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 North American infrastructure engineering and construction company focused primarily on engineering, building, installation, maintenance and upgrade of communications, energy and utility and other infrastructure, such as: wireless, wireline/fiber; power delivery infrastructure, including transmission, distribution, grid hardening and modernization, 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) Pipeline Infrastructure 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, 2024 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, 2024 contained in the Company’s 2024 Annual Report on Form 10-K (the “2024 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. When appropriate, prior year amounts are reclassified to conform with the current period presentation. Interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. The Company believes that the disclosures made in these consolidated financial statements are adequate to make the information not misleading.
In the first quarter of 2025, the Company made changes to its Communications segment and Power Delivery segment structures to more closely align with the segments’ end markets and to better correspond with the operational management reporting structures of both segments. These changes included moving a component with utility operations previously reported in the Communications segment to the Power Delivery segment. These changes did not impact the Company’s consolidated financial statements, but did impact its reportable segments, including historical financial information. See Note 10 – Segments and Related Information for additional information pertaining to the Company’s reportable segments. The segments are reported on a comparable basis for all periods presented.
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 and revenue and expenses are translated at average rates of exchange during the applicable period, with resulting translation gains or losses included within other comprehensive income or loss. 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.
9
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 43 % and 41 % of consolidated revenue for the three months ended September 30, 2025 and 2024, respectively, and totaled 45 % and 40 % for the nine months ended September 30, 2025 and 2024, 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. 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 1 % and 2 % of consolidated revenue for the three months ended September 30, 2025 and 2024, respectively, and totaled approximately 1 % and 2 % for the nine months ended September 30, 2025 and 2024, respectively.
The total transaction price and cost estimation processes used for recognizing revenue over time under the cost-to-cost method are 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 estimated. For the nine months ended September 30, 2025, 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, 2024. For the nine months ended September 30, 2024, excluding the effects on the Company’s results of operations from margin increases for two projects within the Company’s Clean Energy and Infrastructure segment totaling $10.0 million, 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. 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 0.6 % and 0.5 % for the three months ended September 30, 2025 and 2024, respectively, and such net changes positively affected revenue by approximately 1.0 % and 0.3 % for the nine months ended September 30, 2025 and 2024, 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 September 30, 2025, the amount of the Company’s remaining performance obligations was $11.7 billion. Based on current expectations, the Company anticipates it will recognize approximately $3.0 billion, or 25.6 %, of its remaining performance obligations as revenue during 2025, 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 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 September 30, 2025 and December 31, 2024, the Company’s contract transaction prices included approximately $211 million and $139 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 September 30, 2025, these change orders and/or claims primarily related to certain projects in the Company’s Clean Energy and Infrastructure and Pipeline Infrastructure segments, whereas as of December 31, 2024, such activity 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.
Supplier Financing Program
The Company has provided certain of its suppliers with access to a supplier finance program administered through a third party, which facilitates participating suppliers’ ability to finance payments due from the Company through third-party financial institutions. Participating suppliers may, at their sole discretion, receive payment of the Company’s obligation prior to the scheduled due dates, at a discounted price from the third party. The Company agrees to pay the financial institution the stated amount generally within 60 days of receipt of the invoice. The Company’s obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by the supplier’s decision to finance amounts under these arrangements. The Company does not have pledged assets or other guarantees under the program. As of September 30, 2025
10
and December 31, 2024, the outstanding payment obligations under the Company’s supplier finance program totaled approximately $112.6 million and $12.4 million, respectively, which amounts are recorded within accounts payable in the consolidated balance sheets. The associated payments are included within operating activities in the consolidated statements of cash flows.
Recent Accounting Pronouncements
The discussion below describes the effects of recent accounting pronouncements, as updated from the discussion in the Company’s 2024 Form 10-K.
In August 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 addressed the accounting for contributions made to a joint venture upon formation in a joint venture’s separate financial statements. The provisions of this ASU required that a joint venture initially measure all contributions received upon its formation at fair value, largely consistent with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations (“ASC 805”). The amendments in this ASU were not applicable to the formation of proportionately consolidated joint ventures. ASU 2023-05 was 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 prospective adoption of this ASU did not have a material effect on the Company’s consolidated financial statements.
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 has determined that the effects of adopting this ASU will only impact its disclosures and the Company does not expect that it will have a material effect on its consolidated financial statements or results of its operations when adopted.
In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”) to enhance the transparency and clarity of the components of specific expense categories in the income statement. ASU 2024-03 requires disclosure of additional information about specific expense categories underlying certain income statement expense line items. In January 2025, the FASB issued ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses: Clarifying the Effective Date to clarify that all public business entities are required to adopt the guidance in annual periods beginning after December 15, 2026, and interim periods within annual periods beginning after December 15, 2027. Early adoption is permitted. The amendments in ASU 2024-03, and its related clarifying ASU, should be applied prospectively, with retrospective application permitted. The Company is currently evaluating the impact this standard will have on its disclosures.
In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity (“ASU 2025-03”). ASU 2025-03 clarifies the guidance in determining the accounting acquirer in a business combination effected primarily by exchanging equity interests when the acquiree is a variable interest entity that meets the definition of a business. ASU 2025-03 is effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years, with early adoption permitted. ASU 2025-03 is required to be applied prospectively to any acquisition transaction that occurs after the initial application date. The Company does not expect that this ASU will have a material 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.

During the first quarter of 2025, certain reporting units within the Communications and Power Delivery operating segments were restructured to more closely align with the segment’s end markets and to better correspond with the operational management reporting structure of both segments. Under both the current and previous reporting unit structures, each of the components within the Communications and Power Delivery operating segments is a reporting unit. Management performed testing under both the current and previous reporting unit structures. For the tested reporting units, management estimated their fair values using a combination of market and income approaches using Level 3 inputs. Under the market approach, fair values were estimated using published market multiples for comparable companies and applying them to revenue and
12
earnings before interest, taxes, depreciation and amortization (“EBITDA”). Under the income approach, a discounted cash flow methodology was used, considering: (i) management estimates, such as projections of revenue, operating costs and cash flows, taking into consideration historical and anticipated financial results; (ii) general economic, market and regulatory conditions; and (iii) the impact of planned business and operational strategies. Management believes the assumptions used in its quantitative goodwill impairment tests are reflective of the risks inherent in the respective industries and business models of the applicable reporting units. Estimated discount rates were determined using the weighted average cost of capital for each reporting unit at the time of the analysis, taking into consideration the risks inherent within each reporting unit individually.
Based on the results of the quantitative assessments, the estimated fair values of all the impacted reporting units substantially exceeded their carrying values as of March 31, 2025, therefore no goodwill impairment existed. 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.
During the three months ended September 30, 2025, no events occurred 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 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. The goodwill balances for each of the respective acquisitions represent the estimated values of each acquired company’s geographic presence in key markets, assembled workforce, synergies expected to be achieved from the combined operations of each of the acquired companies and MasTec, as well as the acquired company’s industry-specific project management expertise.
