PRELIMINARY — SUBJECT TO COMPLETION — DATED JANUARY 4, 2018

MERGER PROPOSAL — YOUR VOTE IS VERY IMPORTANT

The board of directors of Wesbanco, Inc., or WesBanco, and the board of directors of First Sentry Bancshares, Inc., or First Sentry, have agreed to a merger of the two companies under the terms of the Agreement and Plan of Merger, dated November 13, 2017, and referred to in this document as the merger agreement, by and among WesBanco, Wesbanco Bank, Inc., First Sentry and First Sentry Bank, Inc. At the effective time of the merger, First Sentry will merge with and into WesBanco with WesBanco continuing as the surviving corporation.

If the merger contemplated by the merger agreement is completed, each share of common stock of First Sentry outstanding immediately prior to the effective time of the merger, will be converted into the right to receive 1.5869 shares of common stock of WesBanco. WesBanco shares will be unaffected by the merger and the merger will betax-free to WesBanco shareholders. Shareholders of First Sentry generally will not recognize any gain or loss upon receipt of shares of WesBanco common stock in exchange for First Sentry common stock in the merger, except with respect to cash received in lieu of fractional shares of WesBanco common stock.

This proxy statement/prospectus is being distributed in connection with a special meeting of First Sentry shareholders. At that meeting, First Sentry shareholders will be asked to consider the following matters: (1) a proposal to approve the merger agreement; and (2) a proposal to approve the adjournment of the First Sentry special meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the First Sentry special meeting to approve the proposal to approve the merger agreement.

The number of shares of WesBanco common stock that First Sentry shareholders will receive for the merger consideration is fixed, so that the market value of those shares will fluctuate with the market price of WesBanco common stock and will not be known at the time First Sentry shareholders vote on the merger agreement. Based on the closing price of WesBanco’s common stock of $38.92 on the NASDAQ Global Select Market on November 13, 2017, the last full trading day immediately prior to the public announcement of the merger agreement, the 1.5869 exchange ratio represented approximately $61.76 in value for each share of First Sentry common stock. Based on the $40.58 closing price of WesBanco’s common stock on January 2, 2018, the last practicable full trading day before the date of this proxy statement/prospectus, the 1.5869 exchange ratio represented approximately $64.40 in value for each share of First Sentry common stock. We urge you to obtain current market quotations for WesBanco common stock (NASDAQ: trading symbol “WSBC”). Based on the number of shares of First Sentry common stock (1) outstanding and (2) potentially issuable pursuant to outstanding stock options that are vested or that are expected to vest prior to completion of the merger, the maximum number of shares of WesBanco common stock issuable in the merger is expected to be approximately 2,538,991 shares.

Your vote is very important.Whether or not you plan to attend the First Sentry shareholders’ meeting, please take the time to vote by completing and mailing the enclosed proxy card in accordance with the instructions on the proxy card. First Sentry shareholders may also cast their votes over the Internet or by telephone in accordance with the instructions on the proxy card. We cannot complete the merger unless First Sentry shareholders approve the merger agreement.

The accompanying document is a proxy statement of First Sentry and a prospectus of WesBanco, and provides you with information about First Sentry, WesBanco, the proposed merger and the special meeting of First Sentry shareholders.First Sentry encourages you to carefully and thoughtfully read this entire document, including all its annexes, and we especially encourage you to read the section entitled“Risk Factors”beginning on page 18. You also can obtain information about WesBanco from publicly available documents filed with the Securities and Exchange Commission.

After careful consideration, the First Sentry board of directors unanimously approved the merger agreement, the merger and the other transactions contemplated by the merger agreement and determined that the merger agreement, the merger and the other transactions contemplated by the merger agreement are in the best interests of First Sentry and its shareholders.Accordingly,the First Sentry board of directors unanimously recommends that First Sentry shareholders vote “FOR” the proposal to approve the merger agreement, and “FOR” the proposal to approve the adjournment of the First Sentry special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to approve the merger agreement at the scheduled time of the special meeting.

We thank you for your continued support of First Sentry and look forward to the successful completion of the merger.

Sincerely,

Robert H. Beymer

QUESTIONS AND ANSWERS

The following are some questions that you, as a shareholder of First Sentry, may have regarding the merger and the other matters being considered at the special shareholders’ meeting and the answers to those questions. WesBanco and First Sentry strongly recommend that you carefully read the remainder of this document because the information in this section does not provide all the information that might be important to you with respect to the merger and the other matters being considered at the shareholders’ meeting. Additional important information is also contained in the annexes to, and the documents incorporated by reference into, this document.

Q: Why have I received this proxy statement/prospectus?

A: The boards of directors of WesBanco and First Sentry have each approved a merger agreement, entered into on November 13, 2017, providing for First Sentry to be acquired by WesBanco. A copy of the merger agreement is attached to this proxy statement/prospectus asAnnex A, which we encourage you to review. In order to complete the merger, First Sentry shareholders must vote to approve the merger agreement.

IF FIRST SENTRY SHAREHOLDERS FAIL TO APPROVE THE MERGER AGREEMENT, THE MERGER CANNOT BE COMPLETED.

This document contains important information about the merger and the meeting of First Sentry shareholders and you should read it carefully. The enclosed voting materials allow you to vote your shares without attending the First Sentry special meeting.

Your vote is very important. The First Sentry board of directors encourages you to vote as soon as possible.

Q: What matters are to be voted on at the First Sentry special meeting?

A: At the First Sentry special meeting, holders of First Sentry common stock as of the close of business on December 29, 2017 (the “record date”) will be asked to:

1. Approve the merger agreement; and

2. Approve the adjournment of the First Sentry special meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the First Sentry special meeting to approve the proposal to approve the merger agreement.

Q: What will First Sentry shareholders receive as a result of the merger?

A: First Sentry shareholders will receive 1.5869 shares of WesBanco common stock, sometimes referred to as the exchange ratio or the merger consideration, in exchange for each share of First Sentry common stock. Instead of fractional shares of WesBanco, First Sentry shareholders will receive a check for any fractional shares based on the average closing price of WesBanco common stock during a specified period before the effective time of the merger.

Because the number of shares of WesBanco common stock that First Sentry shareholders will receive is fixed, the implied value of the merger consideration will fluctuate as the market price of WesBanco common stock fluctuates.As a result, the value of the merger consideration that you will receive upon completion of the merger could be greater than, less than or the same as the value of the merger consideration on the date of this proxy statement/prospectus or at the time of the First Sentry special

meeting.You should obtain current stock price quotations for WesBanco common stock and First Sentry common stock before deciding how to vote with respect to the approval of the merger agreement. WesBanco common stock is listed for trading on the Nasdaq Global Select Market under the symbol “WSBC.” First Sentry common stock is listed on the OTCPink market of the OTC Markets Group, Inc. under the symbol “FTSB.”

Q: What does the First Sentry board of directors recommend?

A: The First Sentry board of directors has unanimously determined that the merger is in the best interests of First Sentry and First Sentry’s shareholders and unanimously recommends that you vote:

• FOR the proposal to approve the merger agreement; and

• FOR the proposal to approve of the adjournment of the First Sentry special meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the First Sentry special meeting to approve the proposal to approve the merger agreement.

In making this determination, our board of directors considered the factors described under “Proposal No.1 — Approval of the Merger Agreement — First Sentry’s Reasons for the Merger; Recommendation of the First Sentry Board of Directors.”

Q: When and where will the special meeting of First Sentry shareholders be held?

A: The First Sentry special meeting will be held at The Pullman Plaza Hotel, 1001 Third Avenue, Huntington, West Virginia, on February 9, 2018, at 3:00 pm Eastern Time.

Q: Who can vote at the special meeting?

A: Holders of record of First Sentry common stock at the close of business on December 29, 2017, the record date, will be entitled to notice of and to vote at the First Sentry special meeting. Each of the shares of First Sentry common stock issued and outstanding on the record date is entitled to one vote at the First Sentry special meeting with regard to each of the proposals described above.

Q: When do you expect to complete the merger?

A: We anticipate that we will obtain all necessary regulatory approvals, and be able to consummate the merger in the first half of 2018. However, we cannot assure you when or if the merger will occur. We must first obtain the requisite approval of First Sentry shareholders at the First Sentry special meeting, and WesBanco and First Sentry must obtain the requisite regulatory approvals to complete the merger.

Q: What happens if the merger is not completed?

A: If the merger is not completed, holders of First Sentry common stock will not receive any consideration for their shares in connection with the merger. Instead, First Sentry will remain an independent company. In certain circumstances, First Sentry may be required to pay a termination fee, as discussed more fully under “Proposal No.1 — Approval of the Merger Agreement — Termination Fee.”

Q: What vote of First Sentry shareholders is required to approve each proposal?

A: To be approved, proposal no. 1 (approval of the merger agreement) and proposal no. 2 (adjournment proposal) require that the number of votes cast favoring approval of the proposal exceeds the votes cast opposing the proposal at the First Sentry special meeting.

- 2 -

As of the record date, there were 1,563,169 shares of First Sentry common stock outstanding and entitled to vote at the First Sentry special meeting, held by approximately 805 holders of record. As of the record date, the directors and executive officers of First Sentry had the right to vote approximately 12.20% of the outstanding shares of First Sentry common stock entitled to vote at the special meeting. In addition, the executive officers and directors of First Sentry have entered into voting agreements with WesBanco in which each executive officer or director has agreed to vote all of the shares of First Sentry common stock with respect to which he or she has sole voting power and beneficial ownership in favor of approval of the merger agreement.

Q: How do I vote?

A: If you are a shareholder of record of First Sentry as of the record date, you may vote in person by attending the First Sentry special meeting or, to ensure your shares are represented at the First Sentry special meeting, you may vote by:

• accessing the Internet website specified on your proxy card;

• calling the toll-free number specified on your proxy card; or

• signing and returning the enclosed proxy card in the postage-paid envelope provided.

If you hold your First Sentry shares in the name of a bank or broker, please see the discussion below.

Q: What is a quorum?

A: In order for business to be conducted at the First Sentry special meeting, a quorum must be present. The quorum requirement for holding and transacting business at the First Sentry special meeting is that a majority of the outstanding shares of First Sentry common stock entitled to vote as of the record date be present or represented at the First Sentry special meeting. The shares may be present in person or represented by proxy at the First Sentry special meeting. Proxies received but marked as abstentions are considered to be present and entitled to vote at the meeting for the purposes of determining a quorum.

Q: Your shares are held in your broker’s name (also known as “street name”). How do you vote those shares?

A: Copies of this proxy statement/prospectus were sent to you by your broker. The broker will request instructions from you as to how you want your shares to be voted, and the broker will vote your shares according to your instructions.

Q: If your shares are held in “street name” by a broker, won’t your broker vote those shares for you?

A: Not unless you provide your broker with instructions on how to vote your “street name” shares. Under the rules of the New York Stock Exchange which govern brokers, when the beneficial holder of shares held in street name does not provide voting instructions, brokers, banks and other nominees have the discretion to vote those shares only on certain “routine matters.” None of the proposals to be voted upon at the First Sentry special meeting are routine matters, so brokers, banks and other nominees holding shares in street name will not be permitted to exercise voting discretion on any of those proposals. Therefore, if a beneficial holder of shares of First Sentry common stock does not give the broker, bank or other nominee any voting instructions, the holder’s shares of common stock will not be voted on those proposals. It is important that you be sure to provide your broker with instructions on how to vote your shares held in street name.

- 3 -

Abstentions, if any, and brokernon-votes, if any, are counted as present for the purpose of determining whether a quorum is present. Once a quorum for the First Sentry special meeting is established, abstentions, brokernon-votes, and shares that are not voted will not have any effect on the outcome of either the proposal to approve the merger agreement or the adjournment proposal.

Please check the voting form used by your broker to see if it offers telephone or Internet submission of proxies.

Q: What happens if you return your signed proxy card without indicating how to vote?

A: If you return your signed proxy card without indicating how to vote on any particular proposal, the First Sentry shares represented by your proxy will be voted on each proposal presented at the First Sentry special meeting in accordance with the First Sentry board’s recommendation on that proposal. Therefore, if you return a signed proxy card without indicating how to vote on any particular proposal, your shares of First Sentry common stock will be voted“FOR”approval of the merger agreement; and“FOR” the adjournment of the First Sentry special meeting, if necessary, to solicit additional proxies in favor of the approval of the merger agreement.

Q: Can you change your vote after you have delivered your proxy card?

A: Yes. You may change your vote at any time before your proxy is voted at the First Sentry special meeting. You can do this in any of the three following ways:

• by sending a written notice to the corporate secretary of First Sentry in time to be received before the First Sentry special meeting stating that you would like to revoke your proxy;

• by completing, signing and dating another proxy card bearing a later date and returning it by mail in time to be received before the First Sentry special meeting; or you can change your vote by submitting a new, valid proxy by Internet or telephone, with a later date, in which case your later submitted proxy will be recorded and your earlier proxy revoked; or

• if you are a holder of record, by attending the First Sentry special meeting and voting in person.

If your shares are held in an account at a broker or bank, you should contact your broker or bank to change your vote.

Q: Will First Sentry shareholders have appraisal rights or dissenters’ rights?

A: Yes. Under West Virginia law, holders of First Sentry common stock will be entitled to exercise appraisal or dissenters’ rights in connection with the First Sentry proposal to approve the merger agreement.

SUMMARY

This summary highlights selected information from this proxy statement/prospectus and may not contain all of the information that is important to you. The merger agreement is attached to this proxy statement/prospectus as Annex A. To fully understand the merger and for a more complete description of the terms of the merger, you should carefully read this entire document, including the annexes, and the documents we refer you to under the caption “Where You Can Find More Information” beginning on page 84. This proxy statement/prospectus, including information included or incorporated by reference in this proxy statement/prospectus, contains a number of forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 regarding the financial condition, results of operations, earnings outlook, business and prospects of WesBanco and First Sentry, and the potential combined company, as well as statements applicable to the period following the completion of the merger. You can find some of these statements by looking for words such as “plan,” “believe,” “expect,” “intend,” “anticipate,” “estimate,” “project,” “potential,” “possible” or other similar expressions. These forward-looking statements involve certain risks and uncertainties. The ability of either WesBanco or First Sentry to predict results or the actual effects of their plans and strategies, particularly after the merger, is inherently uncertain. Because these forward-looking statements are subject to assumptions and uncertainties, actual results may differ materially from those expressed in or implied by these forward-looking statements. See “Cautionary Statement Regarding Forward-Looking Statements” on page 85.

Unless the context otherwise requires, throughout this proxy statement/prospectus, “we,” “us,” “our” or “First Sentry” refers to First Sentry Bancshares, Inc., “WesBanco” refers to Wesbanco, Inc., and “you” refers to the holders of shares of common stock of First Sentry. We refer to the merger between First Sentry and WesBanco as the “merger,” and the Agreement and Plan of Merger dated as of November 13, 2017 between WesBanco, Wesbanco Bank, Inc. First Sentry and First Sentry Bank, Inc. as the “merger agreement.” Also, we refer to the proposed merger of First Sentry Bank, Inc. into Wesbanco Bank, Inc. as the “bank merger.”

The Merger (See page 27)

We propose a merger of First Sentry with and into WesBanco. If the merger is consummated, WesBanco will continue as the surviving corporation. The articles of incorporation and bylaws of WesBanco will continue as the articles of incorporation and bylaws of the surviving corporation until amended or repealed in accordance with applicable law. The officers and directors of WesBanco will continue as the officers and directors of the surviving corporation. After the effective time of the merger and as part of the same overall transaction, First Sentry Bank, Inc., the wholly-owned subsidiary of First Sentry, for no additional consideration and pursuant to the merger agreement, will merge with and into Wesbanco Bank, Inc., the wholly-owned subsidiary of WesBanco.

First Sentry is a bank holding company headquartered in Huntington, West Virginia. First Sentry is the holding company for First Sentry Bank, Inc., a West Virginia banking corporation.

What First Sentry Shareholders Will Receive in the Merger (See page 27)

If the merger is completed, for each share of First Sentry common stock that you own you will receive 1.5869 shares of WesBanco common stock, subject to possible adjustment in accordance with the terms of the merger agreement as discussed below. We refer to the 1.5869 shares of WesBanco common stock as the “merger consideration” or the “exchange ratio.” Instead of fractional shares of WesBanco, First Sentry shareholders will receive a check for any fractional shares based on the average closing price of WesBanco common stock during a specified period before the effective time of the merger.

The exchange ratio is a fixed ratio. Therefore, the number of shares of WesBanco common stock to be received by holders of First Sentry common stock in the merger will not change if the trading price of WesBanco common stock or the market value of First Sentry common stock changes between now and the time the merger is completed, except in limited circumstances where the trading price of WesBanco common stock falls below certain thresholds when measured during a period shortly before the date that the merger is scheduled to be completed, in which case, First Sentry will have an opportunity to terminate the merger agreement if WesBanco elects not to adjust the exchange rate accordingly.

The exchange ratio is subject to adjustment if WesBanco completes certain corporate transactions, such as a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other like changes in WesBanco’s capitalization.

First Sentry’s Reasons for the Merger and Recommendation to Shareholders(See page 33)

The First Sentry board of directors has unanimously determined that the merger agreement and the merger are in the best interests of First Sentry and its shareholders,and accordingly unanimously approved the merger agreement and recommends that First Sentry shareholders vote “FOR” the approval of the merger agreement.

In determining whether to approve the merger agreement and recommend approval of the merger agreement to the First Sentry shareholders, First Sentry’s board considered the factors described under “Proposal No. 1 —Approval of the Merger Agreement — First Sentry’s Reasons for the Merger; Recommendation of the First Sentry Board of Directors.”

In addition, the First Sentry board of directors unanimously recommends that First Sentry shareholders vote“FOR”the proposal to approve of the adjournment of the First Sentry special meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the First Sentry special meeting to approve the proposal to approve the merger agreement.

Opinion of First Sentry’s Financial Advisor (See page 36)

In connection with the merger, First Sentry’s financial advisor, Sandler O’Neill & Partners, L.P. (“Sandler O’Neill”), delivered to the First Sentry board of directors a written opinion dated November 11, 2017 to the effect that, as of such date and based upon and subject to the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by Sandler O’Neill as set forth in its opinion, the exchange ratio set forth in the merger agreement was fair to the holders of shares of First Sentry common stock, from a financial point of view.

The full text of Sandler O’Neill’s opinion, which describes the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by Sandler O’Neill in preparing the opinion, is attached asAnnex B to this proxy statement/prospectus.First Sentry shareholders are urged to read the entire opinion carefully in connection with their consideration of the proposed merger. Sandler O’Neill’s opinion speaks only as of the date of the opinion.The opinion was for the information of, and was directed to, the First Sentry board (in its capacity as such) in connection with its consideration of the financial terms of the merger. The opinion did not address the underlying business decision of First Sentry to engage in the merger or enter into the merger agreement, nor does it constitute a recommendation to the First Sentry board in connection with the merger or a recommendation to any holder of First Sentry common stock or any shareholder of any other entity as to how to vote in connection with the merger or any other matter. Sandler O’Neill did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the merger by First Sentry’s officers, directors, or employees, or class of such persons, relative to the compensation to be received in the merger by any other shareholders of First Sentry.

Treatment of First Sentry Stock Options(See page 30)

The merger agreement provides that upon completion of the merger, each option to purchase shares of First Sentry common stock then outstanding, whether or not then exercisable, will be cancelled in exchange for the right to receive an amount in cash, without interest, equal to the product of (i) the aggregate number of shares of First Sentry common stock subject to such stock option, multiplied by (ii) the excess, if any, of $64.00 over the per share exercise price of such First Sentry stock option. The cash payment will be subject to applicable tax withholding. First Sentry has agreed to take the actions necessary to implement the provisions of the merger agreement relating to the cancellation of outstanding options to purchase shares of First Sentry common stock in the merger in exchange for cash.

Special Meeting(See page 24)

A special meeting of First Sentry’s shareholders will be held at The Pullman Plaza Hotel, 1001 Third Avenue, Huntington, West Virginia, on Friday, February 9, 2018, at 3:00 pm Eastern Time At the First Sentry special meeting, First Sentry shareholders will be asked to: (i) approve the merger agreement; and (ii) approve an adjournment of the First Sentry special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to approve the merger agreement at the time of the First Sentry special meeting.

Vote Required(See page 24)

Merger Agreement Proposal.If a quorum exists, 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. Abstentions, brokernon-votes, and unvoted shares will have no effect on the outcome of the proposal to approve the merger agreement.

Adjournment Proposal.If a quorum exists, approval of the adjournment of the First Sentry special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to approve the merger agreement at the time of the First Sentry special meeting, requires that the number of votes cast favoring the adjournment proposal exceeds the number of votes cast opposing the adjournment proposal. Abstentions, brokernon-votes, and unvoted shares will have no effect on the outcome of the adjournment proposal.

Voting Agreements (See page 70)

In connection with the merger agreement, WesBanco entered into voting agreements with all of First Sentry’s directors and executive officers, who are Robert H. Beymer, Kerry P. Dillard, David Fox, III, Jeffrey E. Hood, Johnnie Jones, Nester S. Logan, Joseph K. McDonie, J. Grant McGuire, Charles H. McKown, Jr., MD, Edward W. Morrison, Jr., Sally C. B. Oxley, George A. Patterson, III, Geoffrey S. Sheils, P. Todd Shell, J. Roger Smith, Paul L. Turman, II, John Jay White, Joseph Williams, S. Kenneth Wolfe, MD, Kelly M. Young, Toby Taylor and Richard D. Hardy. In the voting agreements, each of these shareholders has generally agreed to vote all of the shares of First Sentry common stock with respect to which he or she has sole voting power and beneficial ownership to approve the merger agreement.

As of the record date, 190,681 shares of First Sentry common stock, or approximately 12.20% of the outstanding shares of First Sentry common stock entitled to vote at the First Sentry special meeting, were subject to voting agreements.

Quorum; Abstentions and BrokerNon-Votes (See page 24)

A quorum must be present to transact business at the First Sentry special meeting. If you submit a properly executed proxy card, even if you abstain from voting, your shares will be counted for purposes of calculating whether a quorum is present at the special meeting. A quorum at the First Sentry special meeting requires the presence, whether in person or by proxy, of a majority of the outstanding shares of First Sentry common stock entitled to vote as of the record date.

An abstention occurs when a shareholder attends a meeting, either in person or by proxy, but abstains from voting. A brokernon-vote occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power for that particular item and has not received instructions from the beneficial owner. Neither of the proposals to be voted upon at the First Sentry special meeting are routine matters, and brokers, banks and other nominees holding shares in street name will not be permitted to vote on any proposal without instructions from the beneficial holder with respect to that specific proposal. If a beneficial holder of shares of First Sentry common stock does not give the broker, bank or other nominee any voting instructions, the holder’s shares of common stock will not be voted on any proposal.

At the First Sentry special meeting, abstentions and brokernon-votes will be counted in determining whether a quorum is present. However, abstentions, brokernon-votes, and unvoted shares will have no effect on the outcome of either the merger agreement proposal or the adjournment proposal. If no instruction as to how to vote is given (including no instruction to abstain) in an executed, duly returned and not revoked proxy, the proxy will be voted“FOR” (i) the proposal to approve the merger agreement and (ii) the proposal to approve of the

- 9 -

adjournment of the First Sentry special meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the First Sentry special meeting to approve the proposal to approve the merger agreement.

Dissenters’ or Appraisal Rights (See page 53)

If the merger is consummated, holders of record of First Sentry common stock who follow the procedures specified by Sections31D-13-1301 through31D-13-1331 of the West Virginia Business Corporation Act 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. First Sentry shareholders who elect to follow these procedures are referred to as dissenting shareholders.You must notvote in favor of the merger agreement to be eligible to exercise appraisal or dissenters’ rights.

Shares to be Issued by WesBanco in the Merger; Ownership of WesBanco after the Merger(See page 55)

WesBanco will issue a maximum of approximately 2,538,991 shares of its common stock to First Sentry shareholders in connection with the merger, based on the number of (1) shares of First Sentry common stock outstanding on the record date and (2) shares of First Sentry common stock potentially issuable pursuant to outstanding stock options, assuming no adjustment to the exchange ratio is made. Assuming that WesBanco issues that maximum number of shares, those shares would constitute approximately 5.5% of the outstanding stock of WesBanco after the merger, based on the number of shares of WesBanco common stock outstanding on the record date. The WesBanco shares to be issued in the merger will be listed for trading on the Nasdaq Global Select Market under the symbol “WSBC.”

Material U.S. Federal Income Tax Consequences(See page 55)

It is a condition to the completion of the merger, unless waived by the parties in writing, that each of WesBanco and First Sentry receives a legal opinion from their respective tax counsel to the effect that the merger will be treated as a “reorganization” for U.S. federal income tax purposes within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). Accordingly, holders of First Sentry common stock are not expected to recognize any gain or loss for U.S. federal income tax purposes on the exchange of First Sentry common stock for shares of WesBanco common stock in the merger, except with respect to any cash received instead of fractional shares of WesBanco common stock. For further information, please refer to “Proposal No. 1 — Approval of the Merger Agreement — Material U.S. Federal Income Tax Consequences of the Merger” beginning on page     .

You should read the summary under the caption “Proposal No. 1 — Approval of the Merger Agreement — Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 55 for a more complete discussion of the U.S. federal income tax consequences of the merger. You should also consult your own tax advisor concerning all U.S. federal, state, local and foreign tax consequences of the merger that may apply to you.

Certain Differences in the Rights of Shareholders(See page 76)

First Sentry and WesBanco are both West Virginia corporations governed by West Virginia law. Once the merger occurs, First Sentry shareholders will become shareholders of WesBanco and, while their rights will continue to be governed by West Virginia law, they will also be governed by WesBanco’s corporate governing documents rather than First Sentry’s governing documents. Because of the differences between the respective corporate governing documents of First Sentry and WesBanco, First Sentry’s shareholders’ rights as shareholders will change as a result of the merger. This proxy statement/prospectus contains descriptions of the material differences in shareholder rights under each of the WesBanco and First Sentry governing documents.

Conditions to the Merger (See page 64)

Completion of the merger is subject to the satisfaction or waiver of the conditions specified in the merger agreement, including, among others, those listed below:

• the absence of a law or injunction prohibiting the merger;

• receipt by WesBanco and First Sentry of all necessary approvals of governmental and regulatory authorities;

• the receipt of an opinion from each party’s tax counsel, dated as of the closing date of the merger, to the effect that for federal income tax purposes the merger will be treated as a reorganization within the meaning of Section 368(a) of the Code;

Termination of the Merger Agreement(See page 65)

The parties can agree to terminate the merger agreement at any time prior to completion of the merger, and either WesBanco or First Sentry can terminate the merger agreement if, among other reasons, any of the following occurs:

• the merger agreement is not approved by the First Sentry shareholders;

• the merger is not completed by September 30, 2018;

• a court or other governmental authority permanently prohibits the merger; or

• the other party breaches or materially fails to comply with any of its representations, warranties or obligations under the merger agreement.

First Sentry will also have the right to terminate the merger agreement if the average closing price of WesBanco common stock during a specified period before the effective time of the merger is less than $31.10 and WesBanco common stock underperforms the Nasdaq Bank Index by more than 20%, unless WesBanco were to elect to make a compensating adjustment to the exchange ratio. Subject to certain conditions, First Sentry may also terminate the merger agreement in order to enter into an agreement with respect to an unsolicited proposal that if consummated would be reasonably likely to result in a transaction more favorable to First Sentry’s shareholders from a financial point of view, provided that First Sentry pays the termination fee described below upon entering into such an agreement.

Termination Fee(See page 67)

The merger agreement provides that if the merger agreement is terminated under certain circumstances, described more fully beginning on page 67, First Sentry will be required to pay a termination fee of $3,000,000 to WesBanco.

- 11 -

We May Amend the Terms of the Merger and Waive Rights Under the Merger Agreement(See page 69)

We may jointly amend the terms of the merger agreement, and either party may waive its right to require the other party to adhere to any of those terms, to the extent legally permissible. However, after the approval of the merger agreement by the First Sentry shareholders, there may not be, without further approval of First Sentry’s shareholders, any amendment of the merger agreement that requires such further approval under applicable law or would alter the amount or kind of the merger consideration to be received by First Sentry shareholders.

