CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements included in this Quarterly Report on Form 10-Q are “forward-looking statements” within the meaning of the U.S. federal securities laws. All statements other than historical factual information are forward-looking statements, including, without limitation, statements regarding our possible or assumed future results of operations, business strategies, financing plans, competitive position, industry environment, potential growth opportunities and the effects of regulation and the economy, generally. Terminology such as “believe,” “anticipate,” “will,” “should,” “could,” “intend,” “plan,” “expect,” “estimate,” “project,” “target,” “may,” “possible,” “potential,” “forecast,” “positioned” and similar references to future periods are intended to identify forward-looking statements, although not all forward-looking statements are accompanied by such words.

Specific forward-looking statements in this Quarterly Report on Form 10-Q include:

•Our belief that our cash and cash equivalents are managed by high credit quality financial institutions;

•Our belief that our capital resources, including existing cash balances, together with our operating cash flows and borrowings under our credit facilities, are sufficient to meet our financial obligations for the next 12 months and the foreseeable future;

•Our belief that the trends listed in “Factors Affecting our Results of Operations” represent a significant challenge for utilities, but also an opportunity for outsourced utility infrastructure services companies to build and maintain more efficient, sustainable infrastructure that can meet the energy needs of future generations;

•Our belief that we have taken steps to secure delivery of a sufficient amount of equipment and do not anticipate any significant disruptions with respect to our fleet in the near-term;

•Our belief that we are well-positioned to serve the increased demand resulting from system integrity management programs to enhance safety pursuant to federal and state mandates;

•Our belief that we are well-positioned to support growing customer attention in achieving environmental objectives through infrastructure construction and maintenance;

•Our belief that we will continue to renegotiate some of our major contracts to address the increased costs of future work;

•Our belief, with respect to our agreements with Southwest Gas Holdings, Inc., that our ongoing obligations are not expected to have a material impact on the Company’s financial condition, results of operations, or cash flows;

•Our belief that any liabilities resulting from any known legal matters, including the City of Chicago matter described in “Note 14 — Commitments and Contingencies — Legal Proceedings,” will not have a material effect on our financial position, results of operations or cash flows;

•Our expectation that we will continue to incur capital expenditures to meet anticipated needs for our services;

•Our belief that the responsibility under a guarantee could exceed the amount recoverable from the subsidiary alone and could materially and adversely affect our consolidated financial condition, results of operations and cash flows;

•Our belief that the timing of the recognition of remaining performance obligations of fixed-price contracts is largely within the control of the customer, including when the necessary equipment and materials required to complete the work will be provided by the customer;

•Our belief that fuel, labor and material costs could rise in the future resulting in a negative effect on our results of operations or that fluctuations in the price or availability of materials and equipment could impact costs to complete projects or result in the postponement of projects;

•Our belief that rising interest rates on our variable-rate debt could have a negative effect on our business, financial condition and results of operations;

•Our belief that projects included in backlog can be subject to delays or cancellation as a result of regulatory requirements, adverse weather conditions, customer requirements and other factors that could cause actual revenue to differ significantly from the estimates, or cause revenue to be realized in periods other than originally expected; and

•Our belief that margins on a new master service agreement are expected to continue to improve throughout the fiscal year.

Notes to Condensed Consolidated Financial Statements

1.Description of Business

Organization Structure

Centuri Holdings, Inc. (“Holdings” and, together with its consolidated subsidiaries, the “Company” or “Centuri”) is a holding company incorporated in Delaware. Substantially all of the Company’s operations are conducted through Centuri Group, Inc. (the “Operating Company”), which is a wholly owned subsidiary of Holdings.

Holdings completed an initial public offering (“IPO”) in April 2024. Following the IPO, the Company’s former parent, Southwest Gas Holdings, Inc. (“Southwest Gas Holdings”), reduced its ownership interest through a series of secondary offerings and private placements which culminated in Southwest Gas Holdings no longer owning any equity interest in the Company effective September 5, 2025. Accordingly, the Company no longer qualifies as a “controlled company” under the New York Stock Exchange rules.

Description of Operations

The Company is a North American utility and energy infrastructure services company, and it partners with regulated utilities to maintain, upgrade, and expand the energy network that powers millions of homes and businesses. The Company’s service offerings primarily consist of the modernization of utility infrastructure through the replacement, maintenance, retrofitting and installation of electric and natural gas distribution and utility-scale transmission networks and building capacity to meet current and future demands. The Company operates through a family of complementary companies working together across different geographies to establish solid customer relationships and a strong reputation for a wide range of capabilities.

In November 2025, the Company completed the acquisition of the equity interests in Connect Atlantic Utility Services Corporation (“Connect”), an Atlantic Canada electric utility services provider. Connect’s results are included in the Canadian Operations segment. Connect’s revenue during the first fiscal quarter of 2026 was approximately $23.2 million, and Connect’s earnings were not material. The Company did not record any measurement period adjustments during the first fiscal quarter of 2026. Due to the estimations made, the final purchase accounting has not yet been completed and further refinements may occur.

2.Basis of Presentation and Recent Accounting Pronouncements

Interim Condensed Consolidated Financial Information

The unaudited condensed consolidated financial statements and footnotes were prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete annual financial statements. Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with GAAP, have been condensed or omitted pursuant to those rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto as included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 28, 2025. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations, comprehensive loss and cash flows with respect to the interim condensed consolidated financial statements have been included. The results of operations and comprehensive loss for the interim periods are not necessarily indicative of the results for the entire fiscal year. The results of the Company have historically been subject to significant seasonal fluctuations.

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 months, quarters and years in the Company’s condensed consolidated financial statements relate to fiscal months, quarters and years rather than calendar months, quarters and years. The first fiscal quarters of 2026 and 2025 ended on March 29, 2026 and March 30, 2025, respectively, and each period had 13 weeks.

Table of Contents

Recent Accounting Pronouncements

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.

3.Revenue and Related Balance Sheet Accounts

The following table presents the Company’s revenue from contracts with customers disaggregated by contract type (in thousands):


	Fiscal Three Months Ended
	March 29, 2026		March 30, 2025
Contract Type:
Master services agreements	$	534,060	$	419,249
Bid contracts	189,114		130,832
Total revenue	$	723,174	$	550,081

Unit-price contracts	$	379,041	$	285,228
Time and materials contracts	193,399		135,040
Fixed-price contracts	150,734		129,813
Total revenue	$	723,174	$	550,081

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


	March 29, 2026		December 28, 2025
Current contract assets	$	347,823	$	395,126
Non-current contract assets	35,113		30,927
Contract assets, total	382,936		426,053
Contract liabilities	(58,428)		(50,510)
Net contract assets	$	324,508	$	375,543

Contract assets primarily consist of revenue recognized on contracts in progress in excess of billings, which relates to the Company’s rights to consideration for work completed but not yet billed and/or approved at the reporting date, including retention amounts. Revenue earned on contracts in progress in excess of billings are transferred to accounts receivable when the rights become unconditional. Contract assets that are not expected to be billed and collected within one year of the financial statement date (“Non-current contract assets”) are classified as other assets on the condensed consolidated balance sheets. The Company applies the same approach to accounts receivable it does not expect to collect within one year.

