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 costs and effects of litigation generally, including legal fees and other expenses, settlements and judgments; (ii) the effect of the novel coronavirus (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; (iii) the risk that the benefits we realize from exiting the third party mortgage origination and brokered single-family residential lending business will be less than anticipated and that the costs we incur from exiting that business will be greater than anticipated; (iv) the risk that we will not be successful in the implementation of our capital utilization strategy and our other strategies for transitioning to a traditional community bank; (v) 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; (vi) 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 and lease delinquencies, losses and nonperforming assets in our loan and lease portfolio, and may result in our allowance for credit losses not being adequate and require us to materially increase our loan and lease loss reserves; (vii) the quality and composition of our securities portfolio; (viii) changes in general economic conditions, either nationally or in our market areas, or changes in financial markets; (ix) 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; (x) fluctuations in the demand for loans, and fluctuations in commercial and residential real estate values in our market area; (xi) our ability to develop and maintain a strong core deposit base or other low cost funding sources necessary to fund our activities; (xii) 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 or 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; (xiii) 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; (xiv) our ability to control operating costs and expenses; (xv) staffing fluctuations in response to product demand or the implementation of corporate strategies that affect our work force and potential associated charges; (xvi) the risk that our enterprise risk management framework may not be effective in mitigating risk and reducing the potential for losses; (xvii) errors in estimates of the fair values of certain of our assets and liabilities, which may result in significant changes in valuation; (xviii) 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; (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 severe weather, natural disasters, pandemics, acts of war or terrorism and other external events on our business; (xxiii) the ability of key third-party providers to perform their obligations to us; (xxiv) 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 methods; (xxv) continuing impact of the new accounting standard adopted by the Financial Accounting Standards Board, 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 or preferred stock; and (xxviii) other economic, competitive, governmental, regulatory, and technological factors affecting our operations, pricing, products and services and the other risks described from time to time in other documents that we file with or furnish to the SEC.

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 noninterest expense to average assets, pre-tax pre-provision income, pre-tax pre-provision return on average assets, noninterest expense from core operations, operating expense from core operations, adjusted pre-tax pre-provision income, adjusted pre-tax pre-provision return on average assets, and diluted earnings per common share from core operations, adjusted for non-core items, each excluding loss on investments in alternative energy partnerships and the latter four measurements adjusted for non-core items. Management believes that these particular measures provide useful supplemental information in understanding our core operating performance. These measures should not be viewed as substitutes for measures determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP measures that may be presented by other companies. Reconciliations of these measures to measures determined in accordance with GAAP are contained on slides 43-47 of this presentation. Non-GAAP measures in this presentation also include tangible equity to tangible assets, tangible common equity to tangible assets, return on average tangible common equity, and adjusted efficiency ratio including the pre-tax effect of investments in alternative energy partnerships. These particular measures are used by management in its analysis of the Company's capital strength and the performance of the Company’s businesses. Banking and financial institution regulators also exclude goodwill and other intangible assets from total stockholders' equity when assessing the capital adequacy of a financial institution. Management believes the presentation of these measures excluding the impact of these items provides useful supplemental information that is essential to a proper understanding of the capital and financial strength of the Company and the performance of its businesses. These measures should not be viewed as substitutes for results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP measures that may be presented by other companies. Reconciliations of these measures to measures determined in accordance with GAAP are contained on slides 43-47 of this presentation.
