First Quarter 2014 – Earnings Call 2

Non-GAAP measures

This presentation includes information regarding certain non-GAAP financial measures, including , Adjusted EBITDA, Adjusted EBITDA per metric ton, Adjusted Free Cash Flow and Net Debt. These measures are presented because management uses this information to monitor and evaluate financial results and trends and believes this information to also be useful for investors. Adjusted EBITDA measures are frequently used by securities analysts, investors and other interested parties in their evaluation of Constellium and in comparison to other companies, many of which present an adjusted EBITDA-related performance measure when reporting their results. Adjusted EBITDA, Adjusted EBITDA per Metric Ton, Adjusted Free Cash Flow and Net Debt are not presentations made in accordance with IFRS and may not be comparable to similarly titled measures of other companies. These non-GAAP financial measures supplement our IFRS disclosures and should not be considered an alternative to the IFRS measures. This presentation provides a reconciliation of non-GAAP financial measures to the most directly comparable GAAP financial measures.
