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, 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 at least the next 12 months;

•Our belief that these 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 are particularly well positioned to capture incremental demand in the offshore wind space given the rapid and continuing expansion of projects in our core geographies, as North America looks to renewable energy sources that can sustain all-time high grid demands;

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

•Our belief that presentation of 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;

•Our belief that any liabilities resulting from any known legal matters, including the City of Chicago matter described in “Note 15 — Commitments and Contingencies — Legal Proceedings”, will not have a material effect on the financial position, results of operations or cash flows;

•Our belief that providing non-GAAP measures helps investors evaluate our operating performance, profitability and business trends in a way that is consistent with how management evaluates such matters;

•Our expectation that the Separation (as defined below)-related costs will continue through at least fiscal year 2025;

•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 rising fuel, labor and material costs could continue to have, a negative effect on our results of operations;

•Our belief that 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;

•Our belief that changes in interest rates on our variable-rate debt could have a positive or negative effect on our business, financial condition and results of operation; and

•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.

Table of Contents

Forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

•Customer project scheduling and duration;

•Weather, and general economic conditions;

•Results of bid work, differences between actual and anticipated outcomes of bid or other fixed-price construction agreements;

•Outcomes from contract and change order negotiations;

•Our ability to successfully procure new work and impacts from work awarded or failing to be awarded work from significant customers, the mix of work awarded, and the amount of work awarded to us following work stoppages or reduction;

•The results of productivity inefficiencies from regulatory requirements, customer supply chain challenges, or otherwise, delays in commissioning individual projects, the ability of management to successfully finance, close on and assimilate any acquired businesses, and changes in our mix of customers, projects, contracts and business;

•Regional or national and/or general economic conditions and demand for our services;

•Price, volatility, and expectations of future prices of natural gas and electricity;

1.Description of Business

Organization Structure

Centuri Holdings, Inc. (“Holdings” and, collectively with the Operating Company (as defined below) and its consolidated subsidiaries, the “Company” or “Centuri”) was formed as a Delaware corporation in June 2023. Holdings was formed for the purpose of completing an initial public offering and facilitating the separation of Centuri Group, Inc. (the “Operating Company”) from Southwest Gas Holdings, Inc. (“Southwest Gas Holdings”) in order to carry on the business of the Operating Company. From formation until April 13, 2024, Southwest Gas Holdings owned 1,000 shares of Holdings common stock, representing 100% of the issued and outstanding shares of common stock of Holdings.

The Operating Company was formed as a wholly owned subsidiary of Southwest Gas Holdings under the laws of the state of Nevada in October 2014 to consolidate and oversee the operations of several utility infrastructure services companies operating throughout North America. On April 13, 2024, Holdings issued 71,664,592 shares of common stock to Southwest Gas Holdings as consideration for the transfer of assets and assumption of liabilities of the Operating Company (“the Separation”). Following the completion of the Separation, the Operating Company became a wholly owned subsidiary of Holdings, and all of Holdings’ operations are conducted through the Operating Company. Prior to its acquisition of the Operating Company as part of the Separation, Holdings had nominal assets, liabilities, and operations.

As Holdings and the Operating Company were both wholly owned by Southwest Gas Holdings as of April 13, 2024, Holdings’ acquisition of the Operating Company as part of the Separation is treated as a reorganization of entities under common control that results in a change in reporting entity. The Operating Company has been determined to be the predecessor for accounting purposes and, accordingly, the condensed consolidated financial statements for periods prior to the combination of Holdings and the Operating Company on April 13, 2024 have been adjusted to combine the previously separate entities for presentation purposes. Amounts for the period from January 2, 2023 through October 1, 2023 and from January 1, 2024 through April 12, 2024 presented in the condensed consolidated financial statements and condensed notes to the financial statements herein represent the historical operations of the Operating Company. The amounts as of September 29, 2024 and for the period from April 13, 2024 reflect the consolidated operations of the Company. For calculation of earnings per share, shares outstanding for all periods prior to April 13, 2024 have been retrospectively adjusted to 71,665,592 to reflect the shares of the Company owned by Southwest Gas Holdings immediately after the combination on April 13, 2024 which resulted in the change in reporting entity. Outstanding shares presented on the Company’s condensed consolidated balance sheet and statement of changes in equity for historical periods have been presented as 1,000 to reflect the shares of Holdings that existed at the formation of Holdings.

Description of Operations

The Company is a pure-play North American utility infrastructure services company that 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 maintenance, retrofitting and installation of electric and natural gas distribution networks, building capacity to meet current and future demands and preparing systems for the expected energy transition. The Company operates through a family of integrated companies working together across different geographies to establish solid customer relationships and a strong reputation for a wide range of capabilities.

Initial Public Offering

On April 17, 2024, the registration statement related to the initial public offering of Centuri’s common stock was declared effective, and Centuri’s common stock began trading on the New York Stock Exchange under the ticker “CTRI” (the “Centuri IPO”) on April 18, 2024. On April 22, 2024, the Centuri IPO was completed through the sale of 14,260,000 shares of Holdings common stock, par value $0.01 per share, including the underwriters’ full exercise of their option to purchase 1,860,000 shares to cover over-allotments, at an initial public offering price of $21.00 per share. On the same day, Icahn Partners and Icahn Partners Master Fund LP, investment entities affiliated with Carl C. Icahn, purchased 2,591,929 shares of Centuri’s common stock in a concurrent private placement at a price per share equal to the IPO price, for gross proceeds of approximately $54.4 million. The total final net proceeds to Centuri from the Centuri IPO and the concurrent private placement, after deducting underwriting discounts and commissions of $18.0 million and offering expenses payable by Centuri of $8.0 million, were $328.0 million. Offering expenses represent costs that were determined to be directly

attributable to the Centuri IPO, and are recorded as a reduction in additional paid-in capital on the Company’s condensed consolidated balance sheet.

As of the closing of the Centuri IPO, Southwest Gas Holdings owned 71,665,592 shares of Centuri common stock, or approximately 81% of the total outstanding shares of Centuri.

2.Basis of Presentation and Summary of Significant Accounting Policies

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 for the fiscal year ended December 31, 2023, as included in the Company’s final IPO prospectus (the “IPO Prospectus”) filed on April 18, 2024 with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended relating to Centuri’s Registration Statement on Form S-1. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations, comprehensive income and cash flows with respect to the interim condensed consolidated financial statements have been included. The results of operations and comprehensive income 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.

As of and prior to December 31, 2023, the Company reported its results under two reportable segments. In January 2024, the Company appointed a new Chief Executive Officer, who was determined by Centuri to be the Company’s chief operating decision maker (“CODM”). Following this appointment, the Company underwent an internal personnel reorganization, causing the Company to re-evaluate its reportable segments based on the information reviewed by the new CODM. Effective July 31, 2024, the Company appointed a new interim Chief Executive Officer who currently acts as the Company’s CODM. However, there have been no changes in the information reviewed by the CODM. See “Note 4 — Segment Information” for additional details.

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 in the Company’s condensed consolidated financial statements relate to fiscal months rather than calendar months. The fiscal nine month period ended September 29, 2024 and October 1, 2023 each had 39 weeks, and the third fiscal quarters of 2024 and 2023 each had 13 weeks.

Cloud Computing Arrangements

The Company capitalizes certain implementation costs incurred in the application development stage of projects related to its cloud computing arrangements (“CCA”) that are service contracts. Capitalized CCA implementation costs are recognized in other assets in the condensed consolidated balance sheets and expensed on a straight-line basis over the fixed, noncancellable term of the associated hosting arrangement plus any reasonably certain renewal periods.

As of September 29, 2024, the net carrying amounts of the Company’s CCA implementation costs were $27.6 million. Amortization of CCA-related assets is classified as a cash operating expense (i.e., not included in amortization or depreciation in the Company’s condensed consolidated financial statements). CCA implementation expenditures are included within cash flows from operating activities in the condensed consolidated statement of cash flows.

Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The update improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This update is effective beginning with the Company’s 2024 fiscal year annual reporting period, and will be effective for

Table of Contents

interim reporting periods in the Company’s fiscal 2025, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this update will have on its disclosures.

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 is effective beginning with the Company’s 2025 fiscal year annual reporting period, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this update will have on its disclosures.

