1.	BUSINESS AND ORGANIZATION:

Quanta Services, Inc. (Quanta) is a leading national provider of specialized contracting services. Beginning January 1, 2008, Quanta began reporting its results under two business segments. The infrastructure services (Infrastructure Services) segment provides specialized contracting services, offering end-to-end network solutions to the electric power, gas, telecommunications and cable television industries, including the design, installation, repair and maintenance of network infrastructure, as well as certain ancillary services. Additionally, the dark fiber construction and leasing (Dark Fiber) segment, which was acquired on August 30, 2007 in the Merger as described below, leases point-to-point fiber-optic telecommunications infrastructure in select markets and provides related design, procurement, construction and maintenance services. Prior to January 1, 2008, Quanta reported results under one business segment, which consisted primarily of the services now under the Infrastructure Services segment.

On August 30, 2007, Quanta acquired, through a merger transaction (the Merger), all of the outstanding common stock of InfraSource Services, Inc. (InfraSource). For accounting purposes, the transaction was effective as of August 31, 2007, and results of InfraSource’s operations have been included in the consolidated financial statements subsequent to August 31, 2007. Accordingly, the first quarter of 2007 does not include any results from InfraSource. Similar to Quanta, InfraSource provided specialized infrastructure contracting services to the electric power, gas and telecommunications industries primarily in the United States. The acquisition enhanced and expanded Quanta’s capabilities in its existing service areas and added the Dark Fiber segment.

On August 31, 2007, Quanta sold the operating assets associated with the business of Environmental Professional Associates, Limited (EPA), a Quanta subsidiary. Accordingly, Quanta has presented EPA’s results of operations for the first quarter of 2007 as a discontinued operation in the accompanying consolidated statements of operations.

Interim Condensed Consolidated Financial Information

These unaudited condensed consolidated financial statements have been prepared pursuant to the rules of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States, have been condensed or omitted pursuant to those rules and regulations. Quanta believes that the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations and cash flows with respect to the interim consolidated financial statements have been included. The results of operations for the interim periods are not necessarily indicative of the results for the entire fiscal year. The results of Quanta historically have been subject to significant seasonal fluctuations.

Quanta recommends that these unaudited condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and notes thereto of Quanta and its subsidiaries included in Quanta’s Annual Report onForm 10-K for the year ended December 31, 2007, which was filed with the SEC on February 29, 2008.

Use of Estimates and Assumptions

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities known to exist as of the date the financial statements are published and the reported amount of revenues and expenses recognized during the periods presented. Quanta reviews all significant estimates affecting its consolidated financial statements on a recurring basis and records the effect of any necessary adjustments prior to their publication. Judgments and estimates are

QUANTA SERVICES INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

based on Quanta’s beliefs and assumptions derived from information available at the time such judgments and estimates are made. Uncertainties with respect to such estimates and assumptions are inherent in the preparation of financial statements. Estimates are primarily used in Quanta’s assessment of the allowance for doubtful accounts, valuation of inventory, useful lives of property and equipment, fair value assumptions in analyzing goodwill, other intangibles and long-lived asset impairments, self-insured claims liabilities, revenue recognition under percentage-of-completion accounting and for dark fiber leasing, share-based compensation, provision for income taxes and purchase price allocations.

Reclassifications

Certain reclassifications have been made in prior year’s financial statements to conform to classifications used in the current year.

Short-Term Investments

Quanta held no short-term investments as of December 31, 2007 or March 31, 2008; however during the first quarter of 2007, Quanta invested from time to time in variable rate demand notes (VRDNs), which were classified as short-term investments available for sale. The income from VRDNs was tax-exempt to Quanta.

Accounts Receivable and Allowance for Doubtful Accounts

Quanta provides an allowance for doubtful accounts when collection of an account or note receivable is considered doubtful, and receivables are written off against the allowance when deemed uncollectible. Inherent in the assessment of the allowance for doubtful accounts are certain judgments and estimates including, among others, the customer’s access to capital, the customer’s willingness or ability to pay, general economic conditions and the ongoing relationship with the customer. Under certain circumstances such as foreclosures or negotiated settlements, Quanta may take title to the underlying assets in lieu of cash in settlement of receivables. Material changes in Quanta’s customers’ revenues or cash flows could affect its ability to collect amounts due from them. As of March 31, 2008, Quanta had total allowances for doubtful accounts of approximately $5.7 million. Should customers experience financial difficulties or file for bankruptcy, or should anticipated recoveries relating to receivables in existing bankruptcies or other workout situations fail to materialize, Quanta could experience reduced cash flows and losses in excess of current allowances provided.

The balances billed but not paid by customers pursuant to retainage provisions in certain contracts will be due upon completion of the contracts and acceptance by the customer. Based on Quanta’s experience with similar contracts in recent years, the majority of the retention balances at each balance sheet date will be collected within the subsequent fiscal year. Current retainage balances as of December 31, 2007 and March 31, 2008 were approximately $60.2 million and $62.8 million and are included in accounts receivable. Also included in other assets, net as of December 31, 2007 and as of March 31, 2008 were $2.1 million and $2.8 million in retainage balances with settlement dates beyond the next twelve months.

Within accounts receivable, Quanta recognizes unbilled receivables in circumstances such as when: revenues have been earned and recorded but the amount cannot be billed under the terms of the contract until a later date; costs have been incurred but are yet to be billed under cost-reimbursement type contracts; or amounts arise from routine lags in billing (for example, for work completed one month but not billed until the next month). These balances do not include revenues accrued for work performed under fixed-price contracts as these amounts are recorded as costs and estimated earnings in excess of billings on uncompleted contracts. At December 31, 2007 and March 31, 2008, the balances of unbilled receivables included in accounts receivable were approximately $132.3 million and $171.0 million.

As of December 31, 2007, other assets, net included accounts and notes receivable due from a customer relating to the construction of independent power plants. During 2006, the underlying assets which had secured

QUANTA SERVICES INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

these notes receivable were sold pursuant to liquidation proceedings and the net proceeds were being held by a trustee. Quanta recorded allowances for a significant portion of these notes receivable in prior periods. As of December 31, 2007, the collection of amounts owed Quanta were subject to further legal proceedings; however, in March 2008, the parties reached a settlement resulting in the payment of the net receivable amount and the release of any future claims against Quanta. The remaining note receivable balance was written off against the related allowance of approximately $43.0 million in March 2008, without any impact to Quanta’s results of operations for the first quarter of 2008.

Income Taxes

Quanta follows the liability method of accounting for income taxes in accordance with Statement of Financial Accounting Standards (SFAS) No. 109, “Accounting for Income Taxes.” Under this method, deferred tax assets and liabilities are recorded for future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and are measured using the enacted tax rates and laws that are expected to be in effect when the underlying assets or liabilities are recovered or settled.

Quanta regularly evaluates valuation allowances established for deferred tax assets for which future realization is uncertain. The estimation of required valuation allowances includes estimates of future taxable income. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Quanta considers projected future taxable income and tax planning strategies in making this assessment. If actual future taxable income differs from these estimates, Quanta may not realize deferred tax assets to the extent estimated.

Quanta accounts for uncertain tax positions in accordance with FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — An Interpretation of SFAS No. 109, Accounting for Income Taxes” (FIN No. 48). FIN No. 48 prescribes a comprehensive model for how companies should recognize, measure, present and disclose in their financial statements uncertain tax positions taken or to be taken on a tax return.

As of March 31, 2008, the total amount of unrecognized tax benefits relating to uncertain tax positions was $51.8 million, an increase from December 31, 2007 of $2.5 million related to tax positions expected to be taken in 2008. For the quarter ended March 31, 2008, Quanta recognized $1.3 million of interest and penalties in the provision for income taxes. During the three months ended March 31, 2007, Quanta recorded $15.3 million in tax benefits primarily due to a decrease in reserves for uncertain tax positions resulting from the settlement of a multi-year Internal Revenue Service audit.

The income tax laws and regulations are voluminous and are often ambiguous. As such, Quanta is required to make many subjective assumptions and judgments regarding its tax positions that could materially affect amounts recognized in its future consolidated balance sheets and statements of income.

Revenue Recognition

Infrastructure Services — Quanta designs, installs and maintains networks for the electric power, gas, telecommunications and cable television industries, as well as provides various ancillary services to commercial, industrial and governmental entities. These services may be provided pursuant to master service agreements, repair and maintenance contracts and fixed price and non-fixed price installation contracts. Pricing under these contracts may be competitive unit price, cost-plus/hourly (or time and materials basis) or fixed price (or lump sum basis), and the final terms and prices of these contracts are frequently negotiated with the customer. Under unit-based contracts, the utilization of an output-based measurement is appropriate for revenue recognition. Under these contracts, Quanta recognizes revenue when units are completed based on pricing established between Quanta and the customer for each unit of delivery, which best reflects the pattern in which the obligation to the customer is fulfilled. Under cost-plus/hourly and time and materials type contracts, Quanta recognizes revenue on an input-basis, as labor hours are incurred and services are performed.

QUANTA SERVICES INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Revenues from fixed price contracts are recognized using the percentage-of-completion method, measured by the percentage of costs incurred to date to total estimated costs for each contract. These contracts provide for a fixed amount of revenues for the entire project. Such contracts provide that the customer accept completion of progress to date and compensate us for services rendered, measured in terms of units installed, hours expended or some other measure of progress. Contract costs include all direct material, labor and subcontract costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation costs. Much of the materials associated with Quanta’s work are owner-furnished and are therefore not included in contract revenues and costs. The cost estimation process is based on the professional knowledge and experience of Quanta’s engineers, project managers and financial professionals. Changes in job performance, job conditions and final contract settlements are factors that influence management’s assessment of the total estimated costs to complete those contracts and therefore, Quanta’s profit recognition. Changes in these factors may result in revisions to costs and income, and their effects are recognized in the period in which the revisions are determined. Provisions for the total estimated losses on uncompleted contracts are made in the period in which such losses are determined.

Quanta may incur costs subject to change orders, whether approved or unapproved by the customer,and/or claims related to certain contracts. Quanta determines whether there is a probability that the costs will be recovered based upon evidence such as past practices with the customer, specific discussions or preliminary negotiations with the customer or verbal approvals. Quanta treats items as a cost of contract performance in the period incurred if it is not probable that the costs will be recovered, or will recognize revenue if it is probable that the contract price will be adjusted and can be reliably estimated.

The current asset “Costs and estimated earnings in excess of billings on uncompleted contracts” represents revenues recognized in excess of amounts billed for fixed price contracts. The current liability “Billings in excess of costs and estimated earnings on uncompleted contracts” represents billings in excess of revenues recognized for fixed price contracts.

Dark Fiber — Quanta has fiber-optic facility licensing agreements with various customers, pursuant to which it recognizes revenues, including any initial fees or advanced billings, ratably over the expected length of the agreements, including probable renewal periods. As of December 31, 2007 and March 31, 2008, initial fees and advanced billings on these licensing agreements not yet recorded in revenue were $23.2 million and $22.8 million and are recognized as deferred revenue, with $15.6 million and $15.2 million considered to be long-term and included in other non-current liabilities.

Stock-Based Compensation

Effective January 1, 2006, Quanta adopted SFAS No. 123 (revised 2004), “Share-Based Payment” (SFAS No. 123(R)), using the modified prospective method of adoption, which requires recognition of compensation expense for all stock-based compensation beginning on the effective date. Under this method of accounting, compensation cost for stock-based compensation awards is based on the fair value of the awards granted, net of estimated forfeitures, at the date of grant. Quanta values share-based awards using the Black-Scholes option pricing model. Forfeitures are estimated using historical activity. The resulting compensation costs are recognized on a straight-line basis over the service period of each award. SFAS No. 123(R) requires the cash flows resulting from the tax deductions in excess of the compensation cost recognized for those options (excess tax benefit) to be classified as financing cash flows.

New Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” SFAS No. 157 defines fair value, establishes methods used to measure fair value and expands disclosure requirements about fair value measurements. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal periods, as it relates to financial assets and liabilities, as well as for any non-financial assets and liabilities that are carried at fair value. SFAS No. 157 also requires certain tabular disclosure related to results of applying SFAS No. 144, “Accounting for Impairment or Disposal of Long-Lived Assets” and SFAS No. 142, “Goodwill and Other Intangible Assets.” On November 14, 2007, the FASB provided a one year deferral for the implementation of SFAS No. 157 for non-financial assets and liabilities. SFAS No. 157 excludes from its scope SFAS No. 123(R) and its related interpretive accounting pronouncements that address share-based payment transactions. Quanta adopted SFAS No. 157 on January 1, 2008 as it applies to its financial assets and liabilities, and based on the November 14, 2007 deferral of SFAS No. 157 for non-financial assets and liabilities, Quanta will begin following the guidance of SFAS No. 157 with respect to its non-financial assets and liabilities in the quarter ended March 31, 2009. Quanta does not currently have any material financial assets and liabilities recognized on its balance sheet that are impacted by the partial adoption of SFAS No. 157. Additionally, Quanta does not currently have any material non-financial assets or liabilities that are carried at fair value on a recurring basis; however, Quanta does have non-financial assets that are evaluated against measures of fair value on a recurring or as needed basis, including goodwill, other intangibles and long-term assets held and used. Based on the financial and non-financial assets and liabilities on its balance sheet as of March 31, 2008, Quanta does not expect the adoption of SFAS No. 157 to have a material impact on its consolidated financial position, results of operations or cash flows.

