**CEO Commentary**

Stacy Kymes, President and CEO, stated, "Our results this quarter represent a strong capstone to a year of outstanding performance and disciplined execution, highlighted by record earnings per share performance. Loan growth was exceptional this quarter with outstanding loans increasing 3.2% driven by robust growth in our core commercial and industrial lines as well as our specialty businesses. Net interest income has grown every quarter this year and our fee businesses continue to demonstrate the strength of our diversified business model, delivering not only record quarters, but record years for both our Fiduciary and Asset Management and Transaction Card businesses. We are a company well positioned for growth, anchored by a long history of disciplined risk management."

Brokerage and trading revenue increased $4.1 million to $47.3 million. Trading fees and commissions revenue increased $5.4 million. Higher U.S. agency residential mortgage-backed securities trading activity was driven by a more favorable rate environment and an improved future economic outlook, including a steepening yield curve. Investment banking revenue decreased $1.9 million. Municipal underwriting activity resumed a more normal level following a strong third quarter, partially offset by growth in loan syndication fees.

Fiduciary and asset management revenue was up $4.5 million driven by growth in trust fees, primarily from higher transaction-related fees, improved market valuations, and continued growth in client relationships.

Transaction card revenue increased $2.1 million due to an increase in the volume of transactions processed during the period.

Other gains, net, were a net gain of $28.1 million compared to a net gain of $8.3 million in the prior quarter. The fourth quarter included a $23.5 million pre-tax gain on the sale of a merchant banking investment.

Total operating expense was $361.1 million for the fourth quarter of 2025, a decrease of $8.7 million compared to the prior quarter.

Personnel expense was $222.7 million, a decrease of $3.6 million. Employee benefits expense decreased $4.4 million related to lower employee healthcare costs, retirement plan costs, and payroll tax expense. Cash-based incentive compensation increased $3.6 million, primarily driven by strong loan origination activity. Deferred compensation expense was $2.4 million, a decrease of $3.4 million compared to the prior quarter. The impact of deferred compensation expense is offset by the change in the fair value of related investments included in Other gains (losses), net.

Non-personnel expense was $138.3 million, a decrease of $5.1 million. FDIC special assessment expense decreased $8.3 million, primarily due to the FDIC updating their estimate of the special assessment and other adjustments related to the special assessment. Other expense decreased by $1.3 million due to lower operational losses. Professional fees and services increased $3.2 million, primarily driven by additional projects in the quarter. Business promotion expense grew $1.6 million due to higher travel and advertising costs, while data processing and communications costs increased $1.2 million, driven by growth in the volume of transactions processed for our transaction card customers during the quarter.

Outstanding loans were $25.7 billion at December 31, 2025, an increase of $786 million over September 30, 2025, primarily due to growth in commercial loans. Unfunded loan commitments grew by $590 million over the third quarter of 2025.

Outstanding commercial loan balances, which includes healthcare, services, energy, and general business loans, increased $768 million over the prior quarter.

General business loans increased $236 million to $4.5 billion, or 17% of total loans. General business loans include $2.9 billion of wholesale/retail loans and $1.6 billion of loans from other commercial industries.

Services sector loan balances were up $201 million over the prior quarter to $3.9 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.

Energy loan balances grew by $201 million to $2.9 billion, or 11% of total loans, following elevated payoff activity in recent quarters due to industry consolidation. 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 71% of committed production loans are secured by properties primarily producing oil. The remaining 29% are secured by properties primarily producing natural gas. Unfunded energy loan commitments were $4.4 billion at December 31, 2025, a $44 million increase over September 30, 2025.

Healthcare sector loan balances increased $130 million and totaled $4.0 billion, or 16% of total loans. Our healthcare sector loans primarily consist of $3.3 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.

Commercial real estate loan balances decreased $81 million to $5.7 billion, representing 22% of total loans.

Other real estate loans increased by $26 million. Unfunded commercial real estate loan commitments were $2.2 billion at December 31, 2025, a $65 million increase over September 30, 2025. 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 $99 million over the prior quarter to $4.7 billion and represent 18% of total loans. Residential mortgage loans increased $62 million and personal loans increased $37 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.

Our funding sources, which primarily include deposits and wholesale borrowings, provide adequate liquidity to meet our needs. The loan to deposit ratio was 65% at both December 31, 2025 and September 30, 2025, providing significant on-balance sheet liquidity to meet future loan demand and contractual obligations.

Period end deposits totaled $39.4 billion at December 31, 2025, a $935 million increase. Interest-bearing transaction accounts increased $867 million and demand deposits increased $175 million, while time deposits decreased $124 million.

