CEO Commentary
Stacy Kymes, President and CEO, stated, “Second quarter results highlighted the strength of our team and the effectiveness of our diverse business model. We gained momentum this quarter driven by accelerated loan growth, strong fee income performance and continued margin expansion. Loans grew over $600 million, or 10% annualized, as we leveraged our strong liquidity and capital position, all while maintaining exceptional credit quality. Net interest income grew for the fifth consecutive quarter and core net interest margin, excluding trading, expanded another 7 basis points. Fee income was another standout, with broad-based growth and record quarterly highs in fiduciary and asset management revenue, transaction card revenue, and deposit service charges. This growth reinforces our confidence in our ability to deliver consistent, high-quality performance in the face of evolving market conditions."

The company's common equity Tier 1 capital ratio was 13.59% at June 30, 2025. In addition, the company's Tier 1 capital ratio was 13.60%, total capital ratio was 14.48%, and leverage ratio was 9.88% at June 30, 2025. At March 31, 2025, the company's common equity Tier 1 capital ratio was 13.31%, Tier 1 capital ratio was 13.31%, total capital ratio was 14.54%, and leverage ratio was 10.02%.
The company's tangible common equity ratio, a non-GAAP measure, was 9.63% at June 30, 2025, and 9.48% at March 31, 2025. 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 9.40%.
The company repurchased 663,298 shares of common stock at an average price paid of $93.99 per share in the second quarter of 2025. We view buybacks opportunistically, but within the context of maintaining our strong capital position.
Credit Quality
Nonperforming assets totaled $81 million, or 0.33% of outstanding loans and repossessed assets, at June 30, 2025, compared to $85 million, or 0.36%, at March 31, 2025. Excluding loans guaranteed by U.S. government agencies, nonperforming assets totaled $74 million, or 0.31% of outstanding loans and repossessed assets, at June 30, 2025, compared to $79 million, or 0.33%, at March 31, 2025.
Nonaccruing loans decreased $4.2 million compared to March 31, 2025. New nonaccruing loans identified in the second quarter totaled $8.1 million, offset by $11 million in payments received and $1.3 million in charge-offs. Nonaccruing commercial real estate loans decreased $6.2 million and nonaccruing services loans decreased $2.3 million. This was partially offset by a $4.6 million increase in nonaccruing personal loans.
Net charge-offs were $561 thousand, or 0.01% of average loans on an annualized basis, in the second quarter. Net charge-offs were $1.1 million, or 0.02% of average loans on an annualized basis, in the first quarter of 2025.
No provision for expected credit losses was necessary for the second quarter of 2025, primarily due to further improvements in portfolio credit quality offset by the impact of loan growth during the quarter.
At June 30, 2025, the combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $330 million, or 1.36% of outstanding loans and 456% of nonaccruing loans, excluding residential mortgage loans guaranteed by U.S. government agencies. At March 31, 2025, the combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $331 million, or 1.40% of outstanding loans and 431% of nonaccruing 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.
The adjusted common equity Tier 1 ratio includes accumulated other comprehensive loss and unrealized gains and losses on the investment portfolio. This measure is a valuable indicator of a financial institution’s capital strength and retains 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.
