Fifth Third Bancorp today announced it has completed the technical conversion of approximately 600,000 customers’ accounts and 293 banking centers across Michigan, Arizona, California, Florida, and Texas from the Comerica franchise.
Executed over Labor Day weekend, the conversion brings Comerica consumer and commercial customers onto Fifth Third’s platforms.
According to the Cincinnati-based Fifth Third, the announcement completes the integration that began when it merged with Comerica on Feb. 1, 2026. The combined company now is the ninth-largest U.S. bank with more than $300 billion in assets, operations in 17 of the 20 fastest-growing large U.S. metropolitan areas, and a retail footprint that reaches more than half of the U.S. population.
With the companies now operating on a single platform and under a single brand, Comerica customers gain access to Fifth Third’s full suite of consumer, commercial, payments, and wealth capabilities, including the Momentum Banking suite and mobile app with features such as Early Pay and Extra Time.
The offerings are backed by a network of approximately 1,500 branches and 21,300 ATMs. For customers, the change means new products and broader services delivered by the same local bankers and relationship teams they know, according to Fifth Third.
“The power of this merger comes from what we can accomplish together as one team,” says Tim Spence, chairman, president, and CEO of Fifth Third. “Now that we’re on one platform, we can bring the full strength of the combined company to every client, in every market we serve.
“Our teams planned, trained, and tested for this moment, and they delivered a disciplined conversion this weekend. We’re continuing to monitor the customer experience closely and are ready to help wherever needed.”
With the conversion complete, Fifth Third is positioned to build on its market presence in the Midwest while continuing to invest in markets across Texas, the Southeast, Arizona, and California.
In Michigan, Fifth Third holds the No. 1 retail deposit share statewide and in Detroit. Following the conversion, Comerica customers will gain 60 percent more branch access, while existing Fifth Third customers gain 42 percent more access.
In Texas, Fifth Third now operates 107 financial centers and plans to invest nearly $1 billion over the next five years, including opening 150 new financial centers by 2029 to strengthen its position in one of the nation’s fastest-growing economic markets.
Across former Comerica markets, Fifth Third expects household growth to accelerate as the full suite of products, digital capabilities, and analytically driven direct marketing are introduced to new markets.
By 2030, Fifth Third says it expects to operate approximately 1,750 branches, with more than half of the network located in markets across Texas, the Southeast, Arizona, and California.
