SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Dec. 31, 2023
Accounting Policies [Abstract]  
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Consolidation. The consolidated financial statements reflect the accounts of the Company and its wholly-owned and majority-owned subsidiaries. All significant intercompany profits, transactions, and balances have been eliminated in consolidation.
Reclassifications. Certain prior period amounts have been reclassified to conform to the current year presentation.
Use of Estimates. The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that directly affect the amounts reported in its consolidated financial statements and accompanying notes. Actual results could differ from these estimates.
Cash and Cash Equivalents. Cash and cash equivalents include all highly liquid investments with a maturity of three months or less at the time of purchase.
Accounts Receivable. Accounts receivable are shown net of expected losses and primarily include trade receivables. The Company records expected losses for customers based upon a variety of factors including the Company’s historical collection experience, the length of time the account has been outstanding, and the financial condition of the customer. If the circumstances related to specific customers were to change, the Company’s estimates of expected losses with respect to the collectability of the related accounts could be further adjusted. The Company’s policy is to write-off receivables when they are determined to be uncollectible. Expected losses are charged to General and administrative expenses and Selling expenses in the Consolidated Statements of Operations. The following table presents the changes in expected losses (in thousands):
Years ended December 31,

Expected losses651 179 10 
Write-offs, net of recoveries— (180)(117)
Balance at end of year$1,079 $428 $429 
Inventories. Inventories are stated at the lower of cost, determined on either the first-in, first-out or average cost method, or net realizable value. The cost of manufactured inventory includes raw material, labor and overhead.
Prepaid Expenses and Other. Prepaid expenses and other as of December 31, 2023 and 2022 consists of the following (in thousands):
December 31,
20232022
Chassis converter pool agreements$27,312 $20,345 
Income tax receivables11,840 2,358 
Insurance premiums & maintenance/subscription agreements5,899 3,949 
Commodity swap contracts1,511 2,674 
All other4,895 5,601 
$51,457 $34,927 
Chassis converter pool agreements represent chassis transferred to the Company on a restricted basis by the manufacturer, who retains the sole authority to authorize commencement of work on the chassis and to make certain other decisions with respect to the chassis including the terms and pricing of sales to the manufacturer’s dealers. As further described in Note 11, commodity swap contracts relate to our hedging activities (that are in an asset position) to mitigate the risks associated with fluctuations in commodity prices. Insurance premiums and maintenance/subscription agreements are charged to expense over the contractual life, which is generally one year or less. Other items primarily consist of investments held by the Company’s captive insurance subsidiary and other various prepaid and other assets. As of December 31, 2023 and 2022, there was no restricted cash included in prepaid expenses and other current assets.
Property, Plant, and Equipment. Property, plant, and equipment are recorded at cost, net of accumulated depreciation. Maintenance and repairs are charged to expense as incurred, while expenditures that extend the useful life of an asset are capitalized. Depreciation is recorded using the straight-line method over the estimated useful lives of the depreciable assets. The estimated useful lives are up to 33 years for buildings and building improvements and range from three to ten years for machinery and equipment.
Goodwill. Goodwill represents the excess purchase price over fair value of the net assets acquired. The Company determines its reporting units at the individual operating segment level, or one level below, when there is discrete financial information available that is regularly reviewed by segment management for evaluating operating results. The Company reviews goodwill for impairment, at the reporting unit level, annually on October 1 and whenever events or changes in circumstances indicate its carrying value may not be recoverable. In accordance with ASC 350, Intangibles - Goodwill and Other, goodwill is reviewed for impairment utilizing either a qualitative assessment or a quantitative process.
The Company has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. An entity has an unconditional option to bypass the qualitative assessment in any period and proceed directly to performing the quantitative impairment test, which is the option the Company has historically chosen.
For reporting units in which the Company performs the quantitative analysis, the Company compares the carrying value, including goodwill, of each reporting unit with its estimated fair value. If the fair value of the reporting unit exceeds its carrying value, the goodwill is not considered impaired. If the carrying value is greater than the fair value, the difference is recognized as an impairment loss charged to the reporting unit. After an impairment loss is recognized, the adjusted carrying amount of goodwill shall be its new accounting basis.
As of December 31, 2023, goodwill allocated to the Transportation Solutions (“TS”) and Parts & Services (“P&S”) segments was approximately $120.5 million and $67.9 million, respectively.
For the 2023 annual goodwill impairment test conducted as of October 1st, 2023, the Company chose to evaluate qualitative factors to determine if it was more likely than not that the fair value of the TS and P&S reporting units were less than their respective carrying amounts. In accordance with the relevant accounting guidance, in order to perform the qualitative assessment, the Company considered many factors including, but not limited to, general economic conditions, industry and market conditions, financial performance and key business drivers, future operating plans, and potential changes to significant assumptions used in the most recent quantitative fair value analysis for each reporting unit (which was conducted in connection with the Company’s segment realignment beginning in September 2021 as further described below). Based on the analysis of the factors and considerations described above, the Company concluded that it was more likely than not that the fair value of each reporting unit continued to be greater than the respective carrying value. Therefore, no impairment charges were recorded and a quantitative analysis was not performed.
During the fourth quarters of 2022 and 2021, the Company completed its annual goodwill impairment test using the qualitative assessment. Based on all assessments performed, the Company believed it was more likely than not that the fair value of its reporting units were greater than their carrying amount and no additional impairment of goodwill was recognized.
In connection with the Company’s segment realignment beginning in September 2021 described in greater detail below, the Company performed a quantitative assessment for each reporting unit utilizing a combination of the income and market approaches, the results of which were weighted evenly. No impairment was indicated in either annual test as the fair value of each reporting unit exceeded its respective carrying value.
Long-Lived Assets. Long-lived assets, consisting primarily of intangible assets and property, plant, and equipment, are reviewed for impairment whenever facts and circumstances indicate that the carrying amount may not be recoverable. Specifically, this process involves comparing an asset’s carrying value to the estimated undiscounted future cash flows the asset is expected to generate over its remaining life. If this process were to result in the conclusion that the carrying value of a long-lived asset would not be recoverable, a write-down of the asset to fair value would be recorded through a charge to operations. Fair value is determined based upon discounted cash flows or appraisals as appropriate.
During the first quarter of 2022, the Company impaired approximately $1.0 million of construction-in-progress projects that were no longer expected to be completed.
As further described in Note 5, in connection with the Company’s rebranding initiative the Company recorded non-cash impairment charges of approximately $28.3 million during the fourth quarter of 2021 related to trade name and trademark intangible assets due to the significant reduction in the related useful lives of these assets. Net intangible assets of approximately $1.3 million were written-off during the second quarter of 2021 in connection with the Extract® Technology divestiture.
Other Assets. The Company capitalizes the cost of computer software developed or obtained for internal use. Capitalized software is amortized using the straight-line method over three to seven years. As of December 31, 2023 and 2022, the Company had software costs, net of amortization, of $8.0 million and $3.3 million, respectively. Amortization expense for 2023, 2022, and 2021 was $1.9 million, $1.8 million, and $1.7 million, respectively.
Warranties. The Company offers a limited warranty for its products with a coverage period that ranges between one and five years, except that the coverage period for DuraPlate® trailer panels is ten years. The Company passes through component manufacturers’ warranties to our customers. The Company’s policy is to accrue the estimated cost of warranty coverage at the time of the sale.

Self-Insured Liabilities. The Company is self-insured up to specified limits for medical and workers’ compensation coverage. The self-insurance reserves have been recorded to reflect the undiscounted estimated liabilities, including claims incurred but not reported, as well as catastrophic claims as appropriate.
The following table presents the changes in the self-insurance accrual included in Other accrued liabilities (in thousands):

Payments(39,297)(34,891)
Balance as of December 31$11,311 $10,718 
Income Taxes. The Company determines its provision or benefit for income taxes under the asset and liability method. The asset and liability method measures the expected tax impact at current enacted rates of future taxable income or deductions resulting from differences in the tax and financial reporting basis of assets and liabilities reflected in the Consolidated Balance Sheets. Future tax benefits of tax losses and credit carryforwards are recognized as deferred tax assets. Deferred tax assets are reduced by a valuation allowance to the extent management determines that it is more-likely-than-not the Company would not realize the value of these assets.
The Company accounts for income tax contingencies by prescribing a “more-likely-than-not” recognition threshold that a tax position is required to meet before being recognized in the financial statements.
Used Trailer Trade Commitments. The Company may accept trade-in of used trailers when a customer enters into a contract to purchase a new trailer. However, in the contracts for the sale of the new trailers, there is no commitment to repurchase that trailer or a similar trailer in the future. The Company had $0.5 million and no outstanding trade commitments as of December 31, 2023 and December 31, 2022, respectively. On occasion, the amount of the trade allowance provided for in the used trailer commitments, or cost, may exceed the net realizable value of the underlying used trailer. In these instances, the Company’s policy is to recognize the loss related to these commitments at the time the new trailer revenue is recognized. Net realizable value of used trailers is measured considering market sales data for comparable types of trailers.
Concentration of Credit Risk. Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash, cash equivalents, and customer receivables. We place our cash and cash equivalents with high quality financial institutions. Generally, we do not require collateral or other security to support customer receivables.
Research and Development. Research and development expenses are charged to Cost of sales and General and administrative expenses in the Consolidated Statements of Operations as incurred and were $7.5 million, $5.3 million, and $13.6 million in 2023, 2022, and 2021, respectively.

