Riot Blockchain, Inc.
(Name of Registrant as Specified in Charter)

has caused this notification to be signed on its behalf by the undersigned hereunto duly authorized.


Date:  August 16, 2021  
   By: /s/ Jeffrey G. McGonegal
    Jeffrey G. McGonegal
(Principal Financial and Accounting Officer)









On May 26, 2021, the Registrant completed its acquisition of its subsidiary, Whinstone US, Inc., as previously reported on the Registrant’s Current Report on Form 8-K filed with the Commission on that date. The Registrant subsequently amended this Current Report to include certain required financial disclosures pertaining to the business and operations of Whinstone US, Inc., by an amendment on Form 8-K/A filed with the Commission on August 12, 2021. As of the date of this filing, the integration of Whinstone US, Inc. into the Registrant’s financial statements, including its results of operations, has not been completed.


As a result of its acquisition of Whinstone US, Inc. on May 26, 2021, the Registrant expects that a significant change to its results of operations and consolidated statements of cash flows and shareholder equity will be reflected in the Quarterly Report, beginning on the date the acquisition was completed, as compared to the corresponding periods of the prior fiscal year. However, because its unaudited interim financial statements for the quarterly period ended June 30, 2021 are not finally completed as of the date of this filing, the Registrant is not able to quantify the anticipated changes in its results of operations at this time.
