The disclosure on page 69 of the Proxy Statement/Prospectus is hereby amended by replacing the paragraph under the heading “Discounted Cash Flow Analysis” on such page with the following:

Rothschild performed a discounted cash flow analysis, which calculates an implied value per share by discounting to the present the value of unlevered free cash flow for 2018 to 2024, based on the KapStone forecasts, assuming the tax changes and the price increases, and adding thereto a terminal value for KapStone calculated based on terminal free cash flows of approximately $302 million using a range of terminal growth rates from 2.0% to 3.0%. In its analysis, Rothschild utilized a range of discount rates from 8.5% to 9.5%, which was selected based on the estimated weighted average cost of capital of KapStone. The foregoing analysis indicated an approximate implied value per KapStone share reference range of$22.00 to $32.00, as compared to the KapStone cash consideration of $35.00 per KapStone share.

The disclosure on page 70 of the Proxy Statement/Prospectus is hereby amended by replacing the second bullet point on such page with the following:

· the present value of the future price of KapStone shares (referred to as the PV of future KapStone share price) implied by KapStone’s projected EBITDA and net debt for 2019 and 2020, based on the KapStone forecasts, which net debt for 2019 and 2020 was $1,092 million and $860 million, respectively, discounted at a rate of 12.2%, which was selected based on the estimated cost of equity of KapStone; this methodology implied an approximate implied value per KapStone share reference range of $30.00 to $36.00; and

The disclosure on page 72 of the Proxy Statement/Prospectus is hereby amended by adding the following paragraph immediately after the fourth full paragraph on such page:

Throughout the following summary, references to KapStone’s EBITDA are to KapStone’s Adjusted EBITDA as included in the 2018-2024 forecasts provided to Moelis by KapStone’s management (such 2018-2014 forecasts are more fully described in the section entitled “—Certain KapStone Forecasts” beginning on page 96).

The following disclosure supplements and restates the final full paragraph on page 75 of the Proxy Statement/Prospectus by replacing such paragraph with the following:

Based on the foregoing analysis and its professional judgment and experience, Moelis applied a selected multiple range of 8.0x to 10.5x KapStone’s 2017 calendar year EBITDA using financial information and data provided by KapStone’s management. This resulted in a reference range of $20.55 to $31.22 per KapStone share, as compared to the KapStone cash consideration of $35.00 per KapStone share.

The following disclosure supplements and restates the final paragraph on page 75 of the Proxy Statement/Prospectus by adding the underlined text:

Discounted Cash Flow Analysis. Moelis performed a discounted cash flow (referred to as DCF) analysis using the 2018—2024 forecasts provided by KapStone’s management to calculate the estimated present value of the future unlevered after-tax free cash flows projected to be generated by KapStone, including terminal free cash flows. Moelis (i) treated KapStone management’s estimates for stock-based compensation as a cash expense for purposes of the DCF analysis and (ii) reflected KapStone management’s estimated tax rate of 24% in all periods, taking into account KapStone management’s estimate of the impact of recently enacted tax legislation. In performing the DCF analysis, Moelis utilized a range of discount rates of 8.75% to 10.75% based on an estimated range of KapStone’s weighted average cost of capital (referred to as WACC). The WACC range reflected a derived cost of equity using (i) a selected range of betas and debt to total capitalization ratios informed by the selected public companies and KapStone’s own statistics as of January 26, 2018 and (ii) a size premium based on companies with equity values similar to KapStone. Moelis noted that the data underlying the WACC calculations pre-dates (and/or does not reflect the impact of) recently enacted federal tax legislation. The foregoing range of discount rates was used to calculate estimated present values as of December 31, 2017 of (i) KapStone’s estimated after-tax unlevered free cash flows for fiscal years ending December 2018 to 2024 and (ii) a range of estimated terminal values derived by applying a range of perpetuity growth rates of 2.0% to 3.0% to KapStone’s terminal unlevered free cash flow projection of approximately $302 million. The perpetuity growth rate range was informed by (i) KapStone management’s assumptions for industry price and volume growth, (ii) implied terminal EBITDA multiples of 6.4x to 9.6x reflecting recent and historical trading multiples of the selected public companies and (iii) long-term GDP growth. Terminal free cash flow was calculated by KapStone’s management as fiscal year 2024 unlevered free cash flow adjusted to reflect normalized levels for changes in working capital and depreciation, and to eliminate tax deductible amortization which ceases in fiscal year 2029 (with the tax benefit of deductible amortization in fiscal year 2025 — 2029 separately calculated and included in the derived DCF per share values).

The disclosure on pages 98 and 99 of the Proxy Statement/Prospectus is hereby amended by replacing the table set forth on page 98 (including the footnotes thereto), the last paragraph on page 98 and the first paragraph on page 99 with the following:

(1) EBITDA is defined as earnings before interest expense, income taxes, depreciation and amortization.

(2) In connection with their respective discounted cash flow analyses and as summarized in the table above, at the direction of the KapStone board and management, each of Rothschild and Moelis used unlevered free cash flows based upon the 2018-2024 forecasts.

Non-GAAP Financial Measures

Certain of the financial forecasts are non-GAAP financial measures, including EBITDA, Adjusted EBITDA, Re-Adjusted EBITDA, Adjusted EBIT, Tax Effected EBIT and Unlevered Free Cash Flow. Non-GAAP financial measures should not be considered in isolated form or as a substitute for financial information presented in compliance with GAAP, and non-GAAP financial measures as used by KapStone may not be comparable to similarly titled financial measures used by other companies.

KapStone management uses these non-GAAP financial measures to focus on KapStone’s on-going operations, and believes they are useful to investors because they enable investors to perform meaningful comparisons of past and present operating results. KapStone believes that EBITDA and Adjusted EBITDA provide useful information to investors because they improve the comparability of the financial results between periods and provide for greater transparency to key measures used to evaluate the performance of KapStone. KapStone management uses Adjusted EBITDA for evaluating its performance against competitors and as a primary measure for employees’ incentive programs.
