BOK Financial Corporation reports quarterly earnings of $160 million, or $2.64 per share, in the third quarter.
Third quarter 2026 financial highlights1
Net Income
Net income was $159.9 million, or $2.64 per diluted share, compared to $176.5 million, or $2.92 per diluted share. Prior quarter net income would have been $156.5 million, or $2.59 per diluted share, excluding the net gain related to the exchange of Visa B shares and the loss from repositioning of the available-for-sale securities portfolio.2
Net Interest Income & Margin
Net interest income totaled $370.0 million, an increase of $18.1 million. Net interest margin was 3.00% for the third quarter compared to 2.91% in the prior quarter.
Fees & Commissions Revenue
Fees and commissions revenue was $188.0 million compared to $202.0 million in the prior quarter. Brokerage and trading revenue decreased $13.0 million due to an unfavorable rate environment and lower fixed-income trading volumes.
Operating Expense
Operating expense was largely consistent with the prior quarter at $360.7 million, as both personnel and non-personnel expense remained stable compared to the second quarter of 2026.
Loans
Period end loans were up $646 million over the prior quarter, to $27.7 billion, led by growth in energy loans, loans secured by industrial facilities, and mortgage finance loans. Average outstanding loan balances were $27.2 billion, an increase of $468 million.
Credit Quality
Nonperforming assets were $67 million, or 0.24% of outstanding loans and repossessed assets, at September 30, 2026, compared to $63 million, or 0.23%, at June 30, 2026. Net charge-offs for the third quarter were $886 thousand, or 0.01% of average loans on an annualized basis.
Deposits
Period end deposits decreased $324 million to $39.5 billion, and average deposits increased $304 million to $39.5 billion. Average interest-bearing deposits increased $278 million and average demand deposits increased by $26 million. The loan to deposit ratio was 70% at September 30, 2026, compared to 68% at June 30, 2026.

CEO Commentary
Stacy Kymes, President and CEO, stated, “We delivered another strong quarter, with $646 million of loan growth, 11.5% year-over-year loan growth, continued expansion in core net interest income, and peer-leading credit outcomes. Our disciplined approach to managing the balance sheet also helped us exit the quarter with top-quartile tangible common equity, despite a period of rapidly increasing interest rates.
These results are intentional, not accidental. They reflect decisions we have made consistently over many years around capital, liquidity, interest rate risk and credit. Higher rates created headwinds for mortgage banking and fixed-income trading this quarter, but we view those businesses through the cycle, where they provide an important source of diversification to our overall earnings profile.
We manage the company for the long term, not for any one quarter. That discipline, combined with the diversity of our franchise, positions us to deliver durable performance and continue serving our customers well across a wide range of operating environments."
1 Comparisons are to the prior quarter unless otherwise noted.

Net interest income was $370.0 million for the third quarter of 2026, an increase of $18.1 million over the prior quarter. Net interest margin expanded to 3.00% from 2.91%. For the third quarter of 2026, our core net interest margin excluding trading activities1, a non-GAAP measure, increased 8 basis points to 3.21% compared to 3.13% in the prior quarter.

Total other operating revenue $ 191,471 $ 237,572 $ (46,101) (19.4) %
Fees and commissions revenue totaled $188.0 million for the third quarter of 2026, decreasing $14.0 million compared to the prior quarter.
Brokerage and trading revenue decreased $13.0 million to $19.5 million, primarily driven by an unfavorable rate environment and lower fixed-income trading volumes during the quarter. The nearly 80 basis point increase in the 10-year Treasury yield reduced customer demand for fixed-income products and mortgage-related activity, resulting in lower transaction volumes and trading revenues.
Mortgage banking revenue decreased $2.2 million, driven by a decline in mortgage production volume and spreads due to rising mortgage interest rates. Production revenue as a percentage of production volume decreased 77 basis points to 0.06%.
Fiduciary and asset management revenue decreased $1.1 million, as the prior quarter benefited from seasonal tax preparation fees. Excluding this seasonal revenue, fiduciary and asset management revenue increased over the prior quarter.
Other gains, net, were a net gain of $5.7 million compared to a net gain of $42.4 million in the prior quarter. The second quarter of 2026 included a $30.9 million pre-tax gain, net of economic hedge, related to the exchange of our Visa B shares under the exchange offer by Visa, Inc. The current quarter included a net gain on investments related to deferred compensation of $1.8 million compared to a net gain of $8.8 million in the prior quarter.

