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.

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, 2023 filed on March 7, 2024 (the “Form 10-K”), 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 months ended March 31, 2024, December 31, 2023, and March 31, 2023, may not reflect our results of operations for our fiscal year ending, or financial condition, as of December 31, 2024, 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”, “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”. 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 2024, 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 and repossessed assets, the early repayment of FHLB advances, impairment of investments, Bank owned life insurance restructure 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.

Exhibit 2 reconciles these non-GAAP financial measures to GAAP reported results.

The dividend declared in the first quarter of 2024 was paid on February 29, 2024 to shareholders of record at the close of business on February 14, 2024. See 2023 Form 10-K for more information on previous dividend payments in 2023.

(5) Assets held for clients in an agency or fiduciary capacity which are not assets of the Company and therefore are not included in the consolidated financial statements.

(6) In the first quarter of 2024 and in the fourth and third quarter of 2023, includes, $12.4 million, $12.0 million and $7.4 million of provision for credit losses on loans. Provision for unfunded commitments (contingencies) in the fourth and third quarter of 2023, were $0.5 million and $0.6 million, respectively, while there was none in the first quarter of 2024. 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. In the first quarter of 2023, the provision for credit losses on unfunded commitments was $0.3 million.

(7) In the three months ended December 31, 2023, September 30, 2023, June 30, 2023 and March 31, 2023, net income excludes losses of $0.8 million, $0.4 million, $0.3 million and $0.2 million, respectively, attributable to a minority interest in Amerant Mortgage LLC. In the fourth quarter of 2023, the Company increased its ownership interest in Amerant Mortgage to 100% from 80% at September 30, 2023. This transaction had no material impact to the Company’s results of operations in the three months ended December 31, 2023. In connection with the change in ownership interest, which brought the minority interest share to zero, the Company derecognized the equity attributable to noncontrolling interest of $3.8 million at December 31, 2023, with a corresponding reduction to additional paid-in capital.

(8) This presentation contains adjusted financial information determined by methods other than GAAP. This adjusted financial information is reconciled to GAAP in Exhibit 2 - Non-GAAP Financial Measures Reconciliation.

(9) In all the periods shown, potential dilutive instruments consisted of unvested shares of restricted stock, restricted stock units and performance stock units. 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 all the periods shown, 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 in per share earnings.

(10) Operating data for the periods presented have been annualized.

(11) NIM is defined as NII divided by average interest-earning assets, which are loans, securities, deposits with banks and other financial assets which yield interest or similar income.

(12) Calculated based upon the average daily balance of total assets.

(13) Calculated based upon the average daily balance of stockholders’ equity.

(14) Total revenue is the result of net interest income before provision for credit losses plus noninterest income.

(15) Total stockholders’ equity divided by total risk-weighted assets, calculated according to the standardized regulatory capital ratio

calculations.

(16) Tier 1 capital divided by total risk-weighted assets. Tier 1 capital is composed of Common Equity Tier 1 (CET1) capital plus outstanding qualifying trust preferred securities of $62.3 million at each of all the dates presented.

(17) Tier 1 capital divided by quarter to date average assets.

(18) CET1 capital divided by total risk-weighted assets.

(19) Tangible common equity is calculated as the ratio of common equity less goodwill and other intangibles divided by total assets

less goodwill and other intangible assets. Other intangible assets primarily consist of naming rights and mortgage servicing rights and are included in other assets in the Company’s consolidated balance sheets.

(20) Calculated in the same manner described in footnote 19 but also includes unrealized losses on debt securities held to maturity in the balance of common equity and total assets.

(21) Calculated as the ratio of total loans gross divided by total deposits.

(22) Non-performing assets include all accruing loans past due by 90 days or more, all nonaccrual loans and other real estate owned (“OREO”) properties acquired through or in lieu of foreclosure, and other repossessed assets.

(23) Non-performing loans include all accruing loans past due by 90 days or more and all nonaccrual loans

(24) Calculated based upon the average daily balance of outstanding loan principal balance net of unamortized deferred loan origination fees and costs, excluding the allowance for credit losses. See 2023 Form 10-K for more details on charge-offs for all previous periods.

(25) Other operating expenses is the result of total noninterest expense less salary and employee benefits.

(26) Efficiency ratio is the result of noninterest expense divided by the sum of noninterest income and NII.

(27) As of March 31, 2024, December 31, 2023, September 30, 2023, June 30, 2023 and March 31, 2023, includes 65, 67, 98, 93, and 94 FTEs for Amerant Mortgage LLC, respectively.

(28) Core efficiency ratio is the efficiency ratio less the effect of restructuring costs and other non-routine items, described in Exhibit 2 - Non-GAAP Financial Measures Reconciliation.

Exhibit 2- Non-GAAP Financial Measures Reconciliation

The following table sets forth selected financial information derived from the Company’s interim unaudited and annual audited consolidated financial statements, adjusted for certain costs incurred by the Company in the periods presented related to tax deductible restructuring costs, provision for (reversal of) credit losses, provision for income tax expense (benefit), 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 and repossessed assets, the early repayment of FHLB advances, impairment of investments, Bank owned life insurance restructure and other non-routine actions intended to improve customer service and operating performance. The Company believes these adjusted numbers are useful to understand the Company’s performance absent these transactions and events.

____________

(1) In the first quarter of 2024 and in the fourth and third quarter of 2023, includes $12.4 million, $12.0 million and $7.4 million of provision for credit losses on loans, respectively. Provision for unfunded commitments (contingencies) in the fourth and third quarter of 2023, were $0.5 million and $0.6 million, respectively, while there was none in the first quarter of 2024. 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. In the first quarter of 2023, the provision for credit losses on unfunded commitments was $0.3 million.

