Dear Pacific Premier Bancorp Shareholders:

          On December 12, 2016, Pacific Premier Bancorp, Inc., which we refer to as Pacific Premier, entered into an agreement and plan of reorganization, which we refer to as the merger agreement, to acquire Heritage Oaks Bancorp, which we refer to as HEOP. If the required shareholder and regulatory approvals are obtained, all closing conditions are satisfied or waived and the merger is subsequently completed, HEOP will be merged with and into Pacific Premier, with Pacific Premier as the surviving entity, which we refer to as the merger. Immediately thereafter, HEOP's wholly-owned bank subsidiary, Heritage Oaks Bank, will be merged with and into Pacific Premier Bank, the wholly-owned bank subsidiary of Pacific Premier, with Pacific Premier Bank as the surviving entity.

          You are cordially invited to attend a special meeting of shareholders of Pacific Premier, to be held at              a.m., Pacific Time, on                         , 2017 at 17901 Von Karman Avenue, Suite 1200, Irvine, California 92614. At the Pacific Premier special meeting, the Pacific Premier shareholders will be asked to consider and vote upon a proposal to approve the issuance of shares of Pacific Premier common stock in connection with the merger. HEOP will also hold a special meeting of shareholders to consider the proposed merger agreement and related matters. Pacific Premier and HEOP cannot complete the proposed merger unless Pacific Premier's shareholders vote to approve the issuance of shares of Pacific Premier common stock in connection with the merger. This letter is accompanied by the attached joint proxy statement/prospectus, which Pacific Premier's board of directors is providing to solicit your proxy to vote for the approval of the issuance of shares of Pacific Premier common stock in connection with the merger.

          If the required shareholder and regulatory approvals are obtained and the merger is subsequently completed, upon effectiveness of the merger, each outstanding share of HEOP common stock will be cancelled and converted into the right to receive 0.3471 shares of Pacific Premier common stock, which we refer to as the merger consideration. Cash will be paid in lieu of any fractional share interest. The term aggregate merger consideration refers to the total consideration to be paid by Pacific Premier to the HEOP shareholders in the merger, not including holders of (i) options to purchase shares of HEOP common stock, (ii) restricted shares of HEOP common stock, or (iii) restricted stock units of HEOP.

          The implied value of the merger consideration to be paid to HEOP shareholders is based on an exchange ratio of 0.3471 shares of Pacific Premier common stock for each share of HEOP common stock. The implied value per share of HEOP common stock on                         , 2017 was $            , which amount was based on the closing price per share of Pacific Premier common stock on that date. The value of the merger consideration will fluctuate based on the market price of Pacific Premier common stock. Consequently, the value of the merger consideration will not be known at the time you vote on the issuance of shares of Pacific Premier common stock in connection with the merger. Pacific Premier's common stock is listed on the NASDAQ Global Select Market under the symbol "PPBI." You should obtain current market quotations for the Pacific Premier common stock.

          Based on our reasons for the merger described in the accompanying document, including the fairness opinion issued by our financial advisor, D.A. Davidson & Co., our board of directors believes that the issuance of shares of Pacific Premier common stock in connection with the merger is fair to the Pacific Premier shareholders and in your best interests. Accordingly, our board of directors unanimously recommends that you vote "FOR" the issuance of shares of Pacific Premier common stock in connection with the merger. The accompanying joint proxy statement/prospectus gives you detailed information about the Pacific Premier special meeting, the merger and the issuance of shares of Pacific Premier common stock in connection with the merger and related matters. In addition to being a proxy statement of Pacific Premier, this document is the proxy statement for the solicitation of proxies from HEOP shareholders to vote to approve the merger agreement and is the prospectus of Pacific Premier for the shares of its common stock that will be issued to HEOP shareholders in connection with the merger.

          We advise you to read this entire document carefully, including the considerations discussed under "Risk Factors" beginning on page 32, and the appendices to the accompanying joint proxy statement/prospectus, which include the merger agreement.

          Your vote is very important. The merger cannot be completed unless the holders of a majority of the shares for which votes are cast at the Pacific Premier special meeting vote in favor of approval of the issuance of shares of Pacific Premier common stock in connection with the merger. Whether or not you plan to attend the Pacific Premier special meeting, please take the time to vote by completing and mailing the enclosed proxy card or by following the instructions to vote via the Internet or by telephone indicated on the proxy card.

          We appreciate your continuing loyalty and support and, should you choose to attend, we look forward to seeing you at the Pacific Premier special meeting.

  Sincerely,

Pacific Premier and HEOP have entered into an agreement and plan of reorganization, which we refer to as the merger agreement, pursuant to which Pacific Premier would acquire HEOP. If the required shareholder and regulatory approvals are obtained and the merger is subsequently completed, HEOP will be merged with and into Pacific Premier with Pacific Premier as the surviving entity. Immediately thereafter, HEOP's wholly-owned bank subsidiary, Heritage Oaks Bank, will be merged with and into Pacific Premier Bank, the wholly-owned bank subsidiary of Pacific Premier, with Pacific Premier Bank as the surviving entity.

Q:
Will HEOP shareholders be able to trade the Pacific Premier common stock that they receive in the merger?

A:
Yes. The Pacific Premier common stock issued in the merger to HEOP shareholders will be listed on the NASDAQ Global Select Market under the symbol "PPBI." Unless you are deemed an "affiliate" of Pacific Premier, you may sell the shares of Pacific Premier common stock you receive in the merger without restriction.

Q:
Why is my vote important?

A:
The merger agreement must be approved by the holders of a majority of the outstanding shares of HEOP common stock. The issuance of the Pacific Premier common stock in connection with the merger must be approved by the holders of Pacific Premier common stock constituting at least a majority of the shares for which votes are cast at the Pacific Premier special meeting. The merger cannot be completed unless the Pacific Premier shareholders approve the issuance of Pacific Premier common stock in the merger and HEOP shareholders approve the merger agreement. The Pacific Premier shareholders will vote on the applicable proposals necessary to complete the merger at the Pacific Premier special meeting and the HEOP shareholders will vote on the applicable proposals necessary to complete the merger at the HEOP special meeting. Information about the Pacific Premier special meeting and the HEOP special meeting, the merger and the other business to be considered by shareholders at each of the special meetings is contained in this document.
Q:
Why must the Pacific Premier shareholders approve the issuance of shares of Pacific Premier common stock in connection with the merger?

A:
The Pacific Premier shareholders are required to approve the issuance of shares of the Pacific Premier common stock, which is estimated to equate to approximately       % of Pacific Premier's issued and outstanding shares of common stock, in connection with the merger because Pacific Premier is listed on the NASDAQ Global Select Market and is subject to the NASDAQ Global Select Market listing rules. Because Pacific Premier will likely issue in excess of 20% of its outstanding shares of common stock to the HEOP shareholders in connection with the merger, under the NASDAQ Global Select Market listing rules, the shareholders of Pacific Premier are required to approve the issuance of shares of Pacific Premier common stock in connection with the merger. The merger cannot be completed unless the Pacific Premier shareholders approve the issuance of shares of Pacific Premier common stock in the merger.

Q:
What do each of the Pacific Premier and the HEOP boards of directors recommend?

A:
The Pacific Premier board of directors unanimously recommends that Pacific Premier shareholders vote "FOR" approval of the issuance of Pacific Premier common stock in connection with the merger and "FOR" approval of the proposal to adjourn the special meeting, if necessary, to solicit additional proxies in favor of the issuance of Pacific Premier common stock in connection with the merger.

A:
Yes. Set forth under the heading of "Risk Factors," beginning on page 32, are a number of risk factors that each of the shareholders of Pacific Premier and HEOP should consider carefully.

Q:
When do Pacific Premier and HEOP expect to complete the merger?

A:
The parties expect to complete the merger either by the end of the first quarter of 2017 or early in the second quarter of 2017. However, there is no assurance when or if the merger will occur. Prior to the consummation of the merger, HEOP shareholders must approve the merger agreement at the HEOP special meeting, Pacific Premier shareholders must approve the issuance of Pacific Premier common stock in connection with the merger at the Pacific Premier special meeting and all requisite bank regulatory approvals must be obtained and other conditions to the consummation of the merger must be satisfied.

A:
If you are a holder of HEOP common stock and you abstain from voting or fail to instruct your bank, broker or other nominee to vote your shares and the bank, broker or other nominee submits an unvoted proxy, referred to as a broker non-vote, then the abstention or broker non-vote will be counted towards a quorum at the special meeting, but it will have the same effect as a vote against approval of the merger agreement.

A:
Yes. While not required to, all Pacific Premier shareholders are invited to attend the Pacific Premier special meeting. Likewise, all HEOP shareholders are invited to attend the HEOP special meeting.

Q:
Can I change my vote?

The Merger (Page      )

        The merger agreement is attached to this joint proxy statement/prospectus as Appendix A, which is incorporated by reference into this joint proxy statement/prospectus. Please read the entire merger agreement. It is the legal document that governs the merger. Pursuant to the terms and conditions set forth in the merger agreement, HEOP will be acquired by Pacific Premier in a transaction in which HEOP will merge with and into Pacific Premier, with Pacific Premier as the surviving institution. Immediately following the consummation of the merger, Heritage Oaks Bank will be merged with and into Pacific Premier Bank, with Pacific Premier Bank as the surviving institution.

Pacific Premier's Reasons for Merger and Factors Considered by Pacific Premier's Board of Directors (Page      )

        As part of its business strategy, Pacific Premier evaluates opportunities to acquire bank holding companies, banks and other financial institutions, which is an important element of its strategic plan. The acquisition of HEOP is consistent with this strategy. The acquisition of HEOP will (i) extend Pacific Premier's geographic footprint into the Central Coast of California, (ii) create opportunities for Pacific Premier Bank to provide additional products and services to the HEOP customers, and (iii) strengthen Pacific Premier Bank's deposit base with low cost core deposits.

        Based on Pacific Premier's reasons for the merger described in this joint proxy statement/prospectus, including the fairness opinion of D.A. Davidson & Co., or Davidson, an independent investment banking firm, the Pacific Premier board of directors believes that the merger is fair to Pacific Premier's shareholders and in their best interests, and unanimously recommends that Pacific Premier shareholders vote "FOR" approval of the issuance of Pacific Premier common stock in connection with the merger. For a discussion of the circumstances surrounding the merger and the factors considered by Pacific Premier's board of directors in approving the merger agreement, see "The Merger—Pacific Premier's Reasons for the Merger" beginning on page       .

HEOP's Reasons for Merger and Factors Considered by HEOP's Board of Directors (Page      )

        Based on HEOP's reasons for the merger described in this joint proxy statement/prospectus, the HEOP board of directors believes that the merger is fair to HEOP shareholders and in their best interests, and unanimously recommends that HEOP shareholders vote "FOR" approval of the merger agreement. For a discussion of the circumstances surrounding the merger and the factors considered by HEOP's board of directors in approving the merger agreement, see "The Merger—HEOP's Reasons for the Merger" beginning on page       .

Pacific Premier's Financial Advisor Believes that the Merger Consideration Payable by Pacific Premier to HEOP Shareholders in the Merger is Fair, from a Financial Point of View, to Pacific Premier (Page      )

        Davidson delivered its written opinion to Pacific Premier's board of directors that, as of December 12, 2016, and based upon and subject to assumptions made, procedures followed, matters considered and limitations and qualification on the review undertaken set forth in its opinion, the merger consideration to be paid by Pacific Premier to HEOP shareholders in the merger pursuant to the merger agreement was fair, from a financial point of view, to Pacific Premier.

        The full text of the written opinion of Davidson, dated December 12, 2016, which sets forth assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken is attached as Appendix B to this joint proxy statement/prospectus. Pacific Premier's shareholders should read the opinion in its entirety. Davidson provided its opinion for the information and assistance of Pacific Premier's board of directors in connection with its consideration of the transaction. The Davidson opinion does not address the underlying business decision to proceed with the merger and is not a recommendation as to how any holder of Pacific Premier common stock should vote on matters to be considered at the Pacific Premier special meeting.

Opinion of HEOP's Financial Advisor (Page      )

        In connection with the merger, Sandler O'Neill & Partners, L.P., or Sandler O'Neill, delivered its oral opinion to HEOP's board of directors, which was subsequently confirmed in writing on December 11, 2016, to the effect that, as of December 11, 2016, and based upon and subject to the assumptions made, procedures followed, matters considered and limitations and qualification on the review undertaken by Sandler O'Neill in providing its opinion, the exchange ratio was fair, from a financial point of view, to the holders of HEOP common stock.

HEOP's shareholders should read the opinion in its entirety. The opinion of Sandler O'Neill has not been updated prior to the date of this joint proxy statement/prospectus and does not reflect any change in circumstance after December 11, 2016. Sandler O'Neill provided its opinion for the information and assistance of HEOP's board of directors in connection with its consideration of the transaction. The Sandler O'Neill opinion does not address the underlying business decision to proceed with the merger and is not a recommendation as to how any holder of HEOP common stock should vote on matters to be considered at the HEOP special meeting.

HEOP Shareholders Will Receive Shares of Pacific Premier Common Stock for Each Share of HEOP Common Stock Exchanged in the Merger (Page      )

        At the effective time of the merger, each outstanding share of HEOP common stock will, by virtue of the merger and without any action on the part of an HEOP shareholder, be converted into the right to receive 0.3471 shares of Pacific Premier common stock, which is referred to as the exchange ratio. Cash will be paid in lieu of any fractional share interest.

Aggregate Merger Consideration.

        The total consideration to be paid by Pacific Premier to the HEOP shareholders in connection with the merger is referred to in this joint proxy statement/prospectus as the aggregate merger consideration. The term aggregate merger consideration does not include the consideration, if any, payable to holders of (i) options to purchase shares of HEOP common stock, (ii) restricted shares of HEOP common stock, or (iii) restricted stock units of HEOP. In this joint proxy statement/prospectus, we refer to stock options to purchase shares of HEOP's common stock as HEOP options, restricted shares of HEOP common stock as HEOP restricted stock, and restricted stock units as HEOP restricted stock units.

        Upon completion of the merger and based on a $33.65 closing price of Pacific Premier's common stock on December 12, 2016, approximately $401.27 million of aggregate merger consideration will be payable to the HEOP shareholders. The foregoing sentence does not include the payment of cash to the holders of HEOP restricted stock units whose restricted stock units will accelerate in connection with the closing of the merger and assumes that (i) there are 34,355,624 shares of HEOP common

stock outstanding at the closing, (ii) the HEOP shareholders will receive an aggregate of 11,924,837 shares of Pacific Premier common stock after applying the exchange ratio of 0.3471, and (iii) there is no acceleration of vesting of shares of HEOP restricted stock in connection with the closing of the merger that would result in such shares of HEOP restricted stock being converted into the right to receive the merger consideration in the merger.

Fractional Shares.

        No fractional shares of Pacific Premier common stock will be issued, and in lieu thereof, each holder of HEOP common stock who would otherwise be entitled to a fractional share interest will receive an amount in cash, without interest, determined by multiplying such fractional interest by the average closing price per share of Pacific Premier common stock, as reported on the NASDAQ Global Select Market, for the twenty (20) trading days ending on and including the fifth trading day prior to the closing date of the merger, or the Pacific Premier average share price, rounded to the nearest whole cent.

What Will Happen to Outstanding HEOP Options, HEOP Restricted Stock and HEOP Restricted Stock Units (Page      )

HEOP Options.

        Each outstanding and unexercised option to acquire shares of HEOP common stock will be assumed by Pacific Premier and converted automatically into an option to purchase shares of Pacific Premier common stock, which is referred to as a converted HEOP option. The number of shares of Pacific Premier common stock subject to such converted HEOP option shall be equal to the number of shares of HEOP common stock subject to such converted HEOP option immediately prior to the closing of the merger multiplied by the exchange ratio, provided that any fractional shares of Pacific Premier common stock resulting from such multiplication shall be rounded down to the nearest share. The per share exercise price under each such converted HEOP option will be adjusted by dividing the per share exercise price under each such converted HEOP option by the exchange ratio, provided that such exercise price will be rounded up to the nearest cent.

HEOP Restricted Stock Units.

        The board of directors of HEOP intends to accelerate the vesting of HEOP restricted stock units and HEOP restricted stock held by directors, officers and employees of HEOP or its subsidiaries that are not expected to continue with Pacific Premier or its subsidiaries following the closing of the merger.

        Each cash-settled HEOP restricted stock unit which is vested and outstanding as of the closing of the merger will be entitled to receive a single lump sum cash payment equal to the sum of (i) the product of (A) and (B) where (A) equals the product of the number of HEOP restricted stock units and the exchange ratio and (B) equals the average closing price of Pacific Premier common stock during the twenty (20) trading day period ending on the fifth business day prior to the effective time of the merger, which is referred to as the Pacific Premier average share price, plus (ii) any HEOP dividends previously accrued, provided that any fractional HEOP restricted stock units remaining will receive an amount determined by multiplying the fractional share interest by the Pacific Premier average share price, rounded to the nearest whole cent.

        Each unvested cash-settled HEOP restricted stock unit which is outstanding as of the closing of the merger will be assumed by Pacific Premier and will be converted into a right to receive cash payments based upon the values of shares of Pacific Premier common stock. The number of shares of Pacific Premier common stock referenced in each cash-settled HEOP restricted stock unit will be equal to the number of shares of HEOP common stock subject to such cash-settled HEOP restricted stock unit immediately prior to the effective time of the merger multiplied by the exchange ratio, including any fractional shares of Pacific Premier common stock. Any dividends accrued with respect to cash-settled HEOP restricted stock units will continue to be accrued and deferred until such time as the award vests and is paid.

HEOP Restricted Stock.

        Each unvested award of HEOP restricted stock that is outstanding as of the closing of the merger will be assumed by Pacific Premier and converted into shares of Pacific Premier common stock. The number of shares of Pacific Premier common stock subject to each award of HEOP restricted stock will be equal to the number of shares of HEOP common stock subject to such award of HEOP restricted stock immediately prior to the effective time of the merger multiplied by the exchange ratio, provided that any fractional shares of Pacific Premier common stock will be converted into cash in lieu of fractional shares of Pacific Premier common stock. Based on 188,519 shares of unvested HEOP restricted stock, 65,435 shares of Pacific Premier common stock would be issuable to holders of unvested awards of HEOP restricted stock as of that date.

HEOP Performance-Based Restricted Stock Units.

        Pacific Premier will not assume outstanding performance-based HEOP restricted stock units issued for the performance period extending from January 1, 2016 through December 31, 2018. The performance-based HEOP restricted stock units will become vested immediately prior to the effective time of the merger, and each of the holders thereof will be entitled to receive a single lump sum cash payment equal to the product of (A), (B) and (C), where (A) equals 100% of the target number of shares of HEOP common stock subject to the performance-based HEOP restricted stock units, (B) equals the exchange ratio, and (C) equals the Pacific Premier average share price.

Transmittal Materials (Page        )

        After the transmittal materials have been received and processed following the closing of the merger, the HEOP shareholders will be sent the Pacific Premier common stock and any cash in lieu of fractional shares to which they are entitled. If a HEOP shareholder holds shares in street name, he or she will receive information from his or her bank, broker or other nominee advising such HEOP shareholder of the process for receiving the Pacific Premier common stock and any cash in lieu of fractional shares to which he or she is entitled.

        Each HEOP shareholder will need to surrender his or her HEOP common stock certificates or follow instructions for the transfer of shares of HEOP common stock held in book-entry form, to receive the appropriate merger consideration. HEOP shareholders should not send any certificates now. Each HEOP shareholder will receive detailed instructions on how to exchange his or her share certificates or book-entry shares along with transmittal materials promptly following the closing of the merger.

Per Share Market Price and Dividend Information (Page        )

        Shares of Pacific Premier common stock currently trade on the NASDAQ Global Select Market under the symbol "PPBI." Shares of HEOP common stock also trade on the NASDAQ Global Select Market under the symbol "HEOP."

        The following table sets forth the closing sale prices of (i) Pacific Premier common stock as reported on the NASDAQ Global Select Market, and (ii) HEOP common stock as reported on the NASDAQ Global Select Market, on December 12, 2016, the last trading-day before Pacific Premier announced the merger, and on                 , the last practicable trading-day before the distribution of this joint proxy statement/prospectus. To help illustrate the market value of the per share merger consideration to be received by HEOP's shareholders, the following table also presents the equivalent market value per share of HEOP common stock as of December 12, 2016 and                 , which were determined by multiplying the closing price for the Pacific Premier common stock on those dates by the exchange ratio of 0.3471 of a share of Pacific Premier common stock for each share of HEOP common

        The market price of Pacific Premier common stock and HEOP common stock will fluctuate prior to the date of each of Pacific Premier's and HEOP's special meeting and the date such HEOP shareholder receives the merger consideration. HEOP shareholders should obtain a current price quotation for the shares of Pacific Premier common stock to update the implied value for a share of HEOP common stock.

        Pacific Premier has never declared or paid dividends on its common stock and does not anticipate declaring or paying any cash dividends in the foreseeable future. It is Pacific Premier's current policy to retain earnings to provide funds for use in its business.

        HEOP has been paying a regular quarterly dividend on its common stock. Pursuant to the merger agreement, HEOP may continue to pay its regular quarterly cash dividend equal to the rate paid during the fiscal quarter immediately preceding the date of the merger agreement, with record and payment dates consistent with past practice. See "The Merger—Business Pending the Merger" beginning on page        .

Material Federal Income Tax Consequences of the Merger (Page         )

        The merger is intended to qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, which is referred to in this joint proxy statement/prospectus as the Code, and it is a condition to completion of the merger that Pacific Premier and HEOP receive a legal opinion to that effect. If the merger is completed, the merger consideration that will be paid to the holders of HEOP common stock will consist of shares of Pacific Premier common stock (and cash for any fractional shares).

        Assuming the merger qualifies as a reorganization, subject to the limitations and more detailed discussion set forth in "The Merger—Material Federal Income Tax Consequences" of this joint proxy statement/prospectus, a HEOP shareholder that is a U.S. holder generally will not recognize gain or loss on such exchange, other than with respect to cash received in lieu of fractional shares of Pacific Premier common stock.

        Tax matters are complicated, and the tax consequences of the merger to a particular HEOP shareholder will depend in part on such shareholder's individual circumstances. Accordingly, each HEOP shareholder is urged to consult his or her own tax advisor for a full understanding of the tax consequences of the merger to such shareholder, including the applicability and effect of federal, state, local and foreign income and other tax laws.

UNAUDITED CONDENSED PRO FORMA COMBINED
CONSOLIDATED FINANCIAL DATA

        The following Unaudited Condensed Pro Forma Combined Consolidated Statement of Financial Condition as of September 30, 2016 combines the historical Consolidated Statement of Financial Condition of Pacific Premier and the historical Consolidated Balance Sheet of HEOP as of such date (i) on an actual historical basis and (ii) assuming the completion of the merger at such date, using the acquisition method of accounting and giving effect to the related pro forma adjustments described in the accompanying Notes to the Unaudited Condensed Pro Forma Combined Financial Statements.

        The following Unaudited Condensed Pro Forma Combined Consolidated Statements of Operations for both the nine months ended September 30, 2016 and the year ended December 31, 2015 combine the historical Consolidated Statements of Operations of Pacific Premier and the historical Consolidated Statements of Income of HEOP for such respective periods giving effect to the merger as if the merger had become effective at the beginning of the periods presented, using the acquisition method of accounting and giving effect to the pro forma adjustments described in the accompanying Notes to the Unaudited Condensed Pro Forma Combined Financial Statements. The Unaudited Condensed Pro Forma Combined Consolidated Statement of Operations for the nine months ended September 30, 2016 and for the year ended December 31, 2015 also gives effect to Pacific Premier's acquisition of Security California Bancorp, giving effect to the merger as if the merger had become effective at the beginning of the period, using the acquisition method of accounting and giving effect to the pro forma adjustments described in the accompanying Notes to the Unaudited Pro Forma Combined Financial Statements.

        Although pro forma financial information is not a measurement of performance calculated in accordance with GAAP, Pacific Premier and HEOP believe that pro forma financial information is important because it gives effect to the merger and the transactions referenced above. The manner in which Pacific Premier and HEOP calculate pro forma financial information may differ from similarly titled measures reported by other companies.

        The unaudited condensed pro forma combined consolidated financial information included in this joint proxy statement/prospectus are presented for informational purposes only. This information includes various estimates and may not necessarily be indicative of the financial condition or results of operations that would have occurred if the merger or the other transactions referenced above had been completed on the dates or at the beginning of the periods indicated or which may be obtained in the future. The unaudited pro forma combined financial information has been derived from and should be read in conjunction with the respective period's historical consolidated financial statements and the related notes of Pacific Premier and HEOP. The historical consolidated financial statements of Pacific Premier and HEOP are filed with the Commission and incorporated by reference into this joint proxy statement/prospectus. See "Where You Can Find More Information."

        The pro forma information, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the opportunities to earn additional revenue and does not include certain assumptions as to cost savings and, accordingly, does not attempt to predict or suggest future results. It also does not necessarily reflect what the historical results of the combined company would have been had the companies been combined during the periods presented.

        The unaudited condensed pro forma combined consolidated stockholders' equity and net income are qualified by the statements set forth under this caption and should not be considered indicative of the market value of Pacific Premier's common stock or the actual or future results of operations of

Notes to Unaudited Condensed Pro Forma Combined Consolidated Financial Statements

Note A—Basis of Presentation

        The Unaudited Condensed Pro Forma Combined Consolidated Statement of Financial Condition and explanatory notes as of September 30, 2016 combines the historical Consolidated Statement of Financial Condition of Pacific Premier and the historical Consolidated Balance Sheet of HEOP as of such date (i) on an actual historical basis and (ii) assuming the completion of the merger at such date, using the acquisition method of accounting and giving effect to the related pro forma adjustments described in the accompanying Notes to the Unaudited Condensed Pro Forma Combined Consolidated Financial Statements.

        The Unaudited Condensed Pro Forma Combined Consolidated Statements of Operations and explanatory notes for both the nine months ended September 30, 2016 and the year ended December 31, 2015 combine the historical Consolidated Statements of Operations of Pacific Premier and the historical Consolidated Statements of Income of HEOP for such respective periods giving effect to the merger as if the merger had become effective at the beginning of the periods presented, using the acquisition method of accounting and giving effect to the pro forma adjustments described in the accompanying Notes to the Unaudited Condensed Pro Forma Combined Consolidated Financial Statements. The Unaudited Condensed Pro Forma Combined Consolidated Statement of Operations for the nine months ended September 30, 2016 and the year ended December 31, 2015 also gives effect to Pacific Premier's acquisition of Security California Bancorp, giving effect to the merger as if the merger had become effective at the beginning of the period using the acquisition method of accounting and giving effect to the pro forma adjustments described in the accompanying Notes to the Unaudited Pro Forma Combined Financial Statements.

        Since the merger is recorded using the acquisition method of accounting, all loans are recorded at fair value, including adjustments for credit quality, and no allowance for credit losses is carried over to Pacific Premier's balance sheet. In addition, certain anticipated nonrecurring costs associated with the merger such as professional fees, legal fees and conversion-related expenditures are not reflected in the pro forma statements of operations.

        While the recording of the acquired loans at their fair value will impact the prospective determination of the provision for credit losses and the allowance for credit losses, for purposes of the Unaudited Condensed Pro Forma Combined Consolidated Statements of Operations for the nine months ended September 30, 2016 and the year ended December 31, 2015, Pacific Premier assumed no adjustments to the historical amounts of HEOP's and Security California Bancorp's provisions for credit losses. If such adjustments were estimated, there could be an increase or a reduction to the historical amounts of HEOP's and Security California Bancorp's provisions for credit losses presented. In addition, the fair value of the loan portfolio is not necessarily reflective of the allowance for loan losses calculated under the probable incurred loss model, as the fair value also takes into account an interest and liquidity component.

Note B—Accounting Policies and Financial Statement Classifications

        The accounting policies of HEOP are in the process of being reviewed in detail by Pacific Premier. Upon completion of such review, conforming adjustments or financial statement reclassifications may be determined.

Note C—Merger and Acquisition Integration Costs

        In connection with the merger, the plan to integrate Pacific Premier's and HEOP's operations is still being developed. The specific details of this plan will continue to be refined over the next several months, and will include assessing personnel, benefit plans, premises, equipment, and service contracts

to determine where they may take advantage of redundancies. Certain decisions arising from these assessments may involve involuntary termination of employees, vacating leased premises, changing information systems, canceling contracts with certain service providers, and selling or otherwise disposing of certain furniture and equipment. Pacific Premier also expects to incur merger-related costs including professional fees, legal fees, system conversion costs and costs related to communications with customers and others. To the extent there are costs associated with these actions, the costs will be recorded based on the nature of the cost and in the period incurred.

Note D—Estimated Annual Cost Savings

        Pacific Premier expects to realize cost savings following the merger. These cost savings are not reflected in the pro forma financial information and there can be no assurance they will be achieved in the amount or manner currently contemplated.

Note E—Pro Forma Adjustments

        The following pro forma adjustments have been reflected in the unaudited pro forma combined condensed consolidated financial information. All adjustments are based on current assumptions and valuations, which are subject to change.

UNAUDITED COMPARATIVE PER SHARE DATA

        The following table sets forth certain historical, pro forma and pro forma equivalent per share financial information for the Pacific Premier common stock and the HEOP common stock. The pro forma and pro forma equivalent per share information for the nine month period ended September 30, 2016 gives effect to the merger as if the transaction had been effective on the last date of the period, in the case of book value data, and as if the transaction had been effective on the first day of the period, in the case of the income and dividend data. The pro forma and pro forma equivalent per share information for the twelve month period ended December 31, 2015 gives effect to (i) the completion of Pacific Premier's acquisition of Security California Bancorp, which was completed on January 31, 2016 and (ii) the merger as if the transaction had been effective on the last date of the period, in the case of book value data, and as if the transaction had been effective on the first day of the period, in the case of the income and dividend data. The pro forma information in the below table assumes that the merger is accounted for under the acquisition method of accounting. The information in the following table is based on, and should be read together with, the historical consolidated financial information that Pacific Premier and HEOP have presented in their prior filings with the Commission and which are incorporated into this joint proxy statement/prospectus.

