Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Prior to August 11, 2025, the Company was also an operating segment of Southwest Gas Holdings. The Company’s consolidated financial statements have been prepared on a standalone basis. The consolidated statements of operations include all revenues and costs directly attributable to Centuri’s operations. The consolidated statements of operations also include an allocation of expenses related to certain Southwest Gas Holdings corporate functions, including corporate governance, internal audit, tax compliance and other general and administrative cost. The Company’s use of shared service support from Southwest Gas Holdings and the associated expense allocation decreased following the Centuri IPO in April 2024, and materially ceased following the Final Disposition in September 2025. For more information regarding related party transactions with Southwest Gas Holdings, including the amount of expenses historically allocated, see “Note 17 — Related Parties”. The Company believes the allocation methodology is reasonable for all periods presented. However, the allocations may not reflect the expenses the Company would have incurred as a standalone public entity for the periods presented. A number of factors, including the chosen organizational structure, division between outsourced and in-house functions and strategic decisions, would impact the actual costs incurred by the Company. The Company has determined that it is not practicable to determine these standalone costs for the periods presented. As a result, the consolidated financial statements are not indicative of the Company’s financial condition, results of operations or cash flows had it operated as a standalone public entity during the periods presented, and results in the consolidated financial statements are not indicative of the Company’s future financial condition, results of operations or cash flows. Income tax amounts in the consolidated financial statements for fiscal years 2024 and 2023 were calculated using the separate return method and presented as if the Company’s operations were separate taxpayers in their respective jurisdictions, which may or may not have reflected the actual tax filing positions of the Company. Income tax amounts in the consolidated financial statements for fiscal year 2025 include the allocation of certain tax assets as part of income tax deconsolidation from Southwest Gas Holdings, as discussed further in “Income Taxes” below.
Fiscal Period	The Company uses a 52/53-week fiscal year that ends on the Sunday closest to the end of the calendar year. Unless otherwise stated, references to years in the Company’s consolidated financial statements relate to fiscal years rather than calendar years. Unless the context otherwise requires, references to 2025, 2024, and 2023 refer to the fiscal years ended December 28, 2025, December 29, 2024 and December 31, 2023, respectively. Fiscal years 2025, 2024, and 2023 each had 52 weeks.
Principles of Consolidation and Noncontrolling Interests	Principles of Consolidation and Noncontrolling Interests The accompanying consolidated financial statements reflect the accounts of the Company, all majority-owned subsidiaries and variable interest entities in which the Company or a subsidiary is the primary beneficiary. All intercompany transactions and balances have been eliminated. The Company is required to perform an analysis each reporting period to determine if it is the primary beneficiary of any company that meets the definition of a variable interest entity (“VIE”). The determination of the primary beneficiary is focused on identifying which enterprise has both the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or receive benefits from the VIE. See “Note 7 — Equity Method Investments” for more information. The Company also reports a separate component within temporary equity in the consolidated financial statements for the redeemable common stock associated with the minority position related to Riggs Distler & Company, Inc. (“Riggs Distler”), which also represents a noncontrolling interest (“NCI”). The balance of redeemable common stock is reported as the greater of the carrying amount or fair market value.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. The Company reviews all significant estimates affecting its consolidated financial statements on a recurring basis and records the effect of any necessary adjustments in the applicable period. These estimates are based on management’s best knowledge of current events, historical experience, actions that the Company may undertake in the future and various other assumptions that are believed to be reasonable under the circumstance. As a result, actual results could differ from those estimates. Significant estimates in the consolidated financial statements include: useful lives of property and equipment and identifiable intangible assets; the fair value assumptions in analyzing property and equipment, identifiable intangible assets, goodwill, and redeemable noncontrolling interests; allowances for doubtful accounts; revenue recognized under fixed-price contracts; accrued compensation; provision for income taxes; uncertain tax positions; and estimates and assumptions used in the accounting for business combinations.
Revenue Recognition	Revenue Recognition The Company derives revenue primarily through its diverse array of service solutions to North America’s gas and electric utility providers. Electric power infrastructure services also include storm restoration services, including the repair of infrastructure damaged by inclement weather, and the energized installation, maintenance and upgrade of electric power infrastructure. In addition, the Company performs certain industrial and other construction services for various customers and industries. The Company generally has two types of agreements with its customers: master services agreements (“MSAs”) and bid contracts. An MSA identifies most of the terms describing each party’s rights and obligations that will govern future work authorizations. An MSA is often effective for multiple years. A work authorization is issued by the customer to describe the location, timing, unit of work and any additional information necessary to complete the work for the customer. The combination of the MSA and the work authorization determines when a contract exists and revenue recognition may begin. Each work authorization is generally a single performance obligation as the Company is performing a significant integration service. The Company utilizes the portfolio method practical expedient at the customer level as the terms and conditions of MSAs are similar in nature for each customer, but the actual services provided can vary significantly between customers. A bid contract is typically a one-time agreement for a specific project that has all necessary terms defining each party’s respective rights and obligations. Each bid contract is evaluated for revenue recognition individually. Control of assets created under bid contracts generally passes to the customer over time. Bid contracts often have a single performance obligation as the Company is performing a significant integration service. For revenue recognition purposes, the Company’s MSAs and bid contracts are characterized as either unit-price, time-and-materials (“T&M”) or fixed-price. The majority of the Company’s work is performed under unit-price contracts, which generally state prices per unit of installation, or T&M contracts, which are billed as labor hours are incurred, materials are utilized and services are performed. For unit-price and T&M contracts, an output method is used to measure progress towards satisfaction of a performance obligation. Typical installations are accomplished in a few weeks or less, with revenue recorded as units are completed and services are performed. Some unit-price contracts contain caps that, if encroached, trigger revenue and loss recognition similar to a fixed-price contract model. Performance obligations related to fixed-price contracts are satisfied over time because the Company’s performance typically creates or enhances an asset that the customer controls. The Company recognizes revenue on its fixed-price contracts as performance obligations are satisfied and control of the promised good and/or service is transferred to the customer by measuring the progress toward complete satisfaction of the performance obligation(s) using an input method. The input method results in the recognition of revenue based on the Company’s effort to satisfy the performance obligation relative to the total expected effort to satisfy the performance obligation. The Company uses the cost-to-cost input