G Square, a leading European healthcare private equity firm, has signed an agreement to acquire a majority stake in Serres, a global frontrunner in sustainable surgical fluid management solutions. The move aims to accelerate Serres’ global expansion and cement its position as a sustainability leader in MedTech.
The Paree Group, Serres’ long-standing family owner, will retain a significant stake and remain a strategic partner in the company’s next growth phase. Together, G Square and Paree plan to scale Serres internationally, invest in new products, expand commercial capabilities, and pursue targeted acquisitions to strengthen its global footprint. The transaction is expected to close in the first quarter of 2026.
“Serres is one of the Finnish industrial success stories. After decades of continuous development, we see enormous potential ahead requiring greater international reach and resources than we could deploy alone.
"G Square brings deep healthcare expertise, global networks, and the financial strength needed to elevate Serres to the next level. This partnership is a natural and very positive continuation of our long-term commitment to the company,” said Kimmo Jyllilä, Chair of the Boards of Paree Group and Serres.
“Serres is an outstanding company; a true European champion in its field with world-class sustainable products and a strong culture of innovation. The company has built a unique platform with strong potential to grow globally,” said Oliver Hoenich, Partner at G Square.
“We are excited to partner with the Jyllilä family to support Serres and its management team in accelerating growth, widening international reach and strengthening Serres' leading market position in sustainable solutions for surgery and intensive care,” added Yasemin Arik, Partner at G Square.
Founded over 50 years ago, Serres has grown from a family-owned business in Kauhajoki, Finland, into a global leader in surgical fluid management. Its high-performance suction bags and fluid disposal solutions are used in over 80,000 surgical procedures daily and trusted by 50% of the world’s top 100 hospitals.
“Sustainability is not just an add on for us; it is the foundation of our strategy and a major differentiator in the market, embedded across our entire value chain. The demand for sustainable single-use solutions is accelerating globally, and Serres is exceptionally well-positioned to lead this transformation.
"With G Square, we gain the support needed to expand faster and serve more hospitals worldwide with safe, efficient and environmentally responsible fluid management solutions,” said Nicke Svanvik, CEO of Serres.
