NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 – Business, Basis of Presentation and Significant Accounting Policies

Nature of the Business

MasTec, Inc. (collectively with its subsidiaries, “MasTec,” or the “Company”) is a leading infrastructure construction company operating mainly throughout North America across a range of industries. The Company’s 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; power delivery infrastructure, including transmission, distribution, environmental planning and compliance; power generation infrastructure, primarily from clean energy and renewable sources; pipeline infrastructure, including for natural gas, water and carbon capture sequestration pipelines and pipeline integrity services; heavy civil and industrial infrastructure, including roads, bridges and rail; and environmental remediation services. MasTec’s customers are primarily in these industries. MasTec reports its results under five reportable segments: (1) Communications; (2) Clean Energy and Infrastructure; (3) Power Delivery; (4) Oil and Gas; and (5) Other.

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, 2023 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, 2023 contained in the Company’s 2023 Annual Report on Form 10-K (the “2023 Form 10-K”). In management’s opinion, all normal and recurring adjustments considered necessary for a fair statement of the financial position, results of operations and cash flows for the periods presented have been included. 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. Net income or loss attributable to non-controlling interests is reported as a separate line item below net income or loss. Investments in entities for which the Company does not have a controlling financial interest, but over which it has the ability to exert significant influence, are accounted for under 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. For foreign operations for which the local currency is not the functional currency, the operation’s non-monetary assets are remeasured into U.S. dollars at historical exchange rates. All other accounts are remeasured at current exchange rates. Gains or losses from remeasurement are included in other income or expense, net. 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.

Significant Accounting Policies

Revenue Recognition

The Company recognizes revenue from contracts with customers when, or as, control of promised services and goods is transferred to customers. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for the services and goods transferred. The Company primarily recognizes revenue 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 service and other service agreements, which generally 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 may be subject to one or multiple pricing models, 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 40% and 43% of consolidated revenue for the three month periods ended June 30, 2024 and 2023, respectively, and totaled 40% and 45% for the six month periods ended June 30, 2024 and 2023, respectively.

For certain master service and other service agreements, revenue is recognized at a point in time, primarily for install-to-the-home and certain other wireless services in the Company’s Communications segment, and to a lesser extent, certain revenue in the Company’s Clean Energy and Infrastructure and Oil and Gas segments. Point in time revenue is recognized when the work order has been fulfilled, which, for the majority of the Company’s point in time revenue, is the same day it is initiated. Point in time revenue accounted for approximately 2% of consolidated revenue for both the three and six month periods ended June 30, 2024, and totaled approximately 3% for both the three and six month periods ended June 30, 2023.

The total contract transaction price and cost estimation processes used for recognizing revenue over time under the cost-to-cost method is based primarily on the professional knowledge and experience of the Company’s project managers, operational and financial professionals and other professional expertise, as warranted. Management reviews estimates of total contract transaction price and costs on an ongoing basis. Changes in job performance, job conditions and management’s assessment of the estimated amount and probability of 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 the amount of revenue recognized in the period in which the revisions are determined, which revisions 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 based on management’s estimates. For the six month periods ended June 30, 2024 and 2023, 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, 2023 and 2022. Changes in recognized revenue, net, as a result of changes in total contract transaction price estimates, including from variable consideration, and/or changes in cost estimates, related to performance obligations satisfied or partially satisfied in prior periods positively affected revenue by approximately 0.4% and 1.5% for the three month periods ended June 30, 2024 and 2023, respectively, and such net changes positively affected revenue by approximately 0.2% and 0.6% for the six month periods ended June 30, 2024 and 2023, respectively.

Performance Obligations. A performance obligation is a contractual promise to transfer a distinct good or service to a customer. 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 Company’s contracts often require significant services to integrate complex activities and equipment into a single deliverable, and are therefore generally accounted for as a single performance obligation, even when delivering multiple distinct services. The 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 June 30, 2024, the amount of the Company’s remaining performance obligations was $9.3 billion. Based on current expectations, the Company anticipates it will recognize approximately $4.2 billion, or 45.0%, of its remaining performance obligations as revenue during 2024, with the majority of the remaining balance expected to be recognized over the subsequent two year period.

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 specific discussions, correspondence or preliminary negotiations and past practices with the customer, engineering studies and legal advice 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 June 30, 2024 and December 31, 2023, the Company’s contract transaction prices included approximately $175 million and $194 million, respectively, of change orders and/or claims for certain contracts that were in the process of being resolved in the ordinary course of its 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 June 30, 2024 and December 31, 2023, these change orders and/or claims primarily related to certain projects in the Company’s Clean Energy and Infrastructure and Power Delivery segments. The Company actively engages with its customers to complete the final approval process for such amounts 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.

Recent Accounting Pronouncements

The discussion below describes the effects of recent accounting pronouncements, as updated from the discussion in the Company’s 2023 Form 10-K.

In August 2023, the FASB issued ASU 2023-05, Business Combinations—Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement (“ASU 2023-05”) to clarify existing guidance and reduce diversity in practice in the accounting for joint ventures. ASU 2023-05 addresses the accounting for contributions made to a joint venture upon formation in a joint venture’s separate financial statements. The provisions of this ASU require that a joint venture initially measure all contributions received upon its formation at fair value, largely consistent with Topic 805, Business Combinations. The amendments in this ASU are not applicable to the formation of proportionately consolidated joint ventures. ASU 2023-05 is effective prospectively for all joint ventures with a formation date on or after January 1, 2025, with early adoption permitted on a retrospective basis for joint ventures formed before January 1, 2025. The Company is currently evaluating the effects of this ASU.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”) to enhance segment reporting disclosures. ASU 2023-07 requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within each reported measure of segment profit or loss, as well as disclosure of the total amount and description of other segment items by reportable segment. This ASU also requires disclosure of the title and position of the CODM and an explanation of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources. Under ASU 2023-07, the disclosures that are currently required on an annual basis under Topic 280, Segment Reporting,

pertaining to reportable segment profit or loss and assets will also be required for interim periods. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with retrospective application. Early adoption is permitted. The Company is currently evaluating the effect of this ASU on its segment disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”) to enhance transparency and decision usefulness of income tax disclosures. ASU 2023-09 requires greater standardization and disaggregation of categories within an entity’s tax rate reconciliation disclosure, as well as disclosure of income taxes paid by jurisdiction, among other requirements. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, with early adoption permitted. ASU 2023-09 is effective on a prospective basis, with retrospective application permitted. The Company is currently evaluating the effects of this ASU on its income tax disclosures.

In March 2024, the Securities and Exchange Commission (“SEC”) adopted final rules under SEC Release No. 33-11275, The Enhancement and Standardization of Climate-Related Disclosures for Investors, which requires registrants to provide certain climate-related disclosures in registration statements and annual reports. The new rules are scheduled to begin to phase in for fiscal years beginning on or after January 1, 2025, on a prospective basis. On April 4, 2024, the SEC voluntarily stayed implementation of the final rules pending certain legal challenges to the rules. The Company is currently monitoring developments related to the rules and evaluating their potential effect on its consolidated financial statements.

Note 2 – Earnings Per Share

Basic earnings or loss per share is computed by dividing net income or loss 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 primarily under the treasury stock method, which includes the potential effect of dilutive common stock equivalents, such as issued but unvested restricted shares.

