Accounting Standards [Abstract]
Accounting Standards	Accounting Standards Recently issued accounting pronouncements are disclosed in the Company’s Annual Report on Form 10-K for fiscal 2026. As of the date of this Quarterly Report on Form 10-Q, there have been no changes in the expected dates of adoption or estimated effects on the Company’s condensed consolidated financial statements of recently issued accounting pronouncements from those disclosed in the Company’s Annual Report on Form 10-K for fiscal 2026. Further, there have been no additional accounting standards issued as of the date of this Quarterly Report on Form 10-Q that are applicable to the condensed consolidated financial statements of the Company. Recently Adopted Accounting Standards None. Accounting Standards Not Yet Adopted Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. In November 2024, the FASB issued ASU 2024-03, Income Statement (Subtopic 220-40): Disaggregation of Income Statement Expenses. This ASU requires public entities to disclose, in the notes to the financial statements, specified information about certain costs and expenses at each interim and annual reporting period. In January 2025, the FASB issued ASU 2025-01, Income Statements (Subtopic 220-40): Clarifying the Effective Date. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the impact of the standard on our condensed consolidated financial statements. Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The ASU modernizes the approach for internal-use software by eliminating the previous stage-based capitalization model so that the guidance is neutral to different software development projects. Entities may apply the guidance using a prospective, retrospective or modified transition approach. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027. We are currently evaluating the impact of the standard on our condensed consolidated financial statements. All other new accounting pronouncements that have been issued but not yet effective are currently being evaluated and at this time are not expected to have a material impact on our financial position or results of operations.

The entire disclosure for change in accounting principle. Includes, but is not limited to, nature, reason, and method of adopting amendment to accounting standards or other change in accounting principle.

Accounting Policies [Abstract]
Significant Accounting Policies and Estimates	Significant Accounting Policies and Estimates There have been no material changes to the Company’s significant accounting policies and critical accounting estimates described in the Company’s Annual Report on Form 10-K for fiscal 2026. Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the amounts reported in these condensed consolidated financial statements and accompanying notes. These estimates are based on our historical experience and management’s understanding of current facts and circumstances. At the time they are made, we believe that such estimates are fair when considered in conjunction with the Company’s consolidated financial position and results of operations taken as a whole. However, actual results could differ materially from those estimates. Per Share Data. Basic earnings per common share is computed based on the weighted average number of common shares outstanding during the period, excluding unvested restricted share units. Diluted earnings per common share includes the weighted average number of common shares outstanding during the period and dilutive potential common shares arising from our stock-based awards (including unvested restricted share units) if their inclusion is dilutive under the treasury stock method. Common stock equivalents related to stock-based awards are excluded from diluted earnings per common share calculations if their effect would be anti-dilutive. Leases. Prior to the acquisition of National Technology Integrators during the three months ended August 1, 2026, our lease population consisted solely of operating leases. See Note 5, Acquisitions, for information on our recent acquisition. We account for our leases as either finance or operating leases when the initial lease term is greater than 12 months. The lease term may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Leases with an initial term of 12 months or less are not recorded on our consolidated balance sheet. The right-of-use assets for finance leases are included on our consolidated balance sheet in property and equipment, net of accumulated depreciation, with a corresponding amount recorded in current portion of debt or long-term debt, as appropriate. The finance lease assets are amortized on a straight-line basis over the lease term and included in depreciation expense. The financing component associated with finance lease obligations is included in interest expense. As our finance leases were part of the National Technology Integrators acquisition, we used our incremental borrowing rate based on the information available at the acquisition date in determining the present value of the remaining lease payments. Operating leases are included in operating lease right-of-use assets and corresponding operating lease liabilities. Operating lease right-of-use assets represent our right to use the underlying asset for the lease term and operating lease liabilities represent our obligation to make the related lease payments. These assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As our operating leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments.

Remaining Performance Obligations

Master service agreements and other contractual agreements with customers contain customer-specified service requirements, such as discrete pricing for individual tasks and firm orders under fixed price contracts which have not yet started or been fully completed. In most cases, our customers are not contractually committed to procure specific volumes of services under these agreements.

Services are generally performed pursuant to these agreements in accordance with individual work orders. An individual work order generally is completed within one year. As a result, our remaining performance obligations under the work orders not yet completed is not meaningful in relation to our overall revenue at any given point in time. We apply the practical expedient in Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, and do not disclose information about remaining performance obligations that have original expected durations of one year or less.

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.

Share-Based Payment Arrangement [Abstract]

Stock-Based Awards

6 Months Ended

Aug. 01, 2026

Stock-Based Awards

We have certain stock-based compensation plans under which we grant stock-based awards, including common stock, stock options, time-based restricted share units (“RSUs”), and performance-based restricted share units (“Performance RSUs”) to attract, retain, and reward talented employees, officers, and directors, and to align stockholder and employee interests.

Compensation expense for stock-based awards is based on fair value at the measurement date. This expense fluctuates over time as a function of the duration of vesting periods of the stock-based awards and the Company’s performance, as measured by criteria set forth in performance-based awards. Stock-based compensation expense is included in general and administrative expenses in the condensed consolidated statements of operations and the amount of expense ultimately recognized depends on the quantity of awards that actually vest. Accordingly, stock-based compensation expense may vary from period to period.

