**Section 1 – Conflict Minerals Disclosure**

**Item 1.01 Conflict Minerals Disclosure and Report**

Section 13(p) of the Securities Exchange Act of 1934 and Rule 13p-1 thereunder (collectively, the "conflict mineral rules") require certain disclosures concerning supply sources for conflict minerals –consisting of gold, tin, tungsten, or tantalum – that may be necessary to the manufacture or functionality of a company's products. Terms and phrases used but not defined in this disclosure have the meanings given under the conflict mineral rules.

No conflict mineral is intentionally added to, or serves as a functional component of, products sold by Imperial. However, the manufacturing process for certain of Imperial's refined petroleum and petrochemical products utilizes catalysts which include tin, tungsten, or gold compounds as active ingredients. Depending on the type of catalysis process used, trace amounts of such minerals may exist in some of our finished products.

We understand the staff of the U.S. Securities and Exchange Commission ("SEC") has previously issued oral guidance that conflict mineral compounds are not subject to reporting under the conflict mineral rules. However, in the absence of affirmative written SEC guidance on this point Imperial has conducted in good faith a reasonable country of origin inquiry regarding the conflict minerals described above for 2025. Such inquiry is reasonably designed to determine whether any of these minerals originated in the Democratic Republic of the Congo or an adjoining country (the "covered countries"), or are from recycled or scrap sources.

The tin, tungsten, or gold catalysts used by Imperial in 2025 were purchased from third party suppliers. Imperial's country of origin inquiry includes obtaining from each of these suppliers for catalysts containing tin, tungsten, or gold compounds an annual written declaration in the form of the Conflict Minerals Reporting Template promulgated by the Responsible Minerals Initiative ("RMI") or similar conflict mineral statement. Our contracts with each of these catalyst suppliers also require the suppliers to have and maintain procedures reasonably designed to ensure that all conflict minerals necessary to the functionality of products manufactured by the supplier or contracted by the supplier to be manufactured that are sold to Imperial will be conflict free.

With respect to products we manufactured or contracted to manufacture in 2025, we have obtained completed declarations from each of our two third-party suppliers of catalysts containing tin, tungsten, or gold compounds.

One out of two suppliers certified that the tin, tungsten, or gold used in their catalysts did not originate in the covered countries. Based on this inquiry, we conclude that, with respect to catalysts containing tin, tungsten, or gold compounds from this supplier which were used in the manufacture of products by Imperial in 2025, such minerals did not originate in the covered countries.

The one remaining supplier indicated in its declaration that some of the smelters in their respective supply chains source tin, tungsten and/or gold from the covered countries (the "covered country declarations"). This supplier's covered country declarations were provided on a company basis rather than a product basis so it is not known with certainty that minerals from the covered countries were actually used to produce catalysts sold to Imperial. Covered country declarations represented that any covered country smelters or refiners used in the supplier's supply chain in 2025 were "conformant" within the meaning of the RMI standards. Under RMI definitions, "conformant" means smelters and refiners that have successfully completed an assessment against the applicable Responsible Minerals Assurance Process ("RMAP") or an equivalent cross-recognized assessment. RMAP includes Supply Chain Transparency Audit Protocols for tin, tungsten, or gold, as applicable, under which a "conformant" smelter must have completed a RMAP conformance audit conducted by an independent third-party auditor.

Based on the representations made in the covered country declarations regarding the supply chains upstream of Imperial's direct catalyst suppliers, together with information provided in further discussions with certain of these suppliers and information available on the RMI website, we do not believe further diligence regarding these supply chains is necessary on Imperial's part.
