FILED PURSUANT TO RULE 424(b)(3)
REG. STATEMENT NO. 333-187688

        SAN DIEGO TRUST BANK
2550 Fifth Avenue
Suite 1010
San Diego, California 92103

PROPOSED MERGER—YOUR VOTE IS VERY IMPORTANT

Dear San Diego Trust Bank shareholders:

        You are cordially invited to attend a special meeting of shareholders of San Diego Trust Bank, or SDTB, to be held at 5:30 p.m., Pacific Time, on Friday, June 21, 2013 at SDTB's main branch located at 2550 5th Avenue #120, San Diego, California 92103. At the special meeting, you will be asked to consider and vote upon a proposal to approve an agreement and plan of reorganization, which is referred to in this document as the merger agreement, pursuant to which SDTB will be merged with and into Pacific Premier Bank, a wholly owned subsidiary of Pacific Premier Bancorp, Inc., or Pacific Premier.

        If the merger agreement is approved and the transaction is subsequently completed, each outstanding share of SDTB common stock will be cancelled and converted into the right to receive $13.41 in cash, without interest, or 1.114 shares of Pacific Premier common stock. Both the stock portion and the cash portion of the merger consideration will be subject to possible adjustment prior to the closing of the merger.

        SDTB shareholders will have the opportunity to elect to receive all cash, all stock, or a combination of cash and stock for all shares of SDTB common stock held by them, subject to allocation procedures which are intended to ensure that 50% of the aggregate value of the merger consideration is paid in the form of shares of Pacific Premier common stock and 50% of the aggregate merger consideration is paid in cash. Cash will be paid in lieu of any fractional share interest.

        The stock portion of the merger consideration is subject to possible downward or upward adjustment based on the average closing stock price of Pacific Premier common stock for the 10 trading day period ending on the fifth business day prior to the effective time of the merger, or the PPBI Average Share Price. The per share stock consideration of 1.114 shares of Pacific Premier common stock is subject to (i) downward adjustment if the PPBI Average Share Price is greater than $13.240 and (ii) upward adjustment if the PPBI Average Share Price is less than $10.832. If the PPBI Average Share Price is equal to or greater than $10.832 but less than or equal to $13.240, then no adjustment will be made to the per share stock consideration. In no event will the upward adjustment to the per share stock consideration increase beyond a number of shares of Pacific Premier common stock that would result in Pacific Premier issuing to SDTB shareholders in the aggregate more than 19.9% of its outstanding shares of Pacific Premier common stock at the closing of the merger. Upon completion of the merger, and based on 2,151,395 shares of SDTB common stock outstanding as of May 9, 2013 and assuming there is no adjustment to the per share stock consideration, SDTB shareholders are expected to receive 1,198,327 shares of Pacific Premier common stock.

        The implied value of the per share stock consideration to be paid to SDTB shareholders is based on the exchange ratio of 1.114 shares of Pacific Premier common stock for one share of SDTB common stock. The implied value on May 9, 2013 was $13.95, which amount was based on the closing price per share of Pacific Premier common stock on that date. The value of the stock portion of the merger consideration will fluctuate both based on the market price of Pacific Premier common stock and the fact that the exchange ratio may be subject to upward or downward adjustment, as discussed in the paragraph above and in more detail in the accompanying proxy statement/prospectus. Consequently, the value of the stock portion of the merger consideration will not be known at the time you vote on the merger agreement. Pacific Premier's common stock is listed on the Nasdaq Global Market under the symbol "PPBI." You should obtain current market quotations for the Pacific Premier common stock.

        The cash portion of the merger consideration is subject to downward adjustment if SDTB's aggregate transaction-related expenses exceed $3.0 million, on an after-tax equivalent basis, with any


Table of Contents

excess reducing the per share cash consideration by the quotient of (i) such excess amount divided by (ii) the total number of shares of issued and outstanding SDTB common stock. However, the cash portion of the merger consideration is not subject to an upward adjustment if SDTB's aggregate transaction-related expenses are less than $3.0 million, on an after-tax equivalent basis. Because the cash portion of the merger consideration is subject to possible downward adjustment, the amount of cash consideration to be received will not be known at the time you vote on the merger agreement. Although no assurances can be made as to the final amount of SDTB's transaction-related expenses as of the closing date of the merger, SDTB does not anticipate that its transaction-related expenses, on an after-tax basis, will exceed $3.0 million based on currently available information.

        Based on our reasons for the transaction described in the accompanying document, including the fairness opinion issued by our financial advisor, Keefe, Bruyette & Woods, Inc., our board of directors believes that the transaction is fair to you and in your best interests. Accordingly, our board of directors unanimously recommends that you vote "FOR" approval of the merger agreement.

        The accompanying proxy statement/prospectus gives you detailed information about the special meeting, the transaction and related matters. In addition to being a proxy statement of SDTB, this document is the prospectus of Pacific Premier for the shares of its common stock that will be issued in connection with the transaction. We advise you to read this entire document carefully, including the considerations discussed under "Risk Factors" beginning on page 31, and the appendices to the accompanying proxy statement/prospectus, which include the merger agreement.

        Your vote is very important. The transaction cannot be completed unless the holders of a majority of the outstanding shares of SDTB common stock vote in favor of approval of the merger agreement at the special meeting. Whether or not you plan to attend the 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 we look forward to seeing you at the special meeting.

  Sincerely,

QUESTIONS AND ANSWERS
ABOUT THE MERGER AND THE SPECIAL MEETING

        The following are some questions that you may have regarding the merger and the special meeting, and brief answers to those questions. Pacific Premier and SDTB advise you to read carefully the remainder of this proxy statement/prospectus because the information in this section does not provide all of the information that might be important to you with respect to the merger and the special meeting. Additional important information is also contained in the documents incorporated by reference into this proxy statement/prospectus. See "Where You Can Find More Information" beginning on page 136.

Q:
What am I being asked to vote on?

A:
You are being asked to vote to approve the merger agreement. As a result of the merger, SDTB will cease to exist and SDTB shareholders will exchange their shares of the common stock of SDTB, or SDTB common stock, for the merger consideration, which is comprised of (i) 1.114 shares of common stock of Pacific Premier, or Pacific Premier common stock, or (ii) $13.41 in cash, without interest. Both the stock portion and the cash portion of the merger consideration are subject to adjustment prior to the consummation of the merger, as further described in "The Merger—The Merger Consideration" beginning on page 57.
Q.
Can I elect the type of merger consideration that I will receive in the merger?

A.
Yes. Subject to the allocation procedures described in this proxy statement/prospectus which are intended to ensure that 50% of the aggregate value of the merger consideration is paid in the form of shares of Pacific Premier common stock and 50% is paid in cash, you may elect to receive one of the following options in exchange for your SDTB common stock:

all cash;

all Pacific Premier common stock; or

a portion in cash and a portion in Pacific Premier common stock in amounts you select.
Q.
How do I elect to receive cash, shares of Pacific Premier common stock or a combination of cash and stock for my shares of SDTB common stock?

A.
A form for making an election will be sent to you no later than the date that this proxy statement/prospectus is mailed to holders of record of SDTB common stock. Each SDTB shareholder should complete the election form indicating the form of merger consideration they would like to receive, whether all cash, all Pacific Premier common stock, or a combination of cash and stock in amounts determined by each SDTB shareholder, subject to the allocation procedures. For additional information about the allocation procedures, see "The Merger—The Merger Consideration—Allocation Procedures" beginning on page 61.

1


Table of Contents

Q:
Will I receive the form of consideration I elect to receive?

A:
Not necessarily. The allocation procedures described in this proxy statement/prospectus beginning on page 61 and set forth in the merger agreement are intended to ensure that 50% of the aggregate merger consideration paid by Pacific Premier to holders of SDTB common stock will be Pacific Premier common stock, and 50% of the aggregate consideration will be paid in cash. While SDTB shareholders will have the opportunity to elect all cash, all Pacific Premier common stock or a portion in cash and a portion in Pacific Premier common stock, there is no assurance that you will receive the form of consideration you elect with respect to the SDTB common stock you hold. If there is an oversubscription for either cash or Pacific Premier common stock, then Pacific Premier will cause the exchange agent to allocate the aggregate consideration to be received by SDTB shareholders according to the procedures set forth in this document such that 50% of the aggregate consideration is paid in cash and 50% is paid in Pacific Premier common stock.

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

A:
Yes. The Pacific Premier common stock issued in the merger will be listed on the Nasdaq Global 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 SDTB common stock. If you do not vote, it will have the same effect as a vote against the merger agreement. Holders of 518,866 shares of SDTB common stock, representing approximately 24.1% of the outstanding shares of SDTB common stock, have signed shareholder agreements with Pacific Premier agreeing to vote in favor of the merger agreement.

Q:
What does the SDTB board of directors recommend?

A:
The SDTB board of directors unanimously recommends that you vote "FOR" approval of the merger agreement and "FOR" approval of the proposal to adjourn the special meeting, if necessary, to solicit additional proxies in favor of adoption of the merger agreement.

Q:
Will I have dissenters' rights in connection with the merger?

A:
Yes. Holders of SDTB common stock have the right to dissent from the merger and assert dissenters' rights, provided the requirements of California law governing dissenters' rights are followed. Any SDTB shareholder who desires to exercise dissenters' rights must not have voted his, her or its shares of SDTB common stock "FOR" approval of the merger agreement. To preserve dissenters' rights, an SDTB shareholder must make a written demand for the purchase of their shares of SDTB common stock and payment to them of the fair market value of their shares of SDTB common stock within 30 days after the date on which notice of SDTB shareholder approval of the merger agreement is mailed to SDTB shareholders that did not vote "FOR" approval of the merger agreement. Simply failing to vote for, or voting against, the merger agreement does not constitute a proper written demand under the California General Corporation Law, or CGCL.

Table of Contents

Q:
Are there any risks I should consider in deciding whether I vote for the merger agreement?

A:
Yes. Set forth under the heading of "Risk Factors," beginning on page 31, are a number of risk factors that you should consider carefully.

Q:
When do you expect to complete the merger?

A:
The parties expect to complete the merger late in the second quarter of 2013 or in the third quarter of 2013. However, there is no assurance when or if the merger will occur. Prior to the consummation of the merger, SDTB shareholders must approve the merger agreement at the special meeting and other conditions to the consummation of the merger must be satisfied. Pacific Premier and SDTB have received approval from each of the applicable banking regulators for the merger.

Q:
When and where is the SDTB special shareholders meeting?

A:
The special meeting will be held at 5:30 p.m., Pacific Time, on Friday, June 21, 2013 at SDTB's main branch located at 2550 5th Avenue #120, San Diego, California 92103.

Q:
Who is entitled to vote at the special meeting?

A:
The holders of record of SDTB common stock at the close of business on May 9, 2013, which is the date SDTB's board of directors has fixed as the record date for the special meeting, are entitled to vote at the special meeting.

Q:
What do I need to do now?

A:
After you have carefully read this proxy statement/prospectus, indicate on your proxy card how you want your shares of SDTB common stock to be voted. Then sign, date and mail your proxy card in the enclosed postage-paid return envelope as soon as possible. Alternatively, you may vote by following the Internet and telephone voting instructions indicated on the proxy card. This will enable your shares of SDTB common stock to be represented and voted at the special meeting.

Q:
If my shares are held in street name by my broker, will my broker automatically vote my shares for me?

A:
No. Your bank, broker or other nominee will not be able to vote shares held by it in street name on your behalf without instructions from you. You should instruct your bank, broker or other nominee to vote your shares by following the directions your bank, broker or other nominee provides to you.

Q:
What if I abstain from voting or fail to instruct my broker?

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

Table of Contents

Q.
What if I fail to instruct my broker to complete the election form?

A.
If an SDTB shareholder fails to instruct his or her broker or other nominee on which election to make, such SDTB shareholder will be treated as if he or she did not make an election with respect to the merger consideration to be received by such SDTB shareholder in exchange for his or her shares of SDTB common stock. Such shares will be treated as no-election shares and will be subject to the allocation procedures described in this proxy statement/prospectus. For additional information about the allocation procedures, see "The Merger—The Merger Consideration—Allocation Procedures" beginning on page 61.

Q:
Can I attend the special meeting and vote my shares in person?

A:
Yes. All SDTB shareholders are invited to attend the special meeting. Shareholders of record can vote in person at the special meeting. If your shares are held in street name, then you are not the shareholder of record and you must bring a legal proxy from your broker, bank or other nominee confirming that you are the beneficial owner of the shares in order to vote in person at the special meeting.

Q:
Can I change my vote?

A:
Yes. Regardless of the method used to cast a vote, if a SDTB shareholder is a holder of record, he or she may change his or her vote by:

delivering to SDTB prior to the special meeting a written notice of revocation addressed to Michael E. Perry, Chairman, President and Chief Executive Officer, San Diego Trust Bank, 2550 Fifth Avenue, Suite 1010, San Diego, California 92103;

completing, signing and returning a new proxy card with a later date before the date of the special meeting, and any earlier proxy will be revoked automatically; or

attending the special meeting and voting in person, and any earlier proxy will be revoked. However, simply attending the special meeting without voting will not revoke his or her proxy.
Q:
Will SDTB be required to submit the merger agreement to its shareholders even if the SDTB board of directors has withdrawn, modified or qualified its recommendation?

A:
Yes. Unless the merger agreement is terminated before the special meeting, SDTB is required to submit the merger agreement to its shareholders even if the SDTB board of directors has withdrawn, modified or qualified its recommendation, consistent with the terms of the merger agreement.

Table of Contents

Q:
What is the procedure for sending in my stock certificates?

A:
SDTB shareholders will be receiving a letter of transmittal with their election form that will provide instructions for SDTB shareholders to surrender their SDTB common stock certificates in exchange for the merger consideration. The letter of transmittal will be sent to you at approximately the same time that you will be sent this proxy statement/prospectus. SDTB shareholders should follow the instructions in the letter of transmittal for how to deliver their SDTB common stock certificates in exchange for the merger consideration. The SDTB common stock certificates should not be sent with your proxy card. Instead, use the separate envelope specifically provided with the letter of transmittal for returning the SDTB stock certificates and the election form.

Q:
Who should I call with questions?

A:
If you have questions about the merger or the process for voting or if you need additional copies of this document or a replacement proxy card, please contact Michael E. Perry, SDTB's Chairman, President and Chief Executive Officer, at (619) 525-1727, or Toby Reschan, SDTB's Senior Executive Vice President and Chief Operating Officer, at (619) 525-1728.

As of December 31, 2012, Pacific Premier had, on a consolidated basis, total assets of $1.2 billion, total stockholders' equity of $134.5 million and total deposits of $904.8 million. At December 31, 2012, Pacific Premier had real estate loans and business loans collateralized by real estate totaling 67.9% of its gross loan portfolio. Beginning with the 2013 fiscal year, Pacific Premier's filing status with the Commission transitioned from a "smaller reporting company" to an "accelerated filer," as those terms are defined under Commission rules. Under the Commission's rules, Pacific Premier is permitted to continue to provide the scaled disclosure required of a "smaller reporting company" in its filings with the Commission until its quarterly report on Form 10-Q for the quarter ended March 31, 2013.

        Based on information contained in Schedule 13Ds, Schedule 13Gs and Schedule 13Fs filed with the Commission, there are two shareholders (each of which is an institutional shareholder) who collectively beneficially own an aggregate of approximately 14.81% of Pacific Premier's outstanding common stock. These two shareholders, together with the shares of Pacific Premier common stock beneficially owned by Steven Gardner, Pacific Premier's president and chief executive officer, beneficially own an aggregate of approximately 15.63% of Pacific Premier's outstanding common stock. Pacific Premier is not aware of any agreements, arrangements or understandings between such shareholders with respect to the voting or disposition of any shares of Pacific Premier common stock.

        Other than as publicly disclosed in their respective Schedule 13Ds, Schedule 13Gs or Schedule 13Fs filed with the Commission, Pacific Premier is not aware of any increase or decrease in the beneficial ownership of these seven shareholders, including as a result of the shares of common stock sold in Pacific Premier's recently completed public offering. To the extent that any of these seven shareholders purchased additional shares of Pacific Premier common stock in the offering or purchased or sold shares of Pacific Premier common stock in the open market, through privately negotiated

transactions or otherwise, their collective beneficial ownership of shares of Pacific Premier's common stock could have changed from the percentages provided above.

        Pacific Premier's principal executive offices are located at 17901 Von Karman Ave., Suite 1200, Irvine, California 92614 and its telephone number is (949) 864-8000.

        On March 15, 2013, Pacific Premier completed its acquisition of FAB, which operated from its headquarters in Dallas, Texas. In connection with the consummation of the FAB acquisition, Pacific Premier issued 1,279,217 shares of its common stock and paid approximately $37.2 million in cash as consideration to the holders of FAB common stock in exchange for their shares.

        Prior to the acquisition, FAB was a commercial bank that exclusively focused on providing deposit and other services to HOAs and HOA management companies nationwide. FAB did not accept retail or consumer deposits or provide other lending or other more traditional banking services to consumers or other type of commercial customers. The FAB business of servicing HOAs and HOA management companies will be joined with the Bank's existing Premier Property Banking Unit, which focuses exclusively on generating business banking relationships and servicing the specialized banking needs of property management companies, HOA management companies and their respective clients. The provision of financial services to HOAs and HOA management companies is highly competitive. The Bank's Premier Property Banking Unit will be competing nationwide with a number of other financial institutions that provide banking services for property management, HOA management companies and HOAs.

        At December 31, 2012, FAB had total assets of approximately $375.7 million, total stockholders' equity of approximately $46.2 million and total deposits of approximately $319.8 million. As of December 31, 2012, Pacific Premier and FAB would have, on a pro forma consolidated basis, total assets of approximately $1.5 billion, total stockholders' equity of $147.4 million and total deposits of $1.2 billion. See "Unaudited Pro Forma Combined Consolidated Financial Data" beginning on page 117.

The Merger (Page 42)

        The merger agreement is attached to this proxy statement/prospectus as Appendix A, which is incorporated by reference into this 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, SDTB will be acquired by Pacific Premier whereby SDTB will merge with and into the Bank, with the Bank as the surviving institution. The parties expect to complete the merger late in the second quarter of 2013 or in the third quarter of 2013.


SDTB's Reasons for Merger and Factors Considered by SDTB's Board of Directors (Page 47)

        Based on SDTB's reasons for the merger described herein, including the fairness opinion of Keefe Bruyette & Woods, Inc., or KBW, an independent investment banking firm, the SDTB board of directors believes that the merger is fair to SDTB shareholders and in their best interests, and

Table of Contents

unanimously recommends that SDTB shareholders vote "FOR" approval of the merger agreement. For a discussion of the circumstances surrounding the merger and the factors considered by SDTB's board of directors in approving the merger agreement, see "The Merger—SDTB's Reasons for the Merger" beginning on page 47.


Pacific Premier's Reasons for Merger (Page 49)

        As part of its business strategy, Pacific Premier evaluates opportunities to acquire bank holding companies, banks and other financial institutions. The acquisition of SDTB is consistent with this strategy and will result in the Bank expanding its operations into the new Southern California market of San Diego County. In addition to meeting one of its strategic objectives, Pacific Premier believes that the acquisition of SDTB will also (i) create new opportunities for the bank to provide its expansive products and services to the SDTB customers, (ii) improve and strengthen the Bank's deposit base with low cost core deposits and (iii) better position the Bank for long-term growth.


SDTB's Financial Advisor Believes that the Merger Consideration is Fair, From a Financial Point of View, to SDTB Shareholders (Page 49)

        KBW delivered its written opinion to SDTB's board of directors that, as of March 5, 2013, and based upon and subject to the factors and assumptions set forth in the opinion, the merger consideration to be received by the holders of the outstanding SDTB common stock pursuant to the merger agreement was fair from a financial point of view to such holders.

        The full text of the written opinion of KBW, dated March 5, 2013, which sets forth assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken in connection with the opinion, is attached as Appendix B to this proxy statement/prospectus. SDTB's shareholders should read the opinion in its entirety. KBW provided its opinion for the information and assistance of SDTB's board of directors in connection with its consideration of the transaction. KBW did not express any view on, and its opinion did not address, the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of SDTB, or any class of such persons in connection with the merger, whether relative to the consideration payable to the SDTB shareholders in connection with the merger or otherwise. The KBW opinion does not address the underlying business decision to proceed with the merger and is not a recommendation as to how any holder of SDTB common stock should vote or make any election with respect to the merger agreement or any related matter.

        SDTB began working with KBW in April of 2012 for the primary purpose of identifying a potential strategic merger partner, which led to contacting Pacific Premier in September, 2012 and eventually entering into the merger agreement. SDTB engaged KBW as its exclusive financial advisor in November of 2012 and pursuant to the terms of KBW's engagement as financial advisor and other advisory services, SDTB agreed to pay KBW 1% of the aggregate consideration paid in an acquisition of SDTB plus $100,000 for a fairness opinion. As of the date of this proxy statement/prospectus, SDTB has paid $100,000 in fees to KBW in connection with the merger. SDTB estimates that the remaining fee payable to KBW in connection with the merger will be approximately $306,080.


SDTB Shareholders Will Receive Cash or Shares of Pacific Premier Common Stock for Each Share of SDTB Common Stock Exchanged in the Merger (Page 57)

        At the effective time of the merger, each outstanding share of SDTB common stock (subject to certain exceptions) will, by virtue of the merger and without any action on the part of a SDTB shareholder, be converted into the right to receive, subject to possible adjustment as discussed below, (i) $13.41 in cash, without interest, subject to downward adjustment as described below, or the per share cash consideration, or (ii) 1.114 shares of Pacific Premier common stock, subject to upward or downward adjustment based on changes in the stock price of Pacific Premier common stock as described below, or the per share stock consideration. Cash will be paid in lieu of any fractional share interest.

Table of Contents

        SDTB shareholders will have the opportunity to elect the form of consideration to be received for all shares of SDTB common stock held by them, whether all stock, all cash or a combination of stock and cash, subject to the allocation procedures provided for in the merger agreement, which are intended to ensure that 50% of the aggregate value of the merger consideration is paid in the form of shares of Pacific Premier common stock, and 50% of the aggregate merger consideration is paid in cash.

        Per Share Cash Consideration and Possible Adjustment.    The cash portion of the merger consideration will be subject to downward adjustment if SDTB's aggregate transaction-related expenses exceed $3.0 million, on an after-tax equivalent basis, with any excess amount reducing the per share cash consideration by the quotient of (i) such excess amount divided by (ii) the total number of shares of issued and outstanding SDTB common stock. Pursuant to the terms of the merger agreement, SDTB's transaction-related expenses consist of certain fixed amounts, such as SDTB's accounting and advisory fees and expenses associated with the accrual of benefits, change in control and other contractual payments and non-competition payments payable to SDTB's Chairman, Chief Executive Officer and President, Michael E. Perry, which are estimated to amount to $2.7 million in the aggregate on an after-tax basis, of which $2.5 million is in connection with payments to Mr. Perry, as well as certain amounts that are not fixed, such as SDTB's legal fees and premiums for extended directors and officers liability insurance to the extent premiums exceed 200% of current SDTB premiums. As of May 9, 2013, which is the latest practicable date before the filing of this proxy statement/prospectus, the aggregate amount of estimated fixed transaction-related expenses plus the variable transaction-related expenses actually incurred by SDTB, on an after-tax equivalent basis, totaled approximately $2.8 million. Although no assurances can be made as to the final amount of SDTB's transaction-related expenses as of the closing date of the merger, SDTB does not anticipate that its transaction-related expenses, on an after-tax basis, will exceed $3.0 million based on currently available information. The cash portion of the merger consideration is not subject to an upward adjustment if SDTB's aggregate transaction-related expenses are less than $3.0 million, on an after-tax equivalent basis. Because the cash portion of the merger consideration is subject to a downward adjustment, the amount of cash consideration to be received will not be known at the time SDTB shareholders elect the form of merger consideration they wish to receive or when SDTB shareholders vote on the merger agreement. To the extent that no downward adjustment to the per share cash consideration occurs and based on the allocation procedures which will provide for 50% of the 2,151,395 shares of SDTB common stock outstanding shall elect to receive the per share cash consideration, the cash portion of the merger consideration would be $14,425,103, or $13.41 for each share of SDTB common stock.

        Per Share Stock Consideration and Possible Adjustment.    The per share stock consideration of 1.114 shares of Pacific Premier common stock is subject to possible downward or upward adjustment based on the average closing stock price of Pacific Premier common stock for the 10 trading day period ending on the fifth business day prior to the effective time of the merger, or the PPBI Average Share Price. If the PPBI Average Share Price is greater than $13.240, then the per share stock consideration will be adjusted downward to equal (i) $14.751 divided by (ii) the PPBI Average Share Price, rounded to the nearest thousandth. If the PPBI Average Share Price is less than $10.832, then the per share stock consideration will be adjusted upward to equal (x) $12.069 divided by (y) the PPBI Average Share Price, rounded to the nearest thousandth. In no event shall the upward adjustment to the per share stock consideration increase beyond a number of shares of Pacific Premier common stock that would result in Pacific Premier issuing to SDTB shareholders in the aggregate more than 19.9% of its outstanding shares of Pacific Premier common stock at the closing of the merger. Assuming a closing date immediately prior to the date of filing of this proxy statement/prospectus, the PPBI Average Share Price would be calculated to be $12.215, and therefore no adjustment would occur to the per share stock consideration. To the extent that no adjustment to the per share stock consideration occurs and based on the allocation procedures, which provide that 50% of the 2,151,395 shares of SDTB common

stock outstanding shall receive the per share stock consideration, the stock portion of the merger consideration will result in 1,198,327 shares of Pacific Premier common stock being issued.

        Aggregate Merger Consideration.    The aggregate per share cash consideration together with the aggregate per share stock consideration is referred to as the merger consideration. Upon completion of the merger, approximately $29.4 million of merger consideration will be payable to the SDTB shareholders, which assumes (i) the per share cash consideration and the per share stock consideration are not adjusted, (ii) the implied value of the per share stock consideration is $13.95 (based on the closing price per share of Pacific Premier's common stock on May 9, 2013 multiplied by the exchange ratio of 1.114) and (iii) that there are 2,151,395 shares of SDTB common stock outstanding.

        Merger Consideration Example.    The following table illustrates what the exchange ratio, the related per share stock consideration, the per share cash consideration and the aggregate stock, cash and merger consideration value, would be depending upon changes to the PPBI Average Share Price, ranging from 20% above $12.036, which was the PPBI Average Share Price as of March 5, 2013, to 20% below $12.036. The following table assumes there are 2,151,395 shares of SDTB common stock outstanding as of the closing date, and that the per share cash consideration is $13.41. The table reflects that the aggregate merger consideration paid will consist of 50% cash and 50% shares of Pacific Premier common stock, and therefore, 1,075,698 shares of SDTB common stock will be exchanged for the per share stock consideration. As described below under "The Merger—The Merger Consideration—Allocation Procedures" beginning on page 61, regardless of whether an SDTB shareholder makes an all-cash election or an all-stock election, that SDTB shareholder may nevertheless receive a mix of cash and shares of Pacific Premier common stock as merger consideration. The table does not reflect the fact that cash will be paid instead of fractional shares.

The value of the stock portion of the merger consideration will (i) fluctuate based on the market price of Pacific Premier common stock and such value on the closing date of the merger and (ii) be subject to upward or downward adjustment if the PPBI Average Share Price is either less than $10.832 or greater than $13.240, and therefore, the value of the stock portion of the merger consideration will not be known at the time you vote on the merger agreement or elect the form of

merger consideration you would like to receive. Pacific Premier's common stock is listed on the Nasdaq Global Market under the symbol "PPBI." You should obtain current market quotations for the Pacific Premier common stock.

        Upon completion of the merger, and based on 2,151,395 shares of SDTB common stock outstanding as of the date of this proxy statement/prospectus and assuming there is no adjustment to the per share stock consideration, SDTB shareholders are expected to receive 1,198,327 shares of Pacific Premier common stock. Following the completion of the merger, and based on 15,437,531 shares of Pacific Premier common stock outstanding as of May 9, 2013, the former SDTB shareholders will own approximately 7.20% of the outstanding shares of Pacific Premier common stock and the current shareholders of Pacific Premier will own the remaining approximately 92.80% of the outstanding shares of Pacific Premier common stock.

        The examples above are illustrative only and are based on the assumptions indicated. The value of the merger consideration that an SDTB shareholder actually receives will be based on the actual PPBI Average Share Price calculated prior to completion of the merger. The actual PPBI Average Share Price may be outside the range of the amounts set forth above, and as a result, the actual value of the merger consideration per share of SDTB common stock may not be shown in the above table.

        Fractional Shares.    No fractional shares of Pacific Premier common stock will be issued, and in lieu thereof, each holder of SDTB 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 $13.41, which amount reflects per share cash consideration, rounded to the nearest whole cent.


What Will Happen to Outstanding SDTB Stock Options (Page 62)

        Pursuant to the terms of the merger agreement, each stock option to purchase shares of SDTB's common stock, referred to in this proxy statement/prospectus as an SDTB option, that is outstanding but not exercisable will be declared fully vested and exercisable for a period of three (3) months ending immediately before the anticipated closing date of the merger. Each SDTB option that remains outstanding as of the closing of the merger will be cancelled in accordance with the San Diego Trust Bank Second Amended and Restated 2003 Stock Plan, referred to in this proxy statement/prospectus as the SDTB Stock Option Plan, upon the closing of the merger and each holder of such SDTB option will be entitled to receive from Pacific Premier, as soon as reasonably practicable after the effective time of the merger, but in no event later than three (3) days after such effective time, a single lump sum cash payment equal to the product of (i) the number of shares of SDTB common stock subject to such SDTB option immediately prior to the closing of the merger, and (ii) the excess, if any, of the per share cash consideration over the exercise price per share of such SDTB option, less any applicable taxes required to be withheld with respect to such payment. If the exercise price per share of any such SDTB option is equal to or greater than the per share cash consideration, such SDTB option will be canceled without any cash payment being made in respect thereof.


When and How to Choose the Method of Payment for Your Shares (Page 60)

        Shares of SDTB common stock will be exchanged for either shares of Pacific Premier common stock, cash or a combination of stock and cash, as chosen by you, subject to the election and allocation procedures discussed herein and described in detail in the merger agreement. A form for making an election will be sent to you under separate cover no later than the date that this proxy statement/prospectus is mailed to holders of record of SDTB common stock. The election form permits you:

Table of Contents

        In order to make an effective election, you should complete the election form and return it as instructed with the stock certificates representing your shares of SDTB common stock. The election form must be received by the designated exchange agent by 5:00 p.m., Pacific Time approximately five business days prior to the closing date of the merger. After the election deadline you will not be able to change your election and you will be bound to the election you have made, subject to the allocation procedures described in this this proxy statement/prospectus.

