MASTEC, INC. CONSOLIDATED STATEMENTS OF CASH FLOWS (Continued) (Unaudited) Supplemental disclosure of non-cash investing and financing activities: During the nine months ended September 30, 2001, we completed certain acquisitions which have been accounted for as purchases. The fair value of the net assets excluding goodwill acquired totaled $2.7 million and was comprised primarily of $3.0 million of accounts receivable, $2.0 million of property and equipment, $0.5 million of other assets and $0.2 million in cash, offset by $3.0 million of assumed liabilities. The excess of the purchase price over the fair value of net assets acquired was $2.7 million and was allocated to goodwill. The total purchase price of $5.4 million is comprised of $4.5 million in cash and the balance in seller financing. We also paid approximately $22.3 million related to contingent consideration from earlier acquisitions of which $0.6 million was reflected as additional goodwill and $21.7 million reflected as a reduction in other current liabilities. During the nine months ended September 30, 2000, we completed certain acquisitions which have been accounted for as purchases. The fair value of the net assets excluding goodwill acquired totaled $18.0 million and was comprised primarily of $26.9 million of accounts receivable, $8.9 million of property and equipment, $1.0 million of other assets and $5.8 million in cash, offset by $24.6 million of assumed liabilities. The excess of the purchase price over the fair value of net assets acquired was $67.3 million and was allocated to goodwill. The total purchase price of $85.3 million was comprised of $48.7 million in cash, $24.0 million in stock and $12.6 million in seller financing. We also issued 207,171 shares of common stock with a value of $15.8 million and paid approximately $7.6 million in cash related to contingent consideration for earlier acquisitions of which $21.5 million was reflected as additional goodwill and $1.9 million reflected as a reduction in other current liabilities. The accompanying notes are an integral part of these consolidated financial statements.

MASTEC, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1 - Basis for Presentation of Consolidated Financial Statements The accompanying unaudited consolidated financial statements of MasTec, Inc. have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions for Form 10-Q and Rule 10-01 of Regulation S-X. They do not include all information and notes required by generally accepted accounting principles for complete financial statements and should be read together with the audited financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 2000. The balance sheet data as of December 31, 2000 was derived from audited financial statements but does not include all disclosures required by generally accepted accounting principles. Certain reclassifications have been made to conform to the 2001 presentation. The financial information furnished reflects all adjustments, consisting only of normal recurring accruals, which are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations and cash flows for the quarterly periods presented. The results of operations for the periods presented are not necessarily indicative of our future results of operations for the entire year. Our comprehensive (loss) income for the nine months ended September 30, 2001 and 2000 was $(78.4) million and $57.3 million, respectively. The components of comprehensive (loss) income are net (loss) income and foreign currency translation adjustments. In July 2001, the Financial Accounting Standards Board (the "FASB") issued SFAS No. 141, Business Combinations. SFAS No. 141 requires that all business combinations initiated after June 30, 2001, be accounted for using the purchase method. The FASB also issued SFAS No. 142, Goodwill and Other Intangible Assets. SFAS No. 142 requires that goodwill be assessed at least annually for impairment by applying a fair-value based test. Goodwill will no longer be amortized over its estimated useful life. In addition, acquired intangible assets are required to be recognized and amortized over their useful lives if the benefit of the asset is based on contractual or legal rights. While we will be subject to most provisions of SFAS No. 142 beginning January 1, 2002, goodwill and intangible assets acquired after June 30, 2001, will be subject immediately to the statement. We are currently evaluating what additional impact these new accounting standards may have on the Company's financial position or results of operations. However, with the recent decline in the Company's market capitalization, the adoption of SFAS No. 142 may result in the write-off or write-down of the Company's goodwill. In October 2001, the FASB issued FAS 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("FAS 144"). FAS 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets. This statement supersedes FAS 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" ("FAS 121") and establishes a single accounting model, based on the framework established in FAS 121, for long-lived assets to be disposed of by sale. We are required to adopt FAS 144 no later than January 1, 2002. We are currently evaluating the potential impact, if any, the adoption of FAS 144 will have on our financial position and results of operations.

