Seoul/Washington, D.C.
South Korea’s Samsung Biologics has announced its acquisition of its first U.S.-based drug production facility from GSK for $280 million, marking a significant step in the company’s strategy to meet long-term demand in the U.S. pharmaceutical market. The acquisition will be executed through Samsung Biologics’ U.S. subsidiary, Samsung Biologics America, which will take full ownership of the Rockville, Maryland-based Human Genome Sciences Inc. facility.
The Rockville site currently has a combined 60,000-liter drug substance capacity, and Samsung Biologics has outlined plans for additional investments to expand production capabilities and upgrade technology. The transaction is expected to close by the end of the first quarter of 2026, with the final acquisition value subject to adjustments at that time.
This move aligns with broader trends in the biopharmaceutical sector, as companies such as Celltrion also look to expand drug manufacturing operations in the United States. The acquisition comes amid regulatory and trade considerations, including a U.S.-South Korea agreement capping tariffs on South Korean pharmaceutical imports at 15%, with generic drugs remaining tariff-free.
Samsung Biologics’ stock responded modestly, reflecting a 0.4% decline on the day of the announcement, underperforming the broader market’s 2% gain.
The company’s strategic expansion into the U.S. underscores its commitment to supporting global supply chains and addressing rising demand for contract drug manufacturing in North America.
