NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
| 1. | BUSINESS AND ORGANIZATION: | 
    Quanta Services, Inc. (Quanta) is a leading provider of
    specialized contracting services, offering
    end-to-end
    network solutions to the electric power, gas, telecommunications
    and cable television industries. Quantas comprehensive
    services include designing, installing, repairing and
    maintaining network infrastructure.
    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 Quantas Annual Report on
    Form 10-K
    for the year ended December 31, 2005, which was filed with
    the SEC on March 2, 2006.
    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 based on
    Quantas 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 Quantas assessment of the allowance
    for doubtful accounts, valuation of inventory, useful lives of
    property and equipment, fair value assumptions in analyzing
    goodwill and long-lived asset impairments, self-insured claims
    liabilities, revenue recognition under
    percentage-of-completion
    accounting and provision for income taxes.
    Short-Term
    Investments
    Quanta invests a portion of its cash in variable rate demand
    notes (VRDNs), which are classified as short-term investments.
    The income from these VRDNs is tax-exempt to Quanta. The
    interest rates on these instruments are variable and reset daily
    or weekly, depending on the security. As a result of the reset
    feature, Quanta continually earns the market interest rate.
    While VRDNs are debt instruments with scheduled maturities
    ranging from 10-30 years, Quanta has the right to tender the
    securities to a third-party liquidity provider for payment at
    the aggregate principal amount plus accrued interest at any time
    with seven days notice pursuant to the put right granted to all
    holders of these notes. Payment of these notes is secured by an
    irrevocable letter of credit issued by an investment-grade
    financial institution. Due to the liquidity and the short-term
    nature of Quantas investment in these securities, they
    have been classified as current assets in its condensed
    consolidated balance sheets and are classified as available for
    sale. These securities are carried at the aggregate principal
    amount, which approximates fair value, resulting in no
    unrealized gain (loss) to be recorded in other comprehensive
    income.

    Current
    and Long-Term Accounts and Notes Receivable and Allowance
    for Doubtful Accounts
    Quanta provides an allowance for doubtful accounts when
    collection of an account or note receivable is considered
    doubtful. Inherent in the assessment of the allowance for
    doubtful accounts are certain judgments and estimates including,
    among others, the customers access to capital, the
    customers 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. As of
    September 30, 2006, Quanta has provided allowances for
    doubtful accounts of approximately $48.6 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. In
    addition, material changes in Quantas customers
    revenues or cash flows could affect its ability to collect
    amounts due from them.
    Included in accounts and notes receivable are amounts due from a
    customer relating to the construction of independent power
    plants. During the first quarter of 2006, the underlying assets
    which had secured these notes receivable were sold pursuant to
    liquidation proceedings and the net proceeds are being held by a
    trustee. The final collection of amounts owed to Quanta are
    subject to further legal proceedings. Quanta has provided
    allowances for a significant portion of these notes receivable.
    Also included in accounts and notes receivable are
    $5.0 million in retainage balances with settlement dates
    beyond the next twelve months.
    During 2004, Quanta sold its prepetition receivable due from
    Adelphia Communications Corporation and its affiliated companies
    (Adelphia) to a third party with $6.0 million of the
    proceeds held by the buyer pending the resolution of certain
    preferential payment claims. During the third quarter of 2006,
    the preferential payment claims were settled and Quanta
    collected the $6.0 million.
    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,
    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. No customer accounted for more
    than 10% of accounts receivable as of December 31, 2005 and
    September 30, 2006 or revenues for the three and nine
    months ended September 30, 2005 and 2006.
    Goodwill
    and Other Intangibles
    In accordance with Statement of Financial Accounting Standards
    (SFAS) No. 142, Goodwill and Other Intangible
    Assets, goodwill attributable to each of Quantas
    reporting units is tested for impairment by comparing the fair
    value of each reporting unit with its carrying value. Fair value
    is determined using a combination of the discounted cash flow,
    market multiple and market capitalization valuation approaches.
    Significant estimates used in the above methodologies include
    estimates of future cash flows, future short-term and long-term
    growth rates, weighted average cost of capital and estimates of
    market multiples for each of the reporting units. On an ongoing
    basis, absent impairment indicators, Quanta performs impairment
    tests annually during the fourth quarter. SFAS No. 142
    does not allow increases in the carrying value of reporting
    units that may result from Quantas impairment test,
    therefore Quanta may record goodwill impairments in the future,
    even when the aggregate fair value of Quantas reporting
    units and Quanta as a whole may increase. Any future impairment
    adjustments would be recognized as operating expenses.

    Income
    Taxes
    Quanta follows the liability method of accounting for income
    taxes in accordance with SFAS No. 109,
    Accounting for Income Taxes. Under this method,
    deferred 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,
    and Quanta maintains an allowance for tax contingencies that
    Quanta believes is adequate. 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.
    New
    Accounting Pronouncements
    In February 2006, the Financial Accounting Standards Board
    (FASB) issued SFAS No. 155, Accounting for
    Certain Hybrid Financial Instruments  An Amendment of
    FASB Statements No. 133 and 140.
    SFAS No. 155 provides entities with relief from having
    to separately determine the fair value of an embedded derivative
    that would otherwise be required to be bifurcated from its host
    contract in accordance with SFAS No. 133.
    SFAS No. 155 allows an entity to make an irrevocable
    election to measure such a hybrid financial instrument at fair
    value in its entirety, with changes in fair value recognized in
    earnings. SFAS No. 155 is effective for all financial
    instruments acquired, issued or subject to a remeasurement event
    occurring after the beginning of an entitys first fiscal
    year that begins after September 15, 2006. Quanta does not
    have any financial instruments that fall under the scope of this
    statement and does not believe that the adoption of
    SFAS No. 155 will have a material impact on
    Quantas financial position, results of operations or cash
    flows.
    In June 2006, the FASB issued Interpretation (FIN) No. 48,
    Accounting for Uncertainty in Income Taxes  An
    Interpretation of FASB Statement 109.
    FIN No. 48 prescribes a comprehensive model for
    recognizing, measuring, presenting and disclosing uncertain tax
    positions within financial statements. The provisions of
    FIN No. 48 are effective for fiscal years beginning
    after December 15, 2006. Quanta is currently analyzing the
    provisions of FIN No. 48 and has not yet made a
    determination of the impact the adoption will have on its
    consolidated financial position, results of operations and cash
    flows.
    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. Quanta is currently analyzing the provisions of
    SFAS No. 157 and determining how it will affect
    accounting policies and procedures and has not yet made a
    determination of the impact the adoption will have on its
    consolidated financial position, results of operations and cash
    flows.
    In September 2006, the SEC issued Staff Accounting
    Bulletin No. 108, Considering the Effects of
    Prior Year Misstatements when Quantifying Misstatements in
    Current Year Financial Statements (SAB 108), which
    provides guidance on the consideration of the effects of prior
    year misstatements in quantifying current year misstatements for
    the purpose of a materiality assessment. SAB 108 requires
    that the materiality of the effect of a misstated amount be
    evaluated on each financial statement and the related financial
    statement disclosures, and that materiality evaluation be based
    on quantitative and qualitative factors. SAB 108 is
    effective for fiscal years beginning after November 15,
    2006. Quanta does not believe this guidance will have a material
    impact on Quantas financial position, results of
    operations or cash flows.

