St. Louis, MO. October 27, 2025 – Enterprise Financial Services Corp (Nasdaq: EFSC) (the “Company” or “EFSC”) today announced financial results for the third quarter of 2025. “Our third quarter results demonstrated solid loan and deposit growth, along with continued expansion in net interest income and net interest margin. We have successfully increased net interest income for the past six consecutive quarters, highlighting the efforts of our team,” said Jim Lally, President and Chief Executive Officer. “Earlier this month we announced the completion of the acquisition of 10 branches in Arizona and two in Kansas. This acquisition increases our presence in these markets and strengthens our ability to service our customers while enhancing our funding profile.”

Highlights

•Earnings - Net income in the third quarter 2025 was $45.2 million, a decrease of $6.1 million and $5.4 million compared to the linked and prior year quarters, respectively. Earnings per diluted common share for the third quarter 2025 was $1.19, compared to $1.36 and $1.32 for the linked and prior year quarters, respectively. Adjusted diluted earnings per share1 was $1.20 in the third quarter 2025, compared to $1.37 and $1.29 in the linked and prior year quarters, respectively.

Noninterest income for the third quarter 2025 included $30.1 million of anticipated insurance proceeds from a pending claim related to a recapture event during the quarter with respect to a $24.1 million solar tax credit that the Company purchased and applied to prior taxable periods. The anticipated proceeds from the insurance policy and tax liability resulting from the recapture event, both totaling $30.1 million, are included in “Noninterest Income” and “Income Tax Expense”, respectively, in the Condensed Consolidated Statements of Income for the three and nine months ended September 30, 2025.

1 ROATCE, tangible common equity to tangible assets, tangible book value per common share and adjusted diluted earnings per share are non-GAAP measures. Please refer to discussion and reconciliation of these measures in the accompanying financial tables.


•Pre-provision net revenue (“PPNR”)2 - PPNR of $65.6 million in the third quarter 2025 decreased $2.5 million from the linked quarter and was relatively stable with the prior year quarter. Excluding the anticipated insurance proceeds from the tax credit recapture included in noninterest income, the change from the linked and prior year quarters was primarily due to a decrease in noninterest income and an increase in noninterest expense, partially offset by higher net interest income from higher average balances in the loan and securities portfolios.

•Net interest income and NIM - Net interest income of $158.3 million for the third quarter 2025 increased $5.5 million and $14.8 million from the linked and prior year quarters, respectively. Net interest income increased primarily due to higher average loan balances, higher average securities balances and yields, and lower short-term interest rates that decreased deposit interest expense. NIM was 4.23% for the third quarter 2025, compared to 4.21% and 4.17% for the linked and prior year quarters, respectively. On September 2, 2025, the Company redeemed $63.3 million of subordinated debt that had a floating rate of three-month Term SOFR plus a spread of 5.66%. The redemption was funded through the issuance of a $63.3 million senior note at a rate of one-month Term SOFR plus a spread of 2.50%. The total cost of deposits of 1.80% for the third quarter 2025 decreased two basis point and 38 basis points from the linked and prior year quarters, respectively.

•Noninterest income - Noninterest income of $46.6 million for the third quarter 2025 includes the $30.1 million of anticipated insurance proceeds from the pending claim related to the tax credit recapture event during the quarter. Excluding this item, noninterest income decreased $4.1 million and $4.9 million from the linked and prior year quarters, respectively, primarily due to lower tax credit and community development income, and, when compared to the prior year quarter, partially offset by a gain on the guaranteed portion of SBA loans sold during the current quarter. The Company sold $22.2 million of SBA guaranteed loans during the third quarter 2025 for a gain of $1.1 million.

•Noninterest expense - Noninterest expense of $109.8 million for the third quarter 2025 increased $4.1 million and $11.8 million from the linked and prior year quarters, respectively. The increase from the linked and prior year quarters was primarily driven by variable deposit costs and higher loan and legal expenses related to loan workouts and other real estate owned (“OREO”). Compared to the prior year quarter, the increase was also primarily due to higher employee compensation cost.

•Loans - Loans totaled $11.6 billion at September 30, 2025, an increase of $174.3 million, or 6% on an annualized basis, from the linked quarter, and $503.2 million from the prior year quarter. Average loans totaled $11.5 billion, compared to $11.4 billion and $11.0 billion for the linked and prior year quarters, respectively.

•Asset quality - The allowance for credit losses to total loans was 1.29% at September 30, 2025, compared to 1.27% at June 30, 2025 and 1.26% at September 30, 2024. The provision for credit losses in the third quarter 2025 was $8.4 million, compared to $3.5 million and $4.1 million for the linked and prior year quarters, respectively. The ratio of nonperforming assets to total assets was 0.83% at September 30, 2025, compared to 0.71% and 0.22% at June 30, 2025 and September 30, 2024, respectively. During the third quarter 2025, a $12 million life insurance premium loan with adequate collateralization migrated into nonperforming assets. This relationship, along with the previously disclosed Southern California relationship, represents approximately 60% of nonperforming assets at September 30, 2025. The Company has a high certainty of collection for both of these relationships.

