## Geographic presence

As of the second quarter of 2026, Columbia Banking System identifies its primary markets and Columbia Bank offices in Arizona, California, Colorado, Idaho, Nevada, Oregon, Texas, Utah, and Washington. Its credit-risk disclosure says borrowers are primarily located in the other eight states, excluding Texas. [18](https://app.finbar.com/go?id=P146054088)[17](https://app.finbar.com/go?id=P146053992) The company’s public location directory lists branches in Arizona (4), California (96), Colorado (3), Idaho (24), Nevada (6), Oregon (105), Utah (2), and Washington (109); it does not list Texas. [19](https://locations.columbiabank.com/index.html)

The company also reports regional concentrations in its commercial real estate loan portfolio, including Southern California, the Bay Area and other Northern California, Puget Sound and other Washington, and Portland Metro and other Oregon. [20](https://app.finbar.com/go?id=P146054290)[21](https://app.finbar.com/go?id=T16716676) The available information provides geographic loan detail, but does not establish revenue or employee distribution by state or region.

## Business segments

As of the 2026 reporting year, Columbia Banking System reports one operating and reportable segment: its consolidated banking operations and related bank and holding-company activities, including technology and administration. The company does not report revenue or net interest income separately by business line; its single reportable segment therefore represents 100% of consolidated operations, rather than a separately disclosed percentage allocation among businesses. [18](https://app.finbar.com/go?id=P146054088)[22](https://app.finbar.com/go?id=P146054091)[23](https://app.finbar.com/go?id=P146054092)

Within that segment, the company’s activities include consumer and residential real-estate lending, commercial lending, deposits, treasury services and wealth management. Its banking businesses also include SBA lending, institutional and corporate banking, and equipment leasing; Columbia Wealth Management provides investment and wealth-management services, including healthcare and private banking. These are business lines, not separately reported segments. [18](https://app.finbar.com/go?id=P146054088)[1](https://app.finbar.com/go?id=P146054141) The company also groups loans into commercial real estate, commercial, residential, and consumer and other categories for credit-risk reporting; these are portfolio classifications, not operating segments.

## Company history

Columbia’s origins trace to First Federal Corporation, organized in 1988. Following a 1990 change in control, Columbia National Bankshares merged into the company in 1993, and Columbia National Bank merged into a newly chartered Columbia Bank; the bank identifies 1993 as its establishment year in Tacoma, Washington. [25](https://www.sec.gov/Archives/edgar/data/887343/000088734308000018/bex991.htm)[26](https://www.columbiabank.com/newsroom/umpqua-bank-and-parent-company-columbia-banking-system-celebrate-anniversaries-with-%241m-in-grants-for-local-nonprofits/) Columbia expanded into Oregon by acquiring Bank of Astoria in 2004, and in 2010 took over deposits and assets of Columbia River Bank and American Marine Bank. [27](https://www.columbiabankingsystem.com/news-market-data/press-releases/press-release/2004/Columbia-Banking-System-Inc.-Completes-Acquisition-of-Bank-of-Astoria/default.aspx)[28](https://www.columbiabankingsystem.com/news-market-data/press-releases/press-release/2010/Columbia-Banking-System-Acquires-Deposits-and-Assets-of-Columbia-River-Bank-The-Dalles-Oregon/default.aspx)[29](https://www.columbiabankingsystem.com/news-market-data/press-releases/press-release/2010/Columbia-State-Bank-Acquires-Substantially-All-of-the-Deposits-and-Assets-of-American-Marine-Bank-Bainbridge-Island-Washington/default.aspx)

The 2013 acquisition of West Coast Bancorp expanded Columbia’s presence across Washington and Oregon; its 2014 merger with Intermountain Community Bancorp brought the company into Idaho. [30](https://www.columbiabankingsystem.com/news-market-data/press-releases/press-release/2013/Columbia-Banking-System-Announces-Closing-Of-Acquisition-Of-West-Coast-Bancorp-Final-Merger-Consideration-Election-Results-And-Appointment-Of-Director/default.aspx)[31](https://www.prnewswire.com/news-releases/columbia-banking-system-enters-idaho-with-the-intermountain-community-bancorp-merger-268367942.html) Columbia completed its acquisition of Pacific Continental Corporation in 2017, then completed its merger with Umpqua Holdings Corporation on March 1, 2023. [32](https://www.columbiabankingsystem.com/news-market-data/press-releases/press-release/2017/Columbia-Banking-System-And-Pacific-Continental-Corporation-Enter-Into-Definitive-Agreement-To-Merge/default.aspx)[33](https://www.columbiabankingsystem.com/news-market-data/press-releases/press-release/2023/Columbia-Banking-System-and-Umpqua-Holdings-Corporation-Complete-Merger/default.aspx) In 2025, Columbia acquired Pacific Premier Bancorp and unified the bank under the Columbia name; the company reported that systems conversion was completed in the first quarter of 2026.
