Montgomery County Celebrates Opening of Samsung Biologics’ First U.S. Manufacturing Facility in Rockville

For Immediate Release: Wednesday, April 1, 2026

Montgomery County Executive Marc Elrich joined Maryland Governor Wes Moore, Lt. Governor Aruna Miller, Rep. April McClain Delaney, Montgomery County Council President Natali Fani-González, Rockville Mayor Monique Ashton, executives from Samsung Biologics, and other industry leaders for the ribbon-cutting of Samsung Biologics' first United States manufacturing facility in Rockville. The $353 million acquisition of the former GSK manufacturing campus retains more than 500 local jobs, brings an additional 60,000 liters of drug substance capacity to the company's operations, and establishes a foundation for future facility investment and expansion.

"Samsung Biologics is a global leader in biomanufacturing, known for excellence, scale, and precision, and the company's decision to establish its first U.S. biomanufacturing presence in Montgomery County, Maryland speaks volumes about our attractiveness to international companies," said County Executive Elrich. "Montgomery County sits at the heart of the nation's third-largest biohealth hub. We are home to the National Institutes of Health, the U.S. Food and Drug Administration, and the University of Maryland's Institute for Health Computing, alongside a dynamic cluster of private sector companies advancing breakthroughs in biotech, research and development, manufacturing, and health innovation. We are proud to be a County and State designed to move ideas from discovery to delivery. We welcome Samsung Biologics to Montgomery County."

"During our international trade mission last year, we met with the Samsung Biologics team in Seoul to discuss the economic momentum in Maryland, said Gov. Moore. "Today's ribbon cutting is the realization of that meeting and our state's momentum. South Korea's largest biotech company is opening its first U.S. manufacturing facility here in Maryland. In the state of Maryland, we are delivering for our people and not playing for second."

Headquartered in Songdo, Incheon, South Korea, Samsung Biologics is a global biotechnology company focused on the development, manufacturing, and commercialization of biologic drugs. The new Rockville facility comprises two manufacturing plants supporting both clinical and commercial biologics production, boosting the company's total global capacity to 845,000 liters. In the coming months, the company plans to evaluate existing site capabilities and equipment for further capacity expansion, technology upgrades, and additional capital investments.

"This represents a meaningful step in expanding our U.S. manufacturing footprint," said Samsung Biologics President and Chief Executive Officer John Rim. "The addition of the Rockville site strengthens our ability to operate a geographically diversified manufacturing network, and we are thrilled to officially welcome more than 500 colleagues at the site to the Samsung Biologics family. The Rockville team brings deep expertise and strong operational experience that will further strengthen the site as part of our global manufacturing network. As a CDMO, our mission is to help our partners bring important therapies to patients worldwide, and this site will play a pivotal role in that mission, while ensuring continuity and upholding the high standards our clients expect."

"The ribbon-cutting is the result of true partnership and visionary leadership," said Council President Natali Fani-González. "Gov. Wes Moore saw an opportunity to bring Samsung Biologics to our growing biohealth hub in Maryland, and he worked closely with the City of Rockville and Montgomery County to ensure it would happen. We celebrate the first day of Samsung Biologics' manufacturing operations in Rockville."

"Samsung Biologics' investment in Montgomery County is a major win for Maryland and a clear example of how public investment and global partnerships help drive innovation, business, and workforce opportunities and improve the health and well-being of our communities," said Congresswoman Delaney. "As a member of the House Science, Space, and Technology Committee, I have seen how sustained federal support for research helps attract cutting-edge companies to our region. Located along the I-270 Technology Corridor, this new facility will benefit from Maryland's uniquely collaborative innovation ecosystem-where federal labs, universities, and industry collaborate to drive progress. We're proud to welcome Samsung Biologics to our science community and to celebrate their new facility."

"We are thrilled and appreciative that Samsung Biologics decided to establish its first U.S. manufacturing campus in the greater Rockville, Maryland Biotech Corridor, one of the nation's leading biotech hubs," said Rockville Mayor Monique Ashton. "This is so much more than a brick building being filled. This expansion will bring global leadership in biomanufacturing to Rockville, it will be a source of life-saving therapies for patients around the world, and it will foster sustained economic opportunity for our region-supporting hundreds of skilled jobs today while laying the foundation for future growth in our life sciences workforce."

"We are proud to join the State of Maryland and Montgomery County in welcoming Samsung Biologics to Rockville and celebrating this important milestone," said Montgomery County Economic Development Corporation President and Chief Executive Officer Jared Smith. "This decision reflects the confidence global industry leaders have in our business environment. Samsung Biologics' presence will further strengthen our life sciences ecosystem and help drive meaningful opportunities for innovation, collaboration, and economic growth."

The launch of the Samsung Biologics facility builds on a series of commitments from internationally based companies to expand Maryland and Montgomery County's life sciences and biopharmaceutical sectors, and from overseas organizations supporting business growth in Montgomery County, Maryland. Montgomery County's sister city, Daejeon in South Korea, opened its Global Trade Center here last year; Intellian continues to expand capacity at the $100m R&D facility it opened here in 2023; and Rapigen, Sotirion, and Grassmedi are three Korean-based companies seeking to grow U.S. operations that are now in the Montgomery County innovation centers.

"Samsung Biologics joins one of the top biopharma clusters in the country with this move into Maryland," said Maryland Department of Commerce Secretary Harry Coker, Jr. "With its innovative portfolio and dedication to life-saving therapeutics, the company's impact is felt throughout the world. Maryland is honored to play a role in that important work."

"Samsung Biologics' arrival in Rockville is a defining milestone in a relationship built on years of mutual respect, cultural exchange, and friendship," said Maryland Secretary of State Susan Lee. "This new facility signals a next chapter of shared success and economic growth that will benefit both Marylanders and the people of Korea for years to come. We are proud to see our enduring alliance translate into tangible, world-class innovation that will improve healthcare outcomes across the globe."

Recent economic development announcements across Maryland include major investments in life sciences manufacturing, research, and workforce development. With nearly 5,000 life science businesses supporting more than 54,000 employees statewide, Montgomery County remains a central part of this ecosystem, offering proximity to federal agencies, leading research institutions, and a highly skilled workforce.
