Sanofi SAStock may be undervalued with P/E below industry average and modelled fair P/E, and fresh drug approvals support future cash flows

Sanofi's stock may be undervalued following recent drug approvals, with its price-to-earnings ratio of 18.7 times sitting below the pharmaceutical industry average of 20.7 times and a modelled fair P/E of 34.2 times. The company has secured approvals for therapies including Wayrilz, Cenrifki and Tzield, which could support future cash flows, though an ongoing European Commission antitrust probe into flu vaccine marketing presents regulatory risk. A bull case sees the stock as 22% undervalued, citing a strong pipeline with multiple Phase III readouts through 2026 and expansion of biologics like Dupixent, while a bear case flags heavy reliance on Dupixent, which generated €15.7 billion in annual sales, as a concentration risk. The stock has declined around 11.8% over the past three years, and the key question is whether the current discount reflects genuine upside or well-founded caution.
