ENTERPRISE FINANCIAL REPORTS THIRD QUARTER 2020 RESULTS

Third Quarter Results

•Net income of $18.0 million, $0.68 per diluted share, including the impact of provision for credit losses of $0.40 per share

•Net interest margin (tax equivalent) of 3.29%

•Return on average assets of 0.86%

•Maintained dividend of $0.18 per share for fourth quarter

•Received Federal Reserve and FDIC approval for announced acquisition of Seacoast Commerce Banc Holdings (“Seacoast”) and Seacoast Commerce Bank

St. Louis, Mo. October 19, 2020 – Enterprise Financial Services Corp (Nasdaq: EFSC) (the “Company” or “EFSC”) reported net income of $18.0 million for the third quarter 2020, an increase of $3.3 million compared to the linked second quarter (“linked quarter”) and a decrease of $11.1 million from the prior year quarter. Earnings per diluted share (“EPS”) was $0.68 for the third quarter 2020, compared to $0.56 and $1.08 for the linked and prior year quarters, respectively. Net income and EPS in the current quarter increased from the linked quarter primarily due to a reduction in provision for credit losses and an increase in noninterest income. This increase was partially offset by $1.6 million of merger-related expenses. The decrease in net income and EPS from the prior year quarter was primarily due to an increase in provision for credit losses.

Jim Lally, EFSC’s President and Chief Executive Officer, commented, “Today we reported earnings of $0.68 per diluted share for the third quarter. These financial results reflect solid performance with pre-provision net revenue¹ of $38.0 million, or 1.81% of average assets. Given the ongoing economic uncertainty, we continued to build our allowance for credit losses, and our earnings profile allowed us to also build capital during the third quarter. As we move into the end of 2020, we remain well positioned to continue to support our customers, complete the acquisition of Seacoast and execute on our business plans.”

Highlights

•Earnings - Net income in the third quarter 2020 was $18.0 million, an increase of $3.3 million compared to the linked quarter and a decrease of $11.1 million from the prior year quarter. EPS was $0.68 per diluted share for the third quarter 2020, compared to $0.56 and $1.08 per diluted share for the linked and prior year quarters, respectively.

•Pre-provision net revenue¹ (“PPNR”) - PPNR (excluding merger-related expenses) of $38.0 million in the third quarter 2020 increased $0.1 million and decreased $0.7 million from the linked and prior year quarters, respectively.

¹ PPNR is a non-GAAP measure. Refer to discussion and reconciliation of these measures in the accompanying financial tables.

•Net interest income and net interest margin (“NIM”) - Net interest income of $63.4 million for the third quarter 2020 decreased $2.5 million and increased $0.3 million, from the linked quarter and prior year quarter, respectively. NIM was 3.29% for the third quarter 2020, compared to 3.53% and 3.81% for the linked quarter and prior year quarter, respectively.

•Noninterest income - Noninterest income of $12.6 million for the third quarter 2020 increased $2.7 million and decreased $0.9 million from the linked quarter and prior year quarter, respectively. The current quarter increase was driven by volume increases in deposit services, card services, mortgage banking and tax credit activity.

•Loans - Total loans declined $13.7 million, or 0.9% on an annualized basis, from the linked quarter to $6.1 billion as of September 30, 2020. Year-over-year, loans grew $898.3 million, or 17.2% on an annualized basis, from $5.2 billion as of September 30, 2019. Average loans totaled $6.1 billion for the quarter ended September 30, 2020 compared to $6.0 billion and $5.2 billion for the linked and prior year quarters, respectively. Paycheck Protection Program (“PPP”) loans primarily contributed to growth in the loan portfolio over the prior year quarter. As of September 30, 2020, loan modifications in a deferral status comprised 2% of the loan portfolio.

* Non-GAAP measures. Refer to discussion and reconciliation of these measures in the accompanying financial tables. Calculations not adjusted for increase in average deposits or increase in deposit expense, as applicable.

•Asset quality - The allowance for credit losses on loans to total loans increased to 2.01% at September 30, 2020 from 1.80% and 0.85% at June 30, 2020 and September 30, 2019, respectively. Nonperforming assets to total assets was 0.53% at September 30, 2020 compared to 0.55% and 0.33% at June 30, 2020 and September 30, 2019, respectively. Improving economic forecasts in the current quarter reduced the provision for credit losses compared to the first and second quarters of this year. This improvement was offset by an increase in qualitative reserves established for certain loan portfolios, including hospitality and loans that have received principal and interest deferrals.

