Bill.com is trading at $37.00, down 20.41% after-hours, with no credible same-day company-specific catalyst identified.

  • The decline is versus the regular-session close of $46.49 on September 22, 2026.
  • The latest identified earnings event was an August 19 report that exceeded expectations, making it unlikely to explain the drop.
  • Volume details were unavailable, so confidence is low.
