Nikola CEO Lohscheller steps down, board chairman Girsky named new CEO amid growing losses

Nikola CEO Michael Lohscheller is resigning due to a family health matter and will be replaced by board chairman Steve Girsky.
Nikola reported a narrower second-quarter loss but lower production of its electric trucks.
Lohscheller will stay on in an advisory role until September before returning to Europe.
Girsky becomes the fourth CEO for Nikola in recent years as the company faces scandals and scaled-back ambitions.
Nikola has started production of its hydrogen fuel cell truck but growing losses caused its stock price to fall after the announcement.
