Item 1.01 Entry into a Material Definitive Agreement.

On December 3, 2025, QuantumScape Battery, Inc. (the “Company”), a wholly owned subsidiary of QuantumScape Corporation, entered into a Sublease Agreement (the “Sublease”) with Momentus Inc. (“Sublessee”) for the entire building located at 1762 Automation Parkway, San Jose, California, consisting of approximately 61,100 rentable square feet (the “Premises”). The Premises are outside of the Company’s headquarters and are the subject of a lease agreement by and between the Company and Utah Land & Capital, LLC (the “Master Landlord”), dated as of November 1, 2021, as subsequently amended (the “Master Lease”). This Sublease results in a smaller operational footprint consistent with the Company’s technology licensing focus.

The Sublease term commences on the date the Company obtains the Master Landlord’s consent and delivers the Premises in the requisite condition, and expires on September 30, 2032 concurrently with the expiration date of the Master Lease, unless terminated earlier in accordance with its terms. Under the Sublease, Sublessee will initially pay monthly base rent (“Base Rent”) of $72 thousand through November 30, 2026, escalating annually thereafter, reaching $175.1 thousand for the final period ending September 30, 2032. The Company expects to receive a total of approximately $11.5 million, after abatements, as Base Rent over the term of the Sublease.

Base Rent is subject to certain abatements through March 31, 2026. Sublessee is also responsible for additional rent obligations, operating expenses, taxes, and insurance related to the Premises, subject to the terms and conditions of the Master Lease. The Sublease includes customary provisions for agreements of this type, including security deposit, prepaid Base Rent, indemnities, maintenance obligations, and restrictions on assignment and subletting. The Sublease is subject to the Master Landlord’s written consent.

The foregoing description of the Sublease does not purport to be complete and is qualified in its entirety by reference to the full text of the Sublease, which will be filed as an exhibit to the Company’s annual report on Form 10-K for the fiscal year ending December 31, 2025.
