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 and Opus's current expectations and assumptions regarding PPBI's and Opus's businesses, the economy, and other future conditions. 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 or Opus's future financial results and performance and could cause actual results or performance to differ materially from anticipated results or performance. Such risks and uncertainties include, among others: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the definitive agreement and plan of reorganization by and among PPBI, Pacific Premier and Opus, the outcome of any legal proceedings that may be instituted against PPBI or Opus, delays in completing the transaction, the failure to obtain necessary regulatory approvals (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the transaction) and shareholder approvals or to satisfy any of the other conditions to the transaction on a timely basis or at all, the possibility that the anticipated benefits of the transaction are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where PPBI and Opus do business, the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events, diversion of management's attention from ongoing business operations and opportunities, potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the transaction, the ability to complete the transaction and integration of Pacific Premier and Opus successfully, and the dilution caused by PPBI's issuance of additional shares of its capital stock in connection with the transaction. Except to the extent required by applicable law or regulation, each of PPBI and Opus disclaims any obligation to update such factors or to publicly announce the results of any revisions to any of the forward-looking statements included herein to reflect future events or developments.

Appendix

NON-U.S. GAAP

FINANCIAL MEASURES

Tangible common equity to tangible assets (the "tangible common equity ratio") and tangible book value per share are a 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. A reconciliation of the non-U.S. GAAP measure of tangible common equity ratio to the U.S. GAAP measure of common equity ratio and tangible book value per share to the U.S. GAAP measure of book value per share are set forth below.