2025 Acquisitions. During the nine months ended September 30, 2025, MasTec acquired all of the equity interests of a telecommunications construction company that is included within the Company’s Communications segment, which acquisition was effective in July; and, effective in August, MasTec acquired all of the equity interests of a construction company specializing in roadway infrastructure, which is included within the Company’s Pipeline Infrastructure segment. Determination of the estimated fair values of net assets acquired and consideration transferred for these acquisitions, which have been accounted for as business combinations under ASC 805, was preliminary as of September 30, 2025; as a result, further adjustments to these estimates may occur. The Company expects to finalize the valuation and complete the purchase price consideration allocation no later than one year from the acquisition date.
Additionally, effective in July, MasTec acquired certain of the assets of an equipment company, which is accounted for as an asset acquisition under ASC 805 and included within the Company’s Pipeline Infrastructure segment.
The aggregate purchase price of the Company’s 2025 acquisitions was composed of approximately $19 million in cash, net of cash acquired.
2024 Acquisitions. During 2024, MasTec completed three acquisitions, which included 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, which acquisition is included within the Company’s Power Delivery segment, and was effective in July; the acquisition of certain operations of a heavy civil contractor specializing in transportation projects, which acquisition is included within the Company’s Clean Energy and Infrastructure segment and was effective in October; and effective in December, the acquisition of the equity interests of a company focused on pipeline infrastructure and heavy civil projects, which acquisition is included within the Company’s Pipeline Infrastructure segment. The Company expects these acquisitions will increase its service offerings and further advance its ability to meet increasing demand for data center infrastructure, in addition to expanding its heavy civil and pipeline infrastructure operations.
The aggregate purchase price of the Company’s 2024 acquisitions was composed of approximately $88 million in cash, net of cash acquired, and a five year earn-out liability valued at approximately $56 million with respect to one of such acquisitions. In connection with the acquisition within the Company’s Pipeline Infrastructure segment, MasTec acquired 60 % of the equity interest of the company in exchange for consideration transferred of cash and a 40 % equity interest in a MasTec Canadian subsidiary. Determination of the estimated fair values of net assets acquired and consideration transferred for one of these acquisitions, which have all been accounted for as business combinations under ASC 805, was preliminary as of September 30, 2025; as a result, further adjustments to these estimates may occur. The Company expects to finalize the valuation and complete the purchase price consideration allocation no later than one year from the acquisition date. As of September 30, 2025, the remaining potential undiscounted earn-out liabilities for the 2024 acquisitions was estimated to be between $25 million and $52 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 $45 million of the goodwill balance related to the 2024 acquisitions is expected to be tax deductible as of September 30, 2025.

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 the Company refers to as “Earn-outs,” that are contingent upon the acquired businesses achieving certain levels of earnings in the future. 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 10.5 % as of September 30, 2025, and probability-weighted projections of EBITDA. Significant changes in any of these assumptions could result in significantly higher or lower estimated 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 September 30, 2025, the range of potential undiscounted Earn-out liabilities was estimated to be between $41 million and $95 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. The following table, which may contain slight summation differences due to rounding, provides a reconciliation of changes in Earn-out liabilities measured at fair value for the periods indicated (in millions):

(a)Earn-out liabilities included within other current liabilities totaled approximately $46.7 million and $70.0 million as of September 30, 2025 and December 31, 2024, respectively.
(b)For the nine months ended September 30, 2025, fair value adjustments related primarily to decreases within the Company’s Power Delivery segment, which were partially offset by increases primarily within the Company’s Pipeline Infrastructure segment. For the nine months ended September 30, 2024, such adjustments related primarily to increases within the Company’s Clean Energy and Infrastructure and Pipeline Infrastructure segments, which were largely offset by decreases related to acquisitions within the Company’s Communications segment.
Equity Investments
The Company’s equity investments as of September 30, 2025 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 joint ventures; and (v) certain other equity investments.
As of September 30, 2025 and December 31, 2024, the aggregate carrying value of the Company’s equity investments, which are recorded within other long-term assets in the consolidated balance sheets, totaled approximately $328 million and $330 million, respectively. There were no
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. Cumulative undistributed earnings from the Waha JVs, which represents cumulative equity in earnings for the Waha JVs less distributions of earnings, totaled $144.5 million as of September 30, 2025. 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
14
method goodwill associated with capitalized investment costs, totaled approximately $288 million and $287 million as of September 30, 2025 and December 31, 2024, respectively. The table below reflects the investment activity of the Waha JVs for the periods indicated (in millions):

Other Investments. The Company has equity interests in certain other entities that are accounted for as equity method investments. The Company made no equity contributions to these other entities for the nine months ended September 30, 2025, and made equity contributions of approximately $0.2 million for the nine months ended September 30, 2024. The Company received distributions of approximately $0.5 million and $1.9 million from these entities for the nine months ended September 30, 2025 and 2024, respectively. 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 $0.9 million and $2.9 million for the three and nine months ended September 30, 2025, respectively, and totaled approximately $1.9 million and $4.2 million for the three and nine months ended September 30, 2024, respectively. As of September 30, 2025 and December 31, 2024, related amounts payable to these entities totaled approximately $0.4 million and $0.3 million, respectively. In addition, the Company advanced approximately $0.1 million to certain of these entities for the nine months ended September 30, 2024. As of September 30, 2025 and December 31, 2024, receivables related to these arrangements totaled approximately $4.0 million and $4.1 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 September 30, 2025, 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 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 September 30, 2025 and December 31, 2024, the carrying values of assets associated with the Company’s consolidated VIEs totaled approximately $172.0 million and $134.8 million, respectively, which amounts consisted primarily of accounts receivable, net of allowance and contract assets. The carrying values of liabilities associated with the Company’s consolidated VIEs totaled approximately $169.3 million and $132.8 million as of September 30, 2025 and December 31, 2024, respectively, which amounts consisted primarily of accounts payable. 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 $21 million and $23 million as of September 30, 2025 and December 31, 2024, 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 $29 million and $34 million as of September 30, 2025 and December 31, 2024, respectively.
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 periods indicated (in millions):

| Accounts receivable, net of allowance | $ | $ | |||||||||
| Retainage | $ | $ | |||||||||
| Unbilled receivables | |||||||||||
| Contract assets | $ | $ | |||||||||
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, which are included in contract assets, represent the estimated value of unbilled work for projects with performance obligations recognized over time. Unbilled receivables 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 nine months ended September 30, 2025, provisions for credit losses totaled a recovery of approximately $0.7 million and for the nine months ended September 30, 2024, provisions for credit losses totaled approximately $2.2 million, both of which included certain project-specific reserves. Impairment losses on contract assets were not material in either period.
15
Contract liabilities, which are generally classified within current liabilities on the Company’s consolidated balance sheets, consist primarily of deferred revenue and also include the amount of any accrued project losses. 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. Total contract liabilities, including accrued project losses, totaled approximately $730.3 million and $735.6 million as of September 30, 2025 and December 31, 2024, respectively, of which deferred revenue comprised approximately $721.1 million and $725.1 million, respectively.
