NOTE 40 EVENTS AFTER THE REPORTING PERIOD

Operational riskmay be impacted in the case of a successful targeted physical or cyberattack directly on Market infrastructures or indirectly in the ecosystem of Euronext, and results in the extended disruption of the market, the Groupmay face significant financial and potentially reputation losses. Operations may be impacted by high volatility given the evolving situation or via suppliers/contractors who cannot provide services. The invasion of Ukraine is expected to add inflationary pressure particularly for commodities exported by Russia which may impact the cost base of the Group. Furthermore, a protracted war and disruptions to Russian oil and gas exports may trigger a global energy shock resulting in negative consequences and in a worst case scenario a European recession, which may negatively impact the Group results. The Group is closely monitoring further developments and will continuously adapt its risk assessment to the current situation.

The significant events that occurred between 31 December 2021 and the date of this report that could have a material impact on the economic decisions made based on these Financial Statements are listed below: Developments on the Russian invasion of Ukraine Following the Russian invasion of Ukraine in early 2022, the Group has performed a detailed initial assessment of the measures taken by the European Union/ European Economic Area, United Kingdom and United States related to sanctions on Russia and Belarus and their impacts on the Group, and has taken appropriate action. The sanctions list is continuously monitored closely in discussion with regulators to ensure that sanctions are not breached. Euronext does not own any entities in Russia, Belarus or Ukraine and the Group has a limited activity with clients and/or entities based in those countries. Similarly, the Group does not have critical vendors that are linked to Russia, Belarus or Ukraine. The impact to business and vendor support is limited.