In March 2024, the SEC issued the final rules under SEC Release No. 33-11275, “The Enhancement and Standardization of Climate-Related Disclosures for Investors.” In April 2024, the SEC voluntarily stayed the new rules as a result of pending legal challenges. Absent the stay and the result of pending legal challenges, these rules will require registrants to disclose certain climate-related information, including Scope 1 and Scope 2 greenhouse gas emissions and other climate-related topics, in registration statements and annual reports, when material. Disclosure requirements, absent the results of pending legal challenges, will begin phasing in with the annual reporting for the fiscal year ending 2027 based on Centuri’s current status as a non-accelerated filer. 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				Fiscal Nine Months Ended
	September 29, 2024		October 1, 2023		September 29, 2024		October 1, 2023
Contract Type:
Master services agreements	$	569,000	$	631,913	$	1,571,701	$	1,830,242
Bid contracts	151,053		142,976		348,450		403,719
Total revenue	$	720,053	$	774,889	$	1,920,151	$	2,233,961

Unit-price contracts	$	412,871	$	440,787	$	1,119,161	$	1,191,889
Time and materials contracts	168,940		168,465		417,900		520,350
Fixed-price contracts	138,242		165,637		383,090		521,722
Total revenue	$	720,053	$	774,889	$	1,920,151	$	2,233,961

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


	September 29, 2024		December 31, 2023
Current contract assets	$	288,568	$	269,808
Non-current contract assets	24,097		214
Contract assets, total	312,665		270,022
Contract liabilities	(21,894)		(43,694)
Net contract assets	$	290,771	$	226,328

Contract assets primarily consist of revenue earned on contracts in progress in excess of billings, which relates to the Company’s rights to consideration for work completed but not billed and/or approved at the reporting date as well as contract retention balances. Contract assets that are not expected to be invoiced and collected within a year of the financial statement date (“Non-current contract assets”) are included in other assets on the condensed consolidated balance sheets. Revenue earned on contracts in progress in excess of billings are transferred to accounts receivable when the rights become unconditional. Non-current contract assets as of September 29, 2024 included approximately $13.2 million of net recovery claims. Claims occur when there is a dispute regarding a change in the scope of work and associated price for work already performed. The Company records estimated claims 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 with the variable consideration is resolved.

Total contract assets increased $42.6 million during the fiscal nine months ended September 29, 2024 due primarily to timing of billings. 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

Table of Contents

addition, many of 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 change in the contract liability balance of $21.8 million from December 31, 2023 to September 29, 2024 was primarily due to revenue recognized that was included in the balance as of December 31, 2023, after which time it became earned and the balance was ultimately realized.

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. In the event contract assets or contract liabilities are expected to be recognized more than one year from the financial statement date, the Company classifies those amounts as long-term contract assets or contract liabilities, included in other assets or other long-term liabilities, respectively, on the condensed consolidated balance sheets. Similarly, accounts receivable balances expected to be collected beyond one year are recorded as long-term within other assets.

For contracts with an original duration of one year or less, the Company uses the practical expedient applicable to such contracts and does not consider the time value of money. Further, because of the short duration of these contracts, 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 September 29, 2024, the Company had 42 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 September 29, 2024 was $249.1 million. The Company expects to recognize the 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):


	September 29, 2024		December 31, 2023
Billed on completed contracts and contracts in progress	$	253,809	$	348,021
Other receivables	2,115		1,945
Accounts receivable, gross	255,924		349,966
Allowance for doubtful accounts	(2,905)		(2,512)
Accounts receivable, net	$	253,019	$	347,454

4.Segment Information

As of and prior to December 31, 2023, the Company reported its results under the following two reportable segments: Gas Utility Services and Electric Utility Services. In January 2024, the Company appointed a new Chief Executive Officer, who was determined by Centuri to be the Company’s CODM. Following this appointment, the Company underwent an internal personnel reorganization, causing the Company to re-evaluate its reportable segments based on the information reviewed by the new CODM. The Company determined that it was appropriate to re-align its reporting structure from the following two reportable segments: (i) Gas Utility Services; and (ii) Electric Utility Services, to the following four reportable segments: (i) U.S. Gas Utility Services (“U.S. Gas”); (ii) Canadian Gas Utility Services (“Canadian Gas”); (iii) Union Electric Utility Services (“Union Electric”); and (iv) Non-Union Electric Utility Services (“Non-Union Electric”). The U.S. Gas and Canadian Gas businesses have historically been part of the Gas Utility Services segment, and the Union Electric and Non-Union Electric businesses have historically been part of the Electric Utility Services segment. All prior year segment financial information has been recast to reflect the new segment structure. Effective July 31, 2024, the Company appointed a new interim Chief Executive Officer who currently acts as the Company’s CODM. However, there has been no

Table of Contents

change in the information reviewed by the CODM. The CODM allocates resources to and assesses the performance of each reportable segment using information about the reportable segment’s gross profit.

U.S. Gas

U.S. Gas provides comprehensive services, including maintenance, repair and installation for local natural gas distribution utilities (“LDCs”) throughout the United States focused on the modernization of customers’ infrastructure. The work performed within this segment includes solutions for all stages of utility work and is performed primarily within the distribution, urban transmission and end-user infrastructure, rather than large-scale, project-based, cross-country transmission. The Company is able to cater to the needs of its gas utility services customers by serving union and non-union markets.

Canadian Gas

Canadian Gas provides comprehensive services, including maintenance, repair and installation for LDCs focused on the modernization of customers’ infrastructure. The work performed within this segment includes solutions for all stages of utility work and is performed primarily within the distribution, urban transmission and end-user infrastructure, rather than large-scale, project-based, cross-country transmission. Canadian Gas serves union markets.

Union Electric

Union Electric provides a comprehensive set of electric utility services encompassing maintenance, repair, upgrade and expansion services for urban transmission and local distribution infrastructure within union markets. The work is focused primarily on recurring local distribution and urban transmission services under master service agreements (“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.

Non-Union Electric

Non-Union Electric provides a comprehensive set of electric utility services encompassing maintenance, repair, upgrade and expansion services for urban transmission and local distribution infrastructure within non-union markets. The work 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.

Other

Other primarily consists of corporate and non-allocated costs, including corporate facility costs, non-allocated corporate salaries, benefits and incentive compensation. Other also includes certain industrial service activities that do not meet the criteria of a reportable segment.

Table of Contents

Revenue and gross profit by segment were as follows (in thousands):

Separate measures of the Company’s assets and cash flows, with the exception of capital expenditures, are not produced or utilized by management to evaluate segment performance.

Capital expenditures by segment were as follows (in thousands):


	Fiscal Three Months Ended				Fiscal Nine Months Ended
	September 29, 2024		October 1, 2023		September 29, 2024		October 1, 2023
U.S. Gas	$	7,276	$	14,170	$	31,485	$	43,900

Consolidated capital expenditures	$	19,531	$	25,858	$	66,093	$	79,610

(1)Management determined that certain cash outflows incurred during the six months ended June 30, 2024 related to the implementation of a cloud computing arrangement were incorrectly reported as capital expenditures instead of as operating cash outflows (as required by ASC 350-40). The Company corrected the classification of these expenditures in the condensed consolidated statement of cash flows for the nine months ended September 29, 2024. The Company quantitatively and qualitatively assessed the impact of this error on previously issued financial statements and concluded the impact was not material and will revise the first and second quarter 2024 amounts in future filings.

Table of Contents

Foreign Operations

The Company recorded revenue in Canada of approximately $53.5 million (7% of consolidated revenue) and $64.3 million (8%) during the fiscal three months ended September 29, 2024 and October 1, 2023, respectively, and $141.1 million (7%) and $178.1 million (8%) for the fiscal nine months ended September 29, 2024 and October 1, 2023, respectively.

5.Per Share Information

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

As discussed in “Note 1 — Description of Business”, shares outstanding for all periods before April 13, 2024 have been retrospectively restated to be 71,665,592, reflecting the shares issued as part of the combination of Holdings and the Operating Company plus the 1,000 Holdings shares that were issued to Southwest Gas Holdings upon formation.

The amounts used to compute basic and diluted earnings per share attributable to common stock consisted of the following (in thousands):


	Fiscal Three Months Ended				Fiscal Nine Months Ended
	September 29, 2024		October 1, 2023		September 29, 2024		October 1, 2023
Amounts attributable to common stock:
Net (loss) income attributable to common stock	$	(3,652)	$	16,182	$	(17,023)	$	24,484

Weighted average shares:
Weighted average shares outstanding for basic and diluted earnings per share attributable to common stock	88,518		71,666		81,679		71,666

There were no dilutive securities for any periods presented, and therefore the denominator for basic and diluted earnings per share was the same for all periods. There were a de minimis amount of potentially dilutive securities that were antidilutive in the current year periods presented due to the Company recording a net loss for the fiscal three and nine months ended September 29, 2024.

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 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 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 and its related subsidiaries have no continuing involvement in the transferred accounts receivable, other than collection and administrative responsibilities, and, once sold, the accounts receivable are no longer available to satisfy the creditors or the related subsidiaries. The Company has not recorded any servicing asset or liability related to this continuing involvement as the Company has determined it is compensated adequately for its servicing role. 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.

In addition, Centuri Group, Inc. has agreed to guarantee the performance of the indirect wholly-owned subsidiaries of the Company and itself as the servicer of their respective obligations under the documentation for the Securitization Facility. Centuri Group, Inc. is not guaranteeing the collectibility of any assets transferred in the Securitization Facility or the

Table of Contents

creditworthiness of the related obligors. The Securitization Facility is subject to yield charges based upon a rate as specified in the documentation for the Securitization Facility. These yield charges are recorded in interest expense, net on the Company’s condensed consolidated statement of operations, and were not material for the fiscal three or nine months ended September 29, 2024. The Company may incur a recourse obligation in limited circumstances, but the Company has determined this liability is not material.

