Retirement of Rental Equipment

We routinely review our rental fleet for retirement or obsolescence as well as an assessment to determine which units are not of the type, configuration, make or model that our customers are demanding or that are not cost efficient to refurbish, maintain and/or operate. As a result of these reviews, we recorded charges for the retirement of rental equipment of less than $0.1 million, $0.5 million and $0.2 million during the years ended December 31, 2024, 2023 and 2022, respectively.