The performance criteria for the Company’s performance-based equity awards utilize the Company’s operating earnings (adjusted for certain amounts) as a percentage of contract revenues for the applicable annual period (a “Performance Year”) and its Performance Year operating cash flow level (adjusted for certain amounts). Additionally, certain awards include three-year performance measures that, if met, result in supplemental shares awarded. For Performance RSUs, the Company evaluates compensation expense quarterly and recognizes expense for performance-based awards only if it determines it is probable that performance criteria for the awards will be met.

Stock-based compensation expense and the related tax benefit recognized during the three and six months ended August 1, 2026 and July 26, 2025 were as follows (dollars in thousands):


	For the Three Months Ended				For the Six Months Ended
	August 1, 2026		July 26, 2025		August 1, 2026		July 26, 2025
Stock-based compensation	$	10,288	$	8,100	$	20,862	$	17,199
Income tax effect of stock-based compensation	$	2,504	$	1,998	$	5,084	$	4,237

During the three months ended August 1, 2026 and July 26, 2025, the Company realized $3.6 million and $0.6 million of net excess tax benefits, respectively, related to the vesting and exercise of share-based awards. During the six months ended August 1, 2026 and July 26, 2025, the Company realized approximately $16.1 million and $2.8 million of net excess tax benefits, respectively, related to the vesting and exercise of share-based awards.

As of August 1, 2026, we had unrecognized compensation expense related to stock options, RSUs, and target Performance RSUs (based on the Company’s expected achievement of performance measures) of $0.5 million, $50.4 million, and $17.2 million, respectively. This expense will be recognized over a weighted-average number of years of 1.4, 2.2, and 1.3, respectively, based on the average remaining service periods for the awards. We may recognize an additional $13.1 million in compensation expense in future periods after August 1, 2026 if the maximum number of Performance RSUs is earned based on certain performance measures being met.

For claims within our insurance program, we retain the risk of loss, up to certain annual stop-loss limits, for matters related to automobile liability, general liability (including damages associated with underground facility locating services), workers’ compensation, and employee group health. Losses for claims beyond our retained risk of loss are covered by insurance up to our coverage limits. As of June 2026, losses for Power Solutions, in our Building Systems segment, are included in our insurance program. National Technology Integrators, in our Building Systems segment, is fully insured for these risks through third-party insurance policies, and we do not retain the risk of loss for claims related to those operations.

For workers’ compensation losses during fiscal 2027 and 2026, we retained the risk of loss up to $1.0 million on a per occurrence basis. This retention amount is applicable to all of the states in which we operate, except with respect to workers’ compensation insurance in two states in which we participate in state-sponsored insurance funds.

For automobile liability and general liability losses during fiscal 2027 and 2026, we retained the risk of loss up to $2.0 million on a per-occurrence basis for the first $5.0 million of insurance coverage. We also retained the risk of loss for the next $5.0 million on a per-occurrence basis for losses between $5.0 million and $10.0 million, if any.

We are party to a stop-loss agreement for losses under our employee group health plan. For calendar year 2026, we retain the risk of loss on an annual basis, up to the first $750,000 of claims per participant.

Amounts for total accrued insurance claims and insurance recoveries/receivables are as follows (dollars in thousands):


	August 1, 2026		January 31, 2026
Accrued insurance claims - current	$	51,127	$	47,594
Accrued insurance claims - non-current	69,767		57,977
Accrued insurance claims	$	120,894	$	105,571

Insurance recoveries/receivables:

Non-current (included in Other assets)	10,076		8,570
Insurance recoveries/receivables	$	10,076	$	8,570

Insurance recoveries/receivables represent the amount of accrued insurance claims that are covered by insurance as the amounts exceed the Company’s loss retention. During the six months ended August 1, 2026, total insurance recoveries/receivables increased as a result of additional claims that exceeded our loss retention. Accrued insurance claims increased by a corresponding amount.

Goodwill and Intangible Assets

Goodwill

The Company’s goodwill balance was $1,598.9 million and $1,443.4 million as of August 1, 2026 and January 31, 2026, respectively. Changes in the carrying amount of goodwill consisted of the following (dollars in thousands):


	Communications		Building Systems		Total
Balance as of January 31, 2026	$	332,645	$	1,110,790	$	1,443,435

Goodwill adjustment from fiscal 2026 acquisition	—		13,642		13,642
Goodwill from fiscal 2027 acquisition	—		141,869		141,869
Balance as of August 1, 2026	$	332,645	$	1,266,301	$	1,598,946

The aggregate goodwill balance as of August 1, 2026 and January 31, 2026 includes $249.0 million of accumulated impairment charges all of which relate to the Communications segment.

The Company’s goodwill resides in multiple reporting units and primarily consists of expected synergies, together with the expansion of our geographic presence and service offerings, and the strengthening and expansion of our customer base from acquisitions. The profitability of individual reporting units may suffer periodically due to downturns in customer demand, increased costs of providing services, and the level of overall economic activity. Our customers may reduce capital expenditures and defer or cancel pending projects due to changes in technology, a slowing or uncertain economy, merger or acquisition activity, a decision to allocate resources to other areas of their business, or other reasons. The profitability of reporting units may also suffer if actual costs of providing services exceed the costs anticipated when the Company enters into contracts. Additionally, adverse conditions in the economy and future volatility in the equity and credit markets could impact the valuation of our reporting units. The cyclical nature of our business, the high level of competition existing within our industry, and the concentration of our revenues from a limited number of customers may also cause results to vary. These factors may affect individual reporting units disproportionately, relative to the Company as a whole. As a result, the performance of one or more of the reporting units could decline, resulting in an impairment of goodwill or intangible assets.

