NOTE A – ORGANIZATIO****N AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION

Organization and Description of Business

ArcBest Corporation™ (the “Company”) is a multibillion-dollar integrated logistics company that leverages technology and a full suite of shipping and logistics solutions across multiple modes of transportation to meet customers’ supply chain needs. The Company, which started over a century ago as a local freight hauler, serves as a single end-to-end logistics partner with global reach. The Company’s operations are conducted through itstwo reportable operating segments: Asset‑Based, which consists of ABF Freight System, Inc. and certain other subsidiaries (“ABF Freight”), and Asset-Light, which includes MoLo Solutions, LLC (“MoLo”), Panther Premium Logistics® (“Panther”), and certain other subsidiaries. References to the Company in this Quarterly Report on Form 10-Q are primarily to the Company and its subsidiaries on a consolidated basis.

The Asset-Based segment represented approximately 63% of the Company’s total revenues before other revenues and intercompany eliminations. As of March 2026, approximately 81% of the Asset-Based segment’s employees were covered under the ABF National Master Freight Agreement (the “2023 ABF NMFA”), a collective bargaining agreement with the International Brotherhood of Teamsters (the “IBT”), which will remain in effect through June 30, 2028.

Financial Statement Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) pertaining to interim financial information. Accordingly, these interim financial statements do not include all information or footnote disclosures required by accounting principles generally accepted in the United States for complete financial statements and, therefore, should be read in conjunction with the audited financial statements and accompanying notes included in the Company’s 2025 Annual Report on Form 10-K and other current filings with the SEC. In the opinion of management, all adjustments (which are of a normal and recurring nature) considered necessary for a fair presentation have been included.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual amounts may differ from those estimates.

NOTE B – FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

Financial Instruments

The following table presents the components of cash and cash equivalents and short-term investments:

The Company’s long-term financial instruments are presented in the table of financial assets and liabilities measured at fair value within this Note.

Concentrations of Credit Risk of Financial Instruments

The Company is subject to concentrations of credit risk related to its cash, cash equivalents, and short-term investments. The Company reduces credit risk by maintaining its cash deposits and short-term investments in accounts and certificates of deposit that are primarily FDIC‑insured. However, certain cash deposits and certificates of deposit may exceed federally insured limits. At March 31, 2026 and December 31, 2025, cash deposits and short-term investments totaling $23.4 million and $31.1 million, respectively, were not FDIC‑insured. The Company also holds money market funds, which are invested in U.S. government securities and repurchase agreements collateralized solely by U.S. government securities.

Fair Value Disclosure of Financial Instruments

Fair value disclosures are made in accordance with the following hierarchy of valuation techniques based on whether the inputs of market data and market assumptions used to measure fair value are observable or unobservable:

Fair value and carrying value disclosures of financial instruments are presented in the following table:

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following table presents the assets and liabilities that are measured at fair value on a recurring basis:

NOTE C – GOODWILL AND INTANGIBLE ASSETS

Goodwill represents the excess of cost over the fair value of net identifiable tangible and intangible assets acquired. The goodwill balance of $304.8 million at both March 31, 2026 and December 31, 2025 relates to the Asset-Light segment. The indefinite-lived intangible asset, which is the Panther trade name, totaled $25.7 million at both March 31, 2026 and December 31, 2025.

Finite-lived intangible assets consisted of the following:

NOTE D – INCOME TAXES

The Company’s effective tax benefit rate was 22.3% for the three months ended March 31, 2026, while the effective tax rate for the three months ended March 31, 2025 was 25.0%. The difference between the Company’s effective tax rate and the federal statutory rate resulted from various factors for these periods, including state and foreign income taxes, changes in the cash surrender value of life insurance, and various nondeductible expenses. State tax rates vary among states and average approximately 6.0%, although some state rates are higher, and a small number of states do not impose an income tax.

As of March 31, 2026, the Company’s deferred tax liabilities, which will reverse in future years, exceeded the deferred tax assets. The Company evaluated the total deferred tax assets at March 31, 2026, and concluded that, other than for certain deferred tax assets related to foreign and state tax credit carryforwards and federal and state net operating losses, the assets did not exceed the amount for which realization is more likely than not. In making this determination, the Company considered the future reversal of existing taxable temporary differences, future taxable income, and tax planning strategies.

