1. BUSINESS AND ORGANIZATION, BASIS OF PRESENTATION AND ACCOUNTING POLICIES:
Quanta Services, Inc. (together with its subsidiaries, Quanta) is a leading provider of comprehensive infrastructure solutions for the electric and gas utility, renewable energy, communications, pipeline and energy industries in the United States, Canada, Australia and select other international markets. We provide engineering, procurement, construction, upgrade and repair and maintenance services for infrastructure within each of these industries, including electric power transmission and distribution networks; substation facilities; wind and solar generation and transmission and battery storage facilities; communications and cable multi-system operator networks; gas utility systems; pipeline transmission systems and facilities; and downstream industrial facilities.
These unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X for interim financial information. Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States (GAAP), have been condensed or omitted pursuant to those rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto of Quanta’s Annual Report on Form 10-K for the year ended December 31, 2022.2023. Quanta believes that the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations, comprehensive income and cash flows with respect to the interim condensed consolidated financial statements have been included.
The results of Quanta have historically been subject to seasonal fluctuations. The results of operations, and comprehensive income and operating cash flows for the interim periods are not necessarily indicative of the results for the entire fiscal year. The results of Quanta have historically been subject to significant seasonal fluctuations.

2. NEW ACCOUNTING PRONOUNCEMENTS:
Recently Adopted Guidance
In October 2021, the Financial Accounting Standards Board (FASB) issued an update that requires recognition and measurement of contract assets and contract liabilities acquired in a business combination in accordance with FASB ASC 606 (Revenue from Contracts with Customers). At the acquisition date, an acquirer should account for the related contract revenue in accordance with FASB ASC 606. This update is effective for interim and annual periods beginning after December 15, 2022, with amendments generally applied prospectively. Quanta adopted this update effective January 1, 2023, and it did not have a material impact on Quanta’s consolidated financial statements.
New Accounting Pronouncement Not Yet Adopted
In June 2022, the FASB issued an update that clarifies the guidance in FASB ASC 820 (Fair Value Measurement) for equity securities subject to contractual sale restrictions. The update prohibits entities from taking into account contractual restrictions on the sale of equity securities when estimating fair value and introduces required disclosures for such transactions. This update is effective for interim and annual periods beginning after December 15, 2023. Early adoption is permitted. This guidance will increase the fair market value of the consideration paid in equity securities in a business combination, and therefore it may increase the amount allocated to goodwill. Quanta will adoptadopted this update byeffective January 1, 2024, and it isdid not expected to have a material impact on Quanta’s consolidated financial statements.
New Accounting Pronouncements and Disclosure Rules Not Yet Adopted
In March 2024, the U.S. Securities and Exchange Commission (SEC) issued its final climate disclosure rule (the Final Rule) that requires public entities to disclose certain material climate-related information in annual reports and registration statements, including disclosure of material impacts as a result of severe weather events and other natural conditions and material Scope 1 and Scope 2 greenhouse gas emissions. Disclosures will be required prospectively, with information for prior periods required only to the extent the information was disclosed in a prior SEC filing. Certain requirements of the Final Rule are effective for fiscal years beginning on or after January 1, 2025, with phase-in periods for additional requirements. However, on April 4, 2024, the SEC issued a stay pending judicial review of the Final Rule in U.S. federal court. Quanta is currently assessing the effect of the Final Rule.
In December 2023, the FASB issued an update that expands disclosures for tax rate reconciliation tables, primarily by requiring disaggregation of income taxes paid by jurisdiction, as well as greater disaggregation within the rate reconciliation. This update is effective for fiscal years beginning after December 15, 2024 and interim periods within fiscal years beginning after December 15, 2025. Early adoption and retrospective application are permitted. Quanta is currently assessing the effect of this update.
In November 2023, the FASB issued an update that, among other things, requires public entities to disclose significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within each reported measure of segment profit or loss, provide an amount for other segment items by reportable segment and provide all segment disclosures required on an annual basis in interim periods. Additionally, the update requires entities to disclose the title and position of the CODM and an explanation of how the CODM uses the reported measures(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. This update is effective for fiscal years beginning after

December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, and retrospective application is required. Quanta is currently assessing the effect of this update.

Total revenues
Total revenues

Under fixed-price contracts, as well as unit-price contracts with more than an insignificant amount of partially completed units, revenue is recognized as performance obligations are satisfied over time, with the percentage of completion generally measured as the percentage of costs incurred to total estimated costs for such performance obligation. Approximately 54.0%57.5% and 51.7%50.1% of Quanta’s revenues recognized during the three months ended June 30,March 31, 2024 and 2023 and 2022 were associated with this revenue recognition method, and 52.4% and 51.5% of Quanta’s revenues recognized during the six months ended June 30, 2023 and 2022 were associated with this revenue recognition method.
Performance Obligations
As of June 30, 2023March 31, 2024 and December 31, 2022,2023, the aggregate transaction price allocated to unsatisfied or partially satisfied performance obligations was approximately $12.48$14.88 billion and $8.80$13.89 billion, with 70.7%64.6% and 72.1%66.9% expected to be recognized in the subsequent twelve months. These amounts represent management’s estimates of the consolidated revenues that are expected to be realized from the remaining portion of firm orders under fixed price contracts not yet completed or for which work had not yet begun as of such dates. For purposes of calculating remaining performance obligations, Quanta includes all estimated revenues attributable to consolidated joint ventures and variable interest entities, revenues from funded and unfunded portions of government contracts to the extent they are reasonably expected to be realized, and revenues from change orders and claims to the extent management believes additional contract revenues will be earned and are deemed probable of collection. Excluded from remaining performance obligations are potential orders under MSAs and expected revenues under certain non-fixed price contracts expected to be completed within one year.contracts.
Contract Estimates and Changes in Estimates
Actual revenues and project costs can vary, sometimes substantially, from previous estimates due to changes in a variety of factors, including unforeseen or changed circumstances not included in Quanta’s cost estimates or covered by its contracts. Some of the factors that can result in positive changes in estimates on projects include successful execution through project

risks, reduction of estimated project costs or increases of estimated revenues. Some of the factors that can result in negative changes in estimates include concealed or unknown site conditions; changes to or disputes with customers regarding the scope of services; changes in estimates related to the length of time to complete a performance obligation; changes or delays with respect to permitting and regulatory requirements and materials; changes in the cost of equipment, commodities, materials or skilled labor; unanticipated costs or claims due to delays or failure to perform by customers or third parties; customer failure to provide, or supply chain and logistical challenges related to, required materials or equipment; errors in engineering, specifications or designs; project modifications; adverse weather conditions, natural disasters, and other emergencies; and performance and quality issues causing delay (including payment of liquidated damages) or requiring rework or replacement. Any changes in estimates could result in changes to profitability or losses associated with the related performance obligations.

QUANTA SERVICES, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
(Unaudited)

Additionally, changes in cost estimates on certain contracts may result in the issuance of change orders, which can be approved or unapproved by the customer, or the assertion of contract claims. Quanta recognizes amounts associated with change orders and claims as revenue if it is probable that the contract price will be adjusted and the amount of any such adjustment can be reasonably estimated.
As of June 30, 2023March 31, 2024 and December 31, 2022,2023, Quanta had recognized revenues of $745.1$774.8 million and $549.3$778.9 million related to unapproved change orders and claims included as contract price adjustments primarily in “Contract assets” in the accompanying consolidated balance sheets. These change orders and claims were in the process of being negotiated in the normal course of business and represent management’s estimates of additional contract revenues that have been earned and are probable of collection.

The largest component of the revenues recognized related to unapproved change orders and claims as of June 30, 2023March 31, 2024 and of the increase relative to December 31, 20222023 is associated with a large renewable transmission project in Canada. During 2021 and 2022, decreased productivity and additional costs arose from delays, administrative requirements and labor issues due to the COVID-19 pandemic, including incremental governmental requirements and worksite restrictions. During the six months ended June 30, 2023, additional costs arose from residual impacts associated with such delays, administrative requirements and labor issues due to the COVID-19 pandemic, includingaforementioned items, as well as work resequencing and acceleration, access delays, and logistical challenges along withand other issues outside of Quanta’s control. As of March 31, 2024, the project was substantially completed.
Changes in estimates can result in the recognition of revenue in a current period for performance obligations that were satisfied or partially satisfied in prior periods or the reversal of previously recognized revenue if the currently estimated revenue is less than the previous estimate. The impact of a change in contract estimate is measured as the difference between the revenue or gross profit recognized in the prior period as compared to the revenue or gross profit which would have been recognized had the revised estimate been used as the basis of recognition in the prior period. Changes in estimates can also result in contract losses, which are recognized in full when they are determined to be probable and can be reasonably estimated.
Revenues were positively impacted by 0.7% and 1.5%0.1% during each of the three months ended June 30, 2023 and 2022 as a result of changes in estimates associated with performance obligations on fixed price contracts partially satisfied prior to March 31, 20232024 and 2022. Revenues were positively impacted by 0.3% and 1.0% during the six months ended June 30, 2023 and 2022 as a result of changes in estimates associated with performance obligations on fixed price contracts partially satisfied prior to December 31, 20222023 and 2021.

However, Quanta’s large renewable transmission project in Canada was negatively impacted by $20.7 million due to changes to estimated project costs during this period, as mentioned above.
Operating results for the three months ended June 30, 2022There were favorably impacted by $62.3 million, or 10.0%, of gross profit as a result of aggregate changes in contract estimates related to projects that were in progress as of March 31, 2022. The overall favorable impact resulted from net positiveno material changes in estimates across a large number of projects, primarily as a result of favorable performance and successful mitigation of risks and contingencies as the projects progressed to completion. Partially offsetting the aggregate net favorable impact to gross profit was a negative change in estimate of $13.0 million for the three months ended June 30, 2022, associated with the large renewable transmission project in Canada, described above.
Operating results for the six months ended June 30, 2022 were favorably impacted by $72.7 million, or 6.2% of gross profit as a result of aggregate changes in contract estimates related to projects that were in progress at December 31, 2021. The overall favorable impact resulted from net positive changes in estimates across a large number of projects, primarily as a result of favorable performance and successful mitigation of risks and contingencies as the projects progressed to completion.

