AbCellera Biologics Inc.

Our corporate headquarters and research and development facilities are located in Vancouver, British Columbia, where we lease approximately 260,000 square feet of space under leases expiring between 2026 and 2037. Through our Dayhu joint venture, we completed our new, dedicated corporate headquarters in 2024, that provides us 167,000 square feet of laboratory and office space. In December 2025, we obtained financing secured against this laboratory and office space as further described in Note 8 of our annual consolidated financial statements for the year ended December 31, 2025. Through our Beedie joint venture, we are nearing the completion of construction of 220,000 square feet of additional lab and office space. The Dayhu and Beedie spaces are under lease which expire starting in 2037 and 2045, respectively, with further renewal options. Once complete, we intend to assign or fully sublease theoffice and laboratory space constructed through the Beedie joint venture. Further, our 130,000 square feet clinical manufacturing (GMP) facility built on land we purchased in 2022 in Vancouver, was completed in late 2025.

AbCellera Australia Pty. Ltd., our wholly owned subsidiary, occupies approximately 40,000 square feet of office and laboratory space in Sydney, Australia, with a lease that expires in 2031. We also lease an additional 10,000 square feet of office and laboratory space across the other jurisdictions in which we operate, and we believe our facilities are adequate and suitable for our current needs and that should it be needed, suitable additional or alternative space will be available to accommodate our operations.
