Prada SpA, the famous Italian luxury brand, is reportedly gearing up to seek a $1 billion valuation at the Milan listing. The luxury retailer has partnered with Goldman Sachs Group Inc. on early preparations to enter the listing. Prada would be working together to raise funds by offering new shares in Milan. The brand is already in the Hong Kong-listed luxury group and is now eyeing a dual listing in Europe to grow its investors pool as some funds can only place money into the US or European stocks.
