Financial results are from the unaudited Form 10-Q for the three months ended March 31, 2026. The quarter included a $224.1 million loss from the change in fair value of Bitcoin and a $38.8 million loss related to Bitcoin collateral. Local refresh methodology note — September 29, 2026 (approved Batch 1 and later manifest; not a blanket verification date): HOLD — methodology review required for the latest balance. Retain 12,205 attributable/unencumbered BTC at June 30 as historical only. This excludes 1,719 BTC receivable from transferred control. The separate August 31 headline (and btc_total_reported) is 13,703, including 3,951 jointly described as collateral or receivables; ownership split is unresolved. Neither 13,703 nor the conditional 9,752 replaces June eligible BTC. The primary-field change is not a verified sale reconciliation. Under the later approved manifest, directory status is Needs Review and qualification is pending; the historical balance is not counted. Financial mapping: Revenue: "Bitcoin mining revenue, net". Net result: "Net (loss) income", consolidated. The quarter common-shareholder loss equals consolidated loss, but nine-month attribution differs.
