Ticker: COLBFinancialsBanks & BrokersThe business
Columbia Banking System, Inc. (NASDAQ: COLB) operates as a registered financial holding company providing comprehensive banking and financial services through its principal subsidiary, Columbia Bank. The company's website is www.columbiabank.com.
Columbia Bank serves corporate, institutional, small business, and individual customers across Arizona, California, Colorado, Idaho, Nevada, Oregon, Texas, Utah, and Washington. The bank significantly expanded its footprint in August 2025 through the acquisition of Pacific Premier Bancorp, which accelerated the company's Southern California expansion strategy and enhanced its presence in other growth markets. Following this acquisition, the bank unified its brand identity under the "Columbia Bank" name effective September 1, 2025.
The company's core business encompasses commercial lending products including lines of credit, term loans, equipment financing, real estate construction loans, and SBA program financing. Columbia offers treasury management and payments solutions featuring business digital banking, ACH services, wire transfers, remote deposit capture, and international banking products. Deposit products include non-interest-bearing checking accounts, interest-bearing savings and money market accounts, and certificates of deposit. The company operates a substantial wealth management division providing financial planning, investment management, trust services, insurance solutions, and private banking through Columbia Wealth Advisors, Columbia Trust Company, Columbia Private Trust, and Columbia Private Bank. Residential real estate lending and consumer loan products round out the service offerings, with FinPac, a commercial equipment leasing subsidiary, contributing to the business mix.
As of December 31, 2025, Columbia employed 6,005 individuals, predominantly full-time associates. The workforce increased significantly due to the Pacific Premier acquisition. The company maintains 262 branches across its service territory, positioning it as a substantial regional banking franchise. Columbia Bank holds the number two deposit market share position in Oregon at 16.39 percent and maintains meaningful market presence in Washington, Idaho, and California. The company emphasizes relationship-driven banking, combining the financial sophistication of a regional institution with community bank service levels through its "Community Banking at Scale" strategy.