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

During the first quarter of 2024, the reporting units within the Power Delivery operating segment were restructured to more closely align with the segment’s end markets and to better correspond with the operational management reporting structure of the segment, including from the effects of the Company’s recent transformative acquisition efforts. Under the new reporting unit structure, each of the five components within the Power Delivery operating segment is a reporting unit. Management performed testing under the previous reporting unit structure and determined that no goodwill impairment existed, and under the new reporting unit structure the estimated fair values of all but one of the reporting units substantially exceeded their carrying values. A 100 basis point increase in the discount rate would not have resulted in any of the tested reporting units’ carrying values exceeding their fair values. As of March 31, 2024, the reporting unit that did not substantially exceed its carrying value had approximately $47.1 million of goodwill. This reporting unit’s estimated fair value exceeded its carrying value by approximately 16%. Significant assumptions used in testing this reporting unit included terminal values based on a terminal growth rate of 3%, 5 years of discounted cash flows prior to the terminal value, including revenue growth and EBITDA margin assumptions, and a weighted average discount rate of 12%.

Additionally, no events occurred during the three month period ended June 30, 2024 that would indicate it was more likely than not that a goodwill impairment exists. Significant changes in the assumptions or estimates used in management’s assessment, such as a reduction in profitability and/or cash flows, changes in market, regulatory or other conditions, including decreases in project activity levels and/or the effects of elevated levels of inflation, market interest rates or other market disruptions, including from geopolitical or other events, could result in non-cash impairment charges to goodwill and indefinite-lived intangible assets in the future.

Recent Acquisitions

The Company seeks to grow and diversify its business both organically and through acquisitions and/or strategic arrangements in order to deepen its market presence and customer base, broaden its geographic reach and expand its service offerings. Acquisitions are funded with cash on hand, borrowings under the Company’s senior unsecured credit facility and other debt financing and, for certain acquisitions, with shares of the Company’s common stock, and are generally subject to customary purchase price adjustments.

2024 Acquisitions. In July 2024, MasTec acquired all of the equity interests of a construction company focused on underground utility infrastructure for industrial and municipal projects, with expertise in data center utility systems, for approximately $35 million in cash and a five year earn-out liability. The Company expects to include the results of operations from the date of acquisition within the Power Delivery segment. The Company is in the process of preparing its initial valuation of the tangible and intangible assets relating to this acquisition and the allocation of the purchase price to the assets acquired and liabilities assumed.

2023 Acquisitions. During 2023, MasTec completed four acquisitions, including the acquisition of certain assets of a telecommunications company specializing in wireless services, which acquisition was included within the Company’s Communications segment, and was effective in January; and, effective in July, the acquisition of the equity interests of a telecommunications construction company specializing in broadband and fiber-to-the-home initiatives in the New England area, which acquisition was included within the Company’s Communications segment. Determination of the estimated fair values of the net assets acquired and consideration transferred for these acquisitions, which have been accounted for as business combinations under ASC Topic 805, Business Combinations (“ASC 805”), was substantially complete as of June 30, 2024, with exception for certain seller tax reimbursements. Additionally, effective in May 2023, MasTec acquired certain of the equity interests of two equipment companies which were accounted for as asset acquisitions under ASC 805 and were included within the Company’s Oil and Gas segment.

The aggregate purchase price of the Company’s 2023 acquisitions was composed of approximately $69 million in cash, net of cash acquired, and an earn-out liability valued at approximately $1 million. As of June 30, 2024, the remaining potential undiscounted earn-out liabilities for the 2023 acquisitions was estimated to be up to $2 million; however, there is no maximum payment amount. See Note 4 – Fair Value of Financial Instruments for fair value estimates and other details related to the Company’s earn-out arrangements. Approximately $42 million of the goodwill balance related to the 2023 acquisitions is expected to be tax deductible as of June 30, 2024.

Acquisition and integration costs. In 2021, the Company initiated a significant transformation of its end-market business operations to focus on the nation’s transition to low-carbon energy sources and position the Company for expected future growth opportunities. This transformation included significant business combination activity, including expansion of the Company’s scale and capacity in renewable energy, power delivery, heavy civil and telecommunications services, which activity resulted in significant acquisition and integration costs in prior periods. These acquisition and integration activities were completed in the fourth quarter of 2023. For the three and six month periods ended June 30, 2023,

such acquisition and integration costs totaled approximately $22.7 million and $39.8 million, respectively, of which $20.4 million and $35.0 million, respectively, was included within general and administrative expenses, and of which $2.3 million and $4.8 million, respectively, was included within costs of revenue, excluding depreciation and amortization.

Note 4 – Fair Value of Financial Instruments

The Company’s financial instruments are primarily composed of cash and cash equivalents, accounts receivable and contract assets, notes receivable, cash collateral deposited with insurance carriers, life insurance assets, equity investments, certain other assets and investments, deferred compensation plan assets and liabilities, accounts payable and other current liabilities, acquisition-related contingent consideration and other liabilities, and debt obligations.

Fair value is the price that would be received to sell an asset or the amount paid to transfer a liability, also referred to as the “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, including quoted market prices for identical or similar assets or liabilities in markets that are not active; 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

Acquisition-related contingent consideration is composed of earn-outs, which represent the estimated fair value of future amounts payable for businesses, which we refer to as “Earn-outs,” that are contingent upon the acquired businesses achieving certain levels of earnings in the future. As of June 30, 2024 and December 31, 2023, the estimated fair value of the Company’s Earn-out liabilities totaled $71.1 million and $77.4 million, respectively. Earn-out liabilities included within other current liabilities totaled approximately $38.5 million and $29.8 million as of June 30, 2024 and December 31, 2023, respectively. 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 was 14.0% as of June 30, 2024, and probability-weighted projections of 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 June 30, 2024, the range of potential undiscounted Earn-out liabilities was estimated to be between $24 million and $82 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. There were no additions from new business combinations or measurement period adjustments in any of the three or six month periods ended June 30, 2024 or 2023. Fair value adjustments totaled an increase, net, of approximately $4.3 million for the three month period ended June 30, 2024 and related primarily to acquisitions within the Company’s Oil and Gas segment, and for the six month period ended June 30, 2024, totaled a decrease, net, of approximately $1.8 million and related primarily to acquisitions within the Company’s Communications and Oil and Gas segments. For the three and six month periods ended June 30, 2023, fair value adjustments totaled a decrease, net, of approximately $1.8 million and $2.1 million, respectively, including decreases related to acquisitions within the Company’s Communications segment, which were largely offset by increases related to acquisitions within the Company’s Clean Energy and Infrastructure and Oil and Gas segments. Earn-out payments totaled approximately $4.6 million for both the three and six month periods ended June 30, 2024, and totaled approximately $24.5 million and $26.1 million for the three and six month periods ended June 30, 2023, respectively.

Equity Investments

The Company’s equity investments as of June 30, 2024 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”); (ii) a 15% equity interest in Cross Country Infrastructure Services, Inc. (“CCI”); (iii) the Company’s 50% equity interests in each of FM Technology Holdings, LLC, FM USA Holdings, LLC and All Communications Solutions Holdings, LLC, collectively “FM Tech”; (iv) the Company’s interests in certain proportionately consolidated non-controlled contractual joint ventures; and (v) certain other equity investments.