The total outstanding balance of accounts receivable that had been sold and derecognized was $125.0 million as of September 29, 2024. Additionally, the SPE owned accounts receivable and contract assets of $60.6 million and $115.5 million, respectively, as of September 29, 2024, which were not sold to PNC but were pledged as collateral. These balances are primarily included in accounts receivable, net and contract assets (and the accompanying related party captions) in the Company’s condensed consolidated balance sheet, with certain non-current balances being included in other assets. For the nine months ended September 29, 2024, the Company received $125.0 million in cash proceeds from the Securitization Facility, which is recorded in operating cash flows on the condensed consolidated statement of cash flows, and had no repayments on the Securitization Facility. As of September 29, 2024, the Company had no available capacity under the Securitization Facility.

7.Noncontrolling Interests

In connection with the acquisition of Linetec Services, LLC (“Linetec”) in November 2018, the previous owner initially retained a 20% noncontrolling equity interest in the entity, which was reduced to 10% as of December 31, 2023. Additionally, in connection with the acquisition of Riggs Distler & Company, Inc. (“Riggs Distler”), certain members of Riggs Distler management acquired a 1.42% noncontrolling interest in the parent company of Riggs Distler, Drum Parent LLC (formerly Drum Parent, Inc.) (“Drum”), which was reduced to 1.41% as of December 31, 2023. In exchange for the noncontrolling interest in Drum, the Company received a combination of cash and promissory notes (which accrued interest at the prime rate plus 2%) from the noncontrolling interest holders. The Company maintained the right, subject to the passage of time or occurrence of certain triggering events, to repurchase the noncontrolling interests in both Linetec and Riggs Distler at fair value.

In March 2024, the parties agreed to redeem the remaining 10% equity interest for $92.0 million, which resulted in the Company owning all of the equity interest in Linetec. The Company paid the $92.0 million in April, in accordance with the agreement.

During the first quarter of 2024, the Company redeemed various Drum units in satisfaction of all outstanding promissory notes and forgave unpaid interest owed from the Riggs Distler noncontrolling interest holders and in exchange obtained the 0.47% portion of equity interest in Drum that had been funded through these notes. Additionally, during the first quarter of 2024, the Company reached an agreement to purchase a 0.13% noncontrolling interest in Drum for $0.8 million. The remaining noncontrolling interest in Drum outstanding as of September 29, 2024 was 0.81%.

Significant changes in the value of the redeemable noncontrolling interests, above a floor determined at the establishment date, are recognized as they occur, and the carrying value is adjusted as necessary at each reporting date. The fair value is estimated using a market approach that utilizes certain financial metrics from guideline public companies of similar industry and operating characteristics. Based on the fair value model employed, the estimated redemption value of the Linetec redeemable noncontrolling interest increased by $0.2 million during the first fiscal quarter of 2024 to the value at which it was redeemed. The estimated redemption value of the Riggs Distler redeemable noncontrolling interest increased by $1.8 million during the fiscal nine month period ended September 29, 2024.

Adjustments to the redemption values have historically impacted retained earnings, as reflected on the condensed consolidated statements of changes in equity. As the Company was in an accumulated deficit position prior to any redemption value adjustment during the fiscal nine months of 2024, the redemption value adjustments during this period were recorded as reductions in additional paid-in capital.

8.Goodwill and Intangible Assets

During fiscal 2024, the Company changed its reporting units to align with changes in its organization structure, and as a result, the Company’s reporting units are the same as its reportable segments. Prior to and after the reporting unit restructure, the Company qualitatively assessed its reporting units for potential goodwill impairment, and with the exception of Riggs Distler (which was impaired in the fourth fiscal quarter of 2023), the results of the qualitative assessments did not indicate that it was more likely than not that the fair value of each reporting unit analyzed was less than the carrying value including goodwill, and no goodwill impairment was recognized.

Changes in the carrying amount of goodwill of each of the Company’s reportable segments were as follows (in thousands):


	U.S. Gas		Canadian Gas		Union Electric (1)		Non-Union Electric		Total
Balances as of December 31, 2023	$	58,160	$	93,911	$	56,499	$	167,322	$	375,892

(1)Fair values as of September 29, 2024 and December 31, 2023 were determined using the Company’s credit rating.

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, which in addition to funding the Riggs Distler acquisition, refinanced the Company’s previous $590 million loan facility. 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 to be re-borrowed. 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 September 29, 2024 totaled $2.0 billion. The credit agreement also contains a restriction on dividend payments with a calculated available amount generally defined as 50% of the Company’s rolling twelve-month consolidated net income adjusted for certain items, such as parent capital contributions, redeemable noncontrolling interest payments, and dividend payments, among other adjustments, as applicable. The term loan facility matures on August 27, 2028, and the revolving credit facility matures on August 27, 2026.

On May 31, 2023, the Company entered into an amendment to the amended and restated credit agreement to transition the interest rate benchmark for the term loan facility from London Interbank Offered Rate (“LIBOR”) to Secured Overnight Financing Rate (“SOFR”) benchmarks. The applicable margins for the term loan facility remained 1.50% for base rate loans and are 2.50% for SOFR loans. Furthermore, the Company’s Canadian entities may borrow under the revolving credit facility with interest rates based on either a “base rate” or the Canadian Overnight Repo Rate Average (“CORRA”) plus the applicable margin, at the borrower’s option. The weighted average interest rate on the term loan facility was 7.87% and 7.97% as of September 29, 2024 and December 31, 2023, respectively.

On November 4, 2022, November 13, 2023, and March 22, 2024, the Company amended the financial covenants of the revolving credit facility. Under the amended terms of the revolving credit facility, the Company was required to maintain certain net leverage ratios, however it also provided that, in the event that a “Qualified IPO” (as defined therein) is consummated prior to March 31, 2025, the maximum net leverage ratio financial covenant would be reduced based on the amount of net proceeds received from such Qualified IPO. Pursuant to these terms, the completion of the Qualified IPO resulted in a change to the maximum net leverage ratio. Based on the amount of proceeds received, the Company is now required to maintain a net leverage ratio of less than a maximum of 5.25 to 1.00 from April 18, 2024 through June 30, 2024, 5.00 to 1.00 from July 1, 2024 through September 29, 2024, 4.25 to 1.00 from September 30, 2024 through December 29, 2024, and 4.00 to 1.00 thereafter. Under the amended terms of the revolving credit facility, the Company is also required to maintain an interest coverage ratio of greater than a minimum of 2.00 to 1.00 from January 1, 2024 through December 29, 2024, and 2.50 to 1.00 thereafter. As of September 29, 2024, the Company was in compliance with all of the

Table of Contents

financial covenants under the revolving credit facility. The November 4, 2022 amendment to the amended and restated credit agreement increased a letter of credit sub-facility from $100 million to $125 million, and also transitioned the interest rate benchmark for the revolving credit facility from LIBOR to SOFR benchmarks. On May 13, 2024, the Company also amended its revolving credit facility to transition from Canadian Dollar Offered Rate benchmarks to CORRA benchmarks for Canadian dollar borrowing under its revolving credit facility. The applicable margin for the revolving credit facility now ranges from 1.0% to 2.5% for SOFR and CORRA loans and from 0.0% to 1.5% for “base rate” loans, depending on the Company’s net leverage ratio. The Company is also 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. The weighted average interest rate on the revolving credit facility was 7.23% and 7.66% as of September 29, 2024 and December 31, 2023, respectively.

As of September 29, 2024 and December 31, 2023, the Company had borrowings outstanding of $0.8 billion and $1.1 billion, respectively, 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 $218.4 million, net of outstanding letters of credit, of unused capacity on the revolving line of credit as of September 29, 2024. The Company had $59.8 million and $48.6 million of unused letters of credit available as of September 29, 2024 and December 31, 2023, respectively. Debt issuance costs associated with the Company’s line of credit are amortized over the term of the related line of credit. As of September 29, 2024 and December 31, 2023, there was $3.4 million and $4.2 million, respectively, in debt issuance costs recorded in other assets on the condensed consolidated balance sheets.

As of September 29, 2024, the Company had $72.7 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 are amortized over the term of the related debt, which approximates the effective interest method. As of September 29, 2024 and December 31, 2023, debt issuance costs of $12.6 million and $17.1 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 each of fiscal three month periods ended September 29, 2024 and October 1, 2023, amortization of debt issuance costs was $1.5 million and $1.3 million, respectively. During the fiscal nine month periods ended September 29, 2024 and October 1, 2023, amortization of debt issuance costs was $4.1 million and $3.8 million, respectively. The Company incurred a debt extinguishment loss of $1.7 million in the third quarter of 2024 related to the write-off of debt issuance costs associated with its term loan. This loss was recorded within interest expense, net on the Company’s condensed consolidated statement of operations.

The Company currently has seven equipment term loans with initial amounts totaling approximately $170 million, with certain owned equipment used as collateral. The loans are serviced in U.S. dollars. These term loans have prepayment penalties for the first three years of the agreements. The Company did not incur any material prepayment penalties during the first fiscal nine months of 2024 or 2023.

The fair value of the Company’s debt as of September 29, 2024 and December 31, 2023 was $0.9 billion and $1.2 billion, respectively. 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.

With the proceeds obtained from the Centuri IPO, the Company paid down $156.0 million of debt under its revolving credit facility and $160.0 million of debt under its term loan facility on April 22, 2024. The Company made an additional prepayment on its term loan debt in September 2024 using $100.0 million of the proceeds from the sale of accounts receivable discussed in “Note 6 — Accounts Receivable Securitization Facility”.

