NVIDIA shareholders are suing the company and CEO Jensen Huang

A Nvidia shareholder has sued the company and chief executive Jensen Huang, alleging they misled investors about Huang’s relationship with Alice Huang, a former executive at Taiwanese firm Megaspeed who is suspected of working for Chinese intelligence. The case marks a potential courtroom response to allegations that have drawn scrutiny to Nvidia’s leadership and contributed to a sharp fall in its share price.

Mark Kistenmacher is seeking class action status for investors who bought Nvidia shares between 9 October, when a report described a connection between the pair, and 8 November, when Huang acknowledged an affair and Nvidia announced an investigation into whether he had been targeted by a foreign intelligence operation. The lawsuit challenges Nvidia’s earlier description of their contact as routine business meetings. Nvidia shares were on track to lose more than $470 billion in market value over two days.
