Lordstown Motors went public on the Nasdaq in late October via a combination with a special-purpose-acquisition-company, or SPAC.
The company says that it expects to report earnings on a normal schedule, commencing with year-end results for 2020.
It was expected to receive about $675 million of gross proceeds from its initial public offering.
At the time, the company said it had 40,000 preorders for its flagship work pickup truck, which would account for $2 billion in revenue if every order was filled.
Lordstown expects operational-earnings margins to at least reach break-even in 2022, its first full year of production, and surpass 10% by 2024.
At last check Lordstown Motors shares were up 10% at $19.78. They've traded on Monday up as much as 13% at $20.23.
