ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission (the “SEC”), using a “shelf” registration process for the delayed offering and sale of securities pursuant to Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”). Under the shelf process, we may, from time to time, sell any of the offered securities described in this prospectus in one or more offerings. Additionally, under the shelf process, in certain circumstances, we may provide a prospectus supplement that will contain specific information about the terms of a particular offering by us. We may also provide a prospectus supplement to add information to, or update or change information contained in, this prospectus.

We have filed with the SEC a registration statement on Form S-3, of which this prospectus is a part, under the Securities Act, with respect to the offered securities. This prospectus does not contain all of the information set forth in the registration statement, portions of which we have omitted as permitted by the rules and regulations of the SEC. Statements contained in this prospectus as to the contents of any contract or other document are not necessarily complete. You should refer to the copy of each contract or document filed as an exhibit to the registration statement for a complete description.

You should read this prospectus together with any additional information you may need to make your investment decision. You should also read and carefully consider the information in the documents we have referred you to in “Where You Can Find More Information” and “Incorporation of Certain Documents by Reference” below. Information incorporated by reference after the date of this prospectus may add, update or change information contained in this prospectus. Any information in such subsequent filings that is inconsistent with this prospectus will supersede the information in this prospectus or any earlier prospectus supplement.

As used in this prospectus, unless the context otherwise requires, the terms “we,” “us,” “our” and “the Company” mean, collectively, CNB Financial Corporation and its subsidiaries and their predecessors. In this prospectus, we sometimes refer to the common stock and preferred stock collectively as the “offered securities.”

CAUTIONARY NOTE ABOUT FORWARD-LOOKING STATEMENTS

This prospectus and the information incorporated by reference in it, as well as any prospectus supplement that accompanies it, include forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, with respect to the financial condition, liquidity, results of operations, future performance and our business. These forward-looking statements are intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995. Forward-looking statements are those that are not historical facts. Forward-looking statements include statements with respect to beliefs, plans, objectives, goals, expectations, anticipations, estimates and intentions that are subject to significant risks and uncertainties and are subject to change based on various factors (some of which are beyond our control). Forward-looking statements often include the words “believes,” “expects,” “anticipates,” “estimates,” “forecasts,” “intends,” “plans,” “targets,” “potentially,” “probably,” “projects,” “outlook” or similar expressions or future conditional verbs such as “may,” “will,” “should,” “would” and “could.” Such known and unknown risks, uncertainties and other factors that could cause the actual results to differ materially from the statements, include, but are not limited to, (i) changes in general business, industry or economic conditions or competition; (ii) changes in any applicable law, rule, regulation, policy, guideline or practice governing or affecting financial holding companies and their subsidiaries or with respect to tax or accounting principles or otherwise; (iii) adverse changes or conditions in capital and financial markets; (iv) changes in interest rates; (v) higher than expected costs or other difficulties related to integration of combined or merged businesses; (vi) the inability to realize expected cost savings or achieve other anticipated benefits in connection with business combinations and other acquisitions; (vii) changes in the quality or composition of our loan and investment portfolios; (viii) adequacy of loan loss reserves; (ix) increased competition; (x) loss of certain key officers; (xi) continued relationships with major customers; (xii) deposit attrition; (xiii) rapidly changing technology; (xiv) unanticipated regulatory or judicial proceedings and liabilities and other costs; (xv) changes in the cost of funds, demand for loan products or demand for financial services; and (xvi) other economic, competitive, governmental or technological factors affecting our operations, markets, products, services and prices. Such developments could have an adverse impact on our financial position and our results of operations.

The forward-looking statements are based upon management’s beliefs and assumptions. Any forward-looking statement made herein speaks only as of the date on which it is made. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law.

ABOUT CNB FINANCIAL CORPORATION

We are a bank holding company and a financial holding company registered under the Bank Holding Company Act of 1956, as amended. We were incorporated under the laws of the Commonwealth of Pennsylvania in 1983 for the purpose of engaging in the business of a financial holding company. On April 26, 1984, we acquired all of the outstanding capital stock of County National Bank, a national banking chartered institution. In December of 2006, County National Bank changed its name to CNB Bank (the “Bank”) and became a state bank chartered in Pennsylvania and subject to regulation by the Pennsylvania Department of Banking and the Federal Deposit Insurance Corporation.

