CAPZA and Myrium, a leading independent operator dedicated to sustainable building performance, announce that they have entered into exclusive negotiations to initiate a strategic collaboration and support the Group in this new phase of development. Bpifrance, a minority shareholder of Myrium, is reinvesting as part of this transaction, reaffirming its commitment that has spanned more than a decade.

As part of this new chapter, CAPZA will become the Myrium’s new long-term financial partner and will acquire a majority stake in the share capital, alongside management and the employee shareholding fund (FCPE), which together will retain nearly 40% of the capital. This new partnership strengthens the collective entrepreneurial model at the heart of Myrium’s identity, ensures the Group’s strategic continuity, and supports its development in pursuit of an ambitious goal: to build an independent, innovative, and committed national operator serving sustainable buildings.

Founded in 1923 and based in Vélizy-Villacoublay, Myrium offers its clients a comprehensive multi-technical service portfolio for their buildings: HVAC engineering, electrical engineering, plumbing, roofing, waterproofing, energy performance, architectural fit-out, full-scope renovation works, and greening solutions. The Group operates across the entire lifecycle of existing buildings, from renovation to maintenance, in a context of increasing resource preservation requirements. With the expertise of more than 1,600 employees, Myrium serves a broad B2B customer base: private and public tertiary sectors, industry, infrastructure, social housing, and condominiums, primarily in the Île-de-France region and now in Western France following the acquisition of Eddia.

Myrium’s focuses its development both on steady organic growth, driven by customer satisfaction and on external growth with 24 successful acquisitions since 2015, leveraging its expertise in welcoming and empowering new companies. The Group aims to accelerate its development by continuing a targeted acquisition policy that creates value, both in Île-de-France and in regional markets, notably by federating recognised local platforms in major French metropolitan areas. The objective is to build a broader network while preserving the entrepreneurial DNA of simplicity, responsibility, and proximity that defines Myrium’s strength.

Through this equity transaction, CAPZA will acquire a majority stake in Myrium via its Flex Equity Mid-Market II fund, marking its seventh transaction since May 2022. Amundi Private Equity Funds will join CAPZA as a minority investor. Management and the employee shareholding fund will reinvest significantly, collectively representing 40% of the new shareholding structure. Myrium’s historical shareholders, the Rougnon family and Bpifrance, will continue to support the company in this new stage, while Groupe Chevrillon, which entered the capital in 2022, will exit its stake.

Completion of the transaction is subject to customary closing conditions and approvals.

Frédéric Viet, President of Myrium, comments: “In recent years, Myrium has built a leading independent position in Île-de-France, founded on strong values of technical expertise, proximity, service quality, and responsibility that unite our teams. This impressively solid foundation enables us to approach this new chapter of our development with confidence and broader ambition. We are delighted with the partnership established with CAPZA, which shares our vision and has the strength to support us, relying on the commitment of our managers and executives to the project and jointly sustaining our collective entrepreneurial model.”

Antoine Druais and Thibault Chatagnon, Partners at CAPZA, comment: “We are delighted to support Frédéric Viet, the Executive Committee, and all Myrium teams in this new growth cycle. Myrium’s entrepreneurial DNA, its ability to combine decentralisation with execution discipline, and its strong ESG culture are the foundations of a model that has proven its relevance to clients, teams, and partner companies. Building on these fundamentals, Myrium will continue to grow beyond Île-de-France in its core businesses and expand into adjacent sectors.”

François de Guitaut, Partner in charge of investments at Groupe Chevrillon, adds: “Supporting a company like Myrium in its development has been a pleasure every step of the way. A united, high-quality team rallied around a common project. We wish Myrium and its shareholders every success in the years ahead.”
