AVROBIO Inc

Our corporate headquarters are located in Cambridge, Massachusetts, and encompasses a total of approximately 26,114 square feet of leased office space and laboratory facilities, pursuant to a sub-sublease. We initially entered into the sub-sublease for 13,643 square feet of laboratory space, or the Lab Sublease, in August 2018. The Lab Sublease was set to expire in April 2022. In January 2022, we amended the Lab Sublease to increase the premises to a total of 26,114 square feet and extend the term through April 30, 2023, and we have thereafter agreed to extend the Lab Sublease through April 30, 2024. In June 2020, we entered into a lease agreement for 3,885 square feet of office space located in Toronto, Ontario, Canada, which provided for expiration in June 2025. In October 2022, we subleased the entirety of the Toronto leased office space to a third party for a term extending through June 2025. In October 2023 we agreed with the landlord and subtenant to terminate each of the lease and sublease for the Toronto leased office space effective as of October 31, 2023. We believe that we have office and/or laboratory space sufficient to meet our current needs and that suitable additional space or alternative space will be available to the extent needed on commercially reasonable terms.
