Cyborg Score Rationale
IO Biotech demonstrates strong scientific credentials and innovative technology platform, evidenced by Phase 3 data and Fast Company recognition. However, significant clinical trial setback (Phase 3 missed primary endpoint), severe stock depreciation (down 88% from 52-week high of $2.79 to $0.32), minimal market cap ($23-26M), and recent workforce reduction in January 2026 reflect substantial execution challenges and financial stress.
