Operating income of $68 million was a 94-percent year-over-year increase. Average daily shipments rose 3 percent, as did revenue per shipment. The latter increase was due to the impact of higher freight rates, the company said. Smith, in the statement disclosing the results, said the company had a "very successful" peak period. FedEx's acquisition late last year of third-party logistics provider GENCO Distribution System Inc. had an immaterial impact on the quarter's results, the company said. GENCO's results are being included in the FedEx Ground reporting segment, FedEx said. The transaction, terms of which were not disclosed, closed on January 30.
