Biotech company laying off dozens as it closes CT facility

October 1, 2025

An international biotechnology company that is headquartered in Connecticut is laying off 68 employees in the state.

PerkinElmer U.S. LLC is permanently closing its manufacturing facility at 710 Bridgeport Ave., Shelton, and laying off the employees that work there, the company said in a notice to the Connecticut Department of Labor.

The first phase of the closure will take place Nov. 24 and employees to be laid off on that date have already been notified. Future employees will be notified at least 60 days in advance of their termination, according to the notice.

The layoffs are expected to be permanent, the company said and the employees are not represented by a union.

PerkinElmer, a biotechnology company, lists its headquarters as the same Shelton address. Representatives for the company could not be reached Tuesday.

The company has more than 50,000 employees and offices in 35 countries, according to its website, which calls PerkinElmer “A leading provider of end-to-end discovery, measurement & testing solutions and specialized Pharma services.”

A Courant article from 2018 said PerkinElmer had 500 employees in Shelton and its headquarters were then in Massachusetts. At that time, the company eliminated 75 jobs as it moved four product lines to England and Singapore. The vice president of manufacturing said then that the shift would move the product lines closer to “the fastest growing markets in the world,” noting that the developing world accounted for 25% of the company’s revenues.
