(1)Earnings before interest, taxes, depreciation and amortization, which we refer to as “EBITDA,” is calculated as Net income attributable to HF Sinclair stockholders plus (i)Income tax expense, (ii)Interest expense, net of Interest income and (iii)Depreciation and amortization. EBITDA is not a calculation provided for under GAAP; however, the amounts included in the EBITDA calculation are derived from amounts included in our consolidated financial statements. EBITDA should not be considered as an alternative to Net income or Income from operations as an indication of our operating performance or as an alternative to operating cash flow as a measure of liquidity. EBITDA is not necessarily comparable to similarly titled measures of other companies. EBITDA is presented here because it is a financial indicator widely used by investors and analysts to measure performance. EBITDA is also used by our management for internal analysis and as a basis for financial covenants. EBITDA presented above is reconciled to Net income under “Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles” following Item 2 of Part I of this Quarterly Report on Form 10-Q.

Supplemental Segment Operating Data

Our operations are organized into five reportable segments, Refining, Renewables, Marketing, Lubricants & Specialties and Midstream. See Note 18 “Segment Information” in the Consolidated Financial Statements for additional information on our reportable segments.

Refining Segment Operating Data

The disaggregation of our refining geographic operating data is presented in two regions, Mid-Continent and West, to best reflect the economic drivers of our refining operations. The Mid-Continent region is comprised of the El Dorado and Tulsa refineries. The West region is comprised of the Puget Sound, Navajo, Woods Cross, Parco and Casper refineries. The following tables set forth information, including non-GAAP performance measures, about our consolidated refinery operations. Adjusted refinery gross margin per produced barrel sold is total Refining segment gross margin plus Lower of cost or market inventory valuation adjustments, Depreciation and amortization and Operating expenses, divided by sales volumes of produced refined products. This margin measure does not include the non-cash effects of Lower of cost or market inventory valuation adjustments, which relate to inventory held at the end of the period. Reconciliations to amounts reported under GAAP are provided under “Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles” following Item 2 of Part I of this Quarterly Report on Form 10-Q.

Results of Operations – Three Months Ended September 30, 2026 Compared to Three Months Ended September 30, 2025

Summary

Net income attributable to HF Sinclair stockholders for the three months ended September 30, 2026 was $2,015 million ($11.38 per basic and diluted share), a $1,612 million increase compared to $403 million ($2.15 per basic and diluted share) for the three months ended September 30, 2025. The increase in Net income attributable to HF Sinclair stockholders was principally driven by higher adjusted refinery gross margins in both the West and Mid-Continent regions. Adjusted refinery gross margin per produced barrel sold for the three months ended September 30, 2026 increased to $54.22 as compared to $19.16 for the three months ended September 30, 2025, primarily due to higher average sales prices per barrel and small refinery RINs waivers granted by the EPA, partially offset by higher crude oil and feedstock prices per barrel. Lower of cost or market inventory valuation adjustments decreased $96 million from a $66 million charge related to our Refining and Renewables segments’ inventories for the three months ended September 30, 2025, to a $30 million benefit related to our Renewables segment inventories for the three months ended September 30, 2026.

Adjusted renewables gross margin for the three months ended September 30, 2026 increased to $2.11 per produced gallon sold as compared to $0.18 for the three months ended September 30, 2025 primarily due to higher RINs prices and PTC benefits. These favorable impacts were partially offset by a $509 million increase in Income tax expenseand $109 million of additional costs and incremental accelerated depreciation and amortization charges recorded in relation to the Mississauga Asset Retirement.

Sales and Other Revenues

Sales and other revenues increased $3,606 million, or 50%, from $7,251 million for the three months ended September 30, 2025, to $10,857 million for the three months ended September 30, 2026, principally due to higher average refined product sales prices, partially offset by lower product sales volumes and higher crude oil and feedstock prices. Revenues from external customers during the third quarter of 2026 include $182 million, $1,576 million, $924 million and $34 million related to our Renewables, Marketing, Lubricants & Specialties and Midstream segments, respectively. Revenues from external customers included $163 million, $898 million, $654 million and $29 million related to our Renewables, Marketing, Lubricants & Specialties and Midstream segments for the three months ended September 30, 2025.

Cost of Materials and Other

Cost of materials and other, exclusive of Lower of cost or market inventory valuation adjustments, increased $1,320 million, or 23%, from $5,692 million for the three months ended September 30, 2025, to $7,012 million for the three months ended September 30, 2026, principally due to higher crude oil and feedstock costs which were offset by lower product sales volumes and the grant of small refinery RINs waivers. Within our Lubricants & Specialties segment, the FIFO impact resulted in a benefit of $22 million and $2 million for the three months ended September 30, 2026 and 2025, respectively.

During the third quarter of 2026, we recognized a lower of cost or market inventory valuation adjustment benefit of $30 million compared to a charge of $66 million during the third quarter of 2025.

