Item 2.06

Material Impairments.

On September 18, 2019, Antero Midstream Corporation (the “Company”) commenced a strategic evaluation of its wastewater treatment facility (the “Clearwater Facility”) and related landfill (the “Landfill”). While the Company undertakes this evaluation, the Clearwater Facility and the Landfill will be idled, which is not expected to adversely impact the Company’s operating cash flow. The net book value of the Clearwater Facility and the Landfill were approximately $300 million and $75 million, respectively, as of June 30, 2019. While the Company anticipates it will be required to take an impairment charge relating to these assets, it is unable at this time to estimate the amount of any such impairment charge. The Company expects to provide an update following the completion of its strategic evaluation when it makes a determination of an estimate or range of estimates for any such impairment charge.
