Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

PCA is exposed to the impact of commodity price changes, interest rate changes, and changes in the market value of its financial instruments. To manage these risks, we may from time to time enter into transactions, including certain physical commodity transactions, that are determined to be derivatives. As of December 31, 2025, we are party to certain physical commodity transactions related to natural gas supply contracts. For a discussion of derivatives and hedging activities, see Note 2, Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements in “Part II, Item 8. Financial Statements and Supplementary Data” of this Form 10-K.

At December 31, 2025, the interest rates on approximately 75% of PCA’s debt are fixed. A one percent increase in interest rates related to variable-rate debt would have resulted in an increase in interest expense and a corresponding decrease in income before taxes of approximately $10 million annually.
