When applicable, the transaction price is allocated to performance obligations on the basis of relative standalone selling prices that is generally determined using an expected profit margin on anticipated costs related to the performance obligation. Quanta’s contracts are classified into three categories based on the methods by which transaction prices are determined and revenue is recognized: unit-price contracts, cost-plus contracts and fixed price contracts. </div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt"> The following tables present Quanta’s revenue disaggregated by contract type and by geographic location, as

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 68.8% and 62.5% of Quanta’s revenues recognized during the three months ended June 30, 2026 and 2025 were associated with this revenue recognition method, and 66.4% and 63.0% of Quanta’s revenues recognized during the six months ended June 30, 2026 and 2025 were associated with this revenue recognition method.</div><div style="margin-top:7pt;text-align:justify;text-indent:11.25pt">Performance Obligations </div><div style="text-align:justify;text-indent:24.75pt"> </div><div style="text-align:justify;text-indent:24.75pt">Quanta’s remaining performance obligations 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 and, to a lesser extent, from certain unit-price contracts with more than an insignificant amount of partially completed units. As of June 30, 2026 and December 31, 2025, Quanta’s remaining performance obligations were approximately $33.55 billion and $23.76 billion, of which (i) approximately 70% and 66% are expected to be recognized as revenue within the 12 months following June 30, 2026 and December 31, 2025, (ii) a substantial majority of the remaining balance is expected to be recognized within each of the following 24 months, and (iii) the balance is expected to be recognized thereafter. Estimates of the timing of revenue recognition of remaining performance obligations are subject to change based on, among other things, project accelerations; project cancellations or delays, including but not limited 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.</div><div style="text-align:justify;text-indent:24.75pt"> </div><div style="text-align:justify;text-indent:24.75pt">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. </div><div style="margin-top:7pt;text-align:justify;text-indent:11.25pt">Contract Estimates and Changes in Estimates</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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 </div><div style="margin-top:7pt;text-align:justify">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. </div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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.</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">As of June 30, 2026 and December 31, 2025, Quanta had recognized revenues of $411.1 million and $983.6 million related to unapproved change orders and claims included as contract price adjustments primarily in “Contract assets” in the accompanying condensed 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 decrease in the unapproved change orders and claims from December 31, 2025 to June 30, 2026 was related to approval by the customer of the balance associated with a large renewable transmission project in Canada. The project was completed in 2024. </div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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.</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">Revenues were impacted by 0.9% and 0.6% during the three months ended June 30, 2026 and 2025 as a result of changes in estimates associated with performance obligations on fixed price contracts partially satisfied prior to March 31, 2026 and 2025. Revenues were impacted by (0.5)% and a nominal amount during the six months ended June 30, 2026 and 2025 as a result of changes in estimates associated with performance obligations on fixed price contracts partially satisfied prior to December 31, 2025 and 2024. The net impacts resulted from net changes in estimates across a large number of projects, primarily as a result of favorable or unfavorable performance and changes on estimates related to mitigation of risks and contingencies as the projects progressed to completion. These changes were made in the ordinary course of business and there were no changes that resulted in material amounts that should have been recognized in a prior period. </div><div style="margin-top:7pt;text-align:justify;text-indent:11.25pt">Contract Assets and Liabilities</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">Contract assets and liabilities consisted of the following (in thousands):</div><div style="margin-top:5pt;text-align:center"><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:100.000%"><tr><td style="width:1.0%"></td><td style="width:68.490%"></td><td style="width:0.1%"></td><td style="width:0.1%"></td><td style="width:0.530%"></td><td style="width:0.1%"></td><td style="width:1.0%"></td><td style="width:13.373%"></td><td style="width:0.1%"></td><td style="width:0.1%"></td><td style="width:0.530%"></td><td style="width:0.1%"></td><td style="width:1.0%"></td><td style="width:13.377%"></td><td style="width:0.1%"></td></tr><tr><td colspan="3" style="padding:0 1pt"></td><td colspan="3" style="padding:0 1pt"></td><td colspan="3" style="padding:1.5pt 1pt;text-align:center;vertical-align:bottom">June 30, 2026</td><td colspan="3" style="padding:0 1pt"></td><td colspan="3" style="padding:1.5pt 1pt;text-align:center;vertical-align:bottom">December 31, 2025</td></tr><tr><td colspan="3" style="background-color:#cceeff;padding:1.5pt 1pt;text-align:left;vertical-align:bottom">Contract assets</td><td colspan="3" style="background-color:#cceeff;padding:0 1pt"></td><td style="background-color:#cceeff;border-top:1pt solid #000000;padding:1.5pt 0 1.5pt 1pt;text-align:left;vertical-align:bottom">$</td><td style="background-color:#cceeff;border-top:1pt solid #000000;padding:1.5pt 0;text-align:right;vertical-align:bottom">1,534,265 </td><td style="background-color:#cceeff;border-top:1pt solid #000000;padding:1.5pt 1pt 1.5pt 0;text-align:right;vertical-align:bottom"></td><td colspan="3" style="background-color:#cceeff;padding:0 1pt"></td><td style="background-color:#cceeff;border-top:1pt solid #000000;padding:1.5pt 0 1.5pt 1pt;text-align:left;vertical-align:bottom">$</td><td style="background-color:#cceeff;border-top:1pt solid #000000;padding:1.5pt 0;text-align:right;vertical-align:bottom">1,522,186 </td><td style="background-color:#cceeff;border-top:1pt solid #000000;padding:1.5pt 1pt 1.5pt 0;text-align:right;vertical-align:bottom"></td></tr><tr><td colspan="3" style="background-color:#ffffff;padding:1.5pt 1pt;text-align:left;vertical-align:bottom">Contract liabilities</td><td colspan="3" style="background-color:#ffffff;padding:0 1pt"></td><td style="background-color:#ffffff;padding:1.5pt 0 1.5pt 1pt;text-align:left;vertical-align:bottom">$</td><td style="background-color:#ffffff;padding:1.5pt 0;text-align:right;vertical-align:bottom">4,241,933 </td><td style="background-color:#ffffff;padding:1.5pt 1pt 1.5pt 0;text-align:right;vertical-align:bottom"></td><td colspan="3" style="background-color:#ffffff;padding:0 1pt"></td><td style="background-color:#ffffff;padding:1.5pt 0 1.5pt 1pt;text-align:left;vertical-align:bottom">$</td><td style="background-color:#ffffff;padding:1.5pt 0;text-align:right;vertical-align:bottom">3,258,465 </td><td style="background-color:#ffffff;padding:1.5pt 1pt 1.5pt 0;text-align:right;vertical-align:bottom"></td></tr></table></div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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; recognized unapproved change orders and contract claims; and acquisitions.

