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:** 

***New Accounting Pronouncements and Disclosure Rules Not Yet Adopted***

In November 2024, the FASB issued an update that requires incremental disclosures about specific expense categories. Entities are required to disclose in the notes to financial statements the amounts of purchases of inventory, employee compensation, depreciation, intangible asset amortization and selling expense included in each relevant expense caption of the statements of operations. The standard also requires disclosure of the amount, and a qualitative description of, other items remaining in relevant expense captions that are not separately disaggregated. This update is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption and both prospective and retrospective application are permitted. Quanta is currently assessing the effect of this update.

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.

**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. 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: 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. Approximately 62.5% and 58.2% of Quanta's revenues recognized during the three months ended June 30, 2025 and 2024 were associated with this revenue recognition method, and 63.0% and 58.0% of Quanta's revenues recognized during the six months ended June 30, 2025 and 2024 were associated with this revenue recognition method.

***Performance Obligations***

As of June 30, 2025 and December 31, 2024, the aggregate transaction price allocated to unsatisfied or partially satisfied performance obligations was approximately $19.16 billion and $16.76 billion, with 63.4% and 67.1% 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 and, to a lesser extent, from certain unit-price contracts with more than an insignificant amount of partially completed units. 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 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 June 30, 2025 and December 31, 2024, Quanta had recognized revenues of $774.5 million and $733.6 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 revenues recognized related to unapproved change orders and claims as of June 30, 2025 and December 31, 2024 is associated with a large renewable transmission project in Canada. During the course of construction, the project experienced decreased productivity and additional costs from delays, administrative requirements and labor issues due to the COVID-19 pandemic, including incremental governmental requirements and worksite restrictions, as well as work resequencing and acceleration, access delays, and logistical challenges and other issues outside of Quanta's control. The project was completed in 2024.

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 0.6% and 0.4% during the three months ended June 30, 2025 and 2024 as a result of changes in estimates associated with performance obligations on fixed price contracts partially satisfied prior to March 31, 2025 and 2024. Revenues were positively impacted by a nominal amount and 0.2% during the six months ended June 30, 2025 and 2024 as a result of changes in estimates associated with performance obligations on fixed price contracts partially satisfied prior to December 31, 2024 and 2023. 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.

***Contract Assets and Liabilities***

Contract assets and liabilities consisted of the following (in thousands):

---

| | | |
|:---|:---|:---|
| | **June 30, 2025** | **December 31, 2024** |
| Contract assets | $1347057 | $1208619 |
| Contract liabilities | $2139490 | $2149328 |

---

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.

During the six months ended June 30, 2025 and 2024, Quanta recognized revenue of approximately $1.69 billion and $1.24 billion 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):

The above activity relates to the largest risk pool Quanta utilizes for assessing credit loss. The second risk pool represents approximately 10% of Quanta's consolidated financial instruments as of June 30, 2025 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 condensed 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. No customer represented 10% or more of Quanta's consolidated revenues for the three or six months ended June 30, 2025 or 2024, and no customer represented 10% or more of Quanta's consolidated receivable position as of June 30, 2025 or December 31, 2024.

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, 2025 and December 31, 2024 were $763.0 million and $666.5 million, which are included in "Accounts receivable." Retainage balances with expected settlement dates beyond one year were $149.8 million and $143.6 million as of June 30, 2025 and December 31, 2024 and are included in "Other assets, net."

Quanta recognizes unbilled receivables for non-fixed price contracts within "Accounts receivable" in certain circumstances, such as when revenues have been earned and recorded but the amount cannot be billed under the terms of the contract until a later date or when amounts arise from routine lags in billing. These balances do not include revenues recognized for work performed under fixed-price contracts and unit-price contracts with more than an insignificant amount of partially completed units, as these amounts are recorded as "Contract assets." As of June 30, 2025 and December 31, 2024, unbilled receivables included in "Accounts receivable" were $996.5 million and $859.9 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 $92.1 million and $97.9 million as of June 30, 2025 and December 31, 2024.

**4. SEGMENT INFORMATION:**

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.

During the three months ending March 31, 2025, Quanta's Chief Executive Officer reevaluated how performance of the business is assessed and how resources are allocated, which resulted in a change in the reporting of management's internal financial information. As a result, beginning with the three months ended March 31, 2025, Quanta began reporting the results of its two operating segments, which are also its two reportable segments: (1) Electric Infrastructure Solutions (Electric) and (2) Underground Utility and Infrastructure Solutions (Underground and Infrastructure). The Electric segment consists of the historical Electric Power Infrastructure Solutions and the Renewable Energy Infrastructure Solutions segments. In conjunction with this change, certain prior period amounts have been recast to conform to this new segment reporting structure.

*Electric*. Quanta's Electric segment provides comprehensive services for the electric power, renewable energy, technology and communications markets. Services include, but are not limited to, the design, procurement, new construction, upgrade and repair and maintenance services for electric power transmission and distribution infrastructure, both overhead and underground, and substation facilities, along with other engineering and technical services, including services that support the implementation of upgrades by utilities to modernize and harden the electric power grid in order to ensure its safety and enhance reliability, to interconnect and transmit electricity from renewable energy generation and battery storage facilities and to accommodate increased residential and commercial use of electric vehicles. In addition, this segment provides engineering, procurement, new construction, repowering and repair and maintenance services for power generation facilities, such as utility-scale wind, solar and hydropower generation facilities and battery storage facilities, as well as emergency restoration services, including the repair of infrastructure damaged by fire and inclement weather and the installation of "smart grid" technologies on electric power networks. This segment also provides comprehensive design and construction solutions to wireline and wireless communications companies; electrical systems for technology, commercial and industrial facilities and other load centers, commercial and industrial facilities; and cable multi-system operators and other customers within the communications industry, as well as other related services. Additionally, this segment manufactures power transformers and components for the electric utility, renewable energy, municipal power and industrial markets.

*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. Services include, but are not limited to design, engineering, procurement, new construction, upgrade and repair and maintenance services for natural gas systems for gas utility customers; pipeline construction, protection, integrity testing, rehabilitation and replacement services; and civil solutions. Additionally, Quanta serves the midstream and downstream industrial energy markets through catalyst replacement services, high-pressure and critical-path turnaround services, instrumentation and electrical services, piping, fabrication and storage tank services.

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.

Segment operating expenses (excluding depreciation expense) primarily includes 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.

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.

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.

Corporate and Non-Allocated Costs for the six months ended June 30, 2025 and 2024 included amortization expense of $222.7 million and $156.7 million and non-cash stock-based compensation of $82.2 million and $72.6 million.

<sup>(2)&nbsp;&nbsp;&nbsp;&nbsp;</sup>Included in operating expenses (excluding segment depreciation expense) for the Underground and Infrastructure segment during the six months ended June 30, 2024 were losses of $11.2 million related to the disposition of a non-core business.

**5. ACQUISITIONS:**

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 will primarily be included in the Underground and Infrastructure segment. The upfront consideration, subject to certain adjustments, was approximately $1.35 billion, consisting of cash and approximately $200 million of Quanta common stock. Additionally, the former owner of Dynamic Systems is eligible for a potential contingent consideration payment of up to $216.0 million to the extent certain financial performance targets are achieved by Dynamic Systems during a two-year post-acquisition period beginning in January 2026. The final 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. Additionally, Quanta is in the process of performing procedures to determine the consideration and fair value of assets acquired and liabilities assumed related to the acquisition of Dynamic Systems, including the fair value assessment of contingent consideration.

During the six months ended June 30, 2025, Quanta acquired four businesses, including two businesses located in the United States that specialize in civil solutions, including site clearing, earthwork, soil stabilization and infrastructure development (which will be included in Underground and Infrastructure segment), a business located in Australia that specializes in electrical engineering and the design and manufacturing of industrial technology solutions (which will be included in both the Electric and Underground and Infrastructure segments), and a business located in the United States that specializes in utility construction and related support services (which will primarily be included in the Electric segment). The consideration for these transactions consisted of approximately $599.3 million in cash on the dates of the acquisitions and 515,822 shares of Quanta common stock, which had a fair value of $161.6 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 $127.9 million to the extent the acquired businesses achieve certain financial and operating performance targets over a three-year period. As of the dates of the respective acquisitions, the fair value of the contingent consideration liabilities related to certain of these acquisitions was $54.9 million.