MASTEC, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 2 - Debt Debt is comprised of the following (in thousands): September 30, December 31, 2001 2000 ------------ ----------- Revolving credit facility at LIBOR plus 1.0% (3.59% at September 30, 2001 and 7.64% at December 31, 2000) $ 75,000 $ 7,000 Other bank facilities at LIBOR plus 1.5% (4.13% at September 30, 2001 and 8.06% at December 31, 2000) 2,047 517 Notes payable for equipment, at interest rates from 7.5% to 8.5% due in installments through the year 2004 3,504 6,161 7.75% senior subordinated notes due February 2008 195,825 195,805 -------- -------- Total debt 276,376 209,483 Less current maturities (77,258) (3,323) -------- -------- Long-term debt $199,118 $206,160 ======== ======== We have a credit facility that provides for borrowings up to an aggregate of $100.0 million. Amounts outstanding under the revolving credit facility mature on June 9, 2002. We have amended the facility to modify certain terms and conditions including interest rates and certain financial ratio coverages, which we currently meet. The credit facility, as amended, is secured by a pledge of substantially all of our assets. Interest under the facility accrues at rates based, at our option, on the agent bank's base rate plus a margin of up to 0.50% depending on certain financial covenants or 1.0% above the overnight federal funds effective rate, whichever is higher, or its LIBOR Rate (as defined in the credit facility) plus a margin of 2.25%. We have received three proposals from current and prospective lenders for a new long-term credit facility, which we are currently evaluating. There can be no assurance that we will be able to secure a new facility on comparable terms or at all prior to the expiration of the current credit facility. The credit facility contains customary events of default and covenants which prohibit, among other things, making investments in excess of a specified amount, incurring additional indebtedness in excess of a specified amount, incurring a net loss in consecutive quarters, paying dividends in excess of a specified amount, making capital expenditures in excess of a specified amount, creating liens, prepaying other indebtedness, including our 7.75% senior subordinated notes, exceeding certain levels of days' sales outstanding, and engaging in certain mergers or combinations without the prior written consent of the lenders. The credit facility also provides that we must maintain financial ratio coverages at the end of each fiscal quarter such as debt to earnings and earnings to interest expense. Failure to achieve certain results could cause us not to meet these covenants. There can be no assurance that we will continue to meet these covenant tests in future periods. Although we do not believe that these circumstances will occur, if we violate one or more covenants in future periods, and we are unable to cure or obtain waivers from our lenders or amend or otherwise restructure our credit facility, we could be in default under the facility and our senior subordinated notes, and we may be required to sell assets for other than their carrying value to repay this indebtedness. Note 3 - Operations by Segments and Geographic Areas The following table sets forth, for the three months and nine months ended September 30, 2001 and 2000, certain information about segment results of operations and segment assets (in thousands):

As of September 30, 2001 and 2000, total assets for Brazil consisted of $35.8 million and $49.4 million, respectively, and the remainder relates to non-core international assets. Included for the three months and nine months ended September 30, 2001, a $10.0 million write-down of non-core international assets, a reserve charge of $1.0 million and a severance expense of $0.8 million. For the nine months ended September 30, 2000, includes a $4.5 million net gain on sale of a non-core international asset. (2) Consists of non-core and corporate operations, which includes interest expense, net of interest income. For the three months ended September 30, 2001 and 2000, interest expense, net of interest income, was $5.0 million and $3.1 million, respectively, and $9.8 million and $11.3 million for the nine months ended September 30, 2001 and 2000, respectively. The three and nine month results for the period ended September 30, 2001, includes a write-down of assets and severance costs totaling $63.3 million and $71.5 million, respectively. (3) Includes for the three months and nine months ended September 30, 2001, a reserve of $51.4 million and $89.4 million, respectively.

