Ametalis strengthens its Nordic position – welcomes Westberg and Natur og Samfunn to the group and receives MVI as new principal owner

Ametalis acquires Westberg Vibrations- och Omgivningskontroll AB and Natur og Samfunn AS.

Through these two acquisitions, Ametalis works to build a leading Nordic platform for environmental and sustainability services. In connection with these transactions, Ametalis was also acquired by MVI. With MVI as a strategic partner, we look forward to accelerating the growth of the group, both through organic growth and further acquisitions focusing on quality, expertise and societal benefits.

We welcome Westberg Vibrations- och Omgivningskontroll AB, active in Sweden, and Natur og Samfunn, based in Norway to the group. Both Westberg and Natur og Samfunn will operate under their existing brands and with unchanged management, but now with access to new resources, collaborations and development opportunities within the Ametalis Group.

“We welcome Westberg and Natur og Samfunn to Ametalis. They are both strong entrepreneur-driven companies with specialist expertise that are fully in line with our ambition to bring together the Nordic region’s leading expertise in environmental and sustainability. With MVI as a new owner, we strengthen our capacity to grow faster and smarter together.”

Kim Lehmusvuori, CEO Ametalis