QUANTA SERVICES INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

On January 1, 2008, Quanta adopted SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities, including an amendment of FASB No. 115.” SFAS No. 159 permits entities to choose to measure at fair value many financial instruments and certain other items that were not previously required to be measured at fair value. Unrealized gains and losses on items for which the fair value option has been elected are reported in earnings. SFAS No. 159 does not affect any existing accounting literature that requires certain assets and liabilities to be carried at fair value. The adoption of SFAS No. 159 did not have any material impact on Quanta’s consolidated financial position, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements — an amendment of ARB No. 51.” SFAS No. 160 addresses the accounting and reporting framework for minority interests by a parent company. SFAS No. 160 is to be effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. Accordingly, Quanta will adopt SFAS No. 160 in the first quarter of fiscal year 2009. Because Quanta does not currently have any subsidiaries with noncontrolling interests, the adoption of SFAS No. 160 is not anticipated to have a material impact on its consolidated financial position, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 141(R), “Business Combinations.” SFAS No. 141(R) is effective for fiscal years beginning after December 15, 2008. Earlier application is prohibited. Assets and liabilities that arose from business combinations occurring prior to the adoption of SFAS No. 141(R) cannot be adjusted upon the adoption of SFAS No. 141(R). SFAS No. 141(R) requires the acquiring entity in a business combination to recognize all (and only) the assets acquired and liabilities assumed in the business combination; establishes the acquisition date as the measurement date to determine the fair value for all assets acquired and liabilities assumed; and requires the acquirer to disclose to investors and other users all of the information needed to evaluate and understand the nature and financial effect of the business combination. As it relates to recognizing all (and only) the assets acquired and liabilities assumed in a business combination, costs an acquirer expects but is not obligated to incur in the future to exit an activity of an acquiree or to terminate or relocate an acquiree’s employees are not liabilities at the acquisition date but must be expensed in accordance with other applicable generally accepted accounting principles. If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the acquirer must report in its financial statements provisional amounts for the items for which the accounting is incomplete. During the measurement period, which must not exceed one year from the acquisition date the acquirer will retrospectively adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. The acquirer will be required to expense all acquisition-related costs in the periods such costs are incurred other than costs to issue debt or equity securities in connection with the acquisition. SFAS No. 141(R) will not have an impact on Quanta’s consolidated financial position, results of operations or cash flows at the date of adoption, but it could have a material impact on its consolidated financial position, results of operations or cash flows in future periods when it is applied to acquisitions that occur in 2009 and beyond.

On January 1, 2008, Quanta adopted EITF IssueNo. 06-11, “Accounting for Income Tax Benefits of Dividends on Share-Based Payment Awards.”EITF 06-11 requires that a realized income tax benefit from dividends or dividend equivalent units paid on unvested restricted shares and restricted share units be reflected as an increase in contributed surplus and reflected as an addition to the company’s excess tax benefit pool, as defined under SFAS No. 123(R). Because Quanta did not declare any dividends during the first quarter of 2008 and does not currently anticipate declaring dividends in the near future,EITF 06-11 did not have any impact during the first quarter of 2008, and is not expected to have a material impact in the near term, on Quanta’s consolidated financial position, results of operations or cash flows.

In December 2007, the SEC published Staff Accounting Bulletin No. 110 (SAB 110). SAB 110 expresses the views of the SEC staff regarding the use of a “simplified” method, as discussed in SAB No. 107 (SAB 107), in developing an estimate of the expected term of “plain vanilla” share options in accordance with SFAS No. 123(R).

QUANTA SERVICES INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

In particular, the SEC staff indicated in SAB 107 that it will accept a company’s election to use the simplified method, regardless of whether the company has sufficient information to make more refined estimates of the expected term. However, the SEC staff stated in SAB 107 that it would not expect a company to use the simplified method for share option grants after December 31, 2007. In SAB 110, the SEC staff states that they would continue to accept, under certain circumstances, the use of the simplified method beyond December 31, 2007. Because Quanta currently does not anticipate issuing stock options in the near future, SAB 110 is not anticipated to have a material impact on its consolidated financial position, results of operations or cash flows in the near term.

In March 2008, the FASB issued SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities — An Amendment of FASB No. 133.” SFAS No. 161 requires enhanced disclosures to enable investors to better understand how a reporting entity’s derivative instruments and hedging activities impact the entity’s financial position, financial performance and cash flows. SFAS No. 161 is effective for financial statements issued after November 15, 2008, including interim financial statements. Early application is encouraged. Since Quanta does not currently have any derivatives or hedging activities, SFAS No. 161 is not anticipated to have a material impact on Quanta’s consolidated financial position, results of operations, cash flows or disclosures.

2. INFRASOURCE ACQUISITION:

On August 30, 2007, Quanta acquired through the Merger all of the outstanding common stock of InfraSource. In connection with the acquisition, Quanta issued to InfraSource’s stockholders 1.223 shares of Quanta common stock for each outstanding share of InfraSource common stock, resulting in the issuance of a total of 49,975,553 shares of common stock for an aggregate purchase price of approximately $1.3 billion.

The following summarizes the allocation of the purchase price and estimated transaction costs related to the InfraSource acquisition. This allocation is based on the significant use of estimates and on information that was available to management at the time these condensed consolidated financial statements were prepared. Portions of the allocation of purchase price are preliminary. Accordingly, the allocation will change as management continues to assess available information, and the impact of such changes may be material. Specifically, the valuation of the operating unit engaged in the construction and leasing of fiber-optic telecommunications facilities and the associated customer leases, as well as the values for intangible assets and deferred and other taxes are preliminary and subject to material change based on the results of the final evaluation.

The following table summarizes the estimated fair values (in thousands):


	August 31,
	2007

Current assets	$	287,763
Non-current assets		8,501
Property and equipment		208,754
Intangible assets		158,840
Goodwill		977,820

Total assets acquired		1,641,678

Current liabilities		200,320
Long-term liabilities		169,784

Total liabilities assumed		370,104

Net assets acquired	$	1,271,574

Additionally, Quanta incurred approximately $12.1 million of costs related to the Merger which have been included in goodwill but are not in the above purchase price allocation.

QUANTA SERVICES INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Although they are subject to change based on final evaluations, the preliminary amounts assigned to various intangible assets at August 31, 2007 related to the InfraSource acquisition are customer relationships of $95.3 million, backlog of $50.5 million and non-compete agreements of $13.0 million. The customer relationships are being amortized on a straight-line basis over 15 years, backlog is being amortized based on the estimated pattern of the consumption of the economic benefit over the original weighted average period of 1.3 years and the non-compete agreements are being amortized on a straight-line basis over the lives of the underlying contracts over the original weighted average period of 2.0 years.

Goodwill represents the excess of the purchase price over the fair value of the acquired net assets. Quanta anticipates to continue to realize meaningful operational and cost synergies, such as enhancing the combined service offerings, expanding the geographic reach and resource base of the combined company, improving the utilization of personnel and fixed assets, eliminating duplicate corporate functions, as well as accelerating revenue growth through enhanced cross-selling and marketing opportunities. Quanta believes these opportunities contribute to the recognition of the substantial goodwill.

The following 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 company for the periods presented or that may be achieved by the combined company 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. The following pro forma results of operations have been provided for the quarter ended March 31, 2007 as though the Merger had been completed as of January 1, 2007 (in thousands except per share amounts).


	Three Months
	Ended March 31,
	2007

Revenues	$	772,763
Gross profit	$	106,609
Selling, general and administrative expenses	$	78,590

Income from continuing operations	$	22,634
Net income	$	22,954
Earnings per share from continuing operations:
Basic	$	0.14
Fully diluted	$	0.13

The pro forma combined results of operations have been prepared by adjusting the historical results of Quanta to include the historical results of InfraSource, the reduction in interest expense and interest income as a result of the repayment of InfraSource’s outstanding indebtedness on the acquisition date, certain reclassifications to conform InfraSource’s presentation to Quanta’s accounting policies and the impact of the preliminary purchase price allocation discussed above. The pro forma results of operations do not include any cost savings that may result from the Merger or any estimated costs that have been or will be incurred by Quanta to integrate the businesses. 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. For example, Quanta recorded tax benefits in the first quarter of 2007 of $15.3 million primarily due to a decrease in reserves for uncertain tax positions. Additionally, InfraSource incurred $3.6 million of merger-related costs in the three months ended March 31, 2007 that have not been eliminated in the pro forma results of operations above. Items such as these, coupled with other risk factors that could have affected the combined company and its operations, make it difficult to use the pro forma results of operations to project future results of operations.

4.	DISCONTINUED OPERATION:

On August 31, 2007, Quanta sold the operating assets associated with the business of Environmental Professional Associates, Limited (EPA), a Quanta subsidiary, for approximately $6.0 million in cash. Quanta has presented EPA’s results of operations for the three months ended March 31, 2007 as a discontinued operation in the accompanying condensed consolidated statements of operations. Quanta does not allocate corporate debt or interest expense to discontinued operations.

The amounts of revenues and pre-tax income related to EPA and included in income from discontinued operation are as follows (in thousands):

The assets, liabilities and cash flows associated with EPA have historically been immaterial to Quanta’s balance sheet and cash flows.


5.	STOCK-BASED COMPENSATION:

Stock Incentive Plans

Pursuant to the Quanta Services, Inc. 2007 Stock Incentive Plan (the 2007 Plan), which was adopted on May 24, 2007, Quanta may award restricted common stock, incentive stock options and non-qualified stock options. The purpose of the 2007 Plan is to provide directors, key employees, officers and certain consultants and advisors with additional performance incentives by increasing their proprietary interest in Quanta. Prior to the adoption of the 2007 Plan, Quanta had issued awards of restricted common stock and stock options under its 2001 Stock Incentive Plan (as amended and restated March 13, 2003) (the 2001 Plan), which was terminated effective May 24, 2007, except that outstanding awards will continue to be governed by the terms of the 2001 Plan. The 2007 Plan and the 2001 Plan are referred to as the Quanta Plans.

In connection with the Merger, Quanta assumed InfraSource’s 2003 Omnibus Stock Incentive Plan and 2004 Omnibus Stock Incentive Plan, in each case as amended (the InfraSource Plans). Outstanding awards of InfraSource stock options were converted to options to acquire Quanta common stock, and outstanding awards of InfraSource restricted common stock were converted to Quanta restricted common stock, each as described in further detail below. The InfraSource Plans were terminated in connection with the Merger, and no further awards will be made under these plans, although the terms of these plans will govern outstanding awards.

Stock Options

In connection with the Merger, each option to purchase shares of InfraSource common stock granted under the InfraSource Plans that was outstanding on August 30, 2007 was converted into an option to purchase the number of whole shares of Quanta common stock that was equal to the number of shares of InfraSource common stock subject to that option immediately prior to the effective time of the Merger multiplied by 1.223. These options were converted on the same terms and conditions as applied to each such option immediately prior to the Merger. The exercise price for each InfraSource option granted was also adjusted by dividing the exercise price in effect immediately prior to the Merger for each InfraSource option by 1.223. The former InfraSource options generally vest over four years and have a maximum term of ten years; however, some options vested on August 30, 2007 due to change of control provisions in place in certain InfraSource option or management agreements, and there has been and may be additional accelerated vesting if the employment of certain option holders is terminated within a certain period following the Merger.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

In connection with the Merger, Quanta calculated the fair value of the former InfraSource stock options as of August 30, 2007 using the Black-Scholes model. Assumptions used in this model were based on estimates derived from historic estimates of both Quanta and InfraSource. Quanta estimated expected stock price volatility based on the historical volatility of Quanta’s common stock. The risk-free interest rate assumption included in the calculation is based upon observed interest rates appropriate for the expected life of the InfraSource options. The dividend yield assumption is based on Quanta’s intent not to issue a dividend. Quanta used the simplified method to calculate expected term. Forfeitures were estimated based on Quanta’s historical experience. These assumptions remained unchanged at March 31, 2008.


	August 30, 2007

Weighted Average Assumptions:
Expected volatility		40	%
Dividend yield		0	%
Risk-free interest rate		4.13 — 4.20	%
Annual forfeiture rate		8	%
Expected term (in years)		6.25

The aggregate intrinsic value above represents the total pre-tax intrinsic value, based on Quanta’s closing stock price of $23.17 on March 31, 2008, which would have been received by the option holders had all option holders exercised their options as of that date. Former InfraSource options exercised during the three months ended March 31, 2008 had an intrinsic value of $1.1 million, generated $1.5 million of cash proceeds and generated $0.4 million of associated income tax benefit. When stock options are exercised, Quanta has historically issued new shares to the option holders.

