The deal's design balances immediate investment with long-term performance incentives for the acquired assets.
Completion of the acquisition is anticipated in the third quarter of 2026, pending necessary regulatory approvals and other standard closing conditions. Upon closing, Biogen will take full responsibility for the development, manufacturing, and worldwide commercialization of RayThera's therapeutic candidates. This transition will integrate RayThera's innovative pipeline into Biogen's extensive global operations.
