Quanta completed the acquisition of InfraSource Services through an all-stock merger and so the reported results of operations include the results of InfraSource for September 2007 and are compared to the pre-merger historical results of Quanta for prior fiscal periods.

For the third quarter of 2007, income from continuing operations was $47 million, or $0.30 per diluted share, compared to income from continuing operations of $22.3 million, or $0.17 per diluted share, for the third quarter of 2006.

John Colson, chairman and CEO OF Quanta, said: The third quarter was historic for Quanta as we completed the InfraSource acquisition and began the integration process. Financial and operating results continue to be strong, assisted by a partial quarter contribution from InfraSource.
