Sivers Semiconductors is trading 4.6% down now at €3.58, with no clearly dated catalyst identified for the August 18, 2026 decline.

  • August 13: SemiNex AI-data-center development program worth approximately $3.4 million.
  • August 17: intention to separate Sivers Photonics through a proposed merger.
  • Neither event explicitly links to the decline; semiconductor sentiment was broadly positive, making sector weakness unlikely.
