Fourth quarter operating results increased primarily due to volume growth and disciplined revenue and portfolio management. These factors were partially offset by costs to support strong demand, increased variable compensation expense, and higher labor rates.
Net results include a loss on debt extinguishment of $393 million ($297 million net of tax).
FedEx Express fourth quarter operating income more than doubled year over year, driven by exceptional growth in international export and U.S. domestic package services. Operating margin increased 260 basis points (an adjusted 340 basis points; adjusted measures exclude the items listed below for the applicable fiscal year), as improved network optimization and asset utilization enabled profit growth from record fourth quarter volume.
FedEx Ground reported record earnings for the quarter and revenue growth of 27%. The revenue increase was primarily driven by strong growth in business-to-business shipments and a 14% rise in revenue per package. Operating margin improved 310 basis points to 13.6% due to strong revenue growth and slower growth in purchased transportation expenses, aided by a higher mix of business-to-business shipments and benefits from dynamic route optimization technology. This improvement was partially offset by higher expenses driven by constrained labor availability.
FedEx Freight reported record earnings and operating margin of 16.1% for the quarter, as average daily shipments grew 30% and revenue per shipment increased 6%. Operating results improved primarily due to the continued focus on revenue quality and profitable growth.
