W e caution that these statements, including prospects for MRL, our ability to execute on strategies and realize expected benefits therefrom, future actions, deleveraging and estimated mid-cycle Adjusted EBITDA are not guarantees of future performance or an indicator of future results, actual market value or future expected returns and you should not rely unduly on them, as they involve risks, uncertainties, and assumptions that we cannot predict. In addition, we have based many of these forward-looking statements on assumptions about future events that may prove to be inaccurate. W hile our management considers these assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predi ct and many of which are beyond our control, including risks related to available capital, actions by third parties (including customers, regulators and financing sources), construction, transportation and feedstock costs, and commodity prices.

RINs Legal Summary CALUMET SPECIALTY PRODUCTS PARTNERS, L.P. Congress included a small refinery exemption (SRE) in the Clean Air Act to address the disproportionate economic hardship of the Renewable Fuels Standard on small refiners like Calumet Calumet’s two small refineries consistently received SREs before 2019, and had submitted SRE petitions for 2019-2022 EPA in 2022 issued a blanket denial of all industry Small Refinery Exemptions, which the Federal 5th Circuit Court has now overturned The 5th Circuit vacated EPA’s Shreveport denial as “impermissibly retroactive; contrary to law; and counter to the record evidence” The D.C. Circuit has granted Great Falls’ motion for a stay while that case remains pending Based on current information, we believe the most likely outcome is either obtaining our SREs or reaching an alternative resolution If an SRE is received, the value of the balance sheet liability is zero for the compliance years the SRE is granted If we are ultimately unsuccessful in obtaining our SREs, the timing, amount and form of our actual liability may depend upon the resolution obtained, potentially as part of subsequent litigation. For example, if resolution for 2019 and 2020 uses the market price of RINs on the day the EPA was obligated to rule on our 2019 SRE petition, the value of the liability would be $50.7 million © 2023 Calumet Specialty Products Partners, L.P.
