The accompanying unaudited condensed consolidated financial statements of the Company and its subsidiaries, all of which are wholly-owned, have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements and should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in this report and the Company’s audited financial statements included in the Company’s Annual Report on Form 10-K for fiscal 2022, filed with the SEC on March 4, 2022. In the opinion of management, all adjustments considered necessary for a fair statement of the results for the interim periods presented have been included.

Operating results for the interim period are not necessarily indicative of the results expected for any subsequent interim or annual period. Segment Information. The Company operates in one reportable segment. Its services are provided by its operating segments on a decentralized basis. Each operating segment consists of a subsidiary (or in certain instances, the combination of two or more subsidiaries), the results of which are regularly reviewed by the Company’s Chief Executive Officer, the chief operating decision maker. All of the Company’s operating segments have been aggregated into one reportable segment based on their similar economic characteristics, nature of services and production processes, type of customers, and service distribution methods.

Earnings Per Share [Abstract]
Computation of Earnings Per Common Share	Computation of Earnings per Common Share The following table sets forth the computation of basic and diluted earnings per common share (dollars in thousands, except per share amounts): For the Three Months Ended For the Nine Months Ended October 29, 2022 October 30, 2021 October 29, 2022 October 30, 2021 Net income available to common stockholders (numerator) $ 54,012 $ 28,717 $ 117,404 $ 47,780 Weighted-average number of common shares (denominator) 29,524,516 30,172,254 29,561,172 30,426,337 Basic earnings per common share $ 1.83 $ 0.95 $ 3.97 $ 1.57 Weighted-average number of common shares 29,524,516 30,172,254 29,561,172 30,426,337 Potential shares of common stock arising from stock options, and unvested restricted share units 454,279 442,452 446,085 502,553 Total shares-diluted (denominator) 29,978,795 30,614,706 30,007,257 30,928,890 Diluted earnings per common share $ 1.80 $ 0.94 $ 3.91 $ 1.54 Anti-dilutive weighted shares excluded from the calculation of earnings per common share: Stock-based awards 93,147 218,525 98,863 89,765 0.75% convertible senior notes due 2021 (1) (2) — 297,367 — 500,017 Warrants (1) (2) — 601,349 — 601,349 Total 93,147 1,117,241 98,863 1,191,131 (1) The Company used the treasury stock method for calculating any potential dilutive impact on earnings per common share if our average stock price for the period exceeded the $96.89 per share conversion price. There was no dilutive impact on earnings per common share during any of the periods presented as our average stock price did not exceed the per share conversion price and the 2021 Convertible Notes (as defined in Note 13) matured on September 15, 2021. The warrants associated with our 2021 Convertible Notes would have had a dilutive impact on earnings per common share if our average stock price for the period had exceeded the $130.43 per share warrant strike price. As our average stock price did not exceed the strike price for the warrants for any periods presented, the underlying common shares were anti-dilutive as reflected in the table above. The warrants were scheduled to expire on a series of dates concluding on May 9, 2022. During the fourth quarter of fiscal 2022, we purchased the remaining warrants for $0.7 million and there are no additional warrants outstanding. (2) In connection with the offering of the 2021 Convertible Notes, we entered into convertible note hedge transactions with counterparties for the purpose of reducing the potential dilution to common stockholders from the conversion of the 2021 Convertible Notes and offsetting any potential cash payments in excess of the principal amount of the 2021 Convertible Notes. Prior to conversion, the convertible note hedge was not included for purposes of the calculation of earnings per common share as its effect would be anti-dilutive. Upon any conversion, the convertible note hedge was expected to offset the dilutive effect of the 2021 Convertible Notes when the average stock price for the period was above $96.89 per share. The 2021 Convertible Notes matured on September 15, 2021. The convertible note hedge transactions expired on September 13, 2021. See Note 13, Debt , for additional information related to our 2021 Convertible Notes, warrant transactions, and hedge transactions.