FB Financial Corporation is a financial holding company that operates FirstBank and its subsidiaries, providing comprehensive commercial and consumer banking services across Tennessee, Alabama, Kentucky, Georgia, and North Carolina through a network of full-service branches and mortgage offices. The company generates revenue through two main segments: its banking business, which earns interest on loans and investments, fee income from lending, trust and investment services, and deposits, funded primarily by customer deposits and supplemented by credit facilities and brokered deposits; and its mortgage banking segment, which generates revenue from loan origination fees, sales of mortgages in the secondary market, and mortgage servicing. As a regional bank holding company, FB Financial's performance is influenced by interest rate movements, credit quality trends in its operating markets, and broader economic conditions.
