2 FORWARD LOOKING STATEMENTS When used in this report and in documents filed with or furnished to the Securities and Exchange Commission (the “SEC”), in press releases or other public stockholder communications, or in oral statements made with the approval of an authorized executive officer, the words or phrases “believe,” “will,” “should,” “will likely result,” “are expected to,” “will continue,” “is anticipated,” “estimate,” “project,” “plans,” or similar expressions are intended to identify “forward-looking statements” within the meaning of the “Safe-Harbor” provisions of the Private Securities Litigation Reform Act of 1995. You are cautioned not to place undue reliance on any forward-looking statements. These statements may relate to future financial performance, strategic plans or objectives, revenue, expense or earnings projections, or other financial items of Banc of California, Inc. and its affiliates (“BANC,” the “Company”, “we”, “us” or “our”), as well as the continuing effects of the COVID-19 pandemic on the Company’s business, operations, financial performance and prospects. By their nature, these statements are subject to numerous uncertainties that could cause actual results to differ materially from those anticipated in the statements. Factors that could cause actual results to differ materially from the results anticipated or projected include, but are not limited to, the following: (i) the effect of the COVID-19 pandemic and steps taken by governmental and other authorities to contain, mitigate, and combat the pandemic on our business, operations, financial performance and prospects; (ii) the costs and effects of litigation generally, including legal fees and other expenses, settlements and judgments; (iii) the risk that we will not be successful in the implementation of our capital utilization strategy, new lines of business, new products and services, or other strategic project initiatives; (iv) risks that the Company’s merger and acquisition transactions may disrupt current plans and operations and lead to difficulties in customer and employee retention, risks that the costs, fees, expenses and charges related to these transactions could be significantly higher than anticipated and risks that the expected revenues, cost savings, synergies, and other benefits of these transactions might not be realized to the extent anticipated, within the anticipated timetables, or at all; (v) the credit risks of lending activities, which may be affected by deterioration in real estate markets and the financial condition of borrowers, and the operational risk of lending activities, including but not limited to, the effectiveness of our underwriting practices and the risk of fraud, any of which may lead to increased loan delinquencies, losses, and nonperforming assets in our loan portfolio, and may result in our allowance for credit losses not being adequate and require us to materially increase our credit loss reserves; (vi) the quality and composition of our securities portfolio; (vii) changes in general economic conditions, either nationally or in our market areas, or changes in financial markets; (viii) continuation of, or changes in, the short-term interest rate environment, changes in the levels of general interest rates, volatility in the interest rate environment, the relative differences between short- and long-term interest rates, deposit interest rates, our net interest margin, and funding sources; (ix) fluctuations in the demand for loans, and fluctuations in commercial and residential real estate values in our market area; (x) our ability to develop and maintain a strong core deposit base or other low cost funding sources necessary to fund our activities; (xi) results of examinations of us by regulatory authorities and the possibility that any such regulatory authority may, among other things, limit our business activities, require us to change our business mix, restrict our ability to invest in certain assets, increase our allowance for credit losses, write-down asset values, increase our capital levels, affect our ability to borrow funds or maintain or increase deposits, or impose fines, penalties or sanctions, any of which could adversely affect our liquidity and earnings; (xii) legislative or regulatory changes that adversely affect our business, including, without limitation, changes in tax laws and policies, changes in privacy laws, and changes in regulatory capital or other rules, and the availability of resources to address or respond to such changes; (xiii) our ability to control operating costs and expenses; (xiv) staffing fluctuations in response to product demand or the implementation of corporate strategies that affect our work force and potential associated charges; (xv) the risk that our enterprise risk management framework may not be effective in mitigating risk and reducing the potential for losses; (xvi) errors in estimates of the fair values of certain of our assets and liabilities, which may result in significant changes in valuation; (xvii) failures or security breaches with respect to the network and computer systems on which we depend, including but not limited to, due to cybersecurity threats; (xviii) our ability to attract and retain key members of our senior management team; (xix) increased competitive pressures among financial services companies; (xx) changes in consumer spending, borrowing and saving habits; (xxi) the effects of severe weather, including as a result of climate change, natural disasters, pandemics, acts of war or terrorism, and other external events on our business; (xxii) the ability of key third-party providers to perform their obligations to us; (xxiii) changes in accounting policies and practices, as may be adopted by the financial institution regulatory agencies or the Financial Accounting Standards Board or their application to our business, including additional guidance and interpretation on accounting issues and details of the implementation of new accounting standards; (xxiv) continuing impact of the Financial Accounting Standards Board’s credit loss accounting standard, referred to as Current Expected Credit Loss, which requires financial institutions to determine periodic estimates of lifetime expected credit losses on loans, and provide for the expected credit losses as allowances for loan losses; (xxv) share price volatility and reputational risks, related to, among other things, speculative trading and certain traders shorting our common shares and attempting to generate negative publicity about us; (xxvi) our ability to obtain regulatory approvals or non-objection to take various capital actions, including the payment of dividends by us or our bank subsidiary, or repurchases of our common or preferred stock; and (xxvii) other economic, competitive, governmental, regulatory, and technological factors affecting our operations, pricing, products and services and the other risks described in this report and from time to time in other documents that we file with or furnish to the SEC. Further, statements about the potential effects of the Pacific Mercantile Bancorp acquisition 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 those forward-looking statements due to factors and future developments that are uncertain, unpredictable and in many cases beyond our control, including (i) the risk that the benefits from the transaction may not be fully realized or may take longer to realize 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 Banc of California, Inc. and Pacific Mercantile Bancorp operate; (ii) the ability to promptly and effectively integrate the businesses of Banc of California, Inc. and Pacific Mercantile Bancorp; (iii) diversion of management time on integration-related issues; (iv) lower than expected revenues, credit quality deterioration or a reduction in real estate values or a reduction in net earnings; and (v) other risks that are described in Banc of California, Inc.’s public filings with the SEC.

