As of March 29, 2025, the Company included approximately $20 million of certain property, plant and equipment primarily related to corporate assets as held for sale within other assets on the unaudited condensed consolidated balance sheets. Depreciation expense in the three months ended March 29, 2025 and March 30, 2024 was $43.4 million and $45.7 million, respectively. Change in estimated useful lives In accordance with its policy, the Company reviews the estimated useful lives of its property, plant and equipment on an ongoing basis. This review indicated that the actual lives of certain assets were longer than the estimated useful lives used for depreciation purposes in the Company’s financial reporting. As a result, effective December 29, 2024, the first day of fiscal 2025, the Company changed certain estimates of the useful lives to better reflect the estimated periods during which these assets will remain in service. The estimated useful lives of machinery and equipment, which was previously 5 years increased to 7 years, and building improvements that was previously 10 years increased to 15 years. The effect of this change in estimate reduced depreciation expense by $4.5 million during the three months ended March 29, 2025, increasing net income available to Charles River Laboratories International, Inc. common shareholders by $3.4 million and basic and diluted earnings per share by approximately $0.07.
