**Comment for Reporting Person:** Row 1 -- Yuao Wu is also known as Michael Wu and was listed in the initial Schedule 13D (as defined below) as "Yuao Wu (Michael)".

Rows 8, 10 and 11 -- Immediately following the Share Distribution, AGL ceased to hold any Class A Ordinary Shares of the Issuer. The aggregate amount beneficially owned by Mr. Yuao Wu represents (i) 36,233,237 Class B Ordinary Shares held by Amber Fort Limited, (ii) 69,552,266 Class A Ordinary Shares received by Amber Fort Limited as a transferee in the Share Distribution, (iii) 19,458,931 Class A Ordinary Shares received by Amber Primary Unit Holding Limited as a transferee in the Share Distribution, and (iv) 6,698,479 Class A Ordinary Shares received by Digital Future Alliance Limited as a transferee in the Share Distribution. Each Class B Ordinary Share is convertible into one Class A Ordinary Share at any time at the option of the holder thereof. Each Class B Ordinary Share is entitled to 30 votes per share, and each Class A Ordinary Share is entitled to one vote per share. Mr. Wu is the sole director of each of Amber Fort Limited, Amber Primary Unit Holding Limited and Digital Future Alliance Limited and may be deemed to beneficially own the shares held by each such entity. Mr. Wu disclaims beneficial ownership of all such shares except to the extent of his pecuniary interest therein.
