Heartland Express is a truckload carrier operating through subsidiaries under the Heartland Express, Millis Transfer, Smith Transport, and CFI brands, providing short, medium, and long-haul dry van and temperature-controlled transportation services to major shippers across the United States and cross-border freight services to Mexico. The company operates approximately 27 strategically positioned terminal facilities near major metropolitan areas, shipping corridors, and distribution centers, with roughly 98% of its miles generated by company drivers operating company-owned equipment. Revenue is earned primarily on a per-loaded-mile or per-load basis with customers on predominantly net-30 payment terms, supplemented by fuel surcharges to offset long-term fuel price increases, and the company maintains a relatively young fleet to minimize operating costs and enhance service quality.
