SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Dec. 30, 2023
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The Consolidated Financial Statements include the accounts of Valmont Industries, Inc. and its controlled subsidiaries (the “Company”). Investments in affiliates and joint ventures through which the Company exercises significant influence over but does not control the investee and is not the primary beneficiary of the investee's activities are accounted for using the equity method. All intercompany items have been eliminated. Fiscal Year The Company operates on a 52 or 53 week fiscal year with each fiscal year ending on the last Saturday in December. Accordingly, the Company’s fiscal year ended December 30, 2023 consisted of 52 weeks, the Company’s fiscal year ended December 31, 2022 consisted of 53 weeks, and the Company’s fiscal year ended December 25, 2021 consisted of 52 weeks. The estimated impact on the Company's results of operations due to the additional week in the fiscal year ended December 31, 2022 was additional net sales of approximately $80,800 and additional net earnings of approximately $5,300. Reportable Segments The Company has two reportable segments based on its management structure. Each segment is global in nature with a manager responsible for operational performance and allocation of capital. Reportable segments are as follows: INFRASTRUCTURE: This segment consists of the manufacture and distribution of products and solutions to serve the infrastructure markets of utility, solar, lighting, transportation, and telecommunications, along with coatings services to protect metal products. AGRICULTURE: This segment consists of the manufacture of center pivot components and linear irrigation equipment for agricultural markets, including parts and tubular products, and advanced technology solutions for precision agriculture. In addition to these two reportable segments, the Company had a business and related activities in fiscal 2022 that were not more than 10% of consolidated sales, operating income, or assets. This business, the offshore wind energy structures business, was reported in the “Other” segment until its divestiture in the fourth quarter of fiscal 2022. Cash Overdrafts Cash book overdrafts totaling $19,869 and $25,075 were classified as “Accounts payable” in the Consolidated Balance Sheets as of December 30, 2023 and December 31, 2022, respectively. The Company’s policy is to report the change in book overdrafts as “Cash flows from operating activities” in the Consolidated Statements of Cash Flows. Receivables Receivables are reported on the Consolidated Balance Sheets net of any allowance for credit losses. Allowances are maintained in amounts considered to be appropriate in relation to the outstanding receivables based on the age of the receivable, economic conditions, and customer credit quality. As the Company’s international business has grown, the exposure to potential losses in international markets has also increased. These exposures can be difficult to estimate, particularly in areas of political instability, with governments with which the Company has limited experience, or where there is a lack of transparency as to the current credit condition of governmental units. The following table details the balances of the allowance for credit losses and changes therein: Balance as of Charged to Currency Deductions Balance as of Beginning of Profit and Translation from Close of Fiscal year ended: Period Loss Adjustment Reserves Period December 30, 2023 $ 20,890 $ 17,657 $ 911 $ (6,561) $ 32,897 December 31, 2022 18,050 4,237 (522) (875) 20,890 December 25, 2021 15,952 3,379 (339) (942) 18,050 The Company sells trade accounts receivable at a discount under uncommitted trade accounts receivable sale programs to third-party financial institutions without recourse. As these accounts receivable are sold without recourse, the Company does not retain the associated risks following the transfer of such accounts receivable to the financial institutions. Transfers of accounts receivable are accounted for as sales and, accordingly, accounts receivable sold are excluded from “Receivables, less allowance” in the Consolidated Balance Sheets, and cash proceeds are reflected in “Cash flows from operating activities” in the Consolidated Statements of Cash Flows. The difference between the carrying amount of the trade accounts receivables sold and the cash received, or discount, is recorded in “Other income (expenses)” in the Consolidated Statements of Earnings. As of December 30, 2023 and December 31, 2022, the Company sold trade accounts receivable of $60,000 and $100,000, respectively. The fees associated with the trade accounts receivables factoring program are recognized within “Selling, general, and administrative expenses” in the Consolidated Statements of Earnings and were approximately $4,500 for the fiscal year ended December 30, 2023. Inventories Inventory is valued at the lower of cost, determined on the first-in, first-out method, or net realizable value. Finished goods and manufactured goods inventories include the costs of acquired raw materials and related factory labor and overhead charges required to convert raw materials to manufactured and finished goods. Long-Lived Assets Property, plant, and equipment are recorded at historical cost. The Company generally uses the straight-line method in computing depreciation and amortization for financial reporting purposes and accelerated methods for income tax purposes. The annual provisions for depreciation and amortization have been computed principally in accordance with the following ranges of asset lives: buildings and improvements - 10 to 30 years, machinery and equipment - 3 to 10 years, transportation equipment - 3 to 10 years, office furniture and equipment - 3 to 7 years, and intangible assets - 2 to 20 years. Depreciation expense was $78,138, $73,938, and $70,223 for the fiscal years ended December 30, 2023, December 31, 2022, and December 25, 2021, respectively. An impairment loss is recognized if the carrying amount of an asset may not be recoverable and exceeds the estimated future undiscounted cash flows of the asset. A recognized impairment loss reduces the carrying amount of the asset to its estimated fair value. The Company evaluates its reporting units for impairment of goodwill during the third quarter of each fiscal year or when events or changes in circumstances indicate the carrying value may not be recoverable. Reporting units are evaluated using after-tax operating cash flows (less capital expenditures) discounted to present value. Indefinite‑lived intangible assets are assessed separately from goodwill as part of the annual impairment testing using a relief-from-royalty method. If the underlying assumptions related to the valuation of a reporting unit’s goodwill or indefinite‑lived intangible assets change materially before or after the annual impairment testing, the reporting unit or asset is evaluated for potential impairment. In these evaluations, management considers recent operating performance, expected future performance, industry conditions, and other indicators of potential impairment. The Company recognized a pre-tax $21,415 impairment of property, plant, and equipment in fiscal 2021 when it determined that its offshore wind energy structures business reporting unit would not generate sufficient cash flows to recover the carrying values, recorded as “ Product cost of sales Leases The Company's operating lease right-of-use (“ROU”) assets are included in “Other non-current assets” and the corresponding lease obligations are included in “Other accrued expenses” and “Operating lease liabilities” in the Consolidated Balance Sheets. Income Taxes The Company uses the asset and liability method to calculate deferred income taxes. Deferred tax assets and liabilities are recognized on temporary differences between financial statement and tax bases of assets and liabilities using enacted tax rates. The effect of tax rate changes on deferred tax assets and liabilities is recognized in income during the period that includes the enactment date. Warranties The Company’s provision for product warranty reflects management’s best estimate of probable liability under its product warranties. Estimated future warranty costs are recorded at the time a sale is recognized. Future warranty liability is determined based on applying historical claim rate experience to units sold that are still within the warranty period. In addition, the Company records provisions for known warranty claims. Pension Cost (Benefit) Certain expenses are incurred in connection with a defined benefit pension plan. In order to measure the expense and the related benefit obligation, various assumptions are made including discount rates used to value the obligation, the expected return on plan assets used to fund these expenses, and the estimated future inflation rates. These assumptions are based on historical experience as well as current facts and circumstances. An actuarial analysis is used to measure the expense and liability associated with the pension cost (benefit). Stock Plans The Company maintains stock-based compensation plans approved by the shareholders, which provide that the Human Resources Committee of the Board of Directors may grant incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, restricted stock units, and bonuses of common stock. Fair Value The Company applies the provisions of Accounting Standards Codification 820, Fair Value Measurement Derivative Instruments The Company may enter into derivative financial instruments to manage risk associated with fluctuation in interest rates, foreign currency rates, or commodity prices. Where applicable, the Company may elect to account for such derivatives as either a cash flow, fair value, or net investment hedge. Comprehensive Income (Loss) Comprehensive income (loss) includes net earnings, foreign currency translation adjustments, certain derivative-related activity, and changes in prior service cost from the pension plan. Results of operations for foreign subsidiaries are translated using the average exchange rates during the period. Assets and liabilities are translated at the exchange rates in effect on the balance sheet dates. Accumulated other comprehensive income (loss) (“AOCI”) consisted of the following as of December 30, 2023 and December 31, 2022: December 30, December 31, 2023 2022 Foreign currency translation adjustments $ (236,690) $ (260,799) Hedging activities 20,989 20,099 Defined benefit pension plan (57,535) (34,209) Accumulated other comprehensive loss $ (273,236) $ (274,909) Revenue Recognition The Company determines the appropriate revenue recognition model for contracts by analyzing the type, terms, and conditions of each contract or arrangement with a customer. Contracts with