Pfizer Secures Deal to Acquire Obesity Drug Developer Metsera, Outbidding Novo Nordisk
U.S. pharmaceutical giant Pfizer has emerged victorious in a high-stakes bidding war against Danish drugmaker Novo Nordisk for New York-based Metsera Inc., a development-stage company focused on obesity treatments.
The agreement, announced Friday, values Metsera at up to $86.25 per share, with Pfizer offering $65.60 per share in cash upfront plus a contingent value right that could provide shareholders additional payments of up to $20.65 per share if certain milestones are achieved. The total deal could be worth billions, significantly higher than Pfizer’s initial September offer of approximately $4.9 billion.
Metsera, which currently has no products on the market, is developing both oral and injectable treatments targeting the lucrative obesity and diabetes sectors. These therapeutic areas have seen explosive growth in recent years, with obesity drugs alone projected to become a $100 billion market by 2030, according to industry analysts.
The acquisition represents a strategic pivot for Pfizer, which has been seeking to establish a foothold in the weight loss drug market after recently abandoning development of its own obesity pill treatment. The pharmaceutical giant is looking to diversify its portfolio beyond COVID-19 vaccines and treatments, which have seen declining demand.
Metsera’s board cited potential U.S. antitrust concerns with Novo Nordisk’s competing offer as a key factor in their decision. “The board has determined Pfizer’s revised terms represent the best transaction for shareholders, both from the perspective of value and certainty of closing,” the company stated.
The bidding war intensified earlier this week when Novo Nordisk, maker of the wildly successful weight loss treatments Ozempic and Wegovy, increased its offer to up to $10 billion on Tuesday. That proposal included $62.20 in cash per Metsera share plus a contingent value right payment of $24 if certain development and regulatory milestones were met. The enhanced bid came after Pfizer filed a lawsuit challenging Novo’s previous offer of up to $9 billion.
Following Metsera’s acceptance of Pfizer’s proposal, Novo Nordisk announced Saturday it would not increase its offer further and was withdrawing from the acquisition race. The Danish company has dominated the weight loss drug market with Wegovy and diabetes treatment Ozempic, both containing the active ingredient semaglutide, which has shown remarkable efficacy in reducing body weight.
The competition for Metsera underscores the pharmaceutical industry’s aggressive push into the obesity treatment space, which has been transformed by the success of GLP-1 receptor agonists like those produced by Novo Nordisk and Eli Lilly’s Mounjaro and Zepbound.
Pfizer expects to finalize the transaction shortly after Metsera’s shareholder meeting scheduled for November 13, pending approval from Metsera shareholders and regulatory authorities.
Industry analysts view the acquisition as potentially transformative for Pfizer, which has been seeking new growth drivers as revenue from its COVID-19 products wanes. The company’s stock has struggled in recent months amid concerns about its post-pandemic growth strategy.
For patients and healthcare providers, the increased competition in obesity treatments could eventually lead to more therapeutic options and potentially more affordable alternatives to current medications, many of which remain expensive and are often not covered by insurance.
The obesity drug market has attracted significant investment as the global obesity epidemic continues to grow, with more than 40% of U.S. adults classified as obese. Current treatments have demonstrated not only weight loss benefits but also improvements in cardiovascular outcomes, further driving demand and expanding the potential market.