As of June 30, 2024 and December 31, 2023, the aggregate carrying value of the Company’s equity investments totaled approximately $328 million and $319 million, respectively. There were no impairments related to these investments in any of the three or six month periods ended June 30, 2024 or 2023.

The Waha JVs. The Waha JVs own and operate certain pipeline infrastructure that transports natural gas to the Mexican border for export. The Company’s investments in the Waha JVs are accounted for as equity method investments. 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 $6.4 million and $14.1 million for the three and six month periods ended June 30, 2024, respectively, and totaled approximately $7.5 million and $15.4 million for the three and six month periods ended June 30, 2023, respectively. Distributions of earnings from the Waha JVs, which are included within operating cash flows, totaled approximately $5.1 million and $9.3 million for the three and six month periods ended June 30, 2024, respectively, and totaled approximately $1.5 million and $5.8 million for the three and six month periods ended June 30, 2023, respectively. Cumulative undistributed earnings from the Waha JVs, which represents cumulative equity in earnings for the Waha JVs less distributions of earnings, totaled $130.4 million as of June 30, 2024. 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 equity method goodwill associated with capitalized investment costs, totaled approximately $282 million and $274 million as of June 30, 2024 and December 31, 2023, respectively.

Other Investments. The Company has equity interests in certain other entities that are accounted for as equity method investments. For both the six month periods ended June 30, 2024 and 2023, the Company made equity contributions of approximately $0.2 million to these entities. The Company has subcontracting arrangements with certain of these entities for the performance of construction services, and expenses recognized in connection with these arrangements totaled approximately $1.2 million and $2.4 million for the three and six month periods ended June 30, 2024, respectively, and totaled approximately $0.7 million and $1.5 million for the three and six month periods ended June 30, 2023, respectively. As of June 30, 2024 and December 31, 2023, related amounts payable to these entities totaled approximately $0.2 million and $0.1 million, respectively. In addition, the Company has advanced amounts to certain of these entities, which for the six month periods ended June 30, 2024 and 2023, totaled approximately $0.1 million and $0.4 million, respectively. As of June 30, 2024 and December 31, 2023, receivables related to these arrangements totaled approximately $4.2 million and $4.0 million, respectively.

Variable Interest Entities. The Company has determined that certain of its investment arrangements are variable interest entities (“VIEs”). Management assesses its VIEs on an ongoing basis to determine if the Company is the primary beneficiary and if consolidation is required. As of June 30, 2024, management determined that the Company is the primary beneficiary of two of its VIEs, and accordingly, has consolidated these entities within the Company’s financial statements, with the other parties’ interests accounted for as a non-controlling interests.

The Company’s consolidated VIEs include an electric utility contractor in which the Company acquired a 49% interest in the first quarter of 2024. As of June 30, 2024 and December 31, 2023, the carrying values of assets associated with the Company’s consolidated VIEs totaled approximately $15.7 million and $1.7 million, respectively, which amounts consisted primarily of accounts receivable, net of allowance and cash. The carrying values of liabilities associated with the Company’s consolidated VIEs totaled approximately $13.8 million and $1.6 million as of June 30, 2024 and December 31, 2023, respectively, which amounts consisted primarily of accounts payable and accrued salaries and wages. The Company has not provided, nor is it obligated to provide, any financial support to any of its consolidated VIEs.

The carrying values of the Company’s VIEs that are not consolidated totaled approximately $24 million and $23 million as of June 30, 2024 and December 31, 2023, respectively, which amounts are recorded within other long-term assets in the consolidated balance sheets. Management believes that the Company’s maximum exposure to loss for its non-consolidated VIEs, inclusive of additional financing commitments, approximated $35 million as of both June 30, 2024 and December 31, 2023.

Senior Notes

As of both June 30, 2024 and December 31, 2023, the gross carrying amount of the Company’s 4.500% senior notes due August 15, 2028 (the “4.500% Senior Notes”) totaled $600.0 million, and their estimated fair value totaled approximately $571.2 million and $565.2 million for the respective periods. As of June 30, 2024, the gross carrying amount of the Company’s 5.900% senior notes due June 15, 2029 (the “5.900% Senior Notes”) totaled $550.0 million, and their estimated fair value totaled approximately $552.2 million. As of June 30, 2024 and December 31, 2023, the gross carrying amount of the Company’s 6.625% senior notes due August 15, 2029 (the “6.625% Senior Notes”) totaled $91.7 million and $284.2 million, respectively, and their estimated fair value totaled approximately $94.6 million and $273.9 million for the respective periods. As of June 30, 2024, the estimated fair values of the Company’s senior notes were determined based on an exit price approach using Level 2 inputs. In the first quarter of 2024, management reevaluated its fair value hierarchy determination for its senior notes to better align with the valuation hierarchy of the fair value guidance, which resulted in an update of the Level determination from Level 1 inputs to Level 2 inputs. The update had no effect on the reported fair values of the related senior notes.

Note 5 – Accounts Receivable, Net of Allowance, and Contract Assets and Liabilities

The following table provides details of accounts receivable, net of allowance, and contract assets (together, “accounts receivable, net”) as of the dates indicated (in millions):


	June 30, 2024		December 31, 2023
Contract billings	$	1,361.9	$	1,385.2
Less allowance	(19.9)		(15.1)
Accounts receivable, net of allowance	$	1,342.0	$	1,370.1

Retainage	$	324.9	$	356.4
Unbilled receivables	1,208.6		1,400.0
Contract assets	$	1,533.5	$	1,756.4

Contract billings represent the amount of performance obligations that have been billed but not yet 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. Unbilled receivables, which are included in contract assets, include amounts for work performed for which the Company has an unconditional right to receive payment and that are not subject to the completion of any other specific task, other than the billing itself. 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. For the six month period ended June 30, 2024, provisions for credit losses totaled approximately $3.9 million, including certain project-specific reserves, and for the six month period ended June 30, 2023, provisions for credit losses totaled a recovery of approximately $0.7 million. Impairment losses on contract assets were not material in either period.

Contract liabilities consist primarily of deferred revenue. Under certain contracts, the Company may be entitled to invoice the customer and receive payments in advance of performing the related contract work. 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 $620.7 million and $481.0 million as of June 30, 2024 and December 31, 2023, respectively, of which deferred revenue comprised approximately $614.5 million and $475.2 million, respectively. The increase in contract liabilities as of June 30, 2024 was driven primarily by ordinary course project activity, including in connection with new project starts within the Company’s Clean Energy and Infrastructure segment. For the six month periods ended June 30, 2024 and 2023, the Company recognized revenue of approximately $374.1 million and $342.2 million, respectively, related to amounts that were included in deferred revenue as of December 31, 2023 and 2022, respectively, resulting primarily from the advancement of physical progress on the related projects during the respective periods.

