Terms such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “forecast,” “foresee,” “intend,” “may,” “plan,” “predict,” “project,” “scheduled,” “should,” “would,” and similar expressions and the negatives of such terms are intended to identify forward-looking statements. These statements are based on management’s beliefs, assumptions, and expectations based on currently available information, are not guarantees of future performance, and involve certain risks and uncertainties (some of which are beyond our control). Although we believe that the expectations reflected in these forward-looking statements are reasonable as and when made, we cannot provide assurance that our expectations will prove to be correct. Actual outcomes and results could materially differ from what is expressed, implied, or forecasted in these statements due to a number of factors, including, but not limited to: the effects of a widespread outbreak of an illness or disease or any other public health crisis, as well as regulatory measures implemented in response to such events; external events which may adversely affect us or the third parties who provide services for us, for which our business continuity plans may not adequately prepare us, including, but not limited to, acts of war or terrorism, or military conflicts; data privacy breaches, cybersecurity incidents, and/or failures of our information systems, including disruptions or failures of services essential to our operations or upon which our information technology platforms rely; interruption or failure of third-party software or information technology systems or licenses; untimely or ineffective development and implementation of, or failure to realize the potential benefits associated with, new or enhanced technology or processes, including our customer pilot offering of Vaux; the loss or reduction of business from large customers or an overall reduction in our customer base; the timing and performance of growth initiatives and the ability to manage our cost structure; the cost, integration, and performance of any recent or future acquisitions and the inability to realize the anticipated benefits of the acquisition within the expected time period or at all; unsolicited takeover proposals, proxy contests, and other proposals/actions by activist investors; maintaining our corporate reputation and intellectual property rights; nationwide or global disruption in the supply chain resulting in increased volatility in freight volumes; competitive initiatives and pricing pressures; increased prices for and decreased availability of equipment, including new revenue equipment, decreases in value of used revenue equipment, and higher costs of equipment-related operating expenses such as maintenance, fuel, and related taxes; availability of fuel, the effect of volatility in fuel prices and the associated changes in fuel surcharges on securing increases in base freight rates, and the inability to collect fuel surcharges; relationships with employees, including unions, and our ability to attract, retain, and upskill employees; unfavorable terms of, or the inability to reach agreement on, future collective bargaining agreements or a workforce stoppage by our employees covered under ABF Freight’s collective bargaining agreement; union employee wages and benefits, including changes in required contributions to multiemployer plans; availability and cost of reliable third-party services; our ability to secure independent owner-operators and/or operational or regulatory issues related to our use of their services; litigation or claims asserted against us; governmental regulations; environmental laws and regulations, including emissions-control regulations; default on covenants of financing arrangements and the availability and terms of future financing arrangements; our ability to generate sufficient cash from operations to support significant ongoing capital expenditure requirements and other business initiatives; self-insurance claims, insurance premium costs, and loss of our ability to self-insure; potential impairment of long-lived assets and goodwill and intangible assets; general economic conditions and related shifts in market demand that impact the performance and needs of industries we serve and/or limit our customers’ access to adequate financial resources; increasing costs due to inflation and higher interest rates; seasonal fluctuations, adverse weather conditions, natural disasters, and climate change; and other financial, operational, and legal risks and uncertainties detailed from time to time in ArcBest Corporation’s public filings with the Securities and Exchange Commission (“SEC”).

ADDITIONAL INFORMATION Note: ArcBest Corporation reports its financial results in accordance with generally accepted accounting principles (“GAAP”). However, management believes that certain non-GAAP performance measures utilized for internal analysis provides analysts, investors, and others the same information that we use internally for purposes of assessing our core operating performance and provides meaningful comparisons between current and prior period results, as well as important information regarding performance trends. Accordingly, using these measures improves comparability in analyzing our performance because it removes the impact of items from operating results that, in management's opinion, do not reflect our core operating performance. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, our reported results. These financial measures should not be construed as better measurements than operating income, operating cash flow, net income or earnings per share, as determined under GAAP. Reconciliations of GAAP to Non-GAAP Financial Measures (Unaudited) 39

Forward-Looking Non-GAAP Financial Measures 40 All forward-looking financial targets in this presentation assume a consolidated tax rate of 25%. Consolidated non-GAAP earnings per share and non-GAAP return on capital employed are non-GAAP financial measures that most closely correlate with consolidated earnings per share and return on capital employed. These non-GAAP measures exclude purchase accounting amortization, which is expected to total $7M pre-tax in 2028. These non-GAAP measures also exclude innovative technology costs, life insurance proceeds, changes in cash surrender value of life insurance policies and income taxes related to the annual vesting of restricted stock units, each of which cannot be estimated for 2028 and could be material. As a result, we are unable to provide quantitative reconciliations to the most closely correlated GAAP measure. Non-GAAP Asset-Based Operating Ratio is a non-GAAP financial measure that most closely correlates with Asset-Based Operating Ratio. Non-GAAP Asset-Based OR could be adjusted for non-recurring infrequent or unusual items. Because the timing, amount and nature of any adjustments are unknown, and any adjustments could be material in future periods, we are unable to provide quantitative reconciliations to the most closely correlated GAAP measure. Asset-Light non-GAAP operating income range of $40M to $70M excludes GAAP impacts from purchase accounting amortization, which are expected to total $7M in 2028. Including these impacts, the Asset-Light GAAP operating income would range from $33M to $63M in 2028. See reconciliation table to the right.