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 </div><div style="margin-top:7pt;text-align:justify">financial assets with similar risk characteristics.

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

for assessing credit loss. The second risk pool represents approximately 7% of Quanta’s consolidated financial assets as of June 30, 2026 and did not have any allowance for credit loss or experience any credit loss during the periods presented.

In addition, the customers in the second risk pool typically pre-approve invoices and often receive project financing.</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">Provision for credit losses is included in “Selling, general and administrative expenses” in the condensed consolidated statements of operations. </div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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. No customer represented 10% or more of Quanta’s consolidated revenues for the three and six months ended June 30, 2026 or 2025, and no customer represented 10% or more of Quanta’s consolidated receivable position as of June 30, 2026 or December 31, 2025.</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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, 2026 and December 31, 2025 were $1.19 billion and $994.1 million, which are included in “Accounts receivable.” Retainage balances with expected settlement dates beyond one year were $312.7 million and $228.7 million as of June 30, 2026 and December 31, 2025 and are included in “Other assets, net.” </div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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, 2026 and December 31, 2025, unbilled </div><div style="margin-top:7pt;text-align:justify">receivables included in “Accounts receivable” were $1.39 billion and $1.10 billion. 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 $243.1 million and $121.0 million as of June 30, 2026 and December 31, 2025.</div>

