G Square acquires Serres to boost sustainability leadership, announcing that the European healthcare private equity investor has signed an agreement to purchase a majority stake in Serres, a globally recognised leader in sustainable surgical fluid management solutions, with the aim of expanding its international presence and strengthening its role in environmentally responsible medical technology.

The transaction expected to close in the first quarter of 2026 brings together G Square’s deep healthcare expertise and global network with Serres’ decades-long legacy of innovation and sustainable product design, positioning the company for accelerated growth across Europe, the United States and other key markets worldwide.

A Strategic Partnership Rooted in Shared Values

At the heart of the transaction is a shared vision for sustainable growth in healthcare. Under the terms of the agreement, Serres’ long-standing family owner, Paree Group, will retain a significant minority stake in the company and remain actively involved as a strategic partner. This continuity ensures that Serres’ culture, values, and long-term commitment to sustainability remain intact as the business enters its next phase of expansion.

G Square’s investment model emphasizes long-term value creation through operational excellence, internationalization, and responsible growth—principles that align closely with Serres’ mission. By combining capital investment with strategic guidance and access to a global healthcare network, G Square aims to help Serres scale its impact without compromising product quality or environmental responsibility.

Both organizations have emphasized that the partnership is not about short-term financial optimization, but about building a durable, innovation-led MedTech platform that can serve hospitals worldwide while addressing the healthcare sector’s growing sustainability challenges.

Serres: A Global Leader in Surgical Fluid Management

Founded more than 50 years ago in Kauhajoki, Finland, Serres has established itself as a global leader in surgical suction bags and fluid disposal solutions. The company’s products are used in over 80,000 surgical procedures every day and are trusted by approximately half of the world’s Top 100 hospitals, underscoring its reputation for reliability, performance, and safety.

Serres’ solutions are designed to support a wide range of clinical environments, including operating rooms, intensive care units, and emergency departments. By focusing on efficiency, infection control, and ease of use, the company has become a preferred partner for healthcare providers seeking high-performance fluid management systems.

Equally important is Serres’ strong manufacturing foundation. Its advanced production facilities in Kauhajoki and Saarijärvi are highly automated, optimized for efficiency, and designed to meet stringent quality and regulatory standards. These facilities provide the scalability required to support global growth while maintaining consistent product quality.

Sustainability as a Core Competitive Advantage

Sustainability is not a recent initiative at Serres—it is deeply embedded in the company’s DNA. For decades, Serres has prioritized circularity, material efficiency, and reduced environmental impact in its product design and manufacturing processes. Its surgical fluid management solutions are engineered to minimize waste, lower emissions, and improve disposal efficiency compared to traditional alternatives.

This sustainability-first approach has become an increasingly powerful differentiator as hospitals and healthcare systems face mounting pressure to reduce their environmental footprint. Healthcare is one of the most resource-intensive sectors globally, and single-use medical products, in particular, have come under scrutiny for their environmental impact.

Serres’ leadership has consistently emphasized that sustainability and clinical performance are not mutually exclusive. Instead, the company’s products demonstrate that environmentally responsible design can enhance safety, efficiency, and cost-effectiveness—benefits that resonate strongly with healthcare providers navigating both operational and regulatory challenges.

G Square’s Role in Accelerating Sustainable Growth

G Square brings to the partnership a strong track record of investing in healthcare companies with global growth potential. With deep sector knowledge and a broad international network, the firm is well positioned to support Serres’ expansion into new markets and customer segments.

According to G Square partners, the acquisition reflects a conviction that sustainability will increasingly define competitive advantage in MedTech. By backing Serres, G Square aims to scale a business that already demonstrates how environmental responsibility can be integrated into core operations and product strategy.

The investment will support initiatives such as:

• Expanding Serres’ commercial presence in North America and other key international markets

• Investing in research and development to bring new sustainable products to market

• Strengthening sales, marketing, and distribution capabilities

• Pursuing selective acquisitions that complement Serres’ product portfolio and geographic reach

These efforts are designed to transform Serres from a highly respected specialist into a globally recognized MedTech platform with broad reach and influence.

