BancFirst Corporation holds a super community bank position in Oklahoma combining local responsiveness with greater lending capacity and broader product lines than typical independent community banks. Its deposit market share in Oklahoma was 7.58% as of June 30, 2025, up from 6.84% as of June 30, 2024, reflecting a competitive standing among state banks. In the North Texas markets where Pegasus and Worthington operate, the company faces intense competition from large national banks, regional institutions, and numerous credit unions, relying on relationship driven growth. Competitive advantages include a decentralized management approach that empowers local presidents, a strong core deposit funding base, centralized operational functions that improve efficiency, and a diversified product suite spanning banking, trust, insurance, and investment services.

The company serves retail customers, small to medium sized businesses, large corporations, financial institutions, and governmental entities. Specific customer names are not disclosed in the filing.
