Embraer is trading at $64.56, down 12.04%, with no verified November 2 announcement or company-specific catalyst explaining the sharp pre-market decline.

  • Embraer announced an ADS ratio change on October 30, scheduled for November 16, and said it does not change holders’ economic ownership value.
  • The Q3 earnings preview is not a reported result; Embraer’s investor calendar lists its Q3 release for November 10.
  • U.S. futures were higher, so broad-market weakness does not explain the drop.
