St. Louis, Mo. January 23, 2023 – Jim Lally, President and Chief Executive Officer of Enterprise Financial Services Corp (Nasdaq: EFSC) (the “Company” or “EFSC”), commented, “We finished 2022 with strong financial results in the fourth quarter and the full year. Our performance is a result of our commitment to building partnerships with our clients, the execution of our strategic initiatives and our diversified business platform. We reported earnings per share (“EPS”) of $1.58 for the fourth quarter and $5.31 for 2022, both of which are records for the Company. We also achieved loan growth of 16% and 8% for the fourth quarter, annualized, and full year, respectively. Our record earnings in the fourth quarter resulted in a 1.83% return on average assets and a 22.62% return on average tangible common equity.1 For the full year, we had a 1.52% return on average assets and a 19.10% return on average tangible common equity.1 As we look to 2023, we are excited for the opportunity to continue the strong momentum we built during 2022.”

Full-Year Highlights

Please note comparisons to the prior year are impacted by the acquisition of First Choice Bancorp (“First Choice” or “FCBP”) in the third quarter of 2021.

For 2022, net income was $203.0 million, or $5.31 per diluted share, compared to $133.1 million, or $3.86 per diluted share, in 2021. Pre-provision net revenue (“PPNR”)2 for 2022 was $258.8 million, compared to $207.5 million in 2021. Organic earning-asset growth and expansion of net interest margin due to the increase in market interest rates were the primary contributors to the PPNR increase in 2022. Additionally, 2022 included the first full year of operations from the FCBP acquisition.

The Company’s asset sensitive balance sheet benefited from the increase in market interest rates during 2022. Net interest margin (“NIM”) expanded to 3.89% in 2022, from 3.41% in 2021. The increase in NIM and average interest-earning asset growth of $1.7 billion resulted in total net interest income of $473.9 million in 2022, a 32% increase from $360.2 million in 2021.

Noninterest income was $59.2 million, a decrease of 13% from $67.7 million in 2021. While the increase in interest rates benefited net interest income, higher interest rates resulted in lower mortgage banking and tax credit income. The Company also became subject to the Durbin Amendment limitation on interchange income in 2022, which reduced card services revenue. Total noninterest expense was $274.2 million in 2022, a 12% increase from $245.9 million in 2021. However, the core efficiency ratio3 remained stable at 49.8% in 2022, compared to 49.5% in 2021.

Credit quality remained favorable, with nonperforming assets declining to 0.08% of total assets, from 0.23% at the end of 2021. Net charge-offs were 0.04% of average loans in 2022, compared to 0.14% in 2021. The improvements in credit quality resulted in the allowance for credit losses declining to 1.41% of total loans at the end of 2022, from 1.61% at the end of 2021. Excluding guaranteed portions of loans, which includes Paycheck Protection Program (“PPP”) loans, the allowance to loans ratio was 1.56% and 1.84% at the end of 2022 and 2021, respectively. The allowance for credit losses to nonperforming loans increased year-over-year as nonperforming loans declined $18.0 million, or 64%, from the prior year. A provision benefit of $0.6 million was recorded in 2022, compared to a provision expense of $13.4 million in 2021.

The Company maintained a strong liquidity position in 2022, with total deposits of $10.8 billion, a loan-to-deposit ratio of 89.9% and cash and investment securities of $2.6 billion. This compares to total deposits of $11.3 billion, a loan-to-deposit ratio of 79.5% and cash and investment securities of $3.9 billion in 2021. Total deposits include a significant non-interest bearing deposit portfolio that comprises 42.9% of total deposits at December 31, 2022.

Total shareholders’ equity was $1.5 billion at the end of both 2022 and 2021. Net income of $203.0 million was partially offset by a decline in the fair value of available for sale investment securities of $149.8 million from the increase in market interest rates. In addition, the Company returned $66.5 million to common shareholders through dividends of $33.6 million, or $0.90 per share, and share repurchases of $32.9 million in 2022.

