"We are pleased to expand our footprint in Kentucky through the acquisition of an exceptional franchise in Citizens Bank of Kentucky. Their locations are within areas that mean a lot to us," said Tyler Wilcox, President and Chief Executive Officer of Peoples. "Citizens' low-cost deposits and high level of balance sheet liquidity allow us to not only strengthen the Peoples' deposit base but to also maintain the flexibility to remain under $10 billion in assets. We look forward to growing in Eastern Kentucky, working alongside Citizens' employees, customers, and communities. Soon we will be able to offer more locations, products, and services to both Citizens and Peoples customers, making a greater impact in our Eastern Kentucky communities."

Peoples has built a strong reputation in community banking and their experience in successful acquisition integrations will help deliver their relationship and community-driven culture to all of the Citizens stakeholders."

According to the terms of the Merger Agreement, which has been unanimously approved by the Boards of Directors of both companies, shareholders of Citizens will receive 2.10 shares of Peoples common stock plus $8.00 in cash for each share of Citizens' common stock.
