Comerica stock gains as Fifth Third merger integration advances

Comerica Inc. stock (US2003401070) traded at a transaction value of USD 82.88 per share after Fifth Third's all-stock takeover closed, with that deal price cited on September 19, 2026. As Yahoo Finance reported on September 19, 2026, the integration moved into the payoff phase.
Deal value and synergy target
That headline figure came from the merger agreement signed in October 2025, when Fifth Third valued Comerica at about USD 10.9 billion and offered 1.8663 Fifth Third shares for each Comerica share. WebProNews said that the implied value was about USD 82.88 per Comerica share at announcement, a premium of roughly 20 percent.
For investors, the key number is not the premium anymore but the execution target. Fifth Third projects USD 850 million in pre-tax run-rate cost synergies by the fourth quarter of 2026, and it sees revenue opportunities above USD 500 million over the next three to five years, according to WebProNews on September 19, 2026.
Balance sheet reset
The same report said Fifth Third gathered USD 2.5 billion in consumer deposits from its Southwest marketing push tied to the Comerica franchise, while fee revenue in those markets jumped 35 percent year over year. It also said newline deposits rose USD 2.1 billion and the net interest margin widened 6 basis points sequentially to 3.36 percent.
Those figures matter because they show where the merger is expected to create scale: deposits, fees and margin, not just headline size. Fifth Third also said adjusted efficiency improved to 57.1 percent, down 480 basis points from the prior quarter, which gives the integration story a measurable operating benchmark.
What the stock now reflects
The market value of Comerica stock is now tied to the Fifth Third exchange ratio rather than an independent standalone quote, so the transaction value of USD 82.88 is the most relevant reference point as of September 19, 2026. The closing paragraph therefore centers on the merger economics, not a fresh trading range, because the takeover has already reset the price benchmark.