method to measure progress towards the satisfaction of the performance obligation in fixed-price contracts. Under the cost-to-cost input method, costs incurred to-date are generally the best depiction of transfer of control; therefore, the amount of revenue recognized on fixed-price contracts is based on costs expended to date relative to the anticipated final contract costs. All contract costs, including those associated with affirmative claims, change orders and back charges, are recorded as incurred and revisions to estimated total costs are reflected as soon as the obligation to perform is determined. Contract costs consist of direct costs on contracts, including labor and materials, amounts payable to subcontractors, direct overhead costs and equipment expense (primarily depreciation, fuel, maintenance and repairs). Most of the Company’s customers supply many of their own materials in order for the Company to complete its work under the contracts. Actual revenue and project costs can vary, sometimes substantially, from previous estimates due to changes in a variety of factors, including unforeseen circumstances not originally contemplated. These factors, along with other risks inherent in performing fixed-price contracts, may cause actual revenue and gross profit for a project to differ from previous estimates and could result in reduced profitability or losses on projects. Changes in these factors may result in revisions to costs and earnings. Revisions in estimates of costs and earnings during the course of work are reflected in the accounting period in which the facts requiring revision become known. At the time a loss on a contract becomes known or is anticipated, the entire amount of the estimated ultimate loss is recognized in the consolidated financial statements. Once identified, these types of conditions continue to be evaluated for each project throughout the project term, and ongoing revisions in management’s estimates of contract value, contract cost and contract profit are recognized as necessary in the period determined. Subsequent to the inception of a fixed-price contract, the transaction price could change for various reasons, including the executed or estimated amount of change orders and unresolved contract modifications and claims to or from customers. Changes that are accounted for as an adjustment to existing performance obligations are allocated on the same basis as established at contract inception. Otherwise, changes are accounted for as a separate performance obligation(s) and the separate transaction price is allocated as discussed above. Contracts can have consideration that is variable. For MSAs, variable consideration is evaluated at the customer level as the terms creating variability in pricing are included within the MSA and are not specific to a work authorization. For multi-year MSAs, variable consideration items are typically determined for each year of the contract and not for the full contract term. For bid contracts, variable consideration is evaluated at the individual contract level. The expected value method or most likely amount method is used based on the nature of the variable consideration. Types of variable consideration include liquidated damages, delay penalties, performance incentives, safety bonuses, payment discounts and volume rebates. The Company will estimate variable consideration and adjust financial information as necessary. Change orders may involve a modification in scope, price, or both to the current contract, and are typically agreed to in writing by both parties. Once approved, the change order is either treated as a separate contract or as part of the existing contract as appropriate under the circumstances. When the scope is agreed upon in the change order but not the price, the Company estimates the change to the transaction price. On occasion, the Company recognizes revenue related to contract claims and unapproved change orders. Contract claims and unapproved change orders occur when there is a dispute between the Company and a customer regarding a change in the scope of work and associated price for work already performed, and/or when the Company otherwise performs work above the scope of the initial contract without a formally executed change order. The Company records estimated claims and unapproved change orders as variable consideration based on the most likely amount it expects to receive, and to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company is required to collect taxes imposed by various governmental agencies on the work performed for its customers. These taxes are not included in revenue. Management uses the net classification method to report taxes collected from customers to be remitted to governmental authorities.
Fair Value Measurements	Fair Value Measurements The Company categorizes assets and liabilities, measured at fair value, into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 inputs are quoted prices for identical instruments in active markets. Level 2 inputs are quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs or significant value-drivers are observable. Level 3 inputs are model-derived valuations in which one or more significant inputs or significant value-drivers are unobservable. Fair value measurements are classified according to the lowest level input or value-driver that is significant to the valuation. The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable, contract assets, book overdrafts, accounts payable, contract liabilities and accrued liabilities approximate fair value because of the short-term nature of these financial instruments.
Cash and Cash Equivalents	Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents primarily consist of interest-bearing demand deposits. The Company considers highly liquid investments with original maturities of less than three months, including the Company’s investments in money market funds, to be cash equivalents.
Restricted Cash	Restricted cash consists of cash owned by the Company that is subject to legal restrictions on its use. Restricted cash is classified as either prepaid expenses and other current assets or other assets on the consolidated balance sheets depending on whether the Company expects to use the cash within the next fiscal year.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Amounts due from customers are recorded at face amounts less an allowance for doubtful accounts. The allowance is an estimate based on historical collection experience, current and estimated future economic and market conditions, and a review of the current status of each customer’s trade accounts receivable balance. Account balances are charged against the allowance when management determines it is probable that the receivable will not be recovered. Accounts receivable, net, includes only amounts that are unconditional in nature, which means only the passage of time remains and the Company has invoiced the customer. The Company is currently party to an accounts receivable securitization facility whereby it sells accounts receivable to a third-party financial institution. In accordance with ASC 860, “Transfers and Servicing,” the Company derecognizes accounts receivables sold through this facility due to its limited continuing involvement with the accounts receivable after sale. Refer to “Note 6 — Accounts Receivable Securitization Facility” for further details regarding this facility.
Long-Lived Assets	Long-Lived Assets Property and equipment are recorded at cost and include all costs necessary to bring the asset to its intended use. Expenditures for repairs and maintenance are expensed as incurred. Expenditures for major renewals or improvements that extend the useful life of existing equipment are capitalized and depreciated over the remaining useful life of the asset. Property and equipment include the costs of on-premise software purchased or developed for internal use. Software costs are capitalized when the preliminary project stage is complete and the Company authorizes and commits to funding the project. Software costs cease to be capitalized once all substantial testing is completed. Upgrades and enhancements of internal use software are only capitalized to the extent they will result in additional functionality. Depreciation is computed using the straight-line method based on the estimated useful lives and salvage values of the related assets. Depreciation expense is recognized as a component of cost of sales or selling and general and administrative expenses within the consolidated statements of operations depending on the nature of the asset being depreciated. When the Company disposes of property and equipment it recognizes a gain or loss in the statements of operations, which is the result of any proceeds less the net book value of the asset being disposed. The gain or loss on disposition of assets is recognized as a component of cost of revenue or selling, general and administrative expenses within the consolidated statements of operations depending on the nature of the asset being disposed.