As of March 31, 2008, there was approximately $5.0 million of total unrecognized compensation cost related to unvested stock options issued under the InfraSource Plans. That cost is expected to be recognized over a weighted average period of 2.0 years. The total fair value of the stock options issued under the InfraSource Plans that vested during the three months ended March 31, 2008 was $0.2 million.

Restricted Stock

Under the Quanta Plans, Quanta has issued restricted common stock at the fair market value of the common stock as of the date of issuance. The shares of restricted common stock issued are subject to forfeiture, restrictions on transfer and certain other conditions until they vest, which generally occurs over three years in equal annual installments. During the restriction period, the restricted stockholders are entitled to vote and receive dividends on such shares.

In connection with the Merger, each share of restricted common stock issued under the InfraSource Plans that was outstanding on August 30, 2007 was converted into 1.223 restricted shares of Quanta common stock. The shares of restricted common stock issued under the InfraSource Plans remain subject to forfeiture, restrictions on transfer and certain other conditions of the awards until they vest, which generally occurs in equal annual installments over three or four year periods commencing on the first anniversary of the grant date, with certain exceptions. During the restriction period, the restricted stockholders are entitled to vote and receive dividends on such shares. The vesting period for some holders of restricted stock accelerated and the forfeiture and transfer restrictions lapsed when their employment was terminated following the Merger.

During the three months ended March 31, 2007 and 2008, Quanta granted 0.4 million and 0.7 million shares of restricted stock under the Quanta Plans with a weighted average grant price of $25.43 and $23.02. During the three months ended March 31, 2007 and 2008, 0.6 million and 0.5 million shares vested with an approximate fair value at the time of vesting of $12.6 million and $12.6 million.

Forfeited		(10	)	$	22.57

Unvested at March 31, 2008		1,339		$	22.10

As of March 31, 2008, there was approximately $23.7 million of total unrecognized compensation cost related to unvested restricted stock granted to both employees and non-employees. That cost is expected to be recognized over a weighted average period of 2.32 years.

Compensation expense is measured based on the fair value of the restricted stock and is recognized on a straight-line basis over the requisite service period, which is the vesting period. The fair value of the restricted stock is determined based on the number of shares granted and the closing price of Quanta’s common stock on the date of grant. SFAS No. 123(R) requires estimating future forfeitures in determining the period expense, rather than recording forfeitures when they occur as previously permitted. Quanta uses historical data to estimate the forfeiture rate. The estimate of unrecognized compensation cost uses the expected forfeiture rate; however, the estimate may not necessarily represent the value that will ultimately be realized as compensation expense.

Non-Cash Compensation Expense and Related Tax Benefits

The amounts of non-cash compensation expense and related tax benefits, as well as the amount of actual tax benefits related to vested restricted stock and options exercised and Quanta’s and InfraSource’s employee stock purchase plans, both of which have been terminated, are as follows (in thousands):

Basic earnings per share is computed using the weighted average number of common shares outstanding during the period, and diluted earnings per share is computed using the weighted average number of common shares outstanding during the period adjusted for all potentially dilutive common stock equivalents, except in cases where the effect of the common stock equivalent would be antidilutive. The weighted average number of shares used to compute the basic and diluted earnings per share for the three months ended March 31, 2007 and 2008 is illustrated below (in thousands, except per share amounts):

For the three months ended March 31, 2007 and 2008, stock options for approximately 0.1 million and 0.1 million shares, respectively, were excluded from the computation of diluted earnings per share because the options’ exercise prices were greater than the average market price of Quanta’s common stock. For the three months ended March 31, 2007, the effect of assuming conversion of the 4.0% convertible subordinated notes would have

been antidilutive and they were therefore excluded from the calculation of diluted earnings per share. For the three months ended March 31, 2008, the effect of assuming conversion of the 3.75% convertible subordinated notes would have been antidilutive and they were therefore excluded from the calculation of diluted earnings per share.


7.	DEBT:

Credit Facility

Quanta has a credit facility with various lenders that provides for a $475.0 million senior secured revolving credit facility maturing on September 19, 2012. Subject to the conditions specified in the credit facility, Quanta has the option to increase the revolving commitments under the credit facility by up to an additional $125.0 million from time to time upon receipt of additional commitments from new or existing lenders. Borrowings under the credit facility are to be used for working capital, capital expenditures and other general corporate purposes. The entire unused portion of the credit facility is available for the issuance of letters of credit.

As of March 31, 2008, Quanta had approximately $173.9 million of letters of credit issued under the credit facility and no outstanding revolving loans. The remaining $301.1 million was available for revolving loans or issuing new letters of credit. Amounts borrowed under the credit facility bear interest, at Quanta’s option, at a rate equal to either (a) the Eurodollar Rate (as defined in the credit facility) plus 0.875% to 1.75%, as determined by the ratio of Quanta’s total funded debt to consolidated EBITDA (as defined in the credit facility), or (b) the base rate (as described below) plus 0.00% to 0.75%, as determined by the ratio of Quanta’s total funded debt to consolidated EBITDA. Letters of credit issued under the credit facility are subject to a letter of credit fee of 0.875% to 1.75%, based on the ratio of Quanta’s total funded debt to consolidated EBITDA. Quanta is also subject to a commitment fee of 0.15% to 0.35%, based on the ratio of its total funded debt to consolidated EBITDA, on any unused availability under the credit facility. The base rate equals the higher of (i) the Federal Funds Rate (as defined in the credit facility) plus1/2 of 1% and (ii) the bank’s prime rate.

The credit facility contains certain covenants, including covenants with respect to maximum funded debt to consolidated EBITDA, maximum senior debt to consolidated EBITDA and minimum interest coverage, in each case as specified in the credit facility. For purposes of calculating the maximum funded debt to consolidated EBITDA ratio and the maximum senior debt to consolidated EBITDA ratio, Quanta’s maximum funded debt and maximum senior debt are reduced by all cash and cash equivalents (as defined in the credit facility) held by Quanta in excess of $25.0 million. As of March 31, 2008, Quanta was in compliance with all of its covenants. The credit facility limits certain acquisitions, mergers and consolidations, capital expenditures, asset sales and prepayments of indebtedness and, subject to certain exceptions, prohibits liens on material assets. The credit facility also limits the payment of dividends and stock repurchase programs in any fiscal year except those payments or other distributions payable solely in capital stock. The credit facility provides for customary events of default and carries cross-default provisions with all of Quanta’s existing subordinated notes, its continuing indemnity and security agreement with its sureties and all of its other debt instruments exceeding $15.0 million in borrowings. If an event of default (as defined in the credit facility) occurs and is continuing, on the terms and subject to the conditions set forth in the credit facility, amounts outstanding under the credit facility may be accelerated and may become or be declared immediately due and payable.

The credit facility is secured by a pledge of all of the capital stock of Quanta’s U.S. subsidiaries, 65% of the capital stock of its foreign subsidiaries and substantially all of its assets. Quanta’s U.S. subsidiaries guarantee the repayment of all amounts due under the credit facility. Quanta’s obligations under the credit facility constitute designated senior indebtedness under its 3.75% and 4.5% convertible subordinated notes. The capital stock and assets of certain of Quanta’s regulated U.S. subsidiaries acquired in the Merger will not be pledged under the credit facility, and these subsidiaries will also not be included as guarantors under the credit facility, until regulatory approval to do so is obtained.

4.0% Convertible Subordinated Notes

During the first quarter of 2007, Quanta had outstanding $33.3 million aggregate principal amount of 4.0% convertible subordinated notes (4.0% Notes), which matured on July 1, 2007. The outstanding principal balance of the 4.0% Notes plus accrued interest were repaid on July 2, 2007, the first business day after the maturity date.

4.5% Convertible Subordinated Notes

At March 31, 2008, Quanta had outstanding approximately $270.0 million aggregate principal amount of 4.5% convertible subordinated notes due 2023 (4.5% Notes). The resale of the notes and the shares issuable upon conversion thereof was registered for the benefit of the holders in a shelf registration statement filed with the SEC. The 4.5% Notes require semi-annual interest payments on April 1 and October 1, until the notes mature on October 1, 2023.

The 4.5% Notes are convertible into shares of Quanta’s common stock based on an initial conversion rate of 89.7989 shares of Quanta’s common stock per $1,000 principal amount of 4.5% Notes (which is equal to an initial conversion price of approximately $11.14 per share), subject to adjustment as a result of certain events. The 4.5% Notes are convertible by the holder (i) during any fiscal quarter if the last reported sale price of Quanta’s common stock is greater than or equal to 120% of the conversion price for at least 20 trading days in the period of 30 consecutive trading days ending on the first trading day of such fiscal quarter, (ii) during the five business day period after any five consecutive trading day period in which the trading price per note for each day of that period was less than 98% of the product of the last reported sale price of Quanta’s common stock and the conversion rate, (iii) upon Quanta calling the notes for redemption or (iv) upon the occurrence of specified corporate transactions. If the notes become convertible under any of these circumstances, Quanta has the option to deliver cash, shares of Quanta’s common stock or a combination thereof, with the amount of cash determined in accordance with the terms of the indenture under which the notes were issued. The market price condition described in clause (i) above has been satisfied for each of the quarters since the fourth quarter of 2005, and therefore the notes were convertible at the option of the holder. The outstanding notes are presently convertible at the option of each holder, and the conversion period will expire on June 30, 2008, but may continue or resume in future periods upon the satisfaction of the market price condition or other conditions.

Beginning October 8, 2008, Quanta may redeem for cash some or all of the 4.5% Notes at the principal amount thereof plus accrued and unpaid interest. The holders of the 4.5% Notes may require Quanta to repurchase all or some of their notes at the principal amount thereof plus accrued and unpaid interest on each of October 1, 2008, October 1, 2013 or October 1, 2018, or upon the occurrence of a fundamental change, as defined by the indenture under which Quanta issued the notes. Quanta must pay any required repurchases on October 1, 2008 in cash. For all other required repurchases, Quanta has the option to deliver cash, shares of its common stock or a combination thereof to satisfy its repurchase obligation. If Quanta were to satisfy any required repurchase obligation with shares of its common stock, the number of shares delivered will equal the dollar amount to be paid in common stock divided by 98.5% of the market price of Quanta’s common stock, as defined by the indenture. The right to settle for shares of common stock can be surrendered by Quanta. The 4.5% Notes carry cross-default provisions with Quanta’s other debt instruments exceeding $10.0 million in borrowings, which includes Quanta’s existing credit facility.

In October 2007, Quanta reclassified the $270.0 million aggregate principal amount outstanding of the 4.5% Notes into a current obligation as the holders may elect repayment of the 4.5% Notes in cash on October 1, 2008. Quanta has not yet determined whether it will use cash on hand, issue equity or incur debt to fund this cash obligation in the event the holders elect repayment or if Quanta elects to redeem the 4.5% Notes.

3.75% Convertible Subordinated Notes

At March 31, 2008, Quanta had outstanding $143.8 million aggregate principal amount of 3.75% convertible subordinated notes due 2026 (3.75% Notes). The resale of the notes and the shares issuable upon conversion thereof was registered for the benefit of the holders in a shelf registration statement filed with the SEC. The 3.75% Notes mature on April 30, 2026 and bear interest at the annual rate of 3.75%, payable semi-annually on April 30 and October 30, until maturity.

The 3.75% Notes are convertible into Quanta’s common stock, based on an initial conversion rate of 44.6229 shares of Quanta’s common stock per $1,000 principal amount of 3.75% Notes (which is equal to an initial conversion price of approximately $22.41 per share), subject to adjustment as a result of certain events. The 3.75% Notes are convertible by the holder (i) during any fiscal quarter if the closing price of Quanta’s common stock is greater than 130% of the conversion price for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter, (ii) upon Quanta calling the 3.75% Notes for redemption, (iii) upon the occurrence of specified distributions to holders of Quanta’s common stock or specified corporate transactions or (iv) at any time on or after March 1, 2026 until the business day immediately preceding the maturity date of the 3.75% Notes. The 3.75% Notes are not presently convertible. If the 3.75% Notes become convertible under any of these circumstances, Quanta has the option to deliver cash, shares of Quanta’s common stock or a combination thereof, with the amount of cash determined in accordance with the terms of the indenture under which the notes were issued. The holders of the 3.75% Notes who convert their notes in connection with certain change in control transactions, as defined in the indenture, may be entitled to a make whole premium in the form of an increase in the conversion rate. In the event of a change in control, in lieu of paying holders a make whole premium, if applicable, Quanta may elect, in some circumstances, to adjust the conversion rate and related conversion obligations so that the 3.75% Notes are convertible into shares of the acquiring or surviving company.

