AVISTA HEALTHCARE PARTNERS SIGNS DEFINITIVE AGREEMENT TO ACQUIRE SANOTACT GROUP

Damier Group joins as strategic co-investor alongside existing investor FLOTTE Beteiligungen GmbH ("FLOTTE") to reinvest alongside the new shareholders

NEW YORK, May 22, 2026 /PRNewswire/ -- Avista Healthcare Partners ("Avista"), a leading private equity firm focused exclusively on healthcare, and Damier Group ("Damier") have signed a definitive agreement to acquire sanotact Group GmbH ("sanotact" or the "Company"), an established and innovative German vitamins, minerals, and supplements ("VMS") platform.

Headquartered in Münster, Germany, sanotact specializes in the development, manufacturing, and commercialization of VMS products. The Company operates a diversified business model combining a scaled, full-service CDMO platform with capabilities across all major VMS dosage forms and a portfolio of branded VMS products, including sanotact®, an established German VMS brand. sanotact serves leading drugstore and distribution customers and has established a strong reputation as a trusted innovation partner, underpinned by its high-quality manufacturing and broad product capabilities across 80 international markets.

Thompson Dean, Chairman of Avista, said: "sanotact represents a compelling opportunity to invest in a premier independent VMS platform in Europe. The Company is well-positioned to benefit from strong secular tailwinds, including rising consumer focus on preventative health. sanotact's differentiated capabilities, strong innovation engine, and established market position provide a solid foundation to drive robust growth. We look forward to partnering with management to support sanotact's next phase of development."

Yvan Vindevogel, Founder of Damier Group, added: "sanotact fits squarely within Damier's investment philosophy of backing platforms that anticipate long-term consumer health trends. The shift toward self-care continues to accelerate across Europe, and sanotact's understanding of customer needs positions the company well to capture this growth. Under Martin Spengler's leadership, the team has consistently translated the company's vision into strong financial results, a testament to sanotact's strategy and execution. We are proud to support the company alongside Avista and FLOTTE in this next chapter."

Martin Spengler, Chief Executive Officer of sanotact, added: "We are excited to partner with Avista, Damier and FLOTTE as we continue to build on sanotact's strong momentum. Both Avista and Damier bring deep healthcare expertise, network and a proven track record of supporting growth and strategic expansion, which will enable us to further enhance our innovation capabilities, expand our international footprint, and continue delivering high-quality products to our customers."

Haymo Modelhart, Chairman of FLOTTE, said: "It was extremely important for us to find new partners who shared our long-term vision, as well as our commitment to quality and strong customer relationships that have defined sanotact over the years. We are delighted to partner with Avista and Damier, and believe their experience and strategic perspective make them ideal partners to support the Company's future development."

Avista's depth of experience in consumer healthcare across North America and Europe was instrumental in securing this partnership, marking its ninth platform investment in the sector. Over the last decade, Avista has completed a number of portfolio-enhancing investments in consumer healthcare. The investment also represents a continuation of Avista's partnership with Yvan Vindevogel and his family office, the Damier Group. As part of the transaction, existing shareholder FLOTTE will make a significant reinvestment and continue to support the growth of the company.

The transaction is subject to approval by the relevant regulatory authorities.