Accounting Standards Update and Change in Accounting Principle [Abstract]  
NEW ACCOUNTING PRONOUNCEMENTS NEW ACCOUNTING PRONOUNCEMENTS
In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (“ASU”) No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses, allowing financial statement users to better understand the components of a segment's profit or loss to assess potential future cash flows for each reportable segment and the entity as a whole. The amendments expand a public entity's segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker ("CODM"), clarifying when an entity may report one or more additional measures to assess segment performance, requiring enhanced interim disclosures, providing new disclosure requirements for entities with a single reportable segment, and requiring other new disclosures. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and early adoption is permitted. Although the ASU only requires additional disclosures about the Company's operating segments, the Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which is intended to enhance the transparency, decision usefulness and effectiveness of income tax disclosures. The amendments in this ASU require a public entity to disclose a tabular tax rate reconciliation, using both percentages and currency, with specific categories. A public entity is also required to provide a qualitative description of the states and local jurisdictions that make up the majority of the effect of the state and local income tax category and the net amount of income taxes paid, disaggregated by federal, state and foreign taxes and also disaggregated by individual jurisdictions. The amendments also remove certain disclosures that are no longer considered cost beneficial. The amendments are effective prospectively for annual periods beginning after December 15, 2024, and early adoption and retrospective application are permitted. Although the ASU only modifies the Company's required income tax disclosures, the Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements.

Revenue from Contract with Customer [Abstract]  
REVENUE RECOGNITION REVENUE RECOGNITION
The Company recognizes revenue from the sale of its products when obligations under the terms of a contract with our customers are satisfied; this occurs with the transfer of control of our products and replacement parts or throughout the completion of service work. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring promised goods or services to a customer and excludes all taxes collected from the customer. Shipping and handling fees are included in Net sales and the associated costs are included in Cost of sales in the Consolidated Statements of Operations. For shipping and handling costs that take place after the transfer of control, the Company applies the practical expedient and treats it as a fulfillment cost. Incidental items that are immaterial in the context of the contract are recognized as expense. For performance obligations satisfied over time, which includes service work whereby the customer simultaneously receives and consumes the benefits provided, and also included certain equipment-related sales within our Parts & Services reportable segment prior to the sale of our Extract Technology® business during the second quarter of 2021 that had no alternative use and contained an enforceable right to payment, the Company recognizes revenue on the basis of the Company’s efforts or inputs to the satisfaction of these performance obligations, measured by actual total cost incurred to the total estimated costs for each project. Total revenue recognized over time was not material to the consolidated financial statements for all periods presented.
The Company has identified three separate and distinct performance obligations: (1) the sale of a trailer or equipment, (2) the sale of replacement parts, and (3) service work. For trailer, truck body, equipment, and replacement part sales, control is transferred and revenue is recognized from the sale upon shipment to or pick up by the customer in accordance with the contract terms. The Company does not have any material extended payment terms as payment is received shortly after the point of sale. Accounts receivable are recorded when the right to consideration becomes unconditional. The Company does have customers who pay for the product prior to the transfer of control, which is recorded as customer deposits in Other accrued liabilities as shown in Note 9. Customer deposits are recognized as revenue when the Company performs its obligations under the contract and transfers control of the product.

GOODWILL AND OTHER INTANGIBLE ASSETS GOODWILL AND OTHER INTANGIBLE ASSETS
Goodwill and Related Annual Impairment Assessments
As of December 31, 2023, goodwill allocated to the Transportation Solutions (“TS”) and Parts & Services (“P&S”) segments was approximately $120.5 million and $67.9 million, respectively.
For the 2023 annual goodwill impairment test conducted as of October 1st, 2023, the Company chose to evaluate qualitative factors to determine if it was more likely than not that the fair value of the TS and P&S reporting units were less than their respective carrying amounts. In accordance with the relevant accounting guidance, in order to perform the qualitative assessment, the Company considered many factors including, but not limited to, general economic conditions, industry and market conditions, financial performance and key business drivers, future operating plans, and potential changes to significant assumptions used in the most recent quantitative fair value analysis for each reporting unit (which was conducted in connection with the Company’s segment realignment beginning in September 2021 as further described below). Based on the analysis of the factors and considerations described above, the Company concluded that it was more likely than not that the fair value of each reporting unit continued to be greater than the respective carrying value. Therefore, no impairment charges were recorded and a quantitative analysis was not performed.
During the fourth quarters of 2022 and 2021, the Company completed its annual goodwill impairment test using the qualitative assessment. Based on all assessments performed, the Company believed it was more likely than not that the fair value of its reporting units were greater than their carrying amount and no additional impairment of goodwill was recognized.
In connection with the Company’s segment realignment beginning in September 2021 described in greater detail below, the Company performed a quantitative assessment for each reporting unit utilizing a combination of the income and market approaches, the results of which were weighted evenly. No impairment was indicated in either annual test as the fair value of each reporting unit exceeded its respective carrying value.
2021 Segment Realignment
As further described in Note 20, beginning in September 2021 the Company realigned its operating and reportable segments. Based on these changes, the Company established two operating and reportable segments: Transportation Solutions (“TS”) and Parts & Services (“P&S”). These operating and reportable segments were also determined to be the applicable reporting units for purposes of goodwill assignment and evaluation. In accordance with the relevant accounting guidance, the Company performed a quantitative impairment assessment of goodwill immediately prior to and subsequently following the change in segments and reporting units. The quantitative analyses did not result in any impairment charges as the fair value of each reporting unit exceeded the carrying value. In addition, as part of the change in segment structure, the Company reassigned goodwill from the historical Commercial Trailer Products (“CTP”), Diversified Products (“DPG”), and Final Mile Products (“FMP”) reporting units to the TS and P&S reporting units using a relative fair value allocation approach as required by the relevant accounting guidance.
2021 Goodwill Allocation for Extract Technology®
As further described in Note 21, during the second quarter of 2021, the Company sold its Extract Technology® (“Extract”) business that manufactured stainless steel isolators and downflow booths, as well as custom-fabricated equipment, including workstations and drum booths for the pharmaceutical, fine chemical, biotech, and nuclear end markets. Prior to the divestiture, Extract was an operating unit within the historical DPG reporting unit. In accordance with the relevant accounting guidance, as part of the sale the Company allocated $11.1 million of goodwill based upon the relative fair value of the Extract operating unit compared to the historical DPG reporting unit as a whole. This goodwill was included in the carrying value of the disposed assets and the resulting net gain recognized in connection with the sale. Prior to and subsequent to the divestiture, the Company performed an impairment assessment for the historical DPG reporting unit and concluded the fair value of the reporting unit continued to exceed the carrying value.
For the years ended December 31, 2023, 2022, and 2021, the changes in the carrying amounts of goodwill were as follows (in thousands):

Intangible asset amortization expense was $12.8 million, $15.2 million, and $22.9 million for 2023, 2022, and 2021, respectively. Annual intangible asset amortization expense for the next 5 fiscal years is estimated to be $12.2 million in 2024; $11.2 million in 2025; $10.7 million in 2026; $10.2 million in 2027; and $9.7 million in 2028.
As further described throughout our Annual Report on Form 10-K for the year ended December 31, 2021, on January 10, 2022, the Company completed its review and approval of its plan for rebranding as Wabash®. As part of the planning process, the Company assessed its usage of trade names and brand names in connection with the long-term growth strategy as One Wabash. Under the plan as approved, the Company no longer uses certain trade names or brand names, and predominantly uses Wabash (or variations thereof) to refer to the Company. The decision resulted in non-cash impairment charges of approximately $28.3 million (of which approximately $25.6 million related to the TS operating segment and $2.7 million to the P&S operating segment) during the fourth quarter of 2021 related to trade name and trademark intangible assets due to the significant reduction in the related useful lives of these assets. The impairment charges are included in Impairment and other, net in the Consolidated Statements of Operations.
Net intangible assets of approximately $1.3 million were written-off during the second quarter of 2021 in connection with the Extract® divestiture.

