Recent Developments

The following sets forth certain unaudited consolidated statements of operations data for the three months ended March 31, 2018. On January 1, 2018, we adopted the new revenue standard ASC 606 using the modified retrospective method. The adoption of ASC 606 did not have any material impact on our consolidated financial statements. In addition, we have prepared these unaudited consolidated statements of operations data on the same basis as our audited consolidated financial statements. These unaudited consolidated statements of operations data reflect all adjustments, consisting only of normal and recurring adjustments, which we consider necessary for a fair statement of our results of operations for the period presented. We cannot assure you that our results for the three months ended March 31, 2018 will be indicative of our financial results for the full year ending December 31, 2018 or for future periods. Please refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors” included elsewhere in this prospectus for information regarding trends and other factors that may affect our results of operations.

Our live streaming revenue increased by 107.2% mainly due to the increase in the number of our paying users on our platform and increase in the spending per paying user. Our advertising and other revenues increased by 212.4% as we continue to expand our advertising services business that we began to offer in October 2016.

• Our costs of revenues increased by 86.2% from RMB382.8 million for the three months ended March 31, 2017 to RMB712.5 million (US$113.6 million) for the three months ended March 31, 2018, primarily contributed by increase in revenue sharing fees and content costs, bandwidth costs, salaries and welfare due to business expansion.

• Our research and development expenses increased by 21.4% from RMB42.4 million for the three months ended March 31, 2017 to RMB51.5 million (US$8.2 million) for the three months ended March 31, 2018, mainly contributed by increase in the salaries and welfare of research and development personnel. Our sales and marketing expenses increased by 70.3% from RMB15.2 million for the three months ended March 31, 2017 to RMB25.9 million (US$4.1 million) for the three months ended March 31, 2018, mainly contributed by the increase of marketing and promotion expenses due to business expansion. Our general and administrative expenses increased by 251.2% from RMB10.2 million for the three months ended March 31, 2017 to RMB35.8 million (US$5.7 million) for the three months ended March 31, 2018, mainly contributed by the increase of share-based compensation as well as salaries and welfare of management personnel.

• As a result of the above, our operating income for the three months ended March 31, 2018 was RMB28.2 million (US$4.5 million), including the effect of RMB24.4 million (US$3.9 million) in share-based compensation expenses, as compared to an operating loss of RMB42.2 million for the three months ended March 31, 2017, including the effect of RMB7.0 million in share-based compensation expenses.
