3. Discontinued Operations

On November 12, 2025, after considering all reasonably available options and a broader strategic reassessment, the Company’s board of directors approved the wind down of the Company’s ClearUP business, which the Company substantially completed prior to the end of 2025. In connection with the wind down of the ClearUP business, the Company incurred approximately $347 thousand in charges during the year ended December 31, 2025, which included $230 thousand for the write-off of inventory and $117 thousand for the write-off of property and equipment. We expect to incur additional related expenditures in the range of approximately $20 thousand to $50 thousand in 2026 for disposal costs on remaining finished goods. The estimates of the charges and costs that we expect to incur, and the timing thereof, are subject to a number of assumptions and actual results may differ materially from those described above. In addition, we may incur other charges or cash expenditures not currently contemplated due to unanticipated events that may occur as a result of, or in connection with, the wind down of the ClearUP business.  During the first two months of 2026 our sales platform remained open and ClearUP units continued to sell while we worked out logistics for shutting down the site.  As all inventory had been written off in 2025, our only costs in the first quarter related to shipping, storage and order fulfilment.  During the second quarter of 2026 we incurred approximately $40 thousand of costs related to refunds to third-party resellers for their remaining unsold inventory.