NONCONTROLLING INTEREST AND VARIABLE INTEREST ENTITIES (VIEs)

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
NONCONTROLLING INTEREST AND VARIABLE INTEREST ENTITIES (VIEs) NONCONTROLLING INTEREST AND VARIABLE INTEREST ENTITIES (“VIEs”)
VIEs & Consolidation
The Company consolidates those entities in which it has a direct or indirect controlling financial interest based on either the variable interest model (the “VIE model”) or the voting interest model (the “VOE model”).
VIEs are entities that, by design, either (i) lack sufficient equity to permit the entity to finance its activities without additional subordinated financial support from other parties, or (ii) have equity investors that do not have the ability to make significant decisions relating to the entity’s operations through voting rights, or do not have the obligation to absorb the expected losses, or do not have the right to receive the residual returns of the entity.
The primary beneficiary of a VIE is required to consolidate the assets and liabilities of the VIE. The primary beneficiary is the party that has both (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance; and (ii) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE through its interest in the VIE.
To assess whether the Company has the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, the Company considers all the facts and circumstances, including its role in establishing the VIE and its ongoing rights and responsibilities. This assessment includes identifying the activities that most significantly impact the VIE’s economic performance and identifying which party, if any, has power over those activities. In general, the parties that make the most significant decisions affecting the VIE (typically management and representation on the board of directors as well as control of the overall strategic direction of the entity) and have the right to unilaterally remove those decision-makers are deemed to have the power to direct the activities of a VIE.
To assess whether the Company has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, the Company considers all of its economic interests, which primarily include the obligation to absorb losses or fund expenditures or losses (if needed), that are deemed to be variable interests in the VIE. This assessment requires the Company to apply judgment in determining whether these interests, in the aggregate, are considered potentially significant to the VIE. Factors considered in assessing the significance include: the design of the VIE, including its capitalization structure; subordination of interests; payment priority; relative share of interests held across various classes within the VIE’s capital structure; and the reasons why the interests are held by the Company.
At the VIE’s inception, the Company determines whether it is the primary beneficiary and if the VIE should be consolidated based on the facts and circumstances. The Company then performs on-going reassessments of the VIE based on reconsideration events and reevaluates whether a change to the consolidation conclusion is required each reporting period. If the Company is not deemed to be the primary beneficiary in a VIE, the Company accounts for the investment or other variable interests in a VIE in accordance with the applicable GAAP.
Entities that do not qualify as a VIE are assessed for consolidation under the VOE model. Under the VOE model, the Company consolidates the entity if it determines that it, directly or indirectly, has greater than 50% of the voting shares and that other equity holders do not have substantive voting, participating or liquidation rights. The Company has no entities consolidated under the VOE model.
At each reporting period, the Company reassesses whether it remains the primary beneficiary for VIEs consolidated under the VIE model.
If the Company concludes it is not the primary beneficiary of a VIE, the Company evaluates whether it has the ability to exercise significant influence over operating and financial policies of the entity requiring the equity method of accounting. The Company’s judgment regarding the level of influence over an equity method investment includes, but is not limited to, considering key factors such as the Company’s ownership interest (generally represented by ownership of at least 20 percent but not more than 50 percent), representation on the board of directors, participation in policy making decisions, technological dependency, and material intercompany transactions. Generally, under the equity method, investments are recorded at cost and subsequently adjusted by the Company’s share of equity in income or losses after the date of the initial investment. Equity in income or losses is recorded according to the Company’s level of ownership; if losses accumulate, the Company records its share of losses until the investment has been fully depleted. If the Company’s investment has been fully depleted, the Company recognizes additional losses only when it is committed to provide further financial support. Dividends received from equity method investees reduce the amount of the Company’s investment when received and do not impact the Company’s earnings. The Company evaluates its equity method investments for an other-than-temporary impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may not be recoverable.
Linq Venture Holdings LLC
During the fourth quarter of 2023, the Company continued to unify and expand its parts and services capabilities and ecosystem by executing an agreement with a partner to create a new legal entity (Linq Venture Holdings LLC, “Linq”) to develop and scale a digital marketplace in and for the transportation and logistics distribution industry. Linq is intended to be the digital channel to market Wabash equipment and parts & services, as well as non-Wabash parts & services, in a digital marketplace format to end-customers as well as dealers. The Company holds 49% ownership of the membership units in Linq while its partner holds 51%. Initial capital contributions to Linq were in proportion to the respective ownership interests. The Company’s initial capital contribution was approximately $2.5 million while its partner’s contribution was approximately $2.6 million. At its formation, Linq has no debt or other financial obligations other than typical operating expenses and costs. Creditors of Linq do not have recourse to the general credit of the Company. The operating agreement requires excess cash distributions, as defined in the agreement, no later than 30 days after the end of the second and fourth quarters of each year in proportion to the respective ownership interests.
The operating agreement provides the Company’s partner with put rights that would require the Company to purchase its partner’s interest in Linq. In addition, the operating agreement provides the Company with call rights that would allow it to purchase its partner’s interest in Linq. These put and call rights vary depending upon when they may be exercised, which is generally from formation of Linq up to and including the seven-year anniversary of formation. Upon receiving notice that the Company’s partner has exercised the put right or the Company has exercised the call right, a valuation will occur as stipulated within the operating agreement. Generally, the valuation stipulated within the operating agreement is materially equivalent to a fair value calculation. Such put and call rights have not been exercised by the Company’s partner or the Company as of the current period end date.
Because Linq does not have sufficient equity at risk to permit it to carry on its activities without additional financial support, the Company concluded that Linq is a VIE. The Company has the ability to significantly influence the activities of Linq through minority representation on the Board of Directors as well as through participation in certain management and strategic decisions of Linq. The Company’s partner is responsible for the overall development and management of the digital marketplace, the primary purpose for which Linq was formed. Both the Company and its partner have a requirement to provide funding to Linq if needed.
As part of the formation of Linq, the Company executed a credit agreement with Linq whereby a $10.0 million revolving line of credit (the “Wabash Note”) with a 7% simple accrued interest rate, paid quarterly, is available to Linq. The commitment under the Wabash Note may be increased to $35.0 million subject to the approval of the Board of Directors as stipulated in the operating agreement. As of and through December 31, 2023, there were no amounts borrowed under the Wabash Note and the Company did not provide financial or other support to Linq that it was not contractually obligated to provide.
Given the facts and circumstances specific to Linq, the Company concluded that it is not the primary beneficiary of this VIE. However, the Company has the ability to exercise significant influence over the operating and financial policies of Linq. The Company’s maximum exposure to loss in this unconsolidated VIE is limited to the Company’s initial capital contribution and any amounts borrowed under the Wabash Note. The partner’s put right does not have a standalone value as it based upon a fair value calculation when exercised, as stipulated in the operating agreement.
The Company’s equity method investment in Linq is recorded in Investment in unconsolidated entity on its Consolidated Balance Sheets. Any amounts borrowed under the Wabash Note are recorded in Other assets on the Company’s Consolidated Balance Sheets. Linq is considered operationally integral. The Company’s share of the results from its equity method investment is included in Loss from unconsolidated entity in the Consolidated Statements of Operations.

Wabash Parts LLC
During the second quarter of 2022, the Company unified and expanded its parts and distribution capabilities by executing an agreement with a partner to create a new legal entity (Wabash Parts LLC, “WP”) to operate a parts and services distribution platform. The Company holds 50% ownership in WP while its partner holds the remaining 50%. Initial capital contributions were insignificant. WP has no debt or other financial obligations other than typical operating expenses and costs. Creditors of WP do not have recourse to the general credit of the Company. The operating agreement requires excess cash distributions, as defined in the agreement, no later than 30 days after the end of the second and fourth quarters of each year in proportion to the respective ownership interests.
The operating agreement provides the Company’s partner with a put right that would require the Company to purchase its partner’s interest in WP. Upon receiving notice that the Company’s partner has exercised the put right, a valuation will occur as stipulated within the operating agreement. Such put right has not been exercised by the Company’s partner and is therefore not mandatorily redeemable as of the current period end date, however the existence of the put right that is beyond the Company’s control requires the noncontrolling interest to be presented in the temporary equity section of the Company’s Consolidated Balance Sheets.
Because the entity does not have sufficient equity at risk to permit it to carry on its activities without additional financial support, the Company concluded that WP is a VIE. The Company has the power to direct the activities of WP through majority representation on the Board of Directors as well as control related to the management and overall strategic direction of the entity. In addition, the Company has the obligation to absorb the benefits and losses of WP that could potentially be significant to the entity. The Company also has a requirement to provide funding to the entity if needed. Given the facts and circumstances specific to WP, the Company concluded that it is the primary beneficiary and, as such, is required to consolidate the entity. WP’s results of operations are included in the Parts & Services operating and reportable segment. Through December 31, 2023, the Company did not provide financial or other support to this VIE that it was not contractually obligated to provide. As of December 31, 2023, the Company does not have any obligations to provide financial support to WP.

