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 outsourcing relationship with FIS, as well as other statements 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, 2020, in our quarterly report on Form 10-Q for the quarter ended June 30, 2021 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, 2021 and the three month period ended December 31, 2020, may not reflect our results of operations for our fiscal year ended, or financial condition as of December 31, 2021, 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 “pre-provision net revenue (PPNR)”, “core pre-provision net revenue (Core PPNR)”, “core net income (loss)”, “core net income (loss) per share (basic and diluted)”, “core return on assets (Core ROA)”, “core return on equity (Core ROE)", "core efficiency ratio”, and “tangible stockholders’ equity (book value) per common share”. 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 2021, including the effect of non-core banking activities such as the sale of loans and securities, the sale of our corporate headquarters in the fourth quarter of 2021, 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.

27 amerantbank.com Explanation of Certain Non-GAAP Financial Measures This Presentation contains certain adjusted financial information, and their effects on noninterest income, noninterest expense, income taxes, net income, Core pre-provision net revenue, ROA and ROE and certain other financial ratios. These adjustments include: • the $1.7 million loss on the sale of the Beacon operations center during the fourth quarter of 2020 • the $2.8 million net gain on the sale of vacant Beacon land during the fourth quarter of 2019, • spin-off expenses totaling $6.7 million in 2018, beginning in the fourth quarter of 2017 and continuing to the fourth quarter of 2018, • the $6.4 million, $5.0 million, $11.9 million and $7.1 million in restructuring expenses in 2018, 2019, 2020 and 2021, respectively, related to staff reduction costs, legal and strategic advisory costs, rebranding costs, digital transformation costs, branch closure expenses and a lease impairment charge • the effect of non-core banking activities such as the sale of loans and securities, 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 our spin-off and related restructuring expenses, 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, the sale of the vacant Beacon land in the fourth quarter of 2019 and the effect of non-core banking activities such as the sale of loans and securities, 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.

The Company leased-back the property for an 18-year term. The provision for income tax expense includes $16.1 million related to this transaction in the three months and year ended December 31, 2021. (2) The Company leased-back the property for a 2-year term. (3) Expenses incurred for actions designed to implement the Company’s 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, enhanced sales tools and training, expanded product offerings and improved customer analytics to identify opportunities. (4) In 2021, includes expenses in connection with the departure of the Company's Chief Operating Officer and the elimination of various other support function positions, including the NYC LPO. In 2020, the Board of Directors of the Company adopted a voluntary retirement plan for certain eligible long-term employees and an involuntary severance plan for certain other positions consistent with the Company's efforts to streamline operations and better align its operating structure with 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 werel 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 which began in 2021. (5) Consist of: (i) expenses in connection with the clean-up merger and related transactions, and (ii) $0.7 million to related consulting services received from FIS. (6)Expenses related to the lease termination of the Fort Lauderdale branch in 2021 and, and the closures of one branch in Fort Lauderdale, Florida and another branch in Houston, Texas in 2020. (7) 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. (8) In 2021 and in 2020, 2019 and 2018, amounts were calculated based upon the effective tax rate for the periods of 23.41%, 60.27%, 19.83% and 20.38%, respectively. (9) 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. (10) In 2021, potential dilutive instruments consisted of unvested shares of restricted stock, restricted stock units and performance share units (unvested share of restricted stock and restricted stock units for all of the other periods shown). 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. In 2021 and in 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 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 averages shares outstanding than basic weighted average shares outstanding, and had a dilutive effect in per share earnings. (11) Other intangible assets consist of, among other things, mortgage servicing rights of $0.6 million at December 31, 2021, and are included in other assets in the Company's consolidated balance sheets. We had no mortgage servicing rights at any of the other periods shown.
