MILAN -- The floor of the stock exchange here, the Piazza Affari, was electrified Friday by talk of a bid for Telecom Italia ( TI), the sixth-largest telecommunications company in the world and the second-largest in Europe. And the suitor is none other than Olivetti, the former computer producer based in Ivrea, Italy. Olivetti said its board will meet Sunday to discuss its interest in Telecom Italia. According to insiders at Piazza Affari, Olivetti Sunday will launch a tender offer for the former state telecom giant. In midafternoon trading Telecom Italia ADRs were up 6 5/16, or 6.3%, at 106 3/8, as reports of a probable bid began to hit the newswires. The target price is rumored at 10 to 11 euros per Telecom Italia share, which would represent a 10%-15% premium to Telecom Italia's closing price in Milan today of 9.4 euros, a new high. But where will Olivetti turn to finance such a rich bid? The most likely scenario, according to observers, is that Olivetti will sell its majority stakes in two operations (cellular phone company Omnitel and long-distance carrier Infostrada) to its German partner, Mannesmann. That will do for a start, but the balance of the funding -- some 80% -- is expected to come from a pool of banks including Chase Manhattan and Donaldson Lufkin & Jenrette. Financial advisers for Olivetti will be Mediobanca and Merrill Lynch. The question remains: What is the upside for Olivetti? Telecom Italia ADRs have risen 77% since their early October lows. Some observers say that Olivetti's owners, including a group of Italian industrialists who own a 13% stake and who are led by Roberto Colaninno, are interested in expanding their holdings. Telecom Italia was privatized last year, though the government has retained a "golden share" representing a large voting interest. That is important because most observers think that only an Italian company such as Olivetti would receive the government's approval in a takeover. Possible suitors named in rumors earlier this week included Bell Atlantic ( BEL) and MCI WorldCom ( WCOM), but these reports were subsequently denied. Observers say it is reasonable to expect Telecom Italia to seek a higher price if and when Olivetti bids.
