Samsung Biologics has launched a cash public tender offer to acquire 100% of PolyPeptide Group AG, a leading global contract development and manufacturing organisation (CDMO) specialising in peptide-based active pharmaceutical ingredients (APIs).
Under the terms of the offer, PolyPeptide shareholders will receive CHF 44.31 in cash for each PolyPeptide share, representing an implied equity value of approximately CHF 1.46 billion. The transaction is expected to be completed towards the end of 2026.
After a comprehensive review of strategic options, PolyPeptide’s board of directors, acting through its independent and non-conflicted members, unanimously recommend that PolyPeptide shareholders accept the tender offer, subject to the terms and conditions set forth in the offer prospectus. The board determined that the transaction represents an attractive outcome for shareholders and PolyPeptide while positioning PolyPeptide for its next phase of growth as part of Samsung Biologics’ global CDMO platform.
With this transaction, Samsung Biologics will expand its capabilities beyond antibodies and ADCs to include peptide therapeutics, one of the fastest-growing segments of the biopharmaceutical industry, driven by surging global demand for obesity treatments and the continued expansion of peptide-based therapies into new disease areas. The transaction brings together Samsung Biologics’ global manufacturing scale with PolyPeptide’s specialised peptide expertise to create a differentiated, end-to-end multi-modality CDMO platform. PolyPeptide stands as one of the industry’s top peptide CDMOs, distinguished by its advanced technology platform and proven track record, with more than 70 years of API manufacturing heritage and over 1,000 therapeutic peptides produced to date.
PolyPeptide operates an integrated development-to-commercial model with growth focused on a modular, automation approach, giving it the flexibility to adapt quickly to changing market demand. Through PolyPeptide’s peptide capabilities, innovative technologies, and proven commercial manufacturing track record, Samsung Biologics aims to serve clients across a broader range of therapeutic modalities by addressing growing demand for peptide-based therapeutics, particularly in obesity and diabetes, including GLP-1 therapies, while advancing innovation across high-growth areas such as oncology and other emerging indications.
The planned acquisition extends beyond adding capacity; it lays the foundation for Samsung Biologics’ next phase of growth, supported by a strong pipeline of active peptide projects that includes a deep late-stage portfolio. PolyPeptide operates global sites across Sweden, Belgium, France, the United States, India, together with a corporate office in Switzerland and a separate Innovation Center in Strasbourg, France, with capabilities encompassing R&D, development and commercial manufacturing.
Upon completion of the transaction, Samsung Biologics will bring together PolyPeptide’s highly experienced team and specialised peptide expertise, further enhancing its capabilities. By combining the companies’ scientific strengths, manufacturing excellence, and global operations, the transaction is expected to enhance operational excellence, unlock additional growth opportunities, and further strengthen Samsung Biologics’ position as a leading global multi-modality CDMO.
