key driver of SCANA’s growth. The SCANA board concurred with this assessment. SCANA’s management and advisors then discussed with the SCANA board certain significant open issues with respect to the merger agreement with Dominion Energy, including the triggers for and amount of the reverse termination fee payable by Dominion Energy, certain deal protection terms, including the amount of the termination fee payable by SCANA, closing conditions relating to South Carolina regulatory approvals and changes that cannot be considered in determining whether a material adverse effect on SCANA has occurred. After discussion, the SCANA board provided SCANA’s management and advisors with guidance on these issues.

Later on December 19, 2017, SCANA, through its financial advisors, had a discussion with Dominion Energy regarding various potential methods to determine a mutually acceptable reference stock price for each party for calculating the fixed exchange ratio, as well as with respect to other open issues. SCANA’s proposed method for calculating the exchange ratio reflected a value of $57 per share of SCANA common stock.

On December 21, 2017, SCANA’s stock price declined approximately 9.5%. On the following day, SCANA’s stock price rose approximately 4.3%.

On December 22, 2017, McGuireWoods circulated a revised draft of the merger agreement on behalf of Dominion Energy. Among other changes, the revised draft reflected a closing condition that provided Dominion Energy the right not to close the transaction if after the signing of the merger agreement there were any changes to the BLRA or other South Carolina public utility laws and a termination fee amount of 3.5% of the equity value of the transaction for each of the termination fee payable by SCANA in certain instances and the termination fee payable by Dominion Energy in certain instances.

On December 27, 2017, Dominion Energy revised its proposal to, among other changes, increase the initial bill reduction to customers to at least 5% from the prior proposal of 3.5%. This increased benefit to customers

41

was attributed to Dominion Energy passing through to customers the benefits associated with the recently enacted reduction in federal income tax rates (estimated at the time to be at least 1.5%). Also on December 27, 2017, Dominion Energy proposed establishing the proposed transaction value through a fixed exchange ratio of 0.6620 of a share of Dominion Energy common stock for each outstanding share of SCANA common stock.

A telephonic meeting of the SCANA board was held on December 29, 2017. Members of SCANA’s senior management and representatives of Mayer Brown, Morgan Stanley, RBC Capital Markets, McNair and a representative of Womble Bond Dickinson, LLP, SCANA’s South Carolina regulatory counsel which we refer to as Womble Bond, attended this meeting. At this meeting, each of Morgan Stanley and RBC Capital Markets discussed with the SCANA board certain preliminary financial matters related to SCANA and the proposed transaction, including an update with respect to the negotiations on the exchange ratio. Following such discussion, Mr. Stuckey and representatives of Mayer Brown summarized the remaining significant open issues in the merger agreement and the representatives of Mayer Brown summarized the material terms of the merger agreement for the SCANA board. Among other material terms, Mayer Brown summarized the terms of the merger agreement relating to employee benefits and executive compensation, including treatment of equity and equity-based awards, post closing covenants relating to treatment of employees and employee benefits, including protection of severance benefits and the period of post-closing protection, and the proposed exceptions to the interim operating covenants, including salary increases, ordinary course equity grants, and retention bonuses. The representative of Womble Bond then summarized the material terms of the merger agreement relating to South Carolina regulatory matters and the rate settlement proposal.

Later on December 29, 2017, SCANA, through its financial advisors, conveyed a counterproposal to Dominion Energy with respect to the transaction consideration of an exchange ratio of 0.6690 of a share of Dominion Energy common stock for each outstanding share of SCANA common stock.

On December 30, 2017, Dominion Energy agreed to SCANA’s counterproposal on the proposed exchange ratio of 0.6690 of a share of Dominion Energy common stock for each outstanding share of SCANA common stock. On December 31, 2017, the parties also reached agreement on certain of the other significant open issues, including that the merger agreement would include a closing condition that provided Dominion Energy the right not to close the transaction if after the signing of the merger agreement there were any substantive changes to the BLRA or other South Carolina public utility laws that would have an adverse effect on SCANA and a termination fee in the amount of 3.0% of the offered equity value of the transaction for the termination fee payable by SCANA in certain instances and a termination fee in the amount of 3.5% of the offered equity value of the transaction for the termination fee payable by Dominion Energy in certain instances. Counsel for the parties then completed final documentation reflecting these agreements.

A telephonic meeting of the SCANA board was held on January 2, 2018. Members of SCANA’s senior management and representatives of Mayer Brown, Morgan Stanley, RBC Capital Markets and McNair attended this meeting. At this meeting, SCANA’s management and financial advisors provided the directors with an update of the final negotiations with respect to the exchange ratio and representatives of Mayer Brown summarized the resolution of the remaining significant open issues in the merger agreement. Then, Morgan Stanley and RBC Capital Markets separately provided the SCANA board with their respective financial analyses performed in connection with the proposed transaction. Next, Mr. Addison, Ms. Griffin, Mr. Stuckey and other members of SCANA management shared with the SCANA board their views on the merits of the proposed transaction with Dominion Energy and the alternatives to the transaction. Each member of management present at the meeting stated that, in his or her view, the proposed transaction with Dominion Energy was the best alternative available to SCANA under its present circumstances. The SCANA board then engaged in further discussions and deliberations, with the assistance of SCANA’s management and advisors, with respect to the proposed transaction with Dominion Energy.

Next, at the request of the SCANA board, Morgan Stanley rendered its oral opinion to the SCANA board (which was subsequently confirmed in writing by delivery of Morgan Stanley’s written opinion to the SCANA

42

board dated the same date) to the effect that, as of January 2, 2018, and based upon and subject to the assumptions made, procedures followed, matters considered and qualifications and limitations on the scope of review undertaken by Morgan Stanley as set forth in Morgan Stanley’s written opinion, the merger consideration (as such term is defined in the merger agreement) to be received by holders of SCANA common stock (other than certain excluded holders) pursuant to the merger agreement was fair from a financial point of view to such holders. Also at this meeting and at the request of the SCANA board, RBC Capital Markets rendered its oral opinion, confirmed by delivery of a written opinion dated January 2, 2018, to the SCANA board to the effect that, as of that date and based on and subject to the procedures followed, assumptions made, factors considered and qualifications and limitations described in the opinion, the merger consideration to be received by holders of SCANA common stock pursuant to the merger agreement was fair, from a financial point of view, to such holders. The full texts of the opinions of Morgan Stanley and RBC Capital Markets are attached as Annex B and Annex C, respectively, to this proxy statement/prospectus and set forth, among other things, the procedures followed, assumptions made, factors considered and qualifications and limitations on the review undertaken in connection with their respective opinions, as more fully described in the section entitled “—Opinions of SCANA’s Financial Advisors” beginning on page 48 of this proxy statement/prospectus.

The SCANA board then unanimously (a) determined that it is in the best interests of SCANA and the shareholders of SCANA that SCANA enter into the merger agreement and consummate the merger and the other transactions contemplated by the merger agreement on the terms and subject to the conditions set forth in the merger agreement, (b) adopted the merger agreement and approved the transactions contemplated by the merger agreement, including the merger, (c) directed that the approval of the merger agreement be submitted to a vote at a meeting of the shareholders of SCANA and (d) resolved to recommend that the shareholders of SCANA approve the merger agreement.

In the early evening of January 2, 2018, the parties executed the merger agreement.

In the early morning of January 3, 2018, SCANA and Dominion Energy issued a joint press release announcing the transaction.

SCANA’s Reasons for the Merger; Recommendation of the SCANA Board

SCANA’s Reasons for the Merger

At a meeting held on January 2, 2018, the SCANA board unanimously (i) determined that it is in the best interests of SCANA and the SCANA shareholders that SCANA enter into the merger agreement and complete the merger and the other transactions contemplated by the merger agreement on the terms and subject to the conditions set forth in the merger agreement, (ii) adopted the merger agreement and approved the transactions contemplated by the merger agreement, including the merger, (iii) directed that the approval of the merger agreement be submitted to a vote at a meeting of the SCANA shareholders, and (iv) resolved to recommend that the SCANA shareholders approve the merger agreement. In evaluating the merger, the SCANA board consulted with SCANA’s management and legal and financial advisors and, in reaching its unanimous decision to adopt the merger agreement and to recommend that the SCANA shareholders approve the merger agreement, considered numerous factors which are discussed below.

Among the information and material factors considered by the SCANA board were the following (not in any relative order of importance):

47

The foregoing discussion of the information and factors considered by the SCANA board is not intended to be exhaustive, but includes the material factors considered by the SCANA board. In view of the variety of factors considered in connection with its evaluation of the merger, the SCANA board did not find it practicable to, and did not, quantify or otherwise assign relative weights to the specific factors considered in reaching its determination and recommendation. In addition, individual directors may have given different weights to different factors. The SCANA board did not undertake to make any specific determination as to whether any factor, or any particular aspect of any factor, supported or did not support its ultimate determination. The SCANA board based its recommendation on the totality of the information presented.

Portions of this explanation of the reasons for the merger and other information presented in this section are forward-looking in nature and, therefore, should be read in light of the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 26 of this proxy statement/prospectus.

Recommendation of the SCANA Board

The SCANA board recommends that you vote “FOR” the merger proposal.

Opinions of SCANA’s Financial Advisors

Opinion of Morgan Stanley & Co. LLC

Morgan Stanley was retained by SCANA to act as its financial advisor in connection with the merger and to provide financial advice and assistance and, upon SCANA’s request, to render a financial opinion, in each case in connection therewith. The SCANA board selected Morgan Stanley to act as its financial advisor based on Morgan Stanley’s qualifications, expertise and reputation, its knowledge of and involvement in recent transactions in SCANA’s industry and its knowledge and understanding of the business and affairs of SCANA. On January 2, 2018, Morgan Stanley rendered its oral opinion, which was subsequently confirmed in writing, to the SCANA board to the effect that, as of that date, and based upon and subject to the assumptions made, procedures followed, matters considered and qualifications and limitations on the scope of review undertaken by Morgan Stanley as set forth in Morgan Stanley’s written opinion, the merger consideration to be received by the holders of shares of SCANA common stock (other than the holders of the cancelled shares) pursuant to the merger agreement was fair from a financial point of view to the holders of shares of SCANA common stock.

48

The full text of the written opinion of Morgan Stanley delivered to the SCANA board, dated January 2, 2018, is attached as Annex B and incorporated into this proxy statement/prospectus by reference in its entirety. The opinion sets forth, among other things, the assumptions made, procedures followed, matters considered and qualifications and limitations on the scope of the review undertaken by Morgan Stanley in rendering its opinion. SCANA shareholders are urged to, and should, read the opinion carefully and in its entirety. Morgan Stanley’s opinion is directed to the SCANA board and addresses only the fairness from a financial point of view of the merger consideration to be received by the holders of shares of SCANA common stock (other than the holders of the cancelled shares) pursuant to the merger agreement as of the date of the opinion. Morgan Stanley’s opinion did not address the relative merits of the transactions contemplated by the merger agreement as compared to other business or financial strategies that might be available to SCANA, nor did it address the underlying business decision of SCANA to enter into the merger agreement or proceed with any other transaction contemplated by the merger agreement. In addition, Morgan Stanley’s opinion did not in any manner address the prices at which shares of Dominion Energy common stock will trade following completion of the merger or at any time, and Morgan Stanley’s opinion was not intended to, and does not, express any opinion or recommendation as to how the holders of shares of SCANA common stock should vote at the special meeting. The summary of Morgan Stanley’s opinion set forth in this proxy statement/prospectus is qualified in its entirety by reference to the full text of Morgan Stanley’s opinion.

For purposes of rendering its opinion, Morgan Stanley, among other things:

49

In arriving at its opinion, Morgan Stanley assumed and relied upon, without independent verification, the accuracy and completeness of the information that was publicly available or supplied or otherwise made available to Morgan Stanley by SCANA and Dominion Energy, and formed a substantial basis for Morgan Stanley’s opinion. With respect to the SCANA management projections and the Dominion Energy management projections, Morgan Stanley assumed that they had been reasonably prepared on bases reflecting the best currently available estimates and judgments of the respective managements of SCANA and Dominion Energy of the future financial performance of SCANA and Dominion Energy. In addition, Morgan Stanley assumed that the merger will be completed in accordance with the terms set forth in the merger agreement without any waiver, amendment or delay of any terms or conditions, including, among other things, that the merger will be treated as a tax-free reorganization, pursuant to the Code. Morgan Stanley relied upon, without independent verification, the assessment by the management of SCANA of: (i) the timing and risks associated with the integration of SCANA and Dominion Energy and (ii) their ability to retain key employees of SCANA and Dominion Energy, respectively. Morgan Stanley assumed that in connection with the receipt of all the necessary governmental, regulatory or other approvals and consents required for the merger, no delays, limitations, conditions or restrictions will be imposed that would have a material adverse effect on the contemplated benefits expected to be derived in the merger (but Morgan Stanley assumed, without independent verification, the reasonableness of those delays, limitations, conditions and restrictions contained in the financial projections prepared by the managements of SCANA and Dominion Energy).

