Overview

On January 31, 2025, UMBF completed its previously announced acquisition of Heartland Financial, USA, Inc. (HTLF). The acquisition added assets with a fair value of approximately $16.1 billion, $9.7 billion of loans, net of the allowance for credit losses, and $14.3 billion of deposits. The combined company retains its #1 deposit market share in Missouri and now ranks in the top 10 in Colorado, New Mexico, Kansas, and Arizona.

The Company focuses on the following four core financial objectives. Management believes these objectives will guide its efforts to achieve its vision, to deliver the Unparalleled Customer Experience, all while seeking to improve net income and strengthen the balance sheet while undertaking prudent risk management.

The first financial objective is to continuously improve operating efficiencies. The Company has focused on identifying efficiencies that simplify our organizational and reporting structures, streamline back-office functions, and take advantage of synergies and newer technologies among various platforms and distribution networks. The Company has identified and expects to continue identifying ongoing efficiencies through the normal course of business that, when combined with increased revenue, will contribute to improved operating leverage. During the second quarter of 2026, total revenue increased $88.8 million, or 12.9%, as compared to the second quarter of 2025, while noninterest expense increased $6.5 million, or 1.6%, for the same period. Included in noninterest expense for the second quarter of 2025 is $13.5 million in acquisition-related expense compared to $1.7 million in the second quarter of 2026. Revenue is also impacted by accretion and amortization of the fair value adjustments discussed in Note 13, “Acquisition” above. As part of the initiative to improve operating efficiencies, the Company continues to invest in technological advances that it believes will help management drive operating leverage in the future through improved data analysis and automation. The Company also continues to evaluate core systems and will invest in enhancements that it believes will yield operating efficiencies.

The second financial objective is to increase net interest income through profitable loan and deposit growth and the optimization of the balance sheet. During the second quarter of 2026, the Company had an increase in net interest income of $65.5 million, or 14.0%, from the same period in 2025. The change in net interest income was primarily driven by favorable repricing of deposits in conjunction with lower short-term interest rates, and increases of $4.2 billion, or 11.6%, in average loans and $2.2 billion, or 12.6%, in average securities. These increases were partially offset by a decrease of $2.9 billion, or 44.3%, in average interest-bearing due from banks and $6.3 million in lower purchase accounting accretion income. The funding for these assets was driven by an increase in average interest-bearing deposits of 3.9%, and an increase in noninterest-bearing demand deposit balances of 2.1% compared to the second quarter of 2025. Net interest margin, on a tax-equivalent basis, increased 22 basis points compared to the same period in 2025, primarily driven by favorable repricing of deposits in conjunction with lower short-term interest rates. Net interest spread increased 34 basis points during the same period. The Company expects to see continued volatility in the economic markets resulting from governmental responses to inflation and recessionary signs in the economy, as well as uncertainty about the impacts of the conflict in Iran and tariffs. These changing conditions could have impacts on the balance sheet and income statement of the Company for the remainder of the year.

The third financial objective is to grow the Company’s revenue from noninterest sources. The Company seeks to grow noninterest revenues throughout all economic and interest rate cycles, while positioning itself to benefit in periods of economic growth. Noninterest income increased $23.3 million, or 10.5%, to $245.5 million for the three months ended June 30, 2026, compared to the same period in 2025. See greater detail below under Noninterest Income. The Company continues to emphasize its asset management, brokerage, bankcard services, healthcare services, and treasury management businesses. For the three months ended June 30, 2026, noninterest income represented 31.6% of total revenue, compared to 32.2% for the same period in 2025. The recent economic changes have impacted fee income, especially those with assets tied to market values and interest rates.

The fourth financial objective is effective capital management. The Company places a significant emphasis on maintaining a strong capital position, which management believes promotes investor confidence, provides access

69

to funding sources under favorable terms, and enhances the Company’s ability to capitalize on business growth and acquisition opportunities. The Company continues to maximize shareholder value through a mix of reinvesting in organic growth, evaluating acquisition opportunities that complement the Company’s strategies, increasing dividends over time, and appropriately utilizing a share repurchase program. At June 30, 2026, the Company had $8.0 billion in total shareholders’ equity. This is an increase of $745.0 million, or 10.2%, compared to total shareholders’ equity at June 30, 2025. At June 30, 2026, the Company had a total risk-based capital ratio of 13.80%. The Company repurchased 38,158 shares of common stock during the second quarter of 2026 at an average price of $132.10. The Company also acquired shares pursuant to the Company's share-based incentive programs.

See Note 13, “Acquisition” above. The remainder of the increase in provision was driven by loan growth, portfolio credit metric changes, and ongoing recalibrations of economic loss models in the current period as compared to the prior periods. The Company’s nonperforming loans increased $30.5 million to $127.5 million at June 30, 2026, compared to June 30, 2025.

Net Interest Income

Net interest income is a significant source of the Company’s earnings and represents the amount by which interest income on earning assets exceeds the interest expense paid on liabilities. The volume of interest-earning assets and the related funding sources, the overall mix of these assets and liabilities, and the rates paid on each affect net interest income. Net interest income for the three and six-month periods ended June 30, 2026 increased $65.5 million, or 14.0%, and increased $202.2 million, or 23.4%, compared to the same periods in 2025. The change in net interest income was primarily driven by favorable repricing of deposits in conjunction with lower short-term interest rates, and increases in average loans and average securities. These increases were partially offset by decreases in average interest-bearing due from banks and purchase accounting accretion income.

Table 1 shows the impact of earning asset rate changes compared to changes in the cost of interest-bearing liabilities. As illustrated in this table, net interest spread for the three months ended June 30, 2026 increased 34 basis points as compared to the same period in 2025. Net interest margin for the three months ended June 30, 2026 increased 22 basis points compared to the same period in 2025. Net interest spread for the six-month period ended June 30, 2026 increased by 44 basis points as compared to the same period in 2025. Net interest margin for the six-month period ended June 30, 2026 increased by 31 basis points compared to the same period in 2025. The change is driven by favorable repricing of deposits in conjunction with lower short-term interest rates. The cost of interest-bearing liabilities decreased 54 basis points from the second quarter of 2025 while the yield on earning assets decreased 20 basis points compared to the same period. The cost of interest-bearing liabilities decreased 54 basis points for the six-month period ended June 30, 2026 as compared to the same period in 2025 while the yield on earning assets decreased 10 basis points compared to the same period. Earning asset balance increases have been primarily driven by higher average loans and increased securities balances, partially offset by decreased interest-bearing due from banks balances. These variances have led to an increase in the Company’s net interest income during 2026, as compared to results for the same periods in 2025. The Company expects to see continued volatility in the economic markets and governmental responses to changes in the economy. These changing conditions could have impacts on the balance sheet and income statement of the Company for the remainder of the year. For the impact of the contribution from free funds, see the Analysis of Net Interest Margin within Table 2 below. Table 2 also illustrates how the changes in volume and interest rates have resulted in an increase in net interest income.

Table 1

AVERAGE BALANCE SHEETS/YIELDS AND RATES (tax-equivalent basis) (unaudited, dollars in thousands)

The following table presents, for the periods indicated, the average earning assets and resulting yields, as well as the average interest-bearing liabilities and resulting yields, expressed in both dollars and rates. All average balances are daily average balances. The average yield on earning assets without the tax-equivalent basis adjustment would have been 5.35% for the three-month period ended June 30, 2026, and 5.55% for the same period in 2025. The average yield on earning assets without the tax-equivalent basis adjustment would have been 5.37% for the six-month period ended June 30, 2026, and 5.48% for the same period in 2025.
