Wärtsilä has announced the divestment of its Water & Waste business to the Swedish investment firm Solix Group AB. This strategic decision marks the completion of Wärtsilä’s Portfolio Business divestments, aiming to streamline operations and unlock further value.
The Water & Waste division offers a comprehensive suite of environmental solutions for marine water and waste management, including ballast water treatment and wastewater systems. These technologies are designed to enhance operational efficiency, ensure regulatory compliance, and improve environmental performance throughout a vessel’s lifecycle.
Key Takeaways
- Wärtsilä divests its Water & Waste business to Solix Group AB.
- The transaction is expected to complete in Q3 2026, subject to approvals.
- Water & Waste generated EUR 54 million in annual revenue in 2025.
- This divestment concludes Wärtsilä’s strategic exit from its Portfolio Business.
Strategic Rationale Behind the Divestment
Wärtsilä’s Water & Waste business has operated independently within the company’s Portfolio Business segment, with the objective of accelerating performance improvements and realising value through divestment. The company views this sale as a crucial step in its ongoing strategic realignment.
Bernd Bertram, Head of Portfolio Business at Wärtsilä, expressed confidence in the future of the divested unit. "Wärtsilä Water & Waste has developed a broad range of specialised and proven environmental solutions for marine applications," Bertram stated. "Building on our earlier collaboration with Solix, Water & Waste will be well positioned to develop further and ensure continued value creation for its customers and highly skilled team."
Financial and Operational Impact
In 2025, the Water & Waste business reported an annual revenue of EUR 54 million. The completion of this transaction will signify Wärtsilä’s full withdrawal from its Portfolio Business segment. The deal is anticipated to be finalised in the third quarter of 2026, pending the necessary regulatory approvals.
Wärtsilä, a global leader in innovative technologies and lifecycle solutions for the marine and energy sectors, continues to focus on sustainable technology and services to drive decarbonisation and improve economic performance for its customers.