Beginning on April 30, 2010 until April 30, 2013, Quanta may redeem for cash all or part of the 3.75% Notes at a price equal to 100% of the principal amount plus accrued and unpaid interest, if the closing price of Quanta’s common stock is equal to or greater than 130% of the conversion price then in effect for the 3.75% Notes for at least 20 trading days in the 30 consecutive trading day period ending on the trading day immediately prior to the date of mailing of the notice of redemption. In addition, Quanta may redeem for cash all or part of the 3.75% Notes at any time on or after April 30, 2010 at certain redemption prices, plus accrued and unpaid interest. Beginning with the six-month interest period commencing on April 30, 2010, and for each six-month interest period thereafter, Quanta will be required to pay contingent interest on any outstanding 3.75% Notes during the applicable interest period if the average trading price of the 3.75% Notes reaches a specified threshold. The contingent interest payable within any applicable interest period will equal an annual rate of 0.25% of the average trading price of the 3.75% Notes during a five trading day reference period.

The holders of the 3.75% Notes may require Quanta to repurchase all or a part of the notes in cash on each of April 30, 2013, April 30, 2016 and April 30, 2021, and in the event of a change in control of Quanta, as defined in the indenture, at a purchase price equal to 100% of the principal amount of the 3.75% Notes plus accrued and unpaid interest. The 3.75% Notes carry cross-default provisions with Quanta’s other debt instruments exceeding $20.0 million in borrowings, which includes Quanta’s existing credit facility.


8.	STOCKHOLDERS’ EQUITY:

Treasury Stock

Pursuant to the stock incentive plans described in Note 5, employees may elect to satisfy their tax withholding obligations upon vesting of restricted stock by having Quanta make such tax payments and withhold a number of vested shares having a value on the date of vesting equal to their tax withholding obligation. As a result of such employee elections, during the first quarter of 2008, Quanta withheld 172,702 shares of Quanta common stock with

QUANTA SERVICES INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

a total market value of $4.1 million for settlement of employee tax liabilities. These shares were accounted for as treasury stock. Under Delaware corporate law, treasury stock is not entitled to vote or be counted for quorum purposes.

9. SEGMENT INFORMATION:

Prior to January 1, 2008, Quanta aggregated each of its individual operating units into one reportable segment as a specialty contractor. Beginning January 1, 2008, Quanta began reporting its results under two business segments, which are the Infrastructure Services and Dark Fiber segments described in Note 1. The Infrastructure Services segment provides comprehensive network solutions to the electric power, gas, telecommunications and cable television industries, including designing, installing, repairing and maintaining network infrastructure. In addition, the Infrastructure Services segment provides ancillary services such as inside electrical wiring, intelligent traffic networks, cable and control systems for light rail lines, airports and highways, and specialty rock trenching, directional boring and road milling for industrial and commercial customers. The Dark Fiber segment leases point-to-point fiber-optic telecommunications infrastructure in select markets and provides related design, procurement, construction and maintenance services. The Dark Fiber segment services large industrial and financial services customers, school districts and other entities with high bandwidth telecommunication needs. The telecommunication services provided through this business are subject to regulation by the Federal Communications Commission and certain state public utility commissions. The Dark Fiber segment was acquired August 30, 2007 as part of the InfraSource Merger. Accordingly, Quanta’s results of operations for the three months ended March 31, 2007 did not include any impact from the dark fiber business, and segment reporting is only provided for the three month period ended March 31, 2008.

As discussed previously, portions of the allocation of purchase price related to the Merger are preliminary, specifically, the valuation of the Dark Fiber segment and the associated customer leases, as well as the values for intangible assets. The current allocations are based on the significant use of estimates and on information that was available to management at the time these condensed consolidated financial statements were prepared. Therefore, the following results by segment are subject to change and may change materially. Corporate costs not readily identifiable to a reportable segment are allocated based upon each segment’s revenue contribution to consolidated revenues. The results of operations for the three months ended March 31, 2008 are as follows (in thousands):


	Infrastructure				Total
	Services		Dark Fiber		Reportable
	Segment		Segment		Segments

The following table presents information regarding revenues derived from the various industries served by Quanta aggregated by type of work. For the three months ended March 31, 2007, this information had previously been reported by type of customer. Accordingly, revenues related to the three months ended March 31, 2007 have

Foreign Operations

Quanta does not have significant operations or long-lived assets in countries outside of the United States. Quanta derived $15.7 million and $24.4 million of its revenues from foreign operations, the majority of which was earned in Canada, during the three months ended March 31, 2007 and 2008.


10.	COMMITMENTS AND CONTINGENCIES:

Leases

Quanta leases certain land, buildings and equipment under non-cancelable lease agreements, including related party leases. The terms of these agreements vary from lease to lease, including some with renewal options and escalation clauses. The following schedule shows the future minimum lease payments under these leases as of March 31, 2008 (in thousands):


	Operating
	Leases

Year Ending December 31 —
Remainder of 2008	$	47,907
2009		43,782
2010		32,822
2011		26,189
2012		16,297
Thereafter		22,279

Total minimum lease payments	$	189,276

Rent expense related to operating leases was approximately $16.1 million and $26.4 million for the three months ended March 31, 2007 and 2008.

Quanta has guaranteed the residual value on certain of its equipment operating leases. Quanta guarantees the difference between this residual value and the fair market value of the underlying asset at the date of termination of the leases. At March 31, 2008, the maximum guaranteed residual value was approximately $144.9 million. Quanta believes that no significant payments will be made as a result of the difference between the fair market value of the leased equipment and the guaranteed residual value. However, there can be no assurance that significant payments will not be required in the future.

QUANTA SERVICES INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Committed Capital Expenditures

Quanta has committed various amounts of capital for expansion of its dark fiber network. Quanta does not commit capital to new network expansions until it has a committed lease arrangement in place with at least one customer. The amounts of committed capital expenditures are estimates of costs required to build the networks under contract. The actual capital expenditures related to building the networks could vary materially from these estimates. As of March 31, 2008, Quanta estimates these expenditures to be approximately $64.7 million for the period April 1, 2008 through December 31, 2008 and $48.8 million and $1.0 million for the years ended December 31, 2009 and 2010.

Litigation

InfraSource, certain of its officers and directors and various other parties, including David R. Helwig, the former chief executive officer of InfraSource who became a director of Quanta after completion of the Merger, were defendants in a lawsuit seeking unspecified damages filed in the State District Court in Harris County, Texas on September 21, 2005. The plaintiffs alleged that the defendants violated their fiduciary duties and committed constructive fraud by failing to maximize shareholder value in connection with certain acquisitions by InfraSource Incorporated that closed in 1999 and 2000 and the acquisition of InfraSource Incorporated by InfraSource in 2003 and committed other acts of misconduct following the filing of the petition. The parties to this litigation settled the material claims in January 2008, and the lawsuit was dismissed by the court on March 4, 2008. The amount of the settlement was reserved in 2007, and therefore the payment of the settlement amount had no impact on Quanta’s results of operations for the first quarter of 2008.

Quanta is also from time to time party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, breach of contractand/or property damages, punitive damages, civil penalties or other losses, or injunctive or declaratory relief. With respect to all such lawsuits, claims and proceedings, Quanta records reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. Quanta does not believe that any of these proceedings, separately or in the aggregate, would be expected to have a material adverse effect on Quanta’s financial position, results of operations or cash flows.

Concentration of Credit Risk

Financial instruments that may potentially subject Quanta to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. Quanta maintains substantially all of its cash investments with what it believes to be high credit quality financial institutions. Quanta grants credit under normal payment terms, generally without collateral, to its customers, which include electric power and gas companies, telecommunications and cable television system operators, governmental entities, general contractors, and builders, owners and managers of commercial and industrial properties located primarily in the United States. Consequently, Quanta is subject to potential credit risk related to changes in business and economic factors throughout the United States. However, Quanta generally has certain statutory lien rights with respect to services provided. Under certain circumstances such as foreclosures or negotiated settlements, Quanta may take title to the underlying assets in lieu of cash in settlement of receivables. Some of Quanta’s customers have experienced significant financial difficulties. These economic conditions expose Quanta to increased risk related to collectibility of receivables for services Quanta has performed. No customer accounted for more than 10% of accounts receivable as of December 31, 2007 or March 31, 2008 or revenues for the three months ended March 31, 2007 or 2008.

Self-Insurance

Quanta is insured for employer’s liability and general liability claims, subject to a deductible of $1.0 million per occurrence, and for auto liability subject to a deductible of $3.0 million per occurrence. Quanta is also insured for workers’ compensation claims, subject to a deductible of $2.0 million per occurrence. Additionally, Quanta is

QUANTA SERVICES INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

subject to an annual cumulative aggregate liability of up to $1.0 million on workers’ compensation claims in excess of $2.0 million per occurrence. Quanta also has an employee health care benefits plan for employees not subject to collective bargaining agreements, which is subject to a deductible of $350,000 per claimant per year beginning January 1, 2008.

Effective upon the Merger, InfraSource became insured under Quanta’s property and casualty and health insurance programs. Previously, InfraSource was insured for workers’ compensation, general liability and employer’s liability, each subject to a deductible of $0.75 million per occurrence. InfraSource was also insured for auto liability, subject to a deductible of $0.5 million per occurrence. InfraSource continued to operate its own health plan for employees not subject to collective bargaining agreements through December 31, 2007, which was subject to a deductible of $150,000 per claimant per year.

Losses under all of these insurance programs are accrued based upon Quanta’s estimates of the ultimate liability for claims reported and an estimate of claims incurred but not reported, with assistance from third-party actuaries. However, insurance liabilities are difficult to assess and estimate due to unknown factors, including the severity of an injury, the determination of Quanta’s liability in proportion to other parties, the number of incidents not reported and the effectiveness of our safety program. The accruals are based upon known facts and historical trends and management believes such accruals to be adequate. As of December 31, 2007 and March 31, 2008, the gross amount accrued for self-insurance claims totaled $152.0 million and $153.7 million, with $110.1 million and $112.4 million considered to be long-term and included in other non-current liabilities. Related insurance recoveries/receivables as of December 31, 2007 and March 31, 2008 were $22.1 million and $24.2 million, of which $11.9 million and $14.2 million are included in prepaid expenses and other current assets and $10.2 million and $10.0 million are included in other assets, net.

Quanta’s casualty insurance carrier for the policy periods from August 1, 2000 to February 28, 2003 has been experiencing financial distress but is currently paying valid claims. In the event that this insurer’s financial situation further deteriorates, Quanta may be required to pay certain obligations that otherwise would have been paid by this insurer. Quanta estimates that the total future claim amount that this insurer is currently obligated to pay on its behalf for the above mentioned policy periods is approximately $4.4 million; however, the estimate of the potential range of these future claim amounts is between $2.0 million and $8.3 million. The actual amounts ultimately paid by Quanta in connection with such claims, if any, may vary materially from the above range and could be impacted by further claims development and the extent to which the insurer could not honor its obligations. Quanta continues to monitor the financial situation of this insurer and analyze any alternative actions that could be pursued. In any event, Quanta does not expect any failure by this insurer to honor its obligations to it, or any alternative actions that Quanta may pursue, to have a material adverse impact on its financial condition; however, the impact could be material to Quanta’s consolidated results of operations or cash flow in a given period.

Letters of Credit

Certain of Quanta’s vendors require letters of credit to ensure reimbursement for amounts they are disbursing on its behalf, such as to beneficiaries under its self-funded insurance programs. In addition, from time to time some customers require Quanta to post letters of credit to ensure payment to its subcontractors and vendors under those contracts and to guarantee performance under its contracts. Such letters of credit are generally issued by a bank or similar financial institution. The letter of credit commits the issuer to pay specified amounts to the holder of the letter of credit if the holder demonstrates that Quanta has failed to perform specified actions. If this were to occur, Quanta would be required to reimburse the issuer of the letter of credit. Depending on the circumstances of such a reimbursement, Quanta may also have to record a charge to earnings for the reimbursement. Quanta does not believe that it is likely that any material claims will be made under a letter of credit in the foreseeable future.

As of March 31, 2008, Quanta had $173.9 million in letters of credit outstanding under its credit facility primarily to secure obligations under its casualty insurance program. These are irrevocable stand-by letters of credit

QUANTA SERVICES INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

with maturities expiring at various times throughout 2008 and 2009. Upon maturity, it is expected that the majority of these letters of credit will be renewed for subsequent one-year periods.

Performance Bonds and Parent Guarantees

In certain circumstances, Quanta is required to provide performance bonds in connection with its contractual commitments. Quanta has indemnified its sureties for any expenses paid out under these performance bonds. As of March 31, 2008, the total amount of outstanding performance bonds was approximately $912.0 million, and the estimated cost to complete these bonded projects was approximately $272.7 million.

Quanta, from time to time, guarantees the obligations of its wholly owned subsidiaries, including obligations under certain contracts with customers, certain lease obligations and, in some states, obligations in connection with obtaining contractors licenses.

