The Company, which started over a century ago as a local freight hauler, is now a logistics powerhouse with global reach. The Company’s operations are conducted through its two 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 66% of the Company’s total revenues before other revenues and intercompany eliminations for the six months ended June 30, 2025. As of June 2025, approximately 81% of the Asset-Based segment’s employees were covered under a collective bargaining agreement, the ABF National Master Freight Agreement (the “2023 ABF NMFA”), with the International Brotherhood of Teamsters (the “IBT”), which will remain in effect through June 30, 2028.
