MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

Dear Shareholder:

On July 24, 2018, Summit Financial Group, Inc., or Summit, and Peoples Bankshares, Inc., or Peoples, announced a strategic business combination in which Peoples will merge with and into PB Merger Sub LLC, a wholly-owned subsidiary of Summit’s wholly-owned subsidiary, Summit Community Bank, Inc., or Summit Community Bank. The combined company, which will retain the Summit name, will have approximately $2.2 billion in assets and operate 31 full-service branches across the states of West Virginia and Virginia. Peoples is sending you this prospectus and proxy statement to invite you to attend a special meeting of Peoples shareholders to allow you to vote on the plan of merger. The special meeting will be held on November 8, 2018, at 1:30 p.m., local time, at Twin Falls State Park, located at Rte. 97, Mullens, WV, 25882.

If the merger is completed, holders of Peoples common stock may elect to receive (i) 1.7193 shares of Summit common stock, par value $2.50 per share, in exchange for each share of Peoples common stock, par value $1.00 per share, held immediately prior to the merger, which is referred to as the stock consideration, (ii) cash in the amount of $47.00 per share of Peoples common stock held immediately prior to the merger, which is referred to as the cash consideration or (iii) a combination of cash and shares of Summit common stock in accordance with the election procedures set forth in the Agreement and Plan of Merger, dated as of July 24, 2018, between Summit and Peoples, which we refer to as the merger agreement. However, the aggregate number of Peoples shares that will be converted for cash consideration will be equal to 271,020 shares, and the aggregate cash consideration will be equal to $12,737,940, or approximately 50% of the merger consideration. The remaining 50% of the merger consideration will be stock consideration consisting of an aggregate of 271,021 shares of Peoples common stock converting to a maximum of 465,967 shares of Summit common stock after applying the exchange ratio. The merger agreement provides for pro rata adjustments to and reallocation of the stock and cash elections made by Peoples shareholders in order to achieve a 50% cash and 50% stock consideration mix.

The merger consideration is subject to adjustment if Peoples’ total shareholders’ equity decreases, as specified under “The Merger Agreement—Shareholders’ Equity” beginning on page 58, and Peoples has the right to terminate the merger agreement if Summit’s stock price falls below a certain floor, as specified under “The Merger Agreement—Termination of the Merger Agreement” beginning on page 73.

The number of shares of Summit common stock that Peoples shareholders making a stock election will receive in the merger for each share of Peoples common stock is fixed. The implied value of the stock consideration that Peoples shareholders will receive in the merger will change depending on changes in the market price of Summit common stock and will not be known at the time you vote on the merger.

The market value of the stock consideration will fluctuate with the market price of Summit common stock, however the cash consideration will remain a fixed amount regardless of any change in the market value of the stock consideration. The following table presents the closing prices of Summit common stock on July 24, 2018, the last trading day before public announcement of the merger, and on September 21, 2018, the last practicable trading day before the distribution of this prospectus and proxy statement. The table also presents the implied value of the stock consideration proposed for each share of Peoples common stock converted into the stock consideration on those dates, as determined by multiplying the closing price of Summit common stock on those dates by the exchange ratio of 1.7193 provided for in the merger agreement. This table also presents the value of the cash consideration proposed for each share of Peoples common stock converted into the cash consideration, which will remain a fixed amount regardless of any change in the market value of the stock consideration.

The common stock of Summit is listed on the NASDAQ Capital Market. Summit and Peoples urge you to obtain current market quotations for Summit (trading symbol “SMMF”).

The merger and the bank merger are intended to be treated as a single integrated transaction qualifying as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and holders of Peoples common stock are not expected to recognize any gain or loss for United States federal income tax purposes on the exchange of shares of Peoples common stock for shares of Summit common stock in the merger, except to the extent of the total cash consideration and cash in lieu of any fractional shares of Summit common stock.

At the special meeting of Peoples shareholders to be held on November 8, 2018, holders of Peoples common stock will be asked to vote to (1) approve the merger agreement, which is the plan of merger, and (2) approve the adjournment of the special meeting, if necessary or appropriate, in order to further solicit proxies in favor of approval of the merger agreement. Approval of the merger agreement requires the affirmative vote of a majority of the votes cast at the Peoples special meeting at which a quorum is present.

The Peoples board of directors unanimously recommends that holders of Peoples common stock vote “FOR” approval of the merger agreement and “FOR” the approval of the adjournment of the special meeting, if necessary or appropriate, in order to further solicit proxies in favor of the merger agreement.

This prospectus and proxy statement describes the special meeting, the merger, the documents related to the merger and other related matters. Please carefully read this entire document, including “Risk Factors” beginning on page 17 for a discussion of the risks relating to the proposed merger and owning Summit common stock after the merger. You also can obtain information about Summit from documents that it has filed with the Securities and Exchange Commission.

Sincerely,

Ronald L. Bowling

President and Chief Executive Officer

Peoples Bankshares, Inc.

Neither the Securities and Exchange Commission nor any state securities commission or bank regulatory agency has approved or disapproved the Summit common stock to be issued in the merger or passed upon the adequacy or accuracy of this prospectus and proxy statement. Any representation to the contrary is a criminal offense.

The securities to be issued in the merger are not savings and deposit accounts of any bank or non-bank subsidiary of Summit or of Peoples and they are not insured by the Federal Deposit Insurance Corporation or any other governmental agency.

NOTICE OF SPECIAL MEETING OF SHAREHOLDERS

To Be Held On November 8, 2018

Notice is hereby given that a special meeting of shareholders of Peoples Bankshares, Inc, or Peoples, a West Virginia corporation, will be held at Twin Falls State Park, located at Rte. 97, Mullens, WV, 25882, on November 8, 2018, at 1:30 p.m. Eastern Time, to consider and vote upon the following matters described in the accompanying prospectus and proxy statement:

1. A proposal to approve the Agreement and Plan of Merger, dated as of July 24, 2018, by and between Summit Financial Group, Inc., or Summit, a West Virginia corporation, and Peoples, which provides for, among other things, the merger of Peoples into PB Merger Sub LLC, a wholly-owned subsidiary of Summit’s wholly-owned subsidiary, Summit Community Bank, Inc., or Summit Community Bank; and

2. A proposal to approve the adjournment of the Peoples special meeting, on one or more occasions, if necessary or appropriate, to solicit additional proxies in favor of approval of the merger agreement, or the Peoples adjournment proposal.

The merger agreement is more completely described in the accompanying prospectus and proxy statement, and a copy of the merger agreement is attached as Appendix A to the prospectus and proxy statement. Please review these materials carefully and consider fully the information set forth therein.

Only holders of record of Peoples common stock at the close of business on September 20, 2018 will be entitled to notice of, and to vote at, the Peoples special meeting and any adjournment thereof. Provided that a quorum exists for the special meeting, approval of the merger agreement requires that the number of votes cast favoring approval of the merger agreement exceeds the number of votes cast opposing approval of the merger agreement. Similarly, approval of any other proposal to be voted on at the Peoples special meeting requires the number of votes cast favoring the proposal exceeds the number of votes cast opposing the proposal.

The Peoples board of directors has carefully considered the terms of the merger agreement and believes that the merger is in the best interests of Peoples and its shareholders. The Peoples board of directors has unanimously approved the merger agreement and unanimously recommends that shareholders vote: “FOR” the approval of the merger agreement; and “FOR” the approval of the adjournment of the Peoples special meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the Peoples special meeting to approve the proposal to approve the merger agreement. In addition, directors, executive officers of Peoples and certain significant shareholders have entered into voting agreements with Summit in which the officer, director or shareholder has each agreed to vote the Peoples shares that he or she controls and beneficially owns in favor of approval of the merger agreement. See “Other Material Agreements Relating to the Merger—Voting Agreements.”

Under Section 31D-13-1302 of the West Virginia Business Corporation Act, or the WVBCA, Peoples has concluded that its shareholders will have appraisal rights in connection with the merger. To exercise appraisal rights, Peoples shareholders must strictly follow the procedures prescribed by the laws of West Virginia. These procedures are summarized under the section entitled “Proposal No. 1—Approval of the Merger Agreement—Dissenters’ or Appraisal Rights” beginning on page 30 of the accompanying prospectus and proxy statement, and Sections 31D-13-1301 through 31D-13-1331 of the WVBCA, which are attached in the accompanying prospectus and proxy statement as Appendix C.

Your vote is important. Whether or not you plan on attending the Peoples special meeting, we urge you to read the prospectus and proxy statement carefully and to please vote your shares as promptly as possible. You may vote your shares by completing and sending in the enclosed proxy card or by attending the Peoples special meeting and voting in person. You may revoke your proxy at any time before it is voted by signing and returning a properly executed proxy card with a later date with respect to the same shares, by delivering written notice that you wish to revoke your proxy to Ronald L. Bowling, at 200 First Street, Mullens, West Virginia 25882, before the Peoples special meeting or at the special meeting or by attending the Peoples special meeting and voting in person.

If you beneficially hold your shares through a bank, broker, nominee or other holder of record, you should follow the voting instructions you receive from that holder of record to vote your shares.

By Order of the Board of Directors,

Ronald L. Bowling

President and Chief Executive Officer

Mullens, West Virginia

Summit and Peoples urge you to read carefully the remainder of this prospectus and proxy statement because the information in this section may not provide all the information that might be important to you with respect to the merger or the Peoples special meeting or in determining how to vote, including the risk factors beginning on page 17.

Q: What are holders of Peoples common stock being asked to vote on?

A: Holders of Peoples common stock are being asked to vote to approve the Agreement and Plan of Merger, dated as of July 24, 2018, between Summit and Peoples, as it may be amended from time to time, referred to as the merger agreement and such proposal being referred to as the Peoples merger proposal, and to approve the adjournment of the special meeting, on one or more occasions, if necessary or appropriate, to solicit additional proxies in favor of the Peoples merger proposal, referred to as the Peoples adjournment proposal.

Q: How does the Peoples board of directors recommend I vote at the Peoples special meeting?

A: The Peoples board of directors unanimously recommends that you vote “FOR” the Peoples merger proposal and “FOR” the Peoples adjournment proposal.

Q: When and where is the special meeting of Peoples shareholders?

A: The special meeting of Peoples shareholders will be held on November 8, 2018, at 1:30 p.m., local time, at Twin Falls State Park, located at Rte. 97, Mullens, WV, 25882.

Q: What do holders of Peoples common stock need to do now?

A: After you have carefully read this prospectus and proxy statement and have decided how you wish to vote your shares, please vote your shares as soon as possible. If you are a shareholder of record, to vote by proxy card, indicate on your proxy card how you want your shares to be voted with respect to each of the matters indicated. When complete, sign, date and mail your proxy card in the enclosed postage-paid return envelope as soon as possible. If you beneficially hold your shares through a bank, broker, nominee or other holder of record, you should follow the voting instructions you receive from that holder of record to vote your shares.

Submitting your proxy by mail or directing your bank or broker to vote your shares will ensure that your shares are represented and voted at the Peoples special meeting. If you would like to attend the Peoples special meeting to vote your shares in person, see “The Peoples Special Meeting—Attending the Special Meeting” beginning on page 29.

Q: What votes are required to pass each proposal at the Peoples special meeting?

A: The approval of the merger agreement requires the affirmative vote of a majority of the votes cast at the Peoples special meeting at which a quorum is present. The approval of the Peoples adjournment proposal requires the affirmative vote of a majority of the votes cast at the Peoples special meeting. Abstentions, broker non-votes and any shares that are not voted will have no effect on the outcome of either the Peoples merger proposal or the Peoples adjournment proposal.

1

Q: What constitutes a quorum for the Peoples special meeting?

A: The presence at the Peoples special meeting, in person or by proxy, of the holders of a majority of the Peoples common stock issued and outstanding and entitled to vote will constitute a quorum for the transaction of business. If a quorum is not present, the Peoples special meeting will be postponed until the holders of the number of shares of Peoples common stock required to constitute a quorum attend. If you submit a properly executed proxy card, even if you abstain from voting, your shares of Peoples common stock will be counted for purposes of determining whether a quorum is present at the Peoples special meeting. If additional votes must be solicited to approve the merger agreement and the Peoples adjournment proposal is approved, it is expected that the Peoples special meeting will be adjourned to solicit additional proxies.

Q: Who may solicit proxies on Peoples’ behalf?

A: In addition to solicitation of proxies by Peoples by mail, proxies may also be solicited by Peoples’ directors and employees personally and by telephone, facsimile or other means. For more information on solicitation of proxies in connection with the special meeting of Peoples shareholders, see “The Peoples Special Meeting-Solicitation of Proxies” beginning on page 28.

Q: Why is my vote as a holder of Peoples common stock important?

A: If you do not vote by proxy card or vote in person at the Peoples special meeting, it will be more difficult for Peoples to obtain the necessary quorum to hold its special meeting. In addition, approval of the Peoples merger proposal requires the affirmative vote of a majority of the votes cast at the Peoples special meeting at which a quorum is present. The Peoples board of directors recommends that you vote to approve the merger agreement. Further, due to the importance of the vote to approve the merger agreement, Peoples is also seeking authority from shareholders through the Peoples adjournment proposal to adjourn the special meeting to a later date, if necessary or appropriate, in order to further solicit proxies in favor of approval of the Peoples merger proposal.

Q: If my shares are held in street name by my broker, will my broker automatically vote my shares for me?

A: No. Your broker cannot vote your shares without instructions from you. You should instruct your broker as to how to vote your shares, following the directions your broker provides to you. Please check the voting form used by your broker. Without instructions, your shares will not be voted, which will have the effect described below.

Q: What if I abstain from voting or fail to vote or instruct my broker or other holder of record how to vote?

A: If you are a record holder of Peoples common stock and you submit a proxy card in which you abstain from voting, the abstention will be counted toward a quorum at the Peoples special meeting, but it will have no effect on the outcome of the Peoples merger proposal or the Peoples adjournment proposal.

If you are a record holder of Peoples common stock and you fail to vote, it will have no effect on the outcome of the Peoples merger proposal or the Peoples adjournment proposal.

If your bank, broker, nominee or other holder of record holds your shares of Peoples common stock in “street name,” for each proposal your bank, broker, nominee or other holder of record generally will vote such shares only if you provide instructions on how to vote by filling out the voter instruction form sent to you by your broker, bank, nominee or other holder of record with this prospectus and proxy statement. Your shares held in “street name” generally will not be voted on any proposal with respect to which you do not provide voting instructions (referred to as broker non-votes). Broker non-votes will have no effect on the outcome of the Peoples merger proposal or any other proposal at the Peoples special meeting.

