Forward-Looking Statements Certain statements contained in this presentation may constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. This presentation 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 or industry specific conditions including the impacts of tax and tariff programs, inflation, foreign currency exchange, and industry consolidation; disruption to business operations; natural disasters including severe flooding and other weather-related events; the conflict between Russia and Ukraine and other geopolitical tensions; the inability to meet customer demand and quality requirements; the loss of key customers, suppliers or other business relationships; supply disruptions; excessive inflation; 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 10-K, 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. Third Quarter 2025 - Earnings Call - 2
Non-GAAP Measures This presentation includes information regarding certain non-GAAP financial measures, including Adjusted EBITDA, 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, Free Cash Flow and Net debt are not presentations made in accordance with U.S. GAAP and may not be comparable to similarly titled measures of other companies. These non-GAAP financial measures supplement our GAAP disclosures and should not be considered an alternative to the GAAP measures. This presentation provides a reconciliation of non-GAAP financial measures to the most directly comparable GAAP financial measures. For the definitions or Adjusted EBITDA, Free Cash Flow and Net debt, please refer to our accompanying press release. 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, non-cash impact of metal price 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.

Appendix
Revision of Certain Disclosures in Previously Issued Financial Statements Third Quarter 2025 - Earnings Call - 18 During the third quarter of 2025, the Group identified and corrected certain immaterial errors affecting metal price lag and the resulting Segment Adjusted EBITDA for the A&T segment for certain prior periods in 2025 and 2024. The errors resulted from misclassification of certain items within Cost of sales, which did not impact either the overall Cost of sales or the Group’s consolidated income statements but did impact the non-cash metal price lag and the resulting Segment Adjusted EBITDA for the A&T segment. The Group assessed the materiality of these errors on a quantitative and qualitative basis and concluded that the corrections were not material to any previously issued interim or annual consolidated financial statements. Accordingly, the affected prior period amounts presented in this filing, or that will be presented in prospective filings, have been revised. The impact of these revisions is presented below: Three months ended June 30, 2024 Three months ended September 30, 2024 (in millions of U.S. dollars) As published Adjustment Revised Before adjustment Adjustment Revised A&T 90 4 94 53 1 54 P&ARP 66 66 72 72 AS&I 30 30 7 7 H&C (6) (6) (2) (2) Segment Adjusted EBITDA 180 4 184 130 1 131 Metal price lag 45 (4) 41 (4) (1) (5) Three months ended December 31, 2024 Year ended December 31, 2024 (in millions of U.S. dollars) Before adjustment Adjustment Revised As published Adjustment Revised A&T 56 2 58 285 7 292 P&ARP 56 56 242 242 AS&I 4 4 74 74 H&C (18) (18) (33) (33) Segment Adjusted EBITDA 98 2 100 568 7 575 Metal price lag 27 (2) 25 55 (7) 48 Three months ended March 31, 2025 Three months ended June 30, 2025 (in millions of U.S. dollars) As published Adjustment Revised As published Adjustment Revised A&T 75 7 82 78 6 84 P&ARP 60 60 74 74 AS&I 16 16 18 18 H&C (11) (11) (12) (12) Segment Adjusted EBITDA 140 7 147 159 6 165 Metal price lag 46 (7) 39 (13) (6) (19)