On July 17, 2024, Quanta completed the acquisition of Cupertino Electric, Inc. (CEI), which provides electrical infrastructure solutions, including engineering, procurement, project management, construction and modularization services, to the technology, renewable energy and infrastructure and commercial industries. CEI is located in the United States, and its

results have been included in the Electric segment since the acquisition date. The aggregate consideration for the acquisition was approximately $2.04 billion, which included approximately $1.65 billion in cash, including payment for cash held by CEI as of the acquisition date, and 882,926 shares of Quanta common stock, which had a fair value of $216.3 million as of the acquisition date. The cash consideration paid by Quanta, net of cash received from CEI, was $1.24 billion. Additionally, the former equity holders and award holders of CEI are eligible for a contingent consideration payment of up to $200.0 million based on achievement of certain financial performance targets during the three-year post-acquisition period beginning in January 2025. To the extent payable, Quanta, at its sole discretion, can pay up to 10% of any such contingent consideration amount in Quanta common stock. As of the acquisition date, the fair value of the contingent consideration liability was $164.0 million.

During the year ended December 31, 2024, Quanta also acquired seven additional businesses located in the United States, including: a business that provides specialty environmental solutions to utility, 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 segment); a business that specializes in electrical infrastructure services for substations, data centers and governmental entities (primarily included in the Electric segment); a business that manufactures transmission and distribution equipment for the electric utility industry (primarily included in the Electric segment); a business that provides services and equipment related to aerial telecommunications infrastructure and networks (primarily included in the Electric segment); a business that provides services related to fiber optic networks (primarily included in the Electric segment); and a business that specializes in designing, manufacturing, and distributing liquid-filled power transformers primarily for electrical companies and utilities (primarily included in the Electric segment). The consideration for these businesses consisted of approximately $540.9 million in cash and 334,472 shares of Quanta common stock, which had a fair value of $74.8 million as of the acquisition dates. As of the dates of the respective acquisitions, the fair value of the contingent consideration liabilities related to certain of these acquisitions was $24.3 million.

The results of operations of acquired businesses have been included in Quanta's consolidated financial statements since their respective acquisition dates. 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 June 30, 2024, 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 and other contractually agreed-upon adjustments to consideration. The aggregate consideration for businesses acquired between June 30, 2024 and June 30, 2025 was allocated to acquired assets and assumed liabilities, which resulted in an allocation of $605.7 million to net tangible assets, $985.7 million to identifiable intangible assets and $1.36 billion 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 June 30, 2025 for

Goodwill represents the amount by which the purchase price for an acquired business exceeds the net fair value of the identifiable assets acquired and liabilities assumed. The acquisitions completed during the six months ended June 30, 2025 contributed to the recognition of goodwill by strategically expanding Quanta's Electric and Underground and Infrastructure segments, primarily in the U.S. As of June 30, 2025, approximately $323.2 million of goodwill is expected to be deductible for income tax purposes related to acquisitions completed in the six months ended June 30, 2025.

Quanta's identifiable intangible assets subject to amortization include customer relationships, backlog, trade names, non-compete agreements, and patented rights and other. The following table summarizes the estimated fair values of identifiable intangible assets for the acquisitions completed in the six months ended June 30, 2025 as of the acquisition dates and the related weighted average amortization periods by type (in thousands, except for weighted average amortization periods, which are in years).&nbsp;&nbsp;&nbsp;&nbsp;

***Contingent Consideration***

As described above, certain business acquisitions have contingent consideration liabilities associated with the transactions. The aggregate fair value of outstanding contingent consideration liabilities for acquisitions completed prior to June 30, 2025 and their classification in the accompanying condensed consolidated balance sheets is as follows (in thousands):

---

| | | |
|:---|:---|:---|
| | **June 30, 2025** | **December 31, 2024** |

| Insurance and other non-current liabilities | 251948 | 192954 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total contingent consideration liabilities | $256202 | $344984 |

---

The estimated fair values of these contingent consideration liabilities are measured on a recurring basis using a probability-weighted discounted cash flow method, which considers significant inputs not observable in the market and are Level 3 inputs.

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, the incremental impact on Quanta's performance attributable to an acquired business and in certain cases, management discretion. These changes are reflected in "Change in fair value of contingent consideration liabilities" in the accompanying condensed consolidated statements of operations.

All of Quanta's outstanding contingent consideration liabilities are each subject to a maximum payment amount, and the aggregate maximum payment amount of these liabilities for acquisitions completed prior to June 30, 2025 totaled $396.9 million as of June 30, 2025. During the six months ended June 30, 2025, Quanta made cash payments of $106.8 million and issued 158,040 shares of its common stock to settle contingent consideration liabilities. During the six months ended June 30, 2024, Quanta did not settle any contingent consideration liabilities.

---

As of June 30, 2025, Quanta was in compliance with all of the financial covenants under the credit agreement.

*Term Loan.* As of June 30, 2025, Quanta had $693.8 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. The maturity date for the term loan facility is October 8, 2026.

*Revolving Loans.* As of June 30, 2025, Quanta had no outstanding revolving loans under the senior credit facility.

*Letters of Credit.* As of June 30, 2025, Quanta had $69.1 million of letters of credit issued under the senior credit facility, of which $68.7 million were denominated in U.S. dollars and $0.4 million were denominated primarily in Canadian and Australian 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 June 30, 2025, $2.13 billion remained available under the senior credit facility for new revolving loans, letters of credit and support of the commercial paper program.

Subsequent to June 30, 2025, Quanta extended the maturity date for revolving loans under the credit agreement for its senior credit facility from July 31, 2029 to July 31, 2030.

***Commercial Paper Program***

As of June 30, 2025, Quanta had $600.0 million of outstanding unsecured notes under its commercial paper program, with a weighted average interest rate of 4.75%.

On July 25, 2025, Quanta utilized $700.0 million of borrowings under its commercial paper program and availability under its revolving credit facility to finance the cash portion of the acquisition of Dynamic Systems.

***Additional Letters of Credit***

As of June 30, 2025, Quanta had $669.2 million of letters of credit issued outside of its senior credit facility, which were denominated in U.S. dollars.

**9. INCOME TAXES:**

Quanta's effective tax rates for the three months ended June 30, 2025 and 2024 were 26.7% and 28.2%. The lower effective tax rate for the three months ended June 30, 2025 was primarily due to the recognition, as a component of Quanta's annual effective tax rate, of certain tax credits generated during the year ended December 31, 2025.

Quanta's effective tax rates for the six months ended June 30, 2025 and 2024 were 24.6% and 23.2%. The higher effective tax rate for the six months ended June 30, 2025 was primarily due to a lower tax benefit from vested equity incentive awards. This benefit impacted the effective tax rate for the six months ended June 30, 2025 by $14.7 million, compared to $22.4 million for the six months ended June 30, 2024.

Quanta regularly evaluates valuation allowances established for deferred tax assets (DTAs) 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 DTAs is dependent upon the generation of future taxable income in the jurisdiction of the DTAs 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 DTAs to the extent estimated.

As of June 30, 2025, the total amount of unrecognized tax benefits relating to uncertain tax positions was $81.6 million, a net increase of $7.5 million from December 31, 2024, which resulted from positions expected to be taken in 2025. Quanta's consolidated federal income tax returns for tax years 2017, 2018, and 2021 through 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. Quanta believes it is reasonably possible that within the next 12 months unrecognized tax benefits may decrease by up to $13.4 million as a result of settlement of these examinations or as a result of the expiration of certain statute of limitations periods.