        Your choice will be honored to the extent possible, but because of the overall limitation on the amount of cash and shares of Pacific Premier common stock available, whether you receive the amount of cash or stock you request will depend in part on how many other SDTB shareholders submit elections and how many choose to receive cash and how many choose to receive stock. Because 50% of the aggregate value of the merger consideration will paid in the form of shares of Pacific Premier common stock, and 50% of the aggregate merger consideration will be paid in cash, SDTB shareholders may not receive exactly the form of consideration that they elect and may receive a pro rata amount of cash and Pacific Premier common stock.

        Pacific Premier will not issue fractional shares. Instead, SDTB shareholders who receive Pacific Premier common stock will receive the value of any fractional share interest in cash, without interest, determined by multiplying such fractional interest by $13.41, which amount reflects the per share cash consideration, rounded to the nearest whole cent.

        After the election form and related transmittal materials have been received and processed and following the closing of the merger, you will be sent the cash and/or Pacific Premier common stock to which you are entitled. If you hold shares in street name, you will receive information from your broker or other holder of record advising you of the process for receiving the cash and/or Pacific Premier common stock to which you are entitled.

        You will need to surrender your SDTB common stock certificates to receive the appropriate merger consideration, but you should not send us any certificates now. You will receive detailed instructions on how to exchange your shares along with your election form and transmittal materials.

        The market price of Pacific Premier common stock and SDTB common stock will fluctuate prior to the date of the special meeting, the deadline for submitting your election regarding the merger consideration and the date you receive the merger consideration. SDTB shareholders should obtain a current price quotation for the shares of Pacific Premier common stock to update the implied value for a share of SDTB 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.

        SDTB has not declared or paid any dividends to date during 2013. SDTB declared and paid a 3% stock dividend in each of April 2011 and April 2012, respectively. As a California-chartered bank, SDTB is subject to bank regulatory restrictions on payment of dividends. Pursuant to the merger agreement, SDTB has certain restrictions on the payment of dividends to its shareholders pending the closing of the merger. See "The Merger—Business Pending the Merger" beginning on page 67.


Material Federal Income Tax Consequences of the Merger (Page 82)

        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 the proxy statement/prospectus as the Code, and it is a condition to completion of the merger that Pacific Premier and SDTB receive a legal opinion to that effect. If the merger is completed, the merger consideration that will be paid to the holders of SDTB common stock will include shares of Pacific Premier common stock (including cash for any fractional shares) and cash.

        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 proxy statement/prospectus, an SDTB shareholder that is a U.S. holder that receives solely shares of Pacific Premier common stock in exchange for all of its shares of SDTB common stock 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. An SDTB shareholder that is a U.S. Holder that receives solely cash in exchange for all of its shares of SDTB common stock generally will recognize gain or loss in connection with such exchange. An SDTB shareholder that receives shares of Pacific Premier common stock and cash in exchange for all of its shares of SDTB common stock generally will recognize gain (but not loss) on such exchange.

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

        Shareholders of record may vote by mail, telephone, via the Internet or by attending the special meeting and voting in person. Each proxy returned to SDTB by a holder of SDTB common stock, which is not revoked, 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 special meeting if necessary to permit further solicitation of proxies on the proposal to approve the merger agreement.


Approval of the Merger Agreement Requires the Affirmative Vote of Holders of Majority of the Issued and Outstanding Shares of SDTB Common Stock (Page 40)

        The affirmative vote of the holders of a majority of the issued and outstanding shares of SDTB common stock is necessary to approve the merger agreement on behalf of SDTB. At the close of business on the record date, there were 2,151,395 shares of SDTB common stock outstanding held by 152 holders of record. Each holder of record of SDTB common stock on the record date is entitled to one vote for each share held on all matters to be voted upon at the special meeting. If a SDTB shareholder does not vote, it will have the same effect as a vote against the merger agreement.

        Holders of 518,866 shares of SDTB common stock, representing approximately 24.1% of the outstanding shares of SDTB common stock, have signed shareholder agreements with Pacific Premier agreeing to vote in favor of the merger agreement.

        Due to the structure of the merger and the number of shares of Pacific Premier common stock to be issued to SDTB shareholders pursuant to the merger agreement, Pacific Premier shareholders are not required by law or Pacific Premier's amended and restated certificate of incorporation and amended and restated bylaws to adopt the merger agreement or approve the merger or the issuance of the Pacific Premier common stock in connection with the merger.


Management of SDTB Owns Shares Which May Be Voted at the Special Meeting (Page 41)

        As of the record date, the executive officers and directors of SDTB, as a group, held 518,866 shares of SDTB common stock, or approximately 24.1% of the outstanding SDTB common stock and have each entered into shareholder agreements with Pacific Premier and SDTB pursuant to which they have agreed, among other things, in their capacity as shareholders of SDTB, to vote their shares of SDTB common stock in favor of the merger agreement. The form of shareholder agreement is attached as Annex A to the merger agreement, which is attached as Appendix A to this proxy statement/prospectus.

SDTB's Shareholders Have Dissenters' Rights (Page 88)

        Under the CGCL, holders of SDTB common stock have the right to demand appraisal of their shares of SDTB common stock in connection with the merger and to receive, in lieu of the merger consideration, payment in cash, for the fair value of their shares of SDTB common stock. Any shareholder electing to exercise dissenters' rights must not have voted his, her or its shares of SDTB common stock "FOR" approval of the merger agreement and must comply with the provisions of the CGCL in order to perfect its rights of dissent and appraisal. Strict compliance with the statutory procedures is required to perfect dissenters' rights. These procedures are described later in this proxy statement/prospectus, and a copy of the relevant provisions of California law is attached as Appendix C.


SDTB is Prohibited from Soliciting Other Offers (Page 70)

        SDTB has agreed that, while the merger is pending, it will not solicit, initiate, encourage or, subject to some limited exceptions, engage in discussions with any third party other than Pacific Premier regarding extraordinary transactions such as a merger, business combination or sale of a material amount of assets or capital stock.


Pacific Premier and SDTB Must Meet Several Conditions to Complete the Merger (Page 64)

        Completion of the merger depends on meeting a number of conditions, including the following:

Table of Contents

        Unless prohibited by law, either Pacific Premier or SDTB could elect to waive a condition that has not been satisfied and complete the merger anyway. The parties cannot be certain whether or when any of the conditions to the merger will be satisfied, or waived where permissible, or that the merger will be completed.


Pacific Premier and SDTB Have Received Regulatory Approvals to Complete the Merger (Page 66)

        To complete the merger, the parties need the prior approval of the Board of Governors of the Federal Reserve System, or the Federal Reserve, and the California Department of Financial Institutions, or CA DFI. Pacific Premier and SDTB have received approval from each of these banking regulators for the merger.


Pacific Premier, the Bank and SDTB may Terminate the Merger Agreement (Page 72)

        Pacific Premier, the Bank and SDTB can mutually agree at any time to terminate the merger agreement before completing the merger, even if shareholders of SDTB have already voted to approve it.

        Pacific Premier and the Bank on one hand or SDTB on the other hand can also terminate the merger agreement:

        In addition, Pacific Premier may terminate the merger agreement at any time prior to the special meeting if the board of directors of SDTB withdraws or modifies its recommendation to the SDTB shareholders that the merger agreement be approved in any way which is adverse to Pacific Premier, or breaches its covenants requiring the calling and holding of a meeting of shareholders to consider the merger agreement and prohibiting the solicitation of other offers. Pacific Premier also may terminate the merger agreement if a third party commences a tender offer or exchange offer for 15% or more of the outstanding SDTB common stock and the board of directors of SDTB recommends that SDTB shareholders tender their shares in the offer or otherwise fails to recommend that they reject the offer within a specified period.

Termination Fee (Page 73)

Pacific Premier, the Bank and SDTB May Amend the Merger Agreement (Page 72)

        The parties may amend or supplement the merger agreement by written agreement at any time before the merger actually takes place; provided, however, no amendment may be made after the special meeting which by law requires further approval by the shareholders of SDTB without obtaining such approval.


SDTB's Directors and Officers Have Some Interests in the Merger that Are in Addition to or Different than Your Interests (Page 75)

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

        Assuming that the merger is consummated on June 30, 2013, upon the closing of the merger, pursuant to the terms of his confidentiality, non-competition and non-solicitation agreement with the Bank, as well as his employment agreement, SDTB stock options and other contractual arrangements with SDTB, Mr. Perry will be entitled to receive an aggregate of $3,274,475, on a pre-tax basis. In addition, Pacific Premier will assume SDTB's obligations under the Supplemental Executive Retirement Plans with Mr. Perry and Mr. Perry's deferred compensation agreement to pay Mr. Perry an aggregate amount of $3,586,690 over the next 15 years, for which Pacific Premier will accrue a liability upon the closing of the merger, in addition to SDTB's existing liability, in the amount of $1,648,151 on a pre-tax basis.

        The following is a tabular presentation of the payments and benefits payable to Mr. Perry in connection with the merger, as described above. The amounts set forth in the table below are approximate and based upon the assumption that the merger is completed on June 30, 2013. An earlier or later closing date for the merger would cause certain of the amounts to change, although any such changes are not expected to be material.

        The cash portion of the merger consideration will be subject to downward adjustment if SDTB's aggregate transaction-related expenses exceed $3.0 million, on an after-tax equivalent basis. Pursuant to the terms of the merger agreement, SDTB's transaction-related expenses consist of certain fixed amounts, such as SDTB's accounting and advisory fees and expenses associated with the accrual of benefits and payments payable to Mr. Perry described above, which are estimated to amount to $2.7 million in the aggregate on an after-tax basis, of which $2.5 million is associated with the accrual of benefits and payments payable to Mr. Perry described above. SDTB's transaction-related expenses also consist of certain amounts that are not fixed, such as SDTB's legal fees and premiums for extended directors' and officers' liability insurance to the extent premiums exceed 200% of current SDTB premiums. To the extent that the variable amounts cause SDTB's aggregate transaction-related expenses to exceed $3.0 million, on an after-tax equivalent basis, and the cash portion of the merger

consideration is reduced by such excess, all of SDTB's transaction-related expenses, including the payments made to Mr. Perry, the liability accrued by Pacific Premier related to future payments to Mr. Perry and the premiums for extended directors' and officers' liability insurance, to the extent premiums exceed 200% of current SDTB premiums, will have the effect of reducing the merger consideration payable to SDTB's shareholders. The cash portion of the merger consideration is not subject to an upward adjustment if SDTB's aggregate transaction-related expenses are less than $3.0 million, on an after-tax equivalent basis. Although no assurances can be made as to the final amount of SDTB's aggregate transaction-related expenses, SDTB does not anticipate that its variable transaction-related expenses will cause its aggregate transaction-related expenses to exceed $3.0 million.

        The board of directors of SDTB was aware of the foregoing interests and considered them, among other matters, in approving the merger agreement and the merger.


Accounting Treatment of the Merger (Page 85)

        The merger will be accounted for under the purchase method of accounting under generally accepted accounting principles, or GAAP.


Shareholders of Pacific Premier and SDTB Have Different Rights (Page 127)

        The rights of shareholders of Pacific Premier differ from the rights of shareholders of SDTB. Pacific Premier is incorporated under the laws of the State of Delaware and SDTB is incorporated under the laws of the State of California. The rights of holders of Pacific Premier common stock are governed by the Delaware General Corporation Law, or DGCL, as well as its amended and restated certificate of incorporation and amended and restated bylaws, and the rights of holders of SDTB common stock are governed by the California Financial Code and the CGCL, as well as its articles of incorporation and bylaws.

SELECTED UNAUDITED PRO FORMA COMBINED
CONSOLIDATED FINANCIAL DATA

        The following table presents selected audited financial data for Pacific Premier at and for the year ended December 31, 2012 (i) on an actual historical basis; (ii) on an as adjusted basis after giving effect to the sale of 495,000 newly issued shares of Pacific Premier common stock in January 2013 in connection with the underwriters' exercise of the over-allotment option in Pacific Premier's recently completed underwritten public offering and the completion of the acquisition of FAB by Pacific Premier on March 15, 2013, including the issuance of 1,279,217 shares of Pacific Premier common stock and payment of $37.2 million in cash as consideration to the holders of FAB common stock in exchange for their shares; and (iii) on a pro forma combined basis for the merger, after giving effect to the pro forma adjustments described in the notes to the unaudited pro forma combined financial statements appearing in this proxy statement/prospectus beginning on page 120, as further adjusted after giving effect to (A) the sale of 495,000 newly issued shares of Pacific Premier common stock in connection with the underwriters' exercise of the over-allotment option in Pacific Premier's recently completed underwritten public offering and (B) the recently completed acquisition of FAB. The pro forma data in the table assumes that the merger is accounted for using the purchase method of accounting and does not give effect to the cost savings that may be realized in the merger. See "The Merger—Accounting Treatment of the Merger" on page 85.

UNAUDITED COMPARATIVE PER SHARE DATA

        The following table sets forth certain historical, pro forma and pro forma equivalent per share financial information for Pacific Premier common stock and SDTB common stock. The pro forma and pro forma equivalent per share information in the table gives effect, for the twelve month period ended December 31, 2012, to (i) the sale of 495,000 newly issued shares of Pacific Premier common stock in January 2013 in connection with the underwriters exercise of the over-allotment option in Pacific Premier's recently completed underwritten public offering; (ii) the acquisition of FAB by Pacific Premier on March 15, 2013, including the issuance of 1,279,217 shares of Pacific Premier common stock and payment of $37.2 million in cash as consideration to the holders of FAB common stock in exchange for their shares; and (iii) the merger as if the transaction had been effective on the last date of the respective periods, in the case of book value data, and as if the transaction had been effective on the first day of the respective periods, in the case of the income and dividend data. The pro forma information in the table assumes that the merger is accounted for under the purchase 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 has presented in its prior filings with the Commission about Pacific Premier and FAB and the historical financial information of SDTB that appears elsewhere in this proxy statement/prospectus. See "Where You Can Find More Information" beginning on page 136 and "Index to SDTB Financial Statements" beginning on page F-1.

        On March 15, 2013, Pacific Premier completed its acquisition of FAB, which operated from its headquarters in Dallas, Texas. In connection with the consummation of the FAB acquisition, Pacific Premier issued 1,279,217 shares of its common stock and $37.2 million in cash as consideration to the holders of FAB common stock in exchange for their shares. On December 11, 2012, Pacific Premier completed an underwritten public offering of 3.3 million shares of its common stock at a public offering price of $10.00 per share. The net proceeds from the offering after deducting underwriting discounts and commissions was $31.2 million. On January 9, 2013, Pacific Premier issued an additional 495,000 shares of its common stock at a public offering price of $10.00 per share in connection with the underwriters' exercise of the over-allotment option granted to them as part of the offering. The net proceeds from the over-allotment after deducting underwriting discounts and commissions was $4.7 million.

The amount reflects the sale of 495,000 newly issued shares of Pacific Premier common stock on January 9, 2013 in connection with the underwriters' exercise of the over-allotment option granted to them as part of an underwritten public offering as if such shares were issued on January 1, 2012. However, the amount does not reflect the use of the approximately $4.7 million of net proceeds received by Pacific Premier in connection with the sale of such shares for the period presented.

(2)
Pro forma combined amounts are calculated by adding together the historical amounts reported by Pacific Premier and FAB, as adjusted for the estimated purchase accounting adjustments to be recorded in connection with the merger and the 1,279,217 shares of Pacific Premier common stock that were issued in connection with the FAB acquisition.

(3)
Pro forma combined amounts are calculated by adding together the historical amounts reported by Pacific Premier, FAB and SDTB, as adjusted for the estimated purchase accounting adjustments to be recorded in connection with the mergers and the 1,279,217 shares of Pacific Premier common stock issued in the FAB acquisition and an estimated 1,198,327 shares of Pacific Premier common stock to be issued in connection with the merger.

(4)
The equivalent pro forma per share data for SDTB is computed by multiplying the pro forma combined amounts by the exchange ratio of 1.114.

(5)
Because Pacific Premier does not pay dividends on its common stock, the equivalent pro forma cash dividends per common share is zero.

Table of Contents


RISK FACTORS

        Prior to deciding whether or not to approve the merger agreement, SDTB shareholders should be aware of and carefully read and consider the following risks and uncertainties that are applicable to the merger agreement, the merger and Pacific Premier. SDTB shareholders 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, as amended, for the year ended December 31, 2012 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 proxy statement/prospectus by reference. See "Where You Can Find More Information" beginning on page 136.

SDTB shareholders may not receive the exact amount of the form of consideration that they elect.

        SDTB shareholders will have the opportunity to elect to receive either stock or cash consideration, or a combination thereof, for all shares of SDTB common stock held by them. However, the ability of an SDTB shareholder to receive the exact amount or his, her or its elected form of merger consideration is limited by the requirement that 50% of the aggregate value of the merger consideration be paid in the form of shares of Pacific Premier common stock, and 50% of the aggregate value of the merger consideration be paid in cash. The merger agreement contains proration and allocation methods to achieve this desired result. If SDTB shareholders elect to receive more than 50% of the aggregate value of the merger consideration in the form of shares of Pacific Premier common stock, the elections will be reallocated so that 50% of the aggregate value of the merger consideration is paid in the form of shares of Pacific Premier common stock. If SDTB shareholders elect to receive more than 50% of the aggregate value of the merger consideration in the form of cash, the elections will be reallocated so that 50% of the aggregate value of the merger consideration is paid in the form of cash. Therefore, SDTB shareholders may not receive the exact amount of the form of consideration that they elect.

Because the market price of Pacific Premier common stock will fluctuate, you cannot be sure of the exact value of the per share stock consideration you will receive.

        Upon the effective time of the merger, each share of SDTB common stock will be cancelled and converted into the right to receive merger consideration, consisting of shares of Pacific Premier common stock and/or cash, pursuant to the terms of the merger agreement. The value of the per share stock consideration to be received by SDTB shareholders will be based on an exchange ratio, and will fluctuate depending on the average closing prices per share of Pacific Premier common stock during the 10 consecutive trading day period ending on (and including) the fifth trading day prior to the closing date of the merger, or the PPBI Average Share Price. The PPBI Average Share Price may vary from the market price of Pacific Premier common stock on the date the merger was announced, on the date that this proxy statement/prospectus is mailed to SDTB shareholders, on the date that you elect the form of merger consideration that you wish to receive, on the date that you vote on the merger agreement and on the date of the special meeting. The exchange ratio of 1.114 shares of Pacific Premier common stock for each share of SDTB common stock is subject to (i) downward adjustment if the PPBI Average Share Price is greater than $13.240 and (ii) upward adjustment if the PPBI Average Share Price is less than $10.832. Any change in the price of Pacific Premier common stock prior to the date that the exchange ratio is set will affect the value of the merger consideration that you will receive upon the effective time of the merger.

        Because the price of Pacific Premier common stock could fluctuate during the period of time when you elect the form of merger consideration that you wish to receive and the time you actually receive your shares of Pacific Premier common stock as merger consideration, you will be subject to the risk of a decline in the price of Pacific Premier common stock during this period. SDTB does not have the right to terminate the merger agreement or to resolicit the vote of its shareholders solely because of

31


Table of Contents

changes in the market prices of Pacific Premier's common stock. Any adjustment to the per share stock consideration is subject to the limitation that the number of shares of Pacific Premier common stock issued at the closing of the merger may not exceed 19.9% of the outstanding shares of Pacific Premier common stock, which is referred to in this proxy statement/prospectus as the stock limit. If the stock limit is reached, no further adjustment will be made to any other merger consideration to be paid to SDTB's shareholders, and the aggregate number of shares of Pacific Premier common stock to be issued will be equal to 19.9% of the outstanding shares of Pacific Premier common stock immediately prior to the closing date. 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, 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 you elect the form of merger consideration that you wish to receive and at the time of the special meeting, you will not know or be able to calculate the exact value of the shares of Pacific Premier common stock you will receive upon completion of the merger.

        Pacific Premier's common stock is traded on the NASDAQ Global Market under the trading symbol "PPBI," but there has historically been a relatively low trading volume in its common stock. Although Pacific Premier recently completed a public offering of its securities, issued additional shares of common stock in connection with the completion of the FAB acquisition and expects to issue additional shares of common stock in the merger to holders of SDTB common stock, Pacific Premier may continue to experience a limited trading market for its common stock, which may cause fluctuations in the market value of its common stock to be exaggerated, leading to price volatility in excess of that which would occur in a more active trading market of its common stock. Future sales of substantial amounts of Pacific Premier common stock in the public market, or the perception that such sales may occur, could adversely affect the prevailing market price of Pacific Premier common stock. In addition, even if a more active market in Pacific Premier common stock develops, Pacific Premier cannot assure SDTB shareholders that such a market will continue.

Because the cash portion of the merger consideration is subject to adjustment, you cannot be sure of the exact value of the per share cash consideration that you will receive upon completion of the merger.

        The per share cash consideration to be received in the merger may be subject to downward adjustment in the event that SDTB's expenses related to the merger exceed $3.0 million, on an after-tax equivalent basis. As a result of the potential downward adjustment, SDTB shareholders will not know the amount of the per share cash consideration that will be payable to shareholders of SDTB when they elect the form of merger consideration that they wish to receive or vote on the merger agreement at the special meeting. SDTB does not have the right to terminate the merger agreement or to resolicit the vote of its shareholders solely because of changes in the per share cash consideration that may occur.

The federal income tax consequences of the merger for SDTB shareholders will depend on the merger consideration received.

        The federal income tax consequences of the merger to you will depend on the form of merger consideration that you receive. You generally will not recognize any gain or loss on the exchange of your shares of SDTB common stock solely for shares of Pacific Premier common stock (other than cash received in lieu of any fractional shares of Pacific Premier common stock). However, you generally will recognize gain or loss on the exchange of all of your shares of SDTB common stock solely for cash. Finally, you generally will recognize gain (but not loss) if you receive a combination of shares of Pacific Premier common stock and cash in exchange for your shares of SDTB common stock. See "The Merger—The Merger Consideration" beginning on page 57. For a detailed discussion of the federal

32

income tax consequences to you of the merger, see "The Merger—Material Federal Income Tax Consequences" beginning on page 82.

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

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

        Assuming that the merger is consummated on June 30, 2013, the aggregate amount payable to Mr. Perry in connection with the consummation of the merger is approximately $3,274,475. In addition, Pacific Premier will assume SDTB's obligations under the Supplemental Executive Retirement Plans

33


Table of Contents

with Mr. Perry and Mr. Perry's deferred compensation agreement to pay Mr. Perry an aggregate amount of $3,586,690 over the 15 years following the closing of the merger.

        To the extent that the variable amounts of SDTB's transaction-related expenses, such as SDTB's legal fees and premiums for extended directors' and officers' liability insurance to the extent premiums exceed 200% of current SDTB premiums, cause SDTB's aggregate transaction-related expenses to exceed $3.0 million, on an after-tax equivalent basis, and the cash portion of the merger consideration is reduced by such excess, all of SDTB's transaction-related expenses, including the payments made to Mr. Perry, the liability accrued by Pacific Premier related to future payments to Mr. Perry and the premiums for extended directors' and officers' liability insurance, to the extent premiums exceed 200% of current SDTB premiums, will have the effect of reducing the merger consideration payable to SDTB's shareholders.

        These arrangements may create potential conflicts of interest. These interests of SDTB's directors and officers may cause some of these persons to view the proposed transaction differently than you view it, as a shareholder. The SDTB board of directors was 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. SDTB shareholders should consider these interests in conjunction with the recommendation of the SDTB board of directors with respect to approval of the merger. See "The Merger—Interests of Certain SDTB Officers and Directors in the Merger" beginning on page 75.

If you are an SDTB shareholder and you make a valid cash or stock election, you will not be able to sell your shares during certain times.

        If you are an SDTB shareholder of record as of the record date for the special meeting and hold your shares in certificated form, you will have to deliver a properly completed and signed form of election and your stock certificates to the exchange agent in order to make a valid cash or stock election. For further details on the determination of the election deadline, see "The MergerThe Merger Consideration—Election Procedures" beginning on page 60. The election deadline will be the fifth (5th) business day prior to the completion of the merger. You will not be able to sell any certificated shares of SDTB common stock that you have delivered as part of your election unless you revoke your election before the deadline by providing written notice to the exchange agent. If you do not revoke your election before the election deadline, you will not be able to sell any of your shares of SDTB common stock for any reason until you receive cash and/or Pacific Premier common stock following completion of the merger. Similarly, holders of book-entry shares of SDTB common stock who have made a valid election and have not revoked their election prior to the election deadline will not be able to sell any shares for which they have made a valid election after the election deadline. In the time between the election deadline and the completion of the merger, the trading price of SDTB or Pacific Premier common stock may decrease, and you might otherwise want to sell your shares of SDTB common stock to gain access to cash, make other investments, or reduce the potential for a decrease in the value of your investment. The date that you will receive your merger consideration depends on the completion date of the merger, which is uncertain. The completion date of the merger might be later than expected due to unforeseen events, such as delays in obtaining regulatory approvals.

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

        Until the completion of the merger, with some limited exceptions, SDTB 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, SDTB has agreed to pay a termination fee to Pacific Premier in specified circumstances. These provisions could discourage

Table of Contents

other companies from trying to acquire SDTB even though those other companies might be willing to offer greater value to SDTB shareholders than Pacific Premier has offered in the merger. The payment of the termination fee could also have a material adverse effect on SDTB's financial condition.

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 to combine the businesses of Pacific Premier and SDTB in a manner that does not materially disrupt the existing customer relationships of SDTB 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 SDTB 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 will also divert management attention and resources. These integration matters could have an adverse effect on each of Pacific Premier and SDTB 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 SDTB or Pacific Premier currently.

        Upon completion of the merger, holders of SDTB common stock receiving the per share stock consideration will become holders of Pacific Premier common stock. Pacific Premier's business differs from that of SDTB, 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 SDTB.

The fairness opinion obtained by SDTB from its financial advisor, KBW, will not reflect changes in circumstances between the date of the merger agreement and the completion of the merger.

        Changes in the operations and prospects of SDTB or Pacific Premier, general market and economic conditions and other factors that may be beyond the control of SDTB and Pacific Premier, and on which the fairness opinion delivered by KBW to SDTB was based, may alter the value of SDTB or Pacific Premier or the market price for shares of SDTB common stock or Pacific Premier common stock by the time the merger is completed. The fairness opinion does not speak as of any date other than the date of such opinion, which was March 5, 2013, and the fairness opinion does not address the fairness of the merger consideration, from a financial point of view, at the time SDTB shareholders will be voting at the special meeting or upon completion of the merger. The merger agreement does not require that the fairness opinion of KBW be updated as a condition to the completion of the merger, and SDTB does not intend to request that the fairness opinion be updated. The fairness opinion is attached as Appendix B to this proxy statement/prospectus. For a description of the opinion that SDTB received from KBW, see "The Merger—Opinion of SDTB's Financial Advisor" beginning on page 49. For a description of the other factors considered by SDTB's board of directors in determining to approve the merger, see "The Merger—SDTB's Reasons for the Merger" beginning on page 47.

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 price of Pacific Premier common stock and SDTB common stock to decline.

        The merger is subject to customary conditions to closing, including the receipt of the approval of the SDTB shareholders. 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 SDTB may terminate the merger agreement under certain circumstances even if the merger is approved by SDTB shareholders, including if the merger has not been completed on or before September 30, 2013. If the merger is not completed, the respective trading prices of Pacific Premier common stock on the Nasdaq Global Market and of SDTB common stock on the OTCQB 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 64.

The actual financial condition and results of operations of the combined company following the merger may not be consistent with, or evident from, these unaudited pro forma condensed combined financial data. In addition, the assumptions used in preparing the unaudited pro forma condensed combined financial data may not prove to be accurate, and other factors may affect the combined company's financial condition or results of operations following the merger. Any potential decline in the combined company's financial condition or results of operations may cause significant variations in the stock price of the combined company.

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

        Upon completion of the merger, SDTB shareholders will become Pacific Premier shareholders and their rights as shareholders will be governed by the Pacific Premier amended and restated certificate of incorporation and the Pacific Premier amended and restated bylaws. The rights associated with SDTB common stock are different from the rights associated with Pacific Premier common stock. See "Comparison of the Rights of Shareholders" beginning on page 127.

The purposes of the special meeting are to consider and vote upon a proposal to approve the merger agreement among Pacific Premier, the Bank and SDTB, which provides, among other things, for the merger, and a proposal to adjourn the special meeting to the extent necessary to solicit additional votes on the merger agreement.

        This document also constitutes a prospectus of Pacific Premier relating to the Pacific Premier common stock to be issued upon completion of the merger to holders of SDTB common stock as part of the merger consideration. See "The Merger—The Merger Consideration" beginning on page 57. Based on 2,151,395 shares of SDTB common stock outstanding on May 9, 2013, an exchange ratio of 1.114, and the fact that 50% of the outstanding shares of SDTB common stock will be converted into the right to receive the per share stock consideration, approximately 1,198,327 shares of Pacific Premier common stock will be issuable to shareholders of SDTB upon completion of the merger as payment of the aggregate per share stock consideration.

Recommendation of the SDTB Board of Directors

        The SDTB board of directors has unanimously approved the merger agreement and the transactions contemplated by the merger agreement. Based on SDTB's reasons for the acquisition described in this proxy statement/prospectus, including the fairness opinion of KBW, the board of directors of SDTB believes that the merger is in the best interests of SDTB's shareholders and unanimously recommends that SDTB shareholders vote "FOR" approval of the merger agreement. See "The Merger—SDTB's Reasons for the Merger" beginning on page 47. The SDTB board of directors also unanimously recommends that SDTB shareholders vote "FOR" the proposal to adjourn the 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 May 9, 2013 has been fixed by SDTB as the record date for the determination of SDTB shareholders entitled to notice of and to vote at the special meeting and any adjournment or postponement of the special meeting. At the close of business on the record date, there were 2,151,395 shares of SDTB common stock outstanding and entitled to vote, held by approximately 152 holders of record. Each share of SDTB common stock entitles the holder to one vote at the special meeting on all matters properly presented at the meeting.