We are subject to regulation, supervision and examination by the Board of Governors of the Federal Reserve System. In general, we are limited to owning or controlling banks and engaging in such other activities as are properly incident thereto. In addition to the Bank, we have three other subsidiaries, CNB Securities Corporation, CNB Insurance Agency and Holiday Financial Services Corporation. CNB Securities Corporation, incorporated in Delaware, maintains investments in debt and equity securities. CNB Insurance Agency, incorporated in Pennsylvania, provides for the sale of nonproprietary annuities and other insurance products. Holiday Financial Services Corporation, incorporated in Pennsylvania, offers small balance unsecured loans and secured loans, primarily collateralized by automobiles and equipment, to borrowers with higher risk characteristics.

We do not currently engage in any operating business activities, other than the ownership and management of CNB Bank, CNB Securities Corporation, CNB Insurance Agency, and Holiday Financial Services Corporation.

The Bank was incorporated in 1934 and is chartered in the Commonwealth of Pennsylvania. ERIEBANK, a division of CNB Bank, began operations in 2005.

Farmers Citizens Bank served the central Ohio markets of Bucyrus, Cardington, Fredericktown, Mount Hope and Shiloh, as well as the markets of Worthington and Upper Arlington in the greater Columbus, Ohio area, with 8 branch locations. We continue to operate these branch locations as FCBank, a division of CNB Bank. In July 2016, we acquired Lake National Bank of Mentor, Ohio. We operate the two former Lake National Bank branches in Mentor, Ohio as part of the ERIEBANK division of CNB Bank. Bank on Buffalo, a division of CNB Bank, began operations in November 2016 with the opening of a loan production office in Buffalo, New York.

The Bank has full service branch offices and loan production offices located in various communities in its market area. The Bank’s primary market area includes the Pennsylvania counties of Cambria, Cameron, Centre, Clearfield, Crawford, Elk, Indiana, Jefferson, and McKean. As ERIEBANK, a division of CNB Bank, the Bank operates in the Pennsylvania counties of Crawford, Erie, and Warren, and in the Ohio counties of Lake and Ashtabula. As FCBank, a division of CNB Bank, the Bank operates in the Ohio counties of Crawford, Richland, Ashland, Wayne, Marion, Morrow, Knox, Holmes, Delaware, and Franklin. As Bank on Buffalo, a division of CNB Bank, the Bank operates in Erie County, New York.

The Bank is a full service bank engaging in a full range of banking activities and services for individual, business, governmental and institutional customers. These activities and services principally include checking, savings, and time deposit accounts; real estate, commercial, industrial, residential and consumer loans; and a variety of other specialized financial services.

RISK FACTORS

Investing in our securities involves significant risks. Before making an investment decision, you should carefully consider the risks and other information we include or incorporate by reference in this prospectus and any prospectus supplement. In particular, you should consider the risk factors under the heading “Risk Factors” included in our most recent Annual Report on Form 10-K, as may be revised or supplemented by our subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, each of which are on file with the SEC and are incorporated herein by reference, and which may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future. The risks and uncertainties we have described are not the only ones facing our company. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also affect our business operations. Additional risk factors may be included in a prospectus supplement relating to a particular offering of securities. For additional information, please see the sources described in “Where You Can Find More Information.”

RATIO OF EARNINGS TO COMBINED FIXED CHARGES AND PREFERRED

STOCK DIVIDENDS

The following table sets forth our historical consolidated ratio of earnings to fixed charges and preferred stock dividends for the periods shown. No shares of preferred stock were outstanding during any annual or quarterly period reported below and no preferred dividends were paid.

	Nine Months Ended September 30,		Year ended December 31,
Ratio of Earnings to Combined Fixed Charges and Preferred Stock Dividends	2016		2015		2014		2013		2012		2011

For purposes of computing these ratios:

• earnings consist of net income from continuing operations before income taxes, plus applicable fixed charges;

The ratios are presented in two separate calculations – one including, and one excluding, interest expense on deposits.

