NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
(Unaudited)

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, 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, comprehensive income and operating cash flows for the interim periods are not necessarily indicative of the results for the entire fiscal year.

2. NEW ACCOUNTING PRONOUNCEMENTS:
Recently Adopted Guidance
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. 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 adopted this update effective January 1, 2024, and it did not 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.

3. REVENUE RECOGNITION AND RELATED BALANCE SHEET ACCOUNTS:
Contracts
Quanta’s services are generally provided pursuant to master service agreements (MSAs), repair and maintenance contracts and fixed price and non-fixed price construction contracts. These contracts are classified into three categories: unit-price contracts, cost-plus contracts and fixed price contracts.
The following tables present Quanta’s revenue disaggregated by contract type and by geographic location, as determined by the job location (in thousands):
Three Months Ended March 31,
20242023
By contract type:
Fixed price contracts$2,672,315 53.1 %$1,934,888 43.7 %
Unit-price contracts1,427,507 28.4 1,497,394 33.8 
Cost-plus contracts931,997 18.5 996,544 22.5 
Total revenues$5,031,819 100.0 %$4,428,826 100.0 %
Three Months Ended March 31,
20242023
By primary geographic location:
United States$4,569,716 90.8 %$3,666,365 82.8 %
Canada229,427 4.6 542,360 12.2 
Australia146,029 2.9 154,677 3.5 
Others86,647 1.7 65,424 1.5 
Total revenues$5,031,819 100.0 %$4,428,826 100.0 %

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 57.5% and 50.1% of Quanta’s revenues recognized during the three months ended March 31, 2024 and 2023 were associated with this revenue recognition method.
Performance Obligations
As of March 31, 2024 and December 31, 2023, the aggregate transaction price allocated to unsatisfied or partially satisfied performance obligations was approximately $14.88 billion and $13.89 billion, with 64.6% and 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.
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
12

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

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.
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 March 31, 2024 and December 31, 2023, Quanta had recognized revenues of $774.8 million and $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 March 31, 2024 and December 31, 2023 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 2023, additional costs arose from residual impacts associated with the aforementioned items, as well as work resequencing and acceleration, access delays, and logistical challenges and 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 0.1% during each of the three months ended March 31, 2024 and 2023 as a result of changes in estimates associated with performance obligations on fixed price contracts partially satisfied prior to December 31, 2023 and 2022.
Operating results for the three months ended March 31, 2024 were impacted by less than 5% of gross profit as a result of aggregate changes in contract estimates related to projects that were in progress as of December 31, 2023. However, gross profit was negatively impacted by $21.9 million as a result of decreased productivity associated with a large solar facility project in the United States.
Operating results for the three months ended March 31, 2023 were impacted by less than 5% of gross profit as a result of aggregate changes in contract estimates related to projects that were in progress as of December 31, 2022. There were no material changes in estimates on any individual project.
Contract Assets and Liabilities
Contract assets and liabilities consisted of the following (in thousands):
March 31, 2024December 31, 2023
Contract assets$1,274,686 $1,413,057 
Contract liabilities$1,443,125 $1,538,677 
Contract assets and liabilities fluctuate period to period based on various factors, including, among others, changes in the number and size of projects in progress at period end; variability in billing and payment terms, such as up-front or advance billings, interim or milestone billings, or deferred billings; and recognized unapproved change orders and contract claims. The decrease in contract assets from December 31, 2023 to March 31, 2024 was primarily due to the completion of certain large
13

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

projects and the corresponding billing of amounts previously recorded as contract assets, while the decrease in contract liabilities was primarily due to higher production on a large renewable transmission project and the associated recognition of revenue on amounts that were previously recorded as contract liabilities.
During the three months ended March 31, 2024 and 2023, Quanta recognized revenue of approximately $952.6 million and $641.1 million related to contract liabilities outstanding as of the end of each 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 with 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 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, changes 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, (e.g., inflationary pressure, supply chain and other logistical challenges and increased interest 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.
Activity in Quanta’s allowance for credit losses consisted of the following (in thousands):
 Three Months Ended
March 31,
 20242023
Balance at beginning of period$13,962 $15,644 
Increase in provision for credit losses271 2,358 
Write-offs charged against the allowance net of recoveries of amounts previously written off(278)(1,472)
Balance at end of period$13,955 $16,530 
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 for services Quanta has performed for customers. Quanta grants credit under normal payment terms, generally without collateral. As 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 10% of Quanta’s consolidated receivable position,
14

