Investor Presentation | Second Quarter 2024 2 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. 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 conditions of the United States economy in general and the strength of the local economies in which we conduct operations; the impact of any future federal government shutdown and uncertainty regarding the federal government’s debt limit or changes in trade, monetary and fiscal policies and laws, including interest rate policies of the Board of Governors of the Federal Reserve System; the impacts of inflation, interest rate, market and monetary fluctuations on the Company's business condition and financial operating results; the impact of changes in financial services industry policies, laws and regulations; regulatory restrictions affecting our ability to successfully market and price our products to consumers; the risks related to the development, implementation, use and management of emerging technologies, including artificial intelligence and machine learning; extreme weather, natural disasters and other catastrophic events that may or may not be caused by climate change and their effects on the Company's customers and the economic and business environments in which the Company operates; the impact of a slowing U.S. economy, decreases in housing and commercial real estate prices, and potentially increased unemployment on the performance of our loan portfolio, the market value of our investment securities and possible other-than-temporary impairment of securities held by us due to changes in credit quality or rates; the availability of, and cost of, sources of funding and the demand for our products; adverse developments with respect to U.S. or global economic conditions and other uncertainties, including the impact of supply chain disruptions, commodities prices, inflationary pressures and labor shortages on the economic recovery and our business; the impacts of international hostilities, wars, terrorism or geopolitical events; adverse developments in the financial services industry generally such as the recent bank failures and any related impact on depositor behavior or investor sentiment; risks related to the sufficiency of liquidity; the possibility that our recorded goodwill could become impaired, which may have an adverse impact on our earnings and capital; the costs or effects of mergers, acquisitions or dispositions we may make, as well as whether we are able to obtain any required governmental approvals in connection with any such activities, or identify and complete favorable transactions in the future, and/or realize the anticipated financial and business benefits; the regulatory and financial impacts associated with exceeding $10 billion in total assets; the negative impact on our reputation and profitability in the event customers experience economic harm or in the event that regulatory violations are identified; the ability to execute our business plan in new markets; the future operating or financial performance of the Company, including our outlook for future growth and changes in the level and direction of our nonperforming assets and charge-offs; the appropriateness of the allowance for credit losses, including the assumptions made under our current expected credit losses model; any deterioration in values of California real estate, both residential and commercial; the effectiveness of the Company's asset management activities managing the mix of earning assets and in improving, resolving or liquidating lower-quality assets; the effect of changes in the financial performance and/or condition of our borrowers; changes in accounting standards and practices; changes in consumer spending, borrowing and savings habits; our ability to attract and maintain deposits and other sources of liquidity; the effects of changes in the level or cost of checking or savings account deposits on our funding costs and net interest margin; increasing noninterest expense and its impact on our financial performance; competition and innovation with respect to financial products and services by banks, financial institutions and non-traditional competitors including retail businesses and technology companies; the challenges of attracting, integrating and retaining key employees; the vulnerability of the Company's operational or security systems or infrastructure, the systems of third-party vendors or other service providers with whom the Company contracts, and the Company's customers to unauthorized access, computer viruses, phishing schemes, spam attacks, human error, natural disasters, power loss and data/security breaches and the cost to defend against and respond to such incidents; the impact of the 2023 cyber security ransomware incident on our operations and reputation; increased data security risks due to work from home arrangements and email vulnerability; failure to safeguard personal information, and any resulting litigation; the effect of a fall in stock market prices on our brokerage and wealth management businesses; the transition from the LIBOR to new interest rate benchmarks; the emergence or continuation of widespread health emergencies or pandemics; the Company’s potential judgments, orders, settlements, penalties, fines and reputational damage resulting from pending or future litigation and regulatory investigations, proceedings and enforcement actions; and our ability to manage the risks involved in the foregoing. There can be no assurance that future developments affecting us will be the same as those anticipated by management. 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, 2023, which has been filed with the Securities and Exchange Commission (the “SEC”) and all subsequent filings with the SEC under Sections 13(a), 13(c), 14, and 15(d) of the Securities Act of 1934, as amended.