USE OF PROCEEDS

Unless otherwise indicated in the applicable prospectus supplement, we expect to use the net proceeds from the sale of offered securities for general corporate purposes, including:

• expansion of the business;

• investments in our subsidiary bank as regulatory capital to fund growth;

• financing of possible acquisitions;

• refinancing, reduction or repayment of debt; and

• investments at the holding company level.

The prospectus supplement with respect to an offering of offered securities may identify different or additional uses for the proceeds of that offering.

Pending the application of the net proceeds, we expect to temporarily invest the proceeds from the sale of offered securities in short-term obligations.

THE SECURITIES WE MAY OFFER

The descriptions of the securities contained in this prospectus, together with the applicable prospectus supplements, summarize certain material terms and provisions of the various types of securities that we may offer. The particular material terms of the securities offered by a prospectus supplement will be described in that prospectus supplement. If indicated in the applicable prospectus supplement, the terms of the offered securities may differ from the terms summarized below. The prospectus supplement will also contain information, where applicable, about material U.S. federal income tax considerations relating to the offered securities, and the securities exchange, if any, on which the offered securities will be listed. The descriptions herein and in the applicable prospectus supplement do not contain all of the information that you may find useful or that may be important to you. You should refer to the provisions of the actual documents whose terms are summarized herein and in the applicable prospectus supplement, because those documents, and not the summaries, define your rights as holders of the relevant securities. For more information, please review the forms of these documents, which are or will be filed with the SEC and will be available as described under the heading “Where You Can Find More Information” above.

We may offer and sell from time to time, in one or more offerings, common stock and/or preferred stock.

7

DESCRIPTION OF COMMON STOCK

The following description is a general summary of the terms of our common stock. The description below does not purport to be complete and is subject to and qualified in its entirety by reference to our amended and restated articles of incorporation and by-laws, as amended and restated. The description below does not contain all of the information that you might find useful or that might be important to you. You should refer to the provisions of our amended and restated articles of incorporation and by-laws, as amended and restated, because they, and not the summaries, define the rights of holders of shares of our common stock. You can obtain copies of our amended and restated articles of incorporation and by-laws, as amended and restated, by following the directions under the heading “Where You Can Find More Information.”

General

Our amended and restated articles of incorporation authorize us to issue 50,000,000 shares of stock, no par value. As of December 30, 2016, there were 14,473,482 shares of common stock issued and there were no outstanding options exercisable for shares of our common stock.

Each share of our common stock has the same relative rights and is identical in all respects to each other share of our common stock. Our common stock is non-withdrawable capital, is not of an insurable type and is not insured by the Federal Deposit Insurance Corporation or any other governmental entity.

Voting Rights

Holders of our common stock are entitled to one vote per share on each matter properly submitted to shareholders for their vote, including the election of directors. Holders of our common stock do not have the right to cumulate their votes for the election of directors. Subject to certain exceptions, whenever any corporate action is to be taken by a vote of the shareholders, it will be authorized by the affirmative vote of a majority of the votes cast by all shareholders entitled to vote thereon. Directors receiving the highest number of votes shall be elected.

Liquidation Rights

The holders of our common stock, together with the holders of any class or series of stock entitled to participate with the holders of our common stock in the distribution of assets in the event of any liquidation, dissolution or winding-up of us, whether voluntary or involuntary, will be entitled to participate equally in the distribution of any of our assets remaining after we have paid, or provided for the payment of, all of our debts and liabilities and after we have paid, or set aside for payment to, the holders of any class of stock having preference over the common stock in the event of a liquidation, dissolution or winding-up the full preferential amounts to which they are entitled.

Dividends

The holders of our common stock and any class or series of stock entitled to participate with the holders of our common stock are entitled to receive dividends declared by our board of directors out of any assets legally available for distribution. We may not pay dividends or other distributions unless we have paid, declared or set aside all accumulated dividends and any sinking fund, retirement fund or other retirement payments on any class of stock having preference as to payments of dividends over our common stock. As a holding company, our ability to pay distributions is affected by the ability of our subsidiaries to pay dividends. The ability of our bank subsidiary, and our ability, to pay dividends in the future is, and could in the future be further, influenced by bank regulatory requirements and capital guidelines.