customers for all businesses are fixed-price with sales tax excluded from revenue and do not include variable consideration. Discounts included in contracts with customers, typically early pay discounts, are recorded as a reduction of net sales in the period in which the sale is recognized. Contract revenues are classified as “Product sales” when the performance obligation is related to the manufacturing and sale of goods. Contract revenues are classified as “Service sales” when the performance obligation is the performance of a service. Service revenue is primarily related to the Coatings product line and Technology Products and Services product line. Customer acceptance provisions exist only in the design stage of our products (on a limited basis, the Company may agree to other acceptance terms), and acceptance of the design by the customer is required before manufacturing commences and the product is manufactured and delivered to the customer. The Company is generally not entitled to any compensation solely based on the design of the product and does not recognize this service as a separate performance obligation, therefore, no revenue is recognized for design services. No general rights of return exist for customers once the product has been delivered, and the Company establishes provisions for estimated warranties. Shipping and handling costs associated with sales are recorded within cost of sales. The Company elected to use the practical expedient of treating freight as a fulfillment obligation instead of a separate performance obligation and ratably recognize freight expense as the structure is being manufactured when the revenue from the associated customer contract is being recognized over time. With the exception of the Transmission, Distribution, and Substation ("TD&S"), Solar, and Telecommunications product lines, the Company’s inventory is interchangeable for a variety of each segment’s customers. The Company has elected to not disclose the partially satisfied performance obligation at the end of the period when the contract has an original expected duration of one year or less. In addition, the Company does not adjust the amount of consideration to be received in a contract for any significant financing component if payment is expected within one year of transfer of control of goods or services. Most of the Company’s customers are invoiced upon shipment or delivery of the goods to the customer’s specified location. Contract assets are recorded as revenue is recognized over time and such contract assets are relieved when the customer is invoiced. As of December 30, 2023 and December 31, 2022, the Company’s contract assets totaled $175,721 and $174,539, respectively. Certain customers are also invoiced by advanced billings or progress billings. When progress on performance obligations is less than the amount the customer has been billed, a contract liability is recognized. As of December 30, 2023, total contract liabilities of $70,978 were recorded as “Contract liabilities” in the Consolidated Balance Sheets. As of December 31, 2022, contract liabilities of $172,915 were recorded as “Contract liabilities” and $5,616 were recorded as “Other non-current liabilities” in the Consolidated Balance Sheets. Additional details are as follows: ● During the fiscal years ended December 30, 2023 and December 31, 2022, the Company recognized $162,182 and $96,373 of revenue that was included in the total contract liability as of December 31, 2022 and December 25, 2021, respectively. The revenue recognized was due to applying advance payments received for performance obligations completed during the period. ● As of December 30, 2023, the Company had no material remaining performance obligations on contracts with an original expected duration of one year or more. Segment and Product Line Revenue Recognition Infrastructure Segment Steel and concrete structures within the TD&S and Telecommunications product lines are engineered to customer specifications resulting in limited ability to sell the structure to a different customer if an order is canceled after production commences. The continuous transfer of control to the customer is evidenced either by contractual termination clauses or by rights to payment for work performed to date plus a reasonable profit as the products do not have an alternative use to the Company. Since control is transferred over time, revenue is recognized based on the extent of progress toward completion of the performance obligation. The selection of the method to measure progress toward completion requires judgment. For the structures manufactured within the TD&S and Telecommunications product lines, the Company generally recognizes revenue on an inputs basis, using total production hours incurred to date for each order as a percentage of total hours estimated to complete the order. The completion percentage is applied to the order’s total revenue and total estimated costs to determine reported revenue, cost of sales, and gross profit. Production of an order, once started, is typically completed within three months. Depending on the product sold, revenue from the Solar product line is recognized upon shipment or delivery of goods to the customer depending on contract terms, or by using an inputs method, based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. External sales agents are used in certain TD&S product line sales and the Company has chosen to expense estimated commissions owed to third parties by recognizing them proportionately as the goods are manufactured. For the structures sold for the Lighting and Transportation product line and for the majority of Telecommunications products, revenue is recognized upon shipment or delivery of goods to the customer depending on contract terms, which is the same point in time that the customer is billed. Some large regional customers have unique product specifications for telecommunication structures. When the customer contract includes a cancellation clause that would require them to pay for work completed plus a reasonable margin if an order was canceled, revenue is recognized over time based on hours worked as a percent of total estimated hours to complete production. The Coatings product line revenues are derived by providing coating services to customers’ products, which include galvanizing, anodizing, and powder coating. Revenue is recognized once the service has been performed and the goods are ready to be picked up or delivered to the customer, which is the same time that the customer is billed. Agriculture Segment Revenue recognition from the manufacture of irrigation equipment and related parts and services (including tubular products for industrial customers) is generally upon shipment of the goods to the customer which is the same point in time that the customer is billed. The remote monitoring subscription services recognized as part of the Technology Products and Services product line are primarily billed annually and revenue is recognized on a straight-line basis over the contract period. The disaggregation of revenue by product line is disclosed in Note 21. A breakdown by segment of revenue recognized over time and revenue recognized at a point in time for the fiscal years ended December 30, 2023, December 31, 2022, and December 25, 2021 was as follows: Fiscal Year Ended December 30, 2023 December 31, 2022 December 25, 2021 Point in Time Over Time Point in Time Over Time Point in Time Over Time Infrastructure $ 1,744,139 $ 1,255,498 $ 1,687,458 $ 1,222,288 $ 1,388,297 $ 973,227 Agriculture 1,144,633 30,328 1,307,681 27,604 996,278 20,772 Other — — — 100,219 — 123,001 Total net sales $ 2,888,772 $ 1,285,826 $ 2,995,139 $ 1,350,111 $ 2,384,575 $ 1,117,000 Use of Estimates Management of the Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities, the reported amounts of revenue and expenses, and the disclosure of contingent assets and liabilities to prepare the Consolidated Financial Statements in conformity with generally accepted accounting principles. Actual results could differ from those estimates. Equity Method Investments The Company has equity method investments in nonconsolidated subsidiaries which are recorded within “Other non-current assets” in the Consolidated Balance Sheets. Treasury Stock Repurchased shares are recorded as “Treasury stock, at cost” and result in a reduction of “Shareholders’ equity” in the Consolidated Balance Sheets. When treasury shares are reissued, the Company uses the last-in, first-out method, and the difference between the repurchase cost and re-issuance price is charged or credited to “Additional paid-in capital”. In May 2014, the Company announced a capital allocation philosophy that covered a share repurchase program. Specifically, the Board of Directors at that time authorized the purchase of up to $500,000 of the Company’s outstanding common stock from time to time over twelve months at prevailing market prices, through open market or privately negotiated transactions. In February 2015 and again in October 2018, the Board of Directors authorized an additional purchase of up to $250,000 of the Company’s outstanding common stock with no stated expiration date. In February 2023, the Board of Directors increased the amount remaining under the program by an additional $400,000, with no stated expiration date, bringing the total authorization to $1,400,000. As of December 30, 2023, the Company has acquired 7,895,724 shares for approximately $1,263,900 under this share repurchase program. In November 2023, the Company entered into an accelerated purchase agreement to repurchase $120,000 of the Company’s outstanding common stock (“November 2023 ASR”) with CitiBank, N.A. as counterparty. The November 2023 ASR was entered into under the Company’s previously announced share repurchase program described above. In the fourth quarter of fiscal 2023, the Company pre-paid $120,000 and received an initial delivery of 438,917 shares of common stock from CitiBank, which represented 75% of the prepayment amount divided by the closing price of $205.05 per share on November 28, 2023. The final number of shares to be delivered and the average price paid per share will be based on the daily volume weighted average share price during the term of the November 2023 ASR less a discount, which will be completed during the first quarter of fiscal 2024. Research and Development Research and development costs are charged to operations in the fiscal year incurred. These costs are a component of “Selling, general, and administrative expenses” in the Consolidated Statements of Earnings. During the fiscal years ended December 30, 2023, December 31, 2022, and December 25, 2021, research and development costs were approximately $55,000, $46,000, and $37,000, respectively. Supplier Finance Program In the first quarter of fiscal 2023, the Company adopted