2 Nasdaq: BMRC Forward-Looking Statements This discussion of financial results includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, (the "1933 Act") and Section 21E of the Securities Exchange Act of 1934, as amended, (the "1934 Act"). Those sections of the 1933 Act and 1934 Act provide a "safe harbor" for forward-looking statements to encourage companies to provide prospective information about their financial performance so long as they provide meaningful, cautionary statements identifying important factors that could cause actual results to differ significantly from projected results. Our forward-looking statements include descriptions of plans or objectives of management for future operations, products or services, and forecasts of revenues, earnings or other measures of economic performance. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts. They often include the words "believe," "expect," "intend," "estimate" or words of similar meaning, or future or conditional verbs preceded by "will," "would," "should," "could" or "may." Forward-looking statements are based on management's current expectations regarding economic, legislative, and regulatory issues that may affect our earnings in future periods. A number of factors, many of which are beyond management’s control, could cause future results to vary materially from current management expectations. Such factors include, but are not limited to, general economic conditions and the economic uncertainty in the United States and abroad, including changes interest rates, California unemployment rate, deposit flows, real estate values, and expected future cash flows on loans and securities; costs or effects of acquisitions; competition; changes in accounting principles, policies or guidelines; changes in legislation or regulation (including the Coronavirus Aid, Relief and Economic Security Act of 2020, as amended, and the Economic Aid to Hard-Hit Small Businesses, Nonprofits and Venues Act of 2020); our borrowers’ actual payment performance as loan deferrals related to the COVID-19 pandemic expire, including the potential adverse impact of loan modifications and payment deferrals implemented consistent with recent regulatory guidance; natural disasters (such as wildfires and earthquakes in our area); adverse weather conditions; interruptions of utility service in our markets for sustained periods; and other economic, competitive, governmental, regulatory and technological factors (including external fraud and cybersecurity threats) affecting our operations, pricing, products and services. In addition, events or factors that could cause results or performance to materially differ from those expressed in the forward-looking statements concerning the AMRB acquisition include, but are not limited to: • the businesses of Bancorp and AMRB may not be integrated successfully or such integration may be more difficult, time-consuming or costly than expected; • expected cost savings from the acquisition may not be fully realized or realized within the expected time frame; • revenues following the merger may be lower than expected; • customer and employee relationships and business operations may be disrupted by the acquisition; and • the ability to obtain required regulatory and shareholder approvals, and the ability to complete the acquisition within the expected timeframe may be more difficult, time-consuming or costly than expected. Important factors that could cause results or performance to materially differ from those expressed in our prior forward-looking statements are detailed in the Risk Factors section of our 2020 Form 10-K as filed with the SEC, copies of which are available from us at no charge. We do not undertake to update forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements are made or to reflect the occurrence of unanticipated events. GAAP to Non-GAAP Financial Measures This presentation includes some non-GAAP financial measures as shown on page 12 of this presentation. Please refer to the reconciliation of GAAP to Non-GAAP financial measures included on page 2 and 3 of our Form 8-K under Item 9 - Financial Statements and Exhibit 99.1 filed with the SEC on January 24, 2022.