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill There was no change in the carrying amount of goodwill during the nine months ended October 29, 2022. The g oodwill balance consisted of the following (dollars in thousands): October 29, 2022 January 29, 2022 Goodwill, gross $ 521,516 $ 521,516 Accumulated impairment losses (249,031) (249,031) Total $ 272,485 $ 272,485 The Company’s goodwill resides in multiple reporting units and primarily consists of expected synergies, together with the expansion of the Company’s geographic presence and strengthening of its customer base from acquisitions. Goodwill and other indefinite-lived intangible assets are assessed annually for impairment, or more frequently if events occur that would indicate a potential reduction in the fair value of a reporting unit below its carrying value. The profitability of individual reporting units may suffer periodically due to downturns in customer demand, increased costs of providing services, and the level of overall economic activity. The Company’s customers may reduce capital expenditures and defer or cancel pending projects due to changes in technology, a slowing or uncertain economy, merger or acquisition activity, a decision to allocate resources to other areas of their business, or other reasons. The profitability of reporting units may also suffer if actual costs of providing services exceed the costs anticipated when the Company enters into contracts. Additionally, adverse conditions in the economy and future volatility in the equity and credit markets could impact the valuation of the Company’s reporting units. The cyclical nature of the Company’s business, the high level of competition existing within its industry, and the concentration of its revenues from a limited number of customers may also cause results to vary. These factors may affect individual reporting units disproportionately, relative to the Company as a whole. As a result, the performance of one or more of the reporting units could decline, resulting in an impairment of goodwill or intangible assets. The Company performs its annual impairment assessment as of the first day of the fourth fiscal quarter of each fiscal year. As a result of the Company’s fiscal 2022 period assessment, the Company determined that the fair values of each of the reporting units and the indefinite-lived intangible asset were in excess of their carrying values and no impairment had occurred. As of October 29, 2022, the Company continues to believe the remaining goodwill and the indefinite-lived intangible asset are recoverable for all of its reporting units . Intangible Assets Our intangible assets consisted of the following (dollars in thousands): October 29, 2022 January 29, 2022 Weighted Average Remaining Useful Lives (Years) Gross Carrying Amount Accumulated Amortization Intangible Assets, Net Gross Carrying Amount Accumulated Amortization Intangible Assets, Net Customer relationships 7.8 $ 312,017 $ 227,407 $ 84,610 $ 312,017 $ 215,806 $ 96,211 Trade names, finite 7.8 9,250 8,422 828 9,250 8,329 921 Trade name, indefinite — 4,700 — 4,700 4,700 — 4,700 $ 325,967 $ 235,829 $ 90,138 $ 325,967 $ 224,135 $ 101,832 Amortization of our customer relationship intangibles is recognized on an accelerated basis as a function of the expected economic benefit. Amortization of our other finite-lived intangibles is recognized on a straight-line basis over the estimated useful life. Amortization expense for finite-lived intangible assets was $3.9 million and $4.1 million for the three months ended October 29, 2022 and October 30, 2021, respectively, and $11.7 million and $13.5 million for the nine months ended October 29, 2022 and October 30, 2021, respectively. As of October 29, 2022, we believe that the carrying amounts of our intangible assets are recoverable. However, if adverse events were to occur or circumstances were to change indicating that the carrying amount of such assets may not be fully recoverable, the assets would be reviewed for impairment.

