Sanofi completes the acquisition of Vigil Neuroscience, Inc.
Paris, August 6, 2025. Sanofi announces the completion of its acquisition of Vigil Neuroscience, Inc. (https://www.sanofi.com/en/media-room/press-releases/2025/2025-05-21-23-15-31-3086232) ("Vigil"). This acquisition strengthens Sanofi's early-stage pipeline in neurology with VG-3927, a novel, oral, small-molecule TREM2 agonist, which will be evaluated in a phase 2 clinical study in patients with Alzheimer's disease. In addition, the acquisition of Vigil's preclinical pipeline will further strengthen Sanofi's research in various neurodegenerative diseases.
In June 2024, Sanofi made a $40 million strategic investment in Vigil that included the exclusive right of first negotiation for an exclusive license, grant, or transfer of rights to research, develop, manufacture, and commercialize VG-3927.
Under the terms of the acquisition agreement, Sanofi and Vigil have agreed to the following:
- Sanofi acquired all outstanding common shares of Vigil for $8 per share in cash at closing, representing an equity value of approximately $470 million (on a fully diluted basis)
- In addition, Vigil's shareholders received a non-transferrable contingent value right (CVR) per Vigil share, which entitles its holder to receive a deferred cash payment of $2, conditioned upon the first commercial sale of VG-3927.
VGL101, Vigil's second clinical program, was not acquired by Sanofi. As previously communicated, the acquisition of Vigil is not expected to impact Sanofi's financial guidance for 2025.
