About This Fund
Mérieux Participations 4 (MP4) is the fourth growth buyout fund managed by Mérieux Equity Partners (MxEP), a leading European private equity firm dedicated exclusively to the healthcare and nutrition sectors. Headquartered in Lyon and Paris, France, Mérieux Equity Partners manages approximately €1.6 billion in assets under management across its buyout and venture platforms. MP4 was launched in May 2021 with an initial target of €500 million and closed above target in September 2023 at approximately €568 million, making it one of the largest dedicated healthcare buyout vehicles in Europe.
The fund pursues a growth buyout strategy, acquiring majority and significant minority stakes in profitable, fast-growing companies operating in the health and nutrition sectors across Europe. MP4 targets companies with proven business models, strong market positions in niche segments, and ambitious organic and inorganic growth plans. The fund's mandate covers the full spectrum of healthcare — including medtech, diagnostics, contract research and manufacturing organizations (CROs/CMOs), digital health, and specialty nutrition — with a preference for businesses with pan-European or global growth potential. Mérieux Equity Partners brings deep sector expertise, a global industrial network through its parent Institut Mérieux, and a track record of active portfolio management.
By final close, Mérieux Participations 4 had already deployed capital across more than eleven healthcare investments, demonstrating strong momentum consistent with the firm's thesis of backing high-growth European healthcare champions. The fund reserved for professional clients under AMF regulation and is part of a broader franchise that includes Mérieux Participations 1 through 3, which collectively established a strong track record of value creation across the European healthcare ecosystem. Portfolio companies include InnoSyn B.V. (Netherlands, outsourced process R&D) and Health in Code (Spain, integrated clinical genetics platform, via Alantra Healthcare continuation fund).
