Ex-Rivian Executive’s Discrimination Suit Airs Questions About Business Plans as IPO Looms

A former sales and marketing vice president at Rivian Automotive Inc. has sued the electric-vehicle startup, alleging that she was fired last month after telling a human-resources executive that she had been subjected to gender discrimination.

The complaint, filed Thursday ahead of Rivian’s hotly anticipated initial public offering, details concerns she allegedly raised internally, including that the company underpriced its vehicles, had manufacturing-quality issues and set unrealistic delivery targets.
