Volkswagen has acquired the operating business of Porsche Holding Salzburg (PHS) in accordance with previous announcements.
The transfer of the automobile trading company took place at a value of €3.3 billion on March 1.
The registered office and corporate headquarters will remain in Salzburg.
Volkswagen is now completing the next step towards the creation of an integrated automotive group of Volkswagen and Porsche.
"The business performance of Porsche Holding Salzburg is outstanding," Volkswagen CEO, Martin Winterkorn, said. "It is one of the world's most efficient and profitable automobile trading companies and will therefore significantly strengthen the Volkswagen Group's sales activities."
Winterkorn said PHS had industry-leading systems and processes and enormous experience in the retail sector.
"Where meaningful, we will be transferring this know-how to the group thereby further enhancing the performance of our overall sales activities," he said.
Volkswagen is acquiring all automobile operations of PHS such as the wholesale and retail business, Porsche Informatik, Porsche Bank, Porsche Immobilien and Porsche Versicherung as well as PGA Motors, headquartered in Paris.
Volkswagen board member for sales, Christian Klingler, said under the Volkswagen Group umbrella PHS will retain its status as an independent organisational unit and continue with its business model unchanged, and that all assets remain intact.
That also applies to the automobile trading business relating to all non-group brands.
