Readers are cautioned not to place undue reliance on the forward - looking statements contained in this presentation in that actual results could differ materially from those indicated in or implied by such forward - looking statements, due to a variety of factors . These factors include, but are not limited to, changes in the Company's operating or expansion strategy ; the availability of and costs associated with obtaining adequate and timely sources of liquidity ; the ability to maintain credit quality ; the effect of steps the Company takes in response to the COVID - 19 pandemic ; the severity and duration of the pandemic, including the effectiveness of vaccination efforts and developments with respect to COVID - 19 variants ; the pace of recovery when the pandemic subsides and the heightened impact it has on many of the risks described herein ; the effects of the pandemic on, among other things, the Company’s operations, liquidity, and credit quality ; general market and economic conditions ; unemployment ; possible adverse rulings, judgments, settlements and other outcomes of pending or future litigation (including litigation arising from the Company’s participation in and administration of programs related to the COVID - 19 pandemic (including the PPP)) ; the ability of the Company to collect amounts due under loan agreements ; changes in consumer preferences and loan demand ; effectiveness of the Company's interest rate risk management strategies ; laws and regulations affecting financial institutions in general or relating to taxes ; the effect of pending or future legislation ; the ability of the Company to repurchase its common stock on favorable terms ; the ability of the Company to successfully implement its acquisition and branch strategy ; the ability to satisfy closing conditions and receive regulatory approvals associated with the Company’s pending mergers and acquisitions ; delays in closing the Company’s pending mergers and acquisitions ; changes in interest rates, deposit flows, real estate values, and capital markets ; inflation ; customer acceptance of the Company's products and services ; changes or disruptions in technology and IT systems (including cyber threats, attacks and events) ; changes in accounting principles relating to loan loss recognition (current expected credit losses, or CECL) ; the benefits associated with the Company’s early retirement program and completed and future branch closures and sales ; and other risk factors .

Any forward - looking statement speaks only as of the date of this presentation , and the Company undertakes no obligation to update these forward - looking statements to reflect events or circumstances that occur after the date of this presentation . Annualized, pro forma, projected and estimated numbers are used for illustrative purpose only, are not forecasts and may not reflect actual results . Non - GAAP Financial Measures . This presentation contains financial information determined by methods other than in accordance with U . S . generally accepted accounting principles (GAAP) . The Company's management uses these non - GAAP financial measures in their analysis of the Company's performance . These measures adjust GAAP performance measures to, among other things, include the tax benefit associated with revenue items that are tax - exempt, as well as exclude from income available to common shareholders, non - interest income, and non - interest expense certain income and expenses related to significant non - core activities, such as merger - related expenses, expenses related to the Company’s early retirement program, gain on sale of branches, and net branch right - sizing expenses . In addition, the Company also presents certain figures based on tangible common stockholders’ equity, tangible assets, and tangible book value, which exclude goodwill and other intangible assets . The Company further presents certain figures that are exclusive of the impact of PPP loans . The Company’s management believes that these non - GAAP financial measure are useful to investors because they, among other things, present the results of the Company’s ongoing operations without the effect of mergers or other items not central to the Company’s ongoing business, as well as normalize for tax effects . Management, therefore, believes presentations of these non - GAAP financial measures provide useful supplemental information that is essential to a proper understanding of the operating results of the Company's core businesses, and management uses these non - GAAP measures to assess the performance of the Company’s core businesses as related to prior financial periods . These non - GAAP 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 . Where non - GAAP financial measures are used, the comparable GAAP financial measure, as well as the reconciliation to the comparable GAAP financial measure, can be found in the appendix to this presentation .