Current contract assets included retention balances of approximately $39.5 million and $40.6 million as of March 29, 2026 and December 28, 2025, respectively, which are typically billed and collected upon project completion.

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 customer approval. As of March 29, 2026 and December 28, 2025, the Company had recorded approximately $53.8 million ($22.0 million non-current in other assets) and $47.8 million ($19.7 million non-current in other assets), respectively, in contract assets related to contract claims and unapproved change orders.

Total contract assets decreased $43.1 million during the fiscal three months ended March 29, 2026 as the completion of milestones and customer approvals allowed for billing of amounts included in contract assets as of December 28, 2025.

Contract assets are recoverable from the Company’s customers based upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract. In addition, many of

Table of Contents

the Company’s time and materials (“T&M”) contract arrangements are billed in arrears pursuant to contract terms that are standard within the industry, resulting in revenue earned on contracts in progress in excess of billings and/or unbilled receivables being recorded as revenue is recognized in advance of billings. The lag in billing due to the aforementioned contractual provisions may create circumstances in which material changes to a customer’s business, cash flows or financial condition, which may be impacted by negative economic or market conditions, could affect the Company’s ability to bill and subsequently collect amounts due. These changes may result in the need to record an estimate of the amount of loss from uncollectible receivables.

Contract liabilities primarily consist of amounts billed in excess of revenue earned related to the advance consideration received from customers for which work has not yet been completed. The increase in the contract liabilities balance of $7.9 million from December 28, 2025 to March 29, 2026 was due to additional payments received in advance of work completed, net of approximately $30.9 million of revenue recognized that was included in the balance as of December 28, 2025.

The Company considers retention and unbilled amounts to customers to be conditional contract assets, as payment is contingent on the occurrence of a future event. 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. Similarly, contract liabilities include amounts billed in excess of revenue earned on contracts in progress related to fixed-price, unit-price and T&M contracts.

For contracts where payment is expected to be collected less than one year from when services are performed (as determined at contract inception), the Company uses the practical expedient and does not consider the time value of money. For contracts with an original duration of one year or less, the Company has not disclosed the transaction price for the remaining performance obligations as of the end of each reporting period or the related timing of revenue recognition.

As of March 29, 2026, the Company had 62 fixed-price contracts with an original duration of more than one year. The aggregate amount of the transaction price allocated to the unsatisfied performance obligations of these contracts as of March 29, 2026 was $444.7 million. The Company expects to recognize substantially all of these remaining performance obligations of these contracts over approximately the next two years; however, the timing of that recognition is largely within the control of the customer, including when the necessary equipment and materials required to complete the work will be provided by the customer.

Accounts receivable, net consisted of the following (in thousands):


	March 29, 2026		December 28, 2025
Billed on completed contracts and contracts in progress	$	351,691	$	312,003
Other receivables	2,318		2,699
Accounts receivable, gross	354,009		314,702
Allowance for doubtful accounts	(955)		(37)
Accounts receivable, net	$	353,054	$	314,665

4.Segment Information

The Company’s reportable segments are: (i) U.S. Gas Utility Services (“U.S. Gas”); (ii) Canadian Utility Services (“Canadian Operations”); (iii) Union Electric Utility Services (“Union Electric”); and (iv) Non-Union Electric Utility Services (“Non-Union Electric”). Canadian Operations includes the results of Connect, which was acquired in November 2025.

The Company’s president and chief executive officer serves as the Company's chief operating decision maker (the "CODM"). The Company’s reportable segments are established in consideration of differences in services, geographic areas and workforce composition (union vs. non-union). The Company has not aggregated any operating segments into reportable segments. The CODM reviews short-term and long-term trends and budget-to-actual variances in gross profit to assess performance across the different segments in determining where to allocate resources.

U.S. Gas

U.S. Gas provides comprehensive services, including maintenance, replacement, repair, and installation for local natural gas distribution utilities (“LDCs”) focused on the modernization of customers’ infrastructure throughout the United

Table of Contents

States. The work performed within this segment includes solutions for all stages of utility work and is performed primarily within the distribution, utility-scale transmission and end-user infrastructure, rather than large-scale, project-based, cross-country transmission. In addition, U.S. Gas performs other underground services, including water and fiber, and has an in-house fabrication shop providing pipe and component assembly. The Company is able to cater to the needs of its gas utility services and energy customers by serving union and non-union markets.

Canadian Operations

Canadian Operations provides comprehensive services, including maintenance, replacement, repair, and installation for local gas and electric utilities and energy providers. A majority of the work performed in this segment is focused on distribution, urban transmission and end-user interface under master service agreements (“MSAs”) for gas and electric utilities. This segment also provides storm response services and performs construction of electrical systems used in renewable energy projects.

Union Electric

Union Electric provides a comprehensive set of electric utility services encompassing maintenance, replacement, repair, storm response, upgrade and expansion services for urban transmission and local distribution infrastructure within union markets. The work performed within this segment is focused primarily on recurring local distribution and urban transmission services under MSAs, as opposed to large-scale, project-based, cross-country transmission, and services are primarily focused on infrastructure between the substation and end-user meter. In addition to core electric utility infrastructure, this segment provides heavy industrial work, including civil, mechanical, electrical, and fabrication (component assembly) services.

Non-Union Electric

Non-Union Electric provides a comprehensive set of electric utility services encompassing maintenance, replacement, repair, storm response, upgrade and expansion services for urban transmission and local distribution infrastructure within non-union markets. The work performed within this segment is focused almost exclusively on recurring local distribution and urban transmission services under MSAs as opposed to large-scale, project-based, cross-country transmission, and services are primarily focused on infrastructure between the substation and end-user meter.

There were no dilutive securities for any periods presented due to the Company recording a net loss, and therefore the denominator for basic and diluted loss per share was the same for all periods. Potentially dilutive shares that would have been dilutive if the Company had recorded net income were not material for the fiscal three months ended March 29, 2026 or March 30, 2025.

6.Accounts Receivable Securitization Facility

In September 2024, the Company entered into a three-year accounts receivable securitization facility for an aggregate amount of up to $125.0 million (the “Securitization Facility”), with PNC Bank, National Association (“PNC"), to enhance the Company's financial flexibility by providing additional liquidity.

Under the Securitization Facility, certain designated subsidiaries of the Company may sell or contribute their accounts receivable and contract assets generated in the ordinary course of their businesses and certain related assets to an indirect wholly owned bankruptcy-remote Special Purpose Entity (“SPE”) of the Company created specifically for this purpose. The SPE is a variable interest entity, and the Company is the primary beneficiary and therefore consolidates the SPE. The SPE transfers ownership and control of accounts receivable to PNC for payments as set forth in the agreement. The Company accounts for accounts receivable sold to the banking counterparty as a sale of financial assets and has derecognized the accounts receivable from the condensed consolidated balance sheet for the current period.

The total outstanding balance of accounts receivable that had been sold and derecognized was $125.0 million as of March 29, 2026. The Company had no unused capacity on the Securitization Facility as of both March 29, 2026 and December 28, 2025.