(2) In the fourth quarter of 2023, the Company completed a restructuring of its bank-owned life insurance (“BOLI”) program. This was executed through a combination of a 1035 exchange and a surrender and reinvestment into higher-yielding general account with a new investment grade insurance carrier. This transaction allowed for higher team member participation through an enhanced split-dollar plan. Estimated improved yields resulting from the enhancement have an earn-back period of approximately 2 years. In the fourth quarter of 2023, we recorded total additional expenses and charges of $4.6 million in connection with this transaction, including: (i) a reduction of $0.7 million to the cash surrender value of BOLI; (ii) transaction costs of $1.1 million, and (iii) income tax expense of $2.8 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) In the three months ended December 31, 2023, includes an aggregate of $1.6 million of nonrecurrent expenses in connection with the engagement of FIS and, to a lesser extent, software expenses related to legacy applications running in parallel to new core banking applications. There were no significant nonrecurrent expenses in connection with engagement of FIS in the three months ended March 31, 2024 and September 30, 2023. In the three months ended June 30, 2023 and March 31, 2023, includes expenses of $2.0 million and $2.6 million, respectively, in connection with the engagement of FIS.

(7) Includes 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 addition, in the three months ended June 30, 2023 includes $0.9 million of accelerated amortization of leasehold improvements and $0.6 million of right-of-use, or ROU asset impairment, associated with the closure of a branch in Miami, FL in 2023. Furthermore, 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) In the three months ended December 31, 2023, includes (i) fair value adjustment of $35.5 million related to an aggregate of $401 million in Houston-based CRE loans held for sale which are carried at the lower of fair value or cost, and (ii) a loss on sale of $2.0 million related to a New York-based CRE loan previously carried at the lower of fair value or cost. In the three months ended September 30, 2023, includes a fair value adjustment of $5.6 million 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, 2024 and March 31, 2023, amounts were calculated based upon the effective tax rate for the period of 21.50% and 21.00%, respectively. 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) In the three months ended December 31, 2023, per share amounts and percentages were calculated using the after-tax impact of non-routine items in noninterest expense of $34.2 million and BOLI tax impact of $2.8 million in the same period. In all other periods shown, per share amounts and percentages were calculated using the after tax impact of non-routine items in noninterest expense.

(14) At March 31, 2024, December 31, 2023 and September 30, 2023, other intangible assets primarily consist of naming rights of $2.4 million, $2.5 million and $2.7 million, respectively, and mortgage servicing rights (“MSRs”) of $1.4 million, $1.4 million and $1.3 million, respectively. At June 30, 2023 and March 31, 2023, other intangible assets primarily consist of MSRs of $1.3 million and $1.4 million, respectively. Other intangible assets are included in other assets in the Company’s consolidated balance sheets.

(15) As of March 31, 2024, December 31, 2023, September 30, 2023, June 30, 2023 and March 31, 2023, amounts were calculated based upon the fair value on debt securities held to maturity, and assuming a tax rate of 25.40%, 25.36%, 25.51%, 25.46% and 25.53%, respectively.

Exhibit 3 - Average Balance Sheet, Interest and Yield/Rate Analysis

The following tables present average balance sheet information, interest income, interest expense and the corresponding average yields earned and rates paid for the periods presented. The average balances for loans include both performing and nonperforming balances. Interest income on loans includes the effects of discount accretion and the amortization of non-refundable loan origination fees, net of direct loan origination costs, accounted for as yield adjustments. Average balances represent the daily average balances for the periods presented.

2 Important Notices and Disclaimers 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, 2023 filed on March 7, 2024 (the "Form 10-K"), 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 March 31, 2024, December 31, 2023, and March 31, 2023,, may not reflect our results of operations for our fiscal year ending, or financial condition as of December 31, 2024, 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”, “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 2024, 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, Bank owned life insurance restructure, 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. Appendix 1 reconciles these non-GAAP financial measures to reported results.

(9) In the three months ended December 31, 2023, includes (i) fair value adjustment of $35.5 million related to an aggregate of $401 million in Houston-based CRE loans held for sale which are carried at the lower of fair value or cost, and (ii) a loss on sale of $2.0 million related to a New York-based CRE loan previously carried at the lower of fair value or cost. In the three months ended September 30, 2023, includes a fair value adjustment of $5.6 million 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, 2024 and March 31, 2023, amounts were calculated based upon the effective tax rate for the period of 21.50% and 21.00%, respectively. 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) In the three months ended December 31, 2023, per share amounts and percentages were calculated using the after-tax impact of non-routine items in noninterest expense of $34.2 million and BOLI tax impact of $2.8 million in the same period. In all other periods shown, per share amounts and percentages were calculated using the after tax impact of non-routine items in noninterest expense. (14) At March 31, 2024, December 31, 2023 and September 30, 2023, other intangible assets primarily consist of naming rights of $2.4 million, $2.5 million and $2.7 million, respectively, and mortgage servicing rights (“MSRs”) of $1.4 million, $1.4 million and $1.3 million, respectively. At June 30, 2023 and March 31, 2023, other intangible assets primarily consist of MSRs of $1.3 million and $1.4 million, respectively. Other intangible assets are included in other assets in the Company’s consolidated balance sheets. (15) As of March 31, 2024, December 31, 2023, September 30, 2023, June 30, 2023 and March 31, 2023, amounts were calculated based upon the fair value on debt securities held to maturity, and assuming a tax rate of 25.40%, 25.36%, 25.51%, 25.46% and 25.53%, respectively.
