Construction in progress consisted primarily of production and other equipment that have not been placed in service as of December 31, 2025 and 2024.
Depreciation and amortization expense was $4.4 million and $3.8 million during the years ended December 31, 2025 and 2024, respectively.
During the year ended December 31, 2025, we recorded a $4.7 million impairment loss related to construction-in-progress assets for our manufacturing facility in Brighton, Colorado, in connection with our decision to terminate the lease. Please refer to Note 9. Leases for our discussion of the methodology and significant inputs used to determine the estimated fair value. In addition, we recorded a $3.5 million loss related to the retirement of production equipment at our Fremont, California facility that was no longer expected to generate future economic benefit. During the year ended December 31, 2024, we recognized a $1.9 million loss associated with the retirement of certain production equipment at our Fremont facility due to a change in operating plans. These impairment and retirement losses are presented within “Impairment and other” in our Consolidated Statements of Operations.
