On the evening of September 21, Zhenlei Technology made a public announcement revealing that its actual controller and chairman, Yu Faxin, had been taken into custody by the Huangshi Municipal Supervisory Committee. Trading data indicates that on the 22nd, during the call auction phase, Zhenlei Technology's shares opened at a significantly lower price and continued their downward trajectory after the market opened. Despite a partial recovery during the trading session, by the market's close, the share price had settled at 60.77 yuan, marking a 12.56% decline. The share price experienced a modest rebound on the 23rd. This company, previously lauded as a 'rising star in the realm of special-purpose chips' due to its staggering net profit increase of over tenfold in the first half of the year, has now ignited widespread apprehension regarding underlying issues such as governance risks, business reliance, and the sustainability of its remarkable performance.