2

•Deposits - Total deposits decreased $23.4 million, or 1.4% on an annualized basis, from the linked quarter to $6.7 billion as of September 30, 2020. Year-over-year, deposits grew $1.1 billion, or 18.7% on an annualized basis, from $5.6 billion as of September 30, 2019. Average deposits totaled $6.7 billion for the quarter ended September 30, 2020 compared to $6.6 billion and $5.6 billion for the linked and prior year quarters, respectively. Deposits attributable to PPP loan fundings primarily contributed to the growth in deposits over the prior year period. Noninterest deposit accounts represented 28.9% of total deposits at September 30, 2020, and the loan to deposit ratio was 91.8% at that date.

•Capital - Total shareholders’ equity was $882.3 million and the tangible common equity to tangible assets ratio was 7.99% at September 30, 2020, compared to 7.81% at June 30, 2020. The Bank’s regulatory capital ratios remain “well-capitalized,” with a common equity tier 1 ratio of 12.0% and a total risk-based capital ratio of 13.3% as of September 30, 2020. The Company’s common equity tier 1 ratio and total risk-based capital ratio was 10.2% and 14.6%, respectively, at September 30, 2020.

The Company suspended its repurchase of shares through the share repurchase plan in March 2020. There are 95,907 shares available for repurchase under the existing authorization.

The Company’s Board of Directors approved a quarterly dividend of $0.18 per common share, payable on December 31, 2020 to shareholders of record as of December 15, 2020.

•Liquidity - The Company maintains a high level of both on-balance-sheet and off-balance-sheet liquidity. At September 30, 2020, on-balance-sheet liquidity consisted of cash and unpledged investment securities of $1.0 billion. Off-balance-sheet liquidity totaled $1.5 billion through the Federal Home Loan Bank, Federal Reserve and correspondent bank lines. The Company also has an unused $25 million revolving line of credit and maintains a shelf registration allowing for the issuance of various forms of equity and debt securities. The $63.3 million subordinated debt issuance in the second quarter 2020 also has enhanced the holding company’s liquidity position.

Net interest income for the third quarter decreased $2.5 million to $63.4 million from $65.8 million in the linked quarter, and increased $0.3 million from the prior year period. NIM, on a tax equivalent basis, was 3.29% for the third quarter, compared to 3.53% in the linked quarter, and 3.81% in the third quarter of 2019. The decrease from the linked quarter was primarily due to slightly lower rates on non-PPP loans plus the impact of the low yield on PPP loans. Additionally, loan yields for non-PPP loans declined in the linked quarter due to both LIBOR resets as well as lower rates on new loans and renewing loans which, combined, impacted yields by 20 basis points.

Core net interest income and core NIM noted in the table below exclude incremental accretion on non-core acquired loans.

² Represents incremental accretion income on non-core acquired loans which were acquired from the FDIC and previously covered by shared-loss agreements.

³ Core net interest income and core NIM are non-GAAP measures. Refer to discussion and reconciliation of these measures in the accompanying financial tables.

NIM decreased 24 basis points from the linked quarter to 3.29% during the current quarter primarily due to a 29 basis point decrease in earning asset yields. The decrease in the earning asset yield was primarily due to a combination of higher average balances on PPP loans (two bps), lower average balances for non-PPP loans (six bps), and an increase in short-term investment balances (five bps), combined with reduced investment (two bps) and loan (14 bps) yields, each as compared to the linked quarter. The full-quarter impact of $63.3 million of subordinated debentures issued during the second quarter negatively impacted NIM by an additional two basis points.

The cost of interest-bearing liabilities was relatively unchanged from the linked quarter. The Company responded to interest rate trends earlier in the year by reducing the cost of certain managed money market and interest-bearing transaction accounts. Increases in the cost of borrowings were offset by lower balances and rates on brokered and other time deposits.

