On September 29th, Kirin Capital purchased 820,000 shares of CSI, following their acquisition of 1.5 million CSI shares on September 18th. Within a span of approximately 10 days, Kirin Capital amassed 2.32 million CSI shares, increasing their holdings from over 1.7 million shares (10.26%) to more than 4 million shares (24.07%).

Notably, Kirin Capital wasn’t the only entity making significant moves in CSI shares during this period. Two key CSI executives also announced substantial transactions.

Specifically, Vice Chairman and CEO Mr. Hoàng Xuân Hùng registered to purchase 2 million shares, boosting his holdings to over 2.8 million shares (16.8%). Conversely, Chinese board member Mr. Li You Mu registered to sell his entire stake of 4.32 million shares (25.71%) during the same September 17th – October 15th period via negotiated transactions.

Intriguingly, the combined total of Mr. Hoàng Xuân Hùng‘s registered purchase and Kirin Capital’s recent acquisitions equals 4.32 million shares, matching Mr. Li You Mu‘s registered sale. This suggests a potential capital transfer between these parties.

Mr. Li You Mu already sold 1.5 million shares on September 18th, while Mr. Hoàng Xuân Hùng acquired nearly 1.5 million shares on September 24th, becoming a major shareholder.
