 may be obtained from us upon request and in the manner described in the section entitled “Where You Can Find More Information.” We may amend the form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement at any time and from time to time by agreement with the depositary. However, any amendment that materially and adversely alters any right of the holders of depositary shares will not be effective unless the holders of at least two-thirds ofthe depositary shares then outstanding approve the amendment. We will make no amendment that impairs the right of any holder of depositary shares to surrender such depositary shares to the depositary with instructions to deliver to such holder shares of the Series B Preferred Stock, except in order to comply with mandatory provisions of applicable law. Holders who retain or acquire their depositary receipts after an amendment becomes effective will be deemed to have agreed to the amendment and will be bound by the amended deposit agreement. The deposit agreement may be terminated if:

| • |     | all outstanding depositary shares have been redeemed; |

| • |     | a final distribution in respect of the Series B Preferred Stock has been made to the holders of depositary shares 
 in connection with any liquidation, dissolution or winding up of Wesbanco; or                                     |

| • |     | consent of the holders of at least two-thirds of the depositary shares 
 outstanding is obtained.                                               |

In this prospectus supplement, references to “holders” of the depositary shares mean those who have the depositary shares registered in their own names, on the books that we or the depositary maintain for this purpose, and not indirect holders who own beneficial interests in the depositary shares registered in the street name of or issued in book-entry form through DTC. Please review the special considerations that apply to indirect holders S-34

described in the “Book-Entry, Delivery and Form of Depositary Shares” section of this prospectus supplement beginning on page S-37.
