Enterprise Financial Services Corp Third Quarter 2021 Investor Presentation Exhibit 99.1

Forward-Looking Statements Certain statements contained in this presentation may be considered “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 regarding Enterprise Financial Services Corp (the “Company,” “EFSC,” or “Enterprise”), including its wholly-owned subsidiary Enterprise Bank & Trust (“EB&T”). 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, statements about the Company’s plans, strategies, goals, objectives, expectations, or consequences of statements about the future performance, operations, products and services of the Company and its subsidiaries, as well as 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, products and services, shareholder value creation and the impact of the Company’s acquisitions. Forward-looking statements are typically identified by words such as “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “pro forma” and other similar words and expressions. Forward-looking statements are subject to numerous assumptions, risks and uncertainties, which change over time. Forward-looking statements speak only as of the date they are made. Because forward-looking statements are subject to assumptions and uncertainties, actual results or future events could differ, possibly materially, from those anticipated in the forward-looking statements and future results could differ materially from historical performance. 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 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 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, 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, and those factors and risks referenced from time to time in EFSC’s filings with the SEC, including in the Company's Annual Reports on Form 10-K for the fiscal year ended December 31, 2020, and the Company's other filings with the SEC. For any forward-looking statements made in this press release or in any documents, EFSC claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Annualized, pro forma, projected and estimated numbers in this document are used for illustrative purposes only, are not forecasts and may not reflect actual results. Except to the extent required by applicable law or regulation, Enterprise disclaims any obligation to revise or publicly release any revision or update to any of the forward-looking statements included herein to reflect events or circumstances that occur after the date on which such statements were made. 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 tangible common equity, ROATCE, PPNR, PPNR ROAA, 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 tangible common equity, ROATCE, PPNR, PPNR ROAA, 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 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. 35