Senior Notes due 2028
On October 6, 2021, the Company closed on an offering of $400 million in aggregate principal amount of its 4.50% unsecured Senior Notes due 2028 (the “New Senior Notes”). The New Senior Notes were issued pursuant to an indenture dated as of October 6, 2021, by and among the Company, certain subsidiary guarantors named therein (the “Guarantors”) and Wells Fargo Bank, National Association, as trustee (the “Indenture”). The New Senior Notes bear interest at the rate of 4.50% and pay interest semi-annually in cash in arrears on April 15 and October 15 of each year. The New Senior Notes will mature on October 15, 2028. At any time prior to October 15, 2024, the Company may redeem some or all of the New Senior Notes for cash at a redemption price equal to 100% of the aggregate principal amount of the New Senior Notes being redeemed plus an applicable make-whole premium set forth in the Indenture and accrued and unpaid interest to, but not including, the redemption date.
Prior to October 15, 2024, the Company may redeem up to 40% of the New Senior Notes at a redemption price of 104.500% of the principal amount, plus accrued and unpaid interest to, but not including, the redemption date, with the proceeds of certain equity offerings so long as if, after any such redemption occurs, at least 60% of the aggregate principal amount of the New Senior Notes remain outstanding. On and after October 15, 2024, the Company may redeem some or all of the New Senior Notes at redemption prices (expressed as percentages of principal amount) equal to 102.250% for the twelve-month period beginning on October 15, 2024, 101.125% for the twelve-month period beginning October 15, 2025 and 100.000% beginning on October 15, 2026, plus accrued and unpaid interest to, but not including, the redemption date. Upon the occurrence of a Change of Control (as defined in the Indenture), unless the Company has exercised its optional redemption right in respect of the New Senior Notes, the holders of the New Senior Notes will have the right to require the Company to repurchase all or a portion of the New Senior Notes at a price equal to 101% of the aggregate principal amount of the New Senior Notes, plus any accrued and unpaid interest to, but not including, the date of repurchase.
The New Senior Notes are guaranteed on a senior unsecured basis by all direct and indirect existing and future domestic restricted subsidiaries, subject to certain restrictions. The New Senior Notes and related guarantees are the Company’s and the Guarantors’ general unsecured senior obligations and will be subordinated to all of the Company and the Guarantors’ existing and future secured debt to the extent of the assets securing that secured obligation. In addition, the New Senior Notes are structurally subordinated to any existing and future debt of any of the Company’s subsidiaries that are not Guarantors, to the extent of the assets of those subsidiaries.
Subject to a number of exceptions and qualifications, the Indenture restricts the Company’s ability and the ability of certain of its subsidiaries to: (i) incur additional indebtedness; (ii) pay dividends or make other distributions in respect of, or repurchase or redeem, its capital stock or with respect to any other interest or participation in, or measured by, its profits; (iii) make loans and certain investments; (iv) sell assets; (v) create or incur liens; (vi) enter into transactions with affiliates; and (vii) consolidate, merge or sell all or substantially all of its assets. These covenants are subject to a number of important exceptions and qualifications.
During any time when the New Senior Notes are rated investment grade by at least two of Moody’s, Fitch and Standard & Poor’s Ratings Services and no Default (as defined in the Indenture) has occurred and is continuing, many of such covenants will be suspended and the Company and its subsidiaries will cease to be subject to such covenants during such period.
The Indenture contains customary events of default, including payment defaults, breaches of covenants, failure to pay certain judgments and certain events of bankruptcy, insolvency and reorganization. If an event of default occurs and is continuing, the principal amount of the New Senior Notes, plus accrued and unpaid interest, if any, may be declared immediately due and payable. These amounts automatically become due and payable if an event of default relating to certain events of bankruptcy, insolvency or reorganization occurs. As of December 31, 2023, the Company was in compliance with all covenants.
The sale of the New Senior Notes resulted in net proceeds of approximately $395 million, after deducting financing fees and other offering expenses. The Company used the net proceeds of the New Senior Notes and a portion of the $50 million draw from the increased capacity under the Revolving Credit Agreement to fund the redemption in full of the Senior Notes due 2025, to repay in full the $108.8 million of outstanding borrowings under the term loan credit agreement entered into on September 28, 2020 (the “New Term Loan Credit Agreement”) among the Company, the lenders from time to time party thereto, and Wells Fargo Bank, National Association, as the administrative agent, and to pay all related fees and expenses. (The New Term Loan Credit Agreement refinanced and replaced that certain Term Loan Credit Agreement, dated as of May 8, 2012 (as amended, restated, supplemented, or otherwise modified from time to time, the “Old Term Loan Credit Agreement”), among the Company, the lenders party thereto and Morgan Stanley Senior Funding, Inc., as the administrative agent.) Debt extinguishment charges totaling $9.1 million were recorded during the fourth quarter of 2021 in connection with the redemption in full of the Senior Notes due 2025 and the repayment in full of the outstanding borrowings under the New Term Loan Credit Agreement. The loss on debt extinguishment charges is included in Other, net on the Company’s Consolidated Statements of Operations.
Contractual coupon interest expense and accretion of fees for the New Senior Notes for the years ended December 31, 2023, 2022 and 2021 were $18.0 million and $0.6 million, $18.0 million and $0.6 million, and $4.3 million and $0.1 million, respectively.
Contractual coupon interest expense and accretion of discount and fees for the Senior Notes due 2025, which were redeemed in full during the fourth quarter of 2021 as described above, for the year ended December 31, 2021, was $13.3 million and $0.5 million, respectively.
Contractual coupon interest expense and accretion of discount and fees are included in Interest expense on the Company’s Consolidated Statements of Operations.
Revolving Credit Agreement
On September 23, 2022, the Company entered into the Third Amendment to the Second Amended and Restated Credit Agreement among the Company, certain of its subsidiaries as borrowers (together with the Company, the “Borrowers”), certain of its subsidiaries as guarantors, the lenders party thereto, and Wells Fargo Capital Finance, LLC, as the administrative agent (the “Agent”), which amended the Company’s existing Second Amended and Restated Credit Agreement, dated as of December 21, 2018 (as amended from time to time, the “Revolving Credit Agreement”).
Under the Revolving Credit Agreement, the lenders agree to make available a $350 million revolving credit facility to the Borrowers with a scheduled maturity date of September 23, 2027. The Company has the option to increase the total commitments under the facility by up to an additional $175 million, subject to certain conditions, including obtaining agreements from one or more lenders, whether or not party to the Revolving Credit Agreement, to provide such additional commitments. Availability under the Revolving Credit Agreement is based upon quarterly (or more frequent under certain circumstances) borrowing base certifications of the Borrowers’ eligible inventory, eligible leasing inventory and eligible accounts receivable, and is reduced by certain reserves in effect from time to time.
Subject to availability, the Revolving Credit Agreement provides for a letter of credit subfacility in the amount of $25 million, and allows for swingline loans in the amount of $35 million. Outstanding borrowings under the Revolving Credit Agreement bear interest at an annual rate, at the Borrowers’ election, equal to (i) adjusted term Secured Overnight Financing Rate plus a margin ranging from 1.25% to 1.75% or (ii) a base rate plus a margin ranging from 0.25% to 0.75%, in each case depending upon the monthly average excess availability under the Revolving Credit Agreement. The Borrowers are required to pay a monthly unused line fee equal to 0.20% times the average daily unused availability along with other customary fees and expenses of the Agent and the lenders.
The Revolving Credit Agreement is guaranteed by certain subsidiaries of the Company (the “Guarantors”) and is secured by substantially all personal property of the Borrowers and the Guarantors.
The Revolving Credit Agreement contains customary covenants limiting the ability of the Company and certain of its subsidiaries to, among other things, pay cash dividends, incur debt or liens, redeem or repurchase stock, enter into transactions with affiliates, merge, dissolve, repay subordinated indebtedness, make investments and dispose of assets. In addition, the Company will be required to maintain a minimum fixed charge coverage ratio of not less than 1.0 to 1.0 as of the end of any period of 12 fiscal months when excess availability under the Revolving Credit Agreement is less than the greater of (a) 10% of the lesser of (i) the total revolving commitments and (ii) the borrowing base (such lesser amount, the “Line Cap”) and (b) $25 million. As of December 31, 2023, the Company was in compliance with all covenants.
If availability under the Revolving Credit Agreement is less than the greater of (i) 10% of the Line Cap and (ii) $25 million for three consecutive business days, or if there exists an event of default, amounts in any of the Borrowers’ and the Guarantors’ deposit accounts (other than certain excluded accounts) will be transferred daily into a blocked account held by the Agent and applied to reduce the outstanding amounts under the facility.
The Revolving Credit Agreement contains customary events of default. If an event of default occurs and is continuing, the lenders may, among other things, require the immediate payment of all amounts outstanding and foreclose on collateral. In addition, in the case of an event of default arising from certain events of bankruptcy or insolvency, the lenders’ obligations under the Revolving Credit Agreement would automatically terminate, and all amounts outstanding under the Revolving Credit Agreement would automatically become due and payable.
The Company’s liquidity position, defined as cash on hand and available borrowing capacity on the Revolving Credit Agreement, amounted to $516.1 million as of December 31, 2023 and $401.2 million as of December 31, 2022.
During the year ended December 31, 2023, the Company had payments of principal of $104.2 million and borrowings of principal of $104.2 million under the Revolving Credit Agreement, and as of December 31, 2023, there were no amounts outstanding.
During the year ended December 31, 2022, the Company had net payments of principal of $130.6 million and net borrowings of principal of $97.6 million under the Revolving Credit Agreement, and as of December 31, 2022, there were no amounts outstanding.
Interest expense under the Revolving Credit Agreement for the years ended December 31, 2023, 2022, and 2021, was approximately $0.9 million, $1.7 million, and $0.6 million, respectively. Interest expense under the Revolving Credit Agreement is included in Interest expense on the Company’s Consolidated Statements of Operations.
New and Old Term Loan Credit Agreements
As described above, in October 2021, the Company used the net proceeds of the New Senior Notes and a portion of the $50 million draw from the increased capacity under the Revolving Credit Agreement to repay in full the $108.8 million of outstanding borrowings under the New Term Loan Credit Agreement. In addition to the full repayment during the fourth quarter, during the second quarter of 2021, the Company made principal payments totaling $30.0 million and recognized loss on debt extinguishment charges of approximately $0.5 million. The extinguishment charges are included in Other, net in the Consolidated Statements of Operations.
For the year ended December 31, 2021, under the New Term Loan Credit Agreement the Company paid interest of $3.9 million. For the year ended December 31, 2021, the Company incurred charges of $0.2 million for amortization of fees and original issuance discount, which are included in Interest expense in the Consolidated Statements of Operations.

