Company Description
Pacific Premier Bancorp, Inc. (historically traded on Nasdaq under the symbol PPBI) was the parent company of Pacific Premier Bank, National Association, a nationally chartered commercial bank. According to company disclosures, Pacific Premier Bank focused on serving small, middle-market, and corporate businesses throughout the western United States in major metropolitan markets in California, Washington, Oregon, Arizona, and Nevada. The bank traces its roots to 1983 and grew over time to become one of the larger banks headquartered in the western region of the United States.
Public filings and joint press releases describe Pacific Premier Bank as providing banking products and services to businesses, professionals, entrepreneurs, real estate investors, and nonprofit organizations. These products and services included deposit accounts, digital banking, and treasury management services. On the lending side, Pacific Premier Bank offered a range of loan products such as commercial business loans, lines of credit, Small Business Administration (SBA) loans, commercial real estate loans, agribusiness loans, franchise lending, home equity lines of credit, and construction loans. The bank also operated specialized businesses, including commercial escrow services and facilitation of 1031 Exchange transactions through its Commerce Escrow division.
In addition to traditional commercial banking, Pacific Premier Bank provided IRA custodial services through its Pacific Premier Trust division. Company information notes that Pacific Premier Trust held assets under custody for self-directed investors, financial institutions, capital syndicators, and financial advisors. The bank also developed a nationwide presence in customized banking solutions for homeowners' associations (HOAs) and property management companies. These activities positioned Pacific Premier in several specialized banking verticals, including HOA banking, custodial trust operations, and commercial escrow services.
Prior to its acquisition, Pacific Premier Bancorp, Inc. was headquartered in Irvine, California, and operated within the commercial banking segment of the finance and insurance sector. The company reported through periodic financial results that highlighted metrics such as net interest income, net interest margin, cost of deposits, noninterest income, and capital ratios. These disclosures emphasized a relationship-based business model focused on small and middle-market business clients and on maintaining capital and asset quality levels consistent with regulatory expectations for a regulated commercial bank.
Acquisition by Columbia Banking System, Inc.
On April 23, 2025, Columbia Banking System, Inc. ("Columbia"), the parent company of Columbia Bank, and Pacific Premier Bancorp, Inc. jointly announced that they had entered into a definitive merger agreement under which Columbia would acquire Pacific Premier in an all-stock transaction. Subsequent joint communications explained that the combination was intended to create a larger western U.S. banking franchise with an expanded presence in key markets, including Southern California and other western states where both organizations operated.
On July 21, 2025, Pacific Premier reported that its stockholders approved the merger agreement at a special meeting, and Columbia shareholders approved the issuance of Columbia common stock as merger consideration. On August 6, 2025, the companies announced that all required regulatory approvals for the transaction had been obtained, including approvals from the Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation, and the Oregon Department of Consumer and Business Services, Division of Financial Regulation.
According to a Form 8-K filed on September 2, 2025, the merger closed effective August 31, 2025. In the first step, Balboa Merger Sub, Inc., a wholly owned subsidiary of Columbia, merged with and into Pacific Premier, with Pacific Premier surviving as the "Surviving Corporation." Immediately following that step, the Surviving Corporation merged with and into Columbia, with Columbia surviving the second-step merger. Promptly thereafter, Pacific Premier Bank, National Association, merged with and into Columbia Bank, with Columbia Bank surviving as the combined banking institution.
Under the terms of the merger agreement, each share of Pacific Premier common stock outstanding immediately prior to the effective time of the merger (other than certain excluded shares) was converted into the right to receive 0.9150 of a share of Columbia common stock, with cash paid in lieu of fractional shares. The Form 8-K notes that, as a result of the merger, the outstanding shares of Pacific Premier common stock were converted into the right to receive approximately 88,869,848 shares of Columbia common stock. Following completion of the transaction, former Pacific Premier stockholders collectively represented approximately 30% of Columbia's shareholders, as described in the joint press release announcing the closing.
Delisting and Reporting Status of PPBI
In connection with the completion of the merger, Pacific Premier Bancorp, Inc. took steps to remove its common stock from listing on Nasdaq and to terminate its registration under the Securities Exchange Act of 1934. A Form 8-K dated August 31, 2025 explains that Pacific Premier notified The Nasdaq Stock Market LLC on the closing date and requested suspension of trading of Pacific Premier common stock prior to the opening of trading on September 2, 2025, withdrawal of the listing, and filing of a Form 25 with the Securities and Exchange Commission (SEC) to effect the delisting.
On September 2, 2025, Nasdaq filed a Form 25 (Notification of Removal from Listing and/or Registration) for Pacific Premier Bancorp, Inc. common stock. The Form 25 identifies the issuer as PACIFIC PREMIER BANCORP INC, the exchange as Nasdaq Stock Market LLC, and the class of securities as common stock. The filing indicates that Nasdaq complied with its rules to strike the class of securities from listing and/or withdraw registration on the exchange. The Form 8-K further notes that Columbia, as successor to Pacific Premier, intends to file a Form 15 to terminate the registration of Pacific Premier common stock under Section 12(g) of the Exchange Act and to suspend Pacific Premier's reporting obligations under Sections 13 and 15(d) of the Exchange Act.
As a result of these actions, PPBI is no longer listed on Nasdaq, and Pacific Premier Bancorp, Inc. functions as a historical entity within Columbia's corporate structure rather than as an independent publicly traded company. For investors researching the PPBI ticker, the symbol now represents the historical record of Pacific Premier Bancorp, Inc. prior to its acquisition and integration into Columbia Banking System, Inc. and Columbia Bank.
Historical Business Profile
Before the merger, Pacific Premier Bancorp, Inc. reported that Pacific Premier Bank operated in major metropolitan markets across several western states and focused on commercial clients.

On the credit side, the bank's loan portfolio encompassed commercial business loans, lines of credit, SBA loans, commercial real estate loans, agribusiness loans, franchise lending, home equity lines of credit, and construction loans. Through Commerce Escrow, the bank provided commercial escrow services and facilitated 1031 Exchange transactions. Through Pacific Premier Trust, the organization offered IRA custodial services to a base of self-directed investors and institutional and advisory clients.

PPBI as a Former Public Company
Pacific Premier Bancorp, Inc. operated for many years as a publicly traded commercial banking company under the PPBI ticker. Its periodic reports, earnings releases, and investor presentations discussed net income, net interest margin, asset quality, capital ratios, and other measures typical for a regulated bank holding company. Following the completion of the merger with Columbia and the subsequent delisting and planned deregistration, PPBI's role for market participants is primarily historical. Current information about the combined banking organization, including financial performance and strategic direction, is now provided through Columbia Banking System, Inc. and Columbia Bank.
