Commitments and Contingencies Disclosure [Abstract] |
COMMITMENTS AND CONTINGENCIES | COMMITMENTS AND CONTINGENCIES Litigation As of March 31, 2026, 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. Guarantees and Indemnifications On February 26, 2026, the Company completed a sale transaction for dry van trailers with McKinney Vehicle Services, Inc. As part of the transaction, FreightVana Logistics, Inc. ("FreightVana"), will lease the equipment back from McKinney Vehicle Services, Inc. for six years, supported by a 24-month limited guaranty from the Company. The $6.7 million proceeds reflected the standalone fair value of the assets sold and no allocation was made for the guaranty. The estimated $0.5 million fair value of the guaranty was expensed to General and administrative expenses in the Condensed Consolidated Statements of Operations. 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 March 31, 2026, 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. On December 1, 2025, the Company received a notice that it was considered one of several PRP’s by the Environmental Protection Agency (“EPA”) under CERCLA pertaining to the Motorola, Inc. 52nd Street Superfund Site in Maricopa, Arizona. The Superfund Site is divided into three operable units (“OUs”). The EPA’s allegation that the Company was a PRP arises out of the Company’s acquisition of a former branch facility located approximately five miles from the original Superfund Site. The Company acquired this facility in 1997, operated the facility until 2000, and sold the facility to a third party in 2002. In June 2010, the Company was contacted by the Roosevelt Irrigation District (“RID”) informing it that the Arizona Department of Environmental Quality (“ADEQ”) had approved a remediation plan in excess of $100 million for the RID portion of the Superfund Site, and demanded that the Company contribute to the cost of the plan or be named as a defendant in a CERCLA action to be filed in July 2010. The Company initiated settlement discussions with the RID and the ADEQ in July 2010 to provide a full release from the RID, and a covenant not-to-sue and contribution protection regarding the former branch property from the ADEQ, in exchange for payment from the Company. In May 2016, the Company, the ADEQ and the RID executed the originally proposed settlement agreements and, following a statutorily required 30-day public comment period, the settlement agreements were finalized and the Company paid $0.2 million, which had been accrued by the Company since 2010. ADEQ is the lead agency for OU1 and OU2 of the Superfund Site, while EPA is the lead agency for OU3. In October 2025, EPA finalized a Record of Decision for a final remedy for OU3, in which it approved a remediation plan for targeted in-situ injection and monitored attenuation, with an estimated cost of $12.9 million as to all relevant parties. As of March 31, 2026, 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 March 31, 2026, the Company’s outstanding chassis converter pool with the manufacturer totaled $46.3 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.
