At the inception of an arrangement, the Company determines if an arrangement is, or contains, a lease based on facts and circumstances present in that arrangement. Lease classifications, recognition, and measurement are then determined at the lease commencement date. The Company’s operating lease right-of-use (“ROU”) assets and operating lease liabilities include primarily leases for office and warehouse spaces used to conduct our business. Finance leases primarily consist of lab, processing and transport equipment used by our facilities’ operations. The components of lease cost for the Company’s leases for the three and nine months ended September 30, 2025, and 2024 were as follows (in thousands): Schedule of Components of Lease Cost
