Forward-looking statements, including those relating to our beliefs, plans, objectives, goals, expectations, anticipations, estimates and intentions, involve known and unknown risks, uncertainties and other factors, which may be beyond our control, and which may cause the Company’s actual results, performance, achievements, or financial condition to be materially different from future results, performance, achievements, or financial condition expressed or implied by such forward-looking statements. You should not rely on any forward-looking statements as predictions of future events. You should not expect us to update any forward-looking statements, except as required by law. All written or oral forward-looking statements attributable to us are expressly qualified in their entirety by this cautionary notice, together with those risks and uncertainties described in “Risk factors” in our annual report on Form 10-K for the fiscal year ended December 31, 2022 filed on March 1, 2023 (the "Form 10-K"), our quarterly report on Form 10-Q for the quarter ended March 31, 2023 filed on May 2, 2023, and in our other filings with the U.S. Securities and Exchange Commission (the “SEC”), which are available at the SEC’s website www.sec.gov. Interim Financial Information Unaudited financial information as of and for interim periods, including the three month periods ended June 30, 2023, March 31, 2023, December 31, 2022, June 30, 2022 and March 31, 2022, may not reflect our results of operations for our fiscal year ending, or financial condition as of December 31, 2023, or any other period of time or date. As previously disclosed in the Form 10-K, the Company adopted the new guidance on accounting for current expected credit losses on financial instruments (“CECL”) effective as of January 1, 2022. Quarterly amounts previously reported on our quarterly reports on Form 10-Q for the periods ended March 31, 2022, June 30, 2022 and September 30, 2022 do not reflect the adoption of CECL. In the fourth quarter of 2022, the Company recorded a provision for credit losses totaling $20.9 million, including $11.1 million related to the retroactive effect of adopting CECL for all previous quarterly periods in the year ended December 31, 2022, including loan growth and changes to macro-economic conditions during the period. Recast amounts included in the earnings release and accompanying presentation reflect the impacts of the adoption of CECL on each interim period of 2022. See the Form 10-K for more details on the adoption of CECL and related effects to quarterly results for each quarter in the year ended December 31, 2022. Non-GAAP Financial Measures The Company supplements its financial results that are determined in accordance with accounting principles generally accepted in the United States of America (“GAAP”) with non-GAAP financial measures, such as “pre-provision net revenue (PPNR)”, “core pre-provision net revenue (Core PPNR)”, “core noninterest income”, “core noninterest expenses”, “core net income”, “core return on assets (Core ROA)”, “core return on equity (Core ROE)”, “core efficiency ratio”, “tangible stockholders’ equity (book value) per common share”, “tangible common equity ratio, adjusted for unrealized losses on debt securities held to maturity”, and “tangible stockholders' equity (book value) per common share, adjusted for unrealized losses on debt securities held to maturity”, and "tangible stockholders' book value per common share, adjusted for unrealized losses on securities held to maturity". This supplemental information is not required by, or is not presented in accordance with GAAP. The Company refers to these financial measures and ratios as “non-GAAP financial measures” and they should not be considered in isolation or as a substitute for the GAAP measures presented herein. We use certain non-GAAP financial measures, including those mentioned above, both to explain our results to shareholders and the investment community and in the internal evaluation and management of our businesses. Our management believes that these non-GAAP financial measures and the information they provide are useful to investors since these measures permit investors to view our performance using the same tools that our management uses to evaluate our past performance and prospects for future performance, especially in light of the additional costs we have incurred in connection with the Company’s restructuring activities that began in 2018 and continued in 2023, including the effect of non-core banking activities such as the sale of loans and securities and other repossessed assets, the valuation of securities, derivatives, loans held for sale and other real estate owned, impairment of investments, early repayment of FHLB advances, and other non-recurring actions intended to improve customer service and operating performance. While we believe that these non-GAAP financial measures are useful in evaluating our performance, this information should be considered as supplemental and not as a substitute for or superior to the related financial information prepared in accordance with GAAP. Additionally, these non-GAAP financial measures may differ from similar measures presented by other companies. Exhibit 2 reconciles these non-GAAP financial measures to reported results.

34 amerantbank.com Explanation of Certain Non-GAAP Financial Measures This presentation contains certain adjusted financial information or non-GAAP financial measures, including “pre-provision net revenue (PPNR)”, “core pre- provision net revenue (Core PPNR)”, “core noninterest income”, “core noninterest expenses”, “core net income (loss)”, “core return on assets (Core ROA)”, “core return on equity (Core ROE)”, “core efficiency ratio”, “tangible stockholders’ equity (book value) per common share”,“tangible common equity ratio, adjusted for unrealized losses/gains on debt securities held to maturity”, and “tangible stockholders' equity (book value) per common share, adjusted for unrealized losses/gains on debt securities held to maturity". See below detailed information on adjustments included in this presentation: • the $1.7 million loss on the sale of the Beacon operations center during the fourth quarter of 2020 • the $11.9 million, $7.1 million, $15.4 million, $3.4 million, $8.8 million and $12.1 million of restructuring costs in 2020, 2021, 2022, the first and second quarters of 2023 and the first six months of 2023, respectively, related to staff reduction costs, legal, consulting and other professional fees, disposition of fixed assets, digital transformation expenses, branch/office closure expenses and related charges, and contract termination costs • the effect of non-core banking activities such as the sale of loans and securities and other repossessed assets, the valuation of securities, derivatives, loans held for sale and other real estate owned, the early repayment of FHLB advances, impairment of investments, and other non- recurring actions intended to improve customer service and operating performance • the $62.4 million gain on the sale of the Company's headquarters building in 2021 The Company uses certain non-GAAP financial measures, within the meaning of SEC Regulation G, which are included in this Presentation to explain our results and which are used in our internal evaluation and management of the Company’s businesses. The Company’s management believes these non-GAAP financial measures and the information they provide are useful to investors since these measures permit investors to view the Company’s performance using the same tools that management uses to evaluate the Company’s past performance and prospects for future performance. The Company believes these are especially useful in light of the effects of restructuring costs that began in 2018 and continued in 2023, as well as the sale of the Company's headquarters building in the fourth quarter of 2021, the sale of the Beacon operations center in the fourth quarter of 2020, and the effect of non-core banking activities such as the sale of loans and securities and other repossessed assets, the valuation of securities, derivatives, loans held for sale and other real estate owned, the early repayment of FHLB advances, impairment of investments, and other non-recurring actions intended to improve customer service and operating performance. These as-adjusted measures are not in accordance with generally accepted accounting principles (“GAAP”). This Appendix 2 reconciles these adjustments to reported results.

In 2020, potential dilutive instruments were not included in the dilutive earnings per share computation because the Company reported a net loss and their inclusion would have an antidilutive effect. For all of the other periods shown, potential dilutive instruments were included in the diluted earnings per share computation because, when the unamortized deferred compensation cost related to these shares was divided by the average market price per share in those periods, fewer shares would have been purchased than restricted shares assumed issued. Therefore, in those periods, such awards resulted in higher diluted weighted average shares outstanding than basic weighted average shares outstanding, and had a dilutive effect in per share earnings. (14) Other intangible assets primarily consist of mortgage servicing rights of $1.3 million, $1.4 million, $1.3 million and $0.6 million at June 30, 2023, March 31, 2023, December 31, 2022 and December 31, 2021, respectively, and are included in other assets in the Company's consolidated balance sheets.