As of March 29, 2026, the SPE owned $39.6 million in accounts receivable and $116.8 million in contract assets that were not sold to PNC. As of December 28, 2025, the corresponding amounts were $60.2 million and $115.6 million. These balances are primarily included in accounts receivable, net and contract assets in the Company’s condensed consolidated balance sheet, with certain non-current balances included in other assets.

During the fiscal three-month periods ended March 29, 2026 and March 30, 2025, the Company incurred $1.6 million and $1.8 million, respectively, in yield fees on the Securitization Facility, which were recorded in interest expense, net on the Company’s condensed consolidated statements of operations.

On May 4, 2026, the Company signed an amendment to the Securitization Facility which increased the capacity from $125.0 million to $165.0 million.

On August 27, 2021, the Company entered into an amended and restated credit agreement. The agreement provided for a $1.145 billion secured term loan facility, at a discount of 1.00%, and a $400 million secured revolving credit facility. On July 9, 2025, the Company signed the sixth amendment to its amended and restated credit agreement to refinance and replace in full the existing term loan facility with an $800 million term loan facility, $93.6 million of which was comprised of new term loans used to refinance existing indebtedness and $706.4 million of which was used to refinance existing term loans. This amendment also increased the maximum principal amount of the senior secured revolving credit facility from $400 million to $450 million. This multi-currency facility allows the Company to request loan advances in either Canadian dollars or U.S. dollars. Amounts borrowed and repaid under the revolving line of credit portion of the facility are available

Table of Contents

to be re-borrowed. The Company’s term loan facility is set to mature on July 9, 2032, and the revolving credit facility is set to mature on July 9, 2030.

The obligations under the credit agreement are secured by present and future ownership interests in substantially all direct and indirect subsidiaries of the Company, substantially all of the tangible and intangible personal property of each borrower, and all products, profits, and proceeds of the foregoing. The Company’s assets securing the facility as of March 29, 2026 totaled $2.3 billion. The credit agreement also contains a restriction on dividend payments with an available amount generally defined as $65.0 million plus 50% of the Company’s consolidated net income since the beginning of the third fiscal quarter of 2025 adjusted for certain items, such as parent capital contributions, redeemable noncontrolling interest payments, and dividend payments, among other adjustments, as applicable.

The applicable margin for the revolving credit facility ranges from 1.25% to 2.25% for SOFR and Canadian Overnight Repo Rate Average (“CORRA”) loans and from 0.25% to 1.25% for base rate loans, depending on the Company’s net leverage ratio. The term loan facility has a fixed margin of 1.00% for base rate loans and 2.00% for SOFR loans. The table below summarizes the weighted average interest rates on the term loan facility and revolving credit facility as of the end of March 29, 2026 and December 28, 2025:


	March 29, 2026		December 28, 2025
Term loan facility	5.67	%	6.12	%
Revolving credit facility	3.82	%	4.54	%

The Company is required to maintain a leverage ratio of 4.50 to 1.00 for any future quarter ending prior to September 30, 2026, and 4.00 to 1.00 for any quarter ending on or after September 30, 2026. The Company is also required to maintain an interest coverage ratio of greater than a minimum of 2.50 to 1.00.

As of March 29, 2026, the Company was in compliance with all of the financial covenants under the revolving credit facility. The Company is required to pay a commitment fee on the unused portion of the commitments which ranges from 0.15% to 0.35% per annum, depending on the Company’s net leverage ratio.

As of both March 29, 2026 and December 28, 2025, the Company had borrowings outstanding of $0.7 billion under its amended and restated credit agreement. The amount available under the revolving line of credit is further reduced by the amount of any outstanding letters of credit issued by the Company under the agreement. Accordingly, there was $303.9 million, net of outstanding letters of credit, of unused capacity on the revolving line of credit as of March 29, 2026. The Company had $68.6 million of unused letters of credit available as of both March 29, 2026 and December 28, 2025. Debt issuance costs associated with the Company’s line of credit are amortized over the term of the related line of credit. As of March 29, 2026 and December 28, 2025, there was $2.7 million and $2.9 million, respectively, in debt issuance costs recorded in other assets on the condensed consolidated balance sheets.

As of March 29, 2026, the Company had $32.6 million of surety-backed letters of credit issued outside of its amended and restated credit agreement.

Debt issuance costs associated with the Company’s term loan facility are amortized over the term of the related debt, which approximates the effective interest method. As of March 29, 2026 and December 28, 2025, debt issuance costs of $10.4 million and $10.8 million, respectively, were recorded as a reduction to long-term debt on the condensed consolidated balance sheets.

Amortization expense related to debt issuance costs is recorded as a component of interest expense in the condensed consolidated statements of operations. During the fiscal three months ended March 29, 2026 and March 30, 2025, amortization of debt issuance costs was $0.6 million and $1.2 million, respectively.

As of March 29, 2026, the Company had six U.S. equipment term loans with initial amounts totaling approximately $150.0 million, with certain owned equipment used as collateral. The loans are serviced in U.S. dollars.

The fair value of the Company’s debt as of both March 29, 2026 and December 28, 2025 was $0.7 billion. The carrying value of the Company’s revolving credit facility approximates fair value given interest rates on the revolving credit facility approximate market rates, and typically draws on the revolving credit facility are paid back in a short period of time. The fair values of the Company’s term loan facility and equipment loans were determined utilizing a market-based

valuation approach, where fair values are determined based on evaluated pricing data, and as such are categorized as Level 2 in the hierarchy.

10.Leases

The Company has operating and finance leases for corporate and field offices, equipment yards, construction equipment and transportation vehicles. The Company is currently not a lessor in any significant lease arrangements. The Company’s leases have remaining lease terms of up to 12 years. Some of these leases include options to extend the leases, generally for optional terms of up to five years, and some include options to terminate the leases within one year. The equipment leases may include variable payment terms in addition to the fixed lease payments if machinery is used in excess of the standard work periods. The occurrence of these variable payments is not probable under the Company’s current operating environment and has not been included in consideration of lease payments. Leases with an initial term of 12 months or less are classified as short-term leases and are not recognized on the condensed 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 or property will be leased for greater than 12 months. Due to the seasonality of the Company’s operations, expense for short-term leases will fluctuate throughout the year with higher expense typically incurred during the periods when revenue is the greatest. As of March 29, 2026, the Company did not have any significant executed lease agreements that had not yet commenced.

The components of lease expense were as follows (in thousands):

Certain leases require the Company to pay variable property taxes, insurance and maintenance costs that have been excluded from the minimum lease payments in the above tables as they are variable in nature.

11.Income Taxes

The Company’s current quarter provision for income taxes was prepared using the annual effective tax rate adjusted to remove discrete items, as those items will impact the quarter in which those items were reflected. The Company’s effective tax rate for the fiscal three-month periods ended March 29, 2026 and March 30, 2025 was 45.0% and 42.3%, respectively. Effective tax rates for both periods were impacted by the disproportionate amount of non-deductible expenses in relation to loss before income taxes. Additionally, differences in income (loss) before income taxes by jurisdiction caused fluctuations in the effective tax rate when comparing periods.

