Pfizer Announces $7.3 Billion Acquisition of Metsera
Pfizer has entered into an agreement to acquire Metsera, a biotech company specializing in weight loss drugs, in a deal valued at up to $7.3 billion. The transaction includes an upfront cash payment and contingent future payments tied to clinical and regulatory milestones. The initial offer stands at $47.50 per share in cash, representing a nearly 43% premium over Metsera’s closing price of $33.32 last Friday. This translates to an enterprise value of approximately $4.9 billion, with the potential total rising to $70 per share if all milestone targets are met. The deal is expected to finalize by the end of 2025. Following the announcement, Metsera’s shares surged over 60% in premarket trading, while Pfizer’s stock increased by more than 1%.Strategic Rationale Behind the Acquisition
Pfizer’s acquisition of Metsera comes after several challenges in its obesity drug development pipeline. Earlier efforts, including the lead candidate danuglipron, were discontinued due to safety concerns, and another oral drug was halted amid adverse liver enzyme effects. Despite these setbacks, Pfizer maintains a pipeline of early-stage obesity treatments with diverse mechanisms. The company faces increasing pressure from investors to accelerate its entry into the rapidly growing obesity market, which analysts estimate could reach $100 billion by the 2030s. Metsera’s portfolio offers Pfizer a strategic advantage, featuring both oral and injectable therapies with novel targets. This acquisition aligns with Pfizer’s goal to leverage its cardiometabolic expertise and commercial infrastructure to capture significant market share.Metsera’s Innovative Pipeline
Founded in 2022, Metsera has rapidly developed a promising pipeline of obesity treatments. Its lead candidate, MET-233i, is a GLP-1 receptor agonist that demonstrated weight loss of up to 8.4% in 36 days during early-stage trials. Notably, MET-233i is designed as a once-monthly injectable, offering a more convenient dosing schedule compared to existing weekly injections from competitors. In addition, Metsera is developing a monthly treatment targeting the hormone amylin and has two oral GLP-1 candidates slated to begin clinical trials imminently.Market Opportunity and Analyst Perspectives
The obesity drug market is expanding rapidly, driven by increasing demand for effective weight loss therapies. Analysts forecast this segment could be worth nearly $100 billion within the next decade. Leerink Partners analyst David Risinger estimates Metsera’s obesity candidates could achieve combined peak annual sales exceeding $5 billion. JPMorgan analyst Chris Schott highlighted that Metsera’s experimental drugs are expected to accelerate Pfizer’s entry into this competitive space. Metsera’s recent IPO in 2025 was among the largest biotech listings this year, underscoring strong investor interest in next-generation obesity treatments amid competition from established players like Eli Lilly and Novo Nordisk.Pfizer CEO Comments on the Acquisition
“The proposed acquisition of Metsera aligns with our focus on directing our investments to the most impactful opportunities and propels Pfizer into this key therapeutic area,” said Pfizer CEO Albert Bourla. “We are excited to apply our deep cardiometabolic experience and manufacturing and commercial infrastructure to accelerate a portfolio that includes potential best-in-class injectables.”FinOracleAI — Market View