| 2. | 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 they are granted. The resulting
    compensation cost is recognized over the service period of each
    award. In accordance with the modified prospective method of
    adoption, Quanta has not adjusted consolidated financial
    statements for prior periods.
    Prior to January 1, 2006, Quanta accounted for its
    stock-based compensation awards under APB Opinion No. 25,
    Accounting for Stock Issued to Employees. Under this
    accounting method, no compensation expense was recognized in the
    consolidated statements of operations if no intrinsic value of
    the stock-based compensation award existed at the date of grant.
    SFAS No. 123, Accounting for Stock Based
    Compensation, which encouraged companies to account for
    stock-based compensation awards based on the fair value of the
    awards at the date they were granted, required disclosure as to
    what net income and earnings per share would have been had
    SFAS No. 123 been followed. Had compensation expense
    for the 2001 Stock Incentive Plan (as amended and restated
    March 31, 2003) (the 2001 Plan) and the Employee Stock
    Purchase Plan, which was terminated in 2005, been determined
    consistent with SFAS No. 123, Quantas net income
    and earnings per share for the three and nine months ended
    September 30, 2005 would have been reduced to the following

    Beginning January 1, 2006, Quanta accounted for its stock
    options in accordance with SFAS No. 123(R); however,
    the effect of expensing the fair value of the stock options did
    not have a material impact on Quantas financial position
    or results of operations, as the number of unvested stock
    options remaining is not significant. Certain disclosures
    required under SFAS No. 123(R) have been omitted due
    to immateriality.
    The actual tax benefit realized for the tax deductions from
    option exercises totaled approximately $0.1 million for the
    three months ended September 30, 2006 and $0.4 million
    for the nine months ended September 30, 2006. This tax
    benefit is reported as a cash inflow from financing activities
    and an adjustment to net income to derive cash flow from
    operations within the statement of cash flows for the three and
    nine months ended September 30, 2006, as

    periods have not been adjusted in accordance with the modified
    prospective method of application.
    Restricted
    Stock
    During 2003, Quanta began using restricted stock rather than
    stock options for Quantas various stock incentive
    programs. Pursuant to the 2001 Plan, Quanta issues 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 pursuant to the 2001 Plan 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 plan
    participants are entitled to vote and receive dividends on such
    shares. During the three months ended September 30, 2005
    and 2006, Quanta granted 3,530 and 6,694 shares of
    restricted stock with a weighted average grant price of $11.33
    and $17.18. During each of the nine months ended
    September 30, 2005 and 2006, Quanta granted approximately
    0.7 million shares of restricted stock with a weighted
    average grant price of $7.57 and $13.92. During the three months
    ended September 30, 2005 and 2006, 7,051 and
    8,228 shares vested with an approximate fair value of
    $0.1 million and $0.1 million. Approximately
    1.0 million and 1.2 million shares vested during the
    nine months ended September 30, 2005 and 2006 with an
    approximate total fair value of $8.4 million and
    $16.8 million. A summary of Quantas restricted stock
    activity for the nine months ended September 30, 2006 is as

    During the three months ended September 30, 2005 and 2006,
    Quanta recorded non-cash compensation expense with respect to
    restricted stock in the amount of $1.4 million and
    $1.6 million and a related income tax benefit of
    $0.6 million and $0.6 million. During the nine months
    ended September 30, 2005 and 2006, Quanta recorded non-cash
    compensation expense with respect to restricted stock in the
    amount of $3.6 million and $4.6 million and a related
    income tax benefit of $1.4 million and $1.8 million.
    The fair value of the restricted stock is determined based on
    the number of shares granted and the closing price of
    Quantas common stock on the date of grant. The adoption of
    SFAS No. 123(R)requires estimating future forfeitures
    in determining the period expense, rather than recording
    forfeitures when they occur as previously permitted. Quanta used
    historical data to estimate the forfeiture rate. The effect of
    estimating forfeitures in determining the period expense, rather
    than recording forfeitures as they actually occurred, was not
    significant.
    Total unrecognized compensation cost related to unvested
    restricted stock granted to both employees and non-employees was
    $11.4 million as of September 30, 2006. The
    unrecognized compensation cost is expected to be recognized over
    a weighted-average period of 1.8 years. The estimate of
    unrecognized compensation cost uses the expected forfeiture
    rate, and to the extent that Quanta revises that estimate in the
    future, the estimate may not necessarily represent the value
    that will ultimately be realized as compensation expense. As of
    December 31, 2005, unrecognized compensation expense
    related to unvested shares of restricted stock granted to
    employees was recorded as deferred compensation in
    stockholders equity. As part of the adoption of
    SFAS No. 123(R), $6.4 million of deferred
    compensation was reversed against additional paid-in capital
    during the first quarter of 2006.

    inclusion of such stock options and shares would be antidilutive

    months ended September 30, 2005 and 2006, as the
    options exercise prices were greater than the average
    market price of Quantas common stock. The effect of
    assuming conversion of the 4.0% convertible subordinated
    notes would be antidilutive for all periods presented and the
    shares issuable upon conversion were therefore excluded from the
    computation of diluted earnings per share. The effect of
    assuming conversion of the 3.75% convertible subordinated
    notes would be antidilutive for the nine months ended
    September 30, 2006, and the shares issuable upon conversion
    were therefore excluded from the computation of diluted earnings
    per share. The effect of assuming conversion of the
    4.5% convertible subordinated notes would be antidilutive
    for the nine months ended September 30, 2005, and the
    shares issuable upon conversion were therefore excluded from the
    computation of diluted earnings per share.

    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
    amount of the credit facility is available for the issuance of
    letters of credit.
    As of September 30, 2006, Quanta had approximately
    $125.4 million of letters of credit issued under the credit
    facility and no outstanding revolving loans. The remaining
    $174.6 million was available for revolving loans or issuing

    facility bear interest, at Quantas option, at a rate equal
    to either (a) the Eurodollar Rate (as defined in the credit
    facility) plus 1.25% to 1.875%, as determined by the ratio of
    Quantas total funded debt to consolidated EBITDA (as

    described below) plus 0.25% to 0.875%, as determined by the
    ratio of Quantas total funded debt to consolidated EBITDA.
    Letters of credit issued under the credit facility are subject
    to a letter of credit fee of 1.25% to 1.875%, based on the ratio
    of Quantas total funded debt to consolidated EBITDA.
    Quanta is also subject to a commitment fee of 0.25% 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) plus 1/2 of 1% and
    (ii) the banks 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, minimum
    interest coverage and minimum consolidated net worth, 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,
    Quantas 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 September 30, 2006, 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 to an annual aggregate
    amount of up to 25% of Quantas consolidated net income
    (plus the amount of non-cash charges that reduced such
    consolidated net income) for the prior fiscal year. The credit
    facility does not limit dividend 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 Quantas existing subordinated
    notes, its continuing indemnity and security agreement with its
    surety and all of its other debt instruments exceeding
    $10.0 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 Quantas U.S. subsidiaries, 65% of the
    capital stock of its foreign subsidiaries and substantially all
    of Quantas assets. Quantas U.S. subsidiaries
    guarantee the repayment of all amounts due under the credit
    facility. Quantas obligations under the credit facility
    constitute designated senior indebtedness under its 3.75%, 4.0%
    and 4.5% convertible subordinated notes.
    As of December 31, 2005, Quanta had a $182.0 million
    credit facility with various lenders (the prior facility). The
    prior facility was amended during the second quarter of 2006 to
    permit, among other things, Quantas cash tender offer for
    its 4.0% convertible subordinated notes and Quantas
    issuance of its 3.75% convertible subordinated notes, each
    as described below. Upon the amendment and restatement of
    Quantas credit facility, the obligations under the prior
    facility were terminated, and related unamortized debt issuance
    costs in the amount of approximately $2.6 million were
    expensed in the second quarter of 2006 and included in interest
    expense. As of December 31, 2005, Quanta had approximately
    $142.6 million of letters of credit outstanding under the
    prior facility and $7.5 million of the letter of credit
    facility outstanding as a term loan.