Adjusted Refinery Gross Margin

Adjusted refinery gross margin per produced barrel sold increased $35.06, or 183%, from $19.16 for the three months ended September 30, 2025, to $54.22 for the three months ended September 30, 2026. The increase was primarily driven by improved crack spreads on refined products in both the Mid-Continent and West regions and the grant of small refinery RINs waivers, partially offset by lower product sales volumes for the three months ended September 30, 2026.

Adjusted refinery gross margin per produced barrel sold is a non-GAAP measure and excludes the non-cash effects of Lower of cost or market inventory valuation adjustment, Operating expenses, and Depreciation and amortization. Reconciliations to amounts reported under GAAP are provided under “Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles” following Item 2 of Part I of this Quarterly Report on Form 10-Q.

Operating Expenses

Operating expenses increased $133 million, or 23%, from $590 million for the three months ended September 30, 2025, to $723 million for the three months ended September 30, 2026, primarily due to higher employee benefits, maintenance, environmental remediation and other miscellaneous costs, partially offset by lower electricity and natural gas costs.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $41 million, or 39%, from $105 million for the three months ended September 30, 2025, to $146 million for the three months ended September 30, 2026, primarily due to higher employee benefits, professional services and other miscellaneous costs.

Depreciation and Amortization Expenses

Depreciation and amortization increased $48 million, or 21% from $230 million for the three months ended September 30, 2025 to $278 million for the three months ended September 30, 2026, primarily due to $54 million of incremental accelerated depreciation and amortization in connection with the Mississauga Asset Retirement. See Note 2 “Lubricants & Specialties Planned Separation and Mississauga Asset Retirement” in the Consolidated Financial Statements for information regarding the Mississauga Asset Retirement.

Other Operating Expenses, Net

Other operating expenses, net increased $52 million, or 1,300% from $4 million for the three months ended September 30, 2025, to $56 million for the three months ended September 30, 2026, primarily due to the abandonment of certain assets under construction at the Mississauga Refinery and severance costs in connection with the Mississauga Asset Retirement. See Note 2 “Lubricants & Specialties Planned Separation and Mississauga Asset Retirement” in the Consolidated Financial Statements for information regarding the Mississauga Asset Retirement.

Interest Income

Interest income increased $14 million, or 127%, from $11 million for the three months ended September 30, 2025, to $25 million for the three months ended September 30, 2026, primarily due to higher cash balances.

Interest Expense

Interest expense increased $3 million, or 6%, from $51 million for the three months ended September 30, 2025, to $54 million for the three months ended September 30, 2026, primarily due to unrealized losses on precious metals financing arrangements during the period.

Income Taxes

For the three months ended September 30, 2026, Income tax expense of $632 million was recorded on pre-tax income of $2,649 million, compared to Income tax expense of $123 million on pre-tax income of $528 million for the three months ended September 30, 2025. The increase was primarily due to higher pre-tax earnings year-over-year. For the three months ended September 30, 2026, the effective tax rate of 23.8% was higher than the statutory rate of 21.0%, primarily due to state and local income taxes on pre-tax earnings, partially offset by the benefits of nontaxable renewable fuel incentives. For the three months ended September 30, 2025, the effective tax rate was higher than the statutory rate of 21.0%, primarily due to pre-tax results and the effects of state and local income tax.

Results of Operations – Nine Months Ended September 30, 2026 Compared to Nine Months Ended September 30, 2025

Summary

Net income attributable to HF Sinclair stockholders for the nine months ended September 30, 2026, was $3,555 million ($19.75 per basic and diluted share), a $2,948 million increase compared to $607 million ($3.21 per basic and diluted share) for the nine months ended September 30, 2025. The increase in Net income attributable to HF Sinclair stockholders was principally driven by higher adjusted refinery gross margins in both the West and Mid-Continent regions. Adjusted refinery gross margin per produced barrel sold for the nine months ended September 30, 2026 increased to $30.12 as compared to $15.07 for the nine months ended September 30, 2025, primarily due to higher average sales prices per barrel and small refinery RINs waivers granted by the EPA, partially offset by higher crude oil and feedstock prices per barrel. Lower of cost or market inventory valuation adjustments related to our Refining and Renewables segments’ inventories decreased by $769 million, from a $97 million charge for the nine months ended September 30, 2025, to a $672 million benefit for the nine months ended September 30, 2026.

Adjusted renewables gross margin for the nine months ended September 30, 2026 increased to $2.48 per produced gallon sold as compared to $0.24 for the nine months ended September 30, 2025 primarily due to higher RINs pricing, PTC benefits and higher sales volumes, compared to the nine months ended September 30, 2025. These favorable impacts were partially offset by a $940 million increase in Income tax expense and $109 million of additional costs and incremental accelerated depreciation and amortization charges recorded in relation to the Mississauga Asset Retirement.