Commodity Pricing Risk
As of December 31, 2023, the Company was party to commodity swap contracts for specific commodities with notional amounts of approximately $35.7 million. The Company uses commodity swap contracts to mitigate the risks associated with fluctuations in commodity prices impacting its cash flows related to inventory purchases from suppliers. The Company does not hedge all commodity price risk.
At inception, the Company designated the commodity swap contracts as cash flow hedges. The contracts mature at specified monthly settlement dates and will be recognized into earnings through November 2024. The effective portion of the hedging transaction is recognized in Accumulated Other Comprehensive Income (Loss) (“AOCI”) and transferred to earnings when the forecasted hedged transaction takes place or when the forecasted hedged transaction is no longer probable to occur.

Leases [Abstract]  
LEASES LEASES
Lessee Activities
The Company records a right-of-use ("ROU") asset and lease liability for substantially all leases for which it is a lessee, in accordance with ASC 842. Leases with an initial term of 12 months or less are not recorded on the balance sheet. The Company recognizes lease expense for leases on a straight-line basis over the lease term. At inception of a contract, the Company considers all relevant facts and circumstances to assess whether or not the contract represents a lease by determining whether or not the contract conveys the right to control the use of an identified asset, either explicit or implicit, for a period of time in exchange for consideration.
The Company leases certain industrial spaces, office space, land, and equipment. Some leases include one or more options to renew, with renewal terms that can extend the lease term from generally one to 5 years. The exercise of lease renewal options is at the Company’s sole discretion, and are included in the lease term only to the extent such renewal options are reasonably certain of being exercised upon lease commencement. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term unless there is a transfer of title or purchase option reasonably certain of exercise. Leased assets obtained in exchange for new operating lease liabilities during the year ended December 31, 2023 and December 31, 2022 were approximately $13.4 million and $16.6 million, respectively. As of December 31, 2023, obligations related to leases that the Company has executed but have not yet commenced were insignificant.
During the year ended December 31, 2022, the Company entered into sale-leaseback-sublease transactions. Such contracts were entered into in contemplation of each other and are thus recorded on a net basis. The net revenue from these contracts was insignificant for the year ended December 31, 2023. In addition, certain of the transactions occurred with a related party—such transactions were at market value and arm’s length.

Lessor and Sublessor Activities
The Company leases dry van trailers to customers under full-service lease agreements and operating lease agreements. At the inception of a contract, in accordance with the applicable accounting guidance (ASC 842, Leases) the Company considers whether the arrangement contains a lease and, as applicable, performs the required lease classification tests. The Company, as a lessor, has no sales-type or direct financing lease arrangements as of December 31, 2023.
The Company’s full-service lease agreements are an integrated service that include lease component amounts related to the use of the trailer, as well as non-lease components for preventative maintenance, certain repairs as defined in the related agreement, and ad valorem taxes. In accordance with the applicable accounting guidance (ASC 842, Leases), the Company has elected to combine lease and non-lease components when reporting revenue for the full-service underlying class of leased assets.
Initial lease terms are generally three to five years. Certain of the Company’s leases provide customers with renewal options that provide the ability to extend the lease term for a period of generally one to five years. In addition, some leases include options for the customer to purchase the trailers at fair market value, as determined by the Company at or near the end of the lease. The Company’s lease agreements generally do not have residual value guarantees nor permit customers to terminate the lease agreements prior to natural expiration. As stipulated in the lease agreements, the Company may receive reimbursements from customers for certain damage or required repairs to the trailers. We expect to derive an immaterial amount from the underlying assets following the end of the respective lease terms.
During the year ended December 31, 2022, the Company entered into sale-leaseback-sublease transactions. Such contracts were entered into in contemplation of each other and are thus recorded on a net basis. The net revenue from these contracts was insignificant for all periods presented but such revenue is included in the tables below.

FAIR VALUE MEASUREMENTS
 12 Months Ended
Dec. 31, 2023
Fair Value Disclosures [Abstract]  
FAIR VALUE MEASUREMENTS FAIR VALUE MEASUREMENTS
The Company’s fair value measurements are based upon a three-level valuation hierarchy. These valuation techniques are based upon the transparency of inputs (observable and unobservable) to the valuation of an asset or liability as of the measurement date. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy:
▪Level 1 — Valuation is based on quoted prices for identical assets or liabilities in active markets;
▪Level 2 — Valuation is based on quoted prices for similar assets or liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for the full term of the financial instrument; and
▪Level 3 — Valuation is based upon other unobservable inputs that are significant to the fair value measurement.
Recurring Fair Value Measurements
The Company maintains a non-qualified deferred compensation plan which is offered to senior management and other key employees. The amount owed to participants is an unfunded and unsecured general obligation of the Company. Participants are offered various investment options with which to invest the amount owed to them, and the plan administrator maintains a record of the liability owed to participants by investment. To minimize the impact of the change in market value of this liability, the Company has elected to purchase a separate portfolio of investments through the plan administrator similar to those chosen by the participant.

Estimated Fair Value of Debt
The estimated fair value of debt at December 31, 2023 consists of the Senior Notes due 2028 (see Note 10). The interest rates on the Company’s borrowings under the Revolving Credit Agreement are adjusted regularly to reflect current market rates and thus carrying value approximates fair value for any borrowings. The fair value of the Senior Notes due 2028 as of December 31, 2023 and 2022 are based upon third party pricing sources, which generally do not represent daily market activity or represent data obtained from an exchange, and are classified as Level 2.

