Fifth Third Bancorp (NYSE: FITB) completed the technical conversion of Comerica’s customer accounts over the Labor Day weekend, finishing the operational integration of its acquisition of the Texas-based bank.
About 600,000 Comerica customer accounts and 293 banking centers were moved onto Fifth Third’s platform during the transition. Former Comerica consumer and commercial customers across Arizona, California, Florida, Michigan and Texas have been integrated into Fifth Third’s branch and digital systems.
The merger, which closed on February 1, 2026, has made Fifth Third the ninth-largest U.S. bank by assets, with more than $300 billion under management. The combined institution now operates roughly 1,500 branches and 21,300 ATMs across 17 of the 20 fastest-growing large U.S. metropolitan areas.
In Michigan, where Fifth Third already holds the top retail deposit share statewide and in the Detroit market, former Comerica customers now have about 60% more branch access, while existing Fifth Third customers have gained approximately 42% more access. In Texas, Fifth Third operates 107 financial centers and has said it plans to invest nearly $1 billion over the next five years, including opening 150 new branches by 2029.
By 2030, Fifth Third expects its total branch count to reach approximately 1,750, with more than half located in Texas, the Southeast, Arizona and California. Former Comerica customers also gained access to Fifth Third’s product offerings, including the Momentum Banking suite and mobile app features, while continuing to be served by their existing local bankers and relationship teams.
Tim Spence, chairman, CEO and president of Fifth Third, said the company is now operating on a single platform and can bring the combined firm’s full strength to clients across all markets served.
