NORWICH – The roughly 400 employees of OSG Norwich Pharmaceuticals, based in North Norwich, learned this week that an announcement could be made as soon as August about a new owner of the company.

“We hope to be able to get something out to the public by the end of the month. I can tell you that I am very excited about it,” President Chris Calhoun said Wednesday.

Negotiations with prospective buyers for the outsourcing manufacturer and packaging services provider have been ongoing since April. In June, management of Woodcliff Lake, N.J.-based OSG said that it would be exiting the pharmaceutical business.
