EXPLANATORY NOTE

This Amendment No. 1 (this “Amendment”) to Form 8-A (the “Registration Statement”) is being filed pursuant to Section 12(b) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), by Hi-Crush Inc., a Delaware corporation (“Hi-Crush”), as the successor registrant to Hi-Crush Partners LP, a Delaware limited partnership (“HCLP”). Effective May 31, 2019, HCLP converted from a Delaware limited partnership to a Delaware corporation (the “Conversion”). In accordance with Rule 12g-3 under the Exchange Act, upon the effective time of the Conversion, the common stock of Hi-Crush, par value $0.01 per share (the “Common Stock”), was deemed to be registered under Section 12(b) of the Exchange Act as Hi-Crush is deemed to be the successor registrant to HCLP. Hi-Crush expressly adopts the Registration Statement, as modified by this Amendment, as its own registration statement for all purposes of the Exchange Act. The Common Stock will trade on the New York Stock Exchange under the ticker symbol “HCR.”

This Amendment amends the Registration Statement as follows:

A description of the Common Stock is contained in “Description of Hi-Crush Inc.’s Capital Stock” set forth in Hi-Crush’s Proxy Statement filed on February 20, 2019, which is incorporated herein by reference.
