Europe's biggest car maker Volkswagen is poised to complete its purchase of Porsche by August 1.
The German firm has agreed to buy the remaining 50.1% of Porsche AG that it does not already own from holding company Porsche SE.
A price of 4.46 billion euro (£3.5bn) has been agreed, plus one Volkswagen share.
The deal will also redefine the complex ownership arrangement that currently exists between the two companies.
Porsche SE holds a major stake in Volkswagen and the two firms share several executives, plus a number of major shareholders.
Volkswagen, which is based in Wolfsburg, already includes brands such as Audi, Seat, Bugatti and Bentley, along with truck manufacturers MAN and Scania.
