Insights

Banking sector M&A analyst

BancFirst expands its Oklahoma community banking footprint via acquisition.

BancFirst Corporation has acquired American Bank of Oklahoma, a community bank with approximately $393 million in total assets, $253 million in loans and $328 million in deposits. The acquired institution operates six branches in smaller Oklahoma markets including Collinsville, Disney, Ramona, Skiatook and Muskogee, which adds geographical reach within the state.

The transaction keeps American Bank of Oklahoma operating under its existing name initially, with a merger into BancFirst expected in the first quarter of 2026. This phased approach is common in bank deals, allowing time to integrate systems, customers and staff while maintaining local branding in the near term.

Once the merger occurs in the first quarter of 2026, investors can compare loan and deposit trends in these added markets to assess how effectively BancFirst is incorporating the acquired balance sheet and franchise into its broader network.
