FORWARD-LOOKING STATEMENTS

Statements contained in this Quarterly Report on Form 10-Q that are not historical facts are forward-looking statements (as defined in the Private Securities Litigation Reform Act of 1995). In addition, First US Bancshares, Inc. (“Bancshares” and, together with its subsidiary, the “Company”), through its senior management, from time to time makes forward-looking statements concerning its expected future operations, performance and other developments. The words “estimate,” “project,” “intend,” “anticipate,” “expect,” “believe,” “continues” and similar expressions are indicative of forward-looking statements. Such forward-looking statements are necessarily estimates reflecting the Company’s best judgment based on current information and involve a number of risks and uncertainties. Certain factors that could affect the accuracy of such forward-looking statements and cause actual results to differ materially from those projected in such forward-looking statements are identified in the Company’s filings with the Securities and Exchange Commission (the “SEC”), and forward-looking statements contained herein or in other public statements of the Company or its senior management should be considered in light of those factors. Such factors may include adverse developments in the financial services industry; loan losses may be greater than anticipated; our ability to ensure that sufficient cash flow and liquid assets are available to satisfy current and future financial obligations; the increased lending risks associated with commercial real estate lending; potential weakness in the residential real estate market; liquidity risks; the impact of national and local market conditions on the Company’s business and operations; the rate of growth (or lack thereof) in the economy generally and in the Company’s service areas; the effects of significant changes to the structure and operations of the federal government; strong competition in the banking industry; the impact of changes in interest rates and monetary policy on the Company’s performance and financial condition; the effects of fiscal challenges facing the U.S. government or any potential government shutdown; effects of changes in the policies of monetary authorities and other government action; the impact of technological changes in the banking and financial service industries and potential information system failures; cybersecurity and data privacy threats; the risks and challenges presented by the development and use of artificial intelligence (“AI”); risks of dependence on outside third parties for the processing and handling of our records and data; the costs of complying with extensive governmental regulation; the risk that internal controls and procedures might fail or be circumvented; the impact of changing accounting standards and tax laws on the Company’s financial results; the potential impact of climate change and related legislative and regulatory initiatives; the possibility that acquisitions may not produce anticipated results and result in unforeseen integration difficulties; the volatility of our stock price and our dependence on the soundness of other financial institutions; and other risk factors described from time to time in the Company’s public filings, including, but not limited to, the Company’s most recent Annual Report on Form 10-K. Relative to the Company’s dividend policy, the payment of cash dividends is subject to the discretion of the Board of Directors and will be determined in light of then-current conditions, including the Company’s earnings, leverage, operations, financial conditions, capital requirements and other factors deemed relevant by the Board of Directors. In the future, the Board of Directors may change the Company’s dividend policy, including the frequency or amount of any dividend, in light of then-existing conditions.