The Company regularly evaluates valuation allowances established for deferred tax assets for which future realization is uncertain, including in connection with changes in tax laws. The Company maintains a valuation allowance on certain state net operating loss carryforwards and for Canadian capital losses. Such valuation allowances are released as the related tax benefits are realized or when sufficient evidence exists to conclude that it is more likely than not the deferred tax assets will be realized.

There were no unrecognized tax benefits recorded relating to uncertain tax positions as of March 29, 2026 or December 28, 2025.

As of March 29, 2026, with certain exceptions, the Company is no longer subject to U.S. federal, state, local, or Canadian examinations for years before fiscal year 2019.

Agreements related to the Separation from Southwest Gas Holdings

In connection with the Company’s IPO and separation from Southwest Gas Holdings, Holdings previously entered into a Separation Agreement, Tax Matters Agreement, and Registration Rights Agreement with Southwest Gas Holdings. Following Southwest Gas Holdings’ disposition of its remaining ownership interest in Centuri on September 5, 2025, many provisions of these agreements, including Southwest Gas Holdings’ governance rights and registration rights, have terminated or are no longer applicable.

The remaining provisions primarily relate to customary indemnification and cooperation obligations. As of the date of this report, there are no known claims, proceedings, or contingencies that would require indemnification by or to the

Table of Contents

Company under these agreements, and the ongoing obligations are not expected to have a material impact on the Company’s financial condition, results of operations, or cash flows.

On February 24, 2025, the Company entered into an Unutilized Tax Assets Settlement Agreement (the “Tax Assets Agreement”) with Southwest Gas Holdings, which governs the treatment of certain unutilized tax assets (the “Tax Assets”) retained by the Company following its deconsolidation from Southwest Gas Holdings for purposes of U.S. federal and relevant state income tax laws. Under the terms of the Tax Assets Agreement, such Tax Assets were initially treated as deemed capital contributions and recorded within additional paid‑in capital. After Southwest Gas Holdings’ ownership of the Company decreased below 50%, subsequent adjustments to Tax Assets were reflected as an adjustment to income tax benefit in the Company’s condensed consolidated statements of operations.

Tax Assets allocated to the Company remain subject to true‑up until after Southwest Gas Holdings files its U.S. federal and applicable state income tax returns for tax year 2025. Any future changes resulting from the true‑up process will be reflected in the Company’s condensed consolidated statements of operations. There were no changes during the first fiscal quarter of 2026.

Riggs Distler noncontrolling interest

In November 2021, certain members of management of Riggs Distler, a subsidiary of the Company, acquired a 1.42% interest in the parent company of Riggs Distler, Drum Parent LLC (“Drum”). The remaining noncontrolling interest in Drum outstanding as of March 29, 2026 was 0.80%.

14.Commitments and Contingencies

Legal Proceedings

The Company is a named party in various legal proceedings arising from the normal course of business. Although the ultimate outcomes of active matters are currently unknown, the Company does not believe any liabilities resulting from these known matters will have a material effect on its financial position, results of operations or cash flows, unless otherwise stated below.

NPL Construction Co. (“NPL”), a subsidiary of the Operating Company, is currently pursuing a contract claim for damages against the City of Chicago and related parties (collectively, the “City”), arising out of work that NPL performed for the City. NPL initiated this dispute through the City’s required administrative process on August 26, 2019. In response to NPL’s claim, the City has taken the position that it is entitled to withhold payments on amounts NPL believes it is owed for work already completed, claiming that further corrective work by NPL on the project is necessary and that withholding payment is appropriate until remediation is complete. On July 18, 2024, the administrative agency issued a decision denying NPL’s claim for damages. The Company disagrees with the decision of the administrative agency, and NPL filed a petition seeking a review of the administrative agency’s decision by the Circuit Court of Cook County Illinois on November 8, 2024. On April 20, 2026, the Circuit Court entered an interlocutory memorandum opinion and order addressing some, but not all, of NPL’s claims, with the remaining claims requiring later briefing and argument. The Company intends to vigorously pursue this matter, including undertaking further legal analysis of the Circuit Court’s recent interlocutory memorandum opinion and order; however, the Company cannot accurately predict the ultimate outcome. The Company may be entitled to additional revenue if all of its claims for relief are awarded in the Company’s favor. However, to the extent the Company is not successful in collecting the withheld receivables, this matter could result in an additional significant loss, which is not currently estimable due to uncertainties with respect to the proceedings. The Company can provide no assurance as to whether or when there will be material developments in this matter. The Company has not accrued any reserves for this matter to date.

The Company maintains liability insurance for various risks associated with its operations. In connection with its 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.

Employment Agreements

The Company has employment agreements with certain executives and other employees, which provide for compensation and certain other benefits and for severance payments under certain circumstances. Certain employment agreements also contain severance clauses that become effective upon a change in control of the Company. Upon the

Table of Contents

occurrence of certain defined events in the various employment agreements, the Company would be obligated to pay varying amounts to the related employees, which vary with the level of the employees’ respective responsibilities.

Concentration of Credit Risk

The Company provides full-service utility infrastructure services to various customers, primarily utility companies that are located throughout the U.S. and Canada. The Company is subject to concentrations of credit risk related primarily to its revenue and accounts receivable and contract asset positions with customers, which is defined as greater than or equal to 10% of the Company’s consolidated balances. During the fiscal three months ended March 29, 2026 and March 30, 2025, one Non-Union Electric segment customer accounted for more than 10% of revenue, which was $94.5 million (13% of total revenue) and $56.1 million (10% of total revenue), respectively. As of March 29, 2026 and December 28, 2025, one Non-Union Electric segment customer had a combined accounts receivable and contract assets balance above 10% of the consolidated accounts receivable and contract assets balance, which was $163.2 million and $131.9 million, respectively, or approximately 23% and 19%, respectively, of the consolidated balance of these accounts.

The Company primarily uses two financial banking institutions. The Company’s cash on deposit with these financial institutions exceeded the federal insurability limits as of March 29, 2026. The Company believes its cash and cash equivalents are managed by high credit quality financial institutions.

Bonds and Parent Guarantees

Many customers, particularly in connection with new construction, require the Company to post performance and payment bonds. These bonds provide a guarantee that the Company will perform under the terms of a contract and pay its subcontractors and vendors. In certain circumstances, the customer may demand that the surety make payments under the bond, and the Company must reimburse the surety for any expenses or outlays it incurs. The Company may also be required to post letters of credit as collateral in favor of the sureties, which would reduce the borrowing availability under its revolving credit facility. As of March 29, 2026, the Company was not aware of any outstanding material obligations for payments related to these bond obligations.

Performance bonds expire at various times ranging from mechanical completion of a project to a period extending beyond contract completion in certain circumstances, and therefore a determination of maximum potential amounts outstanding requires certain estimates and assumptions. Such amounts can also fluctuate from period to period based upon the mix and level of the Company’s bonded operating activity. As of March 29, 2026, the estimated total amount of outstanding performance and payment bonds was approximately $820.3 million. The Company’s estimated maximum exposure related to the value of the performance bonds outstanding is lowered on each bonded project as the cost to complete is reduced, and each commitment under a performance bond generally extinguishes concurrently with the expiration of its related contractual obligation. The estimated cost to complete these bonded projects was approximately $351.7 million as of March 29, 2026.

