Item 5.07

Submissions of Matters to a Vote of Security Holders

Constellium SE (the “Company”) held its Annual General Meeting of Shareholders on May 21, 2026. The proposals

for the appointment of Ingrid Joerg and the re-appointment of John Ormerod to the Company’s Board of Directors

for a period of three years following the Annual General Meeting, passed.

The Company’s shareholders approved, on an advisory basis, “one year” as the frequency for holding an advisory

(non-binding) vote on the compensation of the Company’s named executive officers. In light of such vote, the

Company has determined to hold the advisory (non-binding) vote on the compensation of the Company’s named

executive officers every year. The results for the remainder of the proposals are as set forth below.

* For the purposes of French law, broker non-votes are treated as abstentions. Therefore, in terms of the voting

results, broker non-votes, like other abstentions, were not counted as a vote cast on the applicable proposal.

The voting results are as follows:
