Interest rate risk The risk associated with fluctuating interest rates is primarily limited to our cash equivalents and debt issued under the Loan Agreement, which are carried at quoted market prices and the prime rate, respectively. We do not currently use or plan to use financial derivatives in our investment portfolio. Foreign currency exchange rate risk Portions of our revenue and operating expenses that are incurred outside the U.S. are denominated in foreign currencies and subject to fluctuations due to changes in foreign currency exchange rates, particularly changes in the Euro. Additionally, fluctuations in foreign currency exchange rates may cause us to recognize transaction gains and losses in our condensed consolidated statements of operations and comprehensive loss. To date, realized gains and losses from foreign currency transactions have not been material to our condensed consolidated financial statements, and we have not engaged in any foreign currency hedging transactions. As our international operations grow, we will continue to reassess our approach to managing the risks relating to fluctuations in currency rates. Inflation risk Inflationary factors, such as increases in our cost of goods sold and operating expenses, may adversely affect our operating results. Although we do not believe that inflation has had a material impact on our financial position or results of operations to date, a high rate of inflation in the future may have an adverse effect on our ability to maintain and increase our gross margin and selling and marketing and operating expenses as a percentage of our revenue if the selling prices of our products do not increase as much as or more than these increased costs. Credit risk As of June 30, 2026 and December 31, 2025, our cash and cash equivalents were maintained with financial institutions which we believe have sufficient assets and liquidity to conduct their operations in the ordinary course of business with little or no credit risk to us; however, our cash balances were in excess of insured limits.
