G Square Acquires Serres to Fuel Sustainable MedTech Expansion

ESPOO, Finland – January 20, 2026 – In a significant move that underscores the growing financial momentum behind sustainable healthcare, European private equity investor G Square has signed an agreement to acquire a majority stake in Serres, a Finnish pioneer in surgical fluid management solutions. The deal is poised to inject substantial capital and strategic expertise into Serres, accelerating its global expansion plans and cementing its position as a leader in environmentally responsible medical technology.

The long-standing family owner, Paree Group, will retain a significant minority stake, transitioning from sole owner to a strategic partner in the company's next evolutionary phase. This hybrid ownership structure is designed to combine the agility and deep industry knowledge of a family-run enterprise with the financial muscle and global network of a seasoned private equity firm. The transaction, expected to close in the first quarter of 2026, marks a pivotal moment for the 50-year-old Finnish company as it sets its sights on major growth, particularly in the competitive United States market.

A Strategic Bet on Green MedTech

G Square's investment is more than a standard acquisition; it's a calculated bet on the future of the MedTech industry, where sustainability is rapidly shifting from a corporate social responsibility talking point to a core market differentiator. Serres has been at the forefront of this trend, embedding circularity and resource efficiency into its product design and operations long before it became a global priority.

"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," stated Nicke Svanvik, CEO of Serres. He noted that the demand for eco-conscious single-use products is accelerating worldwide, a trend that positions Serres for significant growth. "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," Svanvik added.

The partnership aims to leverage this unique selling proposition. G Square, which specializes in high-growth healthcare companies, sees Serres not just as a successful manufacturer but as a platform for building a leading international MedTech entity focused on sustainable solutions for surgery and intensive care.

The Finnish Forerunner's Global Ambition

Founded over five decades ago in Kauhajoki, Finland, Serres has quietly grown into a global powerhouse in its niche. The company’s high-performance suction bags and fluid disposal systems are critical components in over 80,000 surgical procedures every day. Its technology is trusted by a remarkable 50% of the world's top 100 hospitals, a testament to its quality and reliability. With a turnover of EUR 38 million in 2024, the company has built a formidable reputation from its advanced, highly automated production facilities in Kauhajoki and Saarijärvi.

For the founding Jyllilä family and their holding company Paree Group, the decision to bring in an outside partner reflects a strategic recognition of the company's untapped potential. Kimmo Jyllilä, Chair of the Boards of both Paree Group and Serres, described the company as "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," Jyllilä explained. "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."

By retaining a significant stake, the Paree Group ensures continuity and maintains its legacy while embracing a new chapter of aggressive, strategic growth.

Private Equity Power Play for International Scale

The core of the new strategy revolves around leveraging G Square's expertise to scale Serres internationally. While Serres has a strong foothold in Europe, the partnership is explicitly designed to accelerate its presence in the United States and other key global markets. This will involve a multi-pronged approach, including investment in new product development, bolstering commercial capabilities, and pursuing targeted acquisitions to quickly strengthen market reach and build a comprehensive MedTech platform.

"Serres is an outstanding company; a true European champion in its field with world-class sustainable products and a strong culture of innovation," said Oliver Hoenich, Partner at G Square. "The company has built a unique platform with strong potential to grow globally."

Yasemin Arik, another Partner at G Square, echoed this sentiment, emphasizing the collaborative nature of the investment. "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," Arik commented.

This strategy is typical for G Square, which has a track record of identifying innovative European healthcare companies and providing the resources needed for them to compete on a global stage. The focus on both organic growth and strategic M&A indicates a dynamic and ambitious plan for the coming years.

Redefining Workflows in the Modern Operating Room

Beyond the financial and strategic implications, the deal shines a light on the critical role of fluid management in modern healthcare. Surgical fluid management is essential for maintaining a clear and safe operating field, preventing contamination, and ensuring the accurate measurement of fluid loss during procedures. Serres' systems are designed to make this process not only safe and hygienic but also highly efficient and environmentally responsible.

By creating a closed system for fluid collection and disposal, Serres helps hospitals minimize staff exposure to potentially infectious fluids, streamline cleanup processes, and reduce their environmental footprint. The investment from G Square is expected to drive further innovation in this area, potentially leading to wider adoption of these advanced systems and improving standards of care and operational efficiency in hospitals worldwide. The deal sets the stage for a new chapter of growth for the Finnish innovator, driven by a shared vision for a safer and more sustainable global healthcare landscape.
