Leases
The Company’s leases primarily consist of office and lab space, and equipment for use in its operations. Its leases generally have lease agreements which expire in 2026 to 2036, some with the option to extend. The Company includes extension options that are reasonably certain to be exercised as part of the lease terms. As of December 31, 2025, none of the Company’s lease terms included the extension option as the Company has determined that it is unlikely to exercise the extension option.
Operating Leases
The Company’s primary operating lease arrangements include leased properties for its corporate office and headquarters located in Stamford, Connecticut, its primary operating laboratory located in Gaithersburg, Maryland, a corporate office in Oakland, California, and a satellite meeting space located in New York City. The lease agreements for these properties expire in 2034, 2031, 2029, and 2026, respectively.
The Company’s operating leases also include laboratories in Branford, Connecticut and Stamford, Connecticut have ceased operations as part of the Company’s announced exits in 2022 from reproductive health and somatic tumor testing. The lease agreements for these properties expire in 2030 and 2036, respectively. These facilities as well as a portion of its headquarters located in Stamford, Connecticut are actively being marketed for sublet; however, the outstanding lease obligations remain obligations. At inception of the lease for the laboratory in Stamford, Connecticut, the value of the land was determined to be more than 25% of the total value and therefore the building is accounted for as a finance lease and the land as an operating lease.
Finance Leases
In addition to its leased laboratory building in Stamford, Connecticut noted above, the Company routinely enters into various finance lease agreements to obtain laboratory equipment that contain bargain purchase commitments at the end of the lease term. The leases are secured by the underlying equipment.
