Section 1 - Conflict Minerals Disclosure

NexTier Oilfield Solutions Inc. (including its subsidiaries, the “Company”), a Delaware corporation, files this Specialized Disclosure Form (Form SD) to comply with Rule 13p-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) for the calendar year ended on December 31, 2021.

Item 1.01 Conflict Minerals Disclosure and Report

Conflict Minerals Disclosure

The Company has evaluated its current product lines and determined that, during the 2021 calendar year, certain products that the Company manufactured for sale to third parties contained “conflict minerals” (as defined in Section 1502(e)(4) of the Dodd-Frank Wall Street Reform and Consumer Protection Act), and that such conflict minerals were necessary to the functionality or production of those manufactured products. Therefore, the Company conducted the reasonable country of origin inquiry required by Rule 13p-1, which was reasonably designed to determine whether any of the necessary conflict minerals in our products originated in a Covered Country or came from recycled or scrap sources. Our reasonable country of origin inquiry included reaching out to the Company’s suppliers to request information on the origin of any conflict minerals contained in the materials supplied to the Company, including the sources of conflict minerals that are supplied to them from sub-tier suppliers. Based on the results of the inquiry, the Company has determined that some of the conflict minerals contained in its products did not originate in the DRC or an adjoining country. Nevertheless, the Company was unable to determine with any reasonable certainty the source and chain of custody of all of the conflict minerals used in its products during 2021.

A copy of the Conflict Minerals Report is also publicly available through the Company’s website at www.nextierofs.com. Information contained on or available through the Company’s website is not a part of or incorporated into this Form SD or any other report that the Company may file with or furnish to the U.S. Securities and Exchange Commission.
