MasTec reports its results under 5 reportable segments: (1) Communications; (2) Oil and Gas; (3) Electrical Transmission; (4) Clean Energy and Infrastructure; and (5) Other. During the second quarter of 2020, the Company renamed its Power Generation and ~~Industrial;~~Industrial segment as the Clean Energy and ~~(5) Other.~~Infrastructure segment to better represent the nature of the segment’s operations, end markets and customer characteristics. There was no change to the composition of the segment or its historical results.

Basis of Presentation

The accompanying consolidated financial statements are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions for Form 10-Q and Rule 10-01 of Regulation S-X. Pursuant to these rules and regulations, certain information and footnote disclosures normally included in the annual audited consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. The accompanying consolidated balance sheet as of December 31, 2019 is derived from the Company’s audited financial statements as of that date. Because certain information and footnote disclosures have been condensed or omitted, these consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2019 contained in the Company’s 2019 Annual Report on Form 10-K (the “2019 Form 10-K”). In management’s opinion, all normal and recurring adjustments considered necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented have been included. When necessary, certain prior year amounts have been reclassified to conform to the current period presentation. Interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. The Company believes that the disclosures made in these consolidated financial statements are adequate to make the information not misleading.

Principles of Consolidation

The accompanying consolidated financial statements include MasTec, Inc. and its subsidiaries and include the accounts of all majority owned subsidiaries over which the Company exercises control and, when applicable, entities in which the Company has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. Other parties’ interests in entities that MasTec consolidates are reported as non-controlling interests within equity, except for mandatorily redeemable non-controlling interests, which are recorded within liabilities. Net income or loss attributable to non-controlling interests is reported as a separate line item below net income or loss. The Company’s investments in entities for which the Company does not have a controlling interest, but over which it has the ability to exert significant influence, are accounted for using the equity method of accounting. For equity investees in which the Company has an undivided interest in the assets, liabilities and profits or losses of an unincorporated entity, but does not exercise control over the entity, the Company consolidates its proportional interest in the accounts of the entity.

Translation of Foreign Currencies

The assets and liabilities of foreign subsidiaries with a functional currency other than the U.S. dollar are translated into U.S. dollars at period-end exchange rates, with resulting translation gains or losses included within other comprehensive income or loss. Revenue and expenses are translated into U.S. dollars at average rates of exchange during the applicable period. Substantially all of the Company’s foreign operations use their local currency as their functional currency. Currency gains or losses resulting from transactions executed in currencies other than the functional currency are included in other income or expense, net. In these consolidated financial statements, “$” means U.S. dollars unless otherwise noted.

Management Estimates

The preparation of consolidated financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates are based on historical experience and various other assumptions, including the ~~results~~potential future effects of ~~which~~the COVID-19 pandemic and other relevant global events. These estimates form the basis offor making judgments about the Company’s operating results and the carrying values of assets and liabilities that are not readily apparent from other sources. While management believes that such estimates are reasonable when considered in conjunction with the Company’s consolidated financial position and results of operations taken as a whole, actual results could differ materially from those estimates.

Key estimates include: the recognition of revenue and project profit or loss, which the Company defines as project revenue, less project costs of revenue, including project-related depreciation, in particular, on construction contracts accounted for under the cost-to-cost method, for which the recorded amounts require estimates of costs to complete and the amount and probability of variable consideration included in the contract transaction price; fair value estimates, including those related to acquisitions, valuations of goodwill and intangible assets, acquisition-related contingent consideration and other liabilities, equity ~~investments;~~investments and other long-lived assets; allowances for credit losses; asset lives used in computing depreciation and amortization; fair values of financial instruments; self-insurance liabilities; other accruals and allowances; income taxes; and the estimated effects of litigation and other contingencies. ~~While management believes~~

During March 2020, the World Health Organization declared a global pandemic related to the rapidly growing outbreak of a novel strain of coronavirus (“COVID-19”). The COVID-19 pandemic has significantly affected economic conditions in the United States and internationally, as national, state and local governments reacted to the public health crisis by requiring mitigation measures resulting in workforce, supply chain and other market disruptions that have created significant uncertainties in the U.S. and global economies and disrupted business activities for an uncertain period of time. Although certain jurisdictions have subsequently taken steps to lift or ease such ~~estimates are reasonable when considered~~restrictions to various degrees, such lifting or easing could subsequently be reversed, or new restrictions imposed, due to a rise in ~~conjunction with~~cases of COVID-19.

Most of the Company’s ~~consolidated~~construction services have been and currently are deemed essential under state and local pandemic mitigation orders, and all of its business segments continue to operate. Where safe and possible, the Company has generally been directed by its customers to maintain normal work schedules. Management’s top priority has been to take appropriate actions to protect the health and safety of its employees, customers and business partners, including adjusting its standard operating procedures to respond to evolving health guidelines. The COVID-19 pandemic has had a negative impact on the Company’s operations and is expected to have some continued negative impact. These impacts include lost productivity from governmental permitting approval delays, reduced crew productivity due to social distancing, other mitigation measures or other factors, the health and availability of work crews or other key personnel, including subcontractors or supply chain disruptions, and/or delayed project start dates or project shutdowns or cancellations that may be mandated or requested by governmental authorities or others, all of which could result in lower revenue or higher operating costs and/or create lower levels of overhead cost absorption.

In response to the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) was signed into law on March 27, 2020. The CARES Act provides for various tax relief and incentive measures, including provisions permitting the deferral and/or reduction of certain federal and payroll tax amounts. The Company has pursued certain of these relief provisions, and for the nine month period ended September 30, 2020, has deferred approximately $22 million of payroll taxes, net. The Company will continue to evaluate the potential effects of the CARES Act on its financial position, ~~and~~ results of operations ~~taken as a whole, actual results could differ materially from those estimates.~~and cash flows.

Management believes that it is taking appropriate steps to mitigate any potential impact to the Company; however, given the uncertainty regarding the potential effects of the COVID-19 pandemic, any future impacts cannot be quantified or predicted with specificity.

Significant Accounting Policies

The Company recognizes revenue from contracts with customers under Accounting Standards Codification (“ASC”) Topic 606 (“Topic 606”). Under Topic 606, revenue is recognized when, or as, control of promised goods and services is transferred to customers, and the amount of revenue recognized reflects the consideration to which an entity expects to be entitled in exchange for the goods and services transferred. Revenue is primarily

recognized by the Company over time utilizing the cost-to-cost measure of progress, which best depicts the continuous transfer of control of goods or services to the customer, and correspondingly, when performance obligations are satisfied for the related contracts.

Contracts. The Company derives revenue primarily from construction projects performed under: (i) master and other service agreements, which provide a menu of available services in a specific geographic territory that are utilized on an as-needed basis, and are typically priced using either a time and materials, or a fixed price per unit basis; and (ii) contracts for specific projects requiring the construction and installation of an entire infrastructure system, or specified units within an infrastructure system, which are subject to multiple pricing options, including fixed price, unit price, time and materials, or cost plus a markup. Revenue derived from projects performed under master service and other service agreements totaled ~~42% and 41%~~32% of consolidated revenue for both the three month periods ended ~~March 31,~~September 30, 2020 and 2019, and totaled 36% and 35% for the nine month periods ended September 30, 2020 and 2019, respectively.

For certain master service and other service agreements under which the Company performs installation and maintenance services, primarily for install-to-the-home service providers in its Communications segment, revenue is recognized at a point in time. This is generally when the work order has been fulfilled, which is typically the same day the work is initiated. Point in time revenue accounted for approximately 6%4% of consolidated revenue for both the three month periods ended ~~March 31,~~September 30, 2020 and 2019, and accounted for approximately 5% for both the nine month periods ended September 30, 2020 and 2019. Substantially all of the Company’s other revenue is recognized over time.

The total contract transaction price and cost estimation processes used for recognizing revenue over time under the cost-to-cost method is based on the professional knowledge and experience of the Company’s project managers, engineers and financial professionals. Management reviews estimates of total contract transaction price and total project costs on an ongoing basis. Changes in job performance, job conditions and management’s assessment of expected variable consideration are factors that influence estimates of the total contract transaction price, total costs to complete those contracts and the Company’s profit recognition. Changes in these factors could result in revisions to revenue in the period in which the revisions are determined, which could materially affect the Company’s consolidated results of operations for that period. Provisions for losses on uncompleted contracts are recorded in the period in which such losses are determined. For both the ~~three~~nine month periods ended ~~March 31,~~September 30, 2020 and 2019, project profit was affected by less than 5% as a result of changes in contract estimates included in projects that were in process as of December 31, 2019 and 2018. Revenue recognized for the three month periods ended ~~March 31,~~September 30, 2020 and 2019 as a result of changes in total contract transaction price estimates, including ~~from~~for variable consideration, from performance obligations satisfied or partially satisfied in prior periods, totaled approximately ~~$17.8~~$8.8 million and ~~$12.5~~$13.3 million, respectively, and totaled $11.5 million and $52.2 million for the nine month periods ended September 30, 2020 and 2019, respectively.

The Company may incur certain costs that can be capitalized, such as initial set-up or mobilization costs. Such costs, which are amortized over the life of the respective projects, were not material ~~in either~~as of ~~the three month periods ended March 31,~~September 30, 2020 or December 31, 2019.

Performance Obligations. A performance obligation is a contractual promise to transfer a distinct good or service to a customer, and is the unit of account under Topic 606. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when or as the performance obligation is satisfied. The vast majority of the Company’s performance obligations are completed within one year.

Remaining performance obligations represent the amount of unearned transaction prices under contracts for which work is wholly or partially unperformed, including the Company’s share of unearned transaction prices from its proportionately consolidated non-controlled joint ventures. As of ~~March 31,~~September 30, 2020, the amount of the Company’s remaining performance obligations was ~~$5.7~~$5.3 billion. Based on current expectations, the Company expects to recognize approximately ~~$4.5~~$1.6 billion of its remaining performance obligations as revenue during 2020, with the remainder to be recognized primarily in 2021.

Variable Consideration. Transaction prices for the Company’s contracts may include variable consideration, which comprises items such as change orders, claims and incentives. Management estimates variable consideration for a performance obligation utilizing estimation methods that it believes best predict the amount of consideration to which the Company will be entitled. Management’s estimates of variable consideration and the determination of whether to include estimated amounts in transaction prices are based largely on engineering studies and legal opinions, past practices with the customer, specific discussions, correspondence or preliminary negotiations with the customer and all other relevant information that is reasonably available at the time of the estimate. To the extent unapproved change orders, claims and other variable consideration reflected in transaction prices are not resolved in the Company’s favor, or to the extent incentives reflected in transaction prices are not earned, there could be reductions in, or reversals of, previously recognized revenue.

As of ~~March 31,~~September 30, 2020 and December 31, 2019, the Company included approximately ~~$35~~$50 million and $27 million, respectively, of change orders and/or claims in transaction prices for certain contracts that were in the process of being resolved in the ordinary course of business, including through negotiation, arbitration and other proceedings. These transaction price adjustments, when earned, are included within contract assets or accounts receivable, net of allowance, as appropriate. As of both ~~March 31,~~September 30, 2020 and December 31, 2019, these change orders and/or claims were primarily related to certain projects in the Company’s Oil and Gas ~~segment.~~and Electrical Transmission segments. The Company actively engages with its customers to complete the final approval process, and generally expects these processes to be completed within one year. Amounts ultimately realized upon final agreement by customers could be higher or lower than such estimated amounts.

Recently Issued Accounting Pronouncements

See the recent accounting pronouncements discussion below for information pertaining to the effects of recently adopted and other recent accounting pronouncements, as updated from the discussion in the Company’s 2019 Form 10-K.

Accounting Pronouncements Adopted in 2020

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”) to reduce diversity in practice in accounting for the costs of implementing cloud computing arrangements that are service contracts. ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for internal-use software. Accounting for the service element of the cloud computing arrangement is not affected by the new guidance. Under ASU 2018-15, amortization expense, payments for and asset balances related to such capitalized implementation costs are to be presented within the same line items of the entity’s statements of operations, cash flows and balance sheets, respectively,

as the related service fee activity and balances would be presented. ASU 2018-15, which the Company adopted on a prospective basis during the first quarter of 2020, did not have a material effect on the Company’s consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). ASU 2018-13, which is intended to improve the effectiveness of fair value measurement disclosures, modifies the disclosure requirements for certain estimates and assumptions used in determining the fair value of assets and liabilities. ASU 2018-13, which the Company adopted during the first quarter of 2020, did not have a material effect on the Company’s consolidated financial statements. See Note 4 - Fair Value of Financial Instruments for ~~certain~~ disclosure updates pertaining to significant unobservable inputs used to develop fair value estimates for certain of the Company’s Level 3 financial ~~instruments as a result of the adoption of ASU 2018-13.~~instruments.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. This ASU, together with its related clarifying ASUs (collectively, “ASU 2016-13”), introduced an expected credit loss methodology for the measurement and recognition of credit losses on most financial assets, including financial assets arising from revenue transactions, such as accounts receivable and contract assets. The ~~current~~new expected credit loss methodology, which is based on historical experience, current conditions and reasonable and supportable forecasts, replaced the ~~probable/~~incurred loss model for measuring and recognizing expected credit losses. The Company adopted this ASU in the first quarter of 2020 and incorporated this guidance into its methodology for estimating its accounts receivable allowances. ~~The adoption~~Based on historical trends, the financial condition of the Company’s customers and management’s expectations of economic and industry factors affecting the Company’s customers, ASU 2016-13 did not have a material effect on the Company’s consolidated financial statements asupon adoption. Future credit ~~losses are not expected to~~loss expectations could be ~~significant based on historical~~affected by changes in estimates or developing trends, including from changes in credit quality of the Company’s customers, changes in specific risks associated with the Company’s financial ~~condition~~assets, or from changes in management’s expectations of ~~our customers~~future economic and ~~external~~industry conditions or other factors. Management actively monitors the economic environment, including any potential effects from the COVID-19 pandemic and/or volatility in the oil and gas markets on the credit quality of the Company’s customers and/or its financial assets. For additional information about the Company’s accounts receivable and related allowances, see Note 5 - Accounts Receivable, Net of Allowance, and Contract Assets and Liabilities.