Commitments and Contingencies Disclosure [Abstract]  
COMMITMENTS AND CONTINGENCIES COMMITMENTS AND CONTINGENCIES
a.    Litigation
As of December 31, 2023, the Company was named as a defendant or was otherwise involved in numerous legal proceedings and governmental examinations, including class action lawsuits, in connection with the conduct of its business activities, in various jurisdictions, both in the United States and internationally. Accrual for losses have been recorded for those matters deemed both probable and reasonably estimated. On the basis of information currently available to it, management does not believe that existing proceedings and investigations will have a material impact on our consolidated financial condition or liquidity if determined in a manner adverse to the Company. However, such matters are unpredictable, and we could incur judgments or enter into settlements for current or future claims that could materially and adversely affect our financial statements. Costs associated with the litigation and settlements of legal matters are reported within General and administrative expenses in the Consolidated Statements of Operations.
Legal Matter Estimated Liability
As of December 31, 2023, the Company was named as a defendant in California state court in two purported class action lawsuits, alleging wage and hour claims under California-specific employment laws (collectively, the “Matters”). The defense of both lawsuits is being handled in conjunction with one another. During the three months ended March 31, 2023, in accordance with ASC 450, the Company concluded a liability related to the Matters was probable and estimable. As such, an estimated liability of $3.0 million is included in General & administrative expenses in the Consolidated Statements of Operations for the year ended December 31, 2023. During the second quarter of 2023, the Company reached an agreement to resolve the Matters via settlement for an amount materially consistent with the estimated liability. The settlement proceeds will be paid in the first quarter of 2024.
Environmental Disputes
In August 2014, the Company received notice as a potentially responsible party (“PRP”) by the South Carolina Department of Health and Environmental Control (the “DHEC”) pertaining to the Philip Services Site located in Rock Hill, South Carolina pursuant to the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) and corresponding South Carolina statutes. PRPs include parties identified through manifest records as having contributed to deliveries of hazardous substances to the Philip Services Site between 1979 and 1999. The DHEC’s allegation that the Company was a PRP arises out of four manifest entries in 1989 under the name of a company unaffiliated with Wabash National Corporation (or any of its former or current subsidiaries) that purport to be delivering a de minimis amount of hazardous waste to the Philip Services Site “c/o Wabash National Corporation.” As such, the Philip Services Site PRP Group (the “PRP Group”) notified Wabash in August 2014 that it was offering the Company the opportunity to resolve any liabilities associated with the Philip Services Site by entering into a Cash Out and Reopener Settlement Agreement (the “Settlement Agreement”) with the PRP Group, as well as a Consent Decree with the DHEC. The Company has accepted the offer from the PRP Group to enter into the Settlement Agreement and Consent Decree, while reserving its rights to contest its liability for any deliveries of hazardous materials to the Philips Services Site. The requested settlement payment is immaterial to the Company’s financial condition and results of operations, and as a result, if the Settlement Agreement and Consent Decree are finalized, the payment to be made by the Company thereunder is not expected to have a material adverse effect on the Company’s financial condition or results of operations.

On November 13, 2019, the Company received a notice that it was considered one of several PRPs by the Indiana Department of Environmental Management (“IDEM”) under CERCLA and state law related to substances found in soil and groundwater at a property located at 817 South Earl Avenue, Lafayette, Indiana (the “Site”). The Company has never owned or operated the Site, but the Site is near certain of the Company’s owned properties. In 2020, the Company agreed to implement a limited work plan to further investigate the source of the contamination at the Site and worked with IDEM and other PRPs to finalize the terms of the work plan. The Company submitted its initial site investigation report to IDEM during the third quarter of 2020, indicating that the data collected by the Company’s consultant confirmed that the Company’s properties are not the source of contamination at the Site. In December 2021, after completing further groundwater sampling work, the Company submitted to IDEM a supplemental written report, which again stated that the Company is not a responsible party and the Company’s properties are not a source of any contamination. In June 2022, the Company and other PRPs finalized Work Plan Addendum No. 3, which provided for additional groundwater sampling on another PRP property. The Company completed all additional sampling between the second quarter and fourth quarter of 2023, and all available information establishes there is no source of any contamination on the Company’s owned properties. As of December 31, 2023, based on the information available, the Company does not expect this matter to have a material adverse effect on its financial condition or results of operations.
b.    Environmental Litigation Commitments and Contingencies
The Company generates and handles certain material, wastes and emissions in the normal course of operations that are subject to various and evolving federal, state and local environmental laws and regulations.
The Company assesses its environmental liabilities on an on-going basis by evaluating currently available facts, existing technology, presently enacted laws and regulations as well as experience in past treatment and remediation efforts. Based on these evaluations, the Company estimates a lower and upper range for treatment and remediation efforts and recognizes a liability for such probable costs based on the information available at the time. As of December 31, 2023, the Company had reserved an insignificant amount for estimated remediation costs for activities at existing and former properties which are recorded within Other accrued liabilities on the Consolidated Balance Sheets.
c.    Letters of Credit
As of December 31, 2023, the Company had standby letters of credit totaling $6.0 million issued in connection with workers compensation claims and surety bonds.
d. Purchase Commitments
The Company has $35.7 million in purchase commitments at December 2023 for various raw material commodities, including aluminum, steel, nickel, and polyethylene, as well as other raw material components which are within normal production requirements.
e.    Chassis Converter Pool Agreements
The Company obtains vehicle chassis for its specialized vehicle products directly from the chassis manufacturers under converter pool agreements. Chassis are obtained from the manufacturers based on orders from customers, and in some cases, for unallocated orders. The agreements generally state that the manufacturer will provide a supply of chassis to be maintained at the Company’s facilities with the condition that we will store such chassis and will not move, sell, or otherwise dispose of such chassis except under the terms of the agreement. In addition, the manufacturer typically retains the sole authority to authorize commencement of work on the chassis and to make certain other decisions with respect to the chassis including the terms and pricing of sales of the chassis to the manufacturer’s dealers. The manufacturer also does not transfer the certificate of origin to the Company nor permit the Company to sell or transfer the chassis to anyone other than the manufacturer (for ultimate resale to a dealer). Although the Company is party to related finance agreements with manufacturers, the Company has not historically settled, nor expects to in the future settle, any related obligations in cash. Instead, the obligation is settled by the manufacturer upon reassignment of the chassis to an accepted dealer, and the dealer is invoiced for the chassis by the manufacturer. Accordingly, as of December 31, 2023, the Company’s outstanding chassis converter pool with the manufacturer totaled $27.3 million and has included this financing agreement on the Company’s Consolidated Balance Sheets within Prepaid expenses and other and Other accrued liabilities. All other chassis programs are handled as consigned inventory belonging to the manufacturer and totaled approximately $0.9 million. Under these agreements, if the chassis is not delivered to a customer within a specified time frame, the Company is required to pay a finance or storage charge on the chassis. Additionally, the Company receives finance support funds from manufacturers when the chassis are assigned into the Company’s chassis pool. Typically, chassis are converted and delivered to customers within 90 days of the receipt of the chassis by the Company.

Earnings Per Share [Abstract]  
NET INCOME PER SHARE OF COMMON STOCK NET INCOME PER SHARE OF COMMON STOCK
Basic earnings per share is calculated based on the weighted average number of common shares outstanding during the period. Diluted earnings per share is determined based on the weighted average number of common shares outstanding during the period combined with the incremental average common shares that would have been outstanding assuming the conversion of all potentially dilutive common shares into common shares as of the earliest date possible. The calculation of basic and diluted net income attributable to common stockholders per share is determined using net income applicable to common stockholders as the numerator and the number of shares included in the denominator as shown below (in thousands, except per share amounts).

Share-Based Payment Arrangement, Noncash Expense [Abstract]  
STOCK-BASED COMPENSATION STOCK-BASED COMPENSATION
On May 18, 2017, the shareholders of the Company approved the 2017 Omnibus Incentive Plan (the “2017 Incentive Plan”) which authorizes 3,150,000 shares for issuance under the plan. Awards granted under the 2017 Incentive Plan may be in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, other share-based awards, and cash awards to directors, officers, and other eligible employees of the Company.
The Company recognizes all share-based awards to eligible employees based upon their grant date fair value. The Company’s policy is to recognize expense for awards that have service conditions only subject to graded vesting using the straight-line attribution method. In addition, the Company’s policy is to estimate expected forfeitures on share-based awards. Total stock-based compensation expense was $11.8 million, $9.7 million, and $7.1 million in the years ended December 31, 2023, 2022 and 2021, respectively, and is included in Cost of sales, General and administrative expenses, and Selling expenses within the Consolidated Statements of Operations. The amount of compensation cost related to non-vested restricted stock not yet recognized was approximately $13.5 million at December 31, 2023, for which the weighted average remaining life was approximately 1.8 years. There was no compensation cost related to non-vested stock options not yet recognized at December 31, 2023.
Restricted Stock
Restricted stock awards vest over a period of one to three years and may be based on the achievement of specific financial performance metrics and market conditions. Awards based strictly on time-based vesting and those awards with performance metrics are valued at the market price on the date of grant. The fair values of the awards that contain market conditions are estimated using a Monte Carlo simulation approach in a risk-neutral framework to model future stock price movements based upon historical volatility, risk-free rates of return, and correlation matrix. Restricted stock awards are generally forfeitable in the event of terminated employment prior to vesting.

