Kosta became part of the Afors group in 1971, along with Afors and Boda, and later Johansfors. the group was bought by Upsala-Ekeby in 1975, and renamed Kosta Boda AB in 1976. Kosta Boda merged with Orrefors in 1990 to become Orrefors Kosta Boda, and in 1997 became part of The Royal Scandinavian Group.
