Biopharmaceutical company GSK plans to expand its operations in Upper Merion Township, Pennsylvania. The more than $800 million project is expected to create over 300 jobs over the next five years in Montgomery County.

The investment will include the construction of a biopharmaceutical innovation and manufacturing campus, featuring a commercial-scale biologics manufacturing facility, a research and development pilot plant, a centralized quality control laboratory and a manufacturing science and technology hub.

“Investing in additional commercial and R&D manufacturing with advanced digital capabilities at our Upper Merion site will help accelerate the development and supply of future medicines for patients,” said GSK Global Supply Chain President Regis Simard. “The Commonwealth of Pennsylvania has been an important partner in supporting GSK’s growth, innovation, and manufacturing footprint in the United States. By expanding in Upper Merion, we’re building on that longstanding partnership while creating high-quality jobs and strengthening our ability to deliver the next generation of medicines.”

To support the project, GSK will be eligible for tax benefits through Pennsylvania’s Qualified Manufacturing Innovation and Reinvestment Deduction program and Manufacturing Tax Credit program.

“GSK’s decision to make another major investment in Pennsylvania is a strong signal that we have the innovation ecosystem, talent, and infrastructure to support the next generation of biopharmaceutical manufacturing,” noted Pennsylvania Department of Community and Economic Development (DCED) Secretary Rick Siger. “This project will create hundreds of new jobs, strengthen the economy, and build on GSK’s longstanding commitment to Pennsylvania. The Shapiro Administration will continue to support and invest in companies that further boost our economy and provide real opportunity for Pennsylvanians.”

GSK specializes in the research, development, and manufacturing of prescription medicines and vaccines. The company’s operations include pharmaceutical research, clinical development, biologics manufacturing, and the production of treatments and vaccines for infectious diseases, respiratory conditions, oncology, and immunology.
