Oddity Tech Investment Narrative Recap

To own Oddity Tech, you need to believe its AI driven, digital first model can keep attracting and retaining beauty and wellness customers efficiently, even as it expands new brands and geographies. The new class action lawsuits around advertising cost disclosures go straight to today’s key issue: whether higher customer acquisition costs and reliance on a single major ad platform meaningfully weaken the near term growth catalyst and deepen the central risk to margins.

Oddity Tech's narrative projects $906.6 million revenue and $82.7 million earnings by 2029. This requires 3.8% yearly revenue growth and a $28.0 million earnings decrease from $110.7 million today.

Uncover how Oddity Tech's forecasts yield a $17.33 fair value, a 18% upside to its current price.
