Pfizer Files Second Lawsuit to Block Novo Nordisk’s $9bn Metsera Bid

Pfizer alleges Novo Nordisk’s $6 billion bid to acquire Metsera is anticompetitive and aims to block the deal under the Clayton Antitrust Act, citing risks to market competition.

  • On Monday, Pfizer filed a second lawsuit in Delaware alleging Novo Nordisk's $9 billion outbid is anticompetitive and accusing Metsera's controlling shareholders of conspiring with both companies.
  • After struggling to launch its own obesity products, Pfizer targeted Metsera to acquire two late-stage candidates and agreed in September to pay $4.9 billion, rising to $7.3 billion with future payments.
  • Metsera's pipeline includes a GLP‑1 agonist and an amylin analogue ready for phase 3 that could enable once‑monthly dosing versus weekly rivals, with analysts estimating peak annual sales of $5 billion or more.
  • Metsera said `Pfizer is trying to litigate its way to buying Metsera for a lower price than Novo Nordisk` and said it will address the filings in court.
  • Pfizer alleges the bid would protect Novo Nordisk's dominant GLP‑1 position by sidelining a U.S. rival, warning it would harm millions of Americans with obesity, diabetes, and metabolic conditions.