Morgan Stanley is not a legal, tax, or regulatory advisor. Morgan Stanley is a financial advisor only and has relied upon, without independent verification, the assessment of SCANA and its legal, tax, and regulatory advisors with respect to legal, tax, and regulatory matters. For purposes of its analysis Morgan Stanley did not make any assessment of the status of outstanding litigation or regulatory proceedings involving SCANA and excluded the effects of any such litigation or proceedings in its analysis, other than those effects included in the financial projections prepared by the managements of SCANA and Dominion Energy, upon which Morgan Stanley relied without independent verification. Morgan Stanley expresses no opinion with respect to the fairness of the amount or nature of the compensation to any of SCANA’s officers, directors or employees, or any class of such persons, relative to the merger consideration to be received by the holders of shares of SCANA common stock (other than the holders of the cancelled shares) in the merger. Morgan Stanley did not make any independent valuation or appraisal of the assets or liabilities of SCANA or Dominion Energy, nor was Morgan Stanley furnished with any such valuations or appraisals. Morgan Stanley’s opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to Morgan Stanley as of January 2, 2018. Events occurring after January 2, 2018 may affect Morgan Stanley’s opinion and the assumptions used in preparing it, and Morgan Stanley did not assume any obligation to update, revise or reaffirm its opinion.

In arriving at its opinion, Morgan Stanley was not authorized to solicit, and did not solicit, interest from any party with respect to the acquisition, business combination or other extraordinary transaction, involving SCANA. At the direction of the management and the SCANA board, Morgan Stanley did not negotiate with anyone other than Dominion Energy.

Summary of Morgan Stanley Financial Analyses

SCANA Financial Analysis

The following is a brief summary of the material financial analyses performed by Morgan Stanley in connection with the preparation of its opinion. The following summary is not a complete description of Morgan Stanley’s opinion or the financial analyses performed and factors considered by Morgan Stanley in connection with its opinion, nor does the order of analyses described represent the relative importance or weight given to those analyses. The financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses used by Morgan Stanley, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. The analyses listed in the tables and described below must be considered as a whole; considering any portion of such

50

analyses and of the factors, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying Morgan Stanley’s opinion. Furthermore, mathematical analysis, such as determining the mean, median or average, is not in itself a meaningful method of using the data referred to below. Except as otherwise noted below, all implied values per share of SCANA common stock included in Morgan Stanley’s presentation to the SCANA board, as described in this section, were rounded to the nearest $0.25.

In performing the financial analyses summarized below and arriving at its opinion, Morgan Stanley used and relied upon the financial forecasts under the 5% regulatory settlement scenario and 9.75% regulatory settlement scenario. For more information, please see the section entitled “—Certain Forecasts Prepared by SCANA’s Management” beginning on page 82 of this proxy statement/prospectus. In addition, Morgan Stanley analyzed certain financial projections based on Wall Street research reports, which we refer to as IBES. With respect to the financial forecasts under the 3.5% regulatory settlement scenario, the terms of the 3.5% regulatory settlement scenario had been publicly proposed by SCANA on November 16, 2017 and, based on the reaction from regulators and other constituencies to such proposal, it quickly became clear that the proposal, in the view of SCANA’s management and the SCANA board, was not an acceptable solution to the outstanding rate and regulatory issues relating to the abandoned NND project. Accordingly, SCANA directed Morgan Stanley not to use and rely upon the financial forecasts under the 3.5% regulatory settlement scenario for purposes of Morgan Stanley’s financial analyses and opinion and SCANA provided such financial forecasts to Morgan Stanley for informational reference purposes only.

Comparable Companies Analysis

Morgan Stanley performed a comparable companies analysis, which attempts to provide an implied value of a company by comparing it to similar companies that are publicly traded. Morgan Stanley reviewed and compared certain financial information, ratios and multiples relating to SCANA to corresponding financial information, ratios and multiples for publicly traded regulated electric and gas and electric-only utility companies that shared characteristics with SCANA to derive an implied valuation range for SCANA.

The companies included in the comparable companies analysis were:

The foregoing companies were chosen based on Morgan Stanley’s knowledge of the industry and because such companies have businesses that may be considered similar to SCANA’s. Although none of such companies are identical or directly comparable to SCANA, these companies are publicly traded companies with operations and/or other criteria, such as lines of business, markets, business risks, growth prospects, maturity of business and size and scale of business, that, for purposes of its analysis, Morgan Stanley considered similar to those of SCANA. The foregoing summary and underlying financial analyses involved complex considerations and judgments concerning differences in financial and operating characteristics and other factors that could affect the values of the companies to which SCANA was compared. In evaluating comparable companies, Morgan Stanley

51

made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, which are beyond the control of SCANA, including, among other things, the impact of regulatory changes, industry growth and the absence of any adverse material change in the financial condition and prospects of SCANA or the industry or in the financial markets in general.

In performing this analysis, Morgan Stanley used the financial forecasts under the 5% regulatory settlement scenario and the 9.75% regulatory settlement scenario and IBES to compare the financial information and multiples of market value of the companies included in the comparable companies analysis to the following metrics of SCANA:

Morgan Stanley did not compare SCANA’s stock price to its 2018 estimated EPS because of significant write-downs expected to be made by SCANA in 2018 that would cause SCANA’s earnings in 2018 to be unrepresentative. In addition, Morgan Stanley applied a discount of 1.5 multiple points to the multiples of stock price to estimated 2019 EPS for the comparable companies referred to above to reflect the long-term average (based on the past 10 years) next-twelve-month multiple discount at which SCANA common stock has traded as compared to the trading prices of the stock of such comparable companies (based on historical trading prices as a multiple of estimated next-twelve-month EPS) and the expected low rate of growth of dividends per share reflected in the SCANA management projections relative to peers. The range of multiples of stock price to estimated EPS for 2019 for the companies included in the comparable companies analysis based on a compilation of earnings estimates by selected equity research analysts (after giving effect to the 1.5 multiple point discount described above) is 14.0x to 18.0x.

Applying this range of multiples, Morgan Stanley derived a range of approximate implied equity values per share of SCANA common stock as follows:

These implied value ranges were compared to the value of the merger consideration of $54.23 (based on the merger consideration of 0.6690 of a share of Dominion Energy common stock per share of SCANA common stock and a Dominion Energy common stock per share price of $81.06, which was the closing price of Dominion Energy common stock as of December 29, 2017) and to the value of the merger consideration of $55.39 (based on the merger consideration of 0.6690 of a share of Dominion Energy common stock per share of SCANA common stock and a Dominion Energy common stock per share price of $82.80, which was the 30-day intraday volume weighted average price of Dominion Energy common stock as of December 29, 2017, as reported by Bloomberg).

Discounted Cash Flow Analysis

Morgan Stanley performed a discounted cash flow analysis of SCANA, which is designed to provide an implied value of a company by calculating the present value of the estimated future unlevered cash flows and

52

terminal year value based upon a price-to-earnings multiple applied to net income in the terminal year. Morgan Stanley calculated a range of implied equity values per share for SCANA common stock based on estimates of future cash flows for calendar years 2018 through 2022 and the terminal year (assuming, at the direction of SCANA’s management, that, with respect to the financial forecasts under the 5% regulatory settlement scenario, terminal year net income grew at 2.6%, the compound annual growth rate from 2018 through 2022 for SCANA’s net income in this scenario and, with respect to the financial forecasts under the 9.75% regulatory settlement scenario, terminal year net income grew at 1.0%, the compound annual growth rate from 2018 through 2022 for SCANA’s net income in this scenario).

Morgan Stanley used estimates from the financial forecasts under the 5% regulatory settlement scenario and the 9.75% regulatory settlement scenario for purposes of the discounted cash flow analysis, as more fully described below. In performing a discounted cash flow analysis of SCANA using estimates from the financial forecasts under the 5% regulatory settlement scenario and 9.75% regulatory settlement scenario, Morgan Stanley first calculated the estimated unlevered free cash flows of SCANA and then calculated a terminal value for SCANA common stock by applying a 13.5x to 15.0x range of price-to-earnings multiples to SCANA’s terminal year estimated net income per share. This terminal year price-to-earnings multiple range was derived from the ten-year average (for the ten-year period ending December 29, 2017) of stock price to the estimated next-twelve-month EPS multiples for the companies in the comparable companies analysis, and then applying the 1.5 multiple point discount, as described above with respect to the comparable companies analysis, to reflect the long-term average multiple discount at which SCANA’s stock price to EPS traded as compared to the price to earnings multiples of the comparable companies. In view of the expected low rate of growth of dividends per share reflected in the SCANA management projections relative to peers, Morgan Stanley, based on its professional judgment and experience, did not consider it appropriate to assume that SCANA’s stock would cease to trade at this 1.5 multiple point discount.

Unlevered free cash flows were calculated by tax-effecting earnings before interest and taxes and adding back the aggregate of depreciation and amortization, deferred taxes and other cash flow adjustments provided by management, including the change in working capital, less the sum of capital expenditures. The free cash flows and range of terminal values were then discounted to present value as of December 31, 2017 using discount rates ranging from 5.2% to 6.1%, which were chosen by Morgan Stanley based upon prevailing interest rates and Morgan Stanley’s judgment of the estimated range of SCANA’s weighted average cost of capital. This analysis indicated the following implied range of values per share of SCANA common stock:

These implied value ranges were compared to the value of the merger consideration of $54.23 (based on the merger consideration of 0.6690 of a share of Dominion Energy common stock per share of SCANA common stock and a Dominion Energy common stock per share price of $81.06, which was the closing price of Dominion Energy common stock as of December 29, 2017) and to the value of the merger consideration of $55.39 (based on the merger consideration of 0.6690 of a share of Dominion Energy common stock per share of SCANA common stock and a Dominion Energy common stock per share price of $82.80, which was the 30-day intraday volume weighted average price of Dominion Energy common stock as of December 29, 2017, as reported by Bloomberg).

Future Stock Price Analysis

Using estimates from the financial forecasts under the 5% regulatory settlement scenario and the 9.75% regulatory settlement scenario, Morgan Stanley performed an illustrative analysis of SCANA’s potential future stock price as compared to the merger consideration. This analysis compared (i) SCANA’s potential future stock

53

price for each of the years 2018 and 2019 based on SCANA’s standalone projected next-twelve month EPS using an illustrative price-to-EPS multiple range derived from historical trading analyses described below and based on Morgan Stanley’s professional judgment and experience to (ii) the value of the merger consideration of $54.23 (based on the merger consideration of 0.6690 of a share of Dominion Energy common stock per share of SCANA common stock and a Dominion Energy common stock per share price of $81.06, which was the closing price of Dominion Energy common stock as of December 29, 2017) and the value of the merger consideration of $55.39 (based on the merger consideration of 0.6690 of a share of Dominion Energy common stock per share of SCANA common stock and a Dominion Energy common stock per share price of $82.80, which was the 30-day intraday volume weighted average price of Dominion Energy common stock as of December 29, 2017, as reported by Bloomberg).

The illustrative price to EPS multiple range selected by Morgan Stanley in this analysis was derived from the following metrics based on the closing price of SCANA common stock as of December 29, 2017:

This analysis indicated that the potential future value per share of SCANA common stock in all of the ranges of potential future values calculated using each of the financial forecasts under the 5% regulatory settlement scenario and the 9.75% regulatory settlement scenario described above would be lower than the value of the merger consideration on a per-share basis as of December 29, 2017. Specifically, across the range of multiples analyzed, this analysis indicated the following high and low range of implied values per share of SCANA common stock:

Morgan Stanley also presented the median potential future value per share of SCANA common stock based on the ranges calculated in the analysis described above and discounted the median potential future values per share of SCANA common stock to present value using an 8.1% discount rate, which is the midpoint of SCANA’s cost of equity, selected by Morgan Stanley based on the application of its professional judgment and experience, inclusive of projected dividends per share over the applicable time period discounted to present value using the same discount rate. This analysis indicated the following implied discounted median values per share of SCANA common stock:

54

Reference Data

In addition to conducting the analyses described above, Morgan Stanley reviewed the following data, which was used for reference purposes only and not as a component of its fairness analysis.

