EXPLANATORY NOTE
Effective May 18, 2023, the Audit Committee of the Board of Directors of Riot Platforms, Inc. (the “Audit Committee” and the “Company” or “Riot”, respectively) notified Marcum LLP (“Marcum”) that Marcum was dismissed as the Company’s independent registered public accounting firm, not as a result of any disagreement on any matter of accounting principles or practices, financial statement disclosure, or audit scope or procedure. As of May 18, 2023, the Audit Committee appointed Deloitte & Touche (“Deloitte”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2023, effective immediately. The Company filed a Current Report on Form 8-K with the U.S. Securities and Exchange Commission (the “SEC”) reporting this change on May 22, 2023.
This Amendment No. 1 to our Definitive Proxy Statement (“Amendment No. 1”) is being filed with the SEC to amend Proposal No. 2 of our original Definitive Proxy Statement, as filed with the SEC on May 1, 2023, (“Proposal No. 2”) to reflect the substitution of Deloitte and our submission for ratification by the Company’s stockholders of such appointment. This Amendment No. 1 amends only those items set forth or described below, and all other items in the Proxy Statement are incorporated herein by reference without changes.
CHANGES TO PROXY STATEMENT
1. All references to Marcum LLP or Marcum in the “Notice of 2023 Annual General Meeting of Stockholders” and the Proxy Statement are amended to read “Deloitte & Touche” or “Deloitte” as appropriate or unless otherwise noted.
2. Proposal No. 2 in the Proxy Statement is amended in its entirety to read as follows:
PROPOSAL NO. 2 – RATIFICATION OF AUDITOR APPOINTMENT
We are asking our stockholders to ratify the appointment by our Audit Committee of Deloitte, to serve as our independent registered public accounting firm for the fiscal year ending December 31, 2023. Although our Bylaws do not require that our stockholders approve the appointment of our independent registered public accounting firm, the Audit Committee is submitting the selection of Deloitte to our stockholders for ratification at the 2023 Annual General Meeting of Stockholders (the “Annual Meeting”) as a matter of good corporate practice and because we value our stockholders’ views on our independent registered public accounting firm. If our stockholders vote against the ratification of Deloitte, the Audit Committee will consider this in its selection of auditors for the following year. Even if our stockholders ratify the appointment, the Audit Committee may choose to appoint a different independent registered public accounting firm at any time during the year if it is determined that such a change would be in the interest of our Company and our stockholders.
The Audit Committee has retained Deloitte as the Company’s independent registered public accounting firm, to perform the audit of the Company’s consolidated financial statements for the fiscal year ending December 31, 2023, to be included on the Company’s annual report on Form 10-K for the same period. A representative of Deloitte is expected to be present virtually at the Annual Meeting and will have an opportunity to make a statement if he or she desires to do so and will be available to respond to appropriate questions.
Change in Independent Registered Public Accounting Firm
On May 18, 2023, the Company dismissed Marcum LLP as its independent registered public accounting firm. The Audit Committee approved the dismissal of Marcum LLP. The Audit Committee previously retained Marcum LLP to serve as the Company’s independent public accounting firm and to perform such audit services for the fiscal years ended December 31, 2018, 2019, 2020, 2021 and 2022.
Except as described below, the reports of Marcum LLP on the financial statements of Riot for the fiscal years ended December 31, 2022 and 2021 did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. Additionally, during Riot’s fiscal years ended December 31, 2022 and 2021, as well as the subsequent interim periods through May 18, 2023, there were no disagreements within the meaning of Item 304(a)(1)(iv) of Regulation S-K with Marcum LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to Marcum LLP’s satisfaction, would have caused Marcum LLP to make reference to the subject matter of the disagreements in connection with its reports on the Company’s financial statements for such fiscal years.

There were reportable events within the meaning of Item 304(a)(1)(v) of Regulation S-K during the fiscal years ended December 31, 2022 and 2021, related to the existence of a material weakness for the fiscal year ended December 31, 2022, and the existence of material weaknesses for the fiscal year ended December 31, 2021. Specifically, in the preceding two years, Marcum LLP’s report on the financial statements of the Company contained adverse opinions for the fiscal year ended December 31, 2021 regarding the Company’s IT-related user access controls, program change management controls, controls to ensure that data received from third parties pertaining to our mining revenue and Bitcoin on the balance sheet was complete and accurate, and controls relating to the inputs and assumptions of the valuation of intangible assets as identified in the accounting for our business combinations therein were reasonable. Additionally, Marcum LLP determined that there were ineffective automated process-level and manual controls that are dependent upon the information derived from financially relevant systems. For the fiscal year ended December 31, 2022, Marcum LLP’s report contained an adverse opinion regarding the Company’s control pertaining to the review of its Bitcoin for potential impairment.
Effective May 18, 2023, the Company engaged Deloitte as its new independent registered public accounting firm, commencing with the review of the financials for the quarter ending June 30, 2023, as recommended, authorized and approved by the Audit Committee. During the years ended December 31, 2022 and 2021, and the subsequent interim period through May 18, 2023, neither the Company nor anyone on its behalf consulted with Deloitte regarding either (1) the application of accounting principles to a specified transaction regarding us, either completed or proposed, or the type of audit opinion that might be rendered on our financial statements, and no written report or oral advice was provided to the Company that Deloitte concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue, or (2) any matter regarding us that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a reportable event (as defined in Item 304(a)(1)(v) of Regulation S-K).
Audit Fees
The Audit Committee current policy requires the Audit Committee’s review and pre-approval of all audit and permissible non-audit services provided by the Company’s independent auditors. These services requiring pre-approval by the Audit Committee may include audit services, audit related services, tax services and other services. All the services performed by the independent registered public accounting firm were approved by the Audit Committee and prior to performance. The Audit Committee has determined that the payments made to its independent accountants for these services are compatible with maintaining such auditors’ independence.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Auditors
All of the services performed in the years ended December 31, 2022 and December 31, 2021 were pre-approved by the Audit Committee. It is the Audit Committee’s policy to pre-approve all audit and permissible non-audit services to be provided to us by our independent registered public accounting firm. Our Audit Committee pre-approves these services by category and service. In addition, the Audit Committee has considered whether the provision of the non-audit services above is compatible with maintaining our independent registered public accounting firm’s independence.