On July 4, 2025, the U.S. government enacted new tax legislation pursuant to Public Law No: 119-21 (also known as One Big Beautiful Bill). Since this legislation was enacted subsequent to June 30, 2025, the impact of any changes resulting from the legislation were not reflected in Quanta's condensed consolidated financial statements as of and for the three and six months ended June 30, 2025. Quanta is currently evaluating the provisions of the legislation to assess the potential impact on the effective tax rate, deferred tax assets and liabilities, and future cash tax obligations. While Quanta's preliminary analysis does not indicate a material impact, the ultimate effect will depend on a number of factors, including the issuance of regulatory guidance and further interpretation of the legislation. Quanta will continue to monitor developments and will recognize any required adjustments in the period in which the analysis is complete and the impacts can be quantified with reasonable certainty.

**10. 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. During the three months ended June 30, 2025, Quanta repurchased 67,172 shares of its common stock in the open market under its stock repurchase program for $16.0 million. During the six months ended June 30, 2025, Quanta repurchased 538,559 shares of its common stock in the open market under its stock repurchase program for $134.6 million. As of June 30, 2025, $365.1 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 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.

---

<sup>(1)&nbsp;&nbsp;&nbsp;&nbsp;</sup>The expected volatility inputs for Quanta are based on historical volatility, which is based on Quanta's dividend-adjusted closing prices over a period equivalent to the performance period.

During the six months ended June 30, 2025 and 2024, Quanta recognized $15.5 million and $19.3 million of non-cash stock compensation expense related to PSUs to be settled in common stock.

As of June 30, 2025, there was an estimated $44.5 million of total unrecognized compensation expense related to unearned and unvested PSUs. This amount is based on forecasted attainment of performance metrics and estimated forfeitures of unearned and unvested PSUs. The compensation expense related to outstanding PSUs can vary from period to period based on changes in forecasted achievement of established performance goals and the total number of shares of common stock that Quanta anticipates will be issued upon vesting of such PSUs. This cost is expected to be recognized over a weighted average period of 1.87 years.

During each of the six months ended June 30, 2025 and 2024, 0.3 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 six months ended June 30, 2025 and 2024 were $83.9 million and $75.4 million.

**12. EMPLOYEE BENEFIT PLANS:**

***Deferred Compensation Plans***

Quanta maintains non-qualified deferred compensation plans under which eligible directors and key employees may defer their receipt of certain cash compensation and/or the settlement of certain stock-based awards. As of June 30, 2025 and December 31, 2024, the liability related to deferred cash compensation under these plans, including amounts contributed by Quanta, was $119.3 million and $110.2 million, the majority of which was included in "Insurance and other non-current liabilities" in the accompanying condensed consolidated balance sheets. Additionally, as of June 30, 2025 and December 31, 2024, the settlement and issuance of 137,589 and 154,991 shares of common stock underlying certain stock-based awards had been deferred under these plans, and such issuances are scheduled to occur in future periods.

To provide for future obligations related to deferred cash compensation under these plans, Quanta has invested in corporate-owned life insurance (COLI) policies covering certain participants in the deferred compensation plans, the underlying investments of which are intended to be aligned with the investment alternatives elected by plan participants. The COLI assets are recorded at their cash surrender value, which is considered their fair market value, and as of June 30, 2025 and December 31, 2024, the fair market values were $113.0 million and $102.7 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.

**13. 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 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.

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.

*Silverado Wildfire Matter* 

From 2022 to present, 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 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

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

**(Unaudited)**

this matter as litigation and resolution efforts progress, and any such information may potentially allow Quanta to determine an estimate of potential loss, if any. As of June 30, 2025, 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 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 $70.0 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.

As of June 30, 2025 and December 31, 2024, the gross amount accrued for employer's liability, workers' compensation, auto liability, general liability, and group health claims totaled $448.9 million and $400.2 million, of which $293.2 million and $263.3 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, 2025 and December 31, 2024 were $4.2 million and $4.9 million, of which $0.2 million and $0.8 million are included in "Prepaid expenses and other current assets" and $4.0 million and $4.1 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.

***Bonds***

As of June 30, 2025, the total amount of the outstanding performance bonds was estimated to be approximately $11.7 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.

 **14. DETAIL OF CERTAIN ACCOUNTS:**

***Cash and Cash Equivalents***

As of June 30, 2025 and December 31, 2024, cash equivalents were $306.2 million and $347.5 million and consisted primarily of money market investments, money market mutual funds and short-term deposits.

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

**Item 2. *Management's Discussion and Analysis of Financial Condition and Results of Operations***

**General**

The following discussion and analysis of the financial condition and results of operations of Quanta Services, Inc. (together with its subsidiaries, Quanta, we, us or our) should be read in conjunction with our condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report and with our 2024 Annual Report, which was filed with the SEC on February 20, 2025 and is available on the SEC's website at <u>www.sec.gov</u> and on our website at <u>www.quantaservices.com</u>. The discussion below contains forward-looking statements that are based upon our current expectations and are subject to uncertainty and changes in circumstances. Actual results may differ materially from these expectations due to inaccurate assumptions and known or unknown risks and uncertainties, including those identified in *Cautionary Statement About Forward-Looking Statements and Information* above, in Item 1A. *Risk Factors* of Part II of this Quarterly Report and in Item 1A. *Risk Factors* in Part I of our 2024 Annual Report.

During the three months ending March 31, 2025, our Chief Executive Officer reevaluated how performance of the business is assessed and how resources are allocated, which resulted in a change in the reporting of management's internal financial information. As a result, beginning with the three months ended March 31, 2025, we began reporting the results of our two operating segments, which are also our two reportable segments: (1) Electric Infrastructure Solutions (Electric) and (2) Underground Utility and Infrastructure Solutions (Underground and Infrastructure). The Electric segment consists of the historical Electric Power Infrastructure Solutions and the Renewable Energy Infrastructure Solutions segments. In conjunction with this change, certain prior period amounts have been recast to conform to this new segment reporting structure.

**Overview** 

Our second quarter 2025 results reflect increased demand for our services, as consolidated revenues and operating income increased as compared to the second quarter of 2024, due to increased revenues and operating income for both our Electric and Underground and Infrastructure segments.

With respect to our Electric segment, utilities are continuing to invest significant capital in their electric power delivery systems through multi-year grid modernization and reliability programs, as well as system upgrades and hardening programs in response to recurring severe weather events. We have also experienced high demand for new and expanded transmission, substation and distribution infrastructure needed to reliably transport power. In particular, we continue to experience strong demand from our utility customers, which we believe is driven by increasing demand for electricity associated with, among other things, data centers and other technology-related dynamics, domestic manufacturing reshoring initiatives and overall electrification trends. Our acquisition of Cupertino Electric Inc. (CEI) during 2024 also resulted in increased services for our critical path electrical design and installation solutions from the technology and data center industry, as well as our utility scale solar and battery storage solutions. The cost-effectiveness of solar, wind energy and battery storage, combined with a meaningful increase in current and forecasted electricity demand is continuing to drive demand for renewable generation and related infrastructure (e.g., high-voltage electric transmission and substation infrastructure and battery storage), as well as interconnection services necessary to connect and transmit renewable-generated electricity to existing electric power delivery systems. Despite these positive longer-term trends, in the past, supply chain challenges, policy and regulatory uncertainty and other factors have resulted in project delays and increased project costs and could negatively impact future periods.

With respect to our Underground and Infrastructure segment, we continue to believe the market for our industrial solutions and gas utility and pipeline integrity services remains solid given the recurring critical-path maintenance requirements and regulated spend dedicated to modernizing systems, reducing methane emissions, ensuring environmental compliance and improving safety and reliability. However, revenues associated with large pipeline projects have fluctuated in recent years, and we anticipate that revenues associated with these projects will continue to fluctuate.