Effective Date of the Merger(See page 69)

We expect the merger to be completed as soon as practicable after all regulatory approvals and shareholder approvals have been received. We expect this to occur during the first half of 2018.

Regulatory Approvals(See page 52)

In addition to the approval of the First Sentry shareholders, the merger is subject to the approval of the Federal Deposit Insurance Corporation, Board of Governors of the Federal Reserve System (unless a waiver is granted, which occurred on December 20, 2017), and the West Virginia Division of Financial Institutions. These governmental authorities may impose conditions for granting approval of the merger. Neither WesBanco nor First Sentry can offer any assurance that all necessary approvals will be obtained or the date when any such approvals will be obtained. As of the date of this proxy statement/prospectus, we have not yet received the required regulatory approvals.

Interests of Certain Persons in the Merger(See page 49)

The directors and executive officers of First Sentry have financial and other interests in the merger that differ from, or are in addition to, their interests as shareholders of First Sentry. These interests include, but are not limited to:

• the continued indemnification of current and former directors and executive officers under the merger agreement and providing these individuals with directors’ and officers’ insurance for four years after the merger;

• the receipt of payments by the executive officers of First Sentry pursuant to employment or change in control severance agreements with First Sentry;

Sheils and Toby Taylor and a settlement agreement with Richard Hardy, pursuant to which each will receive certain payments upon completion of the merger;

• the creation of a retention bonus pool for the purpose of retaining the services of certain key employees of First Sentry; and

• grants of WesBanco restricted stock to certain key employees of First Sentry, effective upon completion of the merger, which would cliff vest after three years, for the purpose of retaining those key employees of First Sentry as WesBanco employees after the merger.

- 12 -

The First Sentry board of directors knew about these additional interests, and considered them when the board approved and approved the merger agreement. See “Proposal No. 1 — Approval of the Merger Agreement — Interests of Certain Persons in the Merger” beginning on page 49 for more detailed information about these interests.

Adjournment Proposal(See page 83)

First Sentry shareholders are being asked to approve a proposal to grant First Sentry’s board of directors discretionary authority to adjourn the First Sentry special meeting, if necessary, to solicit additional proxies in favor of the merger proposal if a quorum is present at the First Sentry special meeting but there are insufficient votes to approve the merger agreement.

Recommendation of the First Sentry Board of Directors(See pages 26 and 83)

The First Sentry board of directors determined that the merger is in the best interests of First Sentry shareholders. Accordingly, it has unanimously recommended that First Sentry shareholders vote“FOR” the proposal to approve the merger agreement.

In addition the First Sentry board of directors unanimously recommends that First Sentry shareholders vote“FOR”the proposal to adjourn the First Sentry special meeting, if necessary, to solicit additional proxies in favor of the approval of the merger agreement.

Holders of WesBanco common stock are entitled to receive dividends when, as and if declared by WesBanco’s board of directors out of funds legally available for dividends. Historically, WesBanco has paid quarterly cash dividends on its common stock, and its board of directors presently intends to continue to pay regular quarterly cash dividends. WesBanco’s ability to pay dividends to its shareholders in the future will depend on its earnings and financial condition, liquidity and capital requirements, the general economic and

- 14 -

regulatory climate, its ability to service any equity or debt obligations senior to its common stock, including its outstanding trust preferred securities and accompanying junior subordinated debentures, and other factors deemed relevant by its board of directors. In order to pay dividends to shareholders, WesBanco must receive cash dividends from WesBanco Bank. As a result, WesBanco’s ability to pay future dividends will depend upon the earnings of WesBanco Bank, its financial condition and its need for funds. A discussion of the restrictions on WesBanco’s dividend payments is included in WesBanco’s Annual Report on Form10-K for the fiscal year ended December 31, 2016. See “Where You Can Find More Information.”

As of December 31, 2017, the last date prior to distribution of this proxy statement/prospectus for which it was practicable to obtain this information, there were approximately 6,669 registered holders of WesBanco common stock and approximately 805 registered holders of First Sentry common stock.

RISK FACTORS

In addition to the other information contained in or incorporated by reference into this proxy statement/prospectus, including the matters addressed under the caption “Cautionary Statement Regarding Forward-Looking Statements” beginning on page85, you should consider the following risk factors carefully in deciding whether to vote to approve the merger agreement. Additional risks and uncertainties not presently known to WesBanco or First Sentry that are not currently believed to be important to you, if they materialize, also may adversely affect the merger and WesBanco as the surviving corporation in the merger.

In addition, WesBanco’s and First Sentry’s respective businesses are subject to numerous risks and uncertainties, including the risks and uncertainties described, in the case of WesBanco, in its Annual Report on Form10-K for the year ended December 31, 2016 and subsequent Quarterly Reports on Form10-Q, each of which are incorporated by reference into this proxy statement/prospectus. See the section entitled “Where You Can Find More Information” beginning on page84 of this proxy statement/prospectus.

Because the market price of WesBanco common stock may fluctuate, First Sentry shareholders cannot be certain of the market value of the WesBanco common stock that they will receive in the merger.

Upon completion of the merger, each share of First Sentry common stock will become the right to receive 1.5869 shares of WesBanco common stock. Any change in the price of WesBanco common stock prior to completion of the merger will affect the market value of the stock that First Sentry shareholders will receive on the date of the merger. First Sentry will not have the right to terminate the merger agreement due to a decline in the trading price of WesBanco common stock unless both (a) the average closing price of WesBanco common stock during a specified period before the effective time of the merger is less than $31.10 and (b) WesBanco common stock underperforms the Nasdaq Bank Index by more than 20% and WesBanco declines to make a compensating adjustment to the exchange ratio.

Stock price changes may result from a variety of factors, including general market and economic conditions, changes in WesBanco’s businesses, operations and prospects, and regulatory considerations. We urge First Sentry shareholders to obtain current market quotations for WesBanco and First Sentry common stock when deciding how to vote.

If the price of WesBanco common stock declines, First Sentry shareholders may receive less value for their shares upon completion of the merger than the value calculated pursuant to the exchange ratio on the date the merger agreement was executed, on the date of this proxy statement/prospectus or on the date of the First Sentry shareholder meeting. For example, based on the range of closing prices of WesBanco common stock during the period from November 13, 2017, the last full trading day before public announcement of the merger, through January 2, 2018, the last practicable full trading day prior to the date of this proxy statement/prospectus, the exchange ratio represented a value ranging from a high of $67.35 on December 4, 2017 to a low of $61.76 on November 13, 2017 for each share of First Sentry common stock. Because the date the merger is completed will be later than the date of the First Sentry special meeting, First Sentry shareholders will not know what the market value of WesBanco common stock will be upon completion of the merger when voting at the First Sentry special meeting.

The opinion of First Sentry’s financial advisor delivered to the First Sentry board of directors does not reflect changes in circumstances after the date of the opinion.

The First Sentry board of directors received an opinion, dated November 11, 2017, from First Sentry’s financial advisor as to the fairness of the merger consideration to First Sentry shareholders from a financial point of view as of that date. Subsequent changes in the operation and prospects of First Sentry or WesBanco, general market and economic conditions and other factors that may be beyond the control of First Sentry or WesBanco may significantly alter the value of First Sentry or WesBanco or the prices of the shares of First Sentry common stock or WesBanco common stock by the time the merger is completed. The opinion does not speak as of the

- 18 -

time the merger is completed, or as of any other date other than the date of the opinion. The opinion of First Sentry’s financial advisor is attached as Annex B to this proxy statement/prospectus. See “Proposal No. 1 — Approval of the Merger Agreement — Opinion of First Sentry’s Financial Advisor” beginning on page 36 for a description of the opinion and a summary of the analyses performed by First Sentry’s financial advisor in connection with its opinion.

The combined company will incur significant transaction and merger-related costs in connection with the merger.

WesBanco and First Sentry expect to incur costs associated with combining the operations of the two companies. WesBanco and First Sentry have just recently begun collecting information in order to formulate detailed integration plans to deliver planned synergies. Additional unanticipated costs may be incurred in the integration of the businesses of WesBanco and First Sentry. Whether or not the merger is consummated, WesBanco and First Sentry will incur substantial expenses, such as legal, accounting, printing and financial advisory fees, in pursuing the merger. Although WesBanco and First Sentry expect that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses may offset incremental transaction and merger-related costs over time, this net benefit may not be achieved in the near term, or at all.

If the merger is not completed, WesBanco and First Sentry will have incurred substantial expenses without their shareholders realizing the expected benefits of the merger.

WesBanco and First Sentry have each incurred substantial expenses in connection with the transactions described in this proxy statement/prospectus, which are charged to earnings as incurred. If the merger is not completed, these expenses will still be charged to earnings even though WesBanco and First Sentry would not have realized the expected benefits of the merger. There can be no assurance that the merger will be completed.

WesBanco may not be able to successfully integrate First Sentry or to realize the anticipated benefits of the merger.

The merger involves the combination of two companies that previously have operated independently. A successful combination of the operations of the two entities will depend substantially on WesBanco’s ability to consolidate operations, systems and procedures and to eliminate redundancies and reduce costs of the combined operations. WesBanco may not be able to combine the operations of First Sentry and WesBanco without encountering difficulties, such as:

• the loss of key employees and customers;

• the disruption of operations and business;

• the inability to maintain and increase competitive presence;

• deposit attrition, customer loss and revenue loss;

• possible inconsistencies in standards, control procedures and policies;

• unexpected problems with costs, operations, personnel, technology and credit; and/or

• problems with the assimilation of new operations, sites or personnel, which could divert resources from regular banking operations.

Additionally, general market and economic conditions or governmental actions affecting the financial industry generally may inhibit the successful integration of First Sentry and WesBanco.

Further, WesBanco and First Sentry entered into the merger agreement with the expectation that the merger will result in various benefits including, among other things, benefits relating to enhanced revenues, a

- 19 -

strengthened market position for the combined company, cross selling opportunities, technology, cost savings and operating efficiencies. Achieving the anticipated benefits of the merger is subject to a number of uncertainties, including whether WesBanco integrates First Sentry in an efficient and effective manner, and general competitive factors in the marketplace. Failure to achieve these anticipated benefits could result in increased costs, decreases in the amount of expected revenues and diversion of management’s time and energy and could materially impact WesBanco’s business, financial condition and operating results. Finally, any cost savings that are realized may be offset by losses in revenues or other charges to earnings.

The merger agreement may be terminated in accordance with its terms, and the merger may not be completed.

The merger agreement is subject to a number of conditions which must be fulfilled in order to complete the merger. Those conditions include, among others: approval of the merger agreement by First Sentry shareholders, regulatory approvals, absence of orders prohibiting the completion of the merger, effectiveness of the registration statement of which this proxy statement/prospectus is a part, approval of the shares of WesBanco common stock to be issued to First Sentry shareholders for listing on the Nasdaq Global Select Market, the aggregate amount of certain First Sentry loans being below a maximum amount agreed upon by WesBanco and First Sentry, the continued accuracy of the representations and warranties by both parties, the performance by both parties of their covenants and agreements, and the receipt by both parties of legal opinions from their respective tax counsels. See “Proposal No. 1 — Approval of the Merger Agreement — Termination of the Merger Agreement” beginning on page 65 for a more complete discussion of the circumstances under which the merger agreement could be terminated. Any of these conditions to closing of the merger may not be fulfilled, and as a result the merger may not be completed.

Termination of the merger agreement could negatively affect First Sentry.

If the merger agreement is terminated, there may be various consequences, including:

• that First Sentry’s businesses may have been adversely impacted 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; and

• the market price of First Sentry common stock might decline to the extent that the current market price reflects a market assumption that the merger will be completed.

If the merger agreement is terminated and First Sentry’s board of directors seeks another merger or business combination, First Sentry shareholders cannot be certain that First Sentry will be able to find a party willing to offer equivalent or more attractive consideration than the consideration WesBanco has agreed to provide in the merger.

If the merger agreement is terminated, First Sentry may be required to pay abreak-up fee of $3,000,000 to WesBanco under certain circumstances. See “Proposal No. 1 — Approval of the Merger Agreement — Termination Fee” beginning on page 67.

The merger agreement limits First Sentry’s ability to pursue alternatives to the merger.

The merger agreement contains provisions that, subject to very narrow exceptions, limit First Sentry’s ability to discuss, facilitate or enter into agreements with third parties to acquire it. If First Sentry avails itself of those limited exceptions, it could be obligated to pay WesBanco abreak-up fee of $3,000,000 under certain specified circumstances. These provisions could discourage a potential competing acquiror that might have an interest in acquiring First Sentry from proposing or considering such an acquisition even if that potential acquiror were prepared to pay a higher price to shareholders than the merger consideration.

- 20 -

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

Uncertainties about the effect of the merger on employees and customers may have an adverse effect on First Sentry and consequently on WesBanco. These uncertainties may impair First Sentry’s ability to attract, retain and motivate key personnel until the merger is completed, and could cause customers and others that deal with First Sentry to seek to change existing business relationships with First Sentry. Retention of certain employees may be challenging during the pendency of the merger, as certain employees may experience uncertainty about their future roles. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the business, First Sentry’s business prior to the merger and the combined company’s business following the merger could be negatively impacted. In addition, the merger agreement restricts First Sentry from making certain acquisitions and taking other specified actions before the merger occurs without the consent of WesBanco. These restrictions may prevent First Sentry from pursuing business opportunities that may arise prior to the completion of the merger. The merger agreement also allows WesBanco to refuse to close the merger if the aggregate amount of certain identified First Sentry loans is not less than the amount agreed upon by WesBanco and First Sentry in the merger agreement. See “Proposal No. 1 — Approval of the Merger Agreement — Conduct of Business Prior to the Merger” beginning on page 60 for a description of restrictive covenants applicable to First Sentry.

The need for regulatory approvals may delay the date of completion of the merger or may diminish the benefits of the merger.

WesBanco is required to obtain the approvals of certain bank regulatory agencies prior to completing the merger. Satisfying any requirements of these regulatory agencies may delay the date of completion of the merger. The requisite regulatory approvals may not be received at all (in which case the merger could not be completed), may not be received in a timely fashion, or may contain conditions or restrictions on completion of the merger that cannot be satisfied. In addition, you should be aware that, as in any transaction, it is possible that, among other things, restrictions on the combined operations of the two companies, including divestitures, may be sought by governmental agencies as a condition to obtaining the required regulatory approvals. This may diminish the benefits of the merger to the combined company or have an adverse effect on the combined company following the merger. See “Proposal No. 1 — Approval of the Merger Agreement — Regulatory Approvals” on page 52.

First Sentry shareholders will have less influence as shareholders of WesBanco than they have as shareholders of First Sentry.

First Sentry shareholders currently have the right to vote in the election of the board of directors of First Sentry and on other matters affecting First Sentry. Based upon the number of shares of First Sentry common stock outstanding as of the record date, the current shareholders of First Sentry as a group will own approximately 5.3% of the voting power of the combined organization immediately after the merger. When the merger occurs, each First Sentry shareholder will become a shareholder of WesBanco with a percentage ownership of the combined organization much smaller than the shareholder’s current percentage ownership of First Sentry. Because of this, First Sentry shareholders will have less influence on the management and policies of WesBanco than they now have on the management and policies of First Sentry.

Directors and officers of First Sentry have interests in the merger that differ from the interests ofnon-management First Sentry shareholders.

The executive officers of First Sentry and WesBanco, with the assistance of their respective legal counsel and financial advisors, negotiated the terms of the merger agreement. The First Sentry and WesBanco boards of directors have approved the merger agreement, and the First Sentry board of directors is recommending that First Sentry shareholders vote to approve the merger agreement. In considering these facts and the other information included in this proxy statement/prospectus or incorporated by reference into it, you should be aware that First

- 21 -

Sentry’s directors and executive officers have economic interests in the merger beyond their interests as shareholders. These include, for example:

• All of First Sentry’s current directors will be appointed to a newly-created advisory board for WesBanco Bank for the Huntington, West Virginia market.

• WesBanco and First Sentry entered into employment agreement amendments with each of Geoffrey S. Sheils and Toby Taylor and a settlement agreement with Richard D. Hardy, pursuant to which each will receive certain payments upon completion of the merger.

• The merger agreement provides that all outstanding stock options, whether vested or unvested, will be cashed out upon completion of the merger at the difference between the option exercise prices and $64.00.

• WesBanco has created a retention bonus pool for certain key employees to ensure continuity through the conversion of the data processing system of First Sentry and made conditional retention grants of WesBanco restricted stock, which will have a three-year cliff-vesting term, to certain key employees.

• The merger agreement provides that WesBanco will continue the indemnification rights of First Sentry’s current and former directors and executive officers and will provide, for four years after completion of the merger, directors’ and officers’ insurance for these individuals.

See “Proposal No. 1 — Approval of the Merger Agreement — Interests of Certain Persons in the Merger” beginning on page 49.

Following the merger, a high percentage of the combined company’s loan portfolio will be concentrated in West Virginia, Ohio, Pennsylvania, Indiana and Kentucky and in commercial and residential real estate. Deteriorations in economic conditions in these areas or in the real estate market generally could be more harmful to the combined company compared to more diversified institutions.

As of September 30, 2017, approximately 21.3%, of WesBanco’s loan portfolio was comprised of residential real estate loans, and 47.3% was comprised of commercial real estate loans. Assuming the merger had been completed on September 30, 2017, the combined company’s loan portfolio as of that date would have been 21.0% residential real estate loans and 48.0% commercial real estate loans.

Inherent risks of commercial real estate (“CRE”) lending include the cyclical nature of the real estate market, construction risk and interest rate risk. The cyclical nature of real estate markets can cause CRE loans to suffer considerable distress. During these times of distress, a property’s performance can be negatively affected by tenants’ deteriorating credit strength and lease expirations in times of softening demand caused by economic deterioration or over-supply conditions. Even if borrowers are able to meet their payment obligations, they may find it difficult to refinance their full loan amounts at maturity due to declines in property value. Other risks associated with CRE lending include regulatory changes and environmental liability. Regulatory changes in tax legislation, zoning or similar external conditions including environmental liability may affect property values and the economic feasibility of existing and proposed real estate projects.

The combined company’s CRE loan portfolio will be concentrated in West Virginia, Ohio, Pennsylvania, Indiana and Kentucky. There are a wide variety of economic conditions within the local markets of the five states in which most of the combined company’s CRE loan portfolio will be situated. Rates of employment, consumer loan demand, household formation, and the level of economic activity can vary widely from state to state and among metropolitan areas, cities and towns. Metropolitan markets comprise various submarkets where property values and demand can be affected by many factors, such as demographic makeup, geographic features, transportation, recreation, local government, school systems, utility infrastructure, tax burden, building-stock age, zoning and building codes, and available land for development. Despite the merger, as a result of the continued high concentration of the combined company’s loan portfolio, the combined company may be more sensitive,

- 22 -

compared to more diversified institutions, to future disruptions in, and deterioration of, this market, which could lead to losses that could have a material adverse effect on the business, financial condition and results of operations of the combined company.

The merger will likely result in WesBanco being subject to additional regulation and increased supervision.

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 imposes additional regulatory requirements on institutions with $10 billion or more in assets. At September 30, 2017, WesBanco had total consolidated assets of approximately $9.9 billion and First Sentry had total consolidated assets of approximately $666 million. On a pro forma basis assuming completion of the merger, WesBanco would have had approximately $10.6 billion in assets as of September 30, 2017.

When WesBanco surpasses $10 billion in total consolidated assets, upon completion of the merger, WesBanco would be subject to the following:

• Supervision, examination and enforcement by the Consumer Financial Protection Bureau with respect to consumer financial protection laws;

• Regulatory stress testing requirements, whereby WesBanco would be required to conduct an annual stress test (using assumptions for baseline, adverse and severely adverse scenarios);

• A modified methodology for calculating FDIC insurance assessments and potentially higher assessment rates as a result of institutions with $10 billion or more in assets being required to bear a greater portion of the cost of raising the reserve ratio;

• Heightened compliance standards under the Volcker Rule;

• Reduced debit card interchange revenue from applicability of the Durbin Amendment (in general, the Durbin Amendment limits the interchange fees paid to banks by merchants for the privilege of accepting payment cards); and

• Enhanced supervision as a larger financial institution.

The imposition of these regulatory requirements and increased supervision may require additional commitment of financial resources to regulatory compliance and may increase WesBanco’s cost of operations. Further, the results of the stress testing process may lead WesBanco to retain additional capital or alter the mix of its capital components. It is difficult to predict the overall compliance cost of these provisions once WesBanco surpasses $10 billion in total consolidated assets, which WesBanco expects to do as a result of the merger. However, compliance with these provisions will likely require additional staffing, engagement of external consultants and other operating costs as well as result in reduced revenues, all of which could have a material adverse effect on WesBanco’s future financial condition and results of operations.

If the merger does not constitute a reorganization under Section 368(a) of the Code, then each First Sentry shareholder may be responsible for payment of U.S. income taxes related to the exchange of First Sentry common stock for WesBanco common stock.

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

First Sentry is mailing this proxy statement/prospectus to you on or about [●]. Together with this proxy statement/prospectus, First Sentry is also sending to its shareholders a notice of the First Sentry special meeting and a form of proxy that First Sentry’s board of directors is soliciting for use at the First Sentry special meeting and at any adjournments of the meeting.

A copy of the merger agreement is attached to this proxy statement/prospectus asAnnex A and is incorporated by reference into this document in its entirety. You should read the entire merger agreement carefully.

Date, Time and Place of the Special Meeting

The First Sentry special meeting will be held at The Pullman Plaza Hotel, 1001 Third Avenue, Huntington, West Virginia, on Friday, February 9, 2018, at 3:00 pm Eastern Time.

Record Date; Stock Entitled to Vote; Quorum

Only holders of record of First Sentry common stock on December 29, 2017, which we refer to as the record date, will be entitled to notice of and to vote at the First Sentry special meeting and any adjournments of that meeting. On the record date, there were 1,563,169 shares of First Sentry common stock outstanding and entitled to vote at the First Sentry special meeting. Owners of record of First Sentry common stock on the record date are entitled to one vote per share at the First Sentry special meeting.

A quorum of First Sentry shareholders is necessary to have a valid meeting of First Sentry shareholders. The presence, in person or by proxy, of the holders of at least a majority of the shares of First Sentry common stock outstanding and entitled to vote as of the record date is necessary to constitute a quorum at the First Sentry special meeting. Abstentions and brokernon-votes count as present for establishing a quorum. An abstention occurs when a shareholder attends a meeting, either in person or by proxy, but abstains from voting. A brokernon-vote occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power for that particular item and has not received instructions from the beneficial owner. Neither of the proposals to be voted upon at the First Sentry special meeting are routine matters, and brokers, banks and other nominees holding shares in street name will not be permitted to vote on any proposal without instructions from the beneficial holder with respect to that specific proposal. If a beneficial holder of shares of First Sentry common stock does not give the broker, bank or other nominee any voting instructions, the holder’s shares of common stock will not be voted on any proposal.

Required Vote

Approval of the Merger Agreement. Approval of the merger agreement requires that the number of votes cast favoring approval of the merger agreement exceeds the votes cast opposing approval of the merger agreement. Accordingly, we urge you to complete, date and sign the accompanying proxy card and return it promptly in the enclosed postage-paid envelope.

When considering the recommendation of the First Sentry board of directors that First Sentry shareholders vote in favor of approval of the merger agreement, you should be aware that certain of First Sentry’s executive officers and directors have interests in the merger that may be different from, or in addition to, their interests as shareholders and the interests of First Sentry shareholders generally. See “Proposal No. 1 — Approval of the Merger Agreement — Interests of Certain Persons in the Merger” beginning on page 49.

- 24 -

Discretionary Authority to Adjourn Our Special Meeting. In order to approve the proposal to grant discretionary authority to adjourn our special meeting, if necessary, to solicit additional proxies from First Sentry shareholders, the number of votes cast favoring this proposal must exceed the votes cast opposing this proposal.

Abstentions and BrokerNon-Votes.Abstentions, brokernon-votes and any shares that are not voted will have no effect on the outcome of either the proposal to approve the merger agreement or the proposal to adjourn our special meeting, if necessary, to solicit additional proxies from First Sentry shareholders in favor of approval of the merger agreement.

Beneficial Ownership of First Sentry Officers, Directors and Affiliates

On the record date, the directors, executive officers and affiliates of First Sentry beneficially owned 366,763 shares of First Sentry common stock, or approximately 23.16% of the outstanding shares of First Sentry common stock. In addition, the executive officers and directors of First Sentry have entered into voting agreements with WesBanco in which each executive officer or director has agreed to vote his or her First Sentry shares in favor of approval of the merger agreement. As of the record date, there were 190,681 shares of First Sentry common stock subject to these voting agreements, which represent approximately 12.20% of the outstanding shares of First Sentry common stock as of the record date. See “Other Material Agreements Relating to the Merger — Voting Agreements.”

Voting of Proxies

First Sentry shareholders may submit the accompanying proxy by telephone, the Internet or by mail. We urge you to submit your proxy if you do not expect to attend the First Sentry special meeting in person or if you wish to have your First Sentry shares voted by proxy even if you attend the First Sentry meeting. All shares of First Sentry common stock represented at the First Sentry special meeting by properly executed proxies received prior to or at the First Sentry special meeting, and not revoked, will be voted at the First Sentry special meeting in accordance with the instructions on the proxies. If you properly execute a proxy but include no voting instructions, your shares will be voted“FOR” (i) the proposal to approve the merger agreement and (ii) the proposal to approve the adjournment of the First Sentry special meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the First Sentry special meeting to approve the proposal to approve the merger agreement.

If your shares are held in “street name” (i.e., in the name of a broker, bank or other record holder), you must direct the record holder how to vote your shares in connection with the merger. Your broker will send you directions explaining how you can direct your broker to vote.

The First Sentry board of directors does not know of any matters, other than those described in the notice of the First Sentry special meeting, which are to come before the special meeting. If any other matters are properly presented at the special meeting for action, the persons named in the enclosed form of proxy will have the authority to vote on those matters in their discretion.

Revocation of Proxies

If you give a proxy, you have the right to revoke it at any time before it is voted. You may revoke your proxy by (i) filing a written notice of revocation with the Secretary of First Sentry that is received prior to the vote at the First Sentry special meeting and bears a later date than the proxy, (ii) duly executing a later dated proxy card relating to the same First Sentry shares and delivering it to the Secretary of First Sentry before the vote at the First Sentry special meeting, (iii) submitting a later dated proxy by telephone or the Internet, before the vote at the First Sentry special meeting, or (iv) attending the First Sentry special meeting and voting in person. Your attendance at the First Sentry special meeting will not, in and of itself, revoke your proxy. Any written notice of revocation or subsequent dated proxy should be sent to First Sentry Bancshares, Inc., 823 Eighth Street, Huntington, WV 25701, Attention: Corporate Secretary, or hand delivered to the First Sentry Corporate Secretary at that address. For a notice of revocation or later proxy to be valid, it must actually be received by First Sentry prior to the vote of the First Sentry shareholders.

- 25 -

If your First Sentry shares are held by a broker in street name and you wish to change the instructions you have given your broker about how to vote your First Sentry shares, or you wish to attend the First Sentry special meeting and vote in person, you must follow the instructions provided by your broker.

Expenses of Solicitation of Proxies

First Sentry will bear the entire cost of soliciting proxies from First Sentry shareholders. In addition to solicitation by use of the mail, proxies may be solicited by directors, officers and employees of First Sentry in person or by telephone or other means of communication. These directors, officers and employees will not receive any additional compensation but may be reimbursed forout-of-pocket expenses they incur in connection with the solicitation. Arrangements will also be made with brokerage houses, custodians, nominees and fiduciaries for the forwarding of solicitation materials to the beneficial owners of First Sentry common stock held of record by such persons. First Sentry may reimburse these custodians, nominees and fiduciaries for reasonableout-of-pocket expenses they incur.

DO NOT SEND YOUR STOCK CERTIFICATES WITH YOUR PROXY CARD.

Recommendation of First Sentry Board of Directors

The First Sentry board of directors believes that the merger is in the best interests of First Sentry and its shareholders, and unanimously recommends that the shareholders of First Sentry vote:

• “FOR” the proposal to approve the merger agreement; and

• “FOR” the proposal to approve the adjournment of the First Sentry special meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the First Sentry special meeting to approve the proposal to approve the merger agreement.

