Appian is trading 12.68% down at $29.90 after investors reacted negatively to cautious comments during the September 9, 2026 Citi Global TMT Conference.

  • Management said some customers are still deciding whether they need specific AI tools, raising concerns about near-term demand.
  • Stronger growth commentary, improved margin guidance, and a $100 million buyback authorization provided positive developments.
  • Broader technology weakness and elevated rate concerns may have added pressure.
