Banca IMI is part of Italy's biggest retail bank Intesa Sanpaolo, which in turn is NTV's biggest shareholder with a 19 percent stake. NTV held an initial meeting with the three banks on Monday, one of the sources added.

NTV, run by former Ferrari chairman Luca Cordero di Montezemolo and former Telecom Italia (>> Telecom Italia) chief Flavio Cattaneo, is expected to list in the first half of 2018, the sources said.

The company last week reported nine-month earnings before interest, taxes, depreciation and appreciation (EBITDA) of 114.8 million euros ($135 million), up 79 percent on the previous year. Sales were up 26 percent to 329 million euros.
