Third Quarter 2020 Earnings Call October 27, 2020 Exhibit 99.2

Forward-looking statements Certain statements contained in this press release may constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. This press release may contain “forward-looking statements” with respect to our business, results of operations and financial condition, and our expectations or beliefs concerning future events and conditions. You can identify forward-looking statements because they contain words such as, but not limited to, “believes,” “expects,” “may,” “should,” “approximately,” “anticipates,” “estimates,” “intends,” “plans,” “targets,” likely,” “will,” “would,” “could” and similar expressions (or the negative of these terminologies or expressions). All forward-looking statements involve risks and uncertainties. Many risks and uncertainties are inherent in our industry and markets, while others are more specific to our business and operations. These risks and uncertainties include, but are not limited to: market competition; economic downturn; disruption to business operations, including the length and magnitude of disruption resulting from the global COVID-19 pandemic; the inability to meet customer demand and quality requirements; the loss of key customers, suppliers or other business relationships; the capacity and effectiveness of our hedging policy activities; the loss of key employees; levels of indebtedness which could limit our operating flexibility and opportunities; and other risk factors set forth under the heading “Risk Factors” in our Annual Report on Form 20-F, and as described from time to time in subsequent reports filed with the U.S. Securities and Exchange Commission. The occurrence of the events described and the achievement of the expected results depend on many events, some or all of which are not predictable or within our control. Consequently, actual results may differ materially from the forward-looking statements contained in this press release. We undertake no obligation to update or revise any forward-looking statement as a result of new information, future events or otherwise, except as required by law.

Non-GAAP measures This presentation includes information regarding certain non-GAAP financial measures, including Adjusted EBITDA, Adjusted EBITDA per metric ton, 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, 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. We are not able to provide a reconciliation of Adjusted EBITDA guidance to net income, the comparable GAAP measure, because certain items that are excluded from Adjusted EBITDA cannot be reasonably predicted or are not in our control. In particular, we are unable to forecast the timing or magnitude of realized and unrealized gains and losses on derivative instruments, metal lag, impairment or restructuring charges, or taxes without unreasonable efforts, and these items could significantly impact, either individually or in the aggregate, our net income in the future.