Loans totaled $6.1 billion at September 30, 2020, decreasing $13.7 million, or 0.9% on an annualized basis, compared to the linked quarter. Year-over-year, loans increased $898.3 million, or 17.2% on an annualized basis. The year-over-year increase was primarily due to PPP loans. The largest growth categories, excluding PPP, compared to the linked quarter were C&I, other, and tax credits. New loan originations, excluding PPP, and revolving line advances increased during the quarter from the linked quarter, offset by accelerated loan paydowns. Line draw utilization continues to decline. At September 30, 2020 utilization was 40.1% compared to 40.3% and 49.5% at June 30, 2020 and March 31, 2020, respectively.

The Company has implemented several loan programs to assist its customers impacted by the COVID-19 pandemic. These programs include consumer and business deferral programs and expanded small business lines of credit.

Nonperforming loans decreased $1.9 million to $39.6 million at September 30, 2020 from $41.5 million at June 30, 2020. Activity during the current quarter primarily included additions of $10.5 million, paydowns of $9.7 million, and charge-offs of $2.6 million. The addition of $10.5 million during the quarter was primarily from one $8.7 million hotel loan that went on nonaccrual. Other real estate decreased slightly during the third quarter 2020 due to write-downs and sales of $0.3 million offset by one addition of $0.3 million.

The Company recorded a provision for credit losses of $14.1 million for the third quarter 2020 compared to $19.6 million for the linked quarter and $1.8 million for the prior year quarter. The provision for credit losses in the third quarter 2020 was primarily due an increase in individual reserves and qualitative reserves for certain higher-risk loan portfolios. To the extent that the Company does not recognize charge-offs and economic forecasts improve in future periods, the Company could recognize a reversal of provision for credit losses. Conversely, if economic conditions and the Company’s forecast continue to worsen, the Company could recognize elevated levels of provision for credit losses.

Total noninterest income for third quarter 2020 was $12.6 million, an increase of $2.7 million from the linked quarter and a decrease of $0.9 million from the prior year quarter. The increase from the linked quarter was primarily due to improved transaction volumes for deposit service charges and card services, increased tax credit income and continued growth in mortgage revenue.

Noninterest Expenses

Noninterest expense was $39.5 million for the third quarter 2020, compared to $37.9 million for the linked quarter, and $38.2 million for the third quarter 2019. The increase from the linked quarter and prior year quarter was primarily due to merger-related expenses of $1.6 million.

For the third quarter 2020, the Company’s efficiency ratio was 52.0% compared to 50.0% and 49.9% for the linked quarter and prior year quarter, respectively. The Company’s core efficiency ratio⁴ was 51.0% for the quarter ended September 30, 2020, compared to 50.7% for the linked quarter and 51.7% for the prior year quarter.

⁴ Core efficiency ratio is a non-GAAP measure. Refer to discussion and reconciliation of this measure in the accompanying financial tables.

Income Taxes

The Company’s effective tax rate was 20% for each of the quarters ended September 30, 2020, the linked quarter and prior year quarter.

Capital

The following table presents various EFSC capital ratios:

Percent	September 30, 2020		June 30, 2020		March 31, 2020		December 31, 2019		September 30, 2019
Total risk-based capital to risk-weighted assets	14.6	%	14.4	%	12.9	%	12.9	%	12.7	%
Tier 1 capital to risk weighted assets	11.6	%	11.4	%	11.0	%	11.4	%	11.2	%
Common equity tier 1 capital to risk-weighted assets	10.2	%	9.9	%	9.6	%	9.9	%	9.6	%
Tangible common equity to tangible assets5	8.0	%	7.8	%	8.4	%	8.9	%	8.5	%
5 Tangible common equity to tangible assets is a non-GAAP measure. Refer to discussion and reconciliation of this measure in the accompanying financial tables.

