Item 1.01Entry into a Material Definitive Agreement.

On November 13, 2020, Constellation Pharmaceuticals, Inc. (the “Company”) entered into a lease (the “New Lease”) with ARE-MA Region No. 75, LLC, a Delaware limited liability company (the “Landlord”), effective as of November 13, 2020, pursuant to which the Company will lease approximately 79,155 square feet of office and laboratory space located at 100 Talcott Street in Watertown, Massachusetts (the “New Premises”).

The date on which the Company will become responsible for paying rent under the New Lease will be December 24, 2021 (the “Commencement Date”). The New Lease will have a ten-year term. The New Lease also provides the Company with an option to extend the New Lease for an additional five-year term. The Company’s monthly base rent for the New Premises will be $467,978.66, and will increase on each anniversary of the Commencement Date by approximately 3% per annum, up to a maximum monthly base rent of $610,606.01 during the ten-year term. The Company’s expected contractual obligation for base rent over this term is approximately $64.4 million.

The Company will post a customary letter of credit in the amount of approximately $2.8 million as a security deposit pursuant to the New Lease. The Company expects the New Premises to be ready for occupancy in late 2021 and intends to relocate its corporate headquarters to the New Premises at such time.

On November 13, 2020, the Company entered into a Sixth Amendment to Lease (the “Lease Amendment”) with ARE-MA Region No. 38, LLC (the “Existing Landlord”), amending the Lease Agreement, dated as of February 5, 2010, by and between the Company and the Existing Landlord, as amended (the “Existing Lease”). The Lease Amendment provides that the Existing Lease will terminate sixty calendar days from the Commencement Date for the New Lease.

The foregoing summaries of the principal terms of the New Lease and the Lease Agreement do not purport to be complete and are qualified in their entirety by reference to the complete text of the New Lease and the Lease Amendment, copies of which will be filed as an exhibit to the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.


Pursuant to the requirements of the Securities Exchange Act of 1934, as amended, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
