PRELIMINARY—SUBJECT TO COMPLETION—DATED JANUARY 30, 2020

PROXY STATEMENT/PROSPECTUS

MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

Dear Shareholder:

On December 18, 2019, the boards of directors of CNB Financial Corporation, or CNB, and Bank of Akron, or Akron, each approved a merger agreement between CNB and Akron pursuant to which Akron will merge with and into CNB Bank, a Pennsylvania-chartered nonmember bank and wholly-owned subsidiary of CNB, with CNB Bank surviving the merger.

Akron is holding a special meeting for its shareholders to vote on the proposals necessary to complete the merger. The merger cannot be completed unless the holders oftwo-thirds of the shares of Akron common stock outstanding and entitled to vote at the special meeting vote to approve the merger agreement. The board of directors of Akron recommends that all shareholders vote “FOR” approval of the merger agreement.

The special meeting of Akron shareholders will be held at                    on                      , at             , local time.

Under the terms and conditions of the merger, the shareholders of Akron, as of the record date, will be able to elect to receive either (i) $215.00 in cash or (ii) 6.6729 shares of CNB common stock for each share of Akron common stock they own. Each Akron shareholder’s election is subject to proration provisions described in this proxy statement/prospectus that may modify the shareholder’s election to ensure that no more than 25% of the outstanding shares of Akron common stock (including any dissenters’ shares but excluding shares of Akron common stock to be canceled in connection with the merger) are exchanged for cash. The value of the stock consideration will depend on the market price of CNB common stock on the effective date of the merger. Akron shareholders will also receive cash in lieu of any fractional shares they would have otherwise received in the merger. CNB expects to issue up to 2,001,870 shares of its common stock in the merger.

Although the maximum number of shares of CNB common stock that holders of Akron common stock will be entitled to receive is fixed, the market value of the stock consideration will fluctuate with the market price of CNB common stock and will not be known at the time Akron shareholders vote on the merger. However, as described in more detail elsewhere in this proxy statement/prospectus, under the terms of the merger agreement, Akron has the right to terminate the merger agreement if the average closing price of CNB common stock for a specified period prior to closing is less than $25.77 and CNB common stock underperforms a specified peer-group index by more than 20%, unless CNB elects to increase the exchange ratio such that the implied value of the exchange ratio would be equivalent to the minimum implied value that would have avoided triggering this termination right, which would result in additional shares of CNB common stock being issued.

CNB common stock is listed on the NASDAQ Global Select Market under the symbol “CCNE” and Akron common stock is quoted on the Pink Open Market under the symbol “BARK”. On                     , 2020, the last practicable trading day before the printing of the attached proxy statement/prospectus, the closing price of CNB common stock was $            per share and the closing price of Akron common stock was $            per share. These prices may fluctuate between now and the closing of the merger. We urge you to obtain current market quotations for both CNB and Akron common stock.

Your vote is important regardless of the number of shares you own. Whether or not you plan to attend the special meeting, please take the time to vote by completing and mailing the enclosed proxy card as soon as possible to make sure your shares are represented at the special meeting. If you hold shares through a bank or broker, please use the voting instructions you have received from your bank or broker. If you submit a properly signed proxy card without indicating how you want to vote, your proxy will be counted as a vote “FOR” each of the proposals being voted on at Akron’s special meeting. The failure to vote by submitting your proxy or attending Akron’s special meeting and voting in person will have the same effect as a vote against approval of the merger agreement.

The accompanying document serves as the proxy statement for Akron’s special meeting and as the prospectus for the shares of CNB common stock to be issued in the merger. This proxy statement/prospectus describes the Akron special meeting, the merger, the documents related to the merger and other related matters. Please carefully review and consider this proxy statement/prospectus.Please give particular attention to the discussion under the heading “Risk Factors” beginning on page18 for risk factors relating to the transaction that you should consider.

Akron’s board of directors recommends that shareholders vote “FOR” the approval of the merger agreement, and “FOR” the approval of the adjournment of the special meeting, if necessary, in order to solicit additional proxies in favor of the merger agreement and the transactions contemplated by the merger agreement, including the merger.

Sincerely,

Stephen Forrestel

Chairman of the Board of Directors

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE AKRON SPECIAL MEETING

The following questions and answers are intended to address briefly some commonly asked questions regarding the merger and the Akron special meeting. These questions and answers may not address all questions that may be important to you as an Akron shareholder. To better understand these matters, and for a description of the legal terms governing the merger, you should carefully read this entire proxy statement/prospectus, including the annexes, as well as the documents that have been incorporated by reference in this proxy statement/prospectus.

Q: Why am I receiving this proxy statement/prospectus?

A: CNB and Akron have agreed to the acquisition of Akron by CNB under the terms of the merger agreement that is described in this proxy statement/prospectus. A copy of the merger agreement is attached to this proxy statement/prospectus asAnnex A. In order to complete the merger, Akron shareholders must vote to approve the merger agreement. Akron will hold a special meeting of shareholders to obtain this approval. This proxy statement/prospectus contains important information about the merger, the merger agreement, the special meeting of Akron shareholders and other related matters, and you should read it carefully. The enclosed voting materials for the Akron special meeting allow you to vote your shares of common stock without attending the special meeting in person.

We are delivering this proxy statement/prospectus to you as both a proxy statement of Akron and a prospectus of CNB. It is a proxy statement because the board of directors of Akron is soliciting proxies from Akron shareholders to vote on the approval of the merger agreement at the Akron special meeting of shareholders and adjournments of the special meeting, if necessary, for the purpose of soliciting additional proxies in favor of the foregoing proposal. Your proxy will be used at the Akron special meeting or at any adjournment or postponement of that special meeting. It is also a prospectus because CNB will issue CNB common stock to Akron shareholders who elect to receive shares of CNB common stock as consideration in the merger, and this prospectus contains information about that common stock.

Q: What will happen in the merger?

A: In the proposed merger, Akron will merge with and into CNB Bank, a wholly-owned subsidiary of CNB, with CNB Bank being the surviving entity.

Q: What are the proposals on which I am being asked to vote?

A: You are being asked to vote on the following proposals: (i) to approve the merger agreement and (ii) to approve one or more adjournments of the special meeting, if necessary, for the purpose of soliciting additional proxies in favor of the proposal to approve the merger agreement.

Q: What will I receive in the merger?

A: If the merger agreement is approved and the merger is subsequently completed, Akron shareholders will be entitled to receive for each of their shares of Akron common stock either (i) $215.00 in cash, without interest, or (ii) 6.6729 shares of CNB common stock.

You will have the opportunity to elect the form of consideration to be received for your shares, subject to proration and allocation procedures set forth in the merger agreement and described in this proxy statement/prospectus which may result in your receiving a portion of the merger consideration in a form other than that which you elected.

CNB may opt to increase the exchange ratio in specific circumstances where Akron could otherwise terminate the merger agreement. For more information regarding these termination rights and the adjustments that may result to the merger consideration, see “The Merger Agreement—Termination of the Merger Agreement” on page 75 for more information.

1

The value of the stock consideration is dependent upon the value of CNB common stock and, therefore, will fluctuate with the market price of CNB common stock. Accordingly, any change in the price of CNB common stock prior to the merger will affect the market value of the stock consideration that Akron shareholders may elect to receive as a result of the merger.

Q: What will happen to shares of CNB common stock in the merger?

A: Each share of CNB common stock outstanding held by CNB shareholders immediately before the merger will continue to represent one share of CNB common stock after the effective time. Accordingly, CNB shareholders will receive no consideration in the merger and the merger will not change the number of shares a CNB shareholder currently owns.

Q: Will I receive any fractional shares of CNB common stock as part of the merger consideration?

A: No. CNB will not issue any fractional shares of CNB common stock in the merger. Instead, CNB will pay you the cash value of a fractional share measured by the average of the daily closing prices of CNB common stock on The NASDAQ Global Select Market for the ten consecutive trading days immediately preceding, but not including, the trading day immediately prior to the closing date of the merger.

Q: Is there a termination fee potentially payable under the merger agreement?

A: Yes. Under certain circumstances, Akron or CNB may be required to pay the other party a termination fee if the merger agreement is terminated. See “The Merger Agreement–Termination Fee” on page 76 for more information.

Q: How do I make an election with respect to my shares of Akron common stock?

A: Each Akron shareholder will receive an election form, which you should complete and return according to the instructions printed on the form. The election deadline will be 5:00 p.m., New York City time, on                 , 2020, the date prior to the date of the special meeting, or the election deadline. A copy of the election form is being mailed under separate cover on or about the date of this proxy statement/prospectus. If you do not send in the election form by the deadline, you will be deemed not to have made an election and you may be paid CNB common stock. See “The Merger Agreement—Election Procedures for Shareholders; Surrender of Stock Certificates” on page 62 for more information.

Q: Can I change or revoke my election with respect to my shares of Akron common stock?

A: You may change your election at any time prior to the election deadline by submitting to American Stock Transfer & Trust Company, LLC written notice accompanied by a properly completed and signed, revised election form. Shareholders will not be entitled to change or revoke their elections following the election deadline. All elections will be revoked automatically if the merger agreement is terminated.

Q: What are the material U.S. federal income tax consequences of the merger to U.S. holders of shares of Akron common stock?

A: The merger is intended to qualify for U.S. federal income tax purposes as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, which we refer to as the Code. Therefore, for U.S. federal income tax purposes, as a result of the merger, it is expected that a U.S. holder of shares of Akron common stock generally will only recognize gain (but not loss) in an amount not to exceed the cash (if any) received as part of the merger consideration but will recognize gain or loss (1) if such holder received the entirety of its consideration in cash or (2) with respect to any cash received in lieu of fractional shares of CNB common stock. See “The Merger—Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 54.

2

Tax matters are very complicated, and the tax consequences of the merger to each U.S. holder of Akron common stock may depend on such holder’s particular facts and circumstances. Holders of Akron common stock are urged to consult with their tax advisors to fully understand the tax consequences of the merger.

Q: Will I be able to trade the shares of CNB common stock that I receive in the merger?

A: You may freely trade the shares of CNB common stock issued in the merger, unless you are an “affiliate” of CNB as defined by Rule 144 under the Securities Act of 1933, as amended, or the Securities Act. Affiliates consist of individuals or entities that control, are controlled by, or are under the common control with CNB and include the executive officers and directors and may include significant shareholders of CNB.

Q: What are the conditions to completion of the merger?

A: The obligations of CNB and Akron to complete the merger are subject to the satisfaction or waiver of certain closing conditions contained in the merger agreement, including the receipt of required regulatory approvals and tax opinions, and the approval of the merger agreement by the shareholders of Akron.

Q: When do you expect the merger to be completed?

A: We will complete the merger when all of the conditions to completion contained in the merger agreement are satisfied or waived, including obtaining required regulatory approvals and the approval of the merger agreement by Akron shareholders at Akron’s special meeting. While we expect the merger to be completed no later than the third quarter of 2020, because fulfillment of some of the conditions to completion of the merger is not entirely within our control, we cannot assure you of the actual timing.

Q: What Akron shareholder approval is required to complete the merger?

A: The merger cannot be completed unless the holders oftwo-thirds of the shares of Akron common stock outstanding and entitled to vote at the Akron special meeting vote to approve the merger agreement.

Q: Are there any Akron shareholders already committed to voting in favor of the merger agreement?

A: Yes. Each of the directors of Akron has entered into a voting agreement with CNB requiring each of them to vote all shares of Akron common stock owned by such director in favor of approval of the merger agreement. As of the record date, these directors held                  shares of Akron common stock, which represented approximately     % of the outstanding shares of Akron common stock.

Q: When and where is the Akron special meeting?

A: The special meeting of shareholders of Akron will be held at                on                 , at                 , local time.

Q: What will happen at the Akron special meeting?

A: At the special meeting, Akron shareholders will consider and vote upon the proposal to approve the merger agreement. If, at the time of the Akron special meeting, there are not sufficient votes for the shareholders to approve the merger agreement, you may be asked to consider and vote upon a proposal to adjourn such special meeting, so that additional proxies may be collected.

Q: Who is entitled to vote at the Akron special meeting?

A: All holders of Akron common stock who held shares at the close of business on                 , 2020, which is the record date for the special meeting of Akron shareholders, are entitled to receive notice of and to vote at the Akron special meeting. Each holder of Akron common stock is entitled to one vote for each share of Akron common stock owned as of the record date.

3

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

A: The quorum requirement for the Akron special meeting is the presence in person or by proxy of the holders of a majority of the total number of outstanding shares of Akron common stock entitled to vote.

Q: How does the board of directors of Akron recommend I vote?

A: After careful consideration, the Akron board of directors recommends that all of the Akron shareholders vote “FOR” approval of the merger agreement, and “FOR” the adjournment proposal, if necessary.

Q: Are there any risks that I should consider in deciding whether to vote for approval of the merger agreement?

A: Yes. You should read and carefully consider the risk factors set forth in the section in this proxy statement/prospectus entitled “Risk Factors” beginning on page 18 as well as the other information contained in or incorporated by reference into this proxy statement/prospectus, including the matters addressed in the section of this proxy statement/prospectus titled “Information Regarding Forward-Looking Statements” on page 26.

Q: What do I need to do now?

A: You should carefully read and consider the information contained in or incorporated by reference into this proxy statement/prospectus, including its annexes. It contains important information about the merger, the merger agreement, CNB and Akron. After you have read and considered this information, you should complete and sign your proxy card and return it in the enclosed postage-paid return envelope as soon as possible so that your shares will be represented and voted at the Akron special meeting.

Q: How may I vote my shares for the special meeting proposals presented in this proxy statement/prospectus?

A: You may vote by completing, signing, dating and returning the proxy card in the enclosed postage-paid envelope as soon as possible. This will enable your shares to be represented and voted at the Akron special meeting. You can also choose to attend the special meeting and vote your shares in person instead of completing and returning a proxy card.

Q: If my shares are held in “street name” by my broker, bank or other nominee, will my broker, bank or other nominee automatically vote my shares for me?

A: No. Your broker, bank or other nomineewill not vote your shares unless you provide instructions to your broker, bank or other nominee on how to vote. You should instruct your broker, bank or other nominee to vote your shares by following the instructions provided by the broker, bank or nominee with this proxy statement/prospectus.

Q: How will my shares be represented at the special meeting?

A: At the Akron special meeting, the officers named in your proxy card will vote your shares in the manner you requested if you properly signed and submitted your proxy. If you sign your proxy card and return it without indicating how you would like to vote your shares, your proxy will be voted as the Akron board of directors recommends, which is, (1) “FOR” the approval of the merger agreement and (2) “FOR” the approval of the adjournment of the special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to approve the merger agreement at the time of the special meeting.

4

Q: What if I fail to submit my proxy card or to instruct my broker, bank or other nominee?

A: If you fail to properly submit your proxy card or to instruct your broker, bank or other nominee to vote your shares Akron common stock and you do not attend the Akron special meeting and vote your shares in person, your shares will not be voted. This will have the same effect as a vote “AGAINST” approval of the merger agreement, but will have no impact on the outcome of the other proposal.

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

A: Yes. Although the Akron board of directors requests that you return the proxy card accompanying this proxy statement/prospectus, all Akron shareholders are invited to attend the special meeting. Shareholders of record on                 , can vote in person at the Akron special meeting. If your shares are held by a broker, bank or other nominee, then you are not the shareholder of record and you must bring to the special meeting appropriate documentation from your broker, bank or other nominee to enable you to vote at the special meeting.

Q: Can I change my vote after I have submitted my proxy?

A: Yes. If you do not hold your shares in “street name,” there are three ways you can change your vote at any time after you have submitted your proxy and before your proxy is voted at the special meeting:

• you may deliver a written notice bearing a date later than the date of your proxy card to Akron’s Secretary at the address listed below, stating that you revoke your proxy;

• you may submit a new signed proxy card bearing a later date (any earlier proxies will be revoked automatically); or

• you may attend the special meeting and vote in person, although attendance at the special meeting will not, by itself, revoke a proxy.

You should send any notice of revocation to Akron at:

A: The record date of the special meeting is earlier than the date of the special meeting and the date that the merger is expected to be completed. If you sell or otherwise transfer your shares after the record date for the Akron special meeting, but before the date of the Akron special meeting, you will retain your right to vote at the Akron special meeting, but you will not have the right to receive the merger consideration to be received by Akron’s shareholders in the merger.

Q: What do I do if I receive more than one proxy statement/prospectus or set of voting instructions?

A: If you hold shares directly as a record holder and also in “street name” or otherwise through a nominee, you may receive more than one proxy statement/prospectus and/or set of voting instructions relating to the special meeting. These should each be voted and/or returned separately in order to ensure that all of your shares are voted.

The Merger and the Merger Agreement

The proposed merger is of Akron with and into CNB Bank, with CNB Bank as the surviving entity in the merger. The merger agreement is attached to this proxy statement/prospectus asAnnex A. Please carefully read the merger agreement as it is the legal document that governs the merger.

Structure of the Merger (Page 60)

Subject to the terms and conditions of the merger agreement, and in accordance with the Pennsylvania Banking Code of 1965, as amended, or the PBC, and the New York Banking Law, as amended, or the NYBL, at the completion of the merger, Akron will merge with and into CNB Bank, a wholly-owned subsidiary of CNB. CNB Bank will be the surviving corporation in the merger and will continue its corporate existence under the laws of the Commonwealth of Pennsylvania. Upon completion of the merger, the separate corporate existence of Akron will terminate.

Consideration to be Received in the Merger(Page 61)

Cash or Stock Consideration. The merger agreement provides that Akron shareholders will have the right, with respect to each of their shares of Akron common stock, to elect to receive, subject to proration as described below, either (i) $215.00 in cash, without interest, or (ii) 6.6729 shares of CNB common stock. You will have the opportunity to elect the form of consideration to be received for each of your shares, subject to proration and allocation procedures set forth in the merger agreement, which may result in your receiving a portion of the merger consideration in a form other than that which you elected.

The value of the stock consideration is dependent upon the value of CNB common stock and, therefore, will fluctuate with the market price of CNB common stock. Accordingly, any change in the price of CNB common stock prior to the merger will affect the market value of any stock consideration that Akron shareholders will receive as a result of the merger.

No fractional shares of CNB common stock will be issued to any holder of Akron common stock upon completion of the merger. For each fractional share that would otherwise be issued, CNB will pay each shareholder cash (without interest) in an amount equal to the fractional share interest to which such shareholder would otherwise be entitled multiplied by the average of the daily closing prices of CNB common stock during the regular session of CNB common stock on the NASDAQ Global Select Market for the ten consecutive trading days immediately preceding, but not including, the trading day prior to the closing date of the merger.

Election Procedures for Shareholders(Page 62)

If you own Akron common stock, you will soon receive under separate cover an election form that you may use to indicate whether your preference is to receive cash or shares of CNB common stock. The election deadline will be 5:00 p.m., New York City time, on                     , 2020, the day prior to the date of the special meeting. To make an election, a holder must submit a properly completed election form and return it so that the form is actually received by American Stock Transfer & Trust Company, LLC at or before the election deadline in accordance with the instructions on the election form.

Non-Electing Akron Shareholders(Page 61)

Akron shareholders who make no election to receive cash or CNB common stock in the merger or who do not make a valid election will be deemed not to have made an election. Shareholders not making an election will be paid in CNB common stock.

Proration(Page 61)

The maximum number of shares of Akron common stock to be converted into cash consideration in the merger will be 25% of the outstanding shares of Akron common stock (including any shares for which dissenters’ rights are appropriately exercised but excluding shares of Akron common stock to be canceled in accordance with terms of the merger agreement). The remaining shares of Akron common stock will be converted into shares of CNB common stock. Therefore, elections are subject to certain proration and other provisions to preserve this requirement regarding the maximum number of shares of Akron common stock to be converted into cash in the merger.

If the Akron shareholders’ election and the number of shares of Akron common stock for which dissenters’ rights are appropriately exercised would result in more than 25% of the outstanding shares of Akron common stock (including any shares for which dissenters’ rights are appropriately exercised but excluding shares of Akron common stock to be canceled in accordance with terms of the merger agreement) being exchanged for cash, then all Akron shareholders who elected to receive stock consideration or who did not make an election will receive stock consideration, and all shareholders who have elected to receive cash consideration will receive the following:

• a number of shares of CNB common stock (rounded to the nearest whole share) equal to the product obtained by multiplying (i) the number of shares for which such shareholder made elections to receive the cash consideration and (ii) a fraction, the numerator of which is the amount by which (a) the sum of the number of shares for which all Akron shareholders made elections to receive cash consideration and the number of shares of Akron common stock for which dissenters’ rights are appropriately exercised exceeds (b) the maximum number of shares of Akron common stock to be converted into cash consideration, and the denominator of which is the number of shares for which elections were made to receive the cash consideration, and

• the right to receive cash consideration for the remaining number of such shareholder’s shares.

If the Akron shareholders’ elections and the number of shares of Akron common stock for which dissenters’ rights are appropriately exercised would result in 25% or fewer of the outstanding shares of Akron common stock (including any shares for which dissenters’ rights are appropriately exercised but excluding shares of Akron common stock to be canceled in accordance with terms of the merger agreement) being exchanged for cash, then all Akron shareholders who elected to receive cash consideration will receive cash consideration and all Akron shareholders who elected to receive stock consideration or made no election will receive stock consideration.

10

Surrender of Stock Certificates(Page 62)

Following the effective time of the merger, owners of Akron common stock will receive under separate cover a letter of transmittal, together with instructions for the exchange of their Akron common stock certificates for the merger consideration. Upon surrendering your certificate(s) representing shares of Akron’s common stock, together with the signed letter of transmittal, you shall be entitled to receive, as applicable (i) certificate(s) representing a number of whole shares of CNB’s common stock determined in accordance with the exchange ratio, (ii) a check representing the amount of cash to which you shall have become entitled to, and (iii) a check representing the amount of cash in lieu of fractional shares.