•Deposits - Deposits totaled $13.6 billion at September 30, 2025, an increase of $250.6 million and $1.1 billion from the linked and prior year quarters, respectively. Excluding brokered certificates of deposits, deposits increased $240.5 million and $821.0 million from the linked and prior year quarters, respectively. Average deposits were $13.6 billion, $13.2 billion and $12.5 billion for the current, linked and prior year quarters, respectively. At September 30, 2025, noninterest-bearing deposit accounts totaled $4.4 billion, or 32% of total deposits, and the loan to deposit ratio was 85%.

•Capital - Total stockholders’ equity was $2.0 billion and the tangible common equity to tangible assets ratio3 was 9.60% at September 30, 2025, compared to 9.42% at June 30, 2025. Enterprise Bank & Trust remains “well-capitalized,” with a common equity tier 1 ratio of 12.4% and a total risk-based capital ratio of 13.6% at September 30, 2025. The Company’s common equity tier 1 ratio and total risk-based capital ratio were 12.0% and 14.4%, respectively, at September 30, 2025.

The Company’s Board of Directors (the “Board”) approved a quarterly dividend of $0.32 per share of common stock, payable on December 31, 2025 to stockholders of record as of December 15, 2025. 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) September 15, 2025 to (but excluding) December 15, 2025. The dividend will be payable on December 15, 2025 to holders of record of Series A Preferred Stock as of November 28, 2025.

2 Non-taxable income is presented on a fully tax-equivalent basis using a tax rate of approximately 25%. The tax-equivalent adjustments were $3.0 million, $2.7 million, and $2.1 million for each of the three months ended September 30, 2025, June 30, 2025, and September 30, 2024, respectively.

Net interest income of $158.3 million for the third quarter 2025 increased $5.5 million and $14.8 million from the linked and prior year quarters, respectively. Net interest income on a tax equivalent basis was $161.3 million, $155.5 million and $145.6 million for the current, linked and prior year quarters, respectively. The increase from the linked and prior year quarters reflects organic loan growth and continued investment in the securities portfolio, partially offset by an increase in interest-bearing liabilities. Net interest income for the current quarter also benefited by one additional day compared to the linked quarter. On September 2, 2025, the Company called $63.3 million of subordinated debt at a floating rate of three-month Term SOFR plus a spread of 5.66% that was replaced by a $63.3 million single advance term loan. The term loan is payable in quarterly installments on March 31, June 30, September 30 and December 31 with a final installment due on the five year anniversary of the initial advance date. The interest rate on the term loan is one-month Term SOFR plus 2.50%.

Since September 2024, the Federal Reserve has reduced the federal funds target rate 125 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 third quarter 2025 increased $6.4 million primarily due to an increase of $96.0 million in average loan balances, a $204.3 million increase in the average securities balance, and a seven basis point increase in the yield on securities due to new purchases and the reinvestment of cash flows from the runoff of lower yielding investments. The average interest rate of new loan originations in the third quarter 2025 was 6.98%, a decrease of 28 basis points from the linked quarter. Investment purchases in the third quarter 2025 had a weighted average, tax equivalent yield of 4.99%.

Interest expense in the third quarter 2025 increased $0.9 million primarily due to organic growth in interest-bearing deposits, an increase in wholesale borrowings and the higher rate incurred on subordinated debt for two months in the quarter. These increases were partially offset by a decline in the average balance of customer repurchase agreements and a reduction in the cost of interest-bearing deposits due to the Federal Reserve’s reduction in the target federal funds rate. The total cost of deposits, including noninterest-bearing demand accounts, was 1.80% during the third quarter 2025, compared to 1.82% in the linked quarter.

NIM, on a tax equivalent basis, was 4.23% in the third quarter 2025, an increase of two basis points and six basis points from the linked and prior year quarters, respectively. For the month of September 2025, the loan portfolio yield was 6.65% and the cost of total deposits was 1.77%.

1OREO and repossessed assets

Nonperforming assets increased $21.7 million and $102.8 million from the linked and prior year quarters, respectively. The increase in nonperforming assets in the third quarter 2025 was primarily due to three relationships in the C&I and CRE categories of $13.0 million and $2.1 million, respectively. The increase in nonperforming assets from the prior year quarter is primarily related to seven commercial real estate loans totaling $68.4 million to special purpose entities (each an “SPE Borrower”) affiliated with two commercial banking relationships in Southern California that share some common ownership. Litigation resulting from a business dispute between the owners of the entities resulted in all of the SPE Borrowers filing bankruptcy in the first quarter of 2025, which was subsequently dismissed. The SPE Borrowers were again placed in bankruptcy in October 2025. In August 2025, Enterprise Bank & Trust commenced foreclosure proceedings with respect to the real property collateral owned by each SPE Borrower. As a result of Enterprise Bank & Trust’s senior secured first lien collateral position with respect to the real property owned by the SPE Borrowers, the Company expects to collect the full balance of these loans.

