Insights

TL;DR: The amendment supplies required Pacific Premier financials and pro forma statements, a necessary step to complete M&A disclosure.

The filing addresses a material omission by adding the target's audited financial statements and pro forma adjustments, which are essential for investors to evaluate the financial impact of the pending mergers. Inclusion of Exhibit 99.1 and Exhibit 99.2 enables analysis of historical results and the estimated combined balance sheet and income statement effects. The amendment does not change other disclosed terms, indicating the disclosures were limited to supplemental financial information rather than revised deal economics.

TL;DR: Investors gain access to the target's financials and pro forma metrics; necessary for assessing post-transaction scale and accounting effects.

Providing the attached financial statements and pro forma information closes a disclosure gap that would otherwise hinder assessment of earnings accretion/dilution, capital ratios, and balance sheet composition after the mergers. The amendment’s scope is narrowly defined to add exhibits, so analysts should review Exhibits 99.1 and 99.2 directly for specific metrics and adjustments rather than relying on this cover amendment.

Explanatory Note

On September 2, 2025, Columbia Banking System, Inc., a Washington corporation (“Columbia”), filed a Current Report on Form 8-K (the “Original Report”) to report that, effective as of August 31, 2025, Columbia completed its acquisition of Pacific Premier Bancorp, Inc., a Delaware corporation (“Pacific Premier”), pursuant to the Agreement and Plan of Merger, dated April 23, 2025 (the “Merger Agreement”), by and among Columbia, Pacific Premier, and Balboa Merger Sub, Inc., a Delaware corporation and a direct, wholly owned subsidiary of Columbia (“Merger Sub”). Pursuant to the Merger Agreement, (i) Merger Sub merged with and into Pacific Premier (the “Merger”), with Pacific Premier as the surviving corporation, and (ii) immediately thereafter, Pacific Premier merged with and into Columbia, with Columbia as the surviving entity (the “Second Step Merger” and, together with the Merger, the “Mergers”).
