Is BANF a Buy? What to Consider in 2026
Short answer
The bull case for BancFirst Corporation (BANF) rests on Net interest income growth: Net interest income rose to about $127.6 million in Q1 2026 from roughly $115.9 million a year earlier, driven by higher loan volume and growth in earning assets. Diluted EPS (FY2025) is ~$7.11. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: As a regional bank, BancFirst is exposed to interest-rate swings that can compress its net interest margin, and to credit deterioration if Oklahoma and Texas borrowers weaken. Whether BANF is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
BancFirst Corporation is a financial holding company headquartered in Oklahoma City that operates mainly through its principal subsidiary bank, BancFirst, plus Texas-chartered Pegasus Bank and Worthington Bank and a BancFirst Insurance Services agency. It runs a super-community model, blending the local decision-making of small-town branches with the product breadth of a larger institution, and as of March 31, 2026 it held roughly $15.1 billion in total assets, about $8.6 billion in loans, and about $12.9 billion in deposits. Its earnings come primarily from net interest income (the spread between what it earns on loans and pays on deposits) supplemented by fee-based noninterest income. The investment picture is that of a well-capitalized, low-cost-deposit regional bank that compounds through both organic loan growth and a long history of acquiring smaller Oklahoma and Texas banks (American Bank of Oklahoma in 2025 and the roughly $939.6 million-asset SpiritBank announced in 2026). BancFirst reported record net income and earnings per share for the fifth consecutive year in 2025, and it was ranked in the top 50 of Forbes' America's Best Banks of 2026. As with any bank, results are tied to interest rates, credit quality, and the health of its concentrated Oklahoma and Texas markets.
What's the case for buying BANF?
1. Net interest income growth
Net interest income rose to about $127.6 million in Q1 2026 from roughly $115.9 million a year earlier, driven by higher loan volume and growth in earning assets. Net interest margin expanded modestly to about 3.74%. A large base of low-cost core deposits is the structural advantage that funds this spread.
2. Acquisition-led expansion
BancFirst has a long track record of buying smaller community banks in its footprint, including American Bank of Oklahoma in 2025 and the roughly $939.6 million-asset SpiritBank announced in 2026. These bolt-on deals add deposits, branches, and lending relationships while the company retains its decentralized operating model.
3. Concentrated regional franchise
Deep density in Oklahoma, plus a growing Texas presence through Pegasus Bank and Worthington Bank, gives BancFirst local scale and brand recognition. Being the highest-rated Oklahoma bank on Forbes' 2026 list reflects a franchise built on relationship banking rather than rate competition.
4. Diversified fee income
Noninterest income of about $51.4 million in Q1 2026 (from insurance, treasury services, and card/transaction fees) supplements spread income. This mix smooths earnings somewhat when interest rates or loan demand shift.
What are the risks to BANF?
As a regional bank, BancFirst is exposed to interest-rate swings that can compress its net interest margin, and to credit deterioration if Oklahoma and Texas borrowers weaken. Its geographic concentration ties results closely to those two state economies, including energy, agriculture, and commercial real estate exposure. Acquisitions carry integration and overpayment risk, and deposit competition can raise funding costs. Broader banking-sector stress, regulation, and deposit-flight events (as seen across regional banks in recent years) are industry-wide risks it cannot fully control.

How do you decide if BANF is a buy?
Rather than asking whether BANF is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold BANF indirectly through an index or sector ETF before adding more.
