The transaction, which is worth €64.5m, has been approved by the Italian Authority for Markets and Competition.
The deal reduces Astaldi’s stake in Metro 5 to 2%. The other shareholdings remain unchanged - Ansaldo STS holds 24%, ATM 20%, Alstom 9.4% and Hitachi Rail Italy 7.6%.
The acquisition is part of the FS’s industrial plan for 2017-2026, which seeks to develop integrated mobility in major urban centres. In this context, the planned extension of Line M5 to Monza and Settimo Milanese could now benefit from early funding and implementation.
The 12.8km line from Bignami to San Siro Stadium opened in phases between 2013 and 2015 and serves 19 stations, including interchanges with three metro lines and main line services.
Mr Roberto Passalacqua remains president of the Metro 5 steering committee and Mr Amerigo Del Buono will continue as CEO. Mr Stefano Pierini, Mr Guglielmo Casciaro, Mr Luca Silveri Gentiloni and Mrs Paola Barbaglia have joined the board as advisors.
