Financial Data

Balance Sheet Data

Other Financial Data

(1)Earnings before interest, taxes, depreciation and amortization, which we refer to as “EBITDA,” is calculated as net income attributable to HF Sinclair stockholders plus (i) interest expense, net of interest income, (ii) income tax provision, 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 operating income 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 widely used financial indicator 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 3 of Part I of this Quarterly Report on Form 10-Q.

Results of Operations – Three Months Ended June 30, 2024 Compared to Three Months Ended June 30, 2023

Summary

Net income attributable to HF Sinclair stockholders for the three months ended June 30, 2024, was $151.8 million ($0.79 per basic and diluted share), a $355.9 million decrease compared to net income of $507.7 million ($2.62 per basic and diluted share) for the three months ended June 30, 2023. The decrease in net income was principally driven by lower adjusted refinery gross margins in both the West and Mid-Continent regions, partially offset by higher refined product sales volumes. Lower of cost or market inventory reserve adjustments related to our refining and renewables inventories increased pre-tax earnings by $3.1 million for the three months ended June 30, 2024, and decreased pre-tax earnings by $7.9 million for the three months ended June 30, 2023. Adjusted refinery gross margins for the three months ended June 30, 2024, decreased to $11.33 per produced barrel sold as compared to $21.99 for the three months ended June 30, 2023.

Sales and Other Revenues

Sales and other revenues increased 0.2% from $7,833.6 million for the three months ended June 30, 2023, to $7,845.8 million for the three months ended June 30, 2024, principally due to higher refined product sales volumes, partially offset by decreased refined product sales prices and lower excess crude oil sales volumes as a result of fewer planned maintenance activities in 2024. Sales and other revenues included $942.4 million, $726.0 million, $27.1 million and $180.2 million in unaffiliated revenues related to our Marketing, Lubricants & Specialties, Midstream and Renewables segments, respectively, for the three months ended June 30, 2024. Sales and other revenues included $1,040.9 million, $686.1 million, $29.8 million and $175.1 million in unaffiliated revenues related to our Marketing, Lubricants & Specialties, Midstream and Renewables segments, respectively, for the three months ended June 30, 2023.

Cost of Materials and Other

Cost of materials and other, exclusive of lower of cost or market inventory valuation adjustments, increased 8% from $6,273.6 million for the three months ended June 30, 2023, to $6,750.5 million for the three months ended June 30, 2024, principally due to higher refined product sales volumes and higher crude oil costs, partially offset by lower excess crude oil sales volumes as a result of fewer planned maintenance activities in 2024. Within our Lubricants & Specialties segment, the first in, first out (“FIFO”) impact was a charge of $14.4 million for the three months ended June 30, 2024, compared to a benefit of $0.5 million for thethree months ended June 30, 2023.

During the second quarter of 2023, we recognized a lower of cost or market inventory valuation adjustment charge related to our Refining segment inventories of $26.8 million. Additionally, during the second quarter of 2024 and 2023, we recognized a lower of cost or market inventory valuation adjustment benefit related to our Renewables segment inventories of $3.1 million and $34.7 million, respectively.

Adjusted Refinery Gross Margins

Adjusted refinery gross margin per produced barrel sold decreased 48% from $21.99 for the three months ended June 30, 2023, to $11.33 for the three months ended June 30, 2024. The decrease was due to lower average per barrel sold sales prices and higher crude oil and feedstock prices during the three months ended June 30, 2024. Adjusted refinery gross margin per barrel does not include 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, operating expenses, and depreciation and amortization. See “Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles” following Item 3 of Part I of this Quarterly Report on Form 10-Q for a reconciliation to the income statement of sale prices of products sold and cost of products purchased.

Operating Expenses

Operating expenses, exclusive of depreciation and amortization, increased 8% from $546.8 million for the three months ended June 30, 2023, to $591.3 million for the three months ended June 30, 2024, primarily due to increased maintenance and personnel costs during the three months ended June 30, 2024.

Selling, General and Administrative Expenses

Selling, general and administrative expenses decreased 18% from $127.4 million for the three months ended June 30, 2023, to $104.9 million for the three months ended June 30, 2024, primarily due to lower professional costs and a decrease in acquisition integration and regulatory costs as compared to the prior period. We incurred$0.9 million and $3.5 million in acquisition integration and regulatory costs during the three months ended June 30, 2024 and 2023, respectively.

Depreciation and Amortization Expenses

Depreciation and amortization increased 8% from $189.4 million for the three months ended June 30, 2023, to $205.3 million for the three months ended June 30, 2024, principally due to depreciation and amortization attributable to additional capitalized refinery turnaround costs and capitalized improvement projects as compared to the prior period.

Interest Income

Interest income was $18.5 million for the three months ended June 30, 2024, compared to $17.6 million for the three months ended June 30, 2023. The increase in interest income was primarily due to higher interest rates on cash investments during the three months ended June 30, 2024.

