First Interstate Bancsystem, Inc.
A community bank holding company based in Billings, Montana, First Interstate Bank serves individuals, businesses, and municipalities across the western and midwestern United States with checking accounts, loans, mortgages, and wealth management. It began in 1968 when Homer Scott Sr. bought a small bank in Sheridan, Wyoming. Its name came from a separate Los Angeles banking giant; the Montana company licensed the First Interstate name in 1984 and later bought it outright from Wells Fargo in 2017, keeping a California-born brand for its prairie roots.
