Novo Nordisk and Pfizer’s bidding war for Metsera escalates despite legal threats

Novo Nordisk and Pfizer Escalate Bidding War for Metsera

Both Novo Nordisk and Pfizer have increased their offers to acquire obesity biotech Metsera, with Novo Nordisk now leading with an additional $1.9 billion.

Raised Offer by Novo Nordisk

Novo Nordisk recently raised its bid for Metsera to $10 billion, up from the initial unsolicited offer of $8.5 billion made just last week. This move intensified competition as Pfizer's earlier $7.3 billion offer had seemed likely to succeed.

Details of Novo Nordisk's Proposal

Metsera’s board of directors has described the $10 billion offer as “superior.”

Pfizer's Response

Pfizer disputes this characterization, arguing that Novo Nordisk’s offer “cannot qualify as superior” due to the high “regulatory risk,” which they believe makes the transaction unlikely to be completed.

Pfizer states that the regulatory challenges associated with Novo Nordisk’s bid cast doubt on its feasibility.
Summary

The bidding war between Novo Nordisk and Pfizer for Metsera highlights strategic moves and regulatory concerns shaping the future of obesity biotech acquisitions.