RISK FACTORS

        In addition to the other information included and incorporated by reference into this joint proxy statement/prospectus, including the matters addressed in the section entitled "Cautionary Statement Concerning Forward-Looking Statements" beginning on page            , you should be aware of and carefully consider the following risks and uncertainties that are applicable to the merger agreement, the merger, Pacific Premier and HEOP before deciding whether to vote for (i) if you are a Pacific Premier shareholder, the issuance of shares of Pacific Premier common stock to the HEOP shareholders in connection with the merger and the approval of the adjournment of the Pacific Premier special meeting, if necessary, to solicit additional proxies to approve the issuance of shares of Pacific Premier common stock, or (ii) if you are a HEOP shareholder, the approval of the merger agreement and the other transactions contemplated by the merger and the approval of the adjournment of the HEOP special meeting, if necessary, to solicit additional proxies in favor of the proposal to approve the merger and the other transactions contemplated by the merger agreement. You should also consider the risks relating to the businesses of Pacific Premier and ownership of Pacific Premier common stock contained in Part I, Item 1A of Pacific Premier's Annual Report on Form 10-K for the year ended December 31, 2015 that has been filed with the Commission, as well as any subsequent documents filed by Pacific Premier with the Commission, which are incorporated into this joint proxy statement/prospectus by reference. See "Where You Can Find More Information" beginning on page            .

Because the market price of Pacific Premier common stock will fluctuate, the HEOP shareholders cannot be sure of the exact value of the merger consideration they will receive.

        Upon the effective time of the merger, each share of HEOP common stock will be cancelled and converted into the right to receive the merger consideration, consisting of shares of Pacific Premier common stock pursuant to the terms of the merger agreement. The value of the merger consideration to be received by HEOP shareholders will be based on an exchange ratio, which is fixed at 0.3471 shares of Pacific Premier common stock for each share of HEOP common stock. Because the price of Pacific Premier common stock could fluctuate during the period of time between the HEOP special meeting and the time the HEOP shareholders actually receive their shares of Pacific Premier common stock as merger consideration, the HEOP shareholders will be subject to the risk of a decline in the price of Pacific Premier common stock during this period. HEOP does not have the right to terminate the merger agreement or to resolicit the vote of its shareholders solely because of changes in the market prices of Pacific Premier's common stock. Stock price changes may result from a variety of factors, including general market and economic conditions, changes in the values and perceptions of financial services stocks generally and Pacific Premier in particular, changes in Pacific Premier's business, operations and prospects and regulatory considerations. Many of these factors are beyond Pacific Premier's control. Accordingly, at the time of the HEOP special meeting, the HEOP shareholders will not know or be able to calculate the exact value of the shares of Pacific Premier common stock they will receive upon completion of the merger.

Directors and officers of HEOP have interests in the merger that are in addition to or different than the interests of HEOP shareholders.

        HEOP directors and officers have interests in the merger as individuals that are in addition to, or different from, their interests as shareholders of HEOP, which are:

32


Table of Contents

        These arrangements may create potential conflicts of interest. These interests of HEOP's directors and officers may cause some of these persons to view the proposed transaction differently than how other HEOP shareholders view it. The HEOP and Pacific Premier boards of directors were aware of these interests and considered them, among other things, in their approval of the merger agreement and the transactions contemplated by the merger agreement. HEOP shareholders should consider these interests in conjunction with the recommendation of the HEOP board of directors with respect to approval of the merger. See "The Merger—Interests of Certain HEOP Officers and Directors in the Merger" beginning on page            .

The termination fee and the restrictions on solicitation contained in the merger agreement may discourage other companies from trying to acquire HEOP.

        Until the completion of the merger, with some limited exceptions, HEOP is prohibited from soliciting, initiating, encouraging or participating in any discussion of or otherwise considering any inquiries or proposals that may lead to an acquisition proposal, such as a merger or other business combination transaction, with any person other than Pacific Premier. In addition, HEOP has agreed to pay a termination fee to Pacific Premier in specified circumstances. See "The Merger—Termination Fee" beginning on page             . These provisions could discourage other companies from trying to acquire HEOP even though those other companies might be willing to offer greater value to HEOP shareholders than Pacific Premier has offered in the merger. The payment of the termination fee could also have a material adverse effect on HEOP's financial condition.

Table of Contents

Pacific Premier may fail to realize the anticipated benefits of the merger.

        The success of the merger will depend on, among other things, Pacific Premier's ability to realize the anticipated revenue enhancements and efficiencies and to combine the businesses of Pacific Premier and HEOP in a manner that does not materially disrupt the existing customer relationships of HEOP or result in decreased revenues resulting from any loss of customers and that permits growth opportunities to occur. If Pacific Premier is not able to successfully achieve these objectives, the anticipated benefits of the merger may not be realized fully or at all or may take longer to realize than expected.

        Pacific Premier and HEOP have operated and, until the completion of the merger, will continue to operate, independently. It is possible that the integration process could result in the loss of key employees, the disruption of each company's ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect Pacific Premier's ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits of the merger. Integration efforts between the two companies could also divert management attention and resources. These integration matters could have an adverse effect on each of Pacific Premier and HEOP during the transition period and on the combined company following completion of the merger.

The market price of Pacific Premier common stock after the merger may be affected by factors different from those affecting the shares of HEOP or Pacific Premier currently.

        Upon completion of the merger, holders of HEOP common stock will become holders of Pacific Premier common stock. Pacific Premier's business differs from that of HEOP, and, accordingly, the financial condition and results of operations of the combined company and the market price of Pacific Premier common stock after the completion of the merger may be affected by factors different from those currently affecting the financial condition and results of operations of HEOP or Pacific Premier on a standalone basis.

The fairness opinion received by Pacific Premier's board of directors from its financial advisor, Davidson, and the fairness opinion received by HEOP's board of directors from HEOP's financial advisor, Sandler O'Neill, will not be updated to reflect any changes since the date of such opinions.

        Changes in the operations and prospects of Pacific Premier or HEOP, general market and economic conditions and other factors that may be beyond the control of Pacific Premier and HEOP may alter the value of Pacific Premier or HEOP or the market price for shares of Pacific Premier common stock or HEOP common stock by the time the merger is completed. Neither the fairness opinion delivered by Davidson to the Pacific Premier board of directors nor the fairness opinion delivered by Sandler O'Neill to the HEOP board of directors speaks as of any date other than the date of such opinion, which was December 12, 2016 in the case of Davidson's opinion and December 11, 2016 in the case of Sandler O'Neill's opinion. The merger agreement does not require that either Davidson's or Sandler O'Neill's fairness opinion be updated as a condition to the completion of the merger, and neither Pacific Premier nor HEOP intends to request that the respective fairness opinions be updated. Davidson's fairness opinion is attached as Appendix B to this joint proxy statement/prospectus and Sandler O'Neill's fairness opinion is attached as Appendix C to this joint proxy statement/prospectus. For a description of Davidson's opinion, see "The Merger—Opinion of Pacific Premier's Financial Advisor" beginning on page        . For a description of Sandler O'Neill's opinion, see "The Merger—Opinion of HEOP's Financial Advisor" beginning on page        . For a description of the other factors considered by Pacific Premier's board of directors in determining to approve the merger, see "The Merger—Pacific Premier's Reasons for the Merger" beginning on page         . For a description of the other factors considered by HEOP's board of directors in determining to approve the merger, see "The Merger—HEOP's Reasons for the Merger" beginning on page         .

The merger is subject to the receipt of approvals or waivers from regulatory authorities that may impose conditions that could have an adverse effect on Pacific Premier.

        Before the merger can be completed, various approvals or waivers must be obtained from bank regulatory authorities. Regulatory approval or waivers are not guaranteed and even if granted, the bank regulatory authorities may impose conditions on the completion of the merger or require changes to the terms of the merger. Although Pacific Premier and HEOP do not currently expect that any such conditions or changes will be imposed, there can be no assurance that they will not be, and such conditions or changes could have the effect of delaying completion of the merger, imposing additional costs on, or limiting the revenues of Pacific Premier following the merger or causing the merger transaction between Pacific Premier and HEOP to terminate. See "The Merger—Bank Regulatory Approvals" beginning on page            and "The Merger—Conditions to the Merger" beginning on page            .

The merger cannot be completed unless the Pacific Premier shareholders approve the issuance of Pacific Premier common stock in the merger and the HEOP shareholders approve the merger agreement.

        In order for the merger to be completed, the Pacific Premier shareholders must approve the issuance of Pacific Premier common stock in the merger and the HEOP shareholders must approve the merger agreement and the other transactions contemplated by the merger agreement. While a vote of Pacific Premier's shareholders is not required to approve the merger, the approval of Pacific Premier's shareholders is required under applicable NASDAQ rules in order for Pacific Premier to be authorized to issue the shares of Pacific Premier common stock to HEOP shareholders as the merger consideration. Approval of the issuance of Pacific Premier common stock to HEOP stockholders under NASDAQ rules requires approval of at least a majority of the total votes cast at the Pacific Premier special meeting. The approval of the merger agreement by the HEOP shareholders requires the affirmative vote of the holders of a majority of the outstanding shares of HEOP common stock. If either or both of these required votes is not obtained from the shareholders of each of the respective companies, the merger may not be consummated.

The merger is subject to certain closing conditions that, if not satisfied or waived, will result in the merger not being completed, which may cause the prices of Pacific Premier common stock and HEOP common stock to decline.

        Consummation of the merger is subject to customary conditions to closing in addition to the receipt of the required regulatory approvals and approval of the HEOP shareholders of the merger agreement and the approval of the Pacific Premier shareholders of the issuance of Pacific Premier common stock in connection with the merger. If any condition to the merger is not satisfied or waived, to the extent permitted by law, the merger will not be completed. In addition, Pacific Premier and HEOP may terminate the merger agreement under certain circumstances even if the merger agreement is approved by HEOP shareholders and the issuance of Pacific Premier common stock in connection with the merger is approved by Pacific Premier shareholders, including if the merger has not been completed on or before August 30, 2017. If the merger is not completed, the respective trading prices of Pacific Premier common stock and HEOP common stock on the NASDAQ Global Stock Market may decline to the extent that the current prices reflect a market assumption that the merger will be completed. In addition, neither company would realize any of the expected benefits of having completed the merger. For more information on closing conditions to the merger agreement, see "The Merger—Conditions to the Merger" beginning on page            .

The shares of Pacific Premier common stock to be received by HEOP shareholders as a result of the merger will have different rights than shares of HEOP common stock.

        Upon completion of the merger, HEOP shareholders will become Pacific Premier shareholders and their rights as shareholders will be governed by the Pacific Premier amended and restated certificate of incorporation, the Pacific Premier amended and restated bylaws and the DGCL. The rights associated with HEOP common stock are different from the rights associated with Pacific Premier common stock. See "Comparison of the Rights of Shareholders" beginning on page            .

Matters to be Considered

        The purposes of the Pacific Premier special meeting are to:

        No other business may be conducted at the Pacific Premier special meeting. A copy of the merger agreement is included in this joint proxy statement/prospectus as Appendix A, and Pacific Premier shareholders are encouraged to read it carefully in its entirety.

Recommendation of the Pacific Premier Board of Directors

        The Pacific Premier board of directors has unanimously (i) determined that each of the merger agreement and the transactions contemplated by the merger agreement are fair and reasonable, advisable and in the best interests of Pacific Premier and its shareholders; (ii) approved the merger agreement, the merger and the transactions contemplated thereby and (iii) recommends that the Pacific Premier shareholders approve the issuance of shares of Pacific Premier common stock to HEOP shareholders pursuant to the merger agreement. The Pacific Premier board of directors unanimously recommends that Pacific Premier shareholders vote "FOR" the proposal to approve the issuance of shares of Pacific Premier common stock to HEOP shareholders pursuant to the merger agreement. See "The Merger—Pacific Premier's Reasons for the Merger" beginning on page         .

        The Pacific Premier board of directors also unanimously recommends that Pacific Premier shareholders vote "FOR" the proposal to adjourn the Pacific Premier special meeting, if necessary, to permit further solicitation of proxies on the proposal to approve the issuance of shares of Pacific Premier common stock to the HEOP shareholders pursuant to the merger agreement.

How to Vote Pacific Premier Shares

Shareholders of Record.

        Pacific Premier shareholders of record may vote by mail, telephone, via the Internet or by attending the Pacific Premier special meeting and voting in person. If a Pacific Premier shareholder chooses to vote by mail, he or she should simply mark the enclosed proxy card, date and sign it, and return it in the postage-paid envelope provided. Internet and telephone voting is available until 11:59 p.m., Eastern Time, on            .

Shares Held in "Street Name."

        If a Pacific Premier shareholder's shares of Pacific Premier common stock are held through a bank, broker or other nominee, such Pacific Premier shareholder is considered the beneficial owner of such shares held in "street name." In such case, this joint proxy statement/prospectus has been forwarded by such Pacific Premier shareholder's bank, broker or other nominee, who is considered, with respect to such shares, the shareholder of record. As the beneficial owner, a Pacific Premier shareholder has the right to direct such bank, broker or other nominee how to vote the shares by following the voting instructions that they have sent, or will send, to the Pacific Premier shareholder. Without specific instructions from the Pacific Premier shareholder, the bank, broker or other nominee is not empowered to vote a Pacific Premier shareholder's shares on non-routine matters such as the proposal to approve the issuance of shares of common stock of Pacific Premier to the shareholders of HEOP pursuant to the merger agreement or the proposal of the Pacific Premier board of directors to adjourn the Pacific Premier special meeting, if necessary. Not voting these shares will not have any effect on the vote to approve the proposal to issue of shares of common stock of Pacific Premier to the shareholders of HEOP pursuant to the merger agreement or the proposal of the Pacific Premier board of directors to adjourn the special meeting, if necessary. When the vote is tabulated for the proposals, broker non-votes, if any, will only be counted for purposes of determining whether a quorum is present. Accordingly, we advise each Pacific Premier shareholder to promptly give instructions to his or her bank, broker or other nominee to vote "FOR" approval of the issuance of shares of Pacific Premier common stock to the HEOP shareholders pursuant to the merger agreement and "FOR" the proposal to adjourn the Pacific Premier special meeting, if necessary, by using the voting instruction card provided to such Pacific Premier shareholder by his or her bank, broker or other nominee. Alternatively, if a Pacific Premier shareholder is a beneficial owner and wishes to vote in person at the Pacific Premier special meeting, the Pacific Premier shareholder must provide a proxy executed in such Pacific Premier shareholder's favor by the bank, broker or other nominee.

Revocation of Proxies

        A Pacific Premier shareholder can revoke a proxy at any time before his or her shares are voted. If the Pacific Premier shareholder is a shareholder of record, the Pacific Premier shareholder can revoke a proxy by:

41


Table of Contents

        If a Pacific Premier shareholder has instructed a bank, broker or other nominee to vote such Pacific Premier shareholder's shares of Pacific Premier common stock, the Pacific Premier shareholder must follow directions received from the bank, broker or other nominee to change his or her vote.

        Attendance at the Pacific Premier special meeting will not, in and of itself, constitute revocation of a proxy.

        Each proxy returned to Pacific Premier (and not revoked) by a holder of Pacific Premier common stock will be voted in accordance with the instructions indicated thereon. If no instructions are indicated on a signed proxy that is returned, such proxy will be voted "FOR" approval of the proposal to issue shares of Pacific Premier common stock to the HEOP shareholders pursuant to the merger agreement and "FOR" the proposal to adjourn the Pacific Premier special meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the Pacific Premier special meeting to approve the issuance of shares of Pacific Premier common stock in connection with the merger.

Quorum

        A quorum, consisting of the holders of a majority of the shares entitled to vote at the Pacific Premier special meeting, must be present in person or by proxy before any action may be taken at the Pacific Premier special meeting. Once a share of Pacific Premier common stock is represented at the Pacific Premier special meeting, it will be counted for the purpose of determining a quorum not only at the Pacific Premier special meeting but also at any adjournment or postponement of the Pacific Premier special meeting. In the event that a quorum is not present at the Pacific Premier special meeting, it is expected that the Pacific Premier special meeting will be adjourned or postponed.

        Abstentions and broker non-votes will not be counted for purposes of determining the number of votes cast on a proposal but will be treated as present for quorum purposes. "Broker non-votes" are shares held by banks, brokers or nominees as to which voting instructions have not been received from the beneficial owners or the persons entitled to vote those shares and the bank, broker or nominee does not have discretionary voting power under the applicable New York Stock Exchange rules. Under these rules, the proposals to approve the issuance of shares of Pacific Premier common stock to the shareholders of HEOP pursuant to the merger agreement and to adjourn the Pacific Premier special meeting, if necessary, are not items on which brokerage firms may vote in their discretion on behalf of their clients if such clients have not furnished voting instructions.

Vote Required

        The affirmative vote of holders of the majority of the shares for which votes are cast at the Pacific Premier special meeting is needed to approve the issuance of the shares of Pacific Premier common stock to the shareholders of HEOP pursuant to the merger agreement. The affirmative vote of holders of the majority of the shares for which votes are cast at the Pacific Premier special meeting is needed to approve the proposal to adjourn the Pacific Premier special meeting, if necessary.

        Abstentions and broker non-votes will not be counted as votes cast and, therefore, will not affect either proposal. Further, the failure to vote, either by proxy or in person, will not have an effect on either proposal.

        Unless instructions to the contrary are specified in a proxy properly voted and returned through available channels, the proxies will be voted "FOR" approval of the issuance of shares of Pacific Premier common stock to the HEOP shareholders in connection with the merger and "FOR" the

Table of Contents

proposal to adjourn the Pacific Premier special meeting, if necessary, to permit further solicitation of proxies on the proposal to approve the issuance of shares of Pacific Premier common stock to the HEOP shareholders in connection with the merger.

Solicitation of Proxies

        Pacific Premier will pay the costs of soliciting its shareholders' proxies, as well as all other costs incurred by it in connection with the solicitation of proxies from its shareholders on behalf of its board of directors. In addition to solicitation by mail, directors, officers and employees of Pacific Premier may solicit proxies from shareholders of Pacific Premier in person or by telephone, facsimile or other electronic methods without compensation other than reimbursement for their actual expenses. Pacific Premier has engaged D. F. King & Co., Inc. as its proxy solicitation firm. Such firm will be paid its customary fee of $8,500.00 and out-of-pocket expenses.

        Arrangements also will be made with custodians, nominees and fiduciaries for the forwarding of solicitation material to the beneficial owners of stock held of record by such persons, and Pacific Premier will reimburse such custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses in connection therewith.

Attending the Pacific Premier Special Meeting

        While not required, all holders of Pacific Premier common stock, including shareholders of record and shareholders who hold their shares in street name through banks, brokers or other nominees, are invited to attend the Pacific Premier special meeting. Pacific Premier shareholders of record can vote in person at the Pacific Premier special meeting. If a Pacific Premier shareholder is not a shareholder of record and would like to vote in person at the Pacific Premier special meeting, such Pacific Premier shareholder must produce a proxy executed in his or her favor by the record holder of such Pacific Premier shareholder's shares. In addition, each Pacific Premier shareholder must bring a form of personal photo identification with him or her in order to be admitted at the Pacific Premier special meeting. Pacific Premier reserves the right to refuse admittance to anyone without proper proof of share ownership or without proper photo identification. The use of cameras, sound recording equipment, communications devices or any similar equipment during the Pacific Premier special meeting is prohibited without Pacific Premier's express written consent.

Adjournments and Postponements

        Although it is not currently expected, the Pacific Premier special meeting may be adjourned or postponed, including for the purpose of soliciting additional proxies, if there are insufficient votes at the time of the Pacific Premier special meeting to approve the issuance of shares of Pacific Premier common stock to the HEOP shareholders in connection with the merger pursuant to the merger agreement or if a quorum is not present at the Pacific Premier special meeting. Other than an announcement to be made at the Pacific Premier special meeting of the time, date and place of an adjourned meeting, an adjournment generally may be made without notice. Any adjournment or postponement of the Pacific Premier special meeting for the purpose of soliciting additional proxies will allow the shareholders who have already sent in their proxies to revoke them at any time prior to their use at the Pacific Premier special meeting as adjourned or postponed.

THE HEOP SPECIAL MEETING

Time, Date and Place

        A special meeting of shareholders of HEOP will be held at                    .m., Pacific Time, on            day,             , 2017 at Heritage Oaks Bank's branch office, 545 12th Street, Paso Robles, CA 93446.

Matters to be Considered

        The purposes of the HEOP special meeting are to:

        No other business may be conducted at the HEOP special meeting. A copy of the merger agreement is included in this joint proxy statement/prospectus as Appendix A, and HEOP shareholders are encouraged to read it carefully in its entirety.

Recommendation of the HEOP Board of Directors

        The HEOP board of directors has unanimously (i) determined that each of the merger agreement and the transactions contemplated by the merger agreement are fair and reasonable, advisable and in the best interests of HEOP and its shareholders; (ii) approved the merger agreement, the merger and the transactions contemplated thereby and (iii) recommends that the HEOP shareholders approve the merger agreement. The HEOP board of directors unanimously recommends that HEOP shareholders vote "FOR" approval of the merger agreement. See "The Merger—HEOP's Reasons for the Merger" beginning on page        .

        The HEOP board of directors also unanimously recommends that HEOP shareholders vote "FOR" the proposal to adjourn the HEOP special meeting, if necessary, to permit further solicitation of proxies on the proposal to approve the merger agreement.

Shares Outstanding and Entitled to Vote; Record Date

        The close of business on                        , 2017 has been fixed by HEOP as the record date for the determination of HEOP shareholders entitled to notice of and to vote at the HEOP special meeting and any adjournment or postponement of the HEOP special meeting. At the close of business on the record date, there were            shares of HEOP common stock outstanding and entitled to vote, held by approximately            holders of record. Each share of HEOP common stock entitles the holder to one vote at the HEOP special meeting on all matters properly presented at the HEOP special meeting.

        As of the close of business on the record date for the HEOP special meeting, neither Pacific Premier nor any of its directors beneficially owned any shares of HEOP common stock.

How to Vote HEOP Shares

Shareholders of Record.

        Shareholders of record may vote by mail, telephone, via the Internet or by attending the HEOP special meeting and voting in person. If a HEOP shareholder chooses to vote by mail, he or she should simply mark the enclosed proxy card, date and sign it, and return it in the postage-paid envelope provided. Internet and telephone voting is available until             p.m., Pacific Time, on                .

Shares Held in "Street Name."

        If a HEOP shareholder's shares of HEOP common stock are held through a bank, broker or other nominee, such HEOP shareholder is considered the beneficial owner of such shares held in "street name." In such case, this joint proxy statement/prospectus has been forwarded by such HEOP shareholder's bank, broker or other nominee, who is considered, with respect to such shares, the shareholder of record. As the beneficial owner, a HEOP shareholder has the right to direct such bank, broker or other nominee how to vote the shares by following the voting instructions that they have sent, or will send, to the HEOP shareholder. Without specific instructions from the HEOP shareholder, the bank, broker or other nominee is not empowered to vote a HEOP shareholder's shares on non-routine matters such as the proposal to approve the merger agreement or the proposal of the HEOP board of directors to adjourn the HEOP special meeting, if necessary. Not voting these shares will have the effect of voting against the approval of the merger agreement, but will not have any effect on the proposal of the HEOP board of directors to adjourn the special meeting, if necessary. When the vote is tabulated for the proposals, broker non-votes, if any, will only be counted for purposes of determining whether a quorum is present. Accordingly, we advise each HEOP shareholder to promptly give instructions to his or her bank, broker or other nominee to vote "FOR" approval of the merger agreement and "FOR" the proposal to adjourn the HEOP special meeting, if necessary, by using the voting instruction card provided to such HEOP shareholder by his or her bank, broker or other nominee. Alternatively, if a HEOP shareholder is a beneficial owner and wishes to vote in person at the HEOP special meeting, the HEOP shareholder must provide a proxy executed in such HEOP shareholder's favor by the bank, broker or other nominee.

Revocation of Proxies

        A HEOP shareholder can revoke a proxy at any time before his or her shares are voted. If the HEOP shareholder is a shareholder of record, the HEOP shareholder can revoke a proxy by:

        If a HEOP shareholder has instructed a bank, broker or other nominee to vote such HEOP shareholder's shares of HEOP common stock, the HEOP shareholder must follow directions received from the bank, broker or other nominee to change his or her vote.

        Attendance at the HEOP special meeting will not, in and of itself, constitute revocation of a proxy.

        Each proxy returned to HEOP (and not revoked) by a holder of HEOP common stock will be voted in accordance with the instructions indicated thereon. If no instructions are indicated on a signed proxy that is returned, such proxy will be voted "FOR" approval of the merger agreement and "FOR" the proposal to adjourn the HEOP special meeting, if necessary, to permit further solicitation of proxies on the proposal to approve the merger agreement.

Quorum

        A quorum, consisting of the holders of a majority of the shares entitled to vote at the HEOP special meeting, must be present in person or by proxy before any action may be taken at the HEOP special meeting. Once a share of HEOP common stock is represented at the HEOP special meeting, it will be counted for the purpose of determining a quorum not only at the HEOP special meeting but also at any adjournment or postponement of the HEOP special meeting. In the event that a quorum is not present at the HEOP special meeting, it is expected that the HEOP special meeting will be adjourned or postponed.

        Abstentions and broker non-votes will not be counted for purposes of determining the number of votes cast on a proposal but will be treated as present for quorum purposes. "Broker non-votes" are shares held by banks, brokers or nominees as to which voting instructions have not been received from the beneficial owners or the persons entitled to vote those shares and the bank, broker or nominee does not have discretionary voting power under the applicable New York Stock Exchange rules. Under these rules, the proposals to approve the merger agreement and to adjourn the special meeting are not items on which brokerage firms may vote in their discretion on behalf of their clients if such clients have not furnished voting instructions.

Vote Required

        The affirmative vote of the holders of a majority of the outstanding shares of HEOP common stock is necessary to approve the merger agreement. The proposal to adjourn the special meeting, if necessary, to permit further solicitation of proxies, must be approved by the affirmative vote of a majority of the shares of HEOP common stock represented and entitled to vote at the HEOP special meeting.

        Because the proposal to approve the merger agreement is required to be approved by the holders of a majority of the outstanding shares of HEOP common stock, abstentions and broker non-votes, as well as the failure of a HEOP shareholder to vote by proxy or in person at the HEOP special meeting, will have the same effect as a vote against the proposal to approve the merger agreement.

        Because the affirmative vote of a majority of shares of HEOP common stock represented and entitled to vote at the HEOP special meeting (which shares voting affirmatively must constitute a majority of the required quorum) is needed to approve the adjournment proposal, abstentions and broker non-votes will not have any effect on the proposal of the HEOP board of directors to adjourn the special meeting, if any. However, if the number of affirmative votes cast for the adjournment proposal is a majority of the votes cast, but such votes do not constitute a majority of the quorum required to transact business at the special meeting, then abstentions and broker non-votes will have the same effect as a vote against the proposal of the HEOP board of directors to adjourn the HEOP special meeting.

Shares of HEOP Subject to Voting Agreements

        Directors and executive officers of HEOP, who collectively own and have the power to vote approximately            % of the outstanding shares of HEOP common stock as of December 12, 2016, have entered into shareholder agreements with Pacific Premier pursuant to which they have agreed, among other things, to vote all of their shares in favor of the merger agreement. See "The Merger—Shareholder Agreements" on page            .

Solicitation of Proxies

        HEOP will pay for the costs of mailing this joint proxy statement/prospectus to its shareholders, as well as all other costs incurred by it in connection with the solicitation of proxies from its shareholders

46


Table of Contents

on behalf of its board of directors. In addition to solicitation by mail, the directors, officers and employees of HEOP may solicit proxies from shareholders of HEOP in person or by telephone, facsimile or other electronic methods without compensation other than reimbursement for their actual expenses. HEOP has engaged Okapi Partners LLC as its proxy solicitation firm. Such firm will be paid its customary fee of $8,500 and out-of-pocket expenses.

        Arrangements also will be made with custodians, nominees and fiduciaries for the forwarding of solicitation material to the beneficial owners of stock held of record by such persons, and HEOP will reimburse such custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses in connection therewith.

Attending the HEOP Special Meeting

        While not required, all holders of HEOP common stock, including shareholders of record and shareholders who hold their shares in street name through banks, brokers or other nominees, are invited to attend the HEOP special meeting. Shareholders of record can vote in person at the HEOP special meeting. If a HEOP shareholder is not a shareholder of record and would like to vote in person at the HEOP special meeting, such HEOP shareholder must produce a proxy executed in his or her favor by the record holder of such HEOP shareholder's shares. In addition, each HEOP shareholder must bring a form of personal photo identification with him or her in order to be admitted at the HEOP special meeting. HEOP reserves the right to refuse admittance to anyone without proper proof of share ownership or without proper photo identification. The use of cameras, sound recording equipment, communications devices or any similar equipment during the HEOP special meeting is prohibited without HEOP's express written consent.

Adjournments and Postponements

        Although it is not currently expected, the HEOP special meeting may be adjourned or postponed, including for the purpose of soliciting additional proxies, if there are insufficient votes at the time of the HEOP special meeting to approve the proposal to approve the merger agreement or if a quorum is not present at the HEOP special meeting. Other than an announcement to be made at the HEOP special meeting of the time, date and place of an adjourned meeting, an adjournment generally may be made without notice. Any adjournment or postponement of the HEOP special meeting for the purpose of soliciting additional proxies will allow the shareholders who have already sent in their proxies to revoke them at any time prior to their use at the HEOP special meeting as adjourned or postponed.

THE MERGER

        The following information describes the material aspects of the merger agreement and the merger. This description does not purport to be complete and is qualified in its entirety by reference to the appendices to this joint proxy statement/prospectus, including the merger agreement which is attached as Appendix A and incorporated by reference into this joint proxy statement/prospectus. Stockholders of both Pacific Premier and HEOP should carefully read the appendices in their entirety.

Structure of the Merger

        Pursuant to the terms and conditions set forth in the merger agreement, HEOP will be acquired by Pacific Premier, in a transaction in which HEOP will merge with and into Pacific Premier, with Pacific Premier as the surviving corporation, which is referred to as the merger. Immediately following the consummation of the merger, Heritage Oaks Bank will be merged with and into Pacific Premier Bank, with Pacific Premier Bank as the surviving institution, which is referred to as the bank merger. Following consummation of the bank merger, Pacific Premier Bank intends to continue to operate all of the branches acquired from Heritage Oaks Bank, except for Heritage Oaks Bank's branch in Goleta, California, which will be consolidated into another Heritage Oaks Bank branch in Santa Barbara, California.

        Following the consummation of the merger, Pacific Premier's amended and restated certificate of incorporation, as amended, and amended and restated bylaws as in effect immediately prior to the merger will continue as the governing corporate documents of Pacific Premier. The directors and executive officers of Pacific Premier immediately prior to the merger will continue as the directors and executive officers of Pacific Premier after the merger, in each case, until their respective successors are duly elected or appointed and qualified. In addition, pursuant to the terms of the merger agreement, HEOP and Pacific Premier have agreed that Simone Lagomarsino, the President and Chief Executive Officer of HEOP and Heritage Oaks Bank, Michael Morris, the Chairman of the Board of HEOP and Heritage Oaks Bank, and Michael Pfau, the Vice Chairman of the Board of HEOP and Heritage Oaks Bank, will become directors of Pacific Premier and Pacific Premier Bank upon the effectiveness of the merger.