2

Q: Can I attend the Peoples special meeting and vote my shares in person?

A: Yes. All holders of Peoples common stock, including shareholders of record and shareholders who beneficially own their shares through banks, brokers, nominees or any other holder of record, at the close of business on September 20, 2018, which is the record date for the special meeting, are invited to attend the Peoples special meeting. Holders of record of Peoples common stock as of the record date can vote in person at the Peoples special meeting. If you wish to vote in person at the special meeting and if you are a shareholder of record, you should bring the enclosed proxy card and proof of identity. If you hold your shares in street name, through your broker or beneficially own your shares through another holder of record, you will need to bring with you proof of identity and a letter from your bank, broker, nominee or other holder of record confirming your beneficial ownership of common stock as of the record date (a “written proxy” from your holder of record). At the appropriate time during the special meeting, the shareholders present will be asked whether anyone wishes to vote in person. You should raise your hand at this time to receive a ballot to record your vote. Everyone who attends the special meeting must abide by the rules for the conduct of the meeting distributed at the meeting.

Even if you plan to attend the special meeting, you are encouraged to vote your shares as soon as possible by submitting a properly executed proxy card in the enclosed prepaid envelope.

Q: Will Peoples be required to submit the Peoples merger proposal to its shareholders even if the Peoples board of directors has withdrawn or modified its recommendation?

A: Yes. Unless the merger agreement is terminated before the Peoples special meeting, Peoples is required to submit the Peoples merger proposal to its shareholders even if the Peoples board of directors has withdrawn or modified its recommendation, consistent with the terms of the merger agreement.

Q: If I am a holder of Peoples common stock, can I change or revoke my vote?

A: Yes. If you are a shareholder of record of common stock on the record date, you may change your vote and revoke your proxy by:

If you hold shares in street name, you must follow your broker’s instructions to change your vote. Any record holder of Peoples common stock, or street name holder with a written proxy from the record holder, entitled to vote in person at the Peoples special meeting may vote in person regardless of whether a proxy has been previously given, but the mere presence of a Peoples shareholder at the special meeting will not constitute revocation of a previously given proxy.

Q: If I am a Peoples shareholder, do I have appraisal or dissenters’ rights?

A: Yes. Under West Virginia law, holders of Peoples common stock will be entitled to exercise appraisal or dissenters’ rights in connection with the Peoples merger proposal. To exercise appraisal rights, Peoples shareholders must strictly follow the procedures prescribed by the laws of West Virginia. These procedures are summarized under the section entitled “The Merger—Dissenters’ or Appraisal Rights” beginning on page 53, and Sections 31D-13-1301 through 31D-13-1331 of the West Virginia Business Corporation Act, which are attached to this prospectus and proxy statement as Appendix C.

Q: If I am a holder of Peoples common stock with shares represented by stock certificates, should I send in my Peoples stock certificates now?

A: No. You should not send in your Peoples stock certificates at this time. After completion of the merger, Summit will send you instructions for exchanging Peoples stock certificates for the merger consideration. The

3

shares of Summit common stock that Peoples shareholders will receive in the merger will be issued in book-entry form. Please do not send in your stock certificates with your proxy card.

Q: Who can I contact if I cannot locate my Peoples stock certificate(s)?

A: If you are unable to locate your original Peoples stock certificate(s), you should contact Ronald L. Bowling, President and Chief Executive Officer or Terri L. Lusk, Corporate Secretary of Peoples at 200 First Street, Mullens, West Virginia 25882, (304) 294-7115.

Q: What will I receive for my Peoples common stock?

A: In exchange for each of your shares of Peoples common stock, you may elect to receive (i) 1.7193 shares of Summit common stock for each share of Peoples common stock held immediately prior to the merger, which is referred to as the stock consideration, (ii) cash in the amount of $47.00 per share of Peoples common stock, which is referred to as the cash consideration, or (iii) a combination of cash and shares of Summit common stock in accordance with the election procedures set forth in the merger agreement. The stock consideration and the cash consideration are referred to collectively as the merger consideration.

However, the aggregate number of Peoples shares that will be converted for cash consideration will be equal to 271,020 shares, and the aggregate cash consideration will be equal to $12,737,940, or approximately 50% of the merger consideration. The remaining 50% of the merger consideration will be stock consideration consisting of an aggregate of 271,021 shares of Peoples common stock converting to a maximum of 465,967 shares of Summit common stock after applying the exchange ratio.

No guarantee can be made that you will receive the amount of the cash consideration or the stock consideration you elect. As a result of the proration procedures provided for in the merger agreement, as described in this prospectus and proxy statement, you may receive the stock consideration or the cash consideration in amounts that are different from the amounts you elect to receive.

Q: Is the merger consideration subject to adjustment?

A: Yes. The merger consideration could be subject to downward adjustment if, as of the last day of the calendar quarter immediately preceding the effective time, Peoples’ total adjusted shareholders’ equity is less than $20,100,000. In such an event, there will be a dollar-for-dollar downward adjustment to the aggregate merger consideration equal to the amount of the deficit, allocated proportionately to the cash consideration and stock consideration. If, as of the last day of the calendar quarter immediately preceding the effective time, Peoples’ total adjusted shareholders’ equity is more than $21,100,000, then Peoples will issue a special distribution in the amount of such excess to its shareholders, subject to certain limitations due to the structure of the merger and the bank merger as a reorganization under Section 368(a) of the Internal Revenue Code of 1986, as amended, which we refer to as the Code. These potential adjustments are described more fully in this prospectus and proxy statement. See “The Merger Agreement—Shareholders’ Equity” for further explanation.

In addition, there may be an adjustment to the fixed number of shares of Summit common stock that will be issued to Peoples shareholders based upon changes in the market price of Summit common stock and the NASDAQ Bank Index (IBIX) prior to the closing. However, any changes to the fixed number of shares of Summit common stock will not increase the per share value that Peoples shareholders will receive in the merger from the value calculated using the pre-announcement market price of Summit common stock. Furthermore, the Peoples board of directors may terminate the merger agreement if the average closing price of Summit common stock falls more than 15% on an actual basis and 15% on a relative basis to the NASDAQ Bank Index (IBIX) prior to the effective time, in which case the merger will not occur, unless Summit agrees to increase the number of shares of Summit common stock to be issued to holders of Peoples common stock.

4

Q: How do I elect common stock, cash or both?

A: You may indicate a preference to receive Summit common stock, cash or a combination of both in the merger by completing the stock/cash election form and letter of transmittal, referred to herein as the election form, that you will receive under separate cover. You should carefully review the instructions that will be included with the election form. The deadline to make an election is 5:00 p.m. Eastern Time on the 25th day following the mailing date of the election form.

Q: How does the consideration proration work?

A: Under the merger agreement, the number of shares of Peoples common stock to be converted into cash will equal approximately 50% of the total merger consideration. The remaining shares of Peoples common stock outstanding will be converted into a right to receive shares of Summit common stock that will equal approximately 50% of the merger consideration. In the event that Peoples shareholders elect to receive, in the aggregate, a particular form of consideration in an amount that exceeds the allocation established in the merger agreement, all shareholders who elected to receive such form of consideration will have their election prorated as contemplated in the merger agreement to the extent necessary to cause the aggregate mix of consideration to be equal to the allocation set forth in the merger agreement. Accordingly, Peoples shareholders may receive a consideration mix that is different from the consideration that they elect to receive. See “The Merger Agreement —Election Procedures; Surrender of Peoples Stock Certificates” beginning on page 58 for further explanation.

Q: Is the value of the per share consideration that I receive for my shares of Peoples common stock expected to be the same regardless of which election I make?

A: No. The value of the cash consideration will not change and is fixed at $47.00 per share. However, the value of the stock consideration will vary based on the market price of Summit common stock. There will be no adjustment to the fixed number of shares of Summit common stock that will be issued to Peoples shareholders who receive the stock consideration based upon changes in the market price of Summit common stock or Peoples common stock prior to the effective time of the merger. As result, the value of the merger consideration received by holders of Peoples common stock who receive the cash consideration may differ from the value of the merger consideration received by holders of Peoples common stock who receive the stock consideration.

The market price of Summit common stock at the time the merger is completed may vary from the price of Summit common stock on the date the merger agreement was executed, on the date of this prospectus and proxy statement, on the date of the Peoples special meeting and at the effective time of the merger as a result of various factors that are beyond the control of Summit and Peoples, including but not limited to, general market and economic conditions, changes in our respective businesses, operations and prospects, and regulatory considerations. In addition to the adoption and approval of the merger agreement by Peoples shareholders, consummation of the merger is subject to satisfaction of certain conditions that may not occur until after the Peoples special meeting. See “The Merger Agreement—Conditions to Completion of the Merger” beginning on page 61 for further explanation. Therefore, at the time of the Peoples special meeting you will not know the precise value of the stock consideration, if any, that you will receive at the effective time of the merger. You should obtain current market quotations for shares of Summit common stock.

Q: What happens if I do not make an election or my election form is not received before the election deadline?

A: Any shares of Peoples common stock with respect to which the exchange agent does not receive a properly completed election form by the election deadline, including stock certificate(s) and other transmittal materials, will be treated as no election shares. No election shares will be converted into the right to receive Summit common stock and/or cash according to the allocation procedures specified in the merger agreement. See “The Merger Agreement—Merger Consideration” beginning on page 57.

5

Q: How will I receive the merger consideration to which I am entitled?

A: After receiving the proper documentation from you and determining the proper allocations of shares of Summit common stock and cash to be paid or issued to Peoples shareholders, the exchange agent will forward to you the Summit common stock and/or cash to which you are entitled. See “The Merger Agreement—Election Procedures; Surrender of Peoples Stock Certificates” beginning on page 58. Peoples shareholders will not receive any fractional shares of Summit common stock in the merger. Instead, they will receive an amount in cash equal to the fractional share interest multiplied by $47.00, the per share cash consideration.

Q: When do you expect to complete the merger?

A: Summit and Peoples currently expect to complete the merger during the first quarter of 2019. However, they cannot assure you when or if the merger will occur. Summit and Peoples must, among other things, obtain the approval of Peoples shareholders at its special meeting and satisfy the other conditions described below in “The Merger Agreement—Conditions to Completion of the Merger” beginning on page 61.

Q: What happens if the merger is not completed?

A: If the merger is not completed, holders of Peoples common stock will not receive any consideration for their shares in connection with the merger. Instead, Peoples will remain an independent private company. In addition, in certain circumstances, a termination fee may be required to be paid by Peoples. See “The Merger Agreement—Effect of Termination; Termination Fee” beginning on page 74 for a complete discussion of the circumstances under which termination fees will be required to be paid.

Q: Who will be soliciting proxies?

A: In addition to soliciting proxies by mail, the directors and certain employees of Peoples may be soliciting proxies for the Peoples special meeting. See “The Peoples Special Meeting—Solicitation of Proxies” beginning on page 28 for more information.

Q: What are the U.S. federal income tax consequences of the merger to Peoples shareholders?

A: The merger is intended to qualify, and the obligation of Summit and Peoples to consummate the merger is conditioned upon, the receipt of an opinion from their respective legal counsel to the effect that the merger will qualify, as a “reorganization” within the meaning of Section 368(a) of the Code and that Peoples and Summit will each be treated as a party to each reorganization within the meaning of Section 368(b) of the Code. Neither Summit nor Peoples currently intends to waive this opinion condition to its obligation to consummate the merger. If either Summit or Peoples waives this opinion condition after this prospectus and proxy statement is declared effective by the SEC, and if the tax consequences of the merger to Peoples shareholders have materially changed, Summit and Peoples will recirculate appropriate soliciting materials to resolicit the votes of Peoples shareholders. Assuming that the merger and the bank merger so qualifies as a “reorganization,” which Peoples and Summit anticipate, in general, for U.S. federal income tax purposes:

For further information, see “Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 75.

The U.S. federal income tax consequences described above may not apply to all holders of Peoples common stock. Your tax consequences will depend on your individual situation. Accordingly, we strongly urge you to consult your tax advisor for a full understanding of the particular tax consequences of the merger to you.

Q: Whom should I call with questions?

A: Peoples shareholders should contact Ronald L. Bowling at Peoples by telephone at (304) 294-7115.

RISK FACTORS

In addition to general investment risks and the other information contained in or incorporated by reference into this prospectus and proxy statement, including the matters addressed under the heading “Cautionary Statement Regarding Forward-Looking Statements” on page 25 and the matters described under the caption “Risk Factors” in the Annual Report on Form 10-K filed by Summit for the year ended December 31, 2017, Peoples shareholders should consider the matters described below in determining whether to approve the merger agreement.

Because the exchange ratio is fixed, fluctuations in the trading price of Summit common stock will change the value of the shares of Summit common stock you receive in the merger.

The exchange ratio is set at 1.7193 shares of Summit common stock for each share of Peoples common stock. As a result, the market value of the Summit common stock that Peoples shareholders receive in the merger will depend on the market price of Summit common stock at the time the shares are issued. Because the exchange ratio is fixed, the value of the shares of Summit common stock that will be issued to Peoples shareholders in the merger will depend on the market price of Summit common stock at the time the shares are issued. After the merger, the market value of Summit common stock may decrease and be lower than the market value of Summit common stock that was used in calculating the exchange ratio in the merger. Except as described in this prospectus and proxy statement, there will be no adjustment to the fixed number of shares of Summit common stock that will be issued to Peoples shareholders based upon changes in the market price of Summit common stock or Peoples common stock prior to the closing.

There may be an adjustment to the fixed number of shares of Summit common stock that will be issued to Peoples shareholders based upon changes in the market price of Summit common stock and the NASDAQ Bank Index (IBIX) prior to the closing. However, any changes to the fixed number of shares of Summit common stock will not increase the per share value that Peoples shareholders will receive in the merger from the value calculated using the pre-announcement market price of Summit common stock. Furthermore, the Peoples board of directors may terminate the merger agreement if the average closing price of Summit common stock falls more than 15% on an actual basis and 15% on a relative basis to the NASDAQ Bank Index (IBIX) prior to the closing, in which case the merger will not occur, unless Summit agrees to increase the number of shares of Summit common stock to be issued to holders of Peoples common stock.

