Impinj extends Seattle office lease to 2038, adds 6,563 sq ft
Impinj signed a Fifth Amendment to its Seattle office lease, extending the term to January 31, 2038 and adding about 6,563 rentable square feet, which brings the premises to roughly 70,995 square feet. The company expects total base rent for existing space from September 1, 2025 through the lease term to be about $44 million, with additional rent for the expansion space starting when it becomes available. This is a routine real estate commitment, with a landlord rent abatement and a $5 million tenant improvement allowance offsetting some costs.
