Kodiak Sciences Inc. Notes to Consolidated Financial Statements (in thousands, except share and per share data) 97 Ursus Facility In August 2020, the Company and its wholly owned subsidiary Kodiak Sciences GmbH entered into a manufacturing agreement with Lonza Ltd (“Lonza”) for the clinical and commercial supply of the Company’s antibody biopolymer conjugate drug substance which included a custom-built manufacturing facility. The manufacturing agreement has an initial term of 8 years, and the Company has the right to extend the term up to a total of 16 years. The Company and Lonza each have the ability to terminate this agreement upon the occurrence of certain events. In April 2021, the agreement was amended to provide for greater manufacturing flexibility, to define a comprehensive mandate as an antibody biopolymer conjugates manufacturing facility to be used for the Company’s antibody biopolymer conjugates pipeline, at clinical as well as commercial scales, across a broad capacity range under the tight quality controls required for ophthalmology and retinal medicines, and to allow for future process and equipment changes as needed. The Company concluded that this agreement contained an embedded lease as the custom-built manufacturing suite would be dedicated for the Company’s use. On January 31, 2023, the custom-built manufacturing suite was commissioned as a cGMP facility. The consideration was allocated to lease and non-lease components as this agreement contained a significant service component (manufacturing services). Under ASC 842, the Company classified the lease portion as an operating lease and recorded a right-of-use asset and lease liability on the lease commencement date. Fixed assets of $81.7 million, in leasehold improvements and machinery and equipment, were placed in service and capitalized as of January 31, 2023.