Fourth Quarter Highlights

•Earnings - Net income in the fourth quarter 2022 was $60.0 million, an increase of $9.8 million compared to the linked quarter and an increase of $9.2 million from the prior year quarter. EPS was $1.58 per diluted common share for the fourth quarter 2022, compared to $1.32 and $1.33 per diluted common share for the linked and prior year quarters, respectively.

•PPNR - PPNR2 of $78.6 million in the fourth quarter 2022 increased $13.7 million and $15.2 million from the linked and prior year quarters, respectively. The increase from both the linked and prior year quarters was primarily due to an increase in operating revenue, partially offset by an increase in noninterest expense.

•Net interest income and NIM - Net interest income of $138.8 million for the fourth quarter 2022 increased $14.5 million and $36.8 million from the linked and prior year quarters, respectively. NIM was 4.66% for the fourth quarter 2022, compared to 4.10% and 3.32% for the linked and prior year quarters, respectively. Net interest income and NIM benefited from higher average loan and investment balances and expanding yields on earning assets, partially offset by higher deposit costs and a decline in average interest-earning cash.

•Noninterest income - Noninterest income of $16.9 million for the fourth quarter 2022 increased $7.4 million from the linked quarter and declined $5.8 million from the prior year quarter. The increase from the

2

linked quarter was primarily due to an increase in tax credit income and fees earned on community development investments. Tax credit income in the linked quarter was lower due to the impact from the increase in certain market interest rates on tax credit projects carried at fair value. The decrease in noninterest income from the prior year quarter was primarily due to lower fees from community development investments, tax credit income and card services revenue.

•Loans - Total loans increased $382.2 million from the linked quarter to $9.7 billion as of December 31, 2022. Loans grew 16.5%, on an annualized basis, from the linked quarter and 11.3% for the year when excluding PPP loan balances. Average loans totaled $9.4 billion for the fourth quarter 2022, compared to $9.2 billion and $9.0 billion for the linked and prior year quarters, respectively.

•Asset quality - The allowance for credit losses to loans was 1.41% at December 31, 2022, compared to 1.50% at September 30, 2022 and 1.61% at December 31, 2021. Nonperforming assets to total assets was 0.08% at December 31, 2022, compared to 0.14% and 0.23% at September 30, 2022 and December 31, 2021, respectively. A provision for credit losses of $2.1 million and $0.7 million was recorded in the fourth quarter 2022 and the linked quarter, respectively. A provision benefit of $3.7 million was recorded in the prior year quarter.

•Deposits - Total deposits decreased $228.4 million from $11.1 billion as of the linked quarter to $10.8 billion as of December 31, 2022. The Company has actively managed its deposit rates to remain competitive and to support deposit retention. This has been accomplished while maintaining a relatively low increase in deposit yields compared to the overall increase in market interest rates. The decline in deposits from the linked quarter and the end of the prior year was due primarily to the managed run-off of certain interest-rate sensitive, large balance accounts and reflects a shift in our deposit mix aligned with our disciplined focus on relationship-based, lower-cost deposits. These customers were single service customers and were not part of broader banking relationships. Additionally, certain large deposit outflows experienced in the year were related to customer business transactions. Average deposits totaled $11.0 billion for the fourth quarter 2022, compared to $11.2 billion for both the linked and prior year quarters. At December 31, 2022, noninterest-bearing deposit accounts represented 42.9% of total deposits, and the loan to deposit ratio was 89.9%.

•Capital - Total shareholders’ equity was $1.5 billion and the tangible common equity to tangible assets ratio1 was 8.4% at December 31, 2022, compared to 7.9% at September 30, 2022. Enterprise Bank & Trust remains “well-capitalized,” with a common equity tier 1 ratio of 12.1% and a total risk-based capital ratio of 13.1% as of December 31, 2022. The Company’s common equity tier 1 ratio and total risk-based capital ratio was 11.1% and 14.2%, respectively, at December 31, 2022.

