$650M Pfizer Groton Manufacturing Center: Production Returns to Site
Pfizer plans to invest $650M in a 220,000 sq ft Manufacturing Technology Center at its Groton, CT campus, starting construction in Q2 2027 and targeting operations by mid-2031. The facility will produce clinical trial materials, consolidating existing staff. The project follows Pfizer's agreement with the U.S. government for R&D investments and aligns with state economic strategies. The campus currently employs around 4,000 people and is a major taxpayer in the area.
