HOUSTON, Feb. 22 /PRNewswire-FirstCall/ -- Quanta Services, Inc. today announced results for the three and twelve months ended December 31, 2006.

Revenues in the fourth quarter of 2006 were a record high of $592.0 million, compared to revenues of $523.5 million in the fourth quarter of 2005. After recording a non-cash goodwill impairment charge of $56.6 million, net of tax, or $0.46 per diluted share, the net loss for the fourth quarter of 2006 was $30.5 million, or a loss per diluted share of $0.26, compared to net income of $18.5 million, or earnings per diluted share of $0.15 in the fourth quarter of 2005. For the three months ended December 31, 2006, adjusted net income, excluding the non-cash goodwill impairment charge, was $26.1 million or $0.20 per diluted share.

Revenues for the twelve months of 2006 were a record high of $2.13 billion, compared to $1.86 billion for the twelve months of 2005. For the twelve months of 2006, the company reported net income of $17.5 million, or earnings per diluted share of $0.15, compared to net income of $29.6 million, or earnings per diluted share of $0.25 for twelve months of 2005. For the twelve months ended December 31, 2006, adjusted net income, excluding the non- cash goodwill impairment charge, was $74.1 million or $0.58 per diluted share. The adjusted net income and earnings per diluted share for the fourth quarter and full year 2006 are non-GAAP measures.

"This was a year of strength for Quanta. For 2006, we achieved internal revenue growth of 15 percent, increased operating income by 94 percent excluding the goodwill impairment charge, and reached record backlog for the third consecutive quarter," said John Colson, chairman and chief executive officer of Quanta Services. "This signifies the high demand for our services as the industries we serve focus on enhancing and expanding infrastructure to meet the growing demand for power and telecommunications services."

The non-cash goodwill impairment charge recorded in the fourth quarter of 2006 was associated with one of the company's operating units that has historically served the cable TV industry. This charge is a result of the annual impairment evaluation of the company's goodwill balances as required by SFAS No. 142, "Goodwill and Other Intangible Assets."

The non-GAAP measures in this press release are provided to enable investors to evaluate quarterly and annual performance excluding the effects of the non-cash goodwill impairment charge that management believes impact the comparability of operating results between reporting periods.

RECENT HIGHLIGHTS - -- Renewed Electric Utility Contract - Quanta has obtained the renewal of a three-year contract valued at $80 million to $100 million per year, with an option for a two-year extension. Under the contract, Quanta will provide transmission and distribution new construction and maintenance services for the Pacific Northwest utility. -- Supported Utilities in Restoration Efforts - In late 2006 and early 2007, Quanta deployed workers to support efforts to restore power following wind and ice storms. These storms were most extreme in the Northwest and Central United States. In some areas of Nebraska, more than four inches of ice accumulated on power lines during the storms. -- Secured Contracts with NPPD to Rebuild Infrastructure - Nebraska Public Power District (NPPD) has recently contracted with Quanta to rebuild eight sections of transmission line, totaling 172 miles, including the rebuilding or replacement of more than 600 structures. The transmission infrastructure was damaged by recent ice storms and is critical to the reliability and stability of NPPD's power delivery system. The majority of the work is expected to be completed before the 2007 summer peak load. -- Expanded Service Offering Through Acquisition - In January 2007, Quanta completed the acquisition of Clearfield, Iowa-based Longfellow Drilling, Inc. (LDI). LDI is a specialized contractor in the installation of drilled pier foundations for a diversified customer base throughout the United States. The acquisition enhances Quanta's in-house capabilities to install drilled pier foundations for electric transmission towers and wireless telecommunication towers. OUTLOOK