<div style="margin-top:7pt;text-align:justify;text-indent:11.25pt">Contracts</div>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. Contracts are combined if they are entered into at or near the same time as one another and negotiated as a group, in contemplation of one another, for a related commercial purpose. When applicable, the transaction price is allocated to performance obligations on the basis of relative standalone selling prices that is generally determined using an expected profit margin on anticipated costs related to the performance obligation. Quanta’s contracts are classified into three categories based on the methods by which transaction prices are determined and revenue is recognized: unit-price contracts, cost-plus contracts and fixed price contracts.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.<div style="text-align:justify;text-indent:24.75pt">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. </div><div style="margin-top:7pt;text-align:justify;text-indent:11.25pt">Contract Estimates and Changes in Estimates</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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 </div><div style="margin-top:7pt;text-align:justify">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. </div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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.</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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.</div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">Quanta determines its allowance for credit losses based on an estimate of expected credit losses for financial instruments, primarily accounts receivable and contract assets.

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 </div><div style="margin-top:7pt;text-align:justify">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.</div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">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).</div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">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.</div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">Accounts receivable are written-off against the allowance for credit losses if they are deemed uncollectible. </div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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, 2026 and December 31, 2025, unbilled </div><div style="margin-top:7pt;text-align:justify">receivables included in “Accounts receivable” were $1.39 billion and $1.10 billion. 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 $243.1 million and $121.0 million as of June 30, 2026 and December 31, 2025.</div>

<div style="margin-top:7pt">3. SEGMENT INFORMATION:</div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">Quanta’s operations are managed by senior executives who report to its Chief Executive Officer, the chief operating decision maker. The Chief Executive Officer uses operating income for each of Quanta’s reportable segments and considers forecast to actual variances to assess performance and when making decisions about allocating capital, craft skill labor and other resources. Quanta’s two operating segments are also its two reportable segments: (1) Electric Infrastructure Solutions (Electric) and Underground Utility and Infrastructure Solutions (Underground and Infrastructure).</div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">Segment operating expenses (excluding depreciation expense) primarily include cost of services, such as wages and benefits; subcontractor costs; materials; certain equipment rental and maintenance costs, and other direct and indirect project costs, as well as allocated segment selling, general and administrative expenses. 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. </div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">Separate measures of Quanta’s assets and cash flows by reportable segment, including capital expenditures, are not produced or utilized by the Chief Executive Officer to evaluate segment performance since certain of Quanta’s fixed assets are used on an interchangeable basis across its reportable segments. As such, for reporting purposes, total depreciation expense is determined quarterly by allocating depreciation expense at each legal entity to Quanta’s reportable segments based on the ratio of each legal entity’s revenue contribution to each of Quanta’s segments. </div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">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.</div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">The following tables show segment financial information in thousands of dollars for the periods presented.

<div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">Quanta’s operations are managed by senior executives who report to its Chief Executive Officer, the chief operating decision maker. The Chief Executive Officer uses operating income for each of Quanta’s reportable segments and considers forecast to actual variances to assess performance and when making decisions about allocating capital, craft skill labor and other resources. Quanta’s two operating segments are also its two reportable segments: (1) Electric Infrastructure Solutions (Electric) and Underground Utility and Infrastructure Solutions (Underground and Infrastructure).</div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">Segment operating expenses (excluding depreciation expense) primarily include cost of services, such as wages and benefits; subcontractor costs; materials; certain equipment rental and maintenance costs, and other direct and indirect project costs, as well as allocated segment selling, general and administrative expenses. 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. </div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">Separate measures of Quanta’s assets and cash flows by reportable segment, including capital expenditures, are not produced or utilized by the Chief Executive Officer to evaluate segment performance since certain of Quanta’s fixed assets are used on an interchangeable basis across its reportable segments. As such, for reporting purposes, total depreciation expense is determined quarterly by allocating depreciation expense at each legal entity to Quanta’s reportable segments based on the ratio of each legal entity’s revenue contribution to each of Quanta’s segments. </div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">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.</div>

