Shares of engineering and construction companies Fluor (FLR) and Jacobs Engineering Group (JEC) are falling after one of their competitors, KBR (KBR), lowered its fiscal 2012 earnings per share guidance. KBR now expects its fiscal 2012 EPS to be $1.95-$2.10 excluding a goodwill charge for the third quarter, down from its previous forecast of $2.60-$2.80. The company also forecast that its fiscal 2013 EPS will be $2.45-$2.90, below analysts' consensus estimate of $2.96. KBR blamed the reduction in its 2012 guidance on project charges it expects to take for its Minerals and U.S. Construction businesses, along with higher than expected labor costs. The company expects its business to strengthen in the second half of 2013 as existing projects continue to advance. In mid-morning trading, Fluor dropped 1.44% to $61.73, Jacobs Engineering slid 1.15% to $44.67, and KBR tumbled 8.13% to $29.40.