The Company is party to certain non-recourse financing arrangements in the ordinary course of business, under which certain receivables are sold to a financial institution in return for a nominal fee. Beginning in the third quarter of 2023, the Company entered into certain additional non-recourse financing arrangements under which it continues to manage collections for the transferred receivables, and for which the corresponding servicing assets or liabilities are not material. For the six month period ended June 30, 2024, the Company sold approximately $228 million of receivables under financing arrangements for which it continues to manage collections for the transferred receivable, and, as of June 30, 2024 and December 31, 2023, outstanding sold receivables related thereto totaled approximately $85 million and $64 million, respectively, which amounts are excluded from Accounts Receivable, net of Allowance, in the consolidated balance sheets. The Company’s involvement in the collection process for these receivables is not considered to constitute significant continuing involvement, and, therefore, the receivables are accounted for as a sale under ASC Topic 860, Transfers and Servicing. Cash collections from the sale of receivables are reflected within operating activities in the consolidated statements of cash flows. The Company is also party to arrangements with certain customers that allow for early collection of receivables for a nominal fee, at the Company’s option. Discount charges related to the above described financing arrangements, which are included within interest expense, net, totaled approximately $5.1 million and $4.2 million for the three month periods ended June 30, 2024 and 2023, respectively, and totaled approximately $10.3 million and $8.0 million for the six month periods ended June 30, 2024 and 2023, respectively.

Second Quarter 2024 Debt Transactions

On June 10, 2024, the Company completed an offering of $550 million aggregate principal amount of 5.900% Senior Notes. Interest on the 5.900% Senior Notes is payable semiannually in arrears on June 15 and December 15 of each year, beginning on December 15, 2024. The 5.900% 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 future subordinated indebtedness. The 5.900% Senior Notes are effectively subordinated to all secured indebtedness of the Company, to the extent of the value of the assets securing such indebtedness, and structurally subordinated to all of the obligations of the subsidiaries of the Company, including trade payables. Financing costs incurred in connection with the issuance of the 5.900% Senior Notes totaled approximately $5.9 million, which will be amortized over the term of the 5.900% Senior Notes using the effective interest method.

The Company has the option to redeem all or a portion of the 5.900% Senior Notes at the redemption prices specified in the indenture that governs the 5.900% Senior Notes (the “5.900% Senior Notes Indenture”), plus accrued and unpaid interest, if any, to, but excluding, the redemption date. If a change of control triggering event, as defined in the 5.900% Senior Notes Indenture, occurs, each holder of the 5.900% Senior Notes will have the right to require the Company to repurchase all or any portion of such holder’s 5.900% Senior Notes then outstanding at a price equal to 101% of the principal amount of the 5.900% Senior Notes, plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase, subject to the right of holders of 5.900% Senior Notes on the relevant record date to receive interest due on the relevant interest payment date.

The 5.900% Senior Notes Indenture, among other things, generally limits the ability of the Company and certain of its subsidiaries to create liens, enter into sale and leaseback transactions and effect mergers, subject to certain exceptions. The 5.900% Senior Notes Indenture provides for customary events of default, which include, subject, in certain cases, to customary grace and cure periods, among others, nonpayment of principal or interest; breach of other covenants or agreements in the 5.900% Senior Notes Indenture; failure to pay certain other indebtedness; and certain events of bankruptcy or insolvency. Generally, if an event of default occurs and is continuing, the trustee or holders of at least 25% of the 5.900% Senior Notes then outstanding may declare the principal amount, premium, if any, and accrued interest on all of the 5.900% Senior Notes to be immediately due and payable.

Concurrently with the Company’s offering of the 5.900% Senior Notes, IEA Energy Services LLC (“IEA LLC”), a wholly-owned subsidiary of the Company, launched a tender offer and consent solicitation (the “IEA Tender”) for IEA LLC’s 6.625% senior notes due 2029 (the “6.625% IEA Senior Notes”). The Company used a portion of the proceeds from the 5.900% Senior Notes offering to purchase $203.7 million in aggregate principal amount of 6.625% IEA Senior Notes tendered at a price equal to 100.0% of the principal amount of the 6.625% IEA Senior Notes, plus accrued and unpaid interest to, but excluding, the payment date. In July 2024, subsequent to the IEA Tender, IEA LLC exercised its right under the indenture that governs the 6.625% IEA Senior Notes to redeem the remaining $21.4 million in aggregate principal amount of the 6.625% IEA Senior Notes at a price equal to 95.0% of the principal amount of the 6.625% IEA Senior Notes redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

The remaining net proceeds from the 5.900% Senior Notes offering were used, along with available cash, for the repayment of the Company’s $400.0 million Three-Year Term Loan Facility. The Company recorded a pre-tax debt extinguishment loss of approximately $11.3 million in the second quarter of 2024 in connection with these transactions, which is separately presented within the Company’s consolidated statements of operations.

Note 10 – 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 June 30, 2024 and 2023, the Company’s consolidated effective tax rates were 30.7% and 14.9%, respectively, and for the six month periods ended June 30, 2024 and 2023 were 47.0% and 39.6%, respectively. The Company’s effective tax rate for the six month period ended June 30, 2024 included the effect of an increase in non-deductible expenses as compared with the same period in 2023. For the six month period ended June 30, 2023, the Company’s effective tax rate included a net tax benefit of approximately $8.9 million related to share-based payment awards and a benefit from certain prior period tax return adjustments.

Note 11 – Segments and Related Information

Segment Discussion

The Company manages its operations under five operating segments, which represent its five reportable segments: (1) Communications; (2) Clean Energy and Infrastructure; (3) Power Delivery; (4) Oil and Gas and (5) Other. This structure is generally focused on broad end-user markets for the Company’s labor-based construction services. The Company’s reportable segments derive their revenue primarily 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, as well as infrastructure for utilities, among others. The Clean Energy and Infrastructure segment primarily serves energy, utility, government and other end-markets through the installation and construction of power generation facilities, primarily from clean energy and renewable sources, such as wind, solar, biomass, natural gas and hydrogen, as well as battery storage systems for renewable energy; various types of heavy civil and industrial infrastructure, including roads, bridges and rail; and environmental remediation services. The Power Delivery segment primarily serves the energy and utility industries through the engineering, construction and maintenance of power transmission and distribution infrastructure, including electrical and gas transmission lines, distribution network systems and substations; and environmental planning and compliance services. The Oil and Gas segment performs engineering, construction, maintenance and other services for pipeline infrastructure, including natural gas, water and carbon capture sequestration pipelines, as well as pipeline integrity and other services for the energy and utilities industries. The Other segment includes certain equity investees, the services of which may vary from those provided by the Company’s primary segments, as well as other small business units with activities in certain 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 additional financial measures, including EBITDA. The Company believes these additional financial 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, or underlying, operating results for its reportable segments, as well as items that can vary widely across different industries or among companies within the same industry. Management also uses these additional financial measures, including EBITDA, to allocate resources. 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.

Significant Customers

No customer represented greater than 10% of the Company’s total consolidated revenue in any of the three or six month periods ended June 30, 2024 and 2023.

Note 12 – 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 other project disputes, other project-related liabilities 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.

Acquired Legacy Solar Matter

See Note 14 – Commitments and Contingencies contained within the Company’s audited consolidated financial statements filed with its 2023 Form 10-K for additional information regarding the acquired legacy solar matter, as to which there have been no material developments since the filing of such Form 10-K.

