Fifth Third Bancorp Closes 75 Michigan Branches After Comerica Acquisition

What happened

Fifth Third Bank announced the closure of 75 branches across Michigan following its $12.7 billion all-stock acquisition of Comerica Bank in February. The closures, expected to be completed by early September, include 55 legacy Comerica branches and 20 existing Fifth Third branches. The final list was filed with the Office of the Comptroller of the Currency and includes locations across metro Detroit, Grand Rapids, Ann Arbor, and other Michigan markets. Some notable closures include a Fifth Third branch at 3313 West 12 Mile Road in Farmington Hills, a Comerica branch on 14 Mile Road in Walled Lake, and a Comerica branch on North Main Street in Ann Arbor. Fifth Third plans to convert all Comerica customers to its system over the Labor Day weekend, ending the use of the Comerica Bank name, which dates back to 1982. The company has also filed a Worker Adjustment and Retraining Notification indicating plans to lay off 502 workers at Comerica's Great Lakes Campus in Farmington Hills between July and November.

Why it matters

The branch consolidation reflects the operational integration following one of the largest U.S. regional bank mergers in recent years. The combined entity creates the ninth-largest U.S. banking company, extending Fifth Third's presence in Michigan while eliminating overlapping locations. For customers, the merger means expanded branch access-Fifth Third customers will have 40% to 45% more branches available, while former Comerica customers gain access to 60% more branches than before. The company will operate 227 financial centers across 39 Michigan counties post-integration. Fifth Third emphasized that most closing branches have another location within one mile, and employees from closing branches are being prioritized for transfer to receiving locations to maintain customer service continuity. The closures also represent a strategic shift as banks consolidate physical footprints while maintaining competitive coverage in key markets.

Bigger picture

This consolidation reflects broader trends in U.S. banking as regional institutions pursue scale through mergers to compete more effectively. The Fifth Third-Comerica deal is part of ongoing consolidation among mid-sized banks seeking to expand market share, improve operational efficiency, and invest in digital capabilities while managing physical branch networks. The merger also marks a significant shift for Michigan's banking landscape, as Comerica-founded in Detroit in 1849-loses its brand identity after relocating its headquarters to Texas in 2007. Fifth Third's expansion makes it the largest banking network in several Michigan counties, including Kent, Ottawa, and Muskegon. The integration timeline, with system conversion over Labor Day weekend, represents a critical operational milestone that will determine customer retention and satisfaction as the combined entity establishes its market position.

What to watch

Key milestones include the Labor Day weekend conversion of Comerica customers to Fifth Third systems and the completion of all branch closures by early September. Investors should monitor customer retention rates and any service disruptions during the conversion period, as smooth execution is critical to realizing merger synergies. The workforce transition, including the relocation of employees from closing branches and the 502-person layoff at the Farmington Hills campus, will impact integration costs and employee morale. The naming rights for Detroit Tigers' Comerica Park, set to change after the 2026 baseball season, represent another brand transition to watch. Longer-term, Fifth Third's ability to leverage its expanded 227-branch Michigan network to grow deposits and lending volumes will determine whether the acquisition delivers anticipated financial benefits.
