Samsung Biologics to Acquire U.S. Drug-Production Facility via 100% Stake in Human Genome Sciences

Seoul, Dec 22 – Samsung Biologics, through its U.S. unit, has announced a landmark deal to acquire a U.S. drug production facility by taking full ownership of Rockville, Maryland-based Human Genome Sciences Inc. The transaction is valued at about $280 million and aims to meet growing long‑term demand in the American market.

The U.S. unit, known as Samsung Biologics america, will purchase a 100% stake in Human Genome Sciences, signaling the South Korean CDMO’s first full control of a U.S. manufacturing platform. The move is framed as a strategic response to sustained demand for biologics and complex drugs in the United States.

Samsung Biologics plans to invest further in the site to expand capacity and upgrade technology. The existing footprint totals 60,000 liters of drug-substance capacity, with officials signaling a expansion push once the deal closes.

While the deal’s final value could shift before closing, Samsung Biologics indicated a closing window likely around the end of the first quarter of 2026.

In related developments, another South Korean player, Celltrion, has also signaled plans to produce drugs in the United states, reflecting a broader push by Asian contract manufacturers to strengthen U.S.capabilities amid policy discussions on tariffs and onshoring pharmaceutical production.

Under a bilateral framework with the United States, tariffs on U.S. imports of South Korean pharmaceuticals are expected to be capped at 15% for branded drugs,with generics remaining tariff-free. This backdrop underscores why U.S. production footholds are increasingly strategic for CDMOs seeking long-term market access.

Market reaction to the announcement was modest, with Samsung Biologics shares dipping about 0.4% on the session, as investors weighed the deal against broader market moves.
