Forward-Looking Statements. This presentation may contain “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements express management’s current expectations, estimates or projections of future events, results or long-term goals, and are generally identifiable by the use of words such as “believe,” “expect,” “anticipate,” “plan,” “intend,” “estimate,” “may,” “will,” “would,” “could,” “should” or other similar expressions. All statements in this material speak only as of the date they are made, and we undertake no obligation to update any statement except to the extent required by law. Forward-looking statements are not guarantees of performance and are inherently subject to known and unknown risks, uncertainties and assumptions that are difficult to predict and could cause actual results or performance to differ materially from those expressed in or implied by the forward-looking statements. Factors that could cause actual results or performance to differ from those discussed in the forward-looking statements include the risks identified from time to time in our public filings with the SEC, including those risks identified in “Item 1A. Risk Factors” of Part I of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, as supplemented by any additional risks identified in the Company’s subsequent Form 10-Qs. These risks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements. Use of Non-GAAP Financial Measures. This presentation contains certain financial information determined by methods other than in accordance with accounting principles generally accepted in the United States (“GAAP”). These non-GAAP financial measures include “Tangible Book Value per Share” , “Tangible Common Equity to Tangible Assets” and “Efficiency Ratio”. The Company believes that these non-GAAP financial measures provide both management and investors a more complete understanding of the Company’s profitability. These non-GAAP financial measures are supplemental and are not a substitute for any analysis based on GAAP Measures. Not all companies use the same calculation of these measures; therefore, this presentation may not be comparable to other similarly titled measures as presented by other companies. Reconciliations of these non-GAAP measures are provided in the Appendix section of this presentation. Sources of Information: Company Management and S&P Global Market Intelligence Disclaimer
