News Releases

As NYSE Euronext through its indirect wholly owned subsidiary NYSE Euronext (Holding) N.V. will hold more than 95% of the Euronext share capital as of 27 April 2007, it plans to initiate, through its subsidiary, a compulsory acquisition procedure in accordance with the Dutch civil code. In this compulsory acquisition, the price to be paid for Euronext shares will be paid in cash only, in an amount determined by the Enterprise Chamber of the Amsterdam Court of Appeals. It is anticipated that this process will take several months to complete.

Notes to editors:
In the exchange offer, Euronext shareholders were permitted to exchange each of their Euronext shares for €21.32 in cash and 0.98 of a share of NYSE Euronext common stock (the standard offer consideration). The exchange offer also included a mix and match election feature, subject to pro-ration, that permitted Euronext shareholders to make an election to receive 1.2633 shares of NYSE Euronext common stock (the stock election) or €95.07 in cash (the cash election). The stock election and cash election were subject to pro-ration to ensure that the total amount of cash paid, and the total number of shares of NYSE Euronext common stock issued, in the exchange offer would be equal to the total amount of cash and number of shares that would be paid and issued if all tendering Euronext shareholders received the standard offer consideration.