How to Vote Your Shares

        Shareholders of Record.    Shareholders of record may vote by mail, telephone, via the Internet or by attending the special meeting and voting in person. If a SDTB 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 Thursday, June 20, 2013.

        Shares Held in "Street Name."    If a SDTB shareholder's shares of SDTB common stock are held through a bank, broker or other nominee, such SDTB shareholder is considered the beneficial owner of such shares held in "street name." In such case, this proxy statement/prospectus has been forwarded by such SDTB shareholder's bank, broker or other nominee, who is considered, with respect to such shares, the shareholder of record. As the beneficial owner, a SDTB 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 SDTB shareholder. Without specific instructions from the SDTB shareholder, the bank, broker or other nominee is not empowered to vote a SDTB shareholder's shares on non-routine matters such as the proposal to approve the merger agreement or the proposal of the SDTB board of directors to adjourn the special meeting, if necessary. Not voting these shares will have the effect of voting against the approval of the merger agreement and not voting these shares will also have the effect of voting against any proposal of the SDTB board of directors to adjourn the special meeting if the number of affirmative votes cast for the proposal is either (i) not a majority of votes cast or (ii) a majority of the votes cast but such majority does not constitute a majority of the quorum required to transact business at the special meeting. 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 SDTB 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 special meeting, if necessary, by using the voting instruction card provided to such SDTB shareholder by his or her bank, broker or other nominee. Alternatively, if a SDTB shareholder is a beneficial owner and wishes to vote in person at the special meeting, the SDTB shareholder must provide a proxy executed in such SDTB shareholder's favor by the bank, broker or other nominee.

Revocation of Proxies

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

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

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

        Each proxy returned to SDTB (and not revoked) by a holder of SDTB 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 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 special meeting, must be present in person or by proxy before any action may be taken at the special meeting. Once a share of SDTB common stock is represented at the special meeting, it will be counted for the purpose of determining a quorum not only at the special meeting but also at any adjournment or postponement of the special meeting. In the event that a quorum is not present at the special meeting, it is expected that the 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 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 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 SDTB common stock is necessary to approve the merger agreement on behalf of SDTB. The proposal to adjourn the special meeting if necessary to permit further solicitation of proxies must be approved by the affirmative vote

40


Table of Contents

of a majority of the shares of SDTB common stock represented and voting at the special meeting, which shares voting affirmatively must also constitute at least a majority of the required quorum.

        Because the vote required to approve the merger agreement is a majority of outstanding shares of SDTB common stock, abstentions and broker non-votes of shares of SDTB common stock will have the same effect as a vote against the proposal to approve of the merger agreement.

        With respect to the proposal of the SDTB board of directors to adjourn the special meeting, abstentions and broker non-votes of shares of SDTB common stock will not have any effect on this adjournment proposal, if the number of affirmative votes cast for this proposal is a majority of the votes cast and such votes also constitute a majority of the quorum required to transact business at the special meeting. 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 SDTB board of directors to adjourn the special meeting.


Shares of SDTB Subject to Voting Agreements

        The directors and executive officers of SDTB, who collectively own and have the power to vote approximately 24.1% of the outstanding shares of SDTB common stock as of May 9, 2013, 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 87.

        As of the close of business on the record date for the special meeting, Pacific Premier did not beneficially own any shares of SDTB common stock.


Solicitation of Proxies

        SDTB will pay for the costs of mailing this 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 on behalf of its board of directors. In addition to solicitation by mail, the directors, officers and employees of SDTB may solicit proxies from shareholders of SDTB in person or by telephone, facsimile or other electronic methods without compensation other than reimbursement for their actual 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 SDTB will reimburse such custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses in connection therewith.


Attending the Special Meeting

        All holders of SDTB 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 special meeting. Shareholders of record can vote in person at the special meeting. If a SDTB shareholder is not a shareholder of record and would like to vote in person at the special meeting, such SDTB shareholder must produce a proxy executed in his or her favor by the record holder of such SDTB shareholder's shares. In addition, such SDTB shareholder must bring a form of personal photo identification with him or her in order to be admitted at the special meeting. SDTB 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 special meeting is prohibited without SDTB's express written consent.

Adjournments and Postponements

        Although it is not currently expected, the 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 special meeting to approve the proposal to approve the merger agreement or if a quorum is not present at the special meeting. Other than an announcement to be made at the 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 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 special meeting as adjourned or postponed.


Questions and Additional Information

        If a SDTB shareholder has questions about the merger or the process for voting or if additional copies of this document or a replacement proxy card are needed, please contact Michael E. Perry, SDTB's Chairman, President and Chief Executive Officer, at (619) 525-1727, or Toby Reschan, SDTB's Senior Executive Vice President and Chief Operating Officer, at (619) 525-1728.


THE MERGER
(PROPOSAL ONE)

        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 proxy statement/prospectus, including the merger agreement which is attached as Appendix A. You should carefully read the appendices in their entirety.


Structure of the Merger

        Pursuant to the terms and conditions set forth in the merger agreement, SDTB will be acquired by Pacific Premier whereby SDTB will merge with and into the Bank, with the Bank as the surviving institution. Following consummation of the merger, Pacific Premier intends to continue to operate all of the branches acquired from SDTB.

        Following the consummation of the merger, the Bank's articles of incorporation, as amended, and the amended and restated bylaws, as amended, as in effect immediately prior to the merger will continue as the articles of incorporation and the bylaws of the Bank. The directors and executive officers of the Bank immediately prior to the merger will continue as the directors and executive officers of the Bank after the merger, in each case until their respective successors are duly elected or appointed and qualified.


Background of the Merger

        Since the beginning of 2011, five independent community banks in San Diego County, California announced their sale to larger banks with greater resources. The board of directors of SDTB had considered some of these independent community banks that sold as potential merger partners that would contribute to building a larger San Diego-based community bank, but those potential opportunities disappeared with the sale announcements. The branches of these acquired community banks became stronger competitors of SDTB with access to more capital and gained the ability to offer expanded banking products and services to their customers.

        Throughout the fourth quarter of 2011 and the first quarter of 2012, the board of directors of SDTB discussed the many challenges facing the community banking industry, including the sluggish economic recovery, lack of meaningful demand for credit, increased regulatory burden and related expenses, and the Federal Reserve's extended zero interest rate policy. One issue of special concern to

42


Table of Contents

SDTB was SDTB's investment securities portfolio which has historically generated a substantial portion of its income. The board of directors of SDTB recognized that if the current low interest rate environment continued as projected by the Federal Reserve, SDTB's higher yielding investment securities would mature and SDTB would be replacing them with lower yielding investment securities, which would significantly reduce SDTB's net income. Additionally, the board of directors of SDTB identified that its ability to increase its revenues by generating a meaningful amount of loans in the wake of the sluggish economic recovery was going to be a challenge for SDTB. In light of the foregoing and the challenging operating environment facing SDTB, the board of directors of SDTB concluded that it would be appropriate to explore the possibility of a strategic alliance or merger and instructed Michael E. Perry, SDTB's Chairman, President and Chief Executive Officer, to meet with various investment banking firms to begin considering SDTB's strategic alternatives. During the first quarter of 2012, SDTB contacted KBW, as well as a couple of other investment banks, to seek input on the M&A environment and various strategic alternatives that might be in the best interest of SDTB's shareholders.

        In mid-April 2012, SDTB began working with KBW to assist it in identifying potential strategic partners. SDTB engaged KBW as its exclusive financial advisor in November 2012. As summarized below, SDTB and KBW had conversations and/or meetings between April 2012 and October 2012, with no less than 20 different parties to gauge such parties' interest in a potential strategic transaction with SDTB. Nine potential partners, including Pacific Premier, entered into confidentiality agreements with SDTB and were provided access to SDTB's confidential information for review. Of the nine potential partners, five parties communicated either verbally or in writing proposals to acquire SDTB, which proposals were inferior to the proposal submitted by Pacific Premier. These five other proposals were inferior for a variety of reasons including a lower valuation, lack of liquidity, uncertainty of the consideration being offered, uncertainty regarding timing or a lower probability of success associated with closing the transaction.

        When SDTB started the process of analyzing potential strategic transactions, SDTB did not wish to disrupt its current operations and was concerned about confidentiality. Therefore, after discussing these matters with KBW, and before starting the process, it was agreed that it would be appropriate to contact a limited number of potential transaction partners, determine their interest in a potential transaction, and then contact additional potential transaction partners as the initial contacts were determined not to have sufficient interest. Initially, SDTB authorized KBW to contact five parties who were deemed to have interest in the San Diego market and had business models that were a good fit with SDTB. If a party informed KBW or SDTB that it had limited or no interest, the approach was to open up the process to additional potential partners. By the end of April 2012, eight parties had been contacted, with one stating that SDTB did not currently fit in its business plan. SDTB had one meeting with a potential partner in April 2012.

        In May 2012, five additional parties were contacted. As a result of the contacts made in April and in May, SDTB had seven additional meetings with potential partners. By the end of May, there were two parties that were conducting extensive due diligence of SDTB, having ongoing dialogues with SDTB management and KBW and/or were analyzing financial models of a potential acquisition transaction with SDTB. After conducting some limited due diligence, one party in June 2012 advised that they were not going to pursue an acquisition transaction at that time due to other priorities and that they would revisit a potential acquisition transaction with SDTB later in the summer. That party continued to delay its consideration of a transaction with SDTB until early October 2012, when it finally met with SDTB's management. However, after this meeting, SDTB and this party did not pursue a transaction due to the party's operational constraints. The second party continued its discussions with SDTB in June 2012 and their review and analysis of SDTB's due diligence materials. In early July 2012, the second party informed SDTB that it would be willing to proceed with further dialogue only if SDTB was willing to do a transaction at "book value" or a slight premium to book and expressed

43


Table of Contents

concerns of a lack of loan demand, large re-pricing risk in the securities portfolio and continual net interest margin compression. SDTB was unable to obtain an increase in this party's offer as the party cited the uncertainty in the market and its expectation of a weak economic outlook. The board of directors of SDTB decided that the indicated valuation level contained in this party's offer was not in the best interest of its shareholders and instructed KBW to continue to explore other alternatives.

        In July 2012, SDTB met with two other parties that were interested in pursuing a potential acquisition transaction. One party did not have any prior experience in acquisitions and its securities were thinly traded, which would not result in a meaningful increase in liquidity to SDTB shareholders. This party initially indicated verbally that it would consider a 100% stock transaction on a book for book exchange. SDTB continued discussions with this party until August 2012, when such party did not submit any written offer to SDTB and it was decided not to pursue a transaction. Also, in July 2012, a private equity backed bank, or Party A, approached SDTB and held an initial meeting with SDTB management to express its desire to explore a strategic transaction with SDTB. Party A continued to hold exploratory meetings with management of SDTB throughout the summer and fall of 2012.

        By the end of August 2012, KBW and SDTB had contacted 17 different parties, with 11 parties declining to pursue further dialogue for various reasons. KBW believed that it had conducted a thorough market check and suggested to SDTB's board of directors that the board of directors should bring the remaining open dialogues to a conclusion so as to avoid any unnecessary disruption to SDTB's operations. The board of directors of SDTB agreed, although it requested KBW continue to evaluate potential strategic transactions.

        In late August 2012, a privately held local bank approached SDTB and, in September and October 2012, conducted due diligence and had several meetings with SDTB management. In mid-October, this local bank verbally suggested doing a 100% stock deal, valuing SDTB common stock at book value. SDTB's board of directors concluded that merging with a larger bank that could provide increased liquidity to its shareholders at a higher price would be in the best interests of its shareholders. SDTB continued discussions with this local bank through January 2013, but the local bank did not enhance its offer.

        In September and October 2012, three additional banks communicated potential interest, one of which was Pacific Premier. The other two banks did not submit any proposals. By the end of October, SDTB asked KBW to approach both Pacific Premier and Party A to solicit written initial indications of interest. SDTB formed a Special Committee of its board of directors, including the Chair of its Audit Committee, Lead Outside Director, and Chair of the Executive Compensation Committee, to assist in the negotiation of any potential letters of interest.

        On November 7, 2012, Party A submitted an initial indication of interest to SDTB with potential consideration to SDTB's shareholders that equated to 1.15 times book value after deal expenses as of September 30, 2012, with 50% payable in cash and 50% payable in stock. Pacific Premier submitted its initial indication of interest on November 13, 2012, with potential consideration to SDTB's shareholders that equated to 1.10 times book value after deal expenses as of September 30, 2012, with 50% payable in cash and 50% payable in stock.

        The board of directors of SDTB met on November 15, 2012 to consider the two offers and subsequently asked KBW to engage in negotiations with both parties. Party A entered into an active negotiation with KBW and SDTB over the following two weeks, which resulted in Party A increasing the consideration payable to SDTB's shareholders to 1.20 times book value after deal expenses as of September 30, 2012, with 50% payable in cash and 50% payable in stock. Pacific Premier did not increase its offer. A factor that SDTB's board of directors considered was that the book value included a substantial "unrealized gain" in SDTB's securities portfolio, which was subject to volatility and fluctuated daily depending on the market level of interest rates.

        After thorough dialogue and much deliberation of the two proposals, on November 30, 2012, SDTB's board of directors decided to move forward on an exclusive basis with Party A. SDTB and Party A engaged in two weeks of extensive due diligence on one another. On December 13, 2012, the parties were unable to reach agreement on a transaction and mutually agreed to terminate their discussions.

        On December 14, 2012, SDTB contacted Pacific Premier to inform it that SDTB's exclusive negotiations with Party A had terminated. Pacific Premier then advised SDTB that it was still interested in pursuing a transaction with SDTB and began conducting additional due diligence of SDTB. On January 16, 2013, Pacific Premier submitted a revised offer letter to SDTB with total consideration payable to SDTB's shareholders (including option holders) of approximately $30 million, with 50% payable in cash and 50% payable in Pacific Premier common stock. On January 23rd, following its meeting of its board of directors, SDTB countered Pacific Premier's offer, requesting that Pacific Premier: (i) Fix the exchange ratio related to the stock portion of the consideration, (ii) Increase the consideration to shareholders by $500,000, (iii) Absorb all deal expenses, including any and all change in control payments, severance payments, investment banking fees, etc., up to $3,000,000 on an after-tax basis, (iv) Fix the cash portion of the consideration, and (v) Allow the earnings through close to accrue to the shareholders of SDTB. On January 25, 2013, Pacific Premier responded with a final proposal that increased its offer to $30.6 million, 50% of which would be payable in cash and 50% would be payable as stock, included a fixed exchange ratio for the stock portion of the merger consideration within 10% range of the value of Pacific Premier common stock as of the signing of the merger agreement and included Pacific Premier paying all of SDTB's deal expenses, including any and all change in control payments, severance payments, investment banking fees, etc., up to $3,000,000 on an after-tax basis.

        As part of its due diligence of SDTB, Pacific Premier was aware of the contractual obligations and other compensation arrangements of SDTB, including those with Mr. Perry pursuant to his employment agreement and other compensation arrangements that would involve payments in connection with a change in control transaction, such as the merger. Because the cash payments and other benefits payable to Mr. Perry were set forth in existing contractual arrangements with SDTB, with the exception of the payments pursuant to the confidentiality, non-competition and non-solicitation agreement, the amounts payable to Mr. Perry pursuant to such arrangements, which are included as part of the SDTB deal expenses to be reimbursed by Pacific Premier, were not negotiated. In connection with the merger, Pacific Premier made the decision not to retain Mr. Perry after the completion of the merger and accordingly his existing employment agreement with SDTB that is currently set to expire on December 31, 2015, will be terminating upon consummation of the merger. To that end, Pacific Premier requested as part of the transaction that Mr. Perry enter into the confidentiality, non-competition and non-solicitation agreement to protect the banking franchise it would acquire from potential competition by Mr. Perry after the merger. That agreement restricts Mr. Perry's ability to compete with Pacific Premier in the banking business in San Diego County for a three year period in exchange for three annual cash payments. Mr. Perry entering into the confidentiality, non-competition and non-solicitation agreement was one of the considerations with respect to Pacific Premier's decision to proceed with the acquisition of SDTB. See "Interests of Certain SDTB Officers and Directors in the Merger" beginning on page 75 for additional information about Mr. Perry's compensation and the terms of the confidentiality, non-competition and non-solicitation agreement. In determining the aggregate amount of consideration that Pacific Premier would pay to the shareholders of SDTB, Pacific Premier took into consideration the transaction-related expenses that it would incur, including the cash payments and other benefits payable to Mr. Perry following completion of the merger. Neither Pacific Premier nor its financial advisor, D.A. Davidson & Co., or D.A. Davidson, undertook a separate analysis to quantify the impact that these payments to Mr. Perry would have on the merger consideration to be received by the SDTB shareholders. Similar to other contractual obligations of SDTB, Pacific Premier agreed to assume the contractual obligations relating to Mr. Perry's compensation upon completion of the

45


Table of Contents

merger. As part of the merger, Pacific Premier will receive the benefits of insurance policies acquired by SDTB over the years, which are intended to partially fund certain of the compensation obligations owed to Mr. Perry.

        The final terms resulted in a deal valued at 1.19 times SDTB's tangible book value (including its unrealized securities gain of $4.5 million), or 1.45 times Tier 1 Capital (excluding the unrealized gain). In structuring the deal in this manner, SDTB protected its shareholders from the risk associated with the volatility of the unrealized gain in the securities portfolio.

        During discussions with potential strategic partners, SDTB's board of directors was fully aware of all the contractual obligations and other compensation arrangements of SDTB entered into with Mr. Perry over the past 10 years, including those obligations and arrangements that would involve payments in connection with a change in control transaction. SDTB's board of directors also was aware that these types of deal expenses can impact the merger consideration received by shareholders depending on the structure of a transaction and which executives are retained or terminated, similar to any liability or obligation of a target impacting the price in a transaction. Based on discussions that SDTB and KBW had with potential strategic partners, neither SDTB nor KBW is aware that the existence of SDTB's compensation arrangements with Mr. Perry was a significant factor in any of those potential strategic partners' determination whether or not to proceed with a transaction with SDTB. Significant factors discussed or raised in negotiations with potential strategic partners relating to the consideration to be paid for SDTB were (i) the projected future revenue of SDTB, which could be negatively impacted by things such as the projected margin compression, (ii) the re-pricing risk of SDTB's investment securities, (iii) the lack of meaningful demand for credit, and thus loan growth, and (iv) the positive impact of synergies of the combined bank and other cost savings due to the transaction, which could include the termination of some or all of the executive officers of SDTB.

        In light of these facts, on January 28, 2013, following review and approval by SDTB's special mergers and acquisitions committee, SDTB executed a letter of intent with Pacific Premier and agreed to move forward with negotiating a definitive agreement based on the terms outlined in the letter of intent. During February 2013, Pacific Premier and D.A. Davidson, an independent investment banking firm and Pacific Premier's financial advisor, completed their onsite due diligence of SDTB, and SDTB and KBW conducted reverse due diligence on Pacific Premier. During February 2013, SDTB, Pacific Premier and their respective advisors negotiated the terms and conditions of the draft merger agreement.

        On February 28, 2013, Pacific Premier's and the Bank's boards of directors held a special meeting at which management, D.A. Davidson and Patton Boggs LLP, legal counsel to Pacific Premier and the Bank, were represented. Management of Pacific Premier, with the assistance of its financial advisor and legal counsel, reviewed in detail the terms of the merger agreement and the structure of the merger. D.A. Davidson presented its financial analysis of the merger and rendered its oral opinion, which was subsequently confirmed in writing, that as of such date, the merger was fair, from a financial point of view, to the common shareholders of Pacific Premier. Based upon the boards of directors' review and discussion of the merger agreement and the presentation and fairness opinion from D.A. Davidson, the boards of directors of Pacific Premier and the Bank unanimously approved the merger agreement.

        On March 4, 2013, the board of directors of SDTB met with KBW and McKenna Long & Aldridge LLP, legal counsel to SDTB, to review the merger agreement. At the meeting of the board of directors of SDTB, KBW presented its financial analysis of the merger and rendered its oral opinion, which was subsequently confirmed in writing, that as of such date, the merger was fair, from a financial point of view, to the common shareholders of SDTB. SDTB's legal counsel conducted a review and discussion of the terms of the merger agreement. Following these presentations and an extensive discussion amongst the board members of the terms of the merger and payments and obligations that

46


Table of Contents

would be made to Mr. Perry in connection with the merger, the board of directors of SDTB unanimously approved the merger agreement.

        After the closing of the financial markets on March 5, 2013, the merger agreement was executed by the appropriate officers of Pacific Premier, the Bank and SDTB. Before the opening of the financial markets on March 6, 2013, Pacific Premier and SDTB issued a joint press release announcing the execution of the merger agreement and the terms of the proposed merger.


SDTB's Reasons for the Merger

        In reaching its conclusion to proceed with the merger and recommend adoption of the merger agreement to its shareholders, SDTB's board of directors considered information and advice from its financial advisor and its legal counsel. All material factors considered by the SDTB board of directors have been disclosed herein. In approving the merger agreement, the board of directors of SDTB considered a number of factors including the following, without assigning any specific or relative weights to the factors:

        The SDTB board of directors also considered the potential adverse consequences of the proposed merger, including:

Table of Contents

        Based on the reasons stated, SDTB's board of directors believes that the merger is in the best interest of SDTB and its shareholders and unanimously recommends that the SDTB shareholders vote "FOR" approval of the merger agreement.


Pacific Premier's Reasons for the Merger

        As part of Pacific Premier's business strategy, it evaluates opportunities to acquire bank holding companies, banks and other financial institutions. The acquisition of SDTB is consistent with this strategy. Pacific Premier and the Bank entered into the merger agreement with SDTB because, among other things, Pacific Premier believes that the acquisition of SDTB will:


Opinion of SDTB's Financial Advisor

        On November 16, 2012, SDTB engaged KBW to render financial advisory and investment banking services to SDTB. KBW agreed to assist SDTB in assessing the fairness, from a financial point of view, of the aggregate merger consideration in the proposed merger, to the common shareholders of SDTB. SDTB selected KBW because KBW is a nationally recognized investment banking firm with substantial experience in transactions similar to the merger and is familiar with SDTB and its business. As part of its investment banking business, KBW is continually engaged in the valuation of financial services companies and their securities in connection with mergers and acquisitions.

        As part of its engagement, a representative of KBW attended the meeting of the SDTB board of directors held on March 4, 2013, at which the SDTB board of directors evaluated the proposed merger. At this meeting, KBW reviewed the financial aspects of the proposed merger and rendered an opinion that, as of such date, the aggregate merger consideration was fair, from a financial point of view to the holders of SDTB common stock. KBW did not express any view on, and its opinion did not address, the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of SDTB, or any class of such persons in connection with the merger, whether relative to the consideration payable to the SDTB shareholders in connection with the merger or otherwise. The SDTB board approved the merger agreement at this meeting.

        The full text of KBW's written opinion is attached as Appendix B to this proxy statement/prospectus and is incorporated herein by reference. SDTB shareholders are urged to read the opinion in its entirety for a description of the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW. The description of the opinion set forth herein is qualified in its entirety by reference to the full text of such opinion.

Table of Contents

        KBW's opinion speaks only as of the date of the opinion. The opinion is directed to the SDTB board of directors and addresses only the fairness, from a financial point of view, of the aggregate merger consideration to the holders of SDTB common stock. It does not address the underlying business decision to proceed with the merger and does not constitute a recommendation to any SDTB shareholder as to how the shareholder should vote at the SDTB special meeting on the merger or any related matter.

        In rendering its opinion, KBW reviewed, among other things,

        In addition, KBW held discussions with members of senior management of SDTB and Pacific Premier regarding past and current business operations, regulatory relations, financial condition and future prospects of their respective companies, and other matters KBW deemed relevant. KBW also compared certain financial and stock market information for SDTB and Pacific Premier with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the banking industry, and performed other studies and analyses that it considered appropriate.

        In conducting its review and arriving at its opinion, KBW relied upon the accuracy and completeness of all of the financial and other information provided to it or otherwise publicly available. KBW did not independently verify the accuracy or completeness of any such information or assume any responsibility for such verification or accuracy. KBW relied upon the management of SDTB and Pacific Premier as to the reasonableness and achievability of the financial and operating forecasts and projections (and the assumptions and bases therefore) provided to KBW and assumed that such forecasts and projections reflected the best currently available estimates and judgments of such managements and that such forecasts and projections will be realized in the amounts and in the time periods estimated by such managements. KBW assumed, without independent verification, that the aggregate allowance for loan and lease losses for SDTB and the Bank were adequate to cover those losses. KBW did not make or obtain any evaluations or appraisals of the property, assets or liabilities of SDTB, the Bank or Pacific Premier, nor did it examine any individual credit files.

        The projections furnished to KBW and used by it in certain of its analyses were prepared by SDTB's and Pacific Premier's senior management teams. SDTB and Pacific Premier do not publicly disclose internal management projections of the type provided to KBW in connection with its review of the merger. As a result, such projections were not prepared with a view towards public disclosure. The projections were based on numerous variables and assumptions, which are inherently uncertain, including factors related to general economic and competitive conditions. Accordingly, actual results could vary significantly from those set forth in the projections.

        For purposes of rendering its opinion, KBW assumed that, in all respects material to its analyses:

50


Table of Contents

        KBW further assumed that the merger will be accounted for using the purchase method under generally accepted accounting principles, and that the merger will qualify as a tax-free reorganization for United States federal income tax purposes. KBW's opinion is not an expression of an opinion as to the prices at which shares of SDTB common stock or shares of Pacific Premier common stock will trade following the announcement of the merger or the actual value of the shares of common stock of the combined company when issued pursuant to the merger, or the prices at which the shares of common stock of the combined company will trade following the completion of the merger.

        In performing its analyses, KBW made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters, which are beyond the control of KBW, SDTB and Pacific Premier. Any estimates contained in the analyses performed by KBW are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by these analyses. Additionally, estimates of the value of businesses or securities do not purport to be appraisals or to reflect the prices at which such businesses or securities might actually be sold. Accordingly, these analyses and estimates are inherently subject to substantial uncertainty. In addition, the KBW opinion was among several factors taken into consideration by the SDTB board of directors in making its determination to approve the merger agreement and the merger. Consequently, the analyses described below should not be viewed as determinative of the decision of the SDTB board of directors with respect to the fairness of the merger consideration.

        The following is a summary of the material analyses presented by KBW to the SDTB board of directors on March 4, 2013, in connection with its fairness opinion. The summary is not a complete description of the analyses underlying the KBW opinion or the presentation made by KBW to the SDTB board of directors, but summarizes the material analyses performed and presented in connection with such opinion. The preparation of a fairness opinion is a complex analytic process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, KBW did not attribute any particular weight to any analysis or factor that it considered, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. The financial analyses summarized below include information presented in tabular format. Accordingly, KBW believes that its analyses and the summary of its analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on the information presented below in tabular format, without considering all analyses and factors or the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying its analyses and opinion. The tables alone do not constitute a complete description of the financial analyses performed by KBW.

        Summary of Proposal.    Pursuant to the terms of the merger agreement, each share of common stock, no par value, of SDTB not owned by SDTB and Pacific Premier or by any of Pacific Premier's wholly-owned subsidiaries (other than shares owned in a fiduciary capacity or as a result of debts previously contracted) issued and outstanding immediately prior to the merger will be cancelled and retired and converted into the right to receive per share stock consideration or per share cash consideration, subject to adjustments as described in the Agreement. Based on Pacific Premier's 10-day average closing price on March 1, 2013 of $11.96, the aggregate merger consideration was $30.6 million and represented a price of $13.41 per SDTB share to SDTB's common shareholders.

        Selected Companies Analysis.    Using publicly available information, KBW compared the financial performance, financial condition and market performance of SDTB to the following publicly traded institutions headquartered in the Southern California counties of Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, or Ventura with total assets between $100 million and $600 million, and excluded announced merger targets as of March 1, 2013. Companies included in this group were:

1st Century Bancshares, Inc.   Friendly Hills Bank
Bank of Santa Clarita   Manhattan Bancorp
Bank of Southern California, N. A.   Mission Oaks Bancorp
California Republic Bancorp   Mission Valley Bancorp
CalWest Bancorp   NCAL Bancorp

Chino Commercial Bancorp   Orange County Business Bank
Commerce National Bank   Plaza Bank
CommerceWest Bank   Premier Service Bank
Community Valley Bank   Santa Clara Valley Bank, N.A.
Coronado First Bank   Seacoast Commerce Bank
County Commerce Bank   Security California Bancorp

        Using publicly available information, KBW compared the financial performance, financial condition, and market performance of Pacific Premier to the following institutions traded on the New York Stock Exchange or Nasdaq Stock Market headquartered in California with total assets between $1.0 billion and $2.0 billion and excluded announced merger targets as of March 1, 2013. Companies included in this group were:

Bank of Marin Bancorp   Heritage Oaks Bancorp
Bridge Capital Holdings   Pacific Mercantile Bancorp
CU Bancorp   Preferred Bank
First PacTrust Bancorp, Inc.   Sierra Bancorp
Heritage Commerce Corp    

        To perform this analysis, KBW used financial information as of the most recent three month period available (ended either December 31, 2012 or September 30, 2012) and market price information was as of March 1, 2013. Earnings estimates for 2013 and 2014 were taken from a nationally recognized earnings estimate consolidator for selected companies. Certain financial data prepared by KBW, and as referenced in the tables presented below, may not correspond to the data presented in SDTB's and Pacific Premier's historical financial statements as a result of the different periods, assumptions and methods used by KBW to compute the financial data presented.

The Western Region, as defined by KBW, includes the following 13 states: Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming.

        No company or transaction used as a comparison in the above analysis is identical to SDTB, Pacific Premier or the merger. Accordingly, an analysis of these results is not mathematical. Rather, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies.

        Financial Impact Analysis.    KBW performed pro forma merger analyses that combined projected income statement and balance sheet information of SDTB and Pacific Premier. 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 Pacific Premier. In the course of this analysis, KBW used 2014 earnings estimates for Pacific Premier from a nationally recognized earnings estimate consolidator and for SDTB from SDTB management. This analysis indicated that the merger is expected to be accretive to Pacific Premier's estimated earnings per share in 2014. The analysis also indicated that the merger is expected to be dilutive to book value per share and dilutive to tangible book value per share for Pacific Premier and that Pacific Premier would maintain well capitalized capital ratios. For all of the above analyses, the actual results achieved by Pacific Premier following the merger will vary from the projected results, and the variations may be material.