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 certain related party leases. See Note 7 – Lease Obligations and Note 13 – 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 June 30, 2024 and December 31, 2023, there were $83.9 million and $82.1 million, respectively, of letters of credit issued under the Company’s credit facilities. Letter of credit claims have historically not been material. The Company is not aware of any material claims relating to its outstanding letters of credit as of June 30, 2024 or December 31, 2023.

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 June 30, 2024 and December 31, 2023, outstanding performance and payment bonds approximated $6.7 billion and $5.6 billion, respectively, and estimated costs to complete projects secured by these bonds totaled $2.1 billion and $1.6 billion, respectively. Included in these balances as of June 30, 2024 and December 31, 2023 are $825.2 million and $368.3 million, respectively, of outstanding performance and payment bonds issued on behalf of the Company’s proportionately consolidated non-controlled contractual joint ventures, representing the Company’s proportionate share of the total bond obligation for the related projects.

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, as well as undivided interests, ranging from 25% to 50%, in each of five civil construction projects. Income and/or loss incurred by these joint ventures is 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 June 30, 2024, the Company was not aware of material future claims against it in connection with these arrangements. Included in the Company’s cash balances as of June 30, 2024 and December 31, 2023 are amounts held by entities that are proportionately consolidated totaling $62.8 million and $38.1 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 and Note 13 – Related Party Transactions for additional information pertaining to the Company’s 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. The Company manages certain of its insurance liabilities indirectly through its wholly-owned captive insurance company, which reimburses claims up to the applicable insurance limits. Captive insurance-related cash balances totaled approximately $2.1 million and $1.2 million as of June 30, 2024 and December 31, 2023, respectively, which amounts are generally not available for use in the Company’s other operations.

MasTec’s estimated liability for unpaid claims and associated expenses, including incurred but not reported losses related to these policies, totaled $217.6 million and $209.7 million as of June 30, 2024 and December 31, 2023, respectively, of which $153.7 million and $141.0 million was reflected within other long-term liabilities in the consolidated balance sheets for the respective periods. 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 $5.5 million and $4.1 million as of June 30, 2024 and December 31, 2023, 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 $9.1 million and $9.6 million as of June 30, 2024 and December 31, 2023, respectively. Outstanding surety bonds related to self-insurance programs amounted to $190.0 million and $192.7 million as of June 30, 2024 and December 31, 2023, respectively.

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 both June 30, 2024 and December 31, 2023, the Company had accrued project close-out liabilities of approximately $20 million. The Company is not aware of any other material asserted or unasserted claims in connection with its potential indemnity obligations.

Other Guarantees. From time to time in the ordinary course of its business, 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 following substantial completion of a project. Much of the work performed by the Company is evaluated for defects shortly after the work is completed. 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 1,080 customers for the six month period ended June 30, 2024. As of June 30, 2024, no customer represented greater than 10% of the Company’s consolidated net accounts receivable position, which is calculated as accounts receivable, net, less deferred revenue. As of December 31, 2023, one customer accounted for approximately 10% of the Company’s consolidated net accounts receivable position. The Company derived approximately 36% and 35%, respectively, of its revenue from its top ten customers for the three month periods ended June 30, 2024 and 2023, and derived approximately 39% and 36% of such revenue for the six month periods ended June 30, 2024 and 2023, respectively.

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

The following is a discussion and analysis of our business, financial condition and results of operations for the quarterly period ended June 30, 2024 and relevant prior periods. 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 2023 Form 10-K. In this MD&A, “$” means U.S. dollars unless specified otherwise.

General Economic, Market and Regulatory Conditions

We have experienced, and may continue to experience, direct and indirect negative effects on our business and operations from economic, market and regulatory conditions. We expect the remainder of 2024 to continue to be a dynamic macroeconomic environment, with elevated market interest rates and continuing levels of cost inflation and potential market volatility, any or all of which could adversely affect our costs and customer demand. The extent to which general economic, market and regulatory conditions could affect our business, operations and financial results is uncertain as it will depend upon numerous evolving factors that we may not be able to accurately predict, and, therefore, any future impacts on our business, financial condition and/or results of operations cannot be quantified or predicted with specificity. For additional information regarding the effects of general economic, market and regulatory conditions, see Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our 2023 Form 10-K.

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; power delivery infrastructure, including transmission, distribution, environmental planning and compliance; power generation infrastructure, primarily from clean energy and renewable sources; pipeline infrastructure, including for natural gas, water and carbon capture sequestration pipelines and pipeline integrity services; heavy civil and industrial infrastructure, including roads, bridges and rail; and environmental remediation services. Our customers are primarily in these industries. Including our predecessor companies, we have been in business for approximately 95 years. For the twelve month period ended June 30, 2024, we had an average of approximately 34,000 employees and 820 locations. We offer our services under the MasTec® and other service marks and we are ranked among the top five contractors within Engineering News-Record’s Top 400 Contractors.

We provide our services to a diversified base of customers and a significant portion of our services are provided 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) Clean Energy and Infrastructure; (3) Power Delivery; (4) Oil and Gas; and (5) Other. This structure is generally focused on broad end-user markets for our labor-based construction services. See Note 11 – Segments and Related Information and Note 12 – Commitments and Contingencies in the notes to the consolidated financial statements, which are incorporated by reference, for additional information regarding our segment reporting 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 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 anticipate that we will realize approximately 45% of our estimated June 30, 2024 backlog in 2024. The following table presents 18-month estimated backlog by reportable segment as of the dates indicated:


Reportable Segment (in millions):	June 30, 2024		March 31, 2024		June 30, 2023
Communications	$	5,898	$	5,797	$	5,420
Clean Energy and Infrastructure	3,666		3,504		3,324
Power Delivery	2,974		2,479		2,656
Oil and Gas	800		1,057		2,042
Other	—		—		—
Estimated 18-month backlog	$	13,338	$	12,837	$	13,442

As of June 30, 2024, 54% of our backlog is estimated to be 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, regulatory or other delays or cancellations, including from factors relative to “General Economic, Market and Regulatory Conditions” mentioned above. These effects, among others, 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 due to these effects and/or other factors. There can be no assurance as to our customers’ requirements or that actual results will be consistent with the estimates included in our 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 June 30, 2024, total 18-month backlog differed from the amount of our remaining performance obligations due primarily to the inclusion of $7.2 billion of estimated future revenue under master service and other service agreements within our backlog estimates, as described above, and the exclusion of approximately $3.2 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 2024 differs from the amount of remaining performance obligations expected to be recognized for the same period due primarily to the inclusion of approximately $1.8 billion of estimated future revenue under master service and other service agreements included within our backlog estimate, which is not included within our remaining performance obligations for the same period.

Economic, Industry and Market Factors

We closely monitor the effects of changes in economic, industry and market conditions on our customers, which can affect demand for our customers’ products and services and can increase or decrease our customers’ planned capital and maintenance budgets in certain end-markets. Any of these factors and effects, as well as mergers and acquisitions or other business transactions among the customers we serve, could affect demand for our services, or the cost to provide such services and our profitability. For additional information regarding the potential effects of economic, industry and market factors on our business, see Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our 2023 Form 10-K.

