Item 7A. Quantitative and Qualitative Disclosures about Market Risk We are exposed to market risks in the ordinary course of our business. Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because our investments are in marketable securities. Our marketable securities are subject to interest rate risk and could fall in value if market interest rates increase. However, we believe that our exposure to interest rate risk is not significant as the majority of our investments are short-term in duration and due to the low risk profile of our investments, a 10% change in interest rates would not have a material effect on the total market value of our investment portfolio. We have the ability to hold our marketable securities until maturity, and therefore we would not expect our operating results or cash flows to be affected to any significant degree by the effect of a change in market interest rates on our investments. As of December 31, 2023, we held $114.3 million in cash, cash equivalents and marketable securities, all of which was denominated in U.S. dollar assets, and consisting primarily of cash accounts in banking institutions and investments in money market funds, commercial paper, certificates of deposit, corporate debt securities, United States, or U.S., government debt securities and U.S. government agency securities. We are exposed to market risk related to changes in foreign currency exchange rates, as a result of entering into transactions denominated in currencies other than U.S. dollars. Due to the uncertain timing of expected payments in foreign currencies, we do not utilize any forward exchange contracts. All foreign transactions settle on the applicable spot exchange basis at the time such payments are made. For the year ended December 31, 2023, a majority of our expenditures were denominated in U.S. dollars. A hypothetical 10% change in foreign exchange rates during any of the periods presented would not have had a material impact on our financial statements. Inflation may affect us by increasing our cost of labor, cost of external services, and cost of external goods and raw materials. We do not believe that inflation has had a material effect on our business, financial condition or results of operations for any period presented herein. 105 Table of Contents