The market price of Summit common stock at the time the merger is completed may vary from the price of Summit common stock on the date the merger agreement was executed, on the date of this prospectus and proxy statement and on the date of the Peoples special meeting as a result of various factors that are beyond the control of Summit and Peoples, including, but not limited to, general market and economic conditions, changes in our respective businesses, operations and prospects, and regulatory considerations. In addition to the approval of the merger agreement by Peoples shareholders, completion of the merger is subject to satisfaction of certain conditions that may not occur until after the Peoples special meeting. See “The Merger Agreement — Conditions to Completion of the Merger” beginning on page 61 for further explanation. Therefore, at the time of the Peoples special meeting Peoples shareholders will not know the precise value of the stock consideration they will receive at the effective time of the merger. Peoples shareholders should obtain current market quotations for shares of Summit common stock.

The elections made by holders of Peoples common stock with respect to the types of merger consideration they would like to receive are subject to proration, and there can be no assurance that a shareholder will receive the type of merger consideration that he, she or it elects.

Each holder of Peoples common stock will be able to elect the type of merger consideration that he, she or it would like to receive for each of his, her or its shares of Peoples common stock, including electing to receive the cash consideration for a portion of his, her or its shares of Peoples common stock and receive the stock

17

consideration for the remainder of his, her or its shares of Peoples common stock. We refer to a share of Peoples common stock for which an election to receive the cash consideration is made as a cash election share and a share of Peoples common stock for which an election to receive the stock consideration is made as a stock election share. Shares of Peoples common stock for which no election is made will be deemed to be no-election shares. All such elections are subject to adjustment on a pro rata basis.

The merger agreement provides that the aggregate number of Peoples shares that will be converted for cash consideration will be equal to 271,020 shares, and the aggregate cash consideration will be equal to $12,737,940, or approximately 50% of the merger consideration. The remaining 50% of the merger consideration will be stock consideration consisting of an aggregate of 271,021 shares of Peoples common stock converting to a maximum of 465,967 shares of Summit common stock after applying the exchange ratio. As a result, all elections may be subject to proration depending on the elections made by other holders of Peoples common stock if the cash consideration (or the stock consideration) is undersubscribed or oversubscribed. Proration will be applied so that ultimately approximately 50% of the shares of Peoples common stock are treated as cash election shares and approximately 50% of the shares of Peoples common stock are treated as stock election shares.

For example, if the aggregate of the cash consideration payable to holders of cash election shares is in excess of the maximum cash consideration, all of the no-election shares will be treated as stock election shares and a number of cash election shares will be converted into stock election shares until the maximum cash consideration is no longer oversubscribed. If the aggregate of the cash consideration payable to holders of cash election shares is less than the maximum cash consideration, a number of no-election shares will be treated as cash election shares until the maximum cash consideration is no longer undersubscribed and, if necessary or appropriate, a number of stock election shares will be converted into cash election shares until the maximum cash consideration is no longer undersubscribed.

Accordingly, depending on the elections made by other Peoples shareholders, if a holder of Peoples common stock elects to receive all cash consideration pursuant to the merger, such holder may receive a portion of the merger consideration due to such holder in the form of stock consideration. If a holder of Peoples common stock elects to receive all stock consideration pursuant to the merger, such holder may receive a portion of the merger consideration due to such holder in the form of cash consideration. Holders of Peoples common stock who make an election to receive the stock consideration for some of their shares and the cash consideration for the remainder of their shares may receive different amounts or proportions of the stock consideration and the cash consideration than they elected.

The market price of Summit common stock after the merger may be affected by factors different from those affecting the shares of Peoples or Summit currently.

Upon completion of the merger, holders of Peoples common stock will become holders of Summit common stock. Summit’s business differs from that of Peoples, and, accordingly, the results of operations of the combined company and the market price of the combined company’s shares of common stock may be affected by factors different from those currently affecting the independent results of operations of each of Summit and Peoples. For a discussion of the businesses of Summit and Peoples and of certain factors to consider in connection with those businesses, see the documents incorporated by reference or described elsewhere in this prospectus and proxy statement.

The integration of the operations of Summit and Peoples may be more difficult, costly or time-consuming than anticipated.

The success of the merger will depend, in part, on Summit’s ability to realize the anticipated benefits and cost savings from successfully combining the businesses of Summit and Peoples and to combine the businesses of Summit and Peoples in a manner that permits growth opportunities and cost savings to be realized without materially disrupting the existing customer relationships of Peoples or decreasing revenues due to loss of customers. If Summit is not able to achieve these objectives, the anticipated benefits and cost savings of the merger may not be realized fully or at all or may take longer to realize than expected.

18

It is possible that the integration process could result in the loss of key employees, the disruption of each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the combined company’s ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits of the merger. The loss of key employees could adversely affect Summit’s ability to successfully conduct its business in the markets in which Peoples now operates, which could have an adverse effect on Summit’s financial results and the value of its common stock. If Summit experiences difficulties with the integration process, the anticipated benefits of the merger may not be realized fully or at all, or may take longer to realize than expected. As with any merger of financial institutions, there also may be business disruptions that cause Peoples to lose customers or cause customers to remove their accounts from Peoples and move their business to competing financial institutions. Integration efforts between the two companies will also divert management attention and resources. These integration matters could have an adverse effect on each of Peoples and Summit during this transition period and for an undetermined period after consummation of the merger.

The success of the merger will also depend on Summit’s ability to:

Summit may not be able to manage effectively its growth resulting from the merger.

Summit may fail to realize the cost savings estimated for the merger.

Although Summit estimates that it will realize cost savings of approximately $960,000 (pre-tax) annually (excluding one-time costs and expenses associated with the merger with Peoples) from the merger when fully phased in, it is possible that the estimates of the potential cost savings could turn out to be incorrect. For example, the combined purchasing power may not be as strong as expected, and therefore the cost savings could be reduced. In addition, future business developments may require Summit to continue to operate or maintain some facilities or support functions that are currently expected to be combined or reduced. The cost savings estimates also depend on Summit’s ability to combine the businesses of Summit and Peoples in a manner that permits those costs savings to be realized. If the estimates turn out to be incorrect or Summit is not able to combine the two companies successfully, the anticipated cost savings may not be fully realized or realized at all, or may take longer to realize than expected.

The merger with Peoples may distract management of Summit from its other responsibilities.

The acquisition of Peoples could cause the management of Summit to focus its time and energies on matters related to the acquisition that otherwise would be directed to the business and operations of Summit. Any such distraction on the part of management, if significant, could affect its ability to service existing business and develop new business and adversely affect the business and earnings of Summit.

If the merger is not completed, Summit and Peoples will have incurred substantial expenses without realizing the expected benefits of the merger.

Each of Summit and Peoples has incurred and will continue to incur substantial expenses in connection with the negotiation and completion of the transactions contemplated by the merger agreement, as well as the costs

19

and expenses of filing, printing and mailing this prospectus and proxy statement and all filing and other fees paid to the SEC in connection with the merger. If the merger is not completed, Summit and Peoples would have to recognize these expenses without realizing the expected benefits of the merger.

Peoples shareholders will have less influence as shareholders of Summit than as shareholders of Peoples.

Peoples shareholders currently have the right to vote in the election of the board of directors of Peoples and on other matters affecting Peoples. Following the merger, the shareholders of Peoples as a group will own approximately 3.6% of the combined organization. When the merger occurs, each Peoples shareholder that receives shares of Summit common stock will become a shareholder of Summit with a percentage ownership of the combined organization much smaller than such shareholder’s percentage ownership of Peoples. Because of this, Peoples shareholders will have less influence on the management and policies of Summit than they now have on the management and policies of Peoples.

Some of the directors and executive officers of Peoples may have interests in the merger that differ from the interests of non-director or non-management shareholders.

The interests of some of the directors and executive officers of Peoples may be different from those of holders of Peoples common stock, and directors and executive officers of Peoples may be participants in arrangements that are different from, or in addition to, those of holders of Peoples common stock. These interests are described in more detail in the section entitled “The Merger—Interests of Certain Peoples Directors and Executive Officers in the Merger” beginning on page 55.

The fairness opinion delivered to the Peoples board of directors by Peoples’ financial advisor prior to the signing of the merger agreement will not reflect changes in circumstances occurring after the date of such opinion.

The opinion of Ambassador, Peoples’ financial advisor, to the Peoples board of directors, was delivered on, and was dated, July 24, 2018. Changes in the operations and prospects of Peoples or Summit, general market and economic conditions and other factors that may be beyond the control of Peoples and Summit may alter the value of Peoples or Summit or the prices of shares of Peoples common stock or Summit common stock by the time the merger is completed. The opinion does not speak as of the time the merger will be completed or as of any date other than the date of such opinion. The opinion is included as Appendix B to this prospectus and proxy statement. For a description of the opinion, please refer to “The Merger—Opinion of Peoples’ Financial Advisor” on page 39. For a description of the other factors considered by Peoples’ board of directors in determining to approve the merger, please refer to “The Merger—Peoples’ Reasons for the Merger; Recommendation of the Peoples Board of Directors” on page 34.

The merger agreement limits Peoples’ ability to pursue an alternative acquisition proposal and requires Peoples to pay a termination fee of $1,275,000 under limited circumstances relating to alternative acquisition proposals.

The merger agreement prohibits Peoples from soliciting, initiating, or encouraging certain alternative acquisition proposals with any third party, subject to exceptions set forth in the merger agreement. See “The Merger Agreement—Acquisition Proposals” on page 65. The merger agreement also provides for the payment by Peoples of a termination fee in the amount of $1,275,000 in the event that the other party terminates the merger agreement for certain reasons. These provisions might discourage a potential competing acquiror that might have an interest in acquiring all or a significant part of Peoples from considering or proposing such an acquisition. See “Merger Agreement—Termination Fee” on page 74.

20

The merger will not be completed unless important conditions are satisfied.

Specified conditions set forth in the merger agreement must be satisfied or waived to complete the merger. If the conditions are not satisfied or waived, to the extent permitted by law or stock exchange rules, the merger will not occur or will be delayed and each of Summit and Peoples may lose some or all of the intended benefits of the merger. The following conditions, in addition to other closing conditions, must be satisfied or waived, if permissible, before Summit and Peoples are obligated to complete the merger:

Some of the conditions to the merger may be waived by Summit or Peoples without resoliciting shareholder approval of the merger agreement.

Some of the conditions set forth in the merger agreement may be waived by Summit or Peoples, subject to the agreement of the other party in specific cases. See “The Merger Agreement—Conditions to Completion of the Merger” on page 61. If any conditions are waived, Peoples will evaluate whether an amendment of this prospectus and proxy statement and resolicitation of proxies is warranted. In the event that the board of directors of Peoples determines that resolicitation of shareholders is not warranted, Summit and Peoples will have the discretion to complete the transaction without seeking further Peoples shareholder approval.

Termination of the merger agreement could negatively impact Peoples.

If the merger agreement is terminated, there may be various consequences. For example, Peoples’ businesses may have been impacted adversely by the failure to pursue other beneficial opportunities due to the focus of management on the merger, without realizing any of the anticipated benefits of completing the merger. If the merger agreement is terminated and the Peoples board of directors seeks another merger or business combination, Peoples shareholders cannot be certain that Peoples will be able to find a party willing to pay the equivalent or greater consideration than that which Summit has agreed to pay in the merger. In addition, if the merger agreement is terminated under certain circumstances, including circumstances involving a change in recommendation by Peoples’ board of directors, Peoples may be required to pay Summit a termination fee of $1,275,000, which could have an adverse effect on Peoples’ financial condition.

Failure to complete the merger could negatively affect the market price of Peoples common stock.

If the merger is not completed for any reason, Peoples will be subject to a number of material risks, including the following:

21

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

Upon completion of the merger, Peoples shareholders who receive Summit common stock will become Summit shareholders and their rights as shareholders will be governed by Summit’s articles of incorporation and Summit’s bylaws. The rights associated with Peoples common stock are different from the rights associated with Summit common stock. Please see “Comparative Rights of Shareholders” beginning on page 85 for a discussion of the different rights associated with Summit common stock.

Peoples will be subject to business uncertainties and contractual restrictions while the merger is pending.

Uncertainty about the effect of the merger on employees and customers may have an adverse effect on Peoples. These uncertainties may impair Peoples’ ability to attract, retain and motivate strategic personnel until the merger is consummated, and could cause customers and others that deal with Peoples to seek to change existing business relationships with Peoples. Experienced employees in the financial services industry are in high demand, and competition for their talents can be intense. Employees of Peoples may experience uncertainty about their future role with the surviving corporation until, or even after, strategies with regard to the combined company are announced or executed. If strategic Peoples employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the surviving corporation, Peoples’ business following the merger could be harmed. In addition, the merger agreement restricts Peoples from making certain acquisitions and taking other specified actions until the merger occurs without the consent of Summit. These restrictions may prevent Peoples from pursuing attractive business opportunities that may arise prior to the completion of the merger. See “The Merger Agreement—Conduct of Business Pending the Merger” on page 68.

If the merger and the bank merger do not constitute a reorganization under Section 368(a) of the Code, then each Peoples shareholder may be responsible for payment of U.S. income taxes related to the merger.

The United States Internal Revenue Service, or the IRS, may determine that the merger and the bank merger do not qualify as a nontaxable reorganization under Section 368(a) of the Code. In that case, each Peoples shareholder would recognize a gain or loss equal to the difference between the (i) the sum of the fair market value of Summit common stock and the amount of cash consideration, if any, received by the Peoples shareholder in the merger and (ii) the Peoples shareholder’s adjusted tax basis in the shares of Peoples common stock exchanged therefor.

SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA OF SUMMIT

The following table summarizes selected historical consolidated financial data of Summit for the periods and as of the dates indicated. This information has been derived from Summit’s consolidated financial statements filed with the SEC. Historical financial data as of and for the six months ended June 30, 2018 and June 30, 2017 are unaudited and include, in management’s opinion, all normal recurring adjustments considered necessary to present fairly the results of operations and financial condition of Summit. You should not assume the results of operations for past periods and for the six months ended June 30, 2018 and June 30, 2017 indicate results for any future period.

You should read this information in conjunction with Summit’s consolidated financial statements and related notes thereto included in Summit’s Annual Report on Form 10-K as of and for the year ended December 31, 2017, and in Summit’s Quarterly Report on Form 10-Q as of and for the six months ended June 30, 2018, which are incorporated by reference into this prospectus and proxy statement. See “Where You Can Find More Information” beginning on page 91 of this prospectus and proxy statement.

