Miner contributions to Bear Facility and Chief Facility In October 2022, the Company contributed approximately 6,500 miners to the Bear Facility and the Chief Facility. While the final quantities of miners going to each respective site, and therefore the relative pricing as between the two sites, is still being finalized, the estimated fair value of the relevant miners was lower than the cost paid by the Company to purchase them; therefore, the Company expects to record a loss related to the contribution of these miners of approximately $15 million.

The Supplementary Agreement establishes new fixed and floating price terms for remaining purchases of M30S, M30S+ and M30S++ miners and the Company will not be obligated to send any further money to SuperAcme. In connection with the Amended SuperAcme Agreement, SuperAcme has delivered 17,833 miners to date, at an aggregate value of approximately $53.6 million, and the Company has paid aggregate advance payments of $101.8 million.

Payments on behalf of Bitfury After September 30, 2022, but before the issuance of these unaudited condensed consolidated financial statements, the Company made payments totaling approximately $2.1 million directly to Paradigm in place of Bitfury USA, in respect of manufacturing services for BBACs. The Company’s payment obligations to Bitfury USA under the Master Services and Supply Agreement were also reduced by $2.1 million related to these payments to Paradigm. Luminant Power Agreement On October 26, 2022, the Company received a letter from Luminant, disputing: (i) the payments of $1.7 million that Luminant had made to the Company under the Luminant Power Agreement for the electricity sold in the ERCOT market during July 2022 and August 2022 and (ii) the payment of $5.1 million made to the Company by Luminant in September 2022 in consideration for the modification to the ramp up schedule pursuant to the August Amendment to the Luminant Power Agreement. The Company received and recorded $1.7 million as part of the change in fair value of derivative asset in the condensed consolidated statements of operations for the three and nine months ended September 30, 2022. The Company received and recorded $5.1 million as a reduction to the derivative asset on the condensed consolidated balance sheet during the three months ended September 30, 2022. The Company has not received payment from Luminant for electricity sold in the ERCOT market in September 2022 and October 2022. The Company wholly disputes the claims made by Luminant and has been engaged in discussions with Luminant in an attempt to reach a mutually agreeable solution and resolve disagreements between the parties regarding these payments and whether the commencement of Luminant’s obligations under the Luminant Power Agreement should be tied to ERCOT’s interconnection approval. At this time the Company’s management does not know how or when this dispute will be resolved. On November 8, 2022, the Company also received a letter from Luminant requesting the Company deposit to Luminant the remaining half of the Independent Collateral Amount under the Luminant Power Agreement. The Company expects to deliver to Luminant the remaining half of the Independent Collateral Amount before the end of November 2022.