During the sixthree months ended June 30,March 31, 2024 and 2023, Quanta recognized revenue of approximately $897.8$952.6 million and $641.1 million related to contract liabilities outstanding as of the end of theeach respective prior year.
Accounts Receivable, Allowance for Credit Losses and Concentrations of Credit Risk
Quanta determines its allowance for credit losses based on an estimate of expected credit losses for financial instruments, primarily accounts receivable and contract assets. The assessment of the allowance for credit losses involves certain judgments and estimates. Management estimates the allowance balance using relevant available information from internal and external sources relating to past events, current conditions and reasonable and supportable forecasts. Expected credit losses are estimated by evaluating trends inwith respect to Quanta’s historical write-off experience and applying historical loss ratios to pools of financial assets with similar risk characteristics. Quanta has determined that it has two risk pools for the purpose of calculating its historical credit loss experience.
Quanta’s historical loss ratio and its determination of its risk pools, which are used to calculate expected credit losses, may be adjusted for changes in customer credit concentrations within its portfolio of financial assets, itschanges in customers’ ability to pay, and other considerations, such as economic and market changes, changes to regulatory or technological environments affecting customers and the consistency between current and forecasted economic conditions and the historical economic conditions used to derive historical loss ratios. At the end of each quarter, management reassesses these and other relevant factors, including the impact of uncertainty and challenges in the overall economy and in Quanta’s industries and markets, which currently include(e.g., inflationary pressure, supply chain and other logistical challenges and increased interest rates.rates).
Additional allowance for credit losses is established for financial asset balances with specific customers where collectability has been determined to be improbable based on customer specific facts and circumstances. Quanta considers

accounts receivable delinquent after 30 days but, absent certain specific considerations, generally does not consider such amounts delinquent in its credit loss analysis unless the accounts receivable are at least 120 days outstanding. In addition, management monitors the credit quality of its receivables by, among other things, obtaining credit ratings for significant customers, assessing economic and market conditions and evaluating material changes to a customer’s business, cash flows and financial condition. Should anticipated recoveries relating to receivables fail to materialize, including anticipated recoveries relating to bankruptcies or other workout situations, Quanta could experience reduced cash flows and losses in excess of current allowances provided.
Accounts receivable are written-off against the allowance for credit losses if they are deemed uncollectible.

The above activity relates to the largest risk pool Quanta utilizes for assessing credit loss. The second risk pool represents approximately 12% of Quanta’s consolidated financial instruments as of March 31, 2024 and did not have any allowance for credit loss or experience any credit loss during the periods presented. Quanta’s customers generally have high credit ratings. In addition, the customers in the second risk pool typically pre-approve invoices and often receive project financing.
Provision for credit losses is included in “Selling, general and administrative expenses” in the consolidated statements of operations.
Quanta is subject to concentrations of credit risk related primarily to its receivable position with customers, which includes amounts related to billed and unbilled accounts receivable and contract assets for services Quanta has performed for customers. Quanta grants credit under normal payment terms, generally without collateral. OneAs of March 31, 2024 and December 31, 2023, one customer within the Renewable Energy Infrastructure Solutions segment associated with the large renewable transmission project in Canada described above represented 15% and 13%10% of Quanta’s consolidated receivable position, as of June 30, 2023 and December 31, 2022.

which includes amounts related to contracts assets. No customer represented 10% or more of Quanta’s consolidated revenues for the three or six months ended June 30, 2023March 31, 2024 or 2022.2023.
Certain contracts allow customers to withhold a small percentage of billings pursuant to retainage provisions, and such amounts are generally due upon completion of the contract and acceptance of the project by the customer. Based on Quanta’s experience in recent years, the majority of these retainage balances are expected to be collected within one year. Retainage balances with expected settlement dates within one year of June 30, 2023March 31, 2024 and December 31, 20222023 were $483.9$624.2 million and $397.6$610.0 million, which are included in “Accounts receivable.” Retainage balances with expected settlement dates beyond one year were $147.8$88.4 million and $136.2$78.7 million as of June 30, 2023March 31, 2024 and December 31, 20222023 and are included in “Other assets, net.”
Quanta recognizes unbilled receivables for non-fixed price contracts within “Accounts receivable” in certain circumstances, such as when revenues have been earned and recorded but the amount cannot be billed under the terms of the contract until a later date or when amounts arise from routine lags in billing. These balances do not include revenues recognized for work performed under fixed-price contracts and unit-price contracts with more than an insignificant amount of partially completed units, as these amounts are recorded as “Contract assets.” As of June 30, 2023March 31, 2024 and December 31, 2022,2023, unbilled receivables included in “Accounts receivable” were $929.4$794.3 million and $823.9$743.6 million. The increase in unbilled receivables was primarily due to significant increases in work and certain delays in billing related to certain large customers. Quanta also recognizes unearned revenues for non-fixed price contracts when cash is received prior to recognizing revenues for the related performance obligation. Unearned revenues, which are included in “Accounts payable and accrued expenses,” were $61.6$66.7 million and $59.6$58.6 million as of June 30, 2023March 31, 2024 and December 31, 2022.2023.

Underground Utility and Infrastructure Solutions (Underground and Infrastructure). Quanta’s Underground and Infrastructure segment provides comprehensive infrastructure solutions to customers involved in the transportation, distribution, storage, development and processing of natural gas, oil and other products.
Corporate and Non-allocated Costs include corporate facility costs; non-allocated corporate salaries, benefits and incentive compensation; acquisition and integration costs; non-cash stock-based compensation; amortization related to intangible assets; asset impairment related to goodwill and intangible assets; and change in fair value of contingent consideration liabilities.
Quanta’s segment results are derived from the types of services provided across its operating companies in each of its end user markets. Quanta’s entrepreneurial business model allows multiple operating companies to serve the same or similar customers and to provide a range of services across end user markets. Reportable segment information, including revenues and operating income by type of work, is gathered from each operating company. Classification of operating company revenues by type of work for segment reporting purposes can require judgment on the part of management.
In addition, integrated operations and common administrative support for Quanta’s operating companies require that allocations be made to determine segment profitability, including allocations of certain corporate shared and indirect operating costs as well as general and administrative costs.
The following table sets forth segment revenues and segment operating income (loss) and operating margins for the three and six months ended June 30, 2023March 31, 2024 and 2022.2023. Operating margin is calculated by dividing operating income (loss) by revenues. The following table

Quanta has also guaranteed the residual value under certain of its equipment operating leases and real estate finance leases, agreeing to pay any difference between the residual value and the fair market value of the underlying asset at the date of lease termination. Historically, the fair value of the assets at the time of lease termination generally has approximated or exceeded the residual value guarantees, and therefore such guarantees are not expected to result in significant payments.

10. INCOME TAXES:
Quanta’s effective tax rates for the three months ended June 30,March 31, 2024 and 2023 were a provision of 14.3% and 2022 were 29.4% and 30.0%. Quanta’s effective tax rates for the six months ended June 30, 2023 and 2022 were 20.0% and 20.9%a benefit of 3.7%. The tax rates for the sixthree months ended June 30,March 31, 2024 and 2023 and 2022 were favorably impacted by the recognition of $32.4$21.6 million and $21.2$32.0 million of benefits that resulted from equity incentive awards vesting at a higher fair market value than their grant date fair value. The effective tax rates for the three and six months ended June 30, 2022 were unfavorably impacted by the valuation allowance on the losses on Starry, which is further described below.
Quanta regularly evaluates valuation allowances established for deferred tax assets for which future realization is uncertain, including in connection with changes in tax laws. The estimation of required valuation allowances includes estimates of future taxable income. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Quanta considers projected future taxable income and tax planning strategies in making this assessment. If actual future taxable income differs from these estimates, Quanta may not realize deferred tax assets to the extent estimated. During the three and six months ended June 30, 2022, Quanta recognized $41.7 million and $50.0 million of unrealized losses on its investment in Starry and recorded a valuation allowance against such unrealized losses. During the three months ended March 31, 2023, Starry filed for bankruptcy under Chapter 11 of the U.S. Bankruptcy Code, as amended. Upon resolution of the bankruptcy proceedings, a portion of Quanta’s unrealized losses may become deductible for income tax purposes.
As of June 30, 2023,March 31, 2024, the total amount of unrecognized tax benefits relating to uncertain tax positions was $46.3$47.4 million, a net increase of $4.7$2.3 million from December 31, 2022,2023, which primarily resulted from a $4.7 million increase related to positions expected to be taken in 2023.2024. Quanta’s consolidated federal income tax returns for tax years 2017, 2018, and 2020 through 20212022 remain open to examination by the IRS, as the applicable statute of limitations periods have not yet expired. Additionally, various state and foreign tax returns filed by Quanta and certain subsidiaries for multiple periods remain under examination by various U.S. state and foreign tax authorities. Quanta does not consider any U.S. state in which it does business to be a major tax jurisdiction. Quanta believes it is reasonably possible that within the next 12 months unrecognized tax benefits may decrease by up to $11.9$8.9 million as a result of settlement of these examinations or as a result of the expiration of certain statute of limitations periods.

11. EQUITY:

On May 23, 2023, Quanta’s Board of Directors approved a new stock repurchase program that authorizes Quanta to purchase, from time to time through June 30, 2026, up to $500 million of its outstanding common stock.

During the sixthree months ended June 30,March 31, 2024 and 2023, and 2022, Quanta recognized $15.0$9.6 million and $10.6$4.9 million of non-cash stock compensation expense related to PSUs to be settled in common stock. As of June 30, 2023,March 31, 2024, there was an estimated $43.4$55.9 million of total unrecognized compensation expense related to unearned and unvested PSUs. This amount is based on forecasted attainment of performance metrics and estimated forfeitures of unearned and unvested PSUs. The compensation expense related to outstanding PSUs can vary from period to period based on changes in forecasted achievement of established performance goals and the total number of shares of common stock that Quanta anticipates will be issued upon vesting of such PSUs. This cost is expected to be recognized over a weighted average period of 1.972.16 years.
During each of the sixthree months ended June 30,March 31, 2024 and 2023, 0.3 million and 2022, 0.7 million shares of common stock were earned and either issued or deferred for future issuance under Quanta’s deferred compensation plans in connection with earned and vested PSUs. The approximate fair values of PSUs earned and vested during the sixthree months ended June 30,March 31, 2024 and 2023 were $75.4 million and 2022 were $115.5 million, and $72.4 million.
RSUs to be Settled in Cash
During the six months ended June 30, 2023 and 2022, compensation expense related to RSUs to be settled in cash was $8.6 million and $6.7 million. RSUs that are anticipated to be settled in cash are not included in the calculation of weighted average shares outstanding for earnings per share, and the estimated earned value of such RSUs is calculated at the end of each reporting period based on the market value of Quanta’s common stock and is classified as a liability. Quanta paid $9.7 million and $8.7 million to settle liabilities related to cash-settled RSUs in the six months ended June 30, 2023 and 2022. Accrued liabilities for the estimated earned value of outstanding RSUs to be settled in cash were $10.3 million and $11.0 million as of June 30, 2023 and December 31, 2022.respectively.

