(1) The information presented in the table above regarding adjusted cost of sales, gross profit, operating income, depreciation and amortization expense and adjusted earnings before interest, taxes, depreciation, and amortization (“Adjusted EBITDA”), and Adjusted EBITDA margin does not conform to GAAP.  This information should not be construed as an alternative to the reported results determined in accordance with GAAP. Management has included this non-GAAP information to assist in understanding the operating performance of the Company as well as the comparability of the Company’s financial results. The non-GAAP information provided may not be consistent with the methodologies used by other companies. Non-GAAP depreciation and amortization expense, Adjusted EBITDA and Adjusted EBITDA margin are reconciled with reported GAAP results in the tables beginning on page 3 of this Exhibit 99.1.  As noted above, Adjusted EBITDA and Adjusted EBITDA margin are non-GAAP financial measures. Adjusted EBITDA excludes costs associated with various activities of the Company including the following: organizational realignment costs to support the 2020 strategic plan as announced in December 2016; restructuring costs in EIMEA related to operational efficiency improvement projects; expenses regarding combining Construction Products facilities in Illinois; Project ONE development costs; integrating and accounting for acquisition expenses; and all transaction-related costs of the Royal Adhesives Acquisition. Adjusted EBITDA margin is defined as Adjusted EBITDA divided by net revenue.  Adjusted cost of sales reflects reported GAAP results, excluding costs associated with various activities of the Company as previously disclosed in each of the Company's Current Reports on Form 8-K filed on March 30, 2017, June 29, 2017, September 28, 2017 and January 24, 2018, respectively.  Adjusted gross profit is defined as net revenue less adjusted cost of sales.  Segment operating income is defined as gross profit less selling, general and administrative expenses.  Adjusted segment operating income reflects reported GAAP results, as shown on page 2 of this Exhibit 99.1, including the adjustments made to arrive at Adjusted EBITDA shown in the tables beginning on page 3 of this Exhibit 99.1.