11.Leases

The Company has operating and finance leases for corporate and field offices, 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 14 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 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 September 29, 2024, 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):

12.Income Taxes

Historically, including in the first and second quarters of 2024, the Company has calculated the provision for income taxes for interim periods by applying an estimate of the annual effective tax rate for the full year to “ordinary” income or loss. However, because fluctuations in estimated ordinary income can result in significant changes in the estimated annual effective tax rate, the Company determined that this method does not provide a reliable estimate for the fiscal nine months ended September 29, 2024. As such, the Company calculates its interim income tax expense for the fiscal nine months ended September 29, 2024 on a discrete basis, consistent with the guidance in ASC 740-270, Income Taxes - Interim Reporting.

The Company’s effective tax rate for the fiscal three months ended September 29, 2024 and October 1, 2023 was 119.9% and 37.2%, respectively, and for the fiscal nine months ended September 29, 2024 and October 1, 2023 was (3.1)% and 37.3%, respectively. The effective tax rate in the current year periods was impacted by the Company’s use of the actual effective tax rate instead of the estimated annual effective tax rate method used in prior interim periods, as well as the disproportionate amount of non-deductible expenses in relation to income before income taxes.

Table of Contents

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. 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.

As of September 29, 2024 and December 31, 2023, the total amount of unrecognized tax benefits relating to uncertain tax positions was $0.5 million.

As of September 29, 2024, with certain exceptions, the Company is no longer subject to U.S. federal, state, local, or Canadian examinations for years before fiscal 2018. As discussed in “Note 14 — Related Parties”, the Company is a party to a tax matters agreement with Southwest Gas Holdings. The agreement outlines the method in which the Company calculates its income tax liability and the manner in which it either reimburses Southwest Gas Holdings for taxes owed or is reimbursed for credits and net operating losses used.

There were no significant related party contract liabilities as of September 29, 2024 or December 31, 2023 with Southwest Gas Corporation.

Additionally, certain costs incurred by Southwest Gas Holdings have been allocated to Centuri, which are settled in cash during the normal course of operations. The Company recorded allocated costs of $0.2 million for the fiscal three months ended October 1, 2023, and $0.5 million and $1.0 million allocated costs for the fiscal nine months ended September 29, 2024 and October 1, 2023, respectively. The Company did not record any allocated costs for the fiscal three months ended September 29, 2024. These costs are recorded within selling, general and administrative expenses on the Company’s condensed consolidated statements of operations.

In connection with the Separation and the Centuri IPO, Holdings entered into several agreements with Southwest Gas Holdings on April 11, 2024, governing the relationship of the two parties after the Separation and Centuri IPO. These agreements are summarized below and also discussed in more detail within the IPO Prospectus in the section entitled “The Separation Transactions.”

•Separation Agreement: Sets forth the agreements with Southwest Gas Holdings regarding the principal actions to be taken in connection with the Separation and govern, among other matters, (1) the allocation of assets and liabilities to Centuri and Southwest Gas Holdings (including Centuri’s indemnification obligations, for potentially

Table of Contents

uncapped amounts, for certain liabilities relating to Centuri’s business activities), (2) certain matters with respect to the Centuri IPO and subsequent disposition transactions by Southwest Gas Holdings, and (3) certain covenants, as described in the IPO Prospectus, regarding Southwest Gas Holdings’ right to designate members to Centuri’s Board, approve certain Company actions, and receive information and access rights.

•Tax Matters Agreement: Sets forth responsibilities and obligations with respect to all tax matters, including tax liabilities (including responsibility and potential indemnification obligations for taxes attributable to Holdings’ business and taxes arising, under certain circumstances, in connection with the Separation and a distribution to Southwest Gas Holdings stockholders that is currently intended to be tax-free to Southwest Gas Holdings and its stockholders, if effected), tax attributes, tax contests and tax returns (including Centuri’s continued inclusion in the U.S. federal consolidated group tax return, and certain other combined or similar group tax returns, with Southwest Gas Holdings for applicable tax periods following the Separation, and Centuri’s continuing joint and several liability with Southwest Gas Holdings for such tax returns). As of September 29, 2024 and December 31, 2023, there were no amounts due to or from Southwest Gas Holdings related to income taxes.

•Registration Rights Agreement: Grants to Southwest Gas Holdings certain registration rights with respect to the shares of Centuri common stock owned by Southwest Gas Holdings following the Centuri IPO.

The Company’s former chief executive officer and current member of the Company’s Board of Directors, began serving as the chief executive officer and president of one of the Company’s existing customer in August of 2024. Revenue with this customer for the fiscal three and nine months ended September 29, 2024 was $36.7 million and $100.0 million, respectively. As of September 29, 2024, approximately $11.3 million (4.5%), and $22.0 million (7.6%) of the Company’s accounts receivable and contract assets, respectively, were related to contracts with this customer. There were no significant contract liabilities as of September 29, 2024 with this customer.

In November 2021, certain members of Riggs Distler management acquired a 1.42% interest in Drum. See “Note 7 — Noncontrolling Interests” for more information. A portion of the redeemable noncontrolling interest acquired was funded through promissory notes made to noncontrolling interest holders bearing interest at the prime rate plus 2%. The promissory notes are payable by the noncontrolling interest holders upon certain triggering events, including, but not limited to, termination of employment or the redemption of any interest under the agreement. The promissory notes and related interest income are recorded in additional paid-in capital, a component of total equity, on the condensed consolidated balance sheets. During the first quarter of 2024, the Company redeemed various Drum units in satisfaction of all outstanding promissory notes and forgave unpaid interest owed from the Riggs Distler noncontrolling interest holders and in exchange obtained the 0.47% portion of equity interest in Drum that had been funded through these notes. Additionally, during the first quarter of 2024, the Company reached an agreement to purchase a 0.13% noncontrolling interest in Drum for $0.8 million. The remaining noncontrolling interest in Drum outstanding as of September 29, 2024 was 0.81%.

15.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. 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 intends to have the case reviewed by the Circuit Court of Cook County Illinois. The Company intends to vigorously pursue this matter, however, the Company cannot accurately predict the ultimate outcome. With the ultimate timing and conclusion unknown, the Company has not recognized any incremental amount in income to the extent NPL’s claims for relief are awarded in the Company’s favor. Further, to the extent the Company is not successful in collecting the withheld receivables, this matter could result in an additional significant loss. The Company can provide no assurance as to whether or when there will be material developments in these matters. 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 the 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 clauses that become effective upon a change in control of the Company. Upon the 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 responsibility.

Concentration of Credit Risk

The Company provides full-service utility 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 10%. No customers accounted for more than 10% of revenue during the fiscal three or nine month periods ended September 29, 2024 or October 1, 2023. No customer had a combined accounts receivable and contract asset balance above 10% of the consolidated accounts receivable and contract assets balance. One Union Electric customer had a combined accounts receivable and contract asset balance of $84.3 million as of December 31, 2023, which was approximately 14% of the consolidated balance of these accounts.

The Company primarily uses three financial banking institutions. The Company’s cash on deposit with these financial institutions exceeded the federal insurability limits as of September 29, 2024. 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 or provide services 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 September 29, 2024, 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 September 29, 2024, the estimated total amount of outstanding performance and payment bonds was approximately $637.3 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 $289.6 million as of September 29, 2024.

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.

The first fiscal nine months of 2024 and 2023 ended on September 29, 2024 and October 1, 2023, respectively, and each period had 39 weeks. The third fiscal quarters of 2024 and 2023 each had 13 weeks.

Overview

Company Overview

We are a leading, pure-play North American utility infrastructure services company that partners with regulated utilities to maintain, upgrade and expand the energy network that powers millions of homes and businesses. We serve as long-term strategic partners to, and an extension of, North America’s electric, gas and combination utility providers, delivering a wide range of infrastructure solutions. Our service offerings primarily consist of the modernization of utility infrastructure through the maintenance, retrofitting and installation of electric and natural gas distribution networks, and building capacity to meet current and future demands. We also serve complementary, attractive and growing end markets such as renewable energy associated with the expected energy transition and 5G datacom. 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.

Separation from Southwest Gas Holdings

We were incorporated in Delaware in June 2023 as a wholly owned subsidiary of Southwest Gas Holdings, Inc. (“Southwest Gas Holdings”). We were formed for the purpose of completing an initial public offering, facilitating the separation of the Operating Company from Southwest Gas Holdings and other related transactions in order to carry on the business of the Operating Company, our predecessor for financial reporting purposes. Prior to April 13, 2024, Southwest Gas Holdings owned 1,000 shares of our common stock, representing 100% of the issued and outstanding shares of our common stock. On April 13, 2024, we issued 71,664,592 shares of common stock to Southwest Gas Holdings as consideration for the transfer of assets and assumption of liabilities of the Operating Company (the “Separation”). Following the completion of the Separation, the Operating Company became our wholly owned subsidiary, and all of our operations are conducted through the Operating Company. On April 17, 2024, the registration statement related to the initial public offering of our common stock was declared effective, and our common stock began trading on the New York Stock Exchange under the ticker “CTRI” (the “Centuri IPO”) on April 18, 2024.

