How it happened
Sono Motors, a German EV startup, developed the solar-paneled Sion car and IPO'd on Nasdaq in November 2021 at roughly a $1.5B valuation. Unable to raise enough funding to mass-produce the Sion, it killed the consumer car program in early 2023 to focus on solar technology for third parties. Its market cap fell well below $1B, about 90% off peak.
