2 This presentation contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward- looking statements are not statements of historical fact, are based on certain assumptions and often include the words “believes,” “expects,” “anticipates,” “estimates,” “forecasts,” “intends,” “plans,” “targets,” “potentially,” “probably,” “projects,” “outlook” or similar expressions or future or conditional verbs such as “may,” “will,” “should,” “would” and “could.” These statements relate to our financial condition, results of operations, beliefs, plans, objectives, goals, expectations, assumptions and statements about future performance or business. Readers are cautioned not to place undue reliance on any forward-looking statements. Moreover, you should treat these statements as speaking only as of the date they are made and based only on information then actually known to the Company. The Company does not undertake and specifically disclaims any obligation to revise any forward-looking statements to reflect the occurrence of anticipated or unanticipated events or circumstances after the date of such statements whether as a result of new information, future events or otherwise. These forward-looking statements are subject to known and unknown risks, uncertainties and other factors that could cause our actual results for future periods to differ materially from those expressed in any forward-looking statements by, or on behalf of, us, and could negatively affect the Company’s operating results and stock price performance including: • the uncertain impacts of quantitative tightening and current and future monetary policies of the Federal Reserve; • legislative or regulatory changes that adversely affect our business, including changes in banking, securities and tax law, in regulatory policies and principles, or the interpretation of regulatory capital or other rules, and including changes as a result of the COVID-19 Pandemic; • our ability to attract and retain deposits; • liquidity issues, including our ability to borrow funds or raise additional capital, if necessary; • the effects of climate change, severe weather events, natural disasters, pandemics, epidemics and other public health crises, acts of war or terrorism, and other external events on our business; The Company reports its results in accordance with United States generally accepted accounting principles (“GAAP”). However, management believes that certain non-GAAP performance measures used in managing the business may provide meaningful information about underlying trends in its business. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s reported results prepared in accordance with GAAP. Slides containing a discussion and reconciliation of non-GAAP financial measures are contained at the end of this presentation. All dollars throughout the entire presentation are in millions unless otherwise noted, except per share amounts.
