Exhibit 99.3

LETTER OF ELECTION AND TRANSMITTAL
To Accompany Certificates for Shares of Common Stock
of
SAN DIEGO TRUST BANK

San Diego Trust Bank ("SDTB") entered into an Agreement and Plan of Reorganization, dated as of March 5, 2013 (the "Merger Agreement"), with Pacific Premier Bancorp, Inc. ("Pacific Premier") and Pacific Premier Bank ("Pacific Premier Bank"), which provides for the merger of SDTB with and into Pacific Premier Bank, with Pacific Premier Bank as the surviving institution (the "Merger"). This Letter of Election and Transmittal is being sent to SDTB shareholders in accordance with the Merger Agreement for the purpose of providing SDTB shareholders with the opportunity to elect the form of, and to receive, their aggregate Merger Consideration (as hereinafter defined). Pursuant to the Merger Agreement, shareholders of SDTB may elect to receive cash, shares of Pacific Premier common stock, or a combination of both in exchange for their shares of SDTB common stock upon consummation of the Merger. The election is subject to allocation procedures 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, with the remaining 50% of the aggregate Merger Consideration to be paid in cash, as set forth in the Merger Agreement.

Pursuant to the Merger Agreement, the undersigned hereby surrenders to American Stock Transfer & Trust Company, LLC, as the exchange agent (the "Exchange Agent"), the undersigned's stock certificate(s) (the "Certificate(s)") representing shares of SDTB common stock (the "Shares") in exchange for the "Merger Consideration," which, for each Share surrendered, consists of:

•: Cash consideration: $13.41 in cash, without interest, subject to downward adjustment if SDTB's aggregate transaction-related expenses exceed $3.0 million, on an after-tax equivalent basis; or
•: Stock consideration: 1.114 of a share of Pacific Premier common stock, 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, as set forth in the Merger Agreement; or
•: A combination of cash consideration and stock consideration.

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.

Because the cash and stock portions of the Merger Consideration are subject to adjustment, the aggregate amount of the Merger Consideration will not be known until the closing date of the Merger. For additional information about the Merger and the Merger Consideration, you should carefully read the proxy statement/prospectus mailed to you on or about [ ], 2013, which is part of Pacific Premier's registration statement on Form S-4 filed with the Securities and Exchange Commission.

This Letter of Election and Transmittal must accompany the Certificate(s) representing your Shares in order to exchange those Shares for the Merger Consideration. See Instructions on the reverse side.

The undersigned hereby represents and warrants that the undersigned has full power and authority to surrender the Certificate(s) surrendered hereby and that the Shares represented by such Certificate(s) are free and clear of all liens, restrictions, charges and encumbrances and that, upon payment therefor in accordance with this Letter of Election and Transmittal, Pacific Premier will not be subject to any adverse claim in respect of such surrendered Certificate(s). The undersigned, upon request, will execute and deliver any additional documents deemed by the Exchange Agent or Pacific Premier to be necessary or desirable in connection with the surrender of the Certificate(s).

Pursuant to the Merger Agreement, the undersigned encloses herewith and surrenders the following Certificate(s):

If an election is not properly made, the tendered Shares will be deemed to have been tendered without an election. Any election (whether actual or deemed) or tender of Share(s) may be withdrawn or changed by written notice to the Exchange Agent only if such written notice is actually received by the Exchange Agent at or prior to the Election Deadline.

8. Letter of Election and Transmittal Required; Surrender of Certificate(s); Lost Certificate(s): You will not receive your shares of Pacific Premier common stock or check(s) for the cash portion of the Merger Consideration unless and until you deliver this Letter of Election and Transmittal, properly completed and duly executed, to the Exchange Agent, together with the Certificate(s) and any required accompanying evidences of authority. If your Certificate(s) has (have) been lost, stolen, misplaced or destroyed, contact the Exchange Agent for instructions at (000) 000-0000 or (000) 000-0000 prior to submitting your Certificate(s) for exchange. Any SDTB shareholder who has lost any Certificate(s) should make arrangements (which may include the posting of a bond or other satisfactory indemnification and an affidavit of loss) to replace the lost Certificate(s). Such arrangements should be made with Exchange Agent.

