Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risks that may result from changes in interest rates, foreign currency exchange rates and prices of equity instruments as well as changes in general economic conditions in the countries where we conduct business. To reduce certain of these risks, we enter into various types of foreign currency and interest rate derivative hedging transactions as part of our risk management program. We do not use derivatives for speculative trading purposes.

In the discussion that follows, we assumed a hypothetical change in interest rates of 100 basis points from those as of December 31, 2025 and 2024. Except as noted below, we also assumed a hypothetical 20% change in foreign currency exchange rates against the U.S. dollar based on its position relative to other currencies as of December 31, 2025 and 2024.

Interest-rate-sensitive financial instruments

Our portfolio of available-for-sale investments as of December 31, 2025 and 2024, was composed almost entirely of U.S. Treasury securities and money market mutual funds. The fair values of our available-for-sale investments were $8.5 billion and $11.5 billion as of December 31, 2025 and 2024, respectively. Duration is a sensitivity measure that can be used to approximate the change in the value of a security that will result from a 100 basis point change in interest rates. Applying a duration model, a hypothetical 100 basis point increase in interest rates as of December 31, 2025 and 2024, would not have resulted in a material reduction in the fair values of these securities. In addition, a hypothetical 100 basis point decrease in interest rates as of December 31, 2025 and 2024, would not result in a material effect on income in the respective ensuing year.

As of December 31, 2025, we had outstanding notes with an aggregate carrying value of $52.8 billion and an aggregate fair value of $51.0 billion. As of December 31, 2024, we had outstanding notes with an aggregate carrying value of $58.3 billion and an aggregate fair value of $54.9 billion. Our outstanding notes were composed of debt with fixed interest rates. Changes in interest rates do not affect interest expense on fixed-rate debt. Changes in interest rates would, however, affect the fair values of fixed-rate debt. A hypothetical 100 basis point decrease in interest rates relative to interest rates as of December 31, 2025 and 2024, would have resulted in increases of $4.4 billion and $4.7 billion, respectively, in the aggregate fair values of our outstanding debt on these dates. The sensitivity analysis of the notes does not consider the impact that hypothetical changes in interest rates would have on related interest rate swap contracts and cross-currency swap contracts, discussed below. In addition, the analysis above does not include our term loans, which had a carrying value of $1.8 billion at both December 31, 2025 and 2024. The fair value of our term loan is approximated at its carrying value as this debt instrument bears interest at a floating rate.

To achieve a desired mix of fixed-rate and floating-rate debt, we entered into interest rate swap contracts that qualified and were designated for accounting purposes as fair value hedges for certain of our fixed-rate debt. These interest rate swap contracts effectively converted a fixed-rate interest coupon to a floating-rate SOFR-based coupon over the terms of the respective notes. Interest rate swap contracts with an aggregate notional amount of $6.7 billion were outstanding as of both December 31, 2025 and 2024. A hypothetical 100 basis point increase in interest rates relative to interest rates as of December 31, 2025 and 2024, would have resulted in reductions in fair values of approximately $240 million and $220 million, respectively, on our interest rate swap contracts on these dates. Analysis of the interest rate swap contracts does not consider the impact that hypothetical changes in interest rates would have on the related fair values of debt that these interest-rate-sensitive instruments were designed to offset.

As of both December 31, 2025 and 2024, we had outstanding cross-currency swap contracts with an aggregate notional amount of $2.7 billion that hedge our foreign-currency-denominated debt and related interest payments. These contracts effectively convert interest payments and principal repayment of this debt to U.S. dollars from euros and pounds sterling and are designated for accounting purposes as cash flow hedges. A hypothetical 100 basis point adverse movement in interest rates relative to interest rates as of December 31, 2025 and 2024, would not have a material effect on the fair values of our cross-currency swap contracts.

Foreign-currency-sensitive financial instruments

Our international operations are affected by fluctuations in the value of the U.S. dollar compared with foreign currencies, predominantly the euro. Increases and decreases in our international product sales from movements in foreign currency exchange rates are partially offset by corresponding increases or decreases in our international operating expenses. Increases and decreases in our foreign-currency-denominated assets from movements in foreign currency exchange rates are partially offset by corresponding increases or decreases in our foreign-currency-denominated liabilities. To further reduce our net exposure to foreign currency exchange rate fluctuations on our results of operations, we enter into foreign currency forward and cross-currency swap contracts.