Miscellaneous

The holders of our common stock have no preemptive or conversion rights for any shares that may be issued. Our common stock is not subject to additional calls or assessments, and all shares of our common stock currently outstanding are fully paid and nonassessable. All shares of common stock offered pursuant to a prospectus supplement, or issuable upon conversion, exchange or exercise of any convertible securities, will, when issued, be fully paid and nonassessable, which means that the full purchase price of the shares will have been paid and the holders of the shares will not be assessed any additional monies for the shares.

Certain Important Charter Provisions

Our by-laws, as amended and restated, provide for the division of our board of directors into three classes of directors, each class as nearly as equal as possible, with each serving staggered terms. Any amendment to our by-laws must be approved by 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. Additionally, our amended and restated articles of incorporation provide that the affirmative vote of at least 66% of the outstanding shares of each class entitled to vote is required to effect a merger or consolidation of the Company into another company that is not a wholly owned subsidiary of the Company.

8

Some of the foregoing provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of us.

Since the terms of our amended and restated articles of incorporation and by-laws, as amended and restated, may differ from the general information we are providing, you should only rely on the actual provisions of our amended and restated articles of incorporation and by-laws. If you would like to read our amended and restated articles of incorporation and by-laws, you may request a copy from us by following the directions under the heading “Where You Can Find More Information.”

NASDAQ Stock Market Listing

Our common stock is traded on the NASDAQ Stock Market under the symbol “CCNE.”

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC.

DESCRIPTION OF PREFERRED STOCK

The following description is a general summary of the terms of the preferred stock which we may issue. The description below and in any prospectus supplement does not purport to be complete and is subject to and qualified in its entirety by reference to our amended and restated articles of incorporation and the applicable certificate of designations designating the terms of the related series of preferred stock and our by-laws, as amended and restated, each of which we will make available upon request. The descriptions herein and in the applicable prospectus supplement do not contain all of the information that you may find useful or that may be important to you. You should refer to the provisions of our amended and restated articles of incorporation, the applicable certificate of designations and our by-laws, as amended and restated, because they, and not the summaries, define your rights as holders of shares of our preferred stock.

General

We are authorized to issue 50,000,000 shares of stock, no par value. Our amended and restated articles of incorporation, subject to limitations prescribed in such articles and subject to limitations prescribed by Pennsylvania law, authorize the board of directors, from time to time by resolution and without further shareholder action, to provide for the issuance of shares of preferred stock, in one or more series, and to fix the designation, powers, preferences and other rights of the shares and to fix the qualifications, limitations and restrictions thereof. As a result of its broad discretion with respect to the creation and issuance of preferred stock without shareholder approval, the board of directors could adversely affect the voting power of the holders of common stock and, by issuing shares of preferred stock with certain voting, conversion and/or redemption rights, could discourage any attempt to obtain control of us.

Terms of the Preferred Stock That We May Offer and Sell to You

You should refer to the prospectus supplement relating to the class or series of preferred stock being offered for the specific terms of that class or series, including:

• the title and stated value of the preferred stock being offered;

• the number of shares of preferred stock being offered, their liquidation preference per share and their purchase price;

10

Ranking

Unless otherwise specified in the applicable prospectus supplement, the preferred stock will, with respect to distribution rights and rights upon liquidation, dissolution or winding up of our affairs, rank:

• senior to all classes or series of our common stock and to all equity securities the terms of which specifically provide that the equity securities rank junior to the preferred stock being offered;

• equally with all equity securities issued by us other than those referred to in the first and last bullet points of this subheading; and

• junior to all equity securities issued by us the terms of which specifically provide that the equity securities rank senior to the preferred stock being offered.

For purposes of this subheading, the term “equity securities” does not include convertible debt securities.

