The unaudited consolidated financial statements include the accounts of River Financial Corporation (“River” or the “Company”) and its wholly owned subsidiary, River Bank & Trust (“Bank”). The Bank provides a full range of commercial and consumer banking services primarily in the Montgomery, Alabama metropolitan area, Autauga, Baldwin, Chilton, Coffee, Elmore, Etowah, Houston, Lee, Mobile, Morgan and Tallapoosa counties and surrounding counties in Alabama.
