Gary Black Backs Rivian

Meanwhile, Rivian CEO RJ Scaringe said on the automaker's second-quarter earnings call that Chinese automakers will find it difficult to compete due to cost structure advantages and government support.

Rivian Begins E-Bike Deliveries

Rivian recently reportedly began delivering TM-B e-bikes manufactured by Also Inc., which was spun off from Rivian after months of delays and customer dissatisfaction. The spinoff previously achieved a $1 billion valuation through a $200 million funding round led by Greenoaks Capital.
