LEASES

On November 19, 2021, the Company entered into a 15-year lease for approximately 144,000 square feet of office and research and development laboratory space in San Diego, California. This facility replaces the Company’s current office and research facility located in San Diego, California. The increased capacity of this new facility compared to the Company’s current research facility in San Diego will accommodate increased personnel for its expanding pipeline of current and future drug candidates. The lease payments which began on April 19, 2023, the rent commencement date, will be approximately $119.0 million over the initial 15-year term. The Company also estimates payments for operating expenses to be approximately $3.0 million for the first year of the lease, and these payments will continue throughout the initial 15-year term. The Company expects to pay approximately $32.0 million for leasehold improvements, net of tenant improvement allowances. Pursuant to the lease, within twelve months of the expiration of the initial 15-year term, the Company has the option to extend the lease for up to one additional ten-year term, with certain annual increases in base rent.
