Bangalore-based Infosys was founded in 1981 by seven people and today has revenues of over USD 7 billion and employs more than 1.55 lakh people.
The globalisation of the Indian technology sector was pioneered by Infosys that now represents 24 percent of Indian exports and 13 percent of BSE benchmark index Sensex.
The Euronext listings are intended to attract investors based outside of India and the US, particularly in Europe, to provide greater access to Infosys' ADS among European fund managers.