    4.0% Convertible
    Subordinated Notes
    As of September 30, 2006, Quanta had $33.3 million
    aggregate principal amount of 4.0% convertible subordinated
    notes (4.0% Notes) outstanding, which was classified as a
    current obligation as these 4.0% Notes will mature within
    the next twelve months. The credit facility permits the
    repayment of these 4.0% Notes on or before maturity at
    Quantas sole discretion. The 4.0% Notes are
    convertible into shares of Quantas common stock at a price
    of $54.53 per share, subject to adjustment as a result of
    certain events. The sale of the notes and the shares issuable
    upon conversion thereof was registered by Quanta in a
    registration statement filed with the SEC. The 4.0% Notes
    require semi-annual interest payments on July 1 and
    December 31 until the notes mature on July 1, 2007.
    Quanta has the option to redeem some or all of the
    4.0% Notes at specified redemption prices, together with
    accrued and unpaid interest. If certain fundamental changes
    occur, as described in the indenture under which Quanta issued
    the 4.0% Notes, holders of the 4.0% Notes may require
    Quanta to purchase all or part of the notes at a purchase price
    equal to 100% of the principal amount, plus accrued and unpaid
    interest. During the second quarter of 2006, Quanta conducted a
    cash tender offer for all of the 4.0% Notes, which resulted
    in the repurchase of $139.2 million of the 4.0% Notes.
    As a result of the repurchase of a portion of the
    4.0% Notes, Quanta recorded a gain on early extinguishment
    of debt of approximately $2.1 million, during the second
    quarter of 2006, which was partially offset by costs associated
    with the tender offer of approximately $0.5 million. In
    addition, approximately $0.7 million in related unamortized
    debt issuance costs associated with the retirement of a portion
    of the tendered 4.0% Notes has been expensed and included
    in interest expense.
    4.5% Convertible
    Subordinated Notes
    As of September 30, 2006, Quanta had $270.0 million
    aggregate principal amount of 4.5% convertible subordinated
    notes (4.5% Notes) outstanding. 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 Quantas
    common stock based on an initial conversion rate of
    89.7989 shares of Quantas 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
    Quantas 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
    Quantas 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
    Quantas 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. During the three
    months ended September 30, 2006, the market price condition
    described in clause (i) above was satisfied, and the notes
    are presently convertible at the option of each holder. The
    conversion period will expire on December 31, 2006, but may
    resume upon the satisfaction of the market condition or other
    conditions in future periods.
    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
    the notes at the principal amount thereof plus accrued and
    unpaid interest on October 1, 2008, 2013 or 2018, or upon
    the occurrence of a fundamental change, as defined by the
    indenture. 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. Quanta presently does not anticipate
    using stock to satisfy any future obligations. If Quanta were to

    dollar amount to be paid in common stock divided by 98.5% of the
    market price of Quantas common stock, as defined by the
    indenture. The number of shares to be issued under this
    circumstance is not limited. The right to settle for shares of
    common stock can be surrendered by Quanta. The 4.5% Notes
    carry cross-default provisions with Quantas other debt
    instruments exceeding $10.0 million in borrowings, which
    includes Quantas existing credit facility.
    3.75% Convertible
    Subordinated Notes
    As of September 30, 2006, Quanta had $143.8 million
    aggregate principal amount of 3.75% convertible
    subordinated notes due 2026 (3.75% Notes) outstanding. 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 which Quanta filed with the SEC during
    the third quarter 2006. 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, commencing on October 30, 2006.
    The 3.75% Notes are convertible into Quantas common
    stock, based on an initial conversion rate of
    44.6229 shares of Quantas 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 Quantas 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 Quantas 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.
    If the 3.75% Notes become convertible under any of these
    circumstances, Quanta has the option to deliver cash, shares of
    Quantas 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 Quantas
    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 would 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 Quantas other debt instruments exceeding
    $20.0 million in borrowings, which includes Quantas
    existing credit facility.

    Deferred
    Compensation
    Prior to the adoption of SFAS No. 123(R), upon
    issuance of the restricted stock pursuant to the 2001 Plan, an
    unamortized compensation expense equivalent to the market value
    of the shares on the date of grant was charged to
    stockholders equity as deferred compensation and amortized
    over the restriction period as non-cash compensation expense.
    Effective with the adoption of SFAS No. 123(R),
    deferred compensation is no longer recorded and the amount
    recorded as of December 31, 2005, $6.4 million, was

    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 nine months of 2006, Quanta withheld

    Litigation
    Quanta is 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 contract
    and/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 Quantas financial position, results of operations or
    cash flows.
    Self-Insurance
    As of September 30, 2006, Quanta is insured for
    employers liability and general liability claims, subject
    to a deductible of $1.0 million per occurrence, and for
    auto liability and workers compensation claims, subject to
    a deductible of $2.0 million per occurrence. In addition,
    beginning August 1, 2006, Quanta is subject to an
    additional cumulative aggregate liability of up to
    $2.0 million on workers compensation claims in excess
    of $2.0 million per occurrence per policy year. Quanta also
    has an employee health care benefits plan for employees not
    subject to collective bargaining agreements, which is subject to
    a deductible of $250,000 per claimant per year. Losses are
    accrued based upon Quantas estimates of the ultimate
    liability for claims incurred and an estimate of claims incurred
    but not reported, with assistance from a third-party actuary.
    The accruals are based upon known facts and historical trends
    and management believes such accruals to be adequate. As of
    December 31, 2005 and September 30, 2006, the gross
    amount accrued for self-insurance claims totaled
    $99.5 million and $106.9 million, with
    $64.4 million and $66.4 million considered to be
    long-term and included in other non-current liabilities. Related
    insurance recoveries/receivables as of December 31, 2005
    and September 30, 2006 were $6.3 million and
    $6.4 million, of which $3.3 million and
    $1.2 million are included in prepaid expenses and other
    current assets and $3.0 million and $5.2 million are
    included in other assets, net.
    Quantas casualty insurance carrier for the policy periods
    from August 1, 2000 to February 28, 2003 is
    experiencing financial distress but is currently paying valid
    claims. In the event that this insurers financial
    situation 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 Quantas behalf
    for the above-mentioned policy periods is approximately
    $4.5 million, and Quanta has recorded a receivable and
    corresponding liability for such amount as of September 30,
    2006. However, Quantas estimate of the potential range of
    these future claim amounts is between $3.0 million and
    $9.5 million. The actual amounts ultimately paid by Quanta
    related to these 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 Quanta, or any
    alternative actions Quanta may pursue, to have a material
    adverse impact on Quantas financial condition; however,
    the impact could be material to Quantas results of
    operations or cash flows in a given period.
    Performance
    Bonds
    In certain circumstances, Quanta is required to provide
    performance bonds in connection with its contractual
    commitments. Quanta has indemnified the surety for any expenses
    paid out under these performance bonds. As of September 30,
    2006, the total amount of outstanding performance bonds was
    approximately $568.6 million.