~~In March 2020, the FASB issued ASU 2020-04,~~ ~~Reference Reform Rate (Topic 848):Facilitation of the Effects of Reference Rate Reform on Financial Reporting~~ (“ASU 2020-04”) to provide temporary optional expedients and exceptions to the contract modifications, hedge relationships and other transactions affected by reference rate reform if certain criteria are met. This ASU, which was effective upon issuance and may be applied through December 31, 2022, is applicable to all contracts and hedging relationships that reference the London Interbank Offered Rate or any other reference rate expected to be discontinued. The Company is currently evaluating the impact of reference rate reform and the potential application of this guidance.

Note 2 – Earnings Per Share

Basic earnings or loss per share is computed by dividing net income attributable to MasTec by the weighted average number of common

shares outstanding for the period, which excludes non-participating unvested restricted share awards. Diluted earnings per share is computed by dividing net income attributable to MasTec by the weighted average number of fully diluted shares, as calculated under the treasury stock method, which includes the potential effect of dilutive common stock equivalents, such as issued but unvested restricted shares. If the Company reports a loss, rather than income, the computation of diluted loss per share excludes the effect of dilutive common stock equivalents, as their effect would be anti-dilutive.

The following table provides details underlying the Company’s earnings per share calculations for the periods indicated (in thousands):


	For the Three Months Ended September 30,				For the Nine Months Ended September 30,

(b)In connection with its first quarter assessment of goodwill and indefinite-lived intangible assets, management reassessed the indefinite life classification of its two pre-qualification intangible assets. Management determined that, based on changes in the assets’ characteristics, including current and expected changes in the customer mix of the associated reporting units, a finite life classification for these assets was more appropriate. As a result, in the first quarter of 2020, the Company changed the classification of these pre-qualification intangible assets from indefinite-lived to finite-lived and began amortizing them on an accelerated basis. As of March 31, 2020, the estimated remaining weighted average useful life of these assets was approximately 12 years.

(c)Represents adjustments to preliminary estimates of fair value within the measurement period of up to one year from the date of acquisition.

Quarterly Assessment for Indicators of Impairment. During the third quarter of 2020, in conjunction with the Company’s quarterly review for indicators of impairment, management performed quantitative assessments of the goodwill associated with 3 reporting units within the Oil and Gas segment. Based on the results of these assessments, management determined that the estimated fair value of 1 of the reporting units, for which the related goodwill had a carrying value of approximately $15.3 million, exceeded its carrying value by approximately 10%, and the estimated fair values of the other 2 reporting units were determined to substantially exceed their carrying values. Significant changes in the assumptions or estimates used in management’s assessment, such as a reduction in profitability and/or cash flows, could result in non-cash goodwill and indefinite-lived intangible asset impairment charges in the future.

2020 Acquisitions. For the nine month period ended September 30, 2020, MasTec completed 4 acquisitions. Through a 96%-owned consolidated subsidiary, the Company acquired all of the equity interests in a heavy civil infrastructure construction company that is included within the Company’s Clean Energy and Infrastructure segment. The Company also acquired all of the equity interests in a utility service and telecommunications construction contractor that is included within the Company’s Communications segment. In addition, the Company acquired the assets of 2 entities, 1 that specializes in wireless telecommunications and 1 that specializes in electrical transmission services.

The aggregate purchase price for these entities was composed of approximately $9.8 million in cash, net of cash acquired, with an additional $2.8 million due through 2023, subject to certain indemnification provisions, and a 5-year earn-out liability valued at approximately $7.2 million. Earn-outs are generally payable annually and are recorded within other current and other long-term liabilities in the consolidated balance sheets. As of September 30, 2020, the range of remaining potential undiscounted earn-out liabilities for the ~~three month periods ended March 31,~~ 2020 acquisitions was estimated to be up to $13 million; however, there is no maximum payment amount. Determination of the estimated fair values of the net assets acquired and ~~2019 totaled $7.4 million and $4.8 million, respectively.~~the estimated earn-out liabilities for these acquisitions was preliminary as of September 30, 2020; as a result, further adjustments to these estimates may occur.

2019 Acquisitions. During 2019, MasTec completed 6 acquisitions, 1 of which specializes in water infrastructure for pipeline companies and is included within the Company’s Oil and Gas segment, 4four of which are included within the Company’s Communications segment, including a wireline/fiber deployment construction contractor and a telecommunications company specializing in a broad range of end-to-end wireless telecommunications solutions, and 1 of which specializes in construction projects in the power industry and is included in the Company’s ~~Power Generation~~Clean Energy and ~~Industrial~~Infrastructure segment. For all but one of these acquisitions, the Company acquired all of the equity interests in the related entities. For the telecommunications company specializing in wireless telecommunications solutions, the Company acquired 96% of the entity’s equity interests, with the obligation to acquire the balance over time.

The aggregate purchase price for these entities, as adjusted, was composed of approximately $~~175.1~~176.6 million in cash, net of cash acquired, plus earn-out liabilities and a mandatorily redeemable non-controlling interest valued at approximately $~~22.2~~22.3 million and $17.8 million, respectively. The Company refers to its traditional earn-out arrangements and the mandatorily redeemable non-controlling interest collectively as ~~“Earn-outs,~~“Earn-outs.” ~~which are generally payable annually and are recorded within other current and other long-term liabilities in the consolidated balance sheets.~~ Earn-outs for the 2019 acquisitions have terms ranging from 3 to 5 years. As of ~~March 31,~~September 30, 2020, the range of remaining potential undiscounted Earn-out liabilities for the 2019 acquisitions was estimated to be between $2 million and ~~$71~~$62 million; however, there is no maximum payment amount. Determination of the estimated fair values of the net assets acquired and the estimated Earn-out liabilities for certain of these acquisitions was preliminary as of ~~March 31,~~September 30, 2020; as a result, further adjustments to these estimates may occur.

Pro Forma Financial Information and Acquisition Results. For the three month periods ended ~~March 31,~~September 30, 2020 and 2019, unaudited supplemental pro forma revenue totaled approximately ~~$1.4~~$1.7 billion and ~~$1.6~~$2.1 billion, respectively, and unaudited supplemental pro forma net income totaled approximately ~~$37.3~~$117.9 million and ~~$48.1~~$127.4 million, respectively. For the nine month periods ended September 30, 2020 and 2019, unaudited

supplemental pro forma revenue totaled approximately $4.7 billion and $5.8 billion, respectively, and unaudited supplemental pro forma net income totaled approximately $212.7 million and $300.7 million, respectively.

For the three and nine month periods ended September 30, 2019, the Company’s consolidated results of operations included acquisition-related revenue of approximately ~~$49.5~~$41.7 million and ~~$39.7~~$116.9 million, respectively, and included acquisition-related net ~~loss~~income of approximately ~~$1.2~~$1.5 million and ~~$6.1~~acquisition-related net losses of approximately $5.9 million, respectively, based on the Company’s consolidated effective tax rates. These acquisition-related results do not include the effects of acquisition costs or interest expense associated with consideration paid for the related acquisitions.

Note 4 – Fair Value of Financial Instruments

The Company’s financial instruments include cash and cash equivalents, accounts and notes receivable, cash collateral deposited with insurance carriers, life insurance assets, equity investments, certain other investments, deferred compensation plan assets and liabilities, accounts payable and other current liabilities, acquisition-related contingent consideration, mandatorily redeemable non-controlling interests and debt obligations.

Fair value is the price that would be received to sell an asset or the amount paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value guidance establishes a valuation hierarchy, which requires maximizing the use of observable inputs when measuring fair value. The three levels of inputs that may be used are: (i) Level 1 - quoted market prices in active markets for identical assets or liabilities; (ii) Level 2 - observable market-based inputs or other observable inputs; and (iii) Level 3 - significant unobservable inputs that cannot be corroborated by observable market data, which are generally determined using valuation models incorporating management estimates of market participant assumptions.

Acquisition-Related Contingent Consideration and Other Liabilities

Acquisition-related contingent consideration and other liabilities is composed of Earn-outs, which represent the estimated fair value of future amounts payable for businesses that are contingent upon the acquired business achieving certain levels of earnings in the future. As of ~~March 31,~~September 30, 2020 and December 31, 2019, the estimated fair value of the Company’s Earn-out liabilities totaled ~~$176.0~~$132.8 million and $173.2 million, respectively, of which ~~$52.9~~$47.6 million and $54.1 million, respectively, was included within other current liabilities. The fair values of the Company’s Earn-out liabilities are estimated using income approaches such as discounted cash flows or option pricing models, both of which incorporate significant inputs not observable in the market (Level 3 inputs), including management’s estimates and entity-specific assumptions, and are evaluated on an ongoing basis. Key assumptions include the discount rate, which, as of September 30, 2020, ranged from 12.0% to ~~24.7%~~23.0%, with a weighted average rate of 14.0% based on the relative fair value as of ~~March 31, 2020,~~each instrument, and probability-weighted projections of earnings before interest, taxes, depreciation and amortization (“EBITDA”). Significant changes in any of these assumptions could result in significantly higher or lower potential Earn-out liabilities. The ultimate payment amounts for the Company’s Earn-out liabilities will be determined based on the actual results achieved by the acquired businesses. As of ~~March 31,~~September 30, 2020, the range of potential undiscounted Earn-out liabilities was estimated to be between ~~$60~~$34 million and ~~$256~~$199 million; however, there is no maximum payment amount.

Earn-out activity consists primarily of additions from new business combinations; changes in the expected fair value of future payment obligations; and payments. Measurement period adjustments for Earn-out liabilities, which are fair value adjustments relating to new information obtained about the facts and circumstances existing as of the date of acquisition for a period of up to one year, are recorded to goodwill. Other revisions to the expected fair values of the Company’s traditional earn-out liabilities are reflected as other income or expense, ~~as appropriate,~~ and for the mandatorily redeemable non-controlling interest, are recorded as interest expense ~~net.~~or income. Earn-out payments, to the extent they relate to estimated liabilities as of the date of acquisition, are reflected within financing activities in the consolidated statements of cash flows. Payments in excess of acquisition date liabilities are classified within operating activities.

There were 0 additions to acquisition-related contingent consideration and other liabilities from new business combinations ~~for~~in either of the three month ~~period~~periods ended ~~March 31,~~September 30, 2020 or 2019, and for the ~~three~~nine month ~~period~~periods ended ~~March 31,~~September 30, 2020 and 2019, additions ~~from new business combinations~~ totaled ~~$15.2 million. Measurement~~$7.2 million and $16.2 million, respectively. There were 0 measurement period adjustments for the three month period ended ~~March 31,~~September 30, 2020, and measurement period adjustments for the nine month period ended September 30, 2020 totaled an increase of approximately $1.1 million, and related to a business in the Company’s Communications segment. There were 0 measurement period adjustments for the three or nine month periods ended September 30, 2019. There were 0 fair value adjustments for the three month period ended ~~March 31, 2019. Fair~~September 30, 2020, and fair value adjustments for the nine month period ended September 30, 2020 totaled a net increase of approximately ~~$1.8~~$1.7 million, ~~for the three month period ended March 31, 2020,~~ and related to businesses in the Company’s Oil and Gas and Communications segments. ~~Fair~~For the three and nine month periods ended September 30, 2019, fair value adjustments ~~including those related to finalization of completed earn-out arrangements,~~ totaled a net increase of approximately ~~$7.2~~$11.2 million ~~for the three month period ended March 31, 2019,~~and $47.6 million, respectively, and related primarily to businesses in the Company’s Oil and Gas and Communications segments. There were 0 Earn-out payments in either of the three month periods ended ~~March 31,~~September 30, 2020 or ~~2019.~~2019, and for the nine month periods ended September 30, 2020 and 2019, Earn-out payments totaled $50.4 million and $30.0 million, respectively.

The Company’s equity investments as of ~~March 31,~~September 30, 2020 include: (i) the Company’s 33% equity interests in Trans-Pecos Pipeline, LLC (“TPP”) and Comanche Trail Pipeline, LLC (“CTP,” and together with TPP, the “Waha JVs”), which are accounted for as equity method investments; (ii) a $15 million investment in Cross Country Infrastructure Services, Inc. (“CCI”); (iii) the Company’s 50% equity interests in ~~certain proportionately consolidated non-controlled contractual joint ventures;~~each of FM Technology Holdings, LLC, FM USA Holdings, LLC and All Communications Solutions Holdings, LLC, collectively, “FM Tech,” for which the Company’s aggregate investment totals approximately $16 million, and is accounted for as an equity method investment; (iv) the Company’s equity interests in American Virtual Cloud Technologies, Inc., or “AVCT” (formerly named Pensare Acquisition Corp. (“Pensare”)); (v) the Company’s interests in certain proportionately consolidated non-controlled contractual joint ventures; and ~~(v)~~(vi) certain other equity investments.