As of September 30, 2025, the increase in contract assets was driven primarily by ordinary course project activity, including in connection with increased project volume primarily within the Company’s Communications segment. For the nine months ended September 30, 2025 and 2024, the Company recognized revenue of approximately $695.4 million and $390.3 million, respectively, related to amounts that were included in deferred revenue as of December 31, 2024 and December 31, 2023, 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. The Company has 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 nine months ended September 30, 2025 and 2024, the Company sold approximately $378 million and $338 million, respectively, of receivables under financing arrangements for which it continues to manage collections for the transferred receivable, and, as of September 30, 2025 and December 31, 2024, outstanding sold receivables related thereto totaled approximately $142 million and $84 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 $5.7 million and $5.3 million for the three months ended September 30, 2025 and 2024, respectively, and totaled approximately $17.6 million and $15.7 million for the nine months ended September 30, 2025 and 2024, respectively.

Senior Credit Facility
On June 26, 2025, the Company entered into an amended and restated five-year , senior unsecured credit facility (the “Credit Facility”) replacing the November 1, 2021 senior unsecured credit facility (“Existing Credit Agreement”) that would otherwise have terminated on November 1, 2026. The amendment, among other items, maintained revolving commitments of an aggregate amount of $1.9 billion, terminated the term loan under the Existing Credit Agreement, and extended the maturity of the senior secured credit facility from November 1, 2026 to June 26, 2030. The amendment also eliminated certain restrictions on the ability of the Company to make distributions or repurchase capital stock, the requirement of the Company to maintain a minimum consolidated interest coverage ratio and certain other negative covenants. All other material terms and conditions of the Credit Facility were substantially unchanged. The Credit Facility allows the Company to borrow up to an aggregate equivalent amount of $300 million in revolving advances in either Canadian dollars or Mexican pesos. The maximum amount available for letters of credit under the Credit Facility is $750 million, of which up to $250 million can be denominated in either Canadian dollars or Mexican pesos. The Credit Facility also provides for swing line loans of up to $125 million, and, subject to certain conditions, the Company has the option to increase revolving commitments as defined in the Credit Facility. As of both September 30, 2025 and December 31, 2024, the fair value of the Credit Facility, as estimated based on an income approach utilizing significant unobservable Level 3 inputs including discount rate assumptions, approximated its carrying value.
Outstanding revolving loans under the Credit Facility bear interest, at the Company’s option, at a rate equal to either (a) Term SOFR, TIIE, or Term CORRA, in each case as defined in the Credit Facility, plus a margin of 1.125 % to 1.625 %, or (b) Base Rate, as defined below, plus a margin of 0.125 % to 0.625 %. The Base Rate equals the highest of (i) the Federal Funds Rate, as defined in the Credit Facility, plus 0.50 %, (ii) Bank of America’s prime rate, and (iii) Term SOFR plus 1.00 %. Financial standby letters of credit and commercial letters of credit issued under the Credit Facility are subject to a letter of credit fee ranging from 1.125 % to 1.625 %, and performance standby letters of credit issued under such Credit Facility are subject to a letter of credit fee ranging from 0.3125 % to 0.6875 %. The Company must also pay a commitment fee to the lenders ranging from 0.150 % to 0.225 % on any unused availability under the Credit Facility. In each of the foregoing cases, the applicable margin or fee is based on the Company’s Consolidated Leverage Ratio and Debt Rating, each as defined in the Credit Facility, as of the most recent fiscal quarter.
As of September 30, 2025 and December 31, 2024, outstanding revolving loans, which included $42.4 million and $43.1 million, respectively, of borrowings denominated in Canadian dollars, accrued interest at weighted average rates of approximately 5.19 % and 4.97 % per annum, respectively. Letters of credit of approximately $20.8 million and $64.3 million were issued as of September 30, 2025 and December 31, 2024, respectively. As of both September 30, 2025 and December 31, 2024, letter of credit fees accrued at 0.5625 1.375
As of September 30, 2025 and December 31, 2024, availability for revolving loans totaled $1,736.8 million and $1,792.6 million, respectively, or up to $729.2 million and $585.7 million, respectively, for new letters of credit. Revolving loan borrowing capacity included $257.6 million and $256.9 million of availability in either Canadian dollars or Mexican pesos as of September 30, 2025 and December 31, 2024, respectively. The unused facility fee as of both September 30, 2025 and December 31, 2024 accrued at rates of 0.200

The Company has a separate credit facility, under which it may issue up to $50.0 million of performance standby letters of credit. As of September 30, 2025 and December 31, 2024, letters of credit issued under this facility totaled $33.4 million and $17.4 million, respectively, which accrued fees at 0.65 % and 0.75 % per annum, respectively.
Senior Notes
As of both September 30, 2025 and December 31, 2024, the gross carrying amount of the Company’s 4.500 % senior notes due August 15, 2028 (the “4.500 % Senior Notes”) totaled $600.0 598.0 million and $581.9 million, respectively. As of both September 30, 2025 and December 31, 2024, the gross carrying amount of the Company’s 5.900 % senior notes due June 15, 2029 (the “5.900 % Senior Notes”) totaled $550.0 575.7 million and $558.8 million, respectively. As of September 30, 2025 and December 31, 2024, the gross carrying amount of the Company’s 6.625 % senior notes due August 15, 2029 (the “6.625 % Senior Notes”) totaled $72.2 million and $71.6 million, respectively, and their estimated fair value approximated their carrying value for both respective periods. As of September 30, 2025 and December 31, 2024, the estimated fair values of the Company’s senior notes were determined based on an exit price approach using Level 2 inputs.
2025 Term Loan Facility
On June 26, 2025, the Company entered into a new $600 million senior unsecured term loan agreement (the “2025 Term Loan Facility”). The 2025 Term Loan Facility will mature on June 26, 2028, and the loans thereunder are not subject to amortization and are not guaranteed or secured by any assets of the Company or any of its subsidiaries. As of September 30, 2025, the Company had $600 million outstanding under the 2025 Term Loan Facility. The fair value of the 2025 Term Loan Facility as of September 30, 2025, as estimated based on an income approach utilizing significant unobservable Level 3 inputs including discount rate assumptions, approximated its carrying value. During the second quarter of 2025, using the net proceeds from the 2025 Term Loan Facility, together with available cash, the Company repaid the $328.1 million term loan under the Existing Credit Agreement and the remaining $277.5 million of the Company’s unsecured -year term loan (“the -Year Term Loan”) that would otherwise have matured on October 7, 2027.
Outstanding loans under the 2025 Term Loan Facility bear interest, at the Company’s option, at a rate equal to either (a) Term SOFR, as defined in the 2025 Term Loan Facility, plus a margin of 1.00 % to 1.50 %, or (b) a Base Rate, as defined below, plus a margin of up to 0.50 %. The Base Rate equals the highest of (i) the Federal Funds Rate, as defined in the 2025 Term Loan Facility, plus 0.50 %, (ii) Bank of America’s prime rate, and (iii) Term SOFR plus 1.00 %. In each of the foregoing cases, the applicable margin is based on the Company’s Consolidated Leverage Ratio and
17
Debt Rating, each as defined in the 2025 Term Loan Facility, as of the most recent fiscal quarter. As of September 30, 2025, the 2025 Term Loan Facility accrued interest at a rate of 5.416 %.
