Net interest income was $308.1 million for the third quarter of 2024, compared to $296.0 million for the prior quarter. Net interest margin was 2.68%, compared to 2.56%, due to increased yields on our available for sale securities portfolio, combined with higher loan fees driven by payoffs and the funding shift from wholesale borrowings to interest-bearing deposits. For the third quarter of 2024, our core net interest margin excluding trading activities, a non-GAAP measure, was 3.02% compared to 2.94% in the prior quarter.

Average earning assets decreased $108 million. Average loan balances decreased $80 million, largely due to a decrease in commercial loans, partially offset by growth in commercial real estate loan balances. Average available for sale securities grew $184 million, while average trading securities decreased $120 million. Average interest-bearing deposits increased $1.2 billion, primarily from interest-bearing transaction accounts. Funds purchased and repurchase agreements decreased $822 million, while average other borrowings decreased $785 million.

The yield on average earning assets was 5.89%, up 9 basis points. The loan portfolio yield increased 6 basis points to 7.47%, while the yield on the available for sale securities portfolio increased 5 basis points to 3.76%. The yield on trading securities was up 30 basis points to 5.36% and the yield on interest-bearing cash and cash equivalents decreased 53 basis points to 5.33%.

Funding costs were 4.11%, down 4 basis points. The cost of interest-bearing deposits increased 3 basis points to 3.79%. The cost of funds purchased and repurchase agreements decreased 39 basis points to 3.89%. The benefit to net interest margin from assets funded by non-interest liabilities was 90 basis points, a decrease of 1 basis point.

Fees and commissions revenue totaled $202.5 million for the third quarter of 2024, an increase of $2.5 million over the prior quarter.

Other revenue increased $3.4 million to $17.4 million, largely due to an increase in letter of credit fees and fees earned on derivative counterparty margin.

Transaction card revenue grew $1.2 million to $28.5 million, primarily due to an increase in the volume of transactions processed during the third quarter of 2024.

Brokerage and trading revenue decreased $2.6 million to $50.4 million. Trading revenue decreased $4.1 million to $23.6 million. A decline in U.S agency residential mortgage-backed securities trading volumes, driven by market conditions in the third quarter of 2024, was partially offset by an increase in municipal trading revenue led by strong activity in this sector. Investment banking revenue and customer hedging revenue also grew slightly over the prior quarter.

Other gains, net, were $13.1 million for the third quarter of 2024, compared to $57.4 million in the second quarter of 2024. The prior quarter included a $53.8 million pre-tax gain on the conversion of our Visa B shares under the exchange offer announced by Visa, Inc. During the third quarter of 2024, we sold the remaining 133,472 converted shares of Visa common stock and realized an additional pre-tax gain of $3.1 million. The current quarter also included a gain on merchant banking investments of $5.0 million and a gain on investments related to deferred compensation of $3.8 million.

Total operating expense was $341.0 million for the third quarter of 2024, an increase of $4.3 million compared to the second quarter of 2024.

Personnel expense was $206.8 million, an increase of $15.7 million. Cash-based incentive compensation expense increased $7.8 million as the prior quarter received a benefit due to a shift in the timing of expense recognition as commercial incentive compensation plans moved to being primarily share-based rather than cash-based awards. Share-based compensation increased $3.5 million based on changes in assumptions of certain performance-based equity awards. Deferred compensation expense increased $1.8 million to $4.0 million; however, this was largely offset by an increase in the value of related investments included in Other gains, net. Regular compensation expense increased $2.7 million, driven by additional staffing and a reduction in the amount of compensation expense capitalized during the third quarter. This was due to decreased loan production levels and the implementation of a significant project in the prior quarter.

Non-personnel expense was $134.2 million, a decrease of $11.4 million. The prior quarter included a $13.6 million charitable donation to the BOKF Foundation. In the third quarter of 2024, the FDIC updated their estimate of the special assessment, resulting in a benefit of $1.4 million, compared to $1.2 million of expense in the prior quarter. Net occupancy and equipment expense increased $1.8 million and data processing and communications expense grew $1.4 million, primarily due to ongoing projects.

Outstanding loans were $24.0 billion at September 30, 2024, a decrease of $569 million compared to June 30, 2024, largely due to a reduction in commercial loans, partially offset by an increase in commercial real estate loans and loans to individuals. Unfunded loan commitments increased $441 million compared to the second quarter of 2024.

Outstanding commercial loan balances, which includes healthcare, services, energy and general business loans, decreased $745 million compared to the prior quarter.

General business loans decreased $335 million to $4.0 billion, or 17% of total loans. General business loans include $2.6 billion of wholesale/retail loans and $1.5 billion of loans from other commercial industries.

Energy loan balances decreased $325 million to $3.1 billion, or 13% 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 70% of committed production loans are secured by properties primarily producing oil. The remaining 30% is secured by properties primarily producing natural gas. Unfunded energy loan commitments were $4.5 billion at September 30, 2024, a $95 million increase over June 30, 2024.

Healthcare sector loan balances decreased $82 million, totaling $4.1 billion, or 17% of total loans. Our healthcare sector loans primarily consist of $3.4 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.

Services sector loan balances were unchanged at $3.6 billion, or 15% of total loans. Services loans consist of a large number of loans to a variety of businesses, including Native American tribal and state and local municipal government entities, Native American tribal casino operations, foundations and not-for-profit organizations, educational services and specialty trade contractors.

