General We are exposed to market risk attributable to changes in interest rates, foreign currency exchange rates and fuel prices. We attempt to minimize these risks through a combination of our normal operating and financing activities and through the use of derivatives. The financial impacts of these derivative instruments are primarily offset by corresponding changes in the underlying exposures being hedged. We achieve this by closely matching the notional, term and conditions of the derivatives with the underlying risk being hedged. We do not hold or issue derivatives for trading or other speculative purposes. Derivative positions are monitored using techniques including market valuations and sensitivity analyses. Interest Rate Risk As of June 30, 2026 and December 31, 2025, 90% of our debt was fixed and 10% was variable. Based on our June 30, 2026 outstanding variable rate debt balance, a one percentage point increase in annual Term SOFR interest rates would increase our annual interest expense by approximately $15.3 million excluding the effects of capitalization of interest. Foreign Currency Exchange Rate Risk We use foreign currency derivatives to hedge the exposure to volatility in foreign currency exchange rates related to our ship construction contracts denominated in euros. As of June 30, 2026, the payments not hedged aggregated €13.3 billion, or $15.2 billion based on the euro/U.S. dollar exchange rate as of June 30, 2026. As of December 31, 2025, the payments not hedged aggregated €16.4 billion, or $19.3 billion, based on the euro/U.S. dollar exchange rate as of December 31, 2025. The change from December 31, 2025 to June 30, 2026 was primarily due to the addition of foreign currency derivatives. We estimate that a 10% change in the euro as of June 30, 2026 would result in a $1.5 billion change in the U.S. dollar value of the foreign currency denominated remaining payments. Additionally, we borrow certain debt denominated in euros in connection with our newbuild program. Net gains and losses recognized in other income (expense), net from exchange rate remeasurements on euro-denominated debt were gains of $32.7 million and losses of $121.9 million for the three months ended June 30, 2026 and 2025, respectively, and gains of $70.3 million and losses of $137.9 million for the six months ended June 30, 2026 and 2025, respectively. As of June 30, 2026, the total aggregate euro-denominated debt balance not hedged was approximately €2.1 billion, or $2.4 billion based on the euro/U.S. dollar exchange rate as of June 30, 2026. As of December 31, 2025, the total aggregate euro-denominated debt balance not hedged was approximately €1.7 billion, or $2.0 billion based on the euro/U.S. dollar exchange rate as of December 31, 2025. The change from December 31, 2025 to June 30, 2026 was primarily due to the delivery of Norwegian Luna, partially offset by additional foreign exchange forwards. We estimate that a 10% change in the euro as of June 30, 2026 would result in a $240.1 million change in the U.S. dollar value of the foreign currency denominated debt principal not hedged. 40 Table of Contents Fuel Price Risk Our exposure to market risk for changes in fuel prices relates to the forecasted purchases of fuel on our ships. Fuel expense, as a percentage of our total cruise operating expense, was 13.8% and 10.8% for the three months ended June 30, 2026 and 2025, respectively, and was 13.1% and 12.0% for the six months ended June 30, 2026 and 2025, respectively. We use fuel derivative agreements to mitigate the financial impact of fluctuations in fuel prices, and as of June 30, 2026, we had hedged approximately 52% and 38% of our remaining 2026 and 2027 projected metric tons of fuel purchases, respectively. As of December 31, 2025, we had hedged approximately 51% and 22% of our 2026 and 2027 projected metric tons of fuel purchases, respectively. The percentage of fuel purchases hedged changed between December 31, 2025 and June 30, 2026 primarily due to additional fuel swaps. ​ We estimate that a 10% increase in our weighted-average fuel price would increase our anticipated 2026 fuel expense by $39.7 million. This increase would be offset by an increase in the fair value of all our fuel swap agreements of $18.5 million. Fair value of our derivative contracts is derived using valuation models that utilize the income valuation approach. These valuation models take into account the contract terms such as maturity, as well as other inputs such as fuel types, fuel curves, creditworthiness of the counterparty and the Company, as well as other data points. ​
