Ring International Holding AG (RIH) is a privately owned Austrian industrial group with long-standing expertise in managing, restructuring and optimising companies, particularly in the metal processing sector. The competence of RIH relates to the acquisition and sustainable development of companies.

In its 20-year corporate history, RIH has transformed into one of Austria’s most dynamic holding companies with sales of up to € 500 million and around 3,000 employees. In 2017, RIH decided to focus entirely on the metal processing sector in order to strengthen its existing competences.

At the end of 2018, the acquisition of BOA Group, therefore, represents a logical step forward towards the further development of RIH’s history. The harmony between the industrial experience of RIH and the excellent technological expertise of the BOA Group will lay down the foundations for a sustainable and stable corporate development, both in the automotive and industrial sector.