Background of the Merger

        From time to time, the board of directors of HEOP, or the Board, has considered strategic opportunities to continue building shareholder value, including acquiring other financial institutions, a merger of equals or being acquired by a larger financial institution, in an effort to better manage, among other things, the increasing regulatory burden and attendant costs and to seek better efficiencies and economies of scale.

        During early Summer 2015, HEOP was contacted unsolicited by a Southern California business bank regarding a possible business combination. The parties entered into a confidentiality agreement, HEOP's and the other financial institution's Chief Executive Officers met in-person on several occasions, including one meeting that was also attended by Michael J. Morris, Chairman of the Board, and the other financial institution's lead outside director, and there were several communications between the parties subsequent to the in-person meetings. In early Fall 2015, the parties decided to cease discussions, in part because HEOP wanted to focus its attention on addressing the joint FDIC and CA DBO consent order related to HEOP's Bank Secrecy Act and anti-money laundering compliance programs, or the Consent Order.

        In early August 2015, HEOP was contacted unsolicited by Pacific Premier, the parties entered into a confidentiality agreement, and HEOP's and Pacific Premier's Chief Executive Officers met in-person. At the in-person meeting, Pacific Premier's Chief Executive Officer presented HEOP's Chief Executive Officer with a draft letter of intent.

48


Table of Contents

        On August 22, 2015, there was a regularly scheduled meeting of the Board. At that meeting the Board had a preliminary discussion about strategic options. The Board decided that it would be in the best interests of HEOP's shareholders to engage an investment banker to assist the Board with an analysis of their strategic options, and at the same time the Board directed senior management to do some due diligence and analysis of Pacific Premier's letter of intent. The Board asked senior management to contact Sandler O'Neill regarding an investment banking engagement, and Manatt, Phelps & Phillips, LLP, or Manatt, regarding a legal engagement. The Board informed senior management that it would like to receive senior management's analysis of Pacific Premier's letter of intent, and a presentation from Sandler O'Neill regarding strategic alternatives at the Board's next scheduled meeting taking place in September 2015.

        Following the August 22, 2015 Board meeting, HEOP contacted representatives of Sandler O'Neill and with the assistance of Manatt, HEOP's Chief Executive Officer negotiated the terms of a draft engagement letter for financial advisory services with Sandler O'Neill. On September 2, 2015, the Executive Committee of the Board, or Executive Committee, met to discuss the terms of the Sandler O'Neill engagement letter. The members of the Executive Committee are as follows: Michael J. Morris, Chairman, Howard Gould, Simone Lagomarsino, Daniel O'Hare, Michael Pfau and Alexander Simas. The Executive Committee discussed the various terms of the engagement letter, provided direction to HEOP's Chief Executive Officer and authorized entry into the engagement letter with Sandler O'Neill with such changes as HEOP's Chief Executive Officer may agree to consistent with the Executive Committee's direction.

        On September 3, 2015, a letter was sent by HEOP's Chief Executive Officer to Pacific Premier's Chief Executive Officer thanking Pacific Premier for their letter of intent, and letting Pacific Premier know that HEOP's Board had instructed HEOP's Chief Executive Officer to analyze the terms and conditions of the letter of intent, and then report back to HEOP's Board at its next regularly scheduled meeting. The letter concluded by indicating that HEOP would be back in touch with Pacific Premier following that meeting.

        Following the September 2, 2015 Executive Committee meeting, and while the parties were finalizing the terms of the engagement letter, representatives of Sandler O'Neill began a process of contacting, on an anonymous basis, approximately seven financial institutions that were identified as potential partners for a strategic business combination with HEOP. These seven financial institutions were in addition to those financial institutions that HEOP already had contact with regarding a potential business combination. The purpose of the calls was to gauge interest in a potential business combination with a financial institution of HEOP's profile. On September 17, 2015, HEOP and Sandler O'Neill executed the engagement letter.

        On September 22, 2015, there was a regularly scheduled meeting of the Board. At that meeting the Board received a report from representatives of Sandler O'Neill regarding HEOP's strategic options within the context of Sandler O'Neill's contact with the seven financial institutions, as well as a report from HEOP's Chief Executive Officer on the letter of intent received from Pacific Premier in August. The Board asked various questions of the Sandler O'Neill representatives and HEOP's Chief Executive Officer, and then deliberated regarding next steps. At the conclusion of the meeting it was determined that it was not in the best interests of HEOP's shareholders to actively pursue a business combination at the time, rather it was the decision of the Board that HEOP should focus its efforts on satisfying the requirements of the Consent Order while also continuing to execute on HEOP's long-term strategic plan.

        On January 4, 2016, at the suggestion of one of the members of the Board, HEOP terminated its September 17, 2015 engagement letter with Sandler O'Neill in light of the fact that there had not been any activity under the engagement letter in more than three months.

        In late June 2016, HEOP was contacted unsolicited by a community bank providing consumer and commercial banking products and services throughout Central and Northern California, or Party A, and the parties entered into a confidentiality agreement. In late August 2016, Pacific Premier reinitiated contact with HEOP, and because the parties prior confidentiality agreement had expired, the parties entered into a new confidentiality agreement. Also during Spring 2016, Chief Executive Officer Lagomarsino and the Chief Executive Officer of a Southern California business bank, or Party B, met and started discussing a potential business combination. Chief Executive Officer Lagomarsino, Chairman of the Board Morris, Party B's Chief Executive Officer and Party B's lead outside director met to continue discussing a potential business combination on June 8, 2016. Also on June 8, 2016, Chief Executive Officer Lagomarsino and Chairman of the Board Morris met the with the Chief Executive Officer of Party A to continue to discuss a potential business combination.

        In August 2016, the Board held a strategic planning session. Representatives of Sandler O'Neill attended the strategic planning session and made a presentation to the Board. Various acquisition scenarios were discussed and likely acquirors and acquisition targets were identified. There was also discussion regarding HEOP's prospects if it remained independent. Sandler O'Neill's presentation also analyzed the financial institutions that HEOP was already having preliminary, informal discussions regarding a potential business combination. Among other things, the analysis demonstrated that Party B did not appear to have the capacity to pay much more than HEOP's current stock price in a business combination. Based on this analysis and other non-economic factors, HEOP ceased conversations with Party B shortly after the strategic planning session.

        At a September 9, 2016 meeting of the Executive Committee, HEOP's Chief Executive Officer was authorized to re-engage Manatt for assistance in connection with a potential business combination, and to enter into a new engagement letter with Sandler O'Neill for financial advisory services on substantially the same terms as the prior engagement letter between the parties. The engagement letter with Sandler O'Neill was executed on September 12, 2016.

        A meeting of the Executive Committee was held on September 22, 2016. At that meeting, the Executive Committee reviewed information regarding Party A, Pacific Premier, and a regional bank offering personal and business banking products and services, or Party C, that had been identified by a member of the Board as another potential transaction partner for HEOP. Representatives of Sandler O'Neill also briefed the Executive Committee on their discussions with each of the three financial institutions since Sandler O'Neill had been re-engaged by HEOP. Chief Executive Officer Lagomarsino noted that following preliminary conversations with Party C, it had been determined that Party C was not prepared to move forward with any potential transaction opportunities at that time, and therefore would not be participating in HEOP's process. The Executive Committee asked various questions of the representatives of Sandler O'Neill and Manatt in attendance at the meeting about the financial institutions and the presentation the Executive Committee had just heard, and then deliberated about next steps. The Executive Committee decided to request indications of interest from Party A and Pacific Premier, and representatives of Sandler O'Neill were authorized to provide bid instructions, and an October 5, 2016 deadline, for the submission of indications of interest.

        On October 4, 2016, Pacific Premier delivered its indication of interest, and on October 5, 2016 Party A delivered its indication of interest. On October 9, 2016 the Executive Committee met. Chief Executive Officer Lagomarsino and Mr. Hickey of Sandler O'Neill provided an overview of the two proposals. Mr. Hickey noted that the two parties had different business models but either could be a good strategic partner for HEOP. He went on to explain that the financial terms of both proposals were similar in that they offered 100% stock consideration; however, Party A's proposal allowed HEOP to elect to receive 10% of the consideration in cash.

        The Pacific Premier proposal provided for a fixed exchange ratio of 0.3594, which equated to consideration of $9.74 per share as of the close of trading on October 6, 2016. Party A's proposal

50


Table of Contents

provided for an initial exchange ratio calculated using 125% of HEOP's thirty trading-day, pre-announcement average common stock price as the numerator and 100% of Party A's thirty trading-day, pre-announcement average common stock price as the denominator, which equated to consideration of $10.47 per share as of the close of trading on October 6, 2016. Party A proposed to fix the amount of consideration to be paid by using a variable exchange ratio between signing and closing, subject to a plus/minus 10% "collar." As a result, Party A's exchange ratio would adjust from its initially determined amount to keep the amount of consideration constant, if and as fluctuations in Party A's common stock price resulted in changes to its thirty trading-day average stock price; provided, that the exchange ratio would become fixed, if and at the point that Party A's thirty trading-day average stock price increased or decreased 10% or more comparing the thirty trading-day averages prior to signing and prior to closing.

        Mr. Hickey also summarized, compared and contrasted various other terms of the two proposals such as the treatment of outstanding equity awards and the conditions to closing, among other things, including noting that while Pacific Premier included an exclusivity requirement in their proposal, Party A had not. Mr. Hickey then walked the Executive Committee through Sandler O'Neill's presentation, and various members of the Executive Committee asked questions of Mr. Hickey during the course of his presentation. Following the conclusion of Mr. Hickey's presentation, Mr. Hamburger of Manatt presented a review of fiduciary duties to the Executive Committee.

        After hearing the presentations from the representatives of Sandler O'Neill and Manatt, the Executive Committee deliberated and determined that it was not ready to enter into exclusive negotiations with either party. The Executive Committee decided that it would like each of the parties to conduct further due diligence and provide updated proposals by October 24, 2016 based on substantially complete due diligence. At the same time, the Executive Committee instructed Chief Executive Officer Lagomarsino to perform in-depth reverse due diligence on each of the parties, using the reverse due diligence request list provided in advance to the Executive Committee with the other materials for the meeting. Chief Executive Officer Lagomarsino indicated that she would need to involve the following members of HEOP's senior management team to conduct the reverse due diligence on both parties: William Schack, Chief Credit Officer, Joseph Stronks, Chief Information Officer, Jason Castle, Chief Financial Officer, and Greg Gehlmann, Chief Bank Counsel.

        All of the members of the Executive Committee and the representatives of Sandler O'Neill and Manatt who were present at the October 9, 2016 meeting agreed that keeping the process competitive by encouraging both parties to remain engaged was in the best interests of HEOP and its shareholders, and that allowing both parties to perform further due diligence while HEOP's senior management conducted reverse due diligence would permit the Board to make a more well-informed decision when the updated proposals were submitted on October 24, 2016. Finally, Mr. Hamburger noted that in addition to considering the economics of the two proposals, it was important for the Board to understand and weigh other factors, including the regulatory profiles of each bank, the ability of each bank to complete the transaction and to do so in a timely manner, and the likelihood of a successful integration of HEOP resulting in synergistic benefits for HEOP and its shareholders.

        A Board meeting was convened on October 16, 2016. The purpose of the meeting was to update the Board regarding what had transpired with respect to the transaction process since the last meeting of the Board, so the Board would be fully informed and have time to contemplate the matters it would be asked to pass upon at the October 26, 2016 regularly scheduled meeting. Chief Executive Officer Lagomarsino explained to the Board that final proposals had been requested from Pacific Premier and Party A by October 24, 2016 and the Executive Committee planned to make a recommendation to the Board regarding the proposals at the October 26, 2016 meeting. Mr. Hamburger provided the Board with a presentation regarding their fiduciary duties when considering a potential business combination. Then Mr. Hickey addressed the Board and reviewed Sandler O'Neill's presentation.

51


Table of Contents

        First, Mr. Hickey discussed HEOP on a standalone basis, so the Board could consider the transaction proposals as compared to the scenario where HEOP continued to operate independently. Next, Mr. Hickey provided an overview and evaluation of the terms of the proposals received on October 4, 2016 and October 5, 2016. Mr. Hickey emphasized that, in addition to considering the terms of each proposal, it was important for the Board to gain an understanding of the fundamentals underlying the stock of each of Pacific Premier and Party A that HEOP's shareholders would receive as consideration in the transaction. He noted the reverse due diligence being performed by HEOP's senior management would form the basis for such an understanding. Mr. Hickey suggested that the Board should also consider the impact the transaction would likely have on each of Pacific Premier and Party A in an effort to evaluate the value of their respective franchises on a go-forward basis. Lastly, Mr. Hickey noted that both Pacific Premier's and Party A's stock had greater liquidity than HEOP's common stock, which could make it easier for shareholders of HEOP to liquidate their holdings in a reasonable period of time following the consummation of either transaction, if they desired to do so. Throughout Sandler O'Neill's presentation, members of the Board asked various questions and engaged in dialogue with Mr. Hickey and Chief Executive Officer Lagomarsino.

        Following the conclusion of Sandler O'Neill's presentation, the Board was informed that both Pacific Premier and Party A were being provided access to additional due diligence materials that each party had requested, and that HEOP expected to receive final, fully-diligenced proposals on October 24, 2016. Chief Executive Officer Lagomarsino noted that HEOP senior management and the representatives of Sandler O'Neill and Manatt had taken great care to make sure that both parties had access to the same due diligence information throughout the process. The Board was informed that both Pacific Premier and Party A had opened data rooms, HEOP's senior management had commenced reverse due diligence, and in-person due diligence sessions were being scheduled.

        On October 25, 2016 the Executive Committee held a meeting. Chief Executive Officer Lagomarsino opened the meeting detailing the transaction related activity since the prior meeting of the Executive Committee on October 9, 2016. She explained that senior management, with the assistance of representatives of Manatt and Sandler O'Neill, had conducted an intensive two week period of reverse due diligence, and at the time of the Executive Committee meeting reverse due diligence was substantially complete. Supplementing the document-based reverse due diligence, all five members of HEOP's senior management had met with nine members of Pacific Premier's management team on October 20, 2016, with representatives of Sandler O'Neill and Pacific Premier's financial advisor, Davidson, present at the in-person meeting. On October 22, 2016, Chief Executive Officer Lagomarsino, Chief Bank Counsel Gehlmann and Chief Credit Officer Schack participated in an in-person diligence session with Party A's Chief Executive Officer, CFO and CCO. During the in-person sessions both diligence and reverse due diligence were performed.

        Chief Executive Officer Lagomarsino informed the Executive Committee that Pacific Premier had submitted an updated proposal on October 24, 2016 and earlier in the day on October 25, 2016 Party A also submitted an updated proposal. Chief Executive Officer Lagomarsino asked Mr. Hickey to provide an overview of the revised proposals. Mr. Hickey explained that Party A's proposal was nearly identical to its prior proposal. Party A's exchange ratio formulation remained the same, but due to the decrease in Party A's common stock price since the date of its last proposal, the transaction consideration per share had decreased from $10.47 to $10.06 based on the closing price of Party A's stock on October 25, 2016. Mr. Hickey reported to the Executive Committee the amount of time Party A had spent in the virtual data room and noted that Party A had stated it was substantially complete with its due diligence review of HEOP.

        Mr. Hickey moved on to discuss Pacific Premier's updated proposal, indicating that Pacific Premier had increased its exchange ratio to a fixed exchange ratio of 0.3728. Mr. Hickey noted that although Pacific Premier had increased its exchange ratio, because Pacific Premier's stock price had declined since the date of its last proposal, the transaction consideration per share had gone down from $9.74 to

52


Table of Contents

$9.23 based on the closing price of Pacific Premier's stock on October 25, 2016. Mr. Hickey reported that Pacific Premier had spent approximately seven times more hours in the virtual data room than Party A and noted that Pacific Premier had stated it was also substantially complete with its due diligence review of HEOP. Mr. Hickey explained that Pacific Premier had expressed some concern regarding one particular due diligence finding, and in its updated proposal had conditioned delivery of a draft definitive agreement on resolution of that concern. Mr. Hickey concluded that, with the exception of the two aforementioned changes, Pacific Premier's updated proposal was substantially similar to its prior proposal.

        Next, Chief Executive Officer Lagomarsino asked Mr. Hamburger to provide the Executive Committee with an overview of HEOP senior management's reverse due diligence findings. Mr. Hamburger explained that, generally speaking, the findings with respect to both parties were satisfactory. Senior management and representatives of Sandler O'Neill and Manatt, discussed the fact that Party A was a conservative and efficiently operated bank that consistently paid a dividend in the past and had not experienced material losses even during the worst of the most recent recessionary period. However, Party A had not experienced significant growth in several years, and its loan portfolio had contracted considerably over the preceding three year period. Chief Executive Officer Lagomarsino also highlighted that senior management had identified a regulatory-related concern during reverse due diligence. She noted that during the in-person diligence session she asked about the impact of the regulatory issue on Party A's ability to obtain regulatory approval for the transaction and Party A's Chief Executive Officer indicated that he had not discussed possible implications with the regulators and that, as of such date, he had not had any conversations with his regulators about the possible transaction.

        After completing the overview of Party A, Mr. Hamburger moved on to provided an overview of Pacific Premier. He noted that Pacific Premier had grown considerably over the past several years, completing five transactions since the Fall of 2012. In contrast to Party A, Pacific Premier has not historically paid a dividend. Mr. Hamburger explained to the Executive Committee that while no issues had been uncovered during reverse due diligence, senior management noted that it was cognizant of the risk that an issue could arise in the future as a result of Pacific Premier's rapid acquisitive growth. Finally, Mr. Hamburger noted that Pacific Premier had informed HEOP that Pacific Premier had informal conversations with its regulators about a potential transaction with HEOP and that those conversations were generally positive.

        Following the conclusion of Mr. Hamburger's due diligence presentation, Chief Executive Officer Lagomarsino presented senior management's proposal for moving forward with the transaction process. Chief Executive Officer Lagomarsino would contact Party A's Chief Executive Officer and inform him that HEOP would like to move forward in the process with Party A. Chief Executive Officer Lagomarsino would ask Party A's Chief Executive Officer to deliver a draft definitive agreement, and to contact their regulators to discuss the potential transaction with HEOP generally and seek informal guidance on what, if any, impact the regulatory matter would have on obtaining regulatory approval for the transaction. At the same time, Chief Executive Officer Lagomarsino would contact Pacific Premier's Chief Executive Officer and explain that, in light of their updated proposal conditioning delivery of a definitive agreement on satisfactory resolution of the identified diligence item, HEOP was not in a position to enter into exclusive negotiations with Pacific Premier at that time. However, HEOP would maintain an open line of communication with Pacific Premier and inform Pacific Premier of any developments that would address Pacific Premier's identified diligence issue.

        Chief Executive Officer Lagomarsino went on to explain that senior management's proposal with respect to Pacific Premier was subject to the Board's determination regarding next steps with regard to the diligence issue identified by Pacific Premier. She explained that after discussing Pacific Premier's views with senior management, senior management felt it would be advisable to engage an outside consultant to look into the issue further. Chief Executive Officer Lagomarsino and a member of senior

53


Table of Contents

management had reached out to a consultant and obtained a proposal for a review. The Executive Committee then engaged in a discussion of the diligence issue, asking various questions of Chief Executive Officer Lagomarsino and Mr. Hamburger. The Executive Committee determined that it was in the best interests of HEOP and its shareholders that the matter be considered by a consultant with the added benefit of potentially providing the ability to re-engage in discussions with Pacific Premier, if negotiations with Party A were to cease, and the consultants work provided comfort to Pacific Premier. Following some additional discussion and deliberation, the Executive Committee approved senior management's proposal for moving forward as presented by Chief Executive Officer Lagomarsino.

        On October 26, 2016 there was a regularly scheduled meeting of the Board. In addition to the members of the Board and representatives of Sandler O'Neill and Manatt, the members of senior management also attended the meeting for the review of their reverse due diligence findings. Mr. Hamburger started off the meeting by conducting a discussion with the Board regarding their fiduciary duties in the context of making decisions regarding a potential transaction. Next, Chief Executive Officer Lagomarsino summarized for the Board the transaction related activity since the last Board meeting on October 16, 2016, sharing all of the details of what had been discussed at the Executive Committee meeting a day earlier. She noted that both parties had substantially completed due diligence with HEOP senior management making sure both parties had access to the same due diligence information. Chief Executive Officer Lagomarsino also noted that HEOP's senior management had conducted and substantially completed its reverse due diligence review of both parties.

        Next, Mr. Hickey walked the Board through Sandler O'Neill's presentation. He discussed the updated proposals of both Pacific Premier and Party A, focusing on the changes from their prior proposals as he had done for the Executive Committee the day prior. Members of the Board asked various questions of Mr. Hickey throughout his presentation. Following Mr. Hickey's presentation, Chief Executive Officer Lagomarsino briefed the Board on the diligence issue of concern for Pacific Premier, and she explained that senior management and the Executive Committee were recommending that the Board approve engaging a consultant to examine the issue further. Chief Executive Officer Lagomarsino emphasized that senior management and the Executive Committee believed it was prudent to have an expert look into the issue irrespective of whether a transaction process was underway and irrespective of whether it might provide Pacific Premier with the comfort it would need to move forward with definitive negotiations.

        Chief Executive Officer Lagomarsino then transitioned to an overview of the reverse due diligence process and asked Mr. Hamburger to walk the Board through the findings of that diligence process. Mr. Hamburger, together with the member of HEOP senior management responsible for the particular area of reverse due diligence, provided a summary of the diligence results, doing so in greater detail than the summary provided to the Executive Committee the day prior. During the course of the reverse due diligence review, to the extent applicable, each member of senior management compared and contrasted their findings with respect to Pacific Premier and Party A to HEOP's comparable data points, and the members of the Board asked various questions of senior management and Mr. Hamburger. In between the discussions of the reverse due diligence findings with respect to Pacific Premier and Party A, the Board revisited the diligence issue of concern for Pacific Premier, and engaged in an in-depth discussion of the issue with Chief Executive Officer Lagomarsino and one of the members of senior management.

        Following the conclusion of the discussion of the reverse due diligence findings with respect to Party A, Chief Executive Officer Lagomarsino presented senior management's recommendations with respect to the two proposals and next steps to the Board, noting that the day prior the Executive Committee had approved senior management's recommendations, and the Executive Committee was recommending that the Board approve senior management's recommendations. Chief Executive Officer Lagomarsino also asked the Board to separately take action to authorize the engagement of the

54


Table of Contents

consultant to look into the due diligence issue identified by Pacific Premier. A discussion followed with the members of the Board participating and asking questions, which were answered by Chief Executive Officer Lagomarsino, Mr. Hickey and Mr. Hamburger. The Board deliberated further and then approved senior management's recommendation with respect to the two proposals, and the Board also approved engaging a consultant to perform an investigation of the diligence issue.

        On November 13, 2016 the Executive Committee held a meeting. Chief Executive Officer Lagomarsino started off the meeting providing an update on transaction activity since the meeting of the Board on October 26, 2016. She noted that while she was in contact with Party A's Chief Executive Officer, she had not received any update on Party A's communications with its regulators, despite having emphasized to Party A's Chief Executive Officer the importance to HEOP of gaining an understanding of the implications of Party A's regulatory issue. Mr. Hamburger commented that he had also been in communication with Party A's outside legal counsel, and that he had not received any information regarding Party A's communications with its regulators either. Members of the Executive Committee asked questions of Chief Executive Officer Lagomarsino and Mr. Hamburger regarding the regulatory issue and the circumstances surrounding Party A's approach to its communications with its regulators. The Executive Committee expressed growing concern that more than two weeks had passed since Chief Executive Officer Lagomarsino communicated with Party A's Chief Executive Officer following the October 26, 2016 meeting and seemingly no progress had been made with respect to communications on the regulatory front. Chief Executive Officer Lagomarsino concluded her overview of Party A's activity noting that a draft definitive agreement was received from Party A on November 6, 2016. Senior management, with the assistance of representatives of Manatt and Sandler O'Neill, reviewed the draft and prepared an issues list for the Executive Committee's consideration, noting that the draft definitive agreement was a reasonable initial draft that did not pose any significant issues.

        Next, Chief Executive Officer Lagomarsino noted that a consultant had been engaged to look into the issue Pacific Premier raised concerns about during its due diligence, that the consultant had completed a substantial amount of its work, and had provided a preliminary oral report on its findings. The consultant's preliminary findings indicated that the matters it was engaged to examine did not suggest HEOP was exposed to risks any different than other financial institutions. Chief Executive Officer Lagomarsino informed the Executive Committee that following receipt of the consultant's preliminary oral report, she, Mr. Hamburger and another member of HEOP senior management had a call with members of Pacific Premier's executive management and Pacific Premier's outside legal counsel, Holland & Knight, to convey the facts identified by the consultant. Chief Executive Officer Lagomarsino noted that subsequent to the call, Pacific Premier's Chief Executive Officer indicated that if the consultant's final report was consistent with its preliminary findings, Pacific Premier would be prepared to deliver a draft definitive agreement and move forward with a transaction. Chief Executive Officer Lagomarsino indicated that she asked Pacific Premier's Chief Executive Officer if he would provide a draft definitive agreement at that point in time and not wait for the consultant's final report. Pacific Premier's Chief Executive Officer indicated he was not prepared to do so until HEOP agreed to exclusivity, but that a draft definitive agreement would be similar to the definitive agreement entered into in connection with Pacific Premier's most recently completed merger transaction. As a result, senior management, with the assistance of representatives of Manatt and Sandler O'Neill, reviewed Pacific Premier's most recently executed definitive agreement and prepared an issues list for the Executive Committee's consideration, noting that the agreement was in a reasonable form that did not present any significant issues.

        Following the conclusion of Chief Executive Officer Lagomarsino's overview, Mr. Hamburger provided the Executive Committee with an overview of the two merger agreement issues lists. As Mr. Hamburger walked through Party A's draft definitive agreement issues list, he noted the issues where Chief Executive Officer Lagomarsino had already had preliminary conversations with Party A's Chief Executive Officer regarding HEOP's concerns. Members of the Executive Committee asked

55


Table of Contents

questions of Chief Executive Officer Lagomarsino and Mr. Hamburger. Mr. Hamburger concluded by noting that, in his opinion, Party A's draft definitive agreement was somewhat more acquiree friendly than Pacific Premier's precedent agreement.

        Next, Mr. Hickey led a discussion regarding the movements in the stock prices of HEOP's, Pacific Premier's and Party A's common stock since the start of the transaction discussions, including noting the movements in stock prices and activity as a result of the presidential election, and the implications of the changes on the transaction consideration under both Pacific Premier's fixed exchange ratio and Party A's "collared" exchange ratio formulation. Mr. Egli, of Sandler O'Neill, then reviewed in detail Sandler O'Neill's presentation on the implied per share transaction prices over time, and throughout Mr. Egli's presentation members of the Executive Committee asked questions of Mr. Egli and Mr. Hickey. At the conclusion of Mr. Hickey's and Mr. Egli's presentation, Chief Executive Officer Lagomarsino informed the Executive Committee that she had been in communication with Pacific Premier's Chief Executive Officer who had indicated that Pacific Premier would be providing HEOP with an updated proposal in the near term. The Executive Committee discussed next steps with both parties and the timing of the same before adjourning the meeting.

        Another Executive Committee meeting was held on November 18, 2016. Chief Executive Officer Lagomarsino indicated that since the last Executive Committee meeting on November 13, 2016, and in anticipation of receiving an updated proposal from Pacific Premier, HEOP provided its Pacific Premier precedent agreement issues list to Pacific Premier. Chief Executive Officer Lagomarsino also informed the Executive Committee that HEOP had received the final report from the consultant regarding the due diligence issue identified by Pacific Premier, which report was consistent with the consultant's preliminary findings, and that she had shared the report with Pacific Premier and Party A. Switching to Party A, Chief Executive Officer Lagomarsino stated that she had a few communications with Party A's Chief Executive Officer, but no progress had been made by Party A with its regulators. Party A's Chief Executive Officer had informed Chief Executive Officer Lagomarsino that a call had been scheduled with its regulators for November 21, 2016. Mr. Hamburger noted that his communications with Party A's outside legal counsel were consistent with Chief Executive Officer Lagomarsino's communications with Party A's Chief Executive Officer.

        Next, Mr. Hickey reviewed Sandler O'Neill's presentation materials for the meeting comparing the terms of Pacific Premier's most recent proposal received on November 15, 2016 to Party A's most recent proposal from October 25, 2016. Mr. Hickey noted that Pacific Premier had lowered its exchange ratio from 0.3728 to 0.3386, which equated to consideration of $10.92 per share as of the close of trading on November 16, 2016. Chief Executive Officer Lagomarsino noted that in Pacific Premier's most recent proposal it addressed most of the points raised in HEOP's Pacific Premier precedent agreement issues list, and that Pacific Premier did so in ways that were favorable to HEOP. Mr. Hickey continued to walk the Executive Committee through Sandler O'Neill's presentation and the members of the Executive Committee asked various questions. Following discussion and deliberation among the members of the Executive Committee, the Executive Committee authorized senior management to re-engage in negotiations with Pacific Premier to seek to obtain an increase in the proposed exchange ratio.

        On November 20, 2016 a meeting of the Board was convened. First, Chief Executive Officer Lagomarsino updated the Board on the transaction activity since the October 26, 2016 Board meeting. She noted that to her knowledge, Party A had not made any progress with its regulators regarding an understanding of the implications of its regulatory issue on regulatory approval for a transaction with HEOP. Chief Executive Officer Lagomarsino explained that Party A had provided HEOP with a draft definitive agreement, which was reviewed by senior management, and an issues list was prepared with the assistance of representatives of Manatt and Sandler O'Neill that was included with the materials for the November 20, 2016 Board meeting. Chief Executive Officer Lagomarsino indicated that Party A

56


Table of Contents

had a call scheduled with its regulators the following day, and Party A's Chief Executive Officer indicated he would update Chief Executive Officer Lagomarsino on November 22, 2016.

