Borsa Italiana

Borsa Italiana (English: Italian Stock Exchange) or Borsa di Milano (English: Milan Stock Exchange), based in Milan at Mezzanotte Palace, is the Italian stock exchange. It manages and organises domestic market, regulating procedures for admission and listing of companies and intermediaries and supervising disclosures for listed companies.

Following exchange privatisation in 1997, the Italian Bourse was established and became effective on 2 January 1998. On 23 June 2007, the Italian Bourse became a subsidiary of the London Stock Exchange Group. This changed on 9 October 2020, when a €4.3 billion deal was agreed between the London Stock Exchange Group and pan-European stock exchange group Euronext. Euronext's acquisition of the Italian Bourse was completed on 29 April 2021. It is expected Italian Bourse will be rebranded as Euronext Milan in due course.

Borsa Italiana is also informally known as Piazza Affari (lit. 'Business Square'), after the city square of Milan where its headquarters (the Palazzo Mezzanotte building) is located.

Borsa Italiana is chaired by Claudia Parzani, and Fabrizio Testa is the CEO.

Borsa Italiana is regulated by the Commissione Nazionale per le Società e la Borsa (CONSOB), an agency of the Ministry of Economy and Finance, based in Rome. As of April 2018, overall capitalisation for listed companies on Borsa Italiana was worth €644.3 billion, representing 37.8% of Italian GDP.

The Borsa di commercio di Milano (Milan Stock Exchange) was established by Eugène de Beauharnais, viceroy of the Napoleonic Kingdom of Italy, through decrees dated 16 January and 6 February 1808. It overtook the historically poorly regulated Borsa di Genova, later becoming the Italy's main stock exchange after the Panic of 1907.

It operated under public ownership until 1998, when it was privatized. In 1997, all the Italian stocks were merged. Before that year, other smaller stocks exchanges were based in Naples, Turin, Trieste, Venice, Genoa, Florence, Bologna, Rome, and Palermo. In 1991, the electronic exchanges were approved, and in 1994, the market with grids (A, B, C) was abolished. In Milan were also the currencies exchange rates fixing and the commodities fixing.

On 1 October 2007, Borsa Italiana was merged with the London Stock Exchange in an all-share takeover, thus becoming part of the London Stock Exchange Group. In March 2016, the London Stock Exchange Group announced the agreement to merge in an all-stock deal with Deutsche Borse, but was subsequently blocked by the EU Competition Regulator.
