BOK Financial Corporation reports quarterly earnings of $84 million, or $1.29 per share, in the first quarter.

First quarter 2024 financial highlights 1
Net Income |  | Net income was $83.7 million or $1.29 per diluted share compared to $82.6 million or $1.26 per diluted share. Excluding the loss from repositioning of the available for sale securities portfolio and the additional FDIC special assessment expense, net income would have been $123.2 million or $1.91 per share for the first quarter of 2024.
Net Interest Revenue & Margin |  | Net interest revenue totaled $293.6 million, a decrease of $3.1 million. Net interest margin was 2.61% compared to 2.64%.
Fees & Commissions Revenue |  | Fees and commissions revenue was $200.6 million, an increase of $3.8 million. Higher mortgage banking and fiduciary and asset management revenue was partially offset by lower brokerage and trading and transaction card revenue.
Operating Expense |  | Operating expense decreased $43.7 million to $340.4 million, primarily due to a reduction in non-personnel expense resulting from the FDIC special assessment recognized in the fourth quarter of 2023. Personnel expense was relatively consistent with the prior quarter.
Loans |  | Period end loans grew by $268 million to $24.2 billion at March 31, 2024, mostly driven by growth in commercial loans, partially offset by a reduction in commercial real estate loans. Average outstanding loan balances were $23.9 billion, a $243 million increase.
Credit Quality |  | Nonperforming assets totaled $122 million or 0.51% of outstanding loans and repossessed assets at March 31, 2024, compared to $148 million or 0.62% at December 31, 2023. Net charge-offs were $5.5 million or 0.09% of average loans on an annualized basis in the first quarter.

CEO Commentary
First quarter results were characterized by a stabilizing net interest margin, strong asset quality, continued strong operating revenue growth, and well-managed expenses. It is also another reflection of our long-term focus and efforts to create sustainable earnings. While many banks sold their VISA B shares at a considerable discount, we chose to retain the shares we received in 2008 and expect to receive full value in VISA’s announced exchange offer. Given our perception of market spreads, we took an opportunity to reposition the securities portfolio in the first quarter in anticipation of a gain in the second quarter this year from monetizing our VISA B shares. The net result is expected to further improve our net interest margin and net interest revenue outlook in future periods. Commercial loans grew almost 9% annualized as we focus on growth to utilize our strong capital and liquidity levels as others retrench. Our credit metrics remain very strong and are a direct reflection of the focus we put on disciplined risk management. I am also exceptionally proud we were recognized as one of only 60 organizations to receive the 2024 Gallup Exceptional Workplace Award. This is independent validation of our culture of inspiration, ambition, collaboration, and tenacity.

Net interest revenue was $293.6 million for the first quarter of 2024 compared to $296.7 million for the prior quarter.

Average earning assets increased $520 million.

Average interest-bearing deposits increased $2.1 billion, primarily from interest-bearing transaction accounts.

Fiduciary and asset management revenue increased $3.9 million to $55.3 million, primarily due to growth in trust business line fees resulting from movement in the equity markets.
Brokerage and trading revenue decreased $1.7 million to $59.2 million. Trading revenue grew $1.9 million to $37.5 million reflecting increased trading activity primarily in U.S. government agency residential mortgage-backed securities.
Insurance brokerage fees decreased $1.8 million in conjunction with the sale of our insurance brokerage and consulting business, BOK Financial Insurance (“BOKFI”) in the fourth quarter. Customer hedging revenue decreased $1.3 million, largely as result of reduced energy customer hedging volumes.
Transaction card revenue decreased $3.4 million to $25.5 million, primarily due to seasonally elevated fourth quarter activity and one less day in the quarter.
Other revenue decreased $2.1 million, largely due to a reduction in fees earned on derivative counterparty margin.
Other gains, net decreased $36.2 million to $4.3 million. The fourth quarter of 2023 included a $31.0 million pre-tax gain, before related professional fees, on the sale of BOKFI.
Losses on available for sale securities were $45.2 million in the first quarter of 2024 as we repositioned the available for sale securities portfolio by selling approximately $783 million of lower-yielding debt securities. We expect the gain on conversion of our Visa B shares under the recently announced exchange offer by Visa, Inc. will offset the realized losses on the repositioning. The Visa Exchange Offer opened on April 8 and is scheduled to expire at end of day on May 3, 2024.

