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 the construction and maintenance of buildings, roads, bridges, rail, water/sewer systems and other civil infrastructure, including data center infrastructure; 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, 2025 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, 2025 contained in the Company’s 2025 Annual Report on Form 10-K (the “2025 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. Beginning in 2026, certain reclassifications were made to the consolidated statements of operations. The Company now presents a separate “Operating income” subtotal on the consolidated statements of operations, which is common practice within the Company’s industry and enhances comparability with the Company’s peers. Additionally, changes in fair value of acquisition-related contingent items, which are composed of earn-outs and additional payments in connection with prior year acquisitions, have been reclassified from Other expense (income), net to General and administrative expenses. Previously reported periods have been reclassified to conform to the current period presentation. These changes in presentation did not impact previously reported Income before income taxes or Net income, and did not change how the Company evaluates its performance.
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 “Net income attributable to non-controlling interests” in the consolidated statements of operations. 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.
Contracts. The Company derives revenue primarily from construction projects performed under: (i) master service and other service agreements, which generally provide a menu of available services in a specific geographic territory that are utilized on an as-needed basis, and are typically priced using either a time and materials or a fixed price per unit basis; and (ii) contracts for specific projects requiring the construction and installation of an entire infrastructure system, or specified units within an infrastructure system, which may be subject to one or multiple pricing models, including fixed price, unit price, time and materials, or cost plus a markup. Revenue derived from projects performed under master service and other service agreements totaled 40 % and 48 % of consolidated revenue for the three months ended March 31, 2026 and 2025, 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 2
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 both the three months ended March 31, 2026 and 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, 2025 and 2024, respectively. 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 1.8 % for the three months ended March 31, 2026 and 2025, 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.
Remaining performance obligations represent the amount of unearned transaction prices under contracts for which work is wholly or partially unperformed, including the Company’s share of unearned transaction prices from its proportionately consolidated non-controlled joint ventures. As of March 31, 2026, the amount of the Company’s remaining performance obligations was $16.2 billion. Based on current expectations, the Company anticipates it will recognize approximately $8.5 billion, or 52.5 %, of its remaining performance obligations as revenue during 2026, 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 March 31, 2026 and December 31, 2025, the Company’s contract transaction prices included approximately $244 million and $229 million, respectively, of change orders and/or claims for certain contracts that were in the process of being resolved in the ordinary course of its business, including through negotiation, arbitration and other proceedings. These transaction price adjustments, when earned, are included within contract assets or accounts receivable, net of allowance, as appropriate. As of both March 31, 2026 and December 31, 2025, these change orders and/or claims primarily related to certain projects in the Company’s Clean Energy and Infrastructure and Power Delivery segments. The Company actively engages with its customers to complete the final approval process for such amounts and generally expects these processes to be completed within one year . Amounts ultimately realized upon final agreement by customers could be higher or lower than such estimated amounts.
9
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 March 31, 2026 and December 31, 2025, the outstanding payment obligations under the Company’s supplier finance program totaled approximately $138.6 million and $125.6 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 2025 Form 10-K.
Accounting Pronouncements Adopted in 2026
In July 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”). ASU 2025-05 provides a practical expedient that permits an entity to assume that conditions at the balance sheet date remain unchanged over the life of the asset when estimating expected credit losses for current accounts receivable and current contract assets. ASU 2025-05 is effective for fiscal years beginning after December 15, 2025, including interim periods within those fiscal years, with early adoption permitted. The amendments in ASU 2025-05 should be applied prospectively. The Company adopted this ASU prospectively in the first quarter of 2026, and its adoption did not have a material effect on the Company’s consolidated financial statements.
Recently Issued Accounting Pronouncements Not Yet 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 ASU 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.
In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). ASU 2025-06 modernizes the accounting for internal-use software by eliminating the previous stage-based capitalization model so that the guidance is neutral to different software development methods. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years, with early adoption permitted. The amendments in ASU 2025-06 should be applied prospectively, with retrospective application or a modified transition approach permitted. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements.
In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (“ASU 2025-11”). ASU 2025-11 improves existing guidance within Accounting Standards Codification (“ASC”) Topic 270 by clarifying the scope and applicability of the standard and by providing a comprehensive list of interim disclosure requirements. ASU 2025-11 also establishes a principle to disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact this ASU will have on its consolidated financial statements.
Note 2 – Earnings Per Share
Basic earnings per share is computed by dividing net income attributable to MasTec by the weighted average number of common shares outstanding for the period, which excludes non-participating unvested restricted share awards. Diluted earnings per share is computed by dividing net income attributable to MasTec by the weighted average number of fully diluted shares, as calculated primarily under the treasury stock method, which includes the potential effect of dilutive common stock equivalents, such as issued but unvested restricted shares.

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.
2026 Acquisitions. Effective in January 2026, MasTec acquired 86 % of the equity interests of McKee Utility Contractors, LLC, an infrastructure services company that specializes in water and wastewater distribution networks in the south central region of the United States, which is included within the Company’s Clean Energy and Infrastructure segment. MasTec has the option to acquire the remaining noncontrolling interest in the entity following the third anniversary of the consummation date. The aggregate purchase price consisted of $262 million in cash, subject to certain working capital and other contractually agreed-upon adjustments. Determination of the estimated fair values of net assets acquired and consideration transferred for the acquisition, which has been accounted for as a business combination under ASC 805, was preliminary as of March 31, 2026; 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. Acquisition costs for the three months ended March 31, 2026 were immaterial .
