DUOL INVESTORS: Contact Kirby McInerney LLP About the Securities Fraud Lawsuit Filed on Behalf of Duolingo, Inc. Shareholders

  • Kirby McInerney LLP invites Duolingo investors who purchased securities between May 2, 2025, & February 26, 2026, to contact Lauren Molinaro by December 7, 2026, regarding a securities fraud class action.
  • The lawsuit alleges Duolingo concealed that deliberate user friction from increased ad volume, subscription upsells, & worsened product quality negatively impacted Daily Active User growth rates.
  • The complaint claims the Company's A/B testing showed that monetization pushes & low-quality AI content degraded the user experience & threatened financial sustainability.
  • On November 5, 2025, Duolingo reported a decline in DAU growth to 36% & announced a reversal of its monetization strategy, causing shares to drop 25.5% to $193.74.
  • On January 12, 2026, the resignation of CFO Matthew Skaruppa & a report of 30% DAU growth led to an 8.5% share price decline to $161.74.
  • On February 26, 2026, Duolingo confirmed DAU growth slowdowns & provided 2026 guidance projecting 20% growth & below-consensus revenue & earnings, resulting in a 14% share price drop to $101.00.
  • Investors are urged to contact the firm at no cost to discuss their rights, with lead plaintiff applications subject to strict court deadlines.