Reference Discounted Cash Flow Analyses

For reference only and not as a component of its fairness analysis, Morgan Stanley performed additional discounted cash flow analyses of SCANA using the financial forecasts under the 3.5% regulatory settlement scenario and the 5% regulatory settlement scenario but, in each case, without applying the 1.5 multiple point discount mentioned above. Morgan Stanley calculated a range of implied equity values per share for SCANA common stock based on estimates of future cash flows for calendar years 2018 through 2022 and the terminal year (assuming at the direction of SCANA’s management, that, with respect to the 3.5 % Rate Reduction Scenario, terminal year net income grew at 3.1%, the compound annual growth rate from 2018 through 2022 for SCANA’s net income in this scenario and, with respect to the financial forecasts under the 5% regulatory settlement scenario, terminal year net income grew at 2.6%, the compound annual growth rate from 2018 to 2022 for SCANA’s net income in this scenario).

In performing a discounted cash flow analysis of SCANA using estimates from the financial forecasts under the 3.5% regulatory settlement scenario and the 5% regulatory settlement scenario, Morgan Stanley first calculated the estimated unlevered free cash flows of SCANA and then calculated a terminal value for SCANA common stock by applying a 15.0x to 16.5x range of price to earnings multiples to SCANA’s terminal year estimated net income. Although, as discussed above, Morgan Stanley, based on its professional judgment and experience, determined that application of the 1.5 multiple point discount was appropriate, it presented a discounted cash flow analysis using the financial forecasts under the 5% regulatory settlement scenario without applying such discount in order to illustrate for the SCANA board the potential impact on the implied range of values presented to the SCANA board if this historic multiple discount were considered not to be applicable in these scenarios. With respect to the discounted cash flow analysis using the financial forecasts under the 3.5% regulatory settlement scenario, Morgan Stanley did not apply the 1.5 multiple point discount because it concluded, based on its professional judgment and experience, that if the results projected by such scenario were achieved (despite the views of SCANA’s management and the SCANA board that the 3.5% regulatory settlement scenario was unlikely to be achieved, as noted above), it would be reasonable to expect that SCANA common stock could trade at a multiple more consistent with the trading multiples of comparable companies. The terminal year price-to-earnings multiple range was derived from the ten-year average (for the ten-year period ending December 29, 2017) of stock price to the estimated next-twelve-month EPS multiples for the companies in the comparable companies analysis.

Unlevered free cash flows were calculated by tax-effecting earnings before interest and taxes and adding back the aggregate of depreciation and amortization, deferred taxes and other cash flow adjustments provided by management including the change in working capital less the sum of capital expenditures. The free cash flows and range of terminal values were then discounted to present value as of December 31, 2017 using discount rates ranging from 5.2% to 6.1%, which were chosen by Morgan Stanley based upon prevailing interest rates and Morgan Stanley’s judgment of the estimated range of SCANA’s weighted average cost of capital. This analysis indicated the following implied range of values per share of SCANA common stock:

These implied value ranges were compared to the value of the merger consideration of $54.23 (based on the merger consideration of 0.6690 of a share of Dominion Energy common stock per share of SCANA common

55

stock and a Dominion Energy common stock per share price of $81.06, which was the closing price of Dominion Energy common stock as of December 29, 2017) and to the value of the merger consideration of $55.39 (based on the merger consideration of 0.6690 of a share of Dominion Energy common stock per share of SCANA common stock and a Dominion Energy common stock per share price of $82.80, which was the 30-day intraday volume weighted average price of Dominion Energy common stock as of December 29, 2017, as reported by Bloomberg).

Precedent Transactions Analysis

For reference only and not as a component of its fairness analysis, Morgan Stanley performed a precedent transactions analysis, which is designed to imply a value of a company based on publicly available financial information of selected transactions that share some characteristics with the merger.

Precedent Transaction Premiums. For reference only and not as a component of its fairness analysis, Morgan Stanley reviewed the premiums paid by acquirors in selected transactions in which regulated electric and gas and electric-only utilities were the target between January 1, 2014 and December 29, 2017, which was the last trading day prior to the date Morgan Stanley rendered its opinion, and that Morgan Stanley judged to be similar in certain respects to the merger or aspects thereof based on Morgan Stanley’s professional judgment and experience.

For each transaction included in this analysis, Morgan Stanley noted the implied premium to the target share price one day prior to announcement, except where the share price had been affected by pre-announcement events, in which case the unaffected target share price was used. The following is a list of the transactions reviewed:

Based on the foregoing results and Morgan Stanley’s professional judgment and experience, Morgan Stanley applied the range of premiums of 14.7% to 50.1% for the precedent transactions to the closing price of the shares of SCANA common stock of $39.78 as of December 29, 2017 to derive a range of implied equity values per share. The results of the analysis were as indicated in the following table:

This implied value range was compared to the value of the merger consideration of $54.23 (based on the merger consideration of 0.6690 of a share of Dominion Energy common stock per share of SCANA common stock and a Dominion Energy common stock per share price of $81.06, which was the closing price of Dominion Energy common stock as of December 29, 2017) and as compared to the value of the merger consideration of $55.39 (based on the merger consideration of 0.6690 of a share of Dominion Energy common stock per share of SCANA common stock and a Dominion Energy common stock per share price of $82.80, which was the 30-day intraday volume weighted average price of Dominion Energy common stock as of December 29, 2017, as reported by Bloomberg).

56

Precedent Transaction Multiples. For reference only and not as a component of its fairness analysis, Morgan Stanley observed the range of stock prices to estimated one-year-forward EPS multiples for each of the selected precedent transactions as 20.1x to 27.2x. Morgan Stanley applied these multiples to SCANA’s estimated 2019 EPS based on the financial forecasts under the 5% regulatory settlement scenario and 9.75% regulatory settlement scenario. Morgan Stanley then calculated implied equity value per share of SCANA common stock:

These implied value ranges were compared to the value of the merger consideration of $54.23 (based on the merger consideration of 0.6690 of a share of Dominion Energy common stock per share of SCANA common stock and a Dominion Energy common stock per share price of $81.06, which was the closing price of Dominion Energy common stock as of December 29, 2017) and as compared to the value of the merger consideration of $55.39 (based on the merger consideration of 0.6690 of a share of Dominion Energy common stock per share of SCANA common stock and a Dominion Energy common stock per share price of $82.80, which was the 30-day intraday volume weighted average price of Dominion Energy common stock as of December 29, 2017, as reported by Bloomberg).

No company or transaction utilized in the precedent transactions analysis is identical to SCANA or the merger, respectively. In evaluating the precedent transactions, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, market and financial conditions and other matters, which are beyond SCANA’s control, including, among other things, the impact of competition on SCANA’s business or the industry generally, regulatory changes, industry growth and the absence of any adverse material change in SCANA’s financial condition or the industry or in the financial markets in general, which could affect the aggregate value, equity value and premium paid of the transactions to which they are being compared.

Equity Research Analysts’ Price Targets. For reference only and not as a component of its fairness analysis, Morgan Stanley reviewed and analyzed the analyst price targets for SCANA common stock, of $38.50 to $60.00 as of December 29, 2017, which was the last trading day prior to the date Morgan Stanley rendered its opinion. Morgan Stanley then discounted the range of analyst price targets for SCANA common stock to present value using a 8.2% discount rate, which is the midpoint of SCANA’s cost of equity, selected by Morgan Stanley based on the application of its professional judgment and experience, which produced an implied equity value per share range of SCANA common stock of $35.50 to $55.50. The public market trading price targets published by equity research analysts do not necessarily reflect current market trading prices for SCANA common stock, and these estimates are subject to uncertainties.

Historical Trading Range. For reference only and not as a component of its fairness analysis, Morgan Stanley reviewed the historical trading range of shares of SCANA common stock for the last 6 months and the last 3 months, in each case ending on December 29, 2017, and observed a range of $37.50 to $69.75, for the last 6 months, and a range of $37.50 to $56.25, for the last 3 months.

Dominion Energy Common Stock

Morgan Stanley performed only limited financial analyses related to the value of Dominion Energy common stock, for reference only and not as a component of its fairness analysis. Morgan Stanley observed the trading performance of Dominion Energy common stock for the two-year period ended December 29, 2017 as well as the commentary from selected equity research analysts with respect to Dominion Energy common stock and the observed trading liquidity of Dominion Energy common stock as compared to the number of shares of Dominion Energy common stock to be issued in the merger. As noted above, Morgan Stanley also reviewed, for reference only and not as a component of its fairness analysis, the pro forma impact of the merger on Dominion Energy’s

57

earnings per share, cash flow, consolidated capitalization and certain financial ratios. After discussion of these factors with the SCANA board, Morgan Stanley was not requested to and did not perform additional financial analyses to assess the value of Dominion Energy common stock.

General

In connection with the review of the merger by the SCANA board, Morgan Stanley performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a financial opinion is a complex process and is not necessarily susceptible to a partial analysis or summary description. In arriving at its opinion, Morgan Stanley considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor it considered. Morgan Stanley believes that selecting any portion of its analyses, without considering all analyses as a whole, would create an incomplete view of the process underlying its analyses and opinion. In addition, Morgan Stanley may have given various analyses and factors more or less weight than other analyses and factors, and may have deemed various assumptions more or less probable than other assumptions. As a result, the ranges of valuations resulting from any particular analysis described above should not be taken to be Morgan Stanley’s view of the actual value of SCANA or Dominion Energy.

In performing its analyses, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, regulatory, economic, market and financial conditions and other matters, which are beyond the control of SCANA and Dominion Energy. These include, among other things, industry growth, and the absence of any adverse material change in the financial condition and prospects of SCANA, Dominion Energy and the industry, and in the financial markets in general. Any estimates contained in Morgan Stanley’s analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates.

Morgan Stanley conducted the analyses described above solely as part of its analysis of the fairness, from a financial point of view, of the merger consideration pursuant to the merger agreement to the SCANA shareholders (other than the holders of the cancelled shares), and in connection with the delivery of its opinion, dated January 2, 2018, to the SCANA board. Morgan Stanley’s opinion did not address any other aspect of the merger or related transactions. The merger consideration pursuant to the merger agreement was determined through arm’s-length negotiations between SCANA and Dominion Energy and the merger agreement was adopted by the SCANA board. Morgan Stanley acted as financial advisor to the SCANA board during these negotiations but did not, however, recommend any specific exchange ratio for purposes of determining the merger consideration to SCANA or the SCANA board, nor opine that any specific exchange ratio constituted the only appropriate exchange ratio for the merger.

Morgan Stanley’s opinion and its presentation to the SCANA board was one of many factors taken into consideration by the SCANA board in deciding to adopt the merger agreement and approve the transactions contemplated thereby and to recommend the approval of the merger agreement by the SCANA shareholders. Consequently, the analyses as described above should not be viewed as determinative of the opinion of the SCANA board with respect to the merger consideration pursuant to the merger agreement or of whether the SCANA board would have been willing to agree to a different merger consideration. Morgan Stanley’s opinion was approved by a committee of Morgan Stanley investment banking and other professionals in accordance with its customary practice.

SCANA retained Morgan Stanley based on Morgan Stanley’s qualifications, experience and expertise and its familiarity with SCANA. Morgan Stanley is a global financial services firm engaged in the securities, investment management and individual wealth management businesses. Its securities business is engaged in securities underwriting, trading and brokerage activities, foreign exchange, commodities and derivatives trading, and prime brokerage, as well as providing investment banking, financing and financial advisory services. Morgan Stanley, its affiliates, directors and officers may at any time invest on a principal basis or manage funds that invest, hold long or short positions, finance positions, and may trade or otherwise structure and effect

58

transactions, for their own account or the accounts of its customers, in debt or equity securities or loans of SCANA, Dominion Energy or any other company, or any currency or commodity, that may be involved in the merger, or any related derivative instrument.

