PolyPeptide's independent Board of Directors unanimously recommends that shareholders accept Samsung Biologics' offer. The transaction would substantially expand Samsung Biologics' peptide CDMO manufacturing footprint beyond its existing antibody and antibody-drug conjugate focus, positioning the combined entity to address the rapidly growing peptide therapeutics demand particularly in obesity and diabetes GLP-1 therapies (Novo Nordisk Wegovy and Ozempic, Eli Lilly Zepbound and Mounjaro), amylin analogs (cagrilintide), and next-generation combination peptide drugs. PolyPeptide operates commercial-scale peptide API manufacturing across the US, Europe, and India.

Samsung Biologics announced Sunday-Monday July 19-20, 2026 an all-cash public tender offer to acquire Switzerland's PolyPeptide Group for CHF 1.46 billion ($1.8 billion) at CHF 44.31 per share, a 40% premium to the undisturbed share price of CHF 31.65. The transaction represents the largest biopharmaceutical M&A in South Korean history. Strategic rationale: PolyPeptide is a global peptide contract development and manufacturing organization (CDMO) with accelerating revenue growth driven by rising client demand for peptide-based GLP-1 therapies for obesity and diabetes. The acquisition expands Samsung Biologics' capabilities beyond monoclonal antibody manufacturing (its historical strength) into peptide therapeutics and adds PolyPeptide's global network spanning Sweden, Belgium, France, the United States, and India, encompassing R&D, development, and commercial manufacturing capabilities. PolyPeptide's Board of Directors unanimously recommends the offer. The largest shareholder has given an irrevocable tender undertaking representing approximately 55.65% of outstanding shares. Samsung Biologics expects to complete the deal by end of 2026. The deal extends the July 2026 peptide-manufacturing consolidation wave alongside Novartis's $1.5 billion Myricx Bio acquisition (ADC payloads, July 6) and Lonza's Nona Biosciences TfR1 blood-brain-barrier deal (July 2).
