• Reported Net income attributable to HF Sinclair stockholders of $648 million, or $3.56 per diluted share, and adjusted net income attributable to HF Sinclair stockholders of $127 million, or $0.69 per diluted share
• Reported EBITDA of $1,097 million and Adjusted EBITDA of $426 million
• Returned $167 million to stockholders through dividends and share repurchases in the first quarter

HF Sinclair Corporation (NYSE and NYSE Texas, Inc.: DINO) (“HF Sinclair” or the “Company”) today reported Net income attributable to HF Sinclair stockholders of $648 million, or $3.56 per diluted share, for the quarter ended March 31, 2026, compared to Net loss attributable to HF Sinclair stockholders of $4 million, or $(0.02) per diluted share, for the quarter ended March 31, 2025. Excluding the adjustments shown in the accompanying earnings release table, adjusted net income attributable to HF Sinclair stockholders for the first quarter of 2026 was $127 million, or $0.69 per diluted share, compared to adjusted net loss attributable to HF Sinclair stockholders of $50 million, or $(0.27) per diluted share, for the first quarter of 2025.

HF Sinclair’s Chief Executive Officer, Franklin Myers, commented, “During the quarter, we delivered strong results across each of our business segments supported by safe and reliable operations. Looking forward, we remain focused on the execution of our strategic priorities and believe each of our business segments is well positioned to take advantage of the current favorable macroeconomic backdrop.”

Refining segment income before interest and income taxes was $514 million for the first quarter of 2026 compared to a loss of $30 million for the first quarter of 2025. Excluding the Lower of cost or market inventory valuation adjustment benefit of $604 million, the segment reported Adjusted EBITDA of $55 million for the first quarter of 2026 compared to $(8) million for the first quarter of 2025. This increase was principally driven by higher adjusted refinery gross margins in the West region and increased refined product sales volumes, partially offset by lower adjusted refinery gross margins in the Mid-Continent region. Small refinery RINs waivers granted by the EPA in the fourth quarter of 2025 increased adjusted refinery gross margins by $21 million in the first quarter of 2026. Adjusted refinery gross margin was $9.95 per produced barrel sold, a 9% increase compared to $9.12 for the first quarter of 2025. Crude oil charge averaged 613,050 barrels per day (“BPD”) for the first quarter of 2026 compared to 606,140 BPD for the first quarter of 2025.

Renewables segment income before interest and income taxes was $182 million for the first quarter of 2026 compared to a loss of $39 million for the first quarter of 2025. Excluding the Lower of cost or market inventory valuation adjustment benefit of $68 million, the segment reported Adjusted EBITDA of $133 million in the first quarter of 2026, compared to $(17) million in the first quarter of 2025. This increase was principally driven by higher adjusted renewables gross margins and increased sales volumes in the first quarter of 2026. Adjusted renewables gross margins increased as a result of the narrowing of the BOHO spread, higher RINs prices and the recognition of significantly more in Producer’s Tax Credit (“PTC”) benefits compared to the first quarter of 2025. Results for the first quarter of 2026 include prior year PTC benefits of $49 million that were recognized following the February 2026 proposed ruling by the United States Department of the Treasury and Internal Revenue Service. Total sales volumes were 52 million gallons for the first quarter of 2026 compared to 44 million gallons for the first quarter of 2025.

Marketing segment income before interest and income taxes was $20 million for the first quarter of 2026, consistent with the first quarter of 2025. The segment reported EBITDA of $28 million for the first quarter of 2026 compared to $27 million for the first quarter of 2025. Total branded fuel sales volumes were 325 million gallons for the first quarter of 2026 compared to 294 million gallons for the first quarter of 2025.

Lubricants & Specialties segment income before interest and income taxes was $78 million for the first quarter of 2026 compared to $63 million in the first quarter of 2025. The segment reported Adjusted EBITDA of $103 million for the first quarter of 2026 compared to $85 million in the first quarter of 2025. The increase was primarily driven by a larger FIFO benefit in the first quarter of 2026 compared to the first quarter of 2025, partially offset by the dislocation between rising feedstock costs and product sales price increases. During the first quarter of 2026, we recognized a FIFO benefit of $53 million compared to a FIFO benefit of $8 million during the first quarter of 2025.

Midstream segment income before interest and income taxes was $94 million for the first quarter of 2026 compared to $63 million for the first quarter of 2025. The segment reported Adjusted EBITDA of $111 million for the first quarter of 2026 compared to $119 million for the first quarter of 2025. The decrease was primarily driven by an increase in operating costs as a result of a fuel-contamination incident at one of our product terminals in Colorado in the first quarter of 2026.

For the first quarter of 2026, net cash provided by operations totaled $457 million. At March 31, 2026, the Company’s Cash and cash equivalents totaled $1,148 million, a $170 million increase compared to Cash and cash equivalents of $978 million at December 31, 2025. During the first quarter of 2026, the Company announced and paid a regular dividend of $0.50 per share to stockholders totaling $91 million and spent $76 million on share repurchases. Additionally, at March 31, 2026, the Company’s consolidated debt was $2,771 million.

HF Sinclair also announced today that its Board of Directors declared a regular quarterly dividend in the amount of $0.50 per share. The dividend is payable on June 2, 2026 to holders of record of common stock on May 11, 2026.

Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles

Reconciliations of earnings before interest, taxes, depreciation and amortization (“EBITDA”) and EBITDA excluding special items (“Adjusted EBITDA”) to amounts reported under generally accepted accounting principles (“GAAP”) in the financial statements.

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

The Company cannot reliably predict or estimate certain items or expenses, or their impact on financial statements in future periods. Accordingly, the Company believes that a reconciliation of non-GAAP financial measures to the equivalent GAAP financial measures for projected results is not meaningful or available without unreasonable effort.

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

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

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

EBITDA attributable to our Marketing segment is set forth below:

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

Reconciliation of refinery operating information (non-GAAP performance measures) to amounts reported under generally accepted accounting principles in the financial statements.

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 excludes 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

Reconciliation of renewables operating information (non-GAAP performance measures) to amounts reported under generally accepted accounting principles in the financial statements.

Adjusted renewables gross margin is a non-GAAP performance measure that is used by our management and others to compare our renewables performance to that of other companies in our industry. We believe this margin measure is helpful to investors in evaluating our renewables performance on a relative and absolute basis. Adjusted renewables gross margin per produced gallon sold is total Renewables segment gross margin plus Lower of cost or market inventory valuation adjustments, Operating expenses and Depreciation and amortization, divided by sales volumes of produced renewables products. This margin measure excludes the non-cash effects of Lower of cost or market inventory valuation adjustments, which relate to volumes in inventory at the end of the period. Adjusted renewables gross margin is not a calculation provided for under GAAP and should not be considered in isolation or as a substitute for Renewables segment gross margin. The GAAP measure most directly comparable to adjusted renewables gross margin is Renewables 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.
