 Preferred Stock, as described under “Description of Depositary Shares.”

The following is a brief
description of the material terms of the Series B Preferred Stock. The following summary of the terms and provisions of the Series B Preferred Stock does not purport to be complete in all respects, and is qualified in its entirety by reference to
the pertinent sections of our Restated Certificate of Incorporation, as amended (our “Certificate of Incorporation”), including the certificate of designations creating the Series B Preferred Stock, which will be filed as an exhibit to a
Current Report on Form 8-K, and the applicable provisions of the Delaware General Corporation Law.

General

Under our Certificate of Incorporation, our board of directors is authorized to issue up to 10,000,000 shares of preferred stock in
one or more series. Our board of directors is expressly authorized to provide for the issuance from time to time of shares of preferred stock in one or more series, with such voting powers, full or limited but not to exceed one vote per share, or
without voting powers, and with such designations, preferences and relative, participating, optional or other special rights, and qualifications, limitations or restrictions thereof, as the board of directors (or a duly authorized committee thereof)
may determine.

The Series B Preferred Stock will be a single series of our authorized preferred stock. Prior to the issuance of the
Series B Preferred Stock, we will file the certificate of designations with respect to the Series B Preferred Stock with the Secretary of State of the State of Delaware. When issued, the Series B Preferred Stock will be fully paid and non-assessable. As of the date of this prospectus supplement, we have no outstanding shares of preferred stock.

The Series B Preferred Stock will not be convertible into, or exchangeable for, shares of any other class or series of stock or other
securities of Comerica. The Series B Preferred Stock will not have any maturity date and will not be subject to any sinking fund or other obligation of us to redeem or repurchase the Series B Preferred Stock.

Shares of Series B Preferred Stock that are redeemed, purchased or otherwise acquired by us will be cancelled and will revert to authorized
but unissued shares of preferred stock undesignated as to series.

The Series B Preferred Stock represents
non-withdrawable capital, will not be an account of an insurable type, and will not be insured or guaranteed by the FDIC or any other governmental agency or instrumentality.