Hosting Arrangements	The Company enters into certain cloud-based software hosting arrangements that are accounted for as service contracts (cloud computing arrangements or “CCAs”). The Company may incur and capitalize certain implementation costs to integrate, configure, and customize software as part of these CCAs, which is consistent with the Company’s capitalization of costs incurred during the application development stage for on-premise software. CCA implementation costs are capitalized within other assets within the consolidated balance sheets and expensed on a straight-line basis over the fixed, noncancellable term of the associated hosting arrangements plus any reasonably certain renewal periods.
Long-Lived Asset Impairment	Long-Lived Asset Impairment The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. When an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset’s carrying amount to determine if an impairment is necessary. Any impairment loss recognized is equal to the amount by which the carrying amount of the asset exceeds its fair value. For fiscal years 2025, 2024, and 2023, the Company did not recognize any significant impairment related to its long-lived assets.
Goodwill	Goodwill Goodwill represents the excess of cost over the fair market value of net tangible and identifiable intangible assets of acquired businesses and is stated at cost. The Company has recorded goodwill in connection with certain of its business acquisitions. Goodwill is required to be measured for impairment at the reporting unit level, which represents the operating entity level or one level below the operating entity level for which discrete financial information is available. Goodwill is tested for impairment annually on the first day of the fourth fiscal quarter, or more frequently if events or circumstances arise which indicate that the fair value of a reporting unit with goodwill is below its carrying amount. The Company assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. Qualitative factors assessed for each reporting unit include, among other things, deterioration in macroeconomic conditions; declining financial performance; deterioration in the operational environment; a significant change in market, management, business strategy or business climate; a loss of a significant customer; increased competition; or a decrease in the estimated fair value of a reporting unit. If the Company believes that, as a result of its qualitative assessment, it is more likely than not that the fair value of a reporting unit is less than its carrying amount, a quantitative impairment test is required. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recorded in the consolidated statements of operations.
Business Combinations	Business Combinations The Company accounts for business combinations using the acquisition method of accounting, which requires that the purchase price, including the fair value of contingent consideration, of the acquired entity to be allocated to the assets acquired and liabilities assumed based generally on the estimated fair values at the date of acquisition. Any excess of the purchase price over the estimated fair value of the identifiable net assets acquired is recorded as goodwill. Acquisition-related expenses and transaction costs associated with business combinations are expensed as incurred. The determination of the fair value of assets acquired and liabilities assumed requires the Company to make subjective judgments as to projections of future operating performance, discount rates, and long-term growth rates, among other factors, which are typically level 3 inputs. The effect of these judgments then impacts the amount of the goodwill that is recorded and the amount of depreciation and amortization expense to be recognized in future periods related to tangible and intangible assets acquired. GAAP provides a “measurement period” of up to one year in which to finalize estimates associated with the acquisition of a business. Most estimates are preliminary until the end of the measurement period. During the measurement period, adjustments to initial valuations and estimates that reflect newly discovered information that existed at the acquisition date are recorded as adjustments to the goodwill balance. After the measurement date, any adjustments would be recorded as a current period gain or loss.
Investments in Unconsolidated Affiliates	Investments in Unconsolidated Affiliates The Company’s investments in unconsolidated affiliates are investments in entities in which the Company does not have a controlling financial interest, but over which it has significant influence. Investments in unconsolidated affiliates are included in other assets on the consolidated balance sheets. The Company’s share of allocated profit or loss from unconsolidated affiliates is included in other (income) expense, net on the consolidated statements of operations. The Company’s investment in its unconsolidated affiliate is assessed for other-than-temporary impairment when events or circumstances arise that indicate it is more likely than not that the fair value of the investment is below its carrying value. There were no events or circumstances during 2025, 2024 or 2023 that would indicate an other-than-temporary decline in the value of the Company’s investment in its unconsolidated affiliate existed.
Insurance	Insurance The Company utilizes a captive insurance company to insure against the risks associated with workers’ compensation, auto liability and general liability claims. The Company pays administrative fees to certain third-party administrators and consultants and pays claims incurred on a quarterly basis. In connection with these liability insurance policies, the Company is responsible for an initial deductible or self-insured retention amount per occurrence, after which the insurance carriers would be responsible for amounts up to the policy limits. For the policy year spanning May 2025 to April 2026, the Company is responsible for the first $750,000 (deductible) per occurrence under the liability insurance policies. The Company accrues for claims based on projected future losses and associated rates, as calculated by a third-party actuary company.
Leases	Leases The Company determines if an arrangement is a lease at inception. If an arrangement is considered a lease, the Company determines at the commencement date whether the lease is an operating or finance lease. Finance leases are leases that meet any of the following criteria: the lease transfers ownership of the underlying asset at the end of the lease term; the lessee is reasonably certain to exercise an option to purchase the underlying asset; the lease term is for the major part of the remaining economic life of the underlying asset (except when the commencement date falls at or near the end of such economic life); the present value of the sum of the lease payments and any additional residual value guarantee by the lessee equals or exceeds substantially all of the fair value of the underlying asset; or the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. A lease that does not meet any of these criteria is considered an operating lease. After the commencement date, lease cost for an operating lease is recognized over the remaining lease term on a straight-line basis, while lease cost for a finance lease is based on the depreciation of the lease asset and interest on the lease liability. A right-of-use (“ROU”) asset represents the Company’s right to use an underlying asset for the lease term, and a ROU lease liability represents the Company’s obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date to determine the present value of lease payments. The Company uses the implicit rate when readily determinable. The operating and finance lease ROU assets also include any lease payments made and excludes lease incentives. The Company’s operating lease terms may include options to extend or terminate the lease when it is reasonably certain the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has elected to account for lease and non-lease components as a single lease component. Leases with an initial term of twelve months or less are classified as short-term leases and are not recognized on the consolidated balance sheets unless the lease contains a purchase option that is reasonably certain to be exercised, or unless it is reasonably certain that the equipment will be leased for greater than twelve months. For sale lease-back transactions, the Company assesses whether control of the underlying asset has transferred to determine whether the transaction qualifies as a sale.
