Item 1.01. Entry into a Material Definitive Agreement.

Effective as of June 30, 2021, Xencor, Inc. (the “Company”) entered into a Lease (the “Lease”), with Angelo Gordon Real Estate, Inc. (the “Landlord”) relating to approximately 129,543 rentable square feet, for laboratory and office space, located at 465 North Halstead Street, Pasadena, California (the “Premises”). The Company intends to move its corporate headquarters to the Premises in the second half of 2022. The term of the Lease will become effective in two phases. The first phase of the Lease term commences on July 1, 2022 and encompasses approximately 83,083 square feet (“Phase 1 Premises”). The second phase of the Lease term commences no later than September 30, 2026 and encompasses an additional approximately 46,460 square feet (“Phase 2 Premises”). The term of the Lease is 13 years from the July 1, 2022 commencement date.  

The Company received delivery of the Premises on July 1, 2021 and is scheduled to complete construction of office, laboratory, and related improvements in 2022. Under the terms of the Lease, the Landlord is providing an improvement allowance up to $17,032,015.00 in connection with the Phase 1 building improvements. The Company is obligated to pay the Landlord an initial base monthly rent of $386,336.95, or $4.65 per square foot for the Phase I Premises. The monthly base rent will increase annually by approximately three percent of the then-current base rent. Upon the rent commencement date for the Phase 2 Premises, the base rent for such additional space will commence at the same per-square foot rate as the then applicable rate for the Phase 1 Premises, increased to reflect the additional space of the Phase 2 Premises and subject to the same rate of annual increases in base rent. The Company is entitled to an additional improvement allowance of up to $3,252,000.00 in connection with building improvements constructed in the Phase 2 Premises. No base rent will be due from July 1, 2022 through October 31, 2022. The Company will also be responsible for its proportional share of operating expenses, tax expenses and utility costs, each as defined in the Lease, associated with the ownership, operation, maintenance, and repair of the Premises, subject to certain exclusions provided in the Lease.

The foregoing description of the material terms of the Lease does not purport to be complete and is subject to, and is qualified in its entirety by, reference to the Lease, a copy of which will be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for the period ended June 30, 2021.