During the six months ended June 30, 2025, increased revenues and operating income contributed to $538.9 million of net cash provided by operating activities, which was a 14% decrease compared to the six months ended June 30, 2024. This cash provided by operating activities, along with borrowings under our commercial paper program, allowed us to execute our business plan, including the strategic acquisitions of certain businesses and investments in unconsolidated affiliates, for which we utilized $734.4 million of cash; repurchases of $134.6 million of common stock, and payments of $30.3 million in dividends associated with our common stock. Additionally, as of June 30, 2025, available commitments under our senior credit facility, combined with our cash and cash equivalents, totaled $2.64 billion.

In July 2025, we acquired 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. The upfront consideration, subject to certain adjustments, was approximately $1.35 billion, consisting of cash and approximately $200 million of Quanta common stock. Additionally, as further described in Note 5 of the Notes to Condensed Consolidated Financial Statements in Item 1. *Financial Statements* of Part I of this Quarterly

------

Report, there is also a potential earnout payment of up to $216.0 million associated with this acquisition. Also in July 2025, we utilized approximately $700.0 million of borrowings under our commercial paper program and availability under our revolving credit facility to finance the cash portion of the acquisition of Dynamic Systems. See Note 8 of the Notes to Condensed Consolidated Financial Statements in Item 1. *Financial Statements* of Part I of this Quarterly Report.

We expect the strong demand for our services will continue. Our remaining performance obligations and backlog were $19.16 billion and $35.84 billion as of June 30, 2025, representing increases of 14.3% and 3.8% relative to December 31, 2024. For a reconciliation of backlog to remaining performance obligations, the most comparable financial measure prepared in conformity with generally accepted accounting principles in the United States (GAAP), see *Non-GAAP Financial Measures* below.

**Significant Factors Impacting Results**

Our revenues, profit, margins and other results of operations can be influenced by a variety of factors in any given period, including those described in Item 1. *Business* and Item 1A. *Risk Factors* of Part I in our 2024 Annual Report, and those factors have caused fluctuations in our results in the past and are expected to cause fluctuations in our results in the future. Additional information with respect to certain of those factors is provided below.

*Seasonality.* Typically, our revenues are lowest in the first quarter of the year because cold, snowy or wet conditions can create challenging working environments that are more costly for our customers or cause delays on projects. In addition, infrastructure projects often do not begin in a meaningful way until our customers finalize their capital budgets, which typically occurs during the first quarter. Second quarter revenues are typically higher than those in the first quarter, as some projects begin, but continued cold and wet weather can often impact productivity. Third and fourth quarter revenues are typically the highest of the year, as a greater number of projects are underway and operating conditions, including weather, are normally more accommodating. During the fourth quarter projects are often completed and customers often seek to spend their capital budgets before year end. However, the holiday season and inclement weather can sometimes cause delays during the fourth quarter, reducing revenues and increasing costs. These seasonal impacts are typical for our U.S. operations, but seasonality for our international operations may differ. For example, revenues for certain projects in Canada are typically higher in the first quarter because projects are often accelerated in order to complete work while the ground is frozen and prior to the break up, or seasonal thaw, as productivity is adversely affected by wet ground conditions during warmer months.

*Weather, natural disasters and emergencies.* The results of our business in a given period can be impacted by adverse weather conditions, severe weather events, natural disasters or other emergencies, which include, among other things, heavy or prolonged snowfall or rainfall, hurricanes, tropical storms, tornadoes, floods, blizzards, extreme temperatures, wildfires, post-wildfire floods and debris flows, pandemics and earthquakes. Climate change has the potential to increase the frequency and extremity of severe weather events. These conditions and events can negatively impact our financial results due to, among other things, the termination, deferral or delay of projects, reduced productivity and exposure to significant liabilities due to failure of electrical power or other infrastructure on which we have performed services. However, severe weather events can also increase our emergency restoration services, which typically yield higher margins due in part to higher equipment utilization and absorption of fixed costs.

*Demand for services*. We perform the majority of our services under existing contracts, including MSAs and similar agreements pursuant to which our customers are not committed to specific volumes of our services. Therefore our volume of business can be positively or negatively affected by fluctuations in the amount of work our customers assign us in a given period, which may vary by geographic region. Examples of items that may cause demand for our services to fluctuate materially from quarter to quarter include: the financial condition of our customers, their capital spending and their access to and cost of capital; acceleration of any projects or programs by customers (e.g., modernization or hardening programs); economic and political conditions on a regional, national or global scale, including availability of renewable energy tax credits; interest rates; governmental regulations affecting the sourcing and costs of materials and equipment; other changes in U.S. and global trade relationships (e.g., tariffs, taxes); and project deferrals and cancellations.

*Revenue mix and impact on margins.* The mix of revenues based on the types of services we provide in a given period will impact margins, as certain industries and services provide higher-margin opportunities. Our larger or more complex projects typically include, among others, transmission projects with higher voltage capacities; pipeline projects with larger-diameter throughput capacities; large-scale renewable generation projects; complex data center projects; and projects with increased engineering, design or construction complexities, more difficult terrain or geographical requirements, or longer distance requirements. These projects typically yield opportunities for higher margins than our recurring services under MSAs described above, as we assume a greater degree of performance risk and there is greater utilization of our resources for longer construction timeframes. However, larger projects are subject to additional risk of regulatory delay and cyclicality. Project schedules also fluctuate, particularly in connection with larger, more complex or longer-term projects, which can affect the

------

amount of work performed in a given period. Furthermore, smaller or less complex projects typically have a greater number of companies competing for them, and competitors at times may more aggressively pursue available work. A greater percentage of smaller scale or less complex work also could negatively impact margins due to the inefficiency of transitioning between a greater number of smaller projects versus continuous production on fewer larger projects. As a result, at times we may choose to maintain a portion of our workforce and equipment in an underutilized capacity to ensure we are strategically positioned to deliver on larger projects when they move forward.

*Project variability and performance.* Margins for a single project may fluctuate period to period due to changes in the volume or type of work performed, the pricing structure under the project contract or job productivity. Additionally, our productivity and performance on a project can vary period to period based on a number of factors, including unexpected project difficulties or site conditions (including in connection with difficult geographic characteristics); project location, including locations with challenging operating conditions; whether the work is on an open or encumbered right of way; inclement weather or severe weather events; environmental restrictions or regulatory delays; protests, public activism, other political activity or legal challenges related to a project; and the performance of third parties. Moreover, we currently generate a significant portion of our revenues under fixed price contracts, and fixed price contracts are more common in connection with our larger and more complex projects that typically involve greater performance risk. Under these contracts, we assume risks related to project estimates and execution, and project revenues can vary, sometimes substantially, from our original projections due to a variety of factors, including the additional complexity, timing uncertainty or extended bidding, regulatory and permitting processes associated with these projects. These variations can result in a reduction in expected profit, the incurrence of losses on a project or the issuance of change orders and/or assertion of contract claims against customers. See *Contract Estimates and Changes in Estimates* in Note 3 of the Notes to Condensed Consolidated Financial Statements in Item 1. *Financial Statements* of Part I of this Quarterly Report.

*Subcontract work and provision of materials.* Work that is subcontracted to other service providers generally yields lower margins, and therefore an increase in subcontract work in a given period can decrease operating margins. In recent years, we have subcontracted approximately 20% of our work to other service providers. Additionally, under certain contracts, including contracts for engineering, procurement and construction services, we agree to procure all or part of the required materials. While we attempt to structure our agreements with customers and suppliers to account for the impact of increased materials procurement requirements or fluctuations in the cost of materials we procure, our margins may be lower on projects where we furnish a significant amount of materials, as our markup on materials is generally lower than our markup on labor costs, and in a given period an increase in the percentage of work with greater materials procurement requirements may decrease our overall margins, including in some cases our assuming price risk. Furthermore, fluctuations in the price or availability of materials, equipment and consumables that we or our customers utilize could impact costs to complete projects.