Investment Arrangements. From time to time, the Company may participate in selected investment or strategic arrangements, including equity interests in various business entities and participation in contractual joint ~~ventures, some of which~~ventures. The Company’s investment and strategic arrangements may involve the extension of loans or other types of financing ~~arrangements. As~~arrangements, including approximately $6 million of ~~March 31, 2020, the~~financing commitments as of September 30, 2020. The Company has determined that certain of its investment arrangements ~~were~~are variable interest entities (“VIEs”). ~~Except~~As of September 30, 2020, except for one individually insignificant VIE, the Company does not have the power to direct the primary activities that most significantly impact the economic performance of its VIEs nor is it the primary beneficiary. Accordingly, except for the previously mentioned VIE, the Company’s VIEs are not consolidated.

Equity investments, other than those accounted for as equity method investments or those that are proportionately consolidated, are measured at fair value if their fair values are readily determinable. Equity investments that do not have readily determinable fair values are measured at cost, adjusted for changes from observable market transactions, if any, less impairment (“adjusted cost basis”). As of ~~March 31,~~September 30, 2020 and December 31, 2019, the aggregate carrying value of the Company’s equity investments, ~~totaled approximately $195 million and $196 million, respectively,~~ including ~~approximately $18 million of~~ equity investments measured on an adjusted cost basis, astotaled approximately $205 million and $196 million, respectively. As of ~~both March 31,~~September 30, 2020 and December 31, ~~2019.~~2019, equity investments measured on an adjusted cost basis, including the Company’s investment in CCI, totaled approximately $17 million and $18 million, respectively. There were 0 ~~impairments of, or~~ material changes in the fair ~~value~~values of, or impairments related to, these investments during either of the ~~three~~nine month periods ended ~~March 31,~~September 30, 2020 or 2019.

The Waha JVs. The Waha JVs own and operate ~~2 pipelines and a header system~~certain pipeline infrastructure that ~~transport~~transports natural gas to the Mexican border for export. Equity in earnings related to the Company’s proportionate share of income from the Waha JVs, which is included within the Company’s Other segment, totaled approximately ~~$7.6~~$7.7 million and ~~$6.3~~$6.9 million for the three month periods ended ~~March 31,~~September 30, 2020 and 2019, respectively, and totaled $22.9 million and $19.8 million for the nine month periods ended September 30, 2020 and 2019, respectively. Cumulative undistributed earnings from the Waha JVs, which represents cumulative equity in earnings for the Waha JVs less distributions of earnings, totaled ~~$53.1~~$60.7 million as of ~~March 31,~~September 30, 2020. Distributions of earnings from the Waha JVs, which are included within operating cash flows, totaled ~~$2.6~~$2.4 million and ~~$3.9~~$1.5 million for the three month periods ended ~~March 31,~~September 30, 2020 and 2019, respectively, and totaled $10.2 million and $7.5 million for the nine month periods ended September 30, 2020 and 2019, respectively. The Company’s net investment in the Waha JVs, which differs from its proportionate share of the net assets of the Waha JVs due primarily to capitalized investment costs, totaled approximately ~~$156~~$165 million and $174 million as of ~~March 31,~~September 30, 2020 and December 31, 2019, respectively.

The Waha JVs are party to separate non-recourse financing facilities, each of which are secured by pledges of the equity interests in the respective entities, as well as a first lien security interest over virtually all of their assets. The Waha JVs are also party to certain interest rate swaps, which are accounted for as qualifying cash flow hedges. The Company reflects its proportionate share of any unrealized fair market value gains or losses from fluctuations in interest rates associated with these swaps within other comprehensive income or loss, as appropriate. For the three and nine month periods ended ~~March 31,~~September 30, 2020, the Company’s proportionate share of unrecognized unrealized activity on these interest rate swaps totaled gains of approximately $2.5 million and losses of approximately $29.5 million, respectively, or gains of $1.9 million and losses of $22.4 million, net of tax, respectively. For the three and nine month periods ended September 30, 2019, the Company’s proportionate share of unrecognized unrealized activity on these interest rate swaps totaled losses of approximately ~~$30.3~~$9.4 million and $28.2 million, respectively, or ~~$23.0~~$7.1 million ~~net of tax,~~ and ~~$7.2 million, or $5.5~~$21.3 million, net of tax, respectively.

Other Investments. ~~During 2017, the~~The Company ~~purchased approximately 4%~~has investments in AVCT. These investments include (i) shares of ~~the~~AVCT common stock, which are equity securities, (ii) warrants for the purchase of ~~Pensare, a special purpose acquisition company focusing on transactions in the telecommunications industry,~~AVCT common stock, which are derivative financial instruments, and ~~warrants to purchase an additional 2.0 million~~(iii) debentures that are convertible into shares of ~~Pensare~~AVCT common stock, ~~(the “initial warrants”)~~which are available-for-sale securities. As of September 30, 2020 and December 31, 2019, the Company’s ownership interest in AVCT’s common stock, represented by the AVCT shares, totaled approximately 9% and 21%, ~~for $2.0 million.~~respectively, and its aggregate ownership interest, assuming the exercise and conversion of all legally exercisable warrants and convertible debt into AVCT common stock, totaled approximately 22% and 21%, respectively. José R. Mas, MasTec’s Chief Executive Officer, was a director of Pensare through the end of March 2020. The ~~shares~~Company paid an aggregate of common stock purchased by MasTec are not transferable or salable until one year after Pensare successfully completes a business combination transaction, with limited exceptions. The initial warrants are exercisable at a purchase price of $11.50 per share beginning thirty days after the first date Pensare successfully completes a business combination transaction. In April 2020, Pensare completed a business combination transaction with Stratos Management Systems, Inc. andapproximately $5 million for its ~~operating companies, which do business as Computex Technology Solutions (collectively, “Computex”), an information technology service provider, and~~investments in ~~connection therewith, Pensare changed its name to American Virtual Cloud Technologies, Inc. (“AVCT”). In addition to other investors in a private placement conducted by~~ AVCT, ~~contemporaneously with the completion of the business combination transaction in April 2020, MasTec invested $3.0 million in exchange for 3,000 units of AVCT securities, each~~all of which ~~consists of $1,000~~are included within other long-term assets in ~~principal amount of AVCT Series A convertible debentures, convertible~~the Company’s consolidated financial statements.

The convertible debentures may be converted in whole or in part at any time from April 7, 2020 until full payment thereof, subject to mandatory conversion of the convertible debentures, pursuant to the terms thereof, and the AVCT warrants are exercisable at any time from April 7, 2020 through April 7, 2025. Due to the completion of the Computex business combination, the initial warrants will be exercisable beginning May 7, 2020, until the earlier to occur of April 7, 2025 and the liquidation of AVCT, subject to extension.

Prior to completion of the Computex acquisition, certain holders of AVCT’s redeemable common stock elected to redeem their shares, the effect of which, after giving effect to the additional investment described above, was to increase the Company’s beneficial ownership interest in AVCT common stock to approximately 21%.securities law restrictions. The Company does not have the ability to exert significant influence over the operating and financial policies of AVCT.

As of September 30, 2020, the aggregate fair value of the Company’s investments in AVCT ~~therefore,~~approximated $11 million. For the ~~shares are measured~~three and nine month periods ended September 30, 2020, the Company recorded unrealized fair value measurement gains, net, on ~~an adjusted cost basis. The initial warrants, which are derivative financial instruments,~~the AVCT securities within other income totaling approximately $0.9 million and $4.7 million, respectively, primarily related to the AVCT shares, for which the fair value was ~~not readily determinable~~determined based on the market price of identical securities, adjusted for the restrictions on sale, which is a Level 3 input. Unrealized fair value measurement gains on the AVCT convertible debentures recognized within other comprehensive income, as ofdetermined based on Monte Carlo simulations, which is a Level 3 input, totaled approximately $0.9 million for both ~~March 31, 2020~~the three and nine month periods ended September 30, 2020. As of December 31, 2019, ~~due to~~ the ~~nature of the restrictions, are included within other long-term assets in the Company’s consolidated financial statements.

Contract billings represent the amount of performance obligations that have been billed but have not yet ~~collected. Contract~~been collected, whereas contract assets consist of unbilled receivables and retainage. Unbilled receivables represent the estimated value of unbilled work for projects with performance obligations recognized over time. Retainage represents a portion of the contract amount that has been billed, but for which the contract allows the customer to retain a portion of the billed amount until final contract settlement (generally, from 5% to 10% of contract billings). For the three and nine month ~~period~~periods ended ~~March 31,~~September 30, 2020, provisions for credit losses totaled ~~$1.6~~$1.9 million and ~~impairment~~$14.2 million, respectively, including potential credit losses resulting from current economic uncertainty.

In those instances, the Company recognizes a liability for advance billings in excess of revenue recognized, which is referred to as deferred revenue. Contract liabilities also include the amount of any accrued project losses. Total contract liabilities, including accrued project losses, totaled approximately ~~$204.3~~$368.2 million and $206.2 million as of ~~March 31,~~September 30, 2020 and December 31, 2019, respectively, of which deferred revenue comprised approximately ~~$181.4~~$349.1 million and $184.1 million, respectively.

Issuance of 4.50% Senior Notes and Repurchase and Redemption of 4.875% Senior Notes

On August 4, 2020, the Company issued $600 million aggregate principal amount of senior unsecured notes due August 15, 2028, which bear interest at a rate of 4.50% (the “4.50% Senior Notes”), at par in a private offering (the “Private Offering”). Interest on the 4.50% Senior Notes is payable semiannually in arrears on February 15 and August 15 of each year, beginning on February 15, 2021. The 4.50% Senior Notes are general senior unsecured obligations of the Company, and rank equal in right of payment with all of the Company’s existing and future senior unsecured indebtedness and senior in right of payment to all of the Company’s existing and future subordinated indebtedness. The 4.50% Senior Notes are effectively subordinated to all secured indebtedness of the Company, including its existing credit facilities, to the extent of the value of the assets securing such indebtedness. The 4.50% Senior Notes are fully and unconditionally guaranteed on a senior unsecured, joint and several basis by the Company’s wholly-owned domestic restricted subsidiaries that guarantee its existing credit facilities, subject to certain exceptions.

The Company used a portion of the proceeds from the Private Offering to redeem all $400 million of its outstanding 4.875% Senior Notes due 2023 (the “ 4.875% Senior Notes”) on August 19, 2020 (the “Redemption Date”) at a redemption price equal to 100.813% of the principal amount of the 4.875% Senior Notes redeemed, plus accrued and unpaid interest to, but not including, the Redemption Date. The remaining net proceeds from the Private Offering were primarily used to repay revolving loans under the Company’s existing credit facilities.

The Company has the option to redeem all or a portion of the 4.50% Senior Notes at any time on or after August 15, 2023 at the redemption prices specified in the indenture that governs the 4.50% Senior Notes (the “4.50% Senior Notes Indenture”), plus accrued and unpaid interest, if any, to (but excluding) the redemption date. In addition, at any time prior to August 15, 2023, the Company may redeem all or a part of the 4.50% Senior Notes at a redemption price equal to 100% of the principal amount of the 4.50% Senior Notes redeemed, plus accrued and unpaid interest, if any, to (but excluding) the redemption date, plus a “make-whole” premium. Further, prior to August 15, 2023, the Company may redeem up to 40% of the aggregate principal amount of the 4.50% Senior Notes using the net cash proceeds of certain equity offerings, at a redemption price equal to 104.500% of the principal amount of the 4.50% Senior Notes redeemed, plus accrued and unpaid interest, if any, to (but excluding) the date of redemption, subject to certain conditions.

If the Company undergoes a change of control, as defined in the 4.50% Senior Notes Indenture, the Company must make an offer to repurchase all of the 4.50% Senior Notes then outstanding at a price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to (but excluding) the date of repurchase.

The 4.50% Senior Notes Indenture, among other things, generally limits the ability of the Company and certain of its subsidiaries, subject to certain exceptions, to (i) create liens, (ii) pay dividends, (iii) acquire shares of capital stock, (iv) make certain investments and (v) effect mergers. The 4.50% Senior Notes Indenture provides for customary events of default, subject to customary grace and cure periods. Generally, if an event of default occurs and is continuing, the trustee or holders of at least 30% of the 4.50% Senior Notes then outstanding may declare the principal of, premium, if any, and accrued interest on all of the 4.50% Senior Notes immediately due and payable. Financing costs incurred in connection with the issuance of the 4.50% Senior Notes totaled approximately $8.9 million. These deferred financing costs, which are reflected as a reduction of the carrying amount of the 4.50% Senior Notes, will be amortized over the term of the 4.50% Senior Notes using the effective interest method.

Management determined that the repurchase and redemption of the Company’s 4.875% Senior Notes should be accounted for as a debt extinguishment. Accordingly, the Company recorded a pre-tax debt extinguishment loss of approximately $5.6 million in the third quarter of 2020, including $3.3 million of early repayment premiums and $2.3 million of unamortized deferred financing costs. This loss is separately disclosed within the Company’s consolidated statements of operations.

