Il Sole 24 Ore, the Italian publisher of the country's largest financial newspaper, has appointed nine banks to advise on its €300m ($433m) initial public offering, an unusually high number, after gaining approval for the share sale from the Milan stock exchange.

The Milan-based company will price its shares on November 30. Mediobanca and UBS are coordinating the sale, with Lehman Brothers, Banca IMI, BNP Paribas, Citigroup, Goldman Sachs, Merrill Lynch and Unicredit as bookrunners.
