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, liquidity, yields and returns, loan diversification and credit management, shareholder value creation and the impact of 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. 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, our ability to attract and retain deposits and access to other sources of liquidity, 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, 2022, 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. 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. Readers are cautioned not to place undue reliance on any forward-looking statements. Except to the extent required by applicable law or regulation, EFSC 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

We not only operate in a highly regulated environment and seek to comply with the laws and regulations applicable to our businesses, but we also strive to operate with integrity and accountability consistent with our Guiding Principles. Our commitment to sustainability begins with the Board of Directors of Enterprise. As the governing body responsible for our general oversight and strategic direction, the Board establishes parameters to ensure that our interactions with society and the environment are considered in connection with all business activities. Governance Climate With the oversight of our Board and the Risk Committee, we are formulating processes for identifying, measuring and modeling the impact of climate-related risks and their potential significance to our ongoing business operations and long-term value. Community Involvement We are committed to managing our business and community relationships in ways that positively impact our associates, clients and the diverse communities where we live and work. We have a long-standing history of supporting our communities. Our Community Impact Report is available at enterprisebank.com/ about/corporate-responsibility. Human Capital Several of our Guiding Principles focus on our associates and the communities in which they work and live. We focus on creating an open, diverse and transparent culture that celebrates teamwork and recognizes associates at all levels. Our Results 40
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 return on average assets (“PPNR ROAA”), core efficiency ratio, tangible book value per share, and the tangible common equity ratio, in this presentation 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, core efficiency ratio and the tangible common equity ratio, collectively “core performance measures,” presented in this report 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 include exclude certain other income and expense items, such as merger related expenses, facilities charges, impact of non-core acquired loans which were acquired from the FDIC and previously covered by loss share agreements, 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. 41