NOTE E – LEASES

The Company has operating lease arrangements for certain facilities and revenue equipment used in the Asset-Based and Asset-Light segment operations and certain other facilities and office equipment.

The components of operating lease expense were as follows:

The operating cash flows from operating lease activity were as follows:

There were no significant changes to the Company’s operating lease arrangements during the three months ended March 31, 2026. See Note F to the consolidated financial statements in the Company’s 2025 Annual Report on Form 10-K for additional information.

NOTE F – LONG-TERM DEBT AND FINANCING ARRANGEMENTS

Long-Term Debt Obligations

Long-term debt, which consisted of notes payable related to the financing of revenue equipment (tractors and trailers used primarily in Asset-Based segment operations) and certain other equipment, was as follows:

Assets securing notes payable, primarily consisting of revenue equipment, which were included in property, plant and equipment, totaled $386.9 million at March 31, 2026 and $362.5 million at December 31, 2025.

Financing Arrangements

Credit Facility

The Company’s revolving credit facility (the “Credit Facility”) under its Fifth Amended and Restated Credit Agreement (the “Credit Agreement”) has a maturity date of November 25, 2030. The Credit Facility has an initial maximum credit amount of $250.0 million, including a swing line facility in an aggregate amount of up to $40.0 million and a letter of credit sub-facility providing for the issuance of letters of credit up to an aggregate amount of $50.0 million. The Company may request additional revolving commitments or incremental term loans thereunder up to an aggregate amount of up to $125.0 million, subject to the satisfaction of certain additional conditions as provided in the Credit Agreement. During the three months ended March 31, 2026, $26.1 million of letters of credit were issued under our Credit Facility, primarily in support of the Company’s workers’ compensation and third-party casualty claims liabilities in various states in which the Company is self-insured, leaving $223.9 million in available borrowing capacity under the Credit Facility as of March 31, 2026.

Principal payments under the Credit Facility are due upon maturity of the facility; however, borrowings may be repaid at the Company’s discretion, in whole or in part at any time, without penalty, subject to required notice periods and compliance with minimum prepayment amounts. In addition, the Credit Facility requires the Company to pay a fee on unused commitments. The Credit Agreement contains conditions, representations and warranties, events of default, and indemnification provisions that are customary for financings of this type, including, but not limited to, a minimum interest

coverage ratio, a maximum adjusted leverage ratio, and limitations on incurrence of debt, investments, liens on assets, certain sale and leaseback transactions, transactions with affiliates, mergers, consolidations, and sales of assets. The Company was in compliance with the covenants under the Credit Agreement at March 31, 2026.

Accounts Receivable Securitization Program

The Company’s accounts receivable securitization program (“A/R Securitization”) has a maturity date of July 1, 2026. The A/R Securitization provides available cash proceeds of $50.0 million and has an accordion feature allowing the Company to request additional borrowings up to $100.0 million, subject to certain conditions.

Under this program, certain subsidiaries of the Company continuously sell a designated pool of trade accounts receivables to a wholly owned subsidiary which, in turn, may borrow funds on a revolving basis. The A/R Securitization does not qualify for sale treatment. Accordingly, the accounts receivable and related debt obligation remain on the Company’s consolidated balance sheets. This wholly owned consolidated subsidiary is a separate bankruptcy-remote entity, and its assets would be available only to satisfy the claims related to the lenders’ interest in the trade accounts receivable. Borrowings under the A/R Securitization bear interest based upon SOFR, or, to the extent funded by the conduit lender through the issuance of notes, at the commercial paper rate as defined in the agreement, plus a margin in each case, and an annual facility fee. The securitization agreement contains representations and warranties, affirmative and negative covenants, and events of default that are customary for financings of this type, including a maximum adjusted leverage ratio covenant. The Company was in compliance with the covenants under the A/R Securitization at March 31, 2026.

