Serve Robotics Stock Jumps 39% After Q3 Results Raise Full-Year Revenue Guidance to $12 Million

Serve Robotics (Nasdaq: SERV) jumped 38.8% on Friday, Nov. 6, 2026, closing at $3.22 from a previous close of $2.32, after the company reported third-quarter results and raised its full-year revenue outlook. The S&P 500 ETF (SPY) rose 0.31% over the same session, and volume ran at about three times its normal level.

The catalyst was an 8-K filed after the close on Nov. 5, which furnished the third-quarter press release and a revised investor presentation. The release reported revenue of $2.8 million, up 313% from a year earlier, and said full-year 2026 revenue guidance rose to $12 million from the previous range of $9 million to $10 million.

Guidance raised, costs trimmed

The company also lowered its full-year 2026 non-GAAP operating expense guidance to $150 million, down from $160 million to $170 million given at the start of the year. Management said the launch of Serve Physical AI Services would make the technology behind its fleets available to other robot makers.

Cash and losses

Serve ended the quarter with $198.0 million in cash and investments together, of which $50.8 million was cash and equivalents and $147.2 million was short-term marketable securities. The company's third-quarter net loss was $59.2 million, wider than the $33.0 million loss a year earlier.

A 10-Q filed later the same day repeated the quarterly figures.