Responding to Global Demand for Sustainable Medical Solutions

Demand for sustainable healthcare solutions is rising rapidly as hospitals, governments, and regulators set ambitious environmental targets. Many healthcare providers are now evaluating suppliers not only on price and performance, but also on environmental impact, lifecycle emissions, and waste reduction capabilities.

Serres is well positioned to benefit from this shift. Its product portfolio aligns closely with the sustainability objectives of modern healthcare systems, offering solutions that reduce plastic waste, improve disposal efficiency, and support circular economy principles.

With G Square’s backing, Serres plans to accelerate its ability to serve hospitals worldwide that are actively seeking partners capable of helping them meet environmental, social, and governance (ESG) goals without compromising patient safety or clinical outcomes.

Strengthening Innovation and Product Development

Innovation will remain a central pillar of Serres’ growth strategy. The company plans to invest further in product development to enhance performance, usability, and environmental impact across its surgical fluid management solutions.

This includes exploring new materials, refining manufacturing processes, and developing next-generation products that address evolving clinical and sustainability requirements. By leveraging G Square’s experience in scaling innovation-driven healthcare businesses, Serres aims to shorten development cycles and bring new solutions to market more efficiently.

The partnership also creates opportunities to expand Serres’ offerings beyond its core product lines, potentially addressing adjacent areas within surgical and critical care environments where sustainability-focused innovation can deliver meaningful value.

Implications for the Broader MedTech Industry

The acquisition highlights a broader shift within the MedTech and healthcare investment landscape. Sustainability is no longer viewed as a secondary consideration or marketing feature; it is becoming a central driver of strategic decision-making, product development, and capital allocation.

Investors like G Square are increasingly targeting companies that embed environmental responsibility into their operating models, recognizing that such businesses are better positioned for long-term success in a regulated, resource-constrained world.

For the MedTech industry as a whole, the Serres transaction underscores the growing importance of sustainable innovation as hospitals seek suppliers that can support both clinical excellence and environmental stewardship.

Maintaining Continuity While Scaling Globally

One of the defining features of the deal is its emphasis on continuity. By retaining Paree Group as a significant shareholder and strategic partner, Serres ensures that its heritage, culture, and long-term perspective remain intact as it scales.

This continuity is expected to resonate positively with employees, customers, and partners, reinforcing trust during a period of growth and change. It also supports a collaborative governance model that balances entrepreneurial agility with institutional expertise.

G Square has emphasized that preserving what makes Serres unique—its people, values, and sustainability focus—is essential to unlocking the company’s full potential on the global stage.

Expanding International Reach and Market Presence

Geographic expansion is a key priority following the acquisition. While Serres already has a strong presence in Europe and established relationships with leading hospitals worldwide, the partnership with G Square is expected to accelerate growth in the United States and other high-potential markets.

By strengthening local commercial teams, expanding distribution partnerships, and increasing brand visibility, Serres aims to deepen its penetration in markets where demand for sustainable medical solutions is rising rapidly.

This international expansion will be supported by investments in regulatory expertise, supply chain resilience, and customer support infrastructure, ensuring that Serres can deliver consistent quality and service across regions.

A Platform for Long-Term Impact

Beyond financial growth, the partnership between G Square and Serres is positioned as a platform for long-term impact in healthcare. By scaling sustainable surgical solutions globally, the company has the potential to significantly reduce the environmental footprint of surgical procedures worldwide.

This impact-driven approach aligns with broader healthcare goals of improving patient outcomes, enhancing operational efficiency, and reducing environmental harm. It also reinforces the idea that sustainability and profitability can be mutually reinforcing when embedded thoughtfully into business strategy.

Looking Ahead: The Future of Serres Under G Square Ownership

As the transaction moves toward completion, Serres enters a new chapter defined by ambition, investment, and global opportunity. With G Square’s support, the company is poised to accelerate innovation, expand internationally, and strengthen its role as a sustainability leader in MedTech.

The partnership reflects a shared belief that the future of healthcare depends on solutions that balance clinical excellence with environmental responsibility. By scaling a business that already exemplifies this balance, G Square and Serres are setting a benchmark for how sustainable innovation can drive growth, resilience, and long-term value in the global healthcare ecosystem.

In an industry facing mounting pressure to deliver better outcomes with fewer resources, the acquisition signals a clear direction forward—one where sustainability is not just a goal, but a core driver of success.