On April 22, 2024, the Centuri IPO was completed through the sale of 14,260,000 shares of our common stock, par value $0.01 per share, including the underwriters’ full exercise of their option to purchase 1,860,000 shares to cover over-allotments, at an initial public offering price of $21.00 per share. On the same day, Icahn Partners and Icahn Partners Master Fund LP, investment entities affiliated with Carl C. Icahn, purchased 2,591,929 shares of our common stock in a concurrent private placement at a price per share equal to the IPO price, for gross proceeds of approximately $54.4 million. The total net proceeds to us from the Centuri IPO and the concurrent private placement, after deducting underwriting discounts and commissions of $18.0 million and offering expenses payable of $8.0 million, were $328.0 million. As of the closing of the Centuri IPO, Southwest Gas Holdings owned 71,664,592 shares of our common stock, or approximately 81% of the total outstanding shares of our common stock.

Table of Contents

We are incurring certain costs in connection with our establishment as a standalone public company (the “Separation-related costs”). We expect the Separation-related costs to continue through at least fiscal year 2025. For additional information about the Separation, see “The Separation Transactions—The Separation” and “Certain Relationships and Related Person Transactions—Agreements between Southwest Gas Holdings and Our Company” within the IPO Prospectus. Additionally, see “Note 14 — Related Parties” to the Centuri condensed consolidated financial statements for a summary of agreements we entered into with Southwest Gas Holdings on April 11, 2024 governing our relationship with Southwest Gas Holdings following the Centuri IPO.

Appointment of Chief Executive Officer

As disclosed in our Form 8-K dated November 5, 2024, on November 4, 2024, Christian (Chris) Brown was appointed as President and Chief Executive Officer of the Company and as a member of our Board of Directors (“the Board”) with a term expiring at the annual meeting to be held in 2025, effective December 3, 2024. In connection with this appointment, William J. Fehrman notified the Board of his resignation as a Director of the Board, effective December 3, 2024. Mr. Fehrman’s resignation was not due to any disagreement with the Company on any matter relating to the Company’s operations, policies or practices.

Segment Information

As of and prior to December 31, 2023, we reported our results under the following two reportable segments: Gas Utility Services and Electric Utility Services. In January 2024, we appointed a new Chief Executive Officer, who we determined to be our chief operating decision maker (“CODM”). Following this appointment, we underwent an internal personnel reorganization, causing us to re-evaluate our reportable segments based on the information reviewed by the new CODM. We determined that it was appropriate to re-align our reporting structure from the following two reportable segments: (i) Gas Utility Services; and (ii) Electric Utility Services, to the following four reportable segments: (i) U.S. Gas Utility Services (“U.S. Gas”); (ii) Canadian Gas Utility Services (“Canadian Gas”); (iii) Union Electric Utility Services (“Union Electric”); and (iv) Non-Union Electric Utility Services (“Non-Union Electric”). The U.S. Gas and Canadian Gas businesses have historically been part of our Gas Utility Services segment, and the Union Electric and Non-Union Electric businesses have historically been part of our Electric Utility Services segment. All prior year segment financial information has been recast to reflect the new segment structure. Effective July 31, 2024, we appointed an interim Chief Executive Officer who currently acts as the Company’s CODM. However, there has been no change in the information reviewed by the CODM.

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, 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 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 had, and could continue to 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.

Table of Contents

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 recent 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 well-positioned to support growing customer attention in achieving environmental objectives through infrastructure construction and maintenance. Additionally, our acquisition of Riggs Distler in 2021 positions us to benefit from the necessary development of onshore infrastructure to support offshore wind and power development. We believe we are particularly well-positioned to capture incremental demand in the offshore wind space given the rapid and continuing expansion of projects in our core geographies, as North America looks to renewable energy sources that can sustain all-time high grid demands.

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 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

Table of Contents

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

Our operations are affected by increases in prices, whether caused by inflation, rising interest rates or other economic factors. We attempt to recover anticipated increases in the cost of labor, equipment, fuel and materials 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, the third quarter of 2024 was not significantly impacted by inflation when compared to the same quarter in the prior year, as we have begun to see slower growth in prices in recent periods.

Backlog

Backlog represents estimates of revenue to be realized under long-term master service agreements (“MSAs”) and bid agreements. 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 under 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. 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. Backlog as of September 29, 2024 was approximately $4.3 billion, approximately 87% of which related to MSAs, and backlog as of December 31, 2023 was approximately $5.1 billion, approximately 90% of which related to MSAs.

Results of Operations

Our results of operations, on a consolidated basis and by segment, for the fiscal three and nine months ended September 29, 2024 and October 1, 2023 are set forth below.

Three months ended September 29, 2024 compared to the three months ended October 1, 2023

NM — Percentage is not meaningful

•Revenue from our U.S. Gas segment totaled $366.1 million, reflecting a decrease of $29.7 million, or 7.5%, compared to the prior year period. This decrease was largely due to a reduction in net volumes under existing customer MSAs. As a percentage of revenue, gross profit decreased to 7.6% in the current period from 13.2% in the same period from the prior year. Profitability was negatively affected primarily by mix of bid work, as the same quarter in the prior year benefited from a highly profitable bid project. Additionally, the current quarter was impacted by lower utilization of fixed costs stemming from reduced revenues, lower productivity on MSA and bid jobs, caused in part by higher rental and repairs and maintenance costs due to equipment issues experienced, and higher costs of insurance claims. Revenue from Southwest Gas Corporation totaled $27.2 million for the current period compared to $29.3 million in the prior year period.

•Revenue from our Canadian Gas segment totaled $50.4 million, reflecting a decrease of $4.2 million, or 7.8%, compared to the prior year period. This decrease was primarily due to a reduction in net volumes under existing

Table of Contents

MSAs. As a percentage of revenue, gross profit increased to 23.4% in the current period as compared to 18.4% in the same period from the prior year primarily due to favorable changes in mix of work.

•Revenue from our Union Electric segment totaled $171.7 million, reflecting a decrease of $32.5 million, or 15.9%, compared to the prior year period. This decrease was driven by a decline in offshore wind revenue of $38.0 million due to timing of projects, partially offset by increased revenue on bid projects. Storm restoration services revenue for the Union Electric segment was $6.7 million for the current period compared to $10.8 million for the prior year period. As a percentage of revenue, gross profit increased to 9.0% in the current period as compared to 5.7% in the prior year period as the segment experienced higher margins on their increased bid volumes.

•Revenue from our Non-Union Electric segment totaled $128.8 million, reflecting an increase of $18.1 million, or 16.4%, compared to the prior year period. This increase was primarily due to revenue from storm restoration services which accounted for $34.7 million of the segment’s revenue for the current period, compared to $8.1 million for the prior year period. As a percentage of revenue, gross profit increased to 16.6% in the current period compared to 11.6% in the prior year period, primarily due to the higher profitability of storm work, mainly resulting from the impacts of Hurricane Beryl early in the quarter and Hurricane Helene in the last few days of the period.

•Revenue from non-reportable segments decreased due to timing of bid projects.

Selling, General and Administrative Expenses

Selling, general and administrative costs decreased by $0.8 million, or 2.8%, in the current period compared to the same period in the prior year. The Company incurred $1.4 million in transaction fees in association with its accounts receivable securitization facility (“Securitization Facility”) in the current quarter, but incurred lower payroll costs than in the same quarter of the prior year due in part to the restructuring activities that took place in prior periods.

Amortization of Intangible Assets

Amortization expense remained consistent in the current period compared to the same period in the prior year as there were no changes to our amortizable base of intangible assets.

Interest Expense, Net

The decrease in interest expense, net in the current period compared to the prior year period was primarily due to a reduction in average debt balance as we paid down $156.0 million of debt under our revolving credit facility and $160.0 million of debt under our term loan facility with proceeds from our IPO and private placement on April 22, 2024. This decrease was partially offset by $1.7 million recorded in interest expense in the current quarter related to a write-off of debt issuance costs associated with our term loan which was partially paid down using proceeds from the Securitization Facility.

Income Tax

The Company’s effective tax rate for the fiscal three months ended September 29, 2024 and October 1, 2023 was 119.9% and 37.2%, respectively. The effective tax rate in the current quarter was impacted by our use of the actual effective tax rate instead of the estimated annual effective tax rate method used in prior interim periods (refer to “Note 12 — Income Taxes” to the condensed consolidated financial statements for further discussion).

NM — Percentage is not meaningful

•Revenue from our U.S. Gas segment totaled $933.3 million, reflecting a decrease of $113.6 million, or 10.9%, compared to the prior year period. This decrease was largely due to a reduction in net volumes under existing customer MSAs stemming primarily from delayed or unfavorable regulatory decisions faced by key customers and timing of bid projects, as the prior year benefited from the commencement of a large project that was substantially complete in the third quarter of 2023. As a percentage of revenue, gross profit decreased to 5.3% in the current period from 9.5% in the prior year period. Profitability was negatively affected by lower margins on bid work as well as higher costs of insurance claims. Additionally, the prior year period reflected higher utilization of fixed costs due to increased volumes on both MSA and bid projects. Revenue from Southwest Gas Corporation totaled $79.2 million for the current period compared to $88.4 million in the prior year period.