        Discounted Cash Flow Analysis.    KBW performed a discounted cash flow analysis to estimate a range of the present values of after-tax cash flows that SDTB could provide to equity holders through 2018 on a stand-alone basis. In performing this analysis, KBW used earnings estimates for 2013 to 2018, from SDTB management, and assumed discount rates ranging from 12.0% to 17.0%. The range of values was determined by adding (1) the present value of projected cash flows to SDTB shareholders from 2013 to 2017 and (2) the present value of the terminal value of SDTB's common stock. In determining cash flows available to shareholders, KBW assumed balance sheet growth per SDTB management and assumed that SDTB would maintain a tangible common equity / tangible asset ratio

of 8.00% and would retain sufficient earnings to maintain that level. Any earnings in excess of what would need to be retained represented dividendable cash flows for SDTB. In calculating the terminal value of SDTB, KBW applied multiples ranging from 10.0 times to 14.0 times 2018 forecasted earnings. This resulted in a range of values of SDTB from $9.56 to $13.98 per share. The discounted cash flow present value analysis is a widely used valuation methodology that relies on numerous assumptions, including asset and earnings growth rates, terminal values and discount rates. The analysis did not purport to be indicative of the actual values or expected values of SDTB.

        The SDTB board of directors retained KBW as financial adviser to SDTB regarding the merger. As part of its investment banking business, KBW is continually engaged in the valuation of bank and bank holding company securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for other purposes. As specialists in the securities of banking companies, KBW has experience in, and knowledge of, the valuation of banking enterprises. In the ordinary course of its business as a broker-dealer, KBW may, from time to time, purchase securities from, and sell securities to, SDTB and Pacific Premier. As a market maker in securities, KBW may from time to time have a long or short position in, and buy or sell, debt or equity securities of SDTB and Pacific Premier for KBW's own account and for the accounts of its customers. To the extent KBW held any such positions, it was disclosed to SDTB.

        SDTB and KBW entered into an agreement relating to the services to be provided by KBW in connection with the merger. SDTB paid KBW a cash fee of $100,000 concurrently with the rendering of the fairness opinion related to the merger. In addition, SDTB agreed to pay KBW at the time of closing of the merger a cash fee equal to 1.0% of aggregate deal value. During the past two years, KBW has provided investment banking and financial advisory services to SDTB, but has not received compensation for such services. KBW has not provided investment banking or financial advisory services to, and has not received compensation from, Pacific Premier during the past two years. KBW may in the future provide investment banking and financial advisory services to Pacific Premier and receive compensation for such services.


The Merger Consideration

        General.    At the effective time of the merger, each share of SDTB common stock outstanding immediately before the effective time of the merger, except as provided below, will, by virtue of the merger and without any action on the part of a SDTB shareholder, be converted into the right to receive the per share cash consideration or the per share stock consideration, or a combination of both, which is described below. The aggregate consideration to be paid to SDTB shareholders in the merger is referred to as the merger consideration. 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 82.

        The merger consideration may be paid in cash in an amount equal to $13.41 per share of SDTB common stock, which is referred to as the per share cash consideration, 1.114 shares of Pacific Premier common stock, which is referred to as the per share stock consideration, or a combination of cash and Pacific Premier common stock. The cash portion of the merger consideration and the stock portion of the merger consideration are both subject to possible adjustment prior to the closing of the merger, each of which is described in more detail below. SDTB shareholders will have the opportunity to elect the form of consideration to be received for all shares of SDTB common stock held by them, subject to the allocation procedures set forth in the merger agreement which are intended to ensure that 50% of the aggregate value of the merger consideration is paid in the form of shares of Pacific Premier common stock, and 50% of the aggregate merger consideration is paid in cash. Cash will be paid in lieu of any fractional share interest. See "—Elections," "—Election Procedures" and "—Allocation Procedures" beginning on page 60.

Table of Contents

        The form of the consideration ultimately received by you will depend upon your election and the allocation and pro ration procedures described below. Accordingly, no guarantee can be given that your election choice will be fully honored.

        Per Share Cash Consideration and Possible Adjustment.    The cash portion of the merger consideration will be subject to downward adjustment if SDTB's aggregate transaction-related expenses exceed $3.0 million, on an after-tax equivalent basis, with any excess amount reducing the per share cash consideration by the quotient of (i) such excess amount divided by (ii) the total number of shares of issued and outstanding SDTB common stock. Pursuant to the terms of the merger agreement, SDTB's transaction-related expenses consist of certain fixed amounts, such as SDTB's accounting and advisory fees and expenses associated with the accrual of benefits, change in control and other contractual payments and non-competition payments payable to SDTB's Chairman, Chief Executive Officer and President, Michael E. Perry, which are estimated to amount to $2.7 million in the aggregate on an after-tax basis, of which $2.5 million is in connection with payments to Mr. Perry as well as certain amounts that are not fixed, such as SDTB's legal fees and premiums for extended directors and officers liability insurance to the extent premiums exceed 200% of current SDTB premiums. As of May 9, 2013, which is the latest practicable date before the filing of this proxy statement/prospectus, the aggregate amount of estimated fixed transaction-related expenses plus the variable transaction-related expenses actually incurred by SDTB, on an after-tax equivalent basis, totaled approximately $2.8 million. Although no assurances can be made as to the final amount of SDTB's transaction-related expenses as of the closing date of the merger, SDTB does not anticipate that its transaction-related expenses, on an after-tax basis, will exceed $3.0 million based on currently available information. The cash portion of the merger consideration is not subject to an upward adjustment if SDTB's aggregate transaction-related expenses are less than $3.0 million, on an after-tax equivalent basis. Because the cash portion of the merger consideration is subject to a downward adjustment, the amount of cash consideration to be received will not be known at the time SDTB shareholders elect the form of merger consideration they wish to receive or when SDTB shareholders vote on the merger agreement. To the extent that no downward adjustment to the per share cash consideration occurs and based on the allocation procedures which will provide for 50% of the 2,151,395 shares of SDTB common stock outstanding shall elect to receive the per share cash consideration, the cash portion of the merger consideration would be approximately $14,425,103, or $13.41 for each share of SDTB common stock.

        Per Share Stock Consideration and Possible Adjustment.    The per share stock consideration is subject to (i) downward adjustment if the average closing price of Pacific Premier's common stock during the 10 trading day period ending on the fifth business day prior to the effective time of the merger, which is referred to as the PPBI Average Share Price, is greater than $13.240 and (ii) upward adjustment if the PPBI Average Share Price is less than $10.832. To the extent the PPBI Average Share Price is greater than $13.240, the per share stock consideration will adjust down to a number of shares of Pacific Premier common stock equal to (X) $14.751 divided by (Y) the PPBI Average Share Price, rounded to the nearest thousandth. To the extent the PPBI Average Share Price is less than or equal to $10.832, the per share stock consideration will adjust up to a number of shares of Pacific Premier common stock equal to (A) $12.069 divided by (B) the PPBI Average Share Price, rounded to the nearest thousandth. Any proposed adjustment in the per share stock consideration is subject to the limitation that the number of shares of Pacific Premier common stock issued at the closing of the merger may not exceed 19.9% of the outstanding shares of Pacific Premier common stock, which is referred to in this proxy statement/prospectus as the stock limit. If the stock limit is reached, no other adjustment will be made to any other merger consideration to be paid to SDTB shareholders, and the aggregate number of shares of Pacific Premier common stock to be issued will be equal to 19.9% of the outstanding shares of Pacific Premier common stock immediately prior to the closing date of the merger.

Table of Contents

        Upon completion of the merger, based on the allocation procedures which provide for 50% of the 2,151,395 shares of SDTB common stock outstanding as of the date of this proxy statement/prospectus receiving the per share stock consideration, SDTB shareholders are expected to receive 1,198,327 shares of Pacific Premier common stock. Following the completion of the merger, and based on 15,437,531 shares of Pacific Premier common stock outstanding as of May 9, 2013, the former SDTB shareholders will own approximately 7.20% of the outstanding shares of Pacific Premier common stock and the current shareholders of Pacific Premier will own the remaining approximately 92.80% of the outstanding shares of common stock.

        Shares of SDTB common stock held by SDTB shareholders who have elected to exercise their dissenters' rights will not be converted into the right to receive the merger consideration upon consummation of the merger. The dissenters' rights available to SDTB shareholders are described more fully in this proxy statement/prospectus under "—Dissenters' Rights" beginning on page 88.


Merger Consideration Example

        As discussed above, the merger consideration to be received by SDTB shareholders will be subject to change and will likely fluctuate prior to the closing of the merger, based on the PPBI Average Share Price. The following table illustrates what the exchange ratio, the related per share stock consideration, the per share cash consideration and the aggregate stock, cash and merger consideration values would be depending upon changes to the PPBI Average Share Price, ranging from 20% above $12.036, which was the PPBI Average Share Price as of March 5, 2013, to 20% below $12.036. The following table assumes there are 2,151,395 shares of SDTB common stock outstanding as of the closing date, and that the per share cash consideration is $13.41. The table also assumes that the aggregate merger consideration paid consists of 50% cash and 50% shares of Pacific Premier common stock, and therefore, 1,075,698 shares of SDTB common stock will be exchanged for the per share stock consideration. As described below under "—Allocation Procedures" beginning on page 61, regardless of whether an SDTB shareholder makes an all-cash election or an all-stock election, that SDTB shareholder may nevertheless receive a mix of cash and shares of Pacific Premier common stock as merger consideration. The table does not reflect the fact that cash will be paid instead of fractional shares.

Table of Contents

        The examples above are illustrative only and are based on the assumptions indicated. The value of the merger consideration that an SDTB shareholder actually receives will be based on the actual PPBI Average Share Price calculated prior to completion of the merger, as described below, which may be outside the range of the amounts set forth in the examples above. As a result, the examples above may not show the actual value of the merger consideration that SDTB shareholders will be entitled to receive upon closing of the merger.

        Fractional Shares.    No fractional shares of Pacific Premier common stock will be issued, and in lieu thereof, each holder of SDTB 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 $13.41, which amount reflects the per share cash consideration, 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.

        Elections.    No later than the date that this proxy statement/prospectus is mailed to holders of record of SDTB common stock, American Stock Transfer & Trust Company, the exchange agent, will mail to each holder of record of SDTB common stock as of the record date for the special meeting an election form and transmittal materials for use in making the election and effecting the surrender of certificates representing shares of SDTB common stock in exchange for the merger consideration allocated to them. The election form will permit each SDTB shareholder:

        Shares of SDTB common stock for which an election has been made to receive shares of Pacific Premier common stock (including pursuant to a mixed election) are referred to as "stock election shares." Shares of SDTB common stock for which an election has been made to receive the cash consideration (including pursuant to a mixed election) are referred to as "cash election shares." Shares of SDTB common stock for which no election has been made are referred to as "no-election shares."

        If an SDTB shareholder either (i) does not submit a properly completed election form in a timely fashion or (ii) revokes their election form prior to the deadline for the submission of the election form and does not resubmit a properly completed election form by the election form deadline, the shares of SDTB common stock held by that SDTB shareholder will be designated no-election shares.

        Election Procedures.    To be effective, a properly completed and executed election form must be submitted to the exchange agent on or before 5:00 p.m., Pacific Time, on June 21, 2013.

        Even if an SDTB shareholder has no preference as to the form of merger consideration, it is suggested that they return their election form and transmittal materials, together with their stock certificate(s), by the election deadline indicating that they have no preference, so that they may receive the merger consideration allocable to them promptly following completion of the exchange procedures after the merger is consummated.

        If an SDTB shareholder's shares of SDTB common stock are held in street name by a broker, only that broker or other nominee can make an election with respect to the consideration to be received by the SDTB shareholder in exchange for their shares of SDTB common stock. A broker or other

nominee, however, will not be able to make the election without instructions from the SDTB shareholder. SDTB shareholders should instruct their broker or other nominee on which election to make, following the directions the broker or other nominee provides. If an SDTB shareholder fails to instruct their broker or other nominee on which election to make, the SDTB shareholder will be treated as if they did not make an election with respect to the consideration to be received by them in exchange for their shares of SDTB common stock. Such shares will be treated as no-election shares and will be subject to the allocations procedures described in this proxy statement/prospectus.

        SDTB shareholders should not return their SDTB stock certificates with the enclosed proxy, and stock certificates should not be forwarded to Pacific Premier, SDTB or any other party until SDTB shareholders have received the election form and related transmittal materials, which will be sent to them concurrently with this proxy statement/prospectus under separate cover.

        If an SDTB shareholder has a particular preference as to the form of consideration to be received for their shares of SDTB common stock, they should make an election because shares as to which an election has been made will be given priority in allocating such consideration over shares as to which no election was made. Neither the SDTB board of directors nor its financial advisor makes any recommendation as to whether SDTB shareholders should elect to receive the cash consideration, the stock consideration or a combination of stock and cash in the merger. SDTB shareholders must make their own decision with respect to such election, bearing in mind the tax consequences of the election they choose. See "—Material Federal Income Tax Consequences" beginning on page 82.

        Allocation Procedures.    An SDTB shareholder's ability to receive all cash or all shares of Pacific Premier common stock in exchange for their shares of SDTB common stock in the merger is subject to allocation procedures that are designed to ensure that 50% of the aggregate value of the merger consideration is paid in the form of shares of Pacific Premier common stock, and 50% of the aggregate merger consideration is paid in cash.

        It is unlikely that elections will be made in the exact proportions provided for in the merger agreement. As a result, the merger agreement provides for procedures to be followed if SDTB shareholders in the aggregate elect to receive more or less of the Pacific Premier common stock than Pacific Premier has agreed to issue. These procedures are summarized below.

        Pursuant to the terms of the merger agreement, the exchange agent will effect the allocation of the merger consideration among holders of shares of SDTB common stock as follows:

61


Table of Contents

        Shares of SDTB common stock held by SDTB shareholders who have perfected their dissenters' rights, as described more fully in this proxy statement/prospectus under "—Dissenters' Rights" beginning on page 88, will be treated as cash election shares for purposes of the allocation procedures described above.

        In addition, if at the time of the closing of the merger, the aggregate value of the shares of Pacific Premier common stock to be exchanged for shares of SDTB common stock is less than 45% of the sum of (i) the aggregate merger consideration and (ii) the aggregate cash consideration paid by Pacific Premier to the holders of options to purchase shares of SDTB's common stock, which is described below, then Pacific Premier will cause a minimum number of no-election shares and, to the extent necessary, a minimum number of cash election shares, to be converted into stock election shares so that the aggregate value of the shares of Pacific Premier common stock exchanged for shares of SDTB common stock constitutes 45% of the sum of (i) the aggregate merger consideration and (ii) the aggregate cash consideration paid by Pacific Premier to the holders of options to purchase shares of SDTB's common stock.


SDTB Options

        Pursuant to the terms of the merger agreement, at least one hundred (100) days prior to the anticipated closing date of the merger, SDTB's board of directors is required to declare that each option to purchase shares of SDTB's common stock, referred to in this proxy statement/prospectus as an SDTB option, that is then outstanding, but that is not then exercisable, shall become fully vested and exercisable for a period of three (3) months ending immediately before the anticipated closing date of the merger. Following this acceleration declaration by the SDTB board of directors, and at least ninety (90) days prior to the anticipate closing date of the merger, SDTB is required to deliver a written notification to each holder of SDTB options, informing him or her of the declaration. The vesting and exercise will be effective on the closing date of the merger.

        Each SDTB option, vested or unvested, that remains outstanding as of the closing of the merger will be cancelled in accordance with the San Diego Trust Bank Second Amended and Restated 2003 Stock Plan, or the SDTB Stock Option Plan, upon the closing of the merger, and each holder of such SDTB option will be entitled to receive from Pacific Premier, as soon as reasonably practicable after the effective time of the merger, but in no event later than three (3) days after such effective time, a single lump sum cash payment equal to the product of (i) the number of shares of SDTB common stock subject to such SDTB option immediately prior to the closing of the merger, and (ii) the excess, if any, of the per share cash consideration over the exercise price per share of such SDTB option, less any applicable taxes required to be withheld with respect to such payment. If the exercise price per share of any such SDTB option is equal to or greater than the per share cash consideration, such SDTB option will be canceled without any cash payment being made in respect thereof.

        At least thirty (30) days prior to the expected closing date of the merger, SDTB is required to send a request to all holders of all of the then-outstanding SDTB options requesting that they return a written acknowledgment with regard to the cancellation of his or her SDTB options and the payment therefor in accordance with the terms of the merger agreement. SDTB shall use its reasonable best efforts to obtain the written acknowledgment of each holder of a then-outstanding SDTB option with regard to the cancellation of such SDTB option and the payment therefor in accordance with the terms of the merger agreement.

        Subject to the foregoing, the SDTB Stock Option Plan and all SDTB options issued thereunder will terminate at the effective time of the merger.

Procedures for Exchanging SDTB Common Stock Certificates

        No later than the date that this proxy statement/prospectus is mailed to holders of record of SDTB common stock, American Stock Transfer & Trust Company, the exchange agent, will mail to each holder of record of SDTB common stock as of the record date for the special meeting an election form and transmittal materials for use in making the election and effecting the surrender of certificates representing shares of SDTB common stock in exchange for the merger consideration allocated to them. Upon surrender of a stock certificate of SDTB common stock for exchange and cancellation to the exchange agent, together with a duly executed election form and transmittal letter, the holder of such certificate will be entitled to receive the merger consideration allocated to them and the certificate for SDTB common stock so surrendered will be canceled. No interest will be paid or accrued on any cash constituting merger consideration.

        For those SDTB shareholders who surrender their stock certificates and letter of transmittal at least five (5) business days prior to the closing of the merger, Pacific Premier will use its commercially reasonable efforts to cause the exchange agent to deliver the merger consideration payable to them as a result of the merger within one (1) business day following the closing. For those SDTB shareholders who surrender their stock certificates and complete the letter of transmittal at any time after five (5) business days prior to the closing of the merger, Pacific Premier will use commercially reasonable efforts to cause the exchange agent to promptly deliver the merger consideration payable to them as a result of the merger as soon as practicable, but in no event later than five (5) business days following receipt of their stock certificates and completed letter of transmittal.

        No stock certificates representing fractional shares of Pacific Premier common stock will be issued upon the surrender for exchange of SDTB stock certificates. In lieu of the issuance of any such fractional share, Pacific Premier will pay to each former shareholder of SDTB who otherwise would be entitled to receive a fractional share of Pacific Premier common stock an amount in cash, without interest, determined by multiplying such fractional interest by $13.41, which amount reflects the per share cash consideration, rounded to the nearest whole cent.

        Any SDTB 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 SDTB stock certificates. Only then will the SDTB 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 SDTB common stock issued and outstanding immediately prior to the completion of the merger will be allowed. SDTB 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 SDTB stock certificate is registered if a SDTB shareholder presents the exchange agent with all documents required to show and effect the unrecorded transfer of ownership of the shares of SDTB common stock formerly represented by such SDTB stock certificate, and that the SDTB shareholder has paid any applicable stock transfer taxes.

        If an SDTB shareholder has lost his or her SDTB stock certificate, or the SDTB stock certificate has been lost, stolen or destroyed, the SDTB 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:

        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:

64


Table of Contents

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

        Under the terms of the merger agreement, a material adverse effect on either Pacific Premier or SDTB is defined to mean any effect that, taken individually or together with any other effect, (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 SDTB, as the case may be, or (ii) would materially impair the ability of Pacific Premier and its subsidiaries taken as a whole or SDTB, 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:

65


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 SDTB on the other hand, as measured relative to similarly situated companies in the banking industry.


Bank Regulatory Approvals

        California Department of Financial Institutions; Board of Governors of the Federal Reserve System. The prior approval of each of the CA DFI and the Federal Reserve is required under the California Financial Code and the federal Bank Merger Act, respectively, to consummate the merger. Pacific Premier and SDTB have received the approval from each of these banking regulators. 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, SDTB shareholders. Regulatory approval does not constitute an endorsement or recommendation of the proposed merger.

        In reviewing the merger, the CA DFI and the Federal Reserve take competitive considerations into account, as well as capital adequacy, quality of management and earnings prospects. The regulators also take into account the record of performance of the Bank in meeting the credit needs of the communities that it serves and the Bank's regulatory rating under the Community Reinvestment Act, or CRA. The Bank and SDTB both received a "satisfactory" performance rating in their most recent CRA evaluations. In considering the merger, the California Financial Code also requires the CA DFI 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 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 SDTB do not know of any reason that the 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 SDTB 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 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.

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 proxy statement/prospectus, are briefly described below.

        Pending consummation of the merger, SDTB may not, among other things, take the following actions without the prior written consent of Pacific Premier:

67


Table of Contents

68


Table of Contents

        In connection with the application filed by Pacific Premier with the Federal Reserve for approval of the merger, Pacific Premier entered into a commitment with the Federal Reserve whereby it agreed to limit its right to approve SDTB loans, guarantees and securitizations during the period between the signing of the merger agreement through the closing of the merger to amounts of $2.0 million or more, instead of the $250,000 threshold provided for in the merger agreement, as described in the nineteenth bullet point under "—Business Pending the Merger."

        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 SDTB:


Board of Directors' Covenant to Recommend the Merger Agreement

        Pursuant to the merger agreement, the SDTB board of directors is required to recommend that SDTB shareholders approve the merger agreement at all times prior to and during the meeting of SDTB shareholders at which the merger agreement is to be considered by them. The SDTB 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 meeting of its shareholders inconsistent with such recommendation, except as described below. Regardless of whether the SDTB board of directors changes its recommendation, the merger agreement must be submitted to the SDTB shareholders at the meeting of SDTB shareholders for the purpose of approving the merger agreement and any other matters required to be approved by SDTB's shareholders for consummation of the transaction. SDTB may not submit to the vote of its shareholders any acquisition proposal other than the merger.

Table of Contents

        The SDTB board of directors is permitted to change its recommendation if SDTB has complied with the merger agreement and the SDTB board of directors, based on the advice of its outside counsel, 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 SDTB board of directors intends to change its recommendation following an acquisition proposal, as described in "—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. SDTB also must notify Pacific Premier at least five 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 a copy of the relevant proposed transaction agreements with the party making the superior proposal and all other material documents. Prior to changing its recommendation, SDTB 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 business days to the extent Pacific Premier desires to negotiate to make the adjustments in the terms and conditions of the merger agreement so that the other acquisition proposal ceases to constitute a superior proposal.


No Solicitation

        The merger agreement provides that SDTB 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 SDTB; (ii) direct or indirect acquisition or purchase of any class of equity securities representing 10% or more of the voting power of SDTB; (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 SDTB; or (iv) merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving SDTB, other than the transactions contemplated by the merger agreement.

        From the date of the merger agreement through the effective time of the merger, SDTB 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.

        However, prior to the date of the special meeting of the SDTB shareholders, if the SDTB board of directors determines in good faith, after consulting with its outside legal and financial advisors, that the

70


Table of Contents

failure to do so would breach, or would reasonably be expected to result in a breach of, its fiduciary duties under applicable law, SDTB may, in response to a bona fide, written acquisition proposal not solicited in violation of the merger agreement that the SDTB board of directors determines in good faith constitutes a superior proposal, subject to providing 48 hours 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 SDTB common stock then outstanding or all or substantially all of SDTB's consolidated assets, that the SDTB 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 SDTB's financial advisor, which will be a nationally 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 SDTB board of directors, is reasonably likely to be obtained by the third party.

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

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

        Pacific Premier, the Bank and SDTB have agreed that irreparable damage would occur in the event SDTB or any of its 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 SDTB 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 warranties, reference is made to Article V of the merger agreement included as Appendix A to this proxy statement/prospectus. Such representations and warranties generally must remain accurate

71


Table of Contents

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 64.

        The merger agreement contains representations and warranties that Pacific Premier and SDTB 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 SDTB 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 attached merger agreement.

        Accordingly, you should not 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 public disclosures.


Effective Time of the Merger

        Pursuant to the terms and conditions set forth in the merger agreement, SDTB will be acquired by Pacific Premier whereby SDTB will merge with and into the Bank, with the Bank as the surviving institution. The merger will become effective upon the acceptance of the articles of merger to be filed with the CA DFI and the certification and acceptance by the Secretary of State of the State of California in accordance with the provisions of applicable California law.


Amendment of the Merger Agreement

        Prior to the Effective Time, any provision of the merger agreement may be amended or modified at any time, by an agreement in writing among the parties to the merger agreement, except that after the approval of the principal terms of the merger agreement by the SDTB shareholders, no amendment shall be made which by law requires further approval by the shareholders of SDTB without obtaining such approval. The merger agreement provides that, by approving the principal terms of the merger agreement, SDTB shareholders will be deemed to have approved any amendment to the September 30, 2013 termination date described below.


Termination of the Merger Agreement

        The merger agreement may be terminated:

72


Table of Contents


Termination Fee

        The merger agreement provides that SDTB must pay Pacific Premier a $1.75 million termination fee under the circumstances and in the manner described below:

73


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 SDTB fails to timely pay the termination fee to Pacific Premier, SDTB will be obligated to pay the costs and expenses incurred by Pacific Premier to collect such payment, 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 SDTB will be entitled to participate in the Pacific Premier and the 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 SDTB until such employees are permitted to participate in the Pacific Premier benefit plans. Pacific Premier and the Bank, however, shall not be under any obligation to make any grants to any former employee of SDTB under any discretionary equity compensation plan of Pacific 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 SDTB to the same extent as such service was credited for such purpose by SDTB, 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 SDTB benefit plan in accordance with their terms at any time.

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

74


Table of Contents

        At and following the effective time of the merger, Pacific Premier shall honor and the Bank 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 SDTB and current and former directors of SDTB existing as of the effective date of the merger, as well as all bonus deferred compensation or other existing plans and policies of SDTB that were disclosed to Pacific Premier.

        Those employees of SDTB who are not offered employment by Pacific Premier or the 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 (which will be negotiated between Pacific Premier and SDTB) within 30 days of the closing of the merger will be entitled to receive a single lump sum payment of severance equal to two weeks of salary for each year of service (with a prorated amount of payment for partial years), up to a maximum of 13 weeks. These payments will be made by Pacific Premier on the date the termination and release agreement that is executed by an employee becomes effective, which date will be in the sole discretion of Pacific Premier. If SDTB also has a severance pay plan, then any amounts paid pursuant to that plan will reduce the amount that the employee will receive as severance from Pacific Premier and in no event will there be any duplication of severance pay.


Interests of Certain SDTB Officers and Directors in the Merger

        When SDTB shareholders are considering the recommendation of SDTB's board of directors with respect to approving the merger agreement, SDTB shareholders should be aware that SDTB directors and officers have interests in the merger as individuals that are in addition to, or different from, their interests as shareholders of SDTB. The SDTB 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 SDTB beneficially owned and had the power to vote as of May 9, 2013, a total of 518,866 shares of SDTB common stock, representing approximately 24.1% of the outstanding shares of SDTB common stock. See "Certain Beneficial Ownership of SDTB Common Stock" beginning on page 115. 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 executive officers and directors of SDTB who own shares of SDTB common stock. See "—Shareholder Agreements" beginning on page 87. Each of these persons will receive the same merger consideration for their shares of SDTB common stock as the other SDTB shareholders.

        Stock Options.    The merger agreement provides that at the effective time of the merger, each option to purchase shares of SDTB common stock granted under the SDTB Stock Option Plan which is outstanding, vested or unvested, immediately prior thereto will be canceled in exchange for the right to receive a lump sum cash payment equal to the product of (1) the number of shares of SDTB common stock subject to such holder's stock option and (2) the excess, if any, of the per share cash consideration and the exercise price per share of such stock option. Pursuant to the SDTB Stock Option Plan, all outstanding stock options that are currently not vested will be vested immediately prior to the effective time of the merger and option holders will receive a lump sum cash payment for their options.

75


Table of Contents

        As of the date of this proxy statement/prospectus, directors and executive officers of SDTB held options to purchase 111,222.49 and 239,230.89 shares of SDTB common stock, respectively, at prices ranging from $6.2840 to $15.7100 per share. The aggregate amount to be paid to SDTB's directors and officers for stock options held by them is approximately $1,450,874.

        Employment Agreement.    In connection with the signing of the merger agreement, the Bank entered into an employment agreement with James T. Reschan, who currently serves as SDTB's Senior Executive Vice President and Chief Operating Officer. Mr. Reschan's current employment agreement with SDTB will be terminated, and his employment agreement with the Bank will become effective, upon consummation of the Merger. A copy of the employment agreement entered into with Mr. Reschan is attached as Annex D to the merger agreement, which is attached to this proxy statement/prospectus as Appendix A.

        Mr. Reschan's employment agreement with the Bank provides for Mr. Reschan to be appointed as the Bank's Senior Vice President—Regional Manager for San Diego County and will be responsible for sales generation and branch operations for the Bank in San Diego County. The employment agreement provides for a term of employment ending upon the earlier to occur of (i) three (3) years, commencing on the closing date of the merger, unless such term is extended, and (ii) the termination of the executive's employment with the Bank. Mr. Reschan will receive an annual base salary of $200,000, and Mr. Reschan will be eligible for bonuses and will be entitled to participate in any pension, retirement or other benefit plan or program given to employees and executives of the Bank, to the extent commensurate with his duties and responsibilities as fixed by the board of directors of the Bank or the President of the Bank. Mr. Reschan is entitled to a monthly automobile allowance.

        In the event that Mr. Reschan's employment with the Bank is terminated (i) by the Bank other than for cause or death or disability, and his termination occurs within two (2) years following a change in control, or (ii) by Mr. Reschan due to a material breach of his employment agreement or for good reason, then Mr. Reschan will be entitled to receive a lump sum cash severance amount equal to his base salary plus his incentive bonus for the previous year as in effect immediately prior to the date of termination, less taxes and other required withholdings. In the event that Mr. Reschan's employment with the Bank is terminated by the Bank other than for cause or death or disability, and his termination does not occur in connection with a change in control or within two (2) years after a change in control, then Mr. Reschan will be entitled to receive a lump sum cash severance amount equal to his base salary. In each circumstance described in the prior two sentences, Mr. Reschan will be entitled to receive for a period ending at the earlier of (i) the first anniversary of the date of termination or (ii) the date of his full-time employment by another employer, at no cost to Mr. Reschan, the continued participation in all group insurance, life insurance, health and accident, disability and other employee benefit plans, programs and arrangements in which Mr. Reschan was entitled to participate immediately prior to the date of termination, other than any stock option or other stock compensation plans or bonus plans of Pacific Premier or the Bank. If Mr. Reschan's participation in any such plan, program or arrangement is barred, the Bank will arrange to provide him with benefits substantially similar to those he was entitled to receive under such plans, programs and arrangements.