Under the terms of its engagement letter dated October 18, 2017, Morgan Stanley provided SCANA financial advisory services and a financial opinion, described in this section and attached to this proxy statement/prospectus as Annex B, in connection with the merger, and SCANA has agreed to pay Morgan Stanley a fee of approximately $27 million for its financial advisory services, $5 million of which was paid upon delivery of Morgan Stanley’s opinion, 25% of which is contingent upon SCANA shareholder approval of the merger proposal and the remainder of which is contingent upon closing of the merger. In addition, SCANA may, in its sole discretion, pay Morgan Stanley an incremental incentive fee to be paid upon closing of the merger. SCANA has also agreed to reimburse Morgan Stanley for its reasonable out-of-pocket expenses incurred from time to time in connection with this engagement. In addition, SCANA has agreed to indemnify Morgan Stanley and its affiliates, its and their respective officers, directors, employees and agents and each other person, if any, controlling Morgan Stanley or any of its affiliates, against any losses, claims, damages or liabilities, relating to, arising out of or in connection with Morgan Stanley’s engagement and to reimburse certain expenses relating to such indemnity.

In the two years prior to the date of its opinion, Morgan Stanley has provided financial advisory and financing services for SCANA and has received fees in connection with such services in the range of $0 to $1 million. In addition, in the two years prior to the date of its opinion, Morgan Stanley has provided financing services to Dominion Energy and has received fees in connection with such services in the range of $10 million to $11 million. Morgan Stanley may also seek to provide financial advisory and financing services to SCANA, Dominion Energy and their respective affiliates in the future and would expect to receive fees for the rendering of these services.

Opinion of RBC Capital Markets, LLC

SCANA engaged RBC Capital Markets as a financial advisor in connection with the merger. As part of this engagement, the SCANA board requested that RBC Capital Markets evaluate the fairness, from a financial point of view, of the merger consideration to be received by holders of SCANA common stock pursuant to the merger agreement. At a January 2, 2018 meeting of the SCANA board held to evaluate the merger, RBC Capital Markets rendered an oral opinion, confirmed by delivery of a written opinion dated January 2, 2018, to the SCANA board to the effect that, as of that date and based on and subject to the procedures followed, assumptions made, factors considered and qualifications and limitations described in the opinion, the merger consideration to be received by holders of SCANA common stock pursuant to the merger agreement was fair, from a financial point of view, to such holders. The full text of RBC Capital Markets’ written opinion, dated January 2, 2018, which is attached as Annex C to this proxy statement/prospectus and incorporated in this document by reference, sets forth, among other things, the procedures followed, assumptions made, factors considered and qualifications and limitations on the review undertaken by RBC Capital Markets in connection with its opinion, as more fully described in this section. The following summary of RBC Capital Markets’ opinion is qualified in its entirety by reference to the full text of the opinion. RBC Capital Markets delivered its opinion to the SCANA board for the benefit, information and assistance of the SCANA board (in its capacity as such) in connection with of its evaluation of the merger. RBC Capital Markets’ opinion addressed only the fairness, from a financial point of view and as of the date of such opinion, of the merger consideration (to the extent expressly specified in such opinion) and did not address any other aspect of the merger. RBC Capital Markets’ opinion also did not address the underlying business decision of SCANA to engage in the merger or the relative merits of the merger compared to any alternative business strategy or transaction that might be available to SCANA or in which SCANA might engage. RBC Capital Markets does not express any opinion and does not make any recommendation to any shareholder as to how such shareholder should vote or act with respect to the merger or any proposal to be voted upon in connection with the merger or otherwise.

59

For purposes of rendering its opinion, RBC Capital Markets undertook such review, inquiries and analyses as it deemed necessary or appropriate under the circumstances and, among other things:

In rendering its opinion, RBC Capital Markets assumed and relied upon the accuracy and completeness of all information that was reviewed by RBC Capital Markets, including all financial, legal, tax, accounting, operating and other information provided to or discussed with RBC Capital Markets by or on behalf of SCANA or Dominion Energy (including, without limitation, financial statements and related notes), and upon the assurances of the respective managements and other representatives of SCANA and Dominion Energy that they were not aware of any relevant information that was omitted or that remained undisclosed to RBC Capital Markets. RBC Capital Markets did not assume responsibility for independently verifying and it did not independently verify such information. RBC Capital Markets also assumed that the financial projections and other estimates and data (including potential tax attributes relating to SCANA) that RBC Capital Markets was directed to utilize in its analyses were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the respective managements of SCANA and Dominion Energy, as the case may be, as to the future financial performance of, and were a reasonable basis upon which to evaluate, SCANA under the alternative regulatory settlement cases reflected therein, Dominion Energy, the potential pro forma effects of the merger and the other matters covered thereby. RBC Capital Markets expressed no opinion as to any such financial projections and other estimates and data or the assumptions upon which they were based. RBC Capital Markets relied upon the assessments of the managements of SCANA and Dominion Energy as to, among other things, (i) the potential impact on SCANA and Dominion Energy of market, competitive, seasonal, and other trends and developments in and prospects for, and governmental, regulatory and legislative matters relating to or otherwise affecting, the utility, power and energy industries and the sectors of such industries and geographic regions in which SCANA and Dominion Energy operate (including, without limitation, with respect to future commodity prices and availability, which are subject to significant volatility, existing, planned and/or abandoned infrastructure and other capital projects, including the construction and abandonment of the NND project, and pending and future rate cases, cost recovery and other regulatory proceedings and determinations) and assumptions of the managements of SCANA and Dominion Energy, respectively, as to such matters which,

60

if different than as provided to RBC Capital Markets, could have a meaningful impact on RBC Capital Markets’ analyses or opinion, (ii) existing and future relationships, agreements and arrangements with, and the ability to attract, retain and/or replace, key employees, customers, suppliers, contractors and subcontractors and other commercial relationships of SCANA and Dominion Energy, and (iii) the ability to integrate the operations of SCANA and Dominion Energy. RBC Capital Markets assumed that there would be no developments with respect to any of the foregoing that would have an adverse effect on SCANA, Dominion Energy or the merger or that otherwise would be meaningful in any respect to its analyses or opinion.

In connection with its opinion, RBC Capital Markets did not assume any responsibility to perform, and it did not perform, an independent valuation or appraisal of any of the assets or liabilities (contingent, off-balance sheet, accrued, derivative or otherwise) of or relating to SCANA, Dominion Energy or any other entity and RBC Capital Markets was not furnished with any such valuations or appraisals. RBC Capital Markets expressed no view or opinion as to the potential impact on SCANA, Dominion Energy or any other entity of any pending or potential litigation, claims or governmental, regulatory or other proceedings or investigations. RBC Capital Markets did not assume any obligation to conduct, and it did not conduct, any physical inspection of the properties or facilities of SCANA, Dominion Energy or any other entity. RBC Capital Markets did not evaluate the solvency or fair value of SCANA, Dominion Energy or any other entity under any state, federal or other laws relating to bankruptcy, insolvency or similar matters. RBC Capital Markets assumed that the merger would be completed in accordance with the terms of the merger agreement and in compliance with all applicable laws, documents and other requirements, without waiver, modification or amendment of any material term, condition or agreement, and that, in the course of obtaining the necessary governmental, regulatory or third-party approvals, consents, releases, waivers and agreements for the merger, no delay, limitation, restriction or condition would be imposed or occur, including any divestiture or other requirements, that would have an adverse effect on SCANA, Dominion Energy or the merger or that otherwise would be meaningful in any respect to its analyses or opinion. RBC Capital Markets also assumed that the merger would qualify as a reorganization within the meaning of Section 368(a) of the Code for U.S. federal income tax purposes. In addition, RBC Capital Markets assumed that the final executed merger agreement would not differ, in any respect meaningful to its analyses or opinion, from the draft that RBC Capital Markets reviewed.

RBC Capital Markets’ opinion spoke only as of the date of the opinion, was based on conditions as they existed and information supplied or reviewed as of the date of the opinion, and was without regard to any market, economic, financial, legal, regulatory or other circumstances or event of any kind or nature which may exist or occur after such date. RBC Capital Markets did not undertake and has no obligation to reaffirm, revise or update its opinion or otherwise comment upon events occurring after the date of its opinion with respect to its opinion. RBC Capital Markets did not express any opinion as to the actual value of Dominion Energy common stock when issued in connection with the merger or the price or range of prices at which SCANA common stock, Dominion Energy common stock or any other securities of SCANA or Dominion Energy may trade or otherwise be transferable at any time, including following announcement or completion of the merger. As the SCANA board was aware, the credit, financial and stock markets, and the industries in which SCANA and Dominion Energy operate, have experienced and continue to experience volatility and RBC Capital Markets expressed no opinion or view as to any potential effects of such volatility on SCANA or Dominion Energy (or their respective businesses) or the merger.

RBC Capital Markets’ opinion addressed the fairness, from a financial point of view and as of the date of the opinion, of the merger consideration (to the extent expressly specified in the opinion), without regard to individual circumstances of specific holders that may distinguish such holders or the securities of SCANA held by such holders. RBC Capital Markets’ opinion did not in any way address any other terms, conditions, implications or other aspects of the merger or the merger agreement, including, without limitation, the form or structure of the merger, or any other agreement, arrangement or understanding to be entered into in connection with or contemplated by the merger or otherwise. RBC Capital Markets did not express any opinion or view with respect to, and RBC Capital Markets relied upon the assessments of SCANA and SCANA’s representatives regarding, legal, regulatory, tax, accounting and similar matters (including changes resulting from, and the

61

impact of, the recent U.S. tax reform), as to which RBC Capital Markets understood that SCANA obtained such advice as SCANA deemed necessary from qualified professionals. Further, in rendering its opinion, RBC Capital Markets did not express any view on, and its opinion did not address, the fairness of the amount or nature of the compensation (if any) or other consideration to any officers, directors or employees of any party, or class of such persons, relative to the merger consideration or otherwise. In connection with its engagement, RBC Capital Markets was not requested to, and it did not, undertake a third-party solicitation process on SCANA’s behalf with respect to the acquisition of all or a part of SCANA. The issuance of RBC Capital Markets’ opinion was approved by RBC Capital Markets’ fairness opinion committee.

In preparing its opinion to the SCANA board, RBC Capital Markets performed various financial and comparative analyses, including those described below. The summary below of RBC Capital Markets’ material financial analyses provided to the SCANA board in connection with RBC Capital Markets’ opinion is not a comprehensive description of all analyses undertaken or factors considered by RBC Capital Markets in connection with its opinion. The preparation of a financial opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a financial opinion is not readily susceptible to partial analysis or summary description.

In arriving at its opinion, RBC Capital Markets employed several analytical methodologies and no one method of analysis should be regarded as critical to the overall conclusion reached by RBC Capital Markets. Each analytical technique has inherent strengths and weaknesses, and the nature of the available information may further affect the value of particular techniques. The overall conclusion reached by RBC Capital Markets was based on all analyses and factors presented, taken as a whole, and also on application of RBC Capital Markets’ experience and judgment. Such conclusion may have involved significant elements of subjective judgment and qualitative analysis and no opinion was given as to the value or merit standing alone of any one or more portions of such analyses or factors.

In performing its analyses, RBC Capital Markets considered industry performance, general business and economic conditions and other matters, many of which are beyond the control of SCANA and Dominion Energy. The estimates of the future performance of SCANA and Dominion Energy in or underlying RBC Capital Markets’ analyses are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than those estimates or those suggested by RBC Capital Markets’ analyses. The analyses do not purport to be appraisals or to reflect the prices at which a company or business might actually be sold or acquired or the prices at which any securities have traded or may trade at any time in the future. Accordingly, the estimates used in, and the implied reference ranges resulting from, any particular analysis described below are inherently subject to substantial uncertainty and should not be taken as RBC Capital Markets’ view of the actual value of SCANA or Dominion Energy.

The merger consideration was determined through negotiations between SCANA and Dominion Energy and the decision of SCANA to enter into the merger agreement was solely that of the SCANA board. RBC Capital Markets’ opinion and analyses were only one of many factors considered by the SCANA board in its evaluation of the merger and should not be viewed as determinative of the views of the SCANA board, SCANA’s management or any other party with respect to the merger or the merger consideration to be received by holders of SCANA common stock pursuant to the merger agreement.

