Exhibit 99.1

KEYCORP PROVIDES NOTICE OF REDEMPTION OF SERIES C PREFERRED STOCK

CLEVELAND, January 12, 2017 – KeyCorp (NYSE: KEY) announced today that it has provided notice of its intention to redeem all outstanding shares of its Fixed-to-Floating Rate Perpetual Non-Cumulative Preferred Stock, Series C (NYSE: KEY.H) (the “Preferred Stock”) on February 15, 2017.

There are 14 million shares of Preferred Stock, with an aggregate liquidation preference of $350 million, currently outstanding. The Preferred Stock, issued in connection with KeyCorp’s 2016 acquisition of First Niagara Financial Group, Inc. to replace First Niagara’s preferred stock, will be redeemed for cash at a redemption price of $25 per share. Since the redemption date for the Preferred Stock is also a dividend payment date, the redemption price of $25 per share does not include any declared and unpaid dividends. Declared dividends of $.539063 per share, which were declared by the Board of Directors today, for the full current quarterly dividend period from and including November 15, 2016 to but excluding February 15, 2017 will be paid separately in the customary manner on February 15, 2017 to holders of record on February 3, 2017. All shares of the Preferred Stock are held in book-entry form through the Depository Trust Company (“DTC”) and will be redeemed in accordance with the procedures of DTC. Upon redemption, the Preferred Stock will no longer be outstanding and all rights with respect to such stock will cease and terminate, except the right to payment of the redemption price. Also upon redemption, the Preferred Stock will be delisted from trading on the New York Stock Exchange.

Computershare, KeyCorp’s transfer agent, will serve as the redemption agent. Computershare is located at 250 Royall Street, Canton, MA 02021.