Note 10 – Other Retirement Plans

Multiemployer Plans. Certain of MasTec’s subsidiaries, including certain subsidiaries in Canada, contribute amounts to multiemployer pension and other multiemployer benefit plans and trusts (“MEPPs”), which are recorded as a component of employee wages and salaries within costs of revenue, excluding depreciation and amortization. Contributions are generally based on fixed amounts per hour per employee for employees covered under these plans. Multiemployer plan contribution rates are determined annually and assessed on a “pay-as-you-go” basis based on union employee payrolls. Union payrolls cannot be determined for future periods because the number of union employees employed at a given time, and the plans in which they participate, vary depending upon the location and number of ongoing projects and the need for union resources in connection with those projects. Total contributions to multiemployer plans and the related number of employees covered by these plans for the periods indicated were as follows:

The fluctuations in the number of employees covered under multiemployer plans and related contributions in the table above related primarily to timing of activity for the Company’s union resource-based projects, the majority of which are within its oil and gas operations.

Note 11 – Equity

Share Activity

The Company’s share repurchase programs provide for the repurchase of shares of MasTec common stock from time to time in open market transactions or in ~~privately-negotiated~~privately negotiated transactions in accordance with applicable securities laws. The timing and the amount of any repurchases is determined based on market conditions, legal requirements, cash flow and liquidity needs and other factors. The Company’s share repurchase programs do not have an expiration date and may be modified or suspended at any time at the Company’s discretion. Share repurchases, which are recorded at cost and are held in the Company’s treasury, are funded with available cash or with availability under the Credit Facility. The Company may use either authorized and unissued shares or treasury shares to meet share issuance requirements. Treasury stock is recorded at cost.

See Note 4 - Fair Value of Financial Instruments for additional information pertaining to the Waha JV swaps and AVCT convertible debentures.

Note 12 – Income Taxes

In determining the quarterly provision for income taxes, management uses an estimated annual effective tax rate based on forecasted annual pre-tax income, permanent tax differences, statutory tax rates and tax planning opportunities in the various jurisdictions in which the Company operates.

The effect of significant discrete items is separately recognized in the quarter(s) in which they occur. For the three month periods ended ~~March 31,~~September 30, 2020 and 2019, the Company’s consolidated effective tax rates were ~~1.2%~~25.7% and ~~21.8%~~25.0%, respectively. For the nine month periods ended September 30, 2020 and 2019, the Company’s consolidated effective tax rates were 22.7% and 24.5%, respectively. The Company’s effective tax rate for the ~~three~~nine month period ended ~~March 31,~~September 30, 2020 ~~included a benefit~~benefited from the release of approximately $9.6 million ~~related to the release~~ of certain valuation allowances on Canadian deferred tax assets that were no longer ~~necessary.~~necessary, as well as from adjustments related to the finalization of the Company’s 2019 tax returns. For the ~~three~~nine month period ended ~~March 31,~~September 30, 2019, the Company’s effective tax rate was favorably affected by reduced foreign earnings, the recognition of ~~$2.3~~$2.3 million of excess tax benefits from the vesting of share-based awards, ~~and reduced foreign earnings.~~

~~In response to~~adjustments from the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law on March 27, 2020. The CARES Act, among other things, includes tax provisions relating to refundable payroll tax credits, defermentfinalization of employer’s social security payments, net operating loss utilization and carryback periods, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property (QIP). At this time, management does not believe that the CARES Act will have a material impact on the Company’s ~~income~~2018 tax ~~provision for 2020. The Company will continue to evaluate~~returns and the ~~impact~~effects of ~~the CARES Act on its financial position, results of operations and cash flows.~~foreign tax rate changes.

Note 13 – Segments and Related Information

Segment Discussion

The Company manages its operations under 5 operating segments, which represent its 5 reportable segments: (1) Communications; (2) Oil and Gas; (3) Electrical Transmission; (4) ~~Power Generation~~Clean Energy and ~~Industrial~~Infrastructure and (5) Other. This structure is generally focused on broad end-user markets for the Company’s labor-based construction services. All 5 reportable segments derive their revenue from the engineering, installation and maintenance of infrastructure, primarily in North America.

The Communications segment performs engineering, construction, maintenance and customer fulfillment activities related to communications infrastructure, primarily for wireless and wireline/fiber communications and install-to-the-home customers, and, to a lesser extent, infrastructure for utilities, among others. The Company performs engineering, construction and maintenance services for oil and natural gas pipelines and processing facilities for the energy and utilities industries through its Oil and Gas segment. The Electrical Transmission segment primarily serves the energy and utility industries through the engineering, construction and maintenance of electrical transmission lines and substations. The ~~Power Generation~~Clean Energy and ~~Industrial~~Infrastructure segment primarily serves energy, utility and other end-markets through the installation and construction of power facilities, including from renewable sources, related electrical transmission infrastructure, ethanol/biofuel facilities and various types of heavy civil and industrial infrastructure. The Other segment includes certain equity investees, the services of which vary from those provided by the Company’s primary segments, as well as other small business units that perform construction and other services for a variety of international end-markets.

Earnings before interest, taxes, depreciation and amortization (“EBITDA”) is the measure of profitability used by management to manage its segments and, accordingly, in its segment reporting. As appropriate, the Company supplements the reporting of its consolidated financial information determined in accordance with U.S. GAAP with certain non-U.S. GAAP financial measures, including EBITDA. The Company believes these non-U.S. GAAP measures provide meaningful information and help investors understand the Company’s financial results and assess its prospects for future performance. The Company uses EBITDA to evaluate its performance, both internally and as compared with its peers, because it excludes certain items that may not be indicative of the Company’s core operating results for its reportable segments, as well as items that can vary widely across different industries or among companies within the same industry. Segment EBITDA is calculated in a manner consistent with consolidated EBITDA.

Summarized financial information for MasTec’s reportable segments is presented and reconciled to consolidated financial information for total MasTec in the following tables, including a reconciliation of consolidated income before income taxes to EBITDA, all of which are presented in millions. The tables below may contain slight summation differences due to rounding.

Note 14 – Commitments and Contingencies

MasTec is subject to a variety of legal cases, claims and other disputes that arise from time to time in the ordinary course of its business, including project contract price and acquisition purchase price disputes. MasTec cannot provide assurance that it will be successful in recovering all or

any of the potential damages it has claimed or in defending claims against the Company. The outcome of such cases, claims and disputes cannot be predicted with certainty and an unfavorable resolution of one or more of them could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows.

~~COVID-19 Pandemic~~

During March 2020, the World Health Organization declared a global pandemic related to the rapidly growing outbreak of a novel strain of coronavirus (COVID-19). The COVID-19 pandemic has significantly affected economic conditions in the United States and internationally as national, state and local governments reacted to the public health crisis by requiring mitigation measures that have disrupted business activities for an uncertain period of time. The effects of the COVID-19 pandemic could affect the Company’s future business activities and financial results, including from governmental permitting approval delays, reduced crew productivity, higher operating costs and lower levels of overhead cost absorption and/or delayed project start dates or project shutdowns that may be requested or mandated by governmental authorities or others.

The effects of the COVID-19 pandemic on the Company’s financial results for the three month period ended March 31, 2020 were limited. Most of the Company’s construction services are currently deemed essential under governmental mitigation orders and substantially all of its business segments continue to operate. Management’s top priority has been to take appropriate actions to protect the health and safety of its employees, customers and business partners, including adjusting its standard operating procedures to respond to evolving health guidelines. Management believes that it is taking appropriate steps to mitigate any potential impact to the Company; however, given the uncertainty regarding the potential effects of the COVID-19 pandemic, any future impacts cannot be quantified or predicted with specificity.

Other Commitments and Contingencies

Leases. In the ordinary course of business, the Company enters into non-cancelable operating leases for certain of its facility, vehicle and equipment needs, including related party leases. See Note 8 - Lease Obligations and Note 15 - Related Party Transactions.

Letters of Credit. In the ordinary course of business, the Company is required to post letters of credit for its insurance carriers and surety bond providers and in support of performance under certain contracts as well as certain obligations associated with the Company’s equity investments and other strategic arrangements, including its variable interest entities. 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 under certain conditions. If this were to occur, the Company would be required to reimburse the issuer of the letter of credit, which, depending upon the circumstances, could result in a charge to earnings. As of ~~March 31,~~September 30, 2020 and December 31, 2019, there were ~~$161.2~~$153.0 million and $115.1 million, respectively, of letters of credit issued under the Company’s credit facilities. The Company is not aware of any material claims relating to its outstanding letters of credit as of ~~March 31,~~September 30, 2020 or December 31, 2019.

Performance and Payment Bonds. In the ordinary course of business, MasTec is required by certain customers to provide performance and payment bonds for contractual commitments related to its projects. These bonds provide a guarantee to the customer that the Company will perform under the terms of a contract and that the Company will pay its subcontractors and vendors. If the Company fails to perform under a contract or to pay its subcontractors and vendors, the customer may demand that the surety make payments or provide services under the bond. The Company must reimburse the surety for expenses or outlays it incurs. As of ~~March 31,~~September 30, 2020 and December 31, 2019, outstanding performance and payment bonds approximated ~~$577.5~~$640.1 million and $551.4 million, respectively, and estimated costs to complete projects secured by these bonds totaled ~~$162.8~~$226.3 million and $194.7 million as of ~~March 31,~~September 30, 2020 and December 31, 2019, respectively.

Investment and Strategic Arrangements. The Company holds undivided interests, ranging from 85% to 90%, in multiple proportionately consolidated non-controlled contractual joint ventures that provide infrastructure construction services for electrical transmission ~~projects.~~projects, as well as a 50% undivided interest in a civil construction project. Income and/or losses incurred by these joint ventures are generally shared proportionally by the respective joint venture members, with the members of the joint ventures jointly and severally liable for all of the obligations of the joint venture. The respective joint venture agreements provide that each joint venture partner indemnify the other party for any liabilities incurred by such joint venture in excess of its ratable portion of such liabilities. Thus, it is possible that the Company could be required to pay or perform obligations in excess of its share if the other joint venture partners fail or refuse to pay or perform their respective share of the obligations. As of ~~March 31,~~September 30, 2020, the Company was not aware of ~~circumstances that would reasonably lead to~~any material future claims against it in connection with these arrangements. Included in the Company’s cash balances as of ~~March 31,~~September 30, 2020 and December 31, 2019 are amounts held by entities that are proportionately consolidated totaling ~~$9.1~~$8.4 million and $13.1 million, respectively. These amounts are available to support the operations of those entities, but are not available for the Company’s other operations.

The Company has other investment and strategic arrangements, under which it may incur costs or provide financing, performance, financial and/or other guarantees. See Note 4 - Fair Value of Financial Instruments regarding the Company’s other investment and strategic arrangements.

Self-Insurance. MasTec maintains insurance policies for workers’ compensation, general liability and automobile liability, which are subject to per claim deductibles. The Company is self-insured up to the amount of the deductible. The Company also maintains excess umbrella coverage. As of ~~March 31,~~September 30, 2020 and December 31, 2019, MasTec’s estimated liability for unpaid claims and associated expenses, including incurred but not reported losses related to these policies, totaled ~~$125.3~~$129.0 million and $123.4 million, respectively, of which ~~$85.8~~$85.9 million and $87.3 million, respectively, were reflected within other long-term liabilities in the consolidated balance sheets. MasTec also maintains an insurance policy with respect to employee group medical claims, which is subject to annual per employee maximum losses. MasTec’s estimated liability for employee group medical claims totaled ~~$4.7~~$4.1 million and $4.2 million as of ~~March 31,~~September 30, 2020 and December 31, 2019, respectively.

The Company is required to post collateral, generally in the form of letters of credit, surety bonds and cash to certain of its insurance carriers. Insurance-related letters of credit for the Company’s workers’ compensation, general liability and automobile liability policies amounted to $59.3 million and $64.0 million as of ~~both March 31,~~September 30, 2020 and December 31, ~~2019.~~2019, respectively. Outstanding surety bonds related to self-insurance programs amounted to $37.4 million and $38.5 million as of ~~both March 31,~~September 30, 2020 and December 31, ~~2019.~~2019, respectively.

Collective Bargaining Agreements and Multiemployer Plans. As discussed in Note 10 - Other Retirement Plans, certain of MasTec’s subsidiaries are party to various collective bargaining agreements with unions representing certain of their employees, which require the Company to

pay specified wages, provide certain benefits and contribute certain amounts to MEPPs. The Employee Retirement Income Security Act of 1974, as amended by the Multiemployer Pension Plan Amendments Act of 1980 (collectively, “ERISA”), which governs U.S.-registered MEPPs, subjects employers to substantial liabilities in the event of an employer’s complete or partial withdrawal from, or upon termination of, such plans.

The Company currently contributes, and in the past, has contributed to, plans that are underfunded, and, therefore, could have potential liability associated with a voluntary or involuntary withdrawal from, or termination of, these plans. As of ~~March 31,~~September 30, 2020, the Company does not have plans to withdraw from, and is not aware of circumstances that would reasonably lead to material claims against it, in connection with the MEPPs in which it participates. There can be no assurance, however, that the Company will not be assessed liabilities in the future, including in the form of a surcharge on future benefit contributions or increased contributions on underfunded plans. The amount the Company could be obligated to pay or contribute in the future cannot be estimated, as these amounts are based on future levels of work of the union employees covered by these plans, investment returns, which could be negatively affected by economic and market conditions, and the level of underfunding of such plans.

Indemnities. The Company generally indemnifies its customers for the services it provides under its contracts, as well as other specified liabilities, which may subject the Company to indemnity claims, liabilities and related litigation. As of ~~March 31,~~September 30, 2020 and December 31, 2019, the Company was not aware of any material asserted or unasserted claims in connection with these indemnity obligations.