14 ALLOWANCE FOR CREDIT LOSSES WALK 4Q21: The ACL reserve increased $19.4 million due to: (1) a $13.7 million initial allowance for credit losses established for purchased credit-deteriorated ("PCD") loans from the PMB Acquisition, (2) an $11.3 million initial charge for all other loans acquired from PMB, and (3) higher specific reserves of $1.3 million, offset by (4) net charge-offs of $5.5 million and (5) lower general reserves of $1.3 million from portfolio mix. ACL includes Allowance for Loan Losses (ALL) and Reserve for Unfunded Loan Commitments (RUC) – Our ACL methodology uses a nationally recognized, third-party model that includes many assumptions based on historical and peer loss data, current loan portfolio risk profile including risk ratings, and economic forecasts including macroeconomic variables (MEVs) released by our model provider during December 2021. The December 2021 forecasts reflect a consistent view of the economy as compared to the September 2021 forecasts. While the current forecasts generally reflect an improving economy with the availability of the vaccine and other factors, there continues to be uncertainty regarding the impact of inflation (lasting or transitory), COVID-19 variants, further government stimulus, supply chain issues, and the ultimate pace of economic recovery. Accordingly, the economic assumptions used in the model and the resulting ACL level and provision consider both the positive assumptions and potential uncertainties.

32 NON-GAAP FINANCIAL INFORMATION This presentation contains certain financial measures determined by methods other than in accordance with U.S. generally accepted accounting principles (GAAP). These measures include tangible assets, tangible equity, tangible common equity, tangible equity to tangible assets, tangible common equity to tangible assets, tangible common equity per common share, return on average tangible common equity, adjusted noninterest income, adjusted noninterest expense, adjusted noninterest expense to average total assets, pre-tax pre-provision (PTPP) income (loss), adjusted PTPP income (loss), PTPP income (loss) ROAA, adjusted PTPP income (loss) ROAA, efficiency ratio, adjusted efficiency ratio, adjusted total revenue, adjusted net income, adjusted net income available to common stockholders, adjusted diluted earnings per share (EPS) and adjusted return on average assets (ROAA) constitute supplemental financial information determined by methods other than in accordance with GAAP. These non-GAAP measures are used by management in its analysis of the Company's performance. Tangible assets and tangible equity are calculated by subtracting goodwill and other intangible assets from total assets and total equity. Tangible common equity is calculated by subtracting preferred stock from tangible equity. Return on average tangible common equity is computed by dividing net income (loss) available to common stockholders, adjusted for amortization of intangible assets, by average tangible common equity. Banking regulators also exclude goodwill and other intangible assets from stockholders' equity when assessing the capital adequacy of a financial institution. PTPP income is calculated by adding net interest income and noninterest income (total revenue) and subtracting noninterest expense. Adjusted PTPP income is calculated by adding net interest income and adjusted noninterest income (adjusted total revenue) and subtracting adjusted noninterest expense. PTPP income ROAA is computed by dividing annualized PTPP income by average assets. Adjusted PTPP income ROAA is computed by dividing annualized adjusted PTPP income by average assets. Efficiency ratio is computed by dividing noninterest expense by total revenue. Adjusted efficiency ratio is computed by dividing adjusted noninterest expense by adjusted total revenue. Adjusted net income (loss) is calculated by adjusting net income (loss) for tax-effected noninterest income and expense adjustments and the tax impact from the exercise of stock appreciation rights. Adjusted ROAA is computed by dividing annualized adjusted net income by average assets. Adjusted net income (loss) available to common shareholders is computed by removing the impact of preferred stock redemptions from adjusted net income (loss). Management believes the presentation of these financial measures adjusting the impact of these items provides useful supplemental information that is essential to a proper understanding of the financial results and operating performance of the Company. This disclosure should not be viewed as a substitute for results determined in accordance with GAAP, nor is it necessarily comparable to non-GAAP performance measures that may be presented by other companies.