The Company’s Board of Directors approved a quarterly dividend of $0.25 per common share, payable on March 31, 2023 to shareholders of record as of March 15, 2023, an increase of $0.01, or 4%, compared to the fourth quarter 2022. The Board of Directors 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) December 15, 2022 to (but excluding) March 15, 2023. The dividend will be payable on March 15, 2023 to shareholders of record on February 28, 2023.

Net interest income for the fourth quarter was $138.8 million, an increase of $14.5 million from the linked quarter and an increase of $36.8 million from the prior year period. Interest income increased during the quarter due to an increase in certain market interest rates combined with organic loan growth, driving the 11.7% increase in net interest income over the linked quarter. The effective federal funds rate for the fourth quarter 2022 was 3.65%, an increase of 145 basis points, compared to the linked quarter, and a 357 basis point increase over the prior year quarter. Average total loans increased $193.2 million, or 8.3% on an annualized basis, from the linked quarter. The increase in loan interest income was partially offset by higher interest expense on the deposit portfolio, which also reflects an increase in interest rates.

The earning asset yield was 5.25% in the fourth quarter 2022, an increase of 78 basis points compared to the linked quarter. The average loan yield was 5.87% in the fourth quarter 2022, an increase of 77 basis points from the linked quarter. The average loan yield increased due to the repricing of variable-rate loans and the origination of new loans at an average rate of 6.64%. Approximately 17% of the variable-rate loan portfolio reprices on the first day of each quarter and thus, interest income in the period did not benefit from the current quarter’s rate movement. These loans will reset early in the first quarter of 2023.

The average investment yield was 2.91%, an increase of 26 basis points from the linked quarter, while the average investment balance remained relatively stable. The investment yield increased due to the purchase of new investments at higher yields. Investments purchased in the fourth quarter 2022 had a tax equivalent average yield of 5.14%. The yield on interest earning cash deposits was 3.35%, an increase of 118 basis points from the linked quarter, while the average balance declined $398.2 million from the linked quarter to $367.1 million in the fourth quarter 2022.

The interest-bearing liability yield was 1.07% in the fourth quarter 2022, an increase of 40 basis points compared to the linked quarter. The average cost of interest-bearing deposits was 0.94% in the fourth quarter 2022, an increase of 40 basis points over the linked quarter. The increase was primarily due to higher rates paid on money market accounts, which increased 54 basis points to 1.40% in the fourth quarter 2022, and interest bearing demand deposits that increased 42 basis points to 0.73% in the current quarter. The total cost of deposits, including noninterest-bearing demand accounts, was 53 basis points during the fourth quarter 2022.

NIM, on a tax equivalent basis, was 4.66% in the fourth quarter 2022, an increase of 56 basis points from the linked quarter and an increase of 134 basis points from the prior year quarter, as changing interest rates had a greater impact on assets with variable interest rates than on deposit costs. The pace of deposit rate increases has continued to lag the increase in loan rates, resulting in a positive impact on our NIM.

*Specialty loan category

Loans totaled $9.7 billion at December 31, 2022, increasing $382.2 million, compared to the linked quarter. Excluding PPP loans, loans grew $388.0 million, or 16.5% on an annualized basis, from the linked quarter. The increase was driven primarily by C&I and CRE loans with an increase of $124.0 million and $110.6 million, respectively. The specialty lending areas also increased, specifically in tax credits, SBA, and life insurance premium finance, partially offset by a small decline in sponsor finance. Average line utilization was approximately 41% for the quarter ended December 31, 2022, compared to 43% and 40% 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:

	Quarter ended
($ in thousands)	December 31, 2022			September 30, 2022			June 30, 2022			March 31, 2022			December 31, 2021

