Net income was $176.5 million, or $2.92 per diluted share, compared to $155.8 million, or $2.58 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, net income would have been $156.5 million, or $2.59 per diluted share, in the second quarter of 2026.2

CEO Commentary
Stacy Kymes, President and CEO, stated, “I am proud of the strong results our team delivered this quarter, highlighted by the highest quarterly loan production in the Company’s history. Loans increased nearly $900 million during the quarter and are up 11.5% from a year ago, driven by diverse growth across business lines and geographies. Core net interest income increased, margins remained stable, and our fee generating businesses continue to provide meaningful support. In fact, our Fiduciary and Asset Management business posted record revenue this quarter. Our consistent performance is rooted in a strong risk management culture, and our unique geographic footprint continues to create opportunities to grow faster than peers while maintaining our disciplined approach."

Net interest income was $351.8 million for the second quarter of 2026, an increase of $9.3 million over the prior quarter. Net interest margin expanded to 2.91% from 2.90%. For the second quarter of 2026, our core net interest margin excluding trading activities1, a non-GAAP measure, decreased 2 basis points to 3.13% compared to 3.15% in the prior quarter. Net interest margin benefited from favorable repricing of fixed-rate assets and deposits. During the quarter, these positive drivers were partially offset by a 3 basis point impact from cash margin posted on behalf of our energy customers as oil prices increased during the quarter.

Energy loan balances grew by $47 million to $3.1 billion, or 11% 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. Unfunded energy loan commitments were $4.6 billion at June 30, 2026, a $117 million increase over March 31, 2026.

Personal loans increased $108 million and residential mortgage loans increased $63 million.

In addition, the company's Tier 1 capital ratio was 12.90%, total capital ratio was 14.67%, and leverage ratio was 9.81% at June 30, 2026.

The company's tangible common equity ratio1, a non-GAAP measure, was 9.61% at June 30, 2026, and 9.29% at March 31, 2026. The tangible common equity ratio is primarily based on total shareholders' equity, which includes unrealized gains and losses on available-for-sale securities.
The company repurchased 2,519 shares of common stock at an average price paid of 129.89 per share in the second quarter of 2026. No shares of common stock were repurchased in the first quarter of 2026. We view buybacks opportunistically, but within the context of maintaining our strong capital position.

Credit Quality
Nonperforming assets totaled $63 million, or 0.23% of outstanding loans and repossessed assets, at June 30, 2026, compared to $60 million, or 0.23%, at March 31, 2026. Excluding loans guaranteed by U.S. government agencies, nonperforming assets totaled $55 million, or 0.20% of outstanding loans and repossessed assets, at June 30, 2026, compared to $52 million, or 0.20%, at March 31, 2026.
Nonaccruing loans increased $2.1 million compared to March 31, 2026. New nonaccruing loans identified in the second quarter totaled $8.5 million, offset by $3.4 million in payments received and $1.3 million in charge-offs.

At June 30, 2026, net charge-offs for the trailing twelve months were $7.4 million, or 0.03% of average loans. Net charge-offs were $1.9 million, or 0.03% of average loans on an annualized basis, in the first quarter of 2026.
No provision for expected credit losses was necessary for the second quarter of 2026. An improvement in economic forecast assumptions, including GDP growth, lower unemployment, and improved vacancy rates, compared to the prior quarter, was offset by the impact of loan growth during the quarter.
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.

Commercial Banking contributed $146.2 million to net income before taxes in the second quarter of 2026, an increase of $11.4 million over the first quarter of 2026. Combined net interest income and fee revenue totaled $240.4 million, an increase of $7.9 million. Net interest income increased $5.5 million due to increased loan volumes and beneficial repricing of deposits. Investment banking revenue increased $3.9 million, primarily due to higher loan syndication fees and was partially offset by a $1.4 million decrease in customer hedging revenue. Other operating expenses were consistent with the prior quarter. Other gains, net, were $4.3 million for the second quarter of 2026, compared to $1.2 million in the first quarter of 2026 from merchant banking activities. Average loans increased $770 million, or 4%, to $22.0 billion. Average deposits were $18.9 billion, an increase of $612 million, or 3%.

Consumer Banking contributed $13.6 million to net income before taxes in the second quarter of 2026, a decrease of $5.6 million. Combined net interest income and fee revenue decreased $1.2 million, driven by a decrease in mortgage production performance and lower card-network incentives, partially offset by changes in deposit spreads. The net cost of the change in the fair value of mortgage servicing rights and the related economic hedges was $914 thousand, compared to a net benefit of $2.0 million in the prior quarter. Other operating expenses were consistent with the prior quarter. Corporate expense allocations increased $1.9 million. Average loans increased $50 million, or 2%, to $2.6 billion. Average deposits increased $204 million, or 2%, to $8.6 billion.
Wealth Management contributed $35.0 million to net income before taxes in the second quarter of 2026, a decrease of $2.6 million compared to the first quarter of 2026. Combined net interest income and fee revenue decreased $6.9 million, largely due to reduced trading activity from interest rate market volatility during the quarter, partially offset by a $4.5 million increase in fiduciary and asset management revenue from seasonal tax preparation fee income combined with higher trust business line fees. Other operating expenses decreased $4.0 million, primarily due to lower cash-based incentive compensation costs driven by the decrease in trading activity. Average loans increased $48 million, or 2%, to $2.5 billion. Average deposits were largely unchanged at $10.7 billion. Assets under management or administration were $129.3 billion, an increase of $5.7 billion, or 5%.

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.

Yield calculations are shown on a tax-equivalent basis at the statutory federal and state rates for the periods presented. The yield calculations exclude security trades that have been recorded on trade date with no corresponding interest income and the unrealized gains and losses. The yield calculation also includes average loan balances for which the accrual of interest has been discontinued and are net of unearned income. Yield/rate calculations are generally based on the conventions that determine how interest income and expense is accrued.
