Dallas, Texas, July 31, 2025 ‑ HF Sinclair Corporation (NYSE and NYSE Texas, Inc.: DINO) (“HF Sinclair” or the “Company”) today reported Net income attributable to HF Sinclair stockholders of $208 million, or $1.10 per diluted share, for the quarter ended June 30, 2025, compared to Net income attributable to HF Sinclair stockholders of $152 million, or $0.79 per diluted share, for the quarter ended June 30, 2024. Excluding the adjustments shown in the accompanying earnings release table, adjusted net income attributable to HF Sinclair stockholders for the second quarter of 2025 was $322 million, or $1.70 per diluted share, compared to adjusted net income attributable to HF Sinclair stockholders of $150 million, or $0.78 per diluted share, for the second quarter of 2024.

HF Sinclair’s Chief Executive Officer, Tim Go, commented, “During the second quarter of 2025, we made strong progress on our key priorities to improve reliability, optimization and integration, and I’m pleased to report we delivered sequential improvements over the last three quarters in refining throughput, capture and lower operating costs – allowing us to return $145 million to stockholders through dividend and share repurchases in the current period. Looking forward, we remain focused on advancing these priorities further, and with the majority of our turnarounds behind us in 2025, we believe we are well positioned to continue to execute our strategy and return excess cash to our shareholders.”

Refining segment income before interest and income taxes was $166 million for the second quarter of 2025 compared to income of $65 million for the second quarter of 2024. Excluding the Lower of cost or market inventory valuation adjustment charge of $172 million and certain items, the segment reported Adjusted EBITDA of $476 million for the second quarter of 2025 compared to $187 million for the second quarter of 2024. This increase was principally driven by higher adjusted refinery gross margins in both the West and Mid-Continent regions partially offset by lower refined product sales volumes. Adjusted refinery gross margin was $16.50 per produced barrel sold, a 46% increase compared to $11.33 for the second quarter of 2024. Crude oil charge averaged 615,930 barrels per day (“BPD”) for the second quarter of 2025 compared to 634,730 BPD for the second quarter of 2024. This decrease was primarily a result of turnaround activities at our Tulsa and Parco refineries during the second quarter of 2025.

Renewables segment loss before interest and income taxes was $4 million for the second quarter of 2025 compared to a loss of $15 million for the second quarter of 2024. Excluding the Lower of cost or market inventory valuation adjustment benefit of $24 million, the segment reported Adjusted EBITDA of $(2) million in the second quarter of 2025 compared to $2 million in the second quarter of 2024. In the second quarter of 2025 we began partially recognizing the benefits from the Producer’s Tax Credit, and we expect to capture additional incremental value in the third quarter of 2025. Total sales volumes were 55 million gallons for the second quarter of 2025 compared to 64 million gallons for the second quarter of 2024.

Marketing segment income before interest and income taxes was $18 million for the second quarter of 2025 compared to $9 million for the second quarter of 2024. The segment reported EBITDA of $25 million for the second quarter of 2025 compared to $15 million for the second quarter of 2024. This increase was primarily driven by higher margins and high-grading our mix of stores in the second quarter of 2025. Total branded fuel sales volumes were 337 million gallons for the second quarter 2025 as compared to 357 million gallons for the second quarter of 2024.

Lubricants & Specialties segment income before interest and income taxes was $33 million for the second quarter of 2025 compared to $74 million in the second quarter of 2024. The segment reported EBITDA of $55 million for the second quarter of 2025 compared to $97 million in the second quarter of 2024. The decrease was primarily driven by lower margins in addition to lower sales volumes as a result of turnaround activities at our Mississauga facility. During the second quarter of 2025, we recognized a FIFO charge of $20 million compared to a FIFO charge of $14 million during the second quarter of 2024.

Midstream segment income before interest and income taxes was $98 million for the second quarter of 2025 compared to $97 million for the second quarter of 2024. Excluding certain items, the segment reported Adjusted EBITDA of $112 million for the second quarter of 2025 compared to $110 million for the second quarter of 2024. This increase was primarily driven by higher pipeline revenues and lower operating expenses, partially offset by lower throughput volumes in the second quarter of 2025 as compared to the second quarter of 2024.

For the second quarter of 2025, net cash provided by operations totaled $587 million. At June 30, 2025, the Company’s Cash and cash equivalents totaled $874 million, a $74 million increase compared to Cash and cash equivalents of $800 million at December 31, 2024.

Earnings before interest, taxes, depreciation and amortization, referred to as EBITDA, is calculated as Net income attributable to HF Sinclair stockholders plus (i) Interest expense, net of Interest income, (ii) Income tax expense and (iii) Depreciation and amortization. Adjusted EBITDA is calculated as EBITDA plus or minus (i) Lower of cost or market inventory valuation adjustments, (ii) loss on sale of equity method investment (iii) loss on early extinguishment of debt, (iv) decommissioning and closure costs, (v) asset impairments and (vi) acquisition integration costs.

EBITDA and Adjusted EBITDA are not calculations provided for under accounting principles generally accepted in the United States; however, the amounts included in these calculations are derived from amounts included in our consolidated financial statements. EBITDA and Adjusted EBITDA should not be considered as alternatives 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 and Adjusted EBITDA are not necessarily comparable to similarly titled measures of other companies. These are presented here because they are financial indicators widely used by investors and analysts to measure our operating performance. EBITDA and Adjusted EBITDA are also used by our management for internal analysis and as a basis for financial covenants.

Set forth below is our calculation of EBITDA and Adjusted EBITDA:

(1)Net of certain unrelated costs and benefits in our Refining segment and Midstream segment, respectively.

EBITDA and Adjusted EBITDA attributable to our Refining segment are presented below:

(1)Income before interest and income taxes of our Refining segment represents income plus (i) Interest expense, net of Interest income and (ii) Income tax expense.

EBITDA and Adjusted EBITDA attributable to our Renewables segment are set forth below:

(1)Loss before interest and income taxes of our Renewables segment represents loss plus (i) Interest expense, net of Interest income and (ii) Income tax expense.

EBITDA attributable to our Marketing segment is set forth below:

(1)Income before interest and income taxes of our Marketing segment represents income plus (i) Interest expense, net of Interest income and (ii) Income tax expense.

EBITDA attributable to our Lubricants & Specialties segment is set forth below:

(1)Income before interest and income taxes of our Lubricants & Specialties segment represents income plus (i) Interest expense, net of Interest income and (ii) Income tax expense.

EBITDA and Adjusted EBITDA attributable to our Midstream segment are presented below:

(1)Income before interest and income taxes of our Midstream segment represents income plus (i) Interest expense, net of Interest income and (ii) Income tax expense.

Adjusted refinery gross margin is a non-GAAP performance measure that is used by our management and others to compare our refining performance to that of other companies in our industry. We believe this margin measure is helpful to investors in evaluating our refining performance on a relative and absolute basis, including against publicly available crack spread data. Adjusted refinery gross margin per produced barrel sold is total Refining segment gross margin plus Lower of cost or market inventory valuation adjustments, Operating expenses and Depreciation and amortization, 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. Adjusted refinery gross margin is a non-GAAP performance measure and should not be considered in isolation or as a substitute for Refining segment gross margin. The GAAP measure most directly comparable to adjusted refinery gross margin is Refining segment gross margin. Other companies in our industry may not calculate these performance measures in the same manner. Due to rounding of reported numbers, some amounts may not calculate exactly.

Reconciliation of Refining segment gross margin to adjusted refinery gross margin to adjusted refinery gross margin per produced barrel sold and adjusted refinery gross margin, less operating expenses per produced barrel sold
