 In the proposed merger, (i) ESSA will merge with and into CNB, with CNB as the surviving entity, and                                                                                                                                              
 (ii) ESSA Bank will merge with and into CNB Bank, with CNB Bank as the surviving entity. Each share of ESSA common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 
 0.8547 shares of CNB common stock.                                                                                                                                                                                                                |

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

1

ESSA Shareholders: You are being asked to vote on the following proposals: (i) to approve the merger agreement (the “ESSA merger proposal”), (ii) to approve, on an advisory (non-binding)basis, specified compensation that may become payable to the named executive officers of ESSA in connection with the merger (the “ESSA compensation proposal”) and (iii) to approve one or more adjournments or postponements of the ESSA special meeting, if necessary, to permit further solicitation of proxies if there are insufficient votes at the time of the ESSA special meeting, or at an adjournment or postponement of that meeting, to approve the ESSA merger proposal (the “ESSA adjournment proposal”).

| Q: | What will I receive in the merger? |

| A: | CNB Shareholders: 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 of the merger. 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. Following the merger, CNB common stock will continue to trade on the NASDAQ Stock Market, LLC (“NASDAQ”) under the symbol “CCNE.”                                                                                   |

ESSA Shareholders:If the ESSA merger proposal is approved and the merger is subsequently completed, ESSA shareholders will be entitled to receive 0.8547 shares of CNB common stock for each outstanding share of ESSA common stock held at the effective time of the merger and cash in lieu of fractional shares as described below. The value of the merger 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