Average Wealth Management deposits decreased by $28 million to $10.7 billion, or 27% of total deposits. Average Funds Management and Other deposits increased $1.2 billion to $2.5 billion. This was primarily driven by opportunistically replacing wholesale borrowings with wholesale deposits.

The company's tangible common equity ratio<sup>1</sup>, a non-GAAP measure, was 9.46% at December 31, 2025, and 10.06% at September 30, 2025. The tangible common equity ratio is primarily based on total shareholders' equity, which includes unrealized gains and losses on available-for-sale securities.

On November 6, 2025, BOKF, NA, the wholly-owned banking subsidiary of BOK Financial Corporation, issued $400 million 6.108% fixed rate reset subordinated notes that will mature on November 6, 2040 and qualify for Tier II regulatory capital treatment.

The company repurchased 2,617,414 shares of common stock at an average price paid of $107.99 per share in the fourth quarter of 2025, and 365,547 shares of common stock at an average price paid of $111.00 per share in the third quarter of 2025. We view buybacks opportunistically, but within the context of maintaining our strong capital position.

**Credit Quality**

Nonperforming assets totaled $75 million, or 0.29% of outstanding loans and repossessed assets, at December 31, 2025, compared to $74 million, or 0.30%, at September 30, 2025.

Nonaccruing loans increased $2.0 million compared to September 30, 2025. New nonaccruing loans identified in the fourth quarter totaled $12.9 million, offset by $6.3 million in payments received, $2.4 million in charge-offs, and $2.1 million in loans that returned to accrual status. Nonaccruing general business loans increased $6.4 million while nonaccruing loans to individuals decreased $1.8 million and nonaccruing services loans decreased $1.5 million.

Net charge-offs were $1.4 million, or 0.02% of average loans on an annualized basis, in the fourth quarter. At December 31, 2025, net charge-offs for the trailing twelve months were $6.7 million, or 0.03% of average loans. Net charge-offs were $3.6 million, or 0.06% of average loans on an annualized basis, in the third quarter of 2025.

No provision for expected credit losses was necessary for the fourth quarter of 2025, primarily due to an improvement in economic forecast assumptions offset by the impact of loan growth during the quarter.

At December 31, 2025, the combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $327 million, or 1.28% of outstanding loans and 497% of nonaccruing loans, excluding residential mortgage loans guaranteed by U.S. government agencies. At September 30, 2025, the combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $328 million, or 1.32% of outstanding loans and 505% of nonaccruing loans.

Combined net interest income and fee revenue increased $5.4 million. Investment banking revenue increased $2.9 million driven by growth in loan syndication fees.

Net loans charged off decreased $1.7 million to $929 thousand in the fourth quarter of 2025. Other operating expenses increased $4.9 million, largely due to higher incentive compensation costs and additional technology projects in the quarter.

 <br> <br> <u>BOK Financial Corporation quarterly earnings release</u> <u>Exhibit 99.1(a)</u>

Consumer Banking contributed $15.1 million to net income before taxes in the fourth quarter of 2025, relatively consistent with the prior quarter. Combined net interest income and fee revenue totaled $94.8 million, a decrease of $1.8 million, primarily due to a decrease in the spread on deposits. The net cost of the change in the fair value of mortgage servicing rights and the related economic hedges was $579 thousand, compared to a cost of $2.1 million in the prior quarter. Other operating expenses were consistent with the prior quarter and corporate expense allocations decreased $1.0 million. Average loans increased $83 million, or 3%, to $2.5 billion. Average deposits were consistent with prior quarter at $8.3 billion.

Wealth Management contributed $42.7 million to net income before taxes in the fourth quarter of 2025, an increase of $6.1 million over the third quarter of 2025. Combined net interest income and fee revenue increased $5.0 million, primarily due to higher fiduciary and asset management fees driven by transaction-related fees combined with increased market valuations and continued growth in client relationships. Trading fees increased $5.4 million, driven by higher U.S agency residential mortgage-backed securities trading activity during the quarter, offset by municipal underwriting revenue returning to more normalized levels following a strong third quarter. Other operating expenses were consistent with the prior quarter. Average loans increased $40 million, or 2%, to $2.4 billion. Average deposits were largely unchanged at $10.7 billion. Assets under management or administration were $126.6 billion, an increase of $3.9 billion, or 3%.

 <br> <u>BOK Financial Corporation Quarterly Earnings Release</u> <u>Exhibit 99.1(b)</u>

**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 does 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.
