GM expects economic growth in the U.S. and improving semiconductor supplies to increase U.S. total light industry sales from around 15 million in 2021 to around 16 million in 2022. “The key constraint for sales continues to be reduced inventory levels as a result of the semiconductor shortage. Those inventory levels are beginning to recover against a backdrop of strong fundamental demand conditions, with ample job openings, high household savings and low interest rates,” said Elaine Buckberg, GM chief economist.
