Depreciation and amortization expense for property, plant and equipment during the first quarters of 2026 and 2025 was $791 and $743 million, respectively. As of March 31, 2026, we determined that $50 million of assets within our U.S. Domestic Package segment met the criteria to be classified as held for sale and are presented within Other current assets in our consolidated balance sheet.

In the first quarter of 2026, as part of our Network Reconfiguration and Efficiency Reimagined initiatives, we closed 23 leased and owned buildings, 22 of which have been permanently closed. We have identified 27 additional buildings for closure in 2026. We will continue to review expected changes in volume in our integrated air and ground network and may identify additional buildings for closure. It is reasonably possible that our plans will also result in further revisions to our estimates of the useful lives and salvage values of certain of our long-lived assets. Any further revisions to these plans could further accelerate depreciation expense and lead to the recognition of additional charges related to early retirements in future periods. For additional information, see note 16 to the unaudited, consolidated financial statements.

We recorded $47 million in gains on sales of properties during the three months ended March 31, 2026. These gains were primarily within our U.S. Domestic Package segment and are included within Other expenses in our unaudited statement of consolidated income. For additional information, see note 16 to the unaudited, consolidated financial statements.

There were no material impairment charges to property, plant and equipment during the three months ended March 31, 2026 or 2025. We will continue to monitor our long-lived asset groups for impairment.
