Jiamei Packaging's stock price drops, Yu Hao's phone is turned off.

On June 5, Jiamei Packaging closed at 16.79 yuan per share, a decrease of 9.97%. The company's stock resumed trading after the announcement of a change in controlling interest, opening with a 7% increase but closing with a limit-down. The company announced the completion of the full settlement and transfer of shares for a partial tender offer initiated by Suzhou Zhuyue Hongzhi Technology Development Partnership Enterprise, increasing their stake to 45.01% and officially becoming the company's controlling shareholder. Zhuyue Hongzhi was established in September 2025, with the actual controller being the founder of ZuiMi Technology, Yu Hao. Today, Yu Hao's Weibo account shows as being banned. Market rumors suggest that a certain district is requiring a tally of cooperation between companies in the district and ZuiMi Technology, including but not limited to: cooperative projects, overall scale, investment amount, financial and state-owned investment situations, and current operational status. Local officials responded to media inquiries by stating that there were no relevant situations in their area after the initial investigation. Calls to Yu Hao's phone were met with a turned-off message; ZuiMi's public relations personnel did not respond to inquiries; and the Industry Division of the Development and Reform Commission of Changzhou City responded that they were not aware of the situation mentioned in the online reports.
