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, 2021, our quarterly reports on Form 10-Q for the quarter ended March 31, 2022, June 30, 2022, and September 30, 2022 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, 2022 and the three month period ended  December 31, 2021, may not reflect our results of operations for our fiscal year ended, or financial condition as of December 31, 2022, 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 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”, 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 2022, including the effect of non-core banking  activities such as the sale of loans and securities, the valuation of securities, derivatives, loans held for sale and other real estate owned, the sale of our corporate headquarters in the fourth  quarter of 2021, and other non-routine 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. Appendix 1 reconciles these non-GAAP financial measures to reported results.

25 (1)  Net income attributable to the Company results in $22.0 million in the fourth quarter of 2022, excluding the CECL retroactive effect corresponding to the first,  second, and third quarters of 2022. The provision for credit losses attributable to the fourth quarter of 2022 is $16.9 million, excluding the CECL retroactive effect  corresponding to the first, second and third quarters of 2022. In the fourth quarter of 2022, the Company adopted CECL and recorded the related impact on its  ACL in 2022 through a provision for credit losses of $11.1 million.  (2) The Company sold its Coral Gables headquarters for $135.0 million, with an approximate carrying value of $69.9 million at the time of sale and transaction costs of  $2.6 million. The Company leased-back the property for an 18-year term. The provision for income tax expense includes approximately $16.1 million related to  this transaction in the three months ended December 31, 2021. (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) In the fourth quarter of 2022, includes expenses primarily in connection with changes in certain positions within our business units. In the third quarter of 2022 and  the fourth quarter of 2021, includes expenses primarily in connection with the elimination of certain support functions. (5)  Contract termination and related costs associated with third party vendors resulting from the Company’s engagement of FIS. (6)  Includes: (i) expenses in connection with the engagement of FIS of $1.1 million, $1.0 million and $0.5 million in the three months ended December 31, 2022,  September 30, 2022  and December 31, 2021, respectively, and $2.9 million and $0.7 million in the years ended December 31, 2022 and 2021, respectively and  (ii) expenses in connection with the Merger and related transactions of $0.6 million and $0.8 million in the three months and the year ended December 31, 2021,  respectively. (7) In the year ended December 31, 2022, includes $1.6 million of ROU asset impairment associated with the closure of a branch in Pembroke Pines, Florida in 2022. In  the year ended December 31, 2021, includes $0.8 million of ROU asset impairment associated with the lease of the NY loan production office. (8)  Expenses related to the Fort Lauderdale, Florida branch lease termination in 2021 and in Wellington, Florida in 2022. (9)  Fair value adjustment related to one OREO property in New York. (10) Fair value adjustment related to the New York loan portfolio held for sale carried at the lower of cost or fair value. (11) In the years ended December 31, 2022 and 2021, amounts were calculated based upon the effective tax rate for the periods of 21.15%, and 23.41% respectively.  For all of the other periods shown, amounts represent the difference between the prior and current period year-to-date tax effect.  (12) In the three months ended December 31, 2022, September 30, 2022, and December 31, 2021, 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) Other intangible assets consist of, among other things, mortgage servicing rights (“MSRs”) of $1.3 million, $1.0 million and $0.6 million at December 31, 2022,  September 30, 2022 and December 31, 2021, respectively, and are included in other assets in the Company’s consolidated balance sheets.