The following table summarizes, as of March 31, 2026, the estimated fair values of the consideration paid, net assets acquired, and non-controlling interest assumed for the Company’s 2026 acquisition (in millions):
| Acquisition consideration: | Total | ||||
| Cash paid | $ | ||||

| Total identifiable net assets, excluding cash | $ | ||||
| Goodwill | |||||
| Total net assets, excluding cash | $ | ||||
| Less: non-controlling interest | ( | ||||
| Total net assets acquired | $ | ||||
Amortizing intangible assets related to the acquisition are primarily composed of customer relationships, and to a lesser extent, backlog and trade names. Customer relationships and backlog intangible assets, in the aggregate, totaled approximately $139 million and each had a weighted average life of approximately 13 years and 2 years, respectively. Customer relationships are based on the operational history and the nature of its customers, which are primarily municipalities and utility customers, and backlog is based on estimated cash flows expected to be derived from future work on acquired contracts with customers. The fair values of the customer relationships and acquired backlog intangible assets were determined using the multi-period excess earnings method under the income approach. This method reflects the present value of the projected operating cash flows generated by the intangible asset after considering the cost to realize revenue, and an appropriate discount rate to reflect the time value and risk associated with the invested capital. The significant assumptions used by the Company in determining the fair value of customer relationships intangible assets include future revenues, margins, discount rates, and customer attrition rates. The weighted average life of amortizing intangible assets in the aggregate for the acquisition was 10 years. Amortizing intangible assets are amortized in a manner consistent with the pattern in which the related benefits are expected to be consumed. The preliminary fair value of the noncontrolling interest is estimated based on the price MasTec paid for its 86 % controlling interest. As of March 31, 2026, none of the goodwill balance related to the 2026 acquisition is expected to be tax deductible.
12
Additionally, effective in March 2026, MasTec acquired certain of the assets of an equipment company for an aggregate purchase price of approximately $20 million, which is accounted for as an asset acquisition under ASC 805 and included within the Company’s Pipeline Infrastructure segment.
2025 Acquisitions. During 2025, MasTec acquired all of the equity interests of the following: (i) within the Company’s Communications segment: a telecommunications construction company, effective in July; (ii) within the Company’s Pipeline Infrastructure segment: a construction company specializing in roadway infrastructure, effective in August; and (iii) within the Company’s Clean Energy and Infrastructure segment: a construction company specializing in construction management and design-build services, effective in December. Additionally, MasTec acquired certain operations and assets of a business specializing in install-to-the-home services included within the Company’s Communications segment, effective in November.
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 $87 million in cash, net of cash acquired, and a five year earn-out liability valued at approximately $13 million with respect to one of such acquisitions. 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 March 31, 2026; 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 March 31, 2026, the remaining potential undiscounted earn-out liabilities for the 2025 acquisitions was estimated to be up to $20 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 $35 million of the goodwill balance related to the 2025 acquisitions is expected to be tax deductible as of March 31, 2026.
HMG Additional Payments. The purchase agreement in connection with the 2021 acquisition of Henkels & McCoy Holdings, Inc. (“HMG”) provides for certain additional payments to be made to the sellers if certain receivables are collected by the Company (the “Additional Payments”). Pursuant to the terms of the purchase agreement, a portion of the Additional Payments will be made in cash, with the remainder due in shares of MasTec common stock. The estimated number of potential shares that could be issued related to such Additional Payments will be based on the amounts ultimately collected and the share price as defined within the purchase agreement. Changes in the estimated fair value of potential shares that could be issued, which result from changes in MasTec’s share price as compared with the share price as defined within the purchase agreement, are reflected as unrealized gains or losses within general and administrative expenses. As of March 31, 2026 and December 31, 2025, the estimated fair value of remaining Additional Payments totaled approximately $31 million and $18 million, respectively, which amounts are included within other current liabilities in the consolidated balance sheets. For the three months ended March 31, 2026, the Company collected additional receivables of $4 million and recorded fair value adjustments related to the contingent shares totaling losses of approximately $9 million, and for the three months ended March 31, 2025, such adjustments totaled gains of approximately $1 million.
Pro forma results. The Company’s unaudited pro forma financial results include the results of operations of acquired companies as if those companies had been consolidated as of the beginning of the year prior to their acquisition, and are provided for illustrative purposes only. These unaudited pro forma financial results do not purport to be indicative of the actual results that would have been achieved by the combined companies for the periods indicated, or of the results that may be achieved by the combined companies in the future.
The Company’s unaudited pro forma financial results were prepared by adding the unaudited historical results of acquired businesses to the historical results of MasTec, and then adjusting those combined results for (i) acquisition costs; (ii) amortization expense from acquired intangible assets; (iii) interest expense from cash consideration paid; (iv) interest expense from debt repaid upon acquisition; and (iv) other purchase accounting related adjustments. These unaudited pro forma financial results do not include adjustments to reflect other cost savings or synergies that may have resulted from these acquisitions. Future results may vary significantly due to future events and other factors, many of which are beyond the Company’s control.

Acquisition-related results. The Company defines “acquisition-related” results as results from acquired businesses for the first twelve months following the dates of the respective acquisitions. For the three months ended March 31, 2026, the Company’s consolidated results of operations included acquisition-related revenue of approximately $168.5 million. Acquisition-related net income for the three months ended March 31, 2026 totaled approximately $4.5 million, based on the Company’s consolidated effective tax rate. These acquisition-related results include amortization of acquired intangible assets and certain acquisition integration costs.

