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”). 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 continuing effects 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, 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 and, in the case of our recent acquisition of Deepstack Technologies, reputational risk, regulatory risk and potential adverse reactions of the Company's or Deepstack's customers, suppliers, vendors, employees or other business partners; (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, including the impact of supply chain disruptions, or changes in financial markets, and the risk of recession or an economic downtrun;

(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, result in write-downs of 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) uncertainty regarding the expected discontinuation of the London Interbank Offered Rate (“LIBOR”) and the use of alternative reference rates; (xviii) failures or security breaches with respect to the network, applications, vendors and computer systems on which we depend, including but not limited to, due to cybersecurity threats; (xix) our ability to attract and retain key members of our senior management team; (xx) increased competitive pressures among financial services companies; (xxi) changes in consumer spending, borrowing and saving habits; (xxii) the effects of climate change, severe weather events, natural disasters, pandemics, epidemics and other public health crises, acts of war or terrorism, and other external events on our business;

(xxv) 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; (xxvi) 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; (xxvii) 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 stock;

27 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 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 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, after adjustment 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 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 expense adjustments and the tax impact from the exercise of stock appreciation rights for the periods indicated. Adjusted net income is calculated by adjusting net income for tax-effected noninterest income and noninterest expense adjustments and the tax impact from the exercise of stock appreciation rights for the periods indicated. Adjusted ROAA is computed by dividing annualized adjusted net income by average assets. Adjusted net income (loss) available to common stockholders is computed by removing the impact of preferred stock redemptions from adjusted net income (loss). Adjusted diluted earnings per share is computed by dividing adjusted net income (loss) available to common stockholders by the weighted average diluted common shares outstanding. 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. Reconciliations of these measures to measures determined in accordance with GAAP are contained on slides 28-32 of this presentation.