Income Taxes	Income Taxes The Company historically was included on the U.S. federal and certain state income tax returns of Southwest Gas Holdings and calculated income tax amounts using the separate return method as if the Company was a separate taxpayer to allow users to understand the financial position of the Company as a standalone taxable entity. This resulted in the Company recording net deferred tax assets primarily related to net operating losses and interest limitations under Section 163(j) of the Internal Revenue Code of 1986, as amended, which differed from tax attributes actually generated and used by Southwest Gas Holdings as the consolidated and ultimate taxable entity. As discussed in “Note 1 — Description of Business,” Southwest Gas Holdings no longer holds an equity interest in the Company, and accordingly the Company will no longer be included in Southwest Gas Holdings’ U.S. federal and state income tax returns. As a result, certain deferred tax assets previously recorded under the separate return method were removed from the consolidated balance sheet through an adjustment to additional paid-in capital. In addition, in accordance with the Company’s Tax Assets Agreement (as defined and discussed in “Note 17 — Related Parties”) with Southwest Gas Holdings, the Company was allocated $55.4 million in estimated deferred tax assets (primarily net operating losses) during the fiscal second and third quarters of 2025 as part of income tax deconsolidation. The allocation of these assets was treated as a capital contribution from Southwest Gas Holdings in additional paid-in capital as the Company was still a subsidiary of Southwest Gas Holdings at that time. Adjustments related to the realizability of deferred tax assets contributed from Southwest Gas Holdings upon deconsolidation also impacted additional paid-in capital. In the fourth quarter of 2025, after the Company had completed income tax deconsolidation and was no longer a subsidiary of Southwest Gas Holdings, a change in Southwest Gas Holdings’ estimate of 2025 taxable income resulted in a $23.7 million increase in deferred tax assets allocable to the Company, recognized as an income tax benefit in the consolidated statement of operations. The allocation of deferred tax assets may continue to change until Southwest Gas Holdings’ 2025 tax returns are filed, with future changes impacting the statement of operations. The Company has elected to treat its Global Intangible Low-Taxed Income (“GILTI”) as a current period cost when incurred and has considered the estimated GILTI impact in its tax expense. Realization of deferred tax assets is dependent on the Company’s ability to generate sufficient taxable income of an appropriate character in future periods. A valuation allowance is established if it is determined to be more likely than not a deferred tax asset will not be realized. As of December 28, 2025 and December 29, 2024, the Company had not repatriated undistributed earnings from its Canadian subsidiaries. The Company asserts that all future earnings will be permanently reinvested in the Canadian operations. Accordingly, as of December 28, 2025, no U.S. deferred income taxes have been recorded related to cumulative foreign earnings. In assessing whether uncertain tax positions should be recognized in its financial statements, management determines whether it is more-likely-than-not that a tax position will be sustained upon examination. Interest and penalties related to uncertain income tax positions, if any, are included as a component of income tax expense on the consolidated statements of operations.
Foreign Currency Translation	Foreign Currency Translation The Company’s foreign currency-denominated assets and liabilities are translated into U.S. dollars, the Company’s functional currency, at exchange rates existing at the respective balance sheet dates. Translation adjustments resulting from fluctuations in exchange rates are recorded as a separate component of accumulated other comprehensive loss. Results of operations of foreign subsidiaries are translated using monthly weighted average exchange rates during the respective periods. During 2025, 2024, and 2023, the company recorded losses of $0.1 million, $0.1 million and $0.5 million, respectively, related to foreign currency transactions. Gains and losses resulting from foreign currency transactions are included in other income, net on the consolidated statements of operations. The comparability of the Company’s financial statements has been affected by changes in the value of the Canadian dollar in relation to the U.S. dollar. The financial statement line items most significantly impacted by foreign currency volatility are accounts receivable, contract assets and liabilities, intangible assets, goodwill and long-term debt.
Litigation	Litigation From time to time, the Company is subject to ordinary and routine legal proceedings related to the usual conduct of its business. Accruals for such contingencies are recorded to the extent the Company concludes their occurrence is probable and the financial impact of an adverse outcome is reasonably estimable. Legal fees are recognized as incurred and are not included in accruals for contingencies. Specific legal contingencies are disclosed if the likelihood of occurrence is at least reasonably possible, and the exposure is considered material to the consolidated financial statements. In making determinations of likely outcomes of litigation matters, many factors are considered. These factors include, but are not limited to, past history, applicable evidence (and the relative weight thereof), facts and circumstances, the relevant law and the specifics and status of each matter. If the assessment of various factors changes, the estimates may change. Predicting the outcome of claims and litigation and estimating related costs and exposure involves substantial uncertainties that could cause actual costs to vary materially from estimates and accruals. See “Note 18 — Commitments and Contingencies” for more information on current legal proceedings.
Collective Bargaining Agreements	Collective Bargaining Agreements As of December 28, 2025, approximately 57% of the Company’s employees, primarily consisting of craft tradespeople, were covered by collective bargaining agreements. Of the 332 collective bargaining agreements to which the Company is a party, 27 expire during 2026 and 14 expire during 2027 and require renegotiation. The Company’s management and union leadership will determine if there is a need to renegotiate the terms and conditions of these contracts. Although the majority of these agreements prohibit strikes and work stoppages during the term of the agreement, the Company cannot be certain strikes or work stoppages will not occur in the future. Strikes or work stoppages could adversely impact the Company’s relationships with its customers and could have an adverse effect on its business.
Earnings (Loss) Per Share	Earnings (Loss) Per Share The Company computes earnings (loss) per share using the treasury stock method. Under the treasury stock method, basic earnings (loss) per share are computed by dividing net income (loss) attributable to common stock by the weighted average number of common shares outstanding during the period, and diluted earnings (loss) per share are computed by dividing net income (loss) attributable to common stock by the weighted average number of common shares outstanding during the period plus all potentially dilutive common stock equivalents, except in cases where the effect of the common stock equivalent would be anti-dilutive.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Guidance In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The update enhances income tax disclosure requirements. This update became effective for the Company beginning with this Annual Report, and is reflected on a prospective basis within “Note 14 — Income Taxes”. New Accounting Pronouncements Not Yet Adopted In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” The update enhances the level of detail available related to reporting about expenses. This update will be effective for the Company beginning with the annual reporting for the fiscal year ending 2027. The Company is currently evaluating the impact the rules will have on its disclosures. There are no other recently issued accounting standards updates that are currently expected to be adopted or material to the Company effective in fiscal 2025 or thereafter.

