Nikola Corp's stock is trading lower by 4.6% despite no company-specific news. This may be due to the disappointing sales results reported last week, primarily due to a lack of truck production and only 3 truck shipments in the quarter. The company posted a large gross loss of $125.5 million, expanded EBITDA loss of $188.6 million, and an adjusted EPS loss of 30 cents, missing consensus estimates. Nikola also anticipates increased expenses due to a truck recall.