Employment Agreements

Quanta has various employment agreements with certain executives and other employees, which provide for compensation and certain other benefits and for severance payments under certain circumstances. Certain employment agreements also contain clauses that become effective upon a change of control of Quanta. In addition, employment agreements between InfraSource and certain of its executives and employees included provisions that became effective upon termination of employment within a specified time period following the change of control of InfraSource. Upon the occurrence of any of the defined events in the various employment agreements, Quanta will pay certain amounts to the employee, which vary with the level of the employee’s responsibility.

Collective Bargaining Agreements

Certain of Quanta’s subsidiaries are party to various collective bargaining agreements with certain of their employees. The agreements require such subsidiaries to pay specified wages and provide certain benefits to their union employees. These agreements expire at various times and have typically been renegotiated and renewed on terms similar to the ones contained in the expiring agreements.

Indemnities

Quanta has indemnified various parties against specified liabilities that those parties might incur in the future in connection with Quanta’s previous acquisitions of certain companies. The indemnities under acquisition agreements usually are contingent upon the other party incurring liabilities that reach specified thresholds. Quanta also generally indemnifies its customers for the services it provides under its contracts, as well as other specified liabilities, which may subject Quanta to indemnity claims and liabilities and related litigation. As of March 31, 2008, Quanta is not aware of circumstances that would lead to future indemnity claims against it for material amounts in connection with these indemnity obligations.


11.	SUBSEQUENT EVENT:

In April 2008, Quanta acquired a telecommunication and cable construction company for a purchase price, including an estimated post-closing purchase price adjustment for net working capital, of approximately $39.0 million, consisting of approximately $24.1 million in cash and 593,470 shares of Quanta common stock valued at approximately $14.9 million at the date of acquisition on a discounted basis as a result of the restricted nature of the shares. The acquisition allows Quanta to further expand its telecommunications and cable capabilities in the southwestern United States.


Item 2.	*Management’s Discussion and Analysis of Financial Condition and Results of Operations.*

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report onForm 10-Q and with our Annual Report onForm 10-K for the year ended December 31, 2007, which was filed with the SEC on February 29, 2008 and is available on the SEC’s website at www.sec.gov and on our website, which is www.quantaservices.com. The discussion below contains forward-looking statements that are based upon our current expectations and are subject to uncertainty and changes in circumstances. Actual results may differ materially from these expectations due to inaccurate assumptions and known or unknown risks and uncertainties, including those identified under the headings “Uncertainty of Forward-Looking Statements and Information” below in this Item 2 and “Risk Factors” in Item 1A of Part II of this Quarterly Report.

Introduction

We are a leading national provider of specialty contracting services. Beginning January 1, 2008, we began reporting our results under two business segments. The infrastructure services (Infrastructure Services) segment provides specialized contracting services, offeringend-to-end network solutions to the electric power, gas, telecommunications and cable television industries. Specifically, the comprehensive services provided by the Infrastructure Services segment include designing, installing, repairing and maintaining network infrastructure, as well as certain ancillary services. Additionally, the dark fiber construction and leasing (Dark Fiber) segment, which was acquired on August 30, 2007 in the Merger as described below, leasespoint-to-point fiber-optic telecommunications infrastructure in select markets and provides related design, procurement, construction and maintenance services. The Dark Fiber segment services large industrial and financial services customers, school districts and other entities with high bandwidth telecommunication needs. The telecommunication services provided through this business are subject to regulation by the Federal Communications Commission and certain state public utility commissions. Prior to January 1, 2008, we reported results under one business segment, which consisted primarily of the services now under the Infrastructure Services segment.

On August 30, 2007, we acquired, through a merger transaction (the Merger), all of the outstanding common stock of InfraSource Services, Inc. (InfraSource). Similar to us, InfraSource provided design, procurement, construction, testing and maintenance services to electric power utilities, natural gas utilities, telecommunication customers, government entities and heavy industrial companies, such as petrochemical, processing and refining businesses, primarily in the United States. As a result of the Merger, we enhanced and expanded our position as a leading specialized contracting services company serving the electric power, gas, telecommunications and cable television industries and added a dark fiber construction and leasing business. The dark fiber construction and leasing business is now reported as a separate business segment.

We had consolidated revenues for the three months ended March 31, 2008 of approximately $844.4 million, of which 58% was attributable to electric power work, 16% to gas work, 17% to telecommunications and cable television work and 7.4% to ancillary services, such as inside electrical wiring, intelligent traffic networks, fueling systems, cable and control systems for light rail lines, airports and highways and specialty rock trenching, directional boring and road milling for industrial and commercial customers. In addition, 1.6% of our consolidated revenues for the three months ended March 31, 2008 relates to our Dark Fiber segment.

Our customers include many of the leading companies in the industries we serve. We have developed strong strategic alliances with numerous customers and strive to develop and maintain our status as a preferred vendor to our customers. In our Infrastructure Services segment, we enter into various types of contracts, including competitive unit price, hourly rate, cost-plus (or time and materials basis), and fixed price (or lump sum basis), the final terms and prices of which we frequently negotiate with the customer. Although the terms of our contracts vary considerably, most are made on either a unit price or fixed price basis in which we agree to do the work for a price per unit of work performed (unit price) or for a fixed amount for the entire project (fixed price). We complete a substantial majority of our fixed price projects within one year, while we frequently provide maintenance and repair work under open-ended unit price or cost-plus master service agreements that are renewable annually.

For our Infrastructure Services segment, we recognize revenue on our unit price and cost-plus contracts when units are completed or services are performed. For our fixed price contracts, we record revenues as work on the

contract progresses on apercentage-of-completion basis. Under this valuation method, revenue is recognized based on the percentage of total costs incurred to date in proportion to total estimated costs to complete the contract. Fixed price contracts generally include retainage provisions under which a percentage of the contract price is withheld until the project is complete and has been accepted by our customer.

The Dark Fiber segment constructs and leases fiber-optic telecommunications facilities to customers pursuant to licensing agreements, typically with lease terms from five to twenty-five years, including certain renewal options. Under those agreements, customers lease a portion of the capacity of a fiber-optic facility, with the facility owned and maintained by us. Revenues earned pursuant to these fiber-optic facility licensing agreements, including any initial fees or advanced billings, are recognized ratably over the expected length of the agreements, including probable renewal periods.

Seasonality; Fluctuations of Results

Our revenues and results of operations can be subject to seasonal and other variations. These variations are influenced by weather, customer spending patterns, bidding seasons, project schedules and timing and holidays. Typically, our revenues are lowest in the first quarter of the year because cold, snowy or wet conditions cause delays. The second quarter is typically better than the first, as some projects begin, but continued cold and wet weather can often impact second quarter productivity. The third quarter is typically the best of the year, as a greater number of projects are underway and weather is more accommodating to work on projects. Revenues during the fourth quarter of the year are typically lower than the third quarter but higher than the second quarter. Many projects are completed in the fourth quarter and revenues often are impacted positively by customers seeking to spend their capital budget before the end of the year; however, the holiday season and inclement weather sometimes can cause delays and thereby reduce revenues and increase costs.

Additionally, our industry can be highly cyclical. As a result, our volume of business may be adversely affected by declines or delays in new projects in various geographic regions in the United States. Project schedules, in particular in connection with larger, longer-term projects, can also create fluctuations in the services provided under projects, which may adversely affect us in a given quarter. The financial condition of our customers and their access to capital, variations in the margins of projects performed during any particular quarter, regional and national economic conditions, timing of acquisitions, the timing and magnitude of acquisition assimilation costs and interest rate fluctuations may also materially affect quarterly results. Accordingly, our operating results in any particular quarter or year may not be indicative of the results that can be expected for any other quarter or for any other year. You should read“Outlook”and“Understanding Gross Margins”for additional discussion of trends and challenges that may affect our financial condition and results of operations.

Understanding Gross Margins

Our gross margin is gross profit expressed as a percentage of revenues. Cost of services, which is subtracted from revenues to obtain gross profit, consists primarily of salaries, wages and benefits to employees, depreciation, fuel and other equipment expenses, equipment rentals, subcontracted services, insurance, facilities expenses, materials and parts and supplies. Various factors — some controllable, some not — impact our gross margins on a quarterly or annual basis.

Seasonal and Geographical. As discussed above, seasonal patterns can have a significant impact on gross margins. Generally, business is slower in the winter months versus the warmer months of the year. This can be offset somewhat by increased demand for electrical service and repair work resulting from severe weather. In addition, the mix of business conducted in different parts of the country will affect margins, as some parts of the country offer the opportunity for higher gross margins than others.

Weather. Adverse or favorable weather conditions can impact gross margins in a given period. For example, it is typical in the first quarter of any fiscal year that parts of the country may experience snow or rainfall that may negatively impact our revenues and gross margin due to reduced productivity. In many cases, projects may be delayed or temporarily placed on hold. Conversely, in periods when weather remains dry and temperatures are accommodating, more work can be done, sometimes with less cost, which would have a favorable impact on gross

margins. In some cases, severe weather, such as hurricanes and ice storms, can provide us with high margin emergency service restoration work, which generally has a positive impact on margins.

Revenue Mix. The mix of revenues derived from the industries we serve will impact gross margins. Changes in our customers’ spending patterns in each of the industries we serve can cause an imbalance in supply and demand and, therefore, affect margins and mix of revenues by the industry we served.

Service and Maintenance versus Installation. Installation work is often obtained on a fixed price basis, while maintenance work is often performed under pre-established or negotiated prices or cost-plus pricing arrangements. Gross margins for installation work may vary from project to project, and can be higher than maintenance work, because work obtained on a fixed price basis has higher risk than other types of pricing arrangements. We typically derive approximately 50% of our annual revenues from maintenance work, but a higher portion of installation work in any given quarter may affect our gross margins for that quarter.

Subcontract Work. Work that is subcontracted to other service providers generally yields lower gross margins. An increase in subcontract work in a given period may contribute to a decrease in gross margin. We typically subcontract approximately 10% to 15% of our work to other service providers.

Materials versus Labor. Margins may be lower on projects on which we furnish materials as ourmark-up on materials is generally lower than on labor costs. In a given period, a higher percentage of work that has a higher materials component may decrease overall gross margin.

Depreciation. We include depreciation in cost of services. This is common practice in our industry, but it can make comparability to other companies difficult. This must be taken into consideration when comparing us to other companies.

Insurance. Gross margins could be impacted by fluctuations in insurance accruals as additional claims arise and as circumstances and conditions of existing claims change. We are insured for employer’s liability and general liability claims, subject to a deductible of $1.0 million per occurrence, and for auto liability subject to a deductible of $3.0 million per occurrence. We are also insured for workers’ compensation claims, subject to a deductible of $2.0 million per occurrence. Additionally, we are subject to an annual cumulative aggregate liability of up to $1.0 million on workers’ compensation claims in excess of $2.0 million per occurrence. We also have an employee health care benefits plan for employees not subject to collective bargaining agreements, which is subject to a deductible of $350,000 per claimant per year beginning January 1, 2008.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of compensation and related benefits to management, administrative salaries and benefits, marketing, office rent and utilities, communications, professional fees, bad debt expense, letter of credit fees and gains and losses on the sale of property and equipment.

Results of Operations

In accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” the results of operations data below does not reflect the operations of Environmental Professional Associates, Limited (EPA) in any periods since EPA’s results of operations are reported as discontinued operations in our accompanying condensed consolidated statements of operations. Accordingly, the 2007 amounts below do not agree to the amounts previously reported. Additionally, the results of operations for the first quarter of 2007 do not include any results of operations from InfraSource as the Merger did not occur until August 30, 2007.

The following table sets forth selected statements of operations data and such data as a percentage of revenues for the three months indicated (dollars in thousands):

Three months ended March 31, 2008 compared to the three months ended March 31, 2007

Revenues. Revenues increased $275.5 million, or 48.4%, to $844.4 million for the three months ended March 31, 2008. Electric power services increased by approximately $150.5 million, or 44.6%, gas services increased by $58.3 million, or 74.6%, and telecommunications and cable television network services increased by approximately $74.3 million, or 106.6%. In addition to the contribution of revenues from the InfraSource operating units acquired through the Merger, revenues were favorably impacted by an increased number and size of projects as a result of larger capital budgets for our customers, specifically in connection with electric transmission projects and fiber build-out initiatives, as well as improved pricing. Additionally, revenues increased due to the impact of $13.2 million in revenues in the first quarter of 2008 from the Dark Fiber segment acquired as part of the Merger. Partially offsetting these increases was a decrease of approximately $33 million in emergency restoration services, from $53 million in the first quarter of 2007 to $22 million in the first quarter of 2008. Also, ancillary services revenues decreased approximately $20.8 million, or 25.0%, primarily due to the timing of projects.

