Leonardo CEO Dismisses Renzi's Idea of Tie-Up with Fincantieri
The two groups are both controlled by Italy's Treasury and cooperate in the military shipbuilding sector.
According to Renzi, who has no ministerial role in the government but whose political movement holds the balance of power in the ruling coalition, a merger would create a national champion and increase Rome's ability to invest in the defence and space sectors.
Attending a public event, Leonardo CEO Alessandro Profumo said further diversifying the company's business could be counter-productive.
"In some cases putting together many businesses could become a limit," Profumo told reporters on the sidelines of an event.
Profumo added that some critics already saw Leonardo's operations as too far-ranging. The group's business areas currently include helicopters, aircrafts, aerostructures, electronics, cyber security and space.