The provision for credit losses totaled $8.4 million in the third quarter 2025, compared to $3.5 million and $4.1 million in the linked and prior year quarters, respectively. The provision for credit losses in the third quarter 2025 was primarily related to the increase in nonperforming loans, net charge-offs, loan growth and changes in the economic forecast that influences projected future losses in the allowance calculation. Annualized net charge-offs totaled 14 basis points of average loans in the current and prior year quarters, compared to two basis points in the linked quarter.

Total noninterest income was $46.6 million for the third quarter 2025, an increase of $26.0 million and $25.2 million from the linked and prior year quarters, respectively. The increase from the linked and prior year quarters was primarily driven by the $30.1 million in accrued insurance proceeds that are anticipated to be received as a result of the recaptured tax credits during the quarter, partially offset by lower tax credit income. During the third quarter 2025, a solar provider from which the Company had purchased $24.1 million of transferrable solar tax credits declared bankruptcy. The bankrupt solar provider indirectly owned, through a complex structure of multiple entities, the solar projects generating the tax credits that the Company purchased. As part of the bankruptcy, the bankrupt solar provider sold and transferred equity interests in certain of those entities. As a result of this transfer, the $24.1 million of solar tax credits purchased by the Company were recaptured. The Company previously purchased an insurance policy to insure against recapture risk and anticipates proceeds from the insurance policy to cover the $24.1 million of recaptured tax credits and approximately $6.0 million of incremental tax liability attributable to the anticipated insurance proceeds from the insured recaptured credits. Tax credit income is typically highest in the fourth quarter of each year and will vary in other periods based on transaction volumes and fair value changes on credits carried at fair value.

Total other income$6,771 $8,429 $(1,658)(20)%$8,347 $(1,576)(19)%

The decrease in other income from the linked quarter was primarily due to a decrease of $0.5 million in BOLI income and a decrease of $1.1 million in community development investment income. During the linked quarter, the Company received the payout of a BOLI policy that did not recur in the third quarter 2025. Community development investment income is not a consistent source of income and fluctuates based on distributions from the underlying funds.

In the prior year quarter, the Company realized a net gain of $3.2 million on the sale of OREO that did not recur in the current period. This was partially offset by a gain of $1.1 million in the current quarter on the sale of $22.2 million of guaranteed SBA loans. On a periodic basis, the Company will opportunistically sell SBA guaranteed loans. Loan sales were executed in the current and linked quarters, while no loans were sold in the prior year quarter.

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 increased $2.4 million from the linked quarter primarily due to an increase of $146.0 million in average deposit balances from the linked quarter for businesses eligible for the earnings credit allowance.

9


The increase in noninterest expense of $11.8 million from the prior year quarter was primarily due to an increase in the associate base, merit increases throughout 2024 and 2025, an increase of $3.4 million in deposit costs due to higher earnings credit allowances and deposit vertical average balances, and an increase of $0.6 million in acquisition costs related to the previously announced branch acquisition that closed in the fourth quarter 2025. These increases were partially offset by a decline in core conversion expenses due to the completion of the core implementation in the fourth quarter 2024. For the third quarter 2025, the core efficiency ratio5 was 61.0%, compared to 59.3% for the linked quarter and 58.4% for the prior year quarter.

Income Taxes
The effective tax rate for the third quarter 2025 was 47.8%, compared to 20.0% and 19.4% in the linked and prior year quarters, respectively. Included in tax expense during the current quarter is $24.1 million in transferrable tax credits that were recaptured as discussed above and approximately $6.0 million of incremental tax liability attributable to the anticipated insurance proceeds from the insured recaptured credits. Excluding these items, the adjusted effective tax rate5 for the third quarter 2025 was 20.0%.

Total equity was $2.0 billion at September 30, 2025, an increase of $59.4 million and $150.3 million from the linked and prior year quarters, respectively. Tangible book value per common share5 was $41.58 at September 30, 2025, compared to $40.02 and $37.26 at June 30, 2025 and September 30, 2024, respectively.

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.

5 Core efficiency ratio, tangible common equity to tangible assets, tangible book value per common share, and adjusted effective tax rate are non-GAAP measures. Refer to discussion and reconciliation of these measures in the accompanying financial tables.

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, adjusted effective tax rate, 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, allowance for credit losses to total loans excluding guaranteed loans, adjusted ROAA, adjusted effective tax rate 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, adjusted effective tax rate, 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, allowance for credit losses to total loans excluding guaranteed loans, adjusted ROAA, adjusted effective tax rate 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, core conversion expenses, acquisition costs, accrued insurance proceeds anticipated to be received as a result of recaptured tax credits, and the gain or loss on sale of other real estate owned and 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.
