ArcBest Announces First Quarter 2026 Results

Delivered growth in Asset-Based shipments and tonnage and improved Asset-Light profitability Returned more than $10 million to shareholders through a balanced capital allocation approach ArcBest® (Nasdaq: ARCB), a leader in supply chain logistics, announced financial results for the first quarter ended March 31, 2026. First quarter 2026 revenue totaled $998.8 million, compared to $967.1 million in the prior-year period. Net loss was $1.0 million, or a loss of $0.05 per diluted share, versus net income of $3.1 million, or $0.13 per diluted share, in the first quarter of 2025. On a non-GAAP basis, net income was $7.2 million, or $0.32 per diluted share, compared to $11.9 million, or $0.51 per diluted share, in the prior year. “We began 2026 with growth in Asset-Based shipments and tonnage and continued improvement in Asset-Light profitability,” said Seth Runser, ArcBest President and CEO. “Our teams continue to deliver a premium experience for our customers despite a dynamic and uncertain environment, and their alignment around our strategy and priorities gives us confidence in our ability to execute and deliver on our long-term targets.” Results of Operations Comparisons Asset-Based First Quarter 2026 Versus First Quarter 2025 Revenue of $655.0 million compared to $646.3 million, a per-day increase of 2.2 percentTonnage per day increase of 6.5 percentShipments per day increase of 1.8 percentBilled revenue per shipment increase of 0.6 percentBilled revenue per hundredweight decrease of 3.9 percentWeight per shipment increase of 4.6 percentOperating income of $17.5 million and an operating ratio of 97.3 percent, compared to $26.4 million and 95.9 percent Tonnage growth was driven by higher shipment volumes and an increase in weight per shipment, reflecting changes in freight profile. Revenue per shipment benefited from the higher weight per shipment, partially offset by lower revenue per hundredweight as the freight profile shifted toward heavier shipments. Customer contract renewals and deferred pricing agreements averaged a 6.3 percent increase during the first quarter, and LTL industry pricing remains rational. Operating expenses increased due to additional labor supporting shipment growth, annual union wage adjustments, increased fuel prices, and higher equipment depreciation. On a sequential basis, first quarter daily revenue was down 1.5 percent compared to the fourth quarter of 2025. Tonnage per day increased 1.0 percent, driven by a 2.6 percent increase in weight per shipment, partially offset by a 1.6 percent decline in daily shipments. Billed revenue per shipment increased 1.7 percent due to the heavier freight profile and increased fuel surcharge revenue, offset in part by a modest decline in revenue per hundredweight reflecting the changes in freight profile. The operating ratio increased by 110 basis points, an improvement relative to typical seasonality due in part to a softer-than-normal fourth quarter. Asset-Light First Quarter 2026 Versus First Quarter 2025 Revenue of $377.7 million compared to $356.0 million, a per-day increase of 7.0 percentShipments per day increase of 9.8 percentRevenue per shipment decrease of 2.6 percentPurchased transportation expense was 86.2 percent of revenue compared to 85.6 percentOperating income of $0.2 million compared to operating loss of $4.4 millionOn a non-GAAP basis, operating income of $2.8 million compared to operating loss of $1.2 millionAdjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”), as defined in the attached non-GAAP reconciliation tables, of $4.2 million compared to $0.2 million Revenue increased primarily due to shipment growth led by Managed, which more than offset a strategic reduction in less profitable truckload volumes. Revenue per shipment decreased, as higher rates related to tightening capacity and increased fuel costs were more than offset by the higher mix of Managed business, which typically carries smaller shipment sizes and lower revenue per shipment. Revenue growth combined with productivity improvements drove the operating income in the quarter, compared to a loss in the prior year. Compared sequentially to the fourth quarter of 2025, first quarter daily revenue increased 4.3 percent reflecting a 7.4 percent increase in shipments per day, partially offset by a 2.9 percent decline in revenue per shipment. Revenue growth and productivity improvements resulted in non-GAAP operating income, compared to break even in the previous quarter.

ARCBEST CORPORATION RECONCILIATIONS OF GAAP TO NON-GAAP FINANCIAL MEASURES Non-GAAP Financial Measures We report our financial results in accordance with U.S. generally accepted accounting principles (“GAAP”). However, management believes that certain non-GAAP financial measures and ratios utilized internally to assess core performance offer analysts, investors, and others insights into performance trends by excluding items from operating results that management believes do not reflect our core operating performance. Our calculations may not be comparable to similarly titled measures of other companies as other companies may calculate non-GAAP measures differently. Certain information discussed in the scheduled conference call could be considered non-GAAP measures. Non-GAAP financial measures should be viewed in addition to, and not as an alternative or a better measurement than operating income, net income (loss) or earnings per share, as determined under GAAP, which are the most directly comparable measures for the periods presented.

ARCBEST CORPORATION RECONCILIATIONS OF GAAP TO NON-GAAP FINANCIAL MEASURES – Continued Adjusted Earnings Before Interest, Taxes, Depreciation, and Amortization (Adjusted EBITDA) Adjusted EBITDA is used for business planning and as a key performance measure, particularly because it excludes certain significant expenses resulting from strategic decisions or other factors rather than core daily operations, such as amortization of acquired intangibles and software of the Asset-Light segment. The calculation of Consolidated Adjusted EBITDA as presented below begins with net income (loss), which is the most directly comparable GAAP measure. The calculation of Asset-Light Adjusted EBITDA as presented below begins with operating income (loss), as other income (costs), income tax provision (benefit), and net income (loss) are reported at the consolidated level and not included in the operating segment financial information evaluated by management to make operating decisions.

ARCBEST CORPORATION RECONCILIATIONS OF GAAP TO NON-GAAP FINANCIAL MEASURES – Continued Notes to Non-GAAP Financial Tables The following footnotes apply to the non-GAAP financial tables presented in this press release. 1) Represents costs related to our customer pilot offering of Vaux and initiatives to optimize our performance through technological innovation. 2) Represents the amortization of acquired intangible assets in the Asset-Light segment. 3) For first quarter 2026, ArcBest reported a net loss on a GAAP basis and reported net income on a non-GAAP basis. The average common shares outstanding used to calculate non-GAAP diluted earnings per share for first quarter 2026 were adjusted to include unvested restricted stock awards, which were excluded from the calculation of GAAP diluted earnings per share due to the net loss.

The tax effects of non-GAAP adjustments are calculated based on the statutory rate applicable to each item based on tax jurisdiction unless the nature of the item requires the tax effect to be estimated by applying a specific tax treatment. 6) Includes amortization of intangibles associated with acquired businesses.