During the first quarter of 2024, we received notification from the FDIC that the previous assessed losses attributable to the protection of Silicon Valley Bank and Signature Bank uninsured depositors had increased, so an additional $6.5 million of estimated expense related to the special assessment was recognized.
Professional fees and services expense decreased $4.3 million. The previous quarter included $2.2 million in expenses related to the sale of BOKFI.
Other expense was up $2.4 million, primarily due to increased operational losses.

Outstanding loans were $24.2 billion at March 31, 2024, growing $268 million over December 31, 2023, largely due to growth in commercial loans, partially offset by a reduction in commercial real estate loans. Unfunded loan commitments decreased $359 million compared to the fourth quarter of 2023.
Outstanding commercial loan balances, which includes healthcare, services, energy and general business loans, increased $329 million over the prior quarter.
Healthcare sector loan balances increased $103 million, totaling $4.2 billion or 18% 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.
General business loans increased $267 million to $3.9 billion or 16% of total loans. General business loans include $2.4 billion of wholesale/retail loans and $1.5 billion of loans from other commercial industries.
Services sector loan balances decreased $47 million to $3.5 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 were largely unchanged compared to the prior quarter at $3.4 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 $4.3 billion at March 31, 2024, a $147 million decrease compared to December 31, 2023.

Loans secured by industrial facilities decreased $131 million to $1.3 billion and loans secured by retail facilities decreased $49 million to $544 million. These decreases were partially offset by an $88 million increase in loans secured by multifamily properties. Unfunded commercial real estate loan commitments were $1.7 billion at March 31, 2024, a decrease of $147 million compared to December 31, 2023. We take a disciplined approach to managing our concentration of commercial real estate loan commitments as a percentage of capital.

1 See Explanation and Reconciliation of Non-GAAP Measures following.
The company's common equity Tier 1 capital ratio was 11.99% at March 31, 2024. In addition, the company's Tier 1 capital ratio was 12.00%, total capital ratio was 13.15%, and leverage ratio was 9.42% at March 31, 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 March 31, 2024. At December 31, 2023, the company's common equity Tier 1 capital ratio was 12.06%, Tier 1 capital ratio was 12.07%, total capital ratio was 13.16%, and leverage ratio was 9.45%.
The company's tangible common equity ratio, a non-GAAP measure, was 8.21% at March 31, 2024 and 8.29% at December 31, 2023. 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 7.92%. The company has elected to exclude unrealized gains and losses from available for sale securities from its calculation of Tier 1 capital for regulatory capital purposes, consistent with the treatment under the previous capital rules.
The company repurchased 616,630 shares of common stock at an average price paid of $83.89 a share in the first quarter of 2024. We view share buybacks opportunistically, but within the context of maintaining our strong capital position.

decreases in other expense and professional fees. Average loans increased $139 million or 1% to $20.1 billion. Average deposits increased $237 million or 2% to $15.7 billion.
Consumer Banking contributed $53.8 million to net income in the first quarter of 2024, consistent with the prior quarter. Combined net interest revenue and fee revenue decreased $6.1 million, largely due to increased customer demand for time deposits and a reduction in deposit spreads from a change in market conditions, partially offset by an increase in mortgage banking revenue from higher production volumes. Operating expense decreased $1.6 million. The net benefit of the changes in the fair value of mortgage servicing rights and related economic hedges was $1.2 million compared to a net cost of $5.2 million for the fourth quarter of 2023.

The prior quarter included a pre-tax gain of $31.0 million, before related professional fees, on the sale of our insurance brokerage and consulting business, BOKFI. Combined net interest and fee revenue decreased $2.7 million due to declining spread on deposits. Total revenue from institutional trading activities increased $1.4 million, primarily in U.S. government residential mortgage-backed securities trading activity. Personnel expense decreased $2.4 million as the prior quarter included transaction related employee costs on the BOKFI sale. Non-personnel expense increased $5.6 million, primarily due to an increased level of operational losses, partially offset by a $2.7 million decrease in professional fees. Average loans increased $44 million or 2% to $2.2 billion. Average deposits increased $1.2 billion or 14% to $9.2 billion. Assets under management or administration were $105.5 billion, an increase of $794 million.

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 revenue 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.