Financial Analyses

The summary of the financial analyses described below under this heading “—Financial Analyses” is a summary of the material financial analyses provided by RBC Capital Markets to the SCANA board in connection with RBC Capital Markets’ opinion, dated January 2, 2018. The financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses performed by RBC Capital Markets, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Selecting portions of RBC Capital Markets’

62

financial analyses or factors considered or focusing on the data set forth in the tables below without considering all analyses or factors or the full narrative description of such analyses or factors, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of RBC Capital Markets’ financial analyses. In RBC Capital Markets’ opinion, the term merger consideration is defined as the implied per share value payable in the merger utilizing the 0.6690 exchange ratio and, for purposes of RBC Capital Markets’ financial analyses described below performed in connection with such opinion, the implied value was $54.23 per share based on the 0.6690 exchange ratio and the closing price of Dominion Energy common stock on December 29, 2017 (the last trading day prior to the date of RBC Capital Markets’ opinion to the SCANA board), which implied per share amount is referred to below as the implied per share merger consideration. Financial data utilized for SCANA in the financial analyses described below, to the extent based on internal financial forecasts and estimates of SCANA’s management, were based on two potential alternative regulatory settlement cases, referred to individually as the 5% regulatory settlement case and the 9.75% regulatory settlement case, respectively, and collectively as the SCANA forecasts, that SCANA directed RBC Capital Markets to use and rely upon for purposes of its analyses and opinion. Financial data utilized for Dominion Energy in the financial analyses described below, to the extent based on internal financial forecasts and estimates of Dominion Energy’s management, were based on financial forecasts and other information and data relating to Dominion Energy provided to or discussed with RBC Capital Markets by the management of Dominion Energy, which we refer to as the Dominion Energy forecasts.

SCANA Financial Analyses

Selected Public Companies Analysis. RBC Capital Markets performed a selected public companies analysis in which RBC Capital Markets reviewed certain financial and stock market information of SCANA and the following nine selected companies that RBC Capital Markets considered generally relevant as publicly traded companies with predominantly regulated integrated utility operations and over $5 billion in market capitalization, which we collectively refer to as the SCANA selected companies:

In its selected public companies analysis of SCANA, RBC Capital Markets reviewed, among other things, closing stock prices on December 29, 2017 as a multiple of calendar year 2019 estimated earnings per share, which we refer to as EPS. Financial data of the SCANA selected companies was based on publicly available research analysts’ estimates and other publicly available information. Financial data of SCANA was based on publicly available research analysts’ estimates, other publicly available information and the SCANA forecasts.

63

The overall low to high calendar year 2019 estimated EPS multiples observed for the SCANA selected companies were 15.4x to 19.2x (with a mean of 18.0x and a median of 18.5x). RBC Capital Markets also observed that the calendar year 2019 estimated EPS multiple for SCANA was 13.3x (based on publicly available research analysts’ estimates). RBC Capital Markets then applied a selected range of calendar year 2019 estimated EPS multiples of 13.3x to 18.5x to corresponding data of SCANA based on the SCANA forecasts. This analysis indicated the following approximate implied per share equity value reference ranges for SCANA based on the 5% regulatory settlement case and the 9.75% regulatory settlement case, respectively, as compared to the implied per share merger consideration:

No company used in this analysis is identical to SCANA. Accordingly, an evaluation of the results of this analysis is not entirely mathematical. Rather, this analysis involves complex considerations and judgments concerning differences in financial and operating characteristics and other factors that could affect the public trading or other values of the companies to which SCANA was compared.

Discounted Cash Flow Analysis. RBC Capital Markets performed a discounted cash flow analysis of SCANA by calculating the estimated present values of the standalone unlevered, after-tax free cash flows that SCANA was forecasted to generate during the fiscal years ending December 31, 2018 through December 31, 2021 based on the SCANA forecasts. RBC Capital Markets calculated terminal values for SCANA at the end of 2021 by applying to the terminal year 2022 estimated net income of SCANA a selected range of one-year forward EPS multiples of 14.2x to 16.9x. The unlevered, after-tax free cash flows and terminal values were then discounted to present value (as of December 31, 2017) using a selected discount rate range of 5.10% to 6.10%. This analysis indicated the following approximate implied per share equity value reference ranges for SCANA based on the 5% regulatory settlement case and the 9.75% regulatory settlement case, respectively, as compared to the implied per share merger consideration:

Dominion Energy Financial Analysis

Selected Public Companies Analysis. RBC Capital Markets performed a selected public companies analysis in which RBC Capital Markets reviewed certain financial and stock market information of Dominion Energy and the following five selected companies that RBC Capital Markets considered generally relevant as publicly traded diversified, integrated utilities with over $10 billion in market capitalization, which we collectively refer to as the Dominion Energy selected companies:

In its selected public companies analysis of Dominion Energy, RBC Capital Markets reviewed, among other things, closing stock prices on December 29, 2017 as a multiple of calendar years 2018 and 2019 estimated EPS. Financial data of the Dominion Energy selected companies was based on publicly available research analysts’ estimates and other publicly available information. Financial data of Dominion Energy was based on publicly available information and the Dominion Energy forecasts.

64

The overall low to high calendar year 2018 estimated EPS and calendar year 2019 estimated EPS multiples observed for the Dominion Energy selected companies were 19.3x to 21.5x (with a mean of 20.2x and a median of 19.8x) and 16.1x to 20.1x (with a mean of 18.5x and a median of 18.7x), respectively. RBC Capital Markets also observed that the calendar year 2018 estimated EPS and calendar year 2019 estimated EPS multiples for Dominion Energy were 20.1x and 19.0x, respectively (based on publicly available research analysts’ estimates). RBC Capital Markets then applied selected ranges of calendar year 2018 estimated EPS and calendar year 2019 estimated EPS multiples of 19.3x to 21.5x and 16.1x to 20.1x, respectively, to corresponding data of Dominion Energy based on the Dominion Energy forecasts. This analysis indicated the following approximate implied per share equity value reference ranges for Dominion Energy, as compared to the per share closing price of Dominion Energy common stock on December 29, 2017:

No company used in this analysis is identical to Dominion Energy. Accordingly, an evaluation of the results of this analysis is not entirely mathematical. Rather, this analysis involves complex considerations and judgments concerning differences in financial and operating characteristics and other factors that could affect the public trading or other values of the companies to which Dominion Energy was compared.

Certain Additional Information

RBC Capital Markets observed certain factors that were not considered part of RBC Capital Markets’ financial analyses with respect to its opinion but were referenced for informational purposes, including, among other things, the following:

Miscellaneous

SCANA has agreed to pay RBC Capital Markets for its services as a financial advisor an aggregate fee estimated to be approximately $14 million, of which $5 million was payable upon delivery of RBC Capital Markets’ opinion, 25% is payable upon receipt of approval of the merger by SCANA shareholders and the balance is contingent upon completion of the merger. RBC Capital Markets also may be entitled to an incremental incentive fee (the amount of which has not yet been determined) payable, in SCANA’s sole discretion, upon completion of the merger. SCANA also has agreed to reimburse RBC Capital Markets for expenses incurred in connection with RBC Capital Markets’ services and to indemnify RBC Capital Markets and related persons against certain liabilities arising out of RBC Capital Markets’ engagement.

As the SCANA board was aware, RBC Capital Markets and certain of its affiliates in the past have provided, currently are providing and in the future may provide investment banking and commercial banking services to SCANA and/or its affiliates unrelated to the merger, for which services RBC Capital Markets and its affiliates have received and expect to receive customary compensation, including, during the two-year period

65

prior to the date of RBC Capital Markets’ opinion, having acted or acting as a lender under certain credit facilities of SCANA. During such two-year period, RBC Capital Markets and such affiliates received aggregate fees for such commercial banking services described above of approximately $0.5 million from SCANA. As the SCANA board also was aware, RBC Capital Markets and certain of its affiliates in the past have provided, currently are providing and in the future may provide investment banking and commercial banking services to Dominion Energy and/or its affiliates, for which services RBC Capital Markets and its affiliates have received or expect to receive customary compensation, including, during the two-year period prior to the date of RBC Capital Markets’ opinion, having acted or acting as (i) joint lead manager or joint book-running manager for certain debt and equity offerings of Dominion Energy and certain of its affiliates in 2016 and 2017 and (ii) joint lead arranger for, and as a lender under, certain bridge and other credit facilities of Dominion Energy and certain of its affiliates. During such two-year period, RBC Capital Markets and such affiliates received aggregate fees for such investment banking and commercial banking services of approximately $24 million from Dominion Energy and certain of its affiliates.

RBC Capital Markets, as part of its investment banking services, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, corporate restructurings, underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. In the ordinary course of business, RBC Capital Markets and/or certain of its

affiliates may act as a market maker and broker in the publicly traded securities of SCANA, Dominion Energy and/or other entities involved in the merger or their respective affiliates and receive customary compensation in connection therewith, and may also actively trade securities of SCANA, Dominion Energy and/or other entities involved in the merger or their respective affiliates for RBC Capital Markets’ or its affiliates’ account or for the account of customers and, accordingly, RBC Capital Markets and its affiliates may hold a long or short position in such securities.

RBC Capital Markets is an internationally recognized investment banking firm which is regularly engaged in providing financial advisory services in connection with mergers and acquisitions. SCANA selected RBC Capital Markets as SCANA’s financial advisor in connection with the merger on the basis of RBC Capital Markets’ experience in similar transactions, reputation in the investment community and familiarity with SCANA and its business.

Directors and Management of Dominion Energy After the Merger

Upon completion of the merger, the board of directors and executive officers of Dominion Energy are expected to remain unchanged. Pursuant to the terms of the merger agreement, as soon as practical after completion of the merger, the Dominion Energy board intends to appoint a mutually agreeable current member of the SCANA board or SCANA’s executive management to serve on the Dominion Energy board. For information on Dominion Energy’s current directors and executive officers, please see Dominion Energy’s proxy statement dated March 23, 2018 and its Annual Report on Form 10-K for the year ended December 31, 2017. See the section entitled “Where You Can Find More Information” beginning on page  141 of this proxy statement/prospectus.

U.S. Federal Income Tax Consequences of the Merger

The following is a general discussion of the U.S. federal income tax consequences of the merger to “U.S. holders” (as defined below) of SCANA common stock that receive shares of Dominion Energy common stock in exchange for their shares of SCANA common stock in the merger. The following discussion is based upon the Code, the U.S. Treasury regulations promulgated thereunder and judicial and administrative authorities, rulings and decisions, all as in effect as of the date of this proxy statement/prospectus. These authorities may change, possibly with retroactive effect, and any such change could affect the accuracy of the statements and conclusions set forth in this discussion. This discussion does not address any tax consequences arising under the unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010, nor does it address any tax consequences arising under the laws of any state, local or foreign jurisdiction, or under any U.S. federal laws other than those pertaining to the income tax.

66

The following discussion applies only to U.S. holders of shares of SCANA common stock who hold such shares as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment). Further, this discussion does not purport to consider all aspects of U.S. federal income taxation that might be relevant to U.S. holders in light of their particular circumstances and does not apply to U.S. holders subject to special treatment under the U.S. federal income tax laws (such as, for example, dealers or brokers in securities, commodities or foreign currencies, traders in securities that elect to apply a mark-to-market method of accounting, banks and certain other financial institutions, insurance companies, mutual funds, tax-exempt organizations, holders subject to the alternative minimum tax provisions of the Code, partnerships, S corporations or other pass-through entities or investors in partnerships, regulated investment companies, real estate investment trusts, controlled foreign corporations, passive foreign investment companies, former citizens or residents of the United States, U.S. expatriates, holders whose functional currency is not the U.S. dollar, holders who hold shares of SCANA common stock as part of a hedge, straddle, constructive sale or conversion transaction or other integrated investment, holders who acquired SCANA common stock pursuant to the exercise of employee stock options, through a tax qualified retirement plan or otherwise as compensation or holders who actually or constructively own more than 5% of SCANA common stock).