-Year Term Loan Facility
As described above, during the second quarter of 2025, the Company used a portion of the net proceeds from the 2025 Term Loan Facility, together with available cash, to repay the remaining $277.5 million of the -Year Term Loan that would otherwise have matured on October 7, 2027.
Debt Covenants
The Company’s Credit Facility and 2025 Term Loan Facility contain affirmative and negative covenants that, among other things, limit the Company’s ability to engage in certain activities, including, but not limited to, acquisitions, mergers and consolidations, debt incurrence, investments, asset sales and lien incurrence. In addition, the Credit Facility and 2025 Term Loan Facility provide for customary events of default and carries cross-default provisions with the Company’s other significant debt instruments, including the Company’s indemnity agreement with its surety provider, as well as customary remedies, including the acceleration of repayment of outstanding amounts and other remedies. The Credit Facility and 2025 Term Loan Facility require the Company to maintain a maximum Consolidated Leverage Ratio, as defined in the Credit Facility and 2025 Term Loan Facility, respectively, of not more than 3.50 :1.00 as of the end of any fiscal quarter (except that, subject to certain conditions, if a permitted acquisition or series of permitted acquisitions having consideration exceeding $200 million occurs, such ratio is increased to 4.00 :1.00 for the fiscal quarter in which the acquisition is completed and the four subsequent fiscal quarters). For purposes of calculating the Consolidated Leverage Ratio, funded indebtedness excludes undrawn standby performance letters of credit included in the calculation of Consolidated Funded Indebtedness, as defined in the Credit Facility and 2025 Term Loan Facility, respectively.
MasTec was in compliance with the provisions and covenants of its outstanding debt instruments as of both September 30, 2025 and December 31, 2024.
Additional Information
In connection with the amended and restated Credit Facility and the 2025 Term Loan Facility, deferred financing costs of $4.2 million and $1.2 million, respectively, were incurred during the second quarter of 2025 and are being amortized over the respective terms of those instruments. Such amortization is included in interest expense, net in the consolidated statements of operations.
As of September 30, 2025 and December 31, 2024, accrued interest payable, which is recorded within other accrued expenses in the consolidated balance sheets, totaled $16.4 million and $20.8 million, respectively.

Note 9 – 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 months ended September 30, 2025 and 2024, the Company’s consolidated effective tax rates were 21.3 % and 23.0 %, respectively, and for the nine months ended September 30, 2025 and 2024 were 21.2 % and 25.8 %, respectively. The Company’s effective tax rate for the nine months ended September 30, 2025 included income tax benefits primarily due to the reversal of uncertain tax position liabilities related to a state audit and the release of valuation allowances on certain deferred tax assets that were no longer necessary, offset, in part, by an increase in income tax expense due to higher pre-tax income. For the nine months ended September 30, 2024, the Company’s effective tax rate included the effect of a lower state income tax rate partially offset by a higher percentage of non-deductible expenses relative to pre-tax income.
On July 4, 2025, new tax legislation was signed into law, known as the One Big Beautiful Bill Act (the “OBBBA”), which makes permanent many of the tax provisions enacted in 2017 as part of the Tax Cuts and Jobs Act that were set to expire at the end of 2025. In addition, the OBBBA makes changes to certain U.S. corporate tax provisions, but many are generally not effective until 2026. The Company has undertaken efforts to reasonably estimate the impact of the provisions of the new law and expects that there will be no material impacts to the consolidated financial statements. The Company will continue to evaluate the full impact of these legislative changes as more guidance becomes available.
Note 10 – 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) Pipeline Infrastructure and (5) Other. The reportable segments comprise the structure used by the Company’s Chief Executive Officer who is determined to be the Chief Operating Decision Maker (“CODM”) to make key operating decisions and assess performance. This structure is generally focused on broad end-user markets for the Company’s labor-based construction services. All five 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, wireless integration and optimization and install-to-the-home services, 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 services, including roads, bridges and rail; and environmental remediation services. The Power Delivery segment primarily serves the energy, utility and data center infrastructure industries through the engineering, construction and maintenance of power transmission and distribution infrastructure, including electrical and gas lines, power reserve and battery infrastructure, and distribution network systems, substations and grid modernization; emergency restoration services following natural disasters and accidents; and environmental planning and compliance services. The Pipeline Infrastructure 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, including the repair of pipeline infrastructure and facilitating their safe use throughout their lifecycle, 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.
In the first quarter of 2025, the Company made changes to its Communications segment and Power Delivery segment structures to more closely align with the segments’ end markets and to better correspond with the operational management reporting structures of both segments. These changes included moving a component with utility operations previously reported in the Communications segment to the Power Delivery segment. These changes did not impact the Company’s consolidated financial statements, but did impact its reportable segments, including historical financial information. The segment data presented below have been recast for the historical periods to reflect these segment changes.
Earnings before interest, taxes, depreciation and amortization (“EBITDA”) is the measure of profitability used by the Company’s CODM to manage its segments and for segment reporting purposes. The Company uses EBITDA to evaluate its performance, both internally and as compared with its peers, because it excludes certain items that may not be indicative of the Company’s core operating results for its reportable
20
segments, as well as items that can vary widely across different industries or among companies within the same industry. Segment EBITDA is used to allocate resources, such as employees, financial and capital resources, for each segment and management monitors segment results compared to prior period, forecasted results and the annual plan. 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, which may contain slight summation differences due to rounding, reflect certain financial data for each reportable segment and have been recast as described above.

Note 11 – 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 2024 Form 10-K for additional information regarding the acquired legacy solar matter, with respect to which, in January 2025, the parties agreed to a negotiated settlement and mutual releases in exchange for the payment to the plaintiffs by Infrastructure and Energy Alternatives, Inc. (“IEA”) and its subsidiary, IEA Constructors, LLC, of an immaterial amount of cash. 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 12 – 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 VIEs. In addition, from time to time, certain customers require the Company to post letters of credit to ensure payment of subcontractors and vendors, and guarantee performance under contracts. Such letters of credit are generally issued by a bank or similar financial institution. The letter of credit commits the issuer to pay specified amounts to the holder of the letter of credit 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 September 30, 2025 and December 31, 2024, there were $54.2 million and $81.7 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 September 30, 2025 or December 31, 2024.
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 September 30, 2025 and December 31, 2024, outstanding performance and payment bonds approximated $9.4 billion and $7.6 billion, respectively, and estimated costs to complete projects secured by these bonds totaled $3.2 billion and $2.2 billion, respectively. Included in these balances as of September 30, 2025 and December 31, 2024 are $1.3 billion and $838.7 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 seven 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 September 30, 2025, the Company was not aware of material claims against it in connection with these arrangements. Included in the Company’s cash balances as of September 30, 2025 and December 31, 2024 are amounts held by entities that are proportionately consolidated totaling $32.3 million and $46.7 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 12 – 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
23
reimburses claims up to the applicable insurance limits. Captive insurance-related cash balances totaled approximately $3.3 million and $2.2 million as of September 30, 2025 and December 31, 2024, respectively, which amounts are generally not available for use in the Company’s other operations.
