On April 21, 2026, Citizens and Peoples announced an agreement to merge and become one company. The merger is expected to close during the second half of 2026, subject to the satisfaction of customary closing conditions, including regulatory approvals and the approval of Citizens’ shareholders. Customers should continue banking normally as there are no immediate changes to accounts or services.

After the merger, and until Citizens converts to Peoples’ systems during the first half of 2027, Citizens Bank of Kentucky will continue to operate under the Citizens Bank of Kentucky name, and its customers will continue to bank as normal – products and services will generally not be affected.

Citizens Bank systems, locations, products, and services will officially convert to Peoples Bank systems, locations, products, and services. You will receive communication regarding account transitions, digital banking updates, branch information, and additional support resources.

Together, Citizens Bank of Kentucky and Peoples Bank can make a bigger impact. From providing more services and locations for our clients to combining our charitable donations and volunteer hours, we believe our shared values will make a meaningful difference in our Kentucky communities.
