Fair Value Disclosures [Abstract]  
Fair Value of Financial Instruments 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 flow 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, such as projected financial results, and are evaluated on an ongoing basis. Key assumptions include the discount rate, which as of September 30, 2026 ranged from 11.0% to 23.8% with a weighted average rate of 14.1%, and probability-weighted projections of revenue, operating costs and cash flows. 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, 2026, the range of potential undiscounted Earn-out liabilities was estimated to be between $18 million and $383 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):

(b)For the nine months ended September 30, 2026, fair value adjustments related primarily to increases within the Power Delivery segment. For the nine months ended September 30, 2025, fair value adjustments related primarily to decreases within the Power Delivery segment, which were partially offset by increases primarily within the Pipeline Infrastructure segment.
Equity Investments
The Company’s equity investments as of September 30, 2026 include the Company’s: (i) 33% equity interests in Trans-Pecos Pipeline, LLC and Comanche Trail Pipeline, LLC, collectively “Waha JVs”; (ii) 33% to 50% equity interests in equity investments specializing in electrical contracting that were included in the net assets acquired as part of the Superior acquisition and are operationally integral to the Company’s business (the “Integral Investments”); (iii) interests in certain proportionately consolidated non-controlled joint ventures; and (iv) certain other equity investments. As of September 30, 2026 and December 31, 2025, 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 $452 million and $377 million, respectively. Income or loss from these investments is recorded in the consolidated statements of operations as Equity in earnings of integral unconsolidated affiliates, net for the Integral Investments and within Equity in earnings of unconsolidated affiliates, net for all other equity investments, including the Waha JVs.
During the first quarter of 2026, the Company sold its 15% equity interest in Cross Country Infrastructure Services, Inc. (“CCI”) for approximately $17 million, resulting in an immaterial gain. Except for an investment for which the Company recorded an other-than-temporary impairment loss of $7.9 million, included within equity in earnings of unconsolidated affiliates, net, in the first quarter of 2026, there were no impairments related to these investments in either of the three or nine months ended September 30, 2026 or 2025.
The Waha JVs. The Waha JVs own and operate certain pipeline infrastructure in the U.S. that transports natural gas to the Mexico 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 $159 million as of September 30, 2026. The Company’s net investment in the Waha JVs, which differs from its proportionate share of the net assets of the Waha JVs due primarily to equity method goodwill associated with capitalized investment costs, totaled approximately $305 million and $290 million as of September 30, 2026 and December 31, 2025, respectively. The table below reflects the investment activity of the Waha JVs for the periods indicated (in millions):

(b)Distributions of earnings from the Waha JVs are included within operating cash flows.
Other Equity Investments. The Company has equity interests in certain other entities that are accounted for as equity method investments, including the Integral Investments. For the nine months ended September 30, 2026, equity contributions related to these entities totaled approximately $1.6 million, and for the nine months ended September 30, 2025, the Company made no equity contributions to these other entities. For the nine months ended September 30, 2026 and 2025, distributions from these entities totaled approximately $15.1 million and $0.5 million, respectively, with the 2026 distributions primarily related to the Company’s Integral Investments.
Certain subsidiaries of MasTec provide services to certain of these equity method investments. Revenue recognized in connection with these services totaled approximately $18.3 million for both the three and nine months ended September 30, 2026. Additionally, 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 $0.6 million and $1.5 million for the three and nine months ended September 30, 2026, respectively, and totaled approximately $0.9 million and $2.9 million for the three and nine months ended September 30, 2025, respectively. As of both September 30, 2026 and December 31, 2025, related amounts payable to these entities totaled approximately $0.3 million. As of September 30, 2026 and December 31, 2025, receivables from these entities totaled approximately $2.0 million and $4.0 million, respectively.
Variable Interest Entities. The Company has determined that certain of its investment arrangements are variable interest entities (“VIEs”). Management assesses its VIEs on an ongoing basis to determine if the Company is the primary beneficiary and if consolidation is required. As of September 30, 2026, management determined that the Company is the primary beneficiary of two of its VIEs, which include an electric utility contractor. Accordingly, these entities have been consolidated within the Company’s financial statements, with the other parties’ interests accounted for as non-controlling interests. As of September 30, 2026 and December 31, 2025, the carrying values of assets associated with the Company’s consolidated VIEs totaled approximately $155.5 million and $187.3 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 $152.0 million and $184.6 million as of September 30, 2026 and December 31, 2025, 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 $12 million and $20 million as of September 30, 2026 and December 31, 2025, respectively, and are recorded within other long-term assets in the consolidated balance sheets, with the decrease primarily attributable to an other-than-temporary impairment loss of $7.9 million, as described above. Management believes that the Company’s maximum exposure to loss for its non-consolidated VIEs, inclusive of additional financing commitments, approximated $13 million and $28 million as of September 30, 2026 and December 31, 2025, respectively.
