The Company identified indicators of impairment of its mining equipment and mining infrastructure asset groups during the three months ended March 31, 2026, including declines in bitcoin prices, declines in bitcoin hashprice, and significant decreases in secondary market values for digital asset mining equipment. In accordance with ASC Topic 360-10, the Company performed a recoverability assessment of its mining-related asset groups. The undiscounted future cash flows for each asset group was less than its carrying amount, indicating the assets were not recoverable.

The Company measured the fair value of its mining equipment using a market approach based on observable secondary market pricing data for similar assets, classified as Level 2 within the fair value hierarchy. The Company measured the fair value of its mining infrastructure assets using an income approach based on a discounted cash flow analysis reflecting the estimated future cash flows a market participant would expect from operating the assets as mining hosting facilities, classified as Level 3 within the fair value hierarchy. Refer to Note 9 — Fair Value Measurements for the significant unobservable inputs used in the Level 3 measurement.

Assets Held for Sale

During the three months ended June 30, 2026, the Company committed to a plan to sell certain undeployed mining equipment and certain electrical equipment that the Company no longer intends to use in its operations. The assets met the criteria for held-for-sale classification under ASC 360-10-45-9, and the Company expects the sales to be completed within one year. Upon classification, depreciation ceased and the assets were remeasured to fair value less cost to sell; see Note 9 — Fair Value Measurements. The remeasurement resulted in a loss of $19.5 million, recognized within “Loss on remeasurement of assets held for sale” on the condensed consolidated statement of operations for the three and six months ended June 30, 2026. The remaining carrying value of $13.8 million is included within “Customer funding receivable and other current assets” on the condensed consolidated balance sheets as of June 30, 2026.