Distributions

Holders of the preferred stock of each series will be entitled to receive, when, as and if declared by our board of directors, out of our assets legally available for payment to shareholders, cash distributions, or distributions in kind or in other property if expressly permitted and described in the applicable prospectus supplement, at the rates and on the dates as we will set forth in the applicable prospectus supplement. We will pay each distribution to holders of record as they appear on our stock transfer books on the record dates determined by our board of directors.

Distributions on any class or series of preferred stock, if cumulative, will be cumulative from and after the date set forth in the applicable prospectus supplement. If our board of directors fails to declare a distribution payable on a distribution payment date on any class or series of preferred stock for which distributions are non-cumulative, then the holders of that class or series of preferred stock will have no right to receive a distribution in respect of the distribution period ending on that distribution payment date, and we will have no obligation to pay the distribution accumulated for that period, whether or not distributions on that series are declared payable on any future distribution payment date.

If any shares of the preferred stock of any class or series are outstanding, no full dividends will be declared or paid or set apart for payment on our preferred stock of any other class or series ranking, as to dividends, equally with or junior to the preferred stock of the class or series for any period unless all required dividends are paid. The phrase “all required dividends are paid” when used in this prospectus with respect to class or series of preferred stock means that:

• if the class or series of preferred stock has a cumulative dividend, full cumulative dividends on the preferred stock of the class or series have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment is set apart for payment for all past dividend periods and the then current dividend period; or

• if the class or series of preferred stock does not have a cumulative dividend, full dividends on the preferred stock of the class or series have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment is set apart for the payment for the then current dividend period.

When dividends are not paid in full, or a sum sufficient for the full payment is not so set apart, upon the shares of preferred stock of any class or series and the shares of any other class or series of preferred stock ranking equally as to dividends with the preferred stock of the class or series, all dividends declared upon shares of preferred stock of the class or series and any other class or series of preferred stock ranking equally as to dividends with the preferred stock will be declared equally so that the amount of dividends declared per share on the preferred stock of the class or series and the other class or series of preferred stock will in all cases bear to each other the same ratio that accrued and unpaid dividends per share on the shares of preferred stock of the class or series, which will not include any accumulation in respect of unpaid dividends for prior dividend periods if the preferred stock does not have cumulative dividend, and the other class or series of preferred stock bear to each other. No interest or sum of money in lieu of interest will be payable in respect of any dividend payment or payments on preferred stock of the class or series which may be in arrears.

Except as provided in the immediately preceding paragraph, unless all required dividends are paid, no dividends, other than in common stock or other stock ranking junior to the preferred stock of the class or series as to dividends and upon liquidation, dissolution or winding-up of us, will be declared or paid or set aside for payment or other distribution will be declared or made upon the common stock or any of our other stock ranking junior or equally with the preferred stock of the class or series as to dividends or upon liquidation, nor will any common stock or any of our other capital stock ranking junior to or equally with preferred stock of the class or series as to dividends or upon liquidation, dissolution or winding-up of us be redeemed, purchased or otherwise acquired for any consideration, or any moneys be paid to or made available for a sinking fund for the redemption of any shares of any stock, by us except by conversion into or exchange for our other stock ranking junior to the preferred stock of the class or series as to dividends and upon liquidation, dissolution or winding-up of us.

11

Any dividend payment made on shares of a class or series of preferred stock will first be credited against the earliest accrued but unpaid dividend due with respect to shares of the class or series which remains payable.

Redemption

If so provided in the applicable prospectus supplement, the preferred stock will be subject to mandatory redemption or redemption at our option, in whole or in part, in each case upon the terms, at the times and at the redemption prices set forth in the prospectus supplement.

The prospectus supplement relating to a class or series of preferred stock that is subject to mandatory redemption will specify the number of shares of the preferred stock that will be redeemed by us in each year commencing after a date to be specified, at a redemption price per share to be specified, together with an amount equal to all accumulated and unpaid dividends thereon, which will not, if the preferred stock does not have a cumulative dividend, include an accumulation in respect of unpaid dividends for prior dividends periods, to the date of redemption. The redemption price may be payable in cash or other property, as specified in the applicable prospectus supplement. If the redemption price for preferred stock of any series is payable only from the net proceeds of the issuance of our stock, the terms of the preferred stock may provide that, if no stock will have been issued or to the extent the net proceeds from any issuance are insufficient to pay in full the aggregate redemption price then due, the preferred stock will automatically and mandatorily be converted into shares of our applicable stock pursuant to conversion provisions specified in the applicable prospectus supplement.

