Depreciation and amortization expense related to property, plant and equipment, net, was $5.4 million and $3.4 million for the three months ended March 31, 2024 and 2023, respectively.

During the three months ended June 30, 2023, as a result of a decline in expected future cash flows related to a certain asset group, the Company determined certain impairment triggers had occurred. The Company reviewed revised undiscounted cash flows that were estimated to be generated by the asset group as of June 30, 2023. Based on the undiscounted cash flow analysis, the Company determined that the asset group had net carrying values that exceeded their estimated undiscounted future cash flows. The Company then estimated the fair value of the asset group based on their discounted cash flows. The carrying value exceeded the fair value and as a result, the Company recorded a noncash impairment of $6.0 million for the six months ended June 30, 2023 in cost of goods sold in the consolidated statements of operations.

On January 8, 2024, the Company entered into an agreement with Perspective Therapeutics, Inc. (“Perspective”) to transfer the sublease for the property at 110 Clyde Rd, Somerset, New Jersey as well as sell the associated assets at the Somerset facility for $8.0 million. The transfer of the lease and completion of the asset sale occurred on March 1, 2024. The sale of assets resulted in a derecognition to the right-of-use asset of $0.4 million, the lease liability of $0.4 million and remaining property, plant and equipment of $0.8 million. The Company also incurred commission expense of $1.0 million related to the transaction. The Company recorded a gain of $6.3 million for the three months ended March 31, 2024 within operating income.

See Note 19, “Acquisition of Assets” for further discussion of the Perspective acquisition.

Long-Lived Assets Held for Sale

During the first quarter of 2023, the Company committed to a plan to sell a portion of its land and buildings associated with its Billerica, Massachusetts campus. Effective March 16, 2023, the Company entered into a purchase and sale agreement (the “P&S”) with a prospective buyer. The assets were classified as held for sale and comprised entirely of property, plant and equipment, net. The Company determined that the fair value of the net assets being sold exceeded the carrying value as of March 31, 2024. The purchase price for the campus sale is $10.0 million in cash. The transaction is expected to close during the second quarter of 2024.