Other Guarantees. InFrom time to time in the ordinary course of its business, ~~from time to time,~~ MasTec guarantees the obligations of its subsidiaries, including obligations under certain contracts with customers, certain lease obligations and in some states, obligations in connection with obtaining contractors’ licenses. MasTec has also issued performance and other guarantees in connection with certain of its equity investments. MasTec also generally warrants the work it performs for a one to two year period following substantial completion of a project. Much of the work performed by the Company is evaluated for defects shortly after the work is completed. ~~Warranty claims have historically not been material. However, if~~If warranty claims occur, the Company could be required to repair or replace warrantied items, or, if customers elect to repair or replace the warrantied item using the services of another provider, the Company could be required to pay for the cost of the repair or replacement. Warranty claims have historically not been material.

Concentrations of Risk. The Company had approximately ~~295~~435 customers for the ~~three~~nine month period ended ~~March 31,~~September 30, 2020. As of ~~March 31,~~September 30, 2020, 2 customers each accounted for approximately ~~16%~~15% and ~~15%~~13%, respectively, of the Company’s consolidated net accounts receivable position, which represents accounts receivable, net, less deferred revenue. As of December 31, 2019, 3 customers each accounted for approximately 17%, 13% and 11%, respectively, of the Company’s consolidated net accounts receivable position. In addition, the Company derived ~~62%~~63% and 65%, respectively, of its revenue from its top 10 customers for ~~both~~ the three month periods ended ~~March 31,~~September 30, 2020 and 2019, and derived 61% and 63%, respectively, of its revenue from its top 10 customers for the nine month periods ended September 30, 2020 and 2019.

~~ITEM 2.~~	~~MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS~~

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following is a discussion of our business, financial condition and results of operations as of and for the three and nine month periods ended ~~March 31,~~September 30, 2020 and ~~2019~~.2019. This discussion and analysis should be read in conjunction with our consolidated financial statements and notes thereto in Item 1 of this Quarterly Report on Form 10-Q (this “Form 10-Q”), and the audited consolidated financial statements, accompanying notes and Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) contained in our 2019 Form 10-K. In this MD&A, “$” means U.S. dollars unless specified otherwise.

Impact of the COVID-19 Pandemic

During March 2020, a global pandemic was declared by the World Health Organization related to the rapidly growing outbreak of a novel strain of coronavirus ~~(COVID-19)~~(“COVID-19”). The COVID-19 pandemic has significantly affected economic conditions in the United States and internationally, ~~accelerating during the first half of March and continuing into April,~~ as federal, state and local governments reacted to the public health crisis with mitigation measures, including "stay-at-home," "shelter-in-place," social distancing, travel restrictions and other similar orders, which has resulted in workforce, supply chain and production disruptions, along with reduced demand and spending in many industry sectors, creating significant uncertainties in the U.S. economy. Although there has been some reduction of certain of these restrictions on economic and social activities, these restrictions could subsequently be reversed, or new restrictions imposed, due to a rise in cases of COVID-19. It is currently unclear whether additional or renewed restrictions will be implemented, the extent of such restrictions and/or how long an economic recovery could take. The extent to which the COVID-19 pandemic could affect our business, operations and financial results will depend upon numerous evolving factors that we may not be able to accurately ~~predict.~~

~~The effects~~predict, including the length and extent of the ~~pandemic on our financial results for the three month period ended March 31, 2020 were limited. To date, most~~economic and market disruption.

Most of our construction services have been and currently are ~~currently~~ deemed essential under state and local pandemic mitigation orders and all of our business segments continue to operate.As our services have been deemed essential, our customers have generally directed us, where safe and possible, to maintain normal work schedules. Our business model has, thus far, proven resilient, and we continue to make efforts to adapt to the changing operational and economic environment that has resulted from the COVID-19 pandemic. Our top priority has been to take appropriate actions to protect the health and safety of our employees, customers and business partners. We have adjusted our standard operating procedures within our business operations to ensure ~~continued~~ employee and customer safety and are continually monitoring evolving health guidelines and responding to changes as appropriate. These procedures include implementation of specialized training programs, appropriate social distancing ~~programs~~procedures and required use of ~~certain~~ personal protective equipment for our crew operations, as well as appropriate sanitation measures for key equipment and facilities. We have ~~also~~restricted non-essential business travel and incorporated ~~work at home~~work-at-home programs ~~where necessary~~as appropriate for our administrative offices. For in-office operations, appropriate safety and social distancing measures have been incorporated. We have also developed human resource guidance to assist our employees. In certain locations where our operations have experienced challenges as a result of the pandemic, we are collaborating with our customers to minimize potential service disruptions and operational impacts.

The ~~impact of the~~ COVID-19 pandemic has had, and is expected to continue to have, a negative impact on our operations in 2020, and may continue to affect our future business activities for an indefinite period of time. These impacts ~~may~~ include lost productivity from governmental permitting approval delays, reduced crew productivity due to social distancing, other mitigation measures or other factors, ~~higher operating costs~~the health and ~~lower levels~~availability of ~~overhead cost absorption,~~work crews or other key personnel, including subcontractors or supply chain disruptions, and/or delayed project start dates or project shutdowns or cancellations that may be ~~requested~~mandated or ~~mandated~~requested by governmental authorities or ~~others.~~others, all of which could result in lower revenue or higher operating costs and/or create lower levels of overhead cost absorption. We continue to actively monitor the effects of the COVID-19 pandemic on our operations and may take further actions, as necessary, that we determine to be in the best interests of our employees, customers, business partners and stakeholders, or as required by federal, state, or local authorities. Additionally, disruptions in economic activity as a result of the COVID-19 pandemic have had, and may continue to have adverse effects across our end markets, particularly in the oil and gas sector. To the extent that future business activities are adversely affected by the pandemic, we intend to take appropriate actions designed to mitigate these ~~impacts; however, there can be no assurance that we will be successful in these efforts.~~

~~Additionally, potential disruptions in future economic activity as a result of the COVID-19 pandemic may have adverse effects across our end markets, but given~~impacts. Given the uncertainty regarding the magnitude and duration of the pandemic’s effects, we are unable to predict with specificity or quantify any potential future impact on our business, financial condition and/or results of operations.

In response to the COVID-19 pandemic, on March 27, 2020, the CARES Act was signed into law. The CARES Act provides for various tax relief and incentive measures. At this time, we do not believe that the CARES Act will have a material impact on our results of operations in 2020. Under certain of the relief provisions of the CARES Act, we deferred approximately $22 million of payroll taxes, net, for the nine month period ended September 30, 2020, of which half are due by December 31, 2021, with the remainder due by December 31, 2022. We currently intend to continue to defer payroll taxes through December 31, 2020, as permitted under the CARES Act. We continue to monitor all available federal and other COVID-19 relief provisions to determine our qualification for, and the usefulness to us, of any such relief measures.

As of ~~March 31,~~September 30, 2020, we ~~maintain~~maintained a strong balance sheet, have strong relationships with our banking partners and ~~have~~had ample liquidity totaling approximately ~~$946 million,~~$1.4 billion, comprising ~~$874 million~~$1.2 billion of availability under our ~~credit facility~~Credit Facility and ~~$72~~$238 million of cash. We believe that our financial position, strong cash flows and operational strengths will enable us to manage the current challenges and uncertainties resulting from the COVID-19 pandemic. Our business operations typically generate significant cash flow, affording us the flexibility to invest strategically in our efforts to maximize shareholder value through mergers and acquisitions, share repurchases and capital expenditures. We are carefully managing liquidity and are monitoring any potential effects from the pandemic on our financial results, cash flows and/or working capital and intend to take appropriate actions in efforts to mitigate any ~~impacts; however, there can be no assurance that we will be successful in these efforts.~~impacts.

Business Overview

We are a leading infrastructure construction company operating mainly throughout North America across a range of industries. Our primary activities include the engineering, building, installation, maintenance and upgrade of communications, energy, utility and other infrastructure, such as: wireless, wireline/fiber and customer fulfillment activities; ~~petroleum and natural gas~~ pipeline infrastructure; electrical utility transmission and distribution; power generation, including from clean energy and renewable sources; heavy civil; and industrial infrastructure. Our customers are primarily in these industries. Including our predecessor companies, we have been in business for over 90 years. For the twelve month period ended ~~March 31,~~September 30, 2020, we had an average of approximately ~~20,000~~18,000 employees and ~~380~~390 locations. We offer our services primarily under the MasTec service mark. We have been consistently ranked among the top specialty contractors by Engineering News-Record for the past several years.

We provide our services to a diversified base of customers. We often provide services under master service and other service agreements, which are generally multi-year agreements. The remainder of our work is generated pursuant to contracts for specific projects or jobs that require the construction or installation of an entire infrastructure system or specified units within an infrastructure system.

We manage our operations under five operating segments, which represent our five reportable segments: (1) Communications; (2) Oil and Gas; (3) Electrical Transmission; (4) ~~Power Generation~~Clean Energy and ~~Industrial~~Infrastructure and (5) Other. This structure is generally focused on broad end-user markets for our labor-based construction services. During the second quarter of 2020, we renamed our Power Generation and Industrial segment as the Clean Energy and Infrastructure segment to better represent the nature of the segment’s operations, end markets and customer characteristics. There was no change to the composition of the segment or its historical results. See Note 13 - Segments and Related Information and Note 14 - Commitments and Contingencies in the notes to the consolidated financial statements, which are incorporated by reference, for segment related information and significant customer concentrations.

Backlog

Estimated backlog represents the amount of revenue we expect to realize over the next 18 months from future work on uncompleted construction contracts, including new contracts under which work has not begun, as well as revenue from change orders and renewal options. Our estimated backlog also includes amounts under master service and other service agreements and includes our proportionate share of estimated revenue from proportionately consolidated non-controlled contractual joint ventures. Estimated backlog for work under master service and other service agreements is determined based on historical trends, anticipated seasonal impacts, experience from similar projects and estimates of customer demand based on communications with our customers. Based on current expectations of our customers’ requirements, we expect to realize approximately ~~70%~~25% of our estimated ~~March 31,~~September 30, 2020 backlog in 2020. The following table presents 18-month estimated backlog by reportable segment, as of the dates indicated:

$ 8,000

~~Approximately 40%~~As of September 30, 2020, 46% of our backlog ~~as of March 31, 2020~~ is attributable to amounts under master service or other service agreements, pursuant to which our customers are not contractually committed to purchase a minimum amount of services. Most of these agreements can be canceled on short or no advance notice. Timing of revenue for construction and installation projects included in our backlog can be subject to change as a result of customer, ~~delays or cancellations,~~ regulatory or other delays or cancellations, including from the potential adverse effects of the COVID-19 pandemic on economic activity, and/or other project-related factors. These changes could cause estimated revenue to be realized in periods later than originally expected, or not at all. We occasionally experience postponements, cancellations and reductions in expected future work from master service agreements and/or construction projects due to changes in our customers’ spending plans, market volatility, ~~and~~ regulatory delays and/or other factors. There can be no assurance as to our customers’ requirements or if actual results will be consistent with the ~~accuracy of~~estimates included in our ~~estimates.~~forecasts. As a result, our backlog as of any particular date is an uncertain indicator of future revenue and earnings.

Backlog is a common measurement used in our industry. Our methodology for determining backlog may not, however, be comparable to the methodologies used by others. Backlog differs from the amount of our remaining performance obligations, which are described in Note 1 - Business, Basis of Presentation and Significant Accounting Policies in the notes to the consolidated financial statements, which is incorporated by reference. As of ~~March 31,~~September 30, 2020, total 18-month backlog differed from the amount of our remaining performance obligations due primarily to the inclusion of ~~$3.4~~$3.3 billion of estimated future revenue under master service and other service agreements within our backlog estimates, as described above, and the exclusion of approximately ~~$0.8~~$0.9 billion of remaining performance obligations and estimated future revenue under master service and other service agreements in excess of 18 months, which amount is not included in the backlog estimates above. Backlog expected to be realized in 2020 differed from the amount of remaining performance obligations expected to be recognized for the same period due primarily to the inclusion of approximately ~~$1.1~~$0.3 billion of estimated future revenue under master service and other service agreements that is included within the related backlog estimate.

Economic, Industry and Market Factors

In addition to the effects of the pandemic noted above, we closely monitor the effects of changes in economic and market conditions on our customers. General economic and market conditions can negatively affect demand for our customers’ products and services, which can affect our customers’ planned capital and maintenance budgets in certain end-markets. Market, regulatory and industry factors could affect demand for our services, including (i) changes to our customers’ capital spending plans, including any potential effects from public health issues, such as the recent COVID-19 pandemic; (ii) economic, political or other market developments, including access to capital for customers in the industries we serve; (iii) new or changing regulatory requirements or other governmental policy changes or political developments or uncertainty; (iv) changes in technology, tax and other incentives; and (v) mergers and acquisitions among the customers we serve. Fluctuations in market prices for oil, gas and other fuel sources and availability of transportation and transmission capacity can also affect demand for our services, in particular, on pipeline and ~~power~~energy generation construction projects. These fluctuations, as well as the highly competitive nature of our industry, can result in lower levels of activity and profit on the services we provide. In the face of increased pricing pressure or other market developments, we strive to maintain our profit margins through productivity improvements, cost reduction programs and/or business streamlining efforts. While we actively monitor economic, industry and market factors that could affect our business, we cannot predict the effect that changes in such factors may have on our future results of operations, liquidity and cash flows, and we may be unable to fully mitigate, or benefit from, such changes.

