Oddity Tech's shares fell about 7% in premarket trading on Thursday after two major brokerages lowered their ratings following the company's guidance for a roughly 30% year-over-year sales decline in the first quarter. Banks flagged that an algorithm change at the firm's largest advertising partner - which contributes about 25% of revenue - cut visibility for its try-before-you-buy offer, driving up acquisition costs and reducing repeat purchases.

Key Points

  • Oddity Tech forecast a roughly 30% year-over-year sales decline for Q1, a sharp reversal from prior 20%+ growth trends - impacts digital advertising and consumer-facing retail sectors.
  • Barclays cut its rating to Underweight and JPMorgan downgraded to Neutral from Overweight after the company attributed the decline to an algorithm change at its largest ad partner, which accounts for about 25% of revenue.
  • The ad-partner change reduced visibility for Oddity's try-before-you-buy program, increasing customer acquisition costs and lowering traffic quality across brands including IL MAKIAGE, SpoiledChild and MethodIQ - relevant for marketing and e-commerce performance metrics.

Market reaction and guidance

Shares of Oddity Tech dropped roughly 7% in premarket trading on Thursday after the company issued guidance showing a steep break from recent trends. Management now expects sales in the first quarter to decline about 30% year over year, reversing a prior growth trajectory that had seen the business expand at more than 20% annually.

Analyst moves

Barclays reduced its recommendation to Underweight, warning that the deterioration could indicate deeper, emerging problems for the company. The bank pointed to the guidance as evidence the business remains heavily dependent on paid digital customer acquisition rather than more durable, organic demand drivers.

JPMorgan Chase also lowered its view on the stock, moving to Neutral from Overweight. The firm described Oddity's first-quarter outlook as "a shock" after the company had produced 11 consecutive quarters of revenue beats and raised outlooks prior to this update.

Catalyst: ad algorithm change

Oddity reported that its largest advertising partner, which represents roughly 25% of company revenue, modified its algorithm in a manner that reduced the platform visibility for the company's "try before you buy" program. Under that initiative, customers pay only for shipping on their first order - a tactic that historically lifts conversion but can increase product returns. The company reported return rates of about 11% in 2024.

The algorithm adjustment led to lower-quality traffic and, in some instances, more than doubled customer acquisition costs across several of Oddity's brands, including IL MAKIAGE, SpoiledChild and MethodIQ. Management identified the problem in late January, and as of the update the issue had not been resolved.

Analyst caution and potential recovery

JPMorgan cautioned that there is limited visibility regarding the timing and magnitude of any recovery. The bank warned that financial results may be pressured for multiple quarters, even under a best-case scenario, owing to a loss of repeat revenue. Still, the firm noted the disruption appears isolated to Oddity and may be remediable over time.

Barclays emphasized that the episode highlights how much of Oddity's growth has been driven by direct response marketing, rather than traditional beauty market dynamics such as word of mouth or product-led loyalty.

Investor tools and screening

Separately, a product called ProPicks AI is noted for evaluating stocks like ODD across a broad set of financial metrics each month. The tool is described as assessing fundamentals, momentum and valuation without bias, and has highlighted past winners including Super Micro Computer (+185%) and AppLovin (+157%).


This report focuses on the company update, market reaction and analyst commentary provided in the company's guidance and brokerage notes.

Risks

  • Limited visibility on timing and magnitude of recovery - JPMorgan warns results could be pressured for multiple quarters, affecting investor expectations and near-term earnings in consumer discretionary and tech-driven retail companies.
  • Heavy reliance on paid digital acquisition rather than organic brand demand or product-driven loyalty, which increases vulnerability to third-party ad algorithm shifts and raises marketing cost volatility for Oddity and similar direct-to-consumer businesses.
  • Elevated return rates tied to the try-before-you-buy program - reported returns of about 11% in 2024 imply margin and inventory risks if acquisition costs remain high and conversion quality is reduced.
