Industry Context

This merger represents a significant consolidation within the Western U.S. regional banking sector, aiming to create a larger entity with enhanced market leadership and broader geographic reach. It aligns with a broader industry trend where regional banks seek scale to compete more effectively, optimize operations, and offer a wider range of services. The combined entity will be one of the largest banks headquartered in the West, serving a diverse customer base across multiple states.

Comparison to Industry Standards

• Columbia Bank, with over $50 billion in assets, is positioned as the largest bank headquartered in the Northwest and one of the largest in the West.
• Pacific Premier Bank, with approximately $18 billion in total assets, is noted as one of the largest banks headquartered in the western region of the United States.
• The combined entity will have assets exceeding $68 billion, placing it among the larger regional banks in the U.S., comparable in scale to other significant regional players like Zions Bancorporation (ZION) or Western Alliance Bancorporation (WAL) in terms of asset size and regional focus.
• The overwhelming shareholder approval (over 99% of votes cast for the proposal) indicates strong investor confidence in the strategic rationale of the merger, which is a positive sign compared to mergers that might face significant shareholder dissent.

Stakeholder Impact

• Shareholders: Expected to benefit from enhanced market leadership and significant value creation from the combined entity, though Columbia shareholders will experience dilution due to the issuance of new shares.
• Customers: Expected to benefit from the full breadth of combined resources and capabilities, and potentially a wider range of services from a larger regional bank.
• Communities: Expected to benefit from the enhanced market leadership and value creation.
• Employees: Potential for changes in business or employee relationships due to the merger and integration process.

Next Steps

• Obtain remaining necessary regulatory approvals for the transaction.
• Satisfy other remaining customary closing conditions set forth in the merger agreement.
• Complete the transaction, which is anticipated later in 2025.
• Integrate the operations of Columbia and Pacific Premier following the closing.

Key Dates

Recommendation

The overwhelming shareholder approval significantly de-risks the completion of this major strategic merger for Columbia Banking System. The combined entity will create a larger, more competitive regional bank in the Western U.S. with over $68 billion in assets, enhancing market leadership and creating value through synergies. While general banking industry risks persist, the successful shareholder vote removes a key execution hurdle, making the stock more attractive for long-term growth potential stemming from the combined entity's increased scale and capabilities.
