ITEM 8.01. OTHER EVENTS.

     On February 15, 2007, NYSE Group, Inc. and Euronext N.V. issued a press release announcing that NYSE Euronext, Inc., through its indirectly owned subsidiary NYSE Euronext (Holding) N.V., will commence an exchange offer on February 15, 2007 for all of the outstanding shares of Euronext. A copy of the press release is attached to this current report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference.

     The standard offer consideration that Euronext shareholders will receive for each Euronext share that they tender in the exchange offer is €21.32 in cash, without interest, and 0.98 of a share of NYSE Euronext common stock. In lieu of receiving this standard consideration, Euronext shareholders have the right to elect to receive for each of their tendered Euronext shares:

·	1.2633 shares of NYSE Euronext common stock (which is referred to as the stock election); or
·	€95.07 in cash, without interest (which is referred to as the cash election).

     The stock election and cash election are subject to proration and allocation to ensure that the total amount of cash paid, and the total number of shares of NYSE Euronext common stock issued, in the offer will equal 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.

     The exchange offer will close on March 21, 2007, unless it is extended, and the settlement and delivery of the exchange offer, as well as the admission of the NYSE Euronext common stock on Euronext Paris and on the NYSE, is expected to take place on April 4, 2007.

     The French offering materials, which include NYSE Euronext’s French offer document (note d’information registered under No.07-018 on January 18, 2007)), Euronext’s French response document (note en réponse registered under No.07-019 on January 18, 2007), NYSE Euronext’s French registration statement (document de base registered under No.I.06-184 on November 30, 2006) and the two separate updates on the characteristics of NYSE Euronext and Euronext dated February 14, 2007, have been filed with the French Autorité des marchés financiers (or the AMF) in France and are available on the AMF’s website at www.amf-france.org or on Euronext’s website at www.euronext.com.

     The U.S. offering materials, which include NYSE Euronext’s registration statement on Form S-4 (Registration No. 333-137506) filed with the U.S. Securities and Exchange Commission (or the SEC) and a related prospectus that will be filed with the SEC, will be available on the SEC’s website at www.sec.gov and on www.nyse.com. U.S. holders of Euronext shares should read the prospectus when it becomes available, as opposed to the French offering materials.