    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
    September 30, 2006, the maximum guaranteed residual value
    was approximately $102.9 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 future significant payments will not be required.
    As of September 30, 2006, Quanta had capital lease
    obligations of $0.3 million included within current
    maturities of long-term debt.
    Employment
    Agreements
    Quanta has entered into various employment agreements with
    certain executives which provide for compensation and certain
    other benefits and for severance payments under certain
    circumstances. In addition, certain employment agreements
    contain clauses that become effective upon a change of control
    of Quanta. 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
    employees responsibility.
    Collective
    Bargaining Agreements
    Certain of the 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.
    Income
    Tax Audits
    Quanta has received federal tax refunds in the amounts of
    $38.1 million in 2003 and $30.2 million in 2004 from
    the Internal Revenue Service (IRS) due to the carry-back of
    taxable losses reported on Quantas 2002 and 2003 income
    tax returns. The IRS is required by law to review Quantas
    refund claims. As a result, Quanta is currently

    NOTES TO
    CONDENSED CONSOLIDATED FINANCIAL
    STATEMENTS  (Continued)
    under audit for tax years 2000 through 2004. Quanta fully
    cooperates with all audits, but defends existing positions
    vigorously. To provide for potential tax exposures, Quanta
    maintains an allowance for tax contingencies, which management
    believes is adequate. As of December 31, 2005 and
    September 30, 2006, the amounts accrued for tax
    contingencies totaled $67.5 million and $74.9 million,
    with $46.8 and $53.2 million considered to be long-term and
    included in other non-current liabilities. The results of future
    audit assessments, if any, could have a material effect on
    Quantas cash flows during the periods in which these
    audits are settled. However, management does not believe that
    any of these matters will have a material adverse effect on
    Quantas consolidated results of operations.
    Indemnities
    Quanta has indemnified various parties against specified
    liabilities that those parties might incur in the future in
    connection with Quantas previous acquisitions of certain
    companies. These indemnities usually are contingent upon the
    other party incurring liabilities that reach specified
    thresholds. As of September 30, 2006, Quanta is not aware
    of circumstances that would lead to future indemnity claims
    against it for material amounts in connection with these
    transactions.

| Item 2. | Managements 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 on
    Form 10-Q
    and with our Annual Report on
    Form 10-K,
    which was filed with the SEC on March 2, 2006 and is
    available on the SECs website at www.sec.gov. 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 in Uncertainty of
    Forward-Looking Statements and Information.
    Introduction
    We are a leading national provider of specialty contracting
    services, offering
    end-to-end
    network solutions to the electric power, gas,
    telecommunications, cable television and specialty services
    industries. We believe that we are the largest contractor
    servicing the transmission and distribution sector of the North
    American electric utility industry. We derive our revenues from
    one reportable segment. Our customers include electric power,
    gas, telecommunications and cable television companies, as well
    as commercial, industrial and governmental entities. We had
    consolidated revenues for the nine months ended
    September 30, 2006 of approximately $1.5 billion, of
    which 65.3% was attributable to electric power and gas
    customers, 15.8% to telecommunications and cable television
    customers and 18.9% to 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.
    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. 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.
    Some of our customers require us to post performance and payment
    bonds upon execution of the contract, depending upon the nature
    of the work to be performed.
    We generally recognize revenue on our unit price and cost-plus
    contracts when units are completed or services are performed.
    For our fixed price contracts, we typically record revenues as
    work on the contract progresses on a
    percentage-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.
    Seasonality;
    Fluctuations of Results
    Our revenues and results of operations can be subject to
    seasonal variations. These variations are influenced by weather,
    customer spending patterns, bidding seasons 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.
    Additionally, our industry can be highly cyclical. As a result,
    our volume of business may be adversely affected by declines in
    new projects in various geographic regions in the United States.
    The financial condition of our
    
    18
Table of Contents
    customers and their access to capital, variations in the margins
    of projects performed during any particular quarter, regional
    economic conditions, timing of acquisitions and the timing and
    magnitude of acquisition assimilation costs 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 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 revenue and gross margin. In many
    cases, projects may be delayed or temporarily placed on hold due
    to inclement weather. 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, strong storms or
    hurricanes can provide us with high margin emergency service
    restoration work, which generally has a positive impact on
    margins.
    Revenue Mix.  The mix of revenue 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 revenue by industry served.
    Service and Maintenance versus
    Installation.  In general, installation work has a
    higher gross margin than maintenance work. This is because
    installation work is often obtained on a fixed price basis which
    has higher risk than other types of pricing arrangements. We
    typically derive approximately 50% of our revenue from
    maintenance work, which is performed under pre-established or
    negotiated prices or cost-plus pricing arrangements. Thus, a
    higher portion of installation work in a given quarter may
    result in a higher gross margin.
    Subcontract Work.  Work that is subcontracted
    to other service providers generally has 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%  15% of our work to other service
    providers.
    Materials versus Labor.  Margins may be lower
    on projects on which we furnish materials as material prices are
    generally more predictable than labor costs. Consequently, we
    generally are not able to mark up materials as much as 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 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 related to our deductibles in
    the period in which such adjustments are made. As of
    September 30, 2006, we had a deductible of
    $1.0 million per occurrence related to employers and
    general liability insurance and a deductible of
    $2.0 million per occurrence for automobile liability and
    workers compensation insurance. In addition, beginning
    August 1, 2006, we are subject to an additional cumulative
    aggregate liability of up to $2.0 million on workers
    compensation claims in excess of $2.0 million per occurrence per
    policy year. We also have an employee health care benefit plan
    for
    
    19
Table of Contents
    employees not subject to collective bargaining agreements, which
    is subject to a deductible of $250,000 per claimant per
    year.
    Selling,
    General and Administrative Expenses
    Selling, general and administrative expenses consist primarily
    of compensation and related benefits to management,
    administrative salaries and benefits, incentive bonuses,
    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.

    Three
    months ended September 30, 2006 compared to the three
    months ended September 30, 2005
    Revenues.  Revenues increased
    $5.1 million, or 1.0%, to $528.5 million for the three
    months ended September 30, 2006. Revenues for the third
    quarter of 2006 included a lower volume of emergency restoration
    services provided to our electric power and gas customers, as
    compared to the third quarter of 2005, which included the
    highest volume of emergency restoration services in our history
    in the wake of hurricanes in the Gulf Coast region of the United
    States. The total revenues associated with emergency restoration
    services in the third quarter of 2005 was approximately
    $74.2 million as compared to $16.1 million of
    emergency restoration services for the three months ended
    September 30, 2006. Excluding emergency restoration service
    revenues from both periods, revenues derived from the electric
    power and gas network services industry increased approximately
    $31.7 million, or 11.1%. Actual revenues derived from the
    electric power and gas network services industry, including
    emergency restoration services revenues, decreased approximately
    $25.6 million. Revenues from the telecommunications and
    cable television network services industry increased by
    approximately $17.8 million and revenues from ancillary
    services increased by $12.9 million for the three months
    ended September 30, 2006 compared to the three months ended
    September 30, 2005. The increase in these revenues is a
    result of a higher volume of work from increased spending by our
    customers resulting from the continued improving financial
    health of our customers and improved pricing.
    Gross profit.  Gross profit increased
    $3.0 million, or 3.7%, to $83.1 million for the three
    months ended September 30, 2006. As a percentage of
    revenues, gross margin increased from 15.3% for the three months
    ended
    