Accrued Insurance Claims	Oct. 29, 2022
Accrued Insurance Claims [Abstract]
Accrued Insurance Claims	Accrued Insurance Claims Within our insurance program, we retain the risk of loss on a per occurrence basis in varying amounts depending on the type of claim and the terms of the applicable insurance coverage. Additionally, we retain the risk of loss, up to certain annual aggregate stop loss limits, for claims covered by our automobile liability, general liability (including claims relating to underground facility locating services), workers’ compensation, and employee group health. Losses for covered claims beyond our retained risk of loss are paid or reimbursed by our insurance carriers up to our coverage limits. For fiscal 2022, with regard to workers’ compensation losses, we retained the risk of loss up to $1.0 million on a per occurrence basis. This retention amount is applicable to all of the states in which we operate, except with respect to workers’ compensation insurance in two states in which we participate in state-sponsored insurance funds. With regard to automobile liability and general liability losses for fiscal 2022, we retained the risk of loss up to $1.0 million on a per-occurrence basis for the first $5.0 million of insurance coverage. We also retained the risk of loss for automobile and general liability for the next $5.0 million on a per-occurrence basis with aggregate loss limits of $11.5 million within this layer of retention. In addition, we retained $10.0 million risk of loss on a per occurrence basis for losses above $30.0 million. For fiscal 2023, with regard to workers’ compensation losses, our retention of risk remains the same as fiscal 2022. With regard to automobile liability and general liability losses, our retention of risk remains the same as fiscal 2022, with the exception that we retained an additional $5.0 million risk of loss on a per occurrence basis for losses above $10.0 million, if any. We are party to a stop-loss agreement for losses under our employee group health plan. For the calendar year 2022, we retain the risk of loss on an annual basis, up to the first $600,000 of claims per participant. Amounts for total accrued insurance claims and insurance recoveries/receivables are as follows (dollars in thousands): October 29, 2022 January 29, 2022 Accrued insurance claims - current $ 41,594 $ 36,805 Accrued insurance claims - non-current 48,719 48,238 Accrued insurance claims $ 90,313 $ 85,043 Insurance recoveries/receivables: Current (included in Other current assets) $ 69 $ 756 Non-current (included in Other assets) 3,324 3,687 Insurance recoveries/receivables $ 3,393 $ 4,443 Insurance recoveries/receivables represent the amount of accrued insurance claims that are covered by insurance as the amounts exceed the Company’s loss retention. During the nine months ended October 29, 2022, total insurance recoveries/receivables decreased approximately $1.1 million primarily due to the settlement of claims that exceeded our loss retention. Accrued insurance claims decreased by a corresponding amount.

The Credit Agreement includes a $200.0 million sublimit for the issuance of letters of credit and a $50.0 million sublimit for swingline loans. As part of the amendment, the maturity of the Credit Agreement was extended to April 1, 2026. The following table summarizes the net carrying value of the term loan as of October 29, 2022 and January 29, 2022 (dollars in thousands): October 29, 2022 January 29, 2022 Principal amount of term loan $ 336,875 $ 350,000 Less: Debt issuance costs (2,060) (2,562) Net carrying amount of term loan $ 334,815 $ 347,438 Subject to certain conditions, the Credit Agreement provides us with the ability to enter into one or more incremental facilities either by increasing the revolving commitments under the Credit Agreement and/or by establishing one or more additional term loans, up to the sum of (i) $350.0 million and (ii) an aggregate amount such that, after giving effect to such incremental facilities on a pro forma basis (assuming that the amount of the incremental commitments are fully drawn and funded), the consolidated senior secured net leverage ratio does not exceed 2.25 to 1.00. The consolidated senior secured net leverage ratio is the ratio of our consolidated senior secured indebtedness reduced by unrestricted cash and equivalents in excess of $25.0 million to our trailing twelve-month consolidated earnings before interest, taxes, depreciation, and amortization, as defined by the Credit Agreement (“EBITDA”). Borrowings under the Credit Agreement are guaranteed by substantially all of our domestic subsidiaries and secured by 100% of the equity interests of our direct and indirect domestic subsidiaries and 65% of the voting equity interests and 100% of the non-voting interests of our first-tier foreign subsidiaries (subject to customary exceptions). Under the Credit