Oddity Investors Face May 11 Deadline to Seek Lead Role in Securities Suit

Overview

• Plaintiffs’ firms are urging Oddity shareholders to seek lead‑plaintiff status before the May 11, 2026 court deadline.
• The filed complaint targets investors who bought shares from February 26, 2025 through February 24, 2026.
• Filings allege Oddity’s largest ad partner changed its algorithm, pushing the company’s ads into lower‑quality auctions at unusually high prices and raising customer‑acquisition costs.
• The stock fell about 49% after Oddity warned that first‑quarter 2026 revenue would drop roughly 30% year over year, erasing more than $600 million in value.
• Hagens Berman says it is investigating when management first recognized the ad‑platform problem, while multiple firms outline that the court‑appointed lead plaintiff will guide strategy and potential settlement and are also seeking whistleblower tips.