Accounting Standards Update No. 2022-04, Liabilities – Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations Confirmed obligations outstanding as of December 31, 2022 $ 48,880 Invoices confirmed during the period 264,051 Confirmed invoices paid during the period (271,015) Confirmed obligations outstanding as of December 30, 2023 $ 41,916 Redeemable Noncontrolling Interests Subsequent to the issuance of the Company’s Consolidated Financial Statements as of and for the year ended December 31, 2022, the Company identified an error in the presentation of “Noncontrolling interests in consolidated subsidiaries” of $60,865 as of December 31, 2022 December 25, 2021 December 26, 2020 Noncontrolling interests with redemption features that are not solely within the Company’s control are considered redeemable noncontrolling interests. The Company has redeemable noncontrolling interests in certain entities. The seller can require the Company to purchase their remaining ownership, known as a put right, for an amount and on a date specified in the applicable operating agreement. Likewise, the Company can require the seller to sell the Company their remaining ownership based on the same amount and timing, known as a call option. As a result of these redemption features, the Company records the noncontrolling interests as redeemable and classifies the balances in temporary equity in the Consolidated Balance Sheets initially at its acquisition-date fair value. The Company adjusts the redeemable noncontrolling interests each reporting period for the net income (loss) attributable to the noncontrolling interests and any redemption value adjustments. The redeemable noncontrolling interest is accreted to the future redemption value using the effective interest method up to the date on which the put right becomes effective. Any accretion adjustment in the current reporting period of the redeemable noncontrolling interest is offset against retained earnings and impacts earnings used in the calculation of earnings per share in the reporting period. As of December 30, 2023 and December 31, 2022, the redeemable noncontrolling interests were $62,792 and $60,865, respectively. The ultimate amount paid for the redeemable noncontrolling interests could be significantly different because the redemption amounts depend on the future results of operations of the businesses. Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures In December 2023, the FASB issued Accounting Standards Update No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures

The fair values assigned were $10,800 for goodwill and $2,627 for customer relationships, with the remainder representing net working capital. Goodwill was not deductible for tax purposes and the customer relationships will be amortized over eight years. The amount allocated to goodwill was primarily attributable to anticipated synergies and other intangibles that do not qualify for separate recognition. The Company finalized the purchase price allocation in the second quarter of fiscal 2022. Proforma disclosures were omitted for these acquisitions as they do not have a significant impact on the Company’s financial results. Acquisition-related costs incurred for the above acquisitions were insignificant for all fiscal years presented. Acquisitions of Redeemable Noncontrolling Interests Subsequent to fiscal 2023, on January 26, 2024, the Company acquired approximately 9% of ConcealFab for $7,227. Additionally, subsequent to fiscal 2023, the minority owner of a consolidated subsidiary exercised their put option to require the Company to purchase their remaining ownership.

The fair values of the reporting units were estimated using a discounted cash flow analysis which requires the Company to estimate the future cash flows as well as select a risk-adjusted discount rate to measure the present value of the anticipated cash flows. The carrying value for two of the reporting units, Agriculture Technology and India Structures, exceeded their respective estimated fair value. As a result, impairments of $120,000 and $1,915 were recognized in the Agriculture and Infrastructure segments, respectively, and recorded as “Impairment of goodwill and intangible assets” in the Consolidated Statements of Earnings. For the Agriculture Technology reporting unit, the recent less favorable outlook for the agriculture market in North America and the slower-than-expected adoption rate of the agronomy software solution led to a reduction in forecasted sales. These reduced forecasted cash flows resulted in a lower fair value of the Agriculture Technology reporting unit when discounted back to the present value.

The fiscal year ended December 31, 2022 included $8,166 of tax expense related to the divestiture of the offshore wind energy structures business for which no benefit was recorded. The fiscal year ended December 25, 2021 included $1,894 of U.S. tax benefits related to foreign taxes paid offset by $5,102 of valuation allowance recorded against the offshore wind energy structures business’ deferred tax assets. Deferred income taxes reflect the net tax effects of (a) temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, and (b) operating loss and tax credit carryforwards. The tax effects of significant items comprising the Company’s net deferred income tax assets (liabilities) as of December 30, 2023 and December 31, 2022 were as follows: December 30, December 31, 2023 2022 Deferred income tax assets: Accrued expenses and allowances $ 36,883 $ 25,927 Tax credits and loss carryforwards 58,519 67,249 Inventory allowances 8,427 7,912 Accrued compensation and benefits 23,880 24,398 Lease liabilities 41,769 40,709 Research and development expenditures 22,751 7,650 Deferred compensation 16,163 16,308 Gross deferred income tax assets 208,392 190,153 Valuation allowance (48,632) (48,974) Net deferred income tax assets 159,760 141,179 Deferred income tax liabilities: Property, plant, and equipment 42,299 45,300 Intangible assets 52,017 52,750 Defined benefit pension asset 3,851 6,054 Lease assets 42,717 40,708 Other deferred tax liabilities 6,616 4,941 Total deferred income tax liabilities 147,500 149,753 Net deferred income tax assets (liabilities) $ 12,260 $ (8,574) Deferred income tax assets (liabilities) were presented as follows as of December 30, 2023 and December 31, 2022 in the Consolidated Balance Sheets: December 30, December 31, 2023 2022 Other non-current assets $ 33,465 $ 32,517 Deferred income taxes (21,205) (41,091) Net deferred income tax assets (liabilities) $ 12,260 $ (8,574) Management of the Company has reviewed recent operating results and projected future operating results. The Company’s belief that realization of its net deferred tax assets is more likely than not is based on, among other factors, changes in operations that have occurred in recent fiscal years and available tax planning strategies. As of December 30, 2023 and December 31, 2022, respectively, there were $58,519 and $67,249 relating to tax credits and loss carryforwards. Valuation allowances have been established for certain losses that reduce deferred tax assets to an amount that will more likely than not be realized. During fiscal 2021, the Company recorded a valuation allowance of $6,472 against the tax attributes related to the acquisition of Prospera. The deferred tax assets as of December 30, 2023 that are associated with tax loss and tax credit carryforwards not reduced by valuation allowances expire in periods starting in 2024. Uncertain tax positions included in “Other non-current liabilities” in the Consolidated Balance Sheets are evaluated in a two-step process, whereby (1) the Company determines whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position and (2) for those tax positions that meet the more likely than not recognition threshold, the Company would recognize the largest amount of tax benefit that is greater than fifty percent likely to be realized upon ultimate settlement with the related tax authority. The following summarizes the activity related to the unrecognized tax benefits for the fiscal years ended December 30, 2023 and December 31, 2022: Fiscal Year Ended December 30, December 31, 2023 2022 Gross unrecognized tax benefits—beginning of period $ 2,536 $ 2,664 Gross increases—tax positions in prior period 2,174 1,133 Gross increases—current‑period tax positions 370 523 Settlements with taxing authorities (32) (1,576) Lapses of statutes of limitation (742) (208) Gross unrecognized tax benefits—end of period $ 4,306 $ 2,536 There are approximately $1,514 of uncertain tax positions for which reversal is reasonably possible during the next 12 months due to the closing of the statutes of limitation. The nature of these uncertain tax positions is generally the computation of a tax deduction or a tax credit. During the fiscal year ended December 30, 2023, the Company recorded a reduction of its gross unrecognized tax benefit of $742, with $586 recorded as a reduction of income tax expense, due to the expiration of statutes of limitation in the U.S. During the fiscal year ended December 31, 2022, the Company recorded a reduction of its gross unrecognized tax benefit of $208, with $165 recorded as a reduction of income tax expense, due to the expiration of statutes of limitation in the U.S. In addition to these amounts, there was an aggregate of $442 and $172 of interest and penalties as of December 30, 2023 and December 31, 2022, respectively. The Company’s policy is to record interest and penalties directly related to income taxes as “Income tax expense” in the Consolidated Statements of Earnings. The Company files income tax returns in the U.S. and various states as well as foreign jurisdictions. Tax years 2020 and forward remain open under U.S. statutes of limitation. The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $4,372 and $2,447 as of December 30, 2023 and December 31, 2022, respectively. The Organisation for Economic Co-operation and Development (“OECD”) has released the Pillar Two Model Rules Framework (the “Framework”) defining the global minimum tax rules, which contemplate a minimum tax rate of 15% and continues to release additional guidance. Although it is uncertain whether the U.S. will enact legislation to adopt the minimum tax directive, certain countries in which the Company operates have adopted legislation effective January 1, 2024, and other countries are in the process of introducing legislation to implement the minimum tax directive. Further, the OECD issued administrative guidance providing transition and safe harbor rules that could delay the impact of the minimum tax directive. The Company will continue to monitor the implementation of the Framework by the countries in which the Company operates. The Company does not expect the Framework to have a material impact on its Consolidated Financial Statements.

