On June 16, 2016, FMC Technologies, Inc. (the “Company”) and Technip S.A., a French société anonyme (“Technip”), issued a joint news release announcing that on June 14, 2016 they entered into a definitive business combination agreement (the “Business Combination Agreement”), providing for a business combination among the Company, FMC Technologies SIS Limited, a private limited company incorporated under the laws of England and Wales and a wholly owned subsidiary of the Company (“Topco”), and Technip. A copy of the joint news release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.

The entry into the Business Combination Agreement follows the Company’s announcement on May 19, 2016, of its intention to enter into a business combination with Technip. The May 19 announcement was made on the basis of entrance into a binding memorandum of understanding (the “MOU”) on May 18, 2016 by the Company, Topco and Technip. The MOU provided that, subject to completion of certain employee consultation procedures required under applicable law and certain other customary conditions, the parties to the MOU would enter into the Business Combination Agreement. The MOU provided that the employee consultation procedures were to be completed by September 30, 2016. On June 14, 2016, the parties completed the employee consultation procedures and other conditions precedent to their entrance into the Business Combination Agreement.

Business Combination Agreement

The Business Combination Agreement provides for (i) the merger of Technip with and into Topco (the “Technip Merger”), with Topco surviving the merger, and immediately thereafter, (ii) the merger of a wholly owned indirect subsidiary of Topco (“Merger Sub”) with and into the Company (the “Company Merger” and, together with the Technip Merger, the “Mergers”), with the Company surviving as a wholly owned subsidiary of Topco, in each case subject to the terms and conditions of the Business Combination Agreement. At the effective time of the Technip Merger, each issued and outstanding ordinary share of Technip (the “Technip Shares”), other than Technip Shares owned by Technip or its subsidiaries, will be converted into the right to receive two ordinary shares of Topco (“Topco Shares”). At the effective time of the Company Merger, each share of common stock of the Company (each, a “Company Share”), other than Company Shares owned by the Company, Topco, Merger Sub or their respective subsidiaries, will be converted into the right to receive one Topco Share. Topco will apply to list the Topco Shares to be issued in the Mergers on the New York Stock Exchange and the regulated market of Euronext Paris. Following consummation of the Mergers, former Technip stockholders will own approximately 50.9 percent of Topco and former stockholders of the Company will own approximately 49.1 percent of Topco, on a fully diluted basis.

A more detailed summary of the Business Combination Agreement was included in the Company’s Form 8-K filed on May 19, 2016 and is incorporated by reference herein. The foregoing description of the Business Combination Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Business Combination Agreement, including the exhibits attached thereto, a copy of which is attached as Exhibit 2.1 herewith and is incorporated by reference herein.

Important Information for Investors and Securityholders

Forward-Looking Statements

This communication contains “forward-looking statements”. All statements other than statements of historical fact contained in this report are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Forward-looking statements usually relate to future events and anticipated revenues, earnings, cash flows or other aspects of the Company’s operations or operating results. Forward-looking statements are often identified by the words “believe,” “expect,” “anticipate,” “plan,” “intend,” “foresee,” “should,” “would,” “could,” “may,” “estimate,” “outlook” and similar expressions, including the negative thereof. The absence of these words, however, does not mean that the statements are not forward-looking. These forward-looking statements are based on the Company’s current expectations, beliefs and assumptions concerning future developments and business conditions and their potential effect on the Company. While management believes that these forward-looking statements are reasonable as and when made, there can be no assurance that future developments affecting the Company will be those that the Company anticipates.

Factors that could cause actual results to differ materially from those in the forward-looking statements include failure to obtain applicable regulatory or stockholder approvals in a timely manner or otherwise; failure to satisfy other closing conditions to the proposed transactions; failure to obtain favorable opinions from counsel for each company to the effect of how Topco should be treated for U.S. tax purposes as a result of the proposed transaction; risks associated with tax liabilities, or changes in U.S. federal or international tax laws or interpretations to which they are subject, including the risk that the Internal Revenue Service disagrees that Topco is a foreign corporation for U.S. federal tax purposes; risks that the new businesses will not be integrated successfully or that the combined companies will not realize estimated cost savings, value of certain tax assets, synergies and growth or that such benefits may take longer to realize than expected; failure to realize anticipated benefits of the combined operations; risks relating to

unanticipated costs of integration; reductions in client spending or a slowdown in client payments; unanticipated changes relating to competitive factors in the companies’ industries; ability to hire and retain key personnel; ability to successfully integrate the companies’ businesses; the potential impact of announcement or consummation of the proposed transaction on relationships with third parties, including clients, employees and competitors; ability to attract new clients and retain existing clients in the manner anticipated; reliance on and integration of information technology systems; changes in legislation or governmental regulations affecting the companies; international, national or local economic, social or political conditions that could adversely affect the companies or their clients; conditions in the credit markets; risks associated with assumptions the parties make in connection with the parties’ critical accounting estimates and legal proceedings; and the parties’ international operations, which are subject to the risks of currency fluctuations and foreign exchange controls.

All forward-looking statements involve risks and uncertainties (some of which are significant or beyond the Company’s control) and assumptions that could cause actual results to differ materially from the Company’s historical experience and the Company’s present expectations or projections. You should carefully consider the foregoing factors and the other risks and uncertainties that affect the parties’ businesses, including those described in the Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other documents filed from time to time by the Company and Topco with the United States Securities and Exchange Commission (the “SEC”) and those described in Technip’s annual reports, registration documents and other documents filed from time to time with the French financial markets regulator (Autorité des Marchés Financiers or the “AMF”). The Company wishes to caution you not to place undue reliance on any forward-looking statements, which speak only as of the date hereof. The Company undertakes no obligation to publicly update or revise any forward-looking statements after the date they are made, whether as a result of new information, future events or otherwise, except to the extent required by law.

No offer of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act and applicable European regulations. Subject to certain exceptions to be approved by the relevant regulators or certain facts to be ascertained, the public offer will not be made directly or indirectly, in or into any jurisdiction where to do so would constitute a violation of the laws of such jurisdiction, or by use of the mails or by any means or instrumentality (including without limitation, facsimile transmission, telephone and the internet) of interstate or foreign commerce, or any facility of a national securities exchange, of any such jurisdiction.
