NOVAVAX INC

As of December 31, 2025, we lease and own approximately 192,000 square feet of office and other space in the U.S., including our corporate headquarters at 21 Firstfield, Gaithersburg, Maryland, and approximately 60,000 in various foreign locations. We use this space for our services and support, commercial, research and development, manufacturing, and administrative personnel. Although we believe that our facilities are suitable and adequate for our present needs, the Company’s management continues to review and assess real property requirements that may be necessary to address our current business plan.

As of December 31, 2025, we classified the property located at 700 Quince Orchard Road, Gaithersburg, Maryland (“700QO”) as held for sale, in accordance with our accounting policy described in Note 2 to our consolidated financial statements. The facility served as our corporate headquarters until we relocated to 21 Firstfield, Gaithersburg, Maryland, during 2025. Although the lease for 700QO remained effective as of December 31, 2025, we completed the assignment of our leasehold interest in January 2026, resulting in the termination of the lease.
