Southside Bancshares is a Texas-focused community bank holding company that operates through its subsidiary, Southside Bank, headquartered in Tyler, Texas. The bank serves individuals, businesses, municipalities, and nonprofits across East Texas, Southeast Texas, and the Dallas-Fort Worth, Austin, and Houston markets through 53 branches. Southside's core business is traditional community banking: taking in deposits and deploying capital into loans and securities. The loan book is predominantly commercial real estate, with a growing commercial & industrial component. Alongside its loan book, Southside holds a large securities portfolio weighted toward municipal bonds and agency mortgage-backed securities. The bank earns primarily through net interest income — the spread between what it earns on loans and securities and what it pays on deposits. Southside also offers wealth management and trust services, including investment management, trust administration, and estate services, with roughly $1.65B in assets under management. Noninterest income is a secondary contributor, driven by trust fees, brokerage income, and deposit service charges. Southside is actively expanding within Texas, building out its presence in Houston and Dallas-Fort Worth through loan production offices and new retail branches, while also hiring commercial bankers to grow C&I lending. The bank is also pursuing acquisitions, targeting culturally aligned banks under ~$1.5B in assets to fill geographic gaps in its key growth markets.
