13. Leases

The Company’s primary operating lease obligations consist of leases for office space and manufacturing facilities in Massachusetts and Connecticut.

The Company has leases for office space and certain equipment. Some of the leases include options to extend the lease for up to ten years and these options were not included for the purpose of determining the right-of-use assets and associated lease liabilities as the Company determined that the renewal of these leases is not reasonably certain. The leases do not include any restrictions or covenants that had to be accounted for under the lease guidance. All of the leases recorded on the consolidated balance sheets as ROU assets are operating leases.

In July 2025, the Company acquired KAF and entered into an agreement to lease the approximately 11,500 rentable square feet facility in Stamford, Connecticut. The lease commenced in December 2025 for a term of 25 months with total lease costs of approximately $0.4 million.

In June 2025, the Company entered into a new operating lease agreement in Burlington, Massachusetts. The new lease is for approximately 13,000 rentable square feet and commenced in June 2025 for a term of 50 months with total lease costs of approximately $1.9 million. The Company abandoned its facility in Boston, Massachusetts to relocate the Company’s headquarters and research and development activities to the new Burlington location. See Note 9, Restructuring.

In February 2025, the Company entered into a new operating lease agreement in Massachusetts to relocate the machine shop from the Company’s headquarters to a lower cost location. The new lease is for approximately 3,500 rentable square feet and commenced in March 2025 for a term of 60 months with total lease costs of approximately $0.2 million.

For additional information, read Note 16, Leases, to the consolidated financial statements in the Company’s Form 10-K for the year ended December 31, 2025.

The interest rate implicit in lease contracts is typically not readily determinable and as such, the Company uses its incremental borrowing rate based on information available at the lease commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal to the lease payments in a similar economic environment.