Material U.S. Federal Income Tax Consequences of the Merger(Page 54)

The merger is intended to qualify for U.S. federal income tax purposes as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, or the Code. Therefore, for U.S. federal income tax purposes, as a result of the merger, it is expected that a U.S. holder of shares of Akron common stock generally will only recognize gain (but not loss) in an amount not to exceed the cash (if any) received as part of the merger consideration and will recognize gain or loss if such holder received its consideration solely in cash or with respect to any cash received in lieu of fractional shares of CNB common stock.

Akron shareholders are urged to read the discussion in the section entitled “Material U.S. Federal Income Tax Consequences of the Merger” beginning on page54 and to consult their tax advisors for a full explanation of the tax consequences of the merger.

Recommendation of the Akron Board of Directors(Page 39)

After careful consideration of the various factors, including those set forth under the headings “The Merger—Akron’s Reasons for the Merger” and “The Merger—Recommendation of Akron’s Board of Directors” beginning on page 39, the Akron board of directors has determined that the merger agreement, the merger and the transactions contemplated by the merger agreement are advisable, fair to, and in the best interests of Akron and its shareholders. Accordingly, the Akron Board of Directors recommends that Akron shareholders vote:

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

• “FOR” the proposal to approve adjournments or postponements of the special meeting, if necessary, to permit further solicitation of proxies in favor of the foregoing proposal.

The merger is not conditioned on the proposal to approve adjournments or postponements of the special meeting.

Dissenters’ Appraisal Rights(Page 58)

Under New York law, you are entitled to dissenters’ rights of appraisal in connection with the merger, provided that you meet all of the conditions set forth in Section 6022 of the NYBL.

In particular, under New York law, appraisal rights are only available if, among other things, you are a record holder of shares as of the record date for the Akron special meeting, you do not vote your shares in favor of the proposal to approve the merger agreement at the Akron special meeting and you make a written demand upon Akron for the fair cash value of your shares of Akron common stock. If you are considering demanding payment of the fair cash value of your shares, you should note that the fair value of your shares determined under Section 6022 of the NYBL could be more than, the same as, or less than the consideration you would receive under the terms of the merger agreement if you did not demand payment of the fair value of your shares of Akron common stock.

11

To exercise appraisal rights, you must follow the strict procedures prescribed by Section 6022 of the New York Banking Law. For additional information, please see the section titled “The Merger—Dissenters’ Appraisal Rights” beginning on page 58. In addition, the full text of Section 6022 of the New York Banking Law is included asAnnex B to this proxy statement/prospectus.

Opinion of Akron’s Financial Advisor(Page 39)

Piper Sandler & Co. (“Piper Sandler”) acted as financial advisor to Akron’s board of directors in connection with the proposed merger and participated in certain of the negotiations leading to the execution of the merger agreement. At the December 18, 2019 meeting at which Akron’s board of directors considered the merger and the merger agreement, Piper Sandler delivered to the board of directors its oral opinion, which was subsequently confirmed in writing on December 18, 2019, to the effect that, as of such date, the merger consideration was fair to the holders of Akron common stock from a financial point of view.The full text of Piper Sandler’s opinion is attached as Annex C to this proxy statement/prospectus. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler 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 Akron common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

Piper Sandler’s opinion was directed to the board of directors of Akron in connection with its consideration of the merger and the merger agreement and does not constitute a recommendation to any shareholder of Akron as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the merger and the merger agreement. Piper Sandler’s opinion was directed only to the fairness, from a financial point of view, of the merger consideration to the holders of Akron common stock and did not address the underlying business decision of Akron 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 Akron or the effect of any other transaction in which Akron might engage.

Interests of Akron’s Directors and Executive Officers in the Merger(Page 52)

In considering Akron’s board of directors’ recommendation to vote in favor of the merger agreement proposal, you should be aware that Akron’s executive officers and directors have interests in the merger that may be different from, or in addition to, the interests of Akron shareholders generally. These interests include certain payments and benefits that may be provided to certain directors and executive officers of Akron, including (i) employment opportunities with the combined company, (ii) cash payments at closing pursuant to settlement agreements, (iii) cash payments pursuant to existing employment or severance agreements or (iv) continuation of indemnification and insurance coverage (for officers and directors) provided by CNB for a limited time after the merger. These interests also include the appointment, as of the effective time of the merger, of one officer or director of Akron (selected by CNB in consultation with Akron) to the Advisory Board of CNB Bank who will be paid a fee for each Advisory Board meeting attended in an amount consistent with the amount paid by CNB Bank to members of its currently existing Advisory Board. This per meeting amount is currently $450, paid in shares of CNB common stock.

12

As discussed in more detail in “The Merger—Interests of Akron Directors and Executive Officers in the Merger” beginning on page 52, the following table summarizes the interests of Akron’s directors and executive officers:

	Cash Payments under Settlement Agreements(1)		Cash Payments under Existing Agreements(2)
Anthony J. Delmonte, Jr	$	—	$	438,780
Kimberly Gromoll	$	30,000	$	—
Richard Johnson	$	60,000	$	—
Michelle Maloney	$	75,000	$	—
Stephen Mulé	$	75,000	$	—
Joseph M. Ondesko	$	—	$	169,950
Kristine K. Starke	$	60,000	$	—

(1) This column sets forth thelump-sum cash amount (determined prior to reduction for applicable tax withholdings) to be paid to the following executives pursuant to the settlement agreements.

(2) This column sets forth payments required to be paid to the following executives pursuant to existing employment or severance agreements.

After the closing of the merger between Akron and CNB Bank, it is expected that Anthony Delmonte will serve as Market Executive within CNB Bank’s BankOnBuffalo division.

Akron’s board of directors was aware of these interests and considered them, among other matters, when it approved the merger agreement and the merger and the other transactions contemplated thereby. For more information see “The Merger—Interests of Akron Directors and Executive Officers in the Merger” beginning on page 52.

CNB’s and CNB Bank’s Board of Directors After the Merger(Page 61)

The directors of CNB Bank immediately prior to the effective time of the merger will be the directors of CNB Bank immediately following the effective time of the merger.

No Solicitation of Alternative Transactions(Page 68)

The merger agreement restricts Akron’s ability to solicit or engage in discussions or negotiations with a third party regarding a proposal to acquire a significant interest in Akron. However, if Akron receives a bona fide unsolicited written acquisition proposal from a third party that is, or is reasonably likely to be, more favorable to Akron shareholders than the terms of the merger agreement, Akron may furnish nonpublic information to that third party and engage in negotiations regarding an acquisition proposal with that third party, subject to specified conditions in the merger agreement. In addition, while the Merger Agreement is in effect, the Akron board of directors may not:

• modify, qualify, amend or withdraw its approval or recommendation of the merger agreement;

• approve or recommend another acquisition proposal to its shareholders; or

• cause Akron to enter into a letter of intent or definitive agreement with respect to an acquisition transaction or that requires Akron to abandon, terminate or fail to consummate the merger.

However, the Akron board of directors may modify, qualify, amend or withdraw its recommendation of the merger agreement if it determines in good faith, after consultation with counsel and a financial advisor, that a bona fide unsolicited written acquisition proposal is a superior proposal and, after consultation with counsel, that

13

it is required to take such action to comply with its fiduciary duties to shareholders under applicable law. In that event, Akron must provide CNB with notice of such determination and cooperate and negotiate in good faith with CNB to adjust or modify the terms and conditions of the merger agreement.

Conditions to Completion of the Merger(Page 73)

As more fully described in this proxy statement/prospectus and the merger agreement, the completion of the merger depends on a number of conditions being satisfied or waived, including:

• two-thirds of the Akron shareholders must approve the merger agreement;

• CNB and Akron must have obtained all regulatory approvals required to consummate the transactions contemplated by the merger agreement, all related statutory waiting periods must have expired, and none of the regulatory approvals shall have imposed any term, condition or restriction that would prohibit or materially limit the ownership or operation by Akron or CNB of all or any material portion of the business or assets of Akron or CNB, or compel CNB to dispose of or hold separate all or any material portion of the business or assets of Akron or CNB, which we refer to in this proxy statement/prospectus as a burdensome condition;

• the registration statement must be effective;

• the absence of any order, decree or injunction in effect, or any law, statute or regulation enacted or adopted, that enjoins, prohibits, materially restricts or makes illegal the consummation of the transactions contemplated by the merger agreement;

• CNB and Akron must each receive a legal opinion from their respective counsel regarding treatment of the merger as a “reorganization” for federal income tax purposes;

• the representations and warranties of each of CNB and Akron in the merger agreement must be accurate, subject to exceptions that would not have a material adverse effect; and

• CNB and Akron must each have performed in all material respects all obligations required to be performed by it.

Termination of the Merger Agreement(Page 75)

CNB and Akron can mutually agree to terminate the merger agreement before the merger has been completed, and either company can terminate the merger agreement if:

• the merger is not consummated by September 30, 2020, unless the terminating party’s failure to comply with the merger agreement was the cause of the failure of the merger to occur on or before this date;

• the other party materially breaches any of its representations, warranties, covenants or other agreements contained in the merger agreement (provided that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained in the merger agreement), and the breach cannot be or has not been cured within 30 days of written notice of the breach and such breach would entitle thenon-breaching party not to consummate the transactions contemplated by the merger agreement;

• any regulatory approval required for consummation of the merger and the other transactions contemplated by the merger agreement has been denied by final nonappealable action of any regulatory authority, or any governmental authority has issued a final nonappealable order, injunction or decree enjoining or otherwise prohibiting the transactions contemplated by the merger agreement, provided

14

that the terminating party has used its reasonable best efforts to have the order, injunction or decree lifted; or

• the required approval of the merger agreement by the Akron shareholders is not obtained.

In addition, CNB may terminate the merger agreement if:

• the Akron board of directors:

• withdraws, qualifies, amends, modifies or withholds its recommendation to the Akron shareholders to vote in favor of the merger agreement or makes any statement, filing or release that is inconsistent with the recommendation;

• materially breaches its obligation to call, give notice of and commence the special meeting;

• approves or recommends another acquisition proposal;

• fails to publicly recommend against a publicly announced acquisition proposal within five business days of being requested to do so by CNB;

• fails to publicly reconfirm its recommendation to its shareholders to vote in favor of the merger agreement within five business days of being requested to do so by CNB, except during a period in which the Akron board of directors is evaluating an acquisition proposal to comply with its fiduciary duties to Akron shareholders under applicable law; or

• resolves or otherwise determines to take, or announces an intention to take, any of the actions listed above; or

• Akron breaches in any material respect the provisions in the merger agreement prohibiting the solicitation of other offers.

In addition, Akron has the right to terminate the merger agreement if the average closing price of CNB common stock for a specified period prior to closing is less than $25.77 and CNB common stock underperforms a specified peer-group index by more than 20%. However, CNB will have the option to increase the amount of CNB common stock to be provided to Akron shareholders, in which case no termination will occur.

Termination Fee(Page 76)

Akron has agreed to pay to CNB a termination fee of $2.5 million if:

• CNB terminates the merger agreement as a result of the Akron board of directors:

• withdrawing, qualifying, amending, modifying or withholding its recommendation to the Akron shareholders to vote in favor of the merger agreement or making any statement, filing or release that is inconsistent with the recommendation;

• materially breaching its obligation to call, give notice of and commence the special meeting;

• approving or recommending another acquisition proposal;

• failing to publicly recommend against a publicly announced acquisition proposal within five business days of being requested to do so by CNB;

• failing to publicly reconfirm its recommendation to its shareholders to vote in favor of the merger agreement within five business days of being requested to do so by CNB; or

• resolving or otherwise determining to take, or announcing an intention to take, any of the actions listed above; or

15

• CNB terminates the merger agreement as a result of a material breach by Akron of the provisions in the merger agreement prohibiting the solicitation of other offers.

Akron has further agreed to pay to CNB a termination fee of $2.5 million if:

• CNB or Akron terminates the merger agreement as a result of a breach by Akron of any of its representations, warranties, covenants or agreements contained in the merger agreement and:

• the failure oftwo-thirds of the Akron shareholders to approve the merger agreement, or the merger not having been consummated by September 30, 2020, due to the failure of Akron shareholders to approve the merger agreement, and an acquisition proposal with respect to Akron has been publicly announced, disclosed or otherwise communicated to the Akron board of directors or senior management of Akron prior to September 30, 2020, or prior to the special meeting, as applicable; and

• within 12 months of termination of the merger agreement, Akron recommends to its shareholders another acquisition proposal or enters into a definitive agreement with respect to, or consummates, another acquisition transaction; or

Akron has also agreed to pay to CNB a termination fee of $2.5 million if:

• CNB terminates the merger agreement as a result of:

• an acquisition proposal with respect to Akron has been publicly announced, disclosed or otherwise communicated to the Akron board of directors or senior management of Akron prior to such breach or during the related cure period; and

• within 12 months of termination of the merger agreement, Akron recommends to its shareholders an acquisition proposal or enters into a definitive agreement with respect to, or consummates, an acquisition transaction.

CNB has agreed to pay to Akron a termination fee of $1.25 million if:

• CNB or Akron terminates the merger agreement as a result of the merger not having been consummated by September 30, 2020, unless the terminating party’s failure to comply with the merger agreement was the cause of the failure of the merger to occur on or before this date; and

• all regulatory approvals required for consummation of the merger and the other transactions contemplated by the merger agreement have not been obtained.

Waiver or Amendment of Merger Agreement Provisions(Page 77)

At any time prior to the completion of the merger, a provision of the merger agreement may be waived by the party intended to benefit by the provision, or may be amended or modified by a written action taken or authorized by the parties’ respective boards of directors. However, after the approval of the merger agreement bytwo-thirds of the Akron shareholders, no amendment will be made which by law requires further approval by Akron shareholders without such further approval.

Regulatory Approvals Required for the Merger(Page 57)

Approval by the Federal Deposit Insurance Corporation, or FDIC, and the Pennsylvania Department of Banking and Securities, or PADOBS, is required prior to the merger of Akron into CNB Bank. The United States Department of Justice is able to provide input into the approval process of federal banking agencies to challenge any approval on antitrust grounds. CNB and Akron cannot predict, however, whether or when the required regulatory approvals will be obtained or whether any such approvals will impose any burdensome condition upon CNB or CNB Bank.

16

Accounting Treatment of the Merger(Page 58)

The merger will be accounted for using the purchase method of accounting with CNB treated as the acquiror. Under this method of accounting, Akron’s assets and liabilities will be recorded by CNB at their respective fair values as of the closing date of the merger and added to those of CNB. The excess of purchase price over the net fair values of Akron’s assets and liabilities will be recorded as goodwill. The excess of the fair value of Akron’s net assets over the purchase price, if any, will be recognized in earnings by CNB on the closing date of the merger.

Listing of CNB Common Stock to be Issued in the Merger

CNB is a Pennsylvania corporation and Akron is a New York-chartered bank. The CNB articles of incorporation andby-laws contain provisions that are different from the Akron organization certificate andby-laws. Upon completion of the merger, Akron shareholders who receive stock consideration in the merger will become shareholders of CNB, and their rights will be governed by the Pennsylvania Banking Code of 1965, as amended, and CNB’s articles of incorporation andby-laws. No change to CNB’s articles of incorporation orby-laws will be made as a result of the completion of the merger. For a discussion of certain differences among the rights of CNB shareholders and Akron shareholders, see “Comparison of Shareholder Rights” beginning on page 79.

RISK FACTORS

In addition to the other information contained in or incorporated by reference into this joint proxy statement/prospectus, including the matters addressed under the caption “Information Regarding Forward-Looking Statements” on page26, you should carefully consider the following risk factors in deciding whether to vote for approval of the merger agreement.

The value of the merger consideration will vary with changes in CNB’s stock price.

Upon completion of the merger, each share of Akron common stock, other than dissenting shares, will be converted into the right to receive merger consideration consisting of, at the option of the holder of such share, either cash or shares of CNB common stock. Because the per share stock consideration is fixed at 6.6729 shares of CNB common stock, the market value of the CNB common stock to be issued in the merger will depend upon the market price of CNB common stock. This market price may vary from the closing price of CNB common stock on the date the merger was announced, on the date that this proxy statement/prospectus was mailed to Akron shareholders and on the date of the Akron special meeting. Accordingly, Akron shareholders who elect to receive stock consideration will not necessarily know or be able to calculate the value of the stock consideration they would be entitled to receive upon completion of the merger.

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

The businesses of CNB and Akron differ and, accordingly, the results of operations of the combined company and the market price of the combined company’s shares of common stock may be affected by factors different from those currently affecting the independent results of operations and market prices of common stock of each of CNB and Akron. For a discussion of the businesses of CNB and Akron and, in the case of CNB, of certain factors to consider in connection with those businesses, see “Information About the Companies” beginning on page 28 and the documents incorporated by reference in this proxy statement/prospectus and referred to under “Where You Can Find More Information” beginning on page 88.

Akron shareholders may receive a form of consideration different from what they elect.

While each Akron shareholder may elect to receive cash or CNB common stock in the merger, no more than 25% of Akron common stock outstanding at the completion of the merger will be converted into cash. Therefore, if Akron shareholders elect more cash than is available under the merger agreement, their elections will be prorated to permit 75% of Akron common stock outstanding at the completion of the merger to be converted into CNB common stock. As a result, your ability to receive cash in accordance with your election may depend on the elections of other Akron shareholders.

The merger agreement may not be completed if certain conditions to the merger are not satisfied or waived or if the merger agreement is terminated by the parties in accordance with its terms.

The merger agreement is subject to a number of conditions which must be fulfilled in order to complete the merger. Those conditions include:

• approval of the merger agreement bytwo-thirds of the Akron shareholders;

• the receipt of required 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;

• the continued accuracy of the representations and warranties by both parties and the performance by both parties of their covenants and agreements; and

• the receipt by both parties of legal opinions from their respective tax counsels.

18

In addition, Akron has the right to terminate the merger agreement if the average closing price of CNB common stock for a specified period prior to closing is less than $25.77 and CNB common stock underperforms a specified peer-group index by more than 20%. However, CNB will have the option to increase the amount of CNB common stock to be provided to Akron shareholders, in which case no termination will occur. See the section of this proxy statement/prospectus titled “The Merger Agreement—Termination of the Merger Agreement” beginning on page 75 for a more complete discussion of the circumstances under which the merger agreement could be terminated.

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

Before the merger may be completed, various approvals or consents must be obtained from state and federal governmental authorities, including the FDIC and the PADOBS. Satisfying any requirements of these regulatory agencies may delay the date of completion of the merger. In addition, 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. Any regulatory restriction may diminish the benefits of the merger to CNB. CNB is not required to complete the merger if a governmental agency, as part of its authorization or approval, imposes any term, condition or restriction upon CNB or its subsidiaries that, in CNB’s reasonable determination, would prohibit or materially limit the ownership or operation by CNB of any material portion of Akron’s or CNB’s business or assets, or that would compel CNB to dispose or hold separate any material portion of Akron’s or CNB’s assets.

If the merger is not completed, Akron will have incurred substantial expenses without its shareholders realizing the expected benefits.

Akron has incurred substantial expenses in connection with the transactions described in this proxy statement/prospectus. If the merger is not completed, Akron expects that it will have incurred approximately $400,000.00 in merger-related expenses, excluding any termination fee that may be due to CNB under the merger agreement. See the section of this proxy statement/prospectus titled “The Merger Agreement–Termination Fee” beginning on page 76 for a discussion of the termination fee. These expenses would likely have a material adverse impact on the operating results of Akron because it would not have realized the expected benefits of the merger. There can be no assurance that the merger will be completed.

Akron’s directors and executive officers have financial interests in the merger that may be different from, or in addition to, the interests of Akron shareholders.

In considering the information contained in this proxy statement/prospectus, you should be aware that Akron’s executive officers and directors have financial interests in the merger that are different from, or in addition to, the interests of Akron shareholders generally. These interests include, among other things:

• the right to receive payments under certain settlement agreements;

• the right to continued indemnification and liability insurance coverage by CNB after the merger for acts or omissions occurring before the merger; and

• in the case of one officer or director of Akron, a seat on the Advisory Board of CNB Bank, and any related compensation for such services, if applicable.

• in the case of Anthony J. Delmonte, Jr., a position as Market Executive within CNB’s BankOnBuffalo division.

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

Uncertainty about the effect of the merger on employees, suppliers and customers may have an adverse effect on Akron. These uncertainties may impair Akron’s ability to attract, retain and motivate key personnel until the

19

merger is completed, and could cause customers, suppliers and others who deal with Akron to seek to change existing business relationships with Akron. Akron employee retention and recruitment may be particularly challenging prior to the effective time of the merger, as employees and prospective employees may experience uncertainty about their future roles with the combined company.

The pursuit of the merger and the preparation for the integration may place a significant burden on management and internal resources. Any significant diversion of management attention away from ongoing business and any difficulties encountered in the transition and integration process could affect the financial results of Akron and, following the merger, the combined company. In addition, the merger agreement requires that Akron operate in the ordinary course of business consistent with past practice and restricts Akron from taking certain actions prior to the effective time of the merger or termination of the merger agreement without the prior written consent of CNB. These restrictions may prevent Akron from pursuing attractive business opportunities that may arise prior to the completion of the merger.

The termination fee and the restrictions on solicitation contained in the merger agreement may discourage other companies from trying to acquire Akron.

Until the completion of the merger, Akron is prohibited from soliciting, initiating, encouraging, or with some exceptions, considering any inquiries or proposals that may lead to a proposal or offer for a merger or other business combination transaction with any person other than CNB. In addition, Akron has agreed to pay a termination fee of $2.5 million to CNB in specified circumstances. These provisions could discourage other companies from trying to acquire Akron even though those other companies might be willing to offer greater value to Akron shareholders than CNB has offered in the merger. The payment of the termination fee also could have a material adverse effect on Akron’s results of operations.