    20
Table of Contents
    September 30, 2005 to 15.7% for the three months ended
    September 30, 2006. Excluding the impact of storm
    restoration services from both periods, gross margins were
    higher in all of the primary industries we serve, due to
    continued strengthening market conditions. Inclusive of
    emergency restoration services, the gross margins from our
    electric power and gas network services customers decreased from
    the third quarter of 2005 due to the lower volume of higher
    margin emergency restoration services in the third quarter of
    2006.
    Selling, general and administrative
    expenses.  Selling, general and administrative
    expenses decreased $4.3 million, or 8.7%, to
    $45.1 million for the three months ended September 30,
    2006. As a percentage of revenues, selling, general and
    administrative expenses decreased from 9.4% to 8.5%. The
    $4.3 million decrease was primarily due to a decrease in
    professional fees in the amount of $3.8 million related to
    costs incurred for our margin enhancement program and for
    specific bidding activity in the third quarter of 2005 that were
    not incurred during the third quarter of 2006 as well as lower
    legal costs from ongoing litigation in the third quarter of
    2006. In addition, bad debt expense decreased approximately
    $1.3 million. These decreases were partially offset by
    slight increases in salaries and benefits costs.
    Interest expense.  Interest expense for the
    three months ended September 30, 2006 decreased
    $0.3 million as compared to the three months ended
    September 30, 2005, primarily due to a lower interest rate
    associated with our 3.75% convertible subordinated notes that
    were issued in the second quarter of 2006, the proceeds of which
    were used to repurchase a substantial portion of our 4.0%
    convertible subordinated notes during the second quarter of 2006.
    Interest income.  Interest income was
    $4.3 million for the three months ended September 30,
    2006 compared to $1.9 million for the three months ended
    September 30, 2005. The increase is primarily due to a
    higher average cash balance for the quarter ended
    September 30, 2006 as compared to the quarter ended
    September 30, 2005.
    Provision for income taxes.  The provision for
    income taxes was $14.2 million for the three months ended
    September 30, 2006, with an effective tax rate of 38.8%,
    compared to a provision of $13.8 million for the three
    months ended September 30, 2005, with an effective tax rate
    of 51.8%. During 2006, we have invested a portion of our
    available cash in tax-exempt investments as compared to 2005.
    Also, during the third quarter of 2006, we released
    approximately $0.4 million in state tax contingency
    reserves due to the expiration of various state statute periods.
    In addition, the lower effective tax rate for the three months
    ended September 30, 2006 results from higher projected
    income for the year ended 2006 as compared to projected income
    for the year ended 2005 and the impact of estimated
    non-deductible items on projected income.
    Nine
    months ended September 30, 2006 compared to the nine months
    ended September 30, 2005
    Revenues.  Revenues increased
    $203.9 million, or 15.3%, to $1.5 billion for the nine
    months ended September 30, 2006, with revenues derived from
    the electric power and gas network services industry increasing
    by approximately $100.1 million, revenues from the
    telecommunications and cable television network services
    industry increasing by approximately $44.9 million and
    revenues from ancillary services increasing by approximately
    $58.9 million. The increase in revenues is a result of a
    higher volume of work from increased spending by our customers
    resulting from their continued improving financial health,
    favorable weather conditions experienced during the first
    quarter and greater demand for all the primary services we
    offer. These increases were partially offset by a decrease of
    $53.5 million in emergency restoration service revenues for
    the nine months ended September 30, 2006 compared to the
    nine months ended September 20, 2005.
    Gross profit.  Gross profit increased
    $52.9 million, or 31.1%, to $222.9 million for the
    nine months ended September 30, 2006. As a percentage of
    revenues, gross margin increased from 12.7% for the nine months
    ended September 30, 2005 to 14.5% for the nine months ended
    September 30, 2006. The increase in margins for the nine
    months ended September 30, 2006 over the nine months ended
    September 30, 2005 is primarily attributable to higher
    margins on work from our electric power and gas network services
    customers and our telecommunications and cable television
    network services customers due to continued strengthening market
    conditions, improved pricing and our margin enhancement
    initiatives. Margins improved over the nine months ended
    September 30, 2006 on work from our electric power and gas
    network services customers despite the lower volume of higher
    margin emergency restoration services in the third quarter of
    2006 compared to the third quarter of 2005, as discussed above.
    In addition, during the first half of 2006, we achieved higher
    margins on certain jobs due to better
    
    21
Table of Contents
    productivity and cost control and relatively mild weather as
    compared to the first half of 2005, which was negatively
    impacted by cost overruns and weather delays on certain projects
    during the first quarter.
    Selling, general and administrative
    expenses.  Selling, general and administrative
    expenses decreased $1.7 million, or 1.3%, to
    $134.0 million for the nine months ended September 30,
    2006. As a percentage of revenues, selling, general and
    administrative expenses decreased from 10.1% to 8.7%. The
    $1.7 million decrease was due to a decrease in professional
    fees in the amount of $8.9 million related to costs
    incurred for our margin enhancement program and for specific
    bidding activity during the nine months ended September 30,
    2005 that were not incurred during the nine months ended
    September 30, 2006 as well as lower legal costs from
    ongoing litigation during the nine months ended
    September 30, 2006. In addition, we recorded bad debt
    expense of $1.8 million for the nine months ended
    September 30, 2005 compared to $0.9 million for the
    nine months ended September 30, 2006. These decreases were
    partially offset by a $7.6 million increase in salaries and
    benefits costs associated with increased personnel, costs of
    living adjustments and increased performance bonuses.
    Interest expense.  Interest expense for the
    nine months ended of September 30, 2006 increased
    $3.5 million as compared to the nine months ended
    September 30, 2005, primarily due to the expense of
    unamortized debt issuance costs of $3.3 million. We
    replaced our prior credit facility and expensed the remaining
    balance of unamortized debt issuance costs of $2.6 million.
    In addition, we expensed approximately 80.7%, or
    $0.7 million, of unamortized debt issuance costs related to
    the repurchase of 80.7% of our 4.0% convertible
    subordinated notes during the second quarter of 2006. The
    remaining increase in interest expense was due to a timing
    difference between the issuance of the 3.75% convertible
    subordinated notes during the second quarter of 2006 and use of
    those proceeds to affect the tender offer for the
    4.0% convertible subordinated notes later in the second
    quarter of 2006.
    Interest income.  Interest income was
    $10.3 million for the nine months ended September 30,
    2006, compared to $5.1 million for the nine months ended
    September 30, 2005. The increase in interest income
    primarily relates to a higher average cash balance for the nine
    months ended September 30, 2006 as compared to the nine
    months ended September 30, 2005. Included in these higher
    average cash balances is the effect of the timing difference
    between the issuance of the 3.75% convertible subordinated
    notes during the second quarter of 2006 and use of those
    proceeds to affect the tender offer for the
    4.0% convertible subordinated notes later in the second
    quarter of 2006.
    Provision for income taxes.  The provision for
    income taxes was $31.9 million for the nine months ended
    September 30, 2006, with an effective tax rate of 39.9%,
    compared to a provision of $10.7 million for the nine
    months ended September 30, 2005, with an effective tax rate
    of 49.2%. The lower effective tax rate for 2006 results from
    higher projected income for 2006 as compared to projected income
    for 2005 and the impact of estimated non-deductible items on
    projected income. Also, during 2006, we have invested a portion
    of our available cash in tax-exempt investments as compared to
    2005. In addition, we recorded a $1.6 million refund
    related to the settlement of a multi-year state tax claim during
    the second quarter of 2006.
    Liquidity
    and Capital Resources
    Cash
    Requirements
    We anticipate that our cash on hand and short-term investments,
    which together totaled $351.7 million as of
    September 30, 2006, the availability under our credit
    facility and our future cash flow from operations will be
    sufficient to enable us to meet our future operating needs, debt
    service requirements, and planned capital expenditures and to
    provide for our future ability to grow. We began to invest in
    variable rate demand notes during 2006. These instruments have
    long-term scheduled maturities, but provide the option to tender
    to a third-party liquidity provider at any time with seven days
    notice and are therefore classified as short-term investments.
    Momentum in deployment of fiber to the premises or initiatives
    to rebuild the United States electric power grid may require a
    significant amount of additional working capital. We also
    evaluate opportunities for strategic acquisitions from time to
    time that may require cash. However, we feel that we have
    adequate cash, short-term investments and availability under our
    credit facility to meet all such needs, although, depending on
    the size and number of any future acquisitions, we may need
    additional cash to fund one or more of those transactions.

