Operating Leases
The Company has an operating lease for office and laboratory space in Boston, Massachusetts (the “Boston Lease”). The Boston Lease commenced in February 2022 with the term set to expire in February 2030. The Boston Lease has rent payments escalating annually, which total $11.1 million in the aggregate. As a result, at the commencement of the Boston Lease the Company recognized a right-of-use (“ROU”) lease asset of $8.0 million with a corresponding lease liability of $8.0 million based on the present value of the minimum rental payments. In addition, the Company will make payments for operating expenses and real estate taxes. In June 2023, the Company secured a letter of credit for the $0.7 million deposit on the Boston Lease, which was reported as restricted cash, noncurrent on the consolidated balance sheets as of December 31, 2025. In April 2026, the letter of credit was amended and reduced to $0.5 million, which was reported as restricted cash, noncurrent on the condensed consolidated balance sheets as of June 30, 2026.
Lease expense for the three and six months ended June 30, 2026 was $0.3 million and $0.7 million, respectively. Lease expense for the three and six months ended June 30, 2025 was $0.3 million and $0.7 million, respectively.