The fairness opinion obtained by Akron from its financial advisor will not reflect changes in circumstances subsequent to the date of the fairness opinion.

Piper Sandler, Akron’s financial advisor in connection with the proposed merger, orally delivered to the board of directors of Akron its opinion, which was subsequently confirmed in writing, dated as of December 18, 2019, to the effect that, as of such date and based upon and subject to the factors, qualifications and assumptions set forth therein, the merger consideration set forth in the merger agreement was fair to the holders of Akron common stock from a financial point of view. Because Akron does not currently anticipate asking Piper Sandler to update its opinion, the opinion will not address the fairness of the merger consideration from a financial point of view at the time the merger is completed. Accordingly, the opinion does not reflect changes that may occur or may have occurred after the date of the opinion, including changes to the operations and prospects of CNB or Akron, changes in general market and economic conditions or regulatory or other factors which may be beyond the control of CNB and Akron. Any such changes, or changes in other factors on which the opinion was based, may materially alter or affect the relative values of CNB or Akron.

CNB may fail to realize the anticipated benefits of the merger.

The success of the merger will depend on, among other things, CNB’s ability to realize anticipated cost savings and to combine the businesses of CNB and Akron in a manner that does not materially disrupt the existing customer relationships of Akron nor result in decreased revenues from any loss of customers. The success of the merger will also depend upon the integration of employees, systems, operating procedures and information technologies, as well as the retention of key employees. Additionally, the success of the merger is to an extent dependent upon Akron customers choosing to continue their relationships with the combined company following the consummation of the transaction, despite that the Akron franchise will no longer be locally owned. If CNB is not able to successfully achieve its objectives, or if Akron customers choose not to continue their relationships with the combined company, the anticipated benefits of the merger may not be realized fully or at all or may take longer to realize than expected.

20

CNB and Akron have operated and, until the completion of the merger, will continue to operate, independently. It is possible that the integration process could result in the loss of key employees, the disruption of Akron’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the ability of CNB to maintain relationships with customers and employees or to achieve the anticipated benefits of the merger.

Unanticipated costs relating to the merger could reduce CNB’s future earnings per share.

CNB believes that it has reasonably estimated the likely costs of integrating the operations of CNB and Akron, and the incremental costs of operating as a combined company. However, it is possible that unexpected transaction costs such as taxes, fees or professional expenses or unexpected future operating expenses such as increased personnel costs or increased taxes, as well as other types of unanticipated adverse developments, could have a material adverse effect on the results of operations and financial condition of the combined company. If unexpected costs are incurred, the merger could have a dilutive effect on the combined company’s earnings per share. In other words, if the merger is completed, the earnings per share of CNB common stock could be less than they would have been if the merger had not been completed.

After the merger is completed, Akron shareholders will become CNB shareholders and will have different rights that may be less advantageous than their current rights.

Upon completion of the merger, Akron shareholders will become CNB shareholders. Differences in Akron’s organization certificate andby-laws and CNB’s articles of incorporation andby-laws will result in changes to the rights of Akron shareholders who become CNB shareholders. For more information, see “Comparison of Shareholder Rights,” beginning on page 79 of this document.

Both Akron and CNB shareholders will have a reduced ownership and voting interest after the merger and will exercise less influence over management of the combined organization.

Akron shareholders currently have the right to vote in the election of the board of directors of Akron and on various other matters affecting Akron. After the merger, each Akron shareholder will hold a percentage ownership of the combined organization that is much smaller than such shareholder’s current percentage ownership of Akron. It is expected that the former shareholders of Akron as a group will receive shares in the merger constituting less than approximately 9% of the outstanding shares of CNB common stock immediately after the merger. Because of this, Akron’s shareholders will have significantly less influence on the management and policies of CNB than they now have on the management and policies of Akron. Additionally, CNB’s shareholders will have less influence on the management and policies of CNB than they now have on the management and policies of CNB.

The tax consequences of the merger to an Akron shareholder will be dependent upon the merger consideration received.

The merger is intended to qualify for U.S. federal income tax purposes as a “reorganization” within the meaning of Section 368(a) of the Code. Therefore, for U.S. federal income tax purposes, as a result of the merger, it is expected that a U.S. holder of shares of Akron common stock generally will only recognize gain (but not loss) in an amount not to exceed the cash (if any) received as part of the merger consideration and will recognize gain or loss if such holder received the entirety of its consideration in cash or with respect to any cash received in lieu of fractional shares of CNB common stock.

The market value of the CNB common stock to be issued in exchange for shares of Akron common stock upon the completion of the merger will not be known at the time of the Akron special meeting. The above tables show only historical comparisons. Because the market prices of CNB common stock and Akron common stock will likely fluctuate prior to the merger, these comparisons may not provide meaningful information to Akron shareholders in determining whether to approve the merger agreement. Akron shareholders are encouraged to obtain current market quotations for CNB common stock and Akron common stock and to review carefully the other information contained in this proxy statement/prospectus or incorporated by reference in this proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 88.

The holders of CNB common stock receive dividends as and when declared by CNB’s board of directors out of statutory surplus or from net profits. Following the completion of the merger, subject to approval and declaration by CNB’s board of directors, CNB expects to continue paying quarterly cash dividends on a basis consistent with past practice. The current annualized rate of distribution on a share of CNB common stock is $0.68 per share. However, the payment of dividends by CNB is subject to numerous factors, and no assurance can be given that CNB will pay dividends following the completion of the merger or that dividends will not be reduced in the future.

The merger agreement permits Akron to continue to pay regular quarterly cash dividends with record and payment dates consistent with past practice prior to completion of the merger.

The Akron board of directors has approved the merger agreement and recommends that you vote your shares as follows:

• “FOR” approval of the merger agreement; and

• “FOR” the proposal to adjourn the special meeting, if necessary, to permit further solicitation of proxies.

Akron will include proxies marked as abstentions and brokernon-votes in determining the number of shares present at the special meeting.

Akron, NY 14001

Attention: Jessica Brandi

(716)542-5401

If you hold your shares of Akron common stock in “street name,” meaning in the name of a bank, broker or other nominee who is the record holder, you must either direct the record holder of your shares of Akron common stock how to vote your shares or obtain a proxy from the record holder to vote your shares in person at the special meeting.

If you fail to properly submit your proxy card or to instruct your broker, bank or other nominee to vote your shares of Akron common stock and you do not attend the special meeting and vote your shares in person, your shares will not be voted. This will have the same effect as a vote “AGAINST” approval of the merger agreement.

How to Revoke Your Proxy

If you are an Akron shareholder, you may revoke your proxy at any time by taking any of the following actions before your proxy is voted at the special meeting:

• delivering a written notice bearing a date later than the date of your proxy card to the Secretary of Akron, stating that you revoke your proxy;

31

• submitting a new signed proxy card bearing a later date (any earlier proxies will be revoked automatically); or

• attending the special meeting and voting in person, although attendance at the special meeting will not, by itself, revoke a proxy.

You should send any notice of revocation to Jessica Brandi, Secretary, at the following address:

Bank of Akron

P.O. Box 358

Akron, NY 14001

If you have instructed a bank, broker or other nominee to vote your shares, you must follow the directions you receive from your bank, broker or other nominee to change your vote.

Voting in Person

If you are an Akron shareholder and plan to attend the Akron special meeting and wish to vote in person, you will be given a ballot at the special meeting. Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to vote at the special meeting, you must obtain a proxy from the broker, bank or other nominee in order to vote your shares.

Whether or not you plan to attend the special meeting, Akron requests that you complete, sign, date and return the enclosed proxy card as soon as possible in the enclosed postage-paid envelope. This will not prevent you from voting in person at the special meeting but will assure that your vote is counted if you are unable to attend.

Abstentions and BrokerNon-Votes

Only shares affirmatively voted for approval of the merger agreement, including shares represented by properly executed proxies that do not contain voting instructions, will be counted as votes “FOR” approval of the merger agreement and “FOR” approval of the proposal to adjourn the special meeting.

Brokers who hold shares of Akron common stock in street name for a customer who is the beneficial owner of those shares may not exercise voting authority on the customer’s shares with respect to the actions proposed in this document without specific instructions from the customer. Proxies submitted by a broker that do not exercise this voting authority are referred to as brokernon-votes. If your broker holds your Akron stock in street name, your broker will vote your shares only if you provide instructions on how to vote by filling out the voter instruction form sent to you by your broker with this document.

Accordingly, you are urged to mark and return the enclosed proxy card to indicate your vote, or fill out the voter instruction form, if applicable.

Abstentions and brokernon-votes will be included in determining the presence of a quorum at the special meeting. Abstentions and brokernon-votes will have the same effect as voting “AGAINST” the proposal to approve the merger agreement, but will have no effect on the other proposal.

Proxy Solicitation

If you are an Akron shareholder, the enclosed proxy is solicited by and on behalf of the Akron board of directors. Akron will pay the expenses of soliciting proxies to be voted at the special meeting, except that CNB has agreed to pay the costs of preparing, printing, filing and mailing this document, other than attorneys’ and accountants’

32

fees which will be paid by the party incurring the expense. Following the original mailing of the proxies and other soliciting materials, Akron and its agents also may solicit proxies by mail, telephone, facsimile or in person. No additional compensation will be paid to directors, officers or other employees of Akron for making these solicitations. Akron intends to reimburse persons who hold Akron common stock of record but not beneficially, such as brokers, custodians, nominees and fiduciaries, for their reasonable expenses in forwarding copies of proxies and other soliciting materials to, and requesting authority for the exercise of proxies from, the persons for whom they hold the shares.

This proxy statement/prospectus and the proxy card are first being sent to Akron shareholders on or about                      , 2020.

Stock Certificates

If you are an Akron shareholder, you should not send in any certificates representing Akron common stock. Following the completion of the merger, you will receive separate instructions for the exchange of your certificates representing Akron common stock.

Proposal to Approve Adjournment of the Special Meeting

Akron is also submitting a proposal for consideration at the special meeting to authorize the named proxies to approve one or more adjournments of the special meeting if there are not sufficient votes to approve the merger agreement at the time of the special meeting. Even though a quorum may be present at the special meeting, it is possible that Akron may not have received sufficient votes to approve the merger agreement by the time of the special meeting. In that event, Akron would need to adjourn the special meeting in order to solicit additional proxies. The adjournment proposal relates only to an adjournment of the special meeting for purposes of soliciting additional proxies to obtain the requisite shareholder approval to approve the merger agreement. If the special meeting is adjourned, Akron is not required to give notice of the time and place of the adjourned meeting unless the board of directors fixes a new record date for the special meeting.

The proposal to approve one or more adjournments of the special meeting requires the affirmative vote of a majority of those present in person or by proxy and entitled to vote on the proposal. The Akron board of directors retains full authority to the extent set forth in Akron’sby-laws and New York law to adjourn the special meeting for any other purpose, or to postpone the special meeting before it is convened, without the consent of any Akron shareholders.

PROPOSAL I—THE MERGER

The following discussion contains material information about the merger. The discussion is subject, and qualified in its entirety by reference, to the merger agreement and financial advisors’ opinions attached as annexes to this proxy statement/prospectus. We urge you to read carefully this entire proxy statement/prospectus, including the merger agreement and Akron’s financial advisor’s opinion attached as annexes to this proxy statement/prospectus, for a more complete understanding of the merger.

General

On December 18, 2019, the boards of directors of CNB, CNB Bank and Akron each approved the merger agreement. The merger agreement provides for the acquisition of Akron by CNB through a merger of Akron with and into CNB Bank, with CNB Bank as the surviving entity.

Upon completion of the merger, holders of Akron common stock (other than stock held by Akron or CNB) will be entitled to elect to receive, for each share of Akron common stock that is issued and outstanding, (i) $215.00 in cash, without interest, or (ii) 6.6729 shares of CNB common stock, subject to proration provisions described herein and set forth in the merger agreement.

See “The Merger Agreement,” beginning on page 60, for additional and more detailed information regarding the legal documents that govern the merger, including information about the conditions to the merger and the provisions for terminating or amending the merger agreement.

Background of the Merger

In an effort to better understand and address the current and future environment for community banking, the current and prospective opportunities for Akron in particular, and to plan for the future, the Akron board of directors has periodically consulted with financial and banking industry advisors. At a meeting of the Akron board of directors on November 15, 2017, the Akron board of directors invited representatives of Piper Sandler to discuss with the Akron board of directors the state of the community banking industry and the capital markets and to present strategic alternatives for Akron to increase shareholder value in light of the challenging business environment. Piper Sandler in its presentation to the Akron board of directors and the Akron management team discussed, among other things (i) an offering of Akron common stock in a dollar amount to permit significant future growth, (ii) a private investment in public equity transaction, (iii) a rights offering, and (iv) a merger or other similar transaction with a financial institution of similar or larger size. Piper Sandler’s presentation provided an overview of each of the strategic alternatives and their relative advantages and disadvantages.

After extensive discussion and consideration of the strategic alternatives available to Akron throughout 2017 and 2018, the Akron board of directors decided to request that Piper Sandler explore the possibility of a merger or other similar transaction with either asimilarly-sized or larger financial institution. In September 2019, the Akron board of directors authorized Akron’s management to engage Piper Sandler as an independent financial advisor to assist Akron in connection with a possible business combination. In connection with this engagement, Piper Sandler identified 13 financial institutions based on their relative size, geographic proximity to Akron’s market and Piper Sandler’s knowledge of the banking industry in such markets. Piper Sandler assisted the Akron board of directors in preparing a confidential information memorandum (“CIM”) regarding Akron, which was submitted to each of the 10 financial institutions that executed anon-disclosure agreement. Eachnon-disclosure agreement contained customary confidentiality provisions and standstill provisions prohibiting such financial institutions from engaging in certain types of actions, including making an acquisition proposal with respect to Akron without Akron’s prior written consent. Piper Sander received expressions of interest from five of the ten financial institutions that were sent CIMs (including CNB) in late September 2019.

On October 16, 2019, the Akron board of directors held a regularly-scheduled meeting, with representatives of Hodgson Russ and Piper Sandler present. During this meeting, the Akron board of directors discussed the

34

expressions of interest received. Following this discussion, two of the five expressions of interest were rejected, because among other reasons, they were not as financially favorable as the other three expressions of interest. The remaining three financial institutions, including CNB, were invited to submit second round offers.

Beginning approximately October 7 2019, each of the three financial institutions invited to submit second round offers conducted additional due diligence reviews of Akron, which included access to a secure data room.

On November 7, 2019 and November 8, 2019, members of the CNB management team, along with representatives of Hogan Lovells US LLP, CNB’s legal counsel, or Hogan Lovells, and Griffin Financial Group, CNB’s financial advisor, or Griffin Financial, conducted management interviews and participated in diligence meetings with representatives of Akron.

On November 15, 2019, second round expressions of interest were received from each of the three financial institutions that were invited to submit second round offers.

The offer from CNB contemplated that CNB would acquire 100% of the outstanding shares of common stock of Akron at a price of $215.00 per share (for total consideration of approximately $64.5 million, representing a market premium of 168% of tangible book value as of September 30, 2019), with at least 75% of the consideration being paid to Akron’s shareholders in the form of shares of CNB common stock. The pro forma annualized cash dividend based on the then-current Akron dividend indicated an anticipated increase of 60% in projected dividends for Akron shareholders. Among other things, the indication of interest also provided for the merger of Akron into CNB Bank, with CNB Bank being the surviving entity, the appointment of a representative from Akron to the local advisory board of CNB Bank, and operation of Akron as part of CNB Bank’s BankOnBuffalo division.

The offer from the second financial institution, referred to herein as Company B, provided for the acquisition of 100% of the outstanding shares of common stock of Akron at a price of $213.00 per share (for total consideration of approximately $63.9 million, representing a market premium of 166% of tangible book value as of September 30, 2019), with70-80% of the consideration being paid to Akron’s shareholders in the form of shares of Company B common stock. The indication of interest contemplated that Akron would be merged into Company B and that one of more members of the Akron board of directors would be appointed to the Company B board of directors.

The third offer, from a financial institution referred to herein as Company C, contemplated that Company C would acquire 100% of the outstanding shares of common stock of Akron at a price of $213.00 per share (for total consideration of approximately $63.9 million, representing a market premium of 166% of tangible book value as of September 30, 2019), with at least 65% of the consideration being paid to Akron’s shareholders in the form of shares of Company C common stock. Under the proposed transaction structure, Akron would merge into Company C as a wholly-owned banking subsidiary and representatives of Akron would be appointed to two seats on the Company C board of directors.

On November 20, 2019, the Akron board of directors held a regularly-scheduled meeting, with representatives of Piper Sandler present. During this meeting, the Akron board of directors discussed with representatives of Piper Sandler thenon-binding indications of interest provided by CNB, Company B, and Company C. After the discussion, the Akron board of directors concluded that, based on the information presented, the CNB proposal was more attractive than Company B’s proposal and Company C’s proposal because, among other reasons, the CNB proposal provided greater consideration for Akron’s shareholders as well as potentially better future prospects for Akron shareholders that would become shareholders of CNB. Representatives of Piper Sandler informed the Akron board of directors that they believed the terms of the CNB proposal would be fair to Akron shareholders from a financial perspective and that Piper Sandler would be able to issue a fairness opinion with respect to the proposed merger. At the conclusion of the discussion, the Akron board of directors authorized management to execute the CNBnon-binding indication of interest.

Following discussions between Anthony J. Delmonte, Jr., President and Chief Executive Officer of Akron and Joseph B. Bower, Jr., President and Chief Executive Officer of CNB, and Tito L. Lima, Executive Vice President and Chief Financial Officer of CNB, regarding these revisions and the agreement by CNB to a revised draft of thenon-binding indication of interest, Akron accepted CNB’snon-binding indication of interest and Akron and its representatives were provided access to a secure virtual data room containing due diligence materials andnon-public information about CNB.

Thereafter, and continuing throughout the negotiating process, CNB and representatives of CNB continued to conduct a due diligence review of Akron’s business, finances and operations. CNB made supplemental requests for due diligence materials, and representatives of the parties had numerous discussions with respect to matters raised in the course of the due diligence process.

On December 1, 2019, Hogan Lovells distributed an initial draft of the merger agreement to Akron’s legal advisor, Hodgson Russ, LLP, or Hodgson Russ. The proposed draft contemplated a merger of Akron with and into CNB Bank, with CNB Bank surviving the merger. The draft merger agreement provided for, among other things, customaryno-shop and fiduciary out provisions and a termination fee payable by Akron under certain circumstances equal to $2,750,000.

On December 9, 2019, Hogan Lovells transmitted initial drafts of the voting agreement pursuant to which certain directors of Akron would agree to vote their shares of Akron common stock in favor of the proposed merger and certain other ancillary documents, including employment and settlement agreements, to Akron’s advisors.

Also on December 9, 2019, representatives of Akron conductedon-site “reverse due diligence” of CNB and CNB Bank. As part of its review, Akron reviewed various CNB and CNB Bank documents that were requested by Akron and met with CNB’s management to discuss CNB’s business, results of operations and prospects. Akron also reviewed CNB’s publicly-available documents previously filed with the Securities and Exchange Commission and discussed CNB’s relationships with its bank regulators.

On December 10, 2019, Hodgson Russ transmitted a revised draft of the merger agreement to Hogan Lovells. The revised draft provided for, among other things, a termination fee payable by Akron equal to $2,000,000.

On December 11, 2019, Hogan Lovells distributed a revised draft of the merger agreement to Hodgson Russ. The revised draft provided for, among other things, a termination fee payable by Akron equal to $2,750,000.

On December 15, 2019, Anthony J. Delmonte, Jr., President and Chief Executive Officer of Akron and Stephen Forrestal, Chairman of the Akron board of directors met telephonically with Messrs. Bower and Lima, with representatives of Hodgson Russ, Hogan Lovells, Piper Sandler present and Griffin Financial attending via telephone. During this meeting, the parties discussed matters relating to regulatory approval of the merger.

On December 17, 2019, Hodgson Russ distributed a revised draft of the merger agreement to Hogan Lovells. The revised draft provided for, among other things, a termination fee payable by Akron equal to $2,500,000 and a termination fee payable by CNB in the event the merger agreement is terminated due to the failure to obtain all required regulatory approvals for the merger equal to $2,000,000.

Later on December 17, 2019, Messrs. Bower and Delmonte met telephonically to discuss the terms of the merger agreement. During this meeting, Messrs. Bower and Delmonte agreed that the amount of the termination fee payable by CNB would be equal to $1,250,000 and the amount of the termination fee payable by Akron would be equal to $2,500,000.

Also on December 17, 2019, Hogan Lovells distributed to Hodgson Russ a revised draft of the merger agreement. The revised draft reflected the terms of the merger agreement agreed to by Messrs. Bower and Delmonte.

On December 18, 2019, the Akron board of directors held a regularly-scheduled meeting, with representatives of Piper Sandler and Hodgson Russ present, to review and consider the proposed merger with CNB. Copies of the merger agreement and related materials were distributed to the members of the Akron board of directors in advance of the meeting. At the meeting, members of Akron’s senior executive management, together with representatives of Piper Sandler and Hodgson Russ, discussed the status of negotiations with CNB and presented to the Akron board of directors the material terms of the merger agreement. Representatives of Piper Sandler provided Piper Sandler’s financial analysis of the proposed merger and rendered Piper Sandler’s opinion to the Akron board of directors to the effect that, as of December 18, 2019 and subject to the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler in rendering its opinion, as set forth therein, the merger consideration set forth in the merger agreement was fair to the holders of Akron common stock from a financial point of view. Following discussion and the presentation of Piper Sandler, the Akron board of directors, with the exception of one director, determined that the merger with CNB, in accordance with the terms and conditions of the merger agreement, was fair to, and in the best interests of, Akron and its shareholders, after which the directors adopted resolutions to approve the merger and the merger agreement and authorized management to execute and deliver the merger agreement, as well as take all other actions appropriate to perform Akron’s obligations under the merger agreement. Subject to the exercise of the Akron board of directors’ fiduciary duties and pursuant to the terms of the merger agreement, the Akron board of directors also resolved to recommend that the shareholders of Akron approve the merger and the merger agreement.