    Sources
    and Uses of Cash
    As of September 30, 2006, we had cash and cash equivalents
    of $67.3 million, short-term investments of
    $284.4 million, working capital of $617.1 million and
    long-term debt of $413.8 million, net of current
    maturities. Our long-term debt balance at that date consists
    only of convertible subordinated notes. We also had
    $125.4 million of letters of credit outstanding under our
    credit facility.
    During the nine months ended September 30, 2006, operating
    activities provided net cash to us of $79.3 million. Cash
    flow from operations is primarily influenced by demand for our
    services, operating margins and the type of services we provide.
    We used net cash in investing activities of $313.8 million,
    including $284.4 million in net purchases of short-term
    investments and $36.2 million used for capital
    expenditures, offset by $6.9 million of proceeds from the
    sale of equipment. Financing activities used net cash flow of
    $2.5 million, resulting from $5.9 million in debt
    issuance costs and a $7.5 million repayment under the term
    loan portion of our prior credit facility, partially offset by
    $6.2 million in net borrowings primarily from the
    repurchase of our 4.0% convertible subordinated notes and
    the issuance of our 3.75% convertible subordinated notes as
    discussed below. Also contributing to cash from financing
    activities was $3.8 million in tax benefits from
    stock-based equity awards and $0.9 million received from
    the exercise of stock options.

    Instruments
    Credit
    Facility
    As of September 30, 2006, we had an amended and restated
    credit facility with various lenders which provides for a
    $300.0 million senior secured revolving credit facility
    maturing on June 12, 2011 (the credit facility). The credit
    facility amended and restated our prior credit facility. 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 amount of the credit facility is
    available for the issuance of letters of credit.
    As of September 30, 2006, we had approximately
    $125.4 million of letters of credit issued under the credit
    facility and no outstanding revolving loans. The remaining
    $174.6 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 1.25% to 1.875%, as determined by the ratio of our total
    funded debt to consolidated EBITDA (as defined in the credit
    agreement), or (b) the base rate (as described below) plus
    0.25% to 0.875%, 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 1.25%
    to 1.875%, based on the ratio of our total funded debt to
    consolidated EBITDA. We are also subject to a commitment fee of
    0.25% to 0.35%, based on the ratio of our 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) plus 1/2
    of 1% and (ii) the banks 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, minimum
    interest coverage and minimum consolidated net worth, 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
    September 30, 2006, we were in compliance with all of our
    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 to an annual aggregate
    amount of up to 25% of our consolidated net income (plus the
    amount of non-cash charges that reduced such consolidated net
    income) for the prior fiscal year. The credit facility does not
    limit dividend 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 surety and all of our other debt
    instruments exceeding $10.0 million in borrowings. If an
    
    23
Table of Contents
    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
    its 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%, 4.0% and 4.5% convertible subordinated notes.
    As of December 31, 2005, we had a $182.0 million
    credit facility with various lenders (the prior facility). The
    prior facility was amended during the second quarter of 2006 to
    permit, among other things, our cash tender offer for our
    4.0% convertible subordinated notes and the issuance of our
    3.75% convertible subordinated notes, each as described below.
    Upon the amendment and restatement of our credit facility, the
    obligations under the prior facility were terminated, and
    related unamortized debt issuance costs in the amount of
    approximately $2.6 million were expensed in the second
    quarter of 2006 and included in interest expense. As of
    December 31, 2005, we had approximately $142.6 million
    of letters of credit outstanding under the prior credit facility
    and $7.5 million outstanding as a term loan.
    4.0% Convertible
    Subordinated Notes
    As of September 30, 2006, we had $33.3 million
    aggregate principal amount of 4.0% convertible subordinated
    notes (4.0% Notes) outstanding, which was classified as a
    current obligation as these 4.0% Notes will mature within
    the next twelve months. The credit facility permits the
    repayment of these 4.0% Notes on or before maturity at
    Quantas sole discretion. The 4.0% Notes are
    convertible into shares of our common stock at a price of
    $54.53 per share, subject to adjustment as a result of
    certain events. The sale of the notes and the shares issuable
    upon conversion thereof was registered in a registration
    statement filed with the SEC. The 4.0% Notes require
    semi-annual interest payments on July 1 and
    December 31 until the notes mature on July 1, 2007. We
    have the option to redeem some or all of the 4.0% Notes at
    specified redemption prices, together with accrued and unpaid
    interest. If certain fundamental changes occur, as described in
    the indenture under which we issued the 4.0% Notes, holders of
    the 4.0% Notes may require us to purchase all or part of
    the notes at a purchase price equal to 100% of the principal
    amount, plus accrued and unpaid interest. During the second
    quarter of 2006, we conducted a cash tender offer for all of the
    4.0% Notes, which resulted in the repurchase of
    $139.2 million of the 4.0% Notes. As a result of the
    repurchase of a portion of the 4.0% Notes, we recorded a
    gain on early extinguishment of debt of approximately
    $2.1 million, during the second quarter of 2006, which was
    partially offset by costs associated with the tender offer of
    approximately $0.5 million. In addition, approximately
    $0.7 million in related unamortized debt issuance costs
    associated with the retirement of a portion of the repurchased
    4.0% Notes has been expensed and included in interest
    expense.
    4.5% Convertible
    Subordinated Notes
    As of September 30, 2006, we had $270.0 million
    aggregate principal amount of 4.5% convertible subordinated
    notes (4.5% Notes) outstanding. 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 Quantas 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 us 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
    
    24
Table of Contents
    combination thereof, with the amount of cash determined in
    accordance with the terms of the indenture under which the notes
    were issued. During the third quarter of 2006, the market price
    condition described in clause (i) above was satisfied, and
    the notes are presently convertible at the option of each
    holder. The conversion period will expire on December 31,
    2006, but may resume upon the satisfaction of the market
    condition or other conditions in future periods.
    Beginning October 8, 2008, we can 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
    October 1, 2008, 2013 or 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 repurchase 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. We presently do not anticipate using stock to
    satisfy any future repurchase obligations. If we were to satisfy
    the obligation with shares of our common stock, the number of
    shares delivered would 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 number of shares to be
    issued under this circumstance is not limited. 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.
    3.75% Convertible
    Subordinated Notes
    As of September 30, 2006, we had $143.8 million
    aggregate principal amount of 3.75% convertible
    subordinated notes due 2026 (3.75% Notes) outstanding. 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 which we filed with the SEC during the
    third quarter of 2006. 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, commencing on October 30, 2006.
    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 our 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. 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 pay contingent interest 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.
    