MASTEC, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS There are no significant transfers between geographic areas and segments. Total assets are those assets used in our operations in each segment. Corporate assets include domestic cash and cash equivalents, non-core assets held for sale and notes receivable. Note 4 - Commitments and Contingencies We have lawsuits pending in Florida federal court against Sintel International Corp., a subsidiary of Artcom Technologies, Inc., to recover more than $5.0 million due under a promissory note and for breach of contract. We are also pursuing other claims against Artcom affiliates totaling approximately $4.0 million. Artcom has responded by suing us in federal court in Florida to recover approximately $6.0 million (subject to trebling) it alleges we received as a result of certain allegedly unauthorized transactions by two former employees of Artcom. In a related matter, the labor union representing the workers of Sistemas e Instalaciones de Telecomunicacion S.A. ("Sintel"), a sister company of Sintel International, has instigated an investigative action with a Spanish federal court alleging that five former members of the board of directors of Sintel, including Jorge Mas, the Chairman of the Board of MasTec, and his brother Juan Carlos Mas, a MasTec executive, approved a series of allegedly unlawful transactions that led to the bankruptcy of Sintel. We are also named as a potentially liable party. The union alleges Sintel and its creditors were damaged in the approximate amount of 13 billion pesetas ($71.1 million at September 30, 2001 exchange rates). Neither we nor our executives have yet been served in the action. In November 1997, we filed a suit against Miami-Dade County in Florida state court alleging breach of contract and seeking damages exceeding $3.0 million in connection with the county's refusal to pay amounts due to us under a multi-year agreement to perform road restoration work for the Miami-Dade Water and Sewer Department ("MWSD"), a department of the county. The county has counterclaimed against us seeking unspecified damages. We are vigorously litigating the actions described above. We are also a party to other pending legal proceedings arising in the normal course of business, none of which we believe is material to our financial position or results of operations. Our operations in Brazil are subject to the risks of political, economic or social instability, including the possibility of expropriation, confiscatory taxation, hyper-inflation or other adverse regulatory or legislative developments, or limitations on the repatriation of investment income, capital and other assets. We cannot predict whether any of such factors will occur in the future or the extent to which such factors would have a material adverse effect on our Brazilian operations. Note 5 - Client Credit Risk Certain of our clients, primarily competitive telecommunications carriers, have filed for bankruptcy or have been experiencing financial difficulties. We review all our clients on a regular basis, and as a result increased our reserves by $106.7 million and $144.7 million during the three months and nine months ended September 30, 2001, respectively, to reflect that certain clients may be unable to meet their obligations to us in the future. Should additional clients file for bankruptcy or experience difficulties, or should anticipated recoveries in existing bankruptcy and other workout situations fail to materialize, we could experience reduced cash flows and losses in excess of current reserves.

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION Except for historical information, the matters discussed below may contain forward-looking statements, such as statements regarding MasTec's future plans and anticipated trends in the industries and economies in which MasTec operates. These forward-looking statements are based on MasTec's current expectations and are subject to a number of risks, uncertainties, and assumptions, including that our revenue may differ from that projected, that we may be further impacted by slowdowns in our clients' businesses or deterioration in our clients' financial condition, that our reserves may be inadequate or our equity investments may be impaired, that we may experience increased costs associated with realigning our business or may be unsuccessful in those efforts and that we may not continue to be in compliance with our credit facility covenants. Should one or more of these risks or uncertainties materialize, or should the underlying assumptions prove incorrect, actual results may differ significantly from results expressed or implied in any forward-looking statements made by MasTec. These and other risks are detailed in this quarterly report and in other documents filed by MasTec with the Securities and Exchange Commission, including our registration statement on Form S-3 (No. 333-90027). MasTec does not undertake any obligation to revise these forward-looking statements to reflect future events or circumstances. General We are a leading end-to-end voice, video, data and energy network infrastructure solution for a broad range of communications, broadband, government, energy and other corporate clients. We have a diverse client base representing all the major segments of the industries we serve. We design, build, install, maintain and monitor internal and external networks and transmission facilities for communication, transportation, computing and energy systems.