13. EMPLOYEE BENEFIT PLANS:
Deferred Compensation Plans
Quanta maintains non-qualified deferred compensation plans under which eligible directors and key employees may defer their receipt of certain cash compensation and/or the settlement of certain stock-based awards. As of June 30, 2023March 31, 2024 and December 31, 2022,2023, the liability related to deferred cash compensation under these plans, including amounts contributed by Quanta, was $81.4$101.8 million and $67.4$88.9 million, the majority of which was included in “Insurance and other non-current liabilities” in the accompanying condensed consolidated balance sheets. Additionally, as of June 30, 2023March 31, 2024 and December 31, 2022,2023, the settlement and issuance of 207,512176,305 and 252,026174,079 shares of common stock underlying certain stock-based awards had been deferred under these plans, and such issuances are scheduled to occur in future periods.

To provide for future obligations related to deferred cash compensation under these plans, Quanta has invested in corporate-owned life insurance (COLI) policies covering certain participants in the deferred compensation plans, the underlying investments of which are intended to be aligned with the investment alternatives elected by plan participants. The COLI assets are recorded at their cash surrender value, which is considered their fair market value, and as of June 30, 2023March 31, 2024 and December 31, 2022,2023, the fair market values were $76.6$95.7 million and $64.0$83.4 million and were included in “Other assets, net” in the accompanying condensed consolidated balance sheets. The level of inputs for these fair value measurements is Level 2.

14. COMMITMENTS AND CONTINGENCIES:
Legal Proceedings
Quanta is from time to time party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, property damage, breach of contract, negligence or gross negligence, environmental liabilities, wage and hour and other employment-related
26

QUANTA SERVICES, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
(Unaudited)

damages, punitive damages, consequential damages, civil penalties or other losses, or injunctive or declaratory relief. With respect to all such lawsuits, claims and proceedings, Quanta records a reserve when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. In addition, Quanta discloses matters for which management believes a material loss is at least reasonably possible.
The assessment of whether a loss is probable or reasonably possible, and whether the loss or a range of loss is estimable, often involves a series of complex judgments about future events. In all instances, management has assessed the matter based on current information and made a judgment concerning its potential outcome, giving due consideration to the nature of the claim, the amount and nature of damages sought and the probability of success and taking into account, among other things, negotiations with claimants, discovery, settlements and payments, judicial rulings, arbitration and mediation decisions, advice of internal and external legal counsel, and other information and events pertaining to a particular matter. Costs incurred for litigation are expensed as incurred. Except as otherwise stated below, none of these proceedings are expected to have a material adverse effect on Quanta’s consolidated financial position, results of operations or cash flows. However, management’s judgment may prove materially inaccurate, and such judgment is made subject to the known uncertainties of litigation.
Peru Project Dispute
In 2015, Redes Andinas de Comunicaciones S.R.L. (Redes), a majority-owned subsidiary of Quanta, entered into two separate contracts with an agency of the Peruvian Ministry of Transportation and Communications (MTC), currently Programa Nacional de Telecomunicaciones (PRONATEL), as successor to Fondo de Inversion en Telecomunicaciones (FITEL), pursuant to which Redes would design, construct and operate certain telecommunication networks in rural regions of Peru. The aggregate consideration provided for in the contracts was approximately $248 million, consisting of approximately $151 million to be paid during the construction period and approximately $97 million to be paid during a 10-year post-construction operation and maintenance period. At the beginning of the project, FITEL made advance payments totaling approximately $87 million to Redes, which were secured by two on-demand advance payment bonds posted by Redes to guarantee proper use of the payments in the execution of the project. Redes also provided two on-demand performance bonds in the aggregate amount of $25 million to secure performance of its obligations under the contracts.
During the construction phase, the project experienced numerous challenges and delays, primarily related to issues which Quanta believes were outside of the control of and not attributable to Redes, including, among others, weather-related issues, local opposition to the project, permitting delays, the inability to acquire clear title to certain required parcels of land and other delays which Quanta believes were attributable to FITEL/PRONATEL. In response to various of these challenges and delays, Redes requested and received multiple extensions to certain contractual deadlines and relief from related liquidated damages.
28

QUANTA SERVICES, INC. AND SUBSIDIARIES

(Unaudited)

However, in April 2019, PRONATEL provided notice to Redes claiming that Redes was in default under the contracts due to the delays and that PRONATEL would terminate the contracts if the alleged defaults were not cured. Redes responded by claiming that it was not in default, as the delays were due to events not attributable to Redes, and therefore PRONATEL was not entitled to terminate the contracts. PRONATEL subsequently terminated the contracts for alleged cause prior to completion of Redes’ scope of work, exercised the on-demand performance bonds and advance payment bonds against Redes, and indicated its intention to claim damages, including liquidated damages under the contracts. As of the date of the contract terminations, Redes had incurred costs of approximately $157 million related to the design and construction of the project and had received approximately $100 million of payments (inclusive of the approximately $87 million advance payments).
In May 2019, Redes filed for arbitration before the Court of International Arbitration of the International Chamber of Commerce (ICC) against PRONATEL and the MTC. In the arbitration, Redes claimed that PRONATEL: breached and wrongfully terminated the contracts; wrongfully executed the advance payment bonds and the performance bonds; and was not entitled to the alleged amount of liquidated damages, and sought compensation for various damages arising from PRONATEL’s actions in the initially claimed amount of approximately $190 million. In August 2022, Redes received the decision of the arbitration tribunal, which unanimously found in favor of Redes in connection with its claims and ordered, among other things, (i) repayment of the amounts collected by PRONATEL under the advance payment bonds and the performance bonds; (ii) payment of amounts owed for work completed by Redes under the contracts; (iii) payment of lost income in connection with Redes’ future operation and maintenance of the networks; and (iv) payment of other related costs and damages to Redes as a result of the breach and improper termination of the contracts (including costs related to the execution of the bonds, costs related to the transfer of the networks and legal and expert fees). Accordingly, the arbitration tribunal awarded Redes approximately $177 million. In addition, per the terms of the arbitration decision, interest will accrue on the amount owed up to the date of payment.
The decision of the arbitration tribunal is final, with limited grounds on which PRONATEL and the MTC may seek to annul the decision in Peruvian courts. In December 2022, Redes filed an enforcement proceeding with respect to each project contract to secure recovery of the arbitration award, and PRONATEL and the MTC filed an annulment proceeding with respect
27

QUANTA SERVICES, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
(Unaudited)

to each project contract. The enforcement and annulment proceedings are pending withinwere filed with different commercial courts in Lima, Peru. In April 2023 and August 2023, Redes received favorable rulings in each of the annulment proceedings rejecting the grounds for annulment; however, PRONATEL and the MTC are pursuing, and are expected to continue to pursue, certain remaining legal challenges to such rulings. DecisionsFinal decisions with respect to the enforcement proceedings are expected later in 2023.2024. Additionally, in December 2022, following the favorable arbitration ruling, Quanta received $100.5 million pursuant to coverage under an insurance policy for the improper collection by PRONATEL and the MTC of the advance payment and performance bonds, and in January 2023 Quanta received $6.7 million pursuant to coverage under an insurance policy for nonpayment by PRONATEL and the MTC of amounts owed for work completed by Redes. Quanta is continuing to pursue collection of the ICC arbitration award and any amount collected would result in repayment of an equal amount to the insurers up to the amount received from the insurers.
Quanta also reserves the right to seek full compensation for the loss of its investment under applicable legal regimes, including investment treaties and customary international law, as well as to seek resolution through direct discussions with PRONATEL or the MTC. In connection with these rights, in May 2020 Quanta’s Dutch subsidiary delivered to the Peruvian government an official notice of dispute arising from the termination of the contracts and related acts by PRONATEL (which are attributable to Peru) under the Agreement on the Encouragement and Reciprocal Protection of Investments between the Kingdom of the Netherlands and the Republic of Peru (Investment Treaty). The Investment Treaty protects Quanta’s subsidiary’s indirect ownership stake in Redes and the project, and provides for rights and remedies distinct from the ICC arbitration. In December 2020, Quanta’s Dutch subsidiary filed a request for the institution of an arbitration proceeding against Peru with the International Centre for Settlement of Investment Disputes (ICSID) related to Peru’s breach of the Investment Treaty, which was registered by ICSID in January 2021. In the ICSID arbitration, Quanta’s Dutch subsidiary claims, without limitation, that Peru: (i) treated the subsidiary’s investment in Redes and the project unfairly and inequitably; and (ii) effectively expropriated the subsidiary’s investment in Redes and the project. In addition, Quanta’s Dutch subsidiary is seeking full compensation for all damages arising from Peru’s actions, including but not limited to (i) the fair market value of the investment and/or lost profits; (ii) attorneys’ fees and arbitration costs; (iii) other related costs and damages and (iv) pre- and post-award interest. The ICSID arbitration hearing on the merits occurred in the second quarter of 2023 and a decision is currently expected in the firstsecond half of 2024.
Quanta believes Redes is entitled to all amounts awarded by the ICC arbitration tribunal, and that its Dutch subsidiary is entitled to other amounts associated with the pending ICSID arbitration proceeding. Quanta and Redes intend to vigorously pursue recovery of the amounts awarded by the ICC arbitration tribunal and take additional legal actions deemed necessary to enforce the ICC arbitration decision. However, due to the inherent uncertainty involved with, among other things, the
29

QUANTA SERVICES, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
(Unaudited)

challenges to the annulment decisions, enforcement and related proceedings, the ultimate timing and conclusion with respect to collection of the amountamounts of the ICC arbitration award remains unknown.
As a result of the contract terminations and the inherent uncertainty involved in arbitration proceedings and recovery of amounts owed, during the three months ended June 30, 2019, Quanta recorded a charge to earnings of $79.2 million, which included a reduction of previously recognized earnings on the project, a reserve against a portion of the project costs incurred through the project termination date, an accrual for a portion of the alleged liquidated damages, and the estimated costs to complete the project turnover and close out the project. Quanta also initially recorded a contract receivable of approximately $120 million related to the project during the three months ended June 30, 2019, which includes the amounts collected by PRONATEL through exercise of the advance payment bonds and performance bonds. As of June 30, 2023,March 31, 2024, the total amount of the receivable was not changed and is included in “Other assets, net” in the accompanying condensed consolidated balance sheet. Additionally, with respect to the amounts received pursuant to coverage under the insurance policies described above, $107.2 million is included in “Insurance and other non-current liabilities” in the accompanying condensed consolidated balance sheet as of June 30, 2023.March 31, 2024.
After considering, as discussed above, that the ultimate timing and conclusion with respect to collection of the full amountamounts associated with the ICC arbitration award remains unknown, Quanta has not recognized a gain in the current period. To the extent amounts in excess of the current receivable are determined to be realizable, a gain would be recorded in the period such determination is made. However, if Quanta is ultimately not successful with respect to collection of the ICC arbitration award through annulment or otherwise, or with respect to its claims in the pending ICSID arbitration proceeding, this matter could result in an additional significant loss that could have a material adverse effect on Quanta’s consolidated results of operations and cash flows.
Lorenzo Benton v. Telecom Network Specialists, Inc., et al.
In June 2006, plaintiff Lorenzo Benton filed a class action complaint in the Superior Court of California, County of Los Angeles, alleging various wage and hour violations against Telecom Network Specialists (TNS), a former subsidiary of Quanta. Quanta retained liability associated with this matter pursuant to the terms of Quanta’s sale of TNS in December 2012. Benton represents a class of workers that includes all persons who worked on certain TNS projects, including individuals that TNS retained through numerous staffing agencies. The plaintiff class in this matter is seeking damages for unpaid wages, penalties associated with the failure to provide meal and rest periods and overtime wages, interest and attorneys’ fees. In January 2017, the trial court granted a summary judgment motion filed by the plaintiff class and found that TNS was a joint employer of the class members and that it failed to provide adequate meal and rest breaks and failed to pay overtime wages. During 2019 and 2020, the parties filed additional summary judgment and other motions, and a bench trial on liability and damages was held. Liability and damages have been determined by the trial court, with the amount of liability for TNS, including interest through the date of the trial court’s orders, determined to be approximately $9.5 million. Separately, in 2022, the court issued a final ruling awarding attorneys’ fees and costs to plaintiffs in the amount of approximately $17.3 million. Quanta continues to contest its liability and the damages calculations asserted by the plaintiff class in this matter and believes the court’s decisions on these matters are not supported by controlling law and that attorneys’ fees would only be recoverable by the plaintiff class in the event Quanta’s appeal of the trial court’s rulings on liability and damages is unsuccessful.
Additionally, in November 2007, TNS filed cross complaints for indemnity and breach of contract against the staffing agencies, which employed many of the individuals in question. In December 2012, the trial court heard cross-motions for summary judgment filed by TNS and the staffing agencies pertaining to TNS’s demand for indemnity. The court denied TNS’s motion and granted the motions filed by the staffing agencies; however, the California Appellate Court reversed the trial court’s decision in part and instructed the trial court to reconsider its ruling. In February 2017, the court denied a new motion for summary judgment filed by the staffing companies and has since stated that the staffing companies would be liable to TNS for any damages owed to the class members that the staffing companies employed. However, Quanta currently believes that, due to solvency issues, any contribution from the staffing companies may not be substantial.
The final amount of liability and attorneys’ fees, if any, payable in connection with this matter remains the subject of pending litigation and will ultimately depend on various factors, including the outcome of the parties’ appeals of the trial court’s rulings on liability, damages, and attorneys’ fees and costs, and the solvency of the staffing agencies. Based on review and analysis of the trial court’s rulings on liability, Quanta does not believe, at this time, that it is probable this matter will result in a material loss. However, if Quanta is unsuccessful in this litigation and the staffing agencies are unable to fund damages owed to class members, based on rulings issued by the trial court, Quanta believes the range of reasonably possible loss to Quanta upon final resolution of this matter could be up to approximately $26.8 million, plus any additional attorneys’ fees, interest, and expenses awarded to the plaintiff class.

Hallen Acquisition Assumed Liability
In August 2019, in connection with the acquisition of The Hallen Construction Co., Inc. (Hallen), Quanta assumed certain contingent liabilities associated with a March 2014 natural gas-fed explosion and fire in the Manhattan borough of New York City, New York. The incident resulted in, among other things, loss of life, personal injury and the destruction of two buildings and other property damage. After investigation, the National Transportation Safety Board determined that the probable cause of the incident was the failure of certain natural gas infrastructure installed by Consolidated Edison, Inc. (Con Ed) and the failure of certain sewer infrastructure maintained by the City of New York. Pursuant to a contract with Con Ed, Hallen had performed certain work related to such natural gas infrastructure and agreed to indemnify Con Ed for certain claims, liabilities and costs associated with its work. Numerous lawsuits are pending in New York state courts related to the incident, which generally name Con Ed, the City of New York and Hallen as defendants. These lawsuits are at various stages and generally seek unspecified damages and, in some cases, punitive damages, for wrongful death, personal injury, property damage and business interruption.
Hallen’s liabilities associated with this matter are expected to be covered under applicable insurance policies or contractual remedies negotiated by Quanta with the former owners of Hallen. When a loss becomes probable and estimable, Quanta expects to record an accrual of the estimated liability, offset by a receivable in the same amount related to such insurance coverage and contractual remedies. As of June 30, 2023, Quanta had not recorded an accrual related to this matter, as the ultimate amount of liability in connection with this matter remains subject to uncertainties associated with pending litigation, including, among other things, the likelihood and potential amount of damages that could be asserted or awarded. While Quanta believes the liabilities associated with this matter will not exceed the amount of available insurance coverage and contractual remedies, this matter could result in a loss that is in excess of, or not covered by, such remedies, which could have a material adverse effect on Quanta’s consolidated financial condition, results of operations and cash flows.
Silverado Wildfire Matter
During 2022 and 2023, two of Quanta’s subsidiaries received tenders of defense and demands for preservation of evidence from Southern California Edison Company (SCE) related to lawsuits filed from April 2021 through July 2023March 2024 against SCE and T-Mobile USA, Inc. (T-Mobile) in the Superior Court of California, County of Orange. The lawsuits generally
28

QUANTA SERVICES, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
(Unaudited)

assert property damage and related claims on behalf of certain individuals and subrogation claims on behalf of insurers relating to damages caused by a wildfire that began in October 2020 in Orange County, California (the Silverado Fire) and that is purported to have damaged approximately 13,000 acres. The lawsuits allege the Silverado Fire originated from utility poles in the area, generally claiming that each defendant failed to adequately maintain, inspect, repair or replace its overhead facilities, equipment and utility poles and remove vegetation in the vicinity; that the utility poles were overloaded with equipment from shared usage; and that SCE failed to de-energize its facilities during red flag warnings for a Santa Ana wind event. The lawsuits allege the Silverado Fire started when SCE and T-Mobile equipment contacted each other and note the Orange County Fire Department is investigating whether a T-Mobile lashing wire contacted an SCE overhead primary conductor in high winds. T-Mobile has filed cross-complaints against SCE alleging, among other things, that the ignition site of the Silverado Fire encompassed two utility poles replaced by SCE or a third party engaged by SCE, and that certain equipment, including T-Mobile’s lashing wire, was not sufficiently re-secured after the utility pole replacements. One of Quanta’s subsidiaries performed planning and other services related to the two utility poles, and another Quanta subsidiary replaced the utility poles and reattached the electrical and telecommunication equipment to the new utility poles in March 2019, approximately 19 months before the Silverado Fire. Pursuant to the general terms of a master services agreement and a master consulting services agreement between the Quanta subsidiaries and SCE, the subsidiaries agreed to defend and indemnify SCE against certain claims arising with respect to performance or nonperformance under the agreements. The SCE tender letters seek contractual indemnification and defense from Quanta’s subsidiaries for the claims asserted against SCE in the lawsuits and the T-Mobile cross-complaints.
Quanta’s subsidiaries intend to vigorously defend against the lawsuits, the T-Mobile cross-complaints and any other claims asserted in connection with the Silverado Fire. Quanta will continue to review additional information in connection with this matter as litigation and resolution efforts progress, and any such information may potentially allow Quanta to determine an estimate of potential loss, if any. As of June 30, 2023,March 31, 2024, Quanta had not recorded an accrual with respect to this matter, and Quanta is currently unable to reasonably estimate a range of reasonably possible loss, if any, because there are a number of unknown facts and legal considerations that may impact the amount of any potential liability. Quanta also believes that to the extent its subsidiaries are determined to be liable for any damages resulting from this matter, its insurance would be applied to any such liabilities over its deductible amount and its insurance coverage would be adequate to cover such potential liabilities. However, the ultimate amount of any potential liability and insurance coverage in connection with this matter remains subject to uncertainties associated with pending and potential future litigation.

Insurance
Quanta is insured for, among other things, employer’s liability, workers’ compensation, auto liability, aviation and general liability claims. Quanta manages and maintains a portion of its casualty risk indirectly through its wholly-owned captive insurance company, which insures all claims up to the amount of the applicable deductible of its third-party insurance programs, as well as with respect to certain other amounts.
As of June 30, 2023March 31, 2024 and December 31, 2022,2023, the gross amount accrued for employer’s liability, workers’ compensation, auto liability, general liability, and group health claims totaled $322.9$371.0 million and $319.6$351.7 million, of which $210.7$237.0 million and $209.8$229.2 million are included in “Insurance and other non-current liabilities,” and the remainder is included in “Accounts payables and accrued expenses.” Related insurance recoveries/receivables as of June 30, 2023March 31, 2024 and December 31, 20222023 were $5.3$5.5 million and $5.8$4.9 million, of which $0.3$0.9 million and $0.3 million are included in “Prepaid expenses and other current assets” and $5.0$4.6 million and $5.5$4.6 million are included in “Other assets, net.”
Bonds and Parent Guarantees
As of June 30, 2023,March 31, 2024, the total amount of the outstanding performance bonds was estimated to be approximately $6.3$8.1 billion. Quanta’s estimated maximum exposure related to the value of the performance bonds outstanding is lowered on each bonded project as the cost to complete is reduced, and each commitment under a performance bond generally extinguishes concurrently with the expiration of its related contractual obligation. The estimated cost to complete these bonded projects was approximately $2.4 billion as of June 30, 2023.
Capital Commitments and Other Committed Expenditures
As of June 30, 2023,March 31, 2024, Quanta had $59.9$64.2 million of outstanding capital commitments associated with investments in unconsolidated affiliates, the majority of which relates to a limited partnership interest in a fund that targets investments in certain portfolio companies that operate businesses related to the transition to a reduced-carbon economy.
As of March 31, 2024, Quanta had $133.7 million of unfilled production orders withprimarily related to its fleet of vehicles, which have expected delivery dates during the remainder of 2023 and $36.5 million of production orders with expected delivery dates in 2024, for capital commitments primarily related to the expansion of its equipment fleet. The majority of this amount relates to the expansion of Quanta’s equipment fleet in order to accommodate manufacturer lead times on certain types of vehicles. Although Quanta has committed to purchase these vehicles at the time of their delivery, Quanta anticipates
29

QUANTA SERVICES, INC. AND SUBSIDIARIES

that the majority of these orders will be assigned to third party leasing companies and made available under certain master equipment lease agreements, thereby releasing Quanta from its capital commitments.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
General
The following discussion and analysis of the financial condition and results of operations of Quanta Services, Inc. (together with its subsidiaries, Quanta, we, us or our) should be read in conjunction with our condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report and with our 20222023 Annual Report, which was filed with the SEC on February 23, 202322, 2024 and is available on the SEC’s website at www.sec.gov and on our website at www.quantaservices.com. The discussion below contains forward-looking statements that are based upon our current expectations and are subject to uncertainty and changes in circumstances. Actual results may differ materially from these expectations due to inaccurate assumptions and known or unknown risks and uncertainties, including those identified in Cautionary Statement About Forward-Looking Statements and Information above, in Item 1A. Risk Factors of Part II of this Quarterly Report and in Item 1A. Risk Factors of Part I of our 20222023 Annual Report.

Overview
Our secondfirst quarter 20232024 results reflect increased demand for our services, as consolidated revenue and operating income increased in all of our segments as compared to the secondfirst quarter of 2022.2023, primarily due to increased revenues and operating income for our Renewable Energy Infrastructure Solutions (Renewable Energy) segment.
With respect to our Electric Power Infrastructure Solutions (Electric Power) segment, utilities are continuing to invest significant capital in their electric power delivery systems through multi-year grid modernization and reliability programs, as well as system upgrades and hardening programs in response to recurring severe weather events. We have also experienced high demand for new and expanded transmission, substation and distribution infrastructure needed to reliably transport power.
With respect to our Renewable Energy Infrastructure Solutions (Renewable Energy) segment, the transition to a reduced-carbon economy is continuing to drive demand for renewable generation and related infrastructure (e.g., high-voltage electric transmission and substation infrastructure), as well as interconnection services necessary to connect and transmit renewable-generated electricity to existing electric power delivery systems. Our acquisition of Blattner Holding Company and its operating subsidiaries (collectively, Blattner) in the fourth quarter of 2021, has had a significant incremental impact on our ability to perform these services. Despite these positive longer-term trends, certain of our customers experienced supply chain challenges during 2022 and into 2023, the first halftiming of 2023certain projects within this segment were negatively impacted by supply chain challenges that resulted in delays and shortages of, and increased costs for, materials necessary for certain projects, particularly sourcing restrictions related to solar panels necessary for the utility scaleutility-scale solar industry. Based on indications within this marketindustry and delays in availability of power transformers impacting the electric power and renewable energy industries. While certain challenges associated with solar panel sourcing improved during the second quarter of 2023, we expect thecould experience and continue to monitor other potential supply chain challenges and sourcing restrictions related tothat could impact the availability and/or cost of renewable infrastructure project components, including solar panels to improve throughout the remainder of the year.generation components, in future periods.
With respect to our Underground Utility and Infrastructure Solutions (Underground and Infrastructure) segment, in 2022 and throughduring the secondfirst quarter of 20232024 we experiencedcontinued to experience strong demand for our services focused on utility spending, in particular our gas distribution services to natural gas utilities that are implementing modernization programs, and our downstream industrial services, as these customers continued to move forward with certain maintenance and capital spending that was deferred during the course of the COVID-19 pandemic.previously deferred. Additionally, during the first half of 2023 we generated increasedalthough revenues associated with large pipeline projects in Canada.Canada increased in 2022 and 2023, as compared to prior years, we anticipate that revenues associated with these projects will continue to fluctuate.
During the sixthree months ended June 30, 2023,March 31, 2024, increased revenues resulted in $165.8and operating income contributed to $238.0 million of net cash provided by operating activities. Availableactivities, a 520% increase compared to the three months ended March 31, 2023, which allowed us to execute our business plan, including the strategic acquisition of certain businesses, for which we utilized $384.1 million of cash, net of cash acquired, and the payment of $13.7 million in dividends associated with our common stock. Additionally, as of March 31, 2024, available commitments under our senior credit facility, andcombined with our cash and cash equivalents, as of June 30, 2023 were $1.77totaled $2.58 billion.
We expect the strong demand for our services will continue. Our remaining performance obligations and backlog were $12.48$14.88 billion and $27.20$29.90 billion as of June 30, 2023,March 31, 2024, representing increasesan increase of 41.8%7.1%, and 12.9%a decrease of 0.7% relative to December 31, 2022.2023. For a reconciliation of backlog to remaining performance obligations, the most comparable financial measure prepared in conformity with generally accepted accounting principles in the United States (GAAP), see Non-GAAP Financial Measures below.

Significant Factors Impacting Results
Our revenues, profit, margins and other results of operations can be influenced by a variety of factors in any given period, including those described in Item 1. Business and Item 1A. Risk Factors of Part I ofin our 20222023 Annual Report, and those factors
32

have caused fluctuations in our results in the past and are expected to cause fluctuations in our results in the future. Additional information with respect to certain of those factors is provided below.
35

Seasonality. Typically, our revenues are lowest in the first quarter of the year because cold, snowy or wet conditions can create challenging working environments that are more costly for our customers or cause delays on projects. In addition, infrastructure projects often do not begin in a meaningful way until our customers finalize their capital budgets, which typically occurs during the first quarter. Second quarter revenues are typically higher than those in the first quarter, as some projects begin, but continued cold and wet weather can often impact productivity. Third quarter revenues are typically the highest of the year, as a greater number of projects are underway and operating conditions, including weather, are normally more accommodating. Generally, revenues during the fourth quarter are lower than the third quarter but higher than the second quarter, as many projects are completed and customers often seek to spend their capital budgets before year end. However, the holiday season and inclement weather can sometimes cause delays during the fourth quarter, reducing revenues and increasing costs. These seasonal impacts are typical for our U.S. operations, but seasonality for our international operations may differ. For example, revenues for certain projects in Canada are typically higher in the first quarter because projects are often accelerated in order to complete work while the ground is frozen and prior to the break up, or seasonal thaw, as productivity is adversely affected by wet ground conditions during warmer months.
Weather, natural disasters and emergencies. The results of our business in a given period can be impacted by adverse weather conditions, severe weather events, natural disasters or other emergencies, which include, among other things, heavy or prolonged snowfall or rainfall, hurricanes, tropical storms, tornadoes, floods, blizzards, extreme temperatures, wildfires, post-wildfire floods and debris flows, pandemics and earthquakes. Climate change has the potential to increase the frequency and extremity of severe weather events. These conditions and events can negatively impact our financial results due to, among other things, the termination, deferral or delay of projects, reduced productivity and exposure to significant liabilities due to failure of electrical power or other infrastructure on which we have performed services. However, severe weather events can also increase our emergency restoration services, which typically yield higher margins due in part to higher equipment utilization and absorption of fixed costs.
Demand for services. We perform the majority of our services under existing contracts, including MSAs and similar agreements pursuant to which our customers are not committed to specific volumes of our services. Therefore our volume of business can be positively or negatively affected by fluctuations in the amount of work our customers assign us in a given period, which may vary by geographic region. Examples of items that may cause demand for our services to fluctuate materially from quarter to quarter include: the financial condition of our customers, their capital spending and their access to and cost of capital; acceleration of any projects or programs by customers (e.g., modernization or hardening programs); economic and political conditions on a regional, national or global scale, including availability of renewable energy tax credits; interest rates; governmental regulations affecting the sourcing and costs of materials and equipment; other changes in U.S. and global trade relationships; and project deferrals and cancellations.
Revenue mix and impact on margins. The mix of revenues based on the types of services we provide in a given period will impact margins, as certain industries and services provide higher-margin opportunities. Our larger or more complex projects typically include, among others, transmission projects with higher voltage capacities; pipeline projects with larger-diameter throughput capacities; large-scale renewable generation projects; and projects with increased engineering, design or construction complexities, more difficult terrain or geographical requirements, or longer distance requirements. These projects typically yield opportunities for higher margins than our recurring services under MSAs described above, as we assume a greater degree of performance risk and there is greater utilization of our resources for longer construction timeframes. However, larger projects are subject to additional risk of regulatory delay and cyclicality. Project schedules also fluctuate, particularly in connection with larger, more complex or longer-term projects, which can affect the amount of work performed in a given period. Furthermore, smaller or less complex projects typically have a greater number of companies competing for them, and competitors at times may more aggressively pursue available work. A greater percentage of smaller scale or less complex work also could negatively impact margins due to the inefficiency of transitioning between a greater number of smaller projects versus continuous production on fewer larger projects. As a result, at times we may choose to maintain a portion of our workforce and equipment in an underutilized capacity to ensure we are strategically positioned to deliver on larger projects when they move forward.
Project variability and performance. Margins for a single project may fluctuate period to period due to changes in the volume or type of work performed, the pricing structure under the project contract or job productivity. Additionally, our productivity and performance on a project can vary period to period based on a number of factors, including unexpected project difficulties or site conditions (including in connection with difficult geographic characteristics); project location, including locations with challenging operating conditions; whether the work is on an open or encumbered right of way; inclement weather or severe weather events; environmental restrictions or regulatory delays; protests, public activism, other political activity or legal challenges related to a project; and the performance of third parties. Moreover, we currently generate a significant portion of our revenues under fixed price contracts, and fixed price contracts are more common in connection with our larger and more
33

complex projects that typically involve greater performance risk. Under these contracts, we assume risks related to project estimates and execution, and project revenues can vary, sometimes substantially, from our original projections due to a variety of factors,
36

including the additional complexity, timing uncertainty or extended bidding, regulatory and permitting processes associated with these projects. These variations can result in a reduction in expected profit, the incurrence of losses on a project or the issuance of change orders and/or assertion of contract claims against customers. See Revenue Recognition - Contract Estimates and Changes in Estimates in Note 3 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this Quarterly Report.
Subcontract work and provision of materials. Work that is subcontracted to other service providers generally yields lower margins, and therefore an increase in subcontract work in a given period can decrease operating margins. In recent years, we have subcontracted approximately 20% of our work to other service providers. Our customers are usually responsibleAdditionally, under certain contracts, including contracts for supplying the materials for their projects. However, under some contractsengineering, procurement and construction services, we agree to procure all or part of the required materials. MarginsWhile we attempt to structure our agreements with customers and suppliers to account for the impact of increased materials procurement requirements or fluctuations in the cost of materials we procure, our margins may be lower on projects where we furnish a significant amount of materials, as our markup on materials is generally lower than our markup on labor costs, and in a given period an increase in the percentage of work with greater materials procurement requirements may decrease our overall margins, including in some cases our assuming price risk. Furthermore, fluctuations in the price or availability of materials, equipment and consumables that we or our customers utilize could impact costs to complete projects.

Revenues. Revenues increased due to a $465.1$575.9 million increase in revenues from our Renewable Energy segment a $215.8 million increase in revenues from our Electric Power segment and a $135.7$36.2 million increase in revenues from our Underground and Infrastructure segment, offset by a $9.1 million decrease in revenues from our Electric Power segment. See Segment Results below for additional information and discussion related to segment revenues.
Cost of services. Costs of services primarily includes wages, benefits, subcontractor costs, materials, equipment, and other direct and indirect costs, including related depreciation. The increase in cost of services generally correlates to the increase in revenues.
3734

Equity in earnings of integral unconsolidated affiliates. The decrease in equity in earnings was primarily driven by the timing of completion of projects associated with certain of our integral affiliates, as well as the reimbursement of certain large costs to LUMA by the owner of the transmission and distribution system during the three months ended June 30, 2022.

Selling, general and administrative expenses. The increase was partiallyprimarily attributable to an aggregate $28.7a $19.0 million increase inrelated to recently acquired businesses and a loss of $10.7 million on the following items to support business growth: compensation expense, largely associated with increased salaries due primarily to headcount growth; and travel and related expenses. Also contributing to the increasedisposal of a non-core business. Partially offsetting these increases was a $14.2$10.3 million increasedecrease in deferred compensation liabilities primarily driven by fair market value increasesacquisition and an $11.9 million increase in legal and other consulting services. The fair market value changes in deferred compensation liabilities were largely offset by changes in the fair value of corporate-owned life insurance (COLI) assets associated with the deferred compensation plan, which are included in “Other (expense) income, net” as discussed below.integration costs.
Amortization of intangible assets. The decreaseincrease was primarily related to a $40.7 million reduction ofincremental amortization of intangible assetsexpense associated with backlog for Blattner, which was fully amortized by the third quarter of 2022.recent acquisitions.
Operating income. Operating income was positively impacted by a $13.0 million decrease in corporate and non-allocated costs, which includes amortization expense, as well as a $11.9 million increase in operating income for our Electric Power segment, a $28.8$39.2 million increase in operating income for our Renewable Energy segment and a $17.3$12.9 million increase in operating income for our Electric Power segment, partially offset by a $14.7 million decrease in operating income for our Underground and Infrastructure segment.segment and a $7.9 million increase in corporate and non-allocated costs, which includes amortization expense. Results for each of our business segments and our corporate and non-allocated costs are discussed in the Segment Results section below.
Interest and other financing expenses. The increasedecrease primarily resulted from the impact of higher interest rates on our outstandingan approximate 20% reduction in average variable rate debt during the three months ended June 30, 2023outstanding as compared to the three months ended June 30, 2022.
Other income (expense), net. The net other expense for the three months ended June 30, 2022 included a $41.7 million unrealized loss that resulted from the remeasurement of the fair value of our investment in Starry Group Holdings, Inc. (Starry). TheMarch 31, 2023, partially offset by an approximate 80 basis point increase in other income, netinterest rates for three months ended June 30, 2023our outstanding variable rate debt as compared to the three months ended June 30, 2022 alsoMarch 31, 2023.
Other income, net. The increase primarily resulted from a $13.4$12.2 million favorable mark-to-market valuationgain on the sale of the COLI assets associated with our deferred compensation plans, partially offset by $9.1an investment in a non-integral unconsolidated affiliate, of which $4.9 million lower equity in earnings of non-integral affiliates.was attributable to a non-controlling interest (as described below).
Provision for (benefit from) income taxes. The effective tax rates for the three months ended June 30,March 31, 2024 and 2023 were a provision of 14.3% and 2022 were 29.4% and 30.0%a benefit of 3.7%. The effective tax rate for the three months ended March 31, 2024 was impacted by the recognition of a $21.6 million tax benefit resulting from non-cash stock-based compensation awards vesting at higher fair market value than their grant date fair value, as compared to the recognition of a $32.0 million tax benefit for the three months ended March 31, 2023.
Net income attributable to non-controlling interests. The increase in net income attributable to non-controlling interests is primarily related to the $4.9 million gain on the sale of the investment in a non-integral equity unconsolidated affiliate recorded during the three months ended March 31, 2024, as further described in Note 6 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this Quarterly Report.
Comprehensive income. See Statements of Comprehensive Income in Item 1. Financial Statements of Part I of this Quarterly Report. Comprehensive income increaseddecreased by $125.2$2.7 million in the three months ended June 30, 2023March 31, 2024 as compared to the three months ended June 30, 2022,March 31, 2023, primarily due to a $70.4$31.0 million decrease related to foreign currency translation adjustments, which was partially offset by a $29.1 million increase in net income and a $55.0 million increase in foreign currency translation gains.income. The predominant functional currencies for our operations outside the U.S. are Canadian and Australian dollars. The increase in foreignForeign currency translation gains primarily resulted from strengthening of the Canadian dollar against the U.S. dollarloss for the three months ended June 30, 2023 as compared to the three months ended June 30, 2022.
EBITDA and adjusted EBITDA. See Non-GAAP Financial Measures below for a reconciliation of EBITDA and adjusted EBITDA to net income attributable to common stock, the most comparable GAAP financial measure. EBITDA increased 26.8%, or $92.1 million, to $436.3 million as compared to $344.2 million for the three months ended June 30, 2022, and adjusted EBITDA increased 11.8%, or $50.0 million, to $472.1 million as compared to $422.1 million for the three months ended June 30, 2022.

Revenues. Revenues increased due to a $597.8 million increase in revenues from our Renewable Energy segment, a $413.2 million increase in revenues from our Electric Power segment and a $268.9 million increase in revenues from our Underground and Infrastructure segment. See Segment Results below for additional information and discussion related to segment revenues.
Cost of services. Costs of services primarily includes wages, benefits, subcontractor costs, materials, equipment, and other direct and indirect costs, including related depreciation. The increase in cost of services generally correlates to the increase in revenues.
Equity in earnings of integral unconsolidated affiliates. The decrease in equity in earnings was primarily driven by the timing of completion of projects associated with certain of our integral affiliates, as well as the reimbursement of certain large costs to LUMA by the owner of the transmission and distribution system during the six months ended June 30, 2022.
Selling, general and administrative expenses. The increase was partially attributable to an aggregate $50.9 million increase in the following items to support business growth: compensation expense, largely associated with increased salaries due primarily to headcount growth; and travel and related expenses. Also contributing to the increase was a $22.3 million increase in expense related to deferred compensation liabilities. The fair market value changes in deferred compensation liabilities were largely offset by changes in the fair value of COLI assets associated with the deferred compensation plan, which are included in “Other (expense) income, net” as discussed below. Additional items contributing to the increase were an $11.5 million increase in legal and other consulting services; a $7.8 million increase in expenses associated with acquired businesses; a $5.6 million increase in depreciation expense primarily related to our new corporate headquarters and a $5.5 million increase in provision for credit allowance.
Amortization of intangible assets. The decrease was primarily due to a $88.8 million reduction of amortization of intangible assets associated with backlog for Blattner, which was fully amortized by the third quarter of 2022.
Operating income. Operating income was positively impacted by a $30.5 million decrease in corporate and non-allocated costs, which includes amortization expense, as well as a $30.7 million increase in operating income for our Underground and Infrastructure segment and a $23.6 million increase in operating income for our Electric Power segment. Partially offsetting the
39

positive impact of these items was a $5.5 million decrease in operating income for our Renewable Energy segment. Results for each of our business segments and corporate and non-allocated costs are discussed in the Segment Results section below.
Interest and other financing expenses. The increaseMarch 31, 2024 primarily resulted from the impact of higher interest rates on our outstanding variable rate debt during the six months ended June 30, 2023 as compared to the six months ended June 30, 2022.
Other income (expense), net. The net other expense for the six months ended June 30, 2022 was primarily due to an unrealized loss of $50.0 million that resulted from the remeasurementstrengthening of the fair value of our investment in Starry. The increase in other income forU.S. dollar against the six months ended June 30, 2023 compared to the six months ended June 30, 2022 resulted from a $20.7 million favorable mark-to-market valuation of the COLI assets associated with our deferred compensation plan, partially offset by a $12.9 million decrease in equity in earnings of non-integral affiliates.
Provision for income taxes. The effective tax rates for the six months ended June 30, 2023 and 2022 were 20.0% and 20.9%. The tax rate for the six months ended June 30, 2023 was favorably impacted by the recognition of a $32.4 million benefit that resulted from equity incentive awards vesting at a higher fair market value than their grant date fair market value, as compared to the recognition of $21.2 million associated with this tax benefit for the six months ended June 30, 2022.
Comprehensive income. See Statements of Comprehensive Income in Item 1. Financial Statements of Part I of this Quarterly Report. Comprehensive income increased by $125.0 million in the six months ended June 30, 2023 as compared to the six months ended June 30, 2022, primarily due to a $82.4 million increase in net income and a $41.8 million increase in foreign currency translation gains. The predominant functional currencies for our operations outside the U.S. are Canadian and Australian dollars. The increase in foreign currency translation gains primarily resulted from strengthening of the Canadian dollar against the U.S. dollar for the six months ended June 30, 2023 as compared to the six months ended June 30, 2022.
EBITDA and adjusted EBITDA. See Non-GAAP Financial Measures below for a reconciliation of EBITDA and adjusted EBITDA to net income attributable to common stock, the most comparable GAAP financial measure. EBITDA increased 11.4%, or $73.8 million, to $723.8 million as compared to $650.0 million for the six months ended June 30, 2022, and adjusted EBITDA increased 5%, or $36.8 million, to $804.4 million as compared to $767.6 million for the six months ended June 30, 2022.

Segment Results
We report our results under three reportable segments: Electric Power, Renewable Energy and Underground and Infrastructure. Reportable segment information, including revenues and operating income by type of work, is gathered from each of our operating companies. Classification of our operating company revenues by type of work for segment reporting purposes can at times require judgment on the part of management. Our operating companies may perform joint projects for customers in multiple industries, deliver multiple types of services under a single customer contract or provide service offerings to various industries. For example, we perform joint trenching projects to install distribution lines for electric power and natural gas customers. Integrated operations and common administrative support for operating companies require that certain allocations be made to determine segment profitability, including allocations of corporate shared and indirect operating costs, as well as general and administrative costs. Certain corporate costs are not allocated, including corporate facility costs; non-allocated corporate salaries, benefits and incentive compensation; acquisition and integration costs; non-cash stock-based compensation; amortization related to intangible assets; asset impairments related to goodwill and intangible assets; and change in fair value of contingent consideration liabilities.