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 March 31, 2026, 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 March 31, 2026, the range of potential undiscounted Earn-out liabilities was estimated to be between $23 million and $88 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 $23.8 million and $28.2 million as of March 31, 2026 and December 31, 2025, respectively.
(b)For the three months ended March 31, 2026, fair value adjustments related primarily to increases within the Company’s Pipeline Infrastructure segment. For the three months ended March 31, 2025, fair value adjustments related primarily to increases within the Company’s Clean Energy and Infrastructure and Pipeline Infrastructure segments, which were partially offset by decreases related to acquisitions within the Company’s Power Delivery segment.
Equity Investments
The Company’s equity investments as of March 31, 2026 include the Company’s: (i) 33 % equity interests in Trans-Pecos Pipeline, LLC and Comanche Trail Pipeline, LLC, collectively “Waha JVs”; (ii) interests in certain proportionately consolidated non-controlled joint ventures; and (iii) certain other equity investments. As of March 31, 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 $355 million and $377 million, respectively. 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 months ended March 31, 2026 or 2025.
14
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 $147.9 million as of March 31, 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 $291 million and $290 million as of March 31, 2026 and December 31, 2025, 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 0.5 million and $1.3 million for the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026, there were no related amounts payable to these entities and as of December 31, 2025, related amounts payable totaled approximately $0.3 million. As of March 31, 2026 and December 31, 2025, receivables related to these arrangements totaled approximately $0.6 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 March 31, 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 March 31, 2026 and December 31, 2025, the carrying values of assets associated with the Company’s consolidated VIEs totaled approximately $180.6 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 $177.9 million and $184.6 million as of March 31, 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 $10 million and $20 million as of March 31, 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 $12 million and $28 million as of March 31, 2026 and December 31, 2025, 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 dates indicated (in millions):
| March 31, 2026 | December 31, 2025 | ||||||||||
| Contract billings | $ | $ | |||||||||

| 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. As of March 31, 2026, the increase in contract assets was driven primarily by ordinary course project activity within the Company’s Clean Energy and Infrastructure segment, including the impact of a first quarter acquisition and the timing of billings.
15
For the three months ended March 31, 2026 and 2025, provisions for credit losses totaled recoveries of approximately $0.2 million and $0.7 million, respectively, both of which included certain project-specific reserves. Impairment losses on contract assets were not material in either period.
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 $800.3 million and $747.7 million as of March 31, 2026 and December 31, 2025, respectively, of which deferred revenue comprised approximately $792.3 million and $741.0 million, respectively. The increase in contract liabilities as of March 31, 2026 was driven primarily by ordinary course project activity, including in connection with new project starts within the Company’s Clean Energy and Infrastructure segment, as well as the impact of a first quarter acquisition.
For the three months ended March 31, 2026 and 2025, the Company recognized revenue of approximately $571.3 million and $493.8 million, respectively, related to amounts that were included in deferred revenue as of December 31, 2025 and December 31, 2024, 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 three months ended March 31, 2026 and 2025, the Company sold approximately $172 million and $104 million, respectively, of receivables under financing arrangements for which it continues to manage collections for the transferred receivable, and, as of March 31, 2026 and December 31, 2025, outstanding sold receivables related thereto totaled approximately $171 million and $172 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 March 31, 2026 and 2025, respectively.

Note 10 – Stockholders' Equity
Share Repurchases
The Company’s share repurchase program provides for the repurchase, from time to time, of MasTec common shares in open market transactions or in privately negotiated transactions in accordance with applicable securities laws. There were no share repurchases under the Company’s share repurchase program for the three months ended March 31, 2026. For the three months ended March 31, 2025, the Company repurchased 0.3 million shares of its common stock for an aggregate purchase price totaling $37.1 million, of which $10.2 million was settled in April 2025, under the Company’s March 2020 share repurchase program, which was completed during the second quarter of 2025. As of March 31, 2026, the full amount under the Company’s May 2025 $250 million share repurchase program remains available for future repurchases. The Company’s share repurchase program does not have an expiration date and may be modified or suspended at any time at the Company’s discretion.
Stock-Based Compensation
The Company has stock-based compensation plans, under which shares of the Company’s common stock are reserved for issuance. Under all stock-based compensation plans in effect as of March 31, 2026, there were approximately 3,866,000 shares available for future grants. Non-cash stock-based compensation expense under all plans totaled approximately $8.3 million and $6.9 million for the three months ended March 31, 2026 and 2025, respectively. Income tax benefits associated with stock-based compensation arrangements totaled $4.0 million and $1.6 million for the three months ended March 31, 2026 and 2025, respectively, including net tax benefits related to the vesting of share-based payment awards totaling $2.3 million and $0.4 million, respectively.
Restricted Shares
MasTec grants restricted stock awards and restricted stock units (together, “restricted shares”) to eligible participants, which are valued based on the closing market share price of MasTec common stock on the date of grant. During the restriction period, holders of restricted stock awards are entitled to vote the shares. As of March 31, 2026, total unearned compensation related to restricted shares was approximately $93.8 million, which amount is expected to be recognized over a weighted average period of approximately 2.5 years.