Notwithstanding the foregoing, unless provided otherwise for any class or series of preferred stock, unless all required dividends are paid:

• no shares of the applicable class or series of preferred stock will be redeemed unless all outstanding shares of preferred stock of the class or series are simultaneously redeemed; and

• we will not purchase or otherwise acquire directly or indirectly any shares of the applicable class or series of preferred stock, except by conversion into or exchange for our stock ranking junior to the preferred stock of the class or series as to dividends and upon liquidation, dissolution or winding-up of us;

provided, however, that the above restrictions will not prevent the purchase or acquisition of shares of preferred stock of the class or series pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding shares of preferred stock of the class or series.

Liquidation Preference

Upon any voluntary or involuntary liquidation, dissolution or winding up of our affairs, then, before any distribution or payment will be made to the holders of any common stock or any other class or series of shares of our capital stock ranking junior to the preferred stock in the distribution of assets upon any liquidation, dissolution or winding up of our affairs, the holders of each series or class of preferred stock will be entitled to receive out of our assets legally available for distribution to shareholders liquidating distributions in the amount of the liquidation preference set forth in the applicable prospectus supplement, plus an amount equal to all accumulated and unpaid distributions. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of shares of preferred stock will have no right or claim to any of our remaining assets. If, upon the voluntary or involuntary liquidation, dissolution or winding up, our available assets are insufficient to pay the amount of the liquidating distributions on all outstanding shares of preferred stock and the corresponding amounts payable on all shares of other classes or series of shares of our capital stock ranking equally with the preferred stock in the distribution of assets, then the holders of the preferred stock and all other classes or series of shares of capital stock will share ratably in any distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled.

If liquidating distributions will have been made in full to all holders of preferred stock, our remaining assets will be distributed among the holders of any other classes or series of shares of capital stock ranking junior to the preferred stock upon liquidation, dissolution or winding up, according to their respective rights and preferences and in each case according to their respective number of shares.

For those purposes, the consolidation or merger of us with or into any other corporation, trust or entity, or the sale, lease or conveyance of all or substantially all of our property or business, will not be deemed to constitute a liquidation, dissolution or winding up of our affairs.

Voting Rights

Holders of preferred stock will not have any voting rights, except as set forth below or as otherwise from time to time required by law, or as otherwise provided in the articles of amendment or the resolutions establishing such series and as indicated in the applicable prospectus supplement.

12

Conversion Rights

The terms and conditions, if any, upon which any class or series of preferred stock are convertible into or exchangeable for our other securities or rights or those of other issuers, including, without limitation, common stock, debt securities, trust preferred securities or another series of preferred stock, or any combination of the foregoing, will be set forth in the applicable prospectus supplement relating to the preferred stock. The terms will include the name of the issuer of the other securities or rights and the number or principal amount of the securities or rights into which the shares of preferred stock are convertible or exchangeable, the conversion or exchange price or rate or the manner of calculating the price, the conversion or exchange date(s) or period(s), provisions as to whether conversion or exchange will be at the option of the holders of the preferred stock or at our or other issuer’s option, the events requiring an adjustment of the conversion or exchange price or rate and provisions affecting conversion or exchange in the event of the redemption of the series of preferred stock.

Transfer Agent and Registrar

We will identify the transfer agent and registrar for any series of preferred stock offered by this prospectus in a prospectus supplement.

13

PLAN OF DISTRIBUTION

We may sell the securities offered by this prospectus in any one or more of the following ways from time to time:

• directly to investors, including through a specific bidding, auction or other process;

• to investors through agents;

• directly to agents;

• to or through brokers or dealers;

• to the public through underwriting syndicates led by one or more managing underwriters;

• to one or more underwriters acting alone for resale to investors or to the public; or

• through a combination of any such methods of sale.