Summit—Historical Financial Information

23

PRICE RANGE OF COMMON STOCK AND DIVIDENDS

Summit common stock is traded on NASDAQ under the symbol “SMMF.” There is no established public trading market for Peoples common stock. The closing sale price reported for Summit common stock on July 24, 2018, the last trading date preceding the public announcement of the merger agreement, was $26.79. On September 21, 2018, the last practicable trading date before the distribution of this prospectus and proxy statement, the closing sales price per share of Summit common stock was $24.24.

The following table sets forth for the periods indicated the high and low prices per share of Summit common stock as reported on NASDAQ. The per share prices do not include adjustments for markups, markdowns or commissions.

As of September 21, 2018, the last date prior to distribution of this prospectus and proxy statement for which it was practicable to obtain this information, there were approximately 1,154 registered holders of Summit common stock and approximately 129 registered holders of Peoples common stock.

The following table sets forth historical per share market values for Summit common stock (i) on July 24, 2018, the last trading day prior to public announcement of the merger agreement, and (ii) on September 21, 2018, the most recent practicable date before the printing and mailing of this prospectus and proxy statement. The table also shows the equivalent pro forma market value of Peoples common stock on those dates. Peoples common stock is not listed on any stock exchange or quoted on any interdealer quotation system.

The equivalent pro forma market value of Peoples common stock is obtained by multiplying the historical market price of Summit common stock by the applicable exchange ratio. For purposes of determining the equivalent pro forma market value and the applicable exchange ratio, we have assumed that the average closing price of a share of Summit common stock is equal to the historical market price on July 24, 2018 and September 21, 2018. Accordingly, the pro forma market value (i) on July 24, 2018 is determined by multiplying $26.79 by the exchange ratio and (ii) on September 21, 2018 is determined by multiplying $24.24 by the exchange ratio.

The historical market prices represent the last sale prices on or before the dates indicated. The average closing price of Summit common stock used to determine the exchange ratio and the market price may be higher or lower than the closing prices of Summit common stock on the dates shown in the table and, therefore, the

24

market value of the Summit common stock that you receive may be higher or lower than the equivalent pro forma market value shown in the table.

Historical Market Price

The market price of Summit common stock will fluctuate between the date of this prospectus and proxy statement and the effective time of the merger. Peoples shareholders should obtain current stock price quotations for Summit common stock. No assurance can be given concerning the market price of Summit common stock before or after the effective time of the merger. Any change in the market price of Summit common stock prior to the effective time of the merger will affect the market value of the merger consideration that Peoples’ shareholders will receive upon the effective time of the merger. Once the merger is completed, there will be no further private or public market for Peoples common stock.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and proxy statement contains or incorporates by reference a number of “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, including statements about the financial conditions, results of operations, earnings outlook and prospects of Summit, Peoples and the potential combined company and may include statements for the period following the completion of the merger. You can find many of these statements by looking for words such as “plan,” “believe,” “expect,” “intend,” “anticipate,” “estimate,” “project,” “potential,” “possible” or other similar expressions which identify these forward-looking statements and appear in a number of places in this prospectus and proxy statement (and the documents to which you are referred in this prospectus and proxy statement) and include, but are not limited to, all statements relating directly or indirectly to the timing or likelihood of completing the merger to which this prospectus and proxy statement relates, the timing and amount of growth and cost savings realized, following the merger, plans for future growth and other business development activities as well as capital expenditures, financing sources and the effects of regulation and competition, potential effects of not approving proposals discussed in this prospectus and proxy statement or not completing the merger, and all other statements regarding the intent, plans, beliefs or expectations of Summit, Peoples, or those of their respective directors or officers.

The forward-looking statements involve certain risks and uncertainties. The ability of either Summit or Peoples to predict results or the actual effects of its plans and strategies, or those of the combined company, is subject to inherent uncertainty. Factors that may cause actual results or earnings to differ materially from such forward-looking statements include those set forth on page 17 under “Risk Factors,” as well as, among others, the following:

25

Because these forward-looking statements are subject to assumptions and uncertainties, actual results may differ materially from those expressed or implied by these forward-looking statements. You are cautioned not to place undue reliance on these statements, which speak only as of the date of this prospectus and proxy statement or the date of any document incorporated by reference in this prospectus and proxy statement.

All subsequent written and oral forward-looking statements concerning the merger or other matters addressed in this prospectus and proxy statement and attributable to Summit or Peoples or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this prospectus and proxy statement. Except to the extent required by applicable law or regulation, Summit and Peoples undertake no obligation to update these forward-looking statements to reflect events or circumstances after the date of this prospectus and proxy statement or to reflect the occurrence of unanticipated events.

26

THE PEOPLES SPECIAL MEETING

This section contains information about the special meeting of Peoples shareholders that has been called to consider and approve the merger agreement.

Together with this prospectus and proxy statement, Peoples is also sending you a notice of the special meeting and a proxy card that is solicited by the Peoples board of directors. The special meeting will be held on November 8, 2018, at 1:30 p.m., local time, at Twin Falls State Park, located at Rte. 97, Mullens, WV, 25882.

Matters to Be Considered

At the Peoples special meeting, you will be asked to consider and vote upon the following matters:

Other Business

We do not expect that any matter other than the Peoples merger proposal and the Peoples adjournment proposal will be brought before the Peoples special meeting. If, however, any other matter shall be properly brought before the Peoples special meeting, the shares represented by a valid proxy will be voted by the named proxies, to the extent entitled, in accordance with their best judgment.

Proxies

Each copy of this prospectus and proxy statement mailed to record holders of Peoples common stock is accompanied by a proxy card with instructions for voting. The Peoples board of directors requests that you submit your proxy promptly, whether or not you plan to attend the meeting. If you hold your shares of Peoples common stock under your own name (also known as “record ownership”), you can vote your shares in one of the following manners:

Any vote by proxy card may be revoked by you at any time before the meeting by giving written notice of such revocation to the corporate secretary or executing another proxy as of a date subsequent to the prior proxy card. If you are a shareholder of record or have a legal proxy from a shareholder of record, you may also revoke your proxy by voting in person at the special meeting.

If you hold your shares in “street name” through a bank, broker, nominee or other holder of record, you will receive a voting instruction form directly from them. Follow the instructions on the form they provide to have your shares voted by proxy. If you wish to attend the meeting and vote in person, you must obtain a written proxy, executed in your favor, from the bank, broker, nominee or other holder of record to do so.

All shares represented by valid proxies that Peoples receives through this solicitation and that are not revoked will be voted in accordance with your instructions on the proxy card, or with respect to shares beneficially held in “street name,” in accordance with the voting instructions received from the appropriate bank,

27

broker, nominee or other holder of record. If you make no specification on your proxy card as to how you want your shares voted before signing and returning it, your proxy will be voted “FOR” each of the proposals described above.

Peoples shareholders with shares represented by stock certificates should not send Peoples stock certificates with their proxy cards. Prior to the effective time, holders of Peoples common stock with shares represented by stock certificates or held in book-entry form will be mailed an election form with instructions on how to exchange their Peoples stock certificates or book-entry shares for the merger consideration.

Solicitation of Proxies

Peoples will bear the entire cost of soliciting proxies from its shareholders. In addition to solicitation of proxies by mail, proxies may also be solicited by Peoples’ directors and employees personally and by telephone, facsimile, or other means. No additional compensation will be paid to these individuals for proxy solicitation nor is it expected to result in more than a minimal cost. Peoples may make arrangements directly with banks, brokerage houses, custodians, nominees and fiduciaries to forward solicitation material to the beneficial owners of Peoples common stock held of record by them and to obtain authorization for the execution of proxies. Peoples expects to reimburse these institutional holders for their reasonable expenses in connection with these activities.

Record Date

The close of business on September 20, 2018 has been fixed as the record date for determining the Peoples shareholders entitled to receive notice of and to vote at the special meeting. At that time, 542,041 shares of Peoples common stock were outstanding and entitled to vote at the special meeting, held by approximately 129 holders of record.

Quorum and Voting Rights

The presence, in person or by proxy, of the holders of a majority of the outstanding shares of Peoples common stock entitled to vote is necessary to constitute a quorum at the special meeting. Abstentions and broker non-votes will be counted for the purpose of determining whether a quorum is present. If a quorum exists, the approval of the Peoples merger proposal and the Peoples adjournment proposal requires the affirmative vote of a majority of the votes cast at the Peoples special meeting.

As of the record date, Peoples directors, executive officers and certain significant shareholders had the right to vote 152,836 shares of Peoples common stock, or approximately 28.20% of the outstanding Peoples common stock entitled to be voted at the special meeting. Each of these individuals has agreed to vote their shares of Peoples common stock in favor of the proposals to be presented at the special meeting in accordance with a voting agreement executed by each such individual.

At this time, the Peoples board of directors anticipates that the 150,000 shares of Peoples common stock held by the co-trustees of the Trust under the Will of H. E. Lilly, which represents 27.67% of the outstanding shares of Peoples common stock as of the record date, will be present at the special meeting for the purposes of establishing a quorum. However, the Peoples board of directors expect that the co-trustees will abstain from voting on the Peoples merger proposal or the Peoples adjournment proposal due to a potential limitation contained in the trust’s governing document relating to the co-trustees’ power to vote shares on the matters brought before the meeting.

If you are a holder of Peoples common stock and you submit a proxy in which you abstain from voting, the abstention will be counted toward a quorum at the Peoples special meeting, but it will have no effect on the outcome of either the Peoples merger proposal or the Peoples adjournment proposal.

28

Brokers, banks, nominees and other holders of record holding shares of Peoples common stock in “street name” may only vote your shares of Peoples common stock on the Peoples merger proposal and the Peoples adjournment proposal if you provide instructions on how to vote. If you do not provide instructions on how to vote by filling out the voter instruction form sent to you by your broker, bank, nominee or other holder of record, your shares will not be voted on any proposal with respect to which you did not provide instructions. Broker non-votes will have no effect on the Peoples merger proposal, and will have no effect on the Peoples adjournment proposal.

Voting Agreement Executed by Directors, Executive Officers and Certain Shareholders of Peoples

Concurrently with execution of the merger agreement, each of the directors of Peoples, in their capacities as shareholders of Peoples, executive officers and certain significant shareholders entered into a voting agreement, a form of which is included as an exhibit to Appendix A attached to this prospectus and proxy statement, with Summit, under which such individuals agreed to vote their shares of Peoples common stock in favor of the merger agreement and the merger at the Peoples special meeting.

Attending the Special Meeting

All holders of Peoples common stock, including holders of record and shareholders who beneficially hold their stock through banks, brokers, nominees or any other holder of record, are invited to attend the special meeting. Shareholders of record on the record date can vote in person at the special meeting. If you beneficially hold your shares in “street name,” you must obtain a written proxy executed in your favor from the record holder of your shares, such as a broker, bank or other nominee, to be able to vote in person at the special meeting. If you plan to attend the special meeting, you must either hold your shares in your own name or have a letter from the record holder of your shares confirming your ownership.

29

PROPOSALS TO BE CONSIDERED AT THE PEOPLES SPECIAL MEETING

PROPOSAL NO. 1

APPROVE THE MERGER AGREEMENT

Peoples is asking its shareholders to approve the merger agreement. For a detailed discussion of the merger, including the terms and conditions of the merger agreement, see “The Merger Agreement” beginning on page 57. As discussed in detail in the sections entitled “The Merger—Peoples’ Reasons for the Merger; Recommendation of the Peoples Board of Directors” beginning on page 34, after careful consideration, the Peoples board of directors determined that the terms of the merger agreement and the transactions contemplated thereby are in the best interests of Peoples and the board unanimously approved the merger agreement. Accordingly, Peoples’ board of directors unanimously recommends that Peoples shareholders vote “FOR” the Peoples merger proposal.

Required Vote

Approval of the Peoples merger proposal requires the affirmative vote of a majority of the votes cast at the Peoples special meeting at which a quorum is present. You are entitled to one vote for each share of Peoples common stock you held as of the record date.

The affirmative vote of the holders of a majority of the votes cast on the matter, assuming a quorum is present at the special meeting, is needed in order to proceed with the merger. An abstention will have no effect on the outcome of either the Peoples merger proposal or the Peoples adjournment proposal. The Peoples board of directors urges Peoples shareholders to promptly vote by completing, dating and signing the accompanying proxy card and returning it promptly in the enclosed postage-paid envelope, or, if you hold your stock in “street name” through a bank, broker, nominee or other holder of record, by following the voting instructions of your bank, broker, nominee or other holder of record. If you hold stock in your name as a shareholder of record, you may complete, sign, date and mail your proxy card in the enclosed postage paid return envelope or vote in person at the Peoples special meeting. If you hold your stock in “street name” through a bank, broker, nominee or other holder of record, you must direct your bank or broker to vote in accordance with the instruction form forwarded to you by your bank or broker. This voting instruction form provides instructions on voting by mail.

Recommendation of the Peoples Board of Directors

The Peoples board of directors recommends that you vote “FOR” approval of the Peoples merger proposal. See “The Merger—Peoples’ Reasons for the Merger; Recommendation of the Peoples Board of Directors” on page 34 for a more detailed discussion of the Peoples board of directors’ recommendation.

PROPOSAL NO. 2

APPROVE GRANTING THE BOARD OF DIRECTORS AUTHORITY TO ADJOURN THE PEOPLES

SPECIAL MEETING, IF NECESSARY OR APPROPRIATE, TO PERMIT FURTHER SOLICITATION OF PROXIES

If at the Peoples special meeting the number of shares of common stock present in person or represented by proxy and voting in favor of the Peoples merger proposal is insufficient to approve such proposal, management may move to adjourn the special meeting on one or more occasions in order to enable the board of directors to continue to solicit additional proxies in favor of such proposal; however, the special meeting may not be adjourned, postponed or continued to a date later than January 18, 2019. In that event, you will be asked to vote only upon the Peoples adjournment proposal and will not be asked to vote on the Peoples merger proposal at the special meeting.

In this proposal, Peoples is asking the Peoples shareholders to authorize the holder of any proxy solicited by its board of directors to grant to the Peoples board of directors the authority to adjourn the special meeting and any later adjournments. If the Peoples shareholders approve this proposal, Peoples could adjourn the special meeting, and any adjourned session of the special meeting on one or more occasions, to use the additional time to solicit proxies in favor of the Peoples merger proposal, including the solicitation of proxies from the shareholders that have previously voted against such proposal. Among other effects, approval of this proposal could mean that, even if proxies representing a sufficient number of votes against the approval of the Peoples merger proposal have been received, Peoples could adjourn the special meeting without a further shareholder vote on such proposal and seek to convince the holders of those shares to change their votes to vote in favor of such proposal.