The Company performs its annual goodwill assessment as of the first day of the fourth fiscal quarter of each fiscal year. As a result of the Company’s fiscal 2026 period assessment, the Company determined that the fair values of each of the reporting units and the indefinite-lived intangible asset were in excess of their carrying values and no impairment had occurred. As of August 1, 2026, we believe the carrying amounts of goodwill and the indefinite-lived intangible asset are recoverable for all of our reporting units.

Intangible Assets

Our intangible assets consisted of the following (dollars in thousands):


	August 1, 2026							January 31, 2026
	Weighted Average Remaining Useful Lives (Years)	Gross Carrying Amount		Accumulated Amortization		Intangible Assets, Net		Gross Carrying Amount		Accumulated Amortization		Intangible Assets, Net
Customer relationships	13.4	$	1,121,217	$	356,215	$	765,002	$	1,032,417	$	306,094	$	726,323
Trade names, finite	13.7	54,080		11,801		42,279		54,080		10,178		43,902
Trade name, indefinite	Indefinite	4,700		—		4,700		4,700		—		4,700
Contract backlog	1.1	232,300		108,911		123,389		192,900		41,903		150,997
Non-compete agreements	1.3	75		56		19		75		49		26
		$	1,412,372	$	476,983	$	935,389	$	1,284,172	$	358,224	$	925,948

Amortization of our customer relationship intangibles and our backlog intangibles are recognized on an accelerated basis as a function of the expected economic benefit. Amortization of our other finite-lived intangibles is recognized on a straight-line basis over the estimated useful life. Amortization expense for finite-lived intangible assets was $60.5 million and $11.9 million for the three months ended August 1, 2026 and July 26, 2025, respectively, and $118.8 million and $23.9 million for the six months ended August 1, 2026 and July 26, 2025, respectively.

As of August 1, 2026, total amortization expense for existing finite-lived intangible assets for the next five fiscal years and thereafter is as follows (dollars in thousands):


	Amount
Remainder of 2027	$	119,742
2028	168,297
2029	102,325
2030	101,852
2031	71,109
2032	68,514
Thereafter	298,850
Total	$	930,689

As of August 1, 2026, we believe that the carrying amounts of our intangible assets are recoverable. However, if adverse events were to occur or circumstances were to change indicating that the carrying amount of such assets may not be fully recoverable, the assets would be reviewed for impairment and the assets could be impaired.

Stockholders' Equity Note [Abstract]
Capital Stock	Capital Stock Repurchases of Common Stock. On February 26, 2025, the Company announced that its Board of Directors authorized a new $150 million program to repurchase shares of the Company’s outstanding common stock through August 25, 2026 in open market or private transactions. During the three months ended May 2, 2026, the Company repurchased 100,000 shares of common stock, at an average price of $359.63, for $36.0 million. There were no share repurchases during the three months ended August 1, 2026. As of August 1, 2026, $83.9 million of the authorization was available for repurchases. Restricted Stock Tax Withholdings. During the six months ended August 1, 2026 and July 26, 2025, we withheld 85,783 shares totaling $29.4 million and 84,296 shares totaling $13.0 million, respectively, to meet payroll tax withholding obligations arising from the vesting of restricted share units. All shares withheld have been cancelled. Shares of common stock withheld for tax withholdings do not reduce our total share repurchase authority. Upon cancellation of shares repurchased or withheld for tax withholdings, the excess over par value is recorded as a reduction of additional paid-in capital until the balance is reduced to zero, with any additional excess recorded as a reduction of retained earnings. Issuance of Common Stock for Acquisition. In connection with the acquisition of National Technology Integrators on July 2, 2026, the Company issued 95,550 shares of Dycom common stock to the sellers valued at $45.0 million, as partial consideration for the purchase. These shares were issued in a private placement exempt from registration under the Securities Act of 1933.

The consolidated senior secured net leverage ratio is the ratio (a)(i) of our consolidated senior secured indebtedness reduced by (ii) unrestricted cash and equivalents in excess of $25.0 million to (b) to our trailing four-quarter consolidated earnings before interest, taxes, depreciation, and amortization, as defined by the Credit Agreement (“EBITDA”). Borrowings under the Credit Agreement are guaranteed by substantially all of our domestic subsidiaries and secured by substantially all of the assets of the Borrowers and the Guarantors (subject to customary exceptions).

