The investment will include the design, reconstruction and fit-out of an existing 1-million-square foot facility on Duplainville Road.
“For nearly four decades, New York has been a strong partner to Regeneron, helping us become a leading biotechnology company and the place where we’ve invented some of the most transformative medicines in biotechnology,” said Regeneron Co-Chair, President and CEO Leonard S. Schleifer, M.D., Ph.D. “As Regeneron continues to drive forward our mission of using the power of science to bring forward life-changing medicines we can improve the lives of those in New York and around the world. In this pursuit, we look forward to continuing to fuel economic development and create meaningful, well-paying jobs that strengthen communities across the state.”
The project is being supported by Empire State Development with up to $35 million in performance-based Excelsior Jobs Program tax credits.
“Regeneron’s continued growth in New York is a powerful testament to our state’s robust life sciences ecosystem, our unmatched talent pipeline, and strategic industry investments championed by Governor Hochul,” noted Empire State Development President, CEO and Commissioner Hope Knight. “This $2 billion expansion and the creation of 1,000 new jobs in the Capital Region demonstrates how innovative companies and New York State can work together to drive transformative economic development, and Empire State Development is proud to support projects that fuel innovation, strengthen communities, and deliver life-changing breakthroughs for New Yorkers and people around the world.”
Regeneron Pharmaceuticals discovers, develops, and sells medicines for serious diseases in areas like immunology, oncology, and rare diseases. The company is known for treatments such as Eylea (eye diseases), Dupixent (inflammatory diseases like eczema and asthma), and its COVID-19 antibody treatment.
“Regeneron’s investment in Saratoga Springs is a powerful vote of confidence in the Capital Region’s workforce and economic momentum,” added Center for Economic Growth President and CEO Mark Eagan . “This project will breathe new life into a major facility, create more than a thousand quality jobs, and strengthen our region’s position as a leader in biotech.”
“The Regeneron new investment in Saratoga County will be among the largest commercial investment both in money and job creation in Saratoga County history, surpassed only by the GlobalFoundries investment of $15 billion dollars in the Towns of Malta & Stillwater,” said Saratoga Economic Development Corporation President and CEO Greg Connors. “Regeneron considered sites both nationally and internationally for this investment. Governor Hochul and Empire State Development are to be congratulated for again making New York State, and in this case Saratoga County a great place for 21st century advanced manufacturing investment and job creation. This investment is testament to the collaboration and “can do” spirit by state, county, local government as well as our Saratoga County business and economic development stakeholders that Saratoga County and New York State are a great place to live, work, raise a family and a place for capital investment.”
