Letter to our stakeholders

At Umpqua Bank, we're on a mission to ensure the long-term success of our stakeholders. We center our business decisions in our Do Right Together culture using a sustainable and disciplined approach. We consider how our impact will ripple outward to our

associates, customers, communities and shareholders.

Clint Stein

Chief Executive Officer

As one of the largest banks headquartered on the West Coast, our company has tremendous opportunity for making a positive impact in the communities we serve. This impact starts with our incredible people whose passion and commitment are evident in everything we do. In 2024, our associates volunteered almost 30,000 hours to over 1,200 community organizations while

our company gave $7.7 million to over 1,900 nonprofit organizations through sponsorships and the Umpqua Bank Charitable Foundation.

By providing financial expertise and capital, our associates help customers across our eight-state footprint navigate opportunities and challenges, building enduring relationships. In 2024, we made progress on our goal of increasing access to capital through our mortgage and small business

lending programs.

March 1, 2025, marked the two-year anniversary of the merger between Columbia Banking System and Umpqua Holdings Corporation. We are excited to deepen our impact by welcoming a new group of associates as we complete our acquisition of Pacific Premier Bancorp, expected later in 2025.

We strive to be a bank that serves our full community, and we are dedicated to helping our stakeholders prosper.