For a discussion of the factors considered by the First Sentry board of directors in making its recommendation, see “Proposal No. 1 — Approval of the Merger Agreement — First Sentry’s Reasons for the Merger; Recommendation of the First Sentry Board of Directors.”

PROPOSAL NO. 1 — APPROVAL OF THE MERGER AGREEMENT

The following summarizes material provisions of the merger agreement, a copy of which is attached to this proxy statement/prospectus as Annex A and which we incorporate by reference into this document. 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. We encourage you to read carefully the merger agreement in its entirety, as the rights and obligations of the parties are governed by the express terms of the merger agreement and not by this summary or any other information contained in this proxy statement/prospectus. Factual disclosures about WesBanco and First Sentry contained in this proxy statement/prospectus or in WesBanco’s public reports filed with the SEC may supplement, update or modify the factual disclosures about the companies contained in the merger agreement.

This description of the merger agreement in this proxy statement/prospectus has been included to provide you with information regarding the merger agreement’s terms. The merger agreement contains representations, warranties, covenants and agreements made by WesBanco and First Sentry as of specific dates that were made for purposes of that contract between the parties and are subject to qualifications and limitations, including by information in disclosure schedules that the parties exchanged in connection with the execution of the merger agreement. In addition, certain representations and warranties may be subject to contractual standards of materiality different from those generally applicable to shareholders, or may have been used for the purpose of allocating risk between the parties rather than establishing matters as facts. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this proxy statement/prospectus, may have changed since the date of the merger agreement.

General

WesBanco’s and First Sentry’s boards of directors have approved the merger agreement. The merger agreement provides that First Sentry will merge with and into WesBanco, with WesBanco being the surviving corporation. Following the merger, First Sentry Bank, Inc., a West Virginia banking corporation and First Sentry’s wholly-owned subsidiary, will merge with and into WesBanco Bank, a West Virginia banking corporation which is WesBanco’s main operating subsidiary (the “bank merger”). The Articles of Incorporation and Bylaws of WesBanco and WesBanco Bank immediately prior to the merger will constitute the Articles of Incorporation and Bylaws of WesBanco and WesBanco Bank following the merger.

What First Sentry Shareholders Will Receive in the Merger

If the merger is completed, for each share of First Sentry common stock that you own you will receive 1.5869 shares of WesBanco common stock, subject to possible adjustment as described below. We refer to the 1.5869 shares of WesBanco common stock as the “exchange ratio” or the “merger consideration.”

Possible Exchange Ratio Adjustments.The exchange ratio is subject to adjustment in the event that certain termination provisions, based on the market price of WesBanco’s common stock and the value of the Nasdaq Bank Index, are triggered and the First Sentry board of directors elects to terminate the merger agreement. First Sentry’s right to terminate the merger agreement would arise if the average closing price of WesBanco common stock during the fifteen (15) consecutive trading days ending on the Determination Date (as defined below on page 66) is less than $31.10 per share and WesBanco common stock underperforms an index of financial institution stocks, the Nasdaq Bank Index, by more than 20%. However, First Sentry would not have the right to terminate the merger agreement if WesBanco elects to make a compensating adjustment in the exchange ratio. See “Proposal No.1 — Approval of the Merger Agreement — Termination of the Merger Agreement” beginning on page 65 for a description of the possible exchange ratio adjustments that may result from this termination provision.

In addition, the merger agreement provides that the exchange ratio will be adjusted if WesBanco changes the number of shares of WesBanco common stock issued and outstanding prior to the effective time of the

- 27 -

merger as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other like changes in WesBanco’s capitalization.

Effects of the Merger

The merger will become effective as set forth in the articles of merger that will be filed with the West Virginia Secretary of State. At that time, the separate existence of First Sentry will cease and WesBanco will be the surviving corporation. The assets, liabilities and capital of First Sentry will be merged with those of WesBanco and those assets, liabilities and capital will then constitute part of the assets, liabilities and capital of WesBanco. WesBanco will continue to operate under its Articles of Incorporation and Bylaws effective as of immediately prior to the merger, and the officers and directors of WesBanco will continue as the officers and directors of the surviving corporation. The Articles of Incorporation and Bylaws of WesBanco will be unaffected by the merger. The tenure of the directors and officers of WesBanco immediately prior to the merger will be unaffected by the merger.

At the effective time of the merger, each share of First Sentry common stock issued and outstanding immediately prior to the time the merger becomes effective will be converted automatically into the right to receive the merger consideration. Shares of First Sentry common stock held by First Sentry in its treasury or beneficially owned by WesBanco (other than in a fiduciary capacity by them for others) will not be exchanged for the merger consideration in the merger. Instead, these shares will be canceled and retired.

After the merger becomes effective, each certificate evidencing shares of First Sentry common stock will be deemed to evidence only the right to receive the merger consideration and, under certain circumstances, dividends on shares of First Sentry common stock with a record date prior to the completion of the merger and dividends on shares of WesBanco common stock with a record date after the completion of the merger. The holder of an unexchanged certificate will not receive any dividend or other distribution payable by WesBanco until the certificate has been exchanged.

Exchange and Payment Procedures

At least one business day prior to the effective time of the merger, WesBanco will deposit with Computershare Investor Services, LLC, the Exchange Agent, (i) book entry shares representing the aggregate number of shares of WesBanco common stock issuable pursuant to the merger agreement in exchange for all of the shares of First Sentry common stock outstanding immediately prior to the effective time of the merger and (ii) cash to be paid to First Sentry shareholders in lieu of fractional shares of WesBanco common stock.

As soon as practicable after the effective time of the merger and in no event more than seven business days thereafter, the Exchange Agent will mail to each holder of record of First Sentry common stock a letter of transmittal containing instructions for use in surrendering First Sentry stock certificates in exchange for the merger consideration or cash in lieu of fractional shares. After the effective time of the merger, each holder of a First Sentry stock certificate who has surrendered that stock certificate or who has provided customary affidavits and indemnification regarding the loss or destruction of that stock certificate, together with duly executed transmittal materials, to the Exchange Agent, will be entitled to receive the merger consideration for each share of First Sentry common stock and cash in lieu of fractional shares of WesBanco common stock. WesBanco will have no obligation to deliver the merger consideration or cash in lieu of fractional shares to any First Sentry shareholder until the First Sentry shareholder surrenders his First Sentry stock certificates.

If a First Sentry stock certificate has been lost, stolen or destroyed, the Exchange Agent will issue the consideration properly payable under the merger agreement upon receipt of an affidavit of that fact by the shareholder. WesBanco may require the shareholder to post a bond in a reasonable amount as an indemnity against any claim that may be made against WesBanco with respect to the shareholder’s lost, stolen or destroyed First Sentry stock certificate.

- 28 -

First Sentry stock certificates may be exchanged for the merger consideration and cash in lieu of fractional shares of WesBanco common stock through the Exchange Agent for up to 12 months after the completion of the merger. At the end of that period, the Exchange Agent will return any WesBanco shares and cash to WesBanco. Any holders of First Sentry common stock certificates who have not exchanged their certificates for the merger consideration before that date will then be entitled to look only to WesBanco to seek payment of the merger consideration, any cash in lieu of fractional shares of WesBanco common stock and any unpaid dividends or distributions payable to the holder. Neither First Sentry nor WesBanco will be liable to any former holder of First Sentry common stock for any merger consideration that is paid to a public official in accordance with any applicable abandoned property, escheat or similar laws.

Following the effective time of the merger, there will be no transfers on the stock transfer books of First Sentry other than to settle transfers of First Sentry common stock that occurred prior to the effective time of the merger.

Benefit Agreements

401(k) Plan. Pursuant to the terms of the merger agreement, WesBanco has the option to require First Sentry to terminate its 401(k) Plan immediately prior to or at the effective time of the merger, or to merge the First Sentry 401(k) Plan with and into the WesBanco 401(k) Plan. Until the First Sentry 401(k) Plan is terminated or merged, First Sentry will continue to make contributions to the 401(k) Plan in accordance with applicable accruals and in the ordinary course of business. If WesBanco elects to terminate the First Sentry 401(k) Plan, then as soon as practicable following the effective time of the merger, WesBanco will, at each employee’s option, either distribute the account balances to participants or transfer the balances to an eligibletax-qualified retirement plan or individual retirement account as a participant or beneficiary may direct. WesBanco has agreed to permit First Sentry employees who become WesBanco employees following completion of the merger to rollover their account balances to WesBanco’s KSOP.

Severance, Benefits and Outplacement Services for Terminated First Sentry Employees.Employees of First Sentry (other than employees who are parties to employment, severance or change in control agreements) who are not offered the opportunity to continue as employees of WesBanco or WesBanco Bank after the merger, or who are terminated without cause within six months after the merger, will be entitled to receive:

• severance compensation based on the number of years of service with First Sentry and the employee’s weekly rate of pay, subject to certain minimum and maximum amounts;

• accrued benefits, including vacation pay, through the date of separation;

• any rights to continuation of medical coverage to the extent such rights are required under applicable federal or state law and subject to the employee’s compliance with all applicable requirements for such continuation coverage, including payment of all premiums or other expenses related to such coverage; and

• outplacement services with a cost of up to $2,000 for each employee, with such cost to be paid by WesBanco.

Retention Bonus Pool.WesBanco will provide a retention bonus pool for the purposes of retaining the services of employees of First Sentry and its subsidiaries who are key employees through the end of the month during which the conversion of the data processing system of First Sentry occurs. First Sentry’s Chief Executive Officer will determine, subject to approval by WesBanco’s President and Chief Executive Officer, the First Sentry employees eligible to receive retention awards from the retention bonus pool and any criteria for payment, and will determine the final allocation of payments from the retention bonus pool.

Retention Restricted Stock Agreements.WesBanco has entered into agreements with certain First Sentry key employees pursuant to which WesBanco will grant, immediately after and subject to the occurrence of the

- 29 -

effective time, restricted shares of WesBanco common stock which will cliff-vest on the third anniversary of the grant date if such key employee remains employed by WesBanco or WesBanco Bank at that time. Grants under these retention restricted stock agreements will be made and become effective only upon the applicable key employees becoming employees of WesBanco or WesBanco Bank at or after the effective time. No grants under these retention restricted stock agreements will be made if the merger does not occur.

Other Benefit Arrangements.As of the effective time of the merger, WesBanco will honor and assume the separation agreements, employment agreements,non-competition agreements, consulting agreements and change in control agreements in effect with the senior officers of First Sentry and First Sentry Bank, Inc. at the effective time of the merger. See “Interests of Certain Persons in the Merger,” below.

Treatment of First Sentry Stock Options

Options issued by First Sentry to employees and directors to purchase an aggregate of 36,800 shares of First Sentry common stock were outstanding as of the record date. Upon completion of the merger, each outstanding option to purchase shares of First Sentry common stock, whether or not then vested or exercisable, will be cancelled in exchange for the right to receive an amount in cash, without interest, equal to the product of (i) the aggregate number of shares of First Sentry common stock subject to each such stock option, multiplied by (ii) the excess, if any, of $64.00 over the per share exercise price of the First Sentry stock option. The cash payment will be subject to applicable tax withholding.

Background of the Merger

The board of directors and senior management of First Sentry have periodically explored and discussed strategic options available to First Sentry for maintaining its competitiveness and increasing shareholder value. These discussions have included, among other things, remaining independent as well as exploring the merger and acquisition environment for financial institutions and a potential business combination involving First Sentry. Fromtime-to-time, Geoffrey S. Sheils, President and Chief Executive Officer of First Sentry, has been contacted by representatives of larger financial institutions to inquire about First Sentry’s interest in a merger transaction. Mr. Sheils informed the First Sentry board of directors of these preliminary inquiries, but such discussions did not result in any proposals that the board could recommend to First Sentry’s shareholders.

In late December 2016, Mr. Sheils engaged with a representative of a potential acquiror, Company A, in a high-level conversation about a potential strategic transaction involving First Sentry. During the first quarter of 2017, representatives of Company A engaged in a review of financial and other information related to First Sentry.

On April 24, 2017, Mr. Sheils, Robert H. Beymer, the chairman of the First Sentry board, and the chairman of the board and chief executive officer of Company A met to discuss a potential strategic transaction. At its meeting on April 26, 2017, the Strategic Planning Committee of First Sentry’s board recommended to the entire board that First Sentry continue discussions with Company A regarding a potential strategic transaction.

On May 3, 2017, the First Sentry board of directors met to consider the initial proposal from Company A. At the meeting, the First Sentry board of directors authorized Mr. Sheils to enter into anon-binding letter of interest with Company A. In the weeks after the board’s authorization, representatives from Company A and First Sentry engaged in discussions regarding the specific terms of a potential business combination; however, the parties were not able to reach mutual agreement with respect to significant aspects of the proposed combination. On June 20, 2017, after receiving an update on the status of the discussions from Mr. Sheils and Chairman Beymer, the First Sentry board of directors directed First Sentry management to cease discussions with Company A.

On July 18, 2017, in light of the earlier discussions with Company A, the First Sentry board of directors decided to engage Sandler O’Neill & Partners, L.P., or Sandler O’Neill, to conduct a strategic planning session to assist the board in assessing First Sentry’s strategic alternatives.

- 30 -

On August 15, 2017, Sandler O’Neill conducted a strategic planning session with the First Sentry board of directors. Sandler O’Neill’s presentation included assessments of options for First Sentry to grow through acquisitions, remain a similar size and continue operating in the ordinary course of business and enter into a strategic business combination with a larger financial institution. Representatives of Sandler O’Neill provided information on the current market conditions in the banking industry, recent merger and acquisition activity and a preliminary valuation range of First Sentry’s franchise position. Sandler O’Neill’s presentation included a list of potential acquirers that Sandler O’Neill identified as possibly having an interest in entering or expanding in the southwestern West Virginia market by a merger transaction with First Sentry. Important considerations in a potential business combination were discussed, including the type of merger consideration to be received by shareholders, dividend yields, customer and community impact and the regulatory approval process. Representatives of First Sentry and Sandler O’Neill also reviewed other business considerations, including the process for marketing First Sentry for a strategic business combination, if the First Sentry board of directors decided to pursue such a transaction.

After considerable discussion among the members of the board, the First Sentry board decided to pursue a strategy to enter into a business combination through a merger with a larger financial institution. In furtherance of this decision, the First Sentry board of directors authorized representatives of Sandler O’Neill to identify potential merger partners and to coordinate with First Sentry’s senior management in preparing a confidential information memorandum about First Sentry.

On August 21, 2017, First Sentry and Sandler O’Neill executed an engagement letter with respect to the potential merger of First Sentry into a larger financial institution.

During late August and early September 2017, First Sentry’s senior management and representatives of Sandler O’Neill held variousin-person and telephonic meetings to determine a list of potential merger partners, merger criteria and the process and possible timeline for a transaction, and to prepare a confidential information memorandum with respect to First Sentry’s business, operations and market area. First Sentry also populated an electronic data room with documents containing substantial information about First Sentry.

Beginning on September 5, 2017, at the direction of First Sentry management, representatives of Sandler O’Neill began making calls to potential interested financial institutions and circulated a copy of the confidential information memorandum about First Sentry to those financial institutions that executed a customary confidentiality agreement. The terms of the confidential information memorandum requested that interested financial institutions submit an indication of interest by September 28, 2017. WesBanco was among the parties contacted by representatives of Sandler O’Neill and WesBanco executed a confidentiality agreement on September 6, 2017. In total, 12 potential merger partners were contacted, of which 6 signed confidentiality agreements, received the confidential information memorandum and were granted access to First Sentry’s electronic data room.

Four financial institutions submitted initial indications of interest to Sandler O’Neill on or before September 28, 2017, including WesBanco.

On October 2, 2017, the First Sentry board of directors met to consider the indications of interest received by Sandler O’Neill. Representatives of Sandler O’Neill provided information on the number of financial institutions it had contacted and the general levels of interest it received on behalf of First Sentry. During the meeting, members of the First Sentry board asked questions of the representatives of Sandler O’Neill that were present with respect to the marketing process, and Sandler O’Neill responded accordingly. The First Sentry directors and representatives of Sandler O’Neill discussed, in general, the proposed merger consideration offered by the interested parties and the approximate aggregate consideration value to First Sentry’s shareholders of such offers. The First Sentry board, senior management and representatives of Sandler O’Neill also further explored the strategic options available to First Sentry. Following a robust discussion of the four proposals received by Sandler O’Neill, the First Sentry board of directors authorized the representatives of Sandler O’Neill to admit

- 31 -

three of the financial institutions, Company B, Company C and WesBanco, to pursue an additional round of due diligence and, if so desired, to conduct management meetings with the senior management of First Sentry. Each of Company B, Company C and WesBanco conducted further due diligence during the next three weeks and held management meetings with First Sentry senior management during the week of October 23, 2017.

On October 27, 2017, the deadline for receiving final proposals from the remaining three financial institutions, Sandler O’Neill received three final indications of interest. The proposals of WesBanco and Company B were similar with respect to the value of the consideration offered. The third proposal was significantly less than the proposals of Company B and WesBanco.

On October 31, 2017, the First Sentry board of directors met to consider the three indications of interest received by Sandler O’Neill on October 27, 2017. Representatives from Sandler O’Neill and Bowles Rice LLP, or Bowles Rice, First Sentry’s legal counsel, were in attendance at the meeting. Representatives of Sandler O’Neill presented the First Sentry board with information on the relative pricing metrics of transactions announced since January 1, 2016 involving other banking institutions in theMid-Atlantic and Midwest regions with an asset size between $500 million and $1 billion, and the board considered such information. First Sentry’s board of directors discussed the potential benefits of a merger with each of Company B, Company C and WesBanco, and engaged in a thorough discussion on a potential combination with each such financial institution, especially the preliminary merger consideration offered and the results of the marketing process recently undertaken by Sandler O’Neill. The First Sentry board of directors also considered, in general, the impact of the various proposals on First Sentry’s management, employees and community. The board eliminated the proposal from Company C from further consideration because the proposed merger consideration was significantly lower than the consideration offered by Company B and WesBanco. The board reviewed the financial performance, stock performance, market position, and growth prospects of Company B and WesBanco. The board also considered the trading volume of each company’s stock, each company’s historical experience in consummating merger transactions and each company’s proposed plans with respect to First Sentry’s employees and communities. Based upon its assessment of how Company B and WesBanco compared with respect to these factors, and the value and kind of the consideration offered by each, the First Sentry board of directors determined that WesBanco presented the most attractive proposal for First Sentry’s shareholders. The board determined further that a merger with WesBanco potentially provided substantial long-term benefits to First Sentry’s shareholders. The First Sentry board of directors then authorized senior management, Bowles Rice and representatives of Sandler O’Neill to proceed with the negotiation of a definitive merger agreement and related documents with WesBanco. After the First Sentry board meeting, representatives of Sandler O’Neill contacted a representative of D.A. Davidson & Co. (“Davidson”), WesBanco’s financial advisor, to inform Davidson that the First Sentry board had determined to move forward in merger discussions with WesBanco.

On November 1, 2017, Davidson provided an initial draft of the merger agreement to Sandler O’Neill and First Sentry, which delivered the draft to Bowles Rice. Bowles Rice reviewed the draft merger agreement in its entirety, including a voting agreement attached to the draft merger agreement that provided, among other things, that each director and executive officer of First Sentry vote his or her shares of First Sentry common stock in favor of the merger at any meeting of the First Sentry shareholders held to consider and vote on the merger.

Over the next several days, WesBanco and First Sentry, with the assistance of their respective legal and financial advisors, negotiated and agreed on the terms of the merger agreement. During this period, First Sentry and its representatives conducted due diligence on WesBanco utilizing publicly available information as well as certain confidential information the parties made available to First Sentry and its representativeson-site at WesBanco’s headquarters.

On November 8, 2017, First Sentry executive management and representatives of Sandler O’Neill conducted reverse due diligence at WesBanco’s headquarters.

On November 11, 2017, the First Sentry board of directors held a special meeting to consider the proposed merger and the final version of the merger agreement negotiated by its senior management and Bowles Rice.

- 32 -

Bowles Rice briefed the First Sentry board on its discussions with WesBanco’s legal counsel and the material terms of the merger agreement and related documents. Representatives of Sandler O’Neill again provided information on the terms of the proposed transaction and financial information regarding WesBanco, First Sentry and the transaction, information regarding peer companies and comparable transactions and other relevant analyses. The First Sentry board engaged in a lengthy discussion on the proposed merger and the terms of the merger agreement and related documents. First Sentry board members presented questions to Mr. Sheils and representatives of Bowles Rice and Sandler O’Neill regarding the proposed merger and the merger agreement, and Mr. Sheils and First Sentry’s financial and legal advisors responded to the inquiries. In connection with the deliberations by the First Sentry board, Sandler O’Neill rendered to the board its oral opinion (which was subsequently confirmed in writing), as described under the “Proposal No. 1 — Approval of the Merger Agreement – Opinion of First Sentry’s Financial Advisor,” to the effect that as of the date of its opinion and based upon and subject to the procedures followed, assumptions made, matters considered, and the qualifications and limitations on the review undertaken by Sandler O’Neill as set forth in its opinion, the exchange ratio in the merger was fair to the holders of First Sentry common stock from a financial point of view.

After reviewing Sandler O’Neill’s opinion and further discussion of the terms of the merger, and taking into consideration the matters discussed at the meeting, including the factors described under “Proposal No. 1 — Approval of the Merger Agreement — First Sentry’s Reasons for the Merger; Recommendation of the First Sentry Board of Directors”, the First Sentry board determined that the proposed merger with WesBanco and the related transactions as reflected in the merger agreement presented at the meeting were in the best interest of First Sentry and its shareholders. The board voted unanimously to adopt and approve the merger agreement and related transactions and documents, and to recommend approval of the merger agreement to the shareholders of First Sentry.

The Board of Directors of WesBanco held a special meeting on November 13, 2017, which included representatives of its financial advisor, Davidson, as well as representatives of its legal advisors, Phillips, Gardill, Kaiser & Altmeyer, PLLC and K&L Gates, LLP. At such meeting the WesBanco Board reviewed a financial analysis of the transaction prepared and presented by representatives of Davidson and reviewed the terms of the merger agreement with its legal advisors, each of which documents had been provided to the Board in advance of the meeting. This information served to supplement similar financial information and analysis of the terms of the transaction considered by the Wesbanco Board at its regular meeting held on October 26, 2017. Following a period of discussion with management and the advisors present and participating either in person or telephonically, the WesBanco Board of Directors voted unanimously to adopt and approve the merger agreement and related transactions and documents.

After the markets closed on November 13, 2017, WesBanco and First Sentry executed the definitive merger agreement. Shortly thereafter, WesBanco and First Sentry issued a joint press release publicly announcing the transaction following the closing of the financial markets on November 13, 2017.

First Sentry’s Reasons for the Merger; Recommendation of the First Sentry Board of Directors

In reaching its decision to approve the merger and the merger agreement and to recommend that First Sentry shareholders vote for the approval of the merger agreement, the First Sentry board of directors consulted with executive management, Sandler O’Neill, its financial advisor, and Bowles Rice, its legal counsel. The First Sentry board of directors carefully considered the terms of the merger agreement and the value of the merger consideration to be received by First Sentry shareholders and ultimately determined that it was in the best interest of First Sentry and its shareholders for First Sentry to enter into the merger agreement with WesBanco. The First Sentry board of directors believes that partnering with WesBanco will maximize the long-term value of shareholders’ investment in First Sentry, and that the merger will provide the combined company with additional resources necessary to compete more effectively in southwestern West Virginia and southeastern Ohio. In addition, the First Sentry board of directors believes that the customers and communities served by First Sentry 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 First Sentry shareholders vote for the approval of the merger agreement, the First Sentry board of directors considered many factors, including, without limitation, the following:

• The value of the WesBanco common stock consideration being offered to First Sentry shareholders in relation to the market value, book value per share, tangible book value per share, earnings per share and projected earnings per share of First Sentry and WesBanco;

• The fact that the merger consideration represented 2.02 times First Sentry’s tangible book value per share at September 30, 2017;

• The expected future receipt by First Sentry shareholders of significant dividends after completion of the merger as WesBanco shareholders, based on WesBanco’s current and forecasted dividend yield and its history of dividend increases;

• Comparative pro forma analyses of First Sentry, WesBanco and the combined entity, and the earnings per share, dividends and capital levels of each entity;

• WesBanco’s asset size, capital position and financial performance in recent periods, which make WesBanco an attractive merger partner and would give the combined company approximately $10.6 billion in assets;

• The current and prospective environment in which First Sentry operates, including national, regional and local economic conditions, the competitive environment for financial institutions, the increased regulatory burdens on financial institutions; and the uncertainties in the regulatory climate going forward;

• The feasibility of, and the results that could be expected to be obtained if, First Sentry continued to operate independently, including First Sentry’s ability to compete with much larger regionally-based banks and the potential need to eventually raise additional capital that could be dilutive to existing First Sentry shareholders;

• The anticipated future earnings growth of First Sentry compared to the potential future earnings growth of WesBanco and the combined company;

• The anticipated future trading value of First Sentry common stock compared to the value of the common stock consideration offered by WesBanco and the potential future trading value of WesBanco common stock;

• The common stock consideration offered by WesBanco, including the opportunity for First Sentry shareholders to receive shares of WesBanco common stock on atax-free basis for their shares of First Sentry common stock;

• The greater market capitalization and trading liquidity of WesBanco common stock in the event First Sentry shareholders desired to sell the shares of WesBanco common stock to be received by them upon completion of the merger;

• The process conducted by representatives of Sandler O’Neill, First Sentry’s financial advisor, to assist the First Sentry board of directors in structuring the proposed merger with WesBanco;

• The presentation and analyses by Sandler O’Neill, First Sentry’s financial advisor, and Sandler O’Neill’s written opinion dated November 11, 2017, to the effect that, as of such date and based upon and subject to the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Sandler O’Neill as set forth in its opinion, the exchange ratio in the merger agreement was fair to First Sentry’s common shareholders from a financial point of view;

• The analyses presented by Bowles Rice, First Sentry’s outside legal counsel, as to the structure of the merger, the merger agreement, duties of the First Sentry board of directors under applicable law, and the process that First Sentry (including its board of directors) employed in considering all potential strategic transactions including the merger with WesBanco;

- 34 -

• The ability to terminate the merger agreement if (i) the average closing price of WesBanco common stock declines by more than 20% from the closing price on November 9, 2017 and (ii) WesBanco common stock underperforms the NASDAQ Bank Index by more than 20%, all as calculated pursuant to the merger agreement;

• The scale, scope, strength and diversity of operations, product lines and delivery systems that could be achieved by combining First Sentry with WesBanco;

• The additional products offered by WesBanco to its customers, the ability of the combined company to provide comprehensive financial services to its customers, and the potential for operating synergies and cross-marketing of products and services across the combined company;

• The potential value of an expansion of the WesBanco branch network adding First Sentry branch locations in southwestern West Virginia to WesBanco’s existing branch network in Kentucky, Indiana, Ohio, Pennsylvania and West Virginia;

• The shared community banking philosophies of First Sentry and WesBanco, and each entity’s commitment to community service and support of community-basednon-profit organizations and causes;

• The fact that First Sentry directors and executive officers have interests in the merger that are different from, or in addition to, those of other First Sentry shareholders;

• The likelihood of successful integration and operation of the combined company;

• The likelihood of obtaining the governmental approvals needed to complete the transaction;

• The potential cost-saving opportunities resulting from the merger;

• The effects of the merger on First Sentry employees, including the prospects for continued employment and the severance and other benefits agreed to be provided to First Sentry employees; and

• The review by the First Sentry board of directors with its legal and financial advisors of the structure of the merger and the financial and other terms of the merger, including the exchange ratio and the condition that the merger must qualify as a transaction that will permit First Sentry shareholders to receive WesBanco shares in exchange for their First Sentry shares on atax-free basis for federal income tax purposes.