Effect of Seasonality and Cyclical Nature of Business

Our revenue and results of operations can be subject to seasonal and other variations. These variations are influenced by weather, customer

spending patterns, bidding seasons, project schedules, public health matters, holidays and/or timing, in particular, for large non-recurring projects. Typically, our revenue is lowest at the beginning of the year and during the winter months because cold, snowy or wet conditions cause project delays. Revenue is generally higher during the summer and fall months due to increased demand for our services when favorable weather conditions exist in many of the regions in which we operate, but continued cold and wet weather can often affect second quarter productivity. In the fourth quarter, many projects tend to be completed by customers seeking to spend their capital budgets before the end of the year, which generally has a positive effect on our revenue. However, the holiday season and inclement weather can cause delays, which can reduce revenue and increase costs on affected projects. Any quarter may be positively or negatively affected by adverse or unusual weather patterns, including warm winter weather, excessive rainfall, flooding or natural catastrophes such as hurricanes or other severe weather, making it difficult to predict quarterly revenue and margin variations.

Additionally, our industry can be highly cyclical. Fluctuations in end-user demand within the industries we serve, or in the supply of services within those industries, can affect demand for our services. As a result, our business may be adversely affected by industry declines or by delays in new projects. Variations in project schedules or unanticipated changes in project schedules, in particular, in connection with large construction and installation projects, can create fluctuations in revenue, which may adversely affect us in a given quarter, even if not for the full year. In addition, revenue from master service and other service agreements, while generally predictable, can be subject to volatility. The financial condition of our customers and their access to capital; variations in project margins; regional, national and global economic, political and market conditions; regulatory or environmental influences; and acquisitions, dispositions or strategic investments/other arrangements can also materially affect quarterly results in a given period. Accordingly, our operating results in any particular period may not be indicative of the results that can be expected for any other period. The effects of the COVID-19 pandemic could also result in greater seasonal and cyclical volatility than would otherwise exist under normal conditions.

Critical Accounting Estimates

This discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of our consolidated financial statements requires the use of estimates and assumptions that affect the amounts reported in our consolidated financial statements and the accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, including the ~~results~~potential future effects of ~~which~~the COVID-19 pandemic and other relevant global events. These estimates form the basis offor making judgments about our operating results, including the results of construction contracts accounted for under the cost-to-cost method, and the carrying values of assets and liabilities, that are not readily apparent from other sources. Given that management estimates, by their nature, involve judgments regarding future uncertainties, actual results may differ from these estimates if conditions change or if certain key assumptions used in making these estimates ultimately prove to be inaccurate. Our accounting policies and critical accounting estimates are reviewed periodically by the Audit Committee of the Board of Directors. During the first quarter of 2020, we performed quantitative assessments of the goodwill associated with certain of our reporting units and of two indefinite-lived pre-qualification intangible assets in conjunction with our quarterly review for indicators of impairment. Based on the results of these assessments, we determined that the estimated fair value of one of the reporting units in our Oil and Gas segment, for which the related goodwill has a carrying value of approximately $14 million, exceeded its carrying value by approximately 10%, and that the fair value of a separate reporting unit, for which the related goodwill has a carrying value of approximately $15 million, exceeded its carrying value by approximately 10%. In addition, we reassessed the indefinite life classification of a pre-qualification intangible asset within our Oil and Gas operating segment and a pre-qualification intangible asset within our Electrical Transmission segment with a combined carrying value of $70 million, and determined that based on changes in the assets’ characteristics, including current and expected changes in the customer mix of the associated reporting units, a finite life classification for these assets was more appropriate. As a result, we changed the classification of these pre-qualification intangible assets from indefinite-lived to finite-lived, and began amortizing them on an accelerated basis, with an estimated remaining weighted average useful life of approximately 12 years as of March 31, 2020.

Significant changes in the assumptions or estimates used in management’s assessment, such as a reduction in profitability and/or cash flows, could result in non-cash goodwill and indefinite-lived intangible asset impairment charges in the future.

We believe that our accounting estimates pertaining to: the recognition of revenue and project profit or loss, which we define as project revenue, less project costs of revenue, including project-related depreciation, in particular, on construction contracts accounted for under the cost-to-cost method, for which the recorded amounts require estimates of costs to complete and the amount and probability of variable consideration included in the contract transaction price; fair value estimates, including those related to acquisitions, valuations of goodwill, indefinite-lived intangible assets and acquisition-related contingent consideration; income taxes; self-insurance liabilities; and litigation and other contingencies, are

the most critical in the preparation of our consolidated financial statements as they are important to the portrayal of our financial condition and require significant or complex judgment and estimates on the part of management. Actual results could, however, vary materially from these accounting estimates.

Acquisitions contributed $4 million of general and administrative expenses for the three month period ended ~~March 31,~~September 30, 2020. Excluding the

effects of acquisitions, general and administrative expenses for the three month period ended ~~March 31,~~September 30, 2020 ~~included an increase~~decreased by $8 million, primarily due to reductions in ~~various administrative costs, including incentive~~compensation, travel and ~~compensation and information technology expenses, as well as~~professional fee expense, offset, in part, by the ~~effect of timing~~effects of legal and settlement ~~matters~~matter timing and provisions for potential credit losses as compared with the same period in the prior year. Overall, general and administrative expenses as a percentage of revenue increased by approximately ~~130~~50 basis points for the three month period ended ~~March 31,~~September 30, 2020 as compared with the same period in 2019, primarily due ~~in part,~~ to lower levels of revenue.

Interest expense, net. Interest expense, net of interest income, was ~~$17~~$14 million, or approximately ~~1.2%~~0.8% of revenue, for the three month period ended ~~March 31,~~September 30, 2020 as compared with ~~$22~~$19 million, or ~~1.5%~~1.0% of revenue, for the same period in 2019. The decrease in interest expense, net, related primarily to a reduction in interest expense from credit facility activity as well as a decrease in discount charges on financing arrangements for trade receivables. Interest expense from credit facility activity decreased by approximately $5 million as compared with the same period in the prior year due to a combination of lower average balances and ~~a decrease~~lower interest rates. The reduction in interest ~~rates.~~expense on credit facility activity was offset, in part, by an increase in interest expense on senior notes.

Loss on extinguishment of debt. We incurred a debt extinguishment loss of approximately $6 million for the three month period ended September 30, 2020 in connection with the repurchase and redemption of our 4.875% Senior Notes, composed of approximately $3 million of early repayment premiums and $2 million from the write-off of unamortized deferred financing costs.

Other (income) expense, net. Other (income) expense, net, consists primarily of gains or losses from sales of, or changes in estimated recoveries from, assets and investments, certain legal/other settlements and gains or losses from changes to estimated earn-out accruals. Other income, net, was $1$7 million for the three month period ended ~~March 31,~~September 30, 2020, as compared with ~~approximately $4~~$8 million of other expense, net, for the same period in 2019.

The decrease in organic revenue was primarily driven by a decrease in install-to-the-home revenue and wireless revenue, including from the effects of the COVID-19 pandemic, offset, in part, by higher levels of wireline/fiber revenue.

Oil and Gas Segment. Oil and Gas revenue was $1,190 million for the nine month period ended September 30, 2020, as compared with $2,531 million for the same period in 2019, a decrease of $1,340 million, or 53%. The expected decrease was primarily due to lower levels of project activity and mix, including the effects of regulatory disruptions on certain pipeline construction activity.

Electrical Transmission Segment. Electrical Transmission revenue was $381 million for the nine month period ended September 30, 2020 as compared with $298 million for the same period in 2019, an increase of approximately $82 million, or 28%, due primarily to higher levels of project activity and timing.

Clean Energy and Infrastructure Segment. Clean Energy and Infrastructure revenue was $1,181 million for the nine month period ended September 30, 2020 as compared with $701 million for the same period in 2019, an increase of $480 million, or 68%. Organic revenue increased by approximately $416 million, or 59%, as compared with the same period in 2019, and acquisitions contributed $64 million of revenue for the nine month period ended September 30, 2020. The increase in organic revenue was driven by higher levels of renewable power project activity.

Costs of revenue, excluding depreciation and amortization. Costs of revenue, excluding depreciation and amortization, decreased by $687 million, or 15%, to $3,949 million for the nine month period ended September 30, 2020 from $4,636 million for the same period in 2019. Lower levels of revenue contributed a decrease in costs of revenue, excluding depreciation and amortization, of $669 million, and improved productivity contributed a decrease of approximately $18 million. Costs of revenue, excluding depreciation and amortization, as a percentage of revenue decreased by approximately 40 basis points, from 84.7% of revenue for the nine month period ended September 30, 2019 to 84.3% of revenue for the same period in 2020. The basis point decrease was primarily due to project efficiencies, close-outs and mix across multiple segments, offset, in part, by the impact of the COVID-19 pandemic and lower levels of revenue.

Depreciation. Depreciation was $182 million, or 3.9% of revenue, for the nine month period ended September 30, 2020 as compared with $160 million, or 2.9% of revenue, in 2019, an increase of $22 million, or 14%. Acquisitions contributed $6 million of depreciation for the nine month period ended September 30, 2020 and organic depreciation increased by $16 million due to capital spending in support of expected future levels of activity. As a percentage of revenue, depreciation increased by approximately 100 basis points, due, in part, to lower levels of revenue.

Amortization of intangible assets. Amortization of intangible assets was $28 million, or 0.6% of revenue, for the nine month period ended September 30, 2020, as compared with $14 million, or 0.3% of revenue, for the same period in 2019, an increase of approximately $14 million, or 101%. Acquisitions contributed $10 million of intangible asset amortization for the nine month period ended September 30, 2020. As a percentage of revenue, amortization of intangible assets increased by approximately 30 basis points due primarily to lower levels of revenue, as well as the effects of acquisitions and a change in amortization policy for certain intangible assets.

General and administrative expenses. General and administrative expenses were $243 million, or 5.2% of revenue, for the nine month period ended September 30, 2020, as compared with $221 million, or 4.0% of revenue, for the same period in 2019, an increase of $23 million, or 10%. Acquisitions contributed $13 million of general and administrative expenses for the nine month period ended September 30, 2020. Excluding the effects of acquisitions, administrative expenses increased by approximately $10 million as compared with the same period in the prior year, primarily due to the effect of timing of legal, arbitral and settlement matters and provisions for potential credit losses, offset, in part, by reductions in compensation, travel and professional fees expense. Overall, general and administrative expenses as a percentage of revenue increased by approximately 120 basis points for the nine month period ended September 30, 2020 as compared with the same period in 2019, due, in part, to lower levels of revenue.

Interest expense, net. Interest expense, net of interest income, was $45 million, or 1.0% of revenue, for the nine month period ended September 30, 2020 as compared with $58 million, or 1.1% of revenue, in the same period in 2019. The decrease in interest expense, net, related primarily to a reduction in interest expense from credit facility activity as well as a decrease in discount charges on financing arrangements for trade receivables, offset, in part, by the effect of a second quarter 2019 arbitration award, under which we recovered $5 million of interest costs. Interest expense from credit facility activity decreased by approximately $17 million as compared with the same period in the prior year due to a combination of lower average balances and lower interest rates. The reduction in interest expense on credit facility activity was offset, in part, by an increase in interest expense on senior notes. In August 2020, we issued $600 million aggregate principal amount of 4.50% Senior Notes and redeemed $400 million aggregate principal amount of our 4.875% Senior Notes.

Equity in earnings of unconsolidated affiliates. For the nine month periods ended September 30, 2020, equity in earnings from unconsolidated affiliates totaled approximately $22 million, as compared with $20 million for the same period in 2019, and related primarily to our investments in the Waha JVs, and to a lesser extent, to investments in certain telecommunications entities.

Loss on extinguishment of debt. We incurred a loss on debt extinguishment of approximately $6 million for the nine month period ended September 30, 2020 in connection with the third quarter 2020 repurchase and redemption of our 4.875% Senior Notes, composed of approximately $3 million of early repayment premiums and $2 million from the write-off of unamortized deferred financing costs.

Other (income) expense, net. Other income, net, was $18 million for the nine month period ended September 30, 2020, as compared with other expense, net, of $16 million for the same period in 2019. For the nine month period ended September 30, 2020, other income, net, included approximately $12 million of gains on sales of equipment, net, and $6 million, net, of income from certain investments and strategic arrangements, partially offset by approximately $2 million of expense from changes to estimated earn-out accruals, net. For the nine month period ended September 30, 2019, other expense, net, included $48 million of expense from changes to estimated earn-out accruals, net, offset, in part, by $19 million of other income from a second quarter 2019 arbitration award, $10 million of gains on sales of equipment, net, and $2 million of income from the settlement of an investment and gains on sales of other assets.

Provision for income taxes. Income tax expense was $62 million for the nine month period ended September 30, 2020, as compared with income tax expense of $95 million for the same period in 2019. Pre-tax income decreased to $271 million for the nine month period ended September 30, 2020, as compared with $388 million for the same period in the prior year. ~~Our~~For the nine month period ended September 30, 2020, our effective tax rate decreased to ~~1.2% for the three month period ended March 31, 2020~~22.7% from ~~21.8%~~24.5% for the same period in 2019.

Foreign Operations

Our foreign operations are primarily in Canada and, to a lesser extent, in Mexico and the Caribbean. See Note 13 - Segments and Related Information in the notes to the consolidated financial statements, which is incorporated by reference.

