2© 2022 Pacific Premier Bancorp, Inc. | All rights reserved FORWARD LOOKING STATEMENTS AND WHERE TO FIND MORE INFORMATION Forward Looking Statements This investor presentation contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 regarding the financial condition, results of operations, business plans and the future performance of Pacific Premier Bancorp, Inc. (“PPBI” or the “Company”), including its wholly-owned subsidiary Pacific Premier Bank (“Pacific Premier” or the “Bank”). Words such as “anticipates,” “believes,” “estimates,” “expects,” “forecasts,” “intends,” “plans,” “projects,” “could,” “may,” “should,” “will” or other similar words and expressions are intended to identify these forward-looking statements. These forward-looking statements are based on PPBI’s current expectations and beliefs concerning future developments and their potential effects on the Company including, without limitation, plans, strategies and goals, and statements about the Company’s expectations regarding revenue and asset growth, financial performance and profitability, loan and deposit growth, yields and returns, loan diversification and credit management, stockholder value creation, capital management, tax rates and acquisitions we have made or may make. Because forward-looking statements relate to future results and occurrences, they are subject to inherent uncertainties, risks, and changes in circumstances that are difficult to predict. Many possible events or factors could affect PPBI’s future financial results and performance and could cause actual results or performance to differ materially from anticipated results or performance. Given the ongoing and dynamic nature of the COVID-19 pandemic, the ultimate extent of the impacts on our business, financial position, results of operations, liquidity and prospects remain uncertain. Although general business and economic conditions have recovered considerably, the recovery could be slowed or reversed by a number of factors, including increases in COVID-19 infections, increases in unemployment rates or other labor market disruptions, or turbulence in domestic or global financial markets, which could adversely affect our revenues and the values of our assets and liabilities, reduce the availability of funding, lead to a tightening of credit, and further increase stock price volatility. Increased volatility in our stock price could result in impairment to our goodwill in future periods. In addition, changes to statutes, regulations, or regulatory policies or practices as a result of, or in response to COVID-19, could affect us in substantial and unpredictable ways, including the potential adverse impact of loan modifications and payment deferrals implemented consistent with recent regulatory guidance. Other risks and uncertainties include, but are not limited to, the following: the strength of the United States economy in general and the strength of the local economies in which we conduct operations; the effects of, and changes in, trade, monetary and fiscal policies and laws, including interest rate policies of the Board of Governors of the Federal Reserve System; inflation/deflation, interest rate, market and monetary fluctuations; the effect of acquisitions we have made or may make, including, without limitation, the failure to achieve the expected revenue growth and/or expense savings from such acquisitions, and/or the failure to effectively integrate an acquisition target into our operations; the timely development of competitive new products and services and the acceptance of these products and services by new and existing customers; the impact of changes in financial services policies, laws and regulations, including those concerning taxes, banking, securities and insurance, and the application thereof by regulatory bodies; the effectiveness of our risk management framework and quantitative models; changes in the level of our nonperforming assets and charge-offs; uncertainty regarding the future of LIBOR and potential alternative reference rates, including SOFR; the effect of changes in accounting policies and practices or accounting standards, as may be adopted from time-to-time by bank regulatory agencies, the U.S. Securities and Exchange Commission (“SEC”), the Public Company Accounting Oversight Board, the Financial Accounting Standards Board or other accounting standards setters, including ASU 2016-13 (Topic 326), “Measurement of Credit Losses on Financial Instruments,” commonly referenced as the CECL model, which has changed how we estimate credit losses and may further increase the required level of our allowance for credit losses in future periods; possible credit related impairments of securities held by us; possible impairment charges to goodwill; the impact of current governmental efforts to restructure the U.S. financial regulatory system, including any amendments to the Dodd-Frank Wall Street Reform and Consumer Protection Act; changes in consumer spending, borrowing and savings habits; the effects of our lack of a diversified loan portfolio, including the risks of geographic and industry concentrations; our ability to attract deposits and other sources of