Comerica Incorporated (CMA)

Comerica Incorporated was a financial services company with headquarters in Dallas, Texas. Its roots go back to the Detroit Bank founded in 1849, and the company was long associated with Michigan. It moved its headquarters to Dallas in 2007 and built a national commercial banking franchise, with major operations in Texas, California and Michigan, as well as Arizona, Florida and Canada.

The company was best known for business banking. Its Commercial Bank served small and mid-sized companies, large corporations and governmental entities with lending, treasury management, international trade finance and capital markets products. A Retail Bank and Wealth Management group served individuals, small businesses and affluent clients, while a Finance segment managed the securities portfolio and balance sheet.

Comerica's common stock was listed on the New York Stock Exchange under the ticker CMA, and its depositary shares of preferred stock traded as CMA-PB. In the 2020s the bank worked through a period of rising interest rates and pressure on deposit costs, particularly as a bank with a large share of commercial and noninterest-bearing deposits. Its shares drew takeover interest from investors who pushed for strategic options.

On October 6, 2025, Comerica and Fifth Third Bancorp of Cincinnati announced a definitive agreement to combine in an all-stock transaction valued at about $10.9 billion. The structure was later described as a mixture of shares and cash. Under the terms each Comerica share was exchanged for 1.8663 shares of Fifth Third common stock plus $5.00 in cash.

The deal created one of the largest U.S. regional banks, adding Comerica's commercial franchise and its presence in Texas and California to Fifth Third's Midwest and Southeast footprint. Comerica and Fifth Third shareholders approved the transaction, and bank regulators granted clearances in early 2026.

The merger was completed on or about February 1, 2026. Comerica's stock last traded on the NYSE on January 30, 2026, and a Form 25 was filed on February 2, 2026 covering the common stock and the depositary shares of the Series B preferred. Fifth Third continues as the surviving company and trades on Nasdaq under FITB.
