Rivian and Lucid have reported delivering far fewer cars than they've built this year.
Lucid reported that in the third quarter of this year, it built 2,282 cars but delivered just 1,393 of them to customers.
Rivian, too, has seen a gap, though less extreme: The Amazon-backed startup built 7,363 vehicles and delivered 6,584 in Q3.
For the first nine months of 2022, Rivian had produced 14,317 cars, and delivered 12,278, a rate of 86%.
Still, House said she expects vehicles produced to continue to outpace vehicles delivered in the near-term as Lucid accelerates production and starts delivering internationally.