The Company’s strong earnings profile continues to build total capital even with the elevated level of provision for credit losses in 2020. The growth in the balance sheet due to PPP did not negatively impact the Company’s regulatory capital ratios due to the SBA guarantee. The issuance of subordinated debt during the second quarter of 2020 enhanced total risk-based capital. 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 core net interest income, core net interest margin, tangible common equity, core efficiency ratios, ROATCE, PPNR, financial metrics adjusted for PPP impact, and the tangible common equity ratio, 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 core net interest income, core net interest margin, core efficiency ratio, ROATCE, PPNR, financial metrics adjusted for PPP impact, and the tangible common equity ratio, 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 non-core acquired loans, which were acquired from the FDIC and previously covered by shared-loss agreements, and the related income and expenses, the impact of certain non-comparable items, and the Company’s operating performance on an ongoing basis. Core performance measures include contractual interest on non-core acquired loans, but exclude incremental accretion on these loans. Core performance measures also exclude expenses directly related to non-core acquired loans. Core performance measures also exclude certain other income and expense items, such as merger related expenses, facilities charges, and the gain or loss on sale of investment securities, 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-

9

GAAP financial measures and ratios, or a reconciliation of the non-GAAP calculation of the financial measures for the periods indicated.

Forward-Looking Statements Some of the information in this report may contain “forward-looking statements” within the meaning of and intended to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements may include projections based on management’s current expectations and beliefs concerning future developments and their potential effects on the Company including, without limitation, plans, strategies and goals, and statements about the Company’s expectations regarding revenue and asset growth, financial performance and profitability, loan and deposit growth, yields and returns, loan diversification and credit management, shareholder value creation and the impact of the Company's pending acquisition of Seacoast Commerce Banc Holdings ("Seacoast") and other acquisitions. Forward-looking statements include, but are not limited to, statements about the Company’s plans, expectations, and projections of future financial and operating results, as well as statements regarding the Company’s plans, objectives, expectations or consequences of announced transactions. The Company uses words such as “may,” “might,” “will,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “could,” “continue,” and “intend”, and variations of such words and similar expressions, in this release to identify such forward-looking statements. Forward-looking statements are inherently subject to risks and uncertainties that could cause actual results to differ materially from those contemplated from such statements. The COVID-19 pandemic is adversely affecting us, our customers, counterparties, employees, and third-party service providers, and the ultimate extent of the impacts on our business, financial position, results of operations, liquidity, and prospects is uncertain. Continued deterioration in general business and economic conditions, including further increases in unemployment rates, or turbulence in domestic or global financial markets could adversely affect our revenues and the values of our assets and liabilities, reduce the availability of funding, lead to a tightening of credit, and further increase stock price volatility. In addition, changes to statutes, regulations, or regulatory policies or practices as a result of, or in response to COVID-19, could affect us in substantial and unpredictable ways.  Other factors that could cause or contribute to such differences include, but are not limited to, the Company’s ability to efficiently integrate acquisitions, including the Seacoast 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 conditions, 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 regulatory requirements, changes in accounting policies and practices or accounting standards, including ASU 2016-13 (Topic 326), “Measurement of Credit Losses on Financial Instruments,” commonly referenced as the Current Expected Credit Loss (“CECL”) model, which changed how we estimate credit losses and may increase the required level of our allowance for credit losses after adoption on January 1, 2020, uncertainty regarding the future of LIBOR, natural disasters, war or terrorist activities, or pandemics, or the outbreak of COVID-19 or similar outbreaks, and their effects on economic and business environments in which we operate, as well as other risk factors described in the Company’s 2019 Annual Report on Form 10-K and other reports filed with the Securities and Exchange Commission (the “SEC”). Forward-looking statements speak only as of the date they are made, and the Company undertakes no obligation to update them in light of new information or future events unless required under the federal securities laws. 2

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 adjusted EPS, core net interest income, core net interest margin, tangible common equity, core efficiency ratios, ROATCE, adjusted ROAA, adjusted ROAE, and adjusted ROATCE, and the tangible common equity ratio, 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 adjusted EPS, core net interest income, core net interest margin, core efficiency ratio, adjusted ROAA, adjusted ROAE, ROATCE, adjusted ROATCE, and the tangible common equity ratio, 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 non-core acquired loans, which were acquired from the FDIC and previously covered by loss share agreements, and the related income and expenses, the impact of certain non-comparable items, and the Company’s operating performance on an ongoing basis. Core performance measures include contractual interest on non-core acquired loans, but exclude incremental accretion on these loans. Core performance measures also exclude expenses directly related to non-core acquired loans. Core performance measures also exclude certain other income and expense items, such as merger related expenses, facilities charges, and the gain or loss on sale of investment securities, 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.
