The Riverside Company, a global investment firm focused on the smaller end of the middle market, has signed a definitive agreement through its European fund to invest in Conformat.
Conformat is a French distributor of consumables and equipment for cleanrooms and controlled environments.
The investment is the fifth add-on to Riverside’s portfolio company, the Dastex Group (Dastex), a pan-European expert in cleanroom contamination control, which Riverside backed in May 2023.
Conformat, founded 40 years ago and headquartered in Rueil-Malmaison, west of Paris, is the market-leading distributor of cleanroom consumables in France – the second largest market in Europe.

The company predominantly serves clients in the life sciences industry, as well as in microelectronics, spatial, and other end-markets.
Conformat offers a wide range of third-party consumables as well as proprietary products developed and sold under its own brands, including wipes, gloves, packaging, and disinfectants. Conformat is also active in the Czech Republic through its own subsidiary.
The company has a strong social responsibility ethos and a formalised ethics and environment charter, meeting Riverside’s desire to invest in socially responsible firms.
Karsten Langer, Riverside Europe Managing Partner, said: “This latest investment is yet another example of Riverside’s commitment to driving ambitious growth transformation projects by identifying attractive add-on acquisitions and intelligent implementation of our well-honed buy-and-build programme. Conformat also shows Riverside’s capabilities to originate off-market opportunities and successfully transact in the French market.”

Laurent Galibert, General Manager of Conformat, said: “The Conformat team is thrilled to bring their knowledge, experience and creativity to the other entities of the Dastex Group and contribute to shape this new European champion.”
Riverside acquired Dastex, a specialised distributor of cleanroom garments and consumables in Europe, in mid-2023, simultaneously completing its first add-on, Vita Verita, in Sweden.
Continuing its buy-and-build strategy, the company added AET, a leading independent player in Norway, in April 2024, and CRTM, another German distributor, in December 2024.

Earlier in 2025, Dastex closed the acquisition of pure11, a leading distributor of cleanroom consumables in the DACH region.
Dastex serves the resilient and growing cleanroom industry, helping customers in pharmaceuticals, life sciences, semiconductors and other high-tech industries to meet ever stricter quality and regulatory standards.
Working with Gaudin on the transaction were Riverside Europe team members Vice President Maxime Meulemeester, Senior Associate Sebastiaan Pauwels and Senior Legal Counsel Peter Parmentier. The investment was sourced by Damien Gaudin.
