NYX Nyse Euronext

At the Company’s annual stockholders’ meeting held on April 28, 2011, NYSE Euronext (NYX) shareholders:

• Elected the full slate of 16 director nominees to the Company’s Board of Directors, with an average approval rate of 80% of votes cast,
• Ratified the appointment of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for 2011,

• Approved on an advisory, non-binding basis, the Company’s executive compensation,
• Approved on an advisory, non-binding basis, a frequency of every one year for holding the non-binding, advisory vote on executive compensation,
• Approved a stockholder proposal regarding the power of stockholders to call special meetings, and
• Approved a stockholder proposal regarding stockholder action by written consent.

To be approved, the proposal to adopt a simple majority vote requirement to amend or repeal certain provisions in the Company’s charter required the affirmative vote of at least 80% of the shares of our outstanding stock entitled to be voted at the meeting. The proposal received the support of 94.66% of the shares of our outstanding stock actually voted but only 75.45% the shares of our outstanding stock entitled to be voted, and therefore the proposal was not approved.

Among the 16 elected directors is Dominique Cerutti, the Company’s president and deputy chief executive officer and head of Global Technology, who is a newly elected member of the Board. Mr. Cerutti has considerable experience in leading the business operations of a global technology company, where he served in several senior leadership roles.