        Next, Chief Executive Officer Lagomarsino summarized the key milestones in the transaction process with Pacific Premier, including noting that subsequent to the last Board meeting on October 26, 2016 Pacific Premier had submitted updated proposals on November 15, 2016 and November 18, 2016. Chief Executive Officer Lagomarsino explained to the Board that Pacific Premier was unwilling to provide a draft definitive agreement before HEOP committed to exclusive negotiations, so senior management reviewed the definitive agreement for the transaction most recently completed by Pacific Premier, which Pacific Premier's Chief Executive Officer had indicated to Chief Executive Officer Lagomarsino would be similar to the draft definitive agreement HEOP should expect to receive. With the assistance of representatives of Manatt and Sandler O'Neill an issues list had been prepared, which was included with the materials for the November 20, 2016 Board meeting. Chief Executive Officer Lagomarsino noted that the issues list had been provided to Pacific Premier so that Pacific Premier could address HEOP's issues in its November 15, 2016 proposal. She indicated that Pacific Premier lowered the exchange ratio from 0.3728 to 0.3386 in the November 15, 2016 proposal but otherwise incorporated several changes noted in HEOP's issues list in a manner favorable to HEOP. Chief Executive Officer Lagomarsino informed the Board that the proposed exchange ratio was increased from 0.3386 to 0.3471 in Pacific Premier's November 18, 2016 proposal, which equated to consideration of $11.09 per share as of the close of trading on November 18, 2016, after she and representatives of Sandler O'Neill, at the direction of the Executive Committee, pushed Pacific Premier to raise the exchange ratio back to prior levels. Chief Executive Officer Lagomarsino concluded, noting that Pacific Premier's Chief Executive Officer was clear that the November 18, 2016 proposal reflected Pacific Premier's best and final offer, and that the offer was only valid until 5 pm PT on November 21, 2016.

        Mr. Hamburger provided the Board with additional detail on the matters from HEOP's issues list that Pacific Premier accepted, as well as those that were not accepted. Mr. Hickey then updated the Board on Sandler O'Neill's communications with both Davidson and Party A since the last Board meeting on October 26, 2016. The members of the Board asked questions of Mr. Hamburger, Chief Executive Officer Lagomarsino, Mr. Hickey and Mr. Egli. Next, Mr. Hickey presented Sandler O'Neill's presentation, which focused on the changes to Pacific Premier's proposal since the October 26, 2016 Board meeting. Mr. Hickey noted that Party A had not updated its proposal since the October 26, 2016 Board meeting. Members of the Board asked various questions of the representatives of Sandler O'Neill, which were addressed by Mr. Hickey and Mr. Egli. Chief Executive Officer Lagomarsino also informed the Board that the consultant's work relating to the due diligence issue identified by Pacific Premier had been completed, finding that HEOP was not exposed to any greater risk than other financial institutions, and that the report had been shared with Pacific Premier and Party A.

        A lengthy discussion among the Board members ensued. The Board concluded, and the representatives of Sandler O'Neill and Manatt concurred, that Party A had not acted with urgency at any point in the transaction process, including with respect to gaining comfort from its regulators regarding its regulatory issue. The Board expressed serious doubt that Party A and HEOP would get to a signed definitive agreement, and even if the parties did, the Board felt there was too much uncertainty surrounding obtaining the necessary regulatory approval for a transaction involving Party A. The Board then discussed various approaches with respect to Pacific Premier, including accepting Pacific Premier's current offer and different methods of countering Pacific Premier's current offer. The Board also discussed whether the events of the previous weeks, namely the presidential election, changed the Board's view on remaining independent. Following further deliberation, the Board determined that a sale transaction and the resultant combined banking franchise would deliver significantly greater value to HEOP's shareholders than continuing to operate on an independent basis. The Board also decided to authorize Chief Executive Officer Lagomarsino to try one final time to get Pacific Premier to increase its exchange ratio.

        At a special meeting of the Board the following day, November 21, 2016, the members of the Board, with representatives from Sandler O'Neill and Manatt present, further discussed the updated letter of intent from Pacific Premier. Chairman Morris noted that earlier in the day Chief Executive Officer Lagomarsino had updated the Board by email regarding what had transpired since the Board's meeting the day prior, namely that Chief Executive Officer Lagomarsino had made a final attempt to negotiate an increase of the proposed exchange ratio, but that Pacific Premier had refused to make any further changes. After that, Mr. Hamburger was asked to summarize the required Board and shareholder approval thresholds for the letter of intent and definitive agreement, respectively. Following Mr. Hamburger's summary, the Board voted to approve entering into the letter of intent with Pacific Premier containing the terms set forth in the November 18, 2016 proposal, and moving forward with negotiating a definitive agreement with Pacific Premier.

        On November 22, 2016, Chief Executive Officer Lagomarsino had a telephone conversation with Party A's Chief Executive Officer. CEO Lagomarsino informed Party A's Chief Executive Officer that HEOP was ceasing discussions with Party A due to HEOP's concerns regarding Party A's regulatory issue and its potential impact on regulatory approval for a business combination between Party A and HEOP.

        Following the Thanksgiving holiday, on November 30, 2016, Pacific Premier's legal counsel, Holland & Knight, delivered an initial draft of the definitive agreement to HEOP. Over the course of the following eight days, HEOP and its advisors, on the one hand, and Pacific Premier and its advisors, on the other, negotiated the definitive agreement, with negotiations concluding on or about December 8, 2016. During the course of negotiations, the terms remained substantially consistent with the terms outlined in the executed letter of intent. The parties also negotiated a form of shareholders agreement and HEOP prepared disclosure schedules as a companion to the definitive agreement.

        On December 7, 2016, the Board held a special meeting to review the terms of the definitive agreement and Sandler O'Neill's presentation relating to the financial aspects of the transaction. Mr. Hamburger provided the Board with a summary of all of the terms and conditions of the definitive agreement on an Article by Article basis, noting those provisions that were the subject of negotiation and summarizing the outcome of those negotiations. Throughout his presentation, members of the Board asked various questions, which Chief Executive Officer Lagomarsino and Mr. Hamburger answered. Mr. Hamburger also noted the very limited number of provisions that were still subject to further negotiation. Following the summary of the definitive agreement, Mr. Hamburger summarized the terms and conditions of the shareholders agreement. Also at the December 7, 2016 meeting, Mr. Hickey walked the Board through the process of preparing Sandler O'Neill's financial analyses and members of the Board asked questions which were answered by Mr. Hickey and Mr. Doyle of Sandler O'Neill. At the conclusion of Mr. Hickey's and Mr. Doyle's presentation, Chief Executive Officer Lagomarsino noted that the Board was planning to meet next on December 11, 2016 to take action on the definitive agreement and transactions contemplated thereby.

        On December 11, 2016, the Board held a special board meeting for purposes of considering the definitive agreement. At that meeting, the Board discussed and considered the terms and conditions of the transaction and the definitive agreement and shareholders agreement. Mr. Hamburger advised the Board regarding its fiduciary duties in connection with the transaction and the final changes made to the definitive agreement since the Board's last meeting on December 7, 2016. Mr. Hickey reviewed the financial aspects of the proposed transaction and rendered Sandler O'Neill's oral opinion to the Board, which was subsequently confirmed in writing on December 11, 2016, to the effect that, as of such date and subject to the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by Sandler O'Neill as set forth in such opinion, the exchange ratio in the proposed transaction was fair, from a financial point of view, to the holders of HEOP common stock. After deliberation, the Board voted unanimously to approve the definitive agreement and the

58


Table of Contents

transactions contemplated by the definitive agreement with Pacific Premier, and authorized HEOP senior management to execute the definitive agreement.

        On December 12, 2016, the board of directors of Pacific Premier held a special board meeting for purposes of considering the definitive agreement. At that meeting, the Pacific Premier board of directors discussed and considered the terms and conditions of the transaction and the definitive agreement. Holland & Knight advised the Pacific Premier board of directors respecting its duties in connection with the transaction. Davidson reviewed the financial aspects of the proposed transaction and rendered an opinion to the Pacific Premier board of directors to the effect that, as of such date and subject to the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by Davidson as set forth in such opinion, the aggregate transaction consideration to be paid by Pacific Premier to the HEOP shareholders in the transaction pursuant to the definitive agreement was fair, from a financial point of view, to the holders of Pacific Premier common stock. After deliberation, the Pacific Premier board of directors voted unanimously to approve the definitive agreement and the transactions contemplated by the definitive agreement, and authorized Pacific Premier management to execute the merger agreement.

        On December 12, 2016, HEOP and Pacific Premier executed the merger agreement and the members of the Board certain executive officers of HEOP, and Pacific Premier executed the shareholders agreement. Prior to the opening of the stock market on December 13, 2016, HEOP and Pacific Premier issued a joint press release announcing the execution of the merger agreement and both parties filed a current report on Form 8-K summarizing the terms of the pending transaction.

Pacific Premier's Reasons for the Merger and Recommendation of the Pacific Premier Board of Directors

        As part of Pacific Premier's business strategy, it evaluates opportunities to acquire bank holding companies, banks and other financial institutions. The acquisition of HEOP and Heritage Oaks Bank is consistent with this strategy. In reaching its conclusion to approve the merger and to recommend to its shareholders to approve the issuance of Pacific Premier common stock in connection with the merger, Pacific Premier's board of directors consulted with its financial advisor, D.A. Davidson & Co, or Davidson, with respect to the financial aspects of the proposed acquisition and with its legal counsel, Holland & Knight LLP, as to its legal duties and the terms of the merger agreement and related agreements. Pacific Premier entered into the merger agreement with HEOP because, among other things, Pacific Premier believes that the acquisition of HEOP and Heritage Oaks Bank will:

Opinion of Pacific Premier's Financial Advisor

        On September 27, 2016, Pacific Premier entered into an engagement agreement with Davidson to render financial advisory and investment banking services to Pacific Premier. As part of its engagement, Davidson agreed to assist Pacific Premier in analyzing, structuring, negotiating and, if appropriate, effecting a transaction between Pacific Premier and another corporation or business entity. Davidson also agreed to provide Pacific Premier's board of directors with an opinion as to the fairness, from a financial point of view, to Pacific Premier of the consideration to be paid to the holders of HEOP common stock in the proposed merger. Pacific Premier engaged Davidson because Davidson is a nationally recognized investment banking firm with substantial experience in transactions similar to the merger and is familiar with Pacific Premier and its business. As part of its investment banking business,

Table of Contents

Davidson is continually engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

        On December 12, 2016, Pacific Premier's board of directors held a meeting to evaluate the proposed merger. At this meeting, Davidson reviewed the financial aspects of the proposed merger and rendered an opinion to Pacific Premier's board that, as such date and based upon and subject to assumptions made, procedures followed, matters considered and limitations on the review undertaken, the consideration to be paid to the holders of HEOP common stock was fair, from a financial point of view, to Pacific Premier in the proposed merger.

        The full text of Davidson's written opinion, dated December 12, 2016, is attached as Appendix B to this joint proxy statement/prospectus and is incorporated herein by reference. The description of the opinion set forth herein is qualified in its entirety by reference to the full text of such opinion. Pacific Premier shareholders are urged to read the opinion in its entirety.

        Davidson's opinion speaks only as of the date of the opinion and Davidson undertakes no obligation to revise or update its opinion. The opinion is directed to Pacific Premier's board of directors and addresses only the fairness, from a financial point of view, to Pacific Premier of the consideration to be paid to the holders of HEOP common stock in the proposed merger. The opinion does not address, and Davidson expresses no view or opinion with respect to, (i) the underlying business decision of Pacific Premier to engage in or proceed with the merger, (ii) the relative merits or effect of the merger as compared to any strategic alternatives or business strategies or combinations that may be or may have been available to or contemplated by Pacific Premier or by Pacific Premier's board of directors, or (iii) any legal, regulatory, accounting, tax or similar matters relating to Pacific Premier, its shareholders or relating to or arising out of the merger. The opinion expresses no view or opinion as to any terms or other aspects of the merger. Pacific Premier and HEOP determined the consideration through the negotiation process. The opinion does not constitute a recommendation to any Pacific Premier shareholder as to how such shareholder should vote at the Pacific Premier meeting on the merger or any related matter. The opinion does not express any view as to the fairness of the amount or nature of the compensation to any of Pacific Premier's or HEOP's officers, directors or employees, or any class of such persons, relative to the merger consideration. The opinion has been reviewed and approved by Davidson's Fairness Opinion Committee in conformity with its policies and procedures established under the requirements of Rule 5150 of the Financial Industry Regulatory Authority.

        Davidson has reviewed the registration statement on Form S-4 of which this joint proxy statement/prospectus is a part and consented to the inclusion of its opinion to Pacific Premier's board of directors as Appendix B to this joint proxy statement/prospectus and to the references to Davidson and its opinion contained herein. A copy of the consent of Davidson is attached as Exhibit 99.1 to the registration statement on Form S-4.

        In connection with rendering its opinion, Davidson reviewed, analyzed and relied upon material bearing upon the merger and the financial and operating condition of Pacific Premier and HEOP and the merger, including among other things, the following:

Net Present Value Analysis for HEOP

        Davidson performed an analysis that estimated the net present value per share of HEOP common stock under various circumstances. The analysis assumed: (i) HEOP performed in accordance with average FactSet Research Systems, Inc. consensus earnings estimates for the years ending December 31, 2016, December 31, 2017 and December 31, 2018; and (ii) an estimated long-term growth rate for the years thereafter, as discussed with and confirmed by HEOP and Pacific Premier management. To approximate the terminal value of HEOP common stock at December 31, 2020, Davidson applied price to forward earnings multiples of 14.0x to 21.0x and multiples of tangible book value ranging from 160.0% to 230.0%. The income streams and terminal values were then discounted to present values using different discount rates ranging from 9.0% to 15.0% chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of HEOP common stock. In evaluating the discount rate, Davidson used industry standard methods of adding the current risk-free rate, which is based on the 10-year Treasury yield, plus the published Duff & Phelps Industry Equity Risk Premium and the published Duff & Phelps Size Premium.

        At the December 12, 2016 Pacific Premier board of directors meeting, Davidson noted that the net present value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

        As illustrated in the following tables, the analysis indicates an imputed range of values per share of HEOP common stock of $7.82 to $14.12 when applying the price to forward earnings multiples to the financial forecasts and $7.75 to $13.44 when applying the multiples of tangible book value to the financial forecasts.

Financial Impact Analysis

        Davidson performed pro forma merger analyses that combined projected income statement and balance sheet information of Pacific Premier and HEOP. Assumptions regarding the accounting treatment, acquisition adjustments and cost savings were used to calculate the financial impact that the merger would have on certain projected financial results of HEOP. In the course of this analysis, Davidson used average FactSet Research Systems, Inc. consensus earnings estimates for Pacific Premier for the years ending December 31, 2016, December 31, 2017 and December 31, 2018, and used average FactSet Research Systems, Inc. consensus earnings estimates for HEOP for the years ending December 31, 2016, December 31, 2017 and December 31, 2018. This analysis indicated that the merger is expected to be accretive to Pacific Premier's estimated earnings per share in 2017, after excluding non-recurring transaction-related expenses. The analysis also indicated that the merger is expected to be immediately accretive to tangible book value per share for Pacific Premier and that Pacific Premier would maintain capital ratios in excess of those required for Pacific Premier to be considered well-capitalized under existing regulations. For all of the above analyses, the actual results achieved by Pacific Premier and HEOP prior to and following the merger will vary from the projected results, and the variations may be material.

        Davidson prepared its analyses for purposes of providing its opinion to Pacific Premier's board of directors as to the fairness, from a financial point of view, to Pacific Premier of the consideration to be paid to the holders of HEOP common stock in the proposed merger and to assist Pacific Premier's board of directors in analyzing the proposed merger. The analyses do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than those suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties and their respective advisors, none of Pacific Premier, HEOP or Davidson or any other person assumes responsibility if future results are materially different from those forecasted.

        Davidson's opinion was one of many factors considered by the Pacific Premier's board of directors in its evaluation of the merger and should not be viewed as determinative of the views of the board of directors of Pacific Premier or management with respect to the merger or the merger consideration.

        Davidson and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions. Davidson acted as financial advisor to Pacific Premier in connection with, and participated in certain of the negotiations leading to the merger. Davidson is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Davidson and its affiliates may provide such services to Pacific Premier, HEOP and their respective affiliates, may actively trade the debt and equity securities (or related derivative securities) of Pacific Premier and HEOP for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities. Pacific Premier selected Davidson as its financial advisor because it is a recognized investment banking firm that has substantial experience in transactions similar to the merger. Pursuant to a letter agreement dated September 27, 2016, Pacific Premier engaged Davidson as its financial advisor in connection with the contemplated transaction. Pursuant to the terms of the engagement letter, Pacific Premier agreed to pay Davidson a cash fee of $250,000 concurrently with the rendering of its opinion. Pacific Premier will pay to Davidson at the time of closing of the merger a contingent cash fee equal to 0.85% of the aggregate merger consideration. Pacific Premier has also agreed to reimburse Davidson for all reasonable out-of-pocket expenses, including fees of counsel, and to indemnify Davidson and certain related persons against

78

specified liabilities, including liabilities under the federal securities laws, relating to or arising out of its engagement.

        Davidson's Relationship.    Davidson has, in the past, provided certain investment banking services to Pacific Premier and its affiliates, has had a material relationship with Pacific Premier and its affiliates and has received compensation and reimbursement of out-of-pocket expenses for such services. During the two (2) years preceding the date of the opinion, Davidson received compensation for acting as Pacific Premier's financial advisor on the acquisition of Security California Bancorp in 2015 as well as the acquisition of Independence Bank in 2014. Additionally, Davidson may provide investment banking services to the combined company in the future and may receive future compensation.

Opinion of HEOP's Financial Advisor

        HEOP retained Sandler O'Neill to act as financial advisor to HEOP's board of directors in connection with HEOP's consideration of a possible business combination. Sandler O'Neill is a nationally recognized investment banking firm whose principal business specialty is financial institutions. In the ordinary course of its investment banking business, Sandler O'Neill is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

        Sandler O'Neill acted as financial advisor in connection with the proposed transaction and participated in certain of the negotiations leading to the execution of the merger agreement. At the December 11, 2016 meeting of HEOP's board of directors meeting at which HEOP's board considered and discussed the terms of the merger agreement and the merger, Sandler O'Neill delivered to HEOP's board of directors its oral opinion, which was subsequently confirmed in writing on December 11, 2016, to the effect that, as of such date, the exchange ratio provided for in the merger agreement was fair to the holders of HEOP common stock from a financial point of view. The full text of Sandler O'Neill's opinion is attached as Appendix C to this joint proxy statement/prospectus. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Sandler O'Neill in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the full text of the opinion. Holders of HEOP common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

        Sandler O'Neill's opinion speaks only as of the date of the opinion. The opinion was directed to HEOP's board of directors in connection with its consideration of the merger agreement and the merger and does not constitute a recommendation to any shareholder of HEOP as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the merger agreement and the merger. Sandler O'Neill's opinion was directed only to the fairness, from a financial point of view, of the exchange ratio to the holders of HEOP common stock and does not address the underlying business decision of HEOP to engage in the merger, the form or structure of the merger or any other transactions contemplated in the merger agreement, the relative merits of the merger as compared to any other alternative transactions or business strategies that might exist for HEOP or the effect of any other transaction in which HEOP might engage. Sandler O'Neill did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the merger by any officer, director or employee of HEOP or Pacific Premier, or any class of such persons, if any, relative to the compensation to be received in the merger by any other shareholder, including the exchange ratio to be received by the holders of HEOP common stock. Sandler O'Neill's opinion was approved by Sandler O'Neill's fairness opinion committee.

        In connection with its opinion, Sandler O'Neill reviewed and considered, among other things:

79


Table of Contents

        Sandler O'Neill also discussed with certain members of the senior management of HEOP the business, financial condition, results of operations and prospects of HEOP and held similar discussions with certain members of the senior management of Pacific Premier regarding the business, financial condition, results of operations and prospects of Pacific Premier.

        In performing its review, Sandler O'Neill relied upon the accuracy and completeness of all of the financial and other information that was available to and reviewed by it from public sources, that was provided to Sandler O'Neill by HEOP or Pacific Premier or their respective representatives or that was otherwise reviewed by Sandler O'Neill, and Sandler O'Neill assumed such accuracy and completeness for purposes of rendering this opinion without any independent verification or investigation. Sandler O'Neill relied on the assurances of the respective managements of HEOP and Pacific Premier that they were not aware of any facts or circumstances that would have made any of such information inaccurate or misleading. Sandler O'Neill had not been asked to and did not undertake an independent verification of any of such information and did not assume any responsibility or liability for the accuracy or completeness thereof. Sandler O'Neill did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of HEOP or Pacific Premier or any of their respective subsidiaries, nor was Sandler O'Neill

80


Table of Contents

furnished with any such evaluations or appraisals. Sandler O'Neill rendered no opinion or evaluation on the collectability of any assets or the future performance of any loans of HEOP or Pacific Premier. Sandler O'Neill did not make an independent evaluation of the adequacy of the allowance for loan losses of HEOP or Pacific Premier, or of the combined entity after the merger, and it did not review any individual credit files relating to HEOP or Pacific Premier. Sandler O'Neill assumed, with HEOP's consent, that the respective allowances for loan losses for both HEOP and Pacific Premier were adequate to cover such losses and would be adequate on a pro forma basis for the combined entity.

        In preparing its analyses, Sandler O'Neill used publicly available consensus mean analyst estimates for HEOP for the years ending December 31, 2016, December 31, 2017 and December 31, 2018, as well as estimated long-term annual earnings and asset growth rates for HEOP for the years thereafter, as provided by the senior management of HEOP. In addition, Sandler O'Neill used publicly available consensus mean analyst estimates for Pacific Premier for the years ending December 31, 2016, December 31, 2017 and December 31, 2018, as well as estimated long-term annual earnings and asset growth rates for the years thereafter, as provided by the senior management of Pacific Premier. Sandler O'Neill also received and used in its pro forma analyses certain assumptions relating to purchase accounting adjustments, cost savings and transaction expenses, as provided by the senior management of Pacific Premier. With respect to the foregoing information, the respective senior managements of HEOP and Pacific Premier confirmed to Sandler O'Neill that such information reflected (or, in the case of the publicly available consensus mean analyst earnings per share estimates referred to above, were consistent with) the best currently available estimates and judgments of those respective senior managements as to the future financial performance of HEOP and Pacific Premier, respectively, and the other matters covered thereby, and Sandler O'Neill assumed that the future financial performance reflected in such information would be achieved. Sandler O'Neill expressed no opinion as to such information, or the assumptions on which such information was based. Sandler O'Neill also assumed that there had been no material change in the respective assets, financial condition, results of operations, business or prospects of HEOP or Pacific Premier since the date of the most recent financial statements made available to Sandler O'Neill. Sandler O'Neill assumed in all respects material to their analysis that HEOP and Pacific Premier would remain as going concerns for all periods relevant to their analysis.

        Sandler O'Neill also assumed, with HEOP's consent, that (i) each of the parties to the merger agreement would comply in all material respects with all material terms and conditions of the merger agreement and all related agreements, that all of the representations and warranties contained in such agreements were true and correct in all material respects, that each of the parties to such agreements would perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements were not and would not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on HEOP, Pacific Premier or the merger or any related transaction, (iii) the merger and any related transactions would be consummated in accordance with the terms of the merger agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements, and (iv) the merger would qualify as a tax-free reorganization for federal income tax purposes. Finally, with HEOP's consent, Sandler O'Neill relied upon the advice that HEOP received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the merger and the other transactions contemplated by the merger agreement. Sandler O'Neill expressed no opinion as to any such matters.

        Sandler O'Neill's opinion was necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to it as of, the date thereof. Events occurring after the date thereof could materially affect Sandler O'Neill's opinion. Sandler O'Neill has

81


Table of Contents

not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events occurring after the date thereof. Sandler O'Neill expressed no opinion as to the trading values of HEOP common stock or Pacific Premier common stock at any time or what the value of Pacific Premier common stock would be once it is actually received by the holders of HEOP common stock.

        In rendering its opinion, Sandler O'Neill performed a variety of financial analyses. The summary below is not a complete description of the analyses underlying Sandler O'Neill's opinion or the presentation made by Sandler O'Neill to HEOP's board of directors, but is a summary of all material analyses performed and presented by Sandler O'Neill. The summary includes information presented in tabular format. In order to fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Sandler O'Neill believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses to be considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Sandler O'Neill's comparative analyses described below is identical to HEOP or Pacific Premier and no transaction is identical to the merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or merger transaction values, as the case may be, of HEOP and Pacific Premier and the companies to which they are being compared. In arriving at its opinion, Sandler O'Neill did not attribute any particular weight to any analysis or factor that it considered. Rather, Sandler O'Neill made qualitative judgments as to the significance and relevance of each analysis and factor. Sandler O'Neill did not form an opinion as to whether any individual analysis or factor (positive or negative) considered in isolation supported or failed to support its opinion, rather, Sandler O'Neill made its determination as to the fairness of the exchange ratio on the basis of its experience and professional judgment after considering the results of all its analyses taken as a whole.

        In performing its analyses, Sandler O'Neill also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which are beyond the control of HEOP, Pacific Premier and Sandler O'Neill. The analyses performed by Sandler O'Neill are not necessarily indicative of actual values or future results, both of which may be significantly more or less favorable than suggested by such analyses. Sandler O'Neill prepared its analyses solely for purposes of rendering its opinion and provided such analyses to HEOP's board of directors at its December 11, 2016 meeting. Estimates on the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Sandler O'Neill's analyses do not necessarily reflect the value of HEOP common stock or the prices at which HEOP common stock or Pacific Premier common stock may be sold at any time. The analyses of Sandler O'Neill and its opinion were among a number of factors taken into consideration by HEOP's board of directors in making its determination to approve the merger agreement and should not be viewed as determinative of the exchange ratio or the decision of HEOP's board of directors or management with respect to the fairness of the merger. The type and amount of consideration payable in the merger were determined through negotiation between HEOP and Pacific Premier.

        Summary of Proposed Exchange Ratio and Implied Transaction Metrics.    Sandler O'Neill reviewed the financial terms of the proposed merger. Using the closing price of Pacific Premier common stock on December 9, 2016 of $34.65 for valuing Pacific Premier common stock issuable in the merger,

82


Table of Contents

Pacific Premier common stock that may be issued pursuant to the exercise of HEOP options and restricted stock awards that were outstanding on December 6, 2016 and would convert into Pacific Premier equivalent awards in the merger, and cash payments payable by Pacific Premier to settle certain HEOP restricted stock units, Sandler O'Neill calculated an aggregate implied transaction value of approximately $417.8 million, or an implied transaction price per share of HEOP common stock of $12.03. Based upon historical financial information for HEOP as or for the last twelve months (LTM) ended September 30, 2016 and mean analyst estimates for 2016, 2017, and 2018 as provided by the respective senior managements of HEOP and Pacific Premier, Sandler O'Neill calculated the following implied transaction metrics:

Transaction Price / Tangible Book Value Per Share of HEOP

    221 %

Transaction Price / Last Twelve Months Earnings Per Share of HEOP

    26.1 x

Transaction Price / 2016E Earnings Per Share of HEOP

    7  

(1)
Tangible book premium to core deposits calculated as deal value less tangible common equity, as a percentage of core deposits (defined as total deposits less time deposits with balances over $100,000).

        Contribution Analysis.    Sandler O'Neill reviewed the relative contribution of various balance sheet and income statement items to be made by HEOP and Pacific Premier to the combined entity based on financial information for both companies as of or for the period ended September 30, 2016 and mean analyst estimates for 2016, 2017, and 2018 as provided by the respective senior managements of HEOP and Pacific Premier. The results of this analysis are set forth in the following table:

        Stock Trading History.    Sandler O'Neill reviewed the historical stock price performance of HEOP common stock and Pacific Premier common stock for the one and three-year periods ended December 9, 2016. Sandler O'Neill then compared the relationship between the stock price performance of HEOP's common stock and Pacific Premier's common stock, respectively, to movements in their respective peer groups (as described below) as well as certain stock indices.

        Net Present Value Analyses.    Sandler O'Neill performed an analysis that estimated the net present value per share of HEOP common stock assuming HEOP performed in accordance with mean publicly available analyst estimates for the years ending December 31, 2016 and December 31, 2017 and December 31, 2018 and estimated long-term annual earnings growth rate, dividend and other assumptions as provided by the senior management of HEOP. To approximate the terminal value of a share of HEOP common stock at December 31, 2020, Sandler O'Neill applied price to 2020 earnings per share multiples ranging from 15.0x to 20.0x and price to December 31, 2020 tangible book value per share multiples ranging from 120% to 220%. The terminal values were then discounted to present values using different discount rates ranging from 7.0% to 13.0% which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of HEOP common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of HEOP common stock of $8.57 to $13.74 when applying multiples of earnings per share and $6.25 to $12.99 when applying multiples of tangible book value per share.

        Sandler O'Neill also considered and discussed with the HEOP board of directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to net income. To illustrate this impact, Sandler O'Neill performed a similar analysis assuming HEOP's net income varied from 25% above projections to 25% below estimates. This analysis resulted in the following range of per share values for HEOP common stock, applying the price to 2020 earnings per share multiples range of 15.0x to 20.0x referred to above and a discount rate of 8.17%.

        Pro Forma Merger Analysis.    Sandler O'Neill analyzed certain potential pro forma effects of the merger, assuming the merger closes at the end of the first calendar quarter of 2017. In performing this analysis, Sandler O'Neill utilized the following information: (i) mean publicly available analyst estimates for HEOP and Pacific Premier for the years ending December 31, 2016, December 31, 2017 and December 31, 2018 and estimated long-term annual earnings and assets growth rates, dividend and other assumptions as provided by the respective senior managements of HEOP and Pacific Premier; and (ii) certain assumptions relating to purchase accounting adjustments, cost savings and transaction expenses, as provided by the senior management of Pacific Premier. The analysis indicated that the merger could be accretive to Pacific Premier's earnings per share (excluding one-time transaction costs and expenses) in the years ended December 31, 2017, December 31, 2018, December 31, 2019, and December 31, 2020 and accretive to Pacific Premier's estimated tangible book value per share at close and accretive to Pacific Premier's estimated tangible book value per share at December 31, 2017, December 31, 2018, December 31, 2019, and December 31, 2020.

        In connection with this analysis, Sandler O'Neill considered and discussed with the HEOP board of directors how the analysis would be affected by changes in the underlying assumptions, including the impact of final purchase accounting adjustments determined at the closing of the transaction, and noted that the actual results achieved by the combined company may vary from projected results and the variations may be material.

        Sandler O'Neill's Relationship.    Sandler O'Neill has acted as HEOP's financial advisor in connection with the merger and will receive a fee for its services estimated to be approximately $4.19 million based on the market value of Pacific Premier's common stock at the time the merger was announced. The fee is equal to 1.00% of the aggregate purchase price, will vary based on the market value of Pacific Premier common stock at the time of closing and a substantial portion of Sandler O'Neill's fee is contingent upon the closing of the merger. Sandler O'Neill also received a $300,000 fee upon rendering its fairness opinion to the HEOP board of directors, which opinion fee will be credited in full towards the portion of the transaction fee which will become payable to Sandler O'Neill on the day of closing of the merger. HEOP has also agreed to indemnify Sandler O'Neill against certain claims and liabilities arising out of its engagement and to reimburse Sandler O'Neill for certain of its out-of-pocket expenses incurred in connection with its engagement.