The total fair value of restricted stock that vested during 2023, 2022, and 2021 was approximately $25.1 million, $8.9 million, and $5.0 million, respectively.
Stock Options
Stock options are awarded with an exercise price equal to the market price of the underlying stock on the date of grant, become fully exercisable three years after the date of grant, and expire ten years after the date of grant. No stock options have been granted by the Company since February 2015.

Deferred Taxes
The Company’s deferred income taxes are primarily due to temporary differences between financial and income tax reporting for incentive compensation, depreciation of property, plant and equipment, amortization of intangibles, and other accrued liabilities.
Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Companies are required to assess whether valuation allowances should be established against their deferred tax assets based on the consideration of all available evidence, both positive and negative, using a “more likely than not” standard. In making such judgments, significant weight is given to evidence that can be objectively verified.
The Company assesses, on a quarterly basis, the realizability of its deferred tax assets by evaluating all available evidence, both positive and negative, including: (1) the cumulative results of operations in recent years, (2) the nature of recent losses, if applicable, (3) estimates of future taxable income, (4) the length of net operating loss carryforwards (“NOLs”) and (5) the uncertainty associated with a possible change in ownership, which imposes an annual limitation on the use of these carryforwards.
As of December 31, 2023 and 2022, the Company retained a valuation allowance of $0.7 million and $0.8 million, respectively, against deferred tax assets related to various state and local NOLs that are subject to restrictive rules for future utilization.
As of December 31, 2023 and 2022, the Company had no U.S. federal tax NOLs. The Company incurred a net loss in 2020 and fully utilized that loss in carrybacks. The Company has various multi-state income tax NOLs aggregating approximately $47.5 million which will expire between 2024 and 2043, if unused.

The Company’s policy with respect to interest and penalties associated with reserves or allowances for uncertain tax positions is to classify such interest and penalties in Income tax expense (benefit) on the Consolidated Statements of Operations. As of December 31, 2023 and 2022, the total amount of unrecognized income tax benefits, which are included in either Other noncurrent liabilities or Deferred income taxes in the Company’s Consolidated Balance Sheets, was approximately $4.8 million and $2.4 million, respectively, including interest and penalties, all of which, if recognized, would impact the effective income tax rate of the Company. As of December 31, 2023 and 2022, the Company had recorded a total of $0.9 million and $0.9 million, respectively, of accrued interest and penalties related to uncertain tax positions. The Company expects no significant changes to the facts and circumstances underlying its reserves and allowances for uncertain income tax positions as reasonably possible during the next 12 months. As of December 31, 2023, the Company is subject to unexpired statutes of limitation for U.S. federal income taxes for the years 2020 through 2022. The Company is also subject to unexpired statutes of limitation for Indiana state income taxes for the years 2020 through 2022.

Segment Reporting
Based on how the Chief Operating Decision Maker (“CODM”) manages the business, allocates resources, makes operating decisions, and evaluates operating performance, the Company manages its business in two operating and reportable segments: Transportation Solutions and Parts & Services.
Additional information related to the composition of each segment is included below.
▪Transportation Solutions (“TS”): The TS segment comprises the design and manufacturing operations for the Company’s transportation-related equipment and products. This includes dry and refrigerated van trailers, platform trailers, and the Company’s wood flooring production facility. The Company’s EcoNex™ products, which are under the Company’s Acutherm™ portfolio of solutions designed for intelligent thermal management, are also reported in the TS segment. In addition, the TS segment includes tank trailers and truck-mounted tanks. Finally, truck-mounted dry and refrigerated bodies and service and stake bodies are also in the TS segment.
▪Parts & Services (“P&S”): The P&S segment is comprised of the Company’s parts and services businesses as well as the upfitting component of our truck bodies business. In addition, the Company’s Composites business, which focuses on the use of DuraPlate® composite panels beyond the semi-trailer market, is also part of the P&S segment. This segment also includes the Wabash Parts LLC and Linq Venture Holdings LLC entities we created with our partners during the second quarter of 2022 and the fourth quarter of 2023 as further described in Note 6. Our Trailers as a Service (TAAS) initiatives are included in the P&S segment as well. Finally, the P&S segment includes the Company’s Engineered Products business, which manufactures stainless-steel storage tanks and silos, mixers, and processors for a variety of end markets. Growing and expanding the parts and services businesses is a key strategic initiative for the Company moving forward.
The accounting policies of the TS and P&S segments are the same as those described in the summary of significant accounting policies except that the Company evaluates segment performance based on income (loss) from operations. The Company has not allocated certain corporate related administrative costs, interest, and income taxes included in the corporate and eliminations segment to the Company’s other reportable segments. The Company accounts for intersegment sales and transfers at cost. Segment assets are not presented as it is not a measure reviewed by the CODM in allocating resources and assessing performance.

