ST. LOUIS -- (Business Wire)

Enterprise Financial Services Corp (Nasdaq: EFSC) (the “Company” or “EFSC”) today announced financial results for the first quarter of 2026. “Our first quarter results demonstrated a stable net interest margin, improved credit quality, along with a strong balance sheet,” said Jim Lally, President and Chief Executive Officer. “With a 1.16% return on average assets, we continued to return capital to stockholders through an increased dividend and share repurchases. These fundamentally sound results represent a solid start to 2026, even accounting for seasonal loan and deposit trends. Given our capital strength and diversified model, we remain optimistic about the opportunities ahead in our markets.”

Comparisons to the prior year quarter are impacted by the acquisition of 12 branches in Arizona and Kansas in the fourth quarter 2025 (the “Branch Acquisition”).

Highlights

• Earnings - Net income in the first quarter 2026 was $49.4 million, a decrease of $5.4 million and $0.6 million compared to the linked and prior year quarters, respectively. Earnings per diluted common share for the first quarter 2026 was $1.30, compared to $1.45 and $1.31 for the linked and prior year quarters, respectively. Adjusted diluted earnings per share¹ was $1.31 in the current and prior year quarters, respectively, and $1.36 in the linked quarter.

• Pre-provision net revenue (“PPNR”)² - PPNR of $70.4 million in the first quarter 2026 decreased $4.4 million from the linked quarter and increased $4.3 million from the prior year quarter. The decrease from the linked quarter was primarily due to a decrease in net interest income due to a lower day count and noninterest income, specifically tax credit income that is typically highest in the fourth quarter of each year, and an increase in noninterest expense, primarily due to the reset of payroll tax limits and paid time-off accruals. The increase compared to the prior year quarter was primarily due to higher net interest income from organic and acquired loan growth, continued investment in the securities portfolio and proactive management of the cost of deposits, partially offset by a decline in asset yields due to lower short-term interest rates.

• Net interest income and NIM - Net interest income of $166.1 million for the first quarter 2026 decreased $2.0 million and increased $18.6 million from the linked and prior year quarters, respectively. Net interest income during the current quarter was impacted by lower short-term interest rates that decreased asset yields and fewer days in the period, partially offset by a favorable decrease on rates paid on interest-bearing liabilities. Compared to the prior year quarter, net interest income also benefitted from higher average loan and investment securities balances, and higher yields on the investment portfolio. NIM was 4.28% for the first quarter 2026, compared to 4.26% and 4.15% for the linked and prior year quarters, respectively. The total cost of deposits of 1.52% for the first quarter 2026 decreased 12 and 31 basis points from the linked and prior year quarters, respectively.

• Noninterest income - Noninterest income of $19.1 million for the first quarter 2026 decreased $6.3 million and increased $0.6 million from the linked and prior year quarters, respectively. The decrease in noninterest income from the linked quarter was primarily due to a gain on other real estate owned (“OREO”) in the linked quarter that did not reoccur and tax credit income, which is typically highest in the fourth quarter of each year, partially offset by a gain on the guaranteed portion of Small Business Administration (“SBA”) loans sold during the current quarter. The Company opportunistically sold $25.4 million of SBA guaranteed loans during the first quarter 2026 for a gain of $1.4 million.

• Noninterest expense - Noninterest expense of $115.1 million for the first quarter 2026 increased $0.6 million and $15.4 million from the linked and prior year quarters, respectively. The increase from the prior year quarter was primarily driven by higher employee compensation cost, variable deposit costs and loan and legal expenses related to loan workouts and OREO.

• Loans - Loans totaled $11.7 billion at March 31, 2026, a decrease of $107.6 million from the linked quarter and an increase of $394.0 million from the prior year quarter. Average loans totaled $11.8 billion for the current and linked quarters, respectively, and $11.2 billion for the prior year quarter.

• Asset quality - The allowance for credit losses to total loans was 1.21% at March 31, 2026, compared to 1.19% at December 31, 2025 and 1.27% at March 31, 2025. The provision for credit losses in the first quarter 2026 was $7.2 million, compared to $9.2 million and $5.2 million for the linked and prior year quarters, respectively. The ratio of nonperforming assets to total assets was 0.87% at March 31, 2026, compared to 0.95% and 0.72% at December 31, 2025 and March 31, 2025, respectively.

