In the first and second quarters of 2012, Quanta acquired four businesses, which included one electric power infrastructure services company based in Canada, two electric power infrastructure services companies based in the United States and one natural gas and pipeline infrastructure services company based in the United States. These businesses have been reflected in Quanta’s consolidated financial statements as of their respective acquisition dates. The aggregate consideration for these acquisitions consisted of approximately $57.5 million in cash, 1,927,113 shares of Quanta common stock valued at approximately $37.3 million and the repayment of $11.0 million in debt. These acquisitions allow Quanta to expand its capabilities and scope of services internationally and in the United States. The financial results of these businesses are generally included in the corresponding segment.

2011 Acquisitions

In the third and fourth quarters of 2011, Quanta acquired five businesses, which included three electric power infrastructure services companies based in Canada, one electric power infrastructure services company based in the United States and one natural gas and pipeline infrastructure services company based in Australia. These businesses have been reflected in Quanta’s consolidated financial statements as of their respective acquisition dates. The aggregate consideration for these acquisitions consisted of approximately $80.8 million in cash, 1,939,813 shares of Quanta common stock valued at approximately $32.4 million and the repayment of $3.4 million in debt. These acquisitions allow Quanta to further expand its capabilities and scope of services internationally and in the United States. The financial results of these businesses are generally included in the corresponding segment.

2010 Acquisition

On October 25, 2010, Quanta acquired Valard. In connection with the acquisition, Quanta paid the former owners of Valard approximately $118.9 million in cash and issued 623,720 shares of Quanta common stock and 3,909,110 exchangeable shares of a Canadian subsidiary of Quanta. In addition, Quanta issued one share of Quanta Series F preferred stock to a voting trust on behalf of the holders of the exchangeable shares. The Series F preferred stock provides the holders of exchangeable shares with voting rights in Quanta common stock equivalent to the number of exchangeable shares outstanding at any time. The aggregate value of the common stock and exchangeable shares issued was approximately $83.4 million. The exchangeable shares are substantially equivalent to, and exchangeable on a one-for-one basis for, Quanta common stock. As part of the consideration paid for Valard, Quanta also repaid $12.8 million in Valard debt at the closing of the acquisition. As this transaction was effective October 25, 2010, the results of Valard have been included in the consolidated financial statements beginning on such date. This acquisition allows Quanta to further expand its capabilities and scope of services in Canada. Valard’s financial results are generally included in Quanta’s Electric Power Infrastructure Services segment.

The following table summarizes the aggregate consideration paid for the 2012 and 2011 acquisitions and presents the allocation of these amounts to the net tangible and identifiable intangible assets based on their estimated fair values as of the respective acquisition dates. This allocation requires the significant use of estimates and is based on information that was available to management at the time these consolidated financial statements were prepared (in thousands).

The fair value of current assets acquired in 2012 includes accounts receivable with a fair value of $15.3 million. The fair value of current assets acquired in 2011 included accounts receivable with a fair value of $16.1 million.

Goodwill represents the excess of the purchase price over the net amount of the fair values assigned to assets acquired and liabilities assumed. The 2012, 2011 and 2010 acquisitions strategically expanded Quanta’s Canadian service offering, added an Australian service offering and enhanced its domestic electric power and natural gas and oil pipeline service offerings, which Quanta believes contributes to the recognition of the goodwill. In connection with the 2012 acquisitions, goodwill of $57.5 million was recorded for reporting units included within Quanta’s electric power division and $7.3 million was recorded for the reporting unit included within Quanta’s natural gas and pipeline division at December 31, 2012. In connection with the 2011 acquisitions, goodwill of $34.9 million was recorded for reporting units included within Quanta’s electric power division and $8.9 million was recorded for the reporting unit included within Quanta’s natural gas and pipeline division at December 31, 2011. Goodwill of approximately $52.9 million and $13.1 million is expected to be deductible for income tax purposes related to the businesses acquired in 2012 and 2011.

The unaudited supplemental pro forma results of operations have been provided for illustrative purposes only and do not purport to be indicative of the actual results that would have been achieved by the combined companies for the periods presented or that may be achieved by the combined companies in the future. Future results may vary significantly from the results reflected in the following pro forma financial information because of future events and transactions, as well as other factors (in thousands, except per share amounts):

The pro forma combined results of operations for the years ended December 31, 2012 and 2011 have been prepared by adjusting the historical results of Quanta to include the historical results of the 2012 acquisitions as if they occurred January 1, 2011. The pro forma combined results of operations for the year ended December 31, 2011 have also been prepared by adjusting the historical results of Quanta to include the historical results of the 2011 acquisitions as if they occurred January 1, 2010. The pro forma combined results of operations for the year ended December 31, 2010 have been prepared by adjusting the historical results of Quanta to include the historical results of the 2011 acquisitions as if they occurred January 1, 2010 and the historical results of the 2010 acquisition as if it occurred January 1, 2009. These pro forma combined historical results were then adjusted for the following: a reduction of interest expense and interest income as a result of the repayment of outstanding indebtedness, a reduction of interest income as a result of the cash consideration paid, an increase in amortization expense due to the incremental intangible assets recorded related to the 2012, 2011 and 2010 acquisitions, an increase or decrease in depreciation expense within cost of services related to the net impact of adjusting acquired property and equipment to the acquisition date fair value and conforming depreciable lives with Quanta’s accounting policies, an increase in the number of outstanding shares of Quanta common stock and certain reclassifications to conform the acquired companies’ presentation to Quanta’s accounting policies. The pro forma results of operations do not include any adjustments to eliminate the impact of acquisition related costs or any cost savings or other synergies that may result from the 2012, 2011 and 2010 acquisitions. As noted above, the pro forma results of operations do not purport to be indicative of the actual results that would have been achieved by the combined company for the periods presented or that may be achieved by the combined company in the future.