Note 11 – 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 March 31, 2026 and 2025, the Company’s consolidated effective tax rates were 23.8 % and (37.8 )%, respectively. The Company’s effective tax rate for the three months ended March 31, 2026 included income tax benefits primarily due to the vesting of share-based payment awards, offset, in part, by the effects of a higher state income tax rate. For the three months ended March 31, 2025, the Company’s effective tax rate included income tax benefits primarily due to the reversal of uncertain tax position liabilities related to a state audit, offset, in part, by an increase in income tax expense due to higher pre-tax income.
19
On July 4, 2025, new tax legislation was signed into law, known as the One Big Beautiful Bill Act (the “OBBBA”), which makes changes to certain U.S. corporate tax provisions, many of which become effective in 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 impact on the consolidated financial statements. The Company will continue to evaluate the full impact of these legislative changes as additional guidance becomes available.
Note 12 – 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 and digital infrastructure, primarily for wireless and wireline/fiber networks, data center buildout and interconnection, wireless integration and optimization and install-to-the-home services, as well as select utility infrastructure, 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 the construction and maintenance of buildings, roads, bridges, rail, water/sewer systems and other civil infrastructure, including data center infrastructure; 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.
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 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.
In the normal course of business, the Company’s reportable segments enter into transactions with one another. Intersegment transactions are reflected in the results of the respective segments and are included in the measure of segment performance reviewed by the Company’s CODM to evaluate performance and profitability and to allocate resources for each of the Company’s reportable segments; accordingly, eliminations and adjustments related to intersegment transactions are separately presented as “Eliminations” in the tables below. Intersegment revenues and expenses are accounted for as if the transactions were with third parties, as they are based on negotiated fees between the segments involved. All intersegment revenues and expenses are eliminated in consolidation and do not affect consolidated results.
20
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 segment EBITDA to consolidated income before income taxes, 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.

For the three months ended March 31, 2025, AT&T represented approximately 10 % of the Company’s total consolidated revenue. The Company’s relationship with AT&T is based upon multiple separate master service and other service agreements, including for maintenance services and construction/installation contracts for wireless and wireline, and for which the related revenue is included primarily within the Communications segment. Revenue from governmental entities for the three months ended March 31, 2026 and 2025 totaled approximately 12 % and 13 % of total revenue, respectively, all of which was derived from its U.S. operations.
Note 13 – 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.
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 9 – Lease Obligations and Note 14 – 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 March 31, 2026 and December 31, 2025, there were $92.5 million and $90.5 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 March 31, 2026 or December 31, 2025.
22
Performance and Payment Bonds. In the ordinary course of business, MasTec is required by certain customers to provide performance and payment bonds for contractual commitments related to its projects. These bonds provide a guarantee to the customer that the Company will perform under the terms of a contract and that the Company will pay its subcontractors and vendors. If the Company fails to perform under a contract or to pay its subcontractors and vendors, the customer may demand that the surety make payments or provide services under the bond. The Company must reimburse the surety for expenses or outlays it incurs. As of March 31, 2026 and December 31, 2025, outstanding performance and payment bonds approximated $12.4 billion and $10.9 billion, respectively, and estimated costs to complete projects secured by these bonds totaled $5.3 billion and $4.6 billion, respectively. Included in these balances as of March 31, 2026 and December 31, 2025 are $1.3 billion and $1.1 billion, 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 ten 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 March 31, 2026, the Company was not aware of material claims against it in connection with these arrangements. Included in the Company’s cash balances as of March 31, 2026 and December 31, 2025 are amounts held by entities that are proportionately consolidated totaling $46.1 million and $45.0 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 14 – Related Party Transactions for additional information pertaining to the Company’s investment and strategic arrangements.
Self-Insurance. MasTec maintains insurance policies for workers’ compensation, general liability and automobile liability, which are subject to per claim deductibles. The Company is self-insured up to the amount of the deductible. The Company also maintains excess umbrella coverage. The Company manages certain of its insurance liabilities indirectly through its wholly-owned captive insurance company, which reimburses claims up to the applicable insurance limits. Captive insurance-related cash balances totaled approximately $3.9 million and $3.3 million as of March 31, 2026 and December 31, 2025, respectively, which amounts are generally not available for use in the Company’s other operations.
As of March 31, 2026 and December 31, 2025, MasTec’s estimated gross liability for unpaid claims and associated expenses, including incurred but not reported losses related to these policies, totaled $325.2 million and $306.8 million, respectively, of which $227.8 million and $224.9 million were 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 $25.2 million as of March 31, 2026 and December 31, 2025, respectively, of which $23.3 million and $22.4 million were 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 $7.5 million and $2.3 million as of March 31, 2026 and December 31, 2025, 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 $7.4 198.6
Indemnities. The Company generally indemnifies its customers for the services it provides under its contracts, as well as other specified liabilities, which may subject the Company to indemnity claims, liabilities and related litigation. As of both March 31, 2026 and December 31, 2025, the Company had accrued project close-out liabilities of approximately $5
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 1,065 customers for the three months ended March 31, 2026. As of March 31, 2026, no customer represented greater than 10% of the Company’s consolidated net accounts receivable position, which is calculated as accounts receivable, net, less deferred revenue. As of December 31, 2025, one customer accounted for approximately 10 % of the Company’s consolidated net accounts receivable position. The Company derived approximately 41 % and 36 % of its revenue from its top ten customers for the three months ended March 31, 2026 and 2025, respectively.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
This report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are not historical facts but are the intent, belief, or current expectations of our business and industry and the assumptions upon which these statements are based. While management believes that these forward-looking statements are reasonable as and when made, there can be no assurance that future developments affecting us will be those that we anticipate. All comments concerning our expectations for future revenue and operating results are based on our forecasts for our existing operations and do not include the potential impact of any future acquisitions, dispositions or other strategic arrangements. Words such as “anticipates,” “expects,” “intends,” “will,” “could,” “would,” “should,” “may,” “plans,” “believes,” “seeks,” “estimates,” “forecasts,” “continue,” “targets,” “project,” “predict” and variations of these words and negatives thereof and similar expressions are intended to identify forward-looking statements. These statements are not guarantees of future performance and are subject to risks, uncertainties, assumptions and other factors, some of which are beyond our control, are difficult to predict, and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements. Additionally, many of these risks and uncertainties could be amplified by the potential effects of general economic and market conditions, including levels of inflation and market interest rates, geopolitical events, market uncertainty and/or volatility.