Additionally, from time to time, the Company guarantees certain obligations and liabilities of its subsidiaries that may arise in connection with, among other things, contracts with customers, and equipment and real estate lease obligations. These guarantees may cover all of the subsidiary’s unperformed, undischarged and unreleased obligations and liabilities under or in connection with the relevant agreement. The Company is not aware of any claims under any guarantees that are material. The responsibility under a guarantee could exceed the amount recoverable from the subsidiary alone and could materially and adversely affect the Company’s consolidated financial condition, results of operations and cash flows.

15.Stock-based Compensation

The Company maintains a stock-based compensation plan, which authorizes the granting of various equity-based incentives, including restricted stock units (“RSUs”) and performance stock units (“PSUs”). Stock-based compensation expense is amortized on a straight line basis over the service period, which is generally the vesting period. The fair value of the Company’s RSU and PSU awards is measured at the market price of the Company’s common stock on the grant date. PSUs are earned based on the achievement of certain performance metrics in relation to a set target, and stock compensation expense may fluctuate based on the forecasted achievement prior to vesting or actual achievement of these target metrics upon vesting.

RSU grants to employees generally vest ratably on an annual basis over a three-year period following the grant date, although some awards may vest ratably on an annual basis over two years or cliff vest at the end of a shorter time period.

Table of Contents

RSU grants to non-employee directors typically vest at the end of a one-year period. PSU grants generally cliff vest at the end of a three-year period following the grant date. Forfeitures are recorded as they occur.

Stock-based compensation expense totaled approximately $2.2 million and $1.6 million for the fiscal three-month periods ended March 29, 2026 and March 30, 2025, respectively.

The table below summarizes activity related to the Company’s stock-based compensation plans during the first fiscal quarters of 2025 and 2026.

(1)PSUs granted under the Company’s 2025 Omnibus Incentive Plan were initially measured assuming target achievement of the applicable performance goals. One‑third of the total units were eligible to be earned based on performance for the fiscal year ended December 28, 2025. Following certification of performance results for this one-year period, earned units were converted into RSUs based on the level of achievement (105.1% of target) certified, as only the passage of time remains.

As of March 29, 2026, total unearned compensation related to Centuri stock RSUs and PSUs was approximately $11.6 million and $9.6 million, respectively. These amounts are expected to be recognized over a weighted average period of approximately 1.5 years and 2.3 years, respectively.

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

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and corresponding notes in Item 1 — Financial Statements within Part I of this Quarterly Report on Form 10-Q, and our Annual Report on Form 10-K for the fiscal year ended December 28, 2025 filed with the SEC on February 26, 2026 (our “2025 Annual Report”).

Unless the context otherwise requires, references to “we,” “us,” “our,” “the Company,” and “our Company” refer to Centuri Holdings, Inc. and its consolidated subsidiaries. This discussion contains forward-looking statements that are based upon current expectations and are subject to uncertainty and changes in circumstances. Our actual results could differ materially from the results contemplated by these forward-looking statements due to a number of factors, including those discussed within Item 1A. Risk Factors in our 2025 Annual Report. See “Cautionary Note Regarding Forward-Looking Statements.”

We use a 52/53-week fiscal year that ends on the Sunday closest to the end of the calendar year. Unless otherwise stated, references to months and quarters throughout relate to fiscal months and quarters rather than calendar months and quarters. The first fiscal quarters of 2026 and 2025 ended on March 29, 2026 and March 30, 2025, respectively, and each period had 13 weeks.

Overview

Company Overview

We are a leading North American utility and energy infrastructure services company, and we partner with regulated utilities to maintain, upgrade and expand the energy network that powers millions of homes and businesses. We serve as a long-term strategic partner to, and an extension of, North America’s electric, gas and combination utility providers, delivering a wide range of infrastructure solutions to ensure safe, reliable and environmentally sustainable energy operations. Our service offerings primarily consist of the modernization of utility infrastructure through the replacement, maintenance, retrofitting and installation of electric and natural gas distribution and utility-scale transmission networks and building capacity to meet current and future demands. We also serve complementary, attractive and growing end markets such as distributed power projects and data centers. Our essential services enable our customers to enhance the safety, reliability and environmental sustainability of the electric and natural gas networks that consumers rely upon to meet their essential and evolving energy needs. Our strategy is focused primarily on maintaining and growing services to our existing customers through master service agreements (“MSAs”) and bid work, securing new customer relationships, providing services to select adjacent end-markets, expanding our geographic footprint further into the Southeastern and Midwestern United States and Canada, and diversifying our portfolio of work. Guided by our values and our unwavering commitment to serve as a long-term partner to customers and communities, our employees enable our customers to safely and reliably deliver electricity and natural gas and achieve their goals for environmental sustainability.

Separation from Southwest Gas Holdings

We completed an initial public offering (“IPO”) in April 2024. Following the IPO, our former parent, Southwest Gas Holdings, Inc. (“Southwest Gas Holdings”), reduced its ownership interest through a series of secondary offerings and private placements which culminated in Southwest Gas Holdings no longer owning any equity interest in our Company effective September 5, 2025. Accordingly, we no longer qualify as a “controlled company” under the New York Stock Exchange rules.

Segment Information

We report under the following four reportable segments: (i) U.S. Gas Utility Services (“U.S. Gas”); (ii) Canadian Utility Services (“Canadian Operations”); (iii) Union Electric Utility Services (“Union Electric”); and (iv) Non-Union Electric Utility Services (“Non-Union Electric”). Canadian Operations includes the results of Connect Atlantic Utility Services Corporation (“Connect”), which was acquired in November 2025.

Factors Affecting Our Results of Operations

Our financial results may be impacted by economic conditions that impact businesses generally, such as inflationary impacts on goods and services consumed in the business, regulatory or environmental influences, seasonality and severe

Table of Contents

weather events, rising interest rates, labor markets and costs (including in regard to contracted or professional services), and the availability of those resources. Accordingly, our operating results in any particular period may not be indicative of the results that can be expected for any other period.

Market Developments

North America relies on electric and natural gas delivery infrastructure to maintain its dynamic economy, but existing infrastructure is subject to degradation and is often decades old. Governments have increased regulatory stringency and enacted legislation to support the necessary infrastructure investments in the sector, aimed at preventing disruption, enhancing safety and readying to meet current and future demands. Additionally, labor market constraints and a changing utility workforce have led utilities to become increasingly reliant on external outsourced utility infrastructure service providers, creating an overall growing market well-positioned for consolidation. We believe these trends represent a significant challenge for utilities, but also an opportunity for outsourced utility infrastructure services companies to build and maintain more efficient, sustainable infrastructure that can meet the energy needs of future generations.

Rising fuel, labor and material costs have in the past had, and could in the future have, a negative effect on our results of operations, to the extent we cannot pass these costs through to our customers. While we actively monitor economic, industry and market factors that could adversely impact our business, we cannot predict the effect that changes in such factors could have on our future results of operations, financial position and cash flows. Our results of operations in the first fiscal quarter of 2026 were not materially impacted by market developments, including elevated fuel costs. We are continuing to monitor the impacts of elevated fuel costs, but we do not expect a material impact on our results of operations at this time.

