Serve Robotics is trading 12.15% down at $4.99 following its August 6, 2026 earnings release and guidance cut to $9–$10 million.
- Second-quarter revenue reached $3.24 million, up 404% year over year but missing expectations; GAAP loss widened to $0.80 per share.
- Guidance fell from $26 million after weaker Uber Eats delivery volumes, pressuring sentiment; operating-expense and capital-spending targets fell to emphasize margins and cost discipline.
- The regular session closed at $5.68, making the extended-hours decline particularly significant.
