Serve Robotics is trading 8.54% down at $5.17 after management cut 2026 revenue guidance to $9 million–$10 million from $26 million, citing weaker-than-expected Uber Eats delivery volumes and removed second-half demand.
- Second-quarter revenue reached $3.24 million but missed expectations by approximately $0.68 million.
- The guidance reduction overshadowed 404% year-over-year growth and is the clear catalyst for the decline.