The First Sentry 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, without limitation, the following:

• The challenges of integrating First Sentry’s businesses, operations and employees with those of WesBanco;

• The need to obtain approval by shareholders of First Sentry, as well as governmental approvals, in order to complete the transaction;

• The risks associated with the operations of the combined company including the ability to achieve the anticipated cost savings;

• The risks associated with entry into the merger agreement and conduct of First Sentry’s business before the merger is completed, and the impact that provisions of the merger agreement relating to payment of a termination fee by First Sentry may have on First Sentry receiving superior acquisition offers; and

• That the fixed exchange ratio, by its nature, would not adjust upwards to compensate for declines in WesBanco’s stock price prior to the completion of the merger, meaning that First Sentry shareholders would not be protected against decreases in WesBanco’s stock price prior to the completion of the merger.

- 35 -

The First Sentry board of directors also considered the structural protections included in the merger agreement, such as the ability of First Sentry to terminate the merger agreement if, without limitation:

• The average closing price of WesBanco common stock declines by more than 20% from the closing price on November 9, 2017 and WesBanco common stock underperforms the NASDAQ Bank Index by more than 20%, all as calculated pursuant to the merger agreement;

• WesBanco materially breaches any of its representations, warranties, covenants or agreements under the merger agreement, which material breach cannot be or has not been cured within 30 days after written notice of the breach to WesBanco; or

• Any required approval of any government authority is denied by final nonappealable action of such government authority, or the shareholders of First Sentry do not approve the merger at the First Sentry special meeting.

The First Sentry 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 from a buyer other than WesBanco and considered by First Sentry in compliance with thenon-solicitation provisions of the merger agreement and that would, if consummated, result in a transaction that is more favorable to First Sentry shareholders than the merger. This termination right is conditioned on First Sentry providing notice of the unsolicited acquisition proposal to WesBanco, WesBanco not making a revised offer to First Sentry that is at least as favorable as the unsolicited acquisition proposal and First Sentry paying a $3,000,000break-up fee to WesBanco. The amount of this potential fee was negotiated atarm’s-length and was deemed by the First Sentry board of directors to be reasonable based upon thebreak-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.

The foregoing discussion of the information and factors considered by the First Sentry 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 First Sentry 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 First Sentry board of directors did not undertake to make any specific determination as to whether any factor, or any particular aspect of any factor, supported or did not support its ultimate determination. The First Sentry board of directors based its recommendation on the totality of the information presented. The First Sentry board of directors evaluated the factors described above, including asking questions of First Sentry’s legal and financial advisors. The First Sentry board of directors relied on the experience and expertise of its legal advisors regarding the structure of the merger and the terms of the merger agreement and on the experience and expertise of its financial advisor for quantitative analysis of the financial terms of the merger.

For the reasons set forth above, the First Sentry board of directors unanimously determined that the merger agreement and the transactions contemplated by the merger agreement, are advisable and in the best interests of First Sentry and its shareholders, and unanimously adopted and approved the merger agreement and the transactions contemplated by it. The First Sentry board of directors unanimously recommends that the First Sentry shareholders vote “FOR” the approval of merger agreement.

Opinion of First Sentry’s Financial Advisor

First Sentry retained Sandler O’Neill to act as an independent financial advisor to First Sentry’s board of directors in connection with First Sentry’s consideration of a possible business combination. Sandler O’Neill is a nationally recognized investment banking firm whose principal business specialty is financial institutions. In the ordinary course of its investment banking business, Sandler O’Neill is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

Sandler O’Neill acted as an independent financial advisor in connection with the proposed transaction and participated in certain of the negotiations leading to the execution of the merger agreement. At the November 11, 2017 meeting at which First Sentry’s board of directors considered and discussed the terms of the merger agreement and the merger, Sandler O’Neill delivered to First Sentry’s board of directors its oral opinion, which was subsequently confirmed in writing, to the effect that, as of November 11, 2017, the exchange ratio provided for in the merger agreement was fair to the holders of First Sentry common stock from a financial point of view.The full text of Sandler O’Neill’s opinion is attached as Annex B to this proxy statement/prospectus. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Sandler O’Neill in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the full text of the opinion. Holders of First Sentry common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

Sandler O’Neill’s opinion speaks only as of the date of the opinion. The opinion was directed to First Sentry’s board of directors in connection with its consideration of the merger agreement and the merger and does not constitute a recommendation to any shareholder of First Sentry as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the merger agreement and the merger. Sandler O’Neill’s opinion was directed only to the fairness, from a financial point of view, of the exchange ratio to the holders of First Sentry common stock and does not address the underlying business decision of First Sentry to engage in the merger, the form or structure of the merger or any other transactions contemplated in the merger agreement, the relative merits of the merger as compared to any other alternative transactions or business strategies that might exist for First Sentry or the effect of any other transaction in which First Sentry might engage.Sandler O’Neill did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the merger by any officer, director or employee of First Sentry or WesBanco, Inc. (or, for the purposes of this section, “WesBanco”), or any class of such persons, if any, relative to the compensation to be received in the merger by any other shareholder, including the exchange ratio to be received by the holders of First Sentry common stock. Sandler O’Neill’s opinion was approved by Sandler O’Neill’s fairness opinion committee.

In connection with its opinion, Sandler O’Neill reviewed and considered, among other things:

• an execution copy of the Agreement, dated as of November 13, 2017;

• certain publicly available financial statements and other historical financial information of First Sentry and subsidiary of First Sentry that Sandler O’Neill deemed relevant;

• certain publicly available financial statements and other historical financial information of WesBanco that Sandler O’Neill deemed relevant

• certain internal financial projections for First Sentry for the year ending December 31, 2017 as well as an estimated annual earnings growth rate for the years thereafter, as provided by the senior management of First Sentry;

• certain internal financial projections for WesBanco for the years ending December 31, 2017 through December 31, 2020, as well as an estimated long-term earnings per share growth rate and estimated dividends per share for the years thereafter, as provided by the senior management of WesBanco;

• publicly available mean and median analyst earnings per share estimates for WesBanco for the years ending December 31, 2017 through December 31, 2019;

• the pro forma financial impact of the merger on WesBanco based on certain assumptions relating to purchase accounting adjustments, cost savings and transaction expenses, as well as earnings per share estimates for First Sentry for the years ending December 31, 2018 and December 31, 2019 and a long-term annual growth rate for First Sentry for the years thereafter, and earnings per share estimates for WesBanco for the years ending December 31, 2018 through December 31, 2020 as well as a long-term

- 37 -

annual growth rate for WesBanco for the years thereafter, as provided by the senior management of WesBanco;

• the publicly reported historical price and trading activity for WesBanco common stock, including a comparison of certain stock market information for WesBanco common stock and certain stock indices as well as publicly available information for certain other similar companies, the securities of which are publicly traded;

• a comparison of certain financial information for First Sentry and WesBanco with similar financial institutions for which information is publicly available;

• the financial terms of certain recent business combinations in the banking industry (on a regional and nationwide basis), to the extent publicly available;

• the current market environment generally and the banking environment in particular; and

• such other information, financial studies, analyses and investigations and financial, economic and market criteria as Sandler O’Neill considered relevant.

Sandler O’Neill also discussed with certain members of the senior management of First Sentry and its representatives the business, financial condition, results of operations and prospects of First Sentry and held similar discussions with certain members of the senior management of WesBanco and its representatives regarding the business, financial condition, results of operations and prospects of WesBanco.

In performing its review, Sandler O’Neill relied upon the accuracy and completeness of all of the financial and other information that was available to and reviewed by Sandler O’Neill from public sources, that was provided to Sandler O’Neill by First Sentry or WesBanco or their respective representatives or that was otherwise reviewed by Sandler O’Neill, and Sandler O’Neill assumed such accuracy and completeness for purposes of rendering its opinion without any independent verification or investigation. Sandler O’Neill relied on the assurances of the respective managements of First Sentry and WesBanco that they were not aware of any facts or circumstances that would have made any of such information inaccurate or misleading. Sandler O’Neill was not asked to and did not undertake an independent verification of any of such information and Sandler O’Neill did not assume any responsibility or liability for the accuracy or completeness thereof. Sandler O’Neill did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of First Sentry, or WesBanco, or any of their respective subsidiaries, nor was Sandler O’Neill furnished with any such evaluations or appraisals. Sandler O’Neill rendered no opinion or evaluation on the collectability of any assets or the future performance of any loans of First Sentry or WesBanco. Sandler O’Neill did not make an independent evaluation of the adequacy of the allowance for loan losses of First Sentry or WesBanco or the combined entity after the merger and Sandler O’Neill did not review any individual credit files relating to First Sentry or WesBanco. Sandler O’Neill assumed, with First Sentry’s consent, that the respective allowances for loan losses for both First Sentry and WesBanco were adequate to cover such losses and would be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Sandler O’Neill used certain internal financial projections for First Sentry for the year ending December 31, 2017 as well as an estimated annual earnings growth rate for the years thereafter, as provided by the senior management of First Sentry. In addition, Sandler O’Neill used certain internal financial projections for WesBanco for the years ending December 31, 2017 through December 31, 2020, as well as an estimated long-term earnings per share growth rate and estimated dividends per share for the years thereafter, as provided by the senior management of WesBanco. Sandler O’Neill also received and used in its pro forma analyses certain assumptions relating to purchase accounting adjustments, cost savings and transaction expenses, as well as earnings per share estimates for First Sentry for the years ending December 31, 2018 and December 31, 2019 and a long-term annual growth rate for First Sentry for the years thereafter, and earnings per share estimates for WesBanco for the years ending December 31, 2018 through December 31, 2020 as well as a long-term annual growth rate for WesBanco for the years thereafter, as provided by the management of

- 38 -

WesBanco. With respect to the foregoing information, the respective managements of First Sentry and WesBanco confirmed to Sandler O’Neill that such information reflected the best currently available projections, estimates and judgments of those respective managements as to the future financial performance of First Sentry and WesBanco, respectively, and the other matters covered thereby, and Sandler O’Neill assumed that the future financial performance reflected in such information would be achieved. Sandler O’Neill expressed no opinion as to such information, or the assumptions on which such information was based. Sandler O’Neill also assumed that there had been no material change in the respective assets, financial condition, results of operations, business or prospects of First Sentry or WesBanco since the date of the most recent financial statements made available to Sandler O’Neill. Sandler O’Neill assumed in all respects material to its analysis that First Sentry and WesBanco would remain as going concerns for all periods relevant to Sandler O’Neill’s analysis.

Sandler O’Neill also assumed, with First Sentry’s consent, that (i) each of the parties to the merger agreement would comply in all material respects with all material terms and conditions of the merger agreement and all related agreements, that all of the representations and warranties contained in such agreements were true and correct in all material respects, that each of the parties to such agreements would perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements were not and would not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on First Sentry, WesBanco or the merger or any related transaction, (iii) the merger and any related transaction would be consummated in accordance with the terms of the merger agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements, and (iv) the merger would qualify as atax-free reorganization for federal income tax purposes. Finally, with First Sentry’s consent, Sandler O’Neill relied upon the advice that First Sentry received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Merger and the other transactions contemplated by the merger agreement. Sandler O’Neill expressed no opinion as to any such matters.

Sandler O’Neill’s opinion was necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to Sandler O’Neill as of, the date thereof. Events occurring after the date thereof could materially affect Sandler O’Neill’s opinion. Sandler O’Neill has not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events occurring after the date thereof. Sandler O’Neill expressed no opinion as to the trading value of WesBanco common stock at any time or what the value of WesBanco common stock would be once it is actually received by the holders of First Sentry common stock.

In rendering its opinion, Sandler O’Neill performed a variety of financial analyses. The summary below is not a complete description of the analyses underlying Sandler O’Neill’s opinion or the presentation made by Sandler O’Neill to First Sentry’s board of directors, but is a summary of all material analyses performed and presented by Sandler O’Neill. The summary includes information presented in tabular format.In order to fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses.The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Sandler O’Neill believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses to be considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Sandler O’Neill’s comparative analyses described below is identical to First Sentry or WesBanco and no transaction is identical to the merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or merger transaction values, as the

- 39 -

case may be, of First Sentry and WesBanco and the companies to which they are being compared. In arriving at its opinion, Sandler O’Neill did not attribute any particular weight to any analysis or factor that it considered. Rather, Sandler O’Neill made qualitative judgments as to the significance and relevance of each analysis and factor. Sandler O’Neill did not form an opinion as to whether any individual analysis or factor (positive or negative) considered in isolation supported or failed to support its opinion, rather, Sandler O’Neill made its determination as to the fairness of the exchange ratio on the basis of its experience and professional judgment after considering the results of all its analyses taken as a whole.

In performing its analyses, Sandler O’Neill also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which are beyond the control of First Sentry, WesBanco and Sandler O’Neill. The analyses performed by Sandler O’Neill are not necessarily indicative of actual values or future results, both of which may be significantly more or less favorable than suggested by such analyses. Sandler O’Neill prepared its analyses solely for purposes of rendering its opinion and provided such analyses to First Sentry’s board of directors at its November 11, 2017 meeting. Estimates on the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Sandler O’Neill’s analyses do not necessarily reflect the value of First Sentry common stock or the prices at which First Sentry common stock or WesBanco common stock may be sold at any time. The analyses of Sandler O’Neill and its opinion were among a number of factors taken into consideration by First Sentry’s board of directors in making its determination to approve the merger agreement and should not be viewed as determinative of the exchange ratio or the decision of First Sentry’s board of directors or management with respect to the fairness of the merger. The type and amount of consideration payable in the merger were determined through negotiation between First Sentry and WesBanco.

Summary of Implied Exchange Ratio and Implied Transaction Metrics.Sandler O’Neill reviewed the financial terms of the proposed merger. As more fully described in the merger agreement, at the effective time, each share of First Sentry common stock issued and outstanding prior to the effective time, except for certain shares of First Sentry common shares as specified in the merger agreement, will be converted into the right to receive 1.5869 shares of common stock of WesBanco. Based on the15-day average closing price of WesBanco common stock on November 9, 2017 of $40.33, Sandler O’Neill calculated an implied transaction price per share of $64.00 and an aggregate implied transaction value of approximately $101.4 million, assuming 1,563,169 First Sentry common shares outstanding and 36,800 options with a weighted average strike price of $25.79 of as of November 9, 2017. Based upon historical financial information for First Sentry as of or for the last twelve months (“LTM”) ended September 30, 2017, Sandler O’Neill calculated the following implied transaction metrics:

Transaction Price / Book Value Per Share of First Sentry	191	%
Transaction Price / Tangible Book Value Per Share of First Sentry	202	%
Transaction Price / Last Twelve Months Earnings Per Share of First Sentry	16.7x
Tangible Book Premium / Core Deposits1	12.0	%
Market Premium to First Sentry’s15-Day Volume Weighted Average Price2, as of November 9, 2017	77.8	%

First Sentry Net Present Value Analyses.Sandler O’Neill performed an analysis that estimated the net present value per First Sentry common share assuming First Sentry performed in accordance with internal financial projections for the year ending December 31, 2017, as provided by the management of First Sentry, as well as an estimated long-term earnings per share growth rate for the years thereafter, as provided by the senior

- 41 -

management of First Sentry. To approximate the terminal value of a share of First Sentry common stock at December 31, 2021, Sandler O’Neill applied price to 2021 earnings per share multiples ranging from 12.0x to 22.0x and price to December 31, 2021 tangible book value per share multiples ranging from 120% to 170%. The terminal values were then discounted to present values using different discount rates ranging from 9.0% to 15.0% which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of First Sentry common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per First Sentry common share of $35.91 to $78.51 when applying multiples of earnings per share and $34.21 to $58.56 when applying multiples of tangible book value per share.

Sandler O’Neill also considered and discussed with the First Sentry board of directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to net income. To illustrate this impact, Sandler O’Neill performed a similar analysis assuming First Sentry’s earnings per share varied from 15% above projections to 15% below projections. This analysis resulted in the following range of values for each First Sentry common share, applying the price to 2021 earnings per share multiples range of 12.0x to 22.0x referred to above and a discount rate of 12.95%.

Sandler O’Neill noted that the net present value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

WesBanco Net Present Value Analyses.Sandler O’Neill performed an analysis that estimated the net present value per share of WesBanco common stock assuming certain internal financial projections for

WesBanco for the years ending December 31, 2017 through December 31, 2020, as well as an estimated long-term earnings per share growth rate and estimated dividends per share for the years thereafter, as provided by the senior management of WesBanco. To approximate the terminal value of a share of WesBanco common stock at December 31, 2021, Sandler O’Neill applied price to 2021 earnings per share multiples ranging from 16.0x to 20.0x and price to December 31, 2021 tangible book value per share multiples ranging from 180% to 240%. The terminal values were then discounted to present values using different discount rates ranging from 7.0% to 13.0% chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of WesBanco common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of WesBanco common shares of $30.53 to $46.61 when applying multiples of earnings per share and $30.41 to $49.25 when applying multiples of tangible book value per share.

Sandler O’Neill also considered and discussed with the First Sentry board of directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to net income. To illustrate this impact, Sandler O’Neill performed a similar analysis assuming WesBanco’s earnings per share varied from 15% above projections to 15% below projections. This analysis resulted in the following range of per share values for WesBanco common stock, applying the price to 2021 earnings per share multiples range of 16.0x to 20.0x referred to above and a discount rate of 9.70%.

Annual Estimate Variance	Earnings Per Share Multiples
	16.0x		17.0x		18.0x		19.0x		20.0x

Pro Forma Merger Analysis.Sandler O’Neill analyzed certain potential pro forma effects of the merger. In performing this analysis, Sandler O’Neill utilized the following information and assumptions: (i) the merger closes on March 31, 2017; (ii) the pro forma financial impact of the merger on WesBanco based on certain assumptions relating to purchase accounting adjustments, cost savings and transaction expenses, as well as earnings per share estimates for First Sentry for the years ending December 31, 2018 and December 31, 2019 and a long-term annual growth rate for First Sentry for the years thereafter, and earnings per share estimates for WesBanco for the years ending December 31, 2018 through December 31, 2020 as well as a long-term annual growth rate for WesBanco for the years thereafter, as provided by the senior management of WesBanco. The analysis indicated that the merger could be accretive to WesBanco’s earnings per share (excludingone-time transaction costs and expenses) in the years ended December 31, 2018 through December 31, 2021, and first accretive to WesBanco’s estimated tangible book in the year ended December 31, 2020.

In connection with this analysis, Sandler O’Neill considered and discussed with the First Sentry board of directors how the analysis would be affected by changes in the underlying assumptions, including the impact of final purchase accounting adjustments determined at the closing of the transaction, and noted that the actual results achieved by the combined company may vary from projected results and the variations may be material.

Sandler O’Neill’s Relationship.Sandler O’Neill acted as First Sentry’s financial advisor in connection with the merger and will receive a fee for its services in an amount equal to 1.5% of the aggregate purchase price, which fee at the time of announcement was approximately $1.6 million. A significant portion of Sandler O’Neill’s transaction fee is contingent upon consummation of the merger. Sandler O’Neill also received a fee for rendering its opinion in an amount equal to $150,000, which fairness opinion fee will be credited in full towards the portion of the fee becoming due and payable to Sandler O’Neill on the day of closing of the merger. First Sentry has also agreed to indemnify Sandler O’Neill against certain claims and liabilities arising out of Sandler O’Neill’s engagement and to reimburse Sandler O’Neill for certain of itsout-of-pocket expenses incurred in connection with Sandler O’Neill’s engagement. In the two years preceding the date of Sandler O’Neill’s opinion, Sandler O’Neill did not provide any other investment banking services to First Sentry nor did Sandler O’Neill provide any investment banking services to WesBanco in the two years preceding the date thereof. In the ordinary course of Sandler O’Neill’s business as a broker-dealer, Sandler O’Neill may purchase securities from and sell securities to WesBanco and its affiliates. Sandler O’Neill may also actively trade the equity and debt securities of WesBanco or its affiliates for Sandler O’Neill’s own account and for the accounts of Sandler O’Neill’s customers.

Certain WesBanco Prospective Financial Information

WesBanco does not make public disclosure of forecasts or projections of its expected financial performance because of, among other things, the inherent difficulty of accurately predicting financial performance for future periods and the risk that the underlying assumptions and estimates may prove incorrect. In connection with the merger, however, WesBanco management provided certain limited unaudited prospective financial information for WesBanco on a stand-alone basis, without giving effect to the merger, to First Sentry for purposes of considering and evaluating the merger and also to First Sentry’s financial advisor for purposes of the pro forma financial impact analysis and the WesBanco net present value analysis performed by First Sentry’s financial advisor in connection with its opinion to the First Sentry board of directors.

The prospective financial information for WesBanco reflect numerous estimates and assumptions with respect to industry performance, general business, economic, regulatory, market and financial conditions and other future events, as well as matters specific to WesBanco’s business, all of which are inherently uncertain and difficult to predict and many of which are beyond WesBanco’s control. The prospective financial information is subjective in many respects and thus is susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. The prospective financial information may also be affected by WesBanco’s ability to achieve strategic goals, objectives and targets over the applicable periods. As such, the prospective financial information constitutes forward-looking information and is subject to risks and uncertainties, including the various risks set forth in the sections of this proxy statement/prospectus entitled

- 47 -

“Cautionary Statement Concerning Forward-Looking Statements” and “Risk Factors” and in WesBanco’s Annual Report on Form10-K for the fiscal year ended December 31, 2016 and the other reports filed by WesBanco with the SEC.

The prospective financial information for WesBanco was generally not prepared with a view toward public disclosure or complying with GAAP, the published guidelines of the SEC regarding projections or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. Neither WesBanco’s independent registered public accounting firm, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the prospective financial information included below, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and they assume no responsibility for, and disclaim any association with, the prospective financial information. Furthermore, the prospective financial information does not take into account any circumstances or events occurring after the date prepared.

You are strongly cautioned not to place undue reliance on the prospective financial information set forth below. The inclusion of the prospective financial information in this proxy statement/prospectus should not be regarded as an indication that any of WesBanco, First Sentry or their affiliates, advisors or representatives considered or consider the prospective financial information to be necessarily predictive of actual future events, and the prospective financial information should not be relied upon as such. None of WesBanco, First Sentry or their respective affiliates, advisors, officers, directors or representatives can give any assurance that actual results will not differ from the prospective financial information, and none of them undertakes any obligation to update or otherwise revise or reconcile the prospective financial information to reflect circumstances existing after the date such information was prepared or to reflect the occurrence of future events even in the event that any or all of the assumptions underlying the prospective financial information are shown to be in error. None of WesBanco, First Sentry or their respective affiliates, advisors or representatives makes any representation to any shareholder regarding the projections. The prospective financial information is not being included in this proxy statement/prospectus to influence a shareholder’s decision regarding how to vote on any given proposal, but because the prospective financial information was provided to First Sentry and its financial advisor.

In light of the foregoing, and considering that the First Sentry special meeting will be held several months after the prospective financial information was prepared, as well as the uncertainties inherent in any forecasted information, First Sentry shareholders are cautioned not to place unwarranted reliance on such information, and WesBanco urges all First Sentry shareholders to review WesBanco’s most recent SEC filings for a description of WesBanco’s reported financial results. See “Where You Can Find More Information” on page 84 of this proxy statement/prospectus.

WesBanco provided First Sentry and its financial advisor with a projected EPS for WesBanco for each of the following fiscal years as follows:

2017 — $2.42

2018 — $2.52

2019 — $2.59

2020 — $2.61

For fiscal years after 2020, WesBanco provided an estimated long-term EPS growth rate for WesBanco of 5.5%.

None of First Sentry, WesBanco or their respective affiliates, advisors or representatives makes any representation to any shareholder regarding the projections. The prospective financial information is not being included in this proxy statement/prospectus to influence a shareholder’s decision regarding how to vote on any given proposal, but because the prospective financial information was provided to Sandler O’Neill.

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

First Sentry provided Sandler O’Neill with a projected EPS for First Sentry of $1.10 for the fourth quarter of 2017. For fiscal years after 2017, First Sentry provided an estimated long-term EPS growth rate for First Sentry of 5.0%.

Interests of Certain Persons in the Merger

In considering the recommendation of the First Sentry board of directors with respect to the merger agreement, you should be aware that certain persons, including the directors and executive officers of First

- 49 -

Sentry, have interests in the merger in addition to their interests as shareholders of First Sentry generally. The First Sentry board of directors was aware of these interests and considered them in approving the merger agreement and the transactions contemplated thereby. As described in more detail below, these interests include certain payments and benefits that may be provided to certain executive officers upon completion of the merger.

Cash Payment for Outstanding Options. First Sentry as agreed to take the action necessary so that all First Sentry stock options outstanding and unexercised at the time of the merger, whether or not vested, will be cancelled, and instead the option holders will be paid cash in an amount equal to the product of (i) the number of shares of First Sentry common stock subject to each such option at the closing and (ii) an amount equal to the excess, if any, of $64.00 over the exercise price per share of the option, net of any cash which must be withheld under federal and state income and employment tax requirements. As of the date of this proxy statement/prospectus, the directors and executive officers of First Sentry and First Sentry Bank, Inc. as a group held options to purchase an aggregate of 36,800 shares of First Sentry common stock. If none of these options are exercised prior to completion of the merger, the directors and executive officers of First Sentry and First Sentry Bank, Inc. as a group will receive an aggregate of $1.4 million upon cancellation of their stock options.

Retention Restricted Stock Agreements.WesBanco has entered into agreements with certain First Sentry key employees pursuant to which WesBanco will grant, immediately after and subject to the occurrence of the effective time, restricted shares of WesBanco common stock which will cliff-vest on the third anniversary of the grant date if such key employee remains employed by WesBanco or WesBanco Bank at that time. Grants under these retention restricted stock agreements will be made and become effective only upon the applicable key employees becoming employees of WesBanco or WesBanco Bank at or after the effective time. No grants under these retention restricted stock agreements will be made if the merger does not occur.

- 51 -

Advisory Board.Each member of the First Sentry board of directors at the effective time of the merger, will be appointed to a newly-created advisory board for WesBanco Bank for the Huntington, West Virginia market. Each advisory board member will serve for at least one year and will receive the same annual compensation they received for service on the First Sentry and First Sentry Bank, Inc. boards of directors for the fiscal year ended December 31, 2016.

Indemnification.WesBanco has agreed that, following the effective time of the merger, it will indemnify, defend and hold harmless the current and former directors and officers of First Sentry against all costs, expenses, claims, damages or liabilities arising out of actions or omissions occurring at or prior to the effective time of the merger to the fullest extent permitted by applicable law, including provisions relating to advances of expenses. The merger agreement further provides that WesBanco will obtain four years of extended liability insurance to provide for continued coverage of First Sentry’s directors and officers with respect to matters occurring prior to the effective time of the merger, subject to a cap that limits the annual amount that WesBanco must expend for such liability insurance to no more 150% of the annual amount expended by First Sentry prior to the effective time of the merger.

Ownership by First Sentry Officers and Directors.As of the record date, the directors and executive officers of First Sentry beneficially owned, in the aggregate, 366,763 shares of First Sentry common stock, representing approximately 23.16% of the outstanding shares of First Sentry common stock. Directors and executive officers of First Sentry will be treated the same as other First Sentry shareholders with respect to their ownership of outstanding First Sentry common stock.

Regulatory Approvals

Completion of the merger and the bank merger are each subject to certain federal and state bank regulatory agency filings and approvals. WesBanco and First Sentry cannot complete the merger and the bank merger unless and until WesBanco and First Sentry receive all necessary prior approvals from the applicable bank regulatory authorities. WesBanco and First Sentry have agreed to use their best efforts to obtain all such necessary prior approvals required to consummate the transactions contemplated by the merger agreement. Neither WesBanco nor First Sentry can predict whether or when WesBanco and First Sentry will obtain the required regulatory approvals, waivers or exemptions necessary for the merger of WesBanco with First Sentry and the merger of WesBanco Bank with First Sentry Bank, Inc. As of the date of this proxy statement/prospectus, we have not yet received the required regulatory approvals.

Federal Deposit Insurance Corporation. The bank merger is subject to the approval by the Federal Deposit Insurance Corporation (“FDIC”) under the Bank Merger Act. In granting its approval under the Bank Merger Act, the FDIC must consider, among other factors, the competitive effect of the merger, the managerial and financial resources and future prospects of the merging banks, the effect of the merger on the convenience and needs of the communities to be served, including the records of performance of the merging banks in meeting the credit needs of the communities under the Community Reinvestment Act, the effectiveness of the merging banks in combating money laundering activities, and the risk that would be posed by the merger to the stability of the United States banking or financial system. Applicable regulations require publication of notice of the application and an opportunity for the public to comment on the application in writing. WesBanco filed the requisite bank merger application with the FDIC on December 13, 2017.

