Target

PolyPeptide Group is a SIX-listed peptide CDMO headquartered in Baar, Switzerland, with manufacturing sites in Sweden, Belgium, France, the US and India, over 70 years of API manufacturing heritage and more than 1,000 therapeutic peptides produced. FY2025 revenue was EUR 389.3 million and EBITDA EUR 46.8 million (12.0% margin).

Deal rationale

Samsung Biologics said the deal expands its CDMO modalities beyond antibodies and ADCs into peptides, citing demand for obesity and diabetes treatments including GLP-1, and adds US, European and Indian manufacturing footprint, combining its facility design and operations capability with PolyPeptide's peptide technology. The all-cash tender offer of CHF 44.31 per share (implied equity value about CHF 1.46 billion, 40% premium to the unaffected price) has a 66⅔% minimum acceptance condition; largest shareholder Draupnir Holding (55.65%) committed to tender, and delisting is planned after completion.

Lead

Samsung Biologics is acquiring PolyPeptide Group, a peptide contract development and manufacturing organisation (CDMO) listed on the SIX Swiss Exchange. On 20 July 2026 it announced an all-cash tender offer of CHF 44.31 a share, valuing 100% of the equity at CHF 1.46bn, or about $1.9bn. The largest shareholder, Draupnir Holding (55.65%), has irrevocably agreed to tender.

USD figures are converted at KRW 1,450 = USD 1.

Why this matters

It is described as the largest overseas acquisition by a Korean pharmaceutical or biotech company. The offer is a roughly 40% premium to the undisturbed share price of 10 April. Samsung Biologics approved a $2.1bn rights issue on 28 August, of which about $1.9bn will fund the purchase.

Strategic context

Samsung Biologics is extending its CDMO business beyond antibodies and antibody-drug conjugates (ADCs) into peptides. As GLP-1 obesity drugs spread and demand for peptide manufacturing grows, it gains PolyPeptide’s plants in the US, Europe and India. The offer is being made through its Swiss vehicle, Samsung Peptide.

What’s next

The tender runs from 15 September to 12 October and requires at least 66.7% acceptance plus regulatory approvals. If Samsung reaches 90%, it plans to squeeze out the remaining shareholders and delist the company, with closing targeted for the end of November.
