This Amendment No. 1 (this “Amendment”) amends and supplements the Schedule 13D filed with the Securities and Exchange Commission (the “SEC”) on February 1, 2021 (the “Schedule 13D”) by the Reporting Persons relating to the shares of common stock, par value $0.01 per share (the “Common Stock”) of NexTier Oilfield Solutions, Inc., a Delaware corporation (the “Issuer”).

Information reported in the Schedule 13D remains in effect except to the extent that it is amended, restated or superseded by information contained in this Amendment. Capitalized terms used but not defined in this Amendment have the respective meanings set forth in the Schedule 13D.

Item 3. Source or Amount of Funds or Other Consideration.

Item 3 of the Schedule 13D is hereby amended to add the following paragraph:

The source of funds for purchases of Common Stock by the Reporting Persons was working capital of THRC Holdings, LP. All such shares of Common Stock, including Common Stock acquired between the date of the Schedule 13D and this Amendment, were acquired by the Reporting Persons through open market transactions.

The information set forth in Item 5 of this Amendment is incorporated herein by reference.

Item 5. Interest in Securities of the Issuer

Item 5 of the Schedule 13D is hereby amended by amending and replacing in their entirety each of Item 5(a), (b) and (c) as follows:

(a)—(b) Each Reporting Person’s beneficial ownership of the Common Stock as of the date of this Amendment is reflected on that Reporting Person’s cover page. The Reporting Persons may be deemed to be the beneficial owners of an aggregate of 16,564,980 shares of Common Stock, representing 7.68% of the 215,750,574 shares of Common Stock outstanding as of August 3, 2021, as reported in the Issuer’s Quarterly Report on Form 10-Q filed with the SEC on August 5, 2021.

Each of the Reporting Persons may be deemed to have shared power to vote or direct the vote and shared power to dispose or to direct the disposition of 16,564,980 shares of Common Stock. THRC Holdings beneficially owns 16,564,980 shares of Common Stock, representing 7.68% of the issued and outstanding shares of Common Stock. THRC Management, as General Partner of THRC Holdings, has exclusive voting and investment power over the shares of Common Stock held by THRC Holdings, and therefore may be deemed to share beneficial ownership of such shares. Dan Wilks, as sole Manager of THRC Management, together with his spouse, Staci Wilks, who share the same household, may be deemed to exercise voting and investment power over the shares of Common Stock directly owned by THRC Holdings and therefore may be deemed to share beneficial ownership of such shares.

The transactions in the shares of Common Stock by the Reporting Persons during the past sixty (60) days are set forth on Schedule I hereto which is incorporated herein by reference.