For purposes of this discussion, the term “U.S. holder” means a beneficial owner of SCANA common stock that is for U.S. federal income tax purposes (i) an individual citizen or resident of the United States, (ii) a corporation, or entity treated as a corporation for U.S. federal income tax purposes, organized in or under the laws of the United States or any state thereof or the District of Columbia, (iii) a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) such trust has made a valid election to be treated as a U.S. person for U.S. federal income tax purposes or (iv) an estate, the income of which is includible in gross income for U.S. federal income tax purposes, regardless of its source.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds SCANA common stock, the tax treatment of a partner in such partnership generally will depend on the status of the partner and the activities of the partnership. Any entity treated as a partnership for U.S. federal income tax purposes that holds SCANA common stock, and any partners in such partnership, should consult their own independent tax advisors regarding the tax consequences of the merger to their specific circumstances.

Determining the actual tax consequences of the merger to you may be complex and will depend on your specific situation and on factors that are not within our control. You should consult your own independent tax advisor as to the specific tax consequences of the merger in your particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local, foreign and other tax laws and of changes in those laws.

Consequences of the Merger

The parties intend for the merger to be treated as a “reorganization” within the meaning of Section 368(a) of the Code for U.S. federal income tax purposes. At the time of effectiveness of the registration statement relating to this proxy statement/prospectus, Dominion Energy and SCANA have obtained written tax opinions from Morgan, Lewis & Bockius, LLP, special tax counsel to Dominion Energy, and from Mayer Brown LLP, legal counsel to SCANA, respectively, that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. In addition, Dominion Energy expects to receive an opinion from Morgan, Lewis & Bockius LLP dated the closing date of the merger, to the effect that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code and SCANA expects to receive an opinion from Mayer Brown LLP, dated the closing date of the merger, to the effect that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. These opinions were and will be based on facts and representations contained in representation letters provided by Dominion Energy and SCANA and on customary factual assumptions. The obligations of Dominion Energy and SCANA are not, however, contingent on receipt of these opinions. None of the opinions described above will be binding on the IRS or any court. Dominion Energy and

67

SCANA have not sought and will not seek any ruling from the IRS regarding any matters relating to the merger, and as a result, there can be no assurance that the IRS will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below. In addition, if any of the representations or assumptions upon which those opinions are based are inconsistent with the actual facts, the U.S. federal income tax consequences of the merger could be adversely affected. Assuming that, in accordance with the opinions described above, the merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code, upon the exchange of SCANA common stock for Dominion Energy common stock and cash in lieu of fractional shares, the U.S. federal income tax consequences will be as follows:

Upon exchanging your SCANA common stock for Dominion Energy common stock, you generally will not recognize gain or loss, except with respect to cash received in lieu of fractional shares of Dominion Energy common stock (as discussed below). The aggregate tax basis of Dominion Energy common stock that you receive in the merger (including any fractional shares deemed received) will equal your aggregate adjusted tax basis in the shares of SCANA common stock you surrender in the merger. Your holding period for the shares of Dominion Energy common stock that you receive in the merger (including any fractional share deemed received) will include your holding period for the shares of SCANA common stock that you surrender in the merger. If you acquired different blocks of SCANA common stock at different times or at different prices, Dominion Energy common stock you receive will be allocated pro rata to each block of SCANA common stock, and the basis and holding period of each block of Dominion Energy common stock you receive will be determined on a block-for-block basis depending on the basis and holding period of the blocks of SCANA common stock exchanged for such Dominion Energy common stock.

If you receive cash in lieu of a fractional share of Dominion Energy common stock, you will be treated as having received such fractional share of Dominion Energy common stock pursuant to the merger and then as having sold such fractional share of Dominion Energy common stock for cash. As a result, you generally will recognize capital gain or loss equal to the difference between the amount of cash received for such fractional share and your basis in your fractional share of Dominion Energy common stock as set forth above. Such capital gain or loss generally will be long-term capital gain or loss if, as of the effective date of the merger, your holding period for such fractional share (as described above) exceeds one year. Long-term capital gains of individuals are generally eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Accounting Treatment

Dominion Energy prepares its financial statements in accordance with GAAP. The merger will be accounted for using the acquisition method of accounting. Dominion Energy will be treated as the acquiror for accounting purposes.

No Dissenters’ Rights

In accordance with Section 33-13-102(B) of the SCBCA, SCANA shareholders will not be entitled to exercise dissenters’ rights, appraisal rights or other similar rights in connection with the merger and the other transactions contemplated by the merger agreement because the shares of SCANA common stock were listed on the NYSE as of the record date of the special meeting.

Regulatory Approvals Required for the Merger

General

Under the terms of the merger agreement, to complete the merger, Dominion Energy and SCANA must obtain approvals or consents from, or make filings with, a number of U.S. federal and state regulatory authorities. The material regulatory approvals, consents and filings include the following:

68

Dominion Energy and SCANA have made and will make various filings and submissions for the above-mentioned authorizations and approvals and will each use their reasonable best efforts to obtain these authorizations and approvals, subject to certain conditions, including that these authorizations and approvals (other than the applicable SCPSC approvals which are subject to a different standard described in the immediately following paragraph) or any law or order relating to them do not impose or require any undertakings, obligations or remedial actions that constitute a burdensome condition (which is described in the section entitled “The Merger Agreement—Reasonable Best Efforts to Obtain Regulatory Approvals” beginning on page 96 of this proxy statement/prospectus). Dominion Energy and SCANA are targeting receipt of the required authorizations, approvals and consents described in further detail below and the closing of the merger near year-end 2018. However, there can be no assurance as to the precise timing of or ultimate ability of Dominion Energy and SCANA to obtain such authorizations, approvals and consents (or any additional authorizations, approvals or consents which may otherwise become necessary) or as to the timing of or occurrence of the completion of the merger. The following is a brief summary of required federal and state regulatory filings and approvals related to the merger.

SCPSC Approval

No statute or rule expressly requires approval of the merger by the SCPSC. However, the SCPSC has in the past sought to exercise authority to review and approve business combinations similar to the merger pursuant to South Carolina Code Ann. § 58-27-1300 or, without expressly asserting jurisdiction over a merger, has issued findings that the merger was in the public interest or that there was an absence of harm to South Carolina rate payers as a result of the merger. As a result, the merger agreement contains a closing condition to the effect that the SCPSC shall have made a SCPSC merger determination. If the SCPSC fails or declines to make a SCPSC merger determination, then Dominion Energy will not be obligated to complete the merger.

In addition, on December 12, 2017, SCE&G made a public commitment to the SCPSC that on or before January 12, 2018, it would submit a comprehensive plan to reduce the costs incurred by customers associated with the abandoned NND project. On January 12, 2018, Dominion Energy and SCE&G filed the SCPSC petition with the SCPSC seeking a ruling from the SCPSC approving the merger with no material changes to the terms of the merger or making a finding that the merger is in the public interest or that there is an absence of harm to South Carolina rate payers as a result of the merger. The SCPSC petition further requests the SCPSC to approve

69

the cost recovery plan with no material change to the proposed terms, conditions or undertakings set forth in the cost recovery plan and no significant change to the economic value of the cost recovery plan, in each case as reasonably determined by Dominion Energy in good faith. There is no guarantee that the SCPSC will take these actions, or that it will not impose conditions on such approvals that result in a failure of a closing condition to the merger. It is also possible that the South Carolina General Assembly will enact legislation that will prevent the SCPSC from approving the cost recovery plan in a form that does not result in a failure of closing conditions. The SCPSC consolidated the proceedings related to the SCPSC petition with separate actions filed by the South Carolina Office of Regulatory Staff and environmental interests seeking immediate reductions to SCE&G’s rates and other relief. The SCPSC has not scheduled a date for a hearing on the consolidated proceedings but has issued a proposed schedule for comments by the parties to that proceeding which would support a hearing in November 2018.

NCUC Approval

Approval of the business combination transaction is required under N.C.G.S. § 62-111(a) for the indirect transfer of ownership of Public Service Company of North Carolina, Inc., which we refer to as PSNC, from SCANA to Dominion Energy. The standard for approval is that the merger is justified by the public convenience and necessity. In a 2016 decision, the NCUC concluded that a merger was justified by the public convenience and necessity and serves the public interest upon findings that the merger would have no adverse impact on the rates and services provide by the utility, the utility’s rate payers were protected as much as reasonably possible from potential costs and risks resulting from the merger, and the known and potential benefits of the merger were sufficient to offset the potential costs and risks. See Order Approving Merger Subject to Regulatory Conditions and Code of Conduct, Docket Nos. E-2, Sub 1095, E-7, Sub 1100, G-9, Sub 682, at 69 (Sept. 29, 2016). On January 24, 2018, Dominion Energy and SCANA filed a joint application with the NCUC seeking approval to engage in the business combination transaction. There is no guarantee that the NCUC will approve the merger or that it will not impose conditions on its approval that are unacceptable to either Dominion Energy or SCANA.

GPSC Approval

Approval of the merger is required under O.C.G.A. § 46-4-25 for the indirect transfer of ownership of SEMI, from SCANA to Dominion Energy. The GPSC must act on an application to amend a certificate of authority to reflect a change in ownership within 90 days from the date the application is deemed complete. On January 19, 2018, Dominion Energy and SEMI filed a joint application with the GPSC seeking approval of the change of ownership. The GSPC approved the change of ownership on March 20, 2018.

HSR Act and Antitrust

Completion of the merger is subject to the receipt of antitrust clearance in the United States. Under the HSR Act and the rules and regulations promulgated thereunder, the merger may not be completed until notification and report forms have been filed with the DOJ and the FTC and the applicable waiting period has expired or been terminated.

The waiting period with respect to the notification and report forms filed under the HSR Act expires 30 calendar days after the date both parties have submitted such filings, unless otherwise extended or terminated. Dominion Energy and SCANA filed the required HSR Act notification and report forms with the DOJ and FTC on January 19, 2018, and requested early termination of the HSR Act waiting period. On February 1, 2018, the FTC notified Dominion Energy and SCANA that it had granted early termination of the waiting period.

At any time before or after completion of the merger, notwithstanding the termination of the waiting period under the HSR Act, the DOJ, FTC, or any U.S. state, could take such action under the antitrust laws as each deems necessary or desirable in the public interest, including seeking to enjoin the completion of the merger or seeking divestiture of substantial assets of Dominion Energy and SCANA. Private parties also may seek to take

70

legal action under the antitrust laws under certain circumstances. There can be no assurance that the DOJ, the FTC or any other governmental entity or any private party will not attempt to challenge the merger on antitrust or competition grounds, and, if such a challenge is made, there can be no assurance as to its result. Under the merger agreement, Dominion Energy and SCANA generally must use reasonable best efforts to take all necessary actions to obtain all regulatory approvals required to complete the merger, subject to certain exceptions. If the merger is not completed within 12 months after the expiration or early termination of the applicable HSR Act waiting period, Dominion Energy and SCANA will be required to submit new notification and report forms to the DOJ and the FTC, and a new HSR Act waiting period will have to expire or be terminated before the merger can be completed.

FERC Approval

Each of Dominion Energy and SCANA is a holding company under the Public Utility Holding Company Act of 2005, which we refer to as PUHCA, that has subsidiaries that either are “public utilities,” “transmitting utilities,” “electric utilities,” “electric utility companies” or a “holding company in a holding company system that includes a transmitting utility or an electric utility company” as such terms are defined under PUHCA, the FPA and the FERC’s implementing regulations. One of the requirements of Section 203 of the FPA is that no holding company in a holding company system that includes a transmitting utility or an electric utility may purchase, acquire, merge or consolidate with a transmitting utility, an electric utility company or a holding company in a holding company system that includes a transmitting utility or electric utility company without prior FERC authorization. Consequently, the FERC’s approval of the merger under Section 203 of the FPA is required.

The FERC must authorize the merger if it finds that the merger is consistent with the public interest. The FERC has stated that, in analyzing a merger or transaction under Section 203 of the FPA, it will evaluate the impact of the merger on:

The FERC must also find that the merger will not result in the cross-subsidization by utilities of their non-utility affiliates or the improper encumbrance or pledge of utility assets. If such cross-subsidization or encumbrances were to occur as a result of the merger, the FERC then must find that such cross-subsidization or encumbrances are consistent with the public interest.