• Deposits - Deposits totaled $14.5 billion at March 31, 2026, a decrease of $84.9 million and an increase of $1.5 billion from the linked and prior year quarters, respectively. Average deposits were $14.6 billion, $14.5 billion and $13.1 billion for the current, linked and prior year quarters, respectively. At March 31, 2026, noninterest-bearing deposit accounts totaled $4.8 billion, or 33% of total deposits, and the loan to deposit ratio was 81%.

• Capital - Total stockholders’ equity was $2.0 billion and the tangible common equity to tangible assets ratio³ was 9.01% at March 31, 2026, compared to 9.07% at December 31, 2025. Enterprise Bank & Trust remains “well-capitalized,” with a common equity tier 1 ratio of 12.1% and a total risk-based capital ratio of 13.2% at March 31, 2026. The Company’s common equity tier 1 ratio and total risk-based capital ratio were 11.7% and 13.9%, respectively, at March 31, 2026.

The Company’s Board of Directors (the “Board”) approved a quarterly dividend of $0.34 per common share, payable on June 30, 2026 to stockholders of record as of June 15, 2026. The Board also declared a cash dividend of $12.50 per share of Series A Preferred Stock (or $0.3125 per depositary share) representing a 5% per annum rate for the period commencing (and including) March 15, 2026 to (but excluding) June 15, 2026. The dividend will be payable on June 15, 2026 to stockholders of record of Series A Preferred Stock as of May 29, 2026.

Net Interest Income and NIM

Average Balance Sheets

The following table presents, for the periods indicated, certain information related to the average interest-earning assets and interest-bearing liabilities, as well as the corresponding average interest rates earned and paid, all on a tax-equivalent basis.

Net interest income of $166.1 million for the first quarter 2026 decreased $2.0 million and increased $18.6 million from the linked and prior year quarters, respectively. Net interest income on a tax equivalent basis was $169.5 million, $171.7 million and $150.0 million for the current, linked and prior year quarters, respectively. The change from the linked and prior year quarters was related to the impact of lower short-term interest rates on loan yields and the cost of interest-bearing liabilities, in addition to growth in both interest-earning assets and interest-bearing liabilities. Net interest income also declined from the linked quarter due to two fewer days in the current quarter.

Since September 2024, the Federal Reserve has reduced the federal funds target rate 175 basis points. In response, the Company has proactively adjusted deposit pricing to partially mitigate the impact on income from the repricing of variable rate loans.

Interest income for the first quarter 2026 decreased $7.2 million and increased $13.3 million from the linked and prior year quarters, respectively. The decrease from the linked quarter was primarily due to a 13 basis point decrease in loan yields and two fewer days in the period, partially offset by a $158.9 million increase in average investment securities balances and an 11 basis point increase in yield on securities. The average interest rate of new loan originations in the first quarter 2026 was 6.58%, a decrease of 17 basis points from the linked quarter. Investment purchases in the first quarter 2026 had a weighted average, tax equivalent yield of 4.51%. Compared to the prior year quarter, interest-earning assets increased $1.4 billion.

Interest expense in the first quarter 2026 decreased $5.2 million and $5.3 million from the linked and prior year quarters, respectively, primarily due to a reduction in the cost of interest-bearing deposits due to decreased interest paid on interest-bearing deposits. The total cost of deposits, including noninterest-bearing demand accounts, was 1.52% during the first quarter 2026, compared to 1.64% and 1.83% in the linked and prior year quarters, respectively.

NIM, on a tax equivalent basis, was 4.28% in the first quarter 2026, an increase of two basis points and 13 basis points from the linked and prior year quarters, respectively. For the month of March 2026, the loan portfolio yield was 6.31% and the cost of total deposits was 1.50%.

Investments

Investment securities totaled $3.8 billion at March 31, 2026, an increase of $99.2 million from the linked quarter. The tangible common equity to tangible assets ratio adjusted for unrealized losses on HTM securities⁴ was 8.78% at March 31, 2026, compared to 8.91% at December 31, 2025.

Loans

The following table presents total loans for the most recent five quarters:

Loans totaled $11.7 billion at March 31, 2026, a decrease of $107.6 million compared to the linked quarter. Repayment activity outpaced loan production in the quarter with repayment activity of $921.1 million compared to loan volume of $813.5 million. Repayment activity was strongest in the tax credit and C&I portfolios in the current quarter. Loan sales of $25.4 million also mitigated growth in the SBA category during the current period. On a periodic basis, the Company will opportunistically sell SBA guaranteed loans. Average line utilization was approximately 45% for the current quarter, compared to 44% and 42% for the linked and prior year quarters, respectively.

