New York, Feb 5, 2026, 13:01 EST — Regular session
- After the Fifth Third deal closed, Comerica shares were suspended and removed from NYSE trading.
- Each Comerica share converted into the right to 1.8663 shares of Fifth Third, with cash paid out for any fractions.
- Now that CMA is out, the focus shifts to price moves in Fifth Third and the broader regional bank sector.
Comerica’s CMA shares have stopped trading following Fifth Third Bancorp’s completion of its acquisition, with Comerica stock now swapped for Fifth Third shares, a recent filing shows. The company asked the NYSE to halt trading and delist Comerica before the market opened on Feb. 2. Additionally, Fifth Third intends to deregister Comerica’s securities and cease related reporting requirements.
For investors, this means Comerica no longer trades under its own ticker. Shares in CMA have effectively converted into Fifth Third stock, so the value of what used to be a Comerica holding now moves in lockstep with Fifth Third’s price.
This comes at a sensitive point for the tape. Regional bank stocks often react sharply to shifts in interest-rate expectations, as rate changes directly impact banks’ earnings on loans versus their costs on deposits.
Shares of Fifth Third slipped around 0.6% to $53.79 by midday, with the SPDR S&P Regional Banking ETF dropping 0.3%. KeyCorp barely moved, and Huntington Bancshares edged down about 0.2%. Based on Fifth Third’s current price, the fixed exchange ratio values each former Comerica share at approximately $100.39 in Fifth Third stock.
Comerica’s most recent trade came in at $88.67 late on Jan. 30, marking a roughly 2.6% drop from the previous close, according to market data.
Credit markets are also seeing some cleanup. Fitch withdrew Comerica’s ratings following its acquisition by Fifth Third, which closed on Feb. 1.
Rates continue to dominate the narrative for bank stocks. Investors are increasingly placing bets on a steeper U.S. Treasury yield curve with Kevin Warsh set to take over as Federal Reserve Chair. One fund manager told Reuters this will likely lead to “a yield curve that is more normally positively sloped.” A steeper curve tends to boost banks’ net interest margin — the gap between earnings on assets and funding costs — but it can also raise red flags around inflation and deficit concerns.

The neat “conversion is done” narrative might hit some bumps, though. Slip-ups in integration, costs running hotter than forecast, or a dip in credit quality could weigh on Fifth Third’s stock, directly impacting former Comerica shareholders.
For now, the focus is on operational milestones, not the stock. Fifth Third CEO Tim Spence told The Dallas Morning News that the bank plans to complete its systems conversions over Labor Day weekend. Comerica branches will keep operating under the Comerica name until the tech integration is finished.