        In the two (2) years preceding the date of its opinion, Sandler O'Neill did not provide any other investment banking services to HEOP for which Sandler O'Neill received compensation nor did Sandler O'Neill provide any investment banking services to Pacific Premier in the two (2) years preceding the date of its opinion. In the ordinary course of its business as a broker-dealer, Sandler O'Neill may purchase securities from and sell securities to HEOP and its affiliates. Sandler O'Neill may also actively trade the equity and debt securities of HEOP, Pacific Premier and their respective affiliates for its own account and for the accounts of its customers.

The Merger Consideration

General.

        At the effective time of the merger, each share of HEOP common stock outstanding immediately before the effective time of the merger, will, by virtue of the merger and without any action on the part of a HEOP shareholder, be converted into the right to receive whole shares of common stock of Pacific Premier. Cash will be paid in lieu of fractional shares of Pacific Premier common stock. Since the federal income tax consequences will be dependent on the form of consideration received, you are urged to read carefully the information set forth below under "—Material Federal Income Tax Consequences" beginning on page            .

Merger Consideration.

        Upon consummation of the merger, each share of HEOP common stock issued and outstanding immediately prior to the effective time of the merger will be canceled and converted into the right to receive 0.3471 shares of Pacific Premier common stock, which is referred to as the exchange ratio. Upon completion of the merger, and based on 34,355,624 shares of HEOP common stock outstanding as of the date of this joint proxy statement/prospectus, HEOP shareholders are expected to receive an aggregate of 11,924,837 shares of Pacific Premier common stock, which does not include shares of Pacific Premier common stock issuable to holders of HEOP restricted stock that will accelerate and be entitled to the payment of the merger consideration in connection with the closing of the merger. Following the completion of the merger, and based on            shares of Pacific Premier common stock outstanding as of                 , 2017, the former HEOP shareholders will own approximately            % of the outstanding shares of Pacific Premier common stock and the current shareholders of Pacific Premier will own the remaining approximately            % of the outstanding shares of Pacific Premier common stock.

Aggregate Merger Consideration.

        The total consideration to be paid by Pacific Premier to the HEOP shareholders in connection with the merger is referred to in this joint proxy statement/prospectus as the aggregate merger consideration. The term aggregate merger consideration does not include the consideration, if any, payable to holders of (i) options to purchase shares of HEOP common stock, (ii) restricted shares of HEOP common stock, or (iii) restricted stock units of HEOP. In this joint proxy statement/prospectus, we refer to stock options to purchase shares of HEOP's common stock as HEOP options, restricted shares of HEOP common stock as HEOP restricted stock, and restricted stock units as HEOP restricted stock units.

        Upon completion of the merger and based on a $26.46 closing price of Pacific Premier's common stock on September 30, 2016, approximately $315.53 million of aggregate merger consideration will be payable to the HEOP shareholders. The foregoing sentence does not include the payment of cash to the holders of HEOP restricted stock units whose restricted stock units will accelerate in connection with the closing of the merger and assumes (i) there are 34,355,624 shares of HEOP common stock outstanding at the closing, (ii) the HEOP shareholders will receive an aggregate of 11,924,837 shares of Pacific Premier common stock after applying the exchange ratio of 0.3471, and (iii) there is no acceleration of vesting of shares of HEOP restricted stock in connection with the closing of the merger that would result in such shares of HEOP restricted stock being converted into the right to receive the merger consideration in the merger.

Fractional Shares.

        No fractional shares of Pacific Premier common stock will be issued, and in lieu thereof, each holder of HEOP common stock who would otherwise be entitled to a fractional share interest will receive an amount in cash, without interest, determined by multiplying such fractional interest by the Pacific Premier average share price, rounded to the nearest whole cent. No such holder shall be entitled to dividends, voting rights or any other rights in respect of any fractional share of Pacific Premier common stock.

HEOP Options, HEOP Restricted Stock and HEOP Restricted Stock Units

HEOP Options.

        Each outstanding and unexercised option to acquire shares of HEOP common stock will be assumed by Pacific Premier and converted automatically into an option to purchase shares of Pacific Premier common stock, which is referred to as a converted HEOP option. The number of shares of

92


Table of Contents

Pacific Premier common stock subject to each such converted HEOP option shall be equal to the number of shares of HEOP common stock subject to the original HEOP option immediately prior to the closing of the merger multiplied by the exchange ratio, provided that any fractional shares of Pacific Premier common stock resulting from such multiplication shall be rounded down to the nearest share. The per share exercise price under each such converted HEOP option will be adjusted by dividing the per share exercise price under the original HEOP option by the exchange ratio, provided that such exercise price will be rounded up to the nearest cent.

HEOP Restricted Stock Units.

        The board of directors of HEOP intends to accelerate the vesting of HEOP restricted stock units and HEOP restricted stock held by directors, officers and employees of HEOP or its subsidiaries that are not expected to continue with Pacific Premier or its subsidiaries following the closing of the merger.

        Each cash-settled HEOP restricted stock unit which is vested and outstanding as of the closing of the merger will be entitled to receive a single lump sum cash payment equal to the sum of (i) the product of (A) and (B) where (A) equals the product of the number of HEOP restricted stock units and the exchange ratio and (B) equals the Pacific Premier average share price, plus (ii) any HEOP dividends previously accrued, provided that any fractional HEOP restricted stock units remaining will be converted into an amount determined by multiplying the fractional share interest by the Pacific Premier average share price, rounded to the nearest whole cent.

        Each unvested cash-settled HEOP restricted stock unit which is outstanding as of the closing of the merger will be assumed by Pacific Premier and will be converted into a right to receive cash payments based upon the values of shares of Pacific Premier common stock. The number of shares of Pacific Premier common stock referenced in each cash-settled HEOP restricted stock unit will be equal to the number of shares of HEOP common stock subject to such cash-settled HEOP restricted stock unit immediately prior to the effective time of the merger multiplied by the exchange ratio, including any fractional shares of Pacific Premier common stock. Any dividends accrued with respect to cash-settled HEOP restricted stock units will continue to be accrued and deferred until such time as the award vests and is paid.

HEOP Restricted Stock.

        Each unvested award of HEOP restricted stock that is outstanding as of the closing of the merger will be assumed by Pacific Premier and converted into shares of Pacific Premier common stock. The number of shares of Pacific Premier common stock subject to each assumed award of HEOP restricted stock will be equal to the number of shares of HEOP common stock subject to such award of HEOP restricted stock immediately prior to the effective time of the merger multiplied by the exchange ratio, provided that any fractional shares of Pacific Premier common stock will be converted into cash in lieu of fractional shares of Pacific Premier common stock. Based on 188,519 shares of unvested HEOP restricted stock, 65,435 shares of Pacific Premier common stock would be issuable to holders of unvested awards of HEOP restricted stock as of that date.

HEOP Performance-Based Restricted Stock Units.

        Pacific Premier will not assume outstanding performance-based HEOP restricted stock units issued for the performance period extending from January 1, 2016 through December 31, 2018. The performance-based HEOP restricted stock units will become vested immediately prior to the effective time of the merger, and each of the holders thereof will be entitled to receive a single lump sum cash payment equal to the product of (A), (B) and (C), where (A) equals 100% of the target number of shares of HEOP common stock subject to the performance-based HEOP restricted stock units, (B) equals the exchange ratio, and (C) equals the Pacific Premier average share price.

Procedures for Exchanging HEOP Common Stock Certificates

        Promptly following the closing of the merger, American Stock Transfer & Trust Company, the exchange agent, will mail to each holder of record of HEOP common stock a notice and form of transmittal letter advising such holder of the effectiveness of the merger and the procedure for surrendering to the exchange agent certificates representing shares or book-entry shares of HEOP common stock in exchange for the merger consideration allocated to them. Upon surrender of a stock certificate or book-entry shares of HEOP common stock for exchange and cancellation to the exchange agent, together with a duly executed transmittal letter, the holder of such certificate or book-entry shares will be entitled to receive the merger consideration allocated to him or her and the certificate or book-entry shares for HEOP common stock so surrendered will be canceled. No interest will be paid or accrued on any cash paid in lieu of fractional shares of Pacific Premier common stock.

        HEOP shareholders who surrender their stock certificates or book-entry shares and complete the transmittal materials, or who have taken other steps to surrender the evidence of their stock interest in HEOP in accordance with the instructions accompanying the transmittal letter, will, upon the exchange agent's acceptance of such stock certificates or book-entry shares and transmittal materials or stock interest, be entitled to evidence of issuance in book entry form, or upon written request of such holder, a certificate or certificates representing, the number of whole shares of Pacific Premier common stock in to which the aggregate number of shares of HEOP common stock surrendered have been converted pursuant to the merger agreement.

        Any HEOP shareholder who receives shares of Pacific Premier common stock in the merger will receive dividends on Pacific Premier common stock or other distributions declared after the completion of the merger only if he or she has surrendered his or her HEOP stock certificates. Only then will the HEOP shareholder be entitled to receive all previously withheld dividends and distributions, without interest. Pacific Premier has never declared or paid dividends on its common stock and does not anticipate declaring or paying any cash dividends in the foreseeable future.

        After completion of the merger, no transfers of HEOP common stock issued and outstanding immediately prior to the completion of the merger will be allowed. HEOP stock certificates that are presented for transfer after the completion of the merger will be canceled and exchanged for the appropriate merger consideration.

        Pacific Premier will only issue a Pacific Premier stock certificate in a name other than the name in which a surrendered HEOP stock certificate is registered if a HEOP shareholder presents the exchange agent with all documents required to show and effect the unrecorded transfer of ownership of the shares of HEOP common stock formerly represented by such HEOP stock certificate, and that the HEOP shareholder has paid any applicable stock transfer taxes.

        If a HEOP shareholder has lost his or her HEOP stock certificate, or the HEOP stock certificate has been lost, stolen or destroyed, the HEOP shareholder may be required to deliver an affidavit and a lost certificate bond as a condition to receiving any merger consideration to which he or she may be entitled.

Conditions to the Merger

        Completion of the merger is subject to the satisfaction of certain conditions set forth in the merger agreement, or the waiver of such conditions by the party entitled to do so, at or before the closing date of the merger. Each of the parties' obligation to consummate the merger under the merger agreement is subject to the following conditions:

94


Table of Contents

        In addition to the foregoing conditions, the obligation of Pacific Premier to consummate the merger under the merger agreement is subject to the following conditions, which may be waived by Pacific Premier:

95


Table of Contents

        In addition to the other conditions set forth above, the obligation of HEOP to consummate the merger under the merger agreement is subject to the following conditions, which may be waived by HEOP:

        Under the terms of the merger agreement, a material adverse effect on either Pacific Premier or HEOP is defined to mean any effect that (i) is material and adverse to the financial condition, results of operations or business of Pacific Premier and its subsidiaries taken as a whole or HEOP and its subsidiaries taken as a whole, as the case may be, or (ii) would materially impair the ability of Pacific Premier and its subsidiaries taken as a whole or HEOP and its subsidiaries taken as a whole, as the case may be, to perform their respective obligations under the merger agreement or otherwise materially impede the consummation of the merger. However, under the terms of the merger agreement, none of the following would be deemed to constitute a material adverse effect under subclause (i) above:

96


Table of Contents

provided that the effect of the changes described in the first, second, third and fourth bullet points above will not be excluded as a material adverse effect to the extent of a materially disproportionate impact, if any, that they have on Pacific Premier and its subsidiaries as a whole on the one hand, or HEOP and its subsidiaries on the other hand, as measured relative to similarly situated companies in the banking industry.

Bank Regulatory Approvals

        The merger cannot be completed unless the parties receive prior approvals from the CA DBO and the Federal Reserve.

California Department of Business Oversight—Division of Financial Institutions; Board of Governors of the Federal Reserve System.

        In order to consummate the merger, the prior approval of the CA DBO will be required under the California Financial Code, or CFC, and the prior approval of the Federal Reserve will be required under the Bank Merger Act as well as the Bank Holding Company Act of 1956, as amended, or BHC Act. In reviewing the merger, the CA DBO and the Federal Reserve will take competitive considerations into account, as well as capital adequacy, quality of management and earnings prospects. The regulators will also take into account the record of performance of Pacific Premier Bank in meeting the credit needs of the communities that it serves and Pacific Premier Bank's regulatory rating under the Community Reinvestment Act, or CRA. Pacific Premier Bank and Heritage Oaks Bank both received a "satisfactory" performance rating in their most recent CRA evaluations. In considering the merger, the CFC also requires the CA DBO to consider whether the proposed transaction will be fair, just, and equitable to the bank being acquired and the surviving depository institution.

        Any transaction approved by the Federal Reserve under the Bank Merger Act and BHC Act may not be completed until thirty (30) days after the Federal Reserve's approval, during which time the U.S. Department of Justice may challenge such transaction on antitrust grounds. With the approval of the Federal Reserve and the U.S. Department of Justice, the waiting period may be reduced to fifteen (15) days. While Pacific Premier and HEOP do not know of any reason that the U. S. Department of Justice would challenge regulatory approval by the Federal Reserve and believe that the likelihood of such action is remote, there can be no assurance that the U.S. Department of Justice will not initiate such a proceeding, or if such a proceeding is initiated, the result of any such challenge.

Other Regulatory Approvals.

        Neither Pacific Premier nor HEOP is aware of any other regulatory approvals that would be required for completion of the merger except as described above. Should any other approvals be

97


Table of Contents

required, it is presently contemplated that such approvals would be sought. There can be no assurance, however, that any other approvals, if required, will be obtained.

Status of Applications.

        Pacific Premier will file all required applications with the CA DBO and the Federal Reserve. There can be no assurance that all requisite approvals will be obtained, that such approvals will be received on a timely basis or that such approvals will not impose conditions, restrictions or requirements (other than conditions or requirements related to remedial actions) which, individually or in the aggregate, would so materially reduce the economic benefits of the transactions contemplated by the merger agreement to Pacific Premier that had such condition, restriction or requirement been known or could reasonably have been known, Pacific Premier, in its reasonable, good faith judgment, would not have entered into the merger agreement. If any such condition or requirement is imposed, Pacific Premier, in its reasonable discretion, may elect not to consummate the merger. See "—Conditions to the Merger" beginning on page        . The approval of any application or notice merely implies satisfaction of regulatory criteria for approval, and does not include review of the merger from the standpoint of the adequacy of the merger consideration to be received by, or fairness to, HEOP shareholders. Regulatory approval does not constitute an endorsement or recommendation of the proposed merger.

Business Pending the Merger

        The merger agreement contains certain covenants of the parties regarding the conduct of their respective businesses pending consummation of the merger. These covenants, which are contained in Article IV of the merger agreement included as Appendix A to this joint proxy statement/prospectus, are briefly described below.

        Pending consummation of the merger, HEOP may not, and will cause each of its subsidiaries not to, among other things, take the following actions without the prior written consent of Pacific Premier:

98

Table of Contents

        The merger agreement also provides that pending consummation of the merger, Pacific Premier may not, and will cause each of its subsidiaries not to, take the following actions without the prior written consent of HEOP:

HEOP Board of Directors' Covenant to Recommend the Merger Agreement

        Pursuant to the merger agreement, the HEOP board of directors is required to recommend that HEOP shareholders approve the merger agreement at all times prior to and during the HEOP special meeting at which the merger agreement is to be considered by them. The HEOP board of directors may not withdraw, modify or qualify in any manner adverse to Pacific Premier such recommendation or take any other action or make any other public statement in connection with the HEOP special meeting inconsistent with such recommendation, except as described below. Regardless of whether the HEOP board of directors changes its recommendation, the merger agreement must be submitted to the HEOP shareholders at the HEOP special meeting for the purpose of approving the merger agreement and any other matters required to be approved by HEOP's shareholders for consummation of the transaction. HEOP may not submit to the vote of its shareholders any acquisition proposal other than the merger.

        The HEOP board of directors is permitted to change its recommendation if HEOP has complied with the merger agreement and the HEOP board of directors, based on the advice of its outside counsel and financial advisor, has determined in good faith that failure to do so would result in a violation of the board of directors' fiduciary duties under applicable law. If the HEOP board of directors intends to change its recommendation following an acquisition proposal, as described in

101


Table of Contents

"—No Solicitation" below, it must have first concluded in good faith, after giving effect to all of the adjustments to the terms and conditions of the merger agreement that may be offered by Pacific Premier, that another acquisition proposal constitutes a superior proposal, as defined in "—No Solicitation" below. HEOP also must notify Pacific Premier at least five (5) business days in advance of its intention to change its recommendation in response to the superior proposal, including the identity of the party making the acquisition proposal, and furnish to Pacific Premier all of the material terms and conditions of such superior proposal. Prior to changing its recommendation, HEOP must, and must cause its financial and legal advisors to, during the period following its delivery of the required notice, negotiate in good faith with Pacific Premier for a period of up to five (5) business days to the extent Pacific Premier desires to negotiate to make adjustments in the terms and conditions of the merger agreement so that the other acquisition proposal ceases to constitute a superior proposal.

        Pursuant to the merger agreement, the Pacific Premier board of directors is required to recommend that Pacific Premier shareholders approve the issuance of Pacific Premier common stock to the shareholders of HEOP in connection with the merger and any other matters required to be approved by Pacific Premier shareholders for consummation of the merger at all times prior to and during the Pacific Premier special meeting.

No Solicitation

        The merger agreement provides that HEOP will, and will direct and use its reasonable best efforts to cause its affiliates, directors, officers, employees, agents and representatives to, immediately cease any discussions or negotiations with any other parties that have been ongoing with respect to the possibility or consideration of any acquisition proposal and will use its reasonable best efforts to enforce any confidentiality or similar agreement relating to any acquisition proposal. For purposes of the merger agreement, "acquisition proposal" is defined to mean any inquiry, proposal or offer, filing of any regulatory application or notice, whether in draft or final form, or disclosure of an intention to do any of the foregoing from any person relating to any (i) direct or indirect acquisition or purchase of a business that constitutes 10% or more of the total revenues, net income, assets, or deposits of HEOP and its subsidiaries taken as a whole; (ii) direct or indirect acquisition or purchase of any class of equity securities representing 10% or more of the voting power of HEOP or Heritage Oaks Bank; (iii) tender offer or exchange offer that if consummated would result in any person beneficially owning 10% or more of any class of equity securities of HEOP or Heritage Oaks Bank; or (iv) merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving HEOP or Heritage Oaks Bank, other than the transactions contemplated by the merger agreement.

        From the date of the merger agreement through the effective time of the merger, HEOP will not, and will use reasonable efforts to cause its directors, officers or employees or any other representative retained by it not to, directly or indirectly through another person (i) solicit, initiate, or encourage, including by way of furnishing information or assistance, or take any other action designed to facilitate or that is likely to result in, any inquiries or the making of any proposal or offer that constitutes, or is reasonably likely to lead to, any acquisition proposal, (ii) provide any confidential information or data to any person relating to any acquisition proposal, (iii) participate in any discussions or negotiations regarding any acquisition proposal, (iv) waive, terminate, modify, or fail to enforce any provision of any contractual "standstill" or similar obligations of any person other than Pacific Premier or its affiliates, (v) approve or recommend, propose to approve or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, asset purchase agreement or share exchange agreement, option agreement or similar agreement related to any acquisition proposal or propose to take any of these actions, or (vi) make or authorize any statement, recommendation, or solicitation in support of any acquisition proposal.

102


Table of Contents

        However, prior to the date of the HEOP special meeting, if the HEOP board of directors determines in good faith, after consulting with its outside legal and financial advisors, that the failure to do so would breach, or would reasonably be expected to result in a breach of, its fiduciary duties under applicable law, HEOP may, in response to a bona fide, written acquisition proposal not solicited in violation of the merger agreement that the HEOP board of directors determines in good faith constitutes a superior proposal, subject to providing two (2) business days prior written notice of its decision to take such action to Pacific Premier and identifying the person making the proposal and all the material terms and conditions of the proposal and compliance with the merger agreement:

        For purposes of the merger agreement, "superior proposal" is defined to mean any bona fide written proposal made by a third party to acquire, directly or indirectly, including pursuant to a tender offer, exchange offer, merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction, for consideration consisting of cash and/or securities, more than 50% of the combined voting power of the shares of HEOP common stock then outstanding or all or substantially all of HEOP's consolidated assets, that the HEOP board of directors determines in good faith, after taking into account all legal, financial, regulatory, and other aspects of the proposal and the person making the proposal, including any break-up fees, expense reimbursement provisions, and conditions to consummation, and after taking into account the advice of HEOP's financial advisor, which will be a recognized investment banking firm, and outside counsel, (1) is more favorable from a financial point of view to its shareholders than the merger, (2) is reasonably likely to be consummated on the terms set forth, and (3) for which financing, to the extent required, is then committed or which, in the good faith judgment of the HEOP board of directors, is reasonably likely to be obtained by the third party.

        In addition to these obligations, HEOP will promptly, within 24 hours, advise Pacific Premier orally and in writing of its receipt of any acquisition proposal, and keep Pacific Premier informed, on a current basis, of the continuing status of the inquiry, including the material terms and conditions of the inquiry and any material changes to the inquiry, and will contemporaneously provide to Pacific Premier all materials provided to or made available to any third party that were not previously provided to Pacific Premier.

        HEOP has agreed that any violations of the restrictions set forth in the merger agreement by any representative of HEOP or its subsidiaries will be deemed a breach of the merger agreement by HEOP.

        Pacific Premier and HEOP have agreed that irreparable damage would occur in the event HEOP, its subsidiaries or any of their respective representatives violated any of the restrictions described above regarding discussions and negotiations with other parties with respect to the possibility or consideration of any acquisition proposal. As such, under the merger agreement, Pacific Premier is entitled to injunctive relief to prevent breaches of these restrictions and to enforce specifically the terms of these restrictions.

Representations and Warranties of the Parties

        Pursuant to the merger agreement, Pacific Premier and HEOP made certain customary representations and warranties relating to their respective companies, subsidiaries, businesses and matters related to the merger. For detailed information concerning these representations and

103


Table of Contents

warranties, reference is made to Article V of the merger agreement included as Appendix A to this joint proxy statement/prospectus. Such representations and warranties generally must remain accurate through the completion of the merger, unless the fact or facts that caused a breach of a representation and warranty has not had or is not reasonably likely to have a material adverse effect on the party making the representation and warranty. See "—Conditions to the Merger" beginning on page    .

        The merger agreement contains representations and warranties that Pacific Premier and HEOP made to and solely for the benefit of each other. These representations and warranties are subject to materiality standards which may differ from what may be viewed as material by investors and shareholders, and, in certain cases, were used for the purpose of allocating risk among the parties rather than establishing matters as facts. The assertions embodied in those representations and warranties also are qualified by information in confidential disclosure schedules that the parties have exchanged in connection with signing the merger agreement. Although neither Pacific Premier nor HEOP believes that the disclosure schedules contain information that the federal securities laws require to be publicly disclosed, the disclosure schedules do contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the merger agreement.

        Accordingly, neither shareholders of either HEOP or Pacific Premier should rely on the representations and warranties as characterizations of the actual state of facts, since they were only made as of the date of the merger agreement and are modified in important part by the underlying disclosure schedules. Moreover, information concerning the subject matter of the representations and warranties may have changed since the date of the merger agreement, which subsequent information may or may not be fully reflected in Pacific Premier's or HEOP's public disclosures.

Effective Time of the Merger

        Pursuant to the terms and conditions set forth in the merger agreement, HEOP will be acquired by Pacific Premier in a transaction in which HEOP will merge with and into Pacific Premier, with Pacific Premier as the surviving institution. The merger will become effective upon the acceptance of a certificate of merger to be filed with the Secretary of State of the State of Delaware in accordance with the provisions of applicable Delaware law.

Amendment of the Merger Agreement

        To the extent permitted under applicable law, the merger agreement may be amended or supplemented at any time by written agreement of the parties whether before or after the approval of the shareholders of HEOP, except that after shareholders of HEOP have approved the principal terms of the merger agreement, except as described in the next sentence, no amendment or supplement that by law requires further approval by the shareholders of HEOP may be made without first obtaining such approval. The merger agreement provides that, by approving the principal terms of the merger agreement, HEOP shareholders will be deemed to have approved any amendment to the August 30, 2017 termination date described below.

Termination of the Merger Agreement

        The merger agreement may be terminated:

104


Table of Contents

Termination Fee

        The merger agreement provides that HEOP must pay Pacific Premier a $15.0 million termination fee under the circumstances and in the manner described below:

105


Table of Contents

        Any termination fee that becomes payable pursuant to the merger agreement shall be paid by wire transfer of immediately available funds to an account designated by Pacific Premier.

        If HEOP fails to timely pay the termination fee to Pacific Premier, HEOP will be obligated to pay the costs and expenses (including reasonable legal fees and expenses) incurred by Pacific Premier to collect such payment, provided Pacific Premier prevails on the merits, together with interest.

Certain Employee Matters

        The merger agreement contains certain agreements of the parties with respect to various employee matters, which are described below.

        As soon as administratively practicable after the effective time of the merger, Pacific Premier will take all reasonable action so that employees of HEOP and its subsidiaries will be entitled to participate in the Pacific Premier and Pacific Premier Bank employee benefit plans of general applicability to the same extent as similarly-situated employees of Pacific Premier and its subsidiaries, provided that coverage shall be continued under the corresponding benefit plans of HEOP and its subsidiaries until such employees are permitted to participate in the Pacific Premier benefit plans. Pacific Premier and Pacific Premier Bank, however, shall not be under any obligation to make any grants to any former employee of HEOP and its subsidiaries under any discretionary equity compensation plan of Pacific

106


Table of Contents

Premier. For purposes of determining eligibility to participate in, the vesting of benefits and for all other purposes, other than for accrual of pension benefits under, the Pacific Premier employee benefit plans, Pacific Premier will recognize years of service with HEOP and its subsidiaries, to the same extent as such service was credited for such purpose by HEOP and its subsidiaries, except where such recognition would result in duplication of benefits. Nothing contained in the merger agreement shall limit the ability of Pacific Premier to amend or terminate any Pacific Premier or HEOP benefit plan in accordance with their terms at any time.

        At the time the employees of HEOP and its subsidiaries become eligible to participate in a medical, dental, health, life or disability plan of Pacific Premier and its subsidiaries, Pacific Premier will cause each such plan to:

        At and following the effective time of the merger, Pacific Premier shall honor and shall continue to be obligated to perform, in accordance with their terms, all benefit obligations to, and contractual rights of, current and former employees of HEOP and its subsidiaries and current and former directors of HEOP and its subsidiaries existing as of the effective date of the merger, as well as all bonus, deferred compensation, supplemental retirement plan, salary continuation, severance, termination, change in control or other existing plans and policies of HEOP and its subsidiaries that were disclosed to Pacific Premier.

        Pursuant to a severance plan previously adopted by HEOP, those employees of HEOP and its subsidiaries who are not offered employment by Pacific Premier or Pacific Premier Bank following the merger, who are not a party to an employment agreement or otherwise entitled to an existing severance package, and who sign and deliver a termination and release agreement within thirty (30) days of the closing of the merger will be entitled to receive a single lump sum payment of severance equal to two (2) weeks of salary for each year of service with HEOP, up to a maximum of six (6) months and a minimum based on the seniority of the employee.

        Pursuant to the merger agreement, HEOP is required, prior to the closing of the merger, to have made all discretionary employee contributions to the Heritage Oaks Bank retirement plan, to provide for full vesting of all non-elective contributions under such retirement plan for all participants, and to take all actions necessary to terminate such retirement plan effective no later than the business day preceding the closing date of the merger.

Assumption of HEOP Indenture Obligations

        HEOP and Pacific Premier have agreed that as of the effective time of the merger, Pacific Premier shall have assumed or caused one of its subsidiaries to assume the obligations under HEOP's three (3) existing indentures pursuant to which HEOP had junior subordinated indentures issued and outstanding with a carrying value of $10.6 million as of September 30, 2016. HEOP and Pacific Premier are required to execute and deliver any supplemental indentures and other documents reasonably requested to make such assumptions effective.

Table of Contents

Interests of Certain HEOP Officers and Directors in the Merger

        When HEOP shareholders are considering the recommendation of HEOP's board of directors with respect to approving the merger agreement, HEOP shareholders should be aware that HEOP directors and officers have interests in the merger as individuals that are in addition to, or different from, their interests as shareholders of HEOP. The HEOP board of directors was aware of these factors and considered them, among other matters, in approving the merger agreement and the merger. These interests are described below.

Stock Ownership.

        The directors and executive officers of HEOP, as a group, beneficially owned and had the power to vote as of                    , 2017, a total of 10,593,567 shares of HEOP common stock, representing approximately 30.8% of the outstanding shares of HEOP common stock as of that date. Substantially all of these shares are expected to be voted in favor of the merger agreement pursuant to the shareholder agreements entered into by each of the directors and substantially all of the executive officers of HEOP who own shares of HEOP common stock. See "—Shareholder Agreements" beginning on page    . Each of these persons will receive the same merger consideration for their shares of HEOP common stock as the other HEOP shareholders.

HEOP Options, HEOP Restricted Stock and HEOP Restricted Stock Units.

        HEOP Options.    Each outstanding and unexercised option to acquire shares of HEOP common stock will be assumed by Pacific Premier and converted automatically into an option to purchase shares of Pacific Premier common stock, which is referred to as a converted HEOP option. The number of shares of Pacific Premier common stock subject to such converted HEOP option shall be equal to the number of shares of HEOP common stock subject to such converted HEOP option immediately prior to the closing of the merger multiplied by the exchange ratio, provided that any fractional shares of Pacific Premier common stock resulting from such multiplication shall be rounded down to the nearest share. The per share exercise price under each such converted HEOP option will be adjusted by dividing the per share exercise price under each such converted HEOP option by the exchange ratio, provided that such exercise price will be rounded up to the nearest cent.

        HEOP Restricted Stock Units.    The board of directors of HEOP intends to accelerate the vesting of HEOP restricted stock units and HEOP restricted stock held by directors, officers and employees of HEOP or its subsidiaries that are not expected to continue with Pacific Premier or its subsidiaries following the closing of the merger.

        Each cash-settled HEOP restricted stock unit which is vested and outstanding as of the closing of the merger, will be entitled to receive a single lump sum cash payment, equal to the sum of (i) the product of (A) and (B) where (A) equals the product of the number of HEOP restricted stock units and the exchange ratio and (B) equals the Pacific Premier average share price, plus (ii) any HEOP dividends previously accrued, provided that any fractional HEOP restricted stock units remaining will be converted into an amount determined by multiplying the fractional share interest by the Pacific Premier average share price, rounded to the nearest whole cent.

