BOK Financial Corporation reports quarterly earnings of $164 million, or $2.54 per share, in the second quarter.

Second quarter 2024 financial highlights 1
Net Income |  | Net income was $163.7 million or $2.54 per diluted share compared to $83.7 million or $1.29 per diluted share. Excluding the gain on conversion of Visa shares, the additional FDIC special assessment expense and the contribution of Visa shares to the BOKF Foundation, net income would have been $131.1 million or $2.02 per share for the second quarter of 2024.2
Net Interest Income & Margin |  | Net interest income totaled $296.0 million, an increase of $2.4 million. Net interest margin was 2.56% compared to 2.61%.
Fees & Commissions Revenue |  | Fees and commissions revenue was $200.0 million, consistent with the prior quarter. Higher fiduciary and asset management revenue and transaction card revenue was offset by lower brokerage and trading revenue.
Operating Expense |  | Operating expense decreased $3.7 million to $336.7 million, primarily due to a reduction in personnel expense with lower incentive compensation, including deferred compensation plans, regular compensation, and employee benefits. Non-personnel expense increased $7.9 million, largely due to our contribution of Visa shares valued at $10.0 million to the BOKF Foundation.
Loans |  | Period end loans grew by $381 million to $24.6 billion at June 30, 2024, mostly driven by growth in commercial loans, partially offset by a reduction in commercial real estate loans. Average outstanding loan balances were $24.4 billion, a $437 million increase.
Credit Quality |  | Nonperforming assets totaled $93 million or 0.38% of outstanding loans and repossessed assets at June 30, 2024, compared to $122 million or 0.51% at March 31, 2024. Net charge-offs were $6.9 million or 0.11% of average loans on an annualized basis in the second quarter.
Deposits |  | Period end deposits increased $858 million to $36.2 billion while average deposits increased $627 million to $35.7 billion.

CEO Commentary
“BOK Financial once again produced very strong quarterly results, led by our robust commercial and industrial loan growth — a result of our team’s sales efforts and a footprint in states with outstanding economic growth. We continue to grow thoughtfully, taking advantage of current market uncertainty and our robust capital and liquidity levels, while maintaining a disciplined credit culture. This credit culture is foundational to who we are and continues to yield exceptional performance. We also realized gains in our Visa B stock during the quarter, a positive outcome that highlights our patience and long-term approach to generating shareholder value. We have a sustainable business model with a leading mix of core fee businesses while also doing an exemplary job of risk management, evidenced by tangible capital, liquidity, and a commercial real estate concentration being meaningfully favorable to peers.”

Net interest income was $296.0 million for the second quarter of 2024 compared to $293.6 million for the prior quarter. Net interest margin was 2.56% compared to 2.61%. The pace of demand deposit migration and deposit repricing has slowed compared to the previous quarter and was offset by improving yields on the available for sale securities portfolio.

Average earning assets increased $1.2 billion. Average loan balances increased $437 million, largely due to growth in commercial loans, partially offset by a reduction in commercial real estate loan balances. Average available for sale securities grew $218 million while average trading securities increased $552 million. Average interest-bearing deposits increased $872 million, primarily from interest-bearing transaction accounts. Funds purchased and repurchase agreements grew $580 million while average other borrowings increased $307 million.

Brokerage and trading revenue decreased $6.2 million to $53.0 million. Trading revenue decreased $9.8 million to $27.7 million as margins compressed due to market conditions in the second quarter of 2024. Investment banking revenue grew $3.0 million from increased underwriting and syndication fees.
Fiduciary and asset management revenue increased $2.3 million to $57.6 million, led by higher seasonal tax preparation fee income. Transaction card revenue grew $1.8 million to $27.2 million, primarily due to an increase in the volume of transactions processed during the second quarter of 2024.
Other gains, net, increased $53.1 million to $57.4 million. The second quarter of 2024 included a $53.8 million pre-tax gain on the conversion of our Visa B shares under the recently announced exchange offer by Visa, Inc. The gain offsets losses of $45.2 million on the repositioning of the available for sale securities portfolio realized in the first quarter of 2024. We donated 35,620 of the converted Visa shares valued at $10.0 million to the BOKF Foundation during the second quarter of 2024, allowing us to further invest in the communities we serve.

