In the fourth quarter, the auto retailer reported an adjusted earnings per share of $5.76, surpassing the consensus estimate of $4.96. Additionally, revenue exceeded expectations due to a 55% increase in used vehicle sales. As a result, AutoNation shares rose 3% in premarket trading.

DoorDash experienced a 24.1% increase in premarket trading after reporting an optimistic outlook for the current quarter, despite seeing a 69% increase in revenue for 2021 as restaurants reopened for dine-in service.

Nvidia reported adjusted quarterly earnings of $1.32 per share, 10 cents above estimates. The graphics chip maker also reported better-than-expected revenue for the quarter and gave an upbeat outlook. However, the stock came under pressure on concerns about flat profit margins and its exposure to the cryptocurrency market. Despite this, Nvidia was down only 2.5% in premarket action.

Palantir's adjusted profit of 2 cents per share was half of what analysts predicted, although revenue exceeded forecasts.

Tripadvisor's unexpected quarterly loss and revenue that fell short of analyst forecasts caused it to tumble in the premarket.

Shares tumbled 7.9% in premarket trading.

Fastly's shares plummeted 31.9% in the premarket after the company gave lower-than-expected 2022 guidance. Despite reporting a narrower-than-expected fourth-quarter loss and revenue that came in above consensus estimates, Fastly's shares still suffered a significant decline.
