Exhibit 99.1

First Horizon and Capital Bank Financial Announce

Election Deadline for Capital Bank Financial Stockholders to Elect

Merger Consideration and Expected Closing Date

MEMPHIS, Tenn. and CHARLOTTE, NC. – November 17, 2017 – First Horizon National Corporation (NYSE: FHN) ("First Horizon") and Capital Bank Financial Corp. (NASDAQ: CBF) ("Capital Bank Financial") today announced that the "Election Deadline" (as defined in the election materials previously provided to Capital Bank Financial stockholders of record) is 5:00 p.m. CST on November 28, 2017. The Election Deadline is based on the parties' current expectation that the merger transaction will be completed on November 30, 2017. However, the completion of the transaction remains subject to the satisfaction or waiver of certain conditions contained in the parties' Agreement and Plan of Merger, dated as of May 3, 2017 (the "Merger Agreement").

The Election Deadline, as provided in the Merger Agreement, is the deadline by which stockholders of record of Capital Bank Financial may elect to receive cash, shares of First Horizon common stock, or both as "merger consideration" in connection with the parties' proposed merger. The Election Deadline may be extended, in which case First Horizon and Capital Bank Financial will announce the new Election Deadline by issuing another press release.

Capital Bank Financial stockholders of record wishing to make an election must deliver to Wells Fargo Bank, N.A. (the "Exchange Agent"), a properly completed Letter of Election and Transmittal and any other applicable election materials, by the Election Deadline of 5:00 p.m. CST on November 28, 2017 (unless extended). The election materials do not provide for a guaranteed delivery procedure. Capital Bank Financial stockholders who hold their shares through a bank, broker or other nominee may be subject to an earlier deadline than the Election Deadline for making their elections, based on the instructions of their brokers, banks or other nominees. Capital Bank Financial stockholders bear the risk of ensuring proper and timely delivery of their election materials.

Capital Bank Financial stockholders may elect to receive, with respect to each share of Capital Bank Financial common stock held, either (i) an amount in cash equal to the sum, rounded to the nearest one-tenth of a cent, of (A) $7.90 plus (B) the product of 1.75 multiplied by the average of the closing sale prices of a share of First Horizon common stock on the New York Stock Exchange, for the ten full trading days ending on the day preceding the closing date of the merger (the "First Horizon Share Closing Price"), or (ii) the number of shares of First Horizon common stock equal to the quotient, rounded to the nearest ten thousandth, of (A) cash consideration divided by (B) the First Horizon Share Closing Price, subject to the procedures applicable to oversubscription and undersubscription for cash consideration set forth in the Merger Agreement. As a result, stockholders who elect to receive entirely cash or entirely stock may receive a combination of cash and First Horizon common stock, and stockholders who elect to receive a combination of cash and stock may receive cash and First Horizon common stock in a different proportion from what they elected.

Stockholders who do not submit properly completed election materials to the Exchange Agent by the Election Deadline will be deemed to have made no election with respect to their shares of Capital Bank Financial common stock. Such shares will be converted into the right to receive the stock consideration or the cash consideration according to the allocation procedures specified in the Merger Agreement. After Capital Bank Financial stockholders have made their elections and tendered their shares of Capital Bank Financial common stock to the Exchange Agent, they will be unable to sell or transfer their shares of Capital Bank Financial common stock unless they revoke their election prior to the Election Deadline.

All of the documents necessary to make an election were previously mailed to Capital Bank Financial stockholders of record as of October 13, 2017. Capital Bank Financial stockholders of record may obtain additional copies of the election materials by contacting Morrow Sodali LLC at (800) 414-4313. Capital Bank Financial stockholders who hold their shares in "street name" may obtain additional copies of the election materials by contacting their bank, broker or other nominee.

A more detailed description of the merger consideration and the allocation and proration procedures applicable to elections is contained in the Joint Proxy Statement/Prospectus dated July 28, 2017. Capital Bank Financial stockholders are urged to read the Joint Proxy Statement/Prospectus carefully and in its entirety.
