Forward Looking Statements Certain statements in this presentation, other than purely historical information, including estimates, projections, statements relating to the Company's business plans, objectives and expected operating results, and the assumptions upon which those statements are based, are "forward-looking statements" within the meanings of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Forward-looking statements may appear throughout this presentation. These forward-looking statements are generally identified by the words "believes," "expects," "intends," "anticipates," "projects," "future," "confident," "may," "should," "will," "strategy," "plan," "opportunity," "will be," "will likely result," "will continue" or similar references, or references to estimates, predictions or future events. Such forward-looking statements are based upon certain underlying assumptions, risks and uncertainties. Because of the possibility that the underlying assumptions are incorrect or do not materialize as expected in the future, actual results could differ materially from these forward-looking statements. Risks and uncertainties that may affect future results include: interest rate risk, including the effects of changes in interest rates; fluctuations in the values of the securities held in our investment portfolio, including as a result of rising interest rates; competitive pressures, including from non-bank competitors such as credit unions, "fintech" companies and digital asset service providers; pricing pressures on loans and deposits; our ability to successfully manage liquidity risk; changes in credit and other risks posed by the Company's loan portfolio, including declines in commercial or residential real estate values or changes in the allowance for credit losses dictated by new market conditions, accounting standards or regulatory requirements; the concentration of large deposits from certain clients, including those who have balances above current FDIC insurance limits; the imposition of domestic or foreign tariffs or other governmental policies impacting the global supply chain and the value of products produced by our commercial borrowers; changes in local, national and international economic conditions, including the level and impact of inflation, and future monetary policies of the Federal Reserve in response thereto, and possible recession; the effects of recent developments and events in the financial services industry, including the large-scale deposit withdrawals over a short period of time that resulted in recent bank failures; changes in legal and regulatory requirements, limitations and costs, including in response to the recent bank failures; changes in customers' acceptance of the Company's products and services; the occurrence of fraudulent activity, breaches or failures of our or our third-party partners' information security controls or cyber-security related incidents, including as a result of sophisticated attacks using artificial intelligence and similar tools; unexpected outcomes of existing or new litigation involving the Company; the monetary, trade and other regulatory policies of the U.S. government; acts of war or terrorism, including the ongoing Israeli-Palestinian conflict and the Russian invasion of Ukraine, widespread disease or pandemics, or other adverse external events; risks related to climate change and the negative impact it may have on our customers and their business; changes to U.S. tax laws, regulations and guidance; potential changes in federal policy and at regulatory agencies; talent and labor shortages; and any other risks described in the "Risk Factors" sections of reports filed by the Company with the Securities and Exchange Commission (the "SEC").

Disclaimers Non-GAAP Financial Information In addition to the results presented in accordance with U.S. General Accepted Accounting Principles ("GAAP"), the Company routinely supplements its evaluation with an analysis of certain non-GAAP financial measures. The Company believes these non-GAAP financial measures, in addition to the related GAAP measures, provide meaningful information to investors to help them understand the Company's operating performance and trends, and to facilitate comparisons with the performance of peers. These disclosures should not be viewed as a substitute for operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Reconciliations of these non- GAAP financial measures to the most directly comparable GAAP financial measures are included in the Appendix at the end of this presentation on the slides captioned "Reconciliation of Non-GAAP Disclosures." None of the non-GAAP financial information that we have included in this presentation is intended to be considered in isolation or as a substitute for any measure prepared in accordance with GAAP. Investors should note that, because there are no standardized definitions for the calculations as well as the results, our calculations may not be comparable to similarly-titled measures presented by other companies. Also, there may be limits in the usefulness of these measures to investors. As a result, we encourage readers to consider our consolidated financial statements in their entirety and not to rely on any single financial measure. No Offer or Solicitation This presentation shall not constitute an offer to sell, or the solicitation of an offer to buy, securities, nor shall there be any offer or sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful. Neither the SEC nor any other regulatory body has approved or disapproved of the securities of the Company or passed upon the accuracy or adequacy of this presentation. Any representation to the contrary is a criminal offense. Except as otherwise indicated, this presentation speaks as to the date hereof. The delivery of this presentation shall not, under any circumstances, create any implication that there has been no change in the affairs of the Company after the date hereof. 3
