Item 2.02 Results of Operations And Financial Condition.

On July 20, 2017, Capital Bank Financial Corp. (the “Company”) issued a press release announcing its financial results for the second quarter of 2017. A copy of the press release is furnished as Exhibit 99.1 herewith and is incorporated herein by reference.

Item 8.01 Other Events.

~~Filed~~As aspreviously ~~Exhibit~~announced, 99First Horizon National Corporation ("First Horizon") and Capital Bank Financial Corp.1 is("Capital Bank Financial") entered into an agreement and plan of merger, dated May 3, 2017, between First Horizon, Capital Bank Financial and Firestone Sub, Inc., a ~~copy~~Delaware corporation and direct wholly-owned subsidiary of First Horizon, pursuant to which and on the ~~Company's~~terms ~~earnings~~and ~~release~~subject ~~for~~to the ~~quarter~~conditions ~~ended~~set ~~June~~forth 30therein, ~~2017~~Capital Bank Financial will merge with and into First Horizon, ~~which~~with First Horizon as the surviving corporation in the merger. The proposed merger is ~~scheduled~~described toin bethe ~~released~~Joint Proxy Statement/Prospectus filed on July 2028, 2017 in connection with the merger (the "Joint Proxy Statement/Prospectus"). This Current Report on Form 8-K provides certain additional information regarding the merger.

As previously disclosed in the Joint Proxy Statement/Prospectus, Capital Bank Financial and the individual members of the Capital Bank Financial board of directors have been named as defendants in three substantially similar putative class action lawsuits filed by alleged shareholders of Capital Bank Financial.

These actions are captioned: (1) Bushansky v. Capital Bank Financial Corp., et al., No. 3:17-cv-00422 (W.D. North Carolina filed July 17, 2017); (2) Parshall v. Capital Bank Financial Corp., et al., No. 3:17-cv-00428 (W.D. North Carolina filed July 19, 2017); and (3) Catherine McNamara v. Capital Bank Financial Corp., et al., No. 3:17-cv-00439 (W.D. North Carolina filed July 25, 2017). The Parshall complaint also names First Horizon and Firestone Sub, Inc. as defendants. The three complaints allege, among other things, that the defendants violated Section 14(a) and Section 20(a) of the Securities Exchange Act and Rule 14a-9 promulgated thereunder by not disclosing certain allegedly material facts in the registration statement on Form S-4 filed on June 29, 2017, which renders it false and misleading. On August 11, 2017, the court ordered the consolidation of the three lawsuits into the lead action captioned In Re: Capital Bank Financial Corp. Stockholder Litigation, No. 3:17-cv-00422.

Capital Bank Financial believes that no further supplemental disclosure is required under applicable law; however, to avoid the burden and expense of further litigation and to avoid the risk that the consolidated action may delay or otherwise adversely affect the consummation of the merger, Capital Bank Financial wishes to voluntarily make the supplemental disclosures related to the proposed merger set forth below.

Supplemental Disclosures

The following materials supplement the statements contained in the Joint Proxy Statement/Prospectus and should be read in conjunction with those statements in their entirety. To the extent the information set forth herein differs from or updates information contained in the Joint Proxy Statement/Prospectus, the information set forth herein shall supersede or supplement the information in the Joint Proxy Statement/Prospectus. Nothing in this Current Report shall be deemed an admission of the legal necessity or materiality of the disclosures set forth herein, either separately or taken together. All page references are to pages in the Joint Proxy Statement/Prospectus, and terms used below, unless otherwise defined, have the meanings set forth in the Proxy Statement.

The disclosure in the seventh paragraph on page 59 of the Joint Proxy Statement/Prospectus under the heading "The Mergers – Background of the Merger" is hereby amended and restated to read:

On April 17, 2017, Sullivan & Cromwell LLP, First Horizon's legal counsel, provided Wachtell Lipton a draft merger agreement, which provided, among other things, that First Horizon would appoint Mr. Taylor and one additional member of the Capital Bank Financial board of directors, to be mutually agreed by Capital Bank Financial and First Horizon prior to Closing, to the board of directors of the combined company following the merger. The parties began to negotiate transaction documentation simultaneously with the ongoing due diligence investigations. Subsequently, on April 23, 2017, Wachtell Lipton provided Sullivan & Cromwell a revised draft merger agreement which, among other things, provided for an election between cash consideration and stock consideration.