During the fiscal years ended December 30, 2023, December 31, 2022, and December 25, 2021, the Company granted restricted stock units to directors and certain management employees as follows (which are not included in the above stock plan activity tables): Fiscal Year Ended December 30, December 31, December 25, 2023 2022 2021 Restricted stock units granted 67,723 60,901 216,971 Weighted‑average per share price on grant date $ 233.96 $ 313.75 $ 236.28 Recognized compensation expense $ 22,478 $ 22,664 $ 16,147 During the second half of fiscal 2021, the Company granted 159,982 restricted stock units, worth $36,916, to certain employees of Prospera, of which 50,141 remain outstanding as of December 30, 2023. These restricted stock units vest in equal installments over four years and require the employees to continue employment over those four years. As such, the related compensation expense will be incurred over the vesting period. As of December 30, 2023, the amount of deferred stock‑based compensation granted, to be recognized over a weighted‑average period of 2.12 years, was approximately $33,933. Performance-based restricted stock units (“PSUs”) awards consist of shares of the Company’s stock which are payable upon the determination that the Company achieves certain established performance targets and can range from 0% to 200% of the targeted payout based on the actual results. PSUs granted in the fiscal years ended December 30, 2023 and December 31, 2022 have a performance period of three years. The fair value of each PSU granted is equal to the fair market value of the Company’s common stock on the date of grant. PSUs granted generally have a three-year period cliff vesting schedule; however, according to the grant agreements, if certain conditions are met, the employee (or beneficiary) will receive a prorated amount of the award based on active employment during the service period.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	(15) FAIR VALUE MEASUREMENTS The carrying amounts of cash and cash equivalents, receivables, accounts payable, notes payable to banks, and accrued expenses approximate fair value because of the short maturity of these instruments. The fair values of each of the Company’s long-term debt instruments are based on the amount of future cash flows associated with each instrument discounted using the Company’s current borrowing rate for similar debt instruments of comparable maturity. The fair value estimates are made at a specific point in time and the underlying assumptions are subject to change based on market conditions. As of December 30, 2023, the carrying amount of the Company’s long-term debt was $1,108,604 with an estimated fair value of approximately $1,064,916. As of December 31, 2022, the carrying amount of the Company’s long-term debt was $872,129 with an estimated fair value of approximately $807,281. ASC 820 establishes a three‑level hierarchy for fair value measurements based on the transparency of inputs to the valuation of an asset or liability as of the measurement date used. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories: ● Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. ● Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly ● Level 3: Unobservable inputs for the asset or liability. The categorization within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The following are descriptions of the valuation methodologies used for assets and liabilities measured at fair value: Trading Securities: Derivative Financial Instruments: Mutual Funds: Carrying Value Fair Value Measurement Using: December 30, 2023 Level 1 Level 2 Level 3 Trading securities $ 26,803 $ 26,803 $ — $ — Derivative financial instruments, net 2,860 — 2,860 — Cash and cash equivalents - mutual funds 6,258 6,258 — — Carrying Value Fair Value Measurement Using: December 31, 2022 Level 1 Level 2 Level 3 Trading securities $ 25,008 $ 25,008 $ — $ — Derivative financial instruments, net 1,404 — 1,404 — Cash and cash equivalents - mutual funds 7,205 7,205 — —

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	(16) DERIVATIVE FINANCIAL INSTRUMENTS The Company manages interest rate risk, commodity price risk, and foreign currency risk related to foreign currency denominated transactions and investments in foreign subsidiaries. Depending on the circumstances, the Company may manage these risks by utilizing derivative financial instruments. Some derivative financial instruments are marked to market and recorded in the Company’s Consolidated Statements of Earnings, while others may be accounted for as fair value, cash flow, or net investment hedges. Derivative financial instruments have credit and market risk. The Company manages these risks of derivative instruments by monitoring limits as to the types and degree of risk that can be taken and by entering into transactions with counterparties who are recognized, stable multinational banks. Any gains or losses from net investment hedge activities remain in AOCI until either the sale or substantially complete liquidation of the related subsidiaries. The fair value of derivative instruments as of December 30, 2023 and December 31, 2022 was as follows: December 30, December 31, Derivatives designated as hedging instruments: Balance Sheets location 2023 2022 Commodity contracts Prepaid expenses and other current assets $ 2,520 $ — Commodity contracts Other accrued expenses (1,586) (3,854) Foreign currency forward contracts Prepaid expenses and other current assets — 83 Cross currency swap contracts Prepaid expenses and other current assets 1,938 5,385 Cross currency swap contracts Other accrued expenses (12) (210) $ 2,860 $ 1,404 Gains (losses) on derivatives recognized in the Consolidated Statements of Earnings for the fiscal years ended December 30, 2023, December 31, 2022, and December 25, 2021 were as follows: Fiscal Year Ended Derivatives designated as Statements of December 30, December 31, December 25, hedging instruments: Earnings location 2023 2022 2021 Commodity contracts Product cost of sales $ (7,057) $ (5,212) $ 25,821 Foreign currency forward contracts Other income (expenses) 177 (45) (40) Interest rate hedge amortization Interest expense (64) (64) (64) Cross currency swap contracts Other income (expenses) — 4,827 — Cross currency swap contracts Interest expense 1,813 2,875 2,780 $ (5,131) $ 2,381 $ 28,497 Cash Flow Hedges The Company enters into commodity forward, swap, and option contracts that qualify as cash flow hedges of the variability in cash flows attributable to future purchases. The gain (loss) realized upon settlement for each will be recorded in “Product cost of sales” in the Consolidated Statements of Earnings in the period consumed. Notional amounts, purchase quantities, and maturity dates of these contracts as of December 30, 2023 were as follows: Notional Total Commodity Type Amount Purchase Quantity Maturity Dates Hot rolled steel coil $ 7,844 8,500 short tons December 2023 to April 2024 Natural gas 4,272 960,475 MMBtu January 2024 to October 2025 Diesel fuel 542 1,890,000 gallons January 2024 to September 2024 Net Investment Hedges In fiscal 2019, the Company entered into two fixed-for-fixed cross currency swaps ("CCS"), swapping U.S. dollar principal and interest payments on a portion of its 5.00% senior unsecured notes due in fiscal 2044 for Danish krone (“DKK”) and Euro denominated payments. The CCS were entered into in order to mitigate foreign currency risk on the Company’s Euro and DKK investments and to reduce interest expense. Interest is exchanged twice per year on April 1 and October 1. The Company designated the initial full notional amount of the two CCS ($130,000) as a hedge of the net investment in certain Danish and European subsidiaries under the spot method, with all changes in the fair value of the CCS that are included in the assessment of effectiveness (changes due to spot foreign exchange rates) recorded as cumulative foreign currency translation within AOCI. Net interest receipts will be recorded as a reduction of interest expense over the life of the CCS. In the third and fourth quarters of fiscal 2022, the Company settled the DKK CCS and received proceeds of $3,532. Due to the sale of the offshore wind energy structures business in the fourth quarter of fiscal 2022, the Company reclassified the cumulative net investment hedge gain of $4,827 ($3,620 after-tax) from AOCI to “Other income (expenses)” in the Consolidated Statements of Earnings. Key terms of the Euro CCS are as follows: Notional Swapped Set Settlement Currency Amount Termination Date Interest Rate Amount Euro $ 80,000 April 1, 2024 2.825% € 71,550

DEFINED BENEFIT RETIREMENT PLAN

DEFINED BENEFIT RETIREMENT PLAN	12 Months Ended
