Porsche and Piëch families merged Porsche into VW to escape €10B of debt

Porsche SE, controlled by the Porsche and Piëch families, tried to take over Volkswagen in 2008 and ended up with 51% of VW's shares but more than €10B of debt as the financial crisis hit.

In August 2009 the two families — who together hold 100% of Porsche SE's voting shares — agreed to reverse course: Volkswagen would buy Porsche's car business, and the sale would pay off most of the debt.

The deal closed in stages: VW agreed in July 2012 to buy the remaining 50.1% of Porsche AG for €4.46B, ending a seven-year saga that had divided the families. Porsche SE survived as a holding company with a large Volkswagen stake.

VW paid €4.46B for the remaining 50.1% of Porsche's car business in 2012; Porsche SE survived, repaid its debts and remained a profitable holding.

The families accepted that the takeover attempt had failed instead of doubling down.

Selling the car brand to VW raised the cash needed to clear the debt.

The families kept control of Porsche SE, preserving their long-term wealth vehicle.

Reuniting the two clans ended feuds that had blocked rational decisions.

When a family's ambition nearly destroys the firm, merging with the target can be the rescue: the Porsche and Piëch families traded control of the car brand for survival of the holding.

Porsche AG became a fully owned Volkswagen brand in August 2012 and its profits flowed through the group, while Porsche SE remained Volkswagen's anchor shareholder and paid dividends to the two families. The structure still exists today, with the families in control of Porsche SE.