As of September 30, 2025 and December 31, 2024, MasTec’s estimated gross liability for unpaid claims and associated expenses, including incurred but not reported losses related to these policies, totaled $295.1 million and $251.0 million, respectively, of which $218.2 million and $184.1 million was reflected within other long-term liabilities, with the remainder reflected within other accrued expenses, in the consolidated balance sheets as of the respective periods. Related insurance recoveries/receivables totaled $26.3 million and $24.4 million as of September 30, 2025 and December 31, 2024, respectively, of which $23.3 million and $21.4 million was reflected within other long-term assets, with the remainder reflected within other current assets, in the consolidated balance sheets as of 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 $2.2 million and $4.7 million as of September 30, 2025 and December 31, 2024, 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 $7.4 million and $8.7 million as of September 30, 2025 and December 31, 2024, respectively. Outstanding surety bonds related to self-insurance programs amounted to $206.6 million and $196.3 million as of September 30, 2025 and December 31, 2024, respectively.
Collective Bargaining Agreements and Multiemployer Plans. In connection with the IEA acquisition, the Company assumed a multiemployer pension plan withdrawal liability (the “IEA withdrawal liability”), under which IEA was obligated to make monthly payments of approximately $10,000 . In January 2025, the Company settled its IEA withdrawal liability by issuing a lump-sum payment for the remaining obligation of $1.3 million. See Note 14 – Commitments and Contingencies contained within the Company’s audited consolidated financial statements filed with its 2024 Form 10-K for additional information regarding the Company’s multiemployer pension plans.
Indemnities. The Company generally indemnifies its customers for the services it provides under its contracts, as well as other specified liabilities, which may subject the Company to indemnity claims, liabilities and related litigation. As of September 30, 2025 and December 31, 2024, the Company had accrued project close-out liabilities of approximately $5 million and $20 million, respectively. 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 1,630 customers for the nine months ended September 30, 2025. As of both September 30, 2025 and December 31, 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. The Company derived approximately 35 % and 34 % of its revenue from its top ten customers for the three months ended September 30, 2025 and 2024, respectively, and derived approximately 34 % and 37 % of such revenue for the nine months ended September 30, 2025 and 2024, 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 September 30, 2025 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 2024 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 and anticipate the remainder of 2025 to continue to be a dynamic macroeconomic environment, with continuing levels of cost inflation due, in part, to trade actions discussed below, and potential market volatility, any or all of which could adversely affect our costs and customer demand.
As disclosed within our “Risk Factors” in our 2024 Form 10-K as updated by Item 1A, “Risk Factors” of our Quarterly Reports on Form 10-Q, we are subject to risks related to, among other factors, trade actions, including tariffs, that may have significant effects on macroeconomic conditions. During the nine months ended September 30, 2025, the U.S. government announced or imposed a variety of tariff or other trade actions, in response to which many countries have announced retaliatory trade actions, including tariffs on U.S. exports or bans by foreign countries on certain of their exports. These actions have increased the cost of importing certain construction materials into the U.S., including steel, concrete, copper and solar panels, and have caused disruption and uncertainty to both international trade and supply chains.
While these trade actions have not had a material impact on the results of our operations to date, we are monitoring and evaluating any potential impacts from the imposition of tariffs and other trade measures, particularly as they may affect our customers’ capital spending plans, supply chains and operational costs, and are considering ways in which we or our customers may mitigate their related impacts. However, the tariff environment remains dynamic and we cannot predict with certainty the effect future changes in global trade policy and tariffs will have on our customers and/or on demand for our services in future periods.
Further, on July 4, 2025, the One Big Beautiful Bill Act (the “OBBBA”) was enacted in the United States increasing federal support for oil and gas production while reducing support for renewable energy and infrastructure. Notably, the OBBBA accelerates the phaseout of certain clean energy tax credits established under the Inflation Reduction Act, including the clean electricity investment and clean energy production credits for solar and wind projects, which may reduce longer term demand for such projects. Under the new provisions, these credits will no longer be available for projects placed in service after December 31, 2027, unless construction begins on or before July 4, 2026, pursuant to a grandfathering rule. Projects that qualify under this rule must still meet continuity requirements to remain eligible. At the same time, the OBBBA contains other provisions to incentivize oil and gas development as well as to support energy infrastructure such as carbon capture and energy storage. The OBBBA, along with other evolving trade and immigration policies, may have both positive and negative effects on our business, including, but not limited to, shifts in the timing, type and scope of customer projects, fluctuations in demand for our services, and changes in capital and labor costs, including availability.
We will continue to monitor the market and economic conditions. The extent to which general economic, market, political 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 2024 Form 10-K.

Business Overview
We are a leading North American infrastructure engineering and construction company focused primarily on engineering, building, installation, maintenance and upgrade of communications, energy and utility and other infrastructure, such as: wireless, wireline/fiber; power delivery infrastructure, including transmission, distribution, grid hardening and modernization, 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 over 95 years. For the twelve months ended September 30, 2025, we had an average of approximately 34,000 employees and 790 locations, and as of September 30, 2025, we had approximately 38,000 employees and 810 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 integrated, solutions-based 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) Pipeline Infrastructure and (5) Other. This structure is generally focused on broad end-user markets for our labor-based construction services.
In the first quarter of 2025, we made changes to our Communications and Power Delivery segment structure to more closely align with our segments’ end markets and to better correspond with the operational management reporting structure of both segments. These changes included moving a component with utility operations previously reported in our Communications segment to our Power Delivery segment. These changes did not impact our consolidated financial statements, but did impact our reportable segments, including historical financial information. See Note 10 – Segments and Related Information and Note 11 – 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 23% of our estimated September 30, 2025 backlog in 2025. The following table presents 18-month estimated backlog by reportable segment as of the periods indicated:
| Reportable Segment (in millions): | September 30, 2025 | June 30, 2025 | September 30, 2024 (a) | ||||||||||||||
Communications | $ | 5,055 | $ | 5,008 | $ | 4,416 | |||||||||||
Clean Energy and Infrastructure | 5,026 | 4,922 | 4,141 | ||||||||||||||

| Estimated 18-month backlog | $ | 16,780 | $ | 16,452 | $ | 13,858 | |||||||||||
(a) Recast to reflect first quarter of 2025 segment changes. See Note 10 – Segments and Related Information in the notes to the consolidated financial statements, which is incorporated by reference, for additional information.
As of September 30, 2025, 48% 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 September 30, 2025, total 18-month backlog differed from the amount of our remaining performance obligations due primarily to the inclusion of $8.3 billion of estimated future revenue under master service and other service agreements within our backlog estimates, as described above, and the exclusion of approximately $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 2025 differs from the amount of remaining performance obligations expected to be recognized for the same period due primarily to the inclusion of
27
approximately $0.9 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, including the potential effects of the factors discussed above in “General Economic, Market and Regulatory Conditions,” 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 2024 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 2024 Form 10-K.
Critical Accounting Policies and 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 2024 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 changes to our Communications segment and Power Delivery segment structures in the first quarter of 2025, management performed a quantitative assessment of the goodwill associated with each of the impacted reporting units within the Communications and Power Delivery operating segments, respectively. For additional details of the changes 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.