The bank merger (the completion of which is not a condition to the merger) may not be consummated until 30 days after the approval of the FDIC (or such shorter period as the FDIC may prescribe with the concurrence of the United States Department of Justice, but not less than 15 days), during which time the Department of Justice may challenge the bank merger on antitrust grounds.

Federal Reserve Board.The merger requires the approval of the Federal Reserve Board pursuant to the Bank Holding Company Act of 1956, as amended, unless the Federal Reserve Board is willing to grant a waiver pursuant to its regulations allowing for such waivers. On December 20, 2017 the Federal Reserve Board granted such a waiver.

- 52 -

West Virginia Division of Financial Institutions.Both the merger and the bank merger require the approval of the West Virginia Division of Financial Institutions. WesBanco filed the requisite application for approval of the merger and bank merger with the West Virginia Division of Financial Institutions on December 13, 2017.

Other Requisite Approvals, Notices and Consents. Neither First Sentry nor WesBanco is aware of any other regulatory approvals, notices or consents required for completion of the merger other than those we describe above. Should any other approvals, notices or consents be required, First Sentry and WesBanco presently contemplate that they would seek to obtain such approvals or consents and give such notices. There can be no assurance, however, that WesBanco and First Sentry can obtain any other approvals or consents, if required.

There can be no assurance that the regulatory authorities described above will approve the merger or the bank merger, and if such mergers are approved, there can be no assurance as to the date on which WesBanco and First Sentry will receive such approvals. The mergers cannot proceed in the absence of the receipt of all requisite regulatory approvals.

The approval of any application merely implies the satisfaction of regulatory criteria for approval. Any such approval does not include review of the merger from the standpoint of the adequacy of the merger consideration our shareholders will receive upon the merger. Further, regulatory approvals do not constitute an endorsement or recommendation of the merger.

Dissenters’ or Appraisal Rights

If the merger is consummated, holders of record of First Sentry common stock who follow the procedures specified by Sections31D-13-1301 through31D-13-1331 of the West Virginia Business Corporation Act 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. First Sentry 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 First Sentry common stock will result in a waiver of the shareholder’s right to demand payment for his or her shares.

The following summary of the provisions of Sections31D-13-1301 through31D-13-1331 of the West Virginia Business Corporation Act is not intended to be a complete statement of such provisions, the full text of which is attached asAnnex C to this proxy statement/prospectus, and is qualified in its entirety by reference thereto.

A holder of First Sentry common stock electing to exercise appraisal rights must deliver to First Sentry 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 sent 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 West Virginia Business Corporation Act.

Within 10 days after the effective time of the merger, WesBanco, 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

- 53 -

when share certificates, if any, must be deposited, (ii) supply a form for demanding payment in compliance withSection 31D-13-1322 of the West Virginia Business Corporation Act, (iii) set a date by which WesBanco must receive the demand for payment, which may not be less than 40 nor more than 60 days after the date the notice is sent, (iv) state WesBanco’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 WesBanco by such specified date, (vi) state that, if requested in writing, WesBanco 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 Sections31D-13-1301 through31D-13-1331 of the West Virginia Business Corporation Act, inclusive.

Within the time period set forth in the notice, the dissenting shareholder must (i) sign and return the form sent by WesBanco 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, WesBanco, 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. WesBanco 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 First Sentry’s accounting records that complies withSection 31D-13-1324(b) of the West Virginia Business Corporation Act, (ii) a statement of WesBanco’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 under31D-13-1326 of the West Virginia Business Corporation Act 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 WesBanco’s obligations under the West Virginia Business Corporation Act.

Following receipt of payment, a dissenting shareholder, within 30 days, may send WesBanco 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 WesBanco’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 WesBanco’s payment for the shareholder’s shares. If a demand for payment remains unsettled, WesBanco will petition the court to determine fair value and accrued interest. If WesBanco fails to commence an action within 60 days following the receipt of a dissenting shareholder’s demand, WesBanco 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 WesBanco. In addition, reasonable fees and

- 54 -

expenses of counsel and experts will be determined by the court and may be assessed against WesBanco 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.

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 asAnnex C.

Shares to be Issued by WesBanco in the Merger; Ownership of WesBanco after the Merger

WesBanco will issue a maximum of approximately 2,538,991 shares of its common stock to First Sentry shareholders in connection with the merger, based on the number of (1) shares of First Sentry common stock outstanding on the record date and (2) shares of First Sentry common stock potentially issuable pursuant to outstanding stock options, assuming no adjustment to the exchange ratio is made. Assuming that WesBanco issues that maximum number of shares, those shares would constitute approximately 5.5% of the outstanding stock of WesBanco after the merger, based on the number of shares of WesBanco common stock outstanding on the record date. The WesBanco shares to be issued in the merger will be listed for trading on the Nasdaq Global Select Market under the symbol “WSBC.”

Management Following the Merger

Each of the current directors and executive officers of WesBanco will continue to serve in those capacities following the merger. For information as to their identities, backgrounds, compensation and certain other matters relating to WesBanco’s directors and executive officers, please refer to WesBanco’s proxy statement for its 2017 annual meeting of shareholders, which is incorporated by reference herein. See ‘Where You Can Find More Information.”

Accounting Treatment

In accordance with Financial Accounting Standards Board, Accounting Standards Codification 805, Business Combinations,WesBanco will account for the merger as an “acquisition.” Under acquisition accounting, First Sentry’s assets, including identifiable intangible assets, and liabilities, including executory contracts and other commitments, as of the effective time of the merger will be recorded at their respective fair values and added to the balance sheet of WesBanco. Any excess of the purchase price over the fair values of net assets acquired will be recorded as goodwill. Financial statements of WesBanco issued after the merger will include these initial fair values (adjusted for subsequent amortization or accretion) and First Sentry’s results of operations from the effective time of the merger.

Material U.S. Federal Income Tax Consequences of the Merger

The following discussion and legal conclusions contained herein constitute and represent the opinion of K&L Gates LLP, counsel to WesBanco, and the opinion of Bowles Rice LLP, counsel to First Sentry, as to the material U.S. federal income tax consequences of the merger to U.S. holders (as defined below) of First Sentry common stock that exchange their shares of First Sentry common stock for shares of WesBanco common stock in the merger. The discussion is based on the Code, Treasury regulations promulgated thereunder, administrative rulings and practice, and judicial decisions, all as currently in effect and all of which are subject to change (possibly with retroactive effect) and to differing interpretations. Any such change could affect the accuracy of the statements and conclusions set forth in this discussion. This discussion applies only to First Sentry shareholders that hold First Sentry common stock as a capital asset within the meaning of Section 1221 of the

- 55 -

Code (generally, property held for investment). This discussion does not address all aspects of U.S. federal taxation that may be relevant to a particular shareholder in light of personal circumstances or to shareholders subject to special treatment under U.S. federal income tax laws, including:

• banks, financial institutions or trusts;

• tax-exempt organizations;

• insurance companies;

• dealers in securities or foreign currencies;

• traders in securities who elect to apply amark-to-market method of accounting;

• pass-through entities and investors in such entities (such as S corporations and partnerships);

• real estate investment trusts;

• regulated investment companies;

• mutual funds;

• foreign persons;

• persons whose functional currency is not the U.S. dollar;

• U.S. expatriates;

• shareholders who received their First Sentry common stock through the exercise of employee stock options, holders of options to acquire First Sentry common stock, or holders who acquired their First Sentry common stock through atax-qualified retirement plan or otherwise as compensation; and

• shareholders who hold First Sentry common stock as part of a hedge, straddle, constructive sale, conversion transaction or other integrated investment.

In addition, this discussion does not address any alternative minimum tax or any state, local, foreign, ornon-income tax consequences of the merger, nor does it address any tax consequences arising under the unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010.

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

If a partnership or other entity taxed as a partnership for U.S. federal income tax purposes holds First Sentry common stock, the tax treatment of a partner in the partnership will depend upon the status of the partner and the activities of the partnership. Partnerships and partners in such a partnership should consult their tax advisors regarding the tax consequences of the merger to them.

Each holder of First Sentry common stock should consult its tax advisor with respect to the particular tax consequences of the merger to such shareholder.

WesBanco and First Sentry have structured the merger to qualify as a reorganization within the meaning of Section 368(a) of the Code. The merger is conditioned upon receipt at closing by First Sentry of a legal opinion from Bowles Rice LLP and upon receipt at closing by WesBanco of a legal opinion from K&L Gates LLP, in each case, dated the closing date of the merger, and to the effect that the merger will be treated as a “reorganization”

- 56 -

within the meaning of Section 368(a) of the Code. Neither of these opinions will be binding on the Internal Revenue Service (the “IRS”) or the courts, and neither First Sentry nor WesBanco intends to request a ruling from the IRS regarding the U.S. federal income tax consequences of the merger. Consequently, we cannot assure you that the IRS will not assert, or that a court would not sustain, a position contrary to any of those set forth below.

The opinions of K&L Gates LLP and Bowles Rice LLP to be issued at closing will rely on certain assumptions that customarily are made with respect to transactions of this kind. The opinions also will rely on representations and covenants, including certain factual representations contained in officers’ certificates of First Sentry and WesBanco. K&L Gates LLP and Bowles Rice LLP will assume such representations to be true, correct and complete. If any such representation cannot be made on the effective date of the merger, or any such representation or assumption upon which the opinions are based is inconsistent with the actual facts or incorrect, then K&L Gates LLP and Bowles Rice LLP may be unable to render the opinions upon which the closing is conditioned, and the U.S. federal income tax consequences of the merger could be adversely affected.

Receipt of WesBanco Common Stock

A shareholder of First Sentry common stock who, pursuant to the merger, receives only WesBanco common stock in exchange for First Sentry common stock will generally not recognize any gain or loss upon such exchange, except in respect of cash received in lieu of a fractional share of WesBanco common stock (as discussed below under “Cash Received in Lieu of a Fractional Share of WesBanco Common Stock”). The aggregate adjusted tax basis of WesBanco common stock received in the merger (including fractional shares deemed received and redeemed as described below) will equal the aggregate adjusted tax basis of the First Sentry common stock surrendered therefor, decreased by the amount of any tax basis allocable to any fractional share interest in WesBanco common stock for which cash is received.The holding period of WesBanco common stock received in the merger will include the holding period of the shares of First Sentry common stock surrendered in the merger.

Cash Received in Lieu of a Fractional Share of WesBanco Common Stock

A shareholder of First Sentry common stock who receives cash instead of a fractional share of WesBanco common stock will generally be treated as having received such fractional share and then as having received such cash in redemption of that fractional share by WesBanco. A First Sentry shareholder who receives cash in lieu of a fractional share of WesBanco common stock and who does not otherwise hold shares of WesBanco common stock generally will recognize gain or loss equal to the difference between the amount of cash received and the First Sentry shareholder’s portion of such shareholder’s aggregate adjusted tax basis of the shares of First Sentry common stock exchanged in the merger which is allocable to such fractional share. Such gain or loss will be long-term capital gain or loss if, as of the effective date of the merger, the holding period for such shares is more than one year. The deductibility of capital losses is subject to limitations. First Sentry shareholders who separately hold shares of WesBanco common stock should consult their own tax advisors concerning the treatment of cash received for a fractional share.

Cash Received on Exercise of Dissenters’ Rights

A shareholder of First Sentry common stock that receives cash in exchange for such shareholder’s First Sentry common stock upon exercise of dissenters’ rights will recognize gain or loss equal to the difference between the amount of cash received and the shareholder’s adjusted tax basis in the First Sentry common stock exchanged therefor. Each shareholder of First Sentry common stock is urged to consult such shareholder’s tax advisor regarding the manner in which gain or loss should be calculated among different blocks of First Sentry common stock exchanged in the merger. Such gain or loss will generally be long-term or short-term capital gain or loss, depending on the shareholder’s holding period in the First Sentry common stock exchanged. The tax consequences of cash received may vary depending upon a shareholder’s individual circumstances. Each shareholder of First Sentry common stock who contemplates exercising statutory dissenters’ rights should

- 57 -

consult its tax adviser as to the possibility that all or a portion of the payment received pursuant to the exercise of such rights will be treated as dividend income.

Backup Withholding and Information Reporting

Anon-corporate shareholder may be subject to backup withholding (currently at a rate of 28%) on any cash received in the merger, including cash received in lieu of a fractional WesBanco common stock share. Backup withholding generally will not apply, however, to such shareholders that:

• furnish a correct taxpayer identification number, certify that they are not subject to backup withholding on an IRS FormW-9 or successor form and otherwise comply with all the applicable requirements of the backup withholding rules; or

• provide proof that they are otherwise exempt from backup withholding.

Any amounts withheld under the backup withholding rules will generally be allowed as a refund or credit against the shareholder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

A shareholder of First Sentry common stock who receives WesBanco common stock as a result of the merger will be required to retain records pertaining to the merger and make such records available to any authorized IRS officers and employees. The records should include the number of shares of First Sentry stock exchanged, the number of shares of WesBanco stock received, the fair market value and tax basis of First Sentry shares exchanged and the shareholder’s tax basis in the WesBanco common stock received. Each shareholder of First Sentry common stock that is required to file a U.S. federal income tax return and who is a “significant holder” that receives WesBanco common stock in the merger will be required to file a statement with the shareholder’s U.S. federal income tax return for the year of the merger in accordance with Treasury RegulationSection 1.368-3 setting forth the names and employer identification numbers of First Sentry and WesBanco, the date of the merger, such shareholder’s basis in the First Sentry common stock surrendered (determined immediately prior to the exchange) and the fair market value of the First Sentry common stock which is exchanged by that significant holder (determined immediately prior to the exchange) and entitled “STATEMENT PURSUANT TO§1.368-3 BY [INSERT NAME AND TAXPAYER IDENTIFICATION NUMBER (IF ANY) OF TAXPAYER], A SIGNIFICANT HOLDER”. A “significant holder” is a shareholder of First Sentry common stock that, immediately before the merger, owned at least 5% of the outstanding stock of First Sentry or securities of First Sentry with a basis for U.S. federal income taxes of at least $1.0 million.

The foregoing discussion is intended only as a summary and does not purport to be a complete analysis of all potential U.S. federal income tax consequences of the merger. You are urged to consult your tax advisor concerning the U.S. federal, state, local and foreign tax consequences of the merger to your particular situation.

- 64 -

In addition to the conditions discussed above, WesBanco’s obligation to consummate the merger is conditioned upon (i) the receipt of all consents and approvals required to be obtained by WesBanco, (ii) the aggregate amount of certain specified First Sentry loans must be less than the amount agreed upon by WesBanco and First Sentry in the merger agreement and (iii) shareholders holding not more than 10% of the outstanding shares of First Sentry common stock shall have exercised dissenters’ rights under West Virginia law.

Termination of the Merger Agreement

The merger agreement may be terminated at any time prior to the closing of the merger:

• by mutual written consent of First Sentry and WesBanco;

• by either WesBanco or First Sentry if the other party has breached any of its representations or warranties in a manner that would have a material adverse effect or if the other party has materially failed to comply with any of its covenants or agreements under the merger agreement and which breach ornon-compliance is not cured within thirty calendar days of notice thereof;

• by either WesBanco or First Sentry if the merger has not closed by September 30, 2018, and such failure to close is not caused by a breach of the merger agreement by the terminating party;

• by either WesBanco or First Sentry if the First Sentry shareholders do not approve the merger agreement;

• by either WesBanco or First Sentry if the governmental approvals required to consummate the merger are denied by a finalnon-appealable action; or

WesBanco may terminate the merger agreement:

• if First Sentry’s board of directors:

(A) modifies, qualifies, withholds or withdraws its recommendation to First Sentry shareholders that they should approve the merger agreement, or makes any statement, filing or release, in connection with the special meeting of First Sentry shareholders or otherwise, which is inconsistent with the recommendation of First Sentry’s board of directors that First Sentry shareholders approve the merger agreement,

(B) breaches its obligations to call, give notice of and commence the special meeting of First Sentry shareholders,

(C) approves or recommends an Acquisition Proposal (as defined below on page 68),

(D) fails to publicly recommend against a publicly announced Acquisition Proposal within ten business days of being requested to do so by WesBanco,

(E) fails to publicly reconfirm its recommendation to the First Sentry shareholders that they approve the merger agreement within ten business days of being requested to do so by WesBanco, or resolves or otherwise determines to take, or announces an intention to take, any of the actions listed in the preceding paragraphs; or

• if there will have been a material breach of First Sentry’s covenant not to solicit competing offers.

In addition, First Sentry may terminate the merger agreement:

• in order to enter into an agreement with respect to an unsolicited proposal that if consummated would be reasonably likely to result in a transaction more favorable to First Sentry’s shareholders from a financial point of view, provided that certain other terms and conditions contained in the merger agreement are also complied with, and First Sentry pays the termination fee described below; or

• if there is a substantial decline in WesBanco’s stock price that is not generally experienced by comparable banks, as described in detail below.

- 65 -

The operation of the conditions permitting First Sentry to terminate the merger agreement based on a decrease in the market price of the WesBanco common stock reflects the parties’ agreement that First Sentry shareholders will assume:

• the risk of a decline in value of the WesBanco common stock to $31.10 per share under any circumstances, and

• the risk of a more significant decline in value of WesBanco common stock unless the percentage decline from $38.88 to the average value of WesBanco common stock during the fifteen (15) consecutive trading day period ending on the Determination Date is more than 20% greater than the percentage decrease, if any, in the closing value of the Nasdaq Bank Index from November 9, 2017 to the Determination Date.

The purpose of this provision is that a decline in the value of WesBanco’s common stock which is comparable to the decline in the value of an index of comparable publicly-traded stocks is indicative of a broad-based change in market and economic conditions affecting the financial services industry generally rather than factors which affect the value of the WesBanco common stock in particular.

Specifically, First Sentry may terminate the merger agreement during thefive-day period (“Election Period”) beginning on the fifth trading day immediately preceding the later of (i) the first date on which all necessary bank regulatory approvals ornon-objections have been received (disregarding any waiting period) or (ii) the date on which the First Sentry’s shareholders approve the merger agreement (the “Determination Date”) if all of the following occur:

(i) the average daily closing price of a share of WesBanco common stock during the fifteen (15) consecutive trading days ending on the Determination Date (the “WesBanco Ending Price”) is less than $31.10; and

(ii) the quotient obtained by dividing the WesBanco Ending Price by $38.88 (the “WesBanco Starting Price”) is less than the difference obtained by subtracting 0.20 from the quotient obtained by dividing the closing value of the Nasdaq Bank Index on the Determination Date by 3,757.25, which was the closing value of the Nasdaq Bank Index on November 9, 2017 (the “Index Ratio”);

(iii) First Sentry notifies WesBanco in writing of First Sentry’s intention to terminate the merger agreement during the Election Period; and

(iv) WesBanco elects not to increase the exchange ratio in accordance with the formula described below within thefive-day period following its receipt of notice that First Sentry intends to so terminate the merger agreement.

Even if the first two conditions described above are met, the First Sentry board of directors may elect not to terminate the merger agreement. Any decision to terminate the merger agreement will be made by the First Sentry board of directors in light of all of the circumstances existing at the time. Prior to making any decision to terminate the merger agreement, the First Sentry board of directors would consult with its financial and other advisors and would consider all financial and other information it deemed relevant to its decision, including whether the then current consideration to be received in the merger would deliver more value to First Sentry shareholders than the value that could be expected if First Sentry were to continue as an independent company. In addition, the First Sentry board of directors would consider whether, in light of market and other industry conditions at the time of such decision, the exchange ratio continued to be fair from a financial point of view to First Sentry’s shareholders. If First Sentry elected not to terminate the merger agreement, which it could do without any action on the part of First Sentry shareholders, the exchange ratio of WesBanco common stock would remain 1.5869.

If each of the first two conditions set forth above were satisfied and the First Sentry board of directors elected to terminate the merger agreement, WesBanco would have the option of increasing the consideration

- 66 -

payable to First Sentry shareholders by adjusting the exchange ratio as described below. WesBanco is under no obligation to adjust the exchange ratio and there can be no assurance that WesBanco would elect to adjust the exchange ratio to prevent the termination of the merger agreement. Any decision would be made by WesBanco in light of the circumstances existing at the time. If WesBanco elected to adjust the exchange ratio, First Sentry could not terminate the merger agreement as a result of the above-described circumstances.

The operation and effect of the provisions of the merger agreement dealing with a decline in the market price of WesBanco’s common stock may be illustrated by the following three scenarios:

(1) One scenario is that the WesBanco Ending Price is above $31.10. In this event, First Sentry would not have the right to terminate the merger agreement pursuant to these provisions.

(2) A second scenario is that the WesBanco Ending Price is less than $31.10, but the percentage decline in the price of the WesBanco common stock from the initial measurement price of $38.88 is not more than 20% greater than the percentage decline in the closing value of the Nasdaq Bank Index. Under this scenario, First Sentry would not have the right to terminate the merger agreement.

(3) A third scenario is that the WesBanco Ending Price is less than $31.10 and the percentage decline in the price of WesBanco common stock from the initial measurement price is more than 20% greater than the decline in the closing value of the Nasdaq Bank Index. Under this scenario, First Sentry would have the right, but not the obligation, to terminate the merger agreement unless WesBanco elected to increase the exchange ratio to equal the number that is the greater of the number obtained by (A) dividing $64.00 by $31.10 or (B) dividing $64.00 by the product obtained by multiplying $38.88 by the Index Ratio.

If, between November 9, 2017 and the Determination Date, WesBanco declares or effects a stock dividend, reclassification, recapitalization,split-up, combination, exchange of shares or similar transaction, the prices for the common stock of WesBanco will be appropriately adjusted for purposes of the termination provision discussed above.

If either First Sentry or WesBanco terminates the merger agreement as provided above, all further obligations of First Sentry and WesBanco under the merger agreement, except with respect to specified matters, will terminate.

Expenses

Whether or not the merger is completed, each party will pay all legal and accounting fees and other costs and expenses it incurs in connection with the merger agreement and the transactions contemplated by the merger agreement. WesBanco will pay all governmental and regulatory authority fees incurred in connection with the transactions contemplated by the merger agreement.

Termination Fee

The merger agreement provides that First Sentry may be required to pay a termination fee to WesBanco of $3,000,000 in the following circumstances:

• If WesBanco terminates the merger agreement because First Sentry’s board of directors:

As defined in the merger agreement, “Acquisition Proposal” means any inquiry, offer or proposal (other than an inquiry offer or proposal from WesBanco), whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to, an Acquisition Transaction. An “Acquisition Transaction” means:

• any transaction or series of transactions involving any merger, consolidation, recapitalization, share exchange, liquidation, dissolution or similar transaction involving First Sentry or any of its subsidiaries;

• any transaction pursuant to which any third party or group acquires or would acquire (whether through sale, lease or other disposition), directly or indirectly, any assets of First Sentry or any of its subsidiaries representing, in the aggregate, 20% or more of the assets of First Sentry and its subsidiaries on a consolidated basis;

• any issuance, sale or other disposition of (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase or securities convertible into, such securities) representing 20% or more of the votes attached to the outstanding securities of First Sentry or any of its subsidiaries;

• any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning 20% or more of any class of equity securities of First Sentry or any of its subsidiaries; or

• any transaction that is similar in form, substance or purpose to one or more of the transactions listed in the preceding paragraphs.

Amendment or Waiver

The provisions of the merger agreement may be waived at any time by the party that is entitled to the benefit of those provisions, which requires action be taken by the board of directors of that party. Any of the terms of the merger agreement may be amended or modified in writing before the special meeting of the First Sentry shareholders. The merger agreement may be amended after the special meeting and prior to the closing of the merger only to the extent permitted by applicable laws and to the extent the amendment does not alter or change the amount or kind of the merger consideration to be received by First Sentry shareholders in the merger.

Effective Date of the Merger

We expect the merger to be completed as soon as practicable after all regulatory approvals and shareholder approvals have been received. We expect this to occur during the first half of 2018.

INFORMATION ABOUT FIRST SENTRY

First Sentry and First Sentry Bank, Inc.

In this section describing First Sentry and First Sentry Bank, Inc., the words “we” and “our” refer to First Sentry and/or First Sentry Bank, Inc.

In 2002, First Sentry became the bank holding company of First Sentry Bank, Inc. (“First Sentry Bank”). On September 25, 2009, we completed our merger with Guaranty Financial Services, Inc. and became an SEC reporting company. With passage of the JOBS Act in April 2012 increasing the threshold of the number of shareholders required for SEC registration, First Sentry was able to deregister with the SEC in the summer of 2012. We do not have any business activities other than our ownership of First Sentry Bank common stock and our two business trusts relating to trust preferred securities. As the holding company of First Sentry Bank, we are authorized to pursue other business activities permitted by applicable laws and regulations for bank holding companies. Our executive office is located at 823 Eighth Street, Huntington, West Virginia. Our telephone number is (304)522-6400. As of September 30, 2017, we had approximately $666 million in consolidated total assets, $527 million of total deposits, $455 million in total loans and $52 million of shareholders’ equity. We are subject to regulation by the Board of Governors of the Federal Reserve System, the FDIC and the West Virginia Division of Financial Institutions.

All of our officers and directors are also officers and directors of First Sentry Bank. In addition, we use the support staff of First Sentry Bank from time to time.

Our principal business consists of accepting deposits, originating commercial real estate loans, commercial loans,one- to four-family residential mortgage loans and, to a lesser extent, originating consumer loans. We also invest in investment securities. We operate from our main office in Huntington, West Virginia and four other branch offices located in Cabell, Lincoln and Putnam counties, West Virginia. Our retail banking offices consist of multiple delivery channels, including full-service banking offices, automated teller machines and telephone and internet banking capabilities. We consider our reputation for superior customer service and financial strength as our major strengths in attracting and retaining customers in our market areas.

We attract retail deposits from the general public in the communities surrounding our main office and our branch offices. We also accept brokered deposits as well as deposits via our participation in the CDARS, ICS and IND networks that are considered brokered deposits. A significant portion of our commercial real estate, residential real estate and commercial loans are generated by referrals from brokers, current customers, professional contacts and through a general marketing campaign. We generally retain in our portfolio all adjustable-rate loans we originate, as well as fixed-rate loans with terms of five years or less. For customers who are interested in longer term loans, such as traditional fixed rate 30 yearone- to four-family residential mortgage loans, we function as a conduit by acting as a mortgage broker with other financial institutions and receive a fee from the other financial institutions for this service. We have entered into limited loan participations in recent years.

Our revenues are derived primarily from interest on loans and investment securities, and to a lesser extent, cash and due from banks. We also generate revenues from fees and service charges. Our primary sources of funds are deposits, borrowings in the form of securities sold under agreements to repurchase and FHLB advances and principal and interest payments on securities and loans.

Indemnification of Officers and Directors
Under the WVBCA, a corporation is generally permitted to indemnify a director if the director conducted himself or herself in good faith, he or she reasonably believed the conduct to be in the best interests of the corporation (or, in all other cases, at least not opposed to the best interests of the corporation), and, in the case of any criminal proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful. In addition, the WVBCA permits a corporation to include broader indemnification in its articles of incorporation so long as the provision does not limit the liability for (i) receipt of a financial benefit to which he or she is not entitled, (ii) an intentional infliction of harm on the corporation or its shareholders, (iii) certain unlawful distributions, or (iv) an intentional violation of criminal law. The articles of incorporation may also contain a provision (the “elimination provision”) eliminating or limiting the personal liability of a director to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director so long as the provision does not eliminate or limit the liability of a director for (i) any breach of the director’s duty of loyalty to the corporation or its shareholders, (ii) acts or omissions not in good faith or which involve intentional misconduct of a knowing violation of law, (iii) certain unlawful distributions, or (iv) any transaction from which the director derived an improper personal benefit. The elimination provision may not apply to conduct occurring prior to the provision’s adoption. The WVBCA requires a corporation to indemnify a director, who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he or she was a party because he or she was a director of the corporation, against reasonable expenses incurred by him or her in connection with the proceeding. The WVBCA permits a corporation to advance funds to pay for or reimburse the reasonable expenses incurred	The provisions of the WVBCA discussed for WesBanco also apply to First Sentry and such discussion is incorporated herein. First Sentry’s articles of incorporation provide indemnification up to the fullest extent permitted under West Virginia law. In addition, the articles of incorporation provide that each current or former director, officer or agent of the corporation will be indemnified against costs or expenses in connection with any claim, action, suit or proceeding whether criminal or civil relating to service to the corporation, except in cases where the person was adjudged to be liable for gross negligence or willful misconduct in the performance of a duty to the corporation.

