Forward-Looking Statements

Statements in this news release regarding expectations and beliefs about future financial performance and financial condition, as well as trends in the Company’s business and markets are “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements often include words such as “believe,” “expect,” “anticipate,” “intend,” “plan,” “estimate,” “project,” “outlook,” or words of similar meaning, or future or conditional verbs such as “will,” “would,” “should,” “could,” or “may.” The forward-looking statements in this news release are based on current information and on assumptions that the Company makes about future events and circumstances that are subject to a number of risks and uncertainties that are often difficult to predict and beyond the Company’s control. As a result of those risks and uncertainties, the Company’s actual financial results in the future could differ, possibly materially, from those expressed in or implied by the forward-looking statements contained in this news release and could cause the Company to make changes to future plans. Those risks and uncertainties include, but are not limited to, the risk of incurring loan losses, which is an inherent risk of the banking business; the risk that the Company will not be able to continue its internal growth rate; the risk that the United States economy will experience slowed growth or recession or will be adversely affected by domestic or international economic conditions and risks associated with the Federal Reserve Board taking actions with respect to interest rates, any of which could adversely affect, among other things, the values of real estate collateral supporting many of the Company’s loans, interest income and interest rate margins and, therefore, the Company’s future operating results; risks associated with changes in income tax laws and regulations; and risks associated with seeking new client relationships and maintaining existing client relationships. Readers of this news release are encouraged to review the additional information regarding these and other risks and uncertainties to which our business is subject that are contained in our Annual Report on Form 10-K for the year ended December 31, 2020 and the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2021, both of which are on file with the Securities and Exchange Commission.

The COVID-19 pandemic has created economic and financial disruptions that have adversely affected, and may continue to adversely affect, our business, operations, financial performance and prospects. Even after the COVID-19 pandemic subsides, it is possible that the U.S. and other major economies experience or continue to experience a prolonged recession, which could materially and adversely affect our business, operations, financial performance and prospects. Statements about the effects of the COVID-19 pandemic on our business, operations, financial performance and prospects may constitute forward-looking statements and are subject to the risk that the actual

impacts may differ, possibly materially, from what is reflected in those forward-looking statements due to factors and future developments that are uncertain, unpredictable and in many cases beyond our control, including the scope and duration of the pandemic, actions taken by governmental authorities in response to the pandemic, and the direct and indirect impact of the pandemic on our customers, third parties and us.

Due to these and other possible uncertainties and risks, readers are cautioned not to place undue reliance on the forward-looking statements contained in this news release, which speak only as of today’s date, or to make predictions based solely on historical financial performance. The Company disclaims any obligation to update forward-looking statements contained in this news release, whether as a result of new information, future events or otherwise, except as may be required by law.