        Each unvested cash-settled HEOP restricted stock unit which is outstanding as of the closing of the merger, will be assumed by Pacific Premier and will be converted into a right to receive cash payments based upon the values of shares of Pacific Premier common stock. The number of shares of Pacific Premier common stock referenced in each cash-settled HEOP restricted stock unit will be equal to the number of shares of HEOP common stock subject to such cash-settled HEOP restricted stock unit immediately prior to the effective time of the merger multiplied by the exchange ratio, including any fractional shares of Pacific Premier common stock. Any dividends accrued with respect to

108


Table of Contents

cash-settled HEOP restricted stock units will continue to be accrued and deferred until such time as the award vests and is paid.

        HEOP Restricted Stock.    Each unvested award of HEOP restricted stock that is outstanding as of the closing of the merger will be assumed by Pacific Premier and converted into shares of Pacific Premier common stock. The number of shares of Pacific Premier common stock subject to each award of HEOP restricted stock will be equal to the number of shares of HEOP common stock subject to such award of HEOP restricted stock immediately prior to the effective time of the merger multiplied by the exchange ratio, provided that any fractional shares of Pacific Premier common stock will be converted into cash in lieu of fractional shares of Pacific Premier common stock. Based on 65,722 shares of unvested HEOP restricted stock at September 30, 2016, 189,584 shares of Pacific Premier common stock would be issuable to holders of unvested awards of HEOP restricted stock as of that date.

        HEOP Performance-Based Restricted Stock Units.    Pacific Premier will not assume outstanding performance-based HEOP restricted stock units issued for the performance period extending from January 1, 2016 through December 31, 2018. The performance-based HEOP restricted stock units will become vested immediately prior to the effective time of the merger, and each of the holders thereof will be entitled to receive a single lump sum cash payment equal to the product of (A), (B) and (C), where (A) equals 100% of the target number of shares of HEOP common stock subject to the performance-based HEOP restricted stock units, (B) equals the exchange ratio, and (C) equals the Pacific Premier average share price.

Appointment of HEOP Directors to the Boards of Directors of Pacific Premier and Pacific Premier Bank Boards.

        Pursuant to the terms of the merger agreement, Pacific Premier agreed to take all necessary action following completion of the merger to appoint Simone Lagomarsino, the president and chief executive officer of HEOP and Heritage Oaks Bank, Michael Morris, the chairman of the board of HEOP and Heritage Oaks Bank, and Michael Pfau, the vice chairman of the board of HEOP and Heritage Oaks Bank, a to serve on the boards of directors of Pacific Premier and Pacific Premier Bank until the first annual meeting of shareholders of Pacific Premier following the merger and until their successors are elected and qualified. As directors of Pacific Premier and Pacific Premier Bank, Ms. Lagomarsino and Messrs. Morris and Pfau will be entitled to receive the same director compensation that the current directors of Pacific Premier and Pacific Premier Bank receive.

Community Advisory Board

        Pursuant to the terms of the merger agreement, effective as of the closing of the merger, Pacific Premier Bank will establish a Community Advisory Board for the Central Coast Region, which shall be comprised of all members of the HEOP board of directors as of the closing of the merger who are willing to so serve.

Merger Related Payments Under Employment and Change in Control Severance Agreements.

        Employment Agreement.    HEOP is a party to an employment agreement with Simone Lagomarsino. The agreement provides for severance benefits in the event of certain qualifying terminations of employment, including a termination by the executive due to a change in control.

        Pursuant to the employment agreement, the merger will constitute a "change in control" entitling Ms. Lagomarsino to severance benefits if her employment is terminated (other than for cause) by HEOP or Pacific Premier, or she terminates her employment as a result of (i) a reduction of more than 15% in her annual bonus opportunity other than a general reduction in annual bonus that affects all senior executive officers in substantially the same proportions; (ii) a relocation of her principal place of

109


Table of Contents

employment which increases her commute to work by more than thirty-five (35) miles; (iii) any material breach by HEOP of any material provision of the agreement, or any material provision of any other agreement between Ms. Lagomarsino and HEOP; (iv) HEOP's failure to obtain an agreement from any successor to HEOP to assume and agree to perform the agreement in the same manner and to the same extent that HEOP would be required to perform if no succession had taken place, except where such assumption occurs by operation of law; (v) the loss of the material duties, authority and responsibility of the Chief Executive Officer of HEOP; or (vi) HEOP's failure to nominate Ms. Lagomarsino for election to the boards of HEOP and to use its best efforts to have her elected and re-elected, as applicable, within three months prior to, or within twelve months following, a "change in control".

        Upon such a termination, Ms. Lagomarsino would be entitled to (i) a lump sum payment equal to one (1) times the sum of her annual base salary and annual bonus for the year previous to the year in which the termination date occurs (or if greater, the year immediately preceding the year in which the change in control occurs); (ii) equal installment payments over a two-year period, which are in the aggregate equal to two (2) times the sum of her annual base salary and annual bonus for the year previous to the year in which the termination date occurs (or if greater, the year immediately preceding the year in which the change in control occurs); (iii) a lump sum payment equal to the product of (a) the annual bonus, if any, that she earned for the calendar year prior to the one in which the termination date occurs and (b) a fraction, the numerator of which is the number of days she was employed by HEOP during the year of termination and the denominator of which is the number of days in such year (the "Pro Rata Bonus"); and (iv) reimbursement for the difference between the monthly COBRA premiums paid by her for herself and her dependents and the monthly premiums paid by similarly situated active executives, if applicable, until the earliest of (i) the twenty-four month anniversary of her termination; (ii) the date she is no longer eligible to receive COBRA coverage; and (iii) the date on which she becomes eligible to receive substantially similar coverage from another employer.

        Executive Salary Protection Agreements.    HEOP is a party to executive salary protection agreements with each of Jason Castle, Rob Osterbauer, and William Schack. Each of these agreements provide for severance benefits in the event of certain qualifying terminations of employment, including a termination by the executive due to a change in control.

        Pursuant to each of the executive salary protection agreements, the merger will constitute a "change in control" entitling the executive to severance benefits if either the executive's employment is terminated (other than for cause) by HEOP or Pacific Premier, or the executive terminates his employment as a result of (a) a reduction by more than fifteen percent in base salary or annual bonus opportunity, other than a general reduction in base or bonus that affects all similarly situated employees in substantially the same proportions; (b) a relocation of the executive's principal place of employment by more than thirty-five miles; (c) removal from his appointed position (with respect to Mr. Schack only); (d) a material adverse change in the executive's assigned duties; or (e) the failure of a successor to assume and agree to perform the agreement, within three months prior to, or within twelve months following, a "change in control".

        Upon such a termination, each of Messrs. Castle, Osterbauer and Schack would be entitled to a lump sum equal to one and one-half times: (i) his annual salary at the rate in effect immediately prior to the triggering event; plus (ii) his cash bonus, if any, earned for the calendar year ended immediately prior to the occurrence of the triggering event. Messrs. Castle, Osterbauer and Schack also are entitled to reimbursement for the difference between the monthly COBRA premiums paid by them for themselves and their dependents and the monthly premiums paid by similarly situated active executives, if applicable, until the earliest of (i) the twelve-month anniversary of their termination; (ii) the date they are no longer eligible to receive COBRA coverage; and (iii) the date on which they become eligible to receive substantially similar coverage from another employer.

        Salary Protection Agreements.    In addition, HEOP is a party to salary protection agreements with each of Joseph Stronks, Brooks Wise, Greg Gehlmann, Josh Tucker, and two other officers. Each of these agreements provide for severance benefits in the event of certain qualifying terminations of employment, including a termination by the executive due to a change in control.

        Pursuant to each of the salary protection agreements, the merger will constitute a "change in control" entitling the executive to severance benefits if either the executive's employment is terminated (other than for cause) by HEOP or Pacific Premier, or the executive terminates his or her employment as a result of (a) a reduction by more than fifteen percent of his or her annual total cash compensation package (defined as the sum of (i) base salary, (ii) incentive bonus opportunity, and (ii) auto allowance , if applicable, other than a general reduction in annual total cash compensation that affects similarly situated employees in substantially the same proportions; (b) a relocation of the executive's principal place of employment by more than thirty-five miles; or (c) the failure of a successor to assume and agree to perform the agreement, within three months prior to, or within twelve months following, a "change in control" event as defined in the Agreement.

        Upon such a termination, Mr. Stronks would be entitled to a lump sum equal to 100% of his base salary at the rate in effect immediately prior to the triggering event. Upon such a termination, Messrs. Wise, Gehlmann, Tucker and the two other executives would be entitled to a lump sum equal to 50% of their base salary at the rate in effect immediately prior to the triggering event.

        Salary Continuation Agreement.    HEOP is party to a Salary Continuation Agreement, or SCA, with Chief Executive Officer Lagomarsino. The agreement is a non-qualified executive benefit plan that provides a post-employment monthly retirement benefit, or payments in the event of death or disability. Benefits vest over ten (10) years after the SCA issuance date and the benefit is paid monthly for fifteen (15) years after the final date of HEOP employment. The agreement provides for monthly payments or lump sum benefits in the event of early termination (without cause), disability, or death of the participant, or a change in control. The SCA contains a change in control provision which entitles Ms. Lagomarsino to full benefits under the plan if employment is terminated within twelve (12) months of a defined change in control event. The merger qualifies as a change in control under the SCA. Upon such a termination, benefits are fully vested at 100%. Currently, Ms. Lagomarsino is 50% vested under the SCA.

112


Table of Contents

Pursuant to the terms of their respective employment agreements, Messrs. Osterbauer and Wise will each be employed as an Executive Vice President, Market President, of Pacific Premier Bank.

        Each employment agreement has a term of one (1) year, unless such term is extended. On the annual anniversary of the agreements and each annual anniversary thereafter, the term of such agreement will automatically be extended for an additional one year unless either the executive or Pacific Premier Bank gives written notice not to extend the term not less than ninety (90) days prior to any such anniversary date, in which case the agreement will terminate at the conclusion of its remaining term.

        Pursuant to their respective employment agreements, Messrs. Osterbauer and Wise will receive an annual base salary of $250,000 and $210,000, respectively. In addition, they are eligible for bonuses and entitled to participate in any pension, retirement or other benefit plan or program given to employees and executives of Pacific Premier Bank, to the extent commensurate with their respective duties and responsibilities as fixed by the board of directors of Pacific Premier Bank. Messrs. Osterbauer and Wise also are entitled to a monthly automobile allowance. Each of Messrs. Osterbauer's and Wise's employment agreements includes provisions related to payments to them in certain circumstances related to termination of employment, treatment of confidential information, and restrictions against soliciting employees, vendors and customers of Pacific Premier Bank, in each case consistent with provisions included in the employment agreements of similarly-situated Pacific Premier Bank executives.

Indemnification.

        HEOP's directors, officers and employees are entitled to continuing indemnification against certain liabilities by virtue of provisions contained in the HEOP articles of incorporation, as amended, and bylaws, as amended, and the merger agreement. HEOP's articles of incorporation, as amended, are referred to as the HEOP articles of incorporation, and HEOP's bylaws, as amended, are referred to as the HEOP bylaws. Pursuant to the merger agreement, Pacific Premier agreed for a period of six (6) years from the closing of the merger, to indemnify and hold harmless each present and former director, officer and employee of HEOP or a subsidiary of HEOP, as applicable, determined as of the effective time of the merger, against any costs or expenses (including reasonable attorneys' fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or prior to the effective time of the merger, whether asserted or claimed prior to, at or after the effective time of the merger, arising in whole or in part out of or pertaining to the fact that he or she was a director, officer, employee, fiduciary or agent of HEOP or its subsidiaries or is or was serving at the request of HEOP or its subsidiaries as a director, officer, employee, fiduciary or agent of another corporation, partnership, joint venture, trust or other enterprise including, without limitation, matters related to the negotiation, execution and performance of the merger agreement or the consummation of any of the transactions contemplated by the merger agreement, to the fullest extent to which such indemnified parties would be entitled under the HEOP articles of incorporation and HEOP bylaws, or any agreement, arrangement or understanding previously disclosed by HEOP to Pacific Premier pursuant to the merger agreement, in each case as in effect on the date of the merger agreement.

        Pursuant to the merger agreement, Pacific Premier has agreed to maintain HEOP's existing directors' and officers' liability insurance policy for HEOP's directors and officers or a substitute policy which shall provide such directors and officers with coverage following the effective time of the merger for an additional six (6) years, provided that if the cost of such insurance exceeds 250% of the annual premiums paid by HEOP for its existing directors' and officers' liability insurance, which is referred to as the maximum insurance amount, Pacific Premier will obtain the most advantageous coverage as is available for the maximum insurance amount.

        Other than as set forth above, no director or officer of HEOP has any direct or indirect material interest in the merger, except insofar as ownership of HEOP common stock might be deemed such an interest.

Material Federal Income Tax Consequences

        The following is a general description of the anticipated material U.S. federal income tax consequences of the merger. This discussion is based upon the Code, Treasury regulations, judicial authorities and published positions of the Internal Revenue Service, or IRS, all as currently in effect and all of which are subject to change. Accordingly, the U.S. federal income tax consequences of the merger to the holders of HEOP common stock could differ from those described below.

        Except as specifically stated herein, this discussion is limited to U.S. holders (as defined below) that hold shares of HEOP common stock as a capital asset within the meaning of Section 1221 of the Code for U.S. federal income tax purposes. This discussion does not address the tax consequences applicable to HEOP shareholders that are not U.S. holders, nor does it address all of the tax consequences that may be relevant to particular U.S. holders that are subject to special treatment under U.S. federal income tax laws, including, without limitation, financial institutions, insurance companies, partnerships and other pass-through entities, tax-exempt organizations, regulated investment companies, real estate investment trusts, dealers in securities or currencies, U.S. persons whose functional currency is not the U.S. dollar, traders in securities that elect to use a mark-to-market method of accounting, persons that hold HEOP common stock as part of a straddle, hedge, constructive sale or conversion transaction, and U.S. holders that acquired their shares of HEOP common stock through the exercise of an employee stock option or otherwise as compensation.

        If a partnership or other entity taxed as a partnership holds HEOP common stock, the tax treatment of a partner in the partnership will depend upon the status of the partner and the activities of the partnership. Partnerships holding HEOP common stock and partners in such partnerships should consult with their tax advisors about the tax consequences of the merger to them.

        This discussion does not address the tax consequences of the merger under state, local or foreign tax laws. This discussion also does not address the tax consequences of any transaction other than the merger.

        For purposes of this section, the term "U.S. holder" means a beneficial owner of HEOP common stock that is for U.S. federal income tax purposes (i) an individual who is a citizen or resident of the United States, (ii) a corporation, or other entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any state or a political subdivision thereof, (iii) an estate that is subject to U.S. federal income tax on its income regardless of its source, or (iv) a trust, the substantial decisions of which are controlled by one or more U.S. persons and which is subject to the primary supervision of a U.S. court, or that has validly elected under applicable Treasury regulations to be treated as a U.S. person for U.S. federal income tax purposes.

Tax Consequences of the Merger.

        The parties intend for the merger to qualify as a "reorganization" under Section 368(a) of the Code for U.S. federal income tax purposes. As a condition to the completion of the merger, Holland & Knight LLP is required to deliver an opinion, dated the closing date of the merger, to the effect that the merger will be treated as a "reorganization" for U.S. federal income tax purposes within the meaning of Section 368(a) of the Code. The opinion will assume that the merger will be completed according to the terms of the merger agreement and that the parties will report the merger in a manner consistent with the opinion. The opinion will rely on the facts as stated in the merger agreement, the Registration Statement on Form S-4 filed by Pacific Premier in connection with the merger (of which this joint proxy statement/prospectus is a part) and certain other documents. In

114


Table of Contents

rendering the opinion, counsel will rely on the representations of Pacific Premier and HEOP, to be delivered at the time of closing (and counsel will assume that any representation that is qualified by belief, knowledge or materiality is true, correct and complete without such qualification). If any assumption or representation is or becomes inaccurate, the U.S. federal income tax consequences of the merger could be adversely affected. The opinion will be based on statutory, regulatory and judicial authority existing as of the date of the opinion.

        An opinion of counsel represents such counsel's best legal judgment but is not binding on the IRS or on any court. Neither Pacific Premier nor HEOP intends to request any ruling from the IRS as to the U.S. federal income tax consequences of the merger. Consequently, no assurance can be given that the IRS will not assert, or that a court will not sustain, a position contrary to any of the tax consequences set forth below or any of the tax consequences described in the opinion.

        Based on representations to be contained in representation letters of officers of Pacific Premier and HEOP, all of which must continue to be true and accurate in all material respects as of the effective time of the merger, and subject to the other matters set forth above, it is the opinion of Holland & Knight LLP that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. Based upon the foregoing, the material U.S. federal income tax consequences of the merger will be as described below.

Tax Consequences of the Merger for Pacific Premier and HEOP.

        No gain or loss will be recognized by Pacific Premier or HEOP as a result of the merger.

Tax Consequences of the Merger for U.S. Holders of HEOP Common Stock.

        Except as described below under "—Cash in Lieu of Fractional Shares of Pacific Premier Common Stock," a U.S. holder that exchanges all of its shares of HEOP common stock for shares of Pacific Premier common stock pursuant to the merger will not recognize gain or loss in connection with such exchange.

        A U.S. holder's aggregate tax basis in the Pacific Premier common stock received in the merger, including any fractional shares deemed received by the U.S. holder under the treatment discussed below under "—Cash in Lieu of Fractional Shares of Pacific Premier Common Stock," will equal such U.S. holder's aggregate tax basis in the HEOP common stock surrendered by such U.S. holder in the merger. The holding period for the shares of Pacific Premier common stock received by such U.S. holder in the merger, including any fractional shares deemed received by the U.S. holder under the treatment discussed below under "—Cash in Lieu of Fractional Shares of Pacific Premier Common Stock," will include the holding period for the shares of HEOP common stock exchanged therefor.

Cash in Lieu of Fractional Shares of Pacific Premier Common Stock.

        A U.S. holder that receives cash instead of a fractional share of Pacific Premier common stock will be treated as having received the fractional share of Pacific Premier common stock pursuant to the merger and then having exchanged the fractional share of Pacific Premier common stock for cash in a redemption by Pacific Premier. This deemed redemption will be treated as a sale or exchange and a U.S. holder will recognize gain or loss equal to the difference between (i) the amount of cash received by such U.S. holder and (ii) the portion of the basis of the shares of HEOP common stock allocable to such fractional interest. Such gain or loss will constitute capital gain or loss and will be long-term capital gain or loss if the U.S. holder's holding period for the HEOP common stock exchanged by such U.S. holder is greater than one year as of the effective time of the merger. Long-term capital gains of non-corporate U.S. holders are generally subject to reduced rates of taxation. The deductibility of capital losses is subject to limitations. Capital gains recognized by individuals, trusts and estates also may be subject to a 3.8% federal Medicare contribution tax on "net investment income" as provided in Section 1411 of the Code.

115


Table of Contents

        Notwithstanding the previous paragraph, if the receipt of the cash is deemed to be essentially equivalent to the distribution of a dividend to the U.S. holder, the cash would be treated as dividend income. While a dividend from Pacific premier would generally be treated as a "qualified dividend" and taxed at the same rates applicable to long-term capital gains, a U.S. holder would not be able to apply any portion of its basis to reduce the amount of such dividend and such basis would instead be reallocated to such U.S. holder's other Pacific Premier shares.

Information Reporting and Backup Withholding.

        Cash payments received in the merger by a U.S. holder may, under certain circumstances, be subject to information reporting and backup withholding at a current rate of 28% of the cash payable to the U.S. holder, unless the U.S. holder provides proof of an applicable exemption, furnishes its taxpayer identification number (in the case of individuals, their social security number) and otherwise complies with all applicable requirements of the backup withholding rules. Any amounts withheld from payments to a U.S. holder under the backup withholding rules are not additional tax and will be allowed as a refund or credit against the U.S. holder's U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Reporting Requirements.

        A U.S. holder that receives shares of Pacific Premier common stock as a result of the merger will be required to retain records pertaining to the merger. Each U.S. holder that is required to file a U.S. tax return and that is a "significant holder" that receives Pacific Premier common stock in the merger will be required to file a statement with the significant holder's U.S. federal income tax return setting forth such significant holder's basis (determined immediately before the exchange) in the HEOP common stock surrendered and the fair market value (determined immediately before the exchange) of the HEOP common stock that is exchanged by such significant holder. A "significant holder" is a U.S. holder that receives shares of Pacific Premier common stock in the merger and that, immediately before the merger, owned at least 5% of the outstanding stock of HEOP (by vote or value) or securities of HEOP with a tax basis of $1 million or more.

        THE FOREGOING IS NOT A SUBSTITUTE FOR AN INDIVIDUAL ANALYSIS OF THE TAX CONSEQUENCES OF THE MERGER TO HEOP SHAREHOLDERS. HEOP SHAREHOLDERS ARE URGED TO CONSULT WITH THEIR OWN TAX ADVISORS AS TO THE TAX CONSEQUENCES OF THE MERGER IN THEIR PARTICULAR CIRCUMSTANCES, INCLUDING THE APPLICABILITY AND EFFECT OF U.S. FEDERAL (INCLUDING THE ALTERNATIVE MINIMUM TAX), STATE, LOCAL OR FOREIGN AND OTHER TAX LAWS AND OF CHANGES IN THOSE LAWS.

Accounting Treatment of the Merger

        The merger will be accounted for under the acquisition method of accounting under GAAP. Under this method, HEOP's assets and liabilities as of the date of the merger will be recorded at their respective fair values and added to those of Pacific Premier. Any excess between the purchase price for HEOP and the fair value of the identifiable net assets acquired (including core deposit intangibles) will be recorded as goodwill. In accordance with FASB Accounting Standards Codification (ASC) Topic 350, "Intangibles—Goodwill and Other," the goodwill resulting from the merger will not be amortized to expense, but instead will be reviewed for impairment at least annually and to the extent goodwill is impaired, its carrying value will be written down to its implied fair value and a charge will be made to earnings. Core deposit and other intangibles with definite useful lives recorded by Pacific Premier in connection with the merger will be amortized to expense. The financial statements of Pacific Premier issued after the merger will reflect the results attributable to the acquired operations of HEOP beginning on the date of completion of the merger.

116


Table of Contents

Expenses of the Merger

        The merger agreement provides that each of HEOP and Pacific Premier will bear and pay all costs and expenses incurred by it in connection with the transactions contemplated by the merger agreement, including fees and expenses of its own financial consultants, accountants and counsel.

Listing of the Pacific Premier Common Stock

        Pacific Premier has agreed to use its reasonable best efforts to cause the shares of Pacific Premier common stock to be issued to (i) HEOP shareholders as the merger consideration, (ii) upon the exercise of HEOP options assumed by Pacific Premier, and (iii) in connection with the conversion of the unvested restricted shares of HEOP common stock into shares of Pacific Premier common stock in connection with the merger, to be approved for listing on the NASDAQ Global Select Market.

Resale of Pacific Premier Common Stock

        The shares of common stock that HEOP shareholders receive as a result of the merger will be registered under the Securities Act. HEOP shareholders may freely trade these shares of Pacific Premier common stock if such HEOP shareholder is not considered an "affiliate" of Pacific Premier, as that term is defined in the federal securities laws. Generally, "affiliates" include directors, certain executive officers and holders of 10% or more of the outstanding Pacific Premier common stock.

        Pacific Premier's affiliates may not sell their shares of Pacific Premier common stock acquired in the merger, unless those shares are registered under an effective registration statement under the Securities Act, or by complying with an applicable exemption from the registration requirements of the Securities Act. Pacific Premier may also place restrictive legends on certificates representing shares of Pacific Premier common stock issued to all persons who will be considered "affiliates" of Pacific Premier.

Shareholder Agreements

        In connection with the execution of the merger agreement, directors and substantially all executive officers of HEOP entered into a shareholder agreement with Pacific Premier pursuant to which each such director and executive officer agreed that at any meeting of the shareholders of HEOP, or in connection with any written consent of the shareholders of HEOP, the director and executive officer shall:

117


Table of Contents

        Pursuant to the shareholder agreement, each HEOP executive officer and director who entered into a shareholder agreement also agreed, while the shareholder agreement is in effect, not to, directly or indirectly, sell, transfer, pledge, encumber (except for pledges or encumbrances existing as of the date of the shareholder agreement), distribute by gift, or otherwise dispose of any of the shares whether by actual disposition, physical settlement, or effective economic disposition through hedging transactions; nor to enter into any agreement with any person that violates shareholder's representations, warranties, covenants, and obligations under the shareholder agreement; nor to take any other action that reasonably could be expected to adversely effect, in any material respect, shareholder's power, authority, and ability to comply with and perform his, her, or its covenants and obligations under the shareholder agreement. Each HEOP executive officer and director who entered into a shareholder agreement also agreed not to deposit any shares in a voting trust, grant any proxy, or enter into any voting agreement or similar agreement or arrangement with respect to any shares.

        In addition, each HEOP executive officer and director who entered into a shareholder agreement agreed that, for a period of two (2) years following the consummation of the merger, they will not:

        Except for the non-solicitation provisions referenced in the paragraph above, which will survive for a period of two (2) years following the consummation of the merger, the shareholder agreements shall remain in effect until the earlier to occur of the date, if any, of termination of the merger agreement in accordance with its terms, or the effective time of the merger.

Dissenters' Rights

        HEOP shareholders do not have the right to dissent from the merger and assert dissenters' rights.

        Under the CGCL, shareholders are generally entitled to dissent from a merger or consolidation and obtain payment of the fair value of their shares when a merger or consolidation occurs. However, the CGCL provides that appraisal rights are not available for shares that are listed on a national securities exchange where the merger consideration is stock of a publicly traded corporation. HEOP's common stock is traded on a national securities exchange and the merger consideration, comprised of Pacific Premier's common stock, is also traded on a national securities exchange. As such, HEOP's shareholders are not entitled to appraisal rights.

Dividends.

        HEOP's Board of Directors has responsibility for the oversight and approval of the declaration of dividends. Dividends HEOP declares are subject to the restrictions set forth in the CGCL. The CGCL provides that a corporation may make a distribution to its shareholders if the corporation's retained earnings equal at least the amount of the proposed distribution. The CGCL also provides that, in the event that sufficient retained earnings are not available for the proposed distribution, a corporation may nevertheless make a distribution to its shareholders if it meets two conditions, which generally stated are as follows: (i) the corporation's assets equal at least 1 and 1/4 times its liabilities, and (ii) the corporation's current assets equal at least its current liabilities or, if the average of the corporation's earnings before taxes on income and before interest expenses for the two preceding fiscal years was less than the average of the corporation's interest expenses for such fiscal years, then the corporation's current assets must equal at least 1 and 1/4 times its current liabilities. Additionally, the Federal Reserve Board has authority to limit the payment of dividends by bank holding companies, such as HEOP, in certain circumstances, requiring, among other things, a holding company to consult with the Federal Reserve Board prior to payment of a dividend if the company does not have sufficient recent earnings in excess of the proposed dividend.

        The principal source of funds from which HEOP may pay dividends is the receipt of dividends from Heritage Oaks Bank. The availability of dividends from Heritage Oaks Bank is limited by various statutes and regulations. Heritage Oaks Bank is subject first to corporate restrictions on its ability to pay dividends. Further, Heritage Oaks Bank may not pay a dividend if it would be undercapitalized for bank regulatory purposes after the dividend payment is made. The payment of cash dividends by Heritage Oaks Bank is subject to restrictions set forth in the California Financial Code (the "Financial Code"). The Financial Code provides that a bank may not make a cash distribution to its shareholders in excess of the lesser of (a) bank's retained earnings; or (b) bank's net income for its last three fiscal years, less the amount of any distributions made by the bank or by any majority-owned subsidiary of the bank to the shareholders of the bank during such period. However, a bank may, with the approval of the California Department of Business Oversight, make a distribution to its shareholders in an

amount not exceeding the greatest of (a) its retained earnings; (b) its net income for its last fiscal year; or (c) its net income for its current fiscal year. In the event that the California Department of Business Oversight determines that the shareholders' equity of a bank is inadequate or that the making of a distribution by the bank would be unsafe or unsound, the California Department of Business Oversight may order the bank to refrain from making a proposed distribution. The FDIC may also restrict the payment of dividends if such payment would be deemed unsafe or unsound or if after the payment of such dividends, the bank would be included in one of the "undercapitalized" categories for capital adequacy purposes pursuant to federal law. While the Federal Reserve Board has no general restriction with respect to the payment of cash dividends by an adequately capitalized bank to its parent holding company, the Federal Reserve Board might, under certain circumstances, place restrictions on the ability of a particular bank to pay dividends based upon peer group averages and the performance and maturity of the particular bank, or object to management fees to be paid by a subsidiary bank to its holding company on the basis that such fees cannot be supported by the value of the services rendered or are not the result of an arm's length transaction.

        The following Unaudited Condensed Pro Forma Combined Consolidated Statements of Operations for both the nine months ended September 30, 2016 and the year ended December 31, 2015 combine the historical Consolidated Statements of Operations of Pacific Premier and the historical Consolidated Statements of Income of HEOP for such respective periods giving effect to the merger as if the merger had become effective at the beginning of the periods presented, using the acquisition method of accounting and giving effect to the pro forma adjustments described in the accompanying Notes to the Unaudited Condensed Pro Forma Combined Financial Statements.

        Although pro forma financial information is not a measurement of performance calculated in accordance with GAAP, Pacific Premier and HEOP believe that pro forma financial information is important because it gives effect to the merger and the transactions referenced above. The manner in which Pacific Premier and HEOP calculate pro forma financial information may differ from similarly titled measures reported by other companies.

        The unaudited condensed pro forma combined consolidated financial information included in this joint proxy statement/prospectus are presented for informational purposes only.

The unaudited pro forma combined financial information has been derived from and should be read in conjunction with the respective period's historical consolidated financial statements and the related notes of Pacific Premier and HEOP. The historical consolidated financial statements of Pacific Premier and HEOP are filed with the Commission and incorporated by reference into this joint proxy statement/prospectus. See "Where You Can Find More Information."

        The pro forma information, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the opportunities to earn additional revenue and does not include certain assumptions as to cost savings and, accordingly, does not attempt to predict or suggest future results. It also does not necessarily reflect what the historical results of the combined company would have been had the companies been combined during the periods presented.

Notes to Unaudited Condensed Pro Forma Combined Consolidated Financial Statements

Note A—Basis of Presentation

        The Unaudited Condensed Pro Forma Combined Consolidated Statement of Financial Condition and explanatory notes as of September 30, 2016 combines the historical Consolidated Statement of Financial Condition of Pacific Premier and the historical Consolidated Balance Sheet of HEOP as of such date (i) on an actual historical basis and (ii) assuming the completion of the merger at such date, using the acquisition method of accounting and giving effect to the related pro forma adjustments described in the accompanying Notes to the Unaudited Condensed Pro Forma Combined Consolidated Financial Statements.

