Third Coast Bank, SSB.

What Third Coast Bank, SSB. does

Third Coast Bank, SSB is a Texas-chartered, FDIC-insured community bank headquartered in Humble, Texas, operating 21 branches and 2 loan production offices across the state's four largest metropolitan areas — Greater Houston, Dallas-Fort Worth, Austin, and San Antonio. Founded in 2008 with $17 million in assets, the bank grew to over $6 billion in assets by 2026, going public on NASDAQ in November 2021 and subsequently transferring its listing to NYSE and NYSE Texas under ticker TCBX. The bank serves five primary customer segments: middle-market corporate banking, small business banking, consumer mortgage lending (licensed in all 50 states), consumer retail banking, and Premier/high-net-worth banking through Third Coast Advisors.

The product suite spans personal and business deposit products (checking, savings, money market, CDs, IRAs), a full residential mortgage platform (conventional, FHA, VA, USDA, jumbo, construction, non-QM, DSCR, and a Professional Program offering 100% financing for doctors, attorneys, and CPAs), commercial and SBA lending (7(a) and 504), and treasury management services including ACH origination, Positive Pay, online wires, Remote Deposit Capture, sweep, lockbox, and merchant card services. Technology is delivered through the TCB Banking mobile app (iOS/Android with Zelle, mobile deposits), online banking for retail and business, Intuit OFX connectivity for QuickBooks and Quicken, and a multi-layer security architecture.

The business model combines net interest income from a loan portfolio (commercial real estate, construction, residential mortgage, consumer) with non-interest income from treasury management fees, mortgage banking, deposit service charges, and a growing securitization fee stream — including a $150 million CRE securitization with EJF Capital that earned Structured Credit Investor's 2025 North American Transaction of the Year award. The bank completed its merger with Keystone Bancshares, Inc. on February 1, 2026 in a transaction valued at approximately $123 million, adding roughly $812 million in loans, $1 billion in assets, and $844 million in deposits, and creating one of the largest independent Texas-based banking franchises.