Basis of Presentation and Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 28, 2025

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Prior to August 11, 2025, the Company was also an operating segment of Southwest Gas Holdings. The Company’s consolidated financial statements have been prepared on a standalone basis.

The consolidated statements of operations include all revenues and costs directly attributable to Centuri’s operations. The consolidated statements of operations also include an allocation of expenses related to certain Southwest Gas Holdings corporate functions, including corporate governance, internal audit, tax compliance and other general and administrative cost. The Company’s use of shared service support from Southwest Gas Holdings and the associated expense allocation decreased following the Centuri IPO in April 2024, and materially ceased following the Final Disposition in September 2025. For more information regarding related party transactions with Southwest Gas Holdings, including the amount of expenses historically allocated, see “Note 17 — Related Parties”.

The Company believes the allocation methodology is reasonable for all periods presented. However, the allocations may not reflect the expenses the Company would have incurred as a standalone public entity for the periods presented. A number of factors, including the chosen organizational structure, division between outsourced and in-house functions and strategic decisions, would impact the actual costs incurred by the Company. The Company has determined that it is not practicable to determine these standalone costs for the periods presented. As a result, the consolidated financial statements are not indicative of the Company’s financial condition, results of operations or cash flows had it operated as a standalone public entity during the periods presented, and results in the consolidated financial statements are not indicative of the Company’s future financial condition, results of operations or cash flows.

Income tax amounts in the consolidated financial statements for fiscal years 2024 and 2023 were calculated using the separate return method and presented as if the Company’s operations were separate taxpayers in their respective jurisdictions, which may or may not have reflected the actual tax filing positions of the Company. Income tax amounts in the consolidated financial statements for fiscal year 2025 include the allocation of certain tax assets as part of income tax deconsolidation from Southwest Gas Holdings, as discussed further in “Income Taxes” below.

Fiscal Period

The Company uses a 52/53-week fiscal year that ends on the Sunday closest to the end of the calendar year. Unless otherwise stated, references to years in the Company’s consolidated financial statements relate to fiscal years rather than calendar years. Unless the context otherwise requires, references to 2025, 2024, and 2023 refer to the fiscal years ended December 28, 2025, December 29, 2024 and December 31, 2023, respectively. Fiscal years 2025, 2024, and 2023 each had 52 weeks.

Principles of Consolidation and Noncontrolling Interests

The accompanying consolidated financial statements reflect the accounts of the Company, all majority-owned subsidiaries and variable interest entities in which the Company or a subsidiary is the primary beneficiary. All intercompany transactions and balances have been eliminated.

The Company is required to perform an analysis each reporting period to determine if it is the primary beneficiary of any company that meets the definition of a variable interest entity (“VIE”). The determination of the primary beneficiary is focused on identifying which enterprise has both the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or receive benefits from the VIE. See “Note 7 — Equity Method Investments” for more information.

The Company also reports a separate component within temporary equity in the consolidated financial statements for the redeemable common stock associated with the minority position related to Riggs Distler & Company, Inc. (“Riggs Distler”), which also represents a noncontrolling interest (“NCI”). The balance of redeemable common stock is reported as the greater of the carrying amount or fair market value.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. The Company reviews all significant estimates affecting its consolidated financial statements on a recurring basis and records the effect of any necessary adjustments in the applicable period. These estimates are based on management’s best knowledge of current events, historical experience, actions that the Company may undertake in the future and various other assumptions that are believed to be reasonable under the circumstance. As a result, actual results could differ from those estimates. Significant estimates in the consolidated financial statements include: useful lives of property and equipment and identifiable intangible assets; the fair value assumptions in analyzing property and equipment, identifiable intangible assets, goodwill, and redeemable noncontrolling interests; allowances for doubtful accounts; revenue recognized under fixed-price contracts; accrued compensation; provision for income taxes; uncertain tax positions; and estimates and assumptions used in the accounting for business combinations.

Revenue Recognition

The Company derives revenue primarily through its diverse array of service solutions to North America’s gas and electric utility providers. Electric power infrastructure services also include storm restoration services, including the repair of infrastructure damaged by inclement weather, and the energized installation, maintenance and upgrade of electric power infrastructure. In addition, the Company performs certain industrial and other construction services for various customers and industries.

The Company generally has two types of agreements with its customers: master services agreements (“MSAs”) and bid contracts.

An MSA identifies most of the terms describing each party’s rights and obligations that will govern future work authorizations. An MSA is often effective for multiple years. A work authorization is issued by the customer to describe the location, timing, unit of work and any additional information necessary to complete the work for the customer. The combination of the MSA and the work authorization determines when a contract exists and revenue recognition may begin. Each work authorization is generally a single performance obligation as the Company is performing a significant integration service. The Company utilizes the portfolio method practical expedient at the customer level as the terms and conditions of MSAs are similar in nature for each customer, but the actual services provided can vary significantly between customers.

A bid contract is typically a one-time agreement for a specific project that has all necessary terms defining each party’s respective rights and obligations. Each bid contract is evaluated for revenue recognition individually. Control of assets created under bid contracts generally passes to the customer over time. Bid contracts often have a single performance obligation as the Company is performing a significant integration service.

For revenue recognition purposes, the Company’s MSAs and bid contracts are characterized as either unit-price, time-and-materials (“T&M”) or fixed-price.

The majority of the Company’s work is performed under unit-price contracts, which generally state prices per unit of installation, or T&M contracts, which are billed as labor hours are incurred, materials are utilized and services are performed. For unit-price and T&M contracts, an output method is used to measure progress towards satisfaction of a performance obligation. Typical installations are accomplished in a few weeks or less, with revenue recorded as units are completed and services are performed. Some unit-price contracts contain caps that, if encroached, trigger revenue and loss recognition similar to a fixed-price contract model.