Gross profit. Gross profit increased $46.3 million, or 59.7%, to $123.9 million for the three months ended March 31, 2008. The increase in gross profit results primarily from the contribution of the InfraSource operating units acquired through the Merger coupled with the effect of the increased revenues discussed above. As a percentage of revenues, gross margin increased from 13.6% for the three months ended March 31, 2007 to 14.7% for the three months ended March 31, 2008. The increase in gross margin is primarily due to improved pricing, the contribution of the higher margin Dark Fiber segment acquired as part of the Merger and better fixed costs absorption as a result of higher revenues. Partially offsetting these increases was a lower amount of emergency restoration services, which typically generate higher margins, performed in the first quarter of 2008 as compared to the first quarter of 2007.

Selling, general and administrative expenses. Selling, general and administrative expenses increased $21.8 million, or 44.5%, to $70.7 million for the three months ended March 31, 2008. The increase in selling, general and administrative expenses was primarily a result of the addition of administrative expenses associated with the InfraSource operating units acquired through the Merger, and higher salaries and benefits associated with increased personnel, salary increases and increased performance bonuses. As a percentage of revenues, selling, general and administrative expenses decreased from 8.6% to 8.4%.

Amortization of intangible assets. Amortization of intangible assets increased $9.8 million to $10.6 million for the three months ended March 31, 2008. This increase is attributable to the amortization of intangible assets associated with acquisitions completed since the first quarter of 2007, primarily the acquisition of InfraSource.

Interest expense. Interest expense for the three months ended March 31, 2008 decreased $0.4 million as compared to the three months ended March 31, 2007, primarily due to the repayment of our 4.0% convertible subordinated notes on July 2, 2007.

Interest income. Interest income was $4.0 million for the quarter ended March 31, 2008, compared to $4.3 million for the quarter ended March 31, 2007. The decrease results primarily from lower interest rates partially offset by a higher average cash balance for the quarter ended March 31, 2008 as compared to the quarter ended March 31, 2007.

Provision (benefit) for income taxes. The provision for income taxes was $17.3 million for the three months ended March 31, 2008, with an effective tax rate of 41.7%. During the three months ended March 31, 2007, Quanta recorded $15.3 million in tax benefits primarily due to a decrease in reserves for uncertain tax positions resulting from the settlement of a multi-year Internal Revenue Service audit. Excluding this discrete period benefit, the provision for income taxes was $11.1 million for the three months ended March 31, 2007, with an effective tax rate of 41.7%.

Liquidity and Capital Resources

Cash Requirements

We anticipate that our cash and cash equivalents on hand, which totaled $372.2 million as of March 31, 2008, borrowing capacity under our credit facility, and our future cash flows from operations will provide sufficient funds to enable us to meet our future operating needs, debt service requirements and planned capital expenditures and to facilitate our future ability to grow. Initiatives to rebuild the United States electric power grid or momentum in deployment of fiber to the premises may require a significant amount of additional working capital. We also evaluate opportunities for strategic acquisitions from time to time that may require cash. We believe that we have adequate cash and availability under our credit facility to meet all such needs.

Capital expenditures are expected to be approximately $195 million for 2008. Approximately $85 million of expected 2008 capital expenditures are targeted for the expansion of our dark fiber leasing network in connection with committed leasing arrangements with customers, and the majority of the remaining expenditures will be for operating equipment in the Infrastructure Services segment.

Our 4.5% convertible subordinated notes due 2023 (4.5% Notes) are presently convertible at the option of each holder, and the conversion period will expire on June 30, 2008, but may continue or resume in future periods upon the satisfaction of the market price condition or other conditions. Our 3.75% convertible subordinated notes due 2026 (3.75% Notes) are not presently convertible. The 3.75% Notes could become convertible in future periods upon the satisfaction of the market price condition or other conditions. If any holder of the convertible notes requests to convert their notes, we have the option to deliver cash, shares of our common stock or a combination thereof, with the amount of cash determined in accordance with the terms of the indenture under which the notes were issued. Future conversions could result in the recording of losses on extinguishment of debt if the conversions are settled in cash for an amount in excess of the principal amount.

On October 1, 2008, the holders of the 4.5% Notes may elect repayment, which would require us to pay, in cash, the aggregate principal amount, plus accrued and unpaid interest, of the notes held by the holders who elect repayment. As a result of the holders’ repayment right, we reclassified the $270 million aggregate principal amount outstanding of the 4.5% Notes into a current obligation in October 2007. Additionally, at any time on or after October 8, 2008, we may redeem for cash some or all of the 4.5% Notes at the principal amount thereof, plus accrued and unpaid interest. The holders of the 4.5% Notes that are called for redemption will have the right to convert all or some of their notes, which we may satisfy by delivery of shares of our common stock, cash or a combination thereof, as described in further detail under“Debt Instruments — 4.5% Convertible Subordinated Notes.”Currently, our common stock is trading at prices in excess of the conversion price. If our common stock price exceeds the conversion price, it is not likely that any holder of the 4.5% Notes will elect repayment on October 1, 2008, but it is likely that if we were to redeem the 4.5% Notes on or after October 8, 2008, the holders of the notes subject to redemption would convert their notes. On the other hand, if our common stock price is below the conversion price, it is more likely that the holders of the 4.5% Notes would elect repayment or would not convert

upon a redemption. We have not yet determined whether we will use cash on hand, issue equity or incur debt to fund our cash obligation if we are required to repay or determine to redeem the 4.5% Notes. If a conversion obligation arises, we have also not yet determined whether we will settle it in our common stock, cash or a combination thereof.

Sources and Uses of Cash

As of March 31, 2008, we had cash and cash equivalents of $372.2 million, working capital of $566.9 million and long-term debt of $143.8 million, net of current maturities. We also had $173.9 million of letters of credit outstanding under our credit facility, leaving $301.1 million available for revolving loans or issuing new letters of credit.

Operating Activities

Operating activities provided net cash of $15.2 million during the three months ended March 31, 2008 as compared to $64.0 million in the three months ended March 31, 2007. Cash flow from operations is primarily influenced by demand for our services, operating margins and the type of services we provide, but can also be impacted by working capital needs. Cash flow for the first quarter of 2008 was negatively impacted by higher working capital requirements associated with invoice processing issues by certain customers as a result of the rapidramp-up of FTTx and wireless installations over the past six months. The specific telecommunications work being performed has voluminous billing requirements and has been subject to lengthy delays as our invoices work their way through the customer’s payment system. Additionally, revenues in March 2008 were higher than in March 2007, resulting in higher balances of accounts receivable, which increases the need for cash to fund working capital requirements.

Investing Activities

In the three months ended March 31, 2008, we used net cash in investing activities of $51.2 million as compared to $42.3 million used in investing activities in the three months ended March 31, 2007. Investing activities in the three months ended March 31, 2007 included purchases and sales of variable rate demand notes (VRDNs), which are classified as short-term investments, available for sale when held. We did not invest in VRDNs subsequent to the three months ended March 31, 2007. Other investing activities in 2008 include $53.2 million used for capital expenditures, partially offset by $2.1 million of proceeds from the sale of equipment. During the three months ended March 31, 2007, we used $25.4 million for capital expenditures, coupled with $17.7 million in net cash outlays for an acquisition closed during the first quarter of 2007, offset slightly by $0.8 million of proceeds from the sale of equipment. The $27.8 million increase in capital expenditures in the three months ended March 31, 2008 compared to the three months ended March 31, 2007 is related primarily to the growth in our business and capital expenditure requirements of our dark fiber business acquired through the Merger.

Financing Activities

In the three months ended March 31, 2008, financing activities provided net cash flow of $2.3 million as compared to $1.0 million provided by financing activities in the three months ended March 31, 2007. The $2.3 million provided by financing activities resulted primarily from $1.4 million received from the exercise of stock options. Also contributing to the inflow was $1.2 million of tax benefit from stock-based equity awards. The $1.0 million provided by financing activities in the three months ended March 31, 2007 resulted primarily from a $2.1 million tax benefit from stock-based equity awards and $0.5 million received from the exercise of stock options, partially offset by $1.6 million in net repayments of other debt.

Debt Instruments

Credit Facility

We have a credit facility with various lenders that provides for a $475.0 million senior secured revolving credit facility maturing on September 19, 2012. Subject to the conditions specified in the credit facility, we have the option to increase the revolving commitments under the credit facility by up to an additional $125.0 million from time to

time upon receipt of additional commitments from new or existing lenders. Borrowings under the credit facility are to be used for working capital, capital expenditures and other general corporate purposes. The entire unused portion of the credit facility is available for the issuance of letters of credit.

As of March 31, 2008, we had approximately $173.9 million of letters of credit issued under the credit facility and no outstanding revolving loans. The remaining $301.1 million was available for revolving loans or issuing new letters of credit. Amounts borrowed under the credit facility bear interest, at our option, at a rate equal to either (a) the Eurodollar Rate (as defined in the credit facility) plus 0.875% to 1.75%, as determined by the ratio of our total funded debt to consolidated EBITDA (as defined in the credit facility), or (b) the base rate (as described below) plus 0.00% to 0.75%, as determined by the ratio of our total funded debt to consolidated EBITDA. Letters of credit issued under the credit facility are subject to a letter of credit fee of 0.875% to 1.75%, based on the ratio of our total funded debt to consolidated EBITDA. We are also subject to a commitment fee of 0.15% to 0.35%, based on the ratio of its total funded debt to consolidated EBITDA, on any unused availability under the credit facility. The base rate equals the higher of (i) the Federal Funds Rate (as defined in the credit facility) plus1/2 of 1% and (ii) the bank’s prime rate.

The credit facility contains certain covenants, including covenants with respect to maximum funded debt to consolidated EBITDA, maximum senior debt to consolidated EBITDA and minimum interest coverage, in each case as specified in the credit facility. For purposes of calculating the maximum funded debt to consolidated EBITDA ratio and the maximum senior debt to consolidated EBITDA ratio, our maximum funded debt and maximum senior debt are reduced by all cash and cash equivalents (as defined in the credit facility) held by us in excess of $25.0 million. As of March 31, 2008, we were in compliance with all of its covenants. The credit facility limits certain acquisitions, mergers and consolidations, capital expenditures, asset sales and prepayments of indebtedness and, subject to certain exceptions, prohibits liens on material assets. The credit facility also limits the payment of dividends and stock repurchase programs in any fiscal year except those payments or other distributions payable solely in capital stock. The credit facility provides for customary events of default and carries cross-default provisions with all of our existing subordinated notes, our continuing indemnity and security agreement with our sureties and all of our other debt instruments exceeding $15.0 million in borrowings. If an event of default (as defined in the credit facility) occurs and is continuing, on the terms and subject to the conditions set forth in the credit facility, amounts outstanding under the credit facility may be accelerated and may become or be declared immediately due and payable.

The credit facility is secured by a pledge of all of the capital stock of our U.S. subsidiaries, 65% of the capital stock of our foreign subsidiaries and substantially all of our assets. Our U.S. subsidiaries guarantee the repayment of all amounts due under the credit facility. Our obligations under the credit facility constitute designated senior indebtedness under our 3.75% and 4.5% convertible subordinated notes. The capital stock and assets of certain of our regulated U.S. subsidiaries acquired in the Merger will not be pledged under the credit facility, and these subsidiaries will also not be included as guarantors under the credit facility, until regulatory approval to do so is obtained.

4.0% Convertible Subordinated Notes

During the first quarter of 2007, we had outstanding $33.3 million aggregate principal amount of 4.0% convertible subordinated notes (4.0% Notes), which matured on July 1, 2007. The outstanding principal balance of the 4.0% Notes plus accrued interest were repaid on July 2, 2007, the first business day after the maturity date.

4.5% Convertible Subordinated Notes

At March 31, 2008, we had outstanding approximately $270.0 million aggregate principal amount of the 4.5% Notes. The resale of the notes and the shares issuable upon conversion thereof was registered for the benefit of the holders in a shelf registration statement filed with the SEC. The 4.5% Notes require semi-annual interest payments on April 1 and October 1, until the notes mature on October 1, 2023.

The 4.5% Notes are convertible into shares of our common stock based on an initial conversion rate of 89.7989 shares of our common stock per $1,000 principal amount of 4.5% Notes (which is equal to an initial conversion price of approximately $11.14 per share), subject to adjustment as a result of certain events. The

4.5% Notes are convertible by the holder (i) during any fiscal quarter if the last reported sale price of our common stock is greater than or equal to 120% of the conversion price for at least 20 trading days in the period of 30 consecutive trading days ending on the first trading day of such fiscal quarter, (ii) during the five business day period after any five consecutive trading day period in which the trading price per note for each day of that period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate, (iii) upon our calling the notes for redemption or (iv) upon the occurrence of specified corporate transactions. If the notes become convertible under any of these circumstances, we have the option to deliver cash, shares of our common stock or a combination thereof, with the amount of cash determined in accordance with the terms of the indenture under which the notes were issued. The market price condition described in clause (i) above has been satisfied for each of the quarters since the fourth quarter of 2005, and therefore the notes were convertible at the option of the holder. The outstanding notes are presently convertible at the option of each holder, and the conversion period will expire on June 30, 2008, but may continue or resume in future periods upon the satisfaction of the market price condition or other conditions.

