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; changes in general market and economic conditions; increased unemployment; labor shortages; possible adverse rulings, judgments, settlements and other outcomes of pending or future litigation; the ability of the Company to collect amounts due under loan agreements; changes in consumer preferences and loan demand; the 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 manage and implement its acquisition strategy and integrate acquired institutions; difficulties and delays in integrating an acquired business or fully realizing cost savings and other benefits of mergers and acquisitions; changes in interest rates, deposit flows, real estate values, and capital markets; increased 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; political crises, war, and other military conflicts (including the ongoing military conflicts between Russia and Ukraine and between Israel and Hamas) or other major events, or the prospect of these events; increased competition; changes in governmental policies; loss of key employees; the soundness of other financial institutions and indirect exposure related to the closings of Silicon Valley Bank (“SVB”), Signature Bank and Silvergate Bank and their impact on the broader market through other customers, suppliers and partners (or that the conditions which resulted in the liquidity concerns with SVB, Signature Bank and Silvergate Bank may also adversely impact, directly or indirectly, other financial institutions and market participants with which the Company has commercial or deposit relationships); increased delinquency and foreclosure rates on commercial real estate loans; and other risk factors. Other relevant risk factors may be detailed from time to time in the Company's press releases and filings with the U.S. Securities and Exchange Commission, including, without limitation, the Company’s Form 10-K for the year ended December 31, 2022, and the Company’s Form 10-Q for the quarterly period ended March 31, 2023. In addition, there can be no guarantee that the board of directors (“Board”) of the Company will approve a quarterly dividend in future quarters, and the timing, payment, and amount of future dividends (if any) is subject to, among other things, the discretion of the Board and may differ significantly from past dividends. 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 and capital adequacy. 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 net income (including on a per share diluted basis), pre-tax, pre-provision earnings, net charge-offs, income available to common shareholders, non-interest income, and non-interest expense certain income and expense items attributable to, for example, merger activity (primarily including merger-related expenses and Day 2 CECL provisions), gains and/or losses on sale of branches, net branch right-sizing initiatives, loss on redemption of trust preferred securities, gain on sale of intellectual property, FDIC special assessment charges and gain/loss on the sale of AFS investment securities. The Company has updated its calculation of certain non-GAAP financial measures to exclude the impact of gains or losses on the sale of AFS investment securities in light of the impact of the Company’s strategic AFS investment securities transactions during the fourth quarter of 2023, and has presented past periods on a comparable basis. 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, and presents certain other figures to include the effect that accumulated other comprehensive income could have on the Company’s capital levels . The Company further presents certain figures that are exclusive of the impact of deposits and/or loans acquired through acquisitions, mortgage warehouse loans, and/or energy loans, or gains and/or losses on the sale of securities. The Company’s management believes that these non-GAAP financial measures 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, present the Company’s capital inclusive of the potential impact of AOCI (primarily comprised of unrealized losses on securities), as well as normalize for tax effects and certain other 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 ongoing businesses, and management uses these non-GAAP financial measures to assess the performance of the Company’s ongoing 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.
