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:
