Indian financial newspaper Business Standard reported https://www.business-standard.com/article/companies/pfizer-to-stop-manufacturing-operations-in-chennai-aurangabad-units-119010801430_1.html the news on Tuesday, saying over 1,700 employees would be impacted by the closure of the two factories in the states of Tamil Nadu and Maharashtra.
The factories employ nearly 6 percent of Pfizer's global manufacturing workforce.
"Pfizer has conducted a thorough evaluation of the ... sites in India and concluded that due to the very significant long term loss of product demand, manufacturing at these sites is not viable," the company said in an emailed statement.
Pfizer acquired the sites as part of its $15 billion (£11.7 billion) purchase of Hospira Inc in 2015, to boost its portfolio of generic injectable drugs and copies of biotech medicines.
The plant in Chennai makes generic injectable cephalosporin, penems and penicillin. The Maharashtra plant supplied the Chennai unit with certain products.
Both plants do not manufacture products for the India market, Pfizer said, adding that it is expanding operations in its Visakhapatnam facility in south India.