        In the event that Mr. Reschan's employment is terminated as a result of disability or death during the term of the employment agreement, Mr. Reschan, or his estate in the event of death, will receive his existing base salary as in effect as of the date of termination or death, multiplied by one (1) year. If Mr. Reschan is terminated for cause, or he terminates his employment other than for disability or good reason, then he will have no right to compensation or other benefits for any period after the date of termination other than for base salary accrued through the date of termination.

76


Table of Contents

        In addition, Mr. Reschan's employment agreement includes covenants whereby Mr. Reschan agrees not to, for a period of one (1) year following termination of employment with the Bank:

        Confidentiality, Non-Competition and Non-Solicitation Agreement.    In connection with the signing of the merger agreement, the Bank entered into a confidentiality, non-competition and non-solicitation agreement with Michael E. Perry, who currently serves as SDTB's Chairman, President and Chief Executive Officer. The confidentiality, non-competition and non-solicitation agreement with Mr. Perry will become effective upon consummation of the merger. A copy of the confidentiality, non-competition and non-solicitation agreement is attached as Annex E to the merger agreement, which is attached to this proxy statement/prospectus as Appendix A.

        Pursuant to his confidentiality, non-competition and non-solicitation agreement, Mr. Perry agrees to maintain the confidentiality of specified confidential and proprietary information, and he agrees that, for a period of three (3) years following the closing of the merger, he will not:

        In consideration for his non-competition and non-solicitation covenants, Mr. Perry will receive a fee from the Bank payable in three (3) equal annual installments of $375,000, on a pre-tax basis, with the first installment payable on the closing of the merger and the remaining two (2) installments payable on the first and second anniversaries of the closing of the merger. The form of confidentiality, non-competition and non-solicitation agreement is included as Annex E to the merger agreement.

Table of Contents

        SDTB's Compensation and Retirement Arrangements with Mr. Perry.    SDTB has four compensation arrangements with Mr. Perry that will be affected as a result of his employment being terminated in connection with the merger. Pacific Premier has agreed to assume all of the obligations under these arrangements in connection with the merger.

        The amounts set forth in the discussion that follows are approximate and based upon the assumption that the merger is completed on June 30, 2013. An earlier or later closing date for the merger would cause certain of the amounts to change, although any such changes are not expected to be material. The amounts set forth in the discussion that follows are also on a pre-tax basis and therefore cannot be directly used for purposes of calculating transaction related expenses, which are considered on an after-tax basis.

        Merger-Related Payments Under Employment Agreement.    Mr. Perry currently serves SDTB under the terms of an employment agreement that would, but for the merger, terminate on December 31, 2015.

        As a result of his termination in connection with the merger, Mr. Perry is entitled to a lump sum "change in control" payment of $628,403, plus interest, that will be paid to him six months after the merger is completed. This amount is equal to approximately one times Mr. Perry's average taxable compensation from 2008 through 2012.

        In addition, Mr. Perry will receive liquidated damages designed to compensate him for the loss of salary and bonus caused by his termination. He will receive 18 months of his base salary, which is currently $275,000 per annum. The first six months of payments, plus interest, would be delayed until six months following completion of the merger. In addition, assuming the merger is completed in 2013, he would receive a full-year bonus for 2013 expected to equal $250,000, payable in the first 120 days of 2014, and a half-year bonus of $125,000, payable in the first 120 days of 2015.

        Certain of Mr. Perry's benefits are continued after the merger under his employment agreement as well. His medical and life insurance, auto allowance ($18,000 per annum), home security ($528 per annum), and make-up for lost employer contribution to 401(k) are continued for eighteen months. Certain memberships ($1,704 per annum) and office space (or in-kind payment to obtain similar office space) are provided for three years.

        Assumption of Obligations of 2009 Supplemental Executive Retirement Plan.    Pursuant to the merger agreement, Pacific Premier shall assume SDTB's obligations under Mr. Perry's 2009 Supplemental Executive Retirement Plan. The 2009 Supplemental Executive Retirement Plan provides, among other things, that should he retire on or after age 65, he would be entitled to receive monthly payments for ten years after his retirement. Under the plan, he would be entitled to a lesser amount if he retires between age 56 and 65. However, as a result of his termination in connection with the merger, under the plan, Mr. Perry will begin to receive payments of $277,879 annually, which are payable monthly beginning on the date of his termination for ten years. The initial six months of payments will be delayed until the date six months after the completion of the merger and will bear interest during that delay.

        In addition to Mr. Perry's 2009 Supplemental Executive Retirement Plan, the SDTB board of directors adopted a Supplement Executive Retirement Plan for Mr. Perry in 2007. Mr. Perry is not fully vested in his 2007 Supplement Executive Retirement Plan. As a result, Mr. Perry will not receive any payments under the 2007 Supplement Executive Retirement Plan and will forfeit any benefits he might otherwise receive from it as a result of his termination of employment in connection with merger.

        Mr. Perry's 2009 and 2007 Supplemental Executive Retirement Plans are funded by insurance policies that Pacific Premier will receive in the merger. At May 10, 2013, the life insurance policies to be received by Pacific Premier had an aggregate cash value of approximately $2,900,962 with death benefits of approximately $7,700,452 payable to SDTB.

Table of Contents

        Effect of the Merger on Deferred Compensation Plan.    In 2011, SDTB and Mr. Perry entered into a Deferred Compensation Plan designed to provide retirement payments to him for five years after the 2009 Supplemental Executive Retirement Plan payments cease. Absent his termination in connection with this merger, payments to Mr. Perry would commence ten years after retirement at age 56 or older, and continue for five years. As a result of his termination in connection with the merger, Mr. Perry will receive annual payments of $161,580 payable monthly, for five years, beginning ten years after completion of the merger.

        Aggregate Cash Payments to Mr. Perry.    Assuming that the merger is consummated on June 30, 2013 upon the closing of the merger, pursuant to the terms of his confidentiality, non-competition and non-solicitation agreement with the Bank, as well as his employment agreement, SDTB stock options and other contractual arrangements with SDTB, Mr. Perry will be entitled to receive an aggregate of $3,274,475. In addition, Pacific Premier will assume SDTB's obligations under the Supplemental Executive Retirement Plans with Mr. Perry and Mr. Perry's deferred compensation agreement, which will entitle Mr. Perry to receive an aggregate of $3,586,690 over the 15 years following the closing of the merger, for which Pacific Premier will accrue a liability, in addition to SDTB's existing liability, in the amount of $1,648,151.

        The following is a tabular presentation of the payments and benefits payable to Mr. Perry in connection with the merger, as described above. The amounts set forth in the table below are approximate and based upon the assumption that the merger is completed on June 30, 2013. An earlier or later closing date for the merger would cause certain of the amounts to change, although any such changes are not expected to be material. The amounts set forth in the table below are also on a pre-tax

Based on an estimated SDTB share value of $13.41.

        The cash portion of the merger consideration will be subject to downward adjustment if SDTB's aggregate transaction-related expenses exceed $3.0 million, on an after-tax equivalent basis. Pursuant to the terms of the merger agreement, SDTB's transaction-related expenses consist of certain fixed amounts, such as SDTB's accounting and advisory fees and expenses associated with the accrual of benefits and payments payable to Mr. Perry described above, which are estimated to amount to $2.7 million in the aggregate on an after-tax basis, of which $2.5 million is associated with the accrual of benefits and payments payable to Mr. Perry described above. SDTB's transaction-related expenses also consist of certain amounts that are not fixed, such as SDTB's legal fees and premiums for extended directors' and officers' liability insurance to the extent premiums exceed 200% of current

80


Table of Contents

SDTB premiums. To the extent that the variable amounts cause SDTB's aggregate transaction-related expenses to exceed $3.0 million, on an after-tax equivalent basis, and the cash portion of the merger consideration is reduced by such excess, all of SDTB's transaction-related expenses, including the payments made to Mr. Perry, the liability accrued by Pacific Premier related to future payments to Mr. Perry and the premiums for extended directors' and officers' liability insurance, to the extent premiums exceed 200% of current SDTB premiums, will have the effect of reducing the merger consideration payable to SDTB's shareholders. The cash portion of the merger consideration is not subject to an upward adjustment if SDTB's aggregate transaction-related expenses are less than $3.0 million, on an after-tax equivalent basis. Although no assurances can be made as to the final amount of SDTB's aggregate transaction-related expenses, SDTB does not anticipate that its variable transaction-related expenses will cause its aggregate transaction-related expenses to exceed $3.0 million.

        Indemnification.    SDTB's directors, officers and employees are entitled to continuing indemnification against certain liabilities by virtue of provisions contained in the SDTB amended articles of association and bylaws, as amended, and the merger agreement. 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 SDTB, 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 SDTB or is or was serving at the request of SDTB 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 articles of incorporation and bylaws of SDTB, or any agreement, arrangement or understanding previously disclosed by SDTB 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 purchase an extended reporting period endorsement under SDTB's existing directors' and officers' liability insurance policy for SDTB'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 three (3) years, provided that if the cost of such insurance exceeds 200% of the annual premiums paid by SDTB for its existing directors' and officers' liability insurance, which is referred to as the maximum insurance amount, SDTB, at its discretion, shall either (a) obtain such insurance, with the excess cost and expense being considered transaction expenses for purposes of determining whether SDTB's transaction expenses exceed $3.0 million on an after-tax equivalent basis, and thus reduce the per share cash consideration pursuant to the terms of the merger agreement, or (b) obtain the most advantageous coverage as is available for the maximum insurance amount.

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

Material Federal Income Tax Consequences

        In the opinion of Patton Boggs LLP, counsel to Pacific Premier, the material U.S. federal income tax consequences of the merger are set forth below. This discussion is based upon the Code, Treasury regulations, judicial authorities, published positions of the IRS, and other applicable authorities, 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 SDTB 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 SDTB common stock as capital assets 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 SDTB 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 SDTB common stock as part of a straddle, hedge, constructive sale or conversion transaction, and U.S. holders that acquired their shares of SDTB 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 SDTB 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 SDTB 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 SDTB common stock that for U.S. federal income tax purposes is (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 the District of Columbia, (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.    As a condition to the completion of the merger, Patton Boggs 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 rendering the opinion, counsel will rely on the representations of Pacific Premier and SDTB, 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.

Table of Contents

        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 SDTB 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 contained in representation letters of officers of Pacific Premier and SDTB, 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 Patton Boggs 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, the Bank and SDTB.    No gain or loss will be recognized by Pacific Premier, the Bank or SDTB as a result of the merger.

        Tax Consequences of the Merger for U.S. Holders of SDTB Common Stock.    The U.S. federal income tax consequences of the merger to a U.S. holder of SDTB common stock will depend on whether such U.S. holder receives shares of Pacific Premier common stock, cash or a combination of cash and Pacific Premier common stock in exchange for such U.S. holder's SDTB common stock. As discussed above under "—The Merger Consideration" beginning on page 57, SDTB shareholders will make a stock, cash or mixed stock/cash election pursuant to the terms of the merger agreement. Shares held by those SDTB shareholders who do not make an election to receive cash, stock or a combination of cash and stock will treated as no-election shares and allocated merger consideration as provided in the merger agreement. An SDTB shareholder will not know the exact amount or the form of consideration they will receive. As a result, the tax consequences to such SDTB shareholder will not be ascertainable with certainty until such shareholder knows the precise number of shares of Pacific Premier common stock and/or amount of cash that it will receive pursuant to the merger.

        Exchange of SDTB common stock solely for Pacific Premier common stock.    Except as discussed below under "—Cash in Lieu of Fractional Shares of Pacific Premier Common Stock," a U.S. holder that exchanges all of their shares of SDTB common stock solely 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 SDTB 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 SDTB common stock exchanged therefor.

        Exchange of SDTB common stock solely for cash.    A U.S. holder that exchanges all of its shares of SDTB common stock solely for cash pursuant to the merger will recognize gain or loss equal to the difference between the amount of cash received by such U.S. holder and the U.S. holder's adjusted tax basis in the SDTB common stock exchanged therefor, provided that such U.S. holder does not otherwise already own, either actually or constructively, shares of Pacific Premier Common Stock. Any gain or loss will be capital gain or loss. Any capital gain or loss will be long-term capital gain or loss if the U.S. holder held the shares of SDTB common stock for more than one year at 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.

83


Table of Contents

        In some cases, if a U.S. holder actually or constructively owns shares of Pacific Premier common stock other than shares of Pacific Premier common stock received pursuant to the merger, the receipt of the cash may not be treated as capital gain and instead treated as having the effect of the distribution of a dividend to the U.S. holder under the tests set forth in Section 302 of the Code. These tests are complex and dependent upon the specific factual circumstances particular to each U.S. holder. As such, it is not possible to provide an opinion as to whether these tests would apply. If these tests do apply to treat the receipt of the cash as having the effect of the distribution of a dividend, then this would mean that, notwithstanding the previous paragraph, the U.S. holder may not recognize gain or loss and up to the entire amount of the cash would be treated as ordinary dividend income. Consequently, each U.S. holder that may be subject to those rules should consult its tax advisor as to the application of these rules to the particular facts relevant to such U.S. holder.

        Exchange of SDTB common stock for a combination of Pacific Premier common stock and cash.    Except as discussed below under "—Cash in Lieu of Fractional Shares of Pacific Premier Common Stock," a U.S. holder that exchanges shares of SDTB common stock for a combination of Pacific Premier common stock and cash pursuant to the merger will recognize gain (but not loss) equal to the lesser of (i) the excess, if any, of the amount of cash plus the fair market value of any Pacific Premier common stock received in the merger, over such U.S. holder's adjusted tax basis in the shares of SDTB common stock surrendered by such U.S. holder in the merger and (ii) the amount of cash received by such U.S. holder in the merger (other than cash received in lieu of fractional shares of Pacific Premier common stock).

        A U.S. holder's aggregate tax basis in the 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 equal such U.S. holder's aggregate tax basis in the SDTB common stock surrendered in the merger, increased by the amount of taxable gain or dividend income (discussed below), if any, recognized by such U.S. holder in the merger (other than with respect to cash received in lieu of fractional shares of Pacific Premier common stock), and decreased by the amount of cash, if any, received by such U.S. holder in the merger (other than cash received in lieu of fractional shares of Pacific Premier common stock). The holding period for the shares of 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 include the holding period for the shares of SDTB common stock exchanged therefor.

        Any gain will be capital gain unless the U.S. holder actually or constructively owns Pacific Premier common stock immediately after the merger. In that case, the receipt of the cash may be treated as having the effect of the distribution of a dividend to the U.S. holder under the tests set forth in Section 302 of the Code and as described above.

        Any capital gain or loss will be long-term capital gain or loss if the U.S. holder held the shares of SDTB common stock for more than one year at 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.

        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 SDTB common stock allocable to such

84


Table of Contents

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 SDTB 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.

        Notwithstanding the previous paragraph, if the receipt of the cash has the effect of the distribution of a dividend to the U.S. holder, as described above, all or portion of the cash would be treated as ordinary dividend income as described above.

        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 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 SDTB common stock surrendered and the fair market value (determined immediately before the exchange) of the SDTB 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 SDTB (by vote or value) or securities of SDTB 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 SDTB SHAREHOLDERS. SDTB 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 purchase method of accounting under GAAP. Under this method, SDTB'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 SDTB and the fair value of the identifiable net assets acquired (including core deposit intangibles) will be recorded as goodwill. In accordance with Statement of Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets," issued in July 2001, 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 SDTB beginning on the date of completion of the merger.

Expenses of the Merger

        The merger agreement provides that each of SDTB and Pacific Premier will bear and pay all costs and expenses incurred by it in connection with the transactions contemplated by the merger agreement, except that Pacific Premier will pay at closing up to $3.0 million, on an after-tax equivalent basis, of SDTB's transaction-related expenses, which includes certain fixed amounts, such as SDTB's accounting and advisory fees and expenses associated with the accrual of benefits, change in control and other contractual payments and non-competition payments payable to SDTB's Chairman, Chief Executive Officer and President, Michael E. Perry, which are further discussed in the Section entitled "—Interests of Certain SDTB Officers and Directors in the Merger—Aggregate Cash Payments to Mr. Perry" beginning on page 79, as well as certain amounts that are not fixed, such as SDTB's legal fees and premiums for extended directors and officers liability insurance to the extent premiums exceed 200% of current SDTB premiums.

        To the extent that SDTB's aggregate expenses related to the merger, whether paid by SDTB prior to closing or by Pacific Premier at closing, exceed $3.0 million on an after-tax equivalent basis, any excess shall reduce the per share cash consideration by the quotient of (i) such excess expense amount divided by (ii) the total number of shares of issued and outstanding SDTB common stock. The per share cash consideration will not be increased if SDTB's aggregate expenses related to the merger, whether paid by SDTB prior to closing or by Pacific Premier at closing, are less than $3.0 million on an after-tax equivalent basis. Although no assurances can be made as to the final amount of SDTB's aggregate expenses related to the merger, SDTB does not anticipate that its aggregate expenses related to the merger, on an after-tax basis, will exceed $3.0 million based on currently available information. See "—The Merger Consideration" beginning on page 57. The cash portion of the merger consideration is not subject to an upward adjustment if SDTB's aggregate transaction-related expenses are less than $3.0 million, on an after-tax equivalent basis.

        Any costs or expenses related to (i) any claims brought by a third party against SDTB in connection with the merger, (ii) any retention payments made or to be made to SDTB employees, (iii) the acceleration of SDTB options, or (iv) purchasing an extended reporting period endorsement under SDTB's existing directors' and officers' liability insurance policy or a substitute policy, as described in "Interests of Certain SDTB Officers and Directors in the Merger—Indemnification" on page 81, to the extent the cost of such insurance does not exceed 200% of the annual premiums paid by SDTB for its existing directors' and officers' liability insurance policy, will not be considered SDTB transaction-related expenses or count towards the $3.0 million limit.

        As of May 9, 2013, which is the latest practicable date before the filing of this proxy statement/prospectus, the aggregate amount of estimated fixed transaction-related expenses plus the variable transaction-related expenses actually incurred by SDTB, on an after-tax equivalent basis, was approximately $2.8 million. Although no assurances can be made as to the final amount of SDTB's transaction-related expenses as of the closing date of the merger, SDTB does not anticipate that its transaction-related expenses, on an after-tax basis, will exceed $3.0 million based on currently available information.


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 SDTB shareholders in the merger to be approved for listing on the Nasdaq Global Market.


Resale of Pacific Premier Common Stock

        The shares of common stock that SDTB shareholders receive as a result of the merger will be registered under the Securities Act. SDTB shareholders may freely trade these shares of Pacific

86


Table of Contents

Premier common stock if such SDTB 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, executive officers and directors of SDTB entered into a shareholder agreement with Pacific Premier pursuant to which each such executive officer and director agreed that at any meeting of the shareholders of SDTB, or in connection with any written consent of the shareholders of SDTB, the executive officer and director shall:

        Pursuant to the shareholder agreement, each SDTB executive officer and director 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 SDTB executive officer and director 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.

87


Table of Contents

        In addition, each SDTB executive officer and director agreed that, for a period of two (2) years following the consummation of the merger, they will not:

        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

        SDTB shareholders have the right to dissent from the merger and assert dissenters' rights, provided the requirements of the CGCL are followed. Any SDTB shareholder electing to exercise dissenters' rights must strictly comply with the provisions of Chapter of the CGCL.

        The following is intended to be a summary of the material provisions of the California statutory procedures required to be followed SDTB shareholders in order to demand and perfect dissenters' rights. This summary, however, is not a complete statement of all applicable requirements and is qualified in its entirety by reference to Chapter 13 of the CGCL. The full text of these dissenters' provisions is reproduced in its entirety in Appendix C to this proxy statement/prospectus. If an SDTB shareholder wishes to consider exercising dissenters' rights, they should carefully review the text of Chapter 13 of the CGCL, since failure to timely and properly comply with the requirements of Chapter of the CGCL will result in the loss of dissenters' rights under California law.

        Chapter 13 of the CGCL provides SDTB shareholders who do not vote "FOR" approval of the merger agreement with the right, subject to compliance with the requirements summarized below, to dissent and demand the payment of, and to be paid in cash for, the fair market value of the shares of SDTB common stock owned by such SDTB shareholders as of the close of business on May 9, 2013, the record date for SDTB's special shareholders meeting to consider and vote upon the merger agreement. The fair market value of shares of SDTB common stock is determined as of March 5, 2013, which was the last day before the first public announcement of the terms of the merger.

        Not Vote "FOR" the Merger Agreement.    Any SDTB shareholder who desires to exercise dissenters' rights must not have voted his, her or its shares of SDTB common stock "FOR" approval of the merger agreement. If an SDTB shareholder returns a proxy without voting instructions or with instructions to vote "FOR" approval of the merger agreement, or votes in person at the SDTB shareholders special meeting "FOR" approval of the merger agreement, his, her or its shares of SDTB common stock will be counted as votes in favor of the merger agreement and such shareholder will lose any dissenters' rights. Thus, if an SDTB shareholder wishes to dissent and they execute and return a proxy, they must specify that their shares of SDTB common stock are to be voted "AGAINST" or "ABSTAIN" with respect to approval of the merger agreement.

        Written Demand for Payment.    To preserve dissenters' rights, an SDTB shareholder must make a written demand for the purchase of their shares of SDTB common stock and payment to them of the fair market value of their shares of SDTB common stock within 30 days after the date on which notice

88


Table of Contents

of SDTB shareholder approval (as described immediately below) of the merger agreement is mailed. Simply failing to vote for, or voting against, the merger agreement does not constitute a proper written demand under the CGCL. To comply with the requirements under the CGCL, the written demand must:

        Any written demands for payment from SDTB shareholders should be sent to SDTB at San Diego Trust Bank, 2550 Fifth Avenue, Suite 1010, San Diego, California 92103, Attention: Corporate Secretary. In the event the merger is consummated before the end of the 30-day period described above, the submissions may be made to Pacific Premier at Pacific Premier Bancorp, Inc., 17901 Von Karman Ave., Suite 1200, Irvine, California 92614, Attention: Corporate Secretary. Shares of SDTB common stock held by shareholders who have perfected their dissenters' rights in accordance with Chapter 13 of the CGCL and have not withdrawn their demands or otherwise lost their dissenters' rights are referred to in this summary as "dissenting shares."

        Notice of Approval.    If SDTB's shareholders approve the merger agreement, SDTB (or Pacific Premier, as its successor) is required within ten (10) days after the approval to send to those SDTB shareholders who did not vote "FOR" approval of the merger agreement a written notice of SDTB shareholder approval, accompanied by a copy of Sections 1300, 1302, 1303 and 1304 of the CGCL, a statement of the price determined by SDTB (or Pacific Premier, as its successor) to represent the fair market value of the dissenting shares as of March 5, 2013, and a brief description of the procedure to be followed if the SDTB shareholder desires to exercise the shareholder's dissenters' right under the CGCL. The statement of price determined by SDTB (or Pacific Premier, as its successor) to represent the fair market value of dissenting shares, as set forth in the notice of approval, will constitute an offer by SDTB (or Pacific Premier, as its successor) to purchase the dissenting shares at the stated price if the merger closes and the dissenting shares do not otherwise lose their status as such. Within 30 days after the date of the mailing of the notice of SDTB shareholder approval, a dissenting SDTB shareholder must submit to SDTB (or Pacific Premier, as its successor), or SDTB's transfer agent, for endorsement as dissenting shares, the stock certificates representing their shares of SDTB common stock as to which such SDTB shareholder is exercising dissenter's rights. If the dissenting shares are uncertificated, then the SDTB shareholder must provide written notice of the number of shares of SDTB common stock which the shareholder demands that SDTB (or Pacific Premier, as its successor) purchase within 30 days after the date of the mailing of the notice of SDTB shareholder approval.

        Submissions can be made to SDTB (or Pacific Premier, as successor) as described above, or to SDTB's transfer agent, Computershare, at 350 Indiana Street, Suite 750, Golden, CO, 80401, Attention: Adam Burnham.

        Payment of Agreed-Upon Price.    If SDTB (or Pacific Premier, as its successor) and a dissenting SDTB shareholder agree that the shareholder's shares SDTB common stock are dissenting shares and agree upon the price of the dissenting shares, the dissenting SDTB shareholder is entitled to receive

89


Table of Contents

the agreed price with interest at the legal rate on judgments from the date of that agreement. Payment for the dissenting shares must be made within 30 days after the later of the date of that agreement or the date on which all statutory and contractual conditions to the mergers are satisfied. Payments are also conditioned on the surrender of the certificates representing the dissenting shares.

        Determination of Dissenting Shares or Fair Market Value.    If SDTB (or Pacific Premier, as its successor) denies that the dissenting SDTB shareholder's shares of SDTB common stock are dissenting shares, or SDTB and the SDTB shareholder fail to agree upon the fair market value of the dissenting shares, then, within six months after the notice of SDTB shareholder approval of the merger is sent by SDTB (or Pacific Premier, as its successor), any SDTB shareholder demanding purchase of their shares of SDTB common stock as dissenting shares or any interested corporation may file a complaint in the superior court in the proper county praying the court to determine whether the shares of SDTB common stock are dissenting shares or the fair market value of the dissenting shares, or both, or may intervene in any action pending on such a complaint. If a complaint is not filed or intervention in a pending action is not made within the specified six-month period, the dissenters' rights are lost. If the fair market value of the dissenting shares is at issue, the court will determine, or will appoint one or more impartial appraisers to determine, such fair market value.

        On the trial of the action, the court determines the issues. If the status of the SDTB shareholder's shares of SDTB common stock as dissenting shares is in issue, the court first determines that issue. If the fair market value of the dissenting shares is in issue, the court determines, or appoints one or more impartial appraisers to determine, the fair market value of the dissenting shares.

        If the court appoints an appraiser or appraisers, the appraiser or appraisers shall proceed to determine the fair market value per share. Within the time fixed by the court, the appraisers, or a majority of the appraisers, shall make and file a report in the office of the clerk of the court. Thereafter, on the motion of any party, the report shall be submitted to the court and considered on such evidence as the court considers relevant. If the court finds the report reasonable, the court may confirm it.

        If the appraiser or appraisers fail to make and file a report within ten (10) days after the date of their appointment or within such further time as the court allows, or if the court does not confirm the report, the court will determine the fair market value of the dissenting shares. Subject to Section 1306 of the CGCL, the court will render a judgment against SDTB (or Pacific Premier, as its successor) for payment of an amount equal to the fair market value (as confirmed or determined by the court) of each dissenting share multiplied by the number of dissenting shares that any dissenting shareholder who is a party, or who has intervened, is entitled to require SDTB (or Pacific Premier, as its successor) to purchase, with interest at the legal rate from the date on which the judgment is entered. Any party may appeal from the judgment.

        The costs of the action, including reasonable compensation to the appraiser or appraisers to be fixed by the court, is assessed or apportioned as the court considers equitable. However, if the appraisal determined by the court is more than the price offered by SDTB (or Pacific Premier, as successor), SDTB (or Pacific Premier, as successor) will pay the costs, which may include, at the court's discretion, attorneys' fees, fees of expert witnesses and interest at the legal rate on judgments from the date the shareholder made the demand and submitted shares for endorsement if the value awarded by the court for the shares is more than 125% of the price offered by SDTB (or Pacific Premier, as successor).

        Maintenance of Dissenting Share Status.    Except as expressly limited by Chapter 13 of the CGCL, holders of dissenting shares continue to have all the rights and privileges incident to their shares of SDTB common stock until the fair market value of their shares of SDTB common stock is agreed upon or determined. A holder of dissenting shares may not withdraw a demand for payment unless SDTB (or Pacific Premier, as its successor) consents to the withdrawal.

Table of Contents

        Dissenting shares lose their status as dissenting shares, and dissenting SDTB shareholders cease to be entitled to require SDTB (or Pacific Premier, as its successor) to purchase their shares of SDTB common stock, upon the happening of any of the following:

        To the extent that the provisions of Chapter 5 of the CGCL (which place conditions on the power of a California corporation to make distributions to its shareholders) prevent the payment to any holders of dissenting shares of the fair market value of the dissenting shares, the dissenting SDTB shareholders will become creditors of SDTB (or Pacific Premier, as its successor) for the amount that they otherwise would have received in the repurchase of their dissenting shares, plus interest at the legal rate on judgments until the date of payment, but subordinate to all other creditors of SDTB (or Pacific Premier, as its successor) in any liquidation proceeding, with the debt to be payable when permissible under the provisions of Chapter 5 of the CGCL.

        SDTB shareholders should be aware that the fair value of any shares of SDTB common stock as determined under Section 1300 of the CGCL could be more, the same, or less than the merger consideration.

        The failure of an SDTB shareholder to comply strictly with the CGCL requirements will result in a loss of dissenters' rights. A copy of the relevant statutory provisions is attached as Appendix C. SDTB shareholders are urged to refer to Appendix C for a complete statement concerning dissenters' rights. The foregoing summary of such rights is qualified in its entirety by reference to Appendix C.

        Although Pacific Premier recently completed a public offering of its securities, issued additional shares of common stock in connection with the completion of the FAB acquisition and expects to issue additional shares of common stock in the merger to holders of SDTB common stock, Pacific Premier may continue to experience a limited trading market for its common stock, which may cause fluctuations in the market value of its common stock to be exaggerated, leading to price volatility in excess of that which would occur in a more active trading market of its common stock.

        Dividends.    During the periods presented in the table above, Pacific Premier did not pay any dividends on its common stock. It is Pacific Premier's current 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.

        Dividends.    SDTB has not declared or paid any dividends to date during 2013. SDTB declared and paid a 3% stock dividend in each of April 2011 and April 2012. Payment of stock or cash dividends in the future will depend upon its earnings and financial condition and other factors deemed relevant by its board of directors, as well as its legal ability to pay dividends, which are discussed below. Pursuant to the merger agreement, SDTB has certain restrictions on the payment of dividends to its shareholders pending the closing of the merger. See "The Merger—Business Pending the Merger" beginning on page 67.

