Technology group Wärtsilä has today completed two divestments: divesting the Gas Solutions business to Mutares SE & Co. KGaA, following the agreement announced on 22 December 2025, and divesting Water & Waste business to Solix Group AB, following the agreement announced on 5 February 2026.

Gas Solutions, with the annual revenue of EUR 394 million in 2025, provides its customers with innovative systems and comprehensive lifecycle solutions for the gas value chain. Water & Waste, with annual revenue of EUR 54 million in 2025, focuses on environmental solutions across the full spectrum of water and waste management at sea. The financial performance of both businesses has been below Wärtsilä’s profitability targets.

These business units with their employees will transfer to the respective new owners on 1 June 2026.

By completing the divestments of the Gas Solutions and Water & Waste, Wärtsilä Portfolio Business will have no remaining business activities.

“After establishing the Portfolio Business in early 2020, we have now divested of all the business units moved to Portfolio Business over the years and successfully executed on our strategy to accelerate performance improvements and unlock value to Wärtsilä through divestments. As a result of these divestments, Wärtsilä is becoming a more focused and profitable company. We wish our former colleagues and the new business owners the best of success,” says Håkan Agnevall, President & CEO, Wärtsilä.
