German car making giant Volkswagen (VW) has said it is aiming for a valuation of up to €75bn ($75bn; £65.8bn) for Porsche when the luxury brand is floated on the stock market.
Trading in the shares is due to start in Frankfurt on 29 September.
The share sale is set to be Germany's second-largest ever initial public offering (IPO).
VW said in a statement to investors that it will price preferred shares in the flotation of Porsche at €76.50 to €82.50 per share, which would give the sportscar maker a stock market valuation of €70bn to €75bn.
At the upper end of the range it would be Europe's third-largest IPO on record.
However, the figures announced on Sunday fell short of an earlier valuation target - as much as €85bn - amid investor concerns over rising interest rates and a potential global recession.
VW said it will raise as much as €9.4bn from the share sale, which will help pay for its shift to electric vehicles and spending on software development.
