FedEx Corporation announced plans to lay off more than 480 employees and close two facilities by this fall as part of a broader network integration strategy. The logistics provider disclosed the restructuring in an official statement.

The company stated it will shut down parcel distribution centers in Greensboro, North Carolina and Omaha, Nebraska, resulting in 164 and 102 job reductions respectively. In a letter to the Nebraska Department of Labor, FedEx noted that operations from the Omaha facility will be shifted to another site located within a 50-mile radius.

In addition, 84 jobs will be cut at a facility in Des Moines, Iowa, and the company also plans to reduce 131 positions at sites in Garland and Plano, Texas during the summer. The layoffs and closures are scheduled to take effect on September 1.

FedEx attributed these changes to its “Network 2.0” initiative—a multi-year effort to consolidate its separate FedEx Express and FedEx Ground networks in order to improve delivery efficiency and reduce transportation costs.

The news was first reported by the Commercial Appeal in Memphis, Tennessee, where FedEx is headquartered. The company added that many affected employees may be offered other roles within FedEx, though some may need to commute longer distances or relocate.

FedEx executives noted in a recent earnings call that the company aims to shut down 30% of its package terminals within the next two years. In June, FedEx merged 63 stations across 20 local markets, and to date, it has optimized operations at 100 U.S. facilities.