    25
Table of Contents
    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, 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 and surety guarantees. We
    have not engaged in any off-balance sheet financing arrangements
    through special purpose entities.
    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 the 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
    September 30, 2006, the maximum guaranteed residual value
    was approximately $102.9 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 claims will be made under a
    letter of credit in the foreseeable future.
    As of September 30, 2006, we had approximately
    $125.4 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 2006 and 2007. Upon maturity, it is expected that the
    majority of these letters of credit will be renewed for
    subsequent one-year periods. Subsequent to September 30,
    2006, we posted an additional letter of credit in the amount of
    $30.0 million in connection with certain performance
    guarantees for a project.
    Performance
    Bonds
    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 the
    surety, we have posted letters of credit in the amount of
    $15.0 million in favor of the surety and, with the consent
    of our lenders under our credit facility, we have
    
    26
Table of Contents
    granted security interests in certain of our assets to
    collateralize our obligations to the surety. We may be required
    to post additional letters of credit or other collateral in
    favor of the surety or our customers in the future. Posting
    letters of credit in favor of the surety or our customers also
    will reduce the borrowing availability under our credit
    facility. To date, we have not been required to make any
    reimbursements to the surety 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
    September 30, 2006, an aggregate of approximately
    $568.6 million in original face amount of bonds issued by
    the surety were outstanding. Our estimated cost to complete
    these bonded projects was approximately $143.2 million as
    of September 30, 2006.
    Contractual
    Obligations
    As of September 30, 2006, our future contractual

    Excluded from the above table is interest associated with
    borrowings under our credit facility because both the amount
    borrowed and applicable interest rate are variable. As of
    September 30, 2006, 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 for future periods
    in advance.
    Concentration
    of Credit Risk
    We grant credit under normal payment terms, generally without
    collateral, to our 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. No customer accounted for more than 10% of accounts
    receivable as of September 30, 2006 or revenues for the
    three or nine months ended September 30, 2006.
    Litigation
    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 contract
    and/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.

    Certain Hybrid Financial Instruments  An Amendment of
    FASB Statements No. 133 and 140.
    SFAS No. 155 provides entities with relief from having
    to separately determine the fair value of an embedded derivative
    that would otherwise be required to be bifurcated from its host
    contract in accordance with SFAS No. 133.
    SFAS No. 155 allows an entity to make an irrevocable
    election to measure such a hybrid financial instrument at fair
    value in its entirety, with changes in fair value recognized in
    earnings. SFAS No. 155 is effective for all financial
    instruments acquired, issued or subject to a remeasurement event
    occurring after the beginning of an entitys first fiscal
    year that begins after September 15, 2006. We do not have
    any financial instruments that fall under the scope of this
    statement and do not believe that the adoption of
    SFAS No. 155 will have a material impact on our
    financial position, results of operations or cash flows.
    In July 2006, the FASB issued Interpretation (FIN) No. 48,
    Accounting for Uncertainty in Income Taxes  An
    Interpretation of FASB Statement 109.
    FIN No. 48 prescribes a comprehensive model for
    recognizing, measuring, presenting and disclosing uncertain tax
    positions within financial statements. The provisions of
    FIN No. 48 are effective for fiscal years beginning
    after December 15, 2006. We are currently analyzing the
    provisions of FIN No. 48 and have not yet made a
    determination of the impact the adoption will have on our
    consolidated financial positions, results of operations and cash
    flows.
    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. Quanta is currently analyzing the provisions of
    SFAS No. 157 and determining how it will affect
    accounting policies and procedures and has not yet made a
    determination of the impact the adoption will have on its
    consolidated financial position, results of operations and cash
    flows.
    In September 2006, the SEC issued Staff Accounting
    Bulletin No. 108, Considering the Effects of
    Prior Year Misstatements when Quantifying Misstatements in
    Current Year Financial Statements (SAB 108), which
    provides guidance on the consideration of the effects of prior
    year misstatements in quantifying current year misstatements for
    the purpose of a materiality assessment. SAB 108 requires
    that the materiality of the effect of a misstated amount be
    evaluated on each financial statement and the related financial
    statement disclosures, and that materiality evaluation be based
    on quantitative and qualitative factors. SAB 108 is
    effective for fiscal years beginning after November 15,
    2006. Quanta does not believe this guidance will have a material
    impact on Quantas financial position, results of
    operations or cash flows.
    Critical
    Accounting Policies
    The discussion and analysis of our financial condition and
    results of operations are based on our consolidated financial
    statements, which have been prepared in accordance with
    accounting principles generally accepted in the United States.
    The preparation of these consolidated financial statements
    requires us to make estimates and assumptions that affect the
    reported amounts of assets and liabilities, disclosures of
    contingent assets and liabilities known to exist at the date of
    the consolidated financial statements and the reported amounts
    of revenues and expenses during the reporting period. We
    evaluate our estimates on an ongoing basis, based on historical
    experience and on various other assumptions that are believed to
    be reasonable under the circumstances. There can be no assurance
    that actual results will not differ from those estimates.
    Management has reviewed its development and selection of
    critical accounting estimates with the audit committee of our
    board of directors. We believe the following accounting policies
    affect our more significant judgments and estimates used in the
    preparation of our consolidated financial statements:
    Revenue Recognition.  We recognize revenue when
    services are performed except when work is being performed under
    a fixed price contract. 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. Such contracts
    generally provide that the customer accept completion of
    progress to date and compensate us for services rendered,
    measured typically in terms of units installed, hours expended
    or
    
    28
Table of Contents
    some other measure of progress. Contract costs typically 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.
    Provisions for the total estimated losses on uncompleted
    contracts are made in the period in which such losses are
    determined. Changes in job performance, job conditions,
    estimated profitability and final contract settlements may
    result in revisions to costs and income and their effects are
    recognized in the period in which the revisions are determined.
    Self-Insurance.  We are insured for
    employers liability and general liability claims, subject
    to a deductible of $1.0 million per occurrence, and for
    auto liability and workers compensation subject to a
    deductible of $2.0 million per occurrence. In addition,
    beginning August 1, 2006, we are subject to an additional
    cumulative aggregate liability of up to $2.0 million on
    workers compensation claims in excess of $2.0 million
    per occurrence per policy year. We also have an employee health
    care benefit plan for employees not subject to collective
    bargaining agreements, which is subject to a deductible of
    $250,000 per claimant per year. Losses are accrued based
    upon our estimates of the ultimate liability for claims incurred
    and an estimate of claims incurred but not reported, with
    assistance from a third-party actuary. However, insurance
    liabilities are difficult to assess and estimate due to unknown
    factors, including the severity of an injury, the determination
    of our 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.
    Our 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 insurers financial
    situation further deteriorates, we may be required to pay
    certain obligations that otherwise would have been paid by this
    insurer. We estimate that the total future claim amount that
    this insurer is currently obligated to pay on our behalf for the
    above mentioned policy periods is approximately
    $4.5 million; however, our estimate of the potential range
    of these future claim amounts is between $3.0 million and
    $9.5 million. The actual amounts ultimately paid by us 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. In any event, we do not expect any failure by
    this insurer to honor its obligations to us to have a material
    adverse impact on our financial condition; however, the impact
    could be material to our results of operations or cash flow in a
    given period. We continue to monitor the financial situation of
    this insurer and analyze any alternative actions that could be
    pursued.
    Valuation of Intangibles and Long-Lived
    Assets.  SFAS No. 142 provides that
    goodwill and other intangible assets that have indefinite useful
    lives not be amortized but, instead, must be tested at least
    annually for impairment, and intangible assets that have finite
    useful lives should continue to be amortized over their useful
    lives. SFAS No. 142 also provides specific guidance
    for testing goodwill and other nonamortized intangible assets
    for impairment. SFAS No. 142 does not allow increases
    in the carrying value of reporting units that may result from
    our impairment test; therefore, we may record goodwill
    impairments in the future, even when the aggregate fair value of
    our reporting units and the company as a whole may increase.
    Goodwill of a reporting unit will be tested for impairment
    between annual tests if an event occurs or circumstances change
    that would more likely than not reduce the fair value of a
    reporting unit below its carrying amount. Examples of such
    events or circumstances may include a significant change in
    business climate or a loss of key personnel, among others.
    SFAS No. 142 requires that management make certain
    estimates and assumptions in order to allocate goodwill to
    reporting units and to determine the fair value of reporting
    unit net assets and liabilities, including, among other things,
    an assessment of market conditions, projected cash flows, cost
    of capital and growth rates, which could significantly impact
    the reported value of goodwill and other intangible assets.
    Estimating future cash flows requires significant judgment, and
    our projections may vary from cash flows eventually realized.
    We review long-lived assets for impairment whenever events or
    changes in circumstances indicate that the carrying amount may
    not be realizable. If an evaluation is required, the estimated
    future undiscounted cash flows associated with the asset are
    compared to the assets carrying amount to determine if an
    impairment of such asset is necessary. Estimating future cash
    flows requires significant judgment, and our projections may
    vary from cash flows eventually realized. The effect of any
    impairment would be to expense the difference
    
