(the “Partnership”) is filing this Post-Effective Amendment No. 1 (this “Amendment”) to each of the following Registration Statements on Form S-8 (collectively, the “Registration Statements”) to terminate all offerings under such Registration Statements and deregister any and all securities that remain unsold pursuant to the Registration Statements:

On July 10, 2024, among other things, (a) Calumet Merger Sub II LLC merged with and into the Partnership, with the Partnership continuing as the surviving entity and a wholly owned subsidiary of Calumet, Inc. (“New Calumet”), and all of the Common Units were exchanged into the right to receive an equal number of shares of common stock, par value $0.01 per share, of New Calumet (“Common Stock”) and (b) Calumet Merger Sub I LLC merged with and into Calumet GP, LLC (the “General Partner”), with the General Partner continuing as the surviving entity and a wholly owned subsidiary of New Calumet, and all outstanding equity interests of the General Partner were exchanged into the right to receive an aggregate of 5,500,000 shares of Common Stock and 2,000,000 warrants to purchase Common Stock (such transaction, the “Conversion”).

As a result of the completion of the Conversion, this Amendment is being filed by the Partnership to withdraw and remove from registration all of the Plan Units that remain unsold under the Registration Statements. In accordance with an undertaking made by the Partnership in the Registration Statements to remove from registration, by means of a post-effective amendment, any of the Plan Units registered under the Registration Statements that remain unsold at the termination of the offering, the Partnership hereby removes from registration any and all of the Plan Units registered but unsold under the Registration Statements as of the date hereof. The Registration Statements are hereby amended, as appropriate, to reflect the deregistration of such securities.