Three Months Ended September 30, 2001 Compared to Three Months Ended September 30, 2000 The following table sets forth the revenue and change in revenue by operating segments, in dollar and percentage terms (in thousands): Three Months Ended September 30, Change ------------------ ----------------- 2001 2000 $ % -------- -------- --------- ------ Datacom network services $247,486 $331,578 $(84,092) (25.4)% Energy network services 39,097 33,882 5,215 15.4 International 15,660 16,819 (1,159) (6.9) -------- -------- --------- ------ $302,243 $382,279 $(80,036) (20.9)% ======== ======== ========= Our revenue was $302.2 million for the three months ended September 30, 2001, compared to $382.3 million for the same period in 2000, representing a decrease of $80.0 million or 20.9% primarily due to a reduction in capital expenditures by incumbent telecom clients and our decision to reduce services to competitive telecommunications carriers. Our costs of revenue were $247.4 million or 81.9% of revenue for the three months ended September 30, 2001, compared to $293.4 million or 76.7% of revenue for the same period in 2000. In 2001, margins were impacted by the following: under-utilization of personnel and equipment related to certain energy client contracts; start-up costs for new projects; losses related to two short-term network services projects performed primarily during the quarter; and demobilization and redeployment costs as we adjusted to reduced capital spending by telecommunication carriers. Depreciation was $12.3 million or 4.1% of revenue for the three months ended September 30, 2001, compared to $13.5 million or 3.5% of revenue for the same period in 2000. Depreciation expense in 2001 was lower due to reduced capital expenditures throughout the year. Amortization was $2.4 million or 0.8% of revenue for the three months ended September 30, 2001, compared to $2.5 million or 0.6% of revenue for the same period in 2000. Amortization of goodwill net of tax was $1.4 million in 2001 and $1.8 million in 2000. General and administrative expenses were $142.4 million or 47.1% of revenue for the three months ended September 30, 2001, compared to $27.5 million or 7.2% of revenue for the same period in 2000. Included in general and administrative expense in 2001 is a reserve for bad debt of $106.7 million to provide for receivables from clients who have filed for bankruptcy or are experiencing financial difficulties and a charge of $9.8 million primarily related to severance payments to our former president and chief executive officer. Excluding these charges and reserves, general and administrative expenses were $25.9 million or 8.6% of revenue, a reduction of $1.6 million from the prior year. Interest expense, net of interest income, was $5.0 million or 1.7% of revenue for the three months ended September 30, 2001, compared to $2.9 million or 0.8% of revenue for the same period in 2000. The increase in net interest expense of $2.1 million was due primarily to increased borrowing to meet working capital needs. Other (loss) income was $(10.2) million or (3.3)% of revenue for the three months ended September 30, 2001, compared to $(0.01) million or (0.1)% of revenue for the same period in 2000. Other loss for 2001 primarily consists of a $10.0 million write-down of non-core international assets. For the three months ended September 30, 2001, our effective tax rate was approximately 36.0% for North American operations and 33.0% for Brazilian operations, compared to 41.0% and 33.0% in 2000 for North American and Brazilian operations, respectively.

