1. Separation of the roles of Chairman and Chief Executive Officer

Simon Azoulay, Chairman and CEO, and the Board of Directors of ALTEN are pleased to announce that, in
accordance with Mr. Simon Azoulay’s wishes, the Board of Directors has decided on 8 October 2025 to separate
the roles of Chairman and Chief Executive Officer of ALTEN. The Board has therefore decided following the

Executive Officer. These decisions will be effective no later than 31 January 2026, after Mr. Cyril Malargé has
been released from his current duties.
This major step will enable the ALTEN group to continue its development strategy with strengthened
governance. Mr. Simon Azoulay will continue to serve as Chairman of the Board of Directors of ALTEN and will
support Mr. Cyril Malargé in his transition to the role.
Cyril Malargé, 52, has served as Chief Executive Officer of Sopra Steria since 2022, where he has spent most of
his career. A graduate of the Ecole Spéciale de Mécanique et d’Electricité (ESME) and holding a PhD in Electrical
Engineering, Cyril Malargé began his career at Bel Groupe before becoming CIO of Lafont. He joined Sopra
Steria in 2002 as Director of Major Industrial Accounts Projects. In 2008, he was appointed Director of the
France Industry & Services Business Unit. In 2015, he joined the Sopra Steria Executive Committee as Executive
Director in charge of Consulting, Systems Integration, and Infrastructure Management. From 2020 to 2022, he
served as Chief Operating Officer (COO) of the Sopra Steria Group.
Mr. Simon Azoulay stated: "After more than 35 years leading ALTEN, I am very pleased to hand over to Cyril
Malargé the position of Group CEO. Cyril Malargé has the skills and experience necessary to ensure the
continued development of the ALTEN group. I look forward to supporting him in this managerial transition."
Mr. Cyril Malargé stated: "I am very happy to join the ALTEN group, a wonderful engineering company founded
on entrepreneurial spirit. I sincerely thank Simon Azoulay for his trust, and I look forward to working with him,
the Board of Directors, and the entire ALTEN team on the development and future of the Group."
A new press release will confirm the effective appointments by the Board of Directors of Mr. Simon Azoulay
and Mr. Cyril Malargé, respectively as Chairman of the Board and Chief Executive Officer of ALTEN.
