ALSTOM: The Alstom board has appointed Martin Sion as Chief Executive Officer with effect from April 1 2026. He will succeed Henri Poupart-Lafarge, who has been CEO since February 2016 and announced in May that he had decided not to seek a further term.
‘The board has conducted an extensive search process over the last few months, and we believe that Martin Sion has the necessary experience to lead Alstom’, Chairman Philippe Petitcolin said on October 9. ‘We look forward to welcoming him in April 2026. Until then, Henri Poupart-Lafarge will continue in his role, thus ensuring a smooth transition.’
A graduate of the École Centrale de Paris, Sion joined Société Européenne de Propulsion in 1990, where he held various engineering positions. In 2005 he became head of the Technical Department of Snecma’s Space Engines Division, and was subsequently appointed head of the Improvement Strategy Department at Snecma (now Safran Aircraft Engines) and in 2009 head of the Build-up and Equipment Industrial Excellence Centre. From 2010 to 2013 he headed the Space Engines division. He then joined Aircelle (now Safran Nacelles) in 2013 as CEO, and in 2015 was appointed Chairman of Safran Electronics & Defense. He has been a member of ArianeGroup’s board since 2020 and became CEO in 2023.