---

*Revenues.* Revenues increased due to a $971.2 million increase in revenues from our Electric segment and a $207.4 million increase in revenues from our Underground and Infrastructure segment. See *Segment Results* below for additional information and discussion related to segment revenues.

*Cost of services.* Costs of services primarily includes wages, benefits, subcontractor costs, materials, equipment, and other direct and indirect costs, including related depreciation. The increase in cost of services generally correlates to the increase in revenues.

*Selling, general and administrative expenses.* The increase was primarily attributable to a $58.5 million increase related to recently acquired businesses and a $15.7 million increase in acquisition and integration costs.

*Amortization of intangible assets.* The increase was related to incremental amortization expense associated with recent acquisitions since June 2024, primarily the acquisition of CEI.

*Operating income.* Operating income was positively impacted by a $126.0 million increase in operating income for our Electric segment, partially offset by a $72.1 million increase in corporate and non-allocated costs, which includes amortization expense. Results for each of our business segments and our corporate and non-allocated costs are discussed in *Segment Results* below.

*Interest and other financing expenses.* The majority of the increase resulted from higher levels of principal on fixed rate debt balances as compared to the three months ended June 30, 2024. This increase resulted primarily from the issuance of $1.25 billion of aggregate principal amount of senior notes in August 2024, partially offset by the repayment of $500 million principal amount of senior notes in October 2024.

*Provision for income taxes*. The effective income tax rates for the three months ended June 30, 2025 and 2024 were 26.7% and 28.2%. The lower effective tax rate for the three months ended June 30, 2025 was primarily due to the recognition, as a component of our annual effective tax rate, of certain tax credits generated by one of our investments in a non-integral unconsolidated affiliate during the year ended December 31, 2025.

------

*Comprehensive income attributable to common stock.* See Statements of Comprehensive Income in Item 1. *Financial Statements* of Part I of this Quarterly Report. Comprehensive income attributable to common stock increased by $123.9 million in the three months ended June 30, 2025 as compared to the three months ended June 30, 2024, primarily due to an $83.0 million increase in foreign currency translation adjustments and a $41.6 million increase in net income. The predominant functional currencies for our operations outside the U.S. are Canadian and Australian dollars. Foreign currency translation adjustment gains for the three months ended June 30, 2025 primarily resulted from the weakening of the U.S. dollar against the Canadian and Australian dollars as of June 30, 2025 when compared to March 31, 2025.

*Revenues.* Revenues increased due to a $2.00 billion increase in revenues from our Electric segment and a $375.7 million increase in revenues from our Underground and Infrastructure segment. See *Segment Results* below for additional information and discussion related to segment revenues.

*Cost of services.* Costs of services primarily includes wages, benefits, subcontractor costs, materials, equipment, and other direct and indirect costs, including related depreciation. The increase in cost of services generally correlates to the increase in revenues.

*Selling, general and administrative expenses.* The increase was primarily attributable to a $112.4 million increase related to recently acquired businesses and a $34.4 million increase in compensation expense, largely associated with increased incentive compensation due also to increased levels of profitability. Also contributing to the increase was an $20.0 million increase in acquisition and integration costs.

*Amortization of intangible assets.* The increase was related to incremental amortization expense associated with acquisitions since June 2024, including CEI.

*Operating income.* Operating income was positively impacted by a $231.3 million increase in operating income for our Electric segment and a $39.1 million increase in operating income for our Underground and Infrastructure segment, partially offset by a $123.6 million increase in corporate and non-allocated costs, which includes amortization expense. Results for each of our business segments and corporate and non-allocated costs are discussed in *Segment Results* below.

*Interest and other financing expenses.* The majority of the increase resulted from higher levels of principal on fixed rate debt balances as compared to the six months ended June 30, 2024. This increase resulted primarily from the issuance of $1.25

------

billion of aggregate principal amount of senior notes in August 2024, partially offset by the repayment of $500 million principal amount of senior notes in October 2024.

*Other income (expense), net.* The decrease was primarily attributable to $16.4 million recognized in the six months ended June 30, 2024 resulting from the equity in earnings and the gain from the sale of an investment in a non-integral unconsolidated affiliate, $5.0 million of which was attributable to a non-controlling interest, as further described in Note 6 of the Notes to Condensed Consolidated Financial Statements in Item 1. *Financial Statements* of Part I of this Quarterly Report.

*Provision for income taxes.* The effective income tax rates for the six months ended June 30, 2025 and 2024 were 24.6% and 23.2%. The higher effective tax rate for the six months ended June 30, 2025 was primarily due to a lower tax benefit from equity incentive awards. This benefit impacted the effective tax rate for the six months ended June 30, 2025 by $14.7 million, compared to $22.4 million in the six months ended June 30, 2024.

*Comprehensive income attributable to common stock.* See Statements of Comprehensive Income in Item 1. *Financial Statements* of Part I of this Quarterly Report. Comprehensive income attributable to common stock increased by $180.8 million in the six months ended June 30, 2025 as compared to the six months ended June 30, 2024, primarily due to a $113.4 million increase in foreign currency translation adjustments and a $64.5 million increase in net income. The predominant functional currencies for our operations outside the U.S. are Canadian and Australian dollars. Foreign currency translation gains primarily resulted from the weakening of the U.S. dollar against the Canadian and Australian dollars as of June 30, 2025 when compared to December 31, 2024.

***Segment Results***

Reportable segment information, including revenues and operating income by type of work, is gathered from each of our operating companies. Classification of our operating company revenues by type of work for segment reporting purposes can at times require judgment on the part of management. Integrated operations and common administrative support for operating companies require that certain allocations be made to determine segment profitability, including allocations of corporate shared and indirect operating costs, as well as general and administrative costs. Certain corporate costs are not allocated, including corporate facility costs; non-allocated corporate salaries, benefits and incentive compensation; acquisition and integration costs; non-cash stock-based compensation; amortization related to intangible assets; asset impairments related to goodwill and intangible assets; and change in fair value of contingent consideration liabilities.

***Three months ended June 30, 2025 compared to the three months ended June 30, 2024***

***Electric Segment Results***

*Revenues*. The increase in revenues for the three months ended June 30, 2025 was primarily due to approximately $750 million in revenues attributable to acquired businesses as well as increased demand for our services.

*Operating Income*. The increase in operating income for the three months ended June 30, 2025 was primarily due to the increase in revenues. The increase in operating margin for the three months ended June 30, 2025 was primarily due to the increase in revenues and the overall mix of work performed in the period.

------

***Underground and Infrastructure Segment Results***

*Revenues*. The increase in revenues for the three months ended June 30, 2025 was primarily due to approximately $105 million in revenues attributable to acquired businesses as well as increased demand for our services.

*Operating Income*. The increase in operating income for the three months ended June 30, 2025 was primarily due to increased revenues. The decrease in operating margin for the three months ended June 30, 2025 was primarily due to an increase in estimates due to subcontractor management on an industrial project, partially offset by the overall mix of work performed in the period.

***Corporate and Non-Allocated Costs***

The increase in corporate and non-allocated costs during the three months ended June 30, 2025 was primarily due to a $34.0 million increase in intangible asset amortization expense associated with recent acquisitions, including CEI, and a $14.1 million increase in compensation expense, which was primarily attributable to increased incentive compensation expense due to increased levels of profitability and non-cash stock compensation expense in support of business growth. Also contributing to the increase was an $11.7 million increase in acquisition and integration costs.

***Six months ended June 30, 2025 compared to the six months ended June 30, 2024***

***Electric Segment Results***

*Revenues*. The increase in revenues for the six months ended June 30, 2025 was primarily due to approximately $1.54 billion in revenues attributable to acquired businesses as well as increased demand for our services.

*Operating Income*. The increase in operating income for the six months ended June 30, 2025 was primarily due to the increase in revenues. The increase in operating margin for the six months ended June 30, 2025 was primarily due to the increase in revenues and improved execution in power generation, partially offset by lower operating margins associated with telecommunication projects. Operating margin for the six months ended June 30, 2024 was negatively impacted by decreased operating income margins on various solar projects in the United States that were the result of decreased productivity.

