Amendment Description Historically, the Company has classified receipts from Bitcoin mining revenue as cash flows from operating activities on the Company’s consolidated statements of cash flows.In response to a comment letter received from the SEC in connection with its review of the Original Form 20-F, and following review and consultation with management and upon the recommendation of the Audit and Risk Committee, the Board of Directors of the Company concluded that the Company’s audited consolidated financial statements for the Affected Periods should be amended and restated to classify proceeds from sales of Bitcoin mined as cash flows from investing activities in accordance with IAS 7.16(b) "Statement of Cash Flows" ("IAS 7"). Therefore, the Company’s audited consolidated financial statements for the Affected Periods should no longer be relied upon. Further, any previously furnished or filed reports, earnings releases, investor presentations or similar communications regarding the restatement information for the Affected Periods should also no longer be relied upon. The restatement does not impact the Company’s consolidated statements of profit or loss and other comprehensive income, consolidated statements of financial position, consolidated statements of changes in equity, or cash and cash equivalents at the end of the respective periods for the Affected Periods.
