In the normal course of business, we are exposed to market risk, including changes in interest rates, prices of certain commodities and foreign currency exchange rate risks. We use hedge agreements to manage a portion of our risks related to interest rates. While we are exposed to credit risk in the event of non-performance by counterparties to our hedge agreements, in all cases such counterparties are highly rated financial institutions and we do not anticipate non-performance under current market conditions. We do not hold or issue derivative financial instruments for trading purposes. We monitor our hedge positions by regularly evaluating the positions at market and by performing sensitivity analyses over the unhedged variable rate debt positions. At June 30, 2026, our derivative instruments included one interest rate swap agreement that effectively fixes the interest rate on the applicable notional amounts of our variable rate debt as follows (dollars in thousands of U.S. dollars): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fixed ​ ​ ​ Variable ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Notional ​ Interest ​ Interest Rate ​ ​ ​ Expiration Date Entered ​ Amount ​ Rate Paid (a) ​ Received ​ Effective Date (b) ​ Date December 2018 ​ $ 200,000 ​ 2.7715 % 1-month term SOFR ​ November 2022 ​ July 2027 (a) Plus applicable margin. (b) In October 2022, we amended the reference rate in our outstanding interest rate swap contract to replace One-Month LIBOR with One-Month term SOFR and certain credit spread adjustments. We did not record any gains or losses upon the conversion of the reference rates in this interest rate swap contract, and we believe this amendment will not have a material impact on our Condensed Consolidated Financial Statements. Under derivatives and hedging guidance, the interest rate swap agreements are considered cash flow hedges for a portion of our variable rate debt, and we apply hedge accounting to account for these instruments. The notional amounts and all other significant terms of the swap agreements are matched to the provisions and terms of the variable rate debt being hedged. We have performed sensitivity analyses to determine how market rate changes will affect the fair value of our unhedged floating rate debt. Such an analysis is inherently limited in that it reflects a singular, hypothetical set of assumptions. Actual market movements may vary significantly from our assumptions. Fair value sensitivity is not necessarily indicative of the ultimate cash flow or earnings effect we would recognize from the assumed market rate movements. We are exposed to cash flow risk due to changes in interest rates with respect to the unhedged floating rate balances owed at June 30, 2026 and December 31, 2025, of $2.075 billion and $2.182 billion, respectively, including floating rate debt under our Revolving Credit Agreement. A one percentage point increase in interest rates on our variable-rate debt at June 30, 2026 and December 31, 2025, would decrease our annual pre-tax income by approximately $20.7 million and $21.8 million, respectively. All of our remaining debt instruments are at fixed rates, or effectively fixed under the interest rate swap agreement described above; therefore, changes in market interest rates under these instruments would not significantly impact our cash flows or results of operations, subject to counterparty default risk. The market price of diesel fuel is unpredictable and can fluctuate significantly. Because of the volume of fuel we purchase each year, a significant increase in the price of fuel could adversely affect our business and reduce our operating margins. To manage a portion of this risk, we periodically enter into fuel hedge agreements related to forecasted diesel 56 Table of Contents fuel purchases, and we also enter into fixed price fuel purchase contracts. At June 30, 2026, we had no fuel hedge agreements in place; however, we have entered into fixed price diesel fuel purchase contracts for the six months ended June 30, 2026 as described below. For the year ending December 31, 2026, we expect to purchase approximately 92.2 million gallons of diesel fuel, of which 50.4 million gallons will be purchased at market prices and 41.8 million gallons will be purchased under our fixed price diesel fuel purchase contracts. We have performed sensitivity analyses to determine how market rate changes will affect the fair value of our unhedged, market rate diesel fuel purchases. Such an analysis is inherently limited in that it reflects a singular, hypothetical set of assumptions. Actual market movements may vary significantly from our assumptions. Fair value sensitivity is not necessarily indicative of the ultimate cash flow or earnings effect we would recognize from the assumed market rate movements. During the six month period of July 1, 2026 to December 31, 2026, we expect to purchase approximately 25.2 million gallons of diesel fuel at market prices; therefore, a $0.10 per gallon increase in the price of diesel fuel over the remaining six months in 2026 would decrease our pre-tax income during this period by approximately $2.5 million. We market a variety of recyclable materials, including compost, cardboard, mixed paper, plastic containers, glass bottles and ferrous and aluminum metals. We own and operate recycling operations and market collected recyclable materials to third parties for processing before resale. Where possible, to reduce our exposure to commodity price risk with respect to recycled materials, we have adopted a pricing strategy of charging collection and processing fees for recycling volume collected from third parties. In the event of a decline in recycled commodity prices, a 10% decrease in average recycled commodity prices from the average prices that were in effect during the six months ended June 30, 2026 and 2025, would have had a $11.3 million and $12.6 million impact on revenues, respectively. We have operations in Canada and, where significant, we have quantified and described the impact of foreign currency translation on components of income, including operating revenue and operating costs. However, the impact of foreign currency has not materially affected our results of operations in 2026 or 2025. A $0.01 change in the Canadian dollar to U.S. dollar exchange rate would impact our annual revenue and EBITDA by approximately $20.0 million and $9.0 million, respectively. ​ 57 Table of Contents