***Underground and Infrastructure Segment Results***

*Revenues*. The increase in revenues for the six months ended June 30, 2025 was primarily due to approximately $200 million in revenues attributable to acquired businesses as well as increased demand for our services.

*Operating Income.* The increase in operating income and operating margin for the six months ended June 30, 2025 was primarily due to increased revenues, which contributed to higher levels of fixed cost absorption, as well as the overall mix of work performed during the period. Operating margin for the six months ended June 30, 2024 was negatively impacted by an $11.2 million loss related to the disposition of a non-core business.

------

***Corporate and Non-Allocated Costs***

The increase in corporate and non-allocated costs during the six months ended June 30, 2025 was primarily due to a $66.0 million increase in intangible asset amortization and a $23.4 million increase in compensation expense, which was attributable to increased salaries, incentive compensation and non-cash stock compensation expense in support of business growth and increased incentive compensation is also due to increased levels of profitability. Also contributing to the increase was an $11.6 million increase in acquisition and integration costs.

**Non-GAAP Financial Measures**

***EBITDA and Adjusted EBITDA***

EBITDA and adjusted EBITDA, financial measures not recognized under GAAP, when used in connection with net income attributable to common stock, are intended to provide useful information to investors and analysts as they evaluate our performance. EBITDA is defined as earnings before interest and other financing expenses, taxes, depreciation and amortization, and adjusted EBITDA is defined as EBITDA adjusted for certain other items as described below. These measures should not be considered as an alternative to net income attributable to common stock or other financial measures of performance that are derived in accordance with GAAP. Management believes that the exclusion of these items from net income attributable to common stock enables us and our investors to more effectively evaluate our operations period over period and to identify operating trends that might not be apparent due to, among other reasons, the variable nature of these items period over period. In addition, management believes these measures may be useful for investors in comparing our operating results with other companies that may be viewed as our peers.

As to certain of the items below, (i) non-cash stock-based compensation expense varies from period to period due to acquisition activity, changes in the estimated fair value of performance-based awards, forfeiture rates, accelerated vesting and amounts granted; (ii) acquisition and integration costs vary from period to period depending on the level and complexity of our acquisition activity; (iii) equity in (earnings) losses of non-integral unconsolidated affiliates varies from period to period depending on the activity and financial performance of such affiliates, the operations of which are not operationally integral to us; (iv) gains and losses on the sale of investments and businesses vary from period to period depending on activity; and (v) change in fair value of contingent consideration liabilities varies from period to period depending on the performance in post-acquisition periods of certain acquired businesses and the effect of present value accretion on fair value calculations. Because EBITDA and adjusted EBITDA, as defined, exclude some, but not all, items that affect net income attributable to common stock, such measures may not be comparable to similarly titled measures of other companies. The most comparable GAAP

<sup>(2)</sup> The amount for the six months ended June 30, 2024 is a loss of $11.2 million on the disposition of a non-core business, partially offset by a gain of $7.5 million as a result of the sale of a non-integral equity method investment.

***Remaining Performance Obligations and Backlog***

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

We have also historically disclosed our backlog, a measure commonly used in our industry but not recognized under GAAP. We believe this measure enables management to more effectively forecast our future capital needs and results and better identify future operating trends that may not otherwise be apparent. We believe this measure is also useful for investors in forecasting our future results and comparing us to our competitors. Our remaining performance obligations are a component of backlog, which also includes estimated orders under MSAs, including estimated renewals, and certain non-fixed price contracts. Our methodology for determining backlog may not be comparable to the methodologies used by other companies.

As of June 30, 2025 and December 31, 2024, MSAs accounted for 39% and 38% of our estimated 12-month backlog and 46% and 48% of our total backlog. Generally, our customers are not contractually committed to specific volumes of services under our MSAs, and most of our contracts can be terminated on short notice even if we are not in default. We determine the estimated backlog for these MSAs using recurring historical trends, factoring in seasonal demand and projected customer needs based upon ongoing communications. In addition, many of our MSAs are subject to renewal, and these potential renewals are considered in determining estimated backlog. As a result, estimates for remaining performance obligations and backlog are subject to change based on, among other things, project accelerations; project cancellations or delays, including but not limited 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.

<sup>(1)</sup> Excludes backlog from contracts that are still subject to certain regulatory approvals.

The increases in both remaining performance obligations and backlog from December 31, 2024 to June 30, 2025 were partially due to the impact of acquisitions that occurred in the six months ended June 30, 2025 as well as new project awards with existing customers.

**Liquidity and Capital Resources**

***Overview***

We plan to fund our working capital, capital expenditures, debt service, dividends and other cash requirements with our current available liquidity and cash from operations, which could be affected by general economic, financial, competitive, legislative, regulatory, business and other factors, many of which are beyond our control. Management monitors financial markets and national and global economic conditions for factors that may affect our liquidity and capital resources.

Our capital deployment priorities that require the use of cash include: (i) working capital to fund ongoing operating needs, (ii) capital expenditures to meet anticipated demand for our services, (iii) acquisitions and investments to facilitate the long-term growth and sustainability of our business, and (iv) return of capital to stockholders, including through the payment of dividends and repurchases of our outstanding common stock.

***Cash Requirements and Capital Allocation***

During the six months ended June 30, 2025, there were no material changes outside the ordinary course of business in the specified contractual obligations or changes to our capital allocation priorities as set forth in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations in Part II of the 2024 Annual Report. We anticipate that our future cash flows from operating activities, cash and cash equivalents on hand, existing borrowing capacity under our senior credit facility and commercial paper program and ability to access capital markets for additional capital will provide sufficient funds to enable us to meet our cash requirements for the next twelve months and over the longer term.

On July 25, 2025, we utilized $700.0 million of borrowings under our commercial paper program and availability under our revolving credit facility to finance the cash portion of the acquisition of Dynamic Systems.

During the six months ended June 30, 2025, we completed the acquisition of four businesses in which a portion of the consideration, net of cash acquired, consisted of $586.1 million in cash paid on the respective acquisition dates, funded with a combination of cash and cash equivalents and borrowings from our commercial paper program. For additional information regarding our recent acquisitions, refer to Note 5 of the Notes to Condensed Consolidated Financial Statements in Item 1.

------

*Financial Statements* of Part I of this Quarterly Report.

We anticipate that our future cash flows from operating activities, cash and cash equivalents on hand, existing borrowing capacity under our senior credit facility and commercial paper program and ability to access capital markets for additional capital will provide sufficient funds to enable us to meet our cash requirements for the next twelve months and over the longer term.

***Significant Sources of Cash***

Cash flow from operating activities is primarily influenced by demand for our services and operating margins but is also influenced by the timing of working capital needs associated with the various types of services that we provide. Our working capital needs may increase when we commence large volumes of work under circumstances where project costs are required to be paid before the associated receivables are billed and collected. Working capital needs are generally higher during the summer and fall due to increased demand for our services when favorable weather conditions exist in many of our operating regions. Conversely, working capital assets are typically converted to cash during the winter. These seasonal trends can be offset by changes in project timing due to delays or accelerations and other economic factors that may affect customer spending, including market conditions or the impact of certain unforeseen events (e.g., regulatory and other actions that impact the supply chain for certain materials). Additionally, operating cash flows may be negatively impacted as a result of unpaid and delayed change orders and claims. Changes in project timing due to delays or accelerations and other economic, regulatory, market and political factors that may affect customer spending could also impact cash flow from operating activities. Further information with respect to our cash flow from operating activities is set forth below and in Note 15 of the Notes to Condensed Consolidated Financial Statements in Item 1. *Financial Statements* of Part I of this Quarterly Report*.*

Our available commitments under our senior credit facility and cash and cash equivalents as of June 30, 2025 were as follows (in thousands):

---

| | |
|:---|:---|
| | **June 30, 2025** |
| Total capacity available for revolving loans, credit support for commercial paper program and letters of credit | $2800000 |
| Less: |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Commercial paper program notes outstanding <sup>(1)</sup> | 600000 |
| &nbsp;&nbsp;&nbsp;&nbsp;Letters of credit outstanding | 69074 |
| Available commitments for revolving loans, credit support for commercial paper notes and letters of credit | 2130926 |
| Plus: |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Cash and cash equivalents <sup>(2)</sup> | 509460 |
| Total  | $2640386 |

---

<sup>(1)</sup> &nbsp;&nbsp;&nbsp;&nbsp;Amount represents unsecured notes issued under our commercial paper program, which has a maximum aggregate amount of $1.50 billion of notes outstanding at any time. Available commitments for revolving loans under our senior credit facility must be maintained to provide credit support for notes issued under our commercial paper program, and therefore such notes effectively reduce the available borrowing capacity under our senior credit facility.

