A Boxborough-based manufacturer is shifting its operations to New Hampshire early next year, uprooting hundreds of workers in the process.
SynQor, which makes power converters for the military, industrial, avionics, rail transportation, medical, and telecom markets, told state officials they expect the move will occur between Feb. 1 and April 1, 2026.
All positions and jobs at the company’s Boxborough headquarters will be transferred to the new facility in Salem, New Hampshire, during the same timeframe, SynQor general counsel John Cancellara wrote in a Nov. 21 letter to the Executive Office of Labor and Workforce Development.
SynQor’s new facility will be located at 9 Northeastern Blvd. in Salem, just under an hour’s drive from the company’s current home in Boxborough.
The company filed a Worker Adjustment and Retraining Notification Act notice with the state on Nov. 25, putting the number of impacted employees around 250. As the state’s website explains, the WARN Act requires employers with 50 or more workers to provide 60 days’ written notice before closing a plant or implementing a mass layoff.
Per Cancellara’s letter, SynQor’s executives, engineers, technicians, and assembly workers are among the employees whose jobs are being shifted to New Hampshire.
“Employees are not represented by a union and there are no bumping rights,” Cancellara wrote. “Each of these team members impacted will receive a written 60-day notice of position transfer.”
SynQor did not immediately respond to a request for comment Wednesday.
Founded in 1997 and originally based in Hudson, Massachusetts, the company currently operates out of its 100,000-square-foot headquarters at 155 Swanson Road in Boxborough. SynQor also has a second design facility in Dallas, Texas, and additional sales offices throughout North America, Europe, and Asia, according to its website.