•Revenue from our Canadian Gas segment totaled $126.0 million, reflecting a decrease of $16.0 million, or 11.3%, compared to the prior year period. This decrease was primarily due to a reduction in net volumes under existing

MSAs. As a percentage of revenue, gross profit increased to 21.2% in the current period as compared to 15.5% in the prior year period primarily due to favorable changes in mix of work.

•Revenue from our Union Electric segment totaled $499.7 million, reflecting a decrease of $128.3 million, or 20.4%, compared to the prior year period. This decrease was driven by a decline in offshore wind revenue of $71.4 million due to timing of projects, as well as a reduction in net volumes under existing customer MSAs. Storm restoration services revenue for the Union Electric segment was $20.3 million for the current period compared to $24.2 million for the prior year period. As a percentage of revenue, gross profit increased to 7.8% in the current period as compared to 7.0% in the prior year period primarily due to changes in the mix of work and in part from cost savings realized due to restructuring activities which occurred in the prior period.

•Revenue from our Non-Union Electric segment totaled $346.0 million, reflecting a decrease of $34.9 million, or 9.2%, compared to the prior year period. This decrease was primarily driven by a decrease in volumes under existing MSAs, partially offset by an increase in storm restoration services revenue of $7.5 million (which was $66.7 million for the first nine months of 2024 compared to $59.2 million for the same period in 2023). As a percentage of revenue, gross profit decreased to 11.7% in the current period, compared to 13.6% in the same period from the prior year. Profitability was negatively affected by unfavorable changes in mix of work and underutilization of fixed costs stemming from lower work hours.

•Revenue from non-reportable segments decreased due to timing of bid projects, and profitability was negatively impacted by performance issues on certain bid projects.

Selling, General and Administrative Expenses

Selling, general and administrative costs decreased by $5.2 million, or 6.3%, in the current period compared to the same period in the prior year primarily due to lower incentive compensation during the current period and reductions in corporate salary and benefit costs stemming in part from the restructuring activities that have taken place, partially offset by $1.4 million in transaction fees incurred in association with the Company’s Securitization Facility.

Amortization of Intangible Assets

Amortization expense remained consistent between periods as there were no changes to our amortizable base of intangible assets.

Interest Expense, Net

Interest expense, net decreased by $2.4 million between periods due to a reduction in average debt balance, partially offset by higher interest rates on outstanding variable-rate borrowings and $1.7 million recorded in interest expense related to a write-off of debt issuance costs associated with our term loan which was partially paid down using proceeds from the Securitization Facility.

Income Tax

The Company’s effective tax rate for the fiscal nine months ended September 29, 2024 and October 1, 2023 was (3.1)% and 37.3%, respectively. The effective tax rate for the current period was impacted by the disproportionate amount of non-deductible expenses in relation to income before income taxes as well our use of the actual effective tax rate instead of the estimated annual effective tax rate method used in prior interim periods (refer to “Note 12 — Income Taxes” to the condensed consolidated financial statements for further discussion).

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 and Adjusted Net Income, 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 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.

Table of Contents

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 expense, (ii) strategic review costs, (iii) severance costs, (iv) securitization facility transaction fees, (v) CEO transition costs. Adjusted EBITDA Margin is defined as the percentage derived from dividing Adjusted EBITDA by revenue.

Adjusted Net Income is defined as net (loss) income adjusted for (i) strategic review costs, (ii) severance costs, (iii) amortization of intangible assets, (iv) securitization facility transaction fees, (v) CEO transition costs, (vi) loss on debt extinguishment, (vii) non-cash stock-based compensation expense, and (viii) 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.

Using EBITDA as a performance measure has material limitations as compared to net (loss) income, 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 income (loss). When using EBITDA as a performance measure, management compensates for these limitations by comparing EBITDA to net income/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 Adjusted EBITDA, Adjusted EBITDA Margin and Adjusted Net Income: (i) non-cash stock-based compensation expense varies from period to period due to changes in the estimated fair value of performance-based awards, forfeitures and amounts granted; (ii) strategic review and related costs incurred in connection with the separation and stand up of Centuri as its own public company are non-recurring; (iii) severance costs relate to non-recurring restructuring activities, (iv) securitization facility transaction fees represent legal and other professional fees incurred to establish our Securitization Facility, (v) CEO transition costs represent incremental costs incurred to find and hire a replacement CEO, and (vi) loss on debt extinguishment relates to the write-off of debt issuance costs on the Company’s term loan. Because EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin and Adjusted Net Income, as defined, exclude some, but not all, items that affect net (loss) income, such measures may not be comparable to similarly titled measures of other companies. The most comparable GAAP financial measure, net (loss) income, 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 September 29, 2024 and December 31, 2023, cash and cash equivalents were $52.5 million and $33.4 million, respectively. Historically, our primary sources of liquidity have been cash flows from operations and debt financing. As discussed in “Note 1 — Description of Business” to the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q, and “The Offering” within the IPO Prospectus, the Centuri IPO and concurrent private placement have led to changes in our capital structure and sources of liquidity. As part of the Centuri IPO and concurrent private placement which closed on April 22, 2024, we received total net proceeds of $328.0 million in exchange for 16,851,929 shares of our common stock, with $316.0 million of the proceeds being used to pay down our existing debt. 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 a majority of the proceeds to pay down our existing debt. Under the Securitization Facility, certain designated subsidiaries of the Company 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 an indirect wholly owned bankruptcy-remote Special Purpose Entity (“SPE”) of the Company

Table of Contents

created specifically for this purpose. 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 have been sold and derecognized is $125.0 million as of September 29, 2024. As of September 29, 2024, we had no available capacity under the Securitization Facility. 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 at least the next 12 months.

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 Nine Months Ended
(dollars in thousands)	September 29, 2024		October 1, 2023
Net cash provided by operating activities	$	97,232	$	61,809
Net cash used in investing activities	(59,291)		(71,937)
Net cash used in financing activities	(18,747)		(21,487)

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 provided by operating activities for the fiscal nine months ended September 29, 2024 was $97.2 million, compared to $61.8 million for the fiscal nine months ended October 1, 2023, representing an increase in operating cash flows of $35.4 million, primarily due to $125.0 million cash received as part of our Securitization Facility, net of other changes in net working capital and reductions in net income.

Investing Activities

Net cash used in investing activities was $59.3 million in the period ended September 29, 2024 compared to $71.9 million for October 1, 2023, a decrease of $12.6 million.

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 nine months ended September 29, 2024 and October 1, 2023, we had capital expenditures of $66.1 million and $79.6 million, respectively.

These items were partially offset by proceeds from the sale of property and equipment of $6.8 million and $7.7 million for the fiscal nine months ended September 29, 2024 and October 1, 2023, respectively.

Financing Activities

Net cash used in financing activities increased by $2.7 million during the fiscal nine months ended September 29, 2024 compared to the fiscal nine months ended October 1, 2023. Significant changes in financing activities during the current fiscal year include cash inflows from net proceeds from the Centuri IPO and private placement of $328.0 million, and cash flow outflows for the $160.0 million payment on our term loan and $156.0 million payment on our revolving credit facility

Table of Contents

with IPO proceeds, $100.0 million payment on our term loan with proceeds from the Securitization Facility, and our redemption of redeemable noncontrolling interest for $92.8 million.

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 7% and 8% of total revenue, for the fiscal nine months ended September 29, 2024, and October 1, 2023, 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 Facilities

Term Loan and Revolving Credit Facility

We have a senior secured revolving credit and term loan multi-currency facility. The line of credit portion comprises $400 million, and associated amounts borrowed and repaid are available to be re-borrowed. The term loan facility portion provided approximately $1.145 billion in financing as of August 27, 2021. The term loan facility expires on August 27, 2028, and the revolving credit facility expires on August 27, 2026. This multi-currency facility allows us to request loan advances in either Canadian dollars or U.S. dollars. The obligations under the 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 $2.0 billion as of September 29, 2024 and $2.1 billion as of December 31, 2023. During the fiscal nine month period ended September 29, 2024, the maximum amount outstanding on the combined facility was $1.117 billion, at which point $991.4 million was outstanding on the term loan portion of the facility. As of September 29, 2024 and December 31, 2023, $116.4 million and $77.1 million, respectively, was outstanding on the revolving credit facility, in addition to $731.4 million and $994.2 million, respectively, that was outstanding on the term loan portion of the facility. Also as of September 29, 2024 and December 31, 2023, there was approximately $218.4 million and $246.5 million, respectively, net of outstanding letters of credit, of unused capacity under the line of credit. We had $59.8 million and $48.6 million of unused letters of credit available as of September 29, 2024 and December 31, 2023, respectively.

On March 22, 2024, we amended the financial covenants of the revolving credit facility (the “2024 Credit Facility Amendment”) to increase the maximum net leverage ratio. The terms of the amended revolving credit facility required us to maintain certain net leverage ratios, which have since been superseded as noted in the paragraph below.