- 79 -

by a director, prior to the final disposition of a proceeding, who is a party to a proceeding because he or she is a director, if he or she delivers to the corporation:

•       a written affirmation of his or her good faith belief that he or she has met the relevant standard of conduct described in the first sentence of the preceding paragraph or that the proceeding involves conduct for which liability has been eliminated under the elimination provision; and

•       a written undertaking to repay any funds advanced if he or she is not entitled to mandatory indemnification and it is ultimately determined that he or she has not met the relevant standard of conduct.

The WVBCA provides that a corporation may indemnify its officers to the same extent as a director and, if the officer is not a director or if the officer is a party to the proceeding solely in his capacity as an officer, to a further extent as may be provided in the articles of incorporation, the bylaws, a resolution of the board of directors, or a contract, except that such additional indemnification may not be provided for liability in connection with a proceeding by or in the right of the corporation other than for reasonable expenses incurred in connection with the proceeding or liability arising out of conduct that constitutes (i) receipt by him or her of a financial benefit to which he or she is not entitled, (ii) an intentional infliction of harm on the corporation or the shareholders, or (iii) an intentional violation of criminal law. The WVBCA mandates indemnification of officers that are not directors to the same extent as directors.

WesBanco’s bylaws provide that WesBanco will indemnify each of its directors and officers, whether or not then in office, against all liability incurred in connection with any suit to which he is a party by reason of having been an officer or director of WesBanco or another company which he served at the request of WesBanco to the maximum extent permitted under the WVBCA

WesBanco bylaws provide that a director or officer cannot receive a “prohibited indemnification payment,” which is defined as any payment or agreement to make a payment or reimburse such director or officer for any liability or legal expenses in any administrative proceeding brought by the appropriate federal banking agency that results in a final order or settlement in

- 80 -

which the director or officer is assessed a civil monetary penalty, is removed or prohibited from conducting the business of banking, or is required to cease an action or take any affirmative action, including making restitution, with respect to WesBanco Bank, Inc. or WesBanco. Finally, WesBanco’s bylaws provide that a reasonable indemnification payment will be made only if all of the following conditions are met: (i) the board of directors investigates and determines in writing that the director or officer acted in good faith and in the best interest of WesBanco Bank, Inc. or WesBanco; (ii) the board of directors investigates and determines that the payment will not materially adversely affect the safety and soundness of WesBanco Bank, Inc. or WesBanco; (iii) the payment does not fall within the definition of a prohibited indemnification payment; and (iv) the director or officer agrees in writing to reimburse WesBanco, to the extent not covered by permissible insurance, for advanced indemnification payments that subsequently become prohibited indemnification payments. WesBanco’s bylaws provide that WesBanco may purchase commercial insurance to cover certain costs that WesBanco incurs under the indemnification provisions. Costs that may be covered include legal expenses and restitution that an individual may be ordered to make to WesBanco. Such insurance may not pay or reimburse a director or officer for any final judgment or civil money penalty assessed against such individual. Partial indemnification for legal expenses is permitted in connection with a settlement when there is a formal and final finding that the director or officer has not breached a fiduciary duty, engaged in unsafe or unsound practices, and is not subject to a final prohibition order.
Amendment of Articles of Incorporation
Pursuant to the WVBCA, the WesBanco articles of incorporation and bylaws may generally be amended by the affirmative vote of a majority of all votes of shareholders entitled to be cast on the matter amendment and a majority of the outstanding stock of each class entitled to vote on the amendment, unless a greater number is specified in the articles of incorporation. The WesBanco articles of incorporation provide that the affirmative vote of the holders of not less than 75% of the outstanding shares of the voting stock is required to amend, alter, change, or repeal the article section dealing with the classes of directors.	Pursuant to the WVBCA, the articles of incorporation of First Sentry may be amended by the affirmative vote of a majority of the votes cast by First Sentry shareholders at any meeting at which a quorum is present called for the purpose of amending the articles of incorporation.

- 81 -

Amendment of Bylaws

WesBanco’s bylaws require the affirmative vote of the holders of not less than 75% of the outstanding shares of the capital stock to amend or repeal the bylaw provisions dealing with the composition of the board of directors. The other bylaw provisions may be amended, altered, or repealed (i) at any duly called and constituted shareholders’ meeting on the affirmative vote of the majority of the stock represented at such meeting, or (ii) at any meeting of the board of directors upon the affirmative vote of the majority of the whole of the board, provided that each member of the board of directors is served with written notice of the proposed amendment at least two days in advance of such meeting.

The First Sentry board of directors shall have the power and authority to alter, amend or repeal the bylaws by the vote of a majority of the entire board of directors, subject always to the power of the shareholders to change or repeal such bylaws set forth in the WVBCA.

PROPOSAL NO. 2 —

ADJOURNMENT PROPOSAL

The Adjournment Proposal

If a quorum is present at the First Sentry special meeting but there are insufficient votes to approve the merger agreement, the merger proposal will fail unless First Sentry adjourns the First Sentry special meeting in order to solicit additional proxies from First Sentry’s shareholders. An adjournment under such circumstances will allow First Sentry extra time to solicit additional proxies. In order to allow shares present in person or by proxy at the First Sentry special meeting to vote FOR approval of the adjournment of the First Sentry special meeting, if necessary, First Sentry is submitting a proposal to adjourn the First Sentry special meeting to First Sentry shareholders as a separate matter for consideration. First Sentry will vote properly submitted proxy cards“FOR” approval of the First Sentry adjournment proposal, unless otherwise instructed on the proxy. If First Sentry shareholders approve the First Sentry adjournment proposal, First Sentry is not required to give any further notice of the time and place of the adjourned First Sentry meeting other than an announcement of the time and place to be provided at the First Sentry special meeting.

If a quorum is not present at the meeting, the meeting will be adjourned to a later time without a vote.

Recommendation of First Sentry’s Board of Directors

First Sentry’s board of directors recommends that First Sentry shareholders vote “FOR” the proposal to approve of the adjournment of the First Sentry special meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the First Sentry special meeting to approve the proposal to approve the merger agreement.

(d) Lost, Stolen or Destroyed Certificates.If there shall be delivered to the Exchange Agent by any person who is unable to produce any Seller Certificate for Seller Shares for surrender to the Exchange Agent in accordance with this Section 2.03:

(i) evidence to the reasonable satisfaction of the Surviving Corporation that such Seller Certificate has been lost, wrongfully taken, or destroyed;

(ii) such security or indemnity as reasonably may be requested by the Surviving Corporation to save it harmless (which may include the requirement to obtain a third party bond or surety); and

(iii) evidence, to the reasonable satisfaction of the Surviving Corporation, that such person was the owner of the Seller Shares theretofore represented by each such Seller Certificate claimed by him to be lost, wrongfully taken or destroyed and that he is the person who would be entitled to present such Seller Certificate for exchange pursuant to this Agreement;

then the Exchange Agent, in the absence of actual notice to it that any Seller Shares theretofore represented by any such Seller Certificate have been acquired by a bona fide purchaser, shall deliver to such person (a) the Merger Consideration for each Seller Share represented by the lost, stolen or destroyed Seller Certificate, (b) any cash in lieu of fractional shares into which the Seller Shares represented by the Seller Certificate have been converted, (c) any other dividend or distribution with a record date after the Effective Time theretofore paid with respect to Buyer Shares issuable in the Merger, and (d) subject to compliance with Section 7.08, any dividend or distribution with respect to Seller Shares with a record date prior to the Effective Time, in each case without interest, that such person would have been entitled to receive upon surrender of each such lost, wrongfully taken or destroyed Seller Certificate.

(e) No Further Ownership Rights in Seller Shares. All cash and Buyer Shares issued upon conversion of Seller Shares in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such Seller Shares; subject, however, to the Surviving Corporation’s obligation to pay any dividends or make any other distributions with a record date prior to the Effective Time that may have been declared or made by Seller (but only in compliance with the terms of this Agreement) on such Seller Shares prior to the Effective Time and which remain unpaid at the Effective Time, subject to compliance with Section 7.08.

(f) No Fractional Buyer Shares.

(i) No certificates or scrip representing fractional Buyer Shares shall be issued upon the surrender for exchange of Seller Certificates evidencing Seller Shares, and such fractional Buyer Share interests will not entitle the owner thereof to vote or to any rights of a shareholder of the Surviving Corporation.

(ii) Each holder of Seller Shares who would otherwise be entitled to receive a fractional Buyer Share shall instead receive from the Exchange Agent an amount of cash, without interest, equal to the product obtained by multiplying (a) the fractional Buyer Share (rounded to the nearest thousandth when expressed in decimal form) interest to which such holder (after taking into account all Seller

A-6

Shares held at the Effective Time by such holder) would otherwise be entitled by (b) the Average Closing Price (as defined in Section 11.01(d)(iv)).

(g) Termination of Exchange Fund. Any portion of the Exchange Fund delivered to the Exchange Agent by Buyer pursuant to Section 2.03(b) that remains undistributed to the shareholders of Seller for 12 months after the Effective Time may be delivered to the Surviving Corporation, upon Buyer’s demand, and any shareholders of Seller who have not theretofore complied with this Article Two shall thereafter look only to the Surviving Corporation for payment of the Merger Consideration, any cash in lieu of fractional Buyer Share interest and any dividends or distributions with respect to Buyer Shares issuable in the Merger, in each case without interest.

(h) No Liability. None of Buyer, Seller, the Exchange Agent or the Surviving Corporation shall be liable to any former holder of Seller Shares for any payment of the Merger Consideration, any cash in lieu of fractional Buyer Share interest or any dividends or distributions with respect to Buyer Shares issuable in the Merger delivered to a public official as and if required by any applicable abandoned property, escheat or similar law.

(i) Withholding Rights. Buyer or the Exchange Agent shall be entitled to deduct and withhold from any cash consideration otherwise payable pursuant to this Agreement to any holder of Seller Certificates such amounts as Buyer or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code, or any other provision of domestic or foreign (whether national, federal, state, provincial, local or otherwise) tax law. To the extent that amounts are properly withheld and paid over to the appropriate taxing authority by Buyer or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Seller Certificates in respect of which such deduction and withholding was made by Buyer, the Surviving Corporation or the Exchange Agent.

(j) Waiver.The Surviving Corporation may from time to time, in the case of one or more persons, waive one or more of the rights provided to it in this Article Two to withhold certain payments, deliveries and distributions; and no such waiver shall constitute a waiver of its rights thereafter to withhold any such payment, delivery or distribution in the case of any person.

2.04.    Seller Shareholders’ Dissenters’ Rights

Anything contained in this Agreement or elsewhere to the contrary notwithstanding, if any holder of an outstanding Seller Share who is entitled to demand and properly demands payment of the fair value of such Seller Share in accordance with Chapter 31D, Article 13 of the WVBCA (a “Seller Dissenting Share”), then such Seller Dissenting Share shall not be converted into the right to receive the Merger Consideration, and instead:

(a) Each such Seller Dissenting Share shall nevertheless be deemed to be extinguished at the Effective Time as provided elsewhere in this Agreement;

(b) Each holder perfecting such dissenters’ rights shall thereafter have only such rights (and shall have such obligations) as are provided in Chapter 31D, Article 13 of the WVBCA;provided, however, that if any such person shall have failed to perfect or shall withdraw or lose such holder’s rights under Chapter 31D, Article 13 of the WVBCA, each such holder’s Seller Dissenting Share shall thereupon be deemed to have been converted as of the Effective Time into the right to receive the Merger Consideration, without any interest thereon.

No holder of a Seller Dissenting Share shall be entitled to submit a letter of transmittal, and any letter of transmittal submitted by a holder of a Seller Dissenting Share shall be invalid, unless and until the demand for the payment of the fair value made in respect of such Seller Dissenting Share shall have been or is deemed to have been withdrawn.

2.05.    Anti-Dilution Provisions

In the event that, subsequent to the date of this Agreement but prior to the Effective Time, the outstanding Buyer Shares are increased, decreased, changed into or exchanged for a different number or kind of shares or securities (or Buyer establishes a record date for effecting any such change to the outstanding Buyer Shares) as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar changes in Buyer’s capitalization, excluding an acquisition by Buyer involving an exchange of Buyer Shares not resulting in a recapitalization of Buyer, appropriate and proportionate adjustment shall be made to the Merger Consideration. Nothing contained herein shall be deemed to permit any action that may be proscribed by this Agreement.

2.06.    Conversion of Seller Sub Capital Stock

Immediately after the Effective Time, each issued and outstanding share, and each share held in the treasury, of capital stock of Seller Sub shall, by virtue of the Bank Merger and without any action on the part of Buyer, Buyer Sub, Seller, Seller Sub or the holder thereof, be canceled without any conversion or issuance of any shares of capital stock of Buyer or Buyer Sub with respect thereto. No shares of Buyer or Buyer Sub shall be issued or exchanged and no consideration shall be given for shares of Seller Sub, and each then-issued and outstanding share, and each share then held in the treasury, of capital stock of Buyer Sub shall, by virtue of the Bank Merger and without any action on the part of Buyer, Buyer Sub, Seller, Seller Sub or the holder thereof, continue as one share of capital stock of the Surviving Bank Corporation having the same designations, preferences, limitations, and rights as such share of capital stock of Buyer Sub immediately prior to the Bank Merger.

Except as set forth in Section 3.01(i) of the Seller Disclosure Schedule, since the Seller Balance Sheet Date, there has not been any material adverse change in the business, operations, assets or financial condition of Seller and the Seller Subsidiaries taken as a whole, and, to the actual knowledge of Seller, no fact or condition exists that Seller believes will cause such a material adverse change in the future.

(j) Loan Documentation. The documentation (“Loan Documentation”) governing or relating to the material loan and credit-related assets (“Loan Assets”) included in the loan portfolio of the Seller Subsidiaries is legally sufficient for the purposes intended thereby and creates enforceable rights of the Seller Subsidiaries in accordance in all material respects with the terms of such Loan Documentation, subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and other similar laws relating to or affecting the enforcement of creditors’ rights generally, by general equitable principles (regardless of whether enforceability is considered in a proceeding in equity or at law) and by an implied covenant of good faith and fair dealing, except for such insufficiencies as would not have a material adverse effect on Seller. Except as set forth in Section 3.01(j) of the Seller Disclosure Schedule, no debtor under any of the Loan Documentation has asserted as of the date hereof any claim or defense with respect to the subject matter thereof, which claim or defense, if determined adversely to Seller, would have a material adverse effect on Seller. All loans and extensions of credit that have been made by the Seller Subsidiaries comply in all material respects with applicable regulatory limitations and procedures.

(k) Loans; Nonperforming and Classified Assets.

(i) To Seller’s knowledge, except as would not reasonably be expected to have a material adverse effect on Seller, each loan agreement, note or borrowing arrangement, including, without limitation, portions of outstanding lines of credit, loan commitments and loan guaranties (collectively,“Loans”), on Seller’s or any Seller Subsidiary’s books and records, was made and has been serviced in accordance with Seller’s lending standards in the ordinary course of business; is evidenced by appropriate and sufficient documentation; to the extent secured, has been secured by valid liens and security interests that have been perfected; and constitutes the legal, valid and binding obligation of the obligor named therein, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and other similar laws relating to or affecting the enforcement of creditors’ rights generally, and by general equitable principles (regardless of whether enforceability is considered in a proceeding in equity or at law). Seller has previously made available to Buyer complete and correct copies of its and the Seller Subsidiaries’ lending policies. The deposit and loan agreements of Seller and each Seller Subsidiary comply in all material respects with all applicable laws, rules and regulations. The allowance for loan and lease losses (“ALLL”) reflected in the Seller Financial Statements was, as of the date of each of the Seller Financial Statements, in the opinion of management of Seller, in compliance with Seller’s existing methodology for determining the adequacy of its ALLL and in compliance in all material respects with the standards established by the applicable Regulatory Authorities, the Financial Accounting Standards Board and GAAP, and is adequate.

All Loans that are classified as“Insider Transactions” by Regulation O of the Board of Governors of the Federal Reserve System (“Federal Reserve”) have been made by Seller or any of the Seller Subsidiaries in an arms-length manner made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons and do not involve more than normal risk of collectability or present other unfavorable features.

Seller and the Seller Subsidiaries have filed all reports and maintained all records required to be filed or maintained by them under the rules and regulations of the Federal Reserve, the WVDFI, the FDIC, the Federal Home Loan Bank of Pittsburgh (the “FHLB”) and any other applicable Regulatory Authorities, except for such reports and records the failure to file or maintain would not have a material adverse effect on Seller. All such documents and reports complied in all material respects with applicable requirements of law and rules and regulations in effect at the time such documents and reports were filed and contained in all material respects the information required to be stated therein, except for such documents and records the failure to comply with such laws, rules and regulations or contain such information would not reasonably be expected to have a material adverse effect on Seller. None of such documents or reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, other than such reports and documents which the failure to file in such fashion would not reasonably be expected to have a material adverse effect on Seller. There is no material unresolved violation, criticism or exception by any Governmental Authority or Regulatory Authority with respect to any report or letter relating to any examinations of Seller or any of the Seller Subsidiaries.

(m) Taxes. Except as set forth in Section 3.01(m) of the Seller Disclosure Schedule, Seller and the Seller Subsidiaries have timely filed (including all applicable extensions) all material returns, statements, reports and forms (including elections, declarations, disclosures, schedules, estimates and information returns) (collectively, the “Tax Returns”) with respect to all material federal, state, local and foreign income, gross income, gross receipts, gains, premium, sales, use,ad valorem, transfer, franchise, profits, withholding, payroll, employment, excise, severance, stamp, occupancy, license, lease, environmental, customs, duties, property, windfall profits and other taxes (including any interest, penalties or additions to tax with respect thereto, individually, a “Tax” and, collectively, “Taxes”) required to be filed with the appropriate tax authority through the date of this Agreement. Such Tax Returns, as amended, are true, correct and complete in all material respects. Seller and the Seller Subsidiaries have paid and discharged all Taxes shown as due on such Tax Returns, other than such Taxes that are adequately reserved as shown on the Seller Financial Statements or have arisen in the ordinary course of business since the Seller Balance Sheet Date.

There are no unexpired waivers by Seller or any Seller Subsidiary of any statute of limitations with respect to Taxes. The accruals and reserves for Taxes reflected in the Seller Financial Statements are adequate in all material respects for the periods covered. Seller and the Seller Subsidiaries have withheld or collected and paid over to the appropriate Governmental Authorities or are properly holding for such payment all Taxes required by law to be withheld or collected, except for such failures to withhold or collect as would not reasonably be expected to have a material adverse effect on Seller. There are no liens for Taxes upon the assets of Seller or any Seller Subsidiary, other than liens for current Taxes not yet due and payable and liens that, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on Seller. Neither Seller nor any Seller Subsidiary has agreed to make, or is required to make, any adjustment under Section 481(a) of

A-14

the Code. Except as set forth in Section 3.01(m) of the Seller Disclosure Schedule, neither Seller nor any Seller Subsidiary is a party to any agreement, contract, arrangement or plan that has resulted, or could result, individually or in the aggregate, in the payment of “excess parachute payments” within the meaning of Section 280G of the Code.

The Seller Real Properties constitute all of the material real property and interests in real property used in the businesses of Seller and the Seller Subsidiaries. Copies of all leases of Seller Real Properties to which Seller or any Seller Subsidiary is a party have been provided to Buyer. Except as set forth on Section 3.01(n) of the Seller Disclosure Schedule, the leasehold interests subject to such leases have not been assigned or subleased.

Notwithstanding the foregoing, the term “Seller Compensation and Benefit Plans” shall not include plans, funds, programs, policies, practices or procedures that are maintained or funded either (A) by Seller Employees, Seller Consultants, Seller Officers or Seller Directors for their own benefit or for the benefit of their employees, such as individual retirement arrangements or plans described in Section 401(a) of the Code benefiting (or intended to benefit) themselves or persons who are not Seller Employees or (B) by persons or entities who are not Seller ERISA Affiliates (as defined below).Neither Seller nor any Seller Subsidiary has any commitment to create any additional Seller Compensation and Benefit Plan or to modify or change any existing Seller Compensation and Benefit Plan, except to the extent required by law and as otherwise contemplated by Section 6.02 of this Agreement.

(ii) Except in a manner that would not have a material adverse effect on Seller, each Seller Compensation and Benefit Plan has been operated and administered in accordance with its terms and with applicable law, including, but not limited to, ERISA, the Code, the Securities Act of 1933, as amended (“Securities Act”), the Securities Exchange Act of 1934, as amended (“Exchange Act”), the Age Discrimination in Employment Act of 1967 (the“Age Discrimination in Employment Act”), or any regulations or rules promulgated thereunder, and all filings, disclosures and notices required by ERISA, the Code, the Securities Act, the Exchange Act, the Age Discrimination in Employment Act and any other applicable law have been timely made. Each Seller Compensation and Benefit Plan which is an “employee pension benefit plan” within the meaning of Section 3(2) of ERISA (a “SellerPensionPlan”) and which is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter (including a determination that the related trust under such Seller Compensation and Benefit Plan is exempt from tax under Section 501(a) of the Code) from the IRS, or is in the form of a prototype or volume submitter plan that is the subject of a favorable opinion letter from the IRS upon which Seller is entitled to rely, and Seller is not aware of any circumstances likely to result in revocation of any such favorable determination letter or opinion letter.

There is no

A-17

material pending or, to the actual knowledge of Seller, threatened legal action, suit or claim relating to the Seller Compensation and Benefit Plans other than routine claims for benefits thereunder. Neither Seller nor any Seller Subsidiary has engaged in a transaction, or omitted to take any action, with respect to any Seller Compensation and Benefit Plan that would reasonably be expected to subject Seller or any Seller Subsidiary to a tax or penalty imposed by either Section 4975 of the Code or Section 502 of ERISA, assuming for purposes of Section 4975 of the Code that the taxable period of any such transaction expired as of the date hereof.

(iii) No liability (other than for payment of premiums to the Pension Benefit Guaranty Corporation (the “PBGC”) which have been made or will be made on a timely basis) under Title IV of ERISA has been or is expected to be incurred by Seller or any subsidiary of Seller with respect to any ongoing, frozen or terminated “single-employer plan,” within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by any of them, or any single-employer plan of any entity (a “SellerERISAAffiliate Plan”) which is considered one employer with Seller under Section 4001(a)(14) of ERISA or Section 414(b), (c) or (m) of the Code (a “SellerERISA Affiliate”). During the six years prior to the Effective Time, none of Seller, any Seller Subsidiary nor any Seller ERISA Affiliate has contributed, or has been obligated to contribute, to a multiemployer plan under Subtitle E of Title IV of ERISA (as defined in ERISA Sections 3(37)(A) and 4001(a)(3)). No notice of a “reportable event”, within the meaning of Section 4043 of ERISA, for which the30-day reporting requirement has not been waived, has been required to be filed for any Seller Compensation and Benefit Plan or by any Seller ERISA Affiliate Plan within the12-month period ending on the date hereof, and no such notice will be required to be filed as a result of the transactions contemplated by this Agreement. The PBGC has not instituted proceedings to terminate any Seller Pension Plan or Seller ERISA Affiliate Plan and, to Seller’s actual knowledge, no condition exists that presents a material risk that such proceedings will be instituted. There is no pending investigation or enforcement action by the PBGC, the Department of Labor (“DOL”), the IRS or any other Governmental Authority with respect to any Seller Compensation and Benefit Plan and, to Seller’s actual knowledge, no such investigation or action is threatened or anticipated. Under each Seller Pension Plan and Seller ERISA Affiliate Plan, as of the date of the most recent actuarial valuation performed prior to the date of this Agreement, the actuarially determined present value of all “benefit liabilities”, within the meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the actuarial assumptions contained in such actuarial valuation of such Seller Pension Plan or Seller ERISA Affiliate Plan), did not exceed the then current value of the assets of such Seller Pension Plan or Seller ERISA Affiliate Plan and since such date there has been neither an adverse change in the financial condition of such Seller Pension Plan or Seller ERISA Affiliate Plan nor any amendment or other change to such Seller Pension Plan or Seller ERISA Affiliate Plan that would increase the amount of benefits thereunder which reasonably could be expected to change such result and that, individually or in the aggregate, would have a material adverse effect on Seller.

(iv) All contributions required to be made under the terms of any Seller Compensation and Benefit Plan or Seller ERISA Affiliate Plan or any employee benefit arrangements under any collective bargaining agreement to which Seller or any Seller Subsidiary is a party have been timely made or have been reflected on the Seller Financial Statements. Neither any Seller Pension Plan nor any Seller ERISA Affiliate Plan has an “accumulated funding deficiency” (whether or not waived) within the meaning of Section 412 of the Code or Section 302 of ERISA, and all required payments to the PBGC with respect to each Seller Pension Plan or Seller ERISA Affiliate Plan have been made on or before their due dates. None of Seller, any Seller Subsidiary nor any Seller ERISA Affiliate (x) has provided, or would reasonably be expected to be required to provide, security to any Seller Pension Plan or to any Seller ERISA Affiliate Plan pursuant to Section 401(a)(29) of the Code, and (y) has taken any action, or omitted to take any action, that has resulted, or would reasonably be expected to result, in the imposition of a lien under

A-18

Section 412(n) of the Code or pursuant to ERISA that, individually or in the aggregate, would have a material adverse effect on Seller.

(v) Except as disclosed in Section 3.01(t)(v) of the Seller Disclosure Schedule, neither Seller nor any Seller Subsidiary has any obligations to provide retiree health benefits, life insurance or other retiree death benefits under any Seller Compensation and Benefit Plan, other than benefits mandated by Section 4980B of the Code or those derived from a Seller Pension Plan.

(viii) Except as disclosed on Section 3.01(t)(viii) of the Seller Disclosure Schedule, the consummation of the transactions contemplated by this Agreement would not, directly or indirectly (including, without limitation, as a result of any termination of employment prior to or following the Effective Time), reasonably be expected to (A) entitle any Seller Employee, Seller Consultant or Seller Director to any payment from Seller or any Seller Affiliate (including severance pay or similar compensation, other than severance pay or compensation as otherwise provided under Section 6.02(a)) or any increase in compensation, (B) result in the vesting or acceleration of any benefits under any Seller Compensation and Benefit Plan, or (C) result in any material increase in benefits payable under any Seller Compensation and Benefit Plan.

(ix) Except as disclosed on Section 3.01(t)(ix) of the Seller Disclosure Schedule, neither Seller nor any Seller Subsidiary maintains any compensation plans, programs or arrangements, the payments under which would not reasonably be expected to be deductible as a result of the limitations under Section 162(m) of the Code and the regulations issued thereunder.

(x) As a result, directly or indirectly, of the transactions contemplated by this Agreement (including, without limitation, as a result of any termination of employment prior to or following the Effective Time), except as disclosed on Section 3.01(t)(x) of the Seller Disclosure Schedule, none of Seller, Buyer or the Surviving Corporation, or any of their respective Subsidiaries, will be obligated to make a payment that would be characterized as an “excess parachute payment” to an individual who is a “disqualified individual” (as such terms are defined in Section 280G of the Code) of Seller on a consolidated basis, without regard to whether such payment is reasonable compensation for personal services performed or to be performed in the future.

(iv) Seller and the Seller Subsidiaries have been and are in compliance with any applicable provisions of the Sarbanes-Oxley Act of 2002 and the related rules and regulations promulgated thereunder (the “Sarbanes-Oxley Act”), except where suchnon-compliance would not have a material adverse effect on Seller.

A-31

Benefit Plans”). Neither Buyer nor any Buyer Subsidiary has any commitment to create any additional Buyer Compensation and Benefit Plan or to modify or change any existing Buyer Compensation and Benefit Plan, except to the extent required by law and as otherwise contemplated by Sections 6.02 and 7.02of this Agreement.

