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 our 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 our current expectations, beliefs and assumptions concerning future developments and business conditions and their potential effect on us. While management believes that these forward-looking statements are reasonable as and when made, there can be no assurance that future developments affecting us will be those that we anticipate.

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 FMC Technologies SIS Limited (to be renamed TechnipFMC plc) (“TechnipFMC”) 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 TechnipFMC 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 of our forward-looking statements involve risks and uncertainties (some of which are significant or beyond our control) and assumptions that could cause actual results to differ materially from our historical experience and our 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 FMC Technologies’ (“FMC Technologies”) 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

FMC Technologies and TechnipFMC with the United States Securities and Exchange Commission (the “SEC”) and those described in Technip S.A.’s (“Technip”) 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”). We wish to caution you not to place undue reliance on any forward-looking statements, which speak only as of the date hereof. We undertake no obligation to publicly update or revise any of our 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.
