HF Sinclair’s Chief Executive Officer, Franklin Myers, commented, “During the quarter, we delivered strong financial results across each of our business segments, underpinned by strong operational and commercial execution. We returned $265 million to stockholders through dividends and share repurchases and today we also announced a 5% increase to our quarterly dividend, demonstrating our continued commitment to return capital to shareholders.

The segment reported Adjusted EBITDA of $1,023 million for the second quarter of 2026 compared to $476 million for the second quarter of 2025.

Adjusted renewables gross margins increased as a result of improved RINs prices, higher Producer’s Tax Credit (“PTC”) benefits and increased volumes compared to the second quarter of 2025. Total sales volumes were 60 million gallons for the second quarter of 2026 compared to 55 million gallons for the second quarter of 2025.

Refining Segment Operating Data The following tables set forth information, including non-GAAP (generally accepted accounting principles) 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” below. 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.

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 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) asset impairments, (iii) loss on sale of equity method investment, (iv) loss on early extinguishment of debt, (v) decommissioning and closure costs and (vi) 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: Three Months Ended June 30,Six Months Ended June 30, 2026 2025 2026 2025 (In millions) Net income attributable to HF Sinclair stockholders $ 892 $ 208 $ 1,540 $ 204 Add: interest expense 20 53 61 102 Less: interest income (15) (7) (25) (16) Add: income tax expense 279 36 468 37 Add: depreciation and amortization 228 226 457 451 EBITDA $ 1,404 $ 516 $ 2,501 $ 778 Add: lower of cost or market inventory valuation adjustments 30 148 (642) 31 Add: asset impairments 47 — 47 1 Add: loss on sale of equity method investment — — — 40 Add: loss on early extinguishment of debt — 1 — 16 Add: decommissioning and closure costs — — — — Add: acquisition integration and regulatory costs 1 — 2 — Adjusted EBITDA $ 1,482 $ 665 $ 1,908 $ 866 (1) Net of certain unrelated costs of $4 million in the Refining segment by $4 million benefits in the Midstream segment, respectively.

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.
