Interest Rate Risk Long-Term Debt As of June 28, 2026, we had $3.75 billion in principal amount of fixed-rate long-term debt outstanding, with a fair value of $3.16 billion. The fair value of our Senior Notes is subject to interest rate risk and market risk. Generally, the fair value of Senior Notes will increase as interest rates fall and decrease as interest rates rise. The interest and market value changes affect the fair value of our Senior Notes but do not impact our financial position, cash flows, or results of operations due to the fixed nature of the debt obligations. We do not carry the Senior Notes at fair value but present the fair value of the principal amount of our Senior Notes for disclosure purposes. Foreign Currency Exchange (“FX”) Risk We conduct business on a global basis in several major international currencies. As such, we are potentially exposed to adverse as well as beneficial movements in foreign currency exchange rates. The majority of our revenues and expenses are denominated in U.S. dollars. However, we are exposed to foreign currency exchange rate fluctuations on non-U.S. dollar transactions or cash flows. We enter into foreign currency forward contracts to minimize the short-term impact of exchange rate fluctuations on certain foreign currency denominated monetary assets and liabilities, primarily cash, third-party accounts receivable, accounts payable, and intercompany receivables and payables. In addition, we hedge certain anticipated foreign currency cash flows. To protect against adverse movements in value of anticipated non-U.S. dollar transactions or cash flows, we enter into foreign currency forward and option contracts that generally expire within 12 months and no later than 24 months. The option contracts include collars, an option strategy that is comprised of a combination of a purchased put option and a written call option with the Lam Research Corporation 2026 10-K 39 Table of Contents same expiration dates and notional amounts but with different strike prices. These foreign currency hedge contracts are designated as cash flow hedges and are carried on our balance sheet at fair value, with the effective portion of the contracts’ gains or losses included in accumulated other comprehensive income (loss) and subsequently recognized in earnings in the same period the hedged revenue and/or expense is recognized. The unrealized loss of our outstanding forward and option contracts that are designated as cash flow hedges, as of June 28, 2026, and the change in fair value of these cash flow hedges assuming a hypothetical foreign currency exchange rate movement of plus or minus 10 percent and plus or minus 15 percent are not significant. We also enter into foreign currency forward contracts to offset the gains and losses generated by the remeasurement of certain non-U.S.-dollar denominated monetary assets and liabilities, primarily cash, third-party accounts receivable, accounts payable, and intercompany receivables and payables. The change in fair value of these balance sheet derivative instruments is recorded into earnings as a component of other income (expense), net, and offsets the change in fair value of the foreign currency denominated monetary assets and liabilities also recorded in other income (expense), net, assuming the derivative instruments fully cover the value of the foreign currency denominated monetary assets and liabilities. The unrealized loss of our balance sheet derivative instruments as of June 28, 2026, and the change in fair value of these contacts, assuming a hypothetical foreign currency exchange rate movement of plus or minus 10 percent and plus or minus 15 percent are not significant. These changes in fair values would be offset in other income (expense), net, by corresponding changes remeasurement gains or losses on foreign currency denominated monetary assets and liabilities, assuming the derivative instruments fully cover the value of the foreign currency denominated monetary assets and liabilities.
