Merck & Co. To Sell New Jersey Campus to Onyx Equities

Merck & Co. has agreed to sell its 108-acre campus in Kenilworth, New Jersey, to Onyx Equities, a Woodbridge, New Jersey-based real estate firm. The pending sale follows Merck’s decision to re-locate its headquarters to Rahway, New Jersey, the birthplace of the company in the US.  

Merck, which moved to its new headquarters site in Rahway in 2022, will begin a process of vacating the Kenilworth property in phases over the next several years while its new headquarters in Rahway completes a planned expansion.  

Merck had announced in 2020 that it planned to consolidate its New Jersey sites at a new headquarters site in Rahway. The company has been headquartered in Kenilworth since 2015 following a move from Whitehouse Station, New Jersey, where the company had been headquartered since 1992. Prior to that, it was headquartered in Rahway. Merck gained the Kenilworth site from its $41-billion acquisition of Schering-Plough in 2009.  

The Rahway site has grown over the past 120 years from one manufacturing plant to more than 200 acres focused on discovery and development.
