  • It closed at $17.89 on September 8.
  • September 8 conference commentary highlighted evolving SMS pricing, possible margin impact, and early monetization of Customer Agent and Composer; available coverage does not explicitly attribute the decline to those remarks.
  • Broader indices are only modestly lower, and no confirmed specific catalyst has been identified.