DEFINED BENEFIT RETIREMENT PLAN	Dec. 30, 2023
Retirement Benefits [Abstract]
DEFINED BENEFIT RETIREMENT PLAN	(19) DEFINED BENEFIT RETIREMENT PLAN Delta Ltd., a wholly-owned subsidiary of the Company, is the sponsor of the Delta Pension Plan (the "Plan"). The Plan provides defined benefit retirement income to eligible employees in the United Kingdom (“U.K.”). Pension retirement benefits to qualified employees are 1.67% of final salary per year of service upon reaching the age of 65 years. The Plan has no active employees as members as of December 30, 2023. Funded Status The Company recognizes the overfunded or underfunded status of the pension plan as an asset or liability. The funded status represents the difference between the projected benefit obligation (“PBO”) and the fair value of the plan assets. The PBO is the present value of benefits earned to date by plan participants, including the effect of assumed future salary increases (if applicable) and inflation. Plan assets are measured at fair value. Because the Plan is denominated in British pounds, the Company used exchange rates of $1.273/£ and $1.209/£ to translate the net pension asset into U.S. dollars as of December 30, 2023 and December 31, 2022, respectively. The PBO was $477,763 as of December 30, 2023. The net funded status of $15,404 as of December 30, 2023 is recorded as a non-current asset reflecting, in part, an actuarial loss for the period from December 31, 2022 to December 30, 2023 attributed to a slight decrease in the discount rate. Projected Benefit Obligation and Fair Value of Plan Assets As there are no active employees in the plan, the ABO is equal to the PBO for all years presented. The overfunded ABO represents the difference between the PBO and the fair value of plan assets. Changes in the PBO and fair value of plan assets for the Plan for the period from December 31, 2022 to December 30, 2023 were as follows: Projected Benefit Plan Funded Obligation Assets Status Fair value as of December 31, 2022 $ 435,711 $ 459,927 $ 24,216 Employer contributions — 17,345 Interest cost 21,555 — Actual return on plan assets — 10,966 Benefits paid (20,683) (20,683) Actuarial loss 17,692 — Currency translation 23,488 25,612 Fair value as of December 30, 2023 $ 477,763 $ 493,167 $ 15,404 The actuarial loss increased the projected benefit obligation and resulted primarily from a decrease in the discount rate from 4.80% in fiscal 2022 to 4.50% in fiscal 2023. Changes in the PBO and fair value of plan assets for the Plan for the period from December 25, 2021 to December 31, 2022 were as follows: Projected Benefit Plan Funded Obligation Assets Status Fair value as of December 25, 2021 $ 761,706 $ 761,170 $ (536) Employer contributions — 17,155 Interest cost 12,551 — Actual return on plan assets — (228,493) Benefits paid (20,175) (20,175) Actuarial gain (248,252) — Currency translation (70,119) (69,730) Fair value as of December 31, 2022 $ 435,711 $ 459,927 $ 24,216 The actuarial gain decreased the project benefit obligation and resulted from an increase in the discount rate from 1.90% in fiscal 2021 to 4.80% in fiscal 2022. Pre-tax amounts recognized in accumulated other comprehensive income (loss) as of December 30, 2023 and December 31, 2022 consisted of actuarial losses, as follows: Balance as of December 25, 2021 $ (60,940) Actuarial loss (2,915) Amortization of prior service costs 493 Currency translation gain 5,451 Balance as of December 31, 2022 (57,911) Actuarial loss (28,071) Amortization of prior service costs 498 Currency translation loss (3,667) Balance as of December 30, 2023 $ (89,151) Assumptions December 30, December 31, 2023 2022 Discount rate 4.50 % 4.80 % Salary increase N/A N/A Consumer Price Index ("CPI") inflation 2.25 % 2.35 % Retail Price Index ("RPI") inflation 3.05 % 3.25 % Cost/(Benefit) Pension cost (benefit) is determined based on the annual service cost of benefits (the actuarial cost of benefits earned during a period) and the interest cost on those liabilities, less the expected return on plan assets. The interest cost component is calculated using the full yield curve approach to estimate the interest cost by applying the specific spot rates along the yield curve used to determine the present value of the benefit plan obligations to relevant cash outflows for the corresponding year. The expected long-term rate of return on plan assets is applied to the fair value of plan assets. Differences in actual experience in relation to assumptions are not recognized in net earnings immediately, but are deferred and, if necessary, amortized as pension cost. The components of the net periodic pension cost (benefit) for the fiscal years ended December 30, 2023 and December 31, 2022 were as follows: Fiscal Year Ended December 30, December 31, 2023 2022 Interest cost $ 21,555 $ 12,551 Expected return on plan assets (21,804) (23,131) Amortization of prior service costs 498 493 Net periodic pension cost (benefit) $ 249 $ (10,087) Assumptions December 30, December 31, 2023 2022 Discount rate for benefit obligations 4.80 % 1.90 % Discount rate for interest cost 4.90 % 1.80 % Expected return on plan assets 4.85 % 3.48 % CPI inflation 2.35 % 2.70 % RPI inflation 3.25 % 3.30 % The discount rate is based on the yields of AA-rated corporate bonds with durational periods similar to that of the pension liabilities. The expected return on plan assets is based on the asset allocation mix and the historical return, taking into account current and expected market conditions. The expected return on plan assets increased from 3.48% to 4.85% for fiscal 2023 as the investment composition has more liability matching versus return-seeking assets. Inflation is based on expected changes in the CPI or the RPI in the U.K. depending on the relevant plan provisions. Cash Contributions The Company completed negotiations with Plan trustees in fiscal 2022 regarding annual funding for the Plan. The annual contributions into the Plan are approximately $16,700 (£13,100) per annum as part of the Plan’s recovery plan, along with a contribution to cover the administrative costs of the Plan of approximately $1,700 (£1,300) per annum. In the fourth quarter of fiscal 2020, the Company made its required fiscal 2021 annual contribution in addition to the required fiscal 2020 annual contribution that was made earlier in fiscal 2020. Benefit Payments The following table details expected pension benefit payments for the fiscal years 2024 through 2033: 2024 $ 21,641 2025 22,278 2026 23,042 2027 23,678 2028 24,442 2029 - 2033 133,540 Asset Allocation Strategy The investment strategy for pension plan assets is to maintain a diversified portfolio consisting of ● Long-term fixed-income securities that are investment grade or government ‑ backed in nature, ● Common stock mutual funds in U.K. and non-U.K. companies, and ● Diversified growth funds, which are invested in a number of investments, including common stock, fixed income funds, properties, and commodities. The Plan, as required by U.K. law, has an independent trustee that sets investment policy. The general strategy is to invest approximately 50% of the assets of the Plan in common stock mutual funds and diversified growth funds, with the remainder of the investments in long-term fixed income securities, including corporate bonds and index-linked U.K. gilts. The trustees regularly consult with representatives of the Plan sponsor and independent advisors on such matters. The pension plan investments are held in a trust. The weighted average maturity of the corporate bond portfolio was 13 years as of December 30, 2023. Fair Value Measurements The pension plan assets are valued at fair value. The following is a description of the valuation methodologies used for the investments measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy. Leveraged Inflation-Linked Gilts Temporary Cash Investments Corporate Bonds Corporate Stock Secured Income Asset Funds As of December 30, 2023 and December 31, 2022, the pension plan assets measured at fair value on a recurring basis were as follows: Fair Value Measurement Using: December 30, 2023 Level 1 Level 2 Level 3 Total Plan assets at fair value: Temporary cash investments $ 7,077 $ — $ — $ 7,077 Plan assets at NAV: Leveraged inflation-linked gilt funds 216,405 Corporate bonds 74,440 Corporate stock 72,548 Secured income asset funds 122,697 Total plan assets at NAV 486,090 Total plan assets $ 493,167 Fair Value Measurement Using: December 31, 2022 Level 1 Level 2 Level 3 Total Plan assets at fair value: Temporary cash investments $ 5,916 $ — $ — $ 5,916 Plan assets at NAV: Leveraged inflation-linked gilt funds 206,555 Corporate bonds 63,953 Corporate stock 55,379 Secured income asset funds 128,124 Total plan assets at NAV 454,011 Total plan assets $ 459,927

