Italian shipyard giant Fincantieri has criticised media rumours of a deeper probe into its takeover of STX France (Chantiers de l'Atlantique), which later turned out to be true.

It said several outlets published reports of an "alleged decision by the EU antitrust authorities to commence a further in-depth analysis" of the deal.

"Fincantieri strongly disapproves of such rumours, which have also negatively affected its share price today," it added.