Nonperforming assets to total assets	0.08		%	0.14		%	0.16		%	0.17		%	0.23		%
Allowance for credit losses to loans	1.41		%	1.50		%	1.52		%	1.54		%	1.61		%
Net charge-offs (recoveries)	$	2,075		$	478		$	(175)		$	1,521		$	3,263
*Guaranteed balances excluded	$	6,708		$	6,532		$	6,063		$	3,954		$	6,481

Nonperforming assets declined $8.2 million during the fourth quarter 2022 and $21.3 million from the prior year quarter. Net charge-offs to average loans were nine basis points in the fourth quarter 2022, compared to two basis

6

points in the linked quarter and 14 basis points in the prior year quarter. The Company recorded a provision for credit losses of $2.1 million in the fourth quarter 2022, compared to a provision for credit losses of $0.7 million in the linked quarter and a provision benefit of $3.7 million in the prior year quarter when economic forecasts were improving. The provision for credit losses in the fourth quarter primarily relates to growth in loans and unfunded commitments and a modest deterioration of economic forecasts, partially offset by an overall improvement in credit quality.

The allowance for credit losses to loans was 1.41% at December 31, 2022, a decrease of nine basis points from the linked quarter. The decline in nonperforming loans and a related decrease in specific loan reserves, along with a shift in the composition of the loan portfolio to categories with lower reserve levels, drove the decline in the ratio of allowance for credit losses to loans. This decline was partially offset by a modest decline in economic forecasts. Loan growth in the quarter was primarily in commercial real estate and C&I loans that generally have a lower reserve level. The ratio of allowance for credit losses to nonperforming loans increased in the current quarter as nonperforming loans declined $8.2 million and $18.0 million from the linked and prior year quarter, respectively.

Deposits

Total cost of deposits	0.53		%	0.31		%	0.13		%	0.10		%	0.10		%

Total deposits at December 31, 2022 were $10.8 billion, a decrease of $228.4 million from September 30, 2022, and a decrease of $514.6 million from December 31, 2021. Deposits declined from the end of the prior year due primarily to the managed run-off of certain interest-rate sensitive, large balance accounts and reflects a shift in the deposit mix aligned with the Company’s disciplined focus on relationship-based, lower-cost deposits.

Total noninterest income for the fourth quarter 2022 was $16.9 million, an increase of $7.4 million from the linked quarter and a decrease of $5.8 million from the prior year quarter. The increase from the linked quarter was primarily due to an increase in tax credit income and fees earned on community development investments (included in Other income). Tax credit income in the current quarter was higher as market interest rates did not negatively impact tax credits held at fair value and tax credit sales reflected seasonal activity. Conversely, an increase in certain interest rates in the third quarter 2022 increased the discount rate used in the fair value of these projects, resulting in a lower fair value. The decrease in noninterest income from the prior year quarter was primarily due to lower fees from community development investments, lower tax credit income, and lower card services revenue. The Durbin Amendment limits the amount of interchange income the Company can earn on debit card transactions. This limitation went into effect for the Company in the third quarter 2022 and reduced card services revenue.

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 is primarily earned from servicing SBA loans and may fluctuate based on prepayment experience and changes to the discount rate used in the valuation of the servicing rights. Mortgage banking revenue has declined since the prior year quarter due to higher interest rates, which have reduced sales volume.

Noninterest expense was $77.1 million for the fourth quarter 2022, compared to $68.8 million for the linked quarter, and $63.7 million for the prior year quarter. Employee compensation and benefits increased $1.2 million from the linked quarter primarily due to higher performance-based incentive accruals, resulting from fourth quarter growth and continued overall improvement in the Company’s financial performance. Deposit costs increased $5.6 million and $8.5 million from the linked and prior year quarters, respectively, primarily due to variable deposit costs in certain of the Company’s specialized deposit businesses that are impacted by higher interest rates, as well as increasing average balances. The increase in noninterest expense of $13.5 million from the prior year quarter was primarily due to an $8.5 million increase in deposit costs that are higher due to growth in specialized deposits and the increase in market interest rates; a $4.7 million increase in employee compensation from merit increases throughout 2021 and 2022 and growth in the associate base; and generally higher operating expenses due to an expanded business platform (e.g. first full year for First Choice). These increases were partially offset by a reduction of $2.3 million in merger costs from the First Choice acquisition recognized in the prior year quarter.

