Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Description of Business: References herein to HF Sinclair Corporation (“HF Sinclair” or the “Company”) include HF Sinclair and its consolidated subsidiaries. In these interim consolidated financial statements, the words “we,” “our,” “ours” and “us” refer only to HF Sinclair and its consolidated subsidiaries or, in certain contexts, to HF Sinclair or an individual consolidated subsidiary and not to any other person, with certain exceptions. We are an independent energy company that produces and markets high-value light products such as gasoline, diesel fuel, jet fuel, renewable diesel and lubricants and specialty products. We own and operate refineries located in Kansas, Oklahoma, New Mexico, Wyoming, Washington and Utah. We provide petroleum product and crude oil transportation, terminalling, storage and throughput services to our refineries and the petroleum industry. We market our refined products principally in the Southwest United States, the Rocky Mountains extending into the Pacific Northwest and in other neighboring Plains states, and we supply high-quality fuels to more than 1,800 branded stations and license the use of the Sinclair brand to more than 350 additional locations throughout the country. We produce renewable diesel at two of our facilities in Wyoming and one facility in New Mexico. In addition, we produce and market base oils and other specialized lubricants in the United States, Canada and the Netherlands, and export products to more than 80 countries. On July 28, 2026, we announced the decision to retire our Mississauga, Ontario base oil refining assets, with the transition expected to be substantially completed by the second half of 2027. Industrial Oils Unlimited Acquisition In January 2026, we acquired Industrial Oils Unlimited for a total consideration of $40 million. Total cash paid for the net identifiable assets recognized, net of cash acquired, was $38 million. Industrial Oils Unlimited is a producer of high-quality lubricants and specialty fluids with blending facilities in Tulsa, Oklahoma; Shreveport, Louisiana; and Little Rock and Fort Smith, Arkansas, as well as warehousing and terminal facilities in Pampa and Midland, Texas. This transaction was accounted for as a business combination using the acquisition method of accounting, with the purchase price allocated to the fair value of the acquired assets and liabilities as of the acquisition date. Basis of Presentation: The interim consolidated financial statements are unaudited. In management’s opinion, these interim consolidated financial statements include all normal recurring adjustments necessary for a fair presentation and have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and with the rules and regulations of the Securities and Exchange Commission (“SEC”). We believe that the disclosures in these interim consolidated financial statements are adequate to make the information presented not misleading. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the entire year. These interim unaudited consolidated financial statements with the notes herein have been condensed and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2025 that was filed with the SEC on February 27, 2026. Accounting Pronouncements (Recently Adopted): In July 2025, ASU 2025-05, “Measurement of Credit Losses for Accounts Receivable and Contract Assets” was issued and offers a new optional practical expedient related to the estimation of future expected credit losses on accounts receivable. We adopted this ASU on a prospective basis, effective January 1, 2026, and it did not have a material impact on our interim consolidated financial statements and disclosures. Accounting Pronouncements (Not Yet Adopted): In November 2024, ASU 2024-03, “Disaggregation of Income Statement Expenses” was issued. ASU 2024-03 requires companies to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026 and for interim periods beginning after December 15, 2027, and may be adopted on a prospective or retrospective basis. Early adoption is permitted. The adoption will not affect our financial position or our results of operations, but will result in additional disclosures.

ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, with early adoption permitted. We are currently assessing the impact of this guidance on our consolidated financial statements. In May 2026, ASU 2026-02, “Environmental Credits and Environmental Credit Obligations” was issued.