Agreement, borrowings bear interest at the rates described below based upon our consolidated net leverage ratio, which is the ratio of our consolidated total funded debt reduced by unrestricted cash and equivalents in excess of $25.0 million to our trailing twelve-month consolidated EBITDA, as defined by the Credit Agreement. In addition, we incur certain fees for unused balances and letters of credit at the rates described below, also based upon our consolidated net leverage ratio. Borrowings - Eurodollar Rate Loans 1.25% - 2.00% plus LIBOR (1) Borrowings - Base Rate Loans 0.25% - 1.00% plus Base rate (2) Unused Revolver Commitment 0.20% - 0.40% Standby Letters of Credit 1.25% - 2.00% Commercial Letters of Credit 0.625% -1.000% (1) To address the transition in financial markets away from LIBOR, the Credit Agreement includes provisions related to the replacement of LIBOR with a LIBOR Successor Rate (as defined in the Credit Agreement), which may be a rate based on the secured overnight financing rate published by the Federal Reserve Bank of New York. (2) Base rate is described in our Credit Agreement as the highest of (i) the Federal Funds Rate plus 0.50%, (ii) the administrative agent’s prime rate, and (iii) the Eurodollar rate plus 1.00% and, if such rate is less than zero, such rate shall be deemed zero. Standby letters of credit of approximately $47.5 million and $46.3 million, issued as part of our insurance program, were outstanding under the Credit Agreement as of October 29, 2022 and January 29, 2022, respectively. The weighted average interest rates and fees for balances under our Credit Agreement as of October 29, 2022 and January 29, 2022 were as follows: Weighted Average Rate End of Period October 29, 2022 January 29, 2022 Borrowings - Term loan facility 5.16% 1.86% Borrowings - Revolving facility (1) —% —% Standby Letters of Credit 1.75% 1.63% Unused Revolver Commitment 0.35% 0.30% (1) There were no outstanding borrowings under our revolving facility as of October 29, 2022 and January 29, 2022. The Credit Agreement contains a financial covenant that requires us to maintain a consolidated net leverage ratio of not greater than 3.50 to 1.00, as measured at the end of each fiscal quarter, and provides for certain increases to this ratio in connection with permitted acquisitions. The agreement also contains a financial covenant that requires us to maintain a consolidated interest coverage ratio, which is the ratio of our trailing twelve-month consolidated EBITDA to our consolidated interest expense, each as defined by the Credit Agreement, of not less than 3.00 to 1.00, as measured at the end of each fiscal quarter. At October 29, 2022 and January 29, 2022, we were in compliance with the financial covenants of our Credit Agreement and had borrowing availability under the revolving facility of $419.2 million and $326.3 million, respectively, as determined by the most restrictive covenant. For calculation purposes, applicable cash on hand is netted against the funded debt amount as permitted in the Credit Agreement. 4.50% Senior Notes Due 2029 On April 1, 2021, we issued $500.0 million aggregate principal amount of 4.50% senior notes due 2029 (the “2029 Notes”). The 2029 Notes are guaranteed on a senior unsecured basis, jointly and severally, by all of our domestic subsidiaries that guarantee the Credit Agreement. The indenture governing the 2029 Notes contains certain covenants that limit, among other things, our ability and the ability of certain of our subsidiaries to (i) incur additional debt and issue certain preferred stock, (ii) pay certain dividends on, repurchase, or make distributions in respect of, our and our Subsidiaries’ capital stock or make other payments restricted by the indenture, (iii) enter into agreements that place limitations on distributions made from certain of our subsidiaries, (iv) guarantee certain debt, (v) make certain investments, (vi) sell or exchange certain assets, (vii) enter into transactions with affiliates, (viii) create certain liens, and (ix) consolidate, merge or transfer all or substantially all of our or our Subsidiaries’ assets. These covenants are subject to a number of exceptions, limitations and qualifications as set forth in the indenture governing the 2029 Notes. The following table summarizes the net carrying value of the 2029 Notes as of October 29, 2022 and January 29, 2022 (dollars in thousands): October 29, 2022 January 29, 2022 Principal amount of 2029 Notes $ 500,000 $ 500,000 Less: Debt issuance costs (5,965) (6,687) Net carrying amount of 2029 Notes $ 494,035 $ 493,313 The following table summarizes the fair value of the 2029 Notes, net of debt issuance costs. The fair value of the 2029 Notes is based on the closing trading price per $100 of the 2029 Notes as of the last day of trading (Level 2), which was $87.25 and $97.50 as of October 29, 2022 and January 29, 2022, respectively (dollars