BancFirst Corporation, an Oklahoma-based financial services holding company listed on Nasdaq, has signed a deal to acquire American Bank of Oklahoma for an undisclosed price.

Based in Collinsville, Oklahoma, American Bank of Oklahoma operates as a community bank.

BancFirst CEO David Harlow said: “Collinsville and Skiatook are thriving communities that continue to experience dynamic growth in Northeastern Oklahoma.

“We are excited to welcome the American Bank of Oklahoma team and their customers to BancFirst. This acquisition aligns with our continued commitment to serving communities here in our home state.”

American Bank of Oklahoma currently manages assets valued at approximately $385m, loans totalling $280m, and deposits amounting to $320m.

It will continue to operate under its existing name until the merger with BancFirst occurs, which is anticipated in Q4 2025.

American Bank of Oklahoma president and CEO Teresa Brown said: “Joining forces with BancFirst represents a great opportunity for our customers and employees to join one of the strongest banks in the country. We share common values and a commitment to local service, and we look forward to the partnership.”

The closing of the deal is expected to take place in Q3 2025, pending regulatory approvals and standard closing conditions.

BancFirst, which is headquartered in Oklahoma City, manages total assets amounting to $14bn as of 31 March 2025.

Operating through its primary subsidiary, BancFirst, the company also wholly owns BancFirst Insurance Services.

In April 2025, BancFirst reported its earnings for the first quarter of the year (Q1 2025). The company achieved a net income of $56.1m or $1.67 per diluted share, surpassing its previous year’s first-quarter net income of $50.3m or $1.5 per diluted share.

The increase in net interest income to $115.9m from $106.1m in 2024 was driven by higher loan volume and overall growth in earning assets. Despite these changes, the net interest margin remained steady at 3.7% compared to the prior year.

A provision for credit losses was recorded at $1.6m for Q1 2025, down from $4m in the previous year. By 31 March 2025, its total assets had increased by $483.7m since 31 December 2024.

Loans grew by $69.6m during this period, totalling $8.1bn by the end of March 2025. Deposits had also increased by $408.2m from year-end 2024, reaching a total of $12.1bn.
