Trustmark is a regional bank headquartered in Jackson, Mississippi, operating across the U.S. Southeast and select growth markets through its principal subsidiary, Trustmark Bank, which had roughly $19B in total assets at year-end 2025. Trustmark's core business is commercial and consumer banking — lending to businesses and consumers, and gathering deposits to fund that lending. Commercial real estate is the largest loan category at roughly $5.3B, alongside C&I, equipment finance, residential mortgage, and consumer loans. Trustmark operates through two segments: General Banking, which drives the overwhelming majority of revenue, and Wealth Management, a smaller fee-based business offering trust administration, investment management, brokerage, and retirement plan services. Trustmark earns money primarily through net interest income — the spread between loan and securities yields and deposit costs. Deposit cost discipline is a key differentiator; Trustmark's core personal and commercial deposit base is cheaper and stickier than brokered or wholesale funding. Noninterest income, roughly 20% of revenue, comes from mortgage banking, wealth management fees, service charges, and treasury management. Trustmark's growth strategy centers on organic expansion through hiring production talent and deepening its presence in high-growth markets, particularly Houston, Atlanta, Birmingham, and Huntsville. Trustmark is also opportunistic on M&A in the $1B–$10B asset range within contiguous markets, though management prioritizes organic execution.