in thousands): October 29, 2022 January 29, 2022 Fair value of principal amount of 2029 Notes $ 436,250 $ 487,500 Less: Debt issuance costs (5,965) (6,687) Fair value of 2029 Notes $ 430,285 $ 480,813 0.75% Convertible Senior Notes Due 2021 On September 15, 2015, we issued 0.75% convertible senior notes in a private placement in the principal amount of $485.0 million (the “2021 Convertible Notes”). The 2021 Convertible Notes, governed by the terms of an indenture between the Company and a bank trustee, were unsecured obligations and did not contain any financial covenants or restrictions on the payments of dividends, the incurrence of indebtedness, or the issuance or repurchase of securities by the Company. The 2021 Convertible Notes bore interest at a rate of 0.75% per year, payable in cash semiannually in March and September, and matured on September 15, 2021. On the maturity date the outstanding balance of $58.3 million under the 2021 Convertible Notes was repaid in full and no 2021 Convertible Notes were converted prior to maturity. In connection with the offering of the 2021 Convertible Notes, we entered into convertible note hedge transactions with counterparties for the purpose of reducing the potential dilution to common stockholders from the conversion of the 2021 Convertible Notes and offsetting any potential cash payments in excess of the principal amount of the 2021 Convertible Notes. We also entered into separately negotiated warrant transactions with the same counterparties whereby we sold warrants to purchase shares of our common stock at a price of $130.43 per share. The convertible note hedge transactions expired in September 2021. In addition, we unwound the remaining warrants during the fourth quarter of fiscal 2022 and, as a result, there are no additional warrants outstanding. For further information, see Note 13 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for fiscal 2022.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our interim income tax provisions are based on the effective income tax rate expected to be applicable for the full fiscal year, adjusted for specific items that are required to be recognized in the period in which they occur. Deferred tax assets and liabilities are based on the enacted tax rate that will apply in future periods when such assets and liabilities are expected to be settled or realized. Our effective income tax rate was 21.9% and 17.7% for the three months ended October 29, 2022 and October 30, 2021, respectively, and 20.8% and 17.2% for the nine months ended October 29, 2022 and October 30, 2021, respectively. The effective tax rate differs from the statutory rate primarily due to tax credits recognized, the impact of the vesting and exercise of share-based awards, and the difference in income tax rates from state to state where work was performed. The three and nine months ended October 29, 2022, includes approximately $1.8 million and $3.4 million, respectively, for tax benefits for credits related to tax filings for prior years. Additionally, the three and nine months ended October 30, 2021, includes approximately $3.0 million for incremental tax benefits for credits related to tax filings for prior periods. Other fluctuations in our effective income tax rate from the statutory rate each period are mainly attributable to changes in unrecognized tax benefits, tax law changes, and variances in non-deductible and non-taxable items. During the first quarter of fiscal 2023, we were notified by the Internal Revenue Service that our federal income tax return for fiscal 2016 was selected for examination due to the net operating loss carryback claim filed in fiscal 2021. In addition, fiscal year 2020 was selected for examination in the second quarter of fiscal 2022. We believe our provision for income taxes is adequate; however, any assessment may affect our results of operations and cash flows.

Capital Stock	Capital Stock Repurchases of Common Stock. On March 2, 2022 the Company announced that its Board of Directors had authorized a new $150 million program to repurchase shares of the Company’s outstanding common stock through August 2023 in open market or private transactions. The new authorization replaces the remaining $43.9 million that was available under the prior authorization. During the three months ended October 29, 2022, the Company did not repurchase any shares of its own common stock. As of October 29, 2022, $121.5 million of the authorization was available for repurchases. Upon cancellation of shares repurchased or withheld for tax withholdings, the excess over par value is recorded as a reduction of additional paid-in capital until the balance is reduced to zero, with any additional excess recorded as a reduction of retained earnings. During the nine months ended October 29, 2022, $27.5 million was charged to retained earnings related to shares canceled during the period.