REPORT OF THE AUDIT COMMITTEE
The following Report of our Audit Committee (this “Report”) does not constitute soliciting material and this Report should not be deemed filed or incorporated by reference into any other previous or future filings by us under the Securities Act of 1933 (the “Securities Act”), as amended, or the Securities Exchange Act of 1934 (the “Exchange Act”), as amended, except to the extent we specifically incorporate this Report by reference therein.
The role of the Audit Committee is, among other things, to assist the Board in its oversight of the following: the integrity of Riot’s financial statements; Riot’s compliance with relevant legal and regulatory requirements; Riot’s internal controls over financial reporting; the qualifications and independence of Riot’s independent registered public accounting firm; and the performance of Riot’s internal audit functions and that of its independent registered public accounting firm.
The Board has determined that, in its business judgment, all members of the Audit Committee are independent within the meaning of the Nasdaq Rules, the Sarbanes-Oxley Act of 2002 and related rules of the SEC.
Riot’s management is responsible for the preparation, presentation and integrity of Riot’s financial statements and the effectiveness of Riot’s system of internal control over financial reporting and disclosure controls and procedures. Management is responsible for maintaining and evaluating appropriate accounting and financial reporting practices and internal controls and procedures designed to ensure compliance with accounting standards and applicable laws and regulations.
The Audit Committee, on behalf of the Company, engaged Marcum LLP (“Marcum”) as its independent registered public accounting firm for the years ended December 31, 2018, 2019, 2020, 2021, and 2022. Pursuant to its appointment, Marcum was responsible for auditing Riot’s consolidated financial statements and expressing an opinion as to whether such financial statements are presented fairly, in all material respects, in conformity with accounting principles generally accepted in the United States. Marcum was also responsible for auditing the effectiveness of Riot’s internal control over financial reporting for the years ended December 31, 2018, 2019, 2021 and 2022. Effective May 18, 2023, the Audit Committee, on behalf of the Company, engaged Deloitte & Touche (“Deloitte”), and dismissed Marcum, for the year ending December 31, 2023. Pursuant to its appointment, Deloitte is now responsible for auditing Riot’s consolidated financial statements and expressing an opinion as to whether such financial statements are presented fairly, in all material respects, in conformity with accounting principles generally accepted in the United States. Deloitte is also now responsible for auditing the effectiveness of Riot’s internal control over financial reporting for the year ending December 31, 2023.
Prior to Marcum’s dismissal, the Audit Committee met and held discussions with the Company’s management and Marcum. The Audit Committee discussed with the Company’s management and Marcum the overall scope of, and plans for, their respective audits and the identification of audit risks. The Audit Committee also met with Marcum, with and without management present, to discuss the results of their respective examinations, the reasonableness of significant judgments, the evaluations of Riot’s internal controls over financial reporting and the overall quality of Riot’s financial reporting. Management has represented to the Audit Committee that Riot’s consolidated financial statements were prepared in accordance with U.S. Generally Accepted Accounting Principles.
In the performance of its oversight function, the Audit Committee has:
Reviewed and discussed Riot’s internal controls over financial reporting with management and Marcum, including a review of management’s report on its assessment and for the year ended December 31, 2022, Marcum’s audit of the effectiveness of Riot’s internal controls over financial reporting and any significant deficiencies or material weaknesses identified by such audit;
Considered, reviewed and discussed the audited financial statements with management and Marcum, including a discussion of the quality of the accounting principles, the reasonableness thereof, significant adjustments, if any, and the clarity of disclosures in the financial statements, as well as critical accounting policies and other financial accounting and reporting principles and practices;
Discussed with Marcum the matters required to be discussed under the Public Company Accounting Oversight Board Auditing Standard No. 1301, Communications with Audit Committees, and No. 2410, Related Parties;

Received, reviewed and discussed the written disclosures and the letter from Marcum required by applicable requirements of the Public Company Accounting Oversight Board regarding Marcum’s communications with the Audit Committee concerning independence, and has discussed with Marcum its independence; and
Reviewed the services provided by Marcum other than its audit services and considered whether the provision of such other services by Marcum is compatible with maintaining its independence, discussed with Marcum its independence, and concluded that Marcum is independent from Riot and its management.
In reliance on the reports, reviews and discussions described in this Report, the Audit Committee has recommended to the Board, and the Board has approved, that the audited financial statements be included in Riot’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, for filing with the SEC and for inclusion in the Company’s proxy materials to be provided to the Company’s stockholders in advance of its annual stockholders’ meeting for the year ending December 31, 2023. The Audit Committee also has appointed, and has requested stockholder ratification of the appointment of, Deloitte as Riot’s new independent registered public accounting firm for the fiscal year ending December 31, 2023.