Total operating expense remained stable at $360.7 million for the third quarter of 2026.

Excluding the impact of deferred compensation, total operating expense increased $6.4 million.
Personnel costs increased $6.5 million excluding the impact of deferred compensation. Regular compensation expense increased $3.2 million, primarily reflecting investments in talent, including the addition of revenue-producing personnel. Cash-based incentive compensation increased $1.2 million due to strong loan production during the quarter. Employee benefits expense increased $1.1 million, driven by higher employee healthcare costs, partially offset by a seasonal decrease in payroll taxes.
Non-personnel expense was consistent with the prior quarter. A $2.6 million increase in data processing and communications expense, primarily driven by higher software costs, was fully offset by decreases in business promotion expense and net occupancy and equipment costs. Mortgage banking costs decreased $1.2 million due to lower loan payoff activity during the quarter.

Outstanding commercial loan balances, which include services, healthcare, energy, mortgage finance, and general business loans, increased $358 million over the prior quarter.
Energy loan balances grew by $264 million to $3.3 billion, or 12% of total loans. The majority of this portfolio is first lien, senior secured, reserve-based lending to oil and gas producers, which we believe is the lowest risk form of energy lending. Approximately 72% of committed production loans are secured by properties primarily producing oil. The remaining 28% are secured by properties primarily producing natural gas.

The Company launched the residential mortgage finance line of business in the third quarter of 2025, and these loan balances increased by $137 million during the current quarter to $589 million, or 2% of total loans. Mortgage finance loans primarily consist of warehouse lending facilities to Independent Mortgage Bankers to fund residential mortgages.

Services sector loan balances decreased $29 million compared to the prior quarter and totaled $4.1 billion, or 15% of total loans. Services sector loans consist of a large number of loans to a variety of businesses, including state and local municipal government entities, Native American tribal government and casino operations, foundations and not-for-profit organizations, educational services, and specialty trade contractors.

BOK Financial Corporation quarterly earnings release Exhibit 99.1(a)
Healthcare sector loan balances decreased $59 million and totaled $4.0 billion, or 15% of total loans. Our healthcare sector loans primarily consist of $3.1 billion of loans for the development and operation of senior housing and care facilities, including independent living, assisted living, and skilled nursing. Generally, we loan to borrowers with a portfolio of multiple facilities, which serves to help diversify risks specific to a single facility.
Commercial real estate loan balances increased $248 million to $6.1 billion, representing 22% of total loans. Loans secured by industrial facilities increased $166 million, other real estate loans increased $78 million, and loans secured by retail facilities increased $36 million. Loans secured by multifamily residential properties decreased $20 million and loans secured by office facilities decreased $12 million to $841 million. Unfunded commercial real estate loan commitments were $2.4 billion at September 30, 2026, a $105 million increase over June 30, 2026. We take a disciplined approach to managing our concentration of commercial real estate loan commitments as a percentage of capital.
Loans to individuals increased $40 million to $4.9 billion and represented 18% of total loans. Personal loans increased by $26 million and residential mortgage loans increased $14 million. Personal loans consist primarily of loans to Wealth Management clients secured by the cash surrender value of insurance policies or marketable securities. Personal loans also include direct loans secured by and for the purchase of automobiles, recreational and marine equipment, as well as unsecured loans.

The company's common equity Tier 1 capital ratio was 12.73% at September 30, 2026. In addition, the company's Tier 1 capital ratio was 12.73%, total capital ratio was 14.43%, and leverage ratio was 9.95% at September 30, 2026.

