Supported by Amethis and a consortium of investors, EIF Group strengthens its Capex division with the acquisition of ACSIO
Paris, Marseille – January 19th, 2026
Founded in 1958, EIF Group is a leading European player in operational performance consulting, specializing in tax and parafiscal schemes as well as support for innovation and investments financing. With a presence in France and internationally, the Group supports companies, social landlords and local authorities in areas such as local taxation, urban planning, innovation and the financing of energy savings projects.
As part of its development strategy, EIF Group has announced the acquisition of 100% of the share capital of Acsio Conseil and Acsio Énergie (“ACSIO”). ACSIO is an Île-de-France–based firm specializing in advisory services for investment, innovation and energy-saving projects financing, thereby strengthening EIF Group’s positioning in these strategic markets.
This structuring transaction, which expands the Group’s offering in innovation and energy-saving projects financing for industrial and tertiary clients, is part of EIF’s active and targeted external growth strategy deployed since the opening of its capital to Amethis and a pool of leading financial investors alongside management.
Strengthening a Capex division with strong growth potential
Founded and led by Clara and Clément Moreau, ACSIO generates approximately €8 million in revenue and employs a team of 30 professionals. The company has a strong and recognized position in two high value-added segments:
- innovation and investment financing,
- promoting energy savings, particularly through C2E schemes.
ACSIO’s founders are reinvesting alongside EIF’s management to support the Group’s development project, illustrating a strong alignment of strategic vision.
A platform gaining strong momentum
Following an initial capital transaction last June marked by the entry of Amethis, Société Générale Capital Partenaires, Idia Capital Investissement, Socadif and Rives Croissance, EIF has embarked on an active market consolidation trajectory. The acquisition of SBEP in September, followed by that of ACSIO in December 2025, illustrates the Group’s ability to rapidly execute a disciplined build-up strategy.
A clear ambition to create value in the medium-term
“ ACSIO was among the priority targets of our external growth strategy. This transaction allows us to significantly strengthen our expertise in innovation financing and C2E schemes, two key areas of expertise for our industrial and tertiary clients, ” said Christophe Thévenot, Chairman of EIF Group. He added: “The integration of ACSIO is fully aligned with our ambition to balance our Capex and tax divisions by 2027.”
“ The acquisition of ACSIO perfectly illustrates the strategy we are supporting at EIF: building, through targeted external growth, a leading platform focused on high value-added expertise and strong structural growth drivers. The combination of EIF and ACSIO is based on clear industrial complementarity, committed teams and a shared ambition to create sustainable value for clients ” said Romain Gauvrit and Nicolas Manardo, Senior Partners at Amethis.
EIF was advised by Linkers on this transaction, while the sellers were advised by Financière de Courcelles.
