Multiple TECFIDERA generic entrants are now in North America, Brazil and certain E.U. countries and have deeply discounted prices compared to TECFIDERA.

LEQEMBI is in the early stages of commercial launch in the U.S. and certain international markets. In addition to risks associated with new product launches, Biogen's and Eisai's ability to successfully commercialize LEQEMBI may be adversely affected due to Eisai's ability to obtain and maintain adequate reimbursement for LEQEMBI.

The acquisition was funded through available cash on hand, indicating a conservative approach to capital structure.

In April 2024 we completed the sale of our rare pediatric disease PRV, generated by the development associated with SPINRAZA, to a third party.