Under our Credit Agreement, borrowings bear interest at the rates described below based upon our consolidated net leverage ratio, which is the ratio of (a) our consolidated total funded debt reduced by unrestricted cash and equivalents in excess of $25.0 million to (b) our trailing four-quarter consolidated EBITDA. In addition, we incur certain fees for unused balances and letters of credit at the rates described below, also based upon our consolidated net leverage ratio. The weighted average interest rates and fees for balances under our Credit Agreement as of August 1, 2026 and January 31, 2026 were as follows:


		Weighted Average Rate End of Period
		August 1, 2026	January 31, 2026
Borrowings - Term A SOFR Loans	1.375% - 2.00% plus Term SOFR	5.40%	5.43%
Borrowings - Base Rate Loans	0.375% - 1.00% plus Base rate(1)	—%	—%
Borrowings - Term B SOFR Loans	1.75% plus Term SOFR	5.40%	5.43%
Unused Revolver Commitment	0.20% - 0.40%	0.35%	0.35%
Standby Letters of Credit	1.375% - 2.00%	1.75%	1.75%
Commercial Letters of Credit	0.6875% -1.00%	—%	—%

Standby letters of credit of approximately $53.6 million issued as part of our insurance program, were outstanding under our Credit Agreement as of August 1, 2026 and January 31, 2026.

Our Credit Agreement contains a financial covenant that requires us to maintain a maximum consolidated net leverage ratio of not greater than (A) until the last day of the first fiscal quarter ending after the second anniversary of December 23, 2025, 4.50 to 1.00, and (B) thereafter, 4.00:1.00, as measured at the end of each fiscal quarter, and provides for certain increases to this ratio in connection with permitted acquisitions. The agreement also contains a financial covenant that requires us to maintain a minimum consolidated interest coverage ratio, which is the ratio of our trailing four-quarter consolidated EBITDA to our consolidated interest expense, as defined by our Credit Agreement, of not less than 2.50 to 1.00, as measured at the end of each fiscal quarter. At August 1, 2026 and January 31, 2026, we were in compliance with the financial covenants of our Credit Agreement and had borrowing availability under our revolving facility of $746.4 million.

4.50% Senior Notes Due 2029

On April 1, 2021, we issued $500.0 million aggregate principal amount of 4.50% senior notes due 2029 (the “2029 Notes”). The 2029 Notes are guaranteed on a senior unsecured basis, jointly and severally, by all of our domestic subsidiaries that guarantee the Credit Agreement.

The indenture governing the 2029 Notes contains certain covenants that limit, among other things, our ability and the ability of certain of our subsidiaries to (i) incur additional debt and issue certain preferred stock, (ii) pay certain dividends on, repurchase, or make distributions in respect of, our and our subsidiaries’ capital stock or make other payments restricted by the indenture, (iii) enter into agreements that place limitations on distributions made from certain of our subsidiaries, (iv) guarantee certain debt, (v) make certain investments, (vi) sell or exchange certain assets, (vii) enter into transactions with affiliates, (viii) create certain liens, and (ix) consolidate, merge or transfer all or substantially all of our or our Subsidiaries’ assets. These covenants are subject to a number of exceptions, limitations and qualifications as set forth in the indenture governing the 2029 Notes.

The following table summarizes the net carrying value of the 2029 Notes as of August 1, 2026 and January 31, 2026 (dollars in thousands):


	August 1, 2026		January 31, 2026
Principal amount of 2029 Notes	$	500,000	$	500,000
Less: Debt issuance costs	(2,506)		(2,966)
Net carrying amount of 2029 Notes	$	497,494	$	497,034


	August 1, 2026		January 31, 2026
Fair value of principal amount of 2029 Notes	$	485,350	$	492,200

Significant Accounting Policies and Estimates (Policies)	6 Months Ended
	Aug. 01, 2026
Accounting Policies [Abstract]
Basis of Presentation	Dycom Industries, Inc. (“Dycom,” the “Company,” “we,” “our,” or “us”) is a leading provider of specialty contracting services focused on the digital infrastructure, telecommunications and utilities industries throughout the United States. These services include program management; planning; engineering and design; aerial, underground, and wireless construction; maintenance; and fulfillment services for telecommunications and digital infrastructure providers. We also provide underground facility locating services for various utilities, including telecommunications providers, as well as other construction and maintenance services for electric and gas utilities. Additionally, with the acquisition of Power Solutions, LLC (“Power Solutions”) in the fourth quarter of fiscal 2026 and National Technology Integrators, LLC (“National Technology Integrators”), in the second quarter of fiscal 2027, we provide comprehensive building infrastructure solutions, including electrical, energy management, inside-plant structured cabling, and advanced audio-visual, security and fire safety systems for data centers and other critical facilities. Dycom supplies the labor, tools, and equipment necessary to provide these services to its customers.
Accounting Period	Accounting Period. Our fiscal year ends on the last Saturday in January. As a result, each fiscal year consists of either 52 weeks or 53 weeks of operations (with the additional week of operations occurring in the fourth quarter). Fiscal 2027 consists of 52 weeks of operations, while fiscal 2026 consisted of 53 weeks of operations.
Segment Information	Segment Information. The Company operates in two reportable segments, Communications and Building Systems. Services are provided on a decentralized basis. Each operating segment consists of a subsidiary (or in certain instances, the combination of two or more subsidiaries), whose results are regularly reviewed by the Company’s Chief Executive Officer, the chief operating decision maker (“CODM”). All of the Company’s Communications operating segments have been aggregated into one reportable segment based on their similar economic characteristics, nature of services and production processes, type of customers, and service distribution methods. During fiscal 2026, following the acquisition of Power Solutions, the CODM reevaluated the Company’s reportable segments, which resulted in the addition of the Building Systems segment as a component of management’s internal financial information used for operational decision-making. Beginning in fiscal 2026, the Company reports the results of the Building Systems segment separately as a reportable segment. The Building Systems segment specializes in providing comprehensive building infrastructure solutions, including electrical, energy management, inside-plant structured cabling, and advanced audio-visual, security and fire safety systems for data centers and other critical facilities. See Note 20, Segment Reporting, for additional information.
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the amounts reported in these condensed consolidated financial statements and accompanying notes. These estimates are based on our historical experience and management’s understanding of current facts and circumstances. At the time they are made, we believe that such estimates are fair when considered in conjunction with the Company’s consolidated financial position and results of operations taken as a whole. However, actual results could differ materially from those estimates.
Per Share Data	Per Share Data. Basic earnings per common share is computed based on the weighted average number of common shares outstanding during the period, excluding unvested restricted share units. Diluted earnings per common share includes the weighted average number of common shares outstanding during the period and dilutive potential common shares arising from our stock-based awards (including unvested restricted share units) if their inclusion is dilutive under the treasury stock method. Common stock equivalents related to stock-based awards are excluded from diluted earnings per common share calculations if their effect would be anti-dilutive.
Leases	Leases. Prior to the acquisition of National Technology Integrators during the three months ended August 1, 2026, our lease population consisted solely of operating leases. See Note 5, Acquisitions, for information on our recent acquisition. We account for our leases as either finance or operating leases when the initial lease term is greater than 12 months. The lease term may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Leases with an initial term of 12 months or less are not recorded on our consolidated balance sheet. The right-of-use assets for finance leases are included on our consolidated balance sheet in property and equipment, net of accumulated depreciation, with a corresponding amount recorded in current portion of debt or long-term debt, as appropriate. The finance lease assets are amortized on a straight-line basis over the lease term and included in depreciation expense. The financing component associated with finance lease obligations is included in interest expense. As our finance leases were part of the National Technology Integrators acquisition, we used our incremental borrowing rate based on the information available at the acquisition date in determining the present value of the remaining lease payments. Operating leases are included in operating lease right-of-use assets and corresponding operating lease liabilities. Operating lease right-of-use assets represent our right to use the underlying asset for the lease term and operating lease liabilities represent our obligation to make the related lease payments. These assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As our operating leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards None. Accounting Standards Not Yet Adopted Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. In November 2024, the FASB issued ASU 2024-03, Income Statement (Subtopic 220-40): Disaggregation of Income Statement Expenses. This ASU requires public entities to disclose, in the notes to the financial statements, specified information about certain costs and expenses at each interim and annual reporting period. In January 2025, the FASB issued ASU 2025-01, Income Statements (Subtopic 220-40): Clarifying the Effective Date. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the impact of the standard on our condensed consolidated financial statements. Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The ASU modernizes the approach for internal-use software by eliminating the previous stage-based capitalization model so that the guidance is neutral to different software development projects. Entities may apply the guidance using a prospective, retrospective or modified transition approach. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027. We are currently evaluating the impact of the standard on our condensed consolidated financial statements. All other new accounting pronouncements that have been issued but not yet effective are currently being evaluated and at this time are not expected to have a material impact on our financial position or results of operations.

Accounts Receivable, Contract Assets, and Contract Liabilities

Accounts Receivable, Contract Assets, and Contract Liabilities

6 Months Ended

Aug. 01, 2026

Receivables [Abstract]

The following provides further details on the balance sheet accounts of accounts receivable, net; contract assets; and contract liabilities.

Accounts Receivable

Accounts receivable, net, classified as current, consisted of the following (dollars in thousands):


	August 1, 2026		January 31, 2026
Trade accounts receivable	$	787,491	$	699,904
Unbilled accounts receivable	1,334,390		880,364
Retainage	159,162		119,321
Total	2,281,043		1,699,589
Less: allowance for credit losses	(3,239)		(2,616)
Accounts receivable, net	$	2,277,804	$	1,696,973

We maintain an allowance for estimated losses on uncollected balances. The allowance for credit losses changed as follows (dollars in thousands):


	For the Three Months Ended				For the Six Months Ended
	August 1, 2026		July 26, 2025		August 1, 2026		July 26, 2025
Allowance for credit losses at beginning of period	$	2,886	$	825	$	2,616	$	1,094
Provision for bad debt	151		1,770		431		1,600
Amounts charged against the allowance, net of recoveries	202		—		192		(99)
Allowance for credit losses at end of period	$	3,239	$	2,595	$	3,239	$	2,595

Contract Assets and Contract Liabilities

Net contract (liabilities) assets consisted of the following (dollars in thousands):


	August 1, 2026		January 31, 2026
Contract assets	$	221,211	$	162,327
Contract liabilities	241,223		158,503
Contract (liabilities) assets, net	$	(20,012)	$	3,824

The change in contract (liabilities) assets, net, primarily resulted from up-front or advance billings to our customers for construction projects which are in progress, as well as increased billings, net of payments made, under contracts consisting of multiple tasks and the addition of balances from the acquisition completed during fiscal 2027. During the three and six months ended August 1, 2026, we performed services and recognized $22.7 million and $145.4 million of contract revenues related to contract liabilities that existed at January 31, 2026.

