In all cases, interested parties should conduct their own investigation and analysis of the Company and the data set forth in this presentation and other information provided by or on behalf of BCML.

In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change. There are a number of important factors that could cause future results to differ materially from historical performance and these forward-looking statements. Factors which could cause actual results to differ materially from the results anticipated or implied by our forward-looking statements include, but are not limited to, the effect of the COVID-19 pandemic on the Company’s credit quality and business operations, as well as its impact on general economic and financial market conditions and other uncertainties resulting from the COVID-19 pandemic, such as the extent and duration of the impact on public health, the U.S. and global economies, and consumer and corporate clients, including economic activity, employment levels and market liquidity; future acquisitions by the Company of other depository institutions or lines of business; fluctuations in interest rates; the risks of lending and investing activities, including changes in the level and direction of loan delinquencies and write-offs and changes in estimates of the adequacy of the allowance for loan losses; the Company's abili ty to access cost-effective funding; fluctuations in real estate values and both residential and commercial real estate market conditions; demand for loans and deposits in the Company's market area; increased competitive pressures; changes in management’s business strategies; and other factors described in the Company’s latest Annual Report on Form 10-K and Quarterly Reports on Form 10-Q and other filings with the Securities and Exchange Commission (“SEC”) that are available on our website at www.unitedbusinessbank.comand on the SEC's website at www.sec.gov.

3 Further, statements about the potential effects of the proposed acquisition of Pacific Enterprise Bancorp (“PEB”) on our business, financial results, and condition may constitute forward-looking statements and are subject to the risk that the actual effects may differ, possibly materially, from what is reflected in the forward-looking statements due to factors and future developments which are uncertain, unpredictable and in many cases beyond our control, including the possibility that expected revenues, cost savings, synergies and other benefits from the proposed merger might not be realized within the expected time frames or at all including but not limited to customer and employee retention, and costs or difficulties relating to integration matters, might be greater than expected including as a result of changes in general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which BayCom and PEB operate; the possibility that the proposed merger does not close when expected or at all because required regulatory, shareholder or other approvals, financial tests or other conditions to closing are not received or satisfied on a timely basis or at all; the risk that the benefits from the proposed merger may not be fully realized or may take longer to realize than expected or be more costly to achieve; the failure to attract new customers and retain existing customers in the manner anticipated; reputational risks and the potential adverse reactions or changes to business, customer or employee relationships, including those resulting from the announcement or completion of the proposed merger; BayCom’s or PEB’s businesses may experience disruptions due to transaction-related uncertainty or other factors making it more difficult to maintain relationships with employees, customers, other business partners or governmental entities; deposit attrition, operating costs, customer loss and business disruption following the transaction, including difficulties in maintaining relationships with employees, may be greater than expected; the diversion of managements' attention from ongoing business operations and opportunities as a result of the proposed merger or otherwise; changes in BayCom’s or PEB’s stock price before closing, including as a result of its financial performance prior to closing or transaction-related uncertainty, or more generally due to broader stock market movements, and the performance of financial companies and peer group companies; the occurrence of any event, change or other circumstance that could give risk to the right of one or both of the parties to terminate the merger agreement; the outcome of pending or threatened litigation, or of matters before regulatory agencies, whether currently existing or commencing in the future, including litigation related to the merger; changes in interest rates which may affect BayCom’s and PEB’s expected revenues, credit quality deterioration, reductions in real estate values, or reductions in BayCom’s and PEB’s net income, cash flows or the market value of assets, including its investment securities; each of BayCom’s and PEB’s potential exposure to unknown or contingent liabilities of the other party; dilution caused by BayCom’s issuance of additional shares of BayCom common stock in connection with the proposed merger; the possibility that the proposed merger is more expensive to complete than anticipated, including as a result of unexpected factors or events; future acquisitions by BayCom of other depository institutions or lines of business; and that the COVID-19 pandemic, including uncertainty and volatility in financial, commodities and other markets, and disruptions to banking and other financial activity, could harm BayCom’s or PEB’s business, financial position and results of operations, and could adversely affect the timing and anticipated benefits of the proposed merger. The factors listed above could materially affect the Company’s financial performance and could cause the Company’s actual results for future periods to differ materially from any opinions or statements expressed with respect to future periods in any current statements. The Company does not undertake - and specifically declines any obligation - to publicly release the result of any revisions, which may be made to any forward- looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events whether as a result of new information, future events or otherwise, except as may be required by law or NASDAQ rules. When considering forward-looking statements, you should keep in mind these risks and uncertainties. You should not place undue reliance on any forward-looking statement, which speaks only as of the date made.

4 Additional Information about the Proposed Merger and Where to Find It. This presentation does not constitute an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any vote or approval. Investors and security holders are urged to carefully review the Company’s public filings with the SEC, including but not limited to its Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, proxy statements and Current Reports on Form 8-K. The documents are filed with the SEC and may be obtained free of charge at www.sec.gov, and at the Company’s website at www.unitedbusinessbank.com under the tab “Investor Information” and then under the “Documents” link, or writing the Company at 500 Ygnacio Valley Road, Suite 200, Walnut Creek, California, 94596, Attention: Agnes Chiu. ln connection with the proposed merger transaction, the Company filed with the SEC a registration statement on Form S-4 that includes a joint proxy statement of BayCom Corp and PEB, and a prospectus of BayCom Corp, which are referred to as the joint proxy statement/prospectus, as well as other relevant documents concerning the proposed transaction. Before making any voting or investment decision, investors and security holders are urged to carefully read the entire registration statement and joint proxy statement/prospectus, as well as any amendments or supplements to these documents, because they contain important information about the proposed transaction. A definitive joint proxy statement/prospectus will be sent to the shareholders of BayCom Corp and PEB seeking required shareholder approvals. Investors and security holders will be able to obtain the registration statement and the joint proxy statement/ prospectus, and any other documents BayCom Corp files with the SEC free of charge as described in the preceding paragraph. The Company, PEB and certain of their respective directors and executive officers may be deemed to be participants in the solicitation of proxies from the shareholders of BayCom and PEB in connection with the proposed transaction. Information about the Company’s participants may be found in the definitive proxy statement of the Company filed with the SEC on April 29, 2021, and information about PEB’s participants and additional information regarding the interests of these participants is included in the joint proxy statement/prospectus regarding the proposed transaction. 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 “Tangible Book Value Per Share,” and “Tangible Common Equity.” The Company believes that these non-GAAP financial measures are important to many investors who are interested in changes from period to period in book value per common share exclusive of changes in intangible assets. These non-GAAP financial measures are supplemental and are not a substitute for any analysis based on GAAP financial measures. Because not all companies use the same calculation of “Tangible Book Value Per Share,” and “Tangible Common Equity,” this presentation may not be comparable to other similarly titled measures as calculated by other companies.
