Filing Explained

The filing adds a completed 2,519-share buyback and separates 16.6 billion dollars of unfunded commitments from 27.1 billion dollars of outstanding loans.

On July 20, 2026, BOK Financial filed a Form 8-K reporting completed financial results for the three and six months ended June 30, 2026, rather than a proposed or pending operating event.

The filing records a completed second-quarter repurchase of $327 thousand covering 2,519 common shares at an average price of $129.89 per share; this is a buyback, not an issuance of new shares.

It separately reports $27.1 billion of period-end outstanding loans and $16.6 billion of unfunded loan commitments, with the latter not presented as funded lending.

Form 8-K filings report specified material events within four business days; here, Items 2.02 and 7.01 cover results and Regulation FD disclosure, while Item 9.01 lists the exhibits. The filing also schedules a conference call for July 21, 2026, the next stated venue for discussing these results.

Net interest income (Q2 2026) $351.8 million Quarter ended June 30, 2026
Net interest margin (Q2 2026) 2.91% Quarterly consolidated net interest margin
Period-end loans $27.1 billion Outstanding loans at June 30, 2026
Period-end deposits $39.9 billion Total deposits at June 30, 2026
Common equity Tier 1 capital ratio 12.89% Regulatory CET1 ratio at June 30, 2026
net interest margin financial
"Net interest margin was 2.91% for the second quarter compared to 2.90%."
Net interest margin measures how much a bank earns from lending and investing compared with what it pays for funding, expressed as a percentage of its interest-earning assets. Think of it like a grocery store’s markup: it shows the gap between buying cost and selling price per dollar of goods — here, the cost is interest paid and the sale is interest received. Investors watch it because a higher margin usually means a bank is more profitable and better at managing interest rate and credit conditions.
tangible common equity ratio financial
"Tangible common equity ratio was 9.61% compared to 9.29% at March 31, 2026."
Tangible common equity ratio measures how much real, loss-absorbing capital common shareholders have relative to a company's tangible assets—calculated by removing intangible items (like goodwill) and preferred equity from total equity and comparing that net amount to tangible assets. Think of it as the thickness of a safety cushion made of solid, visible value rather than accounting entries; investors use it to judge how well a company could withstand losses and protect common shareholders' claims.
available-for-sale securities financial
"Losses on available-for-sale securities, net, were $4.6 million in the second quarter of 2026."
Available-for-sale securities are investments in stocks, bonds or similar instruments that a company does not intend to trade frequently but may sell before they mature. They matter to investors because changes in the market value of these holdings show up as paper gains or losses on the company's balance sheet rather than immediately in profit, so they can affect reported net worth and the timing of income without changing day-to-day earnings. Think of them like items on a household shelf you might sell later: their value moves with the market even if you haven’t cashed out.
nonperforming assets financial
"Nonperforming assets were $63 million, or 0.23% of outstanding loans and repossessed assets."
Nonperforming assets are loans or investments that are not generating expected payments or returns because the borrower has fallen behind on payments or the investment has lost value. They matter to investors because a high level of nonperforming assets can indicate financial trouble for a bank or institution, potentially affecting its stability and profitability.
pre-provision net revenue financial
"Pre-provision net revenue was $227,680 thousand in the quarter ended June 30, 2026."
Pre-provision net revenue is a bank’s income from core operations — interest earned minus interest paid plus fees and other operating income, after operating costs — measured before setting aside funds for potential loan losses. Investors use it to gauge how well a bank’s everyday business generates money independent of one-time loss reserves, like judging a store’s sales and operating profit before accounting for an expected number of returned items.
Net income attributable to shareholders (Q2 2026) $176.5 million Compared to $155.8 million in Q1 2026 and $140.0 million in Q2 2025
Diluted EPS (Q2 2026) $2.92 per share Compared to $2.58 in Q1 2026 and $2.19 in Q2 2025
Net interest income (Q2 2026) $351.8 million Up from $342.6 million in Q1 2026
Total other operating revenue (Q2 2026) $237.6 million Up from $211.3 million in Q1 2026 and $207.1 million in Q2 2025

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.

Outstanding loans were $27.1 billion at June 30, 2026, an increase of $896 million over March 31, 2026, driven by broad-based growth across our loan portfolio. Unfunded loan commitments grew by $443 million over the first quarter of 2026 to $16.6 billion at June 30, 2026.
Outstanding commercial loan balances, which includes services, healthcare, energy, mortgage finance, and general business loans, increased $724 million over the prior quarter.
The Company launched the residential mortgage finance line of business in the third quarter of 2025, and these loan balances increased by $224 million during the current quarter to $452 million, or 2% of total loans.
Services sector loan balances were up $198 million over the prior quarter at $4.1 billion, or 15% of total loans. Services 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.
Healthcare sector loan balances increased $128 million and totaled $4.1 billion, or 15% of total loans. Our healthcare sector loans primarily consist of $3.2 billion 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.
General business loans increased $128 million to $4.6 billion, or 17% of total loans. General business loans include $2.9 billion of wholesale/retail loans and $1.7 billion of loans from other commercial industries.

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.
Commercial real estate loan balances were largely unchanged compared to prior quarter at $5.9 billion, representing 22% of total loans. Loans secured by industrial facilities decreased $135 million. Loans secured by retail facilities increased $57 million, loans secured by office facilities increased $31 million, other real estate loans increased $29 million, and loans secured by multifamily properties increased $17 million. Unfunded commercial real estate loan commitments were $2.2 billion at June 30, 2026, a $105 million increase compared to March 31, 2026. We take a disciplined approach to managing our concentration of commercial real estate loan commitments as a percentage of capital.
Loans to individuals were up $171 million over the prior quarter to $4.9 billion and represent 18% of total loans. Personal loans increased $108 million and residential mortgage loans increased $63 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 12.89% at June 30, 2026. 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. Nonaccruing general business loans increased $2.3 million and nonaccruing services loans increased $1.7 million, while nonaccruing loans to individuals decreased $1.6 million.
Net charge-offs were $500 thousand, or 0.01% of average loans on an annualized basis, in the second quarter. 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. At March 31, 2026, the combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $323 million, or 1.23% of outstanding loans and 618% of nonaccruing loans.

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.

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.

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%.

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.