Effect of Seasonality and Cyclical Nature of Business

Our revenue and results of operations are cyclical and can be subject to seasonal and other variations. For additional information regarding the effects of seasonality and the cyclical nature of our business, see Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our 2023 Form 10-K.

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 accompanying notes. A summary of our critical accounting estimates is included in Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our 2023 Form 10-K. We are required to make estimates and judgments in the preparation of our financial statements that affect the reported amounts of assets and liabilities, revenues and expenses and related disclosures. We continually review these estimates and their underlying assumptions to ensure they are appropriate for the circumstances. Changes in the estimates and assumptions we use could have a material impact on our financial results.

In connection with the restructuring in the first quarter of 2024 of the reporting units in the Power Delivery segment, management performed a quantitative assessment of the goodwill associated with each of the five reporting units of the Power Delivery operating segment. For additional details of the restructuring and the related assessment, refer to Note 3 – Acquisitions, Goodwill and Other Intangible Assets, Net, in the notes to the consolidated financial statements, which is incorporated by reference.

There were no material changes in our critical accounting estimates or policies during the three month period ended June 30, 2024, and other than the update to the reporting unit structure of the Power Delivery operating segment as described above, there were no material changes during the six month period ended June 30, 2024.

Results of Operations

Comparison of Quarterly Results

The following table, which may contain slight summation differences due to rounding, reflects our consolidated results of operations in dollar and percentage of revenue terms for the periods indicated (dollar amounts in millions). Our consolidated results of operations are not necessarily comparable from period to period due to the effect of recent acquisitions and certain other items, which are described in the comparison of results section below.

Power Delivery revenue was $637 million for the three month period ended June 30, 2024, as compared with $703 million for the same period in 2023, a decrease of $66 million, or 9%. The decrease in revenue was primarily due to lower levels of project activity, including timing-related decreases in transmission and distribution-related project work, primarily due to regulatory effects, offset, in part, by an increase in substation-related project activity.

Oil and Gas Segment. Oil and Gas revenue was $572 million for the three month period ended June 30, 2024, as compared with $342 million for the same period in 2023, an increase of $231 million, or 67%, due primarily to higher levels of project activity, including from increased demand and project timing-related increases in large-diameter and midstream project activity due to improved market and regulatory conditions, partially offset by a reduction in pipeline integrity services.

Costs of revenue, excluding depreciation and amortization. Costs of revenue, excluding depreciation and amortization, increased by approximately $56 million, or 2%, to $2,540 million for the three month period ended June 30, 2024 from $2,485 million for the same period in 2023. Higher levels of revenue contributed an increase of $75 million in costs of revenue, excluding depreciation and amortization, whereas improved productivity resulted in a decrease of approximately $20 million. Costs of revenue, excluding depreciation and amortization, as a percentage of revenue decreased by approximately 70 basis points to 85.8% of revenue for the three month period ended June 30, 2024 from 86.5% of revenue for the same period in 2023. The basis point decrease was due to a combination of improved project efficiencies and project mix, primarily within our Oil and Gas and Clean Energy and Infrastructure segments, and the positive effects of certain project close-outs, offset, in part, by reduced productivity from the effects of certain overhead costs incurred to maintain operating capacity in support of expected future project work. See “Analysis of EBITDA by Segment” below for discussion of operating capacity effects by segment.

Depreciation. Depreciation was $102 million, or 3.4% of revenue, for the three month period ended June 30, 2024, as compared with $103 million, or 3.6% of revenue, for the same period in 2023. As a percentage of revenue, depreciation decreased by approximately 10 basis points, due primarily to higher levels of revenue.

Amortization of intangible assets. Amortization of intangible assets was $34 million, or 1.1% of revenue, for the three month period ended June 30, 2024, as compared with $42 million, or 1.5% of revenue, for the same period in 2023, a decrease of approximately $8 million, or 20%, due to a combination of the effects of timing of amortization for certain assets and the completion of amortization for certain intangible assets associated with prior year acquisitions. As a percentage of revenue, amortization of intangible assets decreased by approximately 30 basis points as compared with the same period in 2023.

General and administrative expenses. General and administrative expenses totaled $167 million, or 5.6% of revenue, for the three month period ended June 30, 2024, as compared with $176 million, or 6.1% of revenue, for the same period in 2023, a decrease of approximately $9 million, or 5%. The decrease in general and administrative expenses was primarily due to a $20 million reduction in acquisition and integration costs, an increase in gains on sales of assets, net, and a decrease in various administrative costs, including information technology expenses, offset, in part, by increases in compensation and the effects of timing of ordinary course legal matters. Overall, general and administrative expenses decreased by approximately 50 basis points as a percentage of revenue for the three month period ended June 30, 2024 as compared with the same period in 2023.

Corporate EBITDA was negative $118 million for the six month period ended June 30, 2024, as compared with EBITDA of negative $90 million for the same period in 2023, for a decrease in EBITDA of approximately $28 million. For the six month period ended June 30, 2024, Corporate EBITDA included approximately $11 million of a loss on debt extinguishment and $2 million of income, net, from changes to estimated Earn-out accruals. For the six month period ended June 30, 2023, Corporate EBITDA included approximately $2 million of income, net, from changes to estimated Earn-out accruals and $3 million of income from the final settlement and expiration of certain warrants related to the acquisition of IEA. Corporate expenses for the six month period ended June 30, 2024 not related to the above-described items increased by approximately $14 million as compared with the same period in 2023, due primarily to increases in information technology and other administrative expenses as well as the effects of timing of ordinary course legal and other settlement matters.

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 respective periods, non-cash stock-based compensation expense; the loss on debt extinguishment; acquisition and integration costs related to certain acquisition activity; and fair value gains or losses, net, on an investment; and, for Adjusted Net Income and Adjusted Diluted Earnings Per Share, amortization of intangible assets and the tax effects of the adjusted items. 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, or underlying, operating results, as well as items that can vary widely across different industries or among companies within the same industry. We believe that these adjusted measures provide a baseline for analyzing trends in our underlying business. We also use these adjusted measures to allocate resources. 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. In 2021, we initiated a significant transformation of our end-market business operations to focus on the nation’s transition to low-carbon energy sources and position the Company for expected future opportunities. This transformation included significant acquisition activity to expand our scale and capacity in renewable energy, power delivery, heavy civil and telecommunications services, and resulted in significant acquisition and integration costs. Due to the extent of the acquisition costs related to this acquisition activity and the extent of the efforts that were required to integrate these acquisitions, we have excluded acquisition and integration costs related to this acquisition activity in our computation of Adjusted EBITDA, Adjusted Net Income and Adjusted Diluted Earnings Per Share. These acquisition and integration activities were completed in the fourth quarter of 2023.

Our adjusted results also exclude fair value gains or losses, net, for our investment in American Virtual Cloud Technologies, Inc. (“AVCT”). We believe that fair value gains or losses for our investment in AVCT, a company in which we had no active involvement and for which fair value activity varied from period to period based on fluctuations in the market price of the investment, are not indicative of our core operations, and that this presentation improves comparability of our results with those of our peers. AVCT filed for bankruptcy in the first quarter of 2023, and our investment was fully written off.

