In August 2021, the Company entered into a lease agreement (the “Waltham Lease”) for approximately 5,000 square feet of office space in Waltham, Massachusetts for the Company’s corporate headquarters. The Waltham Lease has a term of thirty-nine months (“Lease Term”), unless extended or earlier terminated. The Company had the option to extend the Waltham Lease for one additional period of three years. The Lease Term had an initial abatement period, and the initial base rent payable is approximately $18,000 per month following the abatement period. The initial base rent payable will increase by approximately 2% per year over the Lease Term. The Waltham Lease commencement date was September 1, 2021. In January 2024, the Company entered into the First Amendment to the Waltham Lease resulting in the lease expiring on December 31, 2025, and an increase of $1.00 per rentable square foot during the additional lease term. In obtaining this lease extension, the Company no longer has the option to extend the Waltham Lease for one additional period of three years.

In April 2022, the Company entered into a lease agreement (the “Foster City Lease”) for approximately 3,500 square feet of office space in Foster City, California. The Foster City Lease has a term of thirty-nine months, unless extended or earlier terminated. The Company has the option to extend the Foster City Lease for an additional period of one year. The base rent payable under the Foster City Lease is approximately $22,600 per month and will be subject to annual increase of 3% on each anniversary. Following the Company’s Workforce Reduction Plan, the Company terminated all employees in the Foster City office and vacated the premises in

September 2024. As a result, the Company impaired the related right-of-use asset of approximately $0.3 million, and recognized a loss on impairment in its general and administrative operating expenses during the year ended December 31, 2024
