M&T Bank traces its origins to the founding of Manufacturers and Traders Bank in Buffalo, New York. As a result of mergers, acquisitions and name changes, M&T Bank Corporation's principal bank is now known as Manufacturers and Traders Trust Company, or M&T Bank. M&T Bank reorganized under a bank holding company in 1969 called First Empire State Corporation. The name was changed in 1998 to M&T Bank Corporation, whose common stock is listed on the New York Stock Exchange and trades under the symbol "MTB."
Following the April 1, 2022 merger with People’s United Financial, Inc., M&T Bank has a network of over 1,000 branches and 2,200 ATMs that span 12 states from Maine to Virginia and Washington, D.C.
