Ravenswood plan termination
During the three months ended September 30, 2026, the Group settled the Constellium Rolled Products Ravenswood
Salaried Pension Plan (the "Plan") through a combination of lump-sum benefit payments and the purchase of an annuity
contract transferring the remaining pension obligations to a third-party financial institution. As a result, the Group derecognized 
$47 million of pension obligations and $44 million of pension assets attributable to the Plan.
