Item 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

The International Brotherhood of Teamsters (the “IBT”), and certain local unions affiliated with the IBT (the “Unions”), ratified the supplemental agreements for 2018-2023 previously disclosed in the Report on Form8-K filed July11, 2018 by ArcBest Corporation (the “Company”). As a result, ABF Freight System,Inc. (“ABF Freight”), the largest subsidiary of the Company, New England Teamsters and Trucking Industry Pension Fund (the “Fund”), and the Unions have entered into a Withdrawal Agreement and a Reentry Agreement (collectively, the “Agreements”).

to the terms of the Agreements, ABF Freight has retroactively withdrawn as a participating employer in the Fund and reached a settlement of withdrawal liability with the Fund. ABF Freight simultaneously re-entered the Fund as a new participating employer free from any pre-existing withdrawal liability.

to the Withdrawal Agreement, the withdrawal liability was settled through an initial lump sum cash payment of $15 million which was paid August31, 2018, plus monthly payments to the Fund over a period of 23 years. In accordance with current tax law, these payments will be deductible when paid, reducing, to the extent deductible, the actual after tax cost to ABF Freight of the settlement. The Agreements (1)reduce the total withdrawal liability of ABF Freight, (2)strengthen the Fund’s financial position, (3)provide additional security to the ABF Freight employees who rely on the Fund for retirement benefits, and (4)reduce the future contributions required by ABF Freight to the Fund without a corresponding decrease in benefits payable to participating ABF Freight employees. These Agreements have no impact or bearing on any of the other multiemployer pension plans to which ABF Freight contributes.
