GENERAL DESCRIPTION OF THE COMPANY AND ITS SHARE CAPITAL

Share Classes and Major Shareholders

Letter Agreement In addition to the renewed Reference shareholders Agreement, the Letter Agreement of 4 June 2014 between Euronext and its Reference shareholders, as supplemented on 25 March 2015, has been amended and extended. The focus of the revised Letter Agreement dated 13 June 2017 is to strengthen the regular dialogue between Euronext and its Reference shareholders, addressing (i) the right of the Reference shareholders to retain one third of the Supervisory Board seats, (ii) the use by Euronext of the delegated authorities for the issuance / repurchase of shares, with the possible exclusion or restriction of pre-emption rights, (iii) the process of communication between Euronext and the Reference shareholders, which includes periodical meetings on topics including strategy, governance and financing structure; and (iv) the involvement of the Reference shareholders in the selection procedure in case of any vacancies for the CEO, the COO or Supervisory Board positions.

any substantial holding and gross short positions in issuing institutions and shares with special controlling rights have to be notified. An issuing institution is: a public limited company ( naamloze vennootschap ) incorporated under Dutch law whose (depositary receipts for) shares are admitted to trading on a regulated market in the Netherlands or in another Member State of the European Union or an EEA State, or a legal entity incorporated under the law of a state that is not an European Union Member State and whose (depositary receipts for) shares are admitted to trading on a regulated market in the Netherlands. As soon as the substantial holding or short position equals or exceeds 3% of the issued capital, the holder should report this. Subsequently, it should notify the AFM again when its substantial holding or short position consequently reaches, exceeds or falls below a threshold. This can be caused by the acquisition or disposal of shares by the shareholder or because the issued capital of the issuing institution is increased or decreased. Thresholds are: 3%, 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 75% and 95%. The duty to notify applies to legal entities as well as natural persons.
