KeyCorp will review its performance and strategy, including the performance and strategy of Key Corporate Bank, at the Bank of America Merrill Lynch 2013 Banking and Financial Services Conference on November 12, 2013. A copy of the slides forming the basis of the presentation is attached hereto as Exhibit 99.1 and will be posted on KeyCorp’s website in connection with the conference. These slides are also expected to be provided or referred to at related investor events on November 12, 2013.

The information in this Item 7.01 and Exhibit 99.1 attached hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities under that Section, nor shall it be deemed incorporated by reference into the filings of KeyCorp under the Securities Act of 1933, as amended.

This current report on Form 8-K (including the Exhibit attached hereto) contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are not historical facts but instead represent management’s current expectations and forecasts regarding future events, many of which, by their nature, are inherently uncertain and outside of KeyCorp’s control. KeyCorp’s actual results may differ, possibly materially, from those set forth in the forward-looking statements. Factors that could cause actual results to differ materially from those described in the forward-looking statements can be found in KeyCorp’s Annual Report on Form 10-K for the year ended December 31, 2012, and its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2013, June 30, 2013 and September 30, 2013, each of which has been filed with the U.S. Securities and Exchange Commission and is available on Key’s website (www.key.com/ir) and on the Securities and Exchange Commission’s website (www.sec.gov). Key does not undertake to update the forward-looking statements to reflect the impact of circumstances or events that may arise after the date of the forward-looking statements.
