As of June 30, 2026, the Company had an operating lease for an office in Cambridge, Massachusetts (the “Cambridge Lease”), which expires in 2028.

The Company also leased an office in the Borough of Manhattan in New York, New York (the “Manhattan Office”), which was to expire in January 2027, and was subleasing the Manhattan Office to a sublessee. The sublease was to expire in October 2026. On February 16, 2026, the Company entered into a sublease termination agreement with the sublessee of the Manhattan Office effective March 13, 2026. Pursuant to the sublease termination agreement, the sublessee agreed to surrender and vacate the premises in exchange for a termination payment of approximately $60,000, which represented the remaining sublease payments through October 2026. As a result, the Company recognized a gain for the sublease termination of approximately $56,000, which is included in general and administrative expense in the accompanying condensed consolidated statement of operations for the six months ended June 30, 2026.

On February 18, 2026, the Company entered into a lease termination agreement with the lessor of the Manhattan Office effective March 13, 2026. Pursuant to the lease termination agreement, the Company agreed to surrender and vacate the premises in exchange for a termination payment of approximately $72,000 to the lessor.

The lease termination agreement was accounted for as a modification to the Manhattan Office lease rather than as a lease termination because the Company did not contemporaneously terminate the Manhattan Office lease upon the February 18, 2026 modification date and had a continued right-of-use of the facility through March 13, 2026. As a result, the Company remeasured the remaining lease payments, including the $72,000 termination fee, and reduced the lease liability the Company had on its balance sheet at the time of the modification by approximately $26,000 to the present value of the remeasured lease liability of approximately $79,000. For a lease modification that is not accounted for as a separate contract, a lessee recognizes the amount of the remeasured lease liability as an adjustment to the corresponding right-of-use (“ROU”) asset without affecting profit or loss. As a result, the Company reduced the ROU asset by approximately $26,000 to approximately $31,000, which was amortized through March 13, 2026. As of June 30, 2026, there was no lease liability or ROU asset for the Manhattan Office remaining.
