Ladies and Gentlemen:

U.S. Well Services Holdings, LLC, a Delaware limited liability company acting in its capacity as successor to U.S. Well Services, Inc. (in such capacity, the “Registrant”), together with the Co-Registrants (collectively, the “Applicants”) hereby file this application for withdrawal of the Registration Statement pursuant to Rule 477 under the Securities Act of 1933, as amended (the “Securities Act”). As provided in that Rule, this request will be deemed granted at the time of filing unless the Commission within 15 calendar days thereafter notifies the Applicants that it will not be granted.

As disclosed in the Current Report on Form 8-K filed by the Registrant on November 7, 2022, on November 1, 2022, the Initial Registrant (i) became an indirect wholly owned subsidiary of ProFrac Holding Corp., a Delaware corporation, by virtue of the merger transaction described therein, and (ii) immediately following the consummation of such transaction, converted from a Delaware corporation into the Delaware limited liability company referred to herein as the Registrant. As members of the corporate family resulting from these transactions, it has now been decided that the Applicants will not engage in the securities offerings contemplated by the Registration Statement.

The Registration Statement has not become effective, and the Applicants hereby confirm that no securities were sold thereunder.

In accordance with Securities Act Rule 457(p), all fees paid in connection with the filing of the Registration Statement will remain available for future use as provided therein.

Should you have any questions regarding the foregoing, please contact James E. Bedar of Brown Rudnick LLP at (617) 856-8167.

Sincerely,

(Brown Rudnick LLP)
