Forward-looking statements include statements concerning Amerant Bancorp Inc.’s (the “Company”) objectives, expectations, beliefs, projections, future plans and strategies, anticipated events or trends, intentions and other matters that are not historical facts. Examples of forward-looking statements include but are not limited to: our future operating or financial performance, including revenues, expenses, expense savings, income or loss and earnings or loss per share, and other financial items; statements regarding expectations, plans or objectives for future operations, products or services, and our expectations on loan recoveries, or reaching positive resolutions on problem loans, or significantly reducing special mention and/or non-performing loans. 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,” “outlook,” “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, 2025 filed on February 27, 2026, in our quarterly report on Form 10-Q for the quarter ended March 31, 2026, filed on May 1, 2026, 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 six-month periods ended June 30, 2026 and 2025, and the three-month periods ended March 31, 2026, December 31, 2025 and September 30, 2025, may not reflect our results of operations for our fiscal year ending, or financial condition as of December 31, 2026, 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- tax pre-provision net revenue (PPNR)”, "tangible common equity 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”. 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 business. Management believes that these supplementary 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. 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 GAAP reported results. Beginning in the first quarter of 2026, the Company reviewed and updated its use of non-GAAP financial measures and now presents a limited set of metrics that management uses to evaluate performance and make operating decisions. As part of this update, the Company discontinued the presentation of “Core PPNR”, “core noninterest income”, “core noninterest expense”, “core net income”, “core earnings per share (basic and diluted)”, “core return on assets (Core ROA)”, “core return on equity (Core ROE)”, and “core efficiency ratio” as management determined these measures are no longer primary metrics used internally. This change does not reflect any change in the Company’s underlying business, operations, or GAAP financial results.
