Sivers Semiconductors is trading at €2.42, down -3.04%, with no clear company-specific catalyst identified for the September 7, 2026 decline.

  • On September 3, Sivers Semiconductors announced a USD 30 million Glasgow expansion targeting more than 100 million annual CW DFB lasers for AI datacenters and optical networks.
  • The announcement was positive but does not directly explain today’s decline; broader indices are flat, leaving the move’s cause uncertain.
