Coca-Cola Femsa is trading at $103.45, down 4.85%, after-hours; no clear company-specific announcement explaining the September 28 drop was found.

  • Company press-release listings show its latest results were reported in July, not after the close.
  • Reuters reported U.S. stocks fell as oil prices and Treasury yields remained elevated amid uncertainty over U.S.-Iran talks. Broader market weakness may have contributed, but available evidence does not establish the direct cause of this after-hours move.
