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. 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 we conduct operations; the effects of, and changes in, our ability to attract and retain deposits and access to other sources of liquidity, 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; risks and uncertainties related to our adoption of the SOFR family of interest rates to replace LIBOR; 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, including any impairment that may result from increasing volatility in our stock price; the impact of 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; the possibility that we may reduce or discontinue the payments of dividends on our common stock; the possibility that we may discontinue, reduce or limit repurchases of 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, including the war between Russia and Ukraine, 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; climate change, including regulatory, compliance and credit and reputational risks; cybersecurity threats and the cost of defending against them, including compliance costs; natural disasters, earthquakes, fires and severe weather; 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 2021 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
