Denis O’Brien founded Esat Telecom Group (“Esat”) in 1991 to compete against the former state-owned telephone company in Ireland, Eircom plc. In October 1997, Esat, of which Denis was Chairman and Chief Executive Officer, listed on Nasdaq (New York), Easdaq (Amsterdam) and the Iseq (Dublin). Esat, over a five-year period, raised $1 billion in equity and bonds in a number of successful U.S. and European public offerings.
Esat established itself as the number two telecommunications company across the full spectrum of telecommunications services (corporate and residential), fixed-line, GSM mobile, data and internet services and brought real competition and choice to the Irish telecommunications market. Esat Telecom Group plc was sold to British Telecom Group plc in January 2000 for $2.8 billion. Denis was voted Ireland’s Entrepreneur of the Year in 1998 in the inaugural running of the worldwide competition organised and sponsored by Ernst & Young.