        The Unaudited Condensed Pro Forma Combined Consolidated Statements of Operations and explanatory notes for both the nine months ended September 30, 2016 and the year ended December 31, 2015 combine the historical Consolidated Statements of Operations of Pacific Premier and the historical Consolidated Statements of Income of HEOP for such respective periods giving effect to the merger as if the merger had become effective at the beginning of the periods presented, using the acquisition method of accounting and giving effect to the pro forma adjustments described in the accompanying Notes to the Unaudited Condensed Pro Forma Combined Consolidated Financial Statements. The Unaudited Condensed Pro Forma Combined Consolidated Statement of Operations for the nine months ended September 30, 2016 and the year ended December 31, 2015 also gives effect to Pacific Premier's acquisition of Security California Bancorp, giving effect to the merger as if the merger had become effective at the beginning of the period using the acquisition method of accounting and giving effect to the pro forma adjustments described in the accompanying Notes to the Unaudited Pro Forma Combined Financial Statements.

        Since the merger is recorded using the acquisition method of accounting, all loans are recorded at fair value, including adjustments for credit quality, and no allowance for credit losses is carried over to Pacific Premier's balance sheet. In addition, certain anticipated nonrecurring costs associated with the merger such as professional fees, legal fees and conversion-related expenditures are not reflected in the pro forma statements of operations.

        While the recording of the acquired loans at their fair value will impact the prospective determination of the provision for credit losses and the allowance for credit losses, for purposes of the Unaudited Condensed Pro Forma Combined Consolidated Statements of Operations for the nine months ended September 30, 2016 and the year ended December 31, 2015, Pacific Premier assumed no adjustments to the historical amounts of HEOP's and Security California Bancorp's provisions for credit losses. If such adjustments were estimated, there could be an increase or a reduction to the historical amounts of HEOP's and Security California Bancorp's provisions for credit losses presented. In addition, the fair value of the loan portfolio is not necessarily reflective of the allowance for loan losses calculated under the probable incurred loss model, as the fair value also takes into account an interest and liquidity component.

Note B—Accounting Policies and Financial Statement Classifications

        The accounting policies of HEOP are in the process of being reviewed in detail by Pacific Premier. Upon completion of such review, conforming adjustments or financial statement reclassifications may be determined.

Note C—Merger and Acquisition Integration Costs

        In connection with the merger, the plan to integrate Pacific Premier's and HEOP's operations is still being developed. The specific details of this plan will continue to be refined over the next several months, and will include assessing personnel, benefit plans, premises, equipment, and service contracts

to determine where they may take advantage of redundancies. Certain decisions arising from these assessments may involve involuntary termination of employees, vacating leased premises, changing information systems, canceling contracts with certain service providers, and selling or otherwise disposing of certain furniture and equipment. Pacific Premier also expects to incur merger-related costs including professional fees, legal fees, system conversion costs and costs related to communications with customers and others. To the extent there are costs associated with these actions, the costs will be recorded based on the nature of the cost and in the period incurred.

Note D—Estimated Annual Cost Savings

        Pacific Premier expects to realize cost savings following the merger. These cost savings are not reflected in the pro forma financial information and there can be no assurance they will be achieved in the amount or manner currently contemplated.

Note E—Pro Forma Adjustments

        The following pro forma adjustments have been reflected in the unaudited pro forma combined condensed consolidated financial information. All adjustments are based on current assumptions and valuations, which are subject to change.

DESCRIPTION OF PACIFIC PREMIER CAPITAL STOCK

        The following summary of the current terms of the capital stock of Pacific Premier and the terms of capital stock of Pacific Premier to be in effect after completion of the merger is not meant to be complete and is qualified in its entirety by reference to the DGCL, federal law, the Pacific Premier amended and restated certificate of incorporation, or Pacific Premier certificate of incorporation, and the Pacific Premier amended and restated bylaws, or the Pacific Premier bylaws, copies of which have been filed with the Commission and are also available upon request from Pacific Premier. See "Where You Can Find More Information" beginning on page        .

Common Stock

        The Pacific Premier certificate of incorporation authorizes 100,000,000 shares of common stock, par value $0.01 per share. At        , 2017, there were            shares of Pacific Premier common stock issued and outstanding, held of record by approximately            shareholders. The Pacific Premier common stock is listed on the NASDAQ Global Select Market under the symbol "PPBI." The transfer agent and registrar for Pacific Premier common stock is American Stock Transfer & Trust Company.

        Each holder of Pacific Premier common stock is entitled to:

        Holders of Pacific Premier common stock are not entitled to preemptive rights and have no subscription, redemption or conversion privileges.

        The outstanding shares of Pacific Premier common stock are validly issued, fully-paid and nonassessable.

Preferred Stock

        The Pacific Premier certificate of incorporation authorizes 1,000,000 shares of preferred stock, par value $0.01 per share. As of the date of this joint proxy statement/prospectus, there were no issued and outstanding shares of Pacific Premier preferred stock.

        Under the Pacific Premier certificate of incorporation, Pacific Premier may issue shares of preferred stock in one or more series, as may be determined by the Pacific Premier board of directors. The Pacific Premier board of directors may also establish, from time to time, the number of shares to be included in each series and may fix the designation, powers, preferences and rights of the shares of each such series and any qualifications, limitations or restrictions thereof, and may increase or decrease the number of shares of any series without any further vote or action by the shareholders. Any preferred stock that Pacific Premier may issue will rank senior to Pacific Premier common stock with respect to the payment of dividends or amounts paid upon liquidation, dissolution or winding up of Pacific Premier, or both. In addition, any shares of Pacific Premier preferred stock may have class or series voting rights. Under certain circumstances, the issuance of shares of Pacific Premier preferred stock, or merely the existing authorization of the Pacific Premier board of directors to issue shares of Pacific Premier preferred stock, may tend to discourage or impede a merger or other change in control

133


Table of Contents

of Pacific Premier. No shares of preferred stock are currently outstanding. Each series of preferred stock, to the extent issued, will be issued under a separate certificate of designation.

Anti-takeover Provisions

Delaware Anti-Takeover Law.

        As a Delaware corporation, Pacific Premier is subject to Section 203 of the DGCL, which generally prevents an interested shareholder, defined generally as a person owning 15% or more of a corporation's outstanding voting stock, from engaging in a business combination with Pacific Premier for three (3) years following the date that person became an interested shareholder, unless certain specified conditions are satisfied. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by the Pacific Premier board of directors, including discouraging attempts that might result in a premium over the market price for the shares of Pacific Premier common stock held by shareholders.

Possible Future Issuance of Preferred Stock.

        The Pacific Premier board of directors can at any time issue one or more new series of preferred stock pursuant to the Pacific Premier certificate of incorporation and without shareholder approval. In some cases, the issuance of preferred stock could discourage or make more difficult attempts to take control of Pacific Premier through a merger, tender offer, proxy context or otherwise. Shares of Pacific Premier preferred stock with special voting rights or other features issued to persons favoring Pacific Premier's management could stop a takeover by preventing the person trying to take control of Pacific Premier from acquiring enough voting shares to take control.

Removal and Vacancies on the Board of Directors.

        Subject to the rights of the holders of any series of Pacific Premier preferred stock then outstanding, directors may be removed by Pacific Premier's shareholders, with or without cause, by the affirmative vote of at least 662/3% of the voting power of all of the then-outstanding shares of capital stock of Pacific Premier entitled to vote generally in the election of directors, voting together as a single class. Further, any newly created directorships resulting from any increase in the authorized number of directors or any vacancies on the board resulting from death, resignation, retirement, removal or other cause may be filled only by a majority vote of the directors then in office, whether or not a quorum is present. These provisions may deter a shareholder from removing incumbent directors and from simultaneously gaining control of the board of directors by filling the resulting vacancies with its own nominees. Consequently, the existence of these provisions may have the effect of deterring hostile takeovers, which could depress the market price of Pacific Premier common stock.

Advance Notice Requirements for Shareholder Proposals and Director Nominations.

        The Pacific Premier bylaws provide that shareholders seeking to nominate candidates for election as directors or to bring business before an annual meeting of shareholders must provide timely notice of their proposal in writing to the corporate secretary. Generally, to be timely, a shareholder's notice must be received at Pacific Premier's principal executive offices not less than ninety (90) days nor more than one hundred twenty (120) days prior to the first anniversary date of the previous year's annual meeting. The Pacific Premier bylaws also specify requirements as to the form and content of a shareholder's notice. The Pacific Premier bylaws also provide that notice may be provided by shareholders to Pacific Premier in accordance with the Commission's rules. These provisions may impede shareholders' ability to bring matters before an annual meeting of shareholders or make nominations for directors at an annual meeting of shareholders.

134


Table of Contents

Additional Provisions in the Pacific Premier Certificate of Incorporation and Bylaws.

        The Pacific Premier certificate of incorporation and the Pacific Premier bylaws contain additional provisions that may be deemed to have the effect of discouraging or delaying attempts to gain control of Pacific Premier, including provisions that provide: (i) the board of directors with the exclusive power to fix from time to time the size of the board; (ii) for any action required or permitted to be taken by Pacific Premier shareholders to be taken only at an annual or special meeting and prohibit shareholder action by written consent in lieu of a meeting; (iii) for special meetings of shareholders to be called only by the board of directors; and (iv) for certain of the foregoing provisions to be amended only by the affirmative vote of at least 662/3% of the voting power of all of the then-outstanding shares of capital stock of Pacific Premier entitled to vote generally in an election of directors, voting together as a single class.

Restrictions on Ownership

        The BHC Act generally prohibits any company that is not engaged in banking activities and activities that are permissible for a bank holding company or a financial holding company from acquiring control of a bank holding company, such as Pacific Premier. "Control" is generally defined as ownership of 25% or more of the voting stock or other exercise of a controlling influence. Any existing bank holding company would need the prior approval of the Federal Reserve before acquiring 5% or more of the voting stock of Pacific Premier. In addition, the Change in Bank Control Act of 1978, as amended, prohibits a person or group of persons from acquiring control of a bank holding company unless the Federal Reserve has been notified and has not objected to the transaction. Under a rebuttable presumption established by the Federal Reserve, the acquisition of 10% or more of a class of voting stock of a bank holding company with a class of securities registered under Section 12 of the Exchange Act, such as Pacific Premier, could constitute acquisition of control of the bank holding company.


COMPARISON OF THE RIGHTS OF SHAREHOLDERS

        When the merger becomes effective, shareholders of HEOP who receive shares of Pacific Premier common stock in exchange for their shares of HEOP common stock will become shareholders of Pacific Premier. Pacific Premier is a Delaware corporation and the rights of Pacific Premier shareholders are governed by the DGCL, as well as the Pacific Premier certificate of incorporation and the Pacific Premier bylaws. HEOP is a California corporation, and its shareholders' rights are governed by the CGCL and the HEOP articles of incorporation and HEOP bylaws.

        After the merger, as Pacific Premier shareholders, the rights of former HEOP shareholders will be governed by the Pacific Premier certificate of incorporation, the Pacific Premier bylaws and the DGCL. The following is a summary of material differences between the rights of holders of Pacific Premier common stock and holders of HEOP common stock. The summary does not purport to be a complete statement of the provisions affecting, and differences between, the rights of holders of Pacific Premier common stock and holders of HEOP common stock. Rather, the summary is intended to provide a general overview of the differences in shareholders' rights under the governing corporate instruments of Pacific Premier and HEOP, and other known material differences.

Issuance of Capital Stock

Pacific Premier.

        Under the Pacific Premier certificate of incorporation and the DGCL, Pacific Premier may issue shares of Pacific Premier capital stock and rights or options for the purchase of shares of capital stock of Pacific Premier on such terms and for such consideration as may be determined by the Pacific Premier board of directors. None of the DGCL, the Pacific Premier certificate of incorporation or the Pacific Premier bylaws require shareholder approval of any such actions. Pacific Premier may, however, elect to seek shareholder approval of stock-related compensation plans in certain instances in order to qualify such plans for favorable federal income tax treatment and to comply with the continued listing rules of the NASDAQ Global Select Market and securities laws treatment under current laws and regulations. Holders of Pacific Premier common stock do not have preemptive rights with respect to any shares of Pacific Premier capital stock which may be issued.

HEOP.

        Under the CGCL, HEOP may issue shares of HEOP stock for such consideration as may be determined by the HEOP board of directors in accordance with the CGCL.

136


Table of Contents

HEOP.

        On any matter other than elections of directors, any holder of HEOP common stock may vote part of the shares of HEOP common stock in favor of the proposal and refrain from voting the remaining shares or vote them against the proposal, but, if the holder of HEOP common stock fails to specify the number of shares which the shareholder is voting affirmatively, it will be conclusively presumed that the shareholder's approving vote is with respect to all shares that the shareholder is entitled to vote. If a quorum is present, the affirmative vote of the majority of the shares of HEOP common stock represented at the meeting and entitled to vote on any matter (other than the election of directors) shall be the act of the shareholders, unless the vote of a greater number or voting by classes is required by the CGCL or by the articles of incorporation. Pursuant to the HEOP bylaws, with respect to the election of directors, holders of HEOP stock have cumulative voting rights if the candidates' names have been placed in nomination prior to the voting, and at least one shareholder has given notice at the meeting, prior to the voting, of that shareholder's intention to cumulate that shareholder's votes. The candidates receiving the highest number of votes of the shares entitled to be voted for them, up to the number of directors to be elected by such shares, are elected.

Number and Election of Directors

Pacific Premier.

        The Pacific Premier bylaws provide that the number of directors who constitute the board of directors is such number as the board of directors from time to time has designated, except that in the absence of such designation, such number is seven (7). The directors are elected by the shareholders each year at the annual meeting of shareholders and hold office until the next annual meeting and until each director's successor has been duly elected and qualified or until a director's earlier resignation or removal. Currently, Pacific Premier's board of directors consists of ten (10) directors.

HEOP.

        HEOP's bylaws provide that the number of directors comprising the board of directors will be from seven (7) to thirteen (13), with the exact number to be determined from time to time by the board of directors. There are currently eleven (11) members of the HEOP board of directors. The directors are elected by the shareholders each year at the annual meeting of shareholders and hold office until the next annual meeting and until each director's successor has been duly elected and qualified or until a director's earlier resignation or removal.

Removal of Directors

Pacific Premier.

        Under the DGCL, directors may be removed, with or without cause, by the holders of a majority of the shares entitled to vote, unless a greater vote is required by the certificate of incorporation or the bylaws. Under the Pacific Premier certificate of incorporation, subject to the rights of holders of any series of preferred stock then outstanding, any director, or the entire board of directors, may be removed from office at any time with or without cause by the affirmative vote of the holders of at least 662/3% of the voting power of all of the then-outstanding shares of capital stock of Pacific Premier entitled to vote generally in an election of directors, voting together as a single class.

137


Table of Contents

Vacancies of Directors

Pacific Premier.

        The DGCL provides that, unless the certificate of incorporation or bylaws provide otherwise, a majority of the directors then in office (although less than a quorum) or the sole remaining director may fill any vacancy on a board of directors, including newly created directorships resulting from an increase in the number of directors. Under the Pacific Premier bylaws, subject to the rights of holders of any series of preferred stock outstanding, any vacancy occurring on its board of directors may be filled by a majority vote of the directors then in office, whether or not a quorum is present. Each director so chosen will hold office until the next annual meeting of shareholders.

HEOP.

        HEOP's bylaws provide that, except for a vacancy caused by the removal of a director, vacancies on the board may be filled by a majority of the directors then in office, whether or not they constitute a quorum, or by a sole remaining director. A vacancy on the board caused by the removal of a director may be filled only by the shareholders, except that a vacancy created when the board declares the office of a director vacant because a director has been convicted of a felony or declared of unsound mind by an order of court may be filled by the board of directors. The shareholders may elect a director at any time to fill a vacancy not filled by the board of directors. The term of office of a director elected to fill a vacancy runs until the next annual meeting of the shareholders, and such a director holds office until a successor is elected and qualified.

Indemnification and Limitation of Liability

Pacific Premier.

        The DGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. A similar standard is applicable in the case of derivative actions, except that indemnification extends only to expenses (including attorneys' fees) incurred in connection with the defense or settlement of such action, and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation.

        The DGCL provides that any indemnification must be made by the corporation only as authorized in the specific case upon a determination that indemnification is proper in the circumstances because the person has met the applicable standard of conduct. Such determination must be made, with respect to a person who is a director or officer at the time of such determination, (i) by a majority vote of the directors who are not parties to the action, suit or proceeding, even though less than a quorum, or (ii) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (iv) by the shareholders.

138


Table of Contents

        The DGCL provides that it is not exclusive of other indemnification that may be granted by a corporation's bylaws, disinterested director vote, shareholder vote, agreement or otherwise.

        The Pacific Premier certificate of incorporation provides for the indemnification of directors, officers and certain of its authorized representatives to the fullest extent permitted by the DGCL, except that indemnification in an action, suit or proceeding initiated by a director, officer or authorized representative is permitted only if the board of directors authorized the initiation of that action, suit or proceeding. In addition, as permitted by the DGCL, the Pacific Premier certificate of incorporation provides that the directors shall have no personal liability to Pacific Premier or its shareholders for monetary damages for breach of fiduciary duty as a director, except (i) for any breach of the director's duty of loyalty to Pacific Premier or its shareholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or knowing violation of the law, (iii) the unlawful payment of dividends or unlawful stock purchase or redemption, or (iv) for any transaction in which the director derived improper personal benefit.

HEOP.

        The CGCL permits a corporation to indemnify any person who was, is, or is threatened to be made a party to a proceeding, by reason of the fact that the person is or was an agent of the corporation (defined as any person who is or was a director, officer, employee or other agent of the corporation or its predecessor, or is or was serving at the request of the corporation or its predecessor as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise), against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred in connection with the proceeding if that person acted in good faith and in a manner the person reasonably believed to be in the best interests of the corporation and, in the case of a criminal proceeding, had no reasonable cause to believe the conduct of the person was unlawful. A similar standard is applicable in the case of derivative actions, except that court approval of the settlement is required before there can be any indemnification where such action has been settled, and court approval of indemnification is required where the person seeking indemnification has been found liable to the corporation.

        Pursuant to the CGCL, expenses incurred in defending any proceeding may be advanced by the corporation prior to the final disposition of the proceeding upon receipt of an undertaking by or on behalf of the agent to repay that amount if the agent is ultimately determined to not be entitled to indemnification.

        The CGCL provides that it is not exclusive of other indemnification that may be granted by a corporation's bylaws, disinterested director vote, shareholder vote, agreement or otherwise to the extent the additional rights to indemnification are authorized in the articles of incorporation. HEOP's articles of incorporation authorize it to provide indemnification of its officers, directors, and other agents for breach of duty to the corporation and its shareholders through bylaw provisions, agreements with agents, or otherwise, in excess of the indemnification otherwise permitted by Section 317 of the CGCL, subject to the limits set forth in Section 204 of the CGCL. HEOP's bylaws provide that it may, to the maximum extent permitted by the CGCL, indemnify its directors, officers, and other agents in connection with any proceeding arising by reason of the fact that any such person is or was an agent of the corporation, and that it may advance to each such agent expenses incurred in defending any such proceeding to the maximum extent permitted by the law.

        Under the CGCL, a subject corporation may, through its articles of incorporation, eliminate or limit the personal liability of a director for monetary damages in an action brought by or in the right of the corporation for breach of a director's duties to the corporation and its shareholders, except (i) for acts or omissions that involve intentional misconduct or knowing and culpable violation of the law, (ii) for acts or omissions not in good faith or that a director believes to be contrary to the best interests

139


Table of Contents

of the corporation or its shareholders, (iii) for any transaction from which a director derived an improper personal benefit, (iv) for acts or omissions that show a reckless disregard for the director's duty to the corporation or its shareholders in circumstances in which the director was aware, or should have been aware, in the ordinary course of performing a director's duties, of a risk of serious injury to the corporation or its shareholders, (v) for acts or omissions that constitute an unexcused pattern of inattention that amounts to an abdication of the director's duty to the corporation or its shareholders, (vi) for any contract or other transaction between HEOP, on the one hand, and one or more of HEOP's directors or any corporation, firm or association in which one or more of its directors has a material financial interest or for which such director or directors also serve as a director, on the other hand, which transaction is not otherwise approved in accordance with the CGCL, or (vii) for the unlawful payment of dividends, distribution of assets to shareholders after institution of dissolution proceedings, or the unlawful making of any loan or guaranty. The HEOP articles of incorporation eliminate the liability of the directors of HEOP for monetary damages to the fullest extent permissible under California law.

Amendments to Articles of Incorporation and Bylaws

Pacific Premier.

        The DGCL provides that an amendment to a Delaware corporation's certificate of incorporation requires a board resolution stating the advisability of the amendment and approval by a majority of the holders of outstanding capital stock of each class entitled to vote thereon. The Pacific Premier certificate of incorporation provides that amendments to the Pacific Premier certificate of incorporation may be effected in the manner prescribed by the DGCL; provided, however, that the amendment of Sections C or D of Article Fifth, Article Sixth, Article Seventh, Article Ninth and Article Eleventh requires the affirmative vote of the holders of at least 662/3% of the voting power of all of the then-outstanding shares of the capital stock of Pacific Premier entitled to vote generally in the election of directors, voting together as a single class.

        The Pacific Premier bylaws authorize Pacific Premier's board of directors to amend its bylaws by vote of a majority of the board of directors at a meeting. The Pacific Premier bylaws may also be amended by the affirmative vote of the holders of at least 662/3% of the voting power of all of the then-outstanding shares of the capital stock of Pacific Premier entitled to vote generally in the election of directors, voting together as a single class.

HEOP.

        Subject to certain exceptions, the CGCL provides that amendments to a California corporation's articles of incorporation must be approved by the board of directors and by a majority of the corporation's outstanding shares, either before or after approval by the board of directors.

        HEOP's articles of incorporation may be amended in any manner allowed under California law.

        HEOP's bylaws may be amended or repealed, and new bylaws may be adopted, by the board of directors or by the holders of a majority of the outstanding shares entitled to vote, except as otherwise required by law or by the articles of incorporation.

Notice of Shareholder Meetings

Pacific Premier.

        In accordance with the DGCL, the Pacific Premier bylaws provide that a written notice of the time, date, and place of all shareholder meetings must be given to each shareholder entitled to vote at the meeting not less than ten (10) days nor more than sixty (60) days prior to the meeting.

140

Special Meetings of Shareholders

Pacific Premier.

        Pursuant to the DGCL, a special meeting of shareholders may be called by a corporation's board of directors or by the persons authorized to do so in the corporation's certificate of incorporation or bylaws. The Pacific Premier certificate of incorporation provides that a special meeting of shareholders may be called only by the board of directors pursuant to a resolution adopted by the majority of the total number of authorized directorships or as otherwise provided in the bylaws. The Pacific Premier bylaws provide that, subject to the rights of the holders of preferred stock, special meetings of shareholders may be called only by the board of directors pursuant to a resolution adopted by a majority of the total number of directors which the corporation would have if there were no vacancies on the board of directors.

HEOP.

        Under HEOP's bylaws, a special meeting of the shareholders may be called at any time by the board of directors, or by the chairman of the board, or by the president, or by one or more shareholders holding shares in the aggregate entitled to cast not less than ten percent (10%) of the votes at that meeting. Pursuant to the CGCL, shareholders requesting a special meeting must do so by submitting their request, in writing, to the chairperson of HEOP's board of directors or to HEOP's president, vice president or secretary. Pursuant to HEOP's bylaws, every special meeting of HEOP shareholders, unless otherwise required by law, must be called by mailing, postage prepaid, to each shareholder at the address appearing on HEOP's books, a notice stating the purpose of the special meeting not less than thirty-five (35) days nor more than sixty (60) days after the receipt of the request. If the notice is not given within twenty (20) days after receipt of the request, the person or persons requesting the meeting may give the notice.

Shareholder Nominations and Shareholder Proposals

Pacific Premier.

        The Pacific Premier bylaws provide that shareholders of Pacific Premier may nominate one or more persons for election as director only if such nominations are delivered to the secretary of Pacific Premier at the principal executive offices of the corporation not earlier than the close of business on the one hundred twentieth (120th) day and not later than the close of business on the ninetieth (90th) day prior to the first anniversary of the preceding year's annual meeting; provided, however, that in the event that the date of the annual meeting is more than thirty (30) days before or more than sixty (60) days after such anniversary date, notice by the shareholder to be timely must be so delivered not earlier than the close of business on the one hundred twentieth (120th) day prior to the date of such annual meeting and not later than the close of business on the later of the ninetieth (90th) day prior to the date of such annual meeting or, if the first public announcement of the date of such annual meeting is less than one hundred (100) days prior to the date of such annual meeting, the tenth (10th) day following the day on which public announcement of the date of such meeting is first made by the corporation. Each such notice must set forth information concerning the nominee, the nominating shareholder and the other information specified in the Pacific Premier bylaws. The Pacific Premier bylaws provide that a proposal by shareholders for submission to a vote of shareholders at an annual meeting must be delivered to the secretary of Pacific Premier within the same time frame as

141


Table of Contents

shareholder nominations for directors described above. Each such notice must set forth information concerning the proposal, the proposing shareholder and the information specified in the Pacific Premier bylaws.

HEOP.

        HEOP's bylaws do not provide for the nomination of director candidates by shareholders. Neither the CGCL nor the HEOP articles of incorporation or bylaws specifically address shareholder proposals.

Shareholder Action by Written Consent

Pacific Premier.

        The Pacific Premier bylaws provide that, subject to the rights of the holders of any class or series of preferred stock, any action required or permitted to be taken by the shareholders of Pacific Premier must be effected at an annual or special meeting of shareholders and may not be effected by any consent in writing by such shareholders.

HEOP.

        Under HEOP's bylaws, any action which may be taken at any annual or special meeting of shareholders may be taken without a meeting and without prior notice, if a consent in writing is signed by the holders of outstanding shares having not less than the minimum number of votes that would be necessary to authorize or take that action at a meeting at which all shares entitled to vote on that action were present and voted, except that unanimous written consent is required for election of directors to non-vacant positions.

Transactions with Interested Persons

Pacific Premier.

        The DGCL prohibits a corporation from engaging in any business combination with an interested shareholder (defined as a 15% shareholder) for a period of three (3) years after the date that shareholder became an interested shareholder, unless (i) before that date, the board of directors of the corporation approved the business combination or the transaction in which the shareholder became an interested shareholder, (ii) upon completion of the transaction that resulted in the shareholder becoming an interested shareholder, the shareholder owned at least 85% of the outstanding voting stock (excluding shares owned by directors, officers and certain employee stock ownership plans) or (iii) on or after the date the shareholder became an interested shareholder, the business combination received the approval of both the corporation's directors and holders of two-thirds of the outstanding voting shares not owned by the interested shareholder voted at a meeting and not by written consent. A Delaware corporation may opt out of this provision through an amendment to its certificate of incorporation or bylaws adopted by a majority of the outstanding voting shares. The Pacific Premier certificate of incorporation expressly provides that it is bound by this provision of the DGCL concerning transactions with interested shareholders.

HEOP.

        Under the CGCL, contracts between a corporation and one or more of its directors, or between a corporation and any corporation, firm or association in which one or more of its directors has a material financial interest are not void or voidable because such director or directors or such other corporation, firm or association are parties or because such director or directors are present at the meeting of the board or a committee thereof which authorizes, approves or ratifies the contract or transaction, if: (i) the material facts as to the transaction and as to such director's interest are fully

142


Table of Contents

disclosed or known to the shareholders and such contract or transaction is approved by the shareholders in good faith, with the shares owned by the interested director or directors not being entitled to vote thereon; (ii) the material facts as to the transaction and as to such director's interest are fully disclosed or known to the board or committee, and the board or committee authorizes, approves or ratifies the contract or transaction in good faith by a vote sufficient without counting the vote of the interested director or directors and the contract or transaction is just and reasonable as to the corporation at the time it is authorized, approved or ratified; or (iii) the person asserting the validity of the contract or transaction sustains the burden of proving that the contract or transaction was just and reasonable as to the corporation at the time it was authorized, approved or ratified.

Dividends

Pacific Premier.

        The DGCL permits a Delaware corporation to declare and pay dividends out of surplus or, if there is no surplus, out of net profits for the fiscal year in which the dividend is declared and/or for the preceding fiscal year as long as the amount of capital of the corporation following the declaration and payment of the dividend is not less than the aggregate amount of the capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets. Further, it is the policy of the Federal Reserve that bank holding companies, such as Pacific Premier, should generally pay dividends on common stock only out of income available over the past year, and only if prospective earnings retention is consistent with the organization's expected future needs and financial condition. It is also the Federal Reserve's policy that bank holding companies should not maintain dividend levels that undermine their ability to be a source of strength to their banking subsidiaries. The Pacific Premier bylaws permit its board of directors to declare dividends, but it is Pacific Premier's policy to retain earnings to provide funds for use in its business. Pacific Premier has never declared or paid dividends on its common stock and does not anticipate declaring or paying any cash dividends in the foreseeable future.

HEOP.

        The CGCL permits a California corporation to declare and pay dividends if the amount of retained earnings of the corporation immediately prior to the dividend payment exceeds the sum of the proposed dividend distribution plus the amount, if any, of cumulative dividends in arrears on all shares having a preference with respect to payment of dividends over the class or series to which the applicable dividend is being made. The CGCL also requires that a corporation's assets equal or exceed the sum of its total liabilities plus the amount that would be needed if the corporation were to be dissolved at the time of the dividend to satisfy the preferential rights, including accrued but unpaid dividends, of other shareholders upon dissolution that are superior to the rights of the shareholders receiving the dividend. The CGCL also prohibits dividend distributions if either the corporation or any of its subsidiaries would be unable to meet liabilities as they mature. It is the policy of the Federal Reserve that bank holding companies, such as HEOP, should generally pay dividends on common stock only out of income available over the past year, and only if prospective earnings retention is consistent with the organization's expected future needs and financial condition. It is also the Federal Reserve's policy that bank holding companies should not maintain dividend levels that undermine their ability to be a source of strength to its banking subsidiaries.

        HEOP has declared and paid quarterly dividends on its common stock and is permitted by the merger agreement to continue to pay quarterly dividends equal to the rate paid during the fiscal quarter immediately preceding the date of the merger agreement.

Shareholders' Right of Dissent and Appraisal

Pacific Premier.

