As HQ move nears completion, Merck finds a buyer for its sprawling Kenilworth campus

Three years after Merck & Co. unveiled a headquarters pivot back to its old stomping grounds in Rahway, New Jersey, the company is bidding goodbye to its previous Garden State home base.

Merck has reached a deal with real estate business Onyx Equities to sell its 108-acre campus in Kenilworth, New Jersey, where the drug behemoth relocated its main digs back in 2015. For 23 years before that, Merck was based in nearby Whitehouse Station.
