Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC.

Management’s Annual Report on Internal Control Over Financial Reporting

The management of Calumet, Inc. (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of the financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and the board of directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025, based on criteria for effective internal control over financial reporting described in “Internal Control - Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (“COSO”), and has concluded that we maintained effective internal control over financial reporting as of December 31, 2025.

Grant Thornton LLP, an independent registered public accounting firm, has audited the effectiveness of our internal controls over financial reporting as of December 31, 2025, as stated in their report, which is included herein.

Remediation of Previously Reported Material Weakness

As of December 31, 2025, we have remediated the previously disclosed material weakness related to the presentation and classification of information on the statement of cash flows for the periods ended March 31, 2025 and June 30, 2025 that caused the misclassification of certain amounts between cash flows from operating activities and cash flows from financing activities.

With oversight from senior management, as well as oversight by the audit committee of the board of directors, we implemented changes to our internal control over financial reporting, which contributed to the remediation of the material weakness described above. Remediation activities included the following:

These remediation actions have been in operation for a sufficient period of time and management has performed adequate testing to conclude that the controls are operating effectively and the material weakness has been remediated as of December 31, 2025.

Changes in Internal Control over Financial Reporting

Other than the actions to remediate the material weakness in our internal control over financial reporting as described above, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the period ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
