The statements contained in this presentation that are not historical facts are forward-looking statements based on management’s current expectations and beliefs concerning future developments and their potential effects on Pacific Premier Bancorp, Inc. (“PPBI”) including, without limitation, plans, strategies and goals, and statements about PPBI’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 and the impact of PPBI’s acquisitions. Such statements involve inherent risks and uncertainties, many of which are difficult to predict and are generally beyond the control of PPBI. There can be no assurance that future developments affecting PPBI will be the same as those anticipated by management. PPBI cautions readers that a number of important factors could cause actual results to differ materially from those expressed in, or implied or projected by, such forward-looking statements. These 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 PPBI conducts 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 may make, such as our recent acquisition of Grandpoint Capital Inc., 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 PPBI’s nonperforming assets and charge offs; the effect of changes in accounting policies and practices, as may be adopted from time-to-time by bank regulatory agencies, the Securities and Exchange Commission (“SEC”), the Public Company Accounting Oversight Board, the Financial Accounting Standards Board or other accounting standards setters; possible other-than-temporary impairment of securities held by us; 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 PPBI’s 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; 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 judicial proceedings; and PPBI’s 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 2018 Annual Report on Form 10-K of Pacific Premier Bancorp, Inc. filed with the SEC and available at the SEC’s Internet site (http://www.sec.gov). Annualized, pro forma, projected and estimated numbers in this investor presentation are used for illustrative purposes only, are not forecasts and may not reflect actual results. PPBI 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. PRELIMINARY RESULTS AS OF AND FOR THE THREE MONTHS ENDED MARCH 31, 2019 This presentation contains PPBI’s preliminary results as of and for the three months ended March 31, 2019. PPBI has not filed its Quarterly Report on Form 10-Q for the quarter ended March 31, 2019. As a result all financial results as of and for the three months ended March 31, 2019 described herein should be considered preliminary and are subject to change to reflect any changes resulting from the completion of normal quarter-end closing and review procedures. PPBI’s actual results may differ materially from these estimates due to the completion of financial closing procedures, final adjustments and other developments that may arise between the date of this presentation and the time PPBI files its Quarterly Report on Form 10-Q.

For the periods presented below, operating net income and operating diluted earnings per share are non-U.S. GAAP financial measures derived from U.S. GAAP-based amounts. We calculate these figures by excluding merger related expenses and DTA revaluations in the period results. Management believes that the exclusion of such items from these financial measures provides useful information to an understanding of the operating results of our core business. For the quarter period presented below, adjusted net income for return on average tangible common equity and average tangible common equity are non-U.S. GAAP financial measures derived from U.S. GAAP-based amounts. We calculate return on average tangible common equity by adjusting net income for the effect of CDI amortization and exclude the average CDI and average goodwill from the average stockholders' equity during the period. We calculate adjusted return on average tangible common equity by adjusting net income for the effect of CDI amortization and merger related expense and exclude the average CDI and average goodwill from the average stockholders' equity during the period. We believe that this 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 adjusted measures, this presentation may not be comparable to other similarly titled adjusted measures reported by other companies. A reconciliation of the non-U.S. GAAP measures of return on average tangible common equity and adjusted return on average tangible common equity to the U.S. GAAP measure of return on common stockholders’ equity is set forth below.

For the periods presented below, adjusted noninterest expense and adjusted revenue are non-U.S. GAAP financial measures derived from U.S. GAAP-based amounts. Efficiency ratio is a non-GAAP measure that represents the ratio of noninterest expense less other real estate owned operations, core deposit intangible amortization and merger related and litigation expenses, to the sum of net interest income before provision for loan losses and total noninterest income less gain (loss) on sale of securities, gain (loss) on sale of other real estate owned, other-than-temporary impairment recovery (loss) on investment securities, and gain on acquisitions. Management believes that the exclusion of such items from these financial measures provides useful information to an understanding of the operating results of our core business. 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 adjusted measures, this presentation may not be comparable to other similarly titled adjusted measures reported by other companies. A reconciliation of the non-U.S. GAAP measure of efficiency ratio to the U.S. GAAP measure of efficiency ratio is set forth below.
