WesBanco, Inc., a diversified multi-state bank holding company, has successfully completed the merger with Premier Financial Corp., marking the largest conversion in the bank's history. Announced on July 26, 2024, and finalized on February 28, 2025, the merger forms a regional financial services institution with over $27 billion in assets. This expansion elevates WesBanco among the top 100 largest insured depository organizations in the United States and the 8th largest bank in Ohio by deposit market share. The integration involved transitioning approximately 400,000 consumer and 50,000 business relationships, along with rebranding and operational changes in about 70 financial centers across several states. As a result, WesBanco now boasts more than 250 financial centers and loan production offices across nine states. Customer appreciation events are scheduled throughout June to celebrate the transition.