Stock-Based Awards

Stock-Based Awards	Oct. 29, 2022
Share-Based Payment Arrangement [Abstract]
Stock-Based Awards	Stock-Based Awards We have certain stock-based compensation plans under which we grant stock-based awards, including common stock, stock options, time-based restricted share units (“RSUs”), and performance-based restricted share units (“Performance RSUs”) to attract, retain, and reward talented employees, officers, and directors, and to align stockholder and employee interests. Compensation expense for stock-based awards is based on fair value at the measurement date. This expense fluctuates over time as a function of the duration of vesting periods of the stock-based awards and the Company’s performance, as measured by criteria set forth in performance-based awards. Stock-based compensation expense is included in general and administrative expenses in the condensed consolidated statements of operations and the amount of expense ultimately recognized depends on the quantity of awards that actually vest. Accordingly, stock-based compensation expense may vary from period to period. The performance criteria for the Company’s performance-based equity awards utilize the Company’s operating earnings (adjusted for certain amounts) as a percentage of contract revenues for the applicable annual period (a “Performance Year”) and its Performance Year operating cash flow level (adjusted for certain amounts). Additionally, certain awards include three-year performance measures that, if met, result in supplemental shares awarded. For Performance RSUs, the Company evaluates compensation expense quarterly and recognizes expense for performance-based awards only if it determines it is probable that performance criteria for the awards will be met. Stock-based compensation expense and the related tax benefit recognized during the three and nine months ended October 29, 2022 and October 30, 2021 were as follows (dollars in thousands): For the Three Months Ended For the Nine Months Ended October 29, 2022 October 30, 2021 October 29, 2022 October 30, 2021 Stock-based compensation $ 4,515 $ 1,789 $ 12,273 $ 7,838 Income tax effect of stock-based compensation $ 1,113 $ 453 $ 3,031 $ 1,932 During the three months ended October 29, 2022 and October 30, 2021 the Company realized approximately $1.5 million and nominal amounts of net excess tax benefits, respectively, related to the vesting and exercise of share-based awards. During the nine months ended October 29, 2022 and October 30, 2021, the Company realized approximately $4.1 million and $2.8 million of net excess tax benefits, respectively. As of October 29, 2022, we had unrecognized compensation expense related to stock options, RSUs, and target Performance RSUs (based on the Company’s expected achievement of performance measures) of $3.0 million, $18.5 million, and $7.9 million, respectively. This expense will be recognized over a weighted-average number of years of 2.8, 2.6, and 1.6, respectively, based on the average remaining service periods for the awards. We may recognize an additional $21.3 million in compensation expense in future periods after October 29, 2022 if the maximum number of Performance RSUs is earned based on certain performance measures being met.

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

Commitment and Contingencies

Commitment and Contingencies	Oct. 29, 2022
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies On August 10, 2021, one of the Company’s subsidiaries was named in a putative class action lawsuit alleging claims on behalf of its non-exempt employees in California. The lawsuit alleges that the company failed to pay minimum and overtime wages, did not provide required meal and rest breaks, did not timely pay wages during employment and at the time of termination, provided noncompliant wage statements, failed to reimburse necessary business expenses, failed to keep requisite payroll records, and engaged in unfair business practices. On September 14, 2021, the same plaintiff bringing the putative class action filed a separate representative action under California’s Private Attorneys General Action (“PAGA”) seeking civil penalties relating to the same claims described above. Both lawsuits are in the very early stages. Due to the early stage of litigation, it is not possible to estimate a range of loss that could occur resulting from either an adverse judgment or a settlement of these matters. During the fourth quarter of fiscal 2016, one of the Company’s subsidiaries ceased operations. This subsidiary contributed to a multiemployer pension plan, the Pension, Hospitalization and Benefit Plan of the Electrical Industry - Pension Trust Fund (the “Plan”). In October 2016, the Plan demanded payment for a claimed withdrawal liability of approximately $13.0 million. In December 2016, the subsidiary submitted a formal request to the Plan seeking review of the Plan’s withdrawal liability determination. The subsidiary disputes the claim that it is required to make payment of a withdrawal liability as demanded by the Plan as it believes that a statutory exemption under the Employee Retirement Income Security Act (“ERISA”) applies to its activities. The Plan has taken the position that the work at issue does not qualify for that statutory exemption. The subsidiary has submitted this dispute to arbitration, as required by ERISA. In that proceeding, the arbitrator has issued an order indicating that the statutory exemption is not available to the Company’s subsidiary, and the Company’s subsidiary has appealed that determination to the District Court. As required by ERISA, in November 2016, this subsidiary began making payments of a withdrawal liability to the Plan in the amount of approximately $0.1 million per month. If the subsidiary prevails in disputing the withdrawal liability, all such payments are expected to be refunded. Given the early stage of this action, it is not possible to estimate a range of loss that could result from either an adverse judgment or a settlement of this matter. From time to time, we are party to other various claims and legal proceedings arising in the ordinary course of business. While the resolution of these matters cannot be predicted with certainty, it is the opinion of management, based on information available at this time, that the ultimate resolution of any such claims or legal proceedings will not, after considering applicable insurance coverage or other indemnities to which we may be entitled, have a material effect on our financial position, results of operations, or cash flow. Commitments Performance and Payment Bonds and Guarantees. We have obligations under performance and other surety contract bonds related to certain of our customer contracts. Performance bonds generally provide a customer with the right to obtain payment and/or performance from the issuer of the bond if we fail to perform our contractual obligations. As of October 29, 2022 and January 29, 2022, we had $289.0 million and $296.4 million, respectively, of outstanding performance and other surety contract bonds. In addition to performance and other surety contract bonds, as part of our insurance program we also provide surety bonds that collateralize our obligations to our insurance carriers. As of October 29, 2022 and January 29, 2022, we had $20.4 million and $20.3 million, respectively, of outstanding surety bonds related to our insurance obligations. Additionally, we periodically guarantee certain obligations of our subsidiaries, including obligations in connection with obtaining state contractor licenses and leasing real property and equipment. Letters of Credit. We have issued standby letters of credit under our Credit Agreement that collateralize our obligations to our insurance carriers. As of October 29, 2022 and January 29, 2022, we had $47.5 million and $46.3 million, respectively, of outstanding standby letters of credit issued under the Credit Agreement. Deferral of Employer Payroll Taxes. During 2020, the U.S. federal government enacted the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act), which provided for various tax relief and tax incentive measures. These measures did not have a material impact on our results of operations. However, pursuant to the CARES Act, we deferred the payment of $37.4 million of employer payroll taxes during the year ended December 31, 2020, 50% of which was paid by December 31, 2021 and the remainder is due by December 31, 2022.

