The volume of the flagship milling wheat futures contract grew by 28% in 2020 and reached a level of more than 50,000 lots traded on a daily basis, representing the equivalent of 2.5 million tons of wheat or five times the milling wheat quantity EU production traded over the course of the year. The Rapeseed futures contract grew by 7% on the year while the corn contract gained significant traction on the back of the new Dunkirk and Ghent delivery silos, with a growth of 18% over the year. These futures contracts have obtained international recognition status, both of which have been included in the main global commodity indices (S&PWorld Commodity Index, Rogers International Commodity index), making them the first non- U.S. grains contracts to be included in these global indices. The commodity team continues to build on the strategy announced in 2018 which is articulated around: n focus on building existing core contracts to their full potential and, in particular, leveraging on the Euronext MATIF brand for grains and oilseeds. EIMwith trade finance and repos along with location swaps will become a core element of the agricultural franchise and generate growing revenue streams over the next 3-5 years. It will protect Euronext physically delivered contracts, which have been suffering over the last few years from being exposed as the only major player without a digital contract delivery system; n Cash Settled platform will allow the franchise to extend from the current three grain products offering and enable listing and trading of a number of desired price reference contracts, as simpler cash settled products when appropriate ( e.g. when physical delivery is not a key or desired pricing mechanism); n monitoring of opportunities for non-organic growth, blockchain applications linked to EIM, etc .: with the recent acquisitions in Norway, the commodities franchise is becoming a much stronger andmore diverse actor globally, building on the historic Agricultural footprint to soon offer salmon futures and new ideas in Power. 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 153 direct trading members as of 31 December 2020 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 formationmechanism 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.

More than 234 equity options and over 382 equity futures can be traded on Euronext, making the Company one of the leading markets for equity derivatives trading. Equity options trading has historically been particularly active in Amsterdam due to high retail participation. Equity index derivatives allow holders to hedge against, or take position on, changes in the future level of a particular index, the investor paying or receiving a cash sum representing its loss or gain on the future or option. Euronext’s equity index derivatives allow customers to hedge against fluctuations in a range of European stock market indices and the European equity market as a whole, and many are available as weekly or daily contracts as well as the more usual monthly contracts. Euronext’s flagship equity index products include the CAC 40® index futures contract, which is the second most traded national index future in Europe, in terms of number of contracts traded, and the AEX® Index options contract, which is one of the most on-exchange traded national index options in Europe. Euronext’s mini index derivatives (’minis’) allow investors to follow the same investment strategies but with less initial margin or a smaller trading amount. Dividend Products: A New and Rapidly Growing Asset Class Dividend index futures and stock dividend futures allow holders to hedge against, or take position on, changes in the dividend of a particular index or underlying share. Euronext’s flagship dividend products include the CAC 40® dividend index futures, which is one of the most traded dividend index futures in Europe and more than 290 Single Stock Dividend Futures (including 56 contracts on US names), making up the broadest offering in Europe. 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 is the first Exchange to launch a TRF on a national benchmark.
