2 Forward-Looking Statements This presentation contains “forward-looking statements” within the meaning of the Securities Act of 1933 and the Securities Exchange Act of 1934, including statements with respect to our 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,” and other similar words and expressions of the future. Forward-looking statements, including those as 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, 2019, in our quarterly report on Form 10-Q for the fiscal quarter ended June 30, 2020 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 and twelve month periods ended December 31, 2020 and the three month period ended December 31, 2019, may not reflect our results of operations for our fiscal year ended, or financial condition as of December 31, 2020, or any other period of time or date. 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 “adjusted noninterest income”, “adjusted noninterest expense”, “adjusted net income (loss)”, “operating income”, “adjusted net income (loss) per share (basic and diluted)”, “adjusted return on assets (ROA)”, “adjusted return on equity (ROE)”, and other ratios. This supplemental information is not required by, or is not presented in accordance with, U.S. generally accepted accounting principles (“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 into 2020, the one-time loss on sale of the Beacon operations center in the fourth quarter of 2020, the one-time gain on sale of the vacant Beacon land in the fourth quarter of 2019, the Company’s increases of its allowance for loan losses and net gains on sales of securities in the first, second and third quarters of 2020. 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. See Appendix 1 “Non-GAAP Financial Measures Reconciliations” of the earnings presentation for a reconciliation of these non-GAAP financial measures to their GAAP counterparts.

These as-adjusted measures are not in accordance with generally accepted accounting principles (“GAAP”). This Appendix 2 reconciles these adjustments to reported results. 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 our spin-off and related restructuring expenses, as well as the sale of the Beacon operations center in the fourth quarter of 2020, the sale of vacant Beacon land in the fourth quarter of 2019, the sale of our New York City building in third quarter 2017, the charges to our deferred tax assets in fourth quarter 2017 resulting from the enactment of the 2017 Tax Act in December 2017, and other adjustments mentioned above. No adjustments were made to the 2015 and 2016 financial information.

38 (1) The Company leased-back the property for a 2-year term. (2) Expenses incurred for actions designed to implement the Company’s strategy as a new independent company. 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, enhanced sales tools and training, expanded product offerings and improved customer analytics to identify opportunities. (3) On October 9, 2020, the Board of Directors of the Company adopted a voluntary early retirement plan for certain eligible long-term employees and an involuntary severance plan for certain other positions consistent with the Company's effort to streamline operations and better align its operating structure with its business activities. 31 employees elected to participate in the voluntary plan, all of whom retired on or before December 31, 2020. The involuntary plan impacted 31 employees most of whom no longer worked for the Company and/or its subsidiaries by December 31, 2020. On December 28, 2020, the Company determined the termination costs and annual savings related to the voluntary and involuntary plans. The Company incurred approximately $3.5 million and $1.8 million in one-time termination costs in the fourth quarter of 2020 in connection with the voluntary and involuntary plans, respectively, the majority of which will be paid over time in the form of installment payments until December 2021. The Company estimates that the voluntary and involuntary plans will yield estimated annual savings of approximately $4.2 million and $5.5 million, respectively, for combined estimated annual savings of approximately $9.7 million beginning in 2021. (4) The spin-off caused an unexpected early distribution for U.S. federal income tax purposes from our deferred compensation plan. This distribution was taxable to plan participants as ordinary income during 2018. We partially compensated plan participants, in the aggregate amount of $1.2 million, for the higher tax expense they incurred as a result of the distribution increasing the plan participants' estimated effective federal income tax rates by recording a contribution to the plan on behalf of its participants. The after tax net effect of this $1.2 million contribution for the period ended September 30, 2018, was approximately $952,000. As a result of the early taxable distribution to plan participants, we expensed and deducted for federal income tax purposes, previously deferred compensation of approximately $8.1 million, resulting in an estimated tax credit of $1.7 million, which exceeded the amount of the tax gross-up paid to plan participants. (5) Calculated based upon the estimated annual effective tax rate for the periods, which excludes the tax effect of discrete items, and the amounts that resulted from the permanent difference between spin-off costs that are non-deductible for Federal and state income tax purposes, and total spin-off costs recognized in the consolidated financial statements. The estimated annual effective rate applied for the calculation differs from the reported effective tax rate since it is based on a different mix of statutory rates applicable to these expenses and to the rates applicable to the Company and its subsidiaries (6) Calculated based upon an estimated annual effective rate of 31.71%. (7) As of December 31, 2020 and 2019, potential dilutive instruments consisted of unvested shares of restricted stock and restricted stock units mainly related to the Company’s IPO in 2018, totaling 248,750 and 530,620, respectively. As of December 31, 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. As of December 31, 2019, 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 at those dates, fewer shares would have been purchased than restricted shares assumed issued. Therefore, at that date, such awards resulted in higher diluted weighted averages shares outstanding than basic weighted average shares outstanding, and had a dilutive effect in per share earnings. We had no outstanding dilutive instruments as of any period prior to December 2018.
