Commodity Price Risk We manage our commodity price risk for coal sales through the use of coal supply agreements. Refer to “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting Our Results of Operations” for information on our sales commitments for 2026. We have exposure to commodity price risk for supplies that are used directly or indirectly in the normal course of production such as diesel fuel, steel and other items such as explosives. We manage our risk for these items through strategic sourcing contracts in normal quantities with our suppliers. The market price of diesel fuel fluctuates due to changes in production, seasonality, and other market factors generally outside of our control, including the ongoing conflict between the U.S. and Iran. Increased fuel costs may have a negative impact on our results of operations and financial condition. We expect to purchase approximately 23.0 million gallons of diesel fuel in 2026 at market rates. Interest Rate Risk As of June 30, 2026, we maintain a senior secured asset-based revolving credit facility, under which we may borrow up to $225.0 million (less amounts outstanding for LCs). Any cash borrowings under the facility would bear a floating rate of interest. No cash borrowings were outstanding under the facility as of June 30, 2026 or December 31, 2025. Refer to Note 8 to 39 Table of Contents the Condensed Consolidated Financial Statements for additional information. Also refer to the Note 13 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2025 for discussion on the terms of our long-term debt. As of June 30, 2026 and December 31, 2025, we had investments in trading securities of $65.3 million and $83.9 million, respectively, primarily consisting of U.S. government securities. While the fair value of these investments is exposed to risk with respect to changes in market rates of interest, we do not believe exposure to changes in interest rates is material to our Condensed Consolidated Financial Statements. We manage risk by investing in shorter term highly rated debt obligations. As of June 30, 2026 and December 31, 2025, the remaining maturities of our acquired debt securities was less than 12 months. Foreign Currency Risk Our transactions are denominated in U.S. dollars, and, as a result, we do not have material exposure to currency exchange-rate risks. However, our coal is sold internationally in U.S. dollars and, as a result, general economic conditions in foreign markets and changes in foreign currency exchange rates may provide our foreign competitors with a competitive advantage. If our competitors’ currencies decline against the U.S. dollar or against our foreign customers’ local currencies, those competitors may be able to offer lower prices for coal to customers. Furthermore, if the currencies of our overseas customers were to significantly decline in value in comparison to the U.S. dollar, those customers may seek decreased prices for the coal we sell to them. Consequently, currency fluctuations could adversely affect the competitiveness of our coal in international markets, which could have a material adverse effect on our business, financial condition, results of operations, and cash flows.
