Operating Leases
In July 2020, the Company entered into a seven-year agreement with an option to extend for five additional years to lease two floors totaling approximately 25,578 square feet of office space for its principal office, which is located in Cambridge, MA. The lease on the first floor commenced on August 1, 2020 and the lease on the second floor commenced March 9, 2021. The Company recognized the respective lease balances on the consolidated balance sheets when the lease of each floor commenced. Under the terms of the lease, the Company was required to issue a $1,168 letter of credit as security for the lease, which was reduced to $779 in August 2023 pursuant to the terms of the lease agreement. On December 12, 2022, the Company entered into a sublease for one floor of its Cambridge, Massachusetts office space. The sublease terminates on August 31, 2028, which is also the date on which the Company's lease terminates. Further, on December 5, 2025, the Company entered into a sublease for the remaining floor of its Cambridge, Massachusetts office space. The sublease terminates on August 31, 2028, which is also the date on which the Company's lease terminates. Sublease income is recognized on a straight-line basis over the term of the sublease agreement. The Company was not relieved of its primary obligation under the Cambridge office lease as a result of the subleases. There was no impairment recognized as a result of the sublease executed in December 2022. As part of the Company’s evaluation of the December 2025 sublease, it was determined that the estimated undiscounted sublease income exceeded the net book value of the related long-term assets, which includes right-of-use assets and property and equipment associated with the subleased space. Accordingly, the Company recorded an impairment charge of $2,025 related to the right-of-use asset and an impairment charge of $580 related to the associated property and equipment.
In December 2020, the Company entered into an eleven-year agreement to lease approximately 18,120 square feet of office and laboratory space in New York, NY. The Company has an option to extend the lease for five additional years. The lease commenced August 26, 2021 and the related lease balance was recognized on the consolidated balance sheet. Additionally, on June 19, 2024, the Company entered into a sublease for its office and laboratory space in New York, NY. The sublease terminates on June 30, 2026, with the option to extend to June 30, 2027. Sublease income is recognized on a straight-line basis over the term of the sublease agreement. The Company was not relieved of its primary obligation under the New York lease as a result of the sublease. In December 2025, the subtenant did not exercise its option to the sublease, accordingly it will terminate on June 30, 2026. As part of the Company’s evaluation of the termination of the sublease, it was determined that the undiscounted cash flows projected from an anticipated future sublease exceeded the net book value of the related long-term assets, which includes right-of-use assets and property and equipment associated with the subleased space. Accordingly, the Company recorded an impairment charge of $4,626 related to the right-of-use asset and an impairment charge of $117 related to the associated property and equipment.