With the proceeds obtained from the Centuri IPO, we paid down $156.0 million of debt under our revolving credit facility and $160.0 million of debt under our term loan facility. Pursuant to the terms of our 2024 Credit Facility Amendment, completion of the Qualified IPO resulted in a change to the maximum net leverage ratio based on the amount of proceeds received. We are now required to maintain a net leverage ratio of less than a maximum of 5.25 to 1.00 from April 18, 2024 through June 30, 2024, 5.00 to 1.00 from July 1, 2024 through September 29, 2024, and 4.25 to 1.00 from September 30, 2024 through December 29, 2024, and 4.00 to 1.00 thereafter.

We made an additional prepayment on our term loan debt in September 2024 using $100.0 million of the proceeds from our Securitization Facility.

As a result of the prepayments on our term loan and revolving credit facility, our contractually obligated principal payments on long-term debt over are now as follows (dollars in thousands):


Remainder of 2024	$	8,418
2025	29,441
2026	144,911
2027	7,263
2028	731,375

Total	$	921,408

Table of Contents

Based on the weighted average interest rate on the term loan facility of 7.87% as of September 29, 2024, the prepayment of our term loan with proceeds from the IPO reduces our contractually obligated interest payments on our term loan by approximately $3.1 million throughout the remainder of 2024, $22.0 million between 2025 and 2026, and $15.8 million between 2027 and 2028.

Equipment Term Loans

We currently have seven equipment term loans with initial amounts totaling approximately $170 million, with certain owned equipment used as collateral. The loans are serviced in U.S. dollars. These term loans have prepayment penalties for the first three years of the agreements. We did not incur any material prepayment penalties on any of our equipment loans during the first fiscal nine months of 2024 or 2023.

Recently Issued Accounting Pronouncements

Refer to “Note 2 — Basis of Presentation and Summary of Significant Accounting Policies” to our condensed consolidated financial statements for a discussion of recent accounting standards and pronouncements.

Critical Accounting Policies and Estimates

This discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these condensed consolidated financial statements requires the use of estimates and assumptions. A summary of our critical accounting policies and estimates is included in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in the IPO Prospectus. We are required to make estimates and judgments in the preparation of our condensed consolidated financial statements that affect the reported amounts of assets and liabilities, revenue and expenses and related disclosures. We continually review these estimates and their underlying assumptions to ensure they are appropriate for the circumstances. Changes in the estimates and assumptions we use could have a material impact on our financial results. During the fiscal nine months ended September 29, 2024, there were no material changes in our critical accounting estimates or policies.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There were no material changes to our quantitative and qualitative disclosures about market risk during the fiscal nine months ended September 29, 2024. Refer to “Quantitative and Qualitative Disclosures about Market Risk” within the IPO Prospectus for information on financial market risk related to changes in interest rates and currency exchange rates. Our primary exposure to market risk relates to unfavorable changes in interest rates and currency exchange rates.

For a discussion of our concentration of credit risk, refer to “Note 15 — Commitments and Contingencies” to our condensed consolidated financial statements.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

At the end of the period covered by this Quarterly Report on Form 10-Q, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 14d-15(e) under the Exchange Act). Our disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure. Our Chief Executive Officer and Chief Financial Officer reviewed and participated in this evaluation, and both concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective.

Changes in Internal Control

Table of Contents

There have been no changes in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the third quarter of 2024 that have materially affected, or are likely to materially affect the Company’s internal control over financial reporting.

Part II - Other Information

Item 1. Legal Proceedings

For discussion regarding legal proceedings, please refer to “Note 15 — Commitments and Contingencies” in the accompanying notes to our condensed consolidated financial statements.

Item 1A. Risk Factors

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

None.

Item 3. Defaults Upon Senior Securities

None.

Item 4. Mine Safety Disclosures

Not applicable.

Item 5. Other Information

Rule 10b5-1 Trading Arrangements

During the fiscal three months ended September 29, 2024, none of our directors or officers adopted or terminated a “Rule 10b5-1 trading arrangement” or a “non-Rule 10b5-1 trading arrangement” (in each case, as defined in Item 408 of Regulation S-K).

Description of Business	Sep. 29, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business Organization Structure Centuri Holdings, Inc. (“Holdings” and, collectively with the Operating Company (as defined below) and its consolidated subsidiaries, the “Company” or “Centuri”) was formed as a Delaware corporation in June 2023. Holdings was formed for the purpose of completing an initial public offering and facilitating the separation of Centuri Group, Inc. (the “Operating Company”) from Southwest Gas Holdings, Inc. (“Southwest Gas Holdings”) in order to carry on the business of the Operating Company. From formation until April 13, 2024, Southwest Gas Holdings owned 1,000 shares of Holdings common stock, representing 100% of the issued and outstanding shares of common stock of Holdings. The Operating Company was formed as a wholly owned subsidiary of Southwest Gas Holdings under the laws of the state of Nevada in October 2014 to consolidate and oversee the operations of several utility infrastructure services companies operating throughout North America. On April 13, 2024, Holdings issued 71,664,592 shares of common stock to Southwest Gas Holdings as consideration for the transfer of assets and assumption of liabilities of the Operating Company (“the Separation”). Following the completion of the Separation, the Operating Company became a wholly owned subsidiary of Holdings, and all of Holdings’ operations are conducted through the Operating Company. Prior to its acquisition of the Operating Company as part of the Separation, Holdings had nominal assets, liabilities, and operations. As Holdings and the Operating Company were both wholly owned by Southwest Gas Holdings as of April 13, 2024, Holdings’ acquisition of the Operating Company as part of the Separation is treated as a reorganization of entities under common control that results in a change in reporting entity. The Operating Company has been determined to be the predecessor for accounting purposes and, accordingly, the condensed consolidated financial statements for periods prior to the combination of Holdings and the Operating Company on April 13, 2024 have been adjusted to combine the previously separate entities for presentation purposes. Amounts for the period from January 2, 2023 through October 1, 2023 and from January 1, 2024 through April 12, 2024 presented in the condensed consolidated financial statements and condensed notes to the financial statements herein represent the historical operations of the Operating Company. The amounts as of September 29, 2024 and for the period from April 13, 2024 reflect the consolidated operations of the Company. For calculation of earnings per share, shares outstanding for all periods prior to April 13, 2024 have been retrospectively adjusted to 71,665,592 to reflect the shares of the Company owned by Southwest Gas Holdings immediately after the combination on April 13, 2024 which resulted in the change in reporting entity. Outstanding shares presented on the Company’s condensed consolidated balance sheet and statement of changes in equity for historical periods have been presented as 1,000 to reflect the shares of Holdings that existed at the formation of Holdings. Description of Operations The Company is a pure-play North American utility infrastructure services company that 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 maintenance, retrofitting and installation of electric and natural gas distribution networks, building capacity to meet current and future demands and preparing systems for the expected energy transition. The Company operates through a family of integrated companies working together across different geographies to establish solid customer relationships and a strong reputation for a wide range of capabilities. Initial Public Offering On April 17, 2024, the registration statement related to the initial public offering of Centuri’s common stock was declared effective, and Centuri’s common stock began trading on the New York Stock Exchange under the ticker “CTRI” (the “Centuri IPO”) on April 18, 2024. On April 22, 2024, the Centuri IPO was completed through the sale of 14,260,000 shares of Holdings common stock, par value $0.01 per share, including the underwriters’ full exercise of their option to purchase 1,860,000 shares to cover over-allotments, at an initial public offering price of $21.00 per share. On the same day, Icahn Partners and Icahn Partners Master Fund LP, investment entities affiliated with Carl C. Icahn, purchased 2,591,929 shares of Centuri’s common stock in a concurrent private placement at a price per share equal to the IPO price, for gross proceeds of approximately $54.4 million. The total final net proceeds to Centuri from the Centuri IPO and the concurrent private placement, after deducting underwriting discounts and commissions of $18.0 million and offering expenses payable by Centuri of $8.0 million, were $328.0 million. Offering expenses represent costs that were determined to be directly attributable to the Centuri IPO, and are recorded as a reduction in additional paid-in capital on the Company’s condensed consolidated balance sheet. As of the closing of the Centuri IPO, Southwest Gas Holdings owned 71,665,592 shares of Centuri common stock, or approximately 81% of the total outstanding shares of Centuri.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies 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 for the fiscal year ended December 31, 2023, as included in the Company’s final IPO prospectus (the “IPO Prospectus”) filed on April 18, 2024 with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended relating to Centuri’s Registration Statement on Form S-1. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations, comprehensive income and cash flows with respect to the interim condensed consolidated financial statements have been included. The results of operations and comprehensive income 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. As of and prior to December 31, 2023, the Company reported its results under two reportable segments. In January 2024, the Company appointed a new Chief Executive Officer, who was determined by Centuri to be the Company’s chief operating decision maker (“CODM”). Following this appointment, the Company underwent an internal personnel reorganization, causing the Company to re-evaluate its reportable segments based on the information reviewed by the new CODM. Effective July 31, 2024, the Company appointed a new interim Chief Executive Officer who currently acts as the Company’s CODM. However, there have been no changes in the information reviewed by the CODM. See “Note 4 — Segment Information” for additional details. 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 in the Company’s condensed consolidated financial statements relate to fiscal months rather than calendar months. The fiscal nine month period ended September 29, 2024 and October 1, 2023 each had 39 weeks, and the third fiscal quarters of 2024 and 2023 each had 13 weeks. Cloud Computing Arrangements The Company capitalizes certain implementation costs incurred in the application development stage of projects related to its cloud computing arrangements (“CCA”) that are service contracts. Capitalized CCA implementation costs are recognized in other assets in the condensed consolidated balance sheets and expensed on a straight-line basis over the fixed, noncancellable term of the associated hosting arrangement plus any reasonably certain renewal periods. As of September 29, 2024, the net carrying amounts of the Company’s CCA implementation costs were $27.6 million. Amortization of CCA-related assets is classified as a cash operating expense (i.e., not included in amortization or depreciation in the Company’s condensed consolidated financial statements). CCA implementation expenditures are included within cash flows from operating activities in the condensed consolidated statement of cash flows. Recent Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The update improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This update is effective beginning with the Company’s 2024 fiscal year annual reporting period, and will be effective for interim reporting periods in the Company’s fiscal 2025, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this update will have on its disclosures. 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 is effective beginning with the Company’s 2025 fiscal year annual reporting period, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this update will have on its disclosures. In March 2024, the SEC issued the final rules under SEC Release No. 33-11275, “The Enhancement and Standardization of Climate-Related Disclosures for Investors.” In April 2024, the SEC voluntarily stayed the new rules as a result of pending legal challenges. Absent the stay and the result of pending legal challenges, these rules will require registrants to disclose certain climate-related information, including Scope 1 and Scope 2 greenhouse gas emissions and other climate-related topics, in registration statements and annual reports, when material. Disclosure requirements, absent the results of pending legal challenges, will begin phasing in with the annual reporting for the fiscal year ending 2027 based on Centuri’s current status as a non-accelerated filer. The Company is currently evaluating the impact the rules will have on its disclosures.