Electric Power Infrastructure Solutions Segment Results
Revenues. The increasedecrease in revenues for the three months ended June 30, 2023March 31, 2024 was primarily due to increased spendingsoftness in the distribution market, partially offset by our utility customers on grid modernization and hardening and approximately $80$55 million in revenues attributable to acquired businesses.
Operating Income. Operating income increased for the three months ended June 30, 2023 primarily due to the increase in revenues. Operating margin decreased during the three months ended June 30, 2023 partially due to $9.2 million of lower equity in earnings from our integral unconsolidated affiliates as discussed above, as well as lower than expected utilization of resources in Canada, which is expected to continue throughout the rest of the year. The negative impact of these items on operating margin was partially offset by improved operating margin associated with telecommunications projects.
Renewable Energy Infrastructure Solutions Segment Results
Revenues. The increase in revenues for the three months ended June 30, 2023 was primarily due to increased demand and improved supply chain dynamics, as well as approximately $75 million in revenues attributable to acquired businesses.
Operating Income. The increase in operating income was primarily due to the increase in revenues during the three months ended June 30, 2023. The decrease in operating margin during the three months ended June 30, 2023 was primarily attributable to increased unabsorbed costs related to higher levels of fixed costs for resources required to support the expected increase in project activity in the second half of 2023 and into 2024. Additionally, operating margin during the three months ended June 30, 2022 benefited from the favorable acceleration of a transmission project by the customer.
Underground Utility and Infrastructure Solutions Segment Results
Revenues. The increase in revenues for the three months ended June 30, 2023 was due to higher demand from our gas utility services customers, and to a lesser extent, increased revenues associated with large pipeline projects in Canada. These increases were partially offset by approximately $20 million as a result of unfavorable foreign currency exchange rates.
Operating Income. The increase in operating income and operating margin for the three months ended June 30, 2023March 31, 2024 was primarily due to the increase in revenues, which contributed to higher levelsfavorable impact of fixed cost absorption.
Corporate and Non-Allocated Costs
The decrease in corporate and non-allocated costs during the three months ended June 30, 2023 was primarily due to a $37.9 million decrease in intangible asset amortization, largely associated with the acquisition of Blattner, which was fully amortized by the third quarter of 2022; and an $11.9 million decrease in acquisition and integration costsmargins related to recent acquisitions. These decreases weretelecommunication projects and the overall mix of revenues, partially offset by an aggregate increasedecreased utilization of $36.8 million primarily related to deferred compensation liabilities due to market fluctuations; compensation expense, primarily related to salaries due partially to growthresources in business; and consulting fees.

Non-GAAP Financial Measures
EBITDA and Adjusted EBITDA
EBITDA and adjusted EBITDA, financial measures not recognized under GAAP, when used in connection with net income attributable to common stock, are intended to provide useful information to investors and analysts as they evaluate our performance. EBITDA is defined as earnings before interest and other financing expenses, taxes, depreciation and amortization, and adjusted EBITDA is defined as EBITDA adjusted for certain other items as described below. These measures should not be considered as an alternative to net income attributable to common stock or other financial measures of performance that are derived in accordance with GAAP. Management believes that the exclusion of these items from net income attributable to common stock enables us and our investors to more effectively evaluate our operations period over period and to identify operating trends that might not be apparent when includingdue to, among other reasons, the excluded items.variable nature of these items period over period. In addition, management believes these measures may be useful for investors in comparing our operating results with other companies that may be viewed as our peers.
As to certain of the items below, (i) non-cash stock-based compensation expense varies from period to period due to acquisition activity, changes in the estimated fair value of performance-based awards, forfeiture rates, accelerated vesting and amounts granted; (ii) acquisition and integration costs vary from period to period depending on the level and complexity of our acquisition activity; (iii) equity in (earnings) losses of non-integral unconsolidated affiliates varies from period to period depending on the activity and financial performance of such affiliates, the operations of which are not operationally integral to us; (iv) unrealized mark-to-market adjustments on investments vary from period to period based on fluctuations in the market price of such company’s common stock; (v) gains and losses on the sale of investments and businesses vary from period to period depending on activity; (vi) asset impairment charges vary from period to period depending on economic and other factors; and (vii)(v) change in fair value of contingent consideration liabilities varies from period to period depending on the performance in post-acquisition periods of certain acquired businesses and the effect of present value accretion on fair value calculations. Because EBITDA and adjusted EBITDA, as defined, exclude some, but not all, items that affect net income attributable to common stock, such measures may not be comparable to similarly titled measures of other companies. The most comparable GAAP financial measure, net income

Remaining Performance Obligations and Backlog
A performance obligation is a promise in a contract with a customer to transfer a distinct good or service. Our remaining performance obligations represent management’s estimate of consolidated revenues that are expected to be realized from the remaining portion of firm orders under fixed price contracts not yet completed or for which work has not yet begun, which includes estimated revenues attributable to consolidated joint ventures and variable interest entities, revenues from funded and unfunded portions of government contracts to the extent they are reasonably expected to be realized, and revenues from change orders and claims to the extent management believes they will be earned and are probable of collection.

We have also historically disclosed our backlog, a measure commonly used in our industry but not recognized under GAAP. We believe this measure enables management to more effectively forecast our future capital needs and results and better identify future operating trends that may not otherwise be apparent. We believe this measure is also useful for investors in forecasting our future results and comparing us to our competitors. Our remaining performance obligations are a component of backlog, which also includes estimated orders under MSAs, including estimated renewals, and certain non-fixed price contracts expected to be completed within one year.contracts. Our methodology for determining backlog may not be comparable to the methodologies used by other companies.
As of June 30, 2023March 31, 2024 and December 31, 2022,2023, MSAs accounted for 46%42% and 52%45% of our estimated 12-month backlog and 57%52% and 65%55% of our total backlog. Generally, our customers are not contractually committed to specific volumes of services under our MSAs, and most of our contracts can be terminated on short notice even if we are not in default. We determine the estimated backlog for these MSAs using recurring historical trends, factoring in seasonal demand and projected customer needs based upon ongoing communications. In addition, many of our MSAs are subject to renewal, and these potential renewals are considered in determining estimated backlog. As a result, estimates for remaining performance obligations and backlog are subject to change based on, among other things, project accelerations; project cancellations or delays, including but not limited
44

to those caused by commercial issues, regulatory requirements, natural disasters, emergencies and adverse weather conditions; and final acceptance of change orders by customers. These factors can cause revenues to be realized in periods and at levels that are different than originally projected.
The following table reconciles total remaining performance obligations to our backlog (a non-GAAP financial measure) by reportable segment along with estimates of amounts expected to be realized within 12 months (in thousands):

Liquidity and Capital Resources
Overview
We plan to fund our working capital, capital expenditures, debt service, dividends and other cash requirements with our current available liquidity and cash from operations, which could be affected by general economic, financial, competitive, legislative, regulatory, business and other factors, many of which are beyond our control. Management monitors financial markets and national and global economic conditions for factors that may affect our liquidity and capital resources.
Our capital deployment priorities that require the use of cash include: (i) working capital to fund ongoing operating needs, (ii) capital expenditures to meet anticipated demand for our services, (iii) acquisitions and investments to facilitate the long-term growth and sustainability of our business, and (iv) return of capital to stockholders, including through the payment of dividends and repurchases of our outstanding common stock. We intend to fund these requirements primarily with cash flow from operating activities, as well as debt financing as needed.
Cash Requirements and Capital Allocation
During the sixthree months ended June 30, 2023,March 31, 2024, there were no material changes outside the ordinary course of business in the specified contractual obligations or changes to our capital allocation priorities as set forth in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in Part II of the 20222023 Annual Report. We anticipate that our future cash flows from operating activities, cash and cash equivalents on hand, existing borrowing capacity under our senior
45

credit facility and commercial paper program and ability to access capital markets for additional capital will provide sufficient funds to enable us to meet our cash requirements for the next twelve months and over the longer term.

Significant Sources of Cash
Cash flow from operating activities is primarily influenced by demand for our services and operating margins but is also influenced by the timing of working capital needs associated with the various types of services that we provide. Our working capital needs may increase when we commence large volumes of work under circumstances where project costs are required to be paid before the associated receivables are billed and collected. Additionally, operating cash flows may be negatively impacted as a result of unpaid and delayed change orders and claims. Changes in project timing due to delays or accelerations and other economic, regulatory, market and political factors that may affect customer spending could also impact cash flow from operating activities. Further information with respect to our cash flow from operating activities is set forth below and in Note 16 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this Quarterly Report.
Our available commitments under our senior credit facility and cash and cash equivalents as of June 30, 2023March 31, 2024 were as follows (in thousands):

(1)    RepresentsAmount represents unsecured notes issued under our commercial paper program, which allows for the issuance of notes up tohas a maximum aggregate face amount of $1.0$1.50 billion of notes outstanding at any time. Available commitments for revolving loans under our senior credit facility must be maintained to provide credit support for notes issued under our commercial paper program, and therefore such notes effectively reduce the available borrowing capacity under our senior credit facility.
(2)    Further information with respect to our cash and cash equivalents is set forth below and in Note 15 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this Quarterly Report. This
39

amount includes $93.5$216.6 million in jurisdictions outside of the U.S., principally in Canada and Australia. There are currently no legal or economic restrictions that would materially impede our ability to repatriate such cash.
We consider our investment policies related to cash and cash equivalents to be conservative, as we maintain a diverse portfolio of what we believe to be high-quality cash and cash equivalent investments with short-term maturities. Additionally, subject to the conditions specified in the credit agreement for our senior credit facility, we have the option to increase the capacity of our senior credit facility, in the form of an increase in the revolving commitments, term loans or a combination thereof, from time to time, upon receipt of additional commitments from new or existing lenders by up to an additional (i) $400.0 million plus (ii) additional amounts so long as the Incremental Leverage Ratio Requirement (as defined in the credit agreement) is satisfied at the time of such increase. The Incremental Leverage Ratio Requirement requires, among other things, after giving pro forma effect to such increase and the use of proceeds therefrom, compliance with the credit agreement’s financial covenants as of the most recent fiscal quarter end for which financial statements were required to be delivered. Further information with respect to our debt obligations is set forth in Note 8 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this Quarterly Report.
We may also seek to access the capital markets from time to time to raise additional capital, increase liquidity as necessary, refinance or extend the term of our existing indebtedness, fund acquisitions or otherwise fund our capital needs. While our financial strategy and consistent performance have allowed us to maintain investment grade ratings, our ability to access capital markets in the future depends on a number of factors, including our financial performance and financial position, our credit ratings, industry conditions, general economic conditions, our backlog, capital expenditure commitments, market conditions and market perceptions of us and our industry.