Earnings Per Share [Abstract]
Schedule of Earnings Per Share Reconciliation	The following table sets forth the computation of basic and diluted earnings per common share (dollars in thousands, except per share amounts): For the Three Months Ended For the Nine Months Ended October 29, 2022 October 30, 2021 October 29, 2022 October 30, 2021 Net income available to common stockholders (numerator) $ 54,012 $ 28,717 $ 117,404 $ 47,780 Weighted-average number of common shares (denominator) 29,524,516 30,172,254 29,561,172 30,426,337 Basic earnings per common share $ 1.83 $ 0.95 $ 3.97 $ 1.57 Weighted-average number of common shares 29,524,516 30,172,254 29,561,172 30,426,337 Potential shares of common stock arising from stock options, and unvested restricted share units 454,279 442,452 446,085 502,553 Total shares-diluted (denominator) 29,978,795 30,614,706 30,007,257 30,928,890 Diluted earnings per common share $ 1.80 $ 0.94 $ 3.91 $ 1.54 Anti-dilutive weighted shares excluded from the calculation of earnings per common share: Stock-based awards 93,147 218,525 98,863 89,765 0.75% convertible senior notes due 2021 (1) (2) — 297,367 — 500,017 Warrants (1) (2) — 601,349 — 601,349 Total 93,147 1,117,241 98,863 1,191,131 (1) The Company used the treasury stock method for calculating any potential dilutive impact on earnings per common share if our average stock price for the period exceeded the $96.89 per share conversion price. There was no dilutive impact on earnings per common share during any of the periods presented as our average stock price did not exceed the per share conversion price and the 2021 Convertible Notes (as defined in Note 13) matured on September 15, 2021. The warrants associated with our 2021 Convertible Notes would have had a dilutive impact on earnings per common share if our average stock price for the period had exceeded the $130.43 per share warrant strike price. As our average stock price did not exceed the strike price for the warrants for any periods presented, the underlying common shares were anti-dilutive as reflected in the table above. The warrants were scheduled to expire on a series of dates concluding on May 9, 2022. During the fourth quarter of fiscal 2022, we purchased the remaining warrants for $0.7 million and there are no additional warrants outstanding. (2) In connection with the offering of the 2021 Convertible Notes, we entered into convertible note hedge transactions with counterparties for the purpose of reducing the potential dilution to common stockholders from the conversion of the 2021 Convertible Notes and offsetting any potential cash payments in excess of the principal amount of the 2021 Convertible Notes. Prior to conversion, the convertible note hedge was not included for purposes of the calculation of earnings per common share as its effect would be anti-dilutive. Upon any conversion, the convertible note hedge was expected to offset the dilutive effect of the 2021 Convertible Notes when the average stock price for the period was above $96.89 per share. The 2021 Convertible Notes matured on September 15, 2021. The convertible note hedge transactions expired on September 13, 2021. See Note 13, Debt , for additional information related to our 2021 Convertible Notes, warrant transactions, and hedge transactions.
