To Foster Wheeler Employees:

I am writing you today to provide an update on our pending acquisition by AMEC plc.

As you know, there has been little news or official public comment from Foster Wheeler or AMEC about the deal since our February 13 announcements. It is customary for companies like ours to be largely silent during this interim period, in part, because transactions such as this are subject to strict disclosure guidelines.

That said, I can assure you that both companies are doing a tremendous amount of work to move this process forward. Teams of AMEC and Foster Wheeler people are working to develop integration plans for the new organization. Specifically, Roberto Penno and Gary Nedelka, our CEOs of the Global E&C Group and the Global Power Group, respectively, are serving with AMEC executives on an integration steering committee that will oversee the integration of the two organizations. In addition, AMEC and Foster Wheeler are fully engaged in collaborative efforts to obtain, among other things, the various regulatory and shareholder approvals that are required in order to complete the transaction.

We are making very good progress. For example, the U.S. Federal Trade Commission has already granted early approval under the Hart-Scott-Rodino Act with respect to the deal. And while there is still a sizable amount of work to be done on all fronts, we expect that the transaction will close in the third quarter of 2014.

So that you are all aware of the amount of work that is going on “behind the scenes” on the deal, I have listed below a few of the most important steps in the process.

As I have said previously, I believe the combination of AMEC and Foster Wheeler is positive for our employees. In particular, the combined company will provide enhanced opportunities to work across a broader range of projects, geographies and markets.

I also believe the transaction is good news for clients; we have spoken to numerous clients, and the feedback has been positive. And on that note in particular, I want to thank you for your continued commitment to serving our clients during – and beyond – this transition period.

I will offer additional updates as the transaction progresses.

Sincerely

Kent Masters

Chief Executive Officer

Foster Wheeler AG communication materials may contain forward-looking statements that are based on management’s assumptions, expectations and projections about the Company and the various industries within which the Company operates. These include statements regarding the Company’s expectations about revenues (including as expressed by its backlog), its liquidity, the outcome of litigation and legal proceedings and recoveries from customers for claims and the costs of current and future asbestos claims and the amount and timing of related insurance recoveries. Such forward-looking statements by their nature involve a degree of risk and uncertainty. The Company cautions that a variety of factors, including but not limited to the factors described in the Form 10-K for the year ended December 31, 2013, filed with the SEC on February 27, 2014, and the following, could cause the Company’s business conditions and results to differ materially from what is contained in forward-looking statements including: the timing and success of the proposed offer and acquisition of the Company by AMEC, the risk that the Company’s business will be adversely impacted during the pending proposed offer and acquisition of the Company by AMEC, benefits, effects or results of the Company’s redomestication to Switzerland, deterioration in global economic conditions, changes in investment by the oil and gas, oil refining, chemical/petrochemical and power generation industries, changes in the financial condition of its customers, changes in regulatory environments, changes in project design or schedules, contract cancellations, the changes in estimates made by the Company of costs to complete projects, changes in trade, monetary and fiscal policies worldwide, compliance with laws and regulations relating to the Company’s global operations, currency fluctuations, war, terrorist attacks and/or natural disasters affecting facilities either owned by the Company or where equipment or services are or may be provided by the Company, interruptions to shipping lanes or other methods of transit, outcomes of pending and future litigation, including litigation regarding the Company’s liability for damages and insurance coverage for asbestos exposure, protection and validity of the Company’s patents and other intellectual property rights, increasing global competition, compliance with its debt covenants, recoverability of claims against the Company’s customers and others by the Company and claims by third parties against the Company, and changes in estimates used in its critical accounting policies. Other factors and assumptions not identified above were also involved in the formation of these forward-looking statements and the failure of such other assumptions to be realized, as well as other factors, may also cause actual results to differ materially from those projected. Most of these factors are difficult to predict accurately and are generally beyond the Company’s control. You should consider the areas of risk described above in connection with any forward-looking statements that may be made by the Company. The Company undertakes no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise. You are advised, however, to consult any additional disclosures the Company makes in proxy statements, quarterly reports on Form 10-Q, annual reports on Form 10-K and current reports on Form 8-K filed with or furnished to the SEC.