        Holders of SDTB common stock are entitled to receive dividends, on a pro rata basis, as and when declared by its board of directors, out of funds legally available for the payment of dividends and as specified and limited by the California Financial Code and other banking regulations. Under Section 1132 of the California Financial Code, funds available for cash dividend payments by a bank are restricted to the lesser of a bank's retained earnings or a bank's net income for its last three fiscal years (less any distributions to shareholders made during such period). Notwithstanding the provisions of Section 1132 of the California Financial Code, under Section 1133 thereof, a bank or a majority-owned subsidiary of a bank may, with prior approval from the California Department of Financial Institutions, the DFI, make a distribution to its shareholders in an amount not exceeding the greater of: (a) the retained earnings of the bank; (b) the net income of the bank for its last fiscal year; or (c) the net income of the bank for its current fiscal year. Notwithstanding the provisions of Section 1132 of the California Financial Code, under Section 1134 thereof, with prior DFI approval, a bank may make a distribution to its shareholders by means of redeeming its redeemable shares, and with prior DFI approval as well as the approval of the bank's outstanding shares, a bank may make a distribution to its shareholders in connection with a reduction of its contributed capital.

        If CA DFI finds that the shareholders' equity of SDTB is not adequate or that the payment of a dividend would be unsafe or unsound for SDTB, CA DFI may order SDTB not to pay a dividend to its shareholders. The Federal Deposit Insurance Corporation, the FDIC, also has the authority to prohibit

93

a bank from engaging in business practices (including payment of dividends) considered by the FDIC to be unsafe or unsound.

Equivalent Market Value Per Share of SDTB Common Stock

        The following table sets forth the closing sale prices of (i) Pacific Premier common stock as reported on the Nasdaq Stock Market, and (ii) SDTB common stock as quoted on the OTCQB, on March 5, 2013, the last trading-day before Pacific Premier announced the merger, and on May 9, 2013, the last practicable trading-day before the distribution of this proxy statement/prospectus. To help illustrate the market value of the per share stock consideration to be received by SDTB's shareholders, the following table also presents the equivalent market value per share of SDTB common stock as of March 5, 2013 and May 9, 2013, which were determined by multiplying the closing price for Pacific Premier's common stock on those dates by the exchange ratio of 1.114 of a share of Pacific Premier common stock for each share of SDTB common stock. The equivalent market value per share of SDTB common stock presented below does not reflect the possible upward or downward adjustment if the PPBI Average Share Price is less than $10.832 or greater than $13.240, or the per share cash consideration that may also be received by holders of SDTB common stock. See "The Merger—The Merger Consideration" beginning on page 57 for additional information about the merger consideration to be received by holders of SDTB common stock, including the possible adjustments to the per share cash consideration and the per share stock consideration.

        Because the price of Pacific Premier common stock could fluctuate during the period of time when you elect the form of merger consideration that you wish to receive and the time you actually receive your shares of Pacific Premier common stock as merger consideration, you will be subject to the risk of a decline in the price of Pacific Premier common stock during this period. Shareholders are advised to obtain current market quotations for Pacific Premier common stock. The market price of Pacific Premier common stock at the effective time of the merger or at the time shareholders of SDTB receive Pacific Premier common stock in the merger following the consummation of the merger may be higher or lower than the market price at the time the merger agreement was executed, at the date of mailing of this proxy statement/prospectus or at the time of the special meeting.

INFORMATION ABOUT PACIFIC PREMIER

General

        Pacific Premier is a California-based bank holding company for the Bank, a California-chartered commercial bank. Pacific Premier's principal asset is all of the capital stock of the Bank. The Bank provides banking services to businesses, professionals and consumers in its primary market area of Southern California through ten locations in the cities of San Bernardino, Seal Beach, Huntington Beach, Los Alamitos, Irvine, Newport Beach, Palm Springs and Palm Desert, California. On March 15, 2013, the Bank completed its acquisition of First Associations Bank, or FAB, which added a new office in Dallas, Texas. The banking operations conducted in this new office will be exclusively focused on providing deposit and other services to homeowners associations, or HOAs, and HOA management companies nationwide. Through the Bank's branches and its Internet website at www.ppbi.com, the Bank offers a broad array of deposit and loan products and services for both businesses and consumer customers. As of December 31, 2012, Pacific Premier had, on a consolidated basis, total assets of $1.2 billion, total stockholders' equity of $134.5 million and total deposits of $904.8 million. At December 31, 2012, Pacific Premier had real estate loans and business loans collateralized by real estate totaling 67.9% of its gross loan portfolio. Beginning with the 2013 fiscal year, Pacific Premier's filing status with the Commission transitioned from a "smaller reporting company" to an "accelerated filer," as those terms are defined under Commission rules. Under the Commission's rules, Pacific Premier is permitted to continue to provide the scaled disclosure required of a "smaller reporting company" in its filings with the Commission until its quarterly report on Form 10-Q for the quarter ended March 31, 2013.

        Based on information contained in Schedule 13Ds, Schedule 13Gs and Schedule 13Fs filed with the Commission, there are two shareholders (each of which is an institutional shareholder) who collectively beneficially own an aggregate of approximately 14.81% of Pacific Premier's outstanding common stock. These two shareholders, together with the shares of Pacific Premier common stock beneficially owned by Steven Gardner, Pacific Premier's president and chief executive officer, beneficially own an aggregate of approximately 15.63% of Pacific Premier's outstanding common stock. Pacific Premier is not aware of any agreements, arrangements or understandings between such shareholders with respect to the voting or disposition of any shares of Pacific Premier common stock. The 495,000 shares of Pacific Premier common stock issued in connection with the underwriters' exercise of their over-allotment option issued as part of its public offering of common stock in December 2012 are included in the calculation of these aggregate beneficial ownership percentages. Other than as publicly disclosed in their respective Schedule 13Ds, Schedule 13Gs or Schedule 13Fs filed with the Commission, Pacific Premier is not aware of any increase or decrease in the beneficial ownership of these seven shareholders, including as a result of the shares of common stock sold in Pacific Premier's recently completed public offering. To the extent that any of these seven shareholders purchased additional shares of Pacific Premier common stock in the offering, or purchased or sold shares of Pacific Premier common stock in the open market, through privately negotiated transactions or otherwise, their collective beneficial ownership of shares of Pacific Premier's common stock could have changed from the percentages provided above.

        On January 9, 2013, Pacific Premier issued 495,000 shares of its common stock at a public offering price of $10.00 per share in connection with the underwriters' exercise of the over-allotment option granted to them as part of Pacific Premier's public offering of common stock in December 2012. The net proceeds from the offering after, including the underwriters' exercise of the over-allotment option, deducting underwriting discounts and commissions and estimated offering expenses were approximately $4.7 million. Pacific Premier intends to use the net proceeds of this offering for general corporate purposes, to support its ongoing and future anticipated growth and to augment the capitalization of the Bank. As of the date of this proxy statement/prospectus, the net proceeds from this offering have not

95

been applied for any specific purpose other than being available to Pacific Premier and the Bank for general corporate purposes.

        Pacific Premier's principal executive offices are located at 17901 Von Karman Ave., Suite 1200, Irvine, California 92614 and its telephone number is (949) 864-8000.


Management and Additional Information

        Certain information relating to director and executive compensation, benefit plans, voting securities and the principal holders thereof, certain relationships and related transactions and other related matters as to Pacific Premier set forth in Pacific Premier's annual report on Form 10-K, as amended, for the year ended December 31, 2012 or from Pacific Premier's 2013 annual meeting proxy statement, which are incorporated herein by reference.

INFORMATION ABOUT SDTB

Business

        SDTB is a California state chartered bank headquartered in San Diego, California. It was incorporated in June of 2003, opened for business in October of 2003, and currently operates three full-service offices in the San Diego California metropolitan area.

        SDTB is licensed to operate as a commercial bank under the California Banking Law and is subject to supervision by the California Department of Financial Institutions. In accordance with the Federal Deposit Insurance Act, the Federal Deposit Insurance Corporation insures the deposits of SDTB up to the maximum legal limit. SDTB's primary source of revenue is from investment securities and also from providing loans to customers, who are predominately small and middle-market businesses and individuals.

        SDTB offers a defined range of banking products, tailored to meet the needs of its customers, which includes secured and unsecured personal loans and lines of credit, commercial lines of credit, commercial loans for equipment financing, residential and commercial real estate loans, construction loans and bridge loans. SDTB also offer a variety of deposit products, including demand deposit accounts, interest-bearing checking accounts, money market accounts and certificates of deposit.

        At December 31, 2012, SDTB had total assets of $242 million, which were comprised of total investment securities of $135.8 million and total net loans of $36.2 million, total stockholders' equity of $25.7 million and total deposits of $187.9 million.


Competition

        The banking business in California, generally, and in SDTB's service areas, specifically, is highly competitive with respect to both loans and deposits and is dominated by a number of major banks that have many offices operating over wide geographic areas. SDTB competes for deposits and loans principally with these major banks, community banks, savings and loan associations, finance companies, credit unions and other financial institutions located in its market areas. Among the advantages that the major banks have over SDTB are their ability to finance extensive advertising campaigns and to allocate their investment assets to regions of highest yield and demand. Many of the major commercial banks operating in SDTB's service areas offer certain services (such as trust and international banking services) that are not offered directly by SDTB and, by virtue of their greater total capitalization, such banks have substantially higher lending limits.

96


Table of Contents

        As of June 30, 2012, the most recent period for which figures are available, data reported by the FDIC indicated that the 637 banks and savings and loan offices then open in SDTB's primary market area, San Diego County, held approximately $60.89 billion in total deposits averaging approximately $95.6 million per banking office. SDTB's total deposits (approximately $180.5 million) in the San Diego market area constituted approximately 0.30% of the total deposits in that market.

        Moreover, all banks face increasing competition for loans and deposits from non-bank financial intermediaries such as mortgage companies, insurance companies, credit unions and securities firms.

        In order to compete, SDTB uses to the fullest extent possible the familiarity of its directors and officers with the market area and its residents and businesses and the flexibility that SDTB's independent status will permit. This includes an emphasis on specialized services, local promotional activity, and personal contacts by directors, officers and other employees. SDTB uses newspaper advertising to inform the business community of the services it offers. SDTB also utilizes emerging marketing techniques, such as the Internet and e-mail marketing, to reach target markets.

        SDTB has developed programs that are specifically addressed to the needs of entrepreneurs and their closely held businesses, professionals and their professional service firms, high net worth and high income individuals, as well as local area businesses and non-profit organizations. In the event there are customers whose loan demands exceed SDTB's lending limits, it arranges for such loans on a participation basis with other financial institutions and intermediaries. SDTB also assists those customers requiring other services not offered by SDTB to obtain those services from correspondent banks. In addition, SDTB offers ATM services by offsetting fees from foreign ATMs, courier services, bank-by-mail services remote deposit capture, online banking and direct deposit services.


Premises

        SDTB leases approximately 5,610 square feet of office space for its headquarters located at 2550 Fifth Avenue, Suite 1010, San Diego, CA 92103. The lease is with an unaffiliated third party. The lease commenced on March 15, 2006 and terminates on April 30, 2018. The monthly base rent for the premises is $13,838.00 for 2013.

        SDTB leases approximately 6,126 square feet of office space for its branch office located at 2550 Fifth Avenue, Suite 120, San Diego, CA 92103. The lease is with an unaffiliated third party. The lease commenced on November 01, 2003 and currently is month-to-month with a monthly base rent of $18,932.98.

        SDTB leases approximately 4,879 square feet of office space for its branch office located at 781 Garden View Court, Suite 100, Encinitas, CA 92024. The lease is with an unaffiliated third party. The lease commenced on October 15, 2007 and terminates on October 15, 2017. The monthly base rent for the premises is $16,543.88 for 2013.

        SDTB leases approximately 1,710 square feet of office space for its branch office located at 1110 Rosecrans Street, Suite 101, San Diego, CA 92106. The lease is with an unaffiliated third party. The lease commenced on August 15, 2010 and terminates on August 15, 2014. The monthly base rent for the premises is $3,448.40 for 2013.

        SDTB believes that its premises will be adequate for present and anticipated needs. SDTB also believes that it has adequate insurance to cover its premises.

Legal Proceedings

        SDTB is from time to time involved in legal proceedings arising in the normal course of business. Other than proceedings incidental to SDTB's business, it is not a party to, nor is any of its property the subject of, any material pending legal or administrative proceedings.


Effect of Existing or Probable Governmental Regulations on the Business of SDTB

        As a state-chartered bank with deposits insured by the FDIC, SDTB is subject to extensive governmental regulations on its business. Federal, state and local laws and regulations regarding the discharge of harmful materials into the environment may also have an impact on SDTB. Since SDTB is not involved in any business that manufactures, uses or transports any material amount of chemicals, waste, pollutants or toxins that might have a material adverse effect on the environment, SDTB's primary exposure to environmental laws is through its lending activities and through properties or businesses SDTB may own, lease or acquire. Based on a general survey of SDTB's loan portfolio, conversations with local appraisers and the type of lending currently and historically done by SDTB, management is not aware of any potential liability for hazardous waste contamination that would be reasonably likely to have a material adverse effect on SDTB.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS OF SDTB

        This discussion presents the analysis of SDTB's financial condition and results of operations as of December 31, 2012 and 2011 and for each of the years in the two-year period ended December 31, 2012. This discussion is designed to provide a more comprehensive review of the operating results and financial position of SDTB than could be obtained from an examination of the financial statements alone. This discussion should be read in conjunction with the financial statements of SDTB and the notes related thereto which appear elsewhere in this proxy statement/prospectus. See "Index to SDTB Financial Statements" beginning on page F-1.

        Statements contained in this proxy statement/prospectus that are not purely historical are forward-looking statements within the meaning of Section 21E of the Exchange Act, including SDTB's expectations, intentions, beliefs or strategies regarding the future. All forward-looking statements concerning economic conditions, rates of growth, rates of income or values as may be included in this proxy statement/prospectus are based on information available to SDTB as of the date of this proxy statement/prospectus and SDTB assumes no obligation to update any such forward-looking statements. It is important to note that SDTB's actual results could materially differ from those in such forward-looking statements. Factors that could cause actual results to differ materially from those in such forward-looking statements include fluctuations in interest rates, inflation, government regulations, economic conditions and competitive product and pricing pressures in the geographic and business areas in which SDTB conducts its operations. See "Cautionary Statement Concerning Forward-Looking Statements" beginning on page 37.


General

        SDTB commenced operations on October 30, 2003 as a California-chartered commercial bank. SDTB is a member of the FDIC and is subject to the regulations of and periodic examinations by the CA DFI and the FDIC, its primary regulators.

        SDTB provides a wide range of financial services, including credit and deposit products, from its headquarters located in San Diego, California, as well as two full-service branches in the San Diego, California metropolitan area. SDTB's target clients include small and middle market businesses and individuals.

        SDTB's primary source of income is from the interest earned on loans and investment securities, and its primary expenses are interest paid on deposits and salaries and employee benefits.

        At December 31, 2012, SDTB had $242 million in total assets, $136 million in securities, $36 million in net loans, $188 million in total deposits and $26 million in total shareholders' equity.

        For the year ended December 31, 2012, net income totaled $1,815,000, or $0.82 per diluted share, compared to net income of $1,610,000, or $0.72 per diluted share, for the prior year. The increase in net income for the year ended December 31, 2012 was primarily due to an increase in gains on sale of securities of $196,000. SDTB recorded a (negative) provision for credit losses of ($450,000) and ($273,000) for the years ended December 31, 2012 and 2011, respectively, primarily related to a 25% decrease in the loan portfolio during the two years ended December 31, 2012 and the lack of any nonperforming or past due loans during that same period.

        The return on average total assets was 0.86% and 0.80% for 2012 and 2011, respectively. The return on average total shareholders' equity was 7.33% and 8.19% for 2012 and 2011, respectively.

Critical Accounting Policies

        SDTB's financial statements are prepared in accordance with accounting principles generally accepted in the United States of America and prevailing practices in the banking industry. The financial information contained within these statements is, to a significant extent, financial information that is based on approximate measures of the financial effects of transactions and events that have already occurred.

        Based on its consideration of accounting policies that involve the most complex and subjective decisions and assessments, management has identified its most critical accounting policy to be that related to the allowance for credit losses. SDTB's methodology to determine its allowance for credit losses incorporates a variety of risk considerations, both quantitative and qualitative, in establishing an allowance for credit losses that management believes is appropriate at each reporting date taking into account the characteristics of the loan portfolio, current economic conditions and historical credit loss experience. Although management believes that the level of the allowance as of December 31, 2012 is adequate to absorb losses inherent in SDTB's loan portfolio, a decline in the local economy or other adverse factors may result in increasing losses that cannot be reasonably predicted at this time. See "—Financial Condition" beginning on page 107.


Results of Operations

        Net Interest Income.    SDTB's earnings depend largely upon its net interest income, which is the difference between the income received from its loan and investment portfolios and other interest-earning assets and the interest paid on deposits and other interest-bearing liabilities. Net interest income, when expressed as a percentage of average total interest-earning assets, is referred to as the net interest margin. SDTB's net interest income is affected by changes in the level and mix of interest-earning assets and interest-bearing liabilities, which are referred to as volume changes. SDTB's net interest income is also affected by changes in the yields earned on assets and rates paid on liabilities, which are referred to as rate changes. Interest rates charged on SDTB's loans are affected principally by the demand for such loans, the supply of money available for lending purposes and competitive factors. Those factors are, in turn, affected by general economic conditions and other factors beyond SDTB's control, such as federal economic policies, the general supply of money in the economy, legislative tax policies, governmental budgetary matters and the actions of the Federal Reserve. Interest rates on deposits are affected primarily by rates charged by competitors.

        Net interest income totaled $6,495,000 for 2012, representing a decrease of $10,000, or 0.2%, from $6,505,000 for 2011. This decrease in net interest income reflects a $179,000 decrease in total interest income accompanied by a $168,000 decrease in total interest expense.

        Total interest income decreased $179,000, or 2.5%, in 2012 compared with 2011, primarily due to a lower yield of average interest-earning assets of 3.52% for 2012, which decreased from 3.85% in 2011.

        Total interest expense for the year ended December 31, 2012 decreased $169,000 or 24.6% from the year ended December 31, 2011. The decrease in total interest expense is primarily due to a decline in the rate paid on average interest-bearing liabilities, which decreased from 0.53% in 2011 to 0.40% in 2012.

        The noted decreases in interest income and interest expense are consistent with a protracted zero interest rate environment that has existed now for several years.

        Net Interest Margin and Net Interest Spread.    Net interest income, when expressed as a percentage of average total interest-earning assets, is referred to as the net interest margin. The net interest margin for the years ended December 31, 2012 and 2011 was 3.26% and 3.49%, respectively.

        The difference between the yield on average total interest-earning assets and the cost of average total interest-bearing liabilities is the net interest spread. The net interest spread is an indication of SDTB's ability to manage yields earned on loans and securities available-for-sale and rates paid on deposits and borrowings.

        For the year ended December 31, 2012, SDTB's net interest spread was 3.12%, as compared to 3.32% for the year ended December 31, 2011. Net interest spread did not change significantly between periods because the decrease in the yield on average total interest-earning assets was nearly offset by a decrease in the cost of average interest-bearing liabilities.

        The yield on average total interest-earning assets decreased from 3.85% for the year ended December 31, 2011 to 3.52% for the year ended December 31, 2012. The cost of average total interest-bearing liabilities declined from 0.53% for the year ended December 31, 2011 to 0.40% for the year ended December 31, 2012. Decreases in the yield on interest-earning assets occurred primarily as a result of maturities and pay-downs of loans and investment securities which were reinvested in lower yielding instruments as a result of the long downward trend in market interest rates. Decreases in the yield on interest-bearing liabilities were due to market-based downward adjustments to yields paid on various deposit products. These adjustments were made by SDTB management in response to the decreasing yields on interest-earning assets.

Loans are net of unamortized net deferred fees/costs. Amortized loan fees and costs have been included in the calculation of net interest income. Net loan fees recognized in interest income totaled $45,000 and $15,000 for the years ended December 31, 2012 and 2011, respectively.

        Provision for Credit Losses.    SDTB accounts for credit risk associated with lending activities through its allowance for credit losses and provision for credit losses. The provision for credit losses is the expense recognized in the statement of income to adjust the allowance for credit losses to the level deemed appropriate by management based upon application of SDTB's allowance methodology procedures. Specifically identifiable and quantifiable losses are immediately charged-off against the allowance for credit losses. The procedures for monitoring the adequacy of the allowance for credit losses, as well as detailed information about the allowance itself, are included below. See "—Financial Condition—Allowances for Credit Losses" beginning at page 110.

        For the years ended December 31, 2012 and 2011, SDTB recorded (negative) provisions for credit losses of ($450,000) and ($273,000), respectively. The (negative) provision for credit losses reflects the impact of management's continuing assessment of the credit quality of SDTB's loan portfolio, which is affected by a variety of factors including the size and composition of the loan portfolio, information about specific borrower situations, estimated collateral values and general economic factors and reflects a 25% decrease in the loan portfolio during the two-year period ended December 31, 2012 combined with the lack of any nonperforming loans in 2012 and 2011 during that same period.

        Noninterest Income.    For the years ended December 31, 2012 and 2011, total noninterest income was $918,000 and $663,000, respectively. The year-over-year increase is primarily attributable to a $196,000 increase in gains on the sale of securities available-for-sale.

        Noninterest Expense.    For the years ended December 31, 2012 and 2011, total noninterest expense was $5,495,000 and $5,574,000, respectively, reflecting a $79,000, or 1.4%, decrease year-over-year. The decrease was primarily due to reduced depreciation expense on leasehold improvements and equipment which related to a write-down of abandoned leasehold improvements and equipment in the amount of $56,000 that occurred in 2011 that did not re-occur in 2012.

Table of Contents

        Noninterest expense as a percentage of average total interest-earning assets improved to 2.76% for the year ended December 31, 2012, down from 2.99% for the year ended December 31, 2012. The efficiency ratio also improved year-over-year, declining from 80.3% in 2011 to 78.6% in 2012.

        Provision for Income Taxes.    For the years ended December 31, 2012 and 2011, SDTB's effective tax rate was 23.3% and 13.8%, respectively. The decrease in effective tax rate is primarily attributable to tax exempt income relating to municipal bonds and income from cash surrender value of bank-owned life insurance.


Market Risk/Interest Rate Risk Management

        Market risk is the risk of loss from adverse changes in market prices or rates. SDTB's market risk arises primarily from interest rate risk inherent in its lending, investment and deposit-taking activities. SDTB's profitability is affected by fluctuations in interest rates. A sudden and substantial change in interest rates may adversely impact SDTB's earnings to the extent that the interest rates borne by assets and liabilities do not change at the same speed, to the same extent or on the same basis. SDTB's management actively monitors and manages its interest rate exposure.

        Asset and liability management is concerned with the timing and magnitude of the repricing of assets and liabilities. It is SDTB's objective to control risks associated with interest rate movements within tolerances approved by its board of directors. In general, management's strategy is to match asset and liability balances within maturity and repricing categories to limit SDTB's exposure to earnings variations and variations in the value of assets and liabilities as interest rates change over time.

        Interest Rate Risk.    Interest rate risk is inherent in financial institutions and financial services companies. Interest rate risk results from assets and liabilities maturing or repricing at different times, from assets and liabilities repricing at the same time but in different amounts or from short-term and long-term interest rates changing by different amounts. Generally speaking, the rates of interest that SDTB earns on its assets, and pays on its liabilities, are established contractually for specified periods of time. Market interest rates change over time and if a financial institution cannot quickly adapt to interest rate changes, it may be exposed to volatility in earnings. For instance, if SDTB were to fund long-term fixed rate assets with short-term variable rate deposits and interest rates were to rise over the

104


Table of Contents

term of the assets, the short-term variable rate deposits would rise in cost and adversely affect net interest income. Similar risks exist when rate sensitive assets (for example, prime rate-based loans) are funded by longer-term fixed rate liabilities in a falling interest rate environment.

        SDTB uses two primary measurement processes on a quarterly basis to quantify and manage exposure to interest rate risk: net interest income and net income simulations and economic value of equity analyses. Net interest income and net income simulations are used to identify the direction and severity of interest rate risk exposure over a 12- and 24-month forecast horizon. Economic value of equity analyses are used to estimate the price sensitivity of shareholders' equity to changes in interest rates.

        SDTB also uses gap analysis to provide insight into mismatches of asset and liability cash flows. The interest rate sensitivity gap is determined by subtracting the amount of liabilities from the amount of assets that reprice during a particular time interval. A liability-sensitive position results when more assets than liabilities reprice within a given period. Conversely, an asset-sensitive position results when more assets than liabilities reprice within a given period.

        As of December 31, 2012, SDTB was generally liability sensitive at the measured time horizons, with a negative cumulative one-year gap of $66.0 million, or 27.3% of total assets, and a negative cumulative five-year gap of $42.6 million, or 17.6% of total assets. As more of its liabilities than assets will reprice over a five-year horizon, SDTB will realize lower net interest income in a rising rate environment and higher net interest income in a falling interest rate environment with all other conditions remaining constant.

        The following table sets forth the interest rate sensitivity of SDTB's interest-earning assets and interest-bearing liabilities as of December 31, 2012 using the interest rate sensitivity gap ratio. For the purposes of the following table, an asset or liability is considered rate-sensitive within a specified period when it can be repriced or matures within its contractual terms. Actual repricing patterns may differ

from contractual repricing patterns, particularly with mortgage-backed securities which comprise a significant portion of total securities available-for-sale.

Liquidity and Capital Resources

        Liquidity.    Liquidity is SDTB's ability to maintain sufficient cash flow to meet obligations as they come due, fund loan demand and take advantage of investment opportunities as they arise. Changes in liquidity can be anticipated or unanticipated. SDTB actively manages its liquidity on a daily basis because adequate liquidity is essential to address balance sheet fluctuations without causing undue rise in cost, risk or disruption to normal operating conditions. SDTB's Asset-Liability Management Committee and its board of directors periodically reviews SDTB's liquidity position.

        SDTB's principal sources of liquidity are deposit growth and principal and interest payments on loans and securities available-for-sale. To supplement these primary sources of liquidity, SDTB maintains contingent funding sources, which include unsecured overnight borrowing lines of credit totaling $9,000,000 at December 31, 2012 with two of its correspondent banks and secured borrowing facilities at the Federal Home Loan Bank of San Francisco, or the FHLB. At December 31, 2012,

106


Table of Contents

SDTB had a total borrowing capacity of $55 million at the FHLB with outstanding FHLB advances totaling $25 million, leaving unused borrowing capacity of $30 million. The outstanding advances matured on January 3, 2013 and carried an interest rate of 0.26%.

        Capital Resources.    Total shareholders' equity was $26 million at December 31, 2012, compared to $23 million at December 31, 2011. The primary reasons for the increase in total shareholders' equity have been an increase in net income of $1.8 million from 2011 to 2012, and a $1.1 million increase in the unrealized gain, net of tax, on securities available-for-sale.

        Management is committed to maintaining capital at a level to assure shareholders, customers and regulators that SDTB is financially sound and able to support its growth from its retained earnings. SDTB is subject to risk-based capital regulations adopted by the federal banking regulators. These guidelines are used to evaluate capital adequacy and are based on an institution's asset risk profile and off-balance sheet exposures. The risk-based capital guidelines assign risk weightings to assets both on- and off-balance sheet and place increased emphasis on common equity in the capital structure. According to the regulations, institutions whose Tier 1 risk-based capital ratio, total risk-based capital ratio and leverage ratio meet or exceed 6%, 10% and 5%, respectively, are generally deemed to be "well-capitalized". Based on these guidelines, SDTB's Tier 1 and total risk-based capital ratios at December 31, 2012 were 28.4% and 29.7%, compared to 25.6% and 26.9% at December 31, 2011, respectively. SDTB's leverage ratio was 9.7% at December 31, 2012, compared to 9.2% at December 31, 2011. All of SDTB's capital ratios were above the minimum regulatory requirements for a "well-capitalized" institution.

        Impact of Inflation.    The impact of inflation on a financial institution differs significantly from such impact on other companies. banks, as financial intermediaries, have assets and liabilities that tend to move in concert with inflation both as to interest rates, yields and value. A bank can reduce the impact of inflation if it can manage its interest rate sensitivity gap. SDTB attempts to structure its mix of financial instruments and manage its interest rate risk sensitivity gap in order to minimize the potential adverse effects of inflation or other market forces on its net interest income and therefore its earnings and capital. See "Interest Rate Risk." Inflation has been moderate in recent years and has had little or no effect on the financial condition and results of operations of SDTB during the periods covered in this proxy statement/prospectus.


Financial Condition

        Summary.    SDTB experienced growth in deposits in 2012 which also resulted in growth in total assets and securities available for sale. New funds received through increased deposits were primarily invested in securities available for sale due to a combination of poor loan demand and SDTB's conservative underwriting policies. Deposit growth was mainly attributable to increased deposits at a new branch opened in 2010 in the Point Loma area of San Diego, California. SDTB's reputation as a safe and secure institution during uncertain economic times also contributed to deposit growth in 2012.

        Total assets were $242 million at December 31, 2012, compared to $213 million at December 31, 2011, representing an increase of 13.6%.

        Total net loans were $37 million at December 31, 2012, compared to $40 million at December 31, 2011, representing a decrease of 7.5%.

        Total securities available-for-sale were $136 million at December 31, 2012, compared to $131 million at December 31, 2011, representing an increase of 3.8%.

        Total deposits were $188 million at December 31, 2012, compared to $169 million at December 31, 2011, representing an increase of 11.2%.

        Loans.    SDTB's loan portfolio represents approximately 15.4% of SDTB's total assets. The quality and diversification of its loan portfolio are important considerations when reviewing SDTB's results of operations.

        At December 31, 2012, total loans outstanding were $37.2 million, compared to $39.7 million at December 31, 2011. This decrease of 6.3% reflects SDTB's strict underwriting standards for new loans and the lack of loan demand in the current economic environment.

        Commitments.    During the ordinary course of business, SDTB will provide various forms of credit lines to meet the financing needs of its customers. These commitments to provide credit represent an obligation of SDTB to its customers which is not represented in any form in the balance sheet. These commitments include, to varying degrees, elements of credit and interest rate risk not recognized in SDTB's financial statements.

        The effect on SDTB's revenues, expenses, cash flows and liquidity from the unused portion of the commitments to provide credit cannot be reasonably predicted because there is no guarantee that the lines of credit will ever be used.

        At December 31, 2012 and December 31, 2011, SDTB had undisbursed loan commitments outstanding of $5.4 million whose contractual amounts represent credit risk.