As of December 31, 2025, we had outstanding euro- and pound-sterling-denominated debt with both a principal carrying value and a fair value of $2.5 billion. As of December 31, 2024, we had outstanding euro- and pound-sterling-denominated debt with both a principal carrying value and a fair value of $2.2 billion. A hypothetical 20% adverse movement in foreign currency exchange rates compared with the U.S. dollar relative to exchange rates as of December 31, 2025, would have resulted in an increase in fair value of this debt of approximately $490 million on this date and a reduction in income in the ensuing year of approximately $490 million. A hypothetical 20% adverse movement in foreign currency exchange rates compared with the U.S. dollar relative to exchange rates as of December 31, 2024, would have resulted in an increase in fair value of this debt of $440 million on this date and a reduction in income in the ensuing year of $450 million. The impact on income from these hypothetical changes in foreign currency exchange rates would be substantially offset by the impact such changes would have on related cross-currency swap contracts, which are in place for the related foreign-currency-denominated debt.

We have cross-currency swap contracts that are designated as cash flow hedges of our debt denominated in euros and pounds sterling with an aggregate notional amount of $2.7 billion as of both December 31, 2025 and 2024. A hypothetical 20% adverse movement in foreign currency exchange rates compared with the U.S. dollar relative to exchange rates on these dates would have resulted in reductions in the fair values of these contracts of approximately $500 million and $450 million on these dates, respectively. The impact of this hypothetical adverse movement in foreign currency exchange rates on ensuing years’ income from these contracts would be fully offset by corresponding hypothetical changes in the carrying amounts of the related hedged debt.

We enter into foreign currency forward contracts that are designated for accounting purposes as cash flow hedges of certain anticipated foreign currency transactions. As of December 31, 2025, the fair values of these contracts were a $195 million asset and a $213 million liability. As of December 31, 2024, the fair values of these contracts were a $420 million asset and an $8 million liability. As of December 31, 2025, we had primarily euro-based open foreign currency forward contracts with an aggregate notional amount of $7.8 billion. As of December 31, 2024, we had primarily euro-based open foreign currency forward contracts with an aggregate notional amount of $7.2 billion. With regard to foreign currency forward contracts that were open as of December 31, 2025, a hypothetical 20% adverse movement in foreign currency exchange rates compared with the U.S. dollar relative to exchange rates as of December 31, 2025, would have resulted in a reduction in fair value of these contracts of approximately $1.5 billion on this date and in the ensuing year, a reduction in income of approximately $800 million. With regard to contracts that were open as of December 31, 2024, a hypothetical 20% adverse movement in foreign currency exchange rates compared with the U.S. dollar relative to exchange rates as of December 31, 2024, would have resulted in a reduction in fair value of these contracts of approximately $1.3 billion on this date and in the ensuing year, a reduction in income of $700 million. The analysis does not consider the impact that hypothetical changes in foreign currency exchange rates would have on anticipated transactions that these foreign-currency-sensitive instruments were designed to offset.

As of December 31, 2025 and 2024, we had open, short-duration, foreign currency forward contracts that mature in one month or less, that had aggregate notional amounts of $240 million and $148 million, respectively, and that hedged fluctuations of certain assets and liabilities denominated in foreign currencies but were not designated as hedges for accounting purposes. These contracts had no material net unrealized gains or losses as of December 31, 2025 and 2024. With regard to these foreign currency forward contracts that were open as of December 31, 2025 and 2024, a hypothetical 5% adverse movement in foreign currency exchange rates compared with the U.S. dollar relative to exchange rates on these dates would not have a material effect on the fair values of these contracts or related income in the respective ensuing years. The analysis does not consider the impact that hypothetical changes in foreign currency exchange rates would have on assets and liabilities that these foreign-currency-sensitive instruments were designed to offset.

Market-price-sensitive financial instruments

As of December 31, 2025 and 2024, we were exposed to price risk on equity securities included in our portfolio of investments, which were acquired primarily for the promotion of business and strategic objectives. These investments include our investment in BeOne, as well as other publicly and privately held small-capitalization stocks and limited partnerships that invest in early-stage biotechnology companies. A 20% decrease in the aggregate value of our equity investment portfolio as of December 31, 2025 and 2024, would result in losses in fair value of approximately $1.4 billion and $950 million, respectively.

Counterparty credit risks

Our financial instruments, including derivatives, are subject to counterparty credit risk, which we consider as part of the overall fair value measurement. Our financial risk management policy limits derivative transactions by requiring that transactions be made only with institutions with minimum credit ratings of A– or equivalent by S&P, Moody’s or Fitch; and it places exposure limits on the amount with any individual counterparty. In addition, we have an investment policy that limits

investments to certain types of debt and money market instruments issued by institutions with investment-grade credit ratings and places restriction on maturities and concentrations by asset class and issuer.
