Presentation of the Group 1 Description of the Business

Euronext owns 66% of Nord Pool, which operates a leading physical power market in Europe. Nord Pool operates both core intraday and day-ahead markets in the Nordics, Baltics, the UK, France, Germany, Belgium, the Netherlands, Austria and Luxembourg Euronext also operates one of the leading structured products trading venues in Europe with over 110,000 instruments available for trading. Euronext’s hybrid market model, also known as the Request For Execution market model, is widely recognised as one of the most advanced market models for trading structured products and more specifically warrants & certificates. In 2020 Euronext released additional features allowing for an optimised and more efficient post-trade model as well as the possibility for investors to trade these instruments until 22:00 CET, paving the way for a truly pan-European structured products market. “United in Diversity” with an Open Federal Model Euronext is the only European exchange operating across multiple jurisdictions with a harmonised regulatory framework, a Central Order Book for its exchanges in Amsterdam, Brussels, Dublin, Lisbon, Oslo, Paris and soon Milan and a single trading platform offering access to all markets through a single connection. The Central Order Book consolidates liquidity in each multi-listed security to tighten spreads and increase market depth and achieves optimal price formation. Issuers listing on more than one of the Group’s markets benefit from enhanced visibility, qualification for inclusion in more local indices and greater exposure for their volumes and prices.

The Group has generated sustainable and diversified cash flows across institutional, high frequency and algorithmic trading, own account, agency brokerage and retail client classes.