Generally, our contracts provide that the customer is responsible for supplying the materials for their projects. Fluctuations in the price or availability of materials and equipment that we or our customers utilize could impact (positively or negatively, as applicable) costs to complete projects or result in the postponement of projects. Although certain of our customers have experienced previous disruptions in their supply chain for certain project materials, most of our customers have generally been able to procure the necessary materials in a timely manner.

Our operations also depend on the availability of certain equipment to perform services. We believe we have taken steps to secure delivery of a sufficient amount of equipment and do not anticipate any significant disruptions with respect to our fleet in the near-term.

Demand for Services

The seasonal nature of the industry we serve affects demand for our services. In addition to weather conditions, capital expenditure and maintenance budgets of our customers, as well as the related timing of approvals and seasonal spending patterns, influence our contract revenue and results of operations. Factors affecting our customers and their capital expenditure budgets include, but are not limited to, overall economic conditions, the introduction of new technologies, and our customers’ capital resources, financial performance, and strategic plans. Other factors that may impact our customers and their capital expenditure budgets include new regulations or regulatory actions, merger or acquisition activity involving our customers and the physical maintenance needs of our customers’ infrastructure.

Fluctuations in market prices for oil, gas and other energy sources can impact demand for our services. Such fluctuations can affect the level of activity in energy generation projects as well as pipeline construction projects. The availability of transportation and transmission capacity can also impact demand for our services, including energy generation, electric grid and pipeline construction projects. These fluctuations, as well as the highly competitive nature of our industry, can result in changes in the levels of activity, project mix and moreover the profitability of the services we provide.

Utilities continue to implement or modify system integrity management programs to enhance safety pursuant to federal and state mandates. These programs have resulted in multi-year utility system replacement programs throughout the U.S., and we believe that we are well-positioned to serve the increased demand resulting from these programs.

Our services support customers’ environmental goals, such as reducing methane emissions from pipeline leaks through pipe repair and replacement, hardening electric infrastructure to prevent damage from storms or otherwise, and assisting gas and electric customers with their renewable and sustainable energy infrastructure initiatives. We believe that we are

Table of Contents

well-positioned to support growing customer attention in achieving environmental objectives through infrastructure construction and maintenance.

Project Variability

Margins for our projects may vary from period to period due to changes in the volume or type of work performed and the pricing structure of our projects. Additionally, factors such as site conditions, project location, labor shortages, weather events, environmental restrictions, regulatory delays, protests, political activity, legal challenges, or the performance of third parties may adversely impact our project performance.

In certain circumstances, such as with large bid contracts (especially those of a longer duration), or unit-price contracts with revenue caps, results may be impacted by differences between costs incurred and those anticipated when the work was originally bid. Work awarded, or failing to be awarded, by individual large customers can impact our results of operations.

Seasonality and Severe Weather Events

Generally, our revenue is lowest during the first fiscal quarter of the year due to less favorable winter weather and related working conditions in many of the areas where we perform work. Revenue typically improves as more favorable weather conditions occur during the summer and fall months. In cases of severe weather, such as following a regional storm, we may be engaged to perform restoration activities related to above-ground utility infrastructure, which typically results in higher margins due to higher equipment utilization and the absorption of fixed costs. Alternatively, these severe weather events can also delay projects, negatively impacting our results of operations. Severe weather events and the related impacts on our performance and results are not solely within the control of management and cannot always be predicted or mitigated.

Inflation

Under the terms of a majority of our MSAs and other customer agreements, materials used in our utility infrastructure service activities are specified, purchased and supplied by customers. However, our operations are affected by increases in prices, whether caused by inflation, tariffs, rising interest rates or other economic factors. We attempt to recover anticipated increases in the cost of labor, equipment, fuel and materials not purchased by customers through price escalation provisions that allow us to adjust billing rates for certain major contracts annually; by considering the estimated effect of such increases when bidding or pricing new work; or by entering into back-to-back contracts with suppliers and subcontractors. However, the annual adjustment provided by certain contracts is typically subject to a cap and there can be an extended period of time between the impact of inflation on our costs and when billing rates are adjusted. Our actual costs at times can exceed the contractual caps, and therefore negatively impact our operations. Additionally, rising interest rates on our variable-rate debt could have a negative effect on our business, financial condition and results of operations. Overall, our results for the first fiscal quarter of 2026 were not significantly impacted by increases in prices, including due to tariffs implemented by the Trump Administration.

Backlog

Backlog as of March 29, 2026 was approximately $6.5 billion, with approximately 85% of backlog related to MSAs. Backlog represents contracted revenue on existing bid agreements as well as estimates of revenue to be realized over the contractual life of existing long-term MSAs. The contractual life of an MSA is defined as the stated length of the contract including any renewal options stated in the contract that we believe our customers are reasonably certain to execute.

Backlog differs from remaining performance obligations disclosed in “Note 3 — Revenue and Related Balance Sheet Accounts” to the condensed consolidated financial statements, as remaining performance obligations are limited to contractually obligated revenue on our contracts that exceed one year, which is typically only bid projects, whereas backlog is inclusive of all contracts regardless of length and includes estimated future work over the contractual life of MSAs. Generally, customers are not contractually committed to specific volumes of work under MSAs, and MSAs may be terminated by either party upon notice. Revenue estimates for MSAs are based on historical customer trends. As backlog only includes revenue estimates over the contractual life of MSAs, backlog tends to fluctuate based on the timing of MSA renewals.

Projects included in backlog can be subject to delays or cancellation as a result of regulatory requirements, adverse weather conditions, customer requirements and other factors that could cause actual revenue to differ significantly from the estimates, or cause revenue to be realized in periods other than originally expected.

•Revenue from our U.S. Gas segment totaled $284.5 million, a record high for first fiscal quarter revenue achieved by the segment, representing an increase of $86.8 million, or 43.9%, compared to the prior year period. This growth reflected progress on our initiative to increase work volumes in states that experience less inclement winter weather, significant work on several large bid projects in the Midwest, and generally improved weather compared to an

Table of Contents

especially harsh winter in the prior year period. Gross margin improved to (2.2%) in the current period from (7.5%) in the prior year period, benefiting from increased productivity of crews and more efficient utilization of fixed overhead due to increased volumes.

•Revenue from our Canadian Operations segment totaled $60.0 million, reflecting an increase of $20.2 million, or 50.9%, compared to the prior year period. This increase was driven by the acquisition of Connect, which contributed approximately $23.2 million in revenue and $3.4 million in gross profit in the current year period. As a percentage of revenue, gross profit decreased to 15.2% in the current period as compared to 17.8% in the prior year period. This decrease was driven by timing of gas customer work releases in the current period, and by Connect having slightly lower margins compared to the segment’s legacy operations.

•Revenue from our Union Electric segment totaled $204.1 million, reflecting an increase of $28.6 million, or 16.3%, compared to the prior year period. This increase was driven by new bid project wins. As a percentage of revenue, gross profit increased to 8.9% in the current period as compared to 6.7% in the prior year period. Gross margin for the current year period was positively impacted by a favorable change in estimated cost to complete on an offshore wind project that is nearing completion.