The disclosure in the fourth paragraph on page 60 of the Joint Proxy Statement/Prospectus under the heading "The Mergers – Background of the Merger" is hereby amended and restated to read:

First Horizon had indicated in its initial indication of interest to Capital Bank that First Horizon desired for Mr. Taylor to have a significant role with the combined company. They decided to defer serious discussions regarding Mr. Taylor's employment until the corporate negotiations were substantially complete. On May 1, 2017, Sullivan & Cromwell provided Wachtell Lipton a draft employment agreement between First Horizon and Mr. Taylor providing for the terms of Mr. Taylor's employment by First Horizon following the completion of a transaction. The parties and their respective advisors discussed and negotiated the terms of the draft agreement.

The following disclosure is hereby added immediately prior to the penultimate paragraph on page 72 of the Joint Proxy Statement/Prospectus under the heading "Opinion of Capital Bank Financial's Financial Advisor":

Net Present Value Analyses. Sandler O'Neill performed an analysis that estimated the net present value per share of Capital Bank Financial common stock, assuming Capital Bank Financial performed in accordance with publicly available mean analyst earnings estimates for Capital Bank Financial for the years ending December 31, 2017 and December 31, 2018 of $1.91 and $2.22, respectively, and an annual earnings per share growth rate of 10% thereafter based on publicly available mean analyst estimated long-term annual earnings per share growth rates, as well as dividend assumptions for Capital Bank Financial, as provided by the senior management of Capital Bank Financial, of $0.50 for the year ending December 31, 2017, $0.57 for the year ending December 31, 2018, $0.63 for the year ending December 31, 2019, $0.69 for the year ending December 31, 2020 and $0.76 for the year ending December 31, 2021. To approximate the terminal value of Capital Bank Financial common stock at December 31, 2021, Sandler O'Neill applied price to 2021 earnings multiples ranging from 18.0x to 22.0x and multiples of December 31, 2021 tangible book value ranging from 180% to 220%. The terminal values were then discounted to present values using different discount rates ranging from 8.0% to 13.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Capital Bank Financial common stock. Sandler O'Neill utilized the equity build-up method to calculate the appropriate discount rate for Capital Bank Financial common stock. As detailed in the following table, which sets forth the calculation of the 10.00% discount rate utilized by Sandler O'Neill in certain of its net present value analyses, the discount rate equals the sum of the risk free rate, the equity risk premium, the size premium and the industry premium.

Risk free rate 2.29%

Equity risk premium 5.80%

Size Premium 1.00%

Industry Premium 0.91%

Discount Rate 10.00%

The risk free rate is represented as the yield on the 10-year U.S. Treasury note as of May 2, 2017. The equity risk premium, size premium and industry premium were sourced from the Duff & Phelps 2016 Valuation Handbook. As illustrated in the following tables, the analysis indicated an imputed range of values per share of Capital Bank Financial common stock of $31.83 to $47.46 when applying multiples of earnings and $31.99 to $47.67 when applying multiples of tangible book value.

Sandler O'Neill also performed an analysis that estimated the net present value per share of First Horizon common stock, assuming that First Horizon performed in accordance with publicly available mean analyst earnings per share estimates for First Horizon for the years ending December 31, 2017 and December 31, 2018 of $1.11 and $1.30, respectively, as provided by the senior management of First Horizon, and a publicly available mean analyst estimated long-term annual earnings per share growth rate for First Horizon of 7%, as directed by the senior management of Capital Bank Financial. To approximate the terminal value of First Horizon common stock at December 31, 2021, Sandler O'Neill applied price to 2021 earnings multiples ranging from 17.0x to 21.0x and multiples of December 31, 2021 tangible book value ranging from 190% to 230%. The terminal values were then discounted to present values using different discount rates ranging from 8.0% to 13.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of First Horizon common stock. Sandler O'Neill utilized the equity build-up method to calculate the appropriate discount rate for First Horizon common stock.

The disclosure in the first full sentence on page 78 of the Joint Proxy Statement/Prospectus under the heading "Opinion of Capital Bank Financial's Financial Advisor – Pro Forma Merger Analysis" is hereby amended and restated to read:

The analysis indicated that the merger could be accretive to First Horizon's earnings per share (excluding one-time transaction costs and expenses) in the years ending December 31, 2018, December 31, 2019 and December 31, 2020 by 5.6%, 7.9% and 8.5%, respectively, and dilutive to First Horizon's estimated tangible book value per share at closing by 10.1% and at December 31, 2018, December 31, 2019 and December 31, 2020 by 8.7%, 6.4% and 4.4%, respectively.