On December 18, 2019, the CNB board of directors held a special meeting, with representative of Griffin and Hogan Lovells present. During this meeting, the CNB board of directors reviewed and considered the proposed merger with Akron and the terms of the merger agreement. After discussion, the CNB board of directors approved the transaction and authorized CNB’s management to execute and deliver the merger agreement.

Following the meetings of the Akron board of directors and the CNB board of directors on December 18, 2019, the parties executed the merger agreement and related documents, and publicly announced the transaction in a press release.

Akron’s Reasons for the Merger

In reaching its decision to approve the merger agreement and related transactions, the Akron board of directors consulted with executive management, the board’s financial advisors, and its legal counsel and considered a number of factors, including, among others, the following, which are not presented in order of priority:

• a combined Akron and CNB may create a company with sufficient size and scale to more efficiently compete in a highly-competitive industry;

• the likelihood of a need for additional capital, and CNB’s access to capital to support future growth and address likely future regulatory requirements for the industry generally;

• the combined company’s potential to increase shareholder value and to create opportunities for enhanced earnings and potential dividends;

• increased liquidity for Akron’s shareholders resulting from the merger, and the fact that CNB’s common shares are traded on the NASDAQ Global Stock Market;

• projected increased dividend payout levels;

• the current and prospective business and economic environment in which Akron operates, including local and regional economic conditions;

• the continuing consolidation in the financial services industry;

• increased regulatory burdens on financial institutions;

• the uncertainties in the regulatory and economic climate going forward;

37

• the compatibility of Akron’s and CNB’s respective core philosophies and the similarities between the markets served by Akron and CNB;

• the business, earnings, operations, financial condition, management, prospects, capital levels and asset quality of Akron;

• the financial analysis prepared by Piper Sandler and the opinion of Piper Sandler to the effect that, as of the date thereof and subject to the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler as set forth therein, the merger consideration was fair, from a financial point of view, to the holders of Akron common stock;

• the form and amount of merger consideration, and the ability of Akron’s shareholders to participate in the future performance of the combined company;

• the belief by the Akron board of directors that CNB is a high-quality financial services company with a compatible business culture and shared approach to customer service and increasing shareholder value;

• the belief of the Akron board of directors that CNB shares Akron’s commitment to supporting Akron’s local communities and developing the local economies;

• CNB’s plan to retain many of Akron’s front-line employees, enabling Akron customers to continue to interact with the same people after the merger;

• the increased lending opportunities in the communities served by Akron as a result of the combined banks’ increased lending limits;

• economies of scale with respect to overhead and operating expenses of the combined company;

• the effect of the merger on Akron’s employees, including the prospects for continued employment and the other benefits agreed to be provided by CNB to Akron’s employees; and

• the effect of the merger on Akron’s customers and the communities in which they conduct business.

The Akron board of directors also considered a variety of potentially negative factors in its deliberations concerning the merger agreement and the merger, including the following, which are not presented in order of priority:

• Akron would lose the autonomy associated with being an independent financial institution;

• Akron’s customers may be hesitant to engage with a much larger financial institution;

• the fact that, while Akron expects that the merger will be consummated, there can be no assurance that all conditions to the parties’ obligations to complete the merger agreement will be satisfied, including the risks that necessary regulatory or shareholder approvals might not be obtained and, as a result, the merger may not be consummated;

• the risk that any potential benefits and synergies sought in the merger may not be realized or may not be realized within the expected time period, and the risks associated with the integration of the two companies;

• the restrictions of the conduct of Akron’s business prior to the completion of the merger, which are customary for merger agreements such as the merger agreement between Akron and CNB, but which, subject to specific exceptions, could delay or prevent Akron from undertaking business opportunities that may arise or any other action it would otherwise take with respect to the operations of Akron absent the pending completion of the merger;

• the significant risks and costs involved in connection with entering into and completing the merger, of failing to complete the merger in a timely manner, or at all, including as a result of any failure to obtain required regulatory approvals, such as the risks and costs relating to diversion of management and employee attention, potential employee attrition, and the potential effect on business and customer relationships;

38

• the fact that Akron would be prohibited from affirmatively soliciting acquisition proposals after execution of the merger agreement, and the possibility that the $2.5 million termination fee payable by Akron upon the termination of the merger agreement under certain circumstances could discourage other potential acquirers from making a competing bid to acquire Akron;

• the possibility of litigation in connection with the merger;

• the other risks described under the heading “Risk Factors” beginning on page 18; and

• as Akron currently does not anticipate asking Piper Sandler to update its opinion, that the opinion will not address the fairness of the merger consideration, from a financial point of view, at the time the merger is completed.

During its consideration of the merger agreement, Akron’s board of directors was also aware that Akron officers and directors may have financial interests in the merger that are different from, or are in addition to, the interests of Akron shareholders and took those issues into consideration in negotiating the merger agreement. See “—Interests of Akron’s Directors and Executive Officers in the Merger,” beginning on page 52.

The foregoing discussion of the factors considered by the Akron board of directors is not intended to be exhaustive, but does set forth the principal factors considered by the board. Based on the factors described above, the Akron board of directors determined that the merger with CNB Bank would be advisable and in the best interests of Akron shareholders and approved the merger agreement and related transactions contemplated by the merger agreement and recommended approval of the proposed merger by Akron shareholders. In view of the wide variety and complexity of factors considered by the Akron board of directors in connection with its evaluation of the merger, the board of directors did not consider it practical, and did not attempt, to quantify, rank or otherwise assign relative weights to the specific factors it considered in reaching its decision and did not undertake to make any specific determination as to whether any particular factor, or any aspect of any factor, was favorable or unfavorable to the ultimate determination of the board. Rather, the Akron board of directors made its recommendation based on the totality of information presented to and the investigation conducted by it. In considering the factors discussed above, individual directors may have given different weights to different individual factors.

Recommendation of the Akron Board of Directors

The Akron board of directors has approved the merger agreement and recommends that Akron’s shareholders vote“FOR”approval of the merger agreement.

Opinion of Akron’s Financial Advisor

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

Piper Sandler acted as financial advisor to Akron’s board of directors in connection with the proposed transaction and participated in certain of the negotiations leading to the execution of the merger agreement. At the December 18, 2019 meeting at which Akron’s board of directors considered the merger and the merger agreement, Piper Sandler delivered to the board of directors its oral opinion, which was subsequently confirmed in writing on December 18, 2019, to the effect that, as of such date, the merger consideration was fair to the holders of Akron common stock from a financial point of view.The full text of Piper Sandler’s opinion is attached as Annex C to this proxy statement/prospectus. The opinion outlines the procedures followed,

39

assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler 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 Akron common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

Piper Sandler’s opinion was directed to the board of directors of Akron in connection with its consideration of the merger and the merger agreement and does not constitute a recommendation to any shareholder of Akron as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the merger and the merger agreement. Piper Sandler’s opinion was directed only to the fairness, from a financial point of view, of the merger consideration to the holders of Akron common stock and did not address the underlying business decision of Akron 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 Akron or the effect of any other transaction in which Akron might engage. Piper Sandler also 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 Akron or CNB, or any class of such persons, if any, relative to the compensation to be received in the merger by any other shareholder. Piper Sandler’s opinion was approved by Piper Sandler’s fairness opinion committee.

In connection with its opinion, Piper Sandler reviewed and considered, among other things:

• a draft of the merger agreement, dated December 18, 2019;

• certain publicly available financial statements and other historical financial information of Akron that Piper Sandler deemed relevant;

• certain publicly available financial statements and other historical financial information of CNB that Piper Sandler deemed relevant;

• certain internal financial projections for Akron for the year ending December 31, 2019 as well as estimated long-term annual earnings per share and net income growth rates for the years ending December 31, 2020 through December 31, 2023 and estimated dividends per share for the years ending December 31, 2019 through December 31, 2023, as provided by the senior management of Akron;

• publicly available median analyst earnings per share and dividends per share estimates for CNB for the years ending December 31, 2019 and December 31, 2020, as adjusted by the senior management of CNB and its representatives to provide for a capital raising transaction expected to be completed by CNB in the first quarter of 2020, as well as an estimated long-term annual earnings per share growth rate for the years ending December 31, 2021 through December 31, 2023 and estimated dividends per share for the years ending December 31, 2021 through December 31, 2023, as provided by the senior management of CNB and its representatives;

• the pro forma financial impact of the merger on CNB based on certain assumptions relating to purchase accounting adjustments, transaction expenses and cost savings, as well as an estimated earnings per share growth rate for Akron for the years ending December 31, 2020 through December 31, 2023, as provided by the senior management of CNB;

• the publicly reported historical price and trading activity for Akron common stock and CNB common stock, including a comparison of certain stock market information for Akron common stock and CNB 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 Akron and CNB with similar financial institutions for which information is publicly available;

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

40

• 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 Piper Sandler considered relevant.

Piper Sandler also discussed with certain members of the senior management of Akron the business, financial condition, results of operations and prospects of Akron and held similar discussions with certain members of the management of CNB and its representatives regarding the business, financial condition, results of operations and prospects of CNB.

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

In preparing its analyses, Piper Sandler used certain internal financial projections for Akron for the year ending December 31, 2019 as well as estimated long-term annual earnings per share and net income growth rates for the years ending December 31, 2020 through December 31, 2023 and estimated dividends per share for the years ending December 31, 2019 through December 31, 2023, as provided by the senior management of Akron. In addition, Piper Sandler used publicly available median analyst earnings per share and dividends per share estimates for CNB for the years ending December 31, 2019 and December 31, 2020, as adjusted by the senior management of CNB and its representatives to provide for a capital raising transaction expected to be completed by CNB in the first quarter of 2020, as well as an estimated long-term annual earnings per share growth rate for the years ending December 31, 2021 through December 31, 2023 and estimated dividends per share for the years ending December 31, 2021 through December 31, 2023, as provided by the senior management of CNB and its representatives. Piper Sandler also received and used in its pro forma analyses certain assumptions relating to purchase accounting adjustments, transaction expenses and cost savings, as well as an estimated earnings per share growth rate for Akron for the years ending December 31, 2020 through December 31, 2023, as provided by the senior management of CNB. With respect to the foregoing information, the respective senior managements of Akron and CNB confirmed to Piper Sandler that such information reflected (or, in the case of the publicly available median analyst estimates referred to above, were consistent with) the best currently available projections, estimates and judgments of those respective managements as to the future financial performance of Akron and CNB, respectively, and the other matters covered thereby. Piper Sandler expressed no opinion as to such information, or the assumptions on which such information was based. Piper Sandler also assumed that there had been no material change in the respective assets, financial condition, results of operations, business or prospects of Akron or CNB since the date of the most recent financial statements made available to Piper Sandler. Piper Sandler assumed in all respects material to its analyses that Akron and CNB would remain as going concerns for all periods relevant to its analyses.

41

Piper Sandler also assumed, with Akron’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 transaction, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on Akron, CNB, the merger or any related transactions, and (iii) the merger and any related transactions 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. Finally, with Akron’s consent, Piper Sandler relied upon the advice that Akron 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. Piper Sandler expressed no opinion as to any such matters.

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

In rendering its opinion, Piper Sandler performed a variety of financial analyses. The summary below is not a complete description of all the analyses underlying Piper Sandler’s opinion or the presentation made by Piper Sandler to Akron’s board of directors, but is a summary of the material analyses performed and presented by Piper Sandler. 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. Piper Sandler 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 Piper Sandler’s comparative analyses described below is identical to Akron or CNB 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 transaction values, as the case may be, of Akron and CNB and the companies to which they were compared. In arriving at its opinion, Piper Sandler did not attribute any particular weight to any analysis or factor that it considered. Rather, Piper Sandler made qualitative judgments as to the significance and relevance of each analysis and factor. Piper Sandler 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, Piper Sandler made its determination as to the fairness of the merger consideration to the holders of Akron common stock 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, Piper Sandler also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which cannot be predicted and are beyond the control of Akron, CNB, and Piper Sandler. The analyses performed by Piper Sandler 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. Piper Sandler prepared its analyses solely for purposes of rendering its opinion and

42

provided such analyses to Akron’s board of directors at its December 18, 2019 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, Piper Sandler’s analyses do not necessarily reflect the value of Akron common stock or CNB common stock or the prices at which Akron common stock or CNB common stock may be sold at any time. The analyses of Piper Sandler and its opinion were among a number of factors taken into consideration by Akron’s board of directors in making its determination to approve the merger agreement and the analyses described below should not be viewed as determinative of the decision of Akron’s board of directors with respect to the fairness of the merger consideration.

Summary of Proposed Transaction Consideration and Implied Transaction Metrics.

Piper Sandler reviewed the financial terms of the proposed merger. Pursuant to the terms of the merger agreement, at the effective time of the merger, each share of Akron common stock issued and outstanding immediately prior to the effective time of the merger, except for certain shares as set forth in the merger agreement, shall be converted into the right to receive the following, without interest: (i) for each share of Akron common stock with respect to which a cash election has been effectively made and not revoked or lost pursuant to the merger agreement, the right to receive cash from CNB in an amount equal to $215.00 (the “Cash Consideration”); or (ii) for each share of Akron common stock with respect to which a stock election has been effectively made and not revoked or lost pursuant to the merger agreement, the right to receive 6.6729 shares of CNB common stock (the “Stock Consideration”). The merger agreement provides, generally, that seventy-five percent (75%) of the total number of shares of Akron common stock shall be converted into the Stock Consideration and twenty-five percent (25%) of such shares of Akron common stock shall be converted into the Cash Consideration in accordance with the election, allocation and proration procedures set forth in the merger agreement. Piper Sandler calculated an aggregate implied transaction value of approximately $65.8 million and an implied purchase price per share of $219.28 consisting of the implied value of 300,000 shares of Akron common stock based on the closing price of CNB common stock on December 17, 2019. Based upon financial information for Bank of Akron as of or for the last twelve months (“LTM”) ended September 30, 2019 and the closing price of CNB common stock on December 17, 2019, Piper Sandler calculated the following implied transaction metrics:

Transaction Price / Akron September 30, 2019 Book Value per Share:	171	%
Transaction Price / Akron September 30, 2019 Tangible Book Value per Share:	171	%
Transaction Price / Akron LTM Earnings per Share:	13.9	x
Transaction Price / Akron LTM Core Earnings per Share(1):	17.3	x
Transaction Price / Akron 2019E Core Earnings per Share(2):	17.7	x
Tangible Book Premium / Core Deposits(3):	9.6	%
Tangible Book Premium / Core Deposits(4):	8.4	%
Market Premium as of December 17, 2019:	23.9	%

1 Core LTM earnings per share (“EPS”) as defined by S&P Global Market Intelligence; Excludes $1.162 million of realized gain on securities

2 2019 Estimated EPS based on $3.7 million Core Net Income, as provided by Akron management

3 Core deposits defined as total deposits less time deposits with balances greater than $100,000

4 Core deposits defined as total deposits less time deposits with balances greater than $250,000

Net Present Value Analyses.

Piper Sandler performed an analysis that estimated the net present value of Akron common stock assuming Akron performed in accordance with certain internal financial projections for Akron for the year ending December 31, 2019 as well as estimated long-term annual earnings per share and net income growth rates for the years ending December 31, 2020 through December 31, 2023 and estimated dividends per share for the years ending December 31, 2019 through December 31, 2023, as provided by the senior management of Akron. To approximate the terminal value of a share of Akron common stock at December 31, 2023, Piper Sandler applied price to 2023 earnings multiples ranging from 10.0x to 20.0x and multiples of December 31, 2023 tangible book value ranging from 100% to 150%. The terminal values were then discounted to present values using different discount rates ranging from 11.0% to 15.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Akron common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of Akron common stock of $101.55 to $225.70 when applying multiples of earnings and $107.94 to $182.71 when applying multiples of tangible book value.

Piper Sandler also considered and discussed with Akron’s board of directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to earnings. To illustrate this impact, Piper Sandler performed a similar analysis, assuming Akron’s earnings varied from 20.0% above projections to 20.0% below projections. This analysis resulted in the following range of per share values for Akron’s common stock, applying the price to 2023 earnings multiples range of 10.0x to 20.0x referred to above and a discount rate of 12.99%.

Piper Sandler also performed an analysis that estimated the net present value per share of CNB common stock, assuming CNB performed in accordance with publicly available median analyst earnings per share and dividends per share estimates for CNB for the years ending December 31, 2019 and December 31, 2020, as adjusted by the senior management of CNB and its representatives to provide for a capital raising transaction expected to be completed by CNB in the first quarter of 2020, as well as an estimated long-term annual earnings per share growth rate for the years ending December 31, 2021 through December 31, 2023 and estimated dividends per share for the years ending December 31, 2021 through December 31, 2023, as provided by the senior management of CNB and its representatives. To approximate the terminal value of a share of CNB common stock at December 31, 2023, Piper Sandler applied price to 2023 earnings multiples ranging from 10.0x to 17.5x and multiples of December 31, 2023 tangible book value ranging from 145% to 220%. The terminal values were then discounted to present values using different discount rates ranging from 10.0% to 14.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of CNB common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of CNB common stock of $20.34 to $39.54 when applying multiples of earnings and $24.71 to $42.29 when applying multiples of tangible book value.

Piper Sandler 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.

Pro Forma Transaction Analysis.

Piper Sandler analyzed certain potential pro forma effects of the merger on CNB assuming the transaction closes on June 30, 2020. Piper Sandler also utilized the following information and assumptions: (a) certain internal financial projections for Akron for the year ending December 31, 2019 as well as estimated long-term annual earnings per share and net income growth rates for the years ending December 31, 2020 through December 31, 2023 and estimated dividends per share for the years ending December 31, 2019 through December 31, 2023, as provided by the senior management of Akron, (b) publicly available median analyst earnings per share and dividends per share estimates for CNB for the years ending December 31, 2019 and December 31, 2020, as adjusted by the senior management of CNB and its representatives to provide for a capital raising transaction expected to be completed by CNB in the first quarter of 2020, as well as an estimated long-term annual earnings per share growth rate for the years ending December 31, 2021 through December 31, 2023 and estimated dividends per share for the years ending December 31, 2021 through December 31, 2023, as provided by the senior management of CNB and its representatives, and (c) certain assumptions relating to purchase accounting adjustments, transaction expenses and cost savings, as well as an estimated earnings per share growth rate for Akron for the years ending December 31, 2020 through December 31, 2023, as provided by the senior management of CNB. The analysis indicated that the transaction could be accretive to CNB’s estimated earnings per share (excludingone-time transaction costs and expenses) in the years ending December 31, 2020 through December 31, 2023 and dilutive to CNB’s estimated tangible book value per share at close and at December 31, 2020, December 31, 2021, December 31, 2022 and December 31, 2023.

In connection with this analysis, Piper Sandler considered and discussed with Akron’s 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 merger, and noted that the actual results achieved by the combined company may vary from projected results and the variations may be material.

Piper Sandler’s Relationship.

Piper Sandler is acting as Akron’s financial advisor in connection with the transaction and will receive a fee for such services in an amount equal to 1.575%, which fee is contingent upon the closing of the merger. At the time of announcement of the merger, Piper Sandler’s fee was approximately $1.0 million. Piper Sandler also received a $150,000 fee from Akron upon rendering its opinion, which opinion fee will be credited in full towards the advisory fee which will become payable to Piper Sandler upon closing of the merger. Akron has also agreed to indemnify Piper Sandler against certain claims and liabilities arising out of Piper Sandler’s engagement and to reimburse Piper Sandler for certain of itsout-of-pocket expenses incurred in connection with Piper Sandler’s engagement.

In the two years preceding the date of Piper Sandler’s opinion, Piper Sandler did not provide any other investment banking services to Akron. Piper Sandler did not provide any investment banking services to CNB in

the two years preceding the date of Piper Sandler’s opinion. In the ordinary course of Piper Sandler’s business as a broker-dealer, Piper Sandler may purchase securities from and sell securities to Akron, CNB and their respective affiliates. Piper Sandler may also actively trade the equity and debt securities of Akron, CNB and their respective affiliates for Piper Sandler’s account and for the accounts of Piper Sandler’s customers.

Certain Akron Unaudited Prospective Financial Information

Akron does not as a matter of course make public long-term projections as to future revenues, earnings or other results due to, among other reasons, the uncertainty of the underlying assumptions and estimates. However, in connection with the merger, Akron’s management prepared and provided to the Akron board of directors in connection with its evaluation of the transaction, and to its financial advisor Piper Sandler, including in connection with Piper Sandler’s financial analyses described above under the section entitled “ —Opinion of Akron’s Financial Advisor,” certain unaudited prospective financial information regarding Akron’s operations for fiscal years 2019 through 2023 (the “Akron Projections”). The below summary of the Akron Projections is included for the purpose of providing Akron shareholders access to certain nonpublic information that was furnished to certain parties in connection with the merger, and such information may not be appropriate for other purposes, and is not included to influence the voting decision of any Akron shareholder.

Akron’s unaudited prospective financial information was not prepared with a view toward public disclosure, nor was it prepared with a view toward compliance with published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. The inclusion of this unaudited prospective financial information should not be regarded as an indication that such information is predictive of actual future events or results and such information should not be relied upon as such, and readers of this joint proxy statement/prospectus are cautioned not to place undue reliance on the unaudited prospective financial information. The unaudited prospective financial information included in this joint proxy statement/prospectus has been prepared by, and is the responsibility of, Akron management.