ACQUISITIONS:</div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">Subsequent to June 30, 2026, Quanta completed the acquisition of a business located in the United States that is a multi-craft, heavy industrial contractor (which will primarily be included in the Underground and Infrastructure segment). The </div><div style="margin-top:7pt;text-align:justify">amount of consideration for the acquisition remains subject to certain post-closing adjustments, including with respect to net working capital (inclusive of cash) and certain assumed liabilities. </div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">During the six months ended June 30, 2026, Quanta acquired three businesses, including a business located in the United States that provides utility construction, electrical contracting, industrial and energy infrastructure, and facilities services (which is included in the Electric segment); a business located in the United States that provides a full suite of front-end services, including land services (title and right-of-way), surveying and geospatial services, and engineering design work (which is included in both the Underground Infrastructure and Electric segments); and a business located in Australia that provides turnkey engineering, fabrication and manufacturing, including transportable substation buildings and switchgear, and construction services (which is included in the Electric segment). The consideration for the transactions consisted of approximately $1.09 billion in cash, including payment for cash and cash equivalents and restricted cash of $188.4 million held by the businesses as of the acquisition dates, and 182,733 shares of Quanta common stock, which had a fair value of $128.3 million as of the respective acquisition dates. The final amount of consideration for these acquisitions remains subject to certain post-closing adjustments, including with respect to net working capital, tax estimates and other contractually agreed-upon adjustments to consideration. Additionally, pursuant to the terms of the agreements, the former owners of certain of these businesses are eligible to receive payments of contingent consideration of up to approximately $242.3 million to the extent the acquired businesses achieve certain financial and other operating performance targets during periods of up to four-years. To the extent payable, Quanta, at its sole discretion, can pay up to approximately one-seventh of certain contingent consideration amounts in Quanta common stock. </div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">On July 25, 2025, Quanta completed the acquisition of Dynamic Systems (DSI), LLC (Dynamic Systems), which provides turnkey mechanical, plumbing and process infrastructure solutions to a diversified customer base that includes technology, semiconductor, healthcare and other load center markets. Dynamic Systems is located in the United States, and its results have been primarily included in the Underground and Infrastructure segment. The consideration for the acquisition included approximately $1.26 billion in cash and 518,772 shares of Quanta common stock, which had a fair value of $218.8 million as of the acquisition date. Additionally, the former owner of Dynamic Systems is eligible for a potential contingent consideration payment of up to $216.0 million to the extent the acquired business achieves certain financial and other operating performance targets during a two-year post-acquisition period beginning in January 2026. To the extent payable, Quanta, at its sole discretion, can pay 15% of any such contingent consideration amount in Quanta common stock. </div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">During the year ended December 31, 2025, Quanta also acquired seven additional businesses, including two businesses located in the United States that specialize in civil solutions, including site clearing, earthwork, soil stabilization and infrastructure development (which have been included in the Underground and Infrastructure segment); a business located in Australia that specializes in electrical engineering and the design and manufacturing of industrial technology solutions (which has been included in both the Electric and Underground and Infrastructure segments); a business located in the United States that specializes in utility construction and related support services (which has primarily been included in the Electric segment); a business located in the United States that specializes in the design, construction and repair of overhead and underground transmission and distribution infrastructure, civil construction services related to substations as well as helicopter services for electric utility infrastructure (which has primarily been included in the Electric segment); a business located in the United States that specializes in electrical solutions including low voltage technology, testing, engineering, integration, renewable energy and electric prefabrication solutions (which has primarily been included in the Electric segment); and a business located in the United States that provides helicopter services (which has primarily been included in the Electric segment and was accounted for as an asset acquisition so is not included in the disclosures in this note). The consideration for the transactions completed in 2025, other than Dynamic Systems, and accounted for as business combinations, consisted of approximately $2.01 billion in cash and 789,824 shares of Quanta common stock, which had a fair value of $284.5 million as of the respective acquisition dates. The final amount of consideration for certain of these acquisitions remains subject to certain post-closing adjustments, including with respect to tax estimates. Additionally, pursuant to the terms of the agreements, the former owners of certain of these businesses are eligible to receive payments of contingent consideration of up to approximately $228.4 million to the extent the acquired businesses achieve certain financial and other operating performance targets over periods of up to three-years. To the extent payable, Quanta, at its sole discretion, can pay up to approximately one-fourth of certain contingent consideration amounts in Quanta common stock. </div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">The results of operations of acquired businesses have been included in Quanta’s consolidated financial statements since their respective acquisition dates. </div><div style="margin-top:7pt;text-align:justify;text-indent:11.25pt">Purchase Price Allocation</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">Quanta is finalizing its purchase price allocations, including the assignment of goodwill to its reporting units, related to certain businesses acquired subsequent to June 30, 2025, and further adjustments to the purchase price allocations may occur, </div><div style="margin-top:7pt;text-align:justify">with possible updates primarily related to intangible asset values, property and equipment values, leases, certain contingent liabilities, tax estimates, and the finalization of closing working capital adjustments and other contractually agreed-upon adjustments to consideration.

