Amendment Description On March 16, 2022, Riot Blockchain, Inc. (“Riot Blockchain,” “Riot,” the “Company,” “we,” “us,” “our,” or the “Registrant”) filed its Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (the “Original Form 10-K”) with the U.S. Securities and Exchange Commission (the “SEC”) and filed Amendment No. 1 (“Amendment No. 1”) to the Original Form 10-K on May 2, 2022 to include certain disclosures under Part III, Items 10, 11, 12, 13 and 14 of Form 10-K in reliance on General Instruction G(3) to Form 10-K.We are filing this Amendment to the Original Form 10-K (this “Amendment No. 2”) to correct an error in the content of Marcum LLP’s (“Marcum”) Report Of Independent Registered Public Accounting Firm On Internal Control Over Financial Reporting (the “ICFR Opinion”). The ICFR Opinion in the Original Form 10-K inadvertently omitted an explanatory paragraph which should have described the exclusion of Whinstone US, Inc. and Ferrie Franzmann Industries, LLC (d/b/a ESS Metron) from Marcum’s audit of internal control over financial reporting. An ICFR Opinion with the explanatory paragraph is included in this Amendment No. 2.Additionally, the Company’s Quarterly Report for the three and nine months ended September 30, 2022, on Form 10-Q filed on November 7, 2022, revised amounts presented within the Original Form 10-K for an error that was considered immaterial to all prior annual and interim financial statements. This Amendment No.2 has been updated to reflect all revised amounts presented herein, is more fully described in Note 3 of the notes to the consolidated financial statements included herein.Except as described above, this Amendment No. 2 does not otherwise change or update any of the disclosures set forth in the Original Form 10-K, and, except as expressly stated herein, does not reflect events occurring after the filing of the Original Form 10-K. This Amendment No. 2 modifies and amends the Original Form 10-K and should be read in conjunction with the Original Form 10-K and Amendment No. 1. References to “this Annual Report” contained in this Amendment No. 2 refer to the Original Form 10-K, as modified and amended by Amendment No. 1 and this Amendment No. 2. Capitalized terms not otherwise defined in this Amendment No. 2 have the meanings given to them in the Original Form 10-K.For a more detailed discussion of our At-the-Market Equity Offerings, see Note 12, “Stockholders’ Equity”, to our Consolidated Financial Statements for the fiscal years ended December 31, 2021, 2020 and 2019, beginning on page F-37 of this Annual Report on Form 10-K/A.
