References herein to HF Sinclair Corporation ("HF Sinclair") include HF Sinclair and its consolidated subsidiaries. In this document, the words "we," "our," "ours" and "us" refer only to HF Sinclair and its consolidated subsidiaries or to HF Sinclair or an individual subsidiary and not to any other person, with certain exceptions.

This Quarterly Report on Form 10-Q contains certain "forward-looking statements" within the meaning of the federal securities laws. All statements, other than statements of historical fact included in this Quarterly Report on Form 10-Q, including, but not limited to, those under "Overview," "Results of Operations," "Liquidity and Capital Resources" and "Risk Management" in Part I, Item 2 "Management's Discussion and Analysis of Financial Condition and Results of Operations" and those in Part II, Item 1 "Legal Proceedings" are forward-looking statements. Forward-looking statements use words such as "anticipate," "project," "will," "expect," "plan," "goal," "forecast," "strategy," "intend," "should," "would," "could," "believe," "may," and similar expressions and statements regarding our plans and objectives for future operations. These statements are based on management's beliefs and assumptions using currently available information and expectations as of the date hereof, are not guarantees of future performance and involve certain risks and uncertainties. All statements concerning our expectations for future results of operations are based on forecasts for our existing operations and do not include the potential impact of any future acquisitions. Although we believe that the expectations reflected in these forward-looking statements are reasonable, we cannot assure you that our expectations will prove to be correct. Therefore, actual outcomes and results could materially differ from what is expressed, implied or forecast in these statements. Any differences could be caused by a number of factors including, but not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;• the demand for and supply of feedstocks, crude oil and refined products, including uncertainty regarding societal expectations that companies address climate impacts and greenhouse gas emissions;

&nbsp;&nbsp;&nbsp;&nbsp;• risks and uncertainties with respect to the actions of actual or potential competitive suppliers and transporters of refined petroleum products or lubricant and specialty products in our markets;

&nbsp;&nbsp;&nbsp;&nbsp;• the spread between market prices for refined products and market prices for crude oil;

&nbsp;&nbsp;&nbsp;&nbsp;• the possibility of constraints on the transportation of crude oil, refined products or lubricant and specialty products;

&nbsp;&nbsp;&nbsp;&nbsp;• the possibility of inefficiencies, curtailments or shutdowns in refinery or other production facility operations or pipelines, whether due to reductions in demand, accidents, unexpected leaks or spills, unscheduled shutdowns, infection in the workforce, weather events, global health events, civil unrest, expropriation of assets, and other economic, diplomatic, legislative, or political events or developments, terrorism, cyberattacks, vandalism or other catastrophes or disruptions affecting our operations, production facilities, machinery, pipelines and other logistics assets, equipment, or information systems, or any of the foregoing at our suppliers, customers, or third-party providers, and any potential asset impairments resulting from, or the failure to have adequate insurance coverage for or receive insurance recoveries from, such actions;

&nbsp;&nbsp;&nbsp;&nbsp;• the effects of current and/or future governmental and environmental regulations and policies, including compliance with, or exemptions from, existing, new and changing environmental, health and safety laws and regulations, related reporting requirements and pipeline integrity programs;

&nbsp;&nbsp;&nbsp;&nbsp;• the availability and cost of our financing;

&nbsp;&nbsp;&nbsp;&nbsp;• the effectiveness of our capital investments and marketing strategies;

&nbsp;&nbsp;&nbsp;&nbsp;• our efficiency in carrying out and consummating construction projects, including our ability to complete announced capital projects on time and within capital guidance;

&nbsp;&nbsp;&nbsp;&nbsp;• our ability to timely obtain or maintain permits, including those necessary for operations or capital projects;

&nbsp;&nbsp;&nbsp;&nbsp;• our ability to acquire complementary assets or businesses to our existing assets and businesses on acceptable terms and to integrate any existing or future acquired operations and realize the expected synergies of any such transaction on the expected timeline;

&nbsp;&nbsp;&nbsp;&nbsp;• the possibility of vandalism or other disruptive activity, or terrorist or cyberattacks, and the consequences of any such activities or attacks;

&nbsp;&nbsp;&nbsp;&nbsp;• uncertainty regarding the effects and duration of global hostilities, war or any associated military campaigns, including those in oil producing regions, such as the ongoing military conflict in the Middle East, which may disrupt crude oil supplies and markets for our refined products and create instability in the financial markets that could restrict our ability to raise capital;

&nbsp;&nbsp;&nbsp;&nbsp;• general economic conditions, including uncertainties regarding trade policies, such as the imposition or implementation of tariffs, or economic slowdowns caused by a local or national recession or other adverse economic conditions, such as periods of increased or prolonged inflation;

&nbsp;&nbsp;&nbsp;&nbsp;• limitations on our ability to make future dividend payments or effectuate share repurchases due to market conditions and corporate, tax, regulatory and other considerations; and

&nbsp;&nbsp;&nbsp;&nbsp;• other business, financial, operational and legal risks and uncertainties detailed from time to time in our Securities and Exchange Commission filings.

**HF SINCLAIR CORPORATION**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(Unaudited)**

**NOTE 1:Description of Business and Basis of Presentation**

***Description of Business:*** References herein to HF Sinclair Corporation ("HF Sinclair" or the "Company") include HF Sinclair and its consolidated subsidiaries. In these interim consolidated financial statements, the words "we," "our," "ours" and "us" refer only to HF Sinclair and its consolidated subsidiaries or, in certain contexts, to HF Sinclair or an individual consolidated subsidiary and not to any other person, with certain exceptions.

We are an independent energy company that produces and markets high-value light products such as gasoline, diesel fuel, jet fuel, renewable diesel and lubricants and specialty products. We own and operate refineries located in Kansas, Oklahoma, New Mexico, Wyoming, Washington and Utah. We provide petroleum product and crude oil transportation, terminalling, storage and throughput services to our refineries and the petroleum industry. We market our refined products principally in the Southwest United States, the Rocky Mountains extending into the Pacific Northwest and in other neighboring Plains states, and we supply high-quality fuels to more than 1,750 branded stations and license the use of the Sinclair brand to more than 350 additional locations throughout the country. We produce renewable diesel at two of our facilities in Wyoming and one facility in New Mexico. In addition, our subsidiaries produce and market base oils and other specialized lubricants in the United States, Canada and the Netherlands, and export products to more than 80 countries.

***Industrial Oils Unlimited Acquisition***

In January 2026, we acquired Industrial Oils Unlimited for $38 million. Industrial Oils Unlimited is a producer of high-quality lubricants and specialty fluids with blending facilities in Tulsa, Oklahoma; Shreveport, Louisiana; and Little Rock and Fort Smith, Arkansas, as well as warehousing and terminal facilities in Pampa and Midland, Texas.