Other than the update to the reporting unit structure of our Communications and Power Delivery operating segments during the first quarter of 2025, as described above, there were no material changes in our critical accounting estimates or policies during the nine months ended September 30, 2025.
Results of Operations
Comparison of Consolidated Results
The following tables, which may contain slight summation differences due to rounding, reflect 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, as appropriate, which are described in the comparison of results section below. Unless otherwise stated, comparisons are for the periods ended September 30, 2025 and 2024. Historical financial information for our reportable segments has been recast to conform with the changes described in Note 10 – Segments and Related Information in the notes to the consolidated financial statements, which is incorporated by reference.

Revenue. On a consolidated basis, revenue increased by $715 million, or 22%, driven by our segment results as follows: revenue increased in our Communications segment by approximately $227 million, or 33%, in our Clean Energy and Infrastructure segment by approximately $226 million, or 20%, in our Power Delivery segment by approximately $160 million, or 17%, and in our Pipeline Infrastructure segment by approximately $100 million, or 20%. See below for details of revenue by segment.
Costs of revenue, excluding depreciation and amortization. Higher levels of revenue contributed an increase of $613 million in costs of revenue, excluding depreciation and amortization, and reduced productivity contributed an increase of approximately $27 million. Costs of revenue, excluding depreciation and amortization, as a percentage of revenue increased by approximately 70 basis points to 86.4% of revenue for the three months ended September 30, 2025 from 85.8% of revenue for the same period in 2024. The basis point increase was due to a combination of project mix and reduced project efficiencies, primarily within our Pipeline Infrastructure segment, offset, in part, by improved productivity and efficiencies within our Clean Energy and Infrastructure segment.
Depreciation. As a percentage of revenue, depreciation decreased by approximately 70 basis points, due primarily to a net reduction related to a change in the depreciable lives of certain machinery and equipment to better align the respective assets’ lives with their expected useful lives, and, to a lesser extent, asset sales, offset, in part, by higher capital expenditures to support operational growth and the replacement of older machinery and equipment.
Amortization of intangible assets. The decrease in amortization of intangible assets was 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 20 basis points as compared with the same period in 2024 due, in part, to higher levels of revenue.
General and administrative expenses. The increase in general and administrative expenses was primarily due to an increase in compensation expense and professional fees, as well as a decrease in gains on sales of assets, net. Overall, general and administrative expenses decreased by approximately 60 basis points as a percentage of revenue for the three months ended September 30, 2025 as compared with the same period in 2024 due to higher levels of revenue.
Interest expense, net. The decrease in interest expense, net, resulted primarily from lower average balances and, to a lesser extent, lower average interest rates on our variable rate debt, which accounted for a reduction in interest expense of approximately $3 million, offset, in part, by an increase in interest expense from finance lease activity.
Equity in earnings of unconsolidated affiliates, net. For both the three months ended September 30, 2025 and 2024, equity in earnings from unconsolidated affiliates, net, totaled approximately $7 million, and related primarily to our investments in the Waha JVs.
Other expense, net. For the three months ended September 30, 2025, other expense, net, included approximately $2 million of expense, net from the changes in the fair value of additional contingent payments to former owners of an acquired business. For the three months ended September 30, 2024, other expense, net, included approximately $2 million of expense, net, from changes to estimated Earn-out accruals and approximately $2 million of expense, net, from the changes in the fair value of additional contingent payments to former owners of an acquired business, offset, in part, by other miscellaneous income, net, including amounts from legal and other settlements.
Provision for income taxes. For the three months ended September 30, 2025, our effective tax rate was 21.3% as compared with 23.0% for the same period in 2024. Our effective tax rate for the three months ended September 30, 2025, included income tax benefits primarily due to the reversal of uncertain tax position liabilities related to a state audit and the release of valuation allowances on certain deferred tax assets that were no longer necessary, offset, in part, by an increase in income tax expense due to higher pre-tax income, whereas for the three months ended September 30, 2024, our effective tax rate included the effect of a lower state income tax rate partially offset by a higher percentage of non-deductible expenses relative to pre-tax income.
29
Net income attributable to non-controlling interests. Net income attributable to non-controlling interests was $6 million for the three months ended September 30, 2025, as compared with $10 million for the same period in 2024. The decrease was primarily attributable to the decrease in activity of certain entities within the Communications segment with minority interest holders.

NM - Percentage is not meaningful
Revenue. On a consolidated basis, revenue increased by $1,459 million, or 16%, driven by our segment results as follows: revenue increased in our Communications segment by approximately $648 million, or 36%, in our Clean Energy and Infrastructure segment by approximately $577 million, or 20%, and in our Power Delivery segment by approximately $439 million, or 17%, and decreased in our Pipeline Infrastructure segment by approximately $210 million, or 12%. See below for details of revenue by segment.
Costs of revenue, excluding depreciation and amortization. Higher levels of revenue contributed an increase of $1,264 million in costs of revenue, excluding depreciation and amortization, and reduced productivity contributed an increase of approximately $102 million. Costs of revenue, excluding depreciation and amortization, as a percentage of revenue increased by approximately 100 basis points to 87.6% of revenue for the nine months ended September 30, 2025 from 86.6% of revenue for the same period in 2024. The basis point increase was due to a combination of project mix and reduced project efficiencies, primarily within our Pipeline Infrastructure and Power Delivery segments, offset, in part, by improved productivity and efficiencies within our Clean Energy and Infrastructure segment.
Depreciation. As a percentage of revenue, depreciation decreased by approximately 120 basis points, due primarily to a net reduction related to a change in the depreciable lives of certain machinery and equipment to better align the respective assets’ lives with their expected useful lives, and, to a lesser extent, asset sales, offset, in part, by higher capital expenditures to support operational growth and the replacement of older machinery and equipment.
Amortization of intangible assets. The decrease in amortization of intangible assets was 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 20 basis points as compared with the same period in 2024 due, in part, to higher levels of revenue.
General and administrative expenses. The increase in general and administrative expenses was primarily due to an increase in professional fees, the effects of timing of ordinary course legal matters, and a decrease in gains on sales of assets, net, offset, in part, by a decrease in the provision for credit losses. Overall, general and administrative expenses decreased by approximately 60 basis points as a percentage of revenue for the nine months ended September 30, 2025 as compared with the same period in 2024 due to higher levels of revenue.
Interest expense, net. The decrease in interest expense, net, resulted primarily from lower average balances and, to a lesser extent, lower average interest rates on our variable rate debt, which accounted for a reduction of approximately $35 million, offset, in part, by an increase in interest expense from our senior notes due to higher average balances, including from the June 2024 issuance of our 5.900% Senior Notes, and, to a lesser extent, from finance leases and accounts receivable financing arrangements due to higher levels of activity.
Equity in earnings of unconsolidated affiliates, net. For the nine months ended September 30, 2025 and 2024, equity in earnings from unconsolidated affiliates, net, totaled approximately $24 million and $22 million, respectively, and related primarily to our investments in the Waha JVs.