We may also sell the securities offered by this prospectus in “at the market offerings” within the meaning of Rule 415(a)(4) of the Securities Act, to or through a distribution agent or market maker, or into an existing trading market, on an exchange or otherwise.

The prospectus supplement related to a particular offering will set forth the terms of the offering and the method of distribution and will identify any firms acting as underwriters, dealers or agents in connection with the offering, including:

• the name or names of any underwriters, dealers or agents;

• the purchase price of the securities and the proceeds to us from the sale;

• any over-allotment options under which the underwriters may purchase additional securities from us;

• any underwriting discounts and other items constituting compensation to underwriters, dealers or agents;

• any public offering price;

• any discounts or concessions allowed or reallowed or paid to dealers; or

• any securities exchange or market on which the securities offered in the prospectus supplement may be listed.

Only those underwriters identified in such prospectus supplement are deemed to be underwriters in connection with the securities offered in the prospectus supplement. Any underwritten offering may be on a best efforts or a firm commitment basis.

The distribution of the securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, at varying prices determined at the time of sale, or at prices determined as the applicable prospectus supplement specifies. The securities may be sold through a rights offering, forward contracts or similar arrangements.

In connection with the sale of the securities, underwriters, dealers or agents may be deemed to have received compensation from us in the form of underwriting discounts or commissions and also may receive commissions from securities purchasers for whom they may act as agent. Underwriters may sell the securities to or through dealers, and the dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they may act as agent.

We will provide in the applicable prospectus supplement information regarding any underwriting discounts or other compensation that we pay to underwriters or agents in connection with the securities offering, and any discounts, concessions or commissions which underwriters allow to dealers. Underwriters, dealers and agents participating in the securities distribution may be deemed to be underwriters, and any discounts and commissions they receive and any profit they realize on the sale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act. Underwriters and their controlling persons, dealers and agents may be entitled, under agreements entered into with us, to indemnification against and contribution toward specific civil liabilities, including liabilities under the Securities Act.

Unless otherwise specified in the related prospectus supplement, each series of securities will be a new issue with no established trading market, other than shares of our common stock, which are listed on the NASDAQ Stock Market. We may elect to list any series of preferred stock on an exchange, but we are not obligated to do so. It is possible that one or more underwriters may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of, or the trading market for, any offered securities.

In connection with an offering, the underwriters may purchase and sell securities in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of securities than they are required to purchase in an offering. Stabilizing transactions consist of bids or purchases made for the purpose of preventing or retarding a decline in the market price of the securities while an offering is in progress. The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a

14

portion of the underwriting discount received by it because the underwriters have repurchased securities sold by or for the account of that underwriter in stabilizing or short-covering transactions. These activities by the underwriters may stabilize, maintain or otherwise affect the market price of the securities. As a result, the price of the securities may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. Underwriters may engage in over-allotment. If any underwriters create a short position in the securities in an offering in which they sell more securities than are set forth on the cover page of the applicable prospectus supplement, the underwriters may reduce that short position by purchasing the securities in the open market.

Underwriters, dealers or agents that participate in the offer of securities, or their affiliates or associates, may be customers of, have engaged or engage in transactions with, and perform services for, us or our affiliates in the ordinary course of business for which they may have received or receive customary fees and reimbursement of expenses.

15

In connection with particular offerings of securities in the future, the validity of any securities offered by this prospectus from time to time will be passed upon for us by Hogan Lovells US LLP. If legal matters in connection with offerings made pursuant to this prospectus are passed upon by counsel to underwriters, dealers or agents, if any, such counsel will be named in the prospectus supplement related to such offering.

Item 15. Indemnification of Officers and Directors.

Sections 1741 through 1743 of the Pennsylvania Business Corporation Law of 1988, as amended (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, any by-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, the by-laws of the registrant, as amended and restated, provide that the registrant shall, subject to certain authorizations and determinations, indemnify its directors and officers, including the advancement of expenses. The by-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. The by-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 the CNB Financial Corporation of a personal benefit to which the director or officer was not legally entitled.

