A requests that you vote by internet, by telephone, or by completing and
mailing the enclosed proxy card as soon as possible in the enclosed postage-paid envelope. This will not prevent you from voting online during the special meeting, but will assure that your vote is counted if you are unable to attend.

Abstentions and Broker Non-Votes

Only shares affirmatively voted for the ESSA merger proposal, the ESSA compensation proposal or the ESSA adjournment proposal, including shares represented by
properly executed proxies that do not contain voting instructions, will be counted as votes “FOR” the ESSA merger proposal, “FOR” the ESSA compensation proposal or “FOR” the ESSA adjournment
proposal, respectively.

Brokers who hold shares of ESSA 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 “non-routine” proposals without specific instructions from the customer. Proxies submitted by a broker that do
not exercise this voting authority are referred to as “broker non-votes.” It is expected that all proposals to be voted on at the ESSA special meeting will
be “non-routine” matters, and, as such, broker non-votes, if any, will not be counted as present and entitled to vote for purposes of
determining a quorum at the ESSA special meeting. If your bank, broker, trustee or other nominee holds your shares of ESSA common stock in “street name,” such entity will vote your shares of ESSA common stock only if you provide
instructions on how to vote by complying with the instructions provided to you by your bank, broker, trustee or other nominee with this joint proxy statement/prospectus.

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 will be counted for purposes of determining whether a quorum is present at the special meeting. Abstentions will have no effect on any of the
proposals.

Proxy Solicitation

If you are an ESSA shareholder, the enclosed proxy is solicited by and on behalf of the ESSA Board of Directors. ESSA will pay the expenses of soliciting
proxies to be voted at the special meeting, including any attorneys’ and accountants’ fees, except ESSA and CNB have
