SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 12 Months Ended
--- | ---
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

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” in the Consolidated Statements of Earnings. See Note 8 for details of impairments of goodwill and other intangible assets recognized during the fiscal years ended December 30, 2023 and December 25, 2021.
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 (“ASC 820”), which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. The provisions of ASC 820 apply to other accounting pronouncements that require or permit fair value measurements. As defined in ASC 820, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
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,

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:
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

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, as well as early adopted the amendment on rollforward information. During fiscal 2019, the Company entered into an agreement with a third-party financial institution to facilitate a supplier finance program that allows qualifying suppliers to sell their receivables from the Company to the financial institution. These participating suppliers negotiate their outstanding receivable arrangements directly with the financial institution and the Company’s rights and obligations to suppliers are not impacted. The Company has no economic interest in a supplier’s decision to enter into these agreements. Once a qualifying supplier elects to participate in the supplier finance program and reaches an agreement with a financial institution, they elect which individual Company invoices they sell to the financial institution. The Company’s obligation is to make payment in the invoice amount negotiated with participating suppliers to the financial institution on the invoice due date, regardless of whether the individual invoice is sold by the supplier to the financial institution. The financial institution pays the supplier on the invoice due date for any invoices that were not previously sold under the supplier finance program. The invoice amounts and scheduled payment terms are not impacted by the suppliers’ decisions to sell amounts under these arrangements. The payment of these obligations is included in “Cash flows from operating activities” in the Consolidated Statements of Cash Flows. As of December 30, 2023 and December 31, 2022, there were $41,916 and $48,880 of outstanding payment obligations, respectively, that were sold to the financial institution under the Company’s supplier finance program included in “Accounts payable” in the Consolidated Balance Sheets. ​
​ | ​ | ​ | ​
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, $26,750 as of December 25, 2021, and $25,774 as of December 26, 2020, that has been corrected in the current year. Such amounts were previously reported within “Total shareholders’ equity” and have been revised in the December 31, 2022 Consolidated Balance Sheets and the Consolidated Statements of Shareholders’ Equity and Redeemable Noncontrolling Interests to be presented as “Redeemable noncontrolling interests” outside of “Total shareholders’ equity”. We have evaluated the materiality of this error based on an analysis of quantitative and qualitative factors and concluded it was not material to the prior period financial statements, individually or in aggregate. 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, which improves the disclosures about reportable segments including more detailed information about a reportable segment’s expenses. This guidance will be effective for the fiscal year ending December 28, 2024 and the interim periods thereafter, with early adoption permitted. The guidance will have no effect on the Company’s results of operations as the changes are primarily disclosure related. In December 2023, the FASB issued Accounting Standards Update No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances the transparency and decision usefulness of income tax disclosures, primarily related to the rate reconciliation and income taxes paid information. This guidance will be effective on a prospective basis for the fiscal year ending December 27, 2025, with early adoption permitted. The guidance will have no effect on the Company’s results of operations as the changes are primarily disclosure related.
