Comparison to Industry Standards

• The acquisition price of up to $600 million is comparable to other deals in the neurodegenerative disease space, reflecting the high value placed on promising clinical-stage assets.
• The use of a CVR is a common mechanism in pharmaceutical acquisitions to share the risk and reward associated with the development of a clinical candidate.
• The focus on TREM2 agonists aligns with the broader industry trend of targeting immune pathways to treat neurodegenerative diseases.
• Other companies working on TREM2-targeting therapies include Alector, Denali Therapeutics, and Biogen, making Vigil a valuable addition to Sanofi's portfolio.

Stakeholder Impact
