SAFE HARBOR STATEMENT The statements contained herein that are not historical facts are forward-looking statements based on management’s current expectations and beliefs concerning future developments and their potential effects on the Company. Such statements involve inherent risks and uncertainties, many of which are difficult to predict and are generally beyond our control. There can be no assurance that future developments affecting us will be the same as those anticipated by management. We caution readers that a number of important factors could cause actual results to differ materially from those expressed in, or implied or projected by, such forward-looking statements. These risks and uncertainties include, but are not limited to, the following: the strength of the United States economy in general and the strength of the local economies in which we conduct operations; the effects of, and changes in, trade, monetary and fiscal policies and laws, including interest rate policies of the Board of Governors of the Federal Reserve System; inflation, interest rate, market and monetary fluctuations; the impact of changes in financial services policies, laws and regulations; technological changes; weather, natural disasters and other catastrophic events that may or may not be caused by climate change and their effects on economic and business environments in which the Company operates; the adverse impact on the U.S. economy, including the markets in which we operate, of the novel coronavirus, which causes the Coronavirus disease 2019 (“COVID-19”), global pandemic, and the impact of a slowing U.S. economy and increased unemployment on the performance of our loan portfolio, the market value of our investment securities, the availability of sources of funding and the demand for our products; the costs or effects of mergers, acquisitions or dispositions we may make; the future operating or financial performance of the Company, including our outlook for future growth, changes in the level of our nonperforming assets and charge-offs; the appropriateness of the allowance for credit losses including the timing and effects of the implementation of the current expected credit losses model; any deterioration in values of California real estate, both residential and commercial; the effect of changes in accounting standards and practices; possible other-than-temporary impairment of securities held by us; changes in consumer spending, borrowing and savings habits; our ability to attract deposits and other sources of liquidity; changes in the financial performance and/or condition of our borrowers; our noninterest expense and the efficiency ratio; competition and innovation with respect to financial products and services by banks, financial institutions and non-traditional providers including retail businesses and technology companies; the challenges of integrating and retaining key employees; the costs and effects of litigation and of unexpected or adverse outcomes in such litigation; a failure in or breach of our operational or security systems or infrastructure, or those of our third-party vendors or other service providers, including as a result of cyber-attacks and the cost to defend against such attacks; the effect of a fall in stock market prices on our brokerage and wealth management businesses; and our ability to manage the risks involved in the foregoing. Additional factors that could cause results to differ materially from those described above can be found in our Annual Report on Form 10-K for the year ended December 31, 2019, which is on file with the Securities and Exchange Commission (the “SEC”) and available in the “Investor Relations” section of our website, https://www.tcbk.com/investor-relations and in other documents we file with the SEC.
