More on SUPN's Acquisition Deal With SAGE
The potential acquisition would provide SUPN rights to SAGE’s new depression drug, Zurzuvae (zuranolone), the first and only oral treatment indicated for adults with postpartum depression (PPD). The drug was approved in August 2023 and commercially launched in December 2023.
SAGE markets Zurzuvae in partnership with drug giant Biogen (BIIB - Free Report) .
Sage Therapeutics and Biogen equally share profits and losses for the commercialization of Zurzuvae in the United States. In ex-U.S. markets, Biogen records product sales (excluding Japan, Taiwan and South Korea, where Shionogi holds the rights) and pays royalties to SAGE.
Following the latest turn of events, Supernus will recognize collaboration revenues that are 50% of Biogen’s U.S. net sales of Zurzuvae.
SAGE’s collaboration revenues from the sale of Zurzuvae were $13.8 million in the first quarter of 2025 and $36.1 million in 2024. The initial uptake of Zurzuvae has exceeded expectations.
The acquisition of Sage Therapeutics is likely to complement Supernus' diverse neuroscience portfolio, which includes approved treatments for attention-deficit hyperactivity disorder, dyskinesia in Parkinson’s disease, epilepsy and other central nervous system disorders.
SUPN expects the deal to be significantly accretive in 2026 and to further diversify its revenue base.
SAGE Previously Rejected BIIB's Offer
Sage Therapeutics previously rejected a takeover proposal from Biogen to acquire the remaining shares of SAGE in January 2025.
Per Sage Therapeutics, the offer significantly undervalued the company and was not in the best interest of shareholders.
Biogen made an acquisition offer to buy the remaining shares of SAGE that it did not already own for $7.22 per share in January. The offer price represented a premium of 30% on Sage Therapeutics’ closing price of $5.55 on Jan. 10.
Per a SEC filing by the company, Biogen owns a 10.2% stake in SAGE.
It can be inferred that Supernus has outbid Biogen to acquire Sage Therapeutics.
