The investor conference call is slated for 2:00 p.m. PT, or 5:00 p.m. ET. Participants looking to engage in the live question-and-answer session must register in advance to receive unique dial-in credentials. For those preferring to observe the proceedings without direct participation, a listen-only audiocast will be available. The company advises attendees to connect at least 10 minutes before the scheduled start time to ensure a smooth transition into the presentation.

Following the event, a replay will be archived on the investor relations section of the Columbia Banking System website. Headquartered in Washington, the bank currently maintains a regional presence across nine states, including California, Oregon, and Arizona, offering services ranging from commercial banking to private wealth management. Investors are encouraged to review the company's recent SEC filings, including its 2025 Annual Report and 2026 quarterly statements, for detailed context on the financial risks and projections that may influence future performance.