        Nonperforming Assets.    Nonperforming assets are comprised of loans on nonaccrual status, loans 90 days or more but not on nonaccrual status, loans restructured where the terms of repayment have been renegotiated resulting in a reduction of deferral of interest or principal and other real estate owned, or OREO. Management generally places loans on nonaccrual status when they become 90 days past due, unless they are both fully secured and in the process of collection. Loans may be restructured by management when a borrower has experienced some change in financial status causing an inability to meet the original repayment terms and where SDTB believes the borrower will eventually overcome these circumstances to repay the loan in full. OREO consists of real property acquired through foreclosure or similar means that management intends to offer for sale.

        Management's classification of a loan as nonaccrual or restructured is an indication that there is reasonable doubt as to the full collectability of principal or interest on the loan. At this point, SDTB stops recognizing income from the interest on the loan and reverses any uncollected interest that has been accrued but unpaid. If the loan deteriorates further due to a borrower's bankruptcy or similar financial problems, unsuccessful collection efforts or a loss classification by regulators or auditors, the remaining balance of the loan is then charged-off. These loans may or may not be collateralized, but collection efforts are continuously pursued.

        SDTB had no nonperforming loans as of December 31, 2012 or December 31, 2011. SDTB had one parcel of OREO at December 31, 2012 and 2011 in the amount of $752,000.

A "restructured loan" is a loan whose terms were renegotiated to provide for a reduction or deferral of interest or principal because of a deterioration in the financial position of the borrower and where interest income is no longer recognized.

        Allowance for Credit Losses.    The allowance for credit losses reflects management's judgment of the level of allowance adequate to provide for probable losses inherent in the loan portfolio. On a quarterly basis, management assesses the overall adequacy of the allowance for credit losses utilizing a methodology which includes an individual analysis of specific categories of loans, specific categories of classified loans and individual classified loans. The adequacy of the allowance for credit losses is determinable only on an approximate basis since estimates as to the magnitude and timing of loan losses are not probable because of the impact of external events.

        Evaluation of the adequacy of the allowance for credit losses is based upon relevant information about the ability of borrowers to service their debt such as current financial information, historical payment experience, collateral adequacy and credit documentation as well as an amount for other factors that, in management's judgment, deserve recognition in estimating possible loan losses. These factors include, but are not limited to, historical charge-offs, estimated future losses on all significant loans, credit concentrations, certain classes or composition of loan, trends in the portfolio, delinquencies and nonaccruals, economic factors and the experience of management.

        The allowance for credit losses is established through a provision for credit losses charged to expense. Loan losses are charged against the allowance when management believes that the collectability of principal is unlikely. Subsequent recoveries of charged-off amounts are credited to the allowance for credit losses.

        For the year ended December 31, 2012, SDTB recorded a (negative) provision for credit losses of ($450,000), compared to a (negative) provision of ($273,000) for 2011. The negative provisions for credit losses for 2012 and 2011 were primarily related to a 25% decrease in the loan portfolio that occurred during the two-year period ended December 31, 2012, combined with the lack of any nonperforming or past due loans during that same period.

        Management is committed to maintaining the allowance for credit losses at a level that is considered to be commensurate with estimated and known risks in the loan portfolio. As of December 31, 2012, management believed that the allowance for credit losses of $1.0 million was adequate based on its assessment of such factors. However, no assurance can be given that economic conditions which adversely affect SDTB's service areas or other circumstances will result in increased provisions for credit losses or loan losses in the future.

        At December 31, 2012, the fair value of securities available-for-sale totaled $136 million, an increase of $5 million, or 3.8%, from $131 million at December 31, 2011. The primary reason for the growth of the securities portfolio during this period is strong deposit growth and weak loan demand as a result of anemic economic growth in SDTB's market area.

        At December 31, 2012, the securities portfolio had an unrealized gain of $7.7 million, compared to an unrealized gain of $5.9 million at December 31, 2011, with the increase primarily attributable to increasing investor preference for high quality U.S. government and insured municipal bonds such as those held by SDTB. The unrealized gain on available-for-sale securities is excluded from net income and reported net of income taxes as other comprehensive income in the shareholders' equity section of the balance sheet.

        SDTB realized gains on the sale of securities totaling $423,000 and $227,000 during the years ended December 31, 2012 and 2011, respectively.

UNAUDITED PRO FORMA COMBINED CONSOLIDATED FINANCIAL DATA

        The following Unaudited Pro Forma Condensed Combined Statement of Financial Condition combines the historical Consolidated Statement of Financial Condition of Pacific Premier and the historical Statement of Financial Condition of SDTB as of and for the year ended December 31, 2012 (i) on an actual historical basis; (ii) on an as adjusted basis after giving effect to the sale of 495,000 newly issued shares of Pacific Premier common stock in January 2013 in connection with the underwriters' exercise of the over-allotment option in Pacific Premier's recently completed underwritten public offering; and to the completion of the acquisition of FAB by Pacific Premier on March 15, 2013, including the issuance of 1,279,217 shares of Pacific Premier common stock and payment of $37.2 million in cash as consideration to the holders of FAB common stock in exchange for their shares; and (iii) assuming the completion of the merger on December 31, 2012, using the purchase method of accounting and giving effect to the related pro forma adjustments described in the accompanying Notes to the Unaudited Pro Forma Condensed Combined Financial Statements. The following Unaudited Pro Forma Condensed Combined Statements of Operations for both the year ended December 31, 2012, combine the historical Consolidated Statements of Operations of Pacific Premier and the historical Statements of Operations of SDTB giving effect to (x) the recently completed acquisition of FAB at the beginning of the period presented as further described in the accompanying Notes to Unaudited Pro Forma Condensed Combined Financial Statements (x) the sale of 495,000 newly issued shares of Pacific Premier common stock in its recently completed underwritten public offering at the beginning of the period presented as further described in the accompanying Notes to Unaudited Pro Forma Condensed Combined Financial Statements and (z) the merger as if the merger had become effective at the beginning of the period presented, using the purchase method of accounting and giving effect to the related pro forma adjustments described in the accompanying Notes to Unaudited Pro Forma Condensed Combined Financial Statements.

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

        The unaudited pro forma combined financial information included in this proxy statement/prospectus is 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 Pacific Premier public offering 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, FAB and SDTB. The historical consolidated financial statements of Pacific Premier and FAB are filed with the Commission and incorporated by reference into this proxy statement/prospectus. See "Where You Can Find More Information." The historical financial statements of SDTB are included elsewhere in this proxy statement/prospectus. See "Index to SDTB Financial Statements" beginning on page F-1.

        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 these periods.

        The unaudited pro forma combined 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 Pacific Premier for any period. Actual results may be materially different than the pro forma information presented.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

Note A—Basis of Presentation

        The unaudited pro forma combined condensed consolidated financial information and explanatory notes show the impact on the historical financial condition and results of operations of Pacific Premier resulting from (i) the sale of 495,000 newly issued shares of Pacific Premier common stock as part of the underwriters' over-allotment option in an underwritten public offering, as to which the closing of the shares occurred on January 9, 2013 and the receipt of net proceeds of approximately $4.7 million by Pacific Premier from the sale of such shares, (ii) the FAB merger under the purchase method of accounting and (iii) the SDTB merger under the purchase method of accounting. Under the purchase method of accounting, the assets and liabilities of both FAB and SDTB are recorded by Pacific Premier at their respective fair values as of the date the transaction is completed. The unaudited pro forma combined condensed consolidated statement of financial condition combines the historical financial information of Pacific Premier, FAB and SDTB as of December 31, 2012, as further adjusted after giving effect to the sale of 495,000 shares of newly issued Pacific Premier common stock as part of the underwriters' over-allotment option, as if the merger and the offering were completed on that date. The unaudited pro forma combined condensed consolidated statements of operations for the year ended December 31, 2012 gives effect to the merger of FAB and SDTB, as further adjusted after giving effect to the sale of 495,000 shares of newly issued Pacific Premier common stock as part of the underwriters' over-allotment option, as if the mergers and offering occurred on the first day of the year or January 1, 2012, using the purchase method of accounting and giving effect to the related pro forma adjustments described in the Notes to Unaudited Pro Forma Condensed Combined Financial Statements.

        Since the merger is recorded using the purchase 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 pro forma combined condensed consolidated statement of operations for the year ended December 31, 2012, Pacific Premier assumed no adjustments to the historical amount of FAB or SDTB's provision for credit losses. If such adjustments were estimated, there could be a reduction to the historical amounts of FAB's or SDTB's provision for credit losses presented.

Note B—Accounting Policies and Financial Statement Classifications

        The accounting policies of FAB and SDTB 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 operations with that of FAB's and SDTB'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, selling

Note C—Merger and Acquisition Integration Costs (Continued)

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 revenue enhancements and cost savings following the merger with FAB and SDTB. These revenue enhancements and 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.

Note E—SDTB Pro Forma Adjustments (Continued)

Note F—Effect of Hypothetical Adjustments on FAB's or SDTB's Historical Financial Statements

        The unaudited pro forma combined condensed consolidated statement of operations for the year ended December 31, 2012 present the pro forma results assuming the merger occurred on January 1, 2012. The pro forma financial statements for the year ended December 31, 2012 do not reflect any adjustments to eliminate FAB's or SDTB's historical provision for loan losses.

        FAB and SDTB's provision for loan losses for the period presented relates to loans that Pacific Premier is required to initially record at fair value. Such fair value adjustments include a component related to the expected lifetime credit losses on those loan portfolios. Pacific Premier believes that these same historical provisions would not have been recorded in Pacific Premier combined consolidated financial statements for the periods presented had the transactions been completed on January 1, 2012.

Table of Contents


DESCRIPTION OF PACIFIC PREMIER CAPITAL STOCK

        The following is a summary of the material 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. SDTB shareholders should read this summary together with the DGCL and 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 136.


Common Stock

        The Pacific Premier certificate of incorporation authorizes 25,000,000 shares of common stock, par value $0.01 per share. At May 9, 2013, there were 15,437,531 shares of Pacific Premier common stock issued and outstanding, held of record by approximately 2,089 stockholders. The Pacific Premier common stock is listed on the NASDAQ Global 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 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

125


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 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.

        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 SDTB who receive shares of Pacific Premier common stock in exchange for their shares of SDTB 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. SDTB is a California-chartered bank, and its shareholders' rights are governed by the CGCL and its articles of incorporation and bylaws. SDTB's articles of incorporation are referred to as the SDTB articles of incorporation, and SDTB's bylaws are referred to as the SDTB bylaws.

        After the merger, as Pacific Premier stockholders, the rights of former SDTB 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 SDTB 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 SDTB 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 SDTB, and other known material differences. For more detailed information with respect to Pacific Premier, see "Description of Pacific Premier Capital Stock" beginning on page 125.


Authorized Capital Stock

        Pacific Premier.    Pacific Premier's authorized capital stock consists of 25,000,000 shares of Pacific Premier common stock, par value $.01 per share, and 1,000,000 shares of Pacific Premier preferred stock, par value $.01 per share. The Pacific Premier certificate of incorporation authorizes Pacific Premier's board of directors to issue shares of Pacific Premier preferred stock in one or more series and to fix the designation, powers, preferences, and rights of the shares of Pacific Premier preferred stock in each series.

        SDTB.    SDTB's authorized capital stock consists of 10,000,000 shares of SDTB common stock and 10,000,000 shares of SDTB preferred stock. The SDTB articles of incorporation authorize SDTB's board of directors to issue shares of SDTB preferred stock in one or more series and to determine and alter the rights, preferences, privileges and restrictions granted to and imposed upon the shares of SDTB preferred stock in each series. The SDTB articles of incorporation also authorize SDTB's board of directors to increase or decrease the number of shares of any series of preferred stock subsequent to the issue of shares of that series, but not below the number of shares of such series then outstanding. As of May 9, 2013, there were 2,151,395 shares of SDTB common stock outstanding and no shares of SDTB preferred stock were outstanding.


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 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.

        SDTB.    Under the CGCL, SDTB may issue shares of SDTB stock for such consideration as may be determined by the SDTB board of directors in accordance with the CGCL. None of the CGCL or the SDTB articles of incorporation or bylaws require shareholder approval of any such actions. Under the CGCL, holders of SDTB stock do not have preemptive rights with respect to any shares of SDTB stock that may be issued, unless granted such rights in the SDTB articles of incorporation. The SDTB articles of incorporation do not grant such rights.


Voting Rights

        Pacific Premier.    Each holder of Pacific Premier common stock is entitled to one vote for each share held of record. All director elections shall be determined by a plurality of the votes cast and, except as otherwise required by law or the Pacific Premier certificate of incorporation, all other matters are determined by a majority of the votes cast. Holders of Pacific Premier common stock do not have cumulative voting rights with respect to the election of directors.

        SDTB.    With respect to all matters other than the election of directors, votes are taken on the basis of one vote for each share represented at the meeting in question, and except as otherwise required by law or the SDTB articles of incorporation, all other matters are determined by a majority of the votes cast. Pursuant to the SDTB bylaws, with respect to the election of directors, holders of SDTB stock have cumulative voting rights only 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 affirmative votes of shares entitled to be voted for them, up to the number of directors to be elected, are elected.


Number and Election of Directors

        Pacific Premier.    The Pacific Premier bylaws provide that the number of directors who shall constitute the board of directors shall be such number as the board of directors shall from time to time have designated, except that in the absence of such designation, such number shall be seven. The

128


Table of Contents

directors shall be elected by the stockholders each year at the annual meeting of stockholders and shall hold office until the next annual meeting and until each director's successor shall have been duly elected and qualified or until a director's earlier resignation or removal. Currently, Pacific Premier's board of directors consists of six directors.

        SDTB.    SDTB's bylaws provide for a board of directors consisting of no fewer than nine members nor more than fifteen members as determined from time to time by the SDTB board of directors or by SDTB's shareholders. Members of the SDTB board of directors serve one-year terms and are elected annually by SDTB's shareholders. Members of the SDTB board of directors, including those elected to fill a vacancy, hold office until the expiration of the term for which they were elected and until a successor has been elected and qualified. Currently, SDTB's board of directors consists of nine directors.


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.

        SDTB.    Under the CGCL, any or all of the directors may be removed without cause if the removal is approved by a vote of the holders of a majority of the outstanding shares, subject to certain limitations. The CGCL also provides that any director may be removed by a court for fraudulent or dishonest acts, or gross abuse of authority, if shareholders holding at least ten percent of the number of outstanding shares of any class bring suit.


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.

        SDTB.    Under the CGCL and the SDTB bylaws, except for a vacancy created by the removal of a director, any vacancy on the board of directors may be filled by the affirmative vote of a majority of the remaining directors, by the unanimous written consent of the directors then in office (even if less than a quorum of the board), or by a sole remaining director. Any vacancy resulting from the removal of a director by the shareholders may be filled only by the shareholders. If shareholders elect a director by written consent, other than to fill a vacancy created by removal, the consent of a majority of the outstanding shares entitled to vote is required. Each director chosen to fill a vacancy will hold office for the unexpired term of the director's predecessor in office.


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

129


Table of Contents

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 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 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 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 stockholders.

        The DGCL 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.

        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 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 Pacific Premier or its 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.

        SDTB.    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.

        The CGCL provides that indemnification is mandatory if the agent is successful on the merits in defense of such a proceeding. Where it is not mandatory, indemnification may be made only if

130


Table of Contents

authorized in the specific case by (i) a majority vote of a quorum of directors who are not parties to the proceeding, (ii) if such a quorum is not obtainable, independent legal counsel in a written opinion, (iii) approval of the shareholders (other than a shareholder seeking indemnification), or (iv) a court.

        Under 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. The SDTB articles of incorporation provide that SDTB is authorized to indemnify its agents to the fullest extent permissible under California law through bylaw provisions, agreements with its agents, approval by its shareholders or disinterested directors, or otherwise, in excess of the indemnification otherwise permitted by Section 317 of the CGCL, subject to the limitations set forth in Section 204 of the CGCL, and to the requirements of federal laws, rules, regulations or orders requiring indemnification and prepayment of legal expenses, including Section 18(k) of the Federal Deposit Insurance Act and part 359 of the rules and regulations of the Federal Deposit Insurance Corporation or any successor regulations thereto.

        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 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, or (vi) 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 SDTB articles of incorporation and the SDTB bylaws eliminate the liability of the directors of SDTB 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 also may be amended by the affirmative vote of the holders of at least 662/3% of the voting power of all of the

131


Table of Contents

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.

        SDTB.    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.

        Under the SDTB bylaws, the bylaws may be amended by the vote or written consent of SDTB shareholders entitled to exercise a majority of the voting power of the corporation. The SDTB bylaws also authorize SDTB's board of directors to amend its bylaws, provided that a bylaw specifying or changing a fixed number of directors or the maximum or minimum number, or changing from a fixed to a variable board or vice versa may only be adopted by the vote or written consent of shareholders entitled to exercise a majority of the voting power of the corporation.


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.

        SDTB.    In accordance with the CGCL, the SDTB bylaws provide that a written notice of the place, the date and the hour of all shareholder meetings must be sent to each shareholder entitled to vote at the meeting not less than ten (10) (or if sent by third-class mail, thirty (30)) nor more than sixty (60) days prior to the meeting.


Special Meetings of Shareholders

        Pacific Premier.    Under 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.

        SDTB.    Under the CGCL, special meetings of the shareholders may be called by the board, the chairperson of the board, the president, the holders of shares entitled to cast not less than ten percent of the votes at the meeting, or any additional persons as may be provided in the articles or bylaws. The SDTB bylaws provide that special meetings of shareholders may be called at any time by the SDTB board of directors, chairman, vice chairman or president, or by the holders of shares entitled to case not less than ten percent of the votes at the meeting.


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

132


Table of Contents

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 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.

        SDTB.    Neither the CGCL, the SDTB articles of incorporation nor the SDTB bylaws specifically address shareholder nominations or 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.

        SDTB.    Under SDTB's bylaws, any action which may be taken at any annual or special meeting of the shareholders may be taken without a meeting and without prior notice, if a consent in writing, setting forth the action so taken, is signed by the holders of shares representing not less than the minimum number of votes that would have been necessary to take such action at a meeting at which the holders of all shares entitled to vote on the action were present and voted. Directors may not be elected by written consent except by unanimous written consent of all shares entitled to vote for the election of directors.


Transactions with Interested Persons

        Pacific Premier.    The DGCL prohibits a corporation from engaging in any business combination with an interested stockholder (defined as a 15% stockholder) for a period of three years after the date that stockholder became an interested stockholder, unless (i) before that date, the board of directors of the corporation approved the business combination or the transaction in which the stockholder became an interested stockholder, (ii) upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the stockholder 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 stockholder became an interested stockholder, 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 stockholder 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 stockholders.

        SDTB.    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

133


Table of Contents

transaction, if: (i) the material facts as to the transaction and as to such director's interest are fully 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; or (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 its 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.

        SDTB.    Because SDTB is a bank, the CGCL restrictions on dividends do not apply to SDTB pursuant to the California Financial Code. However, under the California Financial Code, SDTB is restricted from paying a dividend except in the following circumstances: (i) without the consent of either the CA DFI or SDTB's shareholders, in an amount not exceeding the lesser of (a) the retained earnings of SDTB or (b) the net income of SDTB for its last three fiscal years (less any distributions to shareholders made during such period); (ii) with the prior approval of CA DFI, in an amount not exceeding the greatest of: (x) the retained earnings of SDTB; (y) the net income of SDTB for its last fiscal year; or (z) the net income for SDTB for its current fiscal year; (iii) with the prior approval of CA DFI by redeeming its redeemable shares, and (iv) with the prior approval of CA DFI and SDTB's shareholders in connection with a reduction of its contributed capital. Finally, under federal law, SDTB is prohibited from paying any dividends if after making such payment it would fail to meet any of its minimum regulatory capital requirements.


Shareholders' Right of Dissent and Appraisal

        Pacific Premier.    Under the DGCL, stockholders are generally entitled to dissent from 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.

134


Table of Contents

        SDTB.    SDTB's shareholders are entitled to dissenters' rights in connection with the merger under the CGCL. For a discussion of the dissenters' rights under the CGCL, see "The Merger—Dissenters' Rights" beginning on page 88, and the dissenters' rights provisions of the CGCL, a copy of which is attached as Appendix C to this proxy statement/prospectus.


ADJOURNMENT OF THE SPECIAL MEETING
(PROPOSAL TWO)

        In the event there are not sufficient votes at the time of the special meeting to constitute a quorum or approve the merger agreement, then the SDTB board of directors may propose to adjourn the special meeting to a later date or dates in order to permit the solicitation of additional proxies. Pursuant to the CGCL and SDTB's bylaws, the SDTB board of directors is not required to fix a new record date to determine the shareholders entitled to vote at the adjourned meeting unless the adjourned meeting is scheduled for a date that is more than 45 days from the date of the special meeting. If the SDTB board of directors does not fix a new record date, it is not necessary to give any notice of the time and place of the adjourned meeting other than an announcement at the meeting at which the adjournment is taken, unless the adjournment is for more than forty-five (45) days. If a new record date is fixed, notice of the adjourned meeting shall be given as in the case of the special meeting.

        In order to permit proxies that have been received by SDTB at the time of the special meeting to be voted for an adjournment, if necessary, SDTB has submitted this proposal as a separate matter for consideration by SDTB shareholders, which is referred to as the adjournment proposal. If approved, the adjournment proposal will authorize the holder of any proxy solicited by the SDTB board of directors to vote in favor of adjourning the special meeting and any later adjournments. If the SDTB shareholders approve this adjournment proposal, SDTB could adjourn the special meeting and use the additional time to solicit additional proxies to gain a quorum for the special meeting or approve the merger agreement, including the solicitation of proxies from SDTB shareholders who have previously voted against the merger agreement. Among other things, approval of the adjournment proposal could mean that, even if proxies representing a sufficient number of votes against merger agreement have been received, SDTB could adjourn the special meeting without a vote on the proposal to approve the merger agreement and seek to convince the holders of those shares to change their votes to votes in favor of the proposal to approve the merger agreement.


Vote Required

        The affirmative vote of the holders of a majority of the shares of SDTB common stock represented and voting at the special meeting, which shares voting affirmatively must also constitute at least a majority of the required quorum, is needed to approve the adjournment proposal. Abstentions and broker non-votes of shares of SDTB common stock will not have any effect on the adjournment proposal, if the number of affirmative votes cast for this proposal is a majority of the votes cast and such votes also constitute a majority of the quorum required to transact business at the special meeting. 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 SDTB board of directors to adjourn the special meeting. Unless instructions to the

135


Table of Contents

contrary are specified with respect to the proposal where a proxy is signed and returned, such proxies will be voted "FOR" this proposal.


THE SDTB BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
THAT SDTB SHAREHOLDERS VOTE "FOR" THE ADJOURNMENT PROPOSAL.


LEGAL MATTERS

        The validity of the Pacific Premier common stock to be issued in the merger has been passed upon for Pacific Premier by Patton Boggs LLP, Washington, DC. As of May 9, 2013, attorneys employed by that law firm beneficially owned approximately 39,000 shares of Pacific Premier common stock.

INDEPENDENT AUDITOR'S REPORT

Board of Directors and Shareholders of
San Diego Trust Bank

We have audited the accompanying financial statements of San Diego Trust Bank, which are comprised of the statements of financial condition as of December 31, 2012 and 2011, and the related statements of income, comprehensive income, changes in shareholders' equity and cash flows for the years then ended, and the related notes to the financial statements.


Management's Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.


Auditor's Responsibility

Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor's judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity's preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity's internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.


Opinion

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of San Diego Trust Bank as of December 31, 2012 and 2011, and the results of its operations and its cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

SAN DIEGO TRUST BANK

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2012 AND 2011

NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

The Bank has been organized as a single operating segment and operates three full-service offices in the San Diego California metropolitan area. The Bank's primary source of revenue is from investment securities and also from providing loans to customers, who are predominately small and middle-market businesses and individuals.

Subsequent Events

The Bank has evaluated subsequent events for recognition and disclosure through January 24, 2013, which is the date the financial statements were available to be issued.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

For purposes of reporting cash flows, cash and cash equivalents include cash, due from banks and federal funds sold. Generally, federal funds are sold for one-day periods.

Cash and Due from Banks

Banking regulations require that banks maintain a percentage of their deposits as reserves in cash or on deposit with the Federal Reserve Bank. The Bank complied with the reserve requirements as of December 31, 2012.

The Bank maintains amounts due from banks, which may exceed federally insured limits. The Bank has not experienced any losses in such accounts.

Investment Securities

Bonds, notes, and debentures for which the Bank has the positive intent and ability to hold to maturity are reported at cost, adjusted for premiums and discounts that are recognized in interest income using the interest method over the period to maturity. Investments not classified as trading securities nor as held-to-maturity securities are classified as available-for-sale securities and recorded at fair value. Unrealized gains or losses on available-for-sale securities are excluded from net income and reported as an amount net of taxes as a separate component of other comprehensive income included in shareholders' equity.

Premiums or discounts on held-to-maturity and available-for-sale securities are amortized or accreted into income using the interest method. Realized gains or losses on sales of held-to-maturity or available-for-sale securities are recorded on the trade date using the specific identification method.

SAN DIEGO TRUST BANK

NOTES TO FINANCIAL STATEMENTS (Continued)

DECEMBER 31, 2012 AND 2011

NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Management evaluates securities for other-than-temporary impairment ("OTTI") on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings.

Loans

Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balances reduced by any charge-offs or specific valuation accounts and net of any deferred fees or costs on originated loans, or unamortized premiums or discounts on purchased loans.

Loan origination fees and certain direct origination costs are deferred and recognized in interest income using the level-yield method without anticipating prepayments.

Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. The accrual of interest on loans is discontinued when principal or interest is past due 90 days or when, in the opinion of management, there is reasonable doubt as to collectibility based on contractual terms of the loan. When loans are placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Income on nonaccrual loans is subsequently recognized only to the extent that cash is received and the loan's principal balance is deemed collectible. Interest accruals are resumed on such loans only when they are brought current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to all principal and interest.

Allowance for Loan Losses

The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management's judgment, should be charged off. Amounts are charged-off when available information confirms that specific loans or portions thereof, are uncollectible. This methodology for determining charge-offs is consistently applied to each portfolio segment.

DECEMBER 31, 2012 AND 2011

NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

The Bank determines a separate allowance for each portfolio segment. The allowance consists of specific and general reserves. Specific reserves relate to loans that are individually classified as impaired. A loan is impaired when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement or when a loan is determined to be a troubled debt restructuring as explained further below. Factors considered in determining impairment include payment status, collateral value and the probability of collecting all amounts when due. Measurement of impairment is based on the expected future cash flows of an impaired loan, which are to be discounted at the loan's effective interest rate, or measured by reference to an observable market value, if one exists, or the fair value of the collateral for a collateral-dependent loan. The Bank selects the measurement method on a loan-by-loan basis except that collateral-dependent loans are measured at the fair value of the collateral.

The Bank recognizes interest income on impaired loans based on its existing methods of recognizing interest income on nonaccrual loans. Loans, for which the terms have been modified resulting in a concession, and for which the borrower is experiencing or has experienced financial difficulties, are considered troubled debt restructurings and classified as impaired with measurement of impairment as described above.

If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan's existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Smaller balance, homogeneous loans are collectively evaluated for impairment.

General reserves cover non-impaired loans and are based on historical loss rates for each portfolio segment, or industry data when no loss experience exists, adjusted for the effects of qualitative or environmental factors that are likely to cause estimated credit losses as of the evaluation date to differ from the portfolio segment's historical loss experience. Qualitative factors include consideration of the following: changes in lending policies and procedures; changes in economic conditions, changes in the nature and volume of the portfolio; changes in the experience, ability and depth of lending management and other relevant staff; changes in the volume and severity of past due, nonaccrual and other adversely graded loans; changes in the loan review system; changes in the value of the underlying collateral for collateral-dependent loans; concentrations of credit and the effect of other external factors such as competition and legal and regulatory requirements.

Portfolio segments identified by the Bank include construction and land development, commercial real estate, residential real estate, commercial and industrial and consumer loans. Relevant risk characteristics for these portfolio segments generally include debt service coverage, loan-to-value ratios and financial performance on non-consumer loans and credit history, debt-to-income, collateral type and loan-to-value ratios for consumer loans.

Premises and Equipment

Premises and equipment are carried at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives, which ranges from three to seven years for furniture and equipment. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the improvements or the remaining lease

term, whichever is shorter. Expenditures for betterments or major repairs are capitalized and those for ordinary repairs and maintenance are charged to operations as incurred.

Other Real Estate Owned

Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed.

Bank Owned Life Insurance

Bank owned life insurance is recorded at the amount that can be realized under insurance contracts at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.

Federal Home Loan Bank ("FHLB") Stock

The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and is periodically evaluated for impairment.

Transfers of Financial Assets

Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Bank, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Bank does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.

Income Taxes

Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. Tax effects from an uncertain tax position are recognized in the financial statements only if, based on its merits, the position is more likely than not to be sustained on audit by the taxing authorities. Interest and penalties related to uncertain tax positions are recorded as part of income tax expense.

Comprehensive Income

The change in unrealized gains and losses on available-for-sale securities is the only component of accumulated other comprehensive income for the Bank.

Financial Instruments

In the ordinary course of business, the Bank has entered into off-balance sheet financial instruments consisting of commitments to extend credit, commercial letters of credit, and standby letters of credit as described in Note J. Such financial instruments are recorded in the financial statements when they are funded or related fees are incurred or received.

Earnings per Share ("EPS")

Basic EPS excludes dilution and is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if options or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. The Bank issued a 3% stock dividend in 2012 and 2011. The per share data in the Statements of Income and accompanying footnotes have been adjusted to give retroactive effect to this dividend to the beginning of each fiscal year.

Stock-Based Compensation

Compensation cost is recognized for stock options issued to employees, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options. This cost is recognized over the period which an employee is required to provide services in exchange for the award, generally defined as the vesting period.

Fair Value Measurement

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Current accounting guidance establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair values:

See Note N for more information and disclosures relating to the Bank's fair value measurements.

Reclassifications

Certain reclassifications have been made in the 2011 financial statements to conform to the presentation used in 2012. These reclassifications had no impact of the Bank's previously reported financial statements.

Adoption of New Accounting Standards

In May 2011, the FASB issued an amendment to achieve common fair value measurement and disclosure requirements between U.S. and International accounting principles. Overall, the guidance is consistent with existing U.S. accounting principles; however, there are some amendments that change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements. The amendment in this guidance was effective for interim and annual reporting periods beginning after December 15, 2011. The amendment did not significantly impact the Bank.

