SES is trading 4.11% down at €4.92, with no clear company-specific announcement identified for August 21, 2026.

  • SES’s latest official releases concern its August 17 collaboration with Elveo Mobile and August 7 IRIS² developments, rather than today’s decline.
  • The move follows continued weakness after July 30’s disappointing second-quarter revenue, though available reporting does not explicitly link that event to today’s decline.
  • Broader U.S. markets are higher, so global risk sentiment does not clearly explain SES’s drop.
