Prospective investors are cautioned that any such forward-looking statements are not guarantees of future performance and involve known and unknown risks and uncertainties. Factors that might cause such differences include, but are not limited to: the impact of current and future economic conditions, particularly those affecting the financial services industry, including the effects of declines in the real estate market, tariffs or trade wars (including the resulting reduced consumer spending, lower economic growth or recession, reduced demand for U.S. exports, disruptions to supply chains, and decreased demand for other banking products and services), high unemployment rates, inflationary pressures, changes in interest rates (including the impact of prolonged elevated interest rates on our financial projections and models) and slowdowns in economic growth, as well as the financial stress on borrowers as a result of the foregoing; the risk of reductions in benchmark interest rates and the resulting impacts on net interest income; potential impacts of adverse developments in the banking industry highlighted by high-profile bank failures, including impacts on customer confidence, deposit outflows, liquidity and the regulatory response thereto; risks arising from media coverage of the banking industry; risks arising from perceived instability in the banking sector; the risks of changes in interest rates and their effects on the level, cost, and composition of, and competition for, deposits, loan demand and timing of payments, the values of loan collateral, securities, and interest sensitive assets and liabilities; the ability to attract new or retain existing deposits, to retain or grow loans or additional interest and fee income, or to control noninterest expense; the effect of pricing pressures on the Company’s net interest margin; the failure of assumptions underlying the establishment of reserves for possible credit losses, fair value for loans and other real estate owned; changes in real estate values; the Company’s ability to implement its various strategic and growth initiatives; increased competition in the financial services industry, particularly from regional and national institutions, as well as from fintech companies; economic conditions, either nationally or locally, in areas in which the Company conducts operations being less favorable than expected; changes in the prices, values and sales volumes of residential and commercial real estate; developments in our mortgage banking business, including loan modifications, general demand, and the effects of judicial or regulatory requirements or guidance; legislation or regulatory changes which adversely affect the ability of the consolidated Company to conduct business combinations or new operations; adverse results from current or future litigation, regulatory examinations or other legal and/or regulatory actions, including as a result of the Company's participation in and execution of government programs; significant turbulence or a disruption in the capital or financial markets and the effect of a fall in stock market prices on our investment securities; the effects of war or other conflicts; general risks related to the Company’s merger and acquisition activity, including risks associated with integrating and realizing the expected financial benefits of previous acquisitions, and the Company’s pursuit of future acquisitions; the impact of generative artificial intelligence; fraud or misconduct by internal or external actors, and system failures, cybersecurity threats or security breaches and the cost of defending against them; a deterioration of the credit rating for U.S. long-term sovereign debt, actions that the U.S. government may take to avoid exceeding the debt ceiling, and uncertainties surrounding debt ceiling and the federal budget; a potential U.S. federal government shutdown and the resulting impacts; and general competitive, economic, political and market conditions or other unexpected factors or events. These and other factors, risks and uncertainties could cause the actual results, performance or achievements of the Company to be materially different from the future results, performance or achievements expressed or implied by such forward-looking statements. Many of these factors are beyond the Company’s ability to control or predict. Forward-looking statements speak only as of the date on which such statements are made.