This transaction was accounted for as a business combination using the acquisition method of accounting, with the purchase price allocated to the fair value of the acquired Industrial Oils Unlimited assets and liabilities as of the acquisition date.

***Basis of Presentation:*** The interim consolidated financial statements are unaudited. In management's opinion, these interim consolidated financial statements include all normal recurring adjustments necessary for a fair presentation and have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") and with the rules and regulations of the Securities and Exchange Commission ("SEC"). We believe that the disclosures in these interim consolidated financial statements are adequate to make the information presented not misleading. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the entire year. These interim unaudited consolidated financial statements with the notes herein have been condensed and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2025 that was filed with the SEC on February 27, 2026.

***Accounting Pronouncements (Recently Adopted):*** In July 2025, ASU 2025-05, "Measurement of Credit Losses for Accounts Receivable and Contract Assets" was issued and offers a new optional practical expedient related to the estimation of future expected credit losses on accounts receivable. We adopted this ASU on a prospective basis, effective January 1, 2026, and it did not have a material impact on our interim consolidated financial statements and disclosures.

***Accounting Pronouncements (Not Yet Adopted):*** In November 2024, ASU 2024-03, "Disaggregation of Income Statement Expenses" was issued. ASU 2024-03 requires companies to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026 and for interim periods beginning after December 15, 2027, and may be adopted on a prospective or retrospective basis. Early adoption is permitted. The adoption will not affect our financial position or our results of operations, but will result in additional disclosures.

In September 2025, ASU 2025-06, "Internal-Use Software" was issued amending guidance related to the accounting for internal-use software development costs. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, with early adoption permitted. We are currently assessing the impact of this guidance on the consolidated financial statements.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(Unaudited)**

**NOTE 2:Cushing Connect Joint Venture**

We, through our wholly owned subsidiary HEP Cushing LLC ("HEP Cushing"), own a 50% interest in Cushing Connect Pipeline & Terminal LLC ("Cushing Connect"), a joint venture with Plains Marketing, L.P., a wholly owned subsidiary of Plains All American Pipeline, L.P. ("Plains"). Cushing Connect consists of (i) a 160,000 barrels per day common carrier crude oil pipeline (the "Cushing Connect Pipeline") that connects the Cushing, Oklahoma crude oil hub to our Tulsa refineries, and (ii) the ownership and operation of 1.5 million barrels of crude oil storage in Cushing, Oklahoma (the "Cushing Connect Terminal").

Cushing Connect entered into contracts with an affiliate of Holly Energy Partners, L.P. ("HEP"), a subsidiary of HF Sinclair, to manage the operation of the Cushing Connect Pipeline and with an affiliate of Plains to manage the operation of the Cushing Connect Terminal. The total investment in Cushing Connect was generally shared proportionately among the partners.

Cushing Connect and its two subsidiaries (the "Cushing Connect Entities") are variable interest entities because they lack sufficient equity at risk to finance their activities without additional financial support. We are the primary beneficiary of two of these entities as the affiliate of HEP owns and operates the Cushing Connect Pipeline, and we have the ability to direct the activities that most significantly impact the financial performance of Cushing Connect and the Cushing Connect Pipeline. Therefore, we consolidate Cushing Connect and the related Cushing Connect Pipeline subsidiary. We are not the primary beneficiary of the Cushing Connect Terminal, which we account for using the equity method of accounting. Our maximum exposure to loss as a result of our involvement with Cushing Connect Terminal is not expected to be material due to the long-term terminalling agreements in place to support operations.

With the exception of the assets of HEP Cushing, creditors of the Cushing Connect Entities have no recourse to our assets. Any recourse to HEP Cushing would be limited to the extent of HEP Cushing's assets, which, other than its investment in Cushing Connect, are not significant. Furthermore, our creditors have no recourse to the assets of the Cushing Connect Entities. The most significant assets of Cushing Connect and the Cushing Connect Pipeline that are available to settle only their obligations, and their most significant liabilities, for which creditors do not have recourse to our general credit, were as follows:

**NOTE 5:Fair Value Measurements**

Fair value measurements are derived using inputs (assumptions that market participants would use in pricing an asset or liability, including assumptions about risk). GAAP categorizes inputs used in fair value measurements into three broad levels as follows:

---

| | |
|:---|:---|
| Level 1: | Quoted prices in active markets for identical assets or liabilities. |
| Level 2: | Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, similar assets and liabilities in markets that are not active or can be corroborated by observable market data. |
| Level 3: | Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes valuation techniques that involve significant unobservable inputs. |

***Level 1 Fair Value Measurements:*** Our futures contracts based on New York Mercantile Exchange ("NYMEX") pricing are measured and recorded at fair value using quoted market prices, a Level 1 input.

***Level 2 Fair Value Measurements:*** Derivative instruments consisting of foreign currency forward contracts, commodity price swaps, and forward sales and purchase contracts are measured and recorded at fair value using Level 2 inputs. The fair value of foreign currency forward contracts is derived using market quotes for similar types of instruments. The fair value of the commodity price swap contracts is based on the net present value of expected future cash flows related to both variable and fixed rate legs of the respective swap agreements. The measurements are computed using market-based observable inputs and quoted forward commodity prices with respect to our commodity price swaps. The fair value of the forward sales and purchase contracts is computed using quoted forward commodity prices. The fair value of our precious metals financing arrangements, discussed in Note 11, is computed using quoted forward commodity prices. Environmental credit obligations are valued based on quoted prices from an independent pricing service.

See Note 12 for additional information on derivative instruments and hedging activities.

**NOTE 6:Earnings (Loss) Per Share**

Basic earnings (loss) per share is calculated as *Net income (loss) attributable to HF Sinclair stockholders*, adjusted for participating securities' share in earnings divided by the weighted-average number of shares of common stock outstanding. Diluted earnings (loss) per share reflects the dilutive effect of the incremental shares resulting from certain share-based awards. Anti-dilutive shares were immaterial for the periods presented.

The following is a reconciliation of the denominators of the basic and diluted per share computations for *Net income (loss) attributable to HF Sinclair stockholders*:

&nbsp;&nbsp;&nbsp;&nbsp;(1)Unvested restricted stock unit awards and unvested performance share units that settle in HF Sinclair common stock represent participating securities because they participate in nonforfeitable dividends or distributions with the common stockholders of HF Sinclair. Participating earnings represent the distributed and undistributed earnings of HF Sinclair attributable to the participating securities. Unvested restricted stock unit awards and performance share units do not participate in undistributed net losses as they are not contractually obligated to do so.

**NOTE 7:Stock-Based Compensation**

We have a principal share-based compensation plan, the HF Sinclair Corporation Amended and Restated 2020 Long Term Incentive Plan (the "2020 Plan"). The 2020 Plan provides for the grant of unrestricted and restricted stock, restricted stock units, other stock-based awards, stock options, performance awards, substitute awards, cash awards and stock appreciation rights. An aggregate of 6,368,930 of these awards may be issued pursuant to awards granted under the 2020 Plan. We also have a stock compensation deferral plan that allows non-employee directors to defer settlement of vested stock granted under our share-based compensation plan. Compensation expense for awards with pro-rata vesting is recognized ratably over the service periods. Share-based awards paid in cash upon vesting are accounted for as liability awards and recorded at fair value at the end of each reporting period with a mark-to-mark adjustment recognized in earnings. The liability awards held nominal balances as of March 31, 2026 and December 31, 2025.

The stock-based compensation expense was $7 million and $5 million for the three months ended March 31, 2026 and 2025, respectively.

A summary of restricted stock units and performance share units activity during the three months ended March 31, 2026 is presented below:

---

| | | |
|:---|:---|:---|
| | **Restricted Stock Units** | **Performance Share Units** |

&nbsp;&nbsp;&nbsp;&nbsp;(1)&nbsp;&nbsp;&nbsp;&nbsp;Due to rounding of reported numbers, some amounts may not calculate exactly.

For the three months ended March 31, 2026, the effective tax rate was higher than the statutory rate of 21.0%, which was 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 March 31, 2025, the effective tax rate was lower than the statutory rate of 21.0% primarily due to the relationship between pre-tax results, taxable permanent differences and discrete tax adjustments.

**NOTE 11:Debt**

***HF Sinclair Credit Agreement***

We have a $2.0 billion senior unsecured revolving credit facility maturing in April 2030 (the "HF Sinclair Credit Agreement") which contains an extension feature that allows us to extend the term of the commitment from time to time in increments of up to one year, subject to the terms and conditions set forth in the HF Sinclair Credit Agreement. The HF Sinclair Credit Agreement includes an accordion feature that allows us to increase such commitments to an aggregate principal amount of up to $2.75 billion. The HF Sinclair Credit Agreement may be used for revolving credit loans and letters of credit and is available to fund general corporate purposes.

At March 31, 2026, we were in compliance with all covenants and had no outstanding borrowings or letters of credit under the HF Sinclair Credit Agreement.

***Senior Notes***

Our unsecured senior notes and unsubordinated obligations rank equally with all future unsecured and unsubordinated indebtedness. We may, from time to time, seek to retire some or all of our outstanding debt agreements through cash purchases, and/or exchanges, open market purchases, privately negotiated transactions, tender offers or otherwise. Such transactions, if any, may be material and will depend on prevailing market conditions, our liquidity requirements and other factors.

***Financing Arrangements***

Certain of our wholly owned subsidiaries entered into financing arrangements whereby such subsidiaries sold a portion of their precious metals catalyst to a financial institution in exchange for cash and then financed the use of the precious metals catalyst for a term not to exceed one year. During the three months ended March 31, 2026, we received proceeds of $71 million, made principal payments of $25 million and realized non-cash settlements on obligations of $19 million related to such agreements.

We may, from time to time, issue letters of credit pursuant to uncommitted letters of credit facilities, which are unrelated to the HF Sinclair Credit Agreement. At March 31, 2026, we had letters of credit totaling a nominal amount under such credit facilities.

**NOTE 12:Derivative Instruments and Hedging Activities**

***Commodity Price Risk Management***

Our primary market risk is commodity price risk. We are exposed to market risks related to the volatility in the price of crude oil, other feedstocks and refined products and volatility in the price of natural gas used in our operations. We periodically enter into derivative contracts in the form of commodity price swaps, collar contracts, forward contracts and futures contracts to mitigate price exposure with respect to our inventory positions, natural gas purchases, sales prices of refined products and crude oil costs.

***Foreign Currency Risk Management***

We are exposed to market risk related to the volatility in foreign currency exchange rates. We periodically enter into derivative contracts in the form of foreign exchange forward contracts to mitigate the exposure associated with fluctuations in intercompany notes with our foreign subsidiaries that are not denominated in the U.S. dollar.

**HF SINCLAIR CORPORATION**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(Unaudited)**

***Economic Hedges***

We periodically enter into commodity and futures contracts to lock in prices for forecasted inventory purchases and sales, basis swaps to mitigate exposure to natural gas price volatility, and forward purchase and sale agreements to lock in basis spread differentials for forecasted crude oil and refined product transactions. Additionally, we periodically use collar contracts to mitigate exposure to natural gas price volatility. These contracts serve as economic hedges. We also have forward currency contracts to fix the rate of foreign currency. In addition, our precious metals financing arrangements discussed in Note 11 could require repayment under certain conditions based on the future pricing of precious metals, resulting in an embedded derivative. These contracts are measured at fair value with offsetting adjustments (gains/losses) recorded directly to earnings.

**NOTE 13:Stockholders**' **Equity**

In May 2024, our Board of Directors approved a $1.0 billion share repurchase program (the "2024 Share Repurchase Program"), which replaced all existing share repurchase programs. The 2024 Share Repurchase Program authorizes us to repurchase common stock in the open market or through privately negotiated transactions. Privately negotiated repurchases from REH Advisors Inc. ("REH") are also authorized under the 2024 Share Repurchase Program, subject to REH's interest in selling its shares and other limitations. The timing and amount of share repurchases, including those from REH, will depend on market conditions and corporate, tax, regulatory and other relevant considerations. In addition, we are authorized by our Board of Directors to repurchase shares in an amount sufficient to offset shares issued under our compensation programs. The 2024 Share Repurchase Program may be discontinued at any time by our Board of Directors.

As of March 31, 2026, we had remaining authorization to repurchase up to $383 million under the 2024 Share Repurchase Program.

The following table presents the total open market purchases of shares under our share repurchase program for the three months ended March 31, 2026 and 2025:

During the three months ended March 31, 2026 and 2025, we withheld 205 and 1,221 shares, respectively, of our common stock from certain employees. These nominal withholdings were made under the terms of restricted stock unit and performance share unit agreements upon vesting, at which time we concurrently made cash payments to fund payroll and income taxes on behalf of officers and employees.

On May 1, 2026, our Board of Directors announced that it 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.

**NOTE 15:Commitments and Contingencies**

We are a party to various litigation and legal proceedings in the ordinary course of business that we believe, based on the advice of counsel, will not have, either individually or in the aggregate, a material adverse effect on our financial condition, results of operations or cash flows.