Leases [Abstract]
LEASES	(20) LEASES The Company has operating leases for plant locations, corporate offices, sales offices, and certain equipment. Outstanding leases as of December 30, 2023 have remaining lease terms of one year to twenty-three years, some of which include options to extend leases for up to ten years. The Company does not have any financing leases. The Company elected to not separate lease and non-lease components for all classes of underlying assets. The Company determines if an arrangement is a lease at inception. Operating leases are included in “Other non-current assets”, “Other accrued expenses”, and “Operating lease liabilities” in the Consolidated Balance Sheets. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make future lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The Company used its collateralized incremental borrowing rate in determining the present value of future lease payments. The operating lease ROU assets are adjusted for any lease payments made, lease incentives, and impairments. The lease terms for some of the Company’s facility leases include options to extend the lease when it is reasonably certain that the option will be exercised. Lease expense is recognized on a straight-line basis over the lease term. Lease cost and other information related to the Company’s operating leases as of and for the fiscal year ended December 30, 2023 and December 31, 2022 were as follows: December 30, December 31, 2023 2022 Operating lease cost $ 33,714 $ 31,062 Operating cash outflows from operating leases $ 34,967 $ 33,150 ROU assets obtained in exchange for lease obligations $ 25,688 $ 27,480 Weighted average remaining lease term 16 years 17 years Weighted average discount rate 4.4 % 4.2 % Operating lease cost includes approximately $1,900 for short-term lease costs and approximately $4,800 for variable lease payments in fiscal 2023.

Segment Reporting [Abstract]
BUSINESS SEGMENTS	(21) BUSINESS SEGMENTS The Company has two reportable segments based on its management structure. Each segment is global in nature with a manager responsible for segment operational performance and the allocation of capital within the segment. Net corporate expense is net of certain service‑related expenses that are allocated to business units generally based on employee headcounts and sales dollars. Reportable segments are as follows: INFRASTRUCTURE: This segment consists of the manufacture and distribution of products and solutions to serve the infrastructure markets of utility, solar, lighting, transportation, and telecommunications, along with coatings services to protect metal products. AGRICULTURE: This segment consists of the manufacture of center pivot components and linear irrigation equipment for agricultural markets, including parts and tubular products, and advanced technology solutions for precision agriculture. In addition to these two reportable segments, the Company had a business and related activities in fiscal 2022 that were not more than 10% of consolidated sales, operating income, or assets. This business, the offshore wind energy structures business, was reported in the “Other” segment until its divestiture in the fourth quarter of fiscal 2022. The accounting policies of the reportable segments are the same as those described in Note 1. The Company evaluates the performance of its reportable segments based on operating income and return on invested capital. The Company’s operating income for segment purposes excludes unallocated corporate general and administrative expenses, interest expense, non-operating income and deductions, or income taxes.

Long-lived assets by geographical area are based on the location of facilities.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Dec. 30, 2023
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The Consolidated Financial Statements include the accounts of Valmont Industries, Inc. and its controlled subsidiaries (the “Company”). Investments in affiliates and joint ventures through which the Company exercises significant influence over but does not control the investee and is not the primary beneficiary of the investee's activities are accounted for using the equity method. All intercompany items have been eliminated.
Fiscal Year	Fiscal Year The Company operates on a 52 or 53 week fiscal year with each fiscal year ending on the last Saturday in December. Accordingly, the Company’s fiscal year ended December 30, 2023 consisted of 52 weeks, the Company’s fiscal year ended December 31, 2022 consisted of 53 weeks, and the Company’s fiscal year ended December 25, 2021 consisted of 52 weeks. The estimated impact on the Company's results of operations due to the additional week in the fiscal year ended December 31, 2022 was additional net sales of approximately $80,800 and additional net earnings of approximately $5,300.
Reportable Segments	Reportable Segments The Company has two reportable segments based on its management structure. Each segment is global in nature with a manager responsible for operational performance and allocation of capital. Reportable segments are as follows: INFRASTRUCTURE: This segment consists of the manufacture and distribution of products and solutions to serve the infrastructure markets of utility, solar, lighting, transportation, and telecommunications, along with coatings services to protect metal products. AGRICULTURE: This segment consists of the manufacture of center pivot components and linear irrigation equipment for agricultural markets, including parts and tubular products, and advanced technology solutions for precision agriculture. In addition to these two reportable segments, the Company had a business and related activities in fiscal 2022 that were not more than 10% of consolidated sales, operating income, or assets. This business, the offshore wind energy structures business, was reported in the “Other” segment until its divestiture in the fourth quarter of fiscal 2022.
Cash Overdrafts	Cash Overdrafts Cash book overdrafts totaling $19,869 and $25,075 were classified as “Accounts payable” in the Consolidated Balance Sheets as of December 30, 2023 and December 31, 2022, respectively. The Company’s policy is to report the change in book overdrafts as “Cash flows from operating activities” in the Consolidated Statements of Cash Flows.
Accounts Receivable	Receivables Receivables are reported on the Consolidated Balance Sheets net of any allowance for credit losses. Allowances are maintained in amounts considered to be appropriate in relation to the outstanding receivables based on the age of the receivable, economic conditions, and customer credit quality. As the Company’s international business has grown, the exposure to potential losses in international markets has also increased. These exposures can be difficult to estimate, particularly in areas of political instability, with governments with which the Company has limited experience, or where there is a lack of transparency as to the current credit condition of governmental units. The following table details the balances of the allowance for credit losses and changes therein: Balance as of Charged to Currency Deductions Balance as of Beginning of Profit and Translation from Close of Fiscal year ended: Period Loss Adjustment Reserves Period December 30, 2023 $ 20,890 $ 17,657 $ 911 $ (6,561) $ 32,897 December 31, 2022 18,050 4,237 (522) (875) 20,890 December 25, 2021 15,952 3,379 (339) (942) 18,050 The Company sells trade accounts receivable at a discount under uncommitted trade accounts receivable sale programs to third-party financial institutions without recourse. As these accounts receivable are sold without recourse, the Company does not retain the associated risks following the transfer of such accounts receivable to the financial institutions. Transfers of accounts receivable are accounted for as sales and, accordingly, accounts receivable sold are excluded from “Receivables, less allowance” in the Consolidated Balance Sheets, and cash proceeds are reflected in “Cash flows from operating activities” in the Consolidated Statements of Cash Flows. The difference between the carrying amount of the trade accounts receivables sold and the cash received, or discount, is recorded in “Other income (expenses)” in the Consolidated Statements of Earnings. As of December 30, 2023 and December 31, 2022, the Company sold trade accounts receivable of $60,000 and $100,000, respectively. The fees associated with the trade accounts receivables factoring program are recognized within “Selling, general, and administrative expenses” in the Consolidated Statements of Earnings and were approximately $4,500 for the fiscal year ended December 30, 2023.
