This Amendment No. 6 (this "Amendment") is being filed by Bpifrance Participations S.A., a societe anonyme incorporated under the laws of the Republic of France ("Bpifrance Participations"), EPIC Bpifrance, a French public institution of industrial and commercial nature ("EPIC"), Bpifrance S.A., a societe anonyme incorporated under the laws of the Republic of France ("Bpifrance"), and Caisse des depots, a French special public entity (etablissement special) ("CDC") (collectively, the "Reporting Persons") pursuant to Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the "Exchange Act").
This Amendment relates to the Ordinary Shares, nominal value Euro 0.02 per share (the "Ordinary Shares") of Constellium SE (the "Issuer"). This Amendment amends the Statement on Schedule 13D relating to Ordinary Shares of the Issuer filed with the Securities and Exchange Commission (the "SEC") on June 10, 2013, as amended by Amendment No. 1 filed with the SEC on July 25, 2013, Amendment No. 2 filed with the SEC on September 7, 2017, Amendment No. 3 filed with the SEC on November 8, 2017, Amendment No. 4 filed with the SEC on August 10, 2023, and Amendment No. 5 filed with the SEC on June 6, 2024 (as amended, the "Schedule 13D"). Except as specifically provided herein, this Amendment does not modify any of the information previously reported in the Schedule 13D. Capitalized terms used in this Amendment but not otherwise defined herein have the meanings given to them in the Schedule 13D.

**Item 4. Purpose of Transaction**

Item 4 is hereby amended and supplemented as follows:
On May 26, 2026, Bpifrance Participations sold 4,190,000 Ordinary Shares by two block trades each at $33.89 per share.

All of the Ordinary Shares that are held of record by the Reporting Persons as reported herein were acquired for investment purposes.

The Reporting Persons may engage from time to time in ordinary course transactions with financial institutions with respect to the securities described herein.

Except as set forth above, none of the Reporting Persons currently has any plans or proposals which would be related to or would result in any of the matters described in Items 4(a)-(j) of the Instructions to Schedule 13D.

**Item 5. Interest in Securities of the Issuer**

As of the date hereof, none of Bpifrance S.A., CDC, or EPIC holds any Ordinary Shares directly.
