- Sanofi will lay off 229 workers in Massachusetts, according to records filed with the state's Executive Office of Labor and Workforce Development.
- The affected employees were hired through Blueprint Medicines, a Cambridge-based biotech that Sanofi acquired for $9.1 billion in July 2025.
- Sanofi ranks as one of Massachusetts' largest pharmaceutical employers, making the cuts a notable event in the state's biotech labor market.
- The positions will be eliminated between Oct. 9 and late June 2027, spreading the reductions across roughly eight months.
- The layoffs come a little over a year after the acquisition closed, marking one of the first major workforce consequences of the Blueprint deal.
Why it matters: Sanofi paid $9.1 billion for Blueprint Medicines in July 2025; roughly a year later it is cutting all 229 of the acquired unit's Massachusetts positions, phased out over eight months through late June 2027. For one of the state's largest pharma employers, that is a concentrated wipeout of the workforce attached to its biggest recent biotech buy.
