Interim Financial Information Unaudited financial information as of and for interim periods, including as of and for the three and six month periods ended June 30, 2019 and 2018, may not reflect our results of operations for our fiscal year ended, or financial condition as of December 31, 2019, 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 Net Income per Share (Basic and Diluted), Adjusted Noninterest Expense, Adjusted Return on Equity (ROE), Adjusted Return on Assets (ROA), or other ratios. This supplemental information should not be considered in isolation or as a substitute for the GAAP measures presented herein. We use certain non-GAAP financial measures, including these, 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 2018 in connection with the spin-off and related transactions, and the rebranding and restructuring expenses which began in 2018 and continue in 2019. 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 2 “Non-GAAP Financial Measures Reconciliations” for a reconciliation of these non-GAAP financial measures to their GAAP counterparts.

27 Appendix 2 Non-GAAP Financial Measures Reconciliations 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, efficiency ratios, ROA and ROE. These adjustments include: • the $10.5 million net gain on the sale of the Company’s New York City building during the third quarter of 2017, • the $9.6 million expense in the fourth quarter of 2017 resulting from the 2017 Tax Act, • spin-off expenses totaling $6.7 million in 2018 and $5.2 million in 2017, beginning in the fourth quarter of 2017 and continuing to the fourth quarter of 2018, which are not deductible for Federal and state income tax purposes, • the $6.4 million, $0.9 million and $2.7 million in restructuring expenses in the fourth quarter of 2018, first quarter of 2019 and second quarter of 2019, respectively, related to staff reduction costs, legal and strategic advisory costs, rebranding costs, and other expenses in the fourth quarter of 2018, rebranding costs of $0.9 million in the first quarter of 2019 and rebranding costs and staff reduction costs in the second quarter of 2019. 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 the first and second quarters of 2019 and in 2018 and 2017, in light of the effects of our spin-off and related restructuring expenses, as well as the sale of our New York City building in third quarter 2017 and the charges to our deferred tax assets in fourth quarter 2017 resulting from the enactment of the 2017 Tax Act in December 2017.

32 Appendix 2 Non-GAAP Financial Measures Reconciliations (cont’d) (1) 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. (2) 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 June 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. (3) 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 difference between spin-off costs that are permanently 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. (4) Calculated based upon an estimated annual effective rate of 31.71%. (5) As of June 30, 2019, potential dilutive instruments included 738,138 unvested shares of restricted stock, including 736,839 shares of restricted stock issued in December 2018 in connection with the Company’s IPO and 1,299 additional shares of restricted stock issued in January 2019. As of June 30, 2019, these 738,138 unvested shares of restricted stock 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 shares outstanding weighted average than basic shares outstanding weighted average and had a dilutive effect in per share earnings in the six months ended June 30, 2019. We had no outstanding dilutive instruments as of any period prior to December 2018.