In August 2025, the EPA granted and denied, in whole or in part, small refinery exemption petitions for our Woods Cross, Cheyenne, Casper and Parco refineries for various compliance years from 2019 to 2024. In October 2025, certain of our subsidiaries filed lawsuits in the U.S. Court of Appeals for the District of Columbia Circuit (the "DC Circuit") to overturn the EPA's August 2025 denials and other actions (the "August 2025 cases"). In November 2025, the EPA granted in whole small refinery exemption petitions for our refinery in Tulsa, Oklahoma (the "Tulsa East Refinery") for compliance years 2023 and 2024 and partially granted exemptions to several other refining companies. In December 2025, the Renewable Fuels Association filed a lawsuit challenging those exemptions, and the proceedings were subsequently consolidated with the August 2025 cases (the "Consolidated Cases"). In January 2026, certain of our subsidiaries intervened in the Consolidated Cases to defend the EPA's grant of our Tulsa East Refinery exemptions. The DC Circuit has entered a briefing schedule in the Consolidated Cases, with our opening brief due on July 10, 2026.

Separately, in March 2026, the DC Circuit heard oral arguments in two severed cases arising from the EPA's August 2025 decisions, including one addressing the denial of our Parco refinery's exemption petition for the 2024 compliance year. On April 7, 2026, the DC Circuit issued a unanimous decision in our favor, holding that the EPA erred in deeming the Parco refinery ineligible for an exemption from its Renewable Fuel Standard obligations for the 2024 compliance year. The DC Circuit vacated the EPA's denial and remanded the matter to the agency for a new decision on Parco refinery's small refinery exemption petition.

These matters remain pending, and we are unable to estimate the impact at this time.

**NOTE 16:Segment Information**

Our operations are organized into five reportable segments: Refining, Renewables, Marketing, Lubricants & Specialties and Midstream. Our operations that are not included in one of these five reportable segments are included in Corporate and Other. Intersegment transactions are eliminated in our consolidated financial statements and are included in Eliminations. Corporate and Other and Eliminations are aggregated and presented under the Corporate, Other and Eliminations column.

The Refining segment represents the operations of our El Dorado, Tulsa, Navajo, Woods Cross, Puget Sound, Parco and Casper refineries and HF Sinclair Asphalt Company LLC ("Asphalt"). Refining activities involve the purchase and refining of crude oil and wholesale marketing of refined products, such as gasoline, diesel fuel and jet fuel. These petroleum products are primarily marketed in the Mid-Continent, Southwest, Rocky Mountains and Pacific Northwest geographic regions of the United States. Asphalt operates various asphalt terminals in Arizona, New Mexico and Oklahoma.

The Renewables segment represents the operations of our Cheyenne RDU, Artesia RDU, Sinclair RDU and the pre-treatment unit at our Artesia, New Mexico facility.

**(Unaudited)**

The Marketing segment represents branded fuel sales to Sinclair branded sites in the United States and licensing fees for the use of the Sinclair brand at additional locations throughout the country. Branded fuel is also sold to non-Sinclair branded sites and includes revenues from other marketing activities. Our branded sites are located in several states across the United States with the highest concentration of sites in our West and Mid-Continent regions. In February 2026, we formed the joint venture Green Trail Fuels, LLC in which we hold a 50% non-operating economic interest. The joint venture includes various retail sites across Colorado and New Mexico and is supplied fuel by our proximate regional refineries.

The Lubricants & Specialties segment includes Petro-Canada Lubricants' production operations, located in Mississauga, Ontario, which produces lubricant products such as base oils, white oils, specialty products and finished lubricants, and the operations of our Petro-Canada Lubricants business that includes the marketing of products to both retail and wholesale outlets through a global sales network with locations in Canada, the United States and Europe. Additionally, the Lubricants & Specialties segment includes specialty lubricant products produced at our Tulsa facilities that are marketed throughout North America and are distributed in Central and South America and includes the operations of Red Giant Oil, one of the leading suppliers of locomotive engine oil in North America. Also, the Lubricants & Specialties segment includes Sonneborn, a producer of specialty hydrocarbon chemicals such as white oils, petrolatums and waxes with manufacturing facilities in the United States and Europe.

The Midstream segment includes all of the operations of HEP, which owns and operates logistics and refinery assets consisting of petroleum product and crude oil pipelines, terminals, tankage and loading rack facilities in the Mid-Continent, Southwest and Rocky Mountains geographic regions of the United States. The Midstream segment also includes 50% ownership interests in each of Osage Pipeline Company, LLC, the owner of a pipeline running from Cushing, Oklahoma to El Dorado, Kansas, and Cushing Connect Pipeline & Terminal LLC, the owner of a pipeline running from Cushing, Oklahoma to Tulsa, Oklahoma, a 26.08% ownership interest in Saddle Butte Pipeline III, LLC, the owner of a pipeline running from the Powder River Basin to Casper, Wyoming, and a 49.995% ownership interest in Pioneer Investments Corp., the owner of a pipeline running from Sinclair, Wyoming to the North Salt Lake City, Utah terminal. Revenues and other income from the Midstream segment are earned through transactions with unaffiliated parties for pipeline transportation, rental and terminalling operations, and revenues relating to pipeline transportation, terminalling operations and tankage facilities provided for our refining operations.

Our chief operating decision maker ("CODM"), who is also our Chief Executive Officer, evaluates the performance of our segments using segment *Income (loss) from operations*. The CODM uses segment *Income (loss) from operations* to allocate resources and assess performance of the Company's segments. Amounts included in *Income (loss) before income taxes* in our consolidated statements of operations and excluded from our performance measure, *Income (loss) from operations*, include *Other income (expense), net. Other income (expense), net* includes *Earnings of equity method investments*, *Interest income*, *Interest expense* and other items believed to be non-operating and/or non-recurring in nature. Assets by segment are not a measure used to assess our performance by the CODM and thus are not reported in our disclosures. Intersegment sales are generally derived from transactions made at prevailing market rates.

The accounting policies for our segments are the same as those described in the summary of significant accounting policies in our Annual Report on Form 10-K for the year ended December 31, 2025.

The following is a summary of the financial information of our reportable segments reconciled to the amounts reported in the consolidated financial statements.

**<u>Item 2.</u><u>Management's Discussion and Analysis of Financial Condition and Results of Operations</u>**

This Item 2 contains "forward-looking" statements. See "Forward-Looking Statements" at the beginning of Part I of this Quarterly Report on Form 10-Q. In this document, the words "we," "our," "ours" and "us" refer only to HF Sinclair and its consolidated subsidiaries or to HF Sinclair or an individual subsidiary and not to any other person, with certain exceptions.

We use certain non-GAAP financial measures in our Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A"). For a description of each of the non-GAAP measures used in this MD&A, please refer to the discussion under "Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles" following Item 2 of Part I of this Quarterly Report on Form 10-Q. This Item 2 should be read in conjunction with our consolidated financial statements and the notes thereto included in this interim report. In addition, this Item 2 should be read in conjunction with our audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2025.

