MoonLake Immunotherapeutics MLTX Portugal — Number of operating leases

MoonLake does not have any finance leases. As of March 31, 2026, the Company has five operating leases related to the office spaces located in (i) Dorfstrasse 29, 6300, Zug, Switzerland (comprised of two leases), (ii) 95 Regent Street, CB2 1AW, Cambridge, England, United Kingdom, and (iii) Rua Manuel Pinto de Azevedo 860, 4150-335, Porto, Portugal (comprised of two leases). The operating leases are recognized over a straight-line basis over the lease term commencing on the date the Company has the right to use the leased property. Right-of-use assets and lease liabilities are measured at the lease commencement date based on the present value of the remaining lease payments over the lease term, determined using the discount rate for the lease at the commencement date. Because the rate implicit in the leases is not readily determinable, the Company uses the incremental borrowing rate as the discount rate, which approximates the interest rate at which the Company could borrow on a collateralized basis with similar terms and payments and in similar economic environments.
