A Waltham life science campus has been sold to a California real estate investor after attracting a Cambridge biomanufacturing tenant under the seller’s repositioning project.

TPG Real Estate’s Alloy life science platform sold the Centerpoint campus for $578 million to CS Capital Management of Newport Beach, California.

The transaction was first reported by Bisnow.

TPG bought the nearly 600,000-square-foot campus in 2020 for $340 million with a strategy of attracting more life science tenants through a lab conversion.

In July 2021, Cambridge-based Generation Bio Co. signed a 12-year, 104,000 square feet for a biomanufacturing facility at 41 Seyon St., with total payments of $104 million.

The campus includes the former Standard Thomson Co. headquarters at 152 Grove St., known as the Gauge, and the former Raytheon R&D center at 41 Seyon St. and 43 Foundry Ave.

TPG’s Alloy Properties platform expanded into Greater Boston acquisitions in 2021.
