LEASES

12 Months Ended

Dec. 31, 2024

The Company determines if an arrangement is or contains a lease at contract inception. The Company leases office space, patient service centers, clinical laboratories, warehouses, logistic hubs and equipment primarily through operating leases, with a limited number of finance leases. A right-of-use asset, representing the underlying asset during the lease term, and a lease liability, representing the payment obligation arising from the lease, are recognized on the balance sheet at lease commencement based on the present value of the payment obligation. For operating leases, expense is recognized on a straight-line basis over the lease term. For finance leases, interest expense on the lease liability is recognized using the effective interest method and amortization of the right-of-use asset is recognized on a straight-line basis over the shorter of the estimated useful life of the asset or the lease term. Short-term leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term. For the years ended December 31, 2024, 2023, and 2022, lease expense associated with short-term leases was not material.

The Company primarily uses its collateralized incremental borrowing rate in determining the present value of lease payments as the Company's leases generally do not provide an implicit rate. Such incremental borrowing rates, which take into account interest rates offered to companies that have similar credit ratings to the Company, are determined using a portfolio approach which groups the Company’s leases based on tenor.

The Company has lease agreements with (i) right-of-use asset payments and (ii) non-lease components (i.e., payments related to maintenance fees, utilities, etc.) which have been combined and accounted for as a single lease component.

The Company's leases have remaining terms of less than 1 year to 14 years, some of which include options to extend the leases for up to approximately 20 years. The Company's lease terms may include renewal options that are reasonably certain to be exercised and termination options that are reasonably certain not to be exercised. Certain leases also include options to purchase the leased property.

Certain of the Company's lease agreements include rental payments adjusted periodically for inflation or a market rate which are included in the lease liabilities.
