Fifth Third’s (FITB) Comerica Merger Is Done, Now Comes The Payoff
Fifth Third Bancorp (FITB) completed its merger with Comerica, integrating 600,000 customers and 293 branches. The bank now ranks ninth in the U.S. by assets, with over $300 billion. Early results show deposit growth and improved margins, but merger costs and funding pressures remain. Hedge fund ownership declined, and the stock's P/E ratio is 10.82, reflecting mixed investor sentiment.
How this was made

What to watch
Potential regulatory scrutiny on capital adequacy and the pace of expense normalization.
Background

Limited to U.S. regional banks; no broader global impact.