The FERC will review these factors to determine whether the merger is consistent with the public interest. If the FERC finds that the merger would adversely affect competition in wholesale electric power markets, rates for transmission or the wholesale sale of electric energy, or regulation, or that the merger would result in cross-subsidies or improper encumbrances that are not consistent with the public interest, it may, pursuant to the FPA, impose upon the merger remedial conditions intended to mitigate such effects or it may decline to authorize the merger. On February 23, 2018, Dominion Energy and SCANA filed an application with FERC seeking approval of the merger under Section 203 of the FPA. On February 26, 2018, FERC issued a notice of filing setting April 24, 2018, as the deadline for interventions and comments. Three parties filed interventions. One of the three parties commented on the application. FERC has not yet acted on the application. The FERC is required to rule on a completed merger application not later than 180 days from the date on which the completed application is filed. The FERC may, however, for good cause, issue an order extending the time for consideration of the merger application by an additional 180 days. If the FERC does not issue an order within the statutory deadline, then the transaction is deemed to be approved. Dominion Energy and SCANA expect that the FERC will approve the merger within the initial 180-day review period. However, there is no guarantee that the FERC will not extend the time period for its review or will not impose conditions on its approval that are unacceptable to Dominion Energy or SCANA.

71

NRC Approval

Completion of the merger is subject to the issuance of an order by the NRC consenting to the indirect transfer of control of NRC License No. NPF-93, Docket No. 52-027, NRC License No. NPF-94, Docket No. 52-028, and NRC License No. NPF-126, Docket No. 50-395 from SCANA to Dominion Energy as required by Section 184 of the Atomic Energy Act and the NRC’s implementing regulations in 10 C.F.R. 50.80. On January 25, 2018, Dominion Energy and SCANA filed an application requesting that NRC issue an order consenting to the indirect transfer of control of the licenses. There is no guarantee that the NRC will consent to the indirect transfer of control or that it will not impose conditions on its consent that are unacceptable to either Dominion Energy or SCANA. On March 8, 2018, NRC published a Notice regarding the proposed license transfer in the Federal Register and provided an opportunity for interested parties to request a hearing or submit written comments. The NRC’s records indicate that no timely requests for hearing or comments were submitted to the NRC, and the NRC staff’s review continues. In the meantime, the State of South Carolina and the State of Tennessee have issued their required consents to the indirect transfer of control of certain other related licenses.

FCC Approval

Under FCC regulations implementing provisions of the Communications Act of 1934, as amended, an entity holding private radio licenses for internal communications purposes generally must obtain the approval of the FCC before the direct or indirect transfer of control or assignment of those licenses. SCANA and certain SCANA subsidiaries hold FCC licenses for private internal communications and, thus, must obtain prior FCC approval to assign or transfer direct or indirect control of those licenses. Once the FCC has consented to the transfer of control, the parties have 180 days to complete the merger. If the merger does not close within 180 days of receiving FCC consent, the parties can request an extension of time to complete the transaction. The FCC customarily grants extension requests of this nature. There is no guarantee that the FCC will consent to the transfer of control or that it will not impose conditions on its consent that are unacceptable to either Dominion Energy or SCANA. While the FCC’s consent or a work-around agreement is required in connection with the transaction, if the licenses are to be maintained post-closing, the parties have not made such consents or work-around a formal condition to closing.

Three transfer of control applications were filed with the FCC on February 2, 2018. All of the applications have been consented to by the FCC. The application pertaining to PSNC was consented to on February 6, 2018. The application pertaining to SCE&G was consented to on February 21, 2018. The application pertaining to SCANA’s subsidiary SCANA Services, Inc. was consented to on March 8, 2018. In all cases, the transferor is SCANA and the transferee is Dominion Energy.

Material Contracts between SCANA and Dominion Energy

In December 2014, SCANA and Dominion Energy entered into a definitive agreement for the sale by SCANA of its subsidiary, Carolina Gas Transmission Corporation, to Dominion Energy for approximately $450 million. The sale was completed by the parties in January 2015.

Legislation Relating to the Merger

Following the announcement of the merger, the South Carolina General Assembly has considered legislation related to the merger. Three pieces of legislation are currently in conference committees having passed both Houses of the South Carolina General Assembly in different forms. The legislation is H.4375, S.954, and H.4950, the latter of which is the South Carolina 2017-2018 Budget Bill amended to include provisos related to the SCPSC petition. These bills include the following provisions, among others:

All three bills would require the SCPSC to hold a hearing on the SCPSC petition no earlier than November 1, 2018 and all three bills would require the SCPSC to issue a final order no later than December 21, 2018.

72

Both S.954 and the House version of H.4375 direct the SCPSC to impose experimental rates on SCE&G that would reduce SCE&G’s lawfully approved revenue by approximately $37 million per month (H.4375) or $26 million per month (S.954). The bills require the SCPSC to impose the experimental rates either three or five days after enactment of the legislation and the experimental rates would remain in effect pending a final order on the SCPSC petition. S.954 further requires the SCPSC to review the experimental rates 30 business days after they are imposed and allows the SCPSC to adjust the rate to the minimum degree necessary to ensure that SCE&G does not become insolvent as a result. Both S.954 and H.4375 and the provisos to H. 4950 redefine the terms “prudent” and “prudency,” require a consideration of prior acts in determining the prudency of later acts, and ascribe any lack of prudency by contractors or subcontractors to the utility. In other respects, the definitions are divergent between S.954 and H.4375 and the other bill or versions of bills.

The South Carolina General Assembly has adjourned, but will reconvene in late June 2018, and may consider a conference committee report on this legislation or other legislation. In addition, the adjournment resolution adopted by the South Carolina General Assembly allows the leadership of the House of Representatives or Senate to reconvene those bodies to consider matters related to the NND project which could include new or additional legislation.

If this legislation becomes law, it is possible that Dominion Energy would not be obligated to complete the merger if Dominion Energy reasonably determines that the legislation has or would reasonably be expected to have an adverse effect on SCANA or any of its subsidiaries. It is also possible that the SCPSC may not take action on matters that are required to satisfy Dominion Energy’s conditions to closing under the merger agreement until December 21, 2018, and Dominion Energy would not be obligated to complete the merger until such conditions are satisfied.

Litigation Relating to the Merger

Following the announcement of the merger, four lawsuits have been filed asserting claims relating to the merger. First, on January 12, 2018, a pre-existing shareholder derivative action filed purportedly on behalf of nominal defendant SCANA was amended to assert putative class action claims on behalf of SCANA shareholders in the Court of Common Pleas of the County of Richland, South Carolina: Firemen’s Retirement System of St. Louis v. Addison, et al., 2017-CP-400-7547. This lawsuit asserts claims against certain current and former officers of SCANA and members of the SCANA board for breach of fiduciary duties, waste of corporate assets, and unjust enrichment, and against Dominion Energy and Merger Sub for aiding and abetting the alleged breaches of fiduciary duties. The second and third lawsuits are two putative class actions on behalf of SCANA shareholders which have been filed in the Court of Common Pleas of the Counties of Lexington and Richland, South Carolina, respectively: City of Warren Police and Fire Retirement System v. SCANA Corporation, et al., 2018-CP-320-0268, filed January 23, 2018, and Metzler Asset Management GmbH and Joseph Heinz v. Aliff, et al., 2018-CP-400-0816, filed February 8, 2018. The second lawsuit asserts claims against an officer of SCANA and certain members of the SCANA board for breach of fiduciary duties in connection with the merger, and against SCANA, Dominion Energy and Merger Sub for aiding and abetting the alleged breaches. The third lawsuit asserts claims against certain members of the SCANA board for breach of fiduciary duties in connection with the merger, and against Dominion Energy and Merger Sub for aiding and abetting the alleged breaches. These three lawsuits were removed by Dominion Energy to the United States District Court for the District of South Carolina. The plaintiffs in the first two lawsuits have filed motions to remand those cases back to state court. Collectively, these three lawsuits allege, among other things, that the individual defendants breached their fiduciary duties by creating a false impression to investors and state regulators that the NND project was running smoothly within a reasonable budget and on schedule to increase their compensation and maintain their positions, which has exposed SCANA to billions of dollars in costs and damages in connection with numerous civil and criminal proceedings. The lawsuits also allege that the merger is designed to unlawfully divest SCANA shareholders of their holdings without providing them the maximized value to which they are entitled and without adequate information to evaluate the transaction. Specifically, these plaintiffs allege that the individual defendants were motivated to approve the merger for an inadequate price for the purpose of extinguishing the standing of SCANA shareholders to pursue the derivative claims asserted against the individual defendants in the derivative actions (as described in the section entitled “—Other Legal Proceedings” beginning on page 74 of this

73

proxy statement/prospectus) to avoid personal liability, and because they will receive significant personal financial benefits in the merger not shared by other SCANA shareholders. The lawsuits also allege that the consideration proposed in the merger fails to adequately account for and value the derivative claims asserted in the derivative actions against the individual defendants that Dominion Energy will acquire in the merger, and that, because Dominion Energy has agreed to indemnify the individual defendants in the merger agreement, it is unlikely that Dominion Energy will pursue these claims if the merger is consummated. The lawsuits also allege that the merger is unfair to SCANA shareholders because if SCANA were offered the same rate settlement terms that Dominion Energy is proposing in connection with the transaction, SCANA’s stock price would increase substantially above the value of the merger consideration. The lawsuits also allege that the merger was the result of a flawed process and self-dealing, that the merger consideration was insufficient and that certain provisions of the merger agreement might dissuade an alternative bidder from surfacing. The lawsuits seek to enjoin the merger and rescind the merger agreement. In addition, the second and third lawsuits seek in the alternative, should the merger be completed, an award of unspecified monetary damages. The fourth lawsuit is a complaint for violations of federal securities laws filed on March 15, 2018, by an alleged SCANA shareholder in the United States District Court for the District of South Carolina: Turner v. Addison, et al., 3:18-cv-728-MBS. This lawsuit asserts a claim for violation of Section 14(a) of the Exchange Act against SCANA and the SCANA board, a claim for violation of Section 20(a) of the Exchange Act against the SCANA board, and a claim for aiding and abetting against Dominion Energy and Merger Sub. The claims arise out of alleged misstatements and omissions in the Form S-4 containing a preliminary proxy statement of SCANA filed on February 14, 2018. Plaintiff seeks an order requiring defendants to disclose the alleged omitted or misrepresented information and/or an injunction to prevent consummation of the merger unless and until the alleged omitted or misrepresented information is disclosed.

Other Legal Proceedings

Certain lawsuits and regulatory actions have been filed against SCANA and SCE&G in connection with the abandonment of the NND project. If the relief requested in these matters (including a request for declaratory judgment that the BLRA is unconstitutional) is granted, Dominion Energy might not be obligated to complete the merger.

Further, several identical or substantially similar derivative actions have been filed in South Carolina state and federal court on behalf of SCANA by putative shareholders of SCANA in connection with the NND project: In re SCANA Corporation Derivative Litigation, Consol. C.A. No. 3:17-cv-03166-MBS (D.S.C.) (consolidated complaint filed January 30, 2018), Crangle v. Marsh, et al., C.A. No. 2017-CP-40-05791 (S.C. Ct. Comm. Pl., Richland Cty.) (filed September 26, 2017), Firemen’s Retirement System of St. Louis v. Addison, et al., C.A. No. 2017-CP-400-7547 (S.C. Ct. Comm. Pl., Richland Cty.) (filed December 13, 2017), subsequently removed to the United States District Court for the District of South Carolina, C.A. No. 3:18-cv-00501-MBS (D.S.C.), and Todd v. Marsh, et al., C.A. No. 2017-CP-40-006621 (S.C. Ct. Comm. Pl., Richland Cty.) (filed October 30, 2017), which we refer to collectively as the derivative actions. The plaintiffs in the derivative actions seek to assert claims derivatively on behalf of SCANA pursuant to Section 33-7-400 of the SCBCA against certain current and former SCANA directors and officers for breach of fiduciary duty, gross mismanagement, waste of corporate assets, and/or unjust enrichment arising out of the oversight, management, and abandonment of the construction of the NND project. The plaintiffs in the derivative actions allege, among other things, that SCANA’s management failed to manage the NND project, that the SCANA board failed to hold management accountable for its purported failure to manage the NND project, and that the SCANA board and SCANA’s management caused or allowed SCANA to make false and misleading statements regarding the NND project to investors. The plaintiffs in the derivative actions seek, among other things, to hold the individual defendants personally liable for the losses suffered by SCANA in connection with the abandonment of the NND project.

