Artiva Biotherapeutics, Inc.

Our principal office is located at 5505 Morehouse Drive, Suite 100, San Diego, California 92121, where we lease 51,621 square feet of space to house our principal office, research and process development laboratories and a cGMP manufacturing center to support our pipeline development and clinical trial supply. This lease will expire in 2029, subject to our option to an additional five-year term. We also have a lease agreement for an additional 13,405 square feet of office space in San Diego, California. We lease this space under a lease that terminates in June 2025. In addition, we have entered into a temporary license agreement for our occupation and use of an additional 11,960 square feet of office and laboratory space in San Diego, California. We believe that these facilities will be adequate for our near-term needs. If required, we believe that suitable additional or alternative space would be available in the future on commercially reasonable terms.
