Rivian Loses Its Shine as Investors Fret About Production Delays

The company also did not tell investors that its chief operating officer, Rod Copes, a Harley-Davidson veteran, left the company last year. Public companies and those in the process of listing their shares generally disclose the departures of top executives. The news was first reported by The Wall Street Journal.

Ms. Mast said Mr. Copes had a “phased transition from Rivian in fall 2021, prior to the I.P.O.,” and retired in December, after the offering.

Mr. Copes, 55, said in an interview that he did not leave Rivian because of concerns about his performance or because there were problems with production. He said that he had achieved key goals and that the structures were in place for Rivian’s ramp-up in production. “It was a smooth and seamless transition,” Mr. Copes said.

But corporate governance experts think Rivian ought to have disclosed his impending departure to investors during the I.P.O., given his senior role. “If they knew he was leaving, the optimal disclosure would have been to identify their C.O.O. but indicate that he was leaving,” John C. Coffee Jr., a professor at Columbia Law School, said in an email.

According to one former executive, Rivian has a poor management culture.

The executive, Laura Schwab, said she was fired last year from a high-ranking sales and marketing position after expressing concerns about what she called the “boys’ club culture” and “gender discrimination” at the company. She filed a lawsuit in state court in California accusing Rivian of violating the state law prohibiting employment discrimination and retaliation.

Ms. Schwab said she had been part of 30 vehicle introductions in prior automóvil industry jobs, including at Aston Martin and Jaguar Land Rover. Soon after arriving at Rivian, she said, she felt compelled to express concerns that the company was in danger of missing delivery targets.

“The production line doesn’t go from zero to thousands of cars overnight; it just doesn’t work that way,” she said.
