Note 5 – Property, Plant and Equipment, Net and Held for Sale, and Asset Impairment

In June 2024, the Company concluded it had a triggering event requiring assessment of impairment for certain leasehold improvements and the related right-of-use asset. The Company assessed the carrying value of the asset group consisting of the leasehold improvements and right-of-use asset in accordance with ASC 360, given the significant changes to the Company’s operations, operating cash and the repurchase of equipment. The assessment of the recoverability of the asset group concluded that there was impairment on the carrying value of the asset group of approximately $2.6 million, which was allocated on a pro rata basis using the relative carrying amounts of the assets. Approximately $2.2 million of the

impairment loss was allocated to the leasehold improvements, with the remaining $0.4 million allocated to the right-of-use asset.

​

In February 2025, the Company terminated the lease of its Plantation Street Facility. The remaining lease liability of approximately $0.8 million was reversed, and the remaining leasehold improvements of approximately $0.3 million and right of use assets of approximately $0.1 million were written off, resulting in a net gain of $0.4 million recorded in research and development expense in the Statements of Operations.

​

In conjunction with the termination of the lease, the Company also completed the sale of the remaining equipment for approximately $1.2 million, which had been classified as held for sale on the Balance Sheet at December 31, 2024.