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

which includes amounts related to contracts assets. No customer represented 10% or more of Quanta’s consolidated revenues for the three months ended March 31, 2024 or 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 March 31, 2024 and December 31, 2023 were $624.2 million and $610.0 million, which are included in “Accounts receivable.” Retainage balances with expected settlement dates beyond one year were $88.4 million and $78.7 million as of March 31, 2024 and December 31, 2023 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 March 31, 2024 and December 31, 2023, unbilled receivables included in “Accounts receivable” were $794.3 million and $743.6 million. 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 $66.7 million and $58.6 million as of March 31, 2024 and December 31, 2023.

4. SEGMENT INFORMATION:
Quanta reports its results under three reportable segments described below:
Electric Power Infrastructure Solutions (Electric Power). Quanta’s Electric Power segment provides comprehensive infrastructure solutions to customers in the electric power and communications markets.
Renewable Energy Infrastructure Solutions (Renewable Energy). Quanta’s Renewable Energy segment provides comprehensive infrastructure solutions to customers that are involved in the renewable energy industry.
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) for the three months ended March 31, 2024 and 2023. Operating margin is calculated by dividing operating income (loss) by revenues. The following table

5. ACQUISITIONS:
The results of operations of acquired businesses have been included in Quanta’s consolidated financial statements since their respective acquisition dates.
In April 2024, Quanta acquired a business located in the United States that manufactures transmission and distribution equipment for the electric utility industry. The aggregate consideration paid or payable for this transaction was approximately $72 million, consisting of a combination of cash and shares of Quanta common stock. The final amount of consideration also remains subject to certain post-closing adjustments, including with respect to net working capital.
During the three months ended March 31, 2024, Quanta acquired three businesses located in the United States, including: a business that provides specialty environmental solutions to industrial and petrochemical companies (primarily included in the Underground and Infrastructure segment); a business that specializes in testing, manufacturing and distributing safety equipment and supplies (primarily included in the Electric Power and Renewable Energy segments); and a business that specializes in electrical infrastructure services for substations, data centers and governmental entities (primarily included in the Electric Power segment). The consideration for the businesses acquired during the three months ended March 31, 2024
16

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

consisted of approximately $382.9 million paid or payable in cash on the acquisition dates and 250,539 shares of Quanta common stock, which had a fair value of $51.8 million as of the acquisition dates. The final amount of consideration for these acquisitions remains subject to certain post-closing adjustments, including with respect to net working capital.
During the year ended December 31, 2023, Quanta acquired five businesses located in the United States, including: a business that provides services related to high-voltage transmission lines, overhead and underground distribution, emergency restoration and industrial and commercial wiring and lighting (primarily included in the Electric Power segment); a business that procures parts, assembles kits for sale, manages logistics and installs solar tracking equipment for utility and development customers (primarily included in the Renewable Energy segment); a business that provides concrete construction services (primarily included in the Electric Power and Renewable Energy segments); a business specializing in power studies, maintenance testing and commissioning primarily for utility and commercial customers (included in the Electric Power segment) and a business that manufactures power transformers for the electric utility, renewable energy, municipal power and industrial markets (included in the Electric Power and Renewable Energy segments). The consideration for these transactions consisted of approximately $785.7 million paid or payable in cash (subject to certain adjustments) and 1,238,576 shares of Quanta common stock, which had a fair value of $158.9 million as of the dates of the acquisitions.
Additionally, the former owners of certain acquired businesses are eligible to receive potential payments of contingent consideration to the extent the acquired businesses achieve certain financial performance targets over specified post-acquisition periods.
Purchase Price Allocation
Quanta is finalizing its purchase price allocations related to certain businesses acquired subsequent to March 31, 2023, and further adjustments to the purchase price allocations may occur, with possible updates primarily related to intangible asset values, property and equipment values, certain contingent liabilities, tax estimates, and the finalization of closing working capital adjustments. The aggregate consideration paid or payable for businesses acquired between March 31, 2023 and March 31, 2024 was allocated to acquired assets and assumed liabilities, which resulted in an allocation of $194.2 million to net tangible assets, $207.8 million to identifiable intangible assets and $403.4 million to goodwill.
The following table summarizes the estimated fair value of total consideration transferred or estimated to be transferred and the fair value of assets acquired and liabilities assumed as of their respective acquisition dates as of March 31, 2024 for