Customer Credit Concentration


	August 1, 2026			January 31, 2026
	Amount		% of Total	Amount		% of Total
AT&T Inc. (1)	$	247.4	11.0%	$	153.4	9.0%
Charter Communications, Inc.	$	204.3	9.1%	$	246.4	14.5%
Lumen Technologies, Inc. (1)	$	301.4	13.4%	$	259.0	15.2%
Verizon Communications, Inc. (2)	$	241.9	10.7%	$	173.6	10.2%

We believe that none of our significant customers were experiencing financial difficulties that would materially impact the collectability of our total accounts receivable and contract assets, net, as of August 1, 2026 or January 31, 2026.

Business Combination, Asset Acquisition, Transaction between Entities under Common Control, and Joint Venture Formation [Abstract]

Acquisitions

6 Months Ended

Aug. 01, 2026

Acquisitions

Fiscal 2027. During the second quarter of fiscal 2027, we acquired National Technology Integrators, a low-voltage engineering and construction firm based in Maryland. This acquisition expands our service offerings and our customer base. The purchase price is valued at $275.0 million as of the signing of the acquisition on a cash-free, debt-free basis. The value is subject to post-closing adjustment, including the final determination of cash, indebtedness, transaction expenses, and working capital balances. At the closing date, the funding of the acquisition included a cash payment of $226.4 million ($225.4 million net of cash acquired of $1.0 million), the issuance of 95,550 shares of Dycom common stock to the sellers valued at $45.0 million, and the assumption of seller indebtedness of $12.3 million. Total consideration was $271.4 million. National Technology Integrators is reported as part of the Company’s Building Systems segment. The purchase price allocation for this business is preliminary and will be completed when valuations for intangible assets and other amounts are finalized within the 12-month measurement period from the date of acquisition.

Fiscal 2026. During the fourth quarter of fiscal 2026, we acquired Power Solutions, LLC (“Power Solutions”), a company that provides comprehensive building infrastructure solutions, including electrical, energy management, security, and fire safety systems for data centers and other critical facilities in the Greater Washington D.C., Maryland, and Virginia area. This acquisition expands our service offerings and our customer base. The purchase price was valued at $1.95 billion as of the signing of the acquisition on a cash-free, debt-free basis. The value was subject to post-closing adjustment, including the final determination of cash, indebtedness and working capital balances. At the closing date, the funding of the acquisition included a cash payment of $1,644.9 million ($1,628.6 million net of cash acquired of $16.3 million), the issuance of 1,011,069 shares of Dycom common stock to the sellers valued at $351.0 million, and the assumption of seller indebtedness of $64.8 million. A post-closing working capital adjustment of $12.8 million was recorded during the first quarter of fiscal 2027. Total consideration was $2,008.7 million. The acquisition of Power Solutions resulted in the addition of a new operating segment which is also a new reportable segment – Building Systems. For additional information on our reportable segments, see Note 20, Segment Reporting. The purchase price allocation for this business is preliminary and will be completed when valuations for intangible assets and other amounts are finalized within the 12-month measurement period from the date of acquisition.

The purchase price of the acquired companies was allocated based on the fair value of the assets acquired and the liabilities assumed on the date of acquisition. The excess purchase price over the estimated fair value of the net assets acquired was recognized as goodwill.

The following table summarizes the aggregate consideration paid and the estimated fair value of assets acquired and liabilities assumed for each acquisition described above as of their respective acquisition dates (dollars in millions):


	Fiscal 2027		Fiscal 2026
Assets
Cash and equivalents	$	1.0	$	16.3
Accounts receivable	80.8		324.2
Contract assets	2.1		18.9

Other current assets	1.5		1.8
Property and equipment	5.8		8.4
Goodwill	141.9		1,124.4
Intangible assets	128.2		775.0
Other assets	23.0		16.9
Total assets	384.3		2,285.9

Liabilities
Accounts payable	15.0		56.4
Current portion of debt	9.5		—
Contract liabilities	56.3		116.2
Other accrued liabilities	7.6		90.0
Other liabilities	24.5		14.6
Total liabilities	112.9		277.2

Net Assets Acquired	$	271.4	$	2,008.7

The excess purchase price over the estimated fair value of the net assets acquired was recognized as goodwill. Goodwill and intangible assets total $270.1 million and $1,899.4 million for the 2027 and 2026 acquisitions, respectively and are deductible for tax purposes. Accounts receivable, contract assets (liabilities) and current liabilities were either stated at their historical carrying values, which approximate fair value given the short-term nature of these assets and liabilities, or were stated at their fair values based on an evaluation of the current market value of such assets and liabilities. The estimate of fair value for fixed assets was based on an assessment of acquired assets’ condition as well as an evaluation of the current market value of such assets.

The Company recorded intangible assets based on its estimate of fair value which consisted of the following (dollars in millions):


	Estimated Useful Life (in years)	Intangible Assets Acquired in fiscal 2027		Intangible Assets Acquired in fiscal 2026
Customer relationships	15.0	$	88.8	$	580.0

Backlog intangibles	1.5	39.4		155.0
Trade names	15.0	—		40.0
Total intangible assets acquired		$	128.2	$	775.0

The valuation of intangible assets was determined using the income approach methodology. More specifically, the fair values of the customer relationships and the backlog intangibles were estimated using the multi-period excess earnings method, while the trade name was estimated using the relief-from-royalty method. Significant judgments and assumptions used in estimating management’s cash flow projections included projected revenue growth rates, profit margins, discount rates, customer attrition rates and royalty rates among others. The projected future cash flows are discounted to present value using an appropriate discount rate.

