South Korea-based Samsung Biologics, a leading contract development and manufacturing organization (CDMO), has announced that its wholly owned US subsidiary, Samsung Biologics America, has entered into a definitive agreement to acquire 100% of Human Genome Sciences from GSK. This strategic move secures Samsung Biologics' first US-based manufacturing site, a significant expansion of the company's global footprint and its long-term commitment to the US market.
Located in Rockville, Maryland, the facility sits at the center of one of the key US bio-clusters and encompasses two cGMP manufacturing plants with a combined 60,000 liters of drug substance capacity, supporting both clinical and commercial production from small to large scale. Existing products will continue to be manufactured at the site, and Samsung Biologics plans to make additional investments to expand the site's capacity and upgrade technology to further support a more resilient US supply chain for critical biologic medicines.
Under the terms of the agreement, with closing anticipated toward the end of Q1 of 2026, Samsung Biologics will acquire the Rockville assets for $280 million. The company will also retain more than 500 employees at the site to ensure operational continuity and stability. By integrating this facility into our global network, Samsung Biologics will provide clients with flexible, multi-site options in both the US and Korea to ensure that live-saving therapeutics are reliably available to American patients.