Generally, if the special meeting is adjourned, no notice of the adjourned meeting is required to be given to shareholders, other than an announcement at the Peoples special meeting of the place, date and time to which the meeting is adjourned.

Required Vote

Approval of the Peoples adjournment proposal requires the affirmative vote of a majority of the votes cast at the Peoples special meeting. An abstention will have the no effect on the outcome of either the Peoples merger proposal or the Peoples adjournment proposal.

Recommendation of the Peoples Board of Directors

The Peoples board of directors believes that if the number of shares of its common shares present in person or represented by proxy at the Peoples special meeting and voting in favor of the approval of the merger agreement is insufficient to approve such proposal, it is in the best interests of the Peoples shareholders to enable the board of directors, for a limited period of time, to continue to seek to obtain a sufficient number of additional votes to approve such proposal. The Peoples board of directors unanimously recommends that shareholders vote “FOR” the approval of the Peoples adjournment proposal.

THE MERGER

The following summary describes certain aspects of the merger, including all the terms of the merger agreement that the respective managements of Peoples and Summit believe are material. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. The merger agreement is attached to this prospectus and proxy statement as Appendix A and is incorporated by reference in this prospectus and proxy statement. You are urged to read the merger agreement carefully and in its entirety, as it is the legal document governing the merger.

Background and Negotiation of the Merger

The board of directors and executive management of Peoples have regularly reviewed and assessed various business strategies and objectives and considered various business strategies and options to enhance shareholder value and the liquidity of Peoples capital stock.

On January 11, 2016, the Peoples board of directors considered the request of a family group of shareholders to redeem their stock. The board of directors ultimately deferred the decision on whether to redeem the family’s shares and instead authorized the engagement of an investment banking firm to provide advice on the valuation of Peoples shares and to assist in strategic planning to improve earnings and shareholder liquidity, including strategic alliances with other financial institutions, expansion by branching, relocation of Peoples to another area, potential mergers and acquisitions, and the sale of Peoples.

An investment banking firm was hired in January 2016, and during that month, Peoples’ president and chief executive officer, Ronald L. Bowling, met with that firm to discuss the value and liquidity of Peoples’ stock, as well as Peoples’ options, including the options outlined above. The investment banking firm agreed to consider and explore these options. Mr. Bowling reported the results of this meeting to Peoples’ board of directors on February 8, 2016. The board took Mr. Bowling’s report under advisement.

On March 30, 2016, Mr. Bowling and Peoples’ legal counsel, Jackson Kelly PLLC, met with that investment banking firm to discuss strategic options and methods to increase shareholder value and liquidity. On May 16, 2016, the board of directors of Peoples met with the investment banking firm and Jackson Kelly at the offices of Jackson Kelly. The investment banking firm provided data about the value of Peoples stock and presented a number of alternatives for consideration. These alternatives included reincorporation in another jurisdiction, expansion of the market through the opening or acquisition of additional branches, a merger with a similarly-sized and situated financial institution and a sale to a third party. On May 17, 2016, the board of directors determined not to repurchase Peoples’ shares from the family group that requested the repurchase. Rather, the board decided that Peoples would continue to work with the investment banking firm and independently attempt to increase the liquidity and overall value of its stock.

During the period between May 2016 and August 2017, independently from any investment banking firm, Peoples engaged in separate discussions with two other similarly-situated institutions with respect to a merger of equals. Ultimately, these discussions were mutually terminated by the parties, because the parties were unable to reconcile their operations, markets and employee compensation issues.

In September 2017, Peoples contacted Ambassador Financial Group, Inc. regarding its potential engagement to act as Peoples’ financial advisor in connection with a possible sale of Peoples. Based on preliminary feedback from Ambassador regarding valuation and Ambassador’s description of its services, Peoples’ board of directors authorized Mr. Bowling to negotiate the engagement of Ambassador. On December 11, 2017, the board of directors met with Jackson Kelly to discuss the proposed engagement of Ambassador and the possible sale of Peoples. Jackson Kelly discussed with the directors their duties when considering corporate matters, such as a potential sale of the corporation. In December 2017, but prior to this meeting, the previous investment banking firm contacted Peoples about a possible multi-bank merger, but the board of directors determined that Peoples

32

should continue negotiations to engage Ambassador, rather than the prior investment banking firm, based on its determination that the methods of sale suggested (and ultimately carried out) by Ambassador would enhance the possibility of increasing shareholder value.

The Peoples board of directors met with Jackson Kelly on January 25, 2018, to consider a number of matters. The previous investment banking firm had indicated to Peoples, on a no-name basis, that it might be able to market Peoples to a third party for book value. After careful consideration of this possibility, the board of directors determined to engage Ambassador to act as Peoples financial advisor in connection with a possible sale of Peoples.

With the assistance of Ambassador, Peoples began an auction process to determine and attract potential acquirors of Peoples. During February and March 2018, Peoples populated an electronic data room for potential purchasers. The Peoples board of directors met on March 13, 2018, with Ambassador and Jackson Kelly to review and approve a proposed plan to identify and contact potential acquirors. With the assistance of Ambassador, Peoples identified, and the Peoples board of directors approved, 21 potential purchasers. All potential purchasers were contacted in mid-March of 2018.

Of the 21 potential purchasers, 16 requested additional information. Ten potential purchasers indicated an interest and signed non-disclosure agreements. Two of the ten potential purchasers subsequently determined not to proceed. Between April 2, 2018 and April 11, 2018, Ambassador met with the chief executive officer and the chief financial officer of each of the eight remaining potential purchasers. In late April 2018, three of the eight potential purchasers determined not to go forward, each because Peoples’ market did not fit into each particular entity’s long-term plans.

On May 1, 2018, three of the remaining five potential purchasers submitted letters of interest: Summit, Bidder A and Bidder B. The board of directors of Peoples met with Ambassador on May 7, 2018. At this meeting, Ambassador updated the Peoples directors on the status of the sale process and Ambassador’s meetings with eight financial institutions, three of whom submitted letters of interest. The pricing was 118%, 125% and 127%, respectively, of book value. On May 7, 2018, Bidder A had submitted a revised letter. The board of directors of Peoples considered the three letters and determined that Bidder B’s stock was not as liquid and as freely traded as those of Summit and Bidder A. The Peoples board of directors unanimously decided that Peoples would invite Summit and Bidder A to perform a due diligence review of Peoples. Peoples’ data room was opened to Summit and Bidder A on May 11, 2018.

Summit performed an on-site review of Peoples’ loans on May 17, 2018, and conducted interviews with Peoples’ management on May 23, 2018. On May 23 and May 24, 2018, Bidder A performed an on-site loan review and interviewed Peoples’ management.

On June 6, 2018, each of Summit and Bidder A submitted final letters of interest. Summit increased its offer to the consideration set forth in the merger agreement.

Peoples’ board of directors met with Ambassador and Jackson Kelly on June 11, 2018 to consider the final letters of interest. Ambassador provided a side-by-side comparison of the two letters of interest. After careful consideration and consultation with Ambassador and Jackson Kelly regarding the two letters of interest, the board of directors of Peoples approved the Summit letter of interest and directed Mr. Bowling to execute and deliver the letter to Summit. Bidder A’s letter of interest required downward adjustments of the purchase price, which resulted in Summit’s offer having the better financial terms. The board of directors authorized the management of Peoples to negotiate a definitive agreement with Summit. On June 12, 2018, Peoples executed and delivered the letter of interest to Summit.

The Summit letter of interest included an exclusivity period of 30 days, during which Peoples agreed not to solicit bids or negotiate with any third party. On July 12, 2018, by mutual agreement, the parties extended the exclusivity period through July 26, 2018.

33

During late June and early July of 2018, Peoples conducted a due diligence review of Summit, including a review of documents, a review of public filings and interviews with Summit’s management.

On June 18, 2018, Bowles Rice LLP, counsel for Summit, provided an initial draft of the merger agreement, the director support agreement, and the form of voting agreement to Jackson Kelly. After consultation with Peoples’ management and Ambassador, Jackson Kelly provided initial comments on those agreements on June 22, 2018.

From June 22 through July 22, 2018, Peoples and Summit, with assistance of their respective financial and legal advisors, continued to negotiate the terms of the definitive merger agreement and related documents. In addition, Peoples and Summit and their respective financial and legal advisors continued to discuss various matters related to the proposed combination of Summit and Peoples.

On July 21, 2018, the parties agreed to the calculation of the exchange ratio for converting shares of Peoples common stock into shares of Summit common stock.

On July 23, 2018, the Peoples board of directors held a special meeting to review the terms of the merger agreement, the merger consideration, the various related agreements contemplated by the merger agreement, and the transactions contemplated by the merger agreement, including the merger. The Peoples board of directors received presentations regarding the proposed merger and merger agreement from Ambassador and Jackson Kelly. The board of directors was also briefed on the results of the Peoples’ due diligence review of Summit. Jackson Kelly reviewed the terms of the merger agreement and related agreements, including the bank merger agreement, voting agreements, director support agreements and the proposed employment agreement between Summit Bank and Mr. Bowling. Jackson Kelly again reviewed the legal duties of directors. Ambassador reviewed the financial aspects of the proposed merger and rendered its opinion to the board of directors to the effect that (as of that date and subject to the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Ambassador, as set forth in the opinion) the merger consideration was fair, from a financial point of view, to the holders of Peoples’ common stock. See “The Merger —Opinion of Peoples’ Financial Advisor” on page 39 for more information.

The board of directors deliberated and carefully considered the presentations by Peoples’ financial advisor and legal counsel, as well as the factors described under “Peoples’ Reasons for the Merger; Recommendation of Peoples’ Board of Directors” on page 34. The board of directors also considered the interests of Peoples’ shareholders, employees, and the communities served by Peoples. The board of directors unanimously approved the merger agreement and related agreements and documents. Mr. Bowling indicated that he supported the decision by the board of directors but abstained to the extent that his potential employment agreement with Summit following the merger gave rise to a conflict of interest. The board of directors also approved the submission of the merger agreement to Peoples’ shareholders and recommended that Peoples’ shareholders approve the merger agreement and the merger.

On July 24, 2018, the Summit board of directors approved the merger. Following the meeting of the boards of directors of Peoples and Summit, the merger agreement and related documents were executed after the close of financial markets on July 24, 2018. The parties issued a press release announcing the proposed merger on the evening of July 24, 2018.

Peoples’ Reasons for the Merger; Recommendation of the Peoples Board of Directors

The Peoples board of directors believes that the merger is in the best interest of Peoples and its shareholders. Accordingly, the board of directors has unanimously approved the merger and the merger agreement and unanimously recommends that Peoples’ shareholders vote “FOR” the Peoples merger proposal.

In reaching its decision to approve the merger and the merger agreement and to recommend the approval of the merger agreement and the merger to Peoples’ shareholders, the Peoples board of directors evaluated the

34

merger and the merger agreement in consultation with executive management, its financial advisor, and Jackson Kelly, its legal counsel. The Peoples board of directors carefully considered the terms of the merger agreement and the value of the merger consideration to be received by Peoples’ shareholders and ultimately determined that it was in the best interest of Peoples and its shareholders for Peoples to enter into the merger agreement with Summit. The Peoples board of directors believes that partnering with Summit will maximize the long-term value of its shareholders’ investment in Peoples, and that the merger will provide the combined company with additional resources necessary to compete more effectively in southern West Virginia. The Peoples board of directors believes that Summit common stock is more easily tradeable and is more liquid than Peoples’ common stock. In addition, the Peoples board of directors believes that the customers and communities served by Peoples will benefit from the combined company’s enhanced abilities to meet their banking needs.

In reaching its unanimous decision to approve the merger and the merger agreement and to recommend that Peoples shareholders vote “FOR” the Peoples merger proposal, the Peoples board of directors considered many factors, including, without limitation, the following:

35

The Peoples board of directors also considered a number of potential risks and uncertainties associated with the merger in connection with its deliberation of the proposed transaction, including, but not limited to, the following:

36

The Peoples board of directors also noted that it could terminate the merger agreement in order to concurrently enter into an agreement with respect to an unsolicited acquisition proposal that was received and considered by Peoples in compliance with the non-solicitation provisions of the merger agreement and that would, if consummated, result in a transaction that is more favorable to Peoples shareholders than the merger. This termination right is conditioned on Peoples providing notice of the unsolicited acquisition proposal to Summit, Summit not making a revised offer to Peoples that is at least as favorable as the unsolicited acquisition proposal and Peoples paying a $1,275,000 break-up fee to Summit. The amount of this potential fee was negotiated at arm’s-length and was deemed by Peoples board of directors to be reasonable based upon the break-up fees paid in comparable transactions and the fact that multiple institutions had already been given an opportunity to bid prior to the merger agreement being approved. As of the date of this prospectus and proxy statement, no unsolicited acquisition proposals have been received. See “The Merger Agreement—Acquisition Proposals” on page 65 for more information.

The foregoing discussion of the information and factors considered by the Peoples board of directors is not intended to be exhaustive, but includes the material factors considered by the board of directors. In view of the wide variety and complexity of factors considered in connection with its evaluation of the merger, the Peoples board of directors did not find it practicable to, and did not attempt to, quantify, rank 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 Peoples board of directors did not

37

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 Peoples board of directors based its recommendation on the totality of the information presented.

The Peoples board of directors unanimously recommends that you vote “FOR” the Peoples merger proposal. In considering the recommendation of the Peoples board of directors with respect to the Peoples merger proposal, Peoples shareholders should be aware that Peoples directors and executive officers may have interests in the merger that are different from, or in addition to, those of other shareholders. The board of directors was aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement and the merger and in recommending that the merger agreement and plan of merger be adopted by the shareholders of Peoples. See “The Merger—Interests of Certain Peoples Directors and Executive Officers in the Merger” on page 55.

This summary of the reasoning of Peoples’ board of directors and other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading “Cautionary Statement Regarding Forward-Looking Statements” on page 25.

