On April 23, 2026, Millennium Management LLC, Millennium Group Management LLC, and Israel A. Englander filed a Schedule 13G/A regarding their holdings in Constellium SE (CSTM). The filing indicates that as of March 31, 2026, the reporting persons beneficially own 3,470,091 ordinary shares, representing approximately 2.5% of the class. This reflects a significant decrease from their previously reported position of 6,269,869 shares. The reported securities are held by entities subject to voting control and investment discretion by Millennium Management LLC, Millennium Group Management LLC (the managing member of Millennium Management LLC), and Mr. Englander (the sole voting trustee of the managing member of Millennium Group Management LLC). As the combined ownership has fallen below the 5% threshold, the filers have indicated that they no longer hold a reportable stake exceeding 5% of the company's ordinary shares. The filing was made under Rule 13d-1(c) and includes a joint filing agreement between the three reporting entities.