Inventories	Inventories Inventory is valued at the lower of cost, determined on the first-in, first-out method, or net realizable value. Finished goods and manufactured goods inventories include the costs of acquired raw materials and related factory labor and overhead charges required to convert raw materials to manufactured and finished goods.
Long-Lived Assets	Long-Lived Assets Property, plant, and equipment are recorded at historical cost. The Company generally uses the straight-line method in computing depreciation and amortization for financial reporting purposes and accelerated methods for income tax purposes. The annual provisions for depreciation and amortization have been computed principally in accordance with the following ranges of asset lives: buildings and improvements - 10 to 30 years, machinery and equipment - 3 to 10 years, transportation equipment - 3 to 10 years, office furniture and equipment - 3 to 7 years, and intangible assets - 2 to 20 years. Depreciation expense was $78,138, $73,938, and $70,223 for the fiscal years ended December 30, 2023, December 31, 2022, and December 25, 2021, respectively. An impairment loss is recognized if the carrying amount of an asset may not be recoverable and exceeds the estimated future undiscounted cash flows of the asset. A recognized impairment loss reduces the carrying amount of the asset to its estimated fair value. The Company evaluates its reporting units for impairment of goodwill during the third quarter of each fiscal year or when events or changes in circumstances indicate the carrying value may not be recoverable. Reporting units are evaluated using after-tax operating cash flows (less capital expenditures) discounted to present value. Indefinite‑lived intangible assets are assessed separately from goodwill as part of the annual impairment testing using a relief-from-royalty method. If the underlying assumptions related to the valuation of a reporting unit’s goodwill or indefinite‑lived intangible assets change materially before or after the annual impairment testing, the reporting unit or asset is evaluated for potential impairment. In these evaluations, management considers recent operating performance, expected future performance, industry conditions, and other indicators of potential impairment. The Company recognized a pre-tax $21,415 impairment of property, plant, and equipment in fiscal 2021 when it determined that its offshore wind energy structures business reporting unit would not generate sufficient cash flows to recover the carrying values, recorded as “ Product cost of sales
Leases	Leases The Company's operating lease right-of-use (“ROU”) assets are included in “Other non-current assets” and the corresponding lease obligations are included in “Other accrued expenses” and “Operating lease liabilities” in the Consolidated Balance Sheets.
Income Taxes	Income Taxes The Company uses the asset and liability method to calculate deferred income taxes. Deferred tax assets and liabilities are recognized on temporary differences between financial statement and tax bases of assets and liabilities using enacted tax rates. The effect of tax rate changes on deferred tax assets and liabilities is recognized in income during the period that includes the enactment date.
Warranties	Warranties The Company’s provision for product warranty reflects management’s best estimate of probable liability under its product warranties. Estimated future warranty costs are recorded at the time a sale is recognized. Future warranty liability is determined based on applying historical claim rate experience to units sold that are still within the warranty period. In addition, the Company records provisions for known warranty claims.
Pension Cost (Benefit)	Pension Cost (Benefit) Certain expenses are incurred in connection with a defined benefit pension plan. In order to measure the expense and the related benefit obligation, various assumptions are made including discount rates used to value the obligation, the expected return on plan assets used to fund these expenses, and the estimated future inflation rates. These assumptions are based on historical experience as well as current facts and circumstances. An actuarial analysis is used to measure the expense and liability associated with the pension cost (benefit).
Stock Plans	Stock Plans The Company maintains stock-based compensation plans approved by the shareholders, which provide that the Human Resources Committee of the Board of Directors may grant incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, restricted stock units, and bonuses of common stock.
Fair Value	Fair Value The Company applies the provisions of Accounting Standards Codification 820, Fair Value Measurement
Derivative Instrument	Derivative Instruments The Company may enter into derivative financial instruments to manage risk associated with fluctuation in interest rates, foreign currency rates, or commodity prices. Where applicable, the Company may elect to account for such derivatives as either a cash flow, fair value, or net investment hedge.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) includes net earnings, foreign currency translation adjustments, certain derivative-related activity, and changes in prior service cost from the pension plan. Results of operations for foreign subsidiaries are translated using the average exchange rates during the period. Assets and liabilities are translated at the exchange rates in effect on the balance sheet dates. Accumulated other comprehensive income (loss) (“AOCI”) consisted of the following as of December 30, 2023 and December 31, 2022: December 30, December 31, 2023 2022 Foreign currency translation adjustments $ (236,690) $ (260,799) Hedging activities 20,989 20,099 Defined benefit pension plan (57,535) (34,209) Accumulated other comprehensive loss $ (273,236) $ (274,909)
Revenue Recognition	Revenue Recognition The Company determines the appropriate revenue recognition model for contracts by analyzing the type, terms, and conditions of each contract or arrangement with a customer. Contracts with customers for all businesses are fixed-price with sales tax excluded from revenue and do not include variable consideration. Discounts included in contracts with customers, typically early pay discounts, are recorded as a reduction of net sales in the period in which the sale is recognized. Contract revenues are classified as “Product sales” when the performance obligation is related to the manufacturing and sale of goods. Contract revenues are classified as “Service sales” when the performance obligation is the performance of a service. Service revenue is primarily related to the Coatings product line and Technology Products and Services product line. Customer acceptance provisions exist only in the design stage of our products (on a limited basis, the Company may agree to other acceptance terms), and acceptance of the design by the customer is required before manufacturing commences and the product is manufactured and delivered to the customer. The Company is generally not entitled to any compensation solely based on the design of the product and does not recognize this service as a separate performance obligation, therefore, no revenue is recognized for design services. No general rights of return exist for customers once the product has been delivered, and the Company establishes provisions for estimated warranties. Shipping and handling costs associated with sales are recorded within cost of sales. The Company elected to use the practical expedient of treating freight as a fulfillment obligation instead of a separate performance obligation and ratably recognize freight expense as the structure is being manufactured when the revenue from the associated customer contract is being recognized over time. With the exception of the Transmission, Distribution, and Substation ("TD&S"), Solar, and Telecommunications product lines, the Company’s inventory is interchangeable for a variety of each segment’s customers. The Company has elected to not disclose the partially satisfied performance obligation at the end of the period when the contract has an original expected duration of one year or less. In addition, the Company does not adjust the amount of consideration to be received in a contract for any significant financing component if payment is expected within one year of transfer of control of goods or services. Most of the Company’s customers are invoiced upon shipment or delivery of the goods to the customer’s specified location. Contract assets are recorded as revenue is recognized over time and such contract assets are relieved when the customer is invoiced. As of December 30, 2023 and December 31, 2022, the Company’s contract assets totaled $175,721 and $174,539, respectively. Certain customers are also invoiced by advanced billings or progress billings. When progress on performance obligations is less than the amount the customer has been billed, a contract liability is recognized. As of December 30, 2023, total contract liabilities of $70,978 were recorded as “Contract liabilities” in the Consolidated Balance Sheets. As of December 31, 2022, contract liabilities of $172,915 were recorded as “Contract liabilities” and $5,616 were recorded as “Other non-current liabilities” in the Consolidated Balance Sheets. Additional details are as follows: ● During the fiscal years ended December 30, 2023 and December 31, 2022, the Company recognized $162,182 and $96,373 of revenue that was included in the total contract liability as of December 31, 2022 and December 25, 2021, respectively. The revenue recognized was due to applying advance payments received for performance obligations completed during the period. ● As of December 30, 2023, the Company had no material remaining performance obligations on