At FMC Technologies, Inc.’s (“we” or “our”) 2012 Annual Meeting of Stockholders held on May 2, 2012 (the “Annual Meeting”), our stockholders approved amendments to our Amended and Restated Certificate of Incorporation, as described in our Proxy Statement dated April 2, 2012, relating to the Annual Meeting. These amendments provide for the phased elimination of our classified Board of Directors. Directors elected prior to the filing of the amendment with the Secretary of State of the State of Delaware (including directors elected at the Annual Meeting) will complete their three-year terms and, thereafter, such directors or their successors will be elected to one-year terms. Therefore, beginning with our 2015 Annual Meeting of Stockholders, the declassification of the Board will be complete, and all directors will be subject to annual election to one-year terms.

We filed a Third Certificate of Amendment to our Amended and Restated Certificate of Incorporation reflecting the amendments with the Secretary of State of the State of Delaware on May 3, 2012 (the “Certificate of Amendment), which became effective upon filing. The foregoing description of the Certificate of Amendment does not purport to be complete and is qualified in its entirety by reference to the Certificate of Amendment, a copy of which is filed as Exhibit 3.1 to this Current Report on Form 8-K and incorporated into this Item 5.03 by reference.

We held our Annual Meeting for the purpose of (1) electing four directors; (2) ratifying the appointment of KPMG LLP as our independent registered public accounting firm for the year ending December 31, 2012; (3) approving our 2011 executive compensation program; (4) approving an amendment to our Amended and Restated Certificate of Incorporation to provide for the annual election of all directors; and (5) voting on any other business properly brought before the meeting. Of the 239,074,012 shares of our Common Stock outstanding and entitled to vote at the Annual Meeting, 211,967,785 shares were present either in person or by proxy.

The following are the final results of the Annual Meeting.

The following directors’ terms of office continued after the meeting: C. Maury Devine, Eleazar de Carvalho Filho, John T. Gremp, Thorleif Enger, Claire S. Farley, Thomas M. Hamilton, Joseph H. Netherland and Richard A. Pattarozzi.