Accounts Receivable Securitization Facility	9 Months Ended
Accounts Receivable Securitization Facility	Sep. 29, 2024
Transfers and Servicing [Abstract]
Accounts Receivable Securitization Facility	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 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 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 and its related subsidiaries have no continuing involvement in the transferred accounts receivable, other than collection and administrative responsibilities, and, once sold, the accounts receivable are no longer available to satisfy the creditors or the related subsidiaries. The Company has not recorded any servicing asset or liability related to this continuing involvement as the Company has determined it is compensated adequately for its servicing role. 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. In addition, Centuri Group, Inc. has agreed to guarantee the performance of the indirect wholly-owned subsidiaries of the Company and itself as the servicer of their respective obligations under the documentation for the Securitization Facility. Centuri Group, Inc. is not guaranteeing the collectibility of any assets transferred in the Securitization Facility or the creditworthiness of the related obligors. The Securitization Facility is subject to yield charges based upon a rate as specified in the documentation for the Securitization Facility. These yield charges are recorded in interest expense, net on the Company’s condensed consolidated statement of operations, and were not material for the fiscal three or nine months ended September 29, 2024. The Company may incur a recourse obligation in limited circumstances, but the Company has determined this liability is not material. The total outstanding balance of accounts receivable that had been sold and derecognized was $125.0 million as of September 29, 2024. Additionally, the SPE owned accounts receivable and contract assets of $60.6 million and $115.5 million, respectively, as of September 29, 2024, which were not sold to PNC but were pledged as collateral. These balances are primarily included in accounts receivable, net and contract assets (and the accompanying related party captions) in the Company’s condensed consolidated balance sheet, with certain non-current balances being included in other assets. For the nine months ended September 29, 2024, the Company received $125.0 million in cash proceeds from the Securitization Facility, which is recorded in operating cash flows on the condensed consolidated statement of cash flows, and had no repayments on the Securitization Facility. As of September 29, 2024, the Company had no available capacity under the Securitization Facility.

Income Taxes	9 Months Ended
Income Taxes	Sep. 29, 2024
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Historically, including in the first and second quarters of 2024, the Company has calculated the provision for income taxes for interim periods by applying an estimate of the annual effective tax rate for the full year to “ordinary” income or loss. However, because fluctuations in estimated ordinary income can result in significant changes in the estimated annual effective tax rate, the Company determined that this method does not provide a reliable estimate for the fiscal nine months ended September 29, 2024. As such, the Company calculates its interim income tax expense for the fiscal nine months ended September 29, 2024 on a discrete basis, consistent with the guidance in ASC 740-270, Income Taxes - Interim Reporting. The Company’s effective tax rate for the fiscal three months ended September 29, 2024 and October 1, 2023 was 119.9% and 37.2%, respectively, and for the fiscal nine months ended September 29, 2024 and October 1, 2023 was (3.1)% and 37.3%, respectively. The effective tax rate in the current year periods was impacted by the Company’s use of the actual effective tax rate instead of the estimated annual effective tax rate method used in prior interim periods, as well as the disproportionate amount of non-deductible expenses in relation to income before income taxes. 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. 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. As of September 29, 2024 and December 31, 2023, the total amount of unrecognized tax benefits relating to uncertain tax positions was $0.5 million. As of September 29, 2024, with certain exceptions, the Company is no longer subject to U.S. federal, state, local, or Canadian examinations for years before fiscal 2018. As discussed in “Note 14 — Related Parties”, the Company is a party to a tax matters agreement with Southwest Gas Holdings. The agreement outlines the method in which the Company calculates its income tax liability and the manner in which it either reimburses Southwest Gas Holdings for taxes owed or is reimbursed for credits and net operating losses used.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	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. 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 intends to have the case reviewed by the Circuit Court of Cook County Illinois. The Company intends to vigorously pursue this matter, however, the Company cannot accurately predict the ultimate outcome. With the ultimate timing and conclusion unknown, the Company has not recognized any incremental amount in income to the extent NPL’s claims for relief are awarded in the Company’s favor. Further, to the extent the Company is not successful in collecting the withheld receivables, this matter could result in an additional significant loss. The Company can provide no assurance as to whether or when there will be material developments in these matters. 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 the 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 clauses that become effective upon a change in control of the Company. Upon the 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 responsibility. Concentration of Credit Risk The Company provides full-service utility 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 10%. No customers accounted for more than 10% of revenue during the fiscal three or nine month periods ended September 29, 2024 or October 1, 2023. No customer had a combined accounts receivable and contract asset balance above 10% of the consolidated accounts receivable and contract assets balance. One Union Electric customer had a combined accounts receivable and contract asset balance of $84.3 million as of December 31, 2023, which was approximately 14% of the consolidated balance of these accounts. The Company primarily uses three financial banking institutions. The Company’s cash on deposit with these financial institutions exceeded the federal insurability limits as of September 29, 2024. 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 or provide services 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 September 29, 2024, 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 September 29, 2024, the estimated total amount of outstanding performance and payment bonds was approximately $637.3 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 $289.6 million as of September 29, 2024. 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.

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
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 for the fiscal year ended December 31, 2023, as included in the Company’s final IPO prospectus (the “IPO Prospectus”) filed on April 18, 2024 with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended relating to Centuri’s Registration Statement on Form S-1. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations, comprehensive income and cash flows with respect to the interim condensed consolidated financial statements have been included. The results of operations and comprehensive income 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.
Segment Reporting	As of and prior to December 31, 2023, the Company reported its results under two reportable segments. In January 2024, the Company appointed a new Chief Executive Officer, who was determined by Centuri to be the Company’s chief operating decision maker (“CODM”). Following this appointment, the Company underwent an internal personnel reorganization, causing the Company to re-evaluate its reportable segments based on the information reviewed by the new CODM. Effective July 31, 2024, the Company appointed a new interim Chief Executive Officer who currently acts as the Company’s CODM. However, there have been no changes in the information reviewed by the CODM.
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 months in the Company’s condensed consolidated financial statements relate to fiscal months rather than calendar months. The fiscal nine month period ended September 29, 2024 and October 1, 2023 each had 39 weeks, and the third fiscal quarters of 2024 and 2023 each had 13 weeks.
Cloud Computing Arrangements	The Company capitalizes certain implementation costs incurred in the application development stage of projects related to its cloud computing arrangements (“CCA”) that are service contracts. Capitalized CCA implementation costs are recognized in other assets in the condensed consolidated balance sheets and expensed on a straight-line basis over the fixed, noncancellable term of the associated hosting arrangement plus any reasonably certain renewal periods.
Recent Accounting Pronouncements	In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The update improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This update is effective beginning with the Company’s 2024 fiscal year annual reporting period, and will be effective for interim reporting periods in the Company’s fiscal 2025, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this update will have on its disclosures. 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 is effective beginning with the Company’s 2025 fiscal year annual reporting period, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this update will have on its disclosures. In March 2024, the SEC issued the final rules under SEC Release No. 33-11275, “The Enhancement and Standardization of Climate-Related Disclosures for Investors.” In April 2024, the SEC voluntarily stayed the new rules as a result of pending legal challenges. Absent the stay and the result of pending legal challenges, these rules will require registrants to disclose certain climate-related information, including Scope 1 and Scope 2 greenhouse gas emissions and other climate-related topics, in registration statements and annual reports, when material. Disclosure requirements, absent the results of pending legal challenges, will begin phasing in with the annual reporting for the fiscal year ending 2027 based on Centuri’s current status as a non-accelerated filer. The Company is currently evaluating the impact the rules will have on its disclosures.
