Most Popular Narrative: 21.5% Undervalued

With Sanofi closing at €82.32 against a narrative fair value of about €104.87, the current price sits well below that implied level.

Sanofi's ongoing focus on innovative product launches and its strong R&D pipeline, highlighted by accelerating investments, multiple Phase III readouts through 2026, and continued expansion of biologics (e.g., Dupixent, amlitelimab), is viewed as positioning the company to capture higher demand for chronic disease treatments in a world with an aging population, which the narrative links to robust long-term sales growth and EPS upside.
