BANF vs BOKF: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. BANF and BOKF share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined BANF and BOKF exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

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.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• BANF drivers: Net interest income growth; Acquisition-led expansion.
• BOKF drivers: Broad-based loan growth; Diversified fee income.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: 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. For BOKF, as a regional bank, BOKF is exposed to interest-rate swings that can compress net interest margin, which was near 2.90% in early 2026.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick BANF if you believe its drivers more; BOKF if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the BANF and BOKF guides.

BANF. BancFirst reported record full-year net income of roughly $240.6 million (about $7.11 diluted EPS) in 2025, its fifth straight record year, and carried the momentum into a roughly $63.0 million first quarter of 2026. At around $114 per share and a P/E near 15.7, the stock trades in line with a steady, profitable regional bank rather than a high-growth name. The quarterly dividend was $0.49 per share, for a yield near 1.7%.

BOKF. In the first quarter of 2026 BOKF earned about $155.8 million, or $2.58 per diluted share, up meaningfully from $1.86 a year earlier, on revenue of roughly $554 million. The stock traded around a mid-teens price-to-earnings ratio, typical for a well-capitalized regional bank, with a dividend near $0.63 per quarter. Net interest income of about $345 million and net interest margin near 2.90% anchored results alongside strong fee income.

Headline figures (approximate, JULY 2026): BANF shows net interest income (fy2025) ~$490.5M, net income (fy2025) ~$240.6M, diluted eps (fy2025) ~$7.11, net income (q1 2026) ~$63.0M; BOKF shows revenue (q1 2026) ~$554M, net income (q1 2026) ~$156M, diluted eps (q1 2026) ~$2.58, total assets ~$53.8B.

BANF and BOKF are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined BANF and BOKF exposure against your real portfolio. It is not an investment adviser.
