RSM, the 6th largest global network of advisory and audit services, conducted the buy-side financial and tax due diligence for Astek, a global player in engineering and technology consulting, during its acquisition of Elysis, a French consulting firm specializing in project management and control.


A multidisciplinary team, composed of RSM partners Eric Fougedoire and Cécile Guyot and their teams, supported Astek during this external growth transaction.

With the acquisitions of Business and Engineering Solution (B.E.S, Belgique) in 2023, Conmore (Suède) in 2022 et Immune-IT (Pays-Bas) in 2021, this marks the fourth transaction the team has been involved in.

The Corporate Finance division further strengthens its role as a key partner for international groups in their targeted acquisition strategy in Europe.

Official press release from Astek

Astek announces the acquisition of the French company Elysis, a recognized consulting firm specializing in project management and control. This acquisition enables Astek to enrich its project engineering offering.

With the integration of Elysis, Astek strengthens its presence in France and its ability to meet the project management needs of its clients across all sectors, including large industrial projects.

Founded in 2011, Elysis has 200 employees across 6 offices in France and Belgium, with a turnover of €17.6 million. The company initially built its reputation in the automotive and rail industries, particularly in the Hauts-de-France region, thanks to its mastery of economic and technological challenges. This solid foundation has allowed it to diversify into other sectors. Today, Elysis also operates in various fields such as energy, aerospace, healthcare, infrastructure, and retail.

Elysis excels in managing and leading engineering activities, offering operational support in product, process, and infrastructure engineering. This expertise is complemented by control over quality, cost, and time components, essential for optimizing project profitability. Finally, Elysis strengthens Astek's capabilities in project and program management, particularly through Cost & Risk Management, PMO, and project reporting services.

This transaction allows Astek to strengthen its positioning and become a major player in project management in France by combining the offerings of Emisys and Elysis.

Julien Gavaldon, Chairman of the Executive Board of the Astek Group, stated: 

"This strategic acquisition strengthens our positioning in several key areas of project management and allows us to undertake more complex and diverse projects. Elysis brings complementary skills to those of Emisys, which was integrated into the Group in 2022. Our ability to offer a full range of project engineering services to our clients is thus enhanced. We are excited to integrate the talents of Elysis, whose expertise will be a major asset for our operations."

Jérémy Gonce, CEO and Founder of Elysis, who will remain in charge of the company, added : 

"Joining the Astek Group represents a great opportunity for Elysis to continue its expansion and offer new prospects to our clients and employees. We look forward to contributing to Astek's growth dynamic and participating in its ambition to become a global leader in technology and engineering consulting."

Astek continues to pursue its strategy of targeted acquisitions and double-digit organic growth. This new acquisition confirms Astek's commitment to developing strong synergies within its Group to provide increasingly innovative solutions to its clients.