Nine Months Ended September 30, 2001 Compared to Nine Months Ended September 30, 2000 The following table sets forth the revenue and change in revenue by operating segments, in dollar and percentage terms (in thousands): Nine Months Ended September 30, Change ------------------ --------------- 2001 2000 $ % -------- -------- -------- ----- Datacom network services $811,805 $806,114 $ 5,691 0.7% Energy network services 114,841 108,136 6,705 6.2 International 43,029 38,420 4,609 12.0 -------- -------- -------- ----- $969,675 $952,670 $ 17,005 1.8% Our revenue was $969.7 million for the nine months ended September 30, 2001, compared to $952.7 million for the same period in 2000, representing an increase of $17.0 million or 1.8%. While we experienced marginal growth during the first nine months of 2001, the growth rate was lower than originally anticipated and revenue for the remainder of 2001 is expected to decrease from the year earlier period due to a reduction in capital expenditures by telecommunications clients. Our costs of revenue were $785.5 million or 81.0% of revenue for the nine months ended September 30, 2001, compared to $727.2 million or 76.3% of revenue for the same period in 2000. In 2001, margins were impacted by the following: under-utilization of personnel and equipment related to certain energy client contracts; start-up costs for new projects; losses related to two short-term network services projects performed primarily during the third quarter; and demobilization and redeployment costs as we adjusted to reduced capital spending by telecommunication carriers. Depreciation was $39.1 million or 4.0% of revenue for the nine months ended September 30, 2001, compared to $40.2 million or 4.2% of revenue for the same period in 2000. The slight reduction in depreciation expense in 2001 was due to reduced capital expenditures. Amortization was $8.0 million or 0.8% of revenue for the nine months ended September 30, 2001, compared to $8.6 million or 1.0% of revenue for the same period in 2000. Amortization of goodwill net of tax was $4.8 million in 2001 and $6.3 million in 2000. General and administrative expenses were $226.5 million or 23.4% of revenue for the nine months ended September 30, 2001, compared to $72.6 million or 7.6% of revenue for the same period in 2000. Included in general and administrative expense in 2001 is a reserve for bad debt of $144.7 million to provide for receivables from clients who have filed for bankruptcy or are experiencing financial difficulties and a charge of $11.5 million primarily related to severance for our former president and chief executive officer. Excluding these charges and reserves, general and administrative expenses were $70.3 million or 7.2% of revenue, a reduction of $2.3 million from the prior year. Interest expense, net of interest income, was $9.7 million or 1.0% of revenue for the nine months ended September 30, 2001, compared to $10.5 million or 1.1% of revenue for the same period in 2000. The decrease in net interest expense of $0.8 million was due primarily to reduced interest income recognized from a client with extended payment terms. Other (loss) income was $(15.8) million or (1.7)% of revenue for the nine months ended September 30, 2001, compared to $5.2 million or 0.6% of revenue for the same period in 2000. In 2001, the loss was primarily due to an impairment charge of $6.5 million related to our equity investment in a client and a $10.0 million write-down of non-core international assets. In 2000, we recognized a net gain of $4.5 million related to the disposal of non-core international assets. For the nine months ended September 30, 2001, our effective tax rate was approximately 36.0% for North American operations and 33.0% for Brazilian operations, compared to 41.0% and 33.0% in 2000 for North American and Brazilian operations, respectively. Financial Condition, Liquidity and Capital Resources Our primary liquidity needs are for working capital, capital expenditures, acquisitions and investments, and debt service. Our primary sources of liquidity are cash flows from operations and borrowings under revolving lines of credit. We currently have available approximately $42.0 million in cash and credit under our credit facility. We also anticipate receiving approximately $41.4 million in income tax refunds in the first half of 2002 as a result of net losses reflected through September 30, 2001. Net cash provided by operating activities was $2.3 million for the nine months ended September 30, 2001, compared to $6.8 million for the same period in 2000. Net cash provided by operating activities in 2001 and 2000 was due principally to changes in working capital. We have a credit facility that provides for borrowings up to an aggregate of $100.0 million. Amounts outstanding under the revolving credit facility mature on June 9, 2002. We have amended the facility to modify certain terms and conditions including interest rates and certain financial ratio coverages, which we currently meet. The credit facility, as amended, is secured by a pledge of substantially all of our assets. Interest under the facility accrues at rates based, at our option, on the agent bank's base rate plus a margin of up to 0.50% depending on certain financial covenants or 1.0% above the overnight federal funds effective rate, whichever