German automaker Volkswagen confirmed Monday it would soon list its Porsche sports car in what will likely be Europe’s largest initial public offering.

The firm is targeting a listing in Frankfurt at the end of this month or the beginning of October, company officials said.

The Qatar Investment Authority, one of Volkswagen’s largest shareholders, has “expressed strong interest” in buying almost 2.5% of the Stuttgart-based subsidiary’s 12.5% tranche that will go up for sale directly to new investors.

The Porsche-Piech families have agreed to buy another 12.5% of Porsche shares at the IPO price plus a 7.5% premium.

The IPO listing could push Porsche’s valuation up to about $84 billion, per analysts.
