 Depreciation expense was $35.0 million, $38.5 million, and $40.9 million in 2022, 2021 and 2020, respectively. The decrease in property, plant and equipment in 2022 primarily reflects a $69.8 million reduction related to our divestitures and associated impairments described in Note 2, partially offset by investments to expand our mat rental fleet.