IMPAIRMENT, DIVESTITURES AND SALES OF PROPERTY, PLANT, AND EQUIPMENT DIVESTITURES, AND SALES OF PROPERTY, PLANT, AND EQUIPMENT
During the first quarter of 2022, the Company impaired approximately $1.0 million of construction-in-progress projects that were no longer expected to be completed. In addition, the Company sold a building (and the related land) for net proceeds of $1.1 million. A gain on sale of approximately $0.7 million was recognized as part of the sale. The impairment and gain on sale are included in Impairment and other, net in the Consolidated Statements of Operations.
During the second quarter of 2021, the Company sold its Extract Technology® (“Extract”) business that manufactured stainless steel isolators and downflow booths, as well as custom-fabricated equipment, including workstations and drum booths for the pharmaceutical, fine chemical, biotech, and nuclear end markets. Proceeds of the sale, net of transaction costs and cash divested, totaled approximately $20.8 million. Prior to the sale, Extract was an operating unit within the historical DPG reporting segment. A gain on sale of approximately $1.9 million was recognized in connection with the divestiture, and a portion of the net proceeds from the sale were used to pay down outstanding principal under the New Term Loan Credit Agreement as further described in Note 10. The gain on sale is included in Impairment and other, net in the Consolidated Statements of Operations. In accordance with the relevant accounting guidance, as part of the sale the Company allocated $11.1 million of goodwill based upon the relative fair value of the Extract operating unit compared to the historical DPG reporting unit as a whole. This goodwill, along with net intangible assets of approximately $1.3 million, were included in the carrying value of the disposed assets and the resulting gain recognized in connection with the sale.
During the first quarter of 2021, the Company impaired unused and obsolete property, plant, and equipment assets totaling approximately $0.8 million. The impairment charges are included in Impairment and other, net in the Consolidated Statements of Operations.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)
 12 Months Ended
Dec. 31, 2023
Accounting Policies [Abstract]  
Basis of Consolidation The consolidated financial statements reflect the accounts of the Company and its wholly-owned and majority-owned subsidiaries. All significant intercompany profits, transactions, and balances have been eliminated in consolidation.
Reclassifications Certain prior period amounts have been reclassified to conform to the current year presentation.
Use of Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that directly affect the amounts reported in its consolidated financial statements and accompanying notes. Actual results could differ from these estimates.
Cash and Cash Equivalents Cash and cash equivalents include all highly liquid investments with a maturity of three months or less at the time of purchase.
Accounts Receivable Accounts receivable are shown net of expected losses and primarily include trade receivables. The Company records expected losses for customers based upon a variety of factors including the Company’s historical collection experience, the length of time the account has been outstanding, and the financial condition of the customer. If the circumstances related to specific customers were to change, the Company’s estimates of expected losses with respect to the collectability of the related accounts could be further adjusted. The Company’s policy is to write-off receivables when they are determined to be uncollectible. Expected losses are charged to General and administrative expenses and Selling expenses in the Consolidated Statements of Operations.
Inventories Inventories are stated at the lower of cost, determined on either the first-in, first-out or average cost method, or net realizable value. The cost of manufactured inventory includes raw material, labor and overhead.
Prepaid Expenses and Other Chassis converter pool agreements represent chassis transferred to the Company on a restricted basis by the manufacturer, who retains the sole authority to authorize commencement of work on the chassis and to make certain other decisions with respect to the chassis including the terms and pricing of sales to the manufacturer’s dealers. As further described in Note 11, commodity swap contracts relate to our hedging activities (that are in an asset position) to mitigate the risks associated with fluctuations in commodity prices. Insurance premiums and maintenance/subscription agreements are charged to expense over the contractual life, which is generally one year or less. Other items primarily consist of investments held by the Company’s captive insurance subsidiary and other various prepaid and other assets.
Property, Plant and Equipment Property, plant, and equipment are recorded at cost, net of accumulated depreciation. Maintenance and repairs are charged to expense as incurred, while expenditures that extend the useful life of an asset are capitalized. Depreciation is recorded using the straight-line method over the estimated useful lives of the depreciable assets. The estimated useful lives are up to 33 years for buildings and building improvements and range from three to ten years for machinery and equipment.
Goodwill Goodwill represents the excess purchase price over fair value of the net assets acquired. The Company determines its reporting units at the individual operating segment level, or one level below, when there is discrete financial information available that is regularly reviewed by segment management for evaluating operating results. The Company reviews goodwill for impairment, at the reporting unit level, annually on October 1 and whenever events or changes in circumstances indicate its carrying value may not be recoverable. In accordance with ASC 350, Intangibles - Goodwill and Other, goodwill is reviewed for impairment utilizing either a qualitative assessment or a quantitative process.
The Company has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. An entity has an unconditional option to bypass the qualitative assessment in any period and proceed directly to performing the quantitative impairment test, which is the option the Company has historically chosen.
For reporting units in which the Company performs the quantitative analysis, the Company compares the carrying value, including goodwill, of each reporting unit with its estimated fair value. If the fair value of the reporting unit exceeds its carrying value, the goodwill is not considered impaired. If the carrying value is greater than the fair value, the difference is recognized as an impairment loss charged to the reporting unit. After an impairment loss is recognized, the adjusted carrying amount of goodwill shall be its new accounting basis.
As of December 31, 2023, goodwill allocated to the Transportation Solutions (“TS”) and Parts & Services (“P&S”) segments was approximately $120.5 million and $67.9 million, respectively.
For the 2023 annual goodwill impairment test conducted as of October 1st, 2023, the Company chose to evaluate qualitative factors to determine if it was more likely than not that the fair value of the TS and P&S reporting units were less than their respective carrying amounts. In accordance with the relevant accounting guidance, in order to perform the qualitative assessment, the Company considered many factors including, but not limited to, general economic conditions, industry and market conditions, financial performance and key business drivers, future operating plans, and potential changes to significant assumptions used in the most recent quantitative fair value analysis for each reporting unit (which was conducted in connection with the Company’s segment realignment beginning in September 2021 as further described below). Based on the analysis of the factors and considerations described above, the Company concluded that it was more likely than not that the fair value of each reporting unit continued to be greater than the respective carrying value. Therefore, no impairment charges were recorded and a quantitative analysis was not performed.
During the fourth quarters of 2022 and 2021, the Company completed its annual goodwill impairment test using the qualitative assessment. Based on all assessments performed, the Company believed it was more likely than not that the fair value of its reporting units were greater than their carrying amount and no additional impairment of goodwill was recognized.
In connection with the Company’s segment realignment beginning in September 2021 described in greater detail below, the Company performed a quantitative assessment for each reporting unit utilizing a combination of the income and market approaches, the results of which were weighted evenly. No impairment was indicated in either annual test as the fair value of each reporting unit exceeded its respective carrying value.
Long-Lived Assets Long-lived assets, consisting primarily of intangible assets and property, plant, and equipment, are reviewed for impairment whenever facts and circumstances indicate that the carrying amount may not be recoverable. Specifically, this process involves comparing an asset’s carrying value to the estimated undiscounted future cash flows the asset is expected to generate over its remaining life. If this process were to result in the conclusion that the carrying value of a long-lived asset would not be recoverable, a write-down of the asset to fair value would be recorded through a charge to operations. Fair value is determined based upon discounted cash flows or appraisals as appropriate.
During the first quarter of 2022, the Company impaired approximately $1.0 million of construction-in-progress projects that were no longer expected to be completed.
Other Assets The Company capitalizes the cost of computer software developed or obtained for internal use. Capitalized software is amortized using the straight-line method over three to seven years.
Warranties The Company offers a limited warranty for its products with a coverage period that ranges between one and five years, except that the coverage period for DuraPlate® trailer panels is ten years. The Company passes through component manufacturers’ warranties to our customers. The Company’s policy is to accrue the estimated cost of warranty coverage at the time of the sale.
Self Insured Liabilities The Company is self-insured up to specified limits for medical and workers’ compensation coverage. The self-insurance reserves have been recorded to reflect the undiscounted estimated liabilities, including claims incurred but not reported, as well as catastrophic claims as appropriate.
Income Taxes The Company determines its provision or benefit for income taxes under the asset and liability method. The asset and liability method measures the expected tax impact at current enacted rates of future taxable income or deductions resulting from differences in the tax and financial reporting basis of assets and liabilities reflected in the Consolidated Balance Sheets. Future tax benefits of tax losses and credit carryforwards are recognized as deferred tax assets. Deferred tax assets are reduced by a valuation allowance to the extent management determines that it is more-likely-than-not the Company would not realize the value of these assets.
The Company accounts for income tax contingencies by prescribing a “more-likely-than-not” recognition threshold that a tax position is required to meet before being recognized in the financial statements.
Used Trailer Trade Commitments The Company may accept trade-in of used trailers when a customer enters into a contract to purchase a new trailer. However, in the contracts for the sale of the new trailers, there is no commitment to repurchase that trailer or a similar trailer in the future. The Company had $0.5 million and no outstanding trade commitments as of December 31, 2023 and December 31, 2022, respectively. On occasion, the amount of the trade allowance provided for in the used trailer commitments, or cost, may exceed the net realizable value of the underlying used trailer. In these instances, the Company’s policy is to recognize the loss related to these commitments at the time the new trailer revenue is recognized. Net realizable value of used trailers is measured considering market sales data for comparable types of trailers.
Concentration of Credit Risk Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash, cash equivalents, and customer receivables. We place our cash and cash equivalents with high quality financial institutions. Generally, we do not require collateral or other security to support customer receivables.
Research and Development Research and development expenses are charged to Cost of sales and General and administrative expenses in the Consolidated Statements of Operations as incurred
New Accounting Pronouncements
In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (“ASU”) No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses, allowing financial statement users to better understand the components of a segment's profit or loss to assess potential future cash flows for each reportable segment and the entity as a whole. The amendments expand a public entity's segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker ("CODM"), clarifying when an entity may report one or more additional measures to assess segment performance, requiring enhanced interim disclosures, providing new disclosure requirements for entities with a single reportable segment, and requiring other new disclosures. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and early adoption is permitted. Although the ASU only requires additional disclosures about the Company's operating segments, the Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which is intended to enhance the transparency, decision usefulness and effectiveness of income tax disclosures. The amendments in this ASU require a public entity to disclose a tabular tax rate reconciliation, using both percentages and currency, with specific categories. A public entity is also required to provide a qualitative description of the states and local jurisdictions that make up the majority of the effect of the state and local income tax category and the net amount of income taxes paid, disaggregated by federal, state and foreign taxes and also disaggregated by individual jurisdictions. The amendments also remove certain disclosures that are no longer considered cost beneficial. The amendments are effective prospectively for annual periods beginning after December 15, 2024, and early adoption and retrospective application are permitted. Although the ASU only modifies the Company's required income tax disclosures, the Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements.
Revenue Recognition
The Company recognizes revenue from the sale of its products when obligations under the terms of a contract with our customers are satisfied; this occurs with the transfer of control of our products and replacement parts or throughout the completion of service work. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring promised goods or services to a customer and excludes all taxes collected from the customer. Shipping and handling fees are included in Net sales and the associated costs are included in Cost of sales in the Consolidated Statements of Operations. For shipping and handling costs that take place after the transfer of control, the Company applies the practical expedient and treats it as a fulfillment cost. Incidental items that are immaterial in the context of the contract are recognized as expense. For performance obligations satisfied over time, which includes service work whereby the customer simultaneously receives and consumes the benefits provided, and also included certain equipment-related sales within our Parts & Services reportable segment prior to the sale of our Extract Technology® business during the second quarter of 2021 that had no alternative use and contained an enforceable right to payment, the Company recognizes revenue on the basis of the Company’s efforts or inputs to the satisfaction of these performance obligations, measured by actual total cost incurred to the total estimated costs for each project. Total revenue recognized over time was not material to the consolidated financial statements for all periods presented.
The Company has identified three separate and distinct performance obligations: (1) the sale of a trailer or equipment, (2) the sale of replacement parts, and (3) service work. For trailer, truck body, equipment, and replacement part sales, control is transferred and revenue is recognized from the sale upon shipment to or pick up by the customer in accordance with the contract terms. The Company does not have any material extended payment terms as payment is received shortly after the point of sale. Accounts receivable are recorded when the right to consideration becomes unconditional. The Company does have customers who pay for the product prior to the transfer of control, which is recorded as customer deposits in Other accrued liabilities as shown in Note 9. Customer deposits are recognized as revenue when the Company performs its obligations under the contract and transfers control of the product.