Contingent Consideration
As described above, certain business acquisitions have contingent consideration liabilities associated with the transactions. The aggregate fair value of these outstanding contingent consideration liabilities was $172.0 million and $157.1 million as of March 31, 2024 and December 31, 2023, and such amounts are included in “Insurance and other non-current liabilities.”
Quanta’s aggregate contingent consideration liabilities can change due to additional business acquisitions, settlement of outstanding liabilities, accretion in present value, changes in estimated fair value, the performance of acquired businesses in post-acquisition periods, and in certain cases, management discretion. These changes are reflected in “Change in fair value of contingent consideration liabilities” in the accompanying consolidated statements of operations.
The fair value determinations for contingent consideration liabilities incorporate significant inputs not observable in the market, including revenue forecasts, operating margins, discount rates and the probability of acquired businesses achieving certain performance targets during designated post-acquisition periods. Accordingly, the level of inputs used for these fair value measurements is Level 3.
All of Quanta’s outstanding contingent consideration liabilities are subject to a maximum payment amount, and the aggregate maximum payment amount of these liabilities totaled $352.6 million as of March 31, 2024. During the three months ended March 31, 2023, Quanta settled certain contingent consideration liabilities with cash payments of $5.0 million.
Pro Forma Results of Operations
The following unaudited supplemental pro forma results of operations for Quanta, which incorporate the acquisitions completed in the three months ended March 31, 2024 and the year ended December 31, 2023, have been provided for illustrative purposes only and may not be indicative of the actual results that would have been achieved by the combined companies for the periods presented or that may be achieved by the combined companies in the future (in thousands).

Revenues$5,033,522 $4,535,366 
Net income attributable to common stock$118,213 $86,670 
The pro forma combined results of operations for the three months ended March 31, 2024 and 2023 were prepared by adjusting the historical results of Quanta to include the historical results of the businesses acquired in 2024 as if such acquisitions had occurred January 1, 2023. The pro forma combined results of operations for the three months ended March 31, 2023 were prepared by further adjusting the historical results of Quanta to include the historical results of the business acquired in 2023 as if such acquisition had occurred January 1, 2022. These pro forma combined historical results were adjusted for the following: a reduction of interest and other financing expenses as a result of the repayment of outstanding indebtedness of the acquired businesses; an increase in interest and other financing expenses as a result of the cash consideration paid; an increase in amortization expense due to the intangible assets recorded; elimination of inter-company sales; and changes in depreciation expense to adjust acquired property and equipment to the acquisition date fair value and to conform with Quanta’s accounting policies. The pro forma combined results of operations do not include any adjustments to eliminate the impact of acquisition-related costs incurred by Quanta or any cost savings or other synergies that resulted or may result from the acquisitions.
Impact on Consolidated Results of Operations Related to Acquisitions
Included in Quanta’s condensed consolidated results of operations for the three months ended March 31, 2024 were revenues of $67.7 million and a loss before income taxes of $9.1 million, which included $4.8 million of amortization expense

