St. Louis, Mo. October 23, 2023 – Jim Lally, President and Chief Executive Officer of Enterprise Financial Services Corp (Nasdaq: EFSC) (the “Company” or “EFSC”), said today upon the release of EFSC’s third quarter earnings, “We had strong third quarter operating results with earnings per share of $1.17, a net interest margin of 4.33%, and a return on average assets of 1.26%. In a challenging environment, we continued to expand net interest income while strengthening liquidity and increasing our customer base.

•Noninterest income - Noninterest income of $12.1 million for the third quarter 2023 decreased $2.2 million and increased $2.6 million from the linked and prior year quarters, respectively.

1 Average balances include nonaccrual loans. Interest income includes loan fees of $3.3 million, $3.7 million, and $3.6 million for the three months ended September 30, 2023, June 30, 2023, and September 30, 2022, respectively.
2 Non-taxable income is presented on a fully tax-equivalent basis using a 25.2% tax rate. The tax-equivalent adjustments were $2.1 million, $2.1 million, and $1.9 million for the three months ended September 30, 2023, June 30, 2023, and September 30, 2022, respectively.

Net interest income for the third quarter 2023 was $141.6 million, an increase of $0.9 million, compared to the linked quarter and an increase of $17.3 million from the prior year quarter. Net interest income on a tax equivalent basis was $143.7 million, $142.8 million and $126.1 million for the current, linked and prior year quarters, respectively. The increase from the linked and prior year quarters reflects the benefit of higher market interest rates on the Company’s asset sensitive balance sheet combined with organic growth.
3

Interest income increased $13.0 million during the third quarter 2023 primarily due to an increase of $10.1 million in loan interest income and a $2.4 million increase in interest on cash accounts. Loan interest income has increased from continued loan growth and higher loan yields. Interest on loans benefited from a 16 basis point increase in yield and a $237.1 million increase in average loan balances, compared to the linked quarter. The average interest rate of new loan originations in the third quarter 2023 was 7.89%. Interest on cash accounts increased due to a 49 basis point increase in yield and a $162.0 million increase in average balances.
Interest expense increased $12.1 million in the third quarter 2023 primarily due to a $14.0 million increase in deposit interest expense. This increase was partially offset by a $1.1 million decrease in interest expense on other borrowings. The increase in deposit interest expense reflects a shift in the deposit mix from demand deposits to interest-bearing deposits, particularly money market accounts and certificates of deposit, as well as higher rates paid on deposits. The average cost of interest-bearing deposits was 2.77%, an increase of 51 basis points compared to the linked quarter. The increase in cost was primarily due to higher interest rates paid on commercial balances. The total cost of deposits, including noninterest-bearing demand accounts, was 1.84% during the third quarter 2023, compared to 1.46% in the linked quarter. The decrease in interest expense on other borrowings was primarily due to a decline in average borrowings that were reduced due to the increase in liquidity from the growth in core deposits.
NIM, on a tax equivalent basis, was 4.33% in the third quarter 2023, a decrease of 16 basis points from the linked quarter and an increase of 23 basis points from the prior year quarter. For the month of September 2023, the loan portfolio yield was 6.89% and the cost of total deposits was 2.0%.

Investment securities totaled $2.2 billion at September 30, 2023, a decrease of $56.6 million from the linked quarter. The decrease was primarily due to a $55.2 million decline in the fair value of available-for-sale securities due to a decline in longer-term rates in the quarter. Investment purchases in the third quarter 2023 had a weighted average, tax equivalent yield of 5.60%.
The average duration of the investment portfolio was 5.6 years at September 30, 2023. The Company utilizes the investment portfolio to lengthen the overall duration of the balance sheet. The expected cash flow from pay downs, maturities and interest over the next 12 months is approximately $270 million. The tangible common equity to tangible assets ratio adjusted for unrealized losses on held-to-maturity securities 4 was 7.91% at September 30, 2023, compared to 8.25% at June 30, 2023.

Nonperforming assets increased $39.8 million during the third quarter 2023 and increased $37.4 million from the prior year quarter. Nonperforming loans increased $32.8 million and $30.7 million from the linked and prior year quarters, respectively. OREO and repossessed assets increased $6.9 million and $6.7 million from the linked and prior year quarters, respectively. The increase in nonperforming loans in the third quarter 2023 was primarily due to three relationships in the C&I and CRE categories of $1.8 million and $31.0 million, respectively.

$4.7 million in the current period. Annualized net charge-offs totaled 26 basis points of average loans in the third quarter 2023, compared to 12 basis points and two basis points in the linked and prior year quarters, respectively.
The provision for credit losses totaled $8.0 million in the third quarter 2023, compared to $6.3 million and $0.7 million in the linked and prior year quarters, respectively. The provision for credit losses in the third quarter 2023 was primarily related to net charge-offs, an increase in nonperforming loans, and loan growth, partially offset by an improvement in forecasted economic factors. The allowance for credit losses to total loans was 1.34% at both September 30, and June 30, 2023 compared to 1.50% in the prior year quarter.