Performance obligations related to fixed-price contracts are satisfied over time because the Company’s performance typically creates or enhances an asset that the customer controls. The Company recognizes revenue on its fixed-price contracts as performance obligations are satisfied and control of the promised good and/or service is transferred to the customer by measuring the progress toward complete satisfaction of the performance obligation(s) using an input method. The input method results in the recognition of revenue based on the Company’s effort to satisfy the performance obligation relative to the total expected effort to satisfy the performance obligation. The Company uses the cost-to-cost input method to measure progress towards the satisfaction of the performance obligation in fixed-price contracts. Under the cost-to-cost input method, costs incurred to-date are generally the best depiction of transfer of control; therefore, the amount of revenue recognized on fixed-price contracts is based on costs expended to date relative to the anticipated final contract costs.

All contract costs, including those associated with affirmative claims, change orders and back charges, are recorded as incurred and revisions to estimated total costs are reflected as soon as the obligation to perform is determined. Contract costs consist of direct costs on contracts, including labor and materials, amounts payable to subcontractors, direct overhead costs and equipment expense (primarily depreciation, fuel, maintenance and repairs). Most of the Company’s customers supply many of their own materials in order for the Company to complete its work under the contracts.

Actual revenue and project costs can vary, sometimes substantially, from previous estimates due to changes in a variety of factors, including unforeseen circumstances not originally contemplated. These factors, along with other risks inherent in performing fixed-price contracts, may cause actual revenue and gross profit for a project to differ from previous estimates and could result in reduced profitability or losses on projects. Changes in these factors may result in revisions to costs and earnings. Revisions in estimates of costs and earnings during the course of work are reflected in the accounting period in which the facts requiring revision become known. At the time a loss on a contract becomes known or is anticipated, the entire amount of the estimated ultimate loss is recognized in the consolidated financial statements. Once identified, these types of conditions continue to be evaluated for each project throughout the project term, and ongoing revisions in management’s estimates of contract value, contract cost and contract profit are recognized as necessary in the period determined.

Subsequent to the inception of a fixed-price contract, the transaction price could change for various reasons, including the executed or estimated amount of change orders and unresolved contract modifications and claims to or from customers. Changes that are accounted for as an adjustment to existing performance obligations are allocated on the same basis as established at contract inception. Otherwise, changes are accounted for as a separate performance obligation(s) and the separate transaction price is allocated as discussed above.

Contracts can have consideration that is variable. For MSAs, variable consideration is evaluated at the customer level as the terms creating variability in pricing are included within the MSA and are not specific to a work authorization. For multi-year MSAs, variable consideration items are typically determined for each year of the contract and not for the full contract term. For bid contracts, variable consideration is evaluated at the individual contract level. The expected value method or most likely amount method is used based on the nature of the variable consideration. Types of variable consideration include liquidated damages, delay penalties, performance incentives, safety bonuses, payment discounts and volume rebates. The Company will estimate variable consideration and adjust financial information as necessary.

Change orders may involve a modification in scope, price, or both to the current contract, and are typically agreed to in writing by both parties. Once approved, the change order is either treated as a separate contract or as part of the existing contract as appropriate under the circumstances. When the scope is agreed upon in the change order but not the price, the Company estimates the change to the transaction price.

On occasion, the Company recognizes revenue related to contract claims and unapproved change orders. Contract claims and unapproved change orders occur when there is a dispute between the Company and a customer regarding a

change in the scope of work and associated price for work already performed, and/or when the Company otherwise performs work above the scope of the initial contract without a formally executed change order. The Company records estimated claims and unapproved change orders as variable consideration based on the most likely amount it expects to receive, and to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved.

The Company is required to collect taxes imposed by various governmental agencies on the work performed for its customers. These taxes are not included in revenue. Management uses the net classification method to report taxes collected from customers to be remitted to governmental authorities.

Fair Value Measurements

The Company categorizes assets and liabilities, measured at fair value, into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 inputs are quoted prices for identical instruments in active markets. Level 2 inputs are quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs or significant value-drivers are observable. Level 3 inputs are model-derived valuations in which one or more significant inputs or significant value-drivers are unobservable. Fair value measurements are classified according to the lowest level input or value-driver that is significant to the valuation.

The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable, contract assets, book overdrafts, accounts payable, contract liabilities and accrued liabilities approximate fair value because of the short-term nature of these financial instruments.

Cash and Cash Equivalents

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents primarily consist of interest-bearing demand deposits. The Company considers highly liquid investments with original maturities of less than three months, including the Company’s investments in money market funds, to be cash equivalents.

Restricted Cash

Restricted cash consists of cash owned by the Company that is subject to legal restrictions on its use. Restricted cash is classified as either prepaid expenses and other current assets or other assets on the consolidated balance sheets depending on whether the Company expects to use the cash within the next fiscal year.

Accounts Receivable and Allowance for Doubtful Accounts

Amounts due from customers are recorded at face amounts less an allowance for doubtful accounts. The allowance is an estimate based on historical collection experience, current and estimated future economic and market conditions, and a review of the current status of each customer’s trade accounts receivable balance. Account balances are charged against the allowance when management determines it is probable that the receivable will not be recovered.

Accounts receivable, net, includes only amounts that are unconditional in nature, which means only the passage of time remains and the Company has invoiced the customer.

The Company is currently party to an accounts receivable securitization facility whereby it sells accounts receivable to a third-party financial institution. In accordance with ASC 860, “Transfers and Servicing,” the Company derecognizes accounts receivables sold through this facility due to its limited continuing involvement with the accounts receivable after sale. Refer to “Note 6 — Accounts Receivable Securitization Facility” for further details regarding this facility.

Long-Lived Assets

Property and equipment are recorded at cost and include all costs necessary to bring the asset to its intended use. Expenditures for repairs and maintenance are expensed as incurred. Expenditures for major renewals or improvements that extend the useful life of existing equipment are capitalized and depreciated over the remaining useful life of the asset.

Property and equipment include the costs of on-premise software purchased or developed for internal use. Software costs are capitalized when the preliminary project stage is complete and the Company authorizes and commits to funding the project. Software costs cease to be capitalized once all substantial testing is completed. Upgrades and enhancements of internal use software are only capitalized to the extent they will result in additional functionality.