Non-U.S. GAAP Financial Measures

As appropriate, we supplement our reported U.S. GAAP financial information with certain non-U.S. GAAP financial measures, including earnings before interest, income taxes, depreciation and amortization (“EBITDA”), adjusted EBITDA (“Adjusted EBITDA”), adjusted net income (“Adjusted Net Income”) and adjusted diluted earnings per share (“Adjusted Diluted Earnings Per Share”). These “adjusted” non-U.S. GAAP measures exclude, as applicable to the particular periods, non-cash stock-based compensation expense; amortization of intangible assets; the loss on debt extinguishment from the redemption of our 4.875% Senior Notes; and, for Adjusted Net Income and Adjusted Diluted Earnings Per Share, the tax effects of the adjusted items, including non-cash stock-based compensation expense and the effects of changes in statutory tax rates. These definitions of EBITDA and Adjusted EBITDA are not the same as in our Credit Facility or in the indenture governing our senior notes; therefore, EBITDA and Adjusted EBITDA as presented in this discussion should not be used for purposes of determining our compliance with the covenants contained in our debt instruments.

We use EBITDA and Adjusted EBITDA, as well as Adjusted Net Income and Adjusted Diluted Earnings Per Share to evaluate our performance, both internally and as compared with our peers, because these measures exclude certain items that may not be indicative of our core operating results, as well as items that can vary widely across different industries or among companies within the same industry. Non-cash stock-based compensation expense can be subject to volatility from changes in the market price per share of our common stock or variations in the value and number of shares granted, and amortization of intangible assets is subject to acquisition activity, which varies from period to period. We believe that these adjusted measures provide a baseline for analyzing trends in our underlying business.

We believe that these non-U.S. GAAP financial measures provide meaningful information and help investors understand our financial results and assess our prospects for future performance. Because non-U.S. GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies’ non-U.S. GAAP financial measures having the same or similar names. These financial measures should not be considered in isolation from, as substitutes for, or alternative measures of, reported net income or diluted earnings per share, and should be viewed in conjunction with the most comparable U.S. GAAP financial measures and the provided reconciliations thereto. We believe these non-U.S. GAAP financial measures, when viewed together with our U.S. GAAP results and related reconciliations, provide a more complete understanding of our business. We strongly encourage investors to review our consolidated financial statements and publicly filed reports in their entirety and not rely on any single financial measure.

The following table presents a reconciliation of net income to EBITDA and Adjusted EBITDA in dollar and percentage of revenue terms, for the periods indicated. The tables below (dollar amounts in millions) may contain slight summation differences due to rounding.

Tax effects are determined based on the tax treatment of the related item, the incremental statutory tax rate of the jurisdictions pertaining to the adjustment, and their effect on pre-tax income. For the three and nine month periods ended September 30, 2020, our consolidated effective tax rates, as reported, were 25.7% and 22.7%, respectively, and as adjusted, were 25.2% and 22.6%, respectively. For the three and nine month periods ended September 30, 2019, our consolidated effective tax rates, as reported, were 25.0% and 24.5%, respectively, and as adjusted, were 25.0% and 25.4%, respectively.

(b) The nine month period ended September 30, 2019 includes the effects of changes in Canadian provincial statutory tax rates as well as changes in statutory rates.

Financial Condition, Liquidity and Capital Resources

Our primary sources of liquidity are cash flows from operations, availability under our Credit Facility and our cash balances. Our primary liquidity needs are for working capital, capital expenditures, insurance and performance collateral in the form of cash and letters of credit, earn-out obligations, equity investment funding requirements, debt service and income taxes. We also evaluate opportunities for strategic acquisitions, investments and ~~investments~~other arrangements from time to time, and we may consider opportunities to borrow additional funds, which may include borrowings under our Credit Facility or debt issuances, or to refinance or retire outstanding debt, or repurchase additional shares of our outstanding common stock in the future under share repurchase authorizations, ~~or to repurchase, refinance or retire outstanding debt,~~ any of which may require our use of cash. See Note 7 - Debt in the notes to the consolidated financial statements in this Form 10-Q, which is incorporated by reference, for details of our $600 million Private Offering of 4.50% Senior Notes and the redemption of our 4.875% Senior Notes during the third quarter of 2020.

Capital Expenditures. For the ~~three~~nine month period ended ~~March 31,~~September 30, 2020, we spent ~~$61~~$184 million on capital expenditures, or ~~$52~~$154 million, net of asset disposals, and incurred approximately ~~$27~~$86 million of equipment purchases under finance leases. We estimate that we will spend approximately ~~$180~~$230 million on capital expenditures, or approximately ~~$150~~$190 million, net of asset disposals, in 2020, and expect to incur approximately ~~$140~~$130 million to ~~$160~~$150 million of equipment purchases under finance leases. Actual capital expenditures may increase or decrease in the future depending upon business activity levels, as well as ongoing assessments of equipment lease versus buy decisions based on short and long-term equipment requirements.

Acquisitions and Earn-Out Liabilities. We typically utilize cash for business acquisitions and other strategic ~~arrangements.~~arrangements, and for the nine month period ended September 30, 2020, we used $11 million of cash for this purpose. In addition, in most of our acquisitions, we have agreed to make future payments to the sellers that are contingent upon the future earnings performance of the acquired businesses, which we also refer to as “earn-out” payments. Earn-out payments may be paid in cash or, under specific circumstances, MasTec common stock, or a combination thereof, at our option. The estimated total value of future acquisition-related contingent consideration and other liabilities as of ~~March 31,~~September 30, 2020 was approximately ~~$176~~$133 million. Of this amount, ~~$60~~$34 million represents the liability for earned amounts. The remainder is management’s estimate of acquisition-related contingent consideration and other liabilities that are contingent upon future performance. For the ~~three~~nine month periods ended ~~March 31,~~September 30, 2020 and 2019, we made nopayments of $50 million and $30 million, respectively, related to earn-out ~~payments.~~obligations.

Income Taxes. For the ~~three~~nine month period ended ~~March 31,~~September 30, 2020, tax ~~refunds,~~payments, net of tax ~~payments~~refunds were ~~de minimis, whereas for~~$12 million. For the ~~three~~nine month period ended ~~March 31,~~September 30, 2019, tax payments, net of tax refunds, totaled approximately $3$74 million. Our tax payments vary with changes in taxable income and earnings based on estimates of full year taxable income activity and estimated tax rates.

Working Capital. We need working capital to support seasonal variations in our business, primarily due to the effect of weather conditions on external construction and maintenance work and the spending patterns of our customers, both of which influence the timing of associated spending to support related customer demand. Working capital needs are generally higher during the summer and fall months due to increased demand for our services when favorable weather conditions exist in many of the regions in which we operate. Conversely, working capital needs are typically converted to cash during the winter months. These seasonal trends, however, can be offset by changes in the timing of projects, which can be affected by project delays or accelerations and/or other factors that may affect customer spending.

Working capital requirements also tend to increase when we commence multiple projects or particularly large projects because labor, including subcontractor costs, and certain other costs, including inventory, become payable before the receivables resulting from work performed are collected. The timing of billings and project close-outs can contribute to changes in unbilled revenue. As of ~~March 31,~~September 30, 2020, we expect that substantially all of our unbilled receivables will be billed to customers in the normal course of business within the next twelve months. Total

accounts receivable, which consists of contract billings, unbilled receivables and retainage, net of allowance, ~~decreased to $1.8 billion as of March 31, 2020 from~~were generally flat at approximately $1.9 billion ~~as of~~for both September 30, 2020 and December 31, ~~2019, due primarily to lower levels of quarterly revenue, offset, in part, by higher DSOs, as described further below.~~2019.

Our payment billing terms are generally net 30 days, and some of our contracts allow our customers to retain a portion of the contract amount (generally, from 5% to 10% of billings) until the job is completed. As part of our ongoing working capital management practices, we evaluate opportunities to improve our working capital cycle time through contractual provisions and certain financing arrangements. For certain customers, we maintain inventory to meet the materials requirements of the contracts. Occasionally, certain of our customers pay us in advance for a portion of the materials we purchase for their projects or allow us to pre-bill them for materials purchases up to specified amounts. Vendor terms are generally 30 days. Our agreements with subcontractors often contain a “pay-if-paid” provision, whereby our payments to subcontractors are made only after we are paid by our customers.

Summary of Financial Condition, Liquidity and Capital Resources

Including our current assessment of the potential effects of the COVID-19 pandemic on our results of operations and capital resource requirements, we anticipate that funds generated from operations, borrowings under our Credit Facility and our cash balances will be sufficient to meet our working capital requirements, anticipated capital expenditures, debt service obligations, insurance and performance collateral requirements, letter of credit needs, earn-out obligations, required income tax payments, acquisition and other investment funding requirements, share repurchase activity and other liquidity needs for at least the next twelve months.

Sources and Uses of Cash

As of ~~March 31,~~September 30, 2020, we had approximately $820 million in working capital, defined as current assets less current liabilities, as compared with $954 million as of December 31, 2019, a decrease of approximately $135 million. Cash and cash equivalents totaled approximately ~~$72 million and $71~~$238 million as of ~~March 31,~~September 30, 2020, and included net proceeds from the third quarter issuance of our 4.50% Senior Notes, net of the redemption of our 4.875% Senior Notes, as described in further detail below. As of December 31, 2019, ~~respectively.~~cash and equivalents totaled $71 million.

Sources and uses of cash are summarized below (in millions):

Operating Activities. Cash flow from operations is primarily influenced by changes in the timing of demand for our services and operating margins, but iscan also be affected by working capital needs associated with the various types of services we provide. Working capital is affected by changes in total accounts receivable, prepaid expenses and other current assets, accounts payable and payroll tax payments, including the effect of deferrals from COVID-19 relief provisions, accrued expenses and ~~deferred revenue,~~contract liabilities, all of which tend to be related. These working capital items are affected by changes in revenue resulting from the timing and volume of work performed, variability in the timing of customer billings and collections of receivables, as well as settlement of payables and other obligations. Net cash provided by operating activities for the ~~three~~nine month period ended ~~March 31,~~September 30, 2020 was ~~$203~~$712 million, as compared with ~~$47~~approximately $441 million ~~of net cash used in operating activities~~ for the same period in 2019, for an increase in cash provided by operating activities of approximately ~~$250~~$271 million. The increase in cash flow from operating activities was primarily due to the effect of working capital-related changes in assets and liabilities, ~~net.~~net, offset, in part, by a reduction in net income.

Our days sales outstanding, net of ~~deferred revenue~~contract liabilities (“DSO”) was ~~104~~85 as of ~~March 31,~~September 30, 2020 and 9190 as of December 31, 2019. The increase in DSO for the three month period ended March 31, 2020 was primarily due to timing of project activity and mix, as well as delays in ordinary course quarter-end collections as a result of administrative and operational disruptions to our customers resulting from voluntary and government-mandated responses to the COVID-19 pandemic. DSO is calculated as total accounts receivable, net of allowance, less ~~deferred revenue,~~contract liabilities, divided by average daily revenue for the most recently completed quarter as of the balance sheet date. DSOs can fluctuate from period to period due to timing of billings, billing terms, collections and settlements, timing of project close-outs and retainage collections, changes in project and customer mix and the effect of working capital initiatives. The decrease in our DSOs for the nine month period ended September 30, 2020 was due to timing of ordinary course billing and collection activities. Other than matters subject to litigation, we do not anticipate material collection issues related to our outstanding accounts receivable balances, nor do we believe that we have material amounts due from customers experiencing financial difficulties. Based on current expectations, we expect to collect substantially all of our outstanding accounts receivable balances within the next twelve months.

Investing Activities. Net cash used in investing activities ~~decreased~~increased by ~~$52~~approximately $34 million to ~~$59~~$177 million for the ~~three~~nine month period ended ~~March 31,~~

September 30, 2020 from ~~$111~~$144 million for the ~~three~~nine month period ended ~~March 31,~~September 30, 2019. ~~Cash paid for acquisitions, net, decreased by approximately $94 million.~~ For the ~~three~~nine month period ended ~~March 31,~~September 30, 2020, we spent ~~$61~~$184 million on capital expenditures, or ~~$52~~$154 million, net of asset disposals, as compared with ~~$34~~$85 million, or ~~$26~~$58 million, net of asset disposals, for the same period in the prior year, for an increase in cash used in investing activities of ~~$26~~$96 million. ~~For~~Cash paid for acquisitions, net, decreased by approximately $83 million for the ~~three~~nine month period ended ~~March 31,~~September 30, 2020 ~~payments~~as compared with the same period in the prior year. Payments for other investments totaled ~~$12~~$17 million for the nine month period ended September 30, 2020 and related primarily to certain equity and other investments, ~~in certain telecommunications entities,~~ whereas for the ~~three~~nine month period ended ~~March 31,~~September 30, 2019, payments for other investments totaled $2$6 million, for an increase of ~~$10~~approximately $12 million in cash used in investing activities. ~~For~~Proceeds from other investments for the ~~three~~nine month period ended ~~March 31,~~September 30, 2020 decreased by $14 million as compared with the same period in the prior year, which included the sale of an investment in a telecommunications entity and ~~2019, proceeds from other investments and other investing activities totaled $5 million and $10 million, respectively.~~the settlement of a separate investment.

