Item 7A. Quantitative and Qualitative Disclosures About Market Risk Interest Rate Risk We are exposed to market risk related to changes in interest rates. Our primary exposure to interest rate risk results from the cash equivalents and short-term investments in our investment portfolio. Our primary objectives in managing our investment portfolio are to preserve principal, maintain proper liquidity to meet operating needs and maximize yields. At any time, significant changes in interest rates can affect the fair value of the investment portfolio and its interest earnings. Currently, we do not hedge these interest rate exposures. As of December 31, 2025, our cash equivalents and short-term investments primarily consisted of money market mutual funds and U.S. government and agency securities. If market interest rates were to increase immediately and uniformly by 100 basis points, or one percentage point, from levels at December 31, 2025, we estimate that the increase would have resulted in a hypothetical decline of $0.1 million in the net fair value of our interest-sensitive securities. Effects of Inflation Inflation generally affects us by increasing our cost of labor and research and development contract costs. We do not believe inflation has had a material effect on our consolidated financial statements included in this Annual Report. 74 Table of Contents
