The audit of the Company's financial statements for 2025 is not yet complete, as the Company's Audit Committee is engaged (as discussed below) in assessing certain matters relating to the Company's disclosure processes. Accordingly, all results discussed in this release are unaudited. The Audit Committee has determined that these matters under review do not affect the results for the fourth quarter of 2025 or for full-year 2025 announced in this release.

HF Sinclair Corporation (NYSE and NYSE Texas, Inc.: DINO) ("HF Sinclair" or the "Company") today reported fourth quarter Net loss attributable to HF Sinclair stockholders of $28 million, or $(0.16) per diluted share, for the quarter ended December 31, 2025, compared to Net loss attributable to HF Sinclair stockholders of $214 million, or $(1.14) per diluted share, for the quarter ended December 31, 2024. Excluding the adjustments shown in the accompanying earnings release table, adjusted net income attributable to HF Sinclair stockholders for the fourth quarter of 2025 was $221 million, or $1.20 per diluted share, compared to adjusted net loss attributable to HF Sinclair stockholders of $191 million, or $(1.02) per diluted share, for the fourth quarter of 2024.

As separately announced this morning, HF Sinclair's Chief Executive Officer and President, Tim Go, is taking a voluntary leave of absence from his duties, and the Board of Directors (the "Board") has appointed Mr. Franklin Myers as Chief Executive Officer and President on a temporary basis. Mr. Myers also continues to serve as Chairperson of the Board.

The Company's fourth quarter results reflect seasonal weakness in refining cracks, along with the Puget Sound Refinery turnaround and the unplanned Artesia refinery event. For full-year 2025, the Company achieved record earnings in both its Midstream and Marketing businesses and achieved the Company's lowest annual refining operating expense per barrel. During the year, the Company also returned over $724 million in cash to shareholders through share repurchases and dividends, and today, the Company announced a $0.50 regular quarterly dividend. Looking forward, the Company remains focused on safe and reliable operations, continued growth in its Midstream, Lubricants and Marketing segments and returning excess cash to the Company's shareholders.

Refining segment loss before interest and income taxes was $49 million for the fourth quarter of 2025 compared to a loss of $332 million for the fourth quarter of 2024. Excluding the Lower of cost or market inventory valuation adjustment charge of $313 million and certain items, the segment reported Adjusted EBITDA of $403 million for the fourth quarter of 2025 compared to $(169) million for the fourth 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 the Puget Sound refinery planned turnaround and the unplanned Artesia refinery event. Small refinery RINs waivers granted by the EPA increased adjusted refinery gross margins by $313 million in the fourth quarter of 2025, which includes $43 million of benefits related to the small refinery RINs waivers received in the third quarter but recognized in the fourth quarter of 2025. Adjusted refinery gross margin was $16.28 per produced barrel sold, a 144% increase compared to $6.68 for the fourth quarter of 2024. Crude oil charge averaged 556,460 barrels per day ("BPD") for the fourth quarter of 2025 compared to 562,020 BPD for the fourth quarter of 2024.

Renewables segment loss before interest and income taxes was $35 million for the fourth quarter of 2025 compared to a loss of $13 million for the fourth quarter of 2024. Excluding the Lower of cost or market inventory valuation adjustment charge of $7 million, the segment reported Adjusted EBITDA of $(6) million in the fourth quarter of 2025 compared to $(9) million in the fourth quarter of 2024. In the fourth quarter of 2025 we recognized incrementally more in value from the Producer's Tax Credit. Total sales volumes were 57 million gallons for the fourth quarter of 2025 compared to 62 million gallons for the fourth quarter of 2024.

Marketing segment income before interest and income taxes was $14 million for the fourth quarter of 2025 compared to $13 million for the fourth quarter of 2024. The segment reported EBITDA of $22 million for the fourth quarter of 2025 compared to $21 million for the fourth quarter of 2024. This increase was primarily driven by higher margins and high-grading our mix of stores throughout 2025. Total branded fuel sales volumes were 337 million gallons for the fourth quarter of 2025 compared to 333 million gallons for the fourth quarter of 2024.

Lubricants & Specialties segment income before interest and income taxes was $19 million for the fourth quarter of 2025 compared to $46 million in the fourth quarter of 2024. The segment reported EBITDA of $43 million for the fourth quarter of 2025 compared to Adjusted EBITDA of $70 million in the fourth quarter of 2024. The decrease was primarily driven by lower finished and specialty product sales volumes, lower base oil margins and higher operating expenses.

Midstream segment income before interest and income taxes was $96 million for the fourth quarter of 2025 compared to $97 million for the fourth quarter of 2024. The segment reported EBITDA of $114 million for the fourth quarter of 2025, consistent with the fourth quarter of 2024.

For the fourth quarter of 2025, net cash provided by operations totaled $8 million. At December 31, 2025, the Company's Cash and cash equivalents totaled $978 million, a $178 million increase compared to Cash and cash equivalents of $800 million at December 31, 2024. During the fourth quarter of 2025, the Company announced and paid a regular dividend of $0.50 per share to stockholders totaling $92 million and spent $138 million on share repurchases. Additionally, at December 31, 2025, the Company's consolidated debt was $2,769 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 March 12, 2026 to holders of record of common stock on March 2, 2026.

The Company has scheduled a webcast conference call for today, February 18, 2026, at 8:30 AM Eastern Time to discuss fourth quarter financial results. This webcast may be accessed at: https://events.q4inc.com/attendee/560135108. An audio archive of this webcast will be available using the above noted link through March 4, 2026.

The Company will not be filing its Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the "Form 10-K") today, given that the Audit Committee of the Board is in the process of assessing certain matters relating to the Company's disclosure processes. The Audit Committee has determined that these matters do not affect the results for the fourth quarter of 2025 or for full-year 2025 announced in this release. The Audit Committee and all other parties are working diligently to complete this review as soon as possible. The Company will file its Form 10-K following completion of the audit process. At the present time, the Company expects that it will be able to timely file its Form 10-K.