9. Substitute Form W-9: Under the federal income tax law, a non-exempt shareholder is required to provide the Exchange Agent with such shareholder's correct Taxpayer Identification Number ("TIN") on the enclosed Substitute Form W-9. If the Certificate(s) is (are) in more than one name or is (are) not in the name of the actual owner, consult the enclosed Substitute Form W-9 guidelines for additional guidance on which number to report. Failure to provide the information on the form may subject the surrendering shareholder to 28% backup withholding on the payment of any cash. The surrendering shareholder must check the box in Part 4 if a TIN has not been issued and the shareholder has applied for a number or intends to apply for a number in the near future. If a TIN has been applied for and the Exchange Agent is not provided with a TIN before payment is made, the Exchange Agent will withhold 28% on all payments to such surrendering shareholders of any cash consideration due for their Shares. Please review the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 for additional details on what TIN to give the Exchange Agent.

10. Stock Transfer Taxes. If payment is to be made to any person other than the registered holder, or if the surrendered Certificate(s) is (are) registered in the name of any person other than the person(s) signing the Letter of Election and Transmittal, the amount of any stock transfer taxes (whether imposed on the registered holder or such person) payable as a result of the transfer to such person will be deducted from the payment for such securities if satisfactory evidence of the payment of such taxes, or exemption therefrom, is not submitted. Except as provided in this Instruction 10, it will not be necessary for transfer tax stamps to be affixed to the Certificate(s).

All questions as to the validity, form and eligibility of any surrender of any Certificate(s) will be determined by the Exchange Agent and Pacific Premier and such determination shall be final and binding. The Exchange Agent and Pacific Premier reserve the right to waive any irregularities or defects in the surrender of any Certificate(s). A surrender will not be deemed to have been made until all irregularities have been cured or waived.

IMPORTANT TAX INFORMATION

Under current U.S. federal income tax law, a shareholder who tenders one or more Certificates that are accepted for exchange may be subject to backup withholding. In order to avoid such backup withholding, the shareholder must provide the Exchange Agent with such shareholder's correct TIN and certify that such shareholder is not subject to such backup withholding by completing the Substitute Form W-9 provided herewith. In general, if a shareholder is an individual, the TIN is the SSN of such individual. If the Exchange Agent is not provided with the correct TIN, the shareholder may be subject to a $50 penalty imposed by the IRS. For further information concerning backup withholding and instructions for completing the Substitute Form W-9 (including how to obtain a TIN if you do not have one and how to complete the Substitute Form W-9 if the Certificate(s) is (are) held in more than one name), consult the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9.

Certain shareholders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. In order to satisfy the Exchange Agent that a foreign individual qualifies as an exempt recipient, such shareholder must submit a statement, signed under penalties of perjury, attesting to that individual's exempt status, on a properly completed Form W-8BEN, or successor form. Such statements can be obtained from the Exchange Agent.

Failure to complete the Substitute Form W-9 will not, by itself, cause the Certificate(s) to be deemed invalidly tendered, but may require the Exchange Agent to withhold a portion of the amount of any payments made pursuant to the Merger Agreement. Backup withholding is not an additional federal income tax. Rather, the federal income tax liability of a person subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained provided that the required information is furnished to the IRS.

NOTE: FAILURE TO COMPLETE AND RETURN THE SUBSTITUTE FORM W-9 MAY RESULT IN BACKUP WITHHOLDING OF A PORTION OF ANY PAYMENTS MADE TO YOU PURSUANT TO THE MERGER AGREEMENT. PLEASE REVIEW THE ENCLOSED GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION NUMBER ON SUBSTITUTE FORM W-9 FOR ADDITIONAL DETAILS.

Privacy Act Notice.—Section 6109 requires most recipients of dividend, interest, or certain other income to give TINs to payers who must report the payments to the IRS. The IRS uses the numbers for identification purposes and to help verify the accuracy of tax returns. The IRS may also provide this information to the U.S. Department of Justice for civil and criminal litigation and to cities, states and the District of Columbia to carry out their tax laws. The IRS may also disclose this information to other countries under a tax treaty, or to federal and state agencies to enforce federal nontax criminal laws and to combat terrorism. Payers must be given the numbers whether or not recipients are required to file tax returns. Payers must generally withhold a portion of taxable interest, dividend, and certain other payments to a payee who does not furnish a TIN to a payer. Certain penalties may also apply.

Penalties

(1) Penalty for Failure to Furnish TIN.—If you fail to furnish your TIN to a payer, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

(2) Civil Penalty for False Information With Respect to Withholding.—If you make a false statement with no reasonable basis which results in no imposition of backup withholding, you are subject to a penalty of $500.

(3) Criminal Penalty for Falsifying Information.—Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.

(4) Misuse of TINs.—If the requester discloses or uses TINs in violation of federal law, the requester may be subject to civil and criminal penalties.
