Concluding Thoughts Appendix

Pro Forma Capital Ratios Actual as of 6/30/2015 Based on merger assumptions for Security acquisition as identified on slides 5 and 6 Non-GAAP, please see GAAP reconciliation PPBI (1) Pro Forma (2) Tangible Common Equity Ratio (3) 8.65% 8.50% Leverage Ratio 8.98% 8.86% Common Equity Tier-1 Ratio (CET-1) 9.81% 10.01% Tier-1 Ratio 10.12% 10.26% Risk Based Capital Ratio 13.40% 12.94%

Non-GAAP Financial Measures Tangible common equity to tangible assets (the "tangible common equity ratio") and tangible book value per share are a non-GAAP financial measures derived from 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-GAAP financial measures provide information that is important to investors and that is useful in understanding our capital position and ratios. However, these non-GAAP financial measures are supplemental and are not a substitute for an analysis based on 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-GAAP measure of tangible common equity ratio to the GAAP measure of common equity ratio and tangible book value per share to the GAAP measure of book value per share are set forth below.