**OVERVIEW**

We are an independent energy company that produces and markets high-value light products such as gasoline, diesel fuel, jet fuel, renewable diesel and lubricants and specialty products. We own and operate refineries located in Kansas, Oklahoma, New Mexico, Wyoming, Washington and Utah. We provide petroleum product and crude oil transportation, terminalling, storage and throughput services to our refineries and the petroleum industry. We market our refined products principally in the Southwest United States, the Rocky Mountains extending into the Pacific Northwest and in other neighboring Plains states, and we supply high-quality fuels to more than 1,750 branded stations and license the use of the Sinclair brand to more than 350 additional locations throughout the country. We produce renewable diesel at two of our facilities in Wyoming and one facility in New Mexico. In addition, our subsidiaries produce and market base oils and other specialized lubricants in the United States, Canada and the Netherlands, and export products to more than 80 countries.

**Market Developments**

For the three months ended March 31, 2026, *Net income attributable to HF Sinclair stockholders* was $648 million, compared to a *Net loss attributable to HF Sinclair stockholders* of $4 million in the three months ended March 31, 2025. Adjusted refinery gross margin per barrel sold increased $0.83, or 9%, from $9.12 for the three months ended March 31, 2025, to $9.95 for the three months ended March 31, 2026.

In the Refining segment, we saw stronger refining margins in the West region in the back half of the quarter, which were partially offset by weaker refining margins in the Mid-Continent region throughout the quarter. Additionally, our results were impacted by planned turnarounds at our Puget Sound and Woods Cross refineries. For the second quarter of 2026, we expect to run between 600,000-630,000 barrels per day of crude oil, which reflects the completion of the turnarounds at our Puget Sound and Woods Cross refineries, planned maintenance at our Parco and Navajo refineries and unplanned maintenance at our El Dorado refinery.

In the Renewables segment, higher margins in the quarter were a result of the narrowing of the BOHO spread, higher RINs prices and higher Producer's Tax Credit ("PTC") benefits. PTCs recognized in the first quarter of 2026 included prior year 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. For the second quarter of 2026, we expect continued strength in RINs and LCFS prices.

In the Marketing segment, we continued to realize strong value from our Sinclair branded sites during the first quarter of 2026, as the marketing business provided a consistent sales channel with margin uplift for our produced fuels. We expect to grow the number of branded sites by approximately 10% annually. In February 2026, we formed Green Trail Fuels, LLC, a new joint venture in which we hold a 50% non-operating economic interest. The new joint venture includes various retail sites across Colorado and New Mexico.

In the Lubricants & Specialties segment, our results (excluding first-in, first out ("FIFO") impacts) were impacted by the dislocation between rising feedstock costs and product sales price increases during the three months ended March 31, 2026. Results for the quarter included contributions from our January 2026 acquisition of Industrial Oils Unlimited, LLC, which expanded our specialty product portfolio and is expected to support future growth opportunities.

------

<u>[**Table of Contents**](#i8a7e7204dda24d31bd2f2d3b6dddb540_7)</u>

In the Midstream segment, our results continued to benefit from higher third-party pipeline revenues during the three months ended March 31, 2026, but were marginally impacted by a fuel-contamination incident at one of our product terminals in Colorado in the first quarter of 2026.

We continue to review and adjust our operational plans to evolving market conditions. The extent to which our future results are affected by volatile regional and global economic conditions, including ongoing tariff and trade negotiations and global hostilities, such as the ongoing military conflict in the Middle East, will depend on various factors and consequences beyond our control.

On May 1, 2026, our Board of Directors announced that it 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.

**Renewable Fuel Standard Regulations**

Pursuant to the 2007 Energy Independence and Security Act, the EPA promulgated the Renewable Fuel Standard ("RFS") regulations, which increased the volume of renewable fuels mandated to be blended into the nation's fuel supply. The regulations, in part, require refiners to satisfy annual renewable volume obligations calculated as a percentage of their petroleum fuel shipments or imports, which may be met through physical blending of renewable fuels or by purchasing and retiring RINs. Compliance with RFS regulations significantly increased our *Cost of materials and other*, with RINs costs totaling $358 million for the three months ended March 31, 2026. During the three months ended March 31, 2026, we recognized $21 million in *Sales and other revenues* related to the small refinery RINs waivers granted by the EPA in the fourth quarter of 2025. At March 31, 2026, our open RINs credit obligations were $306 million.

A more detailed discussion of our financial and operating results for the three months ended March 31, 2026 and 2025 is presented in the following sections.

&nbsp;&nbsp;&nbsp;&nbsp;(1)Earnings before interest, taxes, depreciation and amortization, which we refer to as "EBITDA," is calculated as *Net income (loss) 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 16 "Segment Information" in the Notes to 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 March 31, 2026 Compared to Three Months Ended March 31, 2025**

***Summary***

*Net income attributable to HF Sinclair stockholders* for the three months ended March 31, 2026, was $648 million ($3.56 per basic and diluted share), a $652 million increase compared to the *Net loss attributable to HF Sinclair stockholders* of $4 million ($(0.02) per basic and diluted share) for the three months ended March 31, 2025. The increase in *Net income attributable to HF Sinclair stockholders* was primarily driven by the *Lower of cost or market inventory valuation adjustments* in addition to improved adjusted refinery gross margins and adjusted renewables gross margins during the three months ended March 31, 2026. *Lower of cost or market inventory valuation adjustments* related to our Refining and Renewables segment inventories increased pre-tax earnings by $672 million for the three months ended March 31, 2026 and increased pre-tax earnings by $117 million for the three months ended March 31, 2025. Adjusted renewables gross margins reflected narrower BOHO spreads and significant PTC benefits during the three months ended March 31, 2026, while no comparable benefit was recognized during the three months ended March 31, 2025. These favorable impacts were partially offset by a $188 million increase in *Income tax expense*.

------

<u>[**Table of Contents**](#i8a7e7204dda24d31bd2f2d3b6dddb540_7)</u>

***Sales and Other Revenues***

*Sales and other revenues* increased $753 million, or 12%, from $6,370 million for the three months ended March 31, 2025, to $7,123 million for the three months ended March 31, 2026, principally due to higher average refined product sales prices and higher sales volumes of refined products. *Sales and other revenues* included $208 million, $792 million, $653 million and $31 million in unaffiliated revenues related to our Renewables, Marketing, Lubricants & Specialties and Midstream segments, respectively, for the three months ended March 31, 2026. *Sales and other revenues* included $94 million, $686 million, $638 million and $29 million in unaffiliated revenues related to our Renewables, Marketing, Lubricants & Specialties and Midstream segments, respectively, for the three months ended March 31, 2025.

***Cost of Materials and Other***

*Cost of materials and other*, exclusive of *Lower of cost or market inventory valuation adjustments*, increased $504 million, or 9%, from $5,476 million for the three months ended March 31, 2025, to $5,980 million for the three months ended March 31, 2026, principally due to higher crude oil and feedstock costs and higher sales volumes of refined products. Within our Lubricants & Specialties segment, the FIFO impact was a benefit of $53 million and $8 million for the three months ended March 31, 2026 and 2025, respectively.