Results of the businesses acquired are included in our condensed consolidated financial statements from their respective dates of acquisition and represent the newly formed Building Systems reportable segment. For additional information on our reportable segments, including the results of the Building Systems segment, see Note 20, Segment Reporting.

The pro forma results for the acquisition completed during fiscal 2027 have been excluded as the impact was not material to the Company’s consolidated financial statements. The following unaudited supplemental pro forma results of operations for the Company, which incorporate the acquisition completed in fiscal 2026, have been provided for illustrative purposes only and may not be indicative of the actual results that would have been achieved by the combined companies for the periods presented or that may be achieved by the combined companies in the future (dollars in thousands).


	For the Three Months Ended				For the Six Months Ended
	August 1, 2026		July 26, 2025		August 1, 2026		July 26, 2025
Contract revenues	$	2,005,907	$	1,644,536	$	3,970,689	$	3,121,070
Net income	115,637		87,554		206,926		124,209

The pro forma combined results of operations for the three and six months ended July 26, 2025 were prepared by adjusting the historical results of Dycom to include the historical results of the business acquired in fiscal 2026 as if such acquisition had occurred at the beginning of fiscal 2025. These pro forma combined historical results were adjusted for the following: an increase in interest and other financing expenses as a result of the debt incurred by Dycom for the purpose of financing the acquisition of Power Solutions and cash consideration paid for the acquired business and an increase in amortization expense due to the intangible assets recorded. The pro forma combined results of operations do not include any adjustments to eliminate the impact of acquisition-related costs incurred by Dycom or the acquired business or any cost savings or other synergies that resulted or may result from the acquisitions.

The entire disclosure for business combination.

Basis of Presentation	6 Months Ended
Basis of Presentation	Aug. 01, 2026
Basis of Presentation [Abstract]
Basis of Presentation	Basis of Presentation Dycom Industries, Inc. (“Dycom,” the “Company,” “we,” “our,” or “us”) is a leading provider of specialty contracting services focused on the digital infrastructure, telecommunications and utilities industries throughout the United States. These services include program management; planning; engineering and design; aerial, underground, and wireless construction; maintenance; and fulfillment services for telecommunications and digital infrastructure providers. We also provide underground facility locating services for various utilities, including telecommunications providers, as well as other construction and maintenance services for electric and gas utilities. Additionally, with the acquisition of Power Solutions, LLC (“Power Solutions”) in the fourth quarter of fiscal 2026 and National Technology Integrators, LLC (“National Technology Integrators”), in the second quarter of fiscal 2027, we provide comprehensive building infrastructure solutions, including electrical, energy management, inside-plant structured cabling, and advanced audio-visual, security and fire safety systems for data centers and other critical facilities. Dycom supplies the labor, tools, and equipment necessary to provide these services to its customers. Accounting Period. Our fiscal year ends on the last Saturday in January. As a result, each fiscal year consists of either 52 weeks or 53 weeks of operations (with the additional week of operations occurring in the fourth quarter). Fiscal 2027 consists of 52 weeks of operations, while fiscal 2026 consisted of 53 weeks of operations. The accompanying unaudited condensed consolidated financial statements of the Company and its subsidiaries, all of which are wholly-owned, have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements and should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in this report and the Company’s audited financial statements included in the Company’s Annual Report on Form 10-K for fiscal 2026, filed with the SEC on March 9, 2026. In the opinion of management, all adjustments considered necessary for a fair statement of the results for the interim periods presented have been included. This includes all normal and recurring adjustments and elimination of intercompany accounts and transactions. Operating results for the interim period are not necessarily indicative of the results expected for any subsequent interim or annual period. Segment Information. The Company operates in two reportable segments, Communications and Building Systems. Services are provided on a decentralized basis. Each operating segment consists of a subsidiary (or in certain instances, the combination of two or more subsidiaries), whose results are regularly reviewed by the Company’s Chief Executive Officer, the chief operating decision maker (“CODM”). All of the Company’s Communications operating segments have been aggregated into one reportable segment based on their similar economic characteristics, nature of services and production processes, type of customers, and service distribution methods. During fiscal 2026, following the acquisition of Power Solutions, the CODM reevaluated the Company’s reportable segments, which resulted in the addition of the Building Systems segment as a component of management’s internal financial information used for operational decision-making. Beginning in fiscal 2026, the Company reports the results of the Building Systems segment separately as a reportable segment. The Building Systems segment specializes in providing comprehensive building infrastructure solutions, including electrical, energy management, inside-plant structured cabling, and advanced audio-visual, security and fire safety systems for data centers and other critical facilities. See Note 20, Segment Reporting, for additional information.

