Interest Rate Risk The primary objective of our investment activities is to preserve principal and liquidity while at the same time maximizing the income we receive without significantly increasing risk. To achieve this objective, we may invest in money market funds, U.S. Treasury notes, and high-quality marketable debt instruments of corporations and government sponsored enterprises with contractual maturity dates of generally less than two years, in accordance with an investment policy approved by our audit committee. Some of the financial instruments that we invest in could be subject to market risk, meaning that a change in prevailing interest rates may cause the value of the instruments to fluctuate. For example, if we purchase a security that was issued with a fixed interest rate and the prevailing interest rate later rises, the value of that security will probably decline. To minimize this risk, we intend to maintain a portfolio which may include a variety of securities, including money market funds, government debt securities, certificates of deposit and commercial paper, all with various maturity dates. As of June 30, 2026, we had cash, cash equivalents and investments of $387.6 million, consisting of interest-bearing money market funds, certificates of deposit, securities issued by the U.S. Treasury and marketable debt instruments of government-sponsored enterprises. Due to the nature of our cash equivalents and investments, an immediate 100 basis point change in interest rates would not have a material effect on their fair market value. Inflation generally affects us by increasing our cost of labor, clinical trial and manufacturing costs. We do not believe that inflation, interest rate changes or exchange rate fluctuations had a significant impact on our results of operations for any periods presented herein.
