These forward-looking statements reflect our current views with respect to, among other things, future events and our financial performance. These statements are often, but not always, made through the use of words or phrases such as “may,” “should,” “could,” “predict,” “potential,” “believe,” “will likely result,” “expect,” “continue,” “will,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “strive,” “projection,” “would,” and “outlook,” or the negative version of those words or other comparable words or phrases of a future or forward-looking nature. These forward-looking statements are not historical facts, and are based on current expectations, estimates, and projections about our industry, management’s beliefs, and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions, and uncertainties that are difficult to predict. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. The following risks, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements: The impact of the COVID-19 pandemic and the responses of governmental authorities on our operations, including declines in credit quality, strains on capital and liquidity, fluctuations in our payment processing business, and declines in deposits; our strategic decision to focus on the greater Atlanta market may not positively impact our financial condition in the expected timeframe, or at all; costs associated with our growth and hiring initiatives in the Atlanta market area; risks associated with increased geographic concentration, borrower concentration and concentration in commercial real estate and commercial and industrial loans resulting from our exit of the Tennessee and northwest Georgia markets and our strategic realignment; our strategic decision to increase our focus on SBA and franchise lending may expose us to additional risks associated with these types of lending, including industry concentration risks, our ability to sell the guaranteed portion of SBA loans, the impact of negative economic conditions on small businesses’ ability to repay the non-guaranteed portions of SBA loans, and changes to applicable federal regulations; risks associated with our ability to manage the planned growth of our payment processing business, including evolving regulations, security risks, and unforeseen increases in transaction volume resulting from changes in our customers’ businesses and changes in the competitive landscape for payment processing; changes in asset quality and credit risk; the cost and availability of capital; customer acceptance of our products and services; customer borrowing, repayment, investment and deposit practices; the introduction, withdrawal, success and timing of business initiatives; the impact, extent, and timing of technological changes; severe catastrophic events in our geographic area; a weakening of the economies in which we conduct operations may adversely affect our operating results; the U.S. legal and regulatory framework could adversely affect the operating results of the Company; the interest rate environment may compress margins and adversely affect net interest income; our ability to anticipate or respond to interest rate changes correctly and manage interest rate risk presented through unanticipated changes in our interest rate risk position and/or short- and long-term interest rates; changes in trade, monetary and fiscal policies of various governmental bodies and central banks could affect the economic environment in which we operate; our ability to determine accurate values of certain assets and liabilities; adverse developments in securities, public debt, and capital markets, including changes in market liquidity and volatility; unanticipated changes in our liquidity position, including but not limited to our ability to enter the financial markets to manage and respond to any changes to our liquidity position; the impact of the transition from LIBOR and our ability to adequately manage such transition; adequacy of our risk management program; increased competitive pressure due to consolidation in the financial services industry; risks related to security breaches, cybersecurity attacks, and other significant disruptions in our information technology systems; and other risks and factors identified in our most recent annual report on Form 10-K and our other reports filed with or furnished to the Securities and Exchange Commission (“SEC”) from time to time. Statements included in this presentation include non-GAAP financial measures and should be read along with the accompanying tables, which provide a reconciliation of non-GAAP financial measures common to GAAP financial measures. Atlantic Capital management uses non-GAAP financial measures, including: (i) taxable equivalent net interest income, (ii) taxable equivalent net interest margin, (iii) tangible book value per share, (iv) tangible common equity to tangible assets; (v) pre-provision net revenue, (vi) allowance for credit losses to loans held for investment excluding PPP, and (vii) allowance for loan losses to loans held for investment excluding PPP. Tangible common equity excludes goodwill from shareholders’ equity. Management believes that non-GAAP financial measures provide a greater understanding of ongoing performance and operations, and enhance comparability with prior periods. Non-GAAP financial measures should not be considered as an alternative to any measure of performance or financial condition as determined in accordance with GAAP, and investors should consider Atlantic Capital’s performance and financial condition as reported under GAAP and all other relevant information when assessing the performance or financial condition of the Company. Non-GAAP financial measures have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for analysis of the results or financial condition as reported under GAAP. Non-GAAP financial measures may not be comparable to non-GAAP financial measures presented by other companies.
