About Euronext N.V.
Since its creation in 2000, Euronext has been working towards the consolidation of financial markets by integrating local markets across Europe to provide users with a single market that is broad, highly liquid and extremely cost effective.
After the initial three-way merger of the local exchanges of Amsterdam, Brussels and Paris, Euronext acquired the London-based derivatives market LIFFE and merged with the Portuguese exchange in 2002. The implementation of Euronext’s horizontal market model, designed to generate synergies by incorporating the individual strengths and assets of each local market, has proved that the most successful way to merge European exchanges is to apply global vision at a local level. This unique business model has been implemented on all of Euronext’s markets, and covers technological integration, the reorganization of activities into cross-border, streamlined strategic business units (SBUs) and the harmonization of market rules and the regulatory framework.
Euronext’s IT integration was completed in 2004, when a four-year migration plan resulted in harmonized IT platforms for cash trading (NSC), derivatives (LIFFE CONNECT®) and clearing. As a result, every market participant now has a single point of access to trading. Another step forward in the rationalization of Euronext’s IT structure was made in 2005 with the creation of Atos Euronext Market Solutions (AEMS), an IT services-related vehicle between Euronext and Atos Origin that is a leading global provider of technology services to the capital markets.