Sources and Uses of Cash, Cash Equivalents and Restricted Cash During the SixThree Months Ended June 30,March 31, 2024 and 2023 and 2022

Operating Activities
Net cash provided by operating activities of $165.8$238.0 million and $203.8$38.4 million in the sixthree months ended June 30,March 31, 2024 and 2023 and 2022 primarily reflected earnings adjusted for non-cash items and cash provided and used by the main components of working capital: “Accounts and notes receivable,” “Contract assets,” “Prepaid expenses and other current assets,” “Accounts payable and accrued expenses,” and “Contract liabilities.” The netNet cash provided by operating activities during the six months ended June 30,March 31, 2023 and 2022 was negatively impacted by incremental working capital requirements and the timing of billings related to the large renewable transmission project in Canada and the timingas discussed further in Note 3 of the associated billings.Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this Quarterly Report.
As discussed above, cash flow provided by operating activities is primarily influenced by demand for our services and operating margins but is also influenced by working capital needs. Our working capital needs may increase when we commence large volumes of work under circumstances where project costs, primarily labor, equipment and subcontractors, are required to be paid before the associated receivables are billed and collected and when we incur costs for work that is the subject of unpaid change orders and claims. Accordingly, changes within working capital in accounts receivable, contract assets and contract liabilities are normally related and are typically affected on a collective basis by changes in revenue due to the timing and volume of work performed and variability in the timing of customer billings and payments, as well as change orders and claims. Additionally, working capital needs are generally higher during the summer and fall due to increased demand for our services when favorable weather conditions exist in many of our operating regions. Conversely, working capital assets are typically converted to cash during the winter. These seasonal trends can be offset by changes in project timing due to delays or accelerations and other economic factors that may affect customer spending, including market conditions or the impact of certain unforeseen events (e.g., regulatory and other actions that impact the supply chain for certain materials).
Days sales outstanding (DSO) represents the average number of days it takes revenues to be converted into cash, which management believes is an important metric for assessing liquidity. 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. DSO is calculated by using the sum of current accounts receivable, net of allowance (which includes retainage and unbilled balances),
40

plus contract assets, less contract liabilities, and divided by average revenues per day during the quarter. DSO as of June 30, 2023March 31, 2024 was 7871 days, which was lower than DSO of 8177 days as of June 30, 2022March 31, 2023 and lower than our five-year historical average DSO of 8283 days. This decrease in DSO as compared to June 30, 2022March 31, 2023 was partially due to an increase in contract liabilities related to favorable billing terms on certain large projects as well asand increased revenues. The favorable impact on operating cash flow related torevenues in the three months ended March 31, 2024. Although the decrease in DSO had a positive impact on cash flow from operating activities, unapproved change orders included in contract assets from the aforementioned large renewable transmission project in Canada continued to negatively impact DSO and cash flow from operating activities as of and for the three months ended March 31, 2024. Also negatively impacting cash flow from operating activities was partially offset by our prepayment of amounts to suppliers for certain project materials that require a long lead time during the three months ended March 31, 2024 and increased working capital requirements primarily related to increased unapproved change orders included in contract assets from the aforementioned2023 and payments of a significant amount of accounts payable balances on certain large renewable transmission project in Canada.projects during the three months ended March 31, 2024 that were outstanding as of December 31, 2023.
Investing Activities
Net cash used in investing activities in the sixthree months ended June 30, 2023March 31, 2024 included $452.3$384.1 million related to acquisitions and $185.6$83.1 million of capital expenditures. Partially offsetting these items were $42.3$28.7 million of proceeds from the disposition of a non-core business, $26.6 million of proceeds from the sale of a non-integral equity investmentsinvestment and $35.0$26.4 million of proceeds from the sale of, and insurance settlements related to, property and equipment.
Net cash used in investing activities in the sixthree months ended June 30, 2022March 31, 2023 included $231.5$452.3 million related to acquisitions and $80.3 million of capital expenditures and $16.7expenditures. Partially offsetting these items were $39.1 million of cash used forreceived from the sale of investments partially offset by $25.4and $10.8 million of proceeds from the sale of, and insurance settlements related to, property and equipment and $16.9 million of cash received from investments, which primarily related to proceeds received from the sale of a non-controlling ownership interest in a technology company.equipment.
Our industry is capital intensive, and we expect substantial capital expenditures and commitments for equipment purchases and equipment lease and rental arrangements to be needed for the foreseeable future in order to meet anticipated demand for our services. In addition, we expect to continue to pursue strategic acquisitions and investments, although we cannot predict the timing or amount of the cash needed for these initiatives.
47

We also have various other capital commitments that are detailed primarily in Note 14 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this Quarterly Report.
Financing Activities
Net cash used in financing activities in the three months ended March 31, 2024 included $504.5 million of net repayments under our senior credit facility and commercial paper program, $75.7 million of payments to satisfy tax withholding obligations associated with stock-based compensation and the payment of $13.7 million of dividends.
Net cash provided by financing activities in the sixthree months ended June 30,March 31, 2023 included $491.7$380.6 million of net borrowings under our senior credit facility and commercial paper program, partially offset by $110.8$108.7 million of cash payments to satisfy tax withholding obligations associated with stock-based compensation and $24.5compensation; the payment of $12.8 million of cash payments for dividends.
Net cash used in financing activities in the six months ended June 30, 2022 included $94.4 million of cash payments for common stock repurchases, $76.2 million of cash payments to satisfy tax withholding obligations associated with stock-based compensationdividends; and $20.9 million of cash payments for dividends. These items were partially offset by $142.1$8.7 million of net borrowings under our senior credit facility.distributions to non-controlling interests.
We expect to continue to utilize cash for similar financing activities in the future, including repayments underof our senior credit facility and commercial paper program,outstanding debt, payment of cash dividends and repurchases of our common stock and/or debt securities.

Critical Accounting Estimates
The discussion and analysis of our financial condition and results of operations are based on our condensed consolidated financial statements, which have been prepared in accordance with GAAP. Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with GAAP, have been condensed or omitted pursuant to those rules and regulations. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities known to exist as of the date the condensed consolidated financial statements are published and the reported amounts of revenues and expenses recognized during the periods presented. We review all significant estimates affecting our condensed consolidated financial statements on a recurring basis and record the effect of any necessary adjustments prior to their publication. Judgments and estimates are based on our beliefs and assumptions derived from information available at the time such judgments and estimates are made. Uncertainties with respect to such estimates and assumptions are inherent in the preparation of financial statements. There can be no assurance that actual results will not differ from those estimates. Management has reviewed its development and selection of critical accounting estimates with the audit committee of our Board of Directors. Our accounting policies are primarily described in NoteNotes 2 and 4 of the Notes to Consolidated Financial Statements in Item 8. Financial Statements and Supplementary Data in Part II of the 20222023 Annual Report and should be read in
41

conjunction with the accounting policies identified that we believe affect our more significant judgments and estimates detailed in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations of Part II of our 20222023 Annual Report.Report, which we believe affect our more significant estimates.

Item 3.Quantitative and Qualitative Disclosures about Market Risk.
There were no material changes to our quantitative and qualitative disclosures about market risk during the sixthree months ended June 30, 2023.March 31, 2024. Our primary exposure to market risk relates to unfavorable changes in interest rates and currency exchange rates. Refer to the information on financial market risk related to changes in interest rates and foreign currency exchange rates in Item 7A. Quantitative and Qualitative Disclosures About Market Risk of Part II of our 20222023 Annual Report.

Item 4.Controls and Procedures.
Attached as exhibits to this Quarterly Report on Form 10-Q are certifications of Quanta’s Chief Executive Officer and Chief Financial Officer that are required in accordance with Rule 13a-14 of the Securities Exchange Act of 1934, as amended (the Exchange Act). This Item 4. section includes information concerning the controls and controls evaluation referred to in the certifications, and it should be read in conjunction with the certifications for a more complete understanding of the topics presented.
Evaluation of Disclosure Controls and Procedures
Our management has established and maintains a system of disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act, such as this Quarterly Report on Form 10-Q, is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms. The disclosure controls and procedures are also designed to provide reasonable assurance that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
48

As of the end of the period covered by this Quarterly Report, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b), as such disclosure controls and procedures are defined in Rule 13a-15(e) and 15d-15(e) of the Exchange Act. This evaluation was carried out under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer. Based on this evaluation, these officers have concluded that, as of June 30, 2023,March 31, 2024, our disclosure controls and procedures were effective to provide reasonable assurance of achieving their objectives.
Evaluation of Internal Control over Financial Reporting
We acquired three businessbusinesses during the sixthree months ended June 30, 2023.March 31, 2024. We are in the process of integrating these acquired businessbusinesses into our overall internal control over financial reporting process.
Except as noted above, there has been no change in our internal control over financial reporting that occurred during the quarter ended June 30, 2023March 31, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
Design and Operation of Control Systems
Our management, including the Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and breakdowns can occur because of simple errors or mistakes. Controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

PART II — OTHER INFORMATION
Item 1.  Legal Proceedings.
We are from time to time party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, breach of contract, negligence or gross negligence and/or property damage, environmental liabilities, wage and hour claims and other employment-related damages, punitive damages, consequential damages, civil penalties or other losses, or injunctive or declaratory relief, as well as interest and attorneys’ fees associated with such claims. With respect to all such lawsuits, claims and proceedings, we record a reserve when we believe it is probable that a loss has been incurred and the amount of loss can be reasonably estimated. In addition, we disclose matters for which management believes a material loss is at least reasonably possible. See Note 14 of the Notes to Condensed Consolidated Financial Statements in Item 1. Financial Statements of Part I of this Quarterly Report, which is incorporated by reference in this Item 1, for additional information regarding litigation, claims and other legal proceedings.
Environmental Matters
Item 103 of Regulation S-K requires disclosure of certain environmental matters in which a governmental authority is a party to the proceedings and when such proceedings involve the potential for monetary sanctions that management reasonably believes will exceed a specified threshold. Pursuant to SEC regulations, we use a threshold of $1.0 million for such proceedings.

Item 1A.  Risk Factors.
Our business is subject to a variety of risks and uncertainties that are difficult to predict and many of which are outside of our control. For a detailed discussion of the risks that affect our business, refer to Item 1A. Risk Factors of Part I of our 20222023 Annual Report. As of the date of this filing, there have been no material changes to the risk factors previously described in our 20222023 Annual Report. The matters specifically identified are not the only risks and uncertainties facing our company, and risks and uncertainties not known to us or not specifically identified also may impair our business operations. If any of these risks and uncertainties occur, our business, financial condition, results of operations and cash flows could be negatively affected, which could negatively impact the value of an investment in our company.
