DEREGISTRATION OF SECURITIES

These Post-Effective Amendments (these “Post-Effective Amendments”) relate to the following Registration Statements on Form S-8 (collectively, the “Registration Statements”), originally filed by Hi-Crush Partners LP, a Delaware limited partnership (the “Registrant”), with the Securities and Exchange Commission:

On May 22, 2019, the common unitholders of the Registrant approved the Plan of Conversion (the “Plan of Conversion”), pursuant to which the Registrant would be converted from a Delaware limited partnership to a Delaware corporation named “Hi-Crush Inc.” (the “Company”) through a series of transactions (the “Conversion”). On May 31, 2019, the Registrant filed a Certificate of Conversion and a Certificate of Incorporation with the Secretary of State of the State of Delaware to effect the Conversion and change the Registrant’s name to “Hi-Crush Inc.” In connection with the Conversion, each outstanding Common Unit was converted into the right to receive one share of the Company’s common stock, par value $0.01 per share.

In connection with the Conversion, the Registrant has terminated any and all offerings of the Registrant’s securities pursuant to the Registration Statements. Accordingly, the Registrant hereby terminates the effectiveness of the Registration Statements and, in accordance with an undertaking made by the Registrant in Part II of the Registration Statements to remove from registration, by means of a post-effective amendment, any securities that had been registered for issuance but remain unsold at the termination of the offering, the Registrant hereby removes from registration any and all securities registered but which remain unsold under the Registration Statements as of the date hereof.