Personnel expense was $191.1 million, a decrease of $11.6 million. Incentive compensation expense decreased $7.7 million due to a decrease in deferred compensation expense and a shift in the timing of expense recognition as commercial incentive compensation plans move to being primarily share-based rather than cash-based awards. Employee benefits expense decreased $2.0 million due to a seasonal decrease in payroll taxes, partially offset by higher healthcare costs. Regular compensation decreased $1.9 million. A greater amount of compensation expense was capitalized during the second quarter due to an annual update of the standard costs for loan originations coupled with an increase in mortgage loan production volume.
Non-personnel expense was $145.6 million, an increase of $7.9 million. In addition to the $10 million share donation previously mentioned, we also made a $3.6 million contribution to the BOKF Foundation in the second quarter of 2024. Mortgage banking costs increased $2.2 million due to higher seasonal prepayments, and a rise in professional fees and services expense of $1.3 million was primarily due to project related expense. In the second quarter of 2024, we recognized $1.2 million of expense related to the FDIC special assessment estimate compared to $6.5 million of expense in the prior quarter. Other expense decreased $3.0 million, primarily due to lower operational losses.

Total loans |  | $ | 24,553,581 |  | $ | 24,172,560 |  | $ | 381,021 |  | 1.6%

Outstanding loans were $24.6 billion at June 30, 2024, growing $381 million over March 31, 2024, largely due to growth in commercial loans, partially offset by a reduction in commercial real estate loans. Unfunded loan commitments decreased $319 million compared to the first quarter of 2024.
Outstanding commercial loan balances, which includes healthcare, services, energy and general business loans, increased $491 million over the prior quarter.
General business loans increased $450 million to $4.4 billion or 18% of total loans. General business loans include $2.7 billion of wholesale/retail loans and $1.6 billion of loans from other commercial industries.
Services sector loan balances increased $48 million to $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.
Energy loan balances increased $7.8 million to $3.5 billion or 14% 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 $4.4 billion at June 30, 2024, a $20 million increase over March 31, 2024.
Healthcare sector loan balances decreased $15 million, totaling $4.2 billion or 17% of total loans. Our healthcare sector loans primarily consist of $3.5 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 $153 million to $5.1 billion and represent 21% of total loans. Loans secured by industrial facilities decreased $129 million to $1.2 billion. Other real estate loans decreased $45 million to $358 million, and loans secured by office facilities decreased $24 million to $877 million. These decreases were partially offset by a $36 million increase in loans secured by multifamily properties. Unfunded commercial real estate loan commitments were $1.6 billion at June 30, 2024, an $88 million decrease compared to March 31, 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 $44 million and represent 16% of total loans. Residential mortgage loans increased $81 million while personal loans decreased $37 million.

The company's common equity Tier 1 capital ratio was 12.10% at June 30, 2024. In addition, the company's Tier 1 capital ratio was 12.11%, total capital ratio was 13.25%, and leverage ratio was 9.39% at June 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 June 30, 2024. At March 31, 2024, the company's common equity Tier 1 capital ratio was 11.99%, Tier 1 capital ratio was 12.00%, total capital ratio was 13.15%, and leverage ratio was 9.42%.
The company's tangible common equity ratio, a non-GAAP measure, was 8.38% at June 30, 2024 and 8.21% at March 31, 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 8.06%.
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 $93 million or 0.38% of outstanding loans and repossessed assets at June 30, 2024, compared to $122 million or 0.51% at March 31, 2024. Excluding loans guaranteed by U.S. government agencies, nonperforming assets totaled $86 million or 0.35% of outstanding loans and repossessed assets at June 30, 2024, compared to $113 million or 0.47% at March 31, 2024.
Nonaccruing loans decreased $29 million compared to March 31, 2024. New nonaccruing loans identified in the second quarter totaled $24 million, offset by $42 million in payments received and $7.9 million of charge-offs.

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.
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.
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.
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.
