The Company can give no assurance that any goal or plan or expectation set forth in forward-looking statements can be achieved and readers are cautioned not to place undue reliance on such statements. The forward-looking statements are made as of the date of this presentation, and the Company does not intend, and assumes no obligation, to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events or circumstances, except as required by applicable law. Further Information: This presentation should be read together with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and the related notes thereto included in our Form 10-K and quarterly reports.

ABOUT NON-GAAP FINANCIAL MEASURES Certain of the financial measures and ratios we present, including “average tangible assets,” “return on average tangible assets,” “average tangible common equity,” “return on average tangible common equity,” “non-interest expense to average assets, adjusted,” “adjusted non-interest expense,” “adjusted efficiency ratio,” “adjusted net income,” “adjusted earnings per share - diluted,” “adjusted return on average tangible assets,” “adjusted return on average tangible common equity,” and “fully taxable equivalent” metrics, are supplemental measures that are not required by, nor presented in accordance with, U.S. generally accepted accounting principles (GAAP). We refer to these financial measures and ratios as “non-GAAP financial measures.” We consider the use of select non-GAAP financial measures and ratios to be useful for financial and operational decision making and useful in evaluating period-to-period comparisons. We believe that these non-GAAP financial measures provide meaningful supplemental information regarding our performance by excluding certain expenditures or assets that we believe are not indicative of our primary business operating results or by presenting certain metrics on a fully taxable equivalent basis. We believe that management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, analyzing and comparing past, present and future periods. These non-GAAP financial measures should not be considered a substitute for financial information presented in accordance with GAAP and you should not rely on non- GAAP financial measures alone as measures of our performance. The non- GAAP financial measures we present may differ from non-GAAP financial measures used by our peers or other companies. We compensate for these limitations by providing the equivalent GAAP measures whenever we present the non-GAAP financial measures and by including a reconciliation of the impact of the components adjusted for in the non- GAAP financial measure so that both measures and the individual components may be considered when analyzing our performance. A reconciliation of non-GAAP financial measures to the comparable GAAP financial measures is included in the appendix. 3