•Revenue from our Non-Union Electric segment totaled $174.6 million, reflecting an increase of $37.4 million, or 27.3%, compared to the prior year period due primarily to higher volumes on new and existing MSAs. Additionally, storm restoration services increased by $6.9 million, accounting for $23.5 million of the segment’s revenue for the current period compared to $16.6 million for the prior year period. Storm restoration services gross profit was relatively flat (down $0.5 million between periods), as storm work performed in the current year period was performed for on-system customers at slightly lower margins.

As a percentage of revenue, Non-Union Electric total gross profit decreased to 8.5% in the current period compared to 11.9% in the prior year period. Approximately half of the decrease in profit percentage was attributable to the decline in storm profitability, with the remainder of the decrease primarily driven by the continued ramp‑up period on a new MSA, for which productivity levels were below normal in the first half of the quarter. Margins on this MSA improved throughout the remainder of the current period and are expected to continue to improve throughout the fiscal year.

Selling, General and Administrative Expenses

Selling, general and administrative costs increased by $6.3 million, or 24.0%, in the current period compared to the prior year period. Salaries and benefits were higher in the current period due to an increase in headcount within our business development function. Additionally, in the current year period we incurred professional fees in support of our strategic initiatives focused on formalizing our multi-year growth strategy, strengthening our succession planning and enhancing the capabilities of key leadership. Bonus and stock-based compensation also increased approximately $2.0 million from the prior year period due to improved operating results.

Interest Expense, Net

The decrease of $5.4 million in interest expense, net in the current period compared to the prior year period was due to a reduction in average debt balance and a reduction in interest rates on outstanding variable-rate borrowings.

Income Tax

Our effective tax rate for the fiscal three months ended March 29, 2026 and March 30, 2025 was 45.0% and 42.3%, respectively. The effective tax rate for the current year period was impacted by the disproportionate amount of non-deductible expenses in relation to loss before income taxes and changes in estimates of pre-tax income. Additionally, differences in income (loss) before income taxes by jurisdiction caused fluctuations in the effective tax rate when comparing periods.

Non-GAAP Financial Measures

We prepare and present our financial statements in accordance with GAAP. However, management believes that EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Loss, Base Revenue, Base Gross Profit and Base Gross Profit Margin, all of which are measures not presented in accordance with GAAP, provide investors with additional useful information in evaluating our performance. We use these non-GAAP measures internally to evaluate performance

Table of Contents

and to make financial, investment and operational decisions. We believe that presentation of these non-GAAP measures provides investors with greater transparency with respect to our results of operations and that these measures are useful for period-to-period comparisons of results. Management also believes that providing these non-GAAP measures helps investors evaluate the Company’s operating performance, profitability and business trends in a way that is consistent with how management evaluates such matters. Because these non-GAAP measures, as defined, exclude some, but not all, items that affect comparable GAAP financial measures, these non-GAAP measures may not be comparable to similarly titled measures of other companies.

EBITDA is defined as earnings before interest, taxes, depreciation and amortization. Adjusted EBITDA is defined as EBITDA adjusted for (i) non-cash stock-based compensation and (ii) separation-related costs. Adjusted EBITDA Margin is defined as the percentage derived from dividing Adjusted EBITDA by revenue. Management believes that EBITDA helps investors gain an understanding of the factors affecting our ongoing cash earnings from which capital investments are made and debt is serviced, and that Adjusted EBITDA provides additional insight by removing certain expenses that are non-recurring and/or non-operational in nature. Management believes that Adjusted EBITDA Margin is useful for the same reason as Adjusted EBITDA, and also provides an additional understanding of how Adjusted EBITDA is impacted by factors other than changes in revenue.

Adjusted Net Loss is defined as net loss adjusted for (i) separation-related costs, (ii) amortization of intangible assets, (iii) non-cash stock-based compensation and (iv) the income tax impact of adjustments that are subject to tax, which is determined using the incremental statutory tax rates of the jurisdictions to which each adjustment relates for the respective periods. Management believes that Adjusted Net Loss helps investors understand the profitability of our business when excluding certain expenses that are non-recurring and/or non-operational in nature.

Base Revenue is defined as total revenue, net adjusted to exclude revenue attributable to storm restoration services. Base Gross Profit is defined as gross profit adjusted to exclude gross profit attributable to storm restoration services. Base Gross Profit Margin is calculated by dividing Base Gross Profit by Base Revenue. Revenue derived from storm restoration services varies from period to period due to the unpredictable nature of weather-related events, and when this type of work is performed, it typically generates a higher profit margin than base infrastructure services projects due to higher contractual hourly rates given the nature of services provided and improved operating efficiencies related to equipment utilization and absorption of fixed costs. While storm restoration services remain a key capability of the Company, Management believes these non-GAAP measures are more suitable disclosures for evaluating fundamental business performance and for comparison purposes.

Using EBITDA as a performance measure has material limitations as compared to net loss, or other financial measures as defined under GAAP, as it excludes certain recurring items, which may be meaningful to investors. EBITDA excludes interest expense net of interest income; however, as we have borrowed money to finance transactions and operations, or invested available cash to generate interest income, interest expense and interest income are elements of our cost structure and can affect our ability to generate revenue and returns for our stockholders. Further, EBITDA excludes depreciation and amortization; however, as we use capital and intangible assets to generate revenue, depreciation and amortization are necessary elements of our costs and ability to generate revenue. Finally, EBITDA excludes income taxes; however, as we are organized as a corporation, the payment of taxes is a necessary element of our operations. As a result of these exclusions from EBITDA, any measure that excludes interest expense net of interest income, depreciation and amortization and income taxes has material limitations as compared to net loss. When using EBITDA as a performance measure, management compensates for these limitations by comparing EBITDA to net loss in each period, to allow for the comparison of the performance of the underlying core operations with the overall performance of the Company on a full-cost, after-tax basis.

As to certain of the items related to these non-GAAP measures: (i) non-cash stock-based compensation varies from period to period due to changes in the estimated fair value of performance-based awards, forfeitures and amounts granted and (ii) separation-related costs represent expenses incurred post-IPO in connection with the separation and stand up of Centuri as its own public company, including costs incurred in association with Southwest Gas Holdings’ sale of its holdings of our common stock, which are not reflective of our ongoing operations and will not recur following the full separation from Southwest Gas Holdings. The most comparable GAAP financial measure and information reconciling the GAAP and non-GAAP financial measures are set forth below.

Liquidity and Capital Resources

Sources and Uses of Liquidity

Our primary liquidity needs have historically related to supporting working capital requirements, funding capital expenditures and servicing our debt. As of March 29, 2026 and December 28, 2025, cash and cash equivalents were $60.3 million and $126.6 million, respectively. We believe our capital resources, including existing cash balances, together with our operating cash flows and borrowings under our credit facilities, are sufficient to meet our financial obligations for the next 12 months and the foreseeable future.

We evaluate our working capital requirements on a regular basis and regularly monitor financial markets and assess general economic conditions for possible impacts to our financial position. Our capital requirements may change to the extent we identify acquisition opportunities, if we experience difficulties collecting amounts due from customers, increase our working capital in connection with new or existing customer programs or repay certain credit facilities.

