Johnson & Johnson to Build $1 Billion Cell Therapy Plant in Pennsylvania

The facility marks a step in J&J’s $55 billion U.S. expansion, influenced by tariff policies, backed by $41.5 million in state incentives.

Overview

  • J&J confirmed the Montgomery County site on its Janssen Biotech campus in Lower Gwynedd near Ambler.
  • The company projects more than 4,000 construction roles and about 500 permanent biomanufacturing jobs.
  • The next-generation facility will expand capacity for medicines targeting cancer, immune-mediated disorders and neurological diseases.
  • Pennsylvania offered $41.5 million in support, and local reports point to a 154-acre parcel at 1201 Sumneytown Pike.
  • J&J has not announced an opening date, though some local reports cite 2031, and the project fits into a $55 billion U.S. build-out that includes work in Wilson, North Carolina and momentum from the approved cell therapy Carvykti.
