Horizon Robotics is trading at HK$4.79 (-4.01%), with no clear company-specific announcement or event dated August 18, 2026 identified in available reliable coverage.

  • The latest HKEX filing surfaced was a July 31 monthly securities return, released August 6.
  • Earlier guidance projected stronger first-half revenue but a wider adjusted net loss; reported profit was largely tied to convertible-loan fair-value changes.
  • Semiconductor sentiment was positive, so sector weakness does not explain today’s decline.
