July 20 (Reuters) – South Korea’s Samsung Biologics will launch a 1.46 billion Swiss francs ($1.81 billion) all-cash bid for Swiss contract drugmaker ​PolyPeptide, the companies said in separate ‌statements.

The offer at 44.31 Swiss francs per share represents a premium of about 6.1% to PolyPeptide’s last closing price of 41.75 Swiss francs on Friday, according to a ‌Reuters ​calculation.

The tender offer is ⁠expected to launch by ⁠the end of August and close by year-end, Samsung Biologics said.

The takeover would expand the South Korean firm’s capabilities in peptide-based therapeutics, including fast-growing ​obesity and diabetes treatments such as GLP-1 drugs, the company said.

PolyPeptide said its board ⁠had unanimously recommended shareholders accept ⁠the offer.

Samsung Biologics said after the ​deal was completed it aimed to pursue a ​squeeze-out of any remaining minority shares and would ‌delist PolyPeptide from the SIX Swiss Exchange, making it a wholly owned unit of the company.

PolyPeptide said its largest individual shareholder, Draupnir Holding, ⁠which owns about 55.65% of the company, supported the deal and would tender all of its shares into ⁠the offer.

The ‌Swiss company said in April ⁠that Draupnir was conducting a review ​of strategic ‌options with regard to its ​majority stake ⁠in PolyPeptide.

Draupnir’s parent entity is the Cryosphere Foundation, which has links to Swedish billionaire Frederik Paulsen, PolyPeptide has said previously.
