7. Leases

The Company leases real estate, including laboratory, manufacturing and office space, and certain equipment. The Company’s two real estate leases in effect as of December 31, 2025 have remaining lease terms of approximately 1.5 years and 2.5 years, respectively. The Company’s equipment leases in effect as of December 31, 2025 have remaining lease terms ranging from approximately 0.9 to 1.3 years. All of the Company’s leases qualify as operating leases.

The lease for the Company’s 20,445 square feet of manufacturing space located at 36 Crosby Drive in Bedford, Massachusetts commenced on June 30, 2018. On October 18, 2022, the Company exercised its option to extend the lease agreement by an additional five-year term, resulting in a new expiration date of July 31, 2028. Under the terms of the existing lease, rent for the five-year extension period was based on the current fair market rent for comparable space in

the building and in other similar buildings in the same rental market as of August 1, 2023, the commencement date of the additional five-year term. The Company estimated the prevailing market rental rates at the time when the Company exercised the renewal option and included these in the remeasurement of the operating lease asset and the lease liability. This resulted in an increase of the operating lease assets and operating lease liabilities of $4,284 as of the remeasurement date. As this is an estimate for variable payments that depend on an index or a rate, the Company has not remeasured the payments for the five-year renewal period as of the commencement date of the five-year extension term. On June 30, 2023, the Company and the landlord executed an amendment to this lease, formally extending the term of the lease through July 31, 2028. This lease does not include any additional renewal options.

The lease for the Company’s approximately 70,712 square feet of general office, research and development and manufacturing space located at 15 Crosby Drive in Bedford, Massachusetts commenced on February 1, 2017 and will expire on July 31, 2027. The Company has the option to extend the lease for two additional periods of five years each by delivering written notice of the exercise not earlier than fifteen months nor later than 12 months before expiration of the original term.

The lease for the Company’s approximately 30,036 square feet of office space located at 24 Crosby Drive in Bedford, Massachusetts commenced on April 18, 2019 and terminated on March 31, 2024.

Certain equipment leases include options to renew on a month-by-month basis, at the sole discretion of the Company.

About Leases Disclosures

Lease disclosures under ASC 842 provide a comprehensive view of a company's leased asset portfolio, including the split between operating and finance leases, discount rates used to present-value future payments, and the maturity schedule of lease obligations. This section reveals a significant source of off-balance-sheet commitments that were largely hidden before the current standard.

Key signals: the weighted-average discount rate affects the size of recorded lease liabilities — a higher rate reduces the reported obligation, so compare the chosen rate against the company's incremental borrowing rate. The operating versus finance lease mix affects both EBITDA and operating income presentation. Watch the maturity table for concentration risk: large payment cliffs in specific years may create cash flow pressure. Variable lease payments excluded from the liability measurement represent real obligations that do not appear on the balance sheet. Compare total lease costs against prior-year operating lease expense to assess the true economic burden.
