Item 1.01 Entry into a Material Definitive Agreement.
On January 8, 2026, TransMedics Group, Inc. (the “Company”) entered into a lease agreement (the “Lease”) with BioMed Realty (the “Landlord”) for the lease of approximately 498,286 square feet of space located at 188 Assembly Park Drive, Somerville, MA 02145 (the “Premises”) for the Company’s principal executive offices and for research and development, laboratory, manufacturing and assembly, vivarium, office and related uses. The commencement date of the Lease is January 8, 2026 (the “Delivery Date”). The Premises is expected to serve as the Company’s new headquarters beginning on or before January 1, 2028, replacing its existing headquarters at 200 Minuteman Road, Andover, Massachusetts 01810. Base rent accrues on the latter of: (a) January 1, 2028, and (b) the date that is twenty-four (24) months after term commencement date (but in no event later than February 1, 2028) (the “Rent Commencement Date”). The Lease will expire one hundred ninety-two (192) months from the Rent Commencement Date, unless earlier terminated (the “Initial Term”).
The annual base rent under the Lease will initially be approximately $23.9 million and will be subject to a 2% annual increase for each remaining year of the Initial Term. The Company will also be responsible for a pro rata share of the payment of additional rent to cover the Company’s share of the annual operating and tax expenses for the Premises, with the Company’s share estimated to be approximately 100%. The Company holds two consecutive options to extend the Initial Term for additional periods of ten years each, exercisable by written notice delivered not less than 18 months prior to the expiration of the then-current term and subject to customary conditions, including that no default then exists. The Company also holds an option to extend the Lease term for a period of six months, exercisable by written notice delivered not less than 18 months prior to the expiration of the then-current term and subject to customary conditions, including that no default then exists.
The Company has delivered a security deposit to the Landlord in the form of a letter of credit for approximately $18 million, which may be drawn down by the Landlord to be applied for certain purposes upon the Company’s breach of certain provisions under the Lease. The Lease also contains customary provisions allowing the Landlord to terminate the Lease if the Company fails to remedy a breach of any of its obligations within specified time periods, or upon bankruptcy or insolvency of the Company.
The foregoing description of the Lease does not purport to be complete and is qualified in its entirety by reference to the full text of the Lease, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.
Item 8.01 Other Events
On January 8, 2026, the Company acquired two parcels adjacent to the Premises in Somerville, Massachusetts from BRE-BMR Assembly Innovation I LLC and BRE-BMR Middlesex LLC, respectively. The purchase price for each property was $15.0 million, plus related costs, title company expenses, and tax payments.
