Cruise LLC, the autonomous-vehicle startup majority owned by
General Motors Co., said Chief Executive Officer Dan Ammann is leaving the company, just as it’s on the verge of starting a commercial service with self-driving cars.
GM
gave no reason for the departure of Ammann, who was president of the Detroit-based automaker before taking over the startup in 2019. GM’s stock extended declines, falling 2.7% to $56.80 in postmarket trading after slipping less than 1% during the regular session.
