Cautionary Note Regarding Forward-Looking Statements

Information provided and statements contained in this Current Report on Form 8-K or the Exhibits hereto are not purely historical are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (“Securities Act”), Section 21E of the Securities Exchange Act of 1934, as amended (“Exchange Act”), and the Private Securities Litigation Reform Act of 1995. Such forward-looking statements only speak as of the date of this release and the Company assumes no obligation to update the information included in this release. Such forward-looking statements include information concerning our possible or assumed future results of operations, including descriptions of our business strategy, and the cost savings and other benefits that we expect to achieve from our restructuring. These statements often include words such as “believe,” “expect,” “anticipate,” “intend,” “predict,” “plan,” "should," or similar expressions. These statements are not guarantees of performance or results, and they involve risks, uncertainties, and assumptions. Although we believe that these forward-looking statements are based on reasonable assumptions, there are many factors that could affect our actual financial results or results of operations and could cause actual results to differ materially from those in the forward-looking statements. These factors include or relate to: our ability to obtain sufficient acceptances in connection with our solicitation of debt holder support; our ability to obtain the bankruptcy court’s approval with respect to motions or other requests made in any necessary chapter 11 case, including maintaining strategic control as debtor-in-possession; our ability to confirm and consummate a chapter 11 plan of reorganization in any necessary chapter 11 case; the effects of the filing of any necessary chapter 11 case on our business and the interests of various constituents; the bankruptcy court’s rulings in any necessary chapter 11 case, as well as the outcome of any such case in general; the length of time that we may operate under any necessary chapter 11 protection and the continued availability of operating capital during the pendency of any necessary chapter 11 case; risks associated with third party motions or objections in any necessary chapter 11 case, which may interfere with our ability to confirm and consummate a chapter 11 plan of reorganization; the potential adverse effects of any necessary chapter 11 case on our liquidity or results of operations; our ability to execute the Company’s business and financial reorganization plan; and increased advisory costs to execute our restructuring. Other factors include our ability to effectively manage our operational initiatives and restructuring activities, the impact of volatility of metals prices, the cyclical and seasonal aspects of our business, our ability to effectively manage inventory levels, our ability to successfully complete the remaining steps in our strategic refinancing process, and the impact of our substantial level of indebtedness, as well as including those risk factors identified in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, our Current Report on Form 8-K filed April 7, 2017, and our Quarterly Report on Form 10-Q for the first quarter ended March 31, 2017, which we will file shortly. All future written and oral forward-looking statements by us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to above. Except as required by the federal securities laws, we do not have any obligations or intention to release publicly any revisions to any forward-looking statements to reflect events or circumstances in the future, to reflect the occurrence of unanticipated events or for any other reason.
