Pharmaceutical giant Pfizer to invest $650 million in new Groton manufacturing center
Pfizer plans to invest $650 million over five years to build a 220,000-square-foot Manufacturing Technology Center in Groton. The facility will support clinical trials and consolidate employees from other campus buildings. Construction is set to begin in Q2 2027, with operations starting in mid-2031. The Groton campus is a key R&D hub for Pfizer, employing around 4,000 people.
