Thesis Summary

Sanofi entered the second half of 2026 with strong operating momentum: Q2 sales rose 17.8% at CER, business EPS rose 33.3% at CER and management upgraded full-year sales-growth guidance to around 10% at CER. Dupixent and newer pharmaceutical launches provide substantial growth, while recent approvals and regulatory submissions broaden the opportunity set. The balance is less compelling because growth remains heavily dependent on Dupixent, vaccines declined in Q2 and management stopped or deprioritized several clinical programs.

Bear CaseDownside scenario
$45.0018%

Second-half growth normalizes more sharply than management expects, vaccine weakness persists and Dupixent growth slows before newer launches become sufficiently material. Additional pipeline failures or regulatory setbacks would increase dependence on existing products and undermine confidence in the accelerated transformation.

Base CaseCentral scenario
$53.7258%
Matches the consensus mean

Sales grow around the upgraded 2026 guidance of 10% at CER and business EPS grows slightly faster, with Dupixent and pharmaceutical launches offsetting softer vaccines and pipeline-prioritization costs. Pipeline approvals continue, but recent program discontinuations keep execution risk elevated.

Bull CaseUpside scenario
$63.0024%

Sanofi exceeds its upgraded 2026 guidance as Dupixent sustains strong growth, acquired and internally developed launches scale, and upcoming regulatory decisions add commercial opportunities. Continued execution toward management's 2030 ambitions for Dupixent and pharmaceutical launches would improve diversification and reinforce profitable growth.

Scenarios are anchored to street consensus at the research date, with our probabilities and rationale.
