Who Owns Fifth Third Bank?

The bank traces to the Bank of the Ohio Valley, chartered in Cincinnati in 1858, when the city was a major riverport and commercial center west of the Appalachians. Successor institutions merged repeatedly through the 19th century.

The famous name arrived in 1909. The Fifth National Bank and the Third National Bank of Cincinnati combined that year, and the merged institution took the straightforward name Fifth-Third National Bank of Cincinnati. The hyphenated numbering, later streamlined to Fifth Third Bank, has outlasted every attempt to rename it.

The odd fraction became a marketing asset. The bank leans into the name with 5/3 branding, celebrates May 3 as an informal bank holiday among employees and customers, and attaches the Fifth Third name to venues across its footprint, including Fifth Third Field ballparks in Toledo and Dayton and the Fifth Third Arena at the University of Cincinnati.

Through the 20th century the bank grew with Cincinnati's manufacturing and consumer goods economy, financing the region's factories and retailers. It formed the Fifth Third Bancorp holding company in the 1970s and began acquiring community banks across Ohio, Kentucky, and Indiana.

The 1990s and 2000s took the brand south and north at once, into Florida, Michigan, Illinois, Tennessee, and the Carolinas through deals and branch building. Along the way the bank absorbed dozens of local nameplates, from Old Kent Bank in Michigan to First Charter in the Carolinas, and converted them all to Fifth Third.

The 2008 crisis forced a $3.4 billion TARP infusion, repaid in 2011, and a retrenchment that refocused the bank on Midwest and Southeast markets. The 2018 acquisition of MB Financial then made Fifth Third a major player in Chicago, its largest single metro market outside Cincinnati.

The largest step in brand history came in October 2025, when Fifth Third announced an all-stock acquisition of Comerica of Dallas valued at about $10.9 billion. The deal closed February 1, 2026, and the September 2026 systems conversion put the Fifth Third name on branches in Texas, California, Arizona, and Florida, markets where the brand had been thin or absent.

For Comerica customers, the change was deliberately seamless in staffing and jarring in signage. Relationship teams stayed in place, but the Comerica name, older than Fifth Third itself, disappeared from roughly 300 banking centers within days of the conversion.