<sup>(2)</sup> &nbsp;&nbsp;&nbsp;&nbsp;Further information with respect to our cash and cash equivalents is set forth below and in Note 14 of the Notes to Condensed Consolidated Financial Statements in Item 1. *Financial Statements* of Part I of this Quarterly Report. This amount includes $305.4 million in jurisdictions outside of the U.S., principally in Australia. There are currently no legal or economic restrictions that would materially impede our ability to repatriate such cash.

Subsequent to June 30, 2025, we extended the maturity date for revolving loans under the credit agreement for our senior credit facility from July 31, 2029 to July 31, 2030.

We consider our investment policies related to cash and cash equivalents to be conservative, as we maintain a diverse portfolio of what we believe to be high-quality cash and cash equivalent investments with short-term maturities. Additionally, subject to the conditions specified in the credit agreement for our senior credit facility, we have the option to increase the capacity of our senior credit facility, in the form of an increase in the revolving commitments, term loans or a combination thereof, from time to time, upon receipt of additional commitments from new or existing lenders by up to an additional (i) $400.0 million plus (ii) additional amounts so long as the Incremental Leverage Ratio Requirement (as defined in the credit agreement) is satisfied at the time of such increase. The Incremental Leverage Ratio Requirement requires, among other things, after giving pro forma effect to such increase and the use of proceeds therefrom, compliance with the credit agreement's financial covenants as of the most recent fiscal quarter end for which financial statements were required to be delivered. Further

------

information with respect to our debt obligations is set forth in Note 8 of the Notes to Condensed Consolidated Financial Statements in Item 1. *Financial Statements* of Part I of this Quarterly Report*.* 

We are evaluating our longer-term debt financing options, and we may seek to access the capital markets from time to time to raise additional capital, increase liquidity as we deem necessary, refinance or extend the term of our existing indebtedness, fund acquisitions or otherwise fund our capital needs. While our financial strategy and consistent performance have allowed us to maintain investment grade ratings, our ability to access capital markets in the future depends on a number of factors, including our financial performance and financial position, our credit ratings, industry conditions, general economic conditions, our backlog, capital expenditure commitments, market conditions and market perceptions of us and our industry. In July 2025, Moody's revised its outlook on our Baa3 investment grade ratings from stable to positive.

***Sources and Uses of Cash, Cash Equivalents and Restricted Cash During the Six Months Ended June 30, 2025 and 2024***

In summary, our cash flows for each period were as follows (in thousands):

---

| | | |
|:---|:---|:---|
| | **Six Months Ended** | **Six Months Ended** |
| | **June 30,** | **June 30,** |
| | **2025** | **2024** |
| Net cash provided by operating activities | $538909 | $629267 |
| Net cash used in investing activities | $(980546) | $(589260) |
| Net cash provided by (used in) financing activities  | $186747 | $(806298) |

---

*Operating Activities*

Net cash provided by operating activities of $538.9 million and $629.3 million in the six months ended June 30, 2025 and 2024 primarily reflected earnings adjusted for non-cash items and cash provided and used by the main components of working capital: "Accounts and notes receivable," "Contract assets," "Prepaid expenses and other current assets," "Accounts payable and accrued expenses," and "Contract liabilities."

Days sales outstanding (DSO) represents the average number of days it takes revenues to be converted into cash, which management believes is an important metric for assessing liquidity. A decrease in DSO has a favorable impact on cash flow from operating activities, while an increase in DSO has a negative impact on cash flow from operating activities. DSO is calculated by using the sum of current accounts receivable, net of allowance (which includes retainage and unbilled balances), plus contract assets, less contract liabilities, and divided by average revenues per day during the quarter. DSO as of June 30, 2025 was 62 days, which was lower than DSO of 68 days as of June 30, 2024 and lower than our five-year historical average DSO of 76 days. This decrease in DSO as compared to June 30, 2024 was partially due to favorable billing terms on certain large projects. Negatively impacting DSO and cash flow from operating activities for both the six months ended June 30, 2025 and 2024 were unapproved change orders and claims included in contract assets from the large renewable transmission project in Canada further described in Note 3 of the Notes to Condensed Consolidated Financial Statements in Item 1. *Financial Statements* of Part I of this Quarterly Report. Net cash provided by operating activities for the six months ended June 30, 2025 was negatively impacted by payment of approximately $109.1 million related to the deferral of 2024 quarterly federal income tax pursuant to federal disaster relief.

*Investing Activities*

Net cash used in investing activities in the six months ended June 30, 2025 included $586.1 million related to acquisitions, $273.1 million of capital expenditures and $148.3 million of cash paid primarily for an integral equity method investment.

Net cash used in investing activities in the six months ended June 30, 2024 included $450.8 million related to acquisitions and $244.6 million of capital expenditures. Partially offsetting these items were $55.2 million of proceeds from the sale of, and insurance settlements related to, property and equipment; $29.2 million of proceeds from the sale of a non-integral equity investment and $28.7 million of proceeds from the disposition of a non-core business.

Our industry is capital intensive, and we expect substantial capital expenditures and commitments for equipment purchases and equipment lease and rental arrangements to be needed for the foreseeable future in order to meet anticipated demand for our services. In addition, we expect to continue to pursue strategic acquisitions and investments, although we cannot predict the timing or amount of the cash needed for these initiatives. We also have various other capital commitments that are detailed in *Cash Requirements and Capital Allocation* above and in Item 7. *Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources* of Part I of our 2024 Annual Report.

------

*Financing Activities*

Net cash provided by financing activities in the six months ended June 30, 2025 was primarily due to $557.8 million net borrowings under our commercial paper program, partially offset by $134.6 million of repurchases of common stock, $102.6 million of payments for contingent consideration liabilities, $72.6 million of payments to satisfy tax withholding obligations associated with stock-based compensation and $30.3 million for the payment of dividends.

Net cash used in financing activities in the six months ended June 30, 2024 included $707.0 million of net repayments under our senior credit facility and commercial paper program, $77.8 million of payments to satisfy tax withholding obligations associated with stock-based compensation and the payment of $27.0 million of dividends.

We expect to continue to utilize cash for similar financing activities in the future, including repayments of our outstanding debt, payment of cash dividends and repurchases of our common stock and/or debt securities.

**Critical Accounting Estimates** 

The discussion and analysis of our financial condition and results of operations are based on our condensed consolidated financial statements, which have been prepared in accordance with GAAP. Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with GAAP, have been condensed or omitted pursuant to those rules and regulations. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities known to exist as of the date the condensed consolidated financial statements are published and the reported amounts of revenues and expenses recognized during the periods presented. We review all significant estimates affecting our condensed consolidated financial statements on a recurring basis and record the effect of any necessary adjustments prior to their publication. Judgments and estimates are based on our beliefs and assumptions derived from information available at the time such judgments and estimates are made. Uncertainties with respect to such estimates and assumptions are inherent in the preparation of financial statements. There can be no assurance that actual results will not differ from those estimates. Management has reviewed its development and selection of critical accounting estimates with the audit committee of our Board of Directors. Our accounting policies are primarily described in Notes 2 and 4 of the Notes to Consolidated Financial Statements in Item 8. *Financial Statements and Supplementary Data* in Part II of the 2024 Annual Report and should be read in conjunction with the accounting policies identified in Item 7. *Management's Discussion and Analysis of Financial Condition and Results of Operations* of Part II of our 2024 Annual Report, which we believe affect our more significant estimates.