During the first quarter of 2026, we recognized a lower of cost or market inventory valuation adjustment benefit of $672 million compared to a benefit of $117 million during the first quarter of 2025.

***Adjusted Refinery Gross Margin***

Adjusted refinery gross margin per barrel sold increased $0.83, or 9%, from $9.12 for the three months ended March 31, 2025, to $9.95 for the three months ended March 31, 2026. The year-over-year increase was primarily driven by higher refinery margins in the West region.

Adjusted refinery gross margin per barrel excludes the cash effects of *Lower of cost or market inventory valuation adjustments* 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 $28 million, or 5%, from $596 million for the three months ended March 31, 2025, to $624 million for the three months ended March 31, 2026, primarily due to a fuel-contamination incident at one of our product terminals in Colorado during the three months ended March 31, 2026 and higher contractor and other miscellaneous costs.

***Selling, General and Administrative Expenses***

*Selling, general and administrative expenses* increased $11 million, or 11%, from $104 million for the three months ended March 31, 2025, to $115 million for the three months ended March 31, 2026, primarily due to an increase in professional services and other miscellaneous costs.

***Earnings of Equity Method Investments***

Earnings of equity method investments decreased $3 million, or 27% from $11 million for the three months ended March 31, 2025, to $8 million for the three months ended March 31, 2026, primarily due to the divestiture of our investment in Cheyenne Pipeline, LLC in the three months ended March 31, 2025.

***Depreciation and Amortization Expenses***

*Depreciation and amortization* remained relatively consistent and was $229 million and $225 million for the three months ended March 31, 2026 and 2025, respectively.

***Interest Income***

*Interest income* remained relatively flat and was $10 million and $9 million for the three months ended March 31, 2026 and 2025, respectively.

***Interest Expense***

*Interest expense* was $41 million for the three months ended March 31, 2026, compared to $49 million for the three months ended March 31, 2025. This decrease was primarily due to unrealized losses on precious metals financing arrangements during the period.

<u>[**Table of Contents**](#i8a7e7204dda24d31bd2f2d3b6dddb540_7)</u>

***Other Income (Expense), net***

*Other income (expense), net* was $15 million for three months ended March 31, 2026 compared to $(53) million for the three months ended March 31, 2025. During the three months ended March 31, 2026, we recognized a $14 million gain on settlement of precious metals. During the three months ended March 31, 2025, we assigned our 50% ownership interest in Cheyenne Pipeline, LLC to our joint venture partner in exchange for the cancellation of certain future commitments, resulting in a loss on sale of equity method investment of $40 million. Additionally, during the three months ended March 31, 2025, we recognized an early extinguishment loss on debt of $15 million, inclusive of unamortized discount and debt issuance costs, as a result of the tendering and redemption of certain debt.

***Income Taxes***

For the three months ended March 31, 2026, *Income tax expense* of $189 million was recorded on pre-tax income of $839 million, compared to *Income tax expense* of $1 million on pre-tax loss of $1 million for the three months ended March 31, 2025. The increase was primarily due to higher pre-tax earnings year-over-year.

**LIQUIDITY AND CAPITAL RESOURCES**

We have a disciplined capital allocation strategy focused on preserving financial flexibility, enabling us to execute our capital priorities and generate long-term value for our stockholders. Consistent with that strategy, we seek to self-fund development projects and make strategic investments focused on profitable growth, while reducing our debt and returning cash to stockholders through dividends and share repurchases.

***HF Sinclair Credit Agreement***

We have a $2.0 billion senior unsecured revolving credit facility maturing in April 2030 (the "HF Sinclair Credit Agreement") which contains an extension feature that allows us to extend the term of the commitment from time to time in increments of up to one year subject to the terms and conditions set forth in the HF Sinclair Credit Agreement. The HF Sinclair Credit Agreement includes an accordion feature that allows us to increase such commitments to an aggregate principal amount of up to $2.75 billion. The HF Sinclair Credit Agreement may be used for revolving credit loans and letters of credit and is available to fund general corporate purposes.

At March 31, 2026, we were in compliance with all covenants and had no outstanding borrowings or letters of credit under the HF Sinclair Credit Agreement.

***Senior Notes***

Our unsecured senior notes and unsubordinated obligations rank equally with all future unsecured and unsubordinated indebtedness. We may, from time to time, seek to retire some or all of our outstanding debt agreements through cash purchases, and/or exchanges, open market purchases, privately negotiated transactions, tender offers or otherwise. Such transactions, if any, may be material and will depend on prevailing market conditions, our liquidity requirements and other factors.

***Financing Arrangements***

Certain of our wholly owned subsidiaries entered into financing arrangements whereby such subsidiaries sold a portion of their precious metals catalyst to a financial institution in exchange for cash and then financed the use of the precious metals catalyst for a term not to exceed one year. During the three months ended March 31, 2026, we received proceeds of $71 million, made principal payments of $25 million and realized non-cash settlements on obligations of $19 million related to such agreements. Upon maturity of the financing arrangements, we must either extend the maturity or satisfy the obligation at fair market value, which is considered an embedded derivative.

We may, from time to time, issue letters of credit pursuant to uncommitted letters of credit facilities, which are unrelated to the HF Sinclair Credit Agreement. At March 31, 2026, we had letters of credit totaling a nominal amount under such credit facilities.

See Note 11 "Debt" in the Notes to Consolidated Financial Statements for additional information on our debt instruments.

***Liquidity***

We believe our current *Cash and cash equivalents*, along with future internally generated cash flow and funds available under our credit facilities, will provide sufficient resources to fund currently planned capital projects and our current liquidity needs. We expect that, to the extent necessary, we can raise additional funds through equity or debt financings in the public and private capital markets. Further, we may seek to retire some or all of our outstanding debt agreements through cash purchases, and/or exchanges, open market purchases, privately negotiated transactions, tender offers or otherwise. Such transactions, if any, may be material and depend on prevailing market conditions, our liquidity requirements and other factors. In addition, components of our long-term growth strategy include the optimization of existing units at our facilities, expansion of our Midstream footprint and selective acquisition of complementary assets for our operations intended to capture synergies and increase earnings and cash flow. We also expect to use cash for payment of cash dividends, which are at the discretion of our Board of Directors, and for the repurchase of common stock under the 2024 Share Repurchase Program.

Our liquidity was approximately $3.1 billion at March 31, 2026, consisting of *Cash and cash equivalents* of $1.1 billion and $2.0 billion available under the HF Sinclair Credit Agreement.

We consider all highly liquid instruments with a maturity of three months or less at the time of purchase to be cash equivalents. These primarily consist of investments in liquid, highly rated instruments issued by financial institutions, government and corporate entities with strong credit standings and money market funds. Cash equivalents are stated at cost, which approximates market value.

