Investor Presentation November 2016 Exhibit 99.1

Forward-Looking Statements This presentation contains forward-looking statements. These statements can be identified by the use of forward-looking terminology including “will,” “may,” “believe,” “expect,” “anticipate,” “estimate,” “continue,” or other similar words. These statements discuss future expectations including company growth expectations, demand for our products, capacity expansion plans, market trends, liquidity, transportation services, commercial product launches and research and development plans and may contain projections of financial condition or of results of operations, or state other “forward-looking” information. These forward-looking statements involve risks and uncertainties. Many of these risks are beyond management’s control. When considering these forward-looking statements, you should keep in mind the risk factors, Management’s Discussion and Analysis of Financial Condition and Results of Operations, and other cautionary statements in the company’s SEC filings. Forward-looking statements are not guarantees of future performance or an assurance that our current assumptions or projections are valid. Our actual results and plans could differ materially from those expressed in any forward-looking statements. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information or future events, except as required by law. This presentation includes certain non-GAAP financial measures, including EBITDA and Adjusted EBITDA. These non-GAAP financial measures are used as supplemental financial measures by our management to evaluate our operating performance and compare the results of our operations from period to period without regard to the impact of our financing methods, capital structure or non-operating income and expenses. Adjusted EBITDA is also used by our lenders to evaluate our compliance with covenants. We believe that these measures are meaningful to our investors to enhance their understanding of our financial performance. These measures should be considered supplemental to and not a substitute for financial information prepared in accordance with GAAP and may differ from similarly titled measures used by other companies. For a reconciliation of such measures to the most directly comparable GAAP term, please see slide 24 of this presentation.
