Samsung Biologics to Acquire PolyPeptide for $1.8 Billion in GLP-1 Market Push

Samsung Biologics Co Ltd (KS:207940) announced on Monday it will acquire Switzerland’s PolyPeptide Group AG (SIX:PPGN) in an all-cash transaction valued at approximately 1.46 billion Swiss francs ($1.8 billion). The move marks a significant strategic expansion for the South Korean contract drugmaker into the rapidly growing market for peptide-based therapies.
Deal Details
Under the terms of the agreement, Samsung Biologics will offer 44.31 Swiss francs per share. This represents a 6.1% premium to PolyPeptide's closing share price on the preceding Friday. The transaction is expected to close by the end of 2026, pending regulatory approvals and other standard closing conditions.
The deal has received strong backing from the Swiss firm. PolyPeptide's board of directors has unanimously recommended the offer, and shareholders representing about 55.65% of the company's shares have already committed to tender their holdings, according to the announcement.
Strategic Rationale
AdThe acquisition is designed to bolster Samsung Biologics' capabilities in producing peptide active pharmaceutical ingredients (APIs). The company specifically highlighted the rising global demand for GLP-1 agonists, a class of drugs widely used in popular obesity and metabolic disease treatments.
By acquiring PolyPeptide, Samsung Biologics will also gain a significant global manufacturing footprint. The deal includes PolyPeptide's facilities in Sweden, Belgium, France, the United States, and India, providing an immediate and geographically diverse expansion.
Market Reaction
Following the announcement, shares of Samsung Biologics fell 3.4% to 1,354,000 won in Seoul trading on Monday. However, the company's stock outperformed the broader South Korean market, as the KOSPI index dropped a steeper 4.1% during the same session.
