Transformational Strategic Merger Forming Central California’s Preeminent Community Bank October 10, 2023 Investor Presentation

2 Disclaimer Forward Looking Statements This communication press release contains certain forward-looking information about Central Valley Bancshares (“CVCY”), Community West Bancshares (“CWBC”), and the combined company after the close of the merger and is intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact are forward-looking statements. Such statements involve inherent risks, uncertainties, and contingencies, many of which are difficult to predict and are generally beyond the control of CVCY, CWBC and the combined company. CVCY and CWBC 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. In addition to factors previously disclosed in reports filed by CVCY and CWBC with the Securities and Exchange Commission (“SEC”), risks and uncertainties for each institution and the combined institution include, but are not limited to lower than expected revenues, credit quality deterioration or a reduction in real estate values could cause an increase in the provision for credit losses and allowance for credit losses and a reduction in net earnings, increased competitive pressure among depository institutions, the possibility that changes in the interest rate environment may reduce net interest margins, higher than anticipated operating expenses, the effectiveness of our risk management framework, asset/liability repricing risks and liquidity risks, the ability to complete the merger; government approval may not be obtained or adverse regulatory conditions may be imposed in connection with governmental approvals of the merger; approval by the shareholders of CVCY and CWBC may not be obtained; the successful integration of CWBC, or achieving expected beneficial synergies and/or operating efficiencies, in each case might not be obtained within expected time-frames or at all; the possibility that personnel changes/retention will not proceed as planned; and other risk factors described in documents filed by CVCY and CWBC with the SEC. All forward-looking statements included in this communication are based on information available at the time of the communication. Pro forma, projected and estimated numbers are used for illustrative purposes only and are not forecasts, and actual results may differ materially. We are under no obligation to (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. Use of Non-GAAP Financial Measures This presentation contains certain financial information determined by methods other than in accordance with accounting principles generally accepted in the United States (“GAAP”). These non-GAAP financial measures include “Core Deposits” and “Tangible Common Equity Ratio.” CVCY believes that these non-GAAP financial measures provide both management and investors a more completed understanding of CVCY’s deposit profile and capital. These non-GAAP financial measures are supplemental and are not substitute for any analysis based on GAAP financial measures. Because not all companies use the same calculation of “Core Deposits” and “Tangible Common Equity Ratio,” this presentation may not be comparable to other similarly titled measures as calculated by other companies.
