Metsera Acquisition

Metsera was acquired by Pfizer for $4.9B on 22 September 2025.

Before the acquisition Metsera had raised $505M across 2 funding rounds.

Metsera, a clinical-stage biopharmaceutical company developing next-generation oral and injectable incretin, non-incretin, and combination therapies for obesity and cardiometabolic diseases, including GLP-1 receptor agonist MET-097, long-acting amylin analog MET-233, and their combination MET-097i+MET-233i, was acquired by Pfizer. Pfizer, a global pharmaceutical giant, completed the acquisition on November 13, 2025, making Metsera a wholly owned subsidiary after its shares ceased trading on NASDAQ. The deal followed Pfizer's initial September 2025 agreement at $47.50 per share ($4.9 billion enterprise value), escalated by a bidding war with Novo Nordisk, which offered $6.5 billion but faced FTC antitrust concerns over its dominant obesity market position with Wegovy. Pfizer paid $65.60 per share upfront, valuing the enterprise at approximately $7.0 billion, plus a contingent value right (CVR) of up to $20.65 per share tied to three milestones: Phase 3 start of MET-097i+MET-233i combination ($5/share), FDA approval of monthly MET-097i monotherapy ($7/share), and FDA approval of monthly MET-097i+MET-233i combination ($10.50/share), for a potential total of $10 billion. The transaction, cleared by the FTC, positions Pfizer to lead in the high-growth obesity sector by complementing its internal medicine portfolio with Metsera's differentiated candidates, leveraging Pfizer's expertise in large-scale trials, manufacturing, and commercialization; CEO Albert Bourla noted therapies could reach market by 2028. The deal is expected to dilute earnings through 2030 due to investments in late-stage pipeline advancement amid competitive dynamics with established players like Novo.

DateStageInvestorsRaisedDeal Summary
Nov 2024Series BVenrock Healthcare Capital Partners (lead); Wellington Management (lead)$215MMetsera, Inc. is a clinical-stage biotechnology company developing next-generation therapies for obesity and metabolic diseases, with a portfolio including MET-097 and other peptide-based assets aimed at improving weight maintenance, muscle preservation, dosing frequency, efficacy, tolerability, and patient access beyond current leaders like Wegovy and Zepbound. The company launched in April 2024 with $290 million in Series A financing led by ARCH Venture Partners and others including F-Prime Capital, GV, Mubadala Capital, Newpath Partners, and SoftBank Vision Fund 2. In early January 2025, MET-097 showed 1.3% mean placebo-adjusted weight loss at 12 weeks in Phase II, leading to a successful Nasdaq IPO under MTSR, raising $255.8 million in net proceeds at $18 per share, with shares later rising significantly to over $73. Post-round, Metsera reported $352.4 million in cash, cash equivalents, and marketable securities as of December 31, 2024, up from $75.2 million in 2023, expected to fund operations into 2027 alongside IPO proceeds. The company later faced acquisition interest, culminating in Pfizer completing the purchase of Metsera and its portfolio, as announced by CEO Albert Bourla, amid competitive dynamics with rivals like Novo Nordisk.
Apr 2024Series AARCH Venture Partners (lead); Newpath Management; GV; SoftBank Group; F-Prime; Mubadala$290MMetsera, a New York-based clinical-stage biotech founded in 2022 by Population Health Partners and ARCH Venture Partners, emerged from stealth on April 18, 2024, with $290 million in seed and Series A financing led by ARCH Venture Partners. Participating investors included F-Prime Capital, GV, Mubadala Capital, Newpath Partners, SoftBank Vision Fund 2, and others. The funding supports development of a pipeline of oral and injectable therapies for obesity and metabolic diseases, including a GLP-1 receptor agonist in Phase I, a dual amylin/calcitonin receptor agonist, unimolecular GLP-1/GIP/glucagon combos, and an oral peptide delivery platform with IND-ready candidates. The company's portfolio draws from a proprietary library of 20,000 gut hormone peptides and conjugates, with recent licensing of candidates from South Korean biotech D&D Pharmatech in a deal worth over 1 trillion Korean won ($740 million) in fees and milestones. Led by CEO Clive Meanwell, formerly of The Medicines Company (acquired by Novartis for $9.7 billion), Metsera aims to address next-generation needs like weight maintenance, muscle preservation, less-frequent dosing, and improved efficacy beyond current GLP-1 leaders from Novo Nordisk and Eli Lilly. Subsequently, Metsera raised a $215 million Series B in late 2024 led by Wellington Management and Venrock, bringing total funding over $500 million. Later developments include a Nasdaq IPO, additional venture funding with ARCH as largest stakeholder, and a $10 billion acquisition by Pfizer after a bidding war with Novo Nordisk.