We exclude intangible asset amortization from our non-U.S. GAAP financial measures due to its non-operational nature and inherent volatility, as acquisition activity varies from period to period. We believe that this presentation is common practice within our industry and improves comparability of our results with those of our peers. Note that while intangible asset amortization related to the assets of acquired entities is excluded

from our non-U.S. GAAP financial measures, the revenue and all other expenses of the acquired entities are included within our non-U.S. GAAP financial measures, unless otherwise stated.

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. Each company’s definitions of these adjusted measures may vary as they are not standardized and should be used together with the provided reconciliations. 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.

(a) Represents the tax effects of the adjusted items that are subject to tax, including the tax effects of non-cash stock-based compensation expense, including from share-based payment awards. 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 effects on pre-tax income. For the three and six month periods ended June 30, 2024, our consolidated tax amounts were expenses, with effective tax rates, as reported, of 30.7% and 47.0%, respectively, and as adjusted, were expenses with effective tax rates of 25.6% and 27.1%. respectively. For the three and six month periods ended June 30, 2023, our consolidated effective tax amounts were an expense and a benefit, with effective tax rates, as reported, of 14.9% and 39.6%, respectively, and as adjusted, were expenses with effective tax rates of 23.9% and 18.9%. respectively.

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, debt service, income taxes, earn-out obligations and equity and other investment funding requirements. We also evaluate opportunities for strategic acquisitions, investments and other arrangements from time to time, and we may consider opportunities to refinance, extend the terms of our existing indebtedness, retire outstanding debt, borrow additional funds, which may include borrowings under our Credit Facility or debt issuances, or repurchase additional shares of our outstanding common stock under share repurchase authorizations, any of which may require our use of cash. See Note 6 – Debt in the notes to the consolidated financial statements in this Form 10-Q, which is incorporated by reference, for details of our $550 million offering of 5.900% Senior Notes and the repayments of our 6.625% Senior Notes and Three-Year Term Loan during the second quarter of 2024.

Capital Expenditures. For the six month period ended June 30, 2024, we spent approximately $57 million on capital expenditures, or $26 million, net of asset disposals, and incurred approximately $53 million of equipment purchases under finance leases and other financing arrangements. We estimate that we will spend approximately $175 million on capital expenditures, or approximately $125 million, net of asset disposals, in 2024, and we expect to incur approximately $150 million of equipment purchases under finance leases and other financing arrangements. Actual capital expenditures may increase or decrease in the future depending upon business activity levels, as well as ongoing assessments of equipment lease and other financing arrangements versus purchase decisions based on management’s evaluation of short and long-term equipment requirements.

Acquisitions and Earn-Out Liabilities. We typically utilize cash for business acquisitions and other strategic arrangements. 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. Additionally, from time to time, our acquisitions may contain certain additional payments based upon specified conditions. Earn-out payments may be paid in cash or, under specific circumstances, MasTec common stock, or a combination thereof, generally at our option. The estimated total value of future Earn-out liabilities as of June 30, 2024 was approximately $71 million. Of this amount, approximately $24 million represents the liability for earned amounts. The remainder is management’s estimate of Earn-out

liabilities that are contingent upon future performance. For the six month periods ended June 30, 2024 and 2023, we made $5 million and $26 million, respectively, of payments related to our Earn-out liabilities.

Income Taxes. For the six month periods ended June 30, 2024 and 2023, tax payments, net of tax refunds totaled approximately $45 million and $14 million, respectively. 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 and other variations in our business, primarily related to the effects of weather conditions on outdoor construction and maintenance work and the spending patterns of our customers, both of which influence the timing of associated spending to support 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 and materials requirements, typically become payable before the receivables resulting from work performed are collected. The timing of billings and project close-outs can also contribute to changes in billed and unbilled revenue. As of June 30, 2024, 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, totaled approximately $2.9 billion as of June 30, 2024 as compared with $3.1 billion as of December 31, 2023, due primarily to a decrease in quarterly revenue.

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 until the job is completed, which amounts are referred to as “retainage.” 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 are contractually due to subcontractors only after we are paid by our customers.

Summary of Financial Condition, Liquidity and Capital Resources

Including our current assessment of general economic and market conditions on our results of operations and capital resource requirements, we anticipate that funds generated from operations, borrowings under our credit facilities 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, as well as potential acquisition, strategic arrangement and investment funding requirements and/or share repurchase activity and other liquidity needs for the next twelve months and the foreseeable future.

Sources and Uses of Cash

As of June 30, 2024, we had approximately $729 million in working capital, defined as current assets less current liabilities, as compared with $1,137 million as of December 31, 2023, a decrease of approximately $408 million. Cash and cash equivalents totaled approximately $298 million and $530 million as of June 30, 2024 and December 31, 2023, respectively, for a decrease of approximately $232 million. See discussion below for further detail regarding our cash flows and related activity.

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


	For the Six Months Ended June 30,
	2024		2023
Net cash provided by (used in) operating activities	$	372.2	$	(97.9)
Net cash used in investing activities	$	(24.5)	$	(141.5)
Net cash used in financing activities	$	(579.1)	$	(12.2)

Operating Activities. Cash flow from operations is primarily influenced by changes in the timing of demand for our services and operating margins, but can 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, accrued expenses and 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 six month period ended June 30, 2024 was $372 million, as compared with $98 million of net cash used in operating activities for the same period in 2023, for an increase in net cash provided by operating activities of approximately $470 million, due primarily to (i) changes in working capital compared with the prior period, including from the positive effect of timing-related changes in accounts receivable, offset, in part, by the negative effect of timing-related changes in accounts payable and accrued expenses; and (ii) an increase in net income as compared with the prior period.

Days sales outstanding, net of contract liabilities, which we refer to as “DSO,” is calculated as total accounts receivable, net of allowance, less contract liabilities, divided by average daily revenue for the most recently completed quarter as of the balance sheet date. Our DSO was 69 as of June 30, 2024 as compared with DSO of 74 as of December 31, 2023. Our 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, including certain accounts receivable financing arrangements. The decrease in DSO as of June 30, 2024 as compared with December 31, 2023 was due to timing of ordinary course billing and collection activities, as well as the effects of certain accounts receivable financing arrangements. Other than ordinary course 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 information, 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 by approximately $117 million to $24 million for the six month period ended June 30, 2024 from $141 million for the same period in 2023. Capital expenditures totaled $57 million, or $26 million, net of asset disposals, for the six month period ended June 30, 2024, as compared with $119 million, or $76 million, net of asset disposals, for the same period in 2023, for a decrease in cash used in investing activities of approximately $51 million, due primarily to timing of equipment purchases. Cash used in investing activities from acquisition activity decreased by $64 million for the six month period ended June 30, 2024 as compared with the same period in 2023.

Financing Activities. Net cash used in financing activities for the six month period ended June 30, 2024 was $579 million, as compared with $12 million for the same period in 2023, for an increase in cash used in financing activities of approximately $567 million. The increase was primarily due to repayments, net of borrowings, of our credit facility and term loans, which increased by $932 million for the six month period ended June 30, 2024 as compared with the same period in 2023, and the repayment of $204 million of our 6.625% Senior Notes in the second quarter of 2024. These repayments were partially offset by $550 million of net proceeds received in the second quarter of 2024 from the issuance of our 5.900% Senior Notes.