In May 2024, our Board of Directors approved a $1.0 billion share repurchase program (the "2024 Share Repurchase Program"), which replaced all existing share repurchase programs. The 2024 Share Repurchase Program authorizes us to repurchase common stock in the open market or through privately negotiated transactions. Privately negotiated repurchases from REH Advisors Inc. ("REH") are also authorized under the 2024 Share Repurchase Program, subject to REH's interest in selling its shares and other limitations. The timing and amount of share repurchases, including those from REH, will depend on market conditions and corporate, tax, regulatory and other relevant considerations. In addition, we are authorized by our Board of Directors to repurchase shares in an amount sufficient to offset shares issued under our compensation programs. The 2024 Share Repurchase Program may be discontinued at any time by our Board of Directors.

During the three months ended March 31, 2026, we made open market purchases of 1,514,810 shares for $76 million under our 2024 Share Repurchase Program. As of March 31, 2026, we had remaining authorization to repurchase up to $383 million under the 2024 Share Repurchase Program.

**Cash Flows – Operating Activities**

***Three Months Ended March 31, 2026 Compared to Three Months Ended March 31, 2025***

*Net cash flows provided by operating activities* were $457 million for the three months ended March 31, 2026, compared to *Net cash flows used for operating activities of* $89 million for the three months ended March 31, 2025, an increase of $546 million, primarily driven by changes in working capital. Changes in working capital increased operating cash flows by $316 million for the three months ended March 31, 2026, and decreased operating cash flows by $144 million for the three months ended March 31, 2025.

**Cash Flows – Investing Activities and Planned Capital Expenditures**

***Three Months Ended March 31, 2026 Compared to Three Months Ended March 31, 2025***

For the three months ended March 31, 2026, our *Net cash flows used for investing activities* were $161 million, which was inclusive of our acquisition of Industrial Oils Unlimited, LLC and our investment in Green Trail Fuels, LLC. Cash expenditures for *Properties, plants and equipment* for the three months ended March 31, 2026 were $102 million.

For the three months ended March 31, 2025, our *Net cash flows used for investing activities* were $85 million. Cash expenditures for *Properties, plants and equipment* for the three months ended March 31, 2025 were $86 million.

**Cash Flows – Financing Activities**

***Three Months Ended March 31, 2026 Compared to Three Months Ended March 31, 2025***

For the three months ended March 31, 2026, our *Net cash flows used for financing activities* were $125 million. During the three months ended March 31, 2026, we paid $91 million in *Dividends*, we repurchased $76 million of our *Common stock* and we received net proceeds of $46 million from financing arrangements.

For the three months ended March 31, 2025, our *Net cash flows used for financing activities* were $80 million. During the three months ended March 31, 2025, we paid $95 million in *Dividends,* repaid $350 million under the now-terminated revolving credit facility of our subsidiary, Holly Energy Partners, L.P., and had net proceeds from the issuance and redemption of certain senior notes of $387 million.

**Contractual Obligations and Commitments**

As of March 31, 2026, our contractual obligations included debt obligations, interest payments related to debt obligations, financing arrangements, supply agreements, transportation and storage agreements, operating and finance leases, and other long-term obligations and commitments. In the ordinary course of business, we had debt-related activities during the three months ended March 31, 2026, as described in Note 11 "Debt" of the Consolidated Financial Statements.

There were no material changes outside the ordinary course of business with respect to our contractual obligations during the three months ended March 31, 2026.

**CRITICAL ACCOUNTING POLICIES AND ESTIMATES**

The preparation of these financial statements requires us to make estimates and judgments that affect the amounts reported in our consolidated financial statements and accompanying notes. Actual results may differ from those estimates. There have been no changes to the critical accounting policies or estimates disclosed in "Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates" in our Annual Report on Form 10-K for the year ended December 31, 2025.

**RISK MANAGEMENT**

We use certain strategies to reduce some commodity price and operational risks. We do not attempt to eliminate all market risk exposures when we believe that the exposure relating to such risk would not be significant to our future earnings, financial position, capital resources or liquidity or that the cost of eliminating the exposure would outweigh the benefit.

------

<u>[**Table of Contents**](#i8a7e7204dda24d31bd2f2d3b6dddb540_7)</u>

***Commodity Price Risk Management***

Our primary market risk is commodity price risk. We are exposed to market risks related to the volatility in the price of crude oil and refined products and volatility in the price of natural gas used in our refining operations. We periodically enter into derivative contracts in the form of commodity price swaps, collar contracts, forward contracts and futures contracts to mitigate price exposure with respect to our inventory positions, natural gas purchases, sales prices of refined products and crude oil costs.

***Foreign Currency Risk Management***

We are exposed to market risk related to the volatility in foreign currency exchange rates. We periodically enter into derivative contracts in the form of foreign exchange forward contracts to mitigate the exposure associated with fluctuations on intercompany notes with our foreign subsidiaries that are not denominated in the U.S. dollar.

As of March 31, 2026, we have the following notional amounts related to all outstanding derivative instruments used to mitigate commodity price and foreign currency risk:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | | **Notional Contract Volumes <br>by Year of Maturity** | **Notional Contract Volumes <br>by Year of Maturity** | |
|<br>**Contract Description** |<br>**Total Outstanding Notional** | **2026** | **2027** |<br>**Unit of Measure** |
| NYMEX futures (WTI) - short | 1480000 | 1480000 |  | Barrels |
| Commodity forward contracts - long | 2144776 | 2144776 |  | Barrels |
| Commodity forward contracts - short | 1882000 | 1882000 |  | Barrels |
| Foreign currency forward contracts | 522000000 | 381294900 | 140705100 | Canadian dollar |
| Forward platinum contracts <sup>(1)</sup> | 62371 | 27445 | 34926 | Troy ounces |

&nbsp;&nbsp;&nbsp;&nbsp;(1)Represents an embedded derivative within our precious metals financing arrangements, which may be refinanced or require repayment under certain conditions. See Note 11 "Debt" in the Notes to Consolidated Financial Statements for additional information on these financing arrangements.

Counterparty financial information is reviewed to monitor financial stability and assess the ongoing ability to honor commitments under derivative contracts. We have not experienced, nor do we expect to experience, any difficulty in counterparties honoring their commitments.

The following sensitivity analysis provides the hypothetical effects of market price fluctuations related to outstanding derivative instruments:

---

| | | |
|:---|:---|:---|
| | **March 31,** | **March 31,** |
|<br>**Derivative Fair Value Gain (Loss)** | **2026** | **2025** |
|  | (In millions) | (In millions) |
| 10% increase in underlying commodity prices | $(14) | $(17) |
| 10% decrease in underlying commodity prices | $14 | $17 |

---

***Interest Rate Risk Management***

The market risk inherent in our fixed-rate debt is the potential change arising from increases or decreases in interest rates, as discussed below.

