Wilmington Trust announces further steps towards completion
of M&T Bank merger

Wilmington, Del., April 20, 2011 — Wilmington Trust Corporation (Wilmington Trust) (NYSE: WL) announced today that, in connection with its planning for the anticipated closing of its merger with M&T Bank Corporation (M&T), it has notified the New York Stock Exchange (NYSE) that it intends to seek voluntary withdrawal from listing on the NYSE of its common stock, par value $1.00 per share, which would be effective upon closing of the merger. The completion of the merger remains subject to the terms and conditions of the merger agreement between Wilmington Trust and M&T, including the receipt of regulatory approvals. Following the merger’s completion, which is expected to occur in the 2011 second quarter, Wilmington Trust will be a wholly owned subsidiary of M&T.

If the delisting becomes effective, Wilmington Trust’s common stock would cease to be listed on the NYSE, or any other stock exchange or quotation system, and upon application to the Securities and Exchange Commission, will be deregistered under the Securities and Exchange Act of 1934, as amended.

Under the terms of the merger agreement, upon the closing of the merger, Wilmington Trust’s stockholders will be entitled to receive 0.051372 of a share of M&T common stock for each share of Wilmington Trust common stock. The shares of M&T common stock to be issued in the merger to Wilmington Trust stockholders have been approved for listing on the NYSE, subject to official notice of issuance.
