Foreign Exchange Risk We expect that, in the foreseeable future, the majority of our revenues will be denominated in RMB while our expenses are denominated in RMB and other currencies. As a result, we are exposed to risk related to movements between the RMB and such other currencies. In addition, the value of our ADSs and Class A ordinary shares will be affected by the exchange rate between U.S. dollar and RMB because the value of our business is effectively denominated in RMB, while our Class A ordinary shares and the ADSs will be traded in Hong Kong dollars and U.S. dollars, respectively. Furthermore, we have purchased certain financial products issued by banks, the returns of which could also be affected by the exchange rate between RMB and other currencies. The conversion of Renminbi into foreign currencies, including U.S. dollars, is based on rates set by the People’s Bank of China. The Renminbi has fluctuated against the U.S. dollar, at times significantly and unpredictably. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the Renminbi and the U.S. dollar in the future. 162 Table of Contents To the extent that we need to convert U.S. dollars into Renminbi for our operations, appreciation of the Renminbi against the U.S. dollar would have an adverse effect on the RMB amount we receive from the conversion. Conversely, if we decide to convert Renminbi into U.S. dollars for the purpose of making payments for dividends on our Class A ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amounts available to us. Interest Rate Risk Our exposure to interest rate risk relates primarily to the interest rates associated with the outstanding convertible notes we issued and bank loans that bear floating interest rates. The interest rate risk may result from many factors, including, among others, government monetary and tax policies, domestic and international economic and political considerations that are beyond our control. We may incur additional loans or other financing facilities in the future. The objective of interest rate risk management is to minimize financial costs and uncertainties associated with interest rate changes. We strive to effectively manage our interest rate risk by periodic monitoring and responding to risk factors on a timely basis, improve the structure of long-term and short-term borrowings and maintain the appropriate balance between loans with floating interest rates and fixed interest rates. We are subject to interest rate sensitivity on our outstanding 2027 Notes, 2029 Notes and 2030 Notes. We account for our convertible notes on an amortized cost basis and our recognized value of the convertible notes does not reflect changes in fair value. Also, because convertible notes we have issued either bear interest at a fixed rate or bear no interest, we have not incurred financial statement impact resulting from changes in interest rates. However, changes in market interest rates impact the fair value of the convertible notes along with other variables such as our credit spreads and the market price and volatility of our ADSs and ordinary shares. Increases in market interest rates would result in a decrease in the fair value of our outstanding convertible notes and decreases in market interest rates would result in an increase in the fair value of our outstanding convertible notes. For information on the maturities and other contractual terms of our convertible notes, see “Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Cash Flows and Working Capital.” With regard to interest rate sensitivity on our bank loans, we present the sensitivity analysis below based on the exposure to interest rates for interest bearing bank loans with variable interest rates as of December 31, 2025. The analysis is prepared assuming that those balances outstanding as of December 31, 2025 were outstanding for the whole financial year. A 1.0% increase or decrease which represents our management’s assessment of the reasonably possible change in interest rates is used. Assuming no change in the outstanding balance of our existing interest-bearing bank loans balances with floating interest rates as of December 31, 2025, a 1.0% increase or decrease in each applicable interest rate would add or deduct RMB0.3 million (US$0.0 million) to our interest expense for the year ended December 31, 2025. We have not used any derivative financial instruments to manage our interest risk exposure. In addition, we may from time to time invest in interest-earning instruments. Investments in both fixed rate and floating rate interest-earning instruments carry certain interest rate risk associated with our investment return. Fixed rate securities may have their fair market value adversely impacted due to a rise in interest rates, while floating rate securities may produce less income than expected if interest rates fall. ​
