Pfizer (PFE) Clinches $10B Metsera Deal, Beating Novo Nordisk — What the Winning Bid Means for the Obesity-Drug Race (Nov. 8, 2025)
Pfizer Inc. has secured a definitive agreement to acquire weight‑loss biotech Metsera in a transaction valued at up to $10 billion, ending a high‑stakes bidding war with Novo Nordisk and positioning Pfizer squarely back in the fast‑growing obesity market. Metsera accepted Pfizer’s revised offer late Friday; Novo said today it would not raise its competing bid. Reuters Pfizer’s final, sweetened bid prevailed after a week of public twists that included legal skirmishes and regulatory warnings. Metsera said the legal and regulatory risks tied to Novo’s proposal—flagged by the FTC—were “unacceptably high,” tipping the board toward Pfizer’s revised agreement. Novo responded that it would not increase its offer further, effectively bowing out. Reuters+1