These risks and uncertainties include those described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and elsewhere in this report and in our 2025 Annual Report on Form 10-K (“2025 Form 10-K”), including those described under “Cautionary Statement Regarding Forward-Looking Statements” and “Risk Factors,” as updated by Item 1A, “Risk Factors” in this report and other filings we make with the Securities and Exchange Commission (the “SEC”). Forward-looking statements that were true at the time made may ultimately prove to be incorrect or false. Readers are cautioned to not place undue reliance on forward-looking statements, which reflect management’s view only as of the date of this report. We undertake no obligation to update or revise forward-looking statements to reflect changed assumptions, the occurrence of unanticipated events or changes to future operating results.
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 March 31, 2026 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 2025 Form 10-K. In this MD&A, “$” means U.S. dollars unless specified otherwise.
General Economic, Market and Regulatory Conditions
As disclosed within our “Risk Factors” in our 2025 Form 10-K, we are subject to risks related to, among other factors, tariffs and trade actions and geopolitical events that may affect macroeconomic conditions, supply chains, costs and customer demand. Recent geopolitical tensions, most notably conflicts in the Middle East, have contributed to increased volatility and uncertainty in the energy and capital markets, including higher fuel prices used to operate our fleet of vehicles, machinery and equipment, and such volatility could persist if these events are prolonged or escalate. At the same time, a heightened focus on domestic energy security and independence may incentivize oil and gas development and increase demand for renewable alternatives. During 2025 and continuing into 2026, the U.S. government announced or imposed a variety of tariff or other trade actions, prompting retaliatory measures by many countries, including tariffs on U.S. exports and restrictions on certain foreign exports. On February 20, 2026, the U.S. Supreme Court invalidated tariffs imposed under the International Emergency Economic Powers Act (“IEEPA”). Following this decision, the U.S. presidential administration announced its intention to invoke other laws to impose tariffs and announced new tariffs on all countries, in addition to existing non-IEEPA tariffs. Further, on April 2, 2026, the administration issued a Presidential Proclamation under Section 232 of the Trade Expansion Act of 1962 modifying and strengthening existing tariff regimes on aluminum, steel, and copper imports. Collectively, these trade actions have increased the cost of importing certain construction materials into the U.S., including steel, concrete, copper and solar panels, and have contributed to disruption, uncertainty, and volatility in international trade and supply chains. Significant uncertainty remains regarding the status of existing and newly announced tariffs, potential changes or pauses to such tariffs, tariff levels, and whether further additional tariffs or other retaliatory actions may be imposed, modified, or suspended.
We continue to monitor these developments and to evaluate potential impacts and mitigating strategies that we or our customers may implement; however, although these trade actions and ongoing geopolitical events have not had a material impact on our results of operations to date, the related uncertainty and potential changes in trade policy or geopolitical conditions could affect our customers’ capital spending plans, supply chains and operating costs, which could, in turn, adversely affect demand for our services in future periods.
Additionally, 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. In particular, the acceleration of the phaseout of certain clean energy tax credits established under the Inflation Reduction Act may affect the timing and long-term demand for certain renewable energy projects, while other provisions 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 2025 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 the construction and maintenance of buildings, roads, bridges, rail, water/sewer systems and other civil infrastructure, including data center infrastructure; and environmental remediation services. Our customers are primarily in these industries. Including our predecessor companies, we have been in business for over 95 years. As of March 31, 2026, we had approximately 37,000 employees and 790 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.
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 58% of our estimated March 31, 2026 backlog in 2026. The following table presents 18-month estimated backlog by reportable segment as of the dates indicated:
| Reportable Segment (in millions): | March 31, 2026 | December 31, 2025 | March 31, 2025 | ||||||||||||||
Communications | $ | 5,501 | $ | 5,483 | $ | 4,906 | |||||||||||
Clean Energy and Infrastructure | 7,279 | 6,506 | 4,416 | ||||||||||||||
Power Delivery | 6,222 | 5,579 | 5,024 | ||||||||||||||
Pipeline Infrastructure | 1,326 | 1,395 | 1,534 | ||||||||||||||
Other | — | — | — | ||||||||||||||
| Estimated 18-month backlog | $ | 20,328 | $ | 18,963 | $ | 15,880 | |||||||||||
As of March 31, 2026, 44% 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 March 31, 2026, total 18-month backlog differed from the amount of our remaining performance obligations due primarily to the inclusion of $8.4 billion of estimated future revenue under master service and other service agreements within our backlog estimates, as described above, and the exclusion of approximately $4.3 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 2026 differs from the amount of remaining performance obligations expected to be recognized for the same period due primarily to the inclusion of approximately $3.1 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 2025 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 2025 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 the Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our 2025 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. During the three months ended March 31, 2026, there were no material changes in our critical accounting estimates or policies previously disclosed in our 2025 Form 10-K.