Commercial real estate loan balances increased $105 million to $5.2 billion and represent 22% of total loans. Loans secured by multifamily properties increased $112 million to $2.1 billion. Loans secured by industrial facilities increased $56 million to $1.3 billion, and construction and land development loans increased $17 million to $105 million. The increases in these portfolios were partially offset by a $61 million decrease in loans secured by office facilities and a $26 million decrease in loans secured by retail facilities. Unfunded commercial real estate loan commitments were $1.7 billion at September 30, 2024, a $131 million increase compared to June 30, 2024. We take a disciplined approach to managing our concentration of commercial real estate loan commitments as a percentage of capital.

Loans to individuals increased $72 million and represent 16% of total loans. Residential mortgage loans increased $85 million while personal loans decreased $13 million.

1 See Explanation and Reconciliation of Non-GAAP Measures following.

The company's common equity Tier 1 capital ratio was 12.73% at September 30, 2024. In addition, the company's Tier 1 capital ratio was 12.74%, total capital ratio was 13.91%, and leverage ratio was 9.67% at September 30, 2024. At the beginning of 2020, we elected to delay the regulatory capital impact of the transition of the allowance for credit losses from the incurred loss methodology to CECL for two years, followed by a three-year transition period. This election added 3 basis points to the company's common equity Tier 1 capital ratio at September 30, 2024. At June 30, 2024, the company's common equity Tier 1 capital ratio was 12.10%, Tier 1 capital ratio was 12.11%, total capital ratio was 13.25%, and leverage ratio was 9.39%.

The company's tangible common equity ratio, a non-GAAP measure, was 9.22% at September 30, 2024, and 8.38% at June 30, 2024. The tangible common equity ratio is primarily based on total shareholders' equity, which includes unrealized gains and losses on available for sale securities. Adjusted for all unrealized securities portfolio gains and losses, including those in the investment portfolio, the tangible common equity ratio would be 9.01%.

No shares were repurchased during the third quarter of 2024. The company repurchased 412,176 shares of common stock at an average price paid of $90.38 a share in the second quarter of 2024. We view share buybacks opportunistically, but within the context of maintaining our strong capital position.

Credit Quality

Nonperforming assets totaled $87 million, or 0.36% of outstanding loans and repossessed assets, at September 30, 2024, compared to $93 million, or 0.38%, at June 30, 2024. Excluding loans guaranteed by U.S. government agencies, nonperforming assets totaled $80 million, or 0.34% of outstanding loans and repossessed assets, at September 30, 2024, compared to $86 million, or 0.35%, at June 30, 2024.

Nonaccruing loans decreased $6.4 million compared to June 30, 2024. New nonaccruing loans identified in the third quarter totaled $26 million, offset by $29 million in payments received and $2.5 million in charge-offs. Nonaccruing healthcare loans decreased $4.9 million and nonaccruing services loans decreased $1.7 million, partially offset by a $1.1 million increase in nonaccruing residential mortgage loans.

Net recoveries were $54 thousand, or less than 0.01% of average loans on an annualized basis, in the third quarter. Net charge-offs were $6.9 million, or 0.11% of average loans on an annualized basis, in the second quarter of 2024.

The provision for credit losses of $2.0 million in the third quarter of 2024 reflects continued strong credit quality, net loan paydowns, and relatively minor changes in economic forecast scenario assumptions. The provision for credit losses was $8.0 million in the second quarter of 2024.

BOK Financial Corporation quarterly earnings release Exhibit 99.1(a)

At September 30, 2024, the combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $332 million, or 1.39% of outstanding loans and 427% of nonaccruing loans. At June 30, 2024, the combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $330 million, or 1.34% of outstanding loans and 393% of nonaccruing loans.

Securities & Derivatives

The fair value of the available for sale securities portfolio totaled $13.0 billion at September 30, 2024, a $222 million increase compared to June 30, 2024. At September 30, 2024, the available for sale securities portfolio consisted primarily of $8.6 billion of residential mortgage-backed securities fully backed by U.S. government agencies and $3.4 billion of commercial mortgage-backed securities fully backed by U.S. government agencies. At September 30, 2024, the available for sale securities portfolio had a net unrealized loss of $307 million, compared to $649 million at June 30, 2024.

We hold an inventory of trading securities in support of sales to a variety of customers. At September 30, 2024, the trading securities portfolio totaled $5.1 billion, compared to $5.2 billion at June 30, 2024.

The company also maintains a portfolio of residential mortgage-backed securities issued by U.S. government agencies and interest rate derivative contracts as an economic hedge of the changes in the fair value of our mortgage servicing rights. This portfolio of fair value option securities increased $122 thousand to $19.2 million at September 30, 2024.

Derivative contracts are carried at fair value. At September 30, 2024, the net fair values of derivative contracts, before consideration of cash margin, reported as assets under our customer derivative programs totaled $415 million, compared to $339 million at June 30, 2024. The aggregate net fair value of derivative contracts, before consideration of cash margin, held under these programs reported as liabilities totaled $393 million at September 30, 2024, and $327 million at June 30, 2024.

The net cost of the changes in the fair value of mortgage servicing rights and related economic hedges was $4.5 million during the third quarter of 2024, including a $16.5 million decrease in the fair value of mortgage servicing rights, a $12.1 million increase in the fair value of securities and derivative contracts held as an economic hedge, and $146 thousand of related net interest expense.

Internal and external factors that might cause such a difference include, but are not limited to changes in government, 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, and trends in customer behavior as well as their ability to repay loans.

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. The adjusted tangible common equity ratio also includes unrealized gains and losses on the investment portfolio. 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.

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.

The efficiency ratio measures the company's ability to use its assets and manage its liabilities effectively in the current period.

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.

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.
