Oddity Tech Investors Face Monday Deadline To Seek Lead Role in Securities Case

The case hinges on claims that an ad-platform algorithm change inflated marketing costs.

Overview

  • Investors who bought ODDITY Tech shares from Feb. 26, 2025 to Feb. 24, 2026 have until Monday to ask a court to serve as lead plaintiff.
  • Rosen Law and Hagens Berman are urging ODD shareholders to file now as they compete to represent the putative class.
  • The complaints say Oddity’s largest advertising partner changed its algorithm, sending ads into lower-quality auctions at higher prices and driving up customer acquisition costs.
  • After Oddity disclosed the ad account “dislocation” on Feb. 25, 2026, the company projected a 30% year-over-year revenue decline for Q1 and the stock fell about 49% to $14.74.
  • A class action is on file but no class is certified, so investors are not represented unless they retain counsel, and a lead plaintiff can help steer strategy and settlement talks.
