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 October 8, 2025, to

separate the roles of Chairman and CEO of ALTEN. The Board has therefore decided, following the

recommendation of the Remuneration and Nomination Committee, to appoint Mr Cyril Malargé as Chief

Executive Officer. These decisions will be effective no later than January 31, 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 strenghtened 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 Group 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 French

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 the position

of Group CEO to Cyril Malargé. He 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 of Mr Simon Azoulay and Mr Cyril Malargé by the

Board of Directors, as Chairman of the Board and Chief Executive Officer of ALTEN, respectively.
