Factors that could cause actual results to differ materially from these forward-looking statements include, but are not limited to: (i) the strength of the local, state, national and international economies (including effects of inflationary pressures and supply chain constraints); (ii) the economic impact of any future terrorist threats and attacks, widespread disease or pandemics (including the COVID-19 pandemic in the United States), acts of war or other threats thereof (including the Israeli-Palestinian conflict and the Russian invasion of Ukraine), or other adverse external events that could cause economic deterioration or instability in credit markets, and the response of the local, state and national governments to any such adverse external events; (iii) changes in accounting policies and practices, as may be adopted by state and federal regulatory agencies, the FASB or the PCAOB (including the Company’s adoption of the current expected credit losses ("CECL") methodology); (iv) changes in state and federal laws, regulations and governmental policies concerning the Company’s general business and any changes in response to the recent failures of other banks; (v) changes in interest rates and prepayment rates of the Company’s assets (including the impact of LIBOR phase-out and the recent and potential additional rate increases by the Federal Reserve); (vi) increased competition in the financial services sector, including from non-bank competitors such as credit unions and “fintech” companies, and the inability to attract new customers; (vii) changes in technology and the ability to develop and maintain secure and reliable electronic systems; (viii) unexpected results of acquisitions, which may include failure to realize the anticipated benefits of acquisitions and the possibility that transaction costs may be greater than anticipated; (ix) the loss of key executives or employees; (x) changes in consumer spending; (xi) unexpected outcomes of existing or new litigation involving the Company; (xii) the economic impact of exceptional weather occurrences such as tornadoes, floods and blizzards; (xiii) fluctuations in the value of securities held in our securities portfolio; (xiv) concentrations within our loan portfolio, large loans to certain borrowers, and large deposits from certain clients; (xv) the concentration of large deposits from certain clients who have balances above current FDIC insurance limits and may withdraw deposits to diversify their exposure; (xvi) the level of non-performing assets on our balance sheets; (xvii) interruptions involving our information technology and communications systems or third-party servicers; (xviii) breaches or failures of our information security controls or cybersecurity-related incidents, and (xix) the ability of the Company to manage the risks associated with the foregoing as well as anticipated.

Additional information concerning the Company and its business, including additional factors that could materially affect the Company’s financial results, is included in the Company’s filings with the Securities and Exchange Commission. Non-GAAP Financial Measures This presentation includes certain non-GAAP financial measures. While the Company believes these are useful measures for investors, they are not presented in accordance with GAAP. You should not consider non-GAAP measures in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Because not all companies use identical calculations, the presentation herein of non-GAAP financial measures may not be comparable to other similarly titled measures of other companies. Tax-equivalent adjustments assume a federal tax rate of 21% and state tax rate of 9.5%. For a reconciliation of the non-GAAP measures we use to the most closely comparable GAAP measures, see the Appendix to this presentation.