For the fourth quarter 2022, the Company’s efficiency ratio was 49.6%, compared to 51.5% and 51.1% for the linked quarter and prior year quarter, respectively. The Company’s core efficiency ratio3 was 48.1% for the quarter ended December 31, 2022, compared to 49.8% for the linked quarter and 47.5% for the prior year quarter.

3 Core efficiency ratio is a non-GAAP measure. Please refer to discussion and reconciliation of this measure in the accompanying financial tables.

Income Taxes

The Company’s effective tax rate was 22% for both the quarter ended December 31, 2022 and September 30, 2022, compared to 21% for the prior year quarter.

Capital

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

*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 $1.5 billion at December 31, 2022, an increase of $76.0 million from the linked quarter. The increase from the linked quarter was primarily due to the current quarter’s net income of $60.0 million and a $22.9 million increase in accumulated other comprehensive income. The increase in accumulated other comprehensive income was due to a net fair value increase in the Company’s fixed-rate, available-for-sale investment portfolio from changes in market interest rates during the period, partially offsetting the unrealized losses recognized earlier in 2022. Offsetting these increases were $9.9 million in common and preferred dividends. The Company’s tangible common book value per share increased 7.7% in the current quarter to $28.67 at December 31, 2022, compared to $26.62 and $28.28 in the linked and prior year quarters, respectively. The Company’s regulatory capital ratios continue to exceed the “well-capitalized” regulatory benchmark.

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, financial metrics adjusted for PPP

impact, core efficiency ratio, the tangible common equity ratio, and tangible book value 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, financial metrics adjusted for PPP impact, core efficiency ratio, the tangible common equity ratio, and tangible book value 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 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.

They are neither statements of historical fact nor guarantees or assurances of future performance. While there is no assurance that any list of risks and uncertainties or risk factors is complete, important factors that could cause actual results to differ materially from those in the forward-looking statements include the following, without limitation: the Company’s ability to efficiently integrate acquisitions, including the First Choice acquisition, into its operations, retain the customers of these businesses and grow the acquired operations, as well as credit risk, changes in the appraised valuation of real estate securing impaired loans, outcomes of litigation and other contingencies, exposure to general and local economic and market conditions, high unemployment rates, higher inflation and its impacts (including U.S. federal government measures to address higher inflation), U.S. fiscal debt, budget and tax matters, and any slowdown in global economic growth, risks associated with rapid increases or decreases in prevailing interest rates, consolidation in the banking industry, competition from banks and other financial institutions, the Company’s ability to attract and retain relationship officers and other key personnel, burdens imposed by federal and state regulation, changes in legislative or regulatory requirements, as well as current, pending or future legislation or regulation that could have a negative effect on our revenue and businesses, including rules and regulations relating to bank products and financial services, changes in accounting policies and practices or accounting standards, changes in the method of determining LIBOR and the phase out of LIBOR, natural disasters, terrorist activities, war and geopolitical matters (including the war in Ukraine and the imposition of additional sanctions and export controls in connection therewith), or pandemics, including the COVID-19 pandemic, and their effects on economic and business environments in which we operate, including the ongoing disruption to the financial market and other economic activity caused by the continuing COVID-19 pandemic, and those factors and risks referenced from time to time in the Company’s filings with the Securities and Exchange Commission (the “SEC”), including in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, and the Company’s other filings with the SEC. The Company cautions that the preceding list is not exhaustive of all possible risk factors and other factors could also adversely affect the Company’s results.