    29
Table of Contents
    between the fair value of such asset and its carrying value. In
    addition, we estimate the useful lives of our long-lived assets
    and other intangibles. We periodically review factors to
    determine whether these lives are appropriate. Net gains or
    losses from the sale of property and equipment are reflected in
    Selling, General and Administrative Expenses.
    Current and Non-Current Accounts and Notes Receivable
    and Provision for Doubtful Accounts.  We provide
    an allowance for doubtful accounts when collection of an account
    or note receivable is considered doubtful. Inherent in the
    assessment of the allowance for doubtful accounts are certain
    judgments and estimates relating to, among others, our
    customers access to capital, our customers
    willingness or ability to pay, general economic conditions and
    the ongoing relationship with the customer. Should customers
    experience financial difficulties or file for bankruptcy, or
    should anticipated recoveries relating to the receivables in
    existing bankruptcies and other workout situations fail to
    materialize, we could experience reduced cash flows and losses
    in excess of current reserves. In addition, material changes in
    our customers revenues or cash flows could affect our
    ability to collect amounts due from them.
    Income Taxes.  We follow the liability method
    of accounting for income taxes in accordance with
    SFAS No. 109, Accounting for Income Taxes.
    Under this method, deferred 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.
    We regularly evaluate valuation allowances established for
    deferred tax assets for which future realization is uncertain
    and we maintain an allowance for tax contingencies that we
    believe is adequate. 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. We consider
    projected future taxable income and tax planning strategies in
    making this assessment. If actual future taxable income differs
    from our estimates, we may not realize deferred tax assets to
    the extent we have estimated.
    Outlook
    The following statements are based on current expectations.
    These statements are forward-looking, and actual results may
    differ materially.
    Many utilities across the country have regained their financial
    health and we believe they are making plans to increase spending
    on their transmission and distribution systems. As a result, we
    anticipate more new construction, extensive pole change outs,
    line upgrades and maintenance projects on many systems over the
    next several quarters. Further, the recently enacted Energy
    Policy Act of 2005 requires the power industry to meet federal
    reliability standards for their transmission and distribution
    systems and provides further incentives to the industry to
    invest in and improve maintenance on their systems. While this
    Act is likely to stimulate spending by our customers, we do not
    expect to begin to realize substantial benefits of this spending
    for at least twelve to eighteen months.
    We are also seeing improvement in the financial health of
    telecommunications customers. There are several
    telecommunications initiatives currently in discussion and
    underway by several wireline carriers and government
    organizations that provide us with pockets of opportunity,
    particularly from fiber to the premises (FTTP) and fiber to the
    node (FTTN) initiatives. Such initiatives are underway by
    Verizon and have been announced by AT&T, and municipalities
    and other government jurisdictions have also become active in
    these initiatives. We anticipate 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 third generation technology.
    Spending in the cable television industry remains flat. However,
    with several telecommunications companies increasing the pace of
    their FTTP and FTTN projects that will enable them to offer TV
    services via fiber to their customers, such initiatives could
    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. On July 21, 2006,
    Adelphia Communications Corporation and its affiliated companies
    (Adelphia) signed a plan agreement with their creditors
    committee and
    
    30
Table of Contents
    other unsecured creditors providing a framework for a plan of
    reorganization intended to result in Adelphias emergence
    from Chapter 11 bankruptcy in the fourth quarter of 2006.
    The plan of reorganization outlined in the plan agreement was
    conditioned on Adelphias closing of the sale of
    substantially all of its assets to Time Warner Cable and Comcast
    Corporation and, on July 31, 2006, the sale was
    successfully completed. As a result of these transactions, we
    have begun to see spending by Time Warner Cable and Comcast
    Corporation as they integrate the systems acquired from Adelphia.
    We continue to evaluate 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 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 stabilization of several of our markets and our margin
    enhancement initiatives, we have begun 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 integration of any future acquisitions,
    could result in future charges related to, among others,
    severance, facilities shutdown and consolidation, property
    disposal and other exit costs.
    Capital expenditures in 2006 are expected to be approximately
    $60.0 million. A majority of the expenditures will be for
    operating equipment. We expect expenditures for 2006 to be
    funded substantially through internal cash flows and, to the
    extent necessary, from cash on hand.
    We believe that we are adequately positioned to capitalize upon
    opportunities in the industries we serve because of our proven
    full-service operating units with broad geographic reach,
    financial capability and technical expertise.

    otherwise included in this report. In addition, we do not
    undertake any obligation to update any forward-looking
    statements to reflect events or circumstances after the date of
    this report.
| 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 interest rates in Part II, Item 7A, Quantitative
    and Qualitative Disclosures About Market Risk, in our Annual
    Report on
    Form 10-K
    for the year ended December 31, 2005. Our primary exposure
    to market risk relates to unfavorable changes in interest rates
    and changes in equity investment prices.
    Since December 31, 2005, we have issued the
    3.75% Notes and repurchased a portion of our
    4.0% Notes. As of December 31, 2005, the fair value of
    our fixed-rate debt of $444.8 million aggregate principal
    amount was approximately $520.1 million, based upon current
    market prices and as of September 30, 2006, the fair value
    of our fixed-rate debt of $449.0 million aggregate
    principal amount was approximately $626.7 million, based
    upon current market prices.
| Item 4. | Controls and Procedures. | 
    Attached as exhibits to this quarterly report on
    Form 10-Q
    are certifications of Quantas Chief Executive Officer and
    Chief Financial Officer that are required in accordance with
    Rule 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
    Securities and Exchange Commissions (the SEC)
    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 to
    Rule 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 September 30, 2006, our disclosure controls and
    procedures were effective to provide reasonable assurance of
    achieving their objectives.
    Inherent
    Limitations on Effectiveness of Controls
    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
    systems 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
    
    33
Table of Contents
    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.
    Internal
    Control over Financial Reporting
    There has been no change in our internal control over financial
    reporting that occurred during the quarter ended
    September 30, 2006, that has materially affected, or is
    reasonably likely to materially affect, our internal control
    over financial reporting.
    PART II 
    OTHER INFORMATION
    QUANTA SERVICES, INC. AND SUBSIDIARIES
| Item 1. | Legal Proceedings. | 
    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 contract
    and/or
    property damage, punitive damages, civil penalties or other
    losses, or injunctive or declaratory relief. With respect to all
    such lawsuits, claims and proceedings, we accrue reserves when
    it is probable 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 results of
    operations, cash flow or financial position.
| 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 on
    Form 10-K
    for the year ended December 31, 2005 (2005 Annual Report)
    except as noted below. 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 2005 Annual Report as well as the below risk
    factor. 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.
    The Energy Policy Act of 2005 may fail to result in increased
    spending in the electric power transmission
    infrastructure.  Implementation of the Energy
    Policy Act of 2005 is still subject to considerable fiscal and
    regulatory uncertainty. Many of the regulations implementing the
    components of the Act have not been promulgated and many others
    have only recently been finalized, and the effect of these
    regulations, once implemented, is uncertain. As a result, the
    legislation may not result in increased spending on the electric
