On 1 January 2016, Leonardo-Finmeccanica became a single industrial company by integrating the activities of its subsidiaries AgustaWestland, Alenia Aermacchi, DRS Technologies, Selex ES, Oto Melara and WASS. The company is organised into seven divisions (Helicopters, Aircraft, Aerostructures, Airborne & Space Systems, Land & Naval Defence Electronics, Defence Systems, Security & Information Systems) and is also the parent company and corporate centre for the subsidiaries and joint ventures, Telespazio, Thales Alenia Space, MBDA and ATR. Leonardo-Finmeccanica is listed on the Borsa Italiana and is a constituent of the FTSE MIB and Dow Jones Sustainability Indices.
As of April 2016, the company was known by the transitional name of Leonardo-Finmeccanica as part of the restructuring process of the company carried out by CEO Mauro Moretti from the beginning of his mandate in 2014. The company changed its name to Leonardo S.p.A. on 1 January 2017, after the Italian inventor Leonardo da Vinci.
The company was established in 1948 as a subholding for mechanical industry of state owned IRI. Finmeccanica has held for years some historic Italian enterprises, such as Alfa Romeo (automobile), Aeritalia (aerospace) and Ansaldo (engineering). From 1960s to 1980s Italy's defence and aerospace industry was split in different state-holding entities: so EFIM owned the helicopters manufacturer Agusta, the defence company Oto Melara and the electronic enterprise Officine Galileo, whereas STET (another IRI subsidiary) held Selenia, Elsag and SGS Thomson, all electronic enterprises with specializations in security and defense. In 1989 an internal IRI reorganization process brought STET electronic enterprises to Finmeccanica, that from Aeritalia-Selenia merger made up its aerospace subsidiary Alenia.
In 1992 EFIM wound up because of troubled financial situation; so Agusta, Oto Melara, Officine Galileo and Breda passed to Finmeccanica, which became one of the most important Italian industrial groups. Finmeccanica, which was previously fully state owned by IRI, went under a privatization process in 1993, when it was listed in Milan Borsa Italiana.