Senior Credit Facility

We have a $2.25 billion senior unsecured credit facility (as amended from time to time, the “Credit Facility”), which is composed of $1.9 billion of revolving commitments and a Term Loan with an original principal amount of $350 million, and matures on November 1, 2026. As of June 30, 2024, aggregate outstanding revolving borrowings totaled approximately $0.4 billion and availability for revolving loans totaled $1.5 billion. Borrowings under our Credit Facility are used for working capital requirements, capital expenditures and other corporate purposes, including acquisitions, equity investments or other strategic arrangements, and/or the repurchase or prepayment of indebtedness, among other corporate borrowing requirements, including potential share repurchases.

We are dependent upon borrowings and letters of credit under our Credit Facility to fund our operations. Should we be unable to comply with the terms and conditions of 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 2023 Form 10-K.

4.500% Senior Notes

We have $600 million aggregate principal amount of 4.500% senior unsecured notes due August 15, 2028 (the “4.500% Senior Notes”). The 4.500% Senior Notes are 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 2023 Form 10-K.

5.900% Senior Notes

On June 10, 2024, we completed an offering of $550 million aggregate principal amount of 5.900% senior unsecured notes due June 15, 2029 (the “5.900% Senior Notes”). We used a portion of the proceeds from the 5.900% Senior Notes offering to purchase $204 million in aggregate principal amount of 6.625% IEA Senior Notes tendered at a price equal to 100.0% of the principal amount of the 6.625% IEA Senior Notes. The remaining net proceeds from the 5.900% Senior Notes offering were used, along with available cash, for the repayment of the Company’s $400.0 million Three-Year Term Loan Facility. See Note 6 – Debt in the notes to the consolidated financial statements, which is incorporated by reference.

6.625% Senior Notes

We have $96 million aggregate principal amount of 6.625% senior unsecured notes due August 15, 2029 (the “6.625% Senior Notes”), which are composed of $21 million aggregate principal amount of 6.625% IEA senior notes (the “6.625% IEA Senior Notes”) and $75 million aggregate principal amount of 6.625% MasTec senior notes (the “6.625% MasTec Senior Notes”). In July 2024, IEA LLC exercised its right under the indenture that governs the 6.625% IEA Senior Notes to redeem the remaining $21 million in aggregate principal amount of the 6.625% IEA Senior Notes at a price equal to 95.0% of the principal amount. The remaining 6.625% MasTec Senior Notes are 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 2023 Form 10-K.

Five-Year Term Loan Facility

As of June 30, 2024, we had $292.5 million outstanding of an unsecured five-year term loan (the “Five-Year Term Loan”) that is due October 7, 2027. The Five-Year Term Loan 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 2023 Form 10-K.

Debt Covenants

We were in compliance with the provisions and covenants contained in our outstanding debt instruments as of June 30, 2024, and we expect to be in compliance with these provisions and covenants for the next twelve months.

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 2023 Form 10-K. Also, see Note 6 – Debt in the notes to the consolidated financial statements in this Form 10-Q, which is incorporated by reference, for current period balances, rates of interest and related discussion.

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. These off-balance sheet arrangements have not had, and are not reasonably likely to have, a material impact on our financial condition, revenue or expenses, results of operations, liquidity, cash requirements or capital resources in the next twelve months or in the foreseeable future. Refer to Note 12 – Commitments and Contingencies, Note 4 – Fair Value of Financial Instruments and Note 13 – Related Party Transactions in the notes to the consolidated financial statements in this Form 10-Q, which are incorporated by reference, and see Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our 2023 Form 10-K for additional information related to our off-balance sheet arrangements.

Impact of Inflation

Over the past years, inflation, supply chain and labor constraints have had a significant impact on the global economy, including on the construction industry in the United States. We expect elevated market interest rates and continuing levels of cost inflation for the foreseeable future. Elevated levels of labor, material and fuel costs have negatively affected our project margins to the extent that we have been unable to pass such cost increases along to our customers. If current inflationary conditions persist, our profitability could continue to be affected in the future. Market and economic volatility and/or uncertainty can also affect our customers’ investment decisions and subject us to project cancellations, deferrals or unexpected changes in the timing of project work. Additionally, as discussed within “Interest Rate Risk” below, the current inflationary environment has resulted in an increase in market interest rates, which has increased the rates of interest on our variable rate debt and, correspondingly, our interest expense. Increased market interest rates could also have an adverse effect on the capital expenditure budgets of our customers, which could result in reduced or deferred demand for our services.

We closely monitor inflationary factors, including current rates of inflation and any potential effects they may have on our business operations, operating results and/or financial condition. While the impact of these factors cannot be fully eliminated, we proactively work to mitigate their effects; however, inflationary pressures and interest rate increases could adversely affect our business operations in the future. For additional information regarding the effects of inflation on our business, see Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our 2023 Form 10-K.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

Our interest expense is affected by the overall interest rate environment. We manage interest rate risk by maintaining a mix of fixed and variable rate debt obligations. Our variable rate debt subjects us to risk from increases in prevailing interest rates. As of June 30, 2024, our variable rate debt consisted primarily of approximately $360 million of revolving loans outstanding under our Credit Facility with a weighted average interest rate of 6.81%, a $337 million Term Loan under our Credit Facility with a weighted average interest rate of 6.82%, and a $293 million Five-Year Term Loan with a weighted average interest rate of 6.25%. An additional 100 basis point increase in the applicable interest rates under our Credit Facility and Five-Year Term Loan would have increased our interest expense by approximately $6 million for the six month period ended June 30, 2024.

As of June 30, 2024, our fixed rate debt primarily included $600 million aggregate principal amount of 4.500% Senior Notes, $550 million aggregate principal amount of 5.900% Senior Notes, $96 million aggregate principal amount of 6.625% Senior Notes and $291 million of finance lease obligations, which accrued interest at a weighted average interest rate of 4.8%. None of this fixed rate 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 approximately 1% of our total revenue for the six month period ended June 30, 2024. 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 and for our foreign operations with a functional currency other than the local currency. Such activity was not material to our operations for the six month period ended June 30, 2024. 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. For the six month period ended June 30, 2024, foreign currency translation losses, net, totaled approximately $1.4 million and related primarily to our activities in Canada and Mexico.

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 June 30, 2024. We may enter into foreign currency derivative contracts in the future to manage such exposure.

Other Market Risk

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 June 30, 2024.

Changes in Internal Control Over Financial Reporting. There have been no changes in the Company’s internal control over financial reporting during the quarter ended June 30, 2024 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

Refer to Note 12 – 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 2023 Form 10-K.

MasTec has elected to use a $1 million threshold for disclosing proceedings arising under federal, state or local environmental laws, which proceedings involve potential monetary sanctions, and in which a governmental authority is a party. MasTec believes proceedings under this threshold are not material to its business and financial condition.

ITEM 1A. RISK FACTORS

Subject to the potential effects of general economic and market conditions, including levels of inflation, interest rates and other market and geopolitical conditions, including regulatory matters, political unrest and military conflicts, on certain of the risks we normally face in operating our business, including those disclosed in our 2023 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 2023 Form 10-K, as updated by our Quarterly Reports on Form 10-Q and other filings we make with the SEC.