Depreciation is computed using the straight-line method based on the estimated useful lives and salvage values of the related assets. Depreciation expense is recognized as a component of cost of sales or selling and general and administrative expenses within the consolidated statements of operations depending on the nature of the asset being depreciated.

When the Company disposes of property and equipment it recognizes a gain or loss in the statements of operations, which is the result of any proceeds less the net book value of the asset being disposed. The gain or loss on disposition of assets is recognized as a component of cost of revenue or selling, general and administrative expenses within the consolidated statements of operations depending on the nature of the asset being disposed.

Hosting Arrangements

The Company enters into certain cloud-based software hosting arrangements that are accounted for as service contracts (cloud computing arrangements or “CCAs”). The Company may incur and capitalize certain implementation costs to integrate, configure, and customize software as part of these CCAs, which is consistent with the Company’s capitalization of costs incurred during the application development stage for on-premise software. CCA implementation costs are capitalized within other assets within the consolidated balance sheets and expensed on a straight-line basis over the fixed, noncancellable term of the associated hosting arrangements plus any reasonably certain renewal periods.

Long-Lived Asset Impairment

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. When an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset’s carrying amount to determine if an impairment is necessary. Any impairment loss recognized is equal to the amount by which the carrying amount of the asset exceeds its fair value. For fiscal years 2025, 2024, and 2023, the Company did not recognize any significant impairment related to its long-lived assets.

Goodwill

Goodwill represents the excess of cost over the fair market value of net tangible and identifiable intangible assets of acquired businesses and is stated at cost. The Company has recorded goodwill in connection with certain of its business acquisitions. Goodwill is required to be measured for impairment at the reporting unit level, which represents the operating entity level or one level below the operating entity level for which discrete financial information is available.

Goodwill is tested for impairment annually on the first day of the fourth fiscal quarter, or more frequently if events or circumstances arise which indicate that the fair value of a reporting unit with goodwill is below its carrying amount. The Company assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. Qualitative factors assessed for each reporting unit include, among other things, deterioration in macroeconomic conditions; declining financial performance; deterioration in the operational environment; a significant change in market, management, business strategy or business climate; a loss of a significant customer; increased competition; or a decrease in the estimated fair value of a reporting unit.

If the Company believes that, as a result of its qualitative assessment, it is more likely than not that the fair value of a reporting unit is less than its carrying amount, a quantitative impairment test is required. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recorded in the consolidated statements of operations.

Business Combinations

The Company accounts for business combinations using the acquisition method of accounting, which requires that the purchase price, including the fair value of contingent consideration, of the acquired entity to be allocated to the assets acquired and liabilities assumed based generally on the estimated fair values at the date of acquisition. Any excess of the purchase price over the estimated fair value of the identifiable net assets acquired is recorded as goodwill. Acquisition-related expenses and transaction costs associated with business combinations are expensed as incurred.

The determination of the fair value of assets acquired and liabilities assumed requires the Company to make subjective judgments as to projections of future operating performance, discount rates, and long-term growth rates, among other factors, which are typically level 3 inputs. The effect of these judgments then impacts the amount of the goodwill that is recorded and the amount of depreciation and amortization expense to be recognized in future periods related to tangible and intangible assets acquired.

GAAP provides a “measurement period” of up to one year in which to finalize estimates associated with the acquisition of a business. Most estimates are preliminary until the end of the measurement period. During the measurement period, adjustments to initial valuations and estimates that reflect newly discovered information that existed at the acquisition date are recorded as adjustments to the goodwill balance. After the measurement date, any adjustments would be recorded as a current period gain or loss.

Investments in Unconsolidated Affiliates

The Company’s investments in unconsolidated affiliates are investments in entities in which the Company does not have a controlling financial interest, but over which it has significant influence. Investments in unconsolidated affiliates are included in other assets on the consolidated balance sheets. The Company’s share of allocated profit or loss from unconsolidated affiliates is included in other (income) expense, net on the consolidated statements of operations.

The Company’s investment in its unconsolidated affiliate is assessed for other-than-temporary impairment when events or circumstances arise that indicate it is more likely than not that the fair value of the investment is below its carrying value. There were no events or circumstances during 2025, 2024 or 2023 that would indicate an other-than-temporary decline in the value of the Company’s investment in its unconsolidated affiliate existed.

Insurance

The Company utilizes a captive insurance company to insure against the risks associated with workers’ compensation, auto liability and general liability claims. The Company pays administrative fees to certain third-party administrators and consultants and pays claims incurred on a quarterly basis. In connection with these liability insurance policies, the Company is responsible for an initial deductible or self-insured retention amount per occurrence, after which the insurance carriers would be responsible for amounts up to the policy limits. For the policy year spanning May 2025 to April 2026, the Company is responsible for the first $750,000 (deductible) per occurrence under the liability insurance policies. The Company accrues for claims based on projected future losses and associated rates, as calculated by a third-party actuary company.

Leases

The Company determines if an arrangement is a lease at inception. If an arrangement is considered a lease, the Company determines at the commencement date whether the lease is an operating or finance lease. Finance leases are leases that meet any of the following criteria: the lease transfers ownership of the underlying asset at the end of the lease term; the lessee is reasonably certain to exercise an option to purchase the underlying asset; the lease term is for the major

part of the remaining economic life of the underlying asset (except when the commencement date falls at or near the end of such economic life); the present value of the sum of the lease payments and any additional residual value guarantee by the lessee equals or exceeds substantially all of the fair value of the underlying asset; or the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. A lease that does not meet any of these criteria is considered an operating lease. After the commencement date, lease cost for an operating lease is recognized over the remaining lease term on a straight-line basis, while lease cost for a finance lease is based on the depreciation of the lease asset and interest on the lease liability.

A right-of-use (“ROU”) asset represents the Company’s right to use an underlying asset for the lease term, and a ROU lease liability represents the Company’s obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date to determine the present value of lease payments. The Company uses the implicit rate when readily determinable. The operating and finance lease ROU assets also include any lease payments made and excludes lease incentives. The Company’s operating lease terms may include options to extend or terminate the lease when it is reasonably certain the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has elected to account for lease and non-lease components as a single lease component. Leases with an initial term of twelve months or less are classified as short-term leases and are not recognized on the consolidated balance sheets unless the lease contains a purchase option that is reasonably certain to be exercised, or unless it is reasonably certain that the equipment will be leased for greater than twelve months. For sale lease-back transactions, the Company assesses whether control of the underlying asset has transferred to determine whether the transaction qualifies as a sale.