In September 2011, the FASB amended existing guidance and eliminated the option to present the components of other comprehensive income as part of the statement of changes in shareholders' equity. The amendment requires that comprehensive income be presented in either a single continuous statement or in two separate consecutive statements. This amendment was effective for interim and annual reporting periods beginning after December 15, 2011. The adoption of this amendment changed the presentation of comprehensive income in these financial statements.

All mortgage-backed securities owned by the Bank at December 31, 2012 and 2011, were issued by U.S. Government agencies or Government Sponsored entities which carry either the explicit or implicit guarantee of the United States Government.

All Corporate Bonds are of companies which are Fortune 100 corporations and are rated A- or above by Standard & Poors. Municipal Bonds are all rated AA or higher by Standard & Poors or Moody's and additionally, carry insurance issued by the top rated municipal bond insurer in the nation or are guaranteed by specific funds by the individual states.

During 2012 and 2011, the Bank received proceeds of $8,323,499 and $2,810,796 from the sale of securities and recognized gross gains of $422,569 and $226,692 and gross losses of $0 and $0, respectively.

As of December 31, 2012 and 2011, no security had been in a continuous loss position for a period of more than twelve consecutive months. Unrealized losses have not been recognized into income because the issuer bonds are of high credit quality, management does not intend to sell and it is not more likely than not that management would be required to sell the securities prior to their anticipated recovery, and the decline in fair value is largely due to changes in interest rates and investor sentiment.

Securities with a fair value of approximately $63.5 million at December 31, 2012, were pledged to the Federal Home Loan Bank to secure borrowings as discussed in Note G.

NOTE C—LOANS

The Bank's loan portfolio consists primarily of loans to borrowers within San Diego County, California. Although the Bank seeks to avoid concentrations of loans to a single industry or based upon a single class of collateral, real estate and real estate associated businesses are among the principal industries in the Bank's market area and, as a result, the Bank's loan and collateral portfolios are, to some degree, concentrated in those industries.

The Bank has pledged loans with a carrying value of approximately $7.2 million to secure a line of credit with the Federal Home Loan Bank as discussed in Note G.

collateral adequacy, credit documentation, and current economic trends, among other factors. The Bank analyzes loans individually by classifying the loans as to credit risk. This analysis typically includes larger, non-homogeneous loans such as commercial real estate and commercial and industrial loans. This analysis is performed on an ongoing basis as new information is obtained. The federal regulatory agencies use the following definitions for risk ratings:

        Pass—Loans classified as pass include loans not meeting the risk ratings defined below.

        Special Mention—Loans classified as special mention have a potential weakness that deserves management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution's credit position at some future date.

        Substandard—Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

        Impaired—A loan is considered impaired, when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement. Additionally, all loans classified as troubled debt restructurings are considered impaired.

The risk category of loans by class of loans is as follows as of December 31, 2012 and 2011:

Deposits from executive officers, directors and their related interests with which they are associated held by the Bank at December 31, 2012 and 2011, amounted to approximately $3,681,000 and $4,003,000, respectively.

NOTE G—OTHER BORROWING

The Bank has a borrowing arrangement with the Federal Home Loan Bank of San Francisco. The Bank can borrow up to approximately $55 million based on its asset size at December 31, 2012 and has pledged approximately $7.2 million of qualifying loans and $63.5 million of securities relating to this arrangement. As of December 31, 2012, the Bank had borrowed $25 million under this arrangement which is due on January 3, 2013, bearing interest at .26%

The Bank may also borrow up to $9 million on an unsecured basis from two correspondent banks. As of December 31, 2012, no amounts were outstanding and no assets had been pledged under these arrangements.

NOTE H—INCOME TAXES

The asset and liability method is used in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

  $ 1,423,901   $ 1,460,118  
           

NOTE J—COMMITMENTS

In the ordinary course of business, the Bank enters into financial commitments to meet the financing needs of its customers. These financial commitments include commitments to extend credit and standby letters of credit. Those instruments involve to varying degrees, elements of credit and interest rate risk not recognized in the Bank's financial statements.

The Bank's exposure to loan loss in the event of nonperformance on commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Bank uses the same credit policies in making commitments as it does for loans reflected in the financial statements. As of December 31, the Bank had the following outstanding financial commitments whose contractual amount represents credit risk:

 
  2012   2011  

Commitments to Extend Credit

  $ 5,378,566   $ 5,418,801  
           

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the total amounts do not necessarily represent future cash requirements. The Bank evaluates each client's credit worthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by the Bank is based on management's credit evaluation of the customer.

The Bank has purchased life insurance on several key executives to which the Bank is the sole beneficiary of such policies. The tax-free income generated from these policies is utilized to offset the costs of employee benefits, including, but not limited to health insurance premiums, workers' compensation insurance, and 401k expense. A portion is also being accrued in contemplation of certain supplemental retirement agreements that have been entered into with certain key executives.

The amounts due under such agreements vary greatly, are generally payable at age 65, are payable over a ten-year period, and are subject to achieving certain vesting requirements. The estimated present value of future benefits to be paid is being accrued over the period from the effective date of the agreements until the expected retirement dates of the participants. The amounts accrued as of December 31, 2012 and 2011, were $621,190 and $475,860, respectively. Expense recognized relating to supplemental retirement agreements was $182,882 and $144,700 for 2012 and 2011, respectively.

NOTE L—STOCK OPTION PLAN

Under the terms of the 2003 Stock Plan (as amended and restated in 2011), officers and key employees may be granted both nonqualified and incentive stock options and directors and other consultants, who are not also an officer or employee, may only be granted nonqualified stock options. The Plan provides for options to grant up to 778,701 shares of common stock at a price not less than 100 percent of the fair market value of the stock on the date of grant, of which 40,756 are still available for issuance as of December 31, 2012. Stock options expire no later than ten years from the date of the grant.

No options were granted in 2011. The fair value of each option granted in 2012 was estimated on the date of the grant using the Black-Scholes option pricing model with the following weighted average assumptions:

 
  2012  

Risk Free Interest Rate

    0.80 %

Estimated Average Life

    4.5 Years  

Expected Dividend Rates

    0.00 %

Expected Stock Volatility

    10.00 %

Weighted-Average Option Value

  $ 1.28  

The Bank recognized stock-based compensation expense of $71,640 and $73,309 and income tax benefits on that expense of approximately $11,600 and $8,700 in 2012 and 2011, respectively.

    327,989   $ 9.63   3.0 Years   $ 1,498,637  
                   

The total intrinsic value of options exercised during the years ended December 31, 2012 and 2011 was $24,200 and $773,000, respectively. As of December 31, 2012, there was approximately $116,000 of total unrecognized compensation cost related to outstanding stock options that will be recognized over a weighted average period of 1.5 years.

Out of 65,770 shares exercised in 2011, 59,270 were exercised on a cashless net settlement basis, which is permitted under the 2003 Plan as amended. In these exercise transactions option holders are not required to tender cash payment for shares purchased, but rather have the Bank issue to them fewer shares than the number of options being exercised with reductions in the shares issued to cover the cost to exercise the shares and the amount of tax withholding payments required to be made by the Bank on behalf of the option holder. In 2011, the Bank issued 20,555 shares to satisfy the cashless exercises of 59,270 option shares.

NOTE M—REGULATORY MATTERS

The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements could initiate certain mandatory—and possibly additional discretionary—actions by regulators that, if undertaken, could have a direct material effect on the Bank's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank's assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. The Bank has never been subject to any regulatory order since inception.

Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table below) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). Management believes, as of December 31, 2012, that the Bank meets all capital adequacy requirements to which it is subject. As of December 31, 2012, the most recent notification from the Federal Deposit Insurance Corporation (the "FDIC") categorized the Bank as

The California Financial Code provides that a bank may not make cash distribution to its shareholders in excess of the lesser of the Bank's undivided profits or the Bank's net income for its last three fiscal years less the amount of any distribution made by the Bank to shareholders during the same period.

NOTE N—FAIR VALUE MEASUREMENT

The following is a description of valuation methodologies used for assets and liabilities recorded at fair value:

Securities:    The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1) or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for specific securities but rather by relying on the securities' relationship to other benchmark quoted securities (Level 2).

Other Real Estate Owned:    The fair value of other real estate owned is generally based on recent real estate appraisals or broker opinions, obtained from independent third parties, which are frequently adjusted by management to reflect current conditions and estimated selling costs (Level 3).

NOTE O—FAIR VALUE OF FINANCIAL INSTRUMENTS

The fair value of a financial instrument is the amount at which the asset or obligation could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the entire holdings of a particular financial instrument. Because no market value exists for a significant portion of the financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature, involve uncertainties and matters of judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Fair value estimates are based on financial instruments both on and off the balance sheet without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Additionally, tax consequences related to the realization

NOTES TO FINANCIAL STATEMENTS (Continued)

DECEMBER 31, 2012 AND 2011

NOTE O—FAIR VALUE OF FINANCIAL INSTRUMENTS (Continued)

of the unrealized gains and losses can have a potential effect on fair value estimates and have not been considered in many of the estimates.

The following methods and assumptions were used to estimate the fair value of significant financial instruments:

Financial Assets

The carrying amounts of cash, short term investments, due from customers on acceptances, and Bank acceptances outstanding are considered to approximate fair value. Short term investments include federal funds sold, securities purchased under agreements to resell, and interest bearing deposits with Banks. The fair values of investment securities, including available for sale, are generally based on quoted market prices. The fair value of loans are estimated using a combination of techniques, including discounting estimated future cash flows and quoted market prices of similar instruments where available.

Financial Liabilities

The carrying amounts of deposit liabilities payable on demand, commercial paper, and other borrowed funds are considered to approximate fair value. For fixed maturity deposits, fair value is estimated by discounting estimated future cash flows using currently offered rates for deposits of similar remaining maturities. The fair value of long term debt is based on rates currently available to the Bank for debt with similar terms and remaining maturities.

Off-Balance Sheet Financial Instruments

The fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements. The fair value of these financial instruments is not material.

The fair value hierarchy level and estimated fair value of significant financial instruments at December 31, 2012 and 2011 are summarized as follows (dollar amounts in thousands):

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 SDTB shareholders, no amendment shall be made which by law requires further approval by the shareholders of SDTB 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 SDTB, the approval of the principal terms of this Agreement by the SDTB shareholders will be deemed to have granted SDTB the authority to amend such dates without such further approval.

        9.03    Counterparts.    This Agreement may be executed in one or more counterparts, each of which shall be deemed to constitute an original.

        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.

        9.05    Expenses.    Each party hereto will bear all expenses incurred by it in connection with this Agreement and the transactions contemplated hereby (the "Deal Expenses"), provided that SDTB's Deal Expenses, which shall include the items set forth in Section 9.05 of SDTB's Disclosure Schedule, on an after Tax equivalent basis, shall not exceed $3,000,000, provided that if they do and subject to the next sentence, such will not be deemed a breach of this Agreement, and PPBI shall pay at Closing SDTB's Deal Expenses not paid prior to Closing, including expenses relating to legal, accounting and advisory (including the fee payable to Keefe, Bruyette, & Woods, Inc.). To the extent that SDTB's aggregate Deal Expenses (whether paid by SDTB prior to Closing or by PPBI at Closing), on an after Tax equivalent basis, exceed $3,000,000, any excess shall reduce the Per Share Cash Consideration by the quotient of (i) such excess divided by (ii) the total number of shares of issued and outstanding SDTB Common Stock. For purposes of this Agreement, "Deal Expenses" shall not include any costs or expenses incurred or accrued by SDTB in connection with or arising out of: (i) any litigation, arbitration, claim or other proceeding before any court or Governmental Authority that is brought against SDTB by a third-party and arising out of or in connection with this Agreement or the Transaction; (ii) any retention payments made or to be made to employees of SDTB; (iii) the acceleration of SDTB Stock Options; and/or (iv) obtaining the insurance policy as provided in Section 6.10(c), except for the costs and expenses for such policy in excess of the Maximum Insurance Amount, which excess amount shall be considered part of and included in "Deal Expenses."

        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

A-54


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.

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 SDTB 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

A-55


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.

        9.09    Enforcement of the Agreement.    The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. 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 SDTB set forth herein, provided that (i) the Merger Consideration to be paid to the holders of SDTB 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 SDTB's shareholders as a result of receiving the Merger Consideration and (iii) such modification will not materially 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 (the "Agreement"), dated as of March 5, 2013, among                     , a shareholder ("Shareholder") of San Diego Trust Bank, a California bank ("SDTB"), Pacific Premier Bancorp, Inc., a Delaware corporation ("PPBI"), and, solely for purposes of the last sentence of Section 9, SDTB. All terms used herein and not defined herein shall have the meanings assigned thereto in the Merger Agreement (defined below).

        WHEREAS, SDTB, PPBI and Pacific Premier Bank, PPBI's wholly-owned bank subsidiary ("Pacific Premier"), are entering into an Agreement and Plan of Reorganization, dated as of the date hereof (the "Merger Agreement"), pursuant to which SDTB will be acquired by Pacific Premier on the terms and conditions set forth therein (the "Merger") and, in connection therewith, outstanding shares of SDTB Common Stock will be converted into shares of PPBI Common Stock and/or cash in the manner set forth therein; and

        WHEREAS, Shareholder owns the shares of SDTB Common Stock identified on Exhibit I hereto (such shares, together with all shares of SDTB 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 and Pacific Premier to enter into the Merger Agreement, Shareholder, solely in such Shareholder's capacity as a shareholder of SDTB 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 SDTB, or in connection with any written consent of the shareholders of SDTB, Shareholder shall:

        2.    Transfer of Shares.    

A-A-1


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

A-A-2


        4.    No Solicitation.    Shareholder hereby agrees that during the term of this Agreement he, she or it shall not, and shall not knowingly 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 SDTB, 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 SDTB 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 SDTB 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 SDTB 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 SDTB Common Stock or other securities of SDTB 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 SDTB.

        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.

        8.    Term of Agreement; Termination.    

        9.    Stop Transfer Order.    In furtherance of this Agreement, Shareholder hereby authorizes and instructs SDTB to enter a stop transfer order with respect to all of Shareholder's Shares for the period from the date hereof through the date this Agreement is terminated in accordance with Section 8. SDTB agrees that it shall comply with such stop transfer instructions.

A-A-4


        10.    Entire Agreement.    This Agreement supersedes all prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof. 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. No waiver of any provisions hereof by any party shall be deemed a waiver of any other provisions hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

March 5, 2013

The Board of Directors
San Diego Trust Bank
2550 Fifth Avenue, Suite 1010
San Diego, CA 92103

Members of the Board:

        You have requested our opinion as investment bankers as to the fairness, from a financial point of view, to the common stockholders of San Diego Trust Bank ("SDBK"), of the Aggregate Merger Consideration (as defined in the Agreement) in the proposed merger (the "Merger") of SDBK with Pacific Premier Bank, a wholly-owned subsidiary of Pacific Premier Bancorp, Inc. a Delaware corporation ("PPBI"). The terms of the Merger are set forth in the draft Agreement and Plan of Reorganization, dated as of March 1, 2013, among PPBI, Pacific Premier Bank and SDBK (the "Agreement"). Pursuant to the terms of the Agreement, each share of common stock, no par value, of SDBK not owned by SDBK and PPBI or by any of the respective wholly-owned subsidiaries (other than shares owned in a fiduciary capacity or as a result of debts previously contracted) issued and outstanding immediately prior to the Merger will be cancelled and retired and converted into the right to receive Per Share Stock Consideration or Per Share Cash Consideration, subject to adjustments as described in the Agreement. The terms and conditions of the Merger are more fully described in the Agreement.

        Keefe, Bruyette & Woods, Inc., has acted as financial advisor to SDBK and not as an advisor to or agent of any other person. As part of our investment banking business, we are continually engaged in the valuation of bank and bank holding company securities in connection with acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for various other purposes. As specialists in the securities of banking companies, we have experience in, and knowledge of, the valuation of banking enterprises. In the ordinary course of our business as a broker-dealer, we may, from time to time purchase securities from, and sell securities to, SDBK and PPBI, and as a market maker in securities, we may from time to time have a long or short position in, and buy or sell, debt or equity securities of SDBK and PPBI for our own account and for the accounts of our customers. To the extent we have any such position as of the date of this opinion it has been disclosed to SDBK. We have acted exclusively for the Board of Directors of SDBK in rendering this fairness opinion and will receive a fee from SDBK for our services. A portion of our fee is contingent upon the successful completion of the Merger.

        During the past two years, we have not provided any investment banking and financial advisory services to SDBK or received compensation for such services. We also have not provided investment banking and financial advisory services to PPBI in the past two years. We may in the future seek to provide investment banking and financial advisory services to PPBI and receive compensation for such services.

        In connection with this opinion, we have reviewed, analyzed and relied upon material bearing upon the financial and operating condition of SDBK and PPBI and the Merger, including among other things, the following: (i) a draft of the Agreement dated March 1, 2013 (the most recent draft made available to us); (ii) the Annual Reports to Stockholders and Annual Reports on Form 10-K for the three fiscal years ended December 31, 2011, and certain interim reports to stockholders and Quarterly

Reports on Form 10-Q for PPBI; (iii) the Annual and Quarterly Filings with the Federal Deposit Insurance Corporation for the three fiscal years ended December 31, 2012 for SDBK; and (iv) certain interim reports and other communications to stockholders and other financial information concerning the businesses and operations of SDBK and PPBI, furnished to us by SDBK and PPBI for purposes of our analysis. We have also held discussions with senior management of SDBK and PPBI regarding the past and current business operations, regulatory relations, financial condition and future prospects of their respective companies and such other matters as we have deemed relevant to our inquiry. In addition, we have compared certain financial and stock market information for SDBK and PPBI with similar information for certain other companies the securities of which are publicly traded, and reviewed the financial terms of certain recent business combinations in the banking industry and performed such other studies and analyses as we considered appropriate.

        In conducting our review and arriving at our opinion, we have relied upon the accuracy and completeness of all of the financial and other information provided to us or publicly available and we have not independently verified the accuracy or completeness of any such information or assumed any responsibility for such verification or accuracy. We have relied upon the management of SDBK and PPBI as to the reasonableness and achievability of the financial and operating forecasts and projections (and the assumptions and bases therefore) provided to us, and we have assumed that such forecasts and projections reflect the best currently available estimates and judgments of such managements and that such forecasts and projections will be realized in the amounts and in the time periods currently estimated by such managements. We are not experts in the independent verification of the adequacy of allowances for loan and lease losses and we have assumed, with your consent that the aggregate allowances for loan and lease losses for SDBK and PPBI are adequate to cover such losses. In rendering our opinion, we have not made or obtained any evaluations or appraisals of the property, assets or liabilities of SDBK or PPBI, nor have we examined any individual credit files.

        We have assumed that, in all respects material to our analyses, the following: (i) the Merger will be completed substantially in accordance with the terms set forth in the Agreement (the final terms of which will not differ in any respect material to our analyses from the draft reviewed) with no additional payments or adjustments to the Aggregate Merger Consideration; (ii) the representations and warranties of each party in the Agreement and in all related documents and instruments referred to in the Agreement are true and correct; (iii) each party to the Agreement and all related documents will perform all of the covenants and agreements required to be performed by such party under such documents; (iv) all conditions to the completion of the Merger will be satisfied without any waivers or modifications to the Agreement; and (v) in the course of obtaining the necessary regulatory, contractual, or other consents or approvals for the Merger, no restrictions, including any divestiture requirements, termination or other payments or amendments or modifications, will be imposed that will have a material adverse effect on the future results of operations or financial condition of the combined entity or the contemplated benefits of the Merger, including the cost savings, revenue enhancements and related expenses expected to result from the Merger.

        We have considered such financial and other factors as we have deemed appropriate under the circumstances, including, among others, the following: (i) the historical and current financial position and results of operations of SDBK and PPBI; (ii) the assets and liabilities of SDBK and PPBI; and (iii) the nature and terms of certain other merger transactions involving banks and bank holding companies. We have also taken into account our assessment of general economic, market and financial conditions and our experience in other transactions, as well as our experience in securities valuation and knowledge of the banking industry generally. Our opinion is necessarily based upon conditions as they exist and can be evaluated on the date hereof and the information made available to us through the date hereof. Our opinion does not address the underlying business decision of SDBK to engage in the Merger, or the relative merits of the Merger as compared to any strategic alternatives that may be available to SDBK.

        This opinion addresses only the fairness, from a financial point of view, as of the date hereof, to the holders of the Common Shares of the Aggregate Merger Consideration in the Merger. We express no view or opinion as to any terms or other aspects of the Merger.

        Further, we are not expressing any opinion about the fairness of the amount or nature of the compensation to any of SDBK's officers, directors or employees, or any class of such persons, relative to the compensation to the public shareholders of SDBK in connection with the Merger.

        In addition, this opinion does not in any manner address the prices at which the PPBI common stock will trade following the consummation of the Merger and we express no view or opinion as to how the stockholders of SDBK should vote at the stockholders meeting to be held in connection with the Merger.

        This opinion has been reviewed and approved by our Fairness Opinion Committee in conformity with our policies and procedures established under the requirements of Rule 5150 of the Financial Industry Regulatory Authority.

        Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Aggregate Merger Consideration in the Merger is fair, from a financial point of view, to holders of the SDBK common stock.

Very truly yours,

CALIFORNIA GENERAL CORPORATION LAW
CHAPTER 13: DISSENTERS' RIGHTS

1300.
(a) If the approval of the outstanding shares (Section 152) of a corporation is required for a reorganization under subdivisions (a) and (b) or subdivision (e) or (f) of Section 1201, each shareholder of the corporation entitled to vote on the transaction and each shareholder of a subsidiary corporation in a short-form merger may, by complying with this chapter, require the corporation in which the shareholder holds shares to purchase for cash at their fair market value the shares owned by the shareholder which are dissenting shares as defined in subdivision (b). The fair market value shall be determined as of the day of, and immediately prior to, the first announcement of the terms of the proposed reorganization or short-form merger, excluding any appreciation or depreciation in consequence of the proposed reorganization or short-form merger, as adjusted for any stock split, reverse stock split, or share dividend that becomes effective thereafter.

        (b)   As used in this chapter, "dissenting shares" means shares to which all of the following apply:

        (c)   As used in this chapter, "dissenting shareholder" means the recordholder of dissenting shares and includes a transferee of record.

1301.
(a) If, in the case of a reorganization, any shareholders of a corporation have a right under Section 1300, subject to compliance with paragraphs (3) and (4) of subdivision (b) thereof, to require the corporation to purchase their shares for cash, that corporation shall mail to each of those shareholders a notice of the approval of the reorganization by its outstanding shares (Section 152) within 10 days after the date of that approval, accompanied by a copy of Sections 1300, 1302, 1303, and 1304 and this section, a statement of the price determined by the

        (b)   Any shareholder who has a right to require the corporation to purchase the shareholder's shares for cash under Section 1300, subject to compliance with paragraphs (3) and (4) of subdivision (b) thereof, and who desires the corporation to purchase shares shall make written demand upon the corporation for the purchase of those shares and payment to the shareholder in cash of their fair market value. The demand is not effective for any purpose unless it is received by the corporation or any transfer agent thereof (1) in the case of shares described in subdivision (b) of Section 1300, not later than the date of the shareholders' meeting to vote upon the reorganization, or (2) in any other case, within 30 days after the date on which the notice of the approval by the outstanding shares pursuant to subdivision (a) or the notice pursuant to subdivision (h) of Section 1110 was mailed to the shareholder.

        (c)   The demand shall state the number and class of the shares held of record by the shareholder which the shareholder demands that the corporation purchase and shall contain a statement of what the shareholder claims to be the fair market value of those shares as determined pursuant to subdivision (a) of Section 1300. The statement of fair market value constitutes an offer by the shareholder to sell the shares at that price.

        1302.  Within 30 days after the date on which notice of the approval by the outstanding shares or the notice pursuant to subdivision (h) of Section 1110 was mailed to the shareholder, the shareholder shall submit to the corporation at its principal office or at the office of any transfer agent thereof, (a) if the shares are certificated securities, the shareholder's certificates representing any shares which the shareholder demands that the corporation purchase, to be stamped or endorsed with a statement that the shares are dissenting shares or to be exchanged for certificates of appropriate denomination so stamped or endorsed or (b) if the shares are uncertificated securities, written notice of the number of shares which the shareholder demands that the corporation purchase. Upon subsequent transfers of the dissenting shares on the books of the corporation, the new certificates, initial transaction statement, and other written statements issued therefor shall bear a like statement, together with the name of the original dissenting holder of the shares.

1303.
(a) If the corporation and the shareholder agree that the shares are dissenting shares and agree upon the price of the shares, the dissenting shareholder is entitled to the agreed price with interest thereon at the legal rate on judgments from the date of the agreement. Any agreements fixing the fair market value of any dissenting shares as between the corporation and the holders thereof shall be filed with the secretary of the corporation.

        (b)   Subject to the provisions of Section 1306, payment of the fair market value of dissenting shares shall be made within 30 days after the amount thereof has been agreed or within 30 days after any statutory or contractual conditions to the reorganization are satisfied, whichever is later, and in the case of certificated securities, subject to surrender of the certificates therefor, unless provided otherwise by agreement.

1304.
(a) If the corporation denies that the shares are dissenting shares, or the corporation and the shareholder fail to agree upon the fair market value of the shares, then the shareholder demanding purchase of such shares as dissenting shares or any interested corporation, within six months after the date on which notice of the approval by the outstanding shares (Section 152) or notice pursuant to subdivision (h) of Section 1110 was mailed to the shareholder, but not thereafter, may file a complaint in the superior court of the proper county praying the court to

        (b)   Two or more dissenting shareholders may join as plaintiffs or be joined as defendants in any such action and two or more such actions may be consolidated.

        (c)   On the trial of the action, the court shall determine the issues. If the status of the shares as dissenting shares is in issue, the court shall first determine that issue. If the fair market value of the dissenting shares is in issue, the court shall determine, or shall appoint one or more impartial appraisers to determine, the fair market value of the shares.

1305.
(a) If the court appoints an appraiser or appraisers, they shall proceed forthwith to determine the fair market value per share. Within the time fixed by the court, the appraisers, or a majority of them, shall make and file a report in the office of the clerk of the court. Thereupon, on the motion of any party, the report shall be submitted to the court and considered on such evidence as the court considers relevant. If the court finds the report reasonable, the court may confirm it.

        (b)   If a majority of the appraisers appointed fail to make and file a report within 10 days from the date of their appointment or within such further time as may be allowed by the court or the report is not confirmed by the court, the court shall determine the fair market value of the dissenting shares.

        (c)   Subject to the provisions of Section 1306, judgment shall be rendered against the corporation for payment of an amount equal to the fair market value of each dissenting share multiplied by the number of dissenting shares which any dissenting shareholder who is a party, or who has intervened, is entitled to require the corporation to purchase, with interest thereon at the legal rate from the date on which judgment was entered.

        (d)   Any such judgment shall be payable forthwith with respect to uncertificated securities and, with respect to certificated securities, only upon the endorsement and delivery to the corporation of the certificates for the shares described in the judgment. Any party may appeal from the judgment.

        (e)   The costs of the action, including reasonable compensation to the appraisers to be fixed by the court, shall be assessed or apportioned as the court considers equitable, but, if the appraisal exceeds the price offered by the corporation, the corporation shall pay the costs (including in the discretion of the court attorneys' fees, fees of expert witnesses and interest at the legal rate on judgments from the date of compliance with Sections 1300, 1301 and 1302 if the value awarded by the court for the shares is more than 125 percent of the price offered by the corporation under subdivision (a) of Section 1301).

        1306.  To the extent that the provisions of Chapter 5 prevent the payment to any holders of dissenting shares of their fair market value, they shall become creditors of the corporation for the amount thereof together with interest at the legal rate on judgments until the date of payment, but subordinate to all other creditors in any liquidation proceeding, such debt to be payable when permissible under the provisions of Chapter 5.

        1307.  Cash dividends declared and paid by the corporation upon the dissenting shares after the date of approval of the reorganization by the outstanding shares (Section 152) and prior to payment for the shares by the corporation shall be credited against the total amount to be paid by the corporation therefor.

        1308.  Except as expressly limited in this chapter, holders of dissenting shares continue to have all the rights and privileges incident to their shares, until the fair market value of their shares is agreed upon or determined. A dissenting shareholder may not withdraw a demand for payment unless the corporation consents thereto.

        1309.  Dissenting shares lose their status as dissenting shares and the holders thereof cease to be dissenting shareholders and cease to be entitled to require the corporation to purchase their shares upon the happening of any of the following:

        1310.  If litigation is instituted to test the sufficiency or regularity of the votes of the shareholders in authorizing a reorganization, any proceedings under Sections 1304 and 1305 shall be suspended until final determination of such litigation.

        1311.  This chapter, except Section 1312, does not apply to classes of shares whose terms and provisions specifically set forth the amount to be paid in respect to such shares in the event of a reorganization or merger.

1312.
(a) No shareholder of a corporation who has a right under this chapter to demand payment of cash for the shares held by the shareholder shall have any right at law or in equity to attack the validity of the reorganization or short-form merger, or to have the reorganization or short-form merger set aside or rescinded, except in an action to test whether the number of shares required to authorize or approve the reorganization have been legally voted in favor thereof; but any holder of shares of a class whose terms and provisions specifically set forth the amount to be paid in respect to them in the event of a reorganization or short-form merger is entitled to payment in accordance with those terms and provisions or, if the principal terms of the reorganization are approved pursuant to subdivision (b) of Section 1202, is entitled to payment in accordance with the terms and provisions of the approved reorganization.

        (b)   If one of the parties to a reorganization or short-form merger is directly or indirectly controlled by, or under common control with, another party to the reorganization or short-form merger, subdivision (a) shall not apply to any shareholder of such party who has not demanded payment of cash for such shareholder's shares pursuant to this chapter; but if the shareholder institutes any action to attack the validity of the reorganization or short-form merger or to have the reorganization or short-form merger set aside or rescinded, the shareholder shall not thereafter have any right to demand payment of cash for the shareholder's shares pursuant to this chapter. The court in any action attacking the validity of the reorganization or short-form merger or to have the reorganization or short-form merger set aside or rescinded shall not restrain or enjoin the consummation of the transaction except upon 10 days' prior notice to the corporation and upon a determination by the court that clearly no other remedy will adequately protect the complaining shareholder or the class of shareholders of which such shareholder is a member.

        1313.  A conversion pursuant to Chapter 11.5 (commencing with Section 1150) shall be deemed to constitute a reorganization for purposes of applying the provisions of this chapter, in accordance with and to the extent provided in Section 1159.
