Shares of SUV maker Fisker and truck maker Nikola Corp (NKLA.O), which reported early on Tuesday, fell 7% and 13%, respectively.
Shares of Lucid, which makes luxury sedans, dropped 6% on Tuesday after its results late on Monday.
Fisker lowered its annual production target to between 32,000 and 36,000 vehicles from its earlier target of 42,400 cars, blaming supply-chain issues and an "updated timing" for roadworthiness certification.
The company, which started production of its Ocean SUV just in November and has $652.5 million in cash, also posted a larger-than-expected loss.
For Nikola, cash burn came in at $240 million as it produced 63 vehicles.
