On June 30, 2025, CNB and ESSA issued a joint press release announcing that they have received the requisite bank regulatory approvals and waivers from the Federal Deposit Insurance Corporation, the Pennsylvania Department of Banking and Securities and the Federal Reserve Bank of Philadelphia necessary for CNB to complete its acquisition of ESSA and ESSA Bank. CNB anticipates closing the transaction on July 23, 2025, subject to the satisfaction of customary closing conditions. A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