**Item 3.*Quantitative and Qualitative Disclosures about Market Risk.***

There were no material changes to our quantitative and qualitative disclosures about market risk during the six months ended June 30, 2025. Our primary exposure to market risk relates to unfavorable changes in interest rates and currency exchange rates. Refer to the information on financial market risk related to changes in interest rates and foreign currency exchange rates in Item 7A. *Quantitative and Qualitative Disclosures About Market Risk* of Part II of our 2024 Annual Report.

**Item 4.*Controls and Procedures.***

Attached as exhibits to this Quarterly Report on Form 10-Q are certifications of Quanta's Chief Executive Officer and Chief Financial Officer that are required in accordance with Rule 13a-14 of the Securities Exchange Act of 1934, as amended (the Exchange Act). This Item 4. section includes information concerning the controls and controls evaluation referred to in the certifications, and it should be read in conjunction with the certifications for a more complete understanding of the topics presented.

**Evaluation of Disclosure Controls and Procedures**

Our management has established and maintains a system of disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act, such as this Quarterly Report on Form 10-Q, is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms. The disclosure controls and procedures are also designed to provide reasonable assurance that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

As of the end of the period covered by this Quarterly Report, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b), as such disclosure controls and procedures are defined in

------

Rule 13a-15(e) and 15d-15(e) of the Exchange Act. This evaluation was carried out under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer. Based on this evaluation, these officers have concluded that, as of June 30, 2025, our disclosure controls and procedures were effective to provide reasonable assurance of achieving their objectives.

**Evaluation of Internal Control over Financial Reporting**

We acquired four businesses during the six months ended June 30, 2025. We are in the process of integrating these acquired businesses into our overall internal control over financial reporting process.

Except as noted above, there has been no change in our internal control over financial reporting that occurred during the quarter ended June 30, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

**Design and Operation of Control Systems**

Our management, including the Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and breakdowns can occur because of simple errors or mistakes. Controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

**PART II — OTHER INFORMATION**

**Item 1. *Legal Proceedings.***

We are from time to time party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, property damage, breach of contract, negligence or gross negligence, environmental liabilities, wage and hour claims and other employment-related damages, punitive damages, consequential damages, civil penalties or other losses, or injunctive or declaratory relief, as well as interest and attorneys' fees associated with such claims. With respect to all such lawsuits, claims and proceedings, we record a reserve when we believe it is probable that a loss has been incurred and the amount of loss can be reasonably estimated. In addition, we disclose matters for which management believes a material loss is at least reasonably possible. See Note 13 of the Notes to Condensed Consolidated Financial Statements in Item 1. *Financial Statements* of Part I of this Quarterly Report, which is incorporated by reference in this Item 1, for additional information regarding litigation, claims and other legal proceedings.

**Environmental Matters**

Item 103 of Regulation S-K requires disclosure of certain environmental matters in which a governmental authority is a party to the proceedings and when such proceedings involve the potential for monetary sanctions that management reasonably believes will exceed a specified threshold. Pursuant to SEC regulations, we use a threshold of $1.0 million for such proceedings.

**Item 1A. *Risk Factors.***

Our business is subject to a variety of risks and uncertainties that are difficult to predict and many of which are outside of our control. For a detailed discussion of the risks that affect our business, refer to Item 1A. *Risk Factors* of Part I of our 2024 Annual Report. As of the date of this filing, there have been no material changes to the risk factors previously described in our 2024 Annual Report. The matters specifically identified are not the only risks and uncertainties facing our company, and risks and uncertainties not known to us or not specifically identified also may impair our business operations. If any of these risks and uncertainties occur, our business, financial condition, results of operations and cash flows could be negatively affected, which could negatively impact the value of an investment in our company.

**Item 2.*Unregistered Sales of Equity Securities and Use of Proceeds.***

**Unregistered Sales of Equity Securities**

On May 19, 2025, we completed the acquisition of a minority interest in which a portion of the consideration for the interest consisted of the unregistered issuance of shares of our common stock. On May 22, 2025 and June 20, 2025, we settled contingent consideration liabilities related to certain acquisitions, and a portion of the settlement consisted of the unregistered issuance of shares of our common stock. The aggregate settlement for these acquisitions included 257,357 shares of our common stock, valued at $86.0 million based on each respective measurement date. Additionally, subsequent to June 30, 2025, we completed an acquisition on July 25, 2025, in which a portion of the consideration for the acquisition consisted of the unregistered issuance of shares of our common stock. The aggregate consideration paid at closing in this acquisition included 518,772 shares of our common stock, valued at $218.8 million as of the acquisition date.

The shares of common stock issued in these transactions were issued in reliance upon the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended, as the shares were issued to the owners of the businesses acquired in privately negotiated transactions not involving any public offering or solicitation.

For additional information about these acquisitions, see Note 5 of the Notes to Condensed Consolidated Financial Statements in Item 1. *Financial Statements* of Part I of this Quarterly Report*.*

RE: Transfer to Transition Employment Status

Dear Derrick,

On behalf of Quanta Services Management Partnership, L.P. ("QSMP"), we are pleased to offer you employment in Quanta Services, Inc.'s ("Quanta") Key Employee Transition Program (the "Transition Program") on the terms and conditions set forth in this letter, effective June 1, 2025. This change in employment status will have an impact on your work hours, compensation, benefits, and other related aspects.

The following outlines the material terms of your offer of employment in the Transition Program.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Salary:** Semi-Monthly Amount of $8,333.33 (Annualized at $200,000), payable in accordance with QSMP's payroll practices.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Cash Bonus and Equity Grants:** Unless otherwise provided in a subsequent written agreement between you and Quanta or QSMP, you will not be eligible to participate in future bonus plans, nor be eligible for future grants under the Quanta Services, Inc. 2019 Omnibus Equity Incentive Plan (the "Plan").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Benefits:** You are eligible to participate as outlined in the Quanta Key Employee Transition Program Summary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Employment Effective Dates**: Your employment in the Transition Program will begin on June 1, 2025, and end on March 31, 2028.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Job Title**: Business Administration Advisor

You agree that, during your employment in the Transition Program, you will not engage in any other employment, consulting, or other business activity related to the business in which Quanta and its operating companies are now involved or may become involved during your employment. You also agree you will not engage in any activities that conflict with your obligations to Quanta. Further, you verify you will not bring or disclose any third-party confidential information or trade secrets to Quanta, including, but not limited to that of any former employer, and that in performing your duties for Quanta you will not in any way utilize such information.

This letter represents an offer of employment and is not an employment contract or guarantee of employment for any period of time. Your employment relationship with QSMP will be on an "at will" basis, meaning that either you or QSMP may terminate your employment at any time for any reason or no reason. Quanta and QSMP also reserve the right to modify or amend the terms of your employment at any time, for any reason.

------

**Exhibit 10.2**

Although your job duties, title, compensation, and benefits, as well as Quanta's personnel policies and procedures may change from time to time, the "at will" nature of your employment may only be changed in an express written agreement signed by you and Quanta's Chief Executive Officer.

This letter supersedes and replaces any previous discussions, representations, or agreements you may have had about the terms of your employment with Quanta, with the exception of any terms related to confidentiality, fiduciary duties, and/or obligations created under the Plan and any Award (as defined in the Plan) agreement.

Please sign this letter to acknowledge your acceptance of the terms of this offer letter, no later than 3 days from the date it is received. Once we have received your signed offer letter, Human Resources will contact you to go over remaining paperwork and next steps.

I agree to the terms of the offer letter set forth above.
