Nkarta, Inc.

Our facilities are located at three leased sites. The first site, located at 6000 Shoreline Court, South San Francisco, California, consists of approximately 36,544 square feet of office and laboratory space and is primarily used for manufacturing activities. Of this office and laboratory space, approximately 14,697 square feet was subleased as of December 31, 2024. Our lease covering multiple suites at this site expires in July 2030, with certain suites expiring in July 2025, and our subleases expire in November 2027 and July 2030. The second site, located at 750 Gateway Boulevard, South San Francisco, California, consists of 510 square feet of vivarium and laboratory space, and is primarily used for preclinical research. Our agreement that provides for our use of these vivarium and laboratory spaces expires in December 2025. The third site, located at 1150 Veterans Boulevard, South San Francisco, California, consists of 88,000 square feet of office and laboratory space and is primarily used for research, clinical, manufacturing and corporate activities. This lease expires in 2034. As a result of moving our main offices and research activities to the Veterans location in 2023, we vacated certain suites at the 6000 Shoreline Court location. We sublease some of these suites while still maintaining sufficient office and laboratory space to allow our team to continue to develop our proprietary programs. We believe that these facilities are sufficient to meet our current needs.