Financing Activities. Net cash used in financing activities for the ~~three~~nine month period ended ~~March 31,~~September 30, 2020 was ~~$145~~$369 million, as compared with net cash ~~provided by~~used in financing activities of ~~$174~~$282 million for the ~~three~~nine month period ended ~~March 31,~~September 30, 2019, for an increase in cash used in financing activities of ~~$319~~$87 million. The increase in cash used in financing activities was driven primarily by Credit facility-related activity and

share repurchases, offset in part, by proceeds from the issuance of $600 million aggregate principal amount of our 4.50% Senior Notes in the third quarter of 2020, net of the redemption of $400 million aggregate principal amount of our 4.875% Senior Notes. Credit facility and other borrowing-related activity, net, for the ~~three~~nine month period ended ~~March 31,~~September 30, 2020 totaled $4$310 million of ~~borrowings,~~repayments, net of ~~repayments,~~borrowings, as compared with ~~$196~~$187 million for the ~~three~~nine month period ended ~~March 31,~~September 30, 2019, for a decrease in cash provided by financing activities of approximately $191 million. Additionally, for the three month period ended March 31, 2020, payments for repurchases of common stock totaled $119 million, whereas for the three month period ended March 31, 2019, share repurchases totaled $6 million, for an increase in cash used in financing activities of approximately ~~$114~~$124 million. Additionally, payments of finance lease obligations increased by $33 million for the nine month period ended September 30, 2020. Payments for repurchases of common stock totaled $120 million for the nine month period ended September 30, 2020, an increase of approximately $115 million as compared with the same period in the prior year. Payments of acquisition-related contingent consideration included within financing activities totaled $39 million for the nine month period ended September 30, 2020 as compared with $29 million for the same period in the prior year, for an increase of $10 million in cash used in financing activities. Total payments of acquisition-related contingent consideration, including payments in excess of acquisition-date liabilities, which are classified within operating activities, totaled $50 million and $30 million for the nine month periods ended September 30, 2020 and 2019, respectively. Payments for other financing activities, which relate to payments of financing costs for debt instruments, including early repayment premiums on the redemption of our 4.50% Senior Notes, totaled $11 million for the nine month period ended September 30, 2020, an increase of $6 million as compared with the same period in the prior year.

Senior Secured Credit Facility

We have a senior secured credit facility ~~which was amended and restated in September 2019~~ (the “Credit Facility”). maturing on September 19, 2024. Aggregate borrowing commitments under the Credit Facility total $1.75 billion, composed of $1.35 billion of revolving commitments and a term loan totaling $400 million in original principal amount. Borrowings under the Credit Facility are used for working capital requirements, capital expenditures and other corporate purposes, including share repurchases, equity investments, potential acquisitions or other strategic arrangements and the repurchase or prepayment of indebtedness.

We are dependent upon borrowings and letters of credit under the Credit Facility to fund our operations. Should we be unable to comply with the terms and conditions of ~~the~~our Credit Facility, we would be required to obtain modifications to the Credit Facility or obtain an alternative source of financing to continue to operate, neither of which may be available to us on commercially reasonable terms, or at all. The Credit Facility is subject to certain provisions and covenants, as more fully described in Note 7 - Debt in the notes to the audited consolidated financial statements included in our 2019 Form 10-K.

Issuance of 4.50% Senior Notes and Repurchase and Redemption of 4.875% Senior Notes

~~We have~~In August 2020, we issued $600 million aggregate principal amount of 4.50% Senior Notes due August 15, 2028 in a private offering and used a portion of the net proceeds to repurchase and redeem $400 million aggregate principal amount of ~~4.875% senior notes due March 15, 2023 (our “4.875% Senior Notes”) outstanding. The~~our 4.875% Senior Notes. The remaining net proceeds from the 4.50% Senior Notes ~~are guaranteed by certain of~~offering were primarily used to repay revolving loans under our ~~subsidiaries and are subject to certain provisions and covenants, as more fully described in~~Credit Facility. See Note 7 - Debt and Note 17 - Supplemental Guarantor Condensed Consolidating Financial Information in the notes to the audited consolidated financial statements included in our 2019 Form 10-K. Also, see Note 16 - Supplemental Guarantor Condensed Consolidating Financial Information in the notes to the consolidated financial statements, ~~in this Form 10-Q,~~ which is incorporated by reference.

We were in compliance with the provisions and covenants contained in our outstanding debt instruments as of ~~March 31,~~September 30, 2020.

Additional Information

For detailed discussion and additional information pertaining to our debt instruments, see Note 7 - Debt in the notes to the audited consolidated financial statements included in our 2019 Form 10-K. Also see Note 7 - Debt in the notes to the consolidated financial statements in this Form 10-Q for current period balances and discussion, which is incorporated by reference.

Off-Balance Sheet Arrangements

As is common in our industry, we have entered into certain off-balance sheet arrangements in the ordinary course of business. Our significant off-balance sheet transactions include liabilities associated with non-cancelable operating leases with durations of less than twelve months, letter of credit obligations, surety and performance and payment bonds entered into in the normal course of business, self-insurance liabilities, liabilities associated with multiemployer pension plans, liabilities associated with certain indemnification and guarantee arrangements and obligations relating to our equity and other investment arrangements, including our variable interest entities. Refer to Note 14 - Commitments and Contingencies, Note 4 - Fair Value of Financial Instruments and Note 15 - Related Party Transactions in the notes to the consolidated financial statements, which are incorporated by reference.

The primary inflationary factors affecting our operations are labor and fuel costs, and to a lesser extent, material costs. In times of low unemployment, our labor costs may increase due to shortages in the supply of skilled labor. Additionally, the prices of oil and gas are subject to unexpected fluctuations due to events outside of our control, including geopolitical events and fluctuations in global supply and demand. We closely monitor inflationary factors and any impact they may have on our operating results or financial condition.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As of ~~March 31,~~September 30, 2020, our variable interest rate debt was primarily related to our Credit Facility. Interest on outstanding revolving loans and our term loan under our Credit Facility accrues at variable rates based, at our option, on a Eurocurrency rate, as defined in the Credit Facility, plus a margin, or a base rate, as defined in the Credit Facility, plus a margin. As of ~~March 31,~~September 30, 2020, we had ~~$333~~$20 million aggregate principal amount of

outstanding revolving loans under our Credit Facility with a weighted average interest rate of ~~2.47%~~1.98% and a term loan with a

balance of $400 million with an interest rate of ~~2.24%~~1.39%. A 100 basis point increase in the applicable interest rates under our credit facilities would have increased our interest expense by approximately $2$5 million for the ~~three~~nine month period ended ~~March 31,~~September 30, 2020.

As of ~~March 31,~~September 30, 2020, our fixed interest rate debt primarily included ~~$400~~$600 million aggregate principal amount of ~~4.875%~~4.50% Senior Notes and ~~$298~~$295 million of finance lease obligations, which accrued interest at a weighted average interest rate of approximately ~~4.1%~~4.0%. None of this debt subjects us to interest rate risk, but we may be subject to changes in interest rates if and when we refinance this debt at maturity or otherwise.

Foreign Currency Risk

Certain of our consolidated revenue and operating expenses are in foreign currencies. Our foreign operations are primarily in Canada. Revenue generated from foreign operations represented 3%2% of our total revenue for the ~~three~~nine month period ended ~~March 31,~~September 30, 2020. Revenue and expense related to our foreign operations are, for the most part, denominated in the functional currency of the foreign operation, which minimizes the impact that fluctuations in exchange rates would have on net income or loss. We are, however, subject to fluctuations in foreign currency exchange rates when transactions are denominated in currencies other than the functional currencies. Such transactions were not material to our operations for the three or nine month ~~period~~periods ended ~~March 31,~~September 30, 2020. Translation gains or losses, which are recorded in other comprehensive income or loss, result from translation of the assets and liabilities of our foreign subsidiaries into U.S. dollars.

Our exposure to fluctuations in foreign currency exchange rates could increase in the future if we continue to expand our operations outside of the United States. We seek to manage foreign currency exposure by minimizing our consolidated net asset and liability positions in currencies other than the functional currency, which exposure was not significant to our consolidated financial position as of ~~March 31,~~September 30, 2020. We may enter into foreign currency derivative contracts in the future to manage such exposure.

As discussed in Note 4 - Fair Value of Financial Instruments in the notes to the consolidated financial statements, which is incorporated by reference, we have certain investments that may be subject to market risk and could be subject to volatility based on market conditions.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based on management’s evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of ~~March 31,~~September 30, 2020.

Changes in Internal Control over Financial Reporting

~~Although the adoption of ASU 2016-13,~~ ~~Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments~~ had no significant effect on our results of operations, cash flows or financial position, certain updates to our internal controls were implemented in connection with its adoption. We have not experienced any material impact to our internal controls over financial reporting due to the COVID-19 pandemic. There have been no changes in the Company’s internal control over financial reporting during the quarter ended ~~March 31,~~September 30, 2020 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION


~~ITEM 1.~~	~~LEGAL PROCEEDINGS~~

ITEM 1. LEGAL PROCEEDINGS

Refer to Note 14 - Commitments and Contingencies in the notes to our consolidated financial statements included in this Quarterly Report on Form 10-Q, which is incorporated by reference in this Item 1, for a discussion of any recent material developments related to our legal proceedings since the filing of our 2019 Form 10-K.

ITEM 1A. RISK FACTORS

Except as set forth below subject to the potential effects of the COVID-19 pandemic on certain of the risks we normally face in operating our business, including those disclosed in our 2019 Form 10-K, there have been no material changes to either the cautionary statement regarding forward-looking statements or to any of the risk factors disclosed in our 2019 Form 10-K, as updated by our Quarterly Report on Form 10-Q and other filings we make with the SEC.

Our business and operations, and the operations of our customers, may be adversely affected by epidemics or pandemics such as the COVID-19 pandemic.

We may face risks related to health epidemics and pandemics or other outbreaks of communicable diseases. The global spread of COVID-19 has created significant volatility, uncertainty and economic disruption, including significant volatility in the U.S. economy and financial markets. The

extent to which the COVID-19 pandemic could affect our business, operations, financial results and the trading price of our common stock will depend on numerous evolving factors that we may not be able to accurately predict, including the duration and scope of the pandemic, governmental and business actions that have been and continue to be taken in response to the pandemic, including mitigation efforts such as ~~stay at home~~"stay-at-home," "shelter-in-place," social distancing, travel restrictions and other ~~social distancing~~similar orders, as well as the impact of the pandemic on the U.S. economy, global economic and market activity and actions taken in response, including from stimulus efforts such as the Families First Coronavirus Act and the ~~Coronavirus Aid, Relief and Economic Security (“CARES”)~~CARES Act.

A public health epidemic or pandemic, such as the COVID-19 pandemic, poses the risk that we or our employees, customers and/or business partners may be prevented from conducting ordinary course business activities for an indefinite period of time, including due to shutdowns or cancellations that may be ~~requested~~mandated or ~~mandated~~requested by governmental authorities or others, or that the pandemic may otherwise interrupt or affect business activities. The ~~effects of the~~COVID-19 pandemic has had a negative effect on our ~~business, operations and financial results for~~operations. While we expect this to continue during the ~~first quarter~~remainder of 2020 ~~were limited.~~ and into early 2021 at least, it is currently unclear how long an economic recovery could take, and we cannot predict the extent or duration of potential negative effects on our operations.We have adjusted standard operating procedures within our business operations to ensure continued employee and customer safety and are continually monitoring evolving health guidelines as well as market conditions and responding to changes as appropriate. We cannot be certain, however, that these efforts will prevent further disruption due to effects of the pandemic on business and market conditions. Additionally, we could be exposed to increased risks and costs associated with workplace health claims. In ~~addition, in~~ light of the federal and state mandates implemented to control the spread of COVID-19, we have taken steps that allow certain administrative personnel to work remotely. Many of these measures are being deployed for the first time and, despite our implementation of information technology security measures, there is no guarantee that the data security and privacy safeguards we have put in place will be completely effective or that we will not encounter some of the common risks associated with employees accessing Company data and systems remotely.

~~If overall~~Disruptions in global economic ~~conditions weaken~~activity as a result of ~~efforts~~the COVID-19 pandemic have had, and may continue to ~~contain the spread of COVID-19, this may result in a reduction in demand~~have, adverse effects across our end markets, ~~including~~particularly in the oil and gas sector, which has ~~recently~~ experienced a significant ~~decline in demand and~~ volatility in oil ~~prices.~~prices and demand. Unfavorable market conditions, market uncertainty and/or economic downturns could continue to have a negative effect on demand for our customers’ services and/or the profitability of services. Our customers may not have the ability to fund capital expenditures for infrastructure, or may have difficulty obtaining financing for planned projects, which could reduce their capital spending and/or result in reduced demand for our services and/or delays or cancellations of current or planned future projects. Delay in the receipt of regulatory approvals due to pandemic-related disruptions could also affect project timing and activity levels. We could also incur incremental costs to operate in the current environment or experience lower levels of overhead absorption from a reduction in revenue, both of which could negatively affect our margins and profitability. Additionally, the economic and market disruptions resulting from COVID-19 could also lead to greater than normal uncertainty with respect to the realization of estimated amounts, including our estimates for backlog, ~~estimates~~revenue recognition, recoverability of goodwill, intangible assets and other investments and our provisions for credit losses. ~~Additionally, our~~Our customers could seek to delay payments to us as a result of the pandemic’s financial effects on ~~them.~~them, which could negatively affect our cash flows and liquidity. The ultimate extent, duration and impact of the COVID-19 pandemic is uncertain, the effects of which could be significant, and we cannot predict or quantify with any certainty the extent to which it could adversely affect our future financial condition, results of operations, liquidity, cash flows or the market price of our common stock.
