Foster Wheeler Provides Updated Earnings Guidance and Summary of 2013 Share Repurchase Activity

Foster Wheeler AG (Nasdaq: FWLT) announced today that it expects its 2013 full-year financial results to be unfavorably affected by two factors that, in aggregate, will likely impact the full-year diluted earnings per share by approximately $0.11. This impact will be reflected in the company’s first-quarter 2013 diluted earnings per share, which are expected to be approximately $0.12, or $0.14 on an adjusted basis excluding asbestos-related provisions, which are expected to be $0.02 per diluted share.

The items are 1) mark-to-market losses on currency transactions amounting to approximately $0.07 per diluted share, and 2) an additional non-cash impairment charge relating to the Camden, New Jersey, waste-to-energy facility amounting to about $0.04 per diluted share.

The losses on currency transactions resulting from mark-to-market adjustments are due principally to the decline in the value of the British pound in relation to the US dollar as of the close of the first quarter of 2013. The estimates of such impacts on 2013 financial results are based on currency exchange rates in effect at the end of March 2013; future changes in exchange rates could affect the company’s financial results.

As a result of these unfavorable items, Foster Wheeler now expects its 2013 adjusted diluted earnings per share to be flat to moderately below the company’s 2012 adjusted diluted earnings per share of $1.54 (as detailed in the table below).

The company reaffirmed its previous full-year guidance regarding scope revenues, EBITDA margins on scope revenues and EBITDA for its two business groups. That guidance was issued on March 1, 2013.

The company has invested $100 million to purchase its shares from January 2013 through April 2013.

The company plans to report its financial results for the first quarter of 2013 on May 2.