Asset Quality

The following table presents the categories of nonperforming assets and related ratios for the most recent five quarters:

Nonperforming assets decreased $14.9 million and increased $36.3 million from the linked and prior year quarters, respectively. The decrease in nonperforming assets compared to the linked quarter is primarily due to two loans totaling $17.5 million that went on nonaccrual in the second half of 2025 and were subsequently paid off in the first quarter 2026. The increase in nonperforming assets from the prior year quarter is primarily related to one commercial real estate loan totaling $22.6 million that went on nonaccrual in the fourth quarter 2025. Four properties in OREO at March 31, 2026 with a carrying value of $46 million are currently under contract to sell.

The provision for credit losses totaled $7.2 million in the first quarter 2026, compared to $9.2 million and $5.2 million in the linked and prior year quarters, respectively. The provision for credit losses in the first quarter 2026 was primarily related to net charge-offs and qualitative adjustments to recognize the broader macroeconomic risks to the loan portfolio from the conflict in Iran. Annualized net charge-offs totaled 15 basis points of average loans in the current quarter, compared to 70 basis points in the linked quarter and annualized net recoveries totaled 4 basis points of average loans in the prior year quarter.

Deposits

The following table presents deposits broken out by type for the most recent five quarters:

Total deposits at March 31, 2026 were $14.5 billion, a decrease of $84.9 million and an increase of $1.5 billion from the linked and prior year quarters, respectively. Average deposits for the three months ended March 31, 2026 were $14.6 billion, compared to $14.5 billion and $13.1 billion for the three months ended December 31, 2025 and March 31, 2025, respectively. Reciprocal deposits, which are placed through third party programs to provide FDIC insurance on larger deposit relationships, totaled $1.3 billion and $1.4 billion at March 31, 2026 and December 31, 2025, respectively.

Noninterest Income

The following table presents a comparative summary of the major components of noninterest income for the periods indicated:

Total noninterest income was $19.1 million for the first quarter 2026, a decrease of $6.3 million and an increase of $0.6 million from the linked and prior year quarters, respectively. The decrease from the linked quarter was primarily due to a seasonal decrease in tax credit income and a gain on OREO in the linked quarter that did not reoccur, partially offset by higher private equity fund distributions and a gain on the sale of the guaranteed portion of SBA loans included in other income. Compared to the prior year quarter, tax credit income decreased $2.8 million, partially offset by higher BOLI income and private equity fund distributions. Tax credit income varies based on transaction volumes and fair value changes on credits carried at fair value.

The following table presents a comparative summary of the major components of other income for the periods indicated:

The decrease in other income from the linked quarter was primarily due to a $6.2 million net gain on OREO in the linked quarter that did not reoccur, partially offset by a $1.6 million increase in private equity fund distributions, a $1.4 million gain on the sale of $25.4 million of guaranteed SBA loans, and the payout of a BOLI policy that increased BOLI income in the current quarter.

Compared to the prior year quarter, other income increased $2.4 million primarily driven by an increase of $1.7 million in BOLI income due to the purchase of additional life insurance policies, and to a lesser extent, the payout of a BOLI policy, as well as a $1.2 million increase in private equity fund distributions. Private equity fund distributions are not a consistent source of income and fluctuate based on distributions from the underlying funds.

Noninterest Expense

The following table presents a comparative summary of the major components of noninterest expense for the periods indicated:

Noninterest expense increased $0.6 million and $15.4 million from the linked and prior year quarters, respectively. Employee compensation and benefits increased $5.6 million from the linked quarter primarily due to the first quarter reset of payroll taxes and paid time-off accruals, along with annual merit increases that became effective March 1, 2026. Deposit costs relate to certain businesses in the deposit verticals that receive an earnings credit allowance for deposit-related services provided to us. These earnings credit allowances are impacted by, among other things, interest rates and average balances. Deposit costs decreased $1.5 million from the linked quarter primarily due to the expiration of certain allowances that were not used. The decline in acquisition costs from the linked quarter is due to the completion of the Branch Acquisition that closed in the fourth quarter 2025.

