2 Forward-Looking Statements This presentation contains “forward-looking statements” including statements with respect to the Company’s objectives, expectations and intentions and other statements that are not historical facts. All statements other than statements of historical fact are statements that could be forward-looking statements. You can identify these forward-looking statements through our use of words such as “may,” “will,” “anticipate,” “assume,” “should,” “indicate,” “would,” “believe,” “contemplate,” “expect,” “estimate,” “continue,” “plan,” “point to,” “project,” “could,” “intend,” “target,” “goals,” “outlooks,” “modeled,” “dedicated,” “create,” and other similar words and expressions of the future. 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 September 30, 2023, June 30, 2023, March 31, 2023, December 31, 2022 and September 30, 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 earnings per share (basic and diluted)”, “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.

31Appendix 1 Non-GAAP Financial Measures Reconciliations (cont’d) (1) As previously disclosed, the Company adopted CECL in the fourth quarter of 2022, effective as of January 1, 2022. See Form 10-K for more details of the CECL adoption and related effects to quarterly results for each quarter in the year ended December 31, 2022. (2) In the third quarter of 2023, includes $7.4 million and $0.6 million of provision for credit losses on loans and unfunded commitments (contingencies), respectively. For all other periods shown, includes provision for credit losses on loans. There was no provision for credit losses on unfunded commitments in the second quarter of 2023 and the fourth quarter of 2022. In the first quarter of 2023, the provision for credit losses on unfunded commitments was $0.3 million. (3) Expenses incurred for actions designed to implement the Company’s business strategy. These actions include, but are not limited to reductions in workforce, streamlining operational processes, rolling out the Amerant brand, implementation of new technology system applications, decommissioning of legacy technologies, enhanced sales tools and training, expanded product offerings and improved customer analytics to identify opportunities. (4) Staff reduction costs consist of severance expenses related to organizational rationalization. (5) Contract termination and related costs associated with third party vendors resulting from the Company’s engagement of FIS. (6) Includes expenses in connection with the engagement of FIS of $2.0 million, $2.6 million and $1.1 million in the three months ended June 30, 2023, March 31, 2023 and December 31, 2022, respectively. (7) Include expenses in connection with the disposition of fixed assets due to the write off of in-development software in the three months ended June 30, 2023. (8) In the three months ended September 30, 2023, consists of expenses in connection with the closure of a branch in Houston, Texas in 2023. In the three months ended June 30, 2023, consists of expenses associated with the closure of a branch in Miami, Florida in 2023, including $0.9 million of accelerated amortization of leasehold improvements and $0.6 million of right-of-use, or ROU asset impairment. In the three months ended March 31, 2023, includes $0.5 million of ROU asset impairment associated with the closure of a branch in Houston, Texas in 2023. (9) Fair value adjustment related to a New York-based CRE loan held for sale carried at the lower of fair value or cost. (10)In the three months ended June 30, 2023, amount represents the loss on sale of repossessed assets in connection with our equipment-financing activities. (11)In the three months ended March 31, 2023, amounts were calculated based upon the effective tax rate for the period of 21.00%. For all of the other periods shown, amounts represent the difference between the prior and current period year-to-date tax effect. (12) Potential dilutive instruments consisted of unvested shares of restricted stock, restricted stock units and performance stock units. In all the periods presented, 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 on per share earnings. (13) At September 30, 2023, other intangible assets primarily consist of naming rights and mortgage servicing rights (“MSRs”) of $2.7 million and $1.3 million, respectively. At June 30, 2023, March 31, 2023 and December 31, 2022, other intangible assets primarily consist of MSRs of $1.3 million, $1.4 million and $1.3 million, respectively. Other intangible assets are included in other assets in the Company’s consolidated balance sheets. (14) In the three months ended September 30, 2023, June 30, 2023, March 31, 2023 and December 31, 2022, amounts were calculated based upon the fair value on debt securities held to maturity, and assuming a tax rate of 25.51%, 25.46%, 25.53% and 25.55%, respectively.
