The complaint asserts that\ninvestors suffered billions of dollars in losses. LEAD PLAINTIFF DEADLINE:\nDecember 7, 2026.\n\nTHE CASE: The Exchange Act action is pending in the U.S. District Court for\nthe Western District of Pennsylvania. It challenges whether Duolingo's\nshareholder letters, Forms 10-Q and earnings calls disclosed that ad-heavy\nmonetization, the Energy feature and mass-produced AI content were eroding\ndaily active user (\"DAU\") growth.\n\nDuolingo SEC Disclosure Adequacy: The Language Investors Received\n\nSEC filings stated, in Duolingo's second-quarter 2025 shareholder letter, that\nDAU growth reflected the Company's \"ability to continuously improve our app.\"\nThe letter also credited Energy with lifting DAUs, learning time and\nsubscriber conversion, adding: \"We have rarely seen a feature move more than\none of these metrics, let alone all three.\"\n\nOn the August 6, 2025 earnings call, management said it did not believe the AI\nbacklash was \"very material in terms of when you're looking at actual\nfinancial metrics.\" Management also explained that the Company \"typically only\nguide[s] to DAU whenever there's going to be a big change.\"\n\nDisclosure Gaps Alleged\n\nThe complaint challenges those statements as materially incomplete. It alleges\nthey omitted that:\n\n * Energy drained a free user's balance with each correct answer, a design\nplaintiffs say was aimed at forcing paid conversions\n * The Company's thousands of A/B tests showed added friction was depressing DAU\ngrowth rates\n * Unskippable ads after each lesson pushed some users to abandon years-long\nstreaks\n * Rapidly generated AI content brought translation errors, pronunciation errors\nand repetitive lessons, even in the premium Max tier\n * The DAU slowdown extended beyond the AI-memo backlash and was expected to\npersist alongside the monetization push\nWhy Generic Warnings May Not Protect\n\nPlaintiffs contend that cautionary language cannot shield statements about\nrisks allegedly already visible in the Company's own test data. Management\nagain declined to guide DAUs in November 2025, yet preliminary figures in\nJanuary 2026 put DAU growth at 30% and the February 26, 2026 results guided\n2026 growth to just 20%. According to the complaint, management then\nacknowledged deliberately introducing \"friction\" into the free user\nexperience.\n\n\"Generic risk factor language cannot substitute for disclosing specific, known\nproblems that are already affecting a company's operations. The complaint\nalleges Duolingo's internal testing showed monetization friction was slowing\nuser growth, despite management downplaying its impact. Shareholders deserve\nto know whether those disclosures matched what management allegedly knew.\" --\nJoseph E.
