Constellium names new chief executive
Written by Stephanie Ritenbaugh
Constellium SE announced Chief Operating Officer Ingrid Joerg will succeed Jean-Marc Germain as CEO and join the board of directors, effective Jan. 1.
The transition comes as a part of multi-year leadership succession planning. Germain, who is retiring in December, is expected to serve as special adviser to the company’s board and management in the new year.
“Ingrid is the ideal choice to lead Constellium’s development,” said Jean-Christophe Deslarzes, chairman of the board. “With more than 25 years of experience in the aluminum industry, including 10 years with Constellium, Ingrid combines deep industry expertise, proven operational excellence, and a strong commitment to our customers, employees, and shareholders.”
Joerg joined Paris-based Constellium in 2015 as president of its aerospace and transportation business unit before being appointed chief operating officer in 2023. Previously, she was CEO of Aleris Rolled Products Europe. Joerg also held leadership positions with Alcoa as president of its European and Latin American Mill Products business unit, and in commercial positions with Amag Austria.
Deslarzes noted that, under Germain’s tenure, “Constellium built a strong executive team, considerably reinforced its market and financial position, and delivered significant value to shareholders.”
Germain has served as an executive director and CEO since 2016. Previously, Germain was CEO of Algeco Scotsman, a Baltimore-based global business services provider focused on modular space and secure portable storages. Previously, Germain held several leadership positions in the aluminum industry, including senior executive roles in operations, sales and marketing, financial planning and strategy with Pechiney, Alcan, and Novelis. His last position was with Novelis from 2008 to 2012 as president for North American operations.