Summit’s Reasons for the Merger

In reaching its decision to adopt and approve the merger agreement, the merger, the issuance of Summit common stock in connection with the merger and the other transactions contemplated by the merger agreement, the Summit board of directors consulted with Summit management, as well as its legal advisors, and considered a number of factors, including the following material factors:

38

The foregoing discussion of the information and factors considered by the Summit board of directors is not intended to be exhaustive, but includes the material factors considered by the Summit board of directors. In reaching its decision to approve the merger agreement, the merger, the issuance of Summit common stock to Peoples shareholders in connection with the merger, and the other transactions contemplated by the merger agreement, the Summit board of directors did not quantify or assign any relative weights to the factors considered, and individual directors may have given different weights to different factors. The Summit board of directors considered all these factors as a whole, including discussions with, and questioning of, Summit management and Summit’s legal advisors, and overall considered the factors to be favorable to, and to support, its determination.

Opinion of Peoples’ Financial Advisor

Peoples retained Ambassador to act as Peoples’ financial advisor in connection with the possible business combination of Peoples with another party. Ambassador is a nationally recognized investment banking firm whose principal business specialty is financial institutions. In the ordinary course of its investment banking business, Ambassador is regularly engaged in the valuation of financial institutions and their securities in connection with mergers, acquisitions and other corporate transactions.

On July 23, 2018, Ambassador delivered its opinion to Peoples’ board of directors to the effect that, as of such date and based upon and subject to various considerations set forth in the opinion, the merger consideration to be received by the holders of Peoples common stock in the merger was fair to such holders from a financial point of view. Ambassador’s opinion was approved by Ambassador’s Fairness Opinion Committee. Ambassador has consented to the inclusion of its opinion in this prospectus and proxy statement.

The full text of Ambassador’s written opinion to Peoples, which sets forth, among other things, the assumptions made, procedures followed, factors considered and limitations on the review undertaken, is attached as Appendix B to this prospectus and proxy statement and is incorporated by reference in its entirety into this prospectus and proxy statement. Holders of Peoples common stock are encouraged to read the opinion carefully in its entirety. The following summary of Ambassador’s opinion is qualified in its entirety by reference to the full text of such opinion.

Ambassador’s opinion to Peoples’ board of directors was rendered for the benefit of Peoples’ board (in its capacity as such) in connection with its evaluation of the merger. Ambassador’s opinion is not

39

intended and does not constitute a recommendation to any shareholder as to how such shareholder should vote or act with respect to the merger or any matter relating thereto or whether such shareholder should elect to receive the cash consideration or the stock consideration. Ambassador’s opinion does not address the relative merits of the merger as compared to any other transaction or business strategy in which Peoples might engage or the merits of the underlying decision by Peoples to engage in the merger.

No limitations were imposed by Peoples on the scope of Ambassador’s investigation or on the procedures followed by Ambassador in rendering its opinion.

In rendering its opinion, Ambassador:

In rendering Ambassador’s opinion, Ambassador also relied upon and assumed, without independent verification, the accuracy, reasonableness and completeness of the information provided to Ambassador by or on

40

behalf of Peoples and Summit, referred to as the materials received and publicly available information used in Ambassador’s analyses. Ambassador does not assume any responsibility for the accuracy, reasonableness and completeness of any of the foregoing materials received and publicly available information or for the independent verification thereof. Further, Ambassador relied on the assurances of managements of Peoples and Summit that they were not aware of any facts or circumstances that would make any of the materials received inaccurate or misleading. With respect to the financial projections and forecasts for Peoples and research analysts’ estimates and pro forma tangible book value and other assumptions for Summit referred to above, Ambassador assumed, with Peoples’ consent, that they have been reasonably prepared on bases reflecting (or, in the case of research analysts’ estimates, are consistent with) the best currently available estimates and judgments of the respective managements of Peoples and Summit, as the case may be, as to the future financial performance of Peoples and Summit and the other matters covered thereby and that the financial results reflected in such projections, forecasts, estimates and assumptions would be realized in the amounts and at the times projected. Ambassador assumed no responsibility for and express no view as to any of the foregoing information reviewed by Ambassador or the assumptions on which they were based.

Ambassador is not an expert in the evaluation of deposit accounts or loan, mortgage or similar portfolios or allowances for losses with respect thereto and Ambassador was not requested to, and Ambassador did not, conduct a review of individual credit files or loan, mortgage or similar portfolios. Ambassador assumed no responsibility for and expressed no view as to the adequacy or sufficiency of allowances for losses or other matters with respect thereto and Ambassador assumed that each of Peoples and Summit has, and the pro forma combined company will have, appropriate reserves to cover any such losses. Ambassador did not conduct any independent valuation or appraisal of any of the assets or liabilities (contingent or otherwise) of Peoples, Summit or any other party, and Ambassador was not furnished with any such valuation or appraisal.

Ambassador’s opinion was based on conditions as they existed and the information Ambassador received, as of the date of Ambassador’s opinion. Ambassador does not have any obligation to update, revise or reaffirm its opinion. Ambassador expressed no opinion as to the actual value of Summit common stock when issued in the merger or the prices at which Summit common stock might trade at any time.

In rendering its opinion, Ambassador assumed, with Peoples’ consent, that the merger and related transactions would be consummated on the terms described in the merger agreement, without any waiver or modification of any material terms or conditions. Ambassador also assumed, with Peoples’ consent, that, in the course of obtaining the necessary governmental, regulatory and other third-party approvals, consents and releases for the merger, including with respect to any divestiture or other requirements, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on Peoples, Summit or the merger (including the contemplated benefits thereof). Ambassador also assumed, with Peoples’ consent, that the final merger agreement would not differ from the version reviewed by Ambassador in any respect material to Ambassador’s analyses or opinion. Ambassador further assumed, with Peoples’ consent, that the merger will qualify for U.S. federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Code. In addition, Ambassador assumed, with Peoples’ consent, any adjustment to the merger consideration provided for in the merger agreement and the potential special cash distribution that may be made to holders of Peoples common stock immediately prior to the closing date of the merger will not be in any respect material to Ambassador’s analyses or opinion.

Ambassador expressed no view or opinion as to any terms or other aspects (other than the merger consideration to the extent expressly specified herein) of the merger or any related transaction, including, without limitation, the form of the merger consideration or the allocation thereof between cash and Summit common stock, the relative fairness of the cash consideration and the stock consideration, or any adjustment to the merger consideration or the potential special cash distribution referred to above. Ambassador’s opinion did not address the relative merits of the merger as compared to any other transaction or business strategy in which Peoples might engage or the merits of the underlying decision by Peoples to engage in the merger. Ambassador expressed no opinion with respect to the fairness of the amount or nature of any compensation to any of the officers,

41

directors, or employees of any party to the merger, or any class of such persons, relative to the merger consideration or otherwise.

In performing its analyses, Ambassador made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters, which are beyond the control of Ambassador, Peoples and Summit. Any estimates contained in the analyses performed by Ambassador are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by these analyses. Additionally, estimates of the value of businesses or securities do not purport to be appraisals or to reflect the prices at which such businesses or securities might actually be sold. Accordingly, these analyses and estimates are inherently subject to substantial uncertainty. In addition, Ambassador’s opinion was among several factors taken into consideration by the Peoples’ board of directors in making its determination to approve the merger agreement and the merger. Consequently, the analyses described below should not be viewed as determinative of the decision of the Peoples board of directors with respect to the fairness of the merger consideration. The type and amount of consideration payable in the merger were determined through negotiation between Peoples and Summit and the decision of Peoples to enter into the merger agreement was solely that of the Peoples board of directors.

Selected Implied Transaction Ratios for the Merger

Based on Peoples’ financial information as of March 31, 2018, for the twelve months ended March 31, 2018 or for the three months ended March 31, 2018 (annualized), Ambassador calculated the following transaction ratios using an implied per share value of the merger consideration of $47.00, or an implied transaction value of approximately $25.476 million:

The following is a summary of the material financial analysis presented by Ambassador to Peoples’ board in connection with rendering its opinion. This summary is not a complete description of the analyses and procedures performed by Ambassador in the course of arriving at its opinion. The financial analyses summarized below include information presented in tabular format. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex analytical process involving various determinations as to appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, Ambassador did not attribute any particular weight to any analysis or factor that it considered, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, Ambassador believes that its analyses and the summary of its analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on the information presented below in tabular format, without considering all analyses and factors or the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying its analyses and opinion. No company, transaction or business used in Ambassador’s analyses for comparative purposes is identical to Peoples, Summit or the proposed merger and an evaluation of the results of those analyses is not entirely mathematical.

Selected Companies Analysis of Peoples

Ambassador performed a selected companies analysis by comparing the financial performance of Peoples with those of the following nine selected publicly traded institutions, referred to as the Peoples comparable

42

institutions, that were headquartered in Kentucky, Ohio, Pennsylvania, Tennessee, Virginia or West Virginia (excluding the Philadelphia area and Northern Virginia, which is adjacent to the District of Columbia), were not mutual institutions or merger or acquisition targets and had assets under $400 million, average one-year daily trading volume greater than 100, nonperforming assets, referred to as NPAs, to assets ratios less than 2%, and returns on equity between 2% and 8% and by also reviewing the stock performance of the Peoples comparable institutions:

Discounted Dividend Analysis of Peoples

Ambassador performed a discounted dividend analysis to estimate a range for the implied equity value of Peoples common stock. In this analysis, Ambassador assumed discount rates of 10%, 12% and 14% and calculated terminal values of 100% and 110% of estimated tangible book value at the end of five years. Ambassador used financial projections and forecasts for Peoples provided to Ambassador by the management of Peoples. This analysis indicated an implied present value range of Peoples common stock of $25.46 per share to $32.65 per share, which are 13.7X and 17.6X, respectively, of Peoples’ 2018 budgeted earnings per share and 68% and 87%, respectively, of Peoples tangible book value as of March 31, 2018.

Selected Transactions Analysis of Peoples

Ambassador performed a selected transactions analysis by reviewing the following information for purposes of comparison with selected implied transaction ratios for the merger:

Selected Companies Analysis of Summit

Ambassador performed a selected companies analysis by comparing the financial and stock performance of Summit with those of the following twenty-five selected publicly traded institutions, referred to as the Summit comparable institutions, that were headquartered in Kentucky, Maryland, Pennsylvania, Tennessee, Virginia or West Virginia (excluding the Washington DC metropolitan markets and Philadelphia metropolitan markets), were not mutual institutions or merger or acquisition targets, that had assets between $1 billion and $4 billion and average one-year daily trading volume greater than 1,000 and that were traded on the NYSE or NASDAQ:

Ambassador also reviewed the historical stock price performance of Summit relative to the Summit comparable institutions and selected stock indices, as indicated in the following tables:

Relative to Comparable Institutions and Selected Indices

Financial Impact Analysis on Summit

Ambassador also conducted a financial impact analysis assuming that the merger will close at the end of the third quarter of 2018. Ambassador used historical financial data as of March 31, 2018, or for the three months ended March 31, 2018, financial projections and forecasts for Peoples provided to Ambassador by the management of Peoples, median research analysts’ estimates for Summit, and projected cost savings anticipated by the management of Summit to be realized from the merger. Ambassador also incorporated other pro forma assumptions as provided by Summit. The analysis indicated that the merger could be dilutive to tangible book value per share as of September 30, 2018 by approximately 0.7% and could be accretive to earnings per share for the nine months ended September 30, 2018, annualized by approximately 2.2%. All of the results of Ambassador’s financial impact analysis may vary materially from the actual results achieved by Summit.

Other Disclosures

Ambassador, as part of its financial advisory business, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions and valuations for corporate and other purposes. Peoples selected Ambassador to act as a financial advisor and to provide a fairness opinion based on Ambassador’s experience, including in connection with mergers and acquisitions of commercial banks and bank holding companies.

Peoples has agreed to pay Ambassador a fee for its services totaling approximately $306,000, a portion of which fee became payable upon presentation of Ambassador’s opinion and approximately $241,000 of Ambassador’s fee is contingent upon the closing of the merger. In addition, portions of Ambassador’s fee became payable upon the signing of Ambassador’s engagement agreement and upon approval by Peoples of a confidential information memorandum regarding Peoples that was provided to third parties. Peoples has also agreed to reimburse Ambassador’s out-of-pocket expenses incurred in connection with its engagement and to indemnify Ambassador against certain liabilities arising out of the performance of its obligations under the engagement letter.

Over the two years preceding the date of Ambassador’s opinion, Ambassador provided investment banking or other consulting services to Peoples for which Ambassador received compensation from Peoples. Ambassador provided certain valuation advisory services to Peoples in 2017. Over the two years preceding the date of Ambassador’s opinion, Ambassador did not provide investment banking or other consulting services to Summit

49

for which Ambassador received compensation from Summit. In the future, Ambassador may pursue the opportunities to provide investment banking and other consulting services to Peoples and Summit.

Ambassador’s fairness committee approved the issuance of its opinion letter dated July 23, 2018.

Certain Peoples Unaudited Prospective Financial Information

Peoples does not as a matter of course make public projections as to future performance, revenues, earnings or other financial results due to, among other reasons, the inherent uncertainty of the underlying assumptions and estimates. However, Peoples is including in this prospectus and proxy statement certain unaudited internal financial forecasts that were made available to Ambassador, as Peoples’ financial advisor, for purposes of the discounted dividend analysis and the financial impact analysis on Summit performed by Ambassador in connection with its opinion to the Peoples board of directors. The inclusion of these financial forecasts should not be regarded as an indication that any of Peoples, Summit or Ambassador, their respective representatives or any other recipient of this information considered, or now considers, it to be necessarily predictive of actual future results or that it should be construed as financial guidance, and it should not be relied on as such.

The unaudited internal financial forecasts included below were prepared solely for the internal use of Peoples and were provided to Ambassador for purposes of its discounted dividend analysis of Peoples and its financial impact analysis on Summit and are subjective in many respects. The unaudited internal financial forecasts reflect numerous estimates and assumptions made with respect to business, economic, market, competition, regulatory and financial conditions and matters specific to Peoples’ business, all of which are difficult to predict and many of which are beyond Peoples’ control. The unaudited internal financial forecasts reflect both assumptions as to certain business decisions that are subject to change and, in many respects, subjective judgment, and thus are susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. Peoples can give no assurance that the unaudited internal financial forecasts and the underlying estimates and assumptions will be realized. In addition, since the unaudited internal financial forecasts cover multiple years, such forecasts by their nature becomes subject to greater uncertainty with each successive year. Actual results may differ materially from those set forth below, and important factors that may affect actual results and cause the unaudited internal financial forecasts to be inaccurate include, but are not limited to, risks and uncertainties relating to Peoples’ business, industry performance, general business and economic conditions, customer requirements, competition and adverse changes in applicable laws, regulations or rules. For other factors that could cause actual results to differ, please see the sections entitled “Risk Factors” and “Cautionary Statement Concerning Forward-Looking Statements” beginning on page 17 and page 25, respectively, of this prospectus and proxy statement.

The unaudited internal financial forecasts were not prepared with a view toward public disclosure, nor were they prepared with a view toward compliance with GAAP, published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. In addition, the unaudited internal financial forecasts require significant estimates and assumptions that make them inherently less comparable to the similarly titled GAAP measures in Peoples’ historical GAAP financial statements. Neither Peoples’ independent registered public accounting firm, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the unaudited internal financial forecasts contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability.

Furthermore, the unaudited internal financial forecasts do not take into account any circumstances or events occurring after the date they were prepared. Peoples can give no assurance that, had the unaudited internal financial forecasts been prepared either as of the date of the merger agreement or as of the date of this prospectus and proxy statement, similar estimates and assumptions would be used. Peoples does not intend to, and disclaims any obligation to, make publicly available any update or other revision to the unaudited internal financial forecasts to reflect circumstances existing since their preparation or to reflect the occurrence of unanticipated

50

events, even in the event that any or all of the underlying assumptions are shown to be in error, or to reflect changes in general economic or industry conditions. The unaudited internal financial forecasts do not take into account the possible financial and other effects on either Peoples or Summit, as applicable, of the merger and do not attempt to predict or suggest future results of the combined company. The unaudited internal financial forecasts do not give effect to the impact of negotiating or executing the merger agreement, the expenses that may be incurred in connection with consummating the merger, the potential synergies that may be achieved by the combined company as a result of the merger, the effect of any business or strategic decision or action that has been or will be taken as a result of the merger agreement having been executed, or the effect on either Peoples or Summit, as applicable, of any business or strategic decisions or actions that would likely have been taken if the merger agreement had not been executed, but which were instead altered, accelerated, postponed or not taken in anticipation of the merger. Further, the unaudited internal financial forecasts do not take into account the effect on either Summit or Peoples, as applicable, of any possible failure of the merger to occur. None of Peoples, Summit or Ambassador or their affiliates, officers, directors, advisors or other representatives has made, makes or is authorized in the future to make any representation to any shareholder of Peoples, shareholder of Summit or other person regarding Peoples’ ultimate performance compared to the information contained in the unaudited internal financial forecasts or that the projected results will be achieved.

The inclusion of the unaudited internal financial forecasts herein should not be deemed an admission or representation by Summit or Peoples that such forecasts are viewed as material information of Peoples, particularly in light of the inherent risks and uncertainties associated with such forecasts. The unaudited internal financial forecasts included below are not being included to influence your decision whether to vote for the merger and the transactions contemplated in connection with the merger, but are being provided solely because they were made available to Peoples’ financial advisor, Ambassador, and Summit in connection with the merger.

In light of the foregoing, and considering that the Peoples special meeting will be held several months after unaudited internal financial forecasts were prepared, as well as the uncertainties inherent in any forecasted information, Peoples shareholders are cautioned not to place unwarranted reliance on such information.

The following unaudited internal financial forecasts were prepared by Peoples’ management and were reviewed and used by Ambassador for purposes of the discounted dividend analysis of Peoples and the financial impact analysis on Summit performed in connection with its opinion to the Peoples board of directors:

Certain Summit Unaudited Prospective Financial Information

information, Peoples shareholders are cautioned not to place unwarranted reliance on such information, and Summit urges all Peoples shareholders to review Summit’s most recent SEC filings for a description of Summit’s reported financial results. See “Where You Can Find More Information” on page 91 of this prospectus and proxy statement.

The following unaudited pro forma financial information reflecting the effect of the merger was provided by senior management of Summit and was reviewed and used by Ambassador in connection with the proposed merger for purposes of the financial impact analysis on Summit performed by Ambassador in connection with its opinion to the Peoples board of directors: future pre-tax cost savings equal to 40% of Peoples’ pre-merger non-interest expense.

Public Trading Markets

Summit common stock trades on NASDAQ under the symbol “SMMF.” There is no established public trading market for Peoples common stock. Before the effective time of the merger, Summit has agreed to use its reasonable best efforts to cause the shares of Summit common stock to be issued in the merger to be approved for listing on NASDAQ. The listing of the shares of Summit common stock is also a condition to the consummation of the merger.

Dissenters’ or Appraisal Rights

If the merger is consummated, holders of record of Peoples common stock who follow the procedures specified by Sections 31D-13-1301 through 31D-13-1331 of the WVBCA will be entitled to determination and payment in cash of the “fair value” of their stock (as determined immediately before the effective time of the merger), plus accrued interest from the effective time of the merger until the date of payment. Peoples shareholders who elect to follow these procedures are referred to as dissenting shareholders.

A vote in favor of the merger agreement by a holder of Peoples common stock will result in a waiver of the shareholder’s right to demand payment for his or her shares as dissenting shareholders.

The following summary of the provisions of Sections 31D-13-1301 through 31D-13-1331 of the WVBCA is not intended to be a complete statement of such provisions, the full text of which is attached as Appendix C to this prospectus and proxy statement, and is qualified in its entirety by reference thereto.

A holder of Peoples common stock electing to exercise appraisal rights must deliver to Peoples a written notice of dissent stating that he or she intends to demand payment for his or her shares if the merger is consummated. This notice must be delivered before the vote is taken. The dissenting shareholder must not vote, or cause or permit to be voted, any of his or her shares in favor of the proposed transaction or, if action is taken by written consent of the shareholders, must not sign a consent in favor of or otherwise approve the proposed transaction. If the dissenting shareholder fails to comply with these requirements, he or she will not be entitled to appraisal rights. The “fair value” of the shares as defined above is determined using customary and current valuation concepts and techniques generally employed for similar businesses in the context of the transaction requiring appraisal and without discounting for lack of marketability or minority status. It should be noted that investment banker opinions as to the fairness from a financial point of view of the consideration payable in a transaction such as the proposed merger are not opinions as to, and do not address, “fair value” under the WVBCA.

Within 10 days after the effective time of the merger, Summit, as surviving corporation of the merger, will give written notice of the effective time of the merger by certified mail to each shareholder who filed a written notice of dissent. The notice will provide (i) where demand for payment must be sent and where and when share certificates, if any, must be deposited, (ii) supply a form for demanding payment in compliance with Section 31D-13-1322 of the WVBCA, (iii) set a date by which Summit must receive the demand for payment,

53

which may not be less than 40 nor more than 60 days after the date the notice is sent, (iv) state Summit’s estimated fair value of the shares; (v) state that the shareholder shall be deemed to have waived the right to demand payment with respect to the shares unless the form is received by Summit by such specified date, (vi) state that, if requested in writing, Summit will provide to the requesting shareholder within 10 days after the date set forth in subsection (iii) above, the number of shareholders that return a form demanding payment by the specified date and the total number of shares owned by such shareholders, (vii) state the date by which the notice to withdraw must be received, which date must be within 20 days after the date set forth in subsection (iii) above, and (viii) be accompanied by a copy of Sections 31D-13-1301 through 31D-13-1331 of the WVBCA, inclusive.

Within the time period set forth in the notice, the dissenting shareholder must (i) sign and return the form sent by Summit demanding payment of the fair value of his or her shares, (ii) certify that the shareholder acquired beneficial ownership of the shares before the date required as set forth in the notice, and (iii) deposit his or her share certificates, if any, in accordance with the terms of the notice. Once the shareholder deposits his or her share certificates, or, in the case of uncertificated shares makes demand for payment, that shareholder loses all rights as a shareholder, unless he or she withdraws from the appraisal process by the date described in subsection (vii) of the immediately preceding paragraph.

Within 30 days after the receipt of the dissenting shareholder’s demand for payment, Summit, as the surviving corporation, will pay each dissenting shareholder who complied with the required procedures the amount it estimates to be the fair value of the dissenting shareholder’s shares, plus accrued interest. Summit will include along with the payment to each dissenting shareholder (i) a balance sheet as of the end of a fiscal year ending not more than 16 months before the date of payment, a statement of income for that year, a statement of changes in the shareholders’ equity for that year, or, where such financial statements or not reasonably available, then such reasonably equivalent financial information, and the latest available interim financial statements, if any, and a report by the public accountant or statement by the president or other person responsible for Peoples’ accounting records that complies with Section 31D-13-1324(b) of the WVBCA, (ii) a statement of Summit’s estimate of the fair value of the shares which shall be equal to or exceed the estimate of the fair value provided in the notice, and (iii) a statement of the dissenting shareholder’s right to demand further payment under 31D-13-1326 of the WVBCA and that if any such shareholder does not do so within the period specified, such shareholder shall be deemed to have accepted such payment in full satisfaction of Summit’s obligations under the WVBCA.

Following receipt of payment, a dissenting shareholder, within 30 days, may send Summit notice containing such shareholder’s own estimate of fair value and accrued interest, and demand payment for that amount less the amount received pursuant to Summit’s payment of fair value to such shareholder. This right is waived if the dissenting shareholder does not make written demand within 30 days of Summit’s payment for the shareholder’s shares. If a demand for payment remains unsettled, Summit will petition the court to determine fair value and accrued interest. If Summit fails to commence an action within 60 days following the receipt of a dissenting shareholder’s demand, Summit will pay each dissenting shareholder whose demand remains unsettled the amount demanded by each dissenting shareholder, plus interest.

All dissenting shareholders whose demands remain unsettled, whether residents of West Virginia or not, must be made parties to the action and the court will render judgment for the fair value of their shares. Each party must be served with the petition. The judgment shall include payment for the amount, if any, by which the court finds the fair value of such shares, plus interest, exceeds the amount already paid. If the court finds that the demand of any dissenting shareholder for payment was arbitrary, vexatious or otherwise not in good faith, the court may assess all court costs, including reasonable fees of appraisers appointed by the court, against such shareholder. Otherwise the court costs will be assessed against Summit. In addition, reasonable fees and expenses of counsel and experts will be determined by the court and may be assessed against Summit if the court finds that it did not substantially comply with the requirements of the West Virginia appraisal rights statute or that it acted arbitrarily, vexatiously, or not in good faith with respect to the rights granted to dissenters under West Virginia law.

54

If you are a holder of shares and you wish to seek appraisal rights, you are urged to review the applicable West Virginia statutes attached to this prospectus and proxy statement as Appendix C.

Interests of Certain Peoples Directors and Executive Officers in the Merger

In considering the recommendations of the Peoples board of directors that Peoples shareholders vote in favor of the Peoples merger proposal, Peoples shareholders should be aware that Peoples directors and executive officers may have interests in the merger that differ from, or are in addition to, their interests as shareholders of Peoples. The Peoples board of directors was aware of these interests and took them into account in its decision to approve and adopt the merger agreement and the transactions contemplated by the merger agreement, including the merger.

Employment Agreements for Peoples Executive Officers

Peoples previously had no written employment agreements for any executive officers. Peoples’ President and Chief Executive Officer, Ronald L. Bowling, is an at-will employee with no written employment agreement, with a current annual salary of $132,409.23, plus customary health, welfare and fringe benefits, participation in a 401(k) retirement plan and a defined benefit pension plan that was frozen and closed to new accruals and participants effective March 31, 2016. Mr. Bowling will not receive any severance or change of control payments as a result of the merger.

Employment with Summit Community Bank Following the Merger

It is anticipated that Mr. Ronald L. Bowling will enter into an employment agreement with Summit Community Bank, effective upon the effective time, with a one-year term. Mr. Bowling is expected to be Market President of Summit Community Bank. Mr. Bowling’s base salary will be at least $135,000 annually.

In addition, upon the effective time, Mr. Bowling will receive a retention bonus of $100,000. If Mr. Bowling remains continuously employed with Summit Community Bank through the end of the first year after the effective time, referred to as the one year period, he will receive, within 30 days after the end of the one year period, an additional retention bonus equal to $100,000, referred to as the one year payment, provided that as an additional precondition to Summit Community Bank’s obligation to pay the one year payment, Mr. Bowling signs and delivers an irrevocable release of claims no later than 30 days after the end of the one year period. While Mr. Bowling is not expected to continue employment with Summit Community Bank beyond the one year period, the requirement of a release of claims as a precondition to receipt of the one year payment is inapplicable if Mr. Bowling does continue employment with Summit Community Bank beyond the end of the one year period.

In the event, however, that Mr. Bowling’s employment with Summit Community Bank is terminated due to death, disability or termination by Summit Community Bank without cause, before one year after the effective time, the one year payment will instead be paid within 30 days after such earlier termination, and if such earlier termination is by Summit Community Bank without cause, as an additional precondition to Summit Community Bank’s obligation to pay the one year payment, Mr. Bowling or his estate is required to sign and deliver an irrevocable release of claims no later than 30 days after such termination without cause. Mr. Bowling forfeits the one year payment if he is not continuously employed through the end of the one year period due to resignation or termination by Summit for cause prior to the end of the one year period.

Mr. Bowling will participate in the employee benefit plans, programs and arrangements of Summit Community Bank in the same manner as similarly situated Summit Community Bank employees.

In addition to the one year payment, if Mr. Bowling’s employment is terminated by Summit Community Bank without cause prior to the end of the one year period, Mr. Bowling shall be entitled to receive any wages, including accrued benefits, that have been earned by Mr. Bowling through the effective date of such termination

55

and he shall be entitled to receive a lump sum cash payment equal to the amount of base salary that he would have received between (i) the effective date of such termination without cause and (ii) the last day of the one year period, such lump sum cash payment is referred to as the severance payment, provided that as an additional precondition to Summit Community Bank’s obligation to pay the severance payment, Mr. Bowling is required to sign and deliver the irrevocable release of claims no later than 30 days after such termination of employment by Summit Community Bank prior to the end of the one year period. Payments to Mr. Bowling are subject to any applicable timing delays under Internal Revenue Code Section 409A, if any such delays are applicable and required for compliance with Code Section 409A.

Mr. Bowling’s agreement will include customary non-compete, non-solicit and confidentiality covenants.

Peoples Retirement Benefits

In connection with the merger, it is anticipated that all participants in the First Peoples Bank of Mullens 401(k) Plan and the First Peoples Bank, Inc. Defined Benefit Pension Plan, including Mr. Bowling and all Peoples executives who are participants, will be fully vested in their accounts.