contracts with an original expected duration of one year or more. Segment and Product Line Revenue Recognition Infrastructure Segment Steel and concrete structures within the TD&S and Telecommunications product lines are engineered to customer specifications resulting in limited ability to sell the structure to a different customer if an order is canceled after production commences. The continuous transfer of control to the customer is evidenced either by contractual termination clauses or by rights to payment for work performed to date plus a reasonable profit as the products do not have an alternative use to the Company. Since control is transferred over time, revenue is recognized based on the extent of progress toward completion of the performance obligation. The selection of the method to measure progress toward completion requires judgment. For the structures manufactured within the TD&S and Telecommunications product lines, the Company generally recognizes revenue on an inputs basis, using total production hours incurred to date for each order as a percentage of total hours estimated to complete the order. The completion percentage is applied to the order’s total revenue and total estimated costs to determine reported revenue, cost of sales, and gross profit. Production of an order, once started, is typically completed within three months. Depending on the product sold, revenue from the Solar product line is recognized upon shipment or delivery of goods to the customer depending on contract terms, or by using an inputs method, based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. External sales agents are used in certain TD&S product line sales and the Company has chosen to expense estimated commissions owed to third parties by recognizing them proportionately as the goods are manufactured. For the structures sold for the Lighting and Transportation product line and for the majority of Telecommunications products, revenue is recognized upon shipment or delivery of goods to the customer depending on contract terms, which is the same point in time that the customer is billed. Some large regional customers have unique product specifications for telecommunication structures. When the customer contract includes a cancellation clause that would require them to pay for work completed plus a reasonable margin if an order was canceled, revenue is recognized over time based on hours worked as a percent of total estimated hours to complete production. The Coatings product line revenues are derived by providing coating services to customers’ products, which include galvanizing, anodizing, and powder coating. Revenue is recognized once the service has been performed and the goods are ready to be picked up or delivered to the customer, which is the same time that the customer is billed. Agriculture Segment Revenue recognition from the manufacture of irrigation equipment and related parts and services (including tubular products for industrial customers) is generally upon shipment of the goods to the customer which is the same point in time that the customer is billed. The remote monitoring subscription services recognized as part of the Technology Products and Services product line are primarily billed annually and revenue is recognized on a straight-line basis over the contract period. The disaggregation of revenue by product line is disclosed in Note 21. A breakdown by segment of revenue recognized over time and revenue recognized at a point in time for the fiscal years ended December 30, 2023, December 31, 2022, and December 25, 2021 was as follows: Fiscal Year Ended December 30, 2023 December 31, 2022 December 25, 2021 Point in Time Over Time Point in Time Over Time Point in Time Over Time Infrastructure $ 1,744,139 $ 1,255,498 $ 1,687,458 $ 1,222,288 $ 1,388,297 $ 973,227 Agriculture 1,144,633 30,328 1,307,681 27,604 996,278 20,772 Other — — — 100,219 — 123,001 Total net sales $ 2,888,772 $ 1,285,826 $ 2,995,139 $ 1,350,111 $ 2,384,575 $ 1,117,000
Use of Estimates	Use of Estimates Management of the Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities, the reported amounts of revenue and expenses, and the disclosure of contingent assets and liabilities to prepare the Consolidated Financial Statements in conformity with generally accepted accounting principles. Actual results could differ from those estimates.
Equity Method Investments	Equity Method Investments The Company has equity method investments in nonconsolidated subsidiaries which are recorded within “Other non-current assets” in the Consolidated Balance Sheets.
Treasury Stock	Treasury Stock Repurchased shares are recorded as “Treasury stock, at cost” and result in a reduction of “Shareholders’ equity” in the Consolidated Balance Sheets. When treasury shares are reissued, the Company uses the last-in, first-out method, and the difference between the repurchase cost and re-issuance price is charged or credited to “Additional paid-in capital”. In May 2014, the Company announced a capital allocation philosophy that covered a share repurchase program. Specifically, the Board of Directors at that time authorized the purchase of up to $500,000 of the Company’s outstanding common stock from time to time over twelve months at prevailing market prices, through open market or privately negotiated transactions. In February 2015 and again in October 2018, the Board of Directors authorized an additional purchase of up to $250,000 of the Company’s outstanding common stock with no stated expiration date. In February 2023, the Board of Directors increased the amount remaining under the program by an additional $400,000, with no stated expiration date, bringing the total authorization to $1,400,000. As of December 30, 2023, the Company has acquired 7,895,724 shares for approximately $1,263,900 under this share repurchase program. In November 2023, the Company entered into an accelerated purchase agreement to repurchase $120,000 of the Company’s outstanding common stock (“November 2023 ASR”) with CitiBank, N.A. as counterparty. The November 2023 ASR was entered into under the Company’s previously announced share repurchase program described above. In the fourth quarter of fiscal 2023, the Company pre-paid $120,000 and received an initial delivery of 438,917 shares of common stock from CitiBank, which represented 75% of the prepayment amount divided by the closing price of $205.05 per share on November 28, 2023. The final number of shares to be delivered and the average price paid per share will be based on the daily volume weighted average share price during the term of the November 2023 ASR less a discount, which will be completed during the first quarter of fiscal 2024.
Research and Development	Research and Development Research and development costs are charged to operations in the fiscal year incurred. These costs are a component of “Selling, general, and administrative expenses” in the Consolidated Statements of Earnings. During the fiscal years ended December 30, 2023, December 31, 2022, and December 25, 2021, research and development costs were approximately $55,000, $46,000, and $37,000, respectively.
Supplier Finance Program	Supplier Finance Program In the first quarter of fiscal 2023, the Company adopted Accounting Standards Update No. 2022-04, Liabilities – Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations Confirmed obligations outstanding as of December 31, 2022 $ 48,880 Invoices confirmed during the period 264,051 Confirmed invoices paid during the period (271,015) Confirmed obligations outstanding as of December 30, 2023 $ 41,916
Redeemable Noncontrolling Interests	Redeemable Noncontrolling Interests Subsequent to the issuance of the Company’s Consolidated Financial Statements as of and for the year ended December 31, 2022, the Company identified an error in the presentation of “Noncontrolling interests in consolidated subsidiaries” of $60,865 as of December 31, 2022 December 25, 2021 December 26, 2020 Noncontrolling interests with redemption features that are not solely within the Company’s control are considered redeemable noncontrolling interests. The Company has redeemable noncontrolling interests in certain entities. The seller can require the Company to purchase their remaining ownership, known as a put right, for an amount and on a date specified in the applicable operating agreement. Likewise, the Company can require the seller to sell the Company their remaining ownership based on the same amount and timing, known as a call option. As a result of these redemption features, the Company records the noncontrolling interests as redeemable and classifies the balances in temporary equity in the Consolidated Balance Sheets initially at its acquisition-date fair value. The Company adjusts the redeemable noncontrolling interests each reporting period for the net income (loss) attributable to the noncontrolling interests and any redemption value adjustments. The redeemable noncontrolling interest is accreted to the future redemption value using the effective interest method up to the date on which the put right becomes effective. Any accretion adjustment in the current reporting period of the redeemable noncontrolling interest is offset against retained earnings and impacts earnings used in the calculation of earnings per share in the reporting period. As of December 30, 2023 and December 31, 2022, the redeemable noncontrolling interests were $62,792 and $60,865, respectively. The ultimate amount paid for the redeemable noncontrolling interests could be significantly different because the redemption amounts depend on the future results of operations of the businesses.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures In December 2023, the FASB issued Accounting Standards Update No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures