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. In our discussions, “acquisition” results are defined as results from acquired businesses for the first twelve months following the dates of the respective acquisitions, with the balance of results for a particular item attributed to “organic” activity. Unless otherwise stated, comparisons are for the quarters ended March 31, 2026 and 2025.

Revenue. On a consolidated basis, revenue increased by $981 million, or 34%, driven by our segment results as follows: revenue increased in our Clean Energy and Infrastructure segment by approximately $414 million, or 45%, in our Pipeline Infrastructure segment by approximately $326 million, or 91%, in our Power Delivery segment by approximately $146 million, or 16%, and in our Communications segment by approximately $121 million, or 18%. Acquisitions contributed $169 million of increased revenue for the three months ended March 31, 2026, whereas organic revenue increased by approximately $813 million, or 29%, as compared with the same period in 2025. See below for details of revenue by segment.
Costs of revenue, excluding depreciation and amortization. Higher levels of revenue contributed an increase of $874 million in costs of revenue, excluding depreciation and amortization, and improved productivity contributed a decrease of approximately $60 million. Costs of revenue, excluding depreciation and amortization, as a percentage of revenue, decreased by approximately 160 basis points to 87.5% of revenue for the three months ended March 31, 2026 from 89.1% of revenue for the same period in 2025. The basis point decrease was due to a combination of project mix and improved project efficiencies, primarily within our Pipeline Infrastructure segment.
Depreciation. As a percentage of revenue, depreciation decreased by approximately 50 basis points, due primarily to higher levels of revenue.
Amortization of intangible assets. Acquisitions contributed approximately $9 million of amortization for the three months ended March 31, 2026, and organic amortization decreased by approximately $3 million, or 9%, due primarily to timing of amortization of intangible assets. As a percentage of revenue, amortization of intangible assets decreased by approximately 10 basis points as compared with the same period in 2025 due, in part, to higher levels of revenue.
General and administrative expenses. Acquisitions contributed $6 million of general and administrative expenses for the three months ended March 31, 2026. Organic general and administrative expenses also increased by approximately $42 million, or 25%, as compared with the same period in 2025, primarily due to an increase in compensation expense, including stock-based compensation and insurance to support business growth, a $10 million increase from changes in the fair value of contingent consideration payable to former owners of an acquired business, approximately $1 million of an increase from changes to estimated Earn-out accruals, and a decrease in net gains on asset sales. Overall, general and administrative expenses decreased by approximately 20 basis points as a percentage of revenue for the three months ended March 31, 2026 as compared with the same period in 2025 due, in part, to higher levels of revenue.
Interest expense, net. The increase in interest expense, net, resulted primarily from higher average balances on our variable rate debt, which accounted for an increase in interest expense of approximately $4 million.
Equity in losses (earnings) of unconsolidated affiliates, net. For the three months ended March 31, 2026, losses from unconsolidated affiliates, net, totaled approximately $4 million, related primarily to an other-than-temporary impairment of $7.9 million on an equity method investment, partially offset by earnings from our investment in the Waha JVs. For the three months ended March 31, 2025, equity in earnings from unconsolidated affiliates, net, totaled approximately $10 million, and related primarily to our investment in the Waha JVs.
Other expense (income), net. For the three months ended March 31, 2026, other expense, net, consisted primarily of approximately $7 million of certain exit costs and other charges, offset, in part, by a gain on the sale of our 15% equity interest in CCI and other miscellaneous income. For the three month period ended March 31, 2025, other income, net, consisted primarily of approximately $2 million of other miscellaneous income, net.
(Provision for) benefit from income taxes. For the three months ended March 31, 2026, our effective tax rate was 23.8% as compared with (37.8)% for the same period in 2025. Our effective tax rate for the three months ended March 31, 2026 included income tax benefits primarily due to the vesting of share-based payment awards, offset, in part, by the effects of a higher state income tax rate, whereas for the three months ended March 31, 2025, our effective tax rate included an income tax benefit primarily due to the reversal of uncertain tax position liabilities related to a state audit, offset, in part, by pre-tax income.
Net income attributable to non-controlling interests. Net income attributable to non-controlling interests was $9 million for the three months ended March 31, 2026, as compared with $2 million for the same period in 2025. The increase was primarily attributable to the increase in activity of certain entities within the Pipeline Infrastructure segment with minority interest holders.
Analysis of Revenue and EBITDA by Segment
We review our operating results by reportable segment. See Note 12 – 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. 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).

(a) For three months ended March 31, 2026 the Other segment EBITDA included approximately $8 million of an other-than-temporary impairment related to an equity method investment.
(b) Represents intersegment eliminations and adjustments related to transactions entered into in the normal course of business.
Communications Segment Results
Revenue. The increase in revenue was driven primarily by organic growth resulting from higher levels of wireless and wireline project activity.
EBITDA. As a percentage of revenue, EBITDA decreased by approximately 100 basis points, or $8 million, primarily due to costs to exit certain markets in our install-to-the-home business. Higher levels of revenue resulted in an increase in EBITDA of approximately $8 million.
Clean Energy and Infrastructure Segment Results
Revenue. Acquisitions contributed $125 million of revenue for the three months ended March 31, 2026, and organic revenue increased by approximately $289 million, or 32%, as compared with the same period in 2025. The increase in organic revenue was due primarily to higher levels of project activity and mix, primarily in renewable and general building projects, including data-center related project activity.
EBITDA. As a percentage of revenue, EBITDA increased by approximately 50 basis points, or $6 million, due to a combination of project mix, improved productivity and efficiencies, primarily from certain renewable and general building project work. Higher levels of revenue resulted in an increase in EBITDA of approximately $26 million.
Power Delivery Segment Results
Revenue. The increase in revenue was due primarily to higher levels of project activity, including timing-related increases in transmission and distribution-related project work, offset, in part, by a decrease in substation-related project activity.
EBITDA. As a percentage of revenue, EBITDA increased by approximately 120 basis points, or $12 million, primarily due to the non-recurrence in the current period of reduced efficiencies at certain project sites in the prior year period. Higher levels of revenue resulted in an increase in EBITDA of approximately $8 million.
Pipeline Infrastructure Segment Results
Revenue. The increase in revenue was due primarily to higher levels of midstream pipeline project activity.
EBITDA. As a percentage of revenue, EBITDA increased by approximately 870 basis points, or $60 million, due primarily to improved efficiencies, as well as the effects of project mix. Higher levels of revenue contributed an increase in EBITDA of approximately $41 million.
Other Segment Results
EBITDA. The EBITDA loss from Other businesses relates primarily to an other-than-temporary impairment related to an equity method investment and other related charges, offset, in part, by equity in earnings from our investments in the Waha JVs.
Corporate Results
EBITDA. For the three months ended March 31, 2026, Corporate EBITDA included approximately $2 million of expense, net, from changes to estimated Earn-out accruals and approximately $9 million of expense, net, from the changes in the fair value of contingent consideration payable to former owners of an acquired business. For the three months ended March 31, 2025, Corporate EBITDA included approximately $1 million of expense, net, from changes to estimated Earn-out accruals and approximately $1 million of income, net, from the changes in the fair value of contingent consideration payable to former owners of an acquired business. Corporate expenses for the three months ended March 31, 2026 not related to the above-described items increased by approximately $18 million as compared with the same period in 2025, due primarily to increases in insurance, compensation, including stock-based compensation, and the effects of timing of ordinary course legal and other settlement matters.

Non-U.S. GAAP Financial Measures
As appropriate, we supplement our reported U.S. GAAP financial information with certain non-U.S. GAAP financial measures, including earnings before interest, income taxes, depreciation and amortization (“EBITDA”), adjusted EBITDA (“Adjusted EBITDA”), adjusted net income (“Adjusted Net Income”), 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, changes in fair value of acquisition-related contingent items and impairments of equity method investments, 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.
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. Additionally, we exclude impairments of equity method investments, as these charges do not reflect the ordinary course of the Company’s business and are not incurred on a predictable basis. 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 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.

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 March 31, 2026 and 2025, our consolidated tax amounts were an expense and a benefit, with effective tax rates, as reported, of 23.8% and (37.8)%, respectively, and as adjusted, were expenses, with effective tax rates of 24.8% and 12.4%, respectively. See Note 11 – 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 three months ended March 31, 2026, we spent approximately $97 million on capital expenditures, or $87 million, net of asset disposals, and incurred approximately $59 million of equipment purchases under finance leases and other financing arrangements. We estimate that we will spend approximately $290 million on capital expenditures, or approximately $220 million, net of asset disposals, in 2026, and we expect to incur approximately $260 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, and for the three months ended March 31, 2026, we used $267 million, net of cash acquired for this purpose. In addition, in most of our acquisitions, we have agreed to make future payments to the sellers that are contingent upon the future earnings performance of the acquired businesses, which we also refer to as “Earn-out” payments. 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 March 31, 2026 was approximately $74 million. Of this amount, approximately $23 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 three months ended March 31, 2026, we made no payments related to our Earn-out liabilities, and for the three months ended March 31, 2025, payments totaled $0.5 million.
Income Taxes. For the three months ended March 31, 2026 and 2025, tax refunds, net of tax payments, totaled approximately $16 million and $2 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 March 31, 2026, 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 $3.9 billion as of March 31, 2026 as compared with $3.5 billion as of December 31, 2025, 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.”
32
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 60 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 March 31, 2026, we had approximately $1,090 million in working capital, defined as current assets less current liabilities, as compared with $1,058 million as of December 31, 2025, an increase of approximately $32 million. Cash and cash equivalents totaled approximately $274 million and $396 million as of March 31, 2026 and December 31, 2025, respectively, for a decrease of $122 million. See discussion below for further detail regarding our cash flows and related activity.
Sources and uses of cash are summarized below (in millions):
Three Months Ended March 31, | |||||||||||
| 2026 | 2025 | ||||||||||
| Net cash provided by operating activities | $ | 98.9 | $ | 78.4 | |||||||
| Net cash used in investing activities | $ | (336.0) | $ | (34.9) | |||||||
| Net cash provided by (used in) financing activities | $ | 114.9 | $ | (97.7) | |||||||
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 $99 million as compared to $78 million for the three months ended March 31, 2026 and 2025, respectively, for an increase in net cash provided by operating activities of approximately $20 million. The increase was due primarily to (i) an increase in net income as compared with the prior period; and (ii) changes in working capital compared with the prior period, including from the positive effect of timing-related changes in accounts payable and accrued expenses, offset, in part, by the unfavorable effect of timing-related changes in accounts receivable, net, primarily driven by higher levels of revenue and an increase in DSO.