(ii) Except in a manner that would not reasonably be expected to have a material adverse effect on Buyer, each Buyer Compensation and Benefit Plan has been operated and administered in accordance with its terms and with applicable law, including, but not limited to, ERISA, the Code, the Securities Act, the Exchange Act, the Age Discrimination in Employment Act, or any regulations or rules promulgated thereunder, and all filings, disclosures and notices required by ERISA, the Code, the Securities Act, the Exchange Act, the Age Discrimination in Employment Act and any other applicable law have been timely made. Each Buyer Compensation and Benefit Plan which is an “employee pension benefit plan” within the meaning of Section 3(2) of ERISA (a “BuyerPension Plan”) and which is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter (including a determination that the related trust under such Buyer Compensation and Benefit Plan is exempt from tax under Section 401(a) of the Code) from the IRS and Buyer is not aware of any circumstances likely to result in revocation of any such favorable determination letter.

There is no material pending or, to the actual knowledge of Buyer, threatened legal action, suit or claim relating to the Buyer Compensation and Benefit Plans other than routine claims for benefits thereunder. Neither Buyer nor any Buyer Subsidiary has engaged in a transaction, or omitted to take any action, with respect to any Buyer Compensation and Benefit Plan that would reasonably be expected to subject Buyer or any Buyer Subsidiary to a tax or penalty imposed by either Section 4975 of the Code or Section 502 of ERISA, assuming for purposes of Section 4975 of the Code that the taxable period of any such transaction expired as of the date hereof.

(iii) No liability (other than for payment of premiums to the PBGC which have been made or will be made on a timely basis) under Title IV of ERISA has been or is expected to be incurred by Buyer or any subsidiary of Buyer with respect to any ongoing, frozen or terminated “single-employer plan,” within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by any of them, or any single-employer plan of any entity (a “BuyerERISA Affiliate Plan”) which is considered one employer with Buyer under Section 4001(a)(14) of ERISA or Section 414(b), (c) or (m) of the Code (a “BuyerERISA Affiliate”). None of Buyer, any Buyer Subsidiary or any Buyer ERISA Affiliate has contributed, or has been obligated to contribute, to amulti-employer plan under Subtitle E of Title IV of ERISA (as defined in ERISA Sections 3(37)(A) and 4001(a)(3)) at any time since September 26, 1980. No notice of a “reportable event”, within the meaning of Section 4043 of ERISA, for which the30-day reporting requirement has not been waived, has been required to be filed for any Buyer Compensation and Benefit Plan or by any Buyer ERISA Affiliate Plan within the12-month period ending on the date hereof, and no such notice will be required to be filed as a result of the transactions contemplated by this Agreement. The PBGC has not instituted proceedings to terminate any Buyer Pension Plan or Buyer ERISA Affiliate Plan and, to Buyer’s actual knowledge, no condition exists that presents a material risk that such proceedings will be instituted. There is no pending investigation or enforcement action by the PBGC, the DOL, the IRS or any other Governmental Authority with respect to any Buyer Compensation and Benefit Plan, and to Buyer’s actual knowledge, no investigation or action is threatened or anticipated. Except as disclosed in Section 4.01(s)(iii) of the Buyer Disclosure Schedule, under each Buyer Pension Plan and Buyer ERISA Affiliate Plan, as of the date of the most recent actuarial valuation performed prior to the date of this Agreement, the actuarially

A-32

determined present value of all “benefit liabilities”, within the meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the actuarial assumptions contained in such actuarial valuation of such Buyer Pension Plan or Buyer ERISA Affiliate Plan), did not exceed the then current value of the assets of such Buyer Pension Plan or Buyer ERISA Affiliate Plan and since such date there has been neither an adverse change in the financial condition of such Buyer Pension Plan or Buyer ERISA Affiliate Plan nor any amendment or other change to such Buyer Pension Plan or Buyer ERISA Affiliate Plan that would increase the amount of benefits thereunder which reasonably could be expected to change such result and that, individually or in the aggregate, would have a material adverse effect on Buyer.

(iv) All contributions required to be made under the terms of any Buyer Compensation and Benefit Plan or Buyer ERISA Affiliate Plan or any employee benefit arrangements under any collective bargaining agreement to which Buyer or any Buyer Subsidiary is a party have been timely made or have been reflected on the Buyer Financial Statements.

None of Buyer, any Buyer Subsidiary nor any Buyer ERISA Affiliate (x) has provided, or would reasonably be expected to be required to provide, security to any Buyer Pension Plan or to any Buyer ERISA Affiliate Plan pursuant to Section 401(a)(29) of the Code, and (y) has taken any action, or omitted to take any action, that has resulted, or would reasonably be expected to result, in the imposition of a lien under Section 412(n) of the Code or pursuant to ERISA that, individually or in the aggregate, would have a material adverse effect on Buyer.

(v) Except as disclosed in Section 4.01(t)(v) of the Buyer Disclosure Schedule, neither Buyer nor any Buyer Subsidiary has any obligations to provide retiree health and life insurance or other retiree death benefits under any Buyer Compensation and Benefit Plan, other than benefits mandated by Section 4980B of the Code.

(a) Seller shall not and shall cause Seller Sub and the respective officers, directors, employees, investment bankers, financial advisors, attorneys, accountants, consultants, affiliates and other agents of Seller and Seller Sub (collectively, the “Seller Representatives”) not to, directly or indirectly, (i) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal (as defined below); (ii) participate in any discussions or negotiations regarding any Acquisition Proposal or furnish, or otherwise afford access, to any person (other than Buyer) any information or data with respect to Seller or the Seller Subsidiaries or otherwise relating to an Acquisition Proposal; (iii) release any person from, waive any provisions of, or fail to enforce any confidentiality agreement or standstill agreement to which Seller is a party; (iv) enter into any agreement, agreement in principle or letter of intent with respect to any Acquisition Proposal or approve or resolve to approve any Acquisition Proposal or any agreement, agreement in principle or letter of intent relating to an Acquisition Proposal; or (v) take any action to render the provisions of any Takeover Laws inapplicable to any person (other than Buyer or the Buyer Subsidiaries) or group in connection with any Acquisition Proposal. Any violation of the foregoing restrictions by any of the Seller Representatives, whether or not such Seller Representative is so authorized and whether or not such Seller Representative is purporting to act on behalf of Seller or otherwise, shall be deemed to be a breach of this Agreement by Seller. Seller and Seller Sub shall, and shall cause the Seller Representatives to, immediately cease and cause to be terminated all existing discussions, conversations, negotiations and other communications with any person conducted heretofore with respect to any of the foregoing.

For purposes of this Agreement,“Acquisition Proposal” shall mean any inquiry, offer or proposal (other than an inquiry, offer or proposal from Buyer), whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to, an Acquisition Transaction.

(b) Notwithstanding the provisions of Section 5.03(a), Seller may take any of the actions described in clause (ii) of Section 5.03(a) if, but only if, (i) Seller has received a bona fide unsolicited written Acquisition Proposal that did not result from a breach of this Section 5.03; (ii) Seller’s Board of Directors (the“Seller Board”) determines in good faith, after consultation with and having considered the advice of its outside legal counsel, that failure to take such actions would violate its fiduciary duties under applicable West Virginia law; (iii) Seller has provided Buyer with at least two (2) business days prior notice of such determination; and (iv) prior to furnishing or affording access to any information or data with respect to Seller or the Seller Subsidiaries or otherwise relating to an Acquisition Proposal, Seller receives from such person a confidentiality agreement with terms no less favorable to Seller than those contained in the confidentiality agreement between Seller and Buyer. Seller shall promptly provide to Buyer anynon-public information regarding Seller or the Seller Subsidiaries provided to any other person which was not previously provided to Buyer, such additional information to be provided no later than the date of provision of such information to such other party.

A-41

(c) Seller shall promptly (and in any event within twenty-four (24) hours) notify Buyer in writing if any proposals or offers are received by, any information is requested from, or any negotiations or discussions are sought to be initiated or continued with, Seller or the Seller Representatives, in each case in connection with any Acquisition Proposal, and such notice shall indicate the name of the person initiating such discussions or negotiations or making such proposal, offer or information request and the material terms and conditions of any proposals or offers (and, in the case of written materials relating to such proposal, offer, information request, negotiations or discussion, such notice shall include copies of such materials (includinge-mails or other electronic communications) unless (i) such materials constitute confidential information of the party making such offer or proposal under an effective confidentiality agreement, (ii) disclosure of such materials jeopardizes the attorney-client privilege or (iii) disclosure of such materials contravenes any law, rule, regulation, order, judgment or decree). Seller shall keep Buyer informed, on a current basis, of the status and terms of any such proposal, offer, information request, negotiations or discussions (including any amendments or modifications to such proposal, offer or request).

(d) Neither the Seller Board nor any committee thereof shall (i) withdraw, withhold, qualify or modify, or propose to withdraw, withhold, qualify or modify, in a manner adverse to Buyer in connection with the transactions contemplated by this Agreement (including the Merger and the Bank Merger), the Seller Board Recommendation (as defined in Section 7.06(f)), or make any statement, filing or release, in connection with the Seller Meeting (as defined in Section 7.06(e)) or otherwise, inconsistent with the Seller Board Recommendation (it being understood that taking a neutral position or no position with respect to an Acquisition Proposal shall be considered an adverse modification of the Seller Board Recommendation); (ii) approve or recommend, or propose to approve or recommend, any Acquisition Proposal; or (iii) enter into (or cause Seller or the Seller Subsidiaries to enter into) any letter of intent, agreement in principle, acquisition agreement or other agreement (A) related to any Acquisition Transaction or (B) requiring Seller to abandon, terminate or fail to consummate the Merger, the Bank Merger or any other transaction contemplated by this Agreement.

(e) Notwithstanding the provisions of Section 5.03(d), prior to the date of the Seller Meeting (as defined in Section 7.06(e)), the Seller Board may approve or recommend to the shareholders of Seller a Superior Proposal (as defined below) and withdraw, qualify or modify the Seller Board Recommendation in connection therewith (a“Seller Subsequent Determination”) after the third business day following Buyer’s receipt of a notice (the“Notice of Superior Proposal”) from Seller advising Buyer that the Seller Board has decided that a bona fide unsolicited written Acquisition Proposal that it received (that did not result from a breach of this Section 5.03) constitutes a Superior Proposal (it being understood that Seller shall be required to deliver a new Notice of Superior Proposal in respect of any revised Superior Proposal from such third party or its affiliates that Seller proposes to accept) if, but only if, (i) the Seller Board has reasonably determined in good faith, after consultation with and having considered the advice of outside legal counsel, that failure to take such actions would violate its fiduciary duties under applicable West Virginia law, (ii) during the three (3) business day period after receipt of the Notice of Superior Proposal by Buyer, Seller and the Seller Board shall have cooperated and negotiated in good faith with Buyer and give due consideration to such adjustments, modifications or amendments to the terms and conditions of this Agreement as may be proposed by Buyer in making a determination whether Seller will proceed with the Seller Board Recommendation without a Seller Subsequent Determination;provided,however, that neither Buyer nor Seller shall have any obligation to propose any adjustments, modifications or amendments to the terms and conditions of this Agreement, and (iii) at the end of such three (3) business day period, after taking into account any such adjusted, modified or amended terms as may have been proposed by Buyer since its receipt of such Notice of Superior Proposal, the Seller Board has again in good faith made the determination (A) in clause (i) of this Section 5.03(e) and (B) that such Acquisition Proposal constitutes a Superior Proposal. Notwithstanding the foregoing, the changing, qualifying or modifying of the Seller Board Recommendation or the making of a Seller Subsequent Determination by the Seller Board shall not change the approval of the Seller Board for purposes of causing any Takeover Laws to be inapplicable to this Agreement and the Voting Agreements and the transactions contemplated hereby and thereby, including the Merger and the Bank Merger.

A-42

For purposes of this Agreement,“Superior Proposal” shall mean any bona fide written proposal (on its most recently amended or modified terms, if amended or modified) made by a third party to enter into an Acquisition Transaction on terms that the Seller Board determines in its good faith judgment, after consultation with and having considered the advice of outside legal counsel and Seller’s Financial Advisor (i) would, if consummated, result in the acquisition of all, but not less than all, of the issued and outstanding shares of Seller common stock or all, or substantially all, of the assets of Seller and the Seller Subsidiaries on a consolidated basis; (ii) would result in a transaction that (A) involves consideration to the holders of the Seller Shares that is more favorable, from a financial point of view, than the consideration to be paid to Seller’s shareholders pursuant to this Agreement, considering, among other things, the nature of the consideration being offered and any material regulatory approvals or other risks associated with the timing of the proposed transaction beyond or in addition to those specifically contemplated hereby, and which proposal is not conditioned upon obtaining additional financing and (B) is, in light of the other terms of such proposal, more favorable to Seller’s shareholders than the Merger and the transactions contemplated by this Agreement; and (iii) is reasonably likely to be completed on the terms proposed, in each case taking into account all legal, financial, regulatory and other aspects of the proposal.

5.04.    Delivery of Information

Seller shall furnish to Buyer promptly after such documents are available: (a) all reports, proxy statements or other communications by Seller to its shareholders generally; and (b) all press releases relating to any transactions.

5.06.    No Control

Nothing contained in this Agreement shall give Buyer, directly or indirectly, the right to control or direct the operations of Seller or the Seller Subsidiaries prior to the Effective Time. Prior to the Effective Time, each of Seller and Buyer shall exercise, consistent with the terms of this Agreement, complete control and supervision over its and its subsidiaries respective operations.

In no event shall the Seller 401(k) Plan be merged with and into the Buyer 401(k) Plan, unless Buyer determines in its reasonable judgment that (A) the Seller 401(k) Plan is a qualified plan under Section 401(a) of the Code, both as to the form of the Seller 401(k) Plan and as to its operation, and (B) there are no facts in existence that would be reasonably likely to adversely affect the qualified status of the Seller 401(k) Plan.

A-43

If Buyer determines in its sole discretion not to merge the Seller 401(k) Plan into the Buyer 401(k) Plan and that the Seller 401(k) Plan should be terminated immediately prior to or at the Effective Time, Seller agrees to take all action necessary to have the Seller 401(k) Plan terminated immediately prior to or at the Effective Time;provided, that Buyer has delivered to Seller written notice of Buyer’s determination to terminate the Seller 401(k) Plan at least thirty (30) days prior to the Closing Date; andprovided,further, that Buyer agrees that prior to such termination, Seller is permitted to amend the Seller 401(k) Plan, to the extent permitted under applicable law and guidance, to allow the rollover in kind of any outstanding plan loans held in participant accounts. If Buyer determines that the Seller 401(k) Plan should be so terminated, the accounts of all participants and beneficiaries in the Seller 401(k) Plan as of such termination shall become fully vested upon termination of the Seller 401(k) Plan. As soon as practicable following the Effective Time, the account balances in the Seller 401(k) Plan shall be either distributed to participants and beneficiaries or rolled over to an eligibletax-qualified retirement plan or individual retirement account as a participant or beneficiary may direct in accordance with plan terms. Buyer agrees to permit Continuing Employees to rollover their account balances in the Seller 401(k) Plan to the Buyer 401(k) Plan, including thein-kind rollover of plan loans, which Buyer agrees in such event to administer according to their terms. Prior to taking any such action, Seller and Seller Sub shall provide Buyer with a copy of such resolutions or consent in connection with such Seller 401(k) Plan termination, and shall consider any comments provided by Buyer in good faith. Buyer shall indemnify Seller and the Seller Subsidiaries for any losses, fees, expenses and charges incurred by Seller in connection with the termination of the Seller 401(k) Plan if the Merger is not consummated in accordance with the terms of this Agreement.

(b)Other Benefit Plans. Immediately prior to the Effective Time and subject to the occurrence of the Effective Time, Seller and Seller Sub shall, at the request of Buyer, freeze or terminate each other Seller Compensation and Benefit Plan (other than written employment agreements) as requested by Buyer subject to and in accordance with applicable law and in accordance with plan requirements.

(d) In the event that this Agreement is terminated by Buyer pursuant to Sections 11.01(c)(i) or (ii) and (A) an Acquisition Proposal with respect to Seller shall have been publicly announced, disclosed or otherwise communicated to the Seller Board prior to any breach by Seller of any representation, warranty, covenant or other agreement giving rise to such termination by Buyer or during the cure period therefor provided in Sections 11.01(c)(i) or (ii) and (B) within twelve (12) months of such termination, Seller shall have entered into a definitive agreement with respect to, or Seller shall have consummated, an Acquisition Transaction, then Seller shall pay to Buyer an amount equal to the Termination Fee.

(e) Any payment of the Termination Fee required to be made pursuant to this Section 11.02 shall be made not more than two (2) business days after the date of the event giving rise to the obligation to make such payment, unless the Termination Fee is payable as a result of the termination of this Agreement by Seller pursuant to Section 11.01(d)(iii), in which case, the Termination Fee shall be payable concurrently with such termination. All payments under this Section 11.02 shall be made by wire transfer of immediately available funds to an account designated by Buyer.

Buyer shall be reimbursed by Seller for all fees, costs and other expenses incurred by Buyer in connection with enforcing its right to any Termination Fee.

(f) Buyer and Seller acknowledge that the agreements contained in this Section 11.02 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, Buyer would not enter into this Agreement. The Termination Fee amounts payable by Seller pursuant to this Section 11.02 constitute liquidated damages and not a penalty and shall be the sole monetary remedy of Buyer except in circumstances where no Termination Fee is payable. Accordingly, if Seller fails

A-58

promptly to pay any amount due pursuant to this Section 11.02 and, in order to obtain such payment, Buyer commences a suit which results in a judgment against Seller for the amount set forth in this Section 11.02, Seller shall pay to Buyer its costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of the Termination Fee at a rate per annum equal to three-month LIBOR (as reported in The Wall Street Journal (Northeast edition), or if not reported therein, in another authoritative source selected by the party to which the payment is due) plus 200 basis points as in effect on the date such payment was required to be made.

WHEREAS, concurrently with the execution of this Agreement, Buyer, Wesbanco Bank, Inc., Seller and First Sentry Bank, Inc. have entered into an Agreement and Plan of Merger (as such agreement may be subsequently amended or modified, the “Merger Agreement”), providing for, among other things, the merger of Seller with and into Buyer (the “Merger”);

WHEREAS, as of the date of this Agreement, the Shareholder beneficially owns and has sole voting power with respect to the number of Seller Shares, and holds stock options or other rights to acquire the number of Seller Shares, indicated onSchedule 1attached hereto;

WHEREAS, as used herein, the term “Shares” means all Seller Shares held by the Shareholder on the date of this Agreement and all Seller Shares that the Shareholder purchases, acquires the right to vote or acquires beneficial ownership of (as defined in Rule13d-3 of the Exchange Act, but excluding Seller Shares underlying unexercised stock options and Seller Shares held by the Shareholder in a fiduciary capacity) prior to the Expiration Date (as defined in Section 2 below), whether by the exercise of any stock options or otherwise;

WHEREAS, it is a condition to the willingness of Buyer to enter into the Merger Agreement that the Shareholder execute and deliver this Agreement; and

WHEREAS, all capitalized terms used in this Agreement without definition herein shall have the meanings ascribed to them in the Merger Agreement.

NOW,THEREFORE, in consideration of the foregoing recitals, the mutual covenants and agreements contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the Shareholder and Buyer agree as follows:

1. Agreement to Vote Shares. The Shareholder agrees that, prior to the Expiration Date (as defined in Section 2 hereof), at any meeting of the shareholders of Seller, or any adjournment or postponement thereof, or in connection with any written consent of the shareholders of Seller, with respect to the Merger, the Merger Agreement or any Acquisition Proposal, the Shareholder shall:

(a) appear at such meeting or otherwise cause the Shares to be counted as present thereat for purposes of calculating a quorum; and

(b) vote (or cause to be voted), or execute and deliver a written consent (or cause a written consent to be executed and delivered) covering, all of the Shares that such Shareholder shall be entitled to so vote (i) in favor of adoption of the Merger Agreement and the transactions contemplated thereby, including the Merger, and any action that could reasonably be expected to facilitate the Merger; (ii) against any action, proposal, transaction or agreement that could reasonably be expected to result in a breach of any covenant, representation or warranty, or any other obligation or agreement, of Seller contained in the Merger Agreement or of the Shareholder contained in this Agreement, or that could reasonably be expected to impede, interfere with, delay, discourage, adversely affect, inhibit or preclude the timely consummation of the Merger or the fulfillment of a condition under the Merger Agreement to Seller’s and Buyer’s respective obligations to consummate the Merger or change in any manner the voting rights of any class of shares of Seller (including any amendments to Seller’s articles of incorporation or bylaws); and (iii) against any Acquisition Proposal, or any agreement or transaction that is intended, or could reasonably be expected, to impede, interfere with, delay, postpone, discourage or adversely affect the consummation of the Merger or any of the transactions contemplated by the Merger Agreement.

Any such vote shall be cast or consent shall be given in accordance with such procedures relating thereto so as to ensure that it is duly counted for purposes of determining that a quorum is present and for purposes of recording the results of such vote or consent.

2. Expiration Date. As used in this Agreement, the term “Expiration Date” shall mean the earliest to occur of (i) the Effective Time, (ii) the date the Merger Agreement is terminated pursuant to Article Eleven thereof, or (iii) written notice by Buyer to Shareholder of the termination of this Agreement. Upon termination or expiration of this Agreement, no party shall have any further obligations or liabilities under this Agreement;provided,however, that such termination or expiration shall not relieve any party from liability for any willful breach of this Agreement prior to the termination or expiration hereof.

3. Agreement to Retain Shares; No Voting Trusts.

(a) Until the receipt of the requisite approval of the shareholders of Seller, the Shareholder shall not, except as contemplated by this Agreement or the Merger Agreement, directly or indirectly, sell, assign, transfer, offer, exchange, pledge or otherwise dispose of or encumber (including, without limitation, by the creation of a Lien (as defined in Section 4(c) below) (each, a “Transfer”), or enter into any contract, option, commitment or other arrangement or understanding with respect to, or consent to, any Transfer of, any Shares beneficially owned by the Shareholder or the Shareholder’s voting or economic interest therein. Notwithstanding the foregoing, the Shareholder may make Transfers (a) by will or by operation of law, in which case this Agreement shall bind the transferee, (b) in connection with estate and charitable planning purposes, including Transfers to relatives, trusts and charitable organizations, subject to the transferee’s agreement in writing, in form and substance reasonably satisfactory to Buyer, to be bound by the terms of, and perform the obligations of the Shareholder under, this Agreement, (c) to another shareholder of Seller who previously entered into a Voting Agreement with Buyer and (d) with Buyer’s prior written consent, such consent to be granted or withheld in Buyer’s sole discretion.

(b) The Shareholder agrees that the Shareholder shall not, and shall not permit any entity under the Shareholder’s control to, deposit any of the Shares in a voting trust, grant any proxies with respect to the Shares or subject any of the Shares to any arrangement with respect to the voting of the Shares other than agreements entered into with the Buyer.

4. Representations and Warranties of Shareholder. The Shareholder hereby represents and warrants to Buyer as follows:

(a) the Shareholder has the complete and unrestricted power and the unqualified right to enter into, execute, deliver and perform its obligations under this Agreement, and no consent, approval, authorization or filing on the part of the Shareholder is required in connection therewith;

(b) this Agreement has been duly and validly executed and delivered by the Shareholder and, assuming this Agreement constitutes a valid and binding agreement of Buyer, is a valid and legally binding agreement of the Shareholder, enforceable against the Shareholder in accordance with its terms (except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and similar laws of general applicability relating to or affecting creditors’ rights or by general equity principles);

(c) the Shareholder beneficially owns the number of Shares indicated onSchedule 1 (the “Original Shares”), free and clear of any liens, claims, charges or other encumbrances or restrictions of any kind whatsoever (“Liens”);

(d) except pursuant to this Agreement, the Shareholder has sole, and otherwise unrestricted, voting and investment power with respect to the Original Shares, and there are no options, warrants or other rights, agreements, arrangements or commitments of any character to which the Shareholder is a party relating to the pledge, disposition or voting of any of the Original Shares and there are no voting trusts or voting agreements with respect to the Original Shares;

A-A-2

(e) the Shareholder does not beneficially own any Seller Shares other than (i) the Original Shares and (ii) any options, warrants or other rights to acquire any additional shares of Seller Shares or any security exercisable for or convertible into shares of Seller Shares indicated onSchedule 1;

(f) the execution and delivery of this Agreement by the Shareholder does not, and the performance by the Shareholder of his, her or its obligations hereunder and the consummation by the Shareholder of the transactions contemplated hereby will not, violate or conflict with, or constitute a breach of or default (with or without notice or lapse of time or both) under, any agreement, instrument, contract or other obligation or any order, arbitration award, judgment or decree to which the Shareholder is a party or by which the Shareholder is bound, or any statute, rule or regulation to which the Shareholder or the Shareholder’s property or assets is subject or, in the event that the Shareholder is a corporation, partnership, trust or other entity, any bylaw or other organizational document of the Shareholder.

5.No Solicitation. From and after the date hereof until the Expiration Date, the Shareholder, solely in his, her or its capacity as a shareholder of Seller, shall not, nor shall such Shareholder authorize any partner, officer, director, advisor or representative of, such Shareholder or any of his, her or its affiliates to (and, to the extent applicable to the Shareholder, such Shareholder shall use reasonable best efforts to prohibit any of his, her or its representatives or affiliates to), (a) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal, (b) participate in any discussions or negotiations regarding any Acquisition Proposal, or furnish, or otherwise afford access, to any person (other than Buyer) any information or data with respect to Seller or any Seller Subsidiary or otherwise relating to an Acquisition Proposal, (c) enter into any agreement, agreement in principle or letter of intent with respect to an Acquisition Proposal, (d) solicit proxies or become a “participant” in a “solicitation” (as such terms are defined in Regulation 14A under the Exchange Act) with respect to an Acquisition Proposal (other than the Merger Agreement) or otherwise encourage or assist any party in taking or planning any action that would compete with, restrain or otherwise serve to interfere with or inhibit the timely consummation of the Merger in accordance with the terms of the Merger Agreement, (e) initiate a shareholders’ vote or action by consent of Seller’s shareholders with respect to an Acquisition Proposal, or (f) except by reason of this Agreement, become a member of a “group” (as such term is used in Section 13(d) of the Exchange Act) with respect to any voting securities of Seller that takes any action in support of an Acquisition Proposal.

6. Specific Enforcement. The Shareholder has signed this Agreement intending to be legally bound thereby. The parties hereto agree that irreparable damage would occur in the event any provision of this Agreement was not performed in accordance with the terms hereof and the Shareholder expressly agrees that this Agreement shall be specifically enforceable in any court of competent jurisdiction in accordance with its terms against the Shareholder, in addition to any other remedy that Buyer may have at law or in equity. All of the covenants and agreements contained in this Agreement shall be binding upon, and inure to the benefit of, the respective parties and their permitted successors, assigns, heirs, executors, administrators and other legal representatives, as the case may be, but, except as otherwise specifically provided herein, neither this Agreement nor any of the rights, interests or obligations of the Shareholder hereunder may be assigned without the prior written consent of Buyer.

7. No Waivers. No waivers of any breach of this Agreement extended by Buyer to the Shareholder shall be construed as a waiver of any rights or remedies of Buyer with respect to any other shareholder of Seller who has executed an agreement substantially in the form of this Agreement with respect to Shares beneficially owned by such shareholder or with respect to any subsequent breach by the Shareholder or any other such shareholder of Seller. No waiver of any provisions hereof by either party shall be deemed a waiver of any other provisions hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

8. No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Buyer any direct or indirect ownership or incidence of ownership of or with respect to any of the Shares. All rights, ownership and

A-A-3

economic benefits of and relating to the Shares shall remain vested in and belong to the Shareholder, and Buyer shall have no authority to direct the Shareholder in the voting or disposition of any of the Shares, except as otherwise provided in this Agreement.