During the three months ended March 31, 2024, Quanta sold a non-integral equity method investment and recognized a $12.2 million gain, $4.9 million of which was attributable to non-controlling interests. Also during the three months ended March 31, 2024, Quanta received $34.9 million in cash related to the sale of this investment, $4.9 million of which was distributed to non-controlling interests.
During the three months ended December 31, 2022, Quanta entered into an agreement to sell a non-integral equity method investment. The transaction was subject to certain customary closing conditions that were satisfied in early 2023. As a result, a $25.9 million gain was recognized in the fourth quarter of 2022, $10.4 million of which was attributable to non-controlling interests. During the year ended December 31, 2023, Quanta received $58.5 million in cash related to the sale of this investment, $9.8 million of which was distributed to non-controlling interests.
As of March 31, 2024 and December 31, 2023, Quanta had receivables of $81.4 million and $96.4 million from its integral unconsolidated affiliates and payables of $22.4 million and $24.5 million to its integral unconsolidated affiliates. Quanta recognized revenues of $59.0 million and $48.3 million during the three months ended March 31, 2024 and 2023 from services provided to its integral unconsolidated affiliates, primarily related to services provided to LUMA at cost. In addition, during the three months ended March 31, 2024 and 2023, Quanta recognized costs of sales of $88.9 million and $12.0 million for services provided to Quanta by other integral unconsolidated affiliates.
Total equity in earnings from integral unconsolidated affiliates was $12.3 million and $9.6 million for the three months ended March 31, 2024 and 2023. Total equity in earnings from non-integral unconsolidated affiliates was earnings of $3.6 million and $1.6 million for the three months ended March 31, 2024 and 2023. As of March 31, 2024, Quanta had $45.2 million of undistributed earnings related to unconsolidated affiliates.
The difference between Quanta’s carrying value and the underlying equity in the net assets of its equity investments is assigned to the assets and liabilities of the investment, giving rise to a basis difference, which was $29.9 million and $31.4 million as of March 31, 2024 and December 31, 2023. The amortization of the basis difference included in “Equity in earnings of integral unconsolidated affiliates” in the accompanying condensed consolidated statements of operations was $1.5 million and $1.8 million for the three months ended March 31, 2024 and 2023.

term loan facility and aggregate revolving commitments of $2.64 billion, with a maturity date of October 8, 2026. Borrowings under the senior credit facility and the applicable interest rates were as follows (dollars in thousands):

Weighted-average interest rate6.80 %5.99 %
As of March 31, 2024, Quanta was in compliance with all of the financial covenants under the credit agreement.
Term Loan. As of March 31, 2024, Quanta had $726.6 million outstanding under its term loan facility. The carrying amount of the term loan under Quanta’s senior credit facility approximates fair value due to its variable interest rate.
Revolving Loans. As of March 31, 2024, Quanta had $127.8 million of outstanding revolving loans under the senior credit facility, all of which were denominated in Canadian dollars. The carrying amounts of the revolving borrowings under Quanta’s senior credit facility approximate fair value, as all revolving borrowings have a variable interest rate.
As of March 31, 2024, Quanta also had $251.2 million of letters of credit issued under the senior credit facility, of which $94.6 million were denominated in U.S. dollars and $156.6 million were denominated in currencies other than the U.S. dollar, primarily Australian and Canadian dollars. Additionally, available commitments for revolving loans under the senior credit facility must be maintained in order to provide credit support for notes issued under Quanta’s commercial paper program, and therefore such notes effectively reduce the available borrowing capacity under the senior credit facility.
As of March 31, 2024, $2.05 billion remained available under the senior credit facility for new revolving loans, letters of credit and support of the commercial paper program.
Commercial Paper Program
As of March 31, 2024, Quanta had $208.4 million of outstanding unsecured notes under its commercial paper program, with a weighted average interest rate of 5.75%. The carrying amounts of the notes issued under Quanta’s commercial paper program approximate fair value, and all notes currently have a short maturity.
Borrowings under the commercial paper program and the applicable interest rates were as follows (dollars in thousands):

When these purchase options are exercised by a third-party lessor on behalf of Quanta, the transaction is deemed to be a financing transaction for accounting purposes, which results in the recognition of an asset equal to the purchase price and a corresponding liability.
(3)    Short-term lease cost includes both leases and rentals with initial terms of one year or less. Variable lease cost is insignificant.
Related party lease expense was $4.7 million and $3.9 million for the three months ended March 31, 2024 and 2023.

