Technology group Wärtsilä has 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.