Supplier Finance Program

6 Months Ended

Aug. 01, 2026

Supplier Finance Program

Beginning in the fourth quarter of fiscal 2026, the Company has provided certain suppliers with access to a supplier finance program administered through a third party, which facilitates participating suppliers’ ability to finance payments due from the Company through third-party financial institutions. Participating suppliers may, at their sole discretion, receive payment of the Company’s obligation prior to the scheduled due dates, at a discounted price from the third party. The Company agrees to pay the financial institution the stated amount generally within 60 days of receipt of the invoice. The Company’s obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by the supplier’s decision to finance amounts under these arrangements. The Company does not have pledged assets or other guarantees under the program. Our outstanding payment obligations are included in accounts payable on our consolidated balance sheets and are reported as operating activities in our consolidated statements of cash flows when paid.

The following table presents the change in the supplier financing obligation for the three and six months ended August 1, 2026 (dollars in millions):


	For the Three Months Ended				For the Six Months Ended

Segment Reporting

Segment Reporting [Abstract]

Segment Reporting

The Company operates in two reportable segments which derive revenues by providing specialty contracting services throughout the United States on a decentralized basis. Dycom’s reportable segments are: Communications and Building Systems. This segment structure reflects the financial information and reports used by the Company's Chief Executive Officer, the chief operating decision maker (CODM), to make decisions regarding the Company's business, including performance assessments and strategic and operational planning in compliance with ASC 280, Segment Reporting.

Communications. The Communications segment provides specialty contracting services, including program management, planning; engineering and design; aerial, underground, and wireless construction; maintenance; and fulfillment services for telecommunications and digital infrastructure providers. The Communications segment also provides underground facility locating services for various utilities and other construction and maintenance services for electric and gas utilities. The Communications segment services are provided by its operating segments that consist of a subsidiary (or in certain instances, the combination of two or more subsidiaries), whose results are regularly reviewed by the CODM. The Communications segment’s operating segments have been aggregated into one reportable segment based on their similar economic characteristics, nature of services and production processes, type of customers, and service distribution methods.

Building Systems. During fiscal 2026, following the acquisition of Power Solutions, the CODM reevaluated the Company’s reportable segments, which resulted in the addition of the Building Systems segment as a component of management’s internal financial information used for operational decision-making. Beginning in fiscal 2026, the Company has reported the results of the Building Systems segment separately as a reportable segment. The Building Systems segment reflects the results of Power Solutions following the acquisition on December 23, 2025 and National Technology Integrators following the acquisition on July 2, 2026. The Building Systems segment specializes in providing comprehensive building infrastructure solutions, including electrical, energy management, inside-plant structured cabling, and advanced audio-visual, security and fire safety systems for data centers and other critical facilities.

The key measure of segment profit or loss utilized by the CODM to assess performance of and allocate resources to the Company’s operating segments is income before income taxes. Significant segment expenses included in income before income taxes are cost of earned revenues, depreciation and amortization, and other segment items, which include general and administrative expenses, segment interest expense (income) and other income (expense). The measure of segment assets regularly provided to the CODM is consistent with total assets as reported on the consolidated balance sheets.

The CODM reviews contract revenues and income before income taxes compared to historical, forecasted and budgeted amounts to assess the performance of the Company’s operating segments and allocate resources.

Certain corporate costs are not allocated, including certain acquisition and integration costs, credit agreement and senior notes interest expense, interest income on invested balances and loss on debt extinguishment.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies From time to time, we are party to various claims and legal proceedings arising in the ordinary course of business. While the resolution of these matters cannot be predicted with certainty, it is the opinion of management, based on information available at this time, that the ultimate resolution of any such claims or legal proceedings will not, after considering applicable insurance coverage or other indemnities to which we may be entitled, have a material effect on our financial position, results of operations, or cash flow. Commitments Performance and Payment Bonds and Guarantees. We have obligations under performance and other surety contract bonds related to certain of our customer contracts. Performance bonds generally provide a customer with the right to obtain payment and/or performance from the issuer of the bond if we fail to perform our contractual obligations. As of August 1, 2026 and January 31, 2026, we had $1,215.8 million and $917.9 million, respectively, of outstanding performance and other surety contract bonds. In addition to performance and other surety contract bonds, as part of our insurance program we also provide surety bonds that collateralize our obligations to our insurance carriers. As of August 1, 2026 and January 31, 2026, we had $43.8 million and $31.0 million, respectively, of outstanding surety bonds related to our insurance obligations. Additionally, we have periodically guaranteed certain obligations of our subsidiaries, including obligations in connection with obtaining state contractor licenses and leasing real property and equipment. Letters of Credit. We have issued standby letters of credit under our credit agreement that collateralize our obligations to our insurance carriers. As of August 1, 2026 and January 31, 2026, we had $53.6 million of outstanding standby letters of credit issued under our credit agreement.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective income tax rate was 24.9% and 25.7% for the three months ended August 1, 2026 and July 26, 2025, respectively and 20.6% and 24.4% for the six months ended August 1, 2026 and July 26, 2025, respectively. The interim income tax provisions are based on the effective income tax rate expected to be applicable for the full fiscal year, adjusted for specific items that are required to be recognized in the period in which they occur. The effective tax rate differs from the statutory rate primarily due to the difference in income tax rates from state to state where work was performed, non-deductible and non-taxable items, tax credits recognized, the tax effects of the vesting and exercise of share-based awards, and changes in unrecognized tax benefits. Deferred tax assets and liabilities are based on the enacted tax rate that will apply in future periods when such assets and liabilities are expected to be settled or realized.

The entire disclosure for income tax.
