Cautionary Note Regarding Forward-looking Statements
 
This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Statements regarding the potential effects of the COVID-19 pandemic on our business, operations, financial performance and prospects are forward-looking statements. Also, any statement that does not describe historical or current facts is a forward-looking statement. These statements generally can be identified by the use of forward-looking terminology such as “believes”, “expects”, “may”, “will”, “could”, “should”, “projects”, “plans”, “goal”, “targets”, “potential”, “estimates”, “pro forma”, “seeks”, “intends”, or “anticipates”, or similar expressions. Forward-looking statements include discussions of strategy, financial projections, guidance and estimates (including their underlying assumptions), statements regarding plans, objectives, expectations or consequences of various transactions or events, and statements about the future performance, operations, products and services of United Community Banks, Inc. (the “Holding Company”) and its subsidiaries (collectively referred to in this report as “United”).

Because forward-looking statements relate to the future, they are subject to known and unknown risks, uncertainties, assumptions, and changes in circumstances, many of which are beyond our control, and that are difficult to predict as to timing, extent, likelihood and degree of occurrence, and that could cause actual results to differ materially from the results implied or anticipated by the statements. Except as required by law, we expressly disclaim any obligations to publicly update any forward-looking statements whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements, in addition to those described in detail under Part II, Item 1A of this Report - “Risk Factors” - include, but are not limited to the following: 

negative economic and political conditions that adversely affect the general economy, housing prices, the real estate market, the job market, consumer confidence, the financial condition of our borrowers and consumer spending habits, which may affect, among other things, the level of non-performing assets, charge-offs and provision expense;
changes in loan underwriting, credit review or loss policies associated with economic conditions, examination conclusions or regulatory developments, either as they currently exist or as they may be affected by conditions associated with the COVID-19 pandemic;
the COVID-19 pandemic and its effects on the economic and business environments in which we operate;
strategic, market, operational, liquidity and interest rate risks associated with our business;
continuation of historically low interest rates coupled with other potential fluctuations or unanticipated changes in the interest rate environment, including interest rate changes made by the Federal Reserve, the discontinuation of London Interbank Offered Rate (“LIBOR”) as an interest rate benchmark, as well as cash flow reassessments may reduce net interest margin and/or the volumes and values of loans made or held as well as the value of other financial assets;
our lack of geographic diversification and any unanticipated or greater than anticipated adverse conditions in the national or local economies in which we operate;
our loan concentration in industries or sectors that may experience unanticipated or greater than anticipated adverse conditions than other industries or sectors in the national or local economies in which we operate;
the risks of expansion into new geographic or product markets;
risks with respect to future mergers or acquisitions, including our ability to successfully expand and complete acquisitions and integrate businesses and operations that we acquire;
our ability to attract and retain key employees;
competition from financial institutions and other financial service providers including financial technology providers and our ability to attract customers from other financial institutions;
losses due to fraudulent and negligent conduct of our customers, third party service providers or employees;
cybersecurity risks and the vulnerability of our network and online banking portals, and the systems of parties with whom we contract, to unauthorized access, computer viruses, phishing schemes, spam attacks, human error, natural disasters, power loss and other security breaches that could adversely affect our business and financial performance or reputation;
our reliance on third parties to provide key components of our business infrastructure and services required to operate our business;
the risk that we may be required to make substantial expenditures to keep pace with regulatory initiatives and the rapid technological changes in the financial services market;
the availability of and access to capital;
legislative, regulatory or accounting changes that may adversely affect us;
volatility in the allowance for credit losses resulting from the Current Expected Credit Loss (“CECL”) methodology, either alone or as that may be affected by conditions arising out of the COVID-19 pandemic;
adverse results (including judgments, costs, fines, reputational harm, inability to obtain necessary approvals and/or other negative effects) from current or future litigation, regulatory proceedings, examinations, investigations, or similar matters, or developments related thereto;
3


any matter that would cause us to conclude that there was impairment of any asset, including intangible assets;
limitations on our ability to make dividends and other distributions from the Bank to the Holding Company, which could affect Holding Company liquidity, including the ability to pay dividends to shareholders or take other capital actions;
other risks and uncertainties disclosed in documents filed or furnished by us with or to the SEC, any of which could cause actual results to differ materially from future results expressed, implied or otherwise anticipated by such forward-looking statements.

We caution readers that the foregoing list of factors is not exclusive, is not necessarily in order of importance and not to place undue reliance on forward-looking statements. Additional factors that may cause actual results to differ materially from those contemplated by any forward-looking statements also may be found in our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) and available at the SEC’s website at http://www.sec.gov. We do not intend to and hereby disclaim any obligation to update or revise any forward-looking statement contained in this Form 10-Q, which speak only as of the date hereof, whether as a result of new information, future events, or otherwise. The financial statements and information contained herein have not been reviewed, or confirmed for accuracy or relevance, by the Federal Deposit Insurance Corporation (the “FDIC”) or any other regulator.