The increase in noninterest expense from the prior year quarter was primarily due to an increase in the associate base as a result of the Branch Acquisition, merit increases throughout 2025 and 2026, an increase of $2.2 million in deposit costs due to higher earnings credit allowances and deposit vertical average balances, and an increase of $1.8 million in loan and legal expenses due to loan workouts and the foreclosure of certain properties. For the first quarter 2026, the core efficiency ratio⁵ was 60.2%, compared to 58.3% for the linked quarter and 58.8% for the prior year quarter.

Income Taxes

The effective tax rate for the current and linked quarters was 21.5%, respectively, compared to 18.1% in the prior year quarter. The increase in the effective tax rate from the prior year quarter was due to an increase in state taxes from apportionment factors and a decrease in tax credit investments.

Capital

The following table presents total equity and various capital ratios for the most recent five quarters:

Total equity was $2.0 billion at March 31, 2026, a decrease of $17.2 million and an increase of $154.1 million from the linked and prior year quarters, respectively. Tangible book value per common share⁵ was $41.38 at March 31, 2026, compared to $41.37 and $38.54 at December 31, 2025 and March 31, 2025, respectively. The Company repurchased 483,000 shares at an average price of $56.13 in the first quarter 2026. The Company has 631,483 shares remaining under a Board-approved stock repurchase plan.

The Company’s regulatory capital ratios continue to exceed the “well-capitalized” regulatory benchmark. Capital ratios for the current quarter are subject to, among other things, completion and filing of the Company’s regulatory reports and ongoing regulatory review.

Use of Non-GAAP Financial Measures

The Company’s accounting and reporting policies conform to generally accepted accounting principles in the United States (“GAAP”) and the prevailing practices in the banking industry. However, the Company provides other financial measures, such as tangible common equity, PPNR, ROATCE, adjusted ROATCE, core efficiency ratio, tangible common equity to tangible assets ratio, tangible common equity to tangible assets ratio adjusted for unrealized losses on held-to-maturity securities, tangible book value per common share, return on average common equity, adjusted return on average common equity, allowance for credit losses to total loans excluding guaranteed loans, adjusted ROAA, and adjusted diluted earnings per share, in this release that are considered “non-GAAP financial measures.” Generally, a non-GAAP financial measure is a numerical measure of a company’s financial performance, financial position, or cash flows that exclude (or include) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP.

The Company considers its tangible common equity, PPNR, ROATCE, adjusted ROATCE, core efficiency ratio, tangible common equity to tangible assets ratio, tangible common equity to tangible assets ratio adjusted for unrealized losses on held-to-maturity securities, tangible book value per common share, return on average common equity, adjusted return on average common equity, allowance for credit losses to total loans excluding guaranteed loans, adjusted ROAA and adjusted diluted earnings per share, collectively “core performance measures,” presented in this earnings release and the included tables as important measures of financial performance, even though they are non-GAAP measures, as they provide supplemental information by which to evaluate the impact of certain non-comparable items, and the Company’s operating performance on an ongoing basis. Core performance measures exclude certain other income and expense items, such as the FDIC special assessment, acquisition costs, accrued insurance proceeds anticipated to be received as a result of recaptured tax credits, the net gain or loss on OREO and the net gain or loss on sales of investment securities, that the Company believes to be not indicative of or useful to measure the Company’s operating performance on an ongoing basis. The attached tables contain a reconciliation of these core performance measures to the GAAP measures. The Company believes that the tangible common equity to tangible assets ratio provides useful information to investors about the Company’s capital strength even though it is considered to be a non-GAAP financial measure and is not part of the regulatory capital requirements to which the Company is subject.

The Company believes these non-GAAP measures and ratios, when taken together with the corresponding GAAP measures and ratios, provide meaningful supplemental information regarding the Company’s performance and capital strength. The Company’s management uses, and believes that investors benefit from referring to, these non-GAAP measures and ratios in assessing the Company’s operating results and related trends and when forecasting future periods. However, these non-GAAP measures and ratios should be considered in addition to, and not as a substitute for or preferable to, ratios prepared in accordance with GAAP. In the attached tables, the Company has provided a reconciliation of, where applicable, the most comparable GAAP financial measures and ratios to the non-GAAP financial measures and ratios, or a reconciliation of the non-GAAP calculation of the financial measures for the periods indicated.