The company's tangible common equity ratio1, a non-GAAP measure, was 9.16% at September 30, 2026, and 9.61% at June 30, 2026. The tangible common equity ratio is primarily based on total shareholders' equity, which includes unrealized gains and losses on available-for-sale securities.
No shares of common stock were repurchased during the third quarter of 2026. The company repurchased 2,519 shares of common stock at an average price of $129.89 per share in the second quarter of 2026. We view buybacks opportunistically, but within the context of maintaining our strong capital position.
Credit Quality
Nonperforming assets totaled $67 million, or 0.24% of outstanding loans and repossessed assets, at September 30, 2026, compared to $63 million, or 0.23%, at June 30, 2026. Excluding loans guaranteed by U.S. government agencies, nonperforming assets totaled $58 million, or 0.21% of outstanding loans and repossessed assets, at September 30, 2026, compared to $55 million, or 0.20%, at June 30, 2026.
Nonaccruing loans increased $4.1 million compared to June 30, 2026. New nonaccruing loans identified in the third quarter totaled $12 million, offset by $4.7 million in payments received, $1.7 million in charge-offs, and $1.2 million in loans that returned to accrual status. Nonaccruing healthcare loans increased $4.0 million and nonaccruing loans to individuals increased $1.6 million, while nonaccruing general business loans decreased $1.3 million.
Net charge-offs were $886 thousand, or 0.01% of average loans on an annualized basis, in the third quarter. At September 30, 2026, net charge-offs for the trailing twelve months were $4.7 million, or 0.02% of average loans. Net charge-offs were $500 thousand, or 0.01% of average loans on an annualized basis, in the second quarter of 2026.
No provision for expected credit losses was necessary for the third quarter of 2026. An improvement in economic forecast assumptions, primarily GDP growth and lower unemployment, compared to the prior quarter was offset by the impact of loan growth during the quarter.
At September 30, 2026, the combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $322 million, or 1.16% of outstanding loans and 555% of nonaccruing loans, excluding residential mortgage loans guaranteed by U.S. government agencies. At June 30, 2026, the combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $323 million, or 1.19% of outstanding loans and 592% of nonaccruing loans, excluding residential mortgage loans guaranteed by U.S. government agencies.

BOK Financial Corporation Quarterly Earnings Release
Exhibit 99.1(b)
Explanation of Non-GAAP Measures
The tangible common equity ratio and return on average tangible common equity are primarily based on total shareholders' equity, which includes unrealized gains and losses on available-for-sale securities, less intangible assets and equity that do not benefit common shareholders. These measures are valuable indicators of a financial institution's capital strength since they eliminate intangible assets from shareholders' equity and retain the effect of unrealized losses on securities and other components of accumulated other comprehensive income in shareholders' equity.
The efficiency ratio and adjusted efficiency ratio measure the company's ability to use its assets and manage its liabilities effectively in the current period.
Pre-provision net revenue is a measure of revenue less expenses and is calculated before provision for credit losses and income tax expense. This financial measure is frequently used by investors and analysts and enables them to assess a company's ability to generate earnings to cover credit losses through a credit cycle. It also provides an additional basis for comparing the results of operations between periods by isolating the impact of the provision for credit losses, which can vary significantly between periods.
Net interest income and net interest margin excluding trading activities removes the effect of trading activities on these metrics allowing management and investors to assess the performance of the company's core lending and deposit activities without the associated volatility from trading activities.
We believe adjusting net income and earnings per share for notable non-core items enhances comparability of results with prior periods, demonstrates the impact of significant items, and provides a useful measure for determining the company's expenses that are core to our business operations and are expected to recur over time.

All statements other than statements of historical fact are forward-looking statements. Therefore, actual results and outcomes may materially differ from what is expected, implied, or forecasted in such forward-looking statements. Internal and external factors that might cause such a difference include, but are not limited to changes in government, changes in governmental economic policy, including tariffs; changes in commodity prices; interest rates and interest rate relationships; inflation; demand for products and services; the degree of competition by traditional and nontraditional competitors; changes in banking regulations; tax laws; prices, levies and assessments; the impact of technological advances; trends in customer behavior as well as their ability to repay loans; credit quality deterioration; cybersecurity incidents and data breaches; operational failures or interruptions; liquidity risks; capital adequacy requirements; litigation and regulatory enforcement actions; and other risks detailed in BOK Financial Corporation's filings with the Securities and Exchange Commission. For a discussion of risk factors that may cause actual results to differ from expectations, please refer to BOK Financial Corporation’s most recent annual and quarterly reports.