<div style="margin-top:7pt">8. INCOME TAXES:</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">Quanta’s effective tax rates for the three months ended June 30, 2026 and 2025 were 25.5% and 26.7%. The lower effective tax rate for the three months ended June 30, 2026 was primarily due to changes in the mix of earnings across the jurisdictions in which Quanta operates. </div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">Quanta’s effective tax rates for the six months ended June 30, 2026 and 2025 were 20.9% and 24.6%. The lower effective tax rate for the six months ended June 30, 2026 was primarily due to a $35.9 million increase in tax benefit from vested equity incentive awards. </div>As of June 30, 2026, the total amount of unrecognized tax benefits relating to uncertain tax positions was $82.4 million, a net increase of $8.0 million from December 31, 2025, which primarily resulted from current year positions. Quanta’s consolidated federal income tax return for tax year 2024 is currently under examination by the Internal Revenue Service (IRS), and the consolidated federal income tax returns for tax years 2022 to 2023 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.

Additionally, as of June 30, 2026 and December 31, 2025, the settlement and issuance of 108,930 and 119,208 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.</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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.

COMMITMENTS AND CONTINGENCIES:</div><div style="margin-top:7pt;text-align:justify;text-indent:11.25pt">Legal Proceedings</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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 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, 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. </div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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.</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">Silverado Wildfire Matter </div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">From 2022 to present, two of Quanta’s subsidiaries have received tenders of defense and demands for preservation of evidence from Southern California Edison Company (SCE) related to lawsuits filed 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. </div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">Quanta will continue to review additional information in connection with this matter. As of June 30, 2026, Quanta believes that to the extent its subsidiaries are determined to be liable for any damages resulting from this matter, a material loss </div><div style="margin-top:7pt;text-align:justify">is not probable. Furthermore, Quanta believes that its insurance would be applied to, and adequate to cover, any such liabilities over the deductible amount applicable to this matter.</div><div style="margin-top:7pt;text-align:justify;text-indent:11.25pt">Insurance</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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 risk through retentions and/or high deductibles, as well as, both directly and indirectly, through its wholly-owned captive insurance company. The captive insurance company reimburses all claims up to the amount of the applicable deductible of any third-party insurance programs, as well as certain additional exposure related to the general and auto liability programs, which together, in certain circumstances, can be up to $100.0 million per occurrence. As a supplement to its high-deductible primary insurance and captive programs, Quanta maintains insurance with excess insurance carriers for potential losses that exceed the amount of Quanta’s deductible and captive insurance obligations. Quanta renews its insurance policies on an annual basis, and therefore deductibles, captive insurance and/or reinsurance amounts, and levels of insurance coverage may change in future periods. In addition, insurers may cancel Quanta’s coverage or determine to exclude certain items from coverage, or Quanta may elect not to obtain certain types or levels of insurance based on the potential benefits considered relative to the cost of such insurance or increase the amounts subject to self-insurance, deductibles or retention.</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">As of June 30, 2026 and December 31, 2025, the gross amount accrued for employer’s liability, workers’ compensation, auto liability, general liability, and group health claims totaled $648.2 million and $521.4 million, of which $398.3 million and $334.6 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, 2026 and December 31, 2025 were $5.7 million and $5.8 million, of which $0.2 million and $0.2 million are included in “Prepaid expenses and other current assets” and $5.5 million and $5.6 million are included in “Other assets, net.” Losses under these insurance programs are accrued based upon Quanta’s estimate of the ultimate liability for claims reported and an estimate of claims incurred but not reported, with assistance from third-party actuaries. These insurance liabilities are difficult to assess and estimate due to unknown factors, including the severity of an injury, the extent of damage, the determination of Quanta’s liability in proportion to other parties, the number of incidents not reported and the overall claims environment. The accruals are based upon known facts and historical trends, and management believes such accruals are adequate.