liquidity; the possibility that we may reduce or discontinue the payments of dividends on our common stock; changes in the financial performance and/or condition of our borrowers; changes in the competitive environment among financial and bank holding companies and other financial service providers; geopolitical conditions, including acts or threats of terrorism, actions taken by the United States or other governments in response to acts or threats of terrorism and/or military conflicts, which could impact business and economic conditions in the United States and abroad; public health crises and pandemics, including the COVID-19 pandemic, and their effects on the economic and business environments in which we operate, including on our credit quality and business operations, as well as the impact on general economic and financial market conditions; cybersecurity threats and the cost of defending against them, including the costs of compliance with potential legislation to combat cybersecurity at a state, national or global level; unanticipated regulatory or legal proceedings; and our ability to manage the risks involved in the foregoing. Additional factors that could cause actual results to differ materially from those expressed in the forward-looking statements are discussed in the Company's 2020 Annual Report on Form 10-K and other filings filed with the SEC and available at the SEC’s Internet site (http://www.sec.gov). The Company undertakes no obligation to revise or publicly release any revision or update to these forward-looking statements to reflect events or circumstances that occur after the date on which such statements were made. Non-U.S. GAAP Financial Measures This presentation contains non-U.S. GAAP financial measures. For purposes of Regulation G promulgated by the SEC, a non-U.S. GAAP financial measure is a numerical measure of the registrant’s historical or future financial performance, financial position or cash flows that excludes amounts or is subject to adjustments that have the effect of excluding amounts that are included in the most directly comparable measure calculated and presented in accordance with U.S. GAAP in the statement of income, statement of financial condition or statement of cash flows (or equivalent statements) of the issuer; or includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measure so calculated and presented in this regard. U.S. GAAP refers to generally accepted accounting principles in the United States.

34© 2022 Pacific Premier Bancorp, Inc. | All rights reserved NON-U.S. GAAP FINANCIAL MEASURES Note: All dollars in thousands, except per share data Tangible common equity to tangible assets (the "tangible common equity ratio") and tangible book value per share are non-U.S. GAAP financial measures derived from U.S. GAAP-based amounts. We calculate the tangible common equity ratio by excluding the balance of intangible assets from common stockholders' equity and dividing by tangible assets. We calculate tangible book value per share by dividing tangible common equity by common shares outstanding, as compared to book value per common share, which we calculate by dividing common stockholders’ equity by common shares outstanding. We believe that this information is consistent with the treatment by bank regulatory agencies, which exclude intangible assets from the calculation of risk-based capital ratios. Accordingly, we believe that these non-U.S. GAAP financial measures provide information that is important to investors and that is useful in understanding our capital position and ratios. However, these non-U.S. GAAP financial measures are supplemental and are not a substitute for an analysis based on U.S. GAAP measures. As other companies may use different calculations for these measures, this presentation may not be comparable to other similarly titled measures reported by other companies.

38© 2022 Pacific Premier Bancorp, Inc. | All rights reserved NON-U.S. GAAP FINANCIAL MEASURES Core net interest income and core net interest margin are non-U.S. GAAP financial measures derived from U.S. GAAP-based amounts. We calculate core net interest income by excluding scheduled accretion income, accelerated accretion income, premium amortization on CD and nonrecurring nonaccrual interest paid from net interest income. The core net interest margin is calculated as the ratio of core net interest income to average interest-earning assets. Management believes that the exclusion of such items from this financial measure provides useful information to gain an understanding of the operating results of our core business. Core loan interest income and core loan yields are non-U.S. GAAP financial measures derived from U.S. GAAP-based amounts. We calculate core loan interest income by excluding scheduled accretion income, accelerated accretion income and nonrecurring nonaccrual interest paid from loan interest income. The core loan yield is calculated as the ratio of core loan interest income to average loans. Management believes that the exclusion of such items from this financial measure provides useful information to gain an understanding of the operating results of our core business.
