Forward-Looking Statements Certain statements contained in this presentation that are not historical facts may constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and are intended to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements involve risks and uncertainties. These statements, which are based on certain assumptions and describe the Company’s future plans, strategies and expectations, can generally be identified by the use of the words “may,” “will,” “should,” “could,” “would,” “plan,” “potential,” “estimate,” “project,” “believe,” “intend,” “anticipate,” “expect,” “target” and similar expressions. These statements include, among others, statements regarding the Company’s intent, belief or expectations with respect to economic conditions, trends affecting the Company’s financial condition or results of operations, and the Company’s exposure to market, liquidity, interest-rate and credit risk. Forward-looking statements are based on the current assumptions underlying the statements and other information with respect to the beliefs, plans, objectives, goals, expectations, anticipations, estimates and intentions of management and the financial condition, results of operations, future performance and business are only expectations of future results. Although the Company believes that the expectations reflected in the Company’s forward-looking statements are reasonable, the Company’s actual results could differ materially from those projected in the forward-looking statements as a result of, among other important factors, changes in interest rates; general economic conditions (including the impact of ongoing armed conflicts, tariffs, inflation, and concerns about liquidity) on a national basis or in the local markets in which the Company operates; turbulence in the capital and debt markets; competitive pressures from other financial institutions; changes in consumer behavior due to changing political, business and economic conditions, or legislative or regulatory initiatives; changes in the value of securities and other assets in the Company’s investment portfolio; increases in loan and lease default and charge-off rates; the adequacy of allowances for loan and lease losses; decreases in deposit levels that necessitate increases in borrowing to fund loans and investments; the diversion of management’s attention from ongoing business operations and opportunities; operational risks including, but not limited to, cybersecurity incidents, fraud, natural disasters, and future pandemics; changes in regulation; the possibility that future credit losses may be higher than currently expected due to changes in economic assumptions and adverse economic developments; the risk that goodwill and intangibles recorded in the Company’s financial statements will become impaired; and changes in assumptions used in making such forward-looking statements; and the other risks and uncertainties detailed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 and other filings submitted to the U.S. Securities and Exchange Commission (“SEC”). Forward-looking statements speak only as of the date on which they are made. The Company does not undertake any obligation to update any forward-looking statement to reflect circumstances or events that occur after the date the forward-looking statements are made.
