 price for our ordinary shares would be negatively impacted. If we obtain independent securities or industry analyst coverage and if one or more of the analysts who covers us downgrades our ordinary shares, changes their opinion of our shares, or publishes inaccurate or unfavorable research about our business, the price of our ordinary shares would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our Class A ordinary shares could decrease and we could lose visibility in the financial markets, which could cause the price and trading volume of our ordinary shares to decline.
