 Forward-Looking Statements This communication contains certain forward-looking information about PacWest Bancorp that is intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995. Statements that are not historical or current facts, including statements about future financial and operational results, expectations, or intentions are forward-looking statements. Such statements are based on information available at the time of the communication and are based on current beliefs and expectations of the Company’s management and are subject to significant risks, uncertainties and contingencies, many of which are beyond our control. The COVID-19 pandemic is adversely affecting PacWest Bancorp, its employees, customers and third-party service providers, and the ultimate extent of the impacts on its business, financial position, results of operations, liquidity and prospects is uncertain. The length of the COVID-19 pandemic and the severity of its impact on key macro-economic indicators such as unemployment and GDP may have a material impact on our allowance for credit losses and related provision for credit losses. Continued deterioration in general business and economic conditions could adversely affect PacWest Bancorp’s revenues and the values of its assets and liabilities, including goodwill, lead to a tightening of credit and increase stock price volatility. In addition, PacWest Bancorp’s results could be adversely affected by changes in interest rates, sustained high unemployment rates, deterioration in the credit quality of its loan portfolio or in the value of the collateral securing those loans, deterioration in the value of its investment securities and legal and regulatory developments. Actual results may differ materially from those set forth or implied in the forward-looking statements due to a variety of factors, including the risk factors described in documents filed by the Company with the U.S. Securities and Exchange Commission. We are under no obligation (and expressly disclaim any such obligation) to update or alter our forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.
