HF Sinclair Corp

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

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 the price of 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 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 September 30, 2025, we have the following notional amounts 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 11 “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:

Financial information of the counterparties is reviewed in order to evaluate 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.

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 described in Note 11 “Debt” in the Notes to Consolidated Financial Statements), changes in interest rates will generally affect 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 September 30, 2025, is presented below:

For the variable rate under the HF Sinclair Credit Agreement, changes in interest rates would affect cash flows, but not the fair value. At September 30, 2025, there were no amounts outstanding under the HF Sinclair Credit Agreement. A hypothetical 10% change in interest rate 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.
