Non-GAAP adjusted earnings per diluted share for the third quarter of 2024 and 2025 exclude non-cash expense adjustments for a lawsuit, the Product Liability Matter, described below.

~~EXHIBIT~~Challenging ~~INDEX~~market conditions persisted through the quarter, driving softer demand and expected revenue below the low end of our guidance range.

1 Free cash flow is defined as net cash (used in) provided by operating activities minus cash payments for capital expenditures minus expenditures for revenue generating assets.

Non-GAAP Measures

In addition to disclosing financial results calculated in accordance with United States generally accepted accounting principles (“GAAP”), the financial information included in this Form 8-K contains non-GAAP financial measures. These non-GAAP measures should not be considered a substitute for, or superior to, financial measures and results calculated in accordance with GAAP, including net (loss) income, and reconciliations to GAAP financial statements should be carefully evaluated.

Adjusted diluted (loss) earnings per share reflect an adjustment for the Product Liability Matter and the related tax effect of that adjustment. Management believes providing adjusted measures and excluding certain items facilitates comparisons to the Company’s prior year periods and, when combined with the GAAP presentation of diluted net (loss) income per share, is beneficial to an investor’s understanding of the Company’s performance. A reconciliation of adjusted diluted (loss) earnings per share to diluted earnings (loss) per share, the most comparable GAAP financial measures, are included in the tables below.

Free cash flow is defined as net cash from operating activities minus cash payments for capital expenditures minus expenditures for revenue generating assets. Management believes providing free cash flow is useful for investors to understand the Company’s performance and results of cash generation period to period with the exclusion of the item identified above. Management believes the presentation of free cash flow, when combined with the GAAP presentations of cash from operating activities, is beneficial to an investor’s understanding of the Company’s operating performance.

The information contained in this Item 2.02 of this Current Report on Form 8-K is being furnished and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, or incorporated by reference into any filing under the Securities Act of 1933, as amended, of the Exchange Act.

Item 8.01. Other Events.

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, will recognize a $81.2 million reduction to the charge taken in the third quarter of 2024, reflecting 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.

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 Securities and Exchange Commission, 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.
