NOTICE OF 2025 ANNUAL MEETING AND PROXY STATEMENT

To Our Stockholders:

You are cordially invited to attend the 2025 Annual Meeting of Stockholders (the “Annual Meeting”) of Calumet, Inc. (“we,” “our,” “us,” or the “Company”) to be held virtually at www.virtualshareholdermeeting.com/CLMT2025 on June 10, 2025, at 9:00 a.m. ET. This will be our inaugural Annual Meeting of Stockholders following our conversion from a Master Limited Partnership to a C-Corporation completed on July 10, 2024.

The matters expected to be acted upon at the Annual Meeting are described in detail on the following pages.

We are using a U.S. Securities and Exchange Commission rule that allows us to furnish our proxy materials over the internet. As a result, we are mailing to our stockholders a Notice Regarding the Availability of Proxy Materials instead of a paper copy of the following Proxy Statement, together with our 2024 Annual Report. The Notice Regarding the Availability of Proxy Materials contains instructions on how to access those documents over the internet or receive a paper copy of those documents. We believe that this process will conserve natural resources and reduce the costs of printing and distributing our proxy materials.

It is important that you use this opportunity to take part in the affairs of the Company by voting on the business to come before the Annual Meeting. Whether or not you plan to attend the Annual Meeting, please vote electronically via the internet or by telephone as described in the Notice Regarding the Availability of Proxy Materials and under “Information About the Meeting-Internet and Telephone Voting” within the following Proxy Statement, or alternatively, if you have received paper copies of our proxy materials, please complete, date, sign, and promptly return the accompanying proxy card or voting instruction form by mail using the enclosed envelope so that your shares may be represented at the Annual Meeting. Returning or completing the proxy card does not deprive you of your right to attend the Annual Meeting and vote your shares.

Thank you for your continued support of the Company.

Sincerely,

/s/ Todd Borgmann

Todd Borgmann

President & Chief Executive Officer
