$ODD investors filed a claim against ODDITY Tech for allegedly hiding that an algorithm change at its largest advertising partner was pushing its ads into lower-quality auctions at unusually high costs.
After ODDITY Tech disclosed that this ad-auction disruption had sharply increased customer acquisition costs and said first-quarter 2026 revenue could decline about 30% year over year, $ODD fell 49.2% on February 25, 2026.
$ODD investors can join this case to be notified about potential recovery.
Case Details:

Between February 26, 2025 and February 24, 2026, ODDITY Tech told investors its direct-to-consumer model was strong, profitable, and built for sustained growth. Executives emphasized repeated revenue beats, raised guidance, strong margins, high repeat rates, and a digital model they said could keep delivering profitable growth.

However, during this period, investors allege ODDITY Tech was already being hurt by changes at its largest advertising partner that pushed its ads into lower-quality auctions at unusually high costs. ODDITY Tech allegedly failed to disclose that an algorithm change was worsening the quality of its ad placements; that those changes were significantly increasing customer acquisition costs; and that these rising costs were undermining the strength and sustainability of its digital operating model.

Then, on February 25, 2026, the company revealed a “dislocation” with its largest advertising partner, saying algorithm changes had diverted its ads to lower-quality auctions at unusually high costs and caused significant increases in new-user acquisition costs. $ODD fell $14.28, closing at $14.74. 

Additional revelations followed on February 25, 2026, including the company’s warning that first-quarter 2026 revenue was expected to decline about 30% year over year. By February 25, 2026, shares had dropped to $14.74, representing a total decline of 49.2% over the correction period.

Based on these events, $ODD investors filed a claim against ODDITY Tech, alleging the company:
It hid rising advertising costs tied to an algorithm change.
It portrayed its business model as stronger and more sustainable than it allegedly was while customer acquisition costs were climbing.
It caused investors to suffer losses when the company disclosed the ad-auction disruption and weaker outlook.
Investors argue ODDITY Tech misled the market about the stability of its digital advertising model and customer acquisition costs, causing losses when the truth emerged.