</div><div style="margin-top:7pt;text-align:justify;text-indent:11.25pt">Bonds and Parent Guarantees</div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">As of June 30, 2026, the total amount of the outstanding performance bonds was estimated to be approximately $21.5 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. </div><div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">Additionally, from time to time, Quanta guarantees certain obligations and liabilities of its subsidiaries that may arise in connection with, among other things, contracts with customers, equipment lease obligations, joint venture arrangements and contractor licenses. These guarantees may cover all of the subsidiary’s unperformed, undischarged and unreleased obligations and liabilities under or in connection with the relevant agreement. For example, with respect to customer contracts, a guarantee may cover a variety of obligations and liabilities arising during the ordinary course of the subsidiary’s business or operations, including, among other things, warranty and breach of contract claims, third party and environmental liabilities arising from the subsidiary’s work and for which it is responsible, liquidated damages, or indemnity claims. Quanta is not aware of any claims under any guarantees that are material. To the extent a subsidiary incurs a material obligation or liability and Quanta has guaranteed the performance or payment of such obligation or liability, the recovery by a customer or other counterparty or a third party will not be limited to the assets of the subsidiary. As a result, responsibility under the guarantee could exceed the amount recoverable from the subsidiary alone and could materially and adversely affect Quanta’s consolidated business, financial condition, results of operations and cash flows. </div><div style="margin-top:7pt;text-indent:11.25pt">Joint Venture Liabilities</div><div style="margin-top:7pt;text-align:justify;text-indent:22.5pt">Quanta is a participant in certain joint ventures, including joint venture entities that provide infrastructure-related services under specific customer contracts and partially owned entities that own, operate and/or maintain certain infrastructure assets or manufacture infrastructure components or materials. If losses are incurred by joint venture entities in which Quanta holds an interest, they are generally shared ratably based on the percentage ownership of the participants in the structures. However, in Quanta’s joint venture structures that provide infrastructure-related services, each participant is typically jointly and severally liable for all of the obligations of the joint venture entity pursuant to the contract with the customer, and therefore Quanta can be liable for full performance of the contract with the customer. Additionally, in circumstances where Quanta’s participation in a joint venture qualifies as a general partnership, Quanta can be liable for all obligations of the joint venture, including </div><div style="margin-top:7pt;text-align:justify">obligations owed to the customer or any other person or entity. Quanta is not aware of circumstances that would lead to future claims against it for material amounts in connection with these liabilities. Additionally, each joint venture participant typically agrees to indemnify the other participant for any liabilities incurred in excess of what the other participant is obligated to bear under the respective joint venture agreement or in accordance with the scope of work subcontracted to each participant. It is possible, however, that Quanta could be required to pay or perform obligations in excess of its share if another participant is unable or refuses to pay or perform its share of the obligations. Quanta is not aware of circumstances that would lead to future claims against it for material amounts that would not be indemnified. However, to the extent any such claims arise, they could be material and could adversely affect Quanta’s consolidated business, financial condition, results of operations and cash flows.</div>

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. <div style="margin-top:7pt;text-align:justify;text-indent:24.75pt">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.

Cash and cash equivalents held by joint ventures, which are either consolidated or proportionately consolidated, are available to support joint venture operations, but Quanta cannot utilize those assets to support its other operations. Quanta generally has no right to cash and cash equivalents held by a joint venture other than participating in distributions, to the extent made, and in the event of dissolution. Cash and cash equivalents held by Quanta’s wholly-owned captive insurance company are generally not available for use in support of its other operations.

Amounts related to cash and cash equivalents held by consolidated or proportionately consolidated joint ventures and the captive insurance company, which are included in Quanta’s total cash and cash equivalents balances, were as follows (in thousands):<div style="margin-top:12pt;text-align:center"><table
