Confirmed holdings include full ownership of ImCheck Therapeutics, Albireo and Epizyme, plus a 7.4% position in Sutro Biopharma. Capital is deployed via Ipsen Ventures and direct acquisitions. Geographic reach covers France, the United States and Luxembourg. Ipsen operates from its headquarters in Boulogne-Billancourt and maintains additional facilities including the Dreux and L'Isle-sur-la-Sorgue manufacturing plants. The company sponsors the Fondation Ipsen and the Alasol Foundation. May 2025: Ipsen held its Annual General Meeting in Paris.
