Other Finance Lease Considerations In the fourth quarter of 2024, the Company provided notice to the lessor of one of its leased U.S. manufacturing facilities of its intent to exercise the $11.5 million purchase option included in the lease agreement. The Company remeasured the corresponding lease liability, adjusted the right-of-use asset, and reassessed the lease classification, resulting in a change in classification from an operating lease to a finance lease. As of December 31, 2024, the related finance lease right-of-use asset was $11.3 million and the finance lease liability was $11.5 million. The associated impact on the Company’s Consolidated Statement of Operations for the year ended December 31, 2024 was insignificant. The weighted average discount rate was 4.9%. The purchase was completed on February 10, 2025.
