The Board looks forward to supporting her in this next phase of Constellium's journey.

On behalf of the Board, I would like to sincerely thank Jean-Marc for his outstanding leadership and dedication over nearly a decade. Under his tenure, Constellium built a strong executive team, considerably reinforced its market and financial position, and delivered significant value to shareholders. He was instrumental in navigating many challenges, and under his direction, Constellium built the resilience and strengths needed to face future uncertainties and seize new opportunities."

Jean-Marc Germain commented: "It has been an extraordinary honor to lead Constellium, to have the steadfast support of a strong management team and of the Board, and to collaborate with such talented colleagues around the world. Together, we have built a stronger company, and I am deeply proud of what we have accomplished. Ingrid is an exceptional leader with the vision and experience to guide Constellium forward, and I am confident she will take the company to even greater heights."

"I am honored by the trust placed in me by the Board," said Ingrid Joerg. "Over the past years, we have built and executed a strong growth strategy for Constellium, which I am committed to carry forward. Together, with the support of our talented teams, we will continue to strengthen our partnerships with our customers, deliver innovative, sustainable solutions and create value for shareholders."
