Exhibit 99.1

KeyCorp, Department of Justice, and Federal Reserve Board Agree on First Niagara Branch Divestitures

Key to Sell 18 First Niagara Locations and $1.7 Billion in Deposits to Northwest Bank

CLEVELAND, Ohio –April 28, 2016 – KeyCorp (NYSE: KEY) and First Niagara Financial Group, Inc. (NASDAQ: FNFG) announced today that they have reached an agreement with Northwest Bank, a wholly-owned subsidiary of Northwest Bancshares, Inc. (NASDAQGS: NWBI), to sell 18 branches in the Buffalo Federal Reserve banking market totaling $1.7 billion in deposits and $0.5 billion in loans. Northwest Bank’s purchase includes all 18 branches slated for divestiture under Key’s agreements with the United States Department of Justice (DOJ) and the Federal Reserve Board, which were entered into in connection with their review of KeyCorp’s pending merger with First Niagara. Key will retain its middle market, private banking, municipal and commercial real estate client relationships within this market. The divestiture transaction is subject to the completion of the merger of KeyCorp and First Niagara, which remains subject to regulatory approvals.

Northwest Bank has approximately $9 billion of total assets and has a 15-year history of operations in the Buffalo market. Since its initial public offering in 1994, Northwest has completed over 37 bank transactions including 14 branch purchases. It is expected that personnel associated with the divested locations will join Northwest Bank upon completion of the divestitures.

“Today’s announcement is another important milestone for the KeyCorp and First Niagara merger, which remains on-track to close in the third quarter of this year,” said Beth Mooney, Chairman and CEO of KeyCorp. “We are pleased to reach agreement for Northwest Bank to acquire these branches. We will be working closely with Northwest in the coming months to deliver a seamless transition for clients and communities.”

As announced in October 2015, the combination of Key and First Niagara will create a leading regional bank with enhanced scale to serve three million clients across diverse markets in the Northeast, Mid-Atlantic, Midwest and Pacific Northwest. The acquisition will make KeyBank a leading bank in Upstate New York, with a strong market presence in Buffalo, Albany, Syracuse and Rochester. KeyBank will also expand its operations to attractive markets throughout Pennsylvania, Massachusetts and Connecticut.
