Forward-Looking Statements This webcast and presentation contain statements that are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include all statements that do not relate solely to historical or current facts and can generally be identified by the use of future dates or words such as "may," "should," "could," “will,” "expects," "seeks to," "anticipates," "plans," "believes," "estimates," "intends," "predicts," "projects," "potential" or "continue" or the negative of such terms and other comparable terminology. These statements also include, but are not limited to, the 2017 outlook included herein, and the Company’s strategic and operational initiatives, including obtaining integration synergies, product mix and overall cost improvement and are based on current expectations, estimates, and projections about the Company's business based, in part, on assumptions made by management. These statements are not guarantees of future performance and involve risks, uncertainties and assumptions that are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements due to numerous factors, risks, and uncertainties discussed in the Company's Securities and Exchange Commission filings and reports, including the Company's Annual Report on Form 10-K for the year-ended December 25, 2016, Quarterly Reports on Form 10-Q and other reports from time to time filed with the Securities and Exchange Commission. You are cautioned not to unduly rely on such forward looking statements when evaluating the information presented in this press release. Such forward-looking statements speak only as of the date on which they are made and the Company does not undertake any obligation to update any forward-looking statement to reflect events or circumstances after the date of this webcast and presentation. Use of Non-GAAP Financial Measures In addition to the results reported in accordance with GAAP included throughout this presentation, this presentation refers to “Adjusted EBITDA,” which we have defined as earnings before interest, taxes, depreciation, amortization, restructuring charges and impairments of long-lived assets and investments and “Value-Added Sales,” which we define as net sales less pass-through charges primarily for the value of aluminum. Adjusted EBITDA as a percentage of value-added sales is a key measure that is not calculated according to GAAP. Adjusted EBITDA as a percentage of value-added sales is defined as adjusted EBITDA divided by value-added sales. Management believes the non-GAAP financial measures used in this presentation are useful to both management and investors in their analysis of the Company’s financial position and results of operations. Further, management uses these non-GAAP financial measures for planning and forecasting future periods. This non-GAAP financial information is provided as additional information for investors and is not in accordance with or an alternative to GAAP. These non-GAAP measures may be different from similar measures used by other companies. For reconciliations of these non-GAAP financial measures to the most directly comparable financial measures calculated and presented in accordance with GAAP, see the appendix of this presentation. In reliance on the safe harbor provided under section 10(e) or Regulation S-K, we have not quantitatively reconciled differences between adjusted EBITDA presented in our 2017 Outlook to net income, the most comparable GAAP measure, as Superior is unable to quantify certain amounts that would be required to be included in net income without unreasonable efforts and due to the inherent uncertainty regarding such variables. Superior also believes that such a reconciliation would imply a degree of precision that could potentially be confusing or misleading to investors. However, the magnitude of these amounts may be significant. Non-GAAP Financial Measures and Forward-Looking Statements