Income Taxes

The Company historically was included on the U.S. federal and certain state income tax returns of Southwest Gas Holdings and calculated income tax amounts using the separate return method as if the Company was a separate taxpayer to allow users to understand the financial position of the Company as a standalone taxable entity. This resulted in the Company recording net deferred tax assets primarily related to net operating losses and interest limitations under Section 163(j) of the Internal Revenue Code of 1986, as amended, which differed from tax attributes actually generated and used by Southwest Gas Holdings as the consolidated and ultimate taxable entity. As discussed in “Note 1 — Description of Business,” Southwest Gas Holdings no longer holds an equity interest in the Company, and accordingly the Company will no longer be included in Southwest Gas Holdings’ U.S. federal and state income tax returns. As a result, certain deferred tax assets previously recorded under the separate return method were removed from the consolidated balance sheet through an adjustment to additional paid-in capital.

In addition, in accordance with the Company’s Tax Assets Agreement (as defined and discussed in “Note 17 — Related Parties”) with Southwest Gas Holdings, the Company was allocated $55.4 million in estimated deferred tax assets (primarily net operating losses) during the fiscal second and third quarters of 2025 as part of income tax deconsolidation. The allocation of these assets was treated as a capital contribution from Southwest Gas Holdings in additional paid-in capital as the Company was still a subsidiary of Southwest Gas Holdings at that time. Adjustments related to the realizability of deferred tax assets contributed from Southwest Gas Holdings upon deconsolidation also impacted additional paid-in capital.

In the fourth quarter of 2025, after the Company had completed income tax deconsolidation and was no longer a subsidiary of Southwest Gas Holdings, a change in Southwest Gas Holdings’ estimate of 2025 taxable income resulted in a $23.7 million increase in deferred tax assets allocable to the Company, recognized as an income tax benefit in the consolidated statement of operations. The allocation of deferred tax assets may continue to change until Southwest Gas Holdings’ 2025 tax returns are filed, with future changes impacting the statement of operations.

The Company has elected to treat its Global Intangible Low-Taxed Income (“GILTI”) as a current period cost when incurred and has considered the estimated GILTI impact in its tax expense. Realization of deferred tax assets is dependent on the Company’s ability to generate sufficient taxable income of an appropriate character in future periods. A valuation allowance is established if it is determined to be more likely than not a deferred tax asset will not be realized. As of December 28, 2025 and December 29, 2024, the Company had not repatriated undistributed earnings from its Canadian subsidiaries. The Company asserts that all future earnings will be permanently reinvested in the Canadian operations. Accordingly, as of December 28, 2025, no U.S. deferred income taxes have been recorded related to cumulative foreign earnings.

In assessing whether uncertain tax positions should be recognized in its financial statements, management determines whether it is more-likely-than-not that a tax position will be sustained upon examination. Interest and penalties related to uncertain income tax positions, if any, are included as a component of income tax expense on the consolidated statements of operations.

Foreign Currency Translation

The Company’s foreign currency-denominated assets and liabilities are translated into U.S. dollars, the Company’s functional currency, at exchange rates existing at the respective balance sheet dates. Translation adjustments resulting from fluctuations in exchange rates are recorded as a separate component of accumulated other comprehensive loss. Results of operations of foreign subsidiaries are translated using monthly weighted average exchange rates during the respective periods. During 2025, 2024, and 2023, the company recorded losses of $0.1 million, $0.1 million and $0.5 million, respectively, related to foreign currency transactions. Gains and losses resulting from foreign currency transactions are included in other income, net on the consolidated statements of operations.

The comparability of the Company’s financial statements has been affected by changes in the value of the Canadian dollar in relation to the U.S. dollar. The financial statement line items most significantly impacted by foreign currency volatility are accounts receivable, contract assets and liabilities, intangible assets, goodwill and long-term debt.

Litigation

From time to time, the Company is subject to ordinary and routine legal proceedings related to the usual conduct of its business. Accruals for such contingencies are recorded to the extent the Company concludes their occurrence is probable and the financial impact of an adverse outcome is reasonably estimable. Legal fees are recognized as incurred and are not included in accruals for contingencies. Specific legal contingencies are disclosed if the likelihood of occurrence is at least reasonably possible, and the exposure is considered material to the consolidated financial statements. In making determinations of likely outcomes of litigation matters, many factors are considered. These factors include, but are not limited to, past history, applicable evidence (and the relative weight thereof), facts and circumstances, the relevant law and the specifics and status of each matter. If the assessment of various factors changes, the estimates may change. Predicting the outcome of claims and litigation and estimating related costs and exposure involves substantial uncertainties that could cause actual costs to vary materially from estimates and accruals. See “Note 18 — Commitments and Contingencies” for more information on current legal proceedings.

Collective Bargaining Agreements

As of December 28, 2025, approximately 57% of the Company’s employees, primarily consisting of craft tradespeople, were covered by collective bargaining agreements. Of the 332 collective bargaining agreements to which the Company is a party, 27 expire during 2026 and 14 expire during 2027 and require renegotiation. The Company’s management and union leadership will determine if there is a need to renegotiate the terms and conditions of these contracts. Although the majority of these agreements prohibit strikes and work stoppages during the term of the agreement, the Company cannot be certain strikes or work stoppages will not occur in the future. Strikes or work stoppages could adversely impact the Company’s relationships with its customers and could have an adverse effect on its business.

Earnings (Loss) Per Share

The Company computes earnings (loss) per share using the treasury stock method. Under the treasury stock method, basic earnings (loss) per share are computed by dividing net income (loss) attributable to common stock by the weighted average number of common shares outstanding during the period, and diluted earnings (loss) per share are computed by dividing net income (loss) attributable to common stock by the weighted average number of common shares outstanding

during the period plus all potentially dilutive common stock equivalents, except in cases where the effect of the common stock equivalent would be anti-dilutive.