Loss on extinguishment of debt. We incurred a loss on debt extinguishment of approximately $11 million for the nine months ended September 30, 2024 in connection with the second quarter 2024 repayment of our 6.625% IEA Senior Notes and Three-Year Term Loan Facility.
30
Other (income) expense, net. For the nine months ended September 30, 2025, other income, net, included approximately $3 million of income, net, from changes to estimated Earn-out accruals, and approximately $2 million of other miscellaneous income, net, offset, in part, by approximately $4 million of expense, net from the changes in the fair value of additional contingent payments to former owners of an acquired business. For the nine months ended September 30, 2024, other expense, net, included approximately $3 million of expense, net, from the changes in the fair value of additional contingent payments to former owners of an acquired business and approximately $10 million of asset impairment and other valuation adjustments related to certain fixed assets, offset, in part, by approximately $6 million of other miscellaneous income, net, including amounts from legal and other settlements.
Provision for income taxes. For the nine months ended September 30, 2025, our effective tax rate was 21.2% as compared with 25.8% for the same period in 2024. Our effective tax rate for the nine months ended September 30, 2025, included income tax benefits primarily due to the reversal of uncertain tax position liabilities related to a state audit and the release of valuation allowances on certain deferred tax assets that were no longer necessary, offset, in part, by an increase in income tax expense due to higher pre-tax income, whereas for the nine months ended September 30, 2024, our effective tax rate included the effect of a lower state income tax rate partially offset by a higher percentage of non-deductible expenses relative to pre-tax income.
Net income attributable to non-controlling interests. Net income attributable to non-controlling interests was $13 million for the nine months ended September 30, 2025, as compared with $27 million for the same period in 2024. The decrease was primarily attributable to the decrease in activity of certain entities within the Pipeline Infrastructure and Communications segments with minority interest holders.
Analysis of Revenue and EBITDA by Segment
We review our operating results by reportable segment. See Note 10 – Segments and Related Information in the notes to the consolidated financial statements, which is incorporated by reference. Our reportable segments are: (1) Communications; (2) Clean Energy and Infrastructure; (3) Power Delivery; (4) Pipeline Infrastructure and (5) Other. Management’s review of segment results includes analyses of trends in revenue, EBITDA and EBITDA margin. EBITDA for segment reporting purposes is calculated consistently with our consolidated EBITDA calculation. EBITDA margin is calculated by dividing EBITDA by revenue for the same period. See the discussion of our non-U.S. GAAP financial measures, including certain adjusted non-U.S. GAAP measures, as described below, following the comparison of results discussion. Historical financial information for our reportable segments has been recast to conform with the changes described in Note 10 – Segments and Related Information in the notes to the consolidated financial statements, which is incorporated by reference. The following tables, which may contain slight summation differences due to rounding, present revenue, EBITDA and EBITDA margin by segment for the periods indicated (dollar amounts in millions).

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”), adjusted net income attributable to MasTec, Inc. (“Adjusted Net Income Attributable to MasTec, Inc.”) 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; loss on extinguishment of debt and changes in fair value of acquisition-related contingent items, as more fully described below; and, for Adjusted Net Income, Adjusted Net Income Attributable to MasTec, Inc. 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, Adjusted Net Income Attributable to MasTec, Inc. 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. We also exclude intangible asset amortization and the effects of changes in fair value of acquisition-related contingent items from our non-U.S. GAAP financial measures due to their non-operational nature and inherent volatility, as activity, including from acquisitions, varies from period to period. 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. Acquisition-related contingent items consist of (i) changes in fair value of acquisition-related contingent consideration, which is composed of earn-outs, that are contingent upon the achievement of reaching certain post-acquisition levels of earnings and (ii) changes in fair value of additional payments in connection with the 2021 acquisition of Henkels & McCoy Holdings, Inc. based on the fluctuation of our share price and are contingent upon the post-acquisition collections of certain receivables. We believe that this presentation is common practice within our industry and improves comparability of our results with those of our peers.
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
33
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 months ended September 30, 2025 and 2024, our consolidated tax amounts were expenses, with effective tax rates, as reported, of 21.3% and 23.0%, respectively, and as adjusted, were expenses, with effective tax rates of 21.6% and 22.2%, respectively. For the nine months ended September 30, 2025 and 2024, our consolidated tax amounts were expenses, with effective tax rates, as reported, of 21.2% and 25.8%, respectively, and as adjusted, were expenses, with effective tax rates of 21.7% and 24.0%, respectively. See Note 9 – Income Taxes in the notes to the consolidated financial statements, which is incorporated by reference, for additional information regarding our consolidated tax amounts and effective tax rates for the respective periods.
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.
Capital Expenditures. For the nine months ended September 30, 2025, we spent approximately $180 million on capital expenditures, or $137 million, net of asset disposals, and incurred approximately $188 million of equipment purchases under finance leases and other financing arrangements. We estimate that we will spend approximately $235 million on capital expenditures, or approximately $175 million, net of asset disposals, in 2025, and we expect to incur approximately $215 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
35
acquired businesses, which we also refer to as “Earn-out” payments. From time to time, our acquisitions may contain certain additional payments if specified conditions are met. 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 September 30, 2025 was approximately $85 million. Of this amount, approximately $41 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 nine months ended September 30, 2025 and 2024, payments related to our Earn-out liabilities totaled $25 million and $26 million, respectively.
Income Taxes. For the nine months ended September 30, 2025 and 2024, tax payments, net of tax refunds totaled approximately $37 million and $45 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 September 30, 2025, 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 $3.7 billion as of September 30, 2025 as compared with $2.9 billion as of December 31, 2024, due primarily to higher levels of revenue, as well as the timing of project billings and collections. See below for discussion of our days sales outstanding, net of contract liabilities, which we refer to as days sales outstanding, or “DSO.”
Our payment billing terms are generally net 30 days, and some of our contracts allow our customers to retain a portion of the contract amount, generally from 5% to 10% of billings, until the job is completed, 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 the mobilization of assets and/or crew to project sites and/or for materials purchases up to specified amounts. Vendor terms are generally 30 to 45 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 September 30, 2025, we had approximately $1,071 million in working capital, defined as current assets less current liabilities, as compared with $653 million as of December 31, 2024, an increase of approximately $418 million. Cash and cash equivalents totaled approximately $231 million and $400 million as of September 30, 2025 and December 31, 2024, respectively, for a decrease of $168 million. See discussion below for further detail regarding our cash flows and related activity.
Sources and uses of cash are summarized below (in millions):
Nine Months Ended September 30, | |||||||||||
| 2025 | 2024 | ||||||||||
| Net cash provided by operating activities | $ | 173.0 | $ | 649.9 | |||||||
| Net cash used in investing activities | $ | (155.3) | $ | (80.8) | |||||||
| Net cash used in financing activities | $ | (187.0) | $ | (916.5) | |||||||
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, net, 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 was $173 million as compared to $650 million for the nine months ended September 30, 2025 and 2024, respectively, for a decrease in net cash provided by operating activities of approximately $477 million. The decrease was due primarily to changes in working capital compared with the prior period, including from the negative effect of timing-related changes in accounts receivable, net,
36
primarily driven by higher levels of revenue and an increase in DSO, and contract liabilities, offset, in part, by the positive effect of timing-related changes in accounts payable and accrued expenses, and an increase in net income as compared with the prior period.
