AI brief of an SEC Form 8-K · Columbia Banking System (COLB)

Columbia Banking agrees to merge with Pacific Premier Bancorp in stock deal

Neutral Impact 5 of 5 m&a Written later

Columbia Banking System signed a merger agreement on April 23, 2025, to acquire Pacific Premier Bancorp, with Pacific Premier shareholders receiving 0.9150 of a Columbia share for each share they hold. The deal requires shareholder and regulatory approvals before completion, and a $75 million termination fee applies in certain circumstances, so the deal's outcome remains uncertain.

Key points

  • Exchange ratio: 0.9150 Columbia common share per Pacific Premier share, with cash paid for fractional shares
  • Three Pacific Premier directors, including Chairman, CEO and President Steven R. Gardner, expected to join Columbia's board
  • Completion requires shareholder approvals, Federal Reserve, FDIC and Oregon approvals, and an S-4 registration statement
  • Termination fee of $75,000,000 payable by either party in certain circumstances
