DEREGISTRATION OF UNSOLD SECURITIES

This Post-Effective Amendment No. 1 is being filed to deregister all shares of Class A common stock, $0.01 par value per share (the “Common Stock”), of Select Interior Concepts, Inc. (the “Company”) that had been registered and remain unsold under the Registration Statement on Form S-1 (No. 333-226101), pertaining to the registration of 25,614,626 shares of Common Stock by the selling stockholders named therein (the “Registration Statement”), filed with the U.S. Securities and Exchange Commission (the “SEC”) on July 9, 2018.

On August 8, 2021, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among the Company, Astro Stone Intermediate Holding, LLC (“Parent”), a Delaware limited liability company and affiliate of Sun Capital Partners Group VII, LLC (“Sun”), and Astro Stone Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Subsidiary”).  Upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Subsidiary will be merged with and into the Company (the “Merger”) with the Company surviving the Merger as a wholly-owned subsidiary of Parent.

As a result of the Merger, the Company has terminated all offerings of its securities pursuant to the Registration Statement. In accordance with an undertaking made by the Company in the Registration Statement to remove from registration, by means of a post-effective amendment, any securities registered under the Registration Statement that remain unsold at the termination of the offering, the Company hereby removes from registration all shares of Common Stock of the Company registered under the Registration Statement as of the date of this Post-Effective Amendment. In that regard, and for the avoidance of doubt, any selling stockholders of the Company under the Registration Statement no longer own any shares of Common Stock as a result of the Merger.