Future minimum lease payments for short-term leases were $26.5 million as of March 31, 2024. As of March 31, 2024, Quanta also had minimum lease payments related to operating lease obligations of $17.5 million for leases that had not yet commenced as of such date, are expected to commence in 2024 and have lease terms of one to ten years. Additionally, as described above, certain of Quanta’s equipment rental agreements contain purchase options pursuant to which the purchase price is offset by a portion of the rental payments. The future payments related to these lease financing transactions totaled $95.2 million and comprise principal and interest payments.

The weighted average remaining lease terms (other than for short-term leases) and discount rates were as follows:

Weighted average remaining lease term (in years):
Operating leases4.27
Finance leases4.96
Weighted average discount rate:

Finance leases6.3 %
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 March 31, 2024 and 2023 were a provision of 14.3% and a benefit of 3.7%. The tax rates for the three months ended March 31, 2024 and 2023 were favorably impacted by the recognition of $21.6 million and $32.0 million of benefits that resulted from equity incentive awards vesting at a higher fair market value than their grant date fair value.
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.
As of March 31, 2024, the total amount of unrecognized tax benefits relating to uncertain tax positions was $47.4 million, a net increase of $2.3 million from December 31, 2023, which resulted from positions expected to be taken in 2024. Quanta’s consolidated federal income tax returns for tax years 2017, 2018, and 2020 through 2022 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 $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:
Stock Repurchases
On May 23, 2023, Quanta’s Board of Directors approved a 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. As of March 31, 2024, $499.7 million remained available under this repurchase program.
Repurchases may be implemented through open market repurchases or privately negotiated transactions, at management’s discretion, based on market and business conditions, applicable contractual and legal requirements, including restrictions under Quanta’s senior credit facility, and other factors. Quanta is not obligated to acquire any specific amount of common stock, and the repurchase program may be modified or terminated by Quanta’s Board of Directors at any time at its sole discretion and without notice.

During the three months ended March 31, 2024 and 2023, Quanta recognized $9.6 million and $4.9 million of non-cash stock compensation expense related to PSUs to be settled in common stock. As of March 31, 2024, there was an estimated $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 2.16 years.
During the three months ended March 31, 2024 and 2023, 0.3 million and 0.7 million shares of common stock were issued in connection with earned and vested PSUs. The approximate fair values of PSUs earned and vested during the three months ended March 31, 2024 and 2023 were $75.4 million and $115.5 million, 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 March 31, 2024 and December 31, 2023, the liability related to deferred cash compensation under these plans, including amounts contributed by Quanta, was $101.8 million and $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 March 31, 2024 and December 31, 2023, the settlement and issuance of 176,305 and 174,079 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 March 31, 2024 and December 31, 2023, the fair market values were $95.7 million and $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.
Changes in the fair market value of Quanta’s COLI assets and deferred compensation liabilities largely offset and are recorded in the accompanying statements of operations as follows (in thousands):

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. 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 were 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. Final decisions with respect to the enforcement proceedings are expected later in 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 second 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 challenges to the annulment decisions, enforcement and related proceedings, the ultimate timing and conclusion with respect to collection of the amounts 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 March 31, 2024, the total amount of the receivable was not changed and is included in “Other assets, net” in the accompanying 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 March 31, 2024.
After considering, as discussed above, that the ultimate timing and conclusion with respect to collection of the full amounts 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 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.
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 March 2024 against SCE and T-Mobile USA, Inc. (T-Mobile) in the Superior Court of California, County of Orange. The lawsuits generally

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 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 March 31, 2024 and December 31, 2023, the gross amount accrued for employer’s liability, workers’ compensation, auto liability, general liability, and group health claims totaled $371.0 million and $351.7 million, of which $237.0 million and $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 March 31, 2024 and December 31, 2023 were $5.5 million and $4.9 million, of which $0.9 million and $0.3 million are included in “Prepaid expenses and other current assets” and $4.6 million and $4.6 million are included in “Other assets, net.”
Bonds
As of March 31, 2024, the total amount of the outstanding performance bonds was estimated to be approximately $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.
Capital Commitments and Other Committed Expenditures
As of March 31, 2024, Quanta had $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 primarily related to its fleet of vehicles, which have expected delivery dates during the remainder of 2024, 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

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.
