office and headquarters to Paris, France (the &#147;Transfer&#148;). Following the approval of Constellium SE&#146;s shareholders on November&nbsp;25, 2019 (&#147;EGM Approval&#148;), the Transfer became effective on December&nbsp;12, 2019 upon the
effectiveness of the registration of Constellium SE with the French Commercial Court and pursuant to French law (the &#147;French Registration&#148;). Following the EGM approval, Constellium SE also executed a deed of amendment amending its articles
of association to conform with French law (as so amended, the &#147;Articles of Association&#148;), which also became effective on December&nbsp;12, 2019, upon the French Registration. Constellium SE expressly adopts the Registration Statement, as