While presented with numeric specificity, this unaudited prospective financial information was based on numerous variables and assumptions (including assumptions related to industry performance and general business, economic, market and financial conditions and additional matters specific to Akron’s business) that are inherently subjective and uncertain and are beyond the control of Akron’s management. Important factors that may affect actual results and cause this unaudited prospective financial information not to be achieved include, but are not limited to, risks and uncertainties relating to Akron’s business (including their ability to achieve strategic goals, objectives and targets over applicable periods), industry performance, general business and economic conditions and other factors described in the sections entitled “Information Regarding Forward-Looking Statements” and “Risk Factors.” This unaudited prospective financial information also reflects numerous variables, expectations and assumptions available at the time they were prepared as to certain business decisions that are subject to change. As a result, actual results may differ materially from those contained in this unaudited prospective financial information. Accordingly, there can be no assurance that the projected results summarized below will be realized.

None of Akron, CNB or their respective officers, trustees, directors, affiliates, advisors or other representatives can give you any assurance that actual results will not differ materially from this unaudited prospective financial information.

AKRON UNDERTAKES NO OBLIGATION TO UPDATE OR OTHERWISE REVISE OR RECONCILE THIS UNAUDITED PROSPECTIVE FINANCIAL INFORMATION TO REFLECT CIRCUMSTANCES EXISTING AFTER THE DATE THIS UNAUDITED PROSPECTIVE FINANCIAL INFORMATION WAS GENERATED OR TO REFLECT THE OCCURRENCE OF FUTURE EVENTS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING SUCH INFORMATION ARE SHOWN TO BE IN ERROR. SINCE THE UNAUDITED PROSPECTIVE FINANCIAL INFORMATION COVERS MULTIPLE YEARS, SUCH INFORMATION BY ITS NATURE BECOMES LESS PREDICTIVE WITH EACH SUCCESSIVE YEAR.

Akron has not made and makes no representation to CNB or any CNB shareholder, in the merger agreement or otherwise, concerning this unaudited prospective financial information or regarding Akron’s ultimate performance compared to the unaudited prospective financial information or that the projected results will be achieved. In light of the foregoing factors and the uncertainties inherent in the unaudited prospective financial information, Akron urges all Akron shareholders not to place undue reliance on such information.

The following table presents selected unaudited prospective financial data for the fiscal years ending 2019 through 2023 for Akron on a standalone basis. The Akron Projections were prepared by Akron’s management solely for internal purposes. The Akron Projections were not updated to account for any circumstances or events occurring after the date they were initially prepared and therefore should not be relied on as predictive of actual future results.

Employment Agreement with Anthony Delmonte

Anthony J. Delmonte, Jr. is party to an employment agreement with Akron that includes benefits payable in the event of a termination of employment following a change of control of Akron. If Mr. Delmonte is terminated without “cause” or he terminates employment for “good reason” (each as defined in the employment agreement) within six (6) months before and on account of a change in control, or such termination occurs within two (2) years following a change in control, Mr. Delmonte will be entitled to receive, in addition to any accrued compensation, continued payment of his base salary for a period of twenty four (24) months following his date of termination, which as of January 27, 2020, would equal payments totaling an aggregate amount of approximately $438,780.

Change of Control Severance Agreement with Joseph Ondesko

Joseph M. Ondesko is party to a change of control severance agreement with Akron which for benefits payable in the event of a termination of employment following a change of control of Akron. If Mr. Ondesko is terminated without cause or terminated upon change of control by either (a) an involuntary termination within twelve (12) months of a change of control or (b) if within twelve (12) months of a change of control Mr. Ondesko resigns based on a “constructive termination” (as defined in the change of control severance agreement) and that resignation occurs within ninety (90) days following such constructive termination, Mr. Ondesko will be entitled to receive, in addition to any accrued compensation and benefits, continued payment of his base salary forfifty-two (52) weeks following his termination date, which as of January 27, 2020, would equal payments totaling an aggregate amount of approximately $169,950.

Advisory Board Appointment for an Akron Existing Director or Officer

Immediately following the effective time of the merger, CNB has agreed that it will expand the Advisory Board of CNB Bank by one (1) seat and designate one officer or director of Akron (selected by CNB in consultation with Akron) to serve on the Advisory Board. This Advisory Board member will be paid a fee for each Advisory Board meeting attended in an amount consistent with the amount paid by CNB Bank to members of its currently existing Advisory Board. This per meeting amount is currently $450.00, paid in shares of CNB common stock.

Indemnification

Pursuant to the merger agreement, all rights to indemnification and all limitations of liability existing in favor of any director or officer of Akron as provided for in Akron’s organization certificate orby-laws with respect to matters occurring on or prior to the effective time of the merger will continue in full force and effect to the extent provided by applicable law.

Officers’ and Directors’ Insurance

Akron and CNB agreed that prior to the effective time of the merger, Akron will purchase extended reporting period endorsement under Akron’s existing directors’ and officers’ liability insurance coverage for Akron’s

53

directors and officers, for a period of six years following the effective time of the merger. If the cost of that liability insurance is over 150% of the amount currently being paid by Akron for such insurance, then Akron will enter into an agreement to spend up to that amount to purchase lesser coverage as may be obtained with such amount.

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

The following summary describes the anticipated material U.S. federal income tax consequences of the merger to U.S. holders (as defined below) of Akron’s common stock. The following summary is based upon the Internal Revenue Code of 1986, or the Code, its legislative history, existing and proposed regulations thereunder and published rulings and decisions, all as currently in effect as of the date hereof, and all of which are subject to change, possibly with retroactive effect. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax consequences set forth below. Tax considerations under state, local and foreign laws, under federal laws other than those pertaining to income tax, and under federal laws applicable to alternative minimum taxes are not addressed in this proxy statement/prospectus.

For purposes of this summary, we use the term “U.S. holder” to mean a beneficial owner which is:

• an individual citizen or resident of the United States;

• a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States or any of its political subdivisions;

• a trust that (1) is subject to the supervision of a court within the United States and the control of one or more U.S. persons or (2) has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a U.S. person; or

• an estate that is subject to U.S. federal income taxation on its income regardless of its source.

If a partnership or other entity taxed as a partnership holds Akron common stock, the tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership. Partnerships and partners in such partnerships should consult their tax advisors about the tax consequences of the merger to them.

This summary addresses only those U.S. holders of Akron common stock that hold their Akron common stock as a capital asset within the meaning of Section 1221 of the Code and does not address all the U.S. federal income tax consequences that may be relevant to particular holders of Akron common stock in light of their individual circumstances or to holders of Akron common stock that are subject to special rules, such as:

• financial institutions;

• pass-through entities and investors in pass-through entities;

• insurance companies;

• tax-exempt organizations;

• dealers in securities or currencies;

• traders in securities that elect to use a mark to market method of accounting;

• persons that hold Akron common stock as a hedge or as part of a straddle, constructive sale or conversion transaction, or other risk management transaction;

• regulated investment companies;

• real estate investment trusts;

• expatriates or persons whose “functional currency” is not the U.S. dollar;

54

• persons who are not U.S. holders;

• retirement plans; and

• holders who acquired their shares of Akron common stock through the exercise of an employee stock option or otherwise as compensation.

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

Tax Consequences of the Merger Generally. The merger is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. If, as intended, the merger qualifies as a reorganization, the material U.S. federal income tax consequences will be as follows:

• no gain or loss will be recognized by CNB or Akron as a result of the merger;

• no gain or loss will be recognized by U.S. holders who exchange all of their Akron common stock solely for CNB common stock pursuant to the merger (with respect to cash received instead of a fractional share of CNB common stock, see below under “Receipt of Cash Consideration Only and Cash Received Instead of a Fractional Share of CNB Common Stock”);

• gain (but not loss) will be recognized by U.S. holders of Akron common stock who receive both shares of CNB common stock and cash in exchange for shares of Akron common stock pursuant to the merger, in an amount equal to the lesser of (1) the amount by which the sum of the fair market value of the CNB common stock and cash received by a U.S. holder of Akron common stock exceeds such U.S. holder’s basis in its Akron common stock and (2) the amount of cash received by such U.S. holder of Akron common stock (except with respect to U.S. holders who receive cash only or cash instead of a fractional share of CNB common stock, which is discussed below under “Receipt of Cash Consideration Only and Cash Received Instead of a Fractional Share of CNB Common Stock”);

• the aggregate basis of the CNB common stock received by a U.S. holder of Akron common stock in the merger (including the basis of fractional shares of CNB common stock deemed received, prior to their deemed redemption as described below) will be the same as the aggregate basis of Akron common stock for which it is exchanged, decreased by the amount of cash (if any) received in the merger (other than cash received instead of fractional share interests in CNB common stock), and increased by the amount of gain recognized on the exchange (other than gain recognized with respect to cash received instead of fractional share interests in CNB common stock, as discussed below under “Receipt of Cash Consideration Only and Cash Received Instead of a Fractional Share of CNB Common Stock”); and

• the holding period of CNB common stock received in exchange for shares of Akron common stock (including fractional shares of CNB common stock deemed received and redeemed as described below) will include the holding period of Akron common stock for which it is exchanged.

If a U.S. holder of Akron common stock acquired different blocks of Akron common stock at different times or at different prices, any gain or loss will be determined separately with respect to each block of Akron common stock, and the cash and shares of CNB common stock received will be allocated pro rata to each such block of stock. In computing the amount of gain realized, if any, a U.S. holder of Akron common stock may not offset a loss realized on one block of shares against the gain realized on another block of shares. U.S. holders should consult their tax advisors with regard to identifying the bases and holding periods of the particular shares of CNB common stock received in the merger.

At the time that a U.S. holder makes a cash or stock election pursuant to the terms of the merger agreement, such U.S. holder will not know whether, and to what extent, the proration provisions of the merger agreement might

55

alter the mix of consideration such U.S. holder will receive. As a result, the U.S. federal income tax consequences to such U.S. holder will not be ascertainable with certainty until such U.S. holder knows the precise amount of cash and/or CNB common shares that such U.S. holder will receive in the merger.

Completion of the merger is conditioned on, among other things, the receipt by CNB and Akron of legal opinions from Hogan Lovells US LLP and Hodgson Russ LLP, respectively, each dated as of the closing date of the merger, that for U.S. federal income tax purposes the merger will be treated as a “reorganization” within the meaning of Section 368(a) of the Code. In addition, prior to the effectiveness of the registration statement of which this proxy statement/prospectus is a part, each of Hogan Lovells US LLP and Hodgson Russ LLP will deliver an opinion to CNB and Akron, respectively, to the same effect as the opinions described above. These opinions will be based on certain assumptions and on representations and covenants contained in representation letters provided by Akron and CNB and will assume that these representations are true, correct and complete, and that Akron and CNB, as the case may be, will comply with these covenants. Although the merger agreement allows each of CNB and Akron to waive its tax opinion closing condition, neither CNB nor Akron currently anticipates waiving this condition. If either CNB or Akron does waive its tax opinion closing condition after the registration statement of which this proxy statement/prospectus is a part is declared effective by the Securities and Exchange Commission, and if the U.S. federal income tax consequences of the merger to Akron shareholders have materially changed, CNB and Akron will recirculate the proxy statement/prospectus and resolicit the shareholder vote of Akron. Neither of the legal opinions will be binding on the Internal Revenue Service or on any court. Neither CNB nor Akron intends to request any ruling from the Internal Revenue Service as to the U.S. federal income tax consequences of the merger and there is no guarantee that the Internal Revenue Service will treat the merger as a “reorganization” within the meaning of Section 368(a) of the Code.

Taxation of Capital Gain.Except as described under “Additional Considerations—Recharacterization of Gain as a Dividend” below, gain that U.S. holders of Akron common stock recognize in connection with the merger generally will constitute capital gain and will constitute long-term capital gain if such U.S. holders have held (or are treated as having held) their Akron common stock for more than one year as of the date of the merger. For U.S. holders of Akron common stock that arenon-corporate holders, long-term capital gain is generally taxed at preferential rates. You are urged to consult with your own tax advisors about the U.S. federal income tax rate on long-term capital gain applicable to you.

Additional Considerations—Recharacterization of Gain as a Dividend.In limited circumstances, all or part of the gain that a particular U.S. holder of Akron common stock recognizes could be treated as dividend income rather than capital gain. Because the possibility of dividend treatment depends primarily upon the particular circumstances of a holder of Akron common stock, including the application of certain constructive ownership rules, U.S. holders of Akron common stock should consult their own tax advisor regarding the potential tax consequences of the merger to them.

Receipt of Cash Consideration Only and Cash Received Instead of a Fractional Share of CNB Common Stock.A U.S. holder of Akron common stock who receives the entirety of its consideration in the form of cash will generally recognize gain or loss equal to the difference between the amount of cash received and its tax basis in its Akron common stock. In addition, a U.S. holder of Akron common stock who receives cash instead of a fractional share of CNB common stock will be treated as having received the fractional share pursuant to the merger and then as having exchanged the fractional share for cash in a redemption by CNB. As a result, such U.S. holder of Akron common stock will generally recognize gain or loss equal to the difference between the amount of cash received and its tax basis in its fractional share interest as set forth above. The gain or loss recognized by the U.S. holders described in this paragraph will generally be capital gain or loss, and will be long-term capital gain or loss if, as of the effective date of the merger, the U.S. holder’s holding period for the relevant shares is greater than one year. The deductibility of capital losses is subject to limitations.

You are urged to consult with your own tax advisors about the particular tax consequences of the merger to you, including the effects of U.S. federal, state and local, foreign and other tax laws.

56

Backup Withholding and Information Reporting.Payments of cash to a U.S. holder of Akron common stock pursuant to the merger are subject to information reporting and may, under certain circumstances, be subject to backup withholding unless the U.S. holder provides CNB with its taxpayer identification number and otherwise complies with the backup withholding rules. Any amounts withheld from payments to a U.S. holder under the backup withholding rules are not additional tax and generally will be allowed as a refund or credit against the U.S. holder’s federal income tax liability, provided that the U.S. holder timely furnishes the required information to the Internal Revenue Service.

A U.S. holder of Akron common stock who receives CNB common stock as a result of the merger will be required to retain records pertaining to the merger. Each U.S. holder of Akron common stock who is required to file a U.S. federal income tax return and who is a “significant holder” that receives CNB common stock in the merger will be required to file a statement with such U.S. federal income tax return setting forth such holder’s basis in Akron common stock surrendered and the fair market value of the CNB common stock and cash received in the merger. A “significant holder” is a holder of Akron common stock, who, immediately before the merger, owned at least 5% of the outstanding stock of Akron or has a tax basis of $1 million or more in its Akron common stock.

This summary does not address tax consequences that may vary with, or are contingent on, individual circumstances. Moreover, it does not address anynon-income tax or any foreign, state or local tax consequences of the merger. Tax matters are very complicated, and the tax consequences of the merger to you will depend upon the facts of your particular situation. Accordingly, we strongly urge you to consult with a tax advisor to determine the particular federal, state, local and foreign income and other tax consequences to you of the merger.

Regulatory Approvals Required for the Merger

General. CNB and Akron have agreed to use their reasonable best efforts to obtain all permits, consents, approvals and authorizations of all third parties and governmental authorities that are necessary to consummate the merger. This includes the approval of the FDIC and the PADOBS. CNB Bank will file the application materials necessary to obtain these regulatory approvals. The merger cannot be completed without such approvals. CNB and Akron cannot assure you that all required regulatory approvals will be obtained, when they will be received or whether there will be conditions in the approvals or any litigation challenging the approvals.

FDIC. The Bank Merger Act requires the prior written approval of the FDIC before any insured depository institution may merge or consolidate with another insured depository institution if the resulting institution is to be a statenon-member bank. As a statenon-member bank, CNB’s subsidiary, CNB Bank, expects to file its application for approval of the merger with the FDIC in February, 2020.

The Bank Merger Act prohibits the FDIC from approving any proposed merger transaction that would result in a monopoly, or would further a combination or conspiracy to monopolize or to attempt to monopolize the business of banking in any part of the United States. Similarly, the Bank Merger Act prohibits the FDIC from approving a proposed merger transaction whose effect in any section of the country may be substantially to lessen competition, or to tend to create a monopoly, or which in any other manner would be in restraint of trade.

In every proposed merger transaction, the FDIC must also consider the financial and managerial resources and future prospects of the existing and proposed institutions, the convenience and needs of the community to be served, and the effectiveness of each insured depository institution involved in the proposed merger transaction in combatting money-laundering activities, including in overseas branches. In addition, the FDIC must consider the effectiveness of the companies in combating money laundering activities. Further, the FDIC must consider the extent to which the proposed transaction would result in greater or more concentrated risks to the stability of the United States banking or financial system. Any transaction approved by the FDIC may not be completed until 30 days after such approval. With the concurrence of the U.S. Department of Justice, the waiting period may be reduced to 15 days.

57

Pennsylvania Department of Banking and Securities. Pursuant to Chapter 16 of the Pennsylvania Banking Code of 1965, as amended, a merger that will result in a Pennsylvania state-chartered institution must be approved by the PADOBS. In every proposed merger transaction the PADOBS must consider, among other things, whether the proposed transaction adequately protects the interests of depositors, other creditors and shareholders. The PADOBS also must consider whether the proposed transaction would be consistent with adequate and sound banking and in the public interest on the basis of the financial history and condition of the parties, their prospects, the character of their management, the potential effect of the merger or consolidation on competition and the convenience and needs of the area primarily to be served by the resulting institution.

Accounting Treatment of the Merger

The merger will be accounted for using the purchase method of accounting with CNB treated as the acquiror. Under this method of accounting, Akron’s assets and liabilities will be recorded by CNB at their respective fair values as of the closing date of the merger and added to those of CNB. Any excess of purchase price over the net fair values of Akron’s assets and liabilities will be recorded as goodwill. The excess of the fair value of Akron’s net assets over the purchase price, if any, will be recognized in earnings by CNB on the closing date of the merger. Financial statements of CNB issued after the merger will reflect these values, but will not be restated retroactively to reflect the historical financial position or results of operations of Akron prior to the merger. The results of operations of Akron will be included in the results of operations of CNB beginning on the effective date of the merger.

Dissenters’ Appraisal Rights

Dissenters’ rights are statutory rights that enable shareholders to dissent from an extraordinary transaction, such as a merger, and to demand that the company pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to shareholders in connection with the merger.

If the merger agreement is approved, a holder of Akron common stock who does not vote in favor of the merger agreement may be entitled to seek relief as a dissenting shareholder under Section 6022 of the NYBL.

The following is intended as a brief summary of the material provisions of the New York statutory procedures that an Akron shareholder must follow in order to dissent from the merger and obtain payment of the fair value of their shares of Akron common stock instead of the merger consideration. This summary is qualified by reference to Section 6022 and other provisions of the NYBL. Any shareholder contemplating exercise of dissenting shareholders’ rights is urged to review carefully the provisions of Section 6022 and to consult an attorney, since failure to follow fully and precisely the procedural requirements of the NYBL may result in termination or waiver of those rights. A copy of Section 6022 of the NYBL is attached to this proxy statement/prospectus asAnnex B and is incorporated herein by reference.

To perfect dissenting shareholders’ rights, a dissenting Akron shareholder must satisfy each of the following conditions and must otherwise comply with Section 6022 of the NYBL:

• Must be a shareholder of record. A dissenting shareholder must be a record holder of shares of Akron common stock on                     , 2020, the record date established for determining those shareholders entitled to vote on the proposal to approve the merger agreement. Because only shareholders of record on the record date may exercise dissenting shareholders’ rights, any person who beneficially owns shares that are held of record by a broker, bank or other nominee and who desires to exercise dissenting shareholders’ rights must, in all cases, instruct the broker, bank or other nominee holding the shares to satisfy all of the requirements outlined under Section 6022 of the NYBL.

• Must file a notice of objection to the action and notice of the election to dissent. Prior to the shareholder vote upon the approval of the merger agreement, any shareholder seeking to perfect dissenting shareholders’ rights must give written notice of their objection to the action and their

58

intention to demand payment for their shares if the action is taken. Such objection is not required from any shareholder who did not receive notice of the meeting to approve the proposed action or where the proposed action is authorized by written consent of the shareholders without a meeting.

If the action to which the shareholder objects is approved, within ten (10) days after the vote authorizing the action takes place, or written consent is obtained from the requisite shareholders, the corporation shall give written notice of such authorization or consent to each shareholder who filed written objection, excepting any shareholders who voted for or consented in writing to the proposed action. Within twenty (20) days of receiving such notice any shareholder who properly filed notice of their objection and elects to dissent to the action shall file with the corporation written notice of such election. This notice must specify the shareholder’s name and address, the number and class of shares held by the shareholder on the record date, and a demand for payment of the fair value of their shares. Shareholders of record should send their demand for payment to:

Bank of Akron

P.O. Box 358

Akron, NY 14001

Attention: Jessica Brandi

• Deliver certificates for placement of a legend. Within one (1) month of filing the notice of election to dissent, the dissenting shareholder must deliver their share certificates to the corporation or their transfer agent for endorsement thereon that an election to dissent has been made. At the option of the corporation, a dissenting shareholder who fails to deliver their certificates may have their dissenting shareholder’s rights terminated, unless a court, for good cause shown, otherwise directs.

The corporation and the dissenting shareholders may come to an agreement as to the fair value of the dissenting shareholders’ shares. The corporation must make an offer for the fair value of such shares within seven days after the expiration of the period within which shareholders may file their notices of election to dissent, or within seven days after the proposed corporate action is consummated, whichever is later. If the corporation fails to make such offer within such period of seven days or if the corporation and any of the dissenting shareholders cannot agree upon the fair value of the shares within thirty (30) days of the corporation’s offer, then either the corporation (or, in the case of merger, the receiving corporation) may, within twenty (20) days after the expiration of whichever is applicable of the two last periods mentioned, file a petition in the Supreme Court in Erie County, New York to determine the rights of the dissenting shareholders and to fix the fair value of their shares. If the corporation (or, in the case of merger, the receiving corporation) fails to institute such a proceeding within the twenty (20) day period, then the dissenting shareholders may institute such proceeding for the same purpose within thirty (30) days of the expiration of such twenty day period. The cost of the proceeding, including reasonable compensation to the appraisers to be determined by the court, will be assessed against the corporation, except that all or any part of such costs may be apportioned and assessed against the dissenting shareholders if the court finds their refusal to accept the offer was arbitrary, vexatious or otherwise not in good faith.

Restrictions on Sales of Shares by Certain Affiliates

The shares of CNB common stock to be issued in the merger will be freely transferable under the Securities Act, except for shares issued to any shareholder who is an “affiliate” of CNB as defined by Rule 144 under the Securities Act. Affiliates consist of individuals or entities that control, are controlled by, or are under common control with CNB and include the executive officers and directors of CNB and may include significant shareholders of CNB.

Stock Exchange Listing

Following the merger, the shares of CNB common stock will continue to trade on the NASDAQ Global Select Market under the symbol “CCNE.”

THE MERGER AGREEMENT

This section of the document describes the material terms of the merger agreement. The following summary is qualified in its entirety by reference to the complete text of the merger agreement, which is incorporated in this proxy statement/prospectus by reference and attached asAnnex A to this proxy statement/prospectus. This summary may not contain all of the information about the merger agreement that may be important to you. You are urged to read the full text of the merger agreement. The merger agreement contains customary representations and warranties of CNB and Akron made to each other as of specific dates. The assertions embodied in those representations and warranties were made solely for purposes of the contract between CNB and Akron and are not intended to provide factual, business, or financial information about CNB or Akron. Moreover, some of those representations and warranties may not be accurate or complete as of any specified date, may be subject to a contractual standard of materiality different from those generally applicable to shareholders or different from what a shareholder might view as material, may have been used for purposes of allocating risk between CNB and Akron rather than establishing matters as facts, may have been qualified by certain disclosures not reflected in the merger agreement that were made to the other party in connection with the negotiation of the merger agreement and generally were solely for the benefit of the parties to that agreement.

Structure of the Merger

Subject to the terms and conditions of the merger agreement, and in accordance with the Pennsylvania Banking Code of 1965, as amended, and the New York Banking Law, as amended, at the completion of the merger, Akron will merge with and into CNB Bank, a wholly-owned subsidiary of CNB. CNB Bank will be the surviving bank in the merger and will continue its corporate existence under the laws of the Commonwealth of Pennsylvania. Upon completion of the merger, the separate corporate existence of Akron will terminate.

Each share of CNB common stock that is issued and outstanding at the effective time of the merger will remain issued and outstanding as one share of common stock of CNB, and each share of Akron common stock issued and outstanding at the effective time of the merger (excluding dissenters’ shares) will be converted into the right to elect to receive either (x) $215.00 in cash, without interest, or (y) 6.6729 shares of CNB common stock, subject to proration procedures that may modify the shareholder’s election to ensure that no more than 25% of the outstanding shares of Akron common stock (including any dissenters’ shares but excluding shares of Akron common stock to be canceled in connection with the merger) are exchanged for cash, as described below. See “—Consideration to be Received in the Merger.”

The amended and restated articles of incorporation of CNB Bank will be the articles of incorporation of the combined company, and theby-laws of CNB Bank will be the bylaws of the combined company. The articles of incorporation andby-laws of CNB will not change in connection with the proposed transaction. See “Comparison of Shareholder Rights” beginning on page 79.

The merger agreement provides that CNB may, prior to the approval of the merger agreement by the shareholders of Akron, change the method of effecting the business combination between CNB and Akron. However, no such change may (A) alter or change the amount of merger consideration to be issued to Akron shareholders under the merger agreement, (B) adversely affect the tax treatment of Akron’s shareholders under the merger agreement, (C) adversely affect the tax treatment of CNB or Akron under the merger agreement, or (D) materially impede or delay consummation of the transactions contemplated by the merger agreement.

Effective Time and Timing of Closing

The merger will be completed and become effective when CNB Bank and Akron execute and file certificates of merger with the PADOBS. The closing of the merger will take place (A) on a date specified by both parties, which shall be no later than five business days after the conditions to the closing of the merger (other than

60

conditions to be satisfied at the closing) have been satisfied or waived, or (B) on such other date as CNB and Akron may agree. CNB and Akron anticipate that the merger will be completed in the third quarter of 2020. However, completion of the merger could be delayed if there is a delay in obtaining the required regulatory approvals or in satisfying any other conditions to the merger. There can be no assurances as to whether, or when, CNB and Akron will obtain the required approvals or complete the merger.

CNB’s and CNB Bank’s Board of Directors After the Merger

The directors of CNB and CNB Bank will not change in connection with the proposed transaction.

Immediately following the effective time of the merger, CNB has agreed that it will expand the Advisory Board of CNB Bank by one (1) seat and designate one officer or director of Akron (selected by CNB in consultation with Akron) to serve on the Advisory Board.

Consideration to be Received in the Merger

The merger agreement provides that Akron shareholders will have the right, with respect to each of their shares of Akron common stock, to elect to receive, subject to certain proration and other provisions as described below, either (i) $215.00 in cash, without interest, or (ii) 6.6729 shares of CNB common stock. At least 75% of the number of shares of Akron common stock outstanding as of the effective time of the merger (including any dissenters’ shares but excluding shares of Akron common stock to be canceled in accordance with the terms of the merger agreement) will be converted into shares of CNB common stock.

No guarantee can be made that you will receive solely cash, if you so elect. As a result of the proration provisions and other limitations described in this document and in the merger agreement, you may receive CNB common stock or cash in amounts that vary from the amounts you elect to receive. The proportion of stock and cash to be issued in the merger is also subject to potential adjustment for tax purposes.

Non-Electing Akron Shareholders. Akron shareholders who make no election to receive cash or CNB common stock in the merger, and Akron shareholders who do not make a valid election, will be deemed not to have made an election. Shareholders not making an election will be paid in CNB common stock.

Proration. The maximum number of shares of Akron common stock to be converted into cash consideration in the merger will be 25% of the outstanding shares of Akron common stock (including any shares for which dissenters’ rights are appropriately exercised but excluding shares of Akron common stock to be canceled in accordance with terms of the merger agreement). The remaining shares of Akron common stock will be converted into shares of CNB common stock. Therefore, elections are subject to certain proration and other provisions to preserve this requirement regarding the maximum number of shares of Akron common stock to be converted into cash in the merger.

If the Akron shareholders’ election and the number of shares of Akron common stock for which dissenters’ rights are appropriately exercised would result in more than 25% of the outstanding shares of Akron common stock (including any shares for which dissenters’ rights are appropriately exercised but excluding shares of Akron common stock to be canceled in accordance with terms of the merger agreement) being exchanged for cash, then all Akron shareholders who elected to receive stock consideration or who did not make an election will receive stock consideration, and all shareholders who have elected to receive cash consideration will receive the following:

• a number of shares of CNB common stock (rounded to the nearest whole share) equal to the product obtained by multiplying (i) the number of shares for which such shareholder made elections to receive the cash consideration and (ii) a fraction, the numerator of which is the amount by which (a) the sum of the number of shares for which all Akron shareholders made elections to receive cash consideration

61

and the number of shares of Akron common stock for which dissenters’ rights are appropriately exercised exceeds (b) the maximum number of shares of Akron common stock to be converted into cash consideration, and the denominator of which is the number of shares for which elections were made to receive the cash consideration, and

• the right to receive cash consideration for the remaining number of such shareholder’s shares.

If the Akron shareholders’ elections and the number of shares of Akron common stock for which dissenters’ rights are appropriately exercised would result in 25% or fewer of the outstanding shares of Akron common stock (including any shares for which dissenters’ rights are appropriately exercised but excluding shares of Akron common stock to be canceled in accordance with the terms of the merger agreement) being exchanged for cash, then all Akron shareholders who elected to receive cash consideration will receive cash consideration and all Akron shareholders who elected to receive stock consideration or made no election will receive stock consideration.

Fractions of Shares. No fractional shares of CNB common stock will be issued to any holder of Akron common stock upon completion of the merger. For each fractional share that would otherwise be issued, CNB will pay each shareholder cash (without interest) in an amount equal to the product obtained by multiplying (A) the fractional share interest to which the holder would otherwise be entitled by (B) the average of the daily closing sales prices of CNB common stock reported on the NASDAQ Global Select Market for the ten consecutive trading days immediately preceding but not including the trading day prior to the closing date for the merger.

Conversion. The conversion of Akron’s common stock into the merger consideration will occur automatically upon completion of the merger. Under the merger agreement, after the effective time, CNB will cause its exchange agent to pay the “purchase price” to each Akron shareholder who surrenders the appropriate documents to the exchange agent. The term “purchase price” refers to the (i) shares of CNB’s common stock, (ii) cash (if any) and (iii) any cash to be paid instead of a fraction of a share of CNB common stock, payable to each holder of Akron’s common stock.

Election Procedures for Shareholders; Surrender of Stock Certificates

If you own Akron common stock, you will soon receive under separate cover an election form. The election form entitles the record holder of Akron common stock to specify (a) the number of shares of Akron common stock owned by such holder for which the holder elects to receive stock consideration, or (b) the number of shares of Akron common stock owned by such holder for which the holder elects to receive cash consideration. If no election is made, then such holder shall receive stock consideration in the merger as outlined above.

To make an effective election, a shareholder of record must submit a properly completed election form to American Stock Transfer & Trust Company, LLC, which will be acting as the exchange agent, on or before 5:00 p.m., New York City time, on                 , 2020, or the election deadline, which is the day prior to the Akron special meeting of shareholders. You may change or revoke your election at any time prior to the election deadline by written notice received by the exchange agent prior to the election deadline accompanied by a properly completed and signed, revised election form. You may revoke your election by written notice received by the exchange agent prior to the election deadline. All elections will be revoked automatically if the merger agreement is terminated.

You may not revoke or change your elections following the election deadline.

If you do not submit a properly completed election form or revoke your election form prior to the election deadline, your shares of Akron common stock will be designated asnon-election shares and you will receive stock consideration as outlined above. Prior to the effective time of the merger, CNB will deposit with the exchange agent certificates representing CNB’s common stock sufficient to pay the aggregate stock

62

consideration and sufficient cash to permit payment of the aggregate cash consideration and cash in lieu of fractional shares of CNB common stock. No later than five business days following the effective time of the merger, the exchange agent will mail to each holder of record of Akron share certificates which immediately prior to the effective time of the merger represented outstanding shares of Akron common stock which were converted into the right to receive merger consideration and any cash in lieu of fractional shares of CNB common stock a letter of transmittal, together with instructions for use in surrendering the shareholder’s Akron stock certificates in exchange for the merger consideration and any cash in lieu of fractional shares. Upon surrendering his or her certificate(s) representing shares of Akron’s common stock, together with the signed letter of transmittal, the Akron shareholder shall be entitled to receive, as applicable (i) certificate(s) representing a number of whole shares of CNB’s common stock determined in accordance with the exchange ratio, (ii) a check representing the amount of cash to which such holder shall have become entitled to, and (iii) a check representing the amount of cash in lieu of fractional shares. You will not be paid dividends or other distributions declared after the merger with respect to any CNB common stock into which your shares of Akron common stock have been converted until you surrender your Akron stock certificates for exchange. No interest will be paid or accrue to Akron shareholders on the cash consideration, cash instead of fractional shares or unpaid dividends and distributions, if any. After the effective time, there will be no further transfers of the Akron common stock. Akron stock certificates presented for transfer after the completion of the merger will be cancelled and exchanged for the merger consideration.

If your stock certificates have been lost, stolen or destroyed, you will have to prove your ownership of these certificates and certify that they were lost, stolen or destroyed before you receive any consideration for your shares.

If any portion of the merger consideration is to be paid to persons other than the person in whose name the certificate for shares of Akron common stock is registered, it is a condition of payment that the Akron common stock certificate be properly endorsed or otherwise be in proper form for transfer and that the person requesting the payment either:

• inform the exchange agent whether any transfer or other taxes are required by reason of the payment to a person other than the registered holder of the certificate surrendered, or

• establish to the reasonable satisfaction of the exchange agent that the tax has been paid or is not payable.

Any portion of the merger consideration made available to the exchange agent that remains unclaimed by Akron shareholders six months after the effective time of the merger may be returned to CNB. Akron shareholders who have not exchanged their shares of Akron common stock for the merger consideration in accordance with the merger agreement before that time may look only to CNB for payment of the merger consideration for these shares, cash in lieu of fractional shares and any unpaid dividends or distributions with respect to CNB common stock payable upon due surrender of the Akron common stock certificates. In any event, CNB and the exchange agent will not be liable to any Akron shareholder for any amount properly delivered to a public official under applicable abandoned property, escheat or similar laws.

Akron Shareholders’ Meeting

Akron has agreed to call, hold and convene a special meeting of its shareholders to consider and vote upon the approval of the merger agreement. Akron has also agreed to ensure that its shareholders’ meeting is called, noticed, convened, held and conducted in compliance with state law, its organization certificate andby-laws and all other applicable legal requirements.

Additionally, the board of directors of Akron has agreed to recommend that Akron shareholders vote to approve the merger agreement and any other matters required to be approved by Akron shareholders for consummation of the merger.

No Solicitation of Alternative Transactions

Akron has agreed that neither it nor its subsidiaries nor any of its respective officers, directors, employees, investment bankers, financial advisors, attorneys, accountants, consultants, affiliates and other of its agents (which we refer to as Akron’s representatives) will, directly or indirectly:

• 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;

• subject to certain exceptions, participate in any discussions or negotiations regarding any acquisition proposal or furnish, or otherwise afford access, to any person (other than CNB) any information or data with respect to Akron or any of its subsidiaries or otherwise relating to an acquisition proposal;

• release any person from, waive any provisions of, or fail to enforce any confidentiality agreement or standstill agreement to which Akron is a party; or

• subject to certain exceptions, 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.

Under the merger agreement, an “acquisition proposal” means any inquiry, offer or proposal (other than an inquiry, offer or proposal from CNB), 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 Akron 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 Akron or any of its subsidiaries representing, in the aggregate, 15% or more of the assets of Akron 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 15% or more of the votes attached to the outstanding securities of Akron or any of its subsidiaries;

• any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning 15% or more of any class of equity securities of Akron or any of its subsidiaries; or

68

• any transaction which is similar in form, substance or purpose to any of the transactions listed above, or any combination of these types of transactions.

If Akron receives a bona fide unsolicited written acquisition proposal that did not result from a breach by Akron of any of thenon-solicitation provisions in the merger agreement as discussed above, the Akron board of directors may (i) participate in discussions or negotiations regarding the unsolicited acquisition proposal or furnish the third party with, or otherwise afford the third party access to any information or data with respect to Akron or any of its subsidiaries or otherwise relating to the acquisition proposal, and (ii) subject to certain exceptions, 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, if:

• the Akron board of directors first determines in good faith, (1) after consultation with its outside legal counsel and a nationally recognized, independent financial advisor, that such acquisition proposal constitutes or is reasonably likely to lead to a superior proposal, and (2) after consultation with its outside legal counsel, that it is required to take such actions to comply with its fiduciary duties to its shareholders under applicable law;

• Akron has provided CNB with at least two business days’ prior notice that the Akron board of directors is reasonably likely to make such a determination; and

• prior to furnishing or affording access to any information or data with respect to Akron or any of its subsidiaries or otherwise relating to an acquisition proposal, the third party enters into a confidentiality agreement with Akron containing terms no less favorable to Akron than those contained in its confidentiality agreement with CNB.

A “superior proposal” means 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 Akron board of directors determines in its good faith judgment, after consultation with outside legal counsel and an independent financial advisor of nationally recognized reputation:

• would, if consummated, result in the acquisition of all, but not less than all, of the issued and outstanding shares of Akron’s common stock or all, or substantially all, of the assets of Akron and its subsidiaries on a consolidated basis;

• would result in a transaction that:

• involves consideration to the Akron shareholders that is more favorable, from a financial point of view, than the consideration to be paid to Akron shareholders pursuant to the merger agreement, considering, among other things, the nature of the consideration being offered and any material regulatory approvals or other risks, financing conditions or other contingencies associated with the consummation or timing of the proposed transaction beyond or in addition to those specifically contemplated by the merger agreement; and

• is, in light of the other terms of such proposal, more favorable to Akron shareholders than the merger and the transactions contemplated by the merger agreement; and

• 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.

Akron has agreed to promptly, and in any event within 24 hours, notify CNB 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, Akron or any of its representatives, in each case in connection with any acquisition proposal. Any such notice will include the name of the person initiating such discussions or negotiations or making such proposal, offer or information request, 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, copies

69

of these materials, except to the extent that such materials constitute confidential information of the party making such offer or proposal under an effective confidentiality agreement. Akron is also required to keep CNB informed, on a reasonably 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).

Akron has also agreed to provide CNB with anynon-public information about Akron or any of its subsidiaries provided to any other person that was not previously provided to CNB, no later than the date provided to such other person.

In addition, under the merger agreement, Akron agreed that its board of directors, or any committee of the board, will not:

• withdraw, qualify, amend or modify, or propose to withdraw, qualify, amend or modify, in a manner adverse to CNB in connection with the transactions contemplated by the merger agreement (including the merger), its recommendation that Akron shareholders vote to approve the merger agreement;

• fail to reaffirm its recommendation that Akron shareholders vote to approve the merger agreement within five business days following a request by CNB;

• make any statement, filing or release, in connection with the special meeting or otherwise, inconsistent with its recommendation that Akron shareholders vote to approve the merger agreement (including taking a neutral position or no position with respect to an acquisition proposal);

• approve or recommend, or propose to approve or recommend, any acquisition proposal; or

• enter into any letter of intent, agreement in principle, acquisition agreement or other agreement related to any acquisition transaction (other than a confidentiality agreement entered into in accordance with thenon-solicitation provisions of the merger agreement); or requiring Akron to abandon, terminate or fail to consummate the merger or any other transaction contemplated by the merger agreement.

However, prior to the date of the special meeting of Akron shareholders, the Akron board of directors may withdraw, qualify, amend or modify its recommendation that Akron shareholders vote to approve the merger agreement if the Akron board reasonably determines in good faith, after consultation with outside legal counsel and a nationally recognized financial advisor, that (A) an unsolicited acquisition proposal that Akron received (that did not result from a breach of thenon-solicitation provisions of the merger agreement) constitutes a superior proposal and (B) it is required to do so in order to comply with its fiduciary duties to the Akron shareholders under applicable law. In the event that the Akron board makes this determination, Akron must provide three business days’ prior written notice to CNB that its board has decided that the bona fide unsolicited written acquisition proposal constitutes a superior proposal. During the three business days after CNB’s receipt of the notice of a superior proposal, Akron and its board must cooperate and negotiate in good faith with CNB to make any adjustments, modifications or amendments to the terms and conditions of the merger agreement as would enable Akron to proceed with its board’s original recommendation with respect to the merger agreement without requiring Akron to withdraw, qualify, amend or modify its board’s recommendation with respect to the merger agreement. At the end of the three business day period, and after taking into account any such adjusted, modified or amended terms as may have been proposed by CNB during that period, the Akron board must again determine in good faith, after consultation with outside legal counsel, that:

• it is required to withdraw, qualify, amend or modify its recommendation with respect to the merger agreement to comply with its fiduciary duties to its shareholders under applicable law; and

• the acquisition proposal is a superior proposal.

In the event of any material revisions to the superior proposal, Akron must provide a new notice of such superior proposal to CNB. During the one business day period following receipt of such new written notice, Akron and its board must cooperate and negotiate in good faith with CNB to make any adjustments, modifications or

70

amendments to the terms and conditions of the merger agreement as would enable Akron to proceed with its board’s original recommendation with respect to the merger agreement without requiring Akron to withdraw, qualify, amend or modify its board’s recommendation with respect to the merger agreement.

Employee Benefits

Under the terms of the merger agreement, as soon as practicable after the effective time of the merger, CNB will provide the employees of Akron and any of its subsidiaries who remain employed after the effective time of the merger with at least the types and levels of employee benefits comparable in the aggregate to those maintained for similarly-situated employees of CNB. CNB has the right in its sole discretion to terminate, merge or continue any of Akron’s employee benefit plans, except that CNB will maintain Akron’s plans (other than stock-based plans, incentive plans or defined benefit plans) until the employees of Akron and any of its subsidiaries are permitted to participate in comparable CNB plans. To the extent that Akron’s employees become eligible to participate in CNB’s employee benefit plans after the merger, CNB will:

• provide each employee with eligibility and vesting credit, but not benefit accrual credit with respect to CNB’s plans and not for participation in or accrual under any retiree health plan or executive supplemental retirement plan, equal to the amount of service credited by Akron prior to the merger, unless such credit would result in a duplication of benefits;

• subject to the terms of CNB’s employee plans, not treat any employee of Akron or any of its subsidiaries as a “new” employee for purposes of any exclusions under any health or similar plan of CNB for anypre-existing medical condition, except to the extent such employee was treated as a “new” employee under the Akron health plan; and

• subject to the terms of CNB’s employee plans, provide for any deductibles,co-payments orout-of-pocket expenses paid under Akron’s health plans to be credited toward deductibles,co-payments orout-of-pocket expenses under CNB’s health plans upon delivery to CNB of appropriate documentation.

In addition, CNB has agreed to cause Akron and its subsidiaries to honor and continue to be obligated to perform all contractual rights of current and former employees and directors of Akron or any of its subsidiaries existing as of the date of the merger agreement under the terms of certain employment, severance, deferred compensation, change in control and supplemental retirement plans of Akron and its subsidiaries. CNB has also agreed to pay to each employee of Akron or any of its subsidiaries who is not covered by a written employment or severance agreement and either (i) not offered continued employment by CNB or CNB Bank after the effective time, or (ii) is terminated by CNB or any of its subsidiaries, without cause, within 12 months following the effective time, a severance payment equal to two weeks of his or her then current base salary multiplied by the number of total completed years of service with Akron or any Akron subsidiary. The minimum severance payment will equal four weeks of the employee’s base salary and the maximum severance payment shall not exceed 26 weeks of his or her base salary. Immediately prior to the effective time, Akron will accrue all unused sick time with respect to its employees and pay such amounts to its employees, subject to applicable withholding, as of the effective time.

