THE LAWSUIT: A class action securities lawsuit was filed against Duolingo, Inc. that seeks to recover losses of shareholders who were adversely affected by alleged securities fraud between May 2, 2025 and February 26, 2026.

CASE DETAILS: The filed complaint alleges that defendants made false statements and/or concealed that: (a) DAU growth rates were being leveraged against deliberately added user friction in the form of significant increases in ad volume, subscription tier upsells, and worsened product quality, and defendants understood that any amount of user friction would cause users to leave the app and, ultimately, negatively impact DAU growth rates; (b) the Company's rigorous A/B testing demonstrated to Defendants that increased friction in the free user experience was having negative impacts on DAU growth rates; (c) the Company's quickly generated AI content was worsening the quality of Duolingo's product offerings, negatively impacting the user experience and user trends, and threatening the sustainability of the Company's financial performance; and (d) far from driving sustained growth and strong user momentum through content and "product improvements" that "get improved retention," the Company's constant A/B testing informed the Company that its monetization push and lower-quality, rapidly generated AI content were degrading the Duolingo product experience and the value proposition of its subscription tiers.