is higher, or its LIBOR Rate (as defined in the credit facility) plus a margin of 2.25%. We have received three proposals from current and prospective lenders for a new long-term credit facility, which we are currently evaluating. There can be no assurance that we will be able to secure a new facility on comparable terms or at all prior to the expiration of the current credit facility. The credit facility contains customary events of default and covenants which prohibit, among other things, making investments in excess of a specified amount, incurring additional indebtedness in excess of a specified amount, incurring a net loss in consecutive quarters, paying dividends in excess of a specified amount, making capital expenditures in excess of a specified amount, creating liens, prepaying other indebtedness, including our 7.75% senior subordinated notes, exceeding certain levels of days' sales outstanding, and engaging in certain mergers or combinations without the prior written consent of the lenders. The credit facility also provides that we must maintain financial ratio coverages at the end of each fiscal quarter such as debt to earnings and earnings to interest expense. Failure to achieve certain results could cause us not to meet these covenants. There can be no assurance that we will continue to meet these covenant tests in future periods. Although we do not believe that these circumstances will occur, if we violate one or more covenants in future periods, and we are unable to cure or obtain waivers from our lenders or amend or otherwise restructure our credit facility, we could be in default under the facility and our senior subordinated notes, and we may be required to sell assets for other than their carrying value to repay this indebtedness. Certain of our clients, primarily competitive telecommunications carriers, have filed for bankruptcy or have been experiencing financial difficulties. We review all our clients on a regular basis, and as a result increased our reserves by $106.7 million and $144.7 million during the three months and nine months ended September 30, 2001, respectively, to reflect the fact that certain clients may be unable to meet their obligations to us in the future. Should additional clients file for bankruptcy or experience difficulties, or should anticipated recoveries in existing bankruptcy and other workout situations fail to materialize, we could experience reduced cash flows and losses in excess of current reserves. We also have $200.0 million, 7.75% senior subordinated notes due in February 2008, with interest due semi-annually. During the nine months of 2001, we invested $26.0 million primarily in our fleet to replace or upgrade equipment, $6.5 in technology and $26.7 million in acquisitions, investments and consolidated subsidiaries. We have reflected in other current liabilities additional consideration related to earnouts for acquisitions completed in prior years of approximately $14.4 million, approximately $7.6 million related to our former chief executive officer's severance and $5.2 million payable for the remaining portion of the minority interest purchased all that we expect will be paid primarily during 2002. Impact of Inflation The primary inflationary factor affecting our operations is increased labor costs. We have not experienced significant increases in labor costs to date. Our Brazilian operations may, at times in the future, be exposed to risk associated with high inflation or currency devaluations. Recently Issued Accounting Pronouncements In July 2001, the Financial Accounting Standards Board (the "FASB") issued SFAS No. 141, Business Combinations. SFAS No. 141 requires that all businesscombinations initiated after June 30, 2001, be accounted for using the purchase method. The FASB also issued SFAS No. 142, Goodwill and Other Intangible Assets. SFAS No. 142 requires that goodwill be assessed at least annually for impairment by applying a fair-value based test. Goodwill will no longer be amortized over its estimated useful life. In addition, acquired intangible assets are required to be recognized and amortized over their useful lives if the benefit of the asset is based on contractual or legal rights. While we will be subject to most provisions of SFAS No. 142 beginning January 1, 2002, goodwill and intangible assets acquired after June 30, 2001, will be subject immediately to the statement. We are currently evaluating what additional impact these new accounting standards may have on the Company's financial position or results of operations. However, with the recent decline in the Company's market capitalization, the adoption of SFAS No. 142 may result in the write-off or write-down of the Company's goodwill. In October 2001, the FASB issued FAS 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("FAS 144"). FAS 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets. This statement supersedes FAS 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" ("FAS 121") and establishes a single accounting model, based on the framework established in FAS 121, for long-lived assets to be disposed of by sale. We are required to adopt FAS 144 no later than January 1, 2002. We are currently evaluating the potential impact, if any, the adoption of FAS 144 will have on our financial position and results of operations. ITEM 3.