Interest Expense

Interest expense was $45.4 million for the three months ended June 30, 2024, compared to $47.0 million for the three months ended June 30, 2023. This decrease was primarily due to a reduction in total debt outstanding as compared to the prior period.

Gain (Loss) on Foreign Currency Transactions

Remeasurement adjustments resulting from the foreign currency conversion of the intercompany financing notes payable by Petro-Canada Lubricants Inc. net of mark-to-market valuations on foreign exchange forward contracts with banks which hedge the foreign currency exposure on these intercompany notes were a net loss of $0.4 million and a net gain of $0.7 million for the three months ended June 30, 2024 and 2023, respectively. For the three months ended June 30, 2024 and 2023, the change in foreign currency transactions included a gain of $3.5 million and a loss of $8.7 million, respectively, on foreign exchange forward contracts (utilized as an economic hedge).

Income Taxes

For the three months ended June 30, 2024, we recorded income tax expense of $24.0 million compared to $145.9 million for the three months ended June 30, 2023. This decrease was principally due to lower pre-tax income during the three months ended June 30, 2024, compared to the same period of 2023. Our effective tax rates were 13.5% and 21.4% for the three months ended June 30, 2024 and 2023, respectively. The difference between the U.S. federal statutory rate and the effective tax rate for the three months ended June 30, 2024, is primarily due to the relationship between pre-tax results and non-taxable permanent differences. The difference in the U.S. federal statutory rate and the effective tax rate for the three months ended June 30, 2023, was primarily due to the impact of federal tax credits and the relationship between pre-tax results and the earnings attributable to the noncontrolling interest that is not included in income for tax purposes.

Results of Operations – Six Months Ended June 30, 2024 Compared to Six Months Ended June 30, 2023

Summary

Net income attributable to HF Sinclair stockholders for the six months ended June 30, 2024 was $466.5 million ($2.38 per basic and diluted share), a $394.5 million decrease compared to net income of $860.9 million ($4.40 per basic and diluted share) for the six months ended June 30, 2023. The decrease in net income was principally driven by lower adjusted refinery gross margins in both the West and Mid-Continent regions, partially offset by higher refined product sales volumes. Lower of cost or market inventory reserve adjustments related to our Refining and Renewables segments inventories increased pre-tax earnings by $222.5 million for the six months ended June 30, 2024 and decreased pre-tax earnings by $39.7 million for the six months ended June 30, 2023. Adjusted refinery gross margins for the six months ended June 30, 2024, decreased to $11.99 per produced barrel sold as compared to $22.55 for the six months ended June 30, 2023.

Depreciation and Amortization Expenses

Depreciation and amortization increased 11% from $363.3 million for the six months ended June 30, 2023, to $404.0 million for the six months ended June 30, 2024, principally due to additional capitalized refinery turnaround costs and capitalized improvement projects as compared to the prior period.

Interest Income

Interest income was $40.7 million for the six months ended June 30, 2024, compared to $37.5 million for the six months ended June 30, 2023. The increase in interest income was primarily due to higher interest rates on cash investments.

Interest Expense

LIQUIDITY AND CAPITAL RESOURCES

HF Sinclair Credit Agreement

We have a $1.65 billion senior unsecured revolving credit facility maturing in April 2026 (the “HF Sinclair Credit Agreement”). The HF Sinclair Credit Agreement may be used for revolving credit loans and letters of credit from time to time and is available to fund general corporate purposes. At June 30, 2024, we were in compliance with all covenants, had no outstanding borrowings and had outstanding letters of credit totaling$0.3 million under the HF Sinclair Credit Agreement.

HEP Credit Agreement

Through our wholly owned subsidiary, HEP, we have a$1.2 billion senior secured revolving credit facility maturing in July 2025 (the “HEP Credit Agreement”). The HEP Credit Agreement is available to fund capital expenditures, investments, acquisitions, distribution payments, working capital and for general corporate purposes. It is also available to fund letters of credit up to a $50.0 million sub-limit and has an accordion feature that allows us to increase the commitments under the HEP Credit Agreement up to a maximum amount of $1.7 billion.

In connection with the consummation of the HEP Merger Transaction, we amended the HEP Credit Agreement to, among other things, (a) provide a guaranty from us and terminate all guaranties from subsidiaries of HEP, (b) amend the definition of “Investment Grade Rating” (as defined in the HEP Credit Agreement) to reference the credit rating of our senior unsecured indebtedness, (c) eliminate the requirement to deliver separate audited and unaudited financial statements for HEP and its subsidiaries and only provide certain segment-level reporting for HEP with any compliance certificate delivered in accordance with the HEP Credit Agreement and (d) amend certain covenants to eliminate certain restrictions on (i) amendments to intercompany contracts, (ii) transactions with us and our subsidiaries and (iii) investments in and contributions, dividends, transfers and distributions to us and our subsidiaries.

