This update does not reflect any new share purchases or sales, but rather a clarification of prior disclosures.

CONSTELLIUM SE filed an amended Form 3 for President, AS&I Stephane Corre to update his reported holdings. As of January 1, 2026, he beneficially owns 64,694 ordinary shares in total.
This amount consists of 50,644 ordinary shares held directly and 14,050 restricted stock units that remain subject to vesting restrictions. The amendment explains these RSUs were inadvertently omitted from Corre’s original Form 3 and from two Form 4 filings submitted before this amendment, so the change reflects a correction to previously reported ownership rather than a new transaction.
