Item 1.01 Entry into a Material Definitive Agreement

 

On October 30, 2025, Impinj, Inc. (the “Company”) entered into a Fifth Amendment to Office Lease (the “Lease Amendment”) with 400 Fairview Avenue LLC (“Landlord”) to amend the Office Lease dated as of December 10, 2014, as amended (the “Lease”) relating to the Company’s office space in Seattle, Washington (the “Premises”). The Lease Amendment extends the term of the Lease to January 31, 2038 and provides the expansion of the Premises by approximately 6,563 rentable square feet (the “Expansion Space”). Upon inclusion of the Expansion Space and remeasurement of the Premises, the Company will lease approximately 70,995 rentable square feet. The total base rent for the existing premises beginning on September 1, 2025, the retroactive effective date of the Lease Amendment, through the term of the Lease is expected to be approximately $44 million and the Company will pay additional base rent for the Expansion Space beginning when it is made available for occupancy through the term of the Lease. In addition to monthly base rent, the Company will continue to pay as additional rent its proportionate share of certain operating expenses, insurance costs and taxes for each calendar year during the term of the Lease. As an inducement to enter into the Lease Amendment, the Landlord also agreed to provide the Company with a base rent abatement for the existing space for the eight-month period from September 1, 2025 through April 30, 2026, and an additional eight-month rent abatement for the Expansion Space once it is made available. The Landlord also agreed to a $5 million tenant improvement allowance for the expansion space, and to the extent the full allowance is not used, up to 50% of it may be applied against the Company’s rent obligations.

The foregoing description of the terms of the Lease Amendment is not complete and is qualified in its entirety by reference to the full text of the Lease Amendment. A copy of the Lease Amendment will be filed as an exhibit to the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.
