Fifth Third Bancorp completed its acquisition of Comerica on February 1, 2026, creating the ninth-largest US bank with roughly 294 billion dollars in assets, per the company's announcement. The all-stock deal, valued at 10.9 billion dollars when it was announced in October 2025, closed in under four months.

What Closed on February 1?
The merger of Fifth Third, headquartered in Cincinnati, and Dallas-based Comerica combined two regional banking franchises across the Midwest, Texas, and California. Per Fifth Third's January 13, 2026 statement, all material regulatory approvals had been received by that date, and Comerica shareholders had approved the deal days earlier with roughly 97 percent of votes cast in favor, per the companies' disclosures.
The speed was the story. A deal announced in October 2025 clearing the Federal Reserve and other regulators and closing on February 1, 2026 marks one of the fastest large-bank approvals of the post-2023 cycle, and a signal of how the merger environment has shifted since the regional bank stress of that year.
What Does the Combined Bank Look Like?
The combined institution holds roughly 294 billion dollars in assets, ranking ninth among US banks, per the company's February 2026 announcement. Fifth Third keeps its Cincinnati headquarters and brand, while Comerica branches and accounts migrate onto Fifth Third systems over the following months.
Customer conversion is scheduled for September 8, 2026, per Fifth Third's integration timeline — the point at which Comerica accounts, cards, and direct deposits rebrand. Until then, both banks operate on separate platforms, the standard dual-run period that integration teams use to move core systems without breaking payment rails.
Why Did Regional Bank Mergers Come Back?
Comerica-Fifth Third was the largest deal of a broader wave. Through 2025, mid-sized banks pursued combinations to spread technology and compliance costs across bigger footprints, and regulators signaled a more receptive posture toward well-structured regional mergers than during the years immediately after the 2023 failures of Silicon Valley Bank, Signature, and First Republic.
The economics push in the same direction. Branch counts fell by roughly 1,000 over the latest annual FDIC reporting period, per an American Bankers Association analysis of the FDIC's 2024 Summary of Deposits — consolidation pressure that shows up as deals as well as closures. Scale spreads fixed costs across more deposits, and the combined bank's pro forma size pushes it further into the regulatory perimeter that applies to firms above 100 billion dollars in assets.
What Happens Next?
Integration, then the September 8, 2026 conversion. Fifth Third's stated focus through the dual-run period is keeping payment continuity: direct deposits, ACH origination, and card processing continue on existing rails while systems merge behind them, per the company's integration communications.
For payments and treasury counterparties, the operational calendar matters more than the closing press release: routing and account data change at conversion, not at legal close. Teams that track counterparty risk have the date circled, and the FDIC insurance line — 250,000 dollars per depositor, per bank — now applies once, across the merged institution, rather than separately at two banks.