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

Any underwriting agreement that we might enter into will provide for indemnification by any underwriters of us, our directors, our officers who sign the registration statement and our controlling persons for some liabilities, including liabilities arising under the Securities Act.

Item 16. Exhibits

The Exhibit Index included herewith is incorporated herein by reference.

II-1

Item 17. 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 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

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

provided, however, that paragraphs (i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

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

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

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) 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.

II-2

(6) 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 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) 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 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.

(8) That for purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4), or 497(h) under the Securities Act of 1933 shall be deemed to be part of this registration statement as of the time it was declared effective.

(9) That for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus 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.

Exhibit 5.1

January 6, 2017

Board of Directors

CNB Financial Corporation

1 South Second Street, P.O. Box 42

Clearfield, PA 16830

Ladies and Gentlemen:

We are acting as counsel to CNB Financial Corporation, a Pennsylvania corporation (the “Company”), in connection with its registration statement on Form S-3 (the “Registration Statement”), filed with the Securities and Exchange Commission relating to the proposed public offering of up to $150,000,000 in aggregate amount of one or more series of the following securities of the Company: (i) shares of preferred stock, no par value per share (the “Preferred Shares”), and (ii) shares of common stock, no par value per share (the “Common Shares” and, together with the Preferred Shares, the “Securities”), all of which may be sold from time to time and on a delayed or continuous basis, as set forth in the prospectus which forms a part of the Registration Statement, and as to be set forth in one or more supplements to the prospectus.

For purposes of this opinion letter, we have examined copies of such agreements, instruments and documents as we have deemed an appropriate basis on which to render the opinions hereinafter expressed. In our examination of the aforesaid documents, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the accuracy and completeness of all documents submitted to us, the authenticity of all original documents, and the conformity to authentic original documents of all documents submitted to us as copies (including pdfs).

This opinion letter is given, and all statements herein are made, in the context of the foregoing.

For purposes of this opinion letter, we have assumed that (i) the issuance, sale, amount and terms of any Securities of the Company to be offered from time to time will have been duly authorized and established by proper action of the board of directors of the Company or a duly authorized committee of such board (“Board Action”) consistent with the procedures and terms described in the Registration Statement and in accordance with the Company’s charter and bylaws and applicable Pennsylvania corporate law, in a manner that does not violate any law, government or court-imposed order or restriction or agreement or instrument then binding on the Company or otherwise impair the legal or binding nature of the obligations represented by the applicable Securities; (ii) at the time of offer, issuance and sale of any Securities, the Registration Statement will have been declared effective under the Securities Act of 1933, as amended (the “Act”), and no stop order suspending its effectiveness will have been issued and remain in effect; (iii) prior to any issuance of Preferred Shares, appropriate certificates of designation will be accepted for record by the Office of the Secretary of the Commonwealth of Pennsylvania; (iv) if being sold by the issuer thereof, the Securities will be delivered against payment of valid consideration therefor and in accordance with the terms of the applicable Board Action authorizing such sale and any applicable underwriting agreement or purchase agreement and as contemplated by the Registration Statement and/or the applicable prospectus supplement; and (v) the Company will remain a Pennsylvania corporation.

This opinion letter is based as to matters of law solely on the applicable provisions of the Pennsylvania Business Corporation Law of 1988, as currently in effect. We express no opinion herein as to any other statutes, rules, or regulations (and in particular, we express no opinion as to any effect that such other statutes, rules or regulations may have on the opinions expressed herein).

Based upon, subject to and limited by the foregoing, we are of the opinion that:

(a) The Preferred Shares, upon due execution and delivery on behalf of the Company of certificates therefor, including global certificates, or the entry of the issuance thereof in the books and records of the Company, as the case may be, will be validly issued, fully paid and nonassessable.

(b) The Common Shares (including any Common Shares duly issued upon the exchange or conversion of Preferred Shares that are exchangeable for or convertible into Common Shares and receipt by the Company of any additional consideration payable upon such conversion or exchange), upon due execution and delivery on behalf of the Company of certificates therefor, including global certificates, or the entry of the issuance thereof in the books and records of the Company, as the case may be, will be validly issued, fully paid and nonassessable.
