SEOUL, Dec 22 (Reuters) – South Korea’s Samsung Biologics said on Monday it ‍is acquiring its first U.S. drug production facility from GSK for $280 million to respond to long-term U.S. ‌market demand.

The company’s U.S. ‌unit Samsung Biologics America is acquiring a 100% stake in the U.S. drug production facility ​called Human Genome Sciences Inc, in Rockville, ‍Maryland, the South ​Korean drug contract ​manufacturer said in a statement.

The ‍facility currently has a combined 60,000 liters of drug substance capacity, and the drug contract manufacturer ‍Samsung Biologics plans additional investments to expand the site’s capacity and ‍upgrade ‍technology, it said.

The ​acquisition value may ​change ⁠when the deal closes, ‌likely around the end of the first quarter of 2026, Samsung Biologics said.
