Third Coast Bancshares, Inc. operates as a bank holding company for Third Coast Bank, SSB, a Texas state savings bank. The company's business model is centered on traditional community and commercial banking, generating revenue primarily from the net interest spread between its loan portfolio and customer deposits, supplemented by fee income from treasury management, card usage, and transaction services. Its loan portfolio is diversified across commercial and industrial (C&I) loans, commercial real estate, construction and development, and consumer loans. The bank gathers low-cost deposits through checking, savings, and money market accounts. Geographically, Third Coast focuses its footprint on major Texas markets, including Greater Houston, Dallas-Fort Worth, and Austin-San Antonio. In early 2026, the company expanded its scale and market presence by completing a merger with Keystone Bancshares, Inc., pushing its total assets past $6.5 billion. The company distinguishes itself by offering relationship-driven banking tailored to local businesses, professionals, and property owners, competing against both large national lenders and smaller community banks.