Total costs of deposits | 1.84 | % |  | 1.46 | % |  | 0.92 | % |  | 0.53 | % |  | 0.31 | %

Total deposits at September 30, 2023 were $11.9 billion, an increase of $290.0 million and $852.3 million from the linked and prior year quarters, respectively. Excluding brokered certificates of deposits, deposits increased $488.0 million and $285.8 million, from the linked and prior year quarters, respectively. The mix of the deposit portfolio continued the shift from noninterest bearing demand deposits to higher cost categories that began in the first quarter 2023. Competitive pricing pressures and the Federal Reserve’s monetary policy actions have continued to pressure industry-wide deposit flows. Reciprocal deposits, which are placed through third party programs to provide FDIC insurance on larger deposit relationships, totaled $1.1 billion at September 30, 2023, compared to $926.6 million at June 30, 2023.
Total estimated insured deposits, which includes collateralized deposits, reciprocal accounts and accounts that qualify for pass-through insurance, totaled $8.5 billion, or 71% of total deposits, at the end of September 30, 2023, compared to $8.3 billion, or 72% of total deposits, in the linked quarter.
Noninterest Income
The following table presents a comparative summary of the major components of noninterest income for the periods indicated:

| Linked quarter comparison |  | Prior year comparison
| Quarter ended |  | Quarter ended
($ in thousands) | September 30, 2023 |  | June 30, 2023 |  | Increase (decrease) |  | September 30, 2022 |  | Increase (decrease)

Total noninterest income was $12.1 million for the third quarter 2023, a decrease of $2.2 million from the linked quarter and an increase of $2.6 million from the prior year quarter. The decrease from the linked quarter was primarily due to a decrease in tax credit income. 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. The discount rate used in the fair value determination is the 10-year SOFR swap rate, which increased 70 basis points in the third quarter. The increase from the prior year quarter was primarily due to Other income, as further discussed below.
The following table presents a comparative summary of the major components of other income for the periods indicated:

| Linked quarter comparison |  | Prior year comparison
| Quarter ended |  | Quarter ended
($ in thousands) | September 30, 2023 |  | June 30, 2023 |  | Increase (decrease) |  | September 30, 2022 |  | Increase (decrease)

NM - Not meaningful

Community development and private equity distributions included in other income are not consistent sources of income and fluctuate based on distributions from the underlying funds. Servicing fee income may also fluctuate based on prepayment experience and changes to the discount rate used in the valuation of the servicing rights. Swap fee income is generated from customer hedging activities and varies based on customer transaction volume. The decrease in community development income of $1.7 million compared to the linked quarter was partially offset by a $1.5 million gain on the sale of SBA loans in the third quarter 2023. The $2.4 million increase in Other income from the prior year quarter was primarily due to the gain on sale of SBA loans.
Noninterest Expense
The following table presents a comparative summary of the major components of noninterest expense for the periods indicated:

| Linked quarter comparison |  | Prior year comparison
| Quarter ended |  | Quarter ended
($ in thousands) | September 30, 2023 |  | June 30, 2023 |  | Increase (decrease) |  | September 30, 2022 |  | Increase (decrease)
Employee compensation and benefits | $ | 40,771 |  |  | $ | 41,641 |  |  | $ | (870) |  |  | (2) | % |  | $ | 36,999 |  |  | $ | 3,772 |  |  | 10 | %

Deposit costs | 20,987 |  |  | 16,980 |  |  | 4,007 |  |  | 24 | % |  | 7,661 |  |  | 13,326 |  |  | 174 | %
Other expense | 22,688 |  |  | 23,381 |  |  | (693) |  |  | (3) | % |  | 19,686 |  |  | 3,002 |  |  | 15 | %
Total noninterest expense | $ | 88,644 |  |  | $ | 85,956 |  |  | $ | 2,688 |  |  | 3 | % |  | $ | 68,843 |  |  | $ | 19,801 |  |  | 29 | %

Employee compensation and benefits decreased $0.9 million from the linked quarter due to a decrease in benefit costs, primarily due to lower claims on self-insured medical policies. Deposit costs relate to certain specialized
7

deposit businesses that are impacted by higher interest rates as well as increasing average balances. Deposit costs increased $4.0 million from the linked quarter primarily due to higher average balances and an increase in expenses related to the earnings credit earned on these accounts.
The increase in noninterest expense of $19.8 million from the prior year quarter was primarily an increase in the associate base, merit increases throughout 2022 and 2023, and an increase in variable deposit costs.
For the third quarter 2023, the Company’s core efficiency ratio 5 was 56.2%, compared to 54.0% for the linked quarter and 49.8% for the prior year quarter.
Income Taxes
The Company’s effective tax rate was 22% for each of the current, linked and prior year quarters.
Capital
The following table presents total equity and various EFSC capital ratios for the most recent five quarters:

Tangible common equity to tangible assets | 8.51 | % |  | 8.65 | % |  | 8.81 | % |  | 8.43 | % |  | 7.86 | %

*Capital ratios for the current quarter are preliminary and subject to, among other things, completion and filing of the Company’s regulatory reports and ongoing regulatory review.
Total equity was $1.6 billion at September 30, 2023, a decrease of $6.4 million from the linked quarter. The decrease was primarily due to a $44.4 million decrease in accumulated other comprehensive income, primarily due to a net fair value decrease in the Company’s fixed-rate, available-for-sale investment portfolio, and common and preferred stock dividends of $10.3 million. The decrease was partially offset by current period net income of $44.7 million. The Company’s tangible common book value per share was $31.06 at September 30, 2023, compared to $31.23 and $26.62 in the linked and prior year quarters, 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.
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, PPNR return on average assets (“PPNR ROAA”), core efficiency ratio, the tangible common equity ratio, and tangible book value per common 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.
5 Core efficiency ratio is a non-GAAP measure. Refer to discussion and reconciliation of this measure in the accompanying financial tables.

The Company considers its tangible common equity, PPNR, ROATCE, PPNR ROAA, core efficiency ratio, the tangible common equity ratio, and tangible book value per common 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 merger-related expenses, facilities charges, and the gain or loss on sale 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 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.