Cash Flows

The following table presents a summary of our cash flows:


	Fiscal Three Months Ended
(dollars in thousands)	March 29, 2026		March 30, 2025
Net cash (used in) provided by operating activities	$	(35,038)	$	16,676
Net cash used in investing activities	$	(20,605)	$	(23,208)
Net cash used in financing activities	$	(10,499)	$	(27,243)

Operating Activities

Cash flows provided by operating activities are impacted by changes in the timing of demand for our services and related operating margins but can also be affected by working capital needs. Working capital is primarily affected by changes in accounts receivable, contract assets, prepaid expenses and other current assets, accounts payable, accrued expenses, contract liabilities, and income tax accounts, which are primarily related to changes in revenue and related costs of revenue. These working capital balances are affected by changes in revenue resulting from the timing and volume of work performed, variability in the timing of customer billings and collections of receivables, as well as settlement of payables and other liabilities.

Net cash (used in) provided by operating activities for the fiscal three months ended March 29, 2026 was $(35.0) million, compared to $16.7 million for the fiscal three months ended March 30, 2025, representing a decrease in operating cash flows of $51.7 million, which was driven by the following factors:

•Net loss: Our net loss improved $8.4 million from the prior year period. Non-cash expenses did not vary significantly between periods.

•Accounts receivable and contract assets: Cash flow decreased $31.1 million. We had a significant increase in revenue between periods, including on large bid projects in which billings are subject to completion of milestones, and large MSAs in which customer approval is contractually required before invoices can be issued. These contractual requirements are standard to many of our contracts, and the approval process does not typically result in meaningful adjustments to revenue. However, this process occasionally slows down the billing process when customers need to review large volumes of work.

•Accounts payable and accrued expenses: Cash flow decreased $39.2 million as accounts payable and accrued expenses balances at the end of fiscal year 2025 (and therefore paid in the first fiscal quarter of 2026) were significantly higher than at the end of fiscal year 2024, reflecting higher work volumes at the end of the year.

•Contract liabilities: Cash flow increased $7.7 million, as certain new projects led to advance billings to customers.

Investing Activities

Net cash used in investing activities was $20.6 million in the fiscal three months ended March 29, 2026 compared to $23.2 million for the fiscal three months ended March 30, 2025, a decrease of $2.6 million.

Table of Contents

The construction industry is capital intensive, and we expect to continue to incur capital expenditures to meet anticipated needs for our services. For the fiscal three months ended March 29, 2026 and March 30, 2025, we had capital expenditures of $20.2 million and $24.4 million, respectively.

These items were partially offset by proceeds from the sale of property and equipment of $1.6 million and $1.2 million for the fiscal three-month periods ended March 29, 2026 and March 30, 2025, respectively.

Financing Activities

Net cash used in financing activities was $10.5 million for the fiscal three months ended March 29, 2026 compared to $27.2 million for the fiscal three months ended March 30, 2025, a decrease of $16.7 million. The decrease was primarily attributable to lower net payments on our revolving line of credit.

Foreign Operations

While we primarily operate in the United States, we also have operations in Canada. Therefore, changes in the value of Canadian dollars affect our financial statements when translated into U.S. dollars. The revenue from our Canadian operations was approximately 8% and 7% of total revenue for the fiscal three-month periods ended March 29, 2026 and March 30, 2025, respectively. At times, we also enter into transactions in foreign currencies, primarily in Canadian dollars, that subject us to currency risks. We regularly monitor our foreign currency exposure to determine the most effective foreign currency risk mitigation strategies. Currently, we are not party to any foreign currency exchange contracts.

Credit and Securitization Facilities

Term Loan and Revolving Credit Facility

On July 9, 2025, we signed the sixth amendment to our amended and restated credit agreement to refinance and replace in full our existing term loan facility with an $800 million term loan facility, $93.6 million of which is comprised of new term loans used to refinance existing indebtedness and $706.4 million of which was used to refinance existing term loans. This amendment also increased the maximum principal amount of our senior secured revolving credit facility from $400 million to $450 million. This multi-currency facility allows us to request loan advances in either Canadian dollars or U.S. dollars. Amounts borrowed and repaid under the revolving line of credit portion of the facility are available to be re-borrowed. Our term loan facility is set to mature on July 9, 2032, and our revolving credit facility is set to mature on July 9, 2030.

The obligations under our credit agreement are secured by present and future ownership interests in substantially all of our direct and indirect subsidiaries, substantially all of our tangible and intangible personal property, and all products, profits and proceeds of the foregoing. Assets securing the facility totaled $2.3 billion as of March 29, 2026.

During the fiscal three months ended March 29, 2026, the maximum amount outstanding on the combined facility was $708.1 million, at which point $616.0 million was outstanding on the term loan portion of the facility. As of March 29, 2026 and December 28, 2025, $89.7 million and $91.2 million, respectively, was outstanding on the revolving credit facility, in addition to $616.0 million that was outstanding on the term loan portion of the facility as of both March 29, 2026 and December 28, 2025. Also, as of March 29, 2026 and December 28, 2025, there was approximately $303.9 million and $302.4 million, respectively, net of outstanding letters of credit, of unused capacity under the line of credit. We had $68.6 million of unused letters of credit available as of both March 29, 2026 and December 28, 2025.

We are required to maintain a leverage ratio of 4.50 to 1.00 for any future quarter ending prior to September 30, 2026, and 4.00 to 1.00 for any quarter ending on or after September 30, 2026. We are also required to maintain an interest coverage ratio of greater than a minimum of 2.50 to 1.00. We are currently in compliance with all of our financial covenants under the revolving credit facility.

The applicable margin for our revolving credit facility ranges from 1.25% to 2.25% for SOFR and Canadian Overnight Repo Rate Average (“CORRA”) loans and from 0.25% to 1.25% for base rate loans, depending on our net leverage ratio. The term loan facility has a fixed margin of 1.00% for base rate loans and 2.00% for SOFR loans.

Accounts Receivable Securitization

In September 2024, we entered into our Securitization Facility with PNC Bank, National Association (“PNC”) to improve cash flows from trade accounts receivable and used all of the proceeds to pay down our existing debt. Under the Securitization Facility, certain of our designated subsidiaries have sold and/or contributed, and will continue to sell and/or contribute, their accounts receivable and contract assets generated in the ordinary course of their business and certain related assets to the indirect wholly owned bankruptcy-remote Special Purpose Entity (“SPE”) we created specifically for this purpose. The SPE transfers ownership and control of accounts receivable to PNC for payments as set forth in the agreement. We account for accounts receivable sold to the banking counterparty as a sale of financial assets and have derecognized the accounts receivable from our condensed consolidated balance sheet for the current period.

The total outstanding balance of accounts receivable that had been sold and derecognized was $125.0 million as of March 29, 2026. We had no unused capacity on the Securitization Facility as of March 29, 2026.

On May 4, 2026, we signed an amendment to the Securitization Facility which increased the capacity from $125.0 million to $165.0 million.

Equipment Term Loans

As of March 29, 2026, we had six U.S. equipment term loans with initial amounts totaling approximately $150.0 million, with certain owned equipment used as collateral. The loans are serviced in U.S. dollars.