Beginning October 8, 2008, we may redeem for cash some or all of the 4.5% Notes at the principal amount thereof plus accrued and unpaid interest. The holders of the 4.5% Notes may require us to repurchase all or some of their notes at the principal amount thereof plus accrued and unpaid interest on each of October 1, 2008, October 1, 2013 or October 1, 2018, or upon the occurrence of a fundamental change, as defined by the indenture under which we issued the notes. We must pay any required repurchases on October 1, 2008 in cash. For all other required repurchases, we have the option to deliver cash, shares of our common stock or a combination thereof to satisfy our repurchase obligation. If we were to satisfy any required repurchase obligation with shares of our common stock, the number of shares delivered will equal the dollar amount to be paid in common stock divided by 98.5% of the market price of our common stock, as defined by the indenture. The right to settle for shares of common stock can be surrendered by us. The 4.5% Notes carry cross-default provisions with our other debt instruments exceeding $10.0 million in borrowings, which includes our existing credit facility.

In October 2007, we reclassified the $270.0 million aggregate principal amount outstanding of the 4.5% Notes into a current obligation as the holders may elect repayment of the 4.5% Notes in cash on October 1, 2008. We have not yet determined whether we will use cash on hand, issue equity or incur debt to fund this cash obligation in the event the holders elect repayment or if we elect to redeem the 4.5% Notes.

3.75% Convertible Subordinated Notes

At March 31, 2008, we had outstanding $143.8 million aggregate principal amount of the 3.75% Notes. The resale of the notes and the shares issuable upon conversion thereof was registered for the benefit of the holders in a shelf registration statement filed with the SEC. The 3.75% Notes mature on April 30, 2026 and bear interest at the annual rate of 3.75%, payable semi-annually on April 30 and October 30, until maturity.

The 3.75% Notes are convertible into our common stock, based on an initial conversion rate of 44.6229 shares of our common stock per $1,000 principal amount of 3.75% Notes (which is equal to an initial conversion price of approximately $22.41 per share), subject to adjustment as a result of certain events. The 3.75% Notes are convertible by the holder (i) during any fiscal quarter if the closing price of our common stock is greater than 130% of the conversion price for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter, (ii) upon us calling the 3.75% Notes for redemption, (iii) upon the occurrence of specified distributions to holders of our common stock or specified corporate transactions or (iv) at any time on or after March 1, 2026 until the business day immediately preceding the maturity date of the 3.75% Notes. The 3.75% Notes are not presently convertible. If the 3.75% Notes become convertible under any of these circumstances, we have the option to deliver cash, shares of our common stock or a combination thereof, with the amount of cash determined in accordance with the terms of the indenture under which the notes were issued. The holders of the 3.75% Notes who convert their notes in connection with certain change in control transactions, as defined in the indenture, may be entitled to a make whole premium in the form of an increase in the conversion rate. In the event of a change in control, in lieu of paying holders a make whole premium, if applicable, we may elect, in some circumstances, to adjust the conversion rate and related conversion obligations so that the 3.75% Notes are convertible into shares of the acquiring or surviving company.

Beginning on April 30, 2010 until April 30, 2013, we may redeem for cash all or part of the 3.75% Notes at a price equal to 100% of the principal amount plus accrued and unpaid interest, if the closing price of our common stock is equal to or greater than 130% of the conversion price then in effect for the 3.75% Notes for at least 20 trading days in the 30 consecutive trading day period ending on the trading day immediately prior to the date of mailing of the notice of redemption. In addition, we may redeem for cash all or part of the 3.75% Notes at any time on or after April 30, 2010 at certain redemption prices, plus accrued and unpaid interest. Beginning with the six-month interest period commencing on April 30, 2010, and for each six-month interest period thereafter, we will be required to pay contingent interest on any outstanding 3.75% Notes during the applicable interest period if the average trading price of the 3.75% Notes reaches a specified threshold. The contingent interest payable within any applicable interest period will equal an annual rate of 0.25% of the average trading price of the 3.75% Notes during a five trading day reference period.

The holders of the 3.75% Notes may require us to repurchase all or a part of the notes in cash on each of April 30, 2013, April 30, 2016 and April 30, 2021, and in the event of a change in control of the company, as defined in the indenture, at a purchase price equal to 100% of the principal amount of the 3.75% Notes plus accrued and unpaid interest. The 3.75% Notes carry cross-default provisions with our other debt instruments exceeding $20.0 million in borrowings, which includes our existing credit facility.

Off-Balance Sheet Transactions

As is common in our industry, we have entered into certain off-balance sheet arrangements in the ordinary course of business that result in risks not directly reflected in our balance sheets. Our significant off-balance sheet transactions include liabilities associated with non-cancelable operating leases, letter of credit obligations, commitments to expand our dark fiber network and surety guarantees. We have not engaged in any off-balance sheet financing arrangements through special purpose entities, and we do not guarantee the work or obligations of third parties.

Leases

We enter into non-cancelable operating leases for many of our facility, vehicle and equipment needs. These leases allow us to conserve cash by paying a monthly lease rental fee for use of facilities, vehicles and equipment rather than purchasing them. We may decide to cancel or terminate a lease before the end of its term, in which case we are typically liable to the lessor for the remaining lease payments under the term of the lease.

We have guaranteed the residual value of the underlying assets under certain of our equipment operating leases at the date of termination of such leases. We have agreed to pay any difference between this residual value and the fair market value of each underlying asset as of the lease termination date. As of March 31, 2008, the maximum guaranteed residual value was approximately $144.9 million. We believe that no significant payments will be made as a result of the difference between the fair market value of the leased equipment and the guaranteed residual value. However, there can be no assurance that future significant payments will not be required.

Letters of Credit

Certain of our vendors require letters of credit to ensure reimbursement for amounts they are disbursing on our behalf, such as to beneficiaries under our self-funded insurance programs. In addition, from time to time some customers require us to post letters of credit to ensure payment to our subcontractors and vendors under those contracts and to guarantee performance under our contracts. Such letters of credit are generally issued by a bank or similar financial institution. The letter of credit commits the issuer to pay specified amounts to the holder of the letter of credit if the holder demonstrates that we have failed to perform specified actions. If this were to occur, we would be required to reimburse the issuer of the letter of credit. Depending on the circumstances of such a reimbursement, we may also have to record a charge to earnings for the reimbursement. We do not believe that it is likely that any material claims will be made under a letter of credit in the foreseeable future.

As of March 31, 2008, we had $173.9 million in letters of credit outstanding under our credit facility primarily to secure obligations under our casualty insurance program. These are irrevocable stand-by letters of credit with

maturities expiring at various times throughout 2008 and 2009. Upon maturity, it is expected that the majority of these letters of credit will be renewed for subsequent one-year periods.

Performance Bonds and Parent Guarantees

Many customers, particularly in connection with new construction, require us to post performance and payment bonds issued by a financial institution known as a surety. These bonds provide a guarantee to the customer that we will perform under the terms of a contract and that we will pay subcontractors and vendors. If we fail to perform under a contract or to pay subcontractors and vendors, the customer may demand that the surety make payments or provide services under the bond. We must reimburse the surety for any expenses or outlays it incurs. Under our continuing indemnity and security agreement with our sureties and with the consent of our lenders under our credit facility, we have granted security interests in certain of our assets to collateralize our obligations to the sureties. In addition, under our agreement with InfraSource’s surety, which remains in place for bonds outstanding under it at the closing of the Merger, we will be required to transfer to the surety certain of our assets as collateral in the event of a default under the agreement. We may be required to post letters of credit or other collateral in favor of the sureties or our customers in the future. Posting letters of credit in favor of the sureties or our customers would reduce the borrowing availability under our credit facility. To date, we have not been required to make any reimbursements to our sureties for bond-related costs. We believe that it is unlikely that we will have to fund significant claims under our surety arrangements in the foreseeable future. As of March 31, 2008, an aggregate of approximately $912.0 million in original face amount of bonds issued by our sureties were outstanding. Our estimated cost to complete these bonded projects was approximately $272.7 million as of March 31, 2008.

From time to time, we guarantee the obligations of our wholly owned subsidiaries, including obligations under certain contracts with customers, certain lease obligations and, in some states, obligations in connection with obtaining contractors licenses.

Contractual Obligations

As of March 31, 2008, our future contractual obligations are as follows (in thousands):


			Remainder
	Total		of 2008		2009		2010		2011		2012		Thereafter

The committed capital expenditures for dark fiber networks represent commitments related to signed contracts with customers. The amounts are estimates of costs required to build the networks under contract. The actual capital expenditures related to building the networks could vary materially from these estimates.

Actual maturities may differ from contractual maturities because convertible note holders may convert their notes prior to the maturity dates or subsequent to optional maturity dates.

As of March 31, 2008, we had no borrowings under our credit facility. In addition, our multi-employer pension plan contributions are determined annually based on our union employee payrolls, which cannot be determined in advance for future periods. As of March 31, 2008, the total unrecognized tax benefit related to uncertain tax positions was $51.8 million, of which no significant amounts are anticipated to be paid within the next twelve months.

Concentration of Credit Risk

Quanta grants credit under normal payment terms, generally without collateral, to its customers, which include electric power and gas companies, telecommunications and cable television system operators, governmental entities, general contractors, and builders, owners and managers of commercial and industrial properties located primarily in the United States. Consequently, we are subject to potential credit risk related to changes in business and economic factors throughout the United States. However, we generally have certain statutory lien rights with respect to services provided. Under certain circumstances such as foreclosures or negotiated settlements, we may take title to the underlying assets in lieu of cash in settlement of receivables. Some of our customers have experienced significant financial difficulties. These economic conditions expose us to increased risk related to collectability of receivables for services we have performed. No customer accounted for more than 10% of accounts receivable as of December 31, 2007 or March 31, 2008 or revenues for the three months ended March 31, 2007 or March 31, 2008.

Litigation

InfraSource, certain of its officers and directors and various other parties, including David R. Helwig, the former chief executive officer of InfraSource who became a director of Quanta after completion of the Merger, were defendants in a lawsuit seeking unspecified damages filed in the State District Court in Harris County, Texas on September 21, 2005. The plaintiffs alleged that the defendants violated their fiduciary duties and committed constructive fraud by failing to maximize shareholder value in connection with certain acquisitions by InfraSource Incorporated that closed in 1999 and 2000 and the acquisition of InfraSource Incorporated by InfraSource in 2003 and committed other acts of misconduct following the filing of the petition. The parties to this litigation settled the material claims in January 2008 and the lawsuit was dismissed by the court on March 4, 2008. The amount of the settlement was reserved in 2007, and therefore the payment of the settlement amount had no impact on our results of operations for the first quarter of 2008.

We are from time to time party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, breach of contractand/or property damages, punitive damages, civil penalties or other losses, or injunctive or declaratory relief. With respect to all such lawsuits, claims and proceedings, we record reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. We do not believe that any of these proceedings, separately or in the aggregate, would be expected to have a material adverse effect on our financial position, results of operations or cash flows.

Related Party Transactions

In the normal course of business, we enter into transactions from time to time with related parties. These transactions typically take the form of facility leases with prior owners of certain acquired companies and payables to prior owners who are now employees.

New Accounting Pronouncements

material financial assets and liabilities recognized on our balance sheet that are impacted by the partial adoption of SFAS No. 157. Additionally, we do not currently have any material non-financial assets or liabilities that are carried at fair value on a recurring basis. However, we do have non-financial assets that are evaluated against measures of fair value on a recurring or as needed basis, including goodwill, other intangibles and long-term assets held and used. Based on the financial and non-financial assets and liabilities on our balance sheet as of March 31, 2008, we do not expect the adoption of SFAS No. 157 to have a material impact on our consolidated financial position, results of operations or cash flows.

