Comerica is a Dallas-based commercial bank focused primarily on business banking. Its core business is commercial lending — extending credit to middle-market companies, large corporations, and specialized industries — paired with treasury management and deposit services. Comerica operates through three segments: Commercial Bank (the core franchise), Retail Bank (consumer and small business banking), and Wealth Management (trust, private banking, and investment services, partially delivered through a partnership with Ameriprise Financial). Comerica runs several national specialty businesses alongside its core markets, including National Dealer Services, Environmental Services, Technology and Life Sciences, and Equity Fund Services. Comerica makes money primarily through net interest income — the spread between loan and securities yields and deposit funding costs — with secondary revenue from treasury management fees, card fees, capital markets, and wealth services. A key competitive advantage is Comerica's high proportion of noninterest-bearing deposits, which management describes as peer-leading and which are largely tied to treasury management relationships with business customers. Comerica operates primarily across five markets — Texas, California, Michigan, Arizona, and Florida — and is selectively expanding in the Southeast and Mountain West through relationship manager hires. Growth strategy centers on organic expansion through banker hiring and development, growing fee income, and deepening treasury management relationships. One near-term risk is the loss of the Direct Express federal prepaid card contract, which has historically contributed roughly $3.3B in noninterest-bearing deposits that Comerica will need to replace organically.
