Our corporate headquarters are located in South San Francisco, California, where we lease and occupy office and laboratory space.

In June 2023, we entered into a lease agreement for approximately 44,000 square feet of laboratory and office facilities at 5000 Shoreline Court, South San Francisco, California. The lease term is 120 months, and we have an option to extend the lease term for a total of two consecutive five-year periods. The lease commenced in August 2024.

In May 2024, we amended our 5000 Shoreline Court facility lease agreement to expand the size of the original premises by adding approximately 11,321 rentable square feet of additional space. The amendment to the lease term commenced in January 2025. Our lease at 7000 Shoreline Court, South San Francisco, California, expired in September 2024.

In November 2023, we entered into a lease agreement for approximately 5,700 square feet of space at 11710 El Camino Real, San Diego, California for corporate office space. The lease commenced in December 2023 and expires in March 2028. We have an option to renew the lease for three years.

We believe our existing facilities are sufficient for our needs for the foreseeable future. To meet the future needs of our business, we may lease additional or alternate space, and we believe suitable additional or alternative space will be available in the future on commercially reasonable terms.