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. A decrease in DSO has a favorable impact on cash flow from operating activities, while an increase in DSO has a negative impact on cash flow from operating activities. Our DSO was 69 as of September 30, 2025 as compared with DSO of 60 as of December 31, 2024. 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 to a lesser extent the effect of working capital initiatives, including certain accounts receivable financing arrangements. The increase in DSO as of September 30, 2025 as compared with December 31, 2024 was due to timing of ordinary course billing and collection activities. Other than certain 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 was $155 million as compared to $81 million for the nine months ended September 30, 2025 and 2024, respectively, for an increase of $75 million. Capital expenditures totaled $180 million, or $137 million, net of asset disposals, for the nine months ended September 30, 2025, as compared with $101 million, or $52 million, net of asset disposals, for the same period in 2024, for an increase in cash used in investing activities of approximately $86 million, primarily to support operational growth and the replacement of older machinery and equipment.
Financing Activities. Net cash used in financing activities for the nine months ended September 30, 2025 was $187 million, as compared to $917 million for the same period in 2024, for a decrease in cash used in financing activities of approximately $729 million. For the nine months ended September 30, 2025, we had $81 million of borrowings, net of repayments, under our credit facility and term loans, as compared with $1,046 million of repayments, net of borrowings, for the same period in 2024, for a decrease in cash used in financing activities of $1,126 million. The decrease in cash used in financing activities from above was offset, in part, by an increase in net proceeds of Senior Notes in the nine months ended September 30, 2024 of $326 million, consisting of $550 million in proceeds from our 5.900% Senior Notes and $224 million of repayments made on our 6.625% Senior Notes. Share repurchases totaled approximately $77 million for the nine months ended September 30, 2025, whereas there were no share repurchases for the same period in 2024. Additionally, payments of acquisition-related contingent consideration included within financing activities decreased by $7 million. Total payments of acquisition-related contingent consideration, including payments in excess of acquisition-date liabilities, which are classified within operating activities, totaled $25 million for the nine months ended September 30, 2025 as compared with $26 million for the same period in 2024.
Senior Credit Facility
On June 26, 2025, we amended and restated our senior unsecured credit facility (the “Credit Facility”), which matures on June 26, 2030 and is composed of $1.9 billion of revolving commitments. As of September 30, 2025, aggregate outstanding revolving borrowings totaled approximately $142 million and availability for revolving loans totaled $1,737 million. 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 6 – Debt in the notes to the consolidated financial statements, which is incorporated by reference.
Senior Notes
Our senior notes include $600 million aggregate principal amount of 4.500% senior unsecured notes due August 15, 2028 (the “4.500% Senior Notes”), $550 million aggregate principal amount of 5.900% senior unsecured notes due June 15, 2029 (the “5.900% Senior Notes”) and $75 million aggregate principal amount of 6.625% senior unsecured notes due August 15, 2029 (the “6.625% Senior Notes”). Our 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 2024 Form 10-K.
2025 Term Loan Facility
On June 26, 2025, we entered into a new $600 million senior unsecured term loan agreement (the “2025 Term Loan Facility”) which matures on June 26, 2028 and the loans thereunder are not subject to amortization. In the second quarter of 2025, we used the proceeds from the 2025 Term Loan Facility, together with available cash, to repay the $328.1 million term loan under our Existing Credit Agreement and the remaining $277.5 million of our Five-Year Term Loan that would otherwise have matured on October 7, 2027. The 2025 Term Loan Facility is subject to certain provisions and covenants, as more fully described in Note 6 – Debt in the notes to the consolidated financial statements, which is incorporated by reference.
Debt Covenants
We were in compliance with the provisions and covenants contained in our outstanding debt instruments as of September 30, 2025, and we expect to be in compliance with these provisions and covenants for the next twelve months.
37
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 2024 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 4 – Fair Value of Financial Instruments, Note 11 – Commitments and Contingencies and Note 12 – 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 2024 Form 10-K for additional information related to our off-balance sheet arrangements.
Impact of Inflation
The primary inflationary factors affecting our operations are labor, fuel and material costs. In times of low unemployment, our labor costs may increase due to shortages in the supply of skilled labor and increases in compensation rates generally. Immigration actions may also affect the availability of labor. Although most project materials are provided by our customers, increases in the cost of materials could negatively affect the economic viability of their projects, and accordingly, demand for our services. Material and commodity prices are subject to volatility due to events outside of our control, such as tariff and trade actions, which have contributed to recent market fluctuations. Inflation rates in the United States increased significantly over the past several years and, while recent inflationary pressure has somewhat abated, the high-cost environment has remained intact and we expect it to continue for the remainder of 2025 due, in part, to trade actions described above under “General Economic, Market and Regulatory Conditions.” Elevated levels of labor, fuel and material costs have in the past and could in the future negatively affect our project margins to the extent that we are unable to pass such cost increases along to our customers. In addition, there is uncertainty of what effect, if any, trade tariffs will have on inflation in future periods. Such 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, type and scope of project work.
While inflationary factors have not had a material impact on our business operations, operating results and/or financial condition, we closely monitor such factors and any potential effects they may have on such items. While the impact of these factors cannot be fully eliminated, we take proactive steps to mitigate their effects. 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 2024 Form 10-K.
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Risk
Our interest expense is affected by the prevailing interest rate environment. While the cost of our variable debt fluctuates with changes in market interest rates, the interest on our fixed rate debt is unaffected by such changes. We manage interest rate risk by maintaining a mix of fixed and variable rate debt obligations. As of September 30, 2025, our variable interest rate debt was primarily related to our Credit Facility and 2025 Term Loan Facility. As of September 30, 2025, we had approximately $142 million of revolving loans outstanding under our Credit Facility with a weighted average interest rate of 5.19% and a $600 million 2025 Term Loan Facility with a weighted average interest rate of 5.42%.
An additional 100 basis point increase in the applicable interest rates under our Credit Facility and 2025 Term Loan Facility would have increased our interest expense by approximately $7 million for the nine months ended September 30, 2025.
As of September 30, 2025, our fixed interest rate debt primarily included $600 million aggregate principal amount of 4.500% Senior Notes, $550 million aggregate principal amount of 5.900% Senior Notes, $75 million aggregate principal amount of 6.625% Senior Notes and $343 million of finance lease obligations, which accrued interest at a weighted average interest rate of approximately 4.9%. None of this debt subjects us to financial statement risk associated with changes in interest rates, 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 nine months ended September 30, 2025. 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 nine months ended September 30, 2025. 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 nine months ended September 30, 2025, foreign currency translation gains, net, totaled approximately $3 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 September 30, 2025. We may enter into foreign currency derivative contracts in the future to manage such exposure.
38
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 September 30, 2025.
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 September 30, 2025 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 11 – 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 2024 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
Our business is subject to a variety of risks and uncertainties. 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 2024 Form 10-K, as updated by our Quarterly Reports on Form 10-Q and other filings we make with the SEC.