During the six months ended June 30, 2024, we had net repayments of $105.5 million under the HEP Credit Agreement. At June 30, 2024, we were in compliance with all of its covenants, had outstanding borrowings of $350.0 millionand no outstanding letters of credit under the HEP Credit Agreement.

HEP Senior Notes Exchange

On December 4, 2023, we completed our offers to exchange any and all outstanding HEP 5.000% senior notes maturing February 2028 (the “HEP 5.000% Senior Notes”) and HEP 6.375% senior notes maturing April 2027 (the “HEP 6.375% Senior Notes”) (and, collectively, the “HEP Senior Notes”) for HF Sinclair 5.000% senior notes maturing February 2028 (the “HF Sinclair 5.000% Senior Notes”) and HF Sinclair 6.375% senior notes maturing April 2027 (the “HF Sinclair 6.375% Senior Notes”) (and, collectively, the “New HF Sinclair Senior Notes”) to be issued by HF Sinclair with registration rights and cash. In connection with the exchange offers, we amended the indenture governing the HEP Senior Notes to eliminate (i) substantially all of the restrictive covenants, (ii) certain of the events which may lead to an “Event of Default,” (iii) the SEC reporting covenant and (iv) the requirement of HEP to offer to purchase the HEP Senior Notes upon a change of control.

The New HF Sinclair Senior Notes are unsecured and unsubordinated obligations of ours and rank equally with all our other existing and future unsecured and unsubordinated indebtedness. Each series of the New HF Sinclair Senior Notes has the same interest rate, interest payment dates, maturity date and redemption terms as the corresponding series of HEP Senior Notes. The New HF Sinclair Senior Notes were issued in exchange for the HEP Senior Notes pursuant to a private exchange offer exempt from registration under the Securities Act of 1933, as amended. This exchange was part of a broader corporate strategy, including the HEP Merger Transaction, which closed on December 1, 2023.

HF Sinclair 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 and then leased back the precious metals catalyst in exchange for cash. The volume of the precious metals catalyst and the lease rate are fixed over the term of each lease, and the lease payments are recorded as interest expense. The current leases mature in one year or less. Upon maturity, we must either satisfy the obligation at fair market value or refinance to extend the maturity.

HF Sinclair may, from time to time, issue letters of credit pursuant to uncommitted letters of credit facilities with its lenders. At June 30, 2024, there wereno letters of credit outstanding under such credit facilities.

See Note 9 “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 liquidity needs for the foreseeable future. We expect that, to the extent necessary, we can raise additional funds from time to time through equity or debt financings in the public and private capital markets. Further, we may, from time to time, seek to retire some or all of our outstanding debt or 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. In addition, components of our long-term growth strategy include the optimization of existing units at our facilities and the selective acquisition of complementary assets for our operations intended to 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 May 2024 Share Repurchase Program.

Our liquidity was approximately $3.37 billion at June 30, 2024, consisting of cash and cash equivalents of $866.3 million, an undrawn $1.65 billion credit facility under the HF Sinclair Credit Agreement and $850.0 million remaining availability under the HEP 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 conservative, 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.

On April 1, 2024, we repurchased 5,000,000 shares of our outstanding common stock from REH Company in a privately negotiated transaction under the share repurchase program approved by our Board of Directors in August 2023 (the “August 2023 Share Repurchase Program”) and pursuant to the Stock Purchase Agreement, dated April 1, 2024 (the “April 2024 Stock Purchase Agreement”), between us and REH Company. The price paid under the April 2024 Stock Purchase Agreement was $59.22 per share resulting in an aggregate purchase price of $296.1 million. The purchase price was funded with cash on hand.

On May 7, 2024, our Board of Directors approved the May 2024 Share Repurchase Program, which replaced all existing share repurchase programs, including the approximately $214.2 million remaining under the August 2023 Share Repurchase Program. The May 2024 Share Repurchase Program authorizes us to repurchase common stock in the open market or through privately negotiated transactions. Privately negotiated repurchases from REH are also authorized under the May 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 May 2024 Share Repurchase Program may be discontinued at any time by our Board of Directors.

On May 14, 2024, we repurchased 1,348,435 shares of our outstanding common stock from REH Company in a privately negotiated transaction under the May 2024 Share Repurchase Program and pursuant to the Stock Purchase Agreement, dated May 14, 2024 (the “May 2024 Stock Purchase Agreement”), between us and REH Company. The price paid under the May 2024 Stock Purchase Agreement was $55.62 per share resulting in an aggregate purchase price of $75.0 million. The purchase price was funded with cash on hand.