In the event the merger is completed, the underlying claims of SCANA asserted in the derivative actions would survive but control of the claims would transfer from SCANA to Dominion Energy. Consequently, for purposes of voting on the merger, SCANA shareholders should assume that the plaintiffs in the pending

74

derivative actions would lose their standing as SCANA shareholders to continue pursuing the derivative claims in those suits. If the derivative claims underlying the derivative actions are not resolved prior to the effective time of the merger, the Dominion Energy board may have the opportunity to determine whether it is in the best interest of Dominion Energy to pursue those claims. Additionally, Dominion Energy shareholders, including current SCANA shareholders who become Dominion Energy shareholders through the merger, may make a demand on the Dominion Energy board to pursue those claims derivatively. Whether any such demand will result in Dominion Energy pursuing such claims, or if not, whether Dominion Energy shareholders would thereafter choose to pursue such claims as so-called double derivative claims, is not known. Any recovery by Dominion Energy after the effective time of the merger may be substantially or completely offset by the obligation of Dominion Energy under the merger agreement to indemnify, and to cause SCANA to honor its obligations to indemnify, directors and officers of SCANA for liabilities relating to their service prior to the effective time. See the section entitled “—Interests of SCANA’s Directors and Executive Officers in the Merger— Director and Officer Indemnification” beginning on page 79 of this proxy statement/prospectus. Thus, if the claims are not resolved prior to the effective time of the merger, it is possible that they will not be pursued, despite the assertion by the plaintiffs in the derivative actions that such claims have substantial value to SCANA.

As has been previously disclosed in SCANA’S Form 10-K for the year ended December 31, 2017 and Form 10-Q for the quarter ended March 31, 2018, for each of SCANA and SCE&G, on January 26, 2018, the South Carolina Department of Revenue, which we refer to as the SC DOR, notified SCE&G that it was initiating an audit of SCE&G’s sales and use tax returns for the period September 1, 2008 through December 31, 2017. SCANA and SCE&G understand that the SC DOR’s position is that the exemption for sales and use tax for purchases related to the NND project should not apply because Unit 2 and Unit 3 will not be placed into service and no electricity will be manufactured for sale. On June 1, 2018, SCE&G received via email from the SC DOR a notice of proposed assessment arising from that audit of approximately $410 million plus interest, along with a transmittal / explanation of that proposed assessment. SCE&G intends to appeal the proposed assessment.

Exchange of Shares in the Merger

For a description of the exchange and payment procedures with respect to the shares of SCANA common stock under the merger agreement, please see the section entitled “The Merger Agreement—Exchange and Payment Procedures” beginning on page 90 of this proxy statement/prospectus.

Interests of SCANA’s Directors and Executive Officers in the Merger

In considering the SCANA board’s recommendation that you vote to approve the merger, you should be aware that SCANA’s directors and executive officers have economic interests in the merger that are different from, and in addition to, those of SCANA’s shareholders generally. These interests, which may create actual or potential conflicts of interests, are, to the extent material, described below. The SCANA board was aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement, in reaching its decision to approve the merger agreement, and in recommending to SCANA’s shareholders that the merger agreement be approved. For the purposes of the SCANA plans and agreements described below, the completion of the transactions contemplated by the merger agreement will constitute a change in control of SCANA.

Allegations of Class Action Suits

The directors and officers of SCANA are also alleged to have certain interests in the transaction as described in the section entitled “—Litigation Relating to the Merger” beginning on page 73 of this proxy statement/ prospectus.

Equity Compensation

Pursuant to the merger agreement, upon completion of the merger, each performance share award and restricted stock unit award will be cancelled in exchange for a cash payment, as described below. The payment

75

shall be made as soon as reasonably practicable after the effective time of the merger, but in any event within three business days thereafter; provided, however, that any performance share awards and restricted stock unit awards that are subject to Section 409A of the Code shall be paid at the earliest time permitted under, and in accordance with, the terms of the applicable award agreements and relevant documents and in accordance with Section 409A of the Code.

Treatment of Performance Share Awards

At the effective time of the merger, each performance share award that is outstanding immediately prior to the effective time of the merger will fully vest at the target level of performance and shall be cancelled and converted automatically into the right to receive the following in respect of each share of SCANA common stock underlying such performance share award: (i) the merger consideration multiplied by (ii) the average price, in cash and without interest (we refer to the product of clauses (i) and (ii) in this sentence as the equity award consideration).

Treatment of Restricted Stock Units

At the effective time of the merger, each restricted stock unit award that is outstanding immediately prior to the effective time of the merger will fully vest and be cancelled and converted automatically into the right to receive the equity award consideration in respect of each share of SCANA common stock underlying such restricted stock unit award.

Treatment of Deferred Units

At the effective time of the merger, each deferred unit in respect of SCANA common stock credited or deemed credited to the SCANA stock ledger under the SCANA Director Compensation and Deferral Plan or the SCANA Executive Deferred Compensation Plan that is outstanding immediately prior to the effective time of the merger shall be converted automatically into a number of deferred units in respect of Dominion Energy common stock equal to the product of (i) the deferred unit, multiplied by (ii) the merger consideration, to be payable pursuant to the terms of the applicable plan.

Payments under the Supplementary Key Executive Severance Benefits Plan

The SCANA Corporation Supplementary Key Executive Severance Benefits Plan, which we refer to as the Supplementary Severance Plan, provides for payments to SCANA’s senior executive officers if, within 24 months after a change in control of SCANA, a senior executive officer’s employment is terminated without “just cause” or the senior executive officer terminates his or her employment for “good reason.”

Under the Supplementary Severance Plan, SCANA would be deemed to have “just cause” for terminating the employment of a senior executive officer if he or she: (i) willfully and continually failed to substantially perform his or her duties after SCANA made demand for substantial performance; (ii) willfully engaged in conduct that is demonstrably and materially injurious to SCANA; or (iii) were convicted of a felony or certain misdemeanors.

A senior executive officer would be deemed to have “good reason” for terminating his or her employment under the Supplementary Severance Plan if, after a change in control, without his or her consent, any one or more of the following occurred: (i) a material diminution in his or her base salary; (ii) a material diminution in his or her authority, duties, or responsibilities; (iii) a material diminution in the authority, duties, or responsibilities of the supervisor to whom he or she is required to report, including a requirement that he or she report to one of our officers or employees instead of reporting directly to the SCANA board; (iv) a material diminution in the budget over which he or she retains authority; (v) a material change in the geographic location at which he or she must perform services; or (vi) any other action or inaction that constitutes a material breach by SCANA of the agreement under which he or she provides services.

76

In the event of such a termination, the Supplementary Severance Plan entitles participants to the following payments and benefits:

Pursuant to the merger agreement, with respect to Mr. Addison, Mr. Kissam and Ms. Griffin, if any such executive’s salary has not been adjusted to at least the low point of SCANA’s pre-established salary range for his or her applicable pay grade which pay grade was adjusted in respect of recent promotions, benefits under the Supplementary Severance Plan will be provided to such executive as if such executive’s salary had been adjusted to the low point. The low point of the salary range represents a salary at 85% of the midpoint of the range for an executive’s applicable pay grade. Ms. Griffin’s salary has since been adjusted to above the low point of SCANA’s pre-established salary range for her applicable pay grade.

In addition to the benefits above (unless their agreements with SCANA provide otherwise), participants in the Supplementary Severance Plan are entitled to benefit distribution under the Long-Term Equity Compensation Plan equal to 100% of the target awards for all performance periods not completed as of the date of the change in control, if any; however, the treatment of equity awards is prescribed under the merger agreement and further

77

described under the section entitled “—Interests of SCANA’s Directors and Executive Officers in the Merger—Equity Compensation” beginning on page 75 of this proxy statement/prospectus. Participants in the Supplementary Severance Plan are also be entitled to any amounts previously earned, but not yet paid, under the terms of any of SCANA’s other plans or programs.

Retirement Benefits

Supplemental Executive Retirement Plan

The SERP is an unfunded nonqualified defined benefit plan that was established for the purpose of providing supplemental retirement income to certain SCANA employees, including the executive officers. Subject to the terms of the SERP, a participant becomes eligible to receive benefits under the SERP upon termination of his or her employment with SCANA (or at such later date as may be provided in a participant’s agreement), if the participant has become vested in his or her accrued benefit under the Retirement Plan prior to termination of employment. However, if a participant is involuntarily terminated following or incident to a change in control and prior to becoming fully vested in his or her accrued benefit under the Retirement Plan, the participant will automatically become fully vested in his or her benefit under the SERP and a benefit will be payable under the SERP.

Executive Deferred Compensation Plan

The EDCP is a nonqualified deferred compensation plan in which SCANA’s executive officers, including the named executive officers, and SCANA’s directors, may participate. Amounts deferred under the EDCP are required to be paid, or begin to be paid, as soon as practicable following the earliest of a participant’s death, separation from service, or with respect to pre-2005 deferrals and hypothetical earnings thereon, disability.

Director Deferred Compensation

The Director Compensation and Deferral Plan, which we refer to as the DCDP, is a nonqualified deferred compensation plan pursuant to which SCANA’s non-employee directors may defer annual stock and cash retainer fees. Amounts are generally paid, or begin to be paid, on a separation from service from the SCANA board for any reason or a date certain previously elected by the director (and subject to the ability to make subsequent deferrals pursuant to the terms set forth in the DCDP). In addition, one director has an account balance under the Voluntary Deferral Plan, a nonqualified deferred compensation plan that was closed effective January 1, 2001, which account balance will generally be paid, or begin to be paid, upon separation from service from the SCANA board for any reason (and subject to the ability to make subsequent deferrals pursuant to the terms set forth in the Voluntary Deferral Plan).

Director Endowment Plan

The SCANA Director Endowment Plan, which was closed to new participants effective January 1, 2013, provides for SCANA to make tax deductible, charitable contributions totaling $500,000 per eligible director to institutions of higher education designated by the applicable director. A portion is contributed upon retirement of the director and the remainder upon the director’s death.

Agreements with Dominion Energy

As of the date of this proxy statement/prospectus, none of the SCANA executive officers has entered into any agreement with Dominion Energy or any of its affiliates regarding employment with, or the right to purchase or participate in the equity of, Dominion Energy or one or more of its affiliates. Prior to or following the closing of the merger, however, some or all of the SCANA executive officers may discuss or enter into agreements with Dominion Energy or any of its affiliates regarding employment with, or the right to purchase or participate in the

78

equity of, Dominion Energy or one or more of its affiliates. For information on Dominion Energy’s directors and management after the merger, please see the section entitled “—Directors and Management of Dominion Energy After the Merger” beginning on page 66 of this proxy statement/prospectus.

Director and Officer Indemnification

Under the merger agreement, after the effective time of the merger, the SCANA directors and officers are entitled to indemnification and insurance coverage relating to their service as SCANA directors and officers prior to the effective time of the merger. For a more complete description, please see the section entitled “The Merger Agreement—Indemnification and Insurance” beginning on page 108 of this proxy statement/prospectus.

Potential Payments upon a Termination in Connection with a Change in Control

In accordance with Item 402(t) of Regulation S-K under the Securities Act, the table below sets forth the estimated amounts of compensation that are based on or otherwise relate to the merger and that may be payable to those individuals who were listed in the “Summary Compensation Table” that was set out in SCANA’s most recent securities filing for which disclosure was required under Item 402(c) of Regulation S-K under the Securities Act other than executive officers who ceased to be employed by SCANA during 2017 but including Ms. Griffin, who became Chief Financial Officer of SCANA effective January 1, 2018. We refer to these individuals as the “named executive officers.” Similar information for SCANA’s other current executive officers as a group is also included in the table below.

Please see the section entitled “—Interests of SCANA’s Directors and Executive Officers in the Merger” beginning on page 75 of this proxy statement/prospectus for further information about the compensation disclosed in the table below. The amounts shown in the table below are estimates based on multiple assumptions that may or may not actually occur or be accurate on the relevant date, including the assumptions described below and in the footnotes to the table. For purposes of calculating the amounts set forth below, the salary of each of Mr. Addison and Mr. Kissam has been assumed to be adjusted to the low point of the pre-established salary range for his applicable pay grade (which pay grade was adjusted in respect of recent promotions). The amounts in the table do not otherwise reflect certain compensation actions that may occur before completion of the merger, including certain compensation actions that SCANA is permitted to take prior to the completion of the merger, as described in the section entitled “The Merger Agreement—Conduct of Business” beginning on page 105 of this proxy statement/prospectus. For purposes of calculating such amounts, the following additional assumptions were used:
