Nov 2 (Reuters) - Construction and engineering company Emcor Group Inc (EME.N) posted lower-than-expected quarterly results hurt by lower sales and higher restructuring expenses, but raised its full-year adjusted earnings outlook.
The company, which makes systems for power generation and distribution, voice and data communications and heating, ventilation and air-conditioning (HVAC), now sees full-year adjusted earnings of $1.78-$1.90 a share, up from its prior view of $1.60-$1.85 a share.
For the third quarter, the company reported a loss of $175.6 million, or $2.64 a share, compared with a profit of $40 million, or 59 cents a share a year ago.
Excluding a non-cash impairment charge, the company which competes with Comfort Systems USA Inc (FIX.N), Integrated Electrical Services Inc (IESC.O) and Johnson Controls Inc (JCI.N), earned 45 cents a share.
Revenue fell 7 percent to $1.27 billion. Restructuring expenses rose 19 times to $1.7 million.
Analysts on average had expected earnings of 50 cents a share, before special items, on revenue of $1.3 billion, according to Thomson Reuters I/B/E/S.
Shares of the Norwalk, Connecticut-based company closed at $25.65 on Monday on the New York Stock Exchange. They have gained about 10 percent in value since Aug. 16, when Breeden Capital Management said it acquired a stake in the company.
