Kaskela Law has is investigating the fairness of the recently announced proposed acquisition of Comerica Inc. (NYSE: CMA) to determine whether the as-proposed stock exchange ratio undervalues Comerica’s shares.

On October 6, 2025, Comerica announced that it had agreed to be acquired by Fifth Third Bancorp.  According to the announcement, Comerica stockholders are expected to receive 1.8663 shares of Fifth Third stock for each Comerica share that they own at the time the transaction closes.

The investigation seeks to determine whether Comerica investors will be receiving sufficient financial consideration for their shares, and whether the company’s officers and/or directors breached their fiduciary duties or violated the securities laws in agreeing to the proposed 1.8663/share exchange ratio with Fifth Third.

Comerica shareholders who purchased or acquired their CMA shares prior to July 1, 2025 are encouraged to contact Kaskela Law LLC (D.