Accounting Treatment of the Merger

The merger will be accounted for using acquisition accounting in accordance with U.S. generally accepted accounting principles, for accounting and financial reporting purposes. Under acquisition accounting, the assets (including identifiable intangible assets) and liabilities (including executory contracts and other commitments) of Peoples as of the effective time of the merger will be recorded at their respective fair values and added to those of Summit. Any excess of purchase price over the fair values is recorded as goodwill. Consolidated financial statements of Summit issued after the merger would reflect these fair values and would not be restated retroactively to reflect the historical consolidated financial position or results of operations of Peoples.

56

THE MERGER AGREEMENT

The following is a summary of the material provisions of the merger agreement. This summary is qualified in its entirety by reference to the merger agreement, a copy of which is included as Appendix A to this prospectus and proxy statement and is incorporated herein by reference. This summary may not contain all of the information about the merger agreement that may be important to you. You should read the merger agreement carefully and in its entirety, as it is the legal document governing the merger.

Terms of the Merger

Each of the Summit board of directors and the Peoples board of directors has approved the merger agreement, which provides for the merger of Peoples with and into merger sub, a limited liability company and wholly-owned subsidiary of Summit Community Bank, with merger sub as the surviving entity in the merger. Immediately following the merger, merger sub will be liquidated so that Summit Community Bank will own all of the outstanding shares of Peoples’ wholly owned banking subsidiary First Peoples Bank. Immediately following the liquidation of merger sub, First Peoples Bank will be merged with and into Summit Community Bank, or the bank merger, with Summit Community Bank surviving as the surviving bank in the bank merger.

The Summit Community Bank articles of incorporation and the Summit Community Bank bylaws as in effect immediately prior to the completion of the merger will be the articles of incorporation and bylaws of the surviving corporation.

Merger Consideration

Under the terms of the merger agreement, each share of Peoples common stock outstanding immediately prior to the effective time of the merger (excluding dissenting shares) will be converted into the right to receive:

However, the aggregate number of Peoples shares that will be converted for cash consideration will be equal to 271,020 shares, or approximately 50% of the merger consideration, and the aggregate per share cash consideration will be equal to $12,737,940, or approximately 50% of the merger consideration. The remaining 50% of the merger consideration will be stock consideration consisting of an aggregate of 271,021 shares of Peoples common stock converting to a maximum of 465,967 shares of Summit common stock after applying the exchange ratio. Accordingly, elections by Peoples shareholders to receive a particular form of consideration, whether cash or shares of Summit common stock, will be prorated as necessary to cause the total amount of cash payable and shares issued by Summit in the merger to equal, as closely as possible, the total of cash and stock consideration discussed above.

Based upon the closing sale price of the Summit common stock on the Nasdaq Capital Market of $24.24 on September 21, 2018, the most current date available prior to the printing of this prospectus and proxy statement, each common share of Peoples will be entitled to be exchanged for total stock consideration equal to $41.48 per share.

No fractional shares of Summit common stock will be issued in connection with the merger. Instead, Summit will make to each Peoples shareholder who would otherwise receive a fractional share of Summit common stock a cash payment (rounded to the nearest whole cent) equal to (i) such fractional part of a share of Summit common stock multiplied by (ii) $47.00, the per share cash consideration. We refer to the per share stock consideration, the per share cash consideration and cash in lieu of any fractional shares, collectively, as the merger consideration.

A Peoples shareholder also has the right to obtain the fair value of his, her or its shares of Peoples common stock in lieu of receiving the merger consideration by strictly following the appraisal procedures under the WVBCA. Shares of Peoples common stock outstanding immediately prior to the effective time of the merger and which are held by a shareholder who does not vote to approve the merger agreement and who properly demands the fair value of such shares pursuant to, and who complies with, the appraisal procedures under the WVBCA are referred to as “dissenting shares.” See “The Merger—Dissenters’ or Appraisal Rights” on page 53.

57

If Summit changes the number of shares of Summit common stock outstanding prior to the effective time of the merger as a result of a stock split, stock combination, stock dividend or similar recapitalization with respect to the Summit common stock and the record date for such corporate action is prior to the effective time of the merger, then the per share stock consideration shall be proportionately adjusted as necessary to preserve the relative economic benefit to Summit and Peoples.

The value of the shares of Summit common stock to be issued to Peoples shareholders in the merger will fluctuate between now and the closing date of the merger. We make no assurances as to whether or when the merger will be completed, and you are advised to obtain current sale prices for the Summit common stock. See “Risk Factors—Because the sale price of the Summit common stock may fluctuate, you cannot be sure of the value of the merger consideration that you will receive in the merger.”

Shareholders’ Equity

As of the last day of the calendar quarter immediately preceding the effective time, if Peoples’ shareholders’ equity, as presented on Peoples’ balance sheet, determined in accordance with GAAP (including adjustments for the defined benefit pension plan) and adjusted to exclude any after-tax net unrealized gains or losses on available-for-sale securities included in accumulated other comprehensive income, referred to as the adjusted shareholders’ equity, is less than $20,100,000, then the aggregate value of the merger consideration shall be reduced one dollar for every dollar by which the adjusted shareholders’ equity is less than $20,100,000. In calculating the adjusted shareholders’ equity, all costs and expenses of Peoples associated with the merger shall have been paid or accrued prior to the effective time, including but not limited to, legal, accounting, brokerage, advisory or consulting fees, early termination fees for data processing or other contractual arrangement and any change-in-control or similar payments (to employees or otherwise). Any reduction in the merger consideration shall be allocated between the cash consideration and the stock consideration proportionately in accordance with the limitations discussed below.

Peoples may distribute, in a lump sum, to the Peoples shareholders, immediately prior to the effective time, a cash distribution per share, referred to as the special distribution, in the amount by which adjusted shareholders’ equity exceeds $21,100,000 as of the last day of the calendar quarter immediately preceding the effective time, if any, divided by the number of shares of Peoples, provided that such distribution does not cause the merger to be considered something other than a tax-free reorganization in accordance with the Code and any regulations promulgated thereunder. Accordingly, the merger agreement provides that the aggregate amount of the special distribution shall not exceed (i) when combined with amounts paid to dissenting shareholders, Peoples assets used to pay its reorganization expenses and all redemptions and distributions (except for normal regular dividends) paid by Peoples immediately preceding the merger, an amount that would result in either (A) less than 90% of the fair market value of net assets of Peoples or (B) less than 70% of the fair market value of gross assets held by Peoples immediately prior to the special distribution, being transferred to merger sub in the merger, or (ii) when combined with the cash consideration, 60% of the value of the merger consideration (determined by adding amounts paid to dissenting shareholders to the merger consideration and the aggregate amount of the special distribution). If Peoples’ adjusted shareholders’ equity does not exceed $21,100,000, then the special distribution shall not occur.

Election Procedures; Surrender of Peoples Stock Certificates

An election form must be mailed at least 30 days prior to the anticipated effective time of the merger, or the mailing date. The election form (together with transmittal materials) will be mailed to Peoples shareholders of record as of five business days prior to the mailing date, referred to as the election form record date. Peoples shareholders should carefully review and follow the instructions that will be included with the election form. Each holder of Peoples common stock must complete and return the election form to the exchange agent by 5:00 p.m. Eastern Time on the 25th day following the mailing date of the election form to Peoples shareholders. The election form must be accompanied by the stock certificates representing the Peoples common stock held by the Peoples shareholder.

58

Election forms may be revoked or amended at any time prior to the election deadline.

Summit has appointed Computershare as the exchange agent under the merger agreement. The exchange agent will mail to each holder of record of Peoples common stock the election form along with instructions for completing the election form and delivering back to the exchange agent the completed election form along with the stock certificates representing the shares of Peoples common stock held by the shareholder.

Summit shall make available an election form to all persons who become holders (or beneficial owners) of Peoples common stock between the election form record date and close of business on the business day prior to the election deadline, and Peoples shall provide to the exchange agent all information reasonably necessary for it to perform as specified herein. Peoples acknowledges that no deadlines for mailing election forms contained in the merger agreement shall be applicable to such shareholders and that the election requests of such shareholders need not be honored.

Within five business days after the election deadline, unless the effective time has not yet occurred, in which case as soon thereafter as practicable, Summit shall cause the exchange agent to effect the allocation among the holders of Peoples common stock of rights to receive the stock consideration or the cash consideration in the merger in accordance with the election forms, subject to the adjustments addressed in the merger agreement and set out below.

Upon surrender to the exchange agent of the certificate(s) representing his, her or its shares of Peoples common stock, accompanied by a properly completed and executed election form, a Peoples shareholder will be entitled to receive after the effective time of the merger the merger consideration (including any cash in lieu of fractional shares). Until surrendered, each such certificate will represent after the effective time of the merger, for all purposes, only the right to receive, without interest, the merger consideration (including any cash in lieu of fractional shares) and any dividends or distributions to which such holder is entitled pursuant to the merger agreement.

No dividends or other distributions with respect to Summit common stock after completion of the merger will be paid to the holder of any unsurrendered Peoples stock certificates with respect to the shares of Summit common stock represented by those certificates until those certificates have been properly surrendered. Subject to applicable abandoned property, escheat or similar laws, following the proper surrender of any such previously unsurrendered Peoples stock certificate, the holder of the certificate will be entitled to receive, without interest: (i) any cash payable with respect to a fractional share of Summit common stock to which such holder is entitled to pursuant to the merger agreement, if applicable, and the amount of unpaid dividends or other distributions with a record date after the effective time of the merger payable with respect to the whole shares of Summit common stock represented by that certificate; and (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to shares of Summit common stock represented by that certificate with a record date after the effective time of the merger (but before the date on which the certificate is surrendered) and with a payment date subsequent to the issuance of the shares of Summit common stock issuable in exchange for that certificate.

Shares of Summit common stock and cash in lieu of any fractional shares may be issued or paid in a name other than the name in which the surrendered Peoples stock certificate is registered if: (i) the certificate surrendered is properly endorsed or otherwise in a proper form for transfer; and (ii) the person requesting the payment or issuance pays any transfer or other similar taxes due or establishes to the satisfaction of Summit that such taxes have been paid or are not applicable.

None of Summit, the exchange agent or any other person will be liable to any former Peoples shareholder for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

59

In the event any Peoples stock certificate is lost, stolen or destroyed, in order to receive the merger consideration (including cash in lieu of any fractional shares), the holder of that certificate must provide an affidavit of that fact and, if reasonably required by the exchange agent, post a bond in such amount as the exchange agent determines is reasonably necessary to indemnify it against any claim that may be made against it with respect to that certificate.

The total number of shares of Peoples common stock to be converted into the right to receive the stock consideration shall be equal to 271,021 shares of Peoples common stock, converting to a maximum of 465,967 shares of Summit common stock or approximately 50% of the merger consideration, and the total number of shares of Peoples common stock to be converted into the right to receive the cash consideration shall be equal to 271,020 shares of Peoples common stock, for total cash consideration of approximately $12,737,940.

Stock Consideration Proration.

If the aggregate number of shares of Peoples common stock with respect to which stock election shares and mixed stock shares shall have been validly made, referred to as the stock election number, exceeds the maximum stock consideration, then all cash election shares and all no election shares of each holder thereof shall be converted into the right to receive the cash consideration, and stock election shares of each holder thereof will be converted into the right to receive the stock consideration in respect of that number of stock election equal to the product obtained by multiplying (x) the number of stock election shares held by such holder by (y) a fraction, the numerator of which is the maximum stock consideration and the denominator of which is the stock election number, with the remaining number of such holder’s stock election shares being converted into the right to receive the cash consideration.

By way of example, if there are a total of 300,000 stock election shares, thus exceeding the maximum stock consideration of 271,021, by 28,979, then the shares of Peoples common stock held by a shareholder with 5,000 stock election shares would be exchanged in the following manner:

(i) 4,517 shares of Peoples common stock would be exchanged for shares of Summit common stock (determined by multiplying (x) the number of stock election shares (5,000) by (y) a fraction, the numerator of which is the maximum stock consideration and the denominator of which is the stock election number (271,021 /300,000, or 0.903403); and

(ii) 483 shares of Peoples common stock would be exchanged for cash.

Cash Consideration Proration.

If the stock election number is less than the maximum stock consideration (the amount by which the maximum stock consideration exceeds the stock election number is referred to as the shortfall number), then all stock election shares shall be converted into the right to receive the stock consideration, and the no election shares and cash election shares shall be treated as described below.

If the shortfall number is less than or equal to the number of no election shares, then all cash election shares shall be converted into the right to receive the cash consideration, and the no election shares of each holder thereof shall convert into the right to receive the stock consideration in respect of that number of no election shares equal to the product obtained by multiplying (1) the number of no election shares held by such holder by (2) a fraction, the numerator of which is the shortfall number and the denominator of which is the total number of no election shares, with the remaining number of such holder’s no election shares being converted into the right to receive the cash consideration.

Or, if the shortfall number exceeds the number of no election shares, then all no election shares shall be converted into the right to receive the stock consideration, and the cash election shares of each holder thereof

60

shall convert into the right to receive the stock consideration in respect of that number of cash election shares equal to the product obtained by multiplying (A) the number of cash election shares held by such holder by (B) a fraction, the numerator of which is the amount by which (x) the shortfall number exceeds (y) the total number of no election shares and the denominator of which is the total number of cash election shares, with the remaining number of such holder’s cash election shares being converted into the right to receive the cash consideration.

By way of example, assuming that all shareholders make an election (and as a result, there are zero no election shares), if there are a total of 241,021 stock election shares, a total of 300,000 cash election shares and the maximum stock consideration equals 271,021, resulting in a shortfall number of 30,000, then the shares of Peoples common stock held by a shareholder with 5,000 cash election shares electing cash would be exchanged in the following manner:

(i) 500 shares of Peoples common stock would be exchanged for shares of Summit common stock (determined by multiplying (x) the number of cash election shares electing cash held by such holder by (y) a fraction, the numerator of which is the shortfall number less the number of no election shares (or zero) and the denominator of which is the total cash election shares (30,000 / 300,000, or 0.10); and

(ii) 4,500 shares of Peoples common stock would be exchanged for cash.

The pro rata selection process to be used by the exchange agent shall consist of such equitable pro ration processes as shall be mutually determined by Summit and Peoples.
