Interest rate risk We are exposed to market risk related to changes in interest rates of our investment portfolio of cash equivalents and short-term investments. As of June 30, 2026, our cash equivalents consisted of money market funds. As of June 30, 2026, our investments consisted of investments in U.S. treasury bills and United States agency securities that have contractual maturities of less than two years. Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. The fair value of our marketable securities is subject to change as a result of potential changes in market interest rates, including changes in federal interest rates. The potential change in fair value for interest rate sensitive instruments has been assessed on a hypothetical 100 basis point adverse movement across all maturities. As of June 30, 2026, we estimate that such hypothetical 100 basis point adverse movement would not result in a material impact on our condensed consolidated results of operations. As of June 30, 2026, we had no debt outstanding and, therefore, are not exposed to interest rate risk with respect to debt. Foreign currency exchange risk All of our employees and our operations are currently located in the United States and our expenses are generally denominated in U.S. dollars. However, we have entered into a limited number of contracts with vendors for research and development services that permit us to satisfy our payment obligations in U.S. dollars (at prevailing exchange rates), but have underlying payment obligations denominated in foreign currencies, including the Euro. We are subject to foreign currency transaction gains or losses on our contracts denominated in foreign currencies. To date, foreign currency transaction gains and losses have not been material to our financial statements and we have not had a formal hedging program with respect to foreign currency. We estimate that a 10% increase or decrease in current exchange rates would not have a material effect on our financial results for the three and six months ended June 30, 2026 and 2025. While we have not engaged in the hedging of our foreign currency transactions to date, we are evaluating the costs and benefits of initiating such a program and may in the future hedge selected significant transactions denominated in currencies other than the U.S. dollar if and/or as we expand our international operations and our risk grows.
