SAN JOSE — Momentus has struck a deal to sublease a big chunk of research and office space in San Jose from QuantumScape Battery in a deal that is poised to alter the respective South Bay footprints of each company.
The sublease involves the entire building at 1762 Automation Parkway in north San Jose, according to a regulatory document that QuantumScape Battery, a unit of QuantumScape Corp., filed with the Securities and Exchange Commission.

The building that QuantumScape has agreed to sublease to Momentus totals 61,100 square feet, the regulatory filing with the SEC shows.
QuantumScape, a creator of advanced battery technologies, and Momentus, a commercial space company whose products include low-orbit vehicles, both have established their corporate headquarters in north San Jose.
Momentus will likely begin occupying the building sometime in 2026. The rental agreement for the building where Momentus will set up shop is slated to expire in September 2032, according to the QuantumScape filing with the SEC.
QuantumScape began leasing the building in late 2021 under a rental agreement that it had struck with the building’s owner, an affiliate of Peninsula Land & Capital, according to the SEC filings and a market report prepared at that time by Colliers, a commercial real estate firm.
Momentus has its headquarters at 3901 North First St. in San Jose. QuantumScape’s headquarters are at 1730 Automation Parkway in San Jose. It wasn’t immediately known whether Momentus would retain its North First Street headquarters once the sublease agreement begins.
QuantumScape is currently focusing more on developing new battery technologies that it licenses to its auto industry partners, such as the battery manufacturing arm of Volkswagen.
The company’s rental deal with Momentus fits that QuantumScape strategy.
“This sublease results in a smaller operational footprint consistent with the company’s technology licensing focus,” QuantumScape stated in the regulatory filing.
