Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Litigation As of September 30, 2025, 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 in accordance with GAAP. Based on the information currently available, 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 except as otherwise described below. 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 Condensed Consolidated Statements of Operations. Product Liability Claims The Company is and has been, and may in the future be, subject to product liability claims and litigation incidental to the Company’s normal operating activities. On October 9, 2025, the Company finalized a settlement (the “Settlement”) with the plaintiffs in a lawsuit, Eileen Williams, Elizabeth Perkins, et al. v. Wabash National Corporation, et al., filed in the Circuit Court of the City of St. Louis, Missouri (the “Product Liability Matter”), in which the Company was named as co-defendant. The Product Liability Matter related to a vehicle accident that resulted in two fatalities following a rear-end collision by a passenger vehicle with an unobstructed view which struck the back of a nearly stopped tractor-trailer owned and operated by co-defendant GDS Express Inc. The Settlement will be covered by insurance, other than a $30 million contribution to be made by the Company. The Company, after taking into account the insurance coverage, recognized a $81.2 million reduction to the charge taken in the third quarter of 2024, as previously reported within General and Administrative expenses in the Company’s Condensed Consolidated Statements of Operation. This reduction reflects the reversal of an (1) insurance receivable of $11.5 million included in Other assets (the “Insurance Receivable”) and (2) aggregate liability for the Product Liability Matter of $122.7 million included in Other non-current liabilities (the “Matter Liability”), each, as previously reflected in the Company’s Condensed Consolidated Balance Sheet as of June 30, 2025. As of the nine months ended September 30, 2025, the Company has recognized a $418.6 million reduction in charges related to the Product Liability Matter in the Company’s Condensed Consolidated Statements of Operation within General and Administrative expenses. The Company’s Condensed Consolidated Balance Sheet as of September 30, 2025, includes a current insurance receivable of $47 million recorded in Prepaid expenses and other and $77 million recorded in Other accrued liabilities related to the Settlement. The evidence in the Product Liability Matter was undisputed that the trailer fully complied with all applicable regulations. Despite precedent to the contrary, the jury was prevented from hearing critical evidence in the case, including that the driver’s blood alcohol level was over the legal limit at the time of the accident and the fact that neither the driver nor the passenger was wearing a seatbelt. As previously disclosed in the Company’s filings with the SEC, on September 5, 2024, a jury awarded compensatory damages of $12 million and punitive damages of $450 million against the Company in the Product Liability Matter. On November 22, 2024, applying an offset related to the plaintiff’s settlement with a separate defendant, the Circuit Court entered judgment in the Product Liability Matter consisting of compensatory damages of $11.5 million and punitive damages of $450 million. On March 20, 2025, the Circuit Court determined that the punitive damage award in the Product Liability Matter did not comport with the Company’s constitutional rights. Accordingly, the Circuit Court ordered the punitive damages award reduced to $108 million with the compensatory damages award remaining at $11.5 million (collectively, the “Adjusted Award”). Based on the Adjusted Award, in the first quarter of 2025, the Company recognized a $342 million reduction to the $461.5 million charge taken in the third quarter of 2024. During the second quarter of 2025, the Company accrued a $3.2 million contingent liability for penalty costs using an annual interest rate based on the amended judgment. As of June 30, 2025, the Company (1) recognized the Matter Liability and (2) included the $342 million adjustment and a total of $4.6 million bond and contingent penalty interest expenses in the Company’s Condensed Consolidated Statements of Operation within General and Administrative expenses for the period ended June 30, 2025. The Settlement does not constitute an admission of liability or wrongdoing by the Company. 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 and submitted supplemental reports to IDEM as of the first quarter of 2024. All available information and reports establish there is no source of any contamination on the Company’s owned properties. As of September 30, 2025, 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. 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 September 30, 2025, the Company’s outstanding chassis converter pool with the manufacturer totaled $70.3 million and has included this financing agreement on the Company’s Condensed Consolidated Balance Sheets within Other accrued liabilities. Typically, chassis are converted and delivered to customers within 90 days of the receipt of the chassis by the Company.
