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. Factors that could cause future results to vary materially from current management expectations include, but are not limited to, general economic conditions and the economic uncertainty in the United States and abroad, including economic or other disruptions to financial markets caused by acts of terrorism, war, impacts from inflation, supply chain disruptions, changes in interest rates (including the actions taken by the Federal Reserve to control inflation), California's unemployment rate, deposit flows, real estate values, and expected future cash flows on loans and securities; the impact of adverse developments at other banks, including bank failures, that impact general sentiment regarding the stability and liquidity of banks; costs or effects of acquisitions; competition; changes in accounting principles, policies or guidelines; changes in legislation or regulation; 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; and successful integration of acquisitions. These and other important factors detailed in various securities law filings made periodically by Bancorp, copies of which are available from us at no charge. Forward-looking statements speak only as of the date they are made. Bancorp undertakes no obligation to release publicly the result of any revisions to these forward-looking statements that may be made to reflect events or circumstances that occur after the date of this press release or to reflect the occurrence of unanticipated events. GAAP to Non-GAAP Financial Measures This presentation includes some non-GAAP financial measures as shown in the Appendix of this presentation. Please refer to the reconciliation of GAAP to Non-GAAP financial measures included in our Form 8-K under Item 9 - Financial Statements and Exhibit 99.1 filed with the SEC on October 28, 2024.

Linked- month cost of deposits reduced by 5 bps in September • Over time, we expect these cuts to offset declines in yields of floating rate assets • Our practice is to use conservative modeled beta assumptions relative to actuals for both rising and falling environments, and we make adjustments as needed to reflect repricing expectations Net Interest Margin Drivers 2.52% 0.03% (0.08)% 0.25% (0.03)% 0.01% 2.70% 2Q24 Loans Securities Cash Deposits Borrowings 3Q24 Net Interest Margin Linked-Quarter Change 2.03% 2.11% 2.24% 2.39% 2.47% 2.50% 2.51% 2.58% 2.60% 2.64% 2.67% 2.59% 5.33% 5.33% 5.33% 5.33% 5.33% 5.33% 5.33% 5.33% 5.33% 5.33% 5.33% 5.13% IB Deposits Fed Funds 10/23 11/23 12/23 1/24 2/24 3/24 4/24 5/24 6/24 7/24 8/24 9/24 Average Monthly Cost of IB Deposits vs. Fed Funds