        Under the DGCL, shareholders are generally entitled to dissent from a merger or consolidation and obtain payment of the fair value of their shares when a merger or consolidation of business entities occurs. However, the DGCL provides that appraisal rights are not available with respect to any class or series to stock that is either listed on a national securities exchange or held of record by more than 2,000 holders, unless, under the terms of the transaction, holders are required to accept anything other than shares of publicly traded stock of the acquirer and/or cash in lieu of fractional shares. Pacific Premier's common stock is listed on a national securities exchange, and as such, Pacific Premier's shareholders are not entitled to appraisal rights.

HEOP.

        Under the CGCL, shareholders are generally entitled to dissent from a merger or consolidation and obtain payment of the fair value of their shares when a merger or consolidation occurs. However, the CGCL provides that appraisal rights are not available for shares that are listed on a national securities exchange where the merger consideration is stock of a publicly traded corporation. HEOP's common stock is traded on a national security exchange and the merger consideration, comprised of Pacific Premier's common stock, is also traded on a national securities exchange. As such, HEOP's shareholders are not entitled to appraisal rights.


LEGAL MATTERS

        The validity of the Pacific Premier common stock to be issued in the merger has been passed upon for Pacific Premier by Holland & Knight LLP, Washington, D.C. As of                        , 2017, attorneys employed by that law firm beneficially owned approximately                shares of Pacific Premier common stock.


EXPERTS

        Pacific Premier's consolidated financial statements incorporated into this joint proxy statement/prospectus by reference to its Annual Report on Form 10-K for the year ended December 31, 2015 have been so incorporated in reliance on the report of Vavrinek, Trine, Day and Co., LLP, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting..

        HEOP's consolidated financial statements incorporated into this joint proxy statement/prospectus by reference to its Annual Report on Form 10-K for the year ended December 31, 2015 have been so incorporated in reliance on the report of Crowe Horwath LLP, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.

HOUSEHOLDING

        The SEC has adopted rules that permit companies and intermediaries, such as brokers, to satisfy delivery requirements for proxy statements with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as "householding," potentially provides extra convenience for stockholders and cost savings for companies. Pacific Premier and HEOP will mail only one copy of the joint proxy statement/prospectus to multiple shareholders sharing the same address. Once you have received notice from your broker, Pacific Premier or HEOP that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate joint

Shareholders that intend to present a proposal at the Pacific Premier 2017 annual meeting of shareholders, but not to include the proposal in Pacific Premier's proxy statement for that meeting, must give notice of the proposal to the Pacific Premier Secretary no sooner than January 31, 2017, which is one hundred twenty (120) days prior to May 31, 2017, which is the one-year anniversary of the Pacific Premier 2016 annual meeting of shareholders, but no later than February 28, 2017, which is ninety (90) days prior to May 31, 2017 (the one-year anniversary of the 2016 annual meeting). As set forth in the Pacific Premier bylaws, the shareholder's notice to the Secretary must contain certain required information. If the scheduled date for the 2017 annual meeting of shareholders is changed by more than 30 days, shareholders will be informed of the new meeting date and the revised date by which shareholder proposals must be received. We strongly encourage any shareholder interested in submitting a proposal to consult knowledgeable counsel with regard to the detailed requirements of applicable securities laws.

        Pursuant to the Pacific Premier bylaws, any matter to be presented at the Pacific Premier 2017 annual meeting of shareholders must be proper business to be transacted at the annual meeting or a proper nomination to be decided on at the annual meeting and must have been properly brought before such meeting pursuant to the Pacific Premier bylaws.

A-56


Table of Contents

        Any amount that becomes payable pursuant to this Section 8.02(b) shall be paid by wire transfer of immediately available funds to an account designated by PPBI. Under no circumstances shall HEOP be obligated to pay the entire Termination Fee on more than one occasion, and the parties hereby acknowledge and agree that in the event the entire Termination Fee becomes payable and is paid by HEOP pursuant to this Section 8.02, the Termination Fee shall be PPBI's sole and exclusive remedy under this Agreement.

pay the costs and expenses (including reasonable legal fees and expenses) incurred by PPBI in connection with any action, including the filing of any lawsuit, taken to collect payment of such amounts, provided PPBI prevails on the merits, together with interest on the amount of any such unpaid amounts at the prime lending rate prevailing during such period as published in The Wall Street Journal, calculated on a daily basis from the date such amounts were required to be paid until the date of actual payment.

ARTICLE IX

MISCELLANEOUS

        9.01    Survival.    No representations, warranties, agreements and covenants contained in this Agreement shall survive the Effective Time (other than agreements or covenants contained herein that by their express terms are to be performed after the Effective Time) or the termination of this Agreement if this Agreement is terminated prior to the Effective Time (other than Sections 6.06(c), 8.02 and this Article IX, which shall survive any such termination). Notwithstanding anything in the foregoing to the contrary, no representations, warranties, agreements and covenants contained in this Agreement shall be deemed to be terminated or extinguished so as to deprive a party hereto or any of its affiliates of any defense at law or in equity which otherwise would be available against the claims of any Person, including without limitation any shareholder or former shareholder.

        9.02    Waiver; Amendment.    Prior to the Effective Time, any provision of this Agreement may be (i) waived, by the party benefited by the provision or (ii) amended or modified at any time, by an agreement in writing among the parties hereto executed in the same manner as this Agreement, except that after the approval of the principal terms of this Agreement by the HEOP shareholders, no amendment shall be made which by law requires further approval by the shareholders of HEOP without obtaining such approval. For purposes of clarification, an amendment of any date in Section 8.01(c) shall not require further approval by any shareholders and if such amendment were deemed by law to require further approval by the shareholders of HEOP, the approval of the principal terms of this Agreement by the HEOP shareholders will be deemed to have granted HEOP the authority to amend such dates without such further approval.

        9.03    Counterparts.    This Agreement may be executed in one or more counterparts, all of which shall be deemed to constitute one and the same original agreement.

        9.04    Governing Law.    This Agreement shall be governed by, and interpreted in accordance with, the laws of the State of Delaware applicable to contracts made and to be performed entirely within such State.

        9.06    Notices.    All notices, requests and other communications hereunder to a party shall be in writing and shall be deemed given if personally delivered, telecopied (with confirmation) or mailed by registered or certified mail (return receipt requested) or delivered by an overnight courier (with confirmation) to such party at its address set forth below or such other address as such party may specify by notice to the parties hereto.

        9.07    Entire Understanding; Limited Third Party Beneficiaries.    This Agreement, the Bank Merger Agreement, the Shareholder Agreements, and the Confidentiality Agreement represent the entire understanding of the parties hereto and thereto with reference to the Transaction, and this Agreement, the Bank Merger Agreement, the Shareholder Agreements, and the Confidentiality Agreement supersede any and all other oral or written agreements heretofore made. Except for the Indemnified Parties' right to enforce PPBI's obligation under Section 6.10, which are expressly intended to be for the irrevocable benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives, nothing in this Agreement, expressed or implied, is intended to confer upon any Person, other than the parties hereto or their respective successors, any rights, remedies, obligations or liabilities under or by reason of this Agreement.

        9.08    Severability.    Except to the extent that application of this Section 9.08 would have a Material Adverse Effect on HEOP or PPBI, any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable. In all such

cases, the parties shall use their reasonable best efforts to substitute a valid, legal and enforceable provision which, insofar as practicable, implements the original purposes and intents of this Agreement.

Except as provided in Section 8.02(b), it is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity. In the event attorneys' fees or other costs are incurred to secure performance of any of the obligations herein provided for, or to establish damages for the breach thereof, or to obtain any other appropriate relief, whether by way of prosecution or defense, the prevailing party shall be entitled to recover reasonable attorneys' fees and costs incurred therein.

        9.10    Interpretation.    When a reference is made in this Agreement to Sections, Exhibits or Schedules, such reference shall be to a Section of, or Exhibit or Schedule to, this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and are not part of this Agreement. Whenever the words "include," "includes" or "including" are used in this Agreement, they shall be deemed to be followed by the words "without limitation." Whenever the words "as of the date hereof" are used in this Agreement, they shall be deemed to mean the day and year first above written.

        9.11    Assignment.    No party may assign either this Agreement or any of its rights, interests or obligations hereunder without the prior written approval of the other parties. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

        9.12    Alternative Structure.    Notwithstanding any provision of this Agreement to the contrary, PPBI may at any time modify the structure of the acquisition of HEOP set forth herein, provided that (i) the Merger Consideration to be paid to the holders of HEOP Common Stock is not thereby changed in kind or reduced in amount as a result of such modification, (ii) such modifications will not adversely affect the tax treatment to HEOP's shareholders as a result of receiving the Merger Consideration and (iii) such modification will not jeopardize receipt of any required approvals of Governmental Authorities or delay consummation of the Transactions contemplated by this Agreement.

ANNEX A

SHAREHOLDER AGREEMENT

        SHAREHOLDER AGREEMENT (this "Agreement"), dated as of December     , 2016, among                        , a shareholder ("Shareholder") of Heritage Oaks Bancorp, a California corporation ("HEOP"), Pacific Premier Bancorp, Inc., a Delaware corporation ("PPBI"), and, solely for purposes of the last sentence of Section 9, HEOP. All terms used herein and not defined herein shall have the meanings assigned thereto in the Merger Agreement (defined below).

        WHEREAS, HEOP and PPBI are entering into an Agreement and Plan of Reorganization, dated as of the date hereof (the "Merger Agreement"), pursuant to which HEOP will merge with and into PPBI on the terms and conditions set forth therein (the "Merger") and, in connection therewith, outstanding shares of HEOP Common Stock will be converted into shares of PPBI Common Stock in the manner set forth therein; and

        WHEREAS, Shareholder owns the shares of HEOP Common Stock identified on Exhibit I hereto (such shares, together with all shares of HEOP Common Stock subsequently acquired by Shareholder during the term of this Agreement, being referred to as the "Shares"); and

        WHEREAS, in order to induce PPBI to enter into the Merger Agreement, Shareholder, solely in such Shareholder's capacity as a shareholder of HEOP and not in any other capacity, has agreed to enter into and perform this Agreement.

        NOW, THEREFORE, for good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

        1.    Agreement to Vote Shares.    Shareholder agrees while this Agreement is in effect, that at any meeting of the shareholders of HEOP, or in connection with any written consent of the shareholders of HEOP, Shareholder shall:

        2.    Transfer of Shares.

        3.    Representations and Warranties of Shareholder.    Shareholder represents and warrants to and agrees with PPBI as follows:

        4.    No Solicitation.    Shareholder hereby agrees that during the term of this Agreement he, she or it shall not, and shall not permit any investment banker, financial advisor, attorney, accountant or other representative retained by him, her or it to, directly or indirectly, (a) take any of the actions specified in clauses (i)-(vi) of Section 6.07(a) of the Merger Agreement, (b) agree to release, or release, any Person from any obligation under any existing standstill agreement or arrangement relating to HEOP, or (c) participate in, directly or indirectly, a "solicitation" of "proxies" (as such terms are used in the rules of the SEC) or powers of attorney or similar rights to vote, or seek to advise or influence any Person with respect to the voting of, any shares of HEOP Common Stock in connection with any vote or other action on any matter of a type described in Section 1(b), other than to recommend that shareholders of HEOP vote in favor of the adoption and approval of the Merger Agreement and the Merger and as otherwise expressly permitted by this Agreement. Shareholder agrees immediately to cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any Persons other than PPBI with respect to any possible Acquisition Proposal and will take all necessary steps to inform any investment banker, financial advisor, attorney, accountant or other representative retained by him, her or it of the obligations undertaken by Shareholder pursuant to this Section 4. Nothing contained in this Section 4 shall prevent a Shareholder who is an officer or a member of the HEOP Board from discharging his or her fiduciary duties solely in his or her capacity as such an officer or director.

        5.    Notice of Acquisitions; Proposals Regarding Prohibited Transactions.    Shareholder hereby agrees to notify PPBI promptly (and in any event within two (2) Business Days) in writing of the number of any additional shares of HEOP Common Stock or other securities of HEOP of which Shareholder acquires beneficial or record ownership on or after the date hereof. Shareholder will comply with the provisions of Section 6.07(b) of the Merger Agreement as if he, she or it were HEOP.

        6.    Non-Solicitation.    

A-A-3

        7.    Specific Performance and Remedies.    Shareholder acknowledges that it will be impossible to measure in money the damage to PPBI if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, PPBI will not have an adequate remedy at law. Accordingly, Shareholder agrees that injunctive relief or other equitable remedy, in addition to remedies at law or in damages, is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that PPBI may have an adequate remedy at law. Shareholder agrees that Shareholder will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with PPBI's seeking or obtaining such equitable relief.

HEOP agrees that it shall comply with such stop transfer instructions.

This Agreement may not be amended, supplemented or modified, and no provisions hereof may be modified or waived, except by an instrument in writing signed by each party hereto.

Board of Directors
Pacific Premier Bancorp, Inc.
17901 Von Karman Avenue, Suite 1200
Irvine, CA 92614

Members of the Board:

        We understand that Pacific Premier Bancorp, Inc. ("Parent") and Pacific Premier Bank, a wholly owned subsidiary of Parent (the "Bank") propose to enter into an Agreement and Plan of Reorganization (the "Agreement") with Heritage Oaks Bancorp (the "Company") pursuant to which, among other things, Company will merge with and into the Parent (the "Transaction") and each outstanding share of the common stock of the Company (the "Company Common Stock") issued and outstanding immediately prior to the Effective Time (including any shares that were issued as restricted stock and for which the vesting conditions have been satisfied) shall be converted into, and shall be canceled in exchange for, the right to receive 0.3471 shares of Parent Common Stock (the "Consideration"). The terms and conditions of the Transaction are more fully set forth in the Agreement.

        Capitalized terms used herein without definition have the respective meanings ascribed to them in the Agreement.

        You have requested our opinion as to the fairness, from a financial point of view, to Parent of the Consideration to be paid to the holders of the Company Common Stock in the proposed Transaction.

        In connection with preparing our opinion, we have reviewed, among other things:

        In arriving at our opinion, we have, with your consent, assumed and relied upon the accuracy and completeness of all information that was publicly available or supplied or otherwise made available to, discussed with or reviewed by or for us. We have not independently verified (nor have we assumed responsibility for independently verifying) such information or its accuracy or completeness. We have not undertaken or been provided with any independent evaluation or appraisal of any of the assets or liabilities (contingent or otherwise) of the Company or Parent, and we did not make an independent appraisal or analysis of the Company or Parent with respect to the Transaction. In addition, we have not assumed any obligation to conduct, nor have we conducted, any physical inspection of the properties or facilities of the Company or Parent, and have not been provided with any reports of such physical inspections. We have assumed that there has been no material change in the Company's or Parent's business, assets, financial condition, results of operations, cash flows or prospects since the date of the most recent financial statements provided to us, and that neither the Company nor Parent is party to any material pending transaction, including without limitation any financing, recapitalization, acquisition or merger, divestiture or spin-off, other than the Transaction.

        With respect to the financial forecasts and other analyses (including information relating to certain pro forma financial effects of, and strategic implications and operational benefits anticipated to result from, the Transaction) provided to or otherwise reviewed by or for or discussed with us, we have been advised by management of the Parent, and have assumed with your consent, that such forecasts and other analyses were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of management of Parent as to the future financial performance of the Company and Parent and the other matters covered thereby, and that the financial results (including the potential strategic implications and operational benefits anticipated to result from the Transaction) reflected in such forecasts and analyses will be realized in the amounts and at the times projected. We assume no responsibility for and express no opinion as to these forecasts and analyses or the assumptions on which they were based. We have relied on the assurances of management of Parent that they are not aware of any facts or circumstances that would make any of such information, forecasts or analyses inaccurate or misleading.

        We are not experts in the evaluation of loan and lease portfolios, classified loans or other real estate owned or in assessing the adequacy of the allowance for loan losses with respect thereto, and we did not make an independent evaluation or appraisal thereof, or of any other specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of the Company or Parent or any of their respective subsidiaries. We have not reviewed any individual loan or credit files relating to the Company or Parent. We have assumed, with your consent, that the respective allowances for loan and lease losses for both the Company and Parent are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity. We did not make an independent evaluation of the

quality of the Company's or Parent's deposit base, nor have we independently evaluated potential deposit concentrations or the deposit composition of the Company or Parent. We did not make an independent evaluation of the quality of the Company's or Parent's investment securities portfolio, nor have we independently evaluated potential concentrations in the investment securities portfolio of the Company or Parent.

        We have assumed that all of the representations and warranties contained in the Agreement and all related agreements are true and correct in all respects material to our analysis, and that the Transaction will be consummated in accordance with the terms of the Agreement, without waiver, modification or amendment of any term, condition or covenant thereof the effect of which would be in any respect material to our analysis. We also have assumed that all material governmental, regulatory or other consents, approvals, and waivers necessary for the consummation of the Transaction will be obtained without any material adverse effect on the Company or Parent or the contemplated benefits of the Transaction. Further, we have assumed that the executed Agreement will not differ in any material respect from the draft Agreement, dated December 9, 2016, reviewed by us.

        We have assumed in all respects material to our analysis that the Company will remain as a going concern for all periods relevant to our analysis. We express no opinion regarding the liquidation value of the Company or any other entity.

        Our opinion is limited to the fairness, from a financial point of view, to Parent of the Consideration to be paid to the holders of the Company Common Stock in the proposed Transaction. We do not express any view on, and our opinion does not address, any other term or aspect of the Agreement or Transaction (including, without limitation, the form or structure of the Transaction) or any term or aspect of any other agreement or instrument contemplated by the Agreement or entered into in connection with the Transaction, or as to the underlying decision by Parent to engage in the Transaction. Furthermore, we express no opinion with respect to the amount or nature of any compensation to any officers, directors or employees of the Company, or any class of such persons, relative to the Consideration to be paid to the holders of the Company Common Stock in the Transaction, or with respect to the fairness of any such compensation to Parent.

        We express no view as to, and our opinion does not address, the relative merits of the Transaction as compared to any alternative business transactions or strategies, or whether such alternative transactions or strategies could be achieved or are available. In addition, our opinion does not address any legal, regulatory, tax or accounting matters, as to which we understand that Parent obtained such advice as it deemed necessary from qualified professionals. We do not express any opinion as to the value of any asset of the Company whether at current market prices or in the future, or as to the price at which the Company or its assets could be acquired in the future. We also express no opinion as to the price at which the Company Common Stock or the common stock of Parent will trade following announcement of the Transaction or at any future time.

        We have not evaluated the solvency or fair value of the Company or Parent under any state, federal or other laws relating to bankruptcy, insolvency or similar matters. This opinion is not a solvency opinion and does not in any way address the solvency or financial condition of the Company or Parent. We are not expressing any opinion as to the impact of the Transaction on the solvency or viability of the Company or Parent or the ability of the Company or Parent to pay their respective obligations when they come due.

        We have acted as Parent's financial advisor in connection with the Transaction and will receive a fee for our services, a portion of which is payable upon the rendering of this opinion and a significant portion of which is contingent upon consummation of the Transaction. In addition, Parent has agreed to reimburse our reasonable expenses and indemnify us against certain liabilities arising out of our engagement.

Table of Contents

        During the two years preceding the date of this letter, we have provided investment banking and other financial services to Parent for which we have received customary compensation. Such services during such period have included acting as the Parent's financial advisor on the acquisitions of Security California Bancorp in 2016 and Independence Bank in 2015.

        In the ordinary course of our business, D.A. Davidson & Co. and its affiliates may actively trade or hold securities of the Company or Parent for our own accounts or for the accounts of our customers and, accordingly, may at any time hold long or short positions in such securities. We may seek to provide investment banking or other financial services to the Company or Parent in the future for which we would expect to receive compensation.

        This fairness opinion was reviewed and approved by a D.A. Davidson & Co. Fairness Opinion Committee.

        It is understood that this letter is for the information of the Board of Directors of Parent in connection with and for the purposes of its consideration of the Transaction. This opinion is not intended to be and does not constitute a recommendation as to how the shareholders of Parent should vote or act with respect to the Transaction or any matter relating thereto.

        This opinion is for the information of the Board of Directors of Parent and shall not be disclosed, referred to, published or otherwise used (in whole or in part), nor shall any public references to us be made, without our prior written consent, except that a copy of this opinion may be included in its entirety in any regulatory filing that Parent is required to make in connection with the Transaction if such inclusion is required by applicable law.

        Our opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof may affect this opinion and the assumptions used in preparing it, and we do not assume any obligation to update, revise or reaffirm this opinion.

        Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Consideration to be paid to the holders of the Company Common Stock in the Transaction is fair, from a financial point of view, to Parent.

Very truly yours,

APPENDIX C

December 11, 2016

Board of Directors
Heritage Oaks Bancorp
1222 Vine Street
Paso Robles, CA 93446

Ladies and Gentlemen:

        Heritage Oaks Bancorp (the "HEOP") and Pacific Premier Bancorp, Inc. ("PPBI") are proposing to enter into an Agreement and Plan of Reorganization (the "Agreement") pursuant to which HEOP will merge with and into PPBI, with PPBI being the surviving corporation (the "Merger"). Pursuant to the terms of the Agreement, at the Effective Date, each share of common stock, no par value, of HEOP ("HEOP Common Stock") issued and outstanding immediately prior to the Effective Date, except for certain shares of HEOP Common Stock as specified in the Agreement, will be converted into the right to receive 0.3471 shares (the "Exchange Ratio") of common stock, par value $0.01 per share, of PPBI ("PPBI Common Stock"). Capitalized terms used herein without definition have the meanings assigned to them in the Agreement. The terms and conditions of the Merger are more fully set forth in the Agreement. You have requested our opinion as to the fairness, from a financial point of view, of the Exchange Ratio to the holders of HEOP Common Stock.

        Sandler O'Neill & Partners, L.P. ("Sandler O'Neill", "we" or "our"), as part of its investment banking business, is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions. In connection with this opinion, we have reviewed and considered, among other things: (i) a draft of the Agreement, dated December 7, 2016; (ii) certain publicly available financial statements and other historical financial information of HEOP that we deemed relevant; (iii) certain publicly available financial statements and other historical financial information of PPBI that we deemed relevant; (iv) publicly available consensus mean analyst estimates for HEOP for the years ending December 31, 2016, December 31, 2017 and December 31, 2018, as well as estimated long-term annual earnings and asset growth rates for HEOP for the years thereafter, as provided by the senior management of HEOP; (v) publicly available consensus mean analyst estimates for PPBI for the years ending December 31, 2016, December 31, 2017 and December 31, 2018, as well as estimated long-term annual earnings and asset growth rates for the years thereafter, as provided by the senior management of PPBI; (vi) the pro forma financial impact of the Merger on PPBI based on certain assumptions relating to purchase accounting adjustments, cost savings and transaction expenses, as provided by the senior management of PPBI; (vii) the relative contribution of assets, liabilities, equity and earnings of HEOP and PPBI to the combined entity; (viii) the publicly reported historical price and trading activity for HEOP Common Stock and PPBI Common Stock, including a comparison of certain stock market information for HEOP Common Stock and PPBI Common Stock and certain stock indices as well as publicly available information for certain other similar companies, the securities of which are publicly traded; (ix) a comparison of certain financial information for HEOP and PPBI with similar institutions for which information is publicly available; (x) the financial terms of certain recent business combinations in the bank and thrift industry on a regional and nationwide basis, to the extent publicly available; (xi) the current market environment generally and the banking environment in particular; and (xii) such other information, financial studies, analyses and investigations and financial, economic and market criteria as we considered relevant. We also discussed with certain members of the senior management of HEOP the business, financial condition, results of operations and prospects of HEOP and held similar discussions with certain members of the senior management of PPBI regarding the business, financial condition, results of operations and prospects of PPBI.

Table of Contents

        In performing our review, we have relied upon the accuracy and completeness of all of the financial and other information that was available to and reviewed by us from public sources, that was provided to us by HEOP or PPBI or their respective representatives or that was otherwise reviewed by us, and we have assumed such accuracy and completeness for purposes of rendering this opinion without any independent verification or investigation. We have relied on the assurances of the respective managements of HEOP and PPBI that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. We have not been asked to and have not undertaken an independent verification of any of such information and we do not assume any responsibility or liability for the accuracy or completeness thereof. We did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of HEOP or PPBI or any of their respective subsidiaries, nor have we been furnished with any such evaluations or appraisals. We render no opinion or evaluation on the collectability of any assets or the future performance of any loans of HEOP or PPBI. We did not make an independent evaluation of the adequacy of the allowance for loan losses of HEOP or PPBI, or of the combined entity after the Merger, and we have not reviewed any individual credit files relating to HEOP or PPBI. We have assumed, with your consent, that the respective allowances for loan losses for both HEOP and PPBI are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity.

        In preparing its analyses, Sandler O'Neill used publicly available consensus mean analyst estimates for HEOP for the years ending December 31, 2016, December 31, 2017 and December 31, 2018, as well as estimated long-term annual earnings and asset growth rates for HEOP for the years thereafter, as provided by the senior management of HEOP. In addition, Sandler O'Neill used publicly available consensus mean analyst estimates for PPBI for the years ending December 31, 2016, December 31, 2017 and December 31, 2018, as well as estimated long-term annual earnings and asset growth rates for the years thereafter, as provided by the senior management of PPBI. Sandler O'Neill also received and used in its pro forma analyses certain assumptions relating to purchase accounting adjustments, cost savings and transaction expenses, as provided by the senior management of PPBI. With respect to the foregoing information, the respective senior managements of HEOP and PPBI confirmed to us that such information reflected (or, in the case of the publicly available consensus mean analyst earnings per share estimates referred to above, were consistent with) the best currently available estimates and judgments of those respective senior managements as to the future financial performance of HEOP and PPBI, respectively, and the other matters covered thereby, and we assumed that the future financial performance reflected in such information would be achieved. We express no opinion as to such information, or the assumptions on which such information is based. We have also assumed that there has been no material change in the respective assets, financial condition, results of operations, business or prospects of HEOP or PPBI since the date of the most recent financial statements made available to us. We have assumed in all respects material to our analysis that HEOP and PPBI will remain as going concerns for all periods relevant to our analysis.

        We have also assumed, with your consent, that (i) each of the parties to the Agreement will comply in all material respects with all material terms and conditions of the Agreement and all related agreements, that all of the representations and warranties contained in such agreements are true and correct in all material respects, that each of the parties to such agreements will perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements are not and will not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on HEOP, PPBI or the Merger or any related transaction, (iii) the Merger and any related transactions will be consummated in accordance with the terms of the Agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements, and (iv) the Merger will qualify as a

tax-free reorganization for federal income tax purposes. Finally, with your consent, we have relied upon the advice that HEOP has received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Merger and the other transactions contemplated by the Agreement. We express no opinion as to any such matters.

        Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof could materially affect this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or otherwise comment upon events occurring after the date hereof. We express no opinion as to the trading values of HEOP Common Stock or PPBI Common Stock at any time or what the value of PPBI Common Stock will be once it is actually received by the holders of HEOP Common Stock.

        We have acted as HEOP's financial advisor in connection with the Merger and will receive a fee for our services, a substantial portion of which is contingent upon consummation of the Merger. We will also receive a fee for rendering this opinion, which opinion fee will be credited in full towards the portion of the transaction fee which will become payable to Sandler O'Neill on the day of closing of the Merger. HEOP has also agreed to indemnify us against certain claims and liabilities arising out of our engagement and to reimburse us for certain of our out-of-pocket expenses incurred in connection with our engagement. We have not provided any other investment banking services to HEOP in the two years preceding the date of this opinion nor have we provided any investment banking services to PPBI in the two years preceding the date of this opinion. In the ordinary course of our business as a broker-dealer, we may purchase securities from and sell securities to HEOP, PPBI and their respective affiliates. We may also actively trade the equity and debt securities of HEOP, PPBI and their respective affiliates for our own account and for the accounts of our customers.

        Our opinion is directed to the Board of Directors of HEOP in connection with its consideration of the Agreement and the Merger and does not constitute a recommendation to any shareholder of HEOP as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the Agreement and the Merger. Our opinion is directed only to the fairness, from a financial point of view, of the Exchange Ratio to the holders of HEOP Common Stock and does not address the underlying business decision of HEOP to engage in the Merger, the form or structure of the Merger or any other transactions contemplated in the Agreement, the relative merits of the Merger as compared to any other alternative transactions or business strategies that might exist for HEOP or the effect of any other transaction in which HEOP might engage. We also do not express any opinion as to the fairness of the amount or nature of the compensation to be received in the Merger by any officer, director or employee of HEOP or PPBI, or any class of such persons, if any, relative to the compensation to be received in the Merger by any other shareholder. This opinion has been approved by Sandler O'Neill's fairness opinion committee. This opinion shall not be reproduced without Sandler O'Neill's prior written consent; provided, however, Sandler O'Neill will provide its consent for the opinion to be included in regulatory filings to be completed in connection with the Merger.

        Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio is fair to holders of HEOP Common Stock from a financial point of view.

    Very truly yours,

 

 

/s/ Sandler O'Neill & Partners, L.P.

PART II
INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.    Indemnification of Directors and Officers.

        The following is a summary of relevant provisions of our amended and restated certificate of incorporation, and certain provisions of the General Corporation Law of the State of Delaware, or the DGCL. We urge you to read the full text of these documents, forms of which have been filed with the U.S. Securities and Exchange Commission, as well as the referenced provisions of the DGCL because they are the legal documents and provisions that will govern matters of indemnification with respect to our directors and officers.

        We are incorporated under the laws of the state of Delaware. Section 145 of the DGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. A similar standard is applicable in the case of derivative actions, except that indemnification only extends to expenses (including attorneys' fees) incurred in connection with the defense or settlement of such action, and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation.

        The DGCL provides that any indemnification must be made by us only as authorized in the specific case upon a determination that indemnification is proper in the circumstances because the person has met the applicable standard of conduct. Such determination must be made, with respect to person who is a director or officer at the time of such determination, (i) by a majority of our directors who are not parties to the action, suit or proceeding, even though less than a quorum, or (ii) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (iv) by our stockholders.

        The statute provides that it is not exclusive of other indemnification that may be granted by a corporation's bylaws, disinterested director vote, stockholder vote, agreement or otherwise.

        Our amended and restated certificate of incorporation provides for the indemnification of directors, officers and certain of our authorized representatives to the fullest extent permitted by the DGCL, except that indemnification in an action, suit or proceeding initiated by a director, officer or our authorized representative is permitted only if our board of directors authorized the initiation of that action, suit or proceeding. In addition, as permitted by the DGCL, our amended and restated certificate of incorporation provides that our directors shall have no personal liability to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except (i) for any breach of the director's duty of loyalty to us or our stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or knowing violation of the law, (iii) the unlawful payment of dividends or unlawful stock purchase or redemption, or (iv) for any transaction in which the director derived improper personal benefit.
