FB Financial is a Nashville-based bank holding company that operates community and commercial banking through its subsidiary, FirstBank. FirstBank operates across a five-state Southeast footprint — primarily Tennessee, Alabama, Georgia, Kentucky, and North Carolina — serving individuals, small and medium-sized businesses, and larger corporate clients through 90 full-service branches. The core banking model is straightforward: gather deposits and make loans across commercial real estate, C&I, residential mortgage, consumer, and construction segments. Beyond core banking, FB Financial runs a mortgage banking division focused almost entirely on purchase mortgages through a retail delivery model embedded in local markets. FB Financial earns primarily through net interest income, the spread between loan and investment yields and deposit costs, with a net interest margin near 4%. Roughly 45% of the loan book is floating-rate, making the bank modestly asset-sensitive. FB Financial pursues growth through two channels: organic expansion by recruiting local bankers with meaningful lending authority, and acquisitions — the company has completed 14 deals over 30 years and targets future acquisitions in the $3B–$7B asset range in the Southeast and Carolinas. The most recent deal was the July 2025 acquisition of Southern States Bancshares, adding roughly $2.8B in assets and expanding into Georgia. FB Financial argues it occupies a differentiated position — large enough to offer a full regional bank product suite, but locally managed enough to compete on responsiveness against larger institutions.