9. Capacity as Shareholder. The Shareholder is signing this Agreement solely in the Shareholder’s capacity as a shareholder of Seller, and not in the Shareholder’s capacity as a director, officer or employee of Seller or any Seller Subsidiary or in the Shareholder’s capacity as a trustee or fiduciary of any employee benefit plan or trust. Notwithstanding anything herein to the contrary, nothing herein shall in any way (a) restrict a director and/or officer of Seller in the exercise of his or her fiduciary duties, consistent with the terms of the Merger Agreement, as a director and/or officer of Seller or in his or her capacity as a trustee or fiduciary of any employee benefit plan or trust, or (b) prevent or be construed to create any obligation on the part of any director and/or officer of Seller or any trustee or fiduciary of any employee benefit plan or trust from taking any action or omitting to take any action in such capacity.

10. Entire Agreement; Amendments. This Agreement supersedes all prior agreements, written or oral, between the parties hereto with respect to the subject matter hereof and contains the entire agreement between the parties with respect to the subject matter hereof. This Agreement may not be amended, supplemented or modified, and no provisions hereof may be modified or waived, except by an instrument in writing signed by each party hereto.

Ladies and Gentlemen:

First Sentry Bancshares, Inc. (“Seller”), First Sentry Bank, Inc., a wholly-owned subsidiary of Seller (“Seller Sub”), Wesbanco, Inc. (“Buyer”) and Wesbanco Bank, Inc., a wholly-owned subsidiary of Buyer (“Buyer Sub”), are proposing to enter into an Agreement and Plan of Merger (the “Agreement”) pursuant to which Seller will merge with and into Buyer with Buyer being the surviving corporation (the “Merger”) and, immediately after the Merger, Seller Sub will merge with and into Buyer Sub with Buyer Sub being the surviving bank corporation. Pursuant to the terms and conditions of the Agreement, at the Effective Time, each share of common stock, par value $1.00 per share, of Seller (“Seller Common Stock”) issued and outstanding immediately prior to the Effective Time, except for certain shares of Seller Common Stock as specified in the Agreement, will be converted into and shall thereafter represent the right to receive 1.5869 shares (the “Exchange Ratio”) of common stock of Buyer, par value $2.0833 per share (“Buyer Common Stock”). Capitalized terms used herein without definition have the meanings assigned to them in the Agreement. The terms and conditions of the Merger are more fully set forth in the Agreement. You have requested our opinion as to the fairness, from a financial point of view, of the Exchange Ratio to the holders of Seller Common Stock.

Sandler O’Neill & Partners, L.P. (“Sandler O’Neill”, “we” or “our”), as part of its investment banking business, is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions. In connection with this opinion, we have reviewed and considered, among other things: (i) an execution copy of the Agreement, dated as of November 13, 2017; (ii) certain publicly available financial statements and other historical financial information of Seller and Seller Sub that we deemed relevant; (iii) certain publicly available financial statements and other historical financial information of Buyer that we deemed relevant; (iv) certain internal financial projections for Seller for the year ending December 31, 2017 as well as an estimated annual earnings growth rate for the years thereafter, as provided by the senior management of Seller; (v) certain internal financial projections for Buyer for the years ending December 31, 2017 through December 31, 2020, as well as an estimated long-term earnings per share growth rate and estimated dividends per share for the years thereafter, as provided by the senior management of Buyer; (vi) publicly available mean and median analyst earnings per share estimates for Buyer for the years ending December 31, 2017 through December 31, 2019; (vii) the pro forma financial impact of the Merger on Buyer based on certain assumptions relating to purchase accounting adjustments, cost savings and transaction expenses, as well as earnings per share estimates for Seller for the years ending December 31, 2018 and December 31, 2019 and a long-term annual growth rate for Seller for the years thereafter, and earnings per share

estimates for Buyer for the years ending December 31, 2018 through December 31, 2020 as well as a long-term annual growth rate for Buyer for the years thereafter, as provided by the senior management of Buyer; (viii) the publicly reported historical price and trading activity for Buyer Common Stock, including a comparison of certain stock market information for Buyer Common Stock and certain stock indices as well as publicly available information for certain other similar companies, the securities of which are publicly traded; (ix) a comparison of certain financial information for Seller and Buyer with similar financial institutions for which information is publicly available; (x) the financial terms of certain recent business combinations in the banking industry (on a regional and nationwide basis), to the extent publicly available; (xi) the current market environment generally and the banking environment in particular; and (xii) such other information, financial studies, analyses and investigations and financial, economic and market criteria as we considered relevant. We also discussed with certain members of the management of Seller and its representatives the business, financial condition, results of operations and prospects of Seller and held similar discussions with certain members of the management of Buyer and its representatives regarding the business, financial condition, results of operations and prospects of Buyer.

In performing our review, we have relied upon the accuracy and completeness of all of the financial and other information that was available to and reviewed by us from public sources, that was provided to us by Seller or Buyer or their respective representatives, or that was otherwise reviewed by us, and we have assumed such accuracy and completeness for purposes of rendering this opinion without any independent verification or investigation. We have relied on the assurances of the respective managements of Seller and Buyer that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. We have not been asked to and have not undertaken an independent verification of any of such information and we do not assume any responsibility or liability for the accuracy or completeness thereof. We did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Seller or Buyer or any of their respective subsidiaries, nor have we been furnished with any such evaluations or appraisals. We render no opinion or evaluation on the collectability of any assets or the future performance of any loans of Seller or Buyer. We did not make an independent evaluation of the adequacy of the allowance for loan losses of Seller or Buyer, or of the combined entity after the Merger, and we have not reviewed any individual credit files relating to Seller or Buyer. We have assumed, with your consent, that the respective allowances for loan losses for both Seller and Buyer are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Sandler O’Neill used certain internal financial projections for Seller for the year ending December 31, 2017 as well as an estimated annual earnings growth rate for the years thereafter, as provided by the senior management of Seller. In addition, Sandler O’Neill used certain internal financial projections for Buyer for the years ending December 31, 2017 through December 31, 2020, as well as an estimated long-term earnings per share growth rate and estimated dividends per share for the years thereafter, as provided by the senior management of Buyer. Sandler O’Neill also received and used in its pro forma analyses certain assumptions relating to purchase accounting adjustments, cost savings and transaction expenses, as well as earnings per share estimates for Seller for the years ending December 31, 2018 and December 31, 2019 and a long-term annual growth rate for Seller for the years thereafter, and earnings per share estimates for Buyer for the years ending December 31, 2018 through December 31, 2020 as well as a long-term annual growth rate for Buyer for the years thereafter, as provided by the senior management of Buyer. With respect to the foregoing information, the respective managements of Seller and Buyer confirmed to us that such information reflected the

B-2

best currently available projections, estimates and judgments of those respective managements as to the future financial performance of Seller and Buyer, respectively, and the other matters covered thereby, and we assumed that the future financial performance reflected in such information would be achieved. We express no opinion as to such information, or the assumptions on which such information is based. We have also assumed that there has been no material change in the respective assets, financial condition, results of operations, business or prospects of Seller or Buyer since the date of the most recent financial statements made available to us. We have assumed in all respects material to our analysis that Seller and Buyer will remain as going concerns for all periods relevant to our analysis.

We have also assumed, with your consent, that (i) each of the parties to the Agreement will comply in all material respects with all material terms and conditions of the Agreement and all related agreements, that all of the representations and warranties contained in such agreements are true and correct in all material respects, that each of the parties to such agreements will perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements are not and will not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on Seller, Buyer or the Merger or any related transaction, (iii) the Merger and any related transactions will be consummated in accordance with the terms of the Agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements, and (iv) the Merger will qualify as atax-free reorganization for federal income tax purposes. Finally, with your consent, we have relied upon the advice that Seller has received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Merger and the other transactions contemplated by the Agreement. We express no opinion as to any such matters.

Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof could materially affect this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or otherwise comment upon events occurring after the date hereof. We express no opinion as to the trading value of Buyer Common Stock at any time or what the value of Buyer Common Stock will be once it is actually received by the holders of Seller Common Stock.

We have acted as Seller’s financial advisor in connection with the Merger and will receive a fee for our services, a significant portion of which is contingent upon the closing of the Merger. We will also receive a fee for rendering this opinion, which opinion fee will be credited in full towards the portion of the transaction fee which will become payable to Sandler O’Neill on the day of closing of the Merger. Seller has also agreed to indemnify us against certain claims and liabilities arising out of our engagement and to reimburse us for certain of ourout-of-pocket expenses incurred in connection with our engagement. We have not received any compensation for any other investment banking services provided to Seller in the two years preceding the date of this opinion. In the two years preceding the date hereof we have not provided any investment banking services to Buyer. In the ordinary course of our business as a broker-dealer, we may purchase securities from and sell securities to Buyer and its affiliates. We may also actively trade the equity and debt securities of Buyer and its affiliates for our own account and for the accounts of our customers.

B-3

Our opinion is directed to the Board of Directors of Seller in connection with its consideration of the Agreement and the Merger and does not constitute a recommendation to any shareholder of Seller as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the Agreement and the Merger. Our opinion is directed only to the fairness, from a financial point of view, of the Exchange Ratio to the holders of Seller Common Stock and does not address the underlying business decision of Seller to engage in the Merger, the form or structure of the Merger or any other transactions contemplated in the Agreement, the relative merits of the Merger as compared to any other alternative transactions or business strategies that might exist for Seller or the effect of any other transaction in which Seller might engage. We also do not express any opinion as to the fairness of the amount or nature of the compensation to be received in the Merger by any officer, director or employee of Seller or Buyer, or any class of such persons, if any, relative to the compensation to be received in the Merger by any other shareholder. This opinion has been approved by Sandler O’Neill’s fairness opinion committee. This opinion shall not be reproduced without Sandler O’Neill’s prior written consent;provided, however, Sandler O’Neill will provide its consent for the opinion to be included in regulatory filings to be completed in connection with the Merger.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio is fair to holders of Seller Common Stock from a financial point of view.

Very truly yours,

(C) The corporation’s estimate of the fair value of the shares;

A shareholder who fails to withdraw from the appraisal process by that date may not withdraw without the corporation’s written consent.

(c) A shareholder who does not execute and return the form and, in the case of certificated shares, deposit the shareholder’s share certificates where required, each by the date set forth in the notice described in subsection (b), section one thousand three hundredtwenty-two of this article, is not entitled to payment under this article.

§31D-13-1324. Payment

(a) Except as provided in section one thousand three hundred twenty-five of this article, within thirty days after the form required by paragraph (B), subdivision (2), subsection (b), section one thousand three hundredtwenty-two of this article is due, the corporation shall pay in cash to those shareholders who complied with subsection (a), section one thousand three hundred twenty-three of this article the amount the corporation estimates to be the fair value of their shares, plus interest.

(2) A statement of the corporation’s estimate of the fair value of the shares, which estimate must equal or exceed the corporation’s estimate given pursuant to paragraph (C), subdivision (2), subsection (b), section one thousand three hundredtwenty-two of this article; and

(3) A statement that shareholders described in subsection (a) of this section have the right to demand further payment under section one thousand three hundredtwenty-six of this article and that if any shareholder does not make a demand for further payment within the time period specified, shareholder is deemed to have accepted the payment in full satisfaction of the corporation’s obligations under this article.

C-5

(a) A corporation may elect to withhold payment required by section one thousand three hundred twenty-four of this article from any shareholder who did not certify that beneficial ownership of all of the shareholder’s shares for which appraisal rights are asserted was acquired before the date set forth in the appraisal notice sent pursuant to subdivision (1), subsection (b), section one thousand three hundredtwenty-two of this article.

(b) If the corporation elected to withhold payment under subsection (a) of this section, it must, within thirty days after the form required by paragraph (B), subdivision (2), subsection (b), section one thousand three hundredtwenty-two of this article is due, notify all shareholders who are described in subsection (a) of this section:

(1) Of the information required by subdivision (1), subsection (b), section one thousand three hundred twenty-four of this article;

(2) Of the corporation’s estimate of fair value pursuant to subdivision (2), subsection (b), section one thousand three hundred twenty-four of this article;

(4) That those shareholders who wish to accept the offer must notify the corporation of their acceptance of the corporation’s offer within thirty days after receiving the offer; and

(5) That those shareholders who do not satisfy the requirements for demanding appraisal under section one thousand three hundredtwenty-six of this article are deemed to have accepted the corporation’s offer.

(c) Within ten days after receiving the shareholder’s acceptance pursuant to subsection (b) of this section, the corporation must pay in cash the amount it offered under subdivision (2), subsection (b) of this section to each shareholder who agreed to accept the corporation’s offer in full satisfaction of the shareholder’s demand.

(d) Within forty days after sending the notice described in subsection (b) of this section, the corporation must pay in cash the amount it offered to pay under subdivision (2), subsection (b) of this section to each shareholder described in subdivision (5), subsection (b) of this section.

§31D-13-1326. Procedure if shareholder dissatisfied with payment or offer

(a) A shareholder paid pursuant to section one thousand three hundred twenty-four of this article who is dissatisfied with the amount of the payment must notify the corporation in writing of that shareholder’s estimate of the fair value of the shares and demand payment of that estimate plus interest and less any payment due under section one thousand three hundred twenty-four of this article. A shareholder offered payment under section one thousand three hundred twenty-five of this article who is dissatisfied with that offer must reject the offer and demand payment of the shareholder’s stated estimate of the fair value of the shares plus interest.

(b) A shareholder who fails to notify the corporation in writing of that shareholder’s demand to be paid the shareholder’s stated estimate of the fair value plus interest under subsection (a) of this section within thirty days after receiving the corporation’s payment or offer of payment under sections one thousand three hundred twenty-four or one thousand three hundred twenty-five of this article, respectively, waives the right to demand payment under this section and is entitled only to the payment made or offered pursuant to those respective sections.

§31D-13-1330. Court action

(a) If a shareholder makes demand for payment under section one thousand three hundredtwenty-six of this article which remains unsettled, the corporation shall commence a proceeding within sixty days after receiving

C-6

the payment demand and petition the court to determine the fair value of the shares and accrued interest. If the corporation does not commence the proceeding within thesixty-day period, it shall pay in cash to each shareholder the amount the shareholder demanded pursuant to section one thousand three hundredtwenty-six of this article plus interest.

(b) The corporation shall make all shareholders, whether or not residents of this state, whose demands remain unsettled parties to the proceeding as in an action against their shares, and all parties must be served with a copy of the petition. Nonresidents may be served by registered or certified mail or by publication as provided by law.

(c) The jurisdiction of the court in which the proceeding is commenced is plenary and exclusive. The court may appoint one or more persons as appraisers to receive evidence and recommend a decision on the question of fair value. The appraisers have the powers described in the order appointing them, or in any amendment to it. The shareholders demanding appraisal rights are entitled to the same discovery rights as parties in other civil proceedings. There is no right to a jury trial.

(d) Each shareholder made a party to the proceeding is entitled to judgment: (1) For the amount, if any, by which the court finds the fair value of the shareholder’s shares, plus interest, exceeds the amount paid by the corporation to the shareholder for the shares; or (2) for the fair value, plus interest, of the shareholder’s shares for which the corporation elected to withhold payment under section one thousand three hundred twenty-five of this article.

§31D-13-1331. Court costs and counsel fees

(a) The court in an appraisal proceeding commenced under section one thousand three hundred thirty of this article shall determine all costs of the proceeding, including the reasonable compensation and expenses of appraisers appointed by the court. The court shall assess the costs against the corporation, except that the court may assess costs against all or some of the shareholders demanding appraisal, in amounts the court finds equitable, to the extent the court finds the shareholders acted arbitrarily, vexatiously, or not in good faith with respect to the rights provided by this article.

(b) The court in an appraisal proceeding may also assess the fees and expenses of counsel and experts for the respective parties, in amounts the court finds equitable:

(1) Against the corporation and in favor of any or all shareholders demanding appraisal if the court finds the corporation did not substantially comply with the requirements of section one thousand three hundred twenty, one thousand three hundredtwenty-two, one thousand three hundred twenty-four or one thousand three hundred twenty-five of this article; or

(2) Against either the corporation or a shareholder demanding appraisal, in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed acted arbitrarily, vexatiously or not in good faith with respect to the rights provided by this article.

(c) If the court in an appraisal proceeding finds that the services of counsel for any shareholder were of substantial benefit to other shareholders similarly situated, and that the fees for those services should not be assessed against the corporation, the court may award to counsel reasonable fees to be paid out of the amounts awarded the shareholders who were benefitted.

(d) To the extent the corporation fails to make a required payment pursuant to section one thousand three hundred twenty-four, one thousand three hundred twenty-five, or one thousand three hundredtwenty-six of this article, the shareholder may sue directly for the amount owed and, to the extent successful, are to be entitled to recover from the corporation all costs and expenses of the suit, including counsel fees.

PART II

INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 20.Indemnification of Directors and Officers.

WesBanco’s Bylaws provide, and West Virginia law permits, the indemnification of directors and officers against certain liabilities. Officers and directors of WesBanco and its subsidiaries are indemnified, to the maximum extent permitted under the West Virginia Business Corporation Act (including advanced indemnification payments), against liabilities incurred in connection with proceedings in which they are made parties by reason of their being or having been directors or officers of the corporation, except for certain prohibitions set forth in WesBanco’s Bylaws regarding “prohibited indemnification payments.” WesBanco does provide indemnity insurance to its officers and directors. Such insurance will not, however, indemnify officers or directors for willful misconduct or gross negligence in the performance of a duty to WesBanco.

I. Article VI of the Bylaws of WesBanco provides:

Indemnification of Directors and Officers

SECTION 1. Indemnification. Each director and officer, whether or not then in office, shall be indemnified by the corporation against liability incurred by and imposed upon him in connection with or resulting from any action, suit or proceeding, to which he may be made a party by reason of his being or having been a director or officer of the corporation, or of any other company which he served at the request of the corporation, to the maximum extent permitted under the West Virginia Business Corporation Act, except as prohibited by Section 2 and Section 4 of this Article VI. The foregoing right of indemnification shall not be exclusive of other rights to which he may be entitled as a matter of law. Expenses incurred in defending a civil or criminal action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding as authorized by the board of directors in accordance with the provisions of the West Virginia Business Corporation Act.

SECTION 2. Prohibited Indemnification Payment. Notwithstanding the provisions of Section 1 of this Article VI, no director or officer shall receive a “prohibited indemnification payment,” which is any payment or agreement to make a payment to pay or reimburse such director or officer for any liability or legal expenses in any administrative proceeding brought by the appropriate federal banking agency that results in a final order or settlement in which the director or officer is assessed a civil money penalty, is removed or prohibited from conducting the business of banking, or is required to cease an action or take any affirmative action, including making restitution, with respect to Wesbanco Bank, Inc. or the corporation.

SECTION 3. Insurance. The corporation may purchase commercial insurance to cover certain costs that the corporation incurs under the indemnification provisions of Section 1 of this Article VI. Costs that may be covered include legal expenses and restitution that an individual may be ordered to make to the corporation. Such insurance may not, however, pay or reimburse a director or officer for any final judgment or civil money penalty assessed against such individual. Furthermore, partial indemnification for legal expenses is permitted in connection with a settlement when there is a formal and final finding that the director or officer has not breached a fiduciary duty, engaged in unsafe or unsound practices, and is not subject to a final prohibition order.

SECTION 4. Determination that Indemnification is Proper. The corporation may make or agree to make a reasonable indemnification payment if all of the following conditions are met: (i) the board of directors investigates and determines in writing that the director or officer acted in good faith and in the best interests of Wesbanco Bank, Inc.; (ii) the board of directors investigates and determines that the payment will not materially adversely affect the safety and soundness of Wesbanco Bank, Inc. or the corporation; (iii) the payment does not fall within the definition of a prohibited indemnification payment; and (iv) the director or officer agrees in writing to reimburse the corporation, to the extent not covered by permissible insurance, for advanced indemnification payments that subsequently become prohibited indemnification payments.

II-1

II. W. Va. CodeSection 31D-8-851 throughSection 31D-8-856 provides:

Section 31D-8-851. Permissible Indemnification.

(a) Except as otherwise provided in this section, a corporation may indemnify an individual who is a party to a proceeding because he or she is a director against liability incurred in the proceeding if:

(1) (A) He or she conducted himself or herself in good faith; and

(B) He or she reasonably believed: (i) In the case of conduct in his or her official capacity, that his or her conduct was in the best interests of the corporation; and (ii) in all other cases, that his or her conduct was at least not opposed to the best interests of the corporation; and

(C) In the case of any criminal proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful; or

(2) He or she engaged in conduct for which broader indemnification has been made permissible or obligatory under a provision of the articles of incorporation as authorized by subdivision (5), subsection (b), section two hundred two, article two of this chapter.

(b) A director’s conduct with respect to an employee benefit plan for a purpose he or she reasonably believed to be in the interests of the participants in, and the beneficiaries of, the plan is conduct that satisfies the requirement of subparagraph (ii), paragraph (B), subdivision (1), subsection (a) of this section.

(c) The termination of a proceeding by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, is not determinative that the director did not meet the relevant standard of conduct described in this section.

(d) Unless ordered by a court under subdivision (3), subsection (a), section eight hundred fifty-four of this article, a corporation may not indemnify a director:

(1) In connection with a proceeding by or in the right of the corporation, except for reasonable expenses incurred in connection with the proceeding if it is determined that the director has met the relevant standard of conduct under subsection (a) of this section; or

(2) In connection with any proceeding with respect to conduct for which he or she was adjudged liable on the basis that he or she received a financial benefit to which he or she was not entitled, whether or not involving action in his or her official capacity.

Section 31D-8-852. Mandatory Indemnification.

A corporation must indemnify a director who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he or she was a party because he or she was a director of the corporation against reasonable expenses incurred by him or her in connection with the proceeding.

Section 31D-8-853. Advance for Expenses.

(a) A corporation may, before final disposition of a proceeding, advance funds to pay for or reimburse the reasonable expenses incurred by a director who is a party to a proceeding because he or she is a director if he or she delivers to the corporation:

(1) A written affirmation of his or her good faith belief that he or she has met the relevant standard of conduct described in section eight hundredfifty-one of this article or that the proceeding involves conduct for which liability has been eliminated under a provision of the articles of incorporation as authorized by subdivision (4), subsection (b), section two hundred two, article two of this chapter; and

II-2

(2) His or her written undertaking to repay any funds advanced if he or she is not entitled to mandatory indemnification under section eight hundredfifty-two of this article and it is ultimately determined under section eight hundred fifty-four or eight hundred fifty-five of this article that he or she has not met the relevant standard of conduct described in section eight hundredfifty-one of this article.

(b) The undertaking required by subdivision (2), subsection (a) of this section must be an unlimited general obligation of the director but need not be secured and may be accepted without reference to the financial ability of the director to make repayment.

(c) Authorizations under this section are to be made:

(1) By the board of directors:

(A) If there are two or more disinterested directors, by a majority vote of all the disinterested directors, a majority of whom constitute a quorum for this purpose, or by a majority of the members of a committee of two or more disinterested directors appointed by a vote; or

(B) If there are fewer than two disinterested directors, by the vote necessary for action by the board in accordance with subsection (c), section eight hundred twenty-four of this article in which authorization directors who do not qualify as disinterested directors may participate; or

(2) By the shareholders, but shares owned by or voted under the control of a director who at the time does not qualify as a disinterested director may not be voted on the authorization; or

(3) By special legal counsel selected in a manner in accordance with subdivision (2), subsection (b), section eight hundred fifty-five of this article.

Section 31D-8-854. Circuit Court-Ordered Indemnification and Advance for Expenses.

(a) A director who is a party to a proceeding because he or she is a director may apply for indemnification or an advance for expenses to the circuit court conducting the proceeding or to another circuit court of competent jurisdiction. After receipt of an application and after giving any notice it considers necessary, the circuit court shall:

(1) Order indemnification if the circuit court determines that the director is entitled to mandatory indemnification under section eight hundredfifty-two of this article;

(2) Order indemnification or advance for expenses if the circuit court determines that the director is entitled to indemnification or advance for expenses pursuant to a provision authorized by subsection (a), section eight hundred fifty-eight of this article; or

(3) Order indemnification or advance for expenses if the circuit court determines, in view of all the relevant circumstances, that it is fair and reasonable:

(A) To indemnify the director; or

(B) To advance expenses to the director, even if he or she has not met the relevant standard of conduct set forth in subsection (a), section eight hundredfifty-one of this article, failed to comply with section eight hundred fifty-three of this article or was adjudged liable in a proceeding referred to in subdivision (1) or (2), subsection (d), section eight hundredfifty-one of this article, but if he or she was adjudged so liable his or her indemnification is to be limited to reasonable expenses incurred in connection with the proceeding.

(b) If the circuit court determines that the director is entitled to indemnification under subdivision (1), subsection (a) of this section or to indemnification or advance for expenses under subdivision (2) of said

II-3

subsection, it shall also order the corporation to pay the director’s reasonable expenses incurred in connection with obtaining circuit court-ordered indemnification or advance for expenses. If the circuit court determines that the director is entitled to indemnification or advance for expenses under subdivision (3) of said subsection, it may also order the corporation to pay the director’s reasonable expenses to obtain circuit court-ordered indemnification or advance for expenses.

Section 31D-8-855. Determination and Authorization of Indemnification.

(a) A corporation may not indemnify a director under section eight hundredfifty-one of this article unless authorized for a specific proceeding after a determination has been made that indemnification of the director is permissible because he or she has met the relevant standard of conduct set forth in section eight hundredfifty-one of this article.

(b) The determination is to be made:

(1) If there are two or more disinterested directors, by the board of directors by a majority vote of all the disinterested directors, a majority of whom constitute a quorum for this purpose, or by a majority of the members of a committee of two or more disinterested directors appointed by a vote;

(2) By special legal counsel:

(A) Selected in the manner prescribed in subdivision (1) of this subsection; or

(B) If there are fewer than two disinterested directors, selected by the board of directors in which selection directors who do not qualify as disinterested directors may participate; or

(3) By the shareholders, but shares owned by or voted under the control of a director who at the time does not qualify as a disinterested director may not be voted on the determination.

(c) Authorization of indemnification is to be made in the same manner as the determination that indemnification is permissible, except that if there are fewer than two disinterested directors or if the determination is made by special legal counsel, authorization of indemnification is to be made by those entitled under paragraph (B), subdivision (2), subsection (b) of this section to select special legal counsel.

Section 31D-8-856. Indemnification of Officers.

(a) A corporation may indemnify and advance expenses under this part to an officer of the corporation who is a party to a proceeding because he or she is an officer of the corporation:

(1) To the same extent as a director; and

(2) If he or she is an officer but not a director, to a further extent as may be provided by the articles of incorporation, the bylaws, a resolution of the board of directors or contract except for:

(A) Liability in connection with a proceeding by or in the right of the corporation other than for reasonable expenses incurred in connection with the proceeding; or

(B) Liability arising out of conduct that constitutes:

(i) Receipt by him or her of a financial benefit to which he or she is not entitled;

(ii) An intentional infliction of harm on the corporation or the shareholders; or

(iii) An intentional violation of criminal law.

II-4

(b) The provisions of subdivision (2), subsection (a) of this section apply to an officer who is also a director if the basis on which he or she is made a party to the proceeding is an act or omission solely as an officer.

(c) An officer of a corporation who is not a director is entitled to mandatory indemnification under section eight hundredfifty-two of this article and may apply to a court under section eight hundred fifty-four of this article for indemnification or an advance for expenses in each case to the same extent to which a director may be entitled to indemnification or advance for expenses under those provisions.

Certain rules of the Federal Deposit Insurance Corporation limit the ability of certain depository institutions, their subsidiaries and their affiliated depository institution holding companies to indemnify affiliated parties, including institution directors. In general, subject to the ability to purchase directors’ and officers’ liability insurance and to advance professional expenses under certain circumstances, the rules prohibit such institutions from indemnifying a director for certain costs incurred with regard to an administrative or enforcement action commenced by any federal banking agency that results in a final order or settlement pursuant to which the director is assessed a civil money penalty, removed from office, prohibited from participating in the affairs of an insured depository institution or required to cease and desist from or take an affirmative action described in Section 8(b) of the Federal Deposit Insurance Act (12 U.S.C. § 1818(b)).

Item 22. Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

i. to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

ii. to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

iii. to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b)   (1) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(2) The registrant undertakes that every prospectus (i) that is filed pursuant to paragraph (1) immediately preceding or (ii) that purports to meet the requirements of section 10(a)(3) of the

II-6

Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(d) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(e) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(f) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