For the fixed rate HF Sinclair, HollyFrontier and HEP Senior Notes (each as demarcated in Note 11 "Debt" in the Notes to Consolidated Financial Statements), changes in interest rates will generally affect the fair value of the debt, but not earnings or cash flows.

The outstanding principal, estimated fair value and estimated change in fair value (assuming a hypothetical 10% change in the yield-to-maturity rates) for this debt as of March 31, 2026, are presented below:

---

| | | | |
|:---|:---|:---|:---|
| | **Outstanding<br>Principal** | **Estimated<br>Fair Value** | **Estimated Change in Fair Value** |
| | (In millions) | (In millions) | (In millions) |
| HF Sinclair, HollyFrontier and HEP Senior Notes | $2800 | $2831 | $73 |

---

------

<u>[**Table of Contents**](#i8a7e7204dda24d31bd2f2d3b6dddb540_7)</u>

For the variable rate under the HF Sinclair Credit Agreement, changes in interest rates would affect cash flows, but not the fair value. At March 31, 2026, there were no amounts outstanding under the HF Sinclair Credit Agreement. A hypothetical 10% change in interest rates applicable to the HF Sinclair Credit Agreement would not materially affect cash flows.

***Operational Interruption Risk Management***

Our operations are subject to catastrophic losses, operational hazards and unforeseen interruptions, including but not limited to fire, explosion, releases or spills, cyberattacks, weather-related perils, vandalism, power failures, mechanical failures and other events beyond our control. We maintain various insurance coverages, including general liability, property damage, business interruption and cyber insurance, subject to certain deductibles and insurance policy terms and conditions. We are not fully insured against certain risks because such risks are not fully insurable, coverage is unavailable, or premium costs, in our judgment, do not justify such expenditures.

We have a risk management oversight committee consisting of members from our senior management. This committee oversees our risk enterprise program, monitors our risk environment and provides direction for activities to mitigate identified risks that may adversely affect the achievement of our goals.

**Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles**

***Reconciliations of earnings before interest, taxes, depreciation and amortization ("EBITDA") to amounts reported under generally accepted accounting principles 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* 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 (loss)* 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 our operating performance. EBITDA is also used by our management for internal analysis and as a basis for financial covenants.

Below is our calculation of EBITDA:

***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 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.

**<u>Item 4.</u><u>Controls and Procedures</u>**

**Evaluation of Disclosure Controls and Procedures**

The Company's management, with the participation of the principal executive officer and principal financial officer of the Company, has evaluated the effectiveness of the design and operation of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of March 31, 2026, the end of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, the Company's principal executive officer and principal financial officer have concluded that, as of March 31, 2026, the Company's disclosure controls and procedures are effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the required time periods and are designed to ensure that information required to be disclosed in its reports is accumulated and communicated to the Company's management, including the principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

**Changes in Internal Control Over Financial Reporting**

There were no changes in the Company's internal control over financial reporting that occurred during the quarter ended March 31, 2026, that have materially affected, or are reasonably likely to materially affect, internal controls over financial reporting.

**PART II. OTHER INFORMATION**

**<u>Item 1.</u><u>Legal Proceedings</u>**

**Commitment and Contingency Reserves**

In the ordinary course of business, we may become party to legal, regulatory or administrative proceedings or governmental investigations, including environmental and other matters. Damages or penalties may be sought from us in some matters and certain matters may require years to resolve. While the outcome and impact of these proceedings and investigations on us cannot be predicted with certainty, based on the advice of counsel and information currently available to us, management believes that the resolution of these proceedings and investigations through settlement or adverse judgment will not have a material adverse effect, either individually or in the aggregate, on our financial condition, results of operations or cash flows.

The environmental proceedings are reported to comply with SEC regulations which require us to disclose proceedings arising under provisions regulating the discharge of materials into the environment or protecting the environment when a governmental authority is party to the proceedings and such proceedings involve potential monetary sanctions that we reasonably believe could exceed $1 million or more.

Except as described below, there have been no material changes to the legal matters previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2025.

**Environmental Matters**

**Renewable Fuel Standard**

In August 2025, the EPA granted and denied, in whole or in part, small refinery exemption petitions for our Woods Cross, Cheyenne, Casper and Parco refineries for various compliance years from 2019 to 2024. In October 2025, certain of our subsidiaries filed lawsuits in the U.S. Court of Appeals for the District of Columbia Circuit (the "DC Circuit") to overturn the EPA's August 2025 denials and other actions (the "August 2025 cases"). In November 2025, the EPA granted in whole small refinery exemption petitions for our refinery in Tulsa, Oklahoma (the "Tulsa East Refinery") for compliance years 2023 and 2024 and partially granted exemptions to several other refining companies. In December 2025, the Renewable Fuels Association filed a lawsuit challenging those exemptions, and the proceedings were subsequently consolidated with the August 2025 cases (the "Consolidated Cases"). In January 2026, certain of our subsidiaries intervened in the Consolidated Cases to defend the EPA's grant of our Tulsa East Refinery exemptions. The DC Circuit has entered a briefing schedule in the Consolidated Cases, with our opening brief due on July 10, 2026.

Separately, in March 2026, the DC Circuit heard oral arguments in two severed cases arising from the EPA's August 2025 decisions, including one addressing the denial of our Parco refinery's exemption petition for the 2024 compliance year. On April 7, 2026, the DC Circuit issued a unanimous decision in our favor, holding that the EPA erred in deeming the Parco refinery ineligible for an exemption from its Renewable Fuel Standard obligations for the 2024 compliance year. The DC Circuit vacated the EPA's denial and remanded the matter to the agency for a new decision on Parco refinery's small refinery exemption petition.

These matters remain pending, and we are unable to estimate the impact at this time.

**<u>Item 1A.</u><u>Risk Factors</u>**

There have been no material changes in our risk factors as previously disclosed in Part I, "Item 1A. Risk Factors" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025. You should carefully consider the risk factors discussed in our 2025 Form 10-K, which could materially affect our business, financial condition or future results. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.

In May 2024, our Board of Directors approved a $1.0 billion share repurchase program (the "2024 Share Repurchase Program"), which replaced all existing share repurchase programs. The 2024 Share Repurchase Program authorizes us to repurchase common stock in the open market or through privately negotiated transactions. Privately negotiated repurchases from REH Advisors Inc. ("REH") are also authorized under the 2024 Share Repurchase Program, subject to REH's interest in selling its shares and other limitations. The timing and amount of share repurchases, including those from REH, will depend on market conditions and corporate, tax, regulatory and other relevant considerations. In addition, we are authorized by our Board of Directors to repurchase shares in an amount sufficient to offset shares issued under our compensation programs. The 2024 Share Repurchase Program may be discontinued at any time by our Board of Directors.

As of March 31, 2026, we had remaining authorization to repurchase up to $383 million under the 2024 Share Repurchase Program.
