First Interstate Bank login: The first interstate bank was established in 1968 when its founder, Homer Scott, Sr., purchased the Bank of Commerce in Sheridan, Wyoming. First Interstate Bank is a community banking organization headquartered in Billings, Montana. With more than 150 locations in Idaho, Montana, Oregon, South Dakota, Washington, and Wyoming, First Interstate still operates on the same principles, founded in 1968 by Homer Scott, Sr., in Sheridan, Wyoming. Potentially to take care of our customers, our employees, and the places we call home.
Scott incorporated the company in Montana in 1971 and over the next 10 years acquired two more banks and established six de novo banks in Montana and Wyoming. In 1996, Wells Fargo acquired First Interstate Bancorp, but not First Interstate Bank. Instead, the Montana organization successfully negotiated to retain the famous First Interstate name and logo. In 2017, the company retained the right to use the First Interstate name and logo in all 50 states.
The bank acquired Cascade Bancorp in 2017 and Northwest Bancorp, Inc. in 2018. It expanded into Idaho, Oregon, and Washington—parent companies of Bank of the Cascades and Inland Northwest Bank, respectively. In 2019, Idaho Independent and Community First Bank joined the company, officially becoming the First Interstate Bank in June of that year. As of 2021, First Interstate has 150 branches in Idaho, Oregon, Montana, South Dakota, Washington, and Wyoming.
In September 2021, First Interstate announced a merger with South Dakota-based Great Western Bank, Sioux Falls. The merger was completed on February 1, 2022, making Great Western an operating division of First Interstate Bank; Great Western locations will become the first interstate bank branches on May 23, 2022.
