2017 Second Quarter Earnings Call May 4, 2017 www.BECN.com 13 19.8% of Sales Adjusted Net Income (Loss) is defined as net income excluding certain non - recurring costs and the incremental amortization of acquired intangibles related to major acquisitions completed in fiscal years 2016 and 2017. We believe that Adjusted Net Income (Loss) is an operating performance metric that is useful to investors because it permits investors to better understand year - over - year changes in underlying operating performance. Adjusted net income per share or “Adjusted EPS” is calculated by dividing the Adjusted Net Income (Loss) for the period by the weighted - average diluted shares outstanding for the period. Non - GAAP Adjustments are comprised entirely of non - recurring costs related to major acquisitions completed in fiscal years 2016 and 2017 - See "RSG and Other Fiscal 2016 - 2017 Acquisition Costs" slide for further detail. While we believe Adjusted Net Income (Loss) and Adjusted EPS are useful measures for investors, these are not measurements presented in accordance with United States Gen era lly Accepted Accounting Principles (“GAAP”). You should not consider Adjusted Net Income (Loss) or Adjusted EPS in isolation or as a substitute for net income and net loss per share or diluted earnings per share calculate d i n accordance with GAAP.

2017 Second Quarter Earnings Call May 4, 2017 www.BECN.com 15 Adjusted EBITDA is defined as net income plus interest expense (net of interest income), income taxes, depreciation and amort iza tion, adjustments to contingent consideration, stock - based compensation and certain non - recurring costs from major acquisitions completed in fiscal years 2016 and 2017. We believe that Adjusted EBITDA is an operating performance measure that provides in ves tors and analysts with a measure of operating results unaffected by differences in capital structures, capital investment cycles, and ages of related assets amon g o therwise comparable companies. Acquisition costs reflect certain non - recurring charges related to major acquisitions completed in fiscal years 2016 and 2017 (excluding the impact of tax) that are not embedded in other balances of the table. Cer tain portions of the total acquisition costs incurred are included in interest expense, income taxes, depreciation and amortizatio n, and stock - based compensation. While we believe Adjusted EBITDA is a useful measure for investors, it is not a measurement presented in accordance GAAP. You sh ould not consider Adjusted EBITDA in isolation or as a substitute for net income, cash flows from operations, or any other items calculated in accordance with GAAP. In addition, Adjusted EBITDA has inherent mat erial limitations as a performance measure. It does not include interest expense. Because we have borrowed money, interest expense is a necessary element of our costs. In addition, Adjusted EBITDA does not i ncl ude depreciation and amortization expense. Because we have capital and intangible assets, depreciation and amortization expense is a necessary element of our costs. Adjusted EBITDA also does not i ncl ude stock - based compensation, which is a necessary element of our costs because we make stock awards to key members of management as an important incentive to maximize overall company performance and as a ben efit. Moreover, Adjusted EBITDA does not include taxes, and payment of taxes is a necessary element of our operations. Accordingly, since Adjusted EBITDA excludes these items, it has material limi tat ions as a performance measure. We separately monitor capital expenditures, which impact depreciation expense, as well as amortization expense, interest expense, stock - based compensation expense, and income tax expense. Because not all companies use identical calculations, our presentation of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies.