If requested by CNB at least 15 days before the effective time of the merger, Akron has agreed to terminate its 401(k) plan as of the day prior to the effective time (but contingent upon the occurrence of the effective time). If, as a result of the merger, either CNB, Akron or any of their affiliates is required before or as of the effective time of the merger to provide notice of any employment loss to any employees of Akron or any of its subsidiaries or any person under the federal Worker Adjustment and Retraining Notification Act of 1988 or any state or local laws, regulations or ordinances related to plant closing, relocations, mass layoffs or employment losses, Akron has agreed to give all such required notices within the time frames required by applicable law, regulation or ordinance. From and after the effective time of the merger, to the extent not previously paid by Akron, CNB has agreed to cause CNB Bank and its subsidiaries to pay certain bonuses that are payable in 2020 or on or around the effective time of the merger, as described above in the section entitled “The Merger Agreement – Conduct of Business Pending the Merger – Conduct of Business of Akron Pending the Merger.”

Under the merger agreement, CNB has agreed that all rights to indemnification and all limitations of liability existing in favor of any director or officer of Akron or any of its subsidiaries, as provided in the organization certificate andby-laws of Akron, similar governing documents of an Akron subsidiary or in applicable law as in effect on the date of the merger agreement with respect to matters occurring on or prior to the effective time of the merger will survive the merger.

Directors’ and Officers’ Insurance. The merger agreement provides for Akron to purchase an extended reporting period endorsement under its existing directors’ and officers’ liability insurance coverage prior to the effective time of the merger in a form acceptable to Akron. This extended reporting period endorsement will provide Akron’s directors and officers with coverage for six years following the effective time of the merger of not less than the existing coverage under, and have other terms at least as favorable to the insured persons as, the directors’ and officers’ liability insurance coverage presently maintained by Akron so long as the aggregate cost is less than 150% of the annual premium currently paid by Akron for such insurance. In the event that this premium limit is insufficient for such coverage, Akron will enter into an agreement to spend up to that amount to purchase such lesser coverage as may be obtained with such amount.

The Voting Agreements

Each of the directors of Akron has entered into a voting agreement with CNB. In the voting agreements, each director has each agreed to vote, and granted CNB an irrevocable proxy and power of attorney to vote, all of his or her shares of Akron common stock:

• against another acquisition proposal, or any agreement or transaction that is intended, or could reasonably be expected, to materially impede, interfere or be inconsistent with, delay, postpone, discourage or materially and adversely affect the consummation of the transactions contemplated by the merger agreement or of the voting agreement or the performance by the shareholder of his obligations under the voting agreement.

Under each such voting agreement, each Akron director has agreed not to, and not to permit any of his or her affiliates, to:

Preemptive Rights	Preemptive rights generally allow shareholders to maintain their proportionate share of ownership of a corporation by permitting the shareholders to purchase a proportionate share of any new stock issuances. Preemptive rights protect the shareholders from dilution of value and control upon new stock issuances.
	Akron’s organization certificate, does not grant shareholders any preemptive rights.	Under CNB’s articles of incorporation, the shares of stock of CNB shall not have preemptive rights.
	Neither Akron shareholders nor CNB shareholders have preemptive rights.
Dividends	The NYBL provides that dividends may be paid in cash, property or shares of a corporation’s capital stock. The NYBL further provides that a corporation may pay dividends out of surplus except when there is any impairment of capital stock, or when the declaration, payment, or distribution would be contrary to any restrictions contained in the organization certificate.	Under the BCL, the board of directors may declare and pay dividends, unless after paying such distribution the corporation would be unable to pay its debts as they come due, the total assets of the corporation would be less than the sum of its total liabilities plus the amount that would be needed, if the corporation were to be dissolved at the time as of which the distribution is measured, to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the distributions.
	Akron and CNB may each declare and pay dividends.

	Akron	CNB
Business Combinations	The NYBL provides that in the case of stock corporations a merger is authorized by the affirmative vote, at a duly organized meeting, of the stockholders owning at leasttwo-thirds (2/3) of the stock of each corporation in the merger.	Subject to certain exceptions, the BCL provides that the affirmative action of a majority of the outstanding shares entitled to vote shall be required in order to effect the merger or consolidation of a corporation. CNB’sby-laws provide that whenever any corporate action is to be taken by vote of its shareholders, such action shall be authorized upon receiving the affirmative vote of a majority of the votes cast by all shareholders entitled to vote thereon and, if any shareholders are entitled to vote thereon as a class, upon receiving the affirmative vote of a majority of the votes cast by the shareholders entitled to vote as a class. CNB’s articles of incorporation provide that in order to effect the merger or consolidation of CNB into another corporation which is not a wholly-owned subsidiary of CNB, the affirmative vote ofsixty-six percent (66%) of the outstanding shares entitled to vote is required.
	CNB requires shareholders’ majority approval for the merger. By statute Akron requires atwo-thirds affirmative vote.

Pennsylvania Anti-Takeover Provisions

Under the BCL certain anti-takeover provisions apply to Pennsylvania publicly traded companies including those relating to (i) control share acquisitions, (ii) disgorgement of profits by certain controlling persons, (iii) business combination transactions with interested shareholders and (iv) the rights of shareholders to demand fair value for their stock following a control transaction. Pennsylvania law allows registered corporations toopt-out of any of these anti-takeover provisions. CNB has not opted out of the anti-takeover provisions listed above. A general summary of the applicable anti-takeover provisions is set forth below.

Control Share Acquisitions. The BCL limits control share acquisitions relating to the act of acquiring for the first time voting power over voting shares equal to at least 20%, 33 1/3% and 50% of the voting power of the corporation. Once a control share acquisition has occurred, then all shares in excess of the number required to meet the applicable threshold, plus shares purchased at any time with the intention of making a control share acquisition and shares purchased within 180 days of the date the triggering threshold was exceeded, are considered control shares. Control shares cannot vote either until their voting rights have been restored by two separate votes of the shareholders, as described below, at a meeting or until they have been transferred to a person who does not thereby also become the holder of control shares.

The holder of control shares may wait until the next annual or special meeting after the acquisition took place to submit the request for the restoration of voting rights to the shareholders, or the acquiring person may accelerate the process by agreeing to underwrite the cost of a special meeting of shareholders for that purpose. In either

86

case, the acquiring person is required to furnish for distribution to the shareholders an information statement containing a detailed disclosure concerning the acquiring person, its intentions with respect to ownership of securities of the corporation and other matters. The restoration of voting rights may only be approved by the affirmative vote of the holders of a majority of the voting power entitled to vote in two separate votes of all of (i) the disinterested shareholders and (ii) the voting shares of the corporation.

For a period of 24 months after the later of (i) a control share acquisition by an acquiring person who does not properly request consideration of voting rights, or (ii) the denial of such a request or lapse of voting rights, the corporation may redeem all the control shares at the average public market sales price of the shares on the date notice of the call for redemption is given by the corporation.

Disgorgement of Profits by Certain Controlling Persons. Under the BCL, disgorgement of profits by certain controlling persons applies in the event that (i) any person or group publicly discloses that the person or group may acquire control of the corporation, or (ii) a person or group acquires (or publicly discloses an intent to acquire) 20% or more of the voting power of the corporation and, in either case, sells shares within 18 months thereafter. Any profits from sales of equity securities of the corporation received by the person or group during such18-month period will belong to the corporation if the securities that were sold were acquired during the18-month period or within 24 months prior thereto.

Business Combination Transactions with Interested Shareholders. The BCL prohibits certain business combinations with “interested shareholders,” defined as persons who acquire the direct or indirect beneficial ownership of shares entitled to cast at least 20% of the votes entitled to be cast for the election of directors. A corporation subject to this provision may not effect mergers or certain other business combinations with the interested shareholder for a period of five years, unless:

• the business combination or the acquisition of stock by means of which the interested shareholder became an interested shareholder is approved by the corporation’s board of directors prior to such stock acquisition;

• the business combination is approved by the affirmative vote of the holders of all the outstanding common shares of the corporation; or

• the business combination is approved by the affirmative vote of the holders of a majority of all shares entitled to vote, excluding shares held by the interested shareholders, and at the time of such vote, the interested shareholder is the beneficial owner of at least 80% of the voting shares of the corporation. This exception applies only if the value of the consideration to be paid by the interested shareholder in connection with the business combination satisfies certain fair price requirements.

After the five-year restricted period, an interested shareholder of the corporation may engage in a business combination with the corporation if (i) the business combination is approved by the affirmative vote of a majority of the shares other than those beneficially owned by the interested shareholder and its affiliates, or (ii) the merger is approved at a shareholders meeting and certain fair price requirements are met.

Rights of Shareholders to Demand Fair Value for Stock Following a Control Transaction. The BCL provides, generally, that following a control transaction, any holder of voting shares may, prior to or within a reasonable time following the giving of notice by the controlling person, demand that the controlling person pay them the fair value of their shares under specified procedures. Fair value may not be less than the highest price paid per share by the controlling person at any time during the90-day period ending on and including the date on which the controlling person became such, plus any increment representing any value, such as a control premium, that is not reflected in such price.

87

LEGAL MATTERS

The validity of the shares of CNB common stock to be issued in the merger will be passed upon for CNB by Hogan Lovells US LLP, 555 Thirteenth Street, NW, Columbia Square, Washington, D.C. 20004.

For purposes of this Agreement: (x) “Exchange Ratio” means 6.6729 shares of CNB Common Stock; and (y) the Cash Consideration and Stock Consideration are sometimes referred to herein collectively as the “Merger Consideration.”

(b)        Notwithstanding anything herein to the contrary, no Dissenters’ Shares shall be converted into the Merger Consideration pursuant to thisSection 2.01, but instead shall be treated in accordance with the provisions set forth inSection 2.05.

(c)        At the Effective Time, all shares of Company Common Stock that are owned by the Company as treasury stock and all shares of Company Common Stock that are owned directly or indirectly by CNB or the Company, including any shares of Company Common Stock held by CNB or the Company or any of their respective Subsidiaries in respect of a debt previously contracted, other than shares that are held by CNB or the Company, if any, in a fiduciary capacity, shall be canceled and shall cease to exist and no cash or other consideration shall be delivered in exchange therefor. All shares of CNB Common Stock that are owned by the Company shall become treasury stock of CNB.

(d)        At least 75% of the aggregate Merger Consideration plus the aggregate consideration to be paid by CNB with respect to the Dissenters’ Shares (the “Total Consideration”) to be paid to holders of Company Common Stock will be paid with CNB Common Stock. In the event that the foregoing clauses of thisSection 2.01 result in less than 75% of the aggregate Total Consideration being paid with CNB Common Stock, pro rata adjustments will be made in accordance withSection 2.02 to result in payment of 75% of the aggregate Total Consideration in CNB Common Stock and the balance of the aggregate Total Consideration in cash.

A-3

(e)        If either of the tax opinions referred to inSection 7.02(c) orSection 7.03(c)cannot be rendered (as reasonably determined, in each case, by the counsel charged with giving such opinion) as a result of the Merger potentially failing to satisfy the “continuity of interest” requirements under applicable federal income tax principles relating to reorganizations under Section 368(a) of the Code, then CNB shall reduce the Cash Consideration and increase the Stock Consideration to the minimum extent necessary to enable the relevant tax opinions to be rendered.

Section 2.02    Proration.

(a)        Notwithstanding any other provision contained in this Agreement, the maximum number of shares of Company Common Stock to be converted into Cash Consideration (the “Maximum Cash Conversion Number”) shall be equal to the product obtained by multiplying (x) the number of shares of Company Common Stock issued and outstanding as of the Effective Time (including any Dissenters’ Shares but excluding shares of Company Common Stock to be canceled as provided inSection 2.01(c)) by (y) 0.25.

(b)        Within five (5) Business Days after the Effective Time, CNB shall cause the Exchange Agent (as defined below) to effect the allocation among holders of Company Common Stock of rights to receive the Cash Consideration and the Stock Consideration as follows:

(i)        If the sum of the Cash Election Shares plus any Dissenters’ Shares is greater than the Maximum Cash Conversion Number, then

(A)      all Stock Election Shares andNon-Election Shares shall be converted into the right to receive the Stock Consideration; and

(B)      the Cash Election Shares of each holder thereof shall be converted into the right to receive the Stock Consideration in respect of that number of Cash Election Shares (rounded to the nearest whole share) equal to the product obtained by multiplying (x) the number of Cash Election Shares held by such holder by (y) a fraction, the numerator of which is the amount by which (1) the sum of the Cash Election Shares plus any Dissenters’ Shares exceeds (2) the Maximum Cash Conversion Number and the denominator of which is the total number of Cash Election Shares, with the remaining number of such holder’s Cash Election Shares being converted into the right to receive the Cash Consideration.

(ii)        If the sum of the Cash Election Shares plus any Dissenters’ Shares is equal to or less than the Maximum Cash Conversion Number, then all Cash Election Shares shall be converted into the right to receive the Cash Consideration and all Stock Election Shares andNon-Election Shares shall be converted into the right to receive the Stock Consideration.

Section 2.03    Election and Exchange Procedures. Each holder of record (“Holder”) of shares of Company Common Stock (other than Dissenters’ Shares) shall have the right, subject to the limitations set forth in this Article II, to submit an election in accordance with the following procedures:

(a)        Each Holder may specify in a request made in accordance with the provisions of thisSection 2.03 (herein called an “Election”) (x) the number of shares of Company Common Stock owned by such Holder with respect to which such Holder desires to make a Stock Election and (y) the number of shares of Company Common Stock owned by such Holder with respect to which such Holder desires to make a Cash Election.

(b)        CNB shall prepare a form reasonably acceptable to the Company (the “Form of Election”) which shall be mailed to the Company’s shareholders entitled to vote at the Company Meeting so as to permit Company shareholders to exercise their right to make an Election prior to the Election Deadline.

(c)        The Form of Election shall be mailed to each Holder no less than thirty (30) Business Days prior to the Election Deadline or on such earlier date as the Company and CNB shall mutually agree.

(d)        Any Election shall have been made properly only if the Person authorized to receive Elections and to act as Exchange Agent under this Agreement, which Person shall be designated by CNB (the “Exchange

A-4

Agent”), pursuant to an agreement entered into prior to Closing shall have received, by 5:00 p.m. local time in the city in which the principal office of such Exchange Agent is located, on the date that is the day prior to the date of the Company Meeting (the “Election Deadline”), a Form of Election properly completed and signed; provided, however, that both the Exchange Agent and such agreement shall be reasonably acceptable to the Company.

(e)        Any Company shareholder may, at any time prior to the Election Deadline, change his or her Election by written notice received by the Exchange Agent prior to the Election Deadline accompanied by a properly completed and signed, revised Form of Election. If CNB, after consultation with the Exchange Agent and the Company, shall determine in its reasonable discretion that any Election is not properly made with respect to any shares of Company Common Stock, such Election shall be deemed to be not in effect, and the shares of Company Common Stock covered by such Election shall, for purposes hereof, be deemed to beNon-Election Shares, unless a proper Election is thereafter timely made.

(f)        Any Company shareholder may, at any time prior to the Election Deadline, revoke his or her Election by written notice received by the Exchange Agent prior to the Election Deadline. All Elections shall be revoked automatically if the Exchange Agent is notified in writing by CNB or the Company that this Agreement has been terminated in accordance with Article VIII.

(g)        If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name a certificate of shares of Company Common Stock (a “Company Stock Certificate”) surrendered pursuant toSection 2.03(o) is registered, it shall be a condition to such payment that such Company Stock Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall inform the Exchange Agent whether any transfer or other similar Taxes are required as a result of such payment to a Person other than the registered holder of such Company Stock Certificate, or establish to the reasonable satisfaction of the Exchange Agent that such Taxes are not payable. If such transfer or other similar Taxes are payable pursuant to the preceding sentence, then the Exchange Agent shall withhold and deduct from the Merger Consideration (including Stock Consideration and cash in lieu of fractional shares of CNB Common Stock) otherwise payable pursuant to this Agreement to the designated Person other than the registered holder such amounts as the Exchange Agent determines is necessary under applicable law based on the information supplied by the registered holder. The Exchange Agent (or, subsequent to thesix-month anniversary of the Effective Time, CNB) shall be entitled to deduct and withhold from the Merger Consideration (including Stock Consideration and cash in lieu of fractional shares of CNB Common Stock) otherwise payable pursuant to this Agreement to any holder of Company Common Stock such amounts as the Exchange Agent or CNB, as the case may be, is required to deduct, withhold and pay under the Code, or any provision of state, local or foreign Tax law, with respect to the making of such payment. To the extent that any amounts are so deducted, withheld and paid by the Exchange Agent or CNB, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Company Common Stock in respect of whom such deduction and withholding was made by the Exchange Agent or CNB, as the case may be.

(h)        After the Effective Time there shall be no further registration or transfers of shares of Company Common Stock. After the Effective Time, Company Stock Certificates that are presented to the Surviving Bank shall be cancelled and exchanged for the Merger Consideration in accordance with the procedures set forth in this Article II.

(i)        At any time following thesix-month anniversary of the Effective Time, CNB shall be entitled to require the Exchange Agent to deliver to it any remaining portion of the Merger Consideration not distributed to Holders that was deposited with the Exchange Agent at the Effective Time (the “Exchange Fund”) (including any interest received with respect thereto and other income resulting from investments by the Exchange Agent, as directed by CNB), and Holders shall be entitled to look only to CNB (subject to abandoned property, escheat or other similar laws) with respect to the Merger Consideration, any cash in lieu of fractional shares of CNB Common Stock and any dividends or other distributions with respect to CNB Common Stock payable upon due

A-5

surrender of their Company Stock Certificates, without any interest thereon. Notwithstanding the foregoing, neither CNB nor the Exchange Agent shall be liable to any Holder of a Company Stock Certificate for Merger Consideration (or dividends or distributions with respect thereto) or cash from the Exchange Fund in each case delivered to a public official pursuant to any applicable abandoned property, escheat or similar Laws.

(j)        In the event any Company Stock Certificates shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Company Stock Certificate(s) to be lost, stolen or destroyed and, if required by CNB or the Exchange Agent, the posting by such Person of a bond in such sum as CNB may reasonably direct as indemnity against any claim that may be made against it or the Surviving Bank with respect to such Company Stock Certificate(s), CNB shall cause the Exchange Agent to issue the Merger Consideration deliverable in respect of the shares of Company Common Stock represented by such lost, stolen or destroyed Company Stock Certificates.

(k)        No dividends or other distributions with respect to CNB Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Company Stock Certificate with respect to the shares of CNB Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to subsection (l) below, and all such dividends, other distributions and cash in lieu of fractional shares of CNB Common Stock shall be paid by CNB to the Exchange Agent and shall be included in the Exchange Fund, in each case until the surrender of such Company Stock Certificate in accordance with subsection (l) below. Subject to the effect of applicable abandoned property, escheat or similar Laws, following surrender of any such Company Stock Certificate there shall be paid to the Holder of a certificate for CNB Common Stock (a “CNB Stock Certificate”) representing whole shares of CNB Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of CNB Common Stock and the amount of any cash payable in lieu of a fractional share of CNB Common Stock to which such Holder is entitled pursuant to subsection (l), and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of CNB Common Stock. CNB shall make available to the Exchange Agent cash for these purposes, if necessary.

(l)        No CNB Stock Certificates representing fractional shares of CNB Common Stock shall be issued upon the surrender for exchange of Company Stock Certificates; no dividend or distribution by CNB shall relate to such fractional share interests; and such fractional share interests will not entitle the owner thereof to vote or to any rights as a shareholder of CNB. In lieu of any such fractional shares, each Holder of a Company Stock Certificate who would otherwise have been entitled to receive a fractional share interest in exchange for such Company Stock Certificate shall receive from the Exchange Agent an amount in cash equal to the product obtained by multiplying (A) the fractional share interest to which such Holder (after taking into account all shares of Company Common Stock held by such holder at the Effective Time) would otherwise be entitled by (B) the Closing CNB Share Value. Notwithstanding any other provision contained in this Agreement, funds utilized to acquire fractional shares as aforesaid shall be furnished by CNB on a timely basis and shall in no event be derived from or diminish the Cash Consideration available for distribution as part of the Merger Consideration.

(m)        CNB, in the exercise of its reasonable discretion, shall have the right to make all determinations, not inconsistent with the terms of this Agreement and without materially adversely affecting the rights and remedies of the Company or any shareholder thereof, governing (A) the validity of the Forms of Election and compliance by any Company shareholder with the Election procedures set forth herein, (B) the manner and extent to which Elections are to be taken into account in making the determinations prescribed bySection 2.03, (C) the issuance and delivery of CNB Stock Certificates into which shares of Company Common Stock are converted in the Merger and (D) the method of payment of cash for shares of Company Common Stock converted into the right to receive the Cash Consideration and cash in lieu of fractional shares of CNB Common Stock.

A-6

(n)        Prior to the Effective Time, CNB will deposit with the Exchange Agent certificates representing shares of CNB Common Stock sufficient to pay in a timely manner, and CNB shall instruct the Exchange Agent to timely pay, the aggregate Stock Consideration. In addition, prior to the Effective Time, CNB shall deposit with the Exchange Agent sufficient cash to permit prompt payment of the Cash Consideration and cash in lieu of fractional shares of CNB Common Stock, and CNB shall instruct the Exchange Agent to timely pay the Cash Consideration and cash in lieu of fractional shares of CNB Common Stock.

(o)        As soon as reasonably practicable, but in any event no later than five (5) Business Days after the Effective Time, CNB shall cause the Exchange Agent to mail to each holder of record of a Company Stock Certificate(s) which immediately prior to the Effective Time represented outstanding shares of Company Common Stock whose shares were converted into the right to receive the Merger Consideration pursuant toSection 2.01 and any cash in lieu of fractional shares of CNB Common Stock to be issued or paid in consideration therefor, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Company Stock Certificate(s) shall pass, only upon delivery of the Company Stock Certificate(s) (or affidavits of loss in lieu of such certificates)) (the “Letter of Transmittal”) to the Exchange Agent and shall be substantially in such form and have such other provisions as shall reasonably be determined by CNB and reasonably be acceptable to Company and (ii) instructions for use in surrendering the Company Stock Certificate(s) in exchange for the Merger Consideration and any cash in lieu of fractional shares of CNB Common Stock to be issued or paid in consideration therefor upon surrender of such certificate in accordance withSection 2.03(l) and any dividends or distributions to which such holder is entitled pursuant toSection 2.03(k).

(p)        Upon surrender to the Exchange Agent of its Company Stock Certificate(s), accompanied by a properly completed Letter of Transmittal, a Holder of Company Common Stock will be entitled to receive promptly after the Effective Time the Merger Consideration (elected or deemed elected by it, subject toSections 2.01 and2.02) in respect of the shares of Company Common Stock represented by its Company Stock Certificate. Until so surrendered, each such Company Stock Certificate shall represent after the Effective Time, for all purposes, only the right to receive the Merger Consideration and any cash in lieu of fractional shares of CNB Common Stock to be issued or paid in consideration therefor upon surrender of such certificate in accordance withSection 2.03(l) and any dividends or distributions to which such holder is entitled pursuant toSection 2.03(k).

Section 2.04    Certain Adjustments. If after the date hereof and on or prior to the Effective Time the outstanding shares of CNB Common Stock shall be changed into a different number of shares by reason of any reclassification, recapitalization or combination, stock split, reverse stock split, stock dividend or rights issued in respect of such stock, or any similar event shall occur (any such action, a “CNB Adjustment Event”), the Exchange Ratio shall be proportionately adjusted to provide to the holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such CNB Adjustment Event.

Section 2.05    Appraisal Rights; Dissenters’ Shares. Notwithstanding any other provision hereof, each outstanding share of Company Common Stock, the holder of which has perfected his or her right to dissent under applicable law and has not effectively withdrawn or lost such right as of the Effective Time (the “Dissenters’ Shares”), shall not be converted into or represent a right to receive the Merger Consideration hereunder, and the holder thereof shall be entitled only to such rights as are granted by applicable law. The Company shall give CNB prompt notice upon receipt by the Company of any such demands for payment of the fair value of shares of Company Common Stock and of withdrawals of such notice and any other related communications (any shareholder duly making such demand being hereinafter called a “Dissenting Shareholder”), and CNB shall have the right to participate in all discussions, negotiations and proceedings with respect to any such demands. The Company shall not, except with the prior written consent of CNB, voluntarily make any payment with respect to, or settle or offer to settle, any such demand for payment, or waive any failure to timely deliver a written demand for appraisal or the taking of any other action by such Dissenting Shareholder as may be necessary to perfect appraisal rights under applicable law. Any payments made in respect of Dissenters’ Shares shall be made by the Surviving Bank or CNB.

(e)        Except for those employees of the Company listed onSchedule 6.10(e)(i) of the Company Disclosure Schedule (the “Designated Company Employees”), CNB agrees to pay to each employee of the Company or any Subsidiary that is not covered by a written employment or severance agreement and either (i) not offered continued employment by CNB or CNB Bank after the Effective Time, or (ii) is terminated by CNB or any of its subsidiaries, without cause, within twelve (12) months following the Effective Time, a severance payment equal to two (2) weeks of his or her then current base salary multiplied by the number of total completed years of service with the Company or any Subsidiary; provided, however, that the minimum severance payment shall equal four (4) weeks of his or her base salary and the maximum severance payment shall not exceedtwenty-six (26) weeks of his or her base salary.

ANNEX B—NEW YORK LAW CONCERNING DISSENTERS’ RIGHTS

Section 6022 of the New York Banking Law

Procedure to enforce stockholder’s right to receive payment for shares

1. A stockholder intending to enforce his right under a section of this chapter to receive payment for his shares if the proposed corporate action referred to therein is taken shall file with the corporation, before the meeting of stockholders at which the action is submitted to a vote, or at such meeting but before the vote, written objection to the action. The objection shall include a statement that he intends to demand payment for his shares if the action is taken. Such objection is not required from any stockholder to whom the corporation did not give notice of such meeting in accordance with this chapter or where the proposed action is authorized by written consent of stockholders without a meeting.

2. Within ten days after the stockholders’ authorization date, which term as used in this section means the date on which the stockholders’ vote authorizing such action was taken, or the date on which such consent without a meeting was obtained from the requisite stockholders, the corporation shall give written notice of such authorization or consent by registered mail to each stockholder who filed written objection or from whom written objection was not required, excepting any who voted for or consented in writing to the proposed action.

3. Within twenty days after the giving of notice to him, any stockholder to whom the corporation was required to give such notice and who elects to dissent shall file with the corporation as written notice of such election, stating his name and residence address, the number and classes of shares as to which he dissents and a demand for payment of the fair value of his shares.

4. A stockholder may not dissent as to less than all of the shares, held by him of record, that he owns beneficially. A nominee or fiduciary may not dissent on behalf of any beneficial owner as to less than all of the shares of such owner held of record by such nominee or fiduciary.

5. Upon filing a notice of election to dissent, the stockholder shall cease to have any of the rights of a stockholder except the right to be paid the fair value of his shares and any other rights under this section. Withdrawal of a notice of election shall require the written consent of the corporation. If a notice of election is withdrawn, or the proposed corporate action is abandoned or rescinded, or a court shall determine that the stockholder is not entitled to receive payment for his shares, or the stockholder shall otherwise lose his dissenter’s rights, he shall not have the right to receive payment for his shares and he shall be reinstated to all his rights as a stockholder as of the filing of his notice of election, including any intervening preemptive rights and the right to payment of any intervening dividend or other distribution or, if any such rights have expired or any such dividend or distribution other than in cash has been completed, in lieu thereof, at the election of the corporation, the fair value thereof in cash as determined by the board as of the time of such expiration or completion, but without prejudice otherwise to any corporate proceedings that may have been taken in the interim.

6. At the time of filing the notice of election to dissent or within one month thereafter the stockholder shall submit the certificates representing his shares to the corporation, or to its transfer agent, which shall forthwith note conspicuously thereon that a notice of election has been filed and shall return the certificates to the stockholder or other person who submitted them on his behalf. Any stockholder who fails to submit his certificates for such notation as herein specified shall, at the option of the corporation exercised by written notice to him within forty-five days from the date of filing of such notice of election to dissent, lose his dissenter’s rights unless a court, for good cause shown, shall otherwise direct. Upon transfer of a certificate bearing such notation, each new certificate issued therefor shall bear a similar notation together with the name of the original dissenting holder of the shares and a transferee shall acquire no rights in the corporation except those which the original dissenting stockholder had after filing his notice of election.

7. Within seven days after the expiration of the period within which stockholders may file their notices of election to dissent, or within seven days after the proposed corporate action is consummated, whichever is later,

B-1

the corporation or, in the case of a merger, the receiving corporation, shall make a written offer by registered mail to each stockholder who has filed such notice of election to pay for his shares at a specified price which the corporation considers to be their fair value. Such offer shall be made at the same price per share to all dissenting stockholders of the same class, or if divided into series, of the same series and shall be accompanied by a balance sheet of the corporation whose shares the dissenting stockholder holds as of the latest available date, which shall not be earlier than twelve months before the making of such offer, and a profit and loss statement or statements for not less than a twelve month period ended on the date of such balance sheet or, if the corporation was not in existence throughout such twelve month period, for the portion thereof during which it was in existence. If within thirty days after the making of such offer, the corporation making the offer and any stockholder agree upon the price to be paid for his shares, payment therefor shall be made within sixty days after the making of such offer upon the surrender of the certificates representing such shares.

8. The following procedure shall apply if the corporation fails to make such offer within such period of seven days, or if it makes the offer and any dissenting stockholder or stockholders fail to agree with it within the period of thirty days thereafter upon the price to be paid for their shares:

(a) The corporation or, in the case of a merger, the receiving corporation shall, within twenty days after the expiration of whichever is applicable of the two periods last mentioned, institute a special proceeding in the supreme court in the judicial district in which the office of the corporation is located to determine the rights of dissenting stockholders and to fix the fair value of their shares.

(b) If the corporation fails to institute such proceeding within such period of twenty days, any dissenting stockholder may institute such proceeding for the same purpose not later than thirty days after the expiration of such twenty day period. If such proceeding is not instituted within such thirty day period, all dissenter’s rights shall be lost unless the supreme court, for good cause shown, shall otherwise direct.

(c) All dissenting stockholders, excepting those who, as provided in subdivision seven, have agreed with the corporation upon the price to be paid for their shares, shall be made parties to such proceeding, which shall have the effect of an action quasi in rem against their shares. The corporation shall serve a copy of the petition in such proceeding upon each dissenting stockholder who is a resident of this state in the manner provided by law for the service of a summons, and upon each nonresident dissenting stockholders either by registered mail and publication, or in such other manner as is permitted by law. The jurisdiction of the court shall be plenary and exclusive.

(d) The court shall determine whether each dissenting stockholder, as to whom the corporation requests the court to make such determination, is entitled to receive payment for his shares. If the corporation does not request any such determination or if the court finds that any dissenting stockholder is so entitled, it shall proceed to fix the value of the shares, which, for the purposes of this section, shall be the fair value as of the close of business on the day prior to the stockholders’ authorization date, excluding any appreciation or depreciation directly or indirectly induced by such corporate action or its proposal. The court may, if it so elects, appoint an appraiser to receive evidence and recommend a decision on the question of fair value. Such appraiser shall have the power, authority and duties specified in the order appointing him, or any amendment thereof.

(e) The final order in the proceeding shall be entered against the corporation in favor of each dissenting stockholder who is a party to the proceeding and is entitled thereto for the value of his shares so determined.

(f) The final order shall include an allowance for interest at such rate as the court finds to be equitable, from the stockholders’ authorization date to the date of payment. If the court finds that the refusal of any stockholder to accept the corporate offer of payment for his shares was arbitrary, vexatious or otherwise not in good faith, no interest shall be allowed to him.

(g) The costs and expenses of such proceeding shall be determined by the court and shall be assessed against the corporation, or, in the case of a merger, the receiving corporation, except that all or any part of such costs and expenses may be apportioned and assessed, as the court may determine, against any or all of the

B-2

dissenting stockholders who are parties to the proceeding if the court finds that their refusal to accept the corporate offer was arbitrary, vexatious or otherwise not in good faith. Such expenses shall include reasonable compensation for and the reasonable expenses of the appraiser, but shall exclude the fees and expenses of counsel for and experts employed by any party unless the court, in its discretion, awards such fees and expenses. In exercising such discretion, the court shall consider any of the following: (A) that the fair value of the shares as determined materially exceeds the amount which such corporation offered to pay; (B) that no offer was made by such corporation; and (C) that such corporation failed to institute the special proceeding within the period specified therefor.

(h) Within sixty days after final determination of the proceeding, the corporation or, in the case of a merger, the receiving corporation shall pay to each dissenting stockholder the amount found to be due him, upon surrender of the certificates representing his shares.

9. Shares acquired by the corporation upon the payment of the agreed value therefor or of the amount due under the final order, as provided in this section, shall be dealt with as provided in section five thousand fourteen, except that, in the case of a merger, they shall be disposed of as provided in the plan of merger or consolidation.

10. The enforcement by a stockholder of his right to receive payment for his shares in the manner provided herein shall exclude the enforcement by such stockholder of any other right to which he might otherwise be entitled by virtue of share ownership, except as provided in subdivision five, and except that this section shall not exclude the right of such stockholder to bring or maintain an appropriate action to obtain relief on the ground that such corporate action will be or is illegal or fraudulent as to him.

11. Except as otherwise expressly provided in this section, any notice to be given by a corporation to a stockholder under this section shall be given in the manner provided in section six thousand five.

ANNEX C—OPINION OF PIPER SANDLER & CO.

December 18, 2019

Board of Directors

Bank of Akron

46 Main Street

P.O. Box 420

Akron, NY 14001

Ladies and Gentlemen:

Bank of Akron (“Company”), CNB Financial Corporation (“CNB”) and CNB Bank, a wholly-owned subsidiary of CNB (“CNB Bank”) are proposing to enter into an Agreement and Plan of Merger (the “Agreement”) pursuant to which Company will merge with and into CNB Bank, with CNB Bank being the surviving bank (the “Merger”). Pursuant to the terms of the Agreement, at the Effective Time, each share of common stock, par value $3.00 per share, of Company (“Company Common Stock”) issued and outstanding immediately prior to the Effective Time, excluding certain shares of Company Common Stock as specified in the Agreement, will be converted, in accordance with and subject to the election, allocation and proration procedures set forth in the Agreement, into the right to receive the following, without interest: (i) for each share of Company Common Stock with respect to which a Cash Election has been effectively made and not revoked or lost pursuant to the Agreement, the right to receive cash from CNB in an amount equal to $215.00 (the “Cash Consideration”); or (ii) for each share of Company Common Stock with respect to which a Stock Election has been effectively made and not revoked or lost pursuant to the Agreement, the right to receive 6.6729 shares of CNB common stock, no par value (“CNB Common Stock” and such consideration, the “Stock Consideration”). The Cash Consideration and the Stock Consideration are collectively referred to herein as the “Merger Consideration.” The Agreement provides, generally, that seventy-five percent (75%) of the total number of shares of Company Common Stock shall be converted into the Stock Consideration and twenty-five percent (25%) of such shares of Company Common Stock shall be converted into the Cash Consideration in accordance with the election, allocation and proration procedures set forth in the Agreement. Capitalized terms used herein without definition shall 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 Merger Consideration to the holders of Company 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) a draft of the Agreement, dated December 18, 2019; (ii) certain publicly available financial statements and other historical financial information of Company that we deemed relevant; (iii) certain publicly available financial statements and other historical financial information of CNB that we

deemed relevant; (iv) certain internal financial projections for Company for the year ending December 31, 2019 as well as estimated long-term annual earnings per share and net income growth rates for the years ending December 31, 2020 through December 31, 2023 and estimated dividends per share for the years ending December 31, 2019 through December 31, 2023, as provided by the senior management of Company; (v) publicly available median analyst earnings per share and dividends per share estimates for CNB for the years ending December 31, 2019 and December 31, 2020, as adjusted by the senior management of CNB and its representatives to provide for a capital raising transaction expected to be completed by CNB in the first quarter of 2020, as well as an estimated long-term annual earnings per share growth rate for the years ending December 31, 2021 through December 31, 2023 and estimated dividends per share for the years ending December 31, 2021 through December 31, 2023, as provided by the senior management of CNB and its representatives; (vi) the pro forma financial impact of the Merger on CNB based on certain assumptions relating to purchase accounting adjustments, transaction expenses and cost savings, as well as an estimated earnings per share growth rate for Company for the years ending December 31, 2020 through December 31, 2023, as provided by the senior management of CNB; (vii) the publicly reported historical price and trading activity for Company Common Stock and CNB Common Stock, including a comparison of certain stock market information for Company Common Stock and CNB Common Stock and certain stock indices as well as publicly available information for certain other similar companies, the securities of which are publicly traded; (viii) a comparison of certain financial information for Company and CNB with similar financial institutions for which information is publicly available; (ix) the financial terms of certain recent business combinations in the bank and thrift industry (on a regional and nationwide basis), to the extent publicly available; (x) the current market environment generally and the banking environment in particular; and (xi) 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 senior management of Company the business, financial condition, results of operations and prospects of Company and held similar discussions with certain members of the senior management of CNB and its representatives regarding the business, financial condition, results of operations and prospects of CNB.

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 Company or CNB, 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 further have relied on the assurances of the respective senior managements of Company and CNB 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 undertake, 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 Company or CNB 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 Company or CNB. We did not make an independent evaluation of the adequacy of the allowance for loan losses of Company or CNB, or of the combined entity after the Merger, and we have not reviewed any individual credit files relating to Company or CNB. We have assumed, with your consent, that the respective allowances for loan losses for both Company and CNB are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity.

C-2

In preparing its analyses, Sandler O’Neill used certain internal financial projections for Company for the year ending December 31, 2019 as well as estimated long-term annual earnings per share and net income growth rates for the years ending December 31, 2020 through December 31, 2023 and estimated dividends per share for the years ending December 31, 2019 through December 31, 2023, as provided by the senior management of Company. In addition, Sandler O’Neill used publicly available median analyst earnings per share and dividends per share estimates for CNB for the years ending December 31, 2019 and December 31, 2020, as adjusted by the senior management of CNB and its representatives to provide for a capital raising transaction expected to be completed by CNB in the first quarter of 2020, as well as an estimated long-term annual earnings per share growth rate for the years ending December 31, 2021 through December 31, 2023 and estimated dividends per share for the years ending December 31, 2021 through December 31, 2023, as provided by the senior management of CNB and its representatives. Sandler O’Neill also received and used in its pro forma analyses certain assumptions relating to purchase accounting adjustments, transaction expenses and cost savings, as well as an estimated earnings per share growth rate for Company for the years ending December 31, 2020 through December 31, 2023, as provided by the senior management of CNB. With respect to the foregoing information, the respective senior managements of Company and CNB confirmed to us that such information reflected the best currently available estimates and judgments of those respective senior managements as to the future financial performance of Company and CNB, respectively, and the other matters covered thereby. 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 Company or CNB since the date of the most recent financial statements made available to us. We have assumed in all respects material to our analyses that Company and CNB will remain as going concerns for all periods relevant to our analyses.

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 Company, CNB, the Merger or any related transactions, and (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. Finally, with your consent, we have relied upon the advice that Company 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, regulatory, 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 values of Company Common Stock or CNB Common Stock at any time or what the value of CNB Common Stock will be once it is actually received by the holders of Company Common Stock.

C-3

We have acted as Company’s financial advisor in connection with the Merger and will receive a fee for our services, which fee is contingent upon closing of the Merger. We will also receive a fee for rendering this opinion, which opinion fee will be credited in full towards the advisory fee becoming payable to Sandler O’Neill upon closing of the Merger. Company 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. Sandler O’Neill has not provided any other investment banking services to Company in the two years preceding the date hereof. Sandler O’Neill did not provide any investment banking services to CNB in the two years preceding the date of this opinion. In the ordinary course of our business as a broker-dealer, we may purchase securities from and sell securities to Company, CNB and their respective affiliates. We may also actively trade the equity and debt securities of Company, CNB and their respective affiliates for our own account and for the accounts of our customers.

Our opinion is directed to the Board of Directors of Company in connection with its consideration of the Agreement and the Merger and does not constitute a recommendation to any shareholder of Company 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 Merger Consideration to the holders of Company Common Stock and does not address the underlying business decision of Company 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 Company or the effect of any other transaction in which Company 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 Company or CNB, 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 Merger Consideration is fair to the holders of Company Common Stock from a financial point of view.

Very truly yours,

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

The following is only a general summary of certain aspects of Pennsylvania law and CNB’sby-laws related to indemnification of directors and officers, and does not purport to be complete. It is qualified in its entirety by reference to the detailed provisions of the Pennsylvania Business Corporation Law of 1988, as amended, or BCL, and CNB’sby-laws cited herein.

Sections 1741 through 1743 of the BCL provide that a business corporation may indemnify directors and officers against liabilities they may incur in such capacities provided certain standards are met, including good faith and the belief that the particular action is in the best interests of the corporation. In general, this power to indemnify does not exist in the case of actions against a director or officer by or in the right of the corporation if the person entitled to indemnification shall have been adjudged to be liable to the corporation unless and only to the extent a court determines that the person is fairly and reasonably entitled to indemnification. A corporation is required to indemnify directors and officers against expenses they may incur in defending actions against them in such capacities if they are successful on the merits or otherwise in the defense of such actions. Section 1746 of the BCL provides that the foregoing provisions shall not be deemed exclusive of any other rights to which a person seeking indemnification may be entitled under, among other things, anyby-law provision, provided that no indemnification may be made in any case where the act or failure or act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness. Section 1747 of the BCL authorizes a corporation to purchase insurance for directors and other representatives. The foregoing statement is subject to the detailed provisions of Sections 1741 through 1850 of the BCL.

As permitted by the BCL, CNB’sby-laws, as amended and restated, provide that CNB shall, subject to certain authorizations and determinations, indemnify its directors and officers, including the advancement of expenses. Theby-laws contain the procedures pursuant to which such indemnification and advancement of expenses may be authorized and effectuated, including receipt of certain undertakings by the director or officer as a condition precedent to the advancement of expenses. Theby-laws, as amended and restated, provide, among other things, that indemnification shall not be made where the indemnification is expressly prohibited by law or where a final adjudication establishes that the director’s or officer’s conduct constitutes willful misconduct or recklessness or was based upon or attributable to the receipt from CNB of a personal benefit to which the director or officer was not legally entitled.

As permitted by the BCL, CNB maintains directors and officers liability insurance in amounts and on terms which CNB’s board of directors deems reasonable. In the ordinary course of business, CNB’s board of directors regularly reviews the scope and adequacy of such insurance coverage.

ITEM 22. UNDERTAKINGS

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 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 in 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 initialbona 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.

II-2

(4) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(6) (a)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.

(7) 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.

(8) That every prospectus (i) that is filed pursuant to paragraph (7) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the 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.

(8) 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 Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such issue.

II-3

(9) 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.

(10) 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 becomes effective.
