Description of the Business

of the most traded dividend index futures in Europe and more than 335 single stock dividend futures (including 68 contracts on US names), making up the broadest offering in Europe. Total return product: a listed solution to access implied equity repo The Total Return Future (“TRF”) on the CAC 40® Index launched in October 2018 has been developed by Euronext in order to meet clients’ need for a listed solution to trade total return swaps. With increased capital requirements being imposed by Basel III and EMIR, the new total return future contract offers strong netting advantages while providing a transparent and secure trading environment to access the implied equity repo rate on the constituents of the CAC 40 index. Euronext has been the first exchange to launch a TRF on a national benchmark. Commodity Derivatives Euronext is a leading provider of agricultural commodity derivatives with several of the Company’s contracts established as global price benchmarks for the international commercial and financial community. The main achievement of the 2019-2021 period was to improve liquidity and volumes by attracting new customers to the contracts. 2021 beats the previous year’s record year in Euronext’s 27-year franchise. Euronext made a strong development to push concentrating on both the mainly European commercial clients and also with a set of focused incentive programmes for international financial operators. This delivered concrete results including: n record participation of financial users representing in 2021 up to 27% of trading volumes; n record physical delivery of the May 2021 milling wheat contract with over 250,000 tonnes of wheat delivered and transferred between buyers/sellers; n record daily volume on milling wheat on 13 August 2021: 154,450 lots; n record daily volume reached for the corn futures contract on 30 November 2021: 10,332 lots; n record month for total volume with 2,402,537 futures and options traded in November 2021 (+2.4% compared to the previous record month in January 2021). The volumes of the flagship milling wheat futures contract grew by 17% in 2021 and reached an average level of more than 58,000 lots traded on a daily basis, representing the equivalent of 2.9 million tonnes of wheat or 5.5 times the total quantity of EU milling wheat production traded over the course of the year. The rapeseed futures contract grew by 24% over the year while the corn contract gained significant traction on the back of new Dunkirk and Ghent delivery silos, with a growth of 47% over the year. The 2024 commodity development strategy builds on recent activity and focuses on: n the launch of a cash-settled platform starting with outright contracts and then extending to more complex spread-based contracts. Durum wheat is the first of these outright priced contracts followed by the integration of the existing Fish Pool cash-settled contract, and the franchise is looking at the possibility of ESG contracts;

n improvement of the current offer to clients with some new technical upgrades. This will improve the existing performance and helps with the inclusion of Euronext’s flagship milling wheat futures contract in commercial indices; n flexibility in Euronext’s market making and incentive programmes with an internal clearing solution, Euronext Clearing, where Euronext could also continue to improve its contract physical delivery and settlement processes (1) . Derivatives Trading Members Trading members in Euronext’s derivative markets are either dealers, brokers or both. Their activities range from retail broking, investment banking, dealing, algorithmic and high frequency trading to international physical trading. The Group’s client base comprises 169 direct trading members as of 31 December 2021 and is significantly diversified both in terms of types of clients and geographic coverage. Trading members can also become market makers or liquidity providers, which is crucial to the good functioning of the price formation mechanism for derivative instruments. In such cases, the parties enter into an agreement with Euronext, specifying their obligations in terms of displayed liquidity and spreads. Market makers and liquidity providers are able to place several orders at the same time through the use of mass quotes, allowing these trading members to send buy and sell orders for many contract months using only one message, leading to optimal efficiency in updating Euronext’s full range of derivatives prices in a timely manner. Derivatives Average Daily Volume by Geographic Origin The average daily volume on Euronext’s derivatives markets for the last twelve months ended 31 December 2021, and pro forma for the Borsa Italiana trading volumes, reached 733,116 contracts, decreasing -6.2% compared to 2020 (pro forma the trading volumes of Borsa Italiana) and representing a total open interest of 22.8 million contracts at the end of December 2021.