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 72 as of March 31, 2026 as compared with DSO of 65 as of December 31, 2025. 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 March 31, 2026 as compared with December 31, 2025 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 $336 million as compared to $35 million for the three months ended March 31, 2026 and 2025, respectively, for an increase of $301 million. We paid $267 million in cash, net of cash acquired related to acquisition activity during the three months ended March 31, 2026, as compared with $5 million for the same period in 2025, for an increase of $262 million. These acquisitions were funded with cash on hand and borrowings under our senior unsecured credit facility. Capital expenditures totaled $97 million, or $87 million, net of asset disposals, for the three months ended March 31, 2026, as compared with $47 million, or $33 million, net of asset disposals, for the same period in 2025, for an increase in cash used in investing activities of approximately $54 million, primarily to support operational growth and the replacement of older machinery and equipment. Proceeds from other investments of approximately $16 million for the three months ended March 31, 2026 related to cash proceeds from the sale of our 15% equity interest in one of our investments.
33
Financing Activities. Net cash provided by financing activities for the three months ended March 31, 2026 was $115 million, as compared to $98 million of net cash used in financing activities for the same period in 2025, for an increase in cash provided by financing activities of approximately $213 million. For the three months ended March 31, 2026, we had $187 million of borrowings, net of repayments, under our credit facility and term loans, as compared with $12 million of repayments, net of borrowings, for the same period in 2025, for an increase in cash provided by financing activities of $198 million. There were no share repurchases for the three months ended March 31, 2026, compared to approximately $27 million of cash settled for shares repurchases for the same period in 2025. These increases in cash provided by financing activities were offset, in part, by an increase of approximately $13 million in payments for tax withholdings on stock-based awards, net of proceeds.
Senior Credit Facility
We have a $1.9 billion senior unsecured credit facility (the “Credit Facility”), which is composed of revolving commitments, and matures on June 26, 2030. As of March 31, 2026, outstanding revolving loans totaled approximately $304 million and availability for revolving loans totaled $1,537 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 8 – Debt in the notes to the audited consolidated financial statements included in our 2025 Form 10-K.
Senior Notes
4.500% Senior Notes. We have $600 million aggregate principal amount of 4.500% senior unsecured notes due August 15, 2028 (the “4.500% Senior Notes”).
5.900% Senior Notes. We have $550 million aggregate principal amount of 5.900% senior unsecured notes due June 15, 2029 (the “5.900% Senior Notes”).
6.625% Senior Notes. We have $75 million aggregate principal amount of 6.625% senior unsecured notes due August 15, 2029 (the “6.625% Senior Notes”).
The senior notes described above are subject to certain provisions and covenants, as more fully described in Note 8 – Debt in the notes to the audited consolidated financial statements included in our 2025 Form 10-K.
2025 Term Loan Facility
As of March 31, 2026, we had $600 million outstanding under a senior unsecured term loan (the “2025 Term Loan Facility”) which matures on June 26, 2028. The 2025 Term Loan Facility is subject to certain provisions and covenants, as more fully described in Note 8 – Debt in the notes to the audited consolidated financial statements included in our 2025 Form 10-K.
Debt Covenants
We were in compliance with the provisions and covenants contained in our outstanding debt instruments as of March 31, 2026, and we expect to be in compliance with these provisions and covenants for the next twelve months.
Additional Information
For detailed discussion and additional information pertaining to our debt instruments, see Note 8 – Debt in the notes to the audited consolidated financial statements included in our 2025 Form 10-K. Also, see Note 8 – 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 13 – Commitments and Contingencies and Note 14 – 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 2025 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 and geopolitical events, 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 dynamic and we expect it to continue for the remainder of 2026 due, in part, to trade actions and geopolitical events 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
34
addition, there is uncertainty of what effect, if any, trade tariffs and recent geopolitical events 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 2025 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-rate debt fluctuates with changes in market interest rates, 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 March 31, 2026, our variable interest rate debt was primarily related to our Credit Facility and 2025 Term Loan Facility. As of March 31, 2026, we had approximately $304 million of outstanding revolving loans under our Credit Facility, with a weighted average interest rate of 4.73%, and $600 million outstanding under our 2025 Term Loan Facility, with a weighted average interest rate of 4.79%. 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 $3 million for the three months ended March 31, 2026.
As of March 31, 2026, 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 $363 million of finance lease obligations, which accrued interest at a weighted average interest rate of approximately 4.94%. 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 three months ended March 31, 2026. 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 three months ended March 31, 2026. 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 three months ended March 31, 2026, foreign currency translation losses, net, totaled approximately $1 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 March 31, 2026. We may enter into foreign currency derivative contracts in the future to manage such exposure.
Other Market Risk
As discussed in Note 4 – Fair Value of Financial Instruments in the notes to the consolidated financial statements, which is incorporated by reference, we have certain investments that may be subject to market risk and could be subject to volatility based on market conditions.
ITEM 4. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures. As of the end of the period covered by this Quarterly Report on Form 10-Q, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within time periods specified in the SEC’s rules and forms.
Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.
Based on management’s evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of March 31, 2026.
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 March 31, 2026 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
