The Porsche Automobile Holding SE is responsible for the stock of the operating subsidiary, Dr. Ing. h.c. F. Porsche AG, and for the investments in Volkswagen AG. With the new structure, Porsche ensures that the autonomy and independence of the traditional Stuttgart-based company remain fully protected. This is the main purpose of separating holding and operating activities. At the same time, the holding also represents a single company responsible for the management of stock.
