INCHEON, South Korea, — Samsung Biologics has announced the launch of an all-cash public tender offer to acquire 100% of the fully diluted share capital of PolyPeptide Group AG, a leading global contract development and manufacturing organization (CDMO) specializing 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 specialized 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.

Upon completion of the transaction, Samsung Biologics will bring together PolyPeptide’s highly experienced team and specialized 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.

“This acquisition reinforces our long-term growth strategy by not only broadening our service portfolio with modality expansion into peptides including GLP-1, but by also boosting our geographic reach and proximity further within the US, Europe, and India,” said John Rim, Chairman of the Board of Directors and CEO of Samsung Biologics. “We highly value PolyPeptide’s world-class employees, industry-leading capabilities, and global operational footprint, and look forward to leveraging the complementary strengths of PolyPeptide and Samsung Biologics in our continued growth supporting clients as the CDMO of choice for decades to come.”

Indicative timeline
The offer by Samsung Biologics is conditioned upon at least two-thirds of all PolyPeptide shares on a fully diluted basis being tendered into the offer at the end of the offer period, together with other customary offer conditions, including the regulatory approvals set out in the pre-announcement.

The tender offer is expected to be launched by the end of August 2026 by publication of the formal offer prospectus and will remain open for a minimum of twenty trading days on the SIX Swiss Exchange (“SIX”), following a ten trading-day cooling-off period under Swiss takeover law.

Once the offer has been successfully completed, Samsung Biologics intends to pursue a squeeze-out of any remaining minority shares and to delist PolyPeptide from the SIX, at which point PolyPeptide would become a wholly owned subsidiary of Samsung Biologics.
