Nvidia's Jensen Huang steps down as CEO; CFO Colette Kress named interim CEO, all-hands set for six days later on Nov. 18

Nvidia announced Thursday that CEO Jensen Huang has resigned with immediate effect, and CFO Colette Kress has been named interim CEO. The company will not hold an all-hands meeting until Nov. 18, six days after the announcement. Communications experts told Fortune that this is too long to wait for a shaken workforce. The New York Times reported a second affair, involving executive Kimberly Powell; neither Nvidia nor Powell has publicly responded. Semafor, citing two government officials, reported that Nvidia may be involved in several Department of Justice investigations. These reported allegations and investigations have not been confirmed.
