UNITED PARCEL SERVICE INC

Building and maintaining long-term customer relationships through superior service is a competitive strength of UPS. In 2024, we served 1.6 million shipping customers and more than 10.1 million delivery recipients daily. For the year ended December 31, 2024, one customer, Amazon.com, Inc. and its affiliates, represented approximately 11.8% of our consolidated revenues, substantially all of which was within our U.S. Domestic Package segment. In the first quarter of 2025, we entered into an agreement in principle with this customer that will provide for a reduction in their volume by more than 50% by June 2026. For additional information on the expected operational and financial impacts arising from this agreement, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations”.