On January 1, 2008, we adopted SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities, including an amendment of FASB No. 115.” SFAS No. 159 permits entities to choose to measure at fair value many financial instruments and certain other items at fair value that were not previously required to be measured at fair value. Unrealized gains and losses on items for which the fair value option has been elected are reported in earnings. SFAS No. 159 does not affect any existing accounting literature that requires certain assets and liabilities to be carried at fair value. The adoption of SFAS No. 159 did not have any material impact on our consolidated financial position, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 160, “Non-controlling Interests in Consolidated Financial Statements — an amendment of ARB No. 51.” SFAS No. 160 addresses the accounting and reporting framework for minority interests by a parent company. SFAS No. 160 is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. Accordingly, we will adopt SFAS No. 160, in the first quarter of fiscal 2009. Because we do not currently have any subsidiaries with noncontrolling interests, the adoption of SFAS No. 160 is not anticipated to have a material impact on our consolidated financial position, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 141(R), “Business Combinations.” SFAS No. 141(R) is effective for fiscal years beginning after December 15, 2008. Earlier application is prohibited. Assets and liabilities that arose from business combinations which occurred prior to the adoption of SFAS No. 141(R) should not be adjusted upon the adoption of SFAS No. 141(R). SFAS No. 141(R) requires the acquiring entity in a business combination to recognize all (and only) the assets acquired and liabilities assumed in the business combination; establishes the acquisition date as the measurement date to determine the fair value for all assets acquired and liabilities assumed; and requires the acquirer to disclose to investors and other users all of the information needed to evaluate and understand the nature and financial effect of the business combination. As it relates to recognizing all (and only) the assets acquired and liabilities assumed in a business combination, costs an acquirer expects but is not obligated to incur in the future to exit an activity of an acquiree or to terminate or relocate an acquiree’s employees are not liabilities at the acquisition date but must be expensed in accordance with other applicable generally accepted accounting principles. If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the acquirer must report in its financial statements provisional amounts for the items for which the accounting is incomplete. During the measurement period, which must not exceed one year from the acquisition date the acquirer will retrospectively adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. The acquirer will be required to expense all acquisition-related costs in the periods such costs are incurred other than costs to issue debt or equity securities. SFAS No. 141(R) will not have an impact on our consolidated financial position, results of operations or cash flows at the date of adoption, but it could have a material impact on our consolidated financial position, results of operations or cash flows in the future when it is applied to acquisitions which occur in 2009 and beyond.

On January 1, 2008, we adopted EITF IssueNo. 06-11, “Accounting for Income Tax Benefits of Dividends on Share-Based Payment Awards.”EITF 06-11 requires that a realized income tax benefit from dividends or dividend equivalent units paid on unvested restricted shares and restricted share units be reflected as an increase in contributed surplus and reflected as an addition to the Company’s excess tax benefit pool, as defined under SFAS No. 123(R). Because we did not declare any dividends during the first quarter of 2008, and do not currently anticipate declaring dividends in the near future,EITF 06-11 did not have any impact during the first quarter of 2008, and is not expected to have a material impact in the near term, on our consolidated financial position, results of operations or cash flows.

In December 2007, the Securities & Exchange Commission (SEC) published Staff Accounting Bulletin No. 110 (SAB 110). SAB 110 expresses the views of the SEC staff regarding the use of a “simplified” method, as discussed in SAB No. 107 (SAB 107), in developing an estimate of expected term of “plain vanilla” share options in accordance with SFAS No. 123(R). In particular, the SEC staff indicated in SAB 107 that it will accept a company’s election to use the simplified method, regardless of whether the company has sufficient information to make more refined estimates of expected term. However, the SEC staff stated in SAB 107 that it would not expect a company to use the simplified method for share option grants after December 31, 2007. In SAB 110, the SEC staff states that they will continue to accept, under certain circumstances, the use of the simplified method beyond December 31, 2007. Because we currently do not anticipate issuing stock options in the near future, SAB 110 is not anticipated to have a material impact on our consolidated financial position, results of operations or cash flows in the near term.

In March 2008, the FASB issued SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities — An Amendment of FASB No. 133.” SFAS No. 161 requires enhanced disclosures to enable investors to better understand how a reporting entity’s derivative instruments and hedging activities impact the entity’s financial position, financial performance and cash flows. SFAS No. 161 is effective for financial statements issued after November 15, 2008, including interim financial statements. Early application is encouraged. Since we do not currently have any derivatives or hedging activities, SFAS No. 161 is not anticipated to have a material impact on our consolidated financial position, results of operations, cash flows or disclosures.

Outlook

The following statements are based on our current expectations and beliefs. These statements are forward-looking, and actual results may differ materially.

Many utilities across the country have increased or are planning to increase spending on their transmission and distribution systems. As a result, we are seeing new construction, extensive pole change-outs, line upgrades and maintenance projects on many systems and expect this trend to continue over the next several quarters.

We also anticipate increased spending over the next decade as a result of the Energy Policy Act of 2005 (the Energy Act), which requires the power industry to meet federal reliability standards for its transmission and distribution systems and provides further incentives to the industry to invest in and improve maintenance on its systems, although rule-making initiatives under the Energy Act could be impacted, both in timing and in scope, by a new presidential administration. Additionally, we expect renewable energy mandates to result in the need for additional transmission lines and substations resulting from the construction of solar and wind electric generating power plants. As a result of these and other factors, we expect a continued shift in our services mix to a greater proportion of high-voltage electric power transmission and substation projects over the long term, as well as opportunities to provide installation services for renewable projects.

Several industry and market trends are also prompting customers in the electric power industry to seek outsourcing partners, such as us. These trends include an aging utility workforce, increased spending, increasing costs and labor issues. The need to ensure available labor resources for larger projects is also driving strategic relationships with customers.

In the telecommunications industry, there are several initiatives currently underway by several wireline carriers and government organizations that provide us with opportunities, in particular initiatives for fiber to the premises (FTTP) and fiber to the node (FTTN). Such initiatives are underway by Verizon and AT&T, and municipalities and other government jurisdictions have also become active in these initiatives. We are also experiencing increased spending by wireless telecommunications customers on their networks, as the impact of mergers within the wireless industry has begun to lessen. In addition, several wireless companies have announced plans to increase their cell site deployment plans over the next year, including the expansion of next generation technology.

Spending in the cable television industry is beginning to improve. Several telecommunications companies are increasing the pace of their FTTP and FTTN projects that will enable them to offer TV services via fiber to their customers. We anticipate that these initiatives will serve as a catalyst for the cable industry to begin a new network upgrade cycle to expand its service offerings in an effort to retain and attract customers.

Our dark fiber leasing business is also experiencing growth primarily through the expansion into additional geographic markets, with a focus within those markets on education and healthcare customers where secure high-speed networks are important. We continue to see opportunities for growth both in the markets we currently serve and new markets. To support the growth in this business, we anticipate continued increased capital expenditures.

Gas distribution installation services are driven in part by the housing construction market. Our gas operations have been impacted by recent declines in new housing construction in certain sectors of the country. While these operations have been challenged by lower margins overall, we are taking steps to improve margins, including eliminating certain low margin contracts and focusing more on natural gas gathering pipeline construction and other more profitable services and less on residential housing projects.

Historically, our customers have continued to spend through short-term economic softness or weak recessions. A long-term or deep recession, however, would likely have some negative impact on our customers’ spending. Lower spending may not automatically mean less revenue for us, as utilities continue outsourcing more of their work, in part due to their aging workforce issues. We believe that we remain the partner of choice for many utilities in need of broad infrastructure expertise, specialty equipment and workforce resources. Furthermore, as new technologies emerge for communications and digital services such as voice, video and data continue to converge, telecommunications and cable service providers are expected to work quickly to deploy fast, next-generation fiber networks, and we are recognized as a key partner in deploying these services.

On August 30, 2007, we consummated the Merger with InfraSource, which enhances our resources and expands our service portfolio through InfraSource’s complementary businesses, strategic geographic footprint and skilled workforce. We have already begun to realize the benefits of the Merger through additional opportunities, and we continue to expect that the combined company will be able to better serve our customers as demand grows in their respective industries.

We continue to evaluate other potential strategic acquisitions of companies to broaden our customer base, expand our geographic area of operation and grow our portfolio of services. We believe that additional attractive acquisition candidates exist primarily as a result of the highly fragmented nature of the industry, the inability of many companies to expand and modernize due to capital constraints and the desire of owners of acquisition candidates for liquidity. We also believe that our financial strength and experienced management team will be attractive to acquisition candidates.

With the growth in several of our markets and our margin enhancement initiatives, we continue to see our gross margins generally improve. We continue to focus on the elements of the business we can control, including cost control, the margins we accept on projects, collecting receivables, ensuring quality service and rightsizing initiatives to match the markets we serve. These initiatives include aligning our workforce with our current revenue base, evaluating opportunities to reduce the number of field offices and evaluating our non-core assets for potential sale. Such initiatives, together with realignments associated with the ongoing integration of InfraSource operations and any other future acquisitions, could result in future charges related to, among other things, severance, retention, the shutdown and consolidation of facilities, property disposal and other exit costs.

Capital expenditures in 2008 are expected to be approximately $195 million. Approximately $85 million of the expenditures is targeted for dark fiber expansion and the majority of the remaining expenditures will be for operating equipment in the Infrastructure Services segment. We expect expenditures for 2008 to be funded substantially through internal cash flows, or to the extent necessary, from cash on hand.

We believe that we are adequately positioned to capitalize upon opportunities and trends in the industries we serve because of our proven full-service operating units with broad geographic reach, financial capability and technical expertise. Our acquisition of InfraSource further enhanced these strengths. Additionally, we believe that these industry opportunities and trends will increase the demand for our services; however, we cannot predict the actual timing or magnitude of the impact on us of these opportunities and trends.

Item 3.	*Quantitative and Qualitative Disclosures About Market Risk.*

The information in this section should be read in connection with the information on financial market risk related to changes in fuel prices, interest rates and currency exchange rates in Part II, Item 7A, Quantitative and Qualitative Disclosures About Market Risk, in our Annual Report onForm 10-K for the year ended December 31, 2007. Our primary exposure to market risk relates to unfavorable changes in fuel prices, interest rates and currency exchange rates. We are currently not exposed to any significant market risks or interest rate risk from the use of derivatives.

Interest Rate. Our exposure to market rate risk for changes in interest rates relates to our convertible subordinated notes. The fair market value of our fixed rate convertible subordinated notes is subject to interest rate risk and market risk due to the convertible feature of our convertible subordinated notes. Generally, the fair market value of fixed interest rate debt will increase as interest rates fall and decrease as interest rates rise. The fair market value of our convertible subordinated notes will also increase as the market price of our stock increases and decrease

as the market price falls. The interest and market value changes affect the fair market value of our convertible subordinated notes but do not impact their carrying value. As of December 31, 2007 and March 31, 2008, the fair value of our fixed-rate debt of $413.8 million and $413.8 million was approximately $825.6 million and $761.4 million, based upon market prices on or before such date.

Currency Risk. The business of our Canadian subsidiaries is subject to currency fluctuations. We do not expect any such currency risk to be material.


Item 4.	*Controls and Procedures.*

Attached as exhibits to this quarterly report onForm 10-Q are certifications of Quanta’s Chief Executive Officer and Chief Financial Officer that are required in accordance withRule 13a-14 of the Securities Exchange Act of 1934, as amended (the Exchange Act). This “Controls and Procedures” section includes information concerning the controls and controls evaluation referred to in the certifications, and it should be read in conjunction with the certifications for a more complete understanding of the topics presented.

Evaluation of Disclosure Controls and Procedures

Our management has established and maintains a system of disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act, such as this quarterly report, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. The disclosure controls and procedures are also designed to provide reasonable assurance that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

As of the end of the period covered by this quarterly report, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant toRule 13a-15(b) of the Exchange Act. This evaluation was carried out under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer. Based on this evaluation, these officers have concluded that, as of March 31, 2008, our disclosure controls and procedures were effective to provide reasonable assurance of achieving their objectives.

Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting during the quarter ended March 31, 2008, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Design and Operation of Control Systems

Our management, including the Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and breakdowns can occur because of simple errors or mistakes. Controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

PART II — OTHER INFORMATION

QUANTA SERVICES, INC. AND SUBSIDIARIES


Item 1.	*Legal Proceedings.*

InfraSource, certain of its officers and directors and various other parties, including David R. Helwig, the former chief executive officer of InfraSource who became a director of Quanta after completion of the Merger, were defendants in a lawsuit seeking unspecified damages filed in the State District Court in Harris County, Texas on September 21, 2005. The plaintiffs alleged that the defendants violated their fiduciary duties and committed constructive fraud by failing to maximize shareholder value in connection with certain acquisitions by InfraSource Incorporated that closed in 1999 and 2000 and the acquisition of InfraSource Incorporated by InfraSource in 2003 and committed other acts of misconduct following the filing of the petition. The parties to this litigation settled the material claims in January 2008 and the lawsuit was dismissed by the court on March 4, 2008. The amount of the settlement was reserved in 2007, and therefore the payment of the settlement amount had no impact on our results of operations for the first quarter of 2008.

We are from time to time a party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, breach of contractand/or property damages, punitive damages, civil penalties or other losses, or injunctive or declaratory relief. With respect to all such lawsuits, claims and proceedings, we record reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. We do not believe that any of these proceedings, separately or in the aggregate, would be expected to have a material adverse effect on our financial position, results of operations or cash flows.


Item 1A.	*Risk Factors.*

As of the date of this filing, there have been no material changes from the risk factors previously disclosed in Item 1A to Part I of our Annual Report onForm 10-K for the year ended December 31, 2007 (2007 Annual Report). An investment in our common stock involves various risks. When considering an investment in our company, you should carefully consider all of the risk factors described in our 2007 Annual Report. These risks and uncertainties are not the only ones facing us and there may be additional matters that are not known to us or that we currently consider immaterial. All of these risks and uncertainties could adversely affect our business, financial condition or future results and, thus, the value of an investment in our company.
