of Pacific Premier Bank; </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>WHEREAS</B>, in connection with the closing of the Transaction, Consultant ceased being employed in all
capacities by PPBI and Pacific Premier Bank, which resulted in Consultant becoming entitled to receive the payments and benefits set forth in Section&nbsp;5(c) of Consultant&#8217;s Employment Agreement with PPBI and Pacific Premier Bank, dated as
of August&nbsp;30, 2021 (the &#8220;<B><I>Employment Agreement</I></B>&#8221;), subject to the terms and conditions set forth therein; and </P>

that such services may be provided remotely whenever possible: (i)&nbsp;integration of the business and operation of PBBI and Pacific Premier Bank into the Company&#8217;s and its subsidiaries&#8217; business and operations with respect to the
Transaction, (ii)&nbsp;client relations services, (iii)&nbsp;investor relations services and (iv)&nbsp;such other strategic matters as may be reasonably determined by the Company&#8217;s Chief Executive Officer<B> </B>(collectively, the

Consultant&#8217;s Services under this Agreement shall commence, on the date hereof and conclude on the date that is one year and one day after the date hereof (the &#8220;<B><I>Term</I></B>&#8221;), subject to earlier termination as provided in

connection with the provision of the Services will be the Company&#8217;s Chief Executive Officer. The Company and Consultant agree that the amount of time that Consultant spends providing the Services shall be reasonably determined by the Company.
The parties expect that the average weekly time commitment of Consultant in providing the Services during the Term will exceed 20% of Consultant&#8217;s average weekly hours worked for PBBI and Pacific Premier Bank during the <FONT

workers&#8217; compensation benefits, short term and long term disability benefits, vacation benefits, sick pay benefits, or pension plans that may be offered by the Company or any of its subsidiaries to their respective employees. Notwithstanding
the foregoing, Consultant shall retain all vested rights under the employee benefit plans of PBBI and its subsidiaries in which he participated while employed by PBBI or any of its subsidiaries, and shall retain all rights to subsidized premiums

from, or report possible violations of law or regulation to any governmental entity or self-regulatory authority, or to file a charge with or participate in an investigation conducted by any governmental entity or self-regulatory authority, and

information from any governmental entity or self-regulatory authority that is not directed to the Company or any of its affiliates or of Consultant&#8217;s decision to file a charge or complaint with or participate in an investigation conducted by
any governmental entity or self-regulatory authority. Notwithstanding the foregoing, Consultant recognizes that, in connection with the provision of information to any governmental entity or self-regulatory authority, Consultant must inform such
governmental entity or self-regulatory authority that the information Consultant is providing is confidential. Despite the foregoing, Consultant is not permitted to reveal to any third party, including any governmental entity or self-regulatory
authority, information Consultant comes to learn during Consultant&#8217;s service to the Company that is protected from disclosure by any applicable privilege, including but not limited to the attorney-client privilege or attorney work product
doctrine. Each of the Company and its affiliates does not waive any applicable privileges or the right to continue to protect its privileged attorney-client information, attorney work product, and other privileged information. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>TACOMA, Wash.,</B> (September 2, 2025)&#8212;Columbia Banking System, Inc. (&#8220;Columbia&#8221;) (Nasdaq:&nbsp;COLB), the parent company of Columbia
Bank, and Pacific Premier Bancorp, Inc. (&#8220;Pacific Premier&#8221;) (Nasdaq: PPBI), the parent company of Pacific Premier Bank, National Association (&#8220;Pacific Premier Bank&#8221;), jointly announced today the closing of Columbia&#8217;s
previously announced acquisition of Pacific Premier. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The addition of Pacific Premier advances Columbia&#8217;s strategic expansion in Southern California
by more than a decade and further solidifies its market leadership in Northern California, Washington, Oregon and Arizona, strengthening its position as a leading western U.S.-based financial institution. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">&#8220;Today marks an exciting milestone for our company. Columbia&#8217;s acquisition of Pacific Premier significantly accelerates our expansion in key
western markets and unites two exceptional and complementary banks focused on delivering superior value to all our stakeholders,&#8221; said Clint Stein, Columbia President&nbsp;&amp; CEO. &#8220;We are thrilled to welcome Pacific Premier
associates, customers and communities to our company. We remain laser-focused on executing a seamless and efficient integration under the unified Columbia family of brands, in support of long-term shareholder value.&#8221; </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">At transaction close, Columbia&#8217;s assets increased to approximately $70&nbsp;billion with approximately $50&nbsp;billion in loans and $56&nbsp;billion in
deposits. The combined organization will operate more than 350 locations across eight western states&#8212;Washington, Oregon, California, Arizona, Colorado, Nevada, Utah and Idaho&#8212;reinforcing Columbia&#8217;s position as a regional banking
leader with deep local roots and broad geographic reach. The company expects to integrate its systems and services in the first quarter of 2026. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Columbia Bank Name Change Complete </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Effective
September&nbsp;1, 2025, Columbia Bank began serving customers under its unified name and brand, completing the transition announced earlier this year from the Umpqua Bank name. The change ensures brand clarity by simplifying Columbia&#8217;s family
of brands, which also includes Columbia Wealth Management, Columbia Trust Company, Columbia Private Bank&nbsp;and Columbia Wealth Advisors. </P>