The A/R Securitization includes a provision under which the Company may request, and the program’s letter of credit issuer may issue, standby letters of credit. As of March 31, 2026, $0.3 million in letters of credit were outstanding under the A/R Securitization, leaving $49.7 million in available borrowing capacity under the program.

Notes Payable

The Company financed the purchase of certain revenue equipment through promissory note arrangements totaling $22.1 million during the three months ended March 31, 2026.

On April 24, 2026, the Company announced its Board of Directors declared a dividend of$0.12 per share to stockholders of record as of May 8, 2026.

Treasury Stock

The Company has a program to repurchase its common stock in the open market or in privately negotiated transactions (the “share repurchase program”). The share repurchase program has no expiration date but may be terminated at any time at the Board of Directors’ discretion. Repurchases may be made using the Company’s cash reserves or other available sources.

As of December 31, 2025, the Company had $104.7 million available for repurchases of its common stock under the share repurchase program. During the three months ended March 31, 2026, the Company repurchased 85,011 shares for an

aggregate cost of $7.4 million under the share repurchase program. The Company had $97.3 million remaining under its share repurchase program as of March 31, 2026.

NOTE H – EARNINGS PER SHARE

The following table reflects the computation of basic and diluted earnings per common share:

NOTE I – OPERATING SEGMENT DATA

The Company’s reportable operating segments are as follows:

The Company’s other business activities and operations that are not reportable segments include ArcBest Corporation (the parent holding company) and certain subsidiaries. Certain costs incurred by the parent holding company and the Company’s shared services subsidiary are allocated to the reporting segments. The Company eliminates intercompany transactions in consolidation.

Historically, the second and third calendar quarters of each year usually have the highest tonnage and shipment levels. In contrast, the first quarter generally has the lowest tonnage and shipment levels, although other factors, including the state of the U.S. and global economies; available capacity in the market; yield initiatives; and external events or conditions, such as the modification or implementation of new tariffs or trade policy, may influence quarterly business levels. The Company’s yield initiatives, along with increased technology-driven intelligence and visibility with respect to demand,

have allowed for shipment optimization in non-peak times, reducing the Company’s susceptibility to seasonal fluctuations in recent years.

The Company's President and Chief Executive Officer is the Chief Operating Decision Maker (“CODM”) who makes decisions about resources to be acquired, allocated and utilized in each operating segment. The CODM uses segment revenues, operating expense categories, operating ratios, operating income (loss), and key operating statistics to evaluate performance and allocate resources to the Company’s operations. The Company’stwo reportable segments and the measures used by the CODM to assess performance are consistent with those described in the Company's 2025 Annual Report on 10-K, as are the impacts of seasonal fluctuations on the Company's reportable operating segments.

Further classifications of operations or revenues by geographic location are impracticable and, therefore, are not provided. The Company’s foreign operations are not significant.

The following tables reflect the Company’s reportable operating segment information:

The following table reflects information about revenues from customers and intersegment revenues:

The following table presents operating expenses by category on a consolidated basis:

NOTE J – COMMITMENTS AND CONTINGENCIES

The Company's commitments and contingencies are described in Note N to the consolidated financial statements in the Company's 2025 Annual Report on Form 10-K. The Company continues to be subject to routine legal matters and contractual obligations incurred in the normal course of business and maintains liability insurance against certain risks arising out of the normal course of its business, subject to certain self-insurance retention limits. Management does not believe that these matters will have a material adverse effect on the Company's financial condition, results of operations, or cash flows.

The Company has purchase obligations, consisting of authorizations to purchase and binding agreements with vendors, relating to revenue equipment used in our Asset-Based operations, other equipment, facility improvements, software, service contracts, and other items for which amounts were not accrued in the consolidated balance sheet as of March 31, 2026. These purchase obligations totaled $120.0 million as of March 31, 2026, with $102.6 million expected to be paid within the next year, provided that vendors complete their commitments to the Company. As of March 31, 2026, the amount of our purchase obligations increased $14.2 million from December 31, 2025, primarily related to ABF Freight revenue equipment.

There have been no other significant changes to the Company's commitments and contingencies as reported in the Company's 2025 Annual Report on Form 10-K since December 31, 2025.