During the six months ended June 30, 2024, we made open market and privately negotiated purchases of 7,930,742 shares for$462.2 million under the August 2023 Share Repurchase Program, of which 6,516,326 shares were repurchased for$381.1 million pursuant to privately negotiated repurchases from REH Company. During the six months ended June 30, 2024, we made open market and privately negotiated purchases of 1,348,435 shares for$75.0 million under the May 2024 Share Repurchase Program, of which 1,348,435 shares were repurchased for$75.0 million pursuant to privately negotiated repurchases from REH Company.

Cash Flows – Operating Activities

Net cash flows provided by operating activities were $542.8 million for the six months ended June 30, 2024, compared to $667.7 million for the six months ended June 30, 2023, a decrease of $124.9 million primarily driven by a decrease in net income, partially offset by changes in working capital combined with lower turnaround spend during the six months ended June 30, 2024. Changes in working capital increased operating cash flows by$28.0 million for thesix months ended June 30, 2024, and decreased operating cash flows by $374.0 million for the six months ended June 30, 2023. Additionally, for the six months ended June 30, 2024, turnaround expenditures were $169.3 million compared to $347.1 million for the six months ended June 30, 2023.

Cash Flows – Investing Activities and Planned Capital Expenditures

For the six months ended June 30, 2024, our net cash flows used for investing activities were $173.5 million. Cash expenditures for properties, plants and equipment for the six months ended June 30, 2024, were $173.3 million.

For the six months ended June 30, 2023, our net cash flows used for investing activities were $176.3 million. Cash expenditures for properties, plants and equipment for the six months ended June 30, 2023, were $180.3 million.

Each year, our Board of Directors approves our annual capital budget, which includes specific projects that management is authorized to undertake. When conditions warrant or as new opportunities arise, additional projects may be approved. The funds appropriated for a particular capital project may be expended over a period of several years, depending on the time required to complete the project. Therefore, our planned capital expenditures for a given year consist of expenditures appropriated in that year’s capital budget plus expenditures for projects appropriated in prior years that have not yet been completed. Refinery turnaround spending is amortized over the useful life of the turnaround.

The refining industry is capital-intensive and requires ongoing investments to sustain our refining operations. This includes the replacement of, or rebuilding, refinery units and components that extend their useful life. We also invest in projects that improve operational reliability and profitability via enhancements that improve refinery processing capabilities as well as production yield and flexibility. Our capital expenditures also include projects related to renewable diesel, environmental, health and safety compliance and include initiatives as a result of federal and state mandates.

Our refinery operations and related emissions are highly regulated at both federal and state levels, and we invest in our facilities as needed to remain in compliance with these standards. Additionally, when faced with new emissions or fuel standards, we seek to execute projects that facilitate compliance and also improve the operating costs and/or yields of associated refining processes.

Expected capital and turnaround cash spending for 2024 is as follows:

Contractual Obligations and Commitments

During the six months ended June 30, 2024, we had net repayments of $105.5 million, resulting in $350.0 million of outstanding borrowings under the HEP Credit Agreement at June 30, 2024.

There were no other significant changes to our long-term contractual obligations during this period.

CRITICAL ACCOUNTING ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities as of the date of the financial statements. Actual results may differ from these estimates under different assumptions or conditions.

Our significant accounting policies are described 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, 2023. Certain critical accounting policies that materially affect the amounts recorded in our consolidated financial statements include assessing contingent liabilities for probable losses.

Contingencies

We are subject to proceedings, lawsuits and other claims related to environmental, labor, product and other matters. We are required to assess the likelihood of any adverse judgments or outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for these contingencies is made after careful analysis of each individual issue. The required reserves may change in the future due to new developments in each matter or changes in approach, such as a change in settlement strategy when dealing with these matters.

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.

Commodity Price Risk Management

Our primary market risk is commodity price risk. We are exposed to market risks related to the volatility in crude oil and refined products, as well as 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 purchase and sales 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 June 30, 2024, we have the following notional contract volumes related to all outstanding derivative instruments used to mitigate commodity price and foreign currency risk:

(1)Represents an embedded derivative within our precious metals catalyst financing arrangements, which may be refinanced or require repayment under certain conditions. See Note 9 “Debt” in the Notes to Consolidated Financial Statements for additional information on these financing arrangements.

The following sensitivity analysis provides the hypothetical effects of market price fluctuations to the commodity hedged under our derivative contracts:

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 Senior Notes, HollyFrontier Senior Notes and HEP Senior Notes (each as set forth in Note 9 “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 June 30, 2024, is presented below:

For the variable rate HF Sinclair Credit Agreement and HEP Credit Agreement, changes in interest rates would affect cash flows, but not the fair value. At June 30, 2024, outstanding borrowings under the HEP Credit Agreement were $350.0 million, and no borrowings were outstanding under the HF Sinclair Credit Agreement. A hypothetical 10% change in interest rates applicable to the HEP Credit Agreement would not materially affect cash flows.

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, which are 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.

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

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.
