Calumet has also described the use of non-GAAP financial measures such as EBITDA, Adjusted EBITDA and Adjusted EBITDA with Tax Attributes. The company defines these measures in detail and explains that they are used by management and external stakeholders to assess operating performance, evaluate the ability of assets to generate cash sufficient to support indebtedness, and analyze returns on capital.

In addition, Calumet has disclosed certain internal control and reporting matters. In a Form 8-K, the company reported that its Audit Committee concluded that unaudited interim consolidated financial statements for periods ended March 31, 2025 and June 30, 2025 required restatement due to an error in the unaudited condensed consolidated statements of cash flows. The company stated that the error related to misclassification of certain amounts between cash flows from operating activities and cash flows from financing activities, and that it had no impact on revenue, net income (loss) or cash and cash equivalents. Calumet identified a material weakness related to the preparation and review of the unaudited condensed consolidated statements of cash flows and indicated that it intended to restate the affected financial statements and file amended Quarterly Reports on Form 10-Q.
Calumet’s SEC filings also reference transactions involving its Shreveport refinery assets. In a Form 8-K, the company reported that its subsidiary Calumet Shreveport Refining, LLC entered into a sale and leaseback transaction for certain property comprising the Shreveport refinery fuels terminal, truck rack and related piping and equipment. The transaction was documented under a Master Lease Agreement and a property schedule with Stonebriar Commercial Finance LLC. The company described the lease term, rental payments, and an option to repurchase the leased assets after a specified period, as well as the use of a portion of the proceeds to pay obligations under a prior property schedule. Related amendments to the company’s credit agreement and a monetization master agreement were also disclosed.
