Explanatory Note

This Amendment No. 1 to Schedule 13D (this “Amendment No. 1”) amends and supplements the Schedule 13D filed with the Securities and Exchange Commission on January 11, 2021 (the “Initial Schedule 13D”), relating to the Class A common stock, par value $0.01 per share (the “Common A Shares”), of Liberty Oilfield Services Inc. (the “Issuer”). The Common A Shares and Class B common stock, par value $0.01 per share, of the Issuer (the “Common B Shares” and, together with the Common A Shares, the “Common Shares”) are treated as a single class for purposes of this Schedule 13D because they vote together as a single class. Capitalized terms used herein without definition shall have the meaning set forth in the Initial Schedule 13D.

Item 4.

Purpose of Transaction

Item 4 of the Initial Schedule 13D is hereby amended and supplemented to include the following additional information:

Pursuant to the Amended and Restated Stockholders Agreement dated December 31, 2020 by and among the Issuer, the Schlumberger Parties and the other parties thereto (the “A&R SHA”), the restriction on transfer or disposition of the Common A Shares beneficially owned by the Reporting Persons will expire effective October 1, 2021 (the “Lock-Up Period”). Following expiration of the Lock-Up Period, STC may initiate sales, transfers or other dispositions of a portion of such Common A Shares. Such transactions may be effectuated by means of one or a combination of underwritten offerings, ordinary brokerage transactions, privately negotiated transactions or through any other method permitted by applicable law. The timing and amount of such transactions will depend on market conditions, general economic and industry conditions and other considerations, including applicable securities laws.

Item 5.

Interest in Securities of the Issuer

Item 5 of the Initial Schedule 13D is hereby amended and restated in its entirety as follows:

(a)

As of the date hereof, STC directly holds 66,326,134 Common A Shares, constituting approximately 36.8% of the 180,170,922 outstanding Common Shares. Since SHC controls STC, it is deemed to beneficially own the Common A Shares held directly by STC. Since Schlumberger BV controls SHC, it is deemed to beneficially own the Common A Shares held directly by STC. Since Schlumberger Limited controls Schlumberger BV, it is deemed to beneficially own the Common A Shares held directly by STC. The 180,170,922 outstanding Common Shares are composed of (a) 178,310,595 Common A Shares outstanding as of July 23, 2021, as reported in the Issuer’s Quarterly Report on Form 10-Q filed on July 30, 2021, and (b) 1,860,327 shares of Class B Common Stock outstanding as of July 23, 2021, as reported in the Issuer’s Quarterly Report on Form 10-Q filed on July 30, 2021.

(b)

Schlumberger Limited, Schlumberger BV, SHC and STC have shared voting power and shared dispositive power over the Common A Shares held directly by STC.

(c)

Other than as described herein, the Reporting Persons have not effected any transactions in the Common A Shares.

(d)

The Reporting Persons have the right to receive distributions from, or proceeds from the sale of, the Common A Shares reported herein. Except as set forth in the preceding sentence, no other person is known by the Reporting Persons to have the right to receive or the power to direct the receipt of distributions from, or the proceeds from the sale of, Common A Shares beneficially owned by the Reporting Persons.

(e)

Not applicable.